THE EFFECTS OF PERIOPERATIVE DEXAMETHASONE ON GLYCEMIC CONTROL AND POSTOPERATIVE OUTCOMES.

Objective: Perioperative glucocorticoids are commonly given to reduce pain and nausea in patients undergoing surgery. However, the glycemic effects of steroids and the potential effects on morbidity and mortality have not been systematically evaluated. This study investigated the association between perioperative dexamethasone and postoperative blood glucose, hospital length of stay (LOS), readmission rates, and 90-day survival. Methods: Data from 4,800 consecutive orthopedic surgery patients who underwent surgery between 2000 and 2016 within a single health system were analyzed retrospectively. Results: Patients with and without diabetes mellitus (DM) who were given a single dose of dexamethasone had higher rates of hyperglycemia during the first 24 hours after surgery as compared to those who did not receive dexamethasone (hazard ratio [HR] was 1.81, and 95% confidence interval [CI] was [1.46, 2.24] for the DM cohort; HR 2.34, 95% CI [1.66, 3.29] for the nonDM cohort). LOS was nearly 1 day shorter in patients who received dexamethasone (geometric mean ratio [GMR] 0.79, 95% CI [0.75, 0.83] for patients with DM; GMR 0.75, 95% CI [0.72, 0.79] for patients without DM), and there was no difference in 90-day readmission rates. In patients without DM, dexamethasone was associated with a higher 90-day overall survival (99.07% versus 96.90%; P = .004). Conclusion: In patients with and without DM who undergo orthopedic surgery, perioperative dexamethasone was associated with a transiently higher risk of hyperglycemia. However, dexamethasone treatment was associated with a shorter LOS in patients with and without DM, and a higher overall 90-day survival rate in patients without DM, compared to patients who did not receive dexamethasone.

Development and Implementation of a Perioperative Blood Glucose Monitoring Protocol for Patients Undergoing Spinal Surgery.

PURPOSE: Stress-induced hyperglycemia during the perioperative period is associated with adverse outcomes after spinal surgery, which increases both patient-related burden and hospital costs. This quality improvement project describes the development and implementation of a perioperative blood glucose monitoring protocol for patients undergoing spinal surgery. DESIGN: An evidence-based perioperative blood glucose monitoring protocol was developed by a multidisciplinary committee of specialists in endocrinology and anesthesiology with utilization of the American Diabetes Association diabetes screening criteria. METHODS: The protocol was implemented in the perioperative areas of a regional hospital in the Southeastern United States. The project sample included patients with and without a prior diagnosis of diabetes who met protocol inclusion criteria during a 3-month implementation period. FINDINGS: Preoperative glycated hemoglobin (HbA1c) testing identified more than 54% of previously undiagnosed patients with levels consistent with either prediabetes or diabetes according to the American Diabetes Association criteria for diagnosis. Patients with diabetes and those without diabetes experienced a perioperative increase in blood glucose with levels remaining elevated above preoperative baseline through postoperative day 1. CONCLUSIONS: A perioperative blood glucose monitoring protocol enables preoperative identification of patients with undiagnosed prediabetes and diabetes, allowing for optimization before elective surgery and establishment of appropriate postoperative follow-up care. In addition, a blood glucose monitoring protocol increases the detection of perioperative hyperglycemia and may lead to a reduction in postoperative complications after spinal surgery.

DIFFERENCES IN ACHIEVING HBA1C GOALS AMONG PATIENTS SEEN BY ENDOCRINOLOGISTS AND PRIMARY CARE PROVIDERS.

Objective: This study evaluated whether there is a difference in the proportion of patients with type 2 diabetes who achieve a hemoglobin A1c (HbA1c) <7% within one year following treatment by an endocrinologist or primary care physician (PCP). Methods: We conducted a retrospective, propensity-matched study of patients with type 2 diabetes that were not optimally controlled and seen within our health system from 2007-2016. We assessed differences in short term health outcomes for patients following an endocrinologist visit compared to a PCP visit. Results: Patients seen by endocrinologists obtained HbA1c control at a faster rate (hazard ratio = 1.226; 95% confidence interval = 1.01 to 1.488) than those seen by a PCP. Furthermore, 34.5% and 29.5% of those treated by endocrinologists and PCPs, respectively, obtained HbA1c control by one year. Endocrinologists were more likely to prescribe a new medication class within 90 days than PCPs (14.1% versus 10.3%, respectively, P = .043). There was no difference in the risk of hospitalization between groups; 24.4% and 24.1% of those treated by endocrinologists and PCPs, respectively, were hospitalized within one year. Conclusion: Patients treated by endocrinology specialists were more likely to achieve a target HbA1c of <7% (53 mmol/mol) than those treated by PCPs in our health-care system. The performance difference may be partially explained by a higher rate of adding new classes of diabetes medications to the patient's pharmacologic regimens within 90 days by endocrinologists compared with PCPs. The long-term impact of these differences is unknown but has the potential to have an unfavorable impact on the health of the population.

