RESUMEN

We aimed to elucidate the specific roles and responsibilities of expert clients in service delivery among adolescents living with HIV in Eswatini, and to provide recommendations for enhancing adolescent service provision among expert clients and similar lay health workers throughout low- and middle-income countries. An exploratory qualitative descriptive methodology using conventional content analysis was used to meet our study aims. We recruited 20 expert clients and 12 key informants (programme managers, programme coordinators and nurses) to participate in semi-structured interviews, and we arranged four focus group discussions among adolescents living with HIV with seven to ten participants per focus group. Adherence counselling in clinical and community settings was considered paramount to the roles and responsibilities of expert clients with regard to adolescent-specific HIV service delivery. The following recommendations were made to enhance expert client service delivery practices among adolescents: (1) training in adolescent developmental, sexual and reproductive needs; (2) training to enhance clinical knowledge and skills; (3) additional work equipment and compensation; and d) more parent and guardian engagement in their work. While expert clients meet the needs of adolescents living with HIV in several capacities, they require additional resources, skills and training to improve their work, especially in the realm of sexual and reproductive health. Future research is needed to evaluate the impact of expert client service delivery on adolescent health outcomes.

RESUMEN

OBJECTIVE: To describe the implementation, use and cost of a phone-based tuberculosis case finding and case management intervention during the coronavirus disease 2019 (COVID-19) pandemic in two regions in the Philippines. METHODS: We implemented this phone-based intervention to maintain tuberculosis treatment support, active case finding and contact investigation efforts in 42 facilities, starting in June 2020. We established a dedicated mobile phone number for each centre and promoted the intervention on different media platforms. We recruited and trained staff members and provided them with tools for screening and patient follow-up. We collected data on tuberculosis screening, diagnosis and treatment initiation for this intervention and three comparator interventions over the same period. We collected data on number and type of calls placed and received. We estimated the additional cost of this intervention compared to the standard of care. FINDINGS: From October 2020 to September 2021, 14 tuberculosis contact centres, for which complete data were available, identified 43.5% (827/1901) of patients with bacteriologically confirmed tuberculosis enrolled in treatment among all comparator interventions. These centres managed 6187 calls over the same period. The additional cost of implementing and running the centre for 12 months was 398 United States dollars per facility. CONCLUSION: The tuberculosis contact centre is a low-technology telehealth intervention which contributed to overall treatment initiation during the COVID-19 pandemic. Additional work should assess the extent to which the contact centre identifies tuberculosis patients previously missed by the health system, regardless of the pandemic.

RESUMEN

The accelerated development of coronavirus disease (COVID-19) candidate vaccines is intended to achieve worldwide immunity. Ensuring COVID-19 vaccination is crucial to stemming the pandemic, reclaiming everyday life, and helping restore economies. However, challenges exist to deploying these vaccines, especially in resource-limited sub-Saharan Africa. In this article, we highlight lessons learned from previous efforts to scale up vaccine distribution and offer considerations for policymakers and key stakeholders to use for successful COVID-19 vaccination rollout in Africa. These considerations range from improving weak infrastructure for managing data and identifying adverse events after immunization to considering financing options for overcoming the logistical challenges of vaccination campaigns and generating demand for vaccine uptake. In addition, providing COVID-19 vaccination can be used to promote the adoption of universal healthcare, especially in sub-Saharan Africa countries.

RESUMEN

Coronavirus disease has disrupted tuberculosis services globally. Data from 33 centers in 16 countries on 5 continents showed that attendance at tuberculosis centers was lower during the first 4 months of the pandemic in 2020 than for the same period in 2019. Resources are needed to ensure tuberculosis care continuity during the pandemic.

RESUMEN

BACKGROUND: Philippines, Indonesia, and Bangladesh are three high tuberculosis (TB) burden countries in Asia which account for 18% of the estimated global TB incidence (1.8 million) and 15% of TB related deaths (192,000). In 2017 alone, approximately 785,000 of the incident TB cases in these countries remained missing, including diagnosed but not notified. METHODS: We reviewed the published data from the most recent TB prevalence surveys conducted in Bangladesh, Indonesia, and the Philippines. The prevalence rates established by the surveys were used to estimate the disease burden of these countries for 2017. The Global TB Report 2017 and World Health Organization's (WHO) global TB database were sourced for collection of incidence and notification data by age groups and types of TB to estimate prevalence to notification gaps 2017. RESULTS: According to the surveys, the estimated prevalence rates of bacteriologically confirmed TB and smear-positive TB are 287 and 113 for Bangladesh (2015-16), 759 and 256 for Indonesia (2013-14) and 1159 and 434 for the Philippines (2016) per 100,000 population over the age of 15 years. The overall national TB prevalence estimates for all forms is 260 for Bangladesh, 660 for Indonesia, and 970 for the Philippines (2016). Compared with the incidence rate, the proportion of total notified cases is 67% for Bangladesh, 52% for Indonesia, and 55% for the Philippines. Bangladesh has been able to detect almost 100% of the prevalent pulmonary TB, while Indonesia and Philippines have detected only 30 and 22% of these infectious cases respectively. Although notification has been improving over the years, there is no impact on the incidence rate since a large proportion of the undiagnosed cases, and delayed diagnosis continue to feed the transmission process. CONCLUSION: The surveys have provided data that is critical for developing realistic strategies for these countries to eliminate TB. In general, this paper recommends interventions for strengthening diagnosis of pulmonary TB, implementing targeted communication programs and active case finding to reduce patient level delays, expanding public-private partnership to increase access to TB services, using rapid diagnostics, and providing social protection for vulnerable populations. These measures can accelerate these countries' progress towards achieving End TB goals.

