ABSTRACT

PURPOSE: To examine the impact of golimumab, on work productivity, activity limitation, and quality of life (QoL) in patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). METHODS: This real-world, multicenter, prospective study consecutively enrolled adult consented work-active patients with axSpA or PsA, newly initiated on golimumab as per the approved label. Prior receipt of > 1 prior biologic, or switching from another tumor-necrosis factor inhibitor due to primary non-response or safety reasons was not allowed. The Work Productivity and Activity Impairment-Specific Health Problem and the EuroQol 5-Dimensions (EQ-5D)-5-Level instruments were completed by the patients to assess the impact of golimumab on work productivity and activity impairment, and generic QoL, respectively. RESULTS: Overall, 121 eligible patients (mean age: 45.4 years; median disease duration: 11.3 months), 51 diagnosed with PsA and 70 with axSpA, were enrolled by 19 rheumatologists. Over a 11.9-month median observation period, < 1% of injections were missed (as collected by patient diaries), and the 12-month golimumab retention rate was 91.7%. At 3, 6, and 12 months post baseline, in the overall population, work productivity loss improved by a median of 31.4%, 44.2%, and 50.0%; activity impairment improved by 40.0%, 40.0%, and 50.0%; and the EQ-5D UK-weighted utility index improved by 0.24, 0.32, and 0.36 points, respectively (p < 0.001 for all). Statistically significant improvements in these measures were also noted in the PsA and axSpA subpopulations. CONCLUSION: In the routine care in Greece, golimumab displays beneficial effects on work productivity, daily activities, and QoL in work-active patients with axSpA and PsA. TRIAL REGISTRATION: Trial registration number and date of registration: As per the local regulations the study has been registered at the national registry for non-interventional studies https://www.dilon.sfee.gr/studiesp_d.php?meleti_id=MK8259-6083 .

ABSTRACT

This study aimed at assessing the impact of golimumab on health-related quality of life (HRQoL) and other patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) in real-world settings. GO-Q was an observational, prospective, 12-month study, which recruited patients with moderate-to-severely active RA initiating golimumab treatment per label in rheumatology clinics and private practices. Primary endpoint was the change in PROs [EuroQol-5 Dimensions-3 Levels (EQ-5D-3L) questionnaire, Health Assessment Questionnaire Disease Index (HAQ-DI), and Work Productivity and Activity Index for RA (WPAI:RA)] after 12 months of treatment. Other endpoints included Disease Activity Score for 28 joints with erythrocyte sedimentation rate (DAS28-ESR), healthcare resource utilization, and golimumab adherence. Changes in continuous variables from baseline were evaluated with the paired t test. One hundred forty-five patients were recruited. The mean [standard deviation (SD)] EQ-5D-3L index increased significantly at 12 months versus baseline [from 0.427 (0.206) to 0.801 (0.229); p < 0.0001], with changes as early as 3 and 6 months (both p < 0.0001). Accordingly, there were statistically significant changes in all WPAI:RA domains from baseline to 3, 6, and 12 months (p < 0.0001). Patients' function improved gradually from the third month until the end of follow-up (p < 0.0001 for all time-points). Thirty (27.3%) and 60 (54.6%) patients achieved remission (DAS28-ESR < 2.6) and low disease activity (DAS28-ESR ≤ 3.2), respectively, at 12 months. Adherence rate to golimumab was high (mean [SD] 90.3% (7.5) at 12 months). In patients with moderate-to-severely active RA, golimumab significantly improved HRQoL, physical function, and work productivity and activity, with improvements in disease activity over 12 months in real-world settings.

