A hyperinflammatory environment has been a hallmark of COVID-19 infection and is thought to be a key mediator of morbidity. Elevated ferritin has been observed in many patients with COVID-19. Several retrospective studies have shown ferritin levels can be correlated and predictive of poor outcomes in COVID-19, though a rigorous analysis has been lacking. ⋯ Though many patients with COVID-19 present with hyperferritinemia, elevated ferritin levels are not accurate predictors of outcomes and do not appear to be indicative of hemophagocytic lymphohistiocytosis.

Congenital fibrinogen disorders (CFDs) comprise the quantitative and qualitative fibrinogen molecule abnormalities that are caused by fibrinogen gene mutations. The objective of this cohort research was to study the molecular and clinical profiles of patients with CFDs. ⋯ In Iran, with its high rate of consanguinity, autosomal recessive afibrinogenemia with severe clinical presentations is relatively common due to heterogeneous molecular defects.
