Screening of 143 children 6 months to 12 years of age with sickle-cell anemia showed that 39.2% were HBsAg-positive as compared with 19.3% of the 161 control children of the same age group, who had Hb genotype AA (chi 2 = 14.7383; P less than 0.001). Fifty percent of the HbSS children under the age of 1 year were HBsAg-positive as opposed to 4.3% of the control group (chi 2 = 9.1955; P less than 0.001), while 28.6% of patients were HBsAg-positive at the age of 4 years compared with only 7.4% of the controls at the same age. The incidence of anti-HBc in both groups was similar. Markers of HBV infection (HBsAg + anti-HBc) were, however, on the whole higher in the patients with sickle-cell anemia [88/118 (74.6%)] than in the controls [54/88 (61.3%; P less than 0.005)]. 相似文献

Introduction
Acquired severe aplastic anemia (SAA) is a rare and progressive disease characterized by an immune-mediated functional impairment of hematopoietic stem cells. Transplantation of these cells is a first-line treatment option if HLA-matched related donors are available. First-line immunosuppressive therapy may be offered as alternative. The aim was to compare the outcome of these patients in controlled trials.Methods
A systematic search was performed in the bibliographic databases MEDLINE, EMBASE, and The Cochrane Library. To show an overview of various outcomes by treatment group we conducted a meta-analysis on overall survival. We evaluated whether studies reported statistically significant factors for improved survival.Results
26 non-randomized controlled trials (7,955 patients enrolled from 1970 to 2001) were identified. We did not identify any RCTs. Risk of bias was high except in 4 studies. Young age and recent year of treatment were identified as factors for improved survival in the HSCT group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the IST group. In 19 studies (4,855 patients), summary statistics were sufficient to be included in meta-analysis. Considerable heterogeneity did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies.Conclusions
Young age and recent year of treatment were identified as factors for improved survival in the transplant group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the immunosuppressive group. Considerable heterogeneity of non-randomized controlled studies did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies. 相似文献4.

This study was a prospective cross-sectional cohort study of 125 patients with sickle cell anemia (SS) between the ages of 16 to 60 years. Enrolled patients were followed-up prospectively for 15 months. Demographic, clinical, hematological and routine biochemical data were obtained on all patients. Six-minute walk test and Doppler Echocardiography were performed on all patients. A tricuspid regurgitant jet velocity (TRJV) < 2.5 m/sec was considered normal, 2.5 ≤ TRJV ≤ 3.0 was considered mild-moderate and > 3.0 m/sec, severe. Patients with abnormal TRJV were significantly older and more anemic, had significantly higher lactate dehydrogenase (LDH) levels, reticulocyte count and incidence of death. The logistic multimodal model implemented for the 125 patients indicated that age was the covariate that influenced the outcome of normal or abnormal TRJV with a cutoff age of thirty-two years. The survival rate for the group of patients with creatinine (Cr) > 1.0 mg/dL was lower than the group with Cr ≤ 1 and normal TRJV. A coefficient matrix showed that the LDH values were weakly correlated with the reticulocyte count but strongly correlated with hemoglobin suggesting that the TRJV values were not correlated with the hemolytic rate but with anemia. Ten patients died during the follow-up of whom 7 had TRJV > 2.5 m/sec. Acute chest syndrome was the most common cause of death followed by sepsis. In conclusion, this study shows that patients with SS older than thirty-two years with high LDH, elevated TRJV, severe anemia and Cr > 1 have poor prognosis and may be at risk of having pulmonary hypertension and should undergo RHC. 相似文献

