Acute rejection

Acute cellular rejection.

The incidence of acute rejection of the kidney allograft in the world has been around 15% during the period between 2001 and 2003. It is clinically defined as an elevation in the level of serum creatinine by more than 0.3 mg/dL and is diagnosed by kidney biopsy. On pathologic examination, the interstitium of the allograft is diffusely edematous and infiltrated by CD4 and CD8 lymphocytes. Tubuli...

Acute Rejection Following Cardiac Transplantation

Nine patients have undergone cardiac transplantation at Stanford University Hospital. Three of these showed no clinical evidence of rejection and had essentially normal physical and phonocardiographic findings. There were eight distinct early rejection episodes in the other six patients. Early rejection was accompanied by decreasing QRS voltage, an early diastolic gallop, and frequently a right...

Diagnosis of acute rejection with cardiac ultrasound.

ACUTE rejection (AR) following heart transplantation (HTX) is characterized histologically by patchy or diffuse cellular infiltrates, interstitial oedema, and, if AR is more severe, by myocyte necrosis and hemorrhage. Main criterion for the usefulness of any diagnostic tool is its capability to rapidly and reliably detect AR at the latest stage when intensified immunosuppression is required. Fo...
