Objective: To evaluate the effect of biological (bDMARD) and targeted synthetic (tsDMARD) disease-modifying antirheumatic drugs on the risk of serious infections (SI) and to identify associated risk factors in patients with rheumatoid arthritis (RA).

Materials and Methods: This retrospective cohort study included RA patients followed at a single tertiary care center between August 2018 and August 2024. Patients meeting the ACR/EULAR 2010 criteria were divided into three groups: those receiving b/tsDMARDs (n=199), those receiving only conventional synthetic DMARDs (csDMARDs) (n=50), and healthy controls (n=50). SI was defined as infections requiring hospitalization. Demographic, clinical, and treatment data were collected from electronic medical records. Multiple logistic regression analysis was used to analyze risk factors. ROC curve analysis was performed to evaluate the effect of treatment duration. Statistical analyses were performed using SPSS version 27 (IBM).

Results: SI occurred in 15.8% (n=31) of patients in the b/tsDMARD group, compared to 14% (n=7) in the csDMARD group and 4% (n=2) in the control group. b/tsDMARD use significantly increased the risk of SI compared to healthy controls (OR: 3.66; 95% CI: 1.09-12.28; p=0.035), but no significant difference was found compared to the csDMARD group (p=0.781). In multiple regression analysis, advanced age (p=0.005) and prolonged b/tsDMARD use (p=0.014) were identified as independent risk factors for SI. ROC analysis identified 57.5 months of treatment duration as a threshold value for SI risk (Area Under the Curve: 0.624; p=0.023). Treatment duration exceeding this threshold increased the risk by 1.175-fold (p=0.009). Among drugs, rituximab use was associated with a higher risk of SI compared to other agents (OR: 1.72; p=0.005). Pneumonia was the most common site of SI.

Conclusion: b/tsDMARD therapy increases the risk of SI in RA patients, particularly with prolonged use and in advanced age. The risk may vary among different biological agents; in our study, rituximab was associated with a higher risk. These findings emphasize the importance of personalized risk-benefit assessment and close monitoring for infections in RA management.

Biyolojik ve Hedefe Yönelik Sentetik DMARD Kullanan Romatoid Artrit Hastalarında Ciddi Enfeksiyon Riski: Tek Merkezli, Retrospektif Bir Kohort Çalışması

Amaç: Biyolojik (bDMARD) ve hedefe yönelik sentetik (tsDMARD) hastalığı modifiye edici antiromatizmal ilaçların ciddi enfeksiyon (SI) riski üzerindeki etkisini değerlendirmek ve romatoid artrit (RA) hastalarında ilişkili risk faktörlerini belirlemek.

Gereç ve Yöntemler: Bu retrospektif kohort çalışmasına, Ağustos 2018 ile Ağustos 2024 tarihleri ​​arasında tek bir üçüncü basamak sağlık merkezinde takip edilen RA hastaları dahil edildi. ACR/EULAR 2010 kriterlerini karşılayan hastalar üç gruba ayrıldı: b/tsDMARD alanlar (n=199), yalnızca konvansiyonel sentetik DMARD (csDMARD) alanlar (n=50) ve sağlıklı kontroller (n=50). SI, hastaneye yatış gerektiren enfeksiyonlar olarak tanımlandı. Demografik, klinik ve tedavi verileri elektronik tıbbi kayıtlardan toplandı. Risk faktörlerini analiz etmek için çoklu lojistik regresyon analizi kullanıldı. Tedavi süresinin etkisini değerlendirmek için ROC eğrisi analizi yapıldı. İstatistiksel analizler SPSS sürüm 27 (IBM) kullanılarak yapıldı.

Bulgular: b/tsDMARD grubundaki hastaların %15,8'inde (n=31) SI meydana gelirken, csDMARD grubunda bu oran %14 (n=7) ve kontrol grubunda %4 (n=2) idi. b/tsDMARD kullanımı, sağlıklı kontrollerle karşılaştırıldığında SI riskini önemli ölçüde artırdı (OR: 3,66; %95 CI: 1,09-12,28; p=0,035), ancak csDMARD grubuyla karşılaştırıldığında önemli bir fark bulunamadı (p=0,781). Çoklu regresyon analizinde, ileri yaş (p=0,005) ve uzun süreli b/tsDMARD kullanımı (p=0,014) SI için bağımsız risk faktörleri olarak belirlendi. ROC analizi, 57,5 ​​aylık tedavi süresini SI riski için bir eşik değer olarak belirledi (Eğri Altındaki Alan: 0,624; p=0,023). Bu eşiği aşan tedavi süresi, riski 1,175 kat artırmıştır (p=0,009). İlaçlar arasında, rituksimab kullanımı diğer ajanlara kıyasla daha yüksek SI riski ile ilişkilendirilmiştir (OR: 1,72; p=0,005). En sık görülen SI bölgesi pnömonidir.

Sonuç: b/tsDMARD tedavisi, özellikle uzun süreli kullanımda ve ileri yaşta RA hastalarında SI riskini artırmaktadır. Risk, farklı biyolojik ajanlar arasında değişiklik gösterebilir; çalışmamızda rituksimab daha yüksek bir risk ile ilişkilendirilmiştir. Bu bulgular, RA yönetiminde kişiselleştirilmiş risk-fayda değerlendirmesinin ve enfeksiyonlar açısından yakın takibin önemini vurgulamaktadır.
