Topical gene therapy for dystrophic epidermolysis bullosa shows promise
INDIANAPOLIS – An investigational compared with placebo, according to results from a small phase 3 study.
DEB is a serious, ultra-rare genetic blistering disease caused by mutations in the COL7A1 gene, encoding for type VII collagen and leading to skin fragility and wounds. No approved therapies are currently available. In the study, treatment was generally well tolerated.
“B-VEC is the first treatment that has not only been shown to be effective, but the first to directly target the defect through topical application,” the study’s principal investigator, Shireen V. Guide, MD, said in an interview during a poster session at the annual meeting of the Society for Pediatric Dermatology. “It delivers type VII collagen gene therapy to these patients, which allows healing in areas that they may have had open since birth. It’s been life-changing for them.”
B-VEC is a herpes simplex virus (HSV-1)-based topical, redosable gene therapy being developed by Krystal Biotech that is designed to restore functional COL7 protein by delivering the COL7A1 gene. For the phase 3, multicenter, double-blind, placebo-controlled study known GEM-3, Dr. Guide, who practices dermatology in Rancho Santa Margarita, Calif., and her colleagues, including Peter Marinkovich, MD, from Stanford (Calif.) University, and Mercedes Gonzalez, MD, from the University of Miami, enrolled 31 patients aged 6 months and older with genetically confirmed DEB. Each patient had one wound treated randomized 1:1 to treatment with B-VEC once a week or placebo for 6 months. The mean age of the 31 study participants was 17 years, 65% were male, 65% were White, and 19% were Asian.
The primary endpoint was complete wound healing (defined as 100% wound closure from exact wound area at baseline, specified as skin re-epithelialization without drainage) at 6 months. Additional endpoints included complete wound healing at 3 months and change in pain associated with wound dressing changes.
At 3 months, 70% of wounds treated with B-VEC met the endpoint of complete wound healing, compared with 20% of wounds treated with placebo (P < .005). At 6 months, 67% of wounds treated with B-VEC met the endpoint of complete wound healing compared with 22% of those treated with placebo (P < .005).
Of the total wounds that closed at 3 months, 67% of wounds treated with B-VEC were also closed at 6 months, compared with 33% of those treated with placebo (P = .02). In other findings, a trend toward decreased pain was observed in wounds treated with B-VEC vs. those treated with placebo.
B-VEC was well tolerated with no treatment-related serious adverse events or discontinuations. Three patients experienced a total of five serious adverse events during the study: anemia (two events), and cellulitis, diarrhea, and positive blood culture (one event each). None were considered related to the study drug.
Dr. Guide, who is on staff at Children’s Health of Orange County, Orange, Calif., characterized B-VEC as “very novel because it’s very practical.”
To date, all treatments for DEB “have been extremely labor intensive, including skin grafting and hospitalizations. It’s a topical application that can be done in the office and potentially applied at home in the future. It’s also durable. Not only are the [treated] areas closing, but they are staying closed.”
Kalyani S. Marathe, MD, MPH, director of the dermatology division at Cincinnati Children’s Hospital, who was asked to comment on the study, said that topical application of B-VEC “allows the side effect profile to be very favorable. The results are remarkable in the amount of wound healing and reduction in pain.”
The tolerability of this medication “is crucial,” she added. “EB patients have a lot of pain from their wounds and so any treatment needs to be as painless as possible for it to be usable. I’m very excited about the next phase of studies for this medication and hopeful that it heralds new treatments for our EB patients.”
In June 2022, the manufacturer announced that it had submitted a biologics license application to the Food and Drug Administration for approval of B-VEC for the treatment of DEB, and that it anticipates submitting an application for marketing authorization with the European Medical Agency (EMA) in the second half of 2022.
Dr. Guide disclosed that she has served as an investigator for Krystal Biotech, Innovaderm Research, Arcutis, Premier Research, Paidion, and Castle Biosciences. Dr. Marathe disclosed that she has served as an adviser for Verrica, and that Cincinnati Children’s Hospital is a site for the next phase studies for B-VEC.

Clinical characteristics of recurrent RIME elucidated in chart review
INDIANAPOLIS – , in a single-center retrospective study. In addition, 71% of patients with recurrent disease experienced 1-2 recurrences – episodes that were generally milder and occurred at variable intervals.
Those are among key findings from the study of 50 patients with RIME, presented by Catherina X. Pan at the annual meeting of the Society for Pediatric Dermatology.
Reactive infectious mucocutaneous eruption (RIME) is a novel term encompassing an array of rare, parainfectious mucositis diseases, noted Ms. Pan, a fourth-year medical student at Harvard Medical School, Boston. Previously known as Mycoplasma pneumoniae-induced rash and mucositis (MIRM), common clinical characteristics of RIME include less than 10% body surface area involvement of polymorphic skin lesions (vesiculobullous or targetoid macules/papules); erosive oral, genital, and/or ocular mucositis involving more than two sites, and evidence of prior infection including but not limited to upper respiratory infection, fever, and cough.
In addition to M. pneumoniae, other pathogens have been implicated, she said. “While the underlying etiology of the disease is not entirely clear, it’s become increasingly known that RIME tends to recur in a subset of patients.”
A cohort study of 13 patients with RIME found that Black race, male sex, and older age were predominant among the five patients who developed recurrent disease.
The estimated recurrence rate is between 8% and 38%, but the clinical characteristics of patients who develop recurrent RIME tend to be poorly understood, Ms. Pan said.
Along with her mentor, Sadaf Hussain, MD, of the department of dermatology at Boston Children’s Hospital, Ms. Pan conducted a retrospective chart review to characterize the clinical history and course of disease in patients diagnosed with recurrent RIME. They extracted data between January of 2000 and March of 2022 using ICD-10 codes used by board-certified dermatologists at Boston Children’s Hospital, as well as a text search for RIME or MIRM in the dermatology notes. Patients were included if they had a RIME/MIRM diagnosis by a board-certified dermatologist and/or infection on PCR/serology and mucositis involvement with limited skin involvement.
The study population included 50 patients: 24 with recurrent RIME and 26 with isolated RIME. The majority (66%) were male, and the mean age of RIME onset was between 11 and 12 years old, which is up to two years younger than previously reported in the case series of 13 patients. Most of the study participants (79%) were White, but there were no significant differences in patients who had recurrent RIME and those who had isolated RIME in terms of age, sex, or race.
Isolated vs. recurrent RIME
However, compared with patients who had isolated RIME, a greater proportion of those with recurrent RIME had a history of atopic disease (46% vs. 23%, respectively; P = .136), as well as a history of tonsillectomy and adenoidectomy (25% vs. 4%; P = .045). “This has not been previously observed, but it may generate a hypothesis that patients with a history of frequent infection as well as amplified immune responses may be associated with disease recurrence,” Ms. Pan said.
The average number of episodes among patients with recurrent RIME was 3.5 and the interval between episodes was variable, at a mean of 10.2 months. Ms. Pan reported that 71% of recurrent RIME patients experienced 1-2 episodes, although one patient experienced 9 episodes.
Clinically, episodes among all patients with RIME were characterized by infectious prodromal symptoms (69%), oral lesions (95%), ocular lesions (60%), genital lesions (41%) and cutaneous lesions (40%). However, RIME recurrences were less severe and more atypical, with 49% involving only one mucosal surface and 29% involving two mucosal surfaces. Also, except for oral lesions, rates of infectious prodromal symptoms and other lesions significantly decreased among recurrences compared with initial RIME.
“Notably, we found that M. pneumoniae was the most common known cause of RIME, particularly among the initial episodes,” Ms. Pan said. “However, 61% of recurrent RIME episodes did not have a known cause in terms of infectious etiology. And, concordant with prior studies, we also found decreased severity [of RIME recurrences] as indicated by decreased rates of emergency department presentation, hospitalization, and duration of hospitalization.”
In other findings, psychiatric complications such as anxiety and depression followed the onset of RIME in 33% of those with recurrent disease and 22% of those with isolated disease. In addition, the three most common treatments among all 50 patients were systemic steroids, topical steroids, and M. pneumoniae-specific antibiotics.
“While RIME is considered as typically milder than Stevens-Johnson syndrome and toxic epidermal necrolysis with low mortality rates, it can lead to severe complications including conjunctival shrinkage, corneal ulceration and scarring, blindness, and oral, ocular, urogenital synechiae,” Ms. Pan noted. “Increased use of corticosteroids and steroid-sparing agents such as IVIG have also been observed. Multidisciplinary care with ophthalmology, urology, and mental health services is critical.”
She acknowledged certain limitations of the study, including its retrospective, single-center design, and the possibility that milder cases may have been excluded due to a lack of accurate diagnosis or referral.
