Abstract
Many areas of Iran are endemic regarding Cutaneous leishmaniasis (CL) as a parasitic disease transmitted by a female sand fly vector's bite. The present study investigated the distribution of sand flies in Harand and Egieh in Isfahan province, Central Iran. Overall, 408 out of 1260 collected sand flies were identified morphologically, among which 353 and 55 were isolated from Harand and Egieh, respectively. Also, 66.4% and 33.6% of the sand flies were female and male, respectively. The most prevalent sand fly species were Phlebotomus papatasi (52%), followed by Ph. caucasicus (40.4%), Sergentomyia sintoni (4.9%), and Ph. kazeruni (0.7%). Among 180 molecularly-analyzed sand flies, 14 (7.77%) were found infected with L. major, with 9 out of 103 (8.73%) Ph. papatasi and 5 out of 75 (6.66%) Ph. caucasicus.

Abstract
BACKGROUND Our objective in this study is to determine the atypical clinical presentations of cutaneous leishmaniasis (CL) patients diagnosed in Şanlıurfa province. METHODS This retrospective study included 213 patients with atypical clinical presentations among 1751 patients diagnosed with CL between October 2019 and August 2022 in Şanlıurfa Oriental Boil Diagnosis and Treatment Center located in an endemic region for CL. RESULTS We found the prevalence of atypical CL to be 12.1%. The most common atypical lesions were lupoid 21 (9.8%), erysipeloid 16 (7.5%), impetiginous 16 (7.5%), recidivan 15 (7%), eczematous 15 (7%), ecthyma-like 13 (6.1%), pyoderma gangrenous-like 12 (5.6%), and sporotrichoid 12 (5.6%). Other lesions with atypical clinical presentations: chalazion-like, verrucous, dental sinus-like, psoriasiform, zosteriform, lymphoma-like, juvenile xanthogranuloma-like, volcano-like, paronychial, basal cell carcinoma-like, squamous cell carcinoma-like, herpes labialis-like, keratoacanthoma-like, chancriform, annular, lichenoid, mastocitoma-like, keloidal, epidermoid cyst-like, kaposi sarcoma-like, scar leishmaniasis, granulomatous cheilitis-like, mycetoma-like, molluscum contagiosum-like, discoid lupus erythematosus-like, and dermatofibroma-like. CONCLUSIONS In addition to the atypical clinical presentations previously reported, we also defined dermatofibroma-like, Kaposi sarcoma-like, dental sinus-like, juvenile xanthogranuloma-like, mastocytoma-like, and epidermoid cyst-like. It should be kept in mind that CL can clinically mimic many infectious, inflammatory, and neoplastic diseases, which should be considered in the differential diagnosis of long-term non-healing lesions, especially in endemic areas. Key message What is already known on this subject: CL is known as the great imitator disease in dermatology. What this study adds: In addition to the atypical clinical presentations previously reported, we also defined dermatofibroma-like, Kaposi sarcoma-like, dental sinus-like, juvenile xanthogranuloma-like, mastocytoma-like, and epidermoid cyst-like. How this study might affect research, practice, or policy: CL can clinically mimic many infectious, inflammatory and neoplastic diseases, which should be considered in the differential diagnosis of long-term non-healing lesions, especially in endemic areas.

