Öğe Biological and targeted-synthetic disease-modifying anti-rheumatic drugs with concomitant methotrexate or leflunomide in rheumatoid arthritis: real-life TReasure prospective data(Clinical & Exper Rheumatology, 2021) Kimyon, G.; Kalyoncu, U.; Kiraz, S.; Bes, C.; Coskun, N.; Yagiz, B.; Kucuksahin, O.Objective To determine the real-life efficacy, safety, and drug-retention rates of leflunomide (LEF) or methotrexate (MTX) as a synthetic DMARD used in combination with biological DMARDs for rheumatoid arthritis (RA). Methods The TReasure database is a web-based, prospective, observational cohort of RA and spondyloarthritis patients from 17 centres in different regions of Turkey and data entry was enabled since December 2017. Until May 2019,2556 RA patients on biologic treatment were recorded. Demographic and RA-related data of 1526 patient either received LEF or MTX were compared, efficacy of both drugs compared by RA-disease activity composite indices. Reasons fordrug discontinuation also recorded. Drug retention rates were compared with Kaplan-Meier curves (log-rank test). Results Of 2556 RA patients 1526 (59.7%) were receiving concomitant LEE (n=646, 42 3%; median follow up 35 months) or concomitant MTX (n=880, 573%; median follow-up 32 months) at the time of initiation to their first bDMARDs. The LEE group were older and had longer disease duration, proportion of females and seropositive patients was higher in this group. In the LEE group, non-anti-TNF agents were used in higher rate. Remission rates, changes in composite indices and rate of comorbidities and adverse events were similar in both groups. The retention rate of LEE + non-anti-TNF b/tsDMARDs was higher compared to MTX + anti-TNF bDMARDs (p=0.002, log-rank). Rates of adverse events were similar in both groups. Conclusion LEE in combination with either anti TNF or non anti DIF drugs appears as an effective and safe therapeutic option at least as MIX.Öğe Biological and targeted-synthetic disease-modifying antirheumatic drugs with concomitant methotrexate or leflunomide in rheumatoid arthritis: Real-life TReasure prospective data(Clinical and Experimental Rheumatology S.A.S., 2021) Kimyon, G.; Kalyoncu, U.; Kiraz, S.; Bes, C.; Coskun, N.; Yagiz, B.; Kucuksahin, O.Objective To determine the real-life efficacy, safety, and drug-retention rates of leflunomide (LEF) or methotrexate (MTX) as a synthetic DMARD used in combination with biological DMARDs for rheumatoid arthritis (RA).

S.; Yilmaz, VBackground: Ocular squamous cell carcinomas (OSCCs) in cattle has been studied for many years, but no definite etiology has been established. Squamous cell carcinomas (SCCs) may occur in different body parts of cattle. Depending on the location, it can cause an economic loss of varying degrees. Aims: The aim of this study was to investigate the causes of OSCCs in the eye region of cattle. Methods: Sixty tumoral masses taken form 60 cattle with proliferation in the eye region that were collected between the years 2012-2022 were used. These cases were admitted to our department for routine diagnosis. The tissues were diagnosed as OSCC using histopathological methods. The presence of bovine papillomavirus (BPV), one of the causative factors, was investigated using immunohistochemical and polymerase chain reaction (PCR). Results: Macroscopically masses were nodular or cauliflower-like and fragile and had hemorrhagic surfaces. Considering the keratin pearls, tumoral islands, and squamous differentiation, 20 out of 60 cases were classified as well, 20 as moderately, and 20 as poorly-differentiated OSCCs. 47 of the 60 cases were BPV positive using immunohistochemical methods. However, BPV nucleic acid was detected in only two cases with PCR. Only one of the cases could be sequenced. After phylogenetic analysis, virus strain was identified as BPV-1. Conclusion: Our results indicated that papillomaviruses can contribute to the development of OSCCs, in both precursor lesions and also advanced stage OSCCs. We found that BPV-1 has a possible causative role; however, more studies are needed to investigate the role of other viral agents and their interaction with secondary factors.
