Introduction: Longitudinal data on the changes in kidney function and tubular abnormalities in case of tenofovir disoproxil fumarate (TDF) withdrawal or continuation are scarce.
Methods: Prospective study of 228 patients receiving TDF, with 3 sequential determinations of serum creatinine, estimated glomerular filtration rate (eGFR), phosphatemia, and different urinary parameters (protein, albumin, phosphaturia, uricosuria, and glycosuria). Changes were analyzed in patients who interrupted TDF as compared to those who continued the same regimen.
Introduction: The mechanisms underlying the effect of tenofovir disoproxil fumarate (TDF) on the decline of bone mineral density (BMD) have not been established, especially the effect of renal tubular dysfunction.
Methods: Longitudinal study of 90 patients with two successive dual X-ray absorptiometry scans after evaluation of serum and urinary parameters (proteinuria, albuminuria, phosphaturia, uricosuria, glycosuria, β-2-microglobulin, and retinol-binding protein).
Results: After a median of 38 months on TDF, osteopenia at spine and hip was observed in 49 and 48%, and osteoporosis in 9 and 2%, respectively.
Objectives: Patients receiving tenofovir, disoproxil, fumarate (TDF) had an increased prevalence of proximal renal tubular dysfunction (PRTD), but contributing factors and its clinical significance remain controversial.
Design And Methods: Cross-sectional evaluation of different urinary parameters (proteinuria, albuminuria, phosphaturia, uricosuria, glycosuria) in 200 HIV-infected patients receiving TDF, 26 following TDF discontinuation, and 22 never treated with TDF, included in a prospective cohort study. PRTD was defined as two or more tubular abnormalities.
Raltegravir and lamivudine have been part of highly active therapy regimens throughout the past years of antiretroviral therapy. A fixed-dose, single-tablet regimen comprising a non-poloxamer formulation of the integrase inhibitor raltegravir and the transcriptase inhibitor lamivudine (raltegravir/lamivudine; Dutrebis(®)) has been recently licensed for the treatment of HIV-1 infection. In several Phase I pharmacokinetic studies, one Dutrebis (150 mg lamivudine/300 mg raltegravir) fixed-dose combination tablet showed a higher bioavailability but comparable lamivudine and 400 mg raltegravir poloxamer exposures.

Methods: We compared the incidence rate (IR) and the time to develop a liver complication and death in 133 cirrhotic patients according to SVR or/and FR.
Results: Of 42 patients with SVR, 23 (55%) had FR, in comparison with only 14 of the 91 (15%) without SVR.
Background: There are few data on the best combination antiretroviral therapy in patients with HIV infection who need cancer chemotherapy because of drug-drug interactions and increased risk of toxic effects.
Methods: We evaluated the safety, efficacy and interactions of a raltegravir (RAL)-based regimen in 30 HIV-infected patients who received antineoplastic agents.
Results: A total of 17 patients had a non-AIDS-defining malignancy (7 with Hodgkin disease) and 13 had an HIV-related cancer (9 non-Hodgkin lymphoma, 2 Kaposi sarcoma and 2 anal cancer).
Novel combination antiretroviral regimens may be needed for selected HIV-infected patients with toxicity or resistance. We evaluated prospectively 25 virologically suppressed patients, largely pretreated (15.6 years on therapy) with antiretroviral drug toxicity (n=19) or interactions (n=9, mainly with chemotherapy against non-Hodgkin lymphoma or anti-HCV therapy), who switched to a dual therapy with etravirine (ETR) plus raltegravir (RAL).

The aim of this study was to assess the effect of an oral monthly dose of 16,000 IU calcidiol. We performed a longitudinal cohort study of 365 HIV-infected patients (24 % females) was with sequential determinations of 25OHD, serum parathyroid hormone (PTH), calcium, and alkaline phosphatase.

However, there are few data on the efficacy, safety and pharmacokinetics of this dual therapy, taking into account the effect of HCV co-infection or the possible induction of ETR in the drug metabolism of RAL.
Material And Methods: Cohort study of HIV patients initiating ETR plus RAL as dual therapy.
Introduction: Concomitant use of combination antiretroviral regimen (cART) and cancer chemotherapy is difficult due to complex interactions and increased toxicity. Raltegravir could be an adequate option through its favourable drug-drug interaction profile.
Methods: Prospective longitudinal study of HIV patients with cancer, AIDS related or not, undergoing chemotherapy.
Introduction: Etravirine has become an alternative in HIV/HCV coinfected patients because of safety and lack of interactions with anti-HCV drugs. The aim of this study was to establish the risk of liver toxicity in HIV/HCV coinfected patients receiving etravirine in the clinical setting, according to the degree of liver fibrosis and different accompanying drugs.
Material And Methods: Cohort study of 211 patients initiating etravirine as part of their antiretroviral regimen.
The usefulness of every antiretroviral drug in the clinical setting should be continuously evaluated, since registration studies may not adequately reflect real-world patient populations. Rilpivirine was developed in an effort to generate patient-tailored drugs with high convenience and minimal side effects. By now, rilpivirine is currently licensed for use with other antiretroviral agents, and as a single agent or a single-tablet regimen with tenofovir and emtricitabine , in antiretroviral-naive, HIV-1-infected adults with < 100,000 HIV-1 RNA copies/ml because of a higher rate of virological failure above this level.

Design: Longitudinal study which involved 265 HIV patients without DM, receiving first (n=71) and advanced lines of antiretroviral therapy (n=194).
Methods: Prevalence of IR according to clinical and anthropometric variables, including dual X-ray absorptiometry (DXA) scan evaluation.
