Schistosomiasis is a parasitic disease caused by trematodes (body flukes), affecting millions worldwide. However, its pulmonary manifestations are rare. We report a rare case of a 51-year-old People Living with HIV male, managed in a tertiary care hospital in west India in May 2023, vegetable vendor who was admitted with complaints of dysphagia, odynophagia, fever and chest pain for 3 days, cough and breathlessness for 1 month. Chest x-ray and CT scan were suggestive of hypodense fluid collection with rim enhancement along right lateral and posterior aspect of thoracic esophagus. All routine investigations and urine cultures were sent, which turned to be inconclusive. Upper Gastrointestinal scopy was suggestive of pangastritis. Fiberoptic bronchoscopy was done with no structural abnormality or endobronchial mass. Bronchoalveolar lavage from right lower lobe was sent for CBNAAT, Gram and Ziehl Nelson staining and cultures, acid fast bacilli cultures and cytology which revealed parasitic infection with Schistosoma haematobium. The patient was treated with tablet praziquantel P/O 2400 mg in divided doses for 1 day followed up after two weeks when he experienced reduced symptoms. Sputum examination was repeated showed Schistosoma on wet mount and hence a repeat dose of tablet praziquantel 3000 mg in divided doses was given and was advised to follow up 2 weeks later, which showed resolution of right lower zone opacities.

INTRODUCTION- Tuberculosis (TB) is a chronic granulomatous infection principally caused by Mycobacterium TB and less frequently by ingestion of Mycobacterium bovis infected unpasteurized cow’s milk or by other atypical mycobacteria. It presents a great social and economic problem and is one of the major factors responsible for the high morbidity and mortality in India. The incidence of tuberculous cervical lymphadenopathy now accounts for two third of the extra pulmonary tuberculous lymphadenopathy. Most of these are supposed to be tuberculous in origin because of greater incidence of pulmonary tuberculosis in our country. At the same time there are other causes of lymph-adenopathy which are usually misdiagnosed as tuberculosis. It has been a common problem for both to clinicians as well as pathologist from to diagnose tuberculosis. Methos and materials- The present work is carried out in 100 clinically suspected cases of tuberculous cervical lymphadenitis attending E.N.T., Surgery, Paediatrics and Medicine Department of central India institute as an outdoor/indoor patient during the period of one year. Patients with enlarged cervical lymph nodes with a history suggestive of tuberculosis were included after taking an informed consent. Results- Study was done on 100 clinically suspected cases of tuberculous cervical lymphadenitis, Tuberculosis was diagnosed in 57% cases by FNAC, smear and culture together, the maximum incidence of tuberculosis was observed in second and third decades, Females were more affected (64%) than males with the ratio of 1:2.3. By FNAC 42% accuracy was obtained, 30% cases were AFB smear positive in our study this rate of incidence is nearer to other authors. In our culture study, 57 cases were diagnosed as tuberculous and 4 cases as non-tuberculous cervical lymphadenitis. Culture positive was higher in granulomatous necrotic lesions. Sensitivity, specificity and predictive values of culture study were significantly higher than FNAC and smear. These methods of investigation need considerable experience and confidence of a pathologist who perform the procedure for a better result. When culture was taken as Gold Standard, cytology was found to be more sensitive than smear. Conclusions – from this study we concluded that Both FNAC and smear are quick, simple, less traumatic and cost-effective methods and used as a routine investigating procedure in OPD of urban and semi-urban hospitals. Simplicity of these techniques (FNAC & Smear) combined with early availability of results and good diagnostic accuracy warrants their clinical application. Missed cytological diagnosis and isolation of non-tuberculous mycobacteria justify culture studies on all suspected tuberculous lymphadenitis cases. [ABSTRACT FROM AUTHOR]

Background: In 2021, one third of the notified TB patients in the country were contributed by the private sector. But evidence supports nearly 50% of TB patients first seek care from a private practitioner (PP). Aims/objectives: The study was carried out to understand the TB care practices among the private practitioners based on Standards of TB Care in India (STCI) in Davangere city. Methodology: Cross-sectional study was conducted among the 365 qualified, registered private practitioners of Davangere city who have treated at least one presumptive TB case in the past year. Study was conducted from Jan 2017 to June 2018 Results: PPs considered weight loss (80.5%) and hemoptysis (70.1%), followed by cough and fever as a major symptom to screen for TB. 87.4% of them used Chest Xray as diagnostic tool, followed by Mantoux test and Sputum smear examination 83% of TB cases diagnosed were notified but the public health actions like contact tracing, preventive measures among the household contacts were compromised. Conclusion: This study identifies the need to sensitize PPs about the services available in the government sector and the updates in the TB program, which could help in meaningful partnership towards efforts of TB elimination in the country.

Background: India, like many other developing nations has seen a steady decline in pulmonary tuberculosis over the past decades due to successful implementation of RNTCP-DOTS programme nationwide and improvement in social & economic condition of the general population. It is now seen that extra-pulmonary presentations form a major proportion of new cases. A majority of them present as head and neck tuberculosis (TB) - tubercular cervical lymphadenopathy. In spite of advent of newer diagnostic tools like nuclear ploidy, genetic analysis, nuclear scan and so on, Ultrasonography (USG) being the simplest, quickest and noninvasive diagnostic modality with high sensitivity has gained a very significant place in clenching early diagnosis of neck nodes. Aims & Objectives To calculate the Sensitivity, Specificity & Predictive Accuracy of USG in diagnosis of Extra Pulmonary Tuberculosis (EPTB) when presenting as cervical lymphadenopathy. Material &Methods A prospective, cross sectional study was conducted for 12 months in a Medical College and Hospital among the patients attending the ENT, Surgery, Paediatrics and Medicine OPD & IPD with cervical lymphadenopathy. After estimating the sample size,172 patients were included in this study. After obtaining approval from the IEC and informed consent of the participants, they were selected according to the inclusion and exclusion criteria. Result The Sensitivity and Specificity of USG in reference to TB cervical lymphadenopathy were 91.43% and 84.38% respectively with a positive predictive value of 96.24% and negative predictive value of 69.23%. 15.63% were false positive and false negative were 08.57%. Conclusion USG is an effective, noninvasive, inexpensive and safe tool with a high Sensitivity which can become an important and integral screening modality in the diagnosis of Extra Pulmonary Tuberculosis.

