Portal hypertension is characterized by an increase in portal pressure (> 10 mmHg) and could be a result of cirrhosis of the liver or of noncirrhotic diseases. When portal hypertension occurs in the absence of liver cirrhosis, noncirrhotic portal hypertension (NCPH) must be considered. The prognosis of this disease is much better than that of cirrhosis. Noncirrhotic diseases are the common cause of portal hypertension in developing countries, especially in Asia. NCPH is a heterogeneous group of diseases that is due to intrahepatic or extrahepatic etiologies. In general, the lesions in NCPH are vascular in nature and can be classified based on the site of resistance to blood flow. In most cases, these disorders can be explained

Tuberculosis remains one of the 'Captains of the Men of Death' even today, particularly in the developing world. Its frequency is increased 14-fold in patients with chronic liver diseases (CLD) and liver cirrhosis, more so in those with decompensated disease, probably due to the cirrhosis-associated immune dysfunction syndrome, and case-fatality rates are high. The diagnosis of tuberculosis, particularly the interpretation of the Mantoux test, is also fraught with difficulties in CLD, especially after previous BCG vaccination. However, the greatest challenge in the patient with CLD or liver cirrhosis and tuberculosis is managing their therapy since the best first-line anti-tuberculosis drugs are hepatotoxic and baseline liver function is often deranged. Frequency of hepatotoxicity is increased in those with liver cirrhosis, chronic hepatitis B and chronic hepatitis C, possibly related to increased viral loads and may be decreased following antiviral therapy. If hepatotoxicity develops in those with liver cirrhosis, particularly decompensated cirrhosis, the risk of severe liver failure is markedly increased. Currently, there are no established guidelines for anti-tuberculosis therapy (ATT) in CLD and liver cirrhosis although the need for such guidelines is self-evident. It is proposed that ATT should include no more than 2 hepatotoxic drugs (RIF and INH) in patients with CLD or liver cirrhosis and stable liver function [ChildTurcotte-Pugh (CTP) #7], only a single hepatotoxic drug (RIF or INH) in those with advanced liver dysfunction and no hepatotoxic drugs with very advanced liver dysfunction (CTP $11). A standard protocol should be followed for monitoring ATT-related hepatotoxicity and for stop rules and reintroduction rules in all these patients, on the lines proposed here. It is hoped that these proposals will introduce uniformity and result in streamlining the management of these difficult patients. ( J CLIN EXP HEPATOL 2012;2:260-270)

Hepatorenal syndrome (HRS) is the most frequent life threatening complication of advanced liver failure and cirrhosis. HRS results from a functional renal dysfunction due to circulatory disturbances in patients with advanced liver disease and portal hypertension. Reduction in the effective circulating blood volume and hence hypoperfusion of the kidney is the basic underlying common pathogenetic mechanism for the development of hepatorenal syndrome. The prognosis for HRS remains very poor with types 1 and 2-both having an expected survival time of 2 weeks and 6 months, respectively.Although the available data are derived from studies including a limited number of patients mainly affected by type 1 HRS, vasoconstrictor drugs, in particular the vasopressin analog Terlipressin, seem to be the most effective approach for the management of HRS. Associated with albumin infusion, these drugs have been shown to lead to reduced mortality and improved renal function in HRS. Terlipressin administration significantly increases mean arterial pressure and systemic vascular resistance; while the heart rate, cardiac output, HVPG and portal venous blood flow decrease significantly. This decrease correlates well with the decrease in plasma renin activity. Thus the vasoconstrictor effect of Terlipressin reverses the basic pathology of HRS by reducing the plasma renin activity. The improvement in hemodynamics with Terlipressin is associated with an increase in glomerular filtration rate and deactivation of the vasoconstrictor and sodium-conserving hormones with reduced activity of the RAAS resulting in increased natriuresis.Terlipressin thus reverses HRS and is useful in bridging the patient to liver transplantation and may hence indirectly improve survival. Patients with HRS who show an improvement in renal function with Terlipressin and albumin seem to have an excellent posttransplantation outcome similar to that of patients without HRS. Thus, the use of Terlipressin has been shown to be safe, with minimal side effects that usually disappear after dose reduction, and results in an improved outcome in patients with HRS. Key words Conflict of interestNo conflict of interest to disclose.Hepatorenal Syndrome (HRS) was first recognized in cirrhosis by Hecker and Sherlock in 1956. 1 All nine of their patients died, with postmortem examination of the kidneys showing normal histology. They proposed that HRS is caused by a reduction in renal perfusion secondary to systemic arterial vasodilation.HRS is now increasingly being recognized as a form of renal dysfunction in the setting of liver failure. It is the most frequent fatal complication of cirrhosis with nearly 50% of patients dying within 2 weeks of this diagnosis.2 Development of ascites in patients with MELD scores of Յ10 is associated with an 8% and 11% risk of HRS at 1 and 5 years, respectively.3 At a MELD score of 18 or more nearly 40% of patients are expected to develop HRS within a year. 4 HRS has also been seen in 30% of patients with severe acute alcoholic hepatitis a...

