Utilising continuous glucose monitoring for glycemic control in diabetic kidney disease

In this editorial,we comment on the article by Zhang et al.Chronic kidney disease(CKD)presents a significant challenge in managing glycemic control,especially in diabetic patients with diabetic kidney disease undergoing dialysis or kidney transplantation.Conventional markers like glycated haemoglobin(HbA1c)may not accurately reflect glycemic fluctuations in these populations due to factors such as anaemia and kidney dysfunction.This comprehensive review discusses the limitations of HbA1c and explores alternative methods,such as continuous glucose monitoring(CGM)in CKD patients.CGM emerges as a promising technology offering real-time or retrospective glucose concentration measure-ments and overcoming the limitations of HbA1c.Key studies demonstrate the utility of CGM in different CKD settings,including hemodialysis and peritoneal dialysis patients,as well as kidney transplant recipients.Despite challenges like sensor accuracy fluctuation,CGM proves valuable in monitoring glycemic trends and mitigating the risk of hypo-and hyperglycemia,to which CKD patients are prone.The review also addresses the limitations of CGM in CKD patients,emphasizing the need for further research to optimize its utilization in clinical practice.Altogether,this review advocates for integrating CGM into managing glycemia in CKD patients,highlighting its superiority over traditional markers and urging clinicians to consider CGM a valuable tool in their armamentarium.

Influence of Haptoglobin and Hemoglobin Phenotypic Polymorphisms on Sickle Cell Disease Morbidity

Objectives: Sickle cell disease (SCD) has a varied clinical and biological expression depending on the hemoglobin phenotype: SSFA2, SFA2, SAFA2 and SC. Considering the antioxidant properties of the different haptoglobin phenotypes (Hp 1-1, Hp 2-1, Hp 2-2), it seemed relevant to know their influence on the morbidity of the different hemoglobin phenotype of SCD. Thus, the objective of this study was to identify associations between haptoglobin phenotype and morbidity of different SCD phenotypes. Methods: In a retrospective cross-sectional descriptive and analytical study, with a cohort of 170 black African carriers of hemoglobin S, in Ivory Coast, West Africa, hemoglobin and haptoglobin phenotypes were determined by electrophoretic methods. Results: The three major phenotypes of haptoglobin polymorphism were found in the SCD cohort: Hp 1-1 (24.1%), Hp 2-1 (56.5%), Hp 2-2 (19.4%). Vaso-occlusions were associated with haptoglobin phenotype Hp 1-1, (OR = 2.03;CI95% = [1.06 - 3.9];p Conclusions: Haptoglobin phenotype was associated to morbidity-adjusted hemoglobin phenotype. The study revealed a greater probability of a worse morbidity when the hemoglobin phenotype is homozygous. Unexpectedly, the worse morbidity is associated to Hp 1-1 haptoglobin phenotype, the most powerful antioxidant within the different haptoglobin phenotypes. Associations found were not systematic and need further studies to enlighten the determinism of SCD morbidity.

Usefulness of fecal lactoferrin and hemoglobin in diagnosis of colorectal diseases

AIM:To evaluate prospectively usefulness of fecal lactoferrin(Lf)and fecal hemoglobin(Hb)in the diagnosis of colorectal diseases.METHODS:Fecal Lf and Hb were measured using ELISA in 872 patients before they underwent colorectal endoscopy.RESULTS:Lf was positive in 18(50%)of 36 patients with colorectal cancer,25(15.9%)of 157 with colorectal polyps,29(46.8%)of 62 with ulcerative colitis,and 25(62.5%)of 40(62.5%)with Crohn's disease.The Hb-positive rates were 50%,12.1%,41.9% and 32.5%,respectively.Of the 318 patients free of abnormalities by colorectal endoscopy,Lf was positive in 29(9.1%)and Hb was positive in 15(4.7%).Among patients with Crohn's disease,the Lf-positive rate was significantly higher than the Hb-positive rate.If either high Lf or Hb levels were considered positive,the positive rates rose to 61.1%,51.6%,and 67.5% in the colorectal cancer group,ulcerative colitis group,and Crohn's disease group,respectively.If both high Lf and Hb levels were rated positive,the positive predictive values(PPV)were 21% for colorectal cancer,33% for ulcerative colitis,and 17% for Crohn's disease,and PPV of high Hb level alone was 18%,25% and 13%,respectively.CONCLUSION:Fecal Lf and Hb were found useful in the detection of colorectal diseases,and the combination of the two measurements appears to increase the sensitivity and efficacy of diagnosis.

