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.

Botulinum toxin type A in chronic neuropathic pain in refractory leprosy / Toxina Botulínica Tipo A em Dor Neuropática Crônica em Hanseníase

ABSTRACT Neuropathic pain is a chronic syndrome that is difficult to treat and often affects patients with leprosy. Recommended treatment includes the the use of analgesic drugs, codeine, tricyclic antidepressants, neuroleptics, anticonvulsants and thalidomide, but without consensus on uniform dose and fully satisfactory results. Objective: To analyze botulinum toxin type A (BoNT-A) effectiveness in treatment of chronic neuropathic pain in refractory leprous patients, as well as evaluate and compare the quality of life of patients before and after using the medication. Methods: We used a specific protocol including clinical, demographic, DN4 protocol, analogue scale (VAS), sensory evaluation and evaluation of the WHOQOL-BREF. Therapeutic intervention was performed with BOTOX® BTX-A 100U administered subcutaneously. Fifteen patients were evaluated on days 0, 10 and 60. Results: Patients on VAS showed pain between 5 and 10, in one case there was complete pain relief in 60 days, while others showed improvement in the first week with the return of symptoms with less intensity after this period. WHOQOL-BREF's domains Quality of Life and Physical to have a significant increase in QOL. Conclusion: BoNT-A proved to be a good therapeutic option in relieving pain with improved quality of life for these patients.

RESUMO A dor neuropática é uma síndrome crônica que é difícil de tratar e freqüentemente afeta pacientes com hanseníase. O tratamento recomendado inclui o uso de drogas analgésicas, codeína, antidepressivos tricíclicos, neurolépticos, anticonvulsivantes e talidomida, mas sem consenso sobre dose uniforme e resultados plenamente satisfatórios. Objetivo: Busca-se analisar a efetividade da toxina botulínica tipo A no tratamento da dor neuropática crônica hansênica refratária. Método: Estudo de intervenção do tipo ensaio clínico em portadores de dor neuropática crônica hansênica. Foram coletados dados epidemiológicos, protocolo DN4, escala analógica da dor (EVA), avaliação sensitiva, motora a avaliação do WHOQOL-Bref. Realizado intervenção terapêutica com toxina botulínica tipo A 100U. Os pacientes foram avaliados nos dias de 0, 10 e 60. A dor neuropática foi mais frequente no sexo masculino, na faixa etária de 40 à 49 anos. Resultados: Da forma Dimorfa, multibacilar com baciloscopia positiva e incapacidades presentes. Os escores EVA variam entre 5 e 10, todos os pacientes apresentaram alterações sensoriais. O WHOQOL-Bref apresentou melhora após o tratamento com TxBA. A TxBA foi bem tolerada o único efeito adverso notável foi dor leve. E com apenas uma única aplicação de TxBA promoveu efeitos analgésicos a longo prazo em pacientes com dor associada à alodinia, sugerindo que a analgesia observada pode ser causada por um efeito periférico da TxBA em terminações nociceptivas. Conclusão: O estudo sugere que a TxBA é uma boa opção para os casos de dor neuropática crônica hansênica, no entanto, novos estudos são necessários para confirmar estes resultados.

Assessment of the sensory and physical limitations imposed by leprosy in a Brazilian Amazon Population

Abstract INTRODUCTION Leprosy often results in sensory and physical limitations. This study aimed to evaluate these limitations using a quantitative approach in leprosy patients in Belém (Pará, Brazil). METHODS This epidemiological, cross-sectional study measured the sensory impairment of smell and taste through the use of a questionnaire and evaluated activity limitations of daily life imposed by leprosy through the Screening of Activity Limitation and Safety Awareness (SALSA) Scale. Data were collected from 84 patients and associations between the degree of disability and clinical and epidemiological characteristics were assessed. RESULTS The majority of patients were men (64.3%), married (52.4%), age 31-40 years old (26.2%), had primary education (50%), and were independent laborers (36.9%). The multibacillary operational classification (81%), borderline clinical form (57.1%), and 0 degrees of physical disability (41.7%) were predominant. SALSA scores ranged from 17 to 59 points, and being without limitations was predominant (53.6%). The risk awareness score ranged from 0 to 8, with a score of 0 (no awareness of risk) being the most common (56%). Evaluation of smell and taste sensory sensitivities revealed that 70.2% did not experience these sensory changes. Patients with leprosy reactions were 7 times more likely to develop activity limitations, and those who had physical disabilities were approximately four times more likely to develop a clinical picture of activity limitations. CONCLUSIONS Most patients showed no sensory changes, but patients with leprosy reactions were significantly more likely to develop activity limitations. Finally, further studies should be performed, assessing a higher number of patients to confirm the present results.

