Switching to nevirapine-based HAART in virologically-suppressed patients: influence of a longer twice-daily induction period on once-a-day dosing

We are conducting a multicenter, randomized, controlled, prospective, open trial to evaluate both the efficacy and toxicity of nevirapine (NVP) (given twice [BID] or once daily [QD]) in virologically-suppressed patients on a PIbased HAART. NVP BID dosing is maintained for 2 months after the switch in both groups

Once-a-Day (QD) <i>vs</i> Twice-Daily (BID) Nevirapine as simplification in PITreated patients after 2 mos. of BID induction

To assess the efficacy and the tolerability of once-daily (QD) versus twice-daily (BID) nevirapine (NVP)-based highly active antiretroviral therapy (HAART) in virologically suppressed, HIV-positive patients switched from protease inhibitor (PI)-based HAART. Eligible patients were enrolled in the multicenter trial if HIV RNA levels were &lt; 50 copies/mL for ≥6 months prior. Patients were switched from a PI to NVP 200 mg BID for 2 months, and then randomized to continue with that regimen (group A) or NVP 400 mg QD (group B) for a further 10 months. Virological efficacy (primary endpoint) and tolerability/toxicity were evaluated according to an intention-to-treat analysis. A total of 126 patients (63 per group) were enrolled. Withdrawals from the study (any reason) numbered 15 in group A and 14 in B, virological failures numbered 5 and 2, respectively, and there were 4 cases of adverse events in each group (all p = NS). Mean alanine aminotransaminase (ALT) and gamma-glutamyl transpeptidase (γ-GT) level increases were significant for the whole cohort (33.2±22.9 to 43.3±29.1, p &lt; 0.001; 57.3±72 to 109±131 U/L, p &lt; 0.0002, respectively), but there were no differences between the two groups. Apparently, no significant differences between the QD and BID NVP groups were found, in terms of virological failures or tolerability/toxicity. The switch to NVP may be safely pursued with a QD schedule

Epidemiological characteristics of bloodstream infections in patients with different degrees of liver disease

Observational retrospective study to evaluate the etiology, the outcome and the risk factors of bloodstream infections (BSIs) in patients with liver disease. One hundred and forty-eight BSIs were diagnosed (infection rate: 0.60 per 100 days of hospital stay), 62 BSIs (41.9 %) were associated with Gram-positive bacteria (infection rate: 0.25 per 100 days of hospital stay) and 80 (54.4 %) with Gram-negative bacteria (infection rate: 0.32 per 100 days of hospital stay). Admission-associated mortality was higher in patients with BSI than in those without BSI (20.6 versus 5.0 %, p < 0.001). Patients with cirrhosis had an increased risk to develop a BSI compared with patients with chronic hepatitis, specifically for Gram-positive (and Staphylococcus spp)-related BSI
