Psychosocial support groups for patients with multidrug-resistant tuberculosis: Five years of experience

"As a patient I do not belong to the clinic, I belong to the community": co-developing multi-level, person-centred tuberculosis stigma interventions in Cape Town, South Africa

Background

Anticipated, internal, and enacted stigma are major barriers to tuberculosis (TB) care engagement and directly impact patient well-being. Unfortunately, targeted stigma interventions are lacking. We aimed to co-develop a person-centred stigma intervention with TB-affected community members and health workers in South Africa.

Methods

Using a community-based participatory research approach, we conducted ten group discussions with people diagnosed with TB (past or present), caregivers, and health workers (total n = 87) in Khayelitsha, Cape Town. Group discussions were facilitated by TB survivors. Discussion guides explored experiences and drivers of stigma and used human-centred design principles to co-develop solutions. Recordings were transcribed, coded, thematically analysed, and then further interpreted using the socio-ecological model and behaviour change wheel framework.

Results

Intervention components across socio-ecological levels shared common functions linked to effective behaviour change, namely education, training, enablement, persuasion, modelling, and environmental restructuring. At the individual level, participants recommended counselling to improve TB knowledge and provide ongoing support. TB survivors can guide messaging to nurture stigma resilience by highlighting that TB can affect anyone and is curable, and provide lived experiences of TB to decrease internal and anticipated stigma. At the interpersonal level, support clubs and family-centred counselling were suggested to dispel TB-related myths and foster support. At the institutional level, health worker stigma reduction training informed by TB survivor perspectives was recommended to decrease enacted stigma. Participants discussed how integration of TB/HIV care services may exacerbate TB/HIV intersectional stigma and ideas for restructured service delivery models were suggested. At the community level, participants recommended awareness-raising events led by TB survivors, including TB information in school curricula. At the policy level, solutions focused on reducing the visibility generated by a TB diagnosis and resultant stigma in health facilities and shifting tasks to community health workers.

Conclusions

Decreasing TB stigma requires a multi-level approach. Co-developing a person-centred intervention with affected communities is feasible and generates stigma intervention components that are directed and implementable. Such community-led multi-level intervention components should be prioritised by TB programs, including integrated TB/HIV care services.

At the individual level, participants recommended counselling to improve TB knowledge and provide ongoing support. TB survivors can guide messaging to nurture stigma resilience by highlighting that TB can affect anyone and is curable, and provide lived experiences of TB to decrease internal stigma. At the interpersonal level, support clubs and family-centred counselling were suggested to dispel TB-related myths and foster support. At the institutional level, health worker stigma reduction training informed by TB survivor perspectives was recommended. Consideration of how integration of TB/HIV care services may exacerbate TB/HIV intersectional stigma and ideas for restructured service delivery models were suggested to decrease anticipated and enacted stigma. At the community level, participants recommended awareness-raising events led by TB survivors, including TB information in school curricula. At the policy level, solutions focused on reducing the visibility generated by a TB diagnosis and resultant stigma in health facilities and shifting tasks to community health workers.

Conclusions

Decreasing TB stigma requires a multi-level approach. Co-developing a person-centred intervention with affected communities is feasible and generates stigma intervention components that are directed and implementable. Such community-informed intervention components should be prioritised by TB programs, including integrated TB/HIV care services.

Canadian tuberculosis health care workers' perspectives on education and counselling for patients and family members who are born outside of Canada

Tuberculosis health care workers (TB HCWs) in low incidence settings have important perspectives on providing TB education and counselling to patients and family members born in other countries. The purpose of this qualitative study was to explore HCWs' perspectives on barriers and facilitators for capacity-building education and counselling with patients and family members born outside of Canada experiencing advanced infectious TB in Calgary, a city in western Canada. Data were collected through semi-structured interviews and field notes and thematically analysed. Twenty-four HCWs representing clerical staff, nurses, physicians, and allied health professionals employed in TB care were interviewed. HCWs described how multi-level barriers such as patients' fear of death, complex intra-family communication, information-laden appointments, and patients' precarious employment collided resulting in overwhelmed patients and reduced connection to family. Some HCWs were unsure how to discuss TB stigma with patients and family members. HCWs perceived that increased continuity of care and providing patients and family members with digestible amounts of information earlier were important steps towards better practice. HCWs identified that patients and families could benefit from preparation for initial appointments, increased continuity, and improved patient education materials. HCWs should also receive skills-training to facilitate individual and family counselling.

Enhancing the conversational agent with an emotional support system for mental health digital therapeutics

As psychological diseases become more prevalent and are identified as the leading cause of acquired disability, it is essential to assist people in improving their mental health. Digital therapeutics (DTx) has been widely studied to treat psychological diseases with the advantage of cost savings. Among the techniques of DTx, a conversational agent can interact with patients through natural language dialog and has become the most promising one. However, conversational agents' ability to accurately show emotional support (ES) limits their role in DTx solutions, especially in mental health support. One of the main reasons is that the prediction of emotional support systems does not extract effective information from historical dialog data and only depends on the data derived from one single-turn interaction with users. To address this issue, we propose a novel emotional support conversation agent called the STEF agent that generates more supportive responses based on a thorough view of past emotions. The proposed STEF agent consists of the emotional fusion mechanism and strategy tendency encoder. The emotional fusion mechanism focuses on capturing the subtle emotional changes throughout a conversation. The strategy tendency encoder aims at foreseeing strategy evolution through multi-source interactions and extracting latent strategy semantic embedding. Experimental results on the benchmark dataset ESConv demonstrate the effectiveness of the STEF agent compared with competitive baselines.

A scoping review of patient-centred tuberculosis care interventions: Gaps and opportunities

Tuberculosis (TB) is a leading cause of death globally. In 2015, the World Health Organization hailed patient-centred care as the first of three pillars in the End TB strategy. Few examples of how to deliver patient-centred care in TB programmes exist in practice; TB control efforts have historically prioritised health systems structures and processes, with little consideration for the experiences of people affected by TB. We aimed to describe how patient-centred care interventions have been implemented for TB, highlighting gaps and opportunities. We conducted a scoping review of the published peer-reviewed research literature and grey literature on patient-centred TB care interventions between January 2005 and March 2020. We found limited information on implementing patient-centred care for TB programmes (13 research articles, 7 project reports, and 19 conference abstracts). Patient-centred TB care was implemented primarily as a means to improve adherence, reduce loss to follow-up, and improve treatment outcomes. Interventions focused on education and information for people affected by TB, and psychosocial, and socioeconomic support. Few patient-centred TB care interventions focused on screening, diagnosis, or treatment initiation. Patient-centred TB care has to go beyond programmatic improvements and requires recognition of the diverse needs of people affected by TB to provide holistic care in all aspects of TB prevention, care, and treatment.

A study on tuberculosis disease disclosure patterns and its associated factors: Findings from a prospective observational study in Chennai

BACKGROUND

Disclosure of tuberculosis (TB) status by patients is a critical step in their treatment cascade of care. There is a lack of systematic assessment of TB disclosure patterns and its positive outcomes which happens dynamically over the disease period of individual patients with their family and wider social network relations.

METHODS

This prospective observational study was conducted in Chennai Corporation treatment units during 2019-2021. TB patients were recruited and followed-up from treatment initiation to completion. Information on disease disclosures made to different social members at different time points, and outcomes were collected and compared. Bivariate and multi variate analysis were used to identify the patients and contact characteristics predictive of TB disclosure status.

RESULTS

A total of 466 TB patients were followed-up, who listed a total of 4039 family, extra familial and social network contacts of them. Maximum disclosures were made with family members (93%) and half of the relatives, occupational contacts and friendship contacts (44-58%) were disclosed within 15 days of treatment initiation. Incremental disclosures made during the 150-180 days of treatment were highest among neighbourhood contacts (12%), and was significantly different between treatment initiation and completion period. Middle aged TB patients (31 years and 46-55 years) were found less likely to disclose (AOR 0.56 and 0.46 respectively; p<0.05) and illiterates were found more likely to disclose their TB status (AOR 3.91; p<0.05). Post the disclosure, family contacts have mostly provided resource support (44.90%) and two third of all disclosed contacts have provided emotional support for TB patients (>71%).

