RESUMEN
AIM: To investigate the impact of pituitary surgery on glucose metabolism and to identify predictors of remission of diabetes after pituitary surgery in patients with acromegaly. METHODS: A national multicenter retrospective study of patients with acromegaly undergoing transsphenoidal surgery for the first time at 33 tertiary Spanish hospitals (ACRO-SPAIN study) was performed. Surgical remission of acromegaly was evaluated according to the 2000 and 2010 criteria. RESULTS: A total of 604 acromegaly patients were included in the study with a total median follow up of 91 months (interquartile range [IQR] 45-163). At the acromegaly diagnosis, 23.8% of the patients had diabetes mellitus (DM) with a median glycated hemoglobin (HbA1c) of 6.9% (IQR 6.4-7.9) [51.9 mmol/mol (IQR 46.4-62.8)]. In the multivariate analysis, older age (odds ratio [OR] 1.02, 95% CI 1.00-1.05), dyslipidemia (OR 5.25, 95% CI 2.81 to 9.79), arthropathy (OR 1.39, 95% CI 2.82 to 9.79), and higher IGF-I levels (OR 1.30, 95% CI 1.05 to 1.60) were associated with a greater prevalence of DM. At the last follow-up visit after surgery, 21.1% of the DM patients (56.7% of them with surgical remission of acromegaly) experienced diabetes remission. The cure rate of DM was more common in older patients (hazard ratio [HR] 1.77, 95% CI 1.31 to 2.43), when surgical cure was achieved (HR 2.10, 95% CI 1.01 to 4.37) and when anterior pituitary function was not affected after surgery (HR 3.38, 95% CI 1.17 to 9.75). CONCLUSION: Glucose metabolism improved in patients with acromegaly after surgery and 21% of the diabetic patients experienced diabetes remission; being more frequent in patients of older age, and those who experienced surgical cure and those with preserved anterior pituitary function after surgery.
RESUMEN
BACKGROUND/OBJECTIVES: Although vascular endothelial growth factor b (VEGFb) might have an impact on the development of obesity, diabetes and related disorders, the possible relationship between VEGFb serum levels and the incidence of these metabolic complications in humans is still unknown. The aim of our study was to evaluate the association between VEGFb serum levels and the new-onset of metabolic syndrome (MS) and its components in the Spanish adult population after 7.5 years of follow-up. SUBJECTS/METHODS: A total of 908 subjects from the Di@bet.es cohort study without MS at cross-sectional stage according to International Diabetes Federation (IDF) or Adult Treatment Panel III (ATP-III) criteria were included. Additionally, five sub-populations were grouped according to the absence of each MS component at baseline. Socio-demographic, anthropometric and clinical data were recorded. The Short Form of International Physical Activity Questionnaire (SF-IPAQ) was used to estimate physical activity. A fasting blood extraction and an oral glucose tolerance test were performed. Serum determinations of glucose, lipids, hsCRP and insulin were made. VEGFb levels were determined and categorized according to the 75th percentile of the variable. New cases of MS and its components were defined according to ATPIII and IDF criteria. RESULTS: A total of 181 or 146 people developed MS defined by IDF or ATP-III criteria respectively. Serum triglyceride levels, hs-CRP and systolic blood pressure at the baseline study were significantly different according to the VEGFb categories. Adjusted logistic regression analysis showed that the likelihood of developing MS and abdominal obesity was statistically reduced in subjects included in the higher VEGFb category. CONCLUSION: Low serum levels of VEGFb may be considered as early indicators of incident MS and abdominal obesity in the Spanish adult population free of MS, independently of other important predictor variables.

