Rheumatoid arthritis (RA) is a chronic inflammatory polyarithritic disease
associated with remission and exacerbation with different immunological
features.Rheumatoid factor(RF) screening test was used quantitatively and qualitatively
using an enzyme immunoassay (EIA), RF-isotypes (RF-IgG, RF-IgM, RF-IgA) ,
Interleukin-18 (IL-18) and Interleukin – 18 binding protein (IL-18BP) were detected
quantitatively usingenzyme linked immunosorbent assay(ELISA). Results indicated a
51% positivity in RF among RA patients and a prevalence of the RF-isotype (RF-IgM)
with the highest level at (41.6±16.3 U/ml) (p < 0.05) among other RF-isotypes at a
percentage of 85.5% , results also indicatedan elevated serum level of IL-18 and IL-
18BP(225±24.8 pg/ml), ( 5.2 ± 2.1 ng/ml ) respectively compared to healthy control
(HC)group (65±8.4 pg/ml )(p<0.01) , ( 2.9 ± 1.3 ng/ml ) (p<0.05) respectively, and
ratio of IL-18/IL-18BP serum levels in RA patients were significantly higher than in HC
group (p<0.05) which increased the importance of IL-18BP in therapeutic strategy. In
conclusion RF-IgM may be an important complimentary detection method for RA
among the other isotypes ,IL-18 with its IL-18BP may play an important role in RA
which need to be further investigated.
ackground An autoimmune and inflammatory illness called rheumatoid arthritis (RA) occurs when your immune system mistakenly attacks normal cells in your body. Interleukin-35 is a brand-new cytokine that belongs to the immunosuppressive and anti-inflammatory IL-12 family. β -herpesvirus that produces inflammation and stays dormant in its host for life is the human cytomegalovirus. Human herpesvirus (HCMV) has been at the core of several RA-related theories. Objective The current study looked at the association between RA and serum IL-35 levels as well as the association between RA and CMV. Patients and methods Blood samples were taken in the Baghdad Teaching Hospital and Typical Rheumatology Unit from January 2022 to Mars 2022 for the curre

The association between IL1B gene single nucleotide polymorphism (SNP: rs16944) and rheumatoid arthritis (RA) in a sample of Iraqi patients was investigated. Fifty-one RA patients (21 males and 30 females) were enrolled and their age range was 20 - 63 years (44.9 ± 1.5 years). In addition to patients, 45 apparently healthy control subjects were also enrolled in the study. They matched patients for ethnicity (Iraqis), gender (14 males and 31 females) and age (41.3 ± 1.3 years). Analysis of Hardy-Weinberg equilibrium (HWE) in RA patients and controls revealed that the IL1B ge

Many investigators studied the microbial infectious present in Iraqi patients with RA; however, to the best of our knowledge, there is no previous study detected the CMV DNA and antibodies to RA disease. Hence, the current study aimed to investigate the presence of CMV DNA and antibodies in Iraqi RA patients. A total of 58 blood samples were collected from patients with clinical signs of rheumatoid arthritis, along with 32 samples of apparently healthy individuals as a control group. These samples were tested for rheumatoid factor (RF), CMV IgM antibodies and viral DNA during the acute and

Sixty patients with RA and matched number of apparently healthy volunteers were included in the study. Spectrophotometric methods were used to determine Peroxy nitrite (ONOO), Nitric oxide (NO), Nitric oxide synthase activity (NOS) cycloxygenase-2 activity (COX-2), glutathione peroxidase (GPX) activity and superoxide dismutase (SOD) activity in serum of both groups. Colorimetric assay kits were used to determine Iron. Rheumatoid factor (RF) was determined using Imuno-Latex kit. ONOO, NO levels, and NOS activity were significantly higher in the patients compared to the control group. Conversely, Iron level, SOD

Aim of this study was carried out to estimate changes of the (interleukin-one beta, tumor necrosis factor – alpha and C-reactive protein) levels in unstimulated whole saliva during the leveling stage of orthodontic tooth movement. Materials and methods: The sample consisted of thirty adult patients (12 males and 18 females) with ages ranges (19-23) years. Each sample had Class I and Class II malocclusion dental classification and required bilateral extraction of their maxillary first premolars, und

Peptidyl arginine deiminase type IV (PADI4) is an enzyme responsible for the posttranslational conversion of arginine residues into citrulline. Real-time polymerase chain reaction (RT-PCR) is a specific technique was used to determine gene polymorphism. One hundred twenty three patients molecularly confirmed with RA and sixty healthy control subjects were recruited. By applying the logistic regression analysis, some alleles and genotypes were associated with susceptibility to RA. Under the allelic model, C allele frequency was significantly increased in RA patients compared