Aqueous Extract of Ceiba pentandra Stimulates the Production of Fetal Hemoglobin in Sickle Cell Patients

Subsequent studies have demonstrated the reversed activity of the aqueous extract of Ceiba pentandra on the deformity of sickled red blood cells in hypoxia conditions. The observation which related to an in vitro study had given rise to hopes as to the management of sickle cell disease (SCD) by the use of this plant species. In this paper, the authors aimed to investigate the effect of the aqueous extract of C. pentandra on the production of fetal hemoglobin in SCD patients. The work carried out hemoglobin electrophoresis, for a period of six months, on blood samples from SCD patients who voluntarily undergone routine treatment, based on the medicinal recipe prepared from the bark of the trunk and branches of C. pentandra, in a hospital center of herbal medicines located in Kinshasa. The medicinal recipe called BEAT-SS is a patented product of the hospital center named Centre de Phytothérapie Moderne NIECA. Blood samples from patients under treatment were taken to evaluate the behavior of different forms of hemoglobin (hemoglobin S, hemoglobin F and hemoglobin A2). Agarose gel electrophoresis with integrated reading was used for the separation of the different forms of hemoglobin, as well as their dosage on each sample of sickle blood. A reduction in the proportion of hemoglobin S and an increase in the proportion of fetal hemoglobin were found in all sickle cell patients during the treatment period. This observation could affirm that the management of sickle cell patients using the recipe prepared from the aqueous extract of C. pentandra could increase the level of fetal hemoglobin in these patients.

Methemoglobinemia—A biomarker and a link to ferric iron accumulation in Alzheimer’s disease

Understanding the mechanism of oxidative stress is likely to yield new insights regarding the pathogenesis of Alzheimer’s disease (AD). Our earlier work focused on the difference between hemoglobin and methemoglobin degradation, respectively leading to ferrous (Fe2+) iron, or ferric (Fe3+) iron. Methemoglobin has the role of carrier, the donor of cytotoxic and redox-active ferric (Fe3+) iron, which can directly accumulate and increase the rate of capillary endothelial cell apoptosis, and may cross into the brain parenchyma, to the astrocytes, glia, neurons, and other neuronal cells (neurovascular unit). This supposition helps us to understand the transport and neuronal accumulation process of ferric iron, and determine how iron is transported and accumulated intracellularly, identifiable as “Brain rust”. Earlier research found that the incidences of neonatal jaundice (p = 0.034), heart murmur (p = 0.011) and disorders such as dyslalia and learning/memory impairments (p = 0.002) were significantly higher in those children born from mothers with methemoglobinemia. Our hypothesis suggests that prenatal iron abnormalities could lead to greater neuronal death, the disease ageing process, and neurodegenerative disorders such as AD and other neurodegenerative diseases.

Hemoglobin Subunit Beta Gene Polymorphism rs33949930 T>C and Risk of Sickle Cell Disease—A Case Control Study from Tabuk (Northwestern Part of Saudi Arabia)

