Negligência no diagnóstico precoce de hanseníase na atenção primária: um relato de caso / Negligence in the early diagnosis of leprosy in primary care: a case report

A hanseníase é uma doença infecciosa, transmissível, de caráter crônico, com potencial grau de incapacidade, que ainda persiste como problema de saúde pública no Brasil. A demora e a falta de conhecimento técnico para realizar o diagnóstico resulta em inúmeros prejuízos aos pacientes acometidos pela doença, sendo que, a prevenção das incapacidades está relacionada diretamente com o diagnóstico precoce da doença. Com a finalidade de evitar a negligência diagnóstica e o desenvolvimento de incapacidades físicas, ressaltamos a importância do conhecimento técnico sobre o diagnóstico e o manejo da hanseníase por profissionais da saúde em qualquer nível de atenção à saúde ou especialidade.

Hansen is an infectious disease, transmissible, of a chronic nature, with serious potential for disability, which still persists as a public health problem in Brazil. The delay and the lack of technical knowledge to carry out the diagnosis with numerous prejudices to the patients affected by the disease, since the prevention of disabilities is directly related to the early diagnosis of the disease. In order to avoid diagnostic negligence and the development of physical disabilities, we highlight the importance of technical knowledge about the diagnosis and management of training by health professionals at any level of health care or special care.

Eritema nodoso hansênico com apresentação vesiculosa simulando infecção herpética: um relato de caso / Erythema nodosum leprosum with vesicular presentation simulating herpetic infection: a case report

Contexto: As reações hansênicas são episódios inflamatórios agudos imunomediados que podem ocorrer em indivíduos com hanseníase. Lesões atípicas de eritema nodoso hansênico (ENH) são raras e podem se apresentar como pústulas, bolhas, necrose, úlceras e, eventualmente, podem simular outras doenças como a síndrome de Sweet e eritema multiforme. Descrição do caso: Paciente do sexo masculino, 24 anos de idade, com diagnóstico prévio de hanseníase virchowiana e realização de tratamento adequado, com término da poliquimioterapia quatro anos antes de comparecer ao nosso serviço quando foi avaliado, apresentando pequenas vesículas translúcidas agrupadas sobre uma base eritematosa e áreas com crostas necróticas, simulando lesões herpéticas, na porção superior das costas, parte inferior do pescoço e haste do pênis. O exame histopatológico da biópsia cutânea foi sugestivo de reação tipo 2 e o tratamento com talidomida foi satisfatório. Discussão: As reações na hanseníase representam episódios de hipersensibilidade aguda a antígenos de Mycobacterium leprae e podem se desenvolver antes, durante ou após o término do tratamento. Acredita-se que o ENH, ou reações do tipo 2, ocorram devido à deposição de imunocomplexos em múltiplos órgãos em pacientes que apresentam a forma multibacilar. Conclusões: As reações hansênicas são desafios no manejo da hanseníase, especialmente pelo fato de a maioria das sequelas permanentes ser secundária a esses episódios inflamatórios agudos. O conhecimento das possíveis apresentações atípicas das reações hansênicas é fundamental para o diagnóstico precoce e o tratamento adequado, a fim de prevenir morbidade grave relacionada à hanseníase.

Lepra en la isla colombiana de Providencia / Leprosy in the Colombian island of Providencia

San Andrés y Providencia son islas colombianas en el mar de las Antillas. San Andrés tiene 68.283 habitantes y allí se han registrado casos de lepra en inmigrantes provenientes del interior colombiano. Providencia tiene 5.037 habitantes e, históricamente, los programas de salud no tenían registros de la enfermedad; no obstante, en el 2009 se confirmaron dos casos de lepra multibacilar histioide y, posteriormente, otros dos, lo cual representa una prevalencia de 8 casos por 10.000 habitantes y la convierte en un sitio hiperendémico para lepra. Inicialmente, se diagnosticó lepra histioide en una niña de 14 años y, durante su estudio, se encontró la misma forma clínica de la enfermedad en su padre. Recientemente, se detectó lepra multibacilar en otro miembro de la misma familia y, lepra indeterminada, en una niña de otro núcleo familiar. El objetivo de este trabajo fue presentar estos casos clínicos ante la comunidad científica y los entes de salud pública, y llamar la atención de las autoridades de salud sobre la necesidad de establecer programas de vigilancia epidemiológica continua en la isla, incorporando las nuevas herramientas disponibles en el Programa de Control de la Lepra.

