The Spectrum of Hepatic Injury in Enteric Fever

Thirty six patients with culture-proven enteric fever and 15 patients of fever with etiology other than enteric fever as a control group were studied, with special reference to hepatic dysfunction and its relation to clinical features of the disease. Hepatomegaly was observed in 55% of enteric fever patients, and was slightly more common than splenomegaly (50%). Its incidence in typhoid fever (67%) was three times higher than in paratyphoid fever (22%). Hepatic dysfunction occurred in 55% of cases. Jaundice was noted in only 8% of the cases, whereas hyperbilirubinemia (serum bilirubin greater than 1.8 mg %) was present in 17%. Although hepatic manifestations of enteric fever were mild, a small but important group had sufficient hepatic involvement to mimick the clinical picture seen in viral hepatitis, amebic liver disease, and malaria with jaundice. It may be considered of clinical significance, since enteric hepatitis responds very well to specific therapy.     

Hepatitis A,cardiomyopathy, aplastic anemia,and acute liver failure: A devastating scenario

Hepatitis A virus (HAV) causes an acute infection and is usually asymptomatic in children. When clinical manifestations appear, these include choluria, jaundice, and abdominal pain. Although infrequent, extra‐hepatic manifestations related to HAV have been described, affecting the heart, bone marrow, blood vessels, and other tissues.A 10‐year‐old boy from a rural area presented with a 15‐day history of malaise, fever, and jaundice; laboratory examinations were compatible with HAV infection. The patient turned encephalopathic and was remitted to our center, where laboratory examinations showed a medullary aplasia and fulminant hepatitis requiring a liver transplant that was performed 72 hours after admission. At 24 hours post transplant, the patient developed a cardiomyopathy secondary to HAV, and intravenous immunoglobulin was administered. The patient is still alive and attending his medical check‐ups.Although rare, extra‐hepatic manifestations of HAV infection have been described in 14% of cases. The groups of patients affected are usually aged and present with high bilirubin levels. Acquired aplastic anemia and myocarditis caused by HAV are uncommon, and its pathophysiology has not yet been elucidated.HAV infection is usually asymptomatic in children, although extra‐hepatic manifestations can appear requiring early detection and management.     

Salmonella Paratyphi A liver abscess—Secondary infection of an amoebic liver abscess?

Liver abscess is a rare complication of both enteric fever and non-enteric salmonella infection. We present an unusual case of Salmonella Paratyphi A liver abscess, where secondary bacterial infection of an amoebic liver abscess was suspected.     

Hepatobiliary system in sickle cell disease

This paper reviews the literature reports concerning sickle cell disease and the hepatobiliary system. Sickle cell disease can cause progressive injury to the liver with significant fibrosis, often cirrhosis, and decreased liver function by adulthood. Asymptomatic patients commonly have hepatomegaly and elevated liver enzyme levels. The presence of sickle cell disease obscures features otherwise useful in differential diagnosis. Acute episodes of the disease selectively affect the liver in 10% of patients, causing hepatic crisis with abdominal pain, nausea, fever, jaundice, and transaminase elevation. Viral hepatitis is often clinically indistinguishable from hepatic crisis, but in viral hepatitis the abdominal pain is usually less, the jaundice tends to be more severe, and the transaminase elevation more prolonged. The two can be distinguished by serology and liver biopsy. Furthermore, acute cholecystitis or choledocholithiasis may have clinical and laboratory features similar to sickle cell hepatic crisis or viral hepatitis. By adulthood, 50%-70% of sickle cell patients have gallstones. Elective cholecystectomy is indicated for those who are symptomatic, but, because of operative mortality, there is disagreement concerning surgery for asymptomatic patients. The literature contains nine well-documented cases of acute hepatic failure related to sickle cell disease. The mechanism is unclear; however, as the necrosis is often not severe, a metabolic problem is suggested.     

