ABSTRACT

Sarcoidosis is a chronic granulomatous disease predominantly affecting the lungs and inducing significant morbidity and elevated mortality rate. The etiology of the disease is unknown but may involve exposure to an antigenic agent and subsequent inflammatory response resulting in granuloma formation. Various environmental and occupational risk factors have been suggested by previous observations, such as moldy environments, insecticides, and bird breeding. Our study investigated the association of air pollution with diagnosis of sarcoidosis using a case-control design. Penn State Health electronic medical records from 2005 to 2018 were examined for adult patients with (cases) and without (controls) an International Classification of Disease (ICD)-9 or -10 code for sarcoidosis. Patient addresses were geocoded and 24-hr residential-level air pollution concentrations were estimated using spatio-temporal models of particulate matter <2.5 µm (PM2.5), ozone, and PM2.5 elemental carbon (EC) and moving averages calculated. In total, 877 cases and 34,510 controls were identified. Logistic regression analysis did not identify significant associations between sarcoidosis incidence and air pollution exposure estimates. However, the odds ratio (OR) for EC for exposures occurring 7-10 years prior did approach statistical significance, and ORs exhibited an increasing trend for longer averaging periods. Data suggested a latency period of more than 6 years for PM2.5 and EC for reasons that are unclear. Overall, results for PM2.5 and EC suggest that long-term exposure to traffic-related air pollution may contribute to the development of sarcoidosis and emphasize the need for additional research and, if the present findings are substantiated, for public health interventions addressing air quality as well as increasing disease surveillance in areas with a large burden of PM2.5 and EC.

ABSTRACT

INTRODUCTION: Herpes zoster increases stroke and myocardial infarction risk. The objective of this study is to evaluate the impact of live attenuated zoster vaccination on stroke and myocardial infarction risk in patients at risk of zoster, including those with hypertension, diabetes mellites, obesity, hypercholesterolemia, chronic kidney disease, chronic obstructive pulmonary disease, emphysema, asthma, and chronic liver disease. METHODS: This is a retrospective cohort study utilizing continuous de-identified claims data from the IBM MarketScan Commercial Claims and Encounters Database (collected from 2005-2018) containing data for 200 million commercially insured Americans. Participants included 27,093 adults vaccinated against zoster with at least 5 years of continuous enrollment, age and sex-matched 1:5 with unvaccinated controls. OR, risk difference, and the number needed to treat evaluated the effect of vaccination on stroke and myocardial infarction while controlling for relevant comorbidities. RESULTS: Over the period of 5 years, proportions of myocardial infarction (1.29% vs 1.82%; p<0.05) and stroke (1.61% vs 2.20%; p<0.05) were lower in vaccinated versus unvaccinated individuals, respectively, controlling for age and sex, with the greatest benefit for people with diabetes (stroke OR=0.64, 95% CI=0.58, 0.71; myocardial infarction OR=0.63, 95% CI=0.57, 0.71). Although hypertension and chronic obstructive pulmonary disease had the highest odds of stroke and myocardial infarction, vaccination still provided significant risk-reduction (hypertension: stroke 0.75 [0.68, 0.83], myocardial infarction 0.73 [0.65, 0.81]; chronic obstructive pulmonary disease: stroke 0.75 [0.68, 0.83], myocardial infarction 0.74 [0.66, 0.83]). CONCLUSIONS: Live attenuated zoster vaccination is associated with lower risk of stroke and myocardial infarction in adults with at-risk comorbidities, controlling for age and sex. Vaccination may provide cardiovascular benefits beyond zoster prevention.

ABSTRACT

Though more common earlier in life, increasing attention is being focused on the development of cutaneous lupus erythematosus (CLE) in patients with advancing age. Studies show that CLE is more common in older populations than previously thought, and all CLE subtypes are possible in this group. Just like patients in the third or fourth decade of life, CLE may appear alongside or independent of systemic lupus erythematosus. Older populations manifesting CLE for the first time seem to have a lower risk of progression to systemic disease than younger peers, and are more commonly White. CLE must be carefully distinguished from other skin conditions that have a predilection for presentation in older populations, including rosacea, lichen planus, and other autoimmune conditions such as dermatomyositis or pemphigus/pemphigoid. It is thought that most CLE in older populations is drug-induced, with drug-induced subacute cutaneous lupus erythematosus being the most common subtype. Management of CLE in older patients focuses on eliminating unnecessary medications known to induce CLE, and otherwise treatment proceeds similarly to that in younger patients, with a few special considerations.

