NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:2701-2714. [PMID: 37979057 DOI: 10.1007/s00210-023-02817-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 10/23/2023] [Indexed: 11/19/2023]
Abstract
Daily administration of oral iron is considered the current treatment standard for treating iron deficiency anemia due to availability and reduced cost compared to intravenous iron therapy. But adverse effects like epigastric pain, heartburn, and constipation reduce compliance to daily oral iron. There is scanty evidence regarding compliance and efficacy with alternate-day iron therapy. As per our knowledge, this is the first systematic review to compare daily with alternate-day oral iron therapy. Six electronic databases including PubMed and EMBASE were searched for randomized controlled trials, quasi-experimental studies published between January 2000 to March 2023 that compared daily with alternate day iron therapy in individuals diagnosed with iron deficiency anemia. The primary outcome analyzed was a change in hemoglobin. The other hematological parameters were assessed as secondary outcomes. Risk of bias was assessed regarding randomization process, deviation from intended intervention, missing outcome data, measurement of the outcome, and selection of the reported result. Out of the 9 full-text articles, 2 were not included as one was an ongoing trial and the second one had a different study design. The reviewed trials involved 594 participants, and the study participants ranged from 19 to 200. The mean age of the participants in the reported trials was 21 ± 2 to 49 ± 16 years. There is no significant increase in hemoglobin level and also the iron indices namely ferritin, hepcidin, total iron binding capacity, and reticulocyte count between daily and alternate-day dosing of iron. However, the frequency of adverse effects especially nausea, metallic taste, and altered bowel habits are reduced with alternate-day dosing. Oral iron given daily or on alternate days did not have a significant difference in the hemoglobin levels though iron absorption may be affected in the initial few days.Trial registration: The review protocol was registered with PROSPERO (Prospero2023CRD42023393095).

Abstract
Occult and obscure bleeding are challenging conditions to manage; however, recent advances in gastroenterology and endoscopy have improved our diagnostic and therapeutic capabilities. Obscure gastrointestinal (GI) bleeding is an umbrella category of bleeding of unknown origin that persists or recurs after endoscopic evaluation of the entire bowel fails to reveal a bleeding source. This review details the evaluation of patients with occult and obscure GI bleeding and offers diagnostic algorithms. The treatment of GI bleeding depends on the type and location of the bleeding lesion and an overview of how to manage these conditions is presented.

Effectiveness of Oral Iron Therapy in Anemic Inpatient Pregnant Women: A Single Center Retrospective Cohort Study. Cureus 2024; 16:e56879.

Abstract
Background and aim Oral iron therapy is effective in treating iron deficiency anemia in outpatient pregnant women but has not been studied in inpatient pregnant women. We aimed to evaluate the effect of oral iron therapy versus no therapy during hospitalization on maternal and neonatal outcomes in women with anemia who are hospitalized for pregnancy-related morbidities (i.e., preterm premature rupture of membranes, preterm labor, pre-eclampsia, abnormal placentation, or fetal monitoring). Methods A retrospective, single-center study was conducted in hospitalized pregnant women (2018 to 2020) with inpatient stays of more than three days. The primary outcome was a change in hemoglobin level from admission to delivery in women treated with oral iron compared with those left untreated. Secondary outcomes included the total amount of iron administered before delivery, the time interval from admission to delivery, and neonatal effects. Results Two hundred sixty-three women were admitted, 79 women had anemia, and 29 (36.7%) received at least one dose of oral iron. Baseline patient characteristics were similar between groups. The median (interquartile range) dose of iron in the oral iron group was 1185.0 (477.0, 1874.0) mg. Neither absolute hemoglobin before delivery (control group: 10.0±1.2 g/dL; iron group: 10.1±1.1 g/dL; p=0.774) nor change in hemoglobin from admission to delivery (control group: -0.1±1.1 g/dL vs. iron group: 0.4±1.1 g/dL; p=0.232) differed between groups. Women in the control group had shorter length of stay (LOS) median (IQR) than women in the iron group (control group: 7.1 (5.0, 13.7) days; iron group: 11.4 (7.4, 25.9) days; p=0.03). There were no differences in maternal mode of delivery, though each group had high rates of cesarean delivery (control group: 53.7%; iron group: 72.4%; p=0.181). There were no differences in estimated blood loss at delivery (control group: 559±401; iron group: 662.1±337.4;p=0.264) in either group. Neonatal birthweight (control group: 1.9±0.7 kg; iron group: 1.9±0.7 kg; p=0.901), birth hemoglobin (control group: 16.3±2.2 g/dL; iron group: 16±2.2 g/dL; p=0.569), neonatal intensive care unit (NICU) admission (control group: 93.3%; iron group: 84.8%;p=0.272 ), or neonatal death (control group: 8.9%; iron group: 3%; p=0.394) were not different between groups. Conclusions Oral iron administered to anemic inpatient pregnant women was not associated with higher hemoglobin concentrations before delivery. Lack of standardized iron regimens and short hospital stays may contribute to the inefficacy of oral iron for this inpatient pregnant population. The small sample size and retrospective nature of this study are limiting factors in drawing conclusive evidence from this study.

