Gene and protein markers of diabetic nephropathy. C Granier, K Makni, L Molina, B Jardin-Watelet, H Ayadi and F Jarraya. Nephrol Dial Transplant (2008) 23: 792–799

Diabetic kidney disease causes significant morbidity and mortality among people with type 1

diabetes (T1D). Intensive glucose and blood pressure control have thus far failed to adequately

curb this problem and therefore a major need for novel treatment approaches exists. Multiple

observations link serum uric acid levels to kidney disease development and progression in

diabetes and strongly argue that uric acid lowering should be tested as one such novel

intervention. A pilot of such a trial, using allopurinol, is currently being conducted by the

Preventing Early Renal Function Loss (PERL) Consortium. Although the PERL trial targets T1D

individuals at highest risk of kidney function decline, the use of allopurinol as a renoprotective

agent may also be relevant to a larger segment of the population with diabetes. As allopurinol is

inexpensive and safe, it could be cost-effective even for relatively low-risk patients, pending the

completion of appropriate trials at earlier stages

he study is done to find out whether the combined use of the nutritional supplements N-acetylcysteine and Siliphos

(milk thistle extract) corrects the shedding of urine protein and oxidative damage (damage to cells and organs often

compared to fast aging) in patients with Type 2 Diabetes Mellitus (T2DM) and diabetic kidney disease.

J Am Soc Nephrol22: 1144–1151, 2011In conclusion: these results suggest that pirfenidone is a promising agent for

individuals with overt diabetic nephropathy

mean eGFR increased in the pirfenidone 1200-mg/d group (3.3 8.5 ml/min per 1.73 m2) whereas the mean eGFR decreased in the placebo group (2.24.8 ml/min per 1.73m2; P=0.026 versus pirfenidone at 1200 mg/d).The dropout rate was high (11 of 25) in the pirfenidone 2400-mg/d group,
