Experts agree on routine lung disease screening in systemic sclerosis
MADRID – The for early detection, monitoring, and, when warranted, treatment, Anna-Maria Hoffmann-Vold, MD, PhD, reported at the European Congress of Rheumatology.
“Everyone with systemic sclerosis needs to be screened because this is the most important risk factor for ILD,” said Dr. Hoffmann-Vold, a clinical scientist in the division of rheumatology at the University of Oslo and head of scleroderma research at Oslo University Hospital.
Although the frequency of screening is not specified based on the opinion that this should be based on risk factors and other clinical characteristics, there was unanimous agreement that lung function tests do not represent an adequate screening tool or method for assessing ILD severity. Rather, the recommendations make clear that lung function studies are adjunctive to high-resolution computed tomography (HRCT).
“HRCT is the primary tool for evaluating ILD, but there was 100% agreement that assessment should include more than one measure, including lung function tests and clinical assessment,” Dr. Hoffmann-Vold reported.
There was a strong opinion that the numerous potential biomarkers described for ILD, although promising, are not yet ready for clinical use.
In developing these new recommendations, 95 potential statements were considered by the panel of 27 rheumatologists, pulmonologists, and others with experience in this field. A Delphi process was used for members of the panel to identify areas of agreement to produce consensus statements.
The result has been more than 50 statements issued in six major domains. These include statements on risk factors, appropriate methodology for diagnosis and severity assessment, when to initiate therapy, and when and how to initiate treatment escalation.
“We want to increase clinician awareness and provide standardized guidance for evaluating patients for the presence and medical management of ILD-SSc,” Dr. Hoffmann-Vold explained.
ILD occurs in about half of all patients with systemic sclerosis. Among these, approximately one out of three will experience lung disease progression. Although these high prevalence rates are well recognized and associated with high morbidity and mortality, Dr. Hoffmann-Vold said that there has been uncertainty about how to screen systemic sclerosis patients for ILD and what steps to take when it was found. It is this uncertainty that prompted the present initiative.
The consensus recommendations are an initial step to guide clinicians, but Dr. Hoffmann-Vold noted that the many statements are based on expert opinion, suggesting more studies are needed to compare strategies for objective severity grading and prediction of which patients are most at risk for ILD progression.
“There are still huge knowledge gaps we need to fill,” she stated. Still, she believes these recommendations represent progress in this field. While they are likely “to increase the standard of care” for those who develop ILD-SSc, they also have identified where to concentrate further research.
Dr. Hoffmann-Vold reported financial relationships with Actelion, Boehringer Ingelheim, and GlaxoSmithKline.

REPORTING FROM EULAR 2019 Congress
Checkpoint inhibitor–induced rheumatic complications have unique features
MADRID – The musculoskeletal complications of checkpoint inhibitors therapy are sometimes described as RA like, but a detailed analysis of a consecutive series of patients presented at the European Congress of Rheumatology produced the conclusion that the phenotypic expression is unique.
“These manifestations do not necessarily include synovial involvement, so their description as a rheumatoid arthritis–like presentation is not accurate. Rather, our findings suggest the pathology is something completely different and completely new,” said Alexandra Filippopoulou, MD, a rheumatology resident at the University of Patras (Greece).
This comment was based on a prospective study evaluating musculoskeletal complications in patients treated with checkpoint inhibitors over a recent 2-year period. Of the 130 consecutive patients who received a checkpoint inhibitor in the study period, 10 (7.7%) complained of joint pain and were determined to have an inflammatory complication.
The median time to development of musculoskeletal symptoms in this mostly male patient series was 2.5 months. The site of cancer was lung in four, bladder in three, kidney in two, and skin in one. Nivolumab (Opdivo) was the most common checkpoint inhibitor used, but others were represented.
MRI studies were conducted in 8 of the 10 patients. Overall, the MRI studies showed more myofascial than synovial involvement, but Dr. Filippopoulou described three distinct patterns.
In four patients, there was prominent periarticular involvement marked by diffuse swelling in the hands, feet, knees, or a combination of these joints. Synovitis, when observed, was mild, but myositis and fasciitis were common in adjacent tissues.
In three patients with a chief complaint of knee pain, myofasciitis was prominent in the surrounding muscles. Again, synovitis, when observed, was mild. It was unclear whether a partial tear of the quadriceps tendon observed in one patient was checkpoint inhibitor related.
In a third pattern, shared by three other patients, synovitis was prominent, but so was myositis in adjacent muscles. In two of these patients, the inflammatory activity was confined to the hands; in the third, both the knees and the ankle were also involved.
Regardless of these patterns of inflammation, “almost all of these patients continued to show good range of motion, which is not something that is commonly seen in patients with rheumatoid arthritis,” Dr. Filippopoulou observed.
Overall, the joint pain tended to be mild to moderate. They all responded well to low-dose glucocorticoids or analgesics without need to discontinue the anticancer therapy, Dr. Filippopoulou reported.
