ObjectiveTo investigate the reasons for the increased risk of cardiovascular events and mortality in individuals with type 2 diabetes mellitus.MethodsFrom January 1990 to March 2008, literature relevant to low-density lipoprotein (LDL) and highdensity lipoprotein (HDL) cholesterol, hemoglobin A1c, acute hyperglycemia, postprandial hyperglycemia, systolic blood pressure, insulin resistance, endothelial dysfunction, microalbuminuria, diabetic cardiomyopathy, left ventricular hypertrophy, function inhibitors of the renin-angiotensin system and sympathetic nervous system, statins, and antiplatelet therapy as related to cardiac events and mortality in type 2 diabetic patients was reviewed.ResultsIncreased numbers of cardiac events and mortality in type 2 diabetes are associated with low HDL and high LDL cholesterol, high hemoglobin A1c, and high systolic blood pressure. Acute hyperglycemia, postprandial hyperglycemia, and possibly use of traditional sulfonylureas also increase incidence of cardiac events and mortality. The presence of microalbuminuria signifies endothelial dysfunction and an increased risk of cardiac events. Hypertension should be treated to goals that are lower in the diabetic patient with multiple therapies, which include suppressors of the renin-angiotensin and sympathetic nervous systems. Decreased improvement in outcomes for the diabetic patient with cardiovascular disease may be accounted for by the failure to treat insulin resistance and ventricular dysfunction. The high incidence of heart failure in the diabetic patient is due to the toxic triad of diabetic cardiomyopathy, left ventricular hypertrophy, and extensive coronary artery disease.ConclusionHigh risk of cardiovascular events, heart failure, and mortality in type 2 diabetes can be lowered with risk factor reduction and therapies that prevent or improve ventricular function.

Objective: To determine the relationship between family history of diabetes mellitus (DM) and diabetic ketoacidosis (DKA) recurrence in youth with established type 1 diabetes mellitus (T1DM).Methods: We performed a retrospective chart review of patients with DKA admitted to a pediatric hospital between January, 2009, and December, 2014. We compared patients with recurrent (≥2 admissions) and nonrecurrent DKA (1 admission) and investigated patient level factors, including family history, that may be associated with DKA recurrence in pediatric patients with established T1DM.Results: Of the 131 subjects in the study, 51 (39%) subjects were in the recurrence group. Age ≥15 years old, public health insurance, and family history of T1DM or type 2 diabetes mellitus were associated with recurrent DKA admissions in both univariable and multivariable analyses. Family history was associated with DKA recurrence, with an incidence rate ratio of 1.5 (95% confidence interval = 1.0 to 2.3; P = .03). The association was not explained by type of familial diabetes, first degree relative status, or whether the family member lived in the household.Conclusion: Recognition that a positive family history of DM may be associated with a higher risk for DKA recurrence in patients with established T1DM may allow for targeted education and focus on a previously unidentified population at increased risk for DKA. Understanding the mechanism underlying the effect of family history of diabetes on the rates of DKA in patients with established T1DM may allow for improved identification and education of patients who may be at risk for DKA recurrence.Abbreviations: CI = confidence interval; DKA = diabetic ketoacidosis; EHR = electronic health record; IBD = inflammatory bowel disease; IRR = incidence rate ratio; T1DM = type 1 diabetes mellitus; T2DM = type 2 diabetes mellitus 相似文献

