Treatment patterns and outcomes of older patients with mantle cell lymphoma in an Asian population.

BACKGROUND: Significant progress has been made in the treatment outcomes of mantle cell lymphoma (MCL) since the introduction of cytarabine and rituximab in modern regimens. However, older patients may not readily tolerate these agents nor derive benefit. We investigated the impact of age on treatment patterns and clinical outcomes of MCL patients in an Asian population. METHODS: A retrospective study was conducted on patients (n = 66) diagnosed with MCL at the National Cancer Centre Singapore between 1998 and 2018. The median follow-up duration was 40 months. Survival analyses were performed using the Kaplan-Meier method and multivariate Cox proportional models. RESULTS: The median age of the cohort was 59 years (range, 26-84), with a male predominance (73%). The majority (86%) had advanced stage 3-4 disease at diagnosis. Compared with younger patients, older patients aged ≥60 years (n = 32; 48.5%) presented more frequently with B-symptoms (75% vs 38%, p = 0.0028), anaemia (75% vs 35%, p = 0.0013), and carried higher prognostic risk scores (sMIPI high risk 84% vs 56%, p = 0.016). Non-cytarabine-based induction chemotherapy was more commonly administered in older patients (76% vs 32%, p = 0.0012). The 5-year overall survival (OS) and progression-free survival (PFS) was 68 and 25% respectively. In a multivariable model, older age (HR 3.42, 95%CI 1.48-7.92, p = 0.004) and anemia (HR 2.56, 95%CI 1.10-5.96, p = 0.029) were independently associated with poorer OS while older age (HR 2.24, 95%CI 1.21-4.14, p = 0.010) and hypoalbuminemia (HR 2.20, 95%CI 1.17-4.13, p = 0.014) were independently associated with poorer PFS. In an exploratory analysis, maintenance rituximab following induction chemotherapy improved PFS in younger patients, with median PFS of 131 months and 45 months with or without maintenance therapy respectively (HR 0.39, 95%CI 0.16-0.93, p = 0.035). In contrast, no survival benefit was observed in older patients. CONCLUSIONS: We demonstrated in our analysis that older patients with MCL may harbor adverse clinical features and may not derive benefit from maintenance rituximab, highlighting the need for further research in this area of need.

Non-maintenance intravesical Bacillus Calmette-Guérin induction therapy with eight doses in patients with high- or highest-risk non-muscle invasive bladder cancer: a retrospective non-randomized comparative study.

BACKGROUND: To explore possible solutions to overcome chronic Bacillus Calmette-Guérin (BCG) shortage affecting seriously the management of non-muscle invasive bladder cancer (NMIBC) in Europe and throughout the world, we investigated whether non-maintenance eight-dose induction BCG (iBCG) was comparable to six-dose iBCG plus maintenance BCG (mBCG). METHODS: This observational study evaluated 2669 patients with high- or highest-risk NMIBC who treated with iBCG with or without mBCG during 2000-2019. The patients were classified into five groups according to treatment pattern: 874 (33%) received non-maintenance six-dose iBCG (Group A), 405 (15%) received six-dose iBCG plus mBCG (Group B), 1189 (44%) received non-maintenance seven-/eight-dose iBCG (Group C), 60 (2.2%) received seven-/eight-dose iBCG plus mBCG, and 141 (5.3%) received only ≤5-dose iBCG. Recurrence-free survival (RFS), progression-free survival, and cancer-specific survival were estimated and compared using Kaplan-Meier analysis and the log-rank test, respectively. Propensity score-based one-to-one matching was performed using a multivariable logistic regression model based on covariates to obtain balanced groups. To eliminate possible immortal bias, 6-, 12-, 18-, and 24-month conditional landmark analyses of RFS were performed. RESULTS: RFS comparison confirmed that mBCG yielded significant benefit following six-dose iBCG (Group B) in recurrence risk reduction compared to iBCG alone (groups A and C) before (P < 0.001 and P = 0.0016, respectively) and after propensity score matching (P = 0.001 and P = 0.0074, respectively). Propensity score-matched sequential landmark analyses revealed no significant differences between groups B and C at 12, 18, and 24 months, whereas landmark analyses at 6 and 12 months showed a benefit of mBCG following six-dose iBCG compared to non-maintenance six-dose iBCG (P = 0.0055 and P = 0.032, respectively). There were no significant differences in the risks of progression and cancer-specific death in all comparisons of the matched cohorts. CONCLUSIONS: Although non-maintenance eight-dose iBCG was inferior to six-dose iBCG plus mBCG, the former might be an alternative remedy in the BCG shortage era. To overcome this challenge, further investigation is warranted to confirm the real clinical value of non-maintenance eight-dose iBCG.

