Objectives To examine the serum levels of interleukin (IL)-30 in patients with psoriasis and evaluate the correlations with the Psoriasis Area and Severity Index (PASI). Methods Serum was collected from 26 patients with psoriasis and 26 healthy controls in a case–control setting, and the level of IL-30 was determined using an enzyme-linked immunosorbent assay. Statistical analysis of the IL-30 levels among groups and further correlation analyses of IL-30 levels with PASI scores were performed. Results A significant increase in the level of IL-30 in patients with psoriasis compared with healthy controls was observed. In addition, a positive correlation between the IL-30 concentration and PASI scores was found in patients with psoriasis. Conclusion IL-30 is presumably involved in the proliferation of epidermal cells during the development of psoriasis. Further studies with a larger number of participants are required to comprehensively elucidate the biological roles of IL-30 in the pathogenesis of psoriasis.
Background & objectives: Introducing a nucleic acid test program is aimed to diagnose and reduces the risk of viral infection or transmission. DNA assay for HBV can detect infection in the windows period, chronic occult infection and can discriminate between active and inactive HBV infection. This cross-sectional study designed to diagnose, analyze HBV infection and to differentiate active from inactive infection based on viral DNA detection. Methods: Blood samples were collected from 256 patients previously diagnosed on the clinical ground as hepatitis B seropositive in Erbil Central Lab. The viral nucleic acid quantitative assessment was done for the collected samples using RT-PCR. Q-square was performed for statistical analysis. Results: Out of 256 collected blood samples 93 (36.3%) showed HBV-DNA positive titers above 50 IU/ml. Among positive subjects, 67 (72.04%) was categorized as inactive carriers (? 2000-20.000 IU/ml HBV-DNA titers). Conclusions: The data produced from this study confirmed the importance of the RT-PCR technique in sensitivity and reliability as a superior diagnostics tool specifically in differentiating active from inactive HBV carriers.
Hepatitis B virus (HBV) is the leading cause of viral hepatitis, as currently over 2 billion people have HBV infection worldwide. Nucleic acid assay and quantitative hepatitis B surface antigen (HBsAg) have been developed for diagnostic and therapeutic monitoring of patients with HBV infection. These tests might also show correlation between HBV DNA and HBs serostatus. The study aimed to find and analyze the frequency and impact of HBsAg seropositivity among patients revealed HBV DNA negative level through quantitative estimation of both seromarkers. Real-time polymerase chain reaction (RT-PCR) and Elecsys assays were used for quantitative estimation of HBV DNA and HBs antigen, respectively. A total of 256 blood samples were used from patients referred for either diagnostic purpose and/or HBV viral load monitoring after antiviral therapy. Blood profile analysis showed 12.26% HBs antigen seropositivity among patients revealed negative for nucleic acid assay for HBV DNA. Positive HBs antigen titers ranged from 1000–50,000 COI, with seronegative anti-HBs antibody test for all samples tested positive for HBs antigen. This study delineated that negative or undetectable quantitation of HBV DNA level does not exclude HBV infection; as the level might fluctuate in different phases of HBV replication. This gives an impression and raising a question about significance of replacing test for HBsAg with quantitation of HBV DNA PCR assay. Thus, the study refers to a special HBV profile outside the classical pattern.
Background and objective: Rheumatoid arthritis is a chronic and inflammatory autoimmune systemic disease of unknown cause that may affect many tissues and organs. Rheumatoid arthritis and thyroid disorders may occur in the patient simultaneously. The main antigens that give rise to thyroid antibodies are thyroglobulin, thyroid peroxidase, anti-cyclic citrullinated protein, and thyroid hormone receptor. This study aimed to determine the frequency of thyroid dysfunction and seroprevalence of anti-thyroid antibody in patients with rheumatoid arthritis and its association with inflammatory marker C-reactive protein. Methods: A cross-sectional study was performed at Rizgari Teaching Hospital and CMC private hospital, Erbil, Iraq. From 15 January to15 October 2020. A hundred patients with rheumatoid arthritis were included in the study, in addition to 70 controls. The serum levels of biomarkers were determined by the chemiluminescent immunoassay method. Results: Patients with rheumatoid arthritis had 6% of thyroid dysfunctions. Regarding the prevalence of thyroid autoantibodies in patients with rheumatoid arthritis, 9% had positive anti-thyroid peroxidase, 13% had positive anti-thyroglobulin, and 6% were positive for a combination of both. There was a statistically significant (P <0.001) high level of serum anti-cyclic citrullinated protein and C-reactive protein in rheumatoid arthritis than in control. Euthyroid profiles were 73% inrheumatoid arthritis patients and 82.9% in control. Conclusion: The study delineated the co-existence of thyroid disorder in rheumatoid arthritis patients with or without autoimmune origin, besides the increased prevalence of auto-thyroid antibody among rheumatoid arthritis with thyroid dysfunction.
Celiac disease (CD) is an immune mediated malabsorption syndrome that occur in genetically susceptible individuals intolerant to dietary gluten. Although considered as a primary gastrointestinal disease, CD is now known to have widespread systemic manifestation.We attempted to define the nature and role of some systemic cytokine that possibly play a role in the pathophysiology of the disease.The sera were collected from those patient suspected of having CD on clinical ground (Newly diagnosed) & then subjected to serologic tests namely anti -tissue transglutaminase IgA, IgG (tTG) & IgA, IgG -Endomysial antibody (EMA).The positive sera for anti -tTG IgA and IgA EMA autoantibody above the cutoff level were then subjected to cytokines assessment namely serum interferon gamma (IFN-γ) and interleukin-10 (IL -10) level.The participant groups comprised 50 newly diagnosed (ND) CD, 20 patients on gluten free diet (GFD) and 20 apparently healthy CD free control (These groups were subjected to the above parameters).The results of the present study among the newly diagnosed cases reveals antitTG IgA and IgA -EMA seropositivity in 15.1 % of the total 330 sera examined ;with anti-tTG IgG & IgG -EMA seronegativity (below the cut-off ) in all sera tested. The highest percent distribution of anti-tTG IgA and IgA -EMA seropositivity was at the serum concentration of 20-29 (36 % & 34 % respectively).A significant decrease (P˂ 0.01) was observed in the mean concentration of antitTG IgA and IgA-EMA between newly diagnosed CD and patients on GFD.
