Unveiling inflammatory biomarkers in multibacillary leprosy: the role of lymphocyte-platelet ratio in predicting leprosy reactions.

Leprosy is a neglected contagious disease that causes physical disability and episodes of inflammation, called leprosy reactions. There are currently no consolidated laboratory markers that can predict or confirm the diagnosis of leprosy reactions, negatively impacting the progression of the disease. The aim of this study was to analyze the behavior of inflammatory biomarkers in a population of patients with multibacillary leprosy. This prospective study in a northeastern capital involved 67 new cases of multibacillary leprosy, assessing inflammatory biomarkers at diagnosis. Histopathology, qPCR, slit skin smear microscopy, and laboratory tests, including CRP-albumin, neutrophil-lymphocyte, lymphocyte-monocyte, platelet-lymphocyte ratios, and systemic immune-inflammation index, were conducted. Statistical analysis utilized Stata version 16.0®, employing Chi-square, Kruskal-Wallis, and Poisson regression (5% significance). The population, mainly young brown men with low socioeconomic status, borderline leprosy, and and degree of physical disability one, saw 19.4% experiencing leprosy reactions. Standard multibacillary multidrug therapy was administered to all. Ratios and index values exceeding medians were prevalent (46.3-47.8%). Assessing biological markers against leprosy reactions revealed a positive relation between reactions and lymphocyte-platelet ratio (p = 0.05) and a positive trend with the systemic immune-inflammation index (p = 0.06). Patients with reactions were 1.3 times more likely to exhibit an elevated lymphocyte-platelet ratio. The lymphocyte-platelet ratio emerged as a potential indicator for recognizing leprosy reactions. Further research is essential to validate these findings, aiming for earlier detection of leprosy reactions.

“Histopthological Spectrum Of Leprosy In A Tertiary Care Centre”

Background: Leprosy affects skin and peripheral nerves, muscles, eyes, bones, testis and internal organs. Histopathology and demonstration of lepra bacilli is a vital role to supplement clinical examination and diagnosis for correct classification and therefore for patients treatment. Aim- To study the Histopathology spectrum of Leprosy in a tertiary care centre. Materials &Methods: All the skin biopsy with clinically suscipious of leprosy and sent for histopathological examination during the year Jan 2020 to Dec 2024 were included in the study. Results: A total of 60 cases were studied out of them 61% are male and 39% are female. With M:F ratio1.56: 1, majority of them belongs to 41-50 age group. The commonest histological type was borderline TB leprosy followed by Borderline lepromatous leprosy, least common cases were of lepromatous leprosy and histoid leprosy. Conclusion: Histopathological examination is the important investigation for accurate diagnosing and typing of leprosy

Clinical and epidemiological panorama of leprosy at a tertiary center across the Nepal–India border in the post-elimination era: A cross-sectional study

ackground: Leprosy, an infectious granulomatous disease caused by Mycobacterium leprae continues to pose a significant public health challenge globally. Despite efforts towards its elimination, leprosy remains a re-emerging threat, with increasing cases in Nepal and India. Understanding the clinical, epidemiological, socioeconomic, and histological profiles of leprosy across the Nepal–India border is essential for effective disease management and control. Methods: A descriptive, prospective study was conducted over three years at a tertiary care center in Nepal. The patients were selected based on predefined inclusion and exclusion criteria. Clinical, epidemiological, and socioeconomic data were collected and analyzed to evaluate the profiles of leprosy cases in the study population. Results: A total of 110 patients were included in the study, with a mean age of 33.54 years. The majority of the patients were Nepalese. The mean duration of the disease was 17.6 months, with a wide range observed. Borderline leprosy was the most common clinical presentation. Bacteriological positivity was observed in 85% of the cases, indicating active transmission of the disease within the community. A significant proportion of the patients (97%) belonged to the low to middle-class category. A reaction was seen in 14.5% of the patients. Conclusion: Despite efforts toward its elimination, leprosy remains a public health problem across borders. The high burden of leprosy cases, coupled with socioeconomic challenges and active transmission, underscores the need for continued vigilance and targeted interventions. Addressing cross-border dynamics, enhancing access to healthcare services, and implementing comprehensive control strategies are essential for effectively controlling leprosy.

