Unmasking and successful management of light chain deposition disease of kidney in pregnancy: a complex case, mirroring the complex needs of pregnancy with kidney disease in India.

Pregnancy offers a precious window of opportunity to diagnose previously undetected or new onset kidney diseases in emerging countries like India, where access to medical, educational and health care facilities are not equitably distributed across varied sections of society. We report a case of a 33 year-old primi gravida who had a successful pregnancy following what was initially considered to represent preeclampsia at 38 weeks of gestation, in whom a subsequent kidney biopsy for persistence of pregnancy-related acute kidney injury (Pr-AKI) revealed light chain deposition disease (LCDD). The etiological evaluation of LCDD led to the detection of an underlying plasma cell dyscrasia which was treated effectively with chemotherapy and autologous stem cell transplant. In this report, we explore the hitherto uncharted pathophysiological relationship between LCDD and pregnancy-related kidney injury by transmission electron microscopic (TEM) studies of endothelial injury in this setting, and underscore the benefits of medical care in a multidisciplinary environment which yielded gratifying results in preservation of maternal kidney health and fetal outcome.
