RESUMEN

BACKGROUND: We examined in persons with type 2 diabetes (T2D) whether the use of insulin and the risk of serious hypoglycemic events with insulin is higher in persons with more advanced CKD. METHODS: In a national cohort of 855,133 veterans with T2D seen at Veteran Affairs clinics between Jan 1, 2008 and December 31, 2010 with at least two serum creatinine measurements, we defined insulin use from pharmacy records and serious hypoglycemic events by ICD-9/10 codes from emergency room visits or hospitalizations that occurred until December 31, 2016. RESULTS: Mean age was 66 ± 11 years and 97% were men. Mean baseline eGFR was 73 ± 22 ml/min/1.73 m2. In a multivariable Cox regression model of those without insulin use at baseline (N = 653,200), compared to eGFR ≥90 group, eGFR < 30 group had higher hazard (HR 1.80, 95% CI 1.74 to 1.88) of subsequent insulin use. In a multivariable Cox model with propensity score matching for baseline insulin use (N = 305,570), both insulin use (HR 2.34, 95% CI 2.24 to 2.44) and advanced CKD (HR 2.28, 95% CI 2.07 to 2.51 for comparison of eGFR < 30 to eGFR ≥90 ml/min/1.73 m2 groups) were associated with increased risk of subsequent serious hypoglycemic events. CONCLUSIONS AND RELEVANCE: In T2D, more advanced CKD was associated with greater insulin use. Both insulin use and advanced CKD were risk factors for serious hypoglycemic events. The safety of insulin compared to newer glycemic agents in more advanced CKD needs further study.

RESUMEN

BACKGROUND: The previously published results of the Systolic Blood Pressure Intervention Trial showed that among participants with hypertension and an increased cardiovascular risk, but without diabetes, the rates of cardiovascular events were lower among those who were assigned to a target systolic blood pressure of less than 120 mm Hg (intensive treatment) than among those who were assigned to a target of less than 140 mm Hg (standard treatment). Whether such intensive treatment affected patient-reported outcomes was uncertain; those results from the trial are reported here. METHODS: We randomly assigned 9361 participants with hypertension to a systolic blood-pressure target of less than 120 mm Hg or a target of less than 140 mm Hg. Patient-reported outcome measures included the scores on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of the Veterans RAND 12-Item Health Survey, the Patient Health Questionnaire 9-item depression scale (PHQ-9), patient-reported satisfaction with their blood-pressure care and blood-pressure medications, and adherence to blood-pressure medications. We compared the scores in the intensive-treatment group with those in the standard-treatment group among all participants and among participants stratified according to physical and cognitive function. RESULTS: Participants who received intensive treatment received an average of one additional antihypertensive medication, and the systolic blood pressure was 14.8 mm Hg (95% confidence interval, 14.3 to 15.4) lower in the group that received intensive treatment than in the group that received standard treatment. Mean PCS, MCS, and PHQ-9 scores were relatively stable over a median of 3 years of follow-up, with no significant differences between the two treatment groups. No significant differences between the treatment groups were noted when participants were stratified according to baseline measures of physical or cognitive function. Satisfaction with blood-pressure care was high in both treatment groups, and we found no significant difference in adherence to blood-pressure medications. CONCLUSIONS: Patient-reported outcomes among participants who received intensive treatment, which targeted a systolic blood pressure of less than 120 mm Hg, were similar to those among participants who received standard treatment, including among participants with decreased physical or cognitive function.

RESUMEN

AIMS: Arterial stiffness increases with both advancing age and chronic kidney disease (CKD) and may contribute to kidney function decline, but evidence is inconsistent. We hypothesized that greater baseline arterial stiffness (assessed as pulse pressure (PP) and carotid-femoral pulse-wave velocity CFPWV)) was independently associated with kidney disease progression over the follow-up period (3.8 years) in the Systolic Blood Pressure Intervention Trial (SPRINT). MATERIALS AND METHODS: 8,815 SPRINT participants were included in the analysis of PP. 592 adults who participated in a SPRINT ancillary study that measured CFPWV were included in subgroup analyses. Cox proportional hazards analysis was used to examine the association between PP and time to kidney disease progression endpoints: (A) incident estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73m2 in non-CKD participants at baseline; (B) 50% decline in eGFR, initiation of dialysis, or transplant in those with baseline CKD. Mixed model analyses examined the association of baseline PP/CFPWV with follow-up eGFR. RESULTS AND CONCLUSION: Mean ± SD age was 68 ± 10 years, baseline PP was 62 ± 14 mmHg, and CFPWV was 10.8 ± 2.7 m/s. In the fully adjusted model, PP ≥ median was associated with an increased hazard of kidney disease progression endpoints (HR: 1.93 (1.43 - 2.61)). The association remained significant in individuals without (2.05 (1.47 - 2.87)) but not with baseline CKD (1.28 (0.55 - 2.65)). In fully adjusted models, higher baseline PP associated with eGFR decline (p < 0.0001 (all, CKD, non-CKD)), but baseline CFPWV did not. Among older adults at high risk for cardiovascular events, baseline PP was associated with kidney disease progression.

