Schwarz C, Göring J, Grüttner C, Hilger I. Intravenous Injection of PEI-Decorated Iron Oxide Nanoparticles Impacts NF-kappaB Protein Expression in Immunologically Stressed Mice. NANOMATERIALS (BASEL, SWITZERLAND) 2023; 13:3166. [PMID: 38133063 PMCID: PMC10745731 DOI: 10.3390/nano13243166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 12/01/2023] [Accepted: 12/11/2023] [Indexed: 12/23/2023]
Abstract
Nanoparticle-based formulations are considered valuable tools for diagnostic and treatment purposes. The surface decoration of nanoparticles with polyethyleneimine (PEI) is often used to enhance their targeting and functional properties. Here, we aimed at addressing the long-term fate in vivo and the potential "off-target" effects of PEI decorated iron oxide nanoparticles (PEI-MNPs) in individuals with low-grade and persistent systemic inflammation. For this purpose, we synthesized PEI-MNPs (core-shell method, PEI coating under high pressure homogenization). Further on, we induced a low-grade and persistent inflammation in mice through regular subcutaneous injection of pathogen-associated molecular patterns (PAMPs, from zymosan). PEI-MNPs were injected intravenously. Up to 7 weeks thereafter, the blood parameters were determined via automated fluorescence flow cytometry, animals were euthanized, and the organs analyzed for iron contents (atomic absorption spectrometry) and for expression of NF-κB associated proteins (p65, IκBα, p105/50, p100/52, COX-2, Bcl-2, SDS-PAGE and Western blotting). We observed that the PEI-MNPs had a diameter of 136 nm and a zeta-potential 56.9 mV. After injection in mice, the blood parameters were modified and the iron levels were increased in different organs. Moreover, the liver of animals showed an increased protein expression of canonical NF-κB signaling pathway members early after PEI-MNP application, whereas at the later post-observation time, members of the non-canonical signaling pathway were prominent. We conclude that the synergistic effect between PEI-MNPs and the low-grade and persistent inflammatory state is mainly due to the hepatocytes sensing infection (PAMPs), to immune responses resulting from the intracellular metabolism of the uptaken PEI-MNPs, or to hepatocyte and immune cell communications. Therefore, we suggest a careful assessment of the safety and toxicity of PEI-MNP-based carriers for gene therapy, chemotherapy, and other medical applications not only in healthy individuals but also in those suffering from chronic inflammation.

Abstract
Exposure to early-life adversity (ELA) and iron deficiency early in life are known risk factors for suboptimal brain and socioemotional development. Iron deficiency may arise from and co-occur with ELA, which could negatively affect development. In the present study, we investigated whether ELA is associated with iron deficiency in infants receiving no iron supplementation. This study is a secondary analysis of extant data collected in the 1990s; participants were healthy infants from working-class communities in Santiago, Chile (N = 534, 45.5% female). We measured stressful life events, maternal depression, and low home support for child development during infancy and assessed iron status when the infant was 12 months old. Slightly more than half of the infants were iron-deficient (51%), and 25.8% were iron-deficient anemic at 12 months. Results indicated that ELA was associated with lower iron levels and iron deficiency at 12 months. The findings are consistent with animal and human prenatal models of stress and iron status and provide evidence of the association between postnatal ELA and iron status in humans. The findings also highlight a nutritional pathway by which ELA may impact development and present a nutritionally-focused avenue for future research on ELA and psychopathology.

Abstract
Background Anemia is a common and often overlooked hematological change observed in patients with diabetes mellitus. However, there is no global survey or health registry that estimates the pooled prevalence of anemia in patients with type 2 diabetes. Therefore, this study aimed to determine the global pooled prevalence of anemia among adult patients with type 2 diabetes. Methods This study was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. The study protocol was registered on PROSPERO with the reference number (CRD42022327135), and the link provided (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022327135) display the published methodology. Previously published articles were searched in PubMed/Medline, Cochrane Library, WHO Global Index Medicus, African Journals Online, ScienceDirect, Google Scholar, and Google from October 26 to November 09, 2022. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal tool. Random-effects model was used to estimate the pooled prevalence of anemia. The degree of heterogeneity among the included studies was assessed using I2 statistics. Publication bias was detected using funnel plot symmetry analysis supplemented by Egger's and Begg's tests. Results Twenty-four studies with a total number of 19,118 participants were included in this systematic review and meta-analysis. The overall pooled prevalence of anemia among type 2 diabetic adult patients was 27.0% (95% CI: 24.0, 31.0, I2 = 96.45%; P< 0.001). Geographical and time-based subgroup analysis showed that higher prevalence of anemia was observed in Africa region 28.0% (95% CI: 17.0, 39.0) and from 2015 to 2022, 28.0% (95% CI: 24.0, 33.0), respectively. Conclusion Anemia is a moderate public health problem among adult patients with type 2 diabetes. Nearly one in four patients with type 2 diabetes develops anemia. Therefore, considering the negative impact of anemia, it is important to include anemia screening in the routine assessment of diabetes-related complications.

