Hydroxyurea

Hydroxycarbamid

On cessation of HU the DM-LE clears avoiding unnecessary immunosuppression and demonstrating the importance of consideration of medication aetiology in DM presentations. We present a case report and review of the literature. [ncbi.nlm.nih.gov]

An 18-year-old woman with sickle cell anemia presents with recurrent painful crises, and treatment with hydroxyurea is recommended. Hydroxyurea causes a shift toward the production of red cells containing fetal hemoglobin. [doi.org]

  • Excessive Daytime Sleepiness

    Excessive daytime sleepiness (EDS) has been reported with many drugs, either as an extension of a hypnotic effect (e.g. central nervous system depressants) or as an idiosyncratic response of the patient. [ncbi.nlm.nih.gov]

  • Respiratory Insufficiency

    We describe intrathoracic and symptomatic pelvic EH masses in a 48-year-old woman and intrathoracic bilateral masses causing respiratory insufficiency with pleural effusion in a 42-year-old male, both affected by thalassaemia intermedia. [ncbi.nlm.nih.gov]

  • Pleural Effusion

    We describe intrathoracic and symptomatic pelvic EH masses in a 48-year-old woman and intrathoracic bilateral masses causing respiratory insufficiency with pleural effusion in a 42-year-old male, both affected by thalassaemia intermedia. [ncbi.nlm.nih.gov]

  • Foot Ulcer

    Here we describe a diabetic patient with foot ulcer associated with HU treatment for polycythemia vera, who was treated successfully with hyperbaric oxygen and general wound care after discontinuation of HU. [ncbi.nlm.nih.gov]

  • Social Isolation

    MMAS-8 scores positively correlated with fetal hemoglobin (HbF) (r s 0.34, P 0.04) and mean corpuscular volume (MCV) (r s 0.42, P 0.01) and inversely correlated with fatigue (r s -0.45, P 0.01), depression (r s -0.3, P 0.08), and social isolation (r s [ncbi.nlm.nih.gov]

  • Recurrent Headache

    Our first case had platelets 1,500,000/mm(3), and a second child was symptomatic with recurrent headache. Both responded well to therapy with hydroxyurea (dose 15-30 mg/kg/day) and tolerated it well. [ncbi.nlm.nih.gov]

  • Albuminuria

    Albuminuria normalized in 37.5% (6/16) after 1 year and 61% (8/13) after 2 years of HU therapy. Among those without albuminuria prior to HU, 13% (6/47) developed albuminuria during HU therapy. [ncbi.nlm.nih.gov]

  • Macrocytosis

    […] patients develop some toxicity, which may occur at any time during a course of treatment: Leucopaenia (reduced white cell count) Anaemia (reduced red cell count) Thrombocytopenia (reduced platelet count) Pancytopaenia (reduction in all blood cell types) Macrocytosis [dermnetnz.org]

    The macrocytosis which occurs in almost all patients on hydroxyurea may contribute as these macrocytes circulate poorly through the capillary network. [omicsonline.org]

    You may be given folic acid supplements to prevent a side effect called macrocytosis which is an enlarging of red blood cells. [oncolink.org]

  • Pleural Effusion

    We describe intrathoracic and symptomatic pelvic EH masses in a 48-year-old woman and intrathoracic bilateral masses causing respiratory insufficiency with pleural effusion in a 42-year-old male, both affected by thalassaemia intermedia. [ncbi.nlm.nih.gov]

Complete remission was observed after 6 to 10 weeks of imiquimod 5% (10 mg/cm of skin cancer) treatment. [ncbi.nlm.nih.gov]

We know that patients who have intolerance to hydroxyurea, due to hematologic toxicity, are patients defined in a couple of studies as having a worse prognosis. [targetedonc.com]

Awareness of the possibility of necrotizing fasciitis following hip replacements is warranted in patients with MPNs on hydroxyurea as the prognosis is poor without early aggressive treatment with antibiotics and surgical debridement. [omicsonline.org]
