Posttraumatic hypopituitarism is associated with an unfavorable body composition and lipid profile, and decreased quality of life 12 months after injury. [J Clin Endocrinol Metab] Journal article | | Title | Posttraumatic hypopituitarism is associated with an unfavorable body composition and lipid profile, and decreased quality of life 12 months after injury. | | Author(s) | Klose M, Watt T, Brennum J, Feldt-Rasmussen U | | Institution | Department of Medical Endocrinology, University Hospital of Copenhagen, Rigshospitalet, 2100 Copenhagen, Department of Neurosurgery, Copenhagen University Hospital Glostrup, 2600 Glostrup, Denmark. | | Source | J Clin Endocrinol Metab 2007 Jul 24. | | Abstract | Objective: To describe body composition, lipid profile, and health-related quality of life (HRQL) in patients with traumatic brain injury (TBI) in relation to the development of posttraumatic hypopituitarism.
Design: Cross-sectional with a nested prospective sub-study.
Patients: The cross-sectional cohort included 104 hospitalized patients with TBI (26F/78M; age: median 41yrs. (range 18-64); BMI: 25kg/m(2) (17-39); severity: mild (Glasgow Coma Scale score (GCS) 13-15) n = 44, moderate (GCS 9-12) n = 20, severe (GCS < 9) n = 40). A nested cohort of 46 patients was followed prospectively. Measurements: Body mass index (BMI), waist circumference, lipid profile, total- and regional- fat mass was assessed 3 and 12 months (prospective) or only 12 months (cross-sectional) post-traumatically. HRQL questionnaires (NHP, EQ-5D and the GH deficiency specific instrument - QoL-AGHDA) were completed 'pre-traumatically', 3 and 12 months (prospective) or only 12 months (cross-sectional) post-traumatically.
Results: Patients with posttraumatic hypopituitarism had higher age-, gender- and BMI- adjusted 12 months LDL-cholesterol, waist circumference, and total fat mass (P < 0.05 in all cases), and a higher increase in total cholesterol (P = 0.01) during follow-up compared with sufficient patients. These findings were unrelated to 12 months IGF-I and IGF-I SD-scores. Hypopituitary patients also had worse age-, BMI- and TBI severity- adjusted overall EQ-5D VAS (P = 0.03) and QoL-AGHDA (P = 0.01) scores, and worse NHP dimension scores of sleep (P = 0.03), energy (P = 0.02), and social isolation (P = 0.04), compared to patients with an intact pituitary function.
Conclusion: Posttraumatic hypopituitarism was an independent predictor of the classical phenotypic features of hypopituitarism including an unfavorable lipid and body-composition profile, as well as worsened HRQL. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
