In a prospective study 19 adult patients with nephropathia epidemica were examined in the acute phase of disease with computed tomography (CT) of the lungs and conventional chest radiography. Infiltrates and/or pleural effusions were seen in ten of 19 patients. In two of the patients, abnormalities were disclosed only by CT. Patients with pathologic radiography findings had a more pronounced inflammatory response, as measured by C-reactive protein and leukocyte count, than did those with normal radiography findings. It is concluded that radiological evidence of pulmonary involvement is a common finding early in the course of nephropathia epidemica. The possibility that the lung may be a site of viral replication merits further investigation.

Infection causes disturbances in lipid metabolism that may be mediated by cytokines. Therefore we studied plasma lipids, lipoproteins, triglyceride (TG) metabolism, and serum cytokines in three groups: patients with the acquired immunodeficiency syndrome (AIDS) without active secondary infection, patients with evidence of human immunodeficiency virus infection but without clinical AIDS (HIV+), and controls. Plasma TGs and FFA were increased in AIDS, while plasma cholesterol, high density lipoprotein (HDL) cholesterol, apolipoprotein-A-1 (Apo-A-1), low density lipoprotein (LDL) cholesterol, and Apo-B-100 levels were decreased. Increased TG levels in AIDS were primarily due to increases in very low density lipoprotein of normal composition; in addition, LDL and HDL were TG enriched. In HIV+, TGs and FFA were not increased, but total cholesterol, HDL cholesterol, Apo-A-1, and Apo-B-100 were significantly decreased. Interferon-alpha (IFN alpha) and C-reactive protein levels were increased in AIDS, but tumor necrosis factor and haptoglobin levels were not. There was a significant correlation between plasma TGs and IFN alpha levels (r = 0.477; P less than 0.01), but not between TGs and tumor necrosis factor, C-reactive protein, haptoglobin, or P-24 antigen. In addition, there was no relationship between circulating IFN alpha levels and plasma cholesterol, HDL cholesterol, Apo-A-1, LDL cholesterol, Apo-B-100, or FFA. TG clearance time and postheparin lipase were significantly decreased in AIDS and HIV+. There was a strong correlation between serum IFN alpha levels and TG clearance time in AIDS and HIV+ (r = 0.783; P less than 0.001). In summary, decreases in cholesterol and cholesterol containing lipoproteins (including HDL) in both AIDS and HIV+ precede the appearance of hypertriglyceridemia and are not related to IFN alpha or TG levels. Our data raise the possibility that with development of AIDS, subsequent increases in IFN alpha may contribute to increases in plasma TG levels in part by decreasing the clearance of TG.

The efficacy of imipenem-cilastatin was compared with that of tobramycin and metronidazole for the treatment of appendicitis-associated abdominal infections in children in an open, randomized trial. Two hundred eighteen patients between 2.5 and 16.8 years of age hospitalized for appendectomy because of suspected acute appendicitis were allocated to 5 treatment groups. The appendix was perforated in 54 (33.8%) of the 160 cases with appendicitis. All patients responded favorably to treatment. Infection in the wound occurred in 15 of 125 (12.0%) of those without preoperative antibiotic therapy and in 5 of 83 (6.0%) of those given imipenem preoperatively (P = 0.12; 95% confidence interval, -2.2 to 14.2%). C-reactive protein decreased significantly faster in those with perforated appendix treated with imipenem than in those treated with tobramycin and metronidazole (58.2 mg/liter vs. 89.4 mg/liter, P less than 0.05 on the third postoperative day). Imipenem-cilastatin was at least as effective and economically comparable as tobramycin and metronidazole for the treatment of appendicitis-associated infections in children.

A review of 27 cases of bacterial endophthalmitis diagnosed and treated at the Specialized Outpatient Department for Infectious Eye Diseases at the 2nd Department of Ophthalmology of the University of Vienna over a period of eight years (January 1983-April 1991) is presented. In 70% of the cases the patients had undergone surgical intervention. Conjunctival samples were routinely taken for microbiological investigations (aerobic as well as anaerobic cultures). In 19 patients (70.4%) aqueous specimens were obtained, in 22 cases (81.5%) vitreous specimens collected during vitrectomy for the removal of infected material were used for microbiological diagnosis. The results for the patient population described showed the poor reliability of conjunctival cultures from intraocular infections with only 36.84% being identical with those of the vitreous specimens. In the most recent 11 patients three serological parameters of inflammation were tested on various occasions: C-reactive protein, PMN- elastase and light immunoglobulin chain assembling (kappa/lambda). Clinical results, microbiological findings and therapeutic approaches are presented and discussed.

