Endogenous opioids have been implicated as a cause of secondary damage after neural injury. The basis for this statement is primarily indirect evidence from studies that demonstrate neurological or physiological improvement when opiate antagonists are given. This study directly evaluates the level of the endogenous opioid beta-endorphin in 15 patients with severe head injury. Levels of immunoreactive beta-endorphin (ir-beta E) from ventricular cerebrospinal fluid (vCSF) and serum were determined less than 24 hours after trauma. No significant correlation was found with the degree of initial injury, age, sex, or either 6- or 12-month outcome. Levels of ir-beta E from vCSF were significantly lower in patients who had received intravenous administration of morphine sulfate (48.4 +/- 5.8 versus 85.9 +/- 10.1 pg/ml, P = 0.008). No correlation was found between vCSF levels of ir-beta E and elapsed time after injury. Although vCSF and serum ir-beta E were correlated (r = 0.532, P = 0.050), the latter exhibited a different profile; the mean level of serum ir-beta E was not significantly different in those patients who received morphine, and serum ir-beta E had a significant negative correlation with time after injury (r = -0.587, P = 0.03). These results do not support a relationship between acute levels of vCSF or serum ir-beta E and the degree of neurological injury or outcome after severe head trauma. This article, therefore, is a contribution to the body of literature in which the purported detrimental effect of beta-endorphin was not demonstrated.(ABSTRACT TRUNCATED AT 250 WORDS)
