Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
It is possible for a person to have both the gene for hemoglobin S (the form associated with sickle cell anemia) and the gene for hemoglobin C; this state is called hemoglobin SC disease, and is generally more severe than hemoglobin C disease, but milder than sickle cell anemia.
The clinical result is a rise in blood K+ level and drop of blood Na+ levels There are a wide range of possible pathological conditions that can cause sick cell syndrome, including: [citation needed] hypoxia; sepsis; hypovolaemia; malnourishment; This syndrome is well known in the field of palliative medicine as many terminal patients develop ...
For people living with the disease, a sickle cell crisis can happen at any time. When it does, their rigid, sickle-shaped red blood cells become stuck in their blood vessels, blocking flow and ...
A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. [1] [2] It is a form of sickle cell crisis.Sickle cell anemia – most common in those of African, Hispanic, and Mediterranean origin – leads to sickle cell crisis when the circulation of blood vessels is obstructed by sickled red blood cells, causing ischemic injuries.
The diagnosis of acute chest syndrome is made difficult by its similarity in presentation with pneumonia. Both may present with a new opacification of the lung on chest x-ray. The presence of fevers, low oxygen levels in the blood, increased respiratory rate, chest pain, and cough are also common in acute chest syndrome.
Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot. [3]
Sickle cell disease exhibits characteristics of either homozygous hemoglobin S, also known as Hb S, or Hb S paired with another hemoglobin variant. In diagnosing patients with sickle cell, HbA2 is taken into account alongside a complete blood count, family history, and clinical data.
