Abstract: INTRODUCTION: Fluid leakage is the hallmark of dengue shock syndrome. It is important to identify clinical and biochemical parameters which predict duration and degree of fluid leakage in dengue. METHODS: 102 patients with confirmed dengue were prospectively followed up for clinical, haematological and biochemical parameters, and they were correlated with ultrasonographic evidence of third space fluid accumulation (TSFA). RESULTS: Of the 102 patients (52 males; mean age 28.3 years(SD=11.8), TSFA was detected in 34/95(36%) after hospital admission; 33/95 had pleural effusions which included all except one of 21/95 who had ascites. 72.7% pleural effusions lasted 3 or more days and 52.4% ascites lasted less than 3 days. Duration of pleural effusion showed a significant positive correlation with maximum percentage rises of PCV (r=0.526,p=0.001) and Hb(r=0.525, p=0.001) and negatively correlated with WBC count (r=-0.361, p=0.020) and platelet count (r=-0.585, p=0.000). There was no correlation with any of the other parameters. The mean lowest WBC count of 3005/mm3that was recorded for patients who developed bilateral pleural effusions (n=21) was significantly less (p=0.042) than the mean lowest WBC count of 4091/mm3 that was detected for unilateral effusions(n=12). Duration of ascites was significantly positively correlated with highest AST(r=0.598, p=0.002) and highest ALT(n=0.721, p=.001. CONCLUSIONS: Maximum percentage rise of Hb and PCV, lower WBC and platelet counts seem to be associated TSFA. Among these, lower WBC counts appear to be more predictive of the degree of fluid leakage. Higher ALT and AST levels seem to be useful in predicting the duration of ascites.
