Abstract


Objectives: To estimate the range of hepatic involvement in dengue infections by assessing clinical and biochemical profile of adult dengue infected patients.

Methods: Serologically confirmed 220 adult cases of dengue infections admitted to Mayo hospital from June 2013 to November 2013 were classified as having dengue fever, dengue haemorragic fever and dengue shock syndrome. The frequency and range of bilirubin, liver enzymes derangement and presence of liver enlargement in each group was calculated and further stratified according to age and gender. Patients with positive viral serology, chronic liver disease, malaria and typhoid were excluded from the study.

Results: About  60% of DHF patients had hepatomegaly compared to 40% of DF patients. Liver dysfunction was more common in DF compared to DHF (38.15 vs 18.6%). Hyperbilirubinemia was noted in 40 (18.2%) patients, 28 (12.7%) in DF and 12(5.5%) in DHF. The mean serum bilirubin was higher in DHF [0.87+0.33] compared to DF [0.74+0.27]. Bilirubin was higher in male patients and in younger (<20 years) age group. ALT was elevated more frequently in male patients in age group of 31-40 years and in DF patients as compared to DHF [72(32.7% vs 40(18.2%)]. The mean serum ALT level was 103.7 U/l in DHF and 69.2U/l in DF. AST was raised in all DHF patients as compared to DF in which 40% patients had normal AST levels. Alkaline Phosphate was high in all DHF patients with a mean of 278.7. It was raised in most of the DF patients as well and majority of patients were in age group of 31-40 years.

Conclusion: Liver involvement is very common in dengue infections and is not limited to elevation of transaminases only. Bilirubin and Alkaline phosphatase are also raised in considerable number of patients. Therefore in adults with fever, jaundice, hepatomegaly and altered liver function tests, the diagnosis of dengue infection should be strongly considered in areas where dengue infection is endemic.
