Amaç: Bu çalışma, sistemik bağışıklık-inflamasyon indeksi (SII) ve sistemik inflamatuar yanıt indeksi (SIRI) gibi bileşik inflamasyon indeksleri ile dirençli hipertansiyon arasındaki ilişkiyi araştırarak, bunların öngörücü performansını ve klinik yararını değerlendirmiştir.
Materyal ve metod: Nisan 2022'den Ocak 2025'e kadar yürütülen bu karşılaştırmalı kesitsel çalışmaya, 256'sı kontrollü hipertansiyon (HT) ve 244'ü dirençli hipertansiyon (RHT) olan 500 hipertansif hasta dahil edilmiştir. SII ve SIRI, tam kan sayımlarından hesaplanmıştır. Çok değişkenli lojistik regresyon, çeyrek analiz, kısıtlı kübik spline modelleme ve alıcı işletim karakteristiği (ROC) eğrisi analizi gerçekleştirildi.
Bulgular: RHT hastaları, anlamlı olarak yüksek SII (480,2'ye karşı 361,7, P<0,001) ve SIRI (0,73'e karşı 0,46, P<0,001) değerleri gösterdi. Çok değişkenli analiz, SIRI'yi RHT'nin en güçlü bağımsız öngörücüsü olarak belirledi (OR=25,954, %95 CI: 7,382-91,253, P<0,001). Çeyrek analizinde, RHT prevalansının SIRI çeyrekleri arasında %20,0'dan %84,0'a çıktığı (trend için P<0,001) bir doz-yanıt ilişkisi ortaya çıktı. SIRI, 0,6071'lik optimal kesme değeriyle (duyarlılık %68,0, özgüllük %75,8) mükemmel bir tanı performansı (AUC=0,780, %95 CI: 0,739-0,820) sergilemiştir. Cinsiyete göre tabakalandırılmış analiz, erkeklerin yüksek inflamatuar indekslere daha duyarlı olduğunu göstermiştir.
Sonuç: SII ve SIRI, dirençli hipertansiyonda önemli ölçüde yükselir ve güçlü, maliyet etkin prediktif biyomarkerler olarak işlev görür. SIRI (kesme değeri ≥0,6071) mükemmel bir tanı performansı sergiler ve hipertansif hastalarda risk sınıflandırması, erken teşhis ve hedefe yönelik tedavi stratejilerine rehberlik edebilir.

Aims: Resistant hypertension (RHT) accounts for 10-15% of hypertensive patients, and diagnosis and treatment are more complex in these cases, which means a higher risk of cardiovascular complications. Although the effect of chronic systemic inflammation on the pathophysiology of RHT is known, the effective use of biomarkers is limited. This study investigated the relationship between the Systemic Immune-Inflammation Index (SII) and the Systemic Inflammatory Response Index (SIRI), which are composite inflammatory indices that can be used as markers of chronic inflammation, and RHT, testing their clinical utility and predictive value.
Methods: Between April 2022 and January 2025, 256 hypertensive patients followed up at our clinic were defined as having controlled hypertension (CHT) and 244 as having RHT, for a total of 500 patients included in this cross-sectional study. SII and SIRI values were calculated from routine blood count results. Data were analyzed and compared using multivariate logistic regression, quartile analysis, limited cubic spline modeling, and receiver operating characteristic (ROC) curve analysis.
Results: Significantly higher SII (480.2 vs. 361.7, p<0.001) and SIRI (0.73 vs. 0.46, p<0.001) values were observed in RHT patients. According to multivariate analysis, SIRI stood out as the strongest independent predictor of RHT (OR=25.954, 95% CI: 7.382-91.253, p<0.001). Quartile analysis showed a linear relationship, with RHT prevalence increasing from 20.0% to 84.0% across SIRI quartiles (p<0.001 for trend). SIRI showed attractive diagnostic performance (AUC=0.780, 95% CI: 0.739-0.820) with an optimal cutoff value of 0.6071 (sensitivity 68.0%, specificity 75.8%). Analysis stratified by gender suggested that males may be more sensitive to chronic inflammatory indices.
Conclusion: SII and SIRI are significantly elevated in the RHT patient group. Furthermore, their cost-effectiveness may highlight the existence of biomarkers that can be used as markers of inflammation in the course of this disease. SIRI (cut-off value ≥0.6071), demonstrating superior diagnostic performance, may play a helpful role in the management of hypertensive patients, particularly in the diagnosis of RHT. Furthermore, risk classification may empower clinicians in early diagnosis and targeted treatment strategies.