Abstract
BACKGROUND Most data on anemia in children with intestinal failure (IF) have been obtained from studies in which the data were collected at a single point in time. We aimed to identify the frequency of anemia and factors associated with hemoglobin levels in children with IF during their course of home parenteral nutrition. METHODS We performed a longitudinal cohort study of patients with IF followed up at a pediatric intestinal rehabilitation center. Outcome variables were hemoglobin levels and prevalence of anemia during the follow-up period. The exposure variables were age, duration of parenteral nutrition, chronic disease, and serum concentrations of C-reactive protein, iron, copper, selenium, vitamins A, D, B12 , and folic acid. RESULTS Twenty-five children with a median time of receiving parenteral nutrition of 40.7 months were included. A median (and interquartile range) of 40.7 (25.2-58) hemoglobin measurements were performed per patient. Mean (SD) hemoglobin was 10.7 (1.8) g/dL at baseline and 11.6 (0.9) g/dL in the last observation (paired t test, P = 0.07); 32% of patients had mean hemoglobin values below the lower limit for age. In a multivariable predictive model, having C-reactive protein >1 mg/dL was associated with a decrease of 0.57 g/dL in hemoglobin (95% CI, -0.90 to -0.24, P = 0.01), and an increase of 1 mg/L in vitamin A concentration was associated with the increase of 0.93 g/dL in Hb level (95% CI, 0.24-1.61; P = 0.008). CONCLUSION Anemia affects almost one-third of children with IF and its frequency decreases during the follow-up period. Hemoglobin levels are associated with inflammatory response and serum micronutrient concentrations.

Red Blood Cell Distribution Width: A Risk Factor for Prognosis in Patients with Ischemic Cardiomyopathy after Percutaneous Coronary Intervention. J Clin Med 2023; 12:jcm12041584.

Abstract
BACKGROUND It has been demonstrated in previous studies that red blood cell distribution width (RDW) is correlated with the severity and prognosis of cardiovascular disease. The target of our study was to assess the relationship between RDW and the prognosis of ischemic cardiomyopathy (ICM) patients undergoing percutaneous coronary intervention (PCI). METHODS The study retrospectively enrolled 1986 ICM patients undergoing PCI. The patients were divided into three groups by RDW tertiles. The primary endpoint was major adverse cardiovascular events (MACE) and the secondary endpoints were each of the components of MACE (all-cause mortality, nonfatal myocardial infarction (MI) and any revascularization). Kaplan-Meier survival analyses were conducted to show the association between RDW and the incidence of adverse outcomes. The independent effect of RDW on adverse outcomes was determined by multivariate Cox proportional hazard regression analysis. In addition, the nonlinear relationship between RDW values and MACE was explored using restricted cubic spline (RCS) analysis. The relationship between RDW and MACE in different subgroups was determined using subgroup analysis. RESULTS As RDW tertiles increased, the incidences of MACE (Tertile 3 vs. Tertile 1: 42.6 vs. 23.7, p < 0.001), all-cause death (Tertile 3 vs. Tertile 1: 19.3 vs. 11.4, p < 0.001) and any revascularization (Tertile 3 vs. Tertile 1: 20.1 vs. 14.1, p < 0.001) increased significantly. The K-M curves showed that higher RDW tertiles were related to increased incidences of MACE (log-rank, p < 0.001), all-cause death (log-rank, p < 0.001) and any revascularization (log-rank, p < 0.001). After adjusting for confounding variables, RDW was proved to be independently associated with increased risks of MACE (Tertile 3 vs. Tertile 1: HR, 95% CI: 1.75, 1.43-2.15; p for trend < 0.001), all-cause mortality (Tertile 3 vs. Tertile 1: HR, 95% CI: 1.58, 1.17-2.13; p for trend < 0.001) and any revascularization (Tertile 3 vs. Tertile 1: HR, 95% CI: 2.10, 1.54-2.88; p for trend < 0.001). In addition, the RCS analysis suggested nonlinear association between RDW values and MACE. The subgroup analysis revealed that elderly patients or patients with angiotensin receptor blockers (ARBs) had a higher risk of MACE with higher RDW. Patients with hypercholesterolemia or without anemia also had a higher risk of MACE. CONCLUSIONS RDW was significantly related to the increased risk of MACE among ICM patients undergoing PCI.