Not least interesting of the findings, 50% of the patients with musculoskeletal adverse events had a favorable response to the checkpoint inhibitor therapy, compared with just 12.5% of patients without these complaints, a difference that reached statistical significance (P = .0016), according to Dr. Filippopoulou. This observation is consistent with a study published last year that also associated immune-related adverse events with a greater likelihood of an anticancer response (Ann Rheumatic Dis. 2018;77:393-8).
“This is an interesting finding, but the theory that musculoskeletal adverse events predict a better response to checkpoint inhibitor therapy needs to be proven,” she said.
A larger case series is needed to better characterize joint inflammation associated with checkpoint inhibitors, but Dr. Filippopoulou concluded from her series that these adverse events are not accurately described as RA like. Rather, the phenotypic expression appears to be unique, not fully resembling any other joint pathology.
Dr. Filippopoulou reported no potential conflicts of interest.

REPORTING FROM EULAR 2019 CONGRESS
Systemic sclerosis gastrointestinal symptoms helped by gut microbiota transplant
MADRID – compared with control subjects in a 16-week randomized, double-blind, placebo-controlled pilot study presented at the European Congress of Rheumatology.
The effects were most pronounced on lower GI symptoms, including bloating, diarrhea, and fecal incontinence, with improvement reported by three of five of the patients given the gut microbiota transplant, compared with two of the five patients who received placebo.
“We were surprised by the effect the patients reported, as all had longstanding SSc with GI symptoms,” Anna-Maria Hoffmann-Vold, MD, PhD, of Oslo University Hospital, said in an interview ahead of the congress. “We were especially surprised at the strong effect FMT had on fecal incontinence.”“Patients with systemic sclerosis are very prone to having gastrointestinal involvement – up to 90% of patients have GI symptoms, and it’s associated with very high morbidity and mortality,” she observed during her presentation at the Congress. Despite that, there currently are no disease-modifying treatments that specifically addresses GI involvement in SSc.
It’s been known for a while that patients with SSc have a different intestinal microbiota composition, or dysbiosis, compared with healthy controls, and the possibility of permanent modification of the microbiome through fecal microbiota transplant (FMT) from healthy to ill individuals has become a subject of increased attention in the scientific literature in recent years,. Dr. Hoffmann-Vold said.
In particular, FMT has shown promising results in the treatment of Clostridium difficile infections. While the current study did not focus on mechanistic pathways by which FMT might be exerting its effects, such studies are definitely warranted, she said. “One could speculate that there is a mechanistic link between dysmotility and dysbiosis in SSc, and that the manipulation of gut microbiota with FMT primarily affects motility patterns, which in turn leads to improvement of GI symptoms.”
Together with colleagues at the Oslo University Hospital, Dr. Hoffmann-Vold randomly assigned 10 patients – all women – with limited cutaneous SSc either to treatment with a commercially-available gut microbiota preparation known as anaerobic cultivated human intestinal microbiota (ACHIM) or to placebo. Both ACHIM and placebo were given via gastroduodenoscopy. Their aim was to determine the safety of the approach, as well as to obtain preliminary data on its therapeutic potential.
The UCLA GIT 2.0 score questionnaire was used to assess GI symptoms, with patients defined as responders if they met the questionnaire’s definition of a minimally clinically important difference.
Primary endpoints were safety and clinical efficacy on GI symptoms assessed at weeks 4 and 16, and safety was assessed by observation, interviews, and a standardized safety form.
Results showed improvement in GI symptoms (total UCLA GIT score) in three of the five patients who received the gut microbiota transplant versus two of the five placebo-treated patients at 16 weeks. Two patients in the active treatment versus one in the placebo group had unchanged symptoms, and one patient in the placebo group had worsening symptoms.
Adverse events associated with treatment were “transient and mild”. However, one procedure-related serious adverse event occurred in a placebo-treated patient, which was a duodenal perforation.
Concluding her presentation, Dr. Hoffman-Vold said: “FMT of commercially-available ACHIM in patients with SSc appeared safe, had beneficial effects on lower GI symptoms, altered gut microbiota composition – richness and diversity – and appeared to affect the mucosal immune system.”
The research team has just received national funding for a larger randomized clinical trial that will involve 70 SSc patients and should start towards the end of the year.
The study was sponsored by Helse Sør-øst and NKS. Dr. Hoffmann-Vold has received research funding, consulting fees, or other remuneration from Boehringer Ingelheim, GlaxoSmithKline, and Actelion. A coauthor is the owner of the company that provided the gut microbiota.

EULAR issues guidelines on managing rheumatic complications of cancer immunotherapies
MADRID – EULAR has issued recommendations to help rheumatologists address the increasingly common clinical issue of diagnosing and managing rheumatic-related adverse events associated with cancer immunotherapy.
“The rheumatic adverse events associated with immunotherapy represent a spectrum of new clinical entities, and they are challenging because they can be difficult to control while attempting to preserve the antitumor effects of oncological drugs,” Marie Kostine, MD, of the Centre Universitaire Hospitalier, Bordeaux, France, explained at the European Congress of Rheumatology.
The recommendations were drawn from the deliberations of an expert task force that identified the clinical issues to address and then developed a consensus about best practice recommendations. In addition to rheumatologists with expertise in this field, the task force included oncologists, allied health personnel, and two patient representatives.
