ABSTRACT
Introduction: Microbiologically confirmed pulmonarytuberculosis patients under Revised National TuberculosisControl Programme (RNTCP) are treated with a 6-monthshort-course chemotherapy (SCC) regimen irrespectiveof co-morbid conditions. The aim of present study was todetermine the time taken for SSC conversion with standardcurrent treatment with anti-tubercular drugs and analysis ofrisk factors if any delaying it. We undertook this prospectivestudy to compare sputum conversion rates (smear) at the endof intensive phase (IP) of Category regimen.Material and methods: was a prospective study which wasconducted for a period of eleven months from August 2018 toJune 2019 at Department of Respiratory Medicine, K.N ChestHospital, S.N Medical College, Jodhpur Rajasthan India.Patients visiting Department of Respiratory medicine and whowere diagnosed as pulmonary tuberculosis by sputum smearexamination were included in study.Result: Sputum smear-positive patients are infectious to closecontacts as well as to community as they continue to expelbacilli for a variable period of time after initiation of DOTSregimen. Most patients undergo sputum conversion by theend of 3rd month. Patients who have predominant cavitatorydisease in radiology, high smear grading before treatment, aprior history of DS/DR tuberculosis are more likely to havedelayed sputum smear conversion.Conclusion: There need to mandate DST at the starting ofDOTS in line with latest RNTCP guidelines to prevent thedevelopment of MDR strains and failures. Also there is astrong need to constitute strong infection control measures tillpatients are labelled as noninfectious.
ABSTRACT
@#Objective To investigate the safety and efficacy of preoperative ultra-short-course chemotherapy combined with surgical treatment of chest wall tuberculosis. Methods The clinical data of 216 patients with chest wall tuberculosis from January 2013 to June 2016 in our hospital were retrospectively analyzed, including 121 males and 95 females with an average age of 35±15 years (range, 4-74 years). Results All patients were treated with anti-tuberculosis drugs for 17.0±11.3 days preoperatively, including 12.5±5.0 days in simple chest wall tuberculosis and 19.4±12.3 days in combined chest wall tuberculosis. The postoperative recurrence rate of chest wall tuberculosis was 3.7%, which was close to or lower than that of routine preoperative antituberculous therapy in patients with ultra-short-course anti-tuberculosis treatment before surgery. Conclusion Preoperative ultra-short-course chemotherapy combined with surgical treatment for chest wall tuberculosis will not increase the recurrence rate of chest wall tuberculosis, and can effectively shorten the hospital stay. Timely adjustment of anti-tuberculosis chemotherapy based on thorough debridement, postoperative drugs, not the preoperative drugs, is the key to reinforce the surgical outcome.
ABSTRACT
Mycobacterium kansasii, most virulent of all atypical mycobacteria, causes pulmonary disease identical to the disease caused by Mycobacterium tuberculosis. Early identification of the species and prompt initiation of treatment for M. kansasii is necessary to prevent morbidity and mortality due to this disease. This case series highlights the similarity in the clinical presentation of both M. tuberculosis and M. kansasii and response to direct observation of short‑course chemotherapy with rifampicin, in the management of pulmonary M. kansasii disease. Larger studies are required to evaluate the long‑term effect of short‑course chemotherapy, especially use of moxifloxacin, in the management of pulmonary M. kansasii disease.
ABSTRACT
Objective: To compare the effectiveness of intermittent with daily chemotherapy (both containing rifampicin) in childhood tuberculosis (age ≤16yrs) in achieving cure/ significant improvement. Design: Systematic Review and Meta-analysis. Methods: MEDLINE and the Cochrane Library were searched for randomized trials of antitubercular regimens containing rifampicin, in children 16 yrs or less with tuberculosis. Two reviewers independently assessed trial eligibility and quality. Data from full articles of selected studies were independently extracted by two authors and analyzed. The odds ratio was obtained for the pooled data in two groups (intermittent and daily therapy). Outcome variables: Cure/significant improvement, relapse rate and adverse events. Results: Four randomized controlled trials comparing twice weekly and daily therapy including 466 children (pulmonary 439; extrapulmonary 27) met the inclusion criteria. Baseline data were comparable. On quality assessment, 3 studies scored 2 and one study scored 3 out of 5 points. Per protocol analysis showed that children receiving intermittent regimen were less likely to be cured than those receiving daily therapy (OR 0.27; 95% CI: 0.14, 0.51). The results of intention to treat analysis suggest similar trend towards lower cure rates with twice weekly regimen (OR 0.66; 95% CI: 0.23-1.84). Conclusion: Twice weekly intermittent short course therapy is less likely to cure tuberculosis in children as compared to daily therapy. There is a need for better quality randomized controlled trials for assessing efficacy of alternate schedule for intermittent therapy for childhood tuberculosis.
