NO
To clarify changes in serum APRIL levels before and after Epipharyngeal Abrasive Therapy (EAT) in patients with IgA nephropathy.
Others
This study aims to explore changes in immunological and clinical markers (BAFF, Gd-IgA1, uromodulin, urinalysis findings, renal function, and endoscopic epipharyngeal findings). It is an exploratory observational study and does not evaluate efficacy or safety.
Change in serum APRIL levels between baseline (before initiation of EAT) and after 12 EAT sessions
Change in serum BAFF levels
Change in serum Gd-IgA1 levels
Change in serum uromodulin levels
Change in urinalysis findings (dipstick and RBC/HPF)
Change in serum creatinine and eGFR
Change in endoscopic epipharyngeal findings (reference evaluation)
Observational
| 15 | years-old | <= |
| 70 | years-old | >= |
Male and Female
Patients aged 18 years or older
Diagnosed with chronic epipharyngitis and undergoing EAT as part of routine clinical care
Patients with active IgA nephropathy, remission-phase IgA nephropathy, or non-renal disease controls
Able to undergo blood tests, urinalysis, and endoscopic evaluation at baseline and after 12 EAT sessions
Provided written informed consent for study participation
Patients with acute inflammatory diseases such as acute epipharyngitis, acute sinusitis, or acute tonsillitis
Patients unable to undergo scheduled blood tests, urinalysis, or endoscopic evaluation
Patients for whom EAT is medically inappropriate (e.g., severe gag reflex, bleeding tendency)
Patients with severe systemic diseases (e.g., heart failure, liver failure, malignancy) that may interfere with study participation
Pregnant women or those with possible pregnancy
Any patient deemed unsuitable for participation by the principal investigator
