ABSTRACT
OBJECTIVES: To study valve appearance and the presence of valve disease in a cohort of people living with HIV (PLHIV). DESIGN: A prospective study of PLHIV examined at the cardiology department of the Clermont Ferrand university hospital group (CHU) between January 1, 2012, and December 31, 2014. Were excluded those with a history of infection associated with a possible endocarditis. METHODS: Demographic, medical characteristics and cardiovascular disease risk factors at time of cardiovascular examination and Doppler-echocardiography were recorded and analyzed. RESULTS: In total, 903 PLHIV were examined in the infectious diseases department, 255 of whom were included. These consisted of 67 women (26.3%) and 188 men, of a mean age of 51.2±9.7years, in whom coronary artery disease was diagnosed in 18 patients (7.0%), two women and 16 men, representing a prevalence of 3.0% in females and 8.5% in males. The appearance of the aortic cusps was considered dystrophic in 14.1% of cases (36/255), dysplastic in two cases (0.8%), exhibiting a bicuspid deformity in one case. The prevalence of aortic valve abnormality was therefore 6.0% in the women (4/67) and 17.0% in the men (32/188). On facing off this data with the Kora Monica study findings, an increase in prevalence appears only to truly manifest after 50years of age. We registered 35 aortic insufficiency cases (13.7%), representing a higher incidence than that of the Framingham cohort, with age and masculine gender being the determining factors. CONCLUSION: Valve disease, along with coronary artery disease, should be closely monitored in PLHIV.

The first French outbreak of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) USA300 clone was investigated. After outbreak investigation, hygiene measures were implemented in all family households and childminders' homes. Several decontamination procedures were performed, which used a combination of topical mupirocin, total body application of chlorhexidine, chlorhexidine gargle (if >6 years old) and a course of antibiotic therapy in cases of infection or decontamination failure. Patients were followed up for MRSA skin and soft tissue infections (SSTIs) and carriage. Strains were characterised by antimicrobial drug resistance profile, pulsed-field gel electrophoresis (PFGE) and DNA microarrays. Between June 2011 and June 2012, six children and six adults among the ten corresponding relatives developed 28 SSTIs. None of the family members, including the index case, had any contact with foreigners or individuals known to have SSTIs. After infection control measures and prolonged decontamination have been implemented with a high adherence, six patients remained sustained CA-MRSA USA300 carriers, including one who developed mupirocin resistance and six who experienced minor CA-MRSA-related SSTIs. A baby was identified as an MRSA carrier 2 months after delivery. CA-MRSA decontamination using mupirocin and chlorhexidine in the community setting may also be a questionable strategy, associated with failure and resistance to both agents. Close monitoring of CA-MRSA SSTIs is required in France and in other European countries where MRSA USA300 has recently emerged. We showed that a closed management based on hygiene measures reinforcement, decolonisation and extended screening may fail to suppress CA-MRSA carriage and subsequent infections.
