Since serious infections are major complications in patients with fewer than 200 phagocytic cells per microliter or in patients with dysfunctional phagocytes, granulocyte transfusions have been used in an attempt to improve clinical outcome. After two decades of trial and clinical use, the role of granulocyte transfusions for therapy of serious infections has not been clearly established. The methods of harvest, storage, and transfusion of granulocytes are acceptable; however, the quantities that are obtained from donors restrict numbers of cells that may be transfused. Limited clinical response has diminished enthusiasm for the use of granulocyte transfusions as therapy, and their use as prophylaxis has been ineffective. Reported clinical data suggest that patients with persisting granulocytopenia with sepsis due to gram-negative bacteria and patients with chronic granulomatous disease with life-threatening infections unresponsive to aggressive antimicrobial therapy may benefit from granulocyte transfusions.

Thirty-two patients with Stage III or IV epithelial ovarian cancer and residual tumor volumes in excess of 2 cm in diameter after initial debulking were treated with platinum and cyclophosphamide chemotherapy. Twenty-seven patients (84%) received at least six courses of chemotherapy. Six patients developed grade 3 or 4 hematologic toxicity and one patient died with granulocytopenia and sepsis. The actuarial survival of the total group of patients was 78% at 12 months, 27% at 24 months, and 11% at 36 month. Of patients with residual disease 2-4 cm in diameter, 82% were alive 12 months after diagnosis and 46% were alive at 24 months. In contrast, patients with greater than 4 cm residual disease had a 12-month survival of 73% and a 24-month survival of only 7%. The size of residual tumor after surgery remains a very important prognostic factor in patients treated with platinum-based combination chemotherapy. Reoperation with further tumor debulking should be considered in ovarian cancer patients referred for chemotherapy with large volume residual disease to maximize response to combination chemotherapy.

Sixteen patients with advanced evaluable urothelial cancer were treated with a chemotherapy regimen of cyclophosphamide, adriamycin and cisplatin (CAP). Cisplatin 50 mg/m2 and adriamycin 30 mg/m2 were given on the first day and cyclophosphamide 200 mg/m2 was given from the second to the fifth day. This course was repeated every 3 weeks. The objective response rate was 25% (4 of 16 patients), with 1 patient achieving complete remission. The survival time of responders was longer than that of nonresponders, although the difference was not significant (generalized Wilcoxon method). As side effects, nausea with vomiting (43.8%), renal dysfunction (6.3%), anemia (12.5%), leucopenia (12.5%), thrombocytopenia (25.0%), alopecia (68.8%), heart failure (6.3%) and peripheral neuropathy (6.3%) were noticed. One patient died of sepsis due to agranulocytosis and another died suddenly of heart failure.

Ninety-one episodes of polymicrobial bacteremia and fungemia were compared with 407 unimicrobial episodes to assess differences in the microbiological, epidemiological, and clinical features of the two syndromes. Enterobacteriaceae, nongroup A streptococci, anaerobic bacteria, and pseudomonads were disproportionately common in polymicrobial bacteremia. Polymicrobial episodes were significantly more likely to be hospital-acquired, to emanate from bowel or multiple foci, and to occur in patients with nonhematologic malignancies or multiple underlying diseases. Deaths directly related to sepsis were twofold higher in polymicrobial versus unimicrobial bacteremia. Factors associated with increased mortality in polymicrobial sepsis included age greater than 40 yr; absent or diminished febrile response to sepsis; absolute granulocytopenia; inadequate antimicrobial therapy for all microorganisms isolated; and a primary focus of infection in the bowel, the respiratory tract, an abscess, or an occult site. The occurrence and type of polymicrobial bacteremia can suggest a source of sepsis as well as additional diagnostic and therapeutic maneuvers.

Granulocytopenia and oral mucosal defects have been reported to be important predisposing factors to recently recognized cases of Capnocytophaga septicemia. The authors call attention to an apparent preponderance of these cases in the pediatric age group and emphasize laboratory features which they have found helpful in the diagnosis of Capnocytophaga infections. Thirteen patients with Capnocytophaga infections were seen during a seven-year period. Seven of these patients had Capnocytophaga bacteremia. Six of seven bacteremic patients were granulocytopenic, six had oral mucosal defects, and three died. Five of the seven bacteremic patients were younger than 20 years of age. This represents a disproportionate distribution of cases in the pediatric age group within the author's institution, because 43% of blood culture specimens submitted to their microbiology laboratory are obtained from pediatric patients. This observation is supported by a review of the reported cases of Capnocytophaga septicemia in which 7 of 12 patients were younger than 20 years of age. Because Capnocytophaga may superficially resemble the more commonly isolated Fusobacterium nucleatum, distinguishing features for laboratory identification are discussed.

