Systemic candidiasis is frequently unrecognized before death of the patient because of lack of specific clinical signs, insensitive laboratory tests, and difficulties in culturing Candida albicans from the blood. Recent attention has been focused on the use of serologic testing and ocular signs to increase the rate of diagnosis of candidiasis. Because of the association between hyperalimentation fluids and disseminated candidiasis, a preliminary prospective study was carried out to determine more accurately the incidence in patients receiving hyperalimentation fluids of inapparent candida infection, candida endophthalmitis, or positive candida precipitins. Five of 23 patients developed small, white eye lesions consistent with candida endophthalmitis. Three of the five patients with eye lesions had blood cultures positive for C. albicans, and no patients without eye lesions had positive blood cultures. Candida precipitins were positive in three of the five patients with eye lesions. The results of this study suggest that unrecognized systemic candida infection may be more frequent in patients receiving hyperalimentation than previously suspected.

Untreated patients with endogenous Candida endophthalmitis who have not died of disseminated disease have required enucleation. A 57-year-old woman had endogenous Candida endophthalmitis developing subsequent to catheter sepsis during hyperalimentation, in which no antimycotic therapy was employed. The endophthalmitis resolved, and good visual acuity was preserved.

Mycotic Septicaemia (especially with the Candida species) is not an uncommon hazard of hospitalized patients, especially those on intravenous hyperalimentation. Two such patients with endogenous mycotic bilateral endophthalmitis are presented. In spite of typical ocular symptoms diagnosis was delayed. Two further unilateral cases of a more atypical form of endogenous mycotic endophthalmitis in otherwise seemingly healthy patients are also described. Correlating histopathological findings in three of these 4 cases to the clinical histories, conclusions are drawn to aid an early diagnosis which is of paramount importance if the necessary antimyotic treatment is to preserve visual function.

A case of cytomegalovirus (CMV) retinochoroiditis initially misdiagnosed as fungal endophthalmitis is reported. An 83-year-old man who was suspected of having cholangiocarcinoma presented uveitis in both eyes. Candida endophthalmitis was suspected on the basis of ophthalmic findings and past history, which included systemic corticosteroid administration and intravenous hyperalimentation. Intravenous treatment with miconazole was not effective. At autopsy, 3 months after the initial ophthalmological examination, the right eye was enucleated and examined histologically and histochemically. Light microscopic examination showed extensive retinal necrosis and numerous cytomegalic cells, so-called owl's eye cells, with intranuclear and intracytoplasmic inclusion bodies. CMV particles were seen by electron microscopy, and CMV-infected cells were observed by immunohistochemical staining by the direct method with fluorescein-labeled antibodies. These findings indicate that in suspected cases of fungal endophthalmitis various tests should also be carried out for CMV.

Early reports associated Candida parapsilosis with endocarditis in intravenous narcotic addicts. More recently, this species has emerged as an important nosocomial pathogen, with clinical manifestations including fungemia, endocarditis, endophthalmitis, septic arthritis, and peritonitis, all of which usually occur in association with invasive procedures or prosthetic devices. Outbreaks of C. parapsilosis infections have been caused by contamination of hyperalimentation solutions, intravascular pressure monitoring devices, and ophthalmic irrigating solution. Experimental studies have generally shown that C. parapsilosis is less virulent than Candida albicans or Candida tropicalis. However, characteristics of C. parapsilosis that may relate to its increasing occurrence in nosocomial settings include frequent colonization of the skin, particularly the subungual space, and an ability to proliferate in glucose-containing solutions, with a resultant increase in adherence to synthetic materials. Recently developed molecular techniques may facilitate the continued exploration of the epidemiology and pathogenesis of C. parapsilosis infections.

To determine the frequency of endogenous Candida endophthalmitis in patients with candidemia, we prospectively evaluated 32 inpatients with fungemia by weekly indirect ophthalmoscopic examinations. Chorioretinitis compatible with Candida infection was found in 9 (28%) patients. Patient age, sex, underlying diseases, or hospital-acquired factors, such as presence of central venous or Foley catheters, bacteremia, use of multiple antibiotics, hyperalimentation, or surgery, did not distinguish between groups. Groups were also similar in number of sites colonized with yeast and species of Candida recovered. Patients with endophthalmitis tended to have more blood cultures positive for Candida (mean, 4.3) than the patients without endophthalmitis (mean, 2.8), but this trend did not reach statistical significance. Based on these results, we recommend periodic ophthalmoscopic examinations in all patients with documented candidemia.

To determine the incidence of hematogenous candida endophthalmitis in seriously ill patients given parenteral hyperalimentation fluids, 131 hyperalimented postoperative patients were prospectively evaluated. All patients were screened weekly for the development of chorioretinal lesions, blood cultures positive for Candida albicans, and signs and symptoms of candida infection. Thirteen (9.9%) of 131 patients developed chorioretinal lesions compatible with hematogenous candida endophthalmitis. Seven of the 13 patients with eye lesions had blood cultures positive for yeast, whereas only two of 118 without eye lesions had blood cultures positive for yeast (P less than 0.0005). Thus, the occurrence of eye lesions consistent with hematogenous candida endophthalmitis correlated with positive blood cultures for yeast and strongly suggested invasive candidiasis.

Thirty-eight patients with fungemia were examined prospectively for development of endophthalmitis. Endophthalmitis was present in 10 of 27 (37%) patients with Candida albicans fungemia. Only one patients with nonalbicans fungemia developed endophthalmitis. Of the preselected factors studied, only hemodialysis and parenteral hyperalimentation correlated with an increased incidence of endophthalmitis. Antibody titers by latex agglutination were of little predictive value for endophthalmitis. Antigen titers by latex agglutination were performed in four cases with endophthalmitis. Antigenemia was demonstrated in three of the four patients, all of whom had negative antibody serologies. Although inconclusive, the preliminary data indicate the test may prove to be of clinical value. Periodic ophthalmoscopic examinations should be considered mandatory in the evaluation of patients with fungemia.

Two patients with acute myeloblastic leukemia are described who developed fungemia due to Trichosporon cutaneum. Fungemia occurred at the leukocyte nadir following the administration of anti-cancer chemotherapy. One patient was cured but the other died. Both patients received prednisolone continuously and had central venous catheters in place for parenteral hyperalimentation. T. cutaneum isolates were resistant to 5-fluorocytosine and moderately susceptible to fluconazole. One case was complicated by endophthalmitis due to T. cutaneum; this is the second report of such a complication in the world. We investigated the serum levels of beta-D-glucan, D-arabinitol, and Candida antigen (CAND-TEC); beta-D-glucan was elevated in both cases, which suggests that simultaneous measurements of these laboratory values are useful for the diagnosis and possibly for the evaluation of therapy for this fungal infection.

Candida sepsis is a serious and ever increasing complication in patients with a reduced defense capacity. At the intensive care unit of the infectious department in 1978-1990 from a total of 430 patients with the diagnosis of sepsis 20 (4.7%) had a Candida aetiology. Candida sepsis is suspected in particular in leukaemic patients with neutropenia, in organ transplantations and in patients given intensive care on account of a serious primary disease, bacterial infection or after surgery. The risk of deep candidosis is increased by venous catheters, hyperalimentation, antibiotic treatment, invasive operations. Diagnosis is supported by endophthalmitis and skin lesions; signs of affection of the liver, lungs, kidneys and cardiac valves are sought. Analysis of risk factors, pathogenesis and the clinical picture of invasive Candida infections is based on ample data in the literature.
