Abstract

Renal histology results are very scarce in dengue-associated rhabdomyolysis patients developing acute kidney injury (AKI). We report a case of dengue fever-induced AKI associated to rhabdomyolysis with a renal biopsy showing acute tubular necrosis (ATN) and renal deposition of myoglobin. A 28-year-old patient who presented dengue fever (DF) complicated by severe AKI and rhabdomyolysis is described. The patient required hemodialysis for three weeks. A renal biopsy revealed ATN with positive staining for myoglobin in the renal tubuli. The patient was discharged with recovered renal function. In conclusion, this case report described a biopsy proven ATN associated to DF-induced rhabdomyolysis, in which renal deposition of myoglobin was demonstrated. We suggest that serum creatine phosphokinase should be monitored in DF patients to allow for an early diagnosis of rhabdomyolysis and the institution of renal protective measures.Resultados de histologia renal são muito escassos em pacientes com rabdomiólise e injúria renal aguda (IRA) associada a dengue. Descrevemos caso de dengue complicado por rabdomiólise e IRA no qual a biópsia renal mostrou necrose tubular aguda (NTA) e deposição renal de mioglobina. Paciente de 28 anos que apresentou dengue complicado por IRA grave e rabdomiólise é descrito. Ele necessitou de diálise por três semanas. A biópsia renal mostrou NTA, com imunohistoquímica fortemente positiva para mioglobina nos túbulos renais. O paciente recebeu alta com recuperação da função renal. Em conclusão, descrevemos caso de dengue complicado por IRA e rabdomiólise, em que a biópsia renal mostrou NTA e deposição de mioglobina. Sugerimos que creatinofosfoquinase deve ser monitorizada em pacientes com dengue para permitir o diagnóstico precoce de rabdomiólise e a instituição de medidas protetoras para o rim.
