Objectives: The objective of the present study was to assess the hemoglobin (Hb) stability of a Japanese cohort of hemodialysis (HD) patients who were simultaneously switched from darbepoetin alfa (DA) to epoetin beta pegol (CERA). Methods: This was an observational, prospective study of HD patients 20 years of age or more who were switched from intravenous (IV) DA to IV CERA and continued on HD for at least 3 months. The dose was adjusted to maintain the Hb level to within 1.0 g/dl of the baseline value. Results: A total of 68 HD patients (75.0% male, median age 63.0 years) were enrolled. The patients’ mean Hb levels were 10.8 ± (0.6) g/dl at Month 0, 10.9 ± 0.7 at Month 1, 10.8 ± 0.7 at Month 2, and 10.9 ± 0.8 at Month 3, and the differences from the level at Month 0 were not significant. After the switch, the ESA dose decreased significantly (P P < 0.0001). Conclusion: Switching from DA to CERA was associated with approximate 89% reduction of the required dose in Japanese HD patients being treated with an ESA and showed a favorable impact on the treatment of renal anemia, including the need for less frequent injections and a reduction of the ESA dose.展开更多

There is no significant difference regarding NGAL between the study groups. Significant negative correlation between CHr with ferritin, urea, creatinine, and positively correlated with iron and RBCS. CHr showed a sensitivity of 90% and specificity of 86.67% to detect iron-deficiency anemia with a cut-off value of 27 pg. <strong>Conclusion:</strong> CHr is superior to ferritin and TSAT % for the early diagnosis of iron deficiency anemia in hemodialysis children;our results do not support NGAL as a marker of anemia in hemodialysis patients.展开更多

The aim of this study was to determine the effects of anemia on quality of life and self-care agency in adult patients who receive chronic hemodialysis treatment. Methods: In this cross-sectional study, the Quality of Life Scale, the Self Care Agency Scale, and a data form were administered to 136 hemodialysis patients who were receiving treatment three hospital-based dialysis units in Istanbul. Results: The health perception of cases whose hemoglobin level was 12 mg/dl and above was significantly better than those whose hemoglobin level was lower than 12 mg/dl. Hemoglobin levels were significantly and positively correlated to physical role function, general health, and health from the previous year (p < 0.05). As the hemoglobin levels of the cases increased, quality of life pertaining to the mentioned domains increased. Conclusion: It was concluded that the quality of life in chronic dialysis patients was affected by anemia.展开更多

We hypothesize that chronic hemodialysis patients with co-existing Hepatitis C infection will have higher hemoglobin levels than chronic hemodialysis patients without hepatitis C infection. Secondly, we hypothesize that the higher hemoglobin levels will be associated with higher erythropoietin levels. Therefore we conducted a cross-sectional study of chronic hemodialysis patients with and without hepatitis C infection and evaluated associations with hemoglobin and erythropoietin levels. Our primary outcome was level of hemoglobin. Secondary outcome included association of hemoglobin and erythropoietin levels. 57 chronic hemodialysis patients (33 male, 24 female, mean age 46.05 ± 12.7 years) were included. The mean time spent on hemodialysis was 7.16 ± 6.2 years. None of the patients received any recombinant EPO therapy. Biochemical analyses include ALT, AST, Albumin, C-Reactive Protein, cholesterol levels and complete blood counts. Iron status of patients (transferrin saturation and serum ferritin levels) and parathyroid hormone were measured. Endogenous EPO serum levels were measured by a standardized enzyme-linked immunoassay. 23 of the hemodialysed patients (38.5%) were HCV (+). There was no difference in age, sex, distribution of primary renal diseases, iron status, albumin, C-Reactive-Protein and parathyroid hormone levels between HCV (+) and (-) patients. Mean duration time on dialysis was higher in HCV (+) than HCV (-) patients. Hemoglobin levels were similar between study groups. However serum endogenous erythropoietin levels were significantly higher in HCV (+) patients than HCV (-) patients (19.6 ± 10 mUI/ml vs 7.8 ± 7.7 mUI/ml, p = 0.03). No correlation has been found between the severity of anemia and HCV infection. However, HCV (+) hemodialysed patients had higher serum endogenous erythropoietin levels as compared to HCV (-) patients. Further studies are needed to clarify why high endogenous erythropoietin level does not improve anemia in HCV infected hemodialysis patients.展开更多

