Modern approaches to the therapy of septic shock.

Bacteremia from gram-negative rods is a great cause of concern for hospital physicians today. Shock-complicating gram-negative sepsis has a mortality rate of 60% and above, despite early diagnosis and treatment. Intensive research efforts have shown new pathophysiological mechanisms and mediators involved in septic shock, with changes in recommended treatment protocols. In this report, the authors review the use of corticosteroids, fibronectin, naloxone hydrochloride, and immunotherapy, with emphasis on theoretical considerations and relevant clinical experience. Although these treatment methods may have been promising initially, data from large double-blind human trials are either lacking or unencouraging. While continued research and modern therapeutic approaches should improve future survival rates from septic shock, use of the therapies reviewed should be considered experimental at this time.

Corticosteroids in sepsis and septic shock: has the jury reached a verdict?

Mortality from septic shock remains high, despite early diagnosis, comprehensive care and monitoring, and intensive therapy. The use of high-dose corticosteroids as adjunctive therapy in septic states has been extensively debated in the literature, but no clear consensus has been reached. Main sites of action where corticosteroids can theoretically interfere with the pathophysiologic processes activated by sepsis have been identified. Early clinical studies and extensive animal research generated much enthusiasm for the use of steroids in sepsis and septic shock. Recently, however, well-designed clinical studies have consistently failed to show a beneficial effect of corticosteroid use in septic states. After re-examining the theoretical basis for the use of steroids, possible side effects, experimental results and clinical trials, it is concluded that, based upon current knowledge, high-dose corticosteroids should not be used as adjunctive therapy in human sepsis and septic shock.

Enzyme immunoassay system for panel testing.

An immunoassay system based on enzyme immunoassay technology has been developed for quantitative panel testing. The system includes test card disposables, reagents, and an instrument. Patients' samples are processed semiautomatically in the instrument with minimum user intervention. The test card has multiple test areas at individual locations on a membrane solid phase so that simultaneous determinations from a single specimen are possible. Each panel also includes positive and negative reagent procedural controls. Factory-determined calibration curves for each analyte are provided in barcode form with each test kit. The reagents include a specimen dilution buffer, enzyme conjugate, and precipitogenic substrate. Up to 10 test cards at a time can be processed in random-access and continuous-access modes, with automated agitation of sample and reagents over the solid phase, temperature-controlled incubation, and membrane washing and reading, data reduction, and printout of results. The optical reader measures diffuse reflectance and features source intensity and wavelength compensation.

Adult respiratory distress syndrome: current concepts.

Adult Respiratory Distress Syndrome (ARDS) is a common diagnosis in today's intensive care units, representing a final common pathway of lung response to a variety of disease states. Mortality rates remain excessively high, despite comprehensive monitoring and intensive treatment. The incidence, etiology, clinical features, pathology and pathophysiology of ARDS are reviewed, with special emphasis on current research regarding potentially injurious mediators and possible etiopathogenetic mechanisms. Current therapy is summarized, and new therapeutic modalities are assessed. It is hoped that increased knowledge and awareness of the various aspects of ARDS will lead to further understanding and better clinical results in patients with this syndrome.

Waterborne typhoid fever in Haifa, Israel: clinical, microbiologic, and therapeutic aspects of a major outbreak.

A major outbreak of waterborne typhoid fever involving 77 verified cases occurred in 1985 in a large suburban area of Haifa, Israel. The authors summarize the clinical, microbiologic, and therapeutic aspects of these patients. Fever, usually higher than 39 degrees C, was the hallmark of the disease. Other manifestations of typhoid, although relatively frequent, are presented as part of a mild nonspecific symptom complex, often found only in the prodromal period. An elevated level of serum glutamic-oxaloacetic transaminase (mean, 81 IU/ml) was the most characteristic laboratory abnormality, occurring in 94% of the patients. Blood cultures were positive in 46 of the 50 patients (92%), and were not affected by prior outpatient antibiotic therapy. The first blood culture was diagnostic in 93% of the cases. Although fever tended to disappear more rapidly among patients receiving ampicillin than among those treated with chloramphenicol, results of therapy were similar in both groups. Nevertheless, the relapse rate of 36% among 25 chloramphenicol-treated patients was significantly higher than the 9% noted among 22 patients treated with ampicillin. Except for one case of hemolytic anemia, serious complications were conspicuously absent, and outcomes were uniformly favorable.

Benign recurrent intrahepatic cholestasis--25 years of follow-up.

Only 70 cases of recurrent intrahepatic cholestasis have been reported in the literature since the original description of this entity in 1959. The benign nature of the disease has been questioned, some authors suggesting progression to biliary cirrhosis. We report our follow-up of one such patient for over 25 years with no adverse physical consequences or histological deterioration. Sequential liver biopsies were obtained during this period. A conservative approach to diagnosis and treatment is therefore indicated.

Early use of naloxone in shock--a clinical trial.

Naloxone hydrochloride (N) 0.4-1.2 mg i.v. was administered during 10 episodes of shock (8 septic and 2 cardiogenic) in 9 adult patients. Shock was defined as systolic blood pressure (SBP) less than or equal to 90 mmHg and urine output less than 0.5 ml/h and signs and symptoms of hypoperfusion lasting for greater than or equal to 30 min, despite fluid loading to a CVP 5 cmH2O above baseline. N was given as early as 30 min after onset of shock and resulted in an increase of SBP from a mean of 75 +/- 10 to a mean of 130 +/- 25 mmHg maximum (P less than 0.01). Within 10-60 min urine output increased from 16 +/- 12 to 122 +/- 56 ml/h, heart rate, CVP and arterial blood gas tensions remained unchanged. No side effects were observed. Naloxone, even in small doses, may improve hemodynamic parameters in human shock, provided it is administered very early.
