Introduction: Red blood cell distribution width (RDW) has been considered as an inflammatory marker in various disorders. Evaluation of RDW value can also be used as a novel and additional marker for differentiating systemic vasculitis from primary cutaneous vasculitis. Objective: To compare RDW value between patients with cutaneous vasculitis with systemic vasculitis, thereafter to find out it's role as an effective indicator to distinguish both forms of vasculitis. Materials and Methods: This cross sectional observational study was conduct between from July 2016 to December 2017. Total of 48 patients were divided into primary cutaneous vasculitis and systemic vasculitis. Blood was collected in EDTA tube to measure RDW value. Patient’s disease activity also scored and plotted according to Birmingham vasculitis activity score. Statistical analysis was performed by using SPSS. Results: Significantly high mean RDW were found in patients with systemic vasculitis compared to primary cutaneous vasculitis (15.09±0.92 vs. 13.48±1.1, p = 0.000). BVAS was significantly greater (13.93±5.10 vs. 4.87±2.69, p = < 0.001) in systemic vasculitis as well as in patients with high RDW group (11.73±5.71 vs. 5.37±3.96, p = < 0.001). Optimal RDW cut off point for differentiating systemic vasculitis from cutaneous vasculitis was 14.2 with 81.3% sensitivity and 81.2% specificity.  Conclusion: Present study revealed importance of RDW monitoring along with disease activity in patients with any form of vasculitis. Systemic vasculitis had higher level of RDW. So RDW can be considered as a marker to discriminate systemic vasculitis from primary cutaneous vasculitis. Medicine Today 2021 Vol.33(2): 84-89

 Stroke is a functional disorder attributed to acute focal or global brain injury by vascular cause and persists more than 24 hours. Stroke is divided into ischemic and hemorrhagic strokes. Red Blood Cell Distribution Width (RDW) is a measurement of erythrocyte volume variation in blood circulation. Increased RDW reflects the inflammation that plays a role in the development of atherosclerosis in stroke. This study aims to analyze differences in RDW-CV values in patients with stroke. The design was cross-sectional with a retrospective approach, secondary data from medical records of inpatients with stroke from January to December 2016 at the Dr. Wahidin Sudirohusodo Hospital. The study population consisted of 490 patients aged ≥ 18 years old. The Kruskal-Wallis, Mann-Whitney, and Anova one way tests were used to analyze differences in RDW-CV values in patients with ischemic and hemorrhagic stroke. Mann-Whitney test results showed no significant difference in RDW-CV values between groups of ischemic and hemorrhagic stroke (p 0.96). Kruskal-Wallis and Anova one way tests showed no significant difference in RDW-CV values between four groups of patient outcomes in ischemic and hemorrhagic stroke (p 0.13 and p 0.35 consecutively). There were no significant RDW-CV values between ischemic and hemorrhagic stroke. There was no significant difference between RDW-CV values of four groups of patient outcomes in ischemic and hemorrhagic stroke. RDW-CV values cannot be used to distinguish both ischemic and hemorrhagic stroke, including the prediction of stroke mortality

AbstractIntroduction: Present study was performed to verify red blood cell distribution width-to-platelet ratio (RPR) level in rheumatoid arthritis (RA) patients and to examine its correlation with clinical and biochemical indicators of disease activity status.Methods: In this cross-sectional analytical study, 67 patients with RA and 34 age- and gender-matched healthy control subjects were enrolled. Based on the disease activity score 28-ESR (DAS28-ESR), RA patients were divided into subgroups: low disease activity (n=20), moderate disease activity (n=22) and high disease activity (n=25). Laboratory tests included erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, platelet count (PLT), red blood cells count (RBC), red blood cells distribution width (RDW) and fibrinogen concentration. Statistical analyses were carried out using SPSS 13 software. Statistical significance was set at a p-value less than 0.05.Results: There was statistically significant difference (p=0.006) between RPR in RA patients with different stages of disease activity, with higher values in patients with low disease activity. The RPR showed statistically significant negative correlations with ESR (rho= -0.309; p=0.012), CRP (rho= -0.421; p=0.001), swollen joint count - SJC (rho = -0.368; p=0.002) and tender joint count - TJC (rho= -0.355; p=0.003), DAS28-ESR (rho= -0.409; p=0.001), DAS28-CRP (rho= -0.422; p<0.0005) and Visual analogue scale - VAS (rho= -0.260; p=0.033) in RA patients.Conclusion: The present study provided evidence that the lower RPR values in RA patients are significantly associated with the disease activity indicators.
