Abstract: BACKGROUND: The poor prognosis of rheumatoid arthritis (RA) can be aggravated by the concomitant presence of chronic hepatitis C virus (HCV) infection and there are no guidelines for the treatment of patients affected by both conditions. OBJECTIVE: To propose new therapeutic strategies for patient affected by RA and concomitant HCV chronic infection. METHODS: Review of the literature on the usage of cyclosporine-A (CsA) and anti-tumour-necrosis-factor (TNF)-alpha agents for the treatment of patients affected by RA and HCV. RESULTS/CONCLUSION: CsA exerts an inhibitory effect on HCV replication and it is safe in patients affected by RA and HCV. Anti-TNF-alpha agents are safe and efficacious in patient with RA and HCV. Anti-TNF-alpha and CsA can be safely given in combination in RA patients with HCV infection.

Abstract: Because of the relatively high prevalence of both hepatitis C virus (HCV) infection and autoimmune disorders (ADs), it is not rare to encounter in daily clinical practice patients with ADs also carrying HCV. Corticosteroids and/or immunosuppressant drugs are needed to treat ADs, but they place HCV-infected patients at risk of worsening the infection. So, rheumatologists have often refrained from using corticosteroids or immunosuppressants in AD when HCV-RNA is also present. Cyclosporin A (CsA) is an immunosuppressive agent used to treat a wide range of ADs, but there is a large evidences in the literature, both in vitro and in vivo, suggesting that CsA also exerts an inhibitory effect on HCV replication at standard therapeutic dose. Therefore, this evidence has opened new ways to improve the therapy and the prognosis in patients with HCV-related liver diseases, including those with transplants. Recent reports, although limited in number, also suggest the safety of CsA in the treatment of patients with AD and concomitant HCV infection. In this review we also report our personal experience on the combination treatment with CsA and anti-TNF-alpha agents in rheumatoid arthritis.

Abstract: Cartilage oligomeric matrix protein (COMP) is a tissue-specific noncollagenous protein that was first detected in the serum and the synovial fluid of patients suffering from rheumatic disorders, such as rheumatoid arthritis, reactive arthritis, juvenile chronic arthritis, and osteoarthritis. In this review, the authors consider serum COMP levels in different diseases and discuss their study of patients with rheumatoid arthritis treated with anti-TNF-alpha, to evaluate whether COMP is able to predict a rapid and sustained clinical response to these drugs. They observe that patients with high COMP levels have a lower ACR 70 response independently of the state of systemic inflammation, and conclude that COMP seems to have a pathogenetic role that is independent of the mechanisms regulating inflammatory processes.

Abstract: Due to the relatively high prevalence of both HCV infection and autoimmune disorders (AD), it is not rare to encounter patients with AD also carrying HCV. Considering that the use in HCV infected individuals of corticosteroids or immunosuppressant drugs, that are indeed needed to treat AD, is considered a risk for worsening the clinical outcome of HCV infection, rheumatologist have often refrained from using these drugs in AD when HCV-RNA is also present. Cyclosporine (CsA) is an immunosuppressive agent used to treat a wide range of autoimmune disorders but there is in literature a large body of evidence suggesting that CsA also exerts an inhibitory effect on HCV replication at standard therapeutic dose. The anti-HCV effect of CsA has been demonstrated both in vitro and in vivo. Therefore, these evidences have opened new ways to improve the therapy and the prognosis in patients with HCV-related liver diseases including transplanted ones. Recent reports, although limited in number, also suggest the safety of CsA, in the treatment of patients with AD and concomitant HCV infection. Good results have also been obtained in the treatment in rheumatoid arthritis patients even in association with anti-TNF agents.

Abstract: The discovery of extracellular nucleic acids in the circulation was firstly reported in 1948. In the last few years it has been demonstrated that the entire spectrum of genetic changes seen in primary tumors could also be detected in the serum of patients with solid tumors. This observation has also opened up exciting possibilities for tumor detection and monitoring. More recently investigators started looking for other forms of non-host DNA in the plasma/serum so that in 1997 the presence of fetal DNA in the plasma/serum of pregnant women was demonstrated. This finding suggested that maternal plasma fetal DNA would be a very valuable material for noninvasive prenatal diagnosis and monitoring. It has been also postulated that the presence of the two-way trafficking of nucleated cells and free DNA between the mother and fetus may have potential implications for the development of certain autoimmune diseases. Concerning autoimmune disorders, Tan was the first author to describe the presence of high levels of circulating DNA in patients with systemic lupus erythematosus (SLE) in 1986. Later on different authors demonstrated that elevated levels of serum DNA was also present in patients with other diseases including rheumatoid arthritis. We have analyzed both circulating free DNA and DNA extracted from nucleated blood cells in scleroderma and in lupus patients but, by using gel electrophoresis, we were able to define the pattern of the DNA, instead of simply dosing its amount in the circulation. We have found that SLE and SSc have anomalous patterns of DNA both in serum and in the Buffy-coat and that these patterns are typical for each disorder. It is possible that understanding the biological significance of the diversity in DNA pattern exhibition in white blood cells may give new insights into the pathophysiology of autoimmune disorders. It is also conceivable that circulating and immune-competent cellular DNA markers might offer the promise of precise quantitative analysis useful for diagnostic purposes, without the need to establish difficult cutoffs as is necessary for protein markers.