Case Report: Severe cholestatic jaundice induced by Epstein-Barr virus infection in the elderly

Infectious mononucleosis due to Epstein-Barr virus (EBV) is almost always a self-limited disease, most commonly seen in young adults. Hepatitis is a well-recognized complication of EBV infection that usually resolves spontaneously. Jaundice occasionally results from the unusual complication of autoimmune haemolytic anaemia rather than hepatitis. We report a 60-year-old man with severe cholestatic jaundice whose history, liver histology and laboratory findings suggested EBV infection. He also developed significant jaundice related to his hepatitis, but not to autoimmune haemolysis, a situation that led to diagnostic delay. Costly diagnostic laboratory tests and invasive procedures were performed to rule out a malignant extrahepatic biliary obstruction. Physicians need to be aware of this complication and EBV infection should be included in the differential diagnosis of cholestatic jaundice in the elderly.     

Jaundice and the sulfonamide drugs

It is apparent from a review of the reported cases of hepatitis associated withsulfonamide therapy that it is usually possible to recognize this toxic manifestation. This is of considerable practical importance since, in every instance in whichthe sulfonamide is responsible for the jaundice, treatment with the drug should bediscontinued and some other form of therapy, such as the antibiotics, instituted.If the jaundice is not secondary to the sulfonamide, therapy may be continued evenin the presence of hepatitis secondary to the infection.

Jaundice which appears during the first week of chemotherapy is usually associated with a previous history of ingestion of sulfonamides and accompanyingsigns of toxicity (immediate sulfonamide jaundice) or with acute hemolyticanemia and jaundice (intermediate jaundice). In either instance the diagnosis is notdifficult because the clinical and laboratory abnormalities are characteristic.Finally, jaundice which occurs after ten days of chemotherapy is usually associatedwith other toxic manifestations, especially fever and various forms of rashes(delayed jaundice). Occasionally jaundice may be the only toxic manifestation ofsulfonamide therapy and, in such patients, a definite diagnosis may be difficult.

     

Enteric Fever

The records of 104 patients with culture-proven enteric fever were reviewed and evaluated as to the clinical signs, laboratory findings, pathologic features and complications of the disease. One patient with fatal disseminated intravascular coagulation and enteric fever is also presented. Fever and bradycardia were the leading clinical signs followed by splenomegaly, hepatomegaly and rose spots. The principal complications of enteric fever included anemia, typhoid hepatitis, relapse and bleeding. Evidence of typhoid hepatitis was present in 30% of the patients tested. The pathology consisted of typhoid nodules of variable frequency and size depending upon the severity of the condition. The relationship of typhoid hepatitis to relapse seems to be more than coincidental as four out of seven patients who had relapse had abnormal liver tests. The occurrence of disseminated intravascular coagulation in enteric fever is rare; however, awareness of such a potential complication may be life-saving to the patient.

The liver in heart failure

Severe congestive heart failure is associated with two distinct forms of liver dysfunction: jaundice that is related to passive congestion and acute hepatocellular necrosis that is caused by impaired perfusion. Cardiac cirrhosis (fibrosis) may result from prolonged recurrent congestive heart failure. Ischemic hepatitis (shock liver) usually manifests as asymptomatic elevation of the serum aminotransferase levels after an episode of hypotension, although the clinical presentation may mimic that of acute viral hepatitis. In most cases, ischemic hepatitis is of little clinical consequence and is self-limited. Acute liver failure may occur in patients with preexisting cirrhosis, severe chronic heart failure, or sustained hepatic ischemia.     

Acute hepatic failure due to hepatosplenic B-cell non-Hodgkin's lymphoma in a patient infected with hepatitis C virus

We report a 75-year-old Japanese man infected with hepatitis C virus (HCV) who died of acute hepatic failure due to the hepatic infiltration of B-cell non-Hodgkin's lymphoma (NHL) cells. He suddenly developed jaundice, fatigue, fever, and hepatosplenomegaly during the course of chronic infection with HCV. Postmortem liver necropsy revealed extensive infiltration of lymphoma cells into the liver. Although the association between HCV infection and NHL has recently become a matter of concern, we believe this to be the first reported case of acute hepatic failure caused by hepatic involvement of non-Hodgkin's lymphoma in an HCV-infected patient.

