Levantamento de dados para estudo dos fatores associados à falha terapêutica em hanseníase / Data collection to study the factors associated with failure leprosy therapy

A Hanseníase é uma doença infectocontagiosa de caráter crônico, evolução lenta, causada pelo Mycobacterium leprae (M. leprae). A transmissão ocorre por meio do trato respiratório, e para o desenvolvimento da doença existe a necessidade da susceptibilidade, além do contato íntimo e prolongado. Para fins terapêuticos a Organização Mundial da Saúde (OMS) traz uma classificação mais simples que é baseada no número de lesões cutâneas. Os casos com até cinco lesões são considerados paucibacilares e aqueles com mais de cinco lesões são multibacilares. Apesar da implantação da poliquimioterapia (PQT) pela OMS ter sido um importante avanço técnico na história do controle da doença, em 2019 ainda foram notificados 202.185 novos casos no mundo, sendo o Brasil o segundo em concentração de casos. Um indicador importante para o controle da hanseníase são as taxas de retratamento, definido como nova notificação de hanseníase em paciente que já tenha recebido tratamento anterior, suas causas incluem abandono, insuficiência terapêutica, falência terapêutica, alteração de esquema por erro diagnóstico e recidiva. Embora um grande número de casos de recidivas seja detectado no Brasil, apenas 8,4%, 13,3% e 1,9% dos casos podem ser explicados por mutações que sabidamente conferem resistência bacilar aos medicamentos utilizados na PQT: rifampicina (RFP), dapsona (DDS) e ofloxacina (OFLO), respectivamente. Além dos aspectos relacionados ao patógeno, a contribuição do hospedeiro para esse cenário, apesar de pouco estudada, deve ser de grande importância. No geral a resposta ao medicamento é variável entre indivíduos, ocasionando falta de eficácia farmacológica ou reação adversas, em partes esses eventos podem ser explicados pela farmacogenética. Conhecer fatores genéticos que interferem no metabolismo dos medicamentos pode contribuir para melhores resultados terapêuticos. Dentre os desafios para atingir a eliminação da hanseníase estão a ausência de novas ferramentas de diagnóstico e de entendimento das causas associadas a recidiva e à não adesão a PQT, uma vez que a resistência medicamentosa explica pouco da reativação da doença, deste modo, o presente estudo teve como finalidade constituir banco de dados em hanseníase para estudos de associação do tipo caso-controle sobre os fatores associados com a falha terapêutica da PQT convencional. Dos 240 prontuários avaliados, 119 foram classificados como casos de falência terapêutica ou recidiva e 121 como sucesso terapêutico, aqui denominados como controles, a maioria dos pacientes era do sexo masculino, branco e procedente do estado de São Paulo; Em relação à faixa etária de diagnóstico, 18% foram diagnosticados com idade entre 40 e 49 anos, enquanto nos controles 14% tiveram diagnóstico com idade inferior a 19 anos; quanto à forma clínica da doença, 59% dos casos e 47% dos controles foram classificados como virchoviano. Dentre os casos de falência terapêutica ou recidiva, a resistência molecular explicou apenas 5,8 % dos casos de retratamento. Esse dado reforça a urgência de estudos que esclareçam as causas da falha terapêutica em hanseníase, contribuindo assim para o estabelecimento de medidas que visem o alcance de melhores índices relacionados aos desfechos terapêuticos.(AU)

