A 33-yr-old Puerto Rican women was hospitalized for chemotherapy and multiple antibiotic treatment for relapse of acute myelomonocytic leukemia. While she was already receiving amphotericin for suspected Aspergillus infection, she developed hepatomegaly and abnormal liver enzymes with high serum bilirubin. The blood cultures were negative. Percutaneous liver biopsy revealed granulomatous fungal hepatitis identified by cultures as Trichosporon cutaneum. In spite of the continued administration of amphotericin, with the addition of 5-fluorocytosine, Trichosporon was later cultured from her blood, and she succumbed to fungemia and polymicrobial sepsis.

Fungemias were reviewed in 110 immunocompromised patients hospitalized between November 1, 1974, and December 31, 1977, a Memorial Sloan-Kettering Cancer Center (MSKCC). The incidence of Candida tropicalis fungemia increased each year. Seventy-six percent of the patients with C. tropicalis fungemia and 32.5 percent of those with C. albicans fungemia had either leukemia or lymphoma. Seventy-seven percent of the C. parapsilosis fungemias were related to total parenteral nutrition. Thirty-seven percent of the patients with C. albicans fungemia were receiving oral prophylactic nystatin therapy. The source of fungemia was often difficult to determine: in 60 percent of the patients, only blood cultures were positive for C. tropicalis or Torulopsis glabrata; no cultures were positive for the fungus from any other site before the episode occurred. Serologic tests, including a highly sensitive passive hemagglutination test, showed fourfold increases in titer only inconsistently. A passive hemagglutination-inhibition test for circulating antigen was positive in 50.9 percent of 57 patients with fungemia who were tested and may be a valid indication for treatment. Fungemia usually represented a severe and often fatal disease. The over-all mortality of the 110 patients with fungemia was 79 percent whereas only 23 percent of the patients with C. parapsilosis fungemia died. Among the patients who received more than 200 mg of amphotericin B, 71 percent died despite treatment.

A 67-year old man with acute myelomonocytic leukemia had Candida albicans fungemia during induction chemotherapy. Bilateral pulmonary infiltrates and hepatic granulomata containing yeast forms and septate hyphae developed, but cultures of the hepatic tissue failed to grow a fungus. Although his pulmonary and liver disease improved following appropriate therapy, vertebral osteomyelitis due to Candida albicans developed approximately 12-15 weeks after the original fungemia. The fungal osteomyelitis was successfully treated with amphotericin B and 5-fluorocytosine. This case illustrates the need for early diagnosis and aggressive treatment of fungal infections in patients with leukemia.

Candida parapsilosis fungemia secondary to nasal colonization following application of nasal prongs for oxygen therapy developed in a 61-year-old man with known chronic lymphocytic leukemia and pulmonary infiltrates. Amphotericin B controlled the candidal infection, but the patient died of complications related to Aspergillus pneumonitis, intra-abdominal mucormycosis, and leukemia. The source of candidal infection was probably a combination of nasal ulceration resulting from oxygen administration by nasal prongs and alteration of the normal mucosal flora by multiple broad-spectrum antibiotics. Oxygen administration by mask to patients at risk of opportunistic infections may help obviate this potential complication, with its attendant danger of spread to the brain and cavernous sinuses. We discuss the rarity of triple infection with these three organisms.

Despite the use of conventional chemoprophylaxis regimens, patients receiving unrelated-donor BMT are at high risk of developing severe acute GVHD. We evaluated a prophylactic regimen combining CsA, MTX and anti-CD5-ricin A chain immunotoxin (H65-RTA) in 31 patients; pentoxifylline was also given to reduce the anticipated nephrotoxicity of CsA. In most cases, planned doses of CsA, MTX and H65-RTA were given (i.e. to 77%, 77% and 93% of patients, respectively). Although fluid retention requiring diuretic therapy was frequent, only 1 patient had a > 10% unexplained increase in body weight during the first 21 days post-BMT. Also, while significant increase of the baseline serum creatinine was noted in 7 patients, none required dialysis. One patient suffered a reversible allergic reaction to the immunotoxin; no other side effects attributable to this regimen were observed. All but 2 patients engrafted (1 died of fungemia on d + 19 and the other had persistent leukemia) and no late graft failures were observed. Seventeen patients developed acute GVHD grade > or = II (probability, 58% [95% CI 41-76%]); 7 had grade > or = III (probability, 24% [95% CI 12-43%]). In the 27 patients who achieved stable engraftment and have survived beyond d + 100, the 3-year probability of developing chronic GVHD was 66% (95% CI 48-84%). As of the last follow-up prior to 01 May 1994, 13 patients are alive in CR and one in relapse; 9 of these patients are off all immunosuppressives and well. Four other patients relapsed and died, and 13 died of other transplant-related causes.(ABSTRACT TRUNCATED AT 250 WORDS)

Endogenous fungal endophthalmitis is being increasingly recognized in susceptible individuals. We report a case of endogenous endophthalmitis due to Fusarium solani that occurred as the sole clinical manifestation of fungal disease in an immunocompromised host. Four previously reported cases of endogenous fusarial endophthalmitis are also reviewed. Two of these patients had no underlying disease and presented with isolated endophthalmitis, while two other patients had acute leukemia and presented with multiple organ involvement due to Fusarium. All three patients with leukemia, including our patient, were severely neutropenic at the time of diagnosis. Two of these three patients had fungemia. MICs of amphotericin B for fungal isolates ranged from 0.14 to 10 micrograms/mL. Despite abatement of the endophthalmitis after antifungal therapy and vitrectomy, the prognosis for immunocompromised patients remains guarded because of underlying disease.

