    The prognostic value of HALP, SII, and SIRI scores in patients with acute calculous cholecystitis
    (2026) Dolanbay, Turgut; Demir, Bilgehan; Gonultas, Fatih; Gökçe, Hasan; Nogay, Süleyman; Özkan, Asiye; Kaya, Davut
    Acute cholecystitis (AC) is a common surgical emergency, usually developing secondary to gallstones and characterized by gallbladder inflammation. Although classical biomarkers such as leukocyte count and C-reactive protein (CRP) are widely used for diagnostic purposes, composite inflammation-based indices such as Hemoglobin, albümin, lenfosit ve trombosit (HALP), Systemic immune-inflammation index (SII), and Systemic Inflammatory Response Index (SIRI) have recently emerged as important prognostic markers. This study aims to evaluate the association of HALP, SII, and SIRI scores with clinical outcomes [hospital length of stay, Internal care unit (ICU) requirement, and gallstone presence] in adults hospitalized with acute cholecystitis. A total of 88 patients hospitalized with acute cholecystitis between January 2020 and December 2024 were included. Demographic data, admission laboratory parameters, and HALP, SII, and SIRI scores were retrospectively analyzed. Correlation tests and Receiver Operating Characteristic (ROC) analysis were performed to assess prognostic performance. No statistically significant association was observed between HALP, SII, and SIRI scores and either length of hospital stay or intensive care unit requirement (p>0.05). In contrast, WBC levels showed a positive correlation with both parameters and were significantly higher in patients requiring intensive care (p=0.035). In ROC analysis, the Area Under the Curve (AUC) value for Leukocyte (WBC) was determined as 0.859. The significant increase in CRP and glucose levels in patients with acute cholecystitis acalculus suggests that this variant is associated with a more pronounced inflammatory process. In this study, traditional biomarkers especially WBC were more predictive of prognosis in acute cholecystitis than composite inflammation scores. Further time-series, prospective, and multicenter studies are warranted to validate the clinical utility of indices such as HALP, SII, and SIRI.

    The Role of Blood Parameters and Inflammatory Scoring Systems in Prognostic Prediction in Pediatric Appendicitis Patients
    (Wiley, 2026) Nogay, Suleyman; Gonultas, Fatih; Dolanbay, Turgut; Demir, Bilgehan; Bayrakci, Ercan; Gol, Murat; Ongenli, Omer Faruk
    Background: Acute appendicitis is one of the most common surgical emergencies in childhood. Its clinical management poses particular challenges in younger age groups. Blood parameters and inflammatory scoring systems have recently been investigated as promising biomarkers for prognostic prediction. However, the number of studies addressing this issue in the pediatric population remains limited. Methods: This study was conducted retrospectively, and pediatric patients diagnosed with acute appendicitis were included. Hematological parameters (WBC, HGB, NEU%, LYM, and PLT), biochemical markers (ALB, CRP, and GLC), and inflammatory indices (NLR, LAR, HALP, SII, SIRI, and WAR) were analyzed. The findings were evaluated in relation to complications (perforation, abscess, and mesenteric inflammation), length of hospital stay, and appendiceal diameter measured by ultrasonography. ROC analyses were performed to assess prognostic factors. Results: The HALP score was found to be significantly higher in patients without perforation (p = 0.048). NEU%, NLR, and SII values were elevated in patients with abscess formation, whereas LYM, LAR, and HALP were higher in those without abscess (p < 0.05). HGB, ALB, and HALP levels were significantly higher in patients without mesenteric inflammation, indicating an inverse relationship with the severity of inflammation. No correlation was observed between blood parameters and length of hospital stay; however, a weak but significant positive correlation was found among WBC, HGB, NEU%, NLR, SII, SIRI, and appendiceal diameter. ROC analysis demonstrated that HGB and HTC had moderate discriminative ability for mesenteric inflammation (AUC = 0.70), whereas GLC, NLR, and SII showed strong discriminative performance for abscess prediction (AUC = 0.84, 0.88, 0.93). Conclusion: Our findings suggest that HALP, NLR, and SII may hold prognostic value in pediatric patients with appendicitis. However, these parameters alone are insufficient and should be interpreted in conjunction with clinical and imaging findings. Validation of the results in larger, multicenter studies is required.