Leprosy is a chronic infectious disease with insidious evolution, caused by Mycobacterium leprae (M. leprae). Transmission occurs through the respiratory tract, and the onset of the disease depends on susceptibility, in addition to intimate and prolonged contact with untreated patients. For therapeutic purposes, the World Health Organization's (WHO) classification is based on the number of skin lesions. Cases with up to five lesions are considered paucibacillary and those with more than five lesion are multibacillary. Although the implementation of multidrugtherapy (MDT) by WHO was an important technical advance in the history of disease control. In 2019, 202,185 new cases were reported in the world, with Brazil the second in the highest number of cases. An important indicator for the control of leprosy is retreatment rate, defined as a new notification of leprosy in a patient who has already received previous treatment. Its causes include abandonment, therapeutic failure, , alteration of the regimen due to diagnostic error and relapse. Although a large number of cases of relapses are detected in Brazil, only 8.4%, 13.3% and 1.9% of cases can be explained by mutations that are known to confer bacillary resistance to drugs used in the MDT: rifampicin (RFP), dapsone (DDS) and ofloxacin (OFLO), respectively. In addition to aspects related to the pathogen, the host's contribution to this scenario, although little studied, is highly important. In general, the response to the drug treatment is variable between individuals, causing a lack of pharmacological efficacy or adverse reactions. , These events may be explained by pharmacogenetics. Knowing genetic factors that interfere with drug metabolism can contribute to better therapeutic results. Among the challenges to achieve leprosy elimination are the absence of new diagnostic tools and understanding of the causes associated with relapse and non-adherence to MDT, since drug resistance explains little about the reactivation of the disease. Thus, the present study aimed at constituting a leprosy database for case-control association studies on factors associated with conventional MDT therapeutic failure. Of the 240 medical records evaluated, 119 were classified as cases of therapeutic failure or relapse and 121 as therapeutic success, here referred to as controls. The majority of patients were male, white and from the state of São Paulo. Regarding the age of diagnosis, 18% were diagnosed between 40 and 49 years, while in controls, 14% were diagnosed under 19 years; as to the clinical form of the disease, 59% of the cases and 47% of the controls were classified as lepromatous. Among the cases of therapeutic failure or relapse, molecular resistance explained only 5.8% of retreatment cases. This data reinforces the urgency of studies that clarify the causes of therapeutic failure in leprosy, thus contributing to the establishment of measures aimed at achieving better therapeutic outcomes(AU).

Introdução: A úlcera plantar por hanseníase é uma lesão no pé resultante da falta de sensibilidade plantar. O objetivo é descrever o tratamento realizado em portadores de úlceras plantares por hanseníase. Métodos: Estudo de prontuários de portadores de úlcera plantar atendidos no Hospital Sarah em Brasília, de 2006 a 2016, quanto ao sexo, idade, etiologia, localização e tratamento. Resultados: Foram atendidos 27 pacientes, 17(62,96%) homens e 10 (37,04%) mulheres, procedentes de Goiás e DF, na faixa etária de 41 a 60 anos (40,74%). Todos necessitaram de um ou mais procedimentos cirúrgicos. Conclusão: Observou-se maior frequência no sexo masculino, grau avançado, localizadas no primeiro artelho. Todos necessitaram de procedimentos cirúrgicos e não cirúrgicos, evoluindo com cicatrização completa da ferida, amputação transtibial em um caso e de artelhos em sete casos, e 90% dos casos apresentaram recorrência da úlcera após um ano.

Introduction: Leprosy-induced plantar ulcers result from a lack of plantar sensitivity. Objective: This study aimed to describe the treatment provided to patients with leprosy-induced plantar ulcers. Methods: We retrospectively reviewed the medical records of patients with plantar ulcers treated at Sarah Hospital in Brasilia from 2006 to 2016 and collected information about sex, age, etiology, location, and treatment. Results: A total of 27 patients (17 [62.96%] men, 10 [37.04%] women; 40.74% were aged 41­60 years) were treated from Goiás and the Federal District. All required ≥1 surgical procedure. Conclusion: A higher frequency of advanced grade was observed in men, primarily on the first toe. All needed surgical and non-surgical procedures and achieved complete wound healing. Transtibial amputation was required in 1 case and toe amputation in 7 cases; 90% patients developed ulcer recurrence after 1 year.

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

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.