Background: Sickle cell disease and sickle cell trait are common erythrocyte disorders that are most often caused by a point mutation (rs334, designated HbS) in the hemoglobin beta gene (HBB);however of this fact, there is extreme variability in occurrence and clinical presentation of sickle cell disease which may be explained by some other genetic changes associated with the gene. In the present study we examined the association between HBB gene polymorphism rs33949930 T>C in the occurrence of sickle cell disease in Saudi Arabia population. Materials and Methods: A case control study of 100 sickle cell disease patients and 100 healthy controls from Tabuk, Saudi Arabia. HBB gene rs33949930 T>C polymorphism was analyzed using Allele specific polymerase chain reaction technique. Results: It was observed that the genotype percentages TT, TC and CC among the patients with sickle cell disease were 63.0%, 35.0% and 2.0% and healthy controls were 68.0%, 27.0% and 5.0% respectively. Allele frequency for T allele was observed to be fT = 0.20 and fT = 0.19, where as for C allele was fC = 0.80 and fC = 0.81 among cases and controls respectively (p = 0.29). Compared to the TT genotype, the odds ratio of 1.4 (95% CI 0.76 - 2.57), risk ratio of 1.2 (95% CI 0.86 - 1.65) and risk difference of 8.4 (-6.66 - 23.38) for heterozygous genotype of HBB rs33949930 T>C was observed in relation to sickle cell disease. In addition, some difference in the laboratory values was observed among sickle cell disease patients with the different variants of HBB gene rs33949930 T>C polymorphism, especially the carriers of heterozygous TC genotype;however, the difference doesn’t reach to statically significant number. Conclusion: Present study suggested that there was not any significant association between HBB gene rs33949930 T>C polymorphism and occurrence of sickle cell disease. However, the heterozygous TC genotype of the polymorphism showed some higher ratios among cases as compared to healthy control group.

Impact of chronic disease self-management programs on type 2 diabetes management in primary care

AIM: To assess the effectiveness of the Chronic Disease Self-Management Program(CDSMP) on glycated hemoglobin A1c(HbA1c) and selected self-reported measures.METHODS: We compared patients who received a diabetes self-care behavioral intervention, the CDSMP developed at the Stanford University, with controls whoreceived usual care on their HbA1c and selected self-reported measures, including diabetes self-care activities, health-related quality of life(HRQOL), pain and fatigue. The subjects were a subset of participants enrolled in a randomized controlled trial that took place at seven regional clinics of a university-affiliated integrated healthcare system of a multi-specialty group practice between January 2009 and June 2011. The primary outcome was change in HbA1c from randomization to 12 mo. Data were analyzed using multilevel statistical models and linear mixed models to provide unbiased estimates of intervention effects.RESULTS: Demographic and baseline clinical characteristics were generally comparable between the two groups. The average baseline HbA1c values in the CDSMP and control groups were 9.4% and 9.2%, respectively. Significant reductions in HbA1c were seen at 12 mo for the two groups, with adjusted changes around 0.6%(P < 0.0001), but the reductions did not differ significantly between the two groups(P = 0.885). Few significant differences were observed in participants' diabetes self-care activities. No significant differences were observed in the participants' HRQOL, pain, or fatigue measures.CONCLUSION: The CDSMP intervention may not lower HbA1c any better than good routine care in an integrated healthcare system. More research is needed to understand the benefits of self-management programs in primary care in different settings and populations.

Is nonalcoholic fatty liver disease the hepatic expression of the metabolic syndrome?

Nonalcoholic fatty liver disease(NAFLD) is generally considered as the hepatic manifestation of the metabolic syndrome(MS).Although there is no doubt that NAFLD is tightly linked to the MS,the diagnosis of NAFLD encompasses a broad range of histological entities and as a composite phenotype may be hindering attempts to understand the mechanistic basis of these variants.The awareness that NAFLD is not solely and invariably associated with the MS is a useful means to help direct future studies.We should be aware that mechanisms other than insulin resistance may contribute to the chronic inflammatory processes that underpin the development of liver fat accumulation and the subsequent architectural distortion of the liver.Further studies with special focus on hemoglobin as a risk factor for the development of NAFLD in the absence of MS should be performed.

