Two newly identified variants of the known pharmaceutical agent chloroindazole showed significant anti-inflammatory and neuroprotective benefits in a mouse model of multiple sclerosis, a new study shows. Multiple sclerosis is an autoimmune, demyelinating disease of the central nervous system with no known cause or cure. Patients with MS characteristically show loss of the myelin sheath, a protective coat in nerve cells that helps increase cell-to-cell signaling. Several studies have suggested that estrogens — a type of hormone — are beneficial to the functioning of the central nervous system, and help regulate the immune system. Thus, they are attractive candidates for the treatment of MS. However, despite their potential to treat MS, estrogen-based therapies can have several undesirable side effects, such as feminizing male recipients and increasing the risk of developing breast and endometrial cancers in females. Interestingly, estrogens work by binding and activating two different types of receptors: the estrogen receptor (ER)α and ERβ. The cancer-inducing effects of estrogens are mediated mainly through estrogen receptor ERα. Hence, therapies that specifically target ERβ can bypass these deleterious effects. Chloroindazole (IndCl), a pharmaceutical agent, has up to 100-fold relative binding affinity for ERβ over ERα. IndCl has been shown previously to have beneficial effects on modulating the immune system and the central nervous system, and inducing myelination of nerve cells in mouse models of MS. Furthermore, IndCl and other ERβ-activating agents directly support the growth, differentiation (maturation), and overall myelination activity of oligodendrocytes, which are the nerve cells that produce the myelin sheath. Therefore, in order to optimize the benefits of IndCl, researchers developed and screened seven novel IndCl analogues for their ability to promote oligodendrocyte survival, growth, and differentiation. These analogues have a molecular structure closely similar to that of IndCl, but interact with estrogen receptors in subtly different ways. Among these seven compounds, researchers found two analogues — IndCl-o-chloro and IndCl-o-methyl — that stimulated growth and differentiation similar to the original IndCl. Next, researchers evaluated the benefits of these compounds in a mouse model of MS — the experimental autoimmune encephalomyelitis (EAE) mouse model — to determine whether they could alter the disease course, white matter pathology (level of demyelination), and inflammation. Results indicated that both compounds “ameliorated disease severity, increased mature OLs [oligodendrocytes], and improved overall myelination in the corpus callosum and white matter tracts of the spinal cord,” researchers wrote. Corpus callosum is a thick band of nerves that connect the left and right side of the brain. White matter tracts connect the cortex (the largest part of the brain) with other areas in the central nervous system. These beneficial effects were accompanied by a reduced production of the toxic, inflammatory molecules interferon-γ and CXCL10. Additionally, IndCl-o-methyl also reduced the levels of peripheral interleukin (IL)-17, a molecule that strongly induces inflammation. Furthermore, IndCl and both analogues upregulated the expression of a compound called CXCL1, which is associated with increased production of oligodendrocytes. Not only were these two newly identified compounds equivalent to IndCl, but the two analogues performed better in reducing disability and encouraging remyelination than the original compound, and without any obvious side effects. “The o-Methyl and o-Chloro IndCl analogues represent a class of ERβ ligands that offer significant remyelination and neuroprotection, as well as modulation of the immune system; hence, they appear appropriate to consider further for therapeutic development in multiple sclerosis and other demyelinating diseases,” the researchers concluded. “We believe we created a drug that does two things really well, modulating inflammation and allowing axon remyelination. No other drug on the market can do these two things simultaneously,” Seema K. Tiwari-Woodruff, said in a press release written by Stacy Kish. Tiwari-Woodruff is the study's lead author. “The most amazing part of the study is that these new analogues of a known estrogen modulator, chloroindazole, are superior in treating mouse model of multiple sclerosis,” she added. The team has patented the analogues, and hopes to begin further pharmacological and toxicity studies soon.

