Abstract
BACKGROUND The classic treatment for pemphigus vulgaris is prednisolone. Immunosuppressive drugs can be used in association. OBJECTIVE To compare the efficacy of Azathioprine in reducing the Disease Activity Index (DAI). PATIENTS AND METHODS A double blind randomized controlled study was conducted on 56 new patients, assigned to two therapeutic groups: (i) prednisolone plus placebo; (ii) prednisolone plus Azathioprine. Patients were checked regularly for 1 year. 'Complete remission' was defined as healing of all lesions after 12 months, and prednisolone <7.5 mg daily, (DAI ≤ 1). Analysis was done by 'Intention To Treat' (ITT) and 'Treatment Completed Analysis' (TCA). RESULTS Both groups were similar in age, gender, disease duration, and DAI. Primary endpoint: By ITT and TCA, the mean DAI improved in both groups with no significant difference between them. The difference became significant for the last trimester (3 months; ITT: P = 0.033, TCA: P = 0.045). Secondary endpoint: The total steroid dose decreased significantly in both groups, with no significant difference between them, except for the last trimester (ITT: P = 0.011, TCA: P = 0.035). The mean daily steroid dose decreased gradually in both groups becoming statistically significant in favour of azathioprine, in the last trimester, especially at 12th months (ITT: P = 0.002, TCA: P = 0.005). Complete remission was significant at 12 months only for TCA (AZA/Control: 53.6%/39.9%, P = 0.043). LIMITATIONS Sample size was rather small to demonstrate all differences. Other limitations include the choice of primary and secondary endpoints and the unavailability to measure thiopurine methyltransferase activity. CONCLUSION Azathioprine helps to reduce prednisolone dose in long-run.

Abstract
BACKGROUND The aim of the article is demonstrating an application of multiple imputation (MI) for handling missing clinical data in the setting of rheumatologic surveys using data derived from 10291 people participating in the first phase of the Community Oriented Program for Control of Rheumatic Disorders (COPCORD) in Iran. METHODS Five data subsets were produced from the original data set. Certain demographics were selected as complete variables. In each subset, we created a univariate pattern of missingness for knee osteoarthritis status as the outcome variable (disease) using different mechanisms and percentages. The crude disease proportion and its standard error were estimated separately for each complete data set to be used as true (baseline) values for percent bias calculation. The parameters of interest were also estimated for each incomplete data subset using two approaches to deal with missing data including complete case analysis (CCA) and MI with various imputation numbers. The two approaches were compared using appropriate analysis of variance. RESULTS With CCA, percent bias associated with missing data was 8.67 (95% CI: 7.81-9.53) for the proportion and 13.67 (95% CI: 12.60-14.74) for the standard error. However, they were 6.42 (95% CI: 5.56-7.29) and 10.04 (95% CI: 8.97-11.11), respectively using the MI method (M=15). Percent bias in estimating disease proportion and its standard error was significantly lower in missing data analysis using MI compared with CCA (P< 0.05). CONCLUSION To estimate the prevalence of rheumatic disorders such as knee osteoarthritis, applying MI using available demographics is superior to CCA.

Abstract
AIM To study the effect of acetazolamide on cystoid macular oedema (CMO) in patients with Behcet's disease. PATIENTS AND METHODS A total of 67 eyes of 35 Behcet's patients with chronic, but well-controlled uveitis, and CMO were randomised into a double-masked, crossover trial comparing the effect of acetazolamide vs placebo. The patients received an initial 4-week course of either 250 mg acetazolamide twice daily (b.i.d.) or placebo, followed by a 4-week washout period. They then received a 4-week course of the reverse study medication. An improvement in visual acuity and fundus fluorescein angiographic findings was assessed. RESULTS In total, 29 patients (55 eyes) completed the trial and were available for analysis. Of the 29, 16 men and 13 were women. The age range was 13-50 years (mean 33.6 years). Patients on acetazolamide showed a slightly better improvement of angiographic signs (at least by one grade improvement) over that of placebo (12 vs five eyes). They also had less deterioration of angiographic signs over that of placebo (three vs seven eyes). However, these findings were not statistically significant (P=0.99). Acetazolamide had no statistically significant effect (P=0.53) on the improvement of visual acuity of patients over that of placebo (13 vs eight eyes), nor on the deterioration of visual acuity (three vs 11 eyes). CONCLUSION Despite seemingly favourable results, the 4-week course of acetazolamide (250 mg b.i.d.) has no statistically significant effect on the improvement of the visual acuity and the fluorescein angiographic findings in Behcet's patients with CMO.

