Towards a toolkit for cross-neglected tropical disease morbidity and disability assessment

Prevalence of helmintic infections in Brazilian Maxakali indigenous: a repeated cross-sectional design

BACKGROUND

The prevalence of intestinal parasites is known to be high among Amerindian populations; further, there are serious problems in the healthcare of these populations in Brazil. The Maxakali, located in the northeastern region of Minas Gerais, Brazil, is an indigenous group that still preserves many of its cultural aspects. This study aimed to compare the positivity rate of schistosomiasis and soil-transmitted helminths in this ethnic group in epidemiological surveys conducted in 1972 and 2014.

METHODS

Stool parasitological examinations were performed by the Kato-Katz technique during both periods in this population. In 2014, the parasitological diagnosis was also realized with the TF-Test® technique.

RESULTS

In 1972, 270 inhabitants were examined. The positivity rates were 67.4% for Schistosoma mansoni, 72.9% for hookworms, 43.7% for Ascaris lumbricoides, and 23.7% for Trichuris trichiura. In 2014, 545 individuals were examined, and the positivity rates obtained were 45.7% for S. mansoni, 22.8% for hookworms, 0.6% for A. lumbricoides, and 2.8% for T. trichiura.

CONCLUSIONS

The comparison of the parasitological surveys conducted in 1972 and 2014, indicates that the indigenous Maxakali remained neglected by the health and indigenous protection authorities during these four decades. The infection rate observed in 2014 for schistosomiasis and hookworm remains high, considering the current epidemiological view of these diseases in the Brazilian population.

Mental health, stigma and the quality of life of people affected by neglected tropical diseases of the skin in Kasai Province, Democratic Republic of the Congo: a sex-disaggregated analysis

BACKGROUND

Worldwide, persons affected by skin Neglected Tropical Diseases (NTDs) may experience stigma and discrimination, which could lead to impaired societal functioning and poor mental wellbeing. Evidence of comorbidity of NTDs and mental health conditions is dominated by Leprosy, largely lacking in post-conflict areas, and rarely disaggregated by sex.

METHODS

This cross-sectional survey is the first to explore depression, anxiety, stigma, and quality of life amongst people affected by Lymphatic Filariasis, Buruli Ulcer, Onchocerciasis or Leprosy in the Democratic Republic of the Congo. After a census through active case identification, the survey was completed by 118 persons (response rate 94.4%).

RESULTS

In total, 58.3% of men and 80.0% of women screened positive for major depressive disorder (PHQ-9). Symptoms indicative of generalised anxiety disorder (GAD-7) were displayed by 54.8% of men and 62.2% of women. Being female, having a disability, experiencing stigma and lower physical quality of life were predictors of depression. Anxiety was predicted by age, physical quality of life, disability (for men only) and environmental quality of life (for women only).

CONCLUSIONS

Integrated, intersectoral and gender-sensitive initiatives are needed to respond to the many biopsychosocial challenges that persons affected face.

CONTEXTE

Dans le monde entier, les personnes atteintes de maladies tropicales négligées (MTN) peuvent faire l'objet d'une stigmatisation et d'une discrimination, ce qui peut entraîner une altération du fonctionnement de la société et un mauvais bien-être mental. Les preuves de la comorbidité des MTN et des troubles de la santé mentale sont dominées par la lèpre, manquent largement dans les zones post-conflit et sont rarement ventilées par sexe.

MÉTHODES UTILISÉES

Cette enquête transversale est la première à explorer la dépression, l'anxiété, la stigmatisation et la qualité de vie chez les personnes atteintes de filariose lymphatique, d'ulcère de Buruli, d'onchocercose ou de lèpre en République démocratique du Congo. Après un recensement par identification active des cas, 118 personnes ont répondu à l'enquête (taux de réponse 94,4%).

RÉSULTATS

Au total, 58,3% des hommes et 80,0% des femmes ont été dépistés positifs pour un trouble dépressif majeur (PHQ-9). Des symptômes indiquant un trouble anxieux généralisé (GAD-7) ont été observés chez 54,8 % des hommes et 62,2 % des femmes. Le fait d'être une femme, d'avoir un handicap, d'être stigmatisé et d'avoir une qualité de vie physique inférieure était un facteur prédictif de la dépression. L'anxiété était prédite par l'âge, la qualité de vie physique, le handicap (pour les hommes uniquement) et la qualité de vie environnementale (pour les femmes uniquement).

