Objective: Leprosy post-exposure prophylaxis with single-dose rifampicin (SDRPEP) has proven effective and feasible, and is recommended by WHO since 2018. This SDR-PEP toolkit was developed through the experience of the leprosy post-exposure prophylaxis (LPEP) programme. It has been designed to facilitate and standardise the implementation of contact tracing and SDR-PEP administration in regions and countries that start the intervention. Results: Four tools were developed, incorporating the current evidence for SDRPEP and the methods and learnings from the LPEP project in eight countries. (1) the SDR-PEP policy/advocacy PowerPoint slide deck which will help to inform policy makers about the evidence, practicalities and resources needed for SDR-PEP, (2) the SDR-PEP field implementation training PowerPoint slide deck to be used to train front line staff to implement contact tracing and PEP with SDR, (3) the SDR-PEP generic field guide which can be used as a basis to create a location specific field protocol for contact tracing and SDR-PEP serving as a reference for frontline field staff. Finally, (4) the SDR-PEP toolkit guide, summarising the different components of the toolkit and providing instructions on its optimal use. Conclusion: In response to interest expressed by countries to implement contact tracing and leprosy PEP with SDR in the light of the WHO recommendation of SDRPEP, this evidence-based, concrete yet flexible toolkit has been designed to serve national leprosy programme managers and support them with the practical means to translate policy into practice. The toolkit is freely accessible on the Infolep homepages and updated as required: https://www.leprosy-information.org/keytopic/leprosy-postexposure-prophylaxis-lpep-programme(AU).

Programa post-exposición a la profilaxis de la Lepra (LPEP): Actualización y análisis interno / No disponible

Se requieren nuevos planteamientos para incrementar el control de la lepra, disminuir el número de personas afectadas y cortar la transmisión. Para conseguir este objetivo las mejores soluciones son la detección precoz. El cribaje de contactos y la quimioprofilaxis. El Programa Profilaxis Post-exposición a la Lepra (LPEP) ayuda a demostrar la viabilidad de integrar el rastreo de contactos y dosis única de rifampicina (SDR) en las actividades rutinarias de control de la enfermedad. El programa LPEP está implementado entre los programas de control de la lepra de Brasil, Camboya, India, Indonesia, Myanmar, Nepal, Sri Lanka y Tanzania. Se centra en tres objetivos: rastro de contactos de nuevos pacientes diagnosticados de lepra, cribaje de contactos y administración de SDR a los contactos seleccionados. Las adaptaciones de protocolos países-específicos se refieren a la definición de contacto, edad mínima para SDR y personal implicado. La calidad de la evidencia se mantiene mediante coordinación central, documentación detallada y supervisión. Ya se han completado alrededor de 2 años de trabajo de campo en siete países en julio de 2017. Los 5,941 pacientes índice registrados (89·4% de los registrados) han identificado un total de 123,311 contactos, de los cuales el 99·1% ha sido rastreado y cribado. De entre ellos, se identificaron 406 nuevos pacientes de lepra (329/100,000) y a 10,883 (8·9%) no se les administró SDR por diversos motivos. También 785 contactos (6·7%) rehusó tomar la profilaxis con SDR. En total, se administró SDR al 89·0% de los contactos registrados. La profilaxis post-exposición con SDR es segura; se puede integrar en los programas rutinarios de control de la lepra y es generalmente bien aceptada por el paciente índice, sus contactos y el personal sanitario. El programa también consigue estimular los programas locales de control de la lepra

