Abstract
Star fruit (Averrhoa carambola) is a commonly available and popular fruit in many tropical and subtropical countries. Although star fruit induced oxalate nephropathy in patients with pre-existing renal impairment is well documented, reports on its effect on those with normal renal function are infrequent. Hereby we report a case where a young man with previously normal renal function presented with AKI that was attributable to consumption of star fruit. This write up illustrates the importance of obtaining the patient’s history with respect to ingestion of star fruit in case of sudden and unexplained development of renal impairment.J MEDICINE Jan 2018; 19 (1) : 63-65
Highlights
Acute kidney injury (AKI) is a syndrome characterized by the rapid loss of the kidney's excretory function along with an abrupt decline in the glomerular filtration rate (GFR) leading to accumulation of end products of nitrogen metabolism, and is typically diagnosed by increased level of urea and creatinine or decreased urine output or both
We report a case of star fruit induced AKI in a person with previously normal renal function
The first report describing star fruit induced oxalate nephrotoxicity in humans was published in 2001.1 The authors looked into two cases where the patients developed AKI after having star fruit juice; their kidney biopsies revealed histological findings consistent with acute oxalate nephropathy
Summary
Acute kidney injury (AKI) is a syndrome characterized by the rapid loss of the kidney's excretory function along with an abrupt decline in the glomerular filtration rate (GFR) leading to accumulation of end products of nitrogen metabolism (urea and creatinine), and is typically diagnosed by increased level of urea and creatinine or decreased urine output or both. Patient was moderately dehydrated and he was started an intra venous fluid They advised serum creatinine which was found 5.4 mg/dL. On further query to his dietary history, he said that first he started to feel nauseated, 4-5 hours after taking sliced star fruit at home. At that time he returned home from work and took them in empty stomach. We offered renal biopsy to the patient with proper concealing but he denied His past and presumptive history make it quite clear that, start fruit was the culprit. Patient was followed up with serum creatinine and urinalysis which came normal
