    Abstract: A sex discordance in COVID exists, with males disproportionately affected. Although sex steroids may play a role in this discordance, no definitive genetic data exist to support androgen-mediated immune suppression neither for viral susceptibility nor for adrenally produced androgens. Objective The common adrenal-permissive missense-encoding variant HSD3B1(1245C) that enables androgen synthesis from adrenal precursors and that has been linked to suppression of inflammation in severe asthma was investigated in COVID susceptibility and outcomes reported in the UK Biobank. Methods The UK Biobank is a long-term study with detailed medical information and health outcomes for over 500 000 genotyped individuals. We obtained COVID test results, inpatient hospital records, and death records and tested for associations between COVID susceptibility or outcomes and HSD3B1(1245A/C) genotype. Primary analyses were performed on the UK Biobank Caucasian cohort. The outcomes were identification as a COVID case among all subjects, COVID positivity among COVID-tested subjects, and mortality among subjects identified as COVID cases. Results Adrenal-permissive HSD3B1(1245C) genotype was associated with identification as a COVID case (odds ratio (OR): 1.11 per C allele, 95% CI: 1.04–1.18, P  = 0.0013) and COVID-test positivity (OR: 1.09, 95% CI: 1.02–1.17, P  = 0.011) in older (≥70 years of age) women. In women identified as COVID cases, there was a positive linear relationship between age and 1245C allele frequency (P  & lt; 0.0001). No associations were found between genotype and mortality or between genotype and circulating sex hormone levels. Conclusion Our study suggests that a common androgen synthesis variant regulates immune susceptibility to COVID infection in women, with increasingly strong effects as women age.

    Abstract: Asthma resistance to glucocorticoid treatment is a major health problem with unclear etiology. Glucocorticoids inhibit adrenal androgen production. However, androgens have potential benefits in asthma. HSD3B1 encodes for 3β-hydroxysteroid dehydrogenase-1 (3β-HSD1), which catalyzes peripheral conversion from adrenal dehydroepiandrosterone (DHEA) to potent androgens and has a germline missense-encoding polymorphism. The adrenal restrictive HSD3B1 (1245A) allele limits conversion, whereas the adrenal permissive HSD3B1 (1245C) allele increases DHEA metabolism to potent androgens. In the Severe Asthma Research Program (SARP) III cohort, we determined the association between DHEA-sulfate and percentage predicted forced expiratory volume in 1 s (FEV 1 PP). HSD3B1 (1245) genotypes were assessed, and association between adrenal restrictive and adrenal permissive alleles and FEV 1 PP in patients with (GC) and without (noGC) daily oral glucocorticoid treatment was determined ( n = 318). Validation was performed in a second cohort (SARP I & II; n = 184). DHEA-sulfate is associated with FEV 1 PP and is suppressed with GC treatment. GC patients homozygous for the adrenal restrictive genotype have lower FEV 1 PP compared with noGC patients (54.3% vs. 75.1%; P 〈 0.001). In patients with the homozygous adrenal permissive genotype, there was no FEV 1 PP difference in GC vs. noGC patients (73.4% vs. 78.9%; P = 0.39). Results were independently confirmed: FEV 1 PP for homozygous adrenal restrictive genotype in GC vs. noGC is 49.8 vs. 63.4 ( P 〈 0.001), and for homozygous adrenal permissive genotype, it is 66.7 vs. 67.7 ( P = 0.92). The adrenal restrictive HSD3B1 (1245) genotype is associated with GC resistance. This effect appears to be driven by GC suppression of 3β-HSD1 substrate. Our results suggest opportunities for prediction of GC resistance and pharmacologic intervention.