Background: India has a high prevalence of tuberculosis and latent tuberculosis infection (LTBI) is common in the general population. LTBI can progress to active tuberculosis in almost 10% patients and the risk increases with immunosuppression. This predisposes patients of psoriasis on systemic therapy for the development of active tuberculosis. Aims: To find the prevalence of LTBI in patients with psoriasis planned for systemic therapy. Methodology: It was a prospective observational study conducted in a tertiary care center during period Jan‑Dec 2019. Patients older than 18 years with chronic plaque psoriasis planned for systemic therapy and willing to be part of the study were included. Baseline clinical data were collected. Radiograph of chest and tuberculin skin test (TST) was performed in all patients. Detailed evaluation including sputum examination and computed tomography of the chest and abdomen were performed in patients with TST >10 mm. Results: A total of 105 patients met the inclusion criteria of the study, with the mean age of patients being 29.5 ± 2.12 years. Out of these patients, 58 were males and 47 females. The mean duration of psoriasis was 2.95 ± 1.3 years. The mean PASI score was 16.71 ± 4.384. Mantoux was positive (>10 mm) in 33 (31.42%) patients. Two patients were found to have features of active tuberculosis based on imaging and microbiological investigations. Totally, 31 (29.5%) patients had LTBI and were treated with isoniazid and rifampicin for three months while 2 (1.9%) patients were treated with four drugs antitubercular regimen. Limitations: Small sample size, convenience method of sampling and study population limited to those visiting medical college hospital are its major limitations. Conclusion: LTBI is common in study population and screening for LTBI should be performed in all patients of psoriasis planned for systemic therapy. A thorough search for active tuberculosis should be performed. Timely detection of LTBI helps in the prevention of development of active tuberculosis in the patients on immunosuppressive treatment.

Tuberculosis is a major cause of morbidity and mortality throughout the world. Major population of patients suffering from Tuberculosis belong to such areas of the community where the traditional tests of Tuberculosis are not practical to set up because of the extensive infrastructural requirements like continuous power supply. TrueNat is a new testing facility that uses a portable battery-operated device that tests the presence of the tubercle bacilli in the sputum as well as test the Rifampicin resistance of the bacillus in about an hour's time, by the use of rapid molecular diagnostics. WHO endorsed this test for the initial testing of Tuberculosis and ICMR allowed the use of TrueNat for COVID-19 testing. Contagious diseases can impose a serious health hazard to dental staff due to the aerosolizing procedures being carried out in dental office. TrueNat testing before such procedures can help in significant risk reduction and quicker results which will help in avoiding delay in dental treatment. Due to higher accuracy, reliability, same day testing and reporting by TrueNat, it can play a pivotal role in the future of diagnostic abilities of infectious diseases. [ABSTRACT FROM AUTHOR]

In India, an estimated 50% of tuberculosis (TB) patients are diagnosed and managed by private providers (PPs). However, there is limited information on treatment outcomes among those treated by PPs largely because of a lack of systems for patient follow-up and documentation of the outcomes. Tuberculosis Health Action Learning Initiative (THALI) project implemented in six districts of West Bengal, supported PPs in managing TB patients and systematically documented the TB treatment outcomes of such patients. This provided us an opportunity to describe the treatment outcomes and assess factors associated with 'unsuccessful outcomes' among TB patients notified by PPs from January to April 2018. This was a retrospective cohort study using routinely collected data. During the study reference period, 2347 patients were notified from 389 PPs. The patient's mean (SD) age was 39.9 (17.2) years and 61% were males. Of the total, about 86% had pulmonary TB, 95% were new cases, and 23% were microbiologically confirmed (either on sputum smear microscopy or Xpert assay). Among 2347 patients, 19% received free drugs from the National Tuberculosis Program (NTP) under the supervision of PPs while the rest purchased anti-TB drugs from the private pharmacies. The 'successful outcomes' (cured and treatment completed) were seen in 86.1% (95% confidence interval (CI), 84.6%-87.4%) patients and 8.6% were 'not evaluated'. The patients who received free NTP drugs (adjusted relative risk-4.0 (95% CI: 3.1-5.0)) had a higher risk of 'unsuccessful outcomes' than those who availed of drugs from private pharmacies. The high 'successful outcomes' among TB patients treated by PPs are promising. However, higher 'unsuccessful outcomes' among patients on free NTP drugs need to be explored, and suitable corrective actions have to be taken. [ABSTRACT FROM AUTHOR]

Background: Tuberculosis is the major problem of public health with high morbidity and mortality, a continuing scourge of India. The DOTS strategy of the national program targeted on identifying and treating smear +ve cases, which focus on infectious cases and preventing the transmission. Thus the children are ignored as a hidden epidemic since smear-positive cases are focused on diagnosis which is much less in children when compared to adults, thus the prevalence and morbidity of disease in children is not available mainly from developed countries. Aim and objective: To study the clinical profile of childhood tuberculosis, to compare the efficacy of CBNAAT as a diagnosis tool between pulmonary and extrapulmonary TB. Materials and methods: In the prospective study, in the Department of Pediatrics and Chest Medicine in our tertiary care hospital, Salem in the year 2018 January to December. Informed consent was obtained from parents and caregivers before including the children in the study. There was no risk to the children due to the study. A data collection sheet (proforma) was filled for each child based on the inclusion criteria that were suspected presumptive TB after obtaining informed consent. Results: Among 100 samples collected, 69 children had extrapulmonary symptoms and signs; when compared to 31 had pulmonary symptoms and signs. Among 31 presumptive TB cases, the gold standard microbiologically confirmed TB was 2 as compared to 6 cases which were detected by CBNAAT results that were not detected by sputum examination. This was found to be statistically significant (P=0.017). Thus CBNAAT increases the detection rate of pulmonary TB thrice. Thus Sensitivity of the CBNAAT was 94%, Specificity was 86.67, PPV 33.33, NPV 95.12; Accuracy 73.33. This was highly significant at p<0.1. Among 100 presumptive TB cases, CBNAAT was positive in 10, it also detects cases that were negative by conventional laboratory methods. Conclusion: When compared to the efficacy of CBNAAT with gold standard microbiological confirmation, CBNAAT detects thrice the caseload in pulmonary TB in the community. Thereby increasing the case detection rate and preventing the complication. In the case of extrapulmonary TB, CBNAAT detects 30% of pathologically confirmed TB lymphadenitis and 33% CNS TB among pediatric TB. [ABSTRACT FROM AUTHOR]

Background: Neurotuberculosis is among the most severe type of tuberculosis with high mortality and morbidity in all age groups. Various sociodemographic and disease-/treatment-related factors have emerged over the years that can affect clinical and radiologic features of neurotuberculosis. Objective: To investigate various clinical and neuroradiologic presentations of neurotuberculosis. Methodology: This cross-sectional study was done in a tertiary care center of northern India. The patients between the ages of 3 months and 18 years with newly diagnosed neurotuberculosis were enrolled after taking informed consent. Results: A total of 78 patients (37% males) were enrolled. Fifty-six patients (72%) had tubercular meningitis (TBM) and 22 (28%) isolated tuberculomas. Very high percentage of patients in both the groups was BCG vaccinated. In the tubercular meningitis group, fever (68%), headache (59%), and vomiting (54%) were the most common complaints whereas in the tuberculoma group, seizures (95.5%) were the main complaint and systemic symptoms were rare. In tubercular meningitis patients, cerebrospinal fluid–based studies showed cartridge-based nucleic acid amplification test (Xpert MTB/RIF) positivity for Mycobacterium tuberculosis in 17.6% cases, whereas on gastric aspirate and sputum examination, acid-fast bacilli were seen in 30.7% and cartridge-based nucleic acid amplification test was positive in 19% patients. On neuroimaging, hydrocephalus was seen in 44.6% of tubercular meningitis patients, infarcts in 32%, and basal exudates in 12% patients only; coexistent tuberculomas were seen in 53%. Conclusion: Compared with the available literature, the present study showed a smaller percentage of children <5 years of age, stage III tubercular meningitis cases, and typical neuroradiologic findings like hydrocephalus and basal exudates and more tuberculomas associated with tubercular meningitis.