Borderline lepromatous leprosy: A case report

Rationale: Lepromatous leprosy can have many atypical presentations, obscuring early diagnosis. We present a case of lepromatous leprosy, presenting with atypical features, which made a diagnostic dilemma. Patient concerns: A 48-year-old man presented with bilateral lower limb oedema and scaly “ichthyosis like” skin rash in both hands and feet, hepatosplenomegaly and pancytopenia, over a course of three months, without any classical features of leprosy. A skin biopsy revealed an unexpected diagnosis of borderline lepromatous leprosy. Diagnosis: Lepromatous leprosy. Interventions: Multi-drug regimen treatment with rifampicin, dapsone and clofazimine for lepromatous leprosy. Outcomes: The patient made a good clinical recovery. Lessons: In endemic settings, clinicians should be aware of similar atypical manifestations of leprosy to face the global challenge of eradicating this chronic deforming disease.

Nail fold capillaroscopy in leprosy: Unveiling the microvascular changes

BackgroundLeprosy, a chronic infectious disease, is associated with various nail changes. Its etiopathogenesis is multifaceted, with microvascular damage being crucial. Nail fold capillaroscopy (NFC) emerges as a novel tool for detecting early vascular deficits in leprosy. The study aimed to assess and provide a complete clinical characterization of NFC changes in leprosy patients. MethodsIt is an observational cross-sectional study, done over a period of 1.5 year (January 2021 to august 2022) in a tertiary care hospital, encompassing 60 patients diagnosed with leprosy (18–60 years). After obtaining informed consent; detailed history, complete cutaneous and neurological examinations were conducted. All fingernails and toenails were examined for clinical changes. Subsequently, onychoscopy was performed using USB type of video-dermatoscope (Model AM7115MZT Dino-lite), a non-invasive tool. This was followed by NFC which was done for all fingernails and images were recorded by single operator, which were then assessed for quantitative and qualitive changes and statistical analysis was conducted using SPSS v20, with mean capillary density compared using Student's t-test, morphological change frequencies assessed by proportions, and group comparisons made using Chi-square or Fischer exact tests, with a significance threshold of p < 0.05. ResultsAmong the 60 patients, 39 were in the lepromatous group, which included both borderline lepromatous (BL) and lepromatous leprosy (LL) patients, and 17 were in the tuberculoid group, which included borderline tuberculoid (BT) leprosy patients; 23.3 % had Type 1 reactions, and 18.3 % had Type 2 reactions. Nail fold capillaroscopy (NFC) showed microvasculature changes in 93.3 % of patients. The average capillary density was 6.8 ± 1.5 capillaries per mm, with the lepromatous group having a lower density (6.5 ± 1.09) compared to the tuberculoid group (7.0 ± 0.86). The most common NFC changes in the tuberculoid group were tortuous capillaries (70 %), capillary dropouts, and dilated capillaries (both 64.7 %). In the lepromatous group, capillary dropouts (82 %) were most frequent, followed by tortuous (69 %), receding (69 %), and dilated capillaries (66 %). A dilated and prominent subpapillary plexus was more common in the lepromatous group (35 %, p = 0.04). Patients with trophic changes in the lepromatous group had more capillary dropouts and bizarre capillaries. Capillary dropouts, dilated capillaries, and visible subpapillary venous plexus were more prevalent in patients with Type 2 reactions. ConclusionNFC changes are prevalent in both tuberculoid and lepromatous leprosy, which may be an indicator of peripheral vascular compromise and trophic changes, especially in lepromatous leprosy. NFC can be an auxiliary tool for detecting microvascular abnormalities in leprosy patients.

