Outcomes associated with hypogonadism in women with chronic kidney disease

The successful use of renal replacement therapy has resulted in longer survival and a population of older patients with chronic kidney disease (CKD) that includes patients with other significant preexisting illnesses. In this review, we analyze the short-term and long-term outcomes associated to persisting hypogonadism in CKD patients. The short-term manifestations, commonly observed in normal postmenopausal women, are either a rare complaint of women with CKD or are frequently attributed to the uremic state. These symptoms include hot flashes, sleep disturbances and depression, sexual dysfunction, vaginal dryness and atrophy, urinary incontinence, and skin aging and wrinkling. The long-term outcomes of hypogonadism have potentially devastating effects on bone, cardiovascular system, and cognitive function, which could significantly alter the quality of life and survival of women with stage 5 CKD (CKD-5). Postmenopausal osteoporosis has been recognized as an important entity associated with renal osteodystrophy, and efforts have begun to tackle the reduced bone-mineral density (BMD) and increased fracture rate seen in this population. Similarly, cardiovascular disease represents the major cause of death in the CKD-5 population, with a 10 to 20 times greater mortality than in the general population. The accumulating evidence for a possible link between osteoporosis and atherosclerosis is discussed, as well as new directions in the understanding of postmenopausal osteoporosis in the context of renal bone disease, under the guidance of the Global Bone and Mineral Initiative endorsed by the Kidney Disease: Improving Global Outcomes initiative. Nephrologists must face gynecological issues with their women patients and design interdisciplinary clinical studies that include strategies that utilize well-tested and newer drug regimens in the management of osteoporosis, cardiovascular disease, and other postmenopausal manifestations in CKD-5 patients.