Background: Routine screening of presumptive tuberculosis (TB) patients for HIV was advised by the Treatment and Operational Guidelines of TB in India in 2016. This was in contrast to the earlier policy in which only diagnosed TB cases underwent HIV screening. Keeping this in mind, our study was carried to look at the prevalence of HIV in presumptive TB cases in a tertiary respiratory disease hospital in New Delhi, India. Materials and Methods: This prospective observational study was carried out from 2015 to 2017 in which patients (>18 years of age) attending the outpatient department diagnosed as presumptive TB were enrolled. They underwent sputum examination in Revised National TB Control Programme Designated Microscopy Centre by fluorescence microscopy/Ziehl–Neelsen staining technique for the diagnosis of PTB, and they were taken to Integrated Counselling and Testing Centre in our hospital. Fine-needle aspiration cytology from lymph nodes and pleural or ascitic fluid studies were also done as per requirement for the diagnosis of extrapulmonary tuberculosis. Pretest counseling and HIV test were performed after informed consent. Results: Forty out of 1020 enrolled patients were HIV positive (3.9%). Fifteen out of 617 patients who were not suffering from TB came out to be HIV positive (2.4%). Our strategy led to an enhanced case finding of 15/25 (60%) new HIV-positive patients. Conclusion: Routine HIV screening in presumptive TB patients is a viable model to increase the case finding of HIV patients. [ABSTRACT FROM AUTHOR]

Background. In India, as per the latest diagnostic algorithm, all persons with presumptive pulmonary TB (PPTB) are required to undergo sputum smear examination and chest radiography (CXR) upfront. Those with sputum smear positive, sputum smear negative, but CXR lesions suggestive of TB or those with strong clinical suspicion of TB are expected to undergo Xpert MTB/RIF® assay test (also known as CB-NAAT (cartridge-based nucleic acid amplification test)). Objective. To assess what proportion of PPTB who are undergoing sputum smear examination at microscopy centers of public health facilities have undergone CXR and CB-NAAT. To explore the barriers for uptake of CXR and CB-NAAT from the public health care provider's perspective. Methods. We conducted a sequential explanatory mixed-methods study in Chikkaballapur district of Karnataka State, South India. The quantitative component involved a review of records of PPTB who had undergone sputum smear examination in a representative sample of seven microscopy centers. The qualitative component involved key informant interviews with four medical officers and group interviews with 9 paramedical staff. Results. In February and March 2019, about 732 PPTB had undergone smear examination. Of these, 301 (41%) had undergone CXR and 49 (7%) had undergone CB-NAAT. The proportion of PPTB who had undergone CXR varied across the seven microscopy centers (0% to 89%). CB-NAAT was higher in PPTB from urban areas when compared to rural areas (8% vs. 3%) and in those who were smear positive when compared to smear negative (65% vs. 2%). The major barriers for CXR and CB-NAAT were nonavailability of these tests at all microscopy centers and patients' reluctance to travel to the facilities where CXR and CB-NAAT services are available. Conclusions. CXR and CB-NAAT of PPTB are suboptimal. RNTCP should undertake measures to address these gaps in implementing its latest diagnostic algorithm. [ABSTRACT FROM AUTHOR]

Background: India has the highest burden of both Tuberculosis and MDR‑Tuberculosis based on estimates reported in the Global Tuberculosis Report 2016. The estimates have been revised upwards based on the newer evidence, and the current study was done to estimate the prevalence of bacteriologically positive pulmonary Tuberculosis among the adult population and to provide baseline information for future measurements of Tuberculosis burden and trends. Methods: A cluster‑based sampling design was adopted in 10 districts of Kashmir valley in India. Assuming a prevalence of 217 per lakh population, a design effect of 2.5, a relative precision of 0.25% and the expected participation rate of 80%, a sample size of 49,716 was achieved. A total of 67 clusters were identified where each cluster had 750 subjects aged ≥15 years, and eligible individuals were questioned for pulmonary symptoms suggestive of Tuberculosis. Results: Of the total 42,805 that were interviewed, 3.85% had pulmonary Tuberculosis symptoms. A total of 1539 sputum samples were collected from symptomatic and 1351 chest X‑ rays were done. Cartridge based nucleic acid amplification test (CBNAAT) tests were done on individuals with suspicious X‑ray findings. The prevalence of bacteriologically positive pulmonary Tuberculosis was found to be 147 per 100,000 population. Females are affected more than males, and the age of female Tuberculosis patients is less than that of males. Conclusion: The study is the first survey of its kind providing a baseline for further research in the state. CBNAAT is going to be game‑changer which surmounts the drawbacks of sputum smear microscopy. [ABSTRACT FROM AUTHOR]

Community-level benefits of screening for active tuberculosis (TB) disease remain uncertain. Project Axshya (meaning free of TB) conducted advocacy, communication, social mobilization, and active case finding among vulnerable/marginalized populations of India. Among 15 districts of Jharkhand state, the project was initiated in 36 subdistrict level administrative units — tuberculosis units (TUs) in a staggered manner between April 2013 and September 2014, and continued till the end of 2015. Seven TUs did not implement the project. We assessed the relative change in the quarterly TB case finding indicators (n = 4) after inclusion of a TU within the project. By fitting four multilevel models (mixed-effects maximum likelihood regression using random intercept), we adjusted for secular (over previous five quarters) and seasonal trends, baseline differences within Axshya and non-Axshya TUs, and population size and clustering within districts and within TUs. After inclusion of a TU within the project, we found a significant increase [95% confidence interval (CI)] in TU-level presumptive TB sputum examination rate, new sputum-positive TB Case Notification Rate (CNR), sputum-positive TB CNR, and all forms TB CNR by 12 (5.5, 18.5), 1.1 (0.5, 1.7), 1.3 (0.6, 2.0), and 1.2 (0.1, 2.2) per 100,000 population per quarter, respectively. Overall, the project resulted in an increase (95% CI) in sputum examination and detection of new sputum-positive TB, sputum-positive TB and all forms of TB patients by 22,410 (10,203, 34,077), 2066 (923, 3210), 2380 (1162, 3616), and 2122 (203, 4059), respectively. This provides evidence for implementing project Axshya over and above the existing passive case finding. [ABSTRACT FROM AUTHOR]

