[Update of Chlamydia trachomatis infection]. / Infection à Chlamydia trachomatis : mise au point.

Chlamydia trachomatis (CT) is the most common sexually transmitted bacterial infection worldwide. It is asymptomatic in most cases and mainly affects young women, with potential long term sequelae (pelvic inflammatory disease, tubal infertility, obstetric complications). The impact on male fertility is controversial. Screening methods as well as antibiotics use have recently been reassessed due to resistance phenomena and the negative effect on the urogenital microbiota. Positive CT serology may be indicative of tuboperitoneal pathology, which may not be noticed on hysterosalpingography. New research on single-nucleotide polymorphisms (SNPs) aims to establish a patient profile at higher risk of infectious tubal damage due to CT. CT seropositivity is also associated with decreased spontaneous pregnancy rates and is a predictive factor for obstetrical complications.

Invasive rhino-orbital-cerebral aspergillosis in an immunocompetent patient.

INTRODUCTION: Rhino-orbital-aspergillosis (ROA) is a rare but serious disease in immunocompetent patients. Diagnosis is often delayed due to the absence of specific clinical symptoms. We describe the case of a patient who presented initially with ROA which spread progressively to the right ethmoid-sphenoid sinuses and then to the brain. OBSERVATION: A 61-year-old patient with a history of well-controlled diabetes presented with a sudden severe decrease in right visual acuity. Cerebral MRI showed the presence of an infiltrate in the right orbital apex extending to the homolateral cavernous sinus without any cerebral involvement. A diagnosis of right orbital myositis was made and corticosteroid therapy was started. His symptoms worsened progressively leading to quasi-blindness. A new MRI showed the development of right sphenoid-ethmoid osteolytic lesions. A fungal aetiology was suspected and tests for fungal biomarkers found a ß-(1-3)-D-glucan level of 99pg/ml but negative galactomannan. An ethmoid biopsy was performed for histological and mycological investigations, including the detection of Aspergillus DNA by qPCR. qPCR was positive and culture resulted in the isolation of multi-sensitive Aspergillus fumigatus. Treatment was initiated with voriconazole. Due to persistence of blindness and the appearance of a lesion extending to the right frontal lobe, surgical excision was performed followed by antifungal treatment for a total duration of 1year. The patient is currently stable, but has persistence of blindness in the right eye. CONCLUSION: Invasive ROA is a rare but serious disease in immunocompetent patients which should be evoked in the differential diagnosis of a tumour or vasculitis. Early diagnosis is essential for optimal management.

Proposal for shorter antibiotic therapies.

OBJECTIVES: Reducing antibiotic consumption has now become a major public health priority. Reducing treatment duration is one of the means to achieve this objective. Guidelines on the therapeutic management of the most frequent infections recommend ranges of treatment duration in the ratio of one to two. The Recommendation Group of the French Infectious Diseases Society (SPILF) was asked to collect literature data to then recommend the shortest treatment durations possible for various infections. METHODS: Analysis of the literature focused on guidelines published in French and English, supported by a systematic search on PubMed. Articles dating from one year before the guidelines publication to August 31, 2015 were searched on the website. RESULTS: The shortest treatment durations based on the relevant clinical data were suggested for upper and lower respiratory tract infections, central venous catheter-related and uncomplicated primary bacteremia, infective endocarditis, bacterial meningitis, intra-abdominal, urinary tract, upper reproductive tract, bone and joint, skin and soft tissue infections, and febrile neutropenia. Details of analyzed articles were shown in tables. CONCLUSION: This work stresses the need for new well-conducted studies evaluating treatment durations for some common infections. Following the above-mentioned work focusing on existing literature data, the Recommendation Group of the SPILF suggests specific study proposals.

Cefoxitin: An alternative to carbapenems in urinary tract infections due to extended-spectrum beta-lactamase-producing Enterobacteriaceae.

