Comparison of the effectiveness of ferrous ascorbate with ferrous sulphate in improving haemoglobin percentage among ante-natal mothers in rural field practice area of a medical college

ABSTRACT Background: Anaemia in pregnancy is defined by the World Health Organisation (WHO) as a haemoglobin concentration of less than 11 g/dl in venous blood. The prevalence of anaemia among ante-natal mothers in India is 50.3%[3]. The government of India supplies ferrous sulphate for prophylaxis and treatment of anaemia among ante-natal mothers for free through the reproductive maternal neonatal and child health + adolescent (RMNCH+A) programme. However, patient compliance is poor due to gastrointestinal disturbances (of all registered pregnancies, less than 1/3 consumed a full course of ferrous sulphate). Previous studies in different settings have shown increased compliance and higher mean haemoglobin levels with ferrous ascorbate, which is more affordable than other commercially available compounds. Objective: Hence, the current study was done to compare the effectiveness of ferrous ascorbate with ferrous sulphate in improving haemoglobin percentage among ante-natal mothers in a rural field practice area of a medical college. Methods: An interventional community-based study was conducted in the rural field practice area of Andhra Medical College. The study was done among 76 registered (registered at Rural Primary Health Centre Simhachalam) ante-natal mothers in gestational age 13–17 weeks with haemoglobin concentration of 7–10.9 g/dl (mild to moderate anaemia) after taking informed consent. The study was performed for two years. Ante-natal mothers who were registered but unavailable during the study period, with a medical history of haematological disorders, chronic cardiac and kidney diseases, known or suspected to have sensitivity to iron compounds, with known thyroid dysfunction or mental illness were excluded from the study. Results: There was a rise in haemoglobin among the entire study population, which was statistically significant (P < 0.0001). There was a higher rise in haemoglobin among the antenatal women who took ferrous ascorbate than among those who took ferrous sulphate (mean difference = 0.344 gm/dl) after 12 weeks of follow-up, which was statistically significant (P = 0.014). Conclusion: The study compared the effectiveness of ferrous ascorbate with ferrous sulphate in improving haemoglobin percentage among antenatal mothers in a medical college’s rural field practice area. There was a significant rise in haemoglobin percentage among the study group, which was on ferrous ascorbate with better compliance and fewer gastrointestinal side effects.

Pathology Deterioration in a Pure β-zero Thalassemia Heterozygote After mRNA COVID-19 Vaccination: A Case Report and Literature Review

Background: β-thalassemia heterozygotes produce sensitive levels of fetal hemoglobin and hemoglobin A2 to remain asymptomatic for life compared to β-thalassemia intermedia and β-thalassemia major patients. The asymptomatic β0 thalassemia minor individuals rarely deteriorate to the point of requiring a blood transfusion. Case report: An asymptomatic individual with a pure β0-thalassemia trait, after his first and only Pfizer modified mRNA COVID-19 injection, immediately developed cardiological, neurological, and other clinically important symptoms. The patient’s severe physical impairments resembled a presyncope (about to feint) syndrome. Multiple hematological tests prior to and after the Pfizer injection revealed that the patient sustained a medically important rise in fetal hemoglobin and concurrently a remarkable drop of his hemoglobin A2 levels, compared to prior to mRNA injection. Moreover, the alterations in his life sustaining fetal hemoglobin and hemoglobin A2 levels was accompanied by a clinically significant lowering of blood hemoglobin concentration that required blood transfusion. The patient’s antibody response to the spike protein remains very high (> 10,000 AU/ml) even almost three years after the Pfizer injection. Furthermore, the elevated levels of C-reactive protein — through May 2024 — after the mRNA injection, apart from pointing to multi-organ systemic inflammation, are consistent with his elevated levels of anti-p53 autoantibodies. Conclusions: The simultaneous decrease of patient blood hemoglobin levels was consistent with the hematological readings of mean corpuscular volume, hematocrit, ferritin, folate, and zinc level deteriorations soon after the mRNA injection, which, apart from his double digit rise in C-reactive protein, resemble overall the pathological manifestations of a β-thalassemia worsening condition. By performing an investigative literature review we conclude that an autoimmune hematological disorder contributed to the patient’s severe hematological stress.

Recombinant erythropoietin for the treatment of iron deficiency anemia in pregnancy: A systematic review.