RESUMEN

AIMS/HYPOTHESIS: We aimed to determine the persistence of glycaemic control 1 year after a limited period of intensive glycaemic management of type 2 diabetes. METHODS: 4119 ACCORD Trial participants randomised to target HbA1c <6.0% (42 mmol/mol) for 4.0 ± 1.2 years were systematically transitioned to target HbA1c 7.0-7.9% (53-63 mmol/mol) and followed for an additional 1.1 ± 0.2 years. Characteristics of participants with HbA1c <6.5% (48 mmol/mol) or ≥6.5% at transition were compared. Changes in BMI and glucose-lowering medications were compared between those ending with HbA1c <6.5% vs ≥6.5%. Poisson models were used to assess the independent effect of attaining HbA1c <6.5% before transition on ending with HbA1c <6.5%. RESULTS: Participants with pre-transition HbA1c <6.5% were older with shorter duration diabetes and took less insulin but more non-insulin glucose-lowering agents than those with higher HbA1c. A total of 823 participants achieved a final HbA1c <6.5%, and had greater post-transition reductions in BMI, insulin dose and secretagogue and acarbose use than those with higher HbA1c (p < 0.0001). HbA1c <6.5% at transition predicted final HbA1c <6.5% (crude RR 4.9 [95% CI 4.0, 5.9]; RR 3.9 [95% CI 3.2, 4.8] adjusted for demographics, co-interventions, pre-intervention HbA1c, BMI and glucose-lowering medication, and post-transition change in both BMI and glucose-lowering medication). Progressively lower pre-transition HbA1c levels were associated with a greater likelihood of maintaining a final HbA1c of <6.5%. Follow-up duration was not associated with post-transition rise in HbA1c. CONCLUSIONS/INTERPRETATION: Time-limited intensive glycaemic management using a combination of agents that achieves HbA1c levels below 6.5% in established diabetes is associated with glycaemic control more than 1 year after therapy is relaxed.

RESUMEN

BACKGROUND: There are few rigorous studies to confirm or refute the commonly cited concern that control of blood pressure to lower thresholds may result in an increased risk of falls and fractures. OBJECTIVE: To compare falls and fractures in participants with type 2 diabetes in the intensive (targeting a systolic blood pressure of < 120 mmHg) and standard (targeting a systolic blood pressure of < 140 mmHg) blood pressure control arms of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) randomized trial (N = 4,733). PARTICIPANTS: A subset of 3,099 participants self-reported annually on the occurrence of falls and non-spine fractures. Fractures were centrally adjudicated. MAIN MEASURES: The incidence of falls in the two treatment groups was compared using a random-effects negative binomial model, and fracture risk was compared using Cox proportional hazards models. KEY RESULTS: At enrollment in both groups, the mean age was 62 years, 44% were women, 25% were Black, and mean blood pressure was 138/75 mmHg. During follow-up, all classes of medications, particularly thiazide diuretics, were more commonly prescribed in the intensive group. After 1 year of follow-up, the mean systolic blood pressure was 133 ± 15 mmHg in the standard group and 119 ± 14 mmHg in the intensive group. The adjusted rate of falls did not differ in the intensive and standard groups (62.2/100 person-years vs. 74.1/100 person-years, RR = 0.84, 95% CI 0.54-1.29, p = 0.43). The risk of non-spine fractures was nonsignificantly lower in the intensive than in the standard blood pressure group (HR 0.79, 95% CI 0.62-1.01, p = 0.06). CONCLUSIONS: We conclude that intensive antihypertensive treatment that lowered mean systolic blood pressure to below 120 mmHg was not associated with an increased risk of falls or non-spine fractures in patients age 40 to 79 years with type 2 diabetes.

