Serious side effects that have been reported with Hydrea and their symptoms include: Severe skin ulcers (sores) and gangrene (tissue death). Backward elimination was applied to reduce the model to the subset of statistically significant variables while continuing to retain the inclusion of the above predetermined covariates. and transmitted securely. loss of appetite. Univariate analysis of subject-level predictors of miscarriage and stillbirth combined are shown in Supplementary Table 2; these include demographics, sickle cell type, pregnancy number, age at pregnancy, history of stillbirth or miscarriage at time of pregnancy, measures of sickle cell disease severity, hydroxyurea use at enrollment, hydroxyurea use at conception only, and hydroxyurea use at conception and during pregnancy. This trend was also observed in surviving patients aged 50 years at hydroxyurea initiation (122.212.4 vs. 187.830.7, p=0.03). Drug information provided by: Merative, Micromedex. It is a treatment for: chronic myeloid leukaemia (CML) polycythaemia vera (PCV) essential thrombocythemia (ET) acute myeloid leukaemia (AML) cervical cancer (cancer of the neck of the womb) This is consistent with a 17 year follow up of patients in the Multicenter Study of Hydroxyurea, which concluded that exposure to hydroxyurea during pregnancy did not result in congenital anomalies of children born live to mothers with sickle cell disease.25 However, we did find that hydroxyurea use at both conception and during pregnancy was independently associated with miscarriage and, in the infants that had a live delivery, with birth weight less than 5.5 pounds. Hydroxyurea use at conception and during pregnancy was significantly associated with miscarriage (OR [95% CI] 2.51 (1.12-5.51) while hydroxyurea use at conception alone or also during pregnancy was not significantly associated with stillbirth. Hydroxyurea (Hydrea) is used alone or with other medications or radiation therapy to treat a certain type of chronic myelogenous leukemia (CML; a type of cancer of the white blood cells) and certain types of head and neck cancer (including cancer of the mouth, cheek, tongue, throat, tonsils, and sinuses). The difference between these two studies was attributed to different follow-up periods of patients or different doses of hydroxyurea used in the centers [26]. It was once also called Hydroxyurea. Reference groups for odds ratios were age 18-25 at pregnancy and those without the characteristic or condition. However, we should accept that limited retrospective data quality (particularly the ambiguity about the definition of massive splenomegaly and the data concerning duration of hydroxyurea used at a dose of 2 g) might have obscured the exact figure. Complete blood count values during the last follow-up visits of the patients still on hydroxyurea therapy are demonstrated in Table 5. Descriptive statistics were expressed as numbers and percentages for categorical variables and as mean standard deviation or median (standard error [SE]) (range or interquartile range) for numerical variables. in the expression of biotin receptors (Russell-Jones et al., 2004). Conflict of Interest: Y.B., R.A., M.T., G.S., A.S.Y., A.., M.C.A., O.A., F.A., and T.T. Review/update the Thus, more data are required to show the patterns of hydroxyurea treatment of PV patients in daily practice and also the impact of these patterns on the treatment outcomes. Common side effects of hydroxyurea include infections, viral infections, bacterial infections, gastrointestinal disorders, low count of . We found that a substantial number of pregnancies reported by women with sickle cell disease were conceived while on hydroxyurea. Among 1285 women 18-45 years of age, 737 (57.4%) reported 1788 pregnancies (1079 live births, 394 miscarriages, 40 stillbirths, 207 abortions, 48 current pregnancies, and 20 missing outcomes) of which 241 (15.9%) live births, miscarriages or stillbirths were conceived while on hydroxyurea. As having been prescribed hydroxyurea can be regarded as a surrogate for having more severe sickle cell disease, we also included current hydroxyurea use and four measures of clinical severity of the mother at enrollment (hemoglobin level, history of chronic kidney disease, history of pulmonary hypertension, and number of healthcare encounters for acute pain in the previous year) as covariates. The mutation status was unknown in 14.9% of the patients. government site. Ethical approval was received by the institutional review boards at each of the eight SCDIC study sites prior to data collection efforts. For live births, there does not appear to be an increase in birth defects when hydroxyurea is used during pregnancy. health information, we will treat all of that information as protected health Second-line treatment (standard/PEGylated interferon-alpha or JAK inhibitor ruxolitinib) should be considered for patients with hydroxyurea resistance/intolerance [6,7]. Portions of this document last updated: May 01, 2023. To attempt to account for this, we adjusted for markers of severity to the extent the data allowed, including hemoglobin concentration and histories of chronic kidney disease, pulmonary hypertension and frequent pain episodes at the point of entry into the registry. On the other hand, only 20.5% received 2 g/day hydroxyurea at any time during the disease course. Of the patients, 50.9% (295/579) were in the high-risk group (age 60 years and/or history of a thrombotic event) at diagnosis. In a cross-sectional study from Belgium, 12% of the patients were reported to have hydroxyurea resistance/intolerance [13]. Characteristics and treatment of polycythemia vera patients in clinical practice: a multicenter chart review on 1476 individuals in Germany. Arterial and venous thromboses have been known as the major causes of morbidity and mortality in PV patients [2]. Pregnancy outcomes in women with sickle-cell disease in low and high income countries: a systematic review