The relationship among androgens, insulin resistance and ghrelin polymorphisms in post-adolescent male patients with severe acne vulgaris.

INTRODUCTION: Ghrelin has anti-inflammatory and immunomodulatory activities. Data about the role of ghrelin and ghrelin polymorphisms in the development of acne vulgaris in post-adolescent male patients are limited. AIM: To evaluate the role of serum androgens, insulin resistance, ghrelin and ghrelin polymorphisms in severe acne vulgaris. MATERIAL AND METHODS: Thirty-five post-adolescent male patients with a mean age of 28.0 ±5.4 years and 33 age-and BMI-matched controls were enrolled. Serum androgens, lipids, insulin sensitivity parameters and ghrelin levels were determined. The PCR method was used for GHRL polymorphisms (rs27647, rs696217 and rs34911341 genotypes). RESULTS: Patients had similar anthropometric measures to controls, except a significantly higher WHR in patients (0.92 ±0.06 vs. 0.86 ±0.08, p < 0.05). Also, FPG, HOMA-IR values, lipid profile and serum androgen levels were similar. Interestingly, patients had significantly lower ghrelin levels than controls (4.5 ±5.8 vs. 101.2 ±86.5 pg/ml, p < 0.001). The frequencies of rs696217 and rs34911341 genotypes were similar whereas the distribution of rs27647 alleles was significantly different between the groups (p < 0.05). GA and GG genotypes of GHRL rs27647 polymorphism indicated an increased risk of developing acne vulgaris (OR = 11.156, 95% CI: 2.864-43.464, OR = 5.312, 95% CI: 1.269-22.244, respectively; p < 0.05). Patients with rs27647-AA polymorphism had significantly lower GAGS scores than other groups (AA genotype 6.7 ±14.1 vs. GA genotype 24.6 ±15.7 and GG genotype 19.4 ±17.9, p < 0.001). None of the polymorphisms had a significant effect on metabolic parameters, insulin sensitivity and serum ghrelin levels. CONCLUSIONS: Decreased ghrelin levels and GA and GG genotypes of GHRL gene rs27647 polymorphism may have a role in the pathogenesis of acne vulgaris.

Suppressed Adiponectin Levels and Increased Adiponectin Response to Oral Glucose Load in Lean Women with Severe Acne Normalizes after Isotretinoin Treatment.

BACKGROUND/AIM: Isotretinoin, the drug of choice for severe acne, might be associated with a decrease in insulin sensitivity. Adiponectin is an adipose tissue-derived protein that increases insulin sensitivity. In this study, we aimed to investigate adiponectin levels in postadolescent severe acne and the effect of isotretinoin on adiponectin levels. METHODS: Participants included 18 female patients with severe acne and 18 healthy women matched for age and body mass index (BMI). Acne patients completed a 6-month isotretinoin treatment. Anthropometric measurements, serum adiponectin, lipids, fasting glucose, fasting insulin, and homeostatic model assessment for insulin resistance (HOMA-IR) were determined, and a standard 2-h oral glucose tolerance test (OGTT) was performed in healthy women once and in patients with acne before and after treatment. RESULTS: At baseline, patients with acne had significantly lower serum adiponectin levels than controls. Isotretinoin treatment resulted in a significant increase in weight, BMI, and triglyceride and adiponectin levels. Glucose metabolism markers in patients with acne and controls were similar at baseline and did not change after treatment. Baseline OGTT in acne patients revealed an increased adiponectin response at 2 h, which was not present in healthy controls. Remarkably, this OGTT-induced adiponectin increment in acne patients was diminished after isotretinoin treatment. CONCLUSION: Adiponectin levels are differently regulated in women with severe acne and healthy controls in that circulating basal levels in patients are suppressed and show an increase in response to oral glucose load. Suppression of baseline adiponectin ameliorates after 6 months of isotretinoin treatment, reaching levels similar to those of healthy controls.