RESUMEN

INTRODUCTION: Type 2 diabetes is prevalent among US adults. Lifestyle interventions that modify health behaviours prevent or delay progression to diabetes among individuals at high risk. Despite the well-documented influence of individuals' social context on their health, evidence-based type 2 diabetes prevention interventions do not systematically incorporate participants' romantic partners. Involving partners of individuals at high risk for type 2 diabetes in primary prevention may improve engagement and outcomes of programmes. The randomised pilot trial protocol described in this manuscript will evaluate a couple-based lifestyle intervention to prevent type 2 diabetes. The objective of the trial is to describe the feasibility of the couple-based intervention and the study protocol to guide planning of a definitive randomised clinical trial (RCT). METHODS AND ANALYSIS: We used community-based participatory research principles to adapt an individual diabetes prevention curriculum for delivery to couples. This parallel two-arm pilot study will include 12 romantic couples in which at least one partner (ie, 'target individual') is at risk for type 2 diabetes. Couples will be randomised to either the 2021 version of the CDC's PreventT2 curriculum designed for delivery to individuals (six couples), or PreventT2 Together, the adapted couple-based curriculum (six couples). Participants and interventionists will be unblinded, but research nurses collecting data will be blinded to treatment allocation. Feasibility of the couple-based intervention and the study protocol will be assessed using both quantitative and qualitative measures. ETHICS AND DISSEMINATION: This study has been approved by the University of Utah IRB (#143079). Findings will be shared with researchers through publications and presentations. We will collaborate with community partners to determine the optimal strategy for communicating findings to community members. Results will inform a subsequent definitive RCT. TRIAL REGISTRATION NUMBER: NCT05695170.

RESUMEN

BACKGROUND/AIMS: The value of the Framingham equation in predicting cardiovascular risk in African Americans and patients with chronic kidney disease (CKD) is unclear. The purpose of the study was to evaluate whether the addition of CKD and race to the Framingham equation improves risk stratification in hypertensive patients. METHODS: Participants in the ALLHAT were studied. Those randomized to doxazosin, older than 74 years, and those with a history of coronary heart disease were excluded. Two risk stratification models were developed using Cox proportional hazards models in a two-thirds developmental sample. The first model included the traditional Framingham risk factors. The second model included the traditional risk factors plus CKD, defined by estimated glomerular filtration rate categories, and stratification by race (black vs non-black). The primary outcome was a composite of fatal coronary heart disease, nonfatal myocardial infarction, coronary revascularization, and hospitalized angina. RESULTS: There were a total of 19,811 eligible subjects. In the validation cohort, there was no difference in C-statistics between the Framingham equation and the ALLHAT model including CKD and race. This was consistent across subgroups by race and sex and among those with CKD. One exception was among Non-Black women where the C-statistic was higher for the Framingham equation (0.68 vs 0.65, P = .02). In addition, net reclassification improvement was not significant for any subgroup based on race and sex, ranging from -5.5% to 4.4%. CONCLUSION: The addition of CKD status and stratification by race does not improve risk prediction in high-risk hypertensive patients.

RESUMEN

BACKGROUND: Hypoglycemia is a common complication of diabetes treatment. This paper describes symptoms, predecessors, consequences and medications associated with the first episode of severe hypoglycemia among ACCORD participants with type 2 diabetes, and compares these between intensive (Int: goal A1C <6.0%) and standard (Std, goal A1C 7-7.9%) glycemia intervention groups. METHODS: Information about symptoms, antecedents, and consequences was collected at the time participants reported an episode of severe hypoglycemia. Data on medications prescribed during the clinical trial was used to determine the association of particular diabetes drug classes and severe hypoglycemia. RESULTS: The most frequently reported symptoms in both glycemia group were weakness/fatigue (Int 29%; Std 30%) and sweating (Int 26%; Std 27%), followed by confusion/disorientation (Int 22%; Std 29%) and shakiness (Int 21%; Std 19%). Approximately half of all events were preceded by a variation in food intake (Int 48%; Std 58%). The most common consequences were confusion (Int 37%; Std 34%), loss of consciousness (Int 25%; Std 25%), and hospitalization (Int 18%; Std 24%). The highest rates of hypoglycemia were found among those participants treated with insulin only (Int 6.09/100 person yrs; Std 2.64/100 person yrs) while the lowest were among those prescribed oral agents only (Int 1.93/100 person yrs; Std 0.20/100 person yrs). CONCLUSIONS: Severe hypoglycemia episodes were frequently preceded by a change in food intake, making many episodes potentially preventable. Symptoms of confusion/disorientation and loss of consciousness were frequently seen. The highest rates of hypoglycemia were seen with prescription of insulin, either alone or in combination with other medications. CLINICAL TRIAL REGISTRATION: Number: NCT00000620.