San Andrés and Providencia are Colombian islands in the Caribbean Sea. San Andrés has 68,283 inhabitants and has registered cases of leprosy in immigrants from continental Colombia. Providencia has 5,037 inhabitants and historically health programs did not have records of the disease, but in 2009 two cases of multibacillary histoid leprosy were confirmed and, subsequently, another two, which represents a prevalence of 8 cases per 10,000 inhabitants and places the island as a hyperendemic site for leprosy. Initially, a 14-year-old girl with histoid leprosy was diagnosed and, exploring this case, her father was diagnosed with the same clinical form of leprosy. Recently, a new intrafamilial patient with multibacillary leprosy and an extrafamilial case of a girl with undetermined leprosy were detected. The objective of this study was to present to the scientific community and the public health officers these clinical cases and to draw the attention of the sanitary authorities on the necessity of establishing continuous programs of leprosy epidemiological surveillance on the island using the new tools available in the Programa de Control de la Lepra (Leprosy Control Program).

Giant cells lepromatous leprosy. Diffuse dermatitis with exuberant foreign body giant cells in treated lepromatous leprosy / Células gigantes en lepra lepromatosa. Dermatitis difusa con células gigantes tipo cuerpo extraño exuberantes en lepra lepromatosa tratada

Patients with lepromatous leprosy that have received treatment for many years usually get follow up biopsies for persistent skin lesions or positive bacilloscopy even if the values are lower than in the initial bacilloscopy. We report the case of a 48-year old woman with long-standing lepromatous leprosy of 15 years of evolution, with a bacterial index of 4 in the direct smear and the initial skin biopsy. The patient was treated with multidrug therapy for 32 months although the treatment recommended by the World Health Organization (WHO) is only for 12 months. A skin biopsy was taken to determine if there was an active disease. We observed a diffuse dermal inflammation with numerous foreign body giant cells and vacuolated macrophages (Virchow´s cells). These cells contained granular acid-fast material that was also positive with immunohistochemistry for BCG. There were fragmented bacilli and the BI was 2. These cells were also strongly positive for CD68. The biopsy was interpreted as a residual form of lepromatous leprosy that did not require further multidrug therapy. We have observed similar histological profiles in several cases. The lack of clinical data makes it a histological challenge. The accumulation of lipids in these giant cells is due to bacillary destruction and fusion of vacuolated macrophages. We discuss here the role of bacillary and host lipids in the pathogenesis of lepromatous leprosy. We concluded that there was no need to extend the 12-month multidrug therapy recommended by WHO.

Los pacientes con lepra lepromatosa (LL) que han recibido tratamiento durante años, usualmente tienen seguimiento con biopsias de piel para lesiones persistentes o con baciloscopia positiva, con valores menores a los iniciales. Presentamos una mujer de 48 años con LL de 15 años de evolución, con índice bacilar (IB) 4 en el extendido directo y en la biopsia, que recibió terapia multidroga durante 32 meses, aunque el tratamiento recomendado por la Organización mundial de la salud (OMS) es de 12 meses. Se tomó una biopsia de piel para determinar si la enfermedad estaba activa. Se observó inflamación dérmica difusa con numerosas células gigantes tipo cuerpo extraño y macrófagos vacuolados (células de Virchow). Estas células, CD68 positivas, contenían material granular ácido-alcohol resistente, positivo con inmunohistoquímica para BCG. Se encontraron bacilos fragmentados y el IB fue de 2. Se interpretó como una forma residual de LL y que la paciente no requería MDT adicional. Este perfil histológico lo hemos observado en casos similares. Sin datos clínicos estas biopsias son un reto diagnóstico. La acumulación de lípidos en estas células gigantes se debe a la destrucción bacilar y a la fusión de macrófagos vacuolados. Revisamos el papel de los lípidos del bacilo y del huésped en la patogénesis de la LL. En estos casos no es necesario extender los 12 meses de MDT recomendados por la OMS. En el seguimiento de los pacientes se recomienda contar con los hallazgos clínicos, la baciloscopia, la biopsia anual de piel y los títulos IgM anti-glicolípido fenólico.

