Abstract
Alopecia areata (AA) is a skin condition in which hair is lost from certain or all areas of the body. This condition has been described as an immune-mediated complex genetic disease, characterized by the presence of lymphocytes that are directed to the hair follicles in the anagen phase. The gene encoding the protein tyrosine phosphatase, non-receptor type 22 (PTPN22), which is exclusively expressed in immune cells, has been considered as a risk factor associated with a number of autoimmune diseases. In AA, the single nucleotide polymorphism, rs2476601, has been identified as a risk factor in several populations. The aim of the present study was to investigate the effect of PTPN22 C1858T inherited genetic polymorphism on the predisposition to severe forms of AA, in a case-control study on individuals. The study included 64 unrelated patients diagnosed with several types of AA, as well as 225 healthy unrelated subjects. The DNA samples were genotyped for PTPN22 C1858T polymorphism using the polymerase chain reaction-restriction fragment length polymorphism technique. Causal associations were determined by χ2 test and their respective odds ratio (OR) was assessed in a 2×2 contingency table. The results demonstrated a significant association of the T allele [P=0.040; OR=3.196; 95% confidence interval (CI), 0.094-10.279] and the CT genotype (P=0.038; OR=3.313; 95% CI, 1.008-10.892) with patchy AA. In conclusion, the results of the present study suggested the possible involvement of the T allele of the PTPN22 C1858T SNP as a genetic risk factor for this type of AA in the population studied.

Abstract
OBJECTIVES The aim of this research was to describe the cases of TNF-α antagonist-related alopecia reported in the French Pharmacovigilance Database (FPVD) and to investigate the association between exposure to TNF-α antagonists and occurrence of alopecia. METHODS All spontaneous reports of TNF-α antagonist-related alopecia recorded in the FPVD between January 2000 and April 2012 were colligated and described. We conducted disproportionality analyses (case/non-case method) to assess the link between the occurrence of alopecia and exposure to TNF-α antagonists. Cases were all reports of alopecia and non-cases were all other reports recorded during the study period. Exposure to TNF-α antagonists was sought in cases and in non-cases. Reporting odds ratios (RORs) were calculated to assess the association. Docetaxel was used as positive control and acetaminophen as negative control. We performed sensitivity analyses excluding cases of androgenic alopecia and those occurring in psoriatic patients. RESULTS Among 282 590 spontaneous reports of adverse drug reactions (ADRs) collated in the FPVD, 1068 cases (alopecia reports) were identified. Of these cases, 52 (4.9%) occurred during exposure to TNF-α antagonists (18 involved infliximab, 17 adalimumab, 15 etanercept and 2 certolizumab). Exposure to TNF-α antagonists was more frequent among alopecia reports than among other ADR reports for all TNF-α antagonists pooled (ROR 3.0, 95% CI 2.3, 4.0) as well as for each antagonist separately, with similar values. Sensitivity analyses yielded similar results. The RORs were 29.9 (95% CI 25.3, 35.5) with docetaxel and 0.3 (95% CI 0.2, 0.4) with acetaminophen. CONCLUSION The present study confirms a strong link between TNF-α antagonist exposure (class effect) and the occurrence of alopecia.
