Mycotic peritonitis can be demonstrated by microbiological, histological and serological tests. The disease can be proved histologically by a deep invasion of fungi. Initially, the mycotic peritonitis can be caused by polymicrobial infections and also by genuine mycotic invasion after perforation of the gastrointestinal tract. In the final phase of the disease only these fungi are of relevance. In most of the cases candida albicans can be verified. In the procedure of programmed peritoneal lavage the mycotic peritonitis provides a severe complication. Untreated, it would cause death by dissemination, fungemia and candida sepsis. 8 out of 12 patients with candida peritonitis died. Most of the patients had been severely ill previously and had shown several risk factors promoting mycotic disease. Antimycotic treatment has to be initiated as soon as possible, in order to diminish the high lethality.

Sepsis due to Candida parapsilosis with involvement of the joints and the lungs, respectively, is reported in two patients with acute leukemia. The first patient had ankle arthritis 72 days after an allogenic bone marrow transplant for acute lymphoblastic leukemia. The second patient had pneumonia with cavitation during pancytopenia after chemotherapy for acute monocytic leukemia. In both cases, C. parapsilosis sepsis responded to therapy with amphotericin B, associated with miconazole in the first patient and with 5-fluorocytosine in the second one. The rarity of septic foci during C. parapsilosis fungemia and the good outcome of both patients are emphasized. This good result was probably due to early antifungal therapy and the relatively rapid recovery of granulocytopenia.

We report seven elderly patients with COPD who developed serious infectious complications during prolonged treatment with high doses of corticosteroids. Infections included invasive pulmonary aspergillosis, Herpes simplex stomatitis and esophagitis, cytomegalovirus pneumonia, bacterial sepsis, fungemia and meningitis due to Cryptococcus neoformans. Each of the three patients who developed invasive aspergillus pneumonia died. The efficacy of prolonged therapy with high doses of corticosteroids in patients with COPD is not proven. These cases illustrate the potential for serious infections in patients with COPD treated with corticosteroids.

One hundred and ninety-five episodes of fever during the neutropenic phase of chemotherapy in 49 patients with acute leukemia from 1984 to 1987 were analyzed with the following results: 1) Febrile episodes occurred in 80 percent of the neutropenic (less than 500/microliters) phase lasting more than 7 days after chemotherapy. 2) Febrile episodes consisted of 44 (22%) of established septicemia and 111 (57%) of suspected septicemia. 3) The pathogens causing septicemia were 8 GPC, 38 GNB (22 Pseudomonas species) and 6 fungi. Fungemia was confirmed on an average of 4.8 days after the onset of fever. The mortality of septic events was 10 out of 17 episodes (59%) when treated with antibiotics alone, while 8 out 27 (30%) with the combination of antibiotics plus antifungal drugs. 4) The mortality of suspected sepsis was only 2 out of 111 episodes. Eighty-three (75%) of these 111 episodes responded to antibiotics alone, while 26 (23%) cases needed antibiotics plus antifungal drugs. Our results suggest that in febrile neutropenic patient empiric broad-spectrum antibiotic therapy should be initiated which is especially effective for Pseudomonas species, but if fever persists despite more than 4 or 5 days of antibiotic therapy, additional antifungal therapy should be considered.

Fungal infection of central venous catheters is well described. Peripheral fungal thrombophlebitis, however, has only been recognized recently, is thought rare, and is poorly characterized as to clinical presentation and treatment. We report the cases of eight patients with peripheral Candida thrombophlebitis. Patients were elderly and critically ill. All had received broad-spectrum antibiotics. Skin colonization appeared the source of contamination. Sepsis, shock, and organ failure were frequent. Physical findings of fungal phlebitis may be subtle, and diagnosis is often delayed. Multiple sites are frequently involved. Treatment necessitates radical excision of suspected veins and systemic antifungal chemotherapy. Persistent fungemia suggests inadequate phlebectomy or the existence of further affected veins. Peripheral thrombophlebitis is probably a common source of fungal sepsis and should be considered in all patients with fungemia. Without aggressive surgical intervention, survival is unlikely.

