Cytomegalovirus (CMV) causes major morbidity in organ transplant recipients. Gastrointestinal disease was the most prominent manifestation of CMV infection in a population of heart and heart-lung transplant patients, with an incidence of 9.9%, compared with pneumonitis (4.0%) and retinitis (0%), and occurred most frequently in CMV-seronegative recipients of organs from CMV-seropositive donors. Clinical manifestations included gastritis (nine patients), gastric ulceration (four patients), duodenitis (three patients), esophagitis (one patient), pyloric perforation (one patient), and colonic hemorrhage (one patient). Patients with gastrointestinal CMV infection were treated with intravenous ganciclovir sodium therapy, 5 mg/kg twice daily, for 2 to 8 weeks, with positive clinical, endoscopic, histologic, and virologic responses. Relapses occurred in four of nine patients who were followed up for a median period of 18 months. Retreatment resulted in healing of endoscopic lesions and in viral clearing. We conclude that early endoscopic evaluation for CMV is indicated in heart and heart-lung transplant patients with gastrointestinal symptoms. This study further suggests that intravenous ganciclovir therapy is effective for the treatment of gastrointestinal CMV in these patients.

A 12 month old boy weighing 6.4kg with esophageal varices caused by congenital biliary hypoplasia was scheduled for emergency sclerotherapy under general anesthesia. Anesthesia was induced with thiamylal sodium 3mg.kg-1 i.v. and then maintained with nitrous oxide, oxygen and a low concentration of enflurane, paralysed with pancuronium bromide. As soon as a small dose of sclerosant (5% ethanolamine oleate) was injected, transient moderate bradycardia and hypotension occurred. As his spontaneous breathing was very weak and the movements of extremities convulsive and his consciousness drowsy, prophylactic respiratory care was carried out. He had pneumonia and manifestation of DIC 4 days after sclerotherapy. He died of a massive tracheal hemorrhage. The cause of the patient's death seemed largely due to the several toxicities of sclerosant itself. We stress that although this therapy is effective for the child with portal hypertension, the incidence of complications might be high in patient with severely damaged liver function. Therefore, anesthetic and postoperative management in injection sclerotherapy should be performed very carefully.

Imipenem/cilastatin sodium (IMP/CS) was administered to patients with severe infections complicated by hematological disorders and solid tumors to assess its efficacy and safety. Primary diseases in this series of 76 cases included 37 cases of hematological disorders (acute leukemia in 25 cases, malignant lymphoma in 7 cases, aplastic anemia in 3 cases and 2 other diseases) and 38 cases of solid tumors (lung cancer in 7 cases, gastric cancer in 11 cases, esophageal cancer in 6 cases, pancreatic cancer in 3 cases, bile duct cancer in 4 cases, hepatocellular cancer in 3 cases, and 4 other diseases). Following results were obtained. 1. Types of infection in hematological diseases were sepsis in 5 cases, suspected sepsis in 24 cases, pneumonia in 5 cases and 3 others. The efficacy rates were 100% in sepsis, 62.5% in suspected sepsis, 80% in pneumonia and 73% in all cases. 2. Types of infection in solid tumors were sepsis in 2 cases, suspected sepsis in 13 cases, pneumonia in 10 cases, cholecystitis in 2 cases, cholangitis in 5 cases, liver abscess in 2 cases, and 4 others. The efficacy rates were 50% in sepsis, 69.2% in suspected sepsis, 80% in pneumonia, and 71.1% in all cases. 3. IPM/CS was administered in single use in 66 cases and in combination with other antibiotics in 9 cases. The efficacy rate in the single use was 72.7% and that in the combination use was 66.7%. 4. The efficacy rate in 35 cases of first use was 71.4% and that in 40 cases of second use was 72.5%.(ABSTRACT TRUNCATED AT 250 WORDS)

Pipemidic acid (PPA) and colistin sodium methanesulfonate (CLM) may selectively suppress aerobic gram-negative bacilli. Twenty-nine patients with acute leukemia were randomized after each course of consolidation chemotherapy to receive a single agent of nystatin (NYS) (34 courses) versus a combination of NYS, PPA and CLM (36 courses). The duration of fever over 39 degrees C was longer with the three drug combination (4.6 +/- 5.1 days) than with NYS alone (1.8 +/- 1.8 days) (P less than 0.01). Four cases of pneumonia occurred and four patients including one having pneumonia died of infection with the three drug combination, while no pneumonia or death occurred with NYS alone (P = 0.06 and P = 0.06, respectively). The combination of NYS, PPA and CLM may be less effective than NYS alone for the prevention of infection in acute leukemia patients with chemotherapy-associated granulocytopenia.

