Background: Overt and subclinical hypothyroidism, affects metabolism of lipids particularly that of cholesterol, low density lipoprotein and triglyceride. Hypercholesterolemia predisposes to atherosclerosis and thereby increases cardiovascular risks.Methods: Hundred patients of primary hypothyroidism of age more than 15 yrs were included. Five milliliters of venous blood was drawn in fasting state and serum obtained; thyroid function test (TFT) and fasting lipid profile were performed. Based on the TFT, patients were categorized as sub clinical or overt hypothyroidism. Clinical data, thyroid and lipid profiles obtained were analyzed and compared using statistical methods.Results: Seventy patients were females and thirty were males in the ratio of 2.3:1. Most common age group was 51-60years followed by 41-50years. Most common symptom was generalised weakness followed by weight gain, cold intolerance, constipation, hair loss, paraesthesia’s. Most common signs were myxoedema, delayed ankle reflex relaxation, dry and coarse skin, bradycardia, non-pitting peripheral edema, madarosis, pallor, goiter. Patients with Overt hypothyroidism had significantly higher serum levels of total cholesterol(249.1±31.7 mg/dl), Triglycerides (191.5±68.5 mg/dl) and LDL cholesterol(167.7±31 mg/dl) than the Subclinical hypothyroidism with total cholesterol(202±19.8),triglycerides(155.6±35) and LDL cholesterol(129±21.1) but HDL cholesterol level remains normal in both overt (44.0±4.7) and subclinical (43.1±4.4)hypothyroidism respectively.Conclusions: Patients with Overt hypothyroidism had significantly higher levels of Total cholesterol, Triglycerides (TG) and LDL cholesterol than the Subclinical hypothyroidism but HDL cholesterol level remains normal in both. So, concomitant estimation of lipid profile in hypothyroidism patients is needed for early intervention and prevention of cardiovascular morbidity and mortality.
Background & objectives: Hydroxyurea (HU) has been useful in preventing sickle cell vaso-occlusive crises (VOC). A few studies also suggest utility of HU, during acute VOC. Sickle cell anaemia (SCA) is of high prevalence in western districts of Odisha State, India, and VOC is a common presentation, despite being mostly of Arab-Indian haplotype. This study was undertaken to evaluate the impact of HU on hospital stay and analgesic utilization in acute painful VOC of SCA. Methods: Homozygous sickle cell disease (HbSS) patients were categorized as cases who were receiving low-dose HU (10 mg/kg/day) and patients who were not on HU were considered as control. Days of hospital stay, analgesic utilization and visual analogue scale (VAS) score in patients were compared with that of control. Analgesics used to control pain were tramadol hydrochloride, ketorolac and diclofenac. Results: A total of 359 homozygous sickle cell disease (SCD) patients with VOC were studied (187 patients and 172 controls). The patient group had lesser mean days of hospital stay (1.4 days less than controls, P <0.001) and required lesser days of analgesic utilization than controls (1.18 days less than controls, P <0.001). Significant differences were observed between patients and controls concerning VAS score and amount of tramadol hydrochloride, ketorolac and diclofenac utilization ( P <0.05). Interpretation & conclusions: In this study, HU was found to have beneficial effects in acute VOC of homozygous SCD, which includes shortening the duration of hospital stay and reducing the net amount of analgesic utilization during hospitalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
