Cutaneous leishmaniasis in Guatemala: people's knowledge, concepts and practices

"Cheaper and better": Societal cost savings and budget impact of changing from systemic to intralesional pentavalent antimonials as the first-line treatment for cutaneous leishmaniasis in Bolivia

Introduction

Cutaneous leishmaniasis (CL), endemic in Bolivia, mostly affects poor people in rainforest areas. The current first-line treatment consists of systemic pentavalent antimonials (SPA) for 20 days and is paid for by the Ministry of Health (MoH). Long periods of drug shortages and a lack of safe conditions to deliver treatment are challenges to implementation. Intralesional pentavalent antimonials (ILPA) are an alternative to SPA. This study aims to compare the cost of ILPA and SPA, and to estimate the health and economic impacts of changing the first-line treatment for CL in a Bolivian endemic area.

Methods

The cost-per-patient treated was estimated for SPA and ILPA from the perspectives of the MoH and society. The quantity and unit costs of medications, staff time, transportation and loss of production were obtained through a health facility survey (N = 12), official documents and key informants. A one-way sensitivity analysis was conducted on key parameters to evaluate the robustness of the results. The annual number of patients treated and the budget impact of switching to ILPA as the first-line treatment were estimated under different scenarios of increasing treatment utilization. Costs were reported in 2017 international dollars (1 INT$ = 3.10 BOB).

Results

Treating CL using ILPA was associated with a cost-saving of $248 per-patient-treated from the MoH perspective, and $688 per-patient-treated from the societal perspective. Switching first-line treatment to ILPA while maintaining the current budget would allow two-and-a-half times the current number of patients to be treated. ILPA remained cost-saving compared to SPA in the sensitivity analysis.

Conclusions

The results of this study support a shift to ILPA as the first-line treatment for CL in Bolivia and possibly in other South American countries.

Cutaneous leishmaniasis is a neglected tropical disease which causes chronic skin ulcers and disproportionally affects the poorest of the poor. The current first-line treatment, based on systemic pentavalent antimonials, is quite toxic for patients but also expensive for governments and patients. Given limited budgets, national decision-makers need to know not only the efficacy of alternative treatments, but also how to maximise the population health impact of available resources. To strengthen the evidence base for the scale-up of effective NTD interventions in the era of universal health coverage, we conducted cost-effectiveness analyses and estimations of population-level impact of the implementation of intralesional pentavalent antimonials as first-line treatment for cutaneous leishmaniasis using realistic scenarios. Our results demonstrate that changing first-line treatment would have considerable economic advantages for patients due to the shorter treatment duration (savings in terms of food, accommodation, transport, productivity loss); and for the national control program due to the reduced use of drugs and staff time. In addition, this change would offer better value for money given that two-and-a-half times the current number of patients could be treated with the current expenditure level if intralesional pentavalent antimonials were offered to eligible patients.

Cutaneous leishmaniasis a neglected tropical disease: community knowledge, attitude and practices in an endemic area, Northwest Ethiopia

Background

Cutaneous leishmaniasis is one of the neglected tropical diseases in the Ethiopian highlands and studies on assessment of knowledge, attitude and practice of the community in endemic areas are scanty. The study aimed to assess the knowledge, attitude towards cutaneous leishmaniasis and treatment seeking practices in people living in the endemic highlands areas in the Northwest, Ethiopia and to provide evidence-based information to guide development of appropriate interventions to reduce the impact of cutaneous leishmaniasis on communities.

Methods

Quantitative cross-sectional study was conducted in cutaneous leishmaniasis endemic districts (woredas) using a semi structured questionnaire. Households were randomly selected according to probability proportional to size of households in each enumeration area. Systematic random sampling of eligible households was based on the number of households recorded during listing of households. Descriptive statistics was used to describe numerical data, organise and summarise the data in a manner that gave meaning to the numerical form. Frequency tables were used to show descriptive analysis and regression analysis was used to determine correlation between variables.

Results

Majority of respondents 321(78.7%) lived in rural areas, age ranged between 18 and 85 years and most were farmers. Illiteracy was high (47.6%) among respondents and majority 358(87.8%) had seen patients with CL. Less than quarter (21.6%) had heard about sand flies and knowledge on the peak transmission period was low (46.3%). About 192 (47.1%) of the respondents indicated disfiguring lesions were the major clinical presentations, less than half 55(27.5%) of urban residents believed CL was treatable compared to 145(72.5%) of rural residents (P < 0.001). Traditional medicines were indicated as best treatment option by 209(51.2%) compared to 114(27.9%) for modern treatment. Major factors influencing treatment options included accessibility to treatment facilities, distance and short duration of treatment. Participants expressed negative experiential attitude and perceived control towards modern treatment because of inaccessibility and distance from where modern treatment is provided.

