Longitudinal data collection in pediatric and adult patients with 5q spinal muscular atrophy in Latin America: LATAM RegistrAME study - a clinical registry study protocol.

Spinal muscular atrophy is a rare hereditary neurodegenerative disease characterized by progressive motor neuron loss. The most common form of SMA is linked to 5q (5q-SMA) and is classified into subtypes according to the age of onset and maximum motor function achieved. The severity ranges from progressive infantile paralysis and premature death (type 1) to limited motor neuron loss in adults (type 4).

ACE activity is modulated by the enzyme α-galactosidase A.

Fabry disease is a multisystem X-linked disorder resulting from α-galactosidase A (α-GalA) gene mutations leading to the accumulation of globotriaosylceramide mainly in endothelium compromising heart, kidney, and brain. In Fabry patients, progressive renal failure is frequently treated with angiotensin I-converting enzyme (ACE) inhibitors. We were interested in the possible interactions between ACE inhibitors therapy and the only causative therapy for Fabry disease, the enzyme replacement therapy (ERT) using recombinant human α-GalA (rhα-GalA).

Long term treatment with ACE inhibitor enalapril decreases body weight gain and increases life span in rats.

Renin-angiotensin system is involved in homeostasis processes linked to renal and cardiovascular system and recently has been linked to metabolic syndrome. We analyzed the influence of long term angiotensin I converting enzyme (ACE) inhibitor enalapril treatment in normotensive adult Wistar rats fed with standard or palatable hyperlipidic diets. Our results show that long term enalapril treatment decreases absolute food intake, serum leptin concentration and body weight gain.
