BACKGROUND: This study aims to investigate the role of telomerase activity in the risk of primary spontaneous pneumothorax, which is most frequently encountered in the practice of thoracic surgery.
METHODS: A total of 61 patients (56 males, 5 females; median age: 29.4 years; range, 17 to 43 years) who underwent treatment for primary spontaneous pneumothorax and 19 age- and sex-matched healthy controls (10 males, 9 females; median age: 29.1 years; range, 23 to 43 years) were included in this prospective study between January 2018 - August 2018. Telomerase activity was evaluated with enzyme-linked immunosorbent assay. The correlation between telomerase activity and clinical and demographic parameters was examined.
RESULTS: The mean serum telomerase level was 3.4±0.6 ng/mL in the primary spontaneous pneumothorax group and 1.9±0.5 ng/mL in the control group, indicating significantly higher levels in the patient group (p<0.001). There was no significant association between the telomerase levels and presence of blebs and/or bullae on thoracic computed tomography, extent of pneumothorax, laterality (right, left, or bilateral), and pack years of cigarette smoking.
CONCLUSION: Telomerase levels of patients with primary spontaneous pneumothorax are significantly higher than healthy individuals. Future genetic studies may ultimately clarify a potential relationship between primary spontaneous pneumothorax and short telomere syndrome.
