We carried out a molecular characteristic-based epidemiological survey of various hepatitis viruses, including hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis E virus (HEV), and GB virus C (GBV-C)/hepatitis G virus (HGV), in Myanmar. The study population of 403 subjects consisted of 213 healthy individuals residing in the city of Yangon, Myanmar, and the surrounding suburbs and 190 liver disease patients (155 virus-related liver disease patients and 35 nonviral disease patients). The infection rates of the viruses among the 213 healthy subjects were as follows: 8% for HBV (16 patients), 2% for HCV (4 patients), and 8% for GBV-C/HGV (17 patients). In contrast, for 155 patients with acute hepatitis, chronic hepatitis, liver cirrhosis, or hepatocellular carcinoma, the infection rates were 30% for HBV (46 patients), 27% for HCV (41 patients), and 11% for GBV-C/HGV (17 patients). In the nonviral liver disease group of 35 patients with alcoholic liver disease, fatty liver, liver abscess, and biliary disease, the infection rates were 6% for HBV (2 patients), 20% for HCV (7 patients), and 26% for GBV-C/HGV (9 patients). The most common viral genotypes were type C of HBV (77%), type 3b of HCV (67%), and type 2 of GBV-C/HGV (67%). Moreover, testing for HEV among 371 subjects resulted in the detection of anti-HEV immunoglobulin G (IgG) in 117 patients (32%). The age prevalence of anti-HEV IgG was 3% for patients younger than 20 years and 30% or more for patients 20 years of age or older. Furthermore, a high prevalence of anti-HEV IgG (24%) was also found in swine living together with humans in Yangon. These results suggest that these hepatitis virus infections are widespread in Myanmar and have led to a high incidence of acute and chronic liver disease patients in the region.

A total of 47 patients with toxoplasmosis (21 cases) with amoebic liver abscess (14 cases) and with giardiasis (12 cases) as well as 14 healthy control were subjected to thorough history taking, clinical examination, stool & urine analysis, complete blood picture, ESR, C-reactive protein, ASO, widal test, blood cultures, liver function tests, serum creatinine, hepatitis viral markers, rheumatoid factor, auto-antibodies, stool culture, rectal snip, chest X-ray, abdominal sonar, level of serum adhesion molecules (sICAM-1, sELAM-1), ELISA detection of Toxoplasma antibodies in serum, liver biopsy, detection and counting of Giardia cysts. In toxoplasmosis group, highly significant increase in serum levels of sICAM-1 (P<0.01) and significant increase in serum levels of sELAM-1 (P<0.05) in comparison to control. However, only sICAM-1 levels were significantly increased in IgM cases more than in IgG cases. In amoebic liver abscess group, both sICAM-1 and sELAM-1 significantly increased when compared with control. In giardiasis group, highly significant increase of serum levels of sELAM-1 was noticed than in control group (P<0.01), while sICAM-1 showed no significant difference (P>0.05). There was no correlation between sELAM-1 and number of cysts in the stool (intensity of infection). Soluble forms of adhesion molecules especially sICAM-1 have the potentiality as good markers of endothelial damage, severity of disease and to less extend load of infection.

Cellulose acetate precipitation (CAP) test for the detection of antibody against Entamoeba histolytica using the axenic antigen, was performed on the 127 serum samples obtained from patients with amoebic liver abscess (14), amoebic hepatitis (21), amoebic dysentry (11), amoebic colitis (31), other parasitic infestations (25) and normal individuals (25). The percent positivity was 100, 95.23, 90.9, 67.74 and 16 and 12 respectively whereas the corresponding figures for the indirect immunoflourescence (IFAT) test were 100, 100, 100, 74.19, 12 and 8 respectively. Although CAP is not as good a test as IFAT, yet it can be recommended for routine testing due to its sensitivity, speed of performance and applicability to a single serum sample.

