Infections caused by Candida spp. are a major cause of morbidity and mortality in critically ill patients and usually develop from endogenous colonization. We assessed the effectiveness of adding fluconazole to a selective digestive decontamination regimen to prevent candidal infections.
                We performed a prospective, randomized, double-blind, placebo-controlled trial among medical and surgical intensive care unit patients at a large university hospital.
                All adult patients mechanically ventilated for at least 48 h with an expectation to remain so for at least an additional 72 h, and receiving selective decontamination of the digestive tract.
                Patients were randomly assigned fluconazole 100 mg daily (n=103) or placebo (n=101).
                Candida infections occurred less frequently in the fluconazole group (5.8%) than in the placebo group (16%; rate ratio 0.35; Cl(95) 0.11-0.94). Some 90% of candidemia episodes occurred in the placebo group (rate ratio for fluconazole use 0.10; Cl(95) 0.02-0.74). The rate of treatment failure, development of candidal infection, or increased colonization, was 32% in the fluconazole group and 67% in the placebo group (P<0.001). Crude in-hospital mortality was similar in the two groups (39% fluconazole vs. 41% placebo).
                Prophylactic use of fluconazole in a selected group of mechanically ventilated patients at high risk for infection reduces the incidence of Candida infections, in particular candidemia. To evaluate the prophylactic use of enteral fluconazole to prevent invasive candidal infections in critically ill surgical patients.
                Invasive fungal infections are increasingly common in the critically ill, especially in surgical patients. Although fungal prophylaxis has been proven effective in certain high-risk patients such as bone marrow transplant patients, few studies have focused on surgical patients and prevention of fungal infection.
                The authors conducted a prospective, randomized, placebo-controlled trial in a single-center, tertiary care surgical intensive care unit (ICU). A total of 260 critically ill surgical patients with a length of ICU stay of at least 3 days were randomly assigned to receive either enteral fluconazole 400 mg or placebo per day during their stay in the surgical ICU at Johns Hopkins Hospital.
                The primary end point was the time to occurrence of fungal infection during the surgical ICU stay, with planned secondary analysis of patients "on-therapy" and alternate definitions of fungal infections. In a time-to-event analysis, the risk of candidal infection in patients receiving fluconazole was significantly less than the risk in patients receiving placebo. After adjusting for potentially confounding effects of the Acute Physiology and Chronic Health Evaluation (APACHE) III score, days to first dose, and fungal colonization at enrollment, the risk of fungal infection was reduced by 55% in the fluconazole group. No difference in death rate was observed between patients receiving fluconazole and those receiving placebo.
                Enteral fluconazole safely and effectively decreased the incidence of fungal infections in high-risk, critically ill surgical patients. To evaluate the efficacy and safety of intravenous fluconazole for the prevention of intra-abdominal Candida infections in high-risk surgical patients.
                Randomized, prospective, double-blind, placebo-controlled study.
                Two university-affiliated hospitals in Switzerland.
                Forty-nine surgical patients with recurrent gastrointestinal perforations or anastomotic leakages.
                Prophylaxis with intravenous fluconazole (400 mg per day) or placebo continued until resolution of the underlying surgical condition.
                Patients were evaluated daily, and specimens for culture were obtained three times per week during prophylaxis. The primary study end points were the frequency of and the time to intra-abdominal Candida infections. Secondary end points were the frequency of candidiasis (intra-abdominal and extra-abdominal) and the emergence or persistence of Candida colonization. Among patients who were not colonized at study entry, Candida was isolated from surveillance cultures during prophylaxis in 15% of the patients in the fluconazole group and in 62% of the patients in the placebo group (relative risk, 0.25; 95% confidence interval, 0.07 to 0.96; p = .04). Candida peritonitis occurred in one of 23 patients (4%) who received fluconazole and in seven of 20 patients (35%) who received placebo (relative risk, 0.12; 95% confidence interval, 0.02 to 0.93; p = .02). In addition, one catheter-related Candida albicans sepsis occurred in a fluconazole-treated patient. Thus, overall, candidiasis developed in two fluconazole patients and seven placebo patients (relative risk, 0.25; 95% confidence interval, 0.06 to 1.06; p = .06). C. albicans accounted for 87% of the Candida species isolated before or during prophylaxis, and all C. albicans strains were susceptible to fluconazole. Fluconazole was well tolerated, and adverse events occurred at similar frequencies in both treatment groups.
