Abstract:
A case of familial pemphigus vulgaris is described in an uncle and his niece who developed the disease 18 years apart. The man died from pemphigus in 1964. The diagnosis was confirmed histopathologically in both cases, but immunofluorescent microscopic studies were performed only in the woman because the technique was not available in 1964. HLA typing in the woman and her daughter and sister showed A 26, BW 38 and DRW 4 in all of them. Clinical disease did not develop in the other family members.
Insights
This study describes a rare familial case of pemphigus vulgaris in an uncle and niece. Genetic analysis revealed shared HLA types in affected family members, suggesting a potential genetic predisposition to this autoimmune blistering disease.
Area of Science:
- Dermatology
- Immunogenetics
- Autoimmune Diseases
Background:
- Pemphigus vulgaris is a rare autoimmune blistering disease.
- Familial occurrence of pemphigus vulgaris is exceptionally uncommon.
- Understanding the genetic factors in autoimmune diseases is crucial for diagnosis and treatment.
Observation:
- A case of familial pemphigus vulgaris is presented, involving an uncle and his niece who developed the condition 18 years apart.
- The uncle passed away from pemphigus in 1964.
- Histopathological confirmation was obtained for both individuals.
- Immunofluorescent microscopic studies were conducted on the niece, but not the uncle due to the unavailability of the technique in 1964.
Findings:
- Human Leukocyte Antigen (HLA) typing was performed on the affected niece, her daughter, and her sister.
- All three individuals shared the HLA types A26, BW38, and DRW4.
- No other family members developed clinical symptoms of the disease.
Implications:
- The shared HLA types among affected family members suggest a potential genetic susceptibility to pemphigus vulgaris.
- This case highlights the importance of considering familial and genetic factors in the etiology of pemphigus vulgaris.
- Further research into HLA associations could aid in identifying individuals at risk and developing targeted therapies for pemphigus vulgaris.
