2010 年世界卫生组织( WHO) 年度报告指出, 中国2009 年有110 万至150 万名结核患者, 并且每 10 万人口中即有新增病例50 至99 人。报告中也提到, 近年吸毒人数增多, 世界范围内有11% ～ 13% 的结核患者呈HIV 阳性。而在中国, 虽然仅有 1. 5% 的新增结核患者显示HIV 阳性, 比2007 年的 1. 9% 略有下降, 但中国结核病群体巨大, 其形势仍不容忽视[ 1, 2 ] 。
Objective To evaluate the diagnosis value of purified protein derivative (PPD) antibody tests in childhood tuberculosis. Methods We reviewed 126 cases of hospitalization children tested body fluid PPD antibody by Enzyme-Linked Immunosorbent Assay (ELISA). Twenty-two them were diagnosed with tuberculosis. We determined the sensitivity, specificity, diagnostic likelihood ratio, positive prognostic value, negative prognostic value, post-test probability, respectively. Results The following accuracy statistics for the PPD body liquid antibody tests in this study: sensitivity, 45.45%; specificity, 91.35%; diagnostic likelihood ratio positive, 5.25; diagnostic likelihood ratio negative, 0.597; positive predictive value, 52.63%; negative predictive value, 88.79% and post-test probability, 48.09% in 15% of prevalence. Conclusion This study shows that body fluid PPD tests have limited value for diagnosis of tuberculosis in pediatric tuberculosis. Clinic physicians should be wary of the positive results of body fluid PPD antibody tests. The value of diagnosis is related to prevalence of tuberculosis in the specific hospital.
Objective To investigate and analyze the past and on-going pro-poor programs related to health equity, and the relevant policies, documents, interventions measures, etc. to improve the China prisoners’ accessibility and utilization of tuberculosis (TB) control services in TB control programs, then evaluate their impacts and influences to provide evidences and suggestions for the further work of TB prevention and treatment. Methods Retrieve published documents about TB prevention and treatment of transient population dating from 1998 to 2008 from MEDLINE, PubMed, CNKI, CBMdisc CDDB and VIP with computers. Simultaneously, a series of interviews was conducted after we got the agreement of the interview people by using non-probability statistics methods. Results A total of 23 documents were retrieved, and they were consonant with the criteria, among which 8 were published and 5 were policy documents. The study on the second document showed the measures that presently applied on TB patients among prisoners in China: find patients through surveys, inspect every prisons and patients going to visit doctors with symptoms; concerning differences between various groups of prisoners, the measure of “classify and instruction, enroll together and treat” was applied; carry out health education in the prisons and so on. After the implement of various measures, the knowledge awareness, discovery rate, accomplishment ratio, cure rate and so on were all improved. The results of the qualitative interviews showed: the TB patients and the doubts among prisoners could be well gotten together and isolated to receive DOTS; doctors were able to receive trainings on TB treatment and take appointment with certificate. Conclusion According to the results of qualitative interviews, the published and the secondary documents, it could be seen that DOTS are well implemented with remarkable effects.

Objective To study the efficacy and safety of combined anti-tuberculosis regimen containing bedaquiline in the treatment of multidrug-resistant tuberculosis (MDR-TB). Methods A total of 69 MDR-TB patients treated by joint regimen combined bedaquiline with other anti-tuberculosis drugs between March 2018 and August 2019 in Public Health Clinical Center of Chengdu were taken as the trial group, and 60 MDR-TB patients received treatment without bedaquiline between June 2016 and December 2017 in the same hospital were taken as the control group. The efficacy and safety of the two groups were compared. Results The 69 patients in the trial group included 44 males and 25 females, aged from 21 to 63 years, with an average of (34.6±11.0) years; 58 patients (84.1%) completed the 24-week treatment with bedaquiline, while 11 patients did not complete the treatment, including 3 deaths (4.3%), 1 loss of follow-up (1.4%), 1 withdrawal from the study (1.4%), and 6 discontinuation due to adverse events (8.7%). Among the 54 patients with positive results of tuberculosis on baseline sputum culture, 49 transformed to negative results within 24 weeks of treatment (the negative conversion rate was 90.7%), and the median negative conversion time was 13.0 weeks. The 60 patients in the control group included 45 males and 15 females, aged from 16 to 66 years, with an average of (35.5±13.2) years. Among the 53 patients with positive results of tuberculosis on baseline sputum culture, 30 transformed to negative results within 24 weeks of treatment (the negative conversion rate was 56.6%), and the median negative conversion time was 12.0 weeks. The negative conversion rate of sputum bacteria in the trial group was significantly higher than that in the control group (χ2=16.133, P<0.001). The most common adverse reactions in the trial group were liver function abnormalities (42 cases, 60.9%), prolonged QTc interval (37 cases, 53.6%), electrolyte disturbances (20 cases, 29.0%), and blood system damage (20 cases, 29.0%). In the 37 patients who experienced prolonged QTc interval, there were 8 patients with QTc intervals≥500 ms and 29 patients with QTc intervals ≥450 ms and <500 ms, with a median occurrence time of 16.0 weeks, among whom 25 patients experienced prolonged QTc interval in 4-48 weeks after the withdrawal of bedaquiline. Conclusion The negative conversion rate of tuberculosis sputum culture of patients with MDR-TB treated by bedaquiline combined with other anti- tuberculosis drugs is high, but electrocardiogram should be closely monitored during and after the treatment in order to guard against the potential cardiac toxic effects of bedaquiline.
