Trends of Private Drugs' Sales and Costs Incurred by Patients on Anti-tuberculosis Drugs in Selected Districts of Jharkhand (2022): Results From Sub-national TB-Free Certification.

BACKGROUND: The government of India is committed to eliminating tuberculosis (TB) by 2025 under the National Tuberculosis Elimination Programme which provides free investigations and treatment as well as incentives for nutritional support during their treatment course. Many TB patients prefer to seek treatment from the private sector which sometimes leads to financial constraints for the patients. Our study aims to find the burden of TB patients in the private sector and the expenses borne by them for their treatment. METHODOLOGY: Sales data of rifampicin-containing formulation drug consumption in the private sector of six districts of Jharkhand was collected from Clearing and Forwarding agencies. Based on the drug sales data, the total incurring costs of the drugs, total number of patients, and cost per patient seeking treatment from the private sector were calculated for the year 2015-2021. ANOVA and the post hoc test (Tukey honestly significant difference (HSD)) were applied for analysis. RESULTS:  There was a marked difference amongst all the districts in relation to all the variables namely total costs, cost per patient, and total private patients seeking treatment from the private sector which was statistically significant (p < 0.001). East Singhbhum had the highest out-of-pocket expense and private patients as compared to all six districts. Lohardaga showed the sharpest decline in total private patients from 2015 to 2021. The average cost borne by private patients in 2015 was INR 1821 (95% CI 1086 - 2556) which decreased to INR 1033 (95% CI 507 - 1559) in 2021. CONCLUSION: From the study, it was concluded that the purchase of medicines for TB treatment from the private sector is one of the essential elements in out-of-pocket expenditure (OOPE) borne by TB patients. Hence, newer initiatives should be explored to foresee the future OOPE borne by the patients and decrease OOPE-induced poverty.

Association of Wilms tumor-1 protein in urinary exosomes with kidney injury: a population-based cross-sectional study.

Objective: Loss of Wilms tumor-1 (WT1) protein, a podocytopathy marker, through urine exosome (uE), could be an early indication of kidney injury. We examined WT1 in uE (uE-WT1), along with other urine markers of glomerular and kidney tubule injury, in individuals without chronic kidney disease (CKD). Methodology: The cross-sectional study included individuals who reported having no evidence of chronic kidney disease (CKD). Albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) were used to assess kidney function. eGFR was calculated using the 2009 CKD-EPI (CKD-Epidemiological) equation. WT1 was analyzed in uE from humans and Wistar rats (before and after the 9th week of diabetes, n = 20). uE-WT1, urinary neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) were estimated using ELISA. The Kruskal-Wallis H test, Mann-Whitney U test, and stepwise multivariable linear regression were performed. Results: Urine NGAL and ACR increase with uE-WT1 quartiles (n = 146/quarter). Similarly, uE-WT1, KIM-1, and NGAL were positively associated with ACR. Furthermore, KIM-1, NGAL, and uE-WT1 correlated with ACR. uE-WT1 outperformed KMI-1 and NGAL to explain ACR variability (25% vs. 6% or 9%, respectively). Kidney injury in streptozotocin-induced diabetic rats was associated with a significant rise in uE-WT1. Moreover, the findings were confirmed by the histopathology of kidney tissues from rats. Conclusion: uE-WT1 was strongly associated with kidney function in rats. In individuals without CKD, uE-WT1 outperformed NGAL as a determinant of differences in ACR.

Occupational Heat Stress and Kidney Health in Salt Pan Workers.

