Phase reactants were evaluated prospectively in babies suspected of having sepsis. Among 318 babies, there were 22 proven and 10 "very probable" cases of neonatal sepsis. Of the proven cases 14 survived and 8 died. The survivors had a positive latex C-reactive protein (CRP) in 11 cases and an alpha1-acid glycoprotein (AGP) level greater than 0.5 g/l in 12 cases. Among those who died, one had a positive latex CRP and none had AGP greater than 0.5 g/l. These findings were supported by positive CRP and elevated AGP in almost all "very probable" cases, all of whom survived. These data in newborn infants support the hypothesis that acute phase reactants have a functional role in combating infection.

C-reactive protein (CRP) and immature: total neutrophil ratio (I/T-ratio) were evaluated as tests to detect neonatal sepsis in a prospective study in 185 neonates. The positive predictive values (P.P.A.) of CRP and I/T-ratio when used for screening for infection were 20-30% in early onset and 50-60% in late onset infection. In patients with clinical signs of infection the P.P.A. of CRP and I/T-ratio was 35-45% in early onset and 65-70% in late onset infection. For the whole group of patients the negative predictive accuracy (N.P.A.) of both CRP and I/T-ratio was high, in early as well as in late onset infection (90-98%). Based on incidence rates of 7.5% and 23% for early and late onset infection respectively the chance that the infant was not infected was already 92.5% and 77% for the two types of infection. In conclusion, CRP and I/T-ratio determination are of limited value as diagnostic tests in neonatal infection.

Gastrointestinal manifestations in a lupus patient may be due to different aetiologies such as vasculitis or a surgical condition. Problems of diagnosis are frequently encountered because the clinical presentations may mimic each other. We analysed ten lupus patients with acute surgical abdomen to identify the clinical, laboratory and radiological features that may aid in early diagnosis and management. Three patients with surgical abdomen had concomitant active lupus. Intra-abdominal sepsis and bleeding peptic ulcer disease constituted two major causes of laparotomies. Overt signs of peritonitis might not be present due to steroid masking effect. There were no specific clinical features, laboratory or radiological tests that could distinguish gastrointestinal vasculitis from acute surgical abdomen. Blood cultures, C-reactive protein and CT abdomen were useful adjuncts in the management of abdominal sepsis. No correlation was found between the timing of surgery, mortality, steroid dosage and wound complication.

We analyzed the results of determinations C-reactive protein (Latex Test Dialab firm) of 136 newborns. We divided them into three groups: with generalized infections, with infection without sepsis and without infection. Sensitivity of method for neonates with septicaemia was 60%, for neonates with infection without sepsis--81.25%, together for all infections--66.1%. After overlooking sepsis caused by Staphylococcus epidermidis sensitivity for sepsis was 81.8% and for all infections--81.6%.

The relation of (multiple) organ failure (OF) to the release of inflammatory mediators and the incidence of infection and sepsis was studied prospectively in 100 patients with multiple trauma (injury severity score = 37). Sixteen patients died of OF, 47 patients survived OF, and 37 patients had no OF. Fifteen (24%) of the patients with OF showed no signs of infection. In patients with early onset of OF (n=45), infection followed with a lag of 2 or more days. In 16 (44%) of these patients, infection led to a deterioration in organ function. With late onset of OF (n=18), infection preceded OF in nine patients. Polymorphonuclear leukocyte-elastase, neopterin, C-reactive protein, lactate, antithrombin III, and phospholipase A discriminated significantly among the three outcome groups. Of all factors, only polymorphonuclear leukocyte-elastase showed a difference between patients with and without infection or sepsis, respectively. These data indicate that infection might not play a crucial role in the pathogenesis of posttraumatic OF in a substantial portion of patients with trauma. Early OF, especially, seems to be mainly influenced by the direct sequelae of tissue damage and shock (eg, the release of inflammatory mediators). Since infection and sepsis did not lead to an augmented release of mediators in patients with trauma, the role of both entities remains unclear.

In a prospective study elastase alpha 1-proteinase inhibitor (E alpha 1PI), polymorphonuclear (PMN) count, the immature to total neutrophil count ratio (I/T ratio), and C-reactive protein (CRP) were analysed in 74 patients (76 cases) with neonatal septicaemia at the time of initial clinical symptoms. At that early stage of the disease, 94% of the patients had abnormal values for E alpha 1PI, 71% for I/T ratio, 61% for PMN count, and only 54% for CRP. PMN count was a poor indicator of septicaemia. Neutropenia, present in 26% of all patients, was related to normal E alpha 1PI in only 4 patients. The combined use of E alpha 1 and I/T ratio was the most sensitive indicator. In all patients irrespective of causative bacteria or disease onset at least one of these parameters was elevated. In early-onset septicaemia (n = 31), normal CRP values occurred significantly more often (63%) than in late-onset sepsis (33%). Even in five of the seven fatal cases, initial CRP measurements were normal. The sensitivity of PMN count and I/T ratio did not differ significantly between early- and late-onset septicaemia. Laboratory changes observed in 18 newborns during the first 3 days of the septic episode show that the rate of pathological values for E alpha 1PI and I/T ratio was highest at the time of initial clinical symptoms and decreased on days 2 and 3. In contrast, CRP reached maximal values as late as day 2 (88% abnormal values), followed by a decrease on day 3. We conclude that the use of E alpha 1PI may improve the laboratory detection of neonatal septicaemia especially if used in combination with I/T ratio.

