[Perception of risk of HIV infection and knowledge about the use of antiretrovirals in prevention].

Introduction: Combined prevention (CP) is considered the key strategy against the HIV epidemic. The objective of the study was to evaluate the perception of risk of HIV infection and the knowledge about the use of antiretrovirals (ARV) for prevention, among patients who attend a Sexually Transmitted Infections (STI) clinic.

Methods: A survey on personal data and perception of risk of HIV infection, knowledge about post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), was administered to patients at the time of applying doses of penicillin for the treatment of syphilis, or when taking a blood sample for STI diagnosis, between May and December, 2022.

[Hepatitis C treatment in the surrounding area of Buenos Aires].

Hepatitis C virus (HCV) infection is currently the main blood-borne viral infection. One of the main obstacles to achieving its control in Argentina is related to difficulties in accessing the diagnosis and timely treatment of infected people. We carried out this study with the aim of characterizing the HCV-infected patients who started treatment with direct-acting antivirals (DAAs) and to describe the experience related to treatment.

HIV and Chagas Disease Coinfection, a Tractable Disease?

We present 2 patients born in Argentina who were newly diagnosed with advanced HIV disease and Chagas disease reactivation with central nervous system involvement. The patients received concurrent benznidazole treatment and antiretroviral therapy, showing good response. Improvement in morbidity and mortality due to early treatment makes this treatment appropriate for coinfected patients.

[Pregnancy and postpartum control in HIV infected women].

Pregnancy and postpartum control in HIV infected women. We present data from a retrospective observational descriptive study with the objective of evaluating characteristics of HIV-infected pregnant women, analyze the level of control of pregnancy and assess adherence to treatment and loss of follow up after delivery. We analyzed reported data of 104 pregnancies, 32.

[Factors associated to late clinical stage at the initiation of antiretroviral therapy].

In order to evaluate the frequency of a late clinical stage in HIV infected patients at onset of antiretroviral therapy (LART) and to identify possible associated factors, we performed a retrospective analysis of data reported in two prospective cohorts of HIV infected patients who started antiretroviral therapy for the first time between 2005 and 2009. Medical records of 265 patients -123 women (46.6%) and 141 men, median age 37.
