RESUMO

BACKGROUND AND OBJECTIVE: The influence of concomitant prednisolone on clinical outcomes and safety in infliximab-treated ulcerative colitis (UC) patients is unknown. DESIGN, SETTING, PARTICIPANTS AND OUTCOME MEASURES: A retrospective cohort study was performed, including 147 UC patients treated with infliximab at a tertiary inflammatory bowel disease (IBD) centre. Primary outcome was corticosteroid-free clinical remission (CFCR) at week 14 and week 52. Patients were grouped according to prednisolone tapering regimens: standard (≤5 mg/week), fast (>5 mg/week), direct discontinuation or no prednisolone. Patients intolerant to corticosteroids and patients stopping corticosteroids in preparation for surgery including colectomy during their initial admission were excluded. RESULTS: There was no overall association between prednisolone exposure or no exposure and CFCR at weeks 14 or 52 of infliximab. The proportion of patients with C reactive protein ≤5 mg/L was higher in the standard tapering at week 14 as compared with faster regimens or no prednisolone. In subgroup analyses, the standard tapering was associated with a higher rate of CFCR at week 14 compared with the fast-tapering regimen in patients receiving ≥40 mg prednisolone at initiation of infliximab (64.3% vs 26.3%, p=0.04) and among patients admitted with acute severe UC (66.6% vs 23.5%, p<0.05). Similar data were seen at week 52. Prednisolone did not affect infliximab trough levels but increased infection rates (10/77 vs 2/70, p=0.03), in particular C. difficile infection. CONCLUSION: In UC patients with limited disease burden, prednisolone did not affect effectiveness of infliximab. However, patients with increased disease burden seem to benefit from corticosteroid combination therapy.

RESUMO

PURPOSE OF REVIEW: Limited data is available for tapering or discontinuation of biologic therapy in patients with axSpA who are in disease remission. The current review concentrates on published studies regarding dose tapering or withdrawal of biologics in axSpA. RECENT FINDINGS: Recent evidence in light of randomized controlled trials suggests that tapering of b-DMARDs is a feasible strategy to maintain remission or low disease activity in axSpA patients. TNF inhibitors were the studied biologics in most of these trials. The disease flare rates were comparable to those maintained on standard dose in most of these studies, although with variable tapering strategies and follow-up. Additionally, the duration of disease in remission prior to tapering, studied primary outcome, and flare definitions were heterogeneous. Female sex, HLA-B*27 negativity, high physician global score, and high CRP were negative predictors of successful tapering, but not consistently reported in all the trials. Although designed to address efficacy, there were no safety concerns with b-DMARD tapering. Withdrawal or complete discontinuation of biologics met with increased risk of flares compared to standard dosing. Tapering of TNF inhibitors may be feasible in certain axSpA patients with an acceptable disease state; however, discontinuation is not currently recommended owing to increased risk of flare. Future studies with axSpA patients with longer remission duration prior to taper and different doses and types of b-DMARDs may provide more guidance.

RESUMO

RATIONALE: Opioid injection drug use (IDU) has been linked to a more severe pattern of use (e.g. tolerance, overdose risk) and shorter retention in treatment, which may undermine abstinence attempts. OBJECTIVES: This secondary data analysis of four human laboratory studies investigated whether current opioid IDU modulates subjective abuse liability responses to high-dose hydromorphone during intermediate-dose buprenorphine stabilization (designed to suppress withdrawal but allow surmountable agonist effects), and whether hydromorphone response magnitude predicts latency of return to opioid use during buprenorphine dose-tapering. METHODS: Regular heroin users not currently seeking treatment (n = 54; 29 current injectors, 25 non-injectors) were stabilized on 8-mg/day sublingual buprenorphine and assessed for subjective responses (e.g. 'liking', craving) to hydromorphone 24-mg intramuscular challenge (administered 16-hr post-buprenorphine) under randomized, double-blinded, controlled conditions. A subgroup (n = 35) subsequently completed a standardized 3-week outpatient buprenorphine dose-taper, paired with opioid-abstinent contingent reinforcement, and were assessed for return to opioid use based on thrice-weekly urinalysis and self-report. RESULTS: During buprenorphine stabilization, IDU reported lower 'liking' of buprenorphine and post-hydromorphone peak 'liking', 'good effect' and 'high' compared to non-IDU. Less hydromorphone peak increase-from-baseline in 'liking' (which correlated with less hydromorphone-induced craving suppression) predicted significantly faster return to opioid use during buprenorphine dose-tapering. CONCLUSIONS: In these buprenorphine-stabilized regular heroin users, IDU is associated with attenuated 'liking' response (more cross-tolerance) to buprenorphine and to high-dose hydromorphone challenge and, in turn, this cross-tolerance (but not IDU) predicts faster return to opioid use. Further research should examine mechanisms that link cross-tolerance to treatment response.