O objetivo desse estudo foi descrever as características sociodemográficas e epidemiológicas da população atendida na sala de curativo de um ambulatório dermatológico. Trata-se de um estudo de corte seccional, descritivo baseado no levantamento de casos de pessoas atendidas para o tratamento de úlceras crônicas decorrentes de dermatopatias. A fonte de dados para a pesquisa foram os prontuários disponibilizados pelo Serviço de Arquivo Médico e Estatística (SAME) do Instituto Lauro de Souza Lima (ILSL), correspondendo ao período de janeiro a dezembro do ano de 2011. Foram avaliados 486 prontuários, dos quais, na população estudada, apontaram as características sociodemográficas predominantes: o gênero masculino (57%), idade 70 e mais anos (36,42%), casados (49,4%), aposentados (34,6%), raça branca (87,9%), escolaridade com ensino fundamental incompleto (19,8%), procedentes do Estado de São Paulo (98,15%). A comorbidade prevalente foi a Hipertensão Arterial Sistêmica (n=224; 46,1), acompanhada de Diabetes mellitus II com 117 (24,1%). A maioria das úlceras (n=218; 44,9%) encontradas foi neuropática, a média de tempo de existência em anos foi de 5,4 anos, com desvio padrão de 7,2. Tais achados servem de alerta aos gestores e profissionais, para que conheçam a situação das pessoas atendidas na sala de curativo, no que tange as suas características sociodemográficas, clínicas e epidemiológicas para implementação de protocolos, ações políticas e assistenciais.

The aim of this study was to describe the sociodemographic and epidemiological characteristics of the population served in the dressing room of a dermatological clinic. This is a descriptive cross-sectional cohort study based on the survey of cases of people met for the treatment of chronic ulcers resulting from skin diseases. A source of data for the study were the records made available by the Medical Records and Statistics (SAME) of the Instituto Lauro de Souza Lima (ILSL), corresponding to the period from January to December of 2011 records 486 of which were evaluated in the study population sociodemographic characteristics predominated: males (57%), age 70 years old and over (36.42%), married (49.4%), retired (34.6%), white (87.9%), incomplete primary school education (19.8%), from the State of São Paulo (98.15%). A prevalent comorbidity was Hypertension (n=224; 46.1), followed by diabetes mellitus II with 117 (24.1%). Most ulcers (n=218; 44.9%) was found neuropathic, the average time of existence in years was 5.4 years, with a standard deviation of 7.2. These findings serve as a warning to managers and professionals, so that they know the situation of people met in the dressing room, regarding their sociodemographic, clinic and epidemiological characteristics for implementing protocols, policies and assistance actions.

Leprosy in a University Hospital in Southern Brazil.

BACKGROUND: Leprosy is an infectious disease that may lead to irreversible nerve damage, compromising patient's quality of life and leading to loss of working years. OBJECTIVES: To evaluate the epidemiological profile of patients followed at a University Hospital. MATERIALS AND METHODS: This is a retrospective observational study, based on a review of medical records. We studied the clinical and epidemiological features of patients with leprosy monitored at the Hospital de Clínicas of the Federal University of Paraná between January 2005 and January 2010. RESULTS: The mean age was 47.51, while 35.94% of patients were aged 41-60. The male:female rate was 1.8:1. The most prevalent occupations were: retired, students or rural workers. Patients came mainly from Curitiba or nearby areas, but there were also patients from the countryside. The mean diagnostic delay was 24.57 months. Multibacillary forms prevailed, with the lepromatous variety being the most common, closely followed by the borderline type. Neural enlargement was found in more than 50% of the patients and 48.44% of them developed reactional states. Hemolysis was the most commonly detected drug side effect. Initial functional evaluation was possible in 70% of patients, 55% of whom had disabilities upon diagnosis. The most prevalent associated disease was hypertension. CONCLUSIONS: This study showed an important diagnostic delay and a high rate of sequelae in this specific population. Brazil is one of the few remaining countries that has not yet eradicated leprosy and it is important to improve health policies in order to prevent sequelae and achieve eradication.
