Hypothesis
The study investigates the changes in titer and isotype analysis of antimitochondrial antibodies in patients with primary biliary cirrhosis over a long follow-up period.
Conclusion
The study found that the titer of antimitochondrial antibodies did not significantly change over time, and higher titers were observed in younger patients.
Supporting Evidence
- The titer of antimitochondrial antibodies was significantly higher in younger patients.
- No significant change in antibody levels was noted during the long follow-up period.
- The study analyzed sera from patients followed for a mean duration of 13.5 years.
Takeaway
Doctors looked at blood samples from patients with a liver disease called primary biliary cirrhosis over many years and found that certain antibodies didn't change much, especially in younger patients.
Methodology
The study used immunoblot and enzyme-linked immunosorbent assays to analyze stored sera from patients followed for 7-28 years.
Limitations
The study may not be entirely representative of the spectrum of disease observed in primary biliary cirrhosis.
Participant Demographics
Nineteen of the twenty patients were women, aged 25 to 73 years at initial evaluation.
