Case for diagnosis. Erythematous and infiltrated plaques in the infrahyoid region

Abstract Leprosy is a chronic infectious disease caused by Mycobacterium leprae and, depending on the host immune status, presents different clinical forms. This report describes the case of a 46-year-old man who had hypoesthetic lesions in the infrahyoid region for 30 days. The bacilloscopy was negative. The anatomopathological examination showed alterations corresponding to the tuberculoid pole (epithelioid histiocytes) and virchowian pole (foamy histiocytes), compatible with borderline-virchowian leprosy (Ridley and Jopling classification). Rapid tests for HIV I, II, and syphilis were positive, with a CD4 count of 223. The patient started treatment with multibacillary multidrug therapy, antiretroviral therapy, and benzathine penicillin, with marked clinical improvement in two months.

Case for diagnosis. Infiltrated areas on the trunk

Abstract Leprosy is an infectious disease with chronic evolution, caused by Mycobacterium leprae, an acid-fast bacillus that mainly affects the skin and peripheral nervous tissue. Many of the clinical manifestations of leprosy can mimic connective tissue diseases. The authors present the case of a 49-year-old woman who had been treated for four years for systemic lupus erythematosus in a rheumatological service. Skin biopsy of a plaque on the inguinal region was compatible with borderline lepromatous leprosy associated with a type 1 lepra reaction. The patient is undergoing treatment with multibacillary multidrug therapy, showing clinical improvement.

The challenge of concomitant infections in the coronavirus disease 2019 pandemic era: Severe acute respiratory syndrome coronavirus 2 infection in a patient with chronic Chagas disease and dimorphic leprosy

Abstract Coronavirus disease 2019 (COVID-19) was first officially described in Brazil on February 26th, 2020. The accumulation of reports of concomitant infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and pathogens that cause diseases endemic to tropical countries, such as dengue and chikungunya fever, has started to draw attention. Chagas disease and leprosy remain public health problems in many developing countries, such as Brazil. In this manuscript, we describe a case of concomitant leprosy, Chagas disease, and COVID-19, highlighting the cutaneous manifestations of SARS-CoV-2 infection and the clinical behavior of household contacts who previously received prophylactic Bacillus Calmette-Guérin vaccines.

Aspectos clínicos y epidemiológicos en pacientes timorenses con enfermedad de Hansen / Clinical and epidemiological aspects in Timor patients with the Hansen disease

Se realizó un estudio observacional, descriptivo y transversal de 14 pacientes con lepra, diagnosticados y atendidos en la consulta de Dermatología del Hospital Nacional Guido Valadares, en Dili, Timor Oriental, de julio a diciembre del 2015, con vistas a caracterizarles y describir algunos aspectos clínicos y epidemiológicos de la enfermedad. En la serie se obtuvo una mayor frecuencia de pacientes en el grupo etario de 26 a 35 años y del sexo masculino, la forma clínica predominante fue la multibacilar y el tiempo de evolución de los síntomas hasta que fuera establecido el diagnóstico fue de menos de un año. Igualmente, en la mayoría existieron reacciones agudas, principalmente de tipo II o eritema nudoso leproso, y diferentes grados de discapacidad.

An observational, descriptive and cross-sectional study of 14 patients with leprosy, diagnosed and assisted in the Dermatology Service of Guido Valadares National Hospital, in Dili, Timor Lester was carried out from July to December, 2015, with the aim of characterizing them and to describe some clinical and epidemiological aspects of the disease. In the series a higher frequency of patient was obtained in the age group 26 to 35 years and of the male sex, the predominant clinical form was the multibacilar and the time of clinical course of the symptoms up to reaching the diagnosis was shorter than a year. Equally, in most of them acute reactions were presented, mainly of type II or from the erythema leprosy group, and different degrees of inability.

Erythroderma as a manifestation of leprosy

Abstract: Erythroderma consists of erythema and scaling involving most or all of the body surface. This generalized eruption may be idiopathic, drug-induced or secondary to cutaneous or systemic disease. A 71-year-old man is reported presenting generalized erythema and desquamation with deck-chair sign, nail dystrophy, and plantar ulcers associated with loss of local tactile sensitivity. Biopsies from three different sites demonstrated diffuse lymphocytic infiltrate with incipient granulomas. Fite-Faraco staining showed numerous isolated bacilli and globi. The skin smear was positive. Clinical and pathological diagnosis of borderline lepromatous leprosy was confirmed. This report demonstrates that chronic multibacillary leprosy can manifest as erythroderma and thus should be included in the differential diagnosis.

