Systemic Candida infections are a major cause of infectious morbidity and mortality during chemotherapy-induced
neutropenia
. Because of the unreliability of conventional diagnostic tests to detect systemic infection early in its course, treatment of established disseminated Candida infection has been generally disappointing with mortality rates of 60-80% in leukemia and bone marrow transplant patients and 30-40% in solid tumor patients. The use of empiric amphotericin B in patients with fever not responding to empiric antibacterial agents has been shown to be successful in reducing morbidity and mortality from fungal infections. However, its toxicity has mitigated the success of this approach.
Fluconazole
given prophylactically at the institution of chemotherapy has been shown to be a safe and effective alternative. It, however, is not active against all fungal species, especially Aspergillus and some of the less virulent Candida species. Some centers have reported break-through infections by these less susceptible organisms. Whether or not these limitations in its spectrum of activity will limit its usefulness in the future remains unanswered at this time and could pose a cloud to an otherwise bright promise.

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.

Neutropenia
induced by intensive chemotherapy and allogeneic bone marrow transplantation are increasingly commonly complicated by fungal infections; thus prophylaxis may be justified. The authors surveyed the literature and culled their experience - few randomized trials have been done and definitions have often been poor. In prophylaxis of mucosal candidosis, miconazole and clotrimazole may both be more effective than placebo. Nystatin is ineffective and ketoconazole of medicine efficacy.
Fluconazole
is effective at 50 mg/day and 400 mg/day. Itraconazole and amphotericin B both need further evaluation. In prevention of systemic candidosis, oral nystatin prophylaxis, up to 4 X 10(6) U/day, is usually unsuccessful, though compliance is variable. Oral amphotericin B in low doses is ineffective, but 50 mg or more 4 times daily may prevent systemic candidosis, though compliance is variable. Oral ketoconazole, 400-600 mg/day, is possibly effective prophylaxis in
neutropenia
but not after bone marrow transplantation; liver function (often abnormal in these patients) is a problem, as is tolerability. Oral fluconazole is well tolerated, has reliable serum concentrations and is effective following bone marrow transplantation, but the optimum dose is uncertain. In bone marrow transplantation, intravenous amphotericin B, 0.1 mg/kg/day, appears to be effective; there are no data in
neutropenia
. Oral itraconazole (capsules, 200 mg/day) may be active; data are scanty. In prevention of invasive aspergillosis, itraconazole, 200 mg/day, is probably active, but only if adequate serum concentrations are achieved. New oral and intravenous itraconazole formulations in cyclodextrin may achieve more reliable serum concentrations. No oral drug provides effective prophylaxis against Torulopsis, Fusarium, Trichosporon, or Pseudallescheria.

Hepatosplenic candidiasis has increased in frequency among immunocompromised hosts. Risk factors include hematologic malignancy, intensive chemotherapy, prolonged
neutropenia
, and treatment with broad-spectrum antibiotics. Patients most commonly present with abdominal pain, persistent fevers despite antibiotic therapy, and an elevated alkaline phosphatase level that is out of proportion to other hepatic enzyme levels. Gastrointestinal mucosal damage secondary to intensive chemotherapy may allow colonization with Candida species and subsequent seeding of the portal vein. Treatment has consisted of prolonged courses of amphotericin B, with mortality rates approaching 50%. We report a case of hepatosplenic candidiasis in a patient with acute myelogenous leukemia who had clinical and radiographic improvement during fluconazole therapy.
Fluconazole
may be an efficacious and less toxic alternative to amphotericin B.

Fluconazole
is a new orally absorbed antifungal azole which is effective in the treatment of mucosal and systemic infections caused by Candida, cryptococci and other fungi. In view of its favourable efficacy, safety and pharmacokinetic profile it was considered appropriate to evaluate its use prophylactically in patients undergoing a period of
neutropenia
. Two hundred and forty-eight patients receiving chemotherapy and/or bone marrow transplantation for the treatment of acute leukaemia, lymphoma or aplastic anaemia, and expected to be rendered temporarily neutropenic, have been entered into an ongoing multicentre comparative clinical study to compare the prophylactic efficacy of 50 mg daily oral fluconazole with that of widely used regimens of oral polyenes. The incidence of suspected fungal infection was less in the fluconazole group (27%) than in the polyene group (45%), the difference being statistically significant (P less than 0.05). Only one of the suspected infections in the fluconazole group was confirmed mycologically compared with 17 in the polyene group.
Fluconazole
prophylaxis was well tolerated and it therefore offers a promising new approach to the management of fungal infection in the neutropenic patient. Further studies are warranted to define the optimum dosage for use in this situation.

Fungal infections are a major problem in patients with hematologic malignancy. Attempts to reduce their frequency with antifungal agents have not been successful. A double-blind, controlled, single-center trial was conducted with 96 consecutive patients undergoing 154 episodes of chemotherapy. Patients received 400 mg of fluconazole or placebo until bone marrow recovery or initiation of intravenous amphotericin B infusions. End points were amphotericin B use, fungal infection, stable neutrophil count > 0.5 x 10(9)/L, toxicity precluding further fluconazole use, and death. By Kaplan-Meier estimation, the time to initiation of amphotericin B therapy was shorter in 76 patients treated with placebo than in 75 treated with fluconazole (P = .003). Also, fluconazole reduced the number of febrile days by 20% (P = .002) and prevented oropharyngeal candidiasis (1/75 vs. 9/76, P = .018). The frequency of deep mycoses (8/76 vs. 8/75) and outcome were unaffected.
Fluconazole
did not have a favorable effect on infection-related health care costs and was associated with prolonged severe
neutropenia
(P = .01).