Fasting and post-prandial glucagon like peptide 1 and oral contraception in polycystic ovary syndrome.

OBJECTIVE: We aimed to investigate whether fasting and meal regulated glucagon like peptide 1 (GLP-1) secretion are altered in patients with polycystic ovary syndrome (PCOS) compared to healty women and whether oral contraceptive use influence GLP-1 secretion dynamics in the syndrome. DESIGN: Prospective observational study. PATIENTS: Fourteen lean normal glucose tolerant patients with PCOS and 11 age- and body mass index (BMI)-matched healthy women. MEASUREMENTS: Glucagon like peptide 1, glucose and insulin levels were measured during a standardized meal tolerance test and area under the curves (AUCs) were calculated. Whereas healthy controls were assessed at baseline, all tests were repeated in women with PCOS after treatment with ethinyl estradiol 30 µg/drospirenone 3 mg (EE/DRSP) for 3 months. RESULTS: Both fasting and post-meal levels of GLP-1 were significantly reduced in women with PCOS compared to controls (P = 0·022 and P = 0·028, respectively). AUC for GLP-1 was also lower in PCOS (P = 0·012). Glucose and insulin measurements did not show a significant change between the groups. In the PCOS group, GLP-1, glucose and insulin levels did not show any change after 3 months of EE/DRSP use. CONCLUSION: GLP-1 levels both at fasting and in response to a meal are blunted in lean women with PCOS compared to healthy women. Short term oral contraception do not alter GLP-1 secretion in PCOS. Disturbance in incretin secretion dynamics might contribute to the risk of impaired glucose tolerance and type 2 diabetes in PCOS.

Increased soluble selectins as a reflection of activated platelets and endothelium in Legg-Calve-Perthes disease.

BACKGROUND AND AIM: Legg-Calve-Perthes disease (LCPD) is still an enigma. Hemostatic abnormalities have been indicated in the pathogenesis. We had previously demonstrated enhanced tissue factor pathway inhibitor response, increased global fibrinolytic capacity, and an increase in thrombomodulin in patients with LCPD compared with healthy individuals. These studies emphasized the role of vascular endothelium in pathogenesis of the LCPD. P-selectin is expressed on activated platelets and endothelial cells, and E-selectin is expressed on activated endothelial cells. The aim of this study was to assess circulating E-selectin and P-selectin levels in LCPD patients, which might reflect an endothelium activation and/or injury. MATERIALS AND METHODS: The study included 85 pediatric patients. Group I consisted of 55 patients with LCPD and group II (control) consisted of 30 healthy children. Peripheral venous blood concentrations of E-selectin and P-selectin levels were measured with a commercially available assay. RESULTS: Mean age was 8.41±2.73 years in group I and 8.83±2.92 years in group II. Both E-selectin and P-selectin levels were higher in LCPD patients in comparison with the age-matched controls. E-selectin was 54.92±18.84 pg/mL in group I, 45.54±15.31 pg/mL in group II and P-selectin was 46.40±20.35 pg/mL in group I, 36.92±9.84 pg/mL in group II (P=0.022 and P=0.019, respectively). CONCLUSIONS: On the basis of our results, two important endothelium and platelet markers, E-selectin and P-selectin, are upregulated in LCPD. Our results suggested that activated platelets and possibly endothelial activation, as reflected by enhanced P-selectin/E-selectin kinetics, might contribute to the microvascular thrombosis and/or inflammation of LCPD.

Carotid artery intima-media thickness and erectile dysfunction in patients with metabolic syndrome.

