Abstract
The goal of this study is to investigate the impact of the rs35829419 SNP on the serum level of NLRP3, and to assess the relationship between NLRP3 and its SNP and vulnerability to Pityriasis versicolor. Pityriasis versicolor (PV) is one of the most frequent skin conditions linked to skin pigmentation changes. Malassezia plays a key role in the pathogenesis of PV. A case-control study, 50 patients with pityriasis versicolor and 44 healthy controls. Real-time PCR was used to genotype NLRP3 (rs35829419) and ELISA assay of NLRP3 levels in tissue samples. There was a significantly higher median NLPR3 levels in PV patients than controls. A significant predominance of A allele of Q 705K was in patients than controls. The risk of having the disease in the presence of A allele is nearly 10 times than having C allele. In PV patients, there was a significant relationship between NLPR3 levels and Q 705K genotypes with higher NLPR3 levels in AA genotype. A potential correlation between PV and the Q705K polymorphism, pointing to evidence of NLRP3 alteration in PV patients. The NLRP3 inflammasome may be an appropriate therapeutic target for Malassezia-associated skin disorders.
