While necessary in muscle tissue to bind iron and oxygen, myoglobin circulating through the bloodstream can break down into smaller compounds that damage kidney cells, leading to various complications, such as those seen in sickle cell trait athletes during high levels of physical exertion.
Problems in sickle cell disease typically begin around 5 to 6 months of age. [1] A number of health problems may develop, such as attacks of pain (known as a sickle cell crisis) in joints, anemia, swelling in the hands and feet, bacterial infections, dizziness [9] and stroke. [1]
Kidney complications of sickle cell disease include cortical infarcts leading to loss of function, persistent bloody urine, and perinephric hematomas. Papillary infarcts, demonstrable radiographically in 50% of patients with sickle trait, lead to an increased risk of bacterial infection in the scarred kidney tissues and functional tubule ...
A sickle cell health crisis can escalate into life-threatening complications, but patients still struggle to get seen quickly in emergency rooms and also to get pain medicine.
Proliferative sickle retinopathy is the most severe ocular complication of sickle cell disease. Even though PSCR begins in the first decade of life, the condition remains asymptomatic and unnoticed until visual symptoms occur due to vitreous hemorrhage or retinal detachment.
The misshapen cells clog the flow of blood, which can lead to infections, excruciating pain, organ damage and other complications. The disease, which can stunt physical growth, is more common in ...
Signs and symptoms. The crisis is a common complication in sickle-cell patients and can be associated with one or more symptoms including fever, cough, excruciating pain, sputum production, shortness of breath, or low oxygen levels. [2]
The finding that virtually all people affected by renal medullary carcinoma carry at least one copy of the HbS mutation suggests that sickle cell trait somehow predisposes to this type of cancer. The precise mechanism is unknown, but red blood cells with a sickle cell configuration have been identified in pathology specimens.
Transfusion therapy for sickle-cell disease entails the use of red blood cell transfusions in the management of acute cases of sickle cell disease and as a prophylaxis to prevent complications by decreasing the number of red blood cells (RBC) that can sickle by adding normal red blood cells.
Sickle cell-β thalassemia. Specialty. Hematology. Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease. [1] [2]