RESUMO

BACKGROUND: Tocilizumab in the treatment of rheumatoid arthritis (RA) is a potential candidate for concentration-guided tapering because the standard dose of tocilizumab results in a wide range of serum concentrations, usually above the presumed therapeutic window, and an exposure-response relationship has been described. However, no clinical trials have been published to date on this subject. Therefore, the objective of this study was to assess the feasibility of the tapering of intravenous (iv) tocilizumab with the use of a pharmacokinetic model-based algorithm in RA patients. METHODS: A randomized controlled trial with a double-blind design and follow-up of 24 weeks was conducted. RA patients who received the standard of tocilizumab for at least the past 24 weeks, which is 8 mg/kg every 4 weeks, were included. Patients with a tocilizumab serum concentration above 5 mg/L at trough were randomized between concentration-guided dose tapering, referred to as therapeutic drug monitoring (TDM), or the standard 8 mg/kg dose. In the TDM group, the tocilizumab dose was tapered with a recently published model-based algorithm to achieve a target concentration of 4-6 mg/L after 20 weeks of dose tapering. RESULTS: Twelve RA patients were included and 10 were randomized between the TDM and standard dose group. The study was feasible regarding the predefined feasibility criteria and patients had a positive attitude toward therapeutic drug monitoring. In the TDM group, the tocilizumab trough concentration within patients decreased on average by 24.5 ± 18.3 mg/L compared with a decrease of 2.8 ± 12 mg/L in the standard dose group. None of the patients in the TDM group reached the drug range of 4-6 mg/L. Instead, tocilizumab concentrations of 1.6 and 1.5 mg/L were found for the 2 patients who completed follow-up on the tapered dose. No differences in RA disease activity were observed between the 2 study groups. CONCLUSIONS: This study was the first to show that it is feasible to apply a dose-reduction algorithm based on a pharmacokinetic model in clinical practice. However, the current algorithm needs to be optimized before it can be applied on a larger scale.

RESUMO

BACKGROUND: More than half of patients with polymyalgia rheumatica have a relapse during tapering of glucocorticoid therapy. Previous studies have suggested that interleukin-6 blockade may be clinically useful in the treatment of polymyalgia rheumatica. Sarilumab, a human monoclonal antibody, binds interleukin-6 receptor α and efficiently blocks the interleukin-6 pathway. METHODS: In this phase 3 trial, we randomly assigned patients in a 1:1 ratio to receive 52 weeks of a twice-monthly subcutaneous injection of either sarilumab (at a dose of 200 mg) plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. The primary outcome at 52 weeks was sustained remission, which was defined as the resolution of signs and symptoms of polymyalgia rheumatica by week 12 and sustained normalization of the C-reactive protein level, absence of disease flare, and adherence to the prednisone taper from weeks 12 through 52. RESULTS: A total of 118 patients underwent randomization (60 to receive sarilumab and 58 to receive placebo). At week 52, sustained remission occurred in 28% (17 of 60 patients) in the sarilumab group and in 10% (6 of 58 patients) in the placebo group (difference, 18 percentage points; 95% confidence interval, 4 to 32; P = 0.02). The median cumulative glucocorticoid dose at 52 weeks was significantly lower in the sarilumab group than in the placebo group (777 mg vs. 2044 mg; P<0.001). The most common adverse events with sarilumab as compared with placebo were neutropenia (15% vs. 0%), arthralgia (15% vs. 5%), and diarrhea (12% vs. 2%). More treatment-related discontinuations were observed in the sarilumab group than in the placebo group (12% vs. 7%). CONCLUSIONS: Sarilumab showed significant efficacy in achieving sustained remission and reducing the cumulative glucocorticoid dose in patients with a relapse of polymyalgia rheumatica during glucocorticoid tapering.

