[Infectious arteriopathies].

After reviewing the physiopathology, the authors report the principal features of infectious arterial disease observed in a department of infectious diseases. Excluding iatrogenic arteritis, particularly after vascular surgery, and some vasculitis in which an infectious agent may play a role, only the classical but now rare causes are described: rickettsial disease, syphilis and typhoid. The most commonly observed problem at present is infectious aneurysms: primary aneurysms secondary to atherosclerosis in which salmonella is by far the predominant organism, before the staphylococci and streptococci. The most serious complication is the major risk of rupture which may be the presenting event. Secondary aneurysms are essentially those of endocarditis. The mechanism is not fully understood and they occur at different stages of the course of the disease. The main problem associated with these aneurysms is their multiplicity and localisation; the intracranial forms are the most common and most serious in the experience of the authors, with their difficulties of diagnosis and treatment: extracranial aneurysms are usually located in the main limb arteries. Adjacent secondary aneurysms are exceptionally rare. Tuberculous and viral causes of aneurysm are among the rarest etiologies discussed.

[Erysipelothrix rhusiopathiae endocarditis. A case report and review of the literature].

A case of acute aortic valve Erysipelothrix rhusiopathiae endocarditis is reported in a 48 year old fisherman with no history of initial erysipelar and requiring emergency aortic valve replacement 48 hours after starting antibiotic therapy with Ampicillin and Gentamicin. The outcome was favourable. In the light of 32 of the 40 previously published cases, the authors discuss the difficulty in identifying the causal organism, the main epidemiological features, the occupational association of these infections, the incidence of primary infections, the involvement of the aortic valve and the more serious nature of the disease compared to non-D streptococcal endocarditis, despite high sensitivity to Penicillin G.

[Adenine arabinoside treatment of varicella and generalized herpes zoster in 43 immunosuppressed patients].

Forty-three immunosuppressed patients presenting with varicella or generalized herpes zoster were treated with adenine arabinoside (as monophosphate in 10 patients). All those who received the recommended 5-day course were rapidly cured without relapse; the skin lesions were virus-free after the 5th days of treatment. Five patients with malignant varicella involving several organs and who had only been treated for a few hours died. It is concluded that adenine arabinoside is a useful drug in VZ virus infections, although it has no immediate action. The monophosphate presentation, more soluble and requiring lesser amounts of solvent, is easier to administer and as effective as the ordinary presentation.

[Endocarditis due to commensal Neisseria (author's transl)].

Three cases of endocarditis due to Neisseria mucosa are reported. The pathogenic role of these commensal microorganisms is reviewed. A survey of the literature found a dozen cases of endocarditis due to commensal Neisseria before the antibiotic era, and fourteen more since then (not including our three observations). Some of distinctive features can be delineated from the study of cases seen during the second period. Patients mean age is fairly low (34 years), incidence of cutaneous manifestations is high, and vascular complications (mainly embolism) are common (52, 1% of the cases). Overall prognosis is good and the recovery rate (82 %) is similar to that seen in non-D Streptococcus endocarditis.

[Controlled study of pristinamycin versus oxacillin in staphylococcal infections ].

A prospective double-blind study was conducted in patients hospitalized with a staphylococcal infection. The effects of oxacillin (4-6 g/d) and pristinamycin (2-3 g/d) were compared. These were 52 cutaneous infections and 17 other ones. The results of the two antibiotics effects were not different. Tolerance was appreciated in the 82 patients who entered the study: pristinamycin had fewer (but not significantly different) side effects than oxacillin (3/37 vs 9/45). As pristinamycin is active in vitro on at least 95 p. cent of strains, we concluded that it can be the first choice antibiotic in staphylococcal infections when the oral route is possible.

[Bacterial endocarditis : lack of diagnostic value of immunological investigations (author's transl)].

To evaluate the diagnostic help afforded by immune determinations in feverish valvular patients, we prospectively determined: total hemolytic complement, cryoglobulin, rheumatoid factor, circulating immune complexes and direct skin immunofluorescence. Twenty patients entered the study, twelve with bacterial endocarditis, six without any bacteremia and two septicemic patients without endocarditis. We detected at least one immune abnormality in 10/12 endocarditis patients: - in 7/11 (64 p. cent) circulating immune complexes; - in 3/12 rheumatoid factor; - in 3/12 positive fluorescence in dermal vessels (IgM-C3); - and in one patient an IgG lupus-like band in the membrane basal zone. We also found circulating immune complexes in 3/4 patients without bacteremia and in 1/2 septicemic patients. We conclude that, in our small prospective study, immune abnormalities are frequent in bacterial endocarditis patients but their diagnostic values is rather limited : their absence do not rule out endocarditis and they can be present in many other febrile disorders.

[Plasmodium falciparum malaria resistant to polychemotherapy. Usefulness of pathogen culture (author's transl)].

In a patients with P. falciparum malaria contracted in Thailand, the course of the disease under treatment suggested resistance to both chloroquine and pyrimethamine-sulfadoxine, as well as reduced sensitivity to quinine. This was confirmed by in vitro tests on continuous culture of the strain. Therapeutic success was obtained with a quinine-cycline combination. The problems raised by the emergence of P. Falciparum strains resistant to polychemotherapy are emphasized.
