Chronic venous insufficiency (CVI) is a multifactorial disease, commonly caused by valvular incompetence (clinically diagnosed by venous reflux) and venous hypertension.
The incidence of these factors clearly increases with patient age, and aging is one of the risk factors involved.
The activity of the PI3K/Akt/mTOR pathway is considered fundamental in vascular pathologies, and understanding its involvement would help in the development of possible therapeutic targets.
This is an observational, analytical, and prospective cohort study that reviewed 110 patients with CVI scheduled to undergo stratified saphenectomy.
They were distributed according to the presence (R=81) or absence (NR=29) of valvular incompetence (venous reflux) diagnosed clinically.
Each of the groups was further divided according to age, with a cutoff point of 50 years (NR<50=13, NR≥50=16, R<50=32, and R≥50=49).
The involvement of the PI3K/Akt/mTOR pathway, as well as that of HIF-1α and HIF-2α and of CD4+, CD8+, and CD19+ cells and mastocytes, was assessed.
Saphenous vein tissue samples obtained during surgery were processed for RT-qPCR and immunohistochemistry.
Patients with venous reflux showed a significant increase in mRNA and protein expression levels for PI3K/mTOR and HIF-1α/HIF-2α.
The number of mast cells was significantly elevated in the R group.
In distribution by age, PI3K/Akt/mTOR and HIF-1α were significantly higher in R<50 patients.
Furthermore, these patients had a significant increase in the number of CD4+, CD8+, and CD19+ cells and mastocytes in the saphenous vein wall.
These findings provide a basis for the possible existence of changes in PI3K/Akt/mTOR pathway expression in young patients, with potential accelerated asynchronous aging that is enhanced by CVI.
