Class I human leucocyte antigen (HLA)-B51 is well known to be associated with Behcet's disease in many ethnic groups. However, there has been no published paper with respect to its association with HLA class I and class II among the Turkish people who live in the eastern region of Turkey. Moreover, as it is known that B51 antigen is encoded by 21 alleles, B*5101-5121, HLA-B51 allele typing was performed, as well as HLA class I and class II genotyping of 75 patients with the disease and the 54 individuals in the matched control group. The result shows that the HLA-B51 frequency was significantly higher (58.66%) in the patient group, compared to that in the control group (18.51%) (OR = 6.245). In the subtyping of B51 alleles, 44 B51-positive patients possessed B*5101 (45.5%), B*5108 (25%), B*5105 (9.1%) and B*5104 (4.5%). There was no significant difference in the HLA-B51 allelic distribution between the patient group and the control group. However, homozygous carriers of HLA-B51 showed considerably high risk (OR = 2.647) in the patient group, compared to that in the control group. In the genotyping of class II HLA alleles, while HLA-DRB1*04 (45.3%) and HLA-DRB1*07 (24%) were the predominant alleles in the patient group, DRB1*11 (50%) appeared to be more common in the control group.
Our 42-year-old patient had comedonal Darier's disease (DD) on the face, comedonal cornifying DD on the upper back, and hypertrophic DD on both legs. Biopsies taken from face, upper back and medial sides of the legs were found to be compatible with these clinical subtypes. The comedonal type was in the classical place, but the hypertrophic and cornifying types were not in the usual sites. In addition to the classic histopathology of DD, we noted multiple, warty dyskeratoma-like structures in the comedonal type, marked compact hyperkeratosis in the cornifying type, and marked papillomatosis in the hypertrophic type.
Omentin serum levels were determined to be low in patients with psoriasis. No significant difference was found regarding Val109Asp polymorphism of the omentin gene. To the best of our knowledge, our study is the first clinical study to examine the relationship between psoriasis and omentin in terms of serum and genomic levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