ObjectiveTo present a case of management of refractory hypoglycemia due to malignant insulinoma with use of everolimusresulting in recurrent insulin-requiring diabetes.MethodsThis report describes a case of a nonresectable malignant insulinoma in a 78-year-old patient with long-standing type 2 diabetes mellitus. Endogenous hyperinsulinism was confirmed by a fasting test, which revealed a glucose level of 35 mg/dL and an insulin value of 23.7 μIU/mL. Endoscopic ultrasonography, magnetic resonance imaging, and computed tomography identified a pancreatic mass, infiltration of the superior mesenteric vein, and metastatic lesions in the liver.ResultsAfter chemoembolization of the metastatic lesions, hypoglycemia recurred, despite combined treatment with somatostatin analogues, dexamethasone, and diazoxide. Everolimus, an orally administered mammalian target of rapamycin, was used at a daily dose of 5 mg. After 6 months, the hypoglycemia was controlled, and the patient presented with a C-peptide level of 0.2 ng/mL and secondary hyperglycemia that necessitated insulin treatment.ConclusionThe orally administered drug everolimus controlled hypoglycemia due to a malignant insulinoma in a patient with prior insulinrequiring diabetes. Secondary hyperglycemia was an acceptable drug effect (to the patient and managing physicians), in light of the complex and often poorly tolerated treatments available for this rare condition.

ObjectiveTo report a case of Mauriac syndrome in a young child with poorly controlled type 1 diabetes mellitus.MethodsWe describe the typical features of Mauriac syndrome and review the clinical, laboratory, and ultrasound findings and follow-up results in our current patient.ResultsHepatomegaly, growth impairment, and cushingoid features characterize Mauriac syndrome. Most frequently, it is seen in adolescents and young adults with a history of poor glycemic control. In our current patient, a 3-year-old boy with type 1 diabetes mellitus of 2 years’ duration, Mauriac syndrome developed in the context of a disrupted social environment. His liver enzyme derangement, hepatomegaly, and growth improved once euglycemia was achieved.ConclusionAlthough Mauriac syndrome is currently uncommon, close monitoring of children with type 1 diabetes is important to maintain optimal glycemic control and prevent such an occurrence.

ObjectiveTo review the current literature on posttransplant diabetes mellitus after hematopoietic stem cell transplantation, including its epidemiologic features, transplant-related risk factors, and treatment.MethodsA literature search was conducted in PubMed for articles on diabetes mellitus after hematopoietic stem cell transplantation and effects of immunosuppressants on glucose metabolism.ResultsWithin 2 years after hematopoietic stem cell transplantation, up to 30% of patients may have diabetes. Although some of these cases resolve, the rates of diabetes and metabolic syndrome remain elevated in comparison with those in the nontransplant patient population during long-term follow-up. Traditional risk factors for diabetes as well as features related to the transplantation process, including immunosuppressive medications, are associated with posttransplant diabetes. Cardiovascular risk also appears to be increased in this population. Limited data are available on hypoglycemic agents for posttransplant diabetes; thus, treatment decisions must be based on safety, efficacy, and tolerability, with consideration of each patient’s transplant-related medications and comorbidities.ConclusionTreatment of diabetes mellitus in patients who have undergone hematopoietic stem cell transplantation necessitates attention to the posttransplant medication regimen and clinical course. Although no guidelines specific to treatment of posttransplant diabetes in this patient population currently exist, treatment to goals similar to those for nontransplant patients with diabetes should be considered in an attempt to help reduce long-term morbidity and mortality.

ObjectiveTo review the clinical manifestations and current treatment options for diabetic neuropathies, one of the most common complications of diabetes mellitus.MethodsWe performed a MEDLINE search of the English-language literature using a combination of words (diabetic neuropathy, diabetic autonomic neuropathy, diagnosis and treatment) to identify original studies, consensus statements, and reviews on diabetic neuropathies published in the past 25 years. Emphasis was placed on clinical manifestations of distal polyneuropathy and its treatment, especially new therapies.ResultsDistal symmetric polyneuropathy, the most common form of diabetic neuropathy, usually involves small and large nerve fibers. Small-nerve fiber neuropathy often presents with pain and loss of intraepidermal nerve fibers, but without objective signs or electrophysiologic evidence of nerve damage. This type of neuropathy is a component of impaired glucose tolerance and the metabolic syndrome. The greatest risk from small-fiber neuropathy is foot ulceration and subsequent gangrene and amputation. Large-nerve fiber neuropathy produces numbness, ataxia, and incoordination, thus impairing activities of daily living and causing falls and fractures. Successfully treating diabetic neuropathy requires addressing the underlying pathogenic mechanisms, treating symptoms to improve quality of life, and preventing progression and complications of diabetes mellitus. Two new drugs, duloxetine hydrochloride and pregabalin, have recently been approved for treatment of neuropathic pain associated with diabetes mellitus.ConclusionSymptomatic therapy has become available and newer and better treatment modalities, based on etiologic factors, are being explored with potential for clinically significant reduction of morbidity and mortality. Preventive strategies and patient and physician education still remain key factors in reducing complication rates and mortality. (Endocr Pract. 2007;13:550-566) 相似文献