ABSTRACT

Parkinson's disease (PD) is a neurodegenerative disorder classically characterized by the death of dopamine (DA) neurons in the substantia nigra pars compacta and by intracellular Lewy bodies composed largely of α-synuclein. Approximately 5-10% of PD patients have a familial form of Parkinsonism, including mutations in α-synuclein. To better understand the cell-type specific role of α-synuclein on DA neurotransmission, and the effects of the disease-associated A30P mutation, we generated and studied a novel transgenic model of PD. We expressed the A30P mutant form of human α-synuclein in a spatially-relevant manner from the 111kb SNCA genomic DNA locus on a bacterial artificial chromosome (BAC) insert on a mouse null (Snca-/-) background. The BAC transgenic mice expressed α-synuclein in tyrosine hydroxylase-positive neurons and expression of either A30P α-synuclein or wildtype α-synuclein restored the sensitivity of DA neurons to MPTP in resistant Snca-/- animals. A30P α-synuclein mice showed no Lewy body-like aggregation, and did not lose catecholamine neurons in substantia nigra or locus coeruleus. However, using cyclic voltammetry at carbon-fiber microelectrodes we identified a deficit in evoked DA release in the caudate putamen, but not in the nucleus accumbens, of SNCA-A30P Snca-/- mice but no changes to release of another catecholamine, norepinephrine (NE), in the NE-rich ventral bed nucleus of stria terminalis. SNCA-A30P Snca-/- mice had no overt behavioral impairments but exhibited a mild increase in wheel-running. In summary, this refined PD mouse model shows that A30P α-synuclein preferentially perturbs the dopaminergic system in the dorsal striatum, reflecting the region-specific change seen in PD.

ABSTRACT

Cellular and humoral immunity exhibit dynamic adaptation to the mutating SARS-CoV-2 virus. It is noteworthy that immune responses differ significantly, influenced by whether a patient has received vaccination or whether there is co-occurrence of naturally acquired and vaccine-induced immunity, known as hybrid immunity. The different immune reactions, conditional on vaccination status and the viral variant involved, bear implications for inflammatory responses, patient outcomes, pathogen transmission rates, and lingering post-COVID conditions. Considering these developments, we have performed a review of recently published literature, aiming to disentangle the intricate relationships among immunological profiles, transmission, the long-term health effects post-COVID infection poses, and the resultant clinical manifestations. This investigation is directed toward understanding the variability in the longevity and potency of cellular and humoral immune responses elicited by immunization and hybrid infection.

ABSTRACT

The ongoing COVID-19 pandemic has significantly impacted special populations, including immunocompromised individuals, people living with HIV (PLWHIV), pediatric patients, and those with chronic liver disease (CLD). This scoping review aims to map the clinical outcomes of these vulnerable groups when infected with various SARS-CoV-2 variants. The review identifies trends and patterns, noting that early variants, such as Alpha and Delta, are associated with more severe outcomes, including higher hospitalization and mortality rates. In contrast, the Omicron variant, despite its increased transmissibility, tends to cause milder clinical manifestations. The review highlights the necessity for ongoing surveillance and tailored healthcare interventions due to the heterogeneity of patient populations and the evolving nature of the virus. Continuous monitoring and adaptive healthcare strategies are essential to mitigate the impact of COVID-19 on these high-risk groups.

ABSTRACT

BACKGROUND AND AIMS: This real-world study assessed the impact of golimumab on health-related quality of life (HRQoL) and other patient-reported outcomes (PROs) in patients with ulcerative colitis over 12 months in Greece. METHODS: GO-LIFE was a noninterventional, prospective, multicenter, 12-month study. Patients who had moderately-to-severely active ulcerative colitis were naïve to antitumor necrosis factor (anti-TNFα) therapy and had failed previous conventional therapy. Patients received golimumab as per label. The primary endpoint was patients achieving inflammatory bowel disease questionnaire 32-item (IBDQ-32) remission at 12 months. Secondary endpoints, at 6 and 12 months, included patients achieving IBDQ-32 response; the mean change in the treatment satisfaction questionnaire for medication (TSQM) and the work productivity and activity impairment in ulcerative colitis (WPAI:UC) questionnaires; changes in healthcare utilization; patients achieving clinical response and remission; adherence rates and the percentage of patients who discontinued golimumab. RESULTS: IBDQ-32 remission was achieved by 76.9% of patients at 12 months. Mean changes in all TSQM and WPAI:UC domain scores at 12 months were statistically significant. Clinical remission was achieved by 49.4 and 50.6% of patients at 6 and 12 months, and clinical response by 59.3 and 56.8%, respectively. All patients but one (80/81) had high adherence (≥80%) to golimumab treatment over 12 months. Ulcerative colitis-related health care resource utilization was reduced during the follow-up period. CONCLUSIONS: In real-world settings, treatment with golimumab resulted in meaningful improvements in HRQoL and other PROs, and in disease activity at 6 and 12 months in patients with moderately-to-severely active ulcerative colitis who were naïve to anti-TNFa therapy.