                Fluconazole prophylaxis prevents colonization and invasive intra-abdominal Candida infections in high-risk surgical patients. Three clinical studies have suggested that ketoconazole, a synthetic imidazole with anti-inflammatory activity, may prevent the development of acute respiratory distress syndrome (ARDS) in critically ill patients. However, the use of ketoconazole as treatment for acute lung injury (ALI) and ARDS has not been previously studied.
                To test the efficacy of ketoconazole in reducing mortality and morbidity in patients with ALI or ARDS.
                Randomized, double-blind, placebo-controlled trial conducted from March 1996 to January 1997.
                Twenty-four hospitals associated with 10 network centers in the United States, constituting the ARDS Network.
                A total of 234 patients with ALI or ARDS.
                Patients were randomly assigned to receive ketoconazole, 400 mg/d (n = 117), or placebo (n = 117), initiated within 36 hours of fulfilling study entry criteria and given enterally for up to 21 days.
                Primary outcome measures were the proportion of patients alive with unassisted breathing at hospital discharge and the number of days of unassisted breathing (ventilator-free days) during 28 days of follow-up. Secondary outcome measures included the proportion of patients achieving unassisted breathing for 48 hours or more, the number of organ failure-free days, and changes in plasma interleukin 6 (IL-6) and urinary thromboxane A2 metabolites (thromboxane B2 [TXB2] and 11-dehydro-TXB2).
                In-hospital mortality (SE) was 34.1% (4.3%) for the placebo group and 35.2% (4.3%) for the ketoconazole group (P=.85). The median number of ventilator-free days within 28 days of randomization was 9 in the placebo group and 10 in the ketoconazole group (P=.89). There were no statistically significant differences in the number of organ failure-free days, pulmonary physiology, or adverse events between treatment groups. The median serum ketoconazole level was 1.25 microg/mL and serum levels greater than 0.5 microg/mL were detected in 96% of patients assayed. Plasma IL-6, urinary TXB2, and 11-dehydro-TXB2 levels were unaffected by ketoconazole.
                In these patients with ALI or ARDS, ketoconazole was safe and bioavailable but did not reduce mortality or duration of mechanical ventilation or improve lung function. These data do not support the use of ketoconazole for the early treatment of ALI or ARDS. To investigate the prevention and therapy of fungal infection in patients with severe acute pancreatitis (SAP).
                Seventy patients with SAP admitted from Jan. 1998 to Dec. 2002 were randomly divided into garlicin prevention group, fluconazole (low dosage) prevention group and control group. The incidence of fungal infection, the fungal clearance and mortality after treatment were compared.
                The incidence of fungal infection in garlicin group and fluconazole group was lower than that in control group (16% vs 30%, P<0.05 and 9% vs 30%, P<0.01, respectively). Amphotericin B or therapy-dose fluconazole had effects on patients with fungal infection in garlicin group and control group, but had no effects on patients with fungal infection in fluconzole group.
                Prophylactic dosage of antifungal agents (garlicin or low dosage fluconazole) can reduce the incidence of fungal infection in patients with SAP. But once fungal infection occurs, amphotericin B should be used as early as possible if fluconazole is not effective. Determine the significance of recovering yeasts from intraoperative specimens from the abdominal cavity and to evaluate the effect of a single intraoperative dose of fluconazole on clinical outcome in patients with intra-abdominal perforations.
                Prospective, randomized, double-blind study.
                Multicenter study from 13 hospitals in Norway.
                One hundred nine patients with intra-abdominal perforations.
                Patients were randomized to receive either a single 400-mg fluconazole dose or placebo during the operation.