Background and aim. About 35% of iron deficiency anemia cases remain unexplained after a gastrointestinal evaluation. An association between Helicobacter pylori and iron malabsorption has been suggested. The aim of this study was to determine whether H. pylori‐associated chronic gastritis is linked to unexplained iron deficiency anemia in adults. Methods. From 1996 to 2001, we identified 105 patients with unexplained iron deficiency anemia after upper endoscopy, colonoscopy, small bowel radiographic examination and duodenal biopsies. Two biopsies were obtained from the gastric antrum and two from the corpus of each patient. Gastritis status was described according to the Sydney System and H. pylori infection was assessed by an immunohistochemical test on biopsy specimens. This group was compared to a control group matched for sex and age. Results. There were 76 women and 29 men (mean age 57.4 ± 21.4 years) examined in the study. A H. pylori‐associated chronic gastritis was identified in 63 cases (60%) vs. 45 cases (43%) cases in the control group (p < .01). Atrophic gastritis was significantly associated with iron deficiency anemia compared with the control group [16 (15%) vs. 6 (6%); p < .03]. In the unexplained iron deficiency anemia group, (1) patients with chronic gastritis were significantly younger (52 ± 22 vs. 64 ± 20 years; p < .005), and (2) chronic gastritis was not linked to sex [sex ratio (male/female): 0.5 vs. 0.34, p = .34]. The prevalence of H. pylori infection was similar between premenopausal and postmenopausal women [28 (27%) vs. 26 (25%); p = .7] with iron deficiency anemia. Conclusion. H. pylori infection and chronic gastritis, especially atrophic gastritis, are significantly associated with unexplained iron deficiency anemia. Relationships between H. pylori‐associated chronic gastritis and unexplained iron deficiency anemia should be considered. 相似文献

To improve the quality of diagnostics and treatment of patients with immunodeficient states, two groups of patients were examined for the presence of cytomegalovirus (CMV) infection, among them 1,348--with clinical manifestations of CMV infection (group 1) and 335 hematological patients (group 2); in addition, 36 patients with secondary immunodeficiency and 31 patients with aplastic and hemolytic anemia, or with anemia of unclear origin were examined for the presence of parvovirusinfection (B19). The results of enzyme immunoassay, polymerase chain reaction and immunofluorescence tests active CMV infection, confirmed by determination of IgM, low avidity IgG, antigen and DNAemia, was registered in group 2 more often than in group 1. Examinations on the presence of parvovirus infection revealed that in anemia patients with the low level of IgG or its absence IgM was also detected more often than in group 1. In mixed infection caused by CMV and parvovirus B19 the disease took a more severe course than in monoinfection, which was probably due to the parallel action exerted by parvovirus on erythrocyte production in hematopoiesis and by CMV on the monocytic and macrophagal row of cell. 相似文献

Background. A few cases relating H. pylori infection to iron-deficiency anemia have been described recently. We investigated the role of H. pylori infection in iron-deficiency anemia in preadolescent children and adolescents.
Patients and Methods. We conducted a double-blind, placebo-controlled therapeutic trial in 43 subjects (mean age, 15.4 years) with iron-deficiency anemia. Endoscopy was performed, and biopsy specimens were examined by urease test and histological analysis. Twenty-two of 25 H. pylori –positive patients were assigned randomly to three groups. Group A patients were given oral ferrous sulfate and a 2-week course of bismuth subcitrate, amoxicillin, and metronidazole. Group B patients were given placebo for iron and a 2-week course of triple therapy. Group C patients were given oral ferrous sulfate and a 2-week course of placebo. Iron status was reassessed 4 weeks and 8 weeks after the 2-week regimen ended.
Results. Of the 43 subjects with iron-deficiency anemia, 25 (58.1%) had H. pylori in the antrum. Group A and B subjects, who received eradication therapy, showed a significant increase in hemoglobin level as compared with group C subjects at 8 weeks after therapy ( p = .0086).
Conclusions. Treatment of H. pylori infection was associated with more rapid response to oral iron therapy as compared with the use of iron therapy alone. Such treatment also led to enhanced iron absorption even in those subjects who did not receive oral iron therapy. 相似文献

