ABSTRACT

Abstract Histoid leprosy is a rare form of multibacillary leprosy, characterized by the presence of papules, plaques, or nodules whose appearance is keloid-like, skin colored, or erythematous. Fusiform cells are the main histopathological feature. Due to the fact that it can simulate other dermatological lesions, for example, dermatofibroma and neurofibroma, it constitutes a diagnostic challenge for clinicians and pathologists. It is a bacilliferous form of leprosy, and it plays an important role in disease transmission. A case of a patient with histoid leprosy living in the Northeast Region of Brazil is reported.

ABSTRACT

ABSTRACT Rapidly progressive glomerulonephritis (RPGN) is a renal disease with an extensive differential diagnosis. This paper reports the case of a 55-year-old female patient diagnosed with Hansen's disease with acute progressive renal impairment after developing lower limb pyoderma. The association between Hansen's and kidney disease has been well documented, with glomerulonephritis (GN) ranked as the most common form of renal involvement. Post-infectious glomerulonephritis (PIGN) in adults has been associated with a number of pathogens occurring in diverse sites. The patient described in this case report had RPGN and biopsy findings suggestive of PIGN with C3 and IgA detected on immunofluorescence and kidney injury secondary to recent infection by Staphylococcus, a well-documented manifestation of renal impairment in patients with Hansen's disease.


RESUMO A Glomerulonefrite Rapidamente Progressiva (GNRP) é um padrão de doença renal com amplo diagnóstico diferencial. O caso reporta uma paciente de 55 anos com deterioração aguda e progressiva da função renal após quadro de piodermite em membro inferior com diagnóstico concomitante de hanseníase. Associação da hanseníase com doença renal é bem descrita, sendo a GN a forma de acometimento renal mais comum. As glomerulonefrites pós-infecciosas (GNPIs) em adultos ocorrem devido a um grande número de patógenos, nos mais diversos sítios. A paciente do caso relatado apresentava quadro de GNRP e achados de biópsia que sugerem GNPI com marcação de C3 e IgA na imunofluorescência, sugestiva de lesão renal secundária a infecção recente por Staphylococcus, uma manifestação bem descrita de doença renal em pacientes com hanseníase.

Objective: to describe the trend and the spatial distribution of leprosy in the state of Bahia, Brazil, 2001-2015. Methods: this was a mixed ecological study of epidemiological indicators of leprosy; Jointpoint regression was used for the temporal analysis, while spatial scan statistics were used to identify clusters of the disease; the trend was classified as stationary, increasing or decreasing; we calculated the annual percent change (APC) and average annual percent change (AAPC). Results: there was a reduction in prevalence (AAPC = -5.6; p<0,001), treatment dropout (AAPC = -13.7; p<0.001), and females with leprosy (AAPC = -0.6; p<0.001); the new grade II case coefficient (AAPC = 2.7; p<0.001) and the proportion of multibacillary cases (AAPC = 2,2; p<0.001) showed a growing trend; spatial distribution was heterogeneous and concentrated in three regions in particular (north, west and south of the state), with variation between the indicators. Conclusion: persisting leprosy transmission in the state, late diagnosis and high hidden prevalence is suggested.

ABSTRACT

Introdução: A hanseníase é de grande importância para a saúde pública, devido à sua epidemiologia e a seu poder incapacitante. A eficiência no diagnóstico desta doença é limitada. O objetivo deste estudo foi o de analisar o desempenho de um teste rápido imunocromatográfico para hanseníase multibacilar (MB) e paucibacilar (PB), em amostras positivas e negativas pela baciloscopia de raspado dérmico em pacientes diagnosticados com hanseníase, comparando analiticamente com os critérios da Organização Mundial da Saúde (OMS). Métodos: O estudo foi realizado no município de Ji-Paraná/RO, entre 2015 e 2016, sendo avaliados 140 indivíduos. A análise comparativa entre os métodos foi realizada pelo cálculo de sensibilidade e especificidade utilizando o software SPSS®. Foi estimado o índice de Kappa (k) para avaliação da concordância entre os métodos. Valores de p <0,05 foram considerados significativos. Resultados: O índice de concordância entre o teste rápido e a classificação da OMS foi de k= 0,94 (p <0,01). Quando comparado a baciloscopia de indivíduos com hanseníase PB e o teste rápido, foi verificada concordância não significante (k= 0,01; p= 0,59). Comparando a concordância entre a baciloscopia de indivíduos com hanseníase MB e o teste rápido, foi detectado um índice de k= 0,64 (p <0,01). Além disso, sensibilidade de 94% e especificidade de 98% foram detectadas para hanseníase PB. Para hanseníase MB a sensibilidade foi de 95% e a especificidade de 98%. Conclusão: O teste rápido avaliado é uma ferramenta útil, rápida e eficaz no auxílio do diagnóstico da hanseníase. (AU)