Evaluation of ustekinumab trough levels during induction and maintenance therapy with regard to disease activity status in difficult to treat Crohn disease patients.

ABSTRACT: Ustekinumab (UST) is approved for the treatment of moderate and severe Crohn disease (CD). Therapeutic drug monitoring (TDM) can help monitor the therapeutic effects of biologics. Therefore, the aim of this study was to evaluate the clinical outcomes of UST-treated CD patients and to determine the UST trough level in clinical and corticosteroid-free remission.This retrospective study included patients with moderate and severe active disease (AD) treated intravenously with a weight-adapted induction dose of UST. The maintenance therapy consisted of 90 mg UST subcutaneously at week 8 and thereafter every 8 or 12 weeks, depending on the clinical response. Clinical and corticosteroid-free remission, Harvey-Bradshaw-Index (HBI), UST trough level, and further laboratory parameters were measured just before the injection of UST at each follow-up evaluation until week 40.37 CD patients with a median HBI of 9 at week 0 were included in the study. Starting from 24% at the beginning of the monitoring period, and 38% of patients at the end of the monitoring period were treated with an 8-week interval (P = .18). There was a significant improvement in clinical (P = .0004), corticosteroid-free remission (P = .03), and HBI (P < .0001) from week 0 until the end of the observation period. The serum UST trough level decreased significantly from 2.0 at week 8 to 0.3, in the maintenance therapy and 0.4 µg/ml at the end of the therapy (P < .0001). Neither UST trough level nor levels of C-reactive protein (CRP) or fecal calprotectin (FC) were associated with disease outcome. Concomitant immunomodulator therapy did not appear to affect the UST trough level or clinical course.UST is an effective treatment option for difficult-to-treat patients with CD. UST trough levels may not be associated with treatment efficacy or the prediction of treatment outcomes in patients with CD. Further prospective randomized trials should be conducted to evaluate whether UST trough levels are associated with treatment outcomes in patients with CD.

Outcomes for Patients With Acute Promyelocytic Leukemia in South Africa.

BACKGROUND: The characteristics and outcomes of patients with acute promyelocytic leukemia (APL) from sub-Saharan Africa have not been published. PATIENTS AND METHODS: We report retrospectively on consecutively diagnosed APL patients treated in Cape Town, South Africa, during 1998-2019. A total of 69 patients were treated, of whom 27 (39%) were classified as having high risk APL. RESULTS: Early death rates at 7 and 30 days were 7% and 13%, respectively, including 4 patients who died before any treatment could be administered. Overall survival at 3 years was 76.5% (95% confidence interval, 63.9-85.2) for the entire cohort, and 82.5% (95% confidence interval, 69.7-90.2) if patients who died within 7 days of diagnosis were excluded. For 13 patients (18.8%), there was a delay of 5 or more days from time of initial presentation at a peripheral hospital until arrival at the leukemia center and administration of all-trans retinoic acid; only 1 of these patients died within 30 days. CONCLUSION: Despite the challenges faced in the public healthcare system of a developing country, outcomes of APL patients treated at our center are similar to outcomes from developed countries.

Variation in immunosuppression practices among pediatric liver transplant centers-Society of Pediatric Liver Transplantation survey results.

BACKGROUND: Variation in IS exists among pediatric liver transplant centers. While individual centers may publish their practice paradigms, current data on practices as a whole are lacking. This study sought to ascertain the IS protocols of pediatric liver transplant centers within the SPLIT to better understand variability and similarities among peer institutions. METHODS: A 27-item questionnaire was developed within the SPLIT Quality Improvement and Clinical Care Committee. The survey collected data regarding center demographics, IS practices, and treatment of acute cellular rejection. RESULTS: Twenty-eight (64%) SPLIT centers responded with 22 (79%) centers performing more than 10 transplants per year and 17 (61%) following more than 100 post-transplant recipients. All centers use a written protocol, and 25 (89%) have a dedicated transplant pharmacist/PharmD. Twenty-five (89%) centers use steroids for induction alone or in combination with thymoglobulin/interleukin-2 antibodies. All centers use tacrolimus for initial maintenance therapy. Most centers have specialized protocols for ABO-incompatible transplants, recipients with renal dysfunction, autoimmune liver diseases, and liver tumors. Treatment of rejection varied but was associated with escalation in IS. CONCLUSION: IS practices among pediatric liver transplant centers are similar including the use of written protocols, pharmacy involvement, steroids for induction, tacrolimus as initial IS, tacrolimus reduction/delay for renal dysfunction, and escalation of IS with rejection severity. However, other IS practices show wide variability including treatment for ABO-incompatible grafts and presumed rejection. This study serves as a foundation to guide prospective research linking IS practice to outcomes to determine best practice.

