Polyglandular autoimmune syndrome type III accompanied by common variable immunodeficiency
1Department of Endocrinology and Metabolism, Dicle University, School of Medicine, Diyarbakir, Turkey.
Summary
Polyglandular autoimmune syndrome type III and common variable immunodeficiency rarely coexist. This case highlights a unique presentation of PGA type III in a patient with CVID, suggesting a potential link via autoimmunity and HLA association.
Area of Science:
- Endocrinology
- Immunology
- Genetics
Background:
- Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by impaired antibody production.
- Polyglandular autoimmune (PGA) syndrome type III involves autoimmune thyroid disease with other endocrine autoimmune conditions, excluding adrenal disease and hypoparathyroidism.
- The coexistence of CVID and PGA is rare, with limited documented cases.
Observation:
- A 24-year-old female nurse presented with a history of membranoproliferative glomerulonephritis at age 15.
- Clinical and laboratory findings indicated PGA syndrome type III, including hypergonadotropic hypogonadism, insufficient growth hormone response, and thyroid autoimmunity.
- The patient did not exhibit adrenal disease or hypoparathyroidism.
Findings:
- The patient was diagnosed with PGA syndrome type III.
- This case represents a rare coexistence of PGA type III and CVID.
- No prior Medline reports documented this specific co-occurrence.
Implications:
- The co-occurrence of PGA type III and CVID may stem from shared autoimmune mechanisms.
- Human leukocyte antigen (HLA) associations might play a role in the simultaneous manifestation of these conditions.
- Further research is warranted to elucidate the underlying pathophysiology and potential genetic links between CVID and PGA syndrome.
