PY - 1998/1/1. Y1 - 1998/1/1. N2 - There is no clear understanding of the outcome of reinfection in New World cutaneous leishmaniasis, and its role in the relationship to the development of protection or secondary disease. For this reason, reinfection experiments with homologous (Leishmania panamensis-L. panamensis) and heterologous (L. major-L. panamensis) species of leishmaniae were conducted in the hamster model. The different protocols for primary infections prior to the challenge with L. panamensis were as follows: (a) L. major, single promastigote injection, (b) L. major, three booster infections, (c) L. panamensis, followed by antimonial treatment to achieve subclinical infection, (d) L. panamensis, with active lesions, (e) sham infected, naive controls. Although all reinfected hamsters ...
Cutaneous leishmaniasis is an infection caused by various species of Leishmania protozoa and is endemic in more than 70 countries throughout Latin America, Asia, Middle-East and southern Europe. The global number of reported cases has increased in the past decades because of improved diagnosis and case notification, but also because of drug resistance and inadequate vector control as a result of urbanisation and deforestation.1Leishmania parasites are transmitted by sandflies belonging to either Phlebotomus spp (Asia, Europe, Middle-East and North-Africa) or Lutzomya spp (Central and South America). The ecological context of the transmission cycles between the Old World (i.e., Africa, Asia and Europe) and the New World (i.e., the Americas) is different. New World cutaneous leishmaniasis is mostly associated with forests, whereas an open semi-arid climate is the transmission environment for Old World cutaneous leishmaniasis. There are 17 different Leishmania species that can cause different ...
Abstract: : Purpose: Cutaneous Leishmaniasis remains endemic in many regions of the world. The purpose of this study is to report the ocular complications of cutaneous Leishmaniasis. Methods: Seven patients from the southern region of Saudi Arabia presented to The Eye Center in Riyadh, Saudi Arabia. Five patients complained of decrease in vision in both eyes, two patients presented with lid deformity, and one patient complained of redness of the eye. History of cutaneous ulcers over the cheeks elicited in five patients, and two patients had cutaneous ulcers over the arms and cheek. Cutaneous ulcers appeared 6-12 months prior to the onset of ocular symptoms, and healed leaving scars. Laboratory work-up for uveitis, interstitial keratitis, and phlyctenulosis were negative. Results: There were five males and two female patients with an age range of 15-70 years and a mean age of 26 years. The clinical findings of cutaneous Leishmaniasis included ectropion of the lower eyelid with exposure ...
An effective adaptive immune response requires activation of specific CD4 T cells. The capacity of B cells to activate CD4 T cells in human cutaneous leishmaniasis caused by Leishmania (Viannia) has not been evaluated. CD4 T cell activation by B cells of cutaneous leishmaniasis patients was evaluated by culture of PBMCs or purified B cells and CD4 T cells with Leishmania panamensis antigens. CD4 T cell and B cell activation markers were evaluated by flow cytometry and 13 cytokines were measured in supernatants with a bead-based capture assay. The effect of Leishmania antigens on BCR-mediated endocytosis of ovalbumin was evaluated in the Ramos human B cell line by targeting the antigen with anti-IgM-biotin and anti-biotin-ovalbumin-FITC. Culture of PBMCs from cutaneous leishmaniasis patients with Leishmania antigens resulted in upregulation of the activation markers CD25 and CD69 as well as increased frequency of CD25hiCD127- cells among CD4 T cells. Concomitantly, B cells upregulated the costimulatory
Genetic factors play a crucial role in host susceptibility or resistance to infectious diseases. Variations within the SLC11A1 gene were assessed in this study with respect to cutaneous leishmaniasis in Pakistan which has not been reported before from this region. A total of eight polymorphisms present in SLC11A1 gene were analyzed and their possible role in disease association and linkage was tested.. Six of these genetic variations (rs2276631, rs2290708, rs3731864, rs201565523, rs17235409 and rs17235416) have been analyzed before in various populations with regard to leishmaniasis. In addition to these six SNPs, two polymorphisms, rs2695342 (825A/G) in exon 9 and rs17215556 (V443A) in exon 13, not investigated previously for their role in cutaneous leishmaniasis, were also included. The SNP rs2695342 (825A/G) in exon 9 alters the codon GCA to GCG. The resultant mutation is synonymous with no change in the amino acid alanine. Only the GG genotype was observed in all samples (cases and controls) ...
