Impact of community-based adherence support on treatment outcomes for tuberculosis, leprosy and HIV/AIDS-infected individuals in post-Ebola Liberia.

BACKGROUND: Partners In Health (PIH) committed to improving health care delivery in Maryland County, Liberia following the Ebola epidemic by employing 71 community health workers (CHWs) to provide treatment support to tuberculosis (TB), HIV and leprosy patients. PIH simultaneously deployed a socioeconomic assistance program with three core components: transportation reimbursement to clinics; food support; and additional social assistance in select cases. OBJECTIVE: This study aimed to evaluate how a CHW program for community treatment support and addressing socioeconomic barriers to care can impact patient outcomes in a post-conflict and post-epidemic context. METHODS: Retrospective observational study utilizing registry data from 513 TB, 447 HIV and 75 leprosy patients at three health facilities in Maryland County, Liberia. Treatment coverage and clinical outcomes for patient cohorts enrolled in the pre-intervention period (January 2015 to June 2015) and the post-intervention period (July 2015 to July 2017) are compared using logistic regression analyses. RESULTS: TB treatment coverage increased from 7.7% pre-intervention to 43.2% (p < 0.001) post-intervention and lost to follow-up (LTFU) rates decreased from 9.5% to 2.1% (p = 0.003). ART treatment coverage increased 3.8 percentage points (p = 0.03), with patient retention improving 63.9% to 86.1% (p < 0.001); a 6.0 percentage point decrease in HIV LTFU was also observed (p = 0.21). Despite an 84.3% treatment success rate observed for leprosy patients, pre-intervention data was largely unavailable and statistical significance could not be reached for any treatment outcomes pre-post intervention. CONCLUSIONS: The PIH approach to CHW community treatment support in Liberia demonstrates how, with the right inputs, excellent clinical outcomes are possible even in post-conflict and post-epidemic contexts. Care should be taken to position and support CHWs so that they have the opportunity to succeed, including full integration and recognition within the system, and the addition of clinical system improvements and social supports that are too often dismissed as unsustainable.

Knowledge of the patients regarding leprosy and adherence to treatment.

Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It is known for its great disfiguring capacity and is considered an extremely serious disease to public health worldwide. The state of Ceará ranks 13th in number of cases of leprosy in Brazil, and fourth in Northeastern region, with an average of 2,149 new cases diagnosed every year. This study aimed to evaluate the knowledge of leprosy patients regarding treatment, and to assess the level of treatment adherence and its possible barriers. The study was conducted in the reference center for dermatology, from September 2010 to October 2010, in Fortaleza, Ceará. The study data were collected by means of a structured interview, along with the Morisky-Green test, in order to assess treatment adherence and barriers to adherence. A total of 70 patients were interviewed, out of whom 66 were new cases. The majority of patients were between 42 and 50 years old, and 37 (52.9%) were male. Most patients were clinically classified as presenting multibacillary leprosy (80%), and 78.6% of them were from Fortaleza, Brazil. The Morisky-Green test indicated that 62.9% of patients presented a low level of adherence (p<0.005), despite claiming to aware of the disease risks. However, it was observed that 57.1% of the patients had no difficulty adhering to treatment, while 38.6% reported little difficulty. This study shows that despite the patients claiming to be familiar with leprosy and its treatment, the Morisky-Green test clearly demonstrated that they actually were not aware of the principles of therapy, which is evidenced by the low degree of treatment adherence.

Twenty five years follow up of MB leprosy patients retreated with a modified MDT regimen after a full course of dapsone mono-therapy.

BACKGROUND: The relentless emergence of dapsone resistance amongst M. leprae threatened leprosy control programmes, and increased the relapse rate of patients cured with dapsone monotherapy. OBJECTIVE: The study aimed to analyse the effect on the relapse rate of dapsone-cured multibacillary (MB) leprosy patients, of re-treatment, using a multidrug therapy (MDT) regimen which differed from the WHO recommended regimen. DESIGN: 794 MB leprosy patients who had been released from treatment after dapsone monotherapy were selected, amongst them 657 were re-treated for 1 year using the modified multidrug therapy regimen (mMDT) including rifampicin, clofazimine and dapsone, and 137 patients were observed as control cases. RESULTS: The regimen was well tolerated with good compliance: 620 patients completed re-treatment with mild side effects and a low incidence of leprosy reactions. There was a statistically significant difference between the relapse rates of re-treated and control groups (chi squaredf = 57.44, P < 0.001). Furthermore, the relapses in the re-treated group were significantly more likely to be later than those in the control group (t = 25.62, P < 0.001). CONCLUSIONS: Re-treatment with this modified regimen is acceptable and can reduce the risk of early relapse in dapsone-cured patients. The problem of persisters causing late relapse is likely to remain.

[Evaluation and control of missing contacts of leprosy patients]. / Avaliação e controle de contatos faltosos de doentes com hanseníase.

