Raltegravir Inclusion Decreases CD4 T-Cells Intra-Cellular Viral Load and Increases CD4 and CD28 Positive T-Cells in Selected HIV Patients.

Raltegravir (RLT) prevents the integration of HIV DNA in the nucleus, but published studies remain controversial, suggesting that it does not decrease proviral DNA. However, there are only a few studies focused on virus-targeted cells. We aimed our study on the impact of RLT inclusion on total intra-cellular viral DNA (TID) in cellular subsets and immune effects in patients with newly acquired undetectable plasmatic viral load (UVL).

Antiretroviral Regimens and CD4/CD8 Ratio Normalization in HIV-Infected Patients during the Initial Year of Treatment: A Cohort Study.

Background: As CD4/CD8 ratio inversion has been associated with non-AIDS morbidity and mortality, predictors of ratio normalization after cART need to be studied. Here, we aimed to investigate the association of antiretroviral regimens with CD4/CD8 ratio normalization within an observational cohort.

Methods: We selected, from a French cohort at the Nice University Hospital, HIV-1 positive treatment-naive patients who initiated cART between 2000 and 2011 with a CD4/CD8 ratio <1.

Virological response and resistance mutations to NS3/4A inhibitors in hepatitis C virus-human immunodeficiency virus coinfection.

Aim: To evaluate virological response to telaprevir or boceprevir in combination with pegylated interferon and ribavirin and resistance mutations to NS3/4A inhibitors in hepatitis C virus-human immunodeficiency virus (HCV-HIV) coinfected patients in a real life setting.

Methods: Patients with HCV genotype 1-HIV coinfection followed in Nice University Hospital internal medicine and infectious diseases departments who initiated treatment including pegylated interferon and ribavirin (PegIFN/RBV) + telaprevir or boceprevir, according to standard treatment protocols, between August 2011 and October 2013 entered this observational study. Patient data were extracted from an electronic database (Nadis(®)).

Severe pneumonia during primary infection with an atypical strain of Toxoplasma gondii in an immunocompetent young man.

We report a case of severe acute primary pulmonary toxoplasmosis in an immunocompetent young man living in Nice (Southern France). The Toxoplasma DNA extracted from the broncho-alveolar lavage fluid allowed a genetic characterization of the responsible strain which displayed an atypical genotype of Toxoplasma gondii. This unusual genetic composition of the parasite may have influenced, among other factors, the severity of the disease.

[Lemierre's syndrome: a report of six cases].

Objective: Lemierre's syndrome is a rare but severe condition combining pyrexia, cervical pain and pulmonary signs following a pharyngeal infection, usually tonsillitis. This infectious disease is still present in our country despite wide use of antibiotic therapy in pharyngeal infections.

Methods: In a retrospective study conducted between 1995 and 2000 in two departments (infectious diseases and critical care unit) of Nice university hospital (Nice, France), we collected and analysed six cases of Lemierre's syndrome.