The aim of the present study was to evaluate clinical and laboratory features of acute severe asthma (ASA) in children and their outcome of mechanical ventilation (MV). Twenty ASA episodes admitted to the hospital with hypercapnia (HC) and/or lost of consciousness (LC) and/or severe non reversible bronchial obstruction (NRBO) were retrospectively studied. Long lasting asthma and frequent admissions were registered in the majority of cases. In HC group (14 cases) the PaCO2 was 70 +/- 26 mmHg (X +/- SD). Hypercapnia was associated with intravenous administration of sodium bicarbonate in three cases. In NRBO group (4 cases) the acute response to salbutamol brought out during the first week of treatment and it was associated with increased basal forced expiratory volume in one second (FEV1). Ten cases were treated with MV because of hypercapnia and/or lost of consciousness, seizures (one case), and cardiac arrest (one case). The later patient died in 24 hours. Pneumothorax and atelectasis (one case), and pneumonia (one case) were the complications of mechanical ventilation. Three cases with PaO2 less than 60 mmHg and four cases with FEV1 less than 60% were sent home. After 27 days one patient from the later group had a new episode of ASA. Arterial gases and expiratory flow measurements are paramount tools for close monitoring of children with ASA. It is suggested that normalization of those parameters are an essential criteria for discharging those patients.

Investigations of nursery outbreaks of Citrobacter diversus sepsis and meningitis have been hampered by lack of adequate epidemiologic markers for the organism. We studied outer membrane protein profiles from clinical isolates of C. diversus by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to determine whether this method might be useful in the epidemiologic differentiation of strains. Paired cerebrospinal fluid isolates from each of three separate nursery outbreaks of C. diversus meningitis, paired isolates from the vagina of a postpartum woman and the cerebrospinal fluid of her newborn infant, one isolate from an infant with pneumonia and two from colonized nursery cohorts, and 30 epidemiologically unrelated clinical isolates were included. Eleven distinct profiles were differentiated by the presence or absence of five outer membrane proteins. Complete concordance of profiles was observed for epidemiologically related isolates. Unrelated epidemic strains had outer membrane protein profiles distinct from one another. Biotyping complemented determination of outer membrane protein profiles; the two markers differentiated each of the five epidemic strains from all but one of 30 unrelated nonepidemic isolates. Determination of outer membrane protein profiles is potentially useful in epidemiologic investigations of disease caused by C. diversus.

In the period between 15/12/1987 and 15/08/1989, ten patients with either fulminating or subfulminating hepatitis have been treated by orthotopic liver transplantation (O.L.T.). Six patients are doing well in the post-operative period with a mean follow-up of 12 months (7-23 months). No evidence of neurological sequelae has been observed and recurrence of HB virus infection was absent from the three cases who survived hepatitis B transplantation. Four out these ten patients died after initial successful O.L.T... One patient succumbed 7 days after O.L.T. from sepsis or early super-acute rejection, the second 21 days after O.L.T. from neuromeningeal listeria, the third 43 days post O.L.T. from acute rejection, while the fourth developed cytomegalovirus pneumonia and died 61 days after O.L.T. Orthotopic liver transplantation has become the treatment of fulminating hepatitis. It is an emergency which is usually accompanied by successive difficulties in decision making: indication criteria, then acceptance or refusal of ABO incompatible grafts (5/10) and of suboptimal donors. Orthotopic liver transplantation for fulminating hepatitis is technically easy to perform, but usually requires the use of extra-corporal veno-venous circulation. Accompanying intensive medical care is essential and usually includes one or multiple plasmaphereses to correct existing coagulopathy without any fluid or sodium overload to the circulation.

Pharmacokinetic, bacteriological and clinical studies on imipenem/cilastatin sodium (IPM/CS) were performed in neonates. The results were as follow: 1. A total of 27 patients consisting of 17 mature and 10 immature infants were treated with IPM/CS. Each dose was 20 mg/20 mg/kg, and it was administered 2 approximately 3 times daily, in a 1-hour intravenous drip infusion for 3 approximately 12 days. The clinical efficacy of IPM/CS in 10 patients with bacterial infections (2 with sepsis, 3 with suspected sepsis, 2 with pneumonia, 2 with urinary tract infection and 1 with acute omphalitis) was evaluated as excellent in all patients, with an efficacy rate of 100%. All 5 causative organisms found in 5 patients (Staphylococcus aureus in 1, Staphylococcus epidermidis in 1, Escherichia coli in 2 and Flavobacterium meningosepticum in 1) were eradicated. Among 27 patients administered IPM/CS, adverse reactions were observed in 2 patients. These were rash and diarrhea. As for abnormal laboratory test values, elevations of GOT and GPT were observed. 2. MICs of IPM against 14 clinical isolates (S. epidermidis 1, S. aureus 6, Streptococcus agalactiae 4, E. coli 1, Enterobacter cloacae 1 and F. meningosepticum 1) from neonatal patients with bacterial infections were examined. IPM showed good antibacterial activity comparable to that of cefotaxime against S. agalactiae; however, the activity against methicillin-resistant S. aureus was poor. 3. Serum levels of IPM and CS were investigated in a total of 22 patients consisting of 15 mature and 7 immature infants after 20 mg/20 mg/kg of IPM/CS was administered. IPM and CS produced peak serum levels at the end of the drip infusion. In mature infants, peak serum levels of IPM and CS were 31.8 micrograms/ml (17.1 approximately 59.0 micrograms/ml) and 59.9 micrograms/ml (35.6 approximately 99.0 micrograms/ml), respectively. In low birth weight infants, these were 25.0 micrograms/ml (16.8 approximately 41.8 micrograms/ml) and 55.2 micrograms/ml (33.8 approximately 82.4 micrograms/ml), respectively. Half-lives of IPM and CS were 1.0 approximately 2.7 hrs. and 0.9 approximately 7.4 hrs. in mature infants, and 1.6 approximately 3.0 hrs. and 1.3 approximately 9.7 hrs. in immature infants, respectively. Generally the longer half-lives were observed in the younger neonates. Serum levels of CS remained higher and half-lives of CS were longer than those of IPM. The pharmacokinetics in neonates were different from those in adults or children.(ABSTRACT TRUNCATED AT 400 WORDS)

