Abstract
Introduction Post hematopoietic stem cell transplant (HSCT), kidney can be subjected to injury by various causes. Of these, graft versus host disease (GvHD) affecting the kidney is an under-recognized entity with no clear guidelines on its diagnosis, clinicopathological manifestations, and outcomes. Material and Methods Out of 2,930 patients who underwent HSCT at our center between 2005 and 2020, kidney biopsy was performed in 19 allogenic and 5 autologous recipients. Results The mean age of the cohort at transplant was 33.2 ± 7 years, and 15 (62%) were males. Median time to kidney biopsy from HSCT was 14 (IQR, 9-30) months. Aplastic anemia was the most common underlying hematological disease (54.2%). All 19 allogenic recipients were classified based on clinicopathological manifestations into either thrombotic microangiopathy (TMA, 12/19 [63%]) or nephrotic syndrome (NS, 7/19 [37%]) pattern. Glomerular tuft "mesangiolysis" was the dominant pattern of injury noted in 9/12 cases of TMA pattern. There was a predominance of acute microangiopathic changes restricted primarily to the glomerular compartment. Of the 7 patients with NS pattern, membranous nephropathy was seen in 4 (57%) and minimal change disease in 3 (43%) patients. Thirty-nine percent (7/18) stained positive for C4d which was predominantly glomerular. Allogenic recipients who did not receive immunosuppression (IS) for renal disease had a lower eGFR at biopsy, a longer latency between withdrawal of GvHD prophylaxis and biopsy, and were significantly at a higher risk of kidney failure (IS: 2/11, 18.1% vs. no IS: 2/6, 33.3%, p = 0.04). "Associated extra-renal GvHD" occurred in 11/19 (57.9%) allogenic recipients. Patients with "associated extra-renal GvHD" had significantly more deaths (6/11, 60% vs. 0, p = 0.02) but comparable renal outcomes. Conclusion Renal GvHD can present with or without "associated extra-renal GvHD" after a prolonged period of withdrawal of GvHD prophylaxis, requiring careful diagnostic vigilance and consideration of IS.

Pediatric onco-nephrology: time to spread the word : Part I: early kidney involvement in children with malignancy. Pediatr Nephrol 2021; 36:2227-2255.

Abstract
Onco-nephrology has been a growing field within the adult nephrology scope of practice. Even though pediatric nephrologists have been increasingly involved in the care of children with different forms of malignancy, there has not been an emphasis on developing special expertise in this area. The fast pace of discovery in this field, including the development of new therapy protocols with their own kidney side effects and the introduction of the CD19-targeted chimeric antigen receptor T cell (CAR-T) therapy, has introduced new challenges for general pediatric nephrologists because of the unique effects of these treatments on the kidney. Moreover, with the improved outcomes in children receiving cancer therapy come an increased number of survivors at risk for chronic kidney disease related to both their cancer diagnosis and therapy. Therefore, it is time for pediatric onco-nephrology to take its spot on the expanding subspecialties map in pediatric nephrology.

Glomerular diseases associated with chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplantation: case reports. Transplant Proc 2015; 46:3616-9.

Abstract
Chronic graft-versus-host disease (cGVHD) is the major complication following allogeneic stem cell transplantation (allo-SCT). Nephrotic syndrome (NS) and other types of glomerulonephritis have been proposed to be the very rare forms of renal cGVHD. From 1991 to 2011, 253 patients underwent allo-SCT at our center. We report here 4 cases (1.6%) presenting with varieties of glomerular manifestations associated with cGVHD. The first case was typical NS. The renal pathology showed membranous nephropathy (MN). The second case was also MN, but this patient also had the pathology of focal segmental glomerulosclrosis (FSGS) and acute tubular necrosis (ATN). The third case showed lupus nephritis-like glomerular lesions with a high anti-nuclear antibody (ANA) titer. The fourth case presented with rapidly progressive glomerulonephritis (RPGN)-like symptoms. The kidney histology in this case was not available. The patient responded well to immunosuppressive therapy, but NS later recurred. Therefore, overt glomerular diseases after allo-SCT in Thai patients are not very rare. Monitoring urinalysis during withdrawal of immunosuppressive drugs and also during follow-up of patients with cGVHD may be considered.

Abstract
INTRODUCTION Allogenic hematopoietic stem cell transplant (allo-HSCT) is the treatment of choice for several hematological diseases. Although rare, patients could present nephrotic syndrome as a clinical feature of chronic graft-versus-host disease (cGVHD). The objective of our study is to screen patients with allo-HSCT to determine who developed a glomerular pathology in the context of cGVHD. PATIENTS AND METHODS We studied patients who underwent allo-HSCT treatment in our center between October 1995 and October 2012 and who developed glomerular pathology. cGVHD was defined as a pathology when it appeared after 100 d post-allo-HSCT. RESULTS Five hundred eighty-three allo-HSCT were performed. The prevalence of cGVHD of the kidney was 1.03%. All patients with cGVHD of the kidney were hosts who received peripheral blood from an identical HLA match donor. GVHD prophylaxis with calcineurin inhibitors plus methotrexate was administered in five cases, and prophylaxis with sirolimus was used in another case. cGVHD of the kidney was seen to appear after the removal of the prophylaxis for GVHD, within 33 ± 11.54 months intervals after allo-HSCT in five patients and in another patient, it appeared despite immunosuppressive therapy being administered. All patients had proteinuria, within 11.82 ± 9.03 g/d ranges. The kidney biopsies revealed membranous glomerulonephritis (four patients), focal segmental glomerulonephritis (one patient) and lupus nephropathy class III (one patient). It seems, immunosuppressive therapy achieved complete remission, within the first year of treatment in four patients. Although in three of them, the proteinuria recurred when we tried to remove the therapy; two patients have recently started treatment, being in partial remission now. CONCLUSIONS cGVHD of the kidney is a rare complication after allo-HSCT, related with the removal of the immunosuppression. Monitoring proteinuria in these patients may be useful. In our patients, a complete remission was achieved; although the removal of the immunosuppression may lead to the appearance of outbreaks. We must reconsider the treatment of glomerular pathology secondary to cGVHD.
