Leprosy, Multibacillary*

Introduction: Hansen’s disease (HD) is a chronic granulomatous disease principally affecting the skin and peripheral nervous system caused by Mycobacterium leprae. The incubation period varies from months to more than 30 years. The tuberculoid form of HD usually presents with a single hypoesthetic patch and skin biopsy shows epithelioid granulomas with absence of bacilli on Fite-Faraco stain. In contradistinction, lepromatous leprosy usually presents with numerous papules, plaques and nodules with induration of the ears and nose. Biopsy shows foamy granulomas with presence of acid-fast bacilli on Fite-Faraco stain. Case summary: We present a case of a 13-year old female who presented with a 3-year history of a single hypoesthetic patch on the left knee. The initial clinical diagnosis was tuberculoid leprosy. However, histopathology revealed a Grenz zone, and a nodular granulomatous infiltrate consisting of epitheloid and foamy histiocytes with scattered lymphocytes. Fite-Faraco stain showed a bacillary index (BI) of 3+. Slit-skin smear revealed a BI of 4+. She was then started on multidrug therapy. Conclusion This case highlights the importance of slit-skin smear and biopsy as routine procedures in all new cases of suspected HD. These procedures will help differentiate multibacillary from paucibacillary forms of the disease which will influence decisions for treatment and prognostication. This case emphasizes that lepromatous leprosy may present with single lesions and may be misdiagnosed as paucibacillary leprosy if skin-slit smear and biopsy have not been done. This case further suggests that there are factors yet undetermined which play significant roles in determining the host response to M. leprae which are believed to influence morphology, configuration, number and distribution of skin lesions.

INTRODUCTION: This paper documents the variations in the diagnosis and management of multibacillary leprosy patients in three of the biggest case-holding hospitals in Metro Manila. Furthermore, we aimed to discuss the implications of these variations on the country's leprosy control and elimination program.

METHODS: Focus group discussions (FGD) were conducted with 23 health professionals composed of doctors and nurses with at least a year of experience in managing leprosy patients. The topics included procedures on patient diagnosis and management such as treatment duration, patient follow-up and definitions of treatment completion and default. The FGD participants provided suggestions to improve treatment compliance of patients. Their responses were compared with the World Health Organization (WHO) standards and/or the 2002 DOH Manual of Operating Procedures (MOP) for leprosy. Transcripts of the recordings of the FGDs were prepared and thematic analysis was then performed.

RESULTS: There were variations in the hospitals' procedures to diagnose leprosy, in treatment duration, and in patient follow-up. Definitions for treatment completion and default differed not just between hospitals but also with the WHO guidelines and the 2002 MOP. Hospitals extended treatment up to 24 or even 36 months, despite the 12 months stipulated in the MOP. Two hospitals required a slit skin smear and skin biopsy in diagnosis, despite the MOP and WHO provisions that these were not mandatory. One hospital defined default as three consecutive months without treatment, which was different from the MOP and WHO standards and from the other hospitals.

CONCLUSION: Given the variations in patient management, we recommended that the effectiveness of the standard treatment relative to other regimens being practiced by specialists be evaluated.

INTRODUCTION: Along with the remarkable decrease in incidence of Hansen's disease, many physicians have little experience and are unfamiliar with the disease entity. Consequently physicians may make an error in or delay the correct diagnosis more frequently in these days. We feel that the physicians should constantly be interested in Hansen's disease, and be aware of the updated aspects as compared with the past. MATERIAL AND METHODS: We have analysed 13 new patients of Hansen's disease in Busan, Ulsan, and Kyungnam district during last 6 years (2002-2007). The clinical features of 13 new patients were compared with 370 cases reported 30 years ago, in our clinic. RESULTS: Among 13 patients, male was 4 and female was 9. Mean age was 63 years, and the mean duration until diagnosis was 15.6 months. Two patients had familial history of Hansen's disease. In the classification, lepromatous leprosy was 6, borderline lepromatous leproys was 4, mid-borderline leprosy was 1, borderline tuberculoid leprosy was 1, and tuberculoid leprosy was 1. Eight patients of 13 have experienced lepra reaction. Level of BI and PGL-I antibody corresponded with type of the disease. Among 13 patients, 9 patients (69.2%) were resident in Busan. CONCLUSION: There was an increase in female population, and mutibacillary forms of Hansen's disease were more common as compared with the past. Since majority of patients were resident in Busan and the duration until diagnosis was too long, the dermatologist, especially in Busan should be interested in and carry on clinical studies of Hansen's disease constantly.