Introduction: Work in heat affects millions of workers. Although kidney function in agricultural workers is increasingly researched, nonagricultural studies are scarce. In coastal salt pans, the absence of occupational exposures to pesticides and other toxicants allows assessment of heat stress alone. Methods: Seven Indian salt pans were surveyed from 2017 to 2020. Job-specific workload was assessed. Heat stress was characterized as exceeding the wet bulb globe temperature (WBGT)-threshold limit value (TLV) for high and moderate workloads. Preshift and postshift heart rates (HRs), tympanic temperatures, and urine specific gravity (USG) were measured for 352 workers, as were sweat rates (SwR), serum creatinine (SCr), serum uric acid, and urine dipstick. Estimated glomerular filtration rate (eGFR; ml/min per 1.73 m2) was computed. Heat-strain symptoms were assessed using questionnaires. Results: The mean WBGT was 30.5 ± 1.3 °C (summer) and 27.8 ± 1.9 °C (winter). Water intake during the workday was low, median was one Litre, and most workers (87%) exceeded the TLV for heat stress. Dehydration-related symptoms were frequent in those with high-heat stress, as were cross-shift increases in temperature (≥1°C; 15%), a high USG (≥1.020; 28%), and a high SwR (≥1 l/h; 53%). An eGFR of 60 to 89 ml/min per 1.73 m2 was observed in 41% of all workers examined, and 7% had eGFR below 60 ml/min per 1.73 m2. The odds ratio for eGFR <90 ml/min per 1.73 m2 in workers exceeding the TLV, compared to workers below this limit, adjusted for age and gender was 2.9 (95% CI: 1.3-6.4). Conclusion: Workplace interventions to prevent heat stress and dehydration in the salt pans and other at-risk industries are urgently required. The findings strengthen the notion that high-heat stress and limited hydration is a risk factor for kidney dysfunction.

Community Dynamics and Engagement Strategies in Establishing Demographic Development and Environmental Surveillance Systems: A Multi-Site Report from India.

BACKGROUND: Six diverse Demographic Development and Environmental Surveillance System (DDESS) sites were established in urban slum, urban resettlement, peri-urban, rural, and tribal areas located in Northern, North-East, Eastern, and Southern regions of India from June 2020 to March 2022. Understanding the community dynamics and engaging people in the community is critically important in the process of establishing DDESS. We ascertained the barriers, challenges, and facilitators during the establishment of multiple DDESS sites across India. METHODS: This was a cross-sectional descriptive mixed-methods study. RESULTS: Multiple barriers and challenges encountered were reported in the process of community engagement (CE), such as geographical inaccessibility, language barriers, adverse weather, non-responsiveness due to perceived lack of individual benefit or financial gain, fear of contracting COVID-19, COVID-19 vaccine hesitancy, etc. Facilitators in the CE process were pre-existing links with the community, constitution of community advisory boards, community need assessment, concomitant delivery of outreach health services, and skill-building facilities. CONCLUSION: Most community barriers in the development of DDESS sites in resource-limited settings can be overcome through a multipronged approach, including effective community engagement by focusing on demonstrating trust at the local level, enlisting community mobilization and support, utilizing pre-existing community linkages, initiating community diagnosis, and meeting perceived community health needs.

Kidney disease burden in an Asian Indian population: Effect of the new 2021 serum creatinine CKD-EPI equation.

AIMS: CKD-EPI (chronic kidney disease-epidemiological) serum creatinine equation is widely accepted for calculating estimated glomerular filtration rate (eGFR). The effect of transitioning from the older 2009 to the newer race-independent 2021 CKD-EPI equation on the estimated kidney disease burden (eKDB) was studied in an Asian-Indian population. METHODS: The study included 1156 adults, the two equations were compared for agreement (Bland-Altman and Cohen's kappa) and concordance (Lin's correlation and test for proportions). RESULTS: The 2021 CKD-EPI increased the eGFR (positive-bias), independent of age-group, gender or presence of type 2 diabetes mellitus (T2DM) and hypertension (HTN). Thus, the eKDB was significantly decreased by 2021 CKD-EPI equation. The agreement was highest for the age-group 31-40 years (95.8 % versus 87.5 % for > 50 years). Besides, the eGFR category was shifted from G3 to G1 in 8.2 % (95 % CI: 6.8-9.9) individuals by 2021 CKD-EPI. The effect of transition on eKDB was greater in individuals > 50 years (7.4 %) or with HTN (6.3 %). CONCLUSION: In comparison to the old equation, the 2021 CKD-EPI equation increased the eGFR, lowering the eKDB in this Asian-Indian cohort. The degree of lowering was affected by age-group, and presence of T2DM /HTN, but independent of gender.

Estimation of tuberculosis incidence at subnational level using three methods to monitor progress towards ending TB in India, 2015-2020.

