Hematological Indices in Patients With Goiter: A Cross-Sectional Study in a Tertiary Care Hospital in South India.

Abstract

Introduction A wide range of haematological abnormalities have been observed in patients with goitre. The aim of the study was to evaluate the abnormalities in haematological parameters among patients with goitre in a tertiary care hospital in south India. Methods This was a cross-sectional study carried out in the pathology department of Chengalpattu Medical College from April 1 to June 30, 2019. The lab reports, including the complete blood count (CBC) and serum thyroid profile that included thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) of all the patients with goitre, were retrieved from the laboratory records. Results were tabulated and analysed. Results Out of a total of 200 patients with thyroid dysfunction, 12 (6%) were males and 188 (94%) were females, with the majority (51.5%) of them in the age group of 30-60 years. Serum TSH levels showed a statistically significant association with red cell distribution width (RCDW) (P-value = 0.000), mean corpuscular volume (MCV) (P-value = 0.020), and total white blood cell (WBC) count (P-value = 0.003) among the patients with goiter. There was no significant association between TSH and other parameters like haemoglobin, packed cell volume (PCV), red blood cell (RBC) count, and platelet (PLT) count. Conclusions Red cell distribution width and mean corpuscular volume are useful haematological parameters that will help clinicians in the early diagnosis and proper treatment of haematological abnormalities seen in patients with goitre.