Carrie C. Coughlin, MD, who was asked to comment on the study results, pointed out that nearly half (24) of patients in the cohort experienced recurrent RIME. “This is a high proportion, suggesting counseling about the possibility of recurrence is more important than previously thought,” said Dr. Coughlin, director of the section of pediatric dermatology Washington University/St. Louis Children’s Hospital.
“Fortunately, recurrent cases tended to be less severe. However, many patients had more than one recurrence, making this challenging for affected patients.”
The researchers reported having no financial disclosures. Dr. Coughlin is on the board of the Pediatric Dermatology Research Alliance (PeDRA) and the International Immunosuppression and Transplant Skin Cancer Collaborative.

A toddler presents with patchy hair loss
Given the history of sudden hair loss, with the exam revealing a well-circumscribed patch of focal alopecia without cutaneous inflammation, hairs with a narrow base and broad distal shaft, the diagnosis is alopecia areata (AA).
Alopecia areata (AA) is a nonscarring alopecia, within a set of diseases characterized by the preservation of hair follicles and therefore the potential for future hair regrowth.1 AA is believed to be caused by a breakdown of the immune-privileged nature of hair follicles, resulting in T-lymphocytes targeting the hair follicle directly, shifting follicles to early catagen or telogen phase, but sparing follicular stem cells, thereby allowing the follicle to regenerate in the future.1-3 Risk factors include family history of AA, thyroid disorders, as well as iron and vitamin D deficiency.4,5 It characteristically presents with focal, well-demarcated patches of hair loss in the scalp, typically with background skin normal to slightly pink.3,6 Exam can show “exclamation point” hairs consisting of hairs that are narrow at their base and wide at the distal end.3,7 Patients may also exhibit eyebrow and eyelash loss as well as nail changes including nail pitting and splitting.8 Diagnosis is typically made clinically but is supported by a positive hair pull test, where hairs are pulled from the periphery of an alopecic lesion; the presence of greater than 10% of hairs plucked from the scalp indicates a positive result.9,10
What’s the differential diagnosis?
The differential diagnosis of AA includes other nonscarring alopecias such as trichotillomania and telogen effluvium. Other possible diagnoses include lichen planopilaris and tinea capitis.
Trichotillomania results in irregularly bordered hair loss and broken hairs of different lengths because of an internal urge to remove one’s hair, resulting in nonscarring alopecia. It can be associated with obsessive-compulsive disorder, anxiety, or other body-altering behaviors like skin picking and nail biting (characterized as body-focused repetitive behavior disorders). Treatments include reassurance and education, behavior modification, or systemic therapy including tricyclic antidepressants or SSRIs. Toddlers can engage in hair pulling behavior and trichotillomania can be difficult to differentiate from AA. However, the absence of broken hairs of varying lengths makes trichotillomania less likely in this patient.
Telogen effluvium is another form of nonscarring alopecia that presents as diffuse hair thinning across the entire scalp in response to acute psychological or physiological stress, hormonal changes, certain medications, systemic illness, or nutritional deficiency. The timing between the triggering event and hair loss can vary from weeks to months. Diagnosis requires detailed history-taking and may include evaluation for endocrinologic hair thinning (e.g. thyroid function tests) to identify reversible causes. Treatment involves directing therapy to the underlying etiology and most cases of telogen effluvium are self-limited. The presence of a well-circumscribed patch of hair loss in this patient makes AA more likely.
Lichen planopilaris (LPP) is a scarring, irreversible alopecia caused by T-lymphocytes attacking follicular hair stem cells. It is characterized by hair loss, pruritus, burning pain, scalp scaling, and multifocal scarring. Exam shows patches of alopecia with loss of follicular ostia centrally and perifollicular scale and erythema at the borders. Diagnosis is aided by biopsy of the affected scalp. Treatment of LPP requires the use of potent and superpotent topical corticosteroids and intralesional corticosteroids to decrease scalp inflammation and prevent further progression. The presence of follicular ostia and absence of perifollicular scale in this patient makes LPP highly unlikely.
Tinea capitis is a fungal infection of the scalp caused by dermatophytes including Trychophyton tonsurans and Microsporum canis. It presents with patches of alopecia with overlying scale and broken hairs and can have associated cervical and occipital lymphadenopathy. Diagnosis can involve skin scraping and KOH prep to visualize branching hyphae as well as fungal culture to identify the causative organism. Because dermatophytes in tinea capitis invade hair follicles, topical antifungals are ineffective because of their lack of penetration. Therefore, systemic antifungals including oral terbinafine and griseofulvin are considered first-line agents for treatment.
What’s the management plan?
The diagnosis of AA is usually a clinical one, though assessment of alternative diagnoses is appropriate dependent on signs and symptoms. Workup of AA can include thyroid studies because of the association with autoimmune thyroid disease, though studies suggest limited screening benefits in children.11 Given its variable and unpredictable course, management can include “watchful waiting” because of its potential for spontaneous remission.6 For limited patchy loss, active treatment with mid to superpotent topical steroids or intralesional triamcinolone acetonide in older children and adolescents is reasonable.12 Other treatment options include topical or low-dose oral minoxidil and immunotherapy with diphenylcyclopropenone or squaric acid (inducing an allergic contact dermatitis).12 Management of therapies for more extensive AA is evolving, with ongoing studies of oral JAK-inhibitors and biologic agents.12,13
Our patient was started on topical fluocinonide 0.05% solution and achieved good disease control and hair regrowth over the course of 3 months.

Given the history of sudden hair loss, with the exam revealing a well-circumscribed patch of focal alopecia without cutaneous inflammation, hairs with a narrow base and broad distal shaft, the diagnosis is alopecia areata (AA).
Alopecia areata (AA) is a nonscarring alopecia, within a set of diseases characterized by the preservation of hair follicles and therefore the potential for future hair regrowth.1 AA is believed to be caused by a breakdown of the immune-privileged nature of hair follicles, resulting in T-lymphocytes targeting the hair follicle directly, shifting follicles to early catagen or telogen phase, but sparing follicular stem cells, thereby allowing the follicle to regenerate in the future.1-3 Risk factors include family history of AA, thyroid disorders, as well as iron and vitamin D deficiency.4,5 It characteristically presents with focal, well-demarcated patches of hair loss in the scalp, typically with background skin normal to slightly pink.3,6 Exam can show “exclamation point” hairs consisting of hairs that are narrow at their base and wide at the distal end.3,7 Patients may also exhibit eyebrow and eyelash loss as well as nail changes including nail pitting and splitting.8 Diagnosis is typically made clinically but is supported by a positive hair pull test, where hairs are pulled from the periphery of an alopecic lesion; the presence of greater than 10% of hairs plucked from the scalp indicates a positive result.9,10
What’s the differential diagnosis?
The differential diagnosis of AA includes other nonscarring alopecias such as trichotillomania and telogen effluvium. Other possible diagnoses include lichen planopilaris and tinea capitis.
Trichotillomania results in irregularly bordered hair loss and broken hairs of different lengths because of an internal urge to remove one’s hair, resulting in nonscarring alopecia. It can be associated with obsessive-compulsive disorder, anxiety, or other body-altering behaviors like skin picking and nail biting (characterized as body-focused repetitive behavior disorders). Treatments include reassurance and education, behavior modification, or systemic therapy including tricyclic antidepressants or SSRIs. Toddlers can engage in hair pulling behavior and trichotillomania can be difficult to differentiate from AA. However, the absence of broken hairs of varying lengths makes trichotillomania less likely in this patient.
Telogen effluvium is another form of nonscarring alopecia that presents as diffuse hair thinning across the entire scalp in response to acute psychological or physiological stress, hormonal changes, certain medications, systemic illness, or nutritional deficiency. The timing between the triggering event and hair loss can vary from weeks to months. Diagnosis requires detailed history-taking and may include evaluation for endocrinologic hair thinning (e.g. thyroid function tests) to identify reversible causes. Treatment involves directing therapy to the underlying etiology and most cases of telogen effluvium are self-limited. The presence of a well-circumscribed patch of hair loss in this patient makes AA more likely.

Examination findings of the scalp demonstrate a well-circumscribed alopecic patch on the vertex scalp without erythema or scale. Closer inspection of the patch with magnification or 'dermoscopy' reveals hair follicle ostia and hairs that are broader distally and narrower at their base. Nails and rest of the skin exam are unremarkable.
Leg lesions
A 4-mm punch biopsy performed on the central portion of a lesion revealed thickening of the epidermis and altered collagen in the dermis consistent with acquired reactive perforating collagenosis (ARPC).
