Rare diseases tend to be forgotten because they affect a small group. Therefore, those affected pay the consequences of the lack of health equity. However, its world day seeks to raise awareness.
Being sick represents an unfavorable scenario in which there is a certain degree of uncertainty. However, suffering from a disease of which little is known and that the health system is not prepared to deal with, is a drama. Out of this adverse situation, World Rare Diseases Day has been created, an initiative to raise awareness and advance.
The last day of February was the date selected for a campaign to reduce the isolation of those affected by rare diseases. In addition, it is sought that medicine also advances in favor of atypical diseases that, according to data from the World Health Organization (WHO), harm 7% of the world’s population.
Indeed , we consider that there is no better time to clarify what a rare disease is, some historical data about it, how to help a diagnosed person and how you can support yourself on the commemoration day.
What is a rare disease?
A rare disease is any pathology that affects a small sector of the world population. Taking it to the numbers, the disease is considered rare when it affects fewer than 5 people per 10,000 inhabitants. Besides, an approximate of 7000 strange diseases is estimated. These are some of the most anomalous.
Ebstein anomaly
Ebstein’s anomaly is a disease or defect in the heart that occurs from birth. What happens is that the tricuspid valve has an inaccurate location. On the other hand, the valve flaps do not have a normal structure. The consequences can be an enlarged heart, heart failure, or leakage of blood through the valve.
Moebius syndrome
Moebius syndrome is considered a rare and congenital neurological condition that causes paralysis of the face. Also, there are variations in ocular abduction, swallowing problems, deficiency in correct pronunciation, among others. Its origin is in the underdevelopment of cranial nerves 6 and 7.
Chediak-Higashi disease
Chediak-Higashi disease is caused by a recessive modification and mutation in the lysosomal gene. The consequences of this abnormality are noted in the body’s defenses, since they fail to fulfill the functions of containing external agents that attack the body.
In this way, the phagocytic function – which consists in the selective elimination of damaged cells or microbes – is limited. The foregoing brings as a ramification problems of anemia, repetitive infections and an increase in the size of the liver.
Bardet-Biedl syndrome
It is an autosomal recessive disease that affects different areas of the body. Obesity, reproductive organ malfunction, mental retardation, polydactyly, and heart defects can occur, to name the main alterations.
Hermansky-Pudlak syndrome
It is a genetic and multisystemic disorder that comprises 8 independent disorders. Some of these disorders are oculocutaneous albinism, pulmonary fibrosis, granulomatous kidney disease, hemorrhagic disease, and so on.
Expanding on the above information a bit, other rare diseases, but that present a higher relative frequency, are in the following list:
