Findings from an exploratory study of the relationships between routine clinical laboratory tests and the clinical status of elderly patients living in a nursing home or congregate housing facility demonstrate that low albumin and anemia are associated with decreased survival and with self-care deficits, cognitive impairment, depression, and summary measures of the severity of medical illness. The interrelationships observed among these variables support the usefulness of the concept of failure to thrive. Although albumin can serve as a nutritional marker, findings on its relationship with sedimentation rate, triiodothyronine uptake, fasting plasma amino acids, and retinol-binding protein levels suggest that the low albumin related to failure to thrive is not a simple reflection of steady-state deficits in protein-calorie nutrition; it appears to be sensitive to more direct effects of disease and inflammation or to the interactions between nutrition and illness.
To explore the extent to which treatment of depression affects survival, we evaluated the association between use of antidepressant medications and death rates among the residents of a large residential-care facility for the elderly using a retrospective record-review study (N = 624). One year survival, among those taking antidepressants (10.9%), was 11.8% compared to 11.1% among the remainder of the population. A second study followed a group of 32 patients in the same institution who had participated in a therapeutic trial of nortriptyline treatment for major depression. Patients who experienced adverse medical events during treatment exhibited significantly increased mortality; among treatment completers, there was no significant relationship between mortality and therapeutic response. These findings suggest that the inability to tolerate treatment with an antidepressant can be considered a manifestation of physiologic frailty and increased vulnerability to mortality from disease. The previously reported decrease in survival among residential-care patients with major depression is not paralleled by a similar effect in those taking antidepressants. This may reflect selection factors with respect to the ability to tolerate antidepressants, rather an effect of treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
