[Anticoagulant treatment of venous thromboembolic disease: optimal duration of antivitamin K therapy. Review of the literature].

Every clinician managing a patient with venous thromboembolism of the lower limbs is faced with two opposing problems: first the risk of antivitamin K induced haemorrhage requires adequate but not excessive hypocoaguability of limited duration (international normalized ratio between 2 and 3); second the threat of recurrence requiring an adequate level of hypocoaguability of sufficient duration. Recently reported clinical data have greatly changed management attitudes. Current recommendations favour a 6 week regimen of antivitamin K for distal venous thrombosis in patients with thromboembolism of lower limb veins without any other aggravating factor and a 12 week regimen for proximal vein thrombosis or pulmonary emboli, although the therapeutic efficacity and risk remain to be demonstrated with precision. In France, we are conducting a multicentric controlled study with sufficient power (1800 patients) comparing parallel groups of patients: those with distal deep venous thrombosis treated 6 versus 12 week regimens, those with proximal deep venous thrombosis and/or pulmonary emboli treated 12 versus 24 week regimens. The "DOTAVK" study (Durée Optimale du Traitement Antivitamine K) involves patients with first time venous thrombosis or pulmonary emboli and no underlying neoplasia or coagulation disease. The two criteria of outcome are haemorrhage complications and thromboembolic recurrence during treatment and the first year after treatment withdrawal.

[Neuromeningeal listeriosis in adults. Clinical aspects and contribution of cotrimoxazole in monotherapy].

A series of 28 patients suffering from neuromeningeal listeriosis is reported. This disease is consecutive to infection by Listeria monocytogenes--an ubiquitous and opportunistic Gram-positive bacillus--and has become a public health problem: its incidence is increasing and its prognosis is very severe despite the development of new bacteriological identification methods. Human beings are contaminated by food, which explains the frequent outbreaks of epidemics which are widely publicized, the infection being one of the consequences of the unprecedented development of the food industry and the cold food chain. The predominant clinical picture is one of non-specific meningoencephalitis. In about 50 percent of the cases the subjects infected are "immunodepressed" and/or more than 60 years' old. The diagnosis is difficult since the bacteriological identification is delayed (direct examination of the cerebrospinal fluid is rarely positive) and this fluid may be sterile (hence the value of blood cultures). A probability treatment therefore must be initiated before the diagnosis is confirmed if an unfavourable outcome is to be avoided. In Listeria monocytogenes infection cotrimoxazole administered alone seems to be a better antibacterial therapy than the reference ampicillin-aminoside combination.

[Neutropenia during treatment with fusidic acid: analysis of 5 cases].

Two cases of moderate neutropenia and 3 cases of severe neutropenia in the course of fusidic acid treatment for sepsis related to a hip prothesis or septic osteitis are reported. Neutropenia was always observed following routine blood cell count, after a mean of 21 days' treatment (16 to 27 days). Moderate fever was observed only once, in a patient with profound neutropenia. A complete recovery of blood cell count was noted in all cases, 5 to 9 days upon discontinuation of fusidic acid. A sternal bone-marrow aspiration was performed in 4 cases, showing normocellularity or hypercellularity in two cases, and moderate hypoplasia of granulocytic cells. The respective roles of other treatments are discussed. Overall, these five cases suggest that reversible granulocytopenia can be caused by protracted treatment with fusidic acid. Although nine different associated drugs could also have been involved in four patients, the causal relationship was less suggestive for three of them due to chronological events. In other cases, the drugs never or very rarely caused neutropenia. Finally, the possibility of vancomycin-induced neutropenia cannot be excluded in one case.
