Rare presentations of small bowel endometriosis.

Despite endometriosis being a relatively common chronic gynecological condition in women of childbearing age, small bowel endometriosis is rare. Presentations can vary from completely asymptomatic to reported symptoms of abdominal pain, bloating, and diarrhea. The following two cases depict very atypical manifestations of ileal endometriosis that presented as obscure intermittent gastrointestinal bleeding and bowel obstruction requiring surgical intervention. The first case describes a previously healthy 40-year-old woman with severe symptomatic iron deficiency anemia and intermittent melena. A small bowel enteroscopy diagnosed multiple ulcerated strictures in the distal small bowel as the likely culprit. Despite nonsteroidal anti-inflammatory drug-induced enteropathy being initially considered as the likely etiology, histopathological examination of the resected distal ileal segment revealed evidence of endometriosis. The second case describes a 66-year-old with a presumptive diagnosis of Crohn's disease who reported a 10-year history of intermittent perimenstrual abdominal pain, diarrhea, and nausea with vomiting. Following two subsequent episodes of acute bowel obstruction and surgical resection of the patient's stricturing terminal ileal disease, histopathological examination demonstrated active chronic inflammation with endometriosis. Small bowel endometriosis should be considered as an unusual differential diagnosis in women who may present with obscure gastrointestinal bleeding from the small bowel or recurrent bowel obstruction.

Acquired Thrombotic Thrombocytopenic Purpura (TTP) Presenting With Synthetic Cannabinoid Use.

Synthetic cannabinoids (SCs) have become commercially available throughout the United States as manufacturers circumvent regulations with labels stating "not for human consumption" with misleading advertisements, resulting in the consumption of products that are not safe or regulated. We present a case report of a middle-aged woman exhibiting altered mental status secondary to SC use who was found to have severe thrombocytopenia and hemolytic anemia. She was later confirmed to have thrombotic thrombocytopenic purpura (TTP) through ADAMTS13 testing. TTP is one of several platelet-related disorders presenting with findings of hemolytic anemia and thrombocytopenia. The presence of altered mental status is typically used as a symptomatic differentiator between hemolytic uremic syndrome, immune thrombocytopenic purpura, and TTP. SCs can cause superimposed altered mental status, which, in the setting of a concomitant platelet disorder, can complicate the standard workup and prolong the time to a final diagnosis. This case serves as an essential reminder that collecting detailed social history and promptly recognizing laboratory abnormalities is critical for early recognition of TTP, as the diagnosis is time-sensitive and delays in recognition can lead to significant morbidity and mortality.

Anemia Prevalence and Socioeconomic Status among Adolescent Girls in Rural Western India: A Cross-Sectional Study.

Background: Anemia poses a significant challenge among Indian adolescent girls due to their heightened vulnerability, resulting from increased micronutrient requirements, rapid physical growth, menstrual blood loss, inadequate nutrition, and socioeconomic disparities. This study sought to evaluate the prevalence of anemia, along with socioeconomic and nutritional statuses among adolescent girls attending rural public schools in Pune, India. Methods: A sample of 400 girls was selected from 22 villages through Symbiosis International University. Hemoglobin levels were assessed using the HemoCue 201 system, while standardized protocols were employed for height, weight, and BMI-for-age measurements. Socioeconomic status was determined using the Kuppuswamy scale. Results: The findings revealed an overall anemia prevalence of (42.75%), comprising severe (2.5%), moderate (21%) and mild (20.25%) cases. Additionally, a substantial proportion (74.6%) of girls were classified as underweight. Socioeconomic analysis disclosed that 64.25% of families belonged to the lower middle class, and 27% in the upper lower class. Anemia was more prevalent in young adolescent girls (10-14 years) and in the families of adolescents who had low income, were illiterate, unemployed, and belonged to the lower-middle class and upper-lower-class socio-economic status (SES) and did not have a bank account. Conclusion: Anemia was prevalent in adolescent girls and associated with low SES. This study underscores the limitations of relying solely on the distribution of iron and folic acid tablets to combat anemia. A holistic strategy is imperative, encompassing improvements in SES of families (literacy, employment and income), as well as initiatives aimed at enhancing the nutritional status of adolescent girls.

Iron and bones: effects of iron overload, deficiency and anemia treatments on bone.

