Leprosy in skulls from the Paris Catacombs.

Conclusions: The proportion of skulls with probable signs of leprosy gives an approximate estimate (0.5%) for the prevalence of this disease in the population of Paris (or districts of Paris) during the 15-18th centuries. PMID: 31989850 [PubMed - as supplied by publisher]

Conclusions/SignificanceDespite their high impact on affected populations, we observed a high level of ignorance and neglect toward common skin diseases. There is a critical need to increase awareness of skin diseases, or skin health promotion, which supports changing of the health-seeking behaviour for skin conditions. This will aid in early detection and treatment of the skin NTDs, in addition to providing benefits for those affected by other skin diseases. Educational opportunities should be utilized to their utmost. One would be associated with WASH strategies, but careful messages need to be developed and delivered.

ConclusionsOur study helped quantify the information gaps that need to be addressed in order to create demand for integrated skin NTDs services in an endemic setting in Nigeria. Individual, structural and socioeconomic challenges to access and delivery of services were identified. Community and health care workers ’ empowerment and engagement through outreach and regular training, respectively may alleviate these challenges.

by Thomas Ploemacher, William R. Faber, Henk Menke, Victor Rutten, Toine Pieters Leprosy is a chronic infectious disease caused byMycobacterium leprae (M.leprae) and the more recently discoveredMycobacterium lepromatosis (M.lepromatosis). The two leprosy bacilli cause similar pathologic conditions. They primarily target the skin and the peripheral nervous system. Currently it is considered a Neglected Tropical Disease, being endemic in specific locations within countries of the Americas, Asia, and Africa, while in Europe it is only rarely reported. The reason for a spatial inequality in the prevalence of leprosy in so-cal...

Abstract The aim was to analyze the acceptability of chemoprophylaxis with single-dose rifampicin (PEP) in contacts, index leprosy cases, and health professionals and related factors that can influence adherence. A qualitative content analysis study was performed after application of semi-structured interviews according to the protocol proposed in the LPEP program (2016) drafted at Alta Floresta, Mato Grosso State, Brazil, in July 2016. Study participants included individuals with leprosy, contacts, and health professionals. The QRS NVivo software version 10 was used. A total of 80 individuals were contacted, incl...

Abstract This ecological study aims to analyze both the tendency and the characteristics of leprosy in the elderly population in the state of Bahia, 2001-2017. The tendency was analyzed through joinpoint regression. Epidemiological variables were also included in the study. The average detection rate was 38.73/100,000, with prevalence of men (45.19/100,000). A downward trend occurred in both genders, from 2004, with a greater magnitude in women (annual percent change [APC] = − 3.4%). Men presented higher proportions of the multibacillary forms and physical disabilities. The epidemiological scenario indicates the need...

Phenolic glycolipid I (PGL-I) is an abundant antigen on the Mycobacterium leprae cell wall, commonly used for operational classification of leprosy patients. Our aim was to develop PGL-I mimotopes with similar characteristics and functions of the native antigen. We have used a random peptide phage display (PD) library for selections against the monoclonal antibody anti-PGL-I. After three selection cycles, six peptides were identified. All sequences were interspersed by a spacer generating a chimeric peptide (PGLI-M3) that was artificially synthesized. The highly reactive peptide was submitted to a reverse PD selection with...

In this report, we describe the development of a leprosy skin test using M. leprae-specific antigens. We selected the chimeric LID-1 fusion protein, formulated to achieve maximum performance at a minimal dose, as a skin test candidate based on its ability to elicit delayed-type hypersensitivity (DTH) reactions in M. leprae immune guinea pigs in a sensitive and specific manner, i.e., with no cross-reactivity observed with other mycobacterial species. Importantly, evaluations in armadillos indicated that intradermal inoculation of formulated LID-1 could distinguish uninfected from M. leprae-infected animals manifesting with ...

CONCLUSIONS: Our results demonstrate that the NLRP3 inflammasome is inactive in leprosy, suggesting immune evasion of M. leprae. PMID: 32130367 [PubMed - as supplied by publisher]