                An intra-abdominal specimen for microbiological culture was obtained at the time of the operation. The primary response variable in the study was death. Secondary response variables were three parameters indicating a complicated postoperative period: mechanical ventilation for > or = 5 days, intensive care treatment for > or = 10 days, and use of a central venous catheter for > or = 10 days. Yeasts were recovered from a intraoperative intra-abdominal specimen from only 1 (3.5%) of 28 patients with perforated appendicitis and from 32 (39.5%) of 81 nonappendicitis patients. Excluding the appendicitis patients, the yeast recovery rate was high both for patients hospitalized at the time of the perforation (45%) and for nonhospitalized patients (32%). The overall mortality was 11% (12 patients). Single-dose intraoperative fluconazole prophylaxis did not reach a statistically significant effect on mortality (4 of 53 patients in the fluconazole group and 8 of 56 patients in the placebo group died [p = .059]). The only two explanatory variables significantly related to death were a intraoperative finding of yeast from an intra-abdominal specimen and the occurrence of a spontaneous perforation in a patient already hospitalized for nonsurgical cancer treatment. Detection of yeast was also a significant explanatory variable for a prolonged period of mechanical ventilation, intensive care treatment, and prolonged use of a central venous catheter.
                Single-dose intraoperative fluconazole prophylaxis did not have a statistically significant effect on overall mortality (odds ratio = 0.21; 95% confidence interval, 0.04-1.06; p = .059) in patients with intra-abdominal perforation. The recovery rate of yeast from intraoperative specimens from the abdominal cavity was high (>30%) and was associated with death and a complicated postoperative course. A prospective, randomized study was conducted to determine if prophylactic antifungal agents prevented yeast colonization (YC) or yeast sepsis (YS), or if they diminished mortality in 292 critically ill adult (nontransplant/nonburned) surgical and trauma patients admitted to the SICU for 48 hours or longer. Patients were randomized to receive (group I) no therapy, (group II) clotrimazole 10 mg three times a day, (group III) ketoconazole 200 mg per day, or (group IV) nystatin 2 million units every 6 hours. For comparison patients were stratified by the criteria of Slotman and Burchard into high risk (> or = 3 risk factors) and low risk (< 3 risk factors). Fifty patients (17%) had yeast colonization, nine (3.1%) had yeast sepsis, and 41 (14%) died. Stepwise logistic regression analysis of yeast colonization and sepsis using the variables APACHE II scores > 10, need for ventilator support > 48 hours, and 14 risk factors (Slotman and Burchard) showed that treatment with three or more antibiotics, APACHE II > 10, and ventilatory support > 48 hours were the only three variables that were significant predictors of yeast colonization and sepsis. There was no significant difference between the four groups with regard to YC (23%, 18%, 12%, and 15%, respectively), YS (3%, 1%, 2%, and 7%, respectively), or mortality (15%, 14%, 6%, and 20%, respectively).(ABSTRACT TRUNCATED AT 250 WORDS) To determine if ketoconazole, a thromboxane A2 synthetase inhibitor, given within the first 24 hrs after diagnosis and arrival in the intensive care unit (ICU) would decrease the frequency of adult respiratory distress syndrome in the septic patient population.
                Prospective, randomized, double-blind, placebo-controlled study.
                Twelve-bed, surgical ICU in a university-affiliated hospital.
                Fifty-four consecutive patients admitted to the surgical ICU with the diagnosis of sepsis composed the study sample. Sepsis was defined as including two or more of the following signs in a patient with a systolic blood pressure of < 80 mm Hg or a systemic vascular resistance of < 800 dyne.sec/cm5: a) temperature > or = 39 degrees C or < or = 35 degrees C; b) white blood cell count of > 12,000 leukocytes, or < or = 4000 leukocytes/microL, or > or = 20% immature cells; c) positive blood culture; d) known or strongly suspected source of infection from which a known pathogen was cultured.
                Patients were randomized to receive either ketoconazole (400 mg) or placebo in a double-blind fashion as early as possible and in < 24 hrs after surgical ICU admission or after the diagnosis of sepsis was established.
