RESUMEN

BACKGROUND: Monkeypox virus (MPXV) is currently spreading among men who have sex with men, outside of sub-Saharan Africa, and close contact during sex seems to be one of the key pathways of viral transmission in the current outbreak. Our aim was to describe the distribution of MPXV in the human body, as it might play a role in its dissemination through sexual contact. METHODS: The study population in this case series consisted of patients with confirmed MPXV infection attending the Pitié-Salpêtrière Hospital (Paris, France), who had been sampled from multiple anatomical sites, including skin, anus, throat, blood, urine, and semen, at diagnosis and 2 weeks later. We compared the proportion of positive samples and MPXV viral loads (given as PCR cycle thresholds [Ct]) between anatomical sites, and between day 0 (D0) and D14. FINDINGS: Overall, 356 samples were collected between May 20 and June 13, 2022, from 50 men with a median age of 34 years (IQR 29-40). 22 (44%) of the 50 men were classified as HIV-negative on day (D)0, and 22 (44%) were living with HIV. At D0, MPXV detection was more frequent from skin (44 [88%] of 50), anus (30 [71%] of 42), and throat (36 [77%] of 47) than from blood (13 [29%] of 45), urine (nine [22%] of 41), or semen (13 [54%] of 24). Viral loads were significantly higher from skin lesions (Ct 19·8) and anal samples (Ct 20·9) than from throat (Ct 27·2), blood (Ct 32·8), urine (31·1), or semen samples (Ct 27·8). When analysing the 107 samples taken from 24 patients at D14, the proportion of positive samples strongly decreased between D0 and D14 at all sites: skin (four [22%] of 18), anus (two [9%] of 22), throat (none of 21), blood (one [5%] of 21), urine (none of 14), and semen (two [9%] of 11). INTERPRETATION: These data contribute to a better understanding of how the virus might spread between sexual partners over a relatively short period of time. High MPXV viral loads from skin and mucosa, including genital and anal sites, suggest that transmission most likely occurs through direct body contact rather than through the respiratory route or contact with body fluids, which should help to refine the prevention messages delivered to individuals most exposed to the virus. FUNDING: None.

RESUMEN

OBJECTIVES: We report the characteristics of Mycoplasmagenitalium (MG) infection in patients from a STI center in Paris. We evaluated outcomes after treatment. METHODS: We included all patients tested for MG, Chlamydiatrachomatis (CT) and Neisseria gonorrhoeae (NG) infection in our center from January 2017 to December 2018, using multiplex PCR on urine specimen, vaginal or rectal swabs. We collected data regarding sex, age, HIV status, PrEP use, sexual behavior, NG and CT co-infection, symptoms and treatment. RESULTS: MG infection prevalence was 7% (397/5586) (95% CI 6.4-7.8). It ranged from 4.6% in patients consulting for routine STI testing (3.9% in women, 5% in men), to 16% in HIV-positive patients and 25% in PrEP users. Among the 397 MG infected patients, 351 (88%) were asymptomatic and 87 (22%) were co-infected with NG or CT. Among the 270 (68%) treated patients, 249 (92%) received azithromycin. Failure rate was 74% in the 103 patients tested post-treatment. Treatment failure tended to be higher with azithromycin single dose than with 5-day azithromycin (88% vs. 70%; P=0.07). Azithromycin and moxifloxacin were used as second-line treatment in 24 and 23 patients, respectively. Post-treatment PCR remained positive in 55% of the 44 tested patients with a better eradication rate with moxifloxacin than with azithromycin (70% vs. 33%; P=0.04). CONCLUSION: MG infection is highly prevalent in PrEP users and HIV-positive patients and is mostly asymptomatic. Management of MG infection should be tailored and adapted to the risk of antibiotic resistance and reinfection.

RESUMEN

BACKGROUND: We report a case of subdural empyema in a homeless patient caused by Bartonella quintana. B. quintana is a facultative intracellular bacteria for which bacterial growth is fastidious. The molecular biology approach has been a real help in establishing the diagnosis. CASE REPORT: A 59-years old homeless patient, with a history of chronic alcohol abuse, was brought to the emergency department with a massive subdural empyema. Extensive microbiological evaluation didn't reveal any pathogen in the pus collected before antibiotic treatment. B. quintana was detected in the pus from the empyema using a 16S rRNA-based PCR. Histology of intraoperative samples was consistent with the diagnosis and a serological assay was positive. The patient responded well to a treatment that included craniectomy with drainage of the loculated pus, total removal of the infected capsule and a combination of antibiotics. CONCLUSION: This unique case of B. quintana-related empyema illustrates the risk of secondary infection of subdural hematoma with B. quintana since such infections have recently reemerged, predominantly among the homeless populations. Patients with subdural empyema in at-risk populations should be systematically evaluated for B. quintana with an appropriate diagnostic approach involving molecular biology.
