Constrictive Pericarditis Versus Restrictive Cardiomyopathy?

Mario J. Garcia, Journal of the American College of Cardiology, Volume 67, Issue 17, 3 May 2016, Pages 2061-2076, ISSN 0735-1097, doi:10.1016/j.jacc.2016.01.076.


Friedreich’s ataxia is an autosomal recessive neurodegenerative disorder. Ventricular arrhythmias and SCD are common. Early in the course of the disease, ECG and echocardiographic findings resemble those of hypertrophic cardiomyopathy, including symmetric LV hypertrophy, abnormal myocardial relaxation, and LV outflow obstruction. Over time, the restrictive phenotype evolves into a dilated phenotype. There is no specific treatment for this condition other than standard HF drugs. Implantable cardioverter-defibrillators are used for prevention of SCD, but a survival benefit has not been demonstrated.

Horizon Pharma plc Completes Target Enrollment of 90 Patients for Phase 3 Trial of ACTIMMUNE(R) (interferon gamma-1b) for the Treatment of People With Friedreich's Ataxia

DUBLIN, IRELAND -- (Marketwired) -- 05/05/16 -- Horizon Pharma plc today announced that it has completed target enrollment of its Phase 3 study evaluating ACTIMMUNE (interferon gamma-1b) for the treatment of people with Friedreich's ataxia (FA). The study (NCT02415127) has reached its target enrollment of 90 patients at four sites in the United States, and top-line results are expected by the end of 2016.

The Safety, Tolerability and Efficacy of ACTIMMUNE Dose Escalation in Friedreich's Ataxia study ("STEADFAST") is a randomized, multi-center, double-blind, placebo-controlled study with patients randomized 1:1 to receive subcutaneous doses of either ACTIMMUNE or placebo three times a week for a total of 26 weeks. After completion of the study, patients who participated in STEADFAST will have the opportunity to transition to an open-label extension study (NCT02593773).

Patent Granted for RNA Transcription Technology

Science & Enterprise, By Alan, on May 3rd, 2016.

3 May 2016. A technology that blocks RNA molecules from activating chemicals in the body suppressing the working of genes to treat or prevent disease received a U.S. patent. The technology was licensed to RaNA Therapeutics in Cambridge, Massachusetts, co-founded by lead inventor Jeannie Lee, a professor of genetics and pathology at Mass. General and Harvard Medical School.

The first therapies under development are treatments for the rare central nervous system disorders spinal muscular atrophy and Friedreich’s ataxia, both programs are still in preclinical stages.

Dorsal root ganglia in Friedreich ataxia: satellite cell proliferation and inflammation

Arnulf H. Koeppen, R. Liane Ramirez, Alyssa B. Becker and Joseph E. Mazurkiewicz. Acta Neuropathologica Communications, Neuroscience of Disease 20164:46 DOI: 10.1186/s40478-016-0288-5

We conclude that FA differentially affects the key cellular elements of DRG, and postulate that the disease causes loss of bidirectional trophic support between satellite cells and neurons.

Friedreich ataxia (FA) is characterized on MRI bynormal morphology of the cerebellum and brainstem, withatrophy of the spinal cord . A rare involvementof dentate nuclei has been described. Cerebellaratrophy occurs late in the course of the disease.

Mitochondrial DNA damage induced autophagy, cell death, and disease

OPEN ACCESS

Several human pathologies have been associated with free radical damage and subsequent mtDNA damage and mitochondrial dysfunction. These diseases include diabetes mellitus, liver diseases (e.g. hemochromatosis), cardiovascular disease (e.g. atherosclerosis) and several neurodegenerative diseases (e.g. Alzheimer’s, Parkinson’s Disease, Friedreich’s Ataxia and Huntington’s disease). In fact, multiple studies have linked human diseases associated with oxidative stress and loss of mitochondrial function to mtDNA damage
