GM1 ganglioside in Parkinson's disease: Results of a five year open study

Abstract

Previous work demonstrated that short-term (i.e., 16 weeks) use of GM1 ganglioside resulted in significant symptom reduction in Parkinson's disease (PD) patients. As GM1 use may have long-term benefit for PD patients, the present study was conducted to evaluate the long-term safety and efficacy of GM1 in PD patients. Twenty-six patients who concluded a previous randomized double blind placebo controlled trial of GM1 volunteered for this open-extension study. At the end of 5 years of GM1 use, patients generally had lower Unified Parkinson's Disease Rating Scale (UPDRS) motor scores (assessed during a practically defined "off" period) than at baseline prior to randomization into the original study. A similar result was found for UPDRS Activities of Daily Living scores. Performance of timed motor tests also remained mostly stable over the 5 year observation period. No consistent clinically significant changes in blood chemistry, hematologic indices or urine chemistry were noted over the course of this study. These results suggest that long-term GM1 use by PD patients is safe and may provide some clinical benefit for PD patients. Additional study is required to more completely assess the degree to which GM1 treatment may be a sympt...Continue Reading

COVID-19

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