Outcome and Prognostic Features in Pediatric Acute Megakaryoblastic Leukemia Without Down Syndrome: A Retrospective Study in China.

BACKGROUND: Acute megakaryoblastic leukemia (AMKL) is a biologically heterogeneous subtype of acute myeloid leukemia that originates from megakaryocytes. Patients with AMKL with non-Down syndrome (DS) had a poorer prognosis. However, clear prognostic indicators and treatment recommendations for this subgroup remain controversial. PATIENTS AND METHODS: Herein, we performed a retrospective study on 40 patients (age ≤ 18 years) with non-Down syndrome AMKL at our institution. We assessed the effect of different prognostic factors, such as their cytogenetic abnormalities, early treatment response, and the role of hematopoietic stem cell transplantation (HSCT) as post-remission treatment on the outcomes. RESULTS: The complete remission (CR) rate of the patients was 57.9% and 81.1%, respectively, at the end of induction therapy 1 and 2. The overall survival (OS) and event-free survival rates at 2 years were 41% ± 13% and 41% ± 10%, respectively. An analysis of the cytogenetic features showed that patients with +21 or hyperdiploid (> 50 chromosomes) had significantly better OS than those in other cytogenetic subgroups (Plog-rank = .048 and Plog-rank = .040, respectively). Besides cytogenetics, an excellent early treatment response (CR and minimal residual disease < 1% after induction therapy 1) also provided a significant survival benefit in univariate analysis in our study. However, multivariate analysis indicated that allogeneic HSCT was the only independent prognostic marker (relative risk, 11.192; 95% confidence interval, 2.045-61.241; P = .005 for OS and relative risk, 5.400; 95% confidence interval, 1.635-17.832; P = .006 for event-free survival, respectively). CONCLUSION: AMKL in patients with non-Down syndrome has a poor outcome. With poor OS but CR rates comparable with other acute myeloid leukemia subtypes, allogenic HSCT may be a better option for post-remission therapy than conventional chemotherapy, especially for those having a poor response to induction therapy.

The use of 5-aminosalicylate for patients with Crohn's disease in a prospective European inception cohort with 5 years follow-up - an Epi-IBD study.

BACKGROUND: The lack of scientific evidence regarding the effectiveness of 5-aminosalicylate in patients with Crohn's disease is in sharp contrast to its widespread use in clinical practice. AIMS: The aim of the study was to investigate the use of 5-aminosalicylate in patients with Crohn's disease as well as the disease course of a subgroup of patients who were treated with 5-aminosalicylate as maintenance monotherapy during the first year of disease. METHODS: In a European community-based inception cohort, 488 patients with Crohn's disease were followed from the time of their diagnosis. Information on clinical data, demographics, disease activity, medical therapy and rates of surgery, cancers and deaths was collected prospectively. Patient management was left to the discretion of the treating gastroenterologists. RESULTS: Overall, 292 (60%) patients with Crohn's disease received 5-aminosalicylate period during follow-up for a median duration of 28 months (interquartile range 6-60). Of these, 78 (16%) patients received 5-aminosalicylate monotherapy during the first year following diagnosis. Patients who received monotherapy with 5-aminosalicylate experienced a mild disease course with only nine (12%) who required hospitalization, surgery, or developed stricturing or penetrating disease, and most never needed more intensive therapy. The remaining 214 patients were treated with 5-aminosalicylate as the first maintenance drug although most eventually needed to step up to other treatments including immunomodulators (75 (35%)), biological therapy (49 (23%)) or surgery (38 (18%)). CONCLUSION: In this European community-based inception cohort of unselected Crohn's disease patients, 5-aminosalicylate was commonly used. A substantial group of these patients experienced a quiescent disease course without need of additional treatment during follow-up. Therefore, despite the controversy regarding the efficacy of 5-aminosalicylate in Crohn's disease, its use seems to result in a satisfying disease course for both patients and physicians.

Randomized phase III trial comparing switch-maintenance pemetrexed with observation followed by pemetrexed at progression in advanced NSCLC.

