RESUMO

AIMS: To investigate the efficacy and safety of ultra-rapid lispro (URLi) versus insulin lispro in predominantly Chinese patients with type 1 diabetes (T1D) in a prospective, randomized, double-blind, treat-to-target, phase 3 study. MATERIALS AND METHODS: Following a lead-in period, during which insulin glargine U-100 or insulin degludec U-100 was optimized, patients were randomly assigned (1:1) to URLi (n = 176) or insulin lispro (n = 178). The primary objective was to test the noninferiority of URLi to insulin lispro in glycaemic control (noninferiority margin = 0.4% for glycated haemoglobin [HbA1c] change from baseline to week 26), with testing for the superiority of URLi to insulin lispro with regard to 1- and 2-hour postprandial glucose (PPG) excursions during a mixed-meal tolerance test and HbA1c change at week 26 as the multiplicity-adjusted objectives. RESULTS: From baseline to week 26, HbA1c decreased by 0.21% and 0.28% with URLi and insulin lispro, respectively, with a least squares mean treatment difference of 0.07% (95% confidence interval -0.11 to 0.24; P = 0.467). URLi demonstrated smaller 1- and 2-hour PPG excursions at week 26 with least squares mean treatment differences of -1.0 mmol/L (-17.8 mg/dL) and -1.4 mmol/L (-25.5 mg/dL), respectively (p < 0.005 for both) versus insulin lispro. The safety profiles of URLi and insulin lispro were similar. CONCLUSIONS: In this study, URLi administered in a basal-bolus regimen demonstrated superiority to insulin lispro in controlling PPG excursions, with noninferiority of HbA1c control in predominantly Chinese patients with T1D.

RESUMO

Type 2 diabetes mellitus (DM2) is a multimorbidity, long-term condition, and one of the worldwide leading causes of chronic kidney disease (CKD) -a silent disease, usually detected when non-reversible renal damage have already occurred. New strategies and more effective laboratory methods are needed for more opportune diagnosis of DM2-CKD. This study comprises clinical parameters and nuclear magnetic resonance (NMR)-based urine metabolomics data from 60 individuals (20-65 years old, 67.7% females), sorted in 5 experimental groups (healthy subjects; diabetic patients without any clinical sign of CKD; and patients with mild, moderate, and severe DM2-CKD), according to KDIGO. DM2-CKD produces a continuous variation of the urine metabolome, characterized by an increase/decrement of a group of metabolites that can be used to monitor CKD progression (trigonelline, hippurate, phenylalanine, glycolate, dimethylamine, alanine, 2-hydroxybutyrate, lactate, and citrate). NMR profiles were used to obtain a statistical model, based on partial least squares analysis (PLS-DA) to discriminate among groups. The PLS-DA model yielded good validation parameters (sensitivity, specificity, and area under the curve (AUC) of the receiver operating characteristic curve (ROC) plot: 0.692, 0.778 and 0.912, respectively) and, thus, it can differentiate between subjects with DM2-CKD in early stages, from subjects with a mild or severe condition. This metabolic signature exhibits a molecular variation associated to DM2-CKD, and data suggests it can be used to predict risk of DM2-CKD in patients without clinical signs of renal disease, offering a new alternative to current diagnosis methods.

