Resumen
Descripción general del contenido del recurso.
There is very scarce information concerning prolactin (PRL) serum concentrations under pathologic conditions in dogs. To describe the relationship between PRL and thyroid hormones serum concentrations forty-five cross- and pure-bred male and female dogs with clinical suspicious of hypothyroidism were blood sampled for PRL and thyrotropin (TSH), thyroxin (T4) and/or free T4 (FT4) serum determinations. Prolactin concentrations in hypothyroid and euthyroid dogs were compared by the Mann-Whitney test. For further description of data correlation analyses between PRL and TSH, FT4 or T4 were also tested. Percentage PRL change was calculated in the patient in which the TRH stimulation test was carried out. Overall serum PRL concentrations in hypothyroid (n= 34) and euthyroid (n= 11) dogs were 25.9±4.8 and 14.6±6.5 ng/ml, respectively (p >0.05). No significant correlation could be found between PRL and the different thyroid hormones in any group. The stimulated dog was classified as subclinical a hypothyroid (grade I). Prolactin increased 5 times (from 0.4 to 2.1 ng/ ml) after TRH injection in this animal. Further work should be done to describe prolactinemia in canine hypothyroidism.