Objectives: Two phase III trials show that maintenance pemetrexed therapy after platinum-doublet chemotherapy prolongs overall survival (OS) and progression free survival (PFS) in advanced non-squamous non-small-cell lung cancer (NSCLC). However, few patients in the control arms received pemetrexed at progression in these trials, performance status (PS) two patients were ineligible and few of the participants were elderly. Thus, we designed this study comparing immediate switch-maintenance pemetrexed therapy with pemetrexed at progression after platinum-doublet chemotherapy.Methods: Patients with stage IIIB/IV non-squamous NSCLC, ≥18 years, PS 0-2, and non-progression after four courses of carboplatin/vinorelbine were randomized to receive immediate maintenance pemetrexed therapy or observation followed by pemetrexed at progression. The primary endpoint was OS, secondary endpoints were PFS, toxicity and health related quality of life (HRQoL).Results: 105 patients were randomized between May 2014 and September 2017. Median age was 67 years, 36% were >70 years, 9% had PS 2, 91% stage IV and 47% were women. In the observation arm, 73% received pemetrexed at progression. Patients in the maintenance arm had a numerically longer OS (median 12.0 vs. 10.0 months; p = .10) and a statistically significant longer PFS (median 3.1 vs. 1.9 months; p < .01). In multivariable analyses adjusting for baseline characteristics, there was a trend toward improved OS (HR 0.65, 95% CI 0.42-1.01); p = .05), and a significantly improved PFS (HR 0.53, 95% CI 0.35-0.80; p < .01). There were no significant differences in toxicity or HRQoL between the treatment arms.Conclusion: There was a trend toward prolonged OS and significantly longer PFS from switch- maintenance pemetrexed therapy when 73% of patients in the control arm received pemetrexed at progression. ClinicalTrials.gov Identifier: NCT02004184.

Adalimumab for maintenance of remission in Crohn's disease.

BACKGROUND: Conventional medications for Crohn's disease (CD) include anti-inflammatory drugs, immunosuppressants and corticosteroids. If an individual does not respond, or loses response to first-line treatments, then biologic therapies such as tumour necrosis factor-alpha (TNF-α) antagonists such as adalimumab are considered for treating CD. Maintenance of remission of CD is a clinically important goal, as disease relapse can negatively affect quality of life. OBJECTIVES: To assess the efficacy and safety of adalimumab for maintenance of remission in people with quiescent CD. SEARCH METHODS: We searched the Cochrane IBD Group Specialized Register, CENTRAL, MEDLINE, Embase, and clinicaltrials.gov from inception to April 2019. SELECTION CRITERIA: We considered for inclusion randomized controlled trials (RCTs) comparing adalimumab to placebo or to an active comparator. DATA COLLECTION AND ANALYSIS: We analyzed data on an intention-to-treat basis. We calculated risk ratios (RRs) and corresponding 95% confidence intervals (95% CI) for dichotomous outcomes. The primary outcome was failure to maintain clinical remission. We define clinical remission as a Crohn's Disease Activity Index (CDAI) score of < 150. Secondary outcomes were failure to maintain clinical response, endoscopic remission, endoscopic response, histological remission and adverse events (AEs). We assessed biases using the Cochrane 'Risk of bias' tool. We used GRADE to assess the overall certainty of evidence supporting the primary outcome. MAIN RESULTS: We included six RCTs (1158 participants). We rated four trials at low risk of bias and two trials at unclear risk of bias. All participants had moderate-to-severe CD that was in clinical remission. Four studies were placebo-controlled (1012 participants). Two studies (70 participants) compared adalimumab to active medication (azathioprine, mesalamine or 6-mercaptopurine) in participants who had an ileocolic resection prior to study enrolment. Adalimumab versus placebo Fifty-nine per cent (252/430) of participants treated with adalimumab failed to maintain clinical remission at 52 to 56 weeks, compared with 86% (217/253) of participants receiving placebo (RR 0.70, 95% CI 0.64 to 0.77; 3 studies, 683 participants; high-certainty evidence). Among those who received prior TNF-α antagonist therapy, 69% (129/186) of adalimumab participants failed to maintain clinical or endoscopic response at 52 to 56 weeks, compared with 93% (108/116) of participants who received placebo (RR 0.76, 95% CI 0.68 to 0.85; 2 studies, 302 participants; moderate-certainty evidence). Fifty-one per cent (192/374) of participants who received adalimumab failed to maintain clinical remission at 24 to 26 weeks, compared with 79% (149/188) of those who received placebo (RR 0.66, 95% CI 0.52 to 0.83; 2 studies, 554 participants; moderate-certainty evidence). Eighty-seven per cent (561/643) of participants who received adalimumab reported an AE compared with 85% (315/369) of participants who received placebo (RR 1.01, 95% CI 0.94 to 1.09; 4 studies, 1012 participants; high-certainty evidence). Serious adverse events were seen in 8% (52/643) of participants who received adalimumab and 14% (53/369) of participants who received placebo (RR 0.56, 95% CI 0.39 to 0.80; 4 studies, 1012 participants; moderate-certainty evidence) and withdrawal due to AEs was reported in 7% (45/643) of adalimumab participants compared to 13% (48/369) of placebo participants (RR 0.59, 95% CI 0.38 to 0.91; 4 studies, 1012 participants; moderate-certainty evidence). Commonly-reported AEs included CD aggravation, arthralgia, nasopharyngitis, urinary tract infections, headache, nausea, fatigue and abdominal pain. Adalimumab versus active comparators No studies reported failure to maintain clinical remission. One study reported on failure to maintain clinical response and endoscopic remission at 104 weeks in ileocolic resection participants who received either adalimumab, azathioprine or mesalamine as post-surgical maintenance therapy. Thirteen per cent (2/16) of adalimumab participants failed to maintain clinical response compared with 54% (19/35) of azathioprine or mesalamine participants (RR 0.23, 95% CI 0.06 to 0.87; 51 participants). Six per cent (1/16) of participants who received adalimumab failed to maintain endoscopic remission, compared with 57% (20/35) of participants who received azathioprine or mesalamine (RR 0.11, 95% CI 0.02 to 0.75; 51 participants; very low-certainty evidence). One study reported on failure to maintain endoscopic response at 24 weeks in ileocolic resection participants who received either adalimumab or 6-mercaptopurine (6-MP) as post-surgical maintenance therapy. Nine per cent (1/11) of adalimumab participants failed to maintain endoscopic remission compared with 50% (4/8) of 6-MP participants (RR 0.18, 95% CI 0.02 to 1.33; 19 participants). AUTHORS' CONCLUSIONS: Adalimumab is an effective therapy for maintenance of clinical remission in people with quiescent CD. Adalimumab is also effective in those who have previously been treated with TNF-α antagonists. The effect of adalimumab in the post-surgical setting is uncertain. More research is needed in people with recent bowel surgery for CD to better determine treatment plans following surgery. Future research should continue to explore factors that influence initial and subsequent biologic selection for people with moderate-to-severe CD. Studies comparing adalimumab to other active medications are needed, to help determine the optimal maintenance therapy for CD.