The U.S. Food and Drug Administration (FDA) has warned against the use of plasma transfusions from young donors to alleviate or treat the symptoms of multiple sclerosis or other diseases, noting such transfusions have no proven clinical benefit and carry known health risks associated with their use. Plasma is the liquid component of blood, containing proteins that help in clotting, and can be used to treat bleeding disorders and cases of trauma. But its use in transfusions as a means of treating conditions ranging from multiple sclerosis, dementia, Alzheimer’s, Parkinson’s, heart disease and post-traumatic stress disorder are of concern, the FDA said in issuing its statement of Feb 19. "We have significant public health concerns about the promotion and use of plasma for these purposes," the FDA statement reads. "[W]e’re alerting consumers and health care providers that treatments using plasma from young donors have not gone through the rigorous testing … [necessary] to confirm the therapeutic benefit of a product and to ensure its safety." Scott Gottlieb, the FDA's commissioner, and Peter Marks, director of its Center for Biologics Evaluation and Research, jointly issued the statement cautioning healthcare providers and the public that plasma infusions — being done at "a growing number of clinics" in several U.S. states — are not an FDA-approved or recognized treatment for aging, memory loss, multiple sclerosis, or other diseases. FDA-approved treatments largely come through clinical trials overseen by researchers and independent boards, and performed under an investigational new drug (IND) application that helps to ensure patient safety. “Our concerns regarding treatments using plasma from young donors are heightened by the fact that there is no compelling clinical evidence on its efficacy, nor is there information on appropriate dosing for treatment of the conditions for which these products are being advertised,” the statement notes. According to the FDA, large volumes of plasma might be also be needed for such transfusions and that volume can pose significant risks, including allergic reactions, infections, and heart and respiratory problems. The agency also expressed concern that such transfusions could discourage patients from taking medications or other treatments known to be safe and effective for their condition. According to the agency, some "establishments" across the country are recommending young donor plasma infusions and "touting" them "as cures and remedies," while sometimes "charging thousands of dollars." The FDA advises patients to consult with their treating physician before opting for any treatment to confirm that it is approved for use, meaning its safety and effectiveness have been demonstrated. “Simply put, we’re concerned that some patients are being preyed upon by unscrupulous actors touting treatments of plasma from young donors,” the FDA statement reads. It also asks that patients who have undergone a plasma transfusion report any ill effects to its MedWatch program, which tracks adverse events related to treatments.

Vitamins B12 and B9 (folic acid) supplements can lower levels of homocysteine (a common amino acid), improve anemia status, and boost self-reported physical health in patients with multiple sclerosis, according to new research. The study suggests a potential role for these two vitamins in improving the quality of life of MS patients. Despite treatment, MS patients often experience symptoms that interfere with their daily lives. Many patients have turned to dietary supplements with the hope they would reduce the severity of their symptoms. There is substantial literature suggesting the benefits of various supplements for MS, including vitamin B12 and folic acid. Homocysteine, of which high levels are associated with heart disease and detrimental effects in the nervous system, can be more prevalent in MS patients compared to healthy individuals. That suggests homocysteine is "one of the causative factors in the pathogenesis [development] of MS," researchers wrote. Lack of vitamin B12 — naturally found in meat, fish, poultry, eggs, and dairy products — can lead to a disruption in myelination, the process of forming a protective myelin coat around nerve cells. The loss of myelin is a hallmark of MS. A lack of folic acid, together with too little vitamin B12, has been linked to neurological symptom onset in MS patients. Meanwhile, vitamin B12 and folic acid supplements have shown promising results among these patients. In addition, MS patients are known to have an increased risk for the development of megaloblastic anemia — a condition in which the bone marrow produces unusually large, immature red blood cells referred to as megaloblasts. The most common causes of megaloblastic anemia are a deficiency of either vitamin B12 or folic acid. Based on these observations, researchers from Urmia University of Medical Sciences and Kermanshah University of Medical Sciences, in Iran, studied the effects of vitamin B12 and folic acid supplements in  relapsing-remitting multiple sclerosis (RRMS) patients. The team looked specifically at serum homocysteine levels, anemia status, and quality of life. This double-blinded clinical trial (IRCT2015100313678N7) enrolled 50 RRMS patients (age 20-40 years), who were divided into two groups: the vitamin group, which received three doses of 1 mg vitamin B12 injection (spaced a month apart) plus 5 mg folic acid tablets daily; and the placebo group, which received neutral saline injections. All participants completed two quality-of-life questionnaires, one geared toward physical health and the other toward mental health, at the start and end of the study. Blood samples were collected from all participants, and blood pressure readings were taken. Results showed a drop in average homocysteine blood serum levels in the vitamin group, which may be indicative of an improvement in nervous system health. Researchers also observed a decrease in mean corpuscular volume (MCV) in the vitamin group, which is indicative of improved anemia status. At the end of the study the vitamin group showed improvements in both physical and mental fields in the quality-of-life questionnaires. However, RRMS patients in the control group (without vitamin supplements) also had an increase in the quality-of-life questionnaire for mental health, obscuring any conclusions on the effect of vitamin supplements in MS patients’ mental health. “Results of the present study have shown that homocysteine levels, anemia status, and eventually the quality of life of patients with MS can be significantly improved by administration of 1 mg of vitamin B12 monthly and adding rich-food sources of folic acid on their diet,” the researchers wrote. The team nonetheless emphasizes that "further studies in the field of MS dietary patterns must be conducted."
