Zusammenfassung
Bei 8 Patienten mit asymptomatischem, exogen allergischem Asthma bronchiale wurden die Plasma-Nor-Adrenalin(NA)- und die Adrenalin-(A)-Spiegel in Ruhe und sofort nach Belastung bestimmt. Die Patienten hatten in Ruhe einen normalen Bronchialwiderstand und entwickelten unter Belastung eine deutliche Bronchokonstriktion (BIB), die durch eine vorangehende Alpha-Rezeptorenblockade mit Phentolamin verhindert werden konnte. Bei 7 Kontrollpersonen wurden die NA- und A-Spiegel auch nach Beta-Rezeptorenblockade mit Propranolol gemessen.
Die folgenden Ergebnisse wurden erzielt:
-
1.
Die NA-Spiegel zeigten in Ruhe keine signifikanten Unterschiede zwischen den Gruppen. Nach Belastung wurde bei allen Gruppen ein Anstieg des NA beobachtet, der jedoch bei den Patienten auch nach Phentolamin und bei den Normalpersonen nach Propranolol signifikant höher ausfiel als bei der Kontrollgruppe im Leerversuch.
-
2.
Die A-Spiegel zeigten in Ruhe und nach Belastung keine signifikanten Gruppenunterschiede. Die Belastung führte zu keinem signifikanten A-Anstieg, außer bei der Normalgruppe nach Propranolol.
-
3.
Zwischen den NA-Spiegeln nach Belastung und dem belastungsinduzierten Anstieg des Bronchialwiderstandes bestand keine signifikante Korrelation.
Es wird angenommen, daß 1. bei Asthmatikern unter Belastung die Sympathikusaktivität gesteigert ist und 2. die Provokation der BIB durch die unter Belastung gesteigerten NA-Spiegel unwahrscheinlich ist.
Summary
Plasma nor-epinephrine (NE) and epinephrine (E) levels at rest and immediately after exercise were estimated in 8 patients with asymptomatic extrinsic allergic bronchial asthma. The patients had a normal airway resistance at rest and developed a marked bronchoconstriction (EIB) during exercise, which could be prevented by previous alpha-adrenergic blockade with phentolamine. In 7 control persons NE and E levels were measured also after beta-adrenergic blockade with propranolol.
The following results were obtained:
-
1.
At rest NE levels showed no significant differences between the groups. After exercise an increase of NE was observed in all groups, but in patients, even after phentolamine, and in normals after propranolol the increase was significantly higher than in the normal group within the control test.
-
2.
No significant differences between the groups were found in E levels at rest and after exercise. Exercise caused no significant increase of E levels, except in the normals after propranolol application.
-
3.
No significant correlation existed between NE levels and the increase of airway resistance after exercise.
It is concluded that during exercise in asthmatics the sympathetic activity is enhanced, but the provocation of an EIB does not seem to be mediated by enhanced plasma NE levels.
