Abstract:
Objective To investigate the association between cavitary pulmonary tuberculosis and im-munonutritional status in the Kangbei Plateau and construct a prediction model.Methods A total of 121 pa-tients with active pulmonary tuberculosis treated at Ganzi County People's Hospital from June 2023 to June 2024 were retrospectively enrolled and divided into cavitary group(n=53)and non-cavitary group(n=68)based on imaging findings.Clinical and laboratory data were collected.Influencing factors for pulmonary cavi-tation in tuberculosis were screened using univariate and multivariate logistic regression analysis to construct a prediction model.The model's performance was evaluated using receiver operating characteristic(ROC)curve analysis and the Hosmer-Lemeshow test.Results The cavitary group had higher proportions of smokers,spu-tum-positive cases,patients with disease duration>6 months,and patients with respiratory symptoms at ini-tial diagnosis,as well as higher neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),neutrophil count,and platelet count than the non-cavitary group(P<0.05).Conversely,the prognostic nutri-tional index(PNI),lymphocyte count,and albumin(ALB)level were lower in the cavitary group(P<0.05).Multivariate analysis identified disease duration,NLR,and ALB as influencing factors for pulmonary cavitation in tuberculosis patients(P<0.05).The prediction model yielded an area under the curve(AUC)of 0.909,and the Hosmer-Lemeshow test indicated good model fit(χ2=10.740,P=0.217).Conclusion Pulmonary cavitation in high-altitude tuberculosis patients is associated with disease duration,ALB,and NLR.The com-bined predictive value of these three indicators is high.
