Abstract
Objective: The authors examined the serotonin transporter gene-linked polymorphic region (5-HTTLPR) as a predictor of major depressive disorder and depressive symptoms after hip fracture, a common stressful medical event. Methods: This was a prospective, observational study of 23 elderly rehabilitation-hospital patients during their inpatient stay. Depressive symptoms were assessed by Hamilton Rating Scale for Depression (Ham-D) and PRIME-MD. Subjects were also genotyped for 5-HTTLPR. Results: Survival analysis showed that genotype significantly predicted time-to-major depressive episode. Subjects with an s allele (genotype s/l or s/s) had significantly higher Ham-D scores over 14 weeks of follow-up than those with the l/l genotype. Conclusion: Depressive symptoms and major depressive disorder in elderly persons after a stressful medical event may be associated with 5-HTTLPR genotype. This finding requires confirmation in a larger sample.
