26588

Objectives: In this study we investigated the anti-HAV IgM positivity rates and their distribution according to age and season of a year in Van region of Turkey. Materials and methods: During five-year period between 2006-2010, the presence of anti-HAV IgM were determined in the serum samples sent to our laboratory that have prediagnosis of hepatitis A by ELISA test, using AxSYM (Abbott Diagnostics, Germany) and i2000SR Architect (Abbott Diagnostics, Germany) analyzers. For statistical analyze of Anti-HAV IgM positivity rates, patients’ age and gender and time of year when specimen was obtain were compared. Results: The presence of anti-HAV IgM was investigated in a total of 8851 patients, including 5303 (60%) children and 3548 (40%) adults. Anti-HAV IgM in children and adult patients were determined as 9.8% and 2.6%, respectively, and this difference was found statistically significant (p 0.01). Anti-HAV IgM positivity rate began to rise in August, reached the highest level in November-December and decreased to the initial level in January. The highest frequency detected during the November-December period was statistically significantly higher than rates found during other months. Conclusions: The prevalence of Hepatitis A was found to be similar with previous studies performed in our country. The prevalence of disease was significantly increased especially between November and December.
