Leprosy is a neglected tropical disease (NTD) that continues to burden low- and middle-income countries (LMICs), despite being eliminated as a public health concern by the World Health Organization (WHO) in 2000. The causative agents, and , affect nearly 200,000 individuals globally each year, with over 19,000 new cases detected in the Americas in 2020 alone. Canada has experienced an increasing incidence of leprosy, due to rising levels of travel and migration from endemic areas, reaching over 37,000 individuals with leprosy by the end of 2020.

Department of Internal Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, BGD.

In Bangladesh, tuberculosis and leprosy are endemic mycobacterial diseases; however, co-infection is rarely seen. Our patient had a high-grade fever, symmetrical polyarthritis, polymorphous erythematous lesions, widespread lymphadenopathy, peripheral neuropathy, bilaterally thickened ulnar nerves, and claw hands. A lymph node biopsy revealed tuberculosis having acid-fast bacilli with caseating epithelioid histiocytic granuloma. Read More

Laboratory of Cell Biology, Institute of Biological Sciences, Federal University of Juiz de Fora, Juiz de Fora, Brazil.

Peripheral neuropathy is the main cause of physical disability in leprosy patients. Importantly, the extension and pattern of peripheral damage has been linked to how the host cell will respond against () infection, in particular, how the pathogen will establish infection in Schwann cells. Interestingly, viable and dead have been linked to neuropathology of leprosy by distinct mechanisms. Read More

Kynurenines in the Pathogenesis of Peripheral Neuropathy During Leprosy and COVID-19.

Front Cell Infect Microbiol 2022 24;12:815738. Epub 2022 Feb 24.

Leprosy Laboratory, Oswaldo Cruz Institute, Oswaldo Cruz Foundation, Rio de Janeiro, Brazil.

Inflammatory disorders are associated with the activation of tryptophan (TRYP) catabolism the kynurenine pathway (KP). Several reports have demonstrated the role of KP in the immunopathophysiology of both leprosy and coronavirus disease 19 (COVID-19). The nervous system can be affected in infections caused by both and SARS-CoV-2, but the mechanisms involved in the peripheral neural damage induced by these infectious agents are not fully understood.

The red flags of ulnar neuropathy in leprosy.

PLoS One 2021 19;16(11):e0259804. Epub 2021 Nov 19.

Oswaldo Cruz Institute, Fiocruz, Rio de Janeiro, Brazil.

The diagnosis of pure neural leprosy is more challenging because patients share characteristics with other common pathologies, such as ulnar compression, which should be taken into consideration for differential diagnosis. In this study, we identify ulnar nerve conduction characteristics to aid in the differential diagnosis of ulnar neuropathy (UN) in leprosy and that of non-leprosy etiology. In addition, we include putative markers to better understand the inflammatory process that may occur in the nerve. Read More

Division of Neuromuscular Disorders, Department of Neurology, Ribeirão Preto School of Medicine, University of São Paulo, Ribeirão Preto 14048-900, Brazil.

Disability in leprosy is a direct consequence of damage to the peripheral nervous system which is usually worse in patients with no skin manifestations, an underdiagnosed subtype of leprosy known as primary neural leprosy. We evaluated clinical, neurophysiological and laboratory findings of 164 patients with definite and probable primary neural leprosy diagnoses. To better understand the disease progression and to improve primary neural leprosy clinical recognition we compared the characteristics of patients with short (≤12 months) and long (>12 months) disease duration.

Clinical prediction rules for the diagnosis of neuritis in leprosy.

BMC Infect Dis 2021 Aug 23;21(1):858. Epub 2021 Aug 23.

Leprosy Laboratory, Oswaldo Cruz Institute, Fiocruz, Av. Brasil, 4365, Manguinhos, Rio de Janeiro, RJ, 21240-360, Brazil.

Background: Diagnosing neuritis in leprosy patients with neuropathic pain or chronic neuropathy remains challenging since no specific laboratory or neurophysiological marker is available.

Methods: In a cross-sectional study developed at a leprosy outpatient clinic in Rio de Janeiro, RJ, Brazil, 54 individuals complaining of neural pain (single or multiple sites) were classified into two groups ("neuropathic pain" or "neuritis") by a neurological specialist in leprosy based on anamnesis together with clinical and electrophysiological examinations.

Leprosy, caused by , is treated with a multidrug regimen comprising Dapsone, Rifampicin, and Clofazimine. These drugs exhibit bacteriostatic, bactericidal and anti-inflammatory properties, respectively, and control the dissemination of infection in the host. However, the current treatment is not cost-effective, does not favor patient compliance due to its long duration (12 months) and does not protect against the incumbent nerve damage, which is a severe leprosy complication.
