Our aim is to describe clinical and laboratory characteristics of HIV-associated Cryptococcal Meningitis (CM), in-hospital outcomes and analyze associations of these parameters with adverse outcomes.

Methods: Observational study of local cohort of HIV-associated cryptococcal meningitis in a high complexity tertiary urban hospital in Santiago, Chile.

We present the case of a 22-year-old patient with no morbid history who developed a brain abscess secondary to endocarditis due to Eikenella corrodens. The diagnosis was established by detecting the microorganism by universal polymerase chain reaction in fluid from the brain collection. Trans-esophageal echocardiogram study confirmed vegetations in the mitral valve.

In this prospective, multicentric, observational study, we describe the clinical characteristics and outcomes of people living with HIV (PLHIV) requiring hospitalization due to COVID-19 in Chile and compare them with Chilean general population admitted with SARS-CoV-2. Consecutive PLHIV admitted with COVID-19 in 23 hospitals, between 16 April and 23 June 2020, were included. Data of a temporally matched-hospitalized general population were used to compare demography, comorbidities, COVID-19 symptoms, and major outcomes.

He also presented with orthopnea, paroxysmal nocturnal dyspnea, and mild ankle swelling, but he showed no fever, wheezing, coughing, or sputum production. Outpatient laboratory studies, performed 1 week after symptom onset, revealed hypereosinophilia (4.

Antiretroviral therapy (ART) has shown to be an effective measure in decreasing HIV vertical transmission (VT). Nevertheless, it is not free from adverse effects in the newborn: risk of prematurity, low birth weight, metabolic disorders, among others. Despite the importance of the subject, there are few national data that analyze the problem.

We report a 43 years old HIV-1 infected male who developed a severe subacute neurological damage because of a progressive multifocal leukoencephalopathy confirmed by PCR for JC virus. The patient was treated with antiretroviral therapy in adequate doses for CNS penetration and mirtazapine, an antidepressant inhibitor of serotonin receptors. His evolution during one year follow up has been favorable in both, clinically and images.

Neurosyphilis follows a more aggressive and different clinical course in HIV-infected patients compared to patients with normal immunity. Two historical series of patients with a diagnosis of neurosyphilis between 1995 and 2008 were compared: they included a group of 15 patients with y and 28 patients without HIV infection. Probability of neurosyphilis in patients with positive serum VDRL was increased in patients infected with HIV compared to HIV negative patients (OR: 62.

Objective: To compare the performance of two tests for diagnosing latent tuberculosis (TB) infection in the HIV-positive population in Chile, in order to better identify the subjects who might benefit from TB chemoprophylaxis.

Design: This was a cross-sectional study among individuals attending three HIV outpatient clinics in Santiago, tested with a 2-TU purified protein derivative, QuantiFERON((R))-TB Gold 'in-tube' (QFT-G), and a chest X-ray.

Results: A total of 116 subjects were enrolled in the study, having a mean CD4 count of 393cells/microl (range 100-977).

Objective: The objective was to compare the safety and efficacy of intravenous labetalol and intravenous hydralazine for acutely lowering blood pressure in pregnancy.

Study Design: Two hundred women with severe hypertension in pregnancy were randomized to receive hydralazine (5 mg as a slow bolus dose given intravenously, and repeated every 20 min up to a maximum of five doses) or labetalol (20-mg intravenous bolus dose followed by 40 mg if not effective within 20 min, followed by 80 mg every 20 min up to a maximum dose of 300 mg). The primary end point was successful lowering of blood pressure and maternal hypotension.