The serum P level before the start of ferric citrate hydrate treatment was ≤5.5 mg/dL in 18.8% of the patients. After 18 months of ferric citrate hydrate treatment, the proportion of patients with serum P levels ≤ 5.5 mg/dL increased to 47.7%. The mean ± standard error of the mean (SEM) of the serum P level was 7.05 ± 0.14 mg/dL at the baseline, and decreased to 5.83 ± 0.17 mg/dL after 18 months of treatment with ferric citrate hydrate. The mean ± SEM of the serum hemoglobin (Hb), ferritin, and transferrin saturation (TSAT) levels were 11.96 ± 0.76 g/dL, 71.13 ± 6.09 ng/mL, and 25.19% ± 1.21%, respectively, at the baseline, and 11.45 ± 0.13 g/dL, 124.94 ± 8.62 ng/mL, and 26.18% ± 0.99%, respectively, after 18 months of ferric citrate hydrate treatment. <strong>Conclusions:</strong> These results suggest that the serum P and anemia biomarker levels observed in this study were similar to those reported in clinical trials.展开更多

Methods: 132 patients receiving maintenance hemodialysis in our hospital from July 2017 to July 2019 were selected and divided into control group and observation group according to the random number table method, with 66 cases each. The observation group was treated with high-flux hemodialysis, while the control group was treated with low-flux hemodialysis for 6 months. Compare two groups before and after treatment serum beta 2 microglobulin (beta 2 - MG), serum creatinine (Scr), blood urea nitrogen (BUN) level, anemia related index [red blood cells deposited (HCT), hemoglobin (Hb), reticulocyte percentage (Ret%)], iron metabolism index [serum ferritin (SF), transferrin saturation (TSAT)、Hepcidin(Hepc)], soluble transferrin receptor (sTfR) levels and adverse reactions. Results: the levels of 2-MG, Scr and BUN in the two groups before treatment were compared (P>0.05). After treatment, Scr and BUN levels in the two groups were significantly decreased (P<0.05), but were compared between the two groups (P>0.05). The level of 2-MG in the observation group was lower than that in the control group (P<0.05). Before treatment, sTfR, Hb, HCT level and Ret% of the two groups were compared(P>0.05). After treatment, Hb and HCT levels in the observation group were higher than those in the control group, while Ret% were lower than those in the control group, (P<0.05). Before treatment, the levels of ST、TAST、sTfR and Hepc in the two groups were compared (P>0.05). After treatment, the level of ST and TAST in the observation group was higher than that in the control group, The levels of sTfR and Hepc were lower than the control group (P<0.05). The overall incidence of adverse reactions in the observation group (8.93%) was lower than that in the control group (10.14%), with no significant difference (P>0.05). Conclusion: The high-throughput hemodialysis department significantly improved renal anemia in hemodialysis patients, reduced serum sTfR level, and had fewer adverse reactions and higher safety.展开更多

According to international standards, perioperative period is not an appropriate setting to screen and investigate the cause of asymptomatic anemia, but in third world countries where iron deficiency is rampant, it is generally required as per local hospitals policy to test hemoglobin levels prior to any surgery in order to prevent morbidity. The purpose of our study is to look at the prevalence of anemia in patient undergoing minor elective ambulatory surgeries. Method: This was a cross sectional observational study conducted at tertiary care unit, Karachi, Pakistan. A total of 385 ASA-I (American Society of Anesthesiologist) and II patient’s age ranged 18 - 60 years, scheduled for day care surgical procedures were enrolled in the study. Results: Anemia was detected in 74 (19.2%) patients and its prevalence was found to be higher in females and in patients above 50 years of age. However, the presence of anemia did not have any influence on the perioperative outcomes or management. Conclusion: The routine preoperative hemoglobin testing does not have any effect on the perioperative outcomes in asymptomatic patients who are planned for elective day care surgeries.展开更多