Lepra histioide o de Wade: Presentación de un caso clínico / Wade histioid leprosy: A case report

La lepra histioide de Wade, es una forma clínico-histopatológica especial de lepra multibacilar, caracterizada por la presencia de tubérculos (lesiones papulosas o nodulares) correspondientes a lepromas formados por histiocitos de morfología fusiforme. La misma es una variante infrecuente de lepra lepromatosa, que se desarrolla generalmente como recaída, en pacientes que recibieron monoterapia con dapsona, aunque se reportó su presentación de novo. En el presente trabajo, se comunica el caso clínico de una paciente de sexo femenino de 45 años de edad, con diagnóstico tardío de lepra histioide. Además, se examinan las características principales de esta forma particular de expresión de la lepra, sus diferencias con la forma clásica de presentación, los diagnósticos diferenciales que deben considerarse y la importancia de tener a esta patología entre las sospechas diagnósticas, para comenzar el tratamiento adecuado y evitar su propagación.

Wade's hystioid leprosy is a special clinical-pathological form of multibacillary leprosy, characterized by papular and nodular lepromas that consist of spindle histiocytes. It is a variant of lepromatous leprosy. Most of the cases have been related to dapsone resistance in the context of longterm monotherapy. De novo cases, not associated with previous anti-leprosy treatment, have been less frequently reported. This article presents the case of 45 years old female, with late diagnosis of histoid leprosy. There will be explained the main features of this particular form of leprosy, its differences with the classic presentation, the differential diagnoses to be considered, and the importance of having this pathology among diagnostic suspicions to begin adecuate treatment.

Enfermedad de Hansen. Una condición emergente en Chile / Hansen disease, an emergent condition in Chile

Resumen La enfermedad de Hansen (EH) es una infección secundaria a Mycobacterium leprae, de curso crónico y que afecta preferentemente la piel y los nervios periféricos. Es una condición emergente en Chile debido a la migración humana. Presentamos un caso que afectó a un trabajador inmigrante desde Haití, que presentó antes de su arribo múltiples lesiones cutáneas en placas, con hipoestesia y madarosis unilateral. El diagnóstico de la forma multibacilar se estableció por los hallazgos clínicos, la presencia de bacilos ácido-alcohol resistentes en una muestra cutánea y la detección de células inflamatorias alrededor de los terminales nerviosos y granulomas en una biopsia de piel, desde donde se amplificaron segmentos específicos de los genes rpoB y hsp65 de M. leprae. El paciente fue tratado con el esquema combinado estándar de la OMS para la forma multibacilar durante un año, con regresión parcial de las lesiones. Durante el seguimiento se detectó por RPC una disminución del número de copias del gen rpoB de M. leprae en muestras nasofaríngeas hasta el sexto mes. El registro de enfermedades de notificación obligatoria demuestra un incremento reciente de casos de EH en Chile, todos relacionados con población migrante. La enfermedad de Hansen es una nueva condición clínica y los clínicos deben estar atentos a esta posibilidad diagnóstica. Las pruebas moleculares pueden ayudar en el diagnóstico y seguimiento.

Hansen's disease (HD) is caused by Mycobacterium leprae. It has a chronic course and preferentially affects the skin and the peripheral nerves. It's an emergent infection in Chile due to migration waves. This case report affecting a migrant worker from Haiti that presented several compatible skin lesions, with hypoesthesia and unilateral madarosis that appeared before arrival. The diagnosis of a multibacillary form was established by clinical findings, presence of fast acid bacilli on a direct skin smear, and inflammatory cell surrounding nerve endings and granulomas on skin biopsy. Besides, specific rpoB and hsp65 gene segments from M. leprae were amplified from skin samples. Patient was treated with the WHO standard combined regimen for multibacillary forms during one year showing partial regression of skin lesions. Nasopharyngeal samples showed the presence of M. leprae rpoB copies detected by PCR decreasing until six months of therapy. Notifiable diseases databases showed a recent increment of cases, all related to migrant population. Hansen's disease is a new condition in Chile and clinicians should be aware of this possibility. Molecular tools may facilitate diagnosis and follow up.