Introduction: Genital Tuberculosis (GTB) is an important cause of infertility in developing countries like India. Diagnostic dilemma arises because of atypical clinical presentation, different results on imaging and mixed bag of bacteriological and serological tests such as routine microbiological tests such as Acid Fast Bacilli (AFB) staining and culture are of little significance because of its Paucibacillary nature. Specific and rapid diagnosis using Polymerase Chain Reaction (PCR), early anti-tuberculous treatment and appropriate surgical interventions can improve the results for restoration of female reproductive functions and reduction of procedural and postoperative complications. Aim: To assess the diagnostic performance of PCR, AFB culture and staining in infertility due to Female Genital Tuberculosis (FGTB). Materials and Methods: This observational cross-sectional study was conducted in Microbiology Department of Tertiary Care Hospital, Aurangabad, Maharashtra, India. Relevant clinical specimens were collected using standard procedures from 50 infertile women satisfying inclusion and exclusion criteria; and were evaluated by AFB staining, culture and TB-PCR. Categorical variables were compared using Chi-square test. A p-value <0.05 was considered as statistically significant. Results: Presence of FGTB was found in 6 (12%) cases by using all the investigative parameters alone or in combination. AFB smear alone was positive in 2 (4%), culture in 1 (2%) and TB-PCR in 5 (10%) of cases. Conclusion: PCR has highest sensitivity 100% with negative predictive value of 100% compared to microscopy and culture. Therefore, when the clinical suspicion is high and smear and culture results are negative, PCR is the method of choice for identifying the infection in FGTB cases. [ABSTRACT FROM AUTHOR]

Hemoptysis is a common respiratory symptom. One of the most common cause for hemoptysis in India is pulmonary tuberculosis. Pulmonary tuberculosis is more common in young and usually present with fever, cough and hemoptysis. Chest x ray usually shows upper lobe lesions. When sputum examination for AFB smear is negative and chest radiology is not typical of tuberculosis further investigations are indicated for definitive diagnosis. We report a rare case of pleomorphic carcinoma of lung in a young female mimicking pulmonary tuberculosis. Definitive diagnosis was established by biopsy from the lung lesion. [ABSTRACT FROM AUTHOR]

Background Axshya SAMVAD is an active tuberculosis (TB) case finding (ACF) strategy under project Axshya (Axshya meaning ‘free of TB’ and SAMVAD meaning ‘conversation’) among marginalized and vulnerable populations in 285 districts of India. Objectives To compare patient characteristics, health seeking, delays in diagnosis and treatment initiation among new sputum smear positive TB patients detected through ACF and passive case finding (PCF) under the national TB programme in marginalized and vulnerable populations between March 2016 and February 2017. Methods This observational analytic study was conducted in 18 randomly sampled Axshya districts. We enrolled all TB patients detected through ACF and an equal number of randomly selected patients detected through PCF in the same settings. Data on patient characteristics, health seeking and delays were collected through record review and patient interviews (at their residence). Delays included patient level delay (from eligibility for sputum examination to first contact with any health care provider (HCP)), health system level diagnosis delay (from contact with first HCP to TB diagnosis) and treatment initiation delays (from diagnosis to treatment initiation). Total delay was the sum of patient level, health system level diagnosis delay and treatment initiation delays. Results We included 234 ACF-diagnosed and 231 PCF-diagnosed patients. When compared to PCF, ACF patients were relatively older (≥65 years, 14% versus 8%, p = 0.041), had no formal education (57% versus 36%, p<0.001), had lower monthly income per capita (median 13.1 versus 15.7 USD, p = 0.014), were more likely from rural areas (92% versus 81%, p<0.002) and residing far away from the sputum microscopy centres (more than 15 km, 24% versus 18%, p = 0.126). Fewer patients had history of significant loss of weight (68% versus 78%, p = 0.011) and sputum grade of 3+ (15% versus 21%, p = 0.060). Compared to PCF, HCP visits among ACF patients was significantly lower (median one versus two HCPs, p<0.001). ACF patients had significantly lower health system level diagnosis delay (median five versus 19 days, p = 0.008) and the association remained significant after adjusting for potential confounders. Patient level and total delays were not significantly different. Conclusion Axshya SAMVAD linked the most impoverished communities to TB care and resulted in reduction of health system level diagnosis delay. [ABSTRACT FROM AUTHOR]

Background: According to Revised National Tuberculosis Control Program (RNTCP), diagnosis of pulmonary tuberculosis (TB) in India requires examination of two sputum samples collected over 2 days, that is, "spot" and next day "morning" samples. Objective: To assess the feasibility of diagnosing pulmonary TB by examining two spot sputum samples in 1 day and to compare this approach with the current RNTCP protocol. Materials and Method: A total of 375 subjects having cough >2 weeks were enrolled into the study. Three sputum samples were collected from each of the study participant; first spot (S1), second extra-spot (S2) sample 1 h after collection of the first sample, and third morning (M) sample collected next day morning. These specimens were subjected to standard sputum smear microscopy for acid-fast bacilli as per RNTCP guidelines. For 1-day protocol, results of "S1 and S2" samples and for 2-day protocol results of "S1 and M" samples were considered. Results: The number of sputum-positive pulmonary TB cases diagnosed with standard 2-day protocol was 119, whereas the experimental 1-day protocol diagnosed 120 cases (P = 0.7). Comparing with standard 2-day protocol, this new 1-day protocol had sensitivity 98.32%, specificity 100%, positive predictive value 100%, and negative predictive value 99.17%. Conclusion: Single-day method can be adopted as the standard diagnostic approach for pulmonary TB after large-scale multicenter randomized controlled trials. [ABSTRACT FROM AUTHOR]

Introduction: There is lack of information on the proportion of new smear—positive pulmonary tuberculosis (PTB) patients treated with a 6-month thrice-weekly regimen under Revised National Tuberculosis Control Programme (RNTCP) who develop recurrent TB after successful treatment outcome. Objective: To estimate TB recurrence among newly diagnosed PTB patients who have successfully completed treatment and to document endogenous reactivation or re-infection. Risk factors for unfavourable outcomes to treatment and TB recurrence were determined. Methodology: Adult (aged ≥ 18 yrs) new smear positive PTB patients initiated on treatment under RNTCP were enrolled from sites in Tamil Nadu, Karnataka, Delhi, Maharashtra, Madhya Pradesh and Kerala. Those declared “treatment success” at the end of treatment were followed up with 2 sputum examinations each at 3, 6 and 12 months after treatment completion. MIRU-VNTR genotyping was done to identify endogenous re-activation or exogenous re-infection at TB recurrence. TB recurrence was expressed as rate per 100 person-years (with 95% confidence interval [95%CI]). Regression models were used to identify the risk factors for unfavourable response to treatment and TB recurrence. Results: Of the1577 new smear positive PTB patients enrolled, 1565 were analysed. The overall cure rate was 77% (1207/1565) and treatment success was 77% (1210 /1565). The cure rate varied from 65% to 86%. There were 158 of 1210 patients who had TB recurrence after treatment success. The pooled TB recurrence estimate was 10.9% [95%CI: 0.2–21.6] and TB recurrence rate per 100 person–years was 12.7 [95% CI: 0.4–25]. TB recurrence per 100 person–years varied from 5.4 to 30.5. Endogenous reactivation was observed in 56 (93%) of 60 patients for whom genotyping was done. Male gender was associated with TB recurrence. Conclusion: A substantial proportion of new smear positive PTB patients successfully treated with 6 –month thrice-weekly regimen have TB recurrence under program settings. [ABSTRACT FROM AUTHOR]

