Ileostomy function was studied in 12 patients with an established ileostomy following proctocolectomy, in 6 of whom minimal amounts (less than 9 cm) and in 6 significant amounts (30-120 cm, mean 60 cm) of terminal ileum had been removed. Patients who had undergone significant ileal resection had daily faecal volumes considerably greater than those with minimal ileal resection (1202 +/- 284 ml versus 401 +/- 92 ml, P less than 0.001), and also greater daily outputs of sodium (146 +/- 53 mEq versus 43 +/- 12 mEq) and potassium (12.7 +/- 9.0 mEq versus 4.0 +/- 0.99 mEq). The percentage water content of the ileostomy fluid was greater in patients who had had the ileum resected (93.1 +/- 1.8% versus 89.8 +/- 2.5%). In addition, the sodium/potassium ratio in the urine in patients with a properly acting ileostomy after ileal resection was low. It is concluded that when recurrent inflammatory bowel disease, partial small bowel obstruction and intraperitoneal sepsis have been excluded there remains a number of patients whose high ileostomy output is due entirely to the amount of ileum resected. The management of patients with a high output ileostomy with codeine phosphate, Lomotil and oral administration of sodium chloride tablets is discussed.

In a retrospective study covering the period January 1972 to June 1974, recovery rates of bacteria and of fungi were generally equivalent with tryptic soy broth, Thiol, thioglycolate, and Columbia broth media (all under vacuum with carbon dioxide and sodium polyanetholesulfonate). An additional biphasic medium consisting of brain heart infusion broth and a brain heart infusion agar slant, which was inoculated only where fungal sepsis was suspected clinically, yielded significantly higher recovery rates of fungi. There were 29 instances of cultures with fungi in both the biphasic and broth media, 80 instances of cultures with fungi only in the biphasic medium, and no instances of fungi only in the broth media. The isolates were as follows: Candida albicans, 74; C. parapsilosis, 20; C. tropicalis, 16; Torulopsis glabrata, 18; Torulopsis sp., 1; Cryptococcus neoformans, 12; C. laurentii, 2; and Histoplasma capsulatum, 16. Despite routine subcultures of the broth media to chocolate blood agar within 24 h of inoculation and after 5 days of incubation, detection of fungemia was significantly improved by the use of a biphasic medium.

Furosemide frequently is advocated as a prophylaxis against renal failure in septic and injured patients; this effect is thought to be secondary to an increase in renal blood flow. This postulate was tested within 72 hours of admission in 22 previously healthy patients with acute pancreatitis (two), massive trauma (ten), or severe sepsis (ten). Renal clearances of inulin (GFR), para-amino hippurate (ERPF), sodium (CNA), osmoles (COsm), and free water (CH2O) were measured in milliliters per minute before and after the intravenous infusion of furosemide (0.5 mg. per kilogram of body weight). Renal vein PAH levels (EPAH) in eight patients were used to calculate true renal plasma flow (TRPF), true renal blood flow (TRBF), and renal vascular resistance (RVR). Furosemide caused a significant increase in urine volume, CNa, and COsm; there were no significant changes in GFR, ERPF, RVR, TRBF, and EPAH. These findings also were observed when the patients were subgrouped according to elevated, normal, or low renal plasma flow and elevated renal vascular resistance. No significant changes were seen in EPAH, thus making a redistribution of renal blood flow unlikely. These studies indicate that furosemide has only a diuretic effect and no hemodynamic effect in the kidney; it has the potential of seriously reducing the circulatory volume and causing renal failure in critical patients.

The protease inhibitor aprotinin was given a) in experimental septic shock, and b) in patients with hepatic cirrhosis and ascites, since in both conditions, activation of the plasma kallikrein-kinin system is associated with pathological systemic vasodilatation, which may trigger reflex neuroendocrine activation and renal solute retention. Given early in experimental sepsis, aprotinin maintained the arterial pressure, systemic vascular resistance (SVR), creatinine clearance and sodium excretion, all of which fell in controls. Aprotinin also blocked increases in pulmonary artery pressure and plasma renin activity (PRA). Given late in sepsis, aprotinin caused a rapid rise in arterial pressure and SVR towards baseline levels. In cirrhosis, aprotinin increased SVR in patients with low baseline values, and improved glomerular filtration rate, renal plasma flow and sodium excretion in all subjects; PRA was suppressed by aprotinin. Aprotinin reverses pathological systemic vasodilatation in these two conditions, and this is associated with a reduction in renin release and improved renal function.

