Influence of HLA matching in cadaveric renal transplantation: experience from one Scandiatransplant center.

The outcome of 461 prospectively HLA-A, -B and -C typed and 193 prospectively HLA-DR typed cadaveric kidney transplants in one center was followed. We found a significant beneficial effect on graft survival both of HLA-A and -B as well as of HLA-DR matching between donor and recipient, while no effects of HLA-C compatibility could be detected. The effect of HLA-DR matching was clearly more pronounced than that of HLA-A and -B matching, and a possible influence of matching for HLA-A and -B could only be seen in the HLA-DR mismatched combinations. Pretransplant blood transfusions were associated with an increased graft survival only in patients receiving HLA-DR mismatched transplants. We conclude that major emphasis should be laid on obtaining HLA-DR compatibility in clinical renal transplantation.

Elective surgery for ulcerative colitis: colectomy in 158 patients.

Chronic ulcerative colitis was treated by elective colectomy in 158 patients. Proctocolectomy and ileostomy was performed in 140 patients and colectomy and ileorectal anastomosis (CIRA) in 18 patients. The operative mortality was 2.5%, and postoperative complications, mostly infections, occurred in 38%. Within a 2-year postoperative period another 1.9% of the patients died, and late complications occurred in 18%. Colorectal carcinoma was present at the time of colectomy in 5.1% and developed some years later in another two patients primarily operated on with CIRA. Half of the cancer patients died of malignancy. Most extracolic complications, present in 25% of patients before colectomy, regressed or disappeared after operation. Half of the patients operated on with CIRA needed to have their rectum removed within a few years because of cancer or proctitis, and few of the rest had lasting relief of symptoms.

Importance of HLA-DR matching in cadaveric renal transplantation: a prospective one-center study of 170 transplants.

To investigate the influence of matching for HLA-DR antigens in renal transplantation, we assessed the outcome of 170 prospectively HLA-typed cadaveric kidney transplantations performed since 1977 in one center. We found a beneficial effect on graft survival of HLA-DR compatibility between donor and recipient (P < 0.05). A possible effect of matching for the HLA-A and B antigens could be seen only in the HLA-DR-mismatched combinations. Pretransplantation blood transfusions were associated with increased graft survival only in patients receiving HLA-DR mismatched transplants (P < 0.02). We conclude that major emphasis should be placed on obtaining HLA-DR compatibility renal transplantation. (N Engl J Med. 1980; 303:850-4).

HLA-DR typing and B cell cross-match tests in cadaveric renal transplantation.

Prospective HLA-DR typing and B cell cross-match tests were performed in 177 cadaveric transplants using a modified NIH technique, 24 selected HLA-DR typing sera and B cells separated from peripheral blood in recipients and from spleen in donors. Actuarial graft survival after one year was 60% in HLA-DR compatible transplants and 30% and 18% in transplants mis-matched for 1 and 2 HLA-DR antigens. The favorable prognostic influence of HLA-DR compatibility was observed both among HLA-A, -B compatible and incompatible transplants. Sharing of HLA-DR antigen(s) between donor and recipient was also prognostically beneficial. Standard cross-match tests were negative in all transplants. B cell cross-match tests were positive in 17 cases, and one of these transplants was very acutely rejected. Actuarial graft survival after three months was 35% in B cell cross-match positive grafts versus 53% in negative ones.

Complications after therapeutic splenectomy for hematologic disease in adults.

221 patients were treated by splenectomy for various hematologic disorders, including immunologic thrombocytopenia (80 cases), hereditary spherocytosis (15 cases), immune hemolytic anemia (25 cases), chronic lymphatic leukemia (27 cases), lymphosarcoma (27 cases), myelofibrosis (11 cases) and pancytopenia/aplastic anemia (14 cases). There were 8 postoperative deaths (3.6%), and 49 patients (22%) had postoperative complications, mainly infections and bleeding. Complications were more frequent in cases of massive splenomegaly (greater than or equal to 1 000 g) (65 cases), severe thrombocytopenia (less than 20 X 10(6)/1) (51 cases), and leukemia. Late postsplenectomy fulminant infection was seen in 8 patients (3.6%) for a mean follow up of 5.3 years. We conclude that splenectomy is sufficiently well tolerated even by severely ill patients to make it applicable as a therapeutic modality in the various hematologic disorders presently studied.
