Does GSS still maintain relevance on HAART outcome after the introduction of newest active antiretroviral drugs? 48 weeks results.

Background: Since recent observations demonstrated that extended resistance to protease inhibitors, nucleosidic and non - nucleosidic retrotranscriptase inhibitors (PI, NRTI, NNRTI) is a marker of disease progression and death, it is a matter of the greatest importance that experienced human immunodeficiency virus (HIV) - infected patients with limited therapeutic options receive a suppressive therapy pending the availability of at least two new antiretroviral drugs. Aim of the present study is to evaluate if the GSS score, calculated by analyzing the resistance to historical antiretroviral drugs and drug classes, is still relevant since several new potent drugs and drug classes entered the current clinical use.

Methods: Taking into account patients without suppression of HIV replication for ≥ 6 months from October 2008 and October 2009, we analyzed viroimmunological and resistance data of 38 outpatients starting their last antiretroviral regimen including at least one of the following: maraviroc, enfuvirtide, raltegravir, etravirine, darunavir/ritonavir or tipranavir/ritonavir.

Noncirrhotic portal hypertension in HIV-infected patients: a case control evaluation and review of the literature.

Idiopathic noncirrhotic portal hypertension (NCPH) is an infrequent but possibly underestimated cryptogenetic liver disease recently described in small series of HIV-infected patients. The exposure to antiretroviral drugs, a direct role of HIV itself, microbial translocation from the gut, or a thrombophilic propensity have been suggested as possible pathogenic mechanisms. In this case control study, we describe 11 HIV-infected patients with idiopathic NCPH and compare the activity of protein C and S, and soluble CD14 levels (a surrogate marker of the translocation of intestinal bacterial products) with 10 age- and gender-matched HIV-infected controls with no liver disease.

Enterococcus gallinarum endocarditis in a diabetic patient.

Recent studies pointed out the increasing rate of infective endocarditis (IE) in diabetic patients. As diabetes mellitus (DM) prevalence is expected to increase in the coming years, infective endocarditis could be more frequently reported in these patients. We here describe a rare case of Enterococcus gallinarum endocarditis developing on normal native heart valve in an elderly diabetic woman.

Comparability of echographic and tomographic assessments of body fat changes related to the HIV associated adipose redistribution syndrome (HARS) in antiretroviral treated patients.

To assess the comparability of ultrasonographic (US) subcutaneous fat thickness (SFT) measurements in comparison with computed tomography (CT) at reference points (RPs) representative of HIV related adipose redistribution syndrome (HARS) in patients treated with antiretrovirals. US and CT measurements were compared in nine patients with clinical reports of HARS. We obtained the best resolution of facial (at deepest point of Bichat pad), brachial (in the dorsal face of arm) and crural SFT (at mid thigh) by means of minimal transducer pressures avoiding potential biases such as stand off pads pressure on the skin and artefacts due to too abundant quantity of gel.

Abacavir hypersensitivity reaction after switching from the twice-daily to the once-daily formulation.

A 36-year-old man with HIV infection developed a reaction compatible with an abacavir hypersensitivity reaction after switching from the twice-daily to the once-daily formulation. The switch was determined by a more convenient intake. The patient was treated with abacavir twice-daily plus lamivudine and efavirenz for more than 5 years with no side effects.