CONCLUSION

Findings explain that family level disclosures were predominant and disclosures made to extra familial network contacts significantly increased during the latter part of treatment. Emotional support was predominantly received by TB patients from all their contacts post disclosure. Findings could inform in developing interventions to facilitate disclosure of disease status in a beneficial way for TB patients.

Comorbidity of mental ill-health in tuberculosis patients under treatment in a rural province of South Africa: a cross-sectional survey

OBJECTIVES

Tuberculosis (TB) remains prevalent despite the availability of effective anti-TB medications, and accumulating evidence suggests a high rate of mental disorders in people with TB. This is because TB and psychiatric disorders share several risk factors, such as poverty, homelessness and substance use disorder. Moreover, psychiatric comorbidities in patients with TB are associated with poor treatment outcomes. This study explored the psychiatric comorbidity and clinical correlates in individuals receiving TB treatment.

DESIGN

A cross-sectional survey over 10 months.

SETTING

Two primary care clinics at King Sabata Dalindyebo district, Mthatha, Eastern Cape, South Africa.

PARTICIPANT

Patients receiving TB treatment in the two clinics.

INTERVENTION

The Mini-International Neuropsychiatric Interview was used to screen for psychiatric disorders.

PRIMARY AND SECONDARY OUTCOME MEASURES

Rates of mental disorders in patients with TB over a 10-month period. Variation in rates by sex, employment status and HIV comorbidity.

RESULTS

In a sample of 197 participants, most patients were men (62%) and screened positive for a mental disorder (82%) with anxiety (48%), depression (38%) and substance use disorders (43%) being the most common psychiatric conditions. On average, individuals had 4 (SD 2) mental disorders. Females had higher rates of depression (p=0.005) and non-adherence to TB treatment (p=0.003), and alcohol use disorder was more common in males (p<0.001) and in those non-adherent to TB treatment. Additionally, low education levels and unemployment were associated with depressive and anxiety disorders (p<0.05).

CONCLUSIONS

Mental disorders are common in patients with TB, and mental health services need to be integrated into the management of patients with TB. Factors linked to mental disorders in this cohort, such as low education, gender and unemployment, may be useful for compiling a risk profile to help identify those with TB who may require more intensive support for their mental health.

Patient- and Health-System-Related Barriers to Treatment Adherence for Patients with Drug-Resistant Tuberculosis in the Philippines: A Mixed-Methods Study

Purpose

In the Philippines, drug-resistant tuberculosis (DRTB) is a growing concern. Healthcare workers face challenges in retaining patients with DRTB in care. This study intends to understand their perspectives on the factors that influence patient treatment outcomes and to propose potential programmatic solutions for strengthening care services for the patients.

Methods

A mixed-methods study was conducted in the Philippines between December 2017 and March 2018 to understand the major barriers for healthcare workers to provide quality care to DRTB patients across the care continuum. In the quantitative phase, healthcare workers participated in an online survey; in the qualitative phase, in-depth interviews were conducted with a select number of the survey respondents to better understand their survey responses.

Results

272 healthcare workers participated in the survey, and of those, 11 were interviewed. Survey results identified economic constraints, patient perceptions of care, family-related concerns, and limited accessibility to healthcare services as the major patient-related barriers across the care continuum. Major health-system-related barriers were insufficient human resources, lack of financial and political support, and limited knowledge about DRTB by healthcare providers. Interviews revealed more elaborate, contextualized, and nuanced aspects of each of the major challenges. The elaborated patient-related barriers included expenses needed during treatment (e.g., transportation); fear of being stigmatized by family, community, or healthcare staff; worries about adverse drug reactions from medication; a lack of family support; and the location of patients' homes. The health-system-related barriers revealed through interviews included the limited capacities of facility staff to provide DRTB care due to insufficient human resources; the shortage of funds to support treatment completion (e.g., transportation allowance and food package for patients, service vehicles and mobile phone costs for outreach actions at the facility level); and discrimination by healthcare staff against patients with DRTB attributed to the staff's limited knowledge and experiences of treating the patients.

Conclusion

This study identified the main barriers for DRTB facility staff in the Philippines from the perspectives of providers. Further exploration of the barriers and best practices in facilities may be useful for improving DRTB care in the Philippines.

Analysing interventions designed to reduce tuberculosis-related stigma: A scoping review

Stigma is a critical barrier for TB care delivery; yet data on stigma reduction interventions is limited. This review maps the available literature on TB stigma reduction interventions, using the Health Stigma and Discrimination framework and an implementation analysis to identify research gaps and inform intervention design. Using search terms for TB and stigma, we systematically searched PubMed, EMBASE and Web of Science. Two independent reviewers screened all abstracts, full-texts, extracted data, conducted a quality assessment, and assessed implementation. Results were categorized by socio-ecological level, then sub-categorized by the stigma driver or manifestation targeted. After screening 1865 articles, we extracted data from nine. Three studies were implemented at the individual and interpersonal level using a combination of TB clubs and interpersonal support to target internal and anticipated stigma among persons with TB. Two studies were implemented at the interpersonal level using counselling or a video based informational tool delivered to households to reduce stigma drivers and manifestations. Three studies were implemented at the organizational level, targeting drivers of stigma among healthcare workers (HW) and enacted stigma among HWs. One study was implemented at the community level using an educational campaign for community members. Stakeholder consultation emphasized the importance of policy level interventions and education on the universality of risk to destigmatize TB. Review findings suggest that internal and anticipated TB stigma may be addressed effectively with interventions targeted towards individuals using counselling or support groups. In contrast, enacted TB stigma may be better addressed with information-based interventions implemented at the organizational or community level. Policy level interventions were absent but identified as critical by stakeholders. Implementation barriers included the lack of high-quality training and integration with mental health services. Three key gaps must be addressed in future research: consistent stigma definitions, standardized stigma measurement, and measurement of implementation outcomes.

Qualitative Identification of Intervention Preferences to Support Men's Engagement and Retention in TB Care in South Africa

Globally and in South African specifically, men account for 56% and 62% of all tuberculosis (TB) cases, respectively. Men are at increased risk of not accessing TB testing or treatment, and having poor treatment outcomes. Unfortunately, no interventions exist to address these issues. Toward the development of targeted, patient-centered TB care and support interventions, we used semistructured interviews to explored men's social network composition, TB testing behaviors, disclosure and treatment support, clinical experiences, and TB's influence on daily living. Data were analyzed using a thematic approach guided by the Network Individual Resource Model to identify mental and tangible resources influential and preferred during engagement in TB treatment. Men emphasized the desire for peer-to-peer support to navigate TB-related stigma and unhealthy masculinity norms. Men advocated for awareness events to educate communities about their challenges with TB. Men strongly suggested that interventions be delivered in familiar locations where men congregate. Since 2022, no TB treatment support interventions have included the preferred components or delivery modes described by men in our study. To improve men's TB-related health outcomes, the global TB community must identify and address men's unique challenges when designing interventions.

Interventions pathways to reduce tuberculosis-related stigma: a literature review and conceptual framework

BACKGROUND

Prevention of tuberculosis (TB)-related stigma is vital to achieving the World Health Organisation's End TB Strategy target of eliminating TB. However, the process and impact evaluation of interventions to reduce TB-stigma are limited. This literature review aimed to examine the quality, design, implementation challenges, and successes of TB-stigma intervention studies and create a novel conceptual framework of pathways to TB-stigma reduction.

METHOD

We searched relevant articles recorded in four scientific databases from 1999 to 2022, using pre-defined inclusion and exclusion criteria, supplemented by the snowball method and complementary grey literature searches. We assessed the quality of studies using the Crowe Critical Appraisal Tool, then reviewed study characteristics, data on stigma measurement tools used, and interventions implemented, and designed a conceptual framework to illustrate the pathways to TB-stigma reduction in the interventions identified.