INTRODUCTION: there are few data on the prevalence of vitamin D deficiency in patients with inflammatory bowel disease (IBD) in Spain. A deficiency could be associated with a worse course of the disease. AIM: to determine the prevalence of 25-hydroxyvitamin D (25OHD) deficiency in a cohort of outpatients with IBD and assess its association with clinical and biological activity, quality of life and psychological symptoms. METHODS: a cross-sectional, single-center observational study was performed. The study variables were obtained via clinical interviews, medical chart review and validated questionnaires (Hospital Anxiety and Depression Scale and Short Quality of Life in Inflammatory Bowel Disease Questionnaire). 25OHD was measured in the same laboratory by an electro-chemiluminescence immunoassay. RESULTS: the study included 224 patients. The prevalence of vitamin D deficiency in Crohn's disease and ulcerative colitis was 33.3% and 20.3%, respectively. In Crohn's disease, vitamin D deficiency was associated with a higher clinical activity (p < 0.001) and a higher concentration of fecal calprotectin (p = 0.01). In ulcerative colitis, it was associated with clinical activity (p < 0.001), the use of steroids during the last six months (p = 0.001) and hospital admission during the previous year (p = 0.003). A sub-analysis of 149 patients failed to detect an association between vitamin D and quality of life or the scores of the Hospital Anxiety and Depression Scale. CONCLUSIONS: vitamin D deficiency is common in patients with inflammatory bowel disease. An association was found between vitamin D concentration and clinical activity indexes, as well as fecal calprotectin levels in Crohn's disease.

INTRODUCTION: Sunlight exposure is the main source of vitaminD. Our aim was to describe both sun exposure and sun protection behaviour in a series of patients with inflammatory bowel disease (IBD), and to study their potential association with vitaminD concentration. PATIENTS AND METHODS: A cross sectional, observational study. The clinical-demographic variables were obtained via clinical interviews and medical history review. The sunlight exposure assessment was carried out using the Sun Exposure Questionnaire and the concentration of 25-hydroxy vitaminD (25OHD) was measured by an electro-chemiluminescence immunoassay. Questionnaires were conducted on quality of life, physical activity, weekly vitaminD intake and sun protection behaviour. RESULTS: 149 patients were included. In 69% of patients, deficient or insufficient 25OHD values were recorded. 67% showed low sun exposure. A modest significant correlation was observed between the total score of the solar exposure questionnaire and the 25OHD concentration in the complete series (r=0.226, P=.006) and in the summer (r=0.274, P=.01). The sun protection behaviour questionnaire score did not influence the 25OHD concentration. In the multivariate analysis, only the presence of clinical activity was associated with low sun exposure (OR=3.23). DISCUSSION: Sun exposure according to the questionnaire used was low, was associated with the presence of clinical activity and was weakly correlated with serum 25OHD concentration. More studies are needed to explore the use of individual questionnaires for sun exposure and its relationship with vitaminD in patients with IBD.

Rathke's cleft cysts (RCC) are a common type of lesion found in the sellar or suprasellar area. They are usually monitored clinically, but in some cases, surgery may be required. However, their natural progression is not yet well understood, and the outcomes of surgery are uncertain. The objective of this study is to evaluate the natural history of Rathke's cleft cysts in patients who are clinically monitored without treatment, and to determine the outcomes of surgery and the incidence of recurrences over time. Design and patients: National multicentric study of patients diagnosed of Rathke's cleft cyst (RCC- Spain) from 2000 onwards and followed in 15 tertiary centers of Spain. A total of 177 patients diagnosed of RCC followed for 67.3 months (6-215) and 88 patients who underwent surgery, (81 patients underwent immediate surgery after diagnosis and 7 later for subsequent growth) followed for 68.8 months (3-235). Results: The cyst size remained stable or decreased in 73.5% (133) of the patients. Only 44 patients (24.3%) experienced a cyst increase and 9 of them (5.1%) experienced an increase greater than 3 mm. In most of the patients who underwent surgery headaches and visual alterations improved, recurrence was observed in 8 (9.1%) after a median time of 96 months, and no predictors of recurrence were discovered. Conclusions: Rathke's cleft cysts without initial compressive symptoms have a low probability of growth, so conservative management is recommended. Patients who undergo transsphenoidal surgery experience rapid clinical improvement, and recurrences are infrequent. However, they can occur after a long period of time, although no predictors of recurrence have been identified.