ABSTRACT

The microtubule-associated protein tau is implicated in various neurodegenerative diseases including Alzheimer's disease, progressive supranuclear palsy and corticobasal degeneration, which are characterized by intracellular accumulation of hyperphosphorylated tau. Mutations in the tau gene MAPT cause frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17). In the human central nervous system, six tau isoforms are expressed, and imbalances in tau isoform ratios are associated with pathology. To date, few animal models of tauopathy allow for the potential influence of these protein isoforms, relying instead on cDNA-based transgene expression. Using the P1-derived artificial chromosome (PAC) technology, we created mouse lines expressing all six tau isoforms from the human MAPT locus, harbouring either the wild-type sequence or the disease-associated N296H mutation on an endogenous Mapt-/- background. Animals expressing N296H mutant tau recapitulated early key features of tauopathic disease, including a tau isoform imbalance and tau hyperphosphorylation in the absence of somatodendritic tau inclusions. Furthermore, N296H animals displayed behavioural anomalies such as hyperactivity, increased time in the open arms of the elevated plus maze and increased immobility during the tail suspension test. The mouse models described provide an excellent model to study the function of wild-type or mutant tau in a highly physiological setting.

ABSTRACT

Sleep and circadian rhythm disruption is frequently associated with neurodegenerative disease, yet it is unclear how the specific pathology in these disorders leads to abnormal rest/activity profiles. To investigate whether the pathological features of lysosomal storage disorders (LSDs) influence the core molecular clock or the circadian behavioural abnormalities reported in some patients, we examined mouse models of Niemann-Pick Type-C (Npc1 mutant, Npc1(nih)) and Sandhoff (Hexb knockout, Hexb(-/-)) disease using wheel-running activity measurement, neuropathology and clock gene expression analysis. Both mutants exhibited regular, entrained rest/activity patterns under light:dark (LD) conditions despite the onset of their respective neurodegenerative phenotypes. A slightly shortened free-running period and changes in Per1 gene expression were observed in Hexb(-/-) mice under constant dark conditions (DD); however, no overt neuropathology was detected in the suprachiasmatic nucleus (SCN). Conversely, despite extensive cholesterol accumulation in the SCN of Npc1(nih) mutants, no circadian disruption was observed under constant conditions. Our results indicate the accumulation of specific metabolites in LSDs may differentially contribute to circadian deregulation at the molecular and behavioural level.

ABSTRACT

Sleep and circadian rhythm disruption has been widely observed in neuropsychiatric disorders including schizophrenia [1] and often precedes related symptoms [2]. However, mechanistic basis for this association remains unknown. Therefore, we investigated the circadian phenotype of blind-drunk (Bdr), a mouse model of synaptosomal-associated protein (Snap)-25 exocytotic disruption that displays schizophrenic endophenotypes modulated by prenatal factors and reversible by antipsychotic treatment [3, 4]. Notably, SNAP-25 has been implicated in schizophrenia from genetic [5-8], pathological [9-13], and functional studies [14-16]. We show here that the rest and activity rhythms of Bdr mice are phase advanced and fragmented under a light/dark cycle, reminiscent of the disturbed sleep patterns observed in schizophrenia. Retinal inputs appear normal in mutants, and clock gene rhythms within the suprachiasmatic nucleus (SCN) are normally phased both in vitro and in vivo. However, the 24 hr rhythms of arginine vasopressin within the SCN and plasma corticosterone are both markedly phase advanced in Bdr mice. We suggest that the Bdr circadian phenotype arises from a disruption of synaptic connectivity within the SCN that alters critical output signals. Collectively, our data provide a link between disruption of circadian activity cycles and synaptic dysfunction in a model of neuropsychiatric disease.