Abstract
BACKGROUND Cutaneous leishmaniasis (CL) is a complex, multifactorial disease that results from environmental factors such as parasite polymorphism, phlebotomine vectors, and host genetic factors. Some studies have identified specific genetic factors that may be associated with cutaneous leishmaniasis. The objective of this research was to resolve the association of 8 cytokine polymorphisms, including TNF-α -308 A/G (rs 1800629), TNF-α -238 A/G (rs 361525), TGF-β1 -509 T/C (rs 1800469), TGF-β1+ 915 G/C (rs 1800471), IFN-γ -874 T/A (rs 2430561), IFN-γ -179 G/A (rs 2069709), IL-10 -819 C/T (rs 1800871), and IL-10 -592 A/C (rs 1800872) with susceptibility to CL. METHODS A total of 152 patients with designated CL and 100 healthy controls were selected from those referred to Sistan and Baluchestan hospitals. CL was diagnosed by microscopic examination of Giemsa-stained samples and culture. Leishmania species were identified using ITS2 gene PCR amplification with universal primers. Genetic polymorphism was determined by the ARMS PCR method on extracted genomic DNA of individuals. Eight SNPs cytokines were genotyped. RESULTS Most of the Genotypic and allelic frequency comparisons between patients with CL and healthy subjects showed no difference, except 3. Individual SNP analysis showed highest association of TGF-β1 -509 (rs1800469) -CC genotype (P = 0.03, OR = 7.05, 95 % CI = 3.3-15) with 5.7-fold increase, IFN-γ -874 (rs 2430561) -AA genotype (P = 0.04, OR = 4.72, 95 % CI = 1.6-14) with 4.2-fold increase, and IL10 -819 (rs1800871) -CC genotype (P = 0.05, OR = 3.63, 95 % CI = 2.5-5.3) with 1.9-fold increase, with CL. Odds ratios (ORs) and 95 % confidence intervals (CIs) were evaluated to assess the association power. CONCLUSION Our results conclude that rs1800469 (TGF-β1), rs2430561 (INF-γ), and rs1800872 (IL10) polymorphisms are associated with CL in southeastern Iranian people.

THE CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY = JOURNAL CANADIEN DES MALADIES INFECTIEUSES ET DE LA MICROBIOLOGIE MEDICALE 2024; 2024:4896873. [PMID: 38487175 PMCID: PMC10940013 DOI: 10.1155/2024/4896873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 02/22/2024] [Accepted: 02/29/2024] [Indexed: 03/17/2024]
Abstract
Cutaneous leishmaniasis is of particular importance in southern Iran. This study aimed to investigate the infection of rodents with Leishmania major in an urban area of Fars Province, located in southern Iran. Rodents were trapped and samples from the liver, spleen, and skin were collected. Impression smears were prepared from these tissues and any skin lesions and were examined microscopically. In addition, a portion of the samples were preserved for subsequent DNA extraction. A total of 41 rodents belonging to three species were caught from 10 trapping stations in gardens or houses within the area. The caught rodent species were Rattus rattus (n = 25, 60.97%), Mus musculus (n = 15, 36.58%), and Meriones persicus (n = 1, 2.5%). Leishmania amastigotes were seen in the spleen tissue smear of 6 (2.43%) of the rodents, including 4 of R. rattus and 2 of M. musculus. Skin lesions were observed on the muzzles of two R. rattus and one M. musculus. Samples taken from these lesions tested positive for Leishmania infection. Leishmania DNA was detected in 18 (43.9%) rodents, including 11 R. rattus, 6 M. musculus, and one M. persicus, based on DNA sequencing of the ITS2 gene and PCR of the kDNA. Phylogenetic reconstruction revealed that the parasite infecting the rodents was L. major. The detection of Leishmania infection in these rodents in urban areas raises concerns about the urbanization of cutaneous leishmaniasis caused by L. major. This urbanization poses unique challenges for control and prevention efforts.

Abstract
Leishmaniasis is a disease of poverty that imposes a devastating medical, social, and economic burden on over 1 billion people nationwide. To date, no in-depth study to analyze the major global challenges and needs assessment has been carried out. This investigation aimed to explore a comprehensive narrative review of leishmaniasis's main challenges and initially highlight obstacles that might impede the implementation of control measures. Also, we propose a specific list of priorities for needs assessment. The presence of socioeconomic factors, multiple clinical and epidemiological forms, various Leishmania species, the complexity of the life cycle, the absence of effective drugs and vaccines, and the lack of efficient vector and reservoir control make this organism unique and sophisticated in playing a tangled role to react tricky with its surrounding environments, despite extensive efforts and implementation of all-inclusive former control measures. These facts indicate that the previous strategic plans, financial support, and basic infrastructures connected to leishmaniasis surveillance are still insufficient. Strengthening the leishmaniasis framework in a context of accelerated programmatic action and intensification of cross-cutting activities along with other neglected tropical diseases (NTDs) is confidently expected to result in greater effectiveness, cost-benefit, and fruitful management. Sensitive diagnostics, effective therapeutics, and efficacious vaccines are vital to accelerating advancement toward elimination, and reducing morbidity/mortality and program costs. Collective actions devoted by all sectors and policy-makers can hopefully overcome technical and operational barriers to guarantee that effective and coordinated implementation plans are sustained to meet the road map for NTDs 2021- 2030 goals.

