Dr Kouyialis research has focused on Neuroendocrine dysfunction in several forms of brain insults, including traumatic brain injury, aneurismal subarachnoid hemorrhage and stroke. In November 2006 he submitted and successfully past (with excellence) his PhD, entitled “Adrenocortical dysfunction in critically ill patients with traumatic brain injury”, University of Athens Medical School, 2002.

 

The purpose of the thesis was to enquire the presence of adrenocortical dysfunction in patients sustaining a head injury, that require ICU stay, with ICP monitoring and ventilation. He included all patients admitted to the ICU in the “Evangelismos” General Hospital for a period of two years. The function of the hypothalamic-pituitary-adrenals axis was examined both in a central level (hypothalamus-pituitary) and at a peripheral level (adrenals).

 

Patients included in the study would undergo baseline cortisol and ACTH evaluation on the first day following extubation. Following that, 1μgr of synthetic ACTH was administered and a second blood sample was obtained to evaluate the stimulated cortisol levels. The following day, the patient would undergo stimulation with hCRH and the stimulated levels of the ACTH and cortisol were again evaluated. He also examined the levels of the cytokines IL-6 and TNF-a in the blood samples.

 

The results revealed that 16% of patients with severe head injury requiring ICU stay, developed adrenocortical dysfunction. In half cases this was located at the hypothalamic-pituitary level while in the remaining, the malfunction was located peripherally, at the adrenal cortex. Furthermore, he have showed that this dysfunction is statistically associated with increased levels of IL-6 in the blood, while it is not associated with the levels of the circulating TNF-a.

 

Finally, it was shown that even though there was a trend, no statistically significant association was found between the patient’s ICP during ICU treatment, his GCS on admission and his CT appearance on admission, based on Marshall’s classification. 

 

The results of Dr Kouyialis research have been published in several journals, including Stroke, Critical Care medicine and Intensive Care Medicine.