The recommendations include four overarching principles and 10 recommendations.
“One of the overarching principles regards the importance of shared decision making between rheumatologists, oncologists, and patients,” Dr. Kostine said. Because of the expertise of rheumatologists in employing immunomodulatory therapies as they pertain to inflammation of the joints, the recommendations emphasize the value of their collaboration in clinical decisions.
The recommendations address patient referral, the assessment of preexisting rheumatic conditions, diagnosis, and therapeutic strategies.
“Rheumatologists should make themselves aware of the wide spectrum of potential clinical presentations of rheumatic adverse events following the initiation of immunotherapy,” Dr. Kostine said. While rheumatoid arthritis–like symptoms are common, the immune activation produced by checkpoint inhibitors and other immunotherapies can affect nearly every organ in the body, which includes diverse involvement of joint tissues.
In addition to joint pain, which has occurred in up to 40% of patients receiving a checkpoint inhibitor in some series, rheumatology-related events can include vasculitis, systemic sclerosis, and lupus. When associated with immunotherapy, these events sometimes develop in the absence of inflammatory markers or autoantibodies.
The new consensus guidelines emphasize that glucocorticoids can be “considered” to control rheumatic-related adverse events despite their immunosuppressive effect. However, because of their potential to attenuate the benefit of immune activation for treatment of the oncologic disease, such drugs, if used, “should be tapered to the lowest effective dose.”
The consensus recommendations were based on an extensive literature review, but Dr. Kostine acknowledged that prospective studies regarding the best practices for managing rheumatic-related adverse events of immunotherapies remain limited. She suggested that this knowledge gap was one reason for creating an expert task force.
“There has been an immunotherapy revolution, such that rheumatologists who have not yet seen these adverse events soon will,” said Dr. Kostine, noting that the number of approved immunotherapies and their clinical indications have been increasing rapidly.
The EULAR recommendations were created specifically for rheumatologists. In addition to guiding them toward best practice, the report from the task force provides background on the clinical issues raised by therapies that cause inflammatory side effects while stimulating immune function to treat malignancy.

“One of the overarching principles regards the importance of shared decision making between rheumatologists, oncologists, and patients,” Dr. Kostine said. Because of the expertise of rheumatologists in employing immunomodulatory therapies as they pertain to inflammation of the joints, the recommendations emphasize the value of their collaboration in clinical decisions.
The recommendations address patient referral, the assessment of preexisting rheumatic conditions, diagnosis, and therapeutic strategies.
“Rheumatologists should make themselves aware of the wide spectrum of potential clinical presentations of rheumatic adverse events following the initiation of immunotherapy,” Dr. Kostine said. While rheumatoid arthritis–like symptoms are common, the immune activation produced by checkpoint inhibitors and other immunotherapies can affect nearly every organ in the body, which includes diverse involvement of joint tissues.
In addition to joint pain, which has occurred in up to 40% of patients receiving a checkpoint inhibitor in some series, rheumatology-related events can include vasculitis, systemic sclerosis, and lupus. When associated with immunotherapy, these events sometimes develop in the absence of inflammatory markers or autoantibodies.
The new consensus guidelines emphasize that glucocorticoids can be “considered” to control rheumatic-related adverse events despite their immunosuppressive effect. However, because of their potential to attenuate the benefit of immune activation for treatment of the oncologic disease, such drugs, if used, “should be tapered to the lowest effective dose.”
The consensus recommendations were based on an extensive literature review, but Dr. Kostine acknowledged that prospective studies regarding the best practices for managing rheumatic-related adverse events of immunotherapies remain limited. She suggested that this knowledge gap was one reason for creating an expert task force.
“There has been an immunotherapy revolution, such that rheumatologists who have not yet seen these adverse events soon will,” said Dr. Kostine, noting that the number of approved immunotherapies and their clinical indications have been increasing rapidly.
The EULAR recommendations were created specifically for rheumatologists. In addition to guiding them toward best practice, the report from the task force provides background on the clinical issues raised by therapies that cause inflammatory side effects while stimulating immune function to treat malignancy.
MADRID – EULAR has issued recommendations to help rheumatologists address the increasingly common clinical issue of diagnosing and managing rheumatic-related adverse events associated with cancer immunotherapy.
“The rheumatic adverse events associated with immunotherapy represent a spectrum of new clinical entities, and they are challenging because they can be difficult to control while attempting to preserve the antitumor effects of oncological drugs,” Marie Kostine, MD, of the Centre Universitaire Hospitalier, Bordeaux, France, explained at the European Congress of Rheumatology.
The recommendations were drawn from the deliberations of an expert task force that identified the clinical issues to address and then developed a consensus about best practice recommendations. In addition to rheumatologists with expertise in this field, the task force included oncologists, allied health personnel, and two patient representatives.

REPORTING FROM EULAR 2019 CONGRESS
Antibody hierarchy may drive development of SLE vs. antiphospholipid syndrome
according to study findings presented at the European Congress of Rheumatology.
