"Ecstasy" (3,4-Methylenedioxymethamphetamine), is used as a mood enhancer. We describe a case of a 23 year-old male suffering from thrombotic thrombocytopenic purpura (TTP), and severe hepatitis following ingestion of ecstasy. We describe the various hepatic complications, including hepatitis, cirrhosis, and hepatic failure, in addition to the hematological complications including DIC and TTP secondary to ecstasy abuse. Ecstasy abuse should be considered in every patient with unexplained hepatic or hematologic complications.

110 drug addicted patients with infectious endocarditis (IE), 67 males and 43 females with average age 24 +/- 3.2 years were examined. Positive results of conservative therapy were in 69.2% patients with isolated lesion of tricuspid valve. Hospital lethality in the group of patients was 35.5% (39 cases). The analysis of survival rate of IE patients with the use of Cox's regression model made possible to establish that main predictors of lethal outcome in the group of patients were dimensions of microbe vegetations on tricuspid valve more than 2 cm, development of acute left ventricle failure, DIC-syndrome, and high degree tricuspid valve failure. Presence of HIV in early stage and C hepatitis without clinical laboratory activity did not have significant influence on IE outcome in this group of patients.

A 62-year female received radiotherapy over six weeks with daily 75 mg/m2 Temozolomide (TMZ) for Glioblastoma (GB). At the last week of radiotherapy, her liver enzymes and serum bilirubin started deteriorating. TMZ was discontinued. The histopathology demonstrated the features of acute cholestasis and focal parenchymal inflammation. A range of investigations failed to show any other contributory cause of hepatitis. She required in-hospital care for a prolonged period for a grade three hepatic failure. The liver functions very slowly recovered over 40 weeks, but her general condition continues to deteriorate. TMZ may cause a mild temporary rise in the liver enzymes and has been reported to reactivate hepatitis B. In few other cases concomitant medications were the possible causes of hepatitis. However, searching the Medline and other bibliographic database, we have not come across any case of TMZ-induced liver injury (TMZ-DILI). Histopathology and pattern of liver enzyme elevation suggest that unlike Dacarbazine, which causes veno-occlusive type liver damage, TMZ in this patient caused mainly cholestasis type liver injury. On Naranjo Adverse Drug Reaction (ADR) probability scale, this case falls in probable grade (Scale 7).

Ipilimumab (Yervoy) is a monocLonal antibody designed to block cytotoxic T cell antigen 4 (CTLA-4), an inhibitory receptor of T lymphocytes. This drug is the first to receive US FDAs approval for advanced stage malignant melanoma in the last 13 years. So far, no survival benefit was achieved for this patient group with single drug or combination chemo- and chemo-immunotherapy. In phase II and III trials, up to 15% of patients had melanoma regressions, with a decreased hazard ratio of death of 0.72 compared to the standard chemotherapy with Dacarbazine. The development of Ipilimumab marks a success in deciphering the check-point control on the immune response. Activated T cells over-express CTLA-4 molecule on their surface and become susceptible to its inhibitory effect. CTLA-4 decreases the signaling network derived by antigen recognition of T cells. Alongside of its therapeutic effect, the CTLA-4 blockade enhances autoimmune responses. Severe diarrhea results from toxicity to the colonic mucosa which may eventuate in perforation and, in rare cases, death. Other adverse events of varying severity occur in many patients and include skin eruption, uveitis, endocrinopathies such as thyroiditis and hypophysitis and autoimmune hepatitis. Ipilimumab toxicity is reversible with systemic use of corticosteroids, but the use of TNF inhibitors is sometimes indicated in the absence of resolution. The clinical success of the CTLA-4 blockade motivated intense searches for additional check-point modifiers, such as PD-1 molecule, with encouraging preliminary results. Ipilimumab's entry into the clinic is the opening of a new chapter in the immunotherapy of melanoma in particular, and of cancer, in general.

Treatment of advanced soft tissue sarcoma usually includes dacarbazine (DTIC), an alkylating agent that methylates DNA and is active during all phases of the cell cycle. Common side effects of DTIC include nausea, vomiting, impaired liver and kidney function, myelosuppression, and pneumonia. There are no accounts, however, of histological and hematological changes caused by DTIC. We investigated acute hematological and morphological changes in different organs and in tumors that were caused by a single dose of DTIC. Adult Syrian golden hamsters were inoculated with a suspension of tumorigenic baby hamster kidney (BHK) cells by subcutaneous injection. On day 14 after inoculation, doses of 1.4, 1.6, 1.8 or 2.0 g/m(2) DTIC were injected intraperitoneally into the hamsters. Hamsters in the control group were injected with physiological saline in the same way. Seven days after drug or saline injection the animals were sacrificed and samples of blood, heart, kidney, liver, lungs, spleen, small intestine and tumor were excised, processed and analyzed. Mitoses were counted using an ocular extension with engraved frame. Anemia, thrombocytopenia and leukocytosis were found in the control group of hamsters with fibrosarcoma, whereas animals with fibrosarcoma treated with DTIC developed anemia, thrombocytopenia and leukopenia. Severe pneumonia and moderate hepatitis were detected in all DTIC treated groups. Effects of DTIC on tumor cells included rounding and enlargement of nuclei and rarefaction of chromatin. The number of mitoses was reduced with increasing doses of DTIC. Hepatitis, myelosuppression, pneumonia, and dose-related inhibition of tumor cell proliferation were observed after a single dose of DTIC.