Diabetes Mellitus in Very Elderly Russian Patients with Coronary Artery Disease

Background: Conflicting data are available on prevalence and characteristics of diabetes mellitus in very elderly patients and centenarians;therefore, we evaluated features of this pathology in patients with coronary artery disease (CAD) over 75 years old. Material and Methods: 580 patients with CAD over 75 years old were enrolled in the study on the prevalence of diabetes mellitus. 190 patients with CAD and diabetes mellitus were included in the cross-sectional study of the diabetes mellitus characteristics in old age: 153 very elderly patients (mean age—85.7 ± 4.7 years)—in the main group, 37 patients < 70 years old—in the comparison group. Toassess the condition of patients, standard clinical and laboratory methods for coronary artery disease and diabetes mellitus were used. 24-hour plasma glucose profile and hemoglobin A1c (HbA1c) level were evaluated in all patients with diabetes mellitus. Results: Diabetes mellitus or impaired glucose tolerance was found in 22.2% of very elderly patients with CAD. Glucose levels in very elderly diabetic patients were lower at all time points than in patients < 70 years old. The largest differences were recorded for the blood glucose concentration at 6 a.m. (p = 0.00005). Glucosuria was registered in 29.7% of patients aged 51 - 69 years, while among elderly patients—in 11.1% (p = 0.004). The mean levels of HbA1c were 7.3% and 8.7%, respectively (p = 0.01). Correlation analysis revealed negative correlation between the age of patients and the glucose level (r = ?0.4, p = 0.00002—for 6 AM glucose). The mean body mass in-dex in very elderly patients was 30.8 ± 5.8 kg/m2, in patients < 70 years old—33.9 ± 6.5 kg/m2 (p = 0.03). Significant differences between the groups of very elderly and younger patients were registered in terms of triglycerides (1.65 and 3.57 mmol/L, respectively, p < 0.00001), HDL-cholesterol (1.16 and 0.87 mmol/L, respectively, p = 0.03) and ath-erogenic index (3.45 and 6.73, respectively, p = 0.002). Conclusion: The study results indicate that diabetes mellitus is often diagnosed in very elderly patients with CAD. In very elderly patients, lower values of blood glucose, hemoglobin A1c and glucosuria are recorded, compared with younger patients with diabetes mellitus.

Anemia in Juvenile Idiopathic Arthritis (JIA) and Other Pediatric Rheumatologic Diseases: A Retrospective Study

Objectives: The present study estimated the prevalence of anemia among children and adolescents with pediatric rheumatological diseases in a referral center, and analyzed the associated clinical and biological parameters. Methods: A retrospective chart review included 49 children with rheumatological diseases, who were diagnosed by a pediatric rheumatologist and classified according to the International League of Associations for Rheumatology (ILAR) guidelines and criteria endorsed by the American College of Rheumatologists. Anemia was defined as hemoglobin level lower than the 5th centile for the corresponding age and gender. Disease activity was indicated by serum levels of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), where available. Results: Participants were aged 2 - 18 years (mean ± SD = 10.41 ± 4.23 years), 38 (77.6%) of them had JIA, and 8 (16.3%) had systemic lupus erythematosus. The most frequent subtype of JIA was the polyarticular (16 out of 38, 42.1%), followed by systemic (14, 36.8%). The prevalence of anemia was 46.9% (95% CI = 32.5% - 61.7%), with no significant difference between JIA and other diseases or between the different JIA subtypes. Nevertheless, anemia was more frequently observed in younger patients (age 2 - 6 years: 69.2% vs <48%) and those with elevated ESR (68.8% vs 33.3%) or CRP (60.0% versus 45.2%), compared with their counterpart respectively;however, only the association with ESR was statistically significant (p = 0.049). No agreement was found between CRP and ESR (Kappa = 0.140). Conclusion: Anemia is frequent in JIA and other rheumatologic diseases in children, concerning approximately 50% of the patients and responding to anemia of inflammation as the major pathophysiological mechanism. Further research is warranted to provide more accurate insight into the pathophysiological mechanisms and clinical characteristics of anemia in pediatric rheumatological disease and to measure its morbidity, to provide efficient and evidence-based management strategies.

