Clinical profile of anti-NXP-2 antibody-positive inflammatory myositis and outcome in an Indian population

ConclusionThe current study shows that adult DM patients with anti-NXP-2 autoantibodies have a unique clinical phenotype. Its presentation differs between adult and JDM, even in different parts of the world. Muscle weakness is mild and responds to treatment. Dysphagia needs more time and aggressive IS for improvement as compared to other muscle involvement.Key Points• Anti-NXP-2 antibody presentation varied from adult to child, as in different parts of the world.• In Indian adult patients, non-specific skin manifestations were more common, whereas in JDM, specific skin features were common.• There was less likely involvement of the lung and heart. But more risk of GI involvement requiring aggressive management.• Adult with anti-NXP-2 antibody should be screened for malignancy at the time of presentation.