Abstract
Short stature is a common clinical condition in paediatric outpatient clinics and is associated with various clinical conditions, ranging from normal variants to severe diseases. Short stature is known to be caused by chronic inflammatory conditions, in which over-produced inflammatory cytokines are reported to be involved in growth suppression. Castleman disease is a rare lymphoproliferative disorder known as a chronic inflammatory disease with overproduction of interleukin 6, which often causes systemic symptoms such as fever, fatigue, weight loss, and night sweats. Here, we report the case of a 10-year-old female diagnosed with unicentric Castleman disease, who presented with short stature as the sole clinical sign but lacked typical systemic symptoms of Castleman disease. An elevated serum C-reactive protein level led us to suspect a chronic inflammatory condition, and we found an intra-abdominal tumour that was histopathologically confirmed as Castleman disease. The tumour removal resulted in a steady catch-up in her height in the six years following the surgery. We also present a brief review of relevant literature on paediatric cases of Castleman disease associated with growth impairment. Clinicians should be aware that chronic inflammatory conditions can cause growth impairment, which may be a key clinical manifestation of such conditions.

Impact of disease burden or inflammation on nutritional assessment by the GLIM criteria in female patients with rheumatoid arthritis. Clin Nutr ESPEN 2022; 52:353-359. [PMID: 36513475 DOI: 10.1016/j.clnesp.2022.09.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 08/13/2022] [Accepted: 09/13/2022] [Indexed: 01/28/2023]
Abstract
BACKGROUND & AIMS In 2018, the Global Leadership Initiative on Malnutrition (GLIM) released a global standard for evaluating malnutrition. The etiologies of malnutrition in the GLIM criteria includes disease burden/inflammation, but how this view affects nutritional assessment remains unclear. This study aimed to investigate the impact of disease burden/inflammation on the proportion of malnourished patients defined by GLIM criteria, and how differences in methods for determining disease burden/inflammation in GLIM criteria affect existing nutritional indices among patients with rheumatoid arthritis (RA). We also investigated factors associated with malnutrition in RA patients. METHODS Data from 135 female RA patients (66.8 ± 12.6 years) were cross-sectionally analyzed. Among the etiologies of malnutrition, disease burden/inflammation was defined as: (1) moderate or higher disease activity score (disease activity score composite of the 28-joint score and erythrocyte sedimentation rate [DAS28-ESR] ≥ 3.2) [DAS-malnutrition (MN)]; (2) elevated C-reactive protein (CRP) ≥0.5 mg/dL (CRP-MN); and (3) presence of RA (RA-MN). In each of the three conditions, nutritional indicators between well-nourished and malnourished groups were compared by analysis of covariance. Factors associated with malnutrition were analyzed with logistic regression analysis. RESULTS The frequencies of malnutrition as defined by DAS-MN, CRP-MN, and RA-MN were 39%, 30%, and 71%, respectively. When malnutrition was defined by the DAS-MN and/or the CRP-MN, grip strength and serum ceruloplasmin, iron, and zinc levels showed significant differences between the well-nourished and malnourished groups (p < 0.05). The use of targeted synthetic or biological disease-modifying antirheumatic drugs (ts-/b-DMARD) (OR = 0.29; 95% CI 0.11-0.82), grip strength (OR = 0.83; 95% CI 0.75-0.91), subjective reduction in walking speed (OR = 5.24; 1.85-14.86) were significantly associated with malnutrition as determined by DAS-MN. CONCLUSION Differences in disease burden/inflammation affect nutritional assessments. The number of malnourished patients with RA was negatively associated with the use of ts-/b-DMARDs and high physical function in women.