Red blood cell level is increased in obese but not in non-obese patients with coronary heart disease

Objective To examine the changes of red blood cell levels in the obese and non-obese patients with coronary heart disease （CHD） and its clinical significance. Methods 230 cases of coronary heart disease were selected and divided into the obese group and the non- obese group. Obesity and non-obesity were defined based on the body mass index （BMI if 28.0kg/m2）, or waist-hip ratio （men〉 0.9, women〉 0.85）. In addition, 130 healthy subjects were recruited as controls. The pathological status of coronary lesions was quantita- tively analyzed according to the Coronary Vascular Image Segmentation Evaluation Criteria （American Heart Association 1984） and the Gensini scoring system. Results of the changes of both the hemoglobin levels and the red blood cell count in the obese group, the non- obese group with CHD and the control group were compared. Besides, Multivariant Logistic Regression Analysis was applied to assess the correlation between the red blood cells and the coronary artery disease. Results The red blood cell count and the level of hemoglobin in the obese group with CHD was higher than that in the non-obese group with CHD [（4.35 ± 0,55） and （4.13 ± 0.56） 10^9/L; （136.71± 15.87） and （129.96 ±16.23） g/L, P 〈 0.05 in both]; the proportion of acute coronary syndrome in the obese group with CHD was higher in the obese group with CI-/D than that in the non-obese group with CHD （P〈0.05）; Multivariant logistic regression analysis also showed that the red blood cell count was positively correlated with obesity with CHD.Conclusion The red blood cell count and the level of hemoglobin in the obese group were higher than those in the non-obese group; the increase of red blood cell count and hemoglobin level is one of the independent risk factors for the obese patients with CHD.

Association between restrictive pulmonary disease and type 2 diabetes in Koreans:A cross-sectional study

BACKGROUND Diabetes is a progressive disease that increases glucose levels in the blood.While studies have shown that patients with pulmonary disease(both obstructive and restrictive pulmonary disease)have a higher prevalence of type 2 diabetes mellitus(T2DM),there have been more studies on restrictive patterns than chronic obstructive pulmonary disease.AIM To assess whether restrictive and obstructive pulmonary diseases are associated with T2DM in Koreans.METHODS For our analysis,we used data from the Korea National Health and Nutrition Examination Survey.A total of 2830 subjects were included in this study.Spirometry results were categorized into three patterns:Normal,restrictive pulmonary disease(RPD),and obstructive pulmonary disease(OPD).RESULTS The factors used as diabetic indicators(i.e.homeostatic model assessment of insulin resistance,homeostatic model assessment of beta-cell function,glycated hemoglobin,and fasting insulin)were among the highest in RPD but not in OPD.Based on multivariate logistic regression analysis,subjects with RPD were found with an increased odds ratio[OR:1.907,95%confidence interval(CI):1.110-3.277]for T2DM compared with subjects with normal pulmonary function,whereas in patients with OPD,the OR had not increased.Model 4,which adjusted for the variables that could affect diabetes and pulmonary disease,showed a significant increase in the T2DM OR to RPD(OR:2.025,95%CI:1.264-3.244).On the other hand,no statistically significant difference was shown in OPD(OR:0.982,95%CI:0.634-1.519).CONCLUSION RPD,not OPD,is highly associated with T2DM regardless of the risk factors of various T2DMs that can be confounds.

Prognostic Significance of HbA1c Level in Asian Patients with Prediabetes and Coronary Artery Disease

Background:Measuring glycosylated hemoglobin(HbA1c)is a simple way to assess patients with prediabetes or diabetes mellitus.It has been shown that HbA1c level predicts prognosis in patients with coronary artery disease(CAD)and the incidence of diabetes mellitus.However,the prognostic significance of HbA1c level in Asian patients with prediabetes and CAD is not yet clear.Our study aimed to determine the relationship between HbA1c level and major adverse cardiovascular events(MACE)in patients with prediabetes and CAD.Methods:We enrolled 1367 patients with prediabetes and CAD in the final analysis,and grouped them according to the HbA1c level.Primary end points included nonfatal myocardial infarction,hospitalization for unstable angina,and ischemia-driven revascularization.Cox proportional-hazards regression analysis was used to determine the relation-ship between HbA1c level and MACE after our accounting for confounding factors.Results:A total of 1367 patients(age 58.8±10.3 years;71.6%men)were included.During 43 months of follow-up,197 patients experienced at least one primary end point event.Multivariate Cox proportional-hazards regression analy-sis showed in comparison of HbA1c levels that the hazard ratio for primary end points was 4.110,with a 95%confidence interval of 2.097-6.011(P<0.001).Conclusions:HbA1c level positively correlated with MACE,demonstrating it is a valuable indicator for indepen-dently predicting MACE in Asian patients with prediabetes and CAD.

