De-escalation from Dose-Intensified Anti-TNF Therapy Is Successful in the Majority of IBD Patients at 12 Months.

BACKGROUND: Data on outcomes following de-escalation of intensified anti-TNF therapy in inflammatory bowel disease (IBD) are limited and concerns about relapse limit willingness to de-escalate. AIMS: To evaluate rates of successful de-escalation at 12 months and to determine factors that may predict success. METHODS: Single-centre experience of IBD patients that were de-escalated following deep remission on dose-intensified infliximab (IFX) or adalimumab (ADA) for secondary loss of response. Patients were classified as 'successes' if remaining on reduced anti-TNF or 'failures' if requiring re-escalation, steroids, surgery or enrolment into a clinical trial at 12 months. Patient demographics, disease characteristics, biomarkers (faecal calprotectin, C-reactive protein, albumin) and anti-TNF drug levels were collected 6-monthly. RESULTS: Of 25 patients (20 CD, 5 UC), 16 (64%) were successes 12 months post-de-escalation. Median time to failure was 6 months. Six of the nine failures required anti-TNF re-escalation and three entered a clinical trial. Re-escalation recaptured response in all six patients. There was no significant difference in baseline biomarker activity between the two groups. There was no difference in infliximab levels between successes and failures at the time of de-escalation (5.5 vs. 5.3, p = 0.63) as well as 6 months (3.1 vs. 4.6, p = 0.95) and 12 months (3.2 vs. 4.5, p = 0.58) post-de-escalation. CONCLUSION: Nearly two-thirds of patients remained on reduced anti-TNF dosing 12 months after de-escalation. All patients who failed de-escalation were recaptured after dose re-escalation. De-escalation with close monitoring may be considered in patients on intensified anti-TNF therapy in sustained remission.

Flares after hydroxychloroquine reduction or discontinuation: results from the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort.

OBJECTIVES: To evaluate systemic lupus erythematosus (SLE) flares following hydroxychloroquine (HCQ) reduction or discontinuation versus HCQ maintenance. METHODS: We analysed prospective data from the Systemic Lupus International Collaborating Clinics (SLICC) cohort, enrolled from 33 sites within 15 months of SLE diagnosis and followed annually (1999-2019). We evaluated person-time contributed while on the initial HCQ dose ('maintenance'), comparing this with person-time contributed after a first dose reduction, and after a first HCQ discontinuation. We estimated time to first flare, defined as either subsequent need for therapy augmentation, increase of ≥4 points in the SLE Disease Activity Index-2000, or hospitalisation for SLE. We estimated adjusted HRs (aHRs) with 95% CIs associated with reducing/discontinuing HCQ (vs maintenance). We also conducted separate multivariable hazard regressions in each HCQ subcohort to identify factors associated with flare. RESULTS: We studied 1460 (90% female) patients initiating HCQ. aHRs for first SLE flare were 1.20 (95% CI 1.04 to 1.38) and 1.56 (95% CI 1.31 to 1.86) for the HCQ reduction and discontinuation groups, respectively, versus HCQ maintenance. Patients with low educational level were at particular risk of flaring after HCQ discontinuation (aHR 1.43, 95% CI 1.09 to 1.87). Prednisone use at time-zero was associated with over 1.5-fold increase in flare risk in all HCQ subcohorts. CONCLUSIONS: SLE flare risk was higher after HCQ taper/discontinuation versus HCQ maintenance. Decisions to maintain, reduce or stop HCQ may affect specific subgroups differently, including those on prednisone and/or with low education. Further study of special groups (eg, seniors) may be helpful.

Association Between Adaptive Servo-Ventilation Therapy and Renal Function.

Cardio-renal syndrome is a challenging clinical entity to manage, and is often associated with increased morbidity and mortality. We hypothesized that adaptive servo-ventilation (ASV), non-invasive positive pressure ventilation that ameliorates systemic/pulmonary congestion, may improve renal function in patients with symptomatic heart failure complicated by the cardio-renal syndrome. Patients with symptomatic congestive heart failure who underwent ASV therapy for over 1 month were included in this retrospective study. The trajectory of the estimated glomerular filtration ratio (eGFR) between the pre-1 month period and the post-one-month period (on ASV) were compared. A total of 81 patients (median 65 years old, 65 men) were included. eGFR decreased during the pre-1 month period from 52.7 (41.7, 64.6) down to 49.9 (37.3, 63.5) mL/minute/1.73 m2 (P < 0.001) whereas we observed an increase following one-month of ASV therapy up to 53.4 (38.6, 68.6) mL/minute/1.73 m2 (P = 0.022). A reduction in furosemide equivalent dose following the initiation of ASV therapy was independently associated with increases in eGFR with an adjusted odds ratio of 13.72 (95% confidence interval 3.40-55.3, P < 0.001). In conclusion, short-term ASV therapy was associated with the preservation of renal function, particularly when the dose of loop diuretics was concomitantly reduced.