BACKGROUND: Metabolic syndrome (MS) has become a pandemic in Turkey, as is the case globally. Increase in carotid artery intima-media thickness (CIMT) and erectile dysfunction (ED) may be evident before the clinical signs of cardiovascular disease appear. We aimed to investigate the prevalence of increased CIMT and ED as markers of atherosclerotic disease in patients with MS. MATERIAL AND METHODS: Thirty-two patients with MS and 29 healthy controls were included. Anthropometric and biochemical parameters, along with total testosterone (TT), high sensitive C-reactive protein (hs-CRP), were recorded. Carotid artery intima-media thickness was measured. Erectile dysfunction was assessed with International Index of Erectile Function. RESULTS: Patients with MS had higher BMI, fasting plasma glucose, post-prandial plasma glucose, insulin, HOMA-IR, total cholesterol, triglycerides, hs-CRP, and CIMT, whereas TT levels were lower (p<0.0001). The prevalence and severity of erectile dysfunction were higher in patients with MS (p<0.0001). Erectile dysfunction scores correlated inversely with CIMT. MS patients with ED were older and had higher CIMT compared to those without ED. Increase in age and HOMA and decrease in TT increased the risk of ED. When KIMT exceeding the 95th percentile of healthy controls was accepted as a risk factor for CVD, presence of ED was the only determinant for this increase. CONCLUSIONS: Erectile dysfunction was more prevalent and severe in patients with MS and correlated with subclinical endothelial dysfunction. Total testosterone deficiency was prominent among MS patients. Presence of ED points to an increased risk of cardiovascular disease when MS is present.

Burnout syndrome during residency in internal medicine and pediatrics in a country without working time directive.

PURPOSE: The purpose of this paper is to demonstrate burnout syndrome among internal medicine and pediatrics residents in a country that does not have the working time directive (WTD) and also to determine the risk factors and consequent impact on efficient functioning in clinical areas. DESIGN/METHODOLOGY/APPROACH: A 57-item questionnaire was given to internal medicine and pediatrics residents. Responses from 22 pediatrics and 33 internal medicine residents were evaluated. FINDINGS: Demographic findings, burnout scores, having hobbies, social activities and reading books unrelated to medicine were similar between the two groups. Six pediatrics residents (27.3 per cent) and 11 (33.3 per cent) internal medicine residents met the criteria for clinically significant burnout. Personal accomplishment scores and reading books unrelated to medicine were found to be related to burnout. ORIGINALITY/VALUE: Burnout is a syndrome characterized by depersonalization, emotional exhaustion and a low sense of personal accomplishment. It is important to document burnout in countries where WTDs are not implemented. Further studies might demonstrate burnout's effect on patient safety, service quality and physician's performance.

Serum resistin and high sensitive CRP levels in patients with subclinical hypothyroidism before and after L-thyroxine therapy.

BACKGROUND: Subclinical hypothyroidism (SH) is defined by increased thyrotropin (TSH) and normal free thyroxine (fT4) and free triiodothyronine (fT3) levels. Resistin is secreted from adipose tissue and is reported to be associated with insulin resistance and/or inflammation. High sensitive CRP (hs-CRP) is a reliable marker of inflammation. Data related to levels of resistin and hs-CRP in SH and the effect of L-thyroxine treatment on those is limited. We aimed to determine the levels of resistin and hs-CRP in women with SH, and potential effects of L-thyroxine therapy on those levels. MATERIAL AND METHODS: Thirty-six patients with SH and 27 age- and BMI-matched healthy control women were included. Waist circumference (Wc), waist-to-hip ratio (WHR), resting energy expenditure (REE), fat mass (FM) and lean mass (LM), TSH, free T4 (fT4), free T3 (fT3), total cholesterol (TC), triglycerides (TG), and HDL- and LDL-cholesterol were determined in all participants. Patients received L-thyroxine treatment for 6 months, after which all measurements were repeated. Resistin and hs-CRP levels were studied from frozen samples after the completion of the study. RESULTS: The 2 groups had similar values for Wc, WHR, FM, LM, TC, TG, HDL-C, LDL-C, resistin, and hs-CRP at the beginning. fT4 were higher, whereas TSH was lower in the control group. Resistin and hs-CRP levels did not change after treatment. hs-CRP correlated with BMI and FM before and after treatment. CONCLUSIONS: Our results suggest that achievement of euthyroid status by replacement therapy did not change resistin or hs-CRP levels in women with SH. hs-CRP correlated with parameters of obesity, which emphasizes the role of body weight in inflammation.