Treatment Pathways Leading to Biologic Therapies for Ulcerative Colitis and Crohn's Disease in the United States.

OBJECTIVES: Biologic therapies have been available for inflammatory bowel disease for >20 years, but patient outcomes have not changed appreciably over this time period. To better understand medication utilization for this disease, we evaluated a novel technique for visualizing treatment pathways, including initial treatment, switching, and combination therapies. METHODS: This retrospective, observational study used administrative claims data from the Truven Health MarketScan Commercial and Medicare Database. Adult patients with ≥2 consecutive health claims and newly diagnosed with ulcerative colitis (UC) or Crohn's disease (CD) were evaluated. Treatment pathways were visualized using Sankey diagrams representing the number of patients receiving treatment and duration of each treatment. RESULTS: In all, 28,119 patients with UC and 16,260 patients with CD were identified. The most common initial treatment for UC was 5-aminosalicylic acid monotherapy (61% of the patients), followed by corticosteroid monotherapy (25%); <1% of patients were initially treated with biologics. The most common initial treatment for CD was corticosteroid monotherapy (42%), followed by 5-aminosalicylic acid monotherapy (35%); <5% of the patients were initially treated with biologics. Significantly fewer patients followed biologic vs nonbiologic treatment pathways (UC: 6% vs 94%, CD: 19% vs 81%, both P < 0.05). DISCUSSION: Significantly fewer patients with inflammatory bowel disease followed treatment pathways that included biologic therapies compared with nonbiologic therapies, and very few patients were ever initiated on biologic therapy. Although we have made significant progress in treatment, our most effective medications are only being used in a small proportion of patients, suggesting barriers prevent optimized patient management.

Post-induction infliximab trough levels and disease activity in the clinical evolution of pediatric ulcerative colitis.