Alternate day versus consecutive day oral iron supplementation in iron-depleted women: a randomized double-blind placebo-controlled study. EClinicalMedicine 2023; 65:102286. [PMID: 38021373 PMCID: PMC10659995 DOI: 10.1016/j.eclinm.2023.102286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 10/04/2023] [Accepted: 10/05/2023] [Indexed: 12/01/2023] Open
Abstract
Background Guidelines to treat iron deficiency recommend daily provision of oral iron, but this may decrease fractional iron absorption and increase side effects. Our objective was to compare consecutive-day versus alternate-day iron supplementation. Methods In a double-masked, randomized, placebo-controlled trial, young Swiss women (n = 150; serum ferritin ≤30 μg/L) were assigned to: daily 100 mg iron for 90 d, followed by daily placebo for another 90 d (consecutive-day group) or the same daily dose of iron and placebo on alternate days for 180 d (alternate-day group). The study period was 24/11/2021-10/8/2022. Co-primary outcomes, at equal total iron doses, were serum ferritin and gastrointestinal side effects; secondary outcomes were iron deficiency and serum hepcidin. Compliance and side effects were recorded daily using a mobile application. Data were analysed using mixed models and longitudinal prevalence ratios (LPR). The trial was registered at ClinicalTrials.gov (NCT05105438). Findings 75 women were assigned to each group and included in the intention-to-treat analysis. Capsule adherence and side effect reporting was >97% in both groups. At equal total iron doses, comparing consecutive-day and alternate-day groups, median serum ferritin was 43.8 μg/L (31.7-58.2) versus 44.8 μg/L (33.8-53.6) (P = 0.98), the LPR for gastrointestinal side effects on days of iron intake was 1.56 (95% CI: 1.38, 1.77; P < 0.0001), and median serum hepcidin was 3.0 nM (IQR 2.0-5.0) versus 1.9 nM (1.4-2.9) (P < 0.0001). Iron deficiency prevalence after 3 months was 5.5% versus 4.3% (P = 0.74) and after 6 months was 11.4% and 3.0% (P = 0.049). Interpretation At equal total iron doses, compared to consecutive day dosing of iron, alternate day dosing did not result in higher serum ferritin but reduced iron deficiency at 6 months and triggered fewer gastrointestinal side effects.

Abstract
Objective For investigating the efficacy and mechanism of Roxadustat + oral iron in the treatment of elderly chronic kidney disease (CKD) complicated with anemia. Methods A total of 100 elderly patients with CKD and anemia admitted to our hospital between April 2020 and December 2021 were enrolled as research subjects, and the patients were assigned to control group (Con group, n = 50) or experimental group (Exp group, n = 50). The patients in the Con group were given oral iron, and those in the Exp group were given Roxadustat capsule based on the Con group. Both groups were given subcutaneous injection of recombinant human erythropoietin. The clinical efficacy, anemia indexes, iron metabolism indexes, inflammatory indexes, and adverse reactions were compared between the two groups. Results The Exp group showed a notably higher treatment effective rate than the Con group (P < 0.05). After treatment, the anemia indexes, iron metabolism indexes, and inflammatory indexes in the Exp group were notably better than those in the Con group (P < 0.05). The Exp group showed a notably lower incidence of adverse reactions during treatment than the Con group (P < 0.05). Conclusion Roxadustat plus oral iron yields a pronounced clinical efficacy in the therapy of elderly patients with CKD and anemia.