Background: Globally, India has the world’s highest burden of multidrug-resistant tuberculosis (MDR-TB). Programmatic Management of Drug Resistant TB (PMDT) in India began in 2007 and nationwide coverage was achieved in early 2013. Poor initial microbiological outcomes under the Revised National Tuberculosis Control Programme (RNTCP) prompted detailed analysis. This is the first study on factors significantly associated with poor outcomes in MDR-TB patients treated under the RNTCP. Objective: To evaluate initial sputum culture conversion, culture reversion and final treatment outcomes among MDR-TB patients registered in India from 2007 to early 2011 who were treated with a standard 24-month regimen under daily-observed treatment. Methods: This is a retrospective cohort study. Clinical and microbiological data were abstracted from PMDT records. Initial sputum culture conversion, culture reversion and treatment outcomes were defined by country adaptation of the standard WHO definitions (2008). Cox proportional hazards modeling with logistic regression, multinomial logistic regression and adjusted odds ratio was used to evaluate factors associated with interim and final outcomes respectively, controlling for demographic and clinical characteristics. Results: In the cohort of 3712 MDR-TB patients, 2735 (73.6%) had initial sputum culture conversion at 100 median days (IQR 92–125), of which 506 (18.5%) had culture reversion at 279 median days (IQR 202–381). Treatment outcomes were available for 2264 (60.9%) patients while 1448 (39.0%) patients were still on treatment or yet to have a definite outcome at the time of analysis. Of 2264 patients, 781 (34.5%) had treatment success, 644 (28.4%) died, 670 (29.6%) were lost to follow up, 169 (7.5%) experienced treatment failure or were changed to XDR-TB treatment. Factors significantly associated with either culture non-conversion, culture reversion and/or unfavorable treatment outcomes were baseline BMI < 18; ≥ seven missed doses in intensive phase (IP) and continuation phase (CP); cavitary disease; prior treatment episodes characterized by re-treatment regimen taken twice, longer duration and more episodes of treatment; any weight loss during treatment; males and additional resistance to first line drugs (Ethambutol, Streptomycin). In a subgroup of 104 MDR-TB patients, 62 (59.6%) had Ofloxacin resistance among whom only 25.8% had treatment success, half of the success (54.8%) seen in Ofloxacin sensitive patients. Baseline susceptibility to Ofloxacin (HR 2.04) and Kanamycin (HR 4.55) significantly doubled and quadrupled the chances for culture conversion respectively while baseline susceptibility to Ofloxacin (AOR 0.37) also significantly reduced the odds of unfavorable treatment outcomes (p value ≤0.05) in multinomial logistic regression model. Conclusion: India’s initial MDR-TB patients’ cohort treated under the RNTCP experienced poor treatment outcomes. To address the factors associated with poor treatment outcomes revealed in our study, a systematic multi-pronged approach would be needed. A series of policies and interventions have been developed to address these factors to improve DR-TB treatment outcomes and are being scaled-up in India. [ABSTRACT FROM AUTHOR]

Background: High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics.Methods: Retrospective analysis of eight years' data from an HIV Clinic in a TB hospital in India. Patients underwent chest x-ray, sputum examination, USG abdomen and routine blood tests at entry to HIV care. Case forms were scrutinized for diagnosis of TB, USG findings and CD4 cell counts. Abdominal TB was classified as probable or possible TB. Probable TB was based on presence of two major USG (abdomen) findings suggestive of active TB, or one major USG finding with at least two minor USG findings or at least two symptoms, or any USG finding with microbiologically confirmed active TB at another site. Possible TB was based on the presence of one major USG finding, or the presence of two minor USG findings with at least two symptoms. Bacteriological confirmation was not obtained.Results: Eight hundred and eighty-nine people PLHIV underwent a baseline USG abdomen. One hundred and thirteen of 340 cases already diagnosed with TB and 87 of the 91 newly diagnosed with TB at time of HIV clinic registration had abdominal TB. Non-abdominal symptoms like weight loss, fever and cough were seen in 53% and 22% cases had no symptoms at all. Enlarged abdominal lymph nodes with central caseation, ascitis, splenic microabsesses, bowel thickening and hepatosplenomegaly were the USG findings in these cases.Conclusions: Abdominal TB is a frequent TB site in PLHIV presenting with non-abdominal symptoms. It can be easily detected on basis of features seen on a simple abdominal ultrasound. Abdominal USG should be essential part of intensified TB case finding algorithms for HIV infected people living in high TB burden settings. [ABSTRACT FROM AUTHOR]

Nearly half of the smear negative pulmonary TB in National TB Programme remain undetected in Haryana (north Indian state), probably due to poor access to chest radiography. A corporate hospital stepped into fill this infrastructure gap in Rewari district of Haryana by sending a mobile van with digital x-ray facilities and paramedic staff. The staff of the public health facility coordinated with the eligible patients and ensured that they visited on the designated day. The District TB Officer interpreted the x-ray and made decisions about diagnosis and treatment. The support was provided between May and Dec 2014 in seven public health centres (primary/secondary level) of the district. A total of 355 patie-nts were examined, of whom 122 (34.4%) were diagnosed as smear negative pulmonary TB and started on treatment according to programme guidelines. This public-private partnership needs to be scaled-up and better designed studies are required to assess community-level impact and cost-effectiveness. [ABSTRACT FROM AUTHOR]

Background & objectives: Mycobacterium tuberculosis complex may sometimes not be detected in sputum samples of suspected multidrug-resistant tuberculosis (MDR-TB) patients by line probe assay (LPA) even though they are smear positive for acid-fast bacilli (AFB). This retrospective analysis was attempted to understand and document our experience with LPA for detection of M. tuberculosis complex and diagnosis of MDR-TB under programmatic conditions. Methods: One thousand two hundred and ninety four sputum samples of MDR-TB suspects that were smear positive for AFB, and received from February to November 2013, were tested by LPA for the presence of M. tuberculosis complex and resistance to isoniazid (INH) and rifampicin as per the diagnostic mandate of an accredited reference laboratory. As per the mandate, those samples that were negative for M. tuberculosis complex were cultured, and the growth again tested by LPA. A retrospective analysis of the results was carried out. Results: M. tuberculosis complex could be detected in 1217 (94.04%) but not in 77 (5.9%) of smear-positive sputum samples. Of the 1217 positive samples, 232 (19.1%) were MDR, 130 (10.6%) were rifampicin monoresistant and 101 (8.3%) were INH monoresistant. Seven hundred and fifty four (61.9%) strains were found to be pansensitive. Overall, 5.1 per cent of the sputum samples were negative for M. tuberculosis complex by LPA and culture. In at least 10 (0.77%) sputum samples smear positive for AFB, M. tuberculosis complex could not be identified by LPA though M. tuberculosis was present, as evidenced by culture positivity. Interpretation & conclusions: LPA is a robust technique for diagnosis of drug-resistant TB that has provided the basis for rapid and effective control of drug-resistant TB in India. While the reasons for concomitantly negative LPA and culture results of smear-positive sputum samples from MDR-TB suspects may be many, the possible presence of non-tubercular mycobacteria in these samples and the likelihood of inappropriate therapy in these patients cannot be ruled out. Addition of culture to the diagnostic algorithm may enhance the diagnostic yield. [ABSTRACT FROM AUTHOR]