PURPOSE: To evaluate differences in clinical presentation and in surgical outcomes between growth hormone-secreting pituitary adenomas (GH-PAs) and GH and prolactin co-secreting pituitary adenomas (GH&PRL-PAs). METHODS: Multicenter retrospective study of 604 patients with acromegaly submitted to pituitary surgery. Patients were classified into two groups according to serum PRL levels at diagnosis and immunohistochemistry (IHC) for PRL: a) GH&PRL-PAs when PRL levels were above the upper limit of normal and IHC for GH and PRL was positive or PRL levels were >100ng/and PRL IHC was not available (n=130) and b) GH-PAs who did not meet the previously mentioned criteria (n=474). RESULTS: GH&PRL-PAs represented 21.5% (n=130) of patients with acromegaly. The mean age at diagnosis was lower in GH&PRL-PAs than in GH-PAs (P<0.001). GH&PRL-PAs were more frequently macroadenomas (90.6% vs. 77.4%, P=0.001) and tended to be more invasive (33.6% vs. 24.7%, P=0.057) than GH-PAs. Furthermore, they had presurgical hypopituitarism more frequently (OR 2.8, 95% CI 1.83-4.38). IGF-1 upper limit of normality (ULN) levels at diagnosis were lower in patients with GH&PRL-PAs (median 2.4 [IQR 1.73-3.29] vs. 2.7 [IQR 1.91-3.67], P=0.023). There were no differences in the immediate (41.1% vs 43.3%, P=0.659) or long-term post-surgical acromegaly biochemical cure rate (53.5% vs. 53.1%, P=0.936) between groups. However, there was a higher incidence of permanent arginine-vasopressin deficiency (AVP-D) (7.3% vs. 2.4%, P=0.011) in GH&PRL-PAs patients. CONCLUSIONS: GH&PRL-PAs are responsible for 20% of acromegaly cases. These tumors are more invasive, larger and cause hypopituitarism more frequently than GH-PAs and are diagnosed at an earlier age. The biochemical cure rate is similar between both groups, but patients with GH&PRL-PAs tend to develop permanent postsurgical AVP-D more frequently.
RESUMEN
The objective of the study was to evaluate the efficacy of second-line therapies in patients with acromegaly caused by a growth hormone (GH) and prolactin (PRL) co-secreting pituitary neuroendocrine tumor (GH&PRL-Pit-NET) compared to their efficacy in patients with acromegaly caused by a GH-secreting pituitary neuroendocrine tumor (GH-Pit-NET). This is a multicenter retrospective study of patients with acromegaly on treatment with pasireotide and/or pegvisomant. Patients were classified in two groups: GH&PRL-Pit-NETs when evidence of hyperprolactinemia and immunohistochemistry (IHC) for GH and PRL was positive or if PRL were >200 ng/dL regardless of the PRL-IHC and GH-Pit-NETs when the previously mentioned criteria were not met. A total of 28 cases with GH&PRL-Pit-NETs and 122 with GH-Pit-NETs met the inclusion criteria. GH&PRL-Pit-NETs presented at a younger age, caused hypopituitarism, and were invasive more frequently than GH-Pit-NETs. There were 124 patients treated with pegvisomant and 49 with pasireotide at any time. The efficacy of pegvisomant for IGF-1 normalization was of 81.5% and of pasireotide of 71.4%. No differences in IGF-1 control with pasireotide and with pegvisomant were observed between GH&PRL-Pit-NETs and GH-Pit-NETs. All GH&PRL-Pit-NET cases treated with pasireotide (n = 6) and 82.6% (n = 19/23) of the cases treated with pegvisomant normalized PRL levels. No differences in the rate of IGF-1 control between pegvisomant and pasireotide were detected in patients with GH&PRL-Pit-NETs (84.9% vs 66.7%, P = 0.178). We conclude that despite the more aggressive behavior of GH&PRL-Pit-NETs than GH-Pit-NETs, no differences in the rate of IGF-1 control with pegvisomant and pasireotide were observed between both groups, and both drugs have shown to be effective treatments to control IGF-1 and PRL hypersecretion in these tumors.

OBJECTIVE: Cognitive effects in acromegaly patients are poorly understood and the mechanisms involved are still unclear. The aim of this study was to evaluate the cognitive function, depression, and quality of life of acromegaly patients treated with pegvisomant versus somatostatin analogues (SRLs) and to analyze the effect of the different treatments on cognition and possible structural brain changes. METHODS: This cross-sectional study involved 23 acromegaly patients divided into two groups according to treatment modality: One group of 9 patients treated with pegvisomant and another group of 14 patients treated with SRLs. All participants underwent blood analysis, neuropsychological tests, depression tests, quality of life assessment, and 3-Tesla magnetic resonance imaging. RESULTS: We found no significant differences between groups in the neuropsychological tests, depression or quality of life; nor in the whole-brain cortical thickness. In the SRL group, the volume of the thalamus correlated positively with executive function, a correlation not found in the pegvisomant group. In addition, the pegvisomant group had significantly higher levels of insulin than the SRL group. CONCLUSIONS: In conclusion, in this pilot study, the type of pharmacological treatment in patients with acromegaly and good glycemic control did not influence the cognitive function and cortical brain thickness. However, pegvisomant could play a neuroprotective role on the thalamus that will have to be demonstrated with larger samples in future studies.

