Lamivudine treatment failure in preventing fatal outcome of de novo severe acute hepatitis B in patients with haematological diseases.

BACKGROUND: Patients with malignant haematological diseases administered or no longer receiving immunosuppressive therapy are at high risk of reactivation or de novo hepatitis B infection and fulminant hepatitis. Despite promising results in the treatment of chronic hepatitis and its use in selected patients with acute hepatitis B, there is no consensus on lamivudine treatment in severe acute hepatitis portending a fatal clinical outcome. CASE REPORTS: Of the ten patients with malignant haematological disorders who became infected with the same strain of hepatitis B virus during hospitalisation in a haematology ward, five received lamivudine (and in some cases, ganciclovir and famciclovir). The other patients received only supportive therapy, since deteriorating clinical conditions hampered specific treatment efforts. Eight patients died from acute liver failure and one from a fatal course of the haematological disease; one had a favourable outcome from the therapy. There was no significant difference in terms of survival between the treated and untreated patients. CONCLUSIONS: Although lamivudine has proved promising in the therapy of chronic hepatitis B and of recurrent hepatitis after liver transplantation, its use in de novo severe acute hepatitis should be investigated further, particularly in immunocompromised patients.

Fatal outcome after ingestion of star fruit (Averrhoa carambola) in uremic patients.

Clinical outcome of dialysis patients after eating star fruit (Averrhoa carambola) varies, but it may be fatal. In the past 10 years, 20 such patients were treated in our hospital when they developed clinical symptoms after eating the fruit or drinking star fruit juice. Their initial presentations included sudden-onset limb numbness, muscle weakness, intractable hiccups, consciousness disturbance of various degrees, and seizure. No other major events that might be responsible for these symptoms could be identified. Eight patients died, including one patient with a serum creatinine level of 6.4 mg/dL who had not yet begun dialysis. The clinical manifestations of the survivors were similar to those who died except for consciousness disturbance and seizure. Death occurred within 5 days despite emergent hemodialysis and intensive medical care. The survivors' symptoms usually became less severe after supportive treatment, and these patients subsequently recovered without obvious sequelae. The purpose of this article is to report that patients with renal failure who ingest star fruit may develop neurological symptoms and also run the risk for death in severe cases. Mortality may also occur in patients with chronic renal failure not yet undergoing dialysis.

High numbers of granzyme B/CD8-positive tumour-infiltrating lymphocytes in nasopharyngeal carcinoma biopsies predict rapid fatal outcome in patients treated with curative intent.

This study determined whether tumour-infiltrating lymphocytes (TILs) in nasopharyngeal carcinomas (NPCs) include activated cytotoxic T lymphocytes (CTLs) and whether the numbers of activated CTLs in these biopsies are related to clinical outcome. Moreover, the study investigated whether the numbers of activated CTLs are associated with the expression of MHC class I proteins and the granzyme B antagonist PI-9 in the tumour cells. Forty-three Indonesian NPC patients (T(1-3), N(1-3), M(0)), who were treated with curative intent by radiotherapy only, were studied. Tumour-infiltrating activated CTLs were detected using antibodies against granzyme B, CD8, and CD56. Expression of MHC class I proteins and PI-9 was also determined by immunohistochemistry. Granzyme B-positive TILs were detected in all NPC biopsies. The presence of a high percentage (>25%) of granzyme B-positive TILs appeared to be a very strong predictor of a rapid fatal clinical outcome, independent of stage. Complete absence of MHC class I heavy chain expression in tumour cells was observed in 11 of 31 evaluable cases and low levels were observed in seven additional cases. No association between MHC class I expression and the numbers of granzyme B-positive TILs was observed. Expression of the granzyme B antagonist PI-9 in tumour cells was detected in three cases. It is concluded that the presence of many granzyme B-positive TILs in a selected group of Indonesian NPC patients is a strong and stage-independent marker for a rapid fatal clinical outcome.
