Abstract
Background Diabetic neuropathy (DN) is a common complication of type 2 diabetes (T2DM) and is characterized by persistent inflammation. Hematological parameters have emerged as a novel marker for detecting chronic inflammatory conditions, including diabetes. Aim We aim to examine the association between HbA1c levels, which can indicate the presence of diabetic neuropathy, and hematological parameters to explore the possibility of using hematological parameters as a new indicator for DN in T2DM patients. Methods This was a retrospective study of 768 (483 males and 284 females) medical records of adult T2DM patients with or without neuropathy who attending the outpatient neuromuscular clinic at King Abdul-Aziz University Hospital from January 2016 to December 2021. Results The results showed significant increases in HbA1c levels (p=0.000), lymphocyte levels (p=0.028), and the neutrophil-lymphocyte ratio (NLR) (p=0.011). In the T2DM group, HBA1C levels were found to be positively correlated with age (r=0.306, p=0.000), neutrophil (NEUT) (r=0. 287, p=0.000), platelet (PLT) (r=0. 148, p=0.039), and neutrophil-lymphocyte ratio (NLR) (r=0.306193, p=0.0007), and negatively correlated with gender (r=-0.306193, p=0.0007). In the T2DMN group, HBA1C levels showed a positive correlation with hemoglobin (HB) (r=0.084, p=0.045), PLT (r=0.087, p=0.037), and PLT/mean corpuscular hemoglobin (MCH) ratio (PLT/MCH ratio) (r=0.12, p=0.004), and a negative correlation with age (r=-0.204, p=0.000), gender (r=-0.086, p=0.041), weight (WT) (r=-0.113, p=0.007), Body Surface Area (BSA) (r=-0.09, p=0.031), mean corpuscular volume (MCV) (r=-0.292, p=0.000), and MCH (r=-0.186, p=0.000). Conclusion Our study found a significant association between HbA1c, a biomarker for diabetic neuropathy, and various hematological parameters (HB, MCV, MCH, PLT, PLT/MCH ratio) in T2DMN patients. By effectively controlling and monitoring these variables, it may be feasible to prevent or delay the progression of peripheral neuropathy in diabetic patients. However, further research is needed to validate these findings.

Sci Rep 2023; 13:1292. [PMID: 36690679 PMCID: PMC9869811 DOI: 10.1038/s41598-022-27304-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 12/29/2022] [Indexed: 01/25/2023] Open
Abstract
Human metallothionein-2A (MT2A) protein participates in metal homeostasis, detoxification, oxidative stress reduction, and immune defense. It decreases heavy metal ions and reactive oxygen species (ROS) during injury of cells and tissues. The single nucleotide polymorphisms at the MT2A gene have been associated in various human diseases including cancer. The current study aimed to elucidate associations between MT2A genotypes with the clinical, biochemical, and molecular characteristics that potentially related to lowered MT2A ex-pression. One hundred and forty-one healthy Taiwanese subjects were enrolled from Changhua Show-Chwan Memorial Hospital. Clinical, biochemical and molecular characteristics including the frequent minor allele SNPs, rs28366003 and rs10636, within the MT2A gene were determined. The genotype distribution of MT2A rs10636 fits the Hardy-Weinberg equilibrium. The significant associations with gradually decline of mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were identified with MT2A rs10636 and rs28366003 using analysis of variance (ANOVA) with Tukey's analysis as a post hoc test. We further validated the correlations between the expressions of genes in erythropoiesis, cholesterol synthesis, platelet synthesis, insulin with MT2A using the web-based Gene Expression Profiling Interactive Analysis (GEPIA) databases. The results revealed that hypoxia-inducible factor 1α (HIF-1α), erythropoietin (EPO), lipoprotein lipase (LPL), and lecithin-cholesterol acyltransferase (LCAT) mRNA ex-pression are significantly correlated with MT2A mRNA expression. In conclusion, these results suggested that genetic variations of MT2A rs10636 and rs28366003 might be an important risk factor for erythropoiesis in the Taiwanese general population.

