Graft rupture after high-dose intravenous immunoglobulin therapy in a renal transplant patient.

Cases of life-threatening thromboses in pulmonary, coronary, cerebral and peripheral vessels are associated with high-dose intravenous immunoglobulin (IVIg) therapy that is generally considered safe. We experienced a patient with a renal graft rupture that developed after high-dose IVIg was administered for desensitization. A needle biopsy performed 4 days prior to the rupture revealed the presence of glomerular thrombosis and mesangiolysis. The ruptured nephrectomy specimen contained renal infarction around the haemorrhagic segment and arterial wall thickening with intimal fibrosis. This might have contributed to rupturing associated with small arterial and glomerular arteriolar thrombi. This is the first case of a graft rupture as a complication of high-dose IVIg we have encountered.
