[Treatment of sudden hearing loss through Fibrinogen/LDL-apheresis. A prospective, randomized multicenter trial]. / Behandlung des Hörsturzes durch Fibrinogen-LDL-Apherese. Eine prospektive randomisierte Multizenterstudie.

INTRODUCTION: Sudden sensorineural hearing loss (SSHL) is thought to be of various origins. Disturbances of microcirculation, autoimmune pathology and viral infection are among the most likely causes. Acute reduction of plasma fibrinogen and serum LDL positively influences hemorheology and endothelial function and might thus be an effective therapy for SSHL. OBJECTIVE: To test the hypothesis that fibrinogen/LDL-apheresis is as effective or superior to conventional therapy with plasma expanders and prednisolone in the treatment of SSHL. DESIGN: controlled, prospective, randomized, multicenter trial. SETTING AND PATIENTS: 201 patients were recruited from 01/2000 to 6/2001 at the University Clinics of Munich, Berlin, Hamburg and Bochum. Inclusion criteria was sudden sensorineural hearing loss of unknown origin within 6 days of onset. INTERVENTIONS: Single fibrinogen/ LDL-apheresis infusion of prednisolone (250 mg, tapered by 25 mg daily), hydroxyethyl starch (500 ml, 6%) and pentoxifylin (400 mg/day). MAIN OUTCOMES: Improvement of pure tone thresholds 48 h after onset of therapy. RESULTS: Over all improvement of pure tone thresholds in the fibrinogen/ LDL-apheresis treated patients is slightly but not significantly better than in the standard therapy group. After 48 h, 50% speech perception in the fibrinogen/ LDL-apheresis group (21.6+/-20.1 dB) is significantly (p<0.034) better than in the standard group (29.3+/-29.4 dB). Patients with plasma fibrinogen levels of more than 295 mg/dl have a substantial and significantly (p<0.005) better improvement of speech perception (15.3+/-17.3 dB) than standard treated patients (6.1+/-10.4 dB). CONCLUSIONS: Fibrinogen/LDLapheresis is at least equally effective compared to prednisolone treatment in sudden hearing loss. Selected patients with plasma fibrinogen of more than 295 mg/dl improve significantly better when treated with fibrinogen/LDLapheresis.

[Drug substitution treatment of heroin dependent patients with codeine preparations--treatment effects from the viewpoint of the physicians and patients]. / Substitutionsbehandlung von Heroinabhängigen mit codeinhaltigen Präparaten--Behandlungseffekte aus Sicht der Arzte und Patienten.

The controversy caused by the debate on treatment and substitution strategies in drug addiction is unchanged. This is particularly true concerning the use of codein-based drugs in the substitution of heroin abusers. However, only a few studies on the effects of this old and widely used method of substitution have been carried out. This article presents one retrospective and prospective study on the effects of the codein-based substitution in heroin abusers (n = 416). With respect to the issues addressed by this study such as somatic and psychic health, social integration, delinquincy and consumption patterns, patients as well as clinicians report an improvement in general health and fewer of the problems usually associated with heroin abuse, similar to the results from substitution treatment elsewhere.

Lovastatin versus bezafibrate: efficacy, tolerability, and effect on urinary mevalonate.

Lovastatin and benzafibrate have proved effective in lowering low-density-lipoprotein (LDL) cholesterol and elevating high-density-lipoprotein (HDL) cholesterol. We compared their tolerability, safety, and effects on lipoproteins and urinary mevalonate excretion in a short-term study. Forty patients with primary hypercholesterolemia were enrolled in a single-blind randomized study with a diet/placebo period of 8 weeks and a treatment period of 12 weeks. Twenty patients received lovastatin (final average dose 70.5 mg/day), and 20 patients received bezafibrate 400 mg/day. LDL cholesterol was lowered by 35% (from 323 to 208 mg/dl) with lovastatin and by 8% (from 289 to 264 mg/dl) with benzafibrate. HDL cholesterol increased by 21 and 20% with lovastatin and benzafibrate, respectively. Twenty-four-hour urinary mevalonic acid output decreased by 37% during treatment with lovastatin and by 2% during treatment with bezafibrate. Thus, the lowering of cholesterol by lovastatin, but not by bezafibrate, can be attributed to inhibition of HMG CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase. Both lovastatin and bezafibrate are well tolerated.