Comparison of daily oral iron replacement therapy with every other day treatment in female reproductive age patients with iron-deficiency anemia. Ann Hematol 2022; 101:1459-1464.

Abstract
Iron-deficiency anemia (IDA) is accepted as the most common cause of anemia in the world. The main goals of iron replacement therapy are to normalize the hemoglobin level and to replace iron stores. Current guidelines for treating iron deficiency recommend daily divided doses of iron to increase absorption. Hepcidin is a key regulator of systemic iron balance and acts in harmony with intracellular iron metabolism. Daily dosing and divided doses may increase serum hepcidin and decrease iron absorption. In this study, it was aimed to compare the effectiveness of daily and every other day oral iron replacement therapy in women of reproductive age with iron-deficiency anemia. We included premenopausal female patients aged between 18 and 50 years with iron-deficiency anemia. Forty patients were given oral iron therapy at a daily dose of 2*80 mg (iron sulfate). Forty-three patients were given iron treatment at a dose of 2*80 mg (iron sulfate) every other day. After 2 months of oral iron therapy, there was a significant improvement in hemoglobin, mean corpuscular volume, serum iron, total iron-binding capacity, and transferrin saturation in both groups. The values of hemoglobin, serum iron, transferrin saturation, and ferritin significantly increased at the end of the treatment for both groups. Although the median hepcidin level on the 15th-day measurement in the every other day treatment group was higher than that in the daily treatment group, there was no significant difference. As a result, the patients' compliance with the treatment can be increased by offering treatment every other day instead of daily, since it provides similar treatment effectiveness.

Abstract
BACKGROUND Anemia is an independent risk factor for hospitalization, readmission, prolonged length of stay (LOS), diminished quality of life, and mortality. A multidisciplinary program was implemented to manage anemia preoperatively as a patient blood management (PBM) initiative. METHODS AND MATERIALS From March 2016 to August 2018, 240 patients were screened for anemia during their preoperative cardiovascular visit. About 52/240 (22%) were found to be anemic and met out inclusion criteria. Also, 45/52 (87%) had iron deficiency anemia and 7 (13%) had anemia without iron deficiency. A similar historical cohort of patients undergoing elective cardiovascular surgery with hemoglobin (Hb) < 12 g/dl from September 2014 to February /2016 (n = 52) served as control group. The primary outcome was perioperative red blood cell (RBC) transfusion. Secondary outcomes were date-of-surgery Hb, intensive care unit (ICU) and hospital LOS, complication rates, and transfusion cost. RESULTS The two most common treatments were IV iron ± folate (n = 36/45; 80%) and oral iron (n = 9/45; 20%). As compared to historical patients, study patients had significantly higher day-of-surgery Hb (10.6 ± 1.4 vs. 9.8 ± 1.3 g/dl, p < .001), lower utilization of RBC transfusion (0.86 ± 1.4 vs. 2.78 ± 2.4, p < .001), fewer days in the ICU (2.1 ± 2.0 vs. 4.0 ± 3.5, p = .002), and shorter total LOS (6.9 ± 4.8 vs. 12.9 ± 6.8, p < .0001). Study patients also showed lower overall complication rates (p < .0001). Analysis of RBC acquisition cost and transfusion cost also showed significant saving of 69% ($293 vs. $945 and $656 vs. $2116, respectively). CONCLUSION When corrected for type of procedures and surgeon, our pilot anemia program in elective cardiovascular surgeries showed higher day-of-surgery Hb and significant reduction in RBC transfusion rates, ICU and hospital LOS, and overall complication rates.

Abstract
Iron deficiency (ID) affects people of all ages in many countries. Due to intestinal blood loss and reduced iron absorption, ID is a threat to IBD patients, women, and children the most. Current therapies can efficiently recover normal serum transferrin saturation and hemoglobin concentration but may cause several side effects, including intestinal inflammation. ID patients may benefit from innovative nutritional supplements that may satisfy iron needs without side effects. There is a growing interest in new iron-rich superfoods, like algae and mushrooms, which combine antioxidant and anti-inflammatory properties with iron richness.
