   Abstract 

Hepatorenal syndrome (HRS) is the most appalling complication of acute or chronic liver disease with 90% mortality rate. Single pass albumin dialysis (SPAD) can be considered as a noble liver support technique in HRS. Here, we present a case of a young healthy patient who developed hyperacute fulminant liver failure that progressed to HRS. The patient was offered SPAD as a bridge to liver transplantation, however, it resulted in an excellent recovery.

   Introduction Top


Single pass albumin dialysis (SPAD) is a unique and effective form of liver support technique that has been underestimated up till now. In comparison to the conventional liver support devices such as molecular adsorbent recirculation system (MARS), SPAD is less expensive and involves use of a regular hemodialysis machine.


   Case Report Top


A 24-year-old Saudi man was admitted with a two days complaint of diffuse abdo≠minal pain and yellow discoloration of the sclera. His past medical history was un≠remarkable. There was no history of animal contact, alcohol abuse, or recent travel. The physical examination was remarkable for fever, jaundice, and severely tender epigas≠trium with positive shifting dullness in the abdomen. However, it was not remarkable for hepatosplenomegaly or signs of hepatic encephalopathy. Initial laboratory investigations revealed hemoglobin 10.4 g/dl, White cell count 6.1x10 3 /ĶL, platelets 104x10 3 /ĶL, serum Na + level: 127mmol/L, K + : 4.4 mmol /L, Urea:17.2 mmol/L, Creatinine: 850 Ķmol/L, ALT: 5225 U/L, AST: 2922 U/L, and Gamma GT:195 U/L. Other investi≠gations revealed positive Hepatitis A (Hep A) IgM, negative serological tests for  Brucella More Details, Epstein Barr virus (EBV), Hepatitis B, Hepatitis C, and HIV; negative toxicology screen for paracetamol; negative serological tests for autoimmune disease; serum IgA level was within normal; 24-hour urinary volume 744 ml with a total Protein of 0.34 g and creatinine clearance of 8 ml/dl. On 2 nd day after admission to hospital, the patient's condition deteriorated, and he developed hepatic encephalopathy, but maintained normal hemodynamic signs. Both the com≠puterized tomography scan (CT scan) of brain and the ultrasound of the kidneys were normal. The INR of prothrombin increased to 4-5. The patient was diagnosed as hyperacute fulminant hepatic failure secondary to hepatitis A viral infection and complicated by hepatorenal failure. Although, the patient received fluid challenge, the renal function did not improve. Liver trans≠plantation was contemplated but unfortu≠nately no donor could be arranged. In the meanwhile, conventional hemodialysis was provided to treat the metabolic derangement and fluid overload associated with anuria. However, the patient continued to dete≠riorate. Hence, an alternative supportive technique was required, and SPAD was selected as a mode of therapy with the following protocol: we used Aquarius Plati≠nium CRRT machine with Aquamax 19 solutions (Baxter Health systems) with access to circulation through a femoral double lumen catheter without heparin. We adop≠ted continuous venovenous hemodialysis (CV-VHD) mode with 2 Liters/hour dialysate flow and albumin added in alternate dia≠lysate infusion bags to produce a concen≠tration of 4% albumin per liter of dialysate. We modified ultrafiltration to maintain balance of input and output of fluids. We applied the albumin dialysate in 6-hours daily sessions and continued the CRRT without albumin for the rest for the day, hence we named our protocol SPAD. The circuit design is shown in [Figure - 1]. We changed dailyzers every 48 hours as re≠commended by manufacturer. After 4 days of SPAD and CRRT, the patient had excellent bio-chemical profile, reduction of INR and dramatic improvement of liver function as shown in the [Figure - 2].


   Discussion Top


Hepatorenal Syndrome (HRS) is a rever≠sible functional renal impairment that occurs in patients with advanced liver cirrhosis or those with fulminant hepatic failure. [1] Our patient presented all major diagnostic criteria of HRS. [2] Our patient fitted into type 1 HRS, which has higher mortality than type 2.

[Figure - 3] summarizes the indications of liver support. [3] Standard management of HRS includes maintenance of MAP 85-90 mmHg by volume expansion with albumin. [4] Various pharmacological agents such as terlipressin, [5],[6] ornipressin, midodrane, [7],[8] pentoxifylline, [8],[9] and octreotide, [7],[8] have also been used with success.

