Dengue fever clinico-pathologic correlations and their association with poor outcome.
Professional Med J Jan ;18(1):57-63.

Material & Methods: This prospective study was conducted on 106 seropositive cases of dengue fever. Patients were taken from Abbasi Shaheed Hospital, Karachi from June 2008 to March 2009. Results: The most common hematological abnormalities were thrombocytopenia and leucopenia. Platelets count below 50 - 103/ μL was seen in (78%) cases and 49 % patients had total white cell count below 4 -103 /μL. Partial thromboplastin time was significantly prolonged in (26%) cases whereas prothrombin time was normal in all patients. Liver enzymes both Aspartate Aminotransferase (AST) and Alanine Amino-transferase were significantly elevated in (60%) patients. Blood urea nitrogen (BUN) and creatinine was deranged in (23%) patients. Conclusions: Fever was the most common clinical presentation( 86 % of the patients). Hematological parameters (low platelet count, low total leucocytes count, prolonged APTT and raised hematocrit) and biochemical parameters (raised aminotransferases, blood urea nitrogen) have strong association with the complications of dengue fever and hence are associated with the poor outcome of disease.