Iron is a vital trace element and exerts opposing effects on bone in both iron overload and iron deficiency situations. Remarkably, iron supplementation through intravenous infusion in patients with iron deficiency can also have detrimental effects on bone in special cases. The diverse mechanisms underlying these effects and their manifestations contribute to the complexity of this relationship. Iron overload impacts both bone resorption and formation, accelerating bone resorption while reducing bone formation. These effects primarily result from the direct action of reactive oxygen species (ROS), which influence the proliferation, differentiation, and activity of both osteoclasts and osteoblasts differently. This imbalance favors osteoclasts and inhibits the osteoblasts. Simultaneously, multiple pathways, including bone morphogenic proteins, RANK ligand, and others, contribute to these actions, leading to a reduction in bone mass and an increased susceptibility to fractures. In contrast, iron deficiency induces low bone turnover due to energy and co-factor deficiency, both of which require iron. Anemia increases the risk of fractures in both men and women. This effect occurs at various levels, reducing muscular performance and, on the bone-specific level, decreasing bone mineral density. Crucially, anemia increases the synthesis of the phosphaturic hormone iFGF23, which is subsequently inactivated by cleavage under physiological conditions. Thus, iFGF23 levels and phosphate excretion are not increased. However, in specific cases where anemia has to be managed with intravenous iron treatment, constituents-particularly maltoses-of the iron infusion suppress the cleavage of iFGF23. As a result, patients can experience severe phosphate wasting and, consequently, hypophosphatemic osteomalacia. This condition is often overlooked in clinical practice and is often caused by ferric carboxymaltose. Ending iron infusions or changing the agent, along with phosphate and vitamin D supplementation, can be effective in addressing this issue.

Dual role of proliferating cell nuclear antigen monoubiquitination in facilitating Fanconi anemia-mediated interstrand crosslink repair.

The Fanconi anemia (FA) repair pathway governs repair of highly genotoxic DNA interstrand crosslinks (ICLs) and relies on translesion synthesis (TLS). TLS is facilitated by REV1 or site-specific monoubiquitination of proliferating cell nuclear antigen (PCNA) (PCNA-Ub) at lysine 164 (K164). A PcnaK164R/K164R but not Rev1-/- mutation renders mammals hypersensitive to ICLs. Besides the FA pathway, alternative pathways have been associated with ICL repair (1, 2), though the decision making between those remains elusive. To study the dependence and relevance of PCNA-Ub in FA repair, we intercrossed PcnaK164R/+; Fancg-/+ mice. A combined mutation (PcnaK164R/K164R; Fancg-/- ) was found embryonically lethal. RNA-seq of primary double-mutant (DM) mouse embryonic fibroblasts (MEFs) revealed elevated levels of replication stress-induced checkpoints. To exclude stress-induced confounders, we utilized a Trp53 knock-down to obtain a model to study ICL repair in depth. Regarding ICL-induced cell toxicity, cell cycle arrest, and replication fork progression, single-mutant and DM MEFs were found equally sensitive, establishing PCNA-Ub to be critical for FA-ICL repair. Immunoprecipitation and spectrometry-based analysis revealed an unknown role of PCNA-Ub in excluding mismatch recognition complex MSH2/MSH6 from being recruited to ICLs. In conclusion, our results uncovered a dual function of PCNA-Ub in ICL repair, i.e. exclude MSH2/MSH6 recruitment to channel the ICL toward canonical FA repair, in addition to its established role in coordinating TLS opposite the unhooked ICL.

[Current trends in the treatment of aplastic anemia].

Aplastic anemia is a syndrome characterized by reduced hematopoietic stem cells, bone marrow hypoplasia, and pancytopenia, and is often considered a T-cell-mediated autoimmune disease. It is predominantly treated with hematopoietic stem cell transplantation and immunosuppressive therapy with anti-human thymocyte immunoglobulin (ATG) and cyclosporine. Only rabbit ATG was previously available in Japan, but equine ATG was recently approved for use in 2023. Thrombopoietin receptor agonists available in Japan are oral eltrombopag and injectable romiplostim. In hematopoietic stem cell transplantation for aplastic anemia, a conditioning regimen of reduced-dose cyclophosphamide and fludarabine has been used to reduce cardiotoxicity. Human leukocyte antigen haploidentical stem cell transplants have also been developed, and their use in patients without a donor is increasingly reported. Future advancements in novel drugs and transplantation therapies could revolutionize the management of aplastic anemia.

