Conversion from cyclosporine to azathioprine following heart transplantation.

Eleven patients receiving cyclosporine were converted to azathioprine immunosuppression because of persistent creatinine elevation greater than 2 mg/dl 6 months or more following heart transplantation. During conversion, the maintenance steroid dose was doubled for 3 months then tapered to the preconversion dose. Pretransplant renal function in these converted patients was similar to that in a group of azathioprine patients and a group of nonconverted cyclosporine patients.

Results of radionuclide assessment of cardiac function following transplantation of the heart.

Radionuclide assessment of ejection fraction was determined early and late postoperatively following cardiac transplantation in 16 patients. In 11 patients, ejection fraction was determined within 48 hours of an endocardial biopsy. There was no relationship between the severity of histologically evident rejection and the ejection fraction (Pearson correlation coefficient [r] = -0.

Gallium-67 scanning in Sjögren's syndrome: concise communication.

We performed gallium-67 scans in 12 patients with primary or secondary Sjögren's syndrome (SS). Salivary-gland uptake of gallium-67 was noted in four of five patients with primary SS. Pulmonary uptake was observed in ten of 12 patients.