Abstract
Background Stem cell-derived secretome (SE) released into the extracellular space contributes to tissue repair. The present study aimed to investigate the impact of isolated secretome (SE) from adipose-derived mesenchymal stem cells (ASCs) on Leishmania major (L. major) lesions in BALB/c mice. Methods This experimental study was conducted at Ahvaz University of Medical Sciences (Ahvaz, Iran) in 2021. Forty female BALB/c mice were infected with stationary phase promastigotes through intradermal injection in the bottom of their tail and randomly divided into four groups (n=10 per group). The mice were given SE (20 mg/mL), either alone or in combination with Glucantime (GC, 20 mg/mL/Kg), meglumine antimoniate (20 mg/mL/Kg) for the GC group, and phosphate-buffered saline (PBS) for the control group. After eight weeks, the lesion size, histopathology, the levels of Interleukin 10 (IL-10), and Interleukin 12 (IL-12) were assessed. For the comparison of values between groups, the parametric one-way ANOVA was used to assess statistical significance. Results At the end of the experiment, the mice that received SE had smaller lesions (4.56±0.83 mm versus 3.62±0.59 mm, P=0.092), lower levels of IL-10 (66.5±9.7 pg/mL versus 285.4±25.2 pg/mL, P<0.001), and higher levels of IL-12 (152.2±14.2 pg/mL versus 24.2±4.4 pg/mL, P<0.001) than the control. Histopathology findings revealed that mice treated with SE had a lower parasite burden in lesions and spleen than the control group. Conclusion The current study demonstrated that ADSC-derived SE could protect mice infected with L. major against leishmaniasis.

Abstract
Cutaneous leishmaniasis can present in many different clinical forms. Diagnosis of atypical forms is often delayed. It is useful to keep in mind the diagnosis of cutaneous leishmaniasis, a mimicking disease, to reduce unnecessary treatment and patient morbidity. Erysipeloid leishmaniasis should be considered when presented as long-term erysipelas-like lesions that do not respond to antibiotics. We want to present our five patients with erysipeloid leishmaniasis, one of the atypical clinical forms.

Abstract
Iran has invariably been under the growing public health threat of cutaneous leishmaniasis (CL), a significant barrier to local development that hinders the prevention and control efforts toward eliminating the disease. So far, no comprehensive and in-depth epidemiological analysis of the CL situation has been carried out nationwide. This study aimed to employ advanced statistical models to analyze the data collected through the Center for Diseases Control and Prevention of Communicable Diseases during 1989-2020. However, we emphasized the current trends, 2013-2020, to study temporal and spatial CL patterns. In the country, the epidemiology of CL is incredibly intricate due to various factors. This fact indicates that the basic infrastructure, the preceding supports, and the implementation plan related to preventive and therapeutic measures need crucial support. The leishmaniasis situation analysis is consistent with desperate requirements for efficient information on the control program in the area. This review provides evidence of temporally regressive and spatially expanding incidence of CL with characteristic geographical patterns and disease hotspots, signifying an urgent need for comprehensive control strategies. This information could be a suitable model and practical experience in the Eastern Mediterranean Region, where over 80% of CL is reported.

Abstract
Leishmaniasis significantly affects the population of the tropics and subtropics. Clinical features and infective species of Leishmania are the primary factors driving the direction of diagnosis. The rise in incidences of atypical presentations present a challenge in patient treatment. Knowledge of unusual/rare presentations can aid in having a broader perspective for including the different aspects during the examination and thus avoid misdiagnosis. A comprehensive literature survey was performed to present the array of atypical presentations confounding clinicians which have been seen in leishmaniasis. Case reports of unusual findings based on the localizations and morphology of lesions and infective species and the predominant geographical sites over almost five decades highlight such presentations in the population. Information regarding the clinical features recorded in the patient and the chosen treatment was extracted to put forward the preferred drug regimen in such cases. This comprehensive review presents various unusual observations seen in visceral leishmaniasis, post-kala-azar dermal leishmaniasis, cutaneous leishmaniasis, and mucocutaneous leishmaniasis. It highlights the need to consider such features in association with differential diagnosis to facilitate proper treatment of the patient.