Neurological features of Hansen disease: a retrospective, multicenter cohort study

To elucidate the neurological features of Hansen disease. The medical records of patients with confirmed Hansen disease transferred from the neurology department were reviewed, and all medical and neurological manifestations of Hansen disease were assessed. Eleven patients with confirmed Hansen disease, 10 with newly detected Hansen disease and 1 with relapsed Hansen disease, who visited neurology departments were enrolled. The newly detected patients with Hansen disease were classified as having lepromatous leprosy (LL, n = 1), borderline lepromatous leprosy (BL, n = 2), borderline leprosy (BB, n = 2), borderline tuberculoid leprosy (BT, n = 1), tuberculoid leprosy (TT, n = 2), or pure neural leprosy (PNL, n = 2). All of the patients with confirmed Hansen were diagnosed with peripheral neuropathy (100.00%, 11/11). The symptoms and signs presented were mainly limb numbness (100.00%, 11/11), sensory and motor dysfunction (100.00%, 11/11), decreased muscle strength (90.90%, 10/11), and skin lesions (81.81%, 9/11). Nerve morphological features in nerve ultrasonography (US) included peripheral nerve asymmetry and segmental thickening (100.00%, 9/9). For neuro-electrophysiology feature, the frequency of no response of sensory nerves was significantly higher than those of motor nerves [(51.21% 42/82) vs (24.70%, 21/85)(P = 0.0183*)] by electrodiagnostic (EDX) studies. Nerve histological features in nerve biopsy analysis included demyelination (100.00%, 5/5) and axonal damage (60.00%, 3/5). In addition to confirmed diagnoses by acid-fast bacteria (AFB) staining (54.54%, 6/11) and skin pathology analysis (100.00%, 8/8), serology and molecular technology were positive in 36.36% (4/11) and 100.00% (11/11) of confirmed patients of Hansen disease, respectively. It is not uncommon for patients of Hansen disease to visit neurology departments due to peripheral neuropathy. The main pathological features of affected nerves are demyelination and axonal damage. The combination of nerve US, EDX studies, nerve biopsy, and serological and molecular tests can improve the diagnosis of Hansen disease.

Coinfection with Leprosy and Tuberculosis: A Case Series in Malagasy Patients.

Leprosy and tuberculosis are two of the oldest and most common mycobacterial infections, caused by Mycobacterium leprae and Mycobacteium lepramatosis for leprosy and Mycobacterium tuberculosis for tuberculosis. Dual infections have been known since ancient times; however, cases remain rarely reported in the literature, even in countries where both diseases are endemic, such as Madagascar. We report a case series of simultaneous occurrence of leprosy and tuberculosis. In this retrospective study, we reviewed the medical records of patients with leprosy registered at the Department of Dermatology, University Hospital Befelatanana, Antananarivo, Madagascar, between January 2012 and June 2021. Patients with leprosy and diagnosed as coinfected by tuberculosis were included in the study. Of the 120 leprosy cases observed during the study period, coinfection with leprosy and tuberculosis was found in five patients. The mean age was 43.4 (SD 13.2) ranging, 21-59 years. Male gender was predominant (4/5). Four patients presented with lepromatous leprosy, and one with borderline lepromatous leprosy. Three patients experienced leprosy reaction. Four cases of pulmonary tuberculosis and one case of multifocal tuberculosis were observed. The diagnosis of leprosy preceded tuberculosis in four cases, and a coinfection diagnosis was made simultaneously in one case. The average time to develop tuberculosis was 38.8 (SD 10.2) months. HIV infection, malnutrition, alcohol consumption, and long-term corticosteroid therapy were the immunosuppressive factors reported in our patients. Three patients received concomitant multidrug therapy for leprosy and tuberculosis. Dermatologists should be aware of the importance of screening patients affected by leprosy for latent or active tuberculosis to prevent morbidity and mortality due to coinfection and to reduce the risk of acquired resistance to rifampicin, which is the greatest risk of this association.

