The sensitivity of ST and tuberculin chip (78.3%vs16.7%, P=0.005, 78.3%vs34.7%, P=0.000).TST and tuberculosis protein chip decreased with the decrease of CD4+T lymphocyte count, but IGRA sensitivity was less affected by CD4+T lymphocyte count. When CD4+T lymphocyte count was 50 /u1, the sensitivity of IGRA was significantly higher than that of tuberculosis protein chip. The positive results of 76.6%vs14.3%, P=0.001, 76.6%vs25.0%, P=0.000).IGRA showed that the latent infection rate of tuberculosis in HIV infected persons was 32.6%, the detection rate of Mycobacterium tuberculosis in AIDS combined with tuberculosis was 20.3%, which was significantly lower than that of 48% (P=0.000).HIV positive patients with HIV negative tuberculosis (P=0.000), and the resistance rate of Mycobacterium tuberculosis was 25%, and HIV negative. There was no significant difference in the 25.2% of the patients with sex. The detection rate of Mycobacterium tuberculosis in the patients with fiberoptic bronchoscopy was significantly higher than that of the AIDS patients with pulmonary tuberculosis (51.2%vs17.7%, P=0.000).HIV positive tuberculosis. The erythrocyte sedimentation rate of HIV infected and HIV negative TB patients was 84 (49-117) mm/h, 53 (20-83) mm/h and 24 (13-41) mm/h, there was a significant difference between the three groups (P=0.000).
Conclusion: the clinical manifestation of AIDS combined with tuberculosis is different. It should be based on the medical history, symptoms and signs, imaging examination, immunological examination, erythrocyte sedimentation and pathogenic examination. Some patients still have to carry out comprehensive measures such as diagnostic treatment to make correct diagnosis of.IGRA, which is less affected by the immune function, and has a greater diagnosis of HIV positive tuberculosis. The detection rate of pathogenic bacteria in.HIV positive TB patients was significantly lower than that of HIV negative tuberculosis. The detection rate of Mycobacterium tuberculosis in lymph node and bronchoalveolar lavage fluid was higher. The multi drug resistance and multi drug resistant strains isolated from AIDS patients were relatively more. The fiberoptic bronchoscopy has a greater diagnosis for the difficult patients. Value. Bronchoalveolar lavage fluid for bacterial culture and TB-DNA detection can improve the detection rate of Mycobacterium tuberculosis.

Objective: To explore the diagnostic value of imaging, immunology, bacteriology, fiberoptic bronchoscopy and erythrocyte sedimentation rate (ESR) in AIDS complicated with tuberculosis.
Methods: to collect the imaging results of AIDS patients with tuberculosis, analyze the imaging characteristics of AIDS patients with tuberculosis, and compare with HIV negative tuberculosis. Blood sedimentation for HIV negative TB and AIDS patients with tuberculosis, immunological detection (IGRA, TST and TB chip detection), sputum, secretions and so on. Mycobacterium culture, typing identification and drug sensitivity test were carried out. Fiberoptic bronchoscopy and alveolar lavage were performed on the subjects. The findings of fiberoptic bronchoscopy and the detection rate of Mycobacterium were analyzed.
Results: the imaging features of AIDS combined with tuberculosis were mostly diffuse (57.3%), and the enlargement of the mediastinal lymph nodes (51.6%) was mostly located in the whole lobe (46%) or upper lobe (25%).IGRA of double lung (54%), and the sensitivity of TST and tuberculosis protein chip to AIDS combined with tuberculosis was 78.3%, 16.7% and 34.7% respectively, and the sensitivity of IGRA was significantly higher than that of T. The sensitivity of ST and tuberculin chip (78.3%vs16.7%, P=0.005, 78.3%vs34.7%, P=0.000).TST and tuberculosis protein chip decreased with the decrease of CD4+T lymphocyte count, but IGRA sensitivity was less affected by CD4+T lymphocyte count. When CD4+T lymphocyte count was 50 /u1, the sensitivity of IGRA was significantly higher than that of tuberculosis protein chip. The positive results of 76.6%vs14.3%, P=0.001, 76.6%vs25.0%, P=0.000).IGRA showed that the latent infection rate of tuberculosis in HIV infected persons was 32.6%, the detection rate of Mycobacterium tuberculosis in AIDS combined with tuberculosis was 20.3%, which was significantly lower than that of 48% (P=0.000).HIV positive patients with HIV negative tuberculosis (P=0.000), and the resistance rate of Mycobacterium tuberculosis was 25%, and HIV negative. There was no significant difference in the 25.2% of the patients with sex. The detection rate of Mycobacterium tuberculosis in the patients with fiberoptic bronchoscopy was significantly higher than that of the AIDS patients with pulmonary tuberculosis (51.2%vs17.7%, P=0.000).HIV positive tuberculosis. The erythrocyte sedimentation rate of HIV infected and HIV negative TB patients was 84 (49-117) mm/h, 53 (20-83) mm/h and 24 (13-41) mm/h, there was a significant difference between the three groups (P=0.000).
