Summary
Lactate dehydrogenase isoenzyme analysis in auricular pseudocyst fluid reveals distinct patterns. Higher levels of LDH 4 and 5, and lower levels of LDH 1 and 2, aid in diagnosing auricular pseudocysts.
Area of Science:
- Biochemistry
- Otorhinolaryngology
- Diagnostic Medicine
Background:
- Auricular pseudocysts are fluid-filled sacs on the ear.
- Accurate diagnosis is crucial for effective treatment.
- Lactate dehydrogenase (LDH) isoenzymes may offer diagnostic clues.
Purpose of the Study:
- To investigate lactate dehydrogenase (LDH) isoenzyme patterns in auricular pseudocyst fluid.
- To compare these patterns with autogenous blood.
- To assess the utility of LDH isoenzymes in diagnosing auricular pseudocysts.
Main Methods:
- Analysis of lactate dehydrogenase (LDH) isoenzyme patterns in cyst fluid and autogenous blood.
- Study conducted on twenty patients with auricular pseudocysts.
- Data collected between February 2007 and June 2010.
Main Results:
- Significantly lower levels of lactate dehydrogenase (LDH) 1 and 2 in pseudocyst fluid compared to blood (p < 0.001).
- Significantly higher levels of lactate dehydrogenase (LDH) 4 and 5 in pseudocyst fluid compared to blood (p < 0.001).
- Distinct LDH isoenzyme profiles were observed between auricular pseudocysts and autogenous blood.
Conclusions:
- Auricular pseudocyst fluid exhibits a higher percentage distribution of lactate dehydrogenase (LDH) 4 and 5.
- Auricular pseudocyst fluid shows a lower percentage distribution of lactate dehydrogenase (LDH) 1 and 2.
- Developed a laboratory method for evaluating LDH isoenzyme components, potentially improving diagnostic accuracy for auricular pseudocysts.
