A 32-year-old female, known case of hypothyroidism since 3 years & since 2 months developed an influenza-like syndrome. Polymerase chain reaction assay confirmed the diagnosis of H1N1 virus infection. Serum thyroid stimulating hormone was suppressed to zero while the levels of thyroxine (T4) and...
Hormones T3, T4, TSH and prolactin levels were estimated by enzyme linked fluorescent immunoassay (ELFA) method in all the study subjects.Results: In the present study there was a positive correlation of hyperprolctinemia with hypothyroidism in both primary and secondary infertile women.Conclusions: ...
Secondary hypothyroidism is a condition in which a person's hypothalamus or pituitary gland doesn't work properly, causing weight...

Background: Elevated free thyroxine could be primary or secondary, endogenous or exogenous and often presents with symptoms of hyperthyroidism. Thyroxine levels are low in hypothyroidism, where the individual requires exogenous supplementation to maintain a euthyroid state. However, thyroxine levels may be...
ACTH group obtained significant elevated level of corticosterone (p < 0.05) and low levels of HT (p < 0.0001). Despite, TSH levels showed no significant difference between groups, ie, compatible with hypothyroidism secondary to hypercortisolism. Additionally, D2 levels showed no significant ...
Primary hypothyroidism is defined as a deficiency of thyroid hormone owing to intrinsic failure of the thyroid gland. This leads to low levels of circulating thyroxine, insufficient levels of thyroid hormone in target tissues, and typical symptoms, signs, and laboratory abnormalities. When severe or ...
No significant change in free T3 and free T4 was observed throughout the study in any group. Conclusion: In obese PCOS patients with primary hypothyroidism, metformin results in a significant fall and sometimes normalisation of TSH, without causing any reciprocal changes in other thyroid function ...