Spanish researchers found that the number of antiphospholipid (aPL) antibodies present was important for the development of antiphospholipid syndrome (APS) and that lupus anticoagulant (LA) was the major aPL antibody linked to systemic lupus erythematosus (SLE)–related organ involvement.
“aPL [antibodies] has been extensively associated with an increased risk of thrombosis and poor pregnancy outcomes, mainly in patients with primary APS,” study investigator Leyre Riancho-Zarrabeitia, MD, PhD, explained in an interview ahead of the congress.
“Moreover, aPL [antibody] positivity in SLE has been proposed to be associated with higher damage accrual and with certain manifestations such as valvular heart disease, pulmonary hypertension, and neuropsychiatric manifestations,” she added.
Anticardiolipin antibodies – notably IgG rather than IgM isotypes – also seemed to play an important role in APS and SLE manifestations, Dr. Riancho-Zarrabeitia, of Hospital Sierrallana, Instituto De Investigación Marqués De Valdecilla, and the University of Cantabria (Spain), noted during her oral presentation.
She reported data on 3,651 patients included in the RELESSER registry between October 2011 and August 2012. This large, multicenter, hospital-based registry retrospectively collects immunologic, clinical and demographic data from unselected adult patients with SLE who are attending 45 Spanish rheumatology services within the country’s national health system.
Over one-third (37.5%) of patients, who had a mean age of 47 years and were mostly (90%) women, were positive for aPL. The most frequent aPL detected was IgG anticardiolipin (aCL) antibodies, seen in 25% of patients, followed by LA in 24%, and IgM aCL in 20%.
Of the aPL-positive patients, 20.6% were positive for only one antibody, 12.1% were positive for two antibodies, and 4.8% were positive for three antibodies.
“All types of aPL were associated with classic APS manifestations,” Dr. Riancho-Zarrabeitia said. The associations were strongest for thrombotic events, such as arterial and venous small-vessel thrombosis and recurrent early pregnancy losses.
aCL antibodies conferred the highest risk for arterial thrombosis, she noted (odds ratio, 5.7), whereas LA conferred the highest risk for venous thrombosis (OR, 4.7). Both IgG and IgM isotypes were associated with thrombotic events, fetal death and recurrent pregnancy loss, but the association was stronger with the IgG isotypes.
Having more than one aPL was particularly associated with a higher risk of these APS manifestations. For example, when one antibody was present the OR for arterial thrombosis was 4.45, but when two or more aPL were detected, the ORs rose to 9.23 and 15.6, respectively.
aCL and LA also were associated with thrombocytopenia and hemolytic anemia, with ORs of around 1-2 and 2-3 respectively. There also were antibody associations with cognitive impairments.
Similar results were seen in patients with SLE. “aPL [antibody] positivity in SLE patients influenced the risk for thrombotic and obstetric manifestations,” Dr. Riancho-Zarrabeitia said. LA and aCL were associated with an increased risk of neuropsychiatric manifestations, and LA was linked to an increased risk for renal disease.
The risk for specific SLE manifestations was again higher with IgG isotypes of aCL, notably an increased risk for cardiac and respiratory events.
While increased antibody numbers generally led to a higher risk of complications, the risk for cutaneous manifestations decreased.
“The load of aPL [antibodies] confers a higher risk for APS,” Dr. Riancho-Zarrabeitia said during her conclusion. “Regarding systemic lupus erythematosus, the number of positive antibodies is directly associated with neurological and ophthalmological manifestations, and inversely associated with cutaneous manifestations.”
What these findings show, said Dr. Riancho-Zarrabeitia in the precongress interview, is that individuals who test positive for aPL antibodies need careful monitoring to prevent and treat severe manifestations. “The next step would be to confirm our findings with a prospective study.”

REPORTING FROM EULAR 2019 CONGRESS
Pap screen gaps abound in SLE population
SAN FRANCISCO – Ann Igoe, MD, said at an international congress on systemic lupus erythematosus.
Why is this of relevance to rheumatologists?
“The rheumatologist is probably the main physician that lupus patients see. They may see their rheumatologist every couple of months. The question is, how often do rheumatologists say, ‘Hey, you need your Pap smear!’ I don’t think many of them address it,” said Dr. Igoe, a rheumatology fellow at Case Western Reserve University in Cleveland.
She presented a retrospective, cross-sectional, single-center study utilizing the EHRs of 604 women with SLE and 3,337 female controls who had asthma but not SLE. Sixty percent of the SLE patients were overdue for a Pap smear, compared with 51% of controls.
“We also looked at race,” Dr. Igoe said in an interview. “We were able to show that, at our institution, racial disparities do exist, that the black lupus patients had a much higher rate of HPV [human papillomavirus] positivity, compared to the white lupus patients, and they also were more behind on their Pap screening.”
Indeed, 56% of the black lupus patients were overdue for a Pap test, compared with 43% of the white SLE patients, and 46% of black women without SLE. Among the subgroup composed of black HPV-positive SLE patients, the overdue status rate soared to 70%, versus 30% in white HPV-positive SLE patients.
