The real world experience of pediatric primary hyperoxaluria patients in the PEDSnet clinical research network.

The rarity of primary hyperoxaluria (PH) challenges our understanding of the disease. The purpose of our study was to describe the course of clinical care in a United States cohort of PH pediatric patients, highlighting health service utilization. We performed a retrospective cohort study of PH patients < 18 years old in the PEDSnet clinical research network from 2009 to 2021.

Healthcare utilization, quality of life, and work productivity associated with primary hyperoxaluria: a cross-sectional web-based US survey.

Primary hyperoxaluria (PH) is a family of ultra-rare, autosomal recessive, metabolic disorders associated with frequent kidney stones, chronic kidney disease and kidney failure, and serious complications due to systemic oxalosis, resulting in significant morbidity. We investigated the burden of PH among affected patients and caregivers. This cross-sectional, web-based survey was used to quantify the burden of PH, in terms of healthcare resource utilization, health-related quality of life, and work productivity and activity impairment among adults (≥ 18 years) with PH and caregivers of children (≤ 17 years) with PH in the US.

Diagnostic Code-Based Screening for Identifying Children with Primary Hyperoxaluria.

Purpose: We evaluated the utility of diagnostic codes to screen for patients with primary hyperoxaluria (PH) and evaluate their positive predictive value (PPV) in identifying children with this rare condition in PEDSnet, a clinical research network of pediatric health systems that shares electronic health records data.

Materials And Methods: We conducted a cross-sectional study of children who received care at 7 PEDSnet institutions from January 2009 through January 2021. We developed and applied screening criteria using diagnostic codes that generated 3 categories of the hypothesized probability of PH.

Hospital readmissions following initiation of nebulized arformoterol tartrate or nebulized short-acting beta-agonists among inpatients treated for COPD.

Background: Inpatient admissions for chronic obstructive pulmonary disease (COPD) represent a significant economic burden, accounting for over half of direct medical costs. Reducing 30-day readmissions could save health care resources while improving patient care. Recently, the Patient Protection and Affordable Care Act authorized reduced Medicare payments to hospitals with excess readmissions for acute myocardial infarction, heart failure, and pneumonia.

Risk of all-cause hospitalization in COPD patients initiating long-acting or short-acting beta agonist therapy.

Objective: This retrospective claims study investigated the rates of all-cause hospitalization among chronic obstructive pulmonary disease (COPD) patients initiating treatment with short-acting beta agonists (SABA) or long-acting beta agonists (LABA).

Methods: Data from the 5% national sample of Medicare enrollees for 2006-2008 were used. Patients initiating COPD therapy were identified as those with no COPD therapy for ≥ 6-months prior to initiating SABA or LABA (administered via dry-powder inhalers, metered-dose inhalers, or nebulizer) treatment.

Efficacy and safety evaluation of ciclesonide in subjects with mild-to-moderate asthma not currently using inhaled corticosteroids.

Inhaled corticosteroids (ICSs) are a first-line treatment for persistent asthma. This study was designed to compare the efficacy and safety of ciclesonide (CIC) in subjects with mild-to-moderate persistent asthma not using an ICS. This was a multicenter, double-blind, parallel-group, placebo-controlled, 16-week study in subjects who were > or =12 years old, had a > or =6-month history of persistent asthma, a forced expiratory volume in 1 second (FEV(1)) of > or =60 to < or =85% predicted, and who were not using an ICS < or =30 days before study entry.

Efficacy and safety evaluation of ciclesonide in mild-to-moderate persistent asthma previously treated with inhaled corticosteroids.

Inhaled corticosteroids (ICSs) are recommended as first-line treatment for persistent asthma. This study was designed to evaluate the ability of ciclesonide (CIC) in subjects with stable asthma previously receiving another ICS or ICS/long-acting beta(2)-agonist (LABA) to maintain asthma disease control. In this 12-week, multicenter, double-blind, parallel-group study, subjects aged > or =12 years with stable mild-to-moderate persistent asthma were switched at randomization from an ICS or ICS/LABA to CIC, 80 microg twice daily (CIC80 b.

A new solution-based intranasal triamcinolone acetonide formulation in patients with perennial allergic rhinitis: how does the pharmacokinetic/pharmacodynamic profile for cortisol suppression compare with an aqueous suspension-based formulation?

The present study was undertaken to describe the pharmacokinetics of a new solution-based intranasal triamcinolone acetonideformulation (Tri-Nasal) in patients with perennial allergic rhinitis and to use a pharmacokinetic/pharmacodynamic (PK/PD) simulation approach to compare the potential effects on plasma cortisol with that of an aqueous suspension-based nasal triamcinolone acetonide formulation (Nasacort AQ). Data from an open-label, randomized, three-way crossover study in patients with perennial allergic rhinitis receiving three doses (100, 200, and 400 microg) of a nasal solution-based triamcinolone acetonide formulation (Tri-Nasal) over 7 days were used to describe the pharmacokinetics of this formulation. Available literature data for a suspension-based aqueous triamcinolone acetonide formulation (Nasacort AQ) were used to describe its pharmacokinetic profile after similar single doses of 110, 220, and 440 microg.