RESUMO

PURPOSE: Osteoporosis in pregnancy is an uncommon disease and there is little information regarding its pathogenesis and its effects on the skeleton. This review aims to describe changes in mineral metabolism during pregnancy and lactation as well as their clinical impact. METHODS: We performed a narrative review of the literature using the PubMed and Google Scholar databases for articles published from 1955 to 2021. RESULTS: Mineral metabolism in the mother must adapt to the demand created by the fetus and the placenta, which together absorb calcium and other minerals from the mother to mineralize the developing fetal skeleton; analyses of iliac bone biopsies at the beginning and end of pregnancy have shown that pregnancy significantly modifies maternal bone status. The greatest demand for calcium for the maternal skeleton occurs during lactation; women who breastfeed have an even greater loss of calcium to produce milk. However, it is controversial whether breastfeeding can increase the risk of osteoporotic fractures, and the possible mechanism is considerably complicated. Osteoporosis in pregnancy is an uncommon disease characterized by the occurrence of fragility fractures, most commonly in the vertebral column, in the third trimester of pregnancy, or early postpartum. The pathogenesis of PLO remains unclear owing to its rarity; DXA provides a sensitive and specific method for diagnosing osteoporosis by measuring BMD, one of the parameters that allow a better understanding of fracture risk. One limitation is the controversy in using radiation in pregnant women and the risk to the embryo/fetus; a safe alternative can be MRI. CONCLUSION: Pregnancy and lactation alter the maternal bone status; without a balance in metabolism, this may cause an increased risk of fracture due to changes in BMD. There is little information on BMD during pregnancy; more clinical studies are required to elucidate if this represents a risk factor for osteoporosis.

RESUMO

Resumen OBJETIVO: Establecer si existe asociación entre el hiperparatiroidismo secundario a una deficiencia de vitamina D en el embarazo y la frecuencia de preeclampsia. MATERIALES Y MÉTODOS: Estudio de casos y controles, prospectivo y longitudinal efectuado en pacientes con y sin preeclampsia que entre el 1 de enero y el 30 de junio del 2021 acudieron al Hospital Universitario de la Universidad Autónoma de Nuevo León para la atención del parto. Criterios de inclusión: pacientes embarazadas con diagnóstico de preeclampsia en el último trimestre de la gestación con tensión arterial igual o mayor a 140-90 mmHg y proteinuria igual o mayor a 30 mg/dL. Para el grupo control: embarazadas sanas, sin diagnóstico de preeclampsia en el último trimestre de la gestación. Criterios de exclusión: tabaquismo, alcoholismo y drogadicción y quienes no aceptaron entrar al estudio o tuvieran diagnóstico de enfermedades médicas crónicas. RESULTADOS: Se estudiaron 90 pacientes divididas en dos grupos: con preeclampsia (n = 45) y sin ésta (control, n = 45). Se encontró una relación entre la deficiencia de vitamina D, la hipocalcemia y la preeclampsia; no así entre la paratohormona y la preeclampsia en los rangos internacionales de la primera. La preeclampsia se encontró con mayor frecuencia en pacientes de 12 a 15 años. CONCLUSIONES: El hiperparatiroidismo secundario a la deficiencia de vitamina D en el embarazo no se observó en pacientes con preeclampsia, quienes sí la padecieron tuvieron concentraciones de paratohormona en límites normales. Se encontró una relación entre la deficiencia de vitamina D, la hipocalcemia y la preeclampsia.


Abstract OBJECTIVE: To establish whether there is an association between hyperparathyroidism secondary to vitamin D deficiency in pregnancy and the frequency of preeclampsia. MATERIALSAND METHODS: Case-control, prospective, longitudinal study performed in patients with and without preeclampsia who between January 1 and June 30, 2021 attended the Hospital Universitario of the Universidad Autónoma de Nuevo Leon for delivery care. Inclusion criteria: pregnant patients with a diagnosis of preeclampsia in the last trimester of gestation with blood pressure equal to or greater than 140-90 mmHg and proteinuria equal to or greater than 30 mg/dL. For the control group: healthy pregnant women without a diagnosis of preeclampsia in the last trimester of gestation. Exclusion criteria: smoking, alcoholism and drug addiction and those who did not agree to enter the study or had a diagnosis of chronic medical diseases. RESULTS: We studied 90 patients divided into two groups: with preeclampsia (n = 45) and without preeclampsia (control, n = 45). A relationship was found between vitamin D deficiency, hypocalcemia, and preeclampsia; a relationship was not found between parathormone and preeclampsia in the international parathormone ranges. Preeclampsia was found more frequently in patients aged 12 to 15 years. CONCLUSIONS: Hyperparathyroidism secondary to vitamin D deficiency in pregnancy was not observed in patients with preeclampsia; those who had it had parathormone concentrations in normal limits. A relationship was found between vitamin D deficiency, hypocalcemia, and preeclampsia.