Introduction: Leprosy is of great importance for public health because of its epidemiology and disabling power. Efficiency in the diagnosis of this disease is limited. The objective of this study was to evaluate the performance of a rapid immunochromatographic test for multibacillary (MB) and paucibacillary (BP) leprosy, in positive and negative samples by skin smear examination in patients with leprosy, and to compare the rapid test analytically with World Health Organization (WHO) criteria. Methods: The study was conducted in the municipality of Ji-Paraná/RO, Brazil, between 2015 and 2016. In total, 140 individuals were evaluated. For a comparative analysis of the methods, sensitivity and specificity were calculated using SPSS® software. The Kappa (k) index was used to evaluate agreement between the methods. A p-value < 0.05 was considered significant. Results: Regarding agreement between the rapid test and WHO classification, k index was 0.94 (p < 0.01). When skin smear of individuals with BP leprosy was compared to the rapid test, agreement was non-significant (k = 0.01; p = 0.59). For agreement between skin smear of individuals with MB leprosy and the rapid test, a k index of 0.64 (p < 0.01) was detected. In addition, for PB leprosy sensitivity was 94% and specificity was 98%, while for MB leprosy sensitivity was 95% and specificity was 98%. Conclusion: The rapid test is a useful tool, fast and effective in aiding the diagnosis of leprosy. (AU)

ABSTRACT

BACKGROUND Leprosy remains a health problem in many countries, with difficulties in diagnosis resulting in delayed treatment and more severe disabilities. Antibodies against several Mycobacterium leprae antigens have, however, shown value as diagnostic and/or prognostic markers. OBJECTIVES The objective of this study was to evaluate serum immunoglobulin (Ig) IgM and IgG subclass reactivity against three M. leprae specific antigens: NDO-HSA, a conjugate formed by natural octyl disaccharide bound to human serum albumin; LID-1, the fusion protein product of the ml0405 and ml2331 genes; and NDO-LID, a combination of LID-1 and NDO. METHODS Sera from healthy controls, paucibacillary (PB) and multibacillary (MB) leprosy patients, and their respective household contacts, were evaluated for the presence of antigen-specific IgM, IgG, and IgG subclass antibodies by enzyme-linked immunosorbent assay (ELISA). The sensitivity and specificity of each ELISA were evaluated by receiver operating characteristic (ROC) curve analysis. FINDINGS Our data confirm that serum IgM antibodies against NDO-HSA and IgG antibodies against LID-1, as well as IgG/M antibodies against NDO-LID, are markedly increased in MB patients. For the first time, our data reveal a selective increase in IgG1 and IgG3 antibodies against LID-1 and NDO-LID in MB patients, demonstrating that these antibody isotypes are suitable for differentiation between MB and PB patients. ROC curve analysis indicates an improved capacity for diagnosing MB leprosy patients using the detection of IgG antibodies, particularly the IgG1 isotype, specific to LID-1 and NDO-LID over the performance levels attained with NDO-HSA. CONCLUSIONS Our findings indicate that serological tests based on the detection of antigen-specific IgG1 antibodies are a useful tool to differentiate MB from PB patients, and indicate the enhanced performance of the LID-1 and NDO-LID antigens in the serodiagnosis of leprosy.

