Abstract
OBJECTIVE
1. To study the clinical features in patients with Cleistanthus collinus poisoning, 2. To study in them the effect of Cleistanthus collinus poisoning on the various organ systems and metabolic parameters using standard laboratory investigations.
METHODS
All patients admitted to the hospital between September 1998 and April 2000 were studied. Statistical analysis of the results was done using chi-square test, Fisher's exact test and Student's 't' test.
RESULTS
Forty six cases were studied, 15 (32%) of whom died. Eighty percent of the patients were in the second to third decade. The female:male ratio was 3:2. Ingestion of the poison as a decoction prepared from the leaves and ingestion of a large number of leaves otherwise were associated with a poor outcome. While survivors remained relatively asymptomatic, fatally poisoned patients presented with significant clinical signs and symptoms, however, laboratory abnormalities such as hypokalaemia, hyponatremia, an elevated AST/LDH/CPK/CPK-MB, nonspecific ST-T changes and QTc prolongation on ECG, metabolic acidosis and hypoxia with widened alveolar-arterial oxygen difference (A-aDO2) were seen in both groups.
CONCLUSIONS
It is a poisoning seen in the young with significant mortality. Cause of death appears to be mainly due to its cardiac and respiratory effects. Metabolic disturbances especially hypokalaemia was a prominent feature. Most deaths occurred on the 3rd day and all within a week. No specific antidote is available.