Treatment options for severe, refractory iron deficiency anemia are limited in pregnancy. To review the available literature on the use of recombinant erythropoietin in the treatment of iron deficiency anemia in pregnancy. An electronic search of seven databases from inception to March 2022 was performed using a combination of keywords. We included all randomized controlled or observational studies of pregnant patients with iron deficiency anemia who received recombinant erythropoietin or control. The primary outcome was a change in hematologic parameters (hemoglobin or hematocrit) after treatment. Studies were appraised using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Data were summarized using narrative synthesis and descriptive statistics as appropriate. This study was registered with PROSPERO, CRD42022313328. Of 234 studies screened, five studies met the inclusion criteria and had sufficient data for analysis (n = 103 recombinant erythropoietin and n = 104 controls). All patients in the intervention group received iron supplementation (intravenous or oral) in addition to recombinant erythropoietin. All patients in the control group received iron supplementation (intravenous or oral) alone. As the result of variance between studies in inclusion criteria, the timing of repeat blood draws, and data reporting, a meta-analysis could not be performed. Three studies found that serial recombinant erythropoietin combined with iron supplementation was more effective at raising hematologic laboratory parameters (hemoglobin or hematocrit) than iron alone. One study reported no difference in hemoglobin or hematocrit levels between groups at day 28. However, patients in this study only received one dose of recombinant erythropoietin, whereas those in the other studies received serial doses. Another study also found no difference in hemoglobin levels by day 28, but patients in the recombinant erythropoietin group had lower hemoglobin levels at baseline and a more rapid rise in hemoglobin than iron alone. This is demonstrated by a more significant rise in hemoglobin at day 11 in the recombinant erythropoietin group than in the control group. Serial recombinant erythropoietin administration and iron supplementation may be more effective at treating refractory iron deficiency anemia in pregnancy than iron supplementation alone.

Ferric carboxymaltose: A game changer in the management of iron deficiency anaemia in pregnancy.

A single-arm prospective cohort (before-after) study among 60 antenatal women with moderate to severe anaemia in the second and third trimesters was conducted from December 2020 to December 2022, and the eligible women were given 1000 mg of intravenous FCM injection. Efficacy was assessed by rate of improvement in haemoglobin and ferritin at 2 weeks post infusion. Safety analysis was done by assessing adverse drug reactions and foetal heart monitoring during the infusion. A total 60 antenatal women with a median gestational age of 32.5 weeks at presentation received 1000 mg of intravenous FCM. There was a rise in mean haemoglobin from 8.05 gm% pre-infusion to 10.93 gm% 2 weeks post infusion, showing a mean rise of 2.88 gm%. Similar improvement was noted in mean serum ferritin levels from 25.92 pre-infusion to 253.96 post FCM infusion. There were no reports of drug-related major adverse effects in the mother or the foetus. FCM is found to be safe and effective treatment with rapid replenishment of haemoglobin and ferritin levels in a single dose, which makes it suitable and compels consideration as the first choice for treatment of iron-deficiency anaemia.

Efficacy of imetelstat on red blood cell (RBC)-transfusion independence (TI) in the absence of platelet transfusions or myeloid growth factors in IMerge.

6566 Background: In the IMerge trial (NCT02598661) of RBC transfusion-dependent (TD) patients (pts) with lower-risk myelodysplastic syndromes (LR-MDS) relapsed/refractory to or ineligible for erythropoiesis stimulating agents, imetelstat showed significant efficacy vs placebo (PBO) for 8-wk, 24-wk, and 1-y TI endpoints, with neutropenia and thrombocytopenia as the most common adverse events (Platzbecker. Lancet 2024). Supportive care was given to all pts as needed, per investigator discretion. Here we report RBC-TI rates in the absence of platelet transfusions or myeloid growth factor use. Separately, RBC-TI with mean central hemoglobin (Hb) rise of ≥1.5 g/d was assessed in all pts. Methods: Pts were randomized 2:1 to receive imetelstat (n=118) 7.5 mg/kg or PBO (n=60) Q4W IV until disease progression. Primary endpoint was 8-wk RBC-TI; 24-wk RBC-TI was a key secondary endpoint. Primary analysis cutoff was Oct 2022, with Oct 2023 cutoff for 1-y RBC-TI analyses. Results: Overall, 21/118 (18%) pts in the imetelstat group and 1/60 (2%) pts in the PBO group needed platelet transfusions; 41/118 (35%) and 2/60 (3%) pts received myeloid growth factors, respectively. Significantly higher percentages of pts achieved 8-wk, 24-wk, and 1-y RBC-TI with imetelstat vs PBO in the absence of either platelet transfusions or growth factor support (Table). In a separate analysis, 8-wk, 24-wk, and 1-y RBC-TI and concurrent Hb rise of ≥1.5 g/dL with imetelstat vs PBO occurred in 28% vs 2%, 23% vs 0%, and 17% vs 0% of pts, respectively (Table). Among responders, imetelstat increased median central Hb levels compared with PBO: 3.6 g/dL vs 0.8 g/dL for 8-wk, 4.2 g/dL vs 1.1 g/dL for 24-wk, and 5.2 g/dL vs 1.7 g/dL for 1-y RBC-TI. Conclusions: Results from this subanalysis confirm that pts who achieve RBC-TI with imetelstat do so without developing severe neutropenia and thrombocytopenia (functionally defined as needing myeloid growth factors or platelet transfusions, respectively), therefore not negating the clinical benefit of the drug. Imetelstat also led to significant rise in Hb levels in RBC-TI responders, particularly long-term responders. These data further support the efficacy of imetelstat in TD pts with LR-MDS.

