To the Editor,

Star fruit (Averrhoa carambola) is an important tropical fruit that is widely ingested by local people in tropical countries. Of interest, this fruit can result in toxicity, and acute renal failure is possible in cases with intoxication. In a recent publication, Aranguren et al reviewed the case reports on the toxicity of star fruit in patients with underlying renal problems and concluded that “patients with already diagnosed chronic kidney disease (CKD) are the obvious target for preventive measures, but persons with undiagnosed kidney conditions could also be at risk.”[1] Herein, the authors would like to add more data on renal failure due to star fruit ingestion among Thai patients. According to aliterature review (in both international and local Thai databases), there are only three cases of renal failure reported due to the intake of star fruits in Thai patients.[2],[3] The ages of the patients were between 20 and 85 years. One case was acute deterioration of renal function in a patient with underlying CKD. In the other two cases without underlying CKD, the common history was drinking of enormous amount (more than 1 L) of fresh star fruit juice. The clinical complaint was acute anuria, and urine examination showed numerous oxalate crystals. Of interest, although star fruit is a common fruit and widely ingested by Thai people, there are very few cases of renal failure due to toxicity of star fruit. It can be concluded that appropriate amount of star fruit intake in people without underlying CKD is safe. In addition, it is suggested that persons with underlying CKD should avoid consuming star fruit.

Conflict of interest: None declared.