RESUMEN

Dual training in Internal Medicine-Pediatrics (MedPeds) was recognized by the American Board of Medical Specialties in 1967. Residents complete 24 months each in Internal Medicine and Pediatrics and are board-eligible for both at the conclusion of training. Graduates are eligible for fellowships in either or both fields. Many graduates pursue fellowship training. A small absolute number of graduates apply for dual training in adult and pediatric subspecialties, but those that do bring direct, in-depth clinical experience across the lifespan, and familiarity with care in both pediatric and adult settings. As such, they contribute unique perspectives and capabilities to their fellowship and future practice. This includes the ability to provide subspecialty care in settings with limited resources, where they are able to address needs without age restrictions, and in the transition of subspecialty care for emerging adults with childhood-onset conditions. Due to the small number of applicants pursuing joint adult and pediatric fellowships, many fellowship directors may have limited experience with dual fellowships but may want to create opportunities for these unique trainees. This summary was developed jointly by residents, fellows, MedPeds program directors, and fellowship directors in Pediatrics and Internal Medicine subspecialties, and approved by their respective leadership councils to offer some key points on common questions, suggest additional resources, and share best practices, with a goal of facilitating this process for fellowship programs and residents alike.

RESUMEN

BACKGROUND: Antihypertensive drugs with favorable metabolic effects are advocated for first-line therapy in hypertensive patients with metabolic/cardiometabolic syndrome (MetS). We compared outcomes by race in hypertensive individuals with and without MetS treated with a thiazide-type diuretic (chlorthalidone), a calcium channel blocker (amlodipine besylate), an alpha-blocker (doxazosin mesylate), or an angiotensin-converting enzyme inhibitor (lisinopril). METHODS: A subgroup analysis of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT), a randomized, double-blind hypertension treatment trial of 42 418 participants. We defined MetS as hypertension plus at least 2 of the following: fasting serum glucose level of at least 100 mg/dL, body mass index (calculated as weight in kilograms divided by height in meters squared) of at least 30, fasting triglyceride levels of at least 150 mg/dL, and high-density lipoprotein cholesterol levels of less than 40 mg/dL in men or less than 50 mg/dL in women. RESULTS: Significantly higher rates of heart failure were consistent across all treatment comparisons in those with MetS. Relative risks (RRs) were 1.50 (95% confidence interval, 1.18-1.90), 1.49 (1.17-1.90), and 1.88 (1.42-2.47) in black participants and 1.25 (1.06-1.47), 1.20 (1.01-1.41), and 1.82 (1.51-2.19) in nonblack participants for amlodipine, lisinopril, and doxazosin comparisons with chlorthalidone, respectively. Higher rates for combined cardiovascular disease were observed with lisinopril-chlorthalidone (RRs, 1.24 [1.09-1.40] and 1.10 [1.02-1.19], respectively) and doxazosin-chlorthalidone comparisons (RRs, 1.37 [1.19-1.58] and 1.18 [1.08-1.30], respectively) in black and nonblack participants with MetS. Higher rates of stroke were seen in black participants only (RR, 1.37 [1.07-1.76] for the lisinopril-chlorthalidone comparison, and RR, 1.49 [1.09-2.03] for the doxazosin-chlorthalidone comparison). Black patients with MetS also had higher rates of end-stage renal disease (RR, 1.70 [1.13-2.55]) with lisinopril compared with chlorthalidone. CONCLUSIONS: The ALLHAT findings fail to support the preference for calcium channel blockers, alpha-blockers, or angiotensin-converting enzyme inhibitors compared with thiazide-type diuretics in patients with the MetS, despite their more favorable metabolic profiles. This was particularly true for black participants.

