Objective: Polydipsia and polyuria are common reasons for referral to the Pediatric Endocrine clinic. In the absence of hyperglycemia, diabetes insipidus (DI) should be considered. The objectives of the study were to determine the prevalence of central DI (CDI) in a group of children presenting for evaluation of polydipsia and polyuria, and to determine if predictive features were present in patients in whom the diagnosis of DI was made.Methods: The study was a retrospective chart review of children presenting to the endocrine clinic with complaints of polydipsia and polyuria over a 5-year period.Results: The charts of 41 patients (mean age 4.9 ± 3.7 years, 28 males) were reviewed. CDI was diagnosed in 8 (20%) children based on abnormal water deprivation test (WDT) results. All but one patient had abnormal magnetic resonance imaging (MRI) findings, the most common being pituitary stalk thickening. Children with DI were older (7.86 ± 4.40 vs. 4.18 ± 3.20 years, P = .01) and had a higher propensity for cold beverages intake and unusual water-seeking behaviors compared to those without DI. Baseline WDT also revealed higher serum sodium (Na) and osmolality.Conclusion: The incidence of CDI in children presenting with polydipsia and polyuria is low. Factors associated with higher likelihood of pathology include older age, propensity for cold beverage intake, and higher baseline serum Na and osmolality on a WDT.Abbreviations:BMI = body mass indexCDI = central diabetes insipidusDI = diabetes insipidusNa = sodiumWDT = water deprivation test 相似文献

Objective: Traumatic brain injury (TBI) is now recognized as a major public health concern in the United States and is associated with substantial morbidity and mortality in both children and adults. Several lines of evidence indicate that TBI-induced hypopituitarism is not infrequent in TBI survivors and may contribute to the burden of illness in this population. The goal of this article is to review the published data and propose an approach for the neuroendocrine evaluation and management of these patients.Methods: To identify pertinent articles, electronic literature searches were conducted using the following keywords: “traumatic brain injury,” “pituitary,” “hypopituitarism,” “growth hormone deficiency,” “hypogonadism,” “hypoadrenalism,” and “hypothyroidism.” Relevant articles were identified and considered for inclusion in the present article.Results: TBI-induced hypopituitarism appears to be more common in patients with severe TBI. However, patients with mild TBI or those with repeated, sports-, or blast-related TBI are also at risk for hypopituitarism. Deficiencies of growth hormone and gonadotropins appear to be most common and have been associated with increased morbidity in this population. A systematic approach is advised in order to establish the presence of pituitary hormone deficiencies and implement appropriate replacement therapies.Conclusion: The presence of traumatic hypopituitarism should be considered during the acute phase as well as during the rehabilitation phase of patients with TBI. All patients with moderate to severe TBI require evaluation of pituitary function. In addition, symptomatic patients with mild TBI and impaired quality of life are at risk for hypopituitarism and should be offered neuroendocrine testing.Abbreviations: CBG = corticosteroid-binding globulin DI = diabetes insipidus GH = growth hormone IGF-1 = insulin-like growth factor 1 SIADH = syndrome of inappropriate antidiuretic hormone T4 = thyroxine TBI = traumatic brain injury TSH = thyroid-stimulating hormone 相似文献

Objective: To summarize the characteristics of patients with pituitary stalk thickening, analyze the association between pituitary stalk width and hypopituitarism, and develop a diagnostic model to differentiate neoplastic and inflammatory origins.Methods: A total of 325 patients with pituitary stalk thickening in a tertiary teaching hospital between January 2012 and February 2018 were enrolled. Basic characteristics and hormonal status were evaluated. Indicators to predict etiology in patients with histologic diagnoses were analyzed.Results: Of the 325 patients, 62.5% were female. Deficiency in gonadotropin was most common, followed by corticotropin, growth hormone, and thyrotropin. The increase in pituitary stalk width was associated with a risk of central diabetes insipidus (odds ratio [OR], 3.57; P<.001) and with a combination of central diabetes insipidus and anterior pituitary deficiency (OR, 2.28; P = .029). The cut-off pituitary stalk width of 4.75 mm had a sensitivity of 69.2% and a specificity of 71.4% for the presence of central diabetes insipidus together with anterior pituitary deficiency. Six indicators (central diabetes insipidus, pattern of pituitary stalk thickening, pituitary stalk width, neutrophilic granulocyte percentage, serum sodium level, and gender) were used to develop a model having an accuracy of 95.7% to differentiate neoplastic from inflammatory causes.Conclusion: Pituitary stalk width could indicate the presence of anterior pituitary dysfunction, especially in central diabetes insipidus patients. With the use of a diagnostic model, the neoplastic and inflammatory causes of pituitary stalk thickening could be preliminarily differentiated.Abbreviations: APD = anterior pituitary dysfunction; AUC = area under the curve; CDI = central diabetes insipidus; GH = growth hormone; MRI = magnetic resonance imaging; OR = odd ratio; PHBS = posterior hypophyseal bright spots; PST = pituitary stalk thickening; PSW = pituitary stalk width 相似文献

