Autoimmune hemolytic anemia.

ABSTRACT

OBJECTIVE: To study the clinico-hematological profile and treatment outcome in children suffering from auto immune hemolytic anemia (AIHA). METHODS: Twelve children were diagnosed with auto immune hemolytic anemia over a period of four years. Direct antiglobulin test was positive in all the cases. Other causes of hemolytic anemia like thalassemia syndromes, hereditary spherocytosis, G6PD deficiency were excluded by appropriate tests. The children were followed up for 6 months to 4 years. RESULTS: The age ranged from 7 mth to 9 yr with a mean age of 4.51 yr. All patients had pallor as the presenting complaint followed by splenomegaly (83.3%), jaundice (66.7%), fever (50%) and bleeding manifestations (16.7%). 9 patients had primary disease and 3 had secondary disease. Tubercular infection was seen in 2 patients with secondary disease. Jaundice was seen equally in both the groups. Oral prednisolone produced remission in 83.3% cases. 4 patients (3 in primary and one in secondary group) had relapse after initial response. All responded to a second course of steroids but had subsequent relapses and developed a chronic course. CONCLUSION: Autoimmune hemolytic anemia is an uncommon cause of hemolytic anemia in children. Tubercular infection is an underlying pathology in cases of secondary autoimmune hemolytic anemia. Although oral steroids induce remission in most of the cases, relapses are common.