ABSTRACT

Abstract Considering that the main route of Mycobacterium leprae transmission is the upper respiratory tract, detection of salivary antibodies can be a useful tool for diagnosing early infection. The study aimed to analyze salivary anti-PGL-1 IgA and IgM antibodies in 169 children aged 4-16 years old, who lived nearby or inside the house of multibacillary or paucibacillary leprosy patients in two endemic cities in Alagoas State - Brazil. Salivary anti-PGL-1 antibodies were quantified by modified ELISA method. The frequency of contact and clinical form of the index case were significantly associated with salivary antibody levels. High frequency of IgM positivity strongly suggests active transmission of M. leprae in these communities. We suggest in the present work that salivary anti-PGL IgA and IgM are important biomarkers to be used for identifying communities with probable active transmission of M. leprae.

ABSTRACT

Abstract Wade's histoid leprosy (HL) is a rare variant of multibacillary leprosy, with characteristic clinical, immunologic, histopathologic, and bacteriologic features. It is associated with resistance to sulfa drugs or polychemotherapy and is rarely observed in patients who have not undergone prior treatment. Clinically, HL resembles keloid or dermatofibroma. Furthermore, HL is rare in children and is difficult to diagnose even by experts. This report describes a case of HL in a 14-year-old Brazilian boy, who presented with multiple nodular and tumor-like lesions, simulating keloids. He had not undergone prior treatment with anti-leprosy drugs, which accentuates the relevance of this case report.

ABSTRACT

Abstract INTRODUCTION: Currently, there are no laboratory tests or sensitive and specific molecular markers for the early diagnosis of leprosy. The aim of this study was to analyze the clinical characteristics of patients with leprosy and investigate their immunological profile, comparing this with the type of lesion and the presence or absence of a Bacillus Calmette-Guérin (BCG) vaccination scar. METHODS: Statistical analyzes were performed by employing comparative tests (Pearson´s chi-square) to evaluate the variables in different clinical forms, considering significance at the 5% level. RESULTS: The study identified a predominance of lepromatous leprosy (26.9%) in patients aged between 34-53 years. Caucasians predominantly had borderline tuberculoid (BT) clinical forms (42%); a predominance of males with borderline lepromatous (19%) and lepromatous leprosy (26.9%) forms was observed; and the presence of BCG vaccination scars (27.5%) and lower limb nerves were more affected (38%) predominantly in the BT clinical form. Significant differences were identified, which included hypochromic lesions predominantly in the BT clinical form (24%); diffuse-type lesions predominantly in the tuberculoid (TT) clinical form (28%); ill-defined lesion border dominance in lepromatous leprosy (LL) clinical forms (30%); an irregular lesion limit predominantly in LL clinical forms (32%); and a predominant Th1 immune response in the BT clinical form (41.7%). CONCLUSIONS: The evaluation of the immunological profile in leprosy patients may contribute to the more detailed diagnosis and possibly better characterization of the prognosis for these individuals.

ABSTRACT

Abstract Leprosy is a chronic disease characterized by manifestations in the peripheral nerves and skin. The course of the disease may be interrupted by acute phenomena called reactions. This article reports a peculiar case of type 2 leprosy reaction with Sweet's syndrome-like features as the first clinical manifestation of leprosy, resulting in a delay in the diagnosis due to unusual clinical presentation. The patient had clinical and histopathological features reminiscent of Sweet's syndrome associated with clusters of vacuolated histiocytes containing acid-fast bacilli isolated or forming globi. Herein, it is discussed how to recognize type 2 leprosy reaction with Sweet's syndrome features, the differential diagnosis with type 1 leprosy reaction and the treatment options. When this kind of reaction is the first clinical presentation of leprosy, the correct diagnosis might be not suspected clinically, and established only with histopathologic evaluation.

ABSTRACT

Leprosy inflammatory episodes [type 1 (T1R) and type 2 (T2R) reactions] represent the major cause of irreversible nerve damage. Leprosy serology is known to be influenced by the patient’s bacterial index (BI) with higher positivity in multibacillary patients (MB) and specific multidrug therapy (MDT) reduces antibody production. This study evaluated by ELISA antibody responses to leprosy Infectious Disease Research Institute diagnostic-1 (LID-1) fusion protein and phenolic glycolipid I (PGL-I) in 100 paired serum samples of 50 MB patients collected in the presence/absence of reactions and in nonreactional patients before/after MDT. Patients who presented T2R had a median BI of 3+, while MB patients with T1R and nonreactional patients had median BI of 2.5+ (p > 0.05). Anti-LID-1 and anti-PGL-I antibodies declined in patients diagnosed during T1R (p < 0.05). Anti-LID-1 levels waned in MB with T2R at diagnosis and nonreactional MB patients (p < 0.05). Higher anti-LID-1 levels were seen in patients with T2R at diagnosis (vs. patients with T1R at diagnosis, p = 0.008; vs. nonreactional patients, p = 0.020) and in patients with T2R during MDT (vs. nonreactional MB, p = 0.020). In MB patients, high and persistent anti-LID-1 antibody levels might be a useful tool for clinicians to predict which patients are more susceptible to develop leprosy T2R.