RESULTS

Of 14,259 articles identified, eleven met inclusion criteria, of which three were high quality. TB-stigma reduction interventions consisted mainly of education and psychosocial support targeted predominantly toward three key populations: people with TB, healthcare workers, and the public. No psychosocial interventions for people with TB set TB-stigma reduction as their primary or co-primary aim. Eight studies on healthcare workers and the public reported a decrease in TB-stigma attributed to the interventions. Despite the benefits, the interventions were limited by a dearth of validated stigma measurement tools. Three of eight studies with quantitative stigma measurement questionnaires had not been previously validated among people with TB. No qualitative studies used previously validated methods or tools to qualitatively evaluate stigma. On the basis of these findings, we generated a conceptual framework that mapped the population targeted, interventions delivered, and their potential effects on reducing TB-stigma towards and experienced by people with TB and healthcare workers involved in TB care.

CONCLUSIONS

Interpretation of the limited evidence on interventions to reduce TB-stigma is hampered by the heterogeneity of stigma measurement tools, intervention design, and outcome measures. Our novel conceptual framework will support mapping of the pathways to impacts of TB-stigma reduction interventions.

Social Support and Depression Among Pulmonary Tuberculosis Patients in Anhui, China

Introduction

Pulmonary tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis affecting multiple tissues and organs. It is one of the leading causes of death and is a social disease in China. Increasing studies have revealed that the state of mental health and the social support are associated with the morbidity, mortality and community transmission of pulmonary TB patients. However, the previous global TB control and research strategy focused almost solely on the biomedical aspects. Therefore, in this study, we evaluated the level of depression and explored potential factors, including social support domains and socio-demographic characteristics in pulmonary TB patients to research the mental health state and the association between social support and pulmonary TB, ultimately implementing a multilevel intervene.

Methods

A cross-sectional study was carried out to describe the status of depression and social support, and explore related factors associated with depression among pulmonary TB patients in Anhui Province, China. Five counties (districts) in Anhui Province, China were selected by simple random sampling method. Patients diagnosed with pulmonary TB eligible to the study criteria were investigated. A structured questionnaire composed of information on socio-demographic characteristics, self-rating depression scale (SDS) and social support rating scale (SSRS) was used to collect the data.

Results

In this study, a total of 250 questionnaires were issued, and the effective questionnaires 237 were actually returned. Of the 237 patients with pulmonary TB, 71.3% of them were male and the mean age was 46.16 years (SD = 13.09). Depression symptoms were observed in 125 (52.7%) participants. Objective support (β = −0.192, P=0.002) and subjective support (β = −0.158, P = 0.015) had significantly negative effects on depression, while the effect of support utilization was not statistically significant. In contrast, being female (β = 0.119, P = 0.036) and patients with positive sputum smear results (β = 0.140, P = 0.014) were positively related to depression. Patients with monthly income between 500 and 999 were less likely to suffer from depression (β = −0.134, P = 0.024) than those who were poorer. Additionally, both education level and marital status were found to be correlated with social support and depression state (all P<0.05).

Discussion

In summary, the prevalence of depressive symptoms in pulmonary TB patients were high in Anhui Province, China. Low levels of social support can be an important predictor of depression symptoms. Therefore, screening for depression among pulmonary TB patients in the primary care setting is greatly warranted. Furthermore, psychological interventions should focus on providing available and adequate social support in order to improve mental health of them.

Tuberculosis and comorbidities: treatment challenges in patients with comorbid diabetes mellitus and depression

Tuberculosis is one of the leading causes of death worldwide, primarily affecting low- and middle income countries and individuals with limited-resources within fractured health care systems. Unfortunately, the COVID-19 pandemic has only served to aggravate the already existing diagnostic gap, decreasing the number of people who get diagnosed and thereby complete successful treatment. In addition to this, comorbidities act as an external component that when added to the TB management equation, renders it even more complex. Among the various comorbidities that interact with TB disease, diabetes mellitus and depression are two of the most prevalent among non-communicable diseases within the TB population and merits a thoughtful consideration when the healthcare system provides care for them. TB patients with diabetes mellitus (TB-DM) or depression both have an increased risk of mortality, relapse and recurrence. Both of these diseases when in presence of TB present a ‘vicious-circle-like’ mechanism, meaning that the effect of each disease can negatively add up, in a synergistic manner, complicating the patient’s health state. Among TB-DM patients, high glucose blood levels can decrease the effectiveness of anti-tuberculosis drugs; however, higher doses of anti-tuberculous drugs could potentially decrease the effects of DM drugs. Among the TB-depression patients, not only do we have the adherence to treatment problems, but depression itself can biologically shift the immunological profile responsible for TB containment, and the other way around, TB itself can alter the hormonal balance of several neurotransmitters responsible for depression. In this paper, we review these and other important aspects such as the pharmacological interactions found in the treatment of TB-DM and TB-depression patients and the implication on TB care and pharmacological considerations.

Depression among Tuberculosis patients and its association with treatment outcomes in district Srinagar

BACKGROUND

Tuberculosis (TB) is among the top 10 causes of death worldwide and there are estimated 10.4 million new (incident) patients, of which about one fourth are in India. There has been calls for rigorous investigations and interventions that may address other factors known to have effect on adherence of treatment like Depression but the amount of research into comorbidity is surprisingly low. The aim of the study was to assess magnitude and impact of depression among TB patients and determine the treatment outcomes of TB in District Srinagar.

METHODS

In this prospective study the adults with newly diagnosed TB were recruited within one month of initiating treatment and were followed upto the end of treatment. Data collection was done at three time-points: baseline, after 2 months and after 6 months of treatment initiation. The sample size of 200 was calculated using OpenEpi, V3 and identified 202 TB patients were interviewed in their local language and PHQ-9 scale was used to measure Depression.

RESULTS

The prevalence of Depression at baseline was 50.5% with CI (43.7%-57.3%). After two months of treatment the prevalence reduced to 9.4% with CI (5.9%-14.0%) and at the end of treatment to 2.5% with CI (0.91%-5.4%). Association between Depression in TB patients and treatment failure was found to be small to medium as revealed by Cramer's V test (0.29-0.59). Binary logistic regression estimated that at baseline TB patients with Depression were at 4.46 times at more risk of treatment failure than patients without Depression and those patients who continued Depression even after intensive phase were 34.5 times at higher risk.

CONCLUSION

Our findings indicate Depression is associated with poor treatment outcome in these patients, despite TB treatment. TB treatment strategies should consider screening and managing the psychologically distressed individuals among TB patients.

Pharmacological or non-pharmacological interventions for treatment of common mental disorders associated with Tuberculosis: A systematic review

We aimed to review the literature on interventions for treating Common Mental Disorders (CMD) in people with Tuberculosis (TB). We followed PRISMA guidelines and the protocol was registered at PROSPERO. The electronic databases (PsycInfo, CINAHL, Medline, Google Scholar, Embase) were searched from 1982 to 2020. 349 relevant records were screened, with 26 examined at full text. 13 studies were included totalling 4326 participants. A meta-analysis was not possible due to nature of data, thus descriptive synthesis was conducted. Eleven studies evaluated psychosocial interventions, which significantly improved adherence or cure rates from TB, anxiety and depression. The elements of effective psychosocial interventions included; combating stigma, socioeconomic disadvantage, managing associated guilt and fear of contagion, and explanatory models of illness in local population. Two articles evaluated pharmacological interventions (antidepressants and Vitamin D). This is the first systematic review of interventions to treat CMD in TB. The studies were mostly low quality and mental health outcomes were not adequately described. However, this review suggests that it is feasible to develop and test interventions for improving mental health outcomes and enhancing treatment adherence in TB.

Turning threats into opportunities: how to implement and advance quality TB services for people with HIV during the COVID-19 pandemic and beyond

INTRODUCTION

Until COVID-19, tuberculosis (TB) was the leading infectious disease killer globally, disproportionally affecting people with HIV. The COVID-19 pandemic is threatening the gains made in the fight against both diseases.

