A excessive parathyroid hormone (PTH) degree was considerably related to nonalcoholic fatty liver illness (NAFLD) and nonsignificantly related to nonalcoholic steatohepatitis (NASH) in a meta-analysis.


  • The researchers carried out a scientific evaluation and meta-analysis of 12 case-control research of sufferers with NAFLD/NASH and a comparability group with out NAFLD/NASH.

  • All research had information on imply PTH ranges in instances and controls.

  • Pooled weighted imply distinction (WMD) was calculated by combining WMDs of every examine utilizing a random-effects mannequin.


  • A meta-analysis of 10 research with 1051 sufferers with NAFLD and 1510 controls revealed a big affiliation between excessive PTH degree and NAFLD, with a pooled WMD of 5.479.

  • A meta-analysis of 4 research with 99 sufferers with NASH and 143 controls revealed a development towards an affiliation of excessive PTH degree and NASH, with a pooled WMD of 11.995; statistical significance was not achieved owing to insufficient energy.

  • Each meta-analyses had excessive statistical heterogeneity (I 2 of 82.4% for NAFLD and 81.0% for NASH).


“These findings could have scientific implications as they could counsel that prime PTH degree could possibly be one other biochemical marker of presence of NAFLD and probably NASH,” the researchers wrote.


This examine was led by Aunchalee Jaroenlapnopparat, MD, Mount Auburn Hospital/Beth Israel Lahey Well being, Cambridge, Massachusetts. It was published online July 7 in Diabetes & Metabolic Syndrome: Analysis & Evaluations. The examine had no funding.


This systematic evaluation and meta-analysis included observational research, which could not present a causal relationship owing to potential confounding results. Each meta-analyses demonstrated excessive statistical heterogeneity, in all probability as a result of variations in examine design, inhabitants, and high quality among the many included research. The variety of research and individuals within the NASH-related evaluation had been restricted, which can have compromised the statistical energy of the evaluation.