Introduction: India has one of the highest tuberculosis (TB) burdens globally, accounting for 20% of the new 8.6 million TB cases annually. While the burden of childhood TB in India is not known, regional data from the World Health Organization WHO) indicate that sputum microscopy smear-positive TB in children (<14 years old) accounts for 0.6%-3.6% of all reported cases. Material and methods: All the contact aged less than 6 years of sputum positive adult patients diagnosed at RNTCP DOTS centre was taken in the study & to detect TB infection or disease. Children under the age of 6 years who were household contacts of diagnosed adults with pulmonary tuberculosis constituted the study population. Household contact was defined as a child living in the same house as the adult patient. Results: In our study there was 86 children, out of which 49 children had malnutrition i.e 56.9%, malnutrition was classified by IAP classification, no malnutrition in 28.6%, mild malnutrition =55.8%, severe malnutrition = 15.7%. Whereas, In study of M.sigh129, this study was about the prevalence of tuberculosis infection among children in household contact with adults having pulmonary tuberculosis, and identify the possible risk factors. malnutrition was important risk factor, all the children was classified as per IAP classification, no malnutrition =34.2%, mild malnutrition =55.8%, severe malnutrition = 15.7%. Conclusion: Contact tracing should be done routinely in evaluation of childhood-tuberculosis. [ABSTRACT FROM AUTHOR]

Early case identification and prompt treatment of new sputum smear positive case are important to reduce the spread of tuberculosis (TB). Present study was planned to study the associated factors for duration to contact the health facility since appearance of symptoms and treatment default. Methodology. It was prospective cohort study of TB patients already registered for treatment in randomly selected TB units (TUs) in Himachal Pradesh, India. Relative risk (RR) was calculated as risk estimate to find out the explanatory variables for early contact and default. Results. Total 1607 patients were recruited and 25 (1.5%) defaulted treatment. Patients from nuclear family (aRR: 1.37; 1.09-1.73), ashamed of TB (aRR: 1.32; 1.03-1.70), wishing to disclose disease status (aRR: 1.79; 1.43-2.24), but aware of curable nature (aRR: 1.67; 1.17-2.39) and preventable (aRR: 1.35; 1.07-1.70) nature of disease, contacted health facility early since appearance of symptoms. Conclusion. Better awareness and less misconceptions about disease influences the early contact of health facility and low default rate in North India. [ABSTRACT FROM AUTHOR]

Background: Tuberculosis (TB) remains as an important public health problem in India. Awareness about the disease, its diagnosis, and treatment among public will help in controlling the killer disease. This study aims at arriving at an educational diagnosis about TB in an urban poor community. Materials and Methods: A cross-sectional study was conducted in an urban slum in South India using a structured, pretested questionnaire. Domains identified were knowledge about TB, symptoms, spread, diagnosis, treatment, and prevention of TB. Results: A total of 395 households were interviewed. Of them, 370 (94%) respondents had heard about TB. Regarding the symptoms of TB, 82% were aware that cough is a symptom of TB. Among the 79% of study subjects who reported any test to diagnose TB, sputum examination as a method of diagnosis was known to only 40%. However, 84% of the subjects were aware of the free treatment available for TB under National program. Conclusion: Level of awareness about TB among urban poor in a slum area is good. Knowledge about "free treatment" and "duration of treatment" has to be stressed during health education activities. [ABSTRACT FROM AUTHOR]

3D printing technology can produce complex objects directly from computer aided digital designs. The technology has traditionally been used by large companies to produce fit and form concept prototypes ('rapid prototyping') before production. In recent years however there has been a move to adopt the technology as full-scale manufacturing solution. The advent of low-cost, desktop 3D printers such as the RepRap and Fab@Home has meant a wider user base are now able to have access to desktop manufacturing platforms enabling them to produce highly customised products for personal use and sale. This uptake in usage has been coupled with a demand for printing technology and materials able to print functional elements such as electronic sensors. Here we present formulation of a simple conductive thermoplastic composite we term 'carbomorph' and demonstrate how it can be used in an unmodified low-cost 3D printer to print electronic sensors able to sense mechanical flexing and capacitance changes. We show how this capability can be used to produce custom sensing devices and user interface devices along with printed objects with embedded sensing capability. This advance in low-cost 3D printing with offer a new paradigm in the 3D printing field with printed sensors and electronics embedded inside 3D printed objects in a single build process without requiring complex or expensive materials incorporating additives such as carbon nanotubes.

Background: The Revised National Tuberculosis Control Program (RNTCP) of India recommends follow-up sputum smear examination at two months into the continuation phase of treatment. The main intent of this (mid-CP) follow-up is to detect patients not responding to treatment around two-three months earlier than at the end of the treatment. However, the utility of mid-CP follow-up under programmatic conditions has been questioned. We undertook a multi-district study to determine if mid-CP follow-up is able to detect cases of treatment failures early among all types of patients with sputum smear-positive TB. Methodology: We reviewed existing records of patients with sputum smear-positive TB registered under the RNTCP in 43 districts across three states of India during a three month period in 2009. We estimated proportions of patients that could be detected as a case of treatment failure early, and assessed the impact of various policy options on laboratory workload and number needed to test to detect one case of treatment failure early. Results: Of 10055 cases, mid-CP follow-up was done in 6944 (69%) cases. Mid-CP follow-up could benefit 117/8015 (1.5%) new and 206/2040 (10%) previously-treated sputum smear-positive cases by detecting their treatment failure early. Under the current policy, 31 patients had to be tested to detect one case of treatment failure early. All cases of treatment failure would still be detected early if mid-CP follow-up were discontinued for new sputum smear-positive cases who become sputum smear-negative after the intensive-phase of treatment. This would reduce the related laboratory workload by 69% and only 10 patients would need to be tested to detect one case of treatment failure early. Conclusion: Discontinuation of mid-CP follow-up among new sputum smear-positive cases who become sputum smearnegative after completing the intensive-phase of treatment will reduce the laboratory workload without impacting overall early detection of cases of treatment failure.