ObjectiveTo determine the prevalence of anemia in a cohort of patients with diabetes and normal serum creatinine concentration in a primary care clinic.MethodsWe undertook a retrospective cohort study, comparing adult patients who had diabetes, with or without anemia. Patients older than 18 years who had diabetes were identified by using the computerized database for the years 2006 and 2007 in a primary care clinic. Patients with hemoglobin levels < 13.7 g/dL (men < 60 years old), ≤ 13.2 g/dL (men ≥ 60 years old), or < 12.2 g/dL (women) with no known cause of anemia were identified and compared with patients who had diabetes but not anemia. All patients had normal serum creatinine levels (men ≤ 1.5 mg/dL and women ≥ 1.4 mg/dL).ResultsOf 594 eligible patients with diabetes, 192 (32%) had anemia. Older age, higher serum urea and creatinine levels, lower estimated glomerular filtration rates, and reduced serum iron levels were more common in the patients with diabetes who had anemia than in those without anemia. The prevalence of anemia was higher in patients treated with “glitazones,” insulin, and angiotensin receptor blockers in comparison with those receiving other orally administered hypoglycemic medications. In stepwise logistic regression analysis, only serum creatinine, age, and use of glitazones retained statistical significance.ConclusionIn a community clinic, the prevalence of anemia in unselected patients with diabetes and normal serum creatinine levels was 32%. Factors associated with anemia were older age, higher serum creatinine levels, and use of glitazone therapy. (Endocr Pract. 2009;15:714-719) 相似文献

Background
Anemia is a common complication among patients with chronic kidney disease (CKD), and it is associated with unfavorable clinical outcomes in patients with CKD independent of the estimated glomerular filtration rate (eGFR). We assessed the association of the urinary albumin-to-creatinine ratio (ACR) and eGFR with anemia in CKD patients.Methods
We conducted a cross-sectional study using baseline data from the KoreaN Cohort Study for Outcome in Patients With Chronic Kidney Disease (KNOW-CKD). Multiple regression analysis was performed to identify the independent association of albuminuria with anemia. Furthermore, odds ratios for anemia were calculated by cross-categorization of ACR and eGFR.Results
Among 1,456 patients, the mean age was 53.5 ± 12.4 years, and the mean eGFR and ACR were 51.9 ± 30.5 mL/min per 1.73 m2 and 853.2 ± 1,330.3 mg/g, respectively. Anemia was present in 644 patients (40.5%). Multivariate analysis showed that the odds ratio of anemia increased according to ACR levels, after adjusting for age, sex, eGFR, body mass index, pulse pressure, cause of CKD, use of erythropoiesis stimulating agents, serum calcium and ferritin (ACR < 30 mg/g as a reference group; 30–299 mg/g, adjusted odds ratio (OR) = 1.43, 95% confidence interval (CI) = 0.88–2.33; ≥300 mg/g, adjusted OR = 1.86, 95% CI = 1.12–3.10). In addition, graded associations were observed in cross-categorized groups of a higher ACR and eGFR compared to the reference group with an ACR <30 mg/g and eGFR ≥60 mL/min per 1.73 m2.Conclusion
The present study demonstrated that albuminuria was a significant risk factor for anemia in CKD patients independent of the eGFR. 相似文献13.

Summary In the last ten years the ABO blood groups of our infants have been constantly ascertained and their distribution among some of the more prevalent diseases have been investigated. Other infants and healthy new-borns were used for comparison. The following results have been found:The blood group O is slightly more frequent in sick babies than in healthy new-borns. Among patients, who were under the age of 2 months at the time of admission, there were more with blood group O than among the older children. The blood group A tends to increase among the infants with anemia and with acute respiratory diseases, the blood group O tends to increase among those with staphylococcal infections and rachitis. With the latter the blood group B seems also to be found a little more frequently.Statistics show the increase of the blood group A in anemia in the 3. and 4. months of life and in acute respiratory diseases between the 3. and 12. month of life. The increase of the blood group O in staphylococcal infections is sure only among the youngest patients during their 1. month of life, it is obvious among the older patients, and there mainly among those of masculine sex. The increase of the blood groups O and B among infants with rachitis at the age of 3 to 12 months is almost certain. Premature babies show a sure decrease of the blood group O among both sexes, an increase of the blood group A among feminine, and of the blood group B among masculine patients. 相似文献