ABSTRACT

BACKGROUND: Herpes zoster increases the risk for stroke and myocardial infarction. Zoster vaccination's impact on this risk is understudied. This retrospective work sought to determine if prophylactic herpes zoster vaccination may reduce the risk of stroke, myocardial infarction, and/or mortality. METHODS: A cohort analysis utilized TriNetX, a national, federated database. In one analysis, patients who received 2 doses of recombinant zoster vaccine (RZV) were compared to adults without RZV. A 1:1 propensity-score match analysis was conducted to adjust for demographics and comorbidities in calculating adjusted relative risks (aRR) with 95% confidence intervals. First-time incidences for myocardial infarction, stroke, and mortality were assessed after 3 years. A subgroup analysis between RZV and zoster vaccine live (ZVL) was also assessed. RESULTS: Matched cohorts of 7,657 patients revealed that adults who received 2 doses of RZV were at lower risk of MI (aRR [95% CI]) = (0.73 [0.55, 0.96]) and mortality (0.7 [0.57, 0.88]) while having similar risk for stroke (0.97 [0.75, 1.26]). Further subgroup analysis also revealed a reduced risk of 3-year mortality when compared to the ZVL cohort (0.84 [0.74, 0.95]). Sample size and comorbidities included in the analysis were limited by using a large database. CONCLUSIONS: RZV reduces the 3-year risk for myocardial infarction and mortality.

ABSTRACT

Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy (IIM) associated with an increased risk for malignancy. Although cancer screening is recommended, no consensus guidelines currently exist. Whole-body positron emission tomography/ computed tomography (PET/CT) has similar cost and efficacy to a more traditional conventional cancer screening panel (CSP). Our study sought to characterize patients' perspective of cancer screening and the indirect costs to patients. We conducted a survey of patients recently diagnosed with DM who were undergoing or had recently undergone a CSP. Patient values and indirect costs need to be considered in choosing a screening modality. This study contributes to a greater understanding of patients' experience of cancer screening in DM, which should be taken into consideration when developing consensus guidelines for cancer screening.

ABSTRACT

BACKGROUND: Mohs surgery (MS) is the gold standard for treating nonmelanoma skin cancers in cosmetically sensitive areas. OBJECTIVE: To investigate MS costs over time when adjusting for medical inflation while considering the perspective of patients, payers, and health care systems. METHODS: A retrospective claim analysis using data from the International Business Machines MarketScan Commercial Claims and Encounters Database from 2007 through 2019 was performed. A query of the database for any instance of a MS-specific Current Procedural Terminology (CPT) code in adults (17311, 17312, 17313, 17314, and 17315) was conducted. Aggregate data per claim regarding coinsurance, total cost, deductible, copay, and insurance payout were provided for each CPT code annually. RESULTS: The total adjusted cost per claim decreased significantly (P < .001) for 4 of the 5 MS-specific CPT codes between 2007 and 2019: 17311 (-25%), 17312 (-15%), 17313 (-25%), and 17314 (-18%). The patient's adjusted out-of-pocket expense increased significantly (P < .0001) for 4 of the 5 MS-specific CPT codes: 17311 (33%), 17312 (45%), 17313 (34%), and 17314 (43%). CONCLUSION: Among the 4 most used MS-specific CPT codes (17311, 17312, 17313, and 17314), the total cost per claim decreased and the patient's out-of-pocket expense increased from 2007 to 2019.

ABSTRACT

Cutaneous lupus erythematosus (CLE) is a spectrum of skin changes related to systemic lupus erythematosus (SLE), a family of autoimmunity manifesting characteristic multisystem inflammation and damage. Treatment of CLE continues to evolve, especially for patients with moderate to severe disease. Type 1 interferon (IFN-1) plays a significant role in CLE pathogenesis. Anifrolumab, a fully humanized monoclonal antibody, selectively binds and inhibits the IFN-α receptor 1. Evidence from multiple Phase II and III randomized trials resulted in approval for anifrolumab for treatment of moderate to severe SLE. We present a case series of three patients with refractory CLE significantly improved with anifrolumab. The patients were recruited via clinic interaction and treated with anifrolumab from January 2021 to April 2022. Each patient received at least 12 weeks of therapy. Treatment and follow-up is ongoing. Patients were eligible for the study if they were a patient of the UNC Hospital System with resistant CLE, defined as having received inadequate disease control with standard therapies, including antimalarials, disease-modifying agents and biologics. Outcome measures were improvement in patient-reported symptoms and physician observation of erythema and pigmentary changes. All cases demonstrated significant improvement in disease appearance, cutaneous involvement, and symptomology after treatment with 2 months of anifrolumab infusions. Anifrolumab shows great potential for improving CLE in patients who have failed standard of care and multiple treatment options, including those that have failed belimumab or those who smoke. This report highlights the value of anifrolumab in managing patients with refractory CLE.