The German sickle cell disease registry reveals a surprising risk of acute splenic sequestration and an increased transfusion requirement in patients with compound heterozygous sickle cell disease HbS/ß-thalassaemia and no or low HbA expression.

Patients with sickle cell disease (SCD) in Germany exhibit a substantial genetic diversity in the ß-globin genotype. Data collected by the national German SCD registry reflect this diversity and allowed us to analyze the phenotypes associated with different SCD genotypes. Our study focused on 90 patients with HbS/ß-thalassaemia (HbS/ß-thal) and compared these to patients with HbSS and HbSC. Patients with HbS/ß-thal were classified into three groups: HbS/ß0-thal (no HbA), HbS/ß+-thal (HbA < 14%), and HbS/ß++-thal (HbA≥14%). In comparison to HbSS, patients with HbS/ß++-thal had higher Hb-levels, lower hemolytic activity and rarely required red blood cell transfusions. HbS/ß0-thal and HbS/ß+-thal closely resembled each other and are jointly referred to as HbS/ß0/+-thal. Compared to HbSS, patients with HbS/ß0/+-thal experienced a similar frequency of vasoocclusive crises and degree of hemolysis. However, the frequency of red blood cell transfusions (0.6 vs. 0.39/year, p = .0049) and splenic sequestration crises (42.4 vs. 15.5% of patients, p = 3.799e-05) was higher in HbS/ß0/+-thal than in HbSS, but close to zero in HbS/ß++-thal. In conclusion, the level of HbA expression determines the phenotype of HbS/ß+-thal. HbS/ß-thal expressing no or little HbA is hematologically similar to HbSS, but causes a previously unknown high risk of splenic sequestration.

Outcomes in transcatheter aortic valve replacement (TAVR) patients requiring red blood cell transfusion: A nationwide perspective.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) can be complicated by anemia due to periprocedural bleeding, hemolysis, vascular events, or significant bleeding associated with antiplatelet therapy. OBJECTIVE: We used the National Inpatient Sample (NIS) database to study the outcomes of patients who underwent TAVR and developed significant anemia requiring red blood cell (RBC) transfusion. METHODS: This is a retrospective cohort study utilizing the NIS database from 2016 to 2017. We identified patients who underwent TAVR and required RBC transfusion using ICD-10 and PCS-10 codes. The primary outcome was all-cause inpatient mortality, and the secondary outcomes were the cost of hospitalization and length of stay (LOS). Student t-test, Chi-square, and ANOVA were utilized for statistical analysis where applicable. Multivariate logistic regression was used to adjust for potential confounders. STATA 15.0 was utilized for data analysis. RESULTS: A total of 18,325 patients underwent TAVR in 2016-2017. Among them, 6.7 % of patients required RBC transfusion. Patients were relatively older in the transfusion group (81 yrs vs 79 yrs; p < 0.001). The mean cost of hospitalization was higher in the transfusion group (283,153 USD vs 208,939 USD; p < 0.001). The mean length of stay (LOS) was higher in the transfusion group (9.0 days vs 4.3 days; p < 0.001). Patients in the transfusion group had higher inpatient all-cause mortality compared to patients without transfusion (6.1 % vs 1.3 %; odds ratio 4.94; p < 0.001, 95 % CI 3.7-6.4). Inpatient mortality and LOS didn't differ by race or sex in the transfusion group. All-cause mortality, LOS, and cost of hospitalization were independently increased by transfusion after adjusting for potential confounders i.e. sex, race, hospital teaching status, hospital region, heart block, pacemaker, arrhythmias, heart failure, diabetes, pulmonary hypertension, CKD, and others using multivariate logistic regression. CONCLUSION: In patients undergoing TAVR, blood transfusion was associated with adverse outcomes including increased mortality, length of stay, and cost of hospitalization. The role of careful patient selection, judicious use of antiplatelets, anticoagulants, and pre-procedural optimization of anemia needs further investigation to optimize patient outcomes.

[Diagnosis and treatment of iron deficiency anemia].

