Hepatitis E virus (HEV): seroprevalence and HEV RNA detection in subjects attending a sexually transmitted infection clinic in Brussels, Belgium.

Men who have sex with men (MSM) have an increased incidence of pathogens transmitted by the oro-fecal route. Hepatitis E virus (HEV) is an emerging cause of acute hepatitis and fecal shedding is observed during primary infection. We investigated whether MSM are at increased risk of HEV infection. Subjects who attended a sexually transmitted infection clinic in Brussels and had an HIV test performed between 1 June 2014 and 15 January 2016 were identified. A total of 576 samples were retrospectively screened for both total HEV IgG and HEV RNA. Samples positive for IgG were tested for IgM. MSM proportion was 31·1% (179/576). Overall HEV IgG prevalence was 9·03% (52/576) and was identical in MSM and heterosexual subjects. Among the IgG positive samples, 2/52 (3·84%) samples (both women) were positive for anti-HEV IgM. No sample was positive for HEV RNA. Age over 35 was the only risk factor significantly associated with HEV seropositivity (OR 2·07; 95% CI 1·16-3·67). In conclusion, MSM were not found to have an increased prevalence of HEV as previously reported in other European countries suggesting distinct dynamics of HEV infection in this group across Europe and increased age was associated with a higher risk of seropositivity.

Drug-induced uveitis in aids patients: two case reports.

Patients with acquired immunodeficiency syndrome (AIDS) can develop severe uveitis. Although infectious and autoimmune causes must always be considered, drug induced uveitis is also an important etiology. Herein, we present two case reports illustrating the classical presentation of rifabutin and cidofovir induced uveitis. The first case was a 33 year old woman with AIDS treated with anti-protease and anti-tuberculosis drugs (including rifabutin). She presented with a red painful right eye. There was a strong anterior segment inflammation with fibrinous exudates and a dense vitritis. Rifabutin was stopped and topical steroids and mydriatics were given. Intraocular inflammation and symptoms rapidly resolved. The second patient was a 36 year old woman who presented with a painful decrease of vision in her left eye. She was followed for bilateral CMV retinitis in the setting of AIDS and had recently received 2 systemic injections of cidofovir. Anterior segment inflammation with posterior synechiae in both eyes and folds of Descemet membrane in the left eye were noted. Intraocular pressure was 0 mmHg in the left eye and 10 mmHg in the right eye. Fundus examination disclosed CMV retinitis scars in the right eye and choroidal folds in the macula of the left eye. Cidofovir was discontinued and topical steroids and mydriatics started. Progressively the inflammation decreased and the intraocular pressure returned to normal levels. In conclusion, rifabutin and cidofovir are classical examples of drug induced uveitis with distinct characteristic clinical presentation. Recognition of those entities in AIDS patients can avoid useless and potentially invasive interventions in those fragile people.

Neurosyphilis cerebrospinal fluid findings in patients with ocular syphilis.

Purpose: To evaluate neurosyphilis cerebrospinal fluid (CSF) findings and initial ophthalmic manifestations in patients with syphilitic uveitis.Methods: We retrospectively reviewed the records of CSF analysis of 14 patients with syphilitic uveitis with treponemal analysis - chemiluminescent immunoassay and TPHA- and non-treponemal analysis - Rapid Plasma Reagin test - RPR.Results: 86% were males and 43% HIV+. Ocular signs of syphilis lead to the diagnosis of syphilis in 78% of patients. Typical syphilitic uveitis presentations included: acute syphilitic posterior placoid chorioretinitis (50% of patients), retinitis (21% of patients) and punctate inner retinitis (7% of patients). 57% of patients had definite neurosyphilis by the CDC criteria, while 71% had CSF abnormalities suggestive of central nervous system involvement.Conclusion: Based on international guidelines, the frequent CSF abnormalities found in syphilitic uveitis patient supports the diagnosis of neurosyphilis in a majority of patients.

[News in the treatment of sexually transmitted diseases]. / Actualités dans le traitement des infections sexuellement transmissibles.

Most important news are the reimbursement of post-exposure prophylaxis for HIV, change in treatment of gonococcal infections, increase of syphilis and sexually transmitted hepatitis C infections among HIV-infected men who have sex with men. Vaccination against papillomavirus (HPV) is not discussed here. Animal and human studies have shown that 28 days post-exposure prophylaxis for HIV initiated within 72 hours after the contact at risk could reduce the risk of HIV acquisition. This prophylaxis is now reimbursed in Belgium if it is prescribed by a HIV reference center, based on the Belgian consensus for HIV post-exposure prophylaxis. A single intramuscular dose of ceftriaxone 125 mg is now the best choice for the treatment of gonococcal infection, due to the resistance more and more frequent to penicillin, tetracycline and fluoroquinolone. If a concomitant infection with Chlamydia trachomatis has not been ruled out, a single dose of azithromycin 1 g or doxycycline for 7 days will be added. Syphilis is shortly reviewed and addresses of few very useful Internet sites are given.

First case of Campylobacter rectus and Solobacterium moorei mixed bacteraemia successfully identified by MALDI TOF-MS.

Campylobacter rectus and Solobacterium moorei are anaerobic Gram-negative and Gram-positive rods, respectively, that are occasionally members of the human oral flora. Bacteraemia has rarely been reported. We present the first case of mixed C. rectus-S. moorei bacteraemia in an individual with diabetes and human immunodeficiency virus infection. Both bacteria were successfully identified by MALDI-TOF MS.

[Mediastinal mass, pulmonary infiltration, and meningitis]. / Masse médiastinale, infiltrat pulmonaire et méningite.

A 42 year-woman suffering from a non-small cell lung cancer, presenting initially as a mediastinal tumor, is hospitalized for fever, headaches and nausea. An aseptic meningitis is diagnosed. The patient died despite the administration of broad spectrum antibiotics and antituberculous agents. The differential diagnoses are presented.

Risk factors of osteopenia in HIV-infected women: no role of antiretroviral therapy.

OBJECTIVES: Osteopenia and osteoporosis are more frequent in HIV-infected patients. Whether antiretroviral therapy induces a bone mineral density (BMD) loss remains controversial and few data are available in women. This cross-sectional study of 89 pre-menopausal HIV-infected women evaluates the relationship between BMD and antiretroviral treatment. METHODS: Three groups of women were compared: women never treated (n=37), women treated with nucleoside reverse transcriptase inhibitors and non-nucleoside reverse transcriptase inhibitors and never treated with protease inhibitor (PI) (n=25) and women treated with a PI-containing regimen (n=27). Their lumbar spine and hip BMD was measured by dual-energy X-ray absorptiometry. We assessed also demographic parameters, body mass index (BMI), habits, history of HIV infection and treatment, lipodystrophy and metabolic and hormonal parameters. RESULTS: 83% were African women. Mean age was 37 years. Median duration of HIV treatment was 3.5 years. The overall prevalence of osteopenia/porosis was 31.5%. No difference was found between the three groups. Using logistic regression, low BMI was the only factor associated with osteopenia/porosis. CONCLUSION: Osteopenia/porosis was highly prevalent among these HIV-infected pre-menopausal women, mainly of African origin. BMD loss was not associated with antiretroviral therapy (containing PI or not) but was associated with a low BMI.