RESUMO

CASE SUMMARY: A 73-year-old woman with hypertension controlled by an angiotensin-converting enzyme inhibitor (ACEi) undergoes a laparoscopic converted to open low anterior resection with diverting loop ileostomy (DLI) for locally advanced rectal adenocarcinoma. On postoperative day 5, her serum creatinine (sCr) is 1.4 mg/dL compared to a baseline of 0.9 mg/dL. Nonsteroidal anti-inflammatory drugs (NSAIDs) are stopped, she is resuscitated with balanced crystalloid until her sCr returns to the nadir, and she is discharged. At her postoperative visit, she has mild tachycardia and reports 1 week of 1500 to 2000 mL/day of ileostomy output. She is admitted with an sCr of 2.4 mg/dL and a blood urea nitrogen of 50. She is discharged after infectious complications are excluded, her ileostomy output is controlled, and her sCr is 1.7 mg/dL. Before initiation of adjuvant chemotherapy, her sCr is 1.8 mg/dL, and her estimated glomerular filtration rate (eGFR) is 28 to 32 mL/minute/1.73m2. This severe renal impairment prompts dose reduction of adjuvant chemotherapy.

RESUMO

BACKGROUND: Adverse events can occur after antipsychotic discontinuation but evidence from antipsychotic drug trials is scarce. We aimed to estimate the occurrence of adverse events after discontinuing antipsychotics. METHODS: For this two-stage individual participant data meta-analysis, we searched the Yale University Open Data Access Project's database for randomised controlled trials of antipsychotics from database inception until May 6, 2021. We included placebo-controlled antipsychotic randomised controlled trials with individual participant data of participants (aged ≥ 18 years, of any sex and ethnicity) with schizophrenia, schizoaffective disorder, or bipolar disorder. Studies were excluded if treatment with antidepressants, lithium, or antiepileptic drugs was initiated as additive therapy at the start of the placebo phase. Starting from the screening or washout phase, we divided participants who were randomised to placebo into two groups: the discontinuation group (participants who discontinued prestudy antipsychotics at the start of the screening or washout phase) and control group (participants who did not take prestudy antipsychotics for at least 4 weeks before the start of the screening or washout phase). Participants were excluded from the discontinuation and control groups if they discontinued prestudy treatment with antidepressants, lithium, or antiepileptic drugs up to 4 weeks before baseline, received an antipsychotic as a tolerability test, or received a long-acting injection of an antipsychotic within 12 weeks before baseline. In the discontinuation group, individuals were excluded if they discontinued prestudy antipsychotic treatment more than 3 days before, or any day after, the start of screening or washout phase. The prespecified primary outcome was occurrence of at least one new somatic adverse event with an onset within 4 weeks after the start of the screening or washout phase. We implemented a generalised linear model that accounted for potential confounders, to estimate the effect of antipsychotic discontinuation. This study is registered with PROSPERO (CRD42021224350). FINDINGS: We identified 409 records of which 18 were eligible and included in the analysis. From these 18 studies, 692 individuals (242 [35·0%] women and 450 [65·0%] men) were eligible for the discontinuation group and 935 individuals (339 [36·3%] women and 596 [63·7%] men) were eligible for the control group (median age in both groups: 39 years [IQR 30-47]). New somatic adverse events occurred in 295 (43%) individuals in the discontinuation group and 293 (31%) individuals in the control group (OR 1·74; 95% CI 1·27-2·39; τ2=0·15; moderate strength of evidence). New psychiatric adverse events were also more frequent in the discontinuation group than the control group (OR 2·01; 95% CI 1·38-2·94). Longer duration of treatment before discontinuation (OR for doubling the duration of treatment: 1·08; 95% CI 1·01-1·14) was associated with a higher probability of new somatic adverse events after antipsychotic discontinuation, and tapered discontinuation (compared with abrupt discontinuation: 0·54; 0·32-0·91) and no history of somatic illness (compared with history of somatic illness: 0·63; 0·43-0·91) were associated with lower probabilities of new somatic adverse events after antipsychotic discontinuation. The risk of bias was moderate in 13 (72·2%) studies and serious in five (27·8%) studies. INTERPRETATION: We detected moderate evidence of emerging somatic adverse events after discontinuation of first-generation and second-generation antipsychotics, particularly after discontinuation of longer durations of treatment. Tapered discontinuation can mitigate the risk of emerging somatic adverse events after antipsychotic discontinuation. These findings have implications for the safety of treatment discontinuation and could be used for tailored treatment planning. FUNDING: German Research Foundation.