The causes of iron deficiency anemia include blood loss, increased demand, insufficient dietary intake, and disorders affecting iron absorption. In certain circumstances, atrophic gastritis, either autoimmune or due to Helicobacter pylori infection, may contribute. On very rare occasions, iron-refractory iron deficiency anemia can develop as a consequence of TMPRSS6 mutations. Iron deficiency anemia is diagnosed by identification of microcytic hypochromic anemia with low serum ferritin levels. In cases of chronic disorders such as chronic kidney disease, chronic heart failure, and chronic inflammatory disorders, the diagnosis may also incorporate transferrin saturation. Treatment of underlying diseases is recommended along with iron supplementation. While oral iron supplements are the first choice, intravenous iron may be considered when oral administration is impractical, iron absorption is impaired, or rapid iron replenishment is necessary. Recently, high-dose intravenous iron formulations became available in Japan, but their use requires caution due to potential risks of allergic reactions, hypophosphatemia/osteomalacia, iron overload, and vascular leakage. Notably, the benefits of high-dose intravenous iron for patients with heart failure and iron deficiency are recognized in the field of cardiology. This article provides an overview, incorporating recent developments in the field of iron deficiency anemia.

Ten-year anemia as initial manifestation of Castleman disease in the abdominal cavity: A case report.

Castleman disease (CD) is a relatively rare lymphoproliferative disorder. Lesions predominantly originate on the chest and neck and rarely occur on the abdomen. A 34-year-old female presented to our hospital with an unexplained 10-year history of anemia. A pathological diagnosis of plasma cell-type CD was established. One cycle of chemotherapy (thalidomide, cyclophosphamide, and prednisolone) improved her anemia significantly. Prompt etiological diagnosis and early intervention are essential to address systemic manifestations in patients with CD, and it is crucial to consider CD as a differential diagnosis when intra-abdominal masses are detected.

Impact of payment source, referral site, and place of residence on outcomes after allogeneic transplantation in Mexico.

BACKGROUND: The impact of social determinants of health in allogeneic transplant recipients in low- and middle-income countries is poorly described. This observational study analyzes the impact of place of residence, referring institution, and transplant cost coverage (out-of-pocket vs government-funded vs private insurance) on outcomes after allogeneic hematopoietic stem cell transplantation (alloHSCT) in two of Mexico's largest public and private institutions. AIM: To evaluate the impact of social determinants of health and their relationship with outcomes among allogeneic transplant recipients in Mexico. METHODS: In this retrospective cohort study, we included adolescents and adults ≥ 16 years who received a matched sibling or haploidentical transplant from 2015-2022. Participants were selected without regard to their diagnosis and were sourced from both a private clinic and a public University Hospital in Mexico. Three payment groups were compared: Out-of-pocket (OOP), private insurance, and a federal Universal healthcare program "Seguro Popular". Outcomes were compared between referred and institution-diagnosed patients, and between residents of Nuevo Leon and out-of-state. Primary outcomes included overall survival (OS), categorized by residence, referral, and payment source. Secondary outcomes encompassed early mortality, event-free-survival, graft-versus-host-relapse-free survival, and non-relapse-mortality (NRM). Statistical analyses employed appropriate tests, Kaplan-Meier method, and Cox proportional hazard regression modeling. Statistical software included SPSS and R with tidycmprsk library. RESULTS: Our primary outcome was overall survival. We included 287 patients, n = 164 who lived out of state (57.1%), and n = 129 referred from another institution (44.9%). The most frequent payment source was OOP (n = 139, 48.4%), followed by private insurance (n = 75, 26.1%) and universal coverage (n = 73, 25.4%). No differences in OS, event-free-survival, NRM, or graft-versus-host-relapse-free survival were observed for patients diagnosed locally vs in another institution, nor patients who lived in-state vs out-of-state. Patients who covered transplant costs through private insurance had the best outcomes with improved OS (median not reached) and 2-year cumulative incidence of NRM of 14% than patients who covered costs OOP (Median OS and 2-year NRM of 32%) or through a universal healthcare program active during the study period (OS and 2-year NRM of 19%) (P = 0.024 and P = 0.002, respectively). In a multivariate analysis, payment source and disease risk index were the only factors associated with overall survival. CONCLUSION: In this Latin-American multicenter study, the site of residence or referral for alloHSCT did not impact outcomes. However, access to healthcare coverage for alloHSCT was associated with improved OS and reduced NRM.

Update on iron supplementation in patients with cancer-related anemia.