and meta-analysis, Adverse maternal and perinatal outcomes in pregnant women with sickle cell disease: systematic review and meta-analysis, The sickle cell disease implementation consortium: Translating evidence-based guidelines into practice for sickle cell disease, Patient-reported Outcomes in Sickle Cell Disease and Association with Clinical and Psychosocial Factors: Report from the Sickle Cell Disease Implementation Consortium. Napumpujte ho antioxidantmi a vitamnmi! Clinical trial registration: not applicable, National Library of Medicine There was a trend toward an association between hydroxyurea use at conception and during pregnancy with stillbirth (OR 2.6) that did not reach significance, perhaps due to the small number of events. and E.G. Of the total drug interactions, 52 are major, 181 are moderate, and 15 are minor. The estimated risks at 10 years were 6.2% and 8%. In a cross-sectional survey from Belgium, 343 PV patients were evaluated and 74.6% of them were 60 years of age [13]. However, the impact of these developments on routine PV care has not been sufficiently documented. The chi-square test was used to compare independent categorical variables, whereas Students t-test was used to compare numerical variables. Patterns of hydroxyurea use and clinical outcomes among patients with polycythemia vera in real-world clinical practice: a chart review. Hidroksire kesme oran kadnlarda daha yksektir. Although no formal sample size calculation was performed in the present study, the number of patients to be enrolled in each province was calculated based on the overall population and a maximum of 700 patients were expected to be enrolled. Click here for an email preview. However, this approach is not perfect.21,22 A study from Norway found that among mothers with a previous pregnancy loss documented in the record, 73.5% had a recall of this loss.23 Our finding that severe sickling genotype in this study is a significant predictor of miscarriage, still birth and prematurity is consistent with a number of studies of pregnancy outcomes in sickle cell disease by other investigators,12 and this helps address concerns that our findings are overly biased by a reliance on patient recall for the outcomes. Mayo Clinic does not endorse companies or products. Hydroxyurea reduces pain crises, acute chest syndrome and blood transfusions in sickle cell disease (SCD), but potential detrimental effects on fertility and birth outcomes impede its use. Introduction. It remains a vital disease-modifying therapy. Differences in characteristics were determined by Chi-square, Wilcoxon rank sum, or T-tests, as appropriate for variable type and distribution. NHLBI, NIH, 2014, https://www.nhlbi.nih.gov/sites/www.nhlbi.nih.gov/files/sickle-cell-disease-report.pdf, Other serious medical problem in the infant, Acute pain visits past year (no. 5 . We also limited the Kaplan-Meier analysis to surviving patients aged 50 years at hydroxyurea initiation in order to understand if the main reasons for hydroxyurea discontinuation were fertility/teratogenicity concerns or death. 1.62 [1.08-2.46]), history of stillbirth or miscarriage (OR [95% CI] 1.94 [1.36-2.75]), and chronic kidney disease at time of enrollment (OR [95% CI] 1.50 [1.01-2.20]), but a higher number of visits for acute pain in the year prior to enrollment (OR [95% CI] 0.98 [0.96-1.00]) was significantly associated with a lower risk of miscarriage. HHS Vulnerability Disclosure, Help Hydroxyurea is an antineoplastic (anti-cancer) agent used to treat melanoma, resistant chronic myelocytic leukemia, and recurrent, metastatic, or inoperable carcinoma of the ovary and primary squamous cell (epidermoid) carcinomas of the head and neck. Does Viagra Have an Effect on Women? Hydrea may cause serious side effects. Does hydroxyurea interact with my other drugs? The predicted time until hydroxyurea discontinuation was 187.8 months (standard error: 21.7) for all patients. Secondary myeloid neoplasms (i.e. On the other hand, women that continue taking hydroxyurea during pregnancy may have an inceased risk of a low fetal viability or low infant birth weight. The present study, which was planned as a retrospective, descriptive, non-randomized study, involved the review of patient charts obtained from hematologists working in 10 study centers. In contrast, tThe odds of a pregnancy ending in a miscarriage were 2.21 times higher when hydroxyurea was used at conception and during pregnancy (95% CI 1.38-3.50) compared with no hydroxyurea use after adjusting for covariates. The V617F mutation of the Janus kinase None of the covariates were significantly associated with either miscarriage or stillbirth. In the best fitting multivariate models (Table 3), hydroxyurea use at conception only was not associated with any of the live birth outcomes and hydroxyurea use at conception and during pregnancy was associated with low birth weight (OR [95% CI] 2.98 [1.09-7.38]) but not the other live birth outcomes, including birth defects. pain, itching . acute myeloid leukemia or myelodysplastic syndrome) and post-PV myelofibrosis during hydroxyurea treatment were reported in 3 and 7 cases, respectively. In analyses of live birth outcomes, hydroxyurea use during conception and pregnancy was associated with birth weight <5.5 pounds in full-term infants (OR 2.98, 95% CI 1.09-7.38) but not with prematurity or serious medical problems at birth. Of the patients who were still on hydroxyurea therapy, 40.3% had a hematocrit concentration of 45%, 29.2% had a platelet count of >400109/L, and 34.4% had a WBC count of >10x109/L. It was observed that the most common initial hydroxyurea dosage was 500 mg BID (41%), followed by 500 mg QD (33.5%). Additional limitations are that we do not have information regarding the dose and duration of hydroxyurea use, the type and dose of opioids and other medications used during each pregnancy, or concurrent co-morbidities in the mother which could affect fetal outcomes.