Innovative approaches are required to further enhance leprosy control, reduce the number of people developing leprosy, and curb transmission. Early case detection, contact screening, and chemoprophylaxis currently is the most promising approach to achieve this goal. The Leprosy Post-Exposure Prophylaxis (LPEP) programme generates evidence on the feasibility of integrating contact tracing and single-dose rifampicin (SDR) administration into routine leprosy control activities in different settings. The LPEP programme is implemented within the leprosy control programmes of Brazil, Cambodia, India, Indonesia, Myanmar, Nepal, Sri Lanka and Tanzania. Focus is on three key interventions: tracing the contacts of newly diagnosed leprosy patients; screening the contacts for leprosy; and administering SDR to eligible contacts. Country-specific protocol adaptations refer to contact definition, minimal age for SDR, and staff involved. Central coordination, detailed documentation and rigorous supervision ensure quality evidence. Around 2 years of field work had been completed in seven countries by July 2017. The 5,941 enrolled index patients (89·4% of the registered) identified a total of 123,311 contacts, of which 99·1% were traced and screened. Among them, 406 new leprosy patients were identified (329/100,000), and 10,883 (8·9%) were excluded from SDR for various reasons. Also, 785 contacts (0·7%) refused the prophylactic treatment with SDR. Overall, SDR was administered to 89·0% of the listed contacts. Post-exposure prophylaxis with SDR is safe; can be integrated into the routines of different leprosy control programmes; and is generally well accepted by index patients, their contacts and the health workforce. The programme has also invigorated local leprosy control

Assessing the feasibility of integration of self-care for filarial lymphoedema into existing community leprosy self-help groups in Nepal.

BACKGROUND: Lymphatic filariasis (LF) and leprosy are disabling infectious diseases endemic in Nepal. LF infection can lead to lymphoedema and hydrocoele, while secondary effects of leprosy infection include impairments to hands, eyes and feet. The disabling effects of both conditions can be managed through self-care and the supportive effects of self-help groups (SHGs). A network of SHGs exists for people affected by leprosy in four districts in Nepal's Central Development Region, however no such service exists for people affected by LF. The aim of this study was to determine the feasibility of integrating LF affected people into existing leprosy SHGs in this area. METHODS: A survey was conducted using a semi-structured questionnaire to elicit information on: (i) participant characteristics, clinical manifestation and disease burden; (ii) participants' knowledge of management of their condition and access to services; and (iii) participants' knowledge and perceptions of the alternate condition (LF affected participants' knowledge of leprosy and vice versa) and attitudes towards integration. RESULTS: A total of 52 LF affected and 53 leprosy affected participants were interviewed from 14 SHGs. On average, leprosy affected participants were shown to have 1.8 times greater knowledge of self-care techniques, and practiced 2.5 times more frequently than LF affected participants. Only a quarter of LF affected participants had accessed a health service for their condition, compared with 94.3% of leprosy affected people accessing a service (including SHGs), at least once a week. High levels of stigma were perceived by both groups towards the alternate condition, however, the majority of LF (79%) and leprosy (94.3%) affected participants stated that they would consider attending an integrated SHG. CONCLUSIONS: LF affected participants need to increase their knowledge of self-care and access to health services. Despite stigma being a potential barrier, attitudes towards integration were positive, suggesting that the SHGs may be a good platform for LF affected people to start self-care in this area. TRIAL REGISTRATION: This is not a registered trial.

How to improve early case detection in low endemic areas with pockets of leprosy: a study of newly detected leprosy patients in Guizhou Province, People's Republic of China.

Although leprosy in China is controlled at a low endemic level, the number of new cases in Guizhou province has shown no significant decrease over the past 20 years. Guizhou remains the province with the second highest prevalence in China. The authors conducted a study in which the characteristics of newly detected leprosy cases, found between 2008 and 2012 in Guizhou, were analysed. These cases represented people from pocket areas of leprosy in a generally low endemic environment. The purpose of the study was to understand characters of newly detected cases, strong points and weakness of routine detection approaches for improving the effectiveness of early case detection in the future. The analysis considered data that was collected from a 'Leprosy Management Information' report system and also from annual statistical reports of leprosy that reflect the situation throughout the province. 1274 new patients were detected in Guizhou from 2008 to 2012. That number included 58 (4.6%) children (0-14 years old). The average age of patients at diagnosis was 42.6 ± 16.5 years. The proportion of people with WHO Grade 2 disability (WHO DG2) among new patients was 35.7% and the proportion of people with Grade 1 disability (DG1) constituted 10.1%. The average delay before diagnosis after the onset of symptoms of leprosy was 41.7 ± 49.8 months. Suspect survey was a major method by which most cases were detected. Trough this method 790 (62.0%) new patients were detected. It was also in this group that the highest proportion of people with WHO DG2 359 of 790 (45.4%) was reported. Self- reporting, diagnosis at a general skin clinic, household contact examination, and spot surveys accounted for 13.0%, 11.8%, 11.5% and 1.7% of other cases detected respectively. It was generally found that cases detected through household contact examinations were earlier cases (delay to diagnosis < 24 months = 70.7%). It was also recorded that fewer of these had WHO DG2 (12.9%). The proportion of men with WHO DG2 was higher than that of females (38.2% compared with 28.8%). The proportion of Han Chinese new cases with WHO DG2 was significantly higher than that of the main minority group (41.5% compared with 29.2%). The proportion of new cases among the main minority group who self-reported (50%) was significantly higher than those detected through other detection approaches. Detecting leprosy early in low endemic situations where pockets persist was difficult to achieve. The authors suggest that if more early patients are to be detected earlier, the quality of suspect surveys and household contact examination should be improved. Professional training and supervision might affect that result. Greater emphasis should be given to the role of general skin clinics as surveillance sites and advocacy for new health policy that will enhance the detection leprosy should be sustained.