The effects of sepsis on intracellular Na+ activity, Na+ concentration, and H2O partition in skeletal muscle were investigated in a burn rat model. Studies were performed on either postburn day 3 or day 7 during evolving burn wound sepsis. Data are compared among 3 groups of rats: burned and infected (BI), burned not infected (B), and sham burn (C). After 3 days postburn both Na+ activity and concentration decreased in the BI group as compared with B and C groups. By postburn day 7, the BI group developed septic shock and had increased intracellular Na+ activity and concentration. The resting membrane potentials of skeletal muscle cells depolarized. The finding of an increased cell membrane relative permeability of Na+ to K+ could account for the increase in Na+ influx into cells. In addition, intracellular and total muscle H2O contents decreased and extracellular H2O increased. Hypernatremia, hyperchloremia, and hyperosmolality were also observed in the BI group. However, the fact that there was no significant difference between B and C groups indicates that the late derangements were due to septic shock rather than simple burn injury. Thus, the deleterious effects of the evolving burn wound sepsis on Na+ homeostasis might be due to the detrimental effect of increased intracellular Na+ activity on mitochondrial respiratory control with subsequent impairment of cellular functions.

Excessive hydrogen peroxide (H2O2) generation appears to contribute to the development of the adult respiratory distress syndrome (ARDS), but H2O2-combatting antioxidant defenses have not been evaluated. We found that serum from septic patients with ARDS scavenged more (p less than 0.05) H2O2 in vitro (82.7 +/- 3.8%) than did serum from septic patients without ARDS (56.9 +/- 3.1%) or control subjects (20.2 +/- 2.4%). Serum from septic patients with ARDS also had more (p less than 0.05) catalase activity (54.9 +/- 10.9 U/ml) than did serum from septic patients without ARDS (28.6 +/- 3.4 U/ml) or control subjects (7.3 +/- 0.8 U/ml). In contrast, serum from septic patients with or without ARDS and control subjects had the same glutathione peroxidase (GPX) activity. Serum H2O2 scavenging activity correlated with serum catalase (r = 0.77) but not GPX (r = 0.33) activity and was inhibitable (greater than 90%) by sodium azide, a catalase inhibitor. Increases in serum catalase activity did not appear to be derived from erythrocytes (RBC) because septic patients with or without ARDS and control subjects had similar RBC hemolysis in response to osmotic stress in vitro and serum haptoglobin concentrations. Serum from septic patients with ARDS also protected endothelial cells against H2O2-mediated damage (34.5 +/- 2.2% 51Cr release) better (p less than 0.05) than serum from septic patients without ARDS (47.3 +/- 7.4%) or control subjects (82.1 +/- 10.2%), but killing of bacteria by neutrophils in vitro was the same in serum from patients and control subjects. Our findings indicate that patients with sepsis and/or ARDS have increased serum catalase activity, which may alter H2O2-dependent processes.

Eighteen immuno-compromised children (malignancies, hematological diseases, collagen diseases) with neutropenia and infections were treated with imipenem/cilastatin sodium (IPM/CS), and the efficacy and the safety of the drug were evaluated. 1. Responses to IPM/CS were excellent in 13 patients, good in 1, and fair in 4. None of the patients displayed a poor response to the treatment thus the efficacy rate was 77.8%. 2. Of 5 patients with sepsis, 4 had excellent or good responses. IPM/CS was effective against sepsis caused by Enterococcus faecalis and Pseudomonas aeruginosa. 3. In patients with severe neutropenia (WBC less than 100/mm3), the efficacy rate was 70%. 4. As for side effects, elevations of GOT and GPT were observed in 1 patient with liver cirrhosis. These results indicate that IPM/CS is safe and effective in immuno-compromised children with neutropenia and infections.

