We studied HRQL and its relationship with treatment in a group of 441 patients with stage II or III COPD (age: 66.6 (SD: 8.3) years; FEV1: 32.4% (SD: 8.1%)) using the St George's Respiratory Questionnaire (SGRQ) and the 12-item short form (SF-12) Health Survey. The most prescribed drugs were ipratropium bromide (87.5%), inhaled corticosteroids (69.4%) and short-acting β-2 agonists (64.9%). Patients with stage III of the disease were receiving more drugs, particularly short-acting β-2 agonists (p = 0.002) and inhaled corticosteroids (p = 0.031). The use of theophyllines was associated with a worse total SGRQ score (β = 4.49; p < 0.001), although this negative association decreased with advanced age. A trend towards worse SGRQ scores was observed with the use of high doses of long-acting β-2 agonists (β = 3.22; p = 0.072). Patients receiving three drugs or more presented worse total SGRQ scores than patients receiving fewer drugs (β = 6.1, p < 0.001; and β = 7.64, p < 0.001, respectively). These findings suggest that the use of multiple drugs in the treatment of patients with COPD is associated with worse total SGRQ scores. The effect of drugs, their dosages and associations with other drugs on HRQL merit further research.

Neuropathological findings include severe widespread cerebral amyloid angiopathy, hippocampal plaques, and neurofibrillary tangles, similar to Alzheimer&#39;s disease. N-terminal sequence analysis of isolated leptomeningeal amyloid fibrils revealed homology to ABri, the peptide originated by a point mutation at the stop codon of gene BRI in familial British dementia. Molecular genetic analysis of the BRI gene in the Danish kindred showed a different defect, namely the presence of a 10-nt duplication (795-796insTTTAATTTGT) between codons 265 and 266, one codon before the normal stop codon 267. The decamer duplication mutation produces a frame-shift in the BRI sequence generating a larger-than-normal precursor protein, of which the amyloid subunit (designated ADan) comprises the last 34 C-terminal amino acids. This de novo-created amyloidogenic peptide, associated with a genetic defect in the Danish kindred, stresses the importance of amyloid formation as a causative factor in neurodegeneration and dementia.
