Tonsillectomy seems to be a logical step in IgA nephropathy owing to the frequent tonsillitis before the beginning and the acute exacerbations of the disease. The usefulness of tonsillectomy is questionable because there are only few and short-term follow-up data after it. We followed up 35 kidney biopsy proven IgA nephropathy patients (25 men and 10 women) for an average of 12.2 yrs (range 7-32) after tonsillectomy. The values of endogenous creatinine clearance, serum creatinine, hematuria and proteinuria were compared at regular intervals during a follow-up with those obtained before tonsillectomy. We considered more than 12,000 data using 2 tailed t test. We found that proteinuria started to decrease significantly already 6 months after tonsillectomy (1.40 +/- 0.27 g/day before tonsillectomy vs 0.92 +/- 0.25 g/day after it, p < 0.05) and was significantly lower under follow-up. The tendency in microhematuria was similar (70.5 +/- 35.0 million RBC/12 hours before and 14.0 +/- 6.5 million RBC/12 hours 6 months after tonsillectomy, p < 0.0001). Furthermore, tonsillectomy stopped gross hematuria appearing in the acute exacerbation of the disease in more than two-thirds of patients. Creatinine clearance did not change in the first 2 years after tonsillectomy, however, from 2.5 years after it is significant slow and continual decrease started (117.0 +/- 9.8 ml/min before and 106.2 +/- 10.8 mil/min 2.5 yrs after tonsillectomy, p < 0.05). End-stage renal failure was detected only in 4 patients out of 35 after 10 years after tonsillectomy, in our non-tonsillectomised control group in 8 patients out of 40.

I investigated several factors that can predict the effect of tonsillectomy for the prevention of renal failure in IgA nephropathy patients. Samples were obtained from 71 patients (35 male and 36 female) who were diagnosed as having IgA nephropathy by renal biopsy and the patients were followed-up for more than 5 years. Mean age at the time of renal biopsy was 28.3 years (8-58 years), and the mean follow-up period was 9 years 9 months (5-19 years). The overall remission rate of IgA nephropathy after tonsillectomy was 28.2%, and the retention rate of renal function was 90.1%, showing a considerably better prognosis than alternative therapies previously reported. Statistical analysis of multiple prognostic factors were examined including the following: sex, age-at-biopsy, renal pathological findings, renal function, serum IgA level, hypertension, past history of tonsillitis, preoperative results of tonsillar provocation test, and the period from diagnosis to tonsillectomy. A statistically significant poorer prognosis after tonsillectomy was observed in the following conditions: < or = 20-years-old when diagnosed, serum creatinine level > or = 1.3 mg/dl, urinary protein > or = 1.0 g/day, serum IgA level > or = 350 mg/dl. No other factors affected the prognosis of renal function statistically, including past history of tonsillitis or positive result of tonsillar provocation test. The present study indicates that there is a beneficial effect of tonsillectomy for mild to moderate IgA nephropathy and that this operation may be indicated for IgA nephropathy as long as the pathological grading is not advanced. On the other hand, tonsillectomy was not effective in cases with poor renal function. Although a past history of tonsillitis and positive results in tonsillar provocation tests have been widely considered as good indicators of tonsillectomy for IgA nephropathy, the present study showed no benefit to consideration of these factors preoperatively.

We report a 29 years old female presenting with fever and painful infiltrated erythematous and violaceous plates with pseudo vesicles in the surface, located in both arms, four days after having suffered a tonsillitis. She was admitted with the diagnosis of Sweet syndrome and the lesions disappeared spontaneously. Two months later, she presented with a similar condition, again after an upper respiratory infection. Five months later, she was admitted with arthralgias with positive rheumatoid factor and antinuclear antibodies. Three years after the first admission, she was admitted with an acute glomerulonephritis and renal failure after another upper respiratory infection. Sweet syndrome was described in 1964 and, although initially considered benign, its association with inflammatory diseases or cancer has been reported.

During the period of 1995-2004, acute postinfectious glomerulonephritis was diagnosed in 322 children aged 1-16 years. An outbreak of acute postinfectious glomerulonephritis was registered in 1995, with a prevalence of 8.3 cases per 100,000 children; during 2003-2004 prevalence decreased and it was 2.2-2.4 cases per 100,000 children. Acute postinfectious glomerulonephritis was most frequently caused by upper respiratory tract infection (28.3%), following by tonsillitis (24%) and skin infection (24%). The mean interval between diagnosis of primary infection and onset of acute postinfectious glomerulonephritis was 14 days and did not differ by infection. The disease was more common in autumn (96 of the 322 cases, P<0.05). There were 4.3% of familial cases; no relapses occurred. Edema was observed in 70.3% of patients; 55.5% had elevated blood pressure according to their age. There were no proteinuria and hematuria in 17.6% and 1.7% of patients, respectively. Short-term renal failure was diagnosed in 32.9% of patients; in two cases, acute renal failure was severe and hemodialysis was started. No patient died.

Tubular occlusion from red blood cell casts secondary to immunoglobulin A nephropathy (IgAN) is a rare, serious complication of tonsillitis that can cause acute renal failure, also referred to as acute kidney injury. IgAN is the most common primary glomerulonephritis with up to 20% of cases resulting in renal failure worldwide. Tonsillectomy is an effective treatment option for patients suffering from IgAN secondary to recurrent acute tonsillitis. Tonsillectomy alone or in combination with additional medical modalities improves renal function and can have a positive effect on long-term renal survival.
