Renal iron recycling preserves the filtered iron from urinary excretion. However, it remains debated whether ferroportin (FPN), the solely known iron exporter, is functionally involved in renal iron recycling, and whether renal iron recycling is required for systemic iron homeostasis. We deleted FPN in the whole nephrons using a Nestin-Cre and in the distal nephrons and collecting ducts using a Ksp-Cre, and investigated its impacts on renal iron recycling and systemic iron homeostasis. FPN deletion by Nestin-Cre but not by Ksp-Cre caused excess iron retention and increased ferritin heavy chain (FTH1) specifically in the proximal tubules, and resulted in the reduction of serum and hepatic iron...

Objective: Endurance runners may experience "sports anemia" resulting from intravascular hemolysis. In addition, aging has negative impact on hematopoiesis and rheological properties of blood, and erythrocyte membranes in older people are more vulnerable to oxidative damage, which together can lead to anemia. Whole-body cryostimulation (WBCST) is increasingly used in the elderly as a method of biological regeneration of athletes or therapy and preventive treatment. That is why the aim of the study was to determine whether repeated WBCST had an effect on the erythrocyte system in master marathon runners, compared to non-training men...

The results of RESONATE-2 (PCYC-1115/1116) supported the approval of ibrutinib for first-line treatment of chronic lymphocytic leukemia. An extended analysis of RESONATE-2 was conducted to determine long-term efficacy and safety of ibrutinib in older patients with chronic lymphocytic leukemia. A total of 269 patients aged ≥65 years with previously untreated chronic lymphocytic leukemia were randomized 1:1 to ibrutinib (n=136) or chlorambucil (n=133) on days 1 and 15 of a 28-day cycle for 12 cycles. Median ibrutinib treatment duration was 28...

BACKGROUND: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. AIM: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF...

An 81-year-old Japanese man presented with constitutional symptoms and anemia and was diagnosed with giant cell arteritis (GCA) and myelodysplastic syndrome (MDS) simultaneously. His symptoms and anemia improved promptly with steroids; however, the MDS rapidly progressed to overt leukemia. While MDS patients are at an increased risk of autoimmune diseases, an association with GCA has rarely been reported. This case illustrates the importance of considering GCA as a cause of anemia in elderly patients if MDS is already diagnosed, even in countries where the prevalence of GCA is very low...

Anemia is an independent risk factor for functional decline and mortality among older adults. Since mild anemia in older people is often under-diagnosed and ignored, its prevalence needs precise determination and recognition of predisposing factors. None of the previous studies based on the data obtained from the representative elderly population identified the influence of socio-economic factors on the prevalence of anemia. PolSenior was a cross-sectional population-based study performed on the nationally representative sample of Polish seniors...

BACKGROUND: Hemolytic features in patients with pernicious anemia have not been emphasized. METHODS: Seven Japanese patients at 60 - 88 years of age with vitamin B12 deficiency-related hemolytic anemia were assessed. RESULTS: Serum vitamin B12 levels in these cases were 46 - 89 pg/mL (normal reference range: 233 - 914 pg/mL). Clinically, the patients presented with thrombotic microangiopathy (TMA)-like hemolytic features (including macrocytic anemia, schistocytes on blood smears, high serum lactate dehydrogenase, hyperbilirubinemia, and low serum haptoglobin)...

PURPOSE: Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is effective as first-line chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC) harboring sensitive EGFR mutations. However, whether the efficacy of second-line cytotoxic drug chemotherapy after first-line EGFR-TKI treatment is similar to that of first-line cytotoxic drug chemotherapy in elderly patients aged ≥ 75 years harboring sensitive EGFR mutations is unclear. Therefore, we aimed to investigate the efficacy and safety of cytotoxic drug chemotherapy after first-line EGFR-TKI treatment in elderly patients with NSCLC harboring sensitive EGFR mutations...

Clonal hematopoiesis by hematopoietic stem progenitor cells (HSPCs) that lack an HLA class I allele (HLA- HSPCs) is common in patients with acquired aplastic anemia (AA); however, it remains unknown whether the cytotoxic T lymphocyte (CTL) attack that allows for survival of HLA- HSPCs is directed at nonmutated HSPCs or HSPCs with somatic mutations or how escaped HLA- HSPC clones support sustained hematopoiesis. We investigated the presence of somatic mutations in HLA- granulocytes obtained from 15 AA patients in long-term remission (median, 13 years; range, 2-30 years)...

RATIONALE: The current therapy for elderly patients with high-risk myelodysplastic syndromes (MDSs) remains unsatisfactory. Decitabine, which has been approved to treat MDS, cannot eliminate malignant clones of MDS. PATIENT CONCERNS: A 68-year-old woman presented with multiple divergent bleeding points in the subcutaneous tissue of the limb. Two years earlier, she had been diagnosed with invasive ductal carcinoma of the left breast and had undergone left modified radical mastectomy and local radiation therapy...