Background & objectives: mRNA is more rapidly destroyed in cells than rRNA or genomic DNA, an assay targeting bacterial mRNA would provide a better guide to mycobacterial viability than amplification tests directed at DNA or rRNA targets. This study was carried out to standardize reverse transcriptase PCR (RT-PCR) targeting 85B gene for the rapid detection of viable Mycobacterium tuberculosis from sputum specimens of suspected TB patients at Chennai, South India and to detect MDR-TB circulating in this population. Methods: Sputum samples from clinically suspected tuberculosis patients (n=301) and 78 controls were included in the study. The sputum samples were collected in sterile diethyl pyrocarbonate (DEPC) treated containers and transported in ice to the laboratory within 2 h to prevent degradation of RNA. RT-PCR targeting 85B gene, mycobacteriai culture and phenotypic drug susceptibility testing for the first line drugs streptomycin (S), isoniazid (H), rifampicin (R), ethambutol (E) and pyrazinamide (Z) were performed by BACTEC microMGIT culture system for all the sputum specimens. Results: All the 78 controls were negative for culture and RT-PCR. Among the 301 sputum specimens from patients, 231 (76.8%) were RT-PCR positive and 70 (23.2%) were negative. There were 166 M. tuberculosis isolates, of which 11 (2.9%) were MDR-TB, 33 (8.7%) were polyresistant, 31 (8.2%) were monoresistant and 91 (30.2%) were sensitive to all five first line anti-tuberculous drugs by phenotypic drug susceptibility testing. Monoresistance was higher with Z [20 (20.8%)], followed by S [6 (3%)]. Interpretation & conclusions: RT-PCR targeting 85B gene of M. tuberculosis was a specific, rapid, reliable technique to detect the M. tuberculosis directly from sputum specimens. Our results showed that 2.9 per cent of M. tuberculosis isolates in the study population of Chennai were MDR. [ABSTRACT FROM AUTHOR]

Background & objectives: The prevalence of multidrug-resistant tuberculosis (MDR-TB) is increasing throughout the world. Although previous treatment for TB is the most important risk factor for development of MDR-TB, treatment-naive patients are also at risk due to either spontaneous mutations or transmission of drug-resistant strains. We sought to ascertain the prevalence of MDR-TB among new cases of sputum-positive pulmonary TB. Methods: This was a prospective, observational study involving newly diagnosed cases of sputum-positive pulmonary tuberculosis diagnosed between 2008 and 2009 carried out in New Delhi, India. All sputum-positive TB cases were subjected to mycobacterial culture and first-line drug-susceptibility testing (DST). MDR-TB was defined as TB caused by bacilli showing resistance to at least isoniazid and rifampicin. Results: A total of 218 cases of sputum-positive pulmonary tuberculosis were enrolled between 2008 and 2009. Of these, 41 cases had negative mycobacterial cultures and DST was carried out in 177 cases. The mean age of the patients was 27.8 ± 10.2 yr; 59 patients (27%) were female. All patients tested negative for HIV infection. Out of 177 cases, two cases of MDR-TB were detected. Thus, the prevalence of MDRTB among newly diagnosed pulmonary tuberculosis patients was 1.1 per cent. Interpretation & conclusions: MDR-TB prevalence is low among new cases of sputum-positive pulmonary TB treated at primary care level in Delhi. Nation-wide and State-wide representative data on prevalence of MDR-TB are lacking. Efforts should be directed towards continued surveillance for MDR-TB among newly diagnosed TB cases.

Background: Default remains an important challenge for the Revised National Tuberculosis Control Programme, which has achieved improved cure rates. Objectives: This study describes the pattern of time of default in patients on DOTS. Settings and Design: Tuberculosis Unit in District Tuberculosis Centre, Yavatmal, India; Retrospective cohort study. Materials and Methods: This analysis was done among the cohort of patients of registered at the Tuberculosis Unit during the year 2004. The time of default was assessed from the tuberculosis register. The sputum smear conversion and treatment outcome were also assessed. Statistical Analysis: Kaplan-Meier plots and log rank tests. Results: Overall, the default rate amongst the 716 patients registered at the Tuberculosis Unit was 10.33%. There was a significant difference in the default rate over time between the three DOTS categories (log rank statistic= 15.49, P=0.0004). Amongst the 331 smear-positive patients, the cumulative default rates at the end of intensive phase were 4% and 16%; while by end of treatment period, the default rates were 6% and 31% in category I and category II, respectively. A majority of the smear-positive patients in category II belonged to the group 'treatment after default' (56/95), and 30% of them defaulted during re-treatment. The sputum smear conversion rate at the end of intensive phase was 84%. Amongst 36 patients without smear conversion at the end of intensive phase, 55% had treatment failure. Conclusions: Patients defaulting in intensive phase of treatment and without smear conversion at the end of intensive phase should be retrieved on a priority basis. Default constitutes not only a major reason for patients needing re-treatment but also a risk for repeated default. [ABSTRACT FROM AUTHOR]

Background: Reaching a correct diagnosis is a challenge for physicians treating any of the 30% to 50% of pulmonary tuberculosis patients who have negative sputum cultures or who present with no sputum. Flexible bronchoscopy acquires special importance for these cases for whom empirical anti-tuberculosis therapy is the only option left. In our study we aimed to assess the diagnostic yield of flexible bronchoscopy in patients, suspected to have tuberculosis, whose sputum smears were negative. Methodology: In our hospital-based cross-sectional study, 42 patients were enrolled by consecutive sampling. Flexible bronchoscopy and selective bronchial washings were done in all patients. Results: Bronchoscopy lavage smears were positive for M. tuberculosis in 10 (23.8%) patients. Fifteen (35.7%) patients had positive culture. Conclusion: Flexible bronchoscopy has an important role in the diagnosis of patients suspected to have tuberculosis, whose sputum smears are negative or who can not produce sputum.

Background: Direct sputum smear microscopy for tuberculosis (TB) lacks sensitivity for the detection of acid fast bacilli. Sputum pretreatment procedures may enhance sensitivity. We did a pilot study to compare the diagnostic accuracy and incremental yield of two short-duration (<1 hour) sputum pretreatment procedures to optimize direct smears among patients with suspected TB at a referral hospital in India. Methodology/Findings: Blinded laboratory comparison of bleach and universal sediment processing (USP) pretreated centrifuged auramine smears to direct Ziehl-Neelsen (ZN) and direct auramine smears and to solid (Loweinstein-Jensen (LJ)) and liquid (BACTEC 460) culture. 178 pulmonary and extrapulmonary TB suspects were prospectively recruited during a one year period. Thirty six (20.2%) were positive by either solid or liquid culture. Direct ZN smear detected 22 of 36 cases and direct auramine smears detected 26 of 36 cases. Bleach and USP centrifugation detected 24 cases each, providing no incremental yield beyond direct smears. When compared to combined culture, pretreated smears were not more sensitive than direct smears (66.6% vs 61.1 (ZN) or 72.2 (auramine)), and were not more specific (92.3% vs 93.0 (ZN) or 97.2 (auramine). Conclusions/Significance: Short duration sputum pretreatment with bleach and USP centrifugation did not increase yield as compared to direct sputum smears. Further work is needed to confirm this in a larger study and also determine if longer duration pre-treatment might be effective in optimizing smear microscopy for TB. [ABSTRACT FROM AUTHOR]

