however, data comparing the impact of different hU doses on length of stay (lOs) and clinical outcomes in adults are limited. Methods: this retrospective study assessed the effect of high- versus low-dose hU on lOs among adults with scD admitted to medical wards. secondary endpoints included VOc frequency and hemoglobin electrophoresis findings. Pearson’s chi-square and Mann–Whitney tests were used, with significance set at p \u003C 0.05.  \nResults: a total of 141 patients were analyzed (26 on low-dose, 115 on high-dose hU), with a median age of 31 years; 52.5% were female. the overall median lOs was 3 days (iQR 1–10). the low-dose group had a significantly longer median lOs (7 days [iQR 7–9]) compared with the high-dose group (2 days [iQR 2–3]; p \u003C 0.001). higher hU doses were also associated with improved hgb F% and hgb s%(p \u003C 0.001), while annual VOc rates showed no significant difference (p = 0.132).  \nConclusion: high-dose hU was linked to shorter hospital stays and favorable hematologic outcomes in adults with scD.  \nPLAIN LANGUAGE SUMMARY  \nthis study focuses on how hydroxyurea (hU), a common medication for sickle cell Disease (scD), affects hospital stays and blood health in adults.  \nPatients with sickle cell Disease often experience “pain crises” (vaso-occlusive crises) that require hospital treatment. While we know hU helps prevent these crises, there isn’t enough information on whether the size of the dose makes a difference in how long a patient stays in the hospital. the researchers looked at 141 adults with scD. they compared two groups:  \n• low-dose group: 26 patients.  \n• high-dose group: 115 patients.  \nthey measured the length of stay (lOs)—the number of days a patient spent in the hospital—and checked their blood levels to see how well the medication was working. the study found that patients on a higher dose of hU had much better outcomes:  \n• shorter hospital stays: Patients on high doses stayed in the hospital for a median of 2 days, while those on low doses stayed for 7 days.  \n• Better Blood levels: high doses led to better levels of “fetal hemoglobin” (hgb F), which helps protect against cell damage.  \n• Pain crises: Both groups had similar yearly rates of pain crises, but the severity or recovery time appeared to favor the high-dose group.  \nARTICLE HISTORY  \nReceived 21 October 2025  \naccepted 23 December 2025  \nKEYWORDS  \nsickle cell disease; sickle; scD; hydroxyurea; vaso-occlusive crisis  \nCONTACT Musa Alzahrani  [malzahrani@ksu.edu.sa](malzahrani@ksu.edu.sa)  Department of Medicine, King Saud university, Saudi Arabia, P O Box: 55068 (37), King Khalid road, riyadh, riyadh Prov","cbCaikvecnn8bles","https://ap.wps.com/l/cbCaikvecnn8bles","pdf",487898,"English","# Abstract\n## Background & Aims\n## Methods\n## Results\n## Conclusion\n# Plain Language Summary\n## Study comparison and outcomes\n# Keywords\n# Article Highlights\n# Introduction","[{\"question\":\"How does HU dose relate to hospital length of stay in adults with SCD?\",\"answer\":\"In the study, adults on high-dose HU had a significantly shorter median length of stay (2 days) than adults on low-dose HU (7 days; p \\u003c 0.001).\"},{\"question\":\"What secondary outcomes were assessed besides length of stay?\",\"answer\":\"The study assessed VOC frequency and hemoglobin electrophoresis findings, including fetal hemoglobin (HbF) and hemoglobin S (HbS) percentages.\"},{\"question\":\"Did higher-dose hydroxyurea change annual VOC rates?\",\"answer\":\"No. Annual VOC rates showed no significant difference between the low- and high-dose groups (p = 0.132).\"},{\"question\":\"What overall conclusion did the authors draw about high-dose HU?\",\"answer\":\"High-dose HU was associated with shorter hospital stays and favorable hematologic outcomes, including improved HbF and HbS parameters in adults with SCD.\"}]","Does the dose of hydroxyurea correlate with shorter hospital stay and higher fetal hemoglobin levels in patients with sickle cell disease? - Research Article | PDF",1790757802,18]