Thermographic analysis and autonomic response in the hands of patients with leprosy

Abstract: Background: Low temperatures and slow blood flow may result from peripheral neuropathy caused by leprosy, and the simple detection of cold fingers could already be a preliminary classification for these patients. Objective: To investigate whether infrared thermography would be able to measure this change in temperature in the hands of people with leprosy. Method: The study assessed 17 leprosy patients who were under treatment at the National Reference Center for Sanitary Dermatology and Leprosy, Uberlândia/MG, and 15 people without leprosy for the control group. The infrared camera FLIR A325 and Therma CAM Researcher Professional 2.9 software were used to measure the temperature. The room was air-conditioned, maintaining the temperature at 25°C; the distance between the camera and the limb was 70 cm. The vasomotor reflex of patients was tested by a cold stress on the palm. Results: The study showed a significant interaction between the clinical form of leprosy and temperature, where the control group and the borderline-borderline form revealed a higher initial temperature, while borderline-lepromatous and lepromatous leprosy showed a lower temperature. Regarding vasomotor reflex, lepromatous leprosy patients were unable to recover the initial temperature after cold stress, while those with the borderline-tuberculoid form not only recovered but exceeded the initial temperature. Conclusion: Thermography proved a potential tool to assist in the early detection of neuropathies, helping in the prevention of major nerve damage and the installation of deformities and disabilities that are characteristic of leprosy.

Clinical and epidemiological profile of leprosy patients attended at Ceará, 2007-2011

Abstract: Background: Leprosy is an infectious chronic condition associated with potentially serious physical, social and psychological impacts. Objectives: To characterize the clinical and epidemiological profile of leprosy patients treated from 2007 to 2011 in the University Hospital of Ceará, Northeastern Brazil. Methods: This is a retrospective and descriptive study. The study population consisted of residents in the state of Ceará treated in a dermatology clinic between 2007-2011. Clinical and epidemiological data analyzed were obtained from medical records and from the database of national Information System for Notifiable Diseases. Results: 475 cases were analyzed, mostly women (51.8%), aged 45-59 years (35.0%) - mean of 45.2 years at diagnosis - with 6.3% of children under 15 , with low education (73.7%), white color (68.8%), residency in the city of Fortaleza (82.3%), and no defined work occupation (59.6%). At diagnosis, most patients were multibacillary (MB) (65.5%), had borderline clinical form (48.0%), and 22.7% had physical disability (8.0% with grade 2), predominantly in MB cases (p <0.001). We observe worsening of disability in 5.1% of cases post-MDT. The proportion of cases with reactional episodes was 42.7%, mainly during MDT (51.2%). Conclusion: This is the first study conducted in this hospital context, revealing late diagnosis, high burden of disease, hidden endemicity, and high social vulnerability in the state of Ceará. This study reinforces the need to strengthen health care network for timely diagnosis and treatment, aiming at longitudinality of assistance.

Limited activity and social participation after hospital discharge from leprosy treatment in a hyperendemic area in north Brazil / Pós-alta de hanseníase: limitação de atividade e participação social em área hiperendêmica do Norte do Brasil

INTRODUCTION: Neural damages are among the main factors that contribute to physical disability in leprosy. Systematic monitoring using a broad physical, psychological and social approach is necessary. OBJECTIVE: The objective of this study was to characterize the limitation of activity and social participation and its correlation with disabilities and/or impairment in individuals after being discharged from a multidrug leprosy therapy. METHOD: A cross-sectional study conducted in Araguaína, state of Tocantins, which is a leprosy hyperendemic municipality. We included cases of patients who were discharged from treatment considered as cured from January 2004 to December 2009. We performed dermatological examination and applied the Screening Activity Limitation and Safety Awareness (SALSA) and social participation scales. RESULTS: We included 282 individuals (mean age: 45.8 years old). The paucibacillary operational classification was more common (170; 60.3%). The eye-hand-foot score ranged from 0 to 12 (mean: 0.7). A total of 84 (29.8%) individuals presented limited activity. A slight restriction in social participation occurred in 18 (6.3%) cases. There was a statistically significant correlation between activity limitation, age (r = 0.40; p < 0.0001) and degree of functional limitation (r = 0.54; p < 0.0001), as well as of restricted social participation, activity limitation (r = 0.56, p < 0.0001) and functional limitations (r = 0.54, p < 0.0001). CONCLUSION: Functional limitation due to leprosy had an impact on the conduct of activities and social participation after the discharge from a leprosy treatment. The association between Screening of Activity Limitation and Safety Awareness and participation scales will assist in designing evidence-based assistance measures. .

