Aim:
To assess the response to immunosuppressive therapy (IST) in children with acquired aplastic anemia (AAA) and factors affecting the outcome.
Methods:
Ambispective observational study was conducted from Aug 2022 to May 2024 prospectively. Records from June 2012 to July 2022 were analyzed for retrospective cases. Children 2-18 years meeting Camitta's criteria were included. Hematopoietic stem cell transplant (HSCT) was advised if feasible and affordable, rest were offered IST. They received IST with horse anti-thymocyte globulin (ATG) and cyclosporine. Thrombopoietin (TPO) agonists were used in few patients only. Response was assessed at 3 months and 6 months after IST.
Results:
Among 52 prospective cases 43 (83%) were AAA and 9 (17%) were Fanconi anemia (FA). Among 48 retrospective cases, 42 (87%) were AAA and 6 (12%) were FA. FA patients were excluded from analysis. Majority of patients were severe aplastic anemia (SAA) (37%) followed by very severe (VSAA) (32%) and non-severe aplastic anemia (NSAA) (30%). Overall response rate (ORR) was 58.8% with complete response (CR) of 35.3% and partial response (PR) of 23.0% in prospective group and CR of 55.2% and PR of 3.8% in retrospective group. SAA and NSAA patients responded 2.5 times better than VSAA patients to IST (RR = 2.514, 95% CI = 1.145-7.076). Other variables age, gender, duration of illness, duration from diagnosis to IST and type of IST had no correlation with outcome (P > 0.05).
Conclusion:
The ORR was found to be 58.8%, which is similar to published reports.
