No virological failure in patients living with HIV with past NNRTI resistance-associated mutations switched to doravirine-containing regimens.

Background: Doravirine is licensed in patients living with HIV (PWH) harbouring no prior resistance to any NNRTIs. We aimed to evaluate in real life the efficacy of doravirine with prior NNRTI virological failure and NNRTI resistance-associated mutations (RAMs).

Methods: This observational study included PWH switched to a doravirine-containing regimen between 30 September 2019 and 1 May 2022, with an HIV-1 RNA of ≤50 copies/mL and past NNRTI-RAMs.

Clearance of archived integrase strand transfer inhibitors resistance mutations in people with virologically suppressed HIV infection.

Introduction: We assessed the kinetics of the clearance of integrase strand transfer inhibitors resistance mutations (INSTIs-RMs) and associated factors from people living with HIV (PWH) displaying suppressed viral replication after virological failure (VF) on an INSTI regimen.

Patients And Methods: We included PWH with HIV-RNA viral loads ≤20 copies/mL for at least 5 years in whom INSTIs-RM had been identified at least once in a prior RNA resistance genotyping test. HIV DNAs were sequenced by Sanger sequencing (SS) and ultra-deep sequencing (UDS; detection threshold: 5%) every year over the preceding 5 years.

A case series of intermittent nucleoside analogue-based (NA) regimen to maintain HBV virological suppression in coinfected HBV/HIV patients with suppressed viremia.

Objective: To describe the efficacy of intermittent nucleoside analogue-based (NA) regimen to maintain HBV virological suppression in HBV/HIV-1 patients.

Methods: Conducted between 2014 and 2023, this observational retrospective study included all HBV (positive AgHbs)/HIV-1 coinfected patients with HIV RNA ≤ 50 cp/mL and HBV DNA ≤ 25 UI/mL who were switched to an intermittent (<7/7 days(D)) TDF or TAF-containing antiretroviral (ART) regimen. The primary outcome was the HBV virological success rate (SR) (proportion of patients with HBV pVL < 25 UI/mL) at W48.

Bacterial Genomics for National Antimicrobial Resistance Surveillance in Cambodia.

Background: Antimicrobial resistance (AMR) surveillance in low- and middle-income countries (LMICs) often relies on poorly resourced laboratory processes. Centralized sequencing was combined with cloud-based, open-source bioinformatics solutions for national AMR surveillance in Cambodia.

Methods: Blood cultures growing gram-negative bacteria were collected at six Cambodian hospitals (January 2021 - October 2022).

Case Report: Risk Factors Associated with Mortality in Adults with Burkholderia Pseudomallei Bacteremia: A Retrospective Case Series of Melioidosis in Cambodia.

In resource-scarce settings, melioidosis is associated with up to 80% mortality. Studies of melioidosis in Cambodia report primarily on pediatric populations with localized infection; however, literature describing Cambodian adults with severe melioidosis is lacking. We present a case series of 35 adults with sequence-confirmed Burkholderia pseudomallei bacteremia presenting to a provincial referral hospital in rural Cambodia.

Sexually Transmitted Trichophyton mentagrophytes Genotype VII Infection among Men Who Have Sex with Men.

Transmission of dermatophytes, especially Trichophyton mentagrophytes genotype VII, during sexual intercourse has been recently reported. We report 13 such cases in France. All patients were male; 12 were men who have sex with men.

Doravirine plus lamivudine two-drug regimen as maintenance antiretroviral therapy in people living with HIV: a French observational study.

Background: Two-drug regimens based on integrase strand transfer inhibitors (INSTIs) and boosted PIs have entered recommended ART. However, INSTIs and boosted PIs may not be suitable for all patients. We aimed to report our experience with doravirine/lamivudine as maintenance therapy in people living with HIV (PLWH) followed in French HIV settings.

Intermittent Bictegravir/Emtricitabine/Tenofovir Alafenamide Treatment Maintains High Level of Viral Suppression in Virally Suppressed People Living with HIV.

In this observational study, we aimed to evaluate whether bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) administered 5 or 4 days a week is able to maintain viral suppression in people living with HIV (PLHIV). We enrolled 85 patients who initiated intermittent B/F/TAF between 28 November 2018 and 30 July 2020: median (IQR) age 52 years (46-59), duration of virological suppression 9 years (3-13), CD4 633/mm (461-781). Median follow-up was 101 weeks (82-111).

Anti-inflammatory effects of the prostacyclin analogue iloprost in an in vitro model of inflamed human dental pulp cells.