Manifestações músculoesqueléticas e auto-anticorpos em crianças e adolescentes com hanseníase / Musculoskeletal manifestations and autoantibodies in children and adolescents with leprosy

Introdução: A hanseníase é uma doença infecciosa crônica causada pelo Mycobacterium leprae. É considerada um dos maiores problemas de saúde pública nos países em desenvolvimento. Os principais sinais clínicos são manchas de pele com perda de sensibilidade e envolvimento de nervos periféricos. Manifestações musculoesqueléticas são descritas em adultos, mas este envolvimento é raramente descrito na população pediátrica. Objetivo: Avaliar envolvimento musculoesquelético e auto-anticorpos em pacientes pediátricos com hanseníase. Métodos: Foram avaliados 50 pacientes com hanseníase e 47 crianças e adolescentes saudáveis de acordo com manifestações musculoesqueléticas (artralgia, artrite e mialgia), síndromes dolorosas musculoesqueléticas (fibromialgia juvenil, síndrome de hipermobilidade articular benigna, síndrome miofascial e tendinite) e painel de auto-anticorpos e crioglobulinas. Escores de avaliação de saúde e tratamento foram realizados nos pacientes com hanseníase. Resultados: A frequência de manifestações musculoesqueléticas foi maior em pacientes com hanseníase comparada aos controles (14% vs. 0%, p=0,0012). Cinco pacientes com hanseníase tinham poliartrite assimétrica das pequenas articulações das mãos (10% vs. 0%, p=0,057). Comprometimentos da função do nervo, reação tipo I hansênica, e neuropatia silenciosa foram observados nos pacientes com hanseníase (p=0,0006; p=0,003; p=0,0059; respectivamente). Nenhum dos pacientes e controles apresentou síndromes de dor musculoesquelética e as frequências dos anticorpos e crioglobulinas foram semelhantes nos dois grupos (p > 0,05). Comprometimentos da função nervosa, reação hansênica tipo I e neuropatia silenciosa foram observados em pacientes com versus sem manifestações musculoesqueléticas (p=0,0036; p=0,0001; p=0,309; respectivamente), bem como subtipos de hanseníase multibacilar (86% vs. 42%, p=0,045). A escala visual analógica do médico (VAS), dos pacientes (VAS), de dor (VAS) e CHAQ foram maiores em...

Introduction: Leprosy is a chronic infectious disease caused by Mycobacterium leprae. It is considered one of major public health issue in developing countries. The important clinical signs of leprosy are hypopigmented or reddish localized skin lesions with loss of sensation and peripheral nerves involvement. Musculoskeletal manifestations were described in leprosy adult patients and these involvements were rarely described in pediatric leprosy population. Objective: To evaluate musculoskeletal involvement and autoantibodies in pediatric leprosy patients. Methods: 50 leprosy patients and 47 healthy children and adolescents were assessed according to musculoskeletal manifestations (arthralgia, arthritis and myalgia), musculoskeletal pain syndromes (juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome and tendinitis) and a panel of autoantibodies and cryoglobulins. Health assessment scores and treatment were performed in leprosy patients. Results: The frequency of at least one musculoskeletal manifestation was significantly higher in leprosy patients compared to controls (14% vs. 0%, p=0.0012) and five leprosy patients had asymmetric polyarthritis of small hands joints (10% vs. 0%, p=0.057), Nerve function impairment, type I leprosy reaction and silent neuropathy were significantly observed in leprosy patients (p=0.0006; p=0.003; p=0.0059; respectively). None of the patients and controls presented musculoskeletal pain syndromes and the frequencies of all antibodies and cyoglobulins were similar in both groups (p>0.05). Further analysis of leprosy patients showed that the frequencies of nerve function impairment, type I leprosy reaction and silent neuropathy were significantly observed in patients with versus without musculoskeletal manifestations (p=0.0036; p=0.0001; p=0.309; respectively), as well as multibacillary subtypes in leprosy (86% vs. 42%, p=0.045). The median of physician visual analogue scale (VAS)...

Antioxidant factors, nitric oxide levels, and cellular damage in leprosy patients

Introduction The immune response caused by Mycobacterium leprae is a risk factor for the development of oxidative stress (OS) in leprosy patients. This study aimed to assess OS in leprosy patients before the use of a multidrug therapy. Methods We evaluated the nitric oxide (NO) concentration; antioxidant capacity; levels of malondialdehyde, methemoglobin and reduced glutathione; and the activity of catalase and superoxide dismutase (SOD) in leprosy patients. Results We observed lower SOD activity in these leprosy patients; however, the NO levels and antioxidant capacity were increased. Conclusions The infectious process in response to M. leprae could primarily be responsible for the OS observed in these patients. .

