A sharp increase in serum and CSF prolactin (PRL) values after acute metoclopramide (10 mg i.m.) administration was found in six male patients without endocrine diseases. Peak values occurred simultaneously in serum and in CSF. This finding suggests the possibility that CSF PRL content depends also on the retrograde transport from pituitary gland.

Pituitary hormone concentrations in cerebrospinal fluid in patients with prolactin and growth hormone-secreting tumors.

GH, PRL, LH, FSH and TSH were measured in serum and in cerebrospinal fluid (CSF) in 16 patients with chromophobe adenomas, in 8 with acromegaly and in 18 subjects with neurological diseases without endocrine troubles. Elevated mean GH and PRL levels in serum and in CSF were found in patients with chromophobe adenomas and with acromegaly. No constant correlation was observed between serum and CSF values. The highest hormonal levels in CSF were usually observed in adenomas with suprasellar extension, but this finding was inconstant. The determination of hormonal levels in CSF does not seem to supply any reliable information about the characteristics of pituitary tumors.

Long term therapy with recombinant interferon alpha 2 b in patients with chronic hepatitis C: effects on thyroid function and autoantibodies.

Twelve anti HCV-positive patients (8 males and 4 females; 37-62 yrs) suffering from chronic active viral hepatitis have been evaluated in order to determine serum thyroid hormones and autoantibody pattern during recombinant interferon alpha 2b (IFN-alpha 2b) therapy. The interferon was given subcutaneously three times per week for six months in a single standard dose of 3 MU. For a further six months 5 patients (Group A) received the same interferon at 1MU dose three times per week and 7 (Group B) had no treatment. Serum T3, T4, FT4, TBG, TSH, TGAb and TMAb were determined on serum collected before the start of the treatment and every month for 12 months thereafter. Except for one case, in which a transient reduction in thyroid hormone values and an increase in TSH levels was recorded, none of the patients studied showed a significant variation of serum hormonal parameters or appearance of pathological TGAb and/or TMAb levels. The data indicate that the administration of recombinant IFN-alpha 2b to HCV positive chronic active hepatitis patients at the dose and schedule employed in the present study may result in a reduction in the incidence of thyroid dysfunction related to the IFN therapy.
