Structure-Guided Computational Approaches to Unravel Druggable Proteomic Landscape of .

Front Mol Biosci 2021 7;8:663301. Epub 2021 May 7.

Department of Biochemistry, University of Cambridge, Cambridge, United Kingdom.

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.

Sonographic pattern of median nerve enlargement in Hansen's neuropathy.

Acta Neurol Scand 2021 Apr 26. Epub 2021 Apr 26.

Karnataka Medical Research Foundation, Bangalore, India.

Objectives: Median nerve enlargement in leprosy seems to be more proximal than in carpal tunnel syndrome (CTS), but this feature has not been studied systematically. The aim of the study was to compare the sites of median nerve enlargement in patients with leprosy with that of patients with CTS.

Materials And Methods: Transverse sections of the median nerve were recorded from wrist to the mid-forearm (at distal wrist crease and at 2-cm: M1, 4-cm: M2, 6-cm: M3, 8-cm: M4 and 10-cm: M5, proximal to the distal wrist crease in the forearm) in patients with leprosy, CTS and healthy subjects using high-resolution ultrasound.

Death and Rebirth of the Thalidomide Molecule: A Case of Thalidomide-Induced Sensory Neuropathy.

Cureus 2021 Feb 4;13(2):e13140. Epub 2021 Feb 4.

Neurology, Flowers Medical Group, Dothan, USA.

The thalidomide molecule is a remarkable molecule that exists in a racemic mixture of optical isomers. In the 1950s, due to its teratogenicity, the levorotatory isomer led to its dramatic downfall. However, the molecule with its panoramic mechanisms of action and its uncanny ability to intercalate within the geometry of deoxyribonucleic acid (DNA), led to its remarkable renaissance; thalidomide being United States Food and Drug Administration (FDA)-approved for at least 13 different indications ranging from multiple myeloma to leprosy to glioblastoma.

Relationship between Plantar Pressure and Sensory Disturbance in Patients with Hansen's Disease-Preliminary Research and Review of the Literature.

Sensors (Basel) 2020 Dec 6;20(23). Epub 2020 Dec 6.

Department of Dermatology, National Sanatorium Tamazenshoen, Higashi-Murayama, Tokyo 189-0002, Japan.

Orthoses and insoles are among the primary treatments and prevention methods of refractory plantar ulcers in patients with Hansen's disease. While dynamic plantar pressure and tactile sensory disturbance are the critical pathological factors, few studies have investigated whether a relationship exists between these two factors. In this study, dynamic pressure measured using F-scan system and tactile sensory threshold evaluated with monofilament testing were determined for 12 areas of 20 feet in patients with chronic Hansen's disease.

Functional Impairment of Skin Appendages Due to Peripheral Nerve Involvement by .

Open Forum Infect Dis 2020 Oct 12;7(10):ofaa419. Epub 2020 Sep 12.

Leprology-Venereology Service, Muhimbili National Hospital, Dar es Salaam, United Republic of Tanzania.

In the earliest stage of infection, bacteria parasitize fine fiber twigs of autonomic peripheral nerves supplying efferent impulses to appendages of the skin. This obligate intracellular pathogen invades Schwann cells, the glial cells of peripheral nerves. Intracellular events inhibit Schwann cell physiology in complex ways, which include demyelination and dedifferentiation. Read More

Department of Infectious, Tropical Diseases and Microbiology, I.R.C.C.S. Sacro Cuore Don Calabria Hospital, Via Sempreboni 5, 37024 Negrar di Valpolicella, Italy.

Leprosy is a chronic neglected infectious disease that affects over 200,000 people each year and causes disabilities in more than four million people in Asia, Africa, and Latin America. The disease can appear with a wide spectrum of clinical forms, and therefore the clinical suspicion is often difficult. Refugees and migrants from endemic countries affected by leprosy can remain undiagnosed in Europe due to the unpreparedness of clinicians. Read More

Peripheral nerve biopsy: a tool still needed in the early diagnosis of neural leprosy?

Trans R Soc Trop Med Hyg 2020 11;114(11):792-797

National Reference Center for Sanitary Dermatology and Leprosy, School of Medicine, Federal University of Uberlândia (UFU), 1720 Pará Avenue, Uberlândia, MG, 38400-902, Brazil.

Background: The early recognition of neural impairment in leprosy, especially in primary neural forms, represents a challenge in clinical practice and a peripheral nerve biopsy may be required for diagnostic confirmation. This study aims to characterize the epidemiological, clinical, electroneuromyographic, laboratory and histopathological aspects of patients undergoing peripheral nerve biopsy during investigation of primary neural cases in leprosy.
