Sickle Cell Disease

Enfermedad de células falciformes

Also: Anemia de células falciformes (regional variant)

What it means

Sickle cell disease (SCD) is a group of inherited red blood cell disorders. In SCD there is a problem with hemoglobin, a protein in red blood cells that carries oxygen throughout the body: the hemoglobin forms into stiff rods within the red blood cells and changes their shape. The cells are supposed to be disc-shaped, but instead they are crescent, or sickle, shaped. Many of them burst apart as they move through the blood vessels, so a person may not have enough red blood cells, a condition called anemia. The sickle-shaped cells can stick to vessel walls and cause a blockage, and the lack of oxygen can cause attacks of sudden, severe pain, called pain crises. People with SCD are born with two sickle cell genes, one from each parent.

Enfermedad de células falciformes is feminine: la enfermedad de células falciformes. It is the title of the MedlinePlus en español page and the headword in the National Cancer Institute's Spanish dictionary. That dictionary adds that the disease is also called anemia de células falciformes, drepanocitemia and drepanocitosis, and the Spanish dictionary has an entry for drepanocitosis as a medical term. In English, the National Cancer Institute likewise says the disease is also called sickle cell anemia.

MedlinePlus en español describes the cells as having the shape de medialuna o de hoz (crescent or sickle) and calls them células falciformes. Sickle cell trait, having one sickle cell gene, is rasgo de células falciformes; the same page also writes rasgo drepanocítico. A pain crisis is una crisis de dolor, red blood cells are glóbulos rojos, and hemoglobina and anemia are close to their English forms.

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
