Serum total L-carnitine levels in non-obese women with polycystic ovary syndrome

BACKGROUND: Carnitine plays essential roles in energy production, oxidative stress and glucose metabolism. This study was planned to determine serum total l-carnitine levels in non-obese women with polycystic ovary syndrome (PCOS). METHODS: There were 27 non-obese women with PCOS and 30 healthy, age- and body mass index (BMI) matched controls were evaluated in this controlled clinical study. Serum lipid sub-fractions, fasting glucose, insulin and other hormones (gonadotrophins, androgens) and total l-carnitine levels were measured. Homeostasis model assessment (HOMA-IR) was used to estimate insulin resistance. RESULTS: The women with PCOS had significantly higher serum dehydroepiandrosterone sulfate, total testosterone, free androgen index (FAI), luteinizing hormone (LH), low-density lipoprotein (LDL) cholesterol, non-high density lipoprotein (HDL) cholesterol, fasting insulin levels and HOMA-IR measurement and LH/FSH ratios than healthy women. However, total l-carnitine and sex hormone-binding globulin (SHBG) levels were significantly lower in women with PCOS. l-Carnitine level was negatively correlated with FAI, but positively correlated with SHBG. Multiple regression analysis revealed that SHBG was a strong predictor of serum total l-carnitine level. CONCLUSIONS: Decreased total l-carnitine levels may be associated with hyperandrogenism and/or insulin resistance in non-obese women with PCOS. Long-term studies are needed to evaluate carnitine metabolism in PCOS, especially with regard to the molecular basis. © The Author 2008.

Serum fetuin-A levels, insulin resistance and oxidative stress in women with polycystic ovary syndrome

This study was designed to determine serum Fetuin-A levels and establish whether serum Fetuin-A level is related with insulin resistance, oxidative stress, ovarian hyperandrogenism and dyslipidemia in women with polycystic ovary syndrome (PCOS). Twenty-two patients with PCOS and twenty-one healthy control women were evaluated in this controlled clinical study. Serum Fetuin-A, lipid fractions, glucose, insulin, malondialdehyde (MDA), myeloperoxidase (MPO), glutathione (GSH), superoxide dismutase (SOD) and other hormone (gonadotropins, androgens) levels were measured. The estimate of insulin resistance was calculated by homeostasis model assessment (HOMA-R). The women with PCOS had significantly higher serum fasting glucose, insulin, luteinizing hormone (LH), MDA, Fetuin-A levels, and LH/follicle-stimulating hormone (FSH) ratio, free androgen index (FAI), HOMA-IR than healthy women. However, sex hormone-binding globulin (SHBG) and GSH levels were significantly lower in patients with PCOS compared with controls. Fetuin-A was positively correlated with insulin, HOMA-IR and FAI. Multiple regression analysis revealed that FAI was strong predictor of serum Fetuin-A level. Serum Fetuin-A level was related with insulin resistance and ovarian hyperandrogenism in women with PCOS. These results suggest that Fetuin-A may have a role in triggering the processes leading to insulin resistance and androgen excess in PCOS. © 2013 Informa UK Ltd

Polikistik over sendromlu kadınlarda dolaşımdaki Tip 1 kolaj en C-Terminal propeptid düzeyleri

Objective: Collagen type I is abundant in the outer layers of capsular stroma and theca exter-na in the ovary. C-terminal propeptide of Type I collagen (CICP) is the measurable form of type I procol-lagen in serum. Circulating CICP levels are indicative of collagen production. This study was designed to determine the serum levels of CICP and tissue inhibitor of metalloproteinase-1 (TIMP-1) levels in women with Polycystic Ovary Syndrome (PCOS). Material and Methods: This study included twenty-five women with PCOS in the study group and twenty healthy women in the control group. Serum lipid sub-fracti-ons, fasting glucose and insulin, hormone (gonadotropins, androgens), CICP and TIMP-1 levels were me-asured. Homeostasis model assessment (HOMA-IR) was used to estimate insulin resistance. Results: Serum luteinizing hormone (LH) and fasting insulin levels, LH/follicule stimulating hormone (FSH) ratio, free an-drogen index (FAI) and HOMA-IR values were higher in patients with PCOS compared with healthy wo-men. A significant increase in CICP level was observed in subjects with PCOS, and TIMP-1 level was found to be significantly decreased. HOMA-IR value was positively correlated with CICP level, but inver-sely with TIMP-1 level. The best cut-off values for CICP and TIMP-1 were >49.94 ng/mL (sensitivity 92.6% and specificity 65%) and <275.99ng/ml (sensitivity 92.6% and specificity 40%) respectively. Con-clusion: Elevated circulating CICP levels may be associated with thickened tunica albuginea in women with PCOS. However, the exact role of CICP in the pathogenesis of the disease remains to be elucida-ted. © 2012 by Türkiye Klinikleri

Does apical prolapse in addition to early stage anterior prolapse have any effect on lower urinary tract symptoms?

OBJECTIVE: To investigate whether apical prolapse in addition to early-stage anterior prolapse has any effect on lower urinary tract symptoms (LUTS). METHODS: Patients with early-stage pelvic organ prolapse (POP) were retrospectively analyzed at the urogynecology unit of a tertiary referral center. Cases with posterior POP were excluded, and the remaining women were distributed across four main groups: (1) no determinable anterior and/or apical POP (control); (2) isolated anterior POP; (3) anterior + apical POP; and (4) isolated apical POP. Each LUTS symptom in these groups was recorded. Women with isolated anterior POP and women with anterior + apical POP were then compared to define the additional effects of apical prolapse on LUTS. In order to asses; symptoms of urgency, urinary incontinence, stress urinary incontinence, frequency, abnormal emptying, hesitancy, interrupted stream, nocturia, post-micturition dribble, and dysuria were noted and Incontinence Impact Questionnaire (IIQ-7), and domains of Urinary Distress Inventory (UDI-6) were compared between the groups. RESULTS: Of the 225 patients, 66 were excluded from the analysis due to accompanying posterior compartment defect. There was no statistically significant difference for age, systemic disease history, or smoking status between the groups (p > 0.05). However, history of traumatic vaginal delivery was significantly lower in the control group than in the other groups (p = 0.039). The prevalence of hesitancy and interrupted stream were found to be significantly higher in the anterior + apical POP group than in the isolated POP group (p<0.05). Obstructive subscale of the Urinary Distress Inventory was higher both in the isolated anterior POP and anterior + apical POP groups than the control group (p<0.05). CONCLUSION: The current study demonstrates that even minimal loss of apical support accompanying anterior prolapse exacerbates LUTS