#2815 Single center, single arm, prospective, observational study of desidustat in chronic kidney disease-induced anemia

Abstract Background and Aims Anemia in chronic kidney disease (CKD) is multifactorial. Relative deficiency of erythropoietin is one of the key reasons for decreased RBC production. This anemia is associated with poor quality of life and increases morbidity in CKD patients. Injectable erythropoietin is the standard of care for CKD-anemia, which has safety concerns. Desidustat, an oral hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), stimulates endogenous erythropoiesis and is approved for CKD anemia treatment. Hence, the present study identifies the real-world clinical efficacy and safety of the desidustat treatment for a short duration in CKD anemia. Method This is an open-label, single-center, prospective study. We analyzed the data of 130 patients who are currently in follow-up and received Desidustat as treatment for CKD-anemia. The study is for the duration of 24 weeks. We followed up on patent at 1 month, 3 months, and the end of the study (6 months). Patients were given a 100-mg Desidustat tablet orally three times in a week. The primary outcome is to assess the change in Hb from baseline, and the secondary outcome is the safety of the therapy. Results In this study, we enrolled 130 patients. Of these 130 patients, 58.4% (n = 76) were male and 41.5% (n = 54) were female. The mean age of the study population was 53.6 ± 12.3 years. The majority of the study population was in the pre-dialysis category; 80% (n = 104) and 20% (n = 26) were on dialysis. All the dialysis patients were on three times per week on Dialysis. Diabetes (68%) and hypertension (75%) are the most common co-morbid conditions in patients with CKD anemia. All the patients received desidustat at a 100 mg, three-weekly dose. During each follow-up visit, a significant rise in hemoglobin was observed (p<0.001), as shown in the figure. With desidustat therapy, adverse drug reactions were seen in 5.3% (n = 7) cases: three cases of abdominal pain, two cases of vomiting, and two cases of diarrhea. Conclusion Oral HIF-PHIs and Desidustat showed significant improvement in hemoglobin in CKD anemia patients. More studies require for safety and efficacy in Dialysis dependent CKD - Anemia patients.

Comparison of Iron-Supplementation Versus Combination of Vitamin-A & Iron-supplementation in Childhood Iron Deficiency Anaemia

Background and Objectives: childhood anemia is highly prevalent worldwide and its effective treatment is the cornerstone to improve health of these children. This study was conducted to compare the mean rise in haemoglobin (Hb) after iron-alone versus the combination of vitamin-A & iron supplementation in childhood iron-deficiency anemia.Methods: This randomized controlled trial was done at Paediatrics Medicine Department, Jinnah Hospital, Lahore from January-2019 to June-2019. A total of 60 cases, as per inclusion criteria were enrolled from the Paediatric Medicine Department of Jinnah Hospital Lahore. Group-A was supplemented with a combination of vitamin-A and iron while Group-B patients were supplemented with Iron alone. Hb was checked at baseline and after 3 months of treatment as per the designated group. All information, as per predesigned proforma, was entered and interpreted using SPSS version 23.0. An Independent sample t-test was applied and a p-value < 0.05 was considered statistically significant.Results: Sixty patients were included, keeping 30 in each group i.e. Group-A (Vitamin-A + Iron) & Group-B (Iron-alone). In both groups, most of the patients were male, i.e. 22(73.3%) and 23(76.7%) in group-A and group-B respectively. In group-A, the mean age was 1.96±1.6 years while 2.12±1.5 years in group-B. In group-A, the mean rise in Hb level after 3-months of treatment was 3.0±0.99 g/dl, on the other hand, it was 1.96±1.00 g/dl in group B, with a p-value of 0.00014.Conclusion: Vitamin-A supplementation combined with iron replacement therapy is recommended for substantial improvement among children with iron deficiency anemia.Keywords: Vitamin-A, Iron-Supplementation, Hemoglobin (Hb), Iron Deficiency Anemia (IDA).

