Background: Research shows impaired endothelial function in patients with vascular diseases and improved endothelial function following revascularization and medical treatment. There is, however, a dearth of data on the effects of different endovascular therapeutic strategies on endothelial function. We sought to compare the effects of two endovascular strategies of drug-coated balloons versus stenting on endothelial function.

Methods: The reactive hyperemia index, the ankle-brachial index, and the toe-brachial index were measured in patients undergoing endovascular revascularization preprocedurally and on the 90th postprocedural day. After adjusting for baseline line characteristics, reactive hyperemia index were compared between the two groups at baseline and at 90 days.

Results: Between January 2018 and March 2019, 86 patients were prospectively included in a non-randomized manner. Drug-coated ballooning alone was carried out on 46 patients, and bailout stenting after plain balloon angioplasty was performed on the remaining 40 patients The post-revascularization reactive hyperemia index exhibited a significant rise in both groups (1.58 ± 0.21 vs. 1.43 ± 0.20; =0.0001). There was no difference in the postprocedural reactive hyperemia index between the two treatment groups. Additionally, the follow-up reactive hyperemia index showed no significant change compared with the postprocedural reactive hyperemia index (1.58 ± 0.23 vs. 1.57 ± 0.22). The results of subgroup analysis between a group of clinically high-risk patients and a group of patients with complex lesions were similar to the aforementioned results.

Conclusions: The reactive hyperemia index was significantly improved by endovascular therapy in our study population. However, no difference was observed between drug-coated ballooning and bare-metal stenting, which highlights the effects of vessel patency on endothelial function.

Effect of hydrochlorothiazide on reducing recurrent abdominal pain in girls with idiopathic hypercalciuria.

J Res Med Sci 2011 Mar;16 Suppl 1:S433-6

Background: This study assessed the possible effect of hydrochlorothiazide (HCT) on soothing recurrent abdominal pain (RAP).

Methods: A hundred girls with RAP and IH were randomly assigned into two groups of experiment (treated with hydrochlorothiazide 1mg/kg/day) and control and all patients were followed for 3 months.

Results: In the experiment group, the mean of painful attacks in the first, second and third month were 0.38, 0.4 and 0.26, respectively which were far less than their counterparts in the control group.

Conclusions: Single daily dose of HCT is a safe and effective therapeutic option in the treatment of RAP in children with IH.