ObjectiveTo describe the clinical manifestations of insulin allergy and explain a systematic management approach.MethodsWe present the clinical, laboratory, and pathologic findings of a type 1 diabetic patient with allergy to subcutaneous insulin and briefly review the related literature.ResultsAn 18-year old woman with type 1 diabetes mellitus had an insulin allergy and developed subcutaneous nodules after insulin administration. Human and analogue insulins were used, but painful nodule formation persisted. Treatment with antihistamines, steroids, and omalizumab and insulin desensitization were ineffective. The patient required pancreatic transplant because glycemic control could not be achieved due to the insulin allergy.ConclusionsInsulin allergy is not a common condition and can be challenging in patients with type 1 diabetes. Therefore, identifying patients with true insulin allergy and applying a stepwise approach to their treatment is important. (Endocr Pract. 2011;17:91-94) 相似文献

ObjectiveTo identify the factors that influence recurrent (one or more previous episodes) diabetic ketoacidosis (DKA), which we refer to as recurrent DKA, in two private community teaching hospitals.MethodsRetrospective chart review of the demographics, diabetes treatment regimens, diabetes education, medical comorbidities, medical insurance status, and mental illness/psychosocial factors of 80 patients with recurrent DKA who were admitted to the resident teaching services at two Birmingham, Alabama community teaching hospitals, Trinity Medical Center (TMC) and Princeton Baptist Medical Center (PBMC), between May 2006 and May 2012.ResultsThe average number of admissions for recurrent DKA was 2.5 per patient. Eighty-four percent of the episodes of recurrent DKA were due to omission of insulin; 44% of patients reported omission of insulin because of illness and 40% stopped insulin for unknown reasons. Medical illnesses, including infection, accounted for only 31% of recurrent DKA admissions.ConclusionOmission of insulin is the major cause of recurrent DKA. Psychosocial and socioeconomic factors contribute to poor adherence to therapy. Identifying these factors and instituting appropriate interventions may reduce the incidence of recurrent DKA.

