Validation of a Simple Instrument of Fast Application to Track Disability in Leprosy Patients / Validação de um instrumento simples e de aplicação rápida para rastrear incapacidade em pacientes com hanseníase

Abstract Objective To evaluate a simple and fast diagnostic instrument to be used by any health professional to track the disability presented by leprosy patients. Method Validation study of a diagnostic test performed in a sample of 156 leprosy patients to track functional disability through the shortened disabilities of arm, shoulder, and hand (QuickDASH) questionnaire. The simplified neurological assessment proposed by the World Health Organization was used as a reference. A receiver operating characteristic (ROC) curve was constructed to determine the cutoff point of QuickDASH that best discriminated patients with functional disability caused by leprosy. Results We identified 86 (55.5%) patients with functional disability by simplified neurological evaluation. The performance of the QuickDASH instrument showed that, at a cut-off point of 30 points, the sensitivity and specificity were 72.1% and 68.1% (accuracy of 70.3%), respectively, to identify functional disability, with a positive predictive value of 73.8%. Conclusion The QuickDASH instrument showed good accuracy to track functional disability in leprosy patients, and it may be useful in clinical practice of primary and general outpatient care, with the goal of identifying patients who need specialized reference for the prevention and treatment of this condition.

Functional activity limitation of leprosy cases in an endemic area in Indonesia and recommendations for integrated participation program in society.

BACKGROUND: Leprosy continues to be a health problem in Indonesia, with incidence reaching over 10,000 new cases by 2021. Leprosy-related disabilities cause limitation of patients' activity and participation in social activities. To date, no studies have been conducted in Indonesia which investigates disability in terms of bodily function, structure impairment, limitations in performing daily activities, and restrictions in participation in social activities in leprosy patients. This study is aimed to determine the demographic and clinical characteristics that might affect functional activity limitations of leprosy patients in endemic areas in Indonesia. METHODS AND FINDINGS: A cross-sectional study was conducted on 267 retrospectively-diagnosed cases of leprosy. The Screening of Activity Limitation and Safety Awareness (SALSA) scale was used to measure functional activity limitation, which comprises five domains: vision, mobility, self-care, work with hands, and dexterity. Differences among variables were evaluated using Kruskal-Wallis and Mann-Whitney test. The mean age of participants was 51.89±13.66 years, the majority of which were men (62.5%), uneducated (48.3%), and classified as type 2 in the World Health Organization (WHO) disability grading for hands and feet (66.3% and 68.2%, respectively). Assessment using the SALSA Scale showed 28.5% of subjects were without limitation, 43.8% with mild limitation, 13.5% with moderate limitation, 9.4% with severe limitation, and 4.9% with extreme limitation. Significant differences in the total SALSA Scale were found between age groups (p = 0.014), educational level (p = 0.005), occupation (p<0.001), and WHO disability grades (p<0.001). Multivariate analysis showed that the most significant factor influencing the total score of SALSA was disability grading for feet (score = 0.31, p <0.001) followed by occupational status, disability grading for eyes, and age. Limitation of functional activity was significantly correlated to becoming unemployed with the odds 2.59. CONCLUSION: People affected by leprosy are prone to have functional activity limitation, especially the elderly, uneducated, unemployed and those with multiple disabilities. If they can overcome their barriers in functional activities, they will have better occupational opportunities.

Minimally invasive sampling to identify leprosy patients with a high bacterial burden in the Union of the Comoros.

The World Health Organization (WHO) endorsed diagnosis of leprosy (also known as Hansen's disease) entirely based on clinical cardinal signs, without microbiological confirmation, which may lead to late or misdiagnosis. The use of slit skin smears is variable, but lacks sensitivity. In 2017-2018 during the ComLep study, on the island of Anjouan (Union of the Comoros; High priority country according to WHO, 310 patients were diagnosed with leprosy (paucibacillary = 159; multibacillary = 151), of whom 263 were sampled for a skin biopsy and fingerstick blood, and 260 for a minimally-invasive nasal swab. In 74.5% of all skin biopsies and in 15.4% of all nasal swabs, M. leprae DNA was detected. In 63.1% of fingerstick blood samples, M. leprae specific antibodies were detected with the quantitative αPGL-I test. Results show a strong correlation of αPGL-I IgM levels in fingerstick blood and RLEP-qPCR positivity of nasal swabs, with the M. leprae bacterial load measured by RLEP-qPCR of skin biopsies. Patients with a high bacterial load (≥50,000 bacilli in a skin biopsy) can be identified with combination of counting lesions and the αPGL-I test. To our knowledge, this is the first study that compared αPGL-I IgM levels in fingerstick blood with the bacterial load determined by RLEP-qPCR in skin biopsies of leprosy patients. The demonstrated potential of minimally invasive sampling such as fingerstick blood samples to identify high bacterial load persons likely to be accountable for the ongoing transmission, merits further evaluation in follow-up studies.

