History Of

: In the last decade, several cases of cutaneous leishmaniasis (CL) have been recorded by the provincial health center of Mazandaran Province, northern Iran. However, there is no documented report of autochthonous CL in the province yet. The patient, a 59-year-old female, known case of diabetes mellitus, lived in rural area of Kiasar district (in eastern part of the Mazandaran) with 5 skin lesions suspected of having vasculitis, without history of traveling to the endemic areas of CL, was admitted to Imam Khomeini teaching hospital, Sari. To rule out CL, fine needle aspiration (FNA) procedure was used aseptically for the patient. Laboratory investigations showed Leishman bodies (amastigotes) by direct smear preparation and species identification confirmed Leishmania major (L. major) by polymerase chain reaction (PCR) molecular method. Accordingly, this is the first documented report of autochthonous CL in Mazandaran Province. Overall, due to the abundance of probable rodent reservoir hosts and confirmation of infection of sandflies (Phlebotomus papatasi) with L. major in the Kiasar district, where our patient was living there, it seems that CL emerged in the eastern part of the province. Therefore, further studies on rodents and sandflies fauna in terms of emerging leishmanial infection in the area is recommended.

Background: Zoonotic cutaneous leishmaniasis caused by Leishmania major is endemic in 17 of 31 Iranian provinces. Various species of rodents have been introduced as the main reservoirs of the disease. This study was conducted to de­termine the natural infection of hedgehogs with Leishmania spp. in an endemic area of the disease, northern Iran. Methods: Fifteen long-eared hedgehogs were captured alive during 18 months study period, from Apr 2015 to Sep 2016, in Damghan City, Semnan Province, Iran. The animals were identified using apparent characteristics and to de­termine the Leishmania infection, impression smears were prepared from their ear lobes, hind feet, livers, and spleens. Micro­scopic examination and semi-nested PCR were applied to determine the infection and to identify the parasites species respectively. Results: All examined animals were identified as Hemiechinus auritus (Family: Erinaceidae). In microscopic examina­tion, 8 (53.3%) samples were shown to be infected with Leishmania parasites. The higher and lower rate of the infection was observed in the ears as well as the feet and in the liver specimens, 53.3%, and 33.3% respectively. Forty percent (6/ 15) of the samples were molecularly positive and all were identified as L. major parasites. All the examined animals in au­tumn and 50% of them in summer were shown to be infected with Leishmania parasites. Conclusion: This study demonstrated the natural infection of H. auritus with L. major for the first time in Damghan City and introduced these mammals as new potential reservoirs of ZCL in the study area.

Abstract Background Leishmaniasis is not endemic in Japan, and imported cases are rare. However, there are increasing concerns regarding imported cases of cutaneous leishmaniasis from endemic countries to Japan. This report describes a case of imported cutaneous leishmaniasis that was diagnosed and treated in Japan. Case presentation A 53-year-old Pakistani man presented with skin lesions on both malleoli of his right ankle and the dorsum of the left foot. The skin lesions manifested as erythematous nodules surrounding an ulcer in the center of the lesion. The lesions of the malleoli of his right ankle each measured 3 × 3 cm, and the lesion on the top of his left foot measured 5 × 4 cm. He had been living and working in Japan but had a history of a visit to Pakistan for about 2 months in 2018. The skin lesions were biopsied. Giemsa and hematoxylin and eosin staining of biopsy samples showed amastigotes of Leishmania in macrophages, and the presence of Leishmania was confirmed by skin tissue culture. Polymerase chain reaction using biopsy specimens identified Leishmania parasites, and DNA sequence analysis revealed that the species was Leishmania tropica. The patient was treated with intravenous liposomal amphotericin B for 6 days. The erythema disappeared, and the erythematous nodules resolved within 3 weeks. Conclusion This is the first report of imported cutaneous leishmaniasis caused by L. tropica from Pakistan, and it is interesting that all three testing modalities showed positive results in this case.