25-OH-Vitamin D and procalcitonin levels after correction of acute hyperglycemia.

BACKGROUND: Hyperglycemia is a common complication of diabetes melitis (DM) and in the absence of metabolic decompensation is a common finding in the Emergency Department (ED). We aimed to evaluate the 25 OH Vit D [25(OH)D] and procalcitonin (PCT) levels during hyperglycemia and after normalization of blood glucose. MATERIAL AND METHODS: The study included 88 patients over the age of 18 years who presented with acute hyperglycemia at the Hacettepe University Department of Emergency Medicine. Euglycemia was obtained within 6-12 hours and serum samples were taken from patients on admission and 6 hours after normalization of blood glucose. Along with plasma glucose, plasma 25(OH)D and PCT levels were measured using ELISA. RESULTS: There were 88 (45 males) patients, with a median age of 60.0±13.9 years. Serum 25(OH)D levels increased in all patients after normalization of blood glucose, and serum PCT levels decreased in the whole group. This decrease was independent of type of diabetes or presence of infection. CONCLUSIONS: We demonstrated an increase in 25(OH)D after normalization of blood glucose, and a decrease in PCT in patients with hyperglycemia. This effect was independent of the type of diabetes and presence of infection. Further studies are needed to evaluate the faster link between metabolic abnormalities, vitamin D, PCT, and inflammation.

Thyrotropinoma and multinodular goiter: A diagnostic challenge for hyperthyroidism.

Thyroid disorders are frequently encountered. The diagnosis is straightforward unless clinical or laboratory findings are inconclusive and/or perplexing. Hyperthyroidism due to a thyrotropin-secreting pituitary adenoma rarely occurs and symptoms due to thyroid hormone excess are subtle. The presentation of the disease becomes unusual when co-secretion of other hormones with thyrotropin or concomitant thyroid parenchymal pathology exist. We present the case of a 63-year-old female patient with thyrotropinoma co-secreting growth hormone and multinodular goiter. She developed hyperthyroidism first due to thyrotropinoma and later due to a toxic nodule. Herein, we discuss the diagnostic and therapeutic challenges of hyperthyroidism with atypical presentation.

Pigment epithelium-derived factor increases in type 2 diabetes after treatment with metformin.

OBJECTIVE: Pigment epithelium-derived factor (PEDF) has anti-angiogenic, immunomodulatory and anti-inflammatory properties. In addition to the significant role it plays in reducing diabetic complications, PEDF is now used in the treatment of certain cancers. It possibly plays a role in insulin resistance cases, too. However, whether metformin treatment has any significant effects on PEDF levels is not known. In this study, we investigated the regulation of PEDF in type 2 diabetes in relation to fat mass and insulin resistance before and after the use of metformin for treatment. DESIGN: Prospective cohort study. SUBJECTS: Thirty-six patients with newly diagnosed type 2 diabetes and 33 healthy individuals. MEASUREMENTS: Baseline weight, waist circumference (WC), fasting (FPG) and postprandial (PPPG) glucose, insulin, HbA1c, HOMA, PEDF and total/truncal fat mass were determined both in the diabetic and control subjects. Procedures were repeated in the diabetic group after a 6-month metformin treatment. RESULTS: Baseline FPG, PPPG, HbA1c, HOMA, weight, WC and truncal fat mass were higher in patients with diabetes whereas PEDF levels were found to be comparable with the controls. We completed the study with 31 of the 36 patients with diabetes we had selected for the study. We observed a decrease in the weight, WC, FPG, PPPG, HOMA, total and truncal fat mass of the patients while there was a significant rise in the PEDF levels (P = 0·002) after the metformin treatment. On the other hand, no significant correlation was observed between the change in PEDF levels and the clinical and laboratory findings. CONCLUSION: Our study is the first to identify a metformin-related increase in PEDF levels in diabetes. The increase observed in PEDF levels after the metformin treatment does not seem to be related to the changes in insulin resistance, fat mass or glycemic control. Hence, our results suggest that further investigation is necessary to determine the direct effects of metformin on PEDF gene and protein expression in vitro.