OBJECTIVES: We verified subnational (state/union territory (UT)/district) claims of achievements in reducing tuberculosis (TB) incidence in 2020 compared with 2015, in India. DESIGN: A community-based survey, analysis of programme data and anti-TB drug sales and utilisation data. SETTING: National TB Elimination Program and private TB treatment settings in 73 districts that had filed a claim to the Central TB Division of India for progress towards TB-free status. PARTICIPANTS: Each district was divided into survey units (SU) and one village/ward was randomly selected from each SU. All household members in the selected village were interviewed. Sputum from participants with a history of anti-TB therapy (ATT), those currently experiencing chest symptoms or on ATT were tested using Xpert/Rif/TrueNat. The survey continued until 30 Mycobacterium tuberculosis cases were identified in a district. OUTCOME MEASURES: We calculated a direct estimate of TB incidence based on incident cases identified in the survey. We calculated an under-reporting factor by matching these cases within the TB notification system. The TB notification adjusted for this factor was the estimate by the indirect method. We also calculated TB incidence from drug sale data in the private sector and drug utilisation data in the public sector. We compared the three estimates of TB incidence in 2020 with TB incidence in 2015. RESULTS: The estimated direct incidence ranged from 19 (Purba Medinipur, West Bengal) to 1457 (Jaintia Hills, Meghalaya) per 100 000 population. Indirect estimates of incidence ranged between 19 (Diu, Dadra and Nagar Haveli) and 788 (Dumka, Jharkhand) per 100 000 population. The incidence using drug sale data ranged from 19 per 100 000 population in Diu, Dadra and Nagar Haveli to 651 per 100 000 population in Centenary, Maharashtra. CONCLUSION: TB incidence in 1 state, 2 UTs and 35 districts had declined by at least 20% since 2015. Two districts in India were declared TB free in 2020.

Structured Lifestyle Modification Interventions Involving Frontline Health Workers for Population-Level Blood Pressure Reduction: Results of a Cluster Randomized Controlled Trial in India (DISHA Study).

Background Population-wide reduction in mean blood pressure is proposed as a key strategy for primary prevention of cardiovascular disease. We evaluated the effectiveness of a task-sharing strategy involving frontline health workers in the primary prevention of elevated blood pressure. Methods and Results We conducted DISHA (Diet and lifestyle Interventions for Hypertension Risk reduction through Anganwadi Workers and Accredited Social Health Activists) study, a cluster randomized controlled trial involving 12 villages each from 4 states in India. Frontline health workers delivered a custom-made and structured lifestyle modification intervention in the selected villages. A baseline survey was conducted in 23 and 24 clusters in the control (n=6663) and intervention (n=7150) groups, respectively. The baseline characteristics were similar between control and intervention clusters. In total 5616 participants from 23 clusters in the control area and 5699 participants from 24 clusters in the intervention area participated in a repeat cross-sectional survey conducted immediately after the intervention phase of 18-months. The mean (SD) systolic blood pressure increased from 125.7 (18.1) mm Hg to 126.1 (16.8) mm Hg in the control clusters, and it increased from 124.4 (17.8) mm Hg to 126.7 (17.5) mm Hg in the intervention clusters. The population average adjusted mean difference in difference in systolic blood pressure was 1.75 mm Hg (95% CI, -0.21 to 3.70). Conclusions Task-sharing interventions involving minimally trained nonphysician health workers are not effective in reducing population average blood pressure in India. Expanding the scope of task sharing and intensive training of health workers such as nurses, nutritionists, or health counselors in management of cardiovascular risk at the population level may be more effective in primary prevention of cardiovascular disease.

Safety and immunogenicity of a single dose, live-attenuated 'tetravalent dengue vaccine' in healthy Indian adults; a randomized, double-blind, placebo controlled phase I/II trial.

