CT characteristics of type 2 diabetes mellitus complicated with pulmonary tuberculosis and its relationship with HbAlc level / 中国基层医药

ABSTRACT

Objective To analyze the CT features of type 2 diabetes mellitus complicated with pulmonary tuberculosis and its relationship with glycosylated hemoglobin (HbAlc) level.Methods A total of 120 patients with type 2 diabetes mellitus complicated with pulmonary tuberculosis were selected from January 2015 to January 2017 in the Second Hospital of Datong Coal Mine Group LTD.According to the level of HbA1 c,the patients were divided into three groups,of which A group(HbA1c ＜ 7％) 32 cases,B group(HbA1c,7％ ～ 9％)40cases,C group (HbA1c ＞9％)48cases.MSCT examinations were performed before treatment and 6 months after treatment.The morphological characteristics and therapeutic effects of pulmonary lesions were compared among the three groups.Results The mean lesiondiameter of C group [(6.1 ± 2.1) cm] was significantly higher than that of A group [(3.4 ± 1.2) cm] and B group [(4.3 ± 1.7) cm],which of B group was significantly higher than that of A group,the differences were statistically significant (t =9.478,6.735,3.039,all P ＜ 0.05).The large shadow (83.3 ％),multiple cavities (83.3 ％),and cavitation(75.0％) in C group were significantly higher than those in A group and B group,which in B group were significantly higher than those in A group,the differences were statistically significant(x2 =9.525,7.018,6.865,all P ＜ 0.05).The proportion of lymph node enlargement in C group(83.3％) was significantly higher than that in A group,the difference was statistically significant(x2 =4.444,P ＜ 0.05).After 6 months of standardized anti tuberculosis treatment,the effective rate of C group(68.8％) was significantly lower than that of B group(85.0％)and A group (100.0％),which of B group was significantly lower than that of A group,the difference were statistically significant (x2 =5.236,12.308,3.171,all P ＜ 0.05).Conclusion The CT features of type 2 diabetes mellitus complicated with pulmonary tuberculosis are closely related to the level of HbAlc.With the increase of HbAlc level,the diameter of lung lesions increased and invasively increased.