Assessing the Impact of an Order Panel Utilizing Weight-Based Insulin and Standardized Monitoring of Blood Glucose for Patients With Hyperkalemia.

Intravenous insulin with glucose is used in urgent treatment for hyperkalemia but has a significant risk of hypoglycemia. The authors developed an order panel within the electronic health record system that utilizes weight-based insulin dosing and standardized blood glucose monitoring to reduce hypoglycemia. As initial evaluation of this protocol, the authors retrospectively compared potassium and blood glucose lowering in patients treated with the weight-based (0.1 units/kg) insulin order panel (n = 195) with those given insulin based on provider judgment (n = 69). Serum potassium lowering did not differ between groups and there was no relationship between dose of insulin and amount of potassium lowering. There was a difference in hypoglycemia rates between groups ( P = .049), with fewer severe hypoglycemic events in the panel (2.56%) than in the non-panel group (10.14%). These data suggest weight-based insulin dosing is equally effective for lowering serum potassium and may lower risk of severe hypoglycemia.

Effect of A1C and Glucose on Postoperative Mortality in Noncardiac and Cardiac Surgeries.

OBJECTIVE: Hemoglobin A1c (A1C) is used in assessment of patients for elective surgeries because hyperglycemia increases risk of adverse events. However, the interplay of A1C, glucose, and surgical outcomes remains unclarified, with often only two of these three factors considered simultaneously. We assessed the association of preoperative A1C with perioperative glucose control and their relationship with 30-day mortality. RESEARCH DESIGN AND METHODS: Retrospective analysis on 431,480 surgeries within the Duke University Health System determined the association of preoperative A1C with perioperative glucose (averaged over the first 3 postoperative days) and 30-day mortality among 6,684 noncardiac and 6,393 cardiac surgeries with A1C and glucose measurements. A generalized additive model was used, enabling nonlinear relationships. RESULTS: A1C and glucose were strongly associated. Glucose and mortality were positively associated for noncardiac cases: 1.0% mortality at mean glucose of 100 mg/dL and 1.6% at mean glucose of 200 mg/dL. For cardiac procedures, there was a striking U-shaped relationship between glucose and mortality, ranging from 4.5% at 100 mg/dL to a nadir of 1.5% at 140 mg/dL and rising again to 6.9% at 200 mg/dL. A1C and 30-day mortality were not associated when controlling for glucose in noncardiac or cardiac procedures. CONCLUSIONS: Although A1C is positively associated with perioperative glucose, it is not associated with increased 30-day mortality after controlling for glucose. Perioperative glucose predicts 30-day mortality, linearly in noncardiac and nonlinearly in cardiac procedures. This confirms that perioperative glucose control is related to surgical outcomes but that A1C, reflecting antecedent glycemia, is a less useful predictor.

Effects of exercise training alone vs a combined exercise and nutritional lifestyle intervention on glucose homeostasis in prediabetic individuals: a randomised controlled trial.