Descriptive study, with qualitative variables, carried on in the Ambulatory of Specialties Region of Taubaté, in order to evaluate the missing contacts of leprosy patients. Thirty-six records of new cases were analyzed, from January 2003 to July 2004. Ninety-two contacts were identified, being 64.1% missing ones, having 25% from 20 to 29 years and 58.5% female. Of these, 61% were submitted to consultation of home nursing. Reported non-membership to the control for forgetfulness (66.6%), and lack of time (11.1%), 4 contacts had symptoms of leprosy, and 1 was confirmed (transmissible form - Dimorfa). Without achieving 100% coverage active search, we suggest, to ensure the goal of eliminating of the disease, partnerships and decentralization of the control activities.

Impact of scarcity of automobile fuel on attendance at a referral centre for tuberculosis in Nigeria.

BACKGROUND: Tuberculosis in its pulmonary and extra-pulmonary form is still a common finding in the developing world. This study was to investigate the impact of a period of scarcity of automobile fuel in the Niger-Delta area of Nigeria on attendance at a Tuberculosis Referral Centre in Igbogene, Yenagoa, Bayelsa State. METHODS: Data was collected on attendance before, during and after the scarcity. This Tuberculosis and Leprosy Control Centre is run by a German non-governmental organization. (NGO), and the State's Ministry of Health. No user fee is charged. RESULTS: During the period of scarcity of automobile fuel, the total 12-months attendance of males decreased to 25.1% of that before the advent of scarcity. Attendance rose in the post-scarcity period, but reached only 78.5% of the pre-scarcity level. For females, the 12 months attendance during the scarcity period reduced to 75.3% of the pre-scarcity level. The 12-months attendance by females rose in the post-scarcity period to 109.2% above the pre-scarcity level. There was no evidence of an increase in attendance over the course of the period of automobile fuel scarcity among either males or females. CONCLUSION: The scarcity of automobile fuel which usually translated to an increase in cost of transportation probably increased the number of untreated tuberculosis patients in the population with potential serious long term health implications. The provision of vehicles as well as facility for storage of automobile fuel to this referral Centre by either the NGO or the Ministry of Health is suggested. This would allow the Centre carry out domiciliary service to these patients.

Gender differences in epidemiological factors associated with treatment completion status of leprosy patients in the most hyperendemic district of Nepal.

The introduction of multidrug therapy (MDT), recommended by WHO, has been a major advance in the treatment of leprosy because of its relatively short treatment course and low rate of relapse. Although leprosy treatment is provided to both sexes equally, in most parts of the world significant differences have been found in treatment status. The main objective of the study was to investigate gender differences in epidemiological factors associated with treatment status of leprosy patients. An analytic cross-sectional study was carried out in the most hyperendemic Dhanusa District, Nepal. Stratified random sampling was applied for selection of the patients. Statistical analysis of the differences in treatment status, between males and females, and among other epidemiological factors of interest was carried out using multiple logistic regression. Chi-square/Fisher's exact test were also used to assess significant differences in values between males and females. There were 580 leprosy patients (385 male and 195 female) aged >15 years registered for MDT between April 1, 2001 to March 31, 2002 in the 16 main health centers of the district. Of the 580 patients, a total of 273 (183 male and 90 female) were included in the study, to collect data on clinical type of leprosy, patterns of physical deformity/disability, site of skin lesions, and socio-demographic information. There were 183 male (68.3% on MB-MDT) and 90 female (61.1% MB-MDT) leprosy patients. We found that 79.2% of male patients completed treatment, while 34.4% female patients did not complete within the given time frame. Significant gender differences among leprosy patients were found in the distribution of disability grades and treatment completion status. However, there was no significant gender difference in the distribution of leprosy types and skin lesion sites. The study also found significant associations between treatment completion status and gender (adjusted OR 2.05, 95% CI: 1.07-3.94), educational status (adjusted OR 2.37, 95% CI: 1.12-4.99), disability grade I (adjusted OR 3.14, 95% CI: 1.23-8.04), and disability grade 0 (adjusted OR 2.92, 95% CI: 1.14-7.47) after adjustment for all other leprosy/demographic factors.

Efeitos adversos da poliquimioterapia em pacientes com hanseníase: um levantamento de cinco anos em um Centro de Saúde da Universidade Federal de Uberlândia / Adverse effects of multidrug therapy in leprosy patients: a five-year survey at a Health Center of the Federal University of Uberlandia

The introduction of multidrug therapy (WHO/MDT)-composed by the drugs dapsone, clofazimine and rifampicin has enabled the cure of Hansen's disease, however, the adverse effects of these drugs were not given priority by the health team. Aiming to determine MDT's adverse effects' magnitude and relate them to the non-adhesion of patients to the treatment, a study of 187 charts of patients treated with MDT from January of 1995 to May 2000, was carried out at a Health Center of the Federal University of Uberlandia. Side effects were recorded in 71 patients' charts. Among the 113 side effects found, 80 (70.7 per cent) were related to dapsone, 7 (6.2 per cent) were caused by rifampicin and 26 (20.5 per cent) were attributed to clofazimine. These effects induced 28 (14.9 per cent), patients to change the therapeutic scheme, representing 39.4 per cent from the 71 patients with adverse effects. Throughout this study, the importance is discussed of considering MDT's adverse effects when training the health team to heighten the patient's adhesion to the treatment and thereby collaborating to eliminate Hansen's disease as a public health problem.
