INTRODUCTION AND OBJECTIVES: As well as increased susceptibility to infections, autoimmune and inflammatory manifestations also eventuate due to dysregulation of immune system in a substantial proportion of patients with primary immunodeficiency (PID). Autoimmune and inflammatory manifestations can occur prior or after diagnosis of PID. This study aimed to evaluate autoimmune and inflammatory complications among all types of PID patients in childhood and to emphasize the importance of these findings as a warning sign to diagnose PIDs.
METHODS: Medical records of 1036 patients with PID, followed up between 2003 and 2019, were retrospectively screened for occurrence of autoimmunity and inflammation. During this time, demographic features, autoimmune/inflammatory findings and initial time, genetic mutations, laboratory and clinical follow up findings, treatment regimens and outcomes were recorded.
RESULTS: Autoimmune and inflammatory manifestations were observed in 83 patients (10.1%). The median age of autoimmunity initial time was 61.3±53 months. Sixty-seven (80.7%) patients presented with autoimmune and inflammatory manifestations, and these findings had occurred during 16 patients' (19.3%) follow-up. The most common autoimmune manifestations were autoimmune hematologic (51.8%) and endocrine diseases (26.5%). Fifty patients (60.2%) had a single autoimmune/inflammatory manifestation, however 23 patients (27.7%) had two, eight patients (9.6%) had three and two patients (2.4%) had four different types of autoimmune/inflammatory manifestations. The frequency of autoimmune and inflammatory manifestations in phagocyte defects (56%), combined immune deficiencies (53%) and immune dysregulation diseases (52%) were observed higher than other forms of PIDs. During follow-up 13 (15.7%) patients died.
CONCLUSION: Autoimmune/inflammatory manifestations are associated with high morbidity in patients with PIDs and may precede the diagnosis of PID in childhood. Therefore, physicians must be aware of underlying possible immune deficiency and patients with known PIDs should be evaluated for autoimmune and inflammatory complications.