AIMS/HYPOTHESIS: Although the Diabetes Prevention Program (DPP) established lifestyle changes (diet, exercise and weight loss) as the 'gold standard' preventive therapy for diabetes, the relative contribution of exercise alone to the overall utility of the combined diet and exercise effect of DPP is unknown; furthermore, the optimal intensity of exercise for preventing progression to diabetes remains very controversial. To establish clinical efficacy, we undertook a study (2009 to 2013) to determine: how much of the effect on measures of glucose homeostasis of a 6 month programme modelled after the first 6 months of the DPP is due to exercise alone; whether moderate- or vigorous-intensity exercise is better for improving glucose homeostasis; and to what extent amount of exercise is a contributor to improving glucose control. The primary outcome was improvement in fasting plasma glucose, with improvement in plasma glucose AUC response to an OGTT as the major secondary outcome. METHODS: The trial was a parallel clinical trial. Sedentary, non-smokers who were 45-75 year old adults (n = 237) with elevated fasting glucose (5.28-6.94 mmol/l) but without cardiovascular disease, uncontrolled hypertension, or diabetes, from the Durham area, were studied at Duke University. They were randomised into one of four 6 month interventions: (1) low amount (42 kJ kg body weight(-1) week(-1) [KKW])/moderate intensity: equivalent of expending 42 KKW (e.g. walking ∼16 km [8.6 miles] per week) with moderate-intensity (50% [Formula: see text]) exercise; (2) high amount (67 KKW)/moderate intensity: equivalent of expending 67 KKW (∼22.3 km [13.8 miles] per week) with moderate-intensity exercise; (3) high amount (67 KKW)/vigorous intensity: equivalent to group 2, but with vigorous-intensity exercise (75% [Formula: see text]); and (4) diet + 42 KKW moderate intensity: same as group 1 but with diet and weight loss (7%) to mimic the first 6 months of the DPP. Computer-generated randomisation lists were provided by our statistician (G. P. Samsa). The randomisation list was maintained by L. H. Willis and C. A. Slentz with no knowledge of or input into the scheduling, whereas all scheduling was done by L. A. Bateman, with no knowledge of the randomisation list. Subjects were automatically assigned to the next group listed on the randomisation sheet (with no ability to manipulate the list order) on the day that they came in for the OGTT, by L. H. Willis. All plasma analysis was done blinded by the individuals doing the measurements (i.e. lipids, glucose, insulin). Subjects and research staff (other than individuals analysing the blood) were not blinded to the group assignments. RESULTS: Number randomised, completers and number analysed with complete OGTT data for each group were: low-amount/moderate-intensity (61, 43, 35); high-amount/moderate-intensity (61, 44, 40); high-amount/vigorous-intensity (61, 43, 38); diet/exercise (54, 45, 37), respectively. Only the diet and exercise group experienced a decrease in fasting glucose (p < 0.001). The means and 95% CIs for changes in fasting glucose (mmol/l) for each group were: high-amount/moderate-intensity -0.07 (-0.20, 0.06); high-amount/vigorous 0.06 (-0.07, 0.19); low-amount/moderate 0.05 (-0.05, 0.15); and diet/exercise -0.32 (-0.46, -0.18). The effects sizes for each group (in the same order) were: 0.17, 0.15, 0.18 and 0.71, respecively. For glucose tolerance (glucose AUC of OGTT), similar improvements were observed for the diet and exercise (8.2% improvement, effect size 0.73) and the 67 KKW moderate-intensity exercise (6.4% improvement, effect size 0.60) groups; moderate-intensity exercise was significantly more effective than the same amount of vigorous-intensity exercise (p < 0.0207). The equivalent amount of vigorous-intensity exercise alone did not significantly improve glucose tolerance (1.2% improvement, effect size 0.21). Changes in insulin AUC, fasting plasma glucose and insulin did not differ among the exercise groups and were numerically inferior to the diet and exercise group. CONCLUSIONS/INTERPRETATION: In the present clinical efficacy trial we found that a high amount of moderate-intensity exercise alone was very effective at improving oral glucose tolerance despite a relatively modest 2 kg change in body fat mass. These data, combined with numerous published observations of the strong independent relation between postprandial glucose concentrations and prediction of future diabetes, suggest that walking ∼18.2 km (22.3 km prescribed with 81.6% adherence in the 67 KKW moderate-intensity group) per week may be nearly as effective as a more intensive multicomponent approach involving diet, exercise and weight loss for preventing the progression to diabetes in prediabetic individuals. These findings have important implications for the choice of clinical intervention to prevent progression to type 2 diabetes for those at high risk. TRIAL REGISTRATION: ClinicalTrials.gov NCT00962962 FUNDING: The study was funded by National Institutes for Health National Institute of Diabetes and Digestive and Kidney Diseases (NIH-NDDK) (R01DK081559).

Technosphere insulin: inhaled prandial insulin.

INTRODUCTION: Insulin therapy is a mainstay for treatment of diabetes mellitus; however, many barriers to insulin exist. Insulin human inhalation powder (technosphere insulin) is a new FDA-approved alternative to subcutaneous bolus insulin. AREAS COVERED: This is an overview of technosphere insulin (TI). Pharmacokinetics, clinical efficacy, safety and tolerability are discussed. EXPERT OPINION: TI is more quickly absorbed than subcutaneous insulin therapies and has a shorter duration of action. It appears to be noninferior compared with subcutaneous insulin regimens, and is associated with less hypoglycemia. Thus, it may serve as an alternative insulin agent in patients reluctant to administer multiple subcutaneous injections of insulin daily or in patients who experience late postprandial hypoglycemia with subcutaneous insulin. Cough is the most common side effect, but tends to be mild and transient. A small decrease in the forced expiratory volume has been demonstrated, but does not appear to progress and is reversible. Patients should have periodic pulmonary function tests. TI is contraindicated in patients with chronic lung disease. The long-term risk of lung cancer is being monitored but at this point does not appear to be higher than the expected incidence of lung cancer in this population.