Pharmacokinetic, bacteriological and clinical studies on imipenem/cilastatin sodium (IPM/CS) were performed in neonates. The results obtained are summarized as follows. 1. Plasma levels and urinary excretion of IPM and CS sodium were determined in 7 neonates with ages between 7 and 26 days (gestation periods were 37 to 41 weeks and birth weights were 2,410 to 3,890 g) upon 1 hour drip intravenous infusion of IPM/CS at 10 mg/10 mg/kg, or 20 mg/20 mg/kg. Mean plasma concentrations of IPM reached their peaks at the end of infusion with levels of 12.7 +/- 3.0 micrograms/ml for the group given 10 mg/10 mg/kg, and 19.1 +/- 4.1 micrograms/ml for 20 mg/20 mg/kg. The concentration of IPM in plasma showed a dose-response to the 10 mg/10 mg/kg and 20 mg/20 mg/kg dosages. Concentrations decreased with half-lives of 1.87 +/- 0.71 hours and 1.97 +/- 0.21 hours for the low and the high dosages, and plasma levels at 8 hours after administration were 0.3 +/- 0.1 microgram/ml and 0.8 +/- 0.3 microgram/ml, respectively. Mean urinary recovery rates in 8 hours after administration were 37.6 +/- 11.8% and 26.8 +/- 17.2% for the low and the high dosages. While, mean plasma concentrations and mean urinary recovery rates of CS were higher than those of IPM, mean plasma half-lives of CS were similar to IPM. 2. IPM/CS was administered to 11 neonatal patients (with ages between 1 and 26 days) of various bacterial infections, and clinical effectiveness, bacteriological efficacy and adverse reactions were evaluated. Clinical efficacies in cases including 7 with acute pneumonia and 1 each with suspected septicemia, intrauterine infection, acute urinary tract infection and periproctal abscess were judged excellent in 10 and good in 1 case, and the efficacy rate was 100%. Causative organisms isolated from these patients included 3 strains of Escherichia coli and 1 strain each of Streptococcus pyogenes, Streptococcus agalactiae Enterococcus faecalis and Haemophilus influenzae. All the organisms were eradicated by IPM/CS, thus the bacteriological eradication rate was 100%. No adverse reactions were observed, but decreased platelet in 1 patient and increased GOT in 2 patients were found as abnormal laboratory test values. These changes, however were transient, and returned to normal after discontinuation of IPM/CS. It was concluded that the clinical results of IPM/CS are indicative of excellent efficacy, safety and usefulness of the drug in the treatment of infections in neonates.

Four strains of nutritionally variant streptococci (NVS) were isolated from the milk of mastitic cows and one strain from the lungs of a laboratory Norway rat which died from suppurative pneumonia. In primary cultivation NVS grew aerobically and anaerobically within 48-hour incubation at a temperature of 37 degrees C as minute nonhemolytic satellite colonies around a previously overlaid S. aureus strain or around other gram-positive and gram-negative bacteria. In the first subcultures NVS were growing in nutrient media enriched with 10% bovine serum and 5% staphylococcal filtrate, or 0.02% to 0.002% pyridoxal hydrochloride. All isolates did not grow in presence of 10%, 40% bile, and 6.5% of sodium chloride, neither did they grow at a temperature of 45 degrees C, they did not hydrolyze sodium hippurate, esculin, arginine, they did not produce levane and dextran from saccharose, they produced acid from mannitol, sorbitol, inulin, lactose, raffinose, trehalose, glucose, saccharose and maltose. Two strains produced acid from xylose and four strains from salicin. The strains isolated from mastitis did not have different biochemical properties from those isolated from a laboratory Norway rat with pneumonia. All strains of NVS were sensitive to chloramphenicol, ampicillin, gentamycin, lincomycin and cephalothin, four strains were sensitive to erythromycin and tyrosine, two to penicillin and one to streptomycin, oxytetracycline, chlortetracycline and novobiocin. All strains were resistant to neomycin, tetracycline, oxacillin and sulphonamides. The antigen prepared from the isolated strains by the method of Fuller did not react with any streptococcal group serum A-Z.
