Dental Health: What It Means in Kidney Disease
Q) I teach nephrology at a local PA program, and they want us to integrate dental care into each module. What’s the connection between the two?
Dental health is frequently overlooked in the medical realm, as many clinicians feel that dental issues are out of our purview. Hematuria worries us, but bleeding gums and other signs of periodontal disease are often ignored. Surprisingly, many patients don’t seem to mind when their gums bleed every time they brush; they believe that this is normal, when really, it’s not.
Growing evidence supports associations between dental health and multiple medical issues—chronic kidney disease (CKD) among them. Periodontal disease is one of several inflammatory diseases caused by an interaction between gram-negative periodontal bacterial species and the immune system. It manifests with sore, red, bleeding gums and can lead to tooth loss if left untreated.
Chronic inflammation in the gums is a good indicator of inflammation elsewhere in the body. In and of itself, periodontitis can set off an inflammatory cascade in the body. Poor dentition can also lead to poor nutrition, which then causes a feedback loop, leading to even more inflammation.
Patients with periodontal disease have higher levels of C-reactive protein and a higher erythrocyte sedimentation rate than those without the disease.1 And a recent study by Zhang et al showed that periodontal disease increased risk for all-cause mortality in patients with CKD.2
The high cost of CKD from both a financial and personal view makes any intervention worth exploring, as the risk factors are difficult to modify and the CKD population is growing worldwide. We, as medical providers, should reiterate what our dental colleagues have been saying for years: Encourage patients with CKD to practice good dental hygiene by brushing twice a day and flossing daily, in an attempt to improve their overall outcomes.

FDA: No more codeine or hydrocodone cold medicines for children
New safety labeling changes for prescription cough and cold medicines containing codeine or hydrocodone limit their use to adults 18 years or older.
The Food and Drug Administration took this action after “conducting an extensive review and convening a panel of outside experts,” which determined that the risks of these medicines outweigh their benefits in children younger than 18 years. The agency also is requiring companies to add a boxed warning to drug labels for prescription cough and cold medicines containing codeine or hydrocodone about the “risks of misuse, abuse, addiction, overdose, death, and slowed or difficult breathing,” according to an FDA safety announcement.
Common side effects of opioids include drowsiness, dizziness, nausea, vomiting, constipation, shortness of breath, and headache, according to the press release.
Reassure parents that cough because of a cold or upper respiratory infection is self-limited and generally does not need to be treated, the FDA advised. If children do need cough treatment, there are over-the-counter products such as dextromethorphan, as well as prescription benzonatate products, the FDA said. Encourage parents to check labels of nonprescription cough and cold products.
In a few states, some codeine cough medicines are available OTC. The FDA is considering regulatory action for these products, according to the safety announcement.

AUDIO: Immunotherapy’s role in NHL
ATLANTA – The use of immune checkpoint blockade is increasingly becoming standard therapy in Hodgkin lymphoma, but this approach has so far garnered mixed results in non-Hodgkin lymphoma, Stephen Ansell, MD, PhD, said at the annual meeting of the American Society of Hematology.
In an interview, Dr. Ansell, professor of medicine and chair of the lymphoma group at the Mayo Clinic, Rochester, Minn., said responses have been variable with promising results from immune checkpoint inhibitors in primary mediastinal large B-cell lymphoma, some NK/T-cell lymphomas, and primary CNS lymphoma. However, responses have been modest in low-grade lymphoma.
Dr. Ansell, who chaired a session at ASH 2017 on immunotherapy’s expanding role in non-Hodgkin lymphoma, said one of the major challenges of using immune checkpoint blockade in non-Hodgkin lymphoma is the complicated biology. For example, there are a lot of regulatory T cells that actually inhibit the immune response, and many of the T cells that are present within the tumor have an exhausted phenotype and are poorly functioning. Additionally, some of the cytokines that would seem to be stimulating the immune system can, over time, slowly produce T-cell exhaustion.
“Sort of like too much of a good thing ends up being a bad thing,” he said.
These are the issues that are fueling research today, Dr. Ansell said. Going forward he said he expects to see more combination approaches to therapy, such as using an agonistic positive signal plus the blocking of an inhibitory signal with chemotherapy.
Dr. Ansell reported that Mayo Clinic receives clinical trial support from Merck, Bristol-Myers Squibb, Seattle Genetics, Trillium, and Affimed.

EXPERT ANALYSIS FROM ASH 2017
Novel herpes zoster vaccine is more cost effective than old vaccine
The novel herpes zoster subunit vaccine (HZ/su) is more effective and less expensive than the currently used live attenuated virus (ZVL), according to a study from the Center for Value-Based Research.
