Clinical aspects on 64 cases of juvenile and adult listeriosis in Sweden.

In 1958-74 altogether 64 cases of bacteriologically verified infections of Listeria monocytogenes were diagnosed in Sweden in children, aged more than 27 days, and in adults. Immunosuppression predisposed to the disease. Thus, many patients had co-existing disorders, such as leukemia and alcoholism. Sixteen patients had been treated with corticosteroids, which were combined with cytostatic drugs in nine. Meningoencephalitis was diagnosed in 52 patients and was fatal in 16. The clinical symptoms did not differ from those in purulent meningitis caused by other bacteria. In the cerebrospinal fluid the cellular response was dominated by polymorphonuclear cells in 29 patients and by mononuclear cells in 20. Ten patients had septicemia, which was fatal in four. Clinical symptoms were dominated by chills, high fever and general prostration. One patient had pleurisy and one an abscess of the neck; both recovered. Serotypes 1 and 4b prevailed and were equally common. Many patients developed raised antibody titers in both the O-agglutination test and the complement fixation test. The titers were often not positive until after a month. Moderate granulocytosis was the rule and monocytosis was rarely seen. Ampicillin alone or combined with an aminoglycoside seemed to be the drug of choice in the treatment of listeriosis. An alternative drug was tetracycline. Most deaths occurred within six days of onset of the illness. Early diagnosis and treatment were imperative. Most patients recovered and serious sequelae were rare.

Influence of cytostatics on some platelet functions in vitro. V. Hydroxyurea.

Hydroxyurea added to citrated platelet-rich plasma in vitro did not influence the aggregation of the platelets, their adhesion to glass, their release of aggregating activity, platelet factor 4 or availability of platelet factor 3. Neither did it have any effect on the uptake of 14C-serotonin, the reptilase clot retraction or the coagulation system.

Mechanism of calcium-induced reptilase clot retraction.

Calcium ions induce retraction of reptilase clots. This could also be induced by thrombin. Heparin inhibited the reptilase clot retraction induced either by thrombin or calcium, but did not influence the clot retraction induced by ADP. This indicated that the clot retraction induced by Ca2+ was mediated by an activation of the coagulation system with the formation of thrombin.