                Adult respiratory distress syndrome (ARDS) was diagnosed if the following criteria were met: a) intrapulmonary shunt of > 20%, or a PaO2/FIO2 ratio of < 150 requiring ventilatory support for > 48 hrs; b) pulmonary artery occlusion pressure of < 18 mm Hg and no clinical signs of heart failure; and c) diffuse infiltrates on chest radiograph. Treatment resulted in significant (p = .002) reduction in the frequency of ARDS compared with the placebo group, 64% vs. 15% in the ketoconazole treated group. The mortality rate was also reduced from 39% in the placebo group to 15% in the ketoconazole group (p = .05). A statistically significant reduction in ventilator and ICU days was not achieved.
                Ketoconazole (400 mg through the gastrointestinal tract) given early in the septic course may prevent ARDS and decrease the mortality rate in high-risk, septic patients. We conducted a prospective, randomized, double-blind, placebo-controlled study to determine whether or not ketoconazole could prevent yeast colonization or invasion in critically ill adult surgical patients. Fifty-seven patients in a surgical intensive care unit (SICU) with three or more clinical risk factors for Candida infection were randomized to receive ketoconazole, 200 mg via the gastrointestinal tract daily (27 patients), or placebo (30 patients). Patients with hepatic dysfunction were excluded. The study was continued for 21 days or until one week after discharge from the SICU, whichever was longer. Stool cultures were obtained every three days and other cultures as indicated clinically. Patients were observed for yeast colonization (sputum, urine, stool, or wound) and invasion (fungemia or deep tissue focus). The incidence of Candida colonization was significantly lower in the ketoconazole group than the placebo group. Invasive yeast sepsis developed in five (17%) of the placebo-treated patients and in no patient in the ketoconazole group, a significant difference. Length of stay in the SICU was significantly lower in the ketoconazole group, as were the basic SICU patient charges. Sixty percent of the patients with invasive fungal sepsis died. To demonstrate whether fluconazole reduces multiple organ failure and mortality in early septic shock (<24 hrs).
                A prospective randomized double-blind study.
                A medical and surgical adult intensive care unit in a tertiary referral center.
                Values were obtained from 71 general adult intensive care unit patients.
                During a 2.5-yr period, December 1998-June 2001, 71 patients with septic shock attributed to either nosocomial pneumonia (n = 37) or intra-abdominal sepsis (n = 34) were admitted to our intensive care unit and met the criteria of early septic shock and were entered into this study. All patients were randomized by our clinical pharmacist to receive daily either 200 mg of fluconazole in isotonic saline (fluconazole group = 32) or isotonic saline alone (placebo group = 39) intravenously during the course of their septic shock.
                All patients were closely monitored with pulmonary artery catheters and parameters to calculate daily organ dysfunction and Acute Physiology and Chronic Health Evaluation II scores. There was a highly significant increase in 30-day survival in the fluconazole-treated patients compared with the placebo patients (78% vs. 46%). However, fluconazole was found to be more effective in patients with septic shock attributed to intra-abdominal sepsis than to nosocomial pneumonia. Increased survival in the intra-abdominal sepsis clinical category was mirrored by a significantly lower number of organ failures in the treated group compared with the placebo group whereas the number of organ failures in the fluconazole group attributed to nosocomial pneumonia were not significantly increased compared with the control group. The septic shock state was considered in all cases to be attributed to bacterial and not to disseminated yeast infection with the exception of one patient in the control group who was admitted with candidemia. The mechanisms by which fluconazole exerts its protective effect against septic shock in patients is far from clear. However, fluconazole has been shown to enhance bactericidal activity of neutrophils and also to inhibit transmigration and adhesion of neutrophils in capillaries of distant organs.
                The development of organ failure and mortality in septic shock was significantly reduced by fluconazole given intravenously. The mechanism of action of fluconazole in reducing multiple organ dysfunction in this group of patients may be attributed to the ability of fluconazole to increase recruitment, improve bactericidal activity of neutrophils, and to contain microorganisms locally.
Prophylaxis with fluconazole or ketoconazole in critically ill patients reduces invasive fungal infections by one half and total mortality by one quarter. Although no significant increase in azole-resistant Candida species associated with prophylaxis was demonstrated, trials were not powered to exclude such an effect. In patients at increased risk of invasive fungal infections, antifungal prophylaxis with fluconazole should be considered.
