Quality of life and fear for hypoglycaemia in patients with type 2 diabetes mellitus. / Calidad de vida y grado de preocupación por las hipoglucemias en pacientes con diabetes mellitus tipo 2.

OBJECTIVES: Hypoglycaemia can negatively impact many aspects of type 2 diabetes mellitus (T2DM) management. The aim was to determine the impact of hypoglycaemia and the fear for hypoglycemic episodes on HRQoL in T2DM patients in Spain, as well as healthcare professionals' attitudes and knowledge of these issues. PATIENTS AND METHODS: An observational, cross-sectional study, with consecutive recruitment of T2DM patients in 661 healthcare centers, between September 2010 and May 2011. Sociodemographic and clinical variables were recorded. HRQoL (ADDQoL questionnaire) and fear for hypoglycaemia (HFS-II) were evaluated. Two groups were compared: with and without reported hypoglycaemia in the previous 6 months. Physicians responded 4 questions (visual analogue scales). RESULTS: 4.054 patients participated, of which 3,812 were selected [mean age (SD)=64 (11) years; male=54%; 10 (7) years for diagnostic of T2DM]. Patients with hypoglycaemia (45%) expressed higher fear for hypoglycemia [31.32 (15.71) vs. 18.85 (16.03); p<0.0001] and the overall impact of T2DM on their HRQoL was more negative [-2.48 (1.61) vs. -1.64 (1.36); p<0.001]. Respondent physicians occasionally used HRQoL questionnaires, knew about hypoglycaemia risk, explored fear for hypoglycaemia and modified treatments accordingly. CONCLUSIONS: T2DM patients with hypoglycaemia show an increase of fear for them, negatively affecting T2DM patients HRQoL. However physicians know the risk of hypoglycaemia, they explore the fear for hypoglycemic episodes occasionally.

Results from a national survey on the management of primary hyperparathyroidism.

BACKGROUND: Management of primary hyperparathyroidism (PHPT) continues to be challenging. At the Third International Workshop on PHPT, recent data on this disease were reviewed and new clinical recommendations were developed. There are few data on the influence of new guidelines in clinical practice. AIM: We designed an online survey that was sent to all Spanish hospital endocrinology services. METHODS: The questionnaire included 28 questions about diagnosis and management of PHPT. Ninety-nine of 131 sites (76%), giving health coverage to 70% of Spanish population, completed the survey. RESULTS: The reported incidence of PHPT was 9.95/100,000 person-years. Heighty percent of patients were asymptomatic. Each center performed a median (Q1, Q3) of 12 (6, 20) parathyroidectomies/year. The median (Q1, Q3) percentage of curative interventions (at first trial) was 90% (80, 95). The main reasons for not performing surgery were, by decreasing frequency: surgery contraindication, patient's refusal, loss of monitoring, limited surgery experience. Localization techniques were used in 83% of cases. The main criteria for parathyroidectomy in asymptomatic patients were Ca≥2.875 mmol/l (79%), Tscore ≤-2.5 SD at any site (91%), age <50 yr (80%) and glomerular filtration rate <60 ml/min/1.73 m 2 (82%). Minimally invasive surgery was performed in 42% of centers. Frequency of biochemistry and bone density determinations for non-surgically managed patients was in accordance with international guidelines. CONCLUSIONS: The clinical practice of Spanish endocrinologists is consistent with the recommendations of the guidelines from the Third International Workshop for the management of PHPT.

Identification of metabolic bone disease in patients with endogenous hyperthyroidism: role of biological markers of bone turnover.