Objective:To evaluate the endocrine abnormalities in intracranial germ cell tumors (iGCTs) treated with radio-therapy (RT), and to discuss the effects of RT on pituitary functions.Methods: Seventy-seven patients diagnosed with iGCTs who had received RT and endocrine follow-up in Huashan Hospital between January 2010 and July 2017 were retrospectively analyzed, consisting of 49 germinomas and 28 NGGCTs. The median follow-up period was 50.0 months. Fifty-one patients had radiologically proved suprasellar/sellar lesions.Results: The male to female ratio was 62/15. The median endocrine follow-up period was 19 (4, 42) months. The median age at the last endocrine visit was 18 (16, 20) years old. The 5-year overall and recurrence-free survival were both 98.7%. The overall prevalence of central adrenal insufficiency (CAI), central hypothyroidism (CHT), central hypogonadism (CHG), hyperprolactinemia, and central diabetes insipidus (CDI) was 57.3%, 56%, 56.6%, 35.3%, and 52.1%, respectively, after RT. Patients having suprasellar/sellar lesions showed significantly higher post-therapeutic prevalence of hypopituitarism than those who didn’t. Compared to that before RT, CAI, CHT, and CHG weren’t significantly improved while the levels of prolactin and the prevalence of CDI declined significantly (P =.03 and.001). The radiation doses to pituitary and hypothalamus between those with and without CAI, CHT, and CHG weren’t significantly different.Conclusion: The prevalence of hypopituitarism was high in iGCTs, especially in those with suprasellar/sellar involvement. The levels of prolactin and the prevalence of CDI declined significantly after RT. The hypopituitarism in iGCTs was mainly induced by tumor effects, and RT showed no additional damage to pituitary functions in our study.Abbreviations: AFP = alpha-fetoprotein; CAI = central adrenal insufficiency; CDI = central diabetes insipidus; CHG = central hypogonadism; CHT = central hypothyroidism; CT = computed tomography; DA = dopamine; GH = growth hormone; βHCG = beta-human chorionic gonadotropin; HPA = hypothalamus-pituitary-adrenal; HPG = hypothalamus-pituitary-gonadal; HPL = hyperprolactinemia; HPT = hypothalamus-pituitary-thyroid; iGCT = intracranial germ cell tumor; IGF-1 = insulin-like growth factor 1; NGGCT = nongerminomatous germ cell tumors; OS = overall survival; PFS = progression-free survival; PRL = hypothalamus-pituitary-prolactin; RT = radiotherapy 相似文献

Objective: Transsphenoidal surgery (TS) for sellar lesions is an established and safe procedure, but complications can occur, particularly involving the neuroendocrine system. We hypothesized that postoperative care of TS patients would be optimized when performed by a coordinated team including a pituitary neurosurgeon, endocrinologists, and a specialty nurse.Methods: We implemented a formalized, multidisciplinary team approach and standardized postoperative protocols for the care of adult patients undergoing TS by a single surgeon (J.N.B.) at our institution beginning in July 2009. We retrospectively compared the outcomes of 214 consecutive TS-treated cases: 113 cases prior to and 101 following the initiation of the team approach and protocol implementation. Outcomes assessed included the incidence of neurosurgical and endocrine complications, length of stay (LOS), and rates of hospital readmission and unscheduled clinical visits.Results: The median LOS decreased from 3 days preteam to 2 days postteam (P<.01). Discharge occurred on postoperative day 2 in 46% of the preteam group patients compared to 69% of the postteam group (P<.01). Rates of early postoperative diabetes insipidus (DI) and readmissions within 30 days for syndrome of inappropriate antidiuretic hormone (SIADH) or other complications did not differ between groups.Conclusion: Implementation of a multidisciplinary team approach was associated with a reduction of LOS. Despite earlier discharge, postoperative outcomes were not compromised. The endocrinologist is central to the success of this team approach, which could be successfully applied to care of patients undergoing TS, as well as other types of endocrine surgery at other centers.Abbreviations:CSF = cerebrospinal fluidDDAVP = desmopressinDI = diabetes insipidusLOS = length of stayPOD = postoperative daySIADH = syndrome of inappropriate antidiuretic hormoneTS = transsphenoidal surgery 相似文献

