Recurrence of Wegener's granulomatosis following renal transplantation.

A 43-yr-old man with a 19-yr history of Wegener's granulomatosis presented with recurrent haematuria, pulmonary infiltrate, cutaneous vasculitis, nasal mucosal involvement and elevation of ANCA levels, 2 yr following successful cadaveric renal transplantation, despite continued immunosuppressive therapy with cyclosporine, azathioprine and prednisone. Re-introduction of cyclophosphamide therapy resulted in prompt resolution of clinical and laboratory abnormalities. The superiority of cyclophosphamide over cyclosporine for maintaining suppression of Wegener's granulomatosis is substantiated in a critical review of the literature.

HIV infection in kidney transplant recipients.

Four HIV-infected patients received cadaver kidney transplants. A fifth kidney transplant patient acquired infection through a blood transfusion. The course and prognosis of these patients with HIV infection are described and a review of the literature is presented.

Xanthogranulomatous pyelonephritis in a renal allograft.

We report a case of xanthogranulomatous pyelonephritis in a cadaver kidney allograft. The patient had diabetic glomerulosclerosis. The predisposing factors that led to this condition included hyperglycemia, a previous rejection reaction and Escherichia coli urinary infection. Persistent fever, pyuria, bacilluria and a nonfunctioning allograft resulted in allograft nephrectomy. The diagnosis was made on histological examination. Diagnostic criteria for xanthogranulomatous pyelonephritis in the allografted kidney are similar to those in the native kidney.

The role of anaerobic bacteria in the pathogenesis of urinary tract infections.

Because of the rarity of anaerobic infections of the urinary tract and the difficulty of establishing these organisms as pathogens, anaerobic culture is not included as part of routine urine bacteriological examination. Pyuria was found during examination of a 41-year-old man with a chronic renal allograft rejection reaction. Aerobic urine cultures failed to yield any pathogens. Urine cytology demonstrated intracellular organisms that proved to be Fusobacterium nucleatum on anaerobic culture. The serotypically identical organism was isolated from a needle biopsy specimen of the renal allograft. In the presence of pyuria the finding of micro-organisms in the urine sediment that fail to grow on routine aerobic cultures should lead to examination for anaerobic bacterial infection of the urinary tract.

Duration of hepatitis B surface antigenemia (HBs Ag) in hemodialysis patients.

Follow-up studies were done on 231 hemodialysis patients during a period of from one to 48 months to determine the natural history of hepatitis B surface antigenemia (HBs Ag). Of those studied, 113 (49%) exhibited HBs Ag. The probability of remaining HBs Ag positive over the mean follow-up period of 14.4 months was 62%. All of the 38 patients whose HBs Ag reverted to negative did so within ten months. Those patients whose HBs Ag reverted to negative had SGOT levels that were less frequently elevated than the patients with persistent antigenemia. Of hemodialysis patients with HBs Ag, 60% showed e antigen (HBe Ag).

Air embolization during the machine preservation of kidney.

Air embolization during machine preservation of kidneys for transplantation occurred in seven of 218 kidneys. In three it occured during transportation on a portable machine. On arrival they had warmed up and were discarded. In four kidneys air embolization occured in the laboratory and was detected immediately. Upon re-establishment of perfusion, there was a sharply lower flow and a higher diastolic pressure. Within 30 to 120 minutes the flow reached the pre-embolization rate and the diastolic pressure stabilized at a slightly higher level than before embolization. One recipient died 2 months after transplantation due to infection, and one kidney was removed because of rejection after 32 days. Two patients receiving the mates to the above kidneys were discharged with excellent kidney function. If the exact time of air embolization cannot be determined, it is prudent to discard the kidneys. This indicates the importance of continuous supervision during the perfusion. When air embolization occurs in the laboratory and is detected immediately, the kidney should be evaluated carefully. If, after correction of the defect, the perfusion and diastolic pressure reach the neighborhood of pre-embolization levels within 30 to 120 minutes with no patchy discoloration, the kidney is suitable for transportation. Discarding kidneys with air emboli without proper evaluation is not justifiable.

Fibrinous uremic pleuritis: a surgical entity.

Fibrosing uremic pleuritis is a newly recognized late complication of uremia. Extreme incarceration of the lining and chest wall can occur with disabling restriction of pulmonary function. Decortication of the chest wall and the lung can be carried out safely with minimal bleeding and restoration of pulmonary function.