Genome-Wide Association Study on the Hematological Phenotypic Characteristics of the Han Population from Northwest China. Pharmgenomics Pers Med 2022; 15:743-763. [PMID: 35945964 PMCID: PMC9357418 DOI: 10.2147/pgpm.s361809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 06/14/2022] [Indexed: 11/23/2022] Open
Abstract
Background Hematological characteristics have positive reference value as clinical indicators in the evaluation of various diseases. The purpose of this study was to determine the gene loci associated with 20 hematological phenotypes in the Han population from northwest China. Methods A genome-wide association study (GWAS) was conducted on hematological indicators of 1005 Han people from northwest China. Genotyping was performed with a GeneTitan multichannel instrument and Axiom Analysis Suite 6.0. Using the 1000 Genomes Project (phase 3) as a reference, haplotype imputation was performed with IMPUTE2. SNVs (single nucleotide variants) significantly associated with hematological phenotypes were identified. The top SNV (p < 5E-7) was then selected for replication detection. Results Ninety genetic variations identified in the GWAS were significantly associated with hematological indicators. Among them, only rs35289401 (CCDC157) was significantly associated (genome-wide) with red blood cell distribution width (RDW) (p = 4.21E-08). The fourteen top SNVs were selected for replication verification and were significantly associated with hematological phenotypes. However, only HBS1 L-MYB rs1331309 was significantly associated with the mean hemoglobin content (p = 6.42E-07). We also found that the mean corpuscular hemoglobin (MCH) level in the rs1331309 GG/GT genotype was significantly higher than that in the TT genotype (p = 0.023). Conclusion The GWAS identified a total of 90 genetic variants significantly associated with hematological phenotypic indicators. In particular, rs1331309 (HBS1 L-MYB) is expected to be a biomarker for monitoring the dynamics of MCH levels. This study provides a reference for related studies on the genetic structure of hematological characteristics. It provides a valuable reference for the clinical diagnosis or prediction of a variety of diseases.

Cardiovascular Risk Factors and Haematological Indexes of Inflammation in Paralympic Athletes with Different Motor Impairments. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:6798140. [PMID: 31827693 PMCID: PMC6885819 DOI: 10.1155/2019/6798140] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 10/30/2019] [Indexed: 12/16/2022]
Abstract
Haematological indexes of both inflammation and platelet activation have been suggested as predictive markers of cardiovascular disease (CVD), which has high prevalence in Paralympic athletes (PA). Different mechanisms could play a role in increasing CVD risk in PA with spinal cord injury (PA-SCI), lower limb amputation (PA-LLA), or upper limb impairment (PA-ULI). We compared, in 4 groups of PA competing in power, intermittent (mixed metabolism), and endurance sports, Framingham Risk Score (FRS), metabolic syndrome criteria (MetS-C), inflammation (INFLA) Score, 5 haematological indexes of platelet activation (mean platelet volume (MPV), platelet distribution width (PDW), and the ratios between MPV and platelet (MPVPR), between MPV and lymphocyte (MPVLR), and between PDW and lymphocyte (PDWLR)) and the endogenous antioxidants uric acid (UA) and bilirubin (BR). A retrospective chart review of PA from preparticipation examinations' records (London 2012 and Sochi 2014 Paralympics) was performed. We included 25 PA-SCI (13 with high and 12 with low lesion, PA-SCI-H and PA-SCI-L), 15 PA-LLA, and 10 PA-ULI. FRS and INFLA Score did not differ among groups, but PA-SCI-H had lower HDL, compared to PA-SCI-L and PA-ULI. PA-LLA had more MetS diagnostic criteria with significant higher glucose levels than other groups. PA-SCI-H had significantly lower lymphocytes' count compared to PA-LLA and higher MPV, PDW, MPVPR, MPVLR, and PDWLR. SCI-H had lower BR, haemoglobin, haematocrit, proteins, and creatinine. No interaction was found between the 3 kinds of sitting sports and the 2 groups of health conditions (PA-SCI and PA-LLA). In conclusion, PA-LLA had a higher cardiometabolic risk, whereas PA-SCI-H had a higher platelet-derived cardiovascular risk. Further larger studies are needed to investigate the relationship between indexes of inflammation/oxidation and dietary habit, body composition, and physical fitness/performance in PA with motor impairments.

