[An IgA nephropathy case with highly reduced urinary protein concomitant with reduced obesity].
We reported a case of a 38-year-old woman with both massive proteinuria and severe obesity. We diagnosed her as metabolic syndrome from her waist size of over 90 cm around her umbilicus, hyperlipidemia (high TG level) and hypertension. The urinary protein was more than 3.5 g/day and body mass index was 38.7 at admission. The renal biopsy specimen revealed IgA nephropathy. According to Clinical guidelines of IgA nephropathy 2nd version, Committee of IgA Nephropathy-the Special Study Group on Progressive Glomerular Disease, the Ministry of Health, Labor and Welfare of Japan-, her prognosis belonged to a rather poor group. We planed to administer steroid treatment first, however considering the adverse effects of steroid therapy, such as hyperlipidemia and diabetes mellitus, we tried to decrease her body weight as much as possible, and then treated her with both angiotensin converting enzyme inhibitor and anti-platelet drug. After her body mass index (body weight) was approximately 30.1 % (30 kg) less than that on admission, a parallel reduction of urinary protein was observed, and the final level was approximately 0.18 g/day. Decline in the body weight, diet and exercise were the chief measures that reduced the urinary protein without corticosteroid therapy.
