Patent ID: 8452543

Claim:
A computer-implemented method of predicting the likelihood of a microbial population of cells associated with a pathophysiological condition of acquiring resistance to a therapeutic agent, comprising: providing a computer-implemented simulation in a computer system including at least an input/output system and a mathematical model of growth response over a period of time of a microbial cell population in contact with a therapeutic agent, wherein the mathematical model comprises, as operably linked components: equations for calculating in parallel and over a specified time period a rate of change of concentration of the therapeutic agent in the microbial cell population, a rate of change of cellular susceptibility to the therapeutic agent and a rate of change of burden in a surviving microbial cell population; and initial parameter values for the equations corresponding to time, infusion rate of the therapeutic agent, volume of distribution, clearance of the therapeutic agent, concentration to achieve 50% of maximal kill rate of a microbial cell population, and maximum size of a microbial cell population and constants for maximum adaptation and adaptation rate of a microbial cell population and growth rate, maximum kill rate and sigmoidicity of a microbial cell population; inputting parameter values into the mathematical model to determine at least susceptibility of the cells to the therapeutic agent and growth of a microbial cell population during contact therewith over the period of time; generating output values predicting cellular susceptibility and cellular growth at incremental points over the time period; and correlating, at or near the end of the time period, a decrease in cellular susceptibility output values and an increase in cell population growth values in a microbial cell population which initially demonstrated susceptibility to the therapeutic agent with the likelihood of acquisition of resistance of the microbial cell population to the therapeutic agent, thereby predicting the likelihood of acquisition of resistance to the therapeutic agent.
