Poor responders: does the protocol make a difference?

Abstract

An inadequate response to gonadotropins during in-vitro fertilization treatment may result in cycle cancellation, fewer embryos available for transfer and decreased pregnancy rates. For these reasons, numerous strategies to improve ovarian stimulation in poor responders have been proposed. These include variations in the type, dose and timing of gonadotropins, gonadotropin-releasing hormone agonists and gonadotropin-releasing hormone antagonists. Unfortunately, despite optimism generated by studies using retrospective controls, epidemiologically sound trials have been scarce. Indeed, of the three prospective randomized trials performed in poor responders to date no compelling advantage for one stimulation protocol over another has been established. Although this lack of improvement may reflect inadequate sample sizes, an alternative explanation is simply that the protocol, after a certain point, does not make a difference. Aside from oocyte donation, greater hope for poor responders may rest in aneuploidy screening, in-vitro oocyte maturation and cytoplasm/nuclear transfer.

Randomized, controlled trial of an easy-to-read informed consent statement for clinical trial participation: a study of the Eastern Cooperative Oncology Group.

PURPOSE: Studies have documented that the majority of consent documents for medical diagnosis and treatment are written at a reading level above that of the majority of the U.S. population. This study hypothesized that use of an easy-to-read consent statement, when compared with a standard consent statement, will result in higher patient comprehension of the clinical treatment protocol, lower patient anxiety, higher patient satisfaction, and higher patient accrual. METHODS: A randomized controlled trial was conducted in 44 institutions that were members or affiliates of three cooperative oncology groups. Institutions were randomly assigned to administer either an easy-to-read consent statement or the standard consent statement to patients being recruited to participate in selected cancer treatment trials. Telephone interviews were conducted with a total of 207 patients to assess study outcomes. RESULTS: Patients in the intervention arm demonstrated significantly lower consent anxiety and higher satisfaction compared with patients in the control arm. Patient comprehension and state anxiety were not affected by the intervention. Accrual rates into the parent studies also did not differ significantly between the two study groups. CONCLUSION: Clinical trial informed consent statements can be modified to be easier to read without omitting critical information. Patient anxiety and satisfaction can be affected by the consent document. The generalizability of these study results is limited by the characteristics of the patient sample. Ninety percent of the sample were white women, and the mean Rapid Estimate of Adult Literacy in Medicine score was approximately 64, indicating a literacy level at or above the ninth grade.

Fabry disease, an under-recognized multisystemic disorder: expert recommendations for diagnosis, management, and enzyme replacement therapy.

Fabry disease (alpha-galactosidase A deficiency) is an X-linked recessive lysosomal storage disorder. Although the disease presents in childhood and culminates in cardiac, cerebrovascular, and end-stage renal disease, diagnosis is often delayed or missed. This paper reviews the key signs and symptoms of Fabry disease and provides expert recommendations for diagnosis, follow-up, medical management, and the use of enzyme replacement therapy. Recommendations are based on reviews of the literature on Fabry disease, results of recent clinical trials, and expertise of the authors, all of whom have extensive clinical experience with Fabry disease and lysosomal storage disorders and represent subspecialties involved in treatment. All males and female carriers affected with Fabry disease should be followed closely, regardless of symptoms or treatment status. Clinical trials have shown that recombinant human alpha-galactosidase A replacement therapy--the only disease-specific therapy currently available for Fabry disease--is safe and can reverse substrate storage in the lysosome, the pathophysiologic basis of the disease. Enzyme replacement therapy in all males with Fabry disease (including those with end-stage renal disease) and female carriers with substantial disease manifestations should be initiated as early as possible. Additional experience is needed before more specific recommendations can be made on optimal dosing regimens for reversal; maintenance; and prevention of disease manifestations in affected males, symptomatic carrier females, children, and patients with compromised renal function.