However, limited data are available about its prevalence in sub-Saha-ran region. The aim of this study was to assessed sleep quality and its predictors among hemodialysis patients. Methods: We conducted a cross sectional study of 2 weeks in the Douala General Hospital hemodialysis center of Cameroon involving 46 chronic hemodialyzed patients for at least six months with arteriovenous fistula. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and laboratory data were collected in patients’’ fields. Result: Thirty-five (76.1%) subjects reported poor sleep quality. The most frequent abnormal sleep components were subjective sleep quality, sleep disturbances and sleep latency (87%, 85% and 76% respectively). In univariate linear regression, hemoglobin level, sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance were associated with poor sleep quality. In multivariate linear regression only hemoglobin level (p = 0.004) and sleep latency (p = 0.002) were associated with poor sleep quality. Conclusion: Poor sleep quality is frequent in our hemodialysis patients and hemoglobin seems to be a good predictor of sleep quality in these patients.展开更多

We performed a retrospective, observational cohort study to investigate the relationships between serum ferritin levels and mortality in MHD patients. Methods: MHD outpatients (n = 150) were followed up for a median period of 49 months. Their ESA and low-dose iron supplement dosages were adjusted to maintain their hemoglobin (Hb) concentrations in the 10 - 11 g/dl range in accordance with Japanese guidelines. The Kaplan-Meier method, log-rank tests, and Cox proportional hazards models were used to perform the statistical analyses. The patients were divided into 3 groups according to their serum ferritin levels: a serum ferritin 100 ng/ml group. Results: During the median follow-up period of 49 months, there were 55 deaths. The multivariate analysis showed no significant associations between the ferritin level groups and all-cause mortality or cardiovascular (CV) events, and the Kaplan-Meier analysis showed no significant differences among the 3 ferritin level groups in all-cause mortality and CV event rates. However, the multivariate analysis revealed that age, CRP level and a history of previous CV disease were independently associated with all-cause mortality, while diabetes, previous CV disease, and iron administration were independently associated with CV events. Conclusion: The results of this study revealed no significant associations of MHD patients between the ferritin ranges and all-cause mortality or CV events. Thus, the adverse clinical outcomes in these patients were independently associated with other markers and not with their serum ferritin levels.展开更多

It is commonly considered a risk factor for poor pregnancy outcomes and can result in complications that threaten the life of both mother and fetus, such as preterm birth, and low birth weight. There is clear evidence to support prompt treatment in all patients with iron deficiency anemia because it is known that treatment improves quality of life and physical condition as well as alleviates fatigue and cognitive deficits. Objective: The aim of the study was to evaluate the value of addition of vitamin B6 to iron in treatment of iron deficiency anemia in pregnant women during the second trimester. Patients and Methods: The study was done by giving anemia pregnant women iron therapy and vitamin B6 which represent group A and iron therapy alone which represents group B. For each pregnant woman, age, parity and gestational history were taken before treatment. All pregnant women took their allocated treatment regularly for three weeks after diagnosis of iron deficiency anemia with complete blood picture and followed up after three weeks. Results: Results of the study revealed that there was no statistically significant difference between the two groups of therapy according to the hemoglobin level before treatment (p-value = 0.734), statistically significant higher mean value in after treatment than before treatment (p-value = 0.048), there was a significant difference in the rate of change of hemoglobin (p-value = 0.011) and body mass index (p-value 0.001). Conclusion: Iron and vitamin B6 seems to increase hemoglobin level more than iron only. Thus, in pregnant women with iron deficiency anemia iron plus vitamin B6 may be considered as a more effective alternative treatment than iron only.展开更多

文摘Background: New erythropoiesis-stimulating agents (ESAs) with a longer half-life have been developed for the treatment of anemia as a complication of patients with end-stage renal disease. Objectives: The objective of the present study was to assess the hemoglobin (Hb) stability of a Japanese cohort of hemodialysis (HD) patients who were simultaneously switched from darbepoetin alfa (DA) to epoetin beta pegol (CERA). Methods: This was an observational, prospective study of HD patients 20 years of age or more who were switched from intravenous (IV) DA to IV CERA and continued on HD for at least 3 months. The dose was adjusted to maintain the Hb level to within 1.0 g/dl of the baseline value. Results: A total of 68 HD patients (75.0% male, median age 63.0 years) were enrolled. The patients’ mean Hb levels were 10.8 ± (0.6) g/dl at Month 0, 10.9 ± 0.7 at Month 1, 10.8 ± 0.7 at Month 2, and 10.9 ± 0.8 at Month 3, and the differences from the level at Month 0 were not significant. After the switch, the ESA dose decreased significantly (P P < 0.0001). Conclusion: Switching from DA to CERA was associated with approximate 89% reduction of the required dose in Japanese HD patients being treated with an ESA and showed a favorable impact on the treatment of renal anemia, including the need for less frequent injections and a reduction of the ESA dose.