Abstract
Background Diabetes has been proposed to inflict an insult on the hematopoietic milieu marked by changes in hematological indices including red blood cell parameters. Thus, this study aimed to assess the red blood cell parameters and their correlation with glycemic control in type 2 diabetic adult patients in comparison with apparently healthy individuals. Methods A comparative cross-sectional study was conducted at the chronic illness clinic of Hiwot Fana Comprehensive Specialized University Hospital from May 20 to July 10, 2022. A total of 220 (110 type 2 diabetic patients and 110 controls) study participants were selected by a simple random sampling technique. Five milliliters of venous blood were collected by the vacutainer blood collection technique. Red blood cell parameters and blood glucose levels were determined using UniCel DxH 800 and Biosystems A25 analyzers, respectively. Independent sample t-test and Pearson correlation test were used for the data analysis. P-value <0.05 was considered statistically significant. Results Statistically significant difference was observed in RBC parameters of T2DM patients and the control group. The mean RBC count, Hgb, Hct (P < 0.001), and MCHC (P = 0.002) in patients with type 2 diabetes was significantly lower than in the control group. However, the mean of RDW was significantly increased in type 2 diabetic patient groups than in the control group (P < 0.001). The mean RBC count, Hct, and Hgb in patients with good glycemic control were significantly higher than the patients with poor glycemic control. Besides, a statistically significant negative correlation was observed between glycemic control and RBC count, Hgb, and Hct level in diabetic patients. Conclusion In this study, a statistically significant difference was observed in red blood cell parameters of type 2 diabetic patients compared to the control group. A significant negative correlation was noted between glycemic control and RBC parameters in type 2 diabetic patients. Therefore, evaluation of RBC parameters should be considered for better management of patients with type 2 diabetes mellitus.

Abstract
Red blood cell distribution width (RDW) is a measure of the change in size of red blood cells and it is used in combination with other hematological parameters for the differential diagnosis of anemias. Recent evidence suggested that the change in RDW level may be a predictive biomarker of morbidity and mortality in cardiovascular diseases (CVDs). Cardiovascular diseases are the most common cause of death globally as compared to cancer and communicable diseases. Early diagnosis and prompt intervention of these diseases are very important to minimize their complications. Nowadays, the diagnosis of most cardiovascular diseases majorly depends on clinical judgment, electrocardiography and biochemical parameters. Red blood cell distribution width as a new predictive biomarker may play a pivotal role in assessing the severity and progression of CVDs. However, the underlying mechanisms for the association between RDW and CVDs are not clear. A deeper understanding of their association could help the physicians in more careful identification, early prevention, intervention, and treatment to prevent adverse cardiovascular events. This review aims to elaborate on the recent knowledge on the association between RDW and cardiovascular diseases and some possible pathophysiological mechanisms.

Abstract
The association between the red blood cell distribution width (RDW) and hemorrhagic transformation (HT) after thrombolysis in acute ischemic stroke patients remains inconclusive. Our study aimed to assess whether high RDW levels are associated with the occurrence of HT after thrombolysis. Data were consecutively collected and retrospectively analyzed for stroke patients treated with thrombolysis between 1 January 2017 and 31 December 2019. The primary outcomes were the occurrence of HT and symptomatic HT. Among the 286 patients enrolled, 36 (12.6%) developed HT and15 (5.2%) were classified as symptomatic HT. Patients with high RDW levels were associated with a higher percentage of HT and symptomatic HT (P<0.05). The RDW levels in the HT and symptomatic HT groups were also greater compared with the no-HT group (P<0.001). Multivariable logistic regression analysis revealed that high RDW levels were independently associated with an increased risk of HT (adjusted odds ratio 2.5, 95 % CI, 1.74–3.83 P < 0.001). In conclusion, we found that high RDW levels may be an independent predictor of HT in stroke patients after thrombolysis.