Background
Anemia during childhood impairs physical growth, cognitive development and school performance. Identifying the causes of anemia in specific contexts can help efforts to prevent negative consequences of anemia among children. The objective of this study was to assess prevalence and identify correlates of anemia among school children in Eastern Ethiopia.Methods
A cross sectional study was conducted from January 2012 to February 2012 in Kersa, Eastern Ethiopia. The study included randomly selected primary school students. Hemoglobin concentration was measured using a Hemocue haemoglobinometer. A child was identified as anemic if the hemoglobin concentration was <11.5 g/dl for children (5–11 yrs) and < 12 g/dl for child older than 12 years age. Poisson regression model with robust variance was used to calculate prevalence ratios.Result
The overall prevalence of anemia was 27.1% (95% CI: 24.98, 29.14): 13.8% had mild, 10.8% moderate, and 2.3% severe anemia. Children with in the age group of 5-9 years (APR, 1.083; 95% CI, 1.044- 1.124) were at higher risk for anemia. Paternal education (Illiterate, 1.109; 1.044 - 1.178) was positively associated with anemia. Children who had irregular legume consumption (APR, 1.069; 95% CI, 1.022 -1.118) were at higher risk for anemia.Conclusion
About a quarter of school children suffer from anemia and their educational potential is likely to be affected especially for those with moderate and severe anemia. Child age, irregular legume consumption, and low paternal schooling were associated with anemia. Intervention programmes aimed to reduce anemia among school children are crucial to ensure proper growth and development of children. 相似文献15.

The mechanism responsible for the isolated intrinsic factor deficiency in congenital pernicious anemia is unknown. A new second-antibody radioimmunoassay capable of recognizing intrinsic factor independent of the molecule's ability to bind added cobalamin was used to study six patients from three kindreds with this disorder. One of the patients was first diagnosed at age 23 because of unusual circumstances in her case; yet the other patients also demonstrated great age variability at presentation of this presumably congenital disorder, even within the same kindred. The radioimmunoassay failed to detect immunoreactive intrinsic factor in any of the six patients, suggesting that elaboration of an abnormal molecule was not the pathogenetic mechanism. An unexpected incidental finding, contrasting with this observation in congenital pernicious anemia, was immunologic evidence that a previously described patient with familial R binder deficiency clearly elaborated an abnormal R binder molecule. 相似文献

Introduction
Anemia and diabetes are risk factors for short-term mortality following an acute myocardial infarction(AMI). Anemia is more prevalent in patients with diabetes. We performed a retrospective study to assess the impact of the combination of diabetes and anemia on post-myocardial infarction outcomes.Methods
Data relating to all consecutive patients hospitalized with AMI was obtained from a population-based disease-specific registry. Patients were divided into 4 groups: diabetes and anemia (group A, n = 716), diabetes and no anemia (group B, n = 1894), no diabetes and anemia (group C, n = 869), and no diabetes and no anemia (group D, n = 3987). Mortality at 30 days and 31 days to 36 months were the main outcome measures.Results
30-day mortality was 32.3% in group A, 16.1% in group B, 21.5% in group C, 6.6% in group D (all p < 0.001). 31-day to 36-month mortality was 47.6% in group A, 20.8% in group B, 34.3% in group C, and 10.4% in group D (all p < 0.001). Diabetes and anemia remained independent risk factors for mortality with odds ratios of 1.61 (1.41–1.85, p < 0.001) and 1.59 (1.38–1.85, p < 0.001) respectively at 36 months. Cardiovascular death from 31-days to 36-months was 43.7% of deaths in group A, 54.1% in group B, 47.0% in group C, 50.8% group D (A vs B, p < 0.05).Interpretation
Patients with both diabetes and anemia have a significantly higher mortality than those with either diabetes or anemia alone. Cardiovascular death remained the most likely cause of mortality in all groups. 相似文献17.

The putative prognostic significance of perioperative blood transfusions on gastric cancers is controversial and the published results are contradictory. The aim of this study was to evaluate the prognostic influence of transfusion on Chinese gastric cancer surgery. Six hundreds and seventy-six patients who underwent curative gastrectomy for gastric cancer from 2000 to 2004 were retrospectively reviewed. Uni- and multivariate analyses of the incidence and amount of transfusion, and a comparison of the clinicopathological features were performed. Subgroup analyses of prognosis according to stage, tumor size, and pretreatment anemia were carried out. Blood transfusion was significantly associated with older age (>60 year), larger tumor (>6 cm), upper and middle location, surgical margin status, and pretreatment anemia. In addition, tumors in the transfused group were more advanced in depth of invasion, nodal stage, and TNM stage. No significant relationship was found between the amount of transfused blood and prognosis. Subgroup analyses of prognosis according to stage showed significant differences in stages II and III, between the transfused and nontransfused groups. Significant difference between the transfused and nontransfused groups could be observed in two subgroups of tumor size. Patients with or without anemia in the nontransfused group both had a longer survival time than those in the transfused group. On multivariate analysis, transfusion was shown to be an independent risk factor for poor prognosis. This study suggests that perioperative blood transfusion is associated with a significantly worse prognosis following gastric cancer surgery. The parameters such as advanced stage, tumor size, and anemia do not affect its prognostic value. 相似文献

