Abstract

Background: Blood transfusion saves millions of life in emergency situations and is considered has life saving drug. Blood transfusion is associated with several risks which also includes transfusion transmissible infections. With the implementation of strict donor selection, effective and sensitive screening tests can ensure the least reduction risk of acquiring transfusion transmissible infections. The prevalence of transfusion transmissible infections among blood donors reflect the burden of diseases among particular population. Aim: The aim of this study is: 1. To estimate the prevalence of transfusion transmissible infections among blood donors in a rural tertiary care centre; 2. To analyse the trends of transfusion transmissible infections over study period. Results: A total of 21,089 voluntary blood donors were studied. There were 20,356 male donors and 733 female donors with ratio of 28:1. The prevalence of HIV, HBV, HCV, Syphilis and Malaria was found to be 0.14%, 0.82%, 0.02%, 0.13% and 0.03% respectively. The prevalence of HBV was highest (0.82%) followed by HIV(0.14%). Our study also showed decrease in trends of HCV and Syphilis over study period. There was strong association of transfusion transmissible infections among O positive blood group. Conclusion: The prevalence of transfusion transmissible infections has decreased over time, hence implementation of strict donor selection criteria and use of sensitive screening tests has lead to decrease in trends.

Abstract

Introduction: Dengue is an arboviral disease endemic in India. Severe dengue has a high morbidity. The progression to severe dengue may be diagnosed by clinical and lab parameters, are of the useful lab tests is platelet count, as thrombocytopenia is a consistent feature in dengue. There is confusion about the role thrombocytopenia in dengue. Our study aims to study the platelet count patterns and its relevance to severity of dengue. Materials and Methods: We conducted a study on 132 dengue positive cases with relevant hematology data in November 2016. Results: We had predominance of young people and males in the study group. Thrombocytopenia was uniform across the ages and sexes. Severe thrombocytopenia constituted 56%, had significant association with atypical lymphocytosis, rise in hematocrit and antibody patterns. Conclusion: Platelet counts are marker of dengue, can serve as predicators of severity, platelet count monitoring helps guide transfusion therapy. Keywords: Dengue, Platelet count, Total count, Differential count, Hematocrit, Serology.