ABSTRACT

Importance: Hidradenitis suppurativa (HS) is a chronic autoinflammatory disease that is highly associated with affective disorders such as depression and anxiety. Recent studies have shown that patients with HS may also endorse high levels of internalized skin bias (ISB). This redirection of skin disease-related social stigma toward oneself may also play an important role in the associations between adverse psychopathology (eg, depression, anxiety) and health-related quality of life (HRQOL). Objectives: To evaluate the associations of ISB with other core outcomes in HS and to determine if ISB may mediate the associations between adverse psychopathological outcomes and impaired HRQOL. Design, Setting, and Participants: A cross-sectional study of adult patients with HS recruited from 1 academic medical center as well as through virtual social and recruitment networks. Eligible participants completed an online survey comprised of 4 survey instruments along with demographic and disease history information from April 1, 2021, to July 15, 2021. Main Outcomes and Measures: Measures included the Internalized Skin Bias Questionnaire (ISBQ), Burns Anxiety Inventory, the Beck Depression Inventory-II, the Hidradenitis Suppurativa Quality of Life (HiSQOL) instrument, along with demographic and disease history information. The primary outcome was HRQOL as measured by the HiSQOL. Data were analyzed in July through August 2021. Results: The survey was completed by 230 of 279 patients (82.4%; mean [SD] age, 39.2 [11.2] years; 209 [90.9%] identified as female, 203 [88.7%] as not Hispanic, 178 [77.7%] as White). Depression and anxiety were shown to be a substantial burden in this sample, with 56.5% of participants' scores qualifying for moderate or greater anxiety and 45.7% moderate or greater depression. The mean (SD) HRQOL scores were moderately high at 34.5 (16.7), indicating strong levels of impairment. There was a moderate correlation between ISBQ score and depression (r = 0.67); and fair correlations with HRQOL (r = 0.52) and anxiety (r = 0.56). Therefore, ISB appears to positively mediate the associations between depression and anxiety (estimated proportions of total effect that were mediated, 38.7% and 24.9%, respectively) and HRQOL. After controlling for age, disease severity, and disease duration, both ISB and anxiety were positive predictors of impaired HRQOL. Conclusions and Relevance: This cross-sectional study found that ISB was associated with adverse psychopathology and impaired HRQOL in patients with HS. Furthermore, ISB appears to mediate the associations of depression and anxiety with HRQOL. Future studies are needed to design interventions targeted at addressing adverse psychopathology associated with ISB and improving HRQOL and well-being for patients with HS.

ABSTRACT

This case series discusses 3 patients with long-standing eczematous or psoriasiform dermatitis, demonstrated by multiple biopsies. Following off-label treatment with dupilumab, all 3 patients had clinical expansion of disease, with histopathologic features consistent with cutaneous T-cell lymphoma (CTCL) on subsequent biopsy. We postulate that this expansion likely was secondary to an exacerbation of extant CTCL following exposure to dupilumab. A proposed mechanism of promotion of CTCL is based on the functional increase in IL-13 available for binding at the upregulated IL-13 receptor (IL-13R) α2 site on cells, following blockade of the α1 receptor with dupilumab. This progression merits further investigation.

ABSTRACT

Poland syndrome is a rare congenital disorder characterized by agenesis of the pectoralis major muscle. It is generally unilateral, right-sided, and can be associated with a myriad of thoracic and upper limb defects. Knowledge of this disorder can lead the astute clinician to prompt diagnosis and referral to surgical specialists for further workup. Surgery is often performed for either esthetic or functional concerns.

ABSTRACT

Background: Dermoscopy is well established as a tool to improve the detection of cancerous skin growths. Published data suggest that dermoscopy might be useful in evaluating inflammatory dermatoses and in distinguishing between rashes and skin cancer. Objective: The authors sought to review the published literature regarding use of dermoscopy in the evaluation of inflammatory skin conditions. Methods: Using a systematic approach, the authors performed a literature search using the names of 146 inflammatory dermatoses and pairing each one separately with the search terms dermoscopy, dermatoscopy, and epiluminescence microscopy.Results: After eliminating those papers that did not meet inclusion requirements, the authors identified 201 studies for their review, with the majority consisting of case reports. The most commonly studied inflammatory conditions were psoriasis, lupus, and lichen planus. There was congruence among the studies identified in terms of the most common dermoscopic findings for each of these diseases. Conclusions: The use of dermoscopy in the evaluation of inflammatory dermatoses is a promising option. However, more rigorous studies are needed to determine the sensitivity and specificity of the dermoscopic findings for many inflammatory skin conditions.

ABSTRACT

Lentigo formation has been described in adults after the resolution of psoriatic plaques treated with various standard psoriasis treatments. We describe three cases of lentigines developing in areas of resolving psoriatic plaques: two in patients treated with etanercept and one before starting etanercept. A possible pathomechanism is proposed.