BACKGROUND AND OBJECTIVE: In recent years, there has been an increased interest in depression and diabetes risk factors. Our objectives were 1) Study the variables associated with the presence of depression in patients with type 1 diabetes mellitus (DM1), 2) to analyze potential risk factors for depression in these patients, and 3) to study a possible explanatory model of depression scores in these patients. PATIENTS AND METHODS: 207 patients with DM1. We evaluated sociodemographic and biomedical variables by means of a structured interview. We assessed psychological variables by means of the Scale for Depression in Type 1 Diabetes (EDDI-1) and the Spanish version of Diabetes Quality of Life (Es DQOL). RESULTS: Prevalence of depression was 21,7%. Variables associated with risk of depression in this sample were to be female; be unemployed; smoking; having complications of diabetes or other physical conditions; not perceiving family support or support from friends or colleagues in relation to diabetes; having a high number of weekly hyperglycemia; and a poor quality of life. A model based on previous research was obtained. This model explains a high percentage of the variability in the scores of patients in the EDDI-1. CONCLUSIONS: These results provide an empirical support to the knowledge of the risk factors associated with depression in patients with DM1. Glycemic control and quality of life have an important effect on the scores of depression in these patients, providing information for their treatment.

OBJECTIVE: To assess the impact of a telemedicine visit using the platform Diabetic compared with a face-to-face visit on clinical outcomes, patients' health-related quality of life (HRQoL), and physicians' satisfaction in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS: PLATEDIAN (Telemedicine on Metabolic Control in Type 1 Diabetes Mellitus Andalusian Patients) (NCT03332472) was a multicenter, randomized, 6-month follow-up, open-label, parallel-group controlled study performed in patients with type 1 diabetes with suboptimal metabolic control (HbA1c <8% [<64 mmol/mol]), treated with multiple daily injections. A total of 388 patients were assessed for eligibility; 379 of them were randomized 1:1 to three face-to-face visits (control cohort [CC]) (n = 167) or the replacement of an intermediate face-to-face visit by a telemedicine visit using Diabetic (intervention cohort [IC]) (n = 163). The primary efficacy end point was the mean change of HbA1c levels from baseline to month 6. Other efficacy and safety end points were mean blood glucose, glucose variability, episodes of hypoglycemia and hyperglycemia, patient-reported outcomes, and physicians' satisfaction. RESULTS: At month 6, the mean change in HbA1c levels was -0.04 ± 0.5% (-0.5 ± 5.8 mmol/mol) in the CC and 0.01 ± 0.6% (0.1 ± 6.0 mmol/mol) in the IC (P = 0.4941). The number of patients who achieved HbA1c <7% (<53 mmol/mol) was 73 and 78 in the CC and IC, respectively. Significant differences were not found regarding safety end points at 6 months. Changes in HRQoL between the first visit and final visit did not differ between cohorts, and, regarding fear of hypoglycemia (FH-15 score ≥28), statistically significant differences observed at baseline remained unchanged at 6 months (P < 0.05). CONCLUSIONS: The use of telemedicine in patients with type 1 diabetes with HbA1c <8% (<64 mmol/mol) provides similar efficacy and safety outcomes as face-to-face visits.

