Proteinuria
Conditions
Brief summary
The study aims to explore the non-pharmacological treatment of IgA nephropathy by weight reduction. The investigators hypothesized that benefits of weight loss may reduce proteinuria.
Detailed description
This is a prospective randomized study in adult IgA nephropathy. The investigators enrolled 30 patients who have proteinuria exceeds 1 g per day with biopsy proven IgA nephropathy. The experimental arm recieves the non-pharmacological treatment, weight reduction protocol. All patients in this arm must be reduce their body weight in 3-5 % from baseline as protocol. Another arm is control group which recieves standard treatment of IgA nephropathy including ACEIs/ARBs for blood pressure control (target \< 130/80 mmHg). The primary outcome is proteinuria level. The secondary outcome is cytokines and inflammatory markers level including interleukin-6, resistin, adiponectin, leptin and monocyte chemoattractant protein-1.
Interventions
1. Set target daily energy requirement by nutritionist (25-30 Kcal/Kg/day minus 500 Kcal) 2. Advice and encourage patients to do aerobic exercise at least 30 minutes/day for 4-5 days/weeks. 3. Daily body weight measurement. 4. Record food diary

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage change of 24-hour proteinuria | 6 months | The investigators measure amount of 24-hour proteinuria at randomization peroid ( as baseline), first, third and sixth month. Then, investigators calculate the percentage reduction of proteinuria at different time points. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| plasma concentration of IL-6, adiponectin, resistin, leptin, MCP-1 | 6 months | The investigators measure amount of plasma concentration of IL-6, adiponectin, resistin, leptin, MCP-1 at randomization peroid ( as baseline) and sixth month. Then, investigators calculate the percentage reduction of these cytokines in 6 months peroid. |