This study aims to measure iron nutrition parameters and to determine the presence of anemia in obese type 2 diabetic patients and to analyze the mRNA relative abundance of genes related to inflammation, immune system, iron metabolism, and mitochondrial activity. Obese type 2 diabetic (OBDM, n?=?30) and healthy subjects (Cn, n?=?30) were studied. Biochemical, anthropometric, and iron nutrition parameters were determined. Peripheral mononuclear cells from type 2 diabetic and control group were challenged with high concentrations of iron (Fe) and glucose and total mRNA was isolated. The frequency of anemia among diabetic patients was 4/30. OBDM patients with or without anemia had higher levels of ferritin and high-sensitivity C-reactive protein than the Cn group. mRNA relative abundance of nuclear factor kappa-light-chain-enhancer of activated B cells was elevated in OBDM with anemia, and mRNA expression of interleukin-6 and toll-like receptor (TLR) 2 was increased in OBDM group in basal high Fe and high glucose concentrations. The expression of tumor necrosis factor alpha and TLR-4 was increased in OBDM with anemia in all experimental conditions. Hepcidin mRNA expression was increased in OBDM with anemia even in basal Fe concentration, and mitofusin 2 was decreased in all experimental conditions. This study shows that obese type 2 diabetic patients have iron distribution disorders associated to their proinflammatory state, and anemic subjects have a marked elevation of hepcidin mRNA expression. 相似文献

目的:探讨脑梗死患者颈动脉粥样硬化的危险因素。方法:选取148例脑梗死患者作为实验组和同期住院的80例非脑梗死疾病患者为对照组,检测并比较各组年龄、吸烟、血压、饮酒、糖尿病、血脂、同型半胱氨酸和磷脂酶A2等指标,然后进行卡方检验、相关性和Logistic回归分析。结果:实验组颈动脉粥样硬化检出率为82.43%,对照组为12.5%,其差异具有统计学意义(P0.05)。高龄、吸烟、高血压、高血脂、高同型半胱氨酸血症、高磷脂酶A2(LP-PLA2)血症是经动脉粥样硬化的危险因素,且血浆同型半胱氨酸水平、LP-PLA2水平、血压与颈动脉斑块稳定性有关(P0.05)。结论:颈动脉粥样硬化是脑梗死的病理基础,与高龄、吸烟、高血压、高血脂、高同型半胱氨酸血症、高磷脂酶A2(LP-PLA2)血症有关,对高同型半胱氨酸血症、LP-PLA2和高血压患者要关注其斑块的稳定性。 相似文献

目的:本研究通过回顾性分析晚期胃肠癌患者化疗后血红蛋白(Hb)水平与其临床疗效的关系,为临床治疗提供依据。方法:选择2009年1月~2014年12月我院收治的晚期胃肠癌患者共85例,采用回顾性调查方法,对患者进行1~5年的随访,分别对患者化疗前后贫血发生情况、Hb水平与临床疗效的关系、Hb水平与患者平均生存时间的关系进行分析。结果:化疗后患者发生贫血的比例(78.82%)明显高于化疗前(48.24%),差异有统计学意义(P0.05);PR组和SD组患者化疗前后Hb值的差异无统计学意义(P0.05);化疗前PD组患者Hb值显著高于化疗后,差异有统计学意义(P0.05);Hb水平越高,患者的平均生存时间越长,Hb的水平和患者的生存时间呈正相关。结论:晚期胃肠癌患者化疗后贫血发生率增加,化疗后Hb水平的变化与患者的预后和生存时间均存在相关关系,对患者进行常规治疗的同时采取相应措施纠正患者贫血症状,有利于改善晚期胃肠癌患者的预后,延长患者的生存时间。 相似文献
