[Fungal infections in granulocytopenic and immunocompromised patients].
Opportunistic fungus infections in neutropenic immunocompromised patients have strikingly increased, especially with the improvement of antibiotic treatment. Their outcome is often fatal because of the difficulties in diagnosis and treatment. Therefore a rationale of surveillance diagnostics and empiric treatment in risk patients is necessary. In these patients a continuous weekly mycotic diagnosis of mouth, throat, faeces, urine, vagina, as well as of the blood is necessary. During an aggressive neutropenia-producing chemotherapy an antimycotic prophylaxis with the aim of reducing fungal colonization in the gastrointestinal tract (sometimes in the respiratory pathways, too) should be performed. Fever of unknown origin lasting longer than 4-5 days in spite of broad spectrum antibiotic treatment and/or positive diagnostic findings must lead to treating risk patients empirically using amphotericin B 1 mg/kg/d or a combination of amphotericin B 0.3-0.5 mg/kg/d together with flucytosin (Ancotil) 150 mg/kg/d. In case of a beginning candidiasis, patients can first be treated with fluconazol (Diflucan). The dose is 400 mg/d, later on 200 mg/d. It is pointed out that, much more often than usual, in risk patients with fever, atypical pneumonia, meningoencephalitis or other organ symptoms fungal infections should be taken into consideration. The most common opportunistic fungal diseases are presented and details concerning the different antimycotic drugs are given.