Mitapivat: New dawn in pyruvate kinase deficiency and beyond

Mitapivat is the first in class oral allosteric activator of pyruvate kinase enzyme, leading to increased ATP production. Since red blood cells (RBC) rely on anaerobic metabolism, converting phosphoenolpyruvate to pyruvate in Embden– Meyerhof glycolytic pathway is the most important step for ATP production. Deficiency of ATP in patients with pyruvate kinase deficiency (PKD) leads to the destruction of RBCs. In hemoglobinopathies, including thalassemia and sickle cell disease, increased stress and utilization leads to rapid depletion of ATP resources.Phase II DRIVE PK study was the first randomized controlled trial that showed benefits in adult patients without regular transfusion requirement in regards to a rise in hemoglobin ≥1.0 g/dl and improvement in other parameters of hemolysis even with a low 50 mg twice daily dose. Minor adverse effects, including headache, insomnia, and nausea were reported.Subsequent adult studies like ACTIVATE III (non-transfusion-dependent) and ACTIVATE III – T (transfusion-dependent) in patients with PKD showed sustained hemoglobin response in 16/40 (40%) patients. It was tolerated well, and the adverse effect profile was similar to the previous study except for hypertriglyceridemia and hypertension in two patients.Phase I/II trials on patients with thalassemia and sickle cell anemia have also shown promising results in reducing transfusion burden and other disease-related co-morbidities, paving the way for further studies.Mitapivat appears to be a safe, well-tolerated, and effective drug for PKD and other RBC pathologies in adults. Results of ongoing pediatric studies in these settings are awaited to reveal its safety profile in children.

Does Increasing Haemoglobin At High Altitude Alone Cause A Rise In Coronary Artery Disease; A Prospective Study

Objective: To study the effect of high altitude on haemoglobin concentration with coronary artery disease. Study Design: Prospective longitudinal study. Place and Duration of Study: Combined Military Hospital, Skardu Pakistan, from Jan to Dec 2018 Methodology: All individuals working at high altitudes diagnosed with coronary artery disease (CAD) were included. Haemoglobin concentration was measured by doing a complete blood picture. Results: The total number of patients diagnosed with coronary artery disease in the study was 34 (all males). 16(47%) of the patients with coronary artery disease were evacuated from the height of 8000 to 13000 feet, 16(47%) from the height of 13001 to 18000 feet and 2(6%) patients were evacuated from the height of more than 18000 feet. The mean haemoglobin (Hb) of patients evacuated from the height of 8000 to 13000 feet was 15.7±1.4gm/dl; of patients evacuated from a height of 13001 to 18000 feet was 16.3±1.5gm/dl, and of patients evacuated from more than 18000 feet was 18.3±1.2gm/dl. Conclusion: Persistent rise in haemoglobin was noted with increasing altitude. However, most of the patients with coronary artery disease were from a height of 13000 to 18000 feet.

Mean Rise in Hemoglobin After Intravenous Iron Therapy in Children with Iron Deficiency Anemia

Introduction: Iron deficiency anemia (IDA) is a significant public health issue in Pakistan, affecting up to 63% of children, as revealed by the Pakistan National Nutritional Survey 2018. While oral iron remains the primary choice, challenges in compliance have led to the consideration of intravenous (IV) iron therapy, particularly iron sucrose. The study discusses the safety and efficacy of IV iron therapy in Pakistani children and aims to broaden our understanding of treating IDA in resource-constrained regions. Aims & Objectives: To determine the average hemoglobin (Hb) increase in iron-deficient-anemic children aged 01 to 12 years after treatment with intravenous iron sucrose. Place and Duration of Study: A quasi-experimental study was undertaken at Fauji Foundation Hospital in Rawalpindi, spanning from September 2021 to September 2022. Material & Methods: The study focused on a cohort of pediatric patients aged between 1 and 12 years, all of whom were diagnosed with iron deficiency anemia and had previously encountered ineffective outcomes with oral iron therapy. In this investigation, the patients received treatment involving intravenous iron sucrose. Subsequently, their progress was diligently monitored after a period of 8 weeks. Improvement in hemoglobin level was assessed at the end of treatment to evaluate its efficacy.Data processing and statistical analysis were carried out using SPSS version 23,p-value of <0.05 indicated statistical significance. Results: Out of 150 study cases, 96 (64.0 %) were male, while 54 (36.0 %) were female. The mean age of our study cases was 05 ± 2.3 years of these 150 study cases, 74 (49.3 %) belonged to rural areas, and 76 (50.7 %) belonged to urban areas. Poor socioeconomic status was noted in 97 (64.7 %), and 53 (35.3%) were middle-income. A family history of iron deficiency anaemia was recorded in 16 (10.7%). Iron deficiency due to dietary iron insufficiency was reported in 67 (44.7%), Total Parentral Nutrition (TPN) dependencywas seen in 61 (40.7%) and 22 (14.7%) had chronic gastritis. The mean baseline (pretreatment) haemoglobin level was 7.71 ± 0.63 g/dl, while the mean post-treatment haemoglobin level was 10.68 ± 0.60 g / dl (p = 0.001). Conclusion: After intravenous iron sucrose, we noted a significant rise in paediatric patients' hemoglobin levels, emphasizing its effectiveness and safety. Statistically, we found correlations with age, family history, and causes. Healthcare practitioners should consider injectable iron treatments for better results and reduced health issues in this group.

