Factors associated with incomplete adherence to integrase strand transfer inhibitor-containing single-tablet regimen among Japanese people living with HIV.

Background: People living with human immunodeficiency virus (PLWH) require high rates of medication adherence to antiretroviral therapy (ART) for a successful treatment outcome. Understanding the factors associated with incomplete adherence among those receiving integrase strand transfer inhibitor-containing single-tablet regimens (INSTI-STRs) is crucial for improving treatment outcomes. This study aimed to identify the factors contributing to incomplete ART adherence among Japanese PLWH receiving INSTI-STRs.

Factors associated with patient satisfaction with antiretroviral therapy in Japan: A cross-sectional, multicenter study.

Background: Current antiretroviral therapy (ART) regimens are highly effective; therefore, to differentiate between various regimens, considering patient-reported outcomes is essential. This study aimed to assess patient satisfaction with their current ART regimens and investigate factors associated with the Human Immunodeficiency Virus Treatment Satisfaction Questionnaire: Status (HIVTSQs) score.

Methods: This cross-sectional, multicenter study was conducted in Japan between April and December 2021.

Changes in Leptin to Adiponectin Ratio After Antiretroviral Therapy: A Pilot Observational Study.

Aim: Weight gain with the use of dolutegravir, bictegravir, and tenofovir alafenamide for antiretroviral therapy has been reported. However, studies on changes in body composition and the leptin/adiponectin ratio after antiretroviral therapy initiation are limited. These factors are important because they can be used as indicators of metabolic syndrome and cardiovascular disease risk.

Comparison between the impact of tenofovir alafenamide and that of abacavir on rapid kidney function decline: A retrospective observational study.

Objectives: To compare the impact of tenofovir alafenamide (TAF) on the slope of the estimated glomerular filtration rate (eGFR) with that of abacavir in Japanese patients living with HIV infection.

Methods: The participants in this single-centre, retrospective, observational study were Japanese patients with HIV infection who started antiretroviral therapy with TAF/emtricitabine or abacavir/lamivudine or were switched from tenofovir disoproxil fumarate/emtricitabine to TAF/emtricitabine or abacavir/lamivudine (anchor drugs remained constant) between January 2012 and December 2020. The eGFR slope was defined as the regression coefficient between eGFR and time.

Effect of switching from tenofovir disoproxil fumarate to tenofovir alafenamide on estimated glomerular filtration rate slope in patients with HIV: A retrospective observational study.

Introduction: There is limited data on the effects of switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) on estimated glomerular filtration rates (eGFR) slope in patients with human immunodeficiency virus (HIV) infection. This study aimed to compare the eGFR slope when administering TDF and TAF and to investigate the predictors of improvement in eGFR slope after switching from TDF to TAF.

Methods: We conducted a single-center, retrospective, observational study in Japanese patients with HIV infection who switched the antiretroviral drug from TDF to TAF.

Decrease in voriconazole concentration-to-dose ratio after letermovir initiation: a retrospective, observational study.

Letermovir is used to prevent cytomegalovirus infection in hematopoietic stem cell transplantation (HSCT) recipients. Although this agent decreases voriconazole exposure in healthy individuals, the effect of coadministration of letermovir and voriconazole in HSCT recipients is unknown. This retrospective, observational, single-center study was conducted between January 2016 and July 2019 to examine the voriconazole concentration-to-dose ratio over three periods: (A) (days -7 to -1 [day 0: day of HCST]), (B) (days 4-10), and (C) (days 11-17).

Tacrolimus Concentration after Letermovir Initiation in Hematopoietic Stem Cell Transplantation Recipients Receiving Voriconazole: A Retrospective, Observational Study.

Letermovir (LMV) is a new antiviral drug used to prevent cytomegalovirus infection in hematopoietic stem cell transplantation (HSCT) recipients. It has been reported to increase tacrolimus (TAC) exposure and decrease voriconazole (VRCZ) exposure in healthy participants. However, VRCZ inhibits the metabolism of TAC.

Basic survey for the prevention of intraoral residual medication in older adults: A pilot study.

Objective: This study aimed to assess the relationship between oral hygiene/stomatognathic function and residual intraoral medication in older adults and to identify the oral factors associated with residual oral medication.

Methods: The study included 309 older adults (77 men, 232 women, mean age: 74.1 ± 7.

Utility of urinary liver-type fatty acid-binding protein as a predictor of renal dysfunction in Japanese patients with HIV receiving tenofovir disoproxil fumarate with low urinary β2 microglobulin levels: a retrospective observational study.

Background: Tenofovir disoproxil fumarate (TDF) is known to reduce estimated glomerular filtration rate (eGFR). It is clinically important to identify patients at high risk for renal dysfunction as early as possible. Among the tubular markers, urinary β2 microglobulin (Uβ2MG) is a well-known biomarker of TDF-related tubulopathy.

Urinary liver-type fatty acid-binding protein levels as a potential risk factor for renal dysfunction in male HIV-infected Japanese patients receiving antiretroviral therapy: a pilot study.

Renal dysfunction is recognized with increasing frequency among the non-infectious co-morbidities associated with human immunodeficiency virus (HIV) infection. Recently, urinary liver-type fatty acid-binding protein (L-FABP) was suggested to be a predictor of the progression of renal dysfunction in patients without HIV. However, little is known regarding the utility of urinary L-FABP as a predictor of renal dysfunction in patients with HIV.

New paste for severe stomatitis in patients undergoing head-and-neck cancer radiotherapy and/or chemotherapy with oral appliance.

Background: The aim of the present study was to evaluate the physical properties of "admixture paste", which is a commercially available gel containing hinokitiol for use against severe stomatitis, and its characteristics as a moisturizing gel and denture adhesive.

Methods: The admixture paste, which contained dexamethasone (Dexaltin®), gel for oral care (Refrecare H®) and petrolatum, and its 3 components, either alone or in different combinations, were subjected to viscosity, adhesiveness and elution testing to compare their physical properties. Viscosity was measured with a stress-controlled rheometer.

A potential drug interaction between phenobarbital and dolutegravir: A case report.

In this report, we describe a human immunodeficiency virus (HIV)-infected patient in whom changes in phenobarbital (PB) dosage resulted in associated changes in plasma concentrations of dolutegravir (DTG). His plasma concentrations of DTG were 0.934, 0.

Quality of life of people living with HIV compared with that of the general population in Japan.

Objective: To evaluate the health-related quality of life (HRQOL) of people living with HIV (PLWH) in Japan.

Methods: A cross-sectional comparative study was conducted between June and December 2016 on PLWH. HRQOL was assessed using the Japanese version of the Short Form-36 Health Survey questionnaire (SF-36), and the three-component model of SF-36 scores was used.

The association between urinary liver-type fatty acid-binding protein and chronic kidney disease classification in HIV-infected Japanese patients.

Background: Renal dysfunction is recognized with increasing frequency among the noninfectious comorbidities associated with human immunodeficiency virus (HIV) infection. Urinary liver-type fatty acid-binding protein (L-FABP) has been shown to be a new biomarker to screen for not only tubulointerstitial damage but also kidney dysfunction.

Methods: We performed a cross-sectional study to determine the association between the urinary L-FABP and chronic kidney disease (CKD) among 77 HIV-infected Japanese patients by backward-stepwise multivariable logistic regression.