Prevalence of nonalcoholic fatty liver disease and its association with age in patients with type 2 diabetes mellitus

BACKGROUND Type 2 diabetes mellitus(T2DM)is a risk factor for nonalcoholic fatty liver disease(NAFLD).AIM To determine the prevalence and clinical correlates of NAFLD in a large cohort of patients with T2DM.METHODS Four hundred thirty-seven participants with T2DM who consulted at Meijo Hospital from April 2019 to September 2020 and underwent computed tomography(CT)were assessed.The mean age was 74±13 years,and 269 were men.Hepatic attenuation minus splenic attenuation(CTL−S)less than 1 Hounsfield unit was considered fatty liver.NAFLD was defined as fatty liver in the absence of significant alcohol consumption and hepatitis virus infection.A multiple logistic regression was used to assess the independent factors associated with NAFLD.RESULTS NAFLD was identified in 25.2%of the participants.Young age(odds ratio[OR]=−0.945;95%confidence interval[CI]:0.922–0.969),higher hemoglobin levels(OR=1.501,95%CI:1.278–1.764),lower high-density lipoprotein(HDL)cholesterol levels(OR=0.971,95%CI:0.953–0.989),and the absence of dialysis(OR=0.109,95%CI:0.014–0.856)were independent predictors of NAFLD.CONCLUSION NAFLD was detected with CT in 25.2%of the participants.NAFLD was associated with younger age,higher hemoglobin levels,lower HDL cholesterol levels,and an absence of dialysis.

Systematic Screening of Neonatal Sickle Cell Disease with HemoTypeSC^(TM)-Test: Case Study and Literature Review

emoTypeSC? test is a new cheap, faster, and appropriate screening method for neonatal diagnosis of sickle cell disease. The literature reports a few cases of its applicability. This study extends the cases study and reviews the available literature. The sample consisted of 99 subjects, including 87 newborns (36 girls and 51 boys;1.9 - 4.9 kg BW) sampled among 566 babies bone at six hospitals in Kisangani city (Democratic Republic of Congo) during March-April 2019;height infant-adolescents (<18 years);and four adults. Duplicate blood samples of 75 newborns, spotted on filter paper, were transferred to Liège in Belgium for LC-MS test confirmation. Of 99 subjects, 74.74% tested HbAA, 24.26% HbAS and 1% HbSS. The prevalence of HbAS compared to the HbAA phenotype was 15/60 (20%) by HemoTypeSC? and 14/61 (18.7%) by LC-MS. The concordance between the two methods was 98.3% or a discordance of 1.7%. The findings support the validity of the HemoTypeSC? test as a sensitive, specific point of care test, cheap and reliable for poor African populations.

