[Pituitary diseases in elderly patients with chronic renal insufficiency].

Chronic renal failure (CRF) in the elderly is a cause of multiple endocrine dysfunctions. The three most common pituitary axes involved are the thyrotrope, lactotrope and gonadotrope axes. Thyroid dysfunction may be the consequence of thyroid or pituitary failure. Hyperprolactinemia results in gonadal failure and is present in 30% of patients. Early presentation of menopause and andropause are common in patients with CRF. Sexual hormonal replacement is controversial and must be individually tailored. We propose a systematic screening in the elderly with CRF: determination of TSH, TPO antibodies and cervical palpation, measures of PRL, LH, FSH and testosterone to explore lactotrope and gonadotrope axis.