Group B streptococci (GBS) cause the majority of cases of neonatal sepsis and meningitis in the United States. Immunization of women of childbearing age is one strategy under consideration for the prevention of neonatal disease. The beta C protein, a 130-kDa antigen present in many clinical isolates of GBS, was purified from GBS by extraction into sodium dodecyl sulfate (SDS)-containing buffer, preparative SDS-polyacrylamide gel electrophoresis, and electroelution. Purified beta C protein antigen (25 micrograms) with Freund's adjuvant was used to immunize rabbits. Rabbits developed enzyme-linked immunosorbent assay titers of > 1:1.6 x 10(6), and sera from immunized rabbits were administered to pregnant mice. Their neonatal pups were then challenged with a strain of GBS expressing beta C protein; 68% of these pups were protected by immune antiserum, whereas no controls were protected (P < 0.001). The immune serum (diluted 1:100) facilitated opsonophagocytic killing of GBS strains expressing the beta C protein but not those that do not express the antigen (mean log kill +/- standard deviation = 0.71 +/- 0.8 log10 CFU for beta+ strains and 0.09 +/- 0.2 for beta- strains; P = 0.02). In subsequent experiments, adult female mice were actively immunized with two doses of 2, 5, or 10 micrograms of beta C protein 2 months prior to mating. One- to two-day-old offspring of these dams were challenged with GBS and were protected in a dose-dependent manner, with 96% survival in the high-dose (10-micrograms) group and 20% survival in a sham-immunized control group (P < 0.001). Thus, active immunization of mice with the GBS beta C protein confers protection against lethal infection with beta+ GBS to their offspring.

The medical records of 12 horses with septic arthritis of a distal interphalangeal joint were reviewed to determine clinical features and response to treatment. Sepsis was caused by trauma or an injection that resulted in an open or contaminated distal interphalangeal joint. All horses were severely lame. Treatment included broad-spectrum parenterally administered antimicrobial drugs (ten horses), percutaneous through-and-through joint lavage (eight horses), indwelling drains (three horses), immobilization of the limb in a cast (three horses), intraarticular injection of sodium hyaluronate (one horse), intraarticular injection of antimicrobial drugs (five horses), curettage of the distal phalanx (one horse), and cancellous bone grafting to promote fusion (one horse). Five horses were euthanatized. Ankylosis of the affected joint developed in five horses, four of which are pasture sound. Two horses treated medically are sound although one underwent subsequent palmar digital neurectomy for treatment of navicular syndrome.

Thirty patients with relapsed pediatric solid tumors received high-dose carboplatin and etoposide with autologous marrow support in a dose-escalation trial. These patients had received extensive prior treatment, which included both cisplatin and etoposide in 25 cases. Six patient cohorts received carboplatin in doses of 1200-2100 mg/m2 and etoposide in doses of 960-1500 mg/m2. All courses were associated with severe neutropenia and thrombocytopenia. The median times from bone marrow infusion to granulocyte recovery (> 0.5 x 10(9)/l) and platelet recovery (> 50 x 10(9)/l) were 33 and 28 days, respectively, with similar findings for all dosage levels. The frequency of non-hematologic toxicities was generally low, although hyponatremia (Na+ < 129 mEq/l) was seen in one-third of the courses. Hepatoxicity was dose-limiting and was significantly associated with the cumulative prior cisplatin dose (p = 0.006). There were four toxic deaths (CNS hemorrhage, alfa-streptococcal sepsis, Candida sepsis, and enterocolitis). Eleven patients received a second course of therapy; toxicity profiles and times to hematologic recovery were similar for the two courses. Clinical responses were observed at all dosage levels. Eleven of 26 evaluable patients achieved a clinical response (one complete, 10 partial). The majority of responses were in patients with neuroblastoma (six of 16) or Hodgkin's disease (two of three). For phase II clinical trials, we recommend dosages of 2100 mg/m2 of carboplatin and 1500 mg/m2 of etoposide for children with prior cumulative cisplatin exposure < 960 mg/m2. This carboplatin dose represents a three- to four-fold increase over pediatric doses tolerated without bone marrow support.