The Effect of Uterine Artery Embolization on Heavy Menstrual Bleeding in Patients with Leiomyomata

Objective: To compare the effect of uterine artery embolization and medical management on heavy menstrual bleeding in patients managed for uterine fibroids. Study Design: Comparative Cross-sectional Study. Place and Duration of Study: The study was conducted at the Department of Gynecology and Obstetrics, Pak Emirates Military Hospital (PEMH) Rawalpindi, Pakistan fromAugust 2021 to March 2023.Methods: Women between the ages of 35 and 50 years who presented with heavy menstrual bleeding and were diagnosed with leiomyomata were included in this study. They were divided into two groups via block randomization. Group-I underwent uterine artery embolization while group-II received medical treatment (gonadotropin-releasing hormone (GnRH) antagonist). Clinical factors like shrinkage in the size of fibroids, rise in hemoglobin levels, and pelvic pain scores were compared in both groups at the end of three months. Results: Out of 160 women recruited in the study, 52 (32.5%) were pre-menopausal, while 108 (67.5%) were peri menopausal. The mean age of patients who presented with heavy menstrual bleeding due to leiomyomata was 45.23 ±12.70 years. The mean rise in hemoglobin (p-value-0.007) and mean shrinkage size (p-value<0.001) were statistically significantly found more in patients who underwent uterine artery embolization as compared to those who took medical treatment. The mean pain score (p-value-0.01) was also found to be more in a group of patients who underwent uterine artery embolization.Conclusion: Uterine artery embolization emerged as an effective procedure for women managed for heavy menstrual bleeding due to uterine fibroids. Medical management via gonadotropin-releasing hormone (GnRH) antagonist was inferior in efficacy in terms of mean rise in hemoglobin and fibroid shrinkage.How to cite this: Khan S, Ahmad M, Mirza ZA, Sheraz A, Tariq M.

Clinical effectiveness of ferric carboxymaltose (iv) versus iron sucrose (iv) in treatment of iron deficiency anaemia in pregnancy: A systematic review and meta-analysis.

Iron deficiency anaemia (IDA) during pregnancy is treated with oral and parenteral iron. The objective of this review was to compare the clinical effectiveness, safety, pregnancy and neonatal outcomes of intravenous (iv) ferric carboxymaltose (FCM) and iv iron sucrose (IS) in treating IDA in pregnancy. The Department of Health Research funded this study. PubMed, Cochrane Library, EMBASE and Scopus were searched to include studies published till November 2022. The protocol was registered in PROSPERO (CRD42022306092). Pregnant women (15-49 yr) in second and third trimesters, diagnosed with moderate-to-severe iron deficiency anaemia, treated with either of the drugs were included. The included studies were critically assessed using appropriate tools. We conducted a qualitative synthesis of the studies and meta-analysis for improvement in haematological parameters and incidence of adverse events. A total of 18 studies were included. The risk of bias was low to moderate. A rise in haemoglobin up to four weeks was higher with FCM than IS by 0.57 (0.24, 0.9) g/dl. Intravenous FCM is associated with fewer adverse events than IS [pooled odds ratio: 0.5 (0.32, 0.79)]. The included studies had limited evidence on pregnancy and neonatal outcomes after iv iron treatment. Intravenous FCM is effective and safer than intravenous IS in terms of haematological parameters, in treating IDA in pregnancy. Further research is required on the effects of iv FCM and iv IS on the pregnancy and neonatal outcomes when used for treating IDA in pregnancy.

