Prognostic impact of anemia according to frailty status in elderly patients with acute coronary syndromes.
2019
Aims Anemia is associated with poorer outcomes in patients with acute coronary syndromes (ACS), but the magnitude of this association in elderly patients remains poorly understood. No study has assessed the prognostic impact of anemia according to frailty status in this setting. Methods The LONGEVO-SCA registry included unselected ACS patients aged at least 80 years. A geriatric assessment was performed during hospitalization, including frailty assessment using the FRAIL scale. Anemia was defined by the WHO criteria. We evaluated the impact of anemia on 6-month mortality according to the presence of frailty. Results A total of 517 patients were assessed. Mean age was 84.3 years, and a total…
Hemoglobin, C-reactive protein and ferritin in patients with oral carcinoma and their clinical significance – A prospective clinical study
2017
For oral squamous cell carcinoma (OSCC), biomarkers are much in need to predict prognosis and to overcome possible resistance mechanisms to adjuvant therapies. The aim of this study was to evaluate serum level of hemoglobin, C-reactive protein (CRP) and ferritin as possible liquid biopsy to predict survival, metastasis and tumor relapse of OSCC.A prospective clinical study was conducted. Overall, serum levels of hemoglobin, CRP and ferritin in 82 OSCC patients and 63 controls were preoperatively investigated.Patients with an anemia showed a significant lower survival than patients with no anemia preoperative. Patients with T3/T4 cancer had significant lower hemoglobin values (p = 0.002). CR…
Tumor Oxygenation in Anemic Rats: Effects of Erythropoietin Treatment Versus Red Blood Cell Transfusion
1995
Anemia was induced in rats by the development of a hemorrhagic ascites. These animals also bore solid tumors (DS-sarcomas) on the hind foot dorsum. The effects of two methods for anemia correction on oxygenation in the solid tumors were compared in this study. Anemia was corrected either chronically by erythropoietin administration (1000 IU/kg) over 14 days (EPO) or acutely by transfusion with red blood cells (TR). Non-anemic and untreated anemic animals served as controls. Tumor oxygenation was determined in anesthetized animals using polarographic needle electrodes and pO2 histography. The reduction in hematocrit and hemoglobin content found in anemic animals could successfully be correct…
Haemolytic-uremic syndrome due to infection with adenovirus
2018
Abstract Rationale: Haemolytic-uremic syndrome is a rare but serious complication of bacterial and viral infections, which is characterized by the triad of: acute renal failure, microangiopathic haemolytic anemia and thrombocytopenia, sometimes severe, requiring peritoneal dialysis. In Europe, hemolytic-uremic syndrome (HUS) in paediatric pathology is primarily caused by Shiga toxin-producing Escherichia coli (STEC) O157, followed by O26. Beside these etiologies, there are other bacterial and viral infections, and also noninfectious ones that have been associated to lead to HUS as well: in the progression of neoplasia, medication-related, post-transplantation, during pregnancy or associated…
Contrast-induced Nephropathy after Percutaneous Coronary Intervention in Simple Lesions: Risk Factors and Incidence are Affected by the Definition Ut…
2011
Aim To compare the incidence, and risk factors, in-hospital and at the 18-month prognosis of contrast-induced nephropathy (CIN) according to the definition utilized: as an increase in serum creatinine (Scr) ≥0.5 mg/dL (CIN 1) or as an increase in Scr ≥25% above baseline values (CIN 2). Methods and Results We prospectively evaluated CIN according to two different definitions in 150 patients who underwent percutaneous coronary intervention (PCI) in simple lesions employing a low-medium dose of contrast media. Incidence of CIN was higher using the CIN 2 definition than CIN 1 (9.3% vs. 4%; p=0.0133). Patients with CIN 1 had a higher incidence of chronic kidney disease (CKD) (66.7% vs. 13.9%; p=…
A new machine learning approach for predicting the response to anemia treatment in a large cohort of End Stage Renal Disease patients undergoing dial…
2015
Chronic Kidney Disease (CKD) anemia is one of the main common comorbidities in patients undergoing End Stage Renal Disease (ESRD). Iron supplement and especially Erythropoiesis Stimulating Agents (ESA) have become the treatment of choice for that anemia. However, it is very complicated to find an adequate treatment for every patient in each particular situation since dosage guidelines are based on average behaviors, and thus, they do not take into account the particular response to those drugs by different patients, although that response may vary enormously from one patient to another and even for the same patient in different stages of the anemia. This work proposes an advance with respec…
Obesity and iron deficiency anemia as risk factors for asymptomatic bacteriuria.
2013
Background: Few studies examined the risk factors of asymptomatic bacteriuria, showing contradictory results. Our study aimed to examine the association between different clinical and laboratory parameters and asymptomatic bacteriuria in internal medicine patients. Materials and methods: 330 consecutive hospitalized subjects, asymptomatic for urinary tract infections (UTIs), underwent to microscopic examination of urine specimens. 100 subjects were positive for microscopic bacteriuria and were recruited into the study. At the quantitative urine culture 31 subjects of study population were positive while 69 subjects were negative for bacteriuria. Results: The analysis of clinical characteris…
Blood Transfusion in Elderly Patients with Acute Myocardial Infarction: Data from the RICO Survey.
2017
Red blood cell transfusion benefit during acute myocardial infarction remains unclear in the elderly. We aimed to assess the transfusion impact on 1-year mortality in acute myocardial infarction patients aged ≥65 years, according to their age and hemoglobin nadir.We included 3316 consecutive patients with acute myocardial infarction aged ≥65 years from the "obseRvatoire des Infarctus de Côte d'Or" (RICO) survey. They were categorized according to their hemoglobin nadir (≤8,8 to ≤10, and10 g/dL) and age (80 or ≥80 years).A total of 1906 patients (57%) were 65-79 years old, and 1410 (43%) were aged ≥80 years, of whom 103 (5%) and 145 (10%) patients received red blood cell transfusion, respect…
Effects of red blood cell transfusion on anemia-related symptoms in patients with cancer.
2009
The aim of this study was to assess the effects of red blood cell transfusion, and the subsequent increase in hemoglobin values, on anemia-related symptoms in a cohort of patients with cancer with different survival times. A red blood cell transfusion was recommended to a consecutive sample of patients with hemoglobin levels of 8 +/- 0.5 g/dL. The number of units to be ordered was decided according the hemoglobin values with a mean target of increasing the hemoglobin values by approximately 2 g/dL. Hemoglobin values, anemia-related signs and symptoms, including well-being, fatigue, and dyspnea, were recorded at admission (T0), 1 day after the last transfusion (T1), and 15 days afterward (T2…
Successful treatment of gastrointestinal bleeding with recombinant factor VIIa after kidney transplantation in patients with pancytopenia.
2006
Abstract Hemostatic disorders can often complicate transplantation procedures. Moreover, antihemmorhagic drugs may not efficiently control bleeding that occurs in such cases. We report on a patient who underwent kidney transplantation complicated by bone marrow aplasia and gastric bleeding who was succesfully treated with recombinant activated FVII (Novoseven). In May 2005, a 53-year-old man affected by chronic renal insufficiency underwent kidney transplantation. At the beginning of June, laboratory tests showed progressive reduction in the blood cell count with anemia, granulocytopenia, and thrombocytopenia related to the development of marrow insufficiency. We commenced transfusion thera…