Active hyperthyroidism is associated with reduced bone mass. Nevertheless, not all patients show the same risk for developing osteoporosis. Our aim was to analyze some clinical and biochemical potential predictors of low bone mass in hyperthyroid patients. We studied 127 consecutive hyperthyroid patients (110 females, 17 males; aged 42 +/- 16 years). Bone mineral density (BMD) was measured by dual X-ray absorptiometry (DXA) at lumbar spine (LS; L2-L4) and femoral neck (FN). Data were expressed as g/cm2 and T-score. Patients were placed into two groups based on recent WHO criteria: Group A, no osteoporosis (n = 98); and group B, lumbar or femoral osteoporosis (n = 29). Study protocol included evaluation of osteoporosis risk factors, anthropometrical variables, thyroid function, and bone turnover markers. Receiver-operating characteristic (ROC) plots for the precision of bone markers and multivariate analysis for the prediction of BMD and osteoporosis were performed. Group B showed greater age and proportion of menopausal females; lower weight, height, and calcium intake; longer duration of menopause; and greater levels of total and bone alkaline phosphatase and of urine hydroxyproline. No differences in thyroid function, osteocalcin, tartrate-resistant acid phosphatase, and type I collagen C-telopeptide (ICTP) were found. The best predictive model accounted for 46% and 62% of the variability of lumbar and femoral BMD respectively and correctly classified 89% of the osteoporotic hyperthyroid patients. No significant difference in ROC plots was observed. It is concluded that hyperthyroid patients with lumbar or femoral osteoporosis show a typical clinical and biochemical profile illustrating that the relationship between BMD and bone markers is better in high turnover states. Classical bone turnover markers show high performance in the evaluation of hyperthyroid bone disease.

Hyperinsulinemia in polycystic ovary syndrome: relationship to clinical and hormonal factors.

We analyzed the association between hyperandrogenism and hyperinsulinemia, and their relationship to body mass index, in a large series of patients with polycystic ovary syndrome (PCOS). A characteristic hormonal profile was sought in women with marked hyperinsulinemia. The patient group consisted of 73 women with PCOS, ranging in age from 16 to 29 years. The control group consisted of 34 healthy women with no evidence of hyperandrogenism, aged 19-30 years. None of the patients or control women had a body mass index above 27 kg/m2. Follicle-stimulating hormone, luteinizing hormone, prolactin, testosterone, estradiol, androstenedione, dehydroepiandrosterone sulfate, sex hormone binding globulin, 17-hydroxyprogesterone, and free cortisol were determined by radioimmunoassay. The free testosterone index was calculated. The oral glucose tolerance test was used to analyze basal insulinemia, maximum insulin peak, and the insulinemia/glycemia index. In the group with PCOS body mass index was greater, free testosterone index was higher, and levels of dehydroepiandrosterone sulfate, testosterone, 17-hydroxyprogesterone (P < 0.001) and androstenedione (P < 0.05) were higher than in the control group. Of the insulin parameters, basal insulinemia, maximum insulin peak, and insulinemia/glycemia index were higher in the patient group (P < 0.001). In patients with marked insulinemia, free testosterone index was more markedly elevated, and gonadotrophin levels were normal. Our data confirm that a characteristic pattern of hyperinsulinemia is associated with PCOS. We found no causal relationship between hyperinsulinemia and androgen levels. A characteristic hormonal pattern was found in patients with marked hyperinsulinemia.

Reduction of endogenous, ovarian and adrenal androgens with ketoconazole does not alter insulin response in the polycystic ovary syndrome.

Several different strategies were used to investigate the relationship between hyperandrogenism and hyperinsulinemia associated with polycystic ovary syndrome. Ketoconazole was given orally (400 mg/day) for 9 months to evaluate the effect of reduction in ovarian and adrenal androgens on insulin response (oral glucose tolerance test) in 35 women with polycystic ovary syndrome. Androgenic steroids (testosterone, androstenedione, dehydroepiandrosterone sulphate, and free testosterone index) decreased (p < 0.01), but basal insulinemia, maximum peak insulin, and insulin/glucose ratio showed no significant changes. One month after treatment was stopped, free testosterone index, and serum concentrations of androstenedione and testosterone, increased (p < 0.05), but no alterations were noted in insulin parameters. Body mass index was stable throughout the ten-month study period. Our findings suggest that endogenous androgens, no matter whether they are of ovarian or adrenal origin, do not play a major role in the modulation of hyperinsulinemia in patients with polycystic ovary syndrome.

Ketoconazole therapy: hormonal and clinical effects in non-tumoral hyperandrogenism.