DISCUSSION

Although crucial guidance has been released on how to maintain TB and HIV services during the pandemic, it is acknowledged that what was considered normal service pre-pandemic needs to improve to ensure that we rebuild person-centred, inclusive and quality healthcare services. The threat that the pandemic may reverse gains in the response to TB and HIV may be turned into an opportunity by pivoting to using proven differentiated service delivery approaches and innovative technologies that can be used to maintain care during the pandemic and accelerate improved service delivery in the long term. Models of care should be convenient, supportive and sufficiently differentiated to avoid burdensome clinic visits for medication pick-ups or directly observed treatments. Additionally, the pandemic has highlighted the chronic and short-sighted lack of investment in health systems and the need to prioritize research and development to close the gaps in TB diagnosis, treatment and prevention, especially for children and people with HIV. Most importantly, TB-affected communities and civil society must be supported to lead the planning, implementation and monitoring of TB and HIV services, especially in the time of COVID-19 where services have been disrupted, and to report on legal, policy and gender-related barriers to access experienced by affected people. This will help to ensure that TB services are held accountable by affected communities for delivering equitable access to quality, affordable and non-discriminatory services during and beyond the pandemic.

CONCLUSIONS

Successfully reaching the related targets of ending TB and AIDS as public health threats by 2030 requires rebuilding of stronger, more inclusive health systems by advancing equitable access to quality TB services, including for people with HIV, both during and after the COVID-19 pandemic. Moreover, services must be rights-based, community-led and community-based, to ensure that no one is left behind.

Impacts of social support on the treatment outcomes of drug-resistant tuberculosis: a systematic review and meta-analysis

OBJECTIVE

To assess the effectiveness of social support on treatment success promotion or lost to follow-up (LTFU) reduction for patients with drug-resistant tuberculosis (DR-TB).

DESIGN

We searched Pubmed, Web of Science, Embase, Scopus and Medline databases until 18 June 2020 for interventional or mixed-method studies which reported social support and treatment outcomes of DR-TB patients. Two independent reviewers extracted data and disagreements were resolved by consensus with a third reviewer. Random-effects meta-analysis was performed to calculate the OR and 95% CI for the effects of social support on the improvement of treatment outcomes and the heterogeneity and risk of bias were assessed.

SETTING

Low-income and middle-income countries.

PARTICIPANTS

DR-TB patients.

OUTCOMES

Treatment success is defined as the combination of the cured and treatment completion, and LTFU is measured as treatment being interrupted for two consecutive months or more.

RESULTS

Among 173 articles selected for full-text review, 162 were excluded through independent review (kappa=0.87) and 10 studies enrolling 1621 DR-TB patients in eight countries were included for qualitative analysis. In these studies, the most frequently introduced social support was material support (10 studies), followed by informational (eight studies), emotional (seven studies) and companionship support (four studies). Seven studies that reported treatment outcomes in both intervention arm and control arm are qualified for meta-analysis. An encouraging improvement on treatment success rate (OR: 2.58; 95% CI: 1.80 to 3.69) was found when material support was integrated into social support packages and no heterogeneity was observed (I1 of 0%, Q test p=0.72). Reduction on LTFU rate (OR: 0.17; 95% CI: 0.05 to 0.55) was also noted when material support was available but substantial heterogeneity was found (I² of 80%, Q test p=0.002).

CONCLUSION

Material support appeared feasible and effective to improve treatment success for DR-TB patients combined with other social support interventions.

Social trust and health seeking behaviours: A longitudinal study of a community-based active tuberculosis case finding program in the Philippines

Introduction

Social trust is an important driver of health seeking behaviours and plays a particularly important role for diseases that have a high degree of stigma associated with them, such as tuberculosis (TB). Individuals experiencing poverty also face additional social and financial barriers in accessing care for TB. We examined an active case finding (ACF) initiative embedded in a program targeting those living in poverty (Transform) implemented by International Care Ministries (ICM), a Philippine-based non-governmental organization (NGO), and analyzed how different forms of social trust may affect the initial uptake of ACF.

Methods

Program monitoring data and a cross-sectional survey conducted at the beginning of Transform included six dimensions of social trust: satisfaction with family life, satisfaction with friendships, and level of trust in relatives, neighbours, pastor or religious leader, and local government officials. Amongst individuals suspected of having TB who received referrals post-screening, multilevel modelling examined the effects of social trust on rural health unit (RHU) attendance.

Results

Among the subset of 3350 individuals who received TB screening in 51 communities, 889 (26.5%) were symptom positive and required referral to the RHU, but only 24.1% of those who received referrals successfully attended the RHU. Multilevel regression analysis showed that for each unit increase on the Likert scale in baseline level of family satisfaction and level of trust in relatives, the odds of attending an RHU was 1.03 times (95% CI: 0.99, 1.07) and 1.06 times greater (95% CI: 1.00, 1.11), respectively, independent of other factors.

Conclusion

These results suggest that social trust in family members could play a valuable role in addressing stigma and rejection, both cited as barriers to higher screening rates. It is recommended that ACF programs that target TB, or other diseases that are stigmatized, prioritize trust-building as an important component of their intervention.

•

Role of social trust on health clinic attendance among extreme poor examined.

•

Effect of five relationship types in supporting tuberculosis testing explored.

•

Trust in family relationships predicted greater health clinic testing.

•

Health interventions for stigmatized diseases should prioritize trust-building.

Depression and delayed tuberculosis treatment initiation among newly diagnosed patients in Botswana

Comorbidity of tuberculosis (TB) and depression may lead to delayed TB treatment initiation. A cross-sectional study was conducted between January and December 2019 to examine the association between depression and delayed TB treatment initiation among newly diagnosed TB patients in Botswana. We used the Patient Health Questionnaire-9 and the ZUNG self-rating anxiety scale to assess depressive and anxiety symptoms, respectively. Delayed TB treatment was defined as experiencing common TB symptoms for more than 2 months before treatment initiation. We used Poisson regression models with robust variance to assess the association between covariates and delayed treatment initiation. Majority of the enrolled 180 study participants were males (n =116, 64.4%). Overall, 99 (55%) were co-infected with HIV; depression and anxiety symptoms were reported by 47.2% and 38.5% of the participants respectively. The prevalence of delayed TB treatment was 42.6% and 18.8% among participants who indicated symptoms of depression and among participants without depression respectively. After adjusting for age, HIV status, gender and anxiety symptoms, depression was still associated with delayed TB treatment (adjusted prevalence ratio [aPR] = 2.09; 95% CI = 1.23-3.57). Integrating management of depressive symptoms during TB treatment may help in improving overall TB treatment outcomes.

The necessity of psychological interventions to improve compliance with Tuberculosis treatment and reduce psychological distress

One of the major obstacles in treating TB is the patient's nonadherence to the treatment regimen resulting in prolonged disease transmission and development of resistance to anti-TB drugs. An individual's mental health affects his/her adaptation to the disease. Mental health issues and TB both are inextricably connected and research into this area will provide an opportunity to develop a more holistic model of TB treatment and prevention.

Aims:

The aim of this study is to investigate the prevalence of mental health issues in patients with TB and its influence on individual perception of well-being with an emphasis on psychopathology as a major obstacle to treatment adherence. Research into this area will provide an opportunity to develop a more holistic model of TB treatment and prevention.

Settings and Design:

Primary data were collected with the help of ASHA workers, and primary survey-based study was designed.

Methods and Material:

A total of 249 diagnosed Tuberculosis cases were included in the study. A digitalized version of the PGIHQN-1 questionnaire was made and used to separate the psychiatric population from the normal group. Asha workers were trained to use the digital version on tablets.

Statistical Analysis Used:

Using Microsoft Excel, Graphic Tables, and corelation were done using SPSS Statistics.

Results:

Mental health issues were found in diagnosed TB cases, which required further evaluations. Along with mental health issues, limited resources, gender, limited education, lack of proper knowledge about the disease, having responsibilities (Marital status), locality were found to be the important factors that complicate TB outcomes, hence should be taken into consideration while imparting psychological interventions.

Conclusion:

Mental health issues complicate TB outcome and hence need to be properly addressed, and thorough psychoeducation, psychological first aid (listen, protect, connect, model& teach), and timely intervention in the form of proper diagnosis and specific treatment and rehabilitation are needed.