Abstract
BACKGROUND Although Kawasaki disease (KD) is known to cause anemia, the relationship between its prognosis and hemoglobin level is less well known. METHODS We herein performed a secondary analysis of data from a previous study (Post-RAISE). Children aged 6 months to 2 years at the time of KD diagnosis were enrolled. Decreased hemoglobin was defined as a decrease > 10% on post-treatment day 2 compared with the level prior to the initial therapy. RESULTS Of 1253 KD cases, treatment resistance was observed in 209 (17%) and was significantly more frequent in the decreased hemoglobin group (37/167 vs. 172/1086, P = 0.041). Multivariable logistic regression analysis revealed that decreased hemoglobin was associated with resistance to the initial treatment (odds ratio 1.53; 95% confidence interval 1.00-2.33; P = 0.048). CONCLUSIONS Decreased hemoglobin was significantly associated with resistance to initial treatment in patients with KD.

Abstract
BACKGROUND Micronutrients are minerals and vitamins and they are essential for normal physiological activities. The objectives of the study were to describe the progress and determinants of micronutrient levels and to assess the effects of micronutrients in the treatment outcome of kalazar. METHODS A prospective cohort study design was used. The data were collected using patient interviews, measuring anthropometric indicators, and collecting laboratory samples. The blood samples were collected at five different periods during the leishmaniasis treatments: before starting anti-leishmaniasis treatments, in the first week, in the second week, in the third week, and in the 4th week of anti-leishmaniasis treatments. Descriptive statistics were used to describe the profile of patients and to compare the treatment success rate. The generalized estimating equation was used to identify the determinants of serum micronutrients. RESULTS The mean age of the patients were 32.88 years [SD (standard deviation) ±15.95]. Male constitute 62.3% of the patients and problematic alcohol use was present in 11.5% of the patients. The serum zinc level of visceral leishmaniasis patients was affected by alcohol (B - 2.7 [95% CI: - 4.01 - -1.5]), DDS (B 9.75 [95% CI: 7.71-11.79]), family size (B -1.63 [95% CI: - 2.68 - -0.58]), HIV (B -2.95 [95% CI: - 4.97 - -0.92]), and sex (B - 1.28 [95% CI: - 2.5 - -0.07]). The serum iron level of visceral leishmaniasis patients was affected by alcohol (B 7.6 [95% CI: 5.86-9.35]), family size (B -5.14 [95% CI: - 7.01 - -3.28]), malaria (B -12.69 [95% CI: - 14.53 - -10.87]), Hookworm (- 4.48 [- 6.82 - -2.14]), chronic diseases (B -7.44 [95% CI: - 9.75 - -5.13]), and HIV (B -5.51 [95% CI: - 8.23 - -2.78]). The serum selenium level of visceral leishmaniasis patient was affected by HIV (B -18.1 [95% CI: - 20.63 - -15.58]) and family size (B -11.36 [95% CI: - 13.02 - -9.7]). The iodine level of visceral leishmaniasis patient was affected by HIV (B -38.02 [95% CI: - 41.98 - -34.06]), DDS (B 25 .84 [95% CI: 22.57-29.1]), smoking (B -12.34 [95% CI: - 15.98 - -8.7]), chronic illness (B -5.14 [95% CI: - 7.82 - -2.46]), and regular physical exercise (B 5.82 [95% CI: 0.39-11.26]). The serum vitamin D level of visceral leishmaniasis patient was affected by HIV (B -9.43 [95% CI: - 10.92 - -7.94]), DDS (B 16.24 [95% CI: 14.89-17.58]), malaria (B -0.61 [95% CI: - 3.37 - -3.37]), and family size (B -1.15 [95% CI: - 2.03 - -0.28]). The serum vitamin A level of visceral leishmaniasis patient was affected by residence (B 0.81 [95% CI: 0.08-1.54]), BMI (B 1.52 [95% CI: 0.42-2.6]), DDS (B 1.62 [95% CI: 0.36-2.88]), family size (B -5.03 [95% CI: - 5.83 - -4.22]), HIV (B -2.89 [95% CI: - 4.44 - -1.34]),MUAC (B 0.86 [95% CI: 0.52-1.21]), and age (B 0.09 [95% CI: 0.07-0.12]). CONCLUSION The micronutrient levels of visceral leishmaniasis patients were significantly lower. The anti-leishmaniasis treatment did not increase the serum micronutrient level of the patients.

