With improvements in surgical techniques and management of postoperative complications, heart transplantation can now be performed with donors and recipients who were previously considered unsuitable. In this study, we report the results of heart transplantation with marginal donors and recipients in our hospital. From June 1993 through June 1998, we performed 79 heart transplantations. Marginal recipients were defined as those with high pulmonary vascular resistance (> 6 Wood units), severe renal impairment (serum creatinine > 2 mg/dL and creatinine clearance < 50 mL/min), or severe hepatic dysfunction (ALT and AST > 100 IU/L or serum bilirubin > 2.5 mg/dL). Marginal donors were those with any of the following conditions: old age (> 40 years), size mismatch (donor/recipient body weight ratio < 0.8), history of chronic alcohol use, previous cardiopulmonary resuscitation and hypotension, hepatitis B or C virus positivity, coronary artery disease, high-dose dopamine (> 10 micrograms.kg-1.min-1), or prolonged allograft ischemic time (> 4 hours). Of the 79 transplantations performed, 45 (58%) involved marginal recipients or donors. The 30-day mortality rate was 5%, and the 1-year and 5-year survival rates were 87% and 83%, respectively. The survival rates did not differ significantly between cases involving marginal donors or recipients and those involving nonmarginal donors and recipients. There were 27 marginal recipients (34%), only one of whom died during surgery. Five of six recipients with severe renal impairment needed short-term hemodialysis after transplantation. Recipients with high pulmonary vascular resistance had a higher incidence of early acute rejection (5/10 vs 22/69). Thirty-three (42%) of the patients received transplants from marginal donors, four of whom died during surgery; two died of acute vascular rejection, one of allograft failure caused by prolonged ischemic time, and one of bleeding secondary to preoperative sepsis and coagulopathy. These results show that heart transplantation may be performed in marginal recipients and donors, with acceptable operative mortality.

The clinical usefulness of injectable biapenem (BIPM) was examined for various infectious diseases in the fields of internal medicine, urology, surgery, orthopedics, obstetrics and gynecology, otorhinolaryngology, ophthalmology, dermatology, oral surgery, and plastic surgery. BIPM was administered by intravenous drip infusion at a dose of 150, 300, or 600 mg twice a day. The concentrations in various body fluid and tissues were also examined. 1. In the total enrollment of 256 cases, the numbers subjected to the analyses for clinical efficacy, bacteriological efficacy, side effects and abnormal laboratory findings were 214, 170, 252 and 251 cases, respectively. 2. The clinical efficacy rate was 85.5% (183/214 cases) as a whole, being 2/2 for sepsis, 6/8 for cellulitis and lymphangitis, 76.2% (16/21) for traumatic, operative wound and burn infections, 4/6 for osteomyelitis and arthritis, 92.9% (13/14) for peritonsillar abscess and peritonsillitis, 83.3% (15/18) for chronic lower respiratory tract infection, 7/7 for pneumonia, 83.3% (30/36) for complicated urinary tract infection, 100% (14/14) for cholecystitis and cholangitis, 88.2% (15/17) for peritonitis, 86.5% (32/37) for internal genital infection, 8/9 for pelvic peritonitis, 2/4 for corneal ulcer, orbital infection and panophthalmitis, 1/2 for otitis media, 4/4 for sinustitis, 93.3% (14/15) for osteitis of jaw and cellulitis of mouth floor. The efficacy rate in the poor responders to the pretreatment by other antibiotics was 86.4% (70/81). 3. 300 strains of causative organisms were isolated from 170 cases which contained polymicrobial infections. The elimination rate of causative organisms was 85.3% (256/300 strains), in terms of bacteriological efficacy. 4. Side effects were noted in 11 of 252 cases (4.4%) with 11 events. The signs and symptoms were the skin symptoms (5 cases), gastro-intestinal symptoms (3 cases), interstitial pneumonia (2 cases), and feeling bad (1 case), all of which disappeared during treatment or after the discontinuation of treatment. The abnormal laboratory findings were observed in 31 of 251 cases (12.4%) with 50 events, and major ones were an increase in eosinophils, and elevations of AST, ALT, gamma-GTP and Al-p. 5. The concentrations of BIPM in body fluid and tissues were determined in 46 cases (212 samples) most of which were administered 300 mg of BIPM by intravenous drip infusion for 60 minutes. The concentrations in the sputum within 6 hours after administration were 0.1-2.5 micrograms/g. The maximum concentrations in body fluid and tissues were 0.2-1.8 micrograms/g or ml in the bile, middle ear mucosa, tonsillar tissue, aqueous humor and bone tissues and were 2.0-5.7 micrograms/g or ml in the gallbladder, maxillary sinus mucous membrane, ethmoidal sinus mucous membrane, oral tissues, skin, woman genitals, synovia, joint tissue, and the eschar. The concentrations in the uterine arterial plasma and retroperitoneal fluid were almost similar to those in the cubitl vein plasma. From the above-mentioned results of clinical efficacy, bacteriological efficacy, and safety, injectable BIPM was confirmed to be useful in the treatment of moderate, severe and/or refractory infections in various fields.

