Despite proven efficacy of maintenance pharmacotherapy in schizophrenia, indefinite neuroleptic treatment may not be optimal for all patients. It is uncertain how long maintenance therapy should be continued and how to identify those patients who can withdraw eventually from neuroleptics. Prospective randomized con-trolled studies are the ideal approach for evaluation of medication, however they are inevitably for the short term and may not be suitable for addressing the above-mentioned issue. In this study, we naturalistically followed up 30 remitted schizophrenics for 10.7 years on average and examined factors that might affect the outcomes. Of 30 remitted patients, 8 cases (26.7%) ceased neuroleptic use completely for more than 2 years. The details of clinical courses of those 8 cases were described as case reports in this report. Importantly, 4 of 8 withdrawal cases required 2 or more trials' in order for neuroleptic withdrawal to reach a drug-free state. Factors which significantly affected successful withdrawal involved the mode of onset and the ages at first neuroleptic withdrawal trial. Our results suggest that approximately one-fourth of completely remitted patients could withdraw neuroleptics, but certain cases may need withdrawal trials at least a few times to accomplish the drug-free state.

We examined satisfaction and perceived challenges with antiretroviral therapy (ART) among people living with HIV (PLHIV) in Japan vs three other Asian countries (China, Taiwan, South Korea), and 21 non-Asian countries, using data from the 2019 Positive Perspectives Study (pooled sample size from all 25 countries = 2389). Participants in other Asian countries were more likely than those in Japan to report they missed ART ≥ 1 time in the past month because they were depressed/overwhelmed (57.4%[89/155] vs 32.0%[24/75]), had privacy concerns (56.8%[88/155] vs 30.7%[23/75]), were concerned about the potential long-term negative impacts of ART (46.5%[72/155] vs 26.7%[20/75]), or just wanted to forget about HIV (45.8%[71/155] vs 22.7%[17/75]). ART satisfaction however did not differ significantly between surveyed PLHIV in Japan (54.7%[41/75]) vs those in other Asian countries (47.7%[74/155]). The percentage who felt that daily ART dosing limited their lives was 36.0%[27/75] among participants from Japan, 48.4%[75/155] among participants from other Asian countries, and 27.3%[589/2159] among those from non-Asian countries. Within a structural equation model using pooled data from all 25 countries, positive correlations were seen between ART satisfaction and "provider engagement" (β = 0.35), high perceived control over ART dosing schedule (β = 0.28), and the belief that ART prevents HIV transmission (β = 0.16). Conversely, negative correlations were seen between ART satisfaction and experience of ART side-effects (β = - 0.24), high "ART anxiety" (β = - 0.20); and being on multi-tablet regimens (β = - 0.13). Those ART-satisfied reported higher self-rated health and greater ART adherence. These findings underscore the need for patient-centered care to enhance treatment satisfaction and improve ART adherence., (© 2021. The Author(s).)

Introduction: Dolutegravir (DTG), a novel HIV-integrase strand transfer inhibitor (INSTI), is usually used with multiple antiretrovirals (ARVs) for treatment of HIV. DTG is now approved as Tivicay tablets in over 120 countries and Triumeq combination tablets (DTG/abacavir [ABC]/lamivudine [3TC]) in over 90 countries. In Japan, these formulations have been marketed since 2014 and 2015. The post-marketing prospective surveillance has been conducted as part of the HIV-Related Drug (HRD) cooperative survey aimed to collect actual drug use information in all of these DTG-treated patients in accordance with conditions for initial approvals., Methods: The survey has been conducted to evaluate long-term safety and effectiveness of DTG since 2014, for approximately 6 years. The safety was evaluated by incidence of adverse drug reactions (ADRs) and change in body weight. The effectiveness was evaluated by plasma HIV RNA copies/mL and peripheral CD4 + cell counts., Results: Of 2292 patients in 30 Japanese sites, 565 (24.65%) reported ADRs. The most common ADR was blood creatinine increased (4.28%). Incidence of ADRs was statistically significantly higher in patients with severe symptoms (Centers for Disease Control and Prevention [CDC] categories B and C) than those with category A, and in patients with comorbidities than those without comorbidities. Whereas incidence of ADRs was statistically significantly lower in antiretroviral therapy (ART)-experienced patients than that in ART-naïve patients. Incidence of ADRs related to suicide or self-injurious behavior was statistically significantly higher in patients with comorbidities of psychiatric disorders than those without comorbidities. The body weight tended to increase over time and those changes and percentage changes from baseline were greater in ART-naïve patients compared with ART-experienced patients. HIV RNA copies/mL and CD4 + cell counts showed favorable shifts from baseline in both ART-naïve and ART-experienced patients., Conclusion: The results of the survey identified no new safety and effectiveness risks in Japanese patients with HIV/AIDS treated with DTG., (© 2021.