The rate of the relapse of leprosy differs from researcher to researcher, so it is thought that the exact decision on the termination of a treatment would play an important role in lowering the rate of the relapse of leprosy. This study attempts to lower the rate of the relapse of leprosy by the decision for termination of leprosy treatment by using reticulum stain of skin in leprosy which is one of granulomatous diseases, as granuloma can be easily observed in reticulum stain in sarcoidosis which is one of the common granulomatous diseases. The patients for this study consisted of five cases of lepromatous type leprosy, three cases of tuberculoid type leprosy, and one case of borderline tuberculoid leprosy. They were treated by a multidrug therapy, and its clinical lesions were observed every month. Also skin biopsy was performed every six months, and the changes of granuloma and acid-fast bacilli were observed in accordance with hematoxylin-eosin, Fite-Farraco, and reticulum stain which provides a better observation of granuloma lesion. Skin lesion of paucibacillary leprosy disappeared in 8 to 12 months, but seen from skin biopsy, epitheloid cell granuloma began to disappear after several months and after 12 months, it almost disappeared. But in some lesion, it remained until 21 months, and even after 33 months, perivascular inflammatory cell infiltrations were found. Skin lesions of multibacillary leprosy disappeared within 9 to 33 months, and bacilli checked by skin smear turned negative, but according to a skin biopsy, the number or the size of the foamy histiocytic granuloma became smaller. There was an example that it still remained after 84-month treatment. As a rule, reticulum stain in leprosy made reticulum fibers surround granuloma in various ways, so it helped us to observe distinctively granuloma. In a treatment of leprosy, it could prevent the relapse of leprosy that the already treated lesions should be checked with repeated skin biopsies at certain intervals, though skin lesions disappear and bacilli are not found in a skin smear. It is concluded that reticulum stain could be one of the useful methods in observing granulomatous lesions for determination of healing of leprosy.

A 36 year-old woman immigrated from Nepal showed erythematous plaques on her face, buttock and legs one month after the immigration. Before the correct diagnosis was made, the patient had been erroneously treated as anallergic dermatitis for three months. Clinico-pathologically, her skin lesion was borderline lepromatous type leprosy with bacilli positive. We report the case to keep the high index of suspicion for leprosy when we meet with patients from the countries where leprosy is still epidemic.

The Ziehl-Neelson's AFB staining method was mainly used for the AFB observation of the mycobacteria. However, this method has several issues of false negative results, and hence a comparative experiment of the Ziehl-Neelson's AFB staining and the fluorescence staining method was done to remedy this problem. As the fluorescence staining method brightly highlights the AFB in a dark field, and also as it is observed with the lower power objective, it is a method that can better the observation and shorten the time of observation as well. The fluorescence staining method that was used in this experiment did a comparative analysis of the Auramine O-Rhodamine B and the Acridine Orange. The results showed that although the Auramine O-Rhodamine B allows easier observation of the AFB with a high fluorescence expression rate for the multibacillary leprosy sample, the darkness on the periphery makes it hard to observe anything else, while also making it hard to observe the cell changes and paucibacillary leprosy of the AFB. However, the Acridine Orange staining method highlights the cells in dark green and changes the color of the AFB from bright red to orange making it easier to observe bacilli. The results of the study show that the Acridine Orange method is superior to the Auramine O-Rhodamine B method in detecting acid fast bacilli in specimen.

Immunohistochemical staining was performed in 20 skin granulomas of 16 patients with leprosy using antisera against lysozyme and S-100 protein. In lepromatous leprosy, lysozyme positive cells and S-100 protein positive cells were rarely found in the dermis. However, the histoid leprosy specimen had large numbers of lysozyrne positive cells and S-100 protein positive cells in granuloma. In borderline group, lysozyme positive cells and S-l00 protein positive cells were found in the dermis. S-100 protein positive cells were diffusely distributed throughuut the granuloma in borderline lepromatous leprosy, while they were often found in lymphocytic mantle in borderline tuberculoid leprosy. In tuberculoid leprosy, lysozymal staining was encouritered in epitheloid cells and giant cells, but S-100 protein positive cells were predominantly found encircling granuloma. In the epidermis, great numbers of S-l00 protein positive cells were found in tuberculoid leprosy than in lepromatous leprosy.

Leprosy is a chronic granulomatous disease affecting the skin and peripheral nervous system. Because of its variable manifestations, leprosy can be misdiagnosed as syphilis, sarcoidosis, psoriasis and eczema. A 73 year-old man showed erythematous papules on his arms and legs. He had been erroneously treated as eczema before the correct clinicopathological diagnosis of borderline lepromatous leprosy was made. We report this case to suggest that dermatologists should pay careful attention while diagnosing new cases of leprosy.

Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae, which primarily affects the skin and peripheral nerves. In this article, we present a 45-year-old man and a 39-year-old women who suffered from asymptomatic irregular erythemas on their trunk and extremities. Since both patients denied the history of exposure to leprosy patients and were absent clinical signs of superficial sensation dysfunction and enlarged peripheral nerves, they were diagnosed of mycosis fungoides and livedo reticularis clinically. Nevertheless the biopsies of erythemas showed perineural and periadnexal foamy-cell granulomas in the dermis and Fite staining revealed a large number of acid-fast bacilli. A diagnosis of multibacillary leprosy was made finally. These cases revealed that since leprosy is still epidemic in some remote area in China and in other developing countries and its clinical manifestations may be very weird sometimes, the dermatologists should be alert of it and skin biopsy could confirm the diagnosis.
