Caractéristiques épidémiologiques et cliniques des gastro-entérites aiguës non invasives de l’enfant à l’hôpital de Cayenne

Abstract : Background: Rotavirus is the most common agent causing severe acute gastroenteritis (AGE) in children. No study had already been conducted in French Guiana to describe AGE. The aim of this work was to describe the epidemiology of acute gastroenteritis amongst children in Cayenne and the proportion of rotavirus. Methods: We carried out an epidemiological, descriptive, prospective and retrospective study at the Hospital of Cayenne (HC)between August 2016 and August 2017. All children consulting for non-bloody diarrhea were also included. During the prospective phase, a stool sample was collected for virological analysis. Results: During the study, 805 cases of acute gastroenteritis were identified. The average age was 2.9 years. We described a peak of AGE in March 2017 (n=109). Vomiting was associated with diarrhea in 79.75% of cases. Children under 5 years old had fewer stools and fewer symptoms. The percentage of dehydration was higher amongst children under 4 years old (3.72%±2.56, p<0.05). Children under 1 year old presented the highest hospitalization rate (15.15%, p=0.003). Rotavirus was detected in 29.87% of cases. The percentage of dehydration was higher in acute rotavirus gastroenteritis (4.25% vs 2.63%, p=0.0246). The rate of children rehydrated by intravenous administration (34.78%,NS) and hospitalized (21.74%,NS) was significantly higher amongst patients with acute rotavirus gastroenteritis. Conclusion: This first study showed the epidemiological and clinical characteristics of acute gastroenteritis amongst children in French Guiana and to revealed circulating viruses.