The aim of this study was to monitor hepatic function in patients with pneumonia meeting the sepsis criteria of the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) and to determine if hepatic dysfunction is related to the systemic inflammatory response. Twenty patients were recruited. The monoethylglycinexylidide (MEGX) test was carried out on days 1-10 after admittance to the intensive care unit. Blood samples for determination of serum concentrations of hyaluronic acid, C-reactive protein (CRP), interleukin (IL)-6, IL-8, IL-10 and conventional liver function tests (aspartate aminotransferase, alanine aminotransferase, bilirubin, albumin) were also drawn. Patients were classified into two groups according to illness severity estimated by the simplified acute physiology score (SAPS II) on the day of admission. Patients in group I (n=10) had a SAPS II probability of mortality >3% while those in group II (n=10) had a SAPS II < 3%. The MEGX level over the first five days was significantly lower in group I than in group II (p<0.0001). Significant inverse correlations during the first 5 days were observed between the MEGX 30 min test results and IL-6, CRP and SAPS II and more modest correlations with hyaluronic acid (p=0.0025) and IL-10 (p=0.021). The conventional liver function tests did not differ between the two groups and were mostly within the respective reference ranges. We conclude that the MEGX test is a sensitive marker of liver dysfunction early in sepsis and that low MEGX values are associated with an enhanced inflammatory response.

We hypothesized that ischemia/reperfusion (I/R) injury of the liver during normotensive gram-negative bacteremic sepsis alters the kinetics of circulating endotoxin, tumor necrosis factor-alpha (TNF-alpha), and coinduced mediators, thereby exacerbating sepsis-induced lung inflammation. Liver and lung dysfunction were studied after hematogenous infection of Sprague-Dawley rats with 10(9) Escherichia coli serotype O55:B5 (EC) and 90 min of secondary hepatic ischemia in EC + I/R and saline-infused (normal saline NS) x I/R rats, followed by brief (1 h) or longer reperfusion (24 h). TNF- alpha:leukotriene interactions in this model were examined using the 5-lipoxygenase-activating protein inhibitor MK-886. Compared with sham-operated EC + Sham animals, peak serum endotoxin, TNF-alpha, alanine aminotransferase, interleukin-6 (IL-6), and hepatic neutrophil (PMN) influx were higher in EC + I/R rats through 24 h (p < 0.05) despite comparable arterial pressure. Lung PMN influx and wet/dry weight ratios were likewise enhanced in EC + I/R versus EC + Sham or NS + I/R rats. MK-886 attenuated TNF-alpha concentrations and ischemic liver injury but not mortality. Thus, focal hepatic I/R augments circulating endotoxin, TNF-alpha, and postbacteremic lung inflammation early after normotensive E. coli bacteremic sepsis.