Retraso en el diagnóstico como factor pronóstico de discapacidad en pacientes con lepra en Paraguay: estudio de casos y controles / Delay in diagnosis as a prognostic factor for disability in patients with leprosy in Paraguay: case and control study

INTRODUCCIÓN: La lepra, una infección crónica, es una de las mayores causas de discapacidad prevenible. El inicio temprano del tratamiento previene el desarrollo de discapacidad. OBJETIVO: Identificar los factores pronóstico de discapacidad en individuos con lepra multibacilar y paucibacilar que culminaron el tratamiento farmacológico entre el 2011 y 2017 en Paraguay. PACIENTES Y MÉTODOS: Se realizó un estudio de casos y controles, con 34 pacientes, 9 casos, 25 controles. Los casos fueron pacientes con discapacidad Grado 1 que presentaban falta de sensibilidad en miembros inferiores o superiores, y los de Grado 2, lagoftalmos, rigidez, ulceraciones, garra pasiva, garra activa. Los controles no presentaron discapacidad. RESULTADOS: La edad media de los pacientes fue 53 ± 15,2 años, el 55,9% fue de sexo masculino y 58,9% tenía educación primaria o no tenía educación formal. El 58,8% de los pacientes presentó lepra multibacilar; y el 64,7% fue diagnosticado tras consultar con dos o más médicos. Retraso en el diagnóstico mayor a un año fue significativamente (p = 0,047) mayor en los casos que en los controles (77,8 vs 12%; OR: 7,44; IC95%: 1,02-67,86). CONCLUSIÓN: El retraso en el diagnóstico mayor a un año es un factor pronóstico de discapacidad.

BACKGROUND: Leprosy, a chronic infectious disease, is one of the major causes of preventable disability. Early treatment prevents neurological damage and disability. AIM: To identify prognostic factors of disability in individuals with multibacillary and paucibacillary leprosy who completed a drug treatment between 2011 and 2017 in Paraguay. METHODS: A case-control study was carried out on 34 patients, of them 9 were cases and 25 controls. Cases were those patients with Grade 1, presented lack of sensation in lower or upper limbs, and those of Grade 2 lagophthalmos, rigidity, visible deformity ulcerations, passive claw, active claw. Controls had no disabilities. RESULTS: Mean age of the patients was 53 ± 15.2 years, 55.9% were male, and 58.9% had primary education or no formal education. Multibacillary leprosy was found in 58.8% of patients; and 64.7% were diagnosed after consulting with two or more physicians. Diagnosis delay of more than one year was significantly (p = 0.047) greater in the cases than in the controls (77.8% vs 12%; OR: 7.44; 95% CI: 1.02-67.86). CONCLUSION: In this study, a diagnosis delay of more than one year is a prognostic factor for disability.

Mapeamento das incapacidades cinésio-funcionais de acordo com a CIF em pessoas diagnosticadas com hanseníase / Mapping of functional movement related disabilities based on the ICF model in persons with leprosy

