Clinical Characteristics of Rotavirus-Induced Gastroenteritis in Infants

Abstract

Abstract Rotavirus is the most common cause of acute infectious diarrhea in infants and young children up to the age of five. The disease is characterized by profuse watery diarrhea, vomiting and fever. The major complications of rotavirus gastroenteritis (RVGE) are dehydration, middle ear inflammation and upper respiratory tract infection. The basis of treatment is compensation for fluid loss and administration of probiotics. The aim of this study was to analyze the clinical characteristics of rotavirus gastroenteritis in infants. The study was conducted by the type of retrospective-prospective clinical study on infants with rotavirus gastroenteritis diagnosed on the basis of a positive Rotalex test (Orion Diagnostica Finland) and exclusion of other etiological factors at the University Children's Clinic in Belgrade, from April 2005 to December 2010. In addition to the detailed medical history and clinical examination, relevant laboratory analyzes were performed in all patients. Descriptive and analytical statistical methods were applied in the study. Among the descriptive methods, we used grouping, tabulation, graphing, calculating measures of central tendency, calculating measures of variability and calculating relative numbers. Of the analytical statistical methods, distribution normality testing, χ2 test, Mann-Whitney U test and T test were used. Statistical significance will be taken to mean p < 0.05. The average infant mortality was 6.7 ± 3.7 months. All respondents were divided into two groups according to the age. The first group consisted of infants aged 0 to 5 months (46%), the second group consisted of infants aged 6 to 12 months (54%). The incidence of aqueous diarrhea (100%), vomiting (84%) and fever (74%) in infants suffering from rotavirus gastroenteritis was analyzed. The significance of the age on the symptomatology of rotavirus gastroenteritis as well as on the importance of using probiotics has been demonstrated.