Effect of recombinant human erythropoietin combined with iron sucrose on postoperative hemoglobin in patients undergoing artificial joint replacement

With the aging of the population, an increasing number of elderly patients are opting for artificial joint replacement, leading to the exploration of various rapid rehabilitation programs in the perioperative period. In this study, we aimed to investigate the effectiveness of combining recombinant human erythropoietin and iron sucrose in altering the range and trend of postoperative hemoglobin in patients undergoing arthroplasty. Specifically, we will examine whether this combination can effectively alter the rise and fall of postoperative haemoglobin, identify the inflection point of haemoglobin change or recovery after arthroplasty, and assess the effect of treatment on serum iron in postoperative blood. We conducted a retrospective study of 138 patients who underwent unilateral total joint arthroplasty by the same surgeon in the same hospital before July 2022. The results of this study may provide valuable insights for the development of effective rehabilitation programs for patients undergoing arthroplasty.

Intravenous Iron Therapy in Severe Anemia at 28-34 Weeks of Gestation and it’s Feto-Maternal Outcome- A Prospective Study from A Developing Country

Introduction: Iron deficiency anaemia (IDA) is the most common nutritional deficiency in pregnancy. Anemia results in poor pregnancy outcome and also affects fetal outcome. This study was undertaken to evaluate the response of intravenous iron given to pregnant women with severe IDA and their feto-maternal outcome.
 Methodology: A prospective study was conducted in the department of Obstetrics & Gynaecology, at a tertiary care centre of Northern India. Fifty-two pregnant women with haemoglobin between 5-7 g% with diagnosed iron deficiency attending antenatal clinic were given intravenous iron complex Follow-up after 4 weeks was done and IDA specific blood profile was done at baseline and at follow-up. Feto-maternal outcomes were seen at delivery.
 Results: The mean age of study population was 25.5 ± 3.96 yrs. Improvement at 4 week follow-up from baseline in hemoglobin (p value-0.001) and iron profiles (S. Iron, Total Iron Binding Capacity (TIBC), S. Ferritin) (p value -0.0001) were highly significant. On comparing the Hb levels at delivery after intravenous infusion at 28-34 weeks gestation, 17 patients were still below 8 gm%, whereas 35 were above 8 gm%. Distribution of IUGR, preterm labor and blood transfusion in postpartum period were statistically significant amongst both group (p value<0.05). Fetal outcomes were also evaluated amongst the 2 groups. Distribution of Preterm birth, birth weight and NICU admission was also statistically significant (p value<0.05).
 Conclusion: The intravascular iron therapy definitely has a rapid increase in haemoglobin which can prevent the complications due to severe anaemia in pregnancy and blood transfusion can also be prevented, but iron stores are not replenished to the optimum level, so there is a need to give replacement therapy (by oral route) post transfusion for long term benefits. The rise of hemoglobin affects feto-maternal outcomes even in the last trimester.contrast agents. This is a first case report of AHCM portrayed by this ingenious technology.

Erythropoietin downregulates red blood cell clearance, increasing transfusion efficacy in severely anemic recipients.

Red blood cells (RBC) transfusion is used to alleviate symptoms and prevent complications in anemic patients by restoring oxygen delivery to tissues. RBC transfusion efficacy, that can be measured by a rise in hemoglobin (Hb) concentration, is influenced by donor-, product-, and recipient-related characteristics. In some studies, severe pre-transfusion anemia is associated with a greater than expected Hb increment following transfusion but the biological mechanism underpinning this relationship remains poorly understood. We conducted a prospective study in critically ill patients and quantified Hb increment following one RBC transfusion. In a murine model, we investigated the possibility that, in conjunction with the host erythropoietic response, the persistence of transfused donor RBC is improved to maintain a highest RBC biomass. We confirmed a correlation between a greater Hb increment and a deeper pre-transfusion anemia in a cohort of 17 patients. In the mouse model, Hb increment and post-transfusion recovery were increased in anemic recipients. Post-transfusion RBC recovery was improved in hypoxic mice or those receiving an erythropoiesis-stimulating agent and decreased in those treated with erythropoietin (EPO)-neutralizing antibodies, suggesting that EPO signaling is necessary to observe this effect. Irradiated recipients also showed decreased post-transfusion RBC recovery. The EPO-induced post-transfusion RBC recovery improvement was abrogated in irradiated or in macrophage-depleted recipients, but maintained in splenectomized recipients, suggesting a mechanism requiring erythroid progenitors and macrophages, but which is not spleen-specific. Our study highlights a physiological role of EPO in downregulating post-transfusion RBC clearance, contributing to maintain a vital RBC biomass to rapidly cope with hypoxemia.

