The effect of screening for cardio-renal risk factors on drug use in the general population.

Aim: To evaluate the effect of a cardio-renal screening programme on desired and undue drug use.

Methods: Data from the PREVEND cohort (Prevention of REnal and Vascular ENd-stage Disease) were used. The drug use of screened (randomly) selected subjects (n = 2650) was compared with unscreened subjects, matched for age and sex (n = 10 434).

The impact of hormonal contraceptives on blood pressure, urinary albumin excretion and glomerular filtration rate.

Aim: In short-term studies, hormonal contraceptives (HC) have been suggested to induce a rise in blood pressure (BP) and urinary albumin excretion (UAE), while the effect of HC in renal function (GFR) is still under debate. Data on long-term and withdrawal effects of HC use on these outcomes are, however, not available. We therefore studied whether the start and cessation of HC induce changes in BP, UAE and GFR.

Drug costs developments after patent expiry of enalapril, fluoxetine and ranitidine: a study conducted for the Netherlands.

Background: In order to increase price competition, government regulations focus on controlling drug costs. Drug costs after patent expiry are an area of particular interest because the substitution of branded medication with generics represents an opportunity for lowering drug costs. However, drug costs may not decrease after patent expiry, because of a lack of price competition and different national pricing systems.

Socio-economic aspects of extended STD screening in pregnancy.

Screening for sexually transmitted diseases (STDs) in early pregnancy is included in routine antenatal care for several infectious agents in many western European countries. Pharmaco-economics of these interventions have been evaluated. Currently, reconsideration of antenatal screening is ongoing, with explicit attention given to extending the STD testing to some other infectious agents, such as HIV and Chlamydia trachomatis (CT).