Predictive factors of relapse after dose reduction of oral 5-aminosalicylic acid in patients with ulcerative colitis in the remission phase.

OBJECTIVES: Useful indices to determine whether to reduce the dose of 5-aminosalicylic acid (5-ASA) in patients with ulcerative colitis (UC) during remission remain unclear. We aimed to analyze the rate and risk factors of relapse after reducing the dose of oral 5-ASA used for maintenance therapy of UC. METHODS: UC patients whose 5-ASA dose was reduced in clinical remission (partial Mayo score of ≤ 1) at our institution from 2012 to 2017 were analyzed. Various clinical variables of patients who relapsed after reducing the dose of oral 5-ASA were compared with those of patients who maintained remission. Risk factors for relapse were assessed by univariate and multivariate logistic regression analyses. Cumulative relapse-free survival rates were calculated using the Kaplan-Meier method. RESULTS: A total of 70 UC patients were included; 52 (74.3%) patients maintained remission and 18 (25.7%) patients relapsed during the follow-up period. Multivariate analysis indicated that a history of acute severe UC (ASUC) was an independent predictive factor for clinical relapse (p = 0.024, odds ratio: 21, 95% confidence interval: 1.50-293.2). Based on Kaplan-Meier survival analysis, the cumulative relapse-free survival rate within 52 weeks was 22.2% for patients with a history of ASUC, compared with 82.0% for those without. the log-rank test showed a significant difference in a history of ASUC (p < 0.001). CONCLUSIONS: Dose reduction of 5-ASA should be performed carefully in patients who have a history of ASUC.

Long-term safety and efficacy of sarilumab over 5 years in patients with rheumatoid arthritis refractory to TNF inhibitors.

OBJECTIVE: The objective of this study was to evaluate the long-term safety and efficacy of sarilumab over 5 years in patients with RA refractory to TNF inhibitors (TNFis). METHODS: Patients in the 24-week randomized controlled trial (RCT) TARGET (NCT01709578) who received double-blind placebo or sarilumab 150 or 200 mg every 2 weeks (q2w), plus conventional synthetic DMARDs (csDMARDs), were eligible to receive open-label sarilumab 200 mg q2w plus csDMARDs in the open-label extension (OLE), EXTEND (NCT01146652). OLE dose reduction to 150 mg q2w was permitted per investigators' judgement or protocol-mandated safety concerns. Safety and efficacy were assessed through treatment-emergent adverse events (AEs), laboratory abnormalities and clinical DASs. All statistics are descriptive. RESULTS: Of 546 patients, 454 (83%) were treated with sarilumab in the OLE. The cumulative observation period was 1654.8 patient-years (PY; n = 521); 268 patients (51%) had ≥4 years' exposure. Incidence rates per 100 PY of AEs, and AEs leading to discontinuation, infection and serious infection were 160.4, 8.1, 57.8 and 3.9, respectively. Neutropenia was the most common AE (15.3 per 100 PY). An absolute neutrophil count of <1000 cells/mm3 (Grade 3/4 neutropenia) was observed in 74 patients (14.2%) and normalized on treatment in 48. Clinical efficacy was sustained through 5 years' follow-up. Efficacy was similar for patients with 1 and >1 TNFi failure, and similar for patients who either remained on 200 mg or reduced to 150 mg. CONCLUSION: In patients with RA refractory to TNFi, sarilumab's long-term term safety profile was consistent with previous clinical studies and post-marketing reports. Efficacy was sustained over 5 years.

Eltrombopag second-line therapy in adult patients with primary immune thrombocytopenia in an attempt to achieve sustained remission off-treatment: results of a phase II, multicentre, prospective study.

Up to 30% immune thrombocytopenia (ITP) patients achieve a sustained remission off-treatment (SROT) after discontinuation of thrombopoietin receptor agonists (TPO-RAs). Factors predictive of response are lacking. Patients aged ≥18 years with newly diagnosed or persistent ITP were treated with eltrombopag for 24 weeks. Primary end-point was SROT: the proportion of responders that were able to taper and discontinue eltrombopag maintaining the response during a period of observation (PO) of six months. Secondary end-points included the association between some immunological parameters (TPO serum levels, cytokines and lymphocyte subsets) and response. Fifty-one patients were evaluable. Primary end-point was achieved in 13/51 (25%) treated patients and 13/34 (38%) patients who started the tapering. Baseline TPO levels were not associated with response at week 24 nor with SROT. Higher baseline levels of IL-10, IL-4, TNF-α and osteopontin were negative factors predictive of response (P = 0·001, 0·008, 0·02 and 0·03 respectively). This study confirms that SROT is feasible for a proportion of ITP patients treated with eltrombopag. Some biological parameters were predictive of response.

