Immune Response to an Adjuvanted Recombinant Zoster Vaccine in Japanese Patients with Rheumatoid Arthritis Receiving Upadacitinib (End Zoster-J Study): Study Protocol for an Exploratory Parallel Triple-Arm Prospective Trial.

: Janus kinase (JAK) inhibitors have emerged as a new class of disease-modifying anti-rheumatic drugs in the treatment of rheumatoid arthritis (RA). However, herpes zoster is one of the common adverse events of JAK inhibitors, including upadacitinib, which is especially high in Japanese patients with RA compared to those from Western countries. Recombinant zoster vaccine (Shingrix) is an adjuvanted subunit vaccine containing varicella-zoster virus (VZV) glycoprotein E (gE) that is effective in adults over 50 years of age.

Effects of smoking cessation on endothelial function as assessed by flow-mediated total dilation.

Background: In assessing the effects of smoking cessation on endothelial function, low-flow-mediated constriction (L-FMC) may provide complementary information to flow-mediated dilation (FMD). However, the value of flow-mediated total dilation (FMTD), an index that incorporates L-FMC into FMD, remains underreported. We aimed to evaluate the effect of smoking cessation on endothelial function, as assessed by FMD and FMTD, and clarify its associated clinical factors.

Exploring the Link between Varicella-Zoster Virus, Autoimmune Diseases, and the Role of Recombinant Zoster Vaccine.

The varicella-zoster virus (VZV) is a human neurotropic herpes virus responsible for varicella and herpes zoster (HZ). Following primary infection in childhood, VZV manifests as varicella (chickenpox) and enters a period of latency within the dorsal root ganglion. A compromised cellular immune response due to aging or immunosuppression triggers viral reactivation and the development of HZ (shingles).

Predictive factors and treatment outcomes associated with difficult-to-treat rheumatoid arthritis conditions: the ANSWER cohort study.

Objectives: To investigate the predictive factors for difficult-to-treat rheumatoid arthritis (D2T RA) and assess the efficacy of biologic DMARDs (bDMARDs) and Janus kinase inhibitors (JAKi).

Methods: Retrospective analysis was conducted on data from the ANSWER cohort comprising 3623 RA patients treated with bDMARDs or JAKi in Japan. Multivariate Cox proportional hazards modelling was used to analyse the hazard ratios (HRs) for treatment retention.

Effects of ipragliflozin on left ventricular diastolic function in patients with type 2 diabetes: A sub-analysis of the PROTECT trial.

Background: We hypothesized that the beneficial effects of sodium-glucose cotransporter-2 (SGLT2) inhibitors on diastolic function might depend on baseline left ventricular (LV) systolic function.

Methods: To investigate the effects of SGLT2 inhibitors on LV diastolic function in patients with type 2 diabetes mellitus (T2DM), we conducted a post-hoc sub-study of the PROTECT trial, stratifying the data according to LV ejection fraction (LVEF) at baseline. After excluding patients without echocardiographic data at baseline or 24 months into the PROTECT trial, 31 and 38 patients with T2DM from the full analysis dataset of the PROTECT trial who received ipragliflozin or no SGLT2 inhibitor (control), respectively, were included.

Lymphoproliferative disorder progressing after partial remission following immunosuppressive drugs withdrawal in a patient with rheumatoid arthritis.

Lymphoproliferative disorders (LPDs) are serious complications that arise in patients with rheumatoid arthritis (RA) receiving immunosuppressive drugs (ISDs). Here, we reported a 73-year-old woman diagnosed with RA at 60 years of age and treated with methotrexate, bucillamine, prednisolone, and infliximab. She was referred to our hospital, Osaka Metropolitan University Hospital, with general malaise, pancytopenia, a right adrenal mass, and enlarged periaortic lymph nodes.

Lack of impact of ipragliflozin on endothelial function in patients with type 2 diabetes: sub-analysis of the PROTECT study.

Background: We assessed the impact of 24 months of treatment with ipragliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on endothelial function in patients with type 2 diabetes as a sub-analysis of the PROTECT study.

Methods: In the PROTECT study, patients were randomized to receive either standard antihyperglycemic treatment (control group, n = 241 ) or add-on ipragliflozin treatment (ipragliflozin group, n = 241) in a 1:1 ratio. Among the 482 patients in the PROTECT study, flow-mediated vasodilation (FMD) was assessed in 32 patients in the control group and 26 patients in the ipragliflozin group before and after 24 months of treatment.

Rheumatic Immune-Related Adverse Events due to Immune Checkpoint Inhibitors-A 2023 Update.

With the aging of the population, malignancies are becoming common complications in patients with rheumatoid arthritis (RA), particularly in elderly patients. Such malignancies often interfere with RA treatment. Among several therapeutic agents, immune checkpoint inhibitors (ICIs) which antagonize immunological brakes on T lymphocytes have emerged as a promising treatment option for a variety of malignancies.

Difficult-to-treat rheumatoid arthritis: Current concept and unsolved problems.

Over the past several decades, the treatment of rheumatoid arthritis (RA) has advanced significantly, and clinical, structural, and functional remission are achievable therapeutic goals. However, a substantial number of patients show resistance to multiple drugs. In particular, patients whose disease activity cannot be controlled despite the use of two or more biological disease-modifying antirheumatic drugs (DMARDs) or targeted synthetic DMARDs (tsDMARDs) with different mechanisms of action (MOA) have recently been referred to as having difficult-to-treat RA (D2T RA).

Predictors of endothelial function improvement in patients with mild hypertriglyceridemia without evidence of coronary artery disease treated with purified eicosapentaenoic acid.

Background And Aims: Eicosapentaenoic acid (EPA) has been reported to reduce cardiovascular risk in patients with hypertriglyceridemia. Although several mechanisms underlying the effects of EPA have been demonstrated, those responsible for its beneficial role in patients with hypertriglyceridemia without evidence of coronary artery disease (CAD) have not been fully elucidated. We sought to clarify the main factors associated with EPA administration that led to improved endothelial function.

Predictors of the effects of smoking cessation on the endothelial function of conduit and digital vessels.

Smoking predisposes individuals to endothelial dysfunction. Flow-mediated dilation (FMD) and reactive hyperemia peripheral artery tonometry (RH-PAT) are used to assess endothelial function. However, whether smoking cessation demonstrates comparable effects on endothelial function evaluated by FMD and RH-PAT remains unclear.

The 1-min animal test as a mental status screening examination in patients with diabetes.

Background: Detecting and treating dementia at an early stage are important. Although the Revised Hasegawa Dementia Scale (HDS-R) is commonly used to detect dementia, it takes about 10 min to complete. In contrast, the 1-min animal test (OMAT) takes only 1 min to complete and may be a helpful screening test for general practitioners in deciding whether to proceed with administering further diagnostic tests such as the HDS-R.

Favorable effects of motivational interviewing and support in a patient with schizophrenia and alcohol abuse.

A 42-year-old man with schizophrenia was referred to our hospital after 2 weeks of worsening fatigue. His hemoglobin level was 2.8 g/dL owing to folic acid deficiency stemming from alcohol abuse and consumption of unbalanced meals.

Addison's Disease Caused by Tuberculosis with Atypical Hyperpigmentation and Active Pulmonary Tuberculosis.

We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis.