Depression, anxiety and cardiometabolic risk in polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with psychological and metabolic disturbances. The aim of this study was to determine whether depression, anxiety and reduced health-related quality of life (HRQOL) are more common in women with PCOS and associated with metabolic risk. METHODS: The study included 226 PCOS patients and 85 BMI-matched healthy control women. All participants completed standardized questionnaires assessing depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory) and both depression and anxiety (Hospital Anxiety and Depression Scale and General Health Questionnaire). Patients also completed a PCOS HRQOL questionnaire. Hirsutism scores, serum androgens and lipids were obtained. All subjects underwent a standard oral glucose tolerance test. RESULTS: 28.6% of PCOS women versus 4.7% of control women had clinical depression scores indicating an 8.1-fold increased risk of depression in PCOS (P < 0.001). Depression and anxiety scores were higher in PCOS women than controls (P < 0.01 for all subscales). Obese PCOS subjects had higher depression scores and rates than non-obese PCOS women (P < 0.05). Depression scores were significantly correlated with insulin resistance and lipid parameters and with the number of components comprising the metabolic syndrome. Menstrual and hirsutism problems were the most serious concerns followed by emotional problems on the HRQOL. CONCLUSIONS: Depression and anxiety are more common in patients with PCOS compared with healthy women. Depression in PCOS might be associated with obesity and metabolic abnormalities including insulin resistance and dyslipidemia.

The adhesion molecules of L-selectin and ICAM-1 in thrombocytosis and thrombocytopenia.

Thrombopoiesis is regulated by a variety of cytokines. Intracellular adhesion molecules are inducible cell-surface glycoproteins that belong to the immunoglobulin superfamily. Cytokines, endothelium and adhesive molecules represent the point of crosstalk in normal and pathological hematopoiesis. With the hypothesis that circulating intracellular adhesion molecule-1 (ICAM-1) and lymhocyte adhesion molecule-1 (L-selectin) concentrations could be changed based on pathological thrombopoiesis resulting in quantitative platelet disorders, we evaluated ICAM-1 and L-selectin levels in patients with thrombocytosis, thrombocytopenia and healthy controls. The L-selectin levels were found to be significantly higher in the thrombocytopenia group compared to the control group. ICAM-1 levels were found to be significantly higher in both thrombocytopenia and thrombocytosis groups compared to control group. Our study corroborates our original hypothesis implying the roles of adhesion molecules in the challenging status of pathological thrombopoiesis.

Predictive ability of fasting plasma glucose for a diabetic 2-h postload glucose value in oral glucose tolerance test: spectrum effect.

The performance of diagnostic tests may vary according to patient characteristics. The aim of this study is to find out the factors, if any, that may affect the performance of fasting plasma glucose (FPG) to predict a diabetic 2-h postload glucose level (> or =200 mg/dl) in oral glucose tolerance test (OGTT). One hundred ninety-six patients with known risk factors for diabetes mellitus to whom OGTT was applied were included. Factors that may have an effect on the performance of FPG in prediction of a diabetic value in OGTT were determined by using logistic regression and likelihood ratios (LRs). The cutoff of FPG predicting a 2-h postload glucose of > or =200 mg/dl was calculated by receiver operating characteristic curve as 110 mg/dl (sensitivity, 76.7%; specificity, 75.9%). Waist-to-hip ratio (WHR) and body mass index (BMI) influenced sensitivity, whereas age, family history, and presence of hyperlipidemia affected specificity of FPG. Significant factors for positive LR were age and hyperlipidemia, whereas sex, smoking, hyperlipidemia, physical inactivity, WHR, and BMI influenced negative LR. Fasting plasma glucose performance as a diagnostic test can be affected by many factors that are clearly stated as risk factors for diabetes mellitus. These data emphasize how the interpretation of a diagnostic test varies as the patient characteristics vary; the criteria that we confidently rely on may not be that reliable, changing between just two different patients.