Patient Self-Management of Diabetes Care in the Inpatient Setting: Pro.

Patients should be allowed to manage their diabetes in the hospital. Diabetes mellitus is a common and sometimes difficult to control medical issue in hospitalized patients. Oftentimes patients who have been controlling their diabetes well as an outpatient are not allowed to continue this management on the inpatient setting, which can lead to hypo- and hyperglycemia. Involving the patient in his or her diabetes care, including self-management in select patients, may provide a safe and effective way of improving glycemic control and patient satisfaction. This may particularly benefit the dosing and coordination of meal-time.

Managing hyperglycemia and diabetes in patients receiving enteral feedings: A health system approach.

Evidence of poor outcomes in hospitalized patients with hyperglycemia has led to new and revised guidelines for inpatient management of diabetes. As providers become more aware of the need for better blood glucose control, they are finding limited guidance in the management of patients receiving enteral nutrition. To address the lack of guidelines in this population, Duke University Health System has developed a consistent practice for managing such patients. Here, we present our practice strategies for insulin use in patients receiving enteral nutrition. Essential factors include assessing the patients' history of diabetes, hyperglycemia, or hypoglycemia and timing and type of feedings. Insulin practices are then designed to address these issues keeping in mind patient safety in the event of abrupt cessation of nutrition. The outcome of the process is a consistent and safe method for glucose control with enteral nutrition.

Review of nonalcoholic fatty liver disease in women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women. Women with PCOS frequently have metabolic complications including insulin resistance (IR), early diabetes, hypertension and dyslipidemia. Recent studies have demonstrated an association between PCOS and another metabolic complication: nonalcoholic fatty liver disease (NAFLD). NAFLD occurs as a result of abnormal lipid handling by the liver, which sensitizes the liver to injury and inflammation. It can progress to nonalcoholic steatohepatitis (NASH), which is characterized by hepatocyte injury and apoptosis. With time and further inflammation, NASH can progress to cirrhosis. Thus, given the young age at which NAFLD may occur in PCOS, these women may be at significant risk for progressive hepatic injury over the course of their lives. Many potential links between PCOS and NAFLD have been proposed, most notably IR and hyperandrogenemia. Further studies are needed to clarify the association between PCOS and NAFLD. In the interim, clinicians should be aware of this connection and consider screening for NAFLD in PCOS patients who have other metabolic risk factors. The optimal method of screening is unknown. However, measuring alanine aminotransferase and/or obtaining ultrasound on high-risk patients can be considered. First line treatment consists of lifestyle interventions and weight loss, with possible pharmacologic interventions in some cases.

Polycystic ovary syndrome: update on diagnosis and treatment.

Polycystic ovary syndrome is now a well-recognized condition affecting 6%-25% of reproductive-aged women, depending on the definition. Over the past 3 decades, research has launched it from relative medical obscurity to a condition increasingly recognized as common in internal medicine practices. It affects multiple systems, and requires a comprehensive perspective on health care for effective treatment. Metabolic derangements and associated complications include insulin resistance and diabetes, hyperlipidemia, hypertension, fatty liver, metabolic syndrome, and sleep apnea. Reproductive complications include oligo-/amenorrhea, sub-fertility, endometrial hyperplasia, and cancer. Associated psychosocial concerns include depression and disordered eating. Additionally, cosmetic issues include hirsutism, androgenic alopecia, and acne. This review organizes this multi-system approach around the mnemonic "MY PCOS" and discusses evaluation and treatment options for the reproductive, cosmetic, and metabolic complications of this condition.

Screening for glucose intolerance in polycystic ovary syndrome: hemoglobin A1C, fasting blood glucose or oral glucose tolerance test?