BACKGROUND: Dengue fever is the most prevalent mosquito-borne viral disease in the world, with 390 million dengue infections occurring every year. There is an unmet medical need to develop a safe, effective and affordable dengue vaccine against all four Dengue serotype viruses-DENV1, DENV-2, DENV-3 and DENV-4. Panacea Biotec Ltd (PBL) has developed a cell culture-derived, live-attenuated, lyophilized Tetravalent Dengue Vaccine (TDV). Here, in phase I/II study we assessed the safety and immunogenicity of single dose 'Dengue Tetravalent Vaccine' in healthy Indian adults. METHODS: In the study, 100 healthy adult volunteers aged 18-60 years were enrolled. The participants were allocated to TDV and placebo groups in 3:1 ratio, i.e. 75 participants to TDV group and 25 participants to the placebo group. Enrolled participants were administered a single dose of 0.5 ml of the test vaccine / placebo by subcutaneous route. Primary outcome for safety included all solicited AEs up to 21 days, unsolicited AEs up to 28 days and all AEs/serious adverse events (SAEs) till day 90 post-vaccination. For immunogenicity assessment the primary outcome was seroconversion & seropositivity rate by PRNT50 to all four serotype till 90 days. RESULTS: Overall, 100 subjects were vaccinated out of which 8 subjects (5 subjects in vaccine group and 3 subjects in placebo group) dropped out from the study. The most commonly reported solicited local AE was pain and most common solicited systemic AE was headache and fever. No SAE was reported during the study. There was no statistically significant difference between TDV and placebo groups in terms of AEs. Of the 92 subjects who completed all scheduled visits in the study, 59 (81.9%) achieved seroconversion for DENV-1, 56 (77.8%) for DENV-2; 59 (81.9%) for DENV-3 and 57 (79.2%) for DENV-4 in TDV group. The seroconversion rate in the TDV group was statistically significant (p < 0.001) compared to placebo.Clinical trial registration: CTRI/2017/02/007923.

Effect of internal migration on diabetes and metabolic abnormalities in India - The ICMR-INDIAB study.

AIMS: To assess the effect of migration (rural-to-urban and vice versa) on prevalence of diabetes and metabolic disorders in Asian Indians participating in the Indian Council of Medical Research-India Diabetes (ICMR-INDIAB) study. MATERIALS AND METHODS: The ICMR-INDIAB study is a national study on diabetes and associated cardiometabolic disorders in individuals aged ≥20 years from 28 states and 2 union territories of India. Individuals who moved to a different place from their place of birth and had resided in the new location for at least one year were considered as migrants. Anthropometric measurements, blood pressure estimation and a capillary oral glucose tolerance test were performed. RESULTS: Of the 113,043 participants, 66.4% were non-migrant rural dwellers, 19.4% non-migrant urban dwellers, 8.4% rural-urban migrants, 3.8% multiple migrants and 2.0% urban-rural migrants. Weighted prevalence of diabetes was highest in rural-urban migrants followed by urban dwellers, urban-rural migrants and rural dwellers [14.7%, 13.2%, 12.7% and 7.7% respectively (p < 0.001)]. Rural-urban migrants had highest prevalence of abdominal obesity (50.5%) compared to the other three groups. The risk for diabetes was 1.9 times higher in rural-urban migrants than among rural dwellers. Five risk factors [hypertension, abdominal and generalized obesity, physical inactivity and low fruit and vegetable intake] together explained 69.8% (partial population attributable risk) of diabetes among rural-urban migrants and 66.4% among non-migrant urban dwellers. CONCLUSIONS: Rural-to-urban migration is associated with increased risk of developing diabetes and other cardiometabolic abnormalities. Adoption of healthier lifestyle patterns among migrants could help prevent/delay onset of these abnormalities in this population.

The chunampet community health information management system: A health and demographic surveillance system from a rural South India.

BACKGROUND: Developed countries have strong health and demographic surveillance system (HDSS), whereas there is a dearth of such system in developing countries like India. India depends on national surveys and individual studies for public health information. At present All India Institute of Medical Sciences - New Delhi HDSS and Vadu HDSS are well established HDSS in India. MATERIALS AND METHODS: We developed a HDSS in a remote rural area of South India and named as Community Health Information Management System (CHIMS) This covered 20 villages around Rural Health Training Centre - Chunampet. We collected the family and demographic information from March 2018 to October 2018. Pregnancy, birth, under-five and mortality data were collected once in every 3 months with the help of interns, Medical Social Workers. Data collection done using CHIMS Guide and entered in EpiData software. EpiAnalysis, Quantum Geographic Information System, Dropbox were the other freely available software used in this program. RESULTS: CHIMS HDSS covered 14924 individuals belonging to 4486 households in the surrounding twenty villages. Population density was 213/km2. CHIMS consumed very limited resources in terms of workforce, materials, and transport. CHIMS database was used as a baseline database for many other studies. This CHIMS HDSS helped in many publications, postgraduate thesis dissertations and mainly attracted many extramural research funds from leading government Research Institutes from India. CONCLUSION: CHIMS proved to be a robust surveillance system in providing vital public health information about the community and attracted more extramural funds to the institute.

