The problem of fungus infections after liver transplantation was studied. In 100 consecutive recipients of orthotopic liver homografts there were 10 and 8 examples, respectively, of localized and disseminated infections caused by Candida species. Candidemia was demonstrated in 8 of these 18 patients. One patient who had a localized Candida infection also had disseminated cryptococcosis. An additional 31 patients were infested in that Candida could be cultured from sites where it is not normally found, such as the blood (8 examples), urine (8), ascitic fluid (8), and wounds (22). This exorbitant incidence of monilial infections and infestations was associated with a high frequency of complications involving the homograft as well as the hosts' gastrointestinal tract during the post-transplantation period. The yeasts found in blood, urine, ascitic fluid and elsewhere were thought to have originated from the gut. Ten of the 100 patients had aspergillosis which was localized in 7 instances and disseminated in 3. The lung was the most frequently affected organ. The fungus infections played a contributory role in the downhill course of our patients but in the event of death more fundamental and more frequent causes of failure were technical complications involving the homografts, difficulties in controlling rejection with reasonable immunosuppressive doses and bacterial sepsis. Suggestions have been made for the better control of fungal infections in liver recipients.

The role of complement in experimental disseminated candidiasis was studied in normal guinea pigs, animals congenitally deficient in the fourth component of complement (C4), and animals depleted of alternative pathway activity by cobra venom factor (CVF). Animals pretreated with CVF and challenged with Candida albicans had a high rate of mortality. Results of quantitative organ cultures corroborated prior reports that the kidney was the major target organ of infection. Infection of the kidney was markedly enhanced by CVF-induced depletion of the alternative pathway but not by classical pathway deficiency (deficiency in C4). There were differences among organs (kidney, liver, and spleen) in their requirement for complement to mount an effective host defense response. Ultimately, the integrity of the alternative pathway and late components of complement appears necessary for the limitation of and survival from sepsis due to C. albicans in nonimmune animals.

Fungus balls of the urinary tract are rare and usually associated with infection by Candid albicans. Since 1968 five patients seen at the Medical College of Virginia Hospitals presented with this peculiar manifestation of candidiasis. Summaries of their epidemiologic clinical, pathologic, and mycologic data are presented. All Candida fungus balls involved the upper collecting system and were detected by radiography and confirmed by culture and/or pathologic section. Two of the five patients completely recovered. Three patients were treated with flucytosine and/or local irrigation with a polyene antifungal agent. Two recovered and the third died of probable bacterial sepsis. One patient was treated successfully with surgical removal of the fungus ball and a brief period of local irrigation with amphotericin B (AMB). The fifth patient recovered after 28 days of parenteral AMB. Predisposing factors and pathogenetic mechanisms are discussed, and a rational approach to therapy is outlined.

Eighteen patients with primary abnormalities of neutrophil chemotaxis are described. The most common clinical presentation was one of recurrent upper respiratory tract infection (nine patients) or recurrent pyoderma (seven patients), and two children had a history of oropharyngeal candidiasis and recurrent skin sepsis. Of these eighteen patients, sixteen had intrinsic polymorphonuclear leucocyte (PMN) defects as shown by diminished random migration and movement towards endotoxin-activated serum. PMN chemotaxis towards casein was, however, normal. In nine out of the latter patients, there was an associated inability of the serum to generate chemotactic factors. PMN from two adult patients, both suffering from recurrent boils, moved normally both in random and directed systems, but sera from these patients contained heat-stable inhibitors of neutrophil chemotaxis. In vitro levamisole treatment (10(-3) M) markedly improved the PMN function. When patients were treated with levamisole, however, no clinical response was noted, although PMN movement improved in a number of cases.

In a review of 2,616 consecutive autopsies done at the University of Kentucky Medical Center over a 12-year period, 46 patients with complete postmortem examinations had tissue-verified candidiasis in two distinct patterns, with Candida albicans being most frequently cultured. Superficial candidiasis involving only lining surfaces was observed in 21 patients (46%). Usually, it complicated other lethal problems such as malignancy and bacterial sepsis. Nineteen of these patients (95%) had received antibiotics. No vessel invasion or deep organ involvement was evident in this group. The other pattern of candidiasis was a deep or systemic variety recognized in the remaining 25 patients (54%). It was characterized by deep parenchymal organ lesions usually involving the brain (52%), heart (48%), and kidney (80%), but any tissue seemed susceptible. Vessel invasion was seen in 8 patients (32%); intravenous lines were used in 13 (52%); and major operations were done in 16 (64%). All these patients were hospitalized for either benign or malignant conditions and were treated for bacterial sepsis with antibiotics for seven days or more. This investigation indicates that candidiasis occurs when the host's environment is altered primarily by antibiotic therapy. Candida then can colonize lining surfaces and from there could invade adjacent vessels and disseminate throughout the body.