Trans R Soc Trop Med Hyg 2023; 117:38-44. [PMID: 36068660 DOI: 10.1093/trstmh/trac081] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 06/16/2022] [Accepted: 08/04/2022] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Both zoonotic cutaneous leishmaniasis (ZCL) and anthroponotic cutaneous leishmaniasis are endemic in different regions of Iran. It is important to know the type of cutaneous leishmaniasis (CL) for prevention strategies. On the other hand, Iran is one of the countries that was severely affected by the coronavirus 2019 (COVID-19) pandemic. However, little is known about the causative agents of CL during the COVID-19 pandemic in Iran. METHODS In this study, a total of 181 samples were isolated from patients with CL lesions in four different endemic cities of Iran (Jahrom, Juyom, Kashan and Shoushtar) during the COVID-19 pandemic (the summer and autumn of 2021). The nested-PCR targeting kinetoplast DNA (kDNA) minicircles was applied for species identification of the parasite and the internal transcribed spacer-1 (ITS-1) gene was applied for sequencing and phylogenetic analysis. RESULTS Molecular detection of kDNA minicircles revealed that all isolates from the four cities were Leishmania major, indicating the ZCL pattern. Ten isolates were sequenced by the ITS-1 gene and deposited in GenBank [accession numbers: OL627363-72]. Sequencing and phylogenetic analysis displayed a high similarity rate of the isolates with sequences from other parts of Iran and Iraq. Over half of the patients (53.59%) had a single lesion, while 17.12, 14.92, 2.21 and 12.16% of cases had two, three, four and more than four lesions, respectively. About half of the patients (50.27%) had lesions on their hands, while the rest had lesions on multiple locations (19.34%), legs (16.58%), face (9.94%), ears (1.66%) and waist (2.21%). CONCLUSIONS This study revealed the occurrence of ZCL during the COVID-19 pandemic in four endemic regions of Iran. Strategies for prevention and control of the disease should be considered to mitigate the occurrence of ZCL.

Evaluation of expression variations in virulence-related genes of Leishmania major after several culture passages compared with Phlebotomus papatasi isolated promastigotes. PLoS One 2023; 18:e0284240.

Abstract
Cutaneous leishmaniasis (CL) is a prevalent infectious disease with considerable morbidity annually. Here, we aimed to investigate the likely variations in gene expression of glycoprotein63 (gp63), heat shock protein 70 (HSP70), histone, arginase, cysteine protease B (CPB), Leishmania homologue of receptors for activated C kinase (LACK), small hydrophilic endoplasmic reticulum-associated protein (SHERP) in metacyclic promastigotes of L. major isolated from Phlebotomus papatasi sand flies and promastigotes excessively cultured in culture medium. The parasites were collected from suspected CL cases in Pasteur Institute of Iran, cultured and inoculated into the female BALB/c mice (2×106 promastigotes). Sand flies were trapped in Qom province, fed with the blood of euthanized infected mice and subsequently dissected in order to isolate the midgut including stomodeal valve. The metacyclic promastigotes were isolated from Ph. papatasi (Pro-Ppap) using peanut agglutinin test (PNA), then continuously cultured in RPMI-1640 medium enriched with fetal bovine serum, penicillin (100 U/ml) and streptomycin (100 mg/ml) to reach stationary phase (Pro-Stat). The gene expression was evaluated in both parasitic stages (Pro-Ppap and Pro-Stat) using qRT-PCR. Out results showed a significant increased gene expression at Pro-Ppap stage for gp63 (P = 0.002), SHERP (P = 0.001) and histone (P = 0.026) genes, in comparison with Pro-Stat stage. Noticeably, significant changes were, also, demonstrated in 10th to 15th passages [gp63 (P = 0.041), arginase (P = 0.016), LACK (P = 0.025)] and in 5th to 20th passage (SHERP) (P = 0.029). In conclusion, the findings of the present study seem to be essential in designing Leishmania studies, in particular regarding host-parasite interaction, immunization and infectivity studies.

