CT Diagnosis Of Pulmonary Tuberculosis Combined With Diabetes And Its Correlation With Fasting Blood Glucose

Objective:To investigate the correlation between CT manifestations of diabetes mellitus with pulmonary tuberculosis and fasting blood glucose level.Methods:192 cases of type 2 diabetes mellitus?T2DM?with primary pulmonary tuberculosis were randomly selected from the Fourth people's Hospital of Huaian City..Based on the fasting blood glucose?Glu?checked on the second day after admission and the 2010 edition of the guidelines for Prevention and treatment of Type?Diabetes in China,patients are divided into three groups:Glu<7 mmol/L for blood glucose control well group?Group I n=34?,the level 7-10 mmol/L for the fairly-controlled group?Group?,n=51?and the level>10 mmol/L for uncontrolled??group,n=107?.The CT signs of various lesions in each group of patients were recorded and compared.Results:The incidence of large lamellar shadow in the three groups was 50%?17/34?,56.8%?29/51?and 84.1%?90/107?.The incidence of large leaf slices in group?was significantly higher than that in group ? and??x²=21.09,p<0.01?,while there is no statistical significance between group ? and group??x²=0.39,p>0.05?,and the incidence of large shadows in the lung and?or?lung lobules in the three groups were increased(x²_{linear trend}=19.27,p<0.05).The incidence of air bronchogram in the three groups was47%?16/34??52.9%?27/51??74.7%?80/107?respectively,which shows the incidence of group?was significantly higher than that in group?and group ??x²=12.33,p<0.01?.There was no significant difference between group?and group ??x²=0.28,p>0.05?.The incidence of air bronchus syndrome in the three groups was increased(x²_{linear trend}=11.33,p<0.05).The incidence of no-wall cavity in three groups was 32.3%?11/34??45%?23/51??63.5%?68/107?,the incidence of group?was significantly higher than that in group ? and group??x²=11.88,p<0.01?,and there was no significant difference between group?and group ??x²=1.38,p>0.05?.The incidence of no-wall cavity in the three groups was increased(x²_{linear trend}=11.70,p<0.05).The incidence of multiple cavities in the three groups was 26.4%?9/34??43.1%?22/51??54.2%?58/107?respectively.The incidence of multiple cavities in group?was significantly higher than that in group ? and group??x²=8.27,p<0.05?,while there was no significant difference between group?and group ??x²=2.45,p>0.05?.The incidence of multiple cavities in the three groups was increased(x²_{linear trend}=8.12,p<0.05).The incidence of thick-wall cavities in the three groups was 26.4%?9/34??33.3%?17/51??84.1%?90/107?respectively.The incidence of group?was significantly higher than that of group?and group ??x²=8.81,p<0.05?,and there was no significant difference between group?and group ??x²=0.45,p>0.05?.The incidence of thick-wall cavities was increased in the three groups(x²_{linear trend}=8.32,p<0.05).The incidence of bronchial tuberculosis in the three groups was23.5%?8/34?,35.2%?18/51?,46.7%?50/107?,in which group?was significantly higher than that in group?and group ??x²=6.34,p<0.05?,and there was no significant difference between group?and group ??x²=1.33,p>0.05?.Three groups of bronchial tuberculosis incidence rate showed an increasing trend(x²_{linear trend}=6.30,p<0.05)).The incidence of the small patchy shadow,proliferative nodules,single cavity,thin-wall cavity,lymph nodes and pleural effusion was not statistically significant?p>0.05?.Conclusion:CT manifestations in diabetic patients with pulmonary tuberculosis was closely related to the level of fasting blood glucose.Accompanied by the high-lever blood glucose,the pulmonary tuberculosis aggravates.Hence,bi-directional monitoring of fasting blood glucose and CT scan can objectively reflect the condition of diabetes mellitus with pulmonary tuberculosis and provide imaging information,therefore to guide clinical diagnosis and further treatment.