Current state of hypnotic use disorders: Results of a survey using the Japanese version of Benzodiazepine Dependence Self-Report Questionnaire.

AIMS: Benzodiazepine receptor agonists (BZ-RAs) are frequently prescribed to treat insomnia; however, their long-term use is not recommended. To introduce an appropriate pharmaco-therapy, the current state and background factors of BZ-RAs' dependence must be elucidated. In this study, we developed a Japanese version of the Benzodiazepine Dependence Self-Report Questionnaire (Bendep-SRQ-J) and conducted a study of BZ-RAs' use disorder. METHODS: The Bendep-SRQ-J was created with permission from the original developer. Subjects were inpatients and outpatients receiving BZ-RAs between 2012 and 2013. Clinical data collected were Bendep-SRQ-J scores, sleep disorders for which BZ-RAs were prescribed, physical comorbidities, psychotropic drugs, and lifestyle factors. Logistic analysis was performed to extract factors associated with severe symptoms. RESULTS: Of the 707 patients prescribed BZ-RAs, 324 had voluntarily tapered or discontinued their drugs. Logistic analysis showed that the total number of drugs administered in the last 6 months correlated with both worsening of symptoms or conditions. This was more notable among younger patients, and the proportion of patients with severe symptoms or conditions increased with the increasing number of drugs. CONCLUSION: Using the Bendep-SRQ-J, we elucidated the current state of BZ-RA dependence. Nearly half of the patients were non-compliant. The proportion of patients with severe symptoms or disease conditions increased with the increase in the number of drugs administered. These findings highlight the need for clinicians to be aware of the likelihood of benzodiazepine dependence, especially in young patients and patients prescribed multiple hypnotics.

Immediate versus wait-and-gradual discontinuation in antipsychotic switching: A meta-analysis.

INTRODUCTION: In two previous meta-analyses of randomized controlled trials (RCTs) examining antipsychotic switching strategies in patients with schizophrenia, we showed no significant differences in any clinical outcomes between immediate versus gradual and gradual versus wait-and-gradual discontinuation of the pre-switch antipsychotic. In this report, we compared immediate versus wait-and-gradual antipsychotic discontinuation. METHODS: We identified five RCTs examining immediate versus wait-and-gradual discontinuation of the pre-switch antipsychotic in antipsychotic switching involving patients with schizophrenia. However, no data were available from one RCT. The following clinical outcome data were extracted and meta-analyzed: study discontinuation, psychopathology, extrapyramidal symptoms, and treatment-emergent adverse events that were reported in two or more of the studies. RESULTS: The meta-analysis included four RCTs involving 351 patients (n=175 for immediate and n=176 for wait-and-gradual antipsychotic discontinuation). A significant difference was found in study discontinuation due to all causes (n=4, n=351, risk ratio=1.58, 95% confidence interval 1.15-2.17, p=0.005, I2=0%) between the immediate and wait-and-gradual antipsychotic discontinuation groups, while there was no significant difference in any other clinical outcomes. The group difference in study discontinuation due to all causes remained significant for the studies adopting immediate antipsychotic initiation but not for the studies switching to ziprasidone. CONCLUSION: Findings suggest that wait-and-gradual antipsychotic discontinuation may be preferable when a more cautious antipsychotic switch is needed. However, further long-term, double-blind RCTs are needed to confirm the present findings.

The effect of an mHealth intervention for titration of insulin for type 2 diabetes: A pilot study.

BACKGROUND: Stabilising blood glucose levels (BGL) after starting or changing insulin and related therapies can be challenging for diabetes services and the patient with type 2 diabetes. Traditionally, a credentialled diabetes educator (CDE) would talk with the patient over the phone to obtain a history of their BGLs over the previous week and provide advice on the insulin dose adjustments as required. This study trialled a smartphone application for sharing BGLs, with the ability to digitally transmit advice back to patients compared with their usual care. AIMS: The aim of this study was to compare desirability, efficiency and ease of use. METHODS: Participants were enrolled in either the traditional (n=50) or Health2Sync (H2S) (n=42) treatment group by patient preference. All insulin stabilisations were conducted by the CDE. Descriptive statistics were used for analysis. RESULTS: The average total time taken to titrate patients was similar in both groups (p>0.05), however there were fewer failure of contacts reported with H2S (p<0.01) and time per interaction was also lower (p<0.01). Sensitivity analysis revealed that, excluding the influence of no contacts, H2S patients had a lower average time for titration (p<0.01). There was no difference in clinical outcomes as measured by HbA1c between the two groups (p=0.75). CONCLUSION: We demonstrated a high acceptance and clinical utility of the H2S application. Clinicians were happy to use H2S and found it easy and convenient for most patients. Importantly, this reduced frequency of contacts with patients, time per interaction and average time for titration (p<0.01). Patient selection for this communication intervention is important.