Background: Previous studies have reported a significant increase in age-related magnetic resonance imaging (MRI) changes in relatively younger people living with HIV (PLWH). However, there is little data available for brain changes in Asian PLWH. The data to differentiate HIV specific brain change from usual aging change was also sparse. To clarify them, we assessed the presence of leukoaraiosis and brain atrophic changes on MRI in young and middle-aged Japanese PLWH., Methods: We reviewed data from well-controlled PLWH (age: 20-64 years) and coeval controls. We evaluated the presence of leukoaraiosis, as well as the extent of whole-brain grey matter (GM) atrophy and parahippocampal atrophy on brain MRI and determined between-group differences. Moreover, we evaluated the severity of parahippocampal atrophy based on the voxel-based specific regional analysis system for Alzheimer's disease., Results: We enrolled 40 PLWH and 33 controls (median age: 40.15 and 48.00 years, respectively, [ p  = .3585]). Leukoaraiosis was significantly more prevalent among the PLWH (20 cases [50%]) than in the controls (9 cases [27.3%]) (univariate: p  = .0483, multivariate: p  = .0206). The extent of whole-brain GM atrophy was significantly greater in the PLWH than in the controls (univariate: p  < .001, multivariate: p  = .0012). Contrastingly, there was no significant between-group difference in the extent and severity of parahippocampal atrophy., Conclusions: Aging changes in the brain were significantly more prevalent in well-controlled Japanese PLWH. However, the process of atrophic brain changes might differ between HIV and one of age-related diseases, Alzheimer's disease.

Objective: Fosamprenavir, a protease inhibitor (PI) to treat human immunodeficiency virus (HIV)-infected patients, has been approved in more than 40 countries and mainly used with nucleoside reverse transcriptase inhibitors. In Japan, Lexiva tablet (fosamprenavir calcium hydrate) has been marketed since January 2005 and used in clinical practice. The safety and effectiveness of fosamprenavir in HIV-infected Japanese patients were evaluated in an observational surveillance study (OTH112334). Methods: A post-marketing surveillance study (PMS) of fosamprenavir usage in HIV-infected Japanese subjects evaluating drug safety was conducted under Good Post-marketing Study Practice from January 2005 to December 2014. Results: Of 364 patients receiving fosamprenavir, 51% received emtricitabine/tenofovir disoproxil fumarate. Adverse events whose causal relationship could not be completely ruled out (adverse drug reactions; ADRs) were reported in 43.7%; the most common were diarrhoea (10.4%), hyperlipidaemia (8.5%) and hypertriglyceridaemia (6.9%). Serious ADRs were reported in 26 patients (32 events), including 1 death attributed to hepatic failure. Most ADRs occurred within 180 days after fosamprenavir was started. ADRs were more frequent in patients with the Centers for Disease Control and Prevention category B (AIDS or lipid disorders) or in those taking fosamprenavir combined with abacavir and lamivudine. Although spontaneous bleeding has been reported in hemophiliac patients taking other PIs, in this survey, only one muscle haemorrhage case was reported in 24 hemophiliac patients. Conclusions: The results of this PMS analysis in Japan support its known safety profile and identified no new safety risks for people living with HIV/AIDS in Japan currently on, or beginning treatment with, fosamprenavir.

Purpose: Neurocognitive disorder has been noted as a long-term complication in individuals with HIV. In people living with HIV, regardless of treatment, age-related changes like arteriosclerosis are well-known to be accelerated. Such accelerated aging changes may decrease cerebral blood flow in younger generations with HIV, increasing the rate of occurrence of neurocognitive disorders. We investigated regional cerebral blood flows in well-controlled Japanese people living with HIV under 65 years old to clarify whether age-related changes in regional cerebral blood flows are accelerated in people living with HIV. Method: Japanese male HIV patients >20 years old but <65 years old who visited Teikyo University Hospital between August 2013 and September 2015 were recruited to and enrolled in this study. Healthy coeval male volunteers during the same period were recruited as controls. Magnetic resonance imaging was performed. Twelve regional cerebral blood flows were calculated from pseudocontinuous arterial spine labelling data. Results: Participants in this study comprised 40 individuals with HIV (HIV-positive group) and 33 non-HIV individuals (Control group). Median age was 40.15 years [interquartile range (IQR), 32.80-50.55 years] for the HIV-positive group and 48.00 years [IQR, 37.75-59.25 years; p  = 0.3585] for the Control group. No significant differences in regional cerebral blood flows were seen between groups. In the HIV-positive group, cerebral blood flows decreased with age in the neocortex, although no significant decrease was observed in any of the regions in the control group. Conclusions: Significant age-related declines in cerebral blood flows in the neocortex may occur earlier in HIV patients.

Background: The change in the prevalence of hypogonadism with age in men with human immunodeficiency virus (HIV) infection is subject to debate., Objective: To address this issue, we diagnosed hypogonadism based on serum levels of free testosterone (fTST) rather than total testosterone which is thought to be an inaccurate indicator. We also determined the relationship between age and fTST levels and identified risk factors for hypogonadism in men with HIV infection., Methods: We retrospectively reviewed fTST levels and associated clinical factors in 71 wellcontrolled HIV-infected men who were treated at Teikyo University Hospital between April 2015 and March 2016 and who had data available on serum fTST levels, measured >6 months after starting antiretroviral therapy. fTST was measured using radioimmunoassay on blood samples collected in the morning. Risk factors for hypogonadism were identified using Welch's t-test and multiple regression analysis., Results: The men had a mean (± standard deviation) age of 47.4 ± 13.6 years, and mean (± standard deviation) serum fTST level of 13.0 ± 6.1 pg/mL. Fifteen (21.1%) men had hypogonadism based on a fTST <8.5 pg/mL. Serum fTST levels significantly decreased with age (-0.216 pg/mL/year). Older age and low hemoglobin levels were identified as risk factors for hypogonadism., Conclusion: The men in the study experienced a more rapid decline in fTST levels with age than men in the general population (-0.161 pg/mL/year). Serum fTST levels in men with HIV infection should be monitored, especially in older men and those with low hemoglobin levels., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