Phuc Le, PhD, of the Cleveland Clinic and her colleague Michael Rothberg, MD, conducted an economic analysis of vaccine strategies from the societal perspective. This included the direct medical costs and productivity losses associated with HZ disease and complications.
The one-, two-, and three-way sensitivity analyses examined how different variables affected the cost-effectiveness of different vaccine strategies. The one-way analysis examined the association of input variables and cost-effectiveness. This included HZ/su prices, waning rate and initial efficacy of a dose of HZ/su, and the adherence rate. This analysis revealed that, compared with no vaccination, HZ/su would provide cost savings up to a price of $160, or $80 per dose.
Regardless of circumstance, HZ/su was always more effective than ZVL according to the two-way sensitivity analysis. This analysis took into account the joint effect of price, adherence to two doses of HZ/su, efficacy, and the waning rate of one dose and two doses of HZ/su and ZVL. Compared with ZVL, HZ/su would be less costly up to a price of $350 per series.
Adherence rates to vaccination schedules were important in determining the efficacy and waning rate which ultimately effected cost-effectiveness. The three-way sensitivity analysis found that, if HZ/su adherence to the second dose was greater than 56.8%, results were insensitive to the variation of single-dose efficacy and waning rate of HZ/su. But if adherence rates fell below 40%, combinations of waning rate and lower efficacy made HZ/su cost ineffective. Most importantly, ZVL was never cost effective for 60-year-old patients.
Despite a projected price of $280 per series, HZ/su is still more effective and less expensive than ZVL for adults 60 years or older. According to Dr. Le and Dr. Rothberg, the assumptions about the vaccine’s efficacy duration and price were reasonable. But, if the vaccine price were to rise in the future, or a single dose becomes much less effective than reported by GlaxoSmithKline, or if adherence to the second dose was remarkably low, the results of the study would be changed.
“An ACIP recommendation stating a preference for HZ/su over ZVL could lead to future price increases, which would render the vaccine no longer cost effective” wrote Dr. Le and Dr. Rothberg. “Therefore, a recommendation linked to periodic reassessment of cost-effectiveness based on the vaccine price might help to mitigate the effect of the recommendation on vaccine affordability.”
Dr. Le and Dr. Rothberg reported having no conflicts of interest.
The HZ/su vaccine is not yet approved by the U.S. Food and Drug Administration, but in 2017, the FDA Advisory Committee unanimously voted in favor of its use in adults age 50 years and older.

The herpes zoster (HZ) virus disproportionately affects elderly populations. As the U.S. population ages, tools and mechanisms to reduce the clinical and economic burden of HZ will be needed in the coming years.
The work of Dr. Le and Dr. Rothberg presents the results of an economic evaluation on randomized clinical trials of a yet-to-be-approved novel HZ subunit vaccine (HZ/su) to determine the economic and clinical benefit of the new vaccine, compared with the currently used vaccine. Although HZ/su is intended to be a two-dose vaccine, the study focused on a one-time vaccine strategy because booster vaccines are unpopular and not recommended by the Advisory Committee on Immunization Practices.
“If priced at $280 per two required doses, HZ/su appears to be a cost-saving option, compared with ZVL and a cost-effective option, compared with no-vaccine strategies,” wrote Dr. Najafzadeh. “However, the value of HZ/su vaccine would be even higher if it could be marketed at a price comparable to that of ZVL.” An added benefit of the HZ/su vaccine is that it can be used in immunocompromised patients.

Phase 1 study: Human IL-10 plus checkpoint blockade looks promising in RCC, NSCLC
NATIONAL HARBOR, MD. – Pegylated human interleukin-10 in combination with anti–PD-1 therapy is well tolerated and shows promise for the treatment of both renal cell carcinoma and non–small cell lung cancer, according to findings from a phase 1 study.
The IL-10 product, AM0010 (pegilodecakin), was shown to be well tolerated as monotherapy, and was evaluated in combination with anti–PD-1 therapy in the two expansion cohorts included in the current analysis, Martin Oft, MD, said at the annual meeting of the Society for Immunotherapy of Cancer.
Of 34 evaluable renal cell carcinoma (RCC) patients included in one expansion cohort, 15 (44%) had an objective response at a median follow-up of 27 months, and two of those had a complete response (CR), Dr. Oft of ARMO BioSciences, Redwood City, Calif. reported.
In contrast, only 4 of 16 evaluable patients who received AM0010 monotherapy (25%) had an objective response, he said.
In eight patients who received AM0010 + pembrolizumab (Keytruda), the objective response rate was 50%, and both patients who had a complete response were in that group. The median progression-free survival (PFS) was 16.7 months. In 26 who received AM0010 + nivolumab (Opdivo), 11 had an objective response, but neither the complete response nor PFS rates had been reached in patients in that group, he noted.
The responses were durable.
