Summary Background Statins lower high-sensitivity C-reactive protein (hsCRP) and cholesterol concentrations, and hypothesis generating analyses suggest that clinical outcomes improve in patients ...given statins who achieve hsCRP concentrations less than 2 mg/L in addition to LDL cholesterol less than 1·8 mmol/L (<70 mg/dL). However, the benefit of lowering both LDL cholesterol and hsCRP after the start of statin therapy is controversial. We prospectively tested this hypothesis. Methods In an analysis of 15 548 initially healthy men and women participating in the JUPITER trial (87% of full cohort), we prospectively assessed the effects of rosuvastatin 20 mg versus placebo on rates of non-fatal myocardial infarction, non-fatal stroke, admission for unstable angina, arterial revascularisation, or cardiovascular death (prespecified endpoints) during a maximum follow-up of 5 years (median 1·9 years), according to on-treatment concentrations of LDL cholesterol (≥1·8 mmol/L or <1·8 mmol/L) and hsCRP (≥2 mg/L or <2 mg/L). We included all events occurring after randomisation. This trial is registered with ClinicalTrials.gov , number NCT00239681. Findings Compared with placebo, participants allocated to rosuvastatin who achieved LDL cholesterol less than 1·8 mmol/L had a 55% reduction in vascular events (event rate 1·11 vs 0·51 per 100 person-years; hazard ratio HR 0·45, 95% CI 0·34–0·60, p<0·0001), and those achieving hsCRP less than 2 mg/L a 62% reduction (event rate 0·42 per 100 person-years; HR 0·38, 95% CI 0·26–0·56, p<0·0001). Although LDL cholesterol and hsCRP reductions were only weakly correlated in individual patients ( r values <0·15), we recorded a 65% reduction in vascular events in participants allocated to rosuvastatin who achieved both LDL cholesterol less than 1·8 mmol/L and hsCRP less than 2 mg/L (event rate 0·38 per 100 person-years; adjusted HR 0·35, 95% CI 0·23–0·54), versus a 33% reduction in those who achieved one or neither target (event rate 0·74 per 100 person-years; HR 0·67, 95% CI 0·52–0·87) (p across treatment groups <0·0001). In participants who achieved LDL cholesterol less than 1·8 mmol/L and hsCRP less than 1 mg/L, we noted a 79% reduction (event rate 0·24 per 100 person-years; HR 0·21, 95% CI 0·09–0·52). Achieved hsCRP concentrations were predictive of event rates irrespective of the lipid endpoint used, including the apolipoprotein B to apolipoprotein AI ratio. Interpretation For people choosing to start pharmacological prophylaxis, reduction in both LDL cholesterol and hsCRP are indicators of successful treatment with rosuvastatin. Funding AstraZeneca.
Abstract Background Collaborative group intervention (CGI) in patients with functional somatic syndromes (FSS) has been shown to improve mental quality of life. Objective To analyse incremental ...cost-utility of CGI compared to enhanced medical care in patients with FSS. Methods An economic evaluation alongside a cluster-randomised controlled trial was performed. 35 general practitioners (GPs) recruited 300 FSS patients. Patients in the CGI arm were offered 10 group sessions within 3 months and 2 booster sessions 6 and 12 months after baseline. Costs were assessed via questionnaire. Quality adjusted life years (QALYs) were calculated using the SF-6D index, derived from the 36-item short-form health survey (SF-36). We calculated patients
'
net-monetary-benefit (NMB), estimated the treatment effect via regression, and generated cost-effectiveness acceptability curves. Results Using intention-to-treat analysis, total costs during the 12-month study period were 5
777EUR in the intervention, and 6
858EUR in the control group. Controlling for possible confounders, we found a small, but significant positive intervention effect on QALYs (+ 0.017; p = 0.019) and an insignificant cost saving resulting from a cost-increase in the control group (
− 10.5%; p = 0.278). NMB regression showed that the probability of CGI to be cost-effective was 69% for a willingness to pay (WTP) of 0EUR/QALY, increased to 92% for a WTP of 50,000EUR/QALY and reached the level of 95% at a WTP of 70,375EUR/QALY. Subgroup analyses yielded that CGI was only cost-effective in severe somatic symptom severity (PHQ-15 ≥ 15). Conclusion CGI has a high probability to be a cost-effective treatment for FSS, in particular for patients with severe somatic symptom severity.