Objective To review the characteristics of public-private mix projects in India and their effect on case notification and treatment outcomes for tuberculosis. Design Literature review. Data sources Review of surveillance records from Indian tuberculosis programme project, evaluation reports, and medical literature for public-private mix projects in India. Data extraction Project characteristics, tuberculosis case notification of new patients with sputum smear results positive for acid fast bacilli, and treatment outcome. Data synthesis Of 24 identified public-private mix projects, data were available from 14 (58%), involving private practitioners, corporations, and non-governmental organisations. In all reviewed projects, the public sector tuberculosis programme provided training and supervision of private providers. Among the five projects with available data on historical controls, case notification rates were higher after implementation of a public-private mix project. Among seven projects involving private practitioners, 2796 of 12 147 (23%) new patients positive for acid fast bacilli were attributed to private providers. Corporate based and non-governmental organisations served as the main source for tuberculosis programme services in seven project areas, detecting 9967 new patients positive for acid fast bacilli. In nine of 12 projects with data on treatment outcomes, private providers exceeded the programme target of 85% treatment success for new patients positive for acid fast bacilli. Conclusions Public-private mix activities were associated with increased case notification, while maintaining acceptable treatment outcomes. Collaborations between public and private providers of health care hold considerable potential to improve tuberculosis control in India. [ABSTRACT FROM AUTHOR]

Background: India is one of the high tuberculosis (TB) burden countries in the world. India ranks second in harboring multi drug resistant (MDR)-TB cases. About 50,000 of MDR cases are recorded in retreatment pulmonary TB cases. This study was conducted in a tertiary care facility (Government General and Chest Hospital) in Hyderabad, India. Objectives: Toassess: Proportion of the TB patients having MDR-TB at the initiation of retreatment regimen; the prevalence of isoniazid (INH) resistance in this geographical area. Materials and Methods: An analytical, observational, prospective cohort study of patients attending the out-patient department from December 2010 to March 2011. Results: Sputum samples from 100 patients were subjected to acid fast bacilli (AFB) culture and drug sensitivity testing. Of these, 28 (28%) were MDR-TB, 42 (42%) were non-MDR-TB and 39% being INH resistance. Conclusions: In conclusion, one third of the retreatment pulmonary TB cases attending a tertiary care institute for TB will be MDR-TB at the initiation of treatment and there is a need to include ethambutol in the continuation phase of new TB case treatment in view of high INH resistance.

Abstract   Haemophilus influenzae type b meningitis has been reported predominantly among infants who have not completed the primary immunization series, whereas infection by capsular f has been reported mostly in patients with significant underlying diseases. The present study analyses H. influenzae type b & f infection among 25 unvaccinated patients with respiratory tract infections and symptoms of meningitis by PCR. 5/7 isolates from CSF sample were capsular type b; whereas capsular type f was detected in 2/10 and 5/8 isolates from throat swab and sputum samples, respectively. Rest 13 strains were negative for both the capsular types. To conclude, in India where H. influenzae type b conjugate vaccine is not included in national immunization program, individuals with respiratory tract infections and meningitis are at a greater risk of developing infection with H. influenzae type b strains along with other capsular types and non-capsular types.

Background: One major barrier to achieve goal of tuberculosis (TB) control program globally, is the stigma attached to the disease. Perceived stigma can delay sputum test in time. Delay will lead to spread of infection in the community. There is no scientific information available in India exactly looking into the association between delay in sputum examination and stigma., Aim: We conducted a study in rural West Bengal among persons with cough for 2 weeks or more to assess their level of stigma, its influence on delay for sputum test and identify factors those shape the level of stigma., Methods: A community based cross sectional survey was conducted from February to June 2015 in West Bengal, India. We interviewed 135 persons of 15-60 years. Data were collected using a pretested structured questionnaire. Chi-square and logistic regression analysis were done using SPSS 23.0 statistical software., Results: Among the 'lower stigma' group (score 4-24), 'delay' (14-25 days) is found among 46.2% respondents and 'much delay' (26-120 days) among 53.8%. Among the 'higher stigma' (score 25-36) group, 'delay' is found among 20.5% respondents and 'much delay' among 79.5%. Persons with lower stigma are 0.17 times likely to delay than persons with higher stigma [adjusted odds ratio (AOR): 0.17 (0.044-0.668), p=0.011)]. Important influencers of stigma are caste [AOR: 5.90 (1.66-20.90), p=0.006], number of family members [AOR: 3.46 (1.08-11.06), p=0.009] and residence in urban or rural [AOR: 3.97 (1.03-15.27), p=0.045]., Conclusion: Revised National Tuberculosis Control Program in India should de-stigmatize the community giving priorities to lower castes, big families and rural areas., (Copyright © 2017 Tuberculosis Association of India.

The article presents the results of a study conducted by the authors on the impact of health education on the knowledge and awareness of students at the Kaniyambadi Higher Secondary School in Vellore, India on tuberculosis in July 2008. Out of 271 students, 77% were aware that tuberculosis is caused by bacteria while 85% believe it can transmit from person to person. Only 28% were aware that treatment lasts six to nine months. Another 52% were aware that sputum test was the common diagnostic test.

The article discusses a study that uses a nitrate reductase assay (NRA) to test the rapid and inexpensive drug susceptibility of Mycobacterium tuberculosis from western India. The study compares 80 strains of M. tuberculosis isolated from sputum samples of pulmonary tuberculosis patients through NRA and absolute concentration method. It reveals the potential of the NRA to be a useful tool for rapid DST of M. tuberculosis.

Looks the shortcomings of direct observed treatments short course (DOTS) program in the management of tuberculosis. Outdated diagnostic tools and shortcomings in the DOTS program; Case detection for DOTS, which relies on sputum smear microscopy, a 19th century tool; Current detection rate of only 37%; Call for new tests to improve diagnosis and new drugs.

Background: Tuberculosis (TB) continues to pose a major global health problem and thus intensive action is needed to control and ultimately eliminate the disease., Methods: An active case finding (ACF) survey was conducted in the urban slum areas of the R-South Municipal Ward of Mumbai City for a period of two months from June to July 2012. Micro planning for survey was done by District Tuberculosis Officer and Medical Officer of Health of R-South ward. The entire health post staffs of R-South ward were trained to perform the survey. TB suspects were identified by trained community health volunteers during their home to home visit. These suspects were referred to the designated microscopy centers (DMCs) for sputum examination and those diagnosed with TB were put on anti-TB treatment., Results: A total of 278 TB suspects were identified on enquiring on the presence of symptoms suggestive of TB. Out of them 221(79.5%) patients got tested for sputum examination. Sputum positive TB was diagnosed in 29 suspects and the sputum positivity rate was 13.1%, which was slightly higher than the passive case finding norms of 10% as prescribed under Revised National TB Control Program., Conclusion: Active case finding for tuberculosis in the general community was discouraged for several decades because of high costs of implementation. However, results of the survey suggest that periodic ACF should be incorporated in populations wherever tuberculosis incidence / prevalence is high as there was a definite improvement in the case detection rate.
