[Hypothyroidism and aging: the search for protective factors].

Searching for aging key points is one of the main problems in geriatrics. More and more research in recent years has been devoted to the study of geroprotective mechanisms, the impact of various conditions and diseases on aging in general. Of particular importance is the determination of age-related involutive processes in the human body, whether they are part of normal aging or a condition that needs to be corrected to improve the functioning of organs and systems. An important mechanism of aging starts is a change in hormonal activity of endocrine glands, in particular in hormonal activity of thyroid. Frequency of hypothyroidism in advanced age explains relevance of the chosen topic. The aim of the review was to find out the role hypothyroidism in aging. The main task was to define, whether thyroid hormones decrease in older age was a protective factor or pathological process. A review of the literature over the past 10 years on subclinical treatment was carried out and we identified the most pressing issues associated with hypothyroidism and aging. We studied data on the relationship between hypothyroidism and major geriatric syndromes, with special attention paid to cognitive diseases and emotional disorders.

[Effect of bone anabolic therapy on bone remodeling and bone density in geriatric patients with osteoporosis and falling syndrome].

BACKGROUND: Older adults with severe osteoporosis are the most vulnerable group of geriatric patients. They are shown the purpose of anti-osteoporotic therapy, which should be effective and safe. Teriparatide showed a decrease in the risk of fractures, an increase in BMD. In Russia, the use of teriparatide in the geriatric population is extremely scarce. AIM: assess clinical course, bone metabolism parameters and efficacy of bone-anabolic therapy in elderly and senile patients with severe osteoporosis and falls. MATERIALS AND METHODS: The longitudinal prospective study included 100 patients 60 years and older with severe osteoporosis who had one or more falls within the last year. All patients were prescribed calcium and vitamin D preparations and bone-anabolic therapy (teriparatide 20 mg daily subcutaneously). The duration of follow-up was 24 months and included 3 visits: screening, at 12 and 24 months. The effectiveness of bone-anabolic therapy was carried out on the basis of assessing the frequency of new fractures, reduction of pain, changes in BMD according to X-ray densitometry, dynamics of bone metabolism markers. RESULTS: All patients had severe osteoporosis and aggravated comorbidity status, suffered a fall within the last year, and also low-energy fractures in the past. One in three patients had a vertebral fracture, one in five had a proximal femoral fracture. Prior to the start of the study, 61 patients received antiosteoporotic therapy. During the follow-up, 4 patients died, 96 patients completed the study. Against the background of teriparatide therapy, a decrease in the number of new cases of low-energy fractures and the number of patients with chronic pain was obtained. An increase in BMD was noted in the lumbar spine after 24 months and in the femoral neck after 12 months. There was no negative dynamics of the BMD. Also after 12 months, an increase in P1NP and C-terminal telopeptide of collagen type 1 was noted, after 24 months - osteocalcin and C-terminal telopeptide. CONCLUSION: The use of teriparatide can be recommended as an effective intervention to treat severe osteoporosis in geriatric patients with falls.
