Declaration and Handling of Conflicts of Interest in Guidelines
Clinical guidelines are developed in order to support physicians and patients in specific clinical situations when decisions concerning diagnosis and treatment are made. Recommendations provided in guidelines are based on the findings of clinical studies and on expert opinion. Identical study findings may be evaluated differently depending on whether or not guideline authors have conflicts of interest (1). A conflict of interest is defined as a circumstance that gives rise to a risk that professional judgement or actions concerning a primary interest may be inappropriately influenced by a secondary interest (2, 3). A conflict of interest is therefore a state of affairs, not a biased evaluat…
Dopamine D2 Receptor Occupancy Estimated From Plasma Concentrations of Four Different Antipsychotics and the Subjective Experience of Physical and Mental Well-Being in Schizophrenia
Background Impaired subjective well-being in schizophrenia patients treated with antipsychotics has often been linked inter alia to the antidopaminergic effects of medication. Thus, it is important to capture the association between striatal dopamine D2 receptor occupancy (D2-RO) and global subjective well-being. We examined this association using data from our multicenter, randomized, double-blind Neuroleptic Strategy Study (NeSSy). Methods An innovative double randomization process was used for allocation of patients to the specific treatment groups. Plasma drug concentrations were measured after 6 and 24 weeks of treatment to obtain the estimated D2-RO (eD2-RO) relative to literature val…
