Infectious complications in 126 patients treated with high-dose chemotherapy and autologous peripheral blood stem cell transplantation.

The effect of an extensive prophylactic antimicrobial regimen was prospectively assessed in 126 patients after high-dose chemotherapy and autologous PBSC. They received ciprofloxacin (500 mg/12 h), acyclovir (200 mg/6 h), and itraconazole (200 mg/12 h) orally until neutrophil recovery. Febrile patients received i.

[Invasive pulmonary aspergillosis: a study of 33 cases].

Invasive pulmonary aspergillosis (IPA) is an infectious complication appearing mainly in immunosuppressed patients, whose diagnosis is often difficult and lately made, and that usually bears a dismal prognosis. Patients diagnosed as having IPA from 1989 to 1994 were retrospectively analyzed. Probable IPA was diagnosed on the basis of a positive culture for Aspergillus together with a consistent radiological image.

Epidemiologic evidence of transmission of donor-related bacterial infection through a transplanted heart.

This study describes a patient who had fulminant infectious myocarditis as a result of methicillin-resistant Staphylococcus aureus after receiving a heart transplant from an infected donor. There was complete concordance of typing results between donor and recipient strains that were different from the 20 isolates with which they were compared. Molecular epidemiologic study provided compelling evidence that a transplanted organ can transmit a bacterial infection from the donor to the recipient.

Epstein-Barr virus infection associated with interstitial nephritis and chronic fatigue.

Severe renal disease in the setting of Epstein-Barr virus (EBV) infection is exceedingly rare. We report here the case of a 22-year-old man with acute EBV infection associated with severe interstitial nephritis. The patient developed chronic fatigue and chronic renal failure with a serological profile typical of primary EBV infection.

[High-dosage chemotherapy and the autologous transplantation of peripheral hematopoietic progenitor cells in breast cancer: the initial results, analysis of toxicity and the necessary support means].

Background: In the last years high dose chemotherapy (HDC) schedules have been developed with autologous bone marrow transplantation (ABMT) which are very effective in breast cancer. Expectation has been raised concerning the cure of a subgroup of patients with metastatic breast cancer and the improvement of prognosis in high risk stages II and III.

Methods: CTCb (cyclophosphamide 6 g/m2, thiotepa 500 mg/m2 and carboplatin 800 mg/m2) was administered with autologous peripheral hematopoietic progenitor cells transplantation (TACPHP) and granulocytic colony stimulating factor (G-CSF) 5 micrograms/kg/day to 27 patients with breast cancer: 9 in stage IV in complete remission, 12 in stage II with > or = 10 affected lymph nodes and 6 in stage III.

[Blood donors seropositive for type 1 human immunodeficiency virus (HIV-1). Epidemiologic characteristics and clinical course].

Purposes: To evaluate retrospectively the epidemiologic profile and clinical course of the HIV-positive voluntary blood donors in the Sant Pau's Hospital Blood Bank (Barcelona-Spain) between 1986 and 1993.

Patients And Methods: A total of 119,345 blood donors were studied, and fifty seven such cases were identified. Risk behavior, causes of failure of the pre-donation procedures and clinical stage were analyzed.

[Reactive hemophagocytic syndrome: a probably underestimated cause of thrombocytopenia in intensive acre patients].

Thrombocytopenia is a common feature in ICU patients which occurs usually in case of infection or septic shock. Its mechanisms, which are often unclear, include the haemophagocytic syndrome initially linked with histiocytic proliferation but probably also associated with infectious diseases. This syndrome is characterized by a phagocytosis of medullar blood cells.

Use of restricted antibiotics in primary care.

The objective of this study was to detect and evaluate the use of restricted antibiotics (RAs) in our ambulatory care site. We retrospectively analyzed 1084 treatments of a selected group of intramuscularly administered antibiotics that are usually considered restricted for use in hospitals. Five cephalosporins, four aminoglycosides, and one acylureidopenicillin were analyzed.

Iatrogenic disseminated mycobacterium chelonei infection.

The case is presented of a patient who developed a disseminated infection caused by M. chelonei which arose from a fragment of intravascular polyethylene catheter that had been inserted six months earlier.
