Acute Kidney Injury Secondary to Severe Hand, Foot and Mouth Disease Caused by Enterovirus-A71: Hypertension Is a Common.

Hand, foot and mouth disease (HFMD) is a common infectious disease among children, caused primarily by human enterovirus-A71 (EV-A71) and coxsackievirus-A16 (CV-A16). To date, only two case reports mention that renal involvement can be secondary to or coexisting with CV-A16-associated HFMD. In the present report, we describe a 10-year-old girl who was infected with EV-A71 and subsequently developed a definite acute kidney injury (AKI), mainly based on the characteristic rash, virus isolation, eyelid edema, hypertension, decreased urine output, mild proteinuria and impaired renal function. She was treated with intravenous ribavirin, immunoglobulin, oral administration of nifedipine and ramipril. After 7 days of intensive observations, she recovered fully. Hypertension is a common feature in both HFMD and AKI. On one hand, hypertension serves as a risk factor for severe HFMD; on the other hand, hypertension induces AKI onset and is also deteriorated by AKI.
