AGUDELO, IVONY YIRETH et al. Associated factors to plasma leakage in dengue patients from Antioquia and Chocó between 2000 and 2013. Colombia. CES Med. [online]. 2015, vol.29, n.1, pp.23-24. ISSN 0120-8705.

Introduction: Plasma leakage is the most severe complication caused by dengue virus infection and is also the mechanism that frequently leads to dengue shock syndrome. Plasma leakage is characterized by ascites, pleural and pericardial effusion and increased hematocrit level. The present study was conducted to identify socio-demographic, clinical and laboratory factors that more are associated to the presence of plasma leakage in dengue infected patients. Materials and methods: A cross sectional analytic study was performed on clinical records from dengue infected patients using the casecontrol methodology. Pearson's chi-square test or Fisher's exact test, Mann-Whitney's non-parametric U test and a multivariate logistic regression model of associated factors were used to evaluate the data. Odd Ratios with 95 % confidence intervals were calculated and significance level of 5 % was considered. Results: A total of 350 clinical records were analyzed, 128 cases (36.6 %) presented signs of plasma leakage. After adjustments by confounding factors, we observed that abdominal pain, leukopenia and melena were the variables that explain the presence of plasma leakage in dengue infected patients. Conclusion: During the follow-up of dengue infected patients priority should be given to the survey of these clinical and laboratory findings in order to identify the cases with higher probabilities of developing plasma leakage, allowing achieving more timely and appropriate management.