Abstract. This study describes the epidemiological and clinical characteristics of leishmaniasis and the pharmacological treatment of this disease in the municipality of Pueblo Rico, Risaralda, between January 2010 and December 2014. An observational study was conducted using information from the clinical records and epidemiological reports of patients diagnosed and confirmed with leishmaniasis of any age and sex, including sociodemographic, clinical, and pharmacological variables of the therapy received. Univariate and bivariate analyses were performed. A total of 539 cases of leishmaniasis were confirmed, with 29.5% occurring in children under 5 years of age. The median age was 10 years, with predominance in males (55.5%). The indigenous Emberá (aboriginal Americans) were the most affected (50.8%), and 93.3% of cases occurred in people living in scattered rural areas. All lesions corresponded to cutaneous leishmaniasis, of which 251 patients had compromise of the upper limbs (46.6%), 221 of the face
Abstract. Miltefosine has been used in the treatment of several new world cutaneous leishmaniasis (CL) species with variable efficacy. Our study is the first evidence on its clinical efficacy in Leishmania (Viannia) guyanensis. In this phase II/III randomized clinical trial, 90 CL patients were randomly allocated (2:1) to oral miltefosine (2.5 mg/kg/day/28 days) (N = 60) or parenteral antimony (15-20 mg/Sb/kg/day/20 days) (N = 30) according to age groups: 2-12 y/o and 13-65 y/o. Patients were human immunodeficiency virus (HIV) noninfected parasitological proven CL without previous treatment. Definitive cure was accessed at 6 months follow-up visit. No severe adverse events occurred. Vomiting was the most frequent adverse event (48.3%) followed by nausea (8.6%) and diarrhea (6.7%). Cure rates were 71.4% (95% confidence interval [CI] = 57.8-82.7) and 53.6% (95% CI = 33.9-72.5) (P = 0.05) for miltefosine and antimonial, respectively. There were no differences in cure rates between age groups within the
A research team at The University of Texas at El Paso is one step closer to developing an effective human vaccine for cutaneous leishmaniasis, a tropical disease found in Texas and Oklahoma, and affecting some U.S. troops stationed in Afghanistan and Iraq.. UTEP biological sciences doctoral student Eva Iniguez; her mentors Rosa Maldonado, Ph.D., and Igor Almeida, Ph.D.; and their teams and collaborators in Liverpool (Alvaro Acosta-Serrano, Ph.D.) and Saudi Arabia (Waleed Al-Salem, Ph.D.), recently published their research findings in PLOS Neglected Tropical Diseases, the first journal solely devoted to the worlds most neglected tropical diseases.. Leishmaniasis is caused by the protozoan leishmania parasites, which are transmitted by the bite of infected female phlebotomine sandflies - flies that are three times smaller than a mosquito. According to the World Health Organization, there are an estimated 700,000 to 1 million new cases annually, and they cause 20,000-30,000 deaths each year. The ...
Post-kala-azar dermal leishmaniasis (PKDL) is a recurrence of kala-azar that may appear on the skin of affected individuals months and up to 20 years after being partially treated, untreated or even in those considered adequately treated.[5][6] In Sudan, they can be demonstrated in up to 60% of treated cases. They manifest as hypopigmented skin lesions (such as macules, papules, nodules), or facial redness. Though any organism causing kala-azar can lead to PKDL, it is commonly associated with Leishmania donovani which gives different disease patterns in India and Sudan. In the Indian variant, nodules enlarge with time and form plaques but rarely ulcerate, but nodules from the African variety often ulcerate as they progress. Nerve involvement is common in African variety but rare in Indian subcontinent.[7] Histology demonstrates a mixture of chronic inflammatory cells; there can be macrophage or epitheloid granuloma.[8] Parasite concentration is not consistent among studies, perhaps reflecting ...