RESUMEN

BACKGROUND: High dietary sodium intake may induce a small, yet physiologically relevant rise in serum sodium concentration, which associates with increased systolic blood pressure. Cellular data suggest that this association is mediated by increased endothelial cell stiffness. We hypothesized that higher serum sodium levels were associated with greater arterial stiffness in participants in the Systolic Blood Pressure Intervention Trial (SPRINT). METHODS: Multivariable linear regression was used to examine the association between baseline serum sodium level and (i) pulse pressure (PP; n = 8,813; a surrogate measure of arterial stiffness) and (ii) carotid-femoral pulse wave velocity (CFPWV; n = 591 in an ancillary study to SPRINT). RESULTS: Baseline mean ± SD age was 68 ± 9 years and serum sodium level was 140 ± 2 mmol/L. In the PP analysis, higher serum sodium was associated with increased baseline PP in the fully adjusted model (tertile 3 [≥141 mmol] vs. tertile 2 [139-140 mmol]; ß = 0.87, 95% CI = 0.32 to 1.43). Results were similar in those with and without chronic kidney disease. In the ancillary study, higher baseline serum sodium was not associated with increased baseline CFPWV in the fully adjusted model (ß = 0.35, 95% CI = -0.14 to 0.84). CONCLUSIONS: Among adults at high risk for cardiovascular events but free from diabetes, higher serum sodium was independently associated with baseline arterial stiffness in SPRINT, as measured by PP, but not by CFPWV. These results suggest that high serum sodium may be a marker of risk for increased PP, a surrogate index of arterial stiffness.

RESUMEN

Background Blood pressure ( BP ) varies over time within individual patients and across different BP measurement techniques. The effect of different BP targets on concordance between BP measurements is unknown. The goals of this analysis are to evaluate concordance between (1) clinic and ambulatory BP , (2) clinic visit-to-visit variability and ambulatory BP variability, and (3) first and second ambulatory BP and to evaluate whether different clinic targets affect these relationships. Methods and Results The SPRINT (Systolic Blood Pressure Intervention Trial) ambulatory BP monitoring ancillary study obtained ambulatory BP readings in 897 participants at the 27-month follow-up visit and obtained a second reading in 203 participants 293±84 days afterward. There was considerable lack of agreement between clinic and daytime ambulatory systolic BP with wide limits of agreement in Bland-Altman plots of -21 to 34 mm Hg in the intensive-treatment group and -26 to 32 mm Hg in the standard-treatment group. Overall, there was poor agreement between clinic visit-to-visit variability and ambulatory BP variability with correlation coefficients for systolic and diastolic BP all <0.16. We observed a high correlation between first and second ambulatory BP ; however, the limits of agreement were wide in both the intensive group (-27 to 21 mm Hg) and the standard group (-23 to 20 mm Hg). Conclusions We found low concordance in BP and BP variability between clinic and ambulatory BP and second ambulatory BP . Results did not differ by treatment arm. These results reinforce the need for multiple BP measurements before clinical decision making.

RESUMEN

BACKGROUND AND OBJECTIVES: In people with type 2 diabetes, aggressive control of glycemia, BP, and lipids have resulted in conflicting short-term (<5 years) kidney outcomes. We aimed to determine the long-term kidney effects of these interventions. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The Action to Control Cardiovascular Risk in Diabetes (ACCORD) was a multifactorial intervention study in people with type 2 diabetes at high risk for cardiovascular disease (n=10,251), to examine the effects of intensive glycemic control (hemoglobin A1c <6.0% versus 7%-7.9%), BP control (systolic BP <120 mm Hg versus <140 mm Hg) or fenofibrate versus placebo added to simvastatin on cardiovascular events and death. The glycemia trial lasted 3.7 years and participants were followed for another 6.5 years in ACCORDION, the ACCORD Follow-On Study. The post hoc primary composite kidney outcome was defined as incident macroalbuminuria, creatinine doubling, need for dialysis, or death by any cause. Cox proportional hazards regression estimated the effect of each intervention on the composite outcome and individual components. In secondary outcome analyses, competing risk regression was used to account for the risk of death in incident kidney outcomes. Analyses were adjusted for sociodemographics, randomization groups, and clinical factors. RESULTS: There were 988 cases of incident macroalbuminuria, 954 with doubling of creatinine, 351 requiring dialysis, and 1905 deaths. Hazard ratios (HRs) for the composite outcome with intensive glycemic, BP control, and fenofibrate use compared with standard therapy were 0.92 (95% confidence interval [95% CI], 0.86 to 0.98), 1.16 (95% CI, 1.05 to 1.28), and 1.16 (95% CI, 1.06 to 1.27). Multivariable, secondary outcome analyses showed that in the glycemia trial, only macroalbuminuria was significantly decreased (HR, 0.68; 95% CI, 0.59 to 0.77). In the BP and lipid trials, only creatinine doubling was affected (HR, 1.64; 95% CI, 1.30 to 2.06 and HR, 2.00; 95% CI, 1.61 to 2.49, respectively). CONCLUSIONS: In people with type 2 diabetes at high risk for cardiovascular disease, intensive glycemic control may result in a long-term reduction in macroalbuminuria; however, intensive BP control and fenofibrates may increase the risk for adverse kidney events.