RESUMO

Los métodos de diagnóstico actuales son poco sensibles para detectar las etapas iniciales de la nefropatía diabética tipo 2. En este trabajo se hace una revisión de estudios de aproximación metabolómica para la identificación de biomarcadores de esta enfermedad con potencialidad para diferenciar entre etapas tempranas, evaluar y direccionar el tratamiento y coadyuvar a ralentizar el daño renal. Utilizando bases de datos públicas (Pubmed y Google Scholar) y privadas (Scopus y Web of Knowledge), se realizó una búsqueda sistemática de la información que se ha publicado de metabolómica de la nefropatía diabética en distintos bioespecímenes (orina, suero, plasma y sangre). Posteriormente, se utilizó el programa MetaboAnalyst 4.0 para evidenciar las vías metabólicas que están asociadas con estos metabolitos. Con los datos de la literatura se identificaron grupos de metabolitos potenciales para la monitorización de la nefropatía diabética. Destacan en la orina: el óxido-3-hidroxiisovalerato, TMAO, aconitato y citrato y derivados del hidroxipropionato; en el suero: el citrato, la creatinina, la arginina y sus derivados; y en el plasma: aminoácidos como histidina, metionina y arginina. Utilizando el programa MetaboAnalyst 4.0 se detectaron las rutas metabólicas que están relacionadas con estos metabolitos. La búsqueda de biomarcadores relacionados con la progresión de la nefropatía diabética junto con estrategias analíticas para su detección y cuantificación son el punto de partida para el diseño de nuevos métodos de análisis químico-clínico. La correlación con la disfunción de vías metabólicas podría ser utilizada para la evaluación integral del tratamiento y seguimiento clínico de este padecimiento


Current diagnostic methods are not very sensitive to detect the initial stages diabetic nephropathy of type 2. In this work, a review of metabolomic approximation studies for the identification of biomarkers of this disease with potential to differentiate between early stages, evaluate and direct treatment and help slow kidney damage. Using public (Pubmed and Google Scholar) and private (Scopus and Web of Knowledge) databases, a systematic search of the information published related to metabolomics of diabetic nephropathy in different biospecimens (urine, serum, plasma and blood) was made. Later, the MetaboAnalyst 4.0 software was used to identify the metabolic pathways associated with these metabolites. Groups of potential metabolites were identified for monitoring diabetic nephropathy with the available literature data. In the urine, oxide-3-hydroxyisovalerate, TMAO, aconite and citrate and hydroxypropionate derivatives are highlighted; meanwhile, in the serum: citrate, creatinine, arginine and its derivatives; and in the plasma: amino acids such as histidine, methionine and arginine has a potential contribution. Using MetaboAnalyst 4.0 the metabolic pathways related to these metabolites were related. The search for biomarkers to measure the progression of diabetic nephropathy, together with analytical strategies for their detection and quantification, are the starting point for designing new methods of clinical chemistry analysis. The association between the metabolic pathway dysfunction could be useful for the overall assessment of the treatment and clinical follow-up of this disease

RESUMO

AIM: To compare the effect of liraglutide or placebo added on to sodium-glucose co-transporter-2 inhibitor (SGLT2i) ± metformin on glycaemic control in patients with type 2 diabetes. MATERIALS AND METHODS: Patients with type 2 diabetes on a stable SGLT2i dose ± metformin (with HbA1c 7.0%-9.5% and body mass index [BMI] ≥ 20 kg/m2 ) were randomized 2:1 to add-on liraglutide 1.8 mg/day or placebo in this parallel, double-blind, multinational trial. Primary and confirmatory secondary endpoints were changes in HbA1c and body weight from baseline to week 26, respectively. The proportions of patients achieving HbA1c (<7.0%) targets and safety events after week 26 were also assessed. RESULTS: Of 303 patients randomized (one in error), 280 completed treatment. Mean changes in HbA1c from baseline to week 26 with liraglutide (n = 202) and placebo (n = 100) were - 0.98% and - 0.30%, respectively (estimated treatment difference [ETD]: -0.68% [95% CI: -0.89, -0.48]; P < 0.001). Mean body weight changes from baseline were - 2.81 versus -1.99 kg, respectively (ETD: -0.82 kg [95% CI: -1.73, 0.09]; P = 0.077); 51.8% of liraglutide-treated patients achieved HbA1c < 7.0% versus 23.2% receiving placebo (odds ratio: 5.1 [95% CI: 2.67, 9.87]; P < 0.001). More patients treated with liraglutide reported ≥1 treatment-emergent adverse events (66.3%) versus placebo (47.0%). CONCLUSIONS: Liraglutide significantly improved glycaemic control compared with placebo in patients with type 2 diabetes, insufficiently controlled with SGLT2is with/without metformin, with no unexpected safety findings.