Objective: The water deprivation test (WDT) is widely used for the differential diagnosis of the polyuria-polydipsia syndrome (PPS). However, it is inconvenient and may not always be precise in differentiating partial forms of diabetes insipidus (DI) from primary polydipsia (PP). The aim of this study was to evaluate the results of a combined outpatient and inpatient overnight WDT protocol that included an overnight unsupervised period concerning its feasibility and safety.Methods: We performed a retrospective analysis of clinical data and laboratory results of 52 patients with PPS undergoing WDT at a single center.Results: PP was the most frequent diagnosis, followed by complete central DI (cCDI), partial central DI (pCDI), and nephrogenic DI (NDI). Over 90% of the patients showed an expected increase in serum osmolality at the end of the dehydration period. There were no reports of complications during the overnight deprivation period. Post-dehydration urine osmolality and urine-to-serum osmolality ratio significantly differentiated all the groups (P<.05), except for cCDI and NDI, which could be differentiated by basal and post-dehydration vasopressin (AVP) levels (P<.05 for both). Although these measurements were useful for differentiating patients according to their allocation groups, results from WDT and direct AVP levels may often require a comprehensive diagnostic approach, particularly in the challenging groups of PP and pCDI.Conclusion: A combined outpatient and inpatient overnight WDT protocol is safe and feasible when the test is performed with special care at experienced centers. Newer diagnostic tools are expected to improve the accuracy of PPS diagnosis.Abbreviations: AQP2 = aquaporin-2; AVP = vasopressin; CDI = central diabetes insipidus; cCDI = complete central diabetes insipidus; DDAVP = desmopressin; DI = diabetes insipidus; IQR = interquartile range; MRI = magnetic resonance imaging; Na+ = sodium; NDI = nephrogenic diabetes insipidus; pCDI = partial central diabetes insipidus; PP = primary polydipsia; PPS = polyuria-polydipsia syndrome; S_osm = serum osmolality; U_osm = urine osmolality; WDT = water deprivation test 相似文献

Objective: To review data implicating microbiota influences on Coronavirus Disease 2019 (COVID-19) in patients with diabetes.Methods: Primary literature review included topics: “COVID-19,” “SARS,” “MERS,” “gut micro-biota,” “probiotics,” “immune system,” “ACE2,” and “metformin.”Results: Diabetes was prevalent (~11%) among COVID-19 patients and associated with increased mortality (about 3-fold) compared to patients without diabetes. COVID-19 could be associated with worsening diabetes control and new diabetes diagnosis that could be linked to high expression of angiotensin-converting enzyme 2 (ACE2) receptors (coronavirus point of entry into the host) in the endocrine pancreas. A pre-existing gut microbiota imbalance (dysbiosis) could contribute to COVID-19–related complications in patients with diabetes. The COVID-19 virus was found in fecal samples (~55%), persisted for about 5 weeks, and could be associated with diarrhea, suggesting a role for gut dysbiosis. ACE2 expressed on enterocytes and colonocytes could serve as an alternative route for acquiring COVID-19. Experimental models proposed some probiotics, including Lactobacillus casei, L. plantarum, and L. salivarius, as vectors for delivering or enhancing efficacy of anti-coronavirus vaccines. These Lactobacillus probiotics were also beneficial for diabetes. The potential mechanisms for interconnections between coronavirus, diabetes, and gut microbiota could be related to the immune system, ACE2 pathway, and metformin treatment. There were suggestions but no proof supporting probiotics benefits for COVID-19 infection.Conclusion: The data suggested that the host environment including the gut microbiota could play a role for COVID-19 in patients with diabetes. It is a challenge to the scientific community to investigate the beneficial potential of the gut microbiota for strengthening host defense against coronavirus in patients with diabetes. 相似文献

