In our cohort of HIV-infected youth, a 12-month cholecalciferol supplementation increased 25(OH)D and 1-25(OH)2D and decreased PTH levels but had no effect on CD4+ T-cells. However, it was associated with changes in CD4+ T-cell phenotype, warranting further investigation.

Exposure to TDF during pregnancy does not impair growth patterns, bone health and markers of bone metabolism in SR infants and young children born to HIV-infected women.

Severe acute respiratory syndrome coronavirus 2 infection in children mainly shows a milder course. In complicated cases, it is unknown whether inflammation is predictive of disease severity, as in adults. Moreover, cardiac involvement is anecdotally described. We report the case of a 2-month-old infant with severe acute respiratory syndrome coronavirus 2 infection presenting with fever, tachycardia and elevated interleukin-6, who was diagnosed with myocarditis and treated with immunoglobulins.
