Evaluation of the C-reactive protein-albumin-lymphocyte (CALLY) index in cases of preterm premature rupture of membranes

Abstract

Aims: This study aimed to evaluate the prognostic significance of the C-reactive protein-albumin-lymphocyte (CALLY) index in pregnancies complicated by preterm prelabor rupture of membranes (PPROM). Methods: This prospective study included pregnant women diagnosed with PPROM who were followed at the Perinatology Clinic of Ankara Etlik City Hospital between December 1, 2024, and March 1, 2025. The PPROM group consisted of 181 women, while 170 healthy pregnant women, matched for maternal and gestational age, served as controls. Maternal and neonatal outcomes, along with laboratory parameters such as CRP, WBC, and the CALLY index, were evaluated. Results: The PPROM group had significantly lower birth weight (2318.6±493.7 g vs. 3014.0±438.1 g, p<0.001) and longer neonatal intensive care unit (NICU) stay (5.0±10.7 days vs. 1.0±2.8 days, p<0.001) compared to the control group. Inflammatory markers, including CRP (11.8±14.9 mg/L vs. 5.5±4.2 mg/L, p<0.001) and WBC (12.9±4.4×10³/µL vs. 10.6±2.2×10³/µL, p<0.001), were significantly elevated in the PPROM group, while the CALLY index was notably lower (18.0±28.1 vs. 31.8±38.6, p<0.001). Neonatal complications were significantly more frequent in the PPROM group, including NICU admission (38.7% vs. 12.4%, p<0.001), fetal distress (10.5% vs. 0.6%, p<0.001), and chorioamnionitis (3.3% vs. 0.0%, p=0.017). The area under the curve (AUC) for the CALLY index was 0.681 (95% CI: 0.626–0.736, p<0.001). Conclusion: The CALLY index was lower in pregnancies with PPROM and showed a fair ability to distinguish PPROM cases from healthy controls. These findings suggest that CALLY may serve as a supportive marker reflecting inflammation in PPROM.
