Three hundred ninety-seven insulin-dependent diabetic dialysis patients were screened by nursing staff for analgesic-seeking behavior. Thirty-eight patients were identified and classified as prescription abusers (n = 26) or illicit drug users (n = 12). The nine cocaine users, when compared with 14 insulin-dependent diabetics on dialysis matched by protocol, were found to be similar in terms of diabetic retinopathy and metabolic neuropathy. Although statistically not significant, cerebrovascular and cardiovascular complications were more common in the study group. Gastroenteropathy with malnutrition was more common the study group (P less than 0.025). Infection rate and severity were markedly worse in the cocaine group: bacterial cellulitis, sepsis, and abscess each increased greater than fourfold. All the visceral infections were in the cocaine-using group. Hepatitis viral antigen and antibody was increased 10-fold in the cocaine users. Recommendations for management of dialysis patients with analgesic-seeking behavior are formulated in light of these findings.

Antibiotic usage for initial empirical treatment of infections in hospitalized patients was assessed by means of a questionnaire sent to physicians in charge of surgical and medical intensive care units, departments of neurosurgery, neurology, general surgery, thoracic surgery, internal medicine and pediatrics. Analysis of a total of 82 questionnaires filled in by the various departments revealed that the most frequently used regimens for initial empirical therapy were combinations of a broad spectrum penicillin with an amino-glycoside or of a second generation cephalosporin with an aminoglycoside in intensive care. Third generation cephalosporins ranked third among combination partners with aminoglycosides. Imipenem and fluoroquinolones were used only rarely for first line treatment. Second line treatment was most frequently with third generation cephalosporins or imipenem/cilastatin for internal wards and intensive care with an extension for staphylococcal infections with vancomycin or teicoplanin as the most frequent additional antibiotics. Patterns of antibiotic usage changed with regard to infection sites with a predominance of third generation cephalosporins or broad spectrum penicillins in combination with an aminoglycoside and metronidazole in abdominal sepsis and peritonitis. In case of pneumonia a differentiation between community acquired and hospital acquired pneumonias was made. Treatment was predominantly carried out with penicillin G, ampicillin or a second generation cephalosporin with or without the addition of an aminoglycoside in case of community acquired pneumonia. The addition of clindamycin or metronidazole was considered for suspected staphylococcal infection or aspiration pneumonia. Third generation cephalosporins were preferred for pneumonia treatment in surgical patients.

Incidence and fatality of neonatal sepsis in intensive care units have been relatively high despite progress in the management of very ill neonates and combined treatment of sepsis with antibiotics. Between 1985 and 1989 944 children (632 premature babies and 312 term babies) were treated in the intensive care unit of the University Children's Hospital of Kiel. The incidence of sepsis was 5% (congenital sepsis 4%, sepsis acquired after birth 1%). Pneumonia occurred in 4% (congenital pneumonia in 2%, postnatal pneumonia in 2%). Early diagnosis and treatment with piperacillin plus cefotaxime reduced the mortality rate of sepsis to 2%. Sepsis never developed under treatment with piperacillin plus cefotaxime. Early recognition of neonatal sepsis by a good blood culture technique and beginning of treatment on first suspicion of sepsis with cefotaxime and piperacillin can improve the results especially in intensive care patients.

This study examined lipopolysaccharide (LPS) induced in vitro secretion of interleukin-1 (IL-1) by peripheral blood monocytes from pre-term infants with and without sepsis. Thirteen pre-term babies were tested; eight were completely healthy and five suffered from six episodes of sepsis. The latter group was tested both in the acute septic phase and in the convalescent period. IL-1 secretion by monocytes derived from septic pre-term infants was lower, but not significantly different from healthy pre-term infants (7.1 +/- 1.0 U/ml versus 8.1 +/- 0.9 U/ml, respectively). IL-1 secretion by monocytes of eight control full-term babies was in the same range (8.4 +/- 0.6 U/ml). In the convalescent period IL-1 secretion by monocytes from septic pre-term babies increased (9.0 +/- 0.3 U/ml) and was significantly higher than values measured during acute infection (p less than 0.05). Septic premature babies were also found to have higher absolute blood neutrophil concentration (p less than 0.001), but their body temperature did not increase along the infectious stage. The decreased secretion of IL-1 by monocytes from pre-term babies in the acute phase of infection compared to the convalescent period may have contributed to their inability to mount appropriate immunological as well as inflammatory responses. Sepsis promoting IL-1 production in vivo may have limited the monocytes' capacity for LPS stimulated IL-1 synthesis in vitro.

In a multicenter observational study of 163 medical and surgical patients with a total of 173 episodes of sepsis or septic shock (Elebute sepsis score: 19.0 +/- 0.5), the effects of supplemental i.v. immunoglobulin (i.v. IG) treatment (unmodified polyvalent IgG pH 4.25, n = 123; for Pseudomonas sepsis, n = 50, Pseudomonas IgG) on multiple organ failure (MOF) were investigated by means of APACHE II score changes (pretreatment: 23.7 +/- 0.6). In 44% of the cases ("responders"), a prompt improvement in APACHE II score (defined as decrease greater than or equal to 4) was evident from day 0 to day 4 after onset of therapy, thus being in close time relationship to the i.v. IG administration. This improvement, associated with a better prognosis (mortality 24% vs. 55%), was found in all subgroups, most importantly the following: polyvalent IgG vs. Pseudomonas IgG treatment; medical vs. surgical patients; moderate vs. severe MOF; and gram-positive vs. gram-negative septicemia. In a small-sized second comparative nonrandomized control group (n = 27, antibiotic treatment alone) of septic patients (Elebute: 14.7 +/- 1.0) with similar MOF severity (APACHE II: 23.6 +/- 1.4), the response rate (30%) was, though not statistically significant, lower by one-third. The optimal baseline score ranges for patient inclusion into future placebo-controlled randomized i.v. IG trials were found to be 20-35 for the APACHE II score and 12-27 for the Elebute score.

