ABSTRACT
@#Introduction: Anemia and thyroid conditions effect each other in clinical practice. Anemia may induce alteration in thyroid hormone status and various thyroid conditions induce various types of anemia. In present study, we aimed to study the thyroid function tests of the anemic subjects and to compare characteristics and laboratory features of the three groups; hypothyroid, hyperthyroid, and euthyroid subjects. Methods: Anemic subjects divided into three groups according to the thyroid hormone status, either as hyperthyroid, hypothyroid and euthyroid groups. Hemogram indices and laboratory parameters compared between three groups. Results: Mean red cell distribution width (RDW) of hypothyroid anemic subjects was significantly lower than the RDW of euthyroid anemic subjects (p=0.003). White blood cell (WBC) count of hypothyroid anemic subjects was significantly reduced compared to the euthyroid (p<0.001) and hyperthyroid (p=0.047) anemic subjects. Significant inverse correlation between RDW and TSH (r=-0.25, p=0.001), between RDW and hemoglobin (r=-0.44, p<0.001), between RDW and hematocrit (r=-0.35, p<0.001) and between RDW and mean corpuscular volume (r=-0.53, p<0.001) were noted. Conclusions: Since anemia is common in thyroid conditions, besides its role in differential diagnosis of the anemia, RDW could also serve as an adjunct diagnostic tool in estimation of the thyroid hormone status in anemic subjects.
ABSTRACT
BACKGROUND AND PURPOSE: Lumbar disc herniation (LDH) causes major disabilities worldwide. Several studies in the literature had reported the correlation between radiculopathy and inflammatory markers. Mean platelet volume (MPV), red cell distribution width (RDW) and neutrophil to lymphocyte (N/L) ratio are parameters of hemogram which have been found to be associated with inflammatory conditions. Purpose - Since inflammation has an important role in lumbar disc hernias, and RDW, MPV and N/L ratio are also known to be in correlation with inflammation, we have investigated these parameters of the patients with lumbar disc hernias and compared them with the results of the healthy subjects. METHODS: Our study group was composed of patients with lumbar disc hernia, whereas the control group was consisted of healthy volunteers whom visited our outpatient clinics for a routine check-up. Patient characteristics and hemogram parameters of the study cohort were obtained from computerized database system of our institution. SPSS software (SPSS 15.0 for Windows, Chicago, IL, USA) was used for the analysis. RESULTS: There was no significant difference between study and control groups in terms of WBC, neutrophil count, lymphocyte count, neu\lym ratio, Hb, Htc, MCV, and PLT levels (all p>0.05). RDW was significantly increased in study group [15.6 (12.3-22.5)] when compared to control group [14.5(11.9-16.3)] (p=0.004). And MPV in the study group [9.25 (6.38-14.5)] was also significantly increased in comparison to the control subjects [8.8 (6-10.1)] (p=0.013). CONCLUSION: In this retrospective study, we found that, RDW and MPV values in hemograms were increased in patients with lumbar disc herniation when compared to the control group. Conclusions - We suggest that, elevated RDW and MPV may help physicians in decision taking to order radiological imagings in patients with symptoms which can be associated with possible LDH diagnosis. However, for the sake of precision, prospective studies with larger populations are needed.