The aim of this study was to assess the usefulness of ketoconazole as a therapeutic alternative to polycystic ovary syndrome. The study group comprised 37 women with signs of hyperandrogenism (hirsutism, acne) and oligomenorrhea. A low dose (400 mg/day) of ketoconazole was tested in a 9-month prospective clinical study. Clinical response (Ferriman & Gallway score, acne) and modifications in hormone pattern (luteinizing hormone, follicle-stimulating hormone, estradiol, testosterone, prolactin, 17-hydroxy-progesterone, androstenedione, steroid hormone-binding globulin, dehydroepiandrosterone sulfate, cortisol, adrenocorticotropin (ACTH) and free testesterone index) were measured, and ACTH stimulation tests were performed. Tolerance and side-effect also were assessed. After 9 months of ketoconazole treatment, the patients' Ferriman & Gallway scores (18.26 +/- 4.6 vs 12.4 +/- 4.1; p < 0.001) and acne had improved markedly. Hormone patterns also became more favorable, with decreases in androgenic steroids (testosterone, androstenedione, free testosterone index and dehydroepiandrosterone sulfate; p < 0.01) and increases in estradiol (p < 0.01). Basal cortisol levels and cortisol after ACTH stimulation were not changed significantly, remaining within the reference range. Increases in ACTH were observed only in the 3rd month (p < 0.01). Initial levels of androgenic steroids were correlated inversely with their percentage decrease in successive samplings. Decreases in adrenal androgenic steroids were associated with an increase in steroid hormone-binding globulin. The side-effects of treatment, although not severe, caused some discomfort and led to a high drop-out rate (30%).(ABSTRACT TRUNCATED AT 250 WORDS)

[Lipid profile of hyperandrogenic women undergoing treatment with ketoconazole and its relationship with the evolution of the hormone pattern]. / Perfil lipídico de la paciente hiperandrogénica en tratamiento con ketoconazol y su relación con la evolución del patrón hormonal.

BACKGROUND: Previous studies have demonstrated changes in the lipidic profile following treatment with ketoconazole. However, the possible influence in patients with hyperandrogenism treated with this drug and its possible relation with the evolution of the hormonal pattern is unknown. RESULTS: Thirty-seven women with no tumoral hyperandrogenism treated with ketoconazole for 9 months (400 mg/day) were studied during treatment and one month after suppression of the medication. The study included the evaluation of total cholesterol, HDL cholesterol, triglycerides, LDL cholesterol and hormonal determinations of estradiol, androstenedione, testosterone, dehydroepiandrosterone, sulphate and sex hormone binding globulin. RESULTS: A rapid and significant decrease of LDL cholesterol and total cholesterol was observed (p < 0.01) which was reversible upon discontinuation of treatment. The HDL cholesterol levels and triglycerides did not modify. The final hormonal profile was more favorable with a significant reduction of testosterone and dehydroepiandrosterone sulphate (p < 0.01) and an increase in estradiol (p < 0.01). No statistical correlation was observed between the changes of sexual steroids and the changes in the lipidic pattern. CONCLUSIONS: In patients with non tumoral hyperandrogenism treated with ketoconazole the modifications of the steroid hormone profile do not appear to be related with changes in lipidic metabolism.

Bone mass in females with different thyroid disorders: influence of menopausal status.

The aim of this study was to evaluate the effect of thyroid functional state on cortical and trabecular bone mineral density (BMD) (g/cm2) in premenopausal and postmenopausal women. Control subjects were used as a reference population to calculate Z-scores from patient data. In patients with active hyperthyroidism, BMD was reduced in lumbar spine (LS; P < 0.01), femoral neck (FN; P < 0.01) and Ward triangle (WT; P < 0.0001) in comparison with reference standards. In premenopausal women treated in the past for hyperthyroidism or treated at the time of study with L-thyroxine in non-TSH-suppressive doses, there was no significant decrease in BMD. In postmenopausal women with hyperthyroidism in remission, we found a significant decrease in BMD in LS (P < 0.01), FN (P < 0.05) and WT (P < 0.0001). In postmenopausal women treated with L-thyroxine (L-T4), there was a significant decrease in BMD in LS (P < 0.01) and WT (P < 0.01). There was a significant negative correlation between the cumulative dose of L-T4 and BMD in FN (r = -0.688, P < 0.05) and WT (r = -0.657, P < 0.05) in postmenopausal women. Our findings suggest that the deleterious effects of thyroid hormones on BMD are accentuated in areas consisting predominantly of trabecular bone, e.g., the LS and WT. Postmenopausal women subjected to excess thyroid hormone represent a population at greater risk for osteoporosis.
