Abstract：Objective To explore the impact of hypocholesterolemia on pneumonia in pulmonary tubercu-losis.Methods Data of 600 patients who were diagnosed with pulmonary tuberculosis in Guangzhou chest hospital were collected.Of these patients,300 were combined with pneumonia(experimental group)and the other subjects were pulmonary tuberculosis only(control group). Parameters including age,gender,sputum tubercle bacilli state,alanine aminotransferase(ALT),aspartate aminotransferase(AST),serum creatinine(Scr),blood urea ni-trogen(BUN),hemameba(WBC),c-reactive protein(CRP),procalcitonin(PCT),serum albumin(ALB),hemo-globin(HB),total of blood lymphocytes(TLC),and plasma total cholesterol(TC)between the 2 groups were com-pared. The correlation between hypocholesterolemia and the severity of pneumonia estimated with CURB-65 score was analyzed. Results hypoproteinemia,low lymphocyte and(all P < 0.05)were identified as risk factors for pneumonia with univariate logistic regression(all P<0.05).Moreover,hypocholesterolemia was confirmed as inde-pendent risk factor in mulitvariate logistic model(P < 0.05). The TC concentration was negatively correlated with CURB-65 score and significantly different among low-risk(CURB-65 score of 0-1),moderate(CURB-65 score of 2)and high risk(CURB-65 score of 3-5)pneumonia groups(all P < 0.05). Conclusions Hypocholesterolemia was an independent risk factor for pneumonia in pulmonary tuberculosis patients. The decreased level of TC was parallel with the severity of pneumonia.