Management of multidrug-resistant tuberculosis: main recommendations of the Brazilian guidelines

Over the years, various recommendations have been made in pursuit of controlling resistance to antituberculosis drugs, especially multidrug resistance, in Brazil. Given the importance of standardizing those recommendations, the aim of this study was to describe the main recommendations of the Brazilian guidelines, primarily those related to the treatment and follow-up of cases of tuberculosis. From August through October of 2018, a document search was conducted via the websites of the Brazilian National Ministry of Health, the Brazilian National Tuberculosis Control Program, the JBP, and the Official Gazette of the Federal Republic of Brazil. Data were collected systematically by using a protocol designed specifically for this study. Documents published between 2004 and 2018 were selected. It was possible to understand and trace the history of the measures for the control of multidrug-resistant tuberculosis in Brazil from 2004, when the first documents related to the disease were published, up to 2018, when the second edition of the Brazilian National Guidelines for the Control of Tuberculosis was published. The contents of the documents were analyzed and grouped by case definition, diagnostic criteria, treatment, use of directly observed treatment; mechanisms of social protection for patients; data tools; and organization of care. This analysis allowed us to understand the efforts towards standardizing some measures in Brazil, not only identifying advances in the alignment with international prerogatives (case definition, incorporation of diagnostic technology, and treatment regimens) but also underscoring the need for greater clarity regarding the mechanisms of social protection and the organization of the care provided via the Brazilian health care system.

Closing gaps in the tuberculosis care cascade: an action-oriented research agenda

The care cascade-which evaluates outcomes across stages of patient engagement in a health system-is an important framework for assessing quality of tuberculosis (TB) care. In recent years, there has been progress in measuring care cascades in high TB burden countries; however, there are still shortcomings in our knowledge of how to reduce poor patient outcomes. In this paper, we outline a research agenda for understanding why patients fall through the cracks in the care cascade. The pathway for evidence generation will require new systematic reviews, observational cohort studies, intervention development and testing, and continuous quality improvement initiatives embedded within national TB programs. Certain gaps, such as pretreatment loss to follow-up and post-treatment disease recurrence, should be a priority given a relative paucity of high-quality research to understand and address poor outcomes. Research on interventions to reduce death and loss to follow-up during treatment should move beyond a focus on monitoring (or observation) strategies, to address patient needs including psychosocial and nutritional support. While key research questions vary for each gap, some patient populations may experience disparities across multiple stages of care and should be a priority for research, including men, individuals with a prior treatment history, and individuals with drug-resistant TB. Closing gaps in the care cascade will require investments in a bold and innovative action-oriented research agenda.

Comorbidities between tuberculosis and common mental disorders: a scoping review of epidemiological patterns and person-centred care interventions from low-to-middle income and BRICS countries

Background

There is increasing evidence that the substantial global burden of disease for tuberculosis unfolds in concert with dimensions of common mental disorders. Person-centred care holds much promise to ameliorate these comorbidities in low-to-middle income countries (LMICs) and emerging economies. Towards this end, this paper aims to review 1) the nature and extent of tuberculosis and common mental disorder comorbidity and 2) person-centred tuberculosis care in low-to-middle income countries and emerging economies.

Main text

A scoping review of 100 articles was conducted of English-language studies published from 2000 to 2019 in peer-reviewed and grey literature, using established guidelines, for each of the study objectives. Four broad tuberculosis/mental disorder comorbidities were described in the literature, namely alcohol use and tuberculosis, depression and tuberculosis, anxiety and tuberculosis, and general mental health and tuberculosis. Rates of comorbidity varied widely across countries for depression, anxiety, alcohol use and general mental health. Alcohol use and tuberculosis were significantly related, especially in the context of poverty. The initial tuberculosis diagnostic episode had substantial socio-psychological effects on service users. While men tended to report higher rates of alcohol use and treatment default, women in general had worse mental health outcomes. Older age and a history of mental illness were also associated with pronounced tuberculosis and mental disorder comorbidity. Person-centred tuberculosis care interventions were almost absent, with only one study from Nepal identified.

Conclusions

There is an emerging body of evidence describing the nature and extent of tuberculosis and mental disorders comorbidity in low-to-middle income countries. Despite the potential of person-centred interventions, evidence is limited. This review highlights a pronounced need to address psychosocial comorbidities with tuberculosis in LMICs, where models of person-centred tuberculosis care in routine care platforms may yield promising outcomes.

Development of a risk score for prediction of poor treatment outcomes among patients with multidrug-resistant tuberculosis

Background

Treatment outcomes among patients treated for multidrug-resistant tuberculosis (MDR-TB) are often sub-optimal. Therefore, the early prediction of poor treatment outcomes may be useful in patient care, especially for clinicians when they have the ability to make treatment decisions or offer counselling or additional support to patients. The aim of this study was to develop a simple clinical risk score to predict poor treatment outcomes in patients with MDR-TB, using routinely collected data from two large countries in geographically distinct regions.

Methods

We used MDR-TB data collected from Hunan Chest Hospital, China and Gondar University Hospital, Ethiopia. The data were divided into derivation (n = 343; 60%) and validation groups (n = 227; 40%). A poor treatment outcome was defined as treatment failure, lost to follow up or death. A risk score for poor treatment outcomes was derived using a Cox proportional hazard model in the derivation group. The model was then validated in the validation group.

Results

The overall rate of poor treatment outcome was 39.5% (n = 225); 37.9% (n = 86) in the derivation group and 40.5% (n = 139) in the validation group. Three variables were identified as predictors of poor treatment outcomes, and each was assigned a number of points proportional to its regression coefficient. These predictors and their points were: 1) history of taking second-line TB treatment (2 points), 2) resistance to any fluoroquinolones (3 points), and 3) smear did not convert from positive to negative at two months (4 points). We summed these points to calculate the risk score for each patient; three risk groups were defined: low risk (0 to 2 points), medium risk (3 to 5 points), and high risk (6 to 9 points). In the derivation group, poor treatment outcomes were reported for these three groups as 14%, 27%, and 71%, respectively. The area under the receiver operating characteristic curve for the point system in the derivation group was 0.69 (95% CI 0.60 to 0.77) and was similar to that in the validation group (0.67; 95% CI 0.56 to 0.78; p = 0.82).

Conclusion

History of second-line TB treatment, resistance to any fluoroquinolones, and smear non-conversion at two months can be used to estimate the risk of poor treatment outcome in patients with MDR-TB with a moderate degree of accuracy (AUROC = 0.69).

Quality of drug-resistant tuberculosis care: Gaps and solutions

Drug-resistant forms of tuberculosis (DR-TB) are a significant cause of global morbidity and mortality and the treatment of DR-TB is characterized by long and toxic regimens that result in low rates of cure. There are few formal studies documenting the quality of DR-TB treatment services provided globally, but the limited data that do exist show there is a quality crisis in the field. This paper reviews current issues impacting quality of care in DR-TB, including within the areas of patient-centeredness, safety, effectiveness and equity. Specific issues affecting DR-TB quality of care include: 1) the use of regimens with limited efficacy, significant toxicity, and high pill burden; 2) standardized treatment without drug susceptibility testing; 3) non-quality assured medications and drug stock outs; 4) lack of access to newer and repurposed drugs; 5) high rates of adverse events coupled with minimal monitoring and management; 6) care provided by multiple providers in the private sector; 7) depression, anxiety, and stress; and 8) stigma and discrimination. The paper discusses potential ways to improve quality in each of these areas and concludes that many of these issues arise from the traditional "public health approach" to TB and will only transformed when a human-rights based approach is put into practice.

The interplay between depression and tuberculosis

Depression is a major mental health condition and is expected be the most debilitating and widespread health disorder by 2030. Tuberculosis (TB) is also a leading cause of morbidity and mortality worldwide and interestingly, is a common comorbidity of depression. As such, much attention has been paid to the association between these 2 pathologies. Based on clinical reports, the association between TB and depression seems to be bidirectional, with a substantial overlap in symptoms between the 2 conditions. TB infection or reactivation may precipitate depression, likely as a consequence of the host's inflammatory response and/or dysregulation of the hypothalamic-pituitary-adrenal axis. Nevertheless, few studies have considered whether patients with depression are at a higher risk for TB. In this review, we discuss the hypotheses on the association between depression and TB, highlighting the immuno-inflammatory response and lipid metabolism as potential mechanisms. Improving our understanding of the interplay between these 2 disorders should help guide TB clinical care and prevention both in patients with comorbid depression and in the general population.