Background:The vector-borne cutaneous leishmaniasis (CL) is endemic in several regions of Pakistan mainly affecting poor populations. Host genetic factors, particularly SLC11A1 (solute carrier transmembrane protein) within macrophages, play a crucial role in disease pathology and susceptibility. Association of SLC11A1 with cutaneous leishmaniasis, a neglected tropical disease, is not well established. Inconsistencies have been observed within different populations worldwide with respect to genetic susceptibility. This study was designed to investigate genetic variation(s) in SLC11A1 and to assess possible association with cutaneous leishmaniasis in Pakistan. Results: Eight polymorphisms (rs2276631, rs3731864, rs2290708, rs2695342, rs201565523, rs17215556, rs17235409, rs17235416) were genotyped across SLC11A1 in 274 patients and 119 healthy controls. Six polymorphisms were studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing. Two single nucleotide
KEYWORDS: Leishmania; Swiss mice; Microbiota ; Germfree; Th1; Leishmaniasis. INTRODUCTION Leishmaniasis is a disease caused by parasites of the genus Leishmania that produce diversified clinical manifestation depending upon the characteristics of the parasite and on the immune response of the host2,5. The present understanding of the factors that lead to this diversity of clinical symptoms was obtained, in large part, through studies using isogenic mice experimentally infected with L. major. In these studies, the resistance to L. major is correlated with the development of Th1 CD4+ lymphocytes that produce high levels of IFN-g, a cytokine capable of activating macrophages to kill the intracellular forms of the parasite. On the other hand, susceptibility has been associated with the lack of IFN-g production and the presence of Th2 CD4+ lymphocytes that produce IL-4 which acts inhibiting the activation of macrophages12,18,23. There is, however, no report on infection of Swiss/NIH mice with L. ...

GOMES, Kirla Wagner Poti et al. Cutaneous leishmaniasis in a patient with ankylosing spondylitis using adalimumab. Rev. Bras. Reumatol. [online]. 2012, vol.52, n.3, pp.450-452. ISSN 0482-5004. http://dx.doi.org/10.1590/S0482-50042012000300014.. Leishmaniasis is an anthropozoonosis caused by species of Leishmania and can have different clinical presentations, depending on the parasite-host relationship. Tumor necrosis factor-α (TNF-α) is a cytokine essential to infection control, especially against intracellular parasites such as Leishmania. Anti-TNF-α strategies have had a marked impact on the treatment of rheumatic diseases, but the clinical use of those antagonists has been accompanied by an increased report of infections. We report the first case of cutaneous leishmaniasis in a patient with ankylosing spondylitis treated with adalimumab and methotrexate in Brazil. We believe that, in this case, there was no association between the anti-TNF-α treatment and cutaneous leishmaniasis, ...

The early events of leishmania infection are important in determining control or evolution of the disease. It is well known that the cure of leishmaniasis depends on the appropriate activation of the parasitized macrophages by IFN-γ secreted by Th1 lymphocytes, under the influence of IL-12 and IL-18 (27). When the protozoan encounters a favorable environment for producing Th2 cytokines, such as IL-4, IL-10 and IL-13, which are natural antagonists of the Th1 immune response, the multiplication of leishmania is enhanced and infection evolves into the disease (15, 16, 18, 27). IgE antibodies are produced in the Th2 immune response and have been used in serodiagnosis and also as indicators of the disease activity in toxoplasmosis, cerebral malaria, and VL (2, 22, 28).. CL is a clinical form of the leishmanial infection characterized by an evident Th1 type of immune response, documented by lymphocyte proliferation and IFN-γ secretion. However, high levels of parasitic-specific serum IgE without ...
