The purpose of this study is to evaluate the antiviral effect of repeated oral dosing of JNJ 53718678 compared to placebo in healthy adult participants infected through inoculation with respiratory syncytial virus (RSV)-A Memphis 37b virus.
This is a multicenter, single arm, 96-week open-label study of the safety and virologic efficacy of fixed dose combination Dolutegravir/Lamivudine/Abacavir (DTG/3TC/ABC FDC) initiated during acute HIV infection (AHI).
The primary objective of I-CARE is to assess prospectively the presence and the extent of safety concerns (cancers, especially, lymphoma, and serious infections risks) for anti-TNF alone or in combination with thiopurines among IBD patients. We will stratify the risk of cancers and serious infections according to IBD phenotype and disease activity (clinical, radiologic and endoscopic).
The investigators will determine the efficacy of an innovative short regimen of methenamine hippurate on prevention of post-operative UTI in patients requiring short-term catheterization after pelvic reconstructive surgery through a single-blind, randomized controlled trial. Primary outcome will be the rate of symptomatic UTI within 3 weeks of catheter removal. The investigators will study cost-effectiveness, antibiotic resistance profiles, and adverse drug effects. Findings may reduce antibiotic use and nosocomial UTIs.
Approximately, 3% of males and 8% of females will develop a urinary tract infection (UTI) during childhood, and most of these will be effectively treated by short-term antibiotic therapy. A subset of these children (20-48%), will develop recurrent UTI (RUTI), which may have long-term effects in the form of hypertension or renal damage. In an effort to prevent RUTIs physicians prescribe sulfamethoxazole-trimethoprim (Septra) or nitrofurantoin as low dose antibiotic prophylaxis. However, recent evidence suggests that during prophylactic therapy the body is exposed to antibiotic levels capable of increasing antibiotic resistance and bacterial virulence. This has been shown to be true in the uropathogens E. coli and Staphylococcus saprophyticus, yet it is not known if Enterococcus sp. demonstrate similar mechanisms. Additionally, antibiotics have been shown to disrupt the natural balance of the human microbiome, potentially leading to major long term problems. As a uropathogen, enterococci consistently rank in the top 3 causes of RUTI, especially in children under 3 years of age. Additionally, Enterococcus is notorious for developing antibiotic resistance and studies have shown that children with enterococcal UTIs exhibit a higher rate of recurrence than those with non-enterococcal UTIs. The investigators hypothesize the current practice of antibiotic prophylaxis in children with RUTI is detrimental and can change the bacterial and sensitivity profiles of these patients.
Fluoroquinolones (FQ) are among pivotal antibiotic treatments in difficult-to-treat infections. Their efficacy has been shown to be linked to the ratio area under the curve (AUC) of their plasma concentrations over the minimum inhibitory concentration (MIC) of the bacteria treated. Eventually, Forrest et al., reported in gram-negative infections that an AUC/MIC above 125 conducted to a 80 to 90% clinical success whereas success decrease to 30 to 40% in patients with an AUC/MIC below this threshold. These results have been reproduced recently by Zelenitsky et al. in intensive care unit (ICU) patients with threshold similar to the one obtained by Forrest et al. Lastly, elevated concentrations of FQ should be related with the onset of adverse events. Thus, therapeutic drug monitoring (TDM) of FQ appears of potential interest, particularly in case of severe infections (intensive care unit (ICU) patients) or complicated and cost-related infections (osteoarticular infected (OAI) patients), with an increasing level of evidence of its use. However, FQ TDM requires access to the full AUC of the drug with the need of many samples drawn to patients. This appears to be irreconcilable with clinical practice but can be achieved using population pharmacokinetic (PkPop) modelling. PkPop allows estimating pharmacokinetic parameters of the drug by introducing covariates (demographic, biological, clinical…) and modelling inter-individual pharmacokinetic variability. The model created allows then accessing to individual parameters of patients and thus, estimating concentrations and AUC of the FQ. This approach may also be used in clinical practice to determine a limited sampling strategy allowing an adequate estimation of AUC with a minimum of samples.
The purpose of this study is to determine if the use of inhaled beclomethasone after a community-acquired respiratory viral infection in a lung transplant recipient decreases the risk of the subsequent development of chronic lung allograft dysfunction.
Death in Ataxia telangiectasia (A-T) is usually due to cancer or chronic lung failure around 20 years of age. Despite low lymphocyte counts (CD3, CD4, CD8 and CD19), IgA and IgG subclass deficiency opportunistic and acute severe respiratory infections are rare. The prevailing wisdom is that an immunoglobulin replacement therapy is not necessary in most of the patients. However no placebo controlled trials have been performed so far. The aim of this trial was to investigate the prevalence of mild and severe respiratory infections and / or chronic cough in classical A-T patients compared to healthy controls.
Objectives: 1) To evaluate la proportion of hepatitic C virus (HCV)-monoinfected patients who show sustained virologic response (SVR) to treatment including direct-acting antivirals (DAAs) in the clinical practice in clinical units that treat infectious diseases and 2) to determine the frequency of adverse events, including those that are severe and/or cause treatment interruption, in DAA-based therapy in this setting. Design: Multicentric, prospective post-authorised cohort study. Setting: Hospitals of the Hepatitis Study Group (GEHEP) of the Spanish Society of Infectious Diseases and Microbiology (SEIMC). Study population: HCV-monoinfected patients that initiate DAA-based treatment outside clinical trials. Variables: The primary efficacy outcome variable is the proportion of patients who reach undetectable HCV-RNA 12 weeks after the scheduled end of therapy (SVR12). The primary safety outcome variable is the percentage of subjects who discontinue therapy due to adverse events. Statistical analysis: A descriptive study will be performed, as well as a double sensibility analysis of the frequency of SVR12 using both an intention-to-treat and an on-treatment approach. Those variables that are associated with SVR12 with a p-value <0.2 will be included in a logistic regression analysis in which SVR12 will be the dependent variable.
