Objective To investigate diagnosis and treatment strategies of patients with pulmonary tuberculosis （TB） complicated by Aspergillus infection. Methods Clinical data of 38 patients with pulmonary TB complicated by Aspergillus infection who underwent surgical treatment from January 2008 to December 2010 in Chengdu Infectious Disease Hospital were retrospectively analyzed. There were 23 male patients and 15 female patients with their average age of 37.8 （23-59） years. Preoperatively，all the patients received regular anti-TB treatment for more than 2 weeks，and patients with definite Aspergillus infection received anti-Aspergillus therapy for more than 3 days with consultation of infectious disease physicians. After above treatment，26 patients underwent lobectomy，1 patient underwent right pneumonectomy，and 11 patients underwent left pneumonectomy. All the patients were followed up at the outpatient department after discharge. They were evaluated every 2 weeks in the first 3 months，every 1 month after 3 months，and every 6 months after 1 year. During follow-up，they received acid-fast bacillus smear and sputum culture to check Aspergillus，as well as CT chest scan. Results All the patients successfully received surgical resection of the pulmonary lesion without perioperative death or severe complication. Postoperative pathology examination confirmed pulmonary TB with Aspergillosis infection in all the 38 patients，whose basic diseases included TB cavity in 17 patients，TB-destroyed lung in 12 patients，and post-TB bronchiectasis in 9 patients. All the patients were followed up after discharge for 1.5-4.5 years. During follow-up，they received regular anti-TB therapy for adequate duration in addition to antifungal medications such as voriconazole. None of the 38 patients had recurrence of Aspergillus infection or pulmonary TB. One patient had hemoptysis which was controlled after proper treatment during follow-up. Conclusion Missed diagnosis rate of pulmonary TB complicated by Aspergillus infection is high. Surgical resection of the pulmonary lesion and postoperative medication treatment are the most effective treatment strategies for patients with pulmonary TB complicated by Aspergillus infection.
The paper extended the previous model by adding the effect of the permanent resident on the migrants. The numerical simulation indicated that the basic reproductive numbers should be less than one in permanent residents and migrants in order to eliminate disease from the population. Evaluation on the TB-Screen Strategy of Canada showed that the epidemic of TB was sensitive to the TB control strategies.
Objective To estimate the proportion of Chongqing TB patients who have access to mobile phones, to describe the utilization practice of those mobile phones, and to learn the general information of those TB patients, so as to provide feasibility basis for further intervention of SMS reminder systems. Methods The stratified cluster sampling method was used and four TB high-risk districts were selected. Both quantitative and qualitative research methods were used to interview the TB patients and suspects who had come to their local TB dispensaries during the past two months. The quantitative data was double entered using EpiData 3.1. The association of mobile phone utilization parameters with key variables was determined using chi-square test and logistic regression analyses. The qualitative data was managed, coded and retrieved using MAXQDA, and analyzed using thematic framework approach. Results Of the patients interviewed by quantitative research, the mobile phone ownership rate was 91.1%; 914 cases (80.4%) of the respondents were able to receive text messages; and most people (81%) held favorable opinions on SMS reminders. The main factors related to mobile phone ownerships and receiving SMS were age, occupation, education level, and place of residence. The male patients, in the age group of 19-49 years old, with education level of high school or higher were more likely to have access to mobile phones. The results from qualitative interview were similar. Conclusion Considering the high access to mobile phones of patients interviewed and patients’ views on SMS reminders, it is feasible to conduct a pilot intervention using SMS as a strategy to improve adherence to TB treatment in Chongqing.
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 We investigated and analyzed past and ongoing welfare programs related to health equity, and the relevant policies, documents, and interventions measures for improving China’s migrant worker population’s accessibility and utilization of tuberculosis (TB) control services in TB control programs. Then we evaluated their impactin order to provide evidence and suggestions for the further TB prevention and treatment. Methods We retrieved published documents about TB prevention and treatment of the migrant worker population dating from 1998 to 2008 from MEDLINE, PubMed, CNKI, CBMdisc CDDB, and VIP electronically. Simultaneously, a series of interviews was conducted with patients who used the programs. Results Totally, 58 documents were retrieved. Of these documents 13 passed eligibility criteria: eight have been published, five have not been published, and only one of them is RCT with B degree for quality of evidence. Secondary document research has suggested that the intervention measures that have been adopted concerning TB in China, including health promotion, providing incentive, patient tracking and supervision management. Although tuberculosis cure rates have improved, the scene interviews show that the majority of TB and suspected cases of patients don’t have enough knowledge on TB prevention and free treatment policies. It is often difficult to track the migrant population. TB detection and treatment still need to be enhanced. Conclusions There it is lack of high-quality documents about good intervention design, so it is difficult to make a objective and fair evaluation to the effects of intervention on the migrant population. In the future, we should carry out large-scale, multicenter, high-quality RCTs specifically for TB controlin the migrant population in order to provide evidencefor making a scientific and feasible intervention project.
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.