RESUMEN

Charcot's arthropathy is a rare complication of diabetes that can result in significant morbidity. It may have a similar presentation to cellulitis, which often delays its recognition. While the pathogenesis remains unclear, timely diagnosis and treatment can help prevent the deformities associated with the late stages. It is important for physicians to recognize this complication early and use a team approach that includes an experienced orthopedic surgeon and/or podiatrist. We present a case and review the presentation, diagnosis and treatment of Charcot's arthropathy.

RESUMEN

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma and comprises approximately 30% of all lymphomas. Patients typically present with a nonpainful mass in the neck, groin, or abdomen associated with constitutional symptoms. In this report, however, the authors describe a rare case of a 61-year-old woman with hyperprolactinemia, hypothyroidism, and acromegaly (elevation of insulin-like growth factor-1 [IGF-1]) with elevated growth hormone-releasing hormone (GHRH) in whom an MRI demonstrated diffuse enlargement of the pituitary gland. Despite medical treatment, the patient had persistent elevation of IGF-1. She underwent a transsphenoidal biopsy, which yielded a diagnosis of DLBCL with an activated B-cell immunophenotype with somatotroph hyperplasia. After stereo-tactic radiation therapy in combination with chemotherapy, she is currently in remission from her lymphoma and has normalized IGF-1 levels without medical therapy, 8 months after her histopathological diagnosis. This is the only reported case of its kind and displays the importance of a broad differential diagnosis, multidisciplinary evaluation, and critical intraoperative decision-making when treating atypical sellar lesions.

RESUMEN

BACKGROUND: Metabolic syndrome (MS) is a well-known risk factor for the development of cardiovascular (CV) disease; yet, controversy persists whether it adds incremental prognostic value in patients with established CV disease. OBJECTIVES: This study was performed to determine if MS is associated with worse CV outcomes in patients with established CV disease treated intensively with statins. METHODS: We performed a post hoc analysis of the Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes trial, in which patients with established CV disease and atherogenic dyslipidemia (n = 3414) were randomly assigned to receive extended release niacin or placebo during a mean 36-month follow-up, to assess whether the presence of MS or the number of MS components contributed to CV outcomes. RESULTS: The composite primary end point of CV events occurred in 15.1% of patients without MS vs 13.8%, 16.9%, and 16.8% of patients with MS in the subsets with 3, 4, and 5 MS components, respectively (corresponding adjusted hazard ratios 0.9, 1.1, and 1.1 relative to patients without MS), P = .55. Comparing subgroups with 3 vs 4 or 5 MS components, there was no significant difference in either the composite primary end point or secondary end points. Patients with diabetes mellitus had higher event rates, with or without the presence of MS. CONCLUSIONS: The presence of MS was not associated with worse CV outcomes in the AIM-HIGH population. The rate of CV events in statin-treated Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes patients with MS was not significantly influenced by the number of MS components.