RESUMO

Objective: The purpose of this study is to establish the prevalence of vitamin D deficiency and their newborns and analyze the risk factors related to this deficiency. Methods: This is an observational, transversal, and prospective study. It included 191 puerperal women and their full-term newborns. Serum 25 hydroxyvitamin D values were analyzes by enzyme immunoassay. Results: 61% of the puerperal presented deficiency and 26% insufficiency of vitamin D. In the newborn group 98% showed deficiency and 66% of them presented severe deficiency. There is a positive correlation between the values of vitamin D in mothers and their newborns (r2 = 0.173 ng/ml; p = 0.017). The lowest levels were in autumn. (15.75 ng/mL mothers, 6 ng/mL newborns). There was no correlation between vitamin D levels in mothers and their dietary intake, maternal skin type, sun time exposure and prenatal body mass index. Conclusions: This is the first study that shows the existence of a high deficiency of vitamin D in Mexican mothers and their newborns.

RESUMO

Introducción. La artritis reumatoide (AR) tiene un efecto indirecto en la composición corporal. El índice de masa corporal (IMC) no se considera un predictor válido de la grasa corporal en pacientes con AR. Objetivo. Evaluar el IMC para identificar la obesidad mediante absorciometría dual por rayos X (DEXA) en pacientes con AR bien controlados. Métodos. Estudio observacional, transversal, descriptivo y analítico. Se utilizaron 3 definiciones de obesidad por DEXA:>35% de grasa total, >40% de grasa total y obesidad central>35%. Resultados. Se incluyó a 101 pacientes. Se encontró un IMC de 24kg/m2 para obesidad >35% con una sensibilidad del 90% y una especificidad del 75% (área bajo la curva [AUC] 0,917), un IMC de 25kg/m2 para obesidad >40% con una sensibilidad del 86% y una especificidad del 39% (AUC 0,822) y un IMC de 22kg/m2 para 35% de la grasa central con una sensibilidad de 97% y una especificidad del 84% (AUC 0,951). Conclusión. Existe un subdiagnóstico de obesidad con el uso de los valores de tradicionales de IMC en pacientes con AR bien controlados (AU)


Background. Rheumatoid arthritis (RA) has an indirect effect on body composition. Body mass index (BMI) is not a valid predictor of body fat in RA patients. Objective. To evaluate the accuracy of BMI in identifying obesity diagnosed according to dual energy X-ray absorptiometry (DXA) in well-controlled RA patients. Methods. An observational, cross-sectional, descriptive, analytical study. We used 3 different cutoffs for obesity as determined by DXA: >35% total fat, >40% total fat, and >35% central fat mass (central obesity). Results. One hundred one patients were included. We found that 35% total fat corresponded to a BMI of 24kg/m2, with a sensitivity of 90% and specificity of 75% (area under the curve [AUC] 0.917); 40% total fat to a BMI of 25kg/m2, with a sensitivity of 86% and specificity of 39% (AUC 0.822); and 35% central fat mass to a BMI of 22kg/m2, with a sensitivity of 97% and specificity of 84% (AUC 0.951). Conclusion. Obesity according to DXA was underdiagnosed when the classic BMI cutoffs were used in well-controlled RA patients (AU)