Polycystic ovary syndrome (PCOS) is a chronic condition with many reproductive, metabolic and psychological manifestations. Insulin resistance puts women with PCOS at an increased risk for developing impaired glucose tolerance (IGT) and diabetes (T2D). An oral glucose tolerance test is the preferred IGT/T2D screening test, since it is most sensitive for detecting early glucose abnormalities. The goals in detecting IGT in these women are to avoid progression to T2D, modify cardiovascular risk and prevent gestational diabetes. Periodic IGT/T2D rescreening is necessary, given their propensity for more rapid deterioration in glucose tolerance. Lifestyle intervention is first-line therapy for PCOS women with IGT. Metformin is an option if lifestyle intervention fails to have an impact, while bariatric surgery is reserved for a select set of morbidly obese patients.

Higher high-density lipoprotein cholesterol in African-American women with polycystic ovary syndrome compared with Caucasian counterparts.

CONTEXT: Studies have demonstrated lipid differences among African-Americans and Caucasians and between women with polycystic ovary syndrome (PCOS) and normally ovulating women. However, few studies have examined racial differences in lipoprotein levels in women with PCOS. OBJECTIVE: This study compared lipoprotein levels in African-American and Caucasian women with PCOS. DESIGN AND SETTING: We performed a retrospective chart review of 398 subjects seen as new patients for PCOS at the Duke University Medical Center Endocrinology Clinic in Durham, NC. PATIENTS: We identified 126 charts appropriate for review, based on a diagnosis of PCOS (using the 1990 National Institutes of Health criteria), a self-reported race of either Caucasian or African-American, and a body mass index (BMI) higher than 25. We excluded patients taking glucophage, oral contraceptives, or lipid-lowering medications. MAIN OUTCOME MEASURE: Age, BMI, total cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, random triglycerides (TG), and oral glucose tolerance test measurements were collected and included in the analysis. RESULTS: African-American women with PCOS had higher HDL cholesterol levels (52.6 vs. 47.5 mg/dl, P = 0.019), lower non-HDL cholesterol (134.1 vs. 154.6 mg/dl, P = 0.046), and lower TG levels (97.5 vs. 168.2 mg/dl, P < 0.001) than Caucasian women. These differences could not be attributed to age, BMI, or differences in insulin resistance as determined by homeostasis model assessment of insulin resistance. CONCLUSION: African-American women with PCOS appear to have a more favorable lipid profile than Caucasian women with PCOS having higher HDL cholesterol, lower non-HDL cholesterol, and lower TG when BMI and insulin resistance are equal.

Effects of exercise on lipoprotein particles in women with polycystic ovary syndrome.

PURPOSE: Women with polycystic ovary syndrome (PCOS) commonly have insulin resistance. Insulin resistance is associated with marked abnormalities of lipoprotein size and subclass particle concentration. The purpose of this study was to examine the effects of a moderate-intensity exercise program without weight loss on lipoprotein profiles in women with PCOS. METHODS: Thirty-seven sedentary PCOS women were randomized to either an 8- to 12-wk ramp-up followed by a 12-wk moderate-intensity exercise program (16-24 wk total, approximately 228 min x wk at 40-60% peak V x O2, n = 21) or control (no change in lifestyle, n = 16). PCOS was defined as or=8). Fasting lipoprotein profiles were obtained before and after the intervention. Nuclear magnetic resonance spectroscopy was used to quantify the following: average particle size, total and subclass concentrations of HDL, LDL, and VLDL particles, and calculated HDL cholesterol, triglycerides, and VLDL triglycerides. Wilcoxon exact rank sums tests were used to compare changes in these parameters in the exercise group relative to controls. RESULTS: Twenty women (8 exercisers, 12 controls) completed the study. Comparing exercisers to controls, significant changes were seen in concentrations of the following lipoprotein parameters that are associated with decreased insulin resistance: decreased large VLDL (P = 0.007), calculated triglycerides (P = 0.003), VLDL triglycerides (P = 0.003), and medium/small HDL (P = 0.031) and increased large HDL (P = 0.002) and average HDL size (P = 0.001). CONCLUSIONS: In this trial, moderate-intensity exercise without significant weight loss improved several components of the lipoprotein profiles of women with PCOS. These findings support the beneficial role of moderate exercise in this high-risk population.

Polycystic ovary syndrome: diagnosis and treatment.