As sequelas da hanseníase interferem no bem-estar físico, na vida pessoal e socioeconômica. Devido a essa complexidade, fica difícil relatar objetivamente a abrangência do impacto da hanseníase, porém, o modelo de Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) surgiu para classificar as condições de doença e suas consequências biopsicossociais, facilitando o diagnóstico clínico funcional de uma maneira mais realística, além da esfera biomédica. O objetivo deste estudo foi mapear as incapacidades cinésio-funcionais de pessoas com hanseníase utilizando a CIF. Trata-se de um estudo transversal, com amostra composta por pessoas com hanseníase, recrutadas no Centro de Especialidades Médicas de Aracaju e Hospital Universitário. Para coleta de dados foram utilizadas avaliações padronizadas e validadas, representando cada domínio da CIF. A análise foi descritiva e as disfunções, que foram prevalentes em 5% dos participantes, foram selecionadas como relevantes. Participaram 29 voluntários, 44,9 (±13,72) anos, 60% sexo masculino. As incapacidades funcionais mais presentes foram: 1) Estrutura do corpo - "Estrutura das áreas da pele - s810" com 78%; 2) Função do corpo - "Função tátil - b265" e "Funções relacionadas a força muscular - b730" com 100% de presença; 3) Atividade - "Levantar e carregar objetos - d430" e "Andar - d450" apresentaram limitação em 100% dos participantes; 4) Participação "Recreação e Lazer - d920" foi observada em 89% dos participantes; 5) Impacto ambiental - "Serviços, sistemas e políticas de saúde - e580" em 56% dos participantes e nos fatores pessoais o estigma com 100% de presença. Este estudo determinou quais aspectos biopsicossociais são os mais relevantes em pessoas com hanseníase e os seus resultados podem ser usados como planejamento de prevenção e tratamento dessa doença.

Leprosy sequelae interfere with physical, personal and socioeconomic life. Due to this complexity, it is difficult to objectively report the extent of the impact of leprosy; however, the International Classification of Function, Disability and Health (ICF) model classifies disease clinical conditions and their biopsychosocial consequences, facilitating a more realistic functional clinical diagnosis of leprosy, beyond the biomedical sphere. The objective of this study was to map the functional movement related disabilities of people with leprosy using the ICF. This is a cross-sectional study, with a sample composed of people with leprosy, recruited at the Aracaju Medical Specialty Center and University Hospital. For data collection, standardized and validated evaluations were used, representing each ICF domain. The analysis was descriptive, and the dysfunctions that were prevalent in 5% of the participants were selected as relevant. Twenty-nine volunteers participated, 44.9 (± 13.72) years, 60% male. The most present functional disabilities were: 1) Structure of the body - "Structure of the skin areas - s810" with 78%; 2) Body function - "Tactile function - b265" and "Functions related to muscular strength - b730" with 100% presence; 3) Activity - "Lifting and loading objects - d430" and "Floor - d450" presented limitation in 100% of participants; 4) Participation "Recreation and Leisure - d920" was observed in 89% of participants; 5) Environmental impact - "Health services, systems and policies - e580" in 56% of the participants and in the personal factors the stigma with 100% presence. This study determined which biopsychosocial aspects are most relevant in people with leprosy and its results can be used as planning for the prevention and treatment of this disease. (AU)

Activity limitation and social participation restriction among leprosy patients in Boru Meda Hospital, Amhara Region, Ethiopia.

BACKGROUND: Although Ethiopia eliminated leprosy as public health problem 20 years ago, still more than 3000 new cases are reported annually. Leprosy related disability affects patients' day to day physical activities and their participation in social activities. Assessing the degree of activity limitation and social participation is recommended to show disability and assess the efficacy of rehabilitation efforts. METHODOLOGY AND PRINCIPAL FINDING: A hospital based cross sectional study was conducted among a total of 305 leprosy patients. Data were collected by face to face interview using Screening of Activity Limitation and Safety Awareness (SALSA) scale and participation scale. The analysis was done with SPSS version 25. Descriptive statistics was done and then binary logistic regression was used to identify factors associated with activity limitation as well as participation limitation. Most patients (219, 71.8%) had activity limitation; 41 (13.4%) with severe and 25 (8.2%) with extreme limitations. More than half of patients (168, 55.1%) were suffering from participation restriction; with 43 (14.1%) having severe restriction and 30 (9.8%) extreme restriction. Older age, low educational status, distance from treatment center, time of treatment and higher Eye, Hand, Foot disability score were associated with activity limitation. Similarly, older age, low educational status and being unmarried were significantly associated with participation restriction. CONCLUSION: This study revealed that activity limitation and participation restriction are common among leprosy patients. Earlier diagnosis and improved rehabilitative services may help to decrease activity limitation, whereas community rehabilitation may improve social participation. The old and centralized leprosy rehabilitation services need to be decentralized and backed with modern equipment and trained staffs.

Disability progression among leprosy patients released from treatment: a survival analysis.

