dc.description.abstractUvod: Reumatoidni artritis (RA) je bolest koja dovodi do ireverzibilnog oštećenja zglobova usled čega je neophodno pri postavljanju dijagnoze započeti lečenje. TNF-alfa inhibitori predstavljaju revolucionarno otkriće u lečenju RA, pri čemu su najčešće korišćeni Etanercept i Adalimumab. Oni nisu efikasni kod svih pacijenata kod kojih se primene, a mehanizmi gubitka odgovora nisu jasni. Cilj rada je odrediti uticaj Etanercepta i Adalimumaba na aktivnost bolesti (merenjem DAS28 SE i DAS28 CRP skora) i funkcionalni status pacijenata (merenjem HAQ-DI upitnika), broj bolnih i otečnih zglobova pre i tokom godinu dana primene ovih lekova, kao i utvrditi povezanost koncentracije Etanercepta i Adalimumaba u krvi sa vrednostima DAS28 SE u momentu odreĎivanja koncentracije leka. Praćena je i učestalost neželjenih efekata kod pacijenata lečenih sa ova dva leka. Ispitan je i uticaj primene Metotreksata na nivoe lekova u krvi, kao i doza Metotreksata pre i 6 meseci nakon uvoĎenja Etanercepta ili Adalimumaba. Metode: Studija je sprovedena u Specijalnoj bolnici za reumatske bolesti i Klinici za nefrologiju i kliničku imunologiju, Kliničkog centra Vojvodine u Novom Sadu i obuhvatila je 88 pacijenata kod kojih je postavljena dijagnoza RA, od kojih je 49 bilo lečeno Etanerceptom, a 39 Adalimumabom. Analizirana je medicinska dokumentacija, a nakon početka primene TNF-alfa inhibitora svim ispitanicima je u toku godinu dana svaka tri meseca raĎena kontrola koja je podrazumevala anamnezu i fizički pregled, analizu biohemijskih nalaza krvi, merena je aktivnost bolesti merenjem indeksa aktivnosti bolesti DAS28 SE i DAS28 CRP i raĎena procena funkcionalnog statusa tako što je pacijent popunjavao HAQ-DI upitnik. Rezultati: Aktivnost RA merena DAS28 SE i DAS28 CRP indeksima, funkcionalni status meren HAQ-DI upitnikom, broj bolnih i otečenih zglobova i vrednosti reaktanata akutne faze značajno su veći pre početka terapije Etanerceptom i Adalimumabom i smanjuje se tokom prvih 6 meseci lečenja ovim lekovima i potom se taj efekat terapije održava do kraja perioda praćenja. Nema statistički značajne razlike u poreĎenju Etanercepta i Adalimumaba u odnosu na učestalost neželjenih dejstava. Doza Metotreksata je statistički značajno manja 6 meseci nakon upotrebe biološkog leka Etanercept i Adalimumab. Pacijenti lečeni Metotreksatom uz Adalimumab imali su statistički značajno veće nivoe leka, nego oni koji ga nisu koristili. Zaključak: TNF-alfa inhibitori ne dovode do zaustavljanja bolesti kod svih pacijenata kod kojih se primene. Mehanizam gubitka odgovora na terapiju TNF-alfa inhibitorima nije jasan. Kako bi se donela najbolja odluka za pacijenta, neophodno je odrediti nivo leka u krvi, kao i nivo antitela na lek prilikom svake promene stanja pacijenta. Za sada nema dovoljno studija koje ukazuju da li postoji veza izmeĎu ekspresije TNF-alfa gena i nivoa TNF-alfa u krvi, te da li bi se merenjem TNF-alfa u krvi mogla korigovati terapija i doza TNF-alfa inhibitora što će verovatno biti predmet budućih istraživanja.sr
dc.description.abstractRheumatoid Arthritis (RA) is a disease that leads to irreversible joint damage, which makes necessary to start treatment when the diagnosis is set. TNF-alpha inhibitors represent a revolutionary discovery in the treatment of RA, and the most commonly used are Etanercept and Adalimumab. They are not effective in all patients, and the mechanisms of loss of response are not clear. The aim of this study is to determine the effect of Etanercept and Adalimumab on disease activity (by measuring DAS28 SE and DAS28 CRP score) and the functional status of patients (by measuring the HAQ-DI questionnaire), the number of painful and swollen joints before and during the first year of administration of these drugs. Also, it was determined a correlation between the concentration of Etanercept and Adalimumab in blood and the values of DAS28 SE at the moment of drug concentration measurement. The incidence of adverse effects in patients treated with these two drugs was also observed. It was examined the effect of Methotrexate on drug levels in the blood as well as the dose of Methotrexate before and 6 months after the introduction of Etanercept or Adalimumab. Methods: The study was conducted at the Special Hospital for Rheumatic Diseases and the Clinic of Nephrology and Clinical Immunology, Clinical Center of Vojvodina in Novi Sad. It included 88 patients with RA, 49 were treated with Etanercept and 39 with Adalimumab. Medical documentation was analyzed, and during the first year of TNF-alpha inhibitor administration, every three months were done anamnesis and physical examination, analysis of blood biochemical findings, measurements of the disease activity with DAS28 SE and DAS28 CRP score and a functional status assessment with the HAQ-DI questionnaire. Results: Disease activity measured by DAS28 SE and DAS28 CRP scores, functional status measured with HAQ-DI questionnaire, number of painful and swollen joints and acute phase reactant values are significantly higher before Etanercept and Adalimumab therapy and decreased during the first 6 months of treatment with these drugs and then this effect of therapy is maintained until the end of the monitoring period. There is no statistically significant difference in the comparison of Etanercept and Adalimumab with respect to the frequency of adverse events. The dose of Methotrexate was statistically significantly lower for 6 months after the use of Etanercept and Adalimumab. Patients treated with Methotrexate and Adalimumab had statistically significantly higher drug levels than those who did not use it. Conclusion: TNF-alpha inhibitors are not effective in all patients who used them. The mechanism of loss of response to TNF-alpha inhibitors is not clear. In order to make the best decision for the patient, it is necessary to determine the drug level in the blood as well as the level of antibodies to the drug in each change in the patient's condition. For now, there are not enough studies to indicate whether there is a link between expression of the TNF-alpha gene and the level of TNF-alpha in the blood, and whether the measurement of the TNF-alpha in blood could be used for therapy correction and change of dose of TNF-alpha inhibitor, which is likely to be the subject of the future research.en
