Prolactin and thyrotropin pituitary response to thyrotropin releasing hormone in young female heroin addicts

Spagnolli, W·1987·Drug and Alcohol Dependence

Abstract

Prolactin (PRL) and thyrotropin (TSH) serum levels were determined in a group of young female heroin addicts treated in hospital with methadone in tapered doses. At admission, from 24 to 3 h after the last dose of 'street' heroin, basal PRL values were 21 +/- 2.6 ng/ml, i.e. significantly higher (P less than 0.001) than in controls: 9.8 +/- 0.7; there was no significant differences of basal TSH values between heroin addicts and normal subjects: 2.5 +/- 0.2 vs. 2.2 +/- 0.1 mu units/ml, respectively. The day after admission, when methadone treatment was begun, the PRL and TSH pituitary response to thyrotropin releasing hormone (TRH) 200 micrograms i.v. in 12 patients was studied. The PRL response was significantly reduced (P less than 0.001) in heroin addicts vs. controls, the mean values of highest percent increments over basal were 368 +/- 41.8 and 847 +/- 80.7, respectively. The TSH response in the two groups was similar, the mean highest per cent increment over basal 393 +/- 53.4 in heroin addicts vs. 367 +/- 39.2 in controls. The increase of the PRL basal concentration and its decreased pituitary response following TRH were probably related to a change in the tuberoinfundibolar dopaminergic system (TIDA) because of a chronic intake of opiates whereas the impaired function of the dopaminergic system did not alter the thyrotropin pituitary secretion.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Basal TSH values have been reported to be lower, unaffected, or increased in chronic opioid users.

    “Furthermore, basal TSH values have been reported to be lower (149, 153), unaffected (74, 116, 136, 155-160), or increased (118, 161).”
  • Studies with dynamic thyrotropin-releasing hormone test performed in chronic opioid users have demonstrated conflicting results with enhanced, blunted, or no TSH response.

    “Studies with dynamic thyrotropin-releasing hormone test performed in chronic opioid users have demonstrated conflicting results with enhanced (118), blunted (136, 155, 156), or no (74, 157) TSH response.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