Association of kidney functions with a cascade of care for diabetes and hypertension in two geographically distinct Indian cohorts.

AIM: Type 2 diabetes (T2DM) and hypertension (HTN) are the main modifiable risk factors of chronic kidney disease (CKD), among the known traditional and non-traditional risk factors. METHODS: We determined the prevalence and care-cascade of these modifiable CKD-risk factors and their association with socioeconomic status in adjoining Lucknow and Puducherry cities of India. RESULTS: 439 participants reported no CKD were recruited. Serum analysis revealed an Estimated Glomerular Filtration Rate (eGFR) ≥ 90 ml/min/1.73 m2 in 60.36% of the population. Of them, 55.85% had HTN and/or T2DM as CKD-risk factors; however, less than half of this population was unaware of their CKD-risk status. Awareness and treatment were significantly higher in Puducherry and were associated with literacy, occupation, and residence place. Although the CKD-risk population was about two times higher in Puducherry than Lucknow, the populations with mild-low eGFR were comparable in the two regions. Moreover, in Lucknow, mild-low eGFR and low awareness were more prevalent among the younger participants (<30 years), relative to Puducherry. CONCLUSIONS: Despite a higher prevalence of CKD-risk factors in Puducherry, populations with mild-low eGFR were comparable to Lucknow. More heightened awareness and better care cascade for CKD-risk factors in Puducherry may prevent or delay eGFR reduction.

Distribution and Determinants of Chronic Kidney Disease of Unknown Etiology: A Brief Overview.

Globally, 33187000 DALYs and 956000 deaths are attributed to chronic kidney disease (CKD) every year. Diabetes and hypertension are the two most common causes of CKD. Another category of CKD without any known common causes, chronic kidney disease of unknown etiology (CKDu) is also increasingly reported from different regions of the world such as Central America, Sri Lanka, and India. They are predominately observed in agricultural communities where crops such as sugarcane and coconut are commonly cultivated. Young adults and males are at higher risk of developing CKDu. It mainly affects individuals belonging to lower socioeconomic status. Exposure to silica, arsenic, and fluoride might be associated with increased prevalence of CKDu. The role of heat stress in contributing to CKD through dehydration is unclear but cannot be ruled out. Mycotoxins such as aflatoxins and ochratoxins are also found to be associated with CKDu in some settings. Several studies have reported that CKDu has a significant positive association with pesticides used in agriculture such as HCH, Endosulfan, Alachlor, and Pendimethalin. There is also a possible role of infections by Hantavirus and Leptospirosis in acute febrile phase of CKDu. However, there is no conclusive evidence from studies conducted on CKDu regarding its causes and risk factors. Therefore, large-scale studies with better methodology need to be conducted to study the etiology and pathogenesis of CKDu in various settings.

Cardiovascular risk using WHO-ISH chart among Diabetes and Hypertensive patients in a remote rural area of South India.