ABSTRACT
BACKGROUND: Tuberculous cervical lymphadenitis is one of the common causes of cervical mass in adult (espe cially in woman) in korea. Sometimes it appears to be difficult in defining the role of surgery and duration of antituberculous chemotherapy. METHOD: To clarify the proper duration and/or combination of regimens, we analyzed the clinical data of 31 patient with cervical lymphadenitis diagnosed at Chungnam National University Hospital from March 1996 to December 1996 and all patients were prospectively randomized into two groups(2HREZ/4HRE and 6HREZ) by treatment method. RESULT: Prevalent age, male to female ratio, association with pulmonary tuberculosis and history of previous antituberculous medication were not statiscally different between two groups. The average size of the largest lymph node before teatment was 2.43+/-0.98cm and 3.15+/-1.74cm, respectively and was 0.63cm and 0.6cm after treatment, respectively. In both groups, 2 patients have engrowing node or not changed node during tratment and no recurrence was found during follow up period upto 12 months. In both groups, no significant side reaction resulting in discotinuation or changing the regimens was noticed. CONCLUSION: Short course antituberculosis therapy(2HREZ/4HRE) could be recommanded as effective standard therapy for superficial lymph node tuberculosis. Longterm follow up at least 36 months to observe recurrence might be needed to confirm this conclusion.

BACKGROUND: Short-course chemotherapy for 6 months is well established for pulmonary tuberculosis. However, little is known about the efficacy of the short-course chemotherapy for tuberculous pleural effusion. Tuberculous pleural effusion itself may be self-limiting without any treatment, but about two thirds of the patients with tuberculous pleural effusion may subsequently develop pulmonary tuberculosis within 5 years. After completing treatment for tuberculous pleural effusion, prolonged follow-up is necessary for evaluating the efficacy of the treatment There is still no report on the efficacy of 6-month regimens for tuberculous pleural effusion in Korea, where the incidence of tuberculous disease and drug resistance is high. We studied the efficacy of 6 month short-course chemotherapy comparing with 9 month chemotherapy. METHOD: Retrospective study was done through medical record review in 238 patients with tuberculous pleural effusion who admitted to Asan Medical Center during May 1989-May 1993. The diagnosis of tuberculous pleural effusion was made by bacteriologic or histopathologic study. RESULTS: Among 238 patients, 38 patients were dropped out during follow-up period. In 2 patients, second line drugs were prescribed according to known drug resistance results. And, in 23 patients, treatment longer than 9 months was done due to accompanying extrapulmonary tuberculosis or durg resistance. In 8 patients, treatment regimen was changed due to hepatotoxicity. Remaining 167 cases (70.2%) completed the treatment as scheduled ; 6 month chemotherapy in 88 cases and 9 month chemotherapy in 79 cases. In 60 patients (35.9%) with pleural effusion only in chest X-ray finding, sputum smear or culture for M.tu-berculosis was positive in 6 cases (10.0%), and in 63 patients (37.7%) with radiologically inactive pulmonary tuberculosis, sputum smear or culture was positive in 18 cases (28.6%). In 44 patients (26.3%) with radiologically active pulmonary tuberculosis, the sputum smear or culture was positive in 24 cases (54.5%). In 6-month chemotherapy group (n=88), during mean 23 months (range; 1-61months) follow-up period, pulmonary tuberculosis developed in 1 case (1.4%). In 9-month chemotherapy group(n=79), during mean 23 months (range; 3-70months) follow-up period, pulmonary tuberculosis developed in 2 cases (2.5%). All the cases who developed pulmonary tuberculosis also showed active pulmonary tuberculosis on initial chest X-ray before treatment. CONCLUSION: In patients with tuberculous pleural effusion, the incidence of pulmonary tuberculosis after 6 month chemotherapy showed no difference from that after 9 month chemotherapy. Thus, 6 month short-course chemotherapy seems to be an effective treatment for tuberculous pleural effusion.