RESUMEN

BACKGROUND: Diagnosis of tuberculosis is difficult among pregnant women because the signs and symptoms of the disease, such as fatigue, shortness of breath, sweating, cough, and mild fever are similar to some manifestations of pregnancy. It is particularly challenging among HIV-infected women as symptoms are often masked or atypical. Currently, WHO recommends a standard four-symptom screening tool for pregnant and lactating women. There is evidence from South Africa that this screening tool (which, despite complex symptomology in this population, recommends identification of patients with weight loss, fever, current cough and night sweats), may be missing true active TB cases. However there exist several laboratory and clinical procedures that have the potential to improve the sensitivity and specificity of this screening tool. METHODS: This study will evaluate the sensitivity and specificity of the current TB screening tool for pregnant and lactating women, both HIV positive and negative. We will also assess several different enhanced screening algorithm using LAM, IGRA, TST and chest radiography and clinical/laboratory procedures and tests. The study will use a cross-sectional analytical study design involving pregnant and lactating women up to six months post-delivery attending antenatal or postnatal care, respectively in one of three selected public health units in Swaziland. Participants will be consecutively enrolled and will be in one of four groups of interest: HIV infected pregnant women, non-HIV infected pregnant women, HIV infected lactating women and non-HIV infected lactating women. DISCUSSION: We expect in conducting all procedures on all participants regardless of result of the symptom screening we may experience a high refusal rate. However, this risk will be mitigated by the long data collection period of five or more months.

RESUMEN

Objective: This study describes the availability of basic services, equipment, and commodities for integrated DM-TB services, best practices by healthcare workers, and opportunities for better integration of DM-TB care in Eswatini. Methods: A qualitative design was used. Twenty-three healthcare workers participated in a survey and key informant interview. Results: Most respondents indicated DM and TB care are integrated and clients access blood pressure and fasting/random blood glucose assessment. Few respondents indicated they provide visual assessment, hearing assessment, and HbA1c testing. Respondents experienced stockouts of urinalysis strips, antihypertensive drugs, insulin, glucometer strips, and DM drugs in the previous 6 months before the interview. Four main themes emerged from the qualitative interviews-quality and current standards of care, best practices, opportunities, and recommendations to improve integrated services delivery. Conclusion: While DM care is provided for TB patients, the implementation of integrated DM-TB services is suboptimal as the quality and current standards of care vary across health facilities due to different patient-level and health system challenges. Some identified opportunities must be utilized for a successful DM-TB integration.

RESUMEN

Objectives: To describe the impact of the COVID-19 pandemic on tuberculosis services and the different approaches healthcare workers adopted to ensure continued tuberculosis service delivery in Eswatini. Study design: This is a qualitative study with a cross-sectional design. Methods: Thirteen nurses and 9 doctors who provide tuberculosis care from 10 health facilities participated in an in-depth interview to describe how the COVID-19 pandemic affected tuberculosis services and the approaches adopted to ensure continued patient care. Twenty in-person and 2 telephone interviews were conducted. The participating facilities were selected based on a ranking criterion of the number of patients seen. Data were analyzed using thematic content analysis. NVivo 12 software was used for qualitative analysis, and the Consolidated Criteria guided the study for Reporting Qualitative research (COREQ). Results: Two major themes emerged: COVID-19 impacted services delivery and access; and best practices that ensured healthcare services delivery. Six sub-themes describe how COVID-19 impacted services: all attention focused on COVID-19; COVID worsened the health system challenges; COVID hindered patients from accessing care; patients defaulted due to the lockdown; COVID impacted the quality of care and increased the risk of infection among healthcare workers. Five sub-themes describe best practices that ensure continued service delivery: Home-based care, Patient support, Patient Education, Integrated Services, and Staff rotation. Conclusion: While various strategies were adopted globally to mitigate the impact of the COVID-19 pandemic, these strategies need contextualization to be effective and sustainably incorporated into routine care to ensure continuity of and access to TB and other healthcare services.

