A case of hemophagocytic syndrome in a patient with fulminant ulcerative colitis superinfected by cytomegalovirus

Hemophagocytic syndrome (HPS) is an uncommon hematological disorder that manifests as fever, splenomegaly, and jaundice, with hemophagocytosis in the bone marrow and other tissues pathologically. Secondary HPS is associated with malignancy and infection, especially viral infection. The prevalence of cytomegalovirus (CMV) infection in ulcerative colitis (UC) patients is approximately 16%. Nevertheless, HPS in UC superinfected by CMV is very rare. A 52-year-old female visited the hospital complaining of abdominal pain and hematochezia for 6 days. She was diagnosed with UC 3 years earlier and had been treated with sulfasalazine, but had stopped her medication 4 months earlier. On admission, her spleen was enlarged. The peripheral blood count revealed pancytopenia and bone marrow aspiration smears showed hemophagocytosis. Viral studies revealed CMV infection. She was treated successfully with ganciclovir. We report this case with a review of the related literature.

Staphylococcus warneri meningitis in a patient with Strongyloides stercoralis hyperinfection and lymphoma: first report of a case / Staphylococcus warneri meningite em paciente com hiperinfecção com Strongyloides stercoralis e linfoma: primeiro relato de caso

A case of meningitis due to Staphylococcus warneri in a patient with a hyperinfection with Strongyloides stercoralis possibly associated with rituximab treatment for mantel cell lymphoma is reported for the first time in the literature. The patient was a 59-year-old woman, with a 3-year history of an apparently well controlled lymphoma after treatment with chemotherapy-immunotherapy and then immunotherapy alone, and diagnosis of strongyloidiasis. Meningitis was diagnosed by cerebrospinal fluid culture and tested with an automated plate system. The patient was successfully treated with vancomycin; although fever and productive cough persisted. Severe gastrointestinal symptoms and pneumonia developed three weeks later. Hyperinfection syndrome by S. stercoralis was diagnosed, with abundant larvae in feces and expectoration.

Caso de meningite por Staphylococcus warneri em paciente com hiperinfecção com Strongyloides stercoralis, possivelmente associada com tratamento de rituximab para linfoma de células do manto é relatada pela primeira vez na literatura. A paciente, mulher de 59 anos com história de três anos de linfoma aparentemente bem controlado com tratamento com quimioterapia-imunoterapia e, em seguida, somente imunoterapia e diagnóstico de estrongiloidíase. Meningite foi diagnosticada por cultura do líquido cefalorraquidiano e testada com sistema automatizado de placa. A paciente foi tratada com sucesso com vancomicina, embora a febre e a tosse produtiva não tenham desaparecido. Após graves sintomas gastrointestinais a paciente desenvolveu pneumonia três semanas mais tarde. Síndrome de hiperinfecção por S. stercoralis foi diagnosticada, com larvas abundantes nas fezes e expectoração.

Hepatitis E virus infection in chronic liver disease causes rapid decompensation.

Hepatitis E previously known as enterically transmitted non-A, non-B hepatitis, is a self limiting infectious viral disease of developing countries. Various issues regarding the pathogenesis of liver injury and its natural history remain unanswered after two decades of its discovery. A small proportion of patients develop fulminant hepatic failure. Mortality is very high if it is associated with pregnancy, especially during third trimester. After establishment of hepatitis A virus as a cause of decompensation of chronic liver disease, now there are reports that hepatitis E viruses also does the same. Acute hepatitis E in these patients has a protracted course with high morbidity and mortality. Many patients develop hepatorenal syndrome, hepatic encephalopathy and even liver failure after co-infection with hepatitis E virus. Now time has come to institute hepatitis E virus superinfection as one of the cause of acute on chronic liver failure. Hepatitis E is a problem of developing countries and Nepal is in the endemic zone. Sudden decompensation in chronic liver disease patient, who were otherwise stable and under regular follow up, should be carefully dealt with. Patient statistics at our unit shows that 7 cases of chronic liver diseases with superinfection with hepatitis E virus were dealt from April 2004 to August 2005. Two patients (29%) died and 5 recovered. In patients with recovery, there was deterioration of Child-Pugh grading and the duration of hospital stay was longer. Thus, hepatitis E in diagnosed chronic liver disease case should be taken apprehensively. Similarly patients of chronic liver disease traveling to endemic zone should take precaution. If vaccine against hepatitis E virus is developed, chronic liver disease patient would be the eligible candidate for vaccination beside pregnant ladies.

Superimposed acute hepatitis E infection in patients with chronic liver disease.

BACKGROUND: The natural history of infection with hepatitis E virus (HEV) in patients with chronic liver disease (CLD) is not well described. Our study aims to document the presentation, course and outcome of HEV superinfection in patients with CLD. METHODS: Over an 18-month period, ten patients with CLD were diagnosed to have HEV superinfection by detection of anti-HEV IgM antibodies in a setting of acute worsening. These patients were tested for HBsAg, IgM anti-HBc, anti-hepatitis C virus antibodies and IgM anti-hepatitis A virus antibodies, and were followed-up. RESULTS: The etiology of underlying CLD in the 10 patients (9 men; mean [SD] age 42.4 [10.3] years) was alcohol in five patients, hepatitis B in two, hepatitis C in one and cryptogenic in two. Seven patients presented for the first time with recent-onset liver decompensation (median duration 27 days, range 7-45). All 10 had ascites and 7 had hepatic encephalopathy. Four patients developed renal failure during the course of illness. The median (range) bilirubin, ALT and albumin levels at presentation were 18.6 (4.9-32.6) mg/dL, 105 (28-6610) IU/L and 32 (29-41) g/L, respectively. At 8 weeks, only one patient had normalization of serum bilirubin or ALT levels. Three patients (30%) died, including two of renal failure and one of massive upper GI bleed. CONCLUSIONS: Superinfection with HEV in patients with CLD causes severe liver decompensation, which is frequently complicated with hepatic encephalopathy and renal failure. Acute hepatitis E in these patients has a protracted course with high morbidity and mortality.