CONCLUSIONS

Des initiatives intégrées, intersectorielles et sensibles au genre sont nécessaires pour répondre aux nombreux défis biopsychosociaux auxquels sont confrontées les personnes touchées.

ANTECEDENTES

En todo el mundo, las personas afectadas por Enfermedades Tropicales Desatendidas (ETD) cutáneas pueden sufrir estigmatización y discriminación, lo que podría conducir a un deterioro del funcionamiento social y a un bienestar mental deficiente. La evidencia científica sobre la comorbilidad de las ETD y las afecciones mentales está dominada por la lepra, en general insuficiente en zonas post-conflicto y rara vez se desglosan por sexo.

MÉTODOS

Esta encuesta transversal es la primera que explora la depresión, la ansiedad, el estigma y la calidad de vida entre las personas afectadas por la filariasis linfática, la úlcera de Buruli, la oncocercosis o la lepra en la República Democrática del Congo. Tras un censo mediante identificación activa de casos, la encuesta fue completada por 118 personas (tasa de respuesta del 94,4%).

RESULTADOS

En total, el 58,3% de los hombres y el 80,0% de las mujeres arrojaron resultados positivos para el trastorno depresivo mayor (PHQ-9). El 54,8% de los hombres y el 62,2% de las mujeres presentaban síntomas indicativos de trastorno de ansiedad generalizada (TAG-7). Ser mujer, tener una discapacidad, sufrir estigmatización y una menor calidad de vida física fueron factores predictivos de la depresión. La edad, la calidad de vida física, la discapacidad (sólo en el caso de los hombres) y la calidad de vida ambiental (sólo en el caso de las mujeres) fueron factores predictivos de la ansiedad.

CONCLUSIONES

Se necesitan iniciativas integradas, intersectoriales y con perspectiva de género para responder a los numerosos retos biopsicosociales a los que se enfrentan las personas afectadas.

Evaluation of the properties of WHODAS-12 measurements in individuals with Chagas disease in Brazil

Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser-Meyer-Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.

Construction and validation of an instrument for assessing the functionality of individuals with schistosomiasis

OBJECTIVES

to construct and validate an instrument for assessing the functionality of individuals with schistosomiasis.

METHODS

methodological study, developed in three stages: 1) construction of the instrument and its association with categories of the International Classification of Functionality, which the study used to elaborate the questions; 2) validation of content, performed by judges experts in the subject; 3) application of the instrument by the test-retest technique in the population with schistosomiasis in 14 days. The study used the correlation coefficient kappa to calculate the degree of agreement between the judges kappa.

RESULTS

in its final version, the instrument consists of 27 items, 9 of which are from the Body functions component, 6 from Body structures, 4 from Activity and participation, and 8 from Environmental factors.

CONCLUSIONS

the constructed instrument has a biopsychosocial approach, considering four components of the ICF, besides presenting good validity and interobserver reliability.

Effectiveness of self-care interventions for integrated morbidity management of skin neglected tropical diseases in Anambra State, Nigeria

Background

Lymphatic filariasis (LF), Buruli ulcer (BU) and leprosy are neglected tropical diseases (NTDs) of the skin co-endemic in some communities in Nigeria. Not enough is known about the effectiveness of integrated morbidity management and disability prevention in people with these conditions. An integrated self-care intervention was carried out for people with these skin NTDs in two endemic communities of Anambra state, Nigeria. The objective of the study was to assess the effectiveness of self-care practices on costs of care, disability status and health-related quality of life.

Methods

This study utilised a quasi-experimental pre-test/post-test design to assess the effectiveness of the self-care interventions for people affected by NTDs to care for these impairments at home. Data were collected using questionnaires administered at the beginning and at the end of the intervention on monthly cost of morbidity care, and on participants’ disability status and their quality of life (QoL). Focus group discussions (FGDs) were held with both the participants and healthcare workers at follow-up.