Leprosy- Atypical Presentation with Reaction

Leprosy is a chronic granulomatous disease affecting mainly the skin and nerves caused by the obligate intracellular pathogen Mycobacterium leprae. Patient not always present with typical skin lesion with loss of sensation or muscle weakness rather may present with atypical skin lesion with swelling of the affected area like cellulites or lymphangitis as reactional state. A 25- years-old male patient presented with linear erythematous verrucous plaque along with multiple nodules and pain and swelling of left upper extremity. Local examination revealed sensory loss on inner aspect of left hand and finger and ulner nerve found enlarged, thickened and tender. Slit skin smear showed numerous lepra bacilli. Skin biopsy for histopathology showed collection of foamy histocytes forming granuloma within the upper dermis and wade fite staining, moderate number of lepra bacilli was seen. Patient was diagnosed as a case of borderline leprosy with type 1 lepra reaction. Patient was getting treatment with MDT (multi drug therapy) and systemic steroid and responded very well. His skin lesions are almost subsided and weakness of hand was recovering gradually. JAFMC Bangladesh. Vol 19, No 1 (June) 2023: 76-79

Neutrophilic leukocytosis and erythema nodosum leprosum in leprosy: insights from a retrospective observational study.

Leprosy reactions represent immunologically mediated episodes of acute inflammation that, if not diagnosed and treated promptly, can cause irreversible impairment of nerve function and permanent disabilities. A frequent type of reaction experienced by patients with lepromatous leprosy (LL) and borderline lepromatous leprosy (BL) is erythema nodosum leprosum (ENL), an inflammatory complication that may become chronic or recur in multiple episodes. Although ENL is commonly described as a neutrophil-mediated immune disease, the role of neutrophils is not fully understood. In this study, we assess neutrophilic leukocytosis in a retrospective cohort of patients affected by BL or LL leprosy. A retrospective observational study was performed using data from 146 patients with BL and LL leprosy diagnosed and treated at the Souza Araújo Outpatient Clinic, Fiocruz, Rio de Janeiro, Brazil. Clinical, demographic, and hematological data were extracted from medical records. Skin biopsy samples obtained from patients for ENL diagnosis were used for histopathological evaluations. Most patients were male (75%) and had a reactional episode (85%), of which 65% were ENL. Multiple episodes were common, 55% of the 80 patients with ENL presented more than 2 episodes (average of 2.6 episodes). In treatment-naive BL/LL patients, the median blood neutrophil counts of patients who developed ENL at some points of their disease course were higher than those who did not experience any reaction (median= 4,567 cells/mm3 vs 3,731 cells/mm3 respectively, p=0.0286). A correlation between the increase in median neutrophil counts and ENL severity was confirmed (6,066 cells/mm3 for mild ENL vs 10,243 cells/mm3 for moderate/severe ENL, p=0.0009). A longitudinal assessment was also performed in 34 patients, confirming the neutrophilic leukocytosis (BL/LL: 4896 cells/mm3 vs ENL: 8408 cells/mm3, p<0.0001). Moreover, increased NLR was associated with a greater neutrophilic infiltration in ENL lesions. We demonstrate that ENL episodes in patients affected by leprosy are associated with elevated blood leukocyte and neutrophil counts and an increased NLR. These findings highlight the significant involvement of neutrophils in the ENL immunological/inflammatory process.

Diagnosis and Treatment of Leprosy in Taiwan during the COVID-19 Pandemic: A Retrospective Study in a Tertiaty Center.

Currently, over 200,000 new cases of leprosy are reported annually worldwide. Although leprosy was thought to have been eradicated in Taiwan, a few new cases still occur annually. Protean clinical manifestations of leprosy and immunological reactions result in delayed diagnoses. In addition, drug-resistant leprosy is emerging and poses treatment challenges. In this retrospective study, we collected and analyzed the clinicopathological features, leprosy type, treatment response, and relapse rate of patients with leprosy in our hospital between January 2009 and November 2022. We found that 54% of patients were Indonesian, and borderline lepromatous leprosy was predominant (39%); moreover, histoid leprosy and the Lucio phenomenon were also reported. Polymerase chain reaction analysis identified four positive cases, including a dapsone-resistant (4%) case. Our findings indicated good control of leprosy and a lower rate of dapsone resistance than that reported by the World Health Organization (4% vs. 13%) from 2009 to 2015. We found that the patient profile in terms of the treatment duration, recurrence rate, systemic symptoms, and neurological symptoms did not differ between before and during the pandemic. We report the recent advances in leprosy diagnosis, drug-resistant gene mutations, post-exposure prophylaxis, vaccination, and the effect of coronavirus disease 2019 on leprosy to facilitate updated leprosy diagnosis and management.

