Abstract: Vibrio cholerae O139 synonym Bengal, recognized in 1993, is the second member in the list of about 200 serogroups of V. cholerae with epidemic and pandemic potential. Although replacement of fluids and electrolytes remains the cornerstone in the management of cholera, antimicrobial therapy can significantly shorten the duration of diarrhoea, and reduce stool volume and requirements ofrehydration fluids. The role of antimicrobial therapy on the natural course of the disease caused by this relatively new pathogen has not been systematically assessed. A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the efficacy of tetracycline in the treatment of adults with severe cholera due to V. cholerae O139 Bengal. Forty-three adult males with severe cholera were randomly allocated to receive either 500 mg of tetracycline (n=21) or placebo (n=22) for three consecutive days. Demographic and clinical characteristics of these patients on admission were comparable. Tetracycline therapy was associated with significantly reduced total median (inter-quartile range) stool volume [216.48 (90.18-325.22) mL/kg vs 334.25 (215.12-537.64) mL/kg; p=0.001], higher rates of clinical cure (81% vs 27%; p<0.001), and shorter median (inter-quartile range) duration of diarrhoea [32 (24-48) hours vs 80 (48-104) hours; p<0.001]. The mean +/- (SD) requirement of intravenous fluid was not significantly different between the two groups [146.42 +/- 42.12 mL/kg vs 150.44 +/- 27.21 mL/kg; p=0.70]. The median (inter-quartile range) duration of faecal excretion of V. cholerae O139 was significantly shorter in the tetracycline group than the placebo group [1(1-2) day vs 5 (3-6) days; p<0.001]. The results of the study indicate that tetracycline therapy is clinically useful in the treatment of severe cholera due to V. cholerae O139 Bengal.