“In fact, we had one patient who stopped treatment after a year in [complete remission] and is now 1 year in total remission without any further treatment,” he said.
Patients with non–small cell lung cancer (NSCLC) also experienced some benefit from the combination therapy. Objective responses were observed in 11 of 27 evaluable NSCLC patients (41%) who were treated with AM0010 and an anti–PD-1(9 of 22 [41%] who received AM0010 and nivolumab, and 2 of 5 [40%] who received AM0010 and pembrolizumab).
Progression-free survival was not reached in this cohort.
An analysis by PD-L1 status showed that 33% of NSCLC patients with PD-L1 levels less than 1% achieved a response, 67% of those with PD-L1 levels of 1%-49% achieved a response, and 80% of those with PD-L1 levels of 50% or greater achieved a response, he said, adding that the responses were very durable in all three groups.
Of note, NSCLC patients with liver metastasis have been shown in prior trials to have a lower overall response rate to immune checkpoint inhibition, but in this trial, 7 of 9 patients with NSCLC metastasis to the liver had a partial response (PR), Dr. Oft said.
The RCC and NSCLC patients had a median of 1 and 2 prior therapies, respectively.
AM0010 was given subcutaneously at a dose of 10 or 20 mcg/kg daily, pembrolizumab was given intravenously at 2mg/kg every 3 weeks, and nivolumab was given intravenously at a dose of 3 mg/kg every 2 weeks.
Treatment-related adverse events included anemia, thrombocytopenia, and fatigue, and all were reversible and transient, Dr. Oft said, noting that grade 3 or 4 adverse events were mostly absent in patients receiving the lower dose; thus the recommended phase 2 dose is 10 mcg/kg.
“It’s important to note that three of those six patients [receiving the lower dose] in fact had a PR or CR so this lower dose did not come at the expense of efficacy,” he added.
The mechanistic rationale for combining AM0010 and anti-PD1 for the treatment of cancer patients lies in the fact that IL‐10 has anti‐inflammatory functions and stimulates the cytotoxicity and proliferation of antigen-activated CD8+ T cells. T cell receptor–mediated activation of CD8+ T cells elevates IL‐10 receptors and PD‐1, Dr. Oft explained.
The robust efficacy data and the observed CD8+ T cell activation seen in these expansion cohorts is promising and encourages the continued study of AM0010 in combination with PD-1 inhibition, he concluded, noting that larger studies are planned for the coming year.
Dr. Oft is a founder and employee of ARMO BioSciences, which sponsored this study.

The IL-10 product, AM0010 (pegilodecakin), was shown to be well tolerated as monotherapy, and was evaluated in combination with anti–PD-1 therapy in the two expansion cohorts included in the current analysis, Martin Oft, MD, said at the annual meeting of the Society for Immunotherapy of Cancer.
Of 34 evaluable renal cell carcinoma (RCC) patients included in one expansion cohort, 15 (44%) had an objective response at a median follow-up of 27 months, and two of those had a complete response (CR), Dr. Oft of ARMO BioSciences, Redwood City, Calif. reported.
In contrast, only 4 of 16 evaluable patients who received AM0010 monotherapy (25%) had an objective response, he said.
In eight patients who received AM0010 + pembrolizumab (Keytruda), the objective response rate was 50%, and both patients who had a complete response were in that group. The median progression-free survival (PFS) was 16.7 months. In 26 who received AM0010 + nivolumab (Opdivo), 11 had an objective response, but neither the complete response nor PFS rates had been reached in patients in that group, he noted.
The responses were durable.
“In fact, we had one patient who stopped treatment after a year in [complete remission] and is now 1 year in total remission without any further treatment,” he said.
Patients with non–small cell lung cancer (NSCLC) also experienced some benefit from the combination therapy. Objective responses were observed in 11 of 27 evaluable NSCLC patients (41%) who were treated with AM0010 and an anti–PD-1(9 of 22 [41%] who received AM0010 and nivolumab, and 2 of 5 [40%] who received AM0010 and pembrolizumab).
Progression-free survival was not reached in this cohort.
An analysis by PD-L1 status showed that 33% of NSCLC patients with PD-L1 levels less than 1% achieved a response, 67% of those with PD-L1 levels of 1%-49% achieved a response, and 80% of those with PD-L1 levels of 50% or greater achieved a response, he said, adding that the responses were very durable in all three groups.
Of note, NSCLC patients with liver metastasis have been shown in prior trials to have a lower overall response rate to immune checkpoint inhibition, but in this trial, 7 of 9 patients with NSCLC metastasis to the liver had a partial response (PR), Dr. Oft said.
The RCC and NSCLC patients had a median of 1 and 2 prior therapies, respectively.