The experiences and attitudes of people affected by leprosy who voluntarily undertake leprosy services in Nepal.

This paper is a record of the outcome of a focus group discussion in which 22 leprosy-affected self-help group facilitators related their experiences and attitudes associated with leprosy services which they voluntarily undertake. Enthusiasm to undertake leprosy services was general. The principal rewards for participation in such activities appear to have been social ascendance and self-esteem. Factors cited as being most likely to further motivate voluntary service reflected the perceived importance of personal reputation and the prestige of a clear association with Lalgadh Leprosy Services Centre.

A Delphi exercise to refine the WHO three-point disability grading system for leprosy, and to develop guidelines to promote greater accuracy and reliability of WHO disability recording.

A Delphi Exercise was undertaken with two objectives: (1) To ascertain whether operational definitions for WHO Disability Grading could be formulated by consensus. (2) To develop a set of simple guidelines based on those definitions for the guidance of health workers. Fifteen people with general expertise in prevention of disability due to leprosy were invited to participate as Delphi panel members, twelve responded positively. Eight issues that commonly cause confusion provided foci for the exercise. Operational definitions aimed at resolving those issues were developed by consensus. Simple guidelines for health workers, based on those definitions were also created and supported by consensus. This paper presents the process followed and the outcomes gained from the endeavour.

The prevention of leprosy related disability as an integral component of the government health delivery programme in Indonesia: perspectives on implementation.

This paper presents a record of three interviews with groups of Ministry of Health personnel and consultants that took place in Jakarta, Indonesia in May 2012. Those contributing to the first interview were provincial and district supervisors with responsibility for leprosy. Those contributing to the second interview were consultants, three of whom were seconded to the Ministry of Health and one was a WHO consultant. A third interview was conducted with the Head and a technical staff member of the Sub Directorate of Leprosy and Yaws Control Programme, Ministry of Health, Indonesia. Leprosy control in Indonesia had been targeted for further enquiry after it became apparent, through an earlier survey of national programme managers and consultants, that the programme had been relatively successful in integrating POD into the government health delivery programme. The perspectives of significant representatives and actors in the national programme were recorded through the interviews undertaken in Jakarta. Limitations This report does not purport to be a study of integration of leprosy services in Indonesia. The perspectives of representatives and significant actors are offered here to enhance understanding of factors that contributed to POD becoming a routine component of general health care in Indonesia. It is also declared here that no independent verification of statements was undertaken and that the effectiveness of measures taken to integrate leprosy related POD has not been independently evaluated.

The prevention of leprosy related disability as an integral component of the government health delivery programme in Myanmar.

This paper presents a record of a focus group discussion that took place in Nyapyitaw, Myanmar in December 2010. Those contributing to the focus group discussion were senior post holders in the National Leprosy Control Programme (NLCP), Myanmar. The Myanmar programme had been targeted for further enquiry after it became apparent, through an earlier survey of national programme managers and consultants, that the programme had been relatively successful in the measures taken to facilitate the integration of POD into the government health delivery programme. The experience gained by the NLCP, Myanmar was recorded and is offered here as an example of how POD can be successfully developed by a government leprosy control programme to become integral to general health delivery.

