Menstrual Issues Women Myotonic Dystrophy

There has been a lot of information about this but nothing published. Here are a few posts on the subject, from an older discussion board. Please add comments to add to the body of knowledge.

This question was submitted to an older discussion board and the family would appreciate any information that is available:

My daughter has myotonic dystrophy and in the past nine months started to have terrible problems with her periods. For three weeks out of four she is in consistent pain and is very poorly with them. Do you think that this could be connected with MD being soft muscle or are we looking at something else as well. Any suggestions for treatment or medications. Any doctors that can help?

General Information on DM1

Featured

This is a diagram or the major effects of Myotonic Dystrophy on the Human. Click to enlarge

The Blog. You’ve reached this site as you may be the one of nearly one million people affected by Myotonic Dystrophy  Worldwide. This site aggregates and publishes all information on Myotonic Dystrophy Myotonic Dystrophy is a disease that is genetically based and inherited from one generation to the next. One out of two children of a person  with myotonic dystrophy will most likely have  the disease. Unlike most diseases, the symptoms that a person with this disease varies from person to person. Some people are just mildly affected others are severely affected. This makes it hard to tell you exactly how the disease will affect a particular person.

Four treatments that have potential have now surfaced about Myotonic Dystrophy. These are three approved Drugs by FDA and “off label use” may assist some people with DM1. (As always check with your Doctor) . The other is a drug that is not FDA approved in the USA for human use. Three off label uses have showed promise in mice studies but as yet there is no human data… In January of 2017 Ionis Pharmaceuticals stopped the trials of its DMPK-2.5Rx drug as it failed to show promise in the human trials. There are a few drugs that are in development to treat myotonic dystrophy with various approaches such as small molecules but not available now. There have been some studies in mice or human cells of currently approved FDA drugs but no human studies. A few are listed below.

===> Furamidine Study in mice and cells with Erythromycin
====>Colchicine (Colcrys, Mitigare), Fall 2019 a study in mice and human cells

====> Erythromycin study in cells and mice successfully pushes back disease in Mice
====> Actinomycin D study in cells and mice successfully pushes back disease in Mice
====> Phenylbutazone Ketoprofen  Study in cells and mice pushes back disease in mice. NSAID type drugs. Ketoprofen would be strongly preferred. However, ketoprofen is no longer manufactured.

NOTE: These potential treatments are just that potential. NO studies in humans have been completed and reported. However, more and more information is available and here at this site you will find all that is published. You and your doctor should discuss these if you feel it warranted.

Myotonic dystrophy is a rare disease with an incidence of about one in 8000 in European and North American Populations. The incidence in Japan is approximately 1 in 20,000. In Africa and China the incidence is much lower.  The incidence of the congenital form of myotonic dystrophy  is much lower with an incidence of 1/100,000. A more recent study by Campbell in Canada put the incidence of the congenital form at 1/47,000 That means that most doctors will not have a patient with the disease in their practice. Thus, many people are turning to organizations like the Myotonic Dystrophy Foundation for help and assistance.

Women and Myotonic Dystrophy

Women are uniquely affected by Myotonic Dystrophy. The congenital form of the disease is almost exclusively passed on by the mother. With the birth of a congenital infant the mother will need to care for the infant while she herself is affected with a slowly progressive disease. This disease manifests itself very insidiously.  In a nutshell it sneaks up and takes away a lot of the parenting skills over time.

Additionally infants that are not congenital in nature may have the juvenile onset. This can cause issues with learning disability, social, emotional and other considerations. This will cause a lot of stress on the family and the mom who may be the primary caretaker.

Some issues that women need to consider

1. The need to consider reproduction via Pre-Implant diagnosis
2. The need to care for an infant with Juvenile or Congenital DM1
3. Increased Menstrual Pain or Bleeding
4. Pregnancy

Congential Myotonic Dystrophy Analysis of US National Registry

Editors Note: This article is an analysis of the US registry. The US registry is a highly biased sample of patients with Myotonic Dystrophy. The registry has very few members with CMD and the questionnaires that are sent out do not deal with questions or issues with the Congenital form of DM. While the information here is somewhat useful many of the symptoms and issues of patients with CMD are not included.

The percentage of the population with DM in the USA registered is less than 5% leading to a highly biased sampling.

Congenital myotonic dystrophy in a national registry
Paediatr Child Health. 2010 October; 15(8): 514–518.

Abstract

AIM:

To describe the neonatal symptoms, developmental problems and chronic multisystem medical morbidities of congenital myotonic dystrophy (CDM) patients registered in the United States National Registry of Myotonic Dystrophy – a disease-specific, self-report program maintained since 2002. Comparisons with the Canadian Paediatric Surveillance Program for CDM are highlighted.

CANADA

This page contains information and support for people with Myotonic Dystrophy in Canada.
Canada is a country with a centralized medical system. There is additional support for people with myotonic dystrophy in Quebec, as there is a high incidence of Myotonic Dystrophy in this Country. There is also a center for Congential Myotonic Dystrophy research and Dr. Craig Campbell is an expert in this disease. His contact information is at the end of this post.