Polycystic ovary syndrome affects 6%-7% of reproductive-aged women, making it the most common endocrine disorder in this population. It is characterized by chronic anovulation and hyperandrogenism. Affected women may present with reproductive manifestations such as irregular menses or infertility, or cutaneous manifestations, including hirsutism, acne, or male-pattern hair loss. Over the past decade, several serious metabolic complications also have been associated with polycystic ovary syndrome including type 2 diabetes mellitus, metabolic syndrome, sleep apnea, and possibly cardiovascular disease and nonalcoholic fatty liver disease. In addition to treating symptoms by regulating menstrual cycles and improving hyperandrogenism, it is imperative that clinicians recognize and treat metabolic complications. Lifestyle therapies are first-line treatment in women with polycystic ovary syndrome, particularly if they are overweight. Pharmacological therapies are also available and should be tailored on an individual basis. This article reviews the diagnosis, clinical manifestations, metabolic complications, and treatment of the syndrome. A table summarizing treatment recommendations is provided.

Nonalcoholic steatohepatitis and nonalcoholic Fatty liver disease in young women with polycystic ovary syndrome.

CONTEXT: Nonalcoholic fatty liver disease and polycystic ovary syndrome (PCOS) are both associated with insulin resistance. Thus, women with PCOS may have an increased prevalence of nonalcoholic fatty liver disease, including nonalcoholic steatohepatitis (NASH). OBJECTIVE: The objective of the study was to determine the prevalence and characteristics of NASH and abnormal aminotransferase activity in women with PCOS. DESIGN: The study is a retrospective chart review. SETTING: The setting is an academic endocrinology clinic. PATIENTS: Patients were 200 women with PCOS, defined as irregular menses and hyperandrogenism. MAIN OUTCOME MEASURES: Biopsy-documented NASH and aminotransferase levels were the main outcome measures. RESULTS: Fifteen percent (29 of 200) had aspartate aminotransferase and/or alanine aminotransferase more than 60 U/liter. Women with aminotransferase elevations had lower high-density lipoprotein (HDL) (41 vs. 50 mg/dl, P = 0.006), higher triglycerides (174 vs. 129 mg/dl, P = 0.024), and higher fasting insulin (21 vs. 12 microIU/ml, P = 0.036) compared with women with normal aminotransferases. Six women (mean age 29 yr) with persistent aminotransferase elevations underwent liver biopsy. All six had NASH with fibrosis. Compared with the 194 of 200 PCOS women who did not undergo biopsy, women with biopsy-documented NASH had lower HDL (median 34 vs. 50 mg/dl, P < 0.001), and higher triglycerides (245 vs. 132 mg/dl, P = 0.025), fasting insulin (26 vs. 13 microIU/ml, P = 0.038), aspartate aminotransferase (144 vs. 22 U/liter, P < 0.001), and alanine aminotransferase (143 vs. 28 U/liter, P < 0.001). CONCLUSION: Abnormal aminotransferase activity is common in women with PCOS. Low HDL, high triglycerides, and high fasting insulin were associated with abnormal aminotransferase activity. Some women already had evidence of NASH with fibrosis. Further studies are needed to evaluate whether to screen PCOS women for liver disease at an earlier age than is currently recommended for the general population.

Polycystic ovary syndrome and severe nonalcoholic steatohepatitis: beneficial effect of modest weight loss and exercise on liver biopsy findings.

OBJECTIVE: To report a case of biopsy-documented nonalcoholic steatohepatitis (NASH), which improved appreciably through moderate exercise and weight loss in a young woman with polycystic ovary syndrome (PCOS) and insulin resistance. METHODS: We present a detailed case report, including laboratory and pathologic findings. In addition, we review the recent literature regarding the association of insulin resistance with NASH and PCOS. RESULTS: A 24-year-old woman was referred to the Duke Gastroenterology Clinic for evaluation of long-term high serum aminotransferase levels. She also reported a history of chronically irregular menses, infertility, and hirsutism and was diagnosed with PCOS. Subsequent glucose tolerance testing suggested the presence of insulin resistance. Liver biopsy findings were consistent with severe nonalcoholic steatohepatitis. Under the supervision of her physician and an exercise physiologist, the patient initiated a diet and exercise program that resulted in an 11.5% weight loss during approximately 8 months and yielded normalization of her aminotransferase levels. A repeat liver biopsy done 13 months after the initial biopsy revealed a substantial decrease in steatosis and a reduction in inflammation. CONCLUSION: Women with PCOS and insulin resistance have an increased risk of developing many of the consequences of the dysmetabolic syndrome, including type 2 diabetes, hypertension, and hyperlipidemia. This case report suggests that fatty liver and NASH may be other important diseases to identify in such women. It also demonstrates the improvement in this condition with moderate exercise and weight loss.
