Summary
Background
Primary biliary cirrhosis (PBC) is a chronic, progressive liver disease with elevated serum lipids. It remains unclear if hyperlipidemia increases the risk for atherosclerosis in PBC patients. Metabolic syndrome (MS) promotes the development of atherosclerotic cardiovascular disease due to abdominal obesity and insulin resistance.
Aims
The aim of this study was to assess incidence and parameters of MS, as well as subcutaneous and visceral fat using noninvasive ultrasonographic measurement in patients with PBC in our population.
Methods
We included 55 patients with PBC and 44 age- and sex-matched healthy controls (CG-control group). Anthropometric measurements (weight, height, and waist circumference), age, sex, and body mass index were recorded for patients and controls. Laboratory tests for assessing MS and liver function tests were analyzed. We used ultrasonography to determine subcutaneous and visceral fat diameter and area (SF, VF and SA, VA, respectively), as well as perirenal fat diameter (PF).
Results
Patients with PBC had significantly higher levels of cholesterol and liver function tests. There were no statistically significant difference in serum insulin and HOMA levels, as well as incidence of MS was diagnosed in 30.9 % (17/55) PBC patients and 43.2 % (19/44) controls. We registered lower amount of VF (PBC:10.92 ± 3.63 mm, CG:16.84 ± 5.51 mm,p < 0.001), VA (PBC:403.64 ± 166.97 mm2, CG:720.57 ± 272.50 mm2,p < 0.001), and PF (PBC:7.03 ± 1.82 mm, CG 10.49 ± 2.70 mm,p < 0.001) in patients with PBC.
Conclusion
MS is not more frequent in patients with PBC compared with healthy volunteers in our population. Lower amount of VF could be related to lower risk for cardiovascular events in PBC patients.
Zusammenfassung
Hintergrund
Die primär biliäre Lebercirrhose (PBC) ist eine chronisch progressive Lebererkrankung mit Erhöhung der Lipide. Es besteht Unklarheit darüber, ob diese Hyperlipidämie das Risiko für eine Atherosklerose bei PBC Patienten erhöht. Das metabolische Syndrom (MS) begünstigt die Entwicklung einer kardiovaskulären Atherosklerose durch die dabei bestehende abdominale Obesitas und Insulinresistenz.
Ziel der Studie
war es, das Vorkommen eines MS, sowie Parameter desselben bei PBC Patienten im Vergleich mit der Normalbevölkerung zu erfassen, wobei das subkutane und viszerale Fett ultrasonographisch gemessen wurde.
Methodik
Wir schlossen 55 Patienten mit PBC und 44 gesunde – alters und geschlechts-gematchte – Kontrollen (CG-Kontrollgruppe) in die Studie ein. Anthropomorphometrische Messdaten (Gewicht, Körpergröße, Hüftumfang), Alter, Geschlecht und Body Mass Index wurden bei den Patienten und der Kontrollgruppe festgehalten. Laboruntersuchungen zur Erfassung des MS und Leberfunktionsproben wurden durchgeführt. Das subkutane (SF) und viszerale Fett (VF), deren Durchmesser und Fläche (SA, VA) sowie der Durchmesser des perirenalen Fettgewebes (PF) wurde ultrasonographisch erhoben.
Ergebnisse
Patienten mit PBC hatten signifikant erhöhte Cholesterin- und Leberfunktionsproben. Die Serum Insulin und HOMA Spiegel, sowie das Vorkommen eines MS (17 von 55 (30,9 %) PBC Patienten vs 19 von 44 (43,2 %) CG Kontrollen) unterschieden sich nicht signifikant in beiden Gruppen. Wir registrierten einen niedrigeren Gehalt von VF (PBC:10.92 ± 3.63 mm, CG:16.84 ± 5.51 mm,p < 0.001), VA (PBC:403.64 ± 166.97 mm2, CG:720.57 ± 272.50 mm2 p < 0.001), und PF (PBC:7.03 ± 1.82 mm, CG 10.49 ± 2.70 mm,p < 0.001) bei den PBC Patienten.
Schlussfolgerung
Das MS ist kommt bei Patienten mit PBC nicht häufiger als bei der Normalbevölkerung vor. Der von uns beobachtete niedrigere Anteil an viszeralem Fett könnte für ein niedrigeres Risiko kardiovaskulärer Ereignisse bei PBC Patienten sprechen.