Leprosy neuropathy: clinical presentations / Neuropatia da lepra: apresentacoes clinicas

Leprosy is a chronic infectious peripheral neuropathy caused by Mycobacterium leprae. The different clinical presentations of the disease are determined by the quality of the host immune response. Early detection of leprosy and treatment by multidrug therapy are the most important steps in preventing deformity and disability. Thus the early recognition of the clinical leprosy presentation is essential. Mononeuritis, mononeuritis multiplex (MM), polyneuritis (MM summation) are the most frequent. The frequent anesthetic skin lesions are absent in the pure neuritic leprosy presentation form. Isolated peripheral nerve involvement is common, including the cranial ones. Arthritic presentation is occasionally seen, usually misdiagnosed as rheumatoid arthritis. Attention should be given to autonomic dysfunctions in leprosy. There are clinical presentations with severe neuropathic pain - painful small-fiber neuropathy. Leprous late-onset neuropathy (LLON) clinical presentation should be considered facing a patient who develop an inflammatory neuropathy many years after a previous skin leprosy treatment.

A hanseníase é uma neuropatia periférica infecciosa, crônica, causada pelo Mycobacterium leprae. As diferentes apresentações clínicas são determinadas pela qualidade da resposta imune do hospedeiro. O diagnóstico precoce e a multi-droga terapia são os passos mais importantes na prevenção de deformidades e incapacidades. Dessa forma, o reconhecimento precoce da apresentação clínica da hanseníase é essencial. Mononeurites, mononeurites múltipla (MM), polineurite (superposição de MM) são as mais frequentes. As frequentes lesões anestésicas de pele estão ausentes na forma neurítica pura. Comprometimento de nervo isolado é comum, inclusive os cranianos. Apresentação com artrite é ocasionalmente vista, erroneamente diagnosticada como artrite reumatóide. Atenção deve ser dada às disfunções autonômicas na hanseníase. Há apresentações clínicas com dor neuropática grave - neuropatia dolorosa de pequenas fibras. Neuropatia de início tardio (LLON) é apresentação clínica que deve ser considerada frente a paciente que desenvolve neuropatia inflamatória muitos anos depois de tratamento prévio da lepra cutânea.

New sonographic measures of peripheral nerves: a tool for the diagnosis of peripheral nerve involvement in leprosy

To evaluate ultrasonographic (US) cross-sectional areas (CSAs) of peripheral nerves, indexes of the differences between CSAs at the same point (∆CSAs) and between tunnel (T) and pre-tunnel (PT) ulnar CSAs (∆TPTs) in leprosy patients (LPs) and healthy volunteers (HVs). Seventy-seven LPs and 49 HVs underwent bilateral US at PT and T ulnar points, as well as along the median (M) and common fibular (CF) nerves, to calculate the CSAs, ∆CSAs and ∆TPTs. The CSA values in HVs were lower than those in LPs (p < 0.0001) at the PT (5.67/9.78 mm2) and T (6.50/10.94 mm2) points, as well as at the M (5.85/8.48 mm2) and CF (8.17/14.14 mm2) nerves. The optimum CSA- receiver operating characteristic (ROC) points and sensitivities/specificities were, respectively, 6.85 mm2 and 68-85% for the PT point, 7.35 mm2 and 71-78% for the T point, 6.75 mm2 and 62-75% for the M nerve and 9.55 mm2 and 81-72% for the CF nerve. The ∆CSAs of the LPs were greater than those of the HVs at the PT point (4.02/0.85; p = 0.007), T point (3.71/0.98; p = 0.0005) and CF nerve (2.93/1.14; p = 0.015), with no difference found for the M nerve (1.41/0.95; p = 0.17). The optimum ∆CSA-ROC points, sensitivities, specificities and p-values were, respectively, 1.35, 49%, 80% and 0.003 at the PT point, 1.55, 55-85% and 0.0006 at the T point, 0.70, 58-50% and 0.73 for the M nerve and 1.25, 54-67% and 0.022 for the CF nerve. The ∆TPT in the LPs was greater than that in the HVs (4.43/1.44; p <0.0001). The optimum ∆TPT-ROC point was 2.65 (90% sensitivity/41% specificity, p < 0.0001). The ROC analysis of CSAs showed the highest specificity and sensitivity at the PT point and CF nerve, respectively. The PT and T ∆CSAs had high specificities (> 80%) and ∆TPT had the highest specificity (> 90%). New sonographic peripheral nerve measurements (∆CSAs and ∆TPT) provide an important methodological improvement in the detection of leprosy neuropathy.

