Clinical Profile and Severity of Hemolysis in Adult Patients of Primary Autoimmune Hemolytic Anemia and Their Response to Steroid: A Prospective Cohort Study from Single Institution

This study on patients of adult primary AIHA was conducted by taking complete history followed by detail physical examination. Laboratory investigations were performed to establish haemolytic anaemia and to assess severity of haemolysis. Immunehematological work up including blood grouping, direct antiglobulin test (DAT), IAT, antibody screening, adsorption elution was performed to diagnose type of AIHA. All cases were followed up to assess the response to prednisolone. All the data were collected and analysed by SPSS 19. Out of 62 primary AIHA cases, female were affected more than male (41:21). WAIHA is most common type (42, 67.8%) followed by mixed (20.9%) and cold AIHA (11.3%). Severity of haemolysis showed significant correlation with the DAT strength and not with type of AIHA. (P <  0.05) On oral prednisolone, 22 cases attended complete remission, while relapse, drug dependency and partial remission was achieved in 13, 9, 3 cases respectively. Severity of haemolysis in AIHA is directly related with DAT strength. WAIHA is most common type and can be managed with oral predniso lone (cr 45.2%), without red cell transfusion in most of cases. Mixed type AIHA cases were presented mostly with severe haemolysis, with minimum therapeutic response to prednisolone and maximum relapse/drug dependency.