Uniform multidrug therapy for leprosy patients in Brazil (U-MDT/CT-BR): results of an open label, randomized and controlled clinical trial, among multibacillary patients

BACKGROUND: Leprosy control is based on early diagnosis and multidrug therapy. For treatment purposes, leprosy patients can be classified as paucibacillary (PB) or multibacillary (MB), according to the number of skin lesions. Studies regarding a uniform treatment regimen (U-MDT) for all leprosy patients have been encouraged by the WHO, rendering disease classification unnecessary. METHODOLOGY AND FINDINGS: An independent, randomized, controlled clinical trial conducted from 2007 to 2015 in Brazil, compared main outcomes (frequency of reactions, bacilloscopic index trend, disability progression and relapse rates) among MB patients treated with a uniform regimen/U-MDT (dapsone+rifampicin+clofazimine for six months) versus WHO regular-MDT/R-MDT (dapsone+rifampicin+clofazimine for 12 months). A total of 613 newly diagnosed, untreated MB patients with high bacterial load were included. There was no statistically significant difference in Kaplan-Meyer survival function regarding reaction or disability progression among patients in the U-MDT and R-MDT groups, with more than 25% disability progression in both groups. The full mixed effects model adjusted for the bacilloscopic index average trend in time showed no statistically significant difference for the regression coefficient in both groups and for interaction variables that included treatment group. During active follow up, four patients in U-MDT group relapsed representing a relapse rate of 2.6 per 1000 patients per year of active follow up (95% CI [0·81, 6·2] per 1000). During passive follow up three patients relapsed in U-MDT and one in R-MTD. As this period corresponds to passive follow up, sensitivity analysis estimated the relapse rate for the entire follow up period between 2·9- and 4·5 per 1000 people per year. CONCLUSION: Our results on the first randomized and controlled study on U-MDT together with the results from three previous studies performed in China, India and Bangladesh, support the hypothesis that UMDT is an acceptable option to be adopted in endemic countries to treat leprosy patients in the field worldwide.

Costos directos e indirectos del diagnóstico y tratamiento de pacientes con lepra / Direct and indirect costs of diagnosis and treatment in patients with leprosy

Se realizó un estudio descriptivo de los 32 pacientes con diagnóstico de lepra en la provincia de Santiago de Cuba durante 2013, para mostrar la incidencia de esta enfermedad, así como describir los costos directos e indirectos pertinentes para el diagnóstico y tratamiento de los afectados. En la casuística predominaron el grupo de 46 y más años de edad (78,5 por ciento) y la forma clínica multibacilar (96,8 por ciento); también se encontró que el costo de esta última fue superior, dado por $ 16385, 53 (pesos cubanos)(AU)

Histoid leprosy with giant lesions of fingers and toes / Lepra histioide con lesiones gigantes de los dedos de manos y pies

This work was conducted at the Facultad de Medicina, Universidad de La Sabana, and at the Facultad de Medicina, Universidad Surcolombiana. Histoid leprosy, a clinical and histological variant of multibacillary leprosy, may offer a challenging diagnosis even for experts. An 83-year-old woman presented with papular, nodular and tumor-like lesions of 3 years of evolution, affecting fingers, toes, hands, thighs and knees, and wide superficial ulcers in her lower calves. Cutaneous lymphoma was suspected. A biopsy of a nodule of the knee showed a diffuse dermal infiltrate with microvacuolated histiocytes, moderate numbers of lymphocytes and plasma cells. Cutaneous lymphoma was suggested. Immunohistochemistry (IHC) showed prominent CD68-positive macrophages, as well as CD3, CD8 and CD20 positive cells. Additional sections suggested cutaneous leishmaniasis. New biopsies were sent with the clinical diagnoses of cutaneous lymphoma, Kaposi´s sarcoma or lepromatous leprosy, as the patient had madarosis. These biopsies showed atrophic epidermis, a thin Grenz zone and diffuse inflammation with fusiform cells and pale vacuolated macrophages. ZiehlNeelsen stain showed abundant solid phagocytized bacilli with no globii formation. Abundant bacilli were demonstrated in the first biopsy. Histoid leprosy was diagnosed. The patient received the WHO multidrug therapy with excellent results. We concluded that Ziehl Neelsen staining should be used in the presence of a diffuse dermal infiltrate with fusiform and vacuolated histiocytes, which suggests a tumor, and an IHC particularly rich in CD68-positive macrophages; this will reveal abundant bacilli if the lesion is leprosy. A good clinical pathological correlation is essential to establish a proper diagnosis and management of the patient.

