Platelets as a Possible Reservoir of HCV And Predictor of Response to Treatment
In the era of new Hepatitis C Virus (HCV) therapy, and the detection of
extrahepatic HCV reservoirs such as peripheral blood mononuclear
cells and platelets, it is important to understand the factors underlying
resistance to treatment. Detection and quantitation of HCV-RNA
in platelets or leucocytes from patients under antiviral therapy is
poorly studied and the limited studies generated contradictory
results.
Aim: To detect and quantify HCV-RNA in platelets, and to evaluate
the relation between HCV-RNA in the serum and the kinetics of
HCV-RNA in platelets, in response to treatment.
Method: Viral kinetic was tested in 20 chronic HCV genotype4,
during the course of therapy.
Results: HCV-RNA was detected in sera of all infected patients.
The baseline platelet viral load was significantly lower in responders
compared to non-responders. Platelet viral load was also related to
serum viral load (t=3.39, p=0.001), but not related to platelet count
(t=-0.56, p=0.58). ROC curve analysis revealed that in general,
platelet viral load at different time points was a better predictor of
SVR compared to serum viral load.
Conclusion: HCV RNA analysis in whole blood may be more
sensitive than platelet-poor plasma, which might underestimate
circulating viral load. Early eradication of viremia from platelets is
associated with higher rates of SVR. Our data, reconfirm higher
HCV-RNA levels in serum compared to platelets. Thrombocytopenia
occurring during interferon-based therapy might be a manifestation
of viral eradication rather than adverse effects. Our findings warrant
testing the sensitivity of platelet viral load as a predictor of poor
response
INTERLEUKIN-22 SERUM LEVELS IN PATIENTS WITH RHEUMATOID ARTHRITIS IN SANA'A CITY, YEMEN
Objective: Interleukin (IL) -22 is a novel mediator of a member of IL-10 family cytokines that is produced by many different types of lymphocytes including both those of innate and adaptive immune system. This cytokine has potent proliferative and inflammatory effects on different cell lines. Recently, accumulated data has indicated that IL-22 plays an important role in the pathogenesis of rheumatoid arthritis (RA). We aimed to investigate the levels of IL-22 and its association with demographic, clinical data as well as serological markers in RA.
Methods: IL-22 serum levels were measured in 45 newly diagnosed RA patients without any treatment and 45 healthy individuals as control by a manual Enzyme linked immunosorbent assay (ELISA). Correlations of IL-22 serum levels were sought with demographic, clinical data and serological parameters. IL-22 levels were significantly elevated in serum of RA patients (median= 86.89ng/ml and range = 896) compared to serum of healthy control (median=75.36ng/ml and range=459), p=.022.
Results: The IL-22 levels were correlated positively with C-reactive protein (CRP), anti-cyclic citrullinated peptide (ACCP) antibodies in RA patients. Significant higher levels of serum IL-22 in RA patients compare with those in healthy control.
Conclusion: Highly significant association between serum levels of IL-22 and the serological markers (CRP and ACCP antibodies) in the diagnosis of RA suggest the potential levels of IL-22 as a valuable biomarker for the evaluation of disease severity in RA patients.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

SEROPREVALENCE OF ANTI-MANNOSE BINDING LECTIN AUTOANTIBODIES IN PATIENTS WITH RHEUMATOID ARTHRITIS IN SANA'A CITY- YEMEN
Objective: Rheumatoid arthritis (RA) characterized by synovial inflammation and destruction of cartilage and bone. Until now there is no single test that diagnoses RA, however, several blood tests may suggest the presence of this disease. RA is associated with the presence of a number of autoantibodies as such as rheumatoid factor (RF), anti-cyclic citrullinated peptide (ACPA) and anti-mannose binding lectin (anti-MBL). This study aimed firstly to investigate the presence of anti-MBL autoantibodies in the sera of RA patients and healthy controls and secondly to determine the diagnostic value of this marker in comparison with the classical RF, C- reactive protein (CRP) and ACPA among RA cases.
Methods: This case-control study was conducted at four health establishments; two public (Al-Thawra Modern General Hospital and National Center of Central Public Health Laboratories) and two private (University of Science and Technology Hospital and Aulqi Specialized Medical Laboratories) in Sana'a city. Ninety-four individuals were enrolled in this study. Forty-seven persons were clinically diagnosed to have RA by a rheumatologist and 47 healthy subjects without RA were used as controls. Sera were separated and tested for presence of serum anti-MBL autoantibodies, ACPA, RF and CRP by a commercially available enzyme linked immunosorbent assay (ELISA) and latex agglutination technique.
Results: Study results showed that the mean±SD for the levels of serum anti-MBL autoantibodies among RA cases were 394±243 ng/ml which were significantly higher than that recorded among healthy controls (217±173 ng/ml). The levels of serum anti-MBL autoantibodies were associated with positive RF and CRP tests (p=.02 and .007 respectively), but not with positive ACPA test (p=.42).
Conclusion: The result of this study showed higher levels of serum anti-MBL autoantibodies among RA cases comparing with the healthy controls and reveal an association with positive results for RF and CRP, but not with ACPA. Therefore, the anti-MBL antibody levels may associated with systemic autoimmune diseases and might not exclusive to RA.
