Pyoderma gangrenosum and extensive caval thrombosis associated with the antiphospholipid syndrome--a case report.

Pyoderma gangrenosum is a rare cutaneous disorder frequently associated with systemic diseases. The authors report the case of a 28-year-old man with pyoderma gangrenosum and inferior cava vein syndrome due to thrombosis. The search for pyoderma gangrenosum-associated conditions (gastrointestinal, rheumatic, neoplasic, and infectious diseases) was negative. A prolonged partial thromboplastin time and a positive test for circulating anticardiolipin antibodies strongly suggested the diagnosis of the antiphospholipid syndrome. There are reports of at least three other cases of pyoderma gangrenosum associated with the antiphospholipid syndrome. This clinical case adds further evidence to the possible link between these disorders and warrants a search for anticardiolipin antibodies in patients with pyoderma gangrenosum.

[Immunosuppression and blood transfusions in patients with a kidney transplant]. / Inmunosupresión y transfusiones sanguíneas en pacientes con trasplante renal.

94 patients with renal allograft from a living related donor were studied in three different groups: 1 Patients with identical histocompatibility (n-32), treated with prednisone (PDN) and azathioprine (Aza); 2 Haploidentical patients (34) who received PDN, Aza and cyclosporine (CsA); 3 Haploidentical patients (28) who previous to the transplantation received specific donor blood transfusions and Aza/PDN after the transplantation. The survival for the patient and the graft after five years was 100% and 96% in group 1; 97% y 89% in group 2 and 82% and 72% in group 3. Five patients in group 1 received CsA also. There was no mortality in group 1, while there were one death in group 2 and two more in group 3. There was no significant difference between CsA and Blood transfusions in the patients and grafts survival.