La lepra histioide es una forma de lepra multibacilar de diagnóstico clínico e histológico difícil incluso para expertos. Una mujer de 83 años se presentó a consulta con pápulas, nódulos y tumores de tres años de evolución en los dedos de manos y pies, y en manos, muslos y rodillas, así como úlceras superficiales extensas en la porción inferior de las pantorrillas, ante lo cual se sospechó linfoma cutáneo. La biopsia de un nódulo de la rodilla mostró infiltrado dérmico difuso con histiocitos microvacuolados y algunos linfocitos y plasmocitos. Se sugirió la posibilidad de un linfoma cutáneo. La inmunohistoquímica demostró macrófagos prominentes positivos para CD68 y células CD3, CD8 y CD20. Con base en los cortes adicionales de la biopsia, se sugirió la presencia de leishmaniasis cutánea. Se tomaron nuevas biopsias con las sugerencias diagnósticas de linfoma cutáneo, sarcoma de Kaposi o lepra lepromatosa, pues la paciente presentaba madarosis. Estas mostraron epidermis atrófica, una delgada zona subepidérmica de colágeno denso y dermatitis difusa con células fusiformes y algunos macrófagos vacuolados. La coloración de Ziehl-Neelsen reveló la presencia de bacilos abundantes en los macrófagos, sin tendencia a formar globias. En la primera biopsia se demostraron abundantes bacilos. Se diagnosticó lepra histioide. La paciente recibió quimioterapia antileprosa (Organización Mundial de la Salud) con resultados excelentes. Se concluyó que un infiltrado dérmico difuso con histiocitos fusiformes y algunos vacuolados, que sugiere un tumor fusocelular, cuya inmunohistoquímica sea particularmente rica en células positivas para CD68, debe teñirse con Ziehl-Neelsen, lo que revelará abundantes bacilos si la lesión es de lepra. La adecuada correlación clínico-patológica es necesaria para establecer el diagnóstico y el manejo preciso del paciente.

Hanseníase multibacilar em paciente transplantado renal: relato de caso / Multibacillary leprosy in a renal recipient patient: a case report

O Brasil é um país onde a hanseníase ainda é um problema de saúde pública, apresentando mais de 30.000 novos casos por ano nos últimos anos. Apesar do crescente número de transplante de órgãos sólidos realizados no país, sobretudo o transplante renal, não são frequentes os relatos dessa micobacteriose em pacientes imunossuprimidos pelas medicações póstransplante. Os autores relatam um caso de hanseníase multibacilar manifestada 12 anos depois do transplante renal, acompanhado desde o diagnóstico, durante a poliquimioterapia, tratamento e seguimento do eritema nodoso hansênico.

Leprosy is still a public health concern in Brazil, where more than 30,000 new cases are detected every year. There are few reports of this mycobacteriosis in imunossupressed pacients, despite the increasing number of solid organ transplantation and the use of post-transplant drugs in this country. The autors describe a case of multibacillary leprosy in a renal transplant recipient, detected 12 years after the procedure, and discuss the therapy, adverse effects and management of leprosy reactions in pacients imunosupressed by drugs.

