During 1980 and 1981, an epidemiological survey (biotyping, serotyping, beta-lactamase production) of Haemophilus strains isolated in our hospital was performed. One hundred sixty-one Haemophilus were isolated among 146 patients: 17 H. parainfluenzae and 144 H. influenzae. Most of the infections occurred in patients, under 3 years old (77%), during cold weather (63%), and in males (55%). Biotypes I, II and III were the most common isolates (88%). Capsulated strains were frequent (53%). A beta-lactamase occurred in 9, 5% of cases. Distribution of serotypes and biotypes will be discussed in relation to clinical findings (meningitis: 21, septicemia from other origins: 9, arthritis: 2, and other non-systemic infections).

The hyperimmunoglobulin E recurrent-infection syndrome (HIE) entails a disorder of recurrent bacterial infections of the skin and sinopulmonary tract commencing in infancy or early childhood in the presence of serum levels of IgE which are at least 10 times normal (greater than 2,000 IU/ml). Variable concomitants of HIE are coarse facies, chronic eczematoid rashes, cold cutaneous abscesses, mild eosinophilia, mucocutaneous candidiasis, and a neutrophil chemotactic defect. The bacteria which commonly infect these patients are Staphylococcus aureus and Haemophilus influenzae although Streptococcus pneumoniae and enteric gram-negative rods are seen in some cases. Other than pneumonias, deep-seated infections are unusual, although osteomyelitis, arthritis, and visceral abscesses are seen. Bacteremia and sepsis are rare. Therapy should involve prolonged intravenous antibiotics and early surgery to treat infections which usually seem deceptively benign. HIE patients' neutrophils display a variable chemotactic defect, and their mononuclear cells variably produce an inhibitor of neutrophil chemotaxis. The production of the inhibitor correlates with the in vitro chemotactic defect. The basis of the propensity for recurrent infections is still speculative, and the further study of this syndrome should add new dimensions to our understanding of host defenses against bacterial invaders.

Various parameters of fibrinolysis inhibition and the plasma concentration of fibronectin (alpha 2-surface binding glycoprotein, cold insoluble globulin) were measured in patients at risk of developing acute progressive respiratory sufficiency following trauma or sepsis - the delayed microembolism syndrome (DMS). Most parameters measuring fibrinolysis inhibition were significantly higher in the five patients with DMS than in five patients who did not develop the syndrome. Thus, the primary fibrinolysis inhibitor (alpha 2-antiplasmin) was enhanced and the alpha-form of this inhibitor, with affinity to plasminogen, showed the greatest increment and might be of major importance for the delayed elimination of fibrin from the lungs occurring in these patients. The fibronectin concentrations were not lower in patients with DMS than in those who did not develop the syndrome.

During the past twenty years 793 strains of Listeria monocytogenes were isolated from human beings in the Netherlands; of these 193 were taken from neonates and babies up to two months old. Isolations from adults came from patients (242) as well as clinically healthy people (358). Septicaemia appeared to occur to an equal extent in men and women (20 and 29 respectively), whereas meningitis was found more often in men than in women (50 and 22 respectively). A clear predisposition for L.m. develops after administration of immunosuppressive treatment and also in cases of liver disorders. Among veterinary surgeons listeriosis has been observed as an occupational disease. Isolations from animals have shown that L.m. may cause infections in every species of warm-blooded animal. Next to meningitis and abortus chronic and atypcial symptoms of the disease may be observed in animals. Epizootic spread of the disease has hardly ever been observed in the Netherlands. In clinically healthy humans and animals both the haemolytic and the non-haemolytic type of L.m. have been isolated from feces; as regards the latter type it is very questionable whether it has any pathogenic significance. When inoculating 10 days old hen's eggs the haemolytic strains will kill all embryo's within 4 days whereas all embryo's inoculated with non-haemolytic strains will survive. Both types of strains have also been isolated from waste- and surface waters. As regards epidemiological and epizootiological aspects the conclusion is warranted that continued research will be needed to get a clear picture of the course of infection of L.m. When isolating strains from contaminated material the so-called cold enrichment icubation at 4 degrees C continues to be of great value; in the course of our experiments the nalidixic-acid trypaflavine serum agar proved to be a very good selective medium. A number of stable biochemical reactions of L.m. are rather characteristic (salicine+, galactose-) but provide no clue to distinguish between haemolytic and non-haemolytic strains.

The factor VIII coagulant activity (FVIII:C), factor VIII related antigen (FVIII:RAG), and factor VIII ristocetin cofactor activity (FVIII:RCF) was determined in the cord blood samples of 30 healthy term newborns. Sodium citrate anticoagulant, cold, and a proteolytic inhibitor were used in sample processing. All three factor VIII activities were elevated in infants compared to adults; additionally, FVIII:RAG was significantly higher in vaginally compared with caesarean section delivered infants. Crossed immunoelectrophoresis of the term infant plasma showed a consistently normal factor VIII mobility. An additional group of 22 sick premature and term infants had determinations of factor VIII antigen and crossed immunoelectrophoresis. The FVIII:RAG of sick infants was approximately twice that of the well term infants. Infants with severe lung disease, asphyxia, thrombosis and sepsis had normal electrophoretic mobility despite marked elevations in FVIII:RAG. Abnormal, symmetrical, more anodal migrations were seen only in a group of severely ill newborns with dissiminated intravascular coagulation (DIC) or signs of activated fibrinolysis. These results suggest that the elevated FVIII activities seen in well infants and most sick newborns are the result of increased release of a normal form of the FVIII molecule. Those elevations seen in sick newborns with DIC result from increased release and the production of an altered, faster moving FVIII molecule.