Conclusion: the clinical manifestation of AIDS combined with tuberculosis is different. It should be based on the medical history, symptoms and signs, imaging examination, immunological examination, erythrocyte sedimentation and pathogenic examination. Some patients still have to carry out comprehensive measures such as diagnostic treatment to make correct diagnosis of.IGRA, which is less affected by the immune function, and has a greater diagnosis of HIV positive tuberculosis. The detection rate of pathogenic bacteria in.HIV positive TB patients was significantly lower than that of HIV negative tuberculosis. The detection rate of Mycobacterium tuberculosis in lymph node and bronchoalveolar lavage fluid was higher. The multi drug resistance and multi drug resistant strains isolated from AIDS patients were relatively more. The fiberoptic bronchoscopy has a greater diagnosis for the difficult patients. Value. Bronchoalveolar lavage fluid for bacterial culture and TB-DNA detection can improve the detection rate of Mycobacterium tuberculosis.
The study of fourth parts of HIV, TB and HBV/HCV infection
Objective: To investigate the prevalence of HIV, TB and HBV/HCV co-infection and analyze the clinical features of multiple infections, the liver lesion rate and mortality of anti-tuberculosis treatment.
Methods: according to the results of HBsAg and anti -HCV, 361 cases of HIV positive tuberculosis were divided into HIV/TB group, HIV/TB/HBV group and HIV/TB/HCV group, and 1013 cases of HIV negative TB patients were randomly selected as the control group. The subjects were followed up for one year, and compared the type of tuberculosis, the abnormal rate of liver function and the fatality rate of anti tuberculosis treatment.
Results: the infection rate of hepatitis virus in HIV positive group was 32.4%, which was significantly higher than that of 8.9% (P=0.000).HIV positive patients with HIV negative population (21.1% and 26.9% respectively), which were significantly higher than 5.2% and 18.3% (P=0.000 and P=0.001) of HIV negative patients (P=0.000 and P=0.001). Among them, HIV/TB/HBV multicast dispersive tuberculosis was the most 44.4%.HIV positive patients. The drug induced liver damage rate was 4.2%, which was significantly higher than 1% (P=0.000) of HIV negative patients. The drug induced liver damage rate in HIV/TB/HBV group was the highest. The rate of abnormal liver function was 68.4% in the patients with 18.5%.HBV-DNA1.0 x 105copy/ml and 21.1% for HBV-DNA negative or 1 x 105copy/ml patients. The difference was statistically significant (P=0.000).HCV-RNA1. The rate of abnormal liver function was 42.9% in the patients with.0 * 105copy/ml and 10% in HCV-RNA negative or 1 x 105copy/ml patients. The mortality rate was 13.6% in.HIV positive tuberculosis patients (P=0.006), and the mortality rate of 0.9% (P=0.000).HIV/TB/ viral hepatitis group was 19.7%, which was significantly higher than that of HIV negative TB patients. It was significantly higher than 10.7% (P=0.019) in group HIV/TB.
Conclusion: HIV positive tuberculosis patients have higher HBV and / or HCV infection rate.HIV and HBV/HCV combined infection significantly increase the liver damage rate of tuberculosis patients,.HBV and HCV replication level closely related to the anti tuberculosis treatment of liver function damage.HIV, TB and HBV/HCV combined infected people with high mortality rate. Before the anti tuberculosis treatment, the patient was made HIV. HBV and HCV screening can help to detect the mixed infection of the above diseases; cART therapy containing 3TC and TDF schemes for those with HIV, TB and HBV infection, and anti HCV therapy for the HIV, TB and HCV combined infection can help to reduce the rate of liver damage and mortality.
The fifth part is the study of AIDS combined with non tuberculous mycobacterial disease.
Objective: To analyze the prevalence and clinical characteristics of non-tuberculous mycobacteriosis in AIDS patients, and to provide reference for its diagnosis and treatment.
Methods: 19 cases of AIDS combined with non tuberculosis mycobacterium tuberculosis cases in Zhongnan Hospital of Wuhan University were collected and analyzed. The prevalence, clinical manifestations, imaging features, bacterial detection rate and drug resistance were analyzed and compared with AIDS combined with tuberculosis.
Results: the most common symptoms of AIDS combined with non tuberculous Mycobacterium were fever (94.7%), poor (89.5%), fatigue (89.5%), emaciation (84.2%), chest tightness (78.9%), and cough (73.7%). The imaging features were mostly diffuse (88.2%), real change (52.9%), and mediastinal lymph node enlargement (64.7%) more common. AIDS combined with non tuberculosis mycobacterium tuberculosis. The detection rate of bacteria was 21.1%. HIV-positive non-tuberculous Mycobacterium was not sensitive to four first-line anti-tuberculosis drugs (INH, RFP, EMB, Sm) and two second-line anti-tuberculosis drugs (Km, Ofx).
Conclusion: the clinical symptoms of AIDS combined with NTM disease are similar to AIDS combined with tuberculosis. It is easy to cause misdiagnosis and missed diagnosis. There is a difference between NTM's and TB treatment drugs. The definite diagnosis should be based on the medical history, clinical manifestation, bacterial culture and identification of.HIV positive population, the incidence of NTM's disease is significantly higher than that of.HIV positive patients with HIV negative population. NTM is not sensitive to INH, RPF, EMB, Sm, Km and Ofx. The diagnosis, treatment and prevention of AIDS with NTM disease in this area need to be strengthened.
