No SARS-CoV-2 antibody response in 25 patients with pseudo-chilblains.

Chilblain-like acral lesions have been identified in some coronavirus disease 2019 (COVID-19) patients. It has been suggested that these pseudo-chilblains could be a specific marker of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Most patients with these lesions have had negative polymerase chain reactions (PCRs), but some authors believe serology tests are likely to give positive results.

Hidradenitis Suppurativa is Associated with Non-alcoholic Fatty Liver Disease: A Cross-sectional Study.

Non-alcoholic fatty liver disease (NAFLD) is currently the most common cause of end-stage liver disease. The aim of this controlled cross-sectional study was to assess the association between NAFLD and hidradenitis suppurativa. NAFLD was assessed using hepatic ultrasound.

Identification of bacterial DNA in the peripheral blood of patients with active hidradenitis suppurativa.

Bacterial translocation may have a role in the pathogenesis of several inflammatory conditions. A prospective analytical case-control study was designed to assess the presence of bacterial DNA in the peripheral blood of patients with hidradenitis suppurativa (HS). An age- and gender-matched control population was recruited from healthy blood donors.