Candida krusei colonized 12.4% of 868 patients undergoing episodes of therapy-induced granulocytopenia over a 9-year period. The gastrointestinal tract was most frequently colonized, followed by the respiratory tract and urinary tract. Ten patients developed systemic infections with C. krusei; all 10 had two or more positive blood cultures. Nine of the 10 patients were colonized with C. krusei, and 6 were receiving systemic antifungal agents at the time of development of the infection. Seven patients died within 1 month of C. krusei sepsis; systemic candidiasis was seen in the autopsies of the four patients on whom autopsies were performed. Therefore, C. krusei should be recognized as an emerging pathogen in select patient populations.

The peak and trough levels of bactericidal activity of the serum of 74 severely granulocytopenic patients (less than or equal to 500 polymorphonucleates per microliter) with hematologic malignancies and Gram-negative septicemia were measured using the patient's infectious organism and serum containing the given antibiotics. When the peak titer of bactericidal activity in the serum was greater than 1:8 the septicemia was cured in more than 90% of the cases. However, in order to achieve a satisfactory rate of cure, patients with less than 100 polymorphonucleates/microliter required higher peak levels than patients with 100-500 polymorphonucleates/microliter. Serum bactericidal activity was influenced by the in vitro susceptibility of the offending pathogen and by the presence of in vitro synergism between the given antibiotics. These two variables showed a correlation with the clinical outcome that proved to be increasing with the degree of granulocytopenia. Furthermore, synergistic combination of the antibiotics appeared essential when the in vitro susceptibility shown by the offending pathogen was moderate. These data suggest (i) that determination of the bactericidal activity of the serum may prove to be a useful method to predict the clinical outcome in severely granulocytopenic patients with Gram-negative septicemia; and (ii) under the same conditions, antibiotic combinations that have demonstrable in vitro synergy against the offending pathogen should be given the utmost consideration.

Intracellular metabolite glutathione, existing in either its reduced (GSH) or oxidized states, is crucial for the protection of any cell against an oxidative stress or injury. Significant depletion of intracellular levels of GSH predisposes cells to an oxidative injury. We have investigated the level of hepatic GSH during the early course of sepsis in a physiologically well-characterized septic-sheep model. Following six hours of sepsis, which was characterized by hypotension, hypoxemia, and granulocytopenia, the level of intrahepatic GSH was significantly reduced compared with baseline levels. There was no reduction after two hours of sepsis. Hepatic GSH levels in control animals were unchanged compared with baseline levels. These findings suggest that the liver may be more susceptible to an oxidative stress in septic patients.

Cefotaxime (CTX) was administered to 117 pediatric patients. Although 26 of these patients were excluded from the clinical evaluation of the study because other antimicrobial agents were given concomitantly with CTX or because no infectious diseases were proved, these cases were evaluated for adverse effects of the drug. The remaining 91 cases were evaluated for clinical effect; pneumonia in 56 cases, septicemia in 5, suspected septicemia in 5, meningitis (aseptic cases included) in 3, urinary tract infection in 5 and other diseases in 17. No pathogenic organisms were identified in any of the pneumonia cases, even either by bacterial culture or other laboratory test methods. Pathogens of septicemia were E. coli in 3 cases, K. pneumoniae in 1 and E. agglomerans in 1. Those of urinary tract infections were E. coli in 3 cases, a mixed infection of S. aureus and an unidentified species of Gram-negative rods in 1, and unknown in 1. Clinical effectiveness rates of CTX were 78.6% in pneumonia and 100% in septicemia, suspected septicemia and urinary tract infections. One patient with purulent meningitis caused by H. influenzae was also treated with CTX successfully. Adverse reactions and abnormal laboratory findings were observed in 12 cases (12/117 = 10.3%); rash in 2 cases, vomiting in 1, abdominal pain in 1, diarrhea in 5, granulocytopenia and thrombocytopenia in 1, eosinophilia in 3 and elevation of liver enzymes (GOT and LDH) in 1.
