World Rare Disease Day: definition, treatment, care and discussion

World Rare Disease Day: definition, treatment, care and discussion

What is a rare disease?

A rare disease is a disease that affects very few people: less than one in 2,000 in the European Union, less than one in 1,500 in the United States. Rare diseases affect 25 million people in Europe and 27 million in the United States. Thus, some of them concern thousands of people, others only a few individuals. More than 8,000 rare diseases have been identified but their diagnosis is difficult because of the small number of patients and because the symptoms can vary widely from one person to another. One in three patients are not diagnosed for their condition.

80% of these rare diseases have a genetic origin, sometimes hereditary. The vast majority of rare diseases are called "orphan" diseases, which means that there is no treatment. Yet, it is estimated that two-thirds of these diseases are serious and disabling. Patients often receive palliative care to alleviate symptoms, preserve their quality of life and extend their life expectancy, but many do not recover.

Treatments for rare diseases

It is difficult to train health professionals in all these diseases that affect only a few patients, especially since multidisciplinary management is often required to help patients. Coordination between doctors and specialists is essential to train the patient to adopt a healthy lifestyle, to understand their disease and to receive appropriate care.

Treatments are also expensive to develop by laboratories because they will only be used by a limited number of people. That is why donations from individuals are so important to help research. Nevertheless, in the United States and Europe, aids and procedures are in place to promote research on these orphan diseases. 40% of the molecules currently developed in the European Union concern rare diseases and 410 drugs are in development. On 22 and 23 March 2019, the first European Congress on e-Health and Innovation in Neuromuscular Diseases will also be held, bringing together the largest European congregation of e-Health professionals involved in neuromuscular diseases, particularly rare diseases.

Gene therapy and cell therapy

These two therapies are innovative processes that are favoured by research to treat rare diseases. Gene therapy consists of inserting into the patient's cells a normal version of a gene that does not work and is at the origin of the disease. The functional gene then allows the patient to produce again the protein whose deficiency was the source of the disease.

Cell therapy is the grafting of cells to repair or regenerate a damaged organs or tissue. These cells, which come from the patient or a donor, are cultured to be multiplied or purified. When they come from the patient, they are modified in order to be "corrected" by transfer of a non-ill gene or by correction of the gene.

Public policies on rare diseases

The US has aimed at supporting public health approaches and reduce the burden of the patients affected by a rare condition : as early as 1983, Congress passed the Orphan Drug Act, the first major federal statute for rare diseases. This law encouraged the production of orphan drugs (medication developed to treat rare diseases) by providing financial incentives to pharmaceutical industries to offset the potential losses of marketing drugs to such a small market. It includes research grants, tax credits, fee waivers and a seven-year market exclusivity for approved medication.

Other pieces of legislation in the US include the Rare Disease Act, which established the Office of Rare Diseases at the National Institutes of Health (NIH) and legislation for single rare diseases, such as the MD Care Act (for Muscular Dystrophy Community Assistance, Research and Education Amendments of 2001).

Rare diseases on Carenity

Carenity strives to identify as many pathologies as possible so that everyone can express themselves. You can search for them in order to add them to your profile by clicking here. This will make it easier for you to access ongoing discussions on the subject. Even if there is no discussion group dedicated to your illness or that of your loved one, there are multi-pathology forums, such as nervous system diseases, cardiovascular diseases, skin diseases, kidney diseases, diseases affecting the immune system or muscles, joints and skeletons, diseases of the respiratory and digestive systems, liver diseases, etc.

Other groups we have created seek to address general themes that all patients and their loved ones, whether they have a rare disease or not, may face:

-Faced with the administrative difficulties shared by many patients, visit our forum dedicated to rights and administrative procedures.

-Is your illness or that of your loved one painful? Discussions are ongoing on our group "Living with chronic pain"

-Is it your child who is concerned? Talk about your fears, treatments and daily life on our group dedicated to parents of sick children.

Join the discussion groups that interest you so you don't miss any of the ongoing discussions!
