Consecutive patients with ACLF (Acute on Chronic Liver Failure) and septic shock with AKI (Acute Kidney Injury) who give written informed consent will be included in this prospective trial at ILBS. At baseline s, endotoxin levels, NT-Pro BNP, , urine N-GAL will be done for all patients. A 10 ml serum sample will be stored for doing a cytokine profile. Septic shock will be defined by the presence of two or more diagnostic criteria for the systemic inflammatory response syndrome, proven or suspected infection with hypotension non-responsive to adequate fluid resuscitation assessed by no evidence of stroke volume variation on flow track and need of a vasopressor to achieve a target mean arterial pressure (MAP) of ≥ 65 mm Hg. A record of CVP, IVC diameter and B-lines on ultrasound lung would also be done. Patients with age less than 18 years, severe known cardiopulmonary disease (structural or valvular heart disease, coronary artery disease, COPD) pregnancy, chronic kidney disease, patients already meeting emergency criteria for immediate hemodialysis at the time of randomization as specified in the late group, patients transferred from other hospitals who have already been on hemodialysis before their arrival in the intensive care unit, extremely moribund patients with an expected life expectancy of less than 24 hours, failure to give informed consent from family members.

Inclusion Criteria:

- Patients with ACLF defined based on APASL criteria with septic shock associated AKI

• Patients already meeting emergency criteria for immediate hemodialysis at the time of randomization as specified in the late group (serum potassium>6 meq/lt, metabolic acidosis ph<7.12, acute pulmonary edema, severe volume overload with hypoxemia non-responsive to diuretic treatment)
• Patients transferred from other hospitals who have already been on hemodialysis before their arrival in the intensive care unit
• Extremely moribund patients with an expected life expectancy of less than 24 hours
• Failure to give informed consent from family members.
• Hemodynamic instability requiring very high dose of vasopressors
