The role of TLRs was evaluated using an ischemia/reperfusion (I/R) model in TLR2Ϫ/Ϫ and ϩ/ϩ mice . Significantly fewer granulocytes were present in the interstitium of the kidney 1 day post-I/R in the TLR2Ϫ/Ϫ mice and fewer macrophages were present 1–5 days after I/R. Kidney homogenate cytokines KC, MCP-1, interleukin-1␤ (IL-1␤), and IL-6 were also significantly lower in the TLR2Ϫ/Ϫ animals as compared to the TLRϩ/ϩ mice. Hence the absence of TLR2 clearly had an anti-inflammatory effect on the response to I/R.
In order to meet the need for a uniform definition which included different severity grades of AKI the RIFLE classification was developed by ADQI . This classification system (table 1) has now been validated in numerous settings . Epidemiology of AKI and ARF ARF ARF severe enough to require RRT occurs in approximately 5% of general ICU patients . g. cardiac surgery versus medical ICU but appears to be surprisingly uniform around the world. Over a period of almost 20 years the incidence of ARF treated with RRT has more than doubled.

Each of these treatments should be considered after the resolution of infection, since HRS may reverse following effective antibiotic treatment in a significant number of patients. Liver Transplantation Liver transplantation is the treatment of choice for patients with type-1 HRS .