Objective: The cardiovascular outcomes of insulin detemir in patients with type 2 diabetes mellitus (T2DM) after acute coronary syndrome (ACS) or acute ischemic stroke (AIS) are unclear. The aim of our real-life cohort study was to evaluate the cardiovascular outcomes of insulin detemir (IDet) versus insulin glargine (IGlar) in T2DM patients after ACS or AIS.Methods: A retrospective cohort study was conducted between June 1, 2005, and December 31, 2013, utilizing the Taiwan National Health Insurance Research Database. A total of 3,129 ACS or AIS patients were eligible for the analysis. Clinical outcomes were evaluated by comparing 1,043 subjects receiving IDet with 2,086 propensity score-matched subjects who received IGlar. The primary composite outcome included cardiovascular (CV) death, nonfatal myocardial infarction (MI) and nonfatal stroke.Results: The primary composite outcome occurred in 322 patients (30.9%) in the IDet group and 604 patients (29.0%) in the IGlar group (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.95 to 1.32) with a mean follow-up of 2.4 years. No significant differences were observed for CV death (HR, 1.09; 95% CI, 0.86 to 1.38), nonfatal MI (HR, 0.88; 95% CI, 0.66 to 1.19), and nonfatal stroke (HR, 1.15; 95% CI, 0.97 to 1.35). There were similar risks of all-cause mortality, hospitalization for heart failure and revascularization between the IDet group and the IGlar group (P = .647, .115, and .390 respectively).Conclusion: Compared with IGlar, in T2DM patients after ACS or AIS, IDet was not associated with increased risks of CV death, nonfatal MI, or nonfatal stroke.Abbreviations: ACS = acute coronary syndrome; AIS = acute ischemic stroke; ASCVD = atherosclerotic cardiovascular disease; CI = confidence interval; CV = cardiovascular; DKA = diabetic ketoacidosis; HHF = hospitalization for heart failure; HHS = hyperosmolar hyperglycemic state; HR = hazard ratio; IDet = insulin detemir; IGlar = insulin glargine; MI = myocardial infarction; NHIRD = National Health Insurance Research Database; PCI = percutaneous coronary intervention; PSM = propensity score matching; T2DM = type 2 diabetes mellitus 相似文献

Objective: To characterize the relationship between diabetic retinopathy (DR) and diabetic nephropathy (DN) in Chinese patients and to determine whether the severity of DR predicts end-stage renal disease (ESRD).Methods: Bilateral fundic photographs of 91 Chinese type 2 diabetic patients with biopsy-confirmed DN, not in ESRD stage, were obtained at the time of renal biopsy in this longitudinal study. The baseline severity of DR was determined using the Lesion-aware Deep Learning System (RetinalNET) in an open framework for deep learning and was graded using the Early Treatment Diabetic Retinopathy Study severity scale. Cox proportional hazard models were used to estimate the hazard ratio (HR) for the effect of the severity of diabetic retinopathy on ESRD.Results: During a median follow-up of 15 months, 25 patients progressed to ESRD. The severity of retinopathy at the time of biopsy was a prognostic factor for progression to ESRD (HR 2.18, 95% confidence interval 1.05 to 4.53, P = .04). At baseline, more severe retinopathy was associated with poor renal function, and more severe glomerular lesions. However, 30% of patients with mild retinopathy and severe glomerular lesions had higher low-density lipo-protein-cholesterol and more severe proteinuria than those with mild glomerular lesions. Additionally, 3% of patients with severe retinopathy and mild glomerular changes were more likely to have had diabetes a long time than those with severe glomerular lesions.Conclusion: Although the severity of DR predicted diabetic ESRD in patients with type 2 diabetes mellitus and DN, the severities of DR and DN were not always consistent, especially in patients with mild retinopathy or microalbuminuria.Abbreviations: CI = confidence interval; DM = diabetic mellitus; DN = diabetic nephropathy; DR = diabetic retinopathy; eGFR = estimated glomerular filtration rate; ESRD = end-stage renal disease; HbA1c = hemoglobin A1c; HR = hazard ratio; NPDR = nonproliferative diabetic retinopathy; PDR = proliferative diabetic retinopathy; SBP = systolic blood pressure; T2DM = type 2 diabetes mellitus; VEGF = vascular endothelial growth factor 相似文献