红细胞分布宽度、糖化血红蛋白水平与不稳定型心绞痛患者冠状动脉病变程度及狭窄程度的相关性分析

目的分析红细胞分布宽度、糖化血红蛋白水平与不稳定型心绞痛患者冠状动脉病变程度及狭窄程度的相关性。方法120例不稳定型心绞痛患者,根据冠状动脉病变支数的不同分为单支病变组(60例)、双支病变组(40例)、多支病变组(20例),根据冠状动脉狭窄程度的不同分为轻度狭窄组(50例)、中度狭窄组(40例)、重度狭窄组(20例)、完全闭塞组(10例)。对比不同冠状动脉病变支数组和狭窄程度组的红细胞分布宽度、糖化血红蛋白水平;使用Pearson法分析红细胞分布宽度、糖化血红蛋白水平与不稳定型心绞痛患者冠状动脉病变支数、冠状动脉狭窄程度的相关性。结果单支病变组、双支病变组、多支病变组的红细胞分布宽度分别为(9.27±0.71)%、(12.59±1.36)%、(17.87±2.68)%,糖化血红蛋白分别为(6.57±1.12)%、(8.89±2.06)%、(12.65±3.18)%。单支病变组、双支病变组、多支病变组的红细胞分布宽度、糖化血红蛋白水平对比,差异均有统计学意义(P<0.05);且红细胞分布宽度、糖化血红蛋白水平从高到低分别均为:多支病变组>双支病变组>单支病变组,差异均有统计学意义(P<0.05)。轻度狭窄组、中度狭窄组、重度狭窄组、完全闭塞组的红细胞分布宽度分别为(8.71±0.63)%、(11.86±0.92)%、(15.76±1.78)%、(20.36±3.04)%,糖化血红蛋白分别为(5.47±1.15)%、(6.97±1.83)%、(9.22±2.68)%、(14.86±3.89)%。轻度狭窄组、中度狭窄组、重度狭窄组、完全闭塞组的红细胞分布宽度、糖化血红蛋白水平对比,差异均有统计学意义(P<0.05);且红细胞分布宽度、糖化血红蛋白水平从高到低分别均为:完全闭塞组>重度狭窄组>中度狭窄组>轻度狭窄组,差异均有统计学意义(P<0.05)。Pearson分析法显示,不稳定型心绞痛患者冠状动脉病变支数的多少与红细胞分布宽度、糖化血红蛋白水平之间呈正相关(r=0.25、0.15,P<0.05);不稳定型心绞痛患者冠状动脉狭窄程度的轻重与红细胞分布宽度、糖化血红蛋白水平之间呈正相关(r=0.49、0.65,P<0.05)。结论临床可以通过红细胞分布宽度、糖化血红蛋白水平的血清学检测来评估不稳定型心绞痛患者冠状动脉病变支数和狭窄程度,进而根据患者病情的轻重来指导临床治疗,从而使患者获得更好的预后。

血清CXCL9、sCD163、SP-D含量在老年慢性阻塞性肺疾病急性加重期近期预后中的预测价值

目的分析血清CXC趋化因子配体9(CXCL9)、可溶性血红蛋白清道夫受体163(sCD163)、肺表面活性蛋白D(SP-D)含量在老年慢性阻塞性肺疾病急性加重期(AECOPD)近期预后中的预测价值。方法回顾性分析2021年4月至2023年4月在榆林市第一医院进行治疗的110例老年AECOPD患者的临床资料。依据随访3个月的预后情况,分为预后良好组(n=75)、预后不良组(n=35)。比较两组基线资料,通过多因素Logistic回归分析老年AECOPD近期预后不良的危险因素,采取非条件Logistic逐步回归分析受试者操作特征(ROC)曲线预测急性生理与慢性健康评分Ⅱ(APACHEⅡ)、血清CXCL9、sCD163、SP-D老年AECOPD近期预后的价值。结果预后不良组APACHEⅡ评分、血清CXCL9、sCD163、SP-D水平分别为(25.47±6.52)分、(12.16±3.21)pmol/L、(145.56±30.12)pg/mL、(137.21±35.47)μg/L,均高于预后良好组[(17.42±5.84)分、(9.45±3.12)pmol/L、(104.54±25.37)pg/mL、(113.45±30.67)μg/L],差异均有统计学意义(P<0.05)。多因素Logistic回归分析证实,APACHEⅡ评分、血清CXCL9、sCD163、SP-D是老年AECOPD近期预后不良的危险因素,均有P<0.05;经ROC曲线分析证实APACHEⅡ评分、血清CXCL9、sCD163、SP-D均可用于老年AECOPD近期预后的预测,曲线下面积分别为0.723、0.821、0.815、0.840,均有较高预测价值(P<0.05)。结论血清CXCL9、sCD163、SP-D水平升高将增加老年AECOPD患者近期预后不良风险,可将以上指标用于预测老年AECOPD患者近期预后,可获得较高敏感度与特异度。
