Abstract
Cutaneous leishmaniasis (CL), caused by an obligate intracellular protozoan parasite from the genus Leishmania, imposing a significant burden on underdeveloped countries especially those located in the Middle East. Four electronic databases were searched to evaluate the prevalence of CL in the Middle East. The random effects model (95% confidence intervals (CI)) were applied to determine the overall and subgroup pooled prevalence. Heterogeneity was assessed by Cochran's Q test and I2 statistics. Among 2424 peer-reviewed papers, 37 datasets from 34 studies were included in the current meta-analysis. 285560 individuals were assessed across 9 Middle Eastern countries. The pooled prevalence of CL was estimated at 12% (95% CI 9-15 %; 10718/285560). The highest prevalence rate was observed in Syria (39%, 37-42%), and the lowest one was found in Iraq and Lebanon (0%, 0-1%). The prevalence of CL in studies that applied LST assays had the highest rate (48%, 17-80%). The infection rate in males was similar to females (7%, 4-10%). The prevalence of infection in individuals living in urban areas was higher than in rural areas (14%, 10-19%). The prevalence of CL in the age group 0-15 years was higher than in individuals 16-40 and >40 years (9%, 6-13%). Most of the lesions were found on the face, and single lesions were more prevalent than two and three ones. In conclusion, the occurrence of CL was considerable in Middle Eastern countries. Therefore, more efforts should be made to precisely report the CL in this region for developing appropriate preventive and controlling strategies. .

Pharmaceuticals (Basel) 2022; 15:ph15081005. [PMID: 36015153 PMCID: PMC9415556 DOI: 10.3390/ph15081005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 07/09/2022] [Accepted: 07/15/2022] [Indexed: 11/24/2022] Open
Abstract
Leishmaniasis is affirmed as a category one disease (most emerging and unmanageable) by the World Health Organization (WHO), affecting 98 countries with an annual global incidence of ~1.2 million cases. Options for chemotherapeutic treatment are limited due to drug resistance and cytotoxicity. Thus, the search for new chemical compounds is instantly desirable. In this study, we used two compounds, i.e., 10-hydroxy chondrofoline and tafenoquine, for their antileishmanial activity against L. tropica (HTD7). First, the cytotoxicity assay of the test compounds against THP-1 cells was carried out, and these compounds were found safe. Intra-THP-1 amastigote activity (in vitro) was performed, which was then followed by the in vivo activity of 10-hydroxy chondrofoline in the murine cutaneous leishmaniasis (CL) model. A total of three concentrations were used, i.e., 25, 50, and 100 µM, to check the in vitro activity of the test compounds against the amastigotes. 10-hydroxy chondrofoline was found to be the most potent compound in vitro (and thus was selected for in vivo studies) with an LD50 value of 43.80 µM after 48 h incubation, whilst tafenoquine had an LD50 value of 53.57 µM. In vivo activity was conducted by injecting 10-hydroxy chondrofoline in the left hind foot of the infected BALB/c mice, where it caused a statistically significant 58.3% (F = 14.18; p = 0.002) reduction in lesion size (0.70 ± 0.03 mm) when compared with negative control (1.2 ± 0.3 mm).

Sand fly bioecological aspects and risk mapping of leishmaniasis by geographical information systems approach in a mineral exploration area of Brazil. Acta Trop 2022; 232:106491. [PMID: 35504313 DOI: 10.1016/j.actatropica.2022.106491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 04/25/2022] [Accepted: 04/27/2022] [Indexed: 11/29/2022]
Abstract
Epidemiological studies of leishmaniasis in areas of great human influence and environmental change serve as important tools for the implementation of effective control plans. Mining is currently a major economic activity in Brazil with the municipality of Pains, in the state of Minas Gerais, being one of the main lime producing municipalities in the country. This study aimed to map areas of potential transmission risks within the municipality of Pains using an epidemiological approach in association with the ecological study of sand flies. Twelve samplings carried out between May 2015 and April 2016 collected a total of 12,728 sandflies, comprising 2,854 females (22.42%) and 9,874 males (77.58%), of 20 species belonging to ten genera. The most abundant species was Lutzomyia longipalpis (80%). Leishmania DNA was detected in seven pools of female sand flies with an infection rate of 0.37%. Geoprocessing and the use of maps revealed that vector sand flies are distributed throughout the urban area, as are cases of canine and human leishmaniasis. However, the greatest abundances of sand flies were at sampling points at the border of the urban area. Higher densities of sand flies and the presence of Leishmania DNA may be correlated with extensive degradation by limestone mining. Integrated and multidisciplinary research approaches are necessary to better understand how the impacts of environmental change influence these insect vectors of leishmaniasis.