Conclusion

Priority should be given to primary prevention and appropriate awareness campaigns on lesion recognition. Information on modern treatment should be intensified.

Leishmaniasis patients' pilgrimage to access health care in rural Bolivia: a qualitative study using human rights to health approach

BACKGROUND

Leishmaniasis is a neglected tropical disease endemic in Bolivia that disproportionately affects people with little social and political capital. Although the treatment is provided free of charge by the Bolivian government, there is an under-utilization of treatments in relation to the estimated affected population. This study explores the experiences of patients with leishmaniasis and the challenges faced when searching for diagnosis and treatment in Bolivia using a human rights approach.

METHODS

We conducted open-ended interviews with 14 participants diagnosed with leishmaniasis. The qualitative data were analysed using thematic analysis and were interpreted under a human rights approach to health care.

RESULTS

Four themes emerged during data analysis: (1) the decision for seeking a cure takes time; (2) the severity of symptoms and disruption of functioning drives the search for Western medicine; (3) the therapeutic journey between Western and traditional medicine; and (4) accessibility barriers to receive adequate medical treatment. This study showed that access to health care limitations were the most important factors that prevented patients from receiving timely diagnosis and treatment. Cultural factors played a secondary role in their decision to seek medical care.

CONCLUSIONS

Accessibility barriers resulted in a large pilgrimage between public health care and traditional medicinal treatments for patients with leishmaniasis. This pilgrimage and the related costs are important factors that determine the decision to seek health care. This study contributes to the understanding of the under-utilisation problems of medical services in leishmaniasis and other similar diseases in remote and poor populations.

How cutaneous leishmaniasis and treatment impacts in the patients' lives: A cross-sectional study

Background

Until now, few studies have evaluated the effect of cutaneous leishmaniasis (CL) on patients' quality of life, and none have used a specific instrument to measure this effect. The objective of this study was to identify factors that may be associated with the high impact of CL and to assess patients’ satisfaction with treatment and health services by utilizing a disease-specific questionnaire.

Methodology

Between December 2015 and May 2017, 100 patients with localized cutaneous leishmaniasis were interviewed at a leishmaniasis referral center in Brazil. Data were collected by two questionnaires. One questionnaire compiled the sociodemographic, economic, and clinical information related to the disease. The second questionnaire was the Cutaneous Leishmaniasis Impact Questionnaire (CLIQ), which consisted of two subscales that measured 1) the general impact of CL and 2) patients’ perceptions of treatment and health services. The median scores from each of these two subscales were used to dichotomize the dependent variables. Risk factors for the high impact of CL and for low patient satisfaction with treatment and health services were analyzed with a logistic regression analysis.

Results

The chance of higher impact of CL was increased in patients with the presence of comorbidities (OR: 3.9; CI 1.25–12.36), in those with absences from work (OR: 12.0; CI 3.78–42.55), in those who relied on public transportation by a municipal bus (OR: 5.8; CI 1.27–26.77), and in those who had illness-related expenses greater than U$137 (OR: 3.5; CI 1.17–10.24). The chance of patient dissatisfaction with treatment and health services increased with higher education (OR: 5.0; CI 1.19–21.03) and with illness-related expenses exceeding U$137 (OR: 4.64; CI 1.49–14.48). Once the sample was non-probabilistic, findings are not representative of CL patients in general.

Conclusions

CL and its treatment have a negative impact on patients’ quality of life. Considering these effects during public health planning may help patients to confront the disease.

"The mosquitoes that destroy your face". Social impact of Cutaneous Leishmaniasis in South-eastern Morocco, A qualitative study

Objective

To document the psychosocial burden of Cutaneous Leishmaniasis (CL) in rural communities in Southeastern Morocco.

Method

Between March and April 2015, we conducted qualitative research in communities exposed to Leishmania major or L. tropica in Errachidia and Tinghir provinces. Twenty-eight focus groups discussions (FGDs) were realized, with a stratification by gender and tradition of medicine (users of folk versus professional medicine). Data were analyzed using content analysis.

