Pemphigus is an autoimmune bullous disease that causes the development of blisters and erosions on the skin and/or mucosa. Its inflammatory process is mediated by cytokines, which interact with sleep in a bidirectional manner. Pain, a frequent symptom due to pemphigus lesions, is well known to impair sleep quality. Depression is also associated with pemphigus and pro-inflammatory cytokines and may impair sleep. Additionally, a common relationship among other dermatological diseases and sleep has increasingly been described...

Paraneoplastic pemphigus (PNP) is an autoimmune bullous disease associated with underlying neoplasms, both malignant and benign. The most constant clinical presentation of PNP is the presence of intractable stomatitis. Herein we present a 25-year-old male with a 3-month history of refractory stomatitis especially involving the lips and widespread vesiculobullous eruption on his trunk and extremities. The diagnosis of PNP was confirmed based on histological and serological results. Investigation for the underlying neoplasm revealed a retroperitoneal tumorous mass which was biopsied and diagnosed as the inflammatory myofibroblastic tumor (IMT)...

A 46-year-old woman with a 30 pack-year smoking history presented with a worsening eruption on the left cheek that failed to improve with metronidazole gel. The cutaneous eruption spread to most of her face and did not respond to a brief tapering course of prednisone. During the initial evaluation at our institution, approximately 6 weeks after the onset of the cutaneous eruption, the patient had erythematous, crusted plaques on her face and scalp (Figure 1A); they were also present on the V-area of the anterior aspect of the neck and upper region of the chest, the shoulders, and the arms, with isolated lesions on the trunk and legs...

Autoimmune bullous diseases (ABDs) are uncommon but significant skin disorders with relatively high morbidity and mortality. Some surveys have been carried out to describe the spectrum of ABDs in a region, but this is the first that has focused on ABDs in elderly patients. This study was conducted to determine the clinicoepidemiologic features of ABDs in elderly patients. Medical records of all ABD patients with disease onset after the age of 60 years who presented to the Autoimmune Bullous Diseases Research Center, Tehran, Iran between April 2003 and March 2013 were reviewed...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

Pemphigus vulgaris (PV) is an autoimmune blistering disease of the skin and mucous membranes. The mean platelet volume (MPV) is an index of platelet activation reported to be influenced by inflammation. We investigated the MPV in patients with PV relative to controls. This case-control study included 160 patients with PV and 640 age- and sex-matched controls. The MPV, platelet count, and other inflammatory parameters were measured for all study participants. A significantly decreased MPV was observed in patients with PV compared with controls, 9...

A range of pemphigus is relatively rare potentially fatal group of autoimmune blistering dermatoses. Usually, there is no apparent triggering, while in some predisposed patients there are alleged environmental/industrial inducing factors. In a short time period (4 years), we diagnosed 3 novel cases of pemphigus (1 pemphigus vulgaris, 1 pemphigus foliaceus and 1 shift from pemphigus foliaceus into pemphigus vulgaris) at a clinical and laboratory level (ELISA, immunofluorescence studies). We discuss a possible common inducing mechanism as these patients inhabit one estate of the Poznan suburbia (Kozieglowy, population < 12,000), Greater Poland district, Poland, and review literature data on alleged pemphigus triggers...

Double-filtration plasmapheresis is an effective and safe treatment for pemphigus. We retrospectively evaluated the decrease in autoantibody titer and pemphigus disease area index following double-filtration plasmapheresis in five patients with moderate to severe pemphigus, who were physically and/or serologically unresponsive to 1.0 mg/kg per day of prednisolone and other supportive drugs and ointments. The percentage reduction in autoantibodies 85.6 ± 14.4% (P = 0.00014), and that in pemphigus disease area index was 75...

Pemphigus vulgaris is a serious autoimmune skin disorder associated with desmoglein 1 and 3. Selective plasma exchange (SePE) for pemphigus vulgaris remains unknown. We investigated the removal characteristics of pemphigus autoantibodies, immunoglobulins, and fibrinogen in three cases. When the mean processed volume for SePE was 1.2 plasma volumes, the mean percent reduction was 50.7% for desmoglein 1, 48.9% for desmoglein 3, 50.3% for IgG, 29.8% for IgA, 1.9% for IgM, and 17.6% for fibrinogen. In one case, the percent reduction after four sessions of SePE within eight days was 87...

Bullous pemphigoid and pemphigus vulgaris, which belong to the group of subepidermal and intraepidermal bullae, respectively, are two potentially devastating blistering skin diseases. We used high-frequency ultrasound (US) in 3 cases of these diseases as prototypes to study the value of high-frequency US in discriminating blister locations. Our findings showed that high-frequency US has a strong correlation with histomorphometric findings because of its high resolution, and we hope that it will be helpful for differentiating blister locations...

Pemphigus is a skin and mucosal membrane-targeting autoimmune bullous disease. Previous studies have demonstrated that circulating anti-desmoglein1/3 antibodies are pathogenic and mediate blister formation. However, the role of infiltrated immune cells in the lesional skin has not been fully investigated. In this study we showed that there existed a large number of B, T lymphocytes and plasma cells in the skin lesions by immunohistochemistry and immunofluorescence staining. In addition, a significantly increased number of Dsg1 and Dsg3-specific B cells could be identified by flow cytometric analysis or ELISPOT assay...

Immunosuppressive drugs are the milestone of treatment of autoimmune diseases, but they can lead to serious complications, including hepatitis B virus reactivation in HBV carriers as well as in patients with occult HBV infection (OBI). A 36-year-old man with OBI was diagnosed with pemphigus vulgaris. He was prescribed prednisolone and his hepatitis B surface antigen turned positive. Viral replication was successfully controlled by lamivudine and adefovir. Mycophenolate mofetil and intravenous immunoglobulin  were not effective in controlling the pemphigus vulgaris...

BackgroundPemphigus foliaceus (PF) is a blistering disorder most commonly presenting in middle age. As PF is restricted to the superficial epidermis, it is considered more benign than other pemphigus diseases. However, progression to severe disease is not uncommon. Although rituximab's efficacy has been well-documented in adults with refractory PF, little data is available on its role in adolescents.PurposeWe describe a patient with juvenile PF treated with rituximab and review the literature for similar cases...

BACKGROUND: Intraepidermal acantholysis is a characteristic histopathological feature of pemphigus. The histopathology of scalp biopsies in pemphigus has not been widely discussed in the literature, although the scalp is commonly involved in pemphigus. METHODS: A total of 32 consecutive patients with scalp involvement (seventeen with pemphigus vulgaris and fifteen with pemphigus foliaceus) were enrolled into the study. The histopathological examination of scalp biopsies was performed in all patients...

Rituximab (RTX) has been used successfully to treat refractory pemphigus. We aimed to assess the response of pemphigus vulgaris (PV) cases to RTX therapy and its effect on CD4(+)CD25(+) (T regulatory) cells level. Sixteen PV patients were included in this study, each received one cycle of two RTX infusions (1000 mg on days 1 and 15). Five PV patients served as controls. All cases were on prednisolone ± adjuvant therapy. Pemphigus disease area index (PDAI), autoimmune bullous skin intensity score (ABSIS), anti-desmoglein antibodies, CD4, CD8, CD20 and CD4(+)CD25(+) levels were assessed at baseline, 3, 6 and 12 months after therapy...
