Anecdotal evidence rapidly accumulated during March 2020 from sites around the world that sudden hyposmia and hypogeusia are significant symptoms associated with the SARS-CoV-2 pandemic. Our ...objective was to describe the prevalence of hyposmia and hypogeusia and compare it in hospitalized and non-hospitalized COVID-19 patients to evaluate an association of these symptoms with disease severity. We performed a cross-sectional survey during 5 consecutive days in March 2020, within a tertiary referral center, associated outpatient clinic, and two primary care outpatient facilities in Paris. All SARS-CoV-2-positive patients hospitalized during the study period and able to be interviewed (
n
= 198), hospital outpatients seen during the previous month (
n
= 129), and all COVID-19-highly suspect patients in two primary health centers (
n
= 63) were included. Hospitalized patients were significantly more often male (64 vs 40%) and older (66 vs 43 years old in median) and had significantly more comorbidities than outpatients. Hyposmia and hypogeusia were reported by 33% of patients and occurred significantly less frequently in hospitalized patients (12% and 13%, respectively) than in the health centers’ outpatients (33% and 43%, respectively) and in the hospital outpatients (65% and 60%, respectively). Hyposmia and hypogeusia appeared more frequently after other COVID-19 symptoms. Patients with hyposmia and/or hypogeusia were significantly younger and had significantly less respiratory severity criteria than patients without these symptoms. Olfactory and gustatory dysfunction occurs frequently in COVID-19, especially in young, non-severe patients. These symptoms might be a useful tool for initial diagnostic work-up in patients with suspected COVID-19.
Abstract
Background
The incidence of sexually transmitted infections (STI) is increasing in Western countries whilst travel plays a major role in STI dissemination worldwide. However, there is no ...study distinguishing HIV-positive and HIV-negative travellers.
Methods
We retrospectively evaluated the epidemiological, clinical and biological characteristics of the patients diagnosed with a travel-related STI between 2008 and 2016. We describe and compare the spectrum of STI diagnosed amongst HIV-positive and negative travellers.
Methods
Overall, 163 travel-related STI were identified in 140 patients (89% male, 54% men having sex with men, 40% HIV-positive). Symptoms occurred during travel in 39% of them, otherwise the median time between return and symptoms’ onset was 13 days. Amongst the 84 HIV-negative travellers, the main STI were primary HIV infections (n = 36, 38%), Neisseria gonorrhoeae (NG) infections (17%) and primary herpes infection (14, vs 1.5% amongst HIV-positive travellers, P = 0.01). The regions of exposure to HIV were concordant with the known geographical distribution of HIV subtypes. Amongst the 56 HIV-positive travellers, the main STI were syphilis (43, vs 6% amongst HIV-negative travellers, P = 0.01), Chlamydia trachomatis (CT) infections (22, vs 13% amongst HIV-negative travellers, P = 0.08), NG infections (13%) and acute hepatitis C (12, vs 1% amongst HIV-negative travellers, P = 0.01), with a predominance of anal forms for both CT and NG infections.
Conclusions
The spectrum of STI diagnosed in returning travellers is broad with important differences according to HIV status. In our setting, primary HIV infection was the leading STI in non-HIV infected patients, which suggests that pre-exposure prophylaxis may have a role in HIV prevention in at-risk travellers.
Bedaquiline is recommended by the World Health Organization for the treatment of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB). We pooled data from 5 cohorts of ...patients treated with bedaquiline in France, Georgia, Armenia, and South Africa and in a multicountry study. The rate of culture conversion to negative at 6 months (by the end of 6 months of treatment) was 78% (95% CI 73.5%-81.9%), and the treatment success rate was 65.8% (95% CI 59.9%-71.3%). Death rate was 11.7% (95% CI 7.0%-19.1%). Up to 91.1% (95% CI 82.2%-95.8%) of the patients experienced >1 adverse event, and 11.2% (95% CI 5.0%-23.2%) experienced a serious adverse event. Lung cavitations were consistently associated with unfavorable outcomes. The use of bedaquiline in MDR and XDR TB treatment regimens appears to be effective and safe across different settings, although the certainty of evidence was assessed as very low.