The goal of this prospective randomized single-center study was the comparison of safety and efficacy of high-dose oral/intravenous fluconazole (400 mg daily) (group A) with oral nystatin plus miconazole inhalations (group B) in the prevention of fungal infections on a hemato-oncological isolation Ward. Of 157 patients admitted to the isolation ward during the study period only 90 (57%) were eligible for randomization; 22 (14%) had a fungal infection at admission. Of the 90 randomized patients, 89 were evaluable, 43 in group A and 46 in group B. The age, sex, diagnosis, planned therapy and risk factors for fungal infections at admission as well as the duration of
neutropenia
were in the same proportions in both groups. Oral thrush and mucocutaneous candidiasis were prevented in all patients of both groups, and 29 patients (32%: 17 in group A, 12 in group B) were discharged after successful prophylaxis (NS). Empiric amphotericin B was given according to predetermined criteria to 45 patients (51%: 23 group A, 22 group B; NS).
Fluconazole
significantly delayed the time before the start of intravenous amphotericin B. It was begun after a median of 10 days (0-45 days, range) of
neutropenia
below 0.5 x 10(9) granulocytes/l in group A and 7.5 days (0-26, range) in group B (P < 0.05). The duration of successful prophylaxis was significantly longer in group A (26 days median) than in group B (21 days, median) (P < 0.05). Systematic fungal infection was documented in 3 patients (1 group A, 2 group B; NS).

Fluconazole
has proved to be effective in treating oropharyngeal and esophageal candidiasis in immunocompromised patients. However, sufficient data are lacking regarding the efficacy of this agent in neutropenic hosts. The aim of the present study was to determine the clinical and mycological efficacy of fluconazole and to define the factor(s) affecting the outcome of fluconazole therapy in severely neutropenic patients (peripheral neutrophil count, < 500/microL) with cancer who have oropharyngeal and/or esophageal candidiasis. One hundred eleven patients with 129 episodes of candidal infections were treated with intravenous and consequently oral fluconazole (200 mg/d and 100 mg/d, respectively). Overall clinical cure and mycological eradication rates were 82% and 56%, respectively. Persistent
neutropenia
(P < .01), infection with a non-albicans strain of Candida (P = .012), and administration of antifungal therapy during the second or a later neutropenic episode (P < .002) were independently associated with a worse outcome. We conclude that fluconazole is effective in the treatment of upper gastrointestinal candidiasis in neutropenic patients with cancer. Effective treatment of the underlying malignancy, with the resultant recovery from
neutropenia
, and the determination of the species of infecting Candida isolates are required for the prediction of the outcome of antifungal therapy.

We studied the impact of fluconazole prophylaxis (400 mg/day) on clinical features including fever and use of amphotericin in a randomized, double-blind, placebo-controlled (1:1 randomization) study among patients undergoing chemotherapy for leukemia and those undergoing bone marrow transplantation.
Fluconazole
or placebo was given throughout the period of
neutropenia
. Amphotericin was administered to 5 of 23 (22%) fluconazole recipients and 14 of 23 (58%) placebo recipients (p < 0.01). Median duration of amphotericin used in fluconazole and placebo groups was 9 days (mean 10.8) and 13 days (mean 14) respectively. Patients who received fluconazole had significantly shorter duration of fever prior to treatment with amphotericin (days, median 5 vs. 9, p < 0.05). Superficial fungal infections were noted in 8 (34%) fluconazole recipients and 19 (79%) placebo recipients (p = 0.002).
Fluconazole
was well tolerated. Prophylaxis with fluconazole resulted in a significant reduction in the empiric use of amphotericin, duration of fever and incidence of superficial fungal infections.

The impact of prophylaxis with 400 mg/day fluconazole on fungal colonization at different body sites was assessed in a randomized, double-blind, placebo controlled study among patients with leukaemia and those undergoing bone marrow transplantation. The study drug was given throughout the period of
neutropenia
and samples were obtained at weekly intervals. Of the 23 patients in each group, 11 of those given fluconazole and 12 placebo recipients were colonized at entry. The commonest sites were the oropharynx and rectum and Candida albicans was the most frequent isolate.
Fluconazole
led to a marked reduction in colonization by the second week of treatment to 29% compared with 68% for those given the placebo. Two-weeks after stopping the study regimen there was little change with yeast being isolated from 33% and 81% respectively.
Fluconazole
was particularly effective in reducing the carriage of C. albicans in the oropharynx from 46% to 0-10% and in maintaining this throughout prophylaxis. Recovery of Candida (Torulopsis) glabrata from the perianal region steadily increased to around 30% in both patient groups and while Candida krusei species were found exclusively in patients given fluconazole, other candida were more common in the placebo group. These results demonstrate that by rapidly reducing the colonization of the alimentary tract, fluconazole eliminates the major reservoir for infection with yeasts other than C. glabrata and C. krusei during the critical period of
neutropenia
.