RESUMO

We present final results of a study comparing teriparatide 20 µg every day (QD) with risedronate 35 mg once per week (QW) started within 2 weeks after surgery for a pertrochanteric hip fracture. Patients with BMD T-score ≤ -2.0 and 25OHD ≥9.2 ng/mL were randomized to receive 26-week double-dummy treatment plus calcium and vitamin D, followed by 52-week open-label treatment with the same assigned active drug. Primary endpoint was change from baseline in lumbar spine (LS) BMD at 78 weeks. Secondary and exploratory endpoints were change in BMD at the proximal femur, function, hip pain (Charnley score and 100 mm Visual Analog Scale [VAS]), quality of life (Short Form-36), radiology outcomes, and safety. Data were analyzed with mixed models for repeated measures (MMRM) and logistic regression. Totally, 224 patients were randomized; 171 (teriparatide: 86) contributed to the efficacy analyses (mean ± SD age: 77 ± 7.7 years, 77% females). Mean baseline LS, femoral neck (FN), and total hip (TH) T-scores were -2.16, -2.63, and -2.51, respectively. At 78 weeks, BMD increased significantly more with teriparatide compared to risedronate at the LS (+11.08% versus +6.45%; p < 0.001) and FN (+1.96% versus -1.19%; p = 0.003), with no significant between-group difference in TH BMD. Timed up-and-go (TUG) test was significantly faster with teriparatide at 6, 12, 18, and 26 weeks (differences: -3.2 to -5.9 s; p = 0.045 for overall difference). Hip pain during TUG test by 100 mm VAS was significantly lower with teriparatide at 18 weeks (adjusted difference: -11.3 mm, p = 0.033; -10.0 and -9.3 mm at 12 and 26 weeks, respectively; p = 0.079 for overall difference). Other secondary and exploratory outcomes were not different. Teriparatide group showed two new hip fractures versus seven with risedronate (p = 0.171) and more frequent hypercalcemia and hyperuricemia. In conclusion, 78-week treatment with teriparatide showed significantly greater increases in LS and FN BMD, less pain, and a faster TUG test versus risedronate. © 2016 American Society for Bone and Mineral Research.

RESUMO

BACKGROUND: Osteoporosis drugs might affect fracture-healing. We therefore studied the effects of teriparatide in comparison with risedronate on recovery after pertrochanteric hip fractures. METHODS: The study was a randomized, multicenter, active-controlled, 78-week trial comparing teriparatide (20 µg/day) with risedronate (35 mg/week) initiated within 2 weeks after fixation of a low-trauma pertrochanteric hip fracture (AO/OTA 31-A1 or 31-A2). The main inclusion criteria were a bone mineral density T-score of ≤-2.0 and 25-OH-vitamin D of ≥9.2 ng/mL. During the first 26 weeks, patients received study medication with oral or injectable placebo plus calcium and vitamin D in a double-blinded fashion. Secondary (Timed Up-and-Go [TUG] test, hip pain, Short Form [SF]-36 health status, and safety) and exploratory (radiographic outcomes and ability to walk) 26-week end points are reported. RESULTS: Of the 224 patients who were randomized, 171 (86 teriparatide, 85 risedronate) were included in the analysis. The mean age was 77 ± 8 years, 77% were female, and 26% had a prior history of low-trauma fracture. The teriparatide group completed the TUG test in a shorter time at 6, 12, 18, and 26 weeks (differences of -5.7, -4.4, -3.1, and -3.1 seconds, respectively; p = 0.021 for the overall difference). They also reported less pain on a visual analog scale immediately after the TUG test at 12 and 18 weeks (adjusted absolute differences of 10.6 and 11.9 mm, respectively; p < 0.05). There were no significant between-group differences in the SF-36 score, Charnley hip pain score, ability to walk, or use of walking aids during follow-up. Radiographic healing at 6, 12, and 26 weeks, mechanical failure of the implant (teriparatide, 7; risedronate, 8), loss of reduction (teriparatide, 2; risedronate, 4), and nonunion (0 cases) were not significantly different. Mild hypercalcemia and hyperuricemia were more frequent with teriparatide. CONCLUSIONS: Teriparatide was associated with less pain and a shorter time to complete the TUG test between 6 and 26 weeks compared with risedronate. Other fracture-recovery outcomes were similar. The results should be interpreted with caution as these were secondary end points. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