文摘Study for influence of chronic Hepatitis C (HCV) on endogenous erythropoietin production and on anemia in dialysis patients remains inconclusive. We hypothesize that chronic hemodialysis patients with co-existing Hepatitis C infection will have higher hemoglobin levels than chronic hemodialysis patients without hepatitis C infection. Secondly, we hypothesize that the higher hemoglobin levels will be associated with higher erythropoietin levels. Therefore we conducted a cross-sectional study of chronic hemodialysis patients with and without hepatitis C infection and evaluated associations with hemoglobin and erythropoietin levels. Our primary outcome was level of hemoglobin. Secondary outcome included association of hemoglobin and erythropoietin levels. 57 chronic hemodialysis patients (33 male, 24 female, mean age 46.05 ± 12.7 years) were included.

Endogenous EPO serum levels were measured by a standardized enzyme-linked immunoassay. 23 of the hemodialysed patients (38.5%) were HCV (+). There was no difference in age, sex, distribution of primary renal diseases, iron status, albumin, C-Reactive-Protein and parathyroid hormone levels between HCV (+) and (-) patients.

However serum endogenous erythropoietin levels were significantly higher in HCV (+) patients than HCV (-) patients (19.6 ± 10 mUI/ml vs 7.8 ± 7.7 mUI/ml, p = 0.03). No correlation has been found between the severity of anemia and HCV infection. However, HCV (+) hemodialysed patients had higher serum endogenous erythropoietin levels as compared to HCV (-) patients. Further studies are needed to clarify why high endogenous erythropoietin level does not improve anemia in HCV infected hemodialysis patients.

Bone turnover marker levels, anemia status and iron biomarker levels over a period of 18 months after the start of the ferric citrate hydrate treatment were extracted from the medical records of the patients.<strong> Results:</strong> At enrollment, 14 (10.6%) patients were P-binder-na<span style="white-space:nowrap;">ï</span>ve, and 118 (89.4%) patients were receiving other P-binders. The serum P level before the start of ferric citrate hydrate treatment was ≤5.5 mg/dL in 18.8% of the patients. After 18 months of ferric citrate hydrate treatment, the proportion of patients with serum P levels ≤ 5.5 mg/dL increased to 47.7%. The mean ± standard error of the mean (SEM) of the serum P level was 7.05 ± 0.14 mg/dL at the baseline, and decreased to 5.83 ± 0.17 mg/dL after 18 months of treatment with ferric citrate hydrate. The mean ± SEM of the serum hemoglobin (Hb), ferritin, and transferrin saturation (TSAT) levels were 11.96 ± 0.76 g/dL, 71.13 ± 6.09 ng/mL, and 25.19% ± 1.21%, respectively, at the baseline, and 11.45 ± 0.13 g/dL, 124.94 ± 8.62 ng/mL, and 26.18% ± 0.99%, respectively, after 18 months of ferric citrate hydrate treatment. <strong>Conclusions:</strong> These results suggest that the serum P and anemia biomarker levels observed in this study were similar to those reported in clinical trials.

