OBJECTIVE To determine the association of delayed acyclovir therapy with death among neonates with herpes simplex virus (HSV) infection. METHODS A multicenter, retrospective, cohort study was conducted between January 1, 2003, and December 31, 2009, with 1086 neonates (age: ≤28 days) with HSV infection from 41 tertiary care children's hospitals. Early acyclovir therapy was defined as initiati...

OBJECTIVE to determine the role of digital photoplethysmography (D-PPG) in the diagnosis of deep-vein thrombosis (DVT), in comparison to the "gold standard" of either contrast ascending venography (ACV) or colour-flow duplex imaging (CFDI). METHOD prospective study of 100 hospital inpatients (103 legs) referred to the X-ray department for ACV or CFDI with clinically suspected lower limb DVT i...

We have examined the susceptibility to acyclovir and frequency of acyclovir-resistant viruses in herpes simplex virus type (HSV) 2 clones isolated directly from genital lesions of 11 patients who had taken suppressive therapy (200 mg/day) for 1-9 years and 15 patients naive to acyclovir. Suppressive therapy significantly reduced the incidence of recurrence and the severity of the skin lesions. ...

Rat pheochromocytoma (PC12) cells differentiated with nerve growth factor (Nd-PC12) were used to investigate the establishment of a non-productive herpes simplex virus type 1 (HSV-1) infection that is reversible. The results of this work are as follows: (i) Nd-PC12 cultures could be maintained as long term (>7 weeks) non-dividing cultures only when plated on collagen-coated dishes in the absenc...

acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. acyclovir triphosphate inhibits viral dna-polymerase terminating the chain and...

Chemical and enzymatic procedures have been employed for the preparation of various phosphorylated derivatives of the acyclonucleoside 9-(1,3-dihydroxy-2-propoxymethyl)adenine, an analogue of the active antiviral agent 9-(1,3-dihydroxy-2-propoxymethyl)guanine (DHPG). In combination with the previously reported 2',3'-seco nucleosides and their phosphates and cyclic phosphates (Stolarski et al., ...

BACKGROUND Acyclovir is acyclic guanosine derivative. Benzylpenicillin (PCG) is a β-lactam antibiotic. The purpose of this study was to investigate the pharmacokinetic drug-drug interaction (DDI) between PCG and acyclovir. METHOD When acyclovir and PCG were co-administered, plasma concentration of acyclovir, urinary excretion of acyclovir in vivo, uptake of acyclovir in kidney slices and upta...

BACKGROUND Traditionally, patients have been considered incapable of evaluating the quality of care they receive, leading to their minimal involvement. OBJECTIVE To develop the Patient's Assessment of Quality Scale--Acute Care Version (PAQS-ACV) to provide a mechanism through which patients can evaluate meaningfully the nursing care they receive. METHODS Developed from qualitative interview...

Herpes simplex virus type 1 (HSV-1) is part of the alpha subfamily human herpesviruses. Several antiviral medications can be prescribed for treating HSV-1 which usually first line agents such as acyclovir (ACV). But there are several cases that have been reported on ACV resistance to HSV, thus, researchers tend develop agent from plants extract. Syzygium polyanthum one has traditionally used a ...

Abstract Herpes simplex virus is among the most prevalent sexually transmitted infections. Acyclovir a potent, selective inhibitor of herpes viruses and it indicated for treatment management recurrent cold sores on lips face, genital herpes, other diseases. The problem oral bioavailability acyclovir limited because low permeability across gastrointestinal membrane. use nanoparticles pseudoboehm...