Hickman catheters were the major venous access devices utilized at the University of Maryland Cancer Center from November 1978 to 1987. This study provided an opportunity to standardize insertion technique, to manage catheter-related activities and daily maintenance procedures in order to examine the progression of Hickman-catheter-related problems, to identify those factors that may minimize them, and to develop guidelines for the management and prevention of complications and malfunctions. In all, 690 Hickman catheters (368 double lumens) were placed in patients with acute leukemia and other cancers: 401 catheters were placed in patients with leukemia; 269 were placed during neutropenia; and 230 at platelet counts of < 50,000/microliters. Two surgeons inserted 490 catheters, and the remaining 200 were placed by a group of rotating surgeons. All catheters were placed with the intention that they would remain in place as long as clinically necessary. Total Hickman catheter days were 134273. Infectious complications included exit site infections (160), tunnel infections (46) and bacteremias (397). There were 438 instances of noninfectious complications including thrombosis, lack of function, catheter migration, fracture and hemorrhage. Recommendations for prevention and treatment of Hickman-catheter-related complications include the development of a select group committed to placement, daily maintenance and management of problems; prompt removal of catheters with Candida sp. fungemia and bacteremia due to Bacillus sp. or a bacteremia that persists for > 48 h after initiation of appropriate antibiotics, tunnel infections or Hickman-catheter-associated thrombosis. The majority of bacteremias and exit site infections can be effectively treated with antibiotics and local care.

Five episodes of fungemias are described; all had occurred in children with leukemia or lymphoma between January 1, 1978 and December 31, 1990. These fungemias comprised 3.4% of the total septicemias encountered during that period. Three episodes occurred during the induction phase and two during relapse. All patients had fever of varying degree and duration. In addition to steroids, all were receiving combination antibiotics before the fungemia had occurred. All patients had severe neutropenia lasting more than one week. Bacteremia preceded fungemia in four patients. Two episodes were diagnosed antemortem. The same species were isolated from other sites in three cases. Fever, chills and gastrointestinal symptoms were the most common clinical features; other symptoms included cough, dyspnea, oliguria and azotemia. One patient experienced skin lesion, dysphagia, hoarseness and hemiparesis. Only one patient survived. The prognosis from fungemia in leukemia and lymphoma patients is very poor. Empiric antifungal therapy is indicated in neutropenic patients who have recurrent or persistent fever despite one week of broad spectrum antibiotics. Early diagnosis and treatment will aid in improving the overall poor outcome of this disease.

A nine-year retrospective study on fungemia in patients with leukemia was conducted. A total of 79 episodes of fungemia in 77 patients with leukemia were documented. Candida parapsilosis fungemia was associated more frequently with the presence of a central venous line and to the use of parenteral nutrition than the other fungal species (p = 0.00026 and p = 0.01, respectively). The same fungus was isolated from both blood and surveillance cultures in 95% of Candida albicans and in 89% of Candida tropicalis fungemia (p < 0.01 and p = 0.02, respectively). The neutropenia and fungus colonization that resulted was associated significantly with the presence of invasive disease (p = 0.0024 and p = 0.0028, respectively). Conversely, central venous catheterization and parenteral nutrition appeared to be associated with episodes without deep tissue invasion (p = 0.000037 and p = 0.001, respectively). Invasive mycosis due to the fungus isolated from blood was documented in 51 patients with a mortality rate of 69%, whereas in 20 patients without invasive mycosis, mortality rate was 21% (p = 0.000059). In patients with fungemia, related or unrelated to the presence of a central venous catheter, mortality was 24% and 64%, respectively (p = 0.00042). Mortality was highest with C. tropicalis (p = 0.0017) and lowest with C. parapsilosis (p = 0.057). Severe neutropenia (polymorphonuclears < 100/mmc) appeared associated with a higher mortality rate (p = 0.012), whereas the recovery of neutropenia was related adversely to a fatal outcome (p < 0.01). With antifungal therapy, there was no statistically significant difference whether antifungal therapy was given or not.(ABSTRACT TRUNCATED AT 250 WORDS)

The Candida species account for approximately three-fourths of fungal infections in patients with cancer. Although Candida albicans is the most frequent cause, C. tropicalis is increasingly implicated as an important pathogen. Over a 12 year period 19 children treated for leukemia at our institution developed C. tropicalis infections. We describe their clinical presentation, extent of fungal infection, treatment, and outcome. Fungemia without meningitis in 11 children was treated successfully, whereas C. tropicalis meningitis in 7 children was uniformly fatal. An additional patient had unsuspected, widespread infection detected at autopsy. Multiple sites, including the cerebrospinal fluid yielded C. tropicalis. Previously reported risk factors including neutropenia, broad-spectrum antibiotic usage, corticosteroid therapy, and total parenteral nutrition were observed in our cases. A high index of suspicion and the early use of aggressive antifungal therapy are critical to the successful management of C. tropicalis infections in children with leukemia.
