Total opioid peptide receptoractivity in human cerebrospinal fluid is measured in patients who are experiencing lower back pain. Desalted CSF is eluted from a C18 Sep‐Pak and is subjected to a radioreceptorassay (RRA) that employs tritiated etorphin, which is aligand that is effectively displaced by opioids from several different types of opioid receptors. Three clinical groups have significantly different endogenous levels of 2.4, 4.5, and 6.4 pmol of methionine enkephalin‐equivalents per mL CSF. Those three levels indicate that more opioid activity is correlated with the amount of drug to relieve the patient's perception of pain. When the total opioid content exceeds an empirical threshold, the sample is further fractionated with gradient reversed phase HPLC, and the opioid receptoractivity in each HPLC fraction is measured to determine the characteristics pattern of those receptoractive opioid peptides present in that patient's CSF. Different HPLC RRA patterns are found for different clinical categories. A possible interpretation of these two different sets of data‐is that a lesion exists in one or several of the opioid peptidergic systems (metabolism, receptors) in this particular patient population.