Laparoscopic minigastric bypass as a revisional choice for failed restrictive bariatric procedure and its metabolic impact

Background Restrictive bariatric procedures, like laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG), are associated with an increased risk of long-term failure. The efficacy of One-anastomosis gastric bypass (OAGB) has been described in primary and revisional settings, with a lack of Egyptian studies regarding OAGB as a revisional surgery. Herein, we describe our experience regarding 1-year outcomes of OAGB as a revisional surgery after failed LSG or LAGB. Patients and methods Fifty patients with failed LSG or LAGB were enrolled in this prospective study. All cases underwent laparoscopic OAGB, and its effects on weight loss and obesity-related comorbidities were noticed after 3, 6, and 12 months. Results The duration of the operation ranged between 45 and 120 min Postoperative complications included leakage (2%), hemorrhage (2%), and port site infection (2%). OAGB as a revisional surgery led to a significant and effective weight loss, as the percent of excess weight loss (%EWL) had mean values of 23.72%, 51.54%, and 80.25% at the scheduled visits, respectively. The procedure was associated with a significant rise in hemoglobin and albumin, significant decline in blood sugar, glycosylated hemoglobin, vitamin B12, and most lipid profile parameters, with no significant changes in serum calcium and high-density lipoproteins. Beneficial effects (remission or improvement) were noticed in 88.9% of diabetic cases, 80% of hypertensive cases, and 100% of reflux cases at one-year follow-up visit. Conclusion Laparoscopic OAGB as a revisional surgery is a safe and efficacious procedure in the management of patients with failed previous restrictive procedures like LSG and LAGB.

Parvovirus B19 infection after kidney transplantation: A single centre experience

BackgroundParvovirus B19 is an uncommon cause of anaemia in kidney transplant recipients (KTRs). The study aims to determine the incidence, clinical presentation, laboratory findings and outcome of parvovirus B19-related anaemia in KTR. MethodWe conducted a 12-year retrospective, single-centre study describing the clinical profile of KTRs with parvovirus B19-related anaemia. ResultAmongst the 714 patients who underwent kidney transplantation between January 2011 and January 2023, (cumulative follow-up: 1287 patient-years), six females and one male, developed parvovirus B19-related anaemia. The incidence proportion (risk) is 0.98% with an incidence rate of 5.43 cases per 1000 patient-year. The median duration from transplant to development of anaemia was 6 weeks (range: 4–40 weeks). The mean fall in haemoglobin was 2.88 ± 1.55 gm/dl; concomitant leukopenia and thrombocytopenia were observed in 57.1 and 28.6% of patients. Three patients responded to a reduction in immunosuppression, the four non-responders required the administration of low-dose intravenous immunoglobulin. The mean duration from initiation of therapy to a sustained rise in haemoglobin was 7.71 ± 2.62 weeks. None of the patients had a relapse of the infection. ConclusionsParvovirus B19 infection is an uncommon cause of post-transplant refractory anaemia. The key to successfully managing such patients includes a high index of suspicion, early diagnosis and reduction of immunosuppression with or without administration of intravenous immunoglobulin.

Long-term clinical efficacy and safety of thalidomide in patients with transfusion-dependent β-thalassemia: results from Thal-Thalido study

Regular blood transfusion is the mainstay of treatment in transfusion-dependent β-thalassemia (TDT); however, transfusions culminate in an array of serious complications. Therefore, a single-arm, non-randomized clinical trial was conducted in hydroxyurea refractory TDT patients to explore the long-term safety and efficacy of thalidomide. The primary outcomes for efficacy were rise in hemoglobin (Hb) level and changes in transfusion frequency. Whereas, several clinical and laboratory parameters were assessed for safety of thalidomide. Secondary outcomes included changes in serum ferritin, serum lactate dehydrogenase (LDH), serum uric acid, red blood cell indices, and size of liver and spleen. A total of 532 patients were followed for a period of 30 months. Significant increase in mean Hb level was identified at 6 months (1.4 g/dL, p ≤ 0.001) and 30 months (2 g/dL, p ≤ 0.001) in comparison with baseline. A total of 408 (76.7%) patients responded to thalidomide therapy (excellent responders 25.8%, good responders 31%, and partial responders 19.9%) and attained transfusion independence within 6 months of therapy. A significant decline in mean ferritin, LDH level, liver size, and spleen size was observed. No unfavorable effects were observed on kidney and liver functions. Mild adverse events were reported in 48 (9%) patients and serious adverse events, including cerebral vascular accident and portal vein thrombosis were reported in two patients each. This study concludes that thalidomide is an effective and well-tolerated drug that can improve Hb levels and reduce transfusion burden in hydroxyurea refractory TDT patients.Trial registration: This trial is registered at http://www.clinicaltrial.gov as # NCT03651102.

