A Superinfection of Salmonella typhi and Hepatitis E Virus Causes Biphasic Acute Hepatitis.

A 47-year-old Japanese man was referred to our hospital because of a sustained high fever with diarrhea 12 days after a flight from India. Liver enzymes were elevated with rose spots, hepatosplenomegaly, relative bradycardia, and acute cholecystitis. A liver biopsy depicted the dense infiltration of lymphocytes and Kupffer cells in sinusoids and the granulomatous formation in the parenchyma. The liver damage was initially resolved with the administration of ceftriaxone for 16 days but flared up 1 week later. Laboratory tests yielded positive reactions for Salmonella typhi and hepatitis E virus RNA. The pathophysiological presentations of concurrent typhoid and type E hepatitis are discussed.

Salmonella hepatitis: an uncommon complication of a common disease.

Typhoid fever is a very common infectious disease of tropics, associated with high morbidity and mortality. Typhoid fever is often associated with hepatomegaly and mildly deranged liver functions; a clinical picture of acute hepatitis is a rare complication. We report a young patient who presented with fever and jaundice and was found to have acute hepatitis secondary to typhoid fever. Recognition of Salmonella hepatitis is of clinical importance as it can mimic acute viral hepatitis. Early institution of specific therapy can improve the prognosis in these patients.

Typhoid Fever Complicated by Intussusception, Splenic Infarction, and Hepatitis

Salmonella typhi infections usually manifest with high fever and gastrointestinal symptoms, however, occurrence of severe complications in other organs, such as pneumonitis, bronchitis, hepatitis, nephritis, encephalitis, and osteomyelitis, is possible. Although common surgical complications include ileal perforation and gastrointestinal haemorrhage, few cases of intussusception have been reported. Splenic infarction is another uncommon complication. In this report, we present a case of typhoid fever complicated with simultaneous small bowel intussusception and splenic infarction. A 27-year-old male patient with no previous history of interest underwent examination for fever, acute abdominal pain, and watery diarrhea of seven days duration. Findings on the initial examination indicated fever of 39.1degrees C, a distended abdomen with direct and rebound tenderness of diffuse localization, and rigidity. Abdominal computed tomography showed hepatomegaly, multiple lymphadenopathies, multiple segmental splenic infarctions, and small bowel ileus with intussusception, however, findings from the small bowel enema study showed spontaneous resolution of the intussusception. Despite antibiotic therapy, abdominal symptoms continued, therefore, the patient underwent exploratory laparotomy with suspicion of intestinal perforation. Surgical findings included multiple enlarged lymphadenopathies and coarse appearance of the liver, but no perforation was found. Results of the Widal test showed positivity for flagellar (H), somatic (O) and A antigens (1:640 dilutions each). Blood cultures showed Salmonella typhi. lymph nodes and biopsy showed mesenteric lymphadenitis, with enlarged lymph nodes due to distension of the sinusoids by macrophages, which showed erythrophagocytosis and tingible bodies. In addition, liver biopsy showed a granulomatous aggregate comprised of macrophages with an epithelioid configuration. After intravenous administration of antibiotics, the patient showed progressive improvement and was discharged for outpatient department follow up.
