This review explores the current model of sickle cell nephropathy and the limitations of the model. Renal abnormalities are common complications of sickle cell disease (SCD). Beginning in childhood, patients with SCD develop a urinary concentrating defect resulting in polyuria and a predisposition to nocturnal enuresis and dehydration. The current model of sickle cell nephropathy suggests that destruction of the renal medulla induces production of renal vasodilating substances that feedback to the glomerulus causing hyperfiltration. Hyperfiltration leads to glomerulosclerosis and proteinuria, with eventual reduction in kidney function. The crucial steps of vasodilating substance production and hyperfiltration in children with SCD have not been proven. Treatment of sickle cell nephropathy is aimed at the reduction of proteinuria with angiotensin converting enzyme inhibitors or angiotensin receptor blockers. Hydroxyurea and chronic transfusion therapy may also alter the progression of sickle cell nephropathy in children. Further studies are needed to identify an accurate model and effective treatments for sickle cell nephropathy.

To assess the level of adherence of patients with sickle cell disease to the advised vaccination schedule with respect to the Sickle Cell Society guidelines on vaccination [1,2].
Sickle cell anemia is a life-threatening disease, and the most common genetic disease in the world. The prevalence of sickle cell anemia in Sweden is unknown. Sickle cell anemia is an important diseas...
Availability of hydroxyurea (HU) coupled with early therapeutic interventions has increased the life expectancy of patients with sickle cell disease. Hence, the sickle cell community needs to be aware...
Sickle cell disease (SCD) substantially alters renal structure and function, and causes various renal syndromes and diseases. Such diverse renal outcomes reflect the uniquely complex vascular pathobio...
Children with sickle cell disease are at increased risk of developing bacteremia and other serious bacterial infections. Fever is a common symptom in sickle cell disease and can also occur with sickle...
This study aims to study the temporal course of sickle nephropathy and assess novel biomarkers that can predict patients prone to nephropathy.
Sickle cell nephropathy is a known complication of sickle cell anemia (SCA) manifested by increase in glomerular filtration rate (glomerular hyperfiltration) and results in proteinuria and...
To determine the retinal and choroidal thickness in patients with sickle cell disease compared to age, race matched population without sickle cell disease to allow a better understanding o...
The purpose of this study is to determine the safety and clinical effects of SCD-101 when given to adults with sickle cell disease. SCD-101 inhibits sickling of red blood cells containing ...
To continue studies on the two major neurological complications of sickle cell disease (SCD): namely, stroke and chronic encephalopathy.
An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia.
One of the sickle cell disorders characterized by the presence of both hemoglobin S and hemoglobin C. It is similar to, but less severe than sickle cell anemia.
An acute purulent infection of the meninges and subarachnoid space caused by Streptococcus pneumoniae, most prevalent in children and adults over the age of 60. This illness may be associated with OTITIS MEDIA; MASTOIDITIS; SINUSITIS; RESPIRATORY TRACT INFECTIONS; sickle cell disease (ANEMIA, SICKLE CELL); skull fractures; and other disorders. Clinical manifestations include FEVER; HEADACHE; neck stiffness; and somnolence followed by SEIZURES; focal neurologic deficits (notably DEAFNESS); and COMA. (From Miller et al., Merritt's Textbook of Neurology, 9th ed, p111)
The condition of being heterozygous for hemoglobin S.
The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
