Article Synopsis
  • Leprosy is caused by two bacteria, Mycobacterium leprae and Mycobacterium lepromatosis, which can't be easily grown in labs. This study focused on detecting M. lepromatosis in patients with various forms of leprosy, particularly those with type 2 reactions (ENL).
  • The research involved 75 multibacillary leprosy patients and used specific DNA extraction and sequencing techniques to confirm the presence of M. lepromatosis in their samples.
  • Results showed M. lepromatosis in four necrotic ENL patients, with varying levels of genetic similarity to known strains, and specific proteins from the bacteria were identified, supporting its role in leprosy cases studied

Article Synopsis
  • In regions where leprosy is endemic, new cases are still being reported, indicating that the prevalence has not decreased to levels that would qualify as elimination.
  • A study was conducted to assess the viability of Mycobacterium leprae in patients undergoing a 12-month treatment of multidrug therapy, aiming to understand how this affects disease transmission.
  • Out of 78 initial cases, results showed that a significant number retained viable bacteria even after completing the treatment, suggesting that they had active lesions and could still contribute to the spread of the disease.

Objectives: Purulia is one of the high-endemic districts for leprosy in West Bengal (the eastern part of India). The annual new case detection rate (ANCDR) of leprosy in West Bengal is 6.04/100000 (DGHS 2019-20).

Article Synopsis
  • - The text discusses a rare case of erythema multiforme (EM)-like erythema nodosum leprosum (ENL) that appeared unusually after a patient had finished multidrug therapy (MDT) for lepromatous leprosy.
  • - The patient was found to be resistant to rifampicin, a key antibiotic used in leprosy treatment, which raises concerns about treatment effectiveness.
  • - The authors explore the implications of finding antibiotic-resistant bacteria in leprosy patients and how it may lead to unusual reaction presentations like the one described.

The ongoing transmission of leprosy in India is worrisome, and emerging drug resistance may be one of the factors responsible for the continued transmission of leprosy in India. Emerging cases of multidrug-resistant pose a great threat to eradication of leprosy and must be addressed with utmost priority. We report a case of multidrug-resistant in a case of relapse where slit skin smear (SSS) was negative and histopathology was inconclusive.

While Type 1 reaction in Hansen's disease is commonly encountered, the triggers and reasons for its persistence are not well understood even though the immunological milieu and cytokine interplay have been studied. Herein, we present a case of Type 1 downgrading reaction in which multidrug resistance was the probable cause of steroid-nonresponsiveness and which responded promptly on starting alternate antileprosy treatment.

Early diagnosis of leprosy is important for limiting the severity of disease, which may lead to disabilities and deformities if not treated timely. Multiplex PCR employing more than one gene, specific to target DNA, is more efficient detection tool. In the present study, slit skin scrapings, blood, nasal swabs and saliva from Paucibacillary (PB) and Multibacillary (MB) cases as well as household contacts of PB cases were tested by multiplex PCR using three different gene targets namely RLEP, 16SrRNA and sodA.

Background: Leprosy is a chronic infectious disease caused by Mycobacterium leprae and mainly affects skin, peripheral nerves. Vitamin D receptor (VDR) gene polymorphism has been found to be associated with leprosy. Vitamin D has been shown to control several host immunomodulating properties through VDR gene.

Article Synopsis
  • * The study analyzed 380 soil samples and 250 water samples, identifying 86 NTM from soil and 77 NTM from water, revealing both rapid-growing and slow-growing species, including some previously unrecorded in India.
  • * M. leprae, linked to leprosy, was confirmed in the samples and a phylogenetic analysis indicated a close relationship between NTM species and M. leprae, suggesting a potential role of these bacteria in disease development.

Article Synopsis
  • The study focuses on detecting a rare complication of leprosy known as lepromatosis in patients from India, specifically looking for cases of M. lepromatosis.
  • Researchers collected and analyzed 88 skin samples from lepromatous leprosy patients, employing techniques like DNA extraction and PCR to identify potential cases.
  • The findings revealed 4 positive cases of M. lepromatosis, marking the first reported instances in India, indicating the possibility of dual infections with M. leprae in endemic regions.

Despite more than three decades of multidrug therapy (MDT), leprosy remains a major public health issue in several endemic countries, including India. The emergence of drug resistance in is a cause of concern and poses a threat to the leprosy-control program, which might ultimately dampen the achievement of the elimination program of the country. Rifampicin resistance in clinical strains of are supposed to arise from harboring bacterial strains with mutations in the 81-bp rifampicin resistance determining region (RRDR) of the gene.

Article Synopsis
  • * Researchers analyzed samples from relapse and new leprosy cases in India, confirming resistance to key antibiotics (rifampicin, dapsone, and ofloxacin) through genetic mutation analysis.
  • * Results revealed that 15 strains had mutations in at least two resistance genes, indicating a concerning trend of MDR M. leprae in patients previously treated with MDT.
