Abstract

<p>Star fruit (Avarrhoa carambola) is a fruit from oxalidace family. lt is found in many countries of the world including Bangladesh. But its ingestion or drinking star fruit juice may lead to intoxication especially in patients with chronic kidney disease and manifestations might be neurological or nephrological. lt may also cause acute kidney injury in patients with previously normal renal function. Here we are presenting a case who presented with acute kidney injury after star fruit ingestion with previously unknown renal function impairment. The etiology was confirmed by histopathological examination after doing renal biopsy. This renal function impairment is mainly due to oxalate crystal induce nephropathy which is richly abundant in star fruit. His renal function was improved ·with conservative management. Physicians should be alert to consider the ingestion of star fruit as a cause of acute kidney injury in a patient even in the absence of previous renal function impairment.</p>

Highlights

Star fruit, Avarrhoa carambola, is from Oxalidace family ( Figure 1)
Urine output was raised to[3] litres/day( from 250mVday on admission) and serum creatinine came down to 1 .2 gm/dl after eight days of his admission and he was discharged with a diagnosis of acute kidney injury due to star fruit toxicity with diabetes
Our patient presented initially with vomiting, hiccough and abdominal pain without any other types of neurological manifestations and subsequently developed acute kidney injury which improved with conservative management
