Objective: To investigate hematologic variables related to iron deficiency and food intake in attention-deficit/hyperactivity disorder. Method: The sample comprised 62 children and adolescents (6-15 years old) divided into three groups: Group 1: 19 (30.6%) patients with attention-deficit/hyperactivity disorder using methylphenidate for 3 months; Group 2: 22 (35.5%) patients with attention-deficit/hyperactivity disorder who were methylphenidate naïve and Group 3: 21 (33.9%) patients without attention-deficit/hyperactivity disorder. Serum iron, ferritin, transferrin, hemoglobin, mean corpuscular volume, red cell distribution width, mean corpuscular hemoglobin concentration, nutritional diagnostic parameters - Body Mass Index Coefficient, food surveys were evaluated among the groups. Results: The attention-deficit/hyperactivity disorder group drug naïve for methylphenidate presented the highest red cell distribution width among the three groups (p = 0.03). For all other hematologic and food survey variables, no significant differences were found among the groups. No significant correlation between dimensional measures of attention-deficit/hyperactivity disorder symptoms and ferritin levels was found in any of the three groups. Conclusion: Peripheral markers of iron status and food intake of iron do not seem to be modified in children with attention-deficit/hyperactivity disorder, but further studies assessing brain iron levels are needed to fully understand the role of iron in attention-deficit/hyperactivity disorder pathophysiology.

Iron deficiency anemia is common problem during pregnancy. Red cell size variation (anisocytosis) is the earliest morphologic changes in iron deficiency anemia. Red cell distribution width is a quantitative measure of red cell size variation and it can give the idea of early iron deficiency before other test to become positive.190 pregnant women were included in this study. Red cell distribution width was compared between iron deficient & non-iron deficient pregnant women. Red cell distribution width also compared with Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film in prelatent iron deficiency, latent iron deficiency, mild and moderate iron deficiency anemia. Red cell distribution width had sensitivity 82.3% and specificity 97.4%. Whereas Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film all had 56.6%, 29.2%, 68.1%, 15% and 38.9% sensitivity but specificity was 90.9%, 98.7%, 83.1%, 96.1% and 98.7% in the detection of iron deficiency. Red cell distribution width appears to be a reliable and useful parameter for detection of iron deficiency during pregnancy.

Abstract Background: Type 2 Diabetes Mellitus (T2 DM) is a common type of DM characterized by hyperglycemia. Glycation of hemoglobin and related proteins in DM can affect the physiological and structural properties of red blood cells. Although glycated hemoglobin (HbA1c) test continues to be the gold standard for the assessment of long-term glycemic control accessibility and affordability of the test in routine diagnosing service are still limited in developing countries. Hence, this study was aimed to assess red blood cell parameters as a biomarker for long-term glycemic monitoring among T2 DM patients.Methods: Facility-based cross-sectional study through a consecutive sampling technique was conducted among 124 T2 DM patients at the chronic illness follow-up clinic of Jimma Medical Center (JMC) from July 27 to August 31, 2020. A structured questionnaire was used to collect socio-demographic and clinical-related data. Five milliliters of the blood specimen was collected from each eligible T2 DM patient. HbA1c and red blood cell parameters were determined by Cobas 6000 and DxH 800 fully automated analyzers respectively. Data were entered into Epi-data software version 3.1 and exported to SPSS 25 version for analysis. Independent t-test and Pearson’s correlation coefficient were used to address the research questions. A P-value < 0.05 was considered statistically significant. Results: The mean age of study participants was 51.84± 11.6 years. 60.5% of T2 DM patients were in poor glycemic control. There was a significant mean difference between good and poor glycemic controlled T2 DM patients in red blood cell count (4.79±0.5 vs 4.38±0.8), hemoglobin (14.13±1.4 vs 13.60±1.6), mean corpuscular volume (89.52±4.7 vs 92.62±7.5), mean corpuscular hemoglobin (29.63±1.6 vs 30.77±2.9), and red cell distribution width (13.68±1.1 vs 14.63±1.2) respectively. Red blood cell count was inversely correlated (r=-0.280, p=0.002) with HbA1c while mean corpuscular volume (r=0.267, p=0.003), mean corpuscular hemoglobin (r=0.231, p=0.010), and red cell distribution width (r= 0.496, p=0.000) were positively correlated with level of HbA1c. Conclusion: Red cell count, mean corpuscular volume, mean corpuscular hemoglobin, and red cell distribution width could be useful indicators to monitor the glycemic status of T2 DM patients instead of HbA1c, though large prospective studies should be considered.

Abstract Introduction Oral submucous fibrosis (OSMF) is associated with nutritional deficiencies—primarily of iron and vitamins and usually seem to be associated with anemia. Red cell distribution width (RDW) is one of the routinely assessed parameters in complete blood picture analysis of any patient. It measures range of variation in erythrocyte size. A high RDW value has been associated to adverse outcomes in several diseases and risk of death. However, the relationship of RDW and OSMF is yet to be established. Aim To analyze the association of RDW levels and other erythrocytic indices with clinical staging and prognosis of OSMF patients. Materials and Methods Analysis of clinical stage and hematologic status of 86 patients comprising the study group (OSMF cases and OSMF with malignant changes) and control group was performed. It was done using Kruskal–Wallis analysis of variance test. Results The values of mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were below normal from the onset of oral submucous fibrosis and they continued to decrease as the disease progressed. On other hand, RDW values were found to be in normal range in initial stages of disease and they became high in stage IV OSMF and increased further in OSMF patients with malignant changes. Conclusion We observed that higher values of RDW are strongly and independently associated with OSMF and OSCC, suggesting that RDW may contribute as most economic novel biochemical marker for progression and malignant transformation of OSMF.

Abstract Objective: To explore the value of mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW) for overall survival (OS) and progression-free survival (PFS) in patients with pancreatic cancer (PC) who underwent radical pancreatomy.Background: Inflammatory factors are important factors in promoting the occurrence and metastasis of malignant tumors. RDW and MCHC are suggested to be relevant to the prognosis of several malignancies. Such as gastric cancer, colon cancer. However, there are few studies to explore the correlation between them and PC.Methods: This study included 532 patients with PC who underwent radical resection between March 2011 and May 2019. Kaplan-Meier curve method and Cox proportional hazard regression model were applied to analyze prognosis. Correlations between categorical variables were analyzed using Chi squared tests.Results: Survival curve showed that OS and PFS were significantly favorable for resectable PC patients with high preoperative MCHC (P=0.02) (P=0.005), RDW in the normal range (P<0.001) (P<0.001). Multivariate analysis suggested that MCHC (HR: 0.612, 95%CI: 0.426-0.879, P=0.008), and RDW (HR: 3.969, 95%CI: 2.952-5.338, P<0.001) were independent prognostic factors for resectable PC patients. MCHC (HR: 0.657, 95%CI: 0.458-0.943, P=0.023), RDW (HR: 3.915, 95%CI: 2.923-5.243, P < 0.001) were also independent recurrent factors for resectable PC patients. Correlation analysis showed that MCHC was related to tumor size, nerve invasion, and anemia-related indicators, meanwhile RDW was connected with carcinoma-embryonic antigen (CEA) and carbohydrate antigen199 (CA19-9).Conclusion: The preoperative MCHC and RDW were simple and convenient predictive factors for prognosis and progression of patients with PC.
