  1. 01HumanNon-randomized trialEfficacy outcome

    In patients with hyperthyroidism or hypothyroidism, an intravenous VIP bolus significantly stimulated prolactin secretion in both the dysthyroid and euthyroid states.

    In plain wordsIn patients with thyroid disease, a VIP injection raised prolactin levels, both before and after thyroid treatment.

    Summary
    although the peptide was able to significantly stimulate PRL secretion during both the dysthyroid and euthyroid states of hyper- and hypothyroid patients
    1 context sentence
    Summary · context
    Eight female patients with Graves' disease and 8 females with chronic thyroiditis received intravenous bolus injections of VIP (100 micrograms) and TRH (500 micrograms) 2-3 days apart from each other, during both the dysthyroid and euthyroid (attained by medical treatment) states.
  2. 02HumanNon-randomized trialEfficacy outcome

    In patients with hyperthyroidism or hypothyroidism, prolactin responsiveness to VIP was essentially the same regardless of thyroid status.

    In plain wordsIn patients with thyroid disease, the prolactin rise after VIP was about the same whatever their thyroid state.