Despite increased risk of a recurrent stroke following a minor stroke, information is minimal regarding the interaction between injurious mild cerebral ischemic episodes and the possible treatments which might be effective. The aim of the current study was to investigate recurrent ischemic stroke and whether resveratrol, a nutritive polyphenol with promising cardio- and neuro- protective properties, could ameliorate the associated brain damage. Experiments in adult rats demonstrated that a mild ischemic stroke followed by a second mild cerebral ischemia exacerbated brain damage, and, daily oral resveratrol treatment after the first ischemic insult reduced ischemic cell death with the recurrent insult (P<0.002). Further investigation demonstrated reduction of both inflammatory changes and markers of oxidative stress in resveratrol treated animals. The protection observed with resveratrol treatment could not be explained by systemic effects of resveratrol treatment including effects either on blood pressure or body temperature measured telemetrically. Investigation of resveratrol effects on the blood-brain barrier in vivo demonstrated that resveratrol treatment reduced blood-brain barrier disruption and edema following recurrent stroke without affecting regional cerebral blood flow. Investigation of the mechanism in primary cell culture studies demonstrated that resveratrol treatment significantly protected endothelial cells against an in vitro ‘ischemia’ resulting in improved viability against oxygen and glucose deprivation (39.6±6.6% and 81.3±9.5% in vehicle and resveratrol treated cells, respectively). An inhibition of nitric oxide synthesis did not prevent the improved cell viability following oxygen glucose deprivation but SIRT-1 inhibition with sirtinol partially blocked the protection (P<0.001) suggesting endothelial protection is to some extent SIRT-1 dependent. Collectively, the results support that oral resveratrol treatment provides a low risk strategy to protect the brain from enhanced damage produced by recurrent stroke which is mediated in part by a protective effect of resveratrol on the endothelium of the cerebrovasculature. 相似文献

ObjectiveTo determine the frequency of elevated creatine kinase (CK) levels among patients with diabetes mellitus and to determine how often elevated CK is attributable to primary myopathy.MethodsIn this prospective study, we investigated how often CK, aspartate aminotransferase, alanine aminotransferase, and resting lactate were elevated among consecutive diabetic patients attending our clinic. Those with elevated CK values were offered a neurologic workup.ResultsNinety-nine patients with diabetes mellitus, aged 19 to 87 years, were assessed between May 2008 and April 2010. Seven patients had type 1 diabetes and 92 patients had type 2 diabetes. CK, aspartate aminotransferase, alanine aminotransferase, and resting lactate were elevated in 19 of 99, 25 of 99, 22 of 99, and 24 of 98 patients, respectively. Eleven of 19 patients with increased CK were self-injecting insulin. Ten of 24 patients with elevated serum lactate took metformin. Seven of 19 patients with elevated CK consented to neurologic workup. Two of the 7 had elevated resting lactate. In all 7 patients, the findings from neurologic investigation were indicative of a metabolic defect and further diagnostic evaluation was recommended.ConclusionsIn diabetic patients attending our clinic, elevated CK levels occur in one-fifth and lactacidemia occurs in one-quarter. Elevated CK levels are attributable to a primary metabolic myopathy in most cases. Elevated CK levels in the setting of diabetes mellitus require further neurologic evaluation.

Objective: To investigate the prevalence and clinical characteristics of ketosis-prone type 2 diabetes (KPD) in Chinese patients with young-onset diabetes.Methods: A total of 238 young diabetic patients were recruited from our inpatient department from January 1, 2012, to December 28, 2014. KPD was defined as diabetes without precipitating illness and with the presence of ketosis or diabetic ketoacidosis in the absence of autoantibodies at the time of diagnosis. We reviewed the clinical characteristics and disease progression of this group of patients.Results: Eighteen patients fulfilled the criteria for KPD, and the prevalence of patients with KPD was 7.6%. The mean (SD) age of the KPD group at the time of diagnosis of diabetes was 27.6 (4.85) years, and these patients were predominantly male (male to female ratio, 8:1) and had a high proportion of obesity and new-onset diabetes and a strong family history of diabetes. β-Cell function in the KPD group was intermediate between type 1 and type 2 diabetes. Patients with KPD had the highest levels of glycated hemoglobin, triglycerides, total cholesterol, and free fatty acids and the lowest levels of high-density lipoprotein. After 3 to 12 months of follow-up, 17 of 18 patients with KPD (94.4%) were able to discontinue insulin therapy, and 11 patients (61.1%) were managed with diet or exercise alone.Conclusion: KPD patients accounted for 7.6% of the diabetic patients requiring admission to a large urban hospital in China, with an age of onset of diabetes of ≤35 years. These patients are more likely to be male, have abnormal lipid metabolism, and have more reversible β-cell dysfunction.Abbreviations:BMI = body mass indexDKA = diabetic ketoacidosisGAD 65 = glutamate decarboxylase 65HbA 1c = glycated hemoglobinICAs = islet-cell antibodiesKPD = ketosis-prone type 2 diabetes mellitusLADA = latent autoimmune diabetes in an adultMIDD = maternally inherited diabetes and deafnessMODY = maturityonset diabetes of the youngT1DM = type 1 diabetes mellitusT2DM = type 2 diabetes mellitus 相似文献