Less major bleeding and higher hemoglobin after left atrial appendage closure in high-risk patients: Data from a long-term, longitudinal, two-center observational study.

Left atrial appendage closure (LAAC) is a mechanical alternative for stroke prevention in patients at risk who cannot tolerate oral anticoagulation (OAC). Our hypothesis was that the reduction of anticoagulation following LAAC results in a decrease of bleeding events and a rise in serum hemoglobin in a high-risk collective of patients with atrial fibrillation (AF). Bleeding events, use of erythrocyte concentrates, anticoagulation, embolic events, and serum hemoglobin levels before and following LAAC were compared over more than 4 years. Seventy-five patients (CHA₂DS₂-VASc score 4.4 ± 1.7, HAS-BLED score 4.6 ± 1.1) were analyzed. Before LAAC (observation period 1.8 ± 1.8 years), 67 patients experienced 1.8 ± 1.4 bleeding events (0.9 ± 1.3 major) per year resulting in 0.7 ± 1.3 transfusions per year. After LAAC (2.6 ± 2.0 years), 26 patients (p < .0001 vs. before) had 0.6 ± 2.1 bleeding events (p < .0001), 0.2 ± 0.6 major bleedings (p < .0001) and received 0.6 ± 1.9 transfusions per year (p = .671). Fourteen patients had stroke before and 3 after LAAC (p = .008). Serum hemoglobin increased from initially 9.9 ± 3.0to 11.9 ± 2.3 g/dL until the end of follow-up (p = .0005). Adverse embolic events did not differ before and after LAAC in our collective. In this clinical relevant cohort of AF patients with high risk for stroke and intolerance to OAC, we show that LAAC was able to reduce the rate of stroke and bleeding events, which translated into a rising serum hemoglobin concentration.

Effect of Recommended Dietary Intake versus Higher Doses of Supplemental Zinc on Iron and Copper Deficiency Anemia Among Patients with Chronic Kidney Diseases, A Double-Blinded, Randomized Clinical Trial

Background: Complex interplays happen in absorption and function of iron, zinc and copper. Both zinc deficiency and excess may lead to anemia. In Iran, commonly available supplements for chronic kidney disease (CKD) patients contain 25 mg-zinc (Zn). This study compared 25 mg versus 7.5 mg dose of zinc in anemia of CKD patients, the latter dose approximates to recommended dietary intake (RDI) of zinc. Methods: In this double-blinded clinical trial, 51 non-dialysis CKD patients were randomized to continue previous formulation (25 mg-Zn group) or change to a new preparation (7.5 mg-Zn group) for three months. Blood counts and serum iron, zinc and copper status were compared between and within the groups. Results: At the end of the study, serum copper and ceruloplasmin concentrations were significantly higher in 7.5 mg-Zn group compared with those in 25 mg-Zn arm (115.04± 23.05 vs. 102.48±14.98 µg/dL; P= 0.02 and 29.97±7.94 vs. 25.42±4.23 mg/dL; P= 0.01, respectively). Serum zinc levels did not differ between two groups (76.73±15.35 vs. 77.68±18.07 µg/dL for 7.5 mg-Zn and 25 mg-Zn groups, respectively; P= 0.84). After three months, patients in 7.5 mg-Zn group experienced increase in their Hb (11.11±1.17 vs. 10.72±1.03 g/dL; P= 0.04), HCT (35.28± 4.01 vs. 33.96± 3.74%; P= 0.03), MCV (86.30 (81.40-90.82) vs. 86.00 (80.35-88.77) ¦L; P= 0.01) and ferritin (202.60 (79.29-298.97) vs. 129.07 (42.25-225.87) ng/mL; P&lt;0.001) compared to their baseline values. Conclusion: Reducing zinc content to its RDI value in supplement for CKD patients led to increased serum copper and ceruloplasmin concentrations. Moreover, patients who switched to RDI zinc-containing formula experienced a significant rise in blood hemoglobin. hematocrit, mean corpuscular volume (MCV), and ferritin concentration.
