Abstract
Background and Aim: Pemphigus vulgaris (PV) is an autoimmune blistering disease which is specific for skin and mucosal membranes. Its association with connective tissue diseases has already been reported. Considering this association, presence of Anti Nuclear Antibodies (ANAs) in PV patients will not be surprising. The aim of this study was to compare the frequency of ANA positive cases in patients suffering PV with a control group.
Methods: In this case-control study, the cases were selected from the patients with PV whom were hospitalized at Razi Hospital, Tehran. The controls were chosen from patients who did not have PV. The data were collected using a questionnaire, which was designed for gathering information on participants' age, sex, PV phenotypes, and the result of ANA test. ANA positivity was assessed using indirect immunofluorescence, HEP2.
Results: In 8 (26.7%) of 30 PV patients and 3 (10.0%) of 30 controls ANA was positive (P=0.095). The most common ANA positive patterns among cases and controls were homogeneous and speckled patterns, respectively (P=0.26).
Conclusion: Although in this study the frequency of positive ANA result among controls was similar to what were reported in previous studies, the frequency of this finding among PV patients was different from the previous reports. Differences in the sensitivity of the laboratory kits used in different studies as well as in the threshold for ANA positivity, and differences in the patients' eligibility criteria in different studies may explain the observed discrepancies. Clinical follow up of the PV and requesting an ANA test in the case of appearance of the signs of connective tissue diseases is recommended.

Abstract
Background and Aim: Pemphigus is one of the most common types of autoimmune blistering disease that requires systemic immunosuppressive therapy. Immunosuppressive therapy has improved the disease outcome in recent decades, but long-term use of them has side effects. Recently, it has been tried to evaluate immunosuppressive drugs with less side effects. One of them is mycophenolate mofetil. The aim of this study was to evaluate of therapeutic efficacy of this drug in the patients with refractory pemphigus vulgaris.
Methods: Three hundred files of patients with pemphigus vulgaris were reviewed and among them 28 patients who had received mycophenolate mofetil due to resistance to treatment were entered to this study. The data were obtained from patients’ files and were analyzed using Kendall's tau-c correlation, Mann-Whitney and ANOVA tests.
Results: Male to female ratio was 1.8:1 with an average age of 43.3±13.6 year. Twenty-eight cases of pemphigus vulgaris were treated receiving 2gr/day mycophenolate mofetil + 1mg/kg/day prednisolone. Remission occurred after 3 months. Seventeen patients (10 men and 7 women) had complete remission. There was no significant association between gender and treatment response (P=0.58). There was no significant association between mean age of treated patients and untreated patients with treatment response (P=0.77). Also, there was no significant association between severity of mucosal (P=0.80) and severity of skin involvement with treatment response (P=0.80). Ten patients who received mycophenolate mofetil more than 12 months had treatment response to mycophenolate mofetil and they did not have any relapse in the follow up period.
Conclusion: Mycophenolate mofetil is effective and safe as an adjuvant therapy in patients with pemphigus vulgaris especially in refractory pemphigus. Initiation of the therapeutic effect is slow.

Abstract
Background and Aim: Pemphigus vulgaris (PV) is the most common bullous autoimmune disease, which can cause mortality and morbidity in the patients who suffer from it. Researches to find reliable noninvasive laboratory tests to diagnose and monitor PV patients are being conducted.The aim of this study is to find the sensitivity of serum and salivary anti-DSG1 and anti-DSG3 antibodies in the diagnosis of PV by ELISA and to compare the results of serum and salivary autoantibodies with each other.
Methods: In this case-control study, 40 newly diagnosed patients with PV were recruited. Forty healthy controls were also recruited to this study. The clinical diagnosis of PV was confirmed by histopathology and direct immunofluorescence (DIF). Demographic data, disease severity and phenotypes were recorded on the questionnaires, which were developed for this study. DSG1 and DSG3 ELISA test were performed on serum and salivary samples of patients and controls.
Results: The mean±standard deviation age of patients, 43.37±11.94, with a range of 26 to 71 years. The sensitivities of serum anti-DSG3 and anti-DSG1 were 85% (34 cases had positive test results) and 90%, (36 cases had positive test results) respectively. The sensitivities of salivary anti-DSG3 and anti-DSG1 antibodies were accordingly 42.5% (17 cases had positive test results) and 60%, (24 cases had positive test results) respectively.
Conclusion: While the sensitivities of serum ELISA in detection of anti-DSG1 and anti-DSG3 were significantly higher than those of salivary ELISA, since the levels of the latter are chnaging in parallel to those of serum ELISA, they might be used to monitor the disease activity.