RESUMO

Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease characterized by progressive scar tissue formation. An acute exacerbation of IPF (AE-IPF) is a clinically significant respiratory decompensation that accounts for a significant proportion of IPF-related morbidity and mortality. AE-IPF can be idiopathic or associated with pulmonary embolism, infection, aspiration, surgery, and drug toxicity. In this novel case report, we describe a potential association between AE-IPF and BNT162b2 mRNA COVID-19 vaccination that was successfully treated with a short course of glucocorticoids. While our aim is to raise awareness for this yet-to-be-described adverse event, immunization against vaccine-preventable disease remains widely recommended in vulnerable patients with chronic lung disease such as IPF.

RESUMO

OBJECTIVES: To understand the perspectives of patients and rheumatologists for tapering DMARDs in RA. METHODS: Using semi-structured interview guides, we conducted individual interviews and focus groups with RA patients and rheumatologists, which were audiotaped and transcribed. We conducted a pragmatic thematic analysis to identify major themes, comparing and contrasting different views on DMARD tapering between patients and rheumatologists. RESULTS: We recruited 28 adult patients with RA (64% women; disease duration 1-54 y) and 23 rheumatologists (52% women). Attitudes across both groups towards tapering DMARDs were ambivalent, ranging from wary to enthusiastic. Both groups expressed concerns, particularly the inability to 'recapture' the same level of disease control, while also acknowledging potential positive outcomes such as reduced drug harms. Patient tapering perspectives (whether to and when) changed over time and commonly included non-biologic DMARDs. Patient preferences were influenced by lived experiences, side effects, previous tapering experiences, disease trajectory, remission duration and current life roles. Rheumatologists' perspectives varied on timing and patient profile to initiate tapering, and were informed by both data and clinical experience. Patients expressed interest in shared decision-making (SDM) and close monitoring during tapering, with ready access to their health-care team if problems arose. Rheumatologists were generally open to tapering (not stopping), though sometimes only when requested by their patients. CONCLUSION: The perspectives of patients and rheumatologists on tapering DMARDs in RA vary and evolve over time. Rheumatologists should periodically discuss DMARD tapering with patients as part of SDM, and ensure monitoring and flare management plans are in place.

RESUMO

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.

RESUMO

Benzodiazepine and related sedative use has been increasing. There has been a growing number of unregulated novel psychoactive substances, including designer benzodiazepines. Benzodiazepines have neurobiological and pharmacologic properties that result in a high potential for misuse and physical dependence. Options for discontinuing long-term benzodiazepine use include an outpatient benzodiazepine taper or inpatient withdrawal management at a hospital or detoxification facility. The quality of evidence on medications for benzodiazepine discontinuation is overall low, whereas cognitive behavioral therapy has shown the most benefit in terms of behavioral treatments. Benzodiazepines may also have significant adverse effects, increasing the risk of overdose and death.

