Abstract
The scintillating association between Leishmania and HIV has contributed exceptionally towards expansion of Visceral Leishmaniasis (VL) with Acquired Immunodeficiency Syndrome (AIDS). The co-infection poses a grievous threat to elimination of VL and containment of Human Immunodeficiency Virus (HIV). When coinfected, Leishmania and HIV complement each other's proliferation and survival by inducing immunesenescence, T cell fatigue and exhaustion. Antigen presentation is lost, co-stimulatory molecules are diminished whereas co-inhibitory molecules such as CTLA-4, TIGIT, LAG-3 etc. are upregulated to ensure a Th2-baised immune environment. As a consequence, Leishmania-HIV coinfection causes poor outcomes, inflates the spread of Leishmania parasites, enhances the severity of side-effects to drugs, as well as escalate the probability of treatment failure and mortality. What makes control extremely strenuous is that there are frequent episodes of VL relapse with no prognostic markers, no standard immunophenotype(s) and appearance of atypical clinical symptoms. Thus, a standard therapeutic regimen has been difficult to develop and treatment is majorly dependent upon a combination of liposomal Amphotericin B and Miltefosine, a therapy that is expensive and capable of causing drastic side-effects in recipients. As World Health Organization is committed to eliminate both VL and HIV in due course of future, the existing therapeutic interventions require advancements to grapple and overcome this hazardous co-infection. In this context, an overview of HIV-VL co-infection, immunopathology of HIV and Leishmania co-inhabitance, available therapeutic options and their limitations in the treatment of co-infection are discussed in-depth.

Evaluation of Proinflammatory Chemokines in HIV Patients with Asymptomatic Leishmania Infantum Infection. Trop Med Infect Dis 2023; 8:495. [PMID: 37999614 PMCID: PMC10675805 DOI: 10.3390/tropicalmed8110495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/21/2023] [Accepted: 09/21/2023] [Indexed: 11/25/2023] Open
Abstract
Asymptomatic Leishmania infantum, when associated with HIV, can become severe and potentially fatal. In this co-infection, the worst prognosis may be influenced by the host's immunological aspects, which are crucial in determining susceptibility. Chemokines play an important role in this process by influencing the cellular composition at affected sites and impacting the disease's outcome. Therefore, the aim of this study was to evaluate proinflammatory chemokines in HIV patients with the asymptomatic L. infantum infection. In this cross-sectional study, the levels of CCL2, CCL5, CXCL8, MIG, and IP-10 were measured in 160 serum samples from co-infected patients (n = 53), patients with HIV (n = 90), and negative controls (n = 17). Quantification was determined by flow cytometry. The obtained data were statistically analyzed using the Kruskal-Wallis test, followed by the Dunn's post-test and the Spearman's correlation coefficient. Significance was set at p < 0.05. The chemokines CCL2, CCL5, MIG, and IP-10 exhibited higher levels in the HIV group compared to co-infection. However, the elevated levels of all these chemokines and their increased connectivity in co-infected patients appear to be important in identifying proinflammatory immune responses associated with the asymptomatic condition. Furthermore, a weak negative correlation was observed between higher levels of CXCL8 and lower viral loads in co-infected patients.

Abstract
A zoonosis is an infectious disease that has jumped from a non-human animal to humans. Some zoonoses are very common in the Mediterranean area and endemic in specific regions, so they represent an important problem for public health. Human Immunodeficiency Virus (HIV) is a virus that has originated as a zoonosis and is now diffused globally, with the most significant numbers of infected people among the infectious diseases. Since the introduction of antiretroviral therapy (ART), the history for people living with HIV (PLWH) has changed drastically, and many diseases are now no different in epidemiology and prognosis as they are in not-HIV-infected people. Still, the underlying inflammatory state that is correlated with HIV and other alterations related to the infection itself can be a risk factor when infected with other bacteria, parasites or viruses. We reviewed the literature for infection by the most common Mediterranean zoonoses, such as Campylobacter, Salmonella, Brucella, Rickettsia, Borrelia, Listeria and Echinococcus, and a possible correlation with HIV. We included Monkeypox, since the outbreak of cases is becoming a concern lately. We found that HIV may be related with alterations of the microbiome, as for campylobacteriosis, and that there are some zoonoses with a significant prevalence in PLWH, as for salmonellosis.
