One of the main problems in sickle cell disease is the decreased bioavailability of nitric oxide and arginine. This study was designed to assess if treating sickle cell disease patients with L-arginine would improve pulmonary arterial pressure and other aspects.
This is a phase III, randomized, double-blind, placebo-controlled clinical trial with sickle cell disease patients older than 1 year of age. The patients were randomly assigned to take 0.1 g/kg/day of either L-arginine or placebo orally. Adverse events were monitored by a safety committee. The variables were assessed while patients were in remission, as part of their routine care: weight, blood pressure, full blood cell count, creatinine and dosage of methemoglobin at baseline and at each follow-up visit. Peripheral oxygen saturation (SpO2), fetal hemoglobin, lactate dehydrogenase and tricuspid regurgitant jet velocity were measured through transthoracic Doppler echocardiogram before and after treatment.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Sickle cell disease (SCD), also known as sickle cell anemia, is an inherited genetic disease that can cause intense pain episodes. This study will evaluate the effectiveness of the nutriti...
The aim of this study is to determine whether giving extra arginine, a simple amino acid, to patients with sickle cell disease seeking treatment for a pain crisis (vaso-occlusive painful e...
This is a study to determine if oral arginine will increase nitric oxide in sickle cell disease (SCD) patients with acute chest syndrome (ACS). It will also assess the effects of arginine ...
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 ...
Sickle cell disease comprises a group of genetic haemoglobin disorders. The predominant symptom associated with sickle cell disease is pain resulting from the occlusion of small blood vessels by abnor...
Sickle cell disease is an inherited hemolytic disease with systemic complications. These complications significantly impact the patients' quality of life. There are characteristic radiological finding...
Sickle cell disease affects more than 100,000 individuals in the United States, among whom disease severity varies considerably. One factor that influences disease severity is the sickle cell disease ...
A pilot study of a non-invasive oral nitrate stable isotopic method suggests that arginine and citrulline supplementation increases whole-body NO production in Tanzanian children with sickle cell disease.
Low bioavailability of nitric oxide (NO) is implicated in the pathophysiology of sickle cell disease (SCD). We designed a nested pilot study to be conducted within a clinical trial testing the effects...
Sickle cell disease (SCD), a congenital hemolytic anemia that exacts terrible global morbidity and mortality, is driven by polymerization of mutated sickle hemoglobin (HbS) in red blood cells (RBCs). ...
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 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.
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)
A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.
The condition of being heterozygous for hemoglobin S.
