Background: Recently, rituximab has been successfully used for the treatment of pemphigus family, the main subtype of which is pemphigus vulgaris (PV). The aim of this study was to determine the efficacy and safety of rituximab in refractory PV. Methods: In an observational study extending from November 2014 to February 2016, 30 patients with refractory PV were treated with rituximab. Response to therapy, duration of clinical remission, relapse rate, serology, and side effects of treatment with rituximab were evaluated. Results: At the end of the follow-up with a mean duration of 7.6 (6-14) months, 25 (83.3%) patients achieved complete remission with or without systemic therapy. The mean duration of disease control was 2.8 months. In all patients, the serum levels of antidesmoglein 1 and 3 IgG antibodies were reduced after rituximab therapy. In 23.4% of the patients, a clinical relapse occurred at a mean of 9.6 months following the initiation of the treatment. Infusion-related reactions occurred in 18 (60%) patients. The lack of a control group, concomitant use of corticosteroid and immunosuppressive agents, and a limited follow-up period were among the limitations of our research. Conclusions: Rituximab is a good treatment modality for refractory PV, which extends the mean time to relapse in patients. To further extend our knowledge on the efficacy and safety of rituximab therapy, more randomized controlled trials with larger sample sizes and prolonged follow-up durations are required.

Background: Psoriasis is a chronic disease with multiple biochemical and vascular abnormalities. Several studies have evaluated circulating levels of vascular endothelial growth factor (VEGF) in psoriasis, but none of them evaluated it after reaching a PASI-75 response, as a practical treatment goal. The aim of this study was to evaluate serum levels of VEGF in moderate to severe psoriatic patients before and after treatment compared with healthy controls.Methods: This study was approved by the Ethics Committee of Shahid Beheshti University of Medical Sciences. Fifty-eight patients with moderate- severe psoriasis and 60 age-and gender-matched healthy controls were recruited to this study. Serum VEGF levels (pg/ml) of both groups were measured. We used Psoriasis Area and Severity Index (PASI) scoring to assess disease activity in patients. According to the disease severity, the patients received proper treatment. When they reached a PASI-75 response, serum VEGF levels were measured once more.Results: In our study, the median serum VEGF level was significantly higher in psoriatic patients (before and after treatment) as compared to healthy controls. Moreover, patients showed a significant reduction in their serum VEGF levels after reaching PASI-75. The median time of therapeutic effect (reaching a PASI- 75 response) was four months. Furthermore, our study showed a significant correlation between the serum VEGF level and age, BMI, PASI, and disease duration (P

We hereby report a 79-year-old Iranian man presenting with nail dystrophy and subsequent development of purpuric and ecchymotic plaques, hemorrhagic bullae, and infiltrated papules on the head, neck and trunk. Histological examination of the gingiva, bone marrow aspiration, and biopsy confirmed the diagnosis of primary systemic amyloidosis. In this case, nail dystrophy was the presenting sign of primary systemic amyloidosis, which is a recognized but rare manifestation of this disorder. According to this case report, we could suggest that nail dystrophy may provide a clue for early diagnosis of primary systemic amyloidosis, which would ultimately increase the survival of the patient.

Reactive perforating collagenosis is one of the perforatingdermatoses; the acquired form is characterized by transepithelialelimination of altered collagen bundles. It has been seen inassociation with multiple disorders including diabetes mellitus,renal failure, hyperparathyroidism, liver disease, neurodermatitis,IgA nephropathy, and periampullary carcinoma with jaundice.According to the literature, there is no report of reactiveperforating collagenosis in association with pulmonary papillaryadenocarcinoma, and our study is the first to report it.

Background: Psoriasis is a common and chronic inflammatory skin disease that has profound adverse effects on patients’ wellbeing. Trace elements are essential to biochemical processes in the body and are involved in immunological and inflammatory reactions such as keratinization and melanin formation. The aim of this study was to evaluate the essential metals in psoriasis in comparision with healthy controls. Method: We investigated serum levels of zinc, copper, and magnesium in 40 psoriatic patients and age and sex matched controls. Result: Psoriatic patients showed significantly higher serum levels of copper / zinc and lower magnesium in comparison with the control group. No significant differences were seen in copper and zinc levels. There was no correlation between serum levels of these elements and psoriasis severity except for zinc; the serum level of zinc was inversely correlated with psoriasis severity. Conclusion: This study demonstrated some disturbances in serum levels of metals in psoriasis. More studies are required to clarify the importance of these findings in etiopathogenesis or treatment.

A 20-year-old girl presented with a one-week history of fever and chills, malaise, generalized erythema (including the face, trunk, back and extremities), edema (initially the face and then lower limbs) and hoarseness (Figure 1). Physical examination revealed low-grade fever, jaundice, lymphadenopathy (posterior cervical, submandibular, <1 cm, no axillary, no inguinal). Dermatological examination showed diffuse erythema (erythroderma), edema (generalized, especially periorbital and lips), and mild jaundice (scleral and sublingual). No mucosal lesions or nail changes were seen. She had a history of epilepsy since 3 years ago and had been under treatment with sodium valproate until 1.5 month ago when she discontinued the medication. She had an epileptic attack then and therefore carbamazepine was started for her. Positive laboratory findings were anemia, leukocytosis with eosinophilia (20%), elevated liver enzymes, and direct hyperbilirubinemia. Other routine laboratory tests, electrocardiogram, chest x-ray, and viral markers (including HBV, HCV and EBV) were unremarkable. Abdominal sonography revealed thickening of gall bladder and fluid in posterior choledosac. A punch biopsy was taken from her forearm skin.

Introduction: Pemphigus vulgaris is an autoimmune blistering disease of the skin and mucous membrane. Antiphospholipid antibodies are a group of autoantibodies found in patients with autoimmune diseases. Due to the risk for thrombotic events in autoimmune diseases, we decided to evaluate the correlation between pemphigus vulgaris and predictive elements of atherothrombosis including antiphospholipid antibodies and homocysteine. Methods: IgG and IgM anticardiolipin antibodies, IgG anticardiolipinbeta 2 glycoprotein I, lupus anticoagulant and total homocysteine were evaluated in the serum of 39 new cases of pemphigus vulgaris and healthy matched controls. Results: The prevalence of antiphospholipid antibodies, lupus anticoagulant and total homocysteine in pemphigus vulgaris patients showed no significant difference with healthy controls. Conclusion: Pemphigus vulgaris seems not to be similar to some other organ specific autoimmune diseases in which there is an increase in atherothrombotic factors including antiphospholipid antibodies and homocysteine.

Background: Basal Cell Carcinoma (BCC) is the most common type of skin cancer in human beings. Photodynamic therapy (PDT) is a novel therapeutic method which may be regarded as a non-invasive useful alternative for traditional treatments of BCC. This study was designed with the aim of evaluating the primary response of BCC to PDT.Methods: This clinical trial was performed on 28 BCC lesions. Patients were treated with ALA-PDT monthly for 1-6 sessions and evaluated for clinical response, cosmetic results and probable side effects.Results: Twenty three out of 28 lesions showed response to PDT (9 showed complete response and 14 showed partial response). The cosmetic result was excellent or good in 77.5% of the cases. In 92.8% of the cases, no or mild side effects were observed. Patients with a positive history of radiotherapy responded less (p<0.05). No significant relationship was found between patients' age, sex, localization, diameter or type of BCC with clinical response.Conclusion: PDT might be a good therapeutic option in the treatment of BCC, especially the superficial type, with high efficacy and few side effects.
