PK/PD-based adaptive tailoring of oseltamivir doses to treat within-host influenza viral infections.

Influenza A virus (IAV) is a latent global threat to human health. In view of the risk of pandemics, prophylactic and curative treatments are essential. Oseltamivir is a neuraminidase inhibitor efficiently supporting recovery from influenza infections. Current common clinical practice is a constant drug dose (75 or 150 mg) administered at regular time intervals twice a day. We aim to use quantitative systems pharmacology to propose an efficient adaptive drug scheduling. We combined the mathematical model ...

Acute Hepatitis C (AHC) infections, resolves spontaneously in 15-40% of patients. Factors favoring spontaneous viral clearance remain undefined. In this study, predictors of spontaneous viral clearance in symptomatic AHC patients were investigated. Epidemiological, clinical and virologic parameters were also examined. Symptomatic AHC patients were enrolled and followed prospectively. Patients were followed every 2 weeks in the first month then monthly for the following five months, with a follow-up visit si...

Potent viral suppression and improvements in alpha-fetoprotein and measures of fibrosis in Japanese patients receiving a daclatasvir/asunaprevir/beclabuvir fixed-dose combination for the treatment of HCV genotype-1 infection.

In the UNITY-3 study, 96% sustained virologic response (SVR12) rate was observed in Japanese patients with hepatitis C virus (HCV) genotype (GT)-1 infection treated for 12 weeks with fixed-dose daclatasvir, asunaprevir, and beclabuvir (DCV-TRIO). As HCV clearance may improve liver outcomes, we assessed hepatic fibrosis and alpha-fetoprotein (AFP), a hepatocellular carcinoma risk marker, pre- and post-treatment in UNITY-3.


Significance of detectable HCV RNA below the limit of quantification in patients treated with DAAs using standard and ultrasensitive protocols.

Predictive factors of HCV relapse after treatment with DAAs are poorly understood. In this study we aimed to assess whether the residual viral load positivity observed during or at the end of treatment (EOT) has an impact on viral outcome.

Single dose versus multiple doses of rituximab for preemptive therapy of Epstein-Barr virus reactivation after hematopoietic cell transplantation.

Epstein-Barr virus (EBV) reactivation is an unresolved medical issue after allogeneic hematopoietic stem cell transplantation (HSCT). Rituximab treatment is recommended for EBV reactivation after HSCT but the number of doses of rituximab to use is unclear. In this study, risk factors and outcomes of patients who needed 1 dose vs >1 doses of preemptive rituximab to clear EBV viremia were compared. A higher viral load was more likely to be associated with higher doses of rituximab. Patients whose EBV viremi...

Performance of the OraQuick Hepatitis C virus antibody test in oral fluid and fingerstick blood before and after treatment-induced viral clearance.

A reliable population screening strategy for hepatitis C virus (HCV) infection may be based in easy-to-use point-of-care (POC) tests for HCV antibodies, but validation data is needed before their potential widespread use in primary care or outreach practice. Besides, the sensitivity of these POC tests in patients with spontaneous or treatment-induced viral clearance is unknown.

Influenza A/H3N2 virus infection in immunocompromised ferrets and emergence of antiviral resistance.

Influenza viruses can cause severe life threatening infections in high-risk patients, including young children, the elderly and patients with compromised immunity due to underlying medical conditions or immunosuppressive treatment. The impaired immunity of these patients causes prolonged virus infection and combined with antiviral treatment facilitates the emergence of viruses with resistance mutations. The diverse nature of their immune status makes them a challenging group to study the impact of influenza...

Assessing Hepatitis C Spontaneous Clearance and Understanding Associated Factors: A Systematic Review and Meta-Analysis.

New advances in the treatment of hepatitis C provide high levels of sustained viral response but their expense limits availability in publicly funded health systems. The aim of this review is to estimate the proportion of patients who will spontaneously clear HCV and to identify factors that are associated with clearance, to support better targeting of directly acting antivirals. We searched Ovid Embase, Ovid Medline and Pubmed from 1st January 1994 to 30th June 2015 for studies reporting hepatitis C sponta...