ARPC is strongly associated with diabetes, renal disease, and malignancy. ARPC manifests as an eruption of intensely pruritic papules to small plaques (with a central plug or firm dry depression) on the trunk, or more commonly, on the extremities. The etiology is unclear but altered collagen from systemic disease, trauma, or cold exposure may trigger collagen elimination.1 Secondary infection may occur due to the intensity of itching. ARPC develops in adulthood; epidemiologic data are lacking and prevalence has not been systematically assessed.2
Treatment approaches are based on small case reports and case series. Common antipruritic therapies, such as topical and intralesional steroids, oral antihistamines, and vitamin-D analogues, have had mixed success. UV therapy is effective for nephrogenic pruritus; case reports suggest it has also been helpful for ARPC. Similarly, keratolytics and topical and systemic retinoids have shown promise. Allopurinol, which reduces free radicals, has also demonstrated its utility.3
This patient was started on topical triamcinolone 0.1% cream bid and narrowband UV-B phototherapy 3 times weekly with marked improvement in her itching. Lesions decreased in number over 3 months of follow-up but did not completely resolve.

Milium cysts on hands; hypertrichosis on face
A 55-YEAR-OLD MAN with hypertension and untreated hepatitis C virus (HCV) was referred to the Dermatology Clinic after reporting a 2-year history of photosensitivity and intermittent episodes of blistering and scars on the dorsal side of his hands and feet. No alcohol consumption or drug use was reported.
Physical examination revealed small and shallow erosions on the dorsal aspect of the hands and feet (but no visible blisters) and milium cysts (FIGURE 1A). Additionally, hypertrichosis and hyperpigmentation were observed in the zygomatic areas (FIGURE 1B). Complete blood count and kidney function test results were within normal ranges. Liver function tests showed slightly elevated levels of alanine aminotransferase (79 U/L; normal range, 0-41 U/L), aspartate aminotransferase (62 U/L; normal range, 0-40 U/L), and ferritin (121 ng/mL; normal range, 30-100 ng/mL). Serologies for syphilis, HIV, and hepatitis B virus were negative.
WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?
Diagnosis: Porphyria cutanea tarda
The porphyrias are a group of metabolic diseases that affect the heme biosynthesis. They can be classified into 1 of 3 groups, according to clinical features:
- acute hepatic porphyrias, with neurovisceral symptoms (eg, acute intermittent porphyria),
- nonblistering cutaneous porphyrias, with severe photosensitivity but without bullae formation (eg, erythropoietic protoporphyria), or
- blistering cutaneous porphyrias (eg, PCT, hepatoerythropoietic porphyria, and variegate porphyria).
PCT is the most common type of porphyria, with a global prevalence of 1 per 10,000 people.1,2 It affects adults after the third or fourth decade of life.
PCT involves dysfunction of the uroporphyrinogen decarboxylase enzyme (UROD), the fifth enzyme in heme biosynthesis, which catalyzes the conversion of uroporphyrinogen to coproporphyrinogen. This dysfunction causes the accumulation of porphyrinogens that are auto-oxidized to photosensitizing porphyrins.1-4 PCT can be classified as “sporadic” or “familial” based on the absence or presence of UROD mutation. Approximately 80% of cases of PCT are sporadic.2
In sporadic PCT, triggers for UROD dysfunction include alcohol use, use of estrogens, hemochromatosis or iron overload, chronic HCV infection, and HIV infection.1-4 HCV (which this patient had) is the most common infection associated with sporadic PCT, with a prevalence of about 50% among these patients.5
Continue to: Dermatologic manifestations of PCT
Dermatologic manifestations of PCT include photosensitivity, skin fragility, vesicles, bullae, erosions, and crusts observed in sun-exposed areas. A nonvirilizing type of hypertrichosis may appear prominently on the temples and the cheeks.2-4 After blisters rupture, atrophy and scarring occur. Milia cysts can form on the dorsal side of the hands and fingers. Less common manifestations include pruritus, scarring alopecia, sclerodermatous changes, and periorbital purple-red suffusion.
Hepatic involvement is demonstrated with elevated serum transaminases and gamma-glutamyl transpeptidase. Hepatomegaly is common, and cirrhosis manifests in 30% to 40% of patients.2-5 On liver biopsy, some degree of siderosis is found in 80% of patients with PCT, and most of them have increased levels of serum iron. The incidence of hepatocellular carcinoma in patients with PCT is greater than in patients with other liver diseases.2
A Wood lamp can be a useful diagnostic first step
Plasma or urine porphyrin lab tests are the gold standard for PCT diagnosis. These tests can be followed by more specific tests (eg, porphyrin fractionation) to exclude other forms of porphyria. However, if plasma or urine porphyrin testing is not readily available, a good first step is a Wood lamp exam, which can be performed on urine or stool. (Plasma or urine porphyrin testing may ultimately be necessary if there is doubt about the diagnosis following the Wood lamp screening.) Histopathologic examination does not confirm the diagnosis of PCT4; however, it can be helpful in differential diagnosis.
Wood lamp is a source of long-wave UV light (320 to 400 nm), visualized as a purple or violet light. When porphyrins are present in a urine sample, a red-pink fluorescence may be seen.3,4,6 The Wood lamp examination should be performed in a completely dark room after the lamp has been warmed up for about 1 minute; time should be allowed for the clinician’s vision to adapt to the dark.6 There are no data regarding the sensitivity or specificity of the Wood lamp test in the diagnosis of PCT.
These conditions also cause skin fragility and photosensitivity
The differential diagnosis for PCT includes diseases that also cause skin fragility, blistering, or photosensitivity, such as pseudoporphyria, bullous systemic lupus erythematosus (SLE), and epidermolysis bullosa acquisita (EBA).3
Continue to: In pseudoporphyria
In pseudoporphyria, the clinical findings may be indistinguishable from PCT. Thus, the patient’s history will be especially important; suspect pseudoporphyria if the patient has a history of chronic renal failure or use of a photosensitizing drug.1,3
Bullous SLE usually manifests with systemic involvement and widespread, tense bullae. Serologic investigation will demonstrate the presence of antinuclear antibodies in high titers (> 1:80), as well as other circulating autoantibodies.
Skin lesions of EBA usually manifest with skin fragility and noninflammatory tense bullae in traumatized skin, such as the extensor surfaces of the hands, feet, and fingers.
None of the above-mentioned diagnoses manifest with hypertrichosis or red-pink fluorescent urine on Wood lamp, and results of porphyrin studies would be normal.3
Address triggers, provide treatment
Once the diagnosis is confirmed, steps must be taken to avoid triggering factors, such as any alcohol consumption, use of estrogen, sun exposure (until plasma porphyrin levels are normal), and potential sources of excessive iron intake.
Two therapeutic options are available for treating PCT—whether it’s sporadic or familial. Phlebotomy sessions reduce iron overload and iron depletion and may prevent the formation of a porphomethene inhibitor of UROD. The other treatment option is antimalarial agents—usually hydroxychloroquine— and is indicated for patients with lower serum ferritin levels.1-4 In patients with HCV-associated PCT, effective treatment of the infection has resulted in resolution of the PCT, in some cases.3
Treatment involving phlebotomy or an antimalarial agent can be stopped when plasma porphyrins reach normal levels.
Our patient was initially managed with 2 sessions of phlebotomy. He subsequently received treatment for the HCV infection at another hospital.

A 55-YEAR-OLD MAN with hypertension and untreated hepatitis C virus (HCV) was referred to the Dermatology Clinic after reporting a 2-year history of photosensitivity and intermittent episodes of blistering and scars on the dorsal side of his hands and feet. No alcohol consumption or drug use was reported.
Physical examination revealed small and shallow erosions on the dorsal aspect of the hands and feet (but no visible blisters) and milium cysts (FIGURE 1A). Additionally, hypertrichosis and hyperpigmentation were observed in the zygomatic areas (FIGURE 1B). Complete blood count and kidney function test results were within normal ranges. Liver function tests showed slightly elevated levels of alanine aminotransferase (79 U/L; normal range, 0-41 U/L), aspartate aminotransferase (62 U/L; normal range, 0-40 U/L), and ferritin (121 ng/mL; normal range, 30-100 ng/mL). Serologies for syphilis, HIV, and hepatitis B virus were negative.

Diagnosis: Porphyria cutanea tarda
The porphyrias are a group of metabolic diseases that affect the heme biosynthesis. They can be classified into 1 of 3 groups, according to clinical features:
- acute hepatic porphyrias, with neurovisceral symptoms (eg, acute intermittent porphyria),
- nonblistering cutaneous porphyrias, with severe photosensitivity but without bullae formation (eg, erythropoietic protoporphyria), or
- blistering cutaneous porphyrias (eg, PCT, hepatoerythropoietic porphyria, and variegate porphyria).
PCT is the most common type of porphyria, with a global prevalence of 1 per 10,000 people.1,2 It affects adults after the third or fourth decade of life.
