title: Star fruit intoxication in a chronic renal failure patient: case report.
abstract: Chronic renal failure is a high morbidity and mortality condition, with its terminal phase incidence and prevalence steadily growing year after year. According to the Sociedade Brasileira de Nefrologia [Brazilian Society of Nephrology], the main causes of renal failure are arterial hypertension, glomerulonephritis and diabetes mellitus. Several factors are implied on chronic renal failure patients' risk of mortality, particularly age, diabetes and associated co-morbidities. For patients below 50 years old, the 5 years survival rate is 62% and for those above this age and with diabetes mellitus, just 23%. Star fruit is native from Asia, and widespread in tropical countries; this fruit was reported as having a neurotoxin able to cause serious neurological changes in chronic renal disease patients. These may range from mild features, such as hiccup and confusion, to serious episodes with seizures and death. This neurotoxin apparently inhibits specifically the GABAergic conduction system. This paper describes a case involving a chronic renal disease patient who, after ingesting star fruit, featured malaise, nausea and vomiting, followed by repeated convulsions and died even though undergoing conventional hemodialysis therapy.
