In 2013, an estimated 1.5 million HIV-positive pregnant women gave birth, with 240,000 children worldwide acquiring HIV. More than 90% of new pediatric infections occurred in Sub-Saharan Africa.

He was the first Italian case and was successfully cured in 38 days. The staff responsible for communication had a critical role ensuring that this challenging mission went smoothly.

Some of these have been medically evacuated to hospitals in Europe and the USA. These clinical experiences provide unique insights into the course of Ebola virus disease under optimized condition within high level isolation units.

We assessed the probability of patients reaching a CD4/CD8 ratio of 1 or more after the start of ART and its association with the onset of non-AIDS-defining events and death.
Methods: We did an analysis of the ICONA cohort, which recruited treatment-naive patients with HIV in Italy.
Background: Increased evidence of relevant HIV-1 epidemic transmission in European countries is being reported, with an increased circulation of non-B-subtypes. Here, we present two recent HIV-1 non-B transmission clusters characterized by NNRTI-related amino-acidic mutations among newly diagnosed HIV-1 infected men, living in Rome (Central-Italy).
Methods: Pol and V3 sequences were available at the time of diagnosis for all individuals.
Intravenous artesunate improves survival in severe malaria, but clinical trial data from nonendemic countries are scarce. The TropNet severe malaria database was analyzed to compare outcomes of artesunate vs quinine treatment. Artesunate reduced parasite clearance time and duration of intensive care unit and hospital treatment in European patients with imported severe malaria.

The sequence, clustering in clade 3 of the Sierra Leone sequences, was analyzed with respect to mutations possibly affecting diagnostic and therapeutic targets as well as virulence.

We describe the imaging protocol used by National Institute for Infectious Diseases Lazzaro Spallanzani to acquire chest radiographs in patients with Ebola virus disease.
Key Points: • Nosocomial transmission to healthcare workers can be prevented using protective equipment.
Objectives: Integrase drug resistance monitoring deserves attention because of the increasing number of patients being treated with integrase strand-transfer inhibitors. Therefore, we evaluated the integrase genotyping success rate at low-level viraemia (LLV, 51-1000 copies/mL) and resistance in raltegravir-failing patients.
Methods: An integrase genotypic resistance test (GRT) was performed on 1734 HIV-1 samples collected during 2006-13.
Introduction: Central nervous system (CNS) penetration-effectiveness (CPE) rank was proposed in 2008 as an estimate of penetration of ARV regimen into the CNS, and validated as predictor of CSF HIV-1 replication. RESULTS on predictive role of CPE on neurocognitive and clinical outcome were conflicting.
Materials And Methods: Retrospective, cross-sectional analysis of neurocognitive profile in HIV-infected cART-treated patients.
Coccidioidomycosis is a fungal infection caused by the Coccidioides species, which is endemic in the deserts of the southwestern region of the United States, northern Mexico, and in some areas of Central and South America. We describe a case of pulmonary coccidioidomycosis in a 49-year-old Italian man who came to our hospital with fever and joint and muscle pain 10 days after his return to Italy from Venezuela. Computer Tomography revealed multiple bilateral pulmonary nodules with mediastinal lymphadenopathy.

Moreover, prolonged use of protease inhibitors (PIs) causes profound changes in lipid metabolism with an increased risk of cardiovascular diseases. P-glycoprotein (P-gp) is expressed on many cell types, playing an important role in the efflux of drugs including PIs, limiting their intracellular concentration.

Methods: The genotyping success rate was evaluated in 12 828 human immunodeficiency virus type 1 (HIV-1) plasma samples with viremia >50 copies/mL, tested using the commercial ViroSeq HIV-1 Genotyping System or a homemade system. Phylogenetic analysis was performed to test the reliability and reproducibility of the GRT at low-level viremia (LLV).
Purpose: Topical negative pressure (TNP) has become a common treatment of infected wounds. A systematic review and meta-analysis was performed to investigate TNP efficacy compared to conventional therapy in the treatment of deep surgical site infections (SSIs), particularly post-sternotomy infections.
Methods: MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were searched for randomized clinical trials (RCTs) and observational studies comparing TNP to conventional treatment in deep SSIs published up to February 2012.
Background: HIV resistance affects virological response to therapy and efficacy of prophylaxis in mother-to-child-transmission. The study aims to assess the prevalence of HIV primary resistance in pregnant women naïve to antiretrovirals.
Methods: Cross sectional baseline analysis of a cohort of HIV + pregnant women (HPW) enrolled in the study entitled Antiretroviral Management of Antenatal and Natal HIV Infection (AMANI, peace in Kiswahili language).
Introduction: Diagnosing tuberculosis in low-resource settings mostly relies on sputum smear microscopy. Improvement through capacity building is a priority. This project aimed to strengthen tuberculosis diagnosis at an intermediate level laboratory.
View Article and Find Full Text PDFBackground: It is unclear whether lack of immunological response despite viral suppression and relatively preserved CD4 T-cell count is associated with increased risk of AIDS or severe non-AIDS events.
Methods: Patients initiating first combination antiretroviral therapy (cART) were studied from first viral load 80 copies/ml or less up to AIDS, serious non-AIDS events (malignancies, severe infections, acute kidney injury, cardiovascular events, liver decompensation) or death. Follow-up was right censored if viral load was more than 500.
It has been shown that P-glycoprotein (P-gp) can greatly affect the cell uptake of antiretroviral drugs, thus hampering their access to HIV-1 replication sites. Lymphocytes are important sites of replication of HIV and target of other drugs, modification on these cells of P-gp could have an effect on pharmacokinetic of antiretrovirals and drug substrates. Blood samples from 16 healthy volunteers were used to determine the expression of P-gp on total, T and T helper lymphocytes after exposure to darunavir, a second generation protease inhibitor, and raltegravir, the first approved integrase inhibitor.

Methods: Three hundred HIV-1-infected patients failing a first-line NNRTI-containing regimen (nevirapine, n = 148; efavirenz, n = 152) were included in the analysis. Virological failure was defined as viraemia ≥ 400 HIV-1 RNA copies/mL for the first time at least 6 months after starting the NNRTI-based regimen.
Background: In recent years, Nocardia farcinica has been reported to be an increasingly frequent cause of localized and disseminated infections in the immunocompromised patient. However, recent literature is limited. We report a case of left thigh phlegmon caused by N.

In this paper, we describe the occurrence of haemolysis after oral artemether-lumefantrine treatment. To the best of our knowledge, this is the second reported case of a patient affected by severe falciparum malaria with haemolytic anaemia that is likely associated with oral artemether-lumefantrine treatment.