Objective: Latin American Thyroid Society (LATS) Hypothyroidism Clinical Practice Guidelines recommend case finding of hypothyroid patients in multiple and different situations that agree with other Society guidelines. However, the detection of hypothyroidism in type 2 diabetes mellitus (T2DM) or metabolic syndrome (MetS) patients is not mentioned in particular. In the recent years, several basic and epidemiologic studies have appeared showing that a lower thyroid function and MetS/T2DM are associated. Hence, the aim of this review is to manifest the LATS position on the diagnosis of hypothyroidism in both MetS and T2DM patients.Methods: A search was made in PubMed using the following terms: “hypothyroidism” AND “diabetes” OR “metabolic syndrome.” The most relevant studies describing the prevalence and complications due to hypothyroidism in both MetS and T2DM patients were selected.Results: The current document reviews new information from studies that have shown that the prevalence of hypothyroidism is higher in T2DM patients (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.5 to 4.7) and that diabetic complications are more prevalent in subclinical hypothyroidism (ScH). The incidence of T2DM is 1.09-fold higher with each doubling of thyroid-stimulating hormone (TSH) mIU/L (95% CI, 1.06 to 1.12), and the incidence of prediabetes increases 15% (hazard ratio, 1.15; 95% CI, 1.04 to 1.26) in patients with TSH >5 mIU/L. Similarly, MetS is more prevalent in ScH compared to euthyroid individuals (OR, 1.31; 95% CI, 1.08 to 1.60).Conclusion: Thyroid function is affected in MetS and T2DM, and hypothyroidism is more common in these patients. Diabetic complications are more frequent in ScH patients. Therefore, LATS now recommends aggressive case finding of hypothyroidism in both MetS and T2DM patients.Abbreviations: CI = confidence interval; GLUT4 = glucose transporter 4; HOMA-IR = homeostatic model assessment for insulin resistance; HR = hazard ratio; LATS = Latin American Thyroid Society; MetS = metabolic syndrome; OR = odds ratio; ScH = subclinical hypothyroidism; T2DM = type 2 diabetes mellitus; T3 = triiodothyronine; T4 = thyroxine; TSH = thyroid-stimulating hormone 相似文献

Objective: In December 2019, a novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused an outbreak of coronavirus disease 2019 (COVID-19) that resulted in a global pandemic with substantial morbidity and mortality. Currently, there is no specific treatment or approved vaccine against COVID-19. The underlying associated comorbidity and diminished immune function of some pituitary patients (whether caused by the disease and its sequelae or treatment with excess glucocorticoids) increases their risk of contracting and developing complications from COVID-19 infection.Methods: A review of studies in PubMed and Google Scholar published between January 2020 to the time of writing (May 1, 2020) was conducted using the search terms ‘pituitary,’ ‘coronavirus,’ ‘COVID-19’, ‘2019-nCoV’, ‘diabetes mellitus’, ‘obesity’, ‘adrenal,’ and ‘endocrine.’Results: Older age and pre-existing obesity, hypertension, cardiovascular disease, and diabetes mellitus increase the risk of hospitalization and death in COVID-19 patients. Men tend to be more severely affected than women; fortunately, most men, particularly of younger age, survive the infection. In addition to general comorbidities that may apply to many pituitary patients, they are also susceptible due to the following pituitary disorder–specific features: hypercortisolemia and adrenal suppression with Cushing disease, adrenal insufficiency and diabetes insipidus with hypopituitarism, and sleep-apnea syndrome and chest wall deformity with acromegaly.Conclusion: This review aims to focus on the impact of COVID-19 in patients with pituitary disorders. As most countries are implementing mobility restrictions, we also discuss how this pandemic has affected patient attitudes and impacted our decision-making on management recommendations for these patients.Abbreviations: ACE = angiotensin-converting enzyme; AI = adrenal insufficiency; ARB = angiotensin receptor blocker; ARDS = acute respiratory disease syndrome; COVID-19 = coronavirus disease 2019; CPAP = continuous positive airway pressure; DI = diabetes insipidus; DM = diabetes mellitus; SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2 相似文献