Listeria monocytogenes-associated acute hepatitis in a liver transplant recipient

ABSTRACT— We report a case of Listeria monocytogenes bacteriemia with liver involvement mimicking acute viral hepatitis in a liver transplant recipient. The patient presented with fever, jaundice and alanine aminotransferase levels ten times the upper limit of normal. Liver biopsy showed signs of acute hepatitis and occasional granulomas. Both blood and liver biopsy cultures were positive for Listeria monocytogenes. The patient received a 3 week course of ampicillin and gentamicin with clinical and biochemical recovery. Liver involvement during Listeria infections is unusual, and most cases occur in patients with underlying hepatic disease and impaired cell-mediated immunity. To our knowledge only one such case has previously been reported in a liver transplant patient. Furthermore, in the present case we isolated the causal agent from the liver biopsy specimen.     

Concurrent salmonella bacteremia in P. vivax infection--a report of 2 cases at the Hospital for Tropical Diseases, Thailand

Malaria and concurrent bacteremia has been described in many reports, most of them with P. falciparum. Concurrent bacteremia with P. vivax infected patients is very rare. We reported 2 cases of salmonella bacteremia with P. vivax infection. Both patients presented with fever and the diagnosis of P. vivax was confirmed microscopically. The first patient presented with fever, jaundice, shock and renal failure which rarely occurs with P. vivax infection. The second patient had no clinical response after receiving standard antimalarial drugs. Hemoculture was positive for Salmonella spp in both cases. They recovered completely after appropriate antibiotics and antimalarial treatment.     

Sjögren's syndrome associated with autoimmune hepatitis. A case report

Summary Liver involvement in patients with primary Sjögren's syndrome is rare, usually without clinical significance and histologically characterized by a feature like stage 1 primary biliary cirrhosis. We describe herein a case of acute and severe autoimmune hepatitis in a patient suffering from primary Sjögren's syndrome. The diagnosis of Sjögren's syndrome was performed in 1989.In June 1995 the patient presented severe weakness, jaundice and elevation of transaminases; moreover IgG raised to 5560 mg/dl and ANA titre increased to 1:20480. The patient denied alcohol and drug use and a viral hepatitis was excluded. Antimitochondrial antibodies, anti-smooth muscle antibodies and antibodies against liver kidney microsomes were negative. An abdomen ultrasound examination revealed hepatomegaly, with irregular echogenic structure and lymphoadenomegaly near the celiac tripod. Liver biopsy demonstrated a picture of autoimmune hepatitis.The patient was treated with prednisone 50 mg/day and azathioprine 50 mg/day, with improvement in clinical and liver function indices. At present, the patient is given only 10 mg/day of prednisone.The association of Sjögren's syndrome with autoimmune hepatitis is very rare: in the literature only one other similar case has been reported.

Acute viral cholecystitis due to hepatitis A virus infection

Acute hepatitis A virus (HAV) infection is frequent in developing countries. Although some gallbladder abnormalities are defined during the course, an acute cholecystitis is extremely rare. We here report 2 additional cases of cholecystitis due to acute HAV infection and review the previously reported 2 cases. One of our patients was admitted with jaundice and a suspicious portal mass with a presumed diagnosis of cholagiocarcinoma. The other presented with jaundice, abdominal pain, and constitutional symptoms. Both patients were planned to be operated on. During the follow-up, absence of fever, leukocytosis, acute-phase protein response, and calculus in biliary system were against the diagnosis of a bacterial cholecystitis. Moreover the course of cholecystitis was closely parallel to that of the HAV infection. Both patients were managed conservatively. It was concluded that rare, acute viral cholecystitis can develop during the course of acute HAV infection.     