INTRODUCTION: Numerous clinical trials affirm the efficacy and safety of IV iron to treat cancer-related anemia (CRA). Nonetheless, evaluation and treatment of CRA remains suboptimal. AREAS COVERED: This review summarizes CRA therapy with a focus on iron deficiency and its treatment. The literature search was conducted using the National Library of Medicine (PubMed) database from 2004 to 2024. Topics reviewed include CRA pathophysiology, laboratory diagnosis of iron deficiency, a summary of clinical trial results using IV iron to treat CRA, and safety aspects. EXPERT OPINION: Despite overwhelming positive efficacy and safety data, IV iron remains underutilized to treat CRA. This is likely due to persistent (unfounded) concerns about IV iron safety and lack of physician awareness of newer clinical trial data. This leads to poor patient quality of life and patient exposure to anemia treatments that have greater safety risks than IV iron. Solutions to this problem include increased educational efforts and considering alternative treatment models in which other providers separately manage CRA. The recent availability of new oral iron therapy products that are effective in treating anemia of inflammation has the potential to dramatically simplify the treatment of CRA.

Hematological manifestation of Pediatric Systemic Lupus Erythematosus (SLE) - A single centered cross-sectional study.

Introduction: Systemic lupus erythematosus (SLE), the commonest type of lupus, is an autoimmune multisystemic disorder that can affect any organ system of the body, especially blood vessels and connective tissues, causing widespread inflammation. Pediatric onset of SLE is a rare condition with more hematological involvement. Aim: This study was undertaken to observe various hematological abnormalities and their association with various autoantibodies present in pediatric SLE in Eastern India. Methodology: It was a single-centered, cross-sectional, observational, hospital-based study conducted in the Department of Pediatric Medicine in collaboration with the Department of Rheumatology in IPGME and R and SSKM Hospital, Kolkata. The duration of the study was 1.5 years, and a total of 30 children up to 12 years of age of either gender were enrolled. Study participants were evaluated for various parameters like demographic, hematological (anemia, neutropenia, leucopenia, lymphopenia, and thrombocytopenia), biochemical (CRP, Lactate dehydrogenase (LDH), and bilirubin), autoantibodies (anti-dsDNA, anti-Ro 52, and anti-Ribonucleoprotein [RNP]), and SLE related pathologies (Cutaneous, nephritis, serositis). Results: In the present study, most of the participants had arthritis, muscle pain (86.66%), and hematological involvement (80%). Among cytopenias, anemia was the commonest. dsDNA autoantibody was positive in most of the patients (83%), and about one-third suffered from autoimmune hemolytic anemia (AIHA). No association was observed between autoantibodies and various hematological manifestations. Conclusion: It can be concluded from the present study that anemia is the most common cytopenia in pediatric SLE, but there is no association between autoantibodies and these cytopenias. However, study on larger population may give better results.

Momelotinib - a promising advancement in the management of myelofibrosis in adults with anemia.

Myelofibrosis (MF) is a rare BCR-ABL negative myeloproliferative neoplasm characterized by clonal proliferation of stem cells, with mutations in JAK2, CALR, or MPL genes. MF presents in primary and secondary forms, with common symptoms including splenomegaly, anemia, and thrombocytopenia. Diagnostic criteria involve bone marrow examination and mutation studies. Current treatments are limited, with allogeneic stem cell transplant as the only curative option. Recent FDA approval of Momelotinib (MMB) offers new promise for MF patients with anemia. MMB, a JAK1/2 and ACVR1 inhibitor, effectively reduces spleen size, improves hemoglobin levels, and decreases transfusion dependency. The MOMENTUM trial compared MMB to danazol in JAK inhibitor-treated MF patients with anemia, showing MMB's superior symptom relief and transfusion independence rates. Additionally, the SIMPLIFY-1 and SIMPLIFY-2 trials evaluated MMB in JAK inhibitor-naïve and experienced patients, respectively, confirming MMB's non-inferiority to ruxolitinib in spleen volume reduction and highlighting its benefits in transfusion requirements. MMB's unique dual inhibition mechanism addresses anemia by suppressing hepcidin production, thus enhancing erythropoiesis. These trials collectively suggest MMB as an effective treatment for MF, improving quality of life and offering a survival advantage for patients with anemia. Despite challenges, such as trial design limitations and adverse events, MMB represents a significant advancement in MF management, providing a new therapeutic option for a previously underserved patient population.

Waldenström Macroglobulinemia - A State-of-the-Art Review: Part 1: Epidemiology, Pathogenesis, Clinicopathologic Characteristics, Differential Diagnosis, Risk Stratification, and Clinical Problems.