RESUMEN

Background: The rollout of GeneXpert aimed at increasing early diagnosis of tuberculosis to improve treatment outcomes and global tuberculosis targets. Objective: This study evaluated trends in tuberculosis diagnosis and outcomes pre- and post-introduction of GeneXpert in three African countries - the Democratic Republic of the Congo (DRC), Nigeria and South Africa. Methods: Data from 2001 to 2019 were extracted from the World Health Organization's data repository. Descriptive analysis, paired t-tests and interrupted time series models were used. Results: Estimated tuberculosis incidence decreased from 327/100 000 to 324/100 000 in the DRC, and from 1220/100 000 to 988/100 000 in South Africa. Incidence remained at 219/100 000 in Nigeria. The tuberculosis case notification rate did not change significantly. Increases in the new case treatment success rates were statistically significant (DRC: p = 0.0201; Nigeria: p = 0.0001; South Africa: p = 0.0017); decreases in mortality were also statistically significant (DRC: p = 0.0264; Nigeria: p = 0.0001; South Africa: p < 0.0001). Time series models showed insignificant increases in new tuberculosis cases in DRC (n = 1856, p = 0.085) and Nigeria (n = 785, p = 0.555) from 2011 to 2019; and a statistically significant decrease in South Africa (n = 15 269, p = 0.006). Conclusion: Improvements in tuberculosis treatment outcomes were achieved, but little progress has been made in new case notification due to varied implementation and scale-up of GeneXpert across the three countries. Implementation barriers need to be addressed to achieve the required tuberculosis targets.

RESUMEN

OBJECTIVE: The declaration of the coronavirus disease (COVID-19), a pandemic in early 2020, has seen an upsurge in research globally to fill gaps in the epidemiology of the SARS-CoV-2 virus impact on health care and clinical management, as well as possible prevention and treatment modalities. Published literature on the different types of COVID-19 research conducted globally is varied and is particularly limited in Africa. This study sets out to describe the COVID-19-related research registered and conducted on the African continent. METHODS: This is a cross-sectional study of all COVID-19-related studies available in the WHO's International Clinical Trials Registry Platform (ICTRP) repository. We extracted studies registered from March 1, 2020, to July 15, 2021. A descriptive analysis of the extracted data was performed, and the findings were presented. RESULTS: At extraction, a total of 12,533 COVID-19-related studies were listed on the ICTRP portal. We included 9803 studies, after excluding 2060 duplicate records and 686 records without a site/country. While 9347 studies (96%) were conducted outside of Africa, only 456 studies (4%) were conducted in the African continent, of which 270 (59.2%) were interventional studies, and 184 (40.4%) were observational studies. About 80% of the studies were conducted in Egypt and South Africa, and most of these involved testing of drugs and biologicals. CONCLUSION: The African continent hosts considerably fewer COVID-19-related research compared to other parts of the world. This may have implications on scientific evidence available for implementing COVID-19 control efforts. There is, therefore, a need for local funding and ownership of research projects and north-south collaboration in research.

RESUMEN

Peripheral neuropathy (PN) is a serious condition affecting the nerves that is commonly seen in patients with tuberculosis (TB). Causes of PN in patients with TB are multiple, and can include TB itself, other co-morbid conditions, such as Human Immune-deficiency virus (HIV) disease, malnutrition, or diabetes mellitus (DM), and several anti-tuberculous medications. The condition can manifest with a variety of symptoms, and a diagnosis can usually be made on a clinical basis. Treatment and prognosis of PN vary depending on the underlying cause, but often the condition can lead to permanent disability in individuals with TB. For this reason, primary prevention is key as is early identification and management of symptoms. Treatment can include withdrawal of possible offending agents, vitamin supplementation, physical therapy, analgesics, and targeted agents, including tricyclic antidepressants, selective serotonin reuptake inhibitors, and gabapentin. Additional research is needed to better describe the morbidity and disability associated with PN in persons with TB and to improve management strategies for persons at risk for and affected by this condition. Case review: RM is a 47 year-old man who is in his third month of treatment for drug-resistant TB (DR-TB). His treatment regimen consists of kanamycin (1 gm intramuscular daily), levofloxacin (1000 mg by mouth daily), cycloserine (750 mg by mouth daily), ethionamide (750 mg by mouth daily), pyrazinamide (1500 mg by mouth daily), and Para-Amino Salicylate (12 gm by mouth daily). He is HIV-infected with a CD4 count of 470 cell/µl and on a stable antiretroviral therapy regimen of tenofovir, lamivudine, and efavirenz, which he started 8 weeks ago. He works in a platinum mine, denies smoking, reports drinking beer "on the weekend" and denies other drugs. He presents for his 3 month clinical visit for his DR-TB follow-up and states he is doing well, but he does report some "burning" in the bottom of his feet.
