An allele of serum amyloid A1 associated with amyloidosis in both Japanese and Caucasians. 总被引:3,自引:0,他引:3

Serum amyloid A1 (SAA1), one of the two isotypes of acute phase SAA, is the predominant precursor to amyloid A (AA) protein, the chief constituent of fibrillar deposits in reactive (AA) amyloidosis. Prolonged hyperexpression of SAA protein accompanying chronic inflammation is critical to, but seems not to be sufficient for, the development of AA amyloidosis. Several previous studies have investigated the possibility of linkage between SAA1 exon 3 polymorphisms and susceptibility to amyloidosis. While the SAA1.1 allele was found to have a negative association with amylodosis in Japanese subjects, it showed a positive association in Caucasians. Moriguchi and colleagues recently showed that a single nucleotide polymorphism (SNP) at position -13 in the SAA1 5' flanking region was more strongly associated with amyloidosis than was the exon 3 polymorphism. To test whether this SNP may be an amyloidogenic factor common to Japanese and Caucasians, we have analyzed the SAA1 gene in amyloid and non-amyloid patients of both ethnic groups for the presence of T or C at position -13 and for exon 3 polymorphisms (SAA1.1, 1.3 or 1.5). The frequency of the -13T allele was 0.708 and 0.521 in Japanese rheumatoid arthritis patients with and patients without AA amyloidosis, respectively, and 0.536 and 0.196 in American Caucasian patients with AA amyloidosis and control subjects, respectively. In Caucasians, the -13T allele had a stronger association with amyloidosis than did the SAA1.1 allele. These findings suggest that -13T is a genetic background for AA amyloidosis in both Japanese and Caucasians and the difference in prevalence of AA amyloidosis in the two ethnic groups may be due, at least in part, to a difference in the frequency of the -13T SAA1 allele. 相似文献

Reoperative CABG using left thoracotomy: a tailored strategy 总被引:1,自引:0,他引:1
BACKGROUND: Reoperative coronary artery bypass grafting (CABG) through a left thoracotomy is a challenging operation with no one dominant approach. We developed a tailored strategy for this difficult group of patients, integrating the currently available newer technologies for each patient indication. METHODS: Between October 1991 and October 1999, 50 consecutive patients underwent reoperative CABG through a left thoracotomy. Age was 65 +/- 9 years, 40 (80%) were men, and preoperative ejection fraction was 40 +/- 13. In 36 patients (72%) the left internal mammary artery had been placed to the left anterior descending coronary artery during the primary CABG and in 25 of 36 patients (70%) this left internal mammary artery-left anterior descending coronary artery graft was patent. The mean duration from previous CABG was 8.0 +/- 4.8 years. Three approaches were used: (1) conventional cardiopulmonary bypass using fibrillatory or circulatory arrest (n = 33, 66%); (2) Heartport endoaortic balloon occlusion (n = 4, 8%); and (3) off-pump beating heart techniques (n = 13, 26%). RESULTS: The off-pump CABG technique was used in the majority of recent patients and 1 (7.7%) had to be converted to cardiopulmonary bypass due to hemodynamic instability. When cardiopulmonary bypass was used its duration was 122 +/- 59 minutes and mean temperature on bypass was 24 degrees +/- 6 degrees C. In the 4 patients in whom the Heartport system was used, the median endoaortic occlusion duration was 49 minutes. Patients received an average of 1.4 grafts/patient. In 60 of 70 patients (89%) distal anastomoses were performed to an anterolateral coronary target. There were 3 of 50 (6%) operative deaths, 2 in the conventional group and 1 in the endoaortic balloon occlusion group. The mean length of stay in the 47 survivors was 7.8 +/- 3.9 days (median, 7 days). CONCLUSIONS: Reoperative CABG by left thoracotomy remains a challenging operation. Several techniques, including off-pump CABG, conventional cardiopulmonary bypass, circulatory arrest, and endoaortic balloon occlusion, should be in the surgeon's armamentarium to allow a tailored approach for each operation based on patient indications. 相似文献