Waldenström macroglobulinemia (WM) is an infrequent variant of lymphoma, classified as a B-cell malignancy identified by the presence of IgM paraprotein, infiltration of clonal, small lymphoplasmacytic B cells in the bone marrow, and the MYD88 L265P mutation, which is observed in over 90% of cases. The direct invasion of the malignant cells into tissues like lymph nodes and spleen, along with the immune response related to IgM, can also lead to various health complications, such as cytopenias, hyperviscosity, peripheral neuropathy, amyloidosis, and Bing-Neel syndrome. Chemoimmunotherapy has historically been considered the preferred treatment for WM, wherein the combination of rituximab and nucleoside analogs, alkylating drugs, or proteasome inhibitors has exhibited notable efficacy in inhibiting tumor growth. Recent studies have provided evidence that Bruton Tyrosine Kinase inhibitors (BTKI), either used independently or in conjunction with other drugs, have been shown to be effective and safe in the treatment of WM. The disease is considered to be non-curable, with a median life expectancy of 10 to 12 years.

The CARMEN-France registry of adult patients with immune thrombocytopenia and autoimmune hemolytic anemia in France.

The CARMEN-France registry is a prospective, multicenter registry in France including adult patients with a new diagnosis of immune thrombocytopenia or of autoimmune immune hemolytic anemia (2402 patients included in December 31, 2023). The recording of clinical, biological and treatment data allows detailed epidemiological and pharmacoepidemiological real-world studies. This review summarizes the CARMEN-France registry protocol, gives examples of studies conducted in the registry, and indicates future directions such as inclusion of patient reported outcomes, linkage with the French national health insurance database and linkage with other registries in Europe.

Exploring the Possible Link Between Diabetic Ketoacidosis, Glucose-6-Phosphate Dehydrogenase Deficiency, and Methemoglobinemia.

One of the most widespread enzymopathies affecting human beings is glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is brought on by inherited mutations in the X-linked gene. Red blood cells (RBCs) with a G6PD deficiency are more sensitive to oxidative assault and consequently to hemolysis. There are more than 200 known G6PD mutations, of which around half are polymorphic and thus prevalent in a variety of populations. We present a case of diabetic ketoacidosis (DKA), with severe hemolytic anemia and methemoglobinemia. The patient was admitted to the intensive care unit, treated for DKA, and received a blood transfusion. In addition, the patient presented with high methemoglobin levels and features of severe hemolytic anemia from the onset, which made the diagnostic consideration of G6PD highly likely. Accordingly, the patient was treated with several doses of ascorbic acid instead of methylene blue. In a nutshell, a patient with DKA who has hemolytic anemia has to have it properly evaluated and controlled. The link between methemoglobinemia, G6PD deficiency, and DKA should be recognized by medical professionals, particularly when oxygen saturation gaps are found.

Association between magnesium, erythropoietin resistance and mortality: the Japanese Dialysis Outcomes and Practice Patterns Study (J-DOPPS).

Background: Limited data are now available to evaluate the relationship between serum magnesium level, anemia and mortality in the dialysis population. Methods: Using data from the Japanese Dialysis Outcomes and Practice Patterns Study (J-DOPPS) phases 5 and 6, we analyzed the association between serum magnesium (s-Mg) levels and the erythropoiesis-stimulating agents resistance index (ERI) as the primary outcome. To estimate the longitudinal relationship, a mixed-effect model was used with ERI at each 4-month period as the dependent variable and quintiles of s-Mg at the previous 4-month period as the independent variable. We also examined incidence of infectious events, and the all-cause and cardiovascular disease (CVD)-related deaths as secondary outcomes by Cox regression with quintiles of s-Mg at baseline. Results: Of the 4776 participants in J-DOPPS, 1650 were included in the analysis. The median of s-Mg at baseline was 2.5 mg/dL. A significant linear association of s-Mg with ERI (P for trend <.001) was revealed. Low and high s-Mg levels were not associated with the clinical outcomes of interest, except for the highest quintile of s-Mg being significantly associated with lower incidence of all-cause mortality and CVD-related deaths compared with the middle (reference) quintile. Conclusions: We observed that lower s-Mg levels subsequently induced higher ERI and that mild higher s-Mg levels were possibly associated with good rather than poor outcomes in Japanese hemodialysis patients. Adjustment of s-Mg levels may be proposed as a new strategy at a low cost and risk to reduce the risk of premature mortality.
