| Abstract | AIM: The ever-growing number and increasing survival of haematopoietic stem cell transplantation (HSCT) allow better recognition of its associated renal injuries. We aimed to study the clinicopathologic features of renal biopsies after HSCT by reviewing 13 percutaneous renal biopsies in our institute (Queen Mary Hospital). METHODS: A retrospective clinicopathologic study of all renal biopsies archived to the Department of Pathology, Queen Mary Hospital during the period January 1999 to December 2006 was performed. Biopsies from patients with HSCT were selected. Clinical data on presentation and follow up were retrieved from hospital records and physicians. RESULTS: In the 8-year period, a total of 2233 native renal biopsies were archived. Thirteen renal biopsies were selected from 12 patients with HSCT (11 allogeneic, one autologous). All but one patient were male. The age at renal biopsy ranged from 7 to 63 years (median: 32 years). The median interval of renal biopsy after HSCT was 24 months (range 1-134 months). Evidence of graft-versus-host disease was found in nine patients. The most common presentation was significant proteinuria (10 cases) and renal impairment (eight cases). The predominant histological changes were membranous glomerulonephritis (n = 4) and thrombotic microangiopathy (n = 4). One case of focal segmental glomerulosclerosis, IgA nephropathy, minimal change disease, acute tubular necrosis and hypertensive nephrosclerosis were also recorded. Four of our patients died at 0-11 months after renal biopsy. Of the remaining eight patients with a mean follow up of 43.6 months (range, 10-98 months), chronic renal impairment were found in three (37.5%) patients and significant proteinuria also persisted in three. One patient had cytogenetic evidence of relapse of underlying haematological malignancy after HSCT. CONCLUSION: Among the various renal lesions after HSCT, membranous glomerulonephritis and thrombotic microangiopathy were the most common. Mechanisms of renal injury varied from graft-versus-host disease-associated immune complex deposition to non-immune complex injury on endothelial cells, glomerular epithelial cells and tubular epithelium. Pathologists and clinicians should attend to the histological and temporal heterogeneity of renal injury when managing patients after HSCT. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