RESUMO

Abstract Vascular ulcers (VU) constitute a major cause of pain and disability, and significantly compromise quality of life. VU have a natural tendency to become chronic and in many cases exhibit anunsatisfactoryresponse to many of the standard therapeutic options.The case of a 73 year-old Caucasian female with severe pain and poorly-controlled pain (Visual Analogic Scale-VAS- of 8-9) due to three lower leg long-standing VUs is reported and discussed herein. The patient was treated with topical instillations of undiluted sevoflurane as per institutional off-label protocol (starting doses of 1mL/cm2 twice a day, and up-titrated according to response to a maximum of 7 mL twice daily). The VAS score dropped to 0-1 shortly after initiation of therapy and remained stable throughout treatment up until the closure of the observations. Subsequently, opioid therapy was gradually tapered down and ultimately abandoned.Sevoflurane application resulted on adequate and sustained pain management of refractory VU, with no significant side effects. On account of its beneficial effectivity and safety profiles, topical sevoflurane emerges as an add-on alternative for the long-term management of VU, and potentially other painful conditions.

RESUMO

Non-contrast cerebral computed tomography (CT) is frequently performed as a first-line diagnostic approach in patients with suspected ischemic stroke. The purpose of this study was to evaluate the performance of hybrid and model-based iterative image reconstruction for standard-dose (SD) and low-dose (LD) non-contrast cerebral imaging by multi-detector CT (MDCT). We retrospectively analyzed 131 patients with suspected ischemic stroke (mean age: 74.2 ± 14.3 years, 67 females) who underwent initial MDCT with a SD protocol (300 mAs) as well as follow-up MDCT after a maximum of 10 days with a LD protocol (200 mAs). Ischemic demarcation was detected in 26 patients for initial and in 64 patients for follow-up imaging, with diffusion-weighted magnetic resonance imaging (MRI) confirming ischemia in all of those patients. The non-contrast cerebral MDCT images were reconstructed using hybrid (Philips "iDose4") and model-based iterative (Philips "IMR3") reconstruction algorithms. Two readers assessed overall image quality, anatomic detail, differentiation of gray matter (GM)/white matter (WM), and conspicuity of ischemic demarcation, if any. Quantitative assessment included signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) calculations for WM, GM, and demarcated areas. Ischemic demarcation was detected in all MDCT images of affected patients by both readers, irrespective of the reconstruction method used. For LD imaging, anatomic detail and GM/WM differentiation was significantly better when using the model-based iterative compared to the hybrid reconstruction method. Furthermore, CNR of GM/WM as well as the SNR of WM and GM of healthy brain tissue were significantly higher for LD images with model-based iterative reconstruction when compared to SD or LD images reconstructed with the hybrid algorithm. For patients with ischemic demarcation, there was a significant difference between images using hybrid versus model-based iterative reconstruction for CNR of ischemic/contralateral unaffected areas (mean ± standard deviation: SD_IMR: 4.4 ± 3.1, SD_iDose: 3.5 ± 2.3, P < 0.0001; LD_IMR: 4.6 ± 2.9, LD_iDose: 3.2 ± 2.1, P < 0.0001).  In conclusion, model-based iterative reconstruction provides higher CNR and SNR without significant loss of image quality for non-enhanced cerebral MDCT.

RESUMO

The recommended starting dose of bosutinib is 500 mg/day for chronic-phase (CP) or accelerated-/blast-phase Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) resistant/intolerant to prior therapy. However, some patients may require dose reductions to manage the occurrences of adverse events (AEs). Bosutinib efficacy and safety were evaluated following dose reductions in a phase I/II study of Ph+ patients with CP CML resistant/intolerant to imatinib or imatinib plus dasatinib and/or nilotinib, and those with accelerated-/blast-phase CML or acute lymphoblastic leukemia after at least imatinib treatment. In all, 570 patients with ≥4 years' follow-up were included in this analysis. Among 144 patients who dose-reduced to bosutinib 400 mg/day (without reduction to 300 mg/day), 22 (15 %) had complete cytogenetic response (CCyR) before and after reduction, 40 (28 %) initially achieved CCyR after reduction, and 4 (3 %) only had CCyR before reduction. Among 95 patients who dose-reduced to bosutinib 300 mg/day, 23 (24 %) had CCyR before and after reduction, 13 (14 %) initially achieved CCyR after reduction, and 3 (3 %) only had CCyR before reduction. Results were similar to matched controls who remained on 500 mg/day, indicating dose reductions had not substantially affected efficacy. The incidence of treatment-emergent AEs was lower after dose reductions, particularly for gastrointestinal events. The incidence of hematologic toxicities generally was similar before and after dose reduction. The management of AEs with bosutinib through dose reduction can lead to improved/maintained efficacy and better tolerability; still, approximately half of patients on treatment at year 4 maintained a dose of ≥500 mg/day.