Objective: Hyperglycemia is a common problem in hospitalized patients receiving artificial nutrition, and this development of hyperglycemia during parenteral nutrition therapy (PNT) and enteral nutrition therapy (ENT) increases the risks of hospital-related complications and mortality. This review aims to discuss the pathogenesis of hyperglycemia from artificial nutrition in the hospital, summarize current evidence on the treatment of hyperglycemia with insulin in these patients, and review current guidelines.Methods: A systematic literature review using PubMed and the Medical Subject Headings (MeSH) terms “hyperglycemia,” “enteral nutrition,” and “parenteral nutrition” were used to evaluate the current evidence available for treating noncritically ill patients with hyperglycemia who were receiving artificial nutrition.Results: The literature review showed that few randomized control trials exist regarding treatment of hyperglycemia in this cohort of patients, and the multiple retrospective evaluations that have addressed this topic provided varied results. In general, intravenous (IV) continuous insulin infusion offers the best glycemic control; however, this route of insulin administration is often burdensome for floor patients and their care teams. Administration of scheduled subcutaneous (SQ) insulin in patients on ENT or PNT is a safe and effective way to manage hyperglycemia, however limited data exist on an appropriate insulin regimen.Conclusion: Further prospective, randomized control trials are necessary to determine the optimal treatment of hyperglycemia for patients receiving ENT or PNT.Abbreviations: BG = blood glucose; CG = conventional glycemic control; ENT = enteral nutrition therapy; GIP = glucose-dependent insulinotropic polypeptide; GLP-1 = glucagon-like peptide 1; IG = intensive glycemic control; IV = intravenous; NPH = neutral protamine Hagedorn; PNT = parenteral nutrition therapy; SQ = subcutaneous; T2DM = type 2 diabetes mellitus; TDD = total daily dose; TPN = total parenteral nutrition 相似文献

Objective: Type 1 diabetes (T1D) is characterized by autoimmune β-cell destruction, but exocrine pancreas abnormalities may also play a role in the disease pathophysiology. Herein, we review the current evidence of exocrine damage in T1D and discuss its underlying pathophysiology, clinical evaluation, and treatment.Method: Extensive literature search was performed for “type 1 diabetes” and “exocrine dysfunction” on PubMed and Google Scholar databases.Results: T1D pancreata are significantly smaller than controls, both in weight and volume. T cells, dendritic cells, neutrophils, and products of complement activation are seen in T1D exocrine tissues. Exocrine pancreas fibrosis, arteriosclerosis, fatty infiltration, and acinar atrophy are also observed on histology. Pancreatic exocrine insufficiency (PEI) can be assessed through direct exocrine testing, fecal elastase concentration, and measurement of serum exocrine enzymes. The prevalence of PEI in T1D varies by modality and study but is consistently greater than controls. The clinical relevance of PEI in T1D is debatable, as many patients with laboratory evidence of PEI are asymptomatic. However, in PEI-symptomatic patients reported benefits of pancreatic enzyme replacement therapy (PERT) include relief of gastrointestinal symptoms, improved quality of life, better glycemic control, and optimal nutrition.Conclusion: Exocrine pancreas abnormalities often occur in T1D. Whether exocrine dysfunction occurs simultaneously with β-cell destruction, as a result of β-cell loss, or as a combination of both remains to be definitively answered. In T1D with gastrointestinal complaints, PEI should be evaluated, usually via fecal elastase measurements. PERT is recommended for T1D patients with symptoms and laboratory evidence of PEI.Abbreviations: AAb+ = autoantibody positive; AAb- = autoantibody negative; FEC = fecal elastase concentration; PEI = pancreatic exocrine insufficiency; PERT = pancreatic enzyme replacement therapy; PP = pancreatic polypep-tide; T1D = type 1 diabetes 相似文献

Objective: Graft-versus-host disease (GVHD) is an immune phenomenon that occurs in 30 to 70% of patients after allogeneic hematopoietic stem cell transplantation (HST). Chronic GVHD is a state of immune dysregulation wherein, depending on the severity and organ involved, patients may require prolonged treatment with additional or higher corticosteroids and other immunosuppressive agents. The objective of this study was to review the endocrine manifestations following HST that can arise as a consequence of the primary disease or its treatment, including chemotherapeutic agents, corticosteroids, radiation, or GVHD.Methods: We performed a narrative review of GVHD after HST. An English-language search for relevant studies was conducted on PubMed from inception to August 1, 2018, using the following search terms: “endocrine complications,” “bone marrow transplantation,” “graft-versus-host disease,” and “GVHD.” The reference lists of relevant studies were also reviewed.Results: Chronic GVHD may be associated with considerable pediatric growth impairment and may also contribute to thyroid gland dysfunction and thyroid cancer. These patients may also be at increased risk for low bone mineral density, reduced fertility, metabolic syndrome, and suppression of the pituitary-adrenal axis with adrenal insufficiency.Conclusion: This review indicates the importance of monitoring, diagnosing, and properly treating the endocrine complications in this population. More studies are needed to investigate the independent impact of GVHD on the endocrine system and treatment for complications.Abbreviations: BMD = bone mineral density; GH = growth hormone; GVHD = graft-versus-host disease; HST = hematopoietic stem cell transplantation; IGF-1 = insulin-like growth factor 1 相似文献