Abstract
Leishmania parasites can cause zoonotic cutaneous leishmaniasis (CL) by circulating between humans, rodents, and sandflies in Iran. In this study, published data were collected from scientific sources such as Web of Science, Scopus, PubMed, Springer, ResearchGate, Wiley Online, Ovid, Ebsco, Cochrane Library, Google scholar, and SID. Keywords searched in the articles, theses, and abstracts from 1983 to 2021 were cutaneous leishmaniasis, epidemiology, reservoir, vector, climatic factors, identification, and Iran. This review revealed that CL was prevalent in the west of Iran, while the center and south of Iran were also involved in recent years. The lack of facilities in suburban regions was an aggravating factor in the human community. Some parts of southern Iran were prominent foci of CL due the presence of potential rodent hosts in these regions. Rhombomys opimus, Meriones lybicus, and Tatera indica were well-documented species for hosting the Leishmania species in Iran. Moreover, R. opimus has been found with a coinfection of Leishmania major and L. turanica from the northeast and center of Iran. Mashhad, Kerman, Yazd, and sometimes Shiraz and Tehran foci were distinct areas for L. tropica. Molecular identifications using genomic diagnosis of kDNA and ITS1 fragments of the parasite indicated that there is heterogeneity in leishmaniasis in different parts of the country. Although cutaneous leishmaniasis has been a predicament for the health system, it is relatively under control in Iran.

Abstract
The emergence of the Coronavirus Disease 2019 (COVID-19) pandemic has a considerable effect on the burden of other diseases. Cutaneous leishmaniasis (CL) is an endemic parasitic disease in Iran. Here, we report an outbreak of zoonotic cutaneous leishmaniasis (ZCL) during the COVID-19 pandemic in Jahrom county, which is an endemic region in the southwest of Iran. Before the pandemic, the annual occurrence of CL was less than 240 cases per year, while the number of cases increased to 307 and 771 cases in the first and second years after the pandemic, respectively. Molecular detection of some isolates identified Leishmania major. The rodent control program was completely interrupted during the first year of the COVID-19 outbreak in Jahrom (February to December 2020), then the program restarted again as routine from the summer of 2021 till now. Interrupted rodent control program along with inadequate screening programs of CL patients were probably one of the causes of this outbreak in Jahrom.

Abstract
OBJECTIVE To investigate the in vitro activity, synergism, cytotoxicity and cellular immunological response, as well as the molecular affinity between amphotericin B (AmB) and crotamine (CTA), derived from Crotalus durissus terrificus venom against Leishmania amazonensis. METHODS This study performed the inhibition of promastigotes and amastigotes' growth under different concentrations of the drug and pharmacological combinations (AmB + CTA) based on the Berimbaum method (synergism study). The lactate dehydrogenase (LDH) quantification method was used to determine the cytotoxicity of the drug and combinations employing four cell lines (J774, HepG2, VERO, and C2C12). Following, the levels of Tumour Necrose Factor-alpha (TNF-α) and Interleukin-12 (IL-12) cytokines, using enzyme-linked immunosorbent assay (ELISA) and nitrites, as an indirect measure of Nitric Oxide (NO), using the Griess reaction were assessed in the supernatants of infected macrophages. In silico approach (molecular docking and dynamics) and binding affinity (surface plasmon resonance) between the drug and toxin were also investigated. RESULTS CTA enhanced AmB effect against promastigote and amastigote forms of L. amazonensis, decreased the drug toxicity in different cell lines and induced the production of important Th1-like cytokines and NO by infected macrophages. The pharmacological combination also displayed consistent molecular interactions with low energy of coupling and a concentration-dependent profile. CONCLUSION Our data suggest that this pharmacological approach is a promising alternative treatment against L. amazonensis infection due to the improved activity (synergistic effect) achieved against the parasites' forms and to the decreased cytotoxic effect.

