Prevalence of Fabry's disease within hemodialysis patients in Spain

Clinical Nephrology
Julio Herrera, Clara Sa Miranda


To identify patients with Fabry's disease (FD) within patients with kidney dysfunction, submitted to hemodialysis. Patients under hemodialysis were screened using a combined enzymatic α-Gal A assay and dried blood spot samples to determine GLA genotype. A total of 3,650 samples (18.5% of all patients under hemodialysis in Spain) were tested and 11 new unrelated FD patients (4 males and 7 females) were diagnosed. 66 relatives of 11 patients were tested and 23 new FD patients were identified. This study allowed the diagnosis of 34 FD patients. Among the 11 unrelated FD patients, 5 presented the same R118C mutation and one novel mutation was detected: D109G. This study reveals the need for screening for FD in all patients under hemodialysis for unknown causes and indicates that the incidence and prevalence of FD are underestimated so far.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.