RESUMO

Coronavirus disease (COVID-19) infection attacks the mucosal structures of the respiratory tract, especially the bronchial mucosa and immune cells. The skin changes and manifestations related to COVID-19 infection remain not clearly understood. Cutaneous manifestations related to COVID-19 had been reported. Our patient manifested atypical cutaneous exanthem on her legs, with no other abnormalities found. We used oral azithromycin 500 mg, dexamethasone 0.5 mg, vitamin C 100 mg, and paracetamol 500 mg, which are available at Badak Baru Primary Health Care. The exanthem has improved after 10 days of treatment.

RESUMO

BACKGROUND: High-intensity glucocorticoid regimens are commonly used to induce and maintain remission in Juvenile Dermatomyositis but are associated with several adverse side-effects. Evidence-based treatment guidelines from North American and European pediatric rheumatology research societies both advocate induction with intravenous pulse steroids followed by high dose oral steroids (2 mg/kg/day), which are then tapered. This study reports the time to disease control with reduced glucocorticoid dosing. METHODS: We retrospectively reviewed the records at a single tertiary-care children's hospital of patients diagnosed with Juvenile Dermatomyositis between 2000 and 2014 who had a minimum of 2 years of follow-up. The primary outcome measure was time to control of muscle and skin disease. Additional outcome measures included glucocorticoid dosing, effect of treatment on height, frequency of calcinosis, and complications from treatment. RESULTS: Of the 69 patients followed during the study period, 31 fulfilled inclusion criteria. Median length of follow-up was 4.58 years, (IQR 3-7.5). Myositis control was achieved in a median of 7.1 months (IQR 0.9-63.4). Cutaneous disease control was achieved in a median of 16.7 months (IQR 4.3-89.5). The median starting dose of glucocorticoids was 0.85 mg/kg/day, (IQR 0.5-1.74). The median duration of steroid treatment was 9.1 months, (IQR 4.7-17.4), while the median duration of any pharmacotherapy was 29.2 months (IQR 10.4 to 121.3). Sustained disease control off medications was achieved in 21/31 (68%) patients by the end of review. Persistent calcinosis was identified in only one patient (3%). CONCLUSION: Current accepted treatment paradigms for Juvenile Dermatomyositis include oral glucocorticoids beginning at 2 mg/kg/day and reduced over a prolonged time period. However, our results suggest that treatment using reduced doses and duration with early use of steroid-sparing agents is comparably effective in achieving favorable outcomes in Juvenile Dermatomyositis.

RESUMO

OBJECTIVES: To compare patient-reported side effects and tolerability of full-dose Bacillus Calmette-Guérin (BCG), reduced-dose BCG, and gemcitabine one week after administration. METHODS: All patients from July 2019 to November 2020 receiving intravesical therapy (IVT) for non-muscle invasive bladder cancer (NMIBC) at our institution were surveyed before repeat instillation. Survey questions recorded IVT retention times and the duration and severity of the following side effects: bladder symptoms, fatigue, body aches, hematuria, fever, chills, and other. All responses were collected and quantified in a de-identified, password-protected database. Statistical analysis was performed using SAS JMP 13. RESULTS: Of 592 surveys completed, symptoms of any kind were reported on 463 surveys (78%) with the most common symptoms including bladder symptoms (59%), fatigue (52%), body aches (26%), and hematuria (18%). Patients were able to hold full-dose BCG, reduced-dose BCG, and gemcitabine for the protocol-specified duration 87%, 95%, and 71% of the time (P <0.05). The prevalence, severity, and duration of body aches were highest with gemcitabine (P <0.05) while the prevalence and duration of hematuria were higher with BCG (P <0.05). Reduced-dose BCG had the lowest prevalence, severity, and duration of fatigue (P <0.05). CONCLUSION: Significant differences in the side effects and tolerability of full-dose BCG, reduced-dose BCG, and gemcitabine were demonstrated using this novel survey, and these differences are of value for informing IVT selection. Evaluation of IVTs other than gemcitabine and BCG will further inform selection of therapies for NMIBC.