As only insufficient knowledge about the dosage of teicoplanin in hemodialysis patients exists, a clinical trial was performed on 26 patients. An initial dose of 800 mg teicoplanin, followed by doses of 400 mg on day 8 and day 15, was administered. In addition to the common clinical parameters (fever, white blood cell count, C-reactive protein), the plasma concentrations of this substance were determined. The HLTterm was 159 +/- 35 h, the Vss 104 +/- 25 1/100 kg and the CLtot 5.3 +/- 1.3 ml/min. It could be shown that the dosage regimen mentioned above produced long-lasting and highly effective levels, sufficiently surpassing the MICs of the expected bacteria (streptococci and staphylococci). The easily administered substance showed no adverse side effects, based on clinical criteria. The above-mentioned therapy nearly always resulted in success according to clinical criteria. Therefore, and due to its easy administration, it seems advantageous to start treatment with teicoplanin in hemodialysis patients obviously suffering from bacterial infections.

The value of C-reactive protein (CRP) determinations in the analysis of fever after allogeneic bone marrow transplantation (BMT) was studied prospectively by serial measurements of serum CRP levels during 30 BMT episodes in 28 children and adolescents. The treatments and procedures accompanying BMT did not elicit a significant CRP response. Forty-three febrile episodes were registered and analyzed, without previous knowledge of the results of CRP determinations. The incidence of bacterial infection and acute graft-versus-host disease (GvHD) was low, 8/30 and 5/30, respectively. Raised CRP levels occurred only once in association with GvHD. A CRP level higher than 50 mg/l was not sensitive as an indicator of bacterial infection (4/8). A CRP level below 50 mg/l in the presence of fever, however, excluded bacterial infection with a specificity of 86% and a negative predictive value of 88%. When timed properly and interpreted together with clinical and microbiological findings, CRP measurements can be a valuable aid in the management of fever after BMT, especially as a negative predictor.

Over a three year period (January 1985 through December 1987), 221 children with prolonged pyrexia were admitted to the paediatric departments in two regional hospitals in Kuwait. Infections, connective tissue diseases and malignancies constituted 78%, 5% and 2%, respectively, and 15% of the cases remained undiagnosed. Brucella was the most common infectious agent encountered (38% of all cases), followed by typhoid fever (9%). The duration of fever was more helpful in the differential diagnosis than its height or pattern. The erythrocyte sedimentation rate and the white blood count were of limited value, and the C-reactive protein was positive in bacterial infections, malignancies and connective tissue diseases. Since a child presenting with prolonged pyrexia in this country has over a 70% chance of having a bacterial infection, both diagnostic and therapeutic procedures should be performed as an emergency measure. Particular emphasis should be put on the exclusion of brucellosis.

Infections due to Streptococcus pyogenes are varied and often difficult to diagnose. During the last few years the clinical manifestations of these infections and the treatment rationale have changed. New diagnostic tests have been introduced. The present article reviews the diagnostic possibilities based upon clinical findings, the doctor's own laboratory and the microbiological laboratory. Rapid immunological tests, differential leukocyte count and C-reactive protein are pointed out as potentially useful laboratory tools for the clinician.

The diagnostic validity of multivariate combinations of alpha 1-antitrypsin, alpha 2-macroglobulin, C-reactive protein, complement C3, complement C4, neopterin in serum, and neopterin in urine as markers for acute cardiac allograft rejection and for differential diagnosis of rejection and infections was investigated in the follow-up of 37 patients with heart transplants. Rejection was diagnosed by endomyocardial biopsy. Infections were classified as 'no infection', 'viral infection', and 'bacterial, fungal or mixed infections'. Although there are significant differences between the mean levels of analytes, multivariate discriminant analysis does not provide an adequate discrimination of rejection and infection states. In separate rejection diagnosis, multivariate combinations of analytes cannot replace endomyocardial biopsy. However, a multivariate combination of alpha 1-antitrypsin, alpha 2-macroglobulin, C-reactive protein, C3, C4 in serum, and neopterin in urine can be used as a screening procedure to reduce the number of endomyocardial biopsies.

Serum C-reactive protein (CRP) concentration was studied in patients with newly diagnosed post-primary pulmonary tuberculosis and in those with malignant intrathoracic tumors. In tuberculosis, there was a wide scatter in CRP values and the mean did not differ from that of the tumor patients. Tuberculous patients with cavitation in chest X-ray had significantly higher levels of CRP than those without as well as healthy controls. Normal CRP did not exclude tuberculosis and all the values were below 100 mg/l.
