: Renal injury associated with hematopoietic stem cell transplant (HSCT) may be related to a combination of factors. Chronic graft-versus-host disease (cGVHD) is the most common complication of allogeneic HSCT. Although the kidneys are not considered the primary target organs for GVHD, chronic impairment of renal function may occur in 20% to 60% of HSCT patients. Membranous glomerulonephritis (MG) is the most frequent renal complication observed in patients who develop nephrotic syndrome after allogeneic HSCT. In this setting, the pathogenesis of MG is not clearly understood and the most appropriate treatment approach has not been established. In order to summarize the current knowledge on this issue, a review of the pertinent literature has been performed. The available data on MG diagnosed in patients submitted to allogeneic HSCT were identified using the MEDLINE database (last accessed: Jan 30, 2012). Fifty-nine patients with allogeneic HSCT-related MG with a median age of 43 years were identified. MG occurred at a median time of 17 months after allogeneic HSCT. A history of acute or concomitant clinically apparent cGVHD was present in 69% and 31% of cases, respectively. cGVHD, nonmyeloablative conditioning regimens, immunosuppression withdrawal, and the use of peripheral blood stem cell grafts were identified as risk factors. Among the 53 patients with available outcome data, complete remission, partial response, and inefficacy of treatment were recorded in 65%, 22% and 13% of cases, respectively. MG after allogeneic HSCT seems to be etiologically related to subclinical or overt cGVHD, which flares up after discontinuation of immunosuppression. The available measures can induce sustained long-term remission in about two-thirds of affected patients.

Abstract
: Renal injury associated with hematopoietic stem cell transplant (HSCT) may be related to a combination of factors. Chronic graft-versus-host disease (cGVHD) is the most common complication of allogeneic HSCT. Although the kidneys are not considered the primary target organs for GVHD, chronic impairment of renal function may occur in 20% to 60% of HSCT patients. Membranous glomerulonephritis (MG) is the most frequent renal complication observed in patients who develop nephrotic syndrome after allogeneic HSCT. In this setting, the pathogenesis of MG is not clearly understood and the most appropriate treatment approach has not been established. In order to summarize the current knowledge on this issue, a review of the pertinent literature has been performed. The available data on MG diagnosed in patients submitted to allogeneic HSCT were identified using the MEDLINE database (last accessed: Jan 30, 2012). Fifty-nine patients with allogeneic HSCT-related MG with a median age of 43 years were identified. MG occurred at a median time of 17 months after allogeneic HSCT. A history of acute or concomitant clinically apparent cGVHD was present in 69% and 31% of cases, respectively. cGVHD, nonmyeloablative conditioning regimens, immunosuppression withdrawal, and the use of peripheral blood stem cell grafts were identified as risk factors. Among the 53 patients with available outcome data, complete remission, partial response, and inefficacy of treatment were recorded in 65%, 22% and 13% of cases, respectively. MG after allogeneic HSCT seems to be etiologically related to subclinical or overt cGVHD, which flares up after discontinuation of immunosuppression. The available measures can induce sustained long-term remission in about two-thirds of affected patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
