Change in the hepatic profile of hepatitis C virus genotype 4-infected patients with compensated cirrhosis receiving ombitasvir, paritaprevir, and ritonavir plus ribavirin: A subanalysis of the AGATE-II study.

In AGATE-II, treatment with ombitasvir coformulated with paritaprevir/ritonavir plus ribavirin (RBV) in Egyptians infected with hepatitis C virus genotype 4 resulted in high rates of sustained virologic response at post-treatment week 12. This subanalysis examined the effects of treatment in AGATE-II on liver biomarkers in patients with compensated cirrhosis. AGATE-II was a phase 3, open-label, partly randomized trial of ombitasvir/paritaprevir/ritonavir with weight-based RBV daily once in treatment-naive or treatment-experienced patients.

Ombitasvir, paritaprevir, and ritonavir plus ribavirin for chronic hepatitis C virus genotype 4 infection in Egyptian patients with or without compensated cirrhosis (AGATE-II): a multicentre, phase 3, partly randomised open-label trial.

Background: In Egypt, chronic hepatitis C virus (HCV) infection occurs in around 10% of the population (about 8 million individuals), and is a leading cause of liver cirrhosis, hepatocellular carcinoma, and mortality. Although HCV genotype 4 constitutes about 20% of HCV infections worldwide, the prevalence in Egypt is more than 90%. We assessed the efficacy and safety of the two direct-acting antiviral drugs ombitasvir, an NS5A inhibitor, and paritaprevir, an NS3/4A protease inhibitor dosed with ritonavir, plus ribavirin in treatment of chronic HCV infection in Egypt.

Ombitasvir, paritaprevir, and ritonavir plus ribavirin in adults with hepatitis C virus genotype 4 infection and cirrhosis (AGATE-I): a multicentre, phase 3, randomised open-label trial.

Background: Hepatitis C virus (HCV) genotype 4 infection is most commonly reported in sub-Saharan Africa and the Middle East; however, prevalence is increasing worldwide through immigration. HCV genotype 4 accounts for 20% of all infections, but clinical trial data for treatment remain limited. We assessed the combination of two direct-acting antivirals, ombitasvir (NS5A inhibitor) and paritaprevir (NS3/4A protease inhibitor; co-dosed with ritonavir) plus ribavirin in patients with HCV genotype 4 infection and compensated cirrhosis.

Loss of bone mineral density after antiretroviral therapy initiation, independent of antiretroviral regimen.

Background: Decreased bone mineral density (BMD) has been described in HIV-infected patients initiating antiretroviral therapy (ART), but the contributions of ART and immunologic and/or virologic factors remain unclear.

Methods: We compared total BMD changes over 96 weeks in 106 ART-naive HIV-infected subjects who were randomized to receive efavirenz (EFV) + zidovudine/lamivudine (n = 32) or lopinavir/ritonavir (LPV/r) + zidovudine/lamivudine induction (n = 74) for 24-48 weeks followed by LPV/r monotherapy. We also sought to identify factors associated with BMD loss, including markers of systemic inflammation [soluble tumor necrosis factor-alpha receptors (sTNFR I and II)].

Successful treatment with atazanavir and lopinavir/ritonavir combination therapy in protease inhibitor-susceptible and protease inhibitor-resistant HIV-infected patients.

The combination of atazanavir (ATV) plus lopinavir/ritonavir (LPV/r) has been used in practice. However, clinical data supporting its use are limited. The objective of this study was to evaluate the efficacy and tolerability of regimens with ATV + LPV/r in protease inhibitor (PI)-susceptible and PI-resistant patients.

Antiretroviral therapy and the prevalence of osteopenia and osteoporosis: a meta-analytic review.

Introduction: Prevalence estimates of osteopenia and osteoporosis (reduced bone mineral density; BMD) in HIV-infected patients and the role of antiretroviral therapy (ART) varies in the literature.

Methods: We conducted a meta-analytical review of cross-sectional studies published in English to determine the pooled odds ratios (OR) of reduced BMD and osteoporosis in the following groups: HIV-positive versus HIV-negative; ART-treated versus ART-naive; protease inhibitor (PI)-treated versus PI-untreated. We searched the MEDLINE, PubMed, and EMBASE databases for eligible references between January 1966 and November 2005.

Bone disorders associated with the human immunodeficiency virus: pathogenesis and management.

Bone disorders such as osteopenia, osteoporosis, and osteonecrosis have been reported in patients infected with the human immunodeficiency virus (HIV), but the etiology and mechanism of these disorders are unknown. The prevalence estimates vary widely among studies and may be influenced by the presence or absence of antiretroviral therapy and lipodystrophy, severity of HIV disease, and overlapping bone loss risk factors. Addressing potential underlying bone disease risk factors (e.

Adefovir dipivoxil: a new antiviral agent for the treatment of hepatitis B virus infection.

Background: Hepatitis B virus (HBV) infection is a major problem worldwide and an important cause of chronic liver disease and cirrhosis. Currently available treatments include interferon alfa-2b, lamivudine, and adefovir dipivoxil. Adefovir dipivoxil is an acyclic nucleotide analogue that was developed in part to improve on the limitations of earlier therapies.

Management of anemia of chronic disease in patients with the human immunodeficiency virus.

Anemia is the most frequently encountered hematologic complication in human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome. The prevalence estimates vary widely with the severity of HIV disease. Data suggest that treatment with highly active antiretroviral therapy may have a positive impact on reducing the prevalence of anemia of chronic disease in patients infected with HIV.

Practical psychopharmacology in HIV-1 and acquired immunodeficiency syndrome.

HIV-1 infection poses a challenge for psychiatrists of the medically ill. Many factors concerning the care of HIV-1-infected patients need to be considered when prescribing psychotropics. These include careful diagnosis, taking into account medical disorders associated with HIV-1 that can present with psychiatric symptoms, as well as medications that HIV-1 patients may be taking that can cause a variety of neuropsychiatric side effects.
