Ulcers in leprosy patients, an unrecognized clinical manifestation: a report of 8 cases.

BACKGROUND: Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae. It is a polymorphic disease with a wide range of cutaneous and neural manifestations. Ulcer is not a common feature in leprosy patients, except during reactional states, Lucio's phenomenon (LP), or secondary to neuropathies. CASES PRESENTATION: We report eight patients with multibacillary leprosy who presented specific skin ulcers as part of their main leprosy manifestation. Ulcers were mostly present on lower limbs (eight patients), followed by the upper limbs (three patients), and the abdomen (one patient). Mean time from onset of skin ulcers to diagnosis of leprosy was 17.4 months: all patients were either misdiagnosed or had delayed diagnosis, with seven of them presenting grade 2 disability by the time of the diagnosis. Reactional states, LP or neuropathy as potential causes of ulcers were ruled out. Biopsy of the ulcer was available in seven patients: histopathology showed mild to moderate lympho-histiocytic infiltrate with vacuolized histiocytes and intact isolated and grouped acid-fast bacilli. Eosinophils, vasculitis, vasculopathy or signs of chronic venous insufficiency were not observed. Skin lesions improved rapidly after multidrug therapy, without any concomitant specific treatment for ulcers. CONCLUSIONS: This series of cases highlights the importance of recognizing ulcers as a specific cutaneous manifestation of leprosy, allowing diagnosis and treatment of the disease, and therefore avoiding development of disabilities and persistence of the transmission chain of M. leprae.

Leprosy on the scalp

Abstract Leprosy is a chronic infectious disease caused by Mycobacterium leprae. This bacillus has a high predilection for skin and peripheral nerves. The scalp’s anatomical properties do not favor the development of such mycobacterium. We report a case of leprosy with scalp involvement, a rare occurrence in our literature.

Association of viable Mycobacterium leprae with Type 1 reaction in leprosy.

UNLABELLED: The working hypothesis is that, viable Mycobacterium leprae (M. leprae) play a crucial role in the precipitation of Type 1 reaction (T1R) in leprosy. MATERIAL AND METHODS: A total of 165 new multibacillary patients were studied. To demonstrate presence of viable M. leprae in reactional lesion (T1R+), three tests were used concurrently viz. growth in the mouse foot pad (MFP), immunohistochemical detection of M. leprae secretory protein Ag85, and 16s rRNA--using in situ RT-PCR. Mirror biopsies and non reactional lesions served as controls (T1R-). FINDINGS: A significantly higher proportion of lesion biopsy homogenates obtained at onset, from T1R(+) cases have shown unequivocal growth in MFP, proving the presence of viable bacteria, as compared to T1R(-) (P < 0.005). In contrast, few Mirror biopsies were positive in both T1R(+) and T1R(-). With respect to Ag85, while the overall positivity was higher in T1R(+) (74%), however the intensity of staining (Grade 2+) was disproportionately higher in T1R(+) BT-BB lesions 11/20 (55%). In the rebiopsies obtained during a repeat episode of T1R, Ag 85 as well as 16s rRNA, positivity (62% & 100%) was higher in T1R(+). It is inferred therefore 'viable' bacteria are an essential component in T1R and difference in the quality of bacilli, not the quantity or the ratio of dead to viable play a role in the precipitation of T1R. In conclusion, the findings show that 'metabolically active' M. leprae is a component/prerequisite and the secretory protein Ag 85, might be the trigger for precipitation of T1R.

Type 2 leprosy reaction with Sweet's syndrome-like presentation

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.

Menstrual irregularities, fertility status, and ovarian function in female patients with leprosy in India.

BACKGROUND: Gonadal involvement in males in lepromatous leprosy is not uncommon, but there is a paucity of literature on the involvement of gonads in female patients with leprosy. This study was undertaken to determine if there is any menstrual dysfunction, alteration in fertility status and circulating luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, and estradiol in female patients with paucibacillary (PB) and multibacillary (MB) leprosy. MATERIALS AND METHODS: In a cross-sectional study, 229 patients with leprosy (79 with PB leprosy and 150 with MB leprosy) and 100 age-matched non-leprosy controls were evaluated for menstrual function, fertility status, and circulating sex hormones. RESULTS: Twenty percent of patients with MB leprosy had menstrual irregularities post-dating the onset of leprosy in comparison to 6.3% patients with PB leprosy, and this difference was statistically significant (P < 0.001). However, the fertility profile of patients with PB leprosy was comparable to that of patients with MB leprosy (P > 0.05). A significantly higher number of patients with MB leprosy (9.3%) had elevation of circulating FSH, LH, and prolactin vis-à-vis patients with PB leprosy (1.3%), and this difference was statistically significant (P < 0.05). Similarly, the mean levels of LH, FSH, and prolactin were significantly elevated in patients with MB leprosy vis-à-vis patients with PB leprosy and controls (P < 0.05). CONCLUSIONS: Multibacillary leprosy may be associated with menstrual irregularities and elevation of gonadotropin hormones, indicating an ovarian dysfunction.

