Rituximab for the first-line treatment of stage III/IV follicular non-Hodgkin's lymphoma.
This paper presents a summary of the evidence review group (ERG) report into the clinical and cost-effectiveness of rituximab for the first-line treatment of stage III/IV follicular non-Hodgkin's lymphoma (FNHL) based upon the manufacturer's submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The manufacturer's scope restricts the intervention to rituximab in combination with CVP (cyclophosphamide, vincristine and prednisolone) (R-CVP); the only comparator used was CVP alone. The evidence from the one included randomised controlled trial (RCT) suggests that the addition of rituximab to a CVP chemotherapy regimen has a positive effect on the outcomes of time to treatment failure, disease progression, overall tumour response, duration of response and time to new lymphoma treatment in patients with stage III/IV FNHL compared with CVP alone. ⋯ For the most extreme scenario (no OS gain) the ICER appears to remain below 30,000 pounds per QALY gained. On balance the evidence indicates that R-CVP is more cost-effective than CVP. The guidance issued by NICE in July 2006 as a result of the STA states that rituximab within its licensed indication (in combination with cyclophosphamide, vincristine and prednisolone) is recommended as an option for the treatment of symptomatic stage III/IV follicular non-Hodgkin's lymphoma in previously untreated patients.

This paper presents a summary of the evidence review group (ERG) report into the clinical and cost-effectiveness of infliximab for the treatment of moderate to severe plaque psoriasis, in accordance with the licensed indication, based on the evidence submission from Schering-Plough to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The outcomes stated in the manufacturer's definition of the decision problem were severity [Psoriasis Area and Severity Index (PASI) score], remission rates, relapse rates and health-related quality of life. The main evidence in the submission comes from four randomised controlled trials (RCT) comparing infliximab with placebo and eight RCTs comparing either etanercept or efalizumab with placebo. ⋯ The guidance issued by NICE in August 2007 as a result of the STA states that infliximab within its licensed indication is recommended for the treatment of adults with very severe plaque psoriasis, or with psoriasis that has failed to respond to standard systematic therapies. Infliximab treatment should be continued beyond 10 weeks in people whose psoriasis has shown an adequate response to treatment within 10 weeks. In addition, when using the Dermatology Life Quality Index (DLQI), care should be taken to take into account the patient's disabilities, to ensure DLQI continues to be an accurate measure.

Fludarabine phosphate for the first-line treatment of chronic lymphocytic leukaemia.
This paper presents a summary of the evidence review group (ERG) report into the clinical and cost-effectiveness of fludarabine phosphate or fludarabine plus cyclophosphamide for the first-line treatment of chronic lymphocytic leukaemia,based upon the evidence submission from Schering Health Care (SHC) to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The submission was of good quality with no major errors or omissions in the clinical evidence. Two published studies and seven abstracts were included in the company submission, which showed improvements in overall response and progression-free survival (PFS) and a higher complete response rate in the fludarabine containing arms; however, until the complete data are made available for evaluation these results must be interpreted with caution. ⋯ This brought into question the validity of the assumptions underpinning the extrapolation of data over a lifetime time horizon and showed that the ICER estimates submitted by the manufacturer were notcalculated correctly and uncertainty surrounding the decision problems was not expressed fully. Based on these analyses the ERG suggests that further evidence is needed to enable an accurate assessment to be made of the clinical and cost effectiveness of fludarabine as first-line treatment for chronic lymphocytic leukaemia. The guidance issued by NICE in December 2006 as a result of the STA states that fludarabine monotherapy,within its licensed indication, is not recommended for the first-line treatment of chronic lymphocytic leukaemia; no recommendations have been made with respect to fludarabine plus cyclophosphamide combination therapy because the current marketing authorisation does not specifically provide a recommendation that fludarabine should be used concurrently with other drugs for the treatment of chronic lymphocytic leukaemia.

Randomized Controlled Trial Multicenter Study Comparative StudyParacetamol and ibuprofen for the treatment of fever in children: the PITCH randomised controlled trial.
To establish the relative clinical effectiveness and cost-effectiveness of paracetamol plus ibuprofen compared with paracetamol and ibuprofen separately for time without fever, and the relief of fever-associated discomfort in young children who can be managed at home. ⋯ Young children who are unwell with fever should be treated with ibuprofen first, but the relative risks (inadvertently exceeding the maximum recommended dose) and benefits (extra 2.5 hours without fever) of using paracetamol plus ibuprofen over 24 hours should be considered. However, if two medicines are used, it is recommended that all dose times are carefully recorded to avoid accidentally exceeding the maximum recommended dose. Manufacturers should consider supplying blank charts for this purpose. Use of both medicines should not be discouraged on the basis of cost to either parents or the NHS. Parents and clinicians should be aware that fever is a relatively short-lived symptom, but may have more serious prognostic implications than the other common symptom presentations of childhood.

Review Comparative StudyA systematic review of presumed consent systems for deceased organ donation.
To examine the impact of presumed consent legislation on organ donation and to review data on attitudes to presumed consent among the public, professionals and any other stakeholders. ⋯ Presumed consent alone is unlikely to explain the variation in organ donation rates between different countries. A combination of legislation, availability of donors, transplantation system organisation and infrastructure, wealth and investment in health care, as well as underlying public attitudes to and awareness of organ donation and transplantation, may all play a role, although the relative importance of each is not clear. Further reviews could investigate the factors likely to modify donor rates, such as procedures for family involvement. The way in which families of any potential donor are approached is likely to be an important factor and a review of qualitative research examining the experience of relatives in this context would be useful.