Abstract
Leishmaniasis is a neglected vector-borne disease caused by Leishmania parasites transmitted through the infected sand flies bite. Current treatments are limited, partly due to their high cost and significant adverse effects, and no human vaccine is yet available. Sand flies saliva has been examined for their potential application as an anti-Leishmania vaccine. The salivary protein, PpSP15, was the first protective vaccine candidate against L. major. Additionally, PsSP9 was already introduced as a highly immunogenic salivary protein against L. tropica. Herein, we aimed to develop an effective multivalent live vaccine to control Cutaneous Leishmaniasis induced by two main species, L. major and L. tropica. Hence, the two above-mentioned salivary proteins using T2A linker were incorporated inside the L. tarentolae genome as a safe live vector. Then, the immunogenicity and protective effects of recombinant L. tarentolae co-expressing PpSP15 and PsSP9 were evaluated in pre-treated BALB/c mice with CpG against L. major and L. tropica. Following the cytokine assays, parasite burden and antibody assessment at different time-points at pre and post-infection, promising protective Th1 immunity was obtained in vaccinated mice with recombinant L. tarentolae co-expressing PpSP15 and PsSP9. This is the first study demonstrating the potency of a safe live vaccine based on the combination of different salivary proteins against the infectious challenge with two different species of Leishmania.

Abstract
Leishmaniasis has been identified as a significant disease in tropical and subtropical regions of the world, with Iran being one of the disease-endemic areas. Various treatments have been applied for this disease, and amphotericin B (Amp B) is the second line of treatment. Side effects of this drug have been reported in various organs. The present study investigated the effects of different types of Amp B on fetal organs using in silico and in vivo assays (chicken embryos). In vivo analysis was done by checking pathological changes, angiogenesis, and apoptosis alterations on eggs treated by Amp B and AmBisome. In silico approach was employed to predict the affinity of Amp B and AmBisome to the vascular endothelial growth factor A (VEGF-A), its receptor (KDR1), apoptotic-regulator proteins (Bcl-2-associated X protein (Bax), B-cell lymphoma (Bcl-2), and Caspase-8. The ADME-toxicity prediction reveals that AmBisome possesses a superior pharmacological effect to Amp B. The best result of all the dockings in the Molegro Virtual Docker (MVD) was obtained between Bax, Bcl-2, Caspase-8, KDR1, and VEGF-A targets. Due to the lower Egap (HOMO–LUMO) of AmBisome, the chemical reactivity of AmBisome was higher than that of Amp B. In vivo analysis showed that embryos that received Amp B exhibited less vascular density than AmBisome. Amp B alone significantly increased the expression of apoptosis and decreased angiogenesis genes compared to AmBisome. The histopathology analysis of the treated embryos showed a reduction in the blood vessel collapse and an increase in degenerative and apoptotic–necrotic changes in the embryonic tissues. Overall, the results suggest the potential benefits of AmBisome over Amp B, which might be a better treatment strategy to treat leishmaniasis during pregnancy.

Abstract
Leishmaniasis is one of the common diseases transmitted by sand flies in tropical and subtropical regions of the world. Currently, antimonial derivatives are the first line of treatment. Some of the members of the ATP-binding cassette (ABC) family of Leishmania are shown to be associated with no response to treatment. In this study, we evaluated ABCI4, ABCG2, ABCC7, ABCB4, and ABCC3 genes expression in Leishmania isolated from patients with non-healing cutaneous leishmaniasis and treatment response isolates. We selected 17 clinical isolates including 8 treatment failure and 9 treatment response samples from September 2020 to March 2021. The isolates were obtained from patients of Health Center Laboratory of Varzaneh, Isfahan, Iran with cutaneous leishmaniasis. The diagnosis was performed using microscopic observation. The samples were directly collected from the lesions. The expression profiling of genes was assessed using SYBR Green real-time PCR that was analyzed with delta-delta Ct. All treatment failure clinical isolates were L. major. Gene expression analysis in treatment failure isolates showed that the ABC transported genes had a different pattern in each isolate. Treatment failure has been reported for cutaneous leishmaniasis worldwide. Knowledge of the molecular mechanisms of treatment failure could solve this problem. ABC transporter genes are considered controversial over the mechanisms of treatment failure outcomes. In this study, we showed that ABC transporter genes could be considered one of the important mechanisms.

