The authors have compared 11 laboratory tests for diagnosis f neonatal sepsis: WBC cont, neutr. count, band count (> 8%), immature/mature neutrophil ratio (I:M > 0.2), throm. count, C reactive protein, alpha 1-antitrypsin, alpha 2-macroglobulin, IgM, GIC, C3 fraction of the complement. We determine higher sensitivity and specificity of CRP (80.1%; 80%), C3 fraction of the complement (82.4%; 86.5%) and I:M ratio (96.9%). We conclude that this tests are useful indicators of early diagnostic of neonatal infection.

In a prospective study of 65 patients with S. aureus septicemia, the clinical value of measuring serum IL-6 and lactoferrin levels was assessed and compared with CRP levels and WBC count. 20/65 (31%) patients had a CRP value < or = 100 mg/l on admission and 10 (50%) and 11 (55%) of these had serum levels of IL-6 > 100 pg/ml or lactoferrin > 2.0 mg/l, respectively. 41/64 (64%) patients had a WBC count < or = 15.0 x 10(9)/l and the corresponding figures for increased IL-6 and lactoferrin values were 29 (71%) and 21 (51%) patients, respectively. The high concentrations of IL-6 and lactoferrin on admission decreased rapidly during the hospital stay, better reflecting the clinical course than CRP and WBC count. Patients with endocarditis showed higher IL-6 levels and body temperatures both on admission and during the first days of hospitalization compared with patients without endocarditis.

Plasma fibronectic (pFN) is a high molecular weight multifunction glycoprotein, which augments neutrophil and macrofage phagocytosis and acts as a nonspecific opsonin for the reticuloendothelial system. In this study we have determined pFN concentrations in fifty eight preterm infants to discriminate infected from non infected ones. Concentrations of pFN decreased from baselin in babies with early or late onset infections. The changes in pFN concentrations were not found before sepsis, but on day 1. By day 5 pFN concentrations have increased and have been no longer different from controls. We have calculated sensitivity (73.68%), specificity (74.36%), positive (58.35%) and negative (85.29%) predictive values of pFN and of other markers of infections (C-reactive protein--CRP-, Immature/Mature neutrophil ratio--I/M n. ratio-). Adding these tests to pFN, provided equal specificity and positive predictive value, but increased sensitivity (94.73%) and negative predictive value (96.43%). Thus, low concentrations of pFN may be a valuable but not early marker for neonatal infections. The combination of pFN, CRP and I/M n. ratio increase the precision of diagnostic testing.

A case of psoas abscess associated with diabetes mellitus in the elderly is reported. A 81-year-old male who had been followed for cerebral thrombosis, diabetes mellitus and basal cell carcinoma was admitted to our hospital because of high fever. Leukocytosis, a positive CRP test and pyuria were seen. Proteus mirabilis and Escherichia coli were detected by urine and blood culture, respectively. He was treated with antibiotic therapy for urinary tract infection and sepsis. After starting treatment, a low grade fever continued. On the twenty first hospital day he developed pyrexia again, and a large abscess was demonstrated in the right psoas muscle by pelvic couputed tomography. The abscess was drained and a specimen from it yielded E. coli on culture. Treatment with antibiotics and drainage resulted in symptomatic improvement. In Japan, 82 cases of psoas abscess have been reported from 1990 to 1994. Four cases of these reports were above eighty years old. The experience with this case indicates the necessity of adequate care in cases of elderly diabetes complicated by psoas abscess.

From October, 1982, to December, 1995, 22 patients with active infective endocarditis underwent surgical treatment. Of 22 patients, 12 patients (group P) demonstrated microorganisms on blood culture obtained at the operation and/or in the excised valve, and 10 patients (group N) showed acute inflammatory reaction in the excised valve microscopically. Operative mortality in group P was significantly higher than that in group N (50% versus 0%,p < 0.01). Especially in group P, five of six patients (83%) with uncontorolled infection for more than eight days died within 30 days of operation. This showed that prolonged preoperative periods of uncontrolled infection influenced the surgical outcome of active infective endocarditis. In conclusion, patients who do not promptly response to antibiotic treatment must be considered for early operation within seven days of the diagnosis of infective endocarditis to decrease operative mortality. The plasma level of CRP and definition of sepsis may be useful as indicators of uncontrolled infection.

Psoas abscess is relatively rare and often difficult to make early diagnosis. We treated a patient suffering from hepatocellular carcinoma due to hepatitis C virus infection who was admitted to our hospital complaining of right inguinodynia and a high fever. Positive CRP test were seen. Staphylococcus aureus was detected from blood culture and he was treated for sepsis with antibiotic therapy. After starting treatment, his inguinodynia continued and abscesses were demonstrated in the right psoas muscle by pelvic computed tomography (CT). The abscesses were drained and a specimen yielded S. aureus on culture. After drainage, the symptoms improved and the abscesses disappeared on pelvic CT. Pelvic CT can be successfully used to diagnose psoas abscess and to monitor the efficiency of the treatment.

