Interpretation of inflammatory markers in lung cyst hydatid disease.

Abstract

Studies on alterations in inflammatory markers and risk factors for perforation in hydatid cysts of the lung are rare. In our study, we planned to investigate the effect of inflammatory markers on prognosis of hydatid cyst disease. 37 patients underwent surgery for pulmonary hydatid cyst between February 2022 and October 2023 and analyzed retrospectively. Inflammatory markers were calculated from preoperative and postoperative 3rd-month peripheral blood results. Cyst size was 58.5 ± 28.0mm, 5 patients had bilateral cysts and 11 patients had multifocal cysts. Preoperative white blood cell, white blood cell difference, preoperative and postoperative eosinophils, preoperative neutrophils, neutrophils difference, preoperative systemic immune inflammatory index, systemic immune inflammatory index difference and preoperative eosinophil lymphocyte ratio were higher in patients with perforated cysts, the cut-off value for preoperative white blood cell for perforation was 10,535, preoperative cut-off value for eosinophils was 230, preoperative cut-off value for neutrophils was 8815, the cut-off value for preoperative systemic immune inflammatory index was 1129.83 and the cut-off value for preoperative eosinophil-lymphocyte ratio was 0.09. In patients with preoperative eosinophil, neutrophil, white blood cell, eosinophil-lymphocyte ratio and systemic immune inflammatory index values above the cut-off value, the probability of perforation increased 7.5, 13.6, 6.3, 9.6, and 9.3 times, respectively.