INTRODUCTION: Cardiovascular diseases (CVDs) are major problems in India and many other developing and developed countries. As India is committed to provide universal health care for the population, there is a need to find out the prevalence and determinants of CVD risk among high-risk individuals (Diabetes and Hypertensive patients) in the remote rural area of India to deliver appropriate services, as they are considered as neglected population. METHODS: We screened high-risk individuals (Hypertension and Diabetes patients) for CVD risk using WHO/ISH chart, in a remote rural area of south India, covering ten villages surrounding the Rural Health Training Centre (RHTC), in August-September 2017. After line-listing the participants from the electronic database of RHTC, screening with questionnaire and biochemical tests was done at village level as the first step. Thereafter, the participants were invited to the hospital on a particular day where electrocardiography (ECG) and echocardiography (ECHO) were done with special consultation. RESULTS: Among the total of 303 individuals screened at the village level, 64 [21%(CI 17-25)] had a higher risk for CVD. 235 people attended the special consultation; among them, 212 underwent ECG and 88 underwent ECHO. Among those screened with ECHO, 18 had some cardiac pathologies. The relationship between CVD risk and other factors is shown in. After final adjustment, illiteracy [adjusted prevalence ratio (aPR) 1.8 (0.1-3.1)], anemia [aPR 1.8 (1-3.6)], and chronic renal diseases [aPR 1.8 (1.0-3.4)] were found to be associated with high risk for CVD among hypertension and diabetes groups. CONCLUSION: Cardiovascular disease risk assessment using WHO/ISH chart showed an association with poor education, anemia, and chronic kidney disease.

Prevalence and determinants of Alcohol use in a remote rural area in South India: A community-based cross-sectional study.

INTRODUCTION: Alcohol use is a major public health problem in India. We sought to study the use of alcohol and its risk factors in a rural area in South India. METHODS: This study was conducted in 20 villages surrounding a Rural Health Training Centre, located in South India. The study was done from March 2018 to October 2018 with the help of Medical Interns and Medical Social Workers using a pretested questionnaire. RESULTS: In a total population of 14,925, 11,995 individuals are in the age group of 15 years and above, among whom 1,005 were reported to be using alcohol. The prevalence of alcohol among 15 years and above is 8.4% (7.9-8.9) and the overall prevalence in the total population is 7% (6.3-7.1). Prevalence of alcohol use among males and females are 16% and 1%, respectively. The alcohol use is higher among those who prefer open defecation (adjusted Odds Ratio (aOR) 1.2 (1.0-1.4)), Kutcha house (aOR 1.7 (1.4-2.2)) or semi-pucca house (aOR 1.3 (1.121.6)), lower caste (Most Backward Castes (MBC) aOR 1.7 (1.2-2.2), Scheduled Castes (SC) aOR 2.1 (1.6-2.9)), male gender (aOR 41 (29-59)), Married 5.0 (3.7-6.8), or Separated 2.6 (1.5-4.4) and Diabetes 1.6 (1.1-2.3). CONCLUSION: Alcohol use in a remote rural area is high among socially deprived communities who live in kutcha and semi-pucca houses and belong to a lower caste. This needs serious public health interventions to improve their socioeconomic status.

Identifying and Addressing Factors Contributing to Pretreatment Loss to Follow-Up of Tuberculosis Patients Referred for Treatment from Medical Colleges in Pondicherry: An Implementation Research.

BACKGROUND: In India, there is no feedback regarding 34% of tuberculosis (TB) patients diagnosed and referred from medical colleges for treatment to peripheral health institutions (PHIs). OBJECTIVES: The aim of this study is to measure the effectiveness of the new intervention package, developed based on qualitative study in reducing pretreatment loss to follow-up (PTLFU) of all TB patients diagnosed and referred for treatment from medical colleges to PHIs. MATERIALS AND METHODS: An intervention was developed based on the findings of in depth-interviews conducted among different stakeholders such as TB patients who did/did not report, service providers working in four medical colleges in Pondicherry. Intervention consisting of phone calls, home visits, etc., was implemented for a period of 6 months. The baseline and endline proportion of TB patients for whom feedback received was determined from the available records (Revised National TB Control Program State Task Force Quarterly reports). RESULTS: Patient's ignorance, lack of faith in healthcare system, side effects and social stigma, unpleasant experience in hospitals, poor accessibility to directly observed treatment, short-course centers, drugs shortage, poor coordination between program and hospital staff were the risk factors for PTLFU. At baseline, the proportions of feedback received about TB patients referred for treatment from medical colleges to PHIs was 46%. After the initiation of interventions, it increased to 61% and 66% in the first and second quarters of 2017, respectively. CONCLUSION: Risk factors for PTLFU were multi-factorial related to both patient and health system. Simple, feasible interventions such as phone calls and home visits to TB patients were effective in reducing PTLFU.

Xpert negative means no TB: A mixed-methods study into early implementation of Xpert in Puducherry, India.