BACKGROUND: Vitamin D has an immunoregulatory action in Inflammatory Bowel Disease (IBD) as well as other immune-mediated disorders. Its influence on intestinal permeability, innate and adaptive immunity, and the composition and diversity of the microbiota contribute to the maintenance of intestinal homeostasis. Patients with IBD have a greater prevalence of vitamin D deficiency than the general population, and a possible association between this deficit and a worse course of the disease. However, intervention studies in patients with IBD have proved inconclusive. OBJECTIVE: To review all the evidence concerning the role of vitamin D as an important factor in the pathophysiology of IBD, review the associations found between its deficiency and the prognosis of the disease, and draw conclusions for the practical application from the main intervention studies undertaken. METHODS: Structured search and review of basic, epidemiological, clinical and intervention studies evaluating the influence of vitamin D in IBD, following the basic principles of scientific data. RESULTS: Vitamin D deficiency is associated with disease activity, quality of life, the consumption of social and healthcare resources, and the durability of anti-TNFα biological treatment. Determination of new metabolites of vitamin D, measurement of its absorption capacity and questionnaires about sun exposure could help identify groups of IBD patients with a special risk of vitamin D deficiency. CONCLUSION: Well-designed intervention studies are needed in IBD, with probably higher objective plasma doses of vitamin D to establish its efficacy as a therapeutic agent with immunomodulatory properties. Meanwhile, vitamin D deficiency should be screened for and corrected in affected patients in order to achieve adequate bone and phosphocalcic metabolism.

The concept of prebiotics, probiotics, and symbiotics and their use in different situations of daily clinical practice related to clinical nutrition is reviewed, as well as their role in the treatment/prevention of diarrhea (acute, induced by antibiotics, secondary to radiotherapy), inflammatory bowel disease (ulcerative colitis and pouchitis), in colonic health (constipation, irritable bowel), in liver disease (steatosis and minimum encephalopathy), and in intensive care, surgical, and liver transplantation. While their effectiveness for preventing antibiotic-induced diarrhea and pouchitis in ulcerative colitis appears to be shown, additional studies are needed to establish recommendations in most clinical settings. The risk of infection associated to use of probiotics is relatively low; however, there are selected groups of patients in whom they should be used with caution (as jejunum infusion).

BACKGROUND AND OBJECTIVE: Advantages of continuous subcutaneous insulin infusion (CSII) over multiple daily injections with glargine (MDI/G) are still uncertain. We compared CSII vs. MDI/G therapy in unselected patients with type 1 diabetes using continuous glucose monitoring (CGSM). The primary end-points were glycaemic control and quality of life (QOL). METHODS: A total of 45 patients with long-term diabetes and mean HbA1c values of 8.6±1.8% (70.5±15.4mmol/mol), previously treated with MDI/NPH, were switched to MDI/G for 6 months and then, unfulfilling therapy CSII indication, were randomly assigned to CSII or MDI/G for another six months. We evaluated QOL (EsDqol) and glycaemic control by measuring HbA1c levels, rate of hypoglycaemia, ketoacidosis and CGSM data. RESULTS: After the first phase (MDI/NPH to MDI/G) there was a significant improvement in total EsDQOL (99.72±18.38 vs. 92.07±17.65; p<0.028), a 0.5% decrease in HbA1c values (8.4±1.2 vs. 7.9±0.7% [68±9.7 vs. 63±5.5mmol/mol]; p<0.032), an improvement in glycaemic variability (standard deviation 66.9±14 vs. 59.4±16mg/dl; p<0.05), a decrease in insulin requirements (0.87±0.29 vs. 0.80±0.25U/kg; p<0.049), a decrease in number of severe hypoglycaemia episodes (0.44±0.9 vs. 0.05±0.2; p<0.014), and an increase in periods of normoglycaemia measured with CGSM (15.8±10.9% vs. 23±18.4%; p<0.003). Six months after randomization, significant improvements were seen in the HbA1c (7.9±0.7 vs. 7±0.6% [63±5.5 vs. 53±4.5mmol/mol]; p<0.001) and EsQOL (91.66±22 vs. 84.53±1.63; p<0.045) only in the CSII group. The HbA1c value was significantly lower when compared with the MDI/G group (CSII 7±0.6% [53±4.5mmol/mol] vs. MDI/G 7.6±0.9% [59.6±7.7mmol/mol]; p<0.03). CONCLUSIONS: Intensive insulin therapy with CSII vs. MDI/G was associated with better levels of HbA1c in patients with long-term type 1 diabetes.