BACKGROUND AND AIMS: Recent adult evidence suggests that infliximab (IFX) trough levels (TL) in patients with severe ulcerative colitis (UC) may be decreased. The aims of our study were to compare post-induction IFX TL of children with severe versus moderate UC and to evaluate short- and long-term outcomes. METHODS: In this single-center retrospective study, children with a diagnosis of UC starting IFX with a Pediatric Ulcerative Colitis Activity Index (PUCAI) ≥35 and with available post-induction TL were recruited. UC characteristics, IFX dosage and interval, primary non-response, IFX failure, and surgery after 24 months were collected. Post induction TL, anti-IFX antibodies, and laboratory evaluations at the time of starting IFX were also acquired. RESULTS: A total of 90 children were enrolled, of whom 39 (43.3%) were classified as severe UC and 51 (56.6%) as moderate UC. Median post-induction IFX TL were lower in severe UC versus moderate group (5.5 vs 10.3; p = 0.03), despite a more frequently intensified IFX regimen. Children in the higher TL quartiles showed increased rates of clinical, biological, and combined remission (p = 0.04, p < 0.001, and p = 0.01, respectively). In a multivariate analysis, a PUCAI ≥65 and time interval from last IFX infusion were the only predictors associated with IFX TL. At 24 months, children in the higher TL quartiles had a decreased risk of IFX failure (p = 0.002). The severe UC group showed a higher risk of IFX failure at 24 months (16/23 (41%) vs. 11/40 (21.6%); p = 0.05). Kaplan-Meier methods demonstrated a trend toward statistical significance, with a two-year cumulative colectomy rate of 15.38% (95% confidence interval (CI) 8.1-15.6%) in children with severe UC and 3.92% (95% CI 2.9-10.8%) in patients with moderate UC (logrank test p = 0.06). CONCLUSIONS: Children starting IFX with severe UC showed lower post-induction TL and poor disease outcomes. Achieving adequate TL was associated with better efficacy outcomes.

Effectiveness and safety of Ustekinumab for the treatment of Crohn's disease in real-life experiences: a meta-analysis of observational studies.

Background: The aim of this meta-analysis was to estimate the effectiveness and safety of Ustekinumab in Crohn's disease (CD) reported by observational studies.Research design and methods: PubMed/Medline and Embase were systematically searched through September 2019. Only real-life observational studies were included.Results: Thirteen studies comprising 1450 patients met the inclusion criteria. Ustekinumab was administered subcutaneously at induction among 7 studies, while in 6 studies the intravenous formulation was used. At induction (8-16 weeks), the pooled estimate rates of clinical response and remission were 56% (95% CI: 43-68%; range: 16-94%; I2 = 94%) and 34% (95% CI: 25-45%; range: 15-58%; I2 = 90%), respectively. The rate of clinical response was higher among studies which employed the subcutaneous compared with the intravenous induction (68% vs. 38%, p = 0.01). At maintenance, the pooled estimate rates of clinical response, clinical remission, endoscopic response, and endoscopic remission were 62% (95% CI: 50-73%; range: 42-89%; I2 = 89%), 40% (95% CI: 28-54%; range: 26-73%; I2 = 90%), 56% (95% CI: 37-73%; range: 20-77%; I2 = 87%), and 19% (95% CI: 11-30%; range: 7-31%; I2 = 67%), respectively.Conclusions: Ustekinumab is an effective treatment in patients with CD with a reassuring safety profile. The subcutaneous induction seems to be superior to the intravenous one.

Withdrawal of low-dose prednisone in SLE patients with a clinically quiescent disease for more than 1 year: a randomised clinical trial.

OBJECTIVES: To compare the efficacy to prevent flares of maintenance versus withdrawal of 5 mg/day prednisone in systemic lupus erythematosus (SLE) patients with clinically quiescent disease. METHODS: A monocentric, 12-month, superiority, open-label, randomised (1:1) controlled trial was conducted with 61 patients continuing 5 mg/day prednisone and 63 stopping it. Eligibility criteria were SLE patients who, during the year preceding the inclusion, had a clinically inactive disease and a stable SLE treatment including 5 mg/day prednisone. The primary endpoint was the proportion of patient experiencing a flare defined with the SELENA-SLEDAI flare index (SFI) at 52 weeks. Secondary endpoints included time to flare, flare severity according to SFI and British Isles Lupus Assessment Group (BILAG) index and increase in the Systemic Lupus International Collaborating Clinics (SLICC) damage index (SDI). RESULTS: Proportion of patients experiencing a flare was significantly lower in the maintenance group as compared with the withdrawal group (4 patients vs 17; RR 0.2 (95% CI 0.1 to 0.7), p=0.003). Maintenance of 5 mg prednisone was superior with respect to time to first flare (HR 0.2; 95% CI 0.1 to 0.6, p=0.002), occurrence of mild/moderate flares using the SFI (3 patients vs 12; RR 0.2 (95% CI 0.1 to 0.8), p=0.012) and occurrence of moderate/severe flares using the BILAG index (1 patient vs 8; RR 0.1 (95% CI 0.1 to 0.9), p=0.013). SDI increase and adverse events were similar in the two treatment groups. Subgroup analyses of the primary endpoint by predefined baseline characteristics did not show evidence of a different clinical response. CONCLUSION: Maintenance of long term 5 mg prednisone in SLE patients with inactive disease prevents relapse. TRIAL REGISTRATION NUMBER: NCT02558517; Results.

