GIL, Ana I. et al. Severity of the gastroenteritis caused by vibrio parahaemolyticus of the pandemic group in Perú. Rev. perú. med. exp. salud publica [online]. 2007, vol.24, n.4, pp.350-355. ISSN 1726-4634.

Objective. To determine the epidemiological and clinic characteristics of gastroenteritis caused by Vibrio parahaemolyticus strains of the pandemic group in Peru. Material and methods. Clinical and laboratory records were searched in 100 cases of gastroenteritis caused by V parahaemolyticus, either of the pandemic or non pandemic group. Clinical and epidemiological data were collected and statistical analysis was done to evaluate if the severity of illness was associated with the pandemic group. Results. Epidemiological data were collected in 85% of cases, and clinical data were only available in 37% of cases, mainly on those hospitalized. Cases associated with the pandemic strains had a higher probability of liquid stools (96.3% vs. 62.5%, p<0.05), moderate or severe dehydration (100% vs. 60%, p<0.05), and hospital care (98% vs. 42.9%, p<0.0001). Cases aged thirty or older were associated with the pandemic strains (63% vs. 39.5%, p<0.05). Conclusions. Vibrio parahaemolyticus of the pandemic group causes more severe gastrointestinal disease than none pandemic strains, with higher probability of requiring hospital care. Based on this report, it is advisable to include the identification of V. parahaemolyticus in the etiological diagnosis of agents causing severe gastroenteritis in the Peruvian health system.