Introduction
Diabetic macular edema (DME) is an important cause of vision loss. England has a national systematic photographic retinal screening programme to identify patients with diabetic eye disease. Grading retinal photographs according to this national protocol identifies surrogate markers for DME. We audited a care pathway using a spectral-domain optical coherence tomography (SDOCT) clinic to identify macular pathology in this subset of patients.Methods
A prospective audit was performed of patients referred from screening with mild to moderate non-proliferative diabetic retinopathy (R1) and surrogate markers for diabetic macular edema (M1) attending an SDOCT clinic. The SDOCT images were graded by an ophthalmologist as SDOCT positive, borderline or negative. SDOCT positive patients were referred to the medical retina clinic. SDOCT negative and borderline patients were further reviewed in the SDOCT clinic in 6 months.Results
From a registered screening population of 17 551 patients with diabetes mellitus, 311 patients met the inclusion criteria between (March 2008 and September 2009). We analyzed images from 311 patients’ SDOCT clinic episodes. There were 131 SDOCT negative and 12 borderline patients booked for revisit in the OCT clinic. Twenty-four were referred back to photographic screening for a variety of reasons. A total of 144 were referred to ophthalmology with OCT evidence of definite macular pathology requiring review by an ophthalmologist.Discussion
This analysis shows that patients with diabetes, mild to moderate non-proliferative diabetic retinopathy (R1) and evidence of diabetic maculopathy on non-stereoscopic retinal photographs (M1) have a 42.1% chance of having no macular edema on SDOCT imaging as defined by standard OCT definitions of DME when graded by a retinal specialist. SDOCT imaging is a useful adjunct to colour fundus photography in screening for referable diabetic maculopathy in our screening population. 相似文献16.

BackgroundThe association between diabetes mellitus (DM) and prognosis of minor stroke is unclear. The aim of this study is to investigate whether DM contributes to the prognosis of minor stroke or its specific subtype.MethodsAll minor ischemic stroke patients were derived from the China National Stroke Registry and classified into 5 subtypes according to the TOAST (Trial of Org 10172 in Acute Stroke Treatment) criteria. DM was defined as either self-reported physician diagnosis of diabetes or use of hypoglycemic medications during hospitalization or at discharge. Patients were followed up for 1 year for clinical outcomes of recurrent stroke, death and functional outcome. Poor functional outcomes were defined as a score of 2–6 for modified Rankin Score. Associations between DM and prognosis of minor stroke and its subtypes were analyzed by univariable and multivariable logistic regression.ResultsOf 4,548 patients with minor stroke, 1,230(27.0%) patients had DM, 1,038(22.8%) had poor outcomes and 570(13.0%) of 4,401 patients had recurrent stroke at 1 year. In multivariable analyses, DM were significantly associated with 1-year stroke recurrence (Odds Ratio [OR], 1.31; 95% confidence interval [CI]: 1.08–1.59) and poor outcome (OR, 1.51; 95%CI: 1.28–1.77). Among the subtypes of minor stroke, DM was only significantly associated with 1-year stroke recurrence (OR, 1.63; 95%CI: 1.07–2.50) and poor outcome (OR, 1.73; 95%CI: 1.22–2.45) in the small-artery occlusion subtype.ConclusionsDM significantly increased the risk of stroke recurrence and poor outcome in the small-artery occlusion subtype, but not in other subtypes of minor stroke. 相似文献

