[Long-term prognosis for tonsillectomy patients with IgA nephropathy]

Area of Science:

• Nephrology
• Immunology
• Otolaryngology

Background:

• Immunoglobulin A (IgA) nephropathy is a common glomerular disease.
• Tonsillectomy is a potential intervention, but its long-term efficacy in IgA nephropathy requires further investigation.

Purpose of the Study:

• To evaluate the long-term effects of tonsillectomy on IgA nephropathy patients.
• To compare clinical and histological outcomes between patients who underwent tonsillectomy and those who did not.

Main Methods:

• Retrospective study of 85 IgA nephropathy patients, divided into tonsillectomy (Group A, n=43) and non-tonsillectomy (Group B, n=42) groups.
• Follow-up period of over 5 years post-renal biopsy, with an average of 8 years and 9 months.
• Comparison of baseline characteristics, renal function (creatinine clearance, urinalysis, blood pressure), glomerular injury, and clinical/histological remission rates.

Main Results:

• Group A showed significantly higher clinical remission rates (P<0.05) and stable renal function rates (P<0.05) compared to Group B.
• Histologically, remission of minor glomerular lesions was significantly higher in Group A (P<0.05).
• Renal survival rate was higher in Group A (97.7%) than Group B (83.3%), though not statistically significant.

Conclusions:

• Tonsillectomy appears to be clinically valuable for IgA nephropathy management.
• The procedure is associated with improved long-term renal function and histological remission.
• Further prospective studies are warranted to confirm these findings.
