Cost-effective non-surgical treatment of chronic pressure ulcers in the community.

The Salisbury Pressure Ulcer Outreach Service successfully treats patients with chronic pressure ulcers that have not healed during routine community treatment. These patients have grade 4 pressure ulcers, involving extensive destruction, or damage to muscle and bone. A combination of scientific, seating and tissue viability expertise with a holistic approach results in non-surgical healing for 70% of patients. For those who still require surgery, outcomes are more successful with this approach, resulting in low recurrence rates. Prior to creation of the outreach service, patients were referred directly for surgical closure, resulting in high recurrence levels and long waiting lists. The authors compared costs of the Pressure Ulcer Outreach Service with the previous system of surgical closure. The model base case found that the Pressure Ulcer Outreach Service saved £8588 per patient, and that cost savings could be even greater if the outreach service was extended into preventative work.

Pharmacokinetics, safety, and tolerability of teduglutide, a glucagon-like peptide-2 (GLP-2) analog, following multiple ascending subcutaneous administrations in healthy subjects.

Teduglutide, a glucagon-like peptide-2 (GLP-2) analog, is currently being evaluated for the treatment of short-bowel syndrome, Crohn's disease, and other gastrointestinal disorders. The pharmacokinetics, safety, and tolerability of teduglutide in healthy subjects (N = 64) were assessed following daily subcutaneous administrations for 8 days in a double-blinded, randomized, placebo-controlled, ascending-dose study. Teduglutide treatments were administered as a 50-mg/mL (10, 15, 20, 25, 30, 50, and 80 mg) or 20-mg/mL (20 mg) formulation. Blood samples were collected on days 1 and 8, and plasma concentrations of teduglutide were measured using a liquid chromatography/tandem mass spectrometry method. Mean systemic exposures to teduglutide were very similar on days 1 and 8, suggesting minimal, if any, accumulation following once-daily repeated administrations. The apparent clearance of teduglutide following administration of the 50-mg/mL formulation was constant over the dose range, with mean values in male and female subjects of 0.155 and 0.159 L/h/kg, respectively. Peak plasma concentrations and total exposure of teduglutide after subcutaneous injection of a 20-mg/mL formulation (1.0 mL) were approximately 15% and 78% higher than those observed with the 50-mg/mL formulation (0.4 mL), respectively. Teduglutide treatments were safe and well tolerated. All but 1 adverse event was assessed as mild or moderate in severity. No relationship between teduglutide treatments and frequency of adverse events was observed, with the exception of injection site pain, which increased as a function of dose and injected volume. Results from the current study will assist in the dose selection in future efficacy studies.
