Course of sepsis in rats with thyroid dysfunction.

OBJECTIVE

Numerous studies show the relationship between sepsis and thyroid hormones. Virtually all these studies investigate changes in post-sepsis thyroid hormones and the relationship between these changes and the progression of the disease. Our aim in this study was to investigate the progression of sepsis in rats with thyroid dysfunction.

MATERIAL AND METHODS

The study involved four groups, each containing seven female Wistar albino rats: Group 1: Sham, Group 2: Control (Sepsis), Group 3: Hyperthyroidism-Sepsis, and Group 4: Hypothyroidism-Sepsis. Group 1 only received laparotomy. Group 2 only had sepsis. Sepsis was induced in Group 3 and Group 4 following formation of hyperthyroidism and hypothyroidism, respectively. After 24 hours, relaparotomy and thoracotomy were performed, and tissue and blood samples were drawn.

RESULTS

Dysfunctions seen in the liver, lungs, and kidneys during sepsis and other findings of sepsis were milder in the hyperthyroidism group in comparison to both the control and hypothyroidism groups.

CONCLUSION

The results of Simon's grade, histopathological organ damage, and laboratory parameters revealed that the progression of sepsis was milder in the hyperthyroid group than in the hypothyroid and euthyroid groups. The progression in the hypothyroid group was the most severe. Therefore, the results of the study raise the question of whether immediate treatment in cases of hypothyroidism and slow return of thyroid function to normal levels in cases of hyperthyroidism are adequate treatment approaches in patients who may develop sepsis or septic shock." To determine the answer to this question, more detailed studies are required with a higher number of subjects.
