Toxoplasma gondii infection in patients with hematological malignancies.

Toxoplasmosis is one of the most common parasitic infections in humans, but in most cases it does not cause serious illness; this protozoan can nevertheless cause devastating disease in immunocompromised hosts such as HIV-positive individuals. Only rarely is toxoplasmosis documented in hematological patients, and among them, those who undergo a transplant procedure are more frequently affected. In a retrospective multicenter survey, we collected data on six cases of toxoplasmosis in hematological patients. In the majority of cases, patients had undergone transplant procedures (five had undergone autologous or allogeneic transplantation). This complication needed special care in diagnosis, usually based on serology, neuroradiology, and PCR examination. However, in our experience the appropriate therapeutic approach was successful in the majority of cases

The association of topotecan and cytarabine in the treatment of secondary or relapsed acute myeloid leukemia

A topotecan/cytarabine combination has been reported to be effective in patients with myelodysplastic syndromes. We report our experience with this regimen in 12 patients with relapsed or secondary acute myeloid leukemia. Extra-hematologic toxicity was low, but the response to the treatment was very poor. In our opinion, this association is not a treatment option for these patients, but the addition of other agents could improve this results

Association between glutathione S-transferase genotypes and Hodgkin's lymphoma risk and prognosis

The interplay between genetic susceptibility and exposure to carcinogens has been shown to be involved in the etiology of many solid tumors. We studied the frequency and clinical correlates of polymorphisms resulting in deletions of two genes involved in the detoxification of potentially carcinogenic agents, glutathione S-transferase (GST)-M1 and GSTT1 in patients with Hodgkin's lymphoma (HL)
