Archival, paleopathological and aDNA-based techniques in leprosy research and the case of Father Petrus Donders at the Leprosarium ‘Batavia’, Suriname

ConclusionWe found no evidence that Donders contracted leprosy despite years of intense leprosy contact, but we successfully isolated an archaeological M. leprae aDNA sample from a control skeleton from South America.SignificanceWe successfully genotyped recovered aDNA to a M. leprae strain that likely originated in West Africa. The detected human mitochondrial haplogroup L3 is also associated with this geographical region. This suggests that slave trade contributed to leprosy in Suriname.LimitationsA limited number of skeletons was examined.Suggestions for further researchBroader review of skeletal collections is advised to expand on diversity of the M. leprae aDNA database.

We report the case of a 48-year old woman with long-standing lepromatous leprosy of 15 years of evolution, with a bacterial index of 4 in the direct smear and the initial skin biopsy. The patient was treated with multidrug therapy for 32 months although the treatment recommended by the World Health Organization (WHO) is only for 12 months. A skin biopsy was taken to determine if there was an active disease. We observed a diffuse dermal inflammation with numerous foreign body giant cells and vacuolated macrophages (Virchow´s cells). These cells contained granular acid-fast material that was also positive with immunohi...

Semin Neurol 2019; 39: 462-471 DOI: 10.1055/s-0039-1687884Leprosy is a challenging international health concern. Despite tremendous efforts in reducing worldwide disease prevalence in the past decades, some countries remain endemic and are plagued by high levels of disability. The neurological complications of leprosy are varied and complex, with current research focused on evaluating tools for earlier diagnosis of neuropathy, especially in resource-limited countries. While treatment with multidrug therapy is highly effective, active research aims to simplify regimens to improve adherence, minimize adverse effects, and pre...

CONCLUSION: It was concluded that the applied workshops enabled building knowledge and demystifying myths and stigmas socially constructed to adolescents, as well as allowed Nursing students to experience educational interventions on leprosy with adolescents. PMID: 31531670 [PubMed - in process]

CONCLUSION: Leprosy is greatly affected by the social context in which the patient is inserted, the chances of exposure to illness are the result of a set of not only individual aspects, but also of contexts or collective conditions. It is imperative for Nursing, as an essential part of the multiprofessional team entrusted with the care and surveillance of the disease, to recognize these factors to predict unfavorable outcomes and to develop new practices capable of reducing inequities.

Abstract OBJECTIVES: to identify scientific evidence in the literature regarding educational actions on leprosy developed with adolescents. METHOD: an integrative review of the literature, with the following research question: what are the leprosy educational practices currently being developed with adolescents? The search was performed in the following databases: MEDLINE, Scopus, LILACS, CINAHL, BVS Hanseníase and other sources, using "adolescent"; "leprosy"; "health education"; "public health", and "public health practice" as keywords. Results: the sa...

Abstract OBJECTIVE: to analyze the temporal trend and epidemiological patterns of leprosy indicators in Sobral, a municipality countryside of the state of Ceará, from 2001 to 2016. METHOD: a time series study based on data from the Department of Informatics of the Unified Health System. The time trend analysis was performed using the join point regression model. RESULTS: There were 2,220 new cases of leprosy in Sobral from 2001 to 2016. Of these, 158 (7.2%) in children younger than 15 years of age, the proportion of new male cases was 52.8% (1,162), cases with grade 2 were 7.0% (156), and proporti...

Conclusions/SignificanceOur finding suggests that synergetic associations of activating and inhibitoryKIR genes may alter the balance between these receptors and thus interfere in the progression of multibacillary leprosy.

To expedite this ‘timely diagnosis’, and that also at an early stage, here an attempt is made to fabricate an epitope-imprinted sensor. A molecularly imprinted polymer nanoparticles modified electrochemical quartz crystal microbalance sensor was developed for sensing of mycobacterium leprae bact...