Genomic characterization of Mycobacterium lepromatosis from ENL patients from India

BackgroundLeprosy is caused by Mycobacterium leprae and Mycobacterium lepromatosis. Both organisms cannot be cultured in vitro. M. lepromatosis was found to be associated mainly with diffuse lepromatous leprosy and with Lucio's phenomena initially. Later, M. lepromatosis was observed in borderline leprosy cases (BL), lepromatous leprosy cases (LL) and leprosy reactional cases (T1R and ENL). Although many cases are being reported with similar clinical features like Lucio phenomenon in India but M. lepromatosis was not isolated from these cases. The aim of this study was to screen MB patients and patients with type 2 reaction for the presence of M. lepromatosis. MethodologyWe recruited a total of 75 multibacillary leprosy cases (45 MB cases without reaction and 30 type 2 reaction (ENL) cases) from TLM hospitals Purulia (West Bengal), Barabanki (Uttar Pradesh), Shahdara (Delhi) and PGIMER (Chandigarh), India. Punch biopsies of 5 mm were collected in 70% ethanol from all the study subjects. DNA was extracted followed by Hemi-nested PCR targeting 16S rRNA gene specific for M. lepromatosis. Further, PCR products were processed for Sanger sequencing for an absolute confirmation of M. lepromatosis. Whole genome sequencing was done to confirm the presence of M. lepromatosis. ResultWe observed presence of M. lepromatosis in 4 necrotic ENL patients by heminested PCR. There was 100% 16S rRNA sequence similarity with M. lepromatosis FJ924 in one case, 98.96% in two cases and in one case it was 90.9% similarity by nucleotide BLAST (BLASTn) by using the NCBI website. On the basis of Sanger sequencing, we noted presence of M. lepromatosis in 3 necrotic ENL patients as one sample only gave 90.9% similarity by BLASTn. On the basis of de novo assembly and genome obtained, only one sample S4 with a 2.9 mb genome size was qualified for downstream analysis. Sixteen M. lepromatosis- specific proteins were identified in this case and the closest species was M. lepromatosis strain FJ924 based on whole genome level phylogeny. ConclusionThese results provide valuable insights into the prevalence of M. lepromatosis in ENL patients in different regions of India and contribute to our understanding of the genetic characteristics of this pathogen in the context of leprosy.

Assessment of Clinical, Histopathological, and Bacteriological Findings in Treated Leprosy Patients with Persistent Skin Lesions: A Retrospective Cohort Study.

Since the introduction of multidrug therapy (MDT), various disabilities/morbidities due to leprosy have been prevented. However, there is a subset of patients in whom the skin lesions do not resolve completely or remain unchanged despite a full course of MDT, which is a great source of anxiety to the patient and their family members. Hence, we tried to ascertain the putative causes and risk factors of persistent skin lesions (PSLs) by analyzing the clinical, histopathological, bacteriological, and drug resistance patterns. This is a retrospective, cohort study wherein 35 patients who had PSLs after completion of MDT were included. The majority of the patients were 18 to 30 years of age, with males predominating. Borderline tuberculoid leprosy was the most common clinical spectrum observed (71.4%). The majority had PSLs distributed predominantly over photo-exposed sites (upper limbs > trunk > face). Eight patients (22.8%) had a history of contact with leprosy patients in their family, and six patients (17.1%) had associated comorbidities. Improvement in histopathological parameters such as a decrease in granuloma fraction was observed in 22 patients (62.8%) with PSLs after release from treatment in comparison with baseline. Four patients (11.4%) were noted to have drug resistance (three to rifampicin and one to dapsone). Thus, our study emphasizes that leprosy patients with PSLs after completion of MDT should undergo histopathological evaluation and drug resistance studies.

Clinico-Epidemiological Trends of Leprosy at a Tertiary Care Centre of South Rajasthan: A 10-Year Retrospective Study.

