Chitinase-3-like 1 protein (YKL-40) is a glycoprotein primarily produced in the arthritic joint and plays a crucial role in inflammatory processes. The aim of the study is to establish the role of YKL-40 as a biomarker for rheumatoid arthritis (RA) compared to proinflammatory biomarkers and disease activity. The study included 58 patients and 18 control. Diseases activity score (DAS-28) and clinical disease activity index (CDAI) were measured. Serum level of YKL-40, tumor necrosis factor-α (TNF-α), interleukin-1B (IL-1β), erythrocyte sedimentation (ESR), rheumatoid factor (RF), C-reactive protein (CRP), and anti-citrullinated protein antibody (ACPA) were assessed. The results showed that the median serum YKL-40 level which was 5.42 ng/ml, the TNF-a level which was 123.6 ng/ml, and the IL-1B level which was 204.365 pg/dl were significantly higher in patients compared to control 3.28 (1.58–4.99) ng/ml, 56.47 (9.38–77.01) ng/ml and 67.887 (15.493–122.689)pg/dl respectively. There was no correlation between serum YKL-40 and disease activity, while there were significant associations observed with TNF-α (r=0.5,p =0.0001) and IL-1β (r=0.41, p=0.001). YKL-40 indicating good levels of RA prediction at 2.47 ng/ml, sensitivity 87.9%, specificity 58.6%, accuracy 78.1%, PPV 80.9%, and NPV 70.8%. In conclusion, a higher level of serum YKL-40 is found in RA patients. The findings from our study suggest a strong association between YKL-40 and the proinflammatory biomarkers. As a result, these biomarkers together might play a role in RA pathogenesis, and YKL-40 may be used as a potential diagnostic biomarker for RA.
Background: disturbed physiological rhythm of blood pressure in preeclampsia is a common finding. The role of oxidative stress in pathogenesis of preeclampsia is well accepted. Melatonin is a powerful free radical scavenger so it's rapidly consumed by enhanced reactive oxygen species in preeclampsia causing non-dipping in blood pressure.
Objective: To evaluate the change in plasma melatonin levels in patients with preeclampsia and its relationship with blood pressure.
Patients and methods: In this prospective case control study a total of 40 primigravidae pregnant women were recruited during the period of 11 months between August 2015 and August 2016 in Baghdad teaching hospital, medical city, Iraq, divided into two groups:

Background: Patients with rheumatoid arthritis show predominance of metabolic disorder characterized by overweight, central obesity, dyslipidemia, and impaired glucose tolerance, specifically, few studies have explained insulin resistance in this disease.
Objective: The aim of the present study is to examine insulin resistance and the risk of developing diabetes mellitus in middle age Iraqi women with early rheumatoid arthritis.
Patients and methods: This work involved seventy female with early rheumatoid arthritis. Who was attending to the National Diabetic Center (NDC) of Al-Mustansiriya University and 35 healthy subjects as a control group. From all subjects blood sample was drawn in fasting state to measure the biochemical para
Background: Rheumatoid arthritis (RA) is an inflammatory disease of unknown etiology characterized by joint inflammation and the presence of autoantibodies, mostly Anti-cyclic citrullinated peptide antibody (ACCP) which are released when the body loses its ability to distinguish between self and foreign molecules. Serum amyloid A2 (SAA2) is an acute phase protein produced in response to inflammatory conditions including RA.
Objectives: To investigate the prognostic ability of SAA2 in comparison with ACCP and the prediction of disease activity and response to treatment by Methotrexate and Etanercept in Iraqi RA patients.
Patients and methods: A case control study, on a to
... Show MoreRheumatoid arthritis is an inflammatory chronic disease with an autoimmune pathogenesis. To determine the role of Helicobacter pylori as a trigger agent, twenty five patients with rheumatoid arthritis of ages (15-47) years have been investigated and compared with twenty healthy individuals. All the studied groups were carried out to measure the rheumatoid arthritis (RA) IgM, anti-CCP antibody IgG and IgA by ELISA test and by measured anti-IgG antibody level of H. pylori by using ELISA and IFAT techniques. The present study showed significant differences (P< 0.05) of anti-H. Pylori in sera of RA patients than control group, this lead to suggest that H. pylori had a role in pathogenesis of RA.
Background: Anti-RA33 antibodies and anti-CCP antibodies are highly specific markers for rheumatoid arthritis (RA), but are not detectable in all RA patients.
Anti-RA33 antibodies are directed to the heterogeneous nuclear ribonucleoprotein A2 (hnRNP-A2),while anti-CCP antibodies are directed to modified epitope on proteins that undergo conversion of amino acid arginine to citrullin by citrullination.
Objectives: The aim of this study was to show the correlation between anti-RA33 antibodies, anti-CCP antibodies and rheumatoid factor (RF) in terms of sensitivity and specificity for the diagnosis of rheumatoid arthritis in Iraqi patients.
Subjects and methods: This s

Background In rheumatoid arthritis, your immune system attacks the tissue lining the joints on both sides of your body. Other parts of the body may also be affected. Unsure of the exact cause. Two separate genes termed IL12A (p35) and IL12 encode the heterodimeric cytokine known as IL12 (p40). Several different hematopoietic cell types can have several different hematopoietic cell types that can generate antigen-presenting cells (APCs), including DCs and macrophages. Objectives This study aimed to investigate if the interleukin IL-12B gene's common polymorphisms in an Iraqi population were associated with RA. Material and methods Blood samples were taken from 70 Iraqi patients with RA illnesses and 30 Iraqi controls during the periods from

... Show MoreBackground: Rheumatoid arthritis (RA) is a chronic and debilitating autoimmune disease characterized by chronic inflammation with subsequent cartilage and bone destruction. Cytokines are key mediators of inflammation and can be found in abundance both in the joint and blood of patients. This study was designed to evaluate the role of pro- and anti-inflammatory cytokines in pathogenesis of RA, as well as study the correlation among these cytokines.
Patients and methods: Forty patients with RA and thirty age-matched healthy controls were included in this study. Serum cytokines were measured by enzyme-linked immunosorbent assay.
Results: The serum levels of pro-inflammatory cytokines (IL-1α, IL-2, IL-6, IL-8
