[Impact of universal varicella vaccination in Germany: an epidemiological and economic analysis].

Varicella is a highly contagious viral disease which mainly affects young children and usually is perceived as infection with a mild disease course. However, there is increasing evidence indicating that the morbidity and mortality as well as the economic impact associated with varicella are significant. While universal childhood vaccination against varicella is currently not recommended in Germany, the availability of safe and efficacious vaccines offers the opportunity for preventive intervention. Detailed and reliable data on the consequences of varicella and the possible impact of a universal vaccination program are missing to date for Germany. In order to generate this information, we conducted a comprehensive evaluation. The objective was to quantify the medical consequences and the economic impact of varicella on third-party payers and the society by means of a model analysis, and particularly to assess the effects of various universal vaccination strategies. The study confirms that varicella represents a significant health and economic burden in Germany. Following mathematical modelling, universal varicella vaccination for children at the age of 12-18 months could prevent more than 82 % of cases and complications on average per year. Economically, universal vaccination would lead to net cost savings not only for the society but also for the third-party payers. From these findings it can be concluded that universal varicella vaccination is a strategy which should be encouraged, from a medical, epidemiological, but also economic viewpoint.

Analysis of adverse effects among patients with essential hypertension receiving an ACE inhibitor or a beta-blocker.

Evaluation of safety and efficacy of new drugs is based largely on data from clinical trials involving a limited number of patients. This approach does not necessarily detect the rare adverse events that may only be observed when very large numbers of patients are studied. Consequently, we designed a double-blind 12-week trial comparing the new angiotensin-converting enzyme (ACE) inhibitor, quinapril (n = 5,053), with a well-established beta-adrenergic receptor blocker, metoprolol (n = 506). Essentially hypertensive patients (diastolic blood pressure 95-114 mm Hg) received either 10 mg quinapril or 50 mg metoprolol once daily, and the doses were doubled at 4-week intervals to a maximum of 40 and 200 mg, respectively, in nonresponders. Responder rates were similar under both regimens. Adverse events were assessed by interview as well as by a standard questionnaire. The overall prevalence of adverse events reported by standard questionnaire was higher than that reported spontaneously during interviews. With respect to typical ACE inhibitor adverse reactions (e.g. cough and taste disturbances), there was no difference between quinapril and metoprolol independent of the mode of reporting. In summary, both drugs showed comparable overall tolerance and safety. The discrepancy between spontaneously reported and questionnaire-reported adverse events was noteworthy, and this finding prevailed in a volunteer group of 327 patients who were treated with quinapril for 52 weeks. Thus, a questionnaire is of great significance in addition to the patient history/interview in a large-scale, double-blind study designed to learn about details of drug safety.