Results

Forty-eight participants were recruited. Thirty participants (62.5%) continued the self-care interventions until the end of the project. Of those, 25 (83%) demonstrated improvement from their baseline impairment status. The mean household costs of morbidity care per participant decreased by 66% after the intervention, falling from US$157.50 at baseline to US$53.24 after 6 months of self-care (p = 0.004). The mean disability score at baseline was 22.3; this decreased to 12.5 after 6 months of self-care (p < 0.001). Among the 30 participants who continued the interventions until the end of the project, 26 (86.7%) had severe disability score (i.e. a score of 10–46) at baseline, and the number with severe disability fell to 18 (60%) of the 30 after the intervention. The mean QoL score increased from 45.7 at baseline to 57.5 at the end of the intervention (p = 0.004).

Conclusions

The 6-month self-care intervention for participants affected by BU, leprosy, or LF led to lower costs of care (including out-of-pocket costs and lost earnings due to morbidity), improved QoL scores, and reduced disability status.

Mental health and quality of life burden in Buruli ulcer disease patients in Ghana

BACKGROUND

Buruli ulcer disease (BUD) is a necrotic skin neglected tropical disease (NTD) that has both a mental and physical health impact on affected individuals. Although there is increasing evidence suggesting a strong association between neglected tropical diseases (NTDs) and mental illness, there is a relative lack of information on BUD's impact on the mental health and quality of life (QoL) of affected individuals in Ghana. This study is to assess the impact of BUD on mental health and quality of life of patients with active and past BUD infection, and their caregivers.

METHODS

We conducted a case control study in 3 BUD endemic districts in Ghana between August and November 2019. Face-to-face structured questionnaire-based interviews were conducted on BUD patients with active and past infection, as well as caregivers of BUD patients using WHO Quality of Life scale, WHO Disability Assessment Schedule, Self-Reporting Questionnaire, Buruli Ulcer Functional Limitation Score and Hospital Anxiety and Depression Scale data tools. Descriptive statistics were used to summarize the characteristics of the study participants. Participant groups were compared using student t test and chi-square (χ²) or Fisher's exact tests. Mean quality of life scores are reported with their respective 95% confidence intervals. Data was analysed using STATA statistical software.

RESULTS

Our results show that BUD patients with active and past infection, along with their caregivers, face significant levels of distress and mental health sequelae compared to controls. Depression (P = 0.003) was more common in participants with active (27%) and past BU infection (17%), compared to controls (0%). Anxiety was found in 42% (11/26) and 20% (6/29) of participants with active and past BUD infection compared to 14% (5/36) of controls. Quality of life was also significantly diminished in active BUD infection, compared to controls. In the physical health domain, mean QoL scores were 54 ± 11.1 and 56 ± 11.0 (95% CI: 49.5‒58.5 and 52.2‒59.7) respectively for participants with active infection and controls. Similarly in the psychological domain, scores were lower for active infection than controls [57.1 ± 15.2 (95% CI: 50.9‒63.2) vs 64.7 ± 11.6 (95% CI: 60.8‒68.6)]. Participants with past infection had high QoL scores in both physical [61.3 ± 13.5 (95% CI: 56.1‒66.5)] and psychological health domains [68.4 ± 14.6 (95% CI: 62.7‒74.0)].

CONCLUSIONS

BUD is associated with significant mental health distress and reduced quality of life in affected persons and their caregivers in Ghana. There is a need for integration of psychosocial interventions in the management of the disease.

An exploration of family quality of life in persons with leprosy-, lymphatic filariasis- and podoconiosis-related disabilities and their family members in Ethiopia

Background

Leprosy, podoconiosis and lymphatic filariasis (LF) may adversely affect the social, economic and psychological well-being of persons affected and their families. The objectives of this study were to assess and compare family quality of life of persons affected and their family members, explore the relationship between family quality of life and perceived stigma and activity limitations and explore what factors influence family quality of life.

Methods

A cross-sectional quantitative study was conducted in the Awi zone in Ethiopia. Persons affected and their family members were selected using purposive sampling. Three questionnaires were used: the Beach Center Family Quality of Life (FQOL) scale (range 25–125, with higher scores denoting higher family quality of life), the SARI Stigma Scale (range 0–63, with higher scores denoting higher levels of stigma) and the Screening of Activity Limitation and Safety Awareness (SALSA) scale (range 0–80, with higher scores denoting more activity limitations). Data analysis consisted of simple descriptive analysis and regression analysis.