Abstract
Sand flies are often collected in urban areas, which has several implications for the risk of transmission of Leishmania Ross, 1903, to humans and other mammals. Given this scenario, we describe the sand fly fauna of caves and their surroundings in Mangabeiras Municipal Park (MMP) and Paredão Serra do Curral Park (PSCP), both located in the urban area of Belo Horizonte, Minas Gerais, Brazil, an endemic focus of visceral and cutaneous leishmaniasis. Collections were conducted monthly from November 2011 to October 2012, using CDC light traps exposed for two consecutive nights in four caves and their surroundings. Nonsystematized collections using Shannon traps and active searches were also performed around the caves. The presence of Leishmania DNA in collected female sand flies was evaluated by ITS1-PCR. A total of 857 sand flies representing fourteen species were collected in MMP, of which Evandromyia edwardsi (Mangabeira, 1941) was the most abundant. Leishmania amazonensis was detected in Brumptomyia nitzulescui (Costa Lima, 1932) and Ev. edwardsi, with the latter also having Leishmania braziliensis, Leishmania infantum, and Leishmania sp. A total of 228 sand flies representing four species were collected in PSCP, of which Sciopemyia microps (Mangabeira, 1942) was the most abundant. No females from PSCP were positive for Leishmania-DNA. Studies aimed at describing sand fly faunas of cave environments and detecting Leishmania are essential to understanding the relationship between these insects and this ecotope and assessing and monitoring areas that may pose risks to the health of visitors and employees.

CHILD ABUSE & NEGLECT 2021; 119:104628. [PMID: 32739068 PMCID: PMC7388819 DOI: 10.1016/j.chiabu.2020.104628] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 07/05/2020] [Accepted: 07/09/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND The Syrian crisis, which started in March 2011, has resulted in the displacement of 6.3 million refugees predominantly to neighboring countries in addition to the internal displacement of 6.2 million people. Turkey is the country hosting the largest number of refugees in the world with 3.6 million Syrian refugees 46 % of which are under 18 years old. OBJECTIVE The purpose of this article is to conduct a narrative review and analyze the vulnerabilities of refugee children in Turkey from the lens of the Sustainable Development Goals (SDG), more specifically SDG Goal 3: Good Health and Wellbeing, with a specific focus on Syrian refugee children. Moreover, this article explores the actions taken to prevent and mitigate issues that arise from these vulnerabilities. METHOD This narrative review article collected data from various primary and secondary sources on the Turkish refugee framework including national and international legislation, governmental and non-governmental data and reports, and scientific papers. RESULTS Syrian refugee children in Turkey are facing a variety of risks in terms of their health and wellbeing including communicable and non-communicable diseases, post-traumatic stress disorder, depression, family violence, child labor, and child marriage. The measures taken for prevention and response by governmental and non-governmental entities are multilateral and aim to address issues from multiple perspectives including medical, psychosocial, child protection, and legal. CONCLUSIONS The interventions and restructuring of the health system in Turkey contribute to the SDG number 3 for refugee children. The existence of a legal system which enables refugee access to health, protection, and other social services is key to achieve this goal. However, the existing system could be improved especially through solidifying the legal basis and centralizing the implementation for child and refugee protection. The engagement of all stakeholders to improve the health and wellbeing of refugee children remains vital.

Abstract
AIMS Despite immunization appearing to be the most appropriate strategy for long-term control of the vector-borne leishmaniases, no sustainable vaccine is currently available against any form of leishmaniasis. We therefore evaluated, in the context of vaccine antigen candidates, antigen-specific immune response at various stages of cutaneous leishmaniasis (CL). METHODS AND RESULTS Peripheral blood mononuclear cells (PBMC) isolated from healthy volunteers and CL patients (caused by either Leishmania major or L tropica) were incubated with crude Leishmania proteins (soluble Leishmania antigen; SLA), single recombinant proteins (TSA, LeIF, LmSTI1) or chimeric fusion proteins (LEISH-F2 and LEISH-F3). The concentrations of immune modulatory cytokines were then determined. While we did not detect appreciable antigen-specific IL-5 secretion, SLA induced secretion of interleukin (IL)-10 in cultures from early active lesion CL patients and even from healthy individuals. Conversely, interferon (IFN)-γ responses to SLA and recombinant proteins followed a similar pattern, developing only in the late active CL lesion phase. Once established, antigen-specific IFN-γ responses persisted in cured CL patients. CONCLUSION Together, our results provide further insight into the development of immune responses during CL and further validate the selection of LEISH-F2 and LEISH-F3 as vaccine antigen candidates.

