Answer 1

Hint: Christmas disease is a genetic disorder in which the blood of affected people cannot clot easily.

Complete Answer:
Christmas disease: Christmas disease is also called as Haemophilia B or factor IX haemophilia.
- It is a genetic disorder in which blood does not clot easily due to which there will be spontaneous bleeding and sometimes leads to death.
- Haemophilia B disease is also called as Christmas disease named after its first patient, Stephen Christmas.

Symptoms of Christmas disease:
- Urinary tract bleeding called as hematuria
- Nosebleeds called as epistaxis
- Bleeding into joints called as hemarthrosis
- Diagnosis of Christmas disease:

There are many tests for the diagnosis of Christmas disease.
- Bleeding scores
- Coagulation test assay
- Coagulation screening test

Treatment: It can be treated by giving factor IX injection to the patients in order to prevent or stop bleeding.
- The factor IX can be made in the laboratory or can be donated by humans.

Hence, option A is the right answer for this question.

Note: In haemophilia patients can lose a large amount of blood even on a small injury. If a patient didn’t get a proper treatment then bleeding can cause the death of a patient.
