Background The novel coronavirus disease (COVID-19) emerged from China in 2019 and rapidly spread worldwide. Patients with metabolic comorbid conditions are more susceptible to infection by COVID-19. Metabolic syndrome is a constellation of interlinked metabolic risk factors that predispose patients to increased risk of complications. Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and non-alcoholic steatohepatitis (NASH) is the aggressive form of NAFLD. Objective The aim of this study is to determine the relationship between metabolic syndrome components and the risk of COVID-19. Methods We reviewed data from a large commercial database (Explorys IBM) that aggregates electronic health records from 26 large nationwide healthcare systems. Using systemized nomenclature of clinical medical terms (SNOMED-CT), we identified adults with the diagnosis of metabolic syndrome and its individual components from 1999-2019. We included patients with the diagnosis of COVID-19 from December 2019 to May 2020. Comorbidities known to be associated with COVID-19 and metabolic syndrome such as obesity, diabetes mellitus, dyslipidemia, smoking, male gender, African American, and hypertension were collected. Univariable and multivariable analyses were performed to investigate whether metabolic syndrome or its individual components are independently associated with the risk of COVID-19. Results Out of 61.4 million active adult patients in the database, 8,885 (0.01%) had documented COVID-19. The cumulative incidence of COVID-19 was higher if metabolic syndrome was the primary diagnosis (0.10% vs 0.01% %, OR 7.00 [6.11–8.01]). The adjusted odds (aOR) of having COVID-19 was higher in patients if they were African Americans (OR 7.45 [7.14- 7.77]), hypertensive (aOR 2.53 [2.40 - 2.68]), obese (aOR 2.20 [2.10 2.32]), diabetic (aOR 1.41 [1.33- 1.48]) hyperlipidemic (OR 1.70 [1.56-1.74]) or diagnosed with NASH (OR 4.93 [4.05- 6.00]). There was a slight decrease in adjusted odds of having COVID-19 in males as compared to females (aOR 0.88 [0.84- 0.92]). Conclusion The incidence of COVID-19 in patients with metabolic syndrome is high. Among all comorbid metabolic conditions, NASH had the strongest association with COVID-19.

Granuloma annulare (GA) is a benign inflammatory dermatosis characterized clinically by dermal papules and annular plaques. The pathogenesis of GA is not well understood, although it is thought to result from a delayed-type hypersensitivity reaction in which inflammatory cells elicit connective tissue degradation. This condition has been seen following the use of several drugs, including tumor necrosis factor-alpha (TNF-α) inhibitors, which paradoxically have also been reported to treat GA. We report the case of a patient who developed GA in association with secukinumab, an interleukin-17A antagonist, and discuss its implications for our understanding of the pathogenesis of GA.

Bullous pemphigoid (BP) is a chronic relapsing autoimmune blistering disease that typically affects middle-age and elderly patients. It can manifest with varying degrees of mucosal involvement in addition to characteristic skin findings. However, esophageal involvement is very rare. We report a case of a 57-year-old female with BP who presented with epigastric pain and melena. She underwent an esophagogastroduodenoscopy which induced bullae seen only upon withdrawal of the endoscope. This finding is analogous to the dermatological finding of Nikolsky's sign. Gentle insertion and withdrawal of the endoscope is recommended to reduce the risk of bullae formation and mucosal injury.

Background: Inflammatory bowel disease (IBD) has been associated with an increased risk of cardiovascular events, but the risk of cerebrovascular accidents (CVA) remains unknown. Hypercoagulability and systemic inflammation are two proposed mechanisms by which the presence of IBD might lead to the development of CVA. Objective: To assess the risk of CVA in patients with IBD compared to those without IBD with known traditional risk factors for CVA. Methods: We reviewed data from a large commercial database (Explorys, IBM) that aggregated records from 26 health-care systems nationwide. Using systemized nomenclature of medicineclinical terms, we identified adult patients diagnosed with IBD (ulcerative colitis or Crohn's disease) between September 1994 and September 2019. We then examined the risk of CVA in these patients. Known risk factors such as age ≥65-years old, diabetes mellitus (DM), hypertension (HTN), female gender, atrial fibrillation (Afib) were collected. A univariate binary logistic model was constructed using CVA as the dependent variable and other variables as independent variables. To adjust for possible confounding, a multivariable model adjusting for all covariates was created to test for CVA. Results: A total of 52,176,550 patients were included in this analysis, and 261,890 had IBD. The prevalence of CVA was higher in IBD patients compared to non-IBD patients (6.24% versus 0.48%, p <0.0001). The univariate binary logistic regression showed 13.7 times higher odds of having CVA in IBD patients than without IBD (odds ratio (OR) 13.74, p <0.0001). In multivariate binary logistic regression, after adjusting for traditional risk factors for CVA (Afib, HTN, female gender, DM, age ≥65 years), odds ratio of CVA in IBD patients remained significantly higher (OR 8.07, 95% CI: 7.9-8.2, p<0.0001). Conclusion:In our large cohort of patients, IBD appears to be an independent risk factor for CVA. Further prospective studies are needed to understand the underlying mechanisms by which IBD increases the risk of CVA. This may lead to early identification and intervention to reduce the risk of CVA in this highly heterogeneous group of patients.

BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a systemic disease with bidirectional relationships with cardiovascular disease (CVD). Non-alcoholic steatohepatitis (NASH) is a more severe subtype of NAFLD. Patients with NASH exhibit more intra and extrahepatic inflammation, procoagulant imbalances and proatherogenic lipid profiles. Whether NASH increases the risk of ischemic heart disease is currently unclear. AIM To investigate the relationship between acute myocardial infarction (MI) and NASH in a large cohort of subjects in the United States. METHODS We reviewed data from a large commercial database (Explorys IBM) that aggregates electronic health records from 26 large nationwide healthcare systems. Using systemized nomenclature of clinical medical terms (SNOMED CT), we identified adult with the diagnosis of NASH from 1999-2019. We included patients with the diagnosis of acute MI from 2018-2019. Comorbidities known to be associated with NASH and MI such as obesity, diabetes mellitus, hyperlipidemia, smoking, male gender, and hypertension were collected. Univariable and multivariable analyses were performed to investigate whether NASH is independently associated with the risk of MI. RESULTS Out of 55099280 patients, 43170 were diagnosed with NASH (0.08%) and 107000 (0.194%) had a MI within 2018-2019. After adjusting for traditional risk factors, NASH conferred greater odds of MI odds ratio (OR) 1.5 [95% confidence interval (CI): 1.40-1.62]. Hyperlipidemia had the strongest association with MI OR 8.39 (95%CI: 8.21-8.58) followed by hypertension OR 3.11 (95%CI: 3.05-3.17) and smoking OR 2.83 (95%CI: 2.79-2.87). NASH had a similar association with MI as the following traditional risk factors like age above 65 years OR 1.47 (95%CI: 1.45-1.49), male gender OR 1.53 (95%CI: 1.51-1.55) diabetes mellitus OR 1.89 (95%CI: 1.86-1.91). CONCLUSION MI appears to be a prevalent disease in NASH. Patients with NASH may need early identification and aggressive cardiovascular risk modification.
