Dolutegravir Resistance in African Programmatic Settings Among Patients With Failure of Dolutegravir-based ART.

Dolutegravir resistance is emerging in routine clinical contexts in southern Africa, primarily in patients with prior treatment experience failing dolutegravir-based antiretroviral therapy (ART). This potential issue was raised by The Nucleosides and Darunavir/Dolutegravir in Africa trial that compared dolutegravir and boosted protease inhibitor-based therapy as second-line ART, in which new dolutegravir resistance was observed at failure. However, recent data suggest that also at risk are patients who were transitioned to dolutegravir from non-nucleoside reverse transcriptase inhibitor-based ART while viremic.

Early trajectories of virological and immunological biomarkers and clinical outcomes in patients admitted to hospital for COVID-19: an international, prospective cohort study.

Background: Serial measurement of virological and immunological biomarkers in patients admitted to hospital with COVID-19 can give valuable insight into the pathogenic roles of viral replication and immune dysregulation. We aimed to characterise biomarker trajectories and their associations with clinical outcomes.

Methods: In this international, prospective cohort study, patients admitted to hospital with COVID-19 and enrolled in the Therapeutics for Inpatients with COVID-19 platform trial within the Accelerating COVID-19 Therapeutic Interventions and Vaccines programme between Aug 5, 2020 and Sept 30, 2021 were included.

Effect of Neutralizing Monoclonal Antibody Treatment on Early Trajectories of Virologic and Immunologic Biomarkers in Patients Hospitalized With COVID-19.

Background: Neutralizing monoclonal antibodies (nmAbs) failed to show clear benefit for hospitalized patients with coronavirus disease 2019 (COVID-19). Dynamics of virologic and immunologic biomarkers remain poorly understood.

Methods: Participants enrolled in the Therapeutics for Inpatients with COVID-19 trials were randomized to nmAb versus placebo.

Clinical and Demographic Factors Associated With COVID-19, Severe COVID-19, and SARS-CoV-2 Infection in Adults: A Secondary Cross-Protocol Analysis of 4 Randomized Clinical Trials.

Importance: Current data identifying COVID-19 risk factors lack standardized outcomes and insufficiently control for confounders.

Objective: To identify risk factors associated with COVID-19, severe COVID-19, and SARS-CoV-2 infection.

Design, Setting, And Participants: This secondary cross-protocol analysis included 4 multicenter, international, randomized, blinded, placebo-controlled, COVID-19 vaccine efficacy trials with harmonized protocols established by the COVID-19 Prevention Network.

Burden of Hyperglycemia in Patients Receiving Corticosteroids for Severe COVID-19.

Although corticosteroid therapy is the standard of care for all patients hospitalized with severe coronavirus disease 2019 (COVID-19), the studies demonstrating the mortality-benefit ratio of corticosteroids were limited to fully evaluate their adverse effects. To determine the severity of corticosteroid-induced hyperglycemia in patients with and without diabetes mellitus, we retrospectively collected data from the medical records of patients hospitalized with COVID-19 before and after corticosteroids were the standard of care. Corticosteroid-induced hyperglycemia was more severe in patients hospitalized with COVID-19 with diabetes than those without diabetes.

Efficacy and Safety of Ensovibep for Adults Hospitalized With COVID-19 : A Randomized Controlled Trial.

Background: Ensovibep (MP0420) is a designed ankyrin repeat protein, a novel class of engineered proteins, under investigation as a treatment of SARS-CoV-2 infection.

Objective: To investigate if ensovibep, in addition to remdesivir and other standard care, improves clinical outcomes among patients hospitalized with COVID-19 compared with standard care alone.

Design: Double-blind, randomized, placebo-controlled, clinical trial.

Staphylococcal Skin and Soft Tissue Infections.

Staphylococcus aureus is the most common bacteria causing purulent skin and soft tissue infections. Many disease-causing S aureus strains are methicillin resistant; thus, empiric therapy should be given to cover methicillin-resistant S aureus. Bacterial wound cultures are important for characterizing local susceptibility patterns.

Oral fosfomycin use for pyelonephritis and complicated urinary tract infections: a 1 year review of outcomes and prescribing habits in a large municipal healthcare system.

Background: The rising incidence of MDR uropathogens has driven increased use of oral fosfomycin for treatment of complicated urinary tract infections (cUTIs). However, there are limited data to support its use for cUTI, especially pyelonephritis.

Methods: We performed a retrospective review of all oral fosfomycin prescriptions between 1 January and 31 December 2017 in the Los Angeles County Department of Health Service system, the second largest US municipal health system.

endocarditis diagnosed by fungemia plus serum antigen testing.

Fungal endocarditis remains an uncommon clinical diagnosis, though is likely to become more frequent due to the global increase in transplantations and cardiac valvular surgery. A case of prosthetic valve endocarditis due to Aspergillus fumigatus is described that was diagnosed with serologic fungal markers and confirmed with positive blood cultures, an uncommon finding.

High-Dose Fluconazole Consolidation Therapy for Cryptococcal Meningitis in Sub-Saharan Africa: Much to Gain, Little to Lose.

Cryptococcal meningitis accounts for an estimated 25% of AIDS-associated mortality in sub-Saharan Africa. Accumulating animal and human evidence suggest that a higher, more fungicidal, dose of fluconazole during consolidation therapy could be more effective in controlling residual infection and may help significantly reduce posthospitalization mortality. Although the potential for toxicity is low, the use of fluconazole at a dose of 800 mg/day during consolidation therapy requires examination in a randomized clinical trial.

Nonprogrammable and programmable cerebrospinal fluid shunt valves: a 5-year study.

Object: Programmable valves (PVs) for shunting CSF have increasingly replaced nonprogrammable valves (NPVs). There have been only a few longer-term studies (≥ 5 years) conducted that have compared the effectiveness of NPVs with that of PVs for children with hydrocephalus, and only 1 study has reported NPVs as being favorable over PVs. The objective of this retrospective study was to compare the long-term survival of these 2 types of shunt valves.