Bedaquiline, a recently approved drug for the treatment of multidrug-resistant tuberculosis (MDR-TB), is recommended for a duration of 24 weeks. There are scarce data on patients treated with this ...drug outside clinical trials.All MDR-TB patients who started treatment from January 1, 2011 to December 31, 2013 and received ≥30 days of bedaquiline were included in a multicentre observational cohort.Among 45 MDR-TB patients, 53% harboured isolates resistant to both fluoroquinolones and second-line injectables, and 38% harboured isolates resistant to one of these drug classes. Median bedaquiline treatment duration was 361 days and 33 patients (73%) received prolonged (>190 days) bedaquiline treatment. Overall, 36 patients (80%) had favourable outcome, five were lost to follow-up, three died, and one failed and acquired bedaquiline resistance. No cases of recurrence were reported. Severe and serious adverse events were recorded in 60% and 18% of patients, respectively. Values of Fridericia-corrected QT interval (QTcF) >500 ms were recorded in 11% of patients, but neither arrhythmias nor symptomatic cardiac side-effects occurred. Bedaquiline was discontinued in three patients following QTcF prolongation. No significant differences in outcomes or adverse events rates were observed between patients receiving standard and prolonged bedaquiline treatment.Bedaquiline-containing regimens achieved favourable outcomes in a large proportion of patients. Prolonged bedaquiline treatment was overall well tolerated in this cohort.
•Positive direct antiglobulin tests (DAT) have been reported in cases of post-artesunate delayed hemolysis (PADH) during severe malaria.•Patients with DAT positivity were not associated with ...PADH.•DAT does not appear to be a marker of PADH.•Overall, outcomes were favorable without corticosteroids, even in cases of PADH.
Objectives: Positive direct antiglobulin tests (DATs) have been reported in cases of post-artesunate delayed hemolysis (PADH), but the causal role of auto-immune hemolysis remains unclear. We aimed to analyze a cohort of patients with PADH and DAT during severe malaria.
Methods: We describe PADH and DAT results in a 7-year multi-center retrospective cohort of patients receiving artesunate for severe imported malaria.
Results: Of 337 patients treated with artesunate, 46 (13.6%) had at least one DAT result within 30 days of treatment initiation, and 25/46 (54.3%) had at least one positive DAT. Among 40 patients with available data, 17 (42.5%) experienced PADH. Patient characteristics were similar for patients with a positive or negative DAT, and DAT positivity was not associated with PADH occurrence (P = 0.36). Among patients, 5/13 (38.5%) with a positive DAT after day 7 experienced PADH, compared to 10/13 (76.9%) of those with a negative DAT after day 7 (P = 0.11). Overall, 41% of patients required blood transfusions, and outcome was favorable without corticosteroids, even in cases of PADH.
Conclusions: DAT does not appear to be a marker of PADH, but rather an indirect marker of an immune-mediated mechanism. DAT positivity should not lead to the administration of systemic corticosteroids during PADH.
Travellers are at risk of STIs. The relationship between travel and STIs is obvious, as evidenced by the histories of syphilis, HIV infection and more recently, Mpox. STIs continue to emerge. ...Antimicrobial resistance is a huge concern. Thus, the importance of safer sex and condom use should be re-emphasized.
Cutaneous larva migrans caused by the larvae of animal hookworms is the most frequent skin disease among travelers returning from tropical countries. Complications (impetigo and allergic reactions), ...together with the intense pruritus and the significant duration of the disease, make treatment mandatory. Freezing the leading edge of the skin track rarely works. Topical treatment of the affected area with 10%-15% thiabendazole solution or ointment has limited value for multiple lesions and hookworm folliculitis, and requires applications 3 times a day for at least 15 days. Oral thiabendazole is poorly effective when given as a single dose (cure rate, 68%-84%) and is less well tolerated than either albendazole or ivermectin. Treatment with a single 400-mg oral dose of albendazole gives cure rates of 46%-100%; a single 12-mg oral dose of ivermectin gives cure rates of 81%-100%.
A woman with extremely drug-resistant tuberculosis treated with a drug regimen including linezolid and bedaquiline during her last 3 weeks of pregnancy gave birth to a child without abnormalities. No ...fetal toxicities were noted by 2 years after delivery. This drug combination might be safe during the late third trimester of pregnancy.