RESUMEN

OBJECTIVE: To determine whether the effects of intensive (<120 mmHg) compared with standard (<140 mmHg) systolic blood pressure (SBP) treatment are different among those with prediabetes versus those with fasting normoglycemia at baseline in the Systolic Blood Pressure Intervention Trial (SPRINT). RESEARCH DESIGN AND METHODS: This was a post hoc analysis of SPRINT. SPRINT participants were categorized by prediabetes status, defined as baseline fasting serum glucose ≥100 mg/dL versus those with normoglycemia (fasting serum glucose <100 mg/dL). The primary outcome was a composite of myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure, or death from cardiovascular causes. Cox regression was used to calculate hazard ratios for study outcomes with intensive compared with standard SBP treatment among those with prediabetes and normoglycemia. RESULTS: Among 9,361 participants randomized (age 67.9 ± 9.4 years; 35.5% female), 3,898 and 5,425 had baseline prediabetes and normoglycemia, respectively. After a median follow-up of 3.26 years, the hazard ratio for the primary outcome was 0.69 (95% CI 0.53, 0.89) and 0.83 (95% CI 0.66, 1.03) among those with prediabetes and normoglycemia, respectively (P value for interaction 0.30). For all-cause mortality, the hazard ratio with intensive SBP treatment was 0.77 (95% CI 0.55, 1.06) for prediabetes and 0.71 (95% CI 0.54, 0.94) for normoglycemia (P value for interaction 0.74). Effects of intensive versus standard SBP treatment on prespecified renal outcomes and serious adverse events were similar for prediabetes and normoglycemia (all interaction P > 0.05). CONCLUSIONS: In SPRINT, the beneficial effects of intensive SBP treatment were similar among those with prediabetes and fasting normoglycemia.

RESUMEN

BACKGROUND: Optimal first-step antihypertensive drug therapy in type 2 diabetes mellitus (DM) or impaired fasting glucose levels (IFG) is uncertain. We wished to determine whether treatment with a calcium channel blocker or an angiotensin-converting enzyme inhibitor decreases clinical complications compared with treatment with a thiazide-type diuretic in DM, IFG, and normoglycemia (NG). METHODS: Active-controlled trial in 31 512 adults, 55 years or older, with hypertension and at least 1 other risk factor for coronary heart disease, stratified into DM (n = 13 101), IFG (n = 1399), and NG (n = 17 012) groups on the basis of national guidelines. Participants were randomly assigned to double-blind first-step treatment with chlorthalidone, 12.5 to 25 mg/d, amlodipine besylate, 2.5 to 10 mg/d, or lisinopril, 10 to 40 mg/d. We conducted an intention-to-treat analysis of fatal coronary heart disease or nonfatal myocardial infarction (primary outcome), total mortality, and other clinical complications. RESULTS: There was no significant difference in relative risk (RR) for the primary outcome in DM or NG participants assigned to amlodipine or lisinopril vs chlorthalidone or in IFG participants assigned to lisinopril vs chlorthalidone. A significantly higher RR (95% confidence interval) was noted for the primary outcome in IFG participants assigned to amlodipine vs chlorthalidone (1.73 [1.10-2.72]). Stroke was more common in NG participants assigned to lisinopril vs chlorthalidone (1.31 [1.10-1.57]). Heart failure was more common in DM and NG participants assigned to amlodipine (1.39 [1.22-1.59] and 1.30 [1.12-1.51], respectively) or lisinopril (1.15 [1.00-1.32] and 1.19 [1.02-1.39], respectively) vs chlorthalidone. CONCLUSION: Our results provide no evidence of superiority for treatment with calcium channel blockers or angiotensin-converting enzyme inhibitors compared with a thiazide-type diuretic during first-step antihypertensive therapy in DM, IFG, or NG.

RESUMEN

BACKGROUND: Pituitary manifestation of Wegener granulomatosis (WG) is extremely rare. When there is pituitary involvement, the granulomatous inflammatory lesions involving the pituitary gland may appear several months to years after the primary diagnosis. CASE DESCRIPTION: We present a case of a 32-year-old woman who presented with galactorrhea, amenorrhea, and elevated serum prolactin levels. Imaging demonstrated a sellar lesion with characteristics of a pituitary macroadenoma. Treatment with cabergoline was initiated, but the tumor continued to grow during a 6-month period. Subsequent surgical exploration revealed a chronic inflammatory lesion; the patient subsequently was diagnosed with WG based on laboratory evaluation and further systemic manifestations. She had a favorable clinical and radiologic response with immunosuppressive doses of glucocorticoids and rituximab. CONCLUSIONS: This case appears to be the first reported of a patient with unknown WG in whom the diagnosis was established after she presented with a sellar lesion mimicking a prolactin-secreting pituitary adenoma on initial presentation requiring surgical resection. The only endocrine abnormality discovered was moderate hyperprolactinemia. Sellar lesions with only moderate elevations in serum prolactin, particularly those that are refractory to medical management with a dopamine agonist, should prompt further investigation to confirm the diagnosis. WG should be part of the differential diagnosis of inflammatory lesions in the sella, the identification of which can facilitate early diagnosis and treatment of this systemic disease for optimal outcome.
