title: Paradoxical GH response to TRH during status epilepticus in man.
abstract: Information on GH in relation to epilepsy is sparse, and to our knowledge there is no information on GH levels during status epilepticus in man. We studied GH in serum in six patients during status epilepticus, and in a control group of six seizure-free patients with epilepsy, before and after injection of TRH. The baseline GH values before TRH administration were within the normal range in all patients. After injection of TRH all patients with status epilepticus showed a paradoxical peak-shaped increase of GH to at least twice their baseline levels within 45 min after the injection (median basal GH value 1.5 mU/l and median peak GH value 6. 5 mU/l, mean increase 330%). No uniform reaction to TRH was observed in the control group (median basal GH value 2.7 U/l and median of the highest value within 45 min 5.2mU/l). A paradoxical peak reaction of GH to TRH was significantly more frequent in the status epilepticus group compared with the control group (P=0.008, Fisher exact probability test). TRH is not considered a GH-releasing hormone in humans during normal conditions, but a paradoxical response of GH to TRH, similar to that observed during status epilepticus, has been reported in various other pathological conditions, such as acromegaly, liver cirrhosis, mental depression and hypothyroidism. Our results of GH release after TRH administration in patients with status epilepticus suggest an altered regulation of GH as a result of the long-standing epileptic activity.
