Twenty-two preterm infants with systemic candidiasis are reported, of which seven cases were presumed to be antenatally acquired and 15 postnatally acquired. All except one were of very low birthweight. Fifteen infants had positive cultures of blood, cerebrospinal fluid or urine and seven had candida pneumonia only. Clinical features included general instability, respiratory deterioration and a necrotizing enterocolitis-like presentation. The incidence of leukocytosis, shift to the left, eosinophilia and thrombocytopenia were not different from those with bacterial infection. The diagnosis was made after death in two infants. In the remaining 20 infants, treatment was initiated between 5 and 97 days of age, with a median delay of 4 days after the first positive cultures were taken. Complications of amphotericin and 5-flucytosine therapy which developed in five infants resolved on cessation of treatment. The mortality rate was 18% and impairment rate among the 17 very low birthweight survivors was 18%. A high index of suspicion is required for systemic candidiasis, especially in infants of less than 1000 g birthweight. If recognized early, effective and safe antifungal therapy is possible with favourable short- and long-term outcome.

Systemic fungal infections have long been recognized in terminally ill patients with cancer. Systemic candidiasis is the most common, the incidence having increased in the last few years. Eight children diagnosed as having systemic candidiasis during a two-year period (1987-1988) are presented. Three had an isolated fungal pneumonitis, two an hepatosplenic candidiasis, one a multisystemic involvement (hepatosplenic, pulmonary and nodular skin lesions) and the remaining two patients had a Candida sepsis with no visceral lesions having been documented. All patients had neutropenia and prolonged fever no responsive to broad spectrum antibiotics. We would like to underline the importance of an early and prolonged antifungal therapy, especially in hepatosplenic candidiasis, in order to obtain the cure.

Combined immunodeficiency was documented in a 6-week-old Angus calf. The calf had lymphopenia, undetectable serum IgM or IgA, and low concentrations of serum IgG (420 mg/dl). The calf was treated for diarrhea, pneumonia, and shock, and was given antimicrobial drugs, fluids, and plasma. The calf died of systemic candidiasis and Escherichia coli bacteremia. Aggregated lymphatic folliculi (Peyer patches), lymph nodes, and thymic and splenic lymphoid tissue could not be identified at necropsy.

Isolation of Candida albicans from the vaginal secretions of pregnant women occurs with an incidence of 5-23%. Intrauterine infection caused by Candida during pregnancy is relatively rare; only 81 cases, all diagnosed after delivery, have been reported. We report six cases of candidal chorioamnionitis diagnosed by amniocentesis and confirmed by histologic studies, associated with preterm labor and delivery of five viable infants. Three of the six maternal patients had intrauterine contraceptive devices in situ. Three infants had a diagnosis of congenital cutaneous candidiasis and two had congenital systemic candidiasis, one with monilial pneumonia, and one with meningitis and septicemia. All viable neonates were treated successfully. The sixth, a very immature infant, died soon after delivery. Torulopsis (Candida) glabrata was isolated from this amniotic fluid. C. Albicans is a pathogen that potentially may cause chorioamnionitis and has been associated with high mortality (94%) in infants weighing less than 1500 gm. Use of amniocentesis in patients with preterm labor may allow early detection of subclinical candidal chorioamnionitis, thus guiding appropriate perinatal management.

To improve antemortem diagnosis of invasive pulmonary aspergillosis, we used a radioimmunoassay to detect an Aspergillus fumigatus antigen in bronchoalveolar lavage fluid (BALF) and evaluated this technique in a model of disseminated aspergillosis. Antigen was detected in 91% of BALF samples obtained from 11 rabbits with major pulmonary aspergillosis. In an additional 10 rabbits with only minor pulmonary involvement, antigen was detected in 40% of concentrated lavage samples. In contrast, antigenlike activity was found in only 1 of 17 BALF samples from control animals with systemic candidiasis, in none of 9 control animals with staphylococcal pneumonia and in none of 10 normal control animals. Although antigen was present in the serum of 76% of animals infected with Aspergillus, 27% of those with major pulmonary involvement had antigen detected in BALF alone. We found that an extracellular microbial antigen can be detected in BALF and that this technique in the disseminated aspergillosis model is both sensitive and specific for invasive pulmonary disease.

Patients with previous invasive fungal infections (IFI) are at high risk of reactivation of the infection during BMT, even after an apparently curative antifungal treatment. We report four patients who suffered an IFI after intensive chemotherapy for acute leukemia and were later submitted for BMT. One patient had developed a chronic systemic candidiasis during consolidation chemotherapy and received prophylactic oral or iv fluconazole (200 mg daily) throughout BMT. Two patients developed an invasive pulmonary aspergillosis after intensive chemotherapy, one of them after salvage therapy for post-allogeneic BMT relapse and the other after consolidation therapy. The former patient underwent partial lobectomy after treatment with amphotericin B before a second allogeneic BMT was performed. Both patients received prophylactic itraconazole (400 mg daily by mouth) throughout the BMT procedure. The fourth patient had pneumonia caused by Scedosporium apiospermum (the anamorph form of the fungus Pseudallescheria boydii) during consolidation chemotherapy which was successfully treated with itraconazole. During BMT he also received oral itraconazole (400 mg daily) as prophylaxis against reactivation of the infection. All four patients had successful BMT and none had clinical, radiological or microbiological evidence of reactivation of IFI during BMT.

