Unlabelled: Two cases of visceral leishmaniasis (VL) in immunocompetent patients have been described. Both patients lived in endemicic areas for leishmaniasis in the south of Italy, tested positive for anti-Leishmania antibodies. A definitive diagnosis of VL was delayed by false negative microscopic examinations. Both patients were treated successfully with liposomal amphotericin B.
Conclusions: Immuno Fluorescent Assay (IFA) performed as an available test. It helped to pursue the correct diagnosis and therapy. Microscopy is reported to be highly sensitive and specific in the diagnosis of VL, nevertheless it may yield false negative results when examined in laboratories without good expertness.

In Brazil, Visceral Leishmaniases is caused by Leishmania infantum, and domestic dogs are the main reservoirs in its urban transmission cycle. As an alternative to euthanizing dogs, miltefosine has been used to treat canine visceral leishmaniasis since 2016. In this study, we have assessed the efficacy of miltefosine for treating canine visceral leishmaniasis in a new endemic area through follow-up of naturally infected dogs was evaluated.

Understanding the development and maintenance of immunological memory is important for efforts to eliminate parasitic diseases like leishmaniasis. Leishmaniasis encompasses a range of pathologies, resulting from infection with protozoan parasites belonging to the subgenera and of the genus A striking feature of these infections is that natural or drug-mediated cure of infection generally confers life-long protection against disease. The generation of protective T cell responses are necessary to control infections.

Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical entity characterized by fever, constitutional symptoms, and hepatosplenomegaly associated with the presence of hemophagocytosis in the bone marrow and other organs. Visceral leishmaniasis (VL) is a severe zoonotic disease hypoendemic in Portugal, particularly in the Alto Douro region. We report the case of a 21-year-old female patient with a recent diagnosis of human immunodeficiency virus (HIV) infection, stage C3, in the context of severe pneumonia, who presented to the emergency department with fever, erythematous rash on the upper limbs and trunk, choluria and jaundice, one week after starting antiretroviral therapy (ART).

Introduction: Ensuring accuracy in the diagnosis of leishmaniasis is crucial due to the myriad of potential differential diagnoses. Given the inherent limitations of serological techniques, real-time polymerase chain reaction (qPCR) emerges as a superior alternative. Furthermore, parasitological methods, conventionally regarded as the gold standard owing to their high specificity, encounter challenges concerning sensitivity and invasiveness for patients.

Parasites have coexisted with humans throughout history, forming either symbiotic relationships or causing significant morbidity and mortality. The liver is particularly vulnerable to parasitic infections, which can reside in, pass through, or be transported to the liver, leading to severe damage. This editorial explores various parasites that infect the liver, their clinical implications, and diagnostic considerations, as discussed in the article "Parasites of the liver: A global problem?".