Results

A total of 95 persons affected and 117 family members were included. The overall mean of the family quality of life score was 71.7. Persons affected had significantly higher mean family quality of life scores than family members on all domains. Female gender, a smaller family size and occupation were associated with lower family quality of life. We found a mean SARI Stigma score of 22.3 and a mean SALSA score of 37.6. There was no association between the FQOL and SARI scores or between the FQOL and SALSA scores.

Conclusions

Family quality of life is an important area to address because neglected tropical diseases often affect the whole family. It is therefore important in order to provide appropriate support for persons affected and their family members. Efforts to improve the quality of life of families in which a family member is affected by leprosy, podoconiosis or LF should give priority to women and families with a smaller family size.

Integration of Management Strategies for Skin-Related Neglected Tropical Diseases

The concept of skin neglected tropical diseases has been widely adopted into the policy and strategy of various organizations, governments, nongovernmental organizations, and health agencies. By pooling information and resources across different diseases, whose primary manifestations affect the skin, it is possible to deliver integrated surveillance and control programs and promote advocacy and reduction of disability and stigma. A further key part of the skin neglected tropical diseases program is the development and validation of training methods for front-line health workers. Networks that allow those involved in this work to share and compare expertise are being developed through various organizations.

Neglected tropical diseases and disability-what is the link?

Neglected tropical diseases (NTDs) are a diverse group of infectious conditions that vary in their epidemiology, impact and control. They are among the most common conditions globally, affecting approximately one billion people. Many NTDs have long-term consequences, such as visual and physical impairments. As a result, people with NTDs may have difficulties in carrying out activities or participating in society—in other words, NTDs can cause disabilities. Additionally, NTDs are often strongly linked to stigma and can have mental health consequences. It is therefore important to incorporate rehabilitation within NTD programmes. Rehabilitation can be conceptualized narrowly in terms of the provision of clinical services (e.g. physiotherapy and assistive devices) or, more broadly, including efforts to improve employment, overcome stigma and enhance social participation of people with disabilities. Approximately 15% of the global population has a disability, and this large group must be considered when designing NTD programmes. Improving the inclusion of people with disabilities may require adaptations to NTD programmes, such as making them physically accessible or training staff about disability awareness. Without incorporating disability within NTD programmes, the quality of life of people with NTDs will suffer and global targets for elimination and management of NTDs will not be met.

People are neglected, not diseases: the relationship between disability and neglected tropical diseases

People with disabilities and the neglected tropical diseases (NTDs) are separately receiving increased focus. In light of this positive development, and the similarities and intersections between the negative impacts experienced by both people with disabilities and people with NTDs, we believe now is the right time to focus attention on the overlap between the two. Both people with NTDs and people with disabilities experience a myriad of overlapping negative health, financial and socio-cultural consequences. Despite this, we believe that disability is not yet properly prioritised on the development agenda, and that there are multiple opportunities to make NTD programming more inclusive, to the benefit of those at this neglected intersection and beyond. There are both opportunities and need to scale up, integrate, and invest in inclusive, health system-focused NTD programming. Realisation of the Sustainable Development Goals, Universal Health Coverage, and the control and elimination of NTDs all rely on ensuring people with disabilities are not left behind.

Stigma, participation restriction and mental distress in patients affected by leprosy, cutaneous leishmaniasis and Chagas disease: a pilot study in two co-endemic regions of eastern Colombia

BACKGROUND

Leprosy, cutaneous leishmaniasis (CL) and Chagas disease (CD) are neglected tropical diseases with a high psychosocial burden (PSB). These conditions are endemic in Norte de Santander and Arauca in Colombia, but data on the related PSB are scarce. Therefore, we assessed mental distress, participation restriction and stigma among CD, CL and leprosy patients.

METHODS

In 2018, 305 leprosy, CD or CL patients were interviewed using a self-report questionnaire to assess mental distress, participation scale for participation restriction and explanatory model interview catalogue (EMIC) for stigma. Descriptive statistics and the significance of median score differences were compared.

RESULTS

Fifty percent of CD patients and 49% of leprosy patients exhibited mental distress, percentages which were significantly higher than that of CL (26%). Twenty-seven percent of leprosy patients experienced participation restriction, which was lower for CL (6%) and CD (12%). Median EMIC scores were significantly higher for leprosy patients than for CD (27%) and CL (17%) patients.