Somatostatin analogs (SSA) are the mainstay of pharmacological treatment for pituitary adenomas. However, some patients escape from therapy with octreotide, a somatostatin receptor 2 (sst2)-preferring SSA, and pasireotide, a novel multi-sst-preferring SSA, may help to overcome this problem. It has been proposed that correspondence between sst1-sst5 expression pattern and SSA-binding profile could predict patient's response. To explore the cellular/molecular features associated with octreotide/pasireotide response, we performed a parallel comparison of their in vitro effects, evaluating sst1-sst5 expression, intracellular Ca2+ signaling ([Ca2+]i), hormone secretion and cell viability, in a series of 85 pituitary samples. Somatotropinomas expressed sst5>sst2, yet octreotide reduced [Ca2+]i more efficiently than pasireotide, while both SSA similarly decreased growth hormone release/expression and viability. Corticotropinomas predominantly expressed sst5, but displayed limited response to pasireotide, while octreotide reduced functional endpoints. Non-functioning adenomas preferentially expressed sst3 but, surprisingly, both SSA increased cell viability. Prolactinomas mainly expressed sst1 but were virtually unresponsive to SSA. Finally, both SSA decreased [Ca2+]i in normal pituitaries. In conclusion, both SSA act in vitro on pituitary adenomas exerting both similar and distinct effects; however, no evident correspondence was found with the sst1-sst5 profile. Thus, it seems plausible that additional factors, besides the simple abundance of a given sst, critically influence the SSA response.

We present a case of severe acute pancreatitis induced by hypertriglyceridemia secondary to lipoprotein lipase (LPL) deficiency in a pregnant patient with gestational diabetes, initially maneged with diet but it was later necessary to carry out artificial nutricional support measures: total parenteral nutrition. LPL deficiency might cause severe hypertriglyceridemia, repetition acute pancreatitis which is an unwieldy and severe situation during pregnancy. Acute familial hypertriglyceridemia pancreatitis accounts for 5% of cases, including LPL deficiency. The goal of treatment is to reach triglycerides levels below 500 mg/dl, being very low fat diet the treatment of choice, drugs or plasmapheresis techniques can also be associated. TPN enriched in ω3 fatty acids and glutamine was safe and effective in our patient with significant decrease in triglyceride levels.
Presentamos un caso de pancreatitis aguda severa inducida por hipertrigliceridemia secundaria a déficit de lipoproteín lipasa (LPL) en una paciente gestante con diabetes gestacional, manejada inicialmente con dieta, siendo necesario posteriormente llevar a cabo medidas de soporte nutricional artificial: nutrición parenteral total. El déficit de LPL causa hipertrigliceridemia severa y, frecuentemente, pancreatitis aguda de repetición, situación de difícil manejo y de importante gravedad durante la gestación. La pancreatitis aguda por hipertrigliceridemia familiar supone el 5% de los casos, incluyéndose el déficit de LPL. El objetivo del tratamiento será alcanzar niveles de triglicéridos inferiores a 500 mg/dl, siendo la dieta muy baja en grasa el tratamiento de elección, pudiéndose asociar también fármacos o técnicas de plasmaféresis. La nutrición parenteral total enriquecida en ácidos grasos ï·3 y glutamina resultó segura y eficaz en la paciente, con un descenso importante de los niveles de triglicéridos.

BACKGROUND AND OBJECTIVE: Vitamin D deficiency and metabolic syndrome are 2 very common health problems in the Spanish population. It has been suggested that patients with metabolic syndrome may be vitamin D deficient more often than subjects without it and that low vitamin D levels may predispose to metabolic syndrome development. However, the results of prospective and intervention studies have been different and such relationship remains unclear. We assessed the relationship between 25-hydroxyvitamin D levels and the prevalence and incidence of metabolic syndrome. PATIENTS AND METHODS: We undertook a population-based cohort study in Spain. At baseline (1996-1998), 1,226 subjects were evaluated. Follow-up visits were performed in 2002-2004 and 2005-2007.At baseline and follow-up, participants underwent an interview and a standardized clinical examination with an oral glucose tolerance test in those subjects without known diabetes. At the second visit, 25-hydroxyvitamin D levels and intact parathyroid hormone levels were measured. RESULTS: The prevalence of metabolic syndrome at the second and third visit was 29.4 and 42.5%, respectively. Mean levels of 25-hydroxyvitamin D were lower in subjects with metabolic syndrome: 21.7 (6.21) vs 23.35 (6.29) ng/ml, P<.001.The prevalence of vitamin D deficiency (25-hydroxyvitamin D<20 ng/ml) at the second evaluation was 34.7%, with significant differences between subjects with and without metabolic syndrome(34.6 vs 26.5%, P<.01). Men with vitamin D deficiency had more frequently hypertension and metabolic syndrome than men with normal levels. Women with vitamin D deficiency had more frequently hyperglycemia, hypertension, increased waist circumference and hypertriglyceridemia. In a prospective study, 25-hydroxyvitamin D values<20 ng/ml were not significantly associated with an increased risk of developing metabolic syndrome in the next 5 years (odds ratio 0,99, 95% confidence interval 0.57-1.7, P=.97) after adjusting by sex and age. CONCLUSIONS: Vitamin D deficiency is associated with an increased prevalence but not with an increased incidence of metabolic syndrome.