Leprosy is a major public health problem in India, which affects many people every year and has significantly high new case detection rates in certain districts and blocks. According to the National Leprosy Elimination Program (NLEP) report of March 2019, there were a total of 1.14 lakhs new cases of leprosy in India with an Annual New Case Detection Rate (ANCDR) of 8.1 per 100,000 population. The present study aimed at determining the epidemiological and clinical profile of leprosy patients from a tertiary level teaching hospital in South Rajasthan. A retrospective, record-based study was carried out on patients registered in the leprosy clinic of a tertiary level teaching hospital of South Rajasthan during a period of ten years (2010-2019). Data regarding the demographic profile, clinical features, treatment given, and complications were analysed. A total of 1372 patients registered in the leprosy clinic during a period of 10 years were evaluated. There were 1007 (73.4%) males and 365 (26.6%) females with a male-female ratio of 2.76:1. The majority of patients 671 (48.9%) belonged to the middle age group (21-40 years). Multibacillary leprosy was the most common clinical type seen in 1109 patients (80.8%). Borderline leprosy was the most common morphological type, determined in 625 (45.6%) patients, of which BL (21.0%) was the most common group. 16.7% patients presented with leprosy reaction at the time of initial diagnosis. Type 1 reaction was seen in 91(6.6%) and type 2 reaction in 138 (10.1%) patients. Grade I disability was observed in 347 (25.3%) patients whereas grade II disability was seen in 456 (33.2%) patients. 54 patients (3.9%) had a definite history of contact in the family. 28 patients defaulted during the study period. Yearly trend of epidemiological and operational parameters was observed, and the parameters were compared with the national data. Persistent high proportion of multibacillary cases and grade 2 disability indicates that leprosy continues to be a significant health care problem despite statistical elimination. There is a clear need to strengthen early detection, treatment and regular follow-up of these cases in both high and low endemic settings.

Clinicoepidemiologic profile of leprosy in geriatric population in post-elimination era: A retrospective, hospital-based, cross-sectional study from Eastern India.

Geriatric populations are susceptible to leprosy infection with masked clinical signs due to lower immunity in them. Our aim was to analyze the clinicoepidemiologic profile of patients with geriatric leprosy and find out the reasons for delayed diagnosis and treatment. A retrospective, record-based study was conducted in a tertiary care center from May 2019 to May 2022. The clinicodemographic data of biopsy-confirmed leprosy cases aged ≥60 years were obtained from the leprosy clinic record. Various reasons for the delay in treatment were also recorded. Simple statistics was used for analysis. Out of 605 leprosy cases, 50 (7.4%) cases belonged to the geriatric population. Males outnumbered females (M/F = 37/13). The mean age of the patients was 66.28 + 6.5 years. Maximum patients belonged to 60-69 years of age. The mean duration of illness was 35.22 months (range 1-240 months). Most of the patients were illiterate (33.6%), and 56% were farmers by occupation. The ulnar nerve was the most common nerve to be thickened in 90% (45/50) cases, followed by the common peroneal nerve in 54% (27/50) cases, radical cutaneous nerve in 52% (26/50) cases, and posterior tibial nerve in 24% (12/50) cases. Borderline tuberculoid was the most common type in 44% cases, followed by lepromatous leprosy in 22%, borderline lepromatous leprosy in 18% (9/50), and pure neuritic leprosy in 14%. Type 1 and type 2 lepra reactions were found in 18% and 14% cases, respectively. Also, 38% had grade 2 disability. Common reasons for the delay in treatment were financial constraints, lack of family support, and personal superstitious beliefs. The study was limited by its retrospective nature. Geriatric leprosy needs special attention as the elderly are more prone for deformities; also, because of low immunity, there is a high chance of developing multibacillary leprosy, and therefore, they are potential sources of infection to the community.

