[Recurrence of segmental and focal glomerulosclerosis in transplanted kidneys]

The course of 16 patients with segmental and focal glomerulosclerosis (SFGS) with kidney transplantation is reported. Ten out of 16 (group I) had the diagnosis histologically confirmed in their native kidneys. In 6 (group II) the diagnosis was suggested by the early development of SFGS in the graft and was considered a recurrence of the baseline disease. The recurrence (in group I) was 40% and the main clinical parameter was proteinuria, in nephrotic level, with early development in all cases (less than 60 days). In those patients who had an early development of the baseline disease (less than 4 years) the recurrence was greater, observed in 5 out of 8 grafts with 3 grafts lost due to the recurrence of focal glomerulosclerosis. On the other hand, the patients whose baseline disease had a longer period of development presented a better course of the recurrent glomerulosclerosis and no grafts were lost in this cases. We believe that renal transplantation of a live donor must be avoided in those patients with quick developing SFGS.
