Hypothesis
Visfatin levels are altered in narcoleptic patients.
Conclusion
The study found that visfatin levels are significantly increased in narcoleptic patients, suggesting a link to disturbed immunological regulation.
Supporting Evidence
- Visfatin levels were significantly higher in narcoleptic patients compared to controls.
- The median visfatin concentration in narcoleptics was 33.7 ng/ml.
- Elevated visfatin levels were primarily observed in HLA DR2 positive narcoleptics.
- Visfatin is linked to immune modulation and inflammation.
- Previous studies have shown elevated cytokine levels in narcoleptic patients.
Takeaway
Narcoleptic patients have higher levels of a protein called visfatin, which might be related to their sleep disorder.
Methodology
The study compared visfatin levels in 54 narcoleptic patients and 39 healthy controls using enzyme immunoassay.
Potential Biases
Potential bias due to the selection of participants and the reliance on self-reported symptoms.
Limitations
The study is limited to a specific population and requires independent replication.
Participant Demographics
54 narcoleptic patients (18 males, 36 females) and 39 healthy controls (12 males, 27 females), all of Caucasian origin.
