The Liver in the World Trade Center Health Program General Responder Cohort and Controls
Studieoversikt
Status
Intervensjon / Behandling
Detaljert beskrivelse
This is a prospective cross-sectional study of liver disease in individuals who meet the United States Preventive Services Task Forces guidelines for lung cancer screening because they are between 55 and 80 years of age and have a 30 year pack-history of smoking and are either current smokers or who quit during the past 15 years. Liver disease will be compared between individuals who are members of the World Trade Center General Responder Cohort and individuals who are not members of this cohort. The basic objective is to determine whether exposure to the WTC attack increased liver disease.
Data will be obtained from the World Trade Center Data Center, from Mount Sinai Medical records, EPIC, the data warehouse, and from data collected by the Lung Cancer Screening Program of Dr. Henschke. Results of genetic tests that relate to liver disease will be collected from the medical record.

FibroScan- Controlled Attenuation Parameter (CAP) scores
Tidsramme: Day 1

assesses liver fat using a patented technique called Vibration-Controlled Transient Elastography range from 0 -400 CAP with the higher number indicating great quantity of fat in the Liver CAP 240-270 S1 Mild Steatosis CAP 270-300 S2 Moderate Steatosis CAP >300 S3 Severe Steatosis

Fibroscan
Tidsramme: Day 1
|
assesses liver stiffness using a patented technique called Vibration-Controlled Transient Elastography. Results are measured using kiloPascal's (or kPa) and range from 2 to 75kPa, with a higher number indicating more liver scarring. F0 Zero 5.3 kPa means no scarring F1 5.3-7.0 kPa is mild fibrosis F2 is 7.1-8.0 kPa moderate fibrosis F3 8.1-12.4 kPa is severe fibrosis F4 greater than 12.5 kPa is cirrhosis or advanced fibrosis, |

Composite score for Fibrosis and Steatosis
Tidsramme: Day 1

Composite score from Fibroscan to compare for exposure to WTC site Clinically significant fibrosis will be defined as Fibroscan >8.0kPa and Steatosis will be defined as a Fibroscan CAP >300dB/m indicating advance steatosis <7.9 kPa score Zero , >8.0 kPa score 1, <299 CAP will score Zero, >300 CAP will score 1 Range of total score Zero -2 equals best to worst scoring
