This study aimed to observe the reduction ratios of the combination therapy of HD with hemoperfusion (HP) on medium molecular toxins and PBUTs in MHD patients. Methods: In this single-center observational study, 38 MHD patients were treated with HD plus HP using the Jafron KHA130 cartridge for 12 weeks. Serum concentrations of \u03b22-microglobulin (\u03b22-MG), indoxyl sulfate (IS), and p-cresyl sulfate (PCS) were measured by enzyme-linked immunosorbent assay (ELISA) at baseline and after 12 weeks, and their reduction rates were calculated. Patients were stratified by the number of HP sessions received during the study period: group A (&gt;4 times\/12 weeks, n = 16) and group B (\u22644 times\/12 weeks, n = 22). The reduction ratio of blood \u03b22-MG and PBUTs (PCS, IS) from baseline were compared between the 2 groups of patients at 12 weeks. Results: After the 12-week study period, significant reductions were observed in serum levels of \u03b22-MG (from 29.72 \u00b1 5.61\u201321.50 \u00b1 6.69 \u03bcg\/mL, t = 5.882, p &lt; 0.001; median reduction ratio 30.48%), IS (from 14.04 \u00b1 1.70\u201311.70 \u00b1 1.12 \u03bcg\/mL, t = 7.199, p &lt; 0.001; median reduction ratio 14.61%), and PCS (from 8.09 \u00b1 1.58\u20136.63 \u00b1 1.33 \u03bcg\/mL, t = 4.984, p &lt; 0.001; median reduction ratio 17.10%). There was no statistically significant difference in the reduction ratio of \u03b22-MG, PCS, and IS between group A and group B (p &gt; 0.05). The treatment was well tolerated, with only 3 episodes of hypotension that resolved with conservative management. Conclusion: Combined HD and HP therapy was associated with lower serum levels of \u03b22-MG, IS, and PCS in MHD patients, suggesting this modality may represent a viable strategy for achieving reductions in PBUT and medium molecular toxin levels. The relationship between HP session frequency and toxin reduction requires further investigation in adequately powered randomized controlled trials.<\/jats:p>","DOI":"10.1159\/000553494","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T16:00:48Z","timestamp":1785772848000},"page":"1-11","source":"Crossref","is-referenced-by-count":0,"title":["Effects