ObjectiveTo discuss clinical characteristics and nursing countermeasure of pregnant/delivery women with tuberculosis. MethodsFrom January 2012 to December 2013, 52 cases of pregnant women complicated with tuberculosis were included. We offered specific nursing according to the psychological counseling, reasonable administration, diet nursing, fever and prevention of hospital infection on the base of their clinical features, and then analyzed the effect. ResultsIn 52 patients who had undergone the tuberculosis and obsterrics and gynecology treatment, 4 puerperal patients died of severe pneumonia and multiple organ failure; in 48 gestational patients with tuberculosis, 23 early-middle term patients accept termination of pregnancy, and in 25 middle-late term patients, 3 had full-term natural labor, 4 underwent full-term cesarean section, 5 had premature labor, and 13 continued the pregnacy. Sixteen neonatus (including 4 given at the other hospitals) had normal results of physical examination without any deformity, in whom 5 had low body weight (body weight less than 2500 g), with negative results of tuberculin test and the result of 3-moth follow-up was normal. Three months after the anti-tuberculosis treatment, the lesion was obviously absorbed in 25 patients and in 23 patients within half of a year. No patients had hospital infection. ConclusionNursing care of pregnant patients with tuberculosis should strengthen the guidance on the patients health education, improve their compliance and self-protection knowledge. Also should strengthen the basic level medical personnel training and improve the ability of early diagnosis of tuberculosis and early treatment to reduce maternal mortality.
Objective To explore the relationships between the polymorphisms of inhibitor genes WIF1 and DKK1 in WNT signaling pathway and susceptibility to tuberculosis, clinical characteristics and laboratory indexes. Methods From December 2014 to November 2016, 475 tuberculosis patients and 370 healthy controls of West China Hospital of Sichuan University were enrolled in the study, and the clinical data of the subjects were collected. High-throughput genotyping technique was used to detect the polymorphisms of WIF1 rs58635985 and DKK1 rs11001548 in WNT signaling pathway. The allele frequency distribution, genotype, genetic model, clinical features and laboratory indexes of two single nucleotide polymorphisms were analyzed by χ2 test and logistic regression analysis. Results There was no significant difference in the allele frequency distribution (P=0.275, 0.949), genotype (P=0.214, 0.659) or genetic models: additive model (P=0.214, 0.659), dominant model (P=0.414, 0.827), recessive model (P=0.227, 0.658) of rs58635985 and rs11001548 between the tuberculosis group and the healthy control group. Subgroup analysis showed no significant difference in allele and genotype distribution between rs58635985 and rs11001548 (pulmonary tuberculosis group vs. healthy control group: P>0.05; pulmonary tuberculosis groupvs. extra-pulmonary tuberculosis group: P>0.05). There was no significant difference in the clinical features (fever, night sweat, fatigue,etc.) or laboratory indexes (complete blood count, erythrocyte sedimentation rate, TB-DNA, etc.) (P>0.05). Conclusions There is no association between rs58635985 of WIF1 gene or rs11001548 of DKK1 gene and genetic susceptibility, clinical characteristics and laboratory indexes in Han population in Western China. To expand the sample size for verification and analysis in different populations is necessary.
ObjectiveTo evaluate the diagnostic value of T-SPOT.TB assay in patients with hematological disorders and tuberculosis. MethodsA total of 82 patients with hematological disorders and suspected tuberculosis diagnosed between March 2012 and April 2013 received T-SPOT. TB assay in the peripheral blood mononuclear cells. ResultsThe positive detection rate of T-SPOT.TB assay for patients with hematological disorders and tuberculosis was 59.09% (13/22), which was higher than the positive detection rate of anti-TB antibody test[13.64% (3/22)]. The sensibility and specificity of T-SPOT.TB assay for patients with hematological disorders and tuberculosis was 59.09% (13/22) and 68.33% (41/60), respectively. ConclusionT-SPOT.TB assay is of great value on diagnosis of tuberculosis for patients with hematological disorders and suspected tuberculosis. The diagnostic value of T-SPOT.TB assay is more important for tuberculosis infected patients; it can be used as an accessorial diagnostic method for patients with hematological disorder and suspected tuberculosis.
Tuberculosis is one of the major infectious diseases that seriously endanger human health. Since 2014, it has surpassed human immunodeficiency virus/acquired immunodeficiency syndrome as the first infectious disease in patients with single pathogens. China is the third-largest country in the world in terms of high burden of tuberculosis. In 2016, there were about 900 000 new cases of tuberculosis in China. China is facing a severe tuberculosis epidemic, especially for the early diagnosis of tuberculosis and misdiagnosis of tuberculosis, which leads to delay in treatment and the spread of tuberculosis. With the application of artificial intelligence in the medical field, machine learning and deep learning methods have shown important value in the diagnosis of tuberculosis. This article will explain the application status and future development of machine learning and deep learning in the diagnosis of tuberculosis.