Objective: Studies of hyperglycemic emergencies with hyperosmolality, including hyperglycemic hyperosmolar state (HHS) and “mixed presentation” with features of diabetic ketoacidosis (DKA) and HHS, are lacking in children. Objectives were to determine the incidence of DKA, HHS, and mixed presentation in a pediatric population, to characterize complications, and to assess accuracy of associated diagnosis codes.Methods: Retrospective cohort study of 411 hyperglycemic emergencies in pediatric patients hospitalized between 2009 and 2014. Hyperglycemic emergency type was determined by biochemical criteria and compared to the associated diagnosis code.Results: Hyperglycemic emergencies included: 333 DKA, 54 mixed presentation, and 3 HHS. Altered mental status occurred more frequently in hyperosmolar events (P<.0001), and patients with hyperosmolarity had 3.7-fold greater odds of developing complications compared to those with DKA (P =.0187). Of those with DKA, 98.5% were coded correctly. The majority (81.5%) of mixed DKA-HHS events were coded incorrectly. Events coded incorrectly had 3.1-fold greater odds of a complication (P =.02).Conclusion: A mixed DKA-HHS presentation occurred in 13.8% of characterized hyperglycemic emergencies, whereas HHS remained a rare diagnosis (0.8%) in pediatrics. Hyperosmolar events had higher rates of complications. As treatment of hyperosmolarity differs from DKA, its recognition is essential for appropriate management.Abbreviations: AMS = altered mental status; DKA = diabetic ketoacidosis; EMR = electronic medical record; HHS = hyperglycemic hyperosmolar state; ICD-9 = International Classification of Diseases, Ninth Revision; ISPAD = International Society of Pediatric and Adolescent Diabetes; NODM = new-onset diabetes mellitus; T1DM = type 1 diabetes mellitus; T2DM = type 2 diabetes mellitus 相似文献

Objective: To evaluate the impact of different subcutaneous basal insulin regimens on glycemic variability (GV) and hospital complications in non-intensive care unit (ICU) patients with type 2 diabetes (T2D).Methods: This study is a post hoc analysis of 279 general medicine and surgery patients treated with either a “Basal Bolus” insulin regimen using glargine once daily and glulisine before meals or a “Basal Plus” regimen using glargine once daily plus correction doses of glulisine before meals for glucose >140 mg/dL. GV was calculated as mean delta (Δ) daily glucose, mean SD, and mean amplitude of glycemic excursions (MAGE).Results: Treatment with Basal Bolus and Basal Plus regimens resulted in similar mean daily glucose, hypoglycemia, length of stay (LOS), and hospital complications (all P>.05). There were no differences in GV between treatment groups by Δ change (72.5 ± 36 vs. 69.3 ± 34 mg/dL), SD (38.5 ± 18 vs. 37.1 ± 16 mg/dL) and MAGE (67.5 ± 34 vs. 66.1 ± 39 mg/dL) (all P>.05). Surgery patients treated with Basal Bolus had higher GV compared to those treated with Basal Plus (Δ daily glucose and SD: P = .02, MAGE: P = .009), but no difference in GV was found between treatment groups for the general medicine patients (P>.05). Patients with hypoglycemia events had higher GV compared to subjects without hypoglycemia (P<.05), but no association was found between GV and hospital complications (P>.05).Conclusion: Treating hospitalized, non-ICU, diabetic patients with Basal Plus insulin regimen resulted in similar glucose control and GV compared to the standard Basal Bolus insulin regimen. Higher GV was not associated with hospital complications.Abbreviations:BG = blood glucoseCV= coefficient of variationGV= glycemic variabilityICU = intensive care unitLOS = length of stayMAGE = mean amplitude of glycemic excursionsSSI = sliding scale insulinT2D = type 2 diabetesTDD =total daily dose 相似文献