Dr. Igoe noted that in October 2018, the Food and Drug Administration approved an expanded indication for the quadrivalent HPV vaccine known as Gardasil 9 for women through 45 years of age. The prior upper age limit was age 26. This is an especially important development for unvaccinated women with SLE. Women with SLE have been shown to have higher rates of cervical neoplasia than in the general population, and being on potent immunosuppressive agents such as mycophenolate mofetil, azathioprine, and methotrexate further boosts that risk.
“We and others have shown that women with lupus who receive the vaccine mount a good response. So regardless of whether you’ve had HPV in the past, that doesn’t preclude you from getting the vaccine,” she noted.
The Advisory Committee on Immunization Practices and Centers for Disease Control and Prevention have yet to adopt the expanded age limit recommendation. That needs to happen, Dr. Igoe stressed.
“I’d like to see this study as a little stepping stone towards having women get their Pap screen addressed and making the Gardasil vaccine available to women who are not vaccinated,” she said.
She reported having no financial conflicts regarding her study, conducted free of commercial support.

Cumulative smoking affects skin manifestations of SLE
SAN FRANCISCO – Nnenna Ezeh reported at an international congress on systemic lupus erythematosus.
“We saw in our study a suggestion of a dose-response relationship. If we tell patients, ‘The more you smoke, the more likely you are to have chronic skin disease or skin damage that’s permanent,’ it could be a way to trigger more smoking cessation strategies in their mind,” said Ms. Ezeh, of the University of Wisconsin, Madison. “We know that skin manifestations of lupus have a major negative impact on a patient’s quality of life, so this could be a way to decrease smoking by saying, ‘Not only does smoking impact your heart and put you at risk for cardiovascular disease, it also affects your skin.’ It’s a way to bridge the priorities that physicians have with the priorities that patients have.”
She presented a retrospective study of the medical records of 632 consecutive SLE patients seen at the university medical center’s ambulatory rheumatology clinic. Slightly more than 60% of them were never smokers; 8.7% had a history of low smoking exposure, defined as less than 5 pack-years; 5.8% had a medium-smoking history of 5-10 pack-years; 15% had a high-smoking history, with more than 10 pack-years; and the smoking history of 10% of the patients was unrecorded.
In a multivariate analysis adjusted for age, sex, and race, the low-smoking group was ninefold more likely than never smokers to develop any mucocutaneous manifestations of SLE, including a malar or discoid rash, mucosal ulcers, photosensitivity, alopecia, or scarring. They were also 3.7 times more likely to meet any Systemic Lupus International Collaborating Clinics (SLICC) cutaneous criteria and twofold more likely than never smokers to meet any of the American College of Rheumatology cutaneous criteria. Patients with an intermediate smoking exposure history of 5-10 pack-years were 2.3-fold more likely to meet any SLICC cutaneous criteria.
The risks of meeting SLICC chronic cutaneous criteria and SLICC Damage Index skin damage criteria rose in a linear fashion with the number of pack-years of smoking. Those SLE patients with more than a 10 pack-year smoking history were 4.2-fold more likely than never smokers to fulfill any SLICC Damage Index skin damage criteria, which consist of scarring alopecia, extensive scarring, or skin ulcers. The heaviest smokers were also at 2.1-fold increased risk of discoid lupus and 2.2-fold more likely to meet SLICC chronic cutaneous criteria, according to Ms. Ezeh.
Patients of color, who comprised 18% of the study population, were significantly more likely to smoke than white patients. Independent of their smoking history, however, they had significantly increased risks of chronic cutaneous manifestations of lupus and of irreversible skin damage.
Ms. Ezeh reported having no financial conflicts regarding her study, supported by a grant from the Rheumatology Research Foundation.

Patients of color, who comprised 18% of the study population, were significantly more likely to smoke than white patients. Independent of their smoking history, however, they had significantly increased risks of chronic cutaneous manifestations of lupus and of irreversible skin damage.
Ms. Ezeh reported having no financial conflicts regarding her study, supported by a grant from the Rheumatology Research Foundation.

Rituximab serious infection risk predicted by immunoglobulin levels
Monitoring immunoglobulin (Ig) levels at baseline and before each cycle of rituximab could reduce the risk of serious infection events (SIEs) in patients needing repeated treatment, according to research published in Arthritis & Rheumatology.
In a large, single-center, longitudinal study conducted at a tertiary referral center, having low IgG (less than 6 g/L) in particular was associated with a higher rate of SIEs, compared with having normal IgG levels (6-16 g/L). Considering 103 of 700 patients who had low levels of IgG before starting treatment with rituximab for various rheumatic and musculoskeletal diseases (RMDs), there were 16.4 SIEs per 100 patient-years. In those who developed low IgG during subsequent cycles of rituximab therapy, the SIE rate was even higher, at 21.3 per 100 patient-years. By comparison, the SIE rate for those with normal IgG levels was 9.7 per 100 patient-years.
“We really have to monitor immunoglobulins at baseline and also before we re-treat the patients, because higher IgG level is protective of serious infections,” study first author Md Yuzaiful Md Yusof, MBChB, PhD, said in an interview.
