Insights

This study introduces a new model for evaluating plasma holds to protect blood supplies from infectious diseases. It extends previous work to multiple infections, improving safety and economic benefit analysis for blood donation screening.

Area of Science:

  • Transfusion Medicine
  • Infectious Disease Epidemiology
  • Public Health Policy

Background:

  • Plasma supply safety relies on donor screening for infectious diseases.
  • Current plasma hold policies are evaluated using models for single infections.
  • A need exists to assess hold policies considering multiple simultaneous infections.

Purpose of the Study:

  • To develop and present a mathematical model for evaluating plasma hold policies under multiple infectious disease scenarios.
  • To establish bounds for key metrics including interdiction probability and economic benefits.
  • To provide a framework for assessing the consequences of plasma holding strategies.

Main Methods:

  • The study extends existing models to accommodate multiple infectious diseases.
  • It utilizes marginal incidence rates of screened infections.
  • Mathematical bounds are derived for critical performance indicators.

Main Results:

  • The paper provides upper and lower bounds for the probability of interdicting infectious donations.
  • Expected numbers of infections interdicted per donation are calculated.
  • Net economic benefits of plasma holding policies are quantified.

Conclusions:

  • The developed model offers a robust method for evaluating plasma hold policies in the context of multiple infections.
  • This research aids in optimizing blood safety protocols and resource allocation.
  • The findings are crucial for public health strategies in transfusion medicine.

Drug Distribution: Plasma Protein Binding

Drugs predominantly attach to plasma proteins, with only a small percentage remaining unbound. The unbound portion can be calculated as one minus the bound fraction. Acidic drugs form large, inactive complexes by reversibly binding to plasma albumin, which prevents them from diffusing across biological barriers. These drug-protein complexes act as reservoirs for the drugs. As the concentration of unbound drugs decreases, these complexes quickly dissociate to release the free drug, maintaining...

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...

Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