BACKGROUND: Leprosy can be cured, but physical disability (PD) as a result of the infection can progress in the post-release from treatment phase. This study evaluated the likelihood of, and factors associated with, the progression of the PD grade post-release from treatment among leprosy patients treated in Cáceres-MT, Brazil in the period 2000 to 2017. METHODS: A retrospective cohort study and survival analysis were performed in the hyperendemic municipality of Cáceres in the state of Mato Grosso. The study population consisted of newly diagnosed leprosy patients released from treatment between January 1, 2000 and December 31, 2017. The main outcome was the progression of the PD grade with regard to probability and time; and the evaluated covariates included clinical, operational and demographic variables. The Cox proportional risk model was used to estimate the risk ratio (Hazard Ratios) of the covariates. Both an univariate and a multivariate analysis were implemented, with 95% confidence intervals. RESULTS: The mean time for progression of the PD grade was 162 months for PB and 151 months for MB leprosy patients. The survival curve showed that 15 years after the release from treatment, the probability of PD grade progression was 35%, with no difference between PB and MB or age groups. Leprosy reactions and registered medical complaints of any kind during treatment were identified as risk factors with Hazard Ratios of 1.6 and 1.8 respectively. CONCLUSIONS: People released from treatment as cured of leprosy are susceptible to worsening of the PD, especially those who have had complications during multi-drug therapy treatment. This indicates that leprosy patients should be periodically monitored, even after the successful completion of multidrug therapy.

Low performance of operational indicators for leprosy control in the state of Bahia: spatiotemporal patterns, 2001-2014. / Baixo desempenho de indicadores operacionais de controle da hanseníase no estado da Bahia: padrões espaçotemporais, 2001-2014.

OBJECTIVE: To characterize spatiotemporal patterns of operational indicators for leprosy control in the state of Bahia from 2001 to 2014. METHODS: This is a population-based ecological study, with spatial distribution and autocorrelation of operational indicators for leprosy control. RESULTS: From 2001 to 2007, 42.7% (n=178) of the municipalities presented a cure rate lower than 75%, increasing to 61.4% (n =291) from 2009 to 2014. Between 2001 and 2007, 32.5% (n=54) of the municipalities reported more than 10% of the total number of relapses in the state, increasing to 36.9% (n=75) between 2008 and 2014. From 2001 to 2014, 38% (n=159) of the municipalities presented an assessment index of disability grading at the time of diagnosis within the regular performance parameter. Between 2009 and 2014, the number of municipalities with a high incidence of grade 2 disability (G2D) at the time of diagnosis increased, reaching 55.3% (n=230) of the municipalities. Most municipalities in the state of Bahia showed poor performance in the implementation of planned actions for leprosy control, with little change or relative worsening in the patterns of operational indicators throughout the historical series. CONCLUSION: The operational context in Bahia indicates significant institutional vulnerability, leading to the need for expansion and qualification of the surveillance and health care network in the different regions and conditions analyzed in the public health system (Sistema Único de Saúde - SUS).

De 2001 a 2014, em 38% (n = 159) dos municípios, o indicador de avaliação do grau de incapacidade física (GIF) no momento do diagnóstico se encontrava conforme o parâmetro regular de desempenho. Já no período de 2009 a 2014, houve aumento de municípios com alta ocorrência de GIF2 no momento do diagnóstico, atingindo 55,3% (n = 230) dos municípios. A maioria dos municípios do estado da Bahia apresentou desempenho insatisfatório na execução das ações de controle previstas para a hanseníase, com pouca mudança ou relativa piora nos padrões de indicadores operacionais ao longo da série histórica. CONCLUSÃO: O contexto operacional do estado da Bahia sinaliza graves dimensões de vulnerabilidade institucional, o que implica necessariamente a ampliação e a qualificação da rede de vigilância e atenção à saúde nas diferentes regiões e contextos analisados do Sistema Único de Saúde (SUS).

