Acute phase proteins: C-reactive protein and fibrinogen in young women with polycystic ovary syndrome.

Females with polycystic ovary syndrome (PCOS) are characterized by several metabolic abnormalities that favor the development of atherosclerosis. Atherosclerosis is possibly a chronic inflammatory process, and the markers of the inflammatory state, such as C-reactive protein (CRP) and fibrinogen may be useful to assess the global risk of developing cardiovascular diseases. These proteins might be helpful in finding females with subclinical atherosclerosis. The purpose of this study was to assess the serum CRP and fibrinogen concentrations in young females with PCOS and to clarify the possible correlations between their levels and selected anthropometric, metabolic and hormonal indices. Study assessed a group of 57 females with PCOS (mean age 28.2+/-6.4 years). That group was further divided into two subgroups: the first with body mass index (BMI)</=25 (21 females of mean age 27.4+/-7.0 years) and second with BMI>25 (36 females of mean age 28.6+/-6.0 years). In the control group there were 22 healthy females (mean age 31.6+/-8.5 years). That group was again divided into two subgroups: the first with BMI</=25 (10 females, mean age 30.2+/-8.4 years) and second with BMI>25 (12 females, mean age 31.7+/-8.7 years). Results demonstrated statistically significantly higher CRP concentration in females with PCOS compared to healthy individuals in both BMI subgroups. PCOS females showed also higher plasma insulin levels. There was, however, no statistically significant difference in fibrinogen concentrations. The hormonal profile of females with PCOS seems to influence the concentration of CRP and fibrinogen in different ways. This was evident in the positive correlation between plasma fibrinogen and androstenedione and in the lack of correlation between CRP and androgens and in the positive correlation between CRP and estradiol and the negative correlation between fibrinogen and estradiol. In conclusion, high CRP concentration in females with PCOS probably speaks for a higher risk for cardiovascular diseases.

Detection of colorectal lesions by using autofluorescence colonoscopy in acromegalics and their relation to serum growth hormone and insulin-like growth factor-1 levels.

OBJECTIVES: Acromegalics have an increased risk of colorectal neoplasm. The aim of this study was to establish the association between acromegaly and colorectal lesions. MATERIALS AND METHODS: The study included 51 patients with active acromegaly: 30 women and 21 men (average age 52.95 +/- 13.49 years). Growth hormone (GH), insulin-like growth factor I (IGF-I), prolactin (PRL), thyreothropin (TSH), thyroxine (FT4) were measured in the serum when patients were hospitalized for their first diagnosis of acromegaly, before starting the treatment. All patients underwent colonoscopy--in the first phase conventional in white light; in the second phase fluorescence colonoscopy. Autofluorescence of colonic mucosa was assessed by illumination with monochromatic light. Green fluorescence is characteristic for normal colonic mucose, whereas red fluorescence occur in pathological lesions. Material to histopathological examination was taken from every pathological colorectal lesion. RESULTS: Using conventional colonoscopy we detected colonic polyps in 21 acromegalic patients (41.17%). Polyps with red fluorescence were found in 7 (13.7%) acromegalics and with green fluorescence in 16 (31.37%) cases of these patients. Histological diagnoses of colorectal lesions are adenoma, hyperplastic and inflammatic polyps. The number of colorectal polyps was dependent on IGF-I, fT4 and sex. CONCLUSIONS: Acromegaly is associated with high prevalence of colorectal pathology, mainly hyperplastic polyp and adenoma. There is a relationship between number of colorectal polyps and serum IGF-I levels in acromegaly. Adenomas and hyperplastic polyps were associated with higher levels of IGF-I.

Plasma ghrelin concentrations in patients with polycystic ovary syndrome before and after 6months therapy: correlation with androgen levels.

OBJECTIVE: Ghrelin is a natural ligand of the growth hormone secretagogue receptor and has been shown to be a potent stimulant of GH secretion. It has also orexigenic effects and regulates energy homeostasis. Recent studies claim that ghrelin influences the androgen level and probably takes part in PCOS pathomechanism. The aim of the study was an assessment of ghrelin level in plasma in women with PCOS before and after the treatment and ghrelin's influence on androgen level change. MATERIAL AND METHODS: The study included 25 women with the diagnosed PCOS (mean age 25.3+/-4.05 yr). The tests were done twice: before the treatment and after 6-month therapy with Diane 35 (cyproterone acetate 2 mg with ethinylestradiol 35 mug). Following hormones were measured: ghrelin, free testosterone, androstendione, dehydroepiandrosterone sulfate, 17-OH-progesterone and estradiol. RESULTS: The received results in both groups were compared with the control group (11 healthy women, mean age 26.0+/-2.6 yr). No statistically significant differences in ghrelin levels before (187.8+/-8.1 fmol/ml) and after the therapy (185.6+/-9.5 fmol/ml) were found. Similar results were received when two groups of women compared with the control (186.5+/-8.7 fmol/ml). No correlations between ghrelin and androgen levels were confirmed. CONCLUSIONS: Final conclusion is that there is no direct impact of ghrelin level on PCOS pathogenesis, however, its role in development of obesity, hyperinsulinemia and insulin resistance co-occurring with metabolic disorders syndrome cannot be excluded.

[Evaluation of the usefulness and effectiveness of anxiolytic therapies in neoplastic diseases].