A thyroidectomy case with a surprising pathologic result: three different birds in one nest.

Neoplasms of the thyroid include types that range from indolent, localized papillary carcinomas to lethal anaplastic disease. Hurthle cell neoplasm is a histopathologic subtype that signals poor prognosis. Herein, we present the case of a 72-year-old female patient with multinodular goiter who, although fine needle aspiration biopsy revealed a benign result, underwent thyroid surgery because of the diameter of the largest nodule. Histopathologically, the neoplasm was diagnosed as papillary thyroid microcarcinoma on one lobe and Hurthle cell neoplasm on the other, whereas the remainder of the thyroid showed a typical pattern of colloidal goiter, all of which are not commonly encountered in one patient. Although multinodular goiter is usually acknowledged as a sign of a benign process, its risk of malignancy is no less than that of a solitary thyroid nodule. The age of the patient, the duration of the disease, or the number of the nodules should not mislead the physician, nor affect the therapeutic approach.

Fasciola hepatica infection: clinical and computerized tomographic findings of ten patients.

BACKGROUND/AIMS: Fasciola hepatica is the cause of liver infection, fascioliasis. Although rare, it is still a problem even in developed countries. In this study, the clinical and computerized tomographic findings of 10 patients diagnosed with fascioliasis are summarized. METHODS: The medical records of the patients with fascioliasis were retrospectively examined. Clinical, laboratory findings and computerized tomographic results were recorded. RESULTS: Abdominal pain, fever, eosinophilia and abnormal liver function tests were the most commonly encountered symptoms and signs. One patient was human immunodeficiency virus -positive with active tuberculosis. Serologic test for fasciola hepatica was positive in all patients. Nodular masses without prominent enhancement, and branching low-attenuated tubular lesions were the most commonly seen tomographic findings and were supportive for the diagnosis. All except the HIV-positive patient received bithionol therapy; six patients responded well, two lost contact with the clinic and one patient who was unresponsive to bithionol therapy received triclabendazole. During follow-up of the six patients who responded, all the clinical and radiological findings regressed. CONCLUSION: In any patient with peripheral eosinophilia, abdominal pain and elevated liver enzymes, especially when CT reveals tubular and nodular hypodense lesions particularly in subcapsular area, F. hepatica infection should be considered. Either triclabendazole or bithionol can be used effectively for the treatment.

Acute Budd-Chiari syndrome resulting from a pyogenic liver abscess.

Budd-Chiari syndrome is a rare condition resulting from outflow obstruction of the liver. This syndrome due to a pyogenic abscess is rarely documented in the English literature. Here a male patient with acute Budd Chiari syndrome is presented. A 21-year-old male patient was admitted to the hospital because of severe right upper quadrant pain, jaundice, hepatomegaly and fever. The examination of liver by computerized tomography and ultrasound revealed a large lesion 120 x l00 mm in size located in the right lobe of liver, which was compressing the inferior vena cava, the right and middle hepatic veins. Twenty-three days after percutaneous catheter drainage and medical treatment, the patient was discharged with complete healing. Although many disorders including malignant diseases can cause Budd-Chiari Syndrome, a pyogenic liver abscess compressing the inferior vena cava, and hepatic veins leading to acute Budd-Chiari syndrome has been rarely reported in English medical literature. Patients presenting with abdominal pain, hepatomegaly, and ascites should be carefully evaluated from this point of view.

Posterior leukoencephalopathy and nephrotic syndrome: just a coincidence?