Disabilities in leprosy: an open, retrospective analyses of institutional records

Abstract Background and objectives: Leprosy remains a leading cause of peripheral neuropathy and disability in the world. Primary objective of the study was to determine the incidence of deformities present at a time of diagnosis and new deformities that patients develop over follow up period. Material and methods: An open, retrospective cohort study was performed at a tertiary medical center in western India. Recruitment phase of the study was of 2 years (2009-2010) followed by observation/follow up phase of 7 years till 31st December 2017. New patients with leprosy and released from treatment cases who presented with deformity as defined by WHO disability grade (1998) and subsequently developing new deformities during the follow up period of up to 7 years were included in the study. Results: The study included 200 leprosy patients. Of the total 254 deformities, 168 (66.14%) deformities were noticed at the moment of diagnosis, 20 (7.87%) deformities occurred during the follow up phase. Of all patients, 21.25% had Grade 1 deformity and 6.31% had Grade 2 or more severe deformity. Deformities of hand were most common in 44.48%, followed by feet 39.76%, and face 15.74% respectively. Limitation of study: Mode of inclusion of patient was self-reporting during follow up phase so there is possible under reporting of the disabilities. Conclusion: New deformities continue to develop in certain forms of leprosy even after release from treatment. Long-term & regular follow up of patients who have been released from treatment is required.

Evaluation of nerve growth factor serum level for early detection of leprosy disability.

INTRODUCTION: this research aimed to analyze nerve growth factor (NGF) contents as diagnostic tools for early disability in leprosy patients and the cut-off point value. METHODS: research samples consisted of 79 leprosy patients with disability grade 0 or 1 who met the clinically approved inclusion criteria. The age of patients ranged from 14 to 50 years. For both sample groups, blood serum was collected to determine NGF concentration. NGF level was analyzed by enzyme-linked immunosorbent assay (ELISA) according to the manual guide of the kit insert from Cussabio®. Statistical analysis used SPSS 17 software for Windows. A comparison was performed with the Student's t-test and the NGF concentration cut-off point was determined using a receiver operating characteristic (ROC) curve. RESULTS: the research result demonstrated that NGF concentration in multibacillary leprosy with disability grade 0 was higher than in grade 1. Leprosy with disability grade 0 had an NGF content reaching 100.46 pg/mL, while those with grade 1 had a lower concentration of NGF at 30.56 pg/mL. The higher disability grade indicated a lower NGF concentration in the blood serum. Based on the ROC analysis result, the NGF cut-off was shown to be 81.43 pg/mL. This result indicated that low NGF in nerve and skin lesions of leprosy patients contributes to early peripheral nerve malfunction due to Mycobacterium leprae infection. CONCLUSION: these results prove that NGF can be used as a marker of early disability in leprosy, with the cut-off value at 81.43 pg/mL.

Risk factors for physical disability upon release from multidrug therapy in new cases of leprosy at a referral center in Brazil.

The present study sought to investigate the risk factors for physical disability upon release from multidrug therapy (MDT) in new cases of leprosy, registered at a referral center in Brazil. This is a longitudinal and retrospective study that evaluated 260 patients. Multivariate analyses, using both the ordinal logistic regression, as well as the classification and regression tree (CART) algorithm were performed to determine the factors associated with physical disability upon release from treatment. The prevalence of disability did not differ significantly between diagnosis and release from treatment. Number of affected nerves and sensory impairment upon diagnosis were risk factors for disability at the end of MDT. The analysis using the CART algorithm resulted in the development of a clinical score to predict the risk of disability upon release from MDT. The decision tree may have a direct applicability in clinical practice for professionals dealing with leprosy, as it allows them to identify patients with a higher risk of physical disability through the use of simple and widely available clinical tests. This study also shows that the disability grade upon admission is the main risk factor for disability upon release from MDT. This result draws attention to the importance of early diagnosis in disability prevention.

Chronic aspects of leprosy-neglected but important.

The chronic aspects of leprosy are discussed here. They are a consequence of the peripheral nerve damage that affects many patients during their lifetime with leprosy. The peripheral nerve damage leaves people unable to feel and with weakness in their hands and feet. They are at risk of damaging their hands and feet, causing the disabilities and deformities that characterise late leprosy. More than 200 000 new leprosy patients are diagnosed globally each year. Better data are needed from cohort studies to estimate the number of patients developing nerve damage and modelling studies are needed to estimate the number of patients who develop disabilities. For some of them, this will be a lifelong disability. Nerve damage is caused by inflammation in leprosy-affected nerves. Patients with nerve damage of <6-mo duration need treatment with steroids. About 66% of multibacillary patients will develop nerve damage. Plastic graded monofilaments can be used to detect nerve damage in leprosy and diabetic clinics. Assessing nerve damage and treating patients with steroids in leprosy programmes needs to be strengthened. The World Health Organization has a successful programme for supplying antibiotics for treating leprosy infection to national leprosy programmes.