Low IgG has been linked to a higher risk of SIEs in the first 12 months of rituximab therapy but, until now, there have been limited data on infection predictors during repeated cycles of treatment. While IgG is a consistent marker of SIEs associated with repeated rituximab treatment, IgM and IgA should also be monitored to give a full picture of any hyperglobulinemia that may be present.
“There is no formal guidance on how to safely monitor patients on rituximab,” observed Dr. Md Yusof, who will present these data at the 2019 European Congress of Rheumatology in Madrid. The study’s findings could help to change that, however, as they offer a practical way to help predict and thus prevent SIEs. The study’s findings not only validate previous work, he noted, but also add new insights into why some patients treated with repeat rituximab cycles but not others may experience a higher rate of such infections.
Altogether, the investigators examined data on 700 patients with RMDs treated with rituximab who were consecutively seen during 2012-2017 at Dr. Md Yusof’s institution – the Leeds (England) Institute of Rheumatic and Musculoskeletal Medicine, which is part of the University of Leeds. Their immunoglobulin levels had been measured before starting rituximab therapy and every 4-6 months after each cycle of rituximab treatment.
Patients with any RMD being treated with at least one cycle of rituximab were eligible for inclusion in the retrospective study, with the majority (72%) taking it for rheumatoid arthritis and some for systemic lupus erythematosus (13%) or antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (7%).
One of the main aims of the study was to look for predictors of SIEs during the first 12 months and during repeated cycles of rituximab. Dr. Md Yusof and his associates also looked at how secondary hypogammaglobulinemia might affect SIE rates and the humoral response to vaccination challenge and its persistence following treatment discontinuation. Their ultimate aim was to see if these findings could then be used to develop a treatment algorithm for rituximab administration in RMDs.
Over a follow-up period encompassing 2,880 patient-years of treatment, 281 SIEs were recorded in 176 patients, giving a rate of 9.8 infections per 100 patient-years. Most (61%) of these were due to lower respiratory tract infections.
The proportion of patients experiencing their first SIE increased with time: 16% within 6 weeks of starting rituximab therapy, 35% at 12 weeks, 72% at 26 weeks, 83% at 38 weeks, and 100% by 1 year of repeated treatment.
Multivariable analysis showed that the presence of several comorbidities at baseline – notably chronic obstructive pulmonary disease, diabetes, heart failure, and prior cancer – raised the risk for SIEs with repeated rituximab therapy. The biggest factor, however, was a history of SIEs – with a sixfold increased risk of further serious infection.
Higher corticosteroid dose and factors specific to rituximab – low IgG, neutropenia, high IgM, and a longer time to retreatment – were also predictive of SIEs.
“Low IgG also results in poor humoral response to vaccination,” Dr. Md Yusof said, noting that the IgG level remains below the lower limit of normal for several years after rituximab is discontinued in most patients.
In the study, 5 of 8 (64%) patients had impaired humoral response to pneumococcal and haemophilus following vaccination challenge and 4 of 11 patients had IgG normalized after switching to another biologic disease-modifying antirheumatic drug (bDMARD).
Cyclophosphamide is commonly used as a first-line agent to induce remission in patients with severe and refractory systemic lupus erythematosus and ANCA-associated vasculitis, with patients switched to rituximab at relapse. The effect of this prior treatment was examined in 20 patients in the study, with a marked decline in almost all immunoglobulin classes seen up to 18 months. Prior treatment with immunosuppressants such as intravenous cyclophosphamide could be behind progressive reductions in Ig levels seen with repeated rituximab treatment rather than entirely because of rituximab, Dr. Md Yusof said.
Dr. Md Yusof, who is a National Institute for Health Research (NIHR) Academic Clinical Lecturer at the University of Leeds, said the value of the study, compared with others, is that hospital data for all patients treated with rituximab with at least 3 months follow-up were included, making it an almost complete data set.
“By carefully reviewing records of every patient to capture all infection episodes in the largest single-center cohort study to date, our findings provide insights on predictors of SIEs as well as a foundation for safety monitoring of rituximab,” he and his coauthors wrote.
They acknowledge reporting a higher rate of SIEs than seen in registry and clinical studies with rituximab, which may reflect a “channeling bias” as the patients comprised those with multiple comorbidities including those that represent a relative contraindication for bDMARD use. That said, the findings clearly show that Ig levels should be monitored before and after each rituximab cycle, especially in those with comorbid diseases and those with low IgG levels to start with.
They conclude that an “individualized benefit-risk assessment” is needed to determine whether rituximab should be repeated in those with low IgG as this is a “consistent predictor” of SIE and may “increase infection profiles when [rituximab] is switched to different bDMARDs.”
The research was supported by Octapharma, the National Institute for Health Research (NIHR), and NIHR Leeds Biomedical Research Centre based at Leeds Teaching Hospitals NHS Trust in England. Dr. Md Yusof had no conflicts of interest. Several coauthors disclosed financial ties to multiple pharmaceutical companies, including Roche.

Check for complementopathies in lupus pregnancy
SAN FRANCISCO – It’s important to check for complementopathies in pregnant women with lupus, according to Michelle Petri, MD, a professor of rheumatology at Johns Hopkins University, Baltimore.
