Randomized investigation of increased dialyzer membrane hydrophilicity on hemocompatibility and performance.

Background: Hemodialyzers should efficiently eliminate small and middle molecular uremic toxins and possess exceptional hemocompatibility to improve well-being of patients with end-stage kidney disease. However, performance and hemocompatibility get compromised during treatment due to adsorption of plasma proteins to the dialyzer membrane. Increased membrane hydrophilicity reduces protein adsorption to the membrane and was implemented in the novel FX CorAL dialyzer.

Hemodiafiltration: Technical and Medical Insights.

Despite the significant medical and technical improvements in the field of dialytic renal replacement modalities, morbidity and mortality are excessively high among patients with end-stage kidney disease, and most interventional studies yielded disappointing results. Hemodiafiltration, a dialysis method that was implemented in clinics many years ago and that combines the two main principles of hemodialysis and hemofiltration-diffusion and convection-has had a positive impact on mortality rates, especially when delivered in a high-volume mode as a surrogate for a high convective dose. The achievement of high substitution volumes during dialysis treatments does not only depend on patient characteristics but also on the dialyzer (membrane) and the adequately equipped hemodiafiltration machine.

Lifestyle aspects in a contemporary middle-European cohort of patients undergoing androgen deprivation therapy for advanced prostate cancer: data from the non-interventional LEAN study.

Androgen deprivation therapy (ADT) in men with prostate cancer (PCa) is associated with significant side effects. With the transition of PCa from a foudroyant course to a chronic disease, managing these side effects has become increasingly important. There is growing evidence that nutritional changes and physical activity are beneficial in these patients.

Impact of Hydrophilic Modification of Synthetic Dialysis Membranes on Hemocompatibility and Performance.

The dialyzer is the core element in the hemodialysis treatment of patients with end-stage kidney disease (ESKD). During hemodialysis treatment, the dialyzer replaces the function of the kidney by removing small and middle-molecular weight uremic toxins, while retaining essential proteins. Meanwhile, a dialyzer should have the best possible hemocompatibility profile as the perpetuated contact of blood with artificial surfaces triggers complement activation, coagulation and immune cell activation, and even low-level activation repeated chronically over years may lead to undesired effects.

Randomized comparison of three high-flux dialyzers during high-volume online hemodiafiltration-the comPERFORM study.

Background: Dialyzers should be designed to efficiently eliminate uraemic toxins during dialysis treatment, given that the accumulation of small and middle molecular weight uraemic solutes is associated with increased mortality risk of patients with end-stage renal disease. In the present study we investigated the novel FX CorAL dialyzer with a modified membrane surface for performance during online hemodiafiltration (HDF) in a clinical setting.

Methods: comPERFORM was a prospective, open, controlled, multicentric, interventional, crossover study with randomized treatment sequences.

Effectiveness and Distribution of Testosterone Levels within First Year of Androgen Deprivation Therapy in a Real-World Setting: Results from the Non-Interventional German Cohort LEAN Study.

Background: Observational studies generate information on real-world therapy and complement data from prospective randomized trials. LEAN is an open-label, non-interventional, multi-centre, German cohort study on leuprorelin in routine clinical practice.

Objectives: To extend knowledge on the use, effectiveness, and tolerability of HEXAL/Sandoz leuprorelin (in this article, the term Leuprone® HEXAL® covers Leuprorelin Sandoz® as well) solid implant in patients with prostate cancer (PCa) in a real-world setting.

Tolerability and effectiveness of an antitrauma cream with comfrey herb extract in pediatric use with application on intact and on broken skin.

Objective: The safety of comfrey herbal cream application to broken skin is still a matter of regulatory debate. It was therefore examined in children with intact and with broken skin treated for blunt traumas and sports injuries, with the aim of collecting data for pharmacovigilance and clinical safety assessments.

Methods: A total of 712 children (386 children with intact skin and 326 children with abrasions and superficial wounds) were openly treated for up to 2 weeks with 1-5 applications daily of comfrey herb cream after presenting for blunt traumas and sports accidents.

Survey to estimate the prevalence of type 2 diabetes mellitus in hospital patients in Germany by systematic HbA1c measurement upon admission.

Objectives: The objective of this survey was to estimate the prevalence of type 2 diabetes mellitus (T2DM) in hospitalised patients ≥55 years based on routine HbA1c measurement upon admission, using the diagnosis algorithm according to the German National Diabetes Care Guideline.

Design: Non-interventional survey.

Setting: Four German maximum care hospitals.

Comparative Study with a Lip Balm Containing 0.5% Propolis Special Extract GH 2002 versus 5% Aciclovir Cream in Patients with Herpes Labialis in the Papular/Erythematous Stage: A Single-blind, Randomized, Two-arm Study.

STW 5 (Iberogast®; Steigerwald Arzneimittelwerk GmbH, Darmstadt, Germany) contains nine plant extracts and possesses well-documented overall efficacy in functional gastrointestinal disorders (FGID). Little is known about the onset of symptom relief. Twenty-nine centers in Germany recruited 272 patients with established FGID.

Prevention and treatment of chemotherapy-induced neutropenia with the biosimilar filgrastim: a non-interventional observational study of clinical practice patterns.

Background: Biosimilars are similar but non-identical versions of existing biological drugs. The HEXAFIL study was an observational study that assessed the clinical usage, safety and efficacy of the biosimilar filgrastim in routine clinical practice in Germany.

Patients And Methods: A total of 1,337 cancer patients received the biosimilar filgrastim for primary prophylaxis (PP), secondary prophylaxis (SP) or interventional treatment (TX) plus chemotherapy.

[Drugs in chronic venous insufficiency--the challenge of demonstrating clinical efficacy].

Approximately 90% of German adults show alterations of their lower limb veins; about every fifth suffers from symptoms of chronic venous insufficiency (CVI). With compression therapy showing low compliance, CVI oedemas and accompanying subjective symptoms are frequently treated with anti-oedematous drugs of herbal origin. A guideline outlines the requirements for clinical studies with CVI drugs.

STW 5 (Iberogast®)--a safe and effective standard in the treatment of functional gastrointestinal disorders.

Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are frequent disorders affecting quality of life. They often require long-term treatment. Abdominal symptoms of both disorders can overlap, making differential diagnosis and treatment challenging.