From January 1990 to December 2000, 202 patients with clinical evidence of liver disease underwent fine needle aspiration cytology of the liver. Of these, 102 patients were diagnosed as non-neoplastic lesions. These include diffuse parenchymal disease of liver, liver abscess, hepatitis, and granulomas. There were 100 patients with malignancies of the liver. Out of the above, 64 were due to metastatic carcinoma, 31 were primary hepatocellular carcinoma, 1 hepatoblastoma and in 4 patients the diagnosis of non-Hodgkin's lymphoma was made. By comparing with clinical and biochemical parameters, the diagnostic accuracy of the fine needle aspiration cytology, in this study, was found to be more accurate in malignant nodules of the liver as compared to other pathological lesion. The findings of fine needle aspiration cytology of the liver reported by other authors are discussed and it is concluded that this diagnostic method is a safe, useful and economic procedure with minimum complication and can be routinely done for assisting diagnosis of liver diseases in our clinical set up.

Clinical features of liver involvement due to Listeria monocytogenes infection in adults are rarely reported in literature. This is surprising, regarding the current opinion that the portal system is extensively involved in the first stages of pathogenesis in invasive L. monocytogenes disease. A literature search in the PubMed and Embase database revealed 34 cases with clinical features of hepatic involvement due to listeriosis. We systematically analyzed all case reports with respect to clinical manifestations, treatment and outcome. In addition, we added clinical information on a patient diagnosed with a solitary liver abscess due to L. monocytogenes, who was seen at our institution. This review describes the different presentations of liver-involvement reported in listeriosis; solitary liver abscess, multiple liver abscesses and diffuse or granulomatous hepatitis. Distinction between these different forms of liver involvement is clinically relevant as they have a different outcome. We delve into the different pathogenic events leading to different forms of liver involvement. In addition, diagnostic modalities and possible treatments are reviewed.

Cryptococcus neoformans usually involves the central nervous system and the respiratory tract. We report a case of disseminated cryptococcosis with a liver abscess and meningoencephalitis in a patient with myelodysplastic syndrome. Computed tomography of the abdomen showed a 3-cm low-attenuated lesion in the left lobe of liver. Cultures from specimens of blood, the liver abscess, and the cerebrospinal fluid all yielded C. neoformans. The cryptococcal antigen titers for the serum and cerebral fluid were both 1:32. The patient was successfully treated with 1,335 mg of amphotericin-B followed by fluconazole. Most cryptococcal liver infections present as hepatitis, cholangitis, or microabscesses.

An 80-year-old woman with hilar cholangiocarcinoma was hospitalized due to sudden-onset abdominal pain. Computed tomography revealed hepatic necrosis accompanied with emphysematous change in the superior segment of the right liver (S7/S8), implying spontaneous rupture, based on the presence of perihepatic free air. Although urgent percutaneous drainage was performed, neither pus nor fluids were drained. These findings suggest emphysematous hepatitis with a hepatic mass. Despite the application of intensive care, the patient's condition deteriorated rapidly, and she died 3 days after admission to hospital. Liver gas has been reported in some clinical diseases (e.g., liver abscess) to be caused by gas-forming organisms; however, emphysematous hepatitis simulating emphysematous pyelonephritis is very rare. The case reported here was of fatal emphysematous hepatitis in a patient with hilar cholangiocarcinoma.

Tuberculosis is one of the most common diseases in India and has attained epidemic proportions. Tuberculosis and liver are related in many ways. Liver disease can occur due to hepatic tuberculosis or the treatment with various anti-tubercular drugs may precipitate hepatic injury or patients with chronic liver disease may develop tuberculosis and pose special management problems. Tuberculosis per se can affect liver in three forms. The most common form is the diffuse hepatic involvement, seen along with pulmonary or miliary tuberculosis. The second is granulomatous hepatitis and the third, much rarer form presents as focal/local tuberculoma or abscess. Tubercular disease of liver occurring along with pulmonary involvement as in disseminated tuberculosis is treated with standard regimen for pulmonary tuberculosis. Granulomatous hepatitis and tubercular liver abscess are treated like any other extra-pulmonary tubercular lesions without any extra risk of hepatotoxicity by anti-tubercular drugs. Treatment of tuberculosis in patients who already have a chronic liver disease poses various clinical challenges. There is an increased risk of drug induced hepatitis in these patients and its implications are potentially more serious in these patients as their hepatic reserve is already depleted. However, hepatotoxic anti-tubercular drugs can be safely used in these patients if the number of drugs used is adjusted appropriately. Thus, the main principle is to closely monitor the patient for signs of worsening liver disease and to reduce the number of hepatotoxic drugs in the anti-tubercular regimen according to the severity of underlying liver disease.

