Higher values of TFQI are associated with
obesity,
metabolic syndrome, impaired
renal function,
diabetes, and diabetes-related
mortality. In a large population of community-dwelling euthyroid subjects the thyroid feedback quantile-based index predicted all-cause mortality, even after adjustment for other established risk factors and comorbidities. A cross-sectional study from Spain observed increased prevalence of type 2 diabetes, atrial fibrillation, ischemic heart disease and hypertension in persons with elevated PTFQI. Serum Concentrations of Adipocyte Fatty Acid-Binding Protein (A-FABP) are significantly correlateted to TFQI, suggesting some form of cross-talk between adipose tissue and HPT axis. TFQI results are also elevated in
takotsubo syndrome, potentially reflecting type 2
allostatic load in the situation of
psychosocial stress. Reductions have been observed in subjects with
schizophrenia after initiation of therapy with
oxcarbazepine and quetiapine, potentially reflecting declining allostatic load. Despite positive association to metabolic syndrome and type 2 allostatic load a large population-based study failed to identify an association to risks of
dyslipidemia and
non-alcoholic fatty liver disease (NAFLD). == See also ==
