Vitamin D, together with its nuclear receptor (VDR), plays an important role in modulating the immune response, decreasing inflammatory process. Some polymorphisms of VDR gene, such as BsmI (G>A rs1544410), ApaI (G>T rs7975232) and TaqI (T>C rs731236) could affect stability mRNA transcription activity, while FokI T>C (rs2228570) gives a truncated protein three fewer amino acids more efficiency binding vitamin D. This study evaluated these four immunopathogenesis leprosy 404 patients 432...

We report an uncommon presentation of bullous dermatosis by linear IgA. There are few cases reported in the literature with this form starting mucosal lesions and then evolving into a similar pemphigoid pattern. In addition, we emphasize importance direct immunofluorescence for definitive diagnosis.

Leprosy is a chronic disease and also global health issue, with high number of new cases per year. Toll-like receptors can respond to mycobacterial molecules in the early stage infection. As important components innate immune response, alterations genes coding for these may contribute susceptibility/protection against diseases. In this context, we used case-control study model (183 leprosy vs. 185 controls) investigate whether patients control group, southern Brazil, have different...

Abstract We evaluated the influence of IL8 T‐738A (nonidentified rs), T‐353A (rs4073), IL17A G197A (rs2275913), and IL17F T7488C (rs763780) single‐nucleotide polymorphisms on leprosy. The AA genotype was observed as a risk factor for multibacillary leprosy, regardless gender age‐of‐onset disease, considering recessive model (OR, 3.8; 95% CI, 1.1–13.5; P , 0.023). Furthermore, associated with leprosy type 1 reaction 2.4; 1.1–5.1; 0.026) when compared to group without reaction, which adjusted...