AM0010 was given subcutaneously at a dose of 10 or 20 mcg/kg daily, pembrolizumab was given intravenously at 2mg/kg every 3 weeks, and nivolumab was given intravenously at a dose of 3 mg/kg every 2 weeks.
Treatment-related adverse events included anemia, thrombocytopenia, and fatigue, and all were reversible and transient, Dr. Oft said, noting that grade 3 or 4 adverse events were mostly absent in patients receiving the lower dose; thus the recommended phase 2 dose is 10 mcg/kg.
“It’s important to note that three of those six patients [receiving the lower dose] in fact had a PR or CR so this lower dose did not come at the expense of efficacy,” he added.
The mechanistic rationale for combining AM0010 and anti-PD1 for the treatment of cancer patients lies in the fact that IL‐10 has anti‐inflammatory functions and stimulates the cytotoxicity and proliferation of antigen-activated CD8+ T cells. T cell receptor–mediated activation of CD8+ T cells elevates IL‐10 receptors and PD‐1, Dr. Oft explained.
The robust efficacy data and the observed CD8+ T cell activation seen in these expansion cohorts is promising and encourages the continued study of AM0010 in combination with PD-1 inhibition, he concluded, noting that larger studies are planned for the coming year.

Office visits have a chronic problem
according to the National Center for Health Statistics.
That year, chronic problems were the major reason for 40% of all office-based physician visits, making them significantly more common than the other four broad categories of visit types: new problem (26%), preventive care (19%), injury (9%), and pre- or postsurgery care (6%), the NCHS said in a recent Data Brief.
Children were significantly more likely to have a new problem (41% of visits) or get preventive care (32%) than were the other age groups and were significantly less likely to have a chronic problem (18%) or to receive pre- or postsurgery care (2%), according to data from the 2014 National Ambulatory Medical Care Survey, which included 45,710 visit records from 9,989 physicians.

Waiving Medicare coinsurance for positive colorectal screening likely beneficial
Currently, Medicare covers colorectal screening at no charge to the patient, but if a polyp is removed upon discovery during the procedure, the patient would then be subject to Medicare’s coinsurance payments for both the colonoscopy and the removal.
Researchers used the Microsimulation Screening Analysis–Colon model to estimate the cost-effectiveness of waiving coinsurance for every component of colorectal cancer screening. They estimated that, currently, using the colonoscopy regimen with coinsurance, 12.8 colorectal cancer deaths occurred per 1,000 people aged 65 years and 124.1 QALYs were gained per 1,000 people aged 65 years. The total number of procedures per 1,000 Medicare beneficiaries was 1,132, of which 410 (36%) were potentially subject to coinsurance requirements.
“We estimated that the total lifetime costs for [the Centers for Medicare & Medicaid], which included colorectal cancer screening, surveillance, and treatment with coinsurance, to be $2.675 million per 1,000 65-year-olds,” Ms. Peterse and her colleagues wrote.
Researchers noted that if the coinsurance was waived but there was no follow-on increase in the screening rate, the benefits of screening would not change but the total cost of screening and treatment would increase to $2.726 million per 1,000 people aged 65 years.
However, “an assumed 5-percentage-point increase in the rates of first colonoscopy screening and surveillance decreased the number of colorectal cancer deaths by 0.9 (6.4%), accompanied by an increase of $33,000 (1.2%) in total costs, with a cost per QALY gained (or cost-effectiveness ratio) of $4,086.”
They added that estimated screening benefits were similar when fecal testing was the primary screening method.
“In general, [fecal testing] screening was associated with lower number of procedures subject to coinsurance,” the researchers added. “If [fecal testing] screening becomes more popular in the United States, following trends observed in several settings, the costs of waiving coinsurance would be even lower.” The researchers also suggest that it could lead to reducing disparities of colorectal cancer in the United States as well.

Nonmalignant Cutaneous Findings Associated With Vemurafenib
To the Editor:
A 53-year-old woman was referred by her oncologist to our dermatology office with lesions on the face and body that presented 8 days after starting vemurafenib 960 mg twice daily for metastatic melanoma. The patient denied any symptoms from the lesions but was concerned they would spread to cover her entire face and body.
The patient's medical history included a diagnosis of metastatic melanoma 6 years prior to presentation. She stated that the primary cutaneous melanoma site was unknown. The patient had endured numerous surgeries to excise lymph node tumors, with some lesions up to 3 cm. The patient recently started vemurafenib, a treatment for BRAF V600E mutation-positive metastatic melanoma. The patient's personal history was notable for hepatitis A, B, and C, and her family history revealed her mother had metastatic lung cancer.