PCT involves dysfunction of the uroporphyrinogen decarboxylase enzyme (UROD), the fifth enzyme in heme biosynthesis, which catalyzes the conversion of uroporphyrinogen to coproporphyrinogen. This dysfunction causes the accumulation of porphyrinogens that are auto-oxidized to photosensitizing porphyrins.1-4 PCT can be classified as “sporadic” or “familial” based on the absence or presence of UROD mutation. Approximately 80% of cases of PCT are sporadic.2
In sporadic PCT, triggers for UROD dysfunction include alcohol use, use of estrogens, hemochromatosis or iron overload, chronic HCV infection, and HIV infection.1-4 HCV (which this patient had) is the most common infection associated with sporadic PCT, with a prevalence of about 50% among these patients.5
Continue to: Dermatologic manifestations of PCT
Dermatologic manifestations of PCT include photosensitivity, skin fragility, vesicles, bullae, erosions, and crusts observed in sun-exposed areas. A nonvirilizing type of hypertrichosis may appear prominently on the temples and the cheeks.2-4 After blisters rupture, atrophy and scarring occur. Milia cysts can form on the dorsal side of the hands and fingers. Less common manifestations include pruritus, scarring alopecia, sclerodermatous changes, and periorbital purple-red suffusion.
Hepatic involvement is demonstrated with elevated serum transaminases and gamma-glutamyl transpeptidase. Hepatomegaly is common, and cirrhosis manifests in 30% to 40% of patients.2-5 On liver biopsy, some degree of siderosis is found in 80% of patients with PCT, and most of them have increased levels of serum iron. The incidence of hepatocellular carcinoma in patients with PCT is greater than in patients with other liver diseases.2
A Wood lamp can be a useful diagnostic first step
Plasma or urine porphyrin lab tests are the gold standard for PCT diagnosis. These tests can be followed by more specific tests (eg, porphyrin fractionation) to exclude other forms of porphyria. However, if plasma or urine porphyrin testing is not readily available, a good first step is a Wood lamp exam, which can be performed on urine or stool. (Plasma or urine porphyrin testing may ultimately be necessary if there is doubt about the diagnosis following the Wood lamp screening.) Histopathologic examination does not confirm the diagnosis of PCT4; however, it can be helpful in differential diagnosis.
Wood lamp is a source of long-wave UV light (320 to 400 nm), visualized as a purple or violet light. When porphyrins are present in a urine sample, a red-pink fluorescence may be seen.3,4,6 The Wood lamp examination should be performed in a completely dark room after the lamp has been warmed up for about 1 minute; time should be allowed for the clinician’s vision to adapt to the dark.6 There are no data regarding the sensitivity or specificity of the Wood lamp test in the diagnosis of PCT.
These conditions also cause skin fragility and photosensitivity
The differential diagnosis for PCT includes diseases that also cause skin fragility, blistering, or photosensitivity, such as pseudoporphyria, bullous systemic lupus erythematosus (SLE), and epidermolysis bullosa acquisita (EBA).3
Continue to: In pseudoporphyria
In pseudoporphyria, the clinical findings may be indistinguishable from PCT. Thus, the patient’s history will be especially important; suspect pseudoporphyria if the patient has a history of chronic renal failure or use of a photosensitizing drug.1,3
Bullous SLE usually manifests with systemic involvement and widespread, tense bullae. Serologic investigation will demonstrate the presence of antinuclear antibodies in high titers (> 1:80), as well as other circulating autoantibodies.
Skin lesions of EBA usually manifest with skin fragility and noninflammatory tense bullae in traumatized skin, such as the extensor surfaces of the hands, feet, and fingers.
None of the above-mentioned diagnoses manifest with hypertrichosis or red-pink fluorescent urine on Wood lamp, and results of porphyrin studies would be normal.3
Address triggers, provide treatment
Once the diagnosis is confirmed, steps must be taken to avoid triggering factors, such as any alcohol consumption, use of estrogen, sun exposure (until plasma porphyrin levels are normal), and potential sources of excessive iron intake.
Two therapeutic options are available for treating PCT—whether it’s sporadic or familial. Phlebotomy sessions reduce iron overload and iron depletion and may prevent the formation of a porphomethene inhibitor of UROD. The other treatment option is antimalarial agents—usually hydroxychloroquine— and is indicated for patients with lower serum ferritin levels.1-4 In patients with HCV-associated PCT, effective treatment of the infection has resulted in resolution of the PCT, in some cases.3
Treatment involving phlebotomy or an antimalarial agent can be stopped when plasma porphyrins reach normal levels.
Our patient was initially managed with 2 sessions of phlebotomy. He subsequently received treatment for the HCV infection at another hospital.

NAFLD strongly correlated with psoriasis, PsA; risk linked to severity
NEW YORK – – and probably in those with psoriatic arthritis (PsA) as well, according to a systematic review and meta-analysis presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
“Our findings imply that psoriatic patients should be screened with an ultrasonographic exam in cases where there are metabolic features that are associated with NAFLD,” reported Francesco Bellinato, MD, a researcher in the section of dermatology and venereology, University of Verona (Italy).
The data are strong. Of 76 nonduplicate publications found in the literature, the 11 observational studies included in the meta-analysis met stringent criteria, including a diagnosis of psoriasis and PsA based on objective criteria, NAFLD confirmed with liver biopsy or imaging, and odds rates calculated with 95% confidence intervals.
From these 11 studies, aggregate data were available for 249,333 psoriatic patients, of which 49% had NAFLD, and 1,491,402 were healthy controls. Among the controls, 36% had NAFLD. Four of the studies were from North America, four from Europe, and three from Asia.
In the pooled data, the risk of NAFLD among those with psoriasis relative to healthy controls fell just short of a twofold increase (odds ratio, 1.96; 95% CI, 1.70-2.26; P < .001). When stratified by studies that confirmed NAFLD by biopsy relative to ultrasonography, there was no significant heterogeneity.
Eight of the studies included an analysis of relative risk in the context of skin lesion severity defined by Psoriasis Area and Severity Index (PASI) score. Relative to those without NAFLD, psoriatic patients with NAFLD had a significant greater mean PASI score on a pooled weighted mean difference analysis (OR, 3.93; 95% CI, 2.01-5.84; P < .0001).
For PsA relative to no PsA in the five studies that compared risk between these two groups, the risk of NAFLD was again nearly twofold higher. This fell short of conventional definition of statistical significance, but it was associated with a strong trend (OR, 1.83; 95% CI, 0.98-3.43; P = .06).
The risk of NAFLD among patients with psoriasis was not found to vary significantly when assessed by univariable meta-regressions across numerous characteristics, such as sex and body mass index.
In one of the largest of the observational studies included in the meta-analysis by Alexis Ogdie, MD, associate professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia, and colleagues, data were analyzed in more than 1.5 million patients, which included 54,251 patients with rheumatoid arthritis. While the hazard ratio of NAFLD was increased for both psoriasis (HR, 2.23) and PsA (HR, 2.11), it was not elevated in those with RA (HR, 0.96).
Risk by severity, possible mechanisms
This study also included an analysis of NAFLD risk according to psoriasis severity. While risk was still significant among those with mild disease (HR, 1.18; 95% CI, 1.07-1.30), it was almost twofold greater in those with moderate to severe psoriasis (HR, 2.23; 95% CI, 1.73-2.87).
Dr. Bellinato conceded that the mechanisms underlying the association between psoriasis and NAFLD are unknown, but he said “metaflammation” is suspected.
“The secretion of proinflammatory, prothrombotic, and oxidative stress mediators in both psoriatic skin and adipose tissue might act systemically and promote insulin resistance and other metabolic derangements that promote the development and progression of NAFLD,” Dr. Bellinato explained.
He thinks that noninvasive screening methods, such as currently used methods to calculate fibrosis score, might be useful for evaluating patients with psoriasis for NAFLD and referring them to a hepatologist when appropriate.
Given the strong association with NAFLD, Dr. Bellinato suggested that “the findings of this meta-analysis pave the way for novel, large, prospective, and histologically based studies.”
The association between psoriasis and NAFLD is clinically relevant, agreed Joel M. Gelfand, MD, vice-chair of clinical research and medical director of the clinical studies unit, department of dermatology, University of Pennsylvania, Philadelphia.
“It is not clear if psoriasis causes fatty liver disease or vice versa, but clinicians should be aware of this association,” he said in an interview. Dr. Gelfand was a coauthor of the study by Dr. Ogdie and colleagues and led another more recent population-based study that implicated methotrexate as a factor in psoriasis-related hepatotoxicity.
If NAFLD is identified in a patient with psoriasis, treatments are limited, but Dr. Gelfand suggested that patients should be made aware of the risk. “Clinicians should encourage patients with psoriasis to take measures to protect their liver, such as avoiding drinking alcohol to excess and trying to maintain a healthy body weight,” he said.