OBJECTIVE: To investigate the effect and mechanism of bactericidal/permeability-increasing protein (BPI) on sepsis induced by intra-abdominal infection in rats. METHODS: Cecal ligation and puncture (CLP) was made on 20 rats with sepsis induced by intra-abdominal infection. BPI or equal volume of physiological saline (PS) was intra-abdominally given immediately and 12 h after CLP, respectively (2.5 mg/kg of BPI each time). Plasma endotoxin levels were determined with limulus amebocyte chromogenic assay. RESULTS: (1) The survival time in BPI group was significantly higher than that in PS group. (2) The values of the mean arterial pressure (MAP), the left ventricular systolic pressure (LVSP), the isovolumic ventricular pressure (IP), and the maximal change of left intraventricular pressure (+/-dp/dtmax) in BPI group, although decreasing, were markedly higher than those in PS group. (3) Plasma glutamic-pyruvic transaminase (GPT) and urea nitrogen levels in BPI group, though increasing, were obviously lower than those in PS group. (4) There was no significant change of plasma endotoxin levels in BPI group, while plasma endotoxin levels markedly increased in PS group. CONCLUSIONS: BPI has obvious protective effect on sepsis induced by intra-abdominal infection, which might be related to its neutralization of endotoxin.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

Pharmacokinetics, clinical efficacy and safety of teicoplanin (TEIC) were evaluated in pediatric and neonate patients with MRSA sepsis in the dosages approved in overseas. The administrated dose for pediatrics patients was 10 mg/kg once at hour 0, 12 and 24, followed by every 24 hours intervals. In neonates patients, first dose was 16 mg/kg, then 8 mg/kg every 24 hours intervals. 1. Pharmacokinetic results. All 17 patients (9 neonates and 8 pediatrics) who received TEIC were evaluated for pharmacokinetics. Trough concentrations were analyzed in 16 patients (9 neonates and 7 pediatrics) excluding one patient for lack of measurement of drug concentration at day 7. No patient with a concentration exceeding 60 micrograms/mL in peak or trough concentrations were reported. Mean concentrations in trough at day 3, 4 and 7 in neonates were 15.2, 14.7 and 17.8 micrograms/mL, and in pediatrics were 12.5, 12.2 and 13.1 micrograms/mL, respectively. These results were similar to those reported in foreign pediatrics and neonates patients. 2. Efficacy and safety results. Since no patient was excluded, all patients were evaluated for efficacy and safety. Microbiological efficacy as well as clinical cure were secondarily evaluated in 2 patients for whom MRSA was isolated from blood. Clinical efficacy rate was 76.5% (13/17) and number of cases in judgments of excellent, good, fairly improved and no change were 12, 1, 3 and 1 cases respectively. The patients for whom MRSA was isolated from blood were judged as MRSA eradicated case and cured without any additional anti-MRSA drugs. Adverse events were reported in 2 neonates and 3 pediatric patients. Possibly related adverse events to study drug (adverse drug reactions) were: 1 case of respiratory disorder, thrombocythemia, gamma-GTP increased, GOT increased and GPT increased in 3 pediatrics. These results suggest that an application of overseas dose regimen of TEIC for neonate and pediatrics is appropriate in Japan.

