COVID-19 associated with onset nephrotic syndrome in a pediatric patient: coincidence or related conditions?

Background: COVID-19 is less frequent in children than in adults and affects the former less severely; despite the fact that respiratory symptoms are the most frequent, in some cases unusual manifestations can be seen.

Case-diagnosis: We present a 15-year-old boy who tested positive for SARS-COV-2 infection and onset of nephrotic syndrome, without antecedent of kidney disease and who had normal urine tests shortly before being affected by COVID-19.

Conclusions: The patient described in this report, who was admitted due to nephrotic syndrome and respiratory syndrome, tested positive for COVID-19.