Lepra dimorfa lepromatosa conyugal / Lepromatous dimorphic leprosy in spouses

Leprosy is a contagious, chronic infectious disease caused by Mycobacterium leprae. The immune response of the host to this bacillus is variable, determining different clinical forms of the same disease. Between the Lepromatous and Tuberculoid spectra, both stable clinical forms, the Dimorfo type can be presented, with great immunological instability, determining clinical characteristics, according to the pole to which most approaches. Leproatous dimorphic leprosy is characterized by brwn and violet macules, large number of lesions and less definition at its edges, variable sizes and alteration of sensitivity. Conjugal leprosy occurs in very few cases, knowing that intimate contaqct for a long time is an important factor, but has also demonstrated the fundamental role of immunity and genetics to acquire and develop the disease. We present two cases of lepromatous dimorphic leprosy in spouses, with 20 years of cohabitation, in which the same clinical presentation was found. Ths is an infrequent fact, given the low infectivity of the pathogen and the multiple varieties that could occur.

Sociodemographic and epidemiological profile of leprosy patients in an endemic region in Brazil

Abstract: INTRODUCTION: The incidence of Hansen's disease is high in overlooked populations. METHODS: Data of Hansen's disease cases reported in the information system of the Department of Informatics, Brazilian Unified Health System, from 2013 to 2014 were analyzed. RESULTS: Among 434 studied cases of Hansen's disease, the female sex (52.5%), adult age (73.7%), low educational level (61.8%), and multibacillary form were associated with higher prevalence rates. CONCLUSIONS: Hansen's disease is more frequent among female adults with a low educational level, and the prevalence of multibacillary leprosy reflects disease detection at late stages.

Leprosy type-I reaction episode mimicking facial cellulitis-the importance of early diagnosis

Leprosy is aneasily recognizable disease due to its dermato-neurological manifestations. It must be present in the physician’s diagnostic repertoire, especially for those working in endemic areas. However, leprosy reaction is not always easily recognized by non-dermatologists, becoming one of the major problems in the management of patients with leprosy, as it presents clinical complications characterized by inflammatory process, accompanied by pain, malaise and sometimes the establishment or worsening of the patient’s disabilities. We report the case of a patient with type-1 periorbital reaction admitted to the hospital, diagnosed and treated as facial cellulitis, whose late diagnosis may have contributed to the appearance or worsening of facial neuritis.

Prevention of repeated episodes of type 2 reaction of leprosy with the use of thalidomide 100 mg/day

BACKGROUND: Leprosy can have its course interrupted by type 1 and 2 reactional episodes, the last named of erythema nodosum leprosum (ENL). Thalidomide has been the medication of choice for the control of ENL episodes since 1965. OBJECTIVES: These episodes can repeat and cause damages to the patient. In order to prevent these episodes, an extra dose of 100 mg/day thalidomide was used during six months, followed by a follow-up period of six more months after thalidomide discontinuation. METHODS: We included 42 patients with multibacillary (MB) leprosy who had episodes of ENL. They were male and female patients aged between 18 and 84 years. RESULTS: Of the 42 patients, 39 (92.85%) had the lepromatous form and three (7.15%) had the borderline form. We found that 100% of patients had no reactional episode during the use of the drug. During the follow-up period after thalidomide discontinuation, 33 (78.57%) patients had no reactional episode and nine (21.43%), all of them with the lepromatous form, had mild episodes, which were controlled using non-steroidal anti-inflammatory. There were no thalidomide-related side effects. CONCLUSION: A maintenance dose of 100 mg/day of thalidomide showed to be effective to prevent repeated type 2 reactional episodes of ENL. .

Borderline tuberculoid leprosy and type 1 leprosy reaction in a hepatitis C patient during treatment with interferon and ribavirin / Hanseniase boderline tuberculoide e reacao hansenica do tipo 1 em paciente com hepatite C durante tratamento com interferon e ribavirina

Hepatitis C is an inflammatory disease of the liver caused by a single-stranded RNA virus belonging to the Hepacivirus genus in the Flaviviridae family, called the hepatitis C virus. After initial infection, 70% to 85% of the patients develop chronic hepatitis C with hepatic fibrosis. In addition to specific liver changes, various extrahepatic manifestations have been associated with the hepatitis C virus infection or with medications used to treat the condition. We report the case of a patient with chronic hepatitis C who presented with the signs and symptoms of borderline tuberculoid leprosy and type 1 reaction four months after the start of treatment with a pegylated interferon/ribavirin combination.

A hepatite C é uma doença inflamatória fígado causada por um vírus RNA de fita simples, pertencente ao gênero Hepacivirus e à família Flaviviridae, denominado de vírus da hepatite C. Após infecção inicial 70 a 85% dos pacientes infectados evoluem para hepatite C crônica, com fibrose progressiva. Além das alterações hepáticas específicas, várias manifestações extra-hepáticas têm sido relacionadas à infecção pelo vírus da hepatite C ou às medicações utilizadas no seu tratamento. Nesse trabalho, apresenta-se caso de paciente portador de hepatite C crônica, que manifestou um quadro hanseníase boderline tuberculóide e reação hansênica do tipo I, quatro meses após início do tratamento com interferon peguilado associado à ribavirina.

