Cím:Predictors of relapse in patients with ulcerative colitis in remission after one-year of infliximab therapy / Klaudia Farkas, Péter László Lakatos, Ferenc Nagy, Zoltán Szepes, Pál Miheller, Mária Papp, Károly Palatka, Anita Bálint, Renáta Bor, Tibor Wittmann, Tamás Molnár

Megjegyzések:Abstract Background. Some of the most important questions relating to the use of biological therapy in inflammatory bowel diseases concern the duration of maintenance therapy. The RASH study revealed that previous use of biological therapy and dose intensification are associated with restarting of biological therapy in Crohn's disease. The aim of the study was to assess the disease course and frequency of relapse of ulcerative colitis (UC) following discontinuation of infliximab in patients with remission and to determine predictive factors for relapse. Patients and methods. Fifty-one UC patients who had achieved clinical remission following 1 year of infliximab therapy and for whom infliximab was then discontinued participated in this prospective observational study. 15.7% of the patients received infliximab before the 1-year period of biological therapy analyzed in the study. Biological therapy was restarted in case of recurrent clinical activity. Data were collected from four Hungarian IBD centers. Results. Thirty-five percent of the patients needed to be retreated with infliximab within 1 year after treatment cessation. Logistic regression analysis revealed that previous biological therapy (p = 0.021) was associated with the need of restarting infliximab. None of the data relating to patients' demographic and clinical characteristics, concomitant therapy and CRP level showed association with the need for restarting biological therapy. Conclusions. Biological therapy was restarted at a median of 4 months after discontinuation in more than every third UC patients who had been in clinical remission following 1 year of infliximab therapy. Response to retreatment with infliximab was favorable in the majority of the patients who relapsed

Cím:Is there any association between impaired health-related quality of life and non-adherence to medical therapy in inflammatory bowel disease? / Gábor Horváth, Klaudia Farkas, Renáta Hollósi, Ferenc Nagy, Zoltán Szepes, Mária Papp, Károly Palatka, Pál Miheller, László Lakatos, Tamás Szamosi, Tibor Nyári, Tibor Wittmann, Tamás Molnár

Megjegyzések:Inflammatory bowel diseases (IBD) have a huge impact on the patients' lives and require continuous medication and long-term medical follow-up. The Short Form Health Survey (SF-36) is a commonly used questionnaire measuring health-related quality of life (HRQOL). Our aim was to evaluate whether HRQOL influences medication adherence and vice versa in IBD patients, and to find relationships between demographic parameters, therapeutic modalities and non-adherence or HRQOL. PATIENTS AND METHODS: Five hundred ninety-two IBD patients treated at six Hungarian tertiary centers were enrolled. Patients completed the SF-36 questionnaire and a medication adherence report scale during their visits. The associations between demographic parameters, HRQOL, different kinds of therapies and non-adherence were analyzed. RESULTS: The most affected dimension was physical functioning and least affected were the social functions. About 42.7% of the patients revealed their HRQOL to be acceptable. About 74.6% of the patients believed that the prescribed medications actually improved their HRQOL. Diarrhea was the most common and most severe symptom during the course of the disease. Non-adherence was reported in 13.4% of the patients. 'Forgetting to take the medication' was the main reason for non-adherence in 67.6% of the cases. Medication adherence was significantly higher among nonsmoker patients, and also in the case of immunomodulator therapy. There was no association between the sum of HRQOL and different subscores and non-adherence. CONCLUSION: Inflammatory bowel disease is associated with low HRQOL, which is not affected by drug therapy. The impaired quality of life in IBD is mainly influenced by the disease itself.

Cím:Changes in the expression and distribution of the inducible and endothelial nitric oxide synthase in mucosal biopsy specimens of inflammatory bowel disease / Károly Palatka, Zoltán Serfőző, Zoltán Veréb, Zoltán Hargitay, Bea Lontay, Ferenc Erdődi, Gáspár Bánfalvi, Zoltán Nemes, Miklós Udvardy, István Altorjay
Dátum:2005
Megjegyzések:The role of nitric oxide (NO) in the pathophysiology of inflammatory bowel disease (IBD) is controversial. The aim of this study was to investigate the expression and localization of nitric oxide synthase isoforms (iNOS, eNOS) in IBD colonic mucosa. MATERIAL AND METHODS: Forty-four patients with IBD (24 ulcerative colitis (UC), 20 Crohn's disease (CD) and 16 controls) were investigated by colonoscopy. iNOS and eNOS in tissue sections was demonstrated by histochemistry (NADPH-diaphorase reaction) and immunohistochemistry. Cell type analysis and quantitative assessment of the iNOS immunoreactive (IR) cells and densitometry of iNOS in immunoblots were also performed. RESULTS: iNOS-IR cells were significantly numerous in inflamed mucosa of UC (64+/-4 cells/mm2) than in CD (4+/-2 cells/mm2). iNOS-IR/CD15-IR cells showed significant elevation in inflamed (i) versus uninflamed (u) UC mucosa (UCu 8+/-3%, UCi 85+/-10%) In CD, the percentage of iNOS-IR/CD68-IR cells was lower in inflamed sites (CDu 23+/-8%, CDi 4+/-3%). Immunoblot of biopsies revealed significant elevation of iNOS in active UC compared with uninflamed sites, whereas in CD no significant changes were detected. Differences were observed in eNOS and endothelial marker CD31 immunoreactivity. In patients with UC and in controls the ratios of eNOS/CD31-IR vessels were 82.3% and 92.0% respectively, whereas in CD the ratio was 8.3% with a concomitantly significant increase of CD31-IR vessels. The distribution and morphological characteristics of the NOS-IR inflammatory cells and endothelia were similar to those showing NADPH-diaphorase reactivity. CONCLUSIONS: Differences observed in the expression and distribution of NOS isoforms in immune and endothelial cells may contribute to better understanding of the structural and physiological changes in UC and CD.
