We present three new cases of cutaneous polyarteritis nodosa with a follow-up ranging from 38 to 49 months, describing their clinical and histological findings, as well as treatment options leading to sustained remission. All patients met the criteria for di-agnosis. The presence of extracutaneous symptoms and laboratory analysis differed among our patients, as did various elements of the workup in comparison to published studies. We concluded that dapsone alone, or in combination with systemic steroids, proved superior and highly effective despite being less frequently used. More aggressive therapy for shorter intervals could lead to quicker remission of cutaneous lesions and symptoms without chronic relapses, which are commonly noted. © 2021, Slovene Medical Society.

Background: Autoimmune pemphigus is a group of severe blistering diseases. Although corticosteroids have dramatically altered the prognosis of pemphigus, morbidity and mortality resulting from the adverse effects of systemic corticosteroids remain high. Dexamethasone-cyclophosphamide pulse (DCP) therapy was introduced to diminish the adverse effects of prolonged conventional daily dose regimens. Objective: To report our experience with the use of the DCP regimen in patients with autoimmune pemphigus. Methods: In the period 1998-2002, 72 patients with various forms of autoimmune pemphigus treated with DCP therapy were included, of whom 36 patients were previously treated with conventional corticosteroid therapy, and 36 were newly diagnosed patients. Results: Of the 72 patients, 43 completed treatment, while 13 patients did not respond adequately to the treatment and continued with the conventional daily regimen, nine patients were lost to follow-up, and seven patients died. Two of these deaths were probably a consequence of DCP therapy. Conclusion:DCPregimen is a beneficial treatment for patients with pemphigus, sparing the adverse effects of conventional regimens. © 2010 Adis Data Information BV. All rights reserved.

Direct immunofluorescence of peri-lesional skin is the gold standard in the diagnosis of pemphigus. A specific immunofluorescence pattern may also be demonstrated in the outer root sheath of anagen and telogen hair. We demonstrated an intercellular reticular deposition of immunoglobulin G in the outer root sheath of plucked anagen and telogen hair in all pemphigus vulgaris patients with active disease and for the first time in all patients with active pemphigus foliaceus. Moreover, we demonstrated for the first time that plucked hair samples may be kept at -20C for at least 2 weeks before immunofluorescent staining and analysis. © 2013 The Authors.

Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are rare autoimmune blistering diseases with presumed T-cell–dependent pathology. Activation of naïve T cells is dependent on antigen recognition, subsequent signaling through the T-cell receptor complex (signal 1), and various other interactions of T cells with antigen presenting cells that may be collectively designated as signal 2, which is unconditionally required for T-cell activation both in response to infection and to autoantigens. Among the best described interactions contributing to signal 2 are those mediated by B7 family molecules, such as CD80 and CD86 with their ligands; CD28, providing activation signals; and cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4), conferring inhibition. Single nucleotide polymorphisms (SNPs) within genes encoding those molecules may alter the signaling process. It is not known whether functional genetic polymorphisms within genes encoding the aforementioned proteins may increase risk for developing PV and PF and, if so, whether they might serve as biomarkers for susceptibility to these diseases. To address those questions, we examined functional single nucleotide polymorphisms within CD86 (rs1129055) and CTLA4 (rs733618 and rs5742909) genes in 61 pemphigus patients and 486 healthy controls. We found statistically significant differences in allele and genotype frequencies between PV patients and controls for rs1129055, as well as for rs5742909 among PV and PF patients. Namely, the rs1129055 A allele was significantly more common in PV patients compared with controls (35.4% versus 25.7%, respectively; P = .040), whereas the rs5742909 T allele was significantly more common in PF compared with PV patients (19.2% versus 5.2%, respectively; P = .035). The frequency of the rs5742909 T allele did not, however, differ significantly in PF or in PV compared with controls (10.5%; P = .187 and P = .100, respectively). We report a novel association of SNPs within CD86 and CTLA4 genes with pemphigus. The CD86 rs1129055 A allele appears to confer susceptibility to PV but not to PF. © 2016 Elsevier Inc.

We present a patient with a 33-year history of poikilodermatous mycosis fungoides (MF) who subsequently developed CD30-positive large cell transformation. After 6 years of conventional MF treatment, side effects of therapy and/or concomitant diseases prevented the previously applied treatment modalities. The CD30-directed antibody-cytotoxic drug conjugate (brentuximab vedotin) was introduced and followed by quick and excellent therapeutic response. © 2019 Wiley Periodicals, Inc.