Objective: Ultraviolet (UV)-perception-type flame sensors detect gamma rays emitted from iodine 131 (131I). Explaining the possibility of flame sensor activation to patients when they receive 131I to treat Graves disease or other ablative purposes is important. We investigate the current situation of flame sensor activation after radioactive iodine (RAI) therapy.Methods: A total of 318 patients (65 males and 253 females) with Graves disease who received RAI therapy at our clinic between November 2007 and June 2014 participated in this study. Patients were given both written and oral explanations regarding the possibility of flame sensor activation. Participants were surveyed with a questionnaire. The following question was asked: “Did the fire alarm (flame sensor) go off when you used a restroom in places like shopping centers within a few days after your isotope therapy?” To those who answered “yes,” we asked where the fire alarm had gone off.Results: Of the 318 patients, 19 (6.0%) answered “yes,” 2 of whom were male while 17 were female. Of the 299 (94.0%) patients who answered “no,” 63 were male and 236 were female. As to the place of restroom sensor activation, shopping centers were reported by 9 patients; supermarkets by 5; airports by 2; and a bookstore, the Kyushu Shinkansen (bullet train), and a hospital by 1 each.Conclusion: Explaining to patients the possibility of flame sensor activation after RAI therapy is important to avoid some complications, especially in security-sensitive areas.Abbreviations:131I = iodine 131RAI = radioactive iodineUV = ultra-violet 相似文献

Objective: Review available data on adjunctive therapies for type 1 diabetes (T1D), with a special focus on newer antihyperglycemic agents.Methods: Published data on hypoglycemia, obesity, mortality, and goal attainment in T1D were reviewed to determine unmet therapeutic needs. PubMed databases and abstracts from recent diabetes meetings were searched using the term “type 1 diabetes” and the available and investigational sodium-glucose cotransporter (SGLT) inhibitors, glucagon-like peptide 1 (GLP-1) receptor agonists, dipeptidyl peptidase 4 inhibitors, and metformin.Results: The majority of patients with T1D do not meet glycated hemoglobin (A1C) goals established by major diabetes organizations. Hypoglycemia risks and a rising incidence of obesity and metabolic syndrome featured in the T1D population limit optimal use of intensive insulin therapy. Noninsulin antihyperglycemic agents may enable T1D patients to achieve target A1C levels using lower insulin doses, which may reduce the risk of hypoglycemia. In pilot studies, the SGLT2 inhibitor dapagliflozin and the GLP-1 receptor agonist liraglutide reduced blood glucose, weight, and insulin dose in patients with T1D. Phase 2 studies with the SGLT2 inhibitor empagliflozin and the dual SGLT1 and SGLT2 inhibitor sotagliflozin, which acts in the gut and the kidney, have demonstrated reductions in A1C, weight, and glucose variability without an increased incidence of hypoglycemia.Conclusion: Newer antihyperglycemic agents, particularly GLP-1 agonists, SGLT2 inhibitors, and dual SGLT1 and SGLT2 inhibitors, show promise as adjunctive treatment for T1D that may help patients achieve better glucose control without weight gain or increased hypoglycemia.Abbreviations:A1C = glycated hemoglobinBMI = body mass indexCI = confidence intervalDKA = diabetic ketoacidosisDPP-4 = dipeptidyl peptidase 4GLP-1 = glucagonlike peptide 1PYY = polypeptide tyrosine tyrosineSGLT = sodium-glucose cotransporterSGLT1 = sodium-glucose cotransporter 1SGLT2 = sodium-glucose cotransporter 2T1D = type 1 diabetesT2D = type 2 diabetesTDD = total daily dosage 相似文献

Objective: Individuals with diabetes are increasingly seeking pretravel advice, but updated professional recommendations remain scant. We performed a systematic review on diabetes management during air travel to summarize current recommendations, assess supporting evidence, and identify areas of future research.Methods: A systematic review of the English literature on diabetes management during air travel was undertaken utilizing PubMed and MEDLINE. Publications regarding general travel advice; adjustment of insulin and noninsulin therapies; and the use of insulin pumps, glucometers and subcutaneous glucose sensors at altitude were included. Gathered information was used to create an updated summary of glucose-lowering medication adjustment during air travel.Results: Sixty-one publications were identified, most providing expert opinion and few offering primary data (47 expert opinion, 2 observational studies, 2 case reports, 10 device studies). General travel advice was uniform, with increasing attention to preflight security. Indications for oral antihyperglycemic therapy adjustments varied. There were few recommendations on contemporary agents and on nonhypoglycemic adverse events. There was little consensus on insulin adjustment protocols, many antedating current insulin formulations. Most publications advocated adjusting insulin pump time settings after arrival; however, there was disagreement on timing and rate adjustments. Glucometers and subcutaneous glucose sensors were reported to be less accurate at altitude, but not to an extent that would preclude their clinical use.Conclusion: Recommendations for diabetes management during air travel vary significantly and are mostly based on expert opinion. Data from systematic investigation on glucose-lowering medication adjustment protocols may support the development of a future consensus statement.Abbreviations:CSII = continuous subcutaneous insulin infusion (device)DPP-4 = dipeptidyl peptidase 4EGA = error grid analysisGDH = glucose dehydrogenaseGOX = glucose oxidaseGLP1 = glucagon-like peptide-1NPH = neutral protamine HagedornSGLT2 = sodium-glucose cotransporter-2 相似文献

