The primary purpose of the current study was to examine whether patients with rheumatologic conditions receiving only chronic hydroxychloroquine therapy for their disease are at less risk of developing SARS-CoV-2 infection than a comparative group of patients without rheumatologic conditions. ⋯ Hydroxychloroquine failed to demonstrate a preventative effect against SARS-CoV-2 infection in a large group of patients with rheumatologic conditions compared to patients without rheumatologic conditions.

Eosinophil count, dyslipidemia, and metabolic syndrome (MetS) are associated with systemic inflammation. We conducted this large population-based study to investigate the association between elevated eosinophil count, serum lipids, and MetS in the Taiwanese population. ⋯ High eosinophil count is an independent risk factor for MetS. Hypertriglyceridemia and hypo-HDL-cholesterolemia might partly contribute to this result.

The association between statins and incident diabetes mellitus (DM) in observational studies is much larger than that reported from randomized controlled trials. We sought to assess this association using a novel design controlling for selection bias. ⋯ Statin use was strongly associated with incident diabetes when users were compared to non-users but not when continuers were compared to discontinuers. Selection bias confounds the association between statin use and incident diabetes in observational studies.

Little is known about the prevalence of HFE (homeostatic iron regulator) hemochromatosis in African Americans (AA). ⋯ We conclude that ∼1/25,061 AA >18 y have a hemochromatosis-associated HFE genotype and IO and that ∼1/32,103 AA >18 y have a hemochromatosis-associated HFE genotype and IO-related disease.
