 Systemic lupus erythematosus is an autoimmune disease in which organs and cells are damaged in the initial stages by tissue-binding autoantibodies and immune complexes. Clinical, demographic and laboratory information of patients with SLE in Ardabil province is the aim of this study.

 The present study is a cross-sectional descriptive study that examines demographic data (age, gender), clinical information such as the first manifestation of the disease, clinical symptoms, etc., and laboratory findings such as CBC, ESR, CRP, proteinuria, FANA, Anti dsDNA, C3, C4, Anti RO and APS Ab of patients who referred to the rheumatology clinic of Imam Khomeini Hospital (RA) in 2021.

 Information related to the clinical characteristics of 50 patients, including 46 women (92%) and 4 men (8%), with an average age of 12.14 ± 40.78 years (range: 21-73) and age at diagnosis of 10.62 ± 31.76 years were investigated. The most common initial complaint in the studied patients was related to isolated joint symptoms (28%). The most common clinical symptoms observed in the examined patients were related to joint symptoms along with sensitivity to light with a frequency of 20%. ANA, anti-dsDNA tests positivity and reduced C3 and C4 levels were observed in 88%, 70% and 26% of patients, respectively.

 The establishment of a registry system for the structured registration of information of patients with systemic lupus erythematosus in each region is necessary to a better understanding of the characteristics of the disease and better management policy of patients.

Knee osteoarthritis is an important cause of pain and disability in the community. The present study investigated the risk factors for primary osteoarthritis of the knee in patients with knee pain and their relationship with knee osteoarthritis.

87 patients were included in the study and were matched in terms of age. Cases consisted of female patients less than 50 years of age with knee pain and the control group was selected from patients under 50 years of age with knee pain and no radiographic findings of osteoarthritis.

This study showed that the rate of osteoarthritis of the knee was significantly related to body mass index (p=0.001). The relationship between knee osteoarthritis and ESR was not significant, but an increase in CRP with a p-value of 0.01 was associated with a risk of approximately a 3.5-fold increase in knee osteoarthritis. With increasing education, the rate of knee osteoarthritis decreased (p=0.022). The Increased circadian outpatient activity was significantly associated with increased knee osteoarthritis (p=0.032). In performed assessments on osteoarthritis of the knee, there was no statistically significant relationship between the type of bathroom used, the use of stairs, and residential houses.

Knee osteoarthritis has a relationship with body mass index, Education level, CRP index, and circadian activity level. it is recommended to lose weight in people with abnormal body mass index, exercise, and improve their lifestyle to reduce the incidence of knee osteoarthritis and disability.