Our Experience on Unusual Manifestations of Hansen’s Disease - A Case Series

Abstract Hansen’s disease is caused by an acid–fast bacillus – Mycobacterium leprae. Diagnosis of Hansen’s disease is mainly clinical. Hence, it is crucial to be aware of its diverse manifestations. We hereby report three such cases of Hansen’s disease with uncommon presentation. Case 1: A 26-year-old male presented with progressive numbness and multiple skin lesions over both upper and lower limbs in the past 3 years. Case 2: A 26-year-old male presented with tingling sensation of both upper limbs and lower limbs along with multiple skin lesions all over the body in the past 10 months. Case 3: A 39-year-old male presented with multiple joint pain, electric shock-like sensation of both upper limbs, and weakness of both hands along with skin rashes all over the body in the past 1 month. Skin examination of all these patients revealed multiple hypoanesthetic erythematous patches in the involved areas. Nerve conduction study was suggestive of asymmetric sensory motor axonal polyneuropathy. Skin biopsy from the lesions of the first patient revealed epithelioid granulomas suggesting borderline tuberculoid leprosy. Ziehl–Neelsen stain was positive for both fragmented and intact bacilli in the second and third cases, suggesting lepromatous leprosy. All of them were treated successfully with antileprosy drugs. It is essential to consider leprosy as a differential diagnosis in all patients presenting with symptoms of peripheral neuropathy, so that an early diagnosis and treatment is possible.

Borderline type leprosy with variation of clinical manifestations and histopathology: two case reports

Link of Video Abstract: https://youtu.be/HgIJyHrxoOc Background: Leprosy is a chronic disease caused by Mycobacterium leprae. This disease can be diagnosed if one of the four criteria is met. Histopathological examination can vary depending on the spectrum of the disease. The following describes two cases of borderline-type leprosy that aimed to increase understanding of the diagnosis and management of leprosy, especially the borderline type. Cases: Both cases had complaints of numb spots on the body. The first case had more lesions than the second one with borderline-borderline histopathological examination results, while the second one had borderline lepromatous histopathological examination results. Both patients received the same therapy (multidrug therapy for multibacillary leprosy). During observation, there were no drug side effects that the patient could not tolerate. The prognosis in both cases is dubia, depending on the patient's adherence to treatment. Conclusion: The diversity of clinical and histopathological features can occur, including cases of leprosy. Early diagnosis and prompt treatment should be started as possible to prevent disabilities.

A RETROSPECTIVE STUDY OF HISTOMORPHOLOGICAL SPECTRUM OF HANSEN’S DISEASE IN A TERTIARY CARE CENTRE OF BARABANKI AREA

Objectives: Hansen’s disease is a chronic granulomatous infectious disease caused by Mycobacterium leprae. Early detection is essential to prevent the disease’s spread and disability. Due to the multitude of morphologies, it may be difficult to accurately diagnose certain cases based solely on clinical signs; therefore, histopathology is crucial for definitive diagnosis. The study aims to investigate the various histological forms of leprosy over a year in a tertiary care hospital. Methods: It was a retrospective study that included 25 leprosy cases that were clinically and histopathologically diagnosed from July 2021 to August 2022 in a tertiary care center. Results: The majority of the cases were from the second decade with the male predominance of the cases (M:F=1.5:1). According to histomorphology, tuberculoid leprosy was the most common type (36%), followed by borderline tuberculoid (24%), borderline lepromatous (16%), lepromatous leprosy (8%), borderline leprosy (8%), histoid leprosy (4%), and indeterminate leprosy (4%). Ziehl–Neelsen staining for acid-fast bacilli demonstrated positivity in 8 cases. Conclusion: As the clinical spectrum of leprosy is diverse, histopathology is the gold standard for the diagnosis and a key tool in obtaining a conclusive diagnosis.

Histoid leprosy complicated by erythema nodosum leprosum mimicking connective tissue disease.

Erythema nodosum leprosum (ENL) is an immunological complication of leprosy seen in 50% of lepromatous and 10% of borderline lepromatous leprosy. It usually presents as a multisystem disease with papulo-nodular skin lesions and fever. Arthralgia or arthritis is a common initial presentation of erythema nodosum leprosum. Pure rheumatologic presentation of lepromatous leprosy complicated by erythema nodosum leprosum is extremely rare, mimics connective tissue disease and is treated with steroids.