The impact of ankle-foot orthoses on toe clearance strategy in hemiparetic gait: a cross-sectional study.

Ankle-foot orthoses (AFOs) are frequently used to improve gait stability, toe clearance, and gait efficiency in individuals with hemiparesis. During the swing phase, AFOs enhance lower limb advancement by facilitating the improvement of toe clearance and the reduction of compensatory movements. Clinical monitoring via kinematic analysis would further clarify the changes in biomechanical factors that lead to the beneficial effects of AFOs. The purpose of this study was to investigate the actual impact of AF...

Genetic variants in chemokine CC subfamily genes influence hepatitis C virus viral clearance.

Chemokine genes may influence both hepatitis C virus (HCV) spontaneous clearance in acute infection and treatment response in chronic infection. We conducted this study to evaluate whether the genetic variants in several CC family genes influence HCV spontaneous clearance and treatment response.

A hydroxyl PEG version of PEGylated liposomes and its impact on anti-PEG IgM induction and on the accelerated clearance of PEGylated liposomes.

Surface decoration of liposomes with polyethylene glycol (PEG), PEGylation, is recognized as a method to bestow liposomes with a prolonged circulation time following intravenous administration. However, many reports have emphasized that a first dose of PEGylated liposomes (PL) elicits an anti-PEG IgM antibody response that can trigger a rapid systemic clearance of a second dose of PL via a phenomenon that is referred to as "accelerated blood clearance (ABC)." Such a phenomenon is usually observed with PL th...

Metabolic Syndrome and the Iodine-Dose/Creatinine Clearance Ratio as Determinants of Contrast-Induced Acute Kidney Injury.

Finding patients at risk of developing contrast-induced acute kidney injury (CI-AKI) is important because of its associated complications. In the present study, the contribution of different variables, such as the presence of metabolic syndrome (MetS), the volume creatinine clearance (V/CrCl) ratio, the iodine-dose (I-dose)/CrCl ratio, or hypertension, to CI-AKI was evaluated.

Age and Bodyweight-Dependent Allometric Exponent Model for Scaling Clearance and Maintenance Dose of Theophylline from Neonates to Adults.

In population pharmacokinetic modeling, bodyweight is often incorporated as an important covariate using fixed (0.75) or single exponent model. In recent years, several variations of allometric models have been suggested for the prediction of drug clearance across a wide age range. The objective of this study is to develop and evaluate single exponent, bodyweight-dependent allometric exponent (BDE), age-dependent exponent (ADE) and segmented regression models for predicting clearance and maintenance dose of...

Dosimetric benefit of adaptive radiotherapy in the neoadjuvant management of canine and feline thymoma-An exploratory case series.

While surgery is the treatment of choice for thymomas, complete excision is not possible in a significant proportion of cases. For these patients, radiotherapy can be used as neoadjunctive, post-operative adjunctive or sole therapy. During radiotherapy, rapid biological clearance of tumour cells is often observed, requiring adaptation of the treatment plan. Adaptive radiation therapy (RT) is a dynamic process, whereby the treatment plan is altered throughout the treatment course due to changes in morphologi...

Increased insulin clearance in mice with double deletion of glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptors.

To establish whether incretin hormones affect insulin clearance, the aim of this study was to assess insulin clearance in mice with genetic deletion of receptors for both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), so called double incretin receptor knockout mice (DIRKO). DIRKO (n=31) and wild-type (WT) C57BL6J mice (n=45) were intravenously injected with D-glucose (0.35 g/kg). Blood was sampled for 50 minutes and assayed for glucose, insulin and C-peptide. Data w...

Survival of Viruses in Water.

Water, a frequent vehicle for the transmission of viruses, may permit their survival, but many environmental factors will have an adverse effect on the viral population. Risk evaluation requires identification of these factors and assessment of the inactivation rate of infectious viruses. A higher temperature means a faster reduction of the viral population, as do increased sunlight, higher antimicrobial concentration, or higher oxygen levels. Another documented impact is linked to the presence of indigenou...