ABSTRACT

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.

ABSTRACT

Mycobacterium leprae was first described as the bacillus that causes leprosy, a chronic granulomatous infectious disease, in 1873 by Amauer Hansen. Leprosy is part of a group of 10 neglected diseases and Bahia has endemic levels of this illness, varying between high and very high. The detection of 52 new cases of leprosy in children under 15 years old in Salvador in 2006 is alarming, and suggests an early contact with the disease. The aim of this review is to analyze the epidemiological situation, the detection rate and evaluate the clinical and epidemiological profile of leprosy in Salvador, in the period 2001-2009. A retrospective cross-sectional study was performed using secondary data collected at Notifiable Diseases Information System Database (SINAN) through the notification of patients with leprosy. Over these nine years 3,226 patients were reported, with a predominance of: females (51.5%), and clinical multibacillary forms in the general population (51.7%), but when we analyze those under 15 years old, paucibacillary forms (tuberculoid + indeterminate) prevailed. The tuberculoid form was the most diagnosed type of presentation. The annual detection rate in Salvador remained at a very high level of endemicity during the studied period and for those under 15 years old it ranged between high and very high. Grade 2 disabilities both at the time of diagnosis and at discharge after cure, varied between low and medium. Based on these data we conclude that the high levels of leprosy detection rates in the general population, plus the variation between high and very high levels in those under 15 years old, associated with the medium level of grade 2 disabilities at the time of diagnosis and discharge, demonstrate the need for improvement on the existing services, investment in active case finding and training of the healthcare professionals in Salvador.

ABSTRACT

Em 1963, Wade descreveu a hanseníase histoide, que acometia pacientes previamente tratados com dapsona.Caracteriza-se por lesão com aspecto queloideano, na histopatologia vemos histiócitos fusiformes e um grande número de bacilos. Relata-se caso de hanseníase dimorfa virchoviana com padrão de lesão históide, um verdadeiro desafio diagnóstico, a fim de atentar para manifestações atípicas dessa doença e reforçar a importância da confirmação histológica de casos suspeitos de hanseníase históide.


In 1963, Wade described Histoid Leprosy, that affected patients previously treated with dapsone. This type of leprosy is characterized by keloid-like lesions, in which spindle histiocytes and a large number of bacilli can be seen in the histopathology. A case of borderline lepromatous leprosy with histoid pattern is described, a true diagnostic challenge, in order to attempt to atypical manifestations of the disease and reinforce the importance of histological confirmation in suspected cases of histoid leprosy.

ABSTRACT

Leprosy is a disease caused by Mycobacterium leprae that carries a high risk of disability, making early diagnosis mandatory. This study aimed to determine the applicability of anti-PGL-1 IgM antibody detection, using the ML FLOW technique, as an assistant tool for the detection of leprosy infection in asymptomatic household contacts (AHHC) of multibacillary leprosy index cases from Midwest Brazil. Serological changes induced by the prophylaxis of these household contacts with Bacillus Calmette-Guérin (BCG) were also verified. A total of 91 AHHC were assessed, among which, 18.68% (n = 17) presented both positive bacilloscopy and positive anti-PGL-1 IgM serology. Positivity concordance between these two laboratorial exams (Kappa Index = 1; p < 0.001) was indicated, however, one case did not demonstrate concordance between the semiquantitative assessment of anti-PGL-1 IgM and the bacilloscopy index (Kappa Index = 0.96; p < 0.001). Among the 17 AHHC with positive bacilloscopy, eight were reassessed after prophylaxis with BCG and two of them presented negative anti-PGL-1 IgM serology, being these patients who had presented a bacilloscopy index of < 2[+] in the initial assessment. This study shows that anti-PGL-1 IgM detection may be used as a tool to determine the bacillary load in AHHC and to detect immune changes related to prophylaxis by nonspecific vaccination.