IMPORTANCE: Achieving glycemic control remains a challenge for patients with type 2 diabetes, even with insulin therapy. OBJECTIVE: To assess whether a fixed ratio of insulin degludec/liraglutide was noninferior to continued titration of insulin glargine in patients with uncontrolled type 2 diabetes treated with insulin glargine and metformin. DESIGN, SETTING, AND PARTICIPANTS: Phase 3, multinational, multicenter, 26-week, randomized, open-label, 2-group, treat-to-target trial conducted at 75 centers in 10 countries from September 2013 to November 2014 among 557 patients with uncontrolled diabetes treated with glargine (20-50 U) and metformin (≥1500 mg/d) with glycated hemoglobin (HbA1c) levels of 7% to 10% and a body mass index of 40 or lower. INTERVENTIONS: 1:1 randomization to degludec/liraglutide (n = 278; maximum dose, 50 U of degludec/1.8 mg of liraglutide) or glargine (n = 279; no maximum dose), with twice-weekly titration to a glucose target of 72 to 90 mg/dL. MAIN OUTCOMES AND MEASURES: Primary outcome measure was change in HbA1c level after 26 weeks, with a noninferiority margin of 0.3% (upper bound of 95% CI, <0.3%). If noninferiority of degludec/liraglutide was achieved, secondary end points were tested for statistical superiority and included change in HbA1c level, change in body weight, and rate of confirmed hypoglycemic episodes. RESULTS: Among 557 randomized patients (mean: age, 58.8 years; women, 49.7%), 92.5% of patients completed the trial and provided data at 26 weeks. Baseline HbA1c level was 8.4% for the degludec/liraglutide group and 8.2% for the glargine group. HbA1c level reduction was greater with degludec/liraglutide vs glargine (-1.81% for the degludec/liraglutide group vs -1.13% for the glargine group; estimated treatment difference [ETD], -0.59% [95% CI, -0.74% to -0.45%]), meeting criteria for noninferiority (P < .001), and also meeting criteria for statistical superiority (P < .001). Treatment with degludec/liraglutide was also associated with weight loss compared with weight gain with glargine (-1.4 kg for degludec/liraglutide vs 1.8 kg for glargine; ETD, -3.20 kg [95% CI, -3.77 to -2.64],P < .001) and fewer confirmed hypoglycemic episodes (episodes/patient-year exposure, 2.23 for degludec/liraglutide vs 5.05 for glargine; estimated rate ratio, 0.43 [95% CI, 0.30 to 0.61],P < .001). Overall and serious adverse event rates were similar in the 2 groups, except for more nonserious gastrointestinal adverse events reported with degludec/liraglutide (adverse events, 79 for degludec/liraglutide vs 18 for glargine). CONCLUSIONS AND RELEVANCE: Among patients with uncontrolled type 2 diabetes taking glargine and metformin, treatment with degludec/liraglutide compared with up-titration of glargine resulted in noninferior HbA1c levels, with secondary analyses indicating greater HbA1c level reduction after 26 weeks of treatment. Further studies are needed to assess longer-term efficacy and safety. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01952145.