More Than Malnutrition: A Review of the Relationship Between Food Insecurity and Tuberculosis

Despite a significant reduction in tuberculosis (TB) mortality over the past decade, TB remains a leading cause of death worldwide. Food insecurity-through pathways such as malnutrition, mental health impact, and high-risk health behaviors-affects the risk of TB disease, treatment failure, and mortality. We searched the literature for studies reporting on the links between food insecurity and TB. In contrast to the well-documented interactions between food insecurity and HIV/AIDS, we found that the association between food insecurity and TB remains largely understudied-this is especially true with regard to non-nutritional correlations. Mental health and behavioral linkages between TB and food insecurity deserve further attention. An improved understanding of the pathways through which food insecurity impacts TB is crucial to inform evidence-based integration of interventions such as psychological counseling, psychiatric care, harm reduction programs, and efforts to address social determinants of disease within current TB programs.

Depression and anxiety in patients with multidrug-resistant tuberculosis in Nepal: an observational study

Setting

Multidrug-resistant tuberculosis (MDR-TB) patients in the national TB treatment programme of Nepal.

Objective

To estimate the prevalence of depression and anxiety in people receiving treatment for MDR-TB, identify potential risk factors for depression and anxiety and determine temporal changes in their severity during treatment.

Design

An observational study using a screening tool, the Hopkins Symptom Checklist (HSCL-25) for depression and anxiety, administered monthly to a group of 135 patients in Nepal. Logistic and multilevel linear regression models were used to identify any patient characteristics associated with depression and anxiety.

Results

Most of the 135 patients were male (76%) and living with their families (68%). The period prevalences of depression and anxiety were respectively 22.2% and 15.6%. Patients reporting physical side effects of MDR-TB treatment had a higher depression score on HSCL by 2.63 points (95%CI 0.77-4.48) and a 1.59 point higher anxiety score (95%CI 0.45-2.73) than those who did not report any side effects. Being single was associated with having anxiety (aOR 0.2, 95%CI 0.03-1.0).

Conclusion

Given the high rates of depression observed among MDR-TB patients, national TB treatment programmes should ensure their patients are routinely screened for depression and anxiety, and effective treatment offered.

[Control and management strategies in multidrug-resistant tuberculosis: literature reviewEstrategias de control y atención de la tuberculosis multirresistente: una revisión de la literatura]

OBJECTIVE

To identify control and patient management strategies for multidrug-resistant tuberculosis (MDR-TB).

METHODS

An integrative review of the literature was performed through research in three health databases (LILACS, PubMed and CINAHL) and one multidisciplinary database (Scopus). Original articles published in English, Spanish or Portuguese, from 2006 to 2016, describing strategies to implement MDR-TB patient care, were included. The information collected was organized according to the strategies identified by the investigators, which were grouped into theme categories.

RESULTS

Based on a sample of 13 articles, four categories were identified: a) DOTS-plus: reorganization of health services, improvement of local structures, standardization of professional protocols and behaviors, provision of directly observed treatment; b) service decentralization: bringing health professionals closer to patients, especially in areas with high disease burden; c) use of communication tools: software and telephone calls that allowed consultations with specialists and/or optimization of care within multiprofessional teams; d) social protection of patients: establishment of mechanisms to provide emotional, social and/or economic support to patients under treatment, strengthening adherence to drug therapy.

CONCLUSIONS

Several strategies were identified beyond pharmacological measures, supporting the idea that the control of MDR-TB requires mechanisms that allow comprehensive care, consistent with the peculiarities and potentialities of the different scenarios where the disease occurs.

Interventions to improve retention-in-care and treatment adherence among patients with drug-resistant tuberculosis: a systematic review

The global loss to follow-up (LTFU) rate among drug-resistant tuberculosis (DR-TB) patients remains high at 15%. We conducted a systematic review to explore interventions to reduce LTFU during DR-TB treatment.We searched for studies published between January 2000 and December 2017 that provided any form of psychosocial or material support for patients with DR-TB. We estimated point estimates and 95% confidence intervals of the proportion LTFU. We performed subgroup analyses and pooled estimates using an exact binomial likelihood approach.We included 35 DR-TB cohorts from 25 studies, with a pooled proportion LTFU of 17 (12-23)%. Cohorts that received any form of psychosocial or material support had lower LTFU rates than those that received standard care. Psychosocial support throughout treatment, via counselling sessions or home visits, was associated with lower LTFU rates compared to when support was provided through a limited number of visits or not at all.Our review suggests that psychosocial support should be provided throughout DR-TB treatment in order to reduce treatment LTFU. Future studies should explore the potential of providing self-administered therapy complemented with psychosocial support during the continuation phase.

To End TB, First-Ever High-Level Meeting on Tuberculosis Must Address Stigma

World leaders gather to consolidate their commitment to ending tuberculosis (TB). Vital to the success of renewed efforts is an overdue recognition of the pervasive and pernicious influence of TB stigma. TB stigma is sustained in structures, policies, traditions, and norms. Innovative modifications to infection control, drug dispensing, and surveillance practices are required to increase demand for TB screening and effective therapeutic alliances among those diagnosed. The authors argue that reducing TB stigma requires a scientific and inclusive process, with prominent roles for TB survivors and a willingness to integrate and learn from other stigmatized conditions.

Implementation of a psychosocial support package for people receiving treatment for multidrug-resistant tuberculosis in Nepal: A feasibility and acceptability study

Background and objectives

People receiving treatment for multidrug-resistant tuberculosis (MDR-TB) have high rates of depression. Psychosocial support in general, and treatments for depression in particular, form an important but neglected area of patient-centred care, and a key pillar in the global End TB strategy. We assessed the feasibility and acceptability of a psychosocial support package for people receiving treatment for MDR-TB in Nepal.

Methods

This feasibility study used a mixed quantitative and qualitative approach. We implemented the intervention package in two National Tuberculosis Programme (NTP) MDR-TB treatment centres and 8 sub-centres. We screened patients monthly for depression and anxiety (cut-off ≥24 and ≥17 respectively on the Hopkins Symptom Checklist) and also for low social support (cut-off ≤3 on the Multidimensional Scale of Perceived Social Support). Those who screened positive on either screening tool received the Healthy Activity Program (HAP), which uses brief counselling based on behavioural activation theory. Other aspects of the psychosocial package were information/education materials and group interactions with other patients.

Results

We screened 135 patients, of whom 12 (9%) received HAP counselling, 115 (85%) received information materials, 80 (59%) received an education session and 49 (36%) received at least one group session. Eight group sessions were conducted in total. All aspects of the intervention package were acceptable to patients, including the screening, information, group work and counselling. Patients particularly valued having someone to talk to about their concerns and worries. We were able to successfully train individuals with no experience of psychological counselling to deliver HAP.

Conclusion

This psychosocial support package is acceptable to patients. The information materials we developed are feasible to deliver in the current NTP. However, the structured psychological counselling (HAP), is not feasible in the current NTP due to time constraints. This requires additional investment of counsellors in TB clinics.

Mental health disorders, social stressors, and health-related quality of life in patients with multidrug-resistant tuberculosis: A systematic review and meta-analysis

BACKGROUND

Mental health disorders, social stress, and poor health-related quality of life are commonly reported among people with tuberculosis (TB). We conducted a systematic review and meta-analysis to quantify mental health disorders, social stressors, and health-related quality of life in patients with multidrug-resistant tuberculosis (MDR-TB).

METHODS

We searched PubMed, SCOPUS, ProQuest, Web of Science, and PsycINFO databases for studies that reported data on mental health disorders, social stressors, and health-related quality of life among MDR-TB patients. Hand-searching the reference lists of included studies was also performed. Studies were selected according to pre-defined selection criteria and data were extracted by two authors. Pooled prevalence and weighted mean difference estimates were performed using random-effects meta-analysis. Heterogeneity was explored using meta-regression, and subgroup analyses were performed.