ObjectiveTo report a rare case of diabetes caused by type B insulin resistance due to development of insulin receptor autoantibodies during treatment of hepatitis C with interferon-a and ribavirin.MethodsClinical and laboratory findings in the case are presented. The literature on type B insulin resistance and interferon-induced autoimmunity is reviewed.ResultsA 55-year-old African American man with hepatitis C was treated with interferon and ribavirin. Eight months later, he presented with rapid onset of hyperglycemia, profound weakness, and weight loss. Severe hyperglycemia persisted despite insulin infusion rates as high as 125 U/h. The presence of insulin receptor autoantibodies was confirmed by immunoprecipitation of recombinant human insulin receptor with patient serum. Assays for autoantibodies to islet cell antigens and glutamic acid decarboxylase were negative. The interferon and ribavirin were discontinued. His insulin requirement spontaneously declined to low levels over a 6-month period. Two years after discharge of the patient, insulin receptor autoantibodies could no longer be demonstrated in his serum. He remains euglycemic and is no longer taking insulin.ConclusionThis case demonstrates that type B insulin resistance can occur as a complication of interferon-α therapy. To our knowledge, this is the first reported case in the United States of type B insulin resistance with development of insulin receptor autoantibodies during treatment with interferon-a.

More than 65% of patients with diabetes mellitus die from cardiovascular disease or stroke. Hyperglycemia, due to either reduced insulin secretion or reduced insulin sensitivity, is the hallmark feature of diabetes mellitus. Vascular dysfunction is a distinctive phenotype found in both types of diabetes and could be responsible for the high incidence of stroke, heart attack, and organ damage in diabetic patients. In addition to well-documented endothelial dysfunction, Ca2+ handling alterations in vascular smooth muscle cells (VSMCs) play a key role in the development and progression of vascular complications in diabetes. VSMCs provide not only structural integrity to the vessels but also control myogenic arterial tone and systemic blood pressure through global and local Ca2+ signaling. The Ca2+ signalosome of VSMCs is integrated by an extensive number of Ca2+ handling proteins (i.e. channels, pumps, exchangers) and related signal transduction components, whose function is modulated by endothelial effectors. This review summarizes recent findings concerning alterations in endothelium and VSMC Ca2+ signaling proteins that may contribute to the vascular dysfunction found in the diabetic condition. 相似文献

ObjectiveTo describe the first case of syndrome of inappropriate antidiuretic hormone secretion with lifethreatening hyponatremia due to rosiglitazone therapy.MethodsWe describe the clinical, laboratory, and imaging findings of the study patient.ResultsAn 89-year-old woman with a 5-year history of type 2 diabetes mellitus was admitted to the emergency department because of unconsciousness. She had reported generalized weakness for 15 days and nausea and vomiting for 3 days. Findings from laboratory analysis showed severe hyponatremia (sodium, 110 mEq/L). She had normal renal, cardiac, and adrenal function, and she did not have edema or volume depletion. The cause of hyponatremia was syndrome of inappropriate antidiuretic hormone secretion. We did not find any cause for her condition other than rosiglitazone, an antihyperglycemic drug that is increasingly being used in patients with type 2 diabetes mellitus. According to her medical history, rosiglitazone was prescribed 1 month previously after withdrawal of gliclazide. We stopped the rosiglitazone and administered hypertonic saline infusion to treat the hyponatremia. Saline infusion was stopped and blood sodium levels were stabilized in the normal range after 2 days. The patient’s plasma sodium concentration has remained in the reference range at follow-up visits.ConclusionsThis is the first reported case of syndrome of inappropriate antidiuretic hormone secretion as an adverse effect of rosiglitazone, and this drug should possibly be considered for addition to the list of drugs that cause this condition.