Prevalence of endoscopic improvement and remission according to patient-reported outcomes in ulcerative colitis.

BACKGROUND: Treatment targets for ulcerative colitis are evolving towards achievement of endoscopic improvement and remission in addition to symptom resolution. It remains to be accurately quantified what proportion of patients with symptom resolution have residual endoscopic activity that might warrant treatment modification. AIM: To quantify the prevalence of endoscopic improvement and remission amongst ulcerative colitis patients with various permutations of patient-reported outcomes. METHODS: Individual participant data from active intervention and placebo arms of clinical trials of infliximab, golimumab, vedolizumab and tofacitinib were pooled to estimate the prevalence of endoscopic improvement (Mayo endoscopic sub-score [MES] 0 or 1) and remission (MES 0) scores with various permutations of the rectal bleeding sub-score (RBS) and stool frequency sub-score (SFS) of the Mayo score, following induction (6-8 weeks) and maintenance (30-54 weeks) therapy. Subgroup analyses were performed by year of publication and centrally read endoscopy scoring. RESULTS: Data from 2586 trial participants were analysed. Using locally scored endoscopy, the prevalence of endoscopic improvement and remission was highest among participants with a RBS 0 + SFS 0 post-induction (MES 0/1:81%, [95% CI 78-84]; MES 0:29% [26-33]) and during maintenance (MES 0/1:91% [87-93]; MES 0:57% [52-62]). Prevalence estimates were lower for more recently performed trials (P < .01). In comparison to locally scored endoscopy, when using central endoscopy scoring, the prevalence of endoscopic improvement and remission was lower post-induction (MES 0/1 57% [50-64], P < .001; MES 0 15% [11-21], P = .09) and during maintenance (MES 0/1 74% [67-81], P = .001; MES 0 31% [24-38], P = .001) for participants achieving a RBS 0 + SFS 0. CONCLUSIONS: Approximately 8 of 10 patients with normalisation of rectal bleeding and stool frequency have improvement in endoscopic disease activity, whereas approximately only half of these patients have endoscopic remission.

Nevirapine in HIV maintenance therapy - can "old drugs" survive in current HIV management?

AIMS OF THE STUDY: Nevirapine has an exceptional record for long-term tolerability with few side effects in human immunodeficiency virus (HIV) combined antiretroviral therapy (cART). Owing to relatively frequent hypersensitivity reactions (HSR) (15–25%) in the first 3 months after treatment initiation (especially in patients with a high CD4 count (>250/µl in women, >400/µl in men)), it is being used less and less. However, the rate of adverse events is lower when patients are already under suppressive cART. We present the results of a single centre strategy to offer the switch to a nevirapine-containing regimen and evaluate the potential role nevirapine could play in current antiretroviral treatment. METHODS: All adult HIV-positive patients starting nevirapine at our centre since 2010 were evaluated in this retrospective analysis. We examined the proportion of patients on cART containing nevirapine, as well as the number of starts and stops every 6 months. Nevirapine discontinuation rates were analysed by sex, age, hepatitis C virus (HCV) status, time on nevirapine, ethnicity, CD4 nadir as well as CD4 count, HIV-RNA and ART backbone at nevirapine start. RESULTS: Since 2014, more than a third of our treated HIV patients have been on nevirapine-containing therapy, with a stable percentage in the following years; 277 patients starting nevirapine for the first time were analysed. Thirty-three percent (92/277) of these first nevirapine therapies were discontinued, with 16 cases (17%) resuming nevirapine later during follow-up. Of the patients who continued nevirapine for more than 90 days (n = 221), 80% maintained nevirapine until their last follow-up. The nevirapine stop rate after the first 90 days was 15-fold lower (5.4 per 100 patient years, 95% confidence interval [CI] 4.0–7.2) than in the first 90 days. Overall, nevirapine was used for a median of 2.9 years (interquartile range [IQR] 0.5–5.6). In HCV co-infected patients, the treatment stop rate was 4-fold higher than in HIV mono-infected patients, but this difference was mainly due to treatment interruptions caused by drug-drug interactions with intermittent HCV therapy. Six out of seven Asian patients experienced HSR (hepatotoxicity / skin rash). In a population with 74% 3TC/ABC backbone, 81% fully suppressed, median CD4 nadir 240/µl (IQR 120–360) and median CD4 count at nevirapine start 590/µl (IQR 400–840), both high CD4 nadir and high CD4 count at nevirapine start were associated with lower rather than higher discontinuation rates. In fully suppressed patients with high CD4 count at nevirapine start, high CD4 nadir was not a risk factor for HSR. Major reasons for the discontinuation of nevirapine were HSR (liver, skin rash) in 38 cases (41% of all discontinuations) followed by other adverse drug reactions (n = 17) and non-adherence (n = 14). In patients who stopped nevirapine after more than 90 days, the major cause was non-adherence or other adverse drug reaction (both n = 12). CONCLUSIONS: In this study, two thirds of the patients continued nevirapine with favourable long-term tolerability and efficacy. Thus, this low-cost “old drug” may still represent a valid treatment switch option for maintenance therapy in selected patients with a fully suppressed viral load. However, further evaluation is needed.  .

