The Effects of Nitazoxanide in Hepatic Encephalopathy
The Effects of Nitazoxanide in Hepatic Encephalopathy
Evaluating the efficacy and safety of nitazoxanide in comparison to standard treatment in
 patients with grade II-III hepatic encephalopathy (HE). Also, Evaluating the effect of
 administering nitazoxanide on the improvement of patient's quality of life.
Nitazoxanide (NTZ) is a thiazolide anti-infective with activity against anaerobic bacteria,
 protozoa and viruses. A pilot prospective study at the 2008 American Association for the
 Study of Liver Diseases meeting showing clinical improvement in HE among cirrhotic patients
 who received nitazoxanide and lactulose. Based on the excellent safety profile of NTZ, the
 present pilot study is conducted hopefully to prove the efficacy of nitazoxanide in treating
 patients experiencing HE grade II-III.

 Study design:The study is Prospective, Randomized, Controlled, Open-Label, Pilot study.

 Method: The study will include a total of 36 patients with grade II-III Hepatic
 Encephalopathy, and an informed consent will be obtained from every patient before being
 included.

 All the patients will receive oral lactulose, plus either nitazoxanide, metronidazole or
 rifaximine.

 A- All patients will be subjected to the following at baseline:

 -  Patient's full history

 -  Liver disease staging using Model for End stage Liver Disease (MELD) score

 -  Measurement of serum electrolytes (Na+, K+, Ca2+)

 B- All patients will be subjected to the following at baseline and at the end of treatment:

 -  Measuring Blood ammonia level

 -  Measuring liver function tests (AST, Total bilirubin, international normalized ratio
 (INR), Serum albumin, prothrombin time (PT)), serum creatinine and complete blood count
 (CBC)

 -  Assessing severity of Hepatic Encephalopathy using Clinical Hepatic Encephalopathy
 Staging Scale (CHESS)

 C- Monitoring tolerability up to 30 days after the last dose D- Assessment of quality of life
 using Chronic Liver Disease Questionnaire (CLDQ)
Inclusion Criteria:

 -  Adult Patients from 18 to 65 years.