Borderline tuberculoid leprosy associated with primary cutaneous histoplasmosis / Hanseníase dimorfa tuberculoide associada à histoplasmose cutânea primária

We describe a case of borderline tuberculoid leprosy associated with primary cutaneous histoplasmosis in a patient who presented at our hospital with skin lesions and joint complaints.

Descrevemos um caso de hanseníase dimorfa tuberculoide associada à histoplasmose cutânea primária em um paciente que procurou nosso hospital com lesões dermatológicas e queixas articulares.

Use of the polymerase chain reaction to detect Mycobacterium leprae in urine

Leprosy is an infectious disease caused by Mycobacterium leprae. The polymerase chain reaction (PCR) has been applied to detect M. leprae in different clinical samples and urine seems to be attractive for this purpose. PCR was used to improve the sensitivity for diagnosing leprosy by amplifying a 151-bp PCR fragment of the M. leprae pra gene (PCR-Pra) in urine samples. Seventy-three leprosy patients (39 males and 34 females, 14 to 78 years old) were selected for leprosy diagnosis at a reference laboratory in Maringá, PR, Brazil. Of these, 36 were under anti-leprosy multidrug therapy with dapsone and rifampicin for tuberculoid (TT) and dapsone, rifampicin and clofazimine for borderline (BB) and lepromatous (LL) forms. The control group contained 50 healthy individuals without any clinical history of leprosy. DNA isolated from leprosy patients’ urine samples was successfully amplified by PCR-Pra in 46.6 percent (34/73) of the cases. The positivity of PCR-Pra for patients with the TT form was 75 percent for both patients under treatment and non-treated patients (P = 0.1306). In patients with the LL form, PCR-Pra positivity was 52 and 30 percent for patients under treatment and non-treated patients, respectively (P = 0.2386). PCR-Pra showed a statistically significant difference in detecting M. leprae between the TT and LL forms of leprosy in patients under treatment (P = 0.0033). Although the current study showed that the proposed PCR-Pra has some limitations in the detection of M. leprae, this method has the potential to be a useful tool for leprosy diagnosis mainly in TT leprosy where the AFB slit-skin smear is always negative.

Hanseníase dimorfa com acometimento articular: dificuldades no diagnóstico / Borderline leprosy with articular involvement: diagnostic difficulties

A hanseníase é doença infecciosa granulomatosa crônica causada pelo Mycobacterium leprae, um bacilo ácido-resistente com a sua predileção para afetar as áreas mais frias do corpo, como pele e nervos periféricos,o que torna o diagnóstico simples na maioria dos casos 1,2. No entanto, com base na resposta imune do paciente infectado, o envolvimento sistêmico pode ocorrer,principalmente nas formas multibacilares. Estes eventos são pouco encontrados, mas têm extrema relevância clínica devido à sua semelhança com doenças reumáticas 5, 6. Relata-se um caso de hanseníase confundida com artrite inespecífica em que o paciente apresentou inicialmente artralgia, edema das articulações, poliartrite e,finalmente, o aparecimento de lesões na pele. Em áreas endêmicas, os clínicos e reumatologistas deve sempre estar atentos sobre a hanseníase com essas manifestações iniciais.

Leprosy is a chronic caused by Mycobacterium leprae, an acid-fast bacillus with its predilection to affect the cooler areas of the body such as skin and peripheral nerves, which makes diagnosis simpler in most cases 1.2 granulomatous infectious disease . However, based on the immune response of the infected patient, systemic involvement may occur, characterized Multibacillary manner. These events are rarely found, but have extremelyclinical relevance because of its similarity with rheumatic diseases 5, 6. Report a case of leprosy confused with nonspecific arthritis in a patient who initially presented with joint pain, joint swelling, polyarthritis, and finally the appearance of skin lesions.

Early diagnosis of relapse in borderline leprosy: two case reports / Diagnóstico precoce de recidiva em hanseníase dimorfa: apresentação de dois casos

Two cases of relapse in borderline leprosy were reported. Despite the late-reversal, reaction-like feature, the suspicion of relapse in both was based on persistent and slow-developing skin lesions and an absence of acute neuritis or reaction during one year of follow-up. The authors have considered this possible occurrence in lepromatous borderline-treated patients after their immune cellular restoration and defend that not all Type 1 reactions would be an inflammatory answer to persistent Mycobacterium leprae, but that they could be. Therefore, a relapse diagnosis could be applied and it is more advisable, as one year of Multi-Drug Therapy (MDT) is less dangerous and more efficient for these cases than one year of corticosteroids.

