Abstract

Aim: To investigate the association between fragmented QRS (fQRS) on electrocardiography and the Systemic Immune-Inflammation Index (SII) with disease severity in patients with acute pancreatitis (AP). Methods: This retrospective observational study included 92 patients diagnosed with AP between January 2022 and December 2024. Clinical, laboratory, and electrocardiographic data at admission were analyzed. SII was calculated as platelet count × (neutrophil/lymphocyte). Severe AP was defined as a BISAP score ≥3. Patients were compared according to the presence or absence of fQRS. Multivariable logistic regression analysis was conducted including age, SII, and fQRS. Receiver operating characteristic (ROC) analysis was used to evaluate the predictive performance of SII. Results: Fragmented QRS was detected in 18 patients (19.6%). Patients with fQRS had significantly higher SII values and BISAP scores compared with those without fQRS (p=0.020 and p<0.001, respectively). Severe AP was more frequent in the fQRS-positive group (50% vs 12.2%, p<0.001). ROC analysis demonstrated moderate discriminative ability of SII for predicting severe AP (AUC=0.693). Using the Youden index, a cut-off value of ≥1198 provided a sensitivity of 88.9% and a specificity of 52.7%. The positive predictive value was 31.4% and the negative predictive value was 95.1%. In multivariable analysis, age remained the only independent predictor of severe AP (p<0.001), whereas SII and fQRS did not retain independent significance. Conclusion: The presence of fQRS was associated with higher inflammatory burden and disease severity in AP. Although SII showed moderate discriminative ability for severe disease in ROC analysis, age remained the only independently associated factor in multivariable analysis. These findings suggest that electrocardiographic and inflammatory alterations may reflect overall disease burden rather than act as independent determinants of severity.

Özet

Amaç: Bu çalışmada akut pankreatit (AP) hastalarında elektrokardiyografide fragmente QRS (fQRS) varlığı ile Sistemik İmmün-İnflamasyon İndeksi (SII)’nin hastalık şiddeti ile ilişkisini değerlendirmek amaçlandı. Yöntem: Ocak 2022–Aralık 2024 tarihleri arasında AP tanısı alan 92 hasta geriye dönük olarak incelendi. Başvuru anındaki klinik, laboratuvar ve elektrokardiyografik veriler analiz edildi. SII, trombosit × (nötrofil/lenfosit) formülü ile hesaplandı. Şiddetli AP, BISAP skoru ≥3 olarak tanımlandı. Hastalar fQRS varlığına veya yokluğuna göre karşılaştırıldı. Yaş, SII ve fQRS değişkenleri çok değişkenli lojistik regresyon analizine dahil edildi. SII’nin şiddetli AP’yi öngörme performansı ROC analizi ile değerlendirildi. Bulgular: Fragmente QRS (fQRS) 18 hastada (%19,6) saptandı. fQRS pozitif hastalarda, fQRS negatif olanlara kıyasla SII değerleri ve BISAP skorları anlamlı derecede daha yüksekti (sırasıyla p=0,020 ve p<0,001). Şiddetli akut pankreatit, fQRS pozitif grupta daha sık görüldü (%50’ye karşı %12,2; p<0,001). ROC analizi, SII’nin şiddetli akut pankreatiti öngörmede orta düzeyde ayırt edici güce sahip olduğunu gösterdi (AUC=0,693). Youden indeksine göre ≥1198 kesim değeri %88,9 duyarlılık ve %52,7 özgüllük sağladı. Bu eşikte pozitif prediktif değer %31,4, negatif prediktif değer ise %95,1 idi. Çok değişkenli analizde, yaş şiddetli akut pankreatit için bağımsız prediktör olarak saptanırken (p<0,001), SII ve fQRS bağımsız anlamlılık göstermedi. Sonuç: fQRS varlığı, akut pankreatitte artmış inflamatuvar yük ve hastalık şiddeti ile ilişkili bulundu. SII, ROC analizinde şiddetli hastalığı öngörmede orta düzeyde ayırt edici performans göstermesine rağmen, çok değişkenli analizde bağımsız olarak ilişkili tek faktör yaş idi. Bu bulgular, elektrokardiyografik ve inflamatuvar değişikliklerin bağımsız belirleyicilerden ziyade genel hastalık yükünü yansıtabileceğini düşündürmektedir.
