The Fabry nephropathy: new insight in diagnosis, monitoring and treatment

Abstract

Fabry disease is a rare inborn error of the enzyme α-galactosidase (Α-Gal) and results in lysosomal substrate accumulation in tissues with a wide range of clinical presentations. The disease has attracted a lot of interest over the last years and several issues has been discovered up to now leading to increasing knowledge and awareness of the disease. However, several aspects are still unclear and under investigation. Thus, the new challenges that physicians encounter are the discovering of the pathogenic mechanisms, the neutralising antibodies to ERT, the long-term efficacy of therapies.

In this article, we summarise and review the latest developments in the science community regarding diagnosis, management and monitoring of Fabry disease concerning in particular its physiopathology, novel biomarkers, antibodies development and novel treatment options.

Ultrasonography in chronic lithium nephropathy: a case report

Abstract

Lithium has always been used as a first-choice therapy in bipolar disorders. However, its therapeutic index is restricted by placing patients at risk of potential nephrotoxic effects ranging from polyuria, to Insipid Nephrogenic Diabetes, to chronic kidney disease with a slow reduction of renal function over time. The Nephrologist has the role to diagnose chronic lithium nephropathy, monitoring its evolution and optimizing the management of risks associated with the treatment. In fact, the main objective, to be shared with the psychiatrist, is to encourage the maintenance of therapy even in the presence of nephropathy. Renal ultrasound, a safe, repeatable and low-cost technique, is essential to pursue this goal as it not only confirms the diagnosis of chronic lithium nephropathy hypothesized on the basis of the history and clinical picture, but is also helpful in monitoring its evolution. In this paper, we report a case of chronic lithium nephropathy in order to analyze the etiopathogenesis of renal damage, the clinical-laboratory and histological picture and, in particular, the fundamental role of ultrasound imaging.
