Abstract
BACKGROUND
Pemphigus vulgaris belongs to a group of rare, autoimmune, blistering disorders, requiring intensive immunosuppressive therapy. Lung infections are common in patients with pemphigus vulgaris.
OBJECTIVE
To evaluate pulmonary function in patients with pemphigus vulgaris, in order to detect possible factors that might predispose PV patients to lung damage.
METHODS
Ten patients first diagnosed with severe pemphigus vulgaris and 10 healthy individuals,were included in the study. Pulmonary function testing, blood gas analysis and quantification of α1-antitrypsin serum levels were performed.
RESULTS
Mild reduction of CO diffusing capacity was recorded, compared to the mean predicted normal value. DLCOSB (single-breath carbon monoxide diffusing capacity test) values did not significantly differ between patients with pemphigus vulgaris and healthy controls, while differences regarding DLCO/VA (VA: Alveolar Volume) were statistically significant. Alpha 1-antitrypsin serum levels were decreased (<2.0g/L) in 60% (6/10) of patients with pemphigus vulgaris and were found normal in none of the healthy controls.
CONCLUSION
A mild reduction of pulmonary diffusing capacity was observed in patients with pemphigus vulgaris.
