Pemphigus Vulgaris and Pemphigus Foliaceus: Differences in Epidemiology and Mortality.

The objective of this study was to compare PV and PF patients regarding ethnic variations and mortality rates. Mortality of PV and PF patients was compared with age- and gender-matched control subjects in the general population. The study cohort comprised 207 patients with PV and 30 with PF diagnosed during the period 2000 to 2015. The incidence rate of PV among Jews was 3.6-fold higher than among Arabs (p

Authors: Gualtieri B, Marzano AV, Grando S Abstract In this review, we recap current knowledge about non-desmoglein autoantigens in atypical forms of autoimmune pemphigus. More than 50 keratinocyte proteins, including adhesion molecules, receptors and enzymes as well as mitochondrial proteins can be targeted, leading to alterations in numerous intracellular signaling pathways. Patients with pemphigus herpetiformis feature various combinations of antibodies to desmogleins 1 and 3 and desmocollins 1-3. Pemphigus vulgaris patients who do not have antibodies to desmogleins develop typical clinical and histological feat...

Infections were the primary cause of death (34.3 –55.5%) in patients with pemphigus. Skin was usually the origin of infections. The study aimed to explore features and associated factors of bacterial skin infec...

Authors: Maglie R, Antiga E, Payne AS Abstract Pemphigus is a rare autoimmune disease of the skin, characterized by autoantibodies targeting adhesion proteins of the epidermis, in particular desmoglein 3 and desmoglein 1, that cause the loss of cell-cell adhesion and the formation of intraepidermal blisters. Given that these autoantibodies are both necessary and sufficient for pemphigus to occur, the goal of pemphigus therapy is the elimination of autoreactive Bcells responsible for autoantibody production. Rituximab, an anti-CD20 monoclonal antibody, was the first targeted B-cell therapy approved for use in pemphi...

Conclusions: PTX3 was found to be increased in PV and PTX3 could be a useful indicator of disease activity in PV. PMID: 32994770 [PubMed]

Pregnancy may induce the onset or exacerbation of autoimmune bullous diseases such as pemphigus or pemphigoid gestationis. A shift toward T helper (Th) 2 immune response and the influence of hormonal changes have been evoked as possible triggering factors. Therapeutic management of this setting of patients may represent a challenge, mainly due to safety concerns of some immunosuppressive drugs during pregnancy and lactation. In this narrative review, we provided a comprehensive overview of the therapeutic management of autoimmune bullous diseases in pregnant and breastfeeding women, focusing on pemphigus and pemphigoid gestationis.

Discussion Syphilis is caused by the spirochete Treponema pallidum. It is a very old disease that despite understanding the organism and readily available treatment, still causes disease. Syphilis is transmitted sexually. According to the Centers for Disease Control, “[i]n 2018, a total of 35,063 cases of [Primary and Secondary] syphilis were reported in the United States, yielding a rate of 10.8 cases per 100,000 population …. This rate represents a 14.9% increase compared with 2017 (9.4 cases per 100,000 population), and a 71.4% increase compared with 2014 (6.3 cases per 100,000 population).” The incre...

This study aimed to evaluate the effect of repeated rituximab courses on remission length in pemphigus vulgaris. A total of 73 patients with pemphigus vulgaris treated with rituximab at a single centre were retrospectively analysed. Of 73 study participants (28 men, 45 women), 42 (58%) received a 2nd course of rituximab, 24 (33%) received a 3rd course, 4 (6%) received a 4th course, and one (1%) received a 5th course. Rituximab remained efficacious in each course, irrespective of previous treatments (complete remission 75-81%). Following the 2nd and 3rd courses, the results indicated longer remissions with reduced flare-ups...

Discussion Oral ulcers are common problems seen by dentists but pediatricians also see them. Usually families have are concerned because they are painful and acute. Ulcers are sometime noticed by the physician and not the family as in the case of herpangina or hand-foot and mouth disease. Chronic or recurrent ulcerations present less commonly and therefore it may be more difficult to determine their etiology. Many of the systemic disease causes of oral ulcers are overall infrequent and/or not common in the pediatric age range. Ulcers can be classified in several ways but acute ulcers are usually painful and last less tha...
