ABSTRACT
Objective To investigate the association between HLA-DRB1 alleles and pemphigus vulgaris (PV) in a Han population in Sichuan.Methods Polymerase chain reaction with sequencespecific primer (PCR-SSP) method was used for low-resolution and high-resolution typing of HLA-DRB1 alleles in 19 patients of Han nationality with PV and 25 healthy controls in Sichuan.Allele frequencies were calculated,and differences in the allele frequency between the above two groups were compared by using chisquare test.Results Totally,9 kinds of DRB 1 low-resolution alleles and 19 kinds of DRB 1 high-resolution alleles were identified in the PV patients and healthy controls.Frequencies of the DRB1* 14 allele (39.47％[15/38] vs.8.00％[4/50],x2 =17.43,P ＜ 0.05) and DRB1*1405 allele (15.79％[6/38] vs.2.00％[1/50],x2 =4.25,P ＜ 0.05) were significantly higher in the PV patients than in the healthy controls.Conclusion The HLA-DRB1*14 allele may be a common susceptibility gene for PV in the Han population in Sichuan,and the HLA-DRB1* 1405 allele may be most closely associated with PV.
ABSTRACT
Objective To investigate the characteristics and the clinical significance of relevant parame-ters of blood in psoriasis vulgaris(PV). Methods A retrospective analysis among 38 PV patients and 40 normal controls was done. The comparing parameters contained NLR,CRP,total cholesterol,triglyceride,serum uric acid.Pearson correlation analysis was used to detect the correlations.Results NLR,total cholesterol,triglyceride, serum uric acid in psoriasis vulgaris patients were significantly higher than in the normal controls(P < 0.05). There was a statistically significant correlation between NLR and PASI in the PV patients,but no correlation of CRP with NLR and PASI(P > 0.05). In the patients with PASI ≥ 7,the serum uric acid level was significantly higher than in those with PASI < 7. Conclusions NLR is indicateive of the severity and state of inflammation. The severer PV,the higher the level of serum uric acid.