Report of the Stigma Research Workshop for the development of scientific consensus papers and field guidelines on health-related stigma, held in Amsterdam, the Netherlands from 11-14 october 2010.

Summary In concurrence with the broad body of literature published on health-related stigma, there is a need for practical field guidance to contribute to the fight against leprosy-related stigma and discrimination. To this end, much can be gained by considering the accumulated knowledge and learned from experience with different stigmatising conditions; primarily HIV/AIDS, disability, tuberculosis, and mental health. Therefore a Stigma Research Workshop was organised from 11-14 October in Amsterdam, The Netherlands. The primary aim of the workshop was to produce scientific papers and field guidelines that could be used to target actions against health-related stigma and discrimination. Keynote presentations were offered by scientists and professionals from different health domains who shared their knowledge, experiences and research findings regarding health-related stigma. Group work was subsequently conducted to work towards agreed outputs on four different themes: i.e. research priorities, measurement, interventions, and counselling. The spectrum of expertise present enabled an interdisciplinary and inter-profession sharing of knowledge and practices. This resulted in the commencement of consensus papers and field guidelines related to the four themes. An evaluation by participants concluded that the workshop had been an informative and worthwhile activity that will strengthen the fight against stigma.

Review of leprosy research evidence (2002-2009) and implications for current policy and practice.

INTRODUCTION: The ILEP Technical Commission (ITC) advises ILEP member associations on technical aspects of leprosy. A major review of research evidence in leprosy was published prior to the International Leprosy Congress in 2002. This current report updates that review based on research published between 2002-2009 and focuses on interventions for prevention, early diagnosis, chemotherapy, reactions, prevention of disability, stigma measurement and reduction and rehabilitation in leprosy. METHODS: A systematic search of electronic databases of published literature for systematic reviews, controlled trials and ongoing trials was conducted in July 2009. The search identified 13 reviews and 21 controlled trials. The data from these studies were extracted and the references cited by these studies reviewed. Each member of the ITC took responsibility to review this evidence for each of the 7 topics and prepared a report summarising the evidence and making recommendations. These findings were presented and discussed at a Forum held in London in March 2010. The report was finalised following this Forum. The evidence was graded using a standard grading system for levels of evidence. However for some topics the evidence used qualitative and other designs which do no conform to this grading but was considered relevant and appropriate.

Impacts of the diagnosis of leprosy and of visible impairments amongst people affected by leprosy in Cebu, the Philippines.

PURPOSE: To quantify the impact of the diagnosis of leprosy and of visible impairments in people affected by leprosy. SUBJECTS AND METHODS: Three interview-based questionnaires designed to measure activity limitation, participation restriction, and general self-efficacy were used to collect data from three Groups. Group 1: leprosy affected people with visible impairment, Group 2: newly diagnosed leprosy patients with no visible impairment, Group 3: patients with other skin diseases symptomatic for more than 1 month. RESULTS: One hundred and eight subjects were recruited. The subjects with visible impairments (Group 1) had higher levels of participation restriction than those with skin disease (P0.012), and participation restriction was similar between subjects in Groups 2 and 3 (P0-305). The people in Group 1 (35 subjects) also reported significantly more activity limitation compared to the people in either Group 2 (35 subjects) or Group 3 (38 subjects) (P 0-001, respectively). The subjects in Group 2 had no significant activity limitation compared with those in Group 3 (P0.338). A multivariate analysis showed that severe visible impairment was a risk factor for activity limitation (odds ratio 5.68, 95% CI: 1.09-297, P0.039) and a low level of self-efficacy (Odds ratio 6.38, 95% CI: 1.06-38.3, P0-043) among people affected by leprosy. CONCLUSION: Visible impairments affected the activities and attitudes of people affected by leprosy. However, others without visible impairment, had activity limitations, participation restrictions and levels of general self-efficacy that were similar to patients with other skin diseases. Prevention of visible impairments should be considered a key intervention for stigma reduction.