Physical examination revealed numerous 2- to 3-mm, round-oval, flesh-colored to light-brown papules on the cheeks, chest, abdomen (Figure 1), back, and both arms and legs. Some papules were inflamed and some had a stuck-on appearance. Lesions on the chest between the breasts and inframammary region were slightly inflamed. Two skin biopsies were performed. Biopsy of the lesion on the right lateral back revealed solar lentigo, early macular seborrheic keratosis, and a focus of inflamed mild solar keratosis. The dermis showed a mild superficial perivascular and interstitial inflammatory infiltrate composed mostly of lymphocytes, histiocytes, and eosinophils. There were occasional melanophages present (Figure 2). Biopsy of the lesion between the breasts revealed inflamed verrucous seborrheic keratosis (Figure 3).
We treated the lesion on the right lateral back with cycles of cryotherapy and explained to the patient that the lesion between the breasts was benign. We also reiterated to the patient the importance of wearing sun-protective clothing and UVA/UVB sunblock with a sun protection factor of 30 or higher.
Our patient was diagnosed with pneumonia and subsequently had to discontinue vemurafenib. During the period of nontreatment, the keratotic lesions cleared with postinflammatory hyperpigmentation and no epidermal changes, which showed a possible inference of a direct relationship between the vemurafenib and the appearance of the nonmalignant cutaneous lesions. Although this report only represents 1 patient, other patients possibly can benefit from a modified dose of vemurafenib, which either would resolve or lessen the quantity of these lesions.
Vemurafenib is the first US Food and Drug Administration-approved treatment for nonresectable metastatic melanoma with the BRAF V600E mutation as detected by a US Food and Drug Administration-approved test.1,2 Mutated BRAF is present in approximately 60% of cutaneous melanomas.3 Vemurafenib targets the oncogenic BRAF V600E making the protein inactive, thus inhibiting cell proliferation and leading to apoptosis and shrinkage of the metastatic tumors.3-5 Vemurafenib has a response rate of more than 50% and is associated with rapid improvement in quality of life.3
Cutaneous side effects include increased incidence of squamous cell carcinoma and keratoacanthomas, appearing approximately 7 to 8 weeks after starting vemurafenib.4 The incidence of these lesions increases in patients 65 years and older and in patients with prior skin cancer and chronic sun exposure. The paradoxical activation of the mitogen-activated protein kinase pathway by mutant BRAF-selective inhibitors provides an explanation of the induction of squamous cell carcinomas.4 Prior to the initiation of vemurafenib, all patients should receive a total-body skin examination and every 2 months thereafter while on treatment. After discontinuation of the medicine, the patient should continue to receive total-body skin evaluations every 6 months indefinitely.
Patients should be aware of the potential for mild to severe photosensitivity reactions. They should be advised to limit their sun exposure time and to wear sun-protective clothing when outdoors. The use of broad-spectrum UVA/UVB sunscreen and lip protectant with a sun protection factor of 30 or higher also should be stressed.6,7 Patients should be aware that UVA rays penetrate glass; therefore, UV-protective clothing should be worn throughout the day and during all seasons.7
In clinical trials of vemurafenib, Stevens-Johnson syndrome and toxic epidermal necrolysis was reported in 2 patients.8,9 Clinical trials also reported patients developing new primary malignant melanoma lesions.10 These findings further emphasize the need for patients to undergo total-body skin examinations during and after treatment.
Other possible dermatologic reactions include a generalized rash, erythema, alopecia, and pruritus.2,3 The development of benign growths associated with patients on vemurafenib include follicular plugging seen in keratosis pilaris, palmar and plantar hyperkeratosis, seborrheic dermatitis-like rashes, verrucous keratosis, and acantholytic dyskeratosis.8,11,12
We report a case of nonmalignant growths occurring 8 days after starting vemurafenib. This case illustrates potential cutaneous adverse reactions that were benign yet still of great concern to our patient. Many of these nonmalignant cutaneous findings are associated with abnormal follicular keratinization thought to be secondary to abnormal signaling of the mitogen-activated protein kinase pathway that occurs with the use of BRAF inhibitors.8 Although in this case malignant lesions were not discovered, the need for total-body skin examinations exists during all stages of treatment. Supportive care and reassurance should be given to patients along with local treatments including topical therapies (steroids, retinoids), cryotherapy, and biopsies or excisions when necessary.13,14

There were occasional melanophages present (Figure 2). Biopsy of the lesion between the breasts revealed inflamed verrucous seborrheic keratosis (Figure 3).
We treated the lesion on the right lateral back with cycles of cryotherapy and explained to the patient that the lesion between the breasts was benign. We also reiterated to the patient the importance of wearing sun-protective clothing and UVA/UVB sunblock with a sun protection factor of 30 or higher.