Dr. Bellinato reported no conflicts of interest. Dr. Gelfand has financial relationships with more than 10 pharmaceutical companies, including those that make therapies for psoriasis.

FDA approves topical ruxolitinib for nonsegmental vitiligo
The on July 18. The treatment, which was approved for treating mild to moderate atopic dermatitis in September 2021, is a cream formulation of ruxolitinib, a Janus kinase 1 (JAK1)/JAK2 inhibitor.
Previously, no treatment was approved to repigment patients with vitiligo, says David Rosmarin, MD, vice chair for research and education in the department of dermatology at Tufts Medical Center, Boston. “It’s important to have options that we can give to patients that are both safe and effective to get them the desired results,” Dr. Rosmarin, the lead investigator of the phase 3 clinical trials of topical ruxolitinib, said in an interview. Vitiligo is “a disease that can really affect quality of life. Some people [with vitiligo] feel as if they’re being stared at or they’re being bullied; they don’t feel confident. It can affect relationships and intimacy.”
Approval was based on the results of two phase 3 trials (TruE-V1 and TruE-V2) in 674 patients with nonsegmental vitiligo aged 12 years or older. At 24 weeks, about 30% of the patients on treatment, applied twice a day, achieved at least a 75% improvement in the facial Vitiligo Area Scoring Index (F-VASI75), compared with about 8% and 13% among those in the vehicle groups in the two trials.
At 52 weeks, about 50% of the patients treated with topical ruxolitinib achieved F-VASI75.
Also, using self-reporting as measured by the Vitiligo Noticeability Scale, about 30%-40% of patients described their vitiligo as being “a lot less noticeable” or “no longer noticeable” at week 52. Dr. Rosmarin reported the 52-week results at the 2022 annual meeting of the American Academy of Dermatology.
The trial group used 1.5% ruxolitinib cream twice daily for the full year. The vehicle group began using ruxolitinib halfway through the trial. In this group, 26.8% and 29.6% achieved F-VASI 75 at 52 weeks in the two trials.
For treating vitiligo, patients are advised to apply a thin layer of topical ruxolitinib to affected areas twice a day, “up to 10% body surface area,” according to the prescribing information, which adds: “Satisfactory patient response may require treatment … for more than 24 weeks. If the patient does not find the repigmentation meaningful by 24 weeks, the patient should be reevaluated by the health care provider.”
The most common side effects during the vehicle-controlled part of the trials were development of acne and pruritus at the application site, headache, urinary tract infections, erythema at the application site, and pyrexia, according to the company.
The approved label for topical ruxolitinib includes a boxed warning about serious infections, mortality, cancer, major adverse cardiovascular events, and thrombosis – which, the warning notes, is based on reports in patients treated with oral JAK inhibitors for inflammatory conditions.
Dr. Rosmarin believes that using this drug with other therapies, like light treatment, might yield even better responses. The available data are in patients treated with ruxolitinib as monotherapy, without complementary therapies.
William Damsky, MD, PhD, professor of dermatology and dermatopathology at Yale University, New Haven, who was not involved in the trials, said what is most exciting about this drug is its novelty. Although some topical steroids are used off-label to treat vitiligo, their efficacy is far from what’s been observed in these trials of topical ruxolitinib, he told this news organization. “It’s huge for a number of reasons. … One very big reason is it just provides some hope” for the many patients with vitiligo who, over the years, have been told “that there’s nothing that could be done for their disease, and this really changes that.”
Dr. Rosmarin reports financial relationships with over 20 pharmaceutical companies. Dr. Damsky disclosed no relevant financial relationships.

Methotrexate’s impact on COVID-19 vaccination: New insights made
Patients who take methotrexate for a variety of immune-mediated inflammatory diseases and pause taking the drug following receipt of a COVID-19 vaccine dose did not have a higher risk of disease flare and had higher antireceptor binding domain (anti-RBD) antibody titers and increased immunogenicity when compared with continuing the drug, three recent studies suggest.
In one study, British researchers examined the effects of a 2-week break in methotrexate therapy on anti-RBD titers following receipt of a third COVID-19 vaccine dose. In their paper published in The Lancet: Respiratory Medicine, they reported results from a randomized, open-label, superiority trial that suggested pausing the drug improved immunogenicity, compared with no break.
In two trials presented at the European Alliance of Associations for Rheumatology (EULAR) 2022 Congress, a team from India set out to determine whether holding methotrexate after receiving both doses of a COVID-19 vaccine, or holding it only after the second dose, was safe and effective. They found that pausing methotrexate only following the second dose contributed to a lower flare risk, and that patients had higher anti-RBD titers when holding methotrexate for 2 weeks following each dose.
Pausing methotrexate after booster
The 2-week methotrexate break and booster vaccine dose data in the Vaccine Response On Off Methotrexate (VROOM) trial showed that after a month, the geometric mean antispike 1 (S1)-RBD antibody titer was 10,798 U/mL (95% confidence interval [CI], 8,970-12,997) in the group that continued methotrexate and 22,750 U/mL (95% CI, 19,314-26,796) in the group that suspended methotrexate; the geometric mean ratio was 2.19 (P < .0001; mixed-effects model), reported Abhishek Abhishek, MD, PhD, professor of rheumatology at the University of Nottingham in Nottingham, England, and colleagues.
Prior research showed that stopping methotrexate therapy for 2 weeks following the seasonal influenza vaccine contributed to better vaccine immunity among patients with rheumatoid arthritis, but there was no impact of stopping the drug for up to 4 weeks before vaccination on vaccine-related immunity, the researchers noted.
It is crucial in maximizing long-lasting vaccine protection in people who are possibly susceptible through immune suppression at this point in the COVID-19 vaccination regimen, the study team noted.
“Evidence from this study will be useful for policymakers, national immunization advisory committees, and specialist societies formulating recommendations on the use of methotrexate around the time of COVID-19 vaccination. This evidence will help patients and clinicians make informed choices about the risks and benefits of interrupting methotrexate treatment around the time of COVID-19 vaccination, with implications for the potential to extend such approaches to other therapeutics,” they wrote.
In American College of Rheumatology (ACR) guidance for COVID-19 vaccination, the organization advised against using standard synthetic disease-modifying antirheumatic medicines such as methotrexate “for 1-2 weeks (as disease activity allows) after each COVID-19 vaccine dose,” given the at-risk population and public health concerns, Jeffrey A. Sparks, MD, MMSc, assistant professor of medicine and associate physician at Brigham and Women’s Hospital and Harvard Medical School, Boston, and Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School, noted in an accompanying editorial in The Lancet: Respiratory Medicine.
However, when the ACR developed this statement, there was only one trial involving patients with rheumatoid arthritis who paused methotrexate following seasonal influenza vaccination, the editorialists said.
“Although this finding adds to the evidence base to support interruption of methotrexate after vaccination, a shared decision process is needed to weigh the possible benefit of optimizing protection from COVID-19 and the possible risk of underlying disease flare,” they added.
Dr. Abhishek and colleagues assessed 254 patients with immune-mediated inflammatory disease from dermatology and rheumatology clinics across 26 hospitals in the United Kingdom. Participants had been diagnosed with systemic lupus erythematosus, rheumatoid arthritis, atopic dermatitis, polymyalgia rheumatica, axial spondyloarthritis, and psoriasis without or with arthritis. They had also been taking up to 25 mg of methotrexate per week for 3 months or longer and had received two doses of either the Pfizer/BioNTech BNT162b2 vaccine or AstraZeneca/Oxford viral vector vaccine. The booster dose was most often the Pfizer BNT162b2 vaccine (82%). The patients’ mean age was 59 years, with females comprising 61% of the cohort. Participants were randomly assigned 1:1 to either group.
Investigators performing laboratory analysis were masked to cohort assignment, and clinical research staff, data analysts, participants, and researchers were unmasked.
The elevated antibody response of patients who suspended methotrexate was the same across different kinds of immune-mediated inflammatory disease, primary vaccination platform, SARS-CoV-2 infection history, and age.
Notably, no intervention-associated adverse events were reported, the study team noted.
The conclusions that could be drawn from the booster-dose study were limited by the trial’s modest cohort size, the small number of patients in exploratory subgroup analyses, a lack of information about differences in prescription drug behavior, and early termination’s effect on the researchers’ ability to identify differences between subgroups and in secondary outcomes, the authors noted.
Other limitations included a lack of generalizability to patients with active disease who couldn’t stop therapy and were not included in the investigation, and participants were not blinded to what group they were in, the researchers said.