RESULTS

We included a total of 40 studies that were conducted in 20 countries. Depression, anxiety, and psychosis were the most common mental health disorders reported in the studies. The overall pooled prevalence was 25% (95% confidence interval (CI): 14, 39) for depression, 24% (95% CI: 2, 57) for anxiety, and 10% (95% CI: 7, 14) for psychosis. There was substantial heterogeneity in the estimates. The stratified analysis showed that the prevalence of psychosis was 4% (95% CI: 0, 22) before MDR-TB treatment commencement, and 9% (95% CI: 5, 13) after MDR-TB treatment commencement. The most common social stressors reported were stigma, discrimination, isolation, and a lack of social support. Health-related quality of life was significantly lower among MDR-TB patients when compared to drug-susceptible TB patients (Q = 9.88, p = 0.01, I² = 80%).

CONCLUSIONS

This review found that mental health and social functioning are compromised in a significant proportion of MDR-TB patients, a finding confirmed by the poor health-related quality of life reported. Thus, there is a substantial need for integrating mental health services, social protection and social support into the clinical and programmatic management of MDR-TB.

Addressing the tuberculosis-depression syndemic to end the tuberculosis epidemic

Tuberculosis (TB) and depression act synergistically via social, behavioral, and biological mechanisms to magnify the burden of disease. Clinical depression is a common, under-recognized, yet treatable condition that, if comorbid with TB, is associated with increased morbidity, mortality, community TB transmission, and drug resistance. Depression may increase risk of TB reactivation, contribute to disease progression, and/or inhibit the physiological response to anti-tuberculosis treatment because of poverty, undernutrition, immunosuppression, and/or negative coping behaviors, including substance abuse. Tuberculous infection and/or disease reactivation may precipitate depression as a result of the inflammatory response and/or dysregulation of the hypothalamic-pituitary-adrenal axis. Clinical depression may also be triggered by TB-related stigma, exacerbating other underlying social vulnerabilities, and/or may be attributed to the side effects of anti-tuberculosis treatment. Depression may negatively impact health behaviors such as diet, health care seeking, medication adherence, and/or treatment completion, posing a significant challenge for global TB elimination. As several of the core symptoms of TB and depression overlap, depression often goes unrecognized in individuals with active TB, or is dismissed as a normative reaction to situational stress. We used evidence to reframe TB and depression comorbidity as the 'TB-depression syndemic', and identified critical research gaps to further elucidate the underlying mechanisms. The World Health Organization's Global End TB Strategy calls for integrated patient-centered care and prevention linked to social protection and innovative research. It will require multidisciplinary approaches that consider conditions such as TB and depression together, rather than as separate problems and diseases, to end the global TB epidemic.

Training social workers to enhance patient-centered care for drug-resistant TB-HIV in South Africa

KwaZulu-Natal, South Africa, is the epicenter of an epidemic of drug-resistant tuberculosis (DR-TB) and human immunodeficiency virus (HIV) co-infection, characterized by low rates of medication adherence and retention in care. Social workers may have a unique role to play in improving DR-TB-HIV outcomes. We designed, implemented and evaluated a model-based pilot training course on patient-centered care, treatment literacy in DR-TB and HIV coinfection, patient support group facilitation, and self-care. Ten social workers participated in a 1-day training course. Post-training questionnaire scores showed significant overall gains (P = 0.003). A brief training intervention may be a useful and feasible way to engage social workers in patient-centered care for DR-TB and HIV coinfection.

Sequelae of multidrug-resistant tuberculosis: protocol for a systematic review and meta-analysis

INTRODUCTION

The sequelae of multidrug-resistant tuberculosis (MDR-TB) are poorly understood and inconsistently reported. We will aim to assess the existing evidence for the clinical, psychological, social and economic sequelae of MDR-TB and to assess the health-related quality of life in patients with MDR-TB.

METHODS AND ANALYSIS

We will perform a systematic review and meta-analysis of published studies reporting sequelae of MDR-TB. We will search PubMed, SCOPUS, ProQuest, Web of Science and PsychINFO databases up to 5 September 2017. MDR-TB sequelae will include any clinical, psychological, social and economic effects as well as health-related quality of life that occur after MDR-TB treatment or illness. Two researchers will screen the titles and abstracts of all citations identified in our search, extract data, and assess the scientific quality using standardised formats. Providing there is appropriate comparability in the studies, we will use a random-effects meta-analysis model to produce pooled estimates of MDR-TB sequelae from the included studies. We will stratify the analyses based on treatment regimen, comorbidities (such as HIV status and diabetes mellitus), previous TB treatment history and study setting.

ETHICS AND DISSEMINATION

As this study will be based on published data, ethical approval is not required. The final report will be disseminated through publication in a peer-reviewed scientific journal and will also be presented at relevant conferences.

Effectiveness of comprehensive social support interventions among elderly patients with tuberculosis in communities in China: a community-based trial

Background

With the increasing of ageing population, tuberculosis in the elderly brings a challenge for the tuberculosis (TB) control in China. Enough social support can promote the treatment adherence and outcome of the elderly patients with TB. Exploring effective interventions to improve the social support of patients is of great significance for TB management and control.

Methods

A community-based, repeated measurement trial was conducted. Patients with TB >65 years of age were allocated into the intervention or control group. Patients in the intervention group received comprehensive social support interventions, while those in the control group received health education alone. The social support level of patients was measured at baseline and at the first, third and sixth months during the intervention to assess the effectiveness of comprehensive social support interventions.

Results

A total of 201 patients were recruited into the study. Compared with the control group, social support for patients in the intervention group increased significantly over time (β_group*time=0.61, P<0.01) in the following three dimensions: objective support (β_group*time=0.15, P<0.05), subjective support (β_group*time=0.32, P<0.05) and support utilisation (β_group*time=0.16, P<0.05). The change in the scores in the control group was not statistically significant.

Conclusions

The intervention programme in communities, including health education, psychotherapy and family and community support interventions, can improve the social support for elderly patients with TB compared with single health education.

Depression comorbid with tuberculosis and its impact on health status: cross-sectional analysis of community-based data from 48 low- and middle-income countries

BACKGROUND

Depression in tuberculosis increases the risk for adverse health outcomes. However, little is known about comorbid depression and tuberculosis in the general population. Thus, we assessed the association between depression and tuberculosis, and the decrements in health status associated with this comorbidity in 48 low- and middle-income countries.

METHODS

Cross-sectional, community-based data from the World Health Survey on 242,952 individuals aged ≥ 18 years were analyzed. Based on the World Mental Health Survey version of the Composite International Diagnostic Interview, past 12-month depression was categorized into depressive episode, brief depressive episode, subsyndromal depression, and no depression. Health status across six domains (cognition, interpersonal activities, sleep/energy, self-care, mobility, pain/discomfort) was assessed. Multivariable logistic and linear regression analyses were performed to assess the associations.

RESULTS

The prevalence of depressive episode among those with and without tuberculosis was 23.7% and 6.8%, respectively (P < 0.001). Tuberculosis was associated with a 1.98 (95% CI 1.47-2.67), 1.75 (95% CI 1.26-2.42), and 3.68 (95% CI 3.01-4.50) times higher odds for subsyndromal depression, brief depressive episode, and depressive episode, respectively. Depressive episode co-occurring with tuberculosis was associated with significantly worse health status across all six domains compared to tuberculosis alone. Interaction analysis showed that depression significantly amplifies the association between TB and difficulties in self-care but not in other health domains.

CONCLUSIONS

Depression is highly prevalent in adults with tuberculosis, and is associated with worse health status compared to tuberculosis without depression. Public health efforts directed to the recognition and management of depression in people with tuberculosis may lead to better outcomes.

Mental disorders and drug/alcohol use in patients commencing extensively drug-resistant tuberculosis treatment

Mental disorders and alcohol/drug use worsen treatment outcomes for multidrug-resistant tuberculosis (TB), but data are lacking for extensively drug-resistant (XDR) TB. We investigated the association of baseline mental disorders and alcohol/drug use on XDR-TB treatment outcomes in a retrospective study of 53 XDR-TB Peruvian patients during 2010-2012. Logistic regression estimated the odds ratios for unfavourable XDR-TB treatment outcomes. Overall treatment success was 25%. Mental disorders and drug/alcohol use were found in respectively 22.4% and 20.4% of patients; neither were associated with unfavourable treatment outcomes. Future research should explore the relationship between mental health and drug/alcohol use in XDR-TB treatment outcomes.