Cytokines are immunoregulatory molecules that are important mediators of the host response to stress and infection. Infants and children undergoing major surgery are particularly at risk of developing sepsis and have altered metabolic responses to surgical stress compared to adults. We have investigated the temporal sequence of cytokine responses in six infants (mean age, 11 +/- 7.5 months) undergoing pull-through operation for Hirschsprung's disease and correlated them with hemodynamic and biochemical parameters. Tumor necrosis factor (TNF-alpha), interleukin-1 beta (IL-1 beta), and interleukin-6 (IL-6) were measured by ELISA preoperatively, intraoperatively (hourly), and 24 and 48 hours postoperatively. IL-6 levels increased significantly in all cases within 2 hours of commencement of the operation (P less than .01) and were maximal 24 hours postoperatively. No significant changes in IL-1 beta levels (mean range, 70 to 110 pg/mL) were seen in these patients. TNF levels were undetectable (less than 20 pg/mL) throughout the study. Cortisol levels were increased in all patients during operation. Serum C-reactive protein levels were first detected 24 hours postoperatively and continued to increase 48 hours postoperatively. Hemodynamically, heart rate increased during the first 3 hours of operation and correlated with increase in IL-6 levels. Blood pressure and temperature changes did not correlate with cytokine levels. This study identifies IL-6 as the earliest detectable cytokine response associated with major surgery in infants. It also suggests that IL-6 can be unregulated, independently of other cytokines, in response to surgical stress.

We studied prospectively the value of administration C-reactive protein (CRP) in the diagnostic evaluation of the child with cancer hospitalized for fever and neutropenia. During a 7-month period 74 patients with malignant disease had 122 hospital admissions because of fever and neutropenia. All patients had a serum CRP obtained 8 to 24 hours after the onset of fever as part of their initial evaluation. There was a borderline correlation between serum CRP concentration and temperature at admission (P = 0.06). Patients with fever without an identifiable source had significantly lower CRP concentrations compared with those having focal or microbiologically documented infection (34.9 +/- 6 vs. 70.2 +/- 12 mg/liter; P = 0.0005). Twelve patients had positive blood cultures, 5 of which were coagulase-negative staphylococci considered to be central venous catheter-related infection or colonization. CRP concentrations were significantly lower in these 5 patients compared with the 7 patients with septicemia caused by other organisms (21 +/- 9 vs. 113 +/- 23 mg/liter; P = 0.01). In distinguishing between septicemic and nonsepticemic children, serum CRP was found to have excellent sensitivity and negative predictive value at concentration limits of 20, 50 and 100 mg/liter. However, both specificity and positive predictive value were low at these respective levels, thus limiting the overall utility of serum CRP in the initial empiric management of the febrile, neutropenic child with cancer.

Eighty-four patients with serious infection due to Entamoeba histolytica were evaluated for systemic complications by objective criteria for dysfunction of the organ systems normally assessed in surgical sepsis. Of 71 patients with amebic liver abscess (ALA), 41% had systemic complications and 13% had more than one organ system involved. Patients > or = 40 years of age and those being treated with steroids were at significantly increased risk of developing complications (P < or = .05). The erythrocyte sedimentation rate and the levels of the acute-phase markers C-reactive protein (CRP) and serum amyloid A (SAA) were significantly elevated in patients with ALA over values in those without ALA (P < or = .05). ALA patients with complications had lower CRP and SAA concentrations than those without complications (P < or = .05). Blood and liver aspirates in ALA patients were usually bacteriologically sterile. The pathogenesis of systemic complications and the associated acute-phase response requires further study, and ways of predicting disease severity and intervening therapeutically must be devised.

We evaluated serum C-reactive protein (CRP) level and serum sodium concentration as early indicators of bacteremia in neutropenic children in two different series in 1983-1984 (49 bacteremias) and 1989-1990 (29 bacteremias). During the earlier period, the goal was to avoid unnecessary antimicrobial therapy. Currently a neutropenic patient is placed on antimicrobial therapy at the first sign of fever. In 1983-1984 the serum CRP concentration was elevated in every case, whereas in 1989-1990 it was normal in 34% cases (P = .0001). Hyponatremia was detected on admission in 84% and 52% cases (P = .0001). The urinary sodium concentration was elevated in most cases. The mortality in bacteremia was 22% in 1983-1984 compared to 3% (P = .025) in 1989-1990. Prompt initiation of empirical antimicrobial therapy in children with fever and neutropenia invalidates the use of hyponatremia and an elevated CRP level as early indicators of sepsis.