Abstract
Background Leishmaniasis is a vector-borne disease that is endemic in the tropical and sub-tropical areas of the world. Low efficacy and high cytotoxicity of the current treatment regimens for leishmaniasis is one of the most important health problems. In this experimental study, anti-leishmanial effects of different concentrations of resveratrol and resveratrol nano-emulsion (RNE) were assessed. Methods RNE was prepared using the probe ultra-sonication method. The cytotoxicity was evaluated using the MTT technique on the L929 cell line. The anti-leishmanial activities on promastigotes of leishmania were assessed using vital staining and infected BALB/c mice were used to assess the in vivo anti-leishmanial effects. Results In vitro and in vivo assays revealed that all concentrations of resveratrol and RNE had valuable inhibitory effects against Leishmania major in comparison to the control group (P < 0.05). The half maximal inhibitory concentration (IC50) values were calculated as 16.23 and 35.71 µg/mL for resveratrol and RNE, respectively. Resveratrol and RNE showed no cytotoxicity against the L929 cell line. Conclusions According to the potent in vitro and in vivo anti-leishmanial activity of RNE at low concentration against L. major, we suggest that it could be a promising anti-leishmanial therapeutic against L. major in the future.

Abstract
Background Cutaneous leishmaniasis (CL) has been reported in recent years in South Khorasan Province, a desert region of eastern Iran, where the main species is Leishmania tropica. Little is known of the influence of geography and climate on its distribution, and so this study was conducted to determine geo-climatic factors by using geographic information system. Methods The home addresses of patients with CL patients who were diagnosed and notified from 2009 to 2017 were retrieved from the provincial health center and registered on the village/town/city point layer. The effects of mean annual rainfall (MAR) and mean annual humidity (MAH), mean annual temperature (MAT), maximum annual temperature (MaxMAT), minimum annual temperature (MinMAT), mean annual number of high-velocity wind days (MAWD), mean annual frosty days (MAFD) and snowy days (MASD), elevation, soil type and land cover on CL distribution were examined. The geographical analysis was done using ArcMap software, and univariate and multivariate binary logistic regression were applied to determine the factors associated with CL. Results A total of 332 CL patients were identified: 197 (59.3%) male and 135 (40.7%) female. Their mean age was 29.3 ± 2.1 years, with age ranging from 10 months to 98 years. CL patients came from a total of 86 villages/towns/cities. By multivariate analysis, the independent factors associated with increased CL were urban setting (OR = 52.102), agricultural land cover (OR = 3.048), and MAWD (OR = 1.004). Elevation was a protective factor only in the univariate analysis (OR = 0.999). Soil type, MAH, MAT, MinMAT, MaxMAT, and MAFD did not influence CL distribution in eastern Iran. Conclusions The major risk zones for CL in eastern Iran were urban and agricultural areas with a higher number of windy days at lower altitudes. Control strategies to reduce human vector contact should be focused in these settings. Graphical abstract ![]()

Abstract
BACKGROUND Anthroponotic cutaneous leishmaniasis (ACL) due to Leishmania tropica and zoonotic CL (ZCL) due to L major have different clinical and epidemiological features. OBJECTIVES To determine whether pro-inflammatory cytokines are involved in diverse pathogenicity of Leishmania species causing CL. PATIENTS/METHODS The capacity of L major/L tropica to modulate expression of IL-1β, IL-8 (CXCL8), IFN-γ, TNF-α and MCP-1 (CCL2) in peripheral blood mononuclear cells (PBMCs) and monocyte-derived macrophages (MDMs) was evaluated by real-time RT-PCR technique. RESULTS PBMCs from both ZCL and ACL cases expressed significantly higher IFN-γ (P < .001) and TNF-α (P < .05) compared with healthy controls (HC). PBMCs from ACL patients expressed significantly higher IL-1β and IL-8 compared with ZCL patients and HC when stimulated with live L major or L tropica promastigotes (P < .001). After 4 and 10 hours, L major-infected MDMs expressed significantly higher IFN-γ (P < .05), and after 10 hours, L tropica-infected MDMs expressed significantly higher IL-1β, IFN-γ and IL-8 compared with noninfected cells (P < .05). CONCLUSIONS This study shows differential parasite-mediated stimulations of the inflammatory response with L major vs L tropica ex vivo. Pro-inflammatory cytokines particularly IL-8 (CXCL8) and IL-1β might contribute in diverse clinical features of CL such as longer duration of lesion persistence in ACL patients.

