BACKGROUND Physicians often fail to use lung-protective ventilation (LPV) in patients with acute lung injury. OBJECTIVE To use physician documentation to identify why physicians did not initiate or continue LPV in patients with acute lung injury. METHODS This was a retrospective cohort study in a university hospital. The study period was September 2000 through November 2002. In our primary ...

Introduction: The use of lopinavir/ritonavir (LPV/r) has decreased morbidity and mortality due to human immunodeficiency virus (HIV); however its use could be impaired by hepatotoxicity. Therefore, this study was designed to investigate the effects of melatonin (MT) and alpha lipoic acid (ALA) on LPV/r-induced hepatotoxicity in male albino rats. Methods: Rats were divided into groups and treate...

Monkey B-lymphotropic papovavirus (LPV) replicates only in B-lymphoblastoid cells, whereas the LPV mutant 76 (LPV-76) can grow in either B- or T-lymphoblastoid cells. The nucleotide sequence of the wild-type LPV PstI B segment was compared with that of LPV-76 PstI-B, within which the mutation responsible for the extended host range had been located. The VP-1 coding region of LPV-76 was found to...

BACKGROUND Despite widespread guidelines recommending the use of lung-protective ventilation (LPV) in patients with acute lung injury (ALI), many patients do not receive this lifesaving therapy. We sought to estimate the incremental clinical and economic outcomes associated with LPV and determined the maximum cost of a hypothetical intervention to improve adherence with LPV that remained cost-e...

Inhibition of the bile salt export pump (BSEP) can cause intracellular accumulation of bile acids and is a risk factor for drug-induced liver injury in humans. Antiretroviral protease inhibitors lopinavir (LPV) and ritonavir (RTV) are reported BSEP inhibitors. However, the consequences of LPV and RTV, alone and combined (LPV/r), on hepatocyte viability, bile acid transport, and endogenous bile ...

PURPOSE This study was aimed to develop a novel Histidine-Leucine-Lopinavir (His-Leu-LPV) dipeptide prodrug and evaluate its potential for circumvention of P-gp and MRP2-mediated efflux of lopinavir (LPV) indicated for HIV-1 infection. METHODS His-Leu-LPV was synthesized following esterification of hydroxyl group of LPV and was identified by (1)H NMR and LCMS/MS techniques. Aqueous solubility...

Monkey B-lymphotropic papovavirus (LPV) DNA present as free copies in LPV-transformed hamster embryo cells was molecularly cloned in Escherichia coli. Twenty-two of 24 cloned DNAs were 4.9 kilobases long and shorter than the wild-type LPV DNA (5.1 kilobases). The shorter DNA was nondefective and generated infectious virus (designated LPV-76) upon transfection of human B-lymphoblastoid BJA-B cel...

BACKGROUND Data on suppression of HIV replication in the CNS and on the subsequent risk of neurocognitive impairment using monotherapy with boosted protease inhibitors are limited. METHODS Ours was an exploratory cross-sectional study in patients on lopinavir/ritonavir-based monotherapy (LPV/r-MT) or standard triple therapy (LPV/r-ART) for at least 96 weeks who maintained a plasma viral load ...

INTRODUCTION Plasma trough concentrations of lopinavir (LPV) given as LPV/r 800/200 mg once daily (OD) are reduced in comparison with 400/100 mg twice daily (BID). While OD dosage of LPV/r is sufficient to achieve viral suppression in plasma, data about drug penetration and viral suppression in central nervous system (CNS) is needed, mainly if LPVr is used as maintenance monotherapy strategy in...

Introduction: This study evaluated the effects of pretreatments with melatonin (MT), and Alpha Lipoic acid (ALA) on lopinavir/ritonavir (LPV/r) -induced serum levels of creatinine (Cr), urea (U), uric acid (Ua) and kidney levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and catalase (CAT) in male albino rats. Effects of treatments with MT and ALA were also evaluate...