Δ 9 -Tetrahydrocannabinolic acid alleviates collagen-induced arthritis: Role of PPARγ and CB 1 receptors. Br J Pharmacol 2020; 177:4034-4054. [PMID: 32510591 DOI: 10.1111/bph.15155] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 05/22/2020] [Accepted: 05/27/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND PURPOSE Δ9 -Tetrahydrocannabinolic acid (Δ9 -THCA-A), the precursor of Δ9 -THC, is a non-psychotropic phytocannabinoid that shows PPARγ agonist activity. Here, we investigated the ability of Δ9 -THCA-A to modulate the classic cannabinoid CB1 and CB2 receptors and evaluated its anti-arthritis activity in vitro and in vivo. EXPERIMENTAL APPROACH Cannabinoid receptors binding and intrinsic activity, as well as their downstream signalling, were analysed in vitro and in silico. The anti-arthritis properties of Δ9 -THCA-A were studied in human chondrocytes and in the murine model of collagen-induced arthritis (CIA). Plasma disease biomarkers were identified by LC-MS/MS based on proteomic and elisa assays. KEY RESULTS Functional and docking analyses showed that Δ9 -THCA-A can act as an orthosteric CB1 receptor agonist and also as a positive allosteric modulator in the presence of CP-55,940. Also, Δ9 -THCA-A seemed to be an inverse agonist for CB2 receptors. In vivo, Δ9 -THCA-A reduced arthritis in CIA mice, preventing the infiltration of inflammatory cells, synovium hyperplasia, and cartilage damage. Furthermore, Δ9 -THCA-A inhibited expression of inflammatory and catabolic genes on knee joints. The anti-arthritic effect of Δ9 -THCA-A was blocked by either SR141716 or T0070907. Analysis of plasma biomarkers, and determination of cytokines and anti-collagen antibodies confirmed that Δ9 -THCA-A mediated its activity mainly through PPARγ and CB1 receptor pathways. CONCLUSION AND IMPLICATIONS Δ9 -THCA-A modulates CB1 receptors through the orthosteric and allosteric binding sites. In addition, Δ9 -THCA-A exerts anti-arthritis activity through CB1 receptors and PPARγ pathways, highlighting its potential for the treatment of chronic inflammatory diseases such as rheumatoid arthritis.

Abstract
The achievement of virological response in the treatment of hepatitis C virus (HCV) can improve the extrahepatic manifestations. The present study aimed to investigate the effect of HCV eradication after sofosbuvir/daclatasvir (SOF/DCV) therapy on hematological and inflammatory biomarkers in type 2 diabetic patients infected with HCV genotype 4. Between October 2017 and August 2018, among 145 patients with HCV genotype 4, 30 patients were enrolled in the study based on the fact that they have type 2 diabetes. Enrolled HCV-diabetic patients were treated for 12 weeks with SOF/DCV regimen. Patients were screened by laboratory investigations before treatment (baseline values) and after HCV treatment (post-treatment values). Additionally, 30 healthy individuals were enrolled as a control group. Among the patient's cohort, the sustained virological response was achieved by 100% of the treated patients after 12 weeks of SOF/DCV therapy. Moreover, the levels of insulin resistance (HOMA-IR), nitric oxide, interleukin-1β, red cell distribution width, platelet distribution width, mean platelet volume were improved significantly (P < 0.001) in treated patients after successful viral clearance compared to baseline values. In addition, virological clearance exhibited positive correlations with interleukin-1β, nitric oxide, leukocytes count, red cell distribution width, and mean platelet volume. In conclusion, the data suggest the potential amelioration effect of HCV eradication after treatment with SOF/DCV regimen on the inflammatory status among HCV-diabetic patients which is reflected by the noticeable improvement of altered hematological indices and inflammatory biomarkers.