Comportamiento de la lepra en la provincia de Las Tunas 2003-2012 / Behavior of Leprosy in Las Tunas province 2003-2012

Se realizó un estudio descriptivo de corte transversal, para determinar algunas características epidemiológicas de la incidencia de la lepra, que es una enfermedad transmisible, tan antigua como el hombre mismo. El universo estuvo constituido por los 103 casos notificados con lepra en la provincia de Las Tunas, en el período de enero de 2003 a diciembre de 2012. La información se obtuvo por las encuestas epidemiológicas existentes en el Departamento de Estadística de la Dirección Provincial de Salud y en el Centro Provincial de Higiene, Epidemiología y Microbiología. Se creó una base de datos en Epinfo versión 3.3.3, donde se tabularon los datos de las encuestas. El análisis de los resultados se expresó en números absolutos, tasas y porcentajes para su mejor interpretación, obteniéndose como resultado que la tasa de detección de casos tiene un comportamiento irregular, el año de mayor incidencia fue el 2009, con 20 casos. Se notificaron tres casos de lepra infantil; las formas paucibacilares representaron el 51,5 por ciento; el modo de detección más frecuente fue el espontáneo. Existe transmisión activa y todo ello puede ser reflejo de la ausencia de un trabajo consolidado en el programa de control de la enfermedad (AU)

A descriptive, cross sectional study was carried out to determine some of the epidemiological characteristics of the incidence of leprosy, which is a transmissible disease, as old as humankind. The universe was made up of the 103 notified leprosy cases in Las Tunas province from January, 2003 to December, 2012. The information was obtained from the epidemiological surveys in the Statistic Department of the Provincial Direction of Health in Las Tunas, and in the Provincial Epidemiology and Microbiology Hygiene Center. A data base was created in Epinfo version 3.3.3, where the information from the surveys was arranged in tables. The analysis of the results were expressed in absolute numbers, rates and percentages for its better interpretation, getting as results that the rate detection of the cases has an irregular behavior, and 2009 was the year with a greater incidence, with 20 cases. Three cases of infantile leprosy were notified; the paucibacillary forms represented the 51,5 percent; the most frequent way of detection was the spontaneous one. There is active transmission of the disease, which can be because of lack of a consolidated work in the program for control of the disease (AU)

Associações de variáveis investigadas pela prova de Goodman para contraste entre e intra populações multinomiais e pelo teste não-paramétrico de Mann-Whitney, ao nível de 5% de significância. Resultados: Averiguaram-se 57 casos novos, obtendo-se 14 paucibacilares e 43 multibacilares com indicadores compatíveis com o esperado. No entanto, constataram-se, entre as inconsistências apuradas: i) cinco registros de recidiva, os quais não se confirmaram nosograficamente; ii) caso multibacilar tratado como paucibacilar; iii) quanto a modo de detecção, frequências assemelhadas de encaminhamento e demanda espontânea entre os multibacilares; iv) predomínio de grau zero de incapacidade entre paucibacilares, majoritariamente tuberculóides. Conclusões: Estes resultados indicam a necessidadede vigilância epidemiológica permanente visando à interlocução entre a rede básica e os centros de referência quanto aos procedimentos de controle, com vistas à adequação da gestão técnica dos respectivos Serviços de Saúde.

Study design: Cross sectional descriptive observational study. Introduction: Present strategy for leprosy control according to World Health Organization is based on respective treatment for pauci or multibacillary patients. Objectives: To compare leper’s profiles cared by an university hospital. Materials and Method: Data collected from Leprosy Notification Protocols, Information System for Notifiable Diseases, Celso Pierro Hospital and Maternity, PUC Campinas, years 2007 to 2011. Registers on codified sheets, storagein specific data base and statistical processing by SPSS program. Associations by Goodman’s test for contrasts among multinomial populations and by non-parametric Mann-Whitney’s, at 5% significance level. Results: 57 new cases have been ascertained, 14 paucibacillary and 43 multibacillary, showing clinical epidemiologic behaviors as expected. Nevertheless, inconsistencies have been observed, as: i) five cases of relapse registered, but not clinically confirmed; ii) a multibacillary case treated as paucibacillary; iii) in relation to forms of detection, similar frequencies of recommendation and spontaneous demand in the multibacillary group; iv) predominance of grade zero disabilities in the paucibacillary group. Conclusions: Results point to the necessity of permanent epidemiological surveillance on leprosy control in order to keep enough dialogue between basic units and reference centers.

