Abstract
Introduction: Autoimmune haemolytic anaemia (AIHA) is an autoimmune disorder that can present in primary or secondary forms. The literature looking at impact of baseline fluorescent antinuclear antibody (FANA) positivity on outcomes of AIHA patients is infrequent. Objective: To study the impact of baseline FANA positivity in patients with primary AIHA. Method: A prospective cohort study involving 29 consecutive primary AIHA patients presenting to the Haematology department from 2013 to 2015 was analysed. After recording baseline investigations including fluorescent ANA, all patients were treated as per the standard therapeutic protocols. Clinical remission, disease free survival, relapse, mortality were compared between the FANA positive and FANA Negative AIHA groups. Results: Baseline FANA positivity was found in 17 patients (58.62%). Both the groups were comparable in terms of age, sex, Hemoglobin, LDH at presentation, number of lines of treatment needed and duration of follow up. Evan's syndrome was seen in six of FANA positive patients which was statistically significant (0 v/s 6, p = 0.023). FANA positive patients had significantly higher rates of relapse per patient month follow up (1.22 v/s 3.57, p = 0.023) and lower rates of complete response (83.33% v/s 35.29%, p = 0.0118) and relapse free survival at five years. Morbidity and mortality were numerically higher in FANA positive patients. Conclusion: Baseline FANA positivity among AIHA patients was found to be associated with lower complete response rates and higher relapse rates with possible higher rates of morbidity. Presence of FANA will give us prognostic value and help us in deciding the treatment options.
