Abstract:
Objective:To analyze the clinical characteristics of nail involvement in patients with pemphigus and the correlation between nail damage and the severity of pemphigus.Methods:The clinical data of 23 patients with pemphigus combined with nail damage admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from January 2011 to August 2019 were retrospectively analyzed, the manifestations of pemphigus combined with nail damage were summarized. The nail damage number of patients with pemphigus complicated with nail damage of different genders were analyzed, as well as the distribution of nail damage in nail and toenail. The titer of anti-desmocoglycoprotein(dsg) antibody was detected in all patients. The relationship between nail damage and disease severity and course in pemphigus patients was analyzed.Results:A total of 132 damage nails were found in 23 patients (14 males and 9 females) with pemphigus, including 66 nails in male, 66 nails in female, 82 nails and 50 toenails. There were 10 forms of nail damage, of which chronic paronychia was the most common. The number of damage nails between different genders in pemphigus patients was statistically significant (χ 2=9.183, P<0.001). The distribution of nail and toenail damage in pemphigus patients was statistically significant (χ 2=10.880, P<0.001). Of the 23 patients, only 3 were positive for dsg1 and 1 was positive for dsg3. There were 19 patients with both positive for dsg1 and dsg3. The titers of dsg1 and dsg3 were compared in 14 patients before and after nail damage. The results showed that the titers of anti-dsg antibody in pemphigus patients after nail damage were significantly higher than before. Thirteen of the 23 patients had nail damage at the time of the initial onset of pemphigus. The nail damage occurred from 6 weeks before the onset to 4 weeks after the onset. The nail damage occurred in 10 patients when the disease recurred. The nail damage occurred within 4 weeks before or at the same time with the blister. Conclusions:The number of damage nails per capita in female patients with pemphigus and nail damage was significantly higher than that in male patients, and nail damage was more common. The titers of anti-dsg antibody will be at a high level when pemphigus patients with nail damage, and the condition gets worse. Nail involvement is positive to the severity of the disease, and it can prolong the time of disease.