RESUMO

INTRODUCTION: There are few studies integrating the common causes of osteoporosis and obesity (disorders of body composition). A first step is to investigate correlations between their biological phenotypes to determine their common integrative physiology. OBJECTIVE: To correlate the variation of bone mineral density with phenotypes of body composition and biomarkers of bone physiology, insulin-glucose axis, and adipose tissue. METHODS: Cross-sectional study of 75 women (aged 18-45 years). MEASUREMENTS: Body mass index, waist, fat mass, lean mass (dual-energy X-ray absorptiometry), glucose, insulin, osteocalcin, leptin, tumor necrosis factor alpha. STATISTICAL ANALYSIS: multivariate general linear model, SPSS v.22, p<0.05. RESULTS: Age: 32.08±7.33. Bone mineral content multivariate general linear model 1 with two phenotypes excluded (glucose, insulin): osteocalcin (ß=-0.228, p=0.011), lean mass (ß=0.606, p=0.001) and fat mass (ß=1.237, p=0.001) in 62.0%. The bone mineral density multivariate general linear model 2 with three phenotypes excluded (body mass index, glucose, tumor necrosis factor alpha): insulin (ß=0.250, p=0.024), osteocalcin (ß=-0.362, p=0.001), lean mass (ß=0.512, p=0.001) and fat mass (ß=0.701, p=0.001) in 46.3%. CONCLUSIONS: Results show that body composition with an increased lean mass is beneficial to bone. This study reaffirms the importance of performing regular exercise to prevent muscle loss.

RESUMO

BACKGROUND: Osteoporosis affects 1 in 3 postmenopausal women and is associated with significant morbidity and mortality. The utility of bisphosphonates is often affected by lack of attachment and acceptance of treatment. OBJECTIVE: To analyze the impact of biofeedback in the adherence to once-monthly oral ibandronate treatment. PATIENTS AND METHOD: We designed an open-label, prospective, randomized, multicenter clinical study to investigate the impact of biofeedback with bone turnover markers on adherence to once-monthly oral ibandronate treatment in 781 Mexican and Chilean patients with postmenopausal osteoporosis (BOHEMIA study). They were enrolled at 25 centers in Mexico (700 patients) and 24 centers in Chile (81 patients). All patients received once-monthly oral ibandronate 150 mg for 6 months. Patients without previous bisphosphonate treatment, previous bisphosphonate users, or current bisphosphonate users were included. Patients were randomly divided into two arms at baseline, either to receive biofeedback or not. RESULTS: A statistically significant improvement in adherence was found in patients who received biofeedback when compared with those who did not (98.8 to 99.8% [95% CI] and 95.5 to 97.5%, respectively [p < 0.001]). CONCLUSIONS: Even though biofeedback with bone turnover markers was associated with a significantly greater adherence, it was not great enough to recommend biofeedback as a strategy to achieve optimal adherence. Once-monthly ibandronate by itself can achieve an adequate therapeutic adherence.

RESUMO

OBJECTIVE: To compare the efficacy of liraglutide monotherapy with glimepiride monotherapy in subjects with DM2 inadequately controlled by previous treatment of diet/exercise or oral antidiabetic drug. METHODS: A 52-week, double-blinded, active-controlled, parallel-group, multi-centre, prospective trial, involving 746 subjects was conducted in the USA and Mexico. In Mexico, 171 subjects were rando-mised (1:1:1) to once daily liraglutide (either 1.2, or 1.8 mg/day injected subcutaneously) or glimepiride (8 mg/day orally). RESULTS: Hb1Ac reduced by 0.64%, 1.31% and 0.30% with glimepiride, liraglutide 1.8 mg and 1.2 mg, respectively. Body weight decreased with both liraglutide doses while a weight gain of 0.94 kg was observed with glimepiride. FPG reduced by 27.9 mg/dL with liraglutide 1.8 mg, whereas a FPG increase of 9.54 mg/dL was shown with glimepiride. No major hypoglycaemic episodes were reported in this trial. CONCLUSIONS: in Mexican subjects with DM2, liraglutide monotherapy can provide greater reduction in HbA1c, weight loss and lower risk of hypoglycaemia in comparison with glimepiride.

