  • Strategic roadmap for an early diagnosis of Alzheimer's disease based on biomarkers

    • The diagnosis of Alzheimer's disease can be improved by the use of biological measures. Biomarkers of functional impairment, neuronal loss, and protein deposition that can be assessed by neuroimaging (ie, MRI and PET) or CSF analysis are increasingly being used to diagnose Alzheimer's disease in research studies and specialist clinical settings. However, the validation of the clinical usefulness of these biomarkers is incomplete, and that is hampering reimbursement for these tests by health insurance providers, their widespread clinical implementation, and improvements in quality of health care. We have developed a strategic five-phase roadmap to foster the clinical validation of biomarkers in Alzheimer's disease, adapted from the approach for cancer biomarkers. Sufficient evidence of analytical validity (phase 1 of a structured framework adapted from oncology) is available for all biomarkers, but their clinical validity (phases 2 and 3) and clinical utility (phases 4 and 5) are incomplete. To complete these phases, research priorities include the standardisation of the readout of these assays and thresholds for normality, the evaluation of their performance in detecting early disease, the development of diagnostic algorithms comprising combinations of biomarkers, and the development of clinical guidelines for the use of biomarkers in qualified memory clinics.

  • Teaching non-specialist health care professionals how to identify the atypical mole syndrome phenotype : a multinational study
  • 2000
  • Ingår i: British Journal of Dermatology. - : Oxford University Press (OUP). - 0007-0963 .- 1365-2133. ; 142:2, s. 331-337
  • Tidskriftsartikel (refereegranskat)abstract
    • The atypical mole syndrome (AMS) phenotype is the strongest known risk factor for cutaneous melanoma but recognition of the phenotype has been claimed to be problematic and to require specialist assessment. This study determined the ability of previously unskilled doctors and nurses in five countries to recognize the phenotype after brief training. The system used was the AMS scoring system. This incorporates melanocytic naevus counts, clinical atypia of naevi and distribution of naevi. The agreement in scoring between the dermatologist and trained personnel was determined in 986 patients; overall agreement in diagnosis was 94·5% (kappa 0·70, P < 0·0001). The kappa scores in different countries ranged from 0·65 to 0·77 for individual naevus characteristics, indicative of good agreement. Accurate diagnosis of the atypical mole syndrome phenotype is possible by non-specialists. This has implications for collaborative studies of naevi, for screening and for both primary and secondary prevention of melanoma.
