A 40-year-old female who had been treated with steroid for 10 years because of systemic lupus erythematosus (SLE) was admitted to our department for triple-vessel disease with LMT lesion. She underwent bilateral internal mammary artery grafting to the right ventricular branch of RCA and the No. 7 segment of LAD. Intraoperative free flow was 70 ml/min in both bypass grafts. She dropped to severe shock with a high fever of 40 degrees C and decreased the white blood cell count of 900/mm3 on the 6th postoperative day. These clinical and laboratory findings were suggestive of rebound phenomenon of SLE or withdrawal syndrome of steroid therapy. She was treated with pulse therapy of methyl-prednisolone and her condition improved in two weeks. Histological findings of the right internal mammary artery revealed stenotic lesion of about 50%, but on June 24, 1988, postoperative angiography showed a good patency of both internal mammary arteries. Only a few reports of successful attempt of coronary artery bypass grafting for coronary lesion due to SLE are available in the literature. Some important problems concerning the surgical treatment as well as the therapy of steroid involved in this case were discussed.

Using a computed image analyser, coronary arteries from 50 autopsied patients with systemic lupus erythematosus (SLE) were examined on the three vessels (RCA, LAD, LCX) and compared with those of age-matched controls. The intima of coronary artery was significantly thickened much more in the case of SLE than in the case of age-matched controls. This was statistically significant (p less than 0.01). Hypertension and glomerulonephritis did not but corticosteroid therapy had an influence on the development of intimal thickening ratio of the coronary arteries in SLE patients. The mean intimal thickening ratio of the coronary arteries in the patients with SLE and without corticosteroid therapy was larger than that of patients with corticosteroid therapy (p less than 0.1). It appears possible to conclude that inflammatory change of SLE itself is one of the promoting factors of coronary atherosclerosis.

A study of 24 patients with IgA deposition at the BMZ of the skin showed that five conditions could be recognized: 1) linear IgA bullous dermatosis in adults (LAD, 7 cases); 2) linear IgA and IgG bullous dermatosis in adults (LAGD, 10 cases); 3) chronic bullous disease of childhood (CBDC, 3 cases); 4) dermatitis herpetiformis (DH, 1 case), and 5) systemic lupus erythematosus (SLE, 3 cases). Histopathologically, 5 of 7 patients with LAD were similar to the DH group, but 7 of 10 patients with LAGD were similar to the BP group. Half the patients with LAD and LAGD had oral lesions, and most of them had excellent responses to dapsone and Tripterygium Wilfordii, but the patients with CBDC did not respond to these treatments. In the patients with LAD and LAGD, the positivity rates of IgA anti-BMZ antibodies examined by indirect immunofluorescence (IIF) on intact skin and NaCl split skin were 41% and 64%, respectively. The heterogeneity of the histopathologic pictures of LAD and LAGD, the incidence of DH, and the value of using NaCl split skin for IIF are discussed.

This study was undertaken to assess our experience with the first 50 patients who underwent CABG without cardiopulmonary bypass. In seven patients left internal mammary artery to left anterior descending artery (LIMA-LAD) grafting was performed through a short left anterior thoracotomy. In 43 other patients median sternotomy was used. Primary CABG was performed in 48 patients; there were two reoperations. Eleven patients had unstable angina. Three patients had left ventricular ejection fraction (LVEF) equal to or lower than 25%. One patient had carcinoma of the right lung coexisting with unstable angina and underwent also right lower lobectomy. In each patient the clinical course, 12-lead ECG, transthoracic echocardiography and the serum levels of creatine kinase (CPK), alanine aminotransferase (ALAT), aspartate aminotransferase (AspAT) were assessed. The need for inotropic or intraaortic balloon counterpulsation (IABP) support and blood transfusion was also recorded. There were three deaths, all in the sternotomy group (6%). A patient with systemic lupus erythemetodes (SLE) died of postoperative MI due to graft thrombosis. Another patient who was found to have porcelain aorta and had LIMA-LAD grafting as a rescue procedure died of MI with low cardiac output. The third patient with unstable angina and ejection fraction of 30% developed postoperative MI with ventricular arrhythmia. One patient with LIMA-LAD graft in whom percutaneous translaminal coronary angioplasty (PTCA) had been abandoned because of coronary spasm developed acute myocardial ischaemia 5 h postoperatively. He had a vein graft placed to LAD in cardiopulmonary bypass, his further course was uneventful. Six patients had IABP support. Nine patients needed inotropic support. Ten patients received blood transfusion. Twelve-lead ECG did not show acute ischaemia or MI, apart from the above described cases. Echocardiographic check showed improved IVS contractility in three patients and better apex motion in one case. In the other survivors the echocardiographic findings were the same as before the procedure. ALAT and AspAT serum levels were normal in all the survivors, and the CPK levels did not exceed 200 IU/ml. One patient from the mini-thoracotomy group had recurrent angina 2 months after the procedure. His left internal mammary artery (LIMA) graft was occluded; we replaced it with a vein graft. All 47 survivors remain asymptomatic, with the mean follow-up time of 6 months. Coronary surgery without cardiopulmonary bypass seems a valuable alternative for high-risk patients.

Recombinant adenoviral (Ad) vectors represent an efficient gene transfer system for targeting the cardiovascular system. Phenotypic modulation of coronary vascular cells in vivo is, however, critically dependent on the efficacy of local delivery devices. Four local drug delivery catheters were tested for intracoronary gene transfer efficiency: the Infiltrator (INF, n = 10), the Crescendo (CRE, n = 10), the Infusasleeve (SLE, n = 8), and the Remedy balloon (channel balloon [CHA], n = 8). After balloon injury of the LAD, Ad vector containing the firefly luciferase cDNA (AdCMVluc, 1.5 x 10(10) plaque-forming units) was administered at the site of injury. On day 4, tissue samples from different regions in the heart and from the liver were assayed for luciferase activity to evaluate local and systemic gene transfer. INF, CRE, and SLE catheters showed higher transduction levels of the target LAD segment than did the CHA catheter (median luciferase activity = 4.2 x 10(6), 11 x 10(6), and 1.3 x 10(6) light units [LU]/vessel versus 0.09 x 10(6) LU/vessel, respectively, p < 0.05). Luciferase activity was occasionally observed in nontarget tissues (right and left ventricular free wall, distal LAD, and liver) and was not significantly different between groups. The viral circulatory half-life was similar for the four groups (<1 min). Gene transfer efficiency was positively correlated with the degree of injury for the intralumenal catheters (CRE, SLE, and CHA) but was independent of the vessel wall injury for the intramural INF. Local drug delivery catheters enable efficient vascular gene transfer in balloon-injured coronary arteries, a prerequisite for further development of intracoronary gene therapy for restenosis.