INTRODUCTION: Xpert MTB/RIF was implemented in 2016 as the initial diagnostic test for extrapulmonary, pediatric, and human immunodeficiency virus-associated tuberculosis (TB) and as an add-on test for sputum microscopy-negative patients under Revised National TB Control Programme, Puducherry, India. We intended to study the change in TB case notification rates (CNRs) after 2015 and explore the enablers and barriers for implementation of Xpert. MATERIALS AND METHODS: Sequential mixed-methods study, quantitative phase followed by a descriptive qualitative phase (key informant interviews with healthcare providers in the program). RESULTS: The TB (all forms) CNR increased in 2016 followed by a drop to 2015 levels in 2017. There was a reduction in patients notified as sputum-negative pulmonary TB and pediatric TB during 2016-2017. Healthcare providers used a negative Xpert result in ruling out TB among patients who would previously get diagnosed clinically. Perceived benefits of Xpert were efficiency, rapid results, and detecting resistance. Barriers included poor awareness among medical colleges and the private sector, difficulty in motivating sputum microscopy-negative patients for Xpert, and incompletely filled referral forms. CONCLUSION: Xpert-negative results should be interpreted cautiously after clinical assessment. Identified barriers should be addressed to ensure that all eligible undergo testing.

Burden of Pulmonary Tuberculosis among Tribal Population: A Cross-sectional Study in Tribal Areas of Maharashtra, India.

BACKGROUND: It is very important to identify and treat infectious pulmonary tuberculosis (PTB) patients at the earliest to save the life of the patients and to prevent the transmission of infectious agent to others. As per Global Tuberculosis (TB) Report 2017, an estimated 28 lakh new TB cases occur and 4.23 lakh people die due to TB annually. Due to the poor health services and lack of awareness, particularly vulnerable tribal groups are vulnerable or at risk to many diseases including TB. METHODOLOGY: A community-based cross-sectional study was conducted to determine the burden of pulmonary TB (PTB) among adult tribal population of Maharashtra. House-to-house visit was conducted to identify the presumptive TB cases and sputum microscopy and chest X-ray were done to confirm the diagnosis. RESULTS: In the survey, 6898 tribal adults were interviewed from 8 tribal clusters, and among them, 144 (2.1%) presumptive TB cases were identified. The most common symptom among the presumptive TB cases was cough for >2 weeks (93.1%). The prevalence of PTB in the study area estimated is 261per lakh tribal population per year. CONCLUSION: The current study shows that the estimated burden of PTB among tribal population is within the wide variation of prevalence reported from other studies in different tribal communities (133-3294 per lakh population) in India. The current study provides vital information on the burden of TB among the tribal population of Maharashtra which can be used as a baseline data for future epidemiological studies.

Is it feasible to carry out active case finding for tuberculosis in community-based settings?

INTRODUCTION AND OBJECTIVE: To achieve elimination of tuberculosis by 2025, identifying the remaining 25% of missed cases would play a major role. But there is paucity of evidence on this statement. This study aimed to assess feasibility of active case finding for tuberculosis in selected region of Puducherry. METHODS: Community based survey was conducted by groups of trained undergraduate medical students. During January 2018, all residents of study area were assessed for presence of presumptive symptoms related to tuberculosis. Presumptive cases of tuberculosis were identified as per the programme definition and the same were facilitated to undergo follow up necessary investigations to rule out tuberculosis through frequent domiciliary visits. The data collection was done using mobile based Epicollect open access app. Feasibility was assessed using indicators namely household coverage, proportions of presumptive cases identified and undergone follow up investigations, number needed to screen for presumptive and confirmed cases of tuberculosis and average time spent per person. RESULTS: Of the 2252 houses, 1746 were covered resulting in a response rate of 77.5% and included 6606 residents. Of the 55 presumptive cases identified (55/6606) 51 underwent investigations (51/55). Two new cases of tuberculosis were diagnosed in this survey. To identify one presumptive and confirmed case 120, 3303 people need to be screened respectively. CONCLUSION: Active case finding for tuberculosis is feasible provided the health system is able to invest adequate human resources and referral linkages to support peripheral centres.