Hepatic hemangioendothelioma (HE) is a tumor that presents in infancy and toddler. It manifests hepatomegaly, abdominal mass, jaundice, abdominal distention, or high output cardiac failure. We reviewed patients with HE in our hospital in the past 15 years (from July 1986 to June 2001). The diagnosis was made by the histology specimen or various imaging studies. There were thirteen patients (9 males, 4 females) enrolled in our study. Their ages ranged from neonate to 2 years old. The common clinical manifestations included abdominal distention (53%), congestive heart failure (38.5%), abdominal mass (30.8%), jaundice (30.8%), and skin hemangioma (23.1%). Nine patients had serum alanine aminotransferase examination and were abnormal in 2. Anemia was noted in 7 of 13 (53.8%) patients, thrombocytopenia and hyperconsumptive coagulopathy were found in 4 and 5 patients, respectively. Serum alpha-fetoprotein was elevated in 4 of 7 patients. Abdominal ultrasonography (n = 13) showed heterogeneous and hypoechoic lesions in the liver. Computed tomography (n = 11) revealed central hypointensity with peripheral enhancement after contrast of the liver masses. Magnetic resonance imaging studies of the hepatic masses (n = 3) showed decreased signal intensity on T1 images and high signal intensity on T2. Most patients were treated with steroid. Other management included interferon, chemotherapy, embolization and/or surgery. Four patients were managed conservatively. Among the other nine patients, four patients died of sepsis, hepatic failure, disseminated intravascular coagulopathy or tumor rupture with hemorrhagic shock. HE appears to be a histologically benign tumor but may have a poor outcome because of complications. For its management, steroid is a first-line medication. Other methods of treatment were interferon, hepatic artery embolization, chemotherapy and surgery. Long term follow up is needed for the evaluation of treatment response.

The liver is one of the major target organs affected in sepsis, and its failure always results in critical consequences. It has been reported that recombinant human interleukin 11 (rhIL-11), a pleiotropic cytokine, may be useful in the treatment of sepsis. However, the effect of IL-11 specifically on the hepatic failure in sepsis has not been evaluated. In the present study, we examined the effect of rhIL-11 on the hepatic injury in a rat endotoxemia model. Acute endotoxemia was induced in male Sprague-Dawley rats by intraperitoneal injection (i.p.) of bacterial lipopolysaccharide (LPS, 20 mg/kg). Immediately after injection of LPS, rats were treated with rhIL-11 (150 microg/kg, i.p.) or the vehicle. LPS treatment induced severe hepatic injury as revealed by marked increases in serum alanine transaminase (ALT) and aspartate transaminase (AST) activities, extensive hepatocyte necrosis, tumor necrosis factor-alpha (TNF-alpha) mRNA, inducible nitric oxide synthase (iNOS) mRNA, and DNA-binding activity of nuclear factor-kappaB (NF-kappaB). In contrast, rhIL-11 treatment significantly ameliorated the LPS-induced hepatic injury, as judged by marked improvement in all these indices. In addition, rhIL-11 treatment markedly decreased LPS-induced mortality. These results indicate that rhIL-11 plays a significant protective role in LPS-induced hepatic injury in acute endotoxemia.

Lipopolysaccharide is strongly associated with septic shock, leading to multiple organ failure. It can activate monocytes and macrophages to release proinflammatory mediators such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and nitric oxide (NO). The present experiments were designed to induce endotoxin shock by an intravenous injection of Klebsiella pneumoniae lipopolysaccharide (LPS, 10 mg/kg) in conscious rats. Arterial pressure and heart rate (HR) were continuously monitored for 48 h after LPS administration. N-Acetylcysteine was used to study its effects on organ damage. Biochemical substances were measured to reflect organ functions. Biochemical factors included blood urea nitrogen (BUN), creatinine (Cre), lactic dehydrogenase (LDH), creatine phosphokinase (CPK), aspartate transferase (GOT), alanine transferase (GPT), TNF-alpha, IL-1 beta, methyl guanidine (MG), and nitrites/nitrates. LPS caused significant increases in blood BUN, Cre, LDH, CPK, GOT, GPT, TNF-alpha, IL-1 beta, MG levels, and HR, as well as a decrease in mean arterial pressure and an elevation of nitrites/nitrates. N-Acetylcysteine suppressed the release of TNF-alpha, IL-1 beta, and MG, but enhanced NO production. These actions ameliorate LPS-induced organ damage in conscious rats. The beneficial effects may suggest a potential chemopreventive effect of this compound in sepsis prevention and treatment.
