Summary
Pemphigus vegetans (P Veg) is a rare autoimmune disease. This study found P Veg may be more common in Tunisia, with a high mortality rate, though more research is needed.
Area of Science:
- Dermatology
- Autoimmune Diseases
- Clinical Research
Background:
- Pemphigus vegetans (P Veg) is a rare variant of pemphigus, with limited published research.
- Prognostic factors for P Veg have not been previously evaluated.
Purpose of the Study:
- To analyze epidemiological, clinical, immunopathological, and therapeutic data for Pemphigus vegetans.
- To investigate prognostic factors and patient survival accuracy in P Veg.
Main Methods:
- Retrospective study of 17 P Veg cases from 1981-2009.
- Statistical analysis using chi-square, Fisher, and log rank tests.
- Kaplan-Meier methods for survival analysis.
Main Results:
- P Veg prevalence was 0.084‰, comprising 9.1% of pemphigus cases.
- Mean age at onset was 47.6 years; female predominance (4.66:1). Neumann variant was most common.
- Median relapse-free survival was 13 months; 3 deaths and 11 relapses occurred during follow-up.
Conclusions:
- Pemphigus vegetans appears more prevalent in Tunisia.
- A high mortality rate associated with P Veg was observed.
- Limitations include a small patient cohort and retrospective design.