Expert commentary
This current study is consistent with other studies over the last several months showing that methotrexate harms both humoral and cell-mediated COVID-19 responses, noted Kevin Winthrop, MD, MPH, professor of infectious disease and public health at Oregon Health & Science University, Portland, who was not involved in the study. “And so now the new wave of studies are like this one, where they are holding methotrexate experimentally and seeing if it makes a difference,” he said.
“The one shortcoming of this study – and so far, the studies to date – is that no one has looked at whether the experimental hold has resulted in a change in T-cell responses, which ... we are [now] recognizing [the importance of] more and more in long-term protection, particularly in severe disease. Theoretically, holding [methotrexate] might help enhance T-cell responses, but that hasn’t been shown experimentally.”
Dr. Winthrop pointed out that one might get the same benefit from holding methotrexate for 1 week instead of 2 and that there likely is a reduced risk of flare-up from underlying autoimmune disease.
It is still not certain that this benefit extends to other vaccines, Dr. Winthrop noted. “It is probably true for most vaccines that if you hold methotrexate for 1 or 2 weeks, you might see some short-term benefit in responsiveness, but you don’t know that there is any clinical meaningfulness of this. That’s going to take other long-term studies. You don’t know how long this benefit lasts.”
Pausing methotrexate during initial COVID vaccine doses
Patients with either rheumatoid arthritis or psoriatic arthritis had higher anti-RBD antibody titers when methotrexate was stopped after both doses of the AstraZeneca vaccine, or simply after the second dose, than when methotrexate was continued, according to results from two single-center, randomized controlled trials called MIVAC I and II, Anu Sreekanth, MD, of Sree Sudheendra Medical Mission in Kochi, Kerala, India, and colleagues reported at EULAR 2022.
Results from MIVAC I indicated that there was a higher flare rate when methotrexate was stopped after both vaccine doses, but there was no difference in flare rate in MIVAC II when methotrexate was stopped only after the second dose as opposed to stopping it after both doses.
In the MIVAC I trial, 158 unvaccinated patients were randomized 1:1 to a cohort in which methotrexate was held for 2 weeks after both doses and a cohort in which methotrexate was continued despite the vaccine. In MIVAC II, 157 patients continued methotrexate while receiving the first vaccine dose. These patients were subsequently randomized either to continue or to stop methotrexate for 2 weeks following the second dose.
The findings from MIVAC I demonstrated the flare rate was lower in the methotrexate-continue group than in the methotrexate-pause group (8% vs. 25%; P = .005) and that the median anti-RBD titer was significantly higher for the methotrexate-pause group than the methotrexate-continue group (2,484 vs. 1,147; P = .001).
The results from MIVAC II trial indicated that there was no difference in flare rates between the two study groups (7.9% vs. 11.8%; P = .15). Yet, the median anti-RBD titer was significantly higher in the methotrexate-pause cohort than in the methotrexate-continue cohort (2,553 vs. 990; P = .001).
The report suggests there is a flare risk when methotrexate is stopped, Dr. Sreekanth noted. “It appears more logical to hold only after the second dose, as comparable anti-RBD titers are generated” with either approach, Dr. Sreekanth said.
Expert commentary: MIVAC I and II
Inés Colmegna, MD, associate professor at McGill University in Montreal, noted that it was intriguing that the risk of flares in MIVAC II is half of that reported after each of the doses of MIVAC I. “It is also worth emphasizing that despite the reported frequency of flares, the actual disease activity [as measured by the Disease Activity Score in 28 joints] in patients who did or did not withhold methotrexate was similar.
“MIVAC I and II have practical implications as they help to adequately inform patients about the risk and benefit trade of withholding methotrexate post–COVID-19 vaccination,” Dr. Colmegna told this news organization.
“Additional information would help to [further] interpret the findings of these studies, including whether any of the participants were taking any other DMARDs; data on the severity of the flares and functional impact; analysis of factors that predict the risk of flares, such as higher doses of methotrexate; [and change in] disease activity scores pre- and postvaccination,” Dr. Colmegna concluded.
Dr. Abhishek disclosed relationships with Springer, UpTodate, Oxford, Immunotec, AstraZeneca, Inflazome, NGM Biopharmaceuticals, Menarini Pharmaceuticals, and Cadila Pharmaceuticals. Dr. Abhishek is cochair of the ACR/EULAR CPPD Classification Criteria Working Group and the OMERACT CPPD Working Group. Dr. Sparks disclosed relationships with Gilead, Boehringer Ingelheim, Amgen, Bristol-Myers Squibb, and AbbVie, unrelated to this study. Dr. Tedeschi disclosed relationships with ModernaTx and NGM Biopharmaceuticals. Dr. Winthrop disclosed a research grant and serving as a scientific consultant for Pfizer.

In their paper published in The Lancet: Respiratory Medicine, they reported results from a randomized, open-label, superiority trial that suggested pausing the drug improved immunogenicity, compared with no break.
In two trials presented at the European Alliance of Associations for Rheumatology (EULAR) 2022 Congress, a team from India set out to determine whether holding methotrexate after receiving both doses of a COVID-19 vaccine, or holding it only after the second dose, was safe and effective. They found that pausing methotrexate only following the second dose contributed to a lower flare risk, and that patients had higher anti-RBD titers when holding methotrexate for 2 weeks following each dose.
Pausing methotrexate after booster
The 2-week methotrexate break and booster vaccine dose data in the Vaccine Response On Off Methotrexate (VROOM) trial showed that after a month, the geometric mean antispike 1 (S1)-RBD antibody titer was 10,798 U/mL (95% confidence interval [CI], 8,970-12,997) in the group that continued methotrexate and 22,750 U/mL (95% CI, 19,314-26,796) in the group that suspended methotrexate; the geometric mean ratio was 2.19 (P < .0001; mixed-effects model), reported Abhishek Abhishek, MD, PhD, professor of rheumatology at the University of Nottingham in Nottingham, England, and colleagues.
Prior research showed that stopping methotrexate therapy for 2 weeks following the seasonal influenza vaccine contributed to better vaccine immunity among patients with rheumatoid arthritis, but there was no impact of stopping the drug for up to 4 weeks before vaccination on vaccine-related immunity, the researchers noted.
It is crucial in maximizing long-lasting vaccine protection in people who are possibly susceptible through immune suppression at this point in the COVID-19 vaccination regimen, the study team noted.
“Evidence from this study will be useful for policymakers, national immunization advisory committees, and specialist societies formulating recommendations on the use of methotrexate around the time of COVID-19 vaccination. This evidence will help patients and clinicians make informed choices about the risks and benefits of interrupting methotrexate treatment around the time of COVID-19 vaccination, with implications for the potential to extend such approaches to other therapeutics,” they wrote.
In American College of Rheumatology (ACR) guidance for COVID-19 vaccination, the organization advised against using standard synthetic disease-modifying antirheumatic medicines such as methotrexate “for 1-2 weeks (as disease activity allows) after each COVID-19 vaccine dose,” given the at-risk population and public health concerns, Jeffrey A. Sparks, MD, MMSc, assistant professor of medicine and associate physician at Brigham and Women’s Hospital and Harvard Medical School, Boston, and Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School, noted in an accompanying editorial in The Lancet: Respiratory Medicine.
However, when the ACR developed this statement, there was only one trial involving patients with rheumatoid arthritis who paused methotrexate following seasonal influenza vaccination, the editorialists said.
“Although this finding adds to the evidence base to support interruption of methotrexate after vaccination, a shared decision process is needed to weigh the possible benefit of optimizing protection from COVID-19 and the possible risk of underlying disease flare,” they added.
Dr. Abhishek and colleagues assessed 254 patients with immune-mediated inflammatory disease from dermatology and rheumatology clinics across 26 hospitals in the United Kingdom. Participants had been diagnosed with systemic lupus erythematosus, rheumatoid arthritis, atopic dermatitis, polymyalgia rheumatica, axial spondyloarthritis, and psoriasis without or with arthritis. They had also been taking up to 25 mg of methotrexate per week for 3 months or longer and had received two doses of either the Pfizer/BioNTech BNT162b2 vaccine or AstraZeneca/Oxford viral vector vaccine. The booster dose was most often the Pfizer BNT162b2 vaccine (82%). The patients’ mean age was 59 years, with females comprising 61% of the cohort. Participants were randomly assigned 1:1 to either group.
Investigators performing laboratory analysis were masked to cohort assignment, and clinical research staff, data analysts, participants, and researchers were unmasked.
The elevated antibody response of patients who suspended methotrexate was the same across different kinds of immune-mediated inflammatory disease, primary vaccination platform, SARS-CoV-2 infection history, and age.
Notably, no intervention-associated adverse events were reported, the study team noted.
The conclusions that could be drawn from the booster-dose study were limited by the trial’s modest cohort size, the small number of patients in exploratory subgroup analyses, a lack of information about differences in prescription drug behavior, and early termination’s effect on the researchers’ ability to identify differences between subgroups and in secondary outcomes, the authors noted.