A new diagnosis being developed at Hopkins and elsewhere, complementopathies involve an inappropriate activation of the alternative pathway of complement (APC), either from a mutation in a complement control protein, or, in the case of lupus, an autoantibody against one. They’ve been implicated as a major cause of hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, a condition to which women with lupus are particularly prone.
Hopkins has developed a serum test to diagnose inappropriate APC activation in a few hours, the modified Ham test. When HELLP develops in a woman with a complementopathy, the complement inhibitor eculizumab (Soliris) is proving to be a safe alternative to pregnancy termination.
“I urge you to think about using the modified Ham test, because if it is positive, you can treat HELLP without having to stop the pregnancy,” said Dr. Petri, also codirector of the Hopkins Lupus Pregnancy Center.
Lupus management has come a long way from the days when women were counseled to avoid or terminate pregnancy. Risks remain, “but many pregnancies are successful. I think that for every woman with lupus, we do want to offer the possibility of successful pregnancy,” she said.
Disease control is key. Preterm birth, the most common adverse outcome in lupus, correlates closely with disease activity, and disease activity can be controlled with hydroxychloroquine, and, when needed, azathioprine and tacrolimus for renal flairs.
“But these kinds of basic lessons – we need hydroxychloroquine in pregnancy; we must control disease activity – are not heard out in the real world. Claims data have shown that pregnant women with lupus actually take fewer prescribed medications, and they have fewer rheumatology visits.” It’s a problem that needs to be addressed, Dr. Petri said.
Vitamin D is also important. Hopkins has shown that supplementation to hit a level of 40 ng/mL reduces both global and renal disease activity without toxicity; studies in the general population have shown reduced preeclampsia, preterm birth, and low birth weight, all concerns in lupus.
“I haven’t convinced the world of lupus how important vitamin D is,” but “I actually love it just as much as I love hydroxychloroquine,” Dr. Petri said.
Cosupplementation with calcium complicates matters. Together, they seem to reduce the risk of preeclampsia, but increase the risk of preterm birth. More needs to be known, so “for all of us with pregnancy cohorts, it’s time to start to record vitamin D and calcium levels so we can look at this,” she said.
Dr. Petri has worked with numerous companies.

EXPERT ANALYSIS FROM LUPUS 2019
Warfarin found to increase adverse outcomes among patients with IPF
DALLAS – Warfarin appears to increase the risk of lung transplant or death for patients with fibrotic lung disease who need anticoagulation therapy, Christopher King, MD, said at the American Thoracic Society’s international conference.
Compared with direct oral anticoagulation (DOAC), warfarin doubled the risk of those outcomes, even after the researchers controlled for multiple morbidities that accompany the need for anticoagulation, said Dr. King, medical director of the transplant and advanced lung disease critical care program at Inova Fairfax (Va.) Hospital.
“The need for anticoagulation in patients with interstitial lung disease is already associated with an increased risk of death or transplant,” he said. Warfarin – but not oral anticoagulation – seems to increase that risk even more “no matter how you analyze it,” he said.
“We know now that fibrosis and coagulation are entwined, and there’s background epidemiologic data showing an increased incidence of venous thromboembolism and acute coronary syndrome in patients with pulmonary fibrosis. This suggests that a dysregulated coagulation cascade may play a role in the pathogenesis of fibrosis.”
The relationship has been explored for the last decade or so. Two recent meta-analyses came to similar conclusions.
In 2013, a 125-patient retrospective cohort study compared clinical characteristics and survival among patients with idiopathic pulmonary fibrosis (IPF) who received anticoagulant therapy with those who did not (Sarcoidosis Vasc Diffuse Lung Dis. 2013 Aug 1;30[2]:121-7). Those who got the treatment had worse survival outcomes at 1 and 3 years than did those who received no therapy (84% vs. 53% and 89% vs. 64%, respectively).
In 2016, a post hoc analysis of three placebo-controlled studies determined that any anticoagulant use independently increased the risk of death among patients with IPF, compared with nonuse: 15.6% vs 6.3% all-cause mortality (Eur Respir J. 2016. doi: 10.1183/13993003.02087-2015).
But these investigations didn’t parse out the types of anticoagulation. Direct oral anticoagulation (DOAC) is much more common now, however, and Dr. King and colleagues wanted to find out how warfarin and DOAC compared.
They retrospectively analyzed data from the Pulmonary Fibrosis Foundation’s database and compared the risk of lung transplant and death for patients on anticoagulation or no anticoagulation and for those receiving DOACs versus warfarin versus no anticoagulation.
The study comprised 1,918 patients, 91% of whom were not on anticoagulation therapy. The remaining 164 were either taking DOAC (n = 83) or warfarin (n = 81). Both of these groups were significantly older than those not on anticoagulation (70 vs. 67 years). As expected , they were significantly more likely to have cardiac arrhythmias, heart failure, or pulmonary embolism or deep vein thrombosis and significantly more likely to be on immunosuppressant therapy or steroids. Their diffusing capacity of lung for carbon dioxide was also significantly lower.