BACKGROUND & AIMS: To investigate the relationship between levels of 25-hydroxyvitamin D and the incidence of type 2 diabetes in a Spanish population. METHODS: We undertook a population-based prospective study in a population from southern Spain. The first phase of the study (1996-1998) included 1226 individuals. Of this original cohort, 988 persons were reassessed in 2002-2004 and 961 in 2005-2007. Measurements were made of 25-hydroxyvitamin D and intact parathyroid hormone in 2002-2004 and an oral glucose tolerance test was done in three time points. RESULTS: The incidence of diabetes in subjects with 25-hydroxyvitamin D levels ≤ 18.5 ng/mL (percentile 25) was 12.4% vs 4.7% in subjects with levels >18.5 ng/mL. The likelihood of having diabetes during the four years of follow-up was significantly lower in the subjects with higher levels of 25-hydroxyvitamin D [OR = 0.17 (0.05-0.61)]. None of the subjects with levels higher than 30 ng/mL developed diabetes. CONCLUSION: In this prospective study, we found a significant inverse association between serum 25-hydroxyvitamin D levels and the risk for type 2 diabetes in a population from the south of Spain.

We evaluated a telemedicine system in patients with type 1 diabetes who had optimized treatment with an insulin pump and a real-time continuous glucose monitoring system. We conducted a prospective, one-year study of 15 subjects. Three medical visits took place: pre-baseline, baseline and at 6 months. Each month the subjects transmitted information from the glucose meter, glucose sensor and insulin pump. We adjusted the treatment and returned the information by email. We evaluated psychological and metabolic variables, including HbA(1c), hypoglycaemia, hyperglycaemia and glucose variability. At baseline the mean age of the subjects was 40 years and the mean duration of diabetes was 22 years. There was a significant reduction in HbA(1c) (7.50 to 6.97%) at 6 months, a significant increase in the number of self-monitoring blood glucose checks per day (5.2 to 6.2), and significant improvements in variability: MODD, mean of daily difference (67 to 53) and MAGE, mean amplitude of glycaemic excursions (136 to 102). There were significant improvements in quality of life (92 to 87), satisfaction with the treatment (34 to 32) and less fear of hypoglycaemia (36 to 32). Adult subjects with type 1 diabetes on treatment with a continuous insulin infusion system and a real time glucose sensor and who have acceptable metabolic control and optimized treatment can benefit from the addition of a telemetry system to their usual outpatient follow-up.

BACKGROUND: Continuous subcutaneous insulin infusion (CSII) may be an alternative to multiple daily injections (MDI) in pre-gestational diabetes during pregnancy. However, no clear improvement in obstetric and perinatal outcome has so far been established for CSII treatment. METHODS: In a case-control study, 35 pregnancies treated with CSII and 64 pregnancies treated with MDI treatment were evaluated. Metabolic control and obstetric and perinatal outcome were compared. RESULTS: Women in the CSII group improved their metabolic control (hemoglobin A1c before CSII, 7.83 +/- 0.97%; 3-6 months after, 6.77 +/- 0.61%; P < 0.05). Hemoglobin A1c before pregnancy was lower in the CSII group (6.62 +/- 0.60%) than in the MDI group (7.59 +/- 1.61%) (P < 0.05). No other significant differences, either in metabolic control of diabetes or in obstetric and perinatal outcome, were found. CONCLUSIONS: CSII treatment is safe in pregnancy, but it has not yet been associated with any improved pregnancy outcome.