Abstract
OBJECTIVE Nutritional deficiencies are very significant to the overall health of humans at all ages and for both genders, yet in infants, children and women of childbearing age these deficiencies can seriously affect growth and development. The present work is aimed to assess homocysteine and vitamin B12 status in females with iron deficiency anemia from the Gaza Strip. METHODS Venous blood samples were randomly collected from 240 female university students (18-22 years old) and parameters of the complete blood count, serum ferritin, homocysteine and vitamin B12 were measured. Statistical analysis included the t-test and analysis of variance (ANOVA) using the IBM SPSS software (version 18). Statistical significance was set for p-values <0.05. RESULTS The results revealed that 20.4% of the students have iron deficiency anemia. The mean serum vitamin B12 level in females with iron deficiency anemia (212.9±62.8pg/mL) was significantly lower than in normal controls (286.9±57.1pg/mL) and subjects with microcytic anemia and normal ferritin (256.7±71.1pg/mL). Significantly higher serum homocysteine levels were reported in the iron deficiency anemia group (27.0±4.6μmol/L) compared to normal controls (15.5±2.9μmol/L) and in subjects with microcytic anemia and normal ferritin (18.1±2.7μmol/L). Statistically significant negative correlations were reported for serum homocysteine with serum ferritin, vitamin B12, hemoglobin, and hematocrit levels. CONCLUSION Important associations were found between serum homocysteine and markers of iron deficiency. Monitoring homocysteine levels might be essential to understand the development of different clinical conditions including anemia. It seems necessary to conduct prospective trials to determine whether treating anemia ameliorates homocysteine levels.

Abstract
Macrocytosis, the hallmark of cobalamin/folate deficiency anemia, is frequently absent. Clinicians have to be aware of coexisting conditions that can mask the macrocytosis expression of megaloblastic anemia, especially iron deficiency. The objective of this work was to investigate the degree of overlap between iron deficiency anemia (IDA) and cobalamin deficiency and to develop a predictive model for differentiating IDA from combined deficiency. A prospective case and control study was carried out to investigate vitamin B12 and folate status in iron deficiency anemia. A total of 658 patients were recruited, 41 of whom (6.2 %) were excluded. The remaining 617 subjects consisted of 130 controls and 487 with IDA. Low vitamin B12 (LB12) was considered when serum vitamin B12 was ≤200 pmol/L. High serum homocysteine (Hcy) was defined by Hcy >17 μM/L. A multivariate analysis (including a logistic regression) was performed to develop a diagnostic model. Low vitamin B12 levels were found in 17.8 % of IDA subjects. Ten out of 11 subjects (91 %) with IDA and serum vitamin B12 (B12) ≤100 pmol/L showed vitamin B12 deficiency. Moreover, vitamin B12 deficiency was demonstrated in 48 % of cases with IDA and B12 between 101 and 150 pmol/L and in 40 % with IDA and B12 between 151 and 200 pmol/, respectively. As a result of multivariate logistic analysis, neutrophil counts and age predicted subjects with vitamin B12 ≤200 and Hcy >17 μmol/L, [Formula: see text]. Using the age of 60 as a cutoff, sensitivity was 91 % (39 out of the 43 patients with vitamin B12 deficiency and IDA were identified). In summary, low vitamin B12 was found in 18 % of patients with IDA. Vitamin B12 deficiency was demonstrated in many patients with LB12 and IDA. Age over 60 years was used to separate patients with combined deficiency (sensitivity 91 %). Therefore, for a diagnostic purpose, serum vitamin B12 should be evaluated in IDA patients over 60 years. This diagnostic model needs to be validated in a different population.