CONCLUSIONS

We found high levels of PSB among leprosy, CD and CL patients. Mental distress was highest among CD patients. Participation restriction and stigma were more prevalent in leprosy patients. Rural residence or lower educational status may impact PSB. Further investigation is needed to formulate evidence-based, holistic interventions.

The impact of leprosy on the mental wellbeing of leprosy-affected persons and their family members - a systematic review

Leprosy has long-term consequences related to impairment and stigma. This includes a major impact on mental health. This study aims to consolidate current evidence regarding the mental health impact of leprosy on affected persons and their family members. In addition, determinants influencing mental health outcomes among leprosy-affected persons and effective interventions are examined. A keyword-based search was conducted in PubMed, Web of Science, Scopus, PsycINFO, Infolep and InfoNTD; additional literature was also considered. Articles presenting primary data involving leprosy-affected persons or their family members experiencing mental conditions were included. Independent extraction of articles was executed using predefined data fields. Articles were sorted according to relevance. In total, 65 studies were included in this systematic review. Multiple psychiatric morbidities have been identified among leprosy-affected persons, including depression, anxiety disorders and suicide (attempts). Additional factors were found that may impact mental health. Moreover, studies found that demographic factors, lifestyle and disease-specific factors and stigma and discrimination impact mental health. Depressive symptoms and low self-esteem were identified among children of leprosy-affected persons. In addition, interventions were identified that could improve the mental wellbeing of leprosy patients. Depressive disorders and anxiety disorders were found to be very common among persons affected by leprosy. Feelings such as fear, shame and low self-esteem are also experienced by those affected, and their children. Further research is necessary to ensure that mental health impact is included when determining the burden of disease for leprosy, and to relieve this burden.

Validation of a cross-NTD toolkit for assessment of NTD-related morbidity and disability. A cross-cultural qualitative validation of study instruments in Colombia

Background

Many neglected tropical diseases (NTDs) are not fatal, but they are disabling, disfiguring and stigmatizing. More accurate data on these aspects would benefit planning, monitoring and evaluation of interventions, as well as provision of appropriate services for the often life-long consequences. In 2015, a cross-NTD toolkit was developed, consisting of a variety of existing questionnaires to measure morbidity, disability and health-related quality of life. The toolkit covers the domains of the International Classification of Functioning, Disability and Health (ICF) framework. These tools have been developed in a source country, however, it was intended for the cross-NTD toolkit to be applicable across NTDs in many countries with different cultures and languages in order to generate universally comparative data. Therefore; the present study aimed to validate several tools of the toolkit among people affected by leprosy or leishmaniasis in the cultural settings of Cartagena and Cúcuta, Colombia.

Methodology

This study aimed to validate the following tools among 55 participants between 18–85 years old, affected by leprosy and leishmaniasis: (I) Clinical Profile, (II) Self-Reporting Questionnaire (SRQ), (III) WHO Quality of Life assessment-abbreviated version (WHOQOL-BREF), and (IV) WHO Quality of Life assessment-Disability (WHOQOL-DIS). The tools were administered during face-to-face interviews and were followed by open questions about the respondents’ thoughts on format of the tool and the understanding, relevance and acceptability of the items. The tools were validated using a qualitative method approach based on the framework for cultural equivalence, measured by the cultural, item, semantic and operational equivalences.

Results

The Clinical Profile was seen as acceptable and relevant, only the semantic equivalence was not as satisfying and needs a few adaptations. The SRQ was very well understood and shows to reach the equivalences for the population of Colombia without any additional changes. Several items of the WHOQOL-BREF and the WHOQOL-DIS were not well understood and changes are recommended due to semantic difficulties. Operational equivalence of both questionnaires was not as desired in relation to the used response scales. The participants shared that the tools are relevant and important for their particular situation.

Conclusions/Significance

The SRQ is found to be a valid tool for Colombia and can be included in the cross-NTD toolkit. The Clinical Profile, WHOQOL-BREF & WHOQOL-DIS need changes and retesting among Colombian people affected by an NTD. The toolkit as a whole is seen as useful to show the effects leprosy and leishmaniasis have on the participants. This cultural validation will contribute to a universally applicable cross-NTD toolkit.

