Prevalence and Severity of Depression and Anxiety in Patients With Systemic Sclerosis: An Epidemiologic Survey and Investigation of Clinical Correlates.

BACKGROUND: Systemic sclerosis (SSc) is a chronic multisystem connective tissue disorder with detrimental impact on quality of life. Patients with SSc face emotional distress and frequently meet criteria for a psychiatric disorder. However, the pattern of psychiatric manifestations may vary according to socioethnic background. OBJECTIVES: We investigated the prevalence of depressive and anxiety symptoms and examined their association with sociodemographic and clinical factors in Iranian SSc patients. METHODS: Depressive and anxiety symptoms were evaluated by Beck Depression Inventory and Cattell questionnaire in 114 SSc patients. The associations between sociodemographic and clinical factors and depressive/anxiety symptoms were examined via multivariate analysis. RESULTS: The prevalence of depressive symptoms was 68.4%. There was a significant association between depressive symptoms and pulmonary and gastrointestinal manifestations. Also, diffuse SSc patients were more prone to depressive symptoms. Mean Rodnan scores were significantly higher in patients with depressive symptoms in comparison with subjects with no depressive symptoms. The prevalence of anxiety symptoms was 23.6%. Anxiety symptoms were not associated with demographic characteristics, SSc subtype, disease duration, Rodnan score, other clinical features, and previous history of depression in the patients or their family. The coincidence of anxiety and depression was 82.8%. CONCLUSIONS: Depressive and anxiety symptoms are prevalent among Iranian SSc population. The depressive symptoms showed correlation with pulmonary and gastrointestinal involvement, as well as diffuse SSc subtype.

The effect of Ramadan fasting on quiescent systemic lupus erythematosus (SLE) patients' disease activity, health quality of life and lipid profile: a pilot study.

SLE is a common autoimmune disease with considerable morbidity. Ramadan fasting is a religious custom Muslims regularly practice. We aimed to evaluate the effect of Ramadan fasting on SLE patients' disease activity, health quality of life and lipid profile. We conducted this case control study as a pilot study in 40 quiescent SLE patients, 21 cases who decided to fast and 19 controls who decided not to have Ramadan fasting between August and November 2009 in lupus unit of Rheumatology Research Center in Tehran University of Medical Sciences, Iran. They were assessed for SLE Disease Activity Index, lipid profile and quality of life with Short-Form 36 (SF-36) Health Survey, 1 day before Ramadan, the day after and 3 months after Ramadan fasting. After 24.1 ± 5.4 (mean ± SD) days of fasting, anti-ds DNA increased for 0.34 ± 0.41 mmol/dL in cases versus 0.07 ± 0.31 in controls (P = 0.026). Likewise C3 increased more dramatically in cases (16.8 ± 17.5 vs. 2.3 ± 13.2 mg/dL, P = 0.006). Three months after fasting, anti-ds DNA was still increased 0.28 ± 0.46 mmol/dL in cases while a 0.02 ± 0.43 mmol/dL drop in controls was detected (P = 0.04). On the contrary, C3 returned to baseline. These changes were not accompanied with significant changes in disease activity and health quality of life. Ramadan fasting had no effect on lipid profile except for delayed total cholesterol decrease in cases in comparison with controls (16.4 ± 29.4 decrease vs. 4.6 ± 23.9 mg/dL decrease, P = 0.018). Ramadan fasting probably has no detrimental effect on SLE patients' disease activity and their quality of life in the quiescent phase of disease.

Clinical and immunological pattern of systemic lupus erythematosus in men in a cohort of 2355 patients.

AIM: To investigate the impact of gender on expression of systemic lupus erythematosus (SLE) in a cohort of 2355 SLE patients as one of the largest series of cases among the present reports. METHOD: In this retrospective study we used medical records of all patients (239 male and 2116 female) of the SLE registry of Rheumatology Research Center (RRC), Tehran University of Medical science (TUMS), Iran. Both clinical and paraclinical manifestations of SLE patients have been registered in this database since 1976 and updated during their follow-up. Chi-square test was used to compare the clinical and paraclinical manifestations in men and women at disease onset and during the disease course. We used logistic regression to compute odds ratios with 95% confidence intervals. A P-value < 0.05 was considered as statistically significant. RESULTS: Mean age at disease onset was 25 ± 11.8 and 24.5 ± 10.3 years in men and women, respectively (P = 0.48). Comparison of clinical and immunological manifestations showed that male patients had a higher prevalence of mucocutaneous (43.5% vs. 33.7%, P = 0.005) and a lower prevalence of musculoskeletal symptoms (44% vs. 54.7%, P = 0.003) as the initial manifestation. During the disease course, discoid rash (25.9% vs. 13%, P = 0.000) and type IV lupus nephritis (23.4% vs. 18.1%, P = 0.03) were significantly more common, whereas arthritis (61.1% vs. 71.7%, P = 0.01) and leukopenia (28.5% vs. 35.8%, P = 0.024) were significantly less common in men. CONCLUSION: This study reveals gender influence on some manifestations of SLE. Considering sex differences is recommended in diagnostic and therapeutic features of the disease.

Systemic lupus erythematosus in Iran: a study of 2280 patients over 33 years.

OBJECTIVE: Systemic lupus erythematosus (SLE) as a chronic autoimmune disease has a worldwide distribution. There is a wide variation in the natural history of SLE among different ethnic and geographic groups. The aim of this study was to show the manifestations of SLE in Iranian patients. METHODS: The study was on manifestations of SLE according to the database of the Rheumatology Research Center (RRC), Tehran, Iran, on registered patients during the period of 1976 to 2009. RESULTS: A total of 2280 SLE patients (2052 female and 228 male) were studied. The female : male ratio was 9 : 1 and the mean age at presentation was 24.4 ± 10.4 years. Prevalence of manifestations included: musculoskeletal (83.2%), cutaneous (81.1%), renal (65.4%), neuropsychiatric (23.4%), pulmonary (21.5%), cardiac (17.2%), and hematologic (66.4%) symptoms. There was positive antinuclear antibodies in 86.4% and anti-DNA in 82.3% of patients. Overlap syndrome and positive family history with other autoimmune diseases were detected in 7.6% and 3.4% of patients, respectively. CONCLUSION: In our patients the prevalence of cutaneous involvement was similar to those of nearby countries (with similar climate). Renal involvement was seen more than some other countries especially more than European countries, while other manifestations (such as hematologic and joint involvement) were similar to European countries (with similar ethnicity). We may conclude that genetic and/or climatic factors may lead to different presentations of lupus.