São apresentados dois casos de recidiva de hanseníase borderline. Apesar das características de reação reversa tardia, a suspeita de recidiva foi baseada no desenvolvimento insidioso e persistente de lesões cutâneas sem reação e neurite agudas, durante um ano de seguimento. Os autores consideram a possibilidade de recidiva em pacientes borderline virchowinano tratados, pela restauração da imunidade celular e postulam que embora nem toda reação tipo 1 seja devida a presença de M. leprae persistentes, isso também pode ocorrer. Assim, o diagnóstico de recidiva foi considerado ressaltando-se que um ano de poliquimioterapia oferece menos danos e pode ser mais eficiente nesses casos, que um ano de corticosteróides.

Leprosy and multiple endocrine neoplasia type I: a case report and review of literature / Hanseníase e neoplasia endócrina múltipla tipo 1: relato de caso e revisão de literatura

Context: Leprosy is an infectious disease in which progress to disease and clinical expressions are influenced by environmental factors and by the genetics of the host. The multiple endocrine neoplasia type 1 syndrome (MEN-1) is an inherited disorder that predisposes to endocrine and non-endocrine tumors. Case report: A case of multi-bacillary leprosy in the 18-year-old female patient with MEN- 1, this association was probably an incidental case of an endemic disease in a susceptible individual with a rare syndrome. The investigation of comorbities, especially neglected or emergency disease, is very importance, because the lack of early diagnosis may result in serious complications as development of disabilities especially when there is a leprosy late diagnosis.

Contexto: A hanseníase é uma doença infecciosa cuja evolução e expressões clínicas são influenciadas por fatores ambientais e pela genética do hospedeiro. A síndrome neoplasia endócrina múltipla tipo 1 (NEM-1)é uma desordem hereditária que predispõe a tumores endócrinos e não-endócrinos . Relato de caso: Relata-se um caso de hanseníase multibacilar em paciente de 18 anos de idade com NEM- 1. Esta associação foi, provavelmente, um caso incidental de uma doença endêmica em um indivíduo suscetível com uma síndrome rara. A pesquisa de comorbidades, especialmente entre as doenças negligenciadas ou emergentes é muito importante, porque a falta de diagnóstico precoce pode resultar em complicações graves como o desenvolvimento de deficiências especialmente quando há um diagnóstico de hanseníase tardio.

Hanseníase dimorfa reacional em criança / Reactional borderline leprosy in childhood

Uma criança de 3 anos de idade recebeu o diagnóstico clínico de hanseníase multibacilar e iniciou poliquimioterapia, evoluindo após 2 meses com placas eritêmato-violáceas, foveolares, disseminadas. Sua mãe foi diagnosticada com hanseníase na faixa virchoviana há 1 ano e nesta ocasião a criança recebeu vacina BCG. A reavaliação clínica e os exames complementares da criança confirmaram hanseníase dimorfa com reação reversa,com baciloscopia de 3+, com bacilos granulosos. Este caso mostra algumas peculiaridades, como a presença de hanseníase multibacilar nesta faixa etária, fato incomum, devido ao longo período de incubação da doença; bem como demonstra que a vacina BCG não modificou a evolução natural da doença, pois a criança já apresentava a doença em fase avançada. Os autores discutem alguns aspectos da hanseníase na infância,como a epidemiologia, fatores de risco, recursos diagnóstico se reforçam a importância da avaliação e do diagnóstico precoce de crianças contactantes de portadores de hanseníase, assim como do acompanhamento regular e de medidas de prevenção de incapacidades.

A three-year-old child has received a clinical diagnosticof multibacillary leprosy and has initiated polichemotherapy,developing erythematous infiltrated plaques,with foveolar aspect, disseminated after two months.The child’s mother had received a lepromatous leprosydiagnostic a year ago and in that occasion the child receivedthe BCG vaccine. The clinical reevaluation andthe complementary exams from the child confirmedthe diagnosis of borderline leprosy with reverse reaction,bacilloscopy 3+, and granular bacilli. This caseshows some peculiarities, such as the presence of multibacillaryleprosy in this age range, an uncommon factdue to the long period of incubation of the disease, aswell as demonstrating that the BCG vaccine has notmodified the natural evolution of the disease, as thechild presented the disease in an already advancedstage. The authors discuss some aspects of the leprosyin children, e.g. epidemiology, risk factors and diagnosisresources, and reinforce the importance of an early diagnosticin children who have contact with leprosy carriers,as well as the regular management and incapacityprevention measures.

Hanseníase borderline virchowiana / Borderline lepromatous leprosy

É apresentado caso de hanseníase borderline virchowiana com quatro anos de evolução e lesões cutâneas de difícil diagnóstico na rede de saúde. O exame histopatológico mostrando estruturas granulomatosas desorganizadas e múltiplos bacilos álcool-ácido resistentes foi essencial para o diagnóstico.
