Effective Treatment of Lymphogranuloma venereum Proctitis With Azithromycin.

BACKGROUND: Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis (CT) serovars L1, L2, and L3 and is endemic among men who have sex with men (MSM) in Europe. We evaluated weekly oral azithromycin 1 g for 3 weeks as a treatment for LGV proctitis. METHODS: This is an open clinical trial with convenience allocation according to treating physician preferences. Adults with clinical proctitis received a single dose of 1 g of intramuscular ceftriaxone and were subsequently allocated to receive (i) doxycycline 100 mg twice daily for 21 days (Doxycycline group) or (ii) azithromycin 1 g orally once weekly for 3 weeks (Azithromycin group). LGV cure (primary endpoint) was defined as resolution of symptoms at week 6 (clinical cure, LGV-CC), with an additional supporting negative rectal polymerase chain reaction (PCR) at week 4 (microbiological cure, LGV-MC), if available. RESULTS: One hundred and twenty-five individuals with LGV clinical proctitis were included. All were MSM, and 96% were living with human immunodeficiency virus (HIV). Eighty-two were in the Azithromycin group, and 43 were in the Doxycycline group. LGV cure on a modified intention-to-treat analysis (primary endpoint), occurred in 80 of 82 (98%) in the Azithromycin group versus 41 of 43 (95%) in the Doxycycline group (treatment difference [95% confidence interval {CI}] 2.2% [-3.2, 13.2]). LGV-MC occurred in 70 of 72 (97%) vs 15 of 15 (100%) in the Azithromycin group and Doxycycline group, respectively (treatment difference [95% CI] -2.8% [-9.6; 17.7]). Adverse events were similar in both treatment groups. CONCLUSIONS: Our findings support extended azithromycin dosing as an alternative treatment option for symptomatic LGV proctitis and provides the rationale for future randomized trials.

Improved detection and management of advanced HIV disease through a community adult TB-contact tracing intervention with same-day provision of the WHO-recommended package of care including ART initiation in a rural district of Mozambique.

INTRODUCTION: AIDS-mortality remains unacceptably high in sub-Saharan Africa, largely driven by advanced HIV disease (AHD). We nested a study in an existing tuberculosis (TB) contact-tracing intervention (Xpatial-TB). The aim was to assess the burden of AHD among high-risk people living with HIV (PLHIV) identified and to evaluate the provision of the WHO-recommended package of care to this population. METHODS: All PLHIV ≥14 years old identified between June and December 2018 in Manhiça District by Xpatial-TB were offered to participate in the study if ART naïve or had suboptimal ART adherence. Consenting individuals were screened for AHD. Patients with AHD (CD4 < 200 cells/µL or WHO stage 3 or 4) were offered a package of interventions in a single visit, including testing for cryptococcal antigen (CrAg) and TB-lipoarabinomannan (TB-LAM), prophylaxis and treatment for opportunistic infections, adherence support or accelerated ART initiation. We collected information on follow-up visits carried out under routine programmatic conditions for six months. RESULTS: A total of 2881 adults were identified in the Xpatial TB-contact intervention. Overall, 23% (673/2881) were HIV positive, including 351 TB index (64.2%) and 322 TB contacts (13.8%). Overall, 159/673 PLHIV (24%) were ART naïve or had suboptimal ART adherence, of whom 155 (97%, 124 TB index and 31 TB-contacts) consented to the study and were screened for AHD. Seventy percent of TB index-patients (87/124) and 16% of TB contacts (5/31) had CD4 < 200 cells/µL. Four (13%) of the TB contacts had TB, giving an overall AHD prevalence among TB contacts of 29% (9/31). Serum-CrAg was positive in 4.6% (4/87) of TB-index patients and in zero TB contacts. All ART naïve TB contacts without TB initiated ART within 48 hours of HIV diagnosis. Among TB cases, ART timing was tailored to the presence of TB and cryptococcosis. Six-month mortality was 21% among TB-index cases and zero in TB contacts. CONCLUSIONS: A TB contact-tracing outreach intervention identified undiagnosed HIV and AHD in TB patients and their contacts, undiagnosed cryptococcosis among TB patients, and resulted in an adequate provision of the WHO-recommended package of care in this rural Mozambican population. Same-day and accelerated ART initiation was feasible and safe in this population including among those with AHD.

Immunomodulatory therapy, risk factors and outcomes of hospital-acquired bloodstream infection in patients with severe COVID-19 pneumonia: a Spanish case-control matched multicentre study (BACTCOVID).

OBJECTIVES: The effect of the use of immunomodulatory drugs on the risk of developing hospital-acquired bloodstream infection (BSI) in patients with COVID-19 has not been specifically assessed. We aim to identify risk factors for, and outcomes of, BSI among hospitalized patients with severe COVID-19 pneumonia. METHODS: We performed a severity matched case-control study (1:1 ratio) nested in a large multicentre prospective cohort of hospitalized adults with COVID-19. Cases with BSI were identified from the cohort database. Controls were matched for age, sex and acute respiratory distress syndrome. A Cox proportional hazard ratio model was performed. RESULTS: Of 2005 patients, 100 (4.98%) presented 142 episodes of BSI, mainly caused by coagulase-negative staphylococci, Enterococcus faecalis and Pseudomonas aeruginosa. Polymicrobial infection accounted for 23 episodes. The median time from admission to the first episode of BSI was 15 days (IQR 9-20), and the most frequent source was catheter-related infection. The characteristics of patients with and without BSI were similar, including the use of tocilizumab, corticosteroids, and combinations. In the multivariate analysis, the use of these immunomodulatory drugs was not associated with an increased risk of BSI. A Cox proportional hazard ratio (HR) model showed that after adjusting for the time factor, BSI was associated with a higher in-hospital mortality risk (HR 2.59; 1.65-4.07; p < 0.001). DISCUSSION: Hospital-acquired BSI in patients with severe COVID-19 pneumonia was uncommon and the use of immunomodulatory drugs was not associated with its development. When adjusting for the time factor, BSI was associated with a higher mortality risk.