We herein report a patient with decompensated cirrhosis secondary to autoimmune hepatitis, who presented with pneumatosis intestinalis (PI) and portal venous gas. Mesenteric ischemia has been recognized as a common and life-threatening cause of PI which portends a grave prognosis. The patient was found to have bacterascites and recovered after appropriate antibiotic therapy. Spontaneous bacterial peritonitis/bacterascites with gas-forming organisms manifesting as PI has not been previously reported.

Background. Nonresectable neuroendocrine tumour (NET) liver metastases respond poorly to most widely available and used therapies. Selective Internal Radiation Therapy (SIRT) is becoming recognized as a new modality for selectively treating non-resectable liver tumours. This paper presents an experience of 14 patients with non-resectable NET liver metastases treated with SIRT. Methods. Between September 1997 and October 2009 14 patients with extensive NET liver metastases were treated with 2.0 to 3.0 GBq of 90Yttrium microspheres. Repeat SIRT was undertaken in three patients after 16, 27, and 48 months, respectively. Responses were assessed clinically, biochemically, and with serial CT scans. Survival was measured from initial SIRT. Results. Some response was seen in all 14 patients. Carcinoid syndrome improved or resolved in 10/10 instances. 24-hour urinary 5-HIAA or serum chromogranin A levels fell dramatically in 5/7 patients following SIRT. Serial CT scans revealed partial response or stable disease in all 14 patients. Repeat treatment in three patients experiencing progression was associated with a further response. Median survival after SIRT is 25 months with 6 patients being alive (and 3 patients still asymptomatic), at 19, 22, 23, 23, 58, and 60 months. Conclusions. SIRT is an effective and well-tolerated treatment for non-resectable NET liver metastases capable of both alleviating the carcinoid syndrome and achieving significant tumour regression. Repeat treatment is an option and liver resection after downstaging may also become possible.

Thus aggressive therapy in such patients with gall bladder cancer may be warranted in select cases. Also, the gall bladder specimens in patients undergoing surgery for cholangiocarcinoma should be analyzed in detail to identify foci of dysplasia or change in the epithelium. The pathogenesis may be due to a common field change in the biliary epithelium.

Spontaneous bacterial peritonitis (SBP) is a common cause of morbidity and mortality in patients with advanced cirrhosis and portal hypertension. While gramnegative rods and Enterococcus species are the common offending organisms, Salmonella has also been recognized as a rare and atypical offending organism. Atypical features of Salmonella SBP include both its occurrence in cirrhotic patients with immunosuppressive state and its lack of typical neutroascitic response. Diagnosis is often delayed as it requires confirmation from ascitic fluid culture. We report a case of Salmonella SBP occurring in a patient with decompensated cryptogenic cirrhosis with concurrent low-grade non-Hodgkin lymphoma and prior treatment with rituximab. Physicians should be aware of the atypical presentation, especially in cirrhotic patients who are immunosuppressed.