The epidemiology, pathogenesis, transmission, diagnosis, and management of multidrug-resistant, extensively drug-resistant, and incurable tuberculosis

Global tuberculosis incidence has declined marginally over the past decade, and tuberculosis remains out of control in several parts of the world including Africa and Asia. Although tuberculosis control has been effective in some regions of the world, these gains are threatened by the increasing burden of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis. XDR tuberculosis has evolved in several tuberculosis-endemic countries to drug-incurable or programmatically incurable tuberculosis (totally drug-resistant tuberculosis). This poses several challenges similar to those encountered in the pre-chemotherapy era, including the inability to cure tuberculosis, high mortality, and the need for alternative methods to prevent disease transmission. This phenomenon mirrors the worldwide increase in antimicrobial resistance and the emergence of other MDR pathogens, such as malaria, HIV, and Gram-negative bacteria. MDR and XDR tuberculosis are associated with high morbidity and substantial mortality, are a threat to health-care workers, prohibitively expensive to treat, and are therefore a serious public health problem. In this Commission, we examine several aspects of drug-resistant tuberculosis. The traditional view that acquired resistance to antituberculous drugs is driven by poor compliance and programmatic failure is now being questioned, and several lines of evidence suggest that alternative mechanisms-including pharmacokinetic variability, induction of efflux pumps that transport the drug out of cells, and suboptimal drug penetration into tuberculosis lesions-are likely crucial to the pathogenesis of drug-resistant tuberculosis. These factors have implications for the design of new interventions, drug delivery and dosing mechanisms, and public health policy. We discuss epidemiology and transmission dynamics, including new insights into the fundamental biology of transmission, and we review the utility of newer diagnostic tools, including molecular tests and next-generation whole-genome sequencing, and their potential for clinical effectiveness. Relevant research priorities are highlighted, including optimal medical and surgical management, the role of newer and repurposed drugs (including bedaquiline, delamanid, and linezolid), pharmacokinetic and pharmacodynamic considerations, preventive strategies (such as prophylaxis in MDR and XDR contacts), palliative and patient-orientated care aspects, and medicolegal and ethical issues.

Development of a Patient-Centred, Psychosocial Support Intervention for Multi-Drug-Resistant Tuberculosis (MDR-TB) Care in Nepal

Multi-drug-resistant tuberculosis (MDR-TB) poses a major threat to public health worldwide, particularly in low-income countries. The current long (20 month) and arduous treatment regime uses powerful drugs with side-effects that include mental ill-health. It has a high loss-to-follow-up (25%) and higher case fatality and lower cure-rates than those with drug sensitive tuberculosis (TB). While some national TB programmes provide small financial allowances to patients, other aspects of psychosocial ill-health, including iatrogenic ones, are not routinely assessed or addressed. We aimed to develop an intervention to improve psycho-social well-being for MDR-TB patients in Nepal. To do this we conducted qualitative work with MDR-TB patients, health professionals and the National TB programme (NTP) in Nepal. We conducted semi-structured interviews (SSIs) with 15 patients (10 men and 5 women, aged 21 to 68), four family members and three frontline health workers. In addition, three focus groups were held with MDR-TB patients and three with their family members. We conducted a series of meetings and workshops with key stakeholders to design the intervention, working closely with the NTP to enable government ownership. Our findings highlight the negative impacts of MDR-TB treatment on mental health, with greater impacts felt among those with limited social and financial support, predominantly married women. Michie et al's (2011) framework for behaviour change proved helpful in identifying corresponding practice- and policy-level changes. The findings from this study emphasise the need for tailored psycho-social support. Recent work on simple psychological support packages for the general population can usefully be adapted for use with people with MDR-TB.

Tuberculosis and mental health in the Asia-Pacific

OBJECTIVE

This opinion piece encourages mental health researchers and clinicians to engage with mental health issues among tuberculosis patients in the Asia-Pacific region in a culturally appropriate and ethical manner. The diversity of cultural contexts and the high burden of tuberculosis throughout the Asia-Pacific presents significant challenges. Research into tuberculosis and mental illness in this region is an opportunity to develop more nuanced models of mental illness and treatment, while simultaneously contributing meaningfully to regional tuberculosis care and prevention.

CONCLUSIONS

We overview key issues in tuberculosis and mental illness co-morbidity, highlight ethical concerns and advocate for a regional approach to tuberculosis and mental health that is consistent with the transnational challenges presented by this airborne infectious disease. Integrating tuberculosis and mental health services will go a long way to addressing the needs of vulnerable populations and stopping the transmission of one of the world's biggest infectious killers.

Qualitative interviews with non-national tuberculosis patients in Cairo, Egypt: understanding the financial and social cost of treatment adherence

Limited data are available about the challenges of non-national TB patients undergoing long-term treatment courses in an urban setting. This study aimed to understand the financial and social cost of adherence of non-national TB patients in Cairo, Egypt as a means to inform the development of context-specific interventions to support treatment adherence. In 2011, 22 in-depth interviews were conducted with TB patients from Sudan, Ethiopia, Eritrea, Somalia and Djibouti to obtain qualitative data. Analysis was based on thematic analysis that aimed to identify recurrent themes and codes from the narratives. The study identified a number of factors that influence TB treatment adherence. Uncertain financial status due to limited or no employment was frequently discussed in interviews, which resulted in fear of not being able to support family, loss of pride, dependence on family and friends, fear of losing housing, food insecurity and limited food options. Respondents also feared infecting other household members and longed for opportunities to discuss their illness and treatment experiences with other individuals but their social networks were often limited. TB-related stigma was driven by shame and blame of infection. Respondents also believed stigma was based on their foreign origin. Stigma manifested in distancing and exclusion in various ways, resulting in isolation, psychological distress and reluctance to disclose TB status to others. Poverty-related factors and social context with a special focus on stigma should be considered when developing strategies for supporting long-term treatment courses for non-national patients in Cairo and other similar urban settings.

Psycho-Socio-Economic Issues Challenging Multidrug Resistant Tuberculosis Patients: A Systematic Review

Background

Limited treatment options, long duration of treatment and associated toxicity adversely impact the physical and mental well-being of multidrug-resistant tuberculosis (MDR-TB) patients. Despite research advances in the microbiological and clinical aspects of MDR-TB, research on the psychosocial context of MDR-TB is limited and less understood.

Methodology

We searched the databases of PubMed, MEDLINE, Embase and Google Scholar to retrieve all published articles. The final manuscripts included in the review were those with a primary focus on psychosocial issues of MDR-TB patients. These were assessed and the information was thematically extracted on the study objective, methodology used, key findings, and their implications. Intervention studies were evaluated using components of the methodological and quality rating scale. Due to the limited number of studies and the multiple methodologies employed in the observational studies, we summarized these studies using a narrative approach, rather than conducting a formal meta-analysis. We used ‘thematic synthesis’ method for extracting qualitative evidences and systematically organised to broader descriptive themes.

Results

A total of 282 published articles were retrieved, of which 15 articles were chosen for full text review based on the inclusion criteria. Six were qualitative studies; one was a mixed methods study; and eight were quantitative studies. The included studies were divided into the following issues affecting MDR-TB patients: a) psychological issues b) social issues and economic issues c) psychosocial interventions. It was found that all studies have documented range of psychosocial and economic challenges experienced by MDR-TB patients. Depression, stigma, discrimination, side effects of the drugs causing psychological distress, and the financial constraints due to MDR-TB were some of the common issues reported in the studies. There were few intervention studies which addressed these psychosocial issues most of which were small pilot studies. There is dearth of large scale randomized psychosocial intervention studies that can be scaled up to strengthen management of MDR-TB patients which is crucial for the TB control programme.

Conclusion

This review has captured the psychosocial and economic issues challenging MDR patients. However there is urgent need for feasible, innovative psychosocial and economic intervention studies that help to equip MDR-TB patients cope with their illness, improve treatment adherence, treatment outcomes and the overall quality of life of MDR-TB patients.