Acute hepatitis C among renal failure patients on chronic haemodialysis

Hepatitis C virus (HCV) infection is common in haemodialysis units, yet little information is available about the clinical feature of acute hepatitis C among renal failure patients. The present study is based on 49 cases of acute hepatitis C seen at a haemodialysis centre where sporadic nosocomial infection was occurring up to June 1993. Liver function tests were done at 4 weekly intervals on all dialysis patients, anti-HCV antibodies were tested by the C-100 and second generation tests and serum HCV-RNA was determined by the branched DNA and Amplicore tests. Diagnosis of acute hepatitis C was made on the basis of an acute rise in alanine aminotransferase (ALT) and seroconversion to positive anti-HCV antibodies. Clinical presentation of acute hepatitis was generally mild with rare overt jaundice and the diagnosis was possible only from increased ALT, which was generally low. Spontaneous resolution of acute hepatitis within 8 months with clearance of viral RNA occurred in only four cases, 91.8% of patients developing chronic hepatitis. Biopsy in 12 cases with high ALT levels showed mild to moderate inflammatory activities. In conclusion, the clinical presentation of acute hepatitis C is generally mild in chronic haemodialysis patients, but spontaneous resolution is infrequent. A longer follow-up period is required for defining the long-term prognosis.     

Subacute fulminant hepatic failure with intermittent fever

BACKGROUND:Viral hepatitis B accounts for over 80% of acute hepatic failures in China and the patients die mainly of its complications.A patient with hepatic failure and fever is not uncommon,whereas repeated fever is rare.METHODS:A 32-year-old female was diagnosed with subacute hepatic failure and hepatitis B viral infection because of hyperbilirubinemia,coagulopathy,hepatic encephalopathy,serum anti-HBs-positive without hepatitis B vaccination,and typical intrahepatic pathological features of chronic hepa...     

Coincidence of Acute Brucella Hepatitis and Dengue Fever or Serologic Cross-reactivity?

Hepatic involvement in brucellosis is not uncommon since 10-20% of patient infected with brucella species can have abnormal liver function tests. The usual presentation of brucella hepatitis is in the form of chronic granulomatous hepatitis with mild to moderate elevation of liver enzymes, while acute hepatitis is rare. We report a young patient who presented with acute brucella-induced hepatitis and co-infection with dengue hemorrhagic virus resulting in severe elevation of liver enzymes and absence of granuloma on histology. His mother also simultaneously tested positive for both infections. The patient responded well to anti-brucella therapy with normalization of his liver profile. We discuss, herein, the hepatic involvement of these two infections and discuss the possible serological cross-reactivity between brucella and dengue fever virus.     

Acute pancreatitis in acute viral hepatitis

AIM： To elucidate the frequency and characteristics of pancreatic involvement in the course of acute （nonfulminant） viral hepatitis. METHODS： We prospectively assessed the pancreatic involvement in patients with acute viral hepatitis who presented with severe abdomimanl pain. RESULTS： We studied 124 patients with acute viral hepatitis, of whom 24 presented with severe abdominal pain. Seven patients （5.65%） were diagnosed to have acute pancreatitis. All were young males. Five patients had pancreatitis in the first week and two in the fourth week after the onset of jaundice. The pancreatitis was mild and all had uneventful recovery from both pancreatitis and hepatitis on conservative treatment. The etiology of pancreatitis was hepatitis E virus in 4, hepatitis A virus in 2, and hepatitis B virus in 1 patient. One patient had biliary sludge along with HEV infection. The abdominal pain of remaining seventeen patients was attributed to stretching of Glisson＇s capsule. CONCLUSION： Acute pancreatitis occurs in 5.65% of patients with acute viral hepatitis, it is mild and recovers with conservative management.     

Typhoid fever complicated by multiple organ involvement: report of two cases

Typhoid fever complicated by multiple organ involvement has been rarely mentioned in the literature. We reported two cases of typhoid fever with several unusual manifestations, including acute renal failure, acute hepatitis, acute pancreatitis, disseminated intravascular coagulation, and lower gastrointestinal bleeding. A renal biopsy in the first case showed no pathological change. Bone marrow biopsy showed focal necrosis of matrix, which might have been due to severe illness. A liver biopsy in the second case showed a predominantly histiocytic proliferation with occasional neutrophilic infiltration in the portal areas and hepatic sinusoids. Focal necrosis, bile duct injury, and multiple eosinophilic bodies were also noted. After appropriate antimicrobial therapy, both patients recovered without any sequelae. The potential of multiple organ involvement is highlighted in typhoid fever, which, on rare occasions, may occur simultaneously in the same patient.