Reação reversa macular da hanseníase: relato de caso / Macular reversal reaction in leprosy: a case report

A reação reversa maculosa consiste no aparecimento abrupto de máculas hipocrômicas, ocorrendo em pacientes hansenianos dimorfos que completaram o tratamento com poliquimioterapia para hanseníase multibacilar. Em geral, surgem entre 6 a 12 meses da alta, com baciloscopia negativa e boa resposta a corticoterapia sistêmica. Ressaltamos a dificuldade em diferenciar recidiva de um episódio reacional, já que não existem critérios clínicos bem estabelecidos que possibilitem este diagnóstico, além de existirem poucos relatos em literatura. Relatamos um caso clínico com diagnóstico de reação reversa macular após período variável de alta do tratamento de hanseniase dimorfa-dimorfa. Foi feita investigação por meio de anamnese rigorosa, exame dermatológico, exame histopatológico da lesão e baciloscopia, excluindo-se os critérios de recidiva, além de analisados dados anteriores do prontuário.O paciente foi submetido a corticoterapia sistêmica,apresentando melhora das lesões. Conclui-seque a reação reversa maculosa deve ser lembrada nos diagnósticos diferenciais com hanseníase recidivada e episódios reacionais clássicos, evitando retratamentos desnecessários.

Macular reversal reaction is the abrupt onset of hypochromic lesions, occurring in borderline leprosy patients who completed treatment with multidrugtherapy for multibacillary leprosy. In general, these reactions appear 6 to 12 months after medical discharge, showing negative skin smear and good response to systemic corticosteroid therapy. We emphasize the difficulty in differentiating relapse cases from leprosy reactions, as there are no well-established clinical criteria that allow this diagnosis, and moreover there are few reports about it in the literature. We report a borderline leprosy case diagnosed with macular reversal reaction after variable period of discharge from treatment. Detailed anamnesis, dermatological and histopathological examination and bacilloscopy, analysis of previous medical records, excluding the relapse criteria, were used for the investigation. The patient was submitted to systemic corticosteroid therapy, with improvement of the lesions. It is concluded that macular reversal reaction should be considered in the differential diagnosis of relapsed leprosy and classic reactional episodes, avoiding unnecessary retreatment.

Understanding the type 1 reactional state for early diagnosis and treatment: a way to avoid disability in leprosy / Compreender melhor o estado reacional tipo 1 para o diagnostico e tratamento precoces: uma forma de se evitar as incapacidades na hanseniase

A type 1 reaction or reversal reaction is expressed clinically by inflammatory exacerbation of the skin lesions and nerve trunks, consequently leading to sensory and motor alterations. It occurs in non-polar forms of leprosy, although it can occur in a small percentage of sub-polar LL treated patients. Disabilities, deformities and morbidity, still present in leprosy, are mainly caused by these acute episodes. The recognition of reactional states is imperative for an early approach and efficient management, to avoid the emergence of disabilities that stigmatize the disease. This review aims to describe the clinical aspects, immunopathogenesis, epidemiology, histopathological features and therapeutics of type 1 reactions.

A reação do tipo 1 ou reação reversa expressa-se clinicamente por uma exacerbação inflamatória das lesões de pele e de troncos nervosos, levando a alterações sensitivas e motoras. Ocorre nas formas não-polares da hanseníase, embora possa ocorrer numa pequena percentagem de pacientes LL tratados. As incapacidades físicas, deformidades e morbidade, ainda presentes na hanseníase, são causadas principalmente por esses episódios agudos. O reconhecimento dos estados reacionais é imperativo para uma abordagem precoce e manejo adequado, evitando a instalação de incapacidades que tanto estigmatizam a doença. Esta revisão tem como objetivo descrever aspectos clínicos, imunopatogênese, epidemiologia, características histopatológicas e terapêutica do estado reacional do tipo 1.