Abstract
BACKGROUND One common feature of chronic diseases, such as cancer, diabetes and chronic kidney disease (CKD), is the disruption of iron metabolism and increase in labile iron pool, which can result in excessive production of harmful oxidative stress. The proper management of iron metabolism in this situation can be a valuable tool to ameliorate pathological events. MATERIALS AND METHODS In the previous studies, the anti-neoplastic effects of BCc1, a nanochelating-based nanomedicine with iron-chelating property, were demonstrated in cell culture, animal models and clinical trials. In the present study, the therapeutic effects of BCc1 in animal model of diabetic kidney disease (DKD), induced by streptozotocin injection (35 mg/kg) and high-fat diet consumption, were evaluated. RESULTS The results showed that BCc1 significantly decreased HOMA-IR index, uric acid, blood urea nitrogen, malondialdehyde and 8-isoprostane. In addition, it reduced urinary albumin excretion rate and albumin-to-creatinine ratio in comparison to DKD control rats. This nanomedicine had no negative impact on liver iron content, hemoglobin level, red blood cell count, hematocrit and mean corpuscular volume, while it significantly decreased aspartate aminotransferase and alanine aminotransferase compared to DKD control group. Moreover, the histopathological assessment indicated that lesser glomerular basement membrane and wrinkling, mesangial matrix expansion and pathological changes in proximal cortical tubules were seen in the kidney samples of BCc1-treated rats. CONCLUSION In conclusion, BCc1 as an iron-chelating agent shows promising impacts in DKD animal model, which can ameliorate biochemical and pathological events of this disease.

Abstract
OBJECTIVE To evaluate the therapeutic effect of Qingshen Granules on renal anemia in patients with damp-heat syndrome and explore the mechanisms in light of inflammation/hepcidin axis and iron metabolism. METHODS Sixty patients with renal anemia and dampness-heat syndrome were randomized into control group (n=30) and treatment group (n=30). All the patients were given routine treatment, and the patients in the treatment group received additional treatment with Qingshen Granules (3 times a day). After 12 weeks of treatments, the patients were examined for changes in the integral value of TCM syndrome, serum creatinine (Scr), glomerular filtration rate (eGFR), hemoglobin (HGB), hematocrit (HCT), red blood cell (RBC) count, interleukin-6 (IL-6), hypersensitive C-reactive protein (hs-CRP), ferritin, growth differentiation factor-15 (GDF-15), serum iron (SI), total iron binding capacity (TIBC), transferrin saturation (TAST), soluble transferrin receptor (sTfR) and ferritin levels. RESULTS After the treatment, the scores of TCM syndrome were significantly improved in the treatment group and were better than those in the control group (P=0.000). Scr and eGFR were improved in both groups after the treatment. The levels of HGB, HCT and RBC were all improved in the two groups after treatment, and the improvements were more obvious in the treatment group (P=0.002, 0.002, and 0.017, respectively). The levels of IL-6, hs-CRP, hepcidine and GDF-15 were all lowered in the two groups after the treatment, and they were all significantly lower in the treatment group than in the control group (all P=0.000). The treatments increased the levels of SI and TAST in both of the groups, and compared with those in control group, the levels of TIBC, sTfR and ferritin were significantly lowered in the treatment group after the 12-week treatment (P=0.000). CONCLUSIONS Qingshen granules can effectively improve renal anemia in patients with damp-heat syndrome possibly by improving iron metabolism through alleviation of inflammation and reduction of hepcidine level.

Abstract
BACKGROUND Most guidelines all over the world recommended metformin as the first-line treatment for in type 2 diabetic patients. Therefore, the present study was suggested to assess the outcome of metformin administration and glycemic status on alterations in red blood cell (RBCs) indices as well as the oxidative stress in type 2 diabetic patients. METHODS Between December 2016 and October of 2017, a total of 158 eligible individuals were classified as 50 healthy subjects and 108 diabetic patients who were subdivided into six groups according to the type of anti-diabetic treatments. RESULTS Overall, the results elucidated that hemoglobin concentration was markedly diminished, while red cell distribution width (RDW) value was significantly (P < 0.001) elevated in all diabetic groups as compared to control. Moreover, in all diabetic groups, malondialdehyde (MDA) concentration was elevated noticeably (P < 0.001), while reduced glutathione (GSH) revealed a lower concentration (P < 0.001) than that of control. CONCLUSION The present study exhibited the amelioration effect of metformin administration on oxidative stress and glycemic status which reflected on some RBCs indices. However, hemoglobin concentration showed a noticeable diminution in all metformin-treated groups in spite of the improvement in glycemic and oxidative stress status which indicated that the metformin-induced anemia is independently from diabetic complications.