Hanseníase históide símile: desafio diagnóstico / Histoid like leprosy: diagnostic challenge

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.

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.

Increased hepcidin expression in multibacillary leprosy

Iron is essential for all organisms and its availability can control the growth of microorganisms; therefore, we examined the role of iron metabolism in multibacillary (MB) leprosy, focusing on the involvement of hepcidin. Erythrograms, iron metabolism parameters, pro-inflammatory cytokines and urinary hepcidin levels were evaluated in patients with MB and matched control subjects. Hepcidin expression in MB lesions was evaluated by quantitative polymerase chain reaction. The expression of ferroportin and hepcidin was evaluated by immunofluorescence in paucibacillary and MB lesions. Analysis of hepcidin protein levels in urine and of hepcidin mRNA and protein levels in leprosy lesions and skin biopsies from healthy control subjects showed elevated hepcidin levels in MB patients. Decreases in haematologic parameters and total iron binding capacity were observed in patients with MB leprosy. Moreover, interleukin-1 beta, ferritin, soluble transferrin receptor and soluble transferrin receptor/log ferritin index values were increased in leprosy patients. Hepcidin was elevated in lepromatous lesions, whereas ferroportin was more abundant in tuberculoid lesions. In addition, hepcidin and ferroportin were not colocalised in the biopsies from leprosy lesions. Anaemia was not commonly observed in patients with MB; however, the observed changes in haematologic parameters indicating altered iron metabolism appeared to result from a mixture of anaemia of inflammation and iron deficiency. Thus, iron sequestration inside host cells might play a role in leprosy by providing an optimal environment for the bacillus.

[Malignant transformation of plantar ulcers in leprosy: experience of National Leprosy Center in Casablanca]. / Dégénérescence carcinomateuse des maux perforants plantaires d'origine lépreuse: expérience du Centre national de léprologie de Casablanca.

Malignant degeneration is a late complication of plantar ulcers in leprosy. The objective of this study is to describe and analyze the epidemiological, clinical, and therapeutic aspects of this complication in Morocco. A retrospective study was conducted from January 2000 to December 2009 at the National Center of Leprosy (CNL) in Casablanca. All our patients had a histological confirmation. Ten patients were included in this study. There were seven men and three women, with a mean age of 58.8 years. Six patients had a multibacillary form of leprosy and four had a paucibacillary form. The average duration of the plantar ulcers was 34.4 years. Clinical appearance at diagnosis was an ulcerative and vegetative tumor. Treatment was by radical amputation. Evolution was marked by metastatic spread in six patients. One patient died of disseminated disease. In Morocco, leprosy has been on the decline since 1990, but the occurrence of late complications in the leprosy patient as carcinoma of plantar ulcers persists. Prevention of these complications should be part of the national fight against leprosy.

Renal involvement in leprosy: report of progression from diffuse proliferative to crescentic glomerulonephritis.

Renal involvement in leprosy has been reported rarely in the literature. Acute kidney injury in patients with leprosy is uncommon and may occur due to acute tubular necrosis, drug-induced interstitial nephritis and rarely crescentic glomerulonephritis. The latter with histologic confirmation of the diagnosis has been reported in very few cases of leprosy. A 25-year-old male, on therapy for multibacillary leprosy, was found to have deranged renal functions on evaluation for a history of nausea, vomiting, swelling and episode of haematuria. Kidney biopsy was performed twice over a period of 2 weeks, showing progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis, pauci-immune in nature. The patient was treated aggressively with intravenous steroids, following which his renal functions stabilized. Crescentic glomerulonephritis, an extremely rare phenomenon in leprosy, should be considered in these patients presenting with features of acute kidney injury. Timely performed renal biopsy assists in accurate diagnosis and appropriate management of the patient, hence preserving renal parenchyma. Rapid progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis in a patient with leprosy is described herein for the first time in the literature.
