A case of visceral leishmaniasis and pulmonary tuberculosis in a post-partum woman

2015

AbstractVisceral leishmaniasis due to Leishmania infantum is a vector-borne zoonotic disease transmitted by sand fly bites endemic in rural or periurban areas of the Mediterranean basin. Pregnancy is accompanied by changes in immune response, mainly a decrease in cellular immunity and a proportional increase in humoral immunity. These physiological events result in increased risk of infection by pathogens whose immunity is based on a T-helper 1 predominant response. We describe a case of visceral leishmaniasis and pulmonary tuberculosis diagnosed in a post-partum woman four days after delivery. The diagnosis of leishmaniasis should be considered in pregnant women with fever and haematologic…

Leishmaniasis in Norway Rats in Sewers, Barcelona, Spain.

2019

We detected Leishmania infantum in 98 Norway rats (Rattus norvegicus) trapped in parks and sewers of Barcelona, Spain. The 84 rats from the sewers showed a prevalence of 33.3% and up to 2,272 estimated parasites. These results, in the most abundant potential reservoir in cities, is of public health concern.

Visceral leishmaniasis: host-parasite interactions and clinical presentation in the immunocompetent and in the immunocompromised host.

2013

SummaryVisceral leishmaniases are vector-borne parasitic diseases caused by protozoa belonging to the genus Leishmania. The heterogeneity of clinical manifestations and epidemiological characteristics of the disease reflect the complex interplay between the infecting Leishmania species and the genetic and immunologic characteristics of the infected host. The clinical presentation of visceral leishmaniasis depends strictly on the immunocompetency of the host and ranges from asymptomatic to severe forms. Conditions of depression of the immune system, such as HIV infection or immunosuppressive treatments, impair the capability of the immune response to resolve the infection and allow reactivat…

Evolution of coauthorship networks: worldwide scientific production on leishmaniasis.

2013

Introduction Collaboration is one of the defining features of contemporary scientific research, and it is particularly important with regard to neglected diseases that primarily affect developing countries. Methods The present study has identified publications on leishmaniasis in the Medline database from 1945 to 2010, analyzing them according to bibliometric indicators and statistics from social network analysis. Examining aspects such as scientific production, diachronic evolution, and collaboration and configuration of the research groups in the field, we have considered the different types of Leishmania studied and the institutional affiliation and nationality of the authors. Results Se…

Pediatric visceral leishmaniasis in Western Sicily, Italy: a retrospective analysis of 111 cases

2002

The clinical and epidemiological characteristics of 111 consecutive cases of visceral leishmaniasis identified from 1980 to 2000 in a Sicilian pediatric hospital were analyzed retrospectively. The mean age of the patients was 1.7 years. All children were HIV negative, but 15% were severely malnourished. Fever and splenomegaly were present in all cases and hepatomegaly in 101 (90.1%) cases. Thrombocytopenia and anemia were both observed in 78 (70.2%) cases and leukopenia in 47 (42.3%) cases. A bone marrow aspirate was obtained in all cases; Leishmania amastigotes were detected in 89 (80.2%) cases. Initial treatment consisted of meglumine antimoniate in 99 (89.2%) patients and amphotericin B …

Third Case of Visceral Leishmaniasis in COVID-19: Mini Review Article.

2022

Background: In the currently ongoing coronavirus pandemic, coinfections with unrelated life-threatening febrile conditions may pose a particular challenge to clinicians. Leishmaniasis is a zoonosis that may present general symptoms, including fever, malaise, and arthralgia, rendering it indistinguishable from COVID-19. Methods: In this paper, we aim to draw attention to this issue and analyze the clinical characteristics of the coinfection SARS-CoV-2/Leishmania through a systematic review of the literature. We were motivated by the observation of the first case of visceral leishmaniasis and COVID-19 in a paediatric patient. Conclusion: Our case is a reminder for healthcare providers to cons…

Visceral leishmaniasis, hypertriglyceridemia and secondary hemophagocytic lymphohistiocytosis

2016

cytokines, an upregulation of adhesion molecules and MHC I and II molecules on mono/macrophages, and an expansion of inflammatory monocytes. This exaggerated inflammatory response is responsible for necrosis and organ failure and results in uncontrolled proliferation and phagocytic activity of histiocytes [2]. Hypertriglyceridemia (fasting, greater than or equal to 265 mg/100 ml) is one of the current diagnostic criteria for HLH [2]. Several studies link hypertriglyceridemia to inhibition of lipoprotein lipase (LPL) by tumor necrosis factor-α (TNF-α), and TNF-α is a powerful autocrine and paracrine regulator of adipose tissue [3]. Indeed, many different sources of intense and prolonged T-ly…

Compulsive Internet Use and Academic Procrastination: Significant Comparative, Correlative and Predicting Indicators in a Romanian Student Sample

2017

Abstract The purpose of this study was to investigate significant measures between indicators / factors associated to compulsive Internet use and academic procrastination behaviors, for a sample of students, from Romanian education institutions. Previous transcultural findings indicate that compulsive Internet use and procrastination behaviours, but in most cases investigated separately, can interfere, distract, delay and / or have a negative impact on academic work / achievement (completing reading assignments, homework, studying for exams / academic failure), task performance and quality of life (personal and social obligations). Romanian participants were asked on a voluntary basis and w…
