Common Antibiotic Might Help Treat Myotonic Dystrophy Type 1 – Promising Therapy

In a study published in December 2015 in a peer review journal researchers from Japan and Poland found that a commonly used antibiotic might assist in the treatment of Myotonic Dystrophy. This is a sort of stunning discovery as there is no treatment identified to treat the disease. Treatment now consists of reducing symptoms.

The researchers first began by screening antibiotics. In a screen of 20 antibiotics 2-3 were found to have some potential with the disease.When screening the drugs they first used mice cells and lab equipment to find the most promising compounds (drugs). . Erythromyicin was found to have the highest attraction to the RNA CUG expansion (The opposite of CTG repeats in the DNA) Erythromycin was the drug that the researchers chose to study.

The researchers were looking at drug re-positioning or “Off label Use” of the some drugs. That is that were looking for already approved safe drugs that might, as a side effect,  help to treat myotonic dystrophy. Erythromycin seemed to fit the bill.

This drug has been used in the past on patients with myotonic dystrophy to help improve stomach issues. Erythromycin is also reported to stimulate gastrointestinal motor activity via effects on motilin receptors. In a previous study, the erythromycin ethylsuccinate ester was tested to improve gastric emptying in DM1 patients when administered at a dose of 50–200 mg/day for 4 weeks.36 While no significant change in the gastric emptying rate was observed in the study, some gastrointestinal symptoms, including nausea, ability to eat, and diarrhea, were attenuated in DM1 patients. Although the dosage of erythromycin was relatively low and skeletal muscle symptoms were not evaluated, such improvements might have occurred through neutralization of toxic RNA.

Well the results were Stunning. The drug Erythromycin reduced the Foci Formation in the cells of mice. The foci are thought to be where the RNA’s that are defective are binding with needed proteins causes the cells to “Clog” and reduce there critical functions. So the bad foci’s are reduced. The drug also reduces mi-ssplicing events or errors in the cells producing the right components.

Importantly the oral administration of This drug (the easiest way to take it) in Mice that had myotonic dystrophy showed the reversal of this mis-splicing events. It also showed improvement of the myotonia that the mice had with no toxic effects! “Long term oral administration of erythomycin at the dose used in humans also improved improved the splicing abnormality  in DM1 model mice”

Now the limitations. This drug erythromycin affects the heart. That’s bad. Myotonic Dystrophy patients, many of them have heart problems. Some people with this disease just die of sudden cardiac failure. So don’t do anything without discussing this with your doctor and cardiologist!!!

The research team in Japan is planning human studies. We will post information when this becomes available. Most likely the studies will be based in Osaka Japan.

As their last statement the researchers said ” Interpretation:  Oral erythromycin treatment, which has been widely used in humans with excellent tolerability, may be a promising therapy for DM1 (myotonic dystrophy type 1)

  1. Who is the leading authority in the USA on myotonic dystrophy? My friend has a three year old granddaughter with MD. Thank you. Fred Whitehouse

  2. Hi I have myatonic dystrophy and I hate that I can’t do a lot of things for myself. It’s terrible, I feel like a burden to my family. I just try to forget about it but it’s terriable when we go out for dinner and I need help always getting out of my chair. Please give me any easy ways to help me if you can. Anyway thanks for for reading this message.

    • I have Myotonic Muscular Dystophy. You are not alone, I have the same problem on sofas or chairs without armrest, and even those are a problem. What I’ve found what helps is to put a cushion or rolled up jacket on your chair. Going out I just carry a light jacket and put it on a chair. Sitting up higher might help.

  3. I was I was diagnosed with Myotonic Dystrophy approximately 6 months ago and have days of extreme fatigue, muscle weakness, shortness of breath and fast heart rate etc..
    I have days where simply chewing food fatigues my jaw muscles which is very discouraging.

  4. Please send me any new information on any news regarding a cure or treatment for myatonic dtstrophy . I have been waiting , praying and believing for this to happen for 10 years, thank you!
