RESUMO

PURPOSE: The present study aims to evaluate the serum concentrations of 25 hydroxyvitamin D[25(OH)D] in individuals aged ≥80 years, independent, free-living in Sao Paulo, Brazil (Lat 23.5 oS), and to investigate their associations with musculoskeletal system, physical performance and health markers. METHOD: This cross-sectional study included 212 community dwellers aged ≥80 years and evaluated serum 25(OH)D, PTH, calcium, albumin, phosphorus, creatinine, bone markers, and bone mineral density. Physical performance was evaluated with stationary march, Flamingo, and functional reach tests, questionnaires to assess falls and fractures in the previous year, energy expenditure (MET), and Charlson index. Physical activity was evaluated with the International Physical Activity Questionnaire. RESULTS: Vitamin D deficiency (<20 ng/mL) was observed in 56% and severe vitamin D deficiency (<10 ng/mL) in 13% of those individuals. Serum concentrations of 25(OH)D were significantly and positively associated with BMD total hip (p = 0.001), femoral neck (p = 0.011) and 33% radius (p = 0.046) BMDs, MET (p = 0.03) and functional reach test (p = 0.037) and negatively with age (p = 0.021), PTH (p = 0.004) and osteoporosis diagnosis (p = 0.012). Long-lived individuals with 25(OH)D ≥ 20 ng/mL had higher total hip and femoral neck BMDs (p = 0.012 and p = 0.014, respectively) and lower PTH (p = 0.030). In multiple linear regression analysis, age and osteoporosis diagnosis remained negatively associated with 25(OH)D levels (p = 0.021 and p = 0.001, respectively), while corrected calcium and cholecalciferol use remained positively associated (p = 0.001 and p = 0.024, respectively). CONCLUSION: We observed high vitamin D inadequacy prevalence in those Brazilian community dwellers' oldest old. Serum concentrations of 25(OH)D were positively associated with bone mass and dynamic balance, and negatively with PTH and osteoporosis diagnosis. Additionally, 25(OH)D ≥ 20 ng/mL was associated with better bone mass and lower PTH levels.

RESUMO

Hypoparathyroidism remains the single endocrine deficiency disease that is not habitually treated with the missing hormone. In this article, we aim to provide a review of the conventional approach and the novel therapies as well as an overview of the perspectives on the treatment of this rare condition. We conducted a literature review on the conventional therapy using vitamin D analogs and calcium salts, indications for thiazide diuretics and phosphorus binders, PTH analogs history and usage, and the drugs that are currently being tested in clinical trials. Conventional treatment involves calcium salts and vitamin D analogs. Thiazide diuretics can be used to reduce hypercalciuria in some cases. A low-phosphate diet is recommended, and phosphate binders are rarely needed. During pregnancy, a careful approach is necessary. The use of PTH analogs is a new approach despite the limitation of high cost. Studies have included modified PTH molecules, calcilytics, microencapsulation of human parathyroid cells, and allotransplantation.

RESUMO

BACKGROUND AND OBJECTIVE: Non-communicable diseases like systemic arterial hypertension (SAH) and dyslipidemia are poorly studied in terms of patient journey aspects. This semi-systematic review provides evidence synthesis for the management of SAH and dyslipidemia in Brazil and also discusses challenges faced by patients at the local level along with a suggested care approach by local experts. METHODS: A semi-systematic review using both structured literature databases (Embase and Medline) and unstructured scientific records (WHO, IPD, MOH and Google) on hypertension and dyslipidemia in the English language from 2010 to 2019 was performed by reviewers. After two-level screening based on pre-defined criteria, patient journey touchpoints and prevalence information were extracted from the included articles. Data gaps were bridged through the insights of local experts. RESULTS: Prevalence of hypertension and dyslipidemia in Brazil were 23% and 40.8%, respectively. Awareness of dyslipidemia was found in a larger proportion (58.1%) than in SAH (22.2%). Similarly, screening for hypertension (97%) and dyslipidemia (55.4%) were found to be effective, while treatment was (62.9%) and (30.0%) for hypertension and dyslipidemia, respectively. CONCLUSION: There were important gaps on patient awareness and treatment of dyslipidemia and hypertension. Limited patient education, regional disease distribution, and treatment allocation, along with limited resources for diagnosis and treatment are the key challenges.

RESUMO

Osteoporosis is a prevalent skeletal disorder in postmenopausal women. REMS represents a potential technology for osteoporosis diagnosis in clinical practice. OBJECTIVE: To assess the accuracy of Radiofrequency Echographic Multi Spectrometry (REMS) technology in diagnosing osteoporosis in comparison with dual X-ray absorptiometry (DXA) on a population of Brazilian women. METHODS: A population of women age ranged between 30 and 80 was recruited at DXA Service of São Paulo School-Hospital, Brazil. They underwent REMS and DXA scans at the axial sites. The REMS accuracy for the osteoporosis diagnosis was evaluated in comparison with DXA on both sites. The intra-operator and inter-operator coefficient of variation (CV) was also calculated. RESULTS: A total of 343 patients were enrolled in the study. Erroneous scans due to poor quality acquisitions with both methods or to other technical reasons were excluded; 227 lumbar spine exams and 238 hip exams were acceptable for comparison analysis. The comparison between REMS and DXA outcomes showed that the average difference in BMD (expressed as bias±1.96 SD) was -0.026±0.179g/cm2 for the spine and -0.027±0.156g/cm2 for the femoral neck. When accepted 0.3 tolerance on T-score, there were no cases diagnosed as osteoporosis by DXA that were defined as normal by REMS. The REMS intra-operator CV was 0.51% for the lumbar spine and 1.08% for the femoral neck. The REMS inter-operator CV was 1.43% for the lumbar spine and 1.93% for the femoral neck. CONCLUSION: The REMS approach had high accuracy for the diagnosis of osteoporosis in comparison with DXA in adult women. According to our results, this new technology has shown to be a promising alternative for populations without access to DXA densitometry.

RESUMO

CONTEXT: The effects of PTH deprivation on bone are still unclear. Our objective was to report the characteristics of patients with postsurgical hypoparathyroidism (PsH) at a specialized outpatient service and correlate their trabecular bone score (TBS) values to clinical, densitometric, and laboratory findings. A secondary objective was to evaluate the fracture rates and look for associations between these events and the collected data. RESULTS: Eighty-two patients were enrolled, of whom 70 (85.4%) were female and 17 (20.7%) had type 2 diabetes mellitus (T2DM). The median body mass index (BMI) was 27.7 kg/m2 and the median age was 59 years. Of 68 dual-energy x-ray absorptiometry (DXA) scans obtained, osteopenia and osteoporosis were present in 32.4% and 2.9%, respectively. In all, 62 lumbar scans were analyzed by using TBS. The mean TBS value (±SD) was 1.386 ± 0.140, and 32.2% of the results were <1.310. TBS values correlated negatively with BMI (mainly > 30 kg/m2), age (mainly > 60 years), and glycemia, whereas abnormal TBS correlated with osteopenia, T2DM, low-impact fracture, and menopause. Six female patients had low-impact fractures, which were associated with a lower TBS (1.178 ± 0.065 vs. 1.404 ± 0.130 in the group without fractures; P < 0.001), older age, higher BMI, impaired renal function, abnormal glycemia, and osteopenia. CONCLUSION: The findings suggests that known risk factors for bone loss compromise the bone microarchitecture of individuals with PsH, regardless of DXA results. Menopausal women with PsH and older patients with PsH who have osteopenia, a higher BMI, or T2DM may be candidates for a more detailed assessment by using, for example, TBS.