ABSTRACT Cytokine-inducible (or type 2) nitric oxide synthase (iNOS) is indispensable for the resolution of Leishmania major or Leishmania donovani infections in mice. In contrast, little is known about the expression and function of iNOS in human leishmaniasis. Here, we show by immunohistological analysis of skin biopsies from Mexican patients with local (LCL) or diffuse (DCL) cutaneous leishmaniasis that the expression of iNOS was most prominent in LCL lesions with small numbers of parasites whereas lesions with a high parasite burden (LCL or DCL) contained considerably fewer iNOS-positive cells. This is the first study to suggest an antileishmanial function of iNOS in human Leishmania infections in vivo.

Serological assays have been extensively evaluated for diagnosis of visceral leishmaniasis (VL) and considered as a routine method for diagnosis of VL while these methods are not properly evaluated for diagnosis of cutaneous leishmaniasis (CL). This study aimed to assess the performance of indirect immunofluorescent-antibody test (IFA) and enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of cutaneous leishmaniasis in Iran. Sixty-one sera samples from parasitologically confirmed CL patients and 50 sera from healthy controls along with 50 sera from non-CL patients were collected. Antigen was prepared from promastigotes and amastigotes ofLeishmania major. IFA was used to detect anti-LeishmaniaIgG while ELISA was used to detect anti-LeishmaniaIgM, total IgG, or IgG subclasses (IgG1 and 4). ELISA, for detection of total IgG and IgM, showed sensitivity of 83.6% and 84.7% and specificity of 62.7% and 54.6%, respectively. Sensitivity and specificity of ELISA for detecting IgG1 and IgG4 were 64%, 75% and 85%, 49%, respectively. Sensitivity and specificity of IFA were 91.6% and 81%.Conclusion. Findings of this study demonstrated that serological test, especially IFA, can be used for proper diagnosis of CL.

Lesion features in cutaneous leishmaniasis (CL) depend on the infecting Leishmania species as well as on host immune reponse. In this study, we evaluated the histological and immunological differences between two forms of CL described in Tunisia: zoonotic cutaneous leishmaniasis (ZCL) caused by L. major and sporadic cutaneous leishmaniasis (SCL) caused by L. infantum. Histological analysis showed a mild to moderate infiltrate within ZCL lesions. In contrast, massive infiltration of the dermis was observed within SCL lesions. Contrary to ZCL, infiltrates within SCL lesions were organized and showed granuloma composed of macrophages and lymphocytes. In addition, immunohistochemical analysis showed a predominance of CD4+ T cells within both CL forms. Furthermore, expression of interferon-γ, interleukin (IL)-10, IL-8, IL-13 and monocyte chemotactic protein (MCP)-1 was evaluated using real-time quantitative polymerase chain reaction (RT-qPCR). MCP-1 and IL-10 were expressed at comparable levels in ZCL and SCL lesions. Interestingly, IL-8 mRNA levels were significantly higher in ZCL lesions compared to SCL lesions, but interferon-γ was significantly higher in SCL lesions than in ZCL lesions.

Background: Leishmaniasis is a zoonotic disease and its the known as a health problem in all of the world. Case presentation: The patient, a 47-year-old man car driver from city of Bostan abad, with a history of traveling to cutaneous leishmaniasis endemic provinces last year, was referred to city health center with a 17 mm, no discharge and pus with necrotic appearance skin lesion. Biochemical, hematological parameters and urine culture and analysis were normal. Three smears was prepared with sterile vaccinostyle from the margins of wound and transferred to specific medium in sterile conditions. After staining the prepared smears from the wound, amastigotes with large nucleus and small kinetoplast in macrophages and active promastigotes in the liquid phase of medium were observed. Polymerase chain reaction (PCR) was performed using ITS-1 by specific primers. In the PCR product electrophoresis were compared with the marker bands and 350 bp band weight determined. With electrophoretic pattern and comparison with positive control band, isolates parasites belonged to Leishmania genus. In order to definitively diagnose the parasite species, sequencing method was used. The results showed 99% homology with Leishmania major. Finally, the patient with a diagnosis of rural cutaneous leishmaniasis was induction with Glucantime drug. Conclusion: Diagnosis of suspected cases with cutaneous leishmaniasis is the major importance. If an infected patient is diagnosed in the early stages of the disease, can be prevented the extent of the scar after recovery, as well as the possible complications of rural infection.