BACKGROUND AND OBJECTIVES: Infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) have become a major public health issue worldwide. Cefoxitin is a second-generation cephalosporin and is associated with a strong in vitro activity against ESBL. PATIENTS AND METHODS: We conducted a prospective monocentric cohort study from 2012 to 2015 to evaluate the clinical efficacy and safety of cefoxitin in 15 patients treated for urinary tract infection (UTI) caused by ESBL-E, without any severity criteria. RESULTS: We included 15 patients; 11 were male patients with defined risk factors for ESBL-E. Ten patients presented with male UTI, three with pyelonephritis, and two with cystitis. Escherichia coli was the predominant pathogen. All patients had a positive outcome with a good tolerance (a skin rash without any sign of severity was observed in one patient). Microbiological cure was obtained in 9 patients out of 10 at the end of treatment. CONCLUSION: Cefoxitin is an alternative treatment to carbapenems for urinary tract infections caused by ESBL-producing Enterobacteriaceae.

[Could a resident be a remote infectious disease specialist consultant? The Lille teaching hospital experience]. / Faut-il mettre un interne en infectiologie transversale ? L'expérience au centre hospitalier régional et universitaire de Lille.

Infectious diseases specialist consultants are usually senior physicians. At the Lille University Hospital, it was decided to associate an infectious disease (ID) resident to this remote infectious disease activity to improve his training in this field. He visited the emergency department daily, participated in weekly multidisciplinary meetings with medical staff, and was in first line to answer the phone which is the usual means for hospital doctors to ask specific questions. It was a very instructive experience for an ID resident because of the diversity of clinical cases in other departments and he often had to refer to medical literature. However, being a remote consultant could be difficult for an ID resident. He might be less well considered than a senior physician by the other specialists. To conclude, a remote infectious disease consultant can be an ID resident if he is experienced and supervised by a senior physician.

[Pseudoxanthoma elasticum-like syndrome associated with hemoglobinopathy: a case report]. / Syndrome pseudoxanthome élastique like et drépanocytose: à propos d'un cas ?

INTRODUCTION: We report a case of hemoglobinopathy which could be associated with a pseudoxanthoma elastic-like syndrome. EXEGESIS: We report the case of a 26-year-old male patient with sickle cell anemia for which the supra-aortic-doppler ultrasonography suggested an asymptomatic left carotid artery of 70% stenosis. The magnetic resonance imaging and angiography showed a left megadolichocarotid with plicature suggestive of pseudoxanthoma elastic or a dilatation relative to a high rate of blood explaining the acceleration speed. There was a cutaneous infiltration but other vasculopathies of neither carotide, nor cerebral, nor ocular have been discovered while they were sometimes found in pseudoxanthoma elastic-like syndrome. This acquired form is different of rare hereditary disease by a later diagnosis, a clinical expression often very incomplete and a frequent association with hemoglobinopathies. CONCLUSION: This observation shows that RMA could be necessary to perform in adults, when cervical and transcranial Doppler ultrasonography is abnormal, particularly before deciding to start long term blood transfusions. The hemoglobinopathy and pseudoxanthoma elastic-like syndrome must not be ignored because the control of cardiovascular factors reduce the risks of arterial complications.

[MPO-ANCA related vasculitis presenting as chronic iron deficiency anemia due to paucisymptomatic intra-alveolar haemorrhage]. / Micropolyangéite révélée par une anémie d'évolution chronique secondaire à une hémorragie intra-alvéolaire paucisymptomatique: à propos d'un cas.

INTRODUCTION: An alveolar haemorrhage occurs in 12 to 29% during microscopic polyangeitis and can reveal this disease. EXEGESIS: We report the case of a fifteen years old female patient with a microscopic polyangeitis which was diagnosed during the investigation of a chronic anemia with chronic asymptomatic alveolar haemorrhage and extracapillary glomerulonephritis with antineutrophil cytoplasmic antibodies positive (anti-myeloperoxydase antibodies). The good tolerance of alveolar haemorrhage is usual for children, particularly in idiopathic pulmonary haemorrhage but is exeptionnal for adults. According to some studies, thirty percent of idiopathic pulmonary haemorrhage goes to auto-immune disease. CONCLUSION: This observation shows that complementary pulmonary investigations are necessary in chronic anemia when gynaecologic and digestive investigations are negative and that auto-immune investigations are judicious in the survey of idiopathic pulmonary haemorrhage.
