Activity 3: Read the text and answer the questions.

Rare diseases

There is currently no consensual definition of what is a rare or orphan disease: in Europe, a disease is considered rare if it affects less than 1 in 2000 citizens, while in United States of America (USA), the threshold was set at 200,000 in the entire population (approximately 1 in 1600). The term health orphan describes a person who is affected by a rare disease.

Most genetic diseases are rare diseases, but some infectious diseases, cancer and auto-immune diseases are also rare. Screening tests are used to identify newborns in high risk groups.

Geographical variations also occur, so that some diseases can be rare in one country but quite frequent in another. For example, Familial Mediterranean Fever, an inherited condition, is more common in people of Sephardic Jewish, Armenian, Arab or Turkish heritage.

Some rare diseases are well known and have been well-studied, however, some are recent discoveries. Patients who are diagnosed with a recently discovered rare disease often have difficulties finding a physician with sufficient experience in its treatment and physicians may also struggle to develop treatment plans without available care pathways.

Rare diseases can be neglected because treatment options are not considered profitable due to high development costs and use on a limited patient population. Despite this, the ‘paradox of rarity’ means that, although each rare disease may be uncommon, there are between 5000 and 8000 rare diseases in total.

Medications which are available to treat rare diseases are classified as orphan drugs.

Like rare disease, neglected diseases are not considered a priority by pharmaceutical companies. Neglected diseases include infectious tropical diseases, e.g. sleeping sickness as well as conditions such as lead poisoning. Neglected diseases often affect people in poorly funded countries.

Before a new drug to treat a rare disease is approved, a cost assessment per quality adjusted life year of QALY is made. An orphan drug is one where there is a reasonable expectation of recuperating development costs.
