background recent studies regarding the effect of hydroxyurea (hu) in thalassemia have revealed favorable effects on the reduction of ineffective erythropoiesis. objectives the aim of the current study was to evaluate whether or not hu can have an effect on the gallstone formation rate in patients with beta-thalassemia intermedia (bti). patients and methods in this case control cross-sectional ...
We investigated the influence of nitrovasodilators on DNA synthesis in cultured human aortic smooth muscle cells and explored the hypothesis that nitric oxide (NO) is directly involved in mediating the inhibitory effects of hydroxyurea on DNA synthesis. Both NO and hydroxyurea inhibited ongoing DNA synthesis and S phase progression in our cells. Exogenous deoxynucleosides partially reversed thi...
BACKGROUND Sickle cell anemia is a hemoglobinopathy caused by a mutation that results in the production of an abnormal hemoglobin molecule, hemoglobin S (Hb S). This is responsible for profound physiological changes, such as the sickling of red blood cells. Several studies have shown that hydroxyurea protects against vaso-occlusive crises. OBJECTIVE The aim of this study was to evaluate the o...
The long-term efficacy and toxicity of hydroxyurea for infants are undefined, and its role in preventing organ dysfunction is unknown. Short-term feasibility of hydroxyurea administration, toxicities, hematologic effects, and effect on spleen function in infants with sickle cell anemia (SCA) were reported (Hydroxyurea Safety and Organ Toxicity [HUSOFT] trial). These infants completing 2 years o...
Hydroxyurea has many characteristics of an ideal drug for sickle cell anemia (SCA) and provides therapeutic benefit through multiple mechanisms of action. Over the past 25 years, substantial experience has accumulated regarding its safety and efficacy for patients with SCA. Early proof-of-principle studies were followed by prospective phase 1/2 trials demonstrating efficacy in affected adults, ...
Factors that influence the choice of anagrelide, hydroxyurea, or interferon-alfa (IFN-alpha) for treatment of essential thrombocythemia include efficacy, toxicity, and cost. Anagrelide has the US Food and Drug Administration's approval to be used for treating patients with thrombocythemia secondary to chronic myeloproliferative disorders. In contrast, the use of IFN-alpha and hydroxyurea are co...
We report a 41 year old male with sickle cell disease who developed a myelodysplastic syndrome and acute myeloid leukemia with complex karyotype involving chromosomes 5, 7 and 17 after 15 years of hydroxyurea treatment. He responded poorly to induction chemotherapy with cytarabine/idarubicin followed by high dose cytarabine and succumbed to neutropenic sepsis. Multiple systematic reviews, obser...
Hydroxyurea has been extensively used in medical practice, mainly for treating chronic myelogenous leukemia, sickle cell anemia, and other diseases. In light of its ability to inhibit DNA synthesis and to induce cell cycle arrest through inhibition of ribonucleotide reductase, the effects of hydroxyurea on replication of human immunodeficiency virus type 1 (HIV-1) have been investigated. In vit...

AIM The aim of this work was to retrospectively analyze patients with Philadelphia-negative myeloproliferative neoplasms through evaluation of frequency and characteristics of second malignancies (other than acute leukaemia and myelodysplastic syndrome). PATIENTS AND METHODS Records of 172 patients were reviewed; an analysis was performed on data from 66 patients treated with hydroxyurea, 105...