During a 14 month period there were 364 episodes of bacteremia and fungemia at Memorial Sloan-Kettering Cancer Center. The first nine months of the study were retrospective, and the next five prospective. In patients with leukemia or lymphoma (group 1), Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus were the most frequently isolated organisms. The mortality in this group was 40.5 per cent. In the patients with solid tumor (group 2), Esch. coli, Staph. aureus, Bacteroides sp. and Candida sp. were most frequent. Mortality was 27.8 per cent. The source of infection in both groups was often indeterminate. High mortality was associated with pulmonary and intraabdominal infection and with Ps. aeruginosa, K. pneumoniae or polymicrobic sepsis. Factors of prognostic significance were the causative microorganism, source of infection and shock. Although mortality was higher in patients with leukopenia than in those with normal leukocyte counts, the differences were not significant. The mortality in this series was low considering the severity of the underlying diseases and the immunosuppressed state of many of the patients. In a prospective, randomly controlled study, mortality was further diminished by infectious disease consultation at the time the positive blood culture was reported. Severe fungal superinfection, predominantly aspergillosis and candidiasis, was found in 52 per cent of the autopsy patients with leukemia or lymphoma (group 1), but in only 8 per cent of those with solid tumors (group 2).

Both surgical trauma and infection can disturb the proteinase to proteinase inhibitor balance in the circulation. We sought to assess the effect of Candida albicans infection (INFX) on postoperative mortality, to correlate mortality with total serum proteolytic activity (PA), and to assess the impact of exogenous proteinase inhibitors (PI) on this mortality. Mice underwent midline laparotomy (LAP) and immediate postoperative intravenous C. albicans infection. LAP + INFX shortened mean survival compared to INFX or LAP alone. Quantitative renal cultures confirmed that death in the LAP + INFX and INFX groups was due to Candida sepsis. PA was measured using an 125I-labeled protein assay, yielding micrograms of acid-soluble peptides/100 microliters of serum. In control, sham-operated, and LAP groups, PA averaged less than 9.0, and mortality was 0. In INFX and LAP + INFX groups, PA averaged greater than 14.5 and mortality was high. To determine if high PA was related to high mortality, LAP + INFX mice were treated immediately preoperatively with a single dose of PI (1 mg alpha 1-proteinase inhibitor, 1 mg antithrombin, and 1000 KIU aprotinin). Mean survival increased with PI treatment. In conclusion, the addition of Candida infection to surgical trauma hastened mean time to death. More rapid death correlated with elevated PA and may reflect systemic imbalance in the proteinase to proteinase inhibitor ratio in the circulation. PI improved survival, suggesting that proteinase inhibition may prove useful in the future in the treatment of fungal sepsis in surgical patients.

During 1983-1988, hospitalizations of patients with a diagnosis of human immunodeficiency virus (HIV) infection increased from 1.3 to 33.7 per 100,000 persons. We used the National Hospital Discharge Survey, which is based on a representative sample of discharges from nonfederal short-stay hospitals, to describe illnesses among hospitalized patients with HIV infection. Of 222,200 such hospitalizations during 1983-1988, most occurred among persons who were 25-44 years of age (79%), white (66%), and male (90%). Among men 25-44 years of age, HIV admissions increased from 8.5 to 148.6 per 100,000 persons during 1983-1988; among black men 25-44 years of age, HIV hospitalizations increased from 43.1 to 387.4 per 100,000 persons. Among women, hospitalizations increased 3.4-fold. Frequently listed illnesses in the Centers for Disease Control (CDC) AIDS case definition were Pneumocystis carinii pneumonia (30%), candidiasis (20%), and Kaposi's sarcoma (13%). Other frequently listed illnesses included infections (39%) such as pneumonia, sepsis, and urinary tract infections; blood dyscrasias (30%) such as anemia, thrombocytopenia, and agranulocytosis; metabolic (17%), gastrointestinal (16%), and respiratory disorders (12%); and drug abuse (9%). These data provide a minimum estimate of HIV hospitalizations because for some patients HIV infection may not be specified on the discharge record. HIV hospitalizations are increasing markedly and are associated with a broad spectrum of severe morbidity.

Forty-five cases of systemic neonatal candidiasis were diagnosed over a 9-year period in a neonatal intensive care unit; 42 infants weighted less than 1.5 kg. All had been very ill with preceding bacterial sepsis and other complications of low birthweight. Where treatment was instituted the mortality was low (4 out of 39 dying) and complications of treatment were transitory. We therefore recommend diligent examination for the presence of this infection, and treatment with a combination of amphotericin B and 5-flucytosine.

Seventy three adults underwent orthotopic liver transplantations between February 1987 and November 1989 and were followed (54 retrospectively and 19 in a prospective study) with the aim of establishing the incidence of deep mycoses (3 disseminated candidiasis due to C. albicans, 1 invasive aspergillosis due to A. fumigatus and 1 invasive pulmonary aspergillosis due to A. niger and A. fumigatus). 4/5 of these infections occurred in the first month after transplantation. All the patients were associated with the following clinical risk factors: previous use of wide spectrum antibiotics (5/5); more than 1 abdominal laparotomy (4/5), due to primary failure of the graft (3/4) and thrombosis of the hepatic artery (1/4). Two of the three patients [corrected] with invasive candidiasis had previous episodes of documented fungemia. 24 patients of the group who didn't show MIP had some risk factor which in all of them was the previous use of high dose steroids and/or of wide spectrum antibiotics, in addition to the used in surgical prophylaxis. In our series, the one risk factor associated with MIP was more than one previous laparotomy (p less than 0.001). Other significant associated infections were 3 bacterial sepsis (2 due to Enterococcus faecalis and 1 due to Staphylococcus epidermidis) and one viral (Cytomegalovirus viremia). The mortality rate was 100%, however the cause of death was multifactorial.