Iloprost's anti-inflammatory effects on human dental pulp stem cells (HDPCs) are currently unknown. We hypothesized that iloprost could downregulate the expression of inflammatory-related genes and protein in an inflamed HDPC in vitro model. To induce inflammation, the HDPCs were treated with a cocktail of interleukin-1 beta, interferon-gamma, and tumour necrosis alpha, at a ratio of 1:10:100.

Birth Country Influences the Choice of Antiretroviral Therapy in HIV-Infected Individuals: Experience From a French HIV Centre.

Objectives: To assess whether antiretroviral therapy (ART) prescriptions differ between naive and virally suppressed HIV patients born in France (PBFs) and in Sub-Saharan Africa (PBSSAs).

Setting: Observational single-center study.

Methods: We included all PBFs and PBSSAs who entered into care at Pitié-Salpêtrière Hospital, Paris, France, from 01/01/2000 to 31/12/2018, with plasma HIV-RNA>200 copies/mL.

A Case of Perforated Cholecystitis into a Parastomal Hernia.

Introduction: Parastomal hernia is a common complication following an enterostomy. Gallbladder herniation into parastomal hernia is rare and may become symptomatic and inflamed and very rarely can lead to gallbladder perforation. We present the first case of gallbladder perforation inside a parastomal hernia with a unique skin change.

Laparoscopic choledochotomy and choledochoduodenostomy for the management of persistent common bile duct stones.

Choledochotomy and choledochoduodenostomy were commonly used technique in the early twentieth century to extract bile duct stones. Endoscopic retrograde cholangiopancreatography and sphincterotomy revolutionised the scenario and is currently the preferred first-line option for managing choledocholithiasis. However, in certain circumstances, where endoscopic retrograde cholangiopancreatography fails, choledochotomy and choledochoduodenostomy are the only available options.

The Prostacyclin Analog Iloprost Promotes Cementum Formation and Collagen Reattachment of Replanted Molars and Up-regulates Mineralization by Human Periodontal Ligament Cells.

Introduction: This study evaluated the use of the prostacyclin analog iloprost as a root surface treatment agent in promoting acellular cementum (AC) formation and collagen reattachment after tooth replantation in vivo. In addition, its effect on human periodontal ligament cell (hPDLC) mineralization was assessed in vitro.

Methods: First molars of 8-week-old Wistar rats were extracted.

Long COVID-19 symptoms: Clinical characteristics and recovery rate among non-severe outpatients over a six-month follow-up.

Background: To describe persistent symptoms in long COVID-19 non-severe outpatients and report the 6-month clinical recovery (CR) rate.

Methods: Observational study enrolling outpatients (≥ 18 years) with confirmed non-severe COVID-19 (positive nasopharyngeal RT-PCR or presence of SARS-CoV-2 antibodies) who consulted for persistent symptoms after the first pandemic wave (March-May 2020). CR was assessed at the 6-month visit and defined as complete (no symptom), partial (persistent symptoms of lower intensity) or lack of recovery (no improvement).

Household transmission of SARS-CoV-2 infection in the Paris/Ile-de-France area.

This st udy aims to evaluate the prevalence of SARS-CoV-2 antibodies in locked-down family households to determine viral dynamics and immunity acquisition. COVID-19 individuals and their households in lockdown under the same roof during early spring 2020 were interviewed and tested using rapid immunochromatographic lateral flow antibodies assays (LFA) between July and September 2020. Outcomes were secondary infection rate (SIR) among contacts, household infection rate, and predictors of transmission.

Prevalence and factors associated with symptom persistence: A prospective study of 429 mild COVID-19 outpatients.

Introduction: Persistent symptoms have recently emerged as a clinical issue in COVID-19. We aimed to assess the prevalence and risk factors in symptomatic non-hospitalized individuals with mild COVID-19.

Methods: We performed a prospective cohort study of symptomatic COVID-19 outpatients, from March to May 2020, with weekly phone calls from clinical onset until day 30 and up to day 60 in case of persistent symptoms.

Kinetics of Archived M184V Mutation in Treatment-Experienced Virally Suppressed HIV-Infected Patients.

Background: We aimed to assess the kinetics of drug-resistant viral variants (DRVs) harboring the M184V mutation in proviral DNA of long-term virally suppressed patients, and factors associated with DRV persistence.

Methods: Human immunodeficiency virus (HIV) DNA from blood cells stored in 2016 and 2019 was sequenced using Sanger and ultradeep sequencing (SS and UDS; detection threshold 1%) in antiretroviral therapy (ART)-treated patients with HIV RNA < 50 copies/mL for at least 5 years, with past M184V mutation documented in HIV RNA.

Results: Among 79 patients, by combining SS and UDS, M184V was found to be absent in 26/79 (33%) patients and persistent in 53/79 (67%).