Infection by protozoa haemoflagates of the genus leishmania can cause a wide range of clinical syndromes which are grouped together as visceral, cutaneous, or mucocutaneous disease.1 Imported leishmania infection is on the increase as a result of increased travel to endemic areas and adventure tourism.. There are at least 30 species of leishmania of which 12 named and several un-named affect man.2 The protozoa are intracellular (amastigote) in rodents and dogs, which act as a reservoir, and there is an extracellular form (promastigote) in sandflies, which are the vector.. The mucocutaneous form of the disease is almost exclusively restricted to South America where it is known as espundia. Untreated, this can lead to gross nasal oral and laryngopharyngeal destruction and death. All reported cases in the UK have been in travellers from South America.3,4 The protozoon responsible is commonly L braziliensis, and rarely L panamensis or L guyanesis, which are only found in South America..

Leishmaniasis is a vector-borne disease that distresses millions in the poorest regions of the globe. There are no anti-Leishmania vaccines approved for human use. Mice pre-exposed to uninfected sand fly bites (USFB) are protected against cutaneous leishmaniasis (CL). To test if pre-exposure to USFB protects rhesus monkeys against CL, we first developed a model where monkeys challenged with 50 L. major-infected Phlebotomus duboscqi sand flies developed self-healing cutaneous lesions mimicking human CL. In a following experiment, we exposed animals 3 times, every 21 days, to 20 uninfected P. duboscqi. We found that 70% of the monkeys reacted to USFB(DTH reaction and antibodies). Twenty-one days after the last exposure to USFB naïve, pre-exposed reactive (PE-R) and pre-exposed non-reactive monkeys were challenged with 50 L. major-infected P. duboscqi. We observed a reduction in disease burden and healing time in the PE-R group. This protection correlated with a two log reduction in parasite load ...

Neutrophils, by interacting with monocytes, dendritic cells, T cells, and B cells, through cell-cell contact or secreted products, drive inflammatory responses involved in host defense and tissue repair (7). Neutrophils have been shown to play an active role in the control of infections with specific and distinct pathogens such as Legionella (17), Toxoplasma (27), Mycobacterium (28), Entamoeba (29), Histoplasma (30), and Cryptosporidium (31). BALB/c mice infected in the ear dermis with L. braziliensis develop cutaneous lesions at the site of inoculation and histological analyses of infected ear sections have demonstrated a constant recruitment of neutrophils to the inoculation site (14). Since in this experimental model ear lesions heal spontaneously, we hypothesized that neutrophils exert a protective effect. Data presented herein collectively indicate that live neutrophils play an important yet unresolved role during experimental infection with Lb: in vivo neutrophil depletion increased lesion ...

Infections caused by the protozoan leishmania represent a wide range of diseases, including CL, mucocutaneous leishmaniasis (ML), and visceral leishmaniasis (VL) [10]. The disease is endemic in 88 countries of southern Europe, Central and South America, Africa, the Middle East and the Indian subcontinent. More than 350 million men, women and children are at risk of leishmaniasis worldwide [11]. The are 12 million individuals suffering from the disease worldwide, with half a million new cases of VL and 1.5 million cases of CL registered annually [11]. The incidence of infections caused by leishmania in HIV-infected patients is increasing throughout the world [12].. Although VL is the most frequent form of leishmania infection seen in HIV-infected patients, CL and HIV co-infections are also becoming frequent in these individuals [12]. CL manifests as single or multiple papules, nodules or plaques, which are non-itchy, painless and with or without ulceration, usually over exposed areas of the body ...
Activated CD4(+) T helper cells (Th) comprise at least two functionally distinct subsets, Th1 and Th2, which mediate different immunological effector functions. Experimental leishmaniasis is widely used to study the effector function of Th cell subsets in vivo. Healing and nonhealing Leishmania major infections have been correlated with polarized Th1 and Th2 responses, respectively. In the study presented here, a stable cell surface marker expressed on Th2 cells, T1/ST2, has been used to assess the distribution of CD4(+)T1/ST2(+) T cells in different organs of healer and nonhealer strains of mice during the course of L. major infection. The frequency of CD4(+) T cells expressing the T1/ST2 cell surface marker and Th2 cytokines in the lymphoid organs was low in both strains of infected mice; however, CD4(+) T1/ST2(+) T cells could be enriched from the lymphoid organs of infected nonhealer but riot from healer strains of mice. The highest frequency of CD4(+) T1/ST2(+)T cells was detected in the ...