The diabetes insipidus mutation is displayed in homozygotes in the form of diabetes insipidus with water consumption from 30 to 100% of body weight per day. We developed two inbred sublines of the di/di Brattleboro rats as well as the recombinant inbred subline by integrating genes of August rats into the di/di mutant genome. Changes in the genetic background proved to have no effect on the quantitative parameters of the diabetes insipidus. The intensity of the secondary immune response and the content of tropomyosin in the medulla of the rat kidney can serve as additional marker traits of the di/di genotype. 相似文献

Objective: Abnormalities of water and sodium balance, including diabetes insipidus and the syndrome of inappropriate antidiuretic hormone (SIADH), are common complications of transsphenoidal surgery. Postoperative practice patterns vary among clinicians, and no consensus guidelines exist to direct their monitoring and management. We aimed to identify and compare practice patterns regarding the evaluation and management to these postoperative complications.Methods: A questionnaire was utilized to capture demographic data and practice habits in the postoperative setting. Respondents were members of the Pituitary Society, an international organization comprised of clinicians and researchers dedicated to the study of pituitary disease.Results: Eighty-six respondents completed at least part of the survey. The geographic distribution of respondents was roughly even between American and non-American practitioners. The majority of respondents practiced at academic institutions (67.4%), worked in multidisciplinary teams (88.4%), and possessed significantly greater than 10 years of clinical experience (71%). Compared to non-American practitioners, American practitioners described a shorter length of stay postoperatively (P<.001) and prescribed more restrictive volume recommendations for postoperative SIADH (P = .0035). Early career clinicians (less than 10 years in practice) checked first postoperative sodium level earlier than later career clinicians (P = .010).Conclusion: Water and sodium dysregulation are common following transsphenoidal surgery, but their management is not well-standardized in clinical practice. We created a questionnaire to define and compare practice patterns. Most respondents practice in academic settings in multidisciplinary teams. The length of clinical experience did not significantly impact practice habits. Practice location influenced length of stay postoperatively and fluid restriction in SIADH.Abbreviations: AVP = arginine vasopressin; DI = diabetes insipidus; LOS = length of stay; SIADH = syndrome of inappropriate antidiuretic hormone 相似文献

Objective: We examined whether the “Dexamethasone Stress Test” exhibits the requisite high predictive ability to identify individuals highly prone to develop type 2 diabetes mellitus (T2DM).Methods: Seven years ago, we administered an oral glucose tolerance test (OGTT) to 33 individuals without T2DM and repeated the OGTT 24 hours after a single oral dose of 8 mg dexamethasone (Dex); all participants had a first-degree relative with T2DM, and close to half had prediabetes. We calculated receiver operating characteristic (ROC) curves for all parameters derived from the OGTT before and after Dex in individuals who subsequently developed diabetes compared to individuals who did not.Results: At 7 years of follow-up, 9 individuals had developed T2DM, while 24 remained without diabetes. None of the OGTT-derived parameters before administration of Dex had an area under the ROC curve of >0.8. However, 24 hours after Dex, three parameters, including fasting plasma insulin, homeostatic model assessment–insulin resistance, and 2-hour plasma glucose level, exhibited areas under the ROC curves of 0.84, 0.86, and 0.92, respectively.Conclusion: The Dexamethasone Stress Test appears to be a good to excellent test in identifying individuals highly prone to develop T2DM.Abbreviations: AUC = area under the curve; Dex = dexamethasone; HOMA-IR = homeostatic model assessment–insulin resistance; NGT = normal glucose tolerance; OGTT = oral glucose tolerance test; PreDiab = prediabetes; ROC = receiver operating characteristic; T2DM = type 2 diabetes mellitus 相似文献