Reemergence of zoonotic cutaneous leishmaniasis in an endemic focus, northeastern Iran. Parasite Epidemiol Control 2021; 13:e00206. [PMID: 33889761 PMCID: PMC8048008 DOI: 10.1016/j.parepi.2021.e00206] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Revised: 01/04/2021] [Accepted: 01/29/2021] [Indexed: 11/24/2022] Open
Abstract
Zoonotic cutaneous leishmaniasis (ZCL) is a form of disease, which is mostly caused by Leishmania major (L.major) in the Old World with high incidence through early life. Recently, the high incidence of CL has been reported in Jajarm County, northeastern Iran. The aim of the present study was to investigate the epidemiological aspects of CL and to identify Leishmania spp. in the area. Between 2012 and 2018, patients with active lesions suspected of CL were examined. Diagnosis was performed by methods of clinical examination and direct smears. Conventional kDNA polymerase chain reaction (PCR) was used to identify species of Leishmania. During the seven-year study period, 629 subjects were diagnosed as CL cases by clinical and microscopic examination. Considering the population of the study area, the average incidence rate was 237.8 per 100,000 population. Most (29.4%) of the subjects with ZCL were aged <10 years. Most of the patients (58.7%) were male and the rest were female. Most ulcers were observed on the face (32.2%) and hands (23.7%), respectively. Most patients (90%) had two or more ulcers on their body. The highest incidence was in the autumn in October (32%). Our data revealed that an ongoing reemergence of ZCL focus caused by L.major has arisen in the study area. Moreover, direct PCR on the smears for identifying Leishmania showed 100% specificity, and the species was identified as L. major using species -specific kDNA PCR. The use of conventional PCR on skin smears seems to provide a valuable method for confirming the clinical diagnosis of ZCL, which is very specific and sensitive particularly for clinical correlative studies. Further investigations are needed to improve planning strategies of vectors and reservoirs populations.

INFECTION GENETICS AND EVOLUTION 2020; 85:104533. [PMID: 32919066 DOI: 10.1016/j.meegid.2020.104533] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 08/30/2020] [Accepted: 09/03/2020] [Indexed: 02/07/2023]
Abstract
Cutaneous leishmaniasis (CL) is mainly caused by L. major and L. tropica in Old World and might be represented as typical skin lesion(s) or sometimes as a spectrum of atypical manifestations. We applied multilocus sequence typing (MLST) to explore genetic variations of Leishmania strains isolated from atypical vs. typical CL patients from Iran. A PCR-sequencing was performed for seven housekeeping genes (g6pd, mpi, asat, icd, 6pgd, fh, and trys) and genetic diversity indices and phylogenetic relationships were analyzed. A total of 41 isolates of L. major (28/41) and L. tropica (13/41) from 21 (51.2%) atypical CL and 20 (48.8%) typical CL cases were included. A set of additional sequences of 41 strains of 17 species of Leishmania were retrieved from databases. Different SNP variations were detected and the highest rate of heterozygous sites was found in g6pd and 6pgd genes (6 sites) for L. tropica and in asat and 6pgd genes (7 sites) for L. major strains. All strains were clustered into 58 unique sequence types (STs) including 17 STs related to 41 strains of Leishmania of this study. Concatenated tree clustered all strains in 6 main clades (A to F) including L. major (clade D) and L. tropica (clade B) strains. Two strains of L. major (codes 28 and 42) with highest nucleotide variations were more close to L. tropica and were grouped in Clade B. All of the STs were related in clonal complexes by using eBURST with the prediction of founder genotypes. A high rate of genetic variations and heterozygocity was evident in L. tropica and L. major strains; nevertheless, there was no significant difference in the diversity of Leishmania strains between typical CL and atypical CL groups. This study represents the first successful application of MLST approach to L. tropica and L. major strains in Iran.