Our patient was diagnosed with pneumonia and subsequently had to discontinue vemurafenib. During the period of nontreatment, the keratotic lesions cleared with postinflammatory hyperpigmentation and no epidermal changes, which showed a possible inference of a direct relationship between the vemurafenib and the appearance of the nonmalignant cutaneous lesions. Although this report only represents 1 patient, other patients possibly can benefit from a modified dose of vemurafenib, which either would resolve or lessen the quantity of these lesions.
Vemurafenib is the first US Food and Drug Administration-approved treatment for nonresectable metastatic melanoma with the BRAF V600E mutation as detected by a US Food and Drug Administration-approved test.1,2 Mutated BRAF is present in approximately 60% of cutaneous melanomas.3 Vemurafenib targets the oncogenic BRAF V600E making the protein inactive, thus inhibiting cell proliferation and leading to apoptosis and shrinkage of the metastatic tumors.3-5 Vemurafenib has a response rate of more than 50% and is associated with rapid improvement in quality of life.3
Cutaneous side effects include increased incidence of squamous cell carcinoma and keratoacanthomas, appearing approximately 7 to 8 weeks after starting vemurafenib.4 The incidence of these lesions increases in patients 65 years and older and in patients with prior skin cancer and chronic sun exposure. The paradoxical activation of the mitogen-activated protein kinase pathway by mutant BRAF-selective inhibitors provides an explanation of the induction of squamous cell carcinomas.4 Prior to the initiation of vemurafenib, all patients should receive a total-body skin examination and every 2 months thereafter while on treatment. After discontinuation of the medicine, the patient should continue to receive total-body skin evaluations every 6 months indefinitely.
Patients should be aware of the potential for mild to severe photosensitivity reactions. They should be advised to limit their sun exposure time and to wear sun-protective clothing when outdoors. The use of broad-spectrum UVA/UVB sunscreen and lip protectant with a sun protection factor of 30 or higher also should be stressed.6,7 Patients should be aware that UVA rays penetrate glass; therefore, UV-protective clothing should be worn throughout the day and during all seasons.7
In clinical trials of vemurafenib, Stevens-Johnson syndrome and toxic epidermal necrolysis was reported in 2 patients.8,9 Clinical trials also reported patients developing new primary malignant melanoma lesions.10 These findings further emphasize the need for patients to undergo total-body skin examinations during and after treatment.
Other possible dermatologic reactions include a generalized rash, erythema, alopecia, and pruritus.2,3 The development of benign growths associated with patients on vemurafenib include follicular plugging seen in keratosis pilaris, palmar and plantar hyperkeratosis, seborrheic dermatitis-like rashes, verrucous keratosis, and acantholytic dyskeratosis.8,11,12
We report a case of nonmalignant growths occurring 8 days after starting vemurafenib. This case illustrates potential cutaneous adverse reactions that were benign yet still of great concern to our patient. Many of these nonmalignant cutaneous findings are associated with abnormal follicular keratinization thought to be secondary to abnormal signaling of the mitogen-activated protein kinase pathway that occurs with the use of BRAF inhibitors.8 Although in this case malignant lesions were not discovered, the need for total-body skin examinations exists during all stages of treatment. Supportive care and reassurance should be given to patients along with local treatments including topical therapies (steroids, retinoids), cryotherapy, and biopsies or excisions when necessary.13,14

Practice Points
- Prior to starting a BRAF inhibitor, clinicians should perform a baseline total-body skin examination and follow-up every 2 months.
- Take photographs of the patient's entire body on initial total-body skin examination.
- Encourage sun protection for exposed areas on the body in all seasons.
VcR-CVAD yields high responses, ‘excellent’ survival in MCL
Adding rituximab and bortezomib to a moderate-intensity chemotherapy regimen and following it up with maintenance rituximab produced high response rates and “excellent” survival outcomes for adults with previously untreated mantle cell lymphoma (MCL), investigators reported in long-term follow-up of a small study.
The objective response rate (ORR) among 30 patients with MCL treated with VcR-CVAD – bortezomib (Velcade), rituximab, and hyperCVAD (hyper-fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone) followed by rituximab maintenance – was 90%, including a high proportion of complete responses (CR) or unconfirmed complete responses.
After a median follow-up of 7.8 years, the rates of 6-year progression-free and overall survival (PFS and OS) were 53% and 70%, respectively, with patients older and younger than 60 years having equally good outcomes, according to Julie E. Chang, MD, of the Wisconsin Institute of Medical Research in Madison, and her colleagues.
VcR-CVAD is a moderate-intensity regimen with a favorable toxicity profile that allowed tolerability even in an older population, the investigators noted. “An important lesson illustrated by VcR-CVAD is that long-term remissions are achievable in some patients without intensive inductions or consolidation,” they wrote in Clinical Lymphoma, Myeloma & Leukemia.
The investigators previously reported that after a median follow-up of 42 months, the 3-year PFS and OS were 63% and 86%, respectively, and that these outcomes were comparable to those reported with more intensive regimens (Br J Haematol. 2011 Oct;155[2]:190-7).