Abstract
BACKGROUND The Syrian conflict has led to a dramatic increase of Old World cutaneous leishmaniasis (CL), triggered by continuous population displacements, disrupted control programmes, poor shelter and sanitation. METHODS A retrospective patient record study was conducted at the Institute of Tropical Medicine and International Health in Berlin. Records of all refugees from Syria treated for CL between January 2015 and March 2020 were reviewed. RESULTS Twenty refugees from Syria were treated. Seventeen refugees (85%) had complex lesions, mainly due to previous therapy failure or localization on the face. A long disease duration (50% > 1 year), pronounced facial scarring (20%), recurrences (20%), or worsening of existing lesions (20%) were observed. Nine patients (45%) had been pretreated in Syria. Complete remission was achieved in 10 of 16 patients (63%) treated with perilesional antimony. Eight patients (40%) required systemic treatment, thereof four (20%) repeated systemic treatment. Eight patients (40%) reported a delay of therapy ≥3 months in Germany, thereof one patient with a delay of 12 months and one patient with a delay of 32 months. CONCLUSION Between 2015 and 2020, Syrian refugees presented with severe morbidities of CL frequently requiring systemic and even consecutive systemic treatments. We assume a combination of socioeconomic and environmental factors associated with the ongoing Syrian conflict and migration to be responsible for the complex clinical presentations in this case series. More attention should be drawn to the situation of Syrian refugees with CL in countries where they are displaced to.

Abstract
Background Anthropogenic climate change affects the burden of infectious diseases via several interconnected mechanisms. In recent years, there has been greater awareness of the ways in which climate-sensitive infectious diseases pose a growing threat to global public health. Objective This study aimed to categorize and describe the effects of climate change on infectious diseases with skin manifestations. Methods A scoping review of the MEDLINE and PubMed online databases for climate-sensitive infections was performed in February and March 2020. A representative selection of conditions with skin manifestations was included in this review. Results Several representative climate-sensitive infectious diseases were identified in each of the following categories: vector-borne infectious diseases, infectious diseases associated with extreme weather events, and infectious diseases linked to human migration. Conclusion Climate variables directly influence the survival and reproduction of infectious microorganisms, their vectors, and their animal reservoirs. Due to sustained warmer temperatures at higher latitudes, climate change has expanded the geographic range of certain pathogenic microbes. More frequent climate change-related extreme weather events create circumstances where existing infectious microorganisms flourish and novel infections emerge. Climate instability is linked to increased human migration, which disrupts health care infrastructure as well as the habitats of microbes, vectors, and animal reservoirs and leads to widespread poverty and overcrowding. Dermatologists should understand that climate change will affect the burden and geographic distribution of infectious diseases, many of which have cutaneous signs and might be encountered in their regular practice.

Abstract
PURPOSE Due to mass population movements driven by internal conflicts and wars, cutaneous leishmaniasis (CL) is becoming increasingly important in Turkey. This study is aimed at determining the clinical aspects, diagnosis and genotyping of CL patients coming to Turkey from abroad. METHODS In our study, the clinical materials obtained from the patients or sent for diagnostic purposes from other centers to our laboratory between years 2012 and 2016 were assessed retrospectively. In total, there were 38 patients from Syria, Iraq, Afghanistan, Iran, and Turkmenistan. RESULTS 29 (76%), 28 (73%) and 33 (87%) samples were positive by light microscopy, Novy-McNeal-Nicolle(NNN), and enriched medium, respectively. By ITS-1 gene region PCR, 31 (81%) of the cases were positive. 35 of the patients were tested positive by at least one of the diagnostic methods. By genotyping, 21 Leishmania tropica, 8 Leishmania major, 3 Leismania infantum, 2 Leishmania donovani, and 1 Leishmania aethopica were detected. CONCLUSION This study is aimed at informing the clinicians working in the field for the import CL cases and recording the changing epidemiological features of CL in the region as well as discussing the possible focus for L. aethiopica infection which has not been shown in the region before.
