OBJECTIVETo introduce co-word analysis into the analysis of the current research status of childhood tuberculous meningitis, to compare the similarities and differences in research topics of the field in China and abroad over the past decade, and to discover the advantages and weak links in the study field in China.
METHODSPubMed, CNKI, VIP, and Wanfang Data were searched for the articles which met the inclusion criteria. Ucinet 6.0 and Netdraw were used for co-occurrence analysis, and the co-article relationship between high-frequency key words was visualized.
RESULTSA total of 226 articles abroad and 186 Chinese articles on childhood tuberculous meningitis were obtained. The figures for co-occurrence analysis of high-frequency key words in research articles on childhood tuberculous meningitis in China and abroad were successfully plotted. Compared with the studies in China, the studies abroad were more sophisticated and well-developed, with more studies on drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis. The key words listed in the studies abroad were more standard. The studies in China on childhood tuberculous meningitis concentrated on vaccination and nursing.
CONCLUSIONSIn general, the studies on childhood tuberculous meningitis in China and abroad have the same directions. The studies abroad have a complicated network and use more standard key words. The studies on childhood tuberculous meningitis are well conducted in China. However, more studies are needed for drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis in future.

2.Chemotherapy of tuberculosis and its challenges.
Acta Academiae Medicinae Sinicae 2009;31(4):389-392
Tuberculosis (TB), a chronic communicable disease, continues to be a global public health concern. Slow decline of TB incidence and prevalence, human immunodeficiency virus/TB coinfection, growth of multidrug-resistant/extensively-resistant TB have made the control of TB even more challenging. Chemotherapy of TB has developed for decades and now also faces similar challenges.

The global emergence of multidrugresistant (MDR) tuberculosis (TB) and extensively drug-resistant (XDR)-TB threatens to derail the efforts of TB control programmes worldwide. From 2000 to 2010, 161 pulmonary MDR-TB cases (including six XDR-TB cases) were reported in Singapore, and of these, 80% occurred among the foreign-born, with an increasing trend seen after 2004. Among new pulmonary TB cases, the highest incidence of MDR-TB occurred among patients from Myanmar (8%), followed by Vietnam (4.4%) and China (2.3%), while among those previously treated, the highest incidence was found in patients from Vietnam (50%), followed by Indonesia (33%) and Bangladesh (33%). Although the proportion of Singapore-born pulmonary TB cases with MDR-TB has remained comparatively low (0.2% and 1.3% in new and previously treated cases, respectively), there is no room for complacency. Top priority must be accorded toward the proper treatment of drug-susceptible TB cases under strict programme conditions so as to prevent the development of MDR-TB in the first place.

Objective: To compare the characteristics of children's pulmonary tuberculosis (PTB) cases reported from 2019 to 2021 before and during the implementation of the Action Plan to Stop Tuberculosis. Methods: Based on the reported incidence data and population data of child pulmonary tuberculosis (PTB) notified to the Chinese Center for Disease Control and Prevention (CDC) Tuberculosis Information Management System (TBIMS) from 2019 to 2021, the population information and clinically relevant information in different years were compared. Results: From 2019 to 2021, the reported cases of PTB in children were 363, 664 and 655, respectively. The number of reported cases increased significantly. The median age of the cases in children increased from 10.4 years in 2019 to 11.7 years in 2021 (P=0.005) over a three-year period. The etiological positive rate increased significantly from 11.6% (42/363) in 2019 to 32.2% (211/655) in 2021 (P<0.001). The positive rate of molecular testing increased most significantly, which became the main means of etiological detection and accounted for 16.7% (7/42), 62.0% (57/92) and 75.4% (159/211) of the children with positive etiological results, respectively. The resistance rates of isoniazid and rifampicin were analyzed in children with PTB who underwent drug sensitivity tests. The results showed that the resistance rates of isoniazid and/or rifampicin were 2/9, 3.9% (2/51) and 6.7% (11/163), respectively, with an average of 6.7% (15/223) over three years. The median patients' delay was 27 (12, 49) days in 2019. It was reduced to 19 (10, 37) days in 2020 and 15 (7, 34) days in 2021, both significantly lower than 2019 (P=0.009 and 0.000 2, respectively). Conclusion: From 2019 to 2021, the reported numbers of children with PTB and children with positive etiological results increase significantly in Liangshan Prefecture, while the diagnosis delay of patients significantly reduces.

We assessed the role of diabetes mellitus (DM) on treatment effects in drug-susceptible initial pulmonary tuberculosis (PTB) patients. A prospective study was conducted in eight provinces of China from October 2008 to December 2010. We enrolled 1,313 confirmed drug-susceptible initial PTB patients, and all subjects received the treatment regimen (2H3R3E3Z3/4H3R3) as recommended by the national guidelines. Of the 1,313 PTB patients, 157 (11.9%) had DM; these patients had more sputum smear-positive rates at the end of the second month [adjusted odds ratios (aOR) 2.829, 95% confidence intervals (CI) 1.783-4.490], and higher treatment failure (aOR 2.120, 95% CI 1.565-3.477) and death rates (aOR 1.536, 95% CI 1.011-2.628). DM was a contributing factor for culture-positive rates at the end of the second month and treatment failure and death of PTB patients, thus playing an unfavorable role in treatment effects of PTB.