A hanseníase é doença causada pelo Mycobacterium leprae, apresentando elevado potencial incapacitante, o que torna indispensável seu diagnóstico precoce. O estudo visa determinar a aplicabilidade da detecção de anticorpos anti-PGL1-IgM por meio da técnica do ML FLOW como ferramenta adjuvante ao diagnóstico de hanseníase em contatos domiciliares assintomáticos (AHHC) de pacientes multibacilares procedentes da região Centro-Oeste do Brasil, bem como, documentar o comportamento sorológico após a profilaxia com a vacina Bacillus Calmette-Guérin (BCG). Foram avaliados 91 AHHC atendidos no Hospital Universitário de Brasília - Brasil, dos quais 18,68% (n = 17) apresentaram positividade para baciloscopia e anti-PGL1-IgM, totalizando uma concordância completa entre os dois grupos (Índice Kappa = 1; p < 0,001). Em apenas um dos casos não observou-se concordância entre a avaliação semi-quantitativa do anti-PGL1-IgM e índice baciloscópico (Índice Kappa = 0,96; p < 0,001). Oito dos 17 AHHC com baciloscopia positiva foram reavaliados após profilaxia com BCG e apenas dois apresentaram negativação dos títulos anti-PGL1-IgM, sendo tais casos correspondentes aos que haviam apresentado índice baciloscópico menor do que 2[+] na avaliação inicial. O estudo corrobora o potencial do anti-PGL1-IgM como ferramenta de predição da carga bacilar em AHHC da região Centro-Oeste do Brasil, e surpreende alterações imunes relacionadas à profilaxia obtida pela vacinação não específica com BCG.

ABSTRACT

Leprosy in children is correlated with community-level factors, including the recent presence of disease and active foci of transmission in the community. We performed clinical and serological examinations of 1,592 randomly selected school children (SC) in a cross-sectional study of eight hyperendemic municipalities in the Brazilian Amazon Region. Sixty-three (4%) SC, with a mean age of 13.3 years (standard deviation = 2.6), were diagnosed with leprosy and 777 (48.8%) were seropositive for anti-phenolic glycolipid-I (PGL-I). Additionally, we evaluated 256 house-hold contacts (HHCs) of the students diagnosed with leprosy; 24 (9.4%) HHC were also diagnosed with leprosy and 107 (41.8%) were seropositive. The seroprevalence of anti-PGL-I was significantly higher amongst girls, students from urban areas and students from public schools (p < 0.0001). Forty-five (71.4%) new cases detected amongst SC were classified as paucibacillary and 59 (93.6%) patients did not demonstrate any degree of physical disability at diagnosis. The results of this study suggest that there is a high rate of undiagnosed leprosy and subclinical infection amongst children in the Amazon Region. The advantages of school surveys in hyperendemic areas include identifying leprosy patients at an early stage when they show no physical disabilities, preventing the spread of the infection in the community and breaking the chain of transmission.

ABSTRACT

Leprosy is a slowly evolving disease that occurs mainly in adults. In this study, the Mamaría Village, state of Portuguesa was selected because it had one of the highest prevalence rates (13.25%) of leprosy cases in 1997. Between 1998-2004, 20.2% of the 89 cases registered in this village were less than 15 years old and 61.8% were males. Pau-cibacillary (PB) lesions were the predominant clinical forms identified, although also multibacillary (MB) forms were found. Additionally, 76% of the patients were bacteriologically negative. At the time of diagnosis, 75% of the patients presented with grade 0 disabilities, 23% with grade 1 and 2% with grade 2. Serum samples were collected from 18 PB and 15 MB patients, in addition to 14 family contacts, at the beginning and end of treatment. All the groups were re-evaluated during a three-year period (2008-2011). The proteins used for evaluation were ML0405, ML2331 and LID-1. These mycobacterial proteins were highly specific for Mycobacterium leprae and the IgG responses decreased in both MB and PB patients during multidrug treatment. Our results suggest that these antigens could be used as markers for successful treatment of non-reactional lepromatous patients.
