Ischemic stroke due to hypoperfusion in a patient with a previously unrecognized Danon disease.

Danon disease, an X-linked multisystemic disorder, is due to deficiency of Lysosome-Associated Membrane Protein 2 (LAMP2). It is usually characterized by hypertrophic cardiomyopathy, mental retardation and skeletal myopathy, sometimes also with atypical features. A 20-year-old man with cognitive impairment was admitted to the Emergency Room because of a sudden chest pain.

Association of donor-specific microchimerism with graft dysfunction in kidney transplant patients.

The biological significance of donor-specific microchimerism (DSM) in solid organ transplantation is unresolved. It has been reported both as a favourable feature, which may facilitate induction and maintenance of tolerance, and as a sign of graft-vs-host disease. Here, we applied a quantitative real-time PCR assay (qRT-PCR) to a selected series of kidney transplant recipients to measure the level of microchimerism in relation to allograft function and survival.

[Living donor kidney transplant: the crossover modality].

Living donor kidney transplantation (LKD) has to be considered the best transplant choice for ESRD patients in terms of organ quality and survival. ABO incompatibility and positive cross-match frequently impede LKD. Recently, options based on stronger immunosuppression, apheresis techniques and Ig administration have been proposed to overcome the biological barriers.

Living kidney transplantation: evaluation of renal function and morphology of potential donors.

The evaluation of potential living kidney donors requires an accurate study of renal function and morphology. The gold standard to assess renal function is the measurement of glomerular filtration rate (GFR). However, GFR is often estimated from serum creatinine (SCr), cystatin C (SCys), or creatinine clearance (CCr).