Serum alkaline phosphatase (ALP) (EC 3.1.3.1), 5'nucleotidase (5'NT) (EC 3.1.3.5), aldolase (ALD) (EC 4.1.2.13) and sorbitol dehydrogenase (SDH) (EC 1.1.1.14) were estimated in infective hepatitis, alcoholic hepatitis, chronic active hepatitis, obstructive jaundice, cirrhosis of liver and amoebic liver abscess. It was observed that serum ALP and 5'NT were significantly increased in all cases of chronic active hepatitis and obstructive hepatic disease. However, the elevation observed in the latter was much higher than the former. Serum SDH and ALD levels were elevated in all cases of infective hepatitis, studied though increase in the former was much higher than the latter, suggesting its significance in the diagnostic confirmation of this disease. Results presented suggest 5'NT and SDH as more reliable diagnostic test compared to ALP and ALD for obstructive jaundice and infective hepatitis respectively.

Abnormal liver biochemical tests are present in up to 30% of patients with inflammatory bowel disease (IBD), and therefore become a diagnostic challenge. Liver and biliary tract diseases are common extraintestinal manifestations for both Crohn's disease and ulcerative colitis (UC), and typically do not correlate with intestinal activity. Primary sclerosing cholangitis (PSC) is the most common hepatobiliary manifestation of IBD, and is more prevalent in UC. Approximately 5% of patients with UC develop PSC, with the prevalence reaching up to 90%. Cholangiocarcinoma and colon cancer risks are increased in these patients. Less common disorders include autoimmune hepatitis/PSC overlap syndrome, IgG4-associated cholangiopathy, primary biliary cirrhosis, hepatic amyloidosis, granulomatous hepatitis, cholelithiasis, portal vein thrombosis, liver abscess, and non-alcoholic fatty liver disease. Hepatitis B reactivation during immunosuppressive therapy is a major concern, with screening and vaccination being recommended in serologically negative cases for patients with IBD. Reactivation prophylaxis with entecavir or tenofovir for 6 to 12 mo after the end of immunosuppressive therapy is mandatory in patients showing as hepatitis B surface antigen (HBsAg) positive, independently from viral load. HBsAg negative and anti-HBc positive patients, with or without anti-HBs, should be closely monitored, measuring alanine aminotransferase and hepatitis B virus DNA within 12 mo after the end of therapy, and should be treated if the viral load increases. On the other hand, immunosuppressive therapy does not seem to promote reactivation of hepatitis C, and hepatitis C antiviral treatment does not influence IBD natural history either. Most of the drugs used for IBD treatment may induce hepatotoxicity, although the incidence of serious adverse events is low. Abnormalities in liver biochemical tests associated with aminosalicylates are uncommon and are usually not clinically relevant. Methotrexate-related hepatotoxicity has been described in 14% of patients with IBD, in a dose-dependent manner. Liver biopsy is not routinely recommended. Biologics-related hepatotoxicity is rare, but has been shown most frequently in patients treated with infliximab. Thiopurines have been associated with veno-occlusive disease, regenerative nodular hyperplasia, and liver peliosis. Routine liver biochemical tests are recommended, especially during the first month of treatment. All these conditions should be considered in IBD patients with clinical or biochemical features suggestive of hepatobiliary involvement. Diagnosis and management of these disorders usually involve hepatologists and gastroenterologists due to its complexity.