As noted, the ORR was 90%, including 77% CR/unconfirmed CR, 6-year PFS was 53%, and 6-year OS was 70%.
A univariate analysis showed a significant interaction between lactate dehydrogenase levels and age for PFS, and a trend, albeit not significant, toward an interaction with LDH levels and age for OS.
In multivariate analysis, worse Eastern Cooperative Oncology Group (ECOG) performance status at baseline showed a nonsignificant trend toward worse OS. In contrast, an increase of one in the number of extranodal disease sites was associated with better OS (relative risk 0.66, 95% confidence interval 0.01-0.66).
The investigators noted that the advent of new agents with activity against MCL and the use of prognostic information, such as minimal residual disease measurements, could help clinicians develop induction and maintenance strategies with better efficacy and lower toxicity than VcR-CVAD.
The study was supported by the National Institutes of Health, Millennium Pharmaceuticals, and the University of Wisconsin Forward Lymphoma Research Fund. Dr. Chang reported research funding from Genentech. One coauthor disclosed consulting work for Genentech and Millennium and research funding from Genentech.

High levels of neuroinflammatory markers may drive increased Alzheimer’s prevalence among blacks
Potent proinflammatory markers appear to be significantly elevated in the brains of black patients with Alzheimer’s disease, compared to the brains of white patients, while cytokines with a potentially neuroprotective role are decreased, a Food and Drug Administration researcher reported Jan. 11 at an agency grand rounds presentation
These differences may be driven by the NLRP3 gene, which, in the presence of neuronal insults like beta amyloid aggregates, can direct microglia to pump out a stew of inflammatory cytokines and chemokines, Dr. Ferguson said.
“This proposed pathway may help explain why black patients are twice as likely as white ones to develop AD, said Dr. Ferguson, acting director of FDA Division of Neurotoxicology. “Once NLRP3 is activated, it leads to chronically increased levels of inflammatory cytokines. Once they are chronically increased, it could lead to increased synaptic dysfunction, cognitive impairment, and cell death.”
Dr. Ferguson and her colleague, Vijayalakshmi Varma, PhD, FDA research biologist, obtained brain tissue samples from 12 black patients with AD and 12 white ones. She did not have baseline severity staging for the cohort, but said that the patients were a mean of 81 years old, and had confirmed AD pathology at the time of death.
The researchers examined neurodegenerative proteins and cytokine levels in the BA21 area of the brain. Located in the temporal lobe, BA21 is important in language and auditory processing. It generally exhibits atrophy and the characteristic AD lesions of beta amyloid plaques and tau tangles early in the disease.
In a previously published report of this neuropathological cohort, the team examined a number of markers of neurodegeneration including S100B, the soluble form of the receptor for advanced glycation end-products (sRAGE); glial cell-derived neurotrophic factor (GDNF); and amyloid beta (AB) 40 and AB42 (J Alzheimers Dis. 2017:59; 57-66).
RAGE helps mediate the transport of AB through the cell membrane and the blood brain barrier. S100B is a protein that has been implicated in the formation of tau tangles; other studies suggest that it interacts with RAGE to promote tau phosphorylation.
Compared to levels in the brains of white patients, brains of black patients contained 17% more S100B and 121% more AB42. The AB42/40 ratio was increased by almost 500% over that seen in the white sample.
The new, unpublished data used this same neuropathological cohort, but examined 40 known neuroinflammatory markers. Compared to the white sample, the black sample showed:
IL-1B, thought to increase amyloid precursor protein and promote tau phosphorylation, increased by 109% MIG, an attractant for activated T-cells, increased by 37%
TRAIL, a ligand that induces apoptosis. increased by 50%
“S 100 B is an astrocytic calcium binding protein,” Dr. Ferguson said. “We know that there are increased brain and cerebrospinal levels of S100 be in mild-moderate Alzheimer’s. S100 B can trigger neuroinflammatory signaling pathways. S100 B is also a potential biomarker of blood-brain barrier permeability. We see increased serum levels in such things as unmedicated schizophrenia and depression as well as brain injury.”
However, Dr. Ferguson said, “There were a couple of cytokines significantly that were decreased in African-American sample, including IL-8. Decreased IL-8 brain levels have been described in those with Alzheimer’s and recent studies have indicated that IL-8 may have a protective role in Alzheimer’s pathogenesis.”
IL-3, which activates mature neutrophils and macrophages, was also significantly decreased.
The researchers also saw some gender differences. Women had about 20% less CCL25 and CCL26 than men, and 32% less CxCL1 (fracktalkine). CCL26 (Eotaxin-3) was decreased significantly (19%) in women. Fractalkine is essential for microglial cell migration. CCL25 and CCL26 are also mobilizers of immune cells.