The herpes group of viruses, particularly Epstein-Barr virus (EBV), has frequently been implicated in the causation of reactive hemophagocytic syndrome (RHS) in the Western populations. EBV has also been implicated in the rare fulminant form of RHS occurring in Oriental children. However, our previous adult-predominant study indicated little clinical and serological evidence of EBV infection in patients with RHS in Hong Kong. In the present study, we further examined this issue using a more sensitive and specific technique for the demonstration of EBV, ie, in situ hybridization for EBV encoded RNA (EBER). The 43 Chinese patients studied were mostly adults with a mean age of 44 years, and a male to female ratio of 1.5:1. About two-thirds (28) of patients had associated malignant lymphoma at the time of diagnosis. Five patients had documented infection (typhoid fever 2; systemic candidiasis 1; adenovirus pneumonia 1; viral encephalitis 1), and two had systemic lupus erythematosus. EBER signals were detected in only 11 cases (25.6%). All positive cases were associated with malignant lymphoma, and the positive signals were exclusively localized to the lymphoma cells but not in the histiocytes. On comparing the results (11 of 28 cases positive; 39.3%) with our previous data on EBER-expression in malignant lymphomas in Hong Kong, no significant difference is observed in the frequency of EBV-positivity between the two groups of lymphomas. Thus, a definite pathogenetic link between EBV and lymphoma-associated RHS cannot be established. However, the overrepresentation of T and T/NK lineage lymphoma in this sample of lymphoma-associated with RHS (61%) versus nonselected cases of lymphomas (31%) suggests that it is the T and T/NK cell origin of the lymphoma rather than the EBV positivity that predisposes to RHS. Notwithstanding the previous findings, EBER in situ hybridization may still serve as a useful adjunct in the investigation of patients with RHS, because the presence of EBER-positive cells should raise a strong suspicion of an underlying malignant lymphoma.

In this prospective, randomized study fluconazole and amphotericin B/5-flucytosine were compared in the treatment of systemic candidiasis. Seventy-two non-neutropenic intensive care patients with systemic Candida infections were enrolled. Thirty-six patients were randomly assigned to receive fluconazole (400 mg on the first day then 200 mg) and 36 were randomized to amphotericin B/5-flucytosine (1.0-1.5 mg/kg body weight every other day and 3 x 2.5 g flucytosine/day) for 14 days following the diagnosis. There was no statistically significant difference in clinical outcome in regard to the treatment of pneumonia and sepsis: 18/28 of the patients were treated successfully with fluconazole and 17/27 with amphotericin B/5-flucytosine. For the treatment of peritonitis, however, amphotericin B/5-flucytosine was more effective than fluconazole (55% vs. 25%). Furthermore, amphotericin B/5-flucytosine was found to be superior to fluconazole with regard to pathogen eradication (86% vs. 50%). Fluconazole was associated with less toxicity than amphotericin B/5-flucytosine.

We describe congenital cutaneous candidiasis (CCC) in a term newborn. The mother had candidal vaginitis 1 week before delivery. At birth, the infant had a generalized, intensely erythematous, papulovesicular eruption, respiratory distress and elevation of liver function tests. The child responded well to intravenous amphotericin B plus topical and oral nystatin. There have been 13 previously reported cases of CCC in infants weighing more than 1500 gm who had evidence of systemic infection. Two deaths were attributed to candidal pneumonia and sepsis. The majority of infants with CCC have infection localized to the skin, but if there is any evidence of respiratory distress or signs of sepsis the possibility of systemic candidiasis and the need for parenteral antifungal therapy must be considered.

Infections are one of the major causes of morbidity and mortality during the course of systemic lupus erythematosus, and are promoted by various dysfunctions of the immune system, some of which are poorly understood. Other predisposing factors have been also identified such as the presence of glomerulonephritis and a treatment with high-dose corticosteroids or immunosuppressors. These factors have been particularly associated with the occurrence of opportunistic infections such as systemic candidiasis or Pneumocystis carinii pneumonia, whose frequency has increased with the intensity of therapeutic strategies. The most frequent infections encountered are induced by community-acquired microorganisms. Thus, initiating an empirical antibiotic treatment is justified in febrile patients with lupus erythematosus. In case of marked lymphopenia, it is recommended to start cotrimoxazole as primary prophylaxis against P. carinii pneumonia.