OBJECTIVES: To estimate the resistance rate and to correlate the clinical characteristics of resistant tuberculosis with the patients of pulmonary tuberculosis who were referred to the university hospital. METHODS: We prospectively performed sensitivity tests for all patients who were diagnosed as active tuberculosis by sputum smear or sputum culture from January, 1995 to June, 1996. Patients profile, previous treatment history, patterns of drug resistance, initial chest films and other clinical findings were analysed. RESULTS: Overall, 24(26.0%) of the 92 patients had resistance to at least one drug and 8(8.6%) had resistance to isoniazid(INH) and rifampin(RFP). Among the 66 patients without previous tuberculosis therapy, 11(16.6%) were drug-resistant and 2(3.0%) were multi-drug resistant. Among the 26 patients with previous therapy, 13(50.0%) were drug-resistant and 6(23.0%) were multi-drug resistant. For all 92, resistance to INH was most common (19.5%), followed by RFP (9.7%) and ethambutol (9.7%). Drug resistance was significantly high in previously treated patients and in cavity-positive patients. Treatment failure was also high in previously treated patients with resistant tuberculosis. In patients with primary resistance, treatment failure was not observed. CONCLUSION: Sensitivity tests are strongly recommended in all culture positive patients with previous therapy but, in patients with primary resistance, sensitivity tests are not required. Proper combination chemotherapy should be given under careful surveillance.

Tuberculosis is still one of the most serious infectious diseases in Korea. Tuberculosis in childhood is a serious prablem to Korean pediatricians. Miliary tuberculosis, a form of extrapulmonary tubercubsis, has been frequently observed in outpatient dispensaries or in-patient wards in Korea. Only one clinical review by Mm et al (1969) was reported. We have summarized another eighty four psdiatric patients who were observed during a nine years and three months period from Jan. 1960 to March of 1969, at Wonju Union Christian Hospital, Wonju, Kang Won Do, a branch hospital of our Saverance. The following results were obtained; 1). During nine years and three months from Jan. 1960 to March of 1969, eighty four cases of miliary tuberculosis were observed which was 1.7 per cent of the total admission of pediatric patients (4,991) during the above period. 2). The youngest one was a five month old female infant and the oldest was a thirteen year old boy. The age group of three to six years included 40.5 per cent while 10.7 per cent were under one year. 3). Only eighteen per cent of the patients had a definite contact history with tuberculosis in the family. 4). Their chief complaints on admission were fever, cough, vomiting, loss of appetite, abdominal pain, fatigue, in order. All eight convulsive patients had complication of meningitis. 5). Negative tuberculin responses were found in more than fifty per cent of patients. 6). Tuberculous meningitis was the most frequent complication (28.5 per cent)in miliary tuberculosis. Tuberculous complications were found in fifty per cent of all patients. 7). Death rate was twelve per cent. Six out of ten deaths occurred within three days after admission. Eight out of ten deaths were complicated cases of tuberculous meningitis. Seven out of ten deaths were male patients. 8). In improved cases, improvement on X-ray and by clinical symptoms appeared after two weeks or several months. 9). The Patients were treated by triple chemotherapy and addition of corticosteroid, but we did not find a remarkable effect of steroid. 10). The prevention must precede treatment and doctor's and patient's attention to miliary tuberculosis must be emphasized.

BACKGROUND/AIMS: We evaluated the trend in the rates of drug-resistant tuberculosis (TB) over time, as well as the difference in the drug-resistance pattern between pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) at a private referral center in South Korea. METHODS: All patients with culture-confirmed TB from 2006 to 2013 were included. RESULTS: In total, 1,745 patients were included: 1,431 (82.0%) were new cases, and 314 (18.0%) were cases treated previously; 1,610 (92.3%) were diagnosed with PTB, and 135 (7.7%) were diagnosed with EPTB. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB were detected in 5.8% and 2.0% of new cases and in 20.1% and 8.6% of previously treated cases, respectively. The MDR TB rate during the study period decreased remarkably, whereas the MDR and XDR TB rates decreased significantly in previously treated cases. No difference in the drug-resistance rate was detected between PTB and EPTB. CONCLUSIONS: The TB drug-resistance rate, particularly that of MDR TB, remained high at a private referral hospital, and the drug-resistance rate did not decrease significantly from 2006 to 2013. This finding underscores the need for a national survey regarding the prevalence of drug-resistant TB to obtain the most accurate and current drug-resistance status in South Korea, including the private sector.