Until recently, Malassezia furfur was thought to be a pathogen only in tinea versicolor. More recently, this lipophilic yeast has been recovered from sick neonates with catheter-related infections. Malassezia fungemia was studied in seven patients, and the salient features of this infection in patients described in the literature were reviewed. Major risk factors include prolonged hospitalization, the presence of central venous catheters, and the use of intravenous fat emulsions. It is difficult to identify specific manifestations of fungemia in these complex cases occurring in patients with severe underlying disease; however, neonates often present with the signs and symptoms of sepsis and thrombocytopenia, whereas fever may be the only manifestation in adults. Some patients are asymptomatic. When symptoms are present, they resolve upon removal of the colonized catheter. The role of the lipophilic nature of Malassezia in the pathogenesis of infection is apparent from the ability of intravenous fat emulsions to support the growth of the fungus in vitro. A special solid medium that can be used to determine the true prevalence of malassezia fungemia has been devised. M. furfur must be considered in the differential diagnosis of opportunistic infections in patients receiving central hyperalimentation and should be sought by the culture of blood on appropriate medium.

Mixed septicemia (synchronous fungal and bacterial septicemia) is an occasional, but often fatal occurrence in the critically ill patient. We reviewed 14 such cases at two hospitals. Twelve of 14 patients were in the surgical intensive care unit. Eleven patients had an average of 2.7 major surgical procedures (range 2 to 4); persistent post-operative peritoneal sepsis was common occurring in 9 patients. Bacteremia preceded mixed septicemia in 8 of 14 cases and gram negative enteric bacilli were the most common causes of bacteremia. Fungemia was due to Candida species in 13 of 14 patients and followed prolonged antibiotic therapy. The diagnosis of disseminated candidiasis was suspected during life in 13 patients and proven in six. Mixed septicemia is a marker for a distinct population of critically ill surgical patients with a high overall mortality (78% in this study). Culture of both a fungal and bacterial pathogen in a blood culture, especially if preceded by bacteremia, should alert the physician to strongly suspect disseminated fungal infection and to commence appropriate treatment. Mortality is likely to remain high unless the underlying disease states can be rapidly corrected and infection controlled.

Malassezia pachydermatis, a yeast that has not previously been implicated as a cause of human disease, was isolated from cultures of blood from three infants. All infants were 25-27 w of gestational age and had multiple underlying medical problems. The infants had been hospitalized for at least six weeks, had received broad-spectrum antibiotics, and had received parenteral lipid nutrition via a central venous catheter. In one patient, fungemia was accompanied by clinical and laboratory evidence of Broviac catheter infection. During a three-year period, M. pachydermatis was also recovered from fungal cultures of an additional 30 patients, 85% of whom were infants. A pathogenic role for M. pachydermatis recovered from sources other than blood or catheters was not established. Risk factors for and symptoms in infants with M. pachydermatis fungemia appeared to be similar to those described for Malassezia furfur sepsis.

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.

Although the addition of 1.2% gelatin to broth blood culture media containing sodium polyanetholesulfonate has been shown to enhance detection of certain bacteria, including Neisseria meningitidis, N. gonorrhoeae, Peptostreptococcus anaerobius, and Gardnerella vaginalis, the effect of such supplementation on the detection of other microorganisms causing bacteremia and fungemia is not known. Therefore, we studied BACTEC 6B medium with and without gelatin in 6,833 paired comparisons to examine the effects of supplementation on both the yield and the speed of detection of sepsis. More aerobic and facultative bacteria grew in the 6B than in the 6B-gelatin medium (P less than 0.001), especially staphylococci (P less than 0.01), Escherichia coli (P less than 0.01), other members of the family Enterobacteriaceae (P less than 0.05), and Acinetobacter spp. (P less than 0.05). When microorganisms grew in both bottles, they did so earlier in 6B than in 6B-gelatin (P less than 0.001). We conclude that the 6B medium in its present formulation is superior to 6B medium supplemented with 1.2% gelatin.