Transjugular intrahepatic portosystemic shunt (TIPS) [8] is a better method of treatment of ascitis than controlled paracentesis or the obsolete Denver or Leveen's Shunt that cause increased mortality and morbidity. However, TIPS is contraindicated in pa≠tients with severe encephalopathy and patients with high prothombin time >100. As our patient had minimal ascitis, with severe coagulopathy, and grade 4 encepha≠lopathy, paracentesis or TIPS were not indicated. Of the liver systems, we selected the readily available hemodialysis modality SPAD with CRRT modification. [17],[18],[19],[20],[21] Recently, similar finding with the use of SPAD has been described, and also the results of SPAD and MARS were com≠parable. [22] However, SPAD has a simpler circuit compared to MARS, [Table - 1]. Though, the principal of both methods is the same (ie. to remove albumin bound toxins), in SPAD albumin is not recir≠culated. Fractionated plasma separation (Prometheus system) has also been intro≠duced, [20] which is based on patients' albumin separation through an albumin permeable membrane, and then the albumin bound toxins are removed by the raisin chambers. Here, the patients albumins are cleaned and returned back. This process does not require any exogenous albumin in the circuit. Initial studies are promising. The circuit sign is in comparison with MARS in [Figure - 4]. The different methods and devices used as liver support systems is summarized in [Table - 2]. Recently, there is further modification of SPAD in the form of single pass albumin extended dialysis (SPAED) that requires two dialyzers con≠nected one over the other. The first one being a hemodialysis dialyzer, and the second one is for albumin dialysis where the albu≠min is passed along the dialyzer side at a rate of 30 ml/hr. This modality is currently under review. [23] Nevertheless, when it comes to cost effectiveness, the cost per treatment by SPAD is far less then MARS in US dollar (USD); each MARS treatment costs approximately 1700 USD, where as SPAD costs only 600 USD.

We conclude that SPAD is an extremely simple technique, as it can be used with the existing hemodialysis machine, can be ope≠rated by nursing staff who can handle routine hemodialysis machine and a cheaper option as compared to MARS. It has been shown to reverse HRS in case studies inclu≠ding ours. Moreover, it has been compared with MARS and found to be equally effect≠tive. However, its efficacy has been under≠estimated, hence could not get a global use as the MARS liver support system. As there is huge collection of data on MARS it is premature to regard SPAD superior to MARS. Nevertheless, a greater future use of SPAD will probably proof its efficacy comparable to MARS. The Newer systems such as Prometheus or SPAED are pro≠mising but are more expensive than SPAD.


   Questions and Comments Top


Dr Akram Askar (King Khaled Uni≠versity Hospital, Chairman of the RNTC):

I would like to thank Dr. Ebadur Rahman for his presentation, and the floor is open for questions.

Audience: You mentioned that late appli≠cation of the liver support devices has poor outcome. Do we have evidence for that?

Dr. Ebadur Rahman: The case and un≠controlled reports suggest that but we do not have a prospective trial yet to confirm it. I believe it will confirm the suggested notion that advanced encephalopathy se≠condary hepatic failure is associated with poor outcome.

Dr. Al Swaida: I would like to comment on the availability of liver allografts for trans≠plantation. There is a universal shortage of organ donation that renders the need for liver support devices mandatory. The deve≠lopment of such devices is promising.

Professor Jamal Al Wakeel: What about the use of dopamine in the context of albu≠min dialysis in patients with hepatorenal syndrome?

Dr. Ebadur Rahman: There are some obser≠vations and theoretical benefit in improving the renal perfusion but prospective studies are required to confirm them.

Audience: Would you elaborate on the design of the single pass albumin extended dialysis (SPAED) in comparison to SPAD?

Dr. Ebadur Rahman: SPAED device has two dialyzers connected in series, one that runs regular dialysate in it and the following runs the albumin. So the patient has regular and albumin dialysis at the same time, while SPAD device has one dialyzer that allows regular dialysis and albumin dialysis together.

Dr. Askar: Thank you for the attendance.