Posterior leukoencephalopathy syndrome (PLES) is an acute neurological disorder. The most plausible hypothesis for the pathophysiology of PLES is the loss of autoregulation and consequent vasogenic edema. PLES is mostly attributed to severe or sudden elevations of arterial blood pressure. A number of reports, however, describe patients with PLES without severe hypertension. This report presents two patients with nephrotic syndrome who developed PLES without customarily severe hypertension. Proteinuria, low levels of serum albumin, or generalized increase in capillary permeability in nephrotic syndrome can initiate PLES with moderately high arterial blood pressure levels. PLES is increasingly recognized by neurologists, but it should also be remembered by internists when confronted with patients with nephrotic syndrome who present with neurological symptoms, whether or not they have severe hypertension.

Superior vena cava thrombosis in chronic lead exposure--a case report.

Thrombosis is a rare cause of superior vena cava syndrome (SVCS). A 43-year-old male patient with SVCS due to thrombosis underwent investigation for the etiology of thrombus formation. He had been hospitalized several times because of lead intoxication in the past. Lead has a known thrombogenetic effect experimentally. This patient with superior vena cava thrombosis had thrombophilia that was probably due to lead intoxication. The etiologies of venous thrombosis and thrombogenetic effect of chronic lead exposure are discussed.

Insulin sensitivity, androgens and isotretinoin therapy in women with severe acne.

BACKGROUND: Androgens appear to play a role in the development of acne, and presence of acne is a potential marker of hyperandrogenism. OBJECTIVE: The authors evaluated androgens and insulin sensitivity markers before and after treatment with isotretinoin in women with post-adolescent severe acne who do not have hirsutism and/or ovulatory dysfunction. METHODS: Androgens, lipids, glucose and insulin levels were measured in 26 patients and 21 controls during oral glucose tolerance test. Homeostasis model assessment for insulin resistance, area under curve (AUC)glucose and AUCinsulin were calculated. Twenty patients completed a minimum of 6-month isotretinoin treatment. RESULTS: All studied parameters were similar in patients and controls at baseline. Isotretinoin therapy increased body mass index and triglyceride levels without any effect on androgens or insulin sensitivity. CONCLUSION: Severe acne itself is not associated with hyperandrogenemia and/or insulin resistance. Isotretinoin treatment does not alter serum androgens or insulin sensitivity, although it increases body weight and serum triglycerides.

Body composition in lean women with polycystic ovary syndrome: effect of ethinyl estradiol and drospirenone combination.

BACKGROUND: Limited data are available regarding the potential effects of oral contraceptives (OCs) on body fat distribution particularly in lean women with polycystic ovary syndrome (PCOS). In the current study, we aimed to evaluate the influence of ethinyl estradiol and drospirenone on body composition. STUDY DESIGN: Participants included 28 lean patients with PCOS and 28 age- and body mass index (BMI)-matched healthy women. The PCOS patients received ethinyl estradiol 30 mcg/drospirenone 3 mg for 6 months. Body composition parameters were assessed by bioelectrical impedance analysis. Serum androgens, lipids, insulin resistance and glucose metabolism measures were also determined. RESULTS: At baseline, the PCOS patients and controls had similar body composition, lipids, insulin resistance and glucose metabolism parameters. Total and trunk fat percentages were negatively correlated with sex hormone binding globulin and were positively correlated with homeostatic model assessment of insulin resistance and free androgen index in the PCOS group.. After 6 months of treatment in the PCOS patients, total fat percentage increased from 24.5%±7.1% to 26.0%±6.1% (p=.035) and trunk fat percentage increased from 20.2%±8.9% to 22.2%±7.1% (p=.014), although weight, BMI and waist to hip ratio (WHR) remained unchanged. CONCLUSION: Lean women with PCOS have similar body composition compared to healthy women. OC therapy for 6 months in PCOS patients results in an increased total and trunk fat percentage despite no change in clinical anthropometric measures including weight, BMI and WHR.
