Background: Rheumatoid arthritis (RA) is an autoimmune disease, where the normal joint tissues attacked by body’s immune system, causing their inflammation. Cluster of Differentiation 69 (CD69) is a human transmembrane C-Type lectin protein encoded by the CD69 gene. It’s expression was induced by activation (in vivo and in vitro) of T lymphocytes and Natural Killer (NK) Cells. As CD69 early activation has been implicated in the pathogenesis of some inflammatory diseases, its expression on peripheral blood T-lymphocytes must be evaluated.
Objective: To evaluate the expression of CD69 on peripheral blood T-lymphocytes in RA Iraqi patients.
Patients and methods: This study carried out between March 2014 and May 2014. The study involved 40 patients diagnosed with RA attending rheumatology outpatient’s clinic at Baghdad medical city teaching hospital diagnosed clinically and classified according to the 2010 American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) classification criteria for rheumatoid arthritis, compared to 40 apparently healthy individuals as a control group. Erythrocyte sedimentation rate (ESR) was measured by Westergren method. Flow cytometric immunophenotype analysis applied on T-lymphocytes for measuring the fluorescence intensity of CD3 and CD69 expression on those cells.
Results: This study showed that the mean of ESR in RA patients was (66.8) while in healthy control it is only (20.4). And the mean of CD3 was higher in healthy individuals (41.88) than in RA patients (35.32), while the mean of CD69 was significantly higher among RA patients (11.09) than that of healthy controls (3.58). Also a moderately strong positive linear correlation was found between CD69 expression and RA severity.
Conclusions: the expression of CD69 was up-regulated in freshly isolated peripheral blood lymphocytes from RA patients in comparison to healthy individuals.
Back ground:-Rheumatoid arthritis is one of the most common forms of inflammatory polyarthritis, with a prevalence of approximately 0.8% of adults worldwide, Rheumatoid arthritis patients may become disabled within few years if untreated that may lead to permanent disability. Different biomarkers have been assessed for the improved diagnosis of Rheumatoid arthritis, including a wide range of autoantibodies. However, only rheumatoid factor (RF) and anti-cyclic citrullinated peptide (ACCP) have gained wide acceptance.
Aim of the study to investigate the levels of ACCP, Leptin, and Lipoprotein (a) in females with RA to provide information on possible pathophysiologic mechanisms, and to give re
... Show MoreRheumatoid arthritis (RA) is a systematic autoimmune disorder with chronic inflammation changes of unknown etiology. Various synovial inflammatory and proliferative alterations may contribute to the cartilaginous tissues and invasive bony tissues, leading to destructive joints and malformed bones. This disease is mostly due to infective microorganisms or genetic susceptibility causing immune system disturbances through triggering both T-cells and B-cells. Furthermore, different immune cells may secret cytokines, which are responsible for some RA pathogenesis activity. From ninety individuals, serum sample was collected; thirty of them were normal and sixty cases were patients with RA attended a privet medical clin

Patients and Methods: 82 patients with RA and 40 control subjects were included in this prospective study. They were submitted to medical history, physical measurements (height, weight and BMI) and spirometric evaluation for FVC, FEV1, FEV1%, PEFR and FMF (FEF25-75%).Objective: The aim of the study is to detect pulmonary involvement, classify the type of involvement (whether obstructive, restrictive or mixed), and to find out whether pulmonary system was involved in the early stage of the disease and is asymptomatic and to determine the as

Background: Cytokines have an essential contribution to the inflammatory response and the development of chronic inflammation. Therefore, it has a pivotal role in the pathogenesis of rheumatoid arthritis (RA). Interleukins are closely related to RA, and the exact role of some interleukins in the pathogenesis of RA is not yet known.
Objectives: To evaluate the levels of interleukins and their ratio, since the levels of interleukins 35 and 39 in RA patients have not yet been determined in Iraq.
Patients and methods: An ELISA (enzyme-linked immunosorbent assay) was used to measure the levels of interleukins in the blood of 56 patients with RA and 44 healthy volunteers who were enrolled in the study from November 2021 to March 2022.
Rheumatoid arthritis (RA), is an autoimmune, and inflammatory disease that is closely related to the destruction of cartilage and bone. DC-SIGN are important types of C-type lectin receptors (CLRs), expressed on dendritic cells and macrophages, and have a central role in regulating innate and adaptive immunity, function as pattern recognition receptors, and as cell adhesion molecules. Recent evidence has demonstrated that DC-SIGN is involved in the pathophysiological of chronic inflammation, so DC-SIGN has been linked to several autoimmune and may play an essential indicator in the pathogenesis and progression of RA. Therefore, the purpose of this study is to determine the serum level of DC-SIGN in RA patients, as well as the level of DC
... Show MoreBackground: Periodontitis is a chronic inflammatory disease which is initiated by an infection of the oral microorganisms and it involves the humoral and cellular characteristics of the host response. The periodontal disease is found to develop due to a series of interactions among the periodontotrophic herpes viruses, the periodontopathic bacteria and the host immune reactions.Recent studies have demonstrated that various human viruses, especially human cytomegalovirus seems to play a part in the pathogenesis of periodontitis. Periodontitis is an infectious disease involving specific bacteria and viruses.
Objectives: The present study was initiated to evaluate the percentage of human cytomegalovirus in periodontitis patients and dete
Background: Fibromyalgia syndrome and psoriasis share various soft problems. In addition, patients with psoriasis can experience subjective joint swelling and pain (Fibromyalgia syndrome) and objective swelling (Psoriatic arthritis) with the latter requiring systemic disease modifying antirheumatic drugs while the former requires anti-fibromyalgia measures.
Objective: To assess the rate of fibromyalgia syndrome in a sample of Iraqi patients with psoriasis.
Patients and Method: A sample of one hundred and twenty Iraqi patients with psoriasis and another one hundred and twenty healthy individuals matched for age and sex, serving as control group were studied. Full history was taken and complete clinical examination was done and vario
Background: Rheumatoid arthritis (RA) characterized by local and systemic effects of inflammation has a wide range of biochemical markers implicated directly or indirectly to its pathogenesis.
Patients and method: Serum of (55 Females) of newly diagnosed RA and 23 healthy Females were used to estimate their interlukine levels.Objective: To evaluate interlukine 35 (IL-35) in Iraqi females with newly diagnosed
RA and to assess its contribution in the disease process.
Results: Females of RA showed a significant increase in the levels of interleukine 35(IL-35) and in the levels of High Sensitivity C-Reactive Protein (hs CRP). While there

In Iraq , Gastric cancer is the 9th commonest of the top cancers while colorectal cancers it is considered as the 7th commonest ten cancers.IL-10 appears to be more of a pro-tumor than anti-tumor properties in both colorectal and gastric cancers.
Objective:is to estimate the serum level of IL-10 in the Iraqi colorectal and gastric cancer Patientsand its relation to the progress of disease.