文摘Objective: To investigate the effect of high throughput hemodialysis on soluble transferrin receptor in hemodialysis patients and the improvement of renal anemia. Methods: 132 patients receiving maintenance hemodialysis in our hospital from July 2017 to July 2019 were selected and divided into control group and observation group according to the random number table method, with 66 cases each. The observation group was treated with high-flux hemodialysis, while the control group was treated with low-flux hemodialysis for 6 months. Compare two groups before and after treatment serum beta 2 microglobulin (beta 2 - MG), serum creatinine (Scr), blood urea nitrogen (BUN) level, anemia related index [red blood cells deposited (HCT), hemoglobin (Hb), reticulocyte percentage (Ret%)], iron metabolism index [serum ferritin (SF), transferrin saturation (TSAT)、Hepcidin(Hepc)], soluble transferrin receptor (sTfR) levels and adverse reactions. Results: the levels of 2-MG, Scr and BUN in the two groups before treatment were compared (P>0.05). After treatment, Scr and BUN levels in the two groups were significantly decreased (P<0.05), but were compared between the two groups (P>0.05). The level of 2-MG in the observation group was lower than that in the control group (P<0.05). Before treatment, sTfR, Hb, HCT level and Ret% of the two groups were compared(P>0.05). After treatment, Hb and HCT levels in the observation group were higher than those in the control group, while Ret% were lower than those in the control group, (P<0.05). Before treatment, the levels of ST、TAST、sTfR and Hepc in the two groups were compared (P>0.05). After treatment, the level of ST and TAST in the observation group was higher than that in the control group, The levels of sTfR and Hepc were lower than the control group (P<0.05). The overall incidence of adverse reactions in the observation group (8.93%) was lower than that in the control group (10.14%), with no significant difference (P>0.05). Conclusion: The high-throughput hemodialysis department significantly improved renal anemia in hemodialysis patients, reduced serum sTfR level, and had fewer adverse reactions and higher safety.
文摘Background: Patients coming for ambulatory surgeries are mostly healthy adults and asymptomatic anemia in these patients is rare. According to international standards, perioperative period is not an appropriate setting to screen and investigate the cause of asymptomatic anemia, but in third world countries where iron deficiency is rampant, it is generally required as per local hospitals policy to test hemoglobin levels prior to any surgery in order to prevent morbidity. The purpose of our study is to look at the prevalence of anemia in patient undergoing minor elective ambulatory surgeries. Method: This was a cross sectional observational study conducted at tertiary care unit, Karachi, Pakistan. A total of 385 ASA-I (American Society of Anesthesiologist) and II patient’s age ranged 18 - 60 years, scheduled for day care surgical procedures were enrolled in the study. Results: Anemia was detected in 74 (19.2%) patients and its prevalence was found to be higher in females and in patients above 50 years of age. However, the presence of anemia did not have any influence on the perioperative outcomes or management. Conclusion: The routine preoperative hemoglobin testing does not have any effect on the perioperative outcomes in asymptomatic patients who are planned for elective day care surgeries.
文摘Background: Poor sleep quality is reported to be common in hemodialysis patients. However, limited data are available about its prevalence in sub-Saha-ran region. The aim of this study was to assessed sleep quality and its predictors among hemodialysis patients. Methods: We conducted a cross sectional study of 2 weeks in the Douala General Hospital hemodialysis center of Cameroon involving 46 chronic hemodialyzed patients for at least six months with arteriovenous fistula. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and laboratory data were collected in patients’’ fields. Result: Thirty-five (76.1%) subjects reported poor sleep quality. The most frequent abnormal sleep components were subjective sleep quality, sleep disturbances and sleep latency (87%, 85% and 76% respectively). In univariate linear regression, hemoglobin level, sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance were associated with poor sleep quality. In multivariate linear regression only hemoglobin level (p = 0.004) and sleep latency (p = 0.002) were associated with poor sleep quality. Conclusion: Poor sleep quality is frequent in our hemodialysis patients and hemoglobin seems to be a good predictor of sleep quality in these patients.