Temporal trend of leprosy in a region of high endemicity in the Brazilian Northeast

OBJECTIVE

to analyze the temporal trend and epidemiological patterns of leprosy indicators in Sobral, a municipality countryside of the state of Ceará, from 2001 to 2016.

METHOD

a time series study based on data from the Department of Informatics of the Unified Health System. The time trend analysis was performed using the join point regression model.

RESULTS

There were 2,220 new cases of leprosy in Sobral from 2001 to 2016. Of these, 158 (7.2%) in children younger than 15 years of age, the proportion of new male cases was 52.8% (1,162), cases with grade 2 were 7.0% (156), and proportion of cases diagnosed by contact examination 5.7% (126).

FINAL CONSIDERATIONS

leprosy remains hyperendemic in adults and children, demonstrating the character of neglected disease. Analysis of the temporal trend allowed to verify that the instability in the detection coefficients, reflect operational problems in the organization of the services.

Neglected Tropical Diseases and Mental Health: Progress, Partnerships, and Integration

Neglected tropical diseases (NTDs) are increasingly recognised as major drivers of psychosocial morbidity in affected individuals and their caregivers. Nevertheless, there has remained a lack of prioritisation at the policy level of some of the most stigmatising and chronic NTDs, with subsequent under-representation within NTD programmes. In response, the Neglected Tropical Disease/Non-Governmental Organization/Network (NNN) has established a Mental Wellbeing and Stigma Task Group (MWS) to address these issues through a comprehensive research agenda. In our article, we highlight the progress in understanding the scope of the mental health impact of NTDs and the innovative practice emerging in this area. Finally, we examine opportunities for integration of mental and physical health for individuals with NTDs.

Uncharted territory of the epidemiological burden of cutaneous leishmaniasis in sub-Saharan Africa-A systematic review

INTRODUCTION

Cutaneous leishmaniasis (CL) is the most frequent form of leishmaniasis, with 0.7 to 1.2 million cases per year globally. However, the burden of CL is poorly documented in some regions. We carried out this review to synthesize knowledge on the epidemiological burden of CL in sub-Saharan Africa.

METHODS

We systematically searched PubMed, CABI Global health, Africa Index Medicus databases for publications on CL and its burden. There were no restrictions on language/publication date. Case series with less than ten patients, species identification studies, reviews, non-human, and non-CL focused studies were excluded. Findings were extracted and described. The review was conducted following PRISMA guidelines; the protocol was registered in PROSPERO (42016036272).

RESULTS

From 289 identified records, 54 met eligibility criteria and were included in the synthesis. CL was reported from 13 of the 48 sub-Saharan African countries (3 eastern, nine western and one from southern Africa). More than half of the records (30/54; 56%) were from western Africa, notably Senegal, Burkina Faso and Mali. All studies were observational: 29 were descriptive case series (total 13,257 cases), and 24 followed a cross-sectional design. The majority (78%) of the studies were carried out before the year 2000. Forty-two studies mentioned the parasite species, but was either assumed or attributed on the historical account. Regional differences in clinical manifestations were reported. We found high variability across methodologies, leading to difficulties to compare or combine data. The prevalence in hospital settings among suspected cases ranged between 0.1 and 14.2%. At the community level, CL prevalence varied widely between studies. Outbreaks of thousands of cases occurred in Ethiopia, Ghana, and Sudan. Polymorphism of CL in HIV-infected people is a concern. Key information gaps in CL burden here include population-based CL prevalence/incidence, risk factors, and its socio-economic burden.

CONCLUSION

The evidence on CL epidemiology in sub-Saharan Africa is scanty. The CL frequency and severity are poorly identified. There is a need for population-based studies to define the CL burden better. Endemic countries should consider research and action to improve burden estimation and essential control measures including diagnosis and treatment capacity.

The Skin-A Common Pathway for Integrating Diagnosis and Management of NTDs

Many of the neglected tropical diseases (NTDs) have major skin manifestations. These skin-related NTDs or ‘skin NTDs’ cause significant morbidity and economic hardship in some of the poorest communities worldwide. We draw attention to the collective burden of skin disease and suggest that the skin be used as a platform for the integration of control activities for NTDs. The opportunities for integration are numerous, ranging from diagnosis and disease mapping to mass drug administration and morbidity management. The dermatology community has an important role to play, and will be expected to support research and control activities globally.

