In a large population of children, common clinical and laboratory admission parameters were identified that can help predict the risk for an invasive bacterial infection. These results encourage the possibility of a more selective management strategy for these children.

Three hundred and forty-six serum samples taken between 1998 and 2000 from urban stray cats in the city of Ghent were tested for antibodies to Toxoplasma gondii and feline immunodeficiency virus (FIV), and antigens of feline leukemia virus (FeLV). Of these 346 samples, 243 (70.2 per cent) were seropositive for Tgondii. Thirty-nine cats (11.3 per cent) had antibodies against FIV and 13 (3.8 per cent) had circulating antigens of FeLV. Fewer of the female cats had FIV and heavier cats had a higher seroprevalence of FIV. Exact logistic regression showed that cats that were infected with FIV were more likely to be infected with T gondii (P = 0.04), and the cats with FIV had a higher titre of Tgondii antibodies than FIV-negative animals. However, FeLV was not associated with either T gondii or FIV.

Age > or =12 years and admission or 24-hour values of CRP > or =90/100 mg/L and IL-8 > or =200/300 pg/mL are predictors of sepsis not clinically apparent during the first 24 hours of hospitalization.

We identified early clinical and laboratory findings significantly associated with death occurring at a later stage. Routine evaluation of these variables may prove to be useful in the early identification of children with a high-risk FN episode at risk for death.

Fever persisting at day 4 of admission, together with AMC < or =100 and CRP > or =90 significantly increased the risk for IFD in children with cancer.

Background Mycoplasma genitalium (MG) is an emerging pathogen among men who have sex with men (MSM) with raising rates of antibiotic resistance. In this study, we assessed the prevalence and incidence of MG infection in MSM enrolled in the open-label phase of the ANRS IPERGAY trial with on demand TDF/FTC for HIV prevention and the impact of doxycycline post-exposure prophylaxis (PEP). Methods 210 subjects were tested at baseline and at 6 months by real-time PCR assays for MG detection in urine samples, oro-pharyngeal and anal swabs. Resistance to azithromycin (AZM), to fluoroquinolones (FQ) and to doxycycline were investigated in the French National Reference Centre of bacterial STI. Results The all-site prevalence of MG at baseline was 10.5% [6.3% in urine samples, 4.3% in anal swabs and 0.5% in throat swabs] and remained unchanged at 6 months whether or not PEP was used: 9.9% overall, 10.2% with PEP and 9.6% without. The overall rate of MG resistance (prevalent and incident cases) to AZM and FQ was 67.6% and 9.1%, respectively, with no difference between arms. An in vivo mutation of the MG 16S rRNA which could be associated with tetracycline resistance was observed in 12.5% of specimens tested. Conclusions The prevalence of MG infection among MSM on PrEP was high and its incidence was not decreased by doxycycline prophylaxis with a similar high rate of AZM- and FQ-resistance, raising challenging issues for the treatment of this STI and supporting current recommendations to avoid testing or treatment of asymptomatic MG infection.

We evaluated the efficacy of a vancomycin solution in the prevention of bacteremia caused by vancomycin‐sensitive organisms (VSO) in cancer patients with a tunneled central venous catheter (CVC). Eighty‐three patients who had a single lumen CVC were randomized to use a heparin solution (25 U/ml) for daily catheter flush with (HepVan) or without (Hep) vancomycin, 25 mcg/ml. Febrile episodes were recorded, and central and peripheral blood cultures were drawn before beginning antibiotic therapy. Patients participated in follow‐up for 16,677 catheter days (8,666 Hep and 8,011 HepVan), and 143 febrile episodes were recorded (82 Hep and 61 HepVan). Forty‐four episodes of bacteremia occurred, 23 of them due to VSO (16 occurred in the Hep group and 7 in the HepVan group (P = 0.19). VSO bacteremia occurred in 14 neutropenic (absolute neutrophil count < 500 × 104/l) episodes (7 Hep vs. 7 HepVan) and in 9 non‐neutropenic episodes (9 Hep vs. 0 HepVan; P = 0.013). Vancomycin effectively prevented bacteremia by VSO in non‐neutropenic patients, supporting the idea that intraluminal colonization of indwelling CVCs contributes to bacteremia only in these patients.