Other limitations included a lack of generalizability to patients with active disease who couldn’t stop therapy and were not included in the investigation, and participants were not blinded to what group they were in, the researchers said.
Expert commentary
This current study is consistent with other studies over the last several months showing that methotrexate harms both humoral and cell-mediated COVID-19 responses, noted Kevin Winthrop, MD, MPH, professor of infectious disease and public health at Oregon Health & Science University, Portland, who was not involved in the study. “And so now the new wave of studies are like this one, where they are holding methotrexate experimentally and seeing if it makes a difference,” he said.
“The one shortcoming of this study – and so far, the studies to date – is that no one has looked at whether the experimental hold has resulted in a change in T-cell responses, which ... we are [now] recognizing [the importance of] more and more in long-term protection, particularly in severe disease. Theoretically, holding [methotrexate] might help enhance T-cell responses, but that hasn’t been shown experimentally.”
Dr. Winthrop pointed out that one might get the same benefit from holding methotrexate for 1 week instead of 2 and that there likely is a reduced risk of flare-up from underlying autoimmune disease.
It is still not certain that this benefit extends to other vaccines, Dr. Winthrop noted. “It is probably true for most vaccines that if you hold methotrexate for 1 or 2 weeks, you might see some short-term benefit in responsiveness, but you don’t know that there is any clinical meaningfulness of this. That’s going to take other long-term studies. You don’t know how long this benefit lasts.”
Pausing methotrexate during initial COVID vaccine doses
Patients with either rheumatoid arthritis or psoriatic arthritis had higher anti-RBD antibody titers when methotrexate was stopped after both doses of the AstraZeneca vaccine, or simply after the second dose, than when methotrexate was continued, according to results from two single-center, randomized controlled trials called MIVAC I and II, Anu Sreekanth, MD, of Sree Sudheendra Medical Mission in Kochi, Kerala, India, and colleagues reported at EULAR 2022.
Results from MIVAC I indicated that there was a higher flare rate when methotrexate was stopped after both vaccine doses, but there was no difference in flare rate in MIVAC II when methotrexate was stopped only after the second dose as opposed to stopping it after both doses.
In the MIVAC I trial, 158 unvaccinated patients were randomized 1:1 to a cohort in which methotrexate was held for 2 weeks after both doses and a cohort in which methotrexate was continued despite the vaccine. In MIVAC II, 157 patients continued methotrexate while receiving the first vaccine dose. These patients were subsequently randomized either to continue or to stop methotrexate for 2 weeks following the second dose.
The findings from MIVAC I demonstrated the flare rate was lower in the methotrexate-continue group than in the methotrexate-pause group (8% vs. 25%; P = .005) and that the median anti-RBD titer was significantly higher for the methotrexate-pause group than the methotrexate-continue group (2,484 vs. 1,147; P = .001).
The results from MIVAC II trial indicated that there was no difference in flare rates between the two study groups (7.9% vs. 11.8%; P = .15). Yet, the median anti-RBD titer was significantly higher in the methotrexate-pause cohort than in the methotrexate-continue cohort (2,553 vs. 990; P = .001).
The report suggests there is a flare risk when methotrexate is stopped, Dr. Sreekanth noted. “It appears more logical to hold only after the second dose, as comparable anti-RBD titers are generated” with either approach, Dr. Sreekanth said.
Expert commentary: MIVAC I and II
Inés Colmegna, MD, associate professor at McGill University in Montreal, noted that it was intriguing that the risk of flares in MIVAC II is half of that reported after each of the doses of MIVAC I. “It is also worth emphasizing that despite the reported frequency of flares, the actual disease activity [as measured by the Disease Activity Score in 28 joints] in patients who did or did not withhold methotrexate was similar.
“MIVAC I and II have practical implications as they help to adequately inform patients about the risk and benefit trade of withholding methotrexate post–COVID-19 vaccination,” Dr. Colmegna told this news organization.
“Additional information would help to [further] interpret the findings of these studies, including whether any of the participants were taking any other DMARDs; data on the severity of the flares and functional impact; analysis of factors that predict the risk of flares, such as higher doses of methotrexate; [and change in] disease activity scores pre- and postvaccination,” Dr. Colmegna concluded.

Think of pediatric morphea as a systemic, chronic disease, expert advises
INDIANAPOLIS – In the opinion of Elena Pope, MD, MSc,
“There is no correlation between the extent and activity of skin lesions and the presence, severity, and activity of extracutaneous manifestations,” Dr. Pope, professor of pediatrics at the University of Toronto and division head of pediatric dermatology at the Hospital for Sick Children in Toronto, said during the annual meeting of the Society for Pediatric Dermatology. “Treatment needs to be tailored to the extent of cutaneous manifestations, and I think we need to be aware of and address the impact on patients’ quality of life,” she added. There is also a need for more research “on targeted and better-tolerated therapies to put a stop to the progression of disease.”
Congenital morphea is a form of localized scleroderma that presents at birth but can be confused with port wine stain. Results from a multicenter retrospective review of 25 cases conducted by Dr. Pope and colleagues found that the median age at diagnosis was 2.9 years and 76% had linear-type lesions. In addition, 48% had extracutaneous involvement (all of these patients had linear morphea), most commonly of the central nervous system.
“It’s important to realize these lesions may become active over time,” Dr. Pope said. “In my experience, there are two different courses. Either you have innocuous lesions when the patients are born and they may become active around 3-4 years of age, or you have early intrauterine involvement, with lesions inactive at birth but with potential for significant damage in utero.”
She cautioned against treating a suspected port wine stain lesion with laser until congenital morphea is ruled out. “I’m aware of at least one lawsuit of a child where someone used a laser in a child who had progression with significant sclerosis,” she said. “The parents assumed it was the use of the laser that led to the progression, not the actual disease.”
Extracutaneous manifestations are common in morphea patients. A multicenter study of 750 patients with juvenile scleroderma found that 22% had extracutaneous manifestations. Almost half of patients (47%) had arthritis, but 17% had neurologic findings such as seizures and headaches, 9% had vascular manifestations, and 8% had uveitis. Subsequent studies found that neurological disease affects between 11% and 19% of cases, especially in those involving the head and neck.
“There is a wide range of manifestations from headache and neuropsychiatric changes to brain atrophy, seizures, and CNS cavernoma,” Dr. Pope said. “There also can be orthodental involvement such as malocclusion. It’s important to do a brain MRI, eye exam for uveitis, and don’t forget the orthodental assessment.”
She recalled a 10-year-old boy who presented to the Hospital for Sick Children with tissue loss on the forehead and eyebrow and eyelashes. He had no other congenital morphea symptoms and the MRI was normal, but the eye exam revealed uveitis. “It’s important to remember that uveitis is asymptomatic, so unless you look for it, you’re not going to find it,” she said.
According to unpublished data in 42 congenital morphea patients with lesions limited to the head and neck, who underwent MRI imaging at the Hospital for Sick Children, 57% had CNS changes that were ipsilateral in 68% of cases. “White matter changes were the most common, and to our surprise, there were patients who had progressive CNS disease, including CNS vasculitis, new lesions, and enhancement of prior stable lesions,” Dr. Pope said.
She recalled the case of an 8-year-old boy who presented to the hospital with intractable seizures. Upon completion of the MRI, one of the radiologists noted that the imaging showed subtle thinning of the forehead, and he was referred to Dr. Pope and colleagues for assessment. In the span of 4 years, despite aggressive treatment, the boy’s CNS disease progressed. “There was more enhancement, more tissue loss, his seizures are very hard to control, and he has many neurodevelopmental changes,” she recalled. “What I learned from this case is that skin activity does not correlate with imaging. Don’t assume that just because the skin is burnt out that the CNS will be the same. Also, the extent of skin disease does not predict involvement or progression of the CNS.”
Linear lesions on the lower extremities are a harbinger of orthopedic complications, which can occur in about half of patients. Joint contractures in this subset of patients are seen in about 81% of cases, while other sequelae can include arthritis, limb atrophy, leg-leg discrepancy, and angular deformity. “About 14% of patients require intervention,” Dr. Pope said. “In terms of working those patients up, you need to do an MRI and assess the extent of muscle and fascial involvement. Early physiotherapy and an orthopedic evaluation are also recommended.”
As for possible markers of morphea, antinuclear antibody is positive in 22%-68% of cases and correlates with disease severity, extracutaneous manifestations, and disease flare-up. Antihistone antibodies (AHA) are positive in about 47% of cases, “and that tends to correlate with the extent of skin and muscle involvement,” Dr. Pope said. “Anti–double-stranded DNA correlates with extent of disease, but the only known biomarker to date that correlates with disease activity is CXCL9/10. This has been documented in the skin as well as in the blood. So, this marker may help us determine if the patient needs to be treated or not.”