Simple mechanical swelling of the renal parenchyma against an unyielding renal capsule may be responsible in part for the development of oliguria and acute tubular necrosis. However, until now, renal swelling was difficult to measure, except by postmortem gravimetric techniques. A new in vivo technique, the thermal dye double indicator dilution technique, was used to assess renal swelling by measuring extravascular renal water. Ice cold indocyanine green dye solution was injected rapidly into the renal artery of 5 mongrel dogs, and the thermal dilution and dye dilution curves were recorded simultaneously by means of a thermistor catheter in the renal vein. The curves were corrected for the response time of the measuring systems, then the extravascular renal water was compared (renal blood flow multiplied by the difference in mean transit times of the thermal dilution and dye dilution curves). The results were compared to the gravimetrically determined extravascular renal water. A high correlation was found to exist between the thermal dye dilution method and the gravimetric method (r = 0.92, X = 0.65 Y + 19.8, p less than 0.05). These preliminary results are encouraging and warrant further trials, inasmuch as this technique would allow the sequential in vivo measurement of renal edema. It is therefore feasible to quantitate the effect of clinical insults, such as hypovolemic shock or sepsis, on the kidney, and to assess the value of different therapeutic interventions. A small body of evidence attempts to relate the role of simple mechanical swelling of the kidney to the pathogenesis of acute renal failure.

Hypoglycemia is but one of a number of causes of hypothermia, but is important to keep in mind as a possible precipitating or concurrent event even in those cases in which there are other obvious explanations for decreased body temperature (exposure, alcoholism, starvation, sepsis or hypothyroidism). Hypoglycemia may occur in as many as 40 percent of very cold patients, and be clinically unrecognized because symptoms are masked by the hypothermia itself. Although serum glucose levels are depressed, a cold-induced renal tubular glycosuria may occur. Glucose in the urine, therefore, cannot be used as assurance of hyperglycemia in a hypothermic patient. And, although cold protects against serious end organ damage from hypoglycemia by decreasing tissue metabolic need for glucose, a serum specimen should be drawn for glucose determination in all hypothermic patients and a 50 percent glucose solution immediately given intravenously. If this is not done, serum glucose levels may plummet as the patient is rewarmed and begins to shiver.

Cold insoluble globulin (fibronectin, alpha 2-surface binding glycoprotein) is a naturally occurring substance necessary for optimal stimulation of the reticuloendothelial system. While this globulin depends on macrophages as the effector cells for its opsonic function, as is true of both antibody and complement, it is neither part of nor dependent on these systems for its opsonic activity. A relatively simple bioassay developed at the Medical College of Georgia substantiated that cold insoluble globulin is severely depleted in sepsis. Cryoprecipitate, properly processed and stored, is an exogenous source of cold insoluble globulin. Infused into septic patients 10 units thawed at 2 degrees C and reconstituted to 250 ml with saline solution can temporarily restore cold insoluble globulin levels and enhance activity of the reticuloendothelial system. Proper current use dictates measurement of cold insoluble globulin levels in the infusate as well as levels in the patient and the clinical response to infusion. Our bioassay and a septic patient's response to infusion of cold insoluble globulin are reported herein.

It has been previously demonstrated that mitochondria isolated from the livers of septic rats display an oxidative phosphorylation capability similar to that of mitochondria from normal hepatocytes. The present study was performed to determine whether this is also true at the level of the whole tissue or was perhaps the result of mitochondrial isolation. To study this, sepsis in rats was produced by cecal ligation and puncture (CLP). 16-19 hr after CLP (late sepsis) rats were sacrificed and the livers removed and placed in ice-cold Krebs Ringer's phosphate buffer. Slices less than 1-mm thick were prepared and placed in the well of a temperature controlled O2 monitor. O2 consumption by liver slices was monitored in buffer equilibrated with 100% O2 (high O2) or room air (low O2). Slices from both septic and sham-operated rats exhibited high initial rates of respiration in high O2 environment (34.3 +/- 3.4 and 31.5 +/- 2.5 microliters/min/gm, respectively). Rates of oxygen consumption were significantly lower after 20 min in high O2 and initially in low O2. Under each environmental condition there was no significant difference in O2 consumption between liver slices from sham-operated and septic rats. The decline in O2 consumption in high O2 was not reversed by resuspending in high O2 buffer but was further inhibited by KCN. These results support the view that depressed O2 consumption in late sepsis is secondary to decreased O2 delivery rather than a primary deficit in oxidative capability of the hepatocytes.