UNLABELLED: Anxiety accompanies patients at all stages of severe somatic diseases as well in the course of diagnostic procedures. It affects significantly quality of life of these patients and their relations with their physicians. It may also induce or exacerbate wide range of somatic complaints. OBJECTIVE: Evaluation of usefulness of anxiolytic therapies in patients with diagnosed neoplastic diseases. Comparison of anti-anxiety and antidepressant effects of alprazolam and diazepam in patients treated with systemic chemotherapy. MATERIAL AND METHODS: Final analysis included 45 patients with various malignancies randomly assigned to receive alprazolam 3 x 0.5 mg or diazepam 3 x 2 mg. Anti-anxiety effects of both drugs was evaluated four times during the 21-day follow-up period at one week intervals with help of Clinical Global Impression scale (CGI), Hamilton Anxiety Rating Scale (HARS), Hospital Anxiety and Depression Scale (HADS). Analysis of these questionnaires was performed with Mann-Whitney test and Wilcoxon test. RESULTS: Statistically significant reduction of anxiety was found in both study groups. Alprazolam was proven to be significantly more effective than diazepam in reduction of anxiety (HARS, HADS) and depressive symptoms accompanying anxiety (HADS). Alprazolam vs. diazepam showed better tolerance by patients. CONCLUSIONS: Alprazolam effectively reduced anxiety in patients suffering from malignant diseases. Alprazolam was found to reduce depressive symptoms in patients with neurotic disorders whereas no effects of this kind were observed for diazepam.

[Hypothalamic-pituitary-thyroid axis in depression].

Depressed patients, although viewed as chemically euthyroid, have alterations in the function of hypothalamic-pituitary-thyroid axis including slight elevation of the serum thyroxine (T4), loss of the nocturnal TSH rise, blunted thyrotropin (TSH) response to thyrotropin-releasing hormone (TRH) stimulation and predisposition to autoimmune thyroiditis. Both hypothyroid and depressed patients share a number of clinical features in common. This is the reason that some research workers use the "brain hypothyroidism" hypothesis to explain the pathogenesis of depression. They suggest that depression is a state of local hypothyroidism in brain with normal peripheral thyroid hormone concentrations as a result of brain type II deiodinase inhibition and impaired transport T4 across the blood brain barrier. This theory seems to be compatible with the serotonin deficiency hypothesis of depression. Some studies confirm the existence of classical feedback between serotoninergic and hypothalamus-pituitary-thyroid systems. TRH remains under a constant inhibition by serotonin and reduced intracerebral serotonin concentration seen in depression will lead to increased TRH concentration in brain tissue. This mechanism is probably responsible for blunted TSH response to TRH stimulation.

The relation of serum adiponectin and leptin levels to metabolic syndrome in women before and after the menopause.

INTRODUCTION: It is well known that there is a higher prevalence of cardiovascular risk factors and metabolic syndrome (MS) in postmenopausal women. Recently it has become evident that adiponectin and leptin secreted by adipose tissue may be involved in the pathophysiology of MS. THE AIM OF THE STUDY: was to assess the effects of the menopause on the relationships between adiponectin and leptin and different cardiovascular and metabolic risk factors. MATERIALS AND METHODS: A total of 56 postmenopausal women and 75 premenopausal subjects were enrolled in this study. We measured blood pressure, BMI, waist circumference and WHR, triglycerides (TG), high density lipoprotein cholesterol (cHDL) levels and fasting glucose and applied the oral glucose tolerance test (OGTT). Women were categorised as having 0, 1, 2, 3 or more risk factors. The presence of at least 3 abnormalities was defined as MS. Serum was assayed for adiponectin and leptin by the radioimmunoassay (RIA) method. RESULTS: A decline in adiponectin was related to an increased number of MS variables in postmenopausal and premenopausal women. Postmenopausal women with MS had significantly lower adiponectin concentrations than premenopausal women with MS. Serum adiponectin concentrations were inversely correlated to leptin in postmenopausal women. In premenopausal women no clear relationships were found between serum leptin and the number of metabolic disturbances. In contrast to young women, postmenopausal women showed an increase in leptin secretion with a growing number of MS elements. Compared to premenopausal women with MS, postmenopausal women with MS had higher levels of leptin. We found associations between leptin and different risk factors, mainly in the postmenopausal group. When the presence of MS was used as a dependent variable (yes/no) and adiponectin, leptin and menopause status as independent factors, adiponectin and leptin remained significant variables related to MS. CONCLUSION: The significant role of adiponectin in the pathophysiology of MS in premenopausal and postmenopausal women is confirmed in this study. Leptin is correlated with several MS components but this adipocytokine appears to play a role only in postmenopausal women.

[Unique case of caecum plasmablastic lymphoma CD138(+) in patient with late diagnosed colon neuroendocrine carcinoma].

Neuroendocrine tumors are frequently associated with other primary malignancies. Plasmablastic lymphoma is a rare, aggressive neoplasm, derived from large B-cell, associated with human immunodeficiency virus infection. Plasmablastic lymphoma cells share many cytomorphologic and immunophenotypic features with plasmablastic cells, causing some diagnostic problems. We present a unique case of coexisting two very uncommon neoplasms: plasmablastic lymphoma and neuroendocrine carcinoma in 54-years-old men. This is the first report of caecum localization of plasmablastic lymphoma. Presented case images diagnostic problems in rare neoplasms.