Abstract
BACKGROUND Helicobacter pylori infection is associated with iron deficiency (ID) in children. Inflammatory cytokine reactions could influence the consequences of H. pylori infection. Hepcidin is an important regulator in iron homeostasis and could be induced by chronic inflammation. The relationship between hepcidin and cytokine levels in children infected with H. pylori remains controversial. METHODS Based on serology testing for anti-H. pylori IgG, participants (43 seropositive and 43 seronegative) aged 10-18 years were enrolled. Serum hepcidin levels and iron profiles, including iron, ferritin, and total iron-binding capacity, were measured. ID is defined as iron saturation less than 15%. Seropositive children were divided into low hepcidin (n = 22) and high hepcidin (n = 21) groups. IL-1β, IL-6, and IL-8 serum levels were compared. RESULTS Serum IL-1β and IL-6 levels were comparable between H. pylori seropositive and seronegative children, as were the median serum hepcidin levels (6.5 ng/mL versus 8.6 ng/mL; P = 0.1318). Median levels of serum iron, ferritin, and iron saturation were significantly lower in seropositive children with low hepcidin than in those with high hepcidin (P = 0.0123, P = 0.0001, and P = 0.0004, respectively). The prevalence of ID was significantly higher in those with low serum hepcidin levels (33.3% versus 4.5%; P = 0.015). Compared to the high hepcidin seropositive group, the low hepcidin group had significantly lower median serum levels of cytokines IL-1β and IL-6, but not IL-8 (P = 0.0151 and P = 0.0015, respectively). CONCLUSIONS Inflammatory cytokines IL-1β and IL-6, but not IL-8, might be associated with increased hepcidin levels among H. pylori-seropositive children. Further studies are needed to clarify the role of hepcidin.

Abstract
The red blood cell distribution width (RDW) obtained from a standard complete blood count (CBC) is a convenient and inexpensive biochemical parameter representing the variability in size of circulating erythrocytes. Over the past few decades, RDW with mean corpuscular volume (MCV) has been used to identify quite a few hematological system diseases including iron-deficiency anemia and bone marrow dysfunction. In recent years, many clinical studies have proved that the alterations of RDW levels may be associated with the incidence and prognosis in many cardiovascular and cerebrovascular diseases (CVDs). Therefore, early detection and intervention in time of these vascular diseases is critical for delaying their progression. RDW as a new predictive marker and an independent risk factor plays a significant role in assessing the severity and progression of CVDs. However, the mechanisms of the association between RDW and the prognosis of CVDs remain unclear. In this review, we will provide an overview of the representative literatures concerning hypothetical and potential epidemiological associations between RDW and CVDs and discuss the underlying mechanisms.

Semin Arthritis Rheum 2017; 47:193-198. [PMID: 28385457 DOI: 10.1016/j.semarthrit.2017.03.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 03/05/2017] [Accepted: 03/07/2017] [Indexed: 01/06/2023]
Abstract
OBJECTIVE Anemia is a common problem in rheumatoid arthritis (RA), associated with radiographic progression and disability. We explored the association of hemoglobin with a comprehensive set of variables in RA patients. METHODS We included RA outpatients in the routine setting. For each patient we performed measurements (clinical measures, blood tests including serology, markers of acute phase response and iron metabolism, including hepcidin, and circulating hematopoietic precursor levels) at baseline and 12 weeks thereafter, and analyzed their changes in patients with a treatment adaptation at baseline. We performed principal component analysis (PCA) to identify thematic groups hemoglobin was related to. Then we constructed multivariable linear models to assess the contribution of individual variables to the variability of hemoglobin. RESULTS In total, 88 patients were included (age: 58 ± 12; disease duration: 9.3 ± 9.6 years). Cross-sectionally (at baseline and week 12) hemoglobin levels were tied to iron metabolism and hematopoiesis, but not to clinical activity, based on thematic groups extracted from the PCA. In contrast, longitudinal changes in hemoglobin levels were closely linked to changes in clinical activity. Conversely, hepcidin reflected iron metabolism cross-sectionally, but changes in acute phase response longitudinally. In multivariable analysis variability components of hemoglobin were explainable by ferritin, ESR, evaluator global assessment (EGA), and iron levels, while components of hemoglobin changes were explained by changes in EGA mostly. Hepcidin was not independently associated with hemoglobin. CONCLUSION Besides its dependence on body iron status, changes in hemoglobin levels are strongly tied to disease activity, possibly revealing more about disease activity than other laboratory markers.