RESUMO

OBJECTIVE: To compare the incidence, severity, and clinical course of frequently reported adverse events (AEs) after treatment with smoking cessation pharmacotherapies. METHODS: This was a multinational, multicenter, post hoc analysis of frequently reported treatment-emergent AEs from a large, phase 4, double-blind, randomized, triple-dummy, placebo-controlled trial (EAGLES), conducted between November 30, 2011, and January 13, 2015, that included smokers with and without psychiatric disorders (N=8144). Treatments were varenicline 1 mg twice daily, bupropion sustained-release 150 mg twice daily, and nicotine patch 21 mg once daily with tapering (12-week treatment, 12-week nontreatment follow-up), with incidence, time to onset, and duration of frequently reported AEs (≥5% of participants in any treatment group) measured. Risk differences for AEs for varenicline and bupropion vs nicotine patch were compared. RESULTS: Across frequently reported AEs, nausea, insomnia, abnormal dreams, anxiety, irritability, dry mouth, fatigue, and application site pruritus differed significantly in active treatment vs placebo groups. Risk differences were as follows: for nausea with varenicline vs nicotine patch, 15.50% (95% CI, 13.20% to 17.80%); for insomnia with bupropion vs nicotine patch, 2.58% (CI, 0.65% to 4.51%); and for abnormal dreams with varenicline and bupropion vs nicotine patch, -2.49% (CI, -4.35% to -0.64%) and -5.60% (CI, -7.27% to -3.93%), respectively. Frequently reported AEs of severe intensity and treatment discontinuation were experienced by less than 1.5% and less than 3% of participants across all groups, respectively. CONCLUSION: Active treatments were well tolerated with comparable AE profiles. Most AEs are not clinically important, and prescribers can reassure patients that those experienced will be manageable.

RESUMO

Aim: To determine whether de-escalating from advanced insulin therapy (AIT) to the combined use of metformin, an SGLT2 inhibitor, a GLP1 receptor agonist and basal insulin is the better option than multiple daily insulin injections (MDI) in obese patients with poorly controlled T2DM. Methods: This was a 16-week, prospective, randomized, controlled trial. Twenty-two obese patients with T2DM on AIT were randomized to intervention (step-down) or control (MDI) group. In the intervention group, all prandial insulin injections were discontinued, but the patient remained on basal insulin and metformin, to which an SGLT2i and a GLP1 RA were added. In the control group, the patient remained on MDI. Results: Compared to control group (n = 8), A1c was significantly lower at week 4 (9.54% vs 8.25%; p = .0088) and week 16 (9.7% vs 7.31%; p < .001) in intervention group (n = 10). In intervention group, compared to baseline, there was a significant decrease in weight (-16.38 pounds; p = .003), BMI (-3.06; p < .001), LDL cholesterol (-15.7 mg/dl; p = .0378), total cholesterol (-18.5 mg/dl; p = .0386), total daily insulin dose (-57.3 units; p < .001) and a significant improvement in DM-SAT patient satisfaction 0-100 scores: total score (+45.3; p < .001) and subscale scores (Convenience + 35.28, p = .019; Lifestyle + 35.8, p = .0052; Medical control + 51.3, p < .001; Wellbeing + 47.2, p = .0091) at week 16. Conclusion: De-escalating from AIT to the combined use of metformin, SGLT2i, GLP1 RA and basal insulin in obese patients with poorly controlled T2DM on MDI resulted in significant improvement in glycaemic control, weight loss and significantly higher patient satisfaction. This stepping-down approach may be the better option than continuing MDI in these patients.