A Delphi consultation to assess indicators of readiness to provide quality health facility-based lymphoedema management services

BACKGROUND

The World Health Organization (WHO) in collaboration with partners is developing a toolkit of resources to guide lymphatic filariasis (LF) morbidity management and disability prevention (MMDP) implementation and evaluation. Direct health facility inspection is the preferred method for documenting the readiness of a country programme to provide quality lymphoedema management services, one of the three MMDP criteria used to demonstrate the elimination of LF as a public health problem.

METHODOLOGY/PRINCIPAL FINDINGS

As component of tool development, a Delphi consultation was implemented to gain consensus on six proposed domains and fourteen proposed tracer indicators to measure national programme readiness to provide quality health facility-based lymphoedema management services. A seven-point Likert-type scale was used to rank the importance of proposed domains and tracer indicators. Consensus for inclusion of the indicator was defined a priori as 70% or more of respondents ranking the proposed indicator in the top three tiers (5-7). Purposive sampling was used to select 43 representative experts including country representatives, programme implementers, and technical experts. A 55.8% response rate (n = 24) was achieved for the survey. Analysis of the responses demonstrated that consensus for inclusion had been reached for all proposed domains including trained staff (mean = 6.9, standard deviation (SD) = 0.34), case management and education materials (mean = 6.1, SD = 0.65), water infrastructure (mean = 6.3, SD = 0.81), medicines and commodities (mean = 6.3, SD = 0.69), patient tracking system (mean = 6.3, SD = 0.85), and staff knowledge (mean = 6.5, SD = 0.66).

SIGNIFICANCE

The Delphi consultation provided an efficient and structured method for gaining consensus among lymphatic filariasis experts around key lymphoedema management quality indicators. The results from this analysis were used to refine the indicators included within the direct inspection protocol tool to ensure its ability to assess health facility readiness to provide quality lymphoedema management services.

Psychosocial burden of localised cutaneous Leishmaniasis: a scoping review

Background

Cutaneous Leishmaniasis (CL) is a parasitic skin disease, linked to poverty, and belonging to the group of Neglected Tropical Diseases. Depending on the severity, the type of lesions or scars, and the context, CL can lead to self- and social stigma influencing the quality of life and psychological well-being of the patient. This dimension is, however, little documented for the most common, localized form of cutaneous leishmaniasis (LCL).

We aimed to describe the current knowledge on the psychological burden and the stigma related to LCL.

Methods

The population of interest for this scoping review are patients or their relatives with localized LCL or related scars.

We searched the electronic databases PubMed, Web of Knowledge, PsycINFO, POPLINE, Cochrane Library, Science Direct, Global Health, and LILACS, for articles written in Arabic, English, French, Dutch, Portuguese, or Spanish, and published until the end of August 2017.

Results

From 2485 initial records, 15 papers met our inclusion criteria. Dermatology life quality index was the most frequent used scale to assess LCL psychological impact in quantitative studies. Six qualitative studies used individual interviews and/or focus groups discussions to explore the psychological and/or the social burden of this disease. Quantitative assessments using standard scales as well as qualitative research asserts that LCL is a source of psychological suffering, stigmatization, and decreased quality of life (QoL).

Conclusion

Most studies showed that LCL has a significant negative effect on the QoL and mental health. However, the fact that the psychosocial burden generated by LCL is time-dependent makes it hard to measure. We recommend to develop a more specific and validated assessment scale to appreciate the full burden of this disease and enhance comparability of findings.

Opportunities for Integrated Control of Neglected Tropical Diseases That Affect the Skin

Many neglected tropical diseases (NTDs) affect the skin, causing considerable disability, stigma, and exacerbation of poverty. However, there has been relatively little investment into laboratory research, epidemiology, diagnostic tools or management strategies to control tropical skin disease. Integration may advance the control of skin disease across a range of domains, including mapping, diagnosis, clinical management, and community control measures such as mass drug administration. Examples of successful integration strategies include programs targeting scabies, impetigo, yaws, and diseases causing lymphoedema. Future strategies should build on these experiences and the experience of integration of other NTDs, strengthen existing health systems, and contribute toward the attainment of Universal Health Coverage. Strong partnerships and political support and will be necessary to achieve these goals.