文摘Background: The relationship between the iron indices and mortality in maintenance hemodialysis (MHD) patients has remained unclear. We performed a retrospective, observational cohort study to investigate the relationships between serum ferritin levels and mortality in MHD patients. Methods: MHD outpatients (n = 150) were followed up for a median period of 49 months. Their ESA and low-dose iron supplement dosages were adjusted to maintain their hemoglobin (Hb) concentrations in the 10 - 11 g/dl range in accordance with Japanese guidelines. The Kaplan-Meier method, log-rank tests, and Cox proportional hazards models were used to perform the statistical analyses. The patients were divided into 3 groups according to their serum ferritin levels: a serum ferritin 100 ng/ml group. Results: During the median follow-up period of 49 months, there were 55 deaths. The multivariate analysis showed no significant associations between the ferritin level groups and all-cause mortality or cardiovascular (CV) events, and the Kaplan-Meier analysis showed no significant differences among the 3 ferritin level groups in all-cause mortality and CV event rates. However, the multivariate analysis revealed that age, CRP level and a history of previous CV disease were independently associated with all-cause mortality, while diabetes, previous CV disease, and iron administration were independently associated with CV events. Conclusion: The results of this study revealed no significant associations of MHD patients between the ferritin ranges and all-cause mortality or CV events. Thus, the adverse clinical outcomes in these patients were independently associated with other markers and not with their serum ferritin levels.
文摘BACKGROUND Anemia in infants and young children can have long-term effects on cognitive and physical development.In Ma'anshan City,China,there has been growing concern about the prevalence of anemia among children aged 6 to 36 mo.Understanding the factors influencing this condition is crucial for targeted interventions and improving overall child health in the region.AIM To analyze the anemia status and influencing factors of infants and young children aged 6 to 36 mo in Ma'anshan City,China.Providing scientific evidence for reducing the incidence of anemia and improving the health level of children in this age group.METHODS The study encompassed 37698 infants and young children,aged from 6 to 36 mo,who underwent health examinations at the Ma'anshan Maternal and Child Health Hospital from January 2018 to October 2022 were included in the study.Basic information,physical examination,and hemoglobin detection data were collected.Descriptive analysis was used to analyze the prevalence of anemia in children in the region,and univariate analysis was used to analyze the influencing factors of anemia.RESULTS The mean hemoglobin level of infants and young children aged 9 to 36 mo increased with age,and the anemia detection rate decreased with age.The anemia detection rate in rural infants aged 6,9,and 12 mo was higher than that in urban infants.Although the anemia detection rate was higher in 6-mo-old boys than girls,it was higher in 24-mo-old girls than boys.There were statistically significant differences in the anemia detection rates among 9-mo-old and 12-mo-old infants with different nutritional statuses(emaciation,overweight,obese,and normal).Moreover,there were no statistically significant differences in anemia detection rates among infants and young children with different nutritional statuses at other ages.Besides,the anemia detection rates in obese infants aged 9 and 12 mo were higher than those in normal and overweight infants,with statistically significant differences.Finally,there were no statistically significant differences in the anemia detection rates between emaciation infants and those with other nutritional statuses.CONCLUSION The anemia situation among infants and young children aged 6 to 36 mo in Ma'anshan City,China,is relatively prominent and influenced by various factors.Our result shown that attention should be paid to the anemic infant and young child population,with strengthened education and targeted prevention and dietary guidance to help them establish good living habits,improve nutritional status,and reduce the occurrence of anemia to improve children's health levels.
文摘Background: Anemia is one of the most prevalent complications during pregnancy. It is commonly considered a risk factor for poor pregnancy outcomes and can result in complications that threaten the life of both mother and fetus, such as preterm birth, and low birth weight. There is clear evidence to support prompt treatment in all patients with iron deficiency anemia because it is known that treatment improves quality of life and physical condition as well as alleviates fatigue and cognitive deficits. Objective: The aim of the study was to evaluate the value of addition of vitamin B6 to iron in treatment of iron deficiency anemia in pregnant women during the second trimester. Patients and Methods: The study was done by giving anemia pregnant women iron therapy and vitamin B6 which represent group A and iron therapy alone which represents group B. For each pregnant woman, age, parity and gestational history were taken before treatment. All pregnant women took their allocated treatment regularly for three weeks after diagnosis of iron deficiency anemia with complete blood picture and followed up after three weeks. Results: Results of the study revealed that there was no statistically significant difference between the two groups of therapy according to the hemoglobin level before treatment (p-value = 0.734), statistically significant higher mean value in after treatment than before treatment (p-value = 0.048), there was a significant difference in the rate of change of hemoglobin (p-value = 0.011) and body mass index (p-value 0.001). Conclusion: Iron and vitamin B6 seems to increase hemoglobin level more than iron only. Thus, in pregnant women with iron deficiency anemia iron plus vitamin B6 may be considered as a more effective alternative treatment than iron only.