Treatments
For treatment of active localized disease, topical medications are helpful in some cases. Options include topical steroids, calcipotriol with or without betamethasone, imiquimod, and tacrolimus. “In my experience the combination of calcipotriol with betamethasone is best,” she said. “It really shuts down the activity fairly soon, and you can scale down to calcipotriol alone. I don’t find imiquimod very helpful for active lesions, although it has a role for inactive lesions.”
For patients with linear or generalized/mixed disease, “the combination of methotrexate and corticosteroids or methotrexate alone is probably the way to go,” Dr. Pope said. “The addition of steroids really depends on where the lesion is and how worried you are about other problems.”
According to the best available literature, 88% of patients should respond to treatment with methotrexate (MTX) and/or steroids within 3-6 months, and 74% within 3 months. “If they don’t, you have to wonder if the patient’s taking the medication, or you need to think about other alternative treatments,” she said. “Complete remission is possible in most of the patients, and the longer you treat the more you will see that. On average, most of us treat patients for about 3 years, but there are treatment failures as well. This can occur in up to 16% of patients.”
As for second-line treatment agents for congenital morphea, clinicians often turn to mycophenolate mofetil (MMF). Results from a retrospective longitudinal study of juvenile localized scleroderma patients found that after a mean of 9 years 91% of patients on MMF and 100% of patients on MTX had inactive disease. “There were no differences in relapse rates, although MMF seems to have a more sustained long-term effect and overall is better tolerated,” said Dr. Pope, who was not involved with the study. “However, it’s more immunosuppressive than MTX, which is important, especially in the era of COVID-19. You also need to think about the potential for more hematological suppression with MMF use.” If standard therapy fails, there is anecdotal data supporting the use of abatacept (which suppresses the T-cell activity in affected patients), tofacitinib (which inhibits transforming growth factor–beta), or dupilumab (which inhibits interleukin-4).
Dr. Pope emphasized the effect congenital morphea has on quality of life. Remarks from patients with facial morphea and their parents who participated in a focus group on the topic organized by the Hospital for Sick Children included, “You just want to stay inside because you are afraid of what people will say,” “They laugh at her. They make fun of her, and it’s terrible,” and “MTX makes me feel weird. I would throw up, feel dizzy.”
“You have to take that into consideration, because we cannot make the treatment worse than the disease,” Dr. Pope said. “There are many domains where patients could be affected, including skin symptoms, physical functioning, body image and social support, side effects of medication, and presence of extracutaneous manifestations. Predictors of poor quality of life include female sex and involvement of hands and feet.”
Dr. Pope disclosed that she has received grants/research support from AbbVie, Centocor, and Amgen. She has also received consulting fees from AbbVie, Sanofi, Novartis, Boehringer-Ingelheim, Phoenix, Amryt Pharma, and Timber Pharmaceuticals.

Results from a retrospective longitudinal study of juvenile localized scleroderma patients found that after a mean of 9 years 91% of patients on MMF and 100% of patients on MTX had inactive disease. “There were no differences in relapse rates, although MMF seems to have a more sustained long-term effect and overall is better tolerated,” said Dr. Pope, who was not involved with the study. “However, it’s more immunosuppressive than MTX, which is important, especially in the era of COVID-19. You also need to think about the potential for more hematological suppression with MMF use.” If standard therapy fails, there is anecdotal data supporting the use of abatacept (which suppresses the T-cell activity in affected patients), tofacitinib (which inhibits transforming growth factor–beta), or dupilumab (which inhibits interleukin-4).
Dr. Pope emphasized the effect congenital morphea has on quality of life. Remarks from patients with facial morphea and their parents who participated in a focus group on the topic organized by the Hospital for Sick Children included, “You just want to stay inside because you are afraid of what people will say,” “They laugh at her. They make fun of her, and it’s terrible,” and “MTX makes me feel weird. I would throw up, feel dizzy.”
“You have to take that into consideration, because we cannot make the treatment worse than the disease,” Dr. Pope said. “There are many domains where patients could be affected, including skin symptoms, physical functioning, body image and social support, side effects of medication, and presence of extracutaneous manifestations. Predictors of poor quality of life include female sex and involvement of hands and feet.”
Dr. Pope disclosed that she has received grants/research support from AbbVie, Centocor, and Amgen. She has also received consulting fees from AbbVie, Sanofi, Novartis, Boehringer-Ingelheim, Phoenix, Amryt Pharma, and Timber Pharmaceuticals.

Neural networks can distinguish PsA from rheumatoid arthritis on MRI
Hand images are sufficient
NEW YORK – On the basis of MRI images of the hand, a neural network has been trained to distinguish seronegative and seropositive rheumatoid arthritis (RA) from psoriatic arthritis (PsA) as well as from each other, according to a study that was presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
In the work so far, the neural network was correct about 70% of the time in the absence of any further clinical analyses, according to David Simon, MD, a rheumatologist in the department of internal medicine at Friedrich-Alexander University, Erlangen, Germany.
Previous to this work, “there has been no study that has exclusively used hand MRI data and deep learning without requiring further expert input for the classification of arthritides,” Dr. Simon said.
In fact, when demographic and clinical data were added, there was no improvement in the performance of patient classification relative to the deep learning classification alone, according to the data presented by Dr. Simon.
The images were evaluated with residual neural networks (ResNet), which represents a sophisticated form of deep learning to facilitate the flow of information across the network layers as they form to improve accuracy in their ability to distinguish one form of disease from the other. The training was performed on images from the T1 coronal, T2 corona1, T1 coronal fat suppressed with contrast, T1 axial fat suppressed with contrast, and T2 fat suppressed axial sequences.
The study included hand MRI scans from 135 patients with seronegative RA, 190 with seropositive RA, 177 with PsA, and 147 with psoriasis. The performance was judged on the basis of area under the receiver operating characteristics curve (AUROC) with and without input of clinical characteristics. Patients who had psoriasis without clinical arthritis were included as a control population.
The AUROC for accuracy was 75% for seropositive RA relative to PsA, 74% for seronegative RA relative to PsA, and 67% for seropositive relative to seronegative RA. Of the patients who had psoriasis without arthritis, 98% were classified as PsA and 2% as RA.
Subsequent to the classification of the patients with psoriasis, 14 of the 147 (9.5%) have developed PsA so far over a relatively short follow-up. All of these were among those identified as PsA by neural network evaluation of the hand MRIs.
This suggests that “a PsA-like pattern may be present early in the course of psoriatic disease,” Dr. Simon said.
In the groups with joint disease, who had mean ages ranging from 56 to 65, the mean disease durations were 2.6 years for those with seropositive RA, 1.3 years for those with seronegative RA, and 0.8 years for those with PsA. The patients with psoriasis were younger (mean age, 40.5 years) but had a longer disease duration (mean 4.2 years).
All of the MRI sequences were relevant for classification, but contrast did not appear to help with accuracy.
“If the images with contrast enhancement were deleted, the loss of performance was only marginal,” Dr. Simon reported.
The accuracy of neural networks increases with data, making it likely that further refinements in methodology will lead to a greater degree of accuracy, according to Dr. Simon. While the methodology is not yet ready for routine use in the clinic, the study demonstrates that neural network analysis of hand MRI to distinguish forms of arthritis “is possible.” Further studies are planned toward the goal of creating a viable clinical tool.
“Of course, if we could create an accurate tool with ultrasound, this would be even more practical,” said Dr. Simon, recognizing the value of an office tool, but he cautioned that this would be far more challenging.
“The precision of MRI is an important factor for effective neural network training,” he said.
Utility: ‘In challenging cases if the accuracy improves’?
A viable method for objectively and rapidly distinguishing inflammatory joint diseases, particularly in patients with an ambiguous clinical presentation, is an unmet need, according to Philip J. Mease, MD, director of rheumatology research at Swedish Medical Center, Seattle.
Although the data presented are promising, Dr. Mease said in an interview that he believes there is a fair amount of work to be done before imaging analysis based on deep learning makes its way into routine clinical care. He is also hoping for methods to distinguish RA from PsA that are easier and less expensive, such as serum biomarkers. However, he agreed that a MRI-based tool could be useful when differentiating disease that is challenging.
“MRI is an expensive way for routine classification of disease, but this approach could be useful in challenging cases if the accuracy improves,” he said.
Meanwhile, other clinical researchers might want to test the principle. “You can try it,” said Dr. Simon, who reported that his team has made the methodology publicly available.
Dr. Simon reported no conflicts of interest. Dr. Mease reported financial relationships with more than 10 pharmaceutical companies, most of which make products used for the treatment of inflammatory joint diseases.
