Thyroid disorders in chronic hepatitis C virus infection

TLDR
A significant increase of the prevalence has been observed both for thyroid autoimmune disorders as well as for hypothyroidism, and the abovementioned evidences seem sufficient to suggest careful thyroid monitoring during the follow-up of patients with HCV infection.
Abstract
The prevalence of thyroid disorders has been evaluated in patients with hepatitis C virus (HCV) infection by many studies. From a review of the published controlled studies, it is possible to observe that: (1) most investigated patients with chronic HCV hepatitis, while a minority evaluated hepatitis C virus antibody (HCVAb)- seropositive patients (the two conditions are not comparable with regards to thyroidal repercussions, in fact, HCVAb-seropositive patients do not necessarily display changes of the immune system present in chronically infected HCV patients); and (2) some authors selected as internal control hepatitis B virus (HBV)-infected patients, while others selected apparently healthy controls or HCVAb-negative subjects. Pooling all data about HCV-positive patients (with chronic hepatitis or HCVAb positivity) and using as control the sum of healthy controls, HBV-infected patients and sera negative for HCVAb, a significant increase of the prevalence has been observed both for thyroid autoimmune d...

TL;DR: E Epidemiological data suggest that AITD patients should be accurately monitored for thyroid dysfunctions, the appearance of thyroid nodules, and other autoimmune disorders.

Viruses and thyroiditis: an update

TL;DR: This review examines the data related to the role of viruses in the development of thyroiditis at different levels of evidence; epidemiological data, serological data or research on circulating viruses, direct evidence of thyroid tissue infection.

TL;DR: Recent data on the genetic predisposition to AITD lead to novel putative mechanisms by which the genetic-environmental interactions may lead to the development of thyroid autoimmunity.

Endocrine and liver interaction: the role of endocrine pathways in NASH

TL;DR: Clinicians should be aware of the potential role of endocrine disorders in patients with cryptogenic liver disease and of the effects of liver function on the endocrine system, as evidence that causally links hormonal disorders with hepatobiliary disease is reviewed.

Isolation of a cDNA clone derived from a blood-borne non-A, non-B viral hepatitis genome

TL;DR: A random-primed complementary DNA library was constructed from plasma containing the uncharacterized non-A, non-B hepatitis agent and screened with serum from a patient diagnosed with NANBH, showing consistent with the agent being similar to the togaviridae or flaviviridae.

The Prevalence of Hepatitis C Virus Infection in the United States, 1988 through 1994

TL;DR: The strongest factors independently associated with HCV infection were illegal drug use and high-risk sexual behavior, and poverty, having had 12 or fewer years of education, and having been divorced or separated were independently associated.

Prevalence of Type 2 Diabetes Mellitus among Persons with Hepatitis C Virus Infection in the United States

TL;DR: The hypothesis that persons with HCV infection have an increased prevalence of type 2 diabetes after adjustment for important confounding variables, including age, body mass index, poverty level, and history of drug and alcohol use is tested.
