Zusammenfassung
Das endokrine System ist untrennbar in die Regulation von körperlichen Veränderungen im Alterungsprozess und damit verbundenen Veränderungen der Lebensqualität involviert. In Anbetracht der steigenden Zunahme der älteren Population in der westlichen Welt ist die Offenlegung der hormonalen Mechanismen im Altersgang von höchstem Interesse. Endokrinologische Veränderungen im Alter umfassen die Abnahme von basalen Hormonspiegeln und der pulsatilen Hormonausschüttung sowie der Stimulierbarkeit der Hormonachsen. Folglich ändert sich auch die Körperzusammensetzung. Männer und Frauen zeigen unterschiedliche Muster in den altersabhängigen Veränderungen der Hormonachsen auf. Altern an sich ist ein Risikofaktor für endokrinologische Erkrankungen, wie Diabetes mellitus Typ 2, Schilddrüsenerkrankungen und Osteoporose, sowie für die Symptomkomplexe Sarkopenie und Frailty. Geschlechtsspezifische Unterschiede in Symptomen, Wechselwirkungen, Diagnostik und Therapien sind hierbei zu berücksichtigen. Bisherige Studien zur Hormonsubstitution erlauben weder für Männer noch für Frauen allgemeine Empfehlungen. Aufgrund der Multimorbidität der hochaltrigen Patientenpopulation erfordern neue Forschungsansätze einen multifaktoriellen Zugang.
Abstract
The endocrine system is intimately involved in modulating lifespan and quality of life. Facing an ever increasing proportion of aged people in the western society, there is great interest in understanding the complex interrelations between increasing age and hormonal regulation. Age-associated endocrinological changes comprise the decline of basal hormonal levels, pulsatile hormone distribution, and activity of hormonal axis, which result in changes in body composition. Men and women experience different age-associated alterations of the hormonal system. Aging per se is a risk factor for diseases like diabetes mellitus type 2, thyroid disorders, osteoporosis, frailty, and sarcopenia. Gender-specific differences with respect to symptoms, interactions, diagnosis, and therapy must be taken into consideration. Current data do not allow a general recommendation for hormonal substitution, neither for women nor for men. New research approaches following a multifactorial pathway are required to elucidate the complexity of age-associated endocrinological changes and to develop gender-specific therapies for endocrinological diseases.