Government health workers as implementers of prevention of disability measures: an assessment of a prevention of disability project in selected counties of Guizhou Province, Peoples' Republic of China.

OBJECTIVE: The purpose of this study was to assess the effectiveness of government health workers as agents for the prevention of disability. DESIGN: A prevention of disability (POD) project for people affected by leprosy was conducted in nine counties of Guizhou Province, Peoples' Republic of China. The project was implemented by government health workers. In accordance with the principles and national criteria of the National Centre for Leprosy Control (NCLC) POD Pilot programme, 1215 people affected by leprosy were selected, followed up and assessed with the use of impairment summary forms through which essential indicators were routinely collected. RESULTS: Most improvements of disabilities occurred in the 1st year of the POD project. Fifty five people with neuritis were detected and treated with prednisolone out of 262 new patients; 47 of these improved; 1130 people completed a 3-year self-care programme; 88.5% of red eyes, 83.9% of hand ulcers and 62.8% of simple foot ulcer cases healed during that period. One hundred and ninety six people who presented with complicated ulcers were treated; of these 73 (37.2%) people presented with feet free of ulcers at the end of the project period. CONCLUSION: The POD project was a cost-effective method of preventing further disability occurrence among people affected by leprosy. Government health workers were generally able to implement and monitor the project effectively. Most of people affected by leprosy were satisfied that the improvements in their disabilities had been due to self-care. The programme had helped them to increase their confidence to implement self-care activities.

The sustainability of self-care in two counties of Guizhou Province, Peoples' Republic of China.

This paper presents the findings of a follow-up survey conducted in two rural counties of Guizhou Province, PRC where a programme to prevent disabilities amongst leprosy affected people had been conducted. An initial 3-year programme had been conducted. One year after the final evaluation of the programme, a team was deployed to conduct a survey in the area. The objective of the survey was to establish the level of adherence to self-care. It was found that 87% of the sample of people living in leprosy villages that were surveyed (n = 31) and 50% of the sample of people living in general communities (n = 50) had continued to apply self-care. Interviews with family members suggested that 18 of the 27 self-care practising subjects living in the leprosy villages received encouragement or active support from family members (9 were single people). Twenty three of the 25 self-care practising subjects living in the communities also received family support (2 were single people). Family support was a highly significant factor influencing adherence in the community (OR = 15.8, CI = 3.0 to 83) but it may not have been the primary motivating factor in the leprosy villages where single people were just as likely to have adhered to self-care than people who were living in families (OR 0.5, CI = 0.06 to 4.2). The prevalence of foot ulceration among that population was recorded but a hypothetical association between the prevalence of foot ulceration and self-care adherence could not be investigated due to insufficient data to address the potential effects of confounding variables. Thirty-eight percent of subjects who did not practice self-care presented with ulceration or foot cracks (n = 29) compared with only 25% of people who did (n = 52).

The validity and reliability of a simple semantic classification of foot posture.

INTRODUCTION: The Simple Semantic Classification (SSC) is described as a pragmatic method to assist in the assessment of the weight bearing foot. It was designed for application by therapists and technicians working in underdeveloped situations, after they have had basic orientation in foot function. OBJECTIVE: To present evidence of the validity and inter observer reliability of the SSC. METHOD: 13 physiotherapists from LEPRA India projects and 12 physical therapists functioning within the National Programme for the Elimination of Hansen's Disease (PNEH), Brazil, participated in an inter-observer exercise. Inter-observer agreement was gauged using the Kappa statistic. The results of the inter-observer exercise were dependent on observations of foot posture made from photographs. This was necessary to ensure that the procedure was standardised for participants in different countries. The method had limitations which were partly reflected in the results. RESULTS: The level of agreement between the principle investigator and Indian physiotherapists was Kappa = 058. The level of agreement between Brazilian physical therapists and the principle investigator was Kappa = 0.70. CONCLUSION: The authors opine that the results were sufficiently compelling to suggest that the Simple Semantic Classification can be used as a field method to identify people at increased risk of foot pathologies.