Dr. Ferguson postulated that at least some of this neuroinflammatory profile could be related to the formation of inflammasomes – multi-protein oligomeric structures formed in microglia in the brain by the influence of the NLRP3 gene.
“There is a lot of evidence that inflammasomes are involved in AD pathogenesis,” she said. Messenger RNA for the NLRP3 inflammasome is up-regulated in blood from AD patients. Alzheimer’s transgenic mice without the gene show decreased hippocampal and cortical AB40 and 42, increased microglial phagocytosis, and better memory. There is also some evidence that the NLRP3 inflammasome releases minute protein particles called apoptosis-associated (ASC) specks. Some researchers think these particles help seed amyloid throughout the brain. Based on these findings, Dr. Ferguson postulated a potential pathway for the increased prevalence and severity of AD among blacks.
Proinflammatory cytokines are released in response to rising AB levels. These promote the formation of the NLRP3 inflammasome within activated microglia. The inflammasome releases more chemokines and cytokines, leading to a chronic proinflammatory state that may actually promote amyloid seeding. This leads to synaptic dysfunction, cognitive dysfunction, and neuronal death
Dr. Ferguson said work on the samples will continue.
“We also have CSF and hippocampal tissue and intend to look at similar endpoints in those,” she said. “If as a result of this, we can find gene variants associated with ethnicity and Alzheimer’s, we may be able to establish genetic profiles to identify those at high risk. If we can do that, we may be able to intervene early before the person starts showing cognitive deficits and slow the progression of the disease – even develop precision medications for disease intervention.”

Compared to levels in the brains of white patients, brains of black patients contained 17% more S100B and 121% more AB42. The AB42/40 ratio was increased by almost 500% over that seen in the white sample.
The new, unpublished data used this same neuropathological cohort, but examined 40 known neuroinflammatory markers. Compared to the white sample, the black sample showed:
IL-1B, thought to increase amyloid precursor protein and promote tau phosphorylation, increased by 109% MIG, an attractant for activated T-cells, increased by 37%
TRAIL, a ligand that induces apoptosis. increased by 50%
“S 100 B is an astrocytic calcium binding protein,” Dr. Ferguson said. “We know that there are increased brain and cerebrospinal levels of S100 be in mild-moderate Alzheimer’s. S100 B can trigger neuroinflammatory signaling pathways. S100 B is also a potential biomarker of blood-brain barrier permeability. We see increased serum levels in such things as unmedicated schizophrenia and depression as well as brain injury.”
However, Dr. Ferguson said, “There were a couple of cytokines significantly that were decreased in African-American sample, including IL-8. Decreased IL-8 brain levels have been described in those with Alzheimer’s and recent studies have indicated that IL-8 may have a protective role in Alzheimer’s pathogenesis.”
IL-3, which activates mature neutrophils and macrophages, was also significantly decreased.
The researchers also saw some gender differences. Women had about 20% less CCL25 and CCL26 than men, and 32% less CxCL1 (fracktalkine). CCL26 (Eotaxin-3) was decreased significantly (19%) in women. Fractalkine is essential for microglial cell migration. CCL25 and CCL26 are also mobilizers of immune cells.
Dr. Ferguson postulated that at least some of this neuroinflammatory profile could be related to the formation of inflammasomes – multi-protein oligomeric structures formed in microglia in the brain by the influence of the NLRP3 gene.
“There is a lot of evidence that inflammasomes are involved in AD pathogenesis,” she said. Messenger RNA for the NLRP3 inflammasome is up-regulated in blood from AD patients. Alzheimer’s transgenic mice without the gene show decreased hippocampal and cortical AB40 and 42, increased microglial phagocytosis, and better memory. There is also some evidence that the NLRP3 inflammasome releases minute protein particles called apoptosis-associated (ASC) specks. Some researchers think these particles help seed amyloid throughout the brain. Based on these findings, Dr. Ferguson postulated a potential pathway for the increased prevalence and severity of AD among blacks.
Proinflammatory cytokines are released in response to rising AB levels. These promote the formation of the NLRP3 inflammasome within activated microglia. The inflammasome releases more chemokines and cytokines, leading to a chronic proinflammatory state that may actually promote amyloid seeding. This leads to synaptic dysfunction, cognitive dysfunction, and neuronal death
Dr. Ferguson said work on the samples will continue.
“We also have CSF and hippocampal tissue and intend to look at similar endpoints in those,” she said. “If as a result of this, we can find gene variants associated with ethnicity and Alzheimer’s, we may be able to establish genetic profiles to identify those at high risk. If we can do that, we may be able to intervene early before the person starts showing cognitive deficits and slow the progression of the disease – even develop precision medications for disease intervention.”
