One year in an Alaskan arthritis clinic.

During 1997 visits were made by 852 individuals to an arthritis clinic in Alaska serving predominantly Alaska Natives. Three hundred twenty- seven of these were seen for the first time. The ratio of women to men was 3:1. Rheumatoid Arthritis was the most common arthritic condition seen, followed by Degenerative Joint Disease and Spondyloarthropathies. Three hundred five Tlingit and 246 Eskimo made up 65% of the patients seen that year. Methotrexate was the most frequently used Disease Modifying Antirheumatic Drug but the other such drugs were prescribed as well. Recording demographic and clinical information on a portable computer at the time of visit provided record linkage and the data for this report and was used in Health Care Planning.

[Comparative study of epidemiology of spondylarthropathies in indigenous population of the Chukot peninsula and Alaska].

UNLABELLED: The paper sums up the many-year cooperative Russian-American studies of the epidemiology of spondylarthropathies in the arctic populations of the Chukot Peninsula and Alaska. AIM: Comparison of the epidemiology of spondylarthropathies in the indigenous population of the Chukot Peninsula and Alaska. MATERIALS AND METHODS: A universal design of investigation with the same diagnostic criteria was used in both countries. A total of 974 indigenous residents of the Chukot Peninsula were examined simultaneously, on the Alaska the sampling was formed as the residents applied for care. RESULTS: In both regions the study revealed 1) a high incidence of HLA-B27, reaching 40% in the Chukot Eskimos; 2) a similarly high incidence of spondylarthropathies varying from 2 to 3.4%; 3) a similar spectrum of diseases, including, primarily, ankylosing spondylarthritis and Reiter's syndrome and undifferentiated spondylarthropathies and (rarely) psoriatic arthritis. Among HLA-B27 positive adults, the incidence of spondylarthropathies in all groups is 4.2% and of ankylosing spondylarthritis 1.5%. CONCLUSION: A high incidence of spondylarthropathies, varying from 2 to 3.4%, was revealed in the Arctic populations of the Chukot Peninsula and Alaska with a high incidence of HLA-B27 antigen. Although the spectrum of detected diseases was similar in the two groups, ankylosing sponditis was more incident on the Chukot Peninsula, whereas on the Alaska reactive arthritis and nondifferentiated spondylarthropathies predominated, which can be explained by difference in the methods of examination.

T-cell receptor polymorphisms in Tlingit Indians with rheumatoid arthritis.

Rheumatoid arthritis (RA) develops as a result of the interaction of both genetic and environmental factors. Among the genes in humans that have been suggested as candidate susceptibility genes in RA are those encoding the T cell receptor for antigen (TCR). A high prevalence and early age of onset of RA has previously been reported in Alaskan Tlingit Indians. In this study, the frequency of seven different restriction fragment length polymorphisms (RFLPs) in the TCR alpha and beta gene complexes were measured in a population of Alaskan Tlingit Indians. No statistically significant differences were noted when the frequencies of these RFLPs were compared between Tlingits with RA and healthy controls (p > 0.05). These results do not support the hypothesis of an RA-susceptibility allele in the vicinity of these TCR alpha or beta genes. Since TCR RFLPs have not been extensively studied in native American populations, TCR polymorphism frequencies in the Tlingits were also compared to the frequencies observed in a second control group of healthy Caucasians. Statistically significant differences were observed in these comparisons implying a different distribution of individuals in these populations with different TCR repertoires.

HLA antigens in Tlingit Indians with rheumatoid arthritis.

HLA-DR4 has been described in association with rheumatoid arthritis (RA) in multiple populations. We have studied HLA antigens in Alaskan Tlingit Indians. HLA-DR4 was decreased in the RA group (n = 32) compared with controls (n = 62) (6% vs 21% p = 0.07). The predominant DR4 allele observed was DRB1*0403 (Dw13.1). The most striking observation in these studies was a marked predominance of the DRB1*1402 allele encoding Dw16 (DRw14). This allele was present in 91% of RA cases, but was also highly prevalent in controls (80%, OR = 2.4 p = 0.20). DRB1*1402 only was observed in 47% of cases and 31% of controls. The DRB3*0101 (DRw52), and the DQA*0501 and DQB*0301 alleles encoding a subset of DQw3 were associated with DRB1*1402 in cases and in controls. HLA-Bw62 was increased in RA cases (28%) compared with controls (8%) (OR = 4.5, p = 0.01, corrected p = ns).

Developing a computer laboratory for neurotologic diagnosis.

The authors, with the help of a community hospital engineering staff, constructed a modern neurotological testing facility capable of performing on-line computer measurements of vestibulo-oculomotor, visual vestibulo-oculomotor, smooth pursuit, saccade, and optokinetic reflexes. The laboratory was built from component parts and uses a Digital Corporation laboratory computer. Programs from the UCLA Human Vestibular Laboratory were modified to work with the new laboratory. Construction and program modification cost $60,000 and was completed in seven months. The laboratory was working at full capacity six months after construction testing patients with suspected neurotologic and neurologic disorders. The procedures of construction as well as the financial and safety problems are discussed.