Reacciones por lepra en un centro de referencia nacional en Colombia / Leprosy reactions in a Colombian national reference centre

Introducción. Colombia es el país de América con mayor proporción de casos nuevos de lepra con discapacidad grave. Para disminuir tal discapacidad se requiere el control de las reacciones, principal causa del daño neural en esta enfermedad. Objetivo. Describir las características clínicas y epidemiológicas y el tratamiento de los pacientes con reacciones de tipo 1 y 2 que consultaron al Centro Dermatológico Federico Lleras Acosta. Materiales y métodos. Se trata de un estudio descriptivo que incluyó la población de pacientes con diagnóstico clínico de reacciones de tipo 1 y de tipo 2 por lepra, que acudieron al centro entre los años 2003 y 2009. Resultados. Se estudiaron 96 reacciones, 35 del tipo 1 y 61 del tipo 2. El 75 % de los pacientes provenía de los departamentos de Tolima, Cundinamarca, Santander y Boyacá. El 56 % de las reacciones de tipo 1 se presentaron antes de iniciar la poliquimioterapia para la lepra; el dermatólogo tratante consideró que las reacciones que se presentaron después de suspender la poliquimioterapia eran recaídas. El 94 % de las reacciones de tipo 1 se trataron con corticoides orales. El 97 % de los pacientes con reacciones de tipo 2 presentaron eritema nudoso, y todos se trataron con talidomida. Conclusiones.La clínica de la reacción de tipo 1 puede orientar al diagnóstico de la lepra en un paciente sin el antecedente de esta enfermedad (56 %). La reacción de tipo 1 que se inicia después de suspender la poliquimioterapia para la lepra, podría ser una manifestación de recaída de la enfermedad. La reacción de tipo 2 es más frecuente en hombres, con una relación hombre a mujer de 4:1. El 97 % de los pacientes con reacción de tipo 2 presentó eritema nudoso.

Introduction: Colombia is the country in America with the highest proportion of new cases leprosy with severe disability. To decrease such disability it is necessary to control these reactions, the main cause of nerve damage in leprosy. Objective: To describe the clinical and epidemiological characteristics and the treatment of patients with type 1 and 2 leprosy reactions who consulted the Centro Dermatológico Federico Lleras Acosta. Materials and methods: It is a descriptive study which included patients with clinical diagnoses of type 1 and 2 reactions who were seen in the center between 2003 and 2009. The town of origin of the patients, their age, clinical features and treatments were analysed. Results: We studied 96 reactions in 87 patients, 35 type 1 and 61 type 2 reactions; 75% of the patients came from the departments of Tolima, Cundinamarca, Santander and Boyacá; 77% of type 1 reaction occurred before the beginning of multidrug therapy for leprosy. The reactions that started after stopping the multidrug therapy were considered as a leprosy relapse. Conclusions: Correct identification of type 1 reaction by the general practitioner will allow the diagnosis of leprosy in a large percentage of patients. The type 1 reaction that begins after stopping the leprosy multidrug therapy may be a manifestation of a relapse of the disease.

Cutaneous lesions sensory impairment recovery and nerve regeneration in leprosy patients

It is important to understand the mechanisms that enable peripheral neurons to regenerate after nerve injury in order to identify methods of improving this regeneration. Therefore, we studied nerve regeneration and sensory impairment recovery in the cutaneous lesions of leprosy patients (LPs) before and after treatment with multidrug therapy (MDT). The skin lesion sensory test results were compared to the histopathological and immunohistochemical protein gene product (PGP) 9.5 and the p75 nerve growth factor receptors (NGFr) findings. The cutaneous neural occupation ratio (CNOR) was evaluated for both neural markers. Thermal and pain sensations were the most frequently affected functions at the first visit and the most frequently recovered functions after MDT. The presence of a high cutaneous nerve damage index did not prevent the recovery of any type of sensory function. The CNOR was calculated for each biopsy, according to the presence of PGP and NGFr-immunostained fibres and it was not significantly different before or after the MDT. We observed a variable influence of MDT in the recovery from sensory impairment in the cutaneous lesions of LPs. Nociception and cold thermosensation were the most recovered sensations. The recovery of sensation in the skin lesions appeared to be associated with subsiding inflammation rather than with the regenerative activity of nerve fibres.