There were no significant lung disease–related differences in anticoagulation therapy, other than a trend toward more use among those with connective tissue disease–associated interstitial lung disease.
Over 2 years, the entire cohort experienced 110 deaths (5.7%), 52 transplants (2.7%), and 29 withdrawals (1.5%). Among patients with IPF, there were 80 deaths (6.7%), 43 transplants (3.6%) and 20 withdrawals (1.7%).
In an unadjusted analysis, anticoagulation more than doubled the risk of an event, compared with no anticoagulation (hazard ratio, 2.4). This was slightly attenuated, but still significant, in a multivariate model that controlled for age, gender, oxygen use, gastroesophageal reflux disease, obstructive sleep apnea, arrhythmia, cancer, heart failure, obesity, venous thromboembolism, and antifibrotics (HR, 1.88).
A second whole-cohort analysis looked at the survival ratios for both warfarin and DOAC, compared with no treatment. In the fully adjusted model, warfarin was associated with a significantly increased risk HR (2.28) but DOAC was not.
The investigators then examined risk in only patients with lung disease. Among those with IPF, the fully adjusted model showed that warfarin nearly tripled the risk of transplant or death (HR, 2.8), while DOAC had no significant effect.
The reason for this association remains unclear, Dr. King said. “Renal failure may be a big reason patients get warfarin instead of DOAC. It’s difficult to say whether these patients were frail or prone to bleeding. Even something like the care team not being as up to date with treatment could be affecting the numbers. And is it the direct effect of warfarin on fibrotic lung disease? Or maybe DOAC has some beneficial effect on pulmonary fibrosis? We don’t know.
“But what we can take away from this is that warfarin is associated with worse outcomes than DOAC in patients with IPF. It seems reasonable to use DOAC over warfarin if there’s no specific contraindication to DOAC. If you have a patient with pulmonary thrombosis who has indications for anticoagulation I would use DOAC, based on the evidence that we now have available.”

DALLAS – Warfarin appears to increase the risk of lung transplant or death for patients with fibrotic lung disease who need anticoagulation therapy, Christopher King, MD, said at the American Thoracic Society’s international conference.
Compared with direct oral anticoagulation (DOAC), warfarin doubled the risk of those outcomes, even after the researchers controlled for multiple morbidities that accompany the need for anticoagulation, said Dr. King, medical director of the transplant and advanced lung disease critical care program at Inova Fairfax (Va.) Hospital.
“The need for anticoagulation in patients with interstitial lung disease is already associated with an increased risk of death or transplant,” he said. Warfarin – but not oral anticoagulation – seems to increase that risk even more “no matter how you analyze it,” he said.
“We know now that fibrosis and coagulation are entwined, and there’s background epidemiologic data showing an increased incidence of venous thromboembolism and acute coronary syndrome in patients with pulmonary fibrosis. This suggests that a dysregulated coagulation cascade may play a role in the pathogenesis of fibrosis.”
The relationship has been explored for the last decade or so. Two recent meta-analyses came to similar conclusions.
In 2013, a 125-patient retrospective cohort study compared clinical characteristics and survival among patients with idiopathic pulmonary fibrosis (IPF) who received anticoagulant therapy with those who did not (Sarcoidosis Vasc Diffuse Lung Dis. 2013 Aug 1;30[2]:121-7). Those who got the treatment had worse survival outcomes at 1 and 3 years than did those who received no therapy (84% vs. 53% and 89% vs. 64%, respectively).
In 2016, a post hoc analysis of three placebo-controlled studies determined that any anticoagulant use independently increased the risk of death among patients with IPF, compared with nonuse: 15.6% vs 6.3% all-cause mortality (Eur Respir J. 2016. doi: 10.1183/13993003.02087-2015).
But these investigations didn’t parse out the types of anticoagulation. Direct oral anticoagulation (DOAC) is much more common now, however, and Dr. King and colleagues wanted to find out how warfarin and DOAC compared.
They retrospectively analyzed data from the Pulmonary Fibrosis Foundation’s database and compared the risk of lung transplant and death for patients on anticoagulation or no anticoagulation and for those receiving DOACs versus warfarin versus no anticoagulation.
The study comprised 1,918 patients, 91% of whom were not on anticoagulation therapy. The remaining 164 were either taking DOAC (n = 83) or warfarin (n = 81). Both of these groups were significantly older than those not on anticoagulation (70 vs. 67 years). As expected , they were significantly more likely to have cardiac arrhythmias, heart failure, or pulmonary embolism or deep vein thrombosis and significantly more likely to be on immunosuppressant therapy or steroids. Their diffusing capacity of lung for carbon dioxide was also significantly lower.
There were no significant lung disease–related differences in anticoagulation therapy, other than a trend toward more use among those with connective tissue disease–associated interstitial lung disease.
Over 2 years, the entire cohort experienced 110 deaths (5.7%), 52 transplants (2.7%), and 29 withdrawals (1.5%). Among patients with IPF, there were 80 deaths (6.7%), 43 transplants (3.6%) and 20 withdrawals (1.7%).
