Abstract

Biological and behavioral change occurs throughout the lifespan. The nature and rapidity of change during adolescence is striking. The effects of rapid growth, sexual maturation, and psychological reorganization on pharmacodynamics and pitarmacokinetics must be considered during studies on teenagers.

It is important to consider the large amount of variability in the timing of normal developmental events. The concept of developmental rather than chronological age should be considered. Measurement of organismic and behavioral variables includes whole organism measures such as body height, weight, surface area, body mass index, self-concept, sexual identity/role, and many other behavioral measures. Pubertal development may be assessed by sexual maturity ratings. Bone age may be a particularly useful estimate of developmental status. Biochemical measures include gonadotropin, sex steroids, other hormonal or hormone receptor values.

      This personalized approach demonstrates that risk-based interventions can be safely executed in these complex patients, though further studies are warranted [99]. Additional ways to optimize therapy and potentially reduce the risk of acute GVHD in AYAs could include altering the dosages of chemotherapeutic and supportive care drugs, primarily through the use of pharmacokinetic and pharmacogenomic data, as age-related changes in body composition and specific genetic polymorphisms are known to contribute to differences in drug metabolism [100–103]. Pharmacokinetic-guided dosing of busulfan has become the standard-of-care in pediatric HCT, as this approach has demonstrated lower rates of relapse as well as decreased toxicity, including acute GVHD [104].

      During the normal pubertal process, adolescents experience numerous physiological, physical, and psychosocial changes that can affect drug disposition. For example, changes in height and weight, body mass index, body composition, and hormone levels, along with use of oral contraceptives, alcohol, tobacco, and recreational drugs, all may effect pharmacokinetics [54,55]. Changes in body composition include an increase in fat mass in females and a decrease in fat mass and increase in muscle mass for males, changes potentially affecting the volume of distribution as well as plasma drug concentrations [55].
