Defer or treat? Reasons for treatment decisions in patients with chronic hepatitis C genotype 1 in the early era of directly acting antiviral agents

2013

Abstract Background In chronic genotype 1 hepatitis C, telaprevir or boceprevir plus peginterferon and ribavirin have become the new standard of care. Aim of this study was to identify factors contributing to the decision whether to defer or treat with the current triple regimens. Methods Prospective assessment of eight parameters on 0-4-point scales by the attending physician at a German tertiary referral centre between 1st September 2011 and 31st December 2012. Results 307 patients were evaluated at least once by one of the 11 hepatologists involved; 267 patients were considered, but only 163 were recommended to receive triple therapy. Multivariate regression analysis revealed that a high…

Treatment of idiopathic oligozoospermia with tamoxifen--a randomized controlled study.

1992

There is no conclusive evidence of the usefulness of tamoxifen in the treatment of idiopathic oligozoospermia (OAT-syndrome), as it has been used mostly in uncontrolled studies. We herein report on the controlled treatment of OAT-syndrome with tamoxifen versus placebo following a randomized design. Seventy-six men with sperm counts of 2-20 x 10(6) ml-1, sperm motility of 20-50%, and sperm morphology (abnormal cells) between 50 and 80% were involved in the study. Patients with varicocele, a history of testicular maldescent or genital inflammation were excluded. Thirty-nine patients received tamoxifen (30 mg daily), 37 patients placebo. There was a statistically significant increase in the me…

De novo 15q21.1q21.2 deletion identified through FBN1 MLPA and refined by 244K array-CGH in a female teenager with incomplete Marfan syndrome

2010

International audience; Interstitial deletions involving the 15q21.1 band are very rare. Only 4 of these cases have been studied using molecular cytogenetic techniques in order to confirm the deletion of the whole FBN1 gene. The presence of clinical features of the Marfan syndrome (MFS) spectrum associated with mental retardation has been described in only 2/4 patients. Here we report on a 16-year-old female referred for suspicion of MFS (positive thumb and wrist sign, scoliosis, joint hyperlaxity, high-arched palate with dental crowding, dysmorphism, mitral insufficiency with dystrophic valve, striae). She had therefore 3 minor criteria according to the Ghent nosology. She also had speech …

Gene expression profiling of peripheral blood mononuclear cells in endometriosis identifies genes altered in non-gynaecologic chronic inflammatory di…

2011

background: Pelvic inflammatory phenomena have been suggested as critical players in the natural history of endometriosis. However, to what extent these events could affect the systemic immunologic status remains to be clarified. Here, we compared the gene expression profile in peripheral blood mononuclear cells from endometriosis patients in the severe diseased stage with the profile after a conventional surgical treatment for removal of endometriotic lesions and adhesions.   methods: Microarray analysis included four patients suffering from severe endometriosis in which blood samples were obtained few days before the surgical intervention and again 6 months later. Real-time quantitative…

Combination of osteopontin and activated leukocyte cell adhesion molecule as potent prognostic discriminators in HER2- and ER-negative breast cancer.

2010

Background: To analyse the discriminative impact of osteopontin (OPN) and activated leukocyte cell adhesion molecule (ALCAM), combined with human epidermal growth factor 2 (HER2) and oestrogen receptor (ER) in breast cancer. Methods: Osteopontin, ALCAM, HER2 and ER mRNA expression in breast cancer tissues of 481 patients were analysed (mRNA microarray analysis, kinetic RT–PCR). Hierarchical clustering was performed in training cohort A (N=100, adjuvant treatment) and validation cohorts B (N=200, no adjuvant treatment, low-risk) and C (N=181, adjuvant treatment, high-risk). Results: Negative/low ER and HER2, high OPN and low ALCAM mRNA expression helped to identify patients at particularly h…

Gluten affects epithelial differentiation-associated genes in small intestinal mucosa of coeliac patients

2007

Summary In coeliac disease gluten induces an immunological reaction in genetically susceptible patients, and influences on epithelial cell proliferation and differentiation in the small-bowel mucosa. Our aim was to find novel genes which operate similarly in epithelial proliferation and differentiation in an epithelial cell differentiation model and in coeliac disease patient small-bowel mucosal biopsy samples. The combination of cDNA microarray data originating from a three-dimensional T84 epithelial cell differentiation model and small-bowel mucosal biopsy samples from untreated and treated coeliac disease patients and healthy controls resulted in 30 genes whose mRNA expression was simila…

Retinal myelinated nerve fibers associated with macular pseudohole

2008

We report the case of a 24-year-old woman who presented unilateral extensive peripapillary myelinated nerve fibers associated with macular pseudohole and bilateral low myopia. Visual acuity, slit lamp biomicroscopy, automated perimetry, fundus color photography, and optical coherence tomography (Stratus® OCT) were performed. We discuss the clinical findings and diagnostic details of unilateral extensive peripapillary myelinated nerve fibers associated with macular pseudohole.

The oligomenorrhoic phenotypes of polycystic ovary syndrome are characterized by a high visceral adiposity index: a likely condition of cardiometabol…

2011

BACKGROUND: Women with polycystic ovary syndrome (PCOS) frequently exhibit central obesity, glucose intolerance, atherogenic dys- lipidemia and hypertension, which are characteristic features of a condition of cardiometabolic risk. Our objective was to investigate the relationship between visceral adiposity index (VAI) and phenotypic characteristics in women with PCOS. METHODS: We conducted a cross-sectional case-control study in our Endocrinology Outpatients Clinic. A total of 220 women with PCOS (Rotterdam definition) and I44 age- and BMI-matched healthy women were studied. We evaluated hyperandrogenemia and clinical hyperandrogenism, ovarian morphology, hypothalamic-hypophyseal axis and …

Endometrial receptivity is affected in women with high circulating progesterone levels at the end of the follicular phase: a functional genomics anal…

2011

Elevated serum progesterone levels at the end of the follicular phase in controlled ovarian stimulation (COS) leads to a poorer ongoing pregnancy rate in IVF cycles due to reduced endometrial receptivity. The objective of this study was to use microarray technology to compare endometrial gene expression profiles at the window of implantation according to the levels of circulating progesterone.For this prospective cohort study, microarray data were obtained from endometrial biopsies from 12 young healthy oocyte donors undergoing COS with pituitary suppression by either gonadotrophin-releasing hormone (GnRH) agonists or antagonists, and recombinant FSH. On the day of recombinant chorionic gon…

Effect of an intrauterine device on the gene expression profile of the endometrium.

2006

The human endometrium acquires the ability to allow embryo attachment just for a specific period of time during each menstrual cycle. Understanding of the opposite functional status, referred to as refractoriness, can potentially be used to improve receptivity in infertile patients or as an interceptive approach to prevent gestation.The objective of the study was to analyze the endometrial gene expression profile induced by an inert intrauterine device (IUD) at the time of implantation.We used a microarray containing more than 16,000 cDNAs to investigate the gene expression profile of receptive vs. refractory endometrium in the same women induced by the presence of an IUD. We compared the g…