RESUMO

Animal experiments show a dramatic improvement in skeletal repair by teriparatide. We tested the hypothesis that recombinant teriparatide, at the 20 microg dose normally used for osteoporosis treatment or higher, would accelerate fracture repair in humans. Postmenopausal women (45 to 85 years of age) who had sustained a dorsally angulated distal radial fracture in need of closed reduction but no surgery were randomly assigned to 8 weeks of once-daily injections of placebo (n = 34) or teriparatide 20 microg (n = 34) or teriparatide 40 microg (n = 34) within 10 days of fracture. Hypotheses were tested sequentially, beginning with the teriparatide 40 microg versus placebo comparison, using a gatekeeping strategy. The estimated median time from fracture to first radiographic evidence of complete cortical bridging in three of four cortices was 9.1, 7.4, and 8.8 weeks for placebo and teriparatide 20 microg and 40 microg, respectively (overall p = .015). There was no significant difference between the teriparatide 40 microg versus placebo groups (p = .523). In post hoc analyses, there was no significant difference between teriparatide 40 microg versus 20 microg (p = .053); however, the time to healing was shorter in teriparatide 20 microg than placebo (p = .006). The primary hypothesis that teriparatide 40 microg would shorten the time to cortical bridging was not supported. The shortened time to healing for teriparatide 20 microg compared with placebo still may suggest that fracture repair can be accelerated by teriparatide, but this result should be interpreted with caution and warrants further study.

RESUMO

CONTEXT: Treatment of osteoporosis with an anabolic agent, teriparatide [human PTH 1-34 (TPTD)], is effective in reducing incident fractures, but patient resistance to daily sc injections has limited its use. A novel transdermal patch, providing a rapid, pulse delivery of TPTD, may provide a desirable alternative. OBJECTIVE: The aim of the study was to determine the safety and efficacy of a novel transdermal TPTD patch compared to placebo patch and sc TPTD 20-microg injection in postmenopausal women with osteoporosis. DESIGN: Our study consisted of 6-month, randomized, placebo-controlled, positive control, multidose daily administration. PATIENTS: We enrolled 165 postmenopausal women (mean age, 64 yr) with osteoporosis. INTERVENTIONS: A TPTD patch with a 20-, 30-, or 40-microg dose or a placebo patch was self-administered daily for 30-min wear time, or 20 microg of TPTD was injected daily. OUTCOMES: The primary efficacy measure was mean percentage change in lumbar spine bone mineral density (BMD) from baseline at 6 months. RESULTS: TPTD delivered by transdermal patch significantly increased lumbar spine BMD vs. placebo patch in a dose-dependent manner at 6 months (P < 0.001). TPTD 40-microg patch increased total hip BMD compared to both placebo patch and TPTD injection (P < 0.05). Bone turnover markers (procollagen type I N-terminal propeptide and C-terminal cross-linked telopeptide of type I collagen) increased from baseline in a dose-dependent manner in all treatment groups and were all significantly different from placebo patch (P < 0.001). All treatments were well tolerated, and no prolonged hypercalcemia was observed. CONCLUSION: Transdermal patch delivery of TPTD in postmenopausal women with osteoporosis for 6 months is safe and effective in increasing lumbar spine and total hip BMD.

RESUMO

Osteoporosis is recognized worldwide as a major public health problem since many decades ago, mainly due to the cost of treatment for related fragility fractures. Fortunately, WHO has provided new strategies for identifying populations with a high ten-year fracture risk, which together with increasingly sensitive diagnostic methods make it feasible for decision makers in this field to design cost effective fracture prevention strategies. These strategies are aimed at preventing falls and improving bone strength and therefore diminishing the prevalence and incidence of new or recurrent osteoporosis related fractures. Herein we review the content of these new strategies, and the medical treatments available, as well as their efficacy in the Mexican context. Several countries are now reporting a decreasing incidence and prevalence of osteoporosis related fractures, after 30 years of clinical and population-based interventions. Mexico has several effective anti-fracture drug treatments available. Such drugs can be classified according to the mechanism that makes them effective as: 1) antidestructive or anticatabolic, 2) bone forming or anabolic, and 3) those with both actions or mixed drugs. The authors argue that treatment strategies that use drugs to strengthen bone tissue must assure normal mineralization of the already formed, remnant bone tissue and/or the newly formed bone tissue in order to encourage biochemical outcomes like formation of mature hydroxyapatite crystals with complete biomechanical and biochemical properties and therefore long term benefits. The present review includes some perspectives that will surely enhance osteoporosis management in the near future and which will bring about a decrease in the impact of the problems in Mexico.