Abstract: This study further expands our previous observation demonstrating the usefulness of combination therapy of anti-TNF-alpha and cyclosporine A in the treatment of rheumatoid arthritis and concurrent hepatitis C virus infection, as well its efficacy and safety in controlling HCV viremia and liver toxicity. Seven patients were included in the study; transaminase levels remained unchanged, HCV RNA serum levels decreased significantly and DAS 28 significantly improved after twelve month follow-up. No side effects were registered.

Abstract: OBJECTIVE: To test whether an association between HCV genotype, HLA class II alleles distribution and extra-hepatic manifestations (EHM ) can be demonstrated in a group of Italian patients with chronic HCV infection . METHODS: Sixty patients affected by HCV infection with EHM were consecutively enrolled. 163 HCV patients without EHM were tested as controls for the prevalence of HCV genotypes, while we referred to literature as to the controls for HLA distribution. HCV-RNA was quantified by a RT-PCR. HLA class II alleles typing was performed using a standard microlymphocytotoxicity assay. We used chi-square or Fisher test (p<0.05 significant). Odds Ratio (OR) was performed by 2X2 contingency table. RESULTS: HCV 2c genotype was found in 63.46% of patients compared to 19.63% of controls (p<0.0001; OR=7.11). Furthermore, it correlated with carpal tunnel syndrome (p=0.03; OR=4.5) and autoimmune thyroiditis (p=0.02; OR=9.2). On the contrary, 1b genotype protected from EHM in toto (p=0.0004; OR=0.21) and particularly from carpal tunnel syndrome (p=0.0014; OR=0.07). Moreover, 3a genotype prevented HCV people from having cryoglobulinemia (p=0.05; OR=0.11). As to HLA, DR6 seemed to facilitate EHM in HCV patients (p=0.041; OR=1.61), while DQ2 (p=0.03; OR=0.5) and DQ3 (p=0.002; OR= 0.5) may play a protective role. In addition, HLA DR3 was associated with cryoglobulinemia (p=0.02; OR=9.5). CONCLUSIONS: According to our findings, 2c genotype can be considered as a major risk factor for developing HCVrelated EHM, while 1b genotype seems to prevent their onset; there are also evidences suggesting that HLA might play a role in chronic HCV infected patients.

Abstract: The aim of this study was to evaluate serum biomarkers, used in clinical routine, to predict the American College of Rheumatology (ACR) response to long-term anti-TNF alpha treatment (adalimumab). Sera from 29 consecutive rheumatoid arthritis patients were analysed for anti-cyclic citrullinated peptide (anti-CCP), cartilage oligomeric matrix protein (COMP) and IgM and IgA RFs (class-specific rheumatoid factors) at the start of treatment with adalimumab and after 3, 6 and 12 months. The response to the therapy was evaluated by ACR 20, 50, 70 and by DAS 28 scores. The mean serum COMP level of the population did not change after treatment. However, patients with low serum COMP levels (<10 U/l) at baseline showed a significant (p<0.02) higher ACR70 response (>50%) within 3 months, and also at 6 months, than patients with higher COMP values (ACR70<20%). This was also reflected by significantly higher decrease in DAS score at 3 (p<0.02) and 6 months (p<0.01) treatments. The IgM RF titre decreased significantly (p=0.02) after the therapy, but the percentage of serum positivity for anti-CCP and IgA/IgM RF did not change. No significant correlation was shown between serum COMP levels and C-reactive protein/erythrocyte sedimentation rate during the follow-up. Neither were any correlations shown between ACR/DAS 28 scores and anti-CCP, Ig M/IgA RFs. Our data indicate that low (<10 U/l) serum COMP before starting anti-TNF alpha treatment predicts a rapid (within 3 months) and high ACR70 response compared to RA patients with higher COMP values. This might reflect different mechanisms in the cartilage process in the RA disease at that time of treatment with different therapeutic sensitivity to anti-TNF alpha treatment.

Abstract: We describe two cases of rheumatoid arthritis (RA) patients and concomitant hepatitis C virus infection (HCV), treated with cyclosporine A (CsA) and anti-TNF-alpha agents. SGOT/SGPT and HCV-RNA serum levels remained unchanged longer than 1 year of treatment. No side effects were registered. We suggest that combination therapy with CsA and TNF-alpha blockers should be considered safe and well-tolerated in the treatment of HCV-positive RA patients.
