ABSTRACT
OBJECTIVES: Primary angiitis of the central nervous system (PACNS) is a vasculitis confined to the brain and spinal cord, which often presents with severe cognitive and functional deficits. Despite progress in diagnosis, little is still known about long-term outcomes. Our aim was to evaluate long-term functional capabilities, quality of life, and depression, and to determine the effect of treatment duration on patient outcomes. METHODS: We identified patients by ICD-9 codes for cerebral angiitis, and included them if they met two of the three following criteria: inflammatory cerebrospinal fluid (CSF), cerebral angiogram typical of vasculitis, or findings of vasculitis on pathologic examination of brain tissue. Disability was assessed by the Barthel Index, quality of life was assessed by EuroQol, and depression was assessed with Patient Health Questionnaire. RESULTS: Seventy-eight patients met the inclusion criteria, of which 27 responded to the questionnaire (34.6%). Mean follow-up of those who responded was 5.5 years (± 4.7). Nineteen of 27 patients (70.4%) had mild disability; meanwhile, 5 (18.5%) had severe disability. Fourteen of 27 patients (51.9%) had no mobility problem, 18 (66.7%) had no problems with self-care, 15 (55.6%) had no problems with usual activities, 14 (51.9%) had no pain, and 8 (29.6%) had no anxiety. Approximately 70% of patients had minimal or no depression. CONCLUSIONS: This is the longest reported follow-up of patients with PACNS described in the literature to date. Most patients had mild long-term disability and minimal to no depression, which may be reflective of treatment advances.

The aim of the Finland-United States Investigation of NIDDM Genetics (FUSION) study is to identify genes that predispose to type 2 diabetes or are responsible for variability in diabetes-related traits via a positional cloning and positional candidate gene approach. In a previously published genome-wide scan of 478 Finnish affected sibling pair (ASP) families (FUSION 1), the strongest linkage results were on chromosomes 20 and 11. We now report a second genome-wide scan using an independent set of 242 Finnish ASP families (FUSION 2), a detailed analysis of the combined set of 737 FUSION 1 + 2 families (495 updated FUSION 1 families), and fine mapping of the regions of chromosomes 11 and 20. The strongest FUSION 2 linkage results were on chromosomes 6 (maximum logarithm of odds score [MLS] = 2.30 at 95 cM) and 14 (MLS = 1.80 at 57 cM). For the combined FUSION 1 + 2 families, three results were particularly notable: chromosome 11 (MLS = 2.98 at 82 cM), chromosome 14 (MLS = 2.74 at 58 cM), and chromosome 6 (MLS = 2.66 at 96 cM). We obtained smaller FUSION 1 + 2 MLSs on chromosomes X (MLS = 1.27 at 152 cM) and 20p (MLS = 1.21 at 20 cM). Among the 10 regions that showed nominally significant evidence for linkage in FUSION 1, four (on chromosomes 6, 11, 14, and X) also showed evidence for linkage in FUSION 2 and stronger evidence for linkage in the combined FUSION 1 + 2 sample.