The accumulation of sCD14 shed from human monocytes in vivo might correlate with other inflammatory parameters and could be of importance in overcoming a sepsis situation. The development of the sCD14 titer in the supernatant of monocyte-enriched MNC cultures isolated from healthy volunteers was studied utilizing a commercially available sCD14 ELISA. These culture experiments revealed the prolonged liberation of sCD14 into the supernatant during a period of several days. A medium-exchange schedule of 2-3 days was found to be superior to a longer incubation period with respect to the sCD14 yield. PMA initially enhanced the CD14 shedding slightly, but after a few hours it strongly repressed the process. Such a reduction was also achieved by protein synthesis inhibitors (cycloheximide, actinomycin D). Additionally, we monitored the concentration of sCD14, CRP, IL-6 and IL-8 in human sera from healthy persons or patients suffering from severe burn injuries with or without sepsis. Our results indicate that sCD14 is strongly correlated with IL-6, but not with IL-8. sCD14 titers were higher in the group of patients with both burn injuries and sepsis. From experiments with monocyte-enriched MNC cultures isolated from healthy volunteers and medium supplemented with sera containing sCD14 as well as radiolabeled LPS, we conclude that the enhanced shedding of CD14 in vivo during sepsis is probably not able to reduce the binding of LPS to monocytes.

The body of literature concerning studies of the applications of CRP measurement in the pediatric population continues to grow. Based on current data serial CRP measurements appear to be most useful for monitoring patient response to therapy after the primary diagnosis of invasive infectious or inflammatory diseases, for monitoring patients after major surgical procedures and those with serious burns. Monitoring CRP over time may be used to assess for recrudescent disease, a secondary process or ineffective therapy. In addition CRP appears to be suited to most applications for which the ESR is used but offers many advantages. At present there are no objective outcome-based clinical trial data to justify using CRP values alone, whether elevated or normal, as a basis for management decisions regarding instituting or withholding antimicrobial therapy, or its early discontinuance for patients suspected of having neonatal sepsis, meningitis, bacteremia or pneumonia, regardless of immune status. In addition, because of significant inconsistencies among studies for which CRP has been applied to differential diagnosis of bacterial vs. viral diseases, including meningitis, acute otitis media and lower respiratory tract infection, we cannot recommend it for this purpose. Data do not support a role for CRP in differential diagnosis of acute appendicitis or for localizing urinary tract infections.

Patients with sepsis or after major surgery have decreased plasma levels of the anticoagulant protein antithrombin. In such patients elevated levels of interleukin-6 (IL-6) are present and this interleukin is known to induce positive and negative acute phase responses. To investigate the possibility that antithrombin acts as a negative acute phase response-protein we performed studies on the human hepatoma cell line HepG2 in vitro and baboons in vivo. HepG2 cells were treated with recombinant human IL-6, IL-1beta, or combinations of the latter two, and tested for production of antithrombin, fibrinogen and prealbumin (transthyretin). This treatment resulted in a dose dependent increase in fibrinogen concentration (with a maximum effect of 2.8-2.9-fold) and a dose dependent decrease in prealbumin (with a maximum effect of 0.6-0.7-fold) and antithrombin concentrations (with a maximum effect of 0.6-0.8-fold). Simultaneous treatment of the HepG2 cells with IL-6 (1,000 pg/ml or 2,500 pg/ml) and IL-1beta (25 pg/ml), provided more extensively decreased prealbumin (0.8 and 0.6-fold, respectively) and antithrombin concentration (0.7 and 0.6-fold, respectively) compared to the single interleukin treatment at these concentrations. Baboons treated with 2 microg IL-6 x kg body-weight(-1) x day(-1) showed increased plasma CRP levels (59-fold, p <0.05) and decreased prealbumin (0.9-fold, p <0.05) and antithrombin (0.8-fold, p <0.05) plasma levels, without evidence for coagulation activation. Our results indicate that antithrombin acts as a negative acute phase protein, which may contribute to the decreased antithrombin plasma levels observed after major surgery or in sepsis.

This report describes a 12-year-old girl who developed vaccine-type pneumococcal septicemia (type 4, Danish nomenclature) 2 years after splenectomy for recurrent idiopathic thrombocytopenia despite vaccination with the 23-valent vaccine 4 weeks before surgery and antibiotic prophylaxis with penicillin V. The disease presented as high fever with shivering and vomiting followed by disseminated petechiae and a deteriorated general condition. Initial laboratory studies showed severe sepsis with leucocytopenia and thrombocytopenia, a markedly elevated CRP, and disseminated intravascular coagulation. Despite antibiotic treatment, which was initiated with clindamycin, cefotaxime and trimethoprim/sulfamethoxazole and was switched to cefotaxime and penicillin after the result of the blood culture had been obtained, the patient had to be ventilated, and hemofiltration became necessary because of acute renal insufficiency. Furthermore, she required amputation of all her toes because of severe necrosis. No type-specific pneumococcal antibody titers were detected during and after infection. It remains unclear whether the susceptibility to Streptococcus pneumoniae was due to primary failure of antibody production or a decline in antibody levels after vaccination. Patients and/or their relatives should be informed that neither vaccination nor continuous antibiotic prophylaxis can guarantee full protection against infection with S. pneumoniae in patients after splenectomy.
