Treatment options for leishmaniasis.

2021

Leishmaniasis is broadly classified into three types: cutaneous, mucocutaneous and visceral. The visceral form is most dangerous and can result in death. Although leishmaniasis is an ancient disease, its treatment is still challenging. Several drugs, differing in their cost, toxicity, treatment duration and emergence of drug resistance, are used for different types of leishmaniasis. To overcome these limitations, the search for newer drugs and other treatments continues. In this article, we discuss conventional drugs, other treatments, including newer options such as immunotherapy and immunochemotherapy, and future prospects for leishmaniasis treatment.

Transfusion transmitted leishmaniasis. What to do with blood donors from endemic areas?

2014

Summary Leishmaniasis clinical spectrum ranges from cryptic infection to fatal visceral leishmaniasis. Cryptic infection can be found in blood donors from areas endemic for leishmaniasis all over the world. Although leishmaniasis is a classic vector-borne disease, cases of transfusion transmitted leishmaniasis have been reported especially in nonendemic areas. Most of these cases regarded infants or children. This paper reviews the literature on this specific feature and the impact of leishmaniasis on transfusion medicine. Relevant literature was found through PubMed. The reference lists of selected articles identified further sources. Conclusions: Blood donations by emigrants or travelers f…

Leishmaniasis and Biologic Therapies for Rheumatologic Diseases

2010

In his article in Seminars in Arthritis and Rheumatism,Furst (1) provides an accurate analysis of the infec-tions that are related to the use of biologic therapiesfor rheumatoid arthritis. We would like to addLeishma-niaspp to the list of the infectious agents that can causedisease during the course of biologic therapies.

Trends in the Epidemiology of Leishmaniasis in the City of Barcelona (1996–2019)

2021

Background: Leishmaniasis is a neglected zoonosis produced by 20 different flagellated parasites of the Leishmania genus, a protozoan transmitted to humans and other vertebrates by the bite of dipteran insects of the Phlebotominae subfamily. It is endemic in Mediterranean countries and the number of cases is expected to increase due to climate change and migration. Prioritizing public health interventions for prevention and control is essential. The objective was to characterize the epidemiology and temporal trends in the incidence of human leishmaniasis in the city of Barcelona, between the years 1996 and 2019. Methods: A population-based, analytical observational study among residents in …

Bibliometric analysis of leishmaniasis research in Medline (1945-2010)

2012

Background Publications are often used as a measure of success of research work. Leishmaniasis is considered endemic in 98 countries, most of which are developing. This article describes a bibliometric review of the literature on leishmaniasis research indexed in PubMed during a 66-year period. Methods Medline was used via the PubMed online service of the US National Library of Medicine. The search strategy was Leishmania [MeSH] or leishmaniasis [MeSH] from 1 January 1945 until 31 December 2010. Neither language nor document type restrictions were employed. Results A total of 20,780 references were retrieved. The number of publications increased steadily over time, with 3,380 publications f…

Behavioural treatment of improper eating by an institutionalised woman with profound intellectual disability—description of a successful intervention

2002

Intensive 11-day behavioural training of an institutionalised woman with profound intellectual disability was used to teach proper eating by reducing her eating errors. The methods used included an increased number of learning opportunities, graduated guidance, the use of social reinforcement, and mild punishment through simple correction of eating errors. The treatment was faded into a maintenance phase. After the intensive training phase, the participant ceased to eat with her fingers from a plate, and her eating changed to a more tidy habit. She was also released from having her hand tied during the meals. The results were maintained during an informal follow-up 4 years later.

Leishmaniasis among organ transplant recipients.

2008

Leishmaniasis is a rarely reported disease among transplant recipients; however, the number of published cases has quadrupled since the beginning of the 1990s. Most cases have been observed in patients living in countries of the Mediterranean basin. Leishmaniasis is most commonly associated with kidney transplantation (77%), and cases are also recorded among patients undergoing liver, heart, lung, pancreas, and bone marrow transplantation. Visceral leishmaniasis (VL) is the most frequently observed clinical presentation, followed by mucosal leishmaniasis and more rarely cutaneous leishmaniasis. Transplant recipients with VL develop the classic clinical form of the disease, which is a febril…

A Role for Leukocyte-Derived IL-1RA in DC Homeostasis Revealed by Increased Susceptibility of IL-1RA-Deficient Mice to Cutaneous Leishmaniasis

2011

Dendritic cell (DC)-derived IL-1α/β plays a critical role in the induction of T helper type 1 (Th1)-dependent immunity against Leishmania . DCs from susceptible BALB/c mice produce less IL-1α/β when compared with resistant C57BL/6 mice, contributing to aberrant Th2 development and ultimate death of infected mice. We have extended our studies of the role of IL-1 in leishmaniasis using IL-1RA -/- BALB/c mice that are characterized by upregulated IL-1 receptor signaling. Unexpectedly, infection of IL-1RA -/- mice led to significantly worsened disease outcome with larger lesions, dramatically higher parasite burdens, and decreased IFN-γ production by antigen-specific T cells. We determined that…

Ex vivoevidence for PGE2and LTB4involvement in cutaneous leishmaniasis: relation with infection status and cytokine production

1996

SUMMARYEx vivoculture of spleen cells from BALB/c mice infected with 2 × 106Leishmania major(L.major) promastigotes were cultured with ConcanavalinA (ConA) or leishmanial antigen (L. Ag) and tested for prostaglandin E2(PGE2) and for leukotriene B4(LTB4), in order to study their involvement in the evolution of cutaneous leishmaniasis and the connexion with lymphokine-mediated responses. The data were compared with those obtained in BALB/c mice protected againstL. majorby sublethal irradiation (550 rad; cured mice). In the unprotected BALB/c mice the levels of PGE2that were responsible for the depression of interferon-γ (IFN-γ) and tumour necrosis factor-α (TNFα) Th1-associated cytokines and …