Abstract
We have previously suggested that in a Japanese population the susceptible locus for Behçet's disease (BD) is HLA-B51 itself. To confirm this finding in another population, we performed HLA class I typing using the PCR-SSP method and analyzed eight polymorphic markers distributed within 1100 kb around the HLA-B gene using automated sequencer and subsequent automated fragment detection by fluorescent-based technology with the DNA samples of 84 Iranian patients with BD and 87 healthy ethnically matched controls. As a result, three microsatellite alleles (MICA-A6, MIB-348, C1-4-1-217) and HLA-B51 were found to be strongly associated with BD. Of these alleles HLA-B51 is the most strongly associated allele. There were no alleles that were increased in allele frequency at any microsatellite loci centromeric of MICA or telomeric of HLA-B51. Therefore, HLA-B51 was confirmed to be by far the most strongly associated gene with BD in an Iranian population.

Abstract
It is well known that Behçet's disease (BD) is strongly associated with human leukocyte antigen (HLA) B51 in many ethnic groups. However, there has been no published report as yet with respect to this association among the Iranian people. Furthermore, since it is now known that the B51 antigen can be encoded by 21 alleles, B*5101-B*5121, we performed HLA-B*51 allele typing as well as HLA class I genotyping of 48 Iranian patients with this disease. As a result, the frequency of the B*51 allele was significantly higher (62.1%) in the patient group as compared with the ethnically matched control group (31.8%) (Pc=0.067, R.R.=3.51). In the genotyping of B*51 alleles, 33 out of the 36 B*51-positive patients possessed B*5101 and the remaining 3 carried B*5108. This study revealed that Iranian patients with BD also had a strong association with HLA-B51. In addition, this significantly high incidence of HLA-B*51 was found to be caused by an increase in both the HLA-B*5101 and HLA-B*5108 alleles. However, there was no significant difference in the HLA-B*51 allelic distribution between the patient and control groups.

Abstract
We recently identified a trinucleotide repeat polymorphism, (GCT)n, within the transmembrane (TM) segment of the human MHC class I MICA gene (MHC class I chain-related gene A). Five distinct alleles (A4, A5, A5.1, A6, A9) corresponding to 4, 5, 5 with one nucleotide insertion, 6 and 9 repetitions, respectively, have been detected in various HLA-homozygous B cell lines. Here we present allele frequencies for this trimeric short tandem repeat (STR) in 604 unrelated individuals collected from nine human populations (Japanese, Northern Han, Hui, Uygur, Kazakhstan, Iranian, Saudi Arabian, Greek and Italian) determined using the polymerase chain reaction (PCR) combined with fluorescent-based automated fragment detection technology. All alleles were present in each population, but allelic distributions varied from one population to another. No new alleles (such as A7 or A8) were identified. The evolutionary and structural significance of these data as well as the potential application to forensic medicine is discussed.

Abstract
Patients with systemic lupus erythematosus (SLE) are susceptible to infections, notably salmonellosis. We report 37 cases of salmonella infection in 24 patients with SLE. These cases were detected in a group of 770 patients with SLE. All the patients were women, with a mean age of 25.6 years. At the onset of salmonella infection, 81% were taking prednisolone and 27% were taking cytotoxic drugs. Renal involvement was present in 75% of patients, which was approximately the same as in other SLE patients. Bacteremia, arthritis, osteomyelitis and rare manifestations of salmonellosis, including pulmonary and urinary tract involvement, were encountered. Diagnosis was based on isolation of the microorganism, mostly from blood cultures. Salmonella species other than typhi and paratyphi were often responsible. Widal agglutination test was positive in less than half the cases, and leukopenia was not seen frequently. Recurrence of infection in 29% of the patients and the high mortality rate (28.5%), despite the conventional period of appropriate antimicrobial treatment, show a poor prognosis of salmonellosis in SLE patients. This special picture of salmonellosis argues for a much longer period of treatment in these patients.

Abstract
Skeletal lesions are not uncommon in von Recklinghausen neurofibromatosis. Most of them are considered to be dysplastic in nature. Association of osteomalacia or rickets with neurofibromatosis has been documented only rarely. Reported herein is a 40-year-old woman with known von Recklinghausen neurofibromatosis who presented with bone pain, multiple pseudofractures, marked increase in osteoid by bone biopsy, and hypophosphatemia with renal phosphate wasting. Treatment with oral phosphate and vitamin D was effective. A survey of the literature revealed that 34 similar cases have been reported in the past. Although the exact pathogenetic mechanism remains to be determined, osteomalacia in neurofibromatosis appears to be distinct from more common dysplastic skeletal affections of this disease, being characterized by later onset in adulthood as a rule, renal phosphate loss with hypophosphatemia, multiple pseudofractures in typical cases, and response to treatment with pharmacological dose of vitamin D with or without phosphate supplement.