Results

This rural population most exposed to CL in Morocco lacks access to health care in general and clearly points out there are other major public health issues that need to be resolved. Nonetheless, respondents consider the impact of CL lesions and scars as important and similar to that of burn scar tissue. Young women with CL scars in the face are stigmatized and will often be rejected for marriage in these communities. People usually try a long list of folk remedies on the active lesions, but none was felt adequate. There was a clear demand for better treatment as well as for treatment of the scars.

Conclusions

The psycho-social impact of CL due to L.major and L.tropica is substantial, especially for young single women with facial scars. These generate social and self-stigma and diminish their marriage prospects. CL is well known, but not considered as a major health priority by these poor rural communities in South-eastern Morocco where gender discrimination is still an issue and access to basic health care is as neglected as CL. Early CL diagnosis and new treatment options with better skin outcomes are urgently needed.

Cutaneous leishmaniasis: knowledge, attitude and practices of the inhabitants of the Kani forest tribal settlements of Tiruvananthapuram district, Kerala, India

Cutaneous leishmaniasis (CL) is reported among Kani tribes in forest settlements of Tiruvananthapuram district, Kerala, India. Epidemiological investigations are ongoing and 27 histopathologically confirmed cases of CL have been reported from five settlements indicating transmission of disease within settlements. One of the priorities for control/prevention of CL is to create awareness among the community and ensure optimal utilization of interventions. First step in this direction would be to carry out a situation analysis on prevailing knowledge, attitude and practice (KAP) of inhabitants. A study among 103 respondents from 10 Kani tribal settlements showed that though 39.8% of respondents recognized pictures of CL shown to them, but did not have any lay perceptions. There was absolutely no awareness on vector, transmission, risk factors and control measures. The role of sandflies in CL causation was not known to the residents and this prevented them from using any personal protection and adhering to control measures which in turn pose risk of spread of infection within settlements and to newer areas. CL has emerged as a challenging infection in this area and an urgent need for designing appropriate preventive measures and health education strategies is addressed in this article.

Some sociological aspects of cutaneous leishmaniasis in patients attending a tertiary referral centre in Colombo, Sri Lanka

Over 1800 clinically suspected cases of cutaneous leishmaniasis have been referred to the Department of Parasitology, Faculty of Medicine, Colombo, Sri Lanka for investigation since 2001. This study analyses some sociological aspects of 120 patients with laboratory confirmed cutaneous leishmaniasis. This information is important to design and implement control programmes. The disease was predominant among males. In females lesions occurred mainly on the face, while in men they were seen mainly on the limbs. Immediate medical advice was sought by 13% of the population; the others sought treatment when the skin lesion grew or failed to heal. Females delayed seeking treatment as they probably misinterpreted the lesion as a pimple. Only 39% were referred to a Consultant Dermatologist by a medical officer during the first visit. The mean duration of time from the detection of the lesion to referral was approximately eight months. Psychologically, the presence of the lesion affected less than 20% of individuals. Costs related to treatment were relatively low in Sri Lanka. Late presentation and diagnostic delay was related to lack of awareness. Educational programmes should be carried out, aimed both at health care workers and the community to ensure early diagnosis and treatment for cutaneous leishmaniasis.

Mucocutaneous leishmaniasis: knowledge, attitudes, and practices among paraguayan communities, patients, and health professionals

Cutaneous leishmaniasis (CL) and mucocutaneous leishmaniasis (MCL) due to Leishmania (V.) braziliensis are endemic in Paraguay. We performed a series of knowledge, attitudes, and practice (KAP) surveys simultaneously with individuals in endemic communities in San Pedro department (n = 463), health professionals (n = 25), and patients (n = 25). Results showed that communities were exposed to high risk factors for transmission of L. braziliensis. In logistic regression analysis, age was the only factor independently associated with having seen a CL/MCL lesion (P = 0.002). The pervasive attitude in communities was that CL was not a problem. Treatment seeking was often delayed, partly due to secondary costs, and inappropriate remedies were applied. Several important cost-effective measures are indicated that may improve control of CL. Community awareness could be enhanced through existing community structures. Free supply of specific drugs should continue but ancillary support could be considered. Health professionals require routine and standardised provision of diagnosis and treatment algorithms for CL and MCL. During treatment, all patients could be given simple information to increase awareness in the community.