Twenty-five pediatric orthotopic liver transplantations (OLTs) performed in 22 patients at Sainte-Justine Hospital were reviewed for infections complications. One patient died within 12 hours posttransplantation and is excluded. The patients had an average age of 6.1 years (range, 1.25 to 19 years) and an average weight of 20.4 kg (range, 11 to 55 kg). Two patients (9%) were cytomegalovirus (CMV) seropositive and 9 of 19 patients (48%) were Epstein-Barr virus (EBV) seropositive preoperatively. Five of the donors (20%) were CMV seropositive. The most common indications for OLT were biliary atresia (8) and tyrosinemia (7). There were 4 deaths, for an overall mortality rate of 19%. In 3 patients, deaths were related to infection (CMV hepatitis and duodenitis with aortoduodenal fistula, adult respiratory distress syndrome [ARDS] with Streptococcus viridans pneumonia, Escherichia coli cholangitis with progressive hepatic failure). Fifteen patients (72%) had 41 major infections, most of them bacterial, during the first month posttransplantation. These include pneumonia (25%), line sepsis (17%), cholangitis (14%), and tracheitis (14%). There was only one major viral infection, a CMV hepatitis that occurred in the first month posttransplantation. Three patients had fungal infections (8%) associated with hepatic artery thrombosis and recurrent cholangitis. All three patients required retransplantation. There was only one protozoal infection (Pneumocystis carinii pneumonia) causing life-threatening respiratory failure, from which patient recovered without sequelae. Infection still remains a serious complication of OLT. Bacterial infection is common and is usually associated with technical complications. The low rate of CMV infection is related to low incidence of CMV in the donor pool and the minimal use of strong immunosuppressants.

Infection and sepsis are generally considered as causally related to death in intensive care unit (ICU) patients, but in several studies a decrease in infection rates was not associated with lower mortality. We therefore investigated the causes of death in surgical ICU patients, with special regard to the relationship between infection and mortality. MATERIAL AND METHODS. During the investigation period of 6 months, 502 patients were treated in the ICU (cardiac surgery: 222, thoracoabdominal surgery: 125, vascular surgery: 84, others: 14). In all patients each antibiotic therapy and infection was documented, as was the sepsis score. Definitions of infection and bacteriological monitoring were described in detail previously. In all deaths, attention was paid to an infection that was causally related to or contributed to death. In unclear cases a postmortem examination was performed. RESULTS. Forty-two patients died (8.4%). During the first 4 days 23 patients died, 11 within 24 h, because of severe trauma with severe underlying disease (main reason for death: cardiac 30%, cerebral 32%). Infections were not significant in these patients. Nineteen patients suffered from 1 or more infections (total 30). They died after a median of 16 days. The leading cause of death was multiple organ failure. In 7 of these patients a life-threatening infection was the reason for admission and, later, death. In 8 patients a nosocomial infection was causally related to or contributed to death. In the 4 other patients a postmortem examination excluded an infection as being responsible for death. DISCUSSION. More than one-half of the deaths were caused by severe trauma or severe underlying disease. Nosocomial infections could only be related to death in 1.6% of the 502 treated ICU patients. The influence of new therapeutic regimens on infection and mortality can therefore only be investigated in multicenter trials.

Despite the advances in medical technologies, ARDS is highly lethal. In the management of patients with ARDS, certain clinical conditions are common predisposing factors to the development of the syndrome. Infection, sepsis syndrome, and conditions requiring massive transfusion are the most common causes in patients initially managed by obstetricians and gynecologist. Early recognition of ARDS with timely consultation is of paramount importance in these patients. Early in the course of the illness, the patient should be placed in an intensive care unit. Physicians with experience in the altered pulmonary physiology should be included in the team, as well as infectious disease and renal consultants, as the situation demands. Due to the overall relative youth of our obstetric and gynecologic patients and their lack of other underlying diseases, they should do better than most patients with ARDS. However, at least 50% of all patients succumb to the disease itself or to complications inherent in the care needed. Families and treating physicians should be apprised of this early in the course.

This prospective study was designed to determine the value of a daily modified biophysical profile in detecting infection in patients with preterm premature rupture of the membranes who were managed expectantly. Ninety-nine patients received daily nonstress tests and biophysical profile scores. Results of the last predelivery study were related to subsequent development of amnionitis or fetal sepsis. Infection was present in 16 patients. When the biophysical profile score was 0/8, infection was uniformly present. When fetal breathing was absent (biophysical profile score, less than or equal to 4/8) and nonstress test was nonreactive, infection was present in 75% of cases (sensitivity, 75%; specificity, 95%). Because a nonreactive nonstress test could be secondary to prematurity instead of infection, these results were analyzed over time. Those who initially had a reactive nonstress test that subsequently became nonreactive were more likely to be infected. We conclude that a daily biophysical profile score and nonstress test can detect infection and propose delivery of patients with a biophysical profile score of 0/8 and nonreactive nonstress test. Patients with absent fetal breathing and a nonstress test that changes from reactive to nonreactive also should be considered for delivery. Absent fetal breathing with a reactive nonstress test or a consistently nonreactive nonstress test should have further testing to rule out infection.

Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these indications, liver biopsy will demonstrate a significant disease involving the liver in about 50% of patients with AIDS and in about 25% of patients who are HIV seropositive but who are not known to have AIDS. The clinical impact of a diagnostic biopsy is blunted by a lack of efficacious therapy for many opportunistic infections.