Mycophenolate mofetil treatment in patients with autoimmune hepatitis failing standard therapy with prednisolone and azathioprine.

BACKGROUND: Data on rescue treatment of autoimmune hepatitis in patients that fail standard treatment are sparse. AIMS: To report our long-term experience with mycophenolate mofetil. METHODS: Retrospective study in 22 patients with autoimmune hepatitis who failed azathioprine and prednisolone due to adverse events (n = 14, 64%), lack of remission (n = 5, 23%) or a combination (n = 3, 13%). RESULTS: Mycophenolate mofetil was started at a dose of 20 mg/kg/day and increased to a maximum of 3 g/day. Follow-up was 0-6 months in 7 patients; more than 12 months in 15 (68%) and more than 24 months in 10. Normal aminotransferase levels were obtained (n = 3) or maintained (n = 7) in 10 patients (45%) after three to 30 weeks. 12 patients (55%) were withdrawn during the first 6 months, due to adverse events. Three patients were switched to cyclosporine and one underwent liver transplantation. Successful treatment with mycophenolate mofetil continued in 10 patients (45%) for a median of 71 months (range 20-124). Of these, one stopped prednisolone, five have a prednisolone dose <5 mg daily and four patients 5-10 mg. CONCLUSION: Approximately one of two patients with autoimmune hepatitis that fail standard treatment benefit from long-term maintenance with mycophenolate mofetil, especially those with previous intolerance to thiopurines, where mycophenolate mofetil is effective in two thirds.

Loss of response to scheduled infliximab therapy for Crohn's disease in adults: A systematic review and meta-analysis.

OBJECTIVE: To determine the potential predictors of loss of response (LOR) to infliximab (IFX) maintenance therapy for adult patients with Crohn's disease (CD). METHODS: We searched for English-language articles published between 1990 and March 2017 in PubMed, Embase, and the Cochrane Library. After identifying eligible studies, data extraction was performed independently by two reviewers. The potential prognostic variables were identified and dichotomized for meta-analysis. Based on the heterogeneity among study variables, random-effects models was used in our meta-analysis. RESULTS: Twenty-six studies met our eligibility criteria and consolidated drug response data were obtained from 3212 patients. The pooled rate of LOR to IFX maintenance therapy with a median follow-up of 1.1 years was 34%. The incidence of LOR to IFX therapy was increased in CD patients with perianal lesions (odds ratio [OR] 1.69, 95% confidence interval [CI] 1.04-2.75, P = 0.03), colon involvement (OR 2.56, 95% CI 1.20-5.50, P = 0.02) and younger age at CD onset (standardized mean difference -0.79, 95% CI -1.41 to -0.18, P = 0.01). CONCLUSIONS: The meta-analysis estimates the incidence of LOR among adult CD patients undergoing IFX therapy is 34%. The presence of perianal lesions, younger age at CD onset, and involvement of the colon are relative risk factors of LOR in CD patients received scheduled IFX maintenance therapy.

The association of antidepressant treatment with COPD maintenance medication use and adherence in a comorbid Medicare population: A longitudinal cohort study.

The effect of treating comorbid depression to achieve optimal management of chronic obstructive pulmonary disease (COPD) has not yet empirically tested. We examined the association between antidepressant treatment and use of and adherence to COPD maintenance medications among patients with new-onset COPD and comorbid depression. METHODS: Using 2006-2012 Medicare data, this retrospective cohort study identified patients with newly diagnosed COPD and new-onset major depression. Two exposures-antidepressant use (versus non-use) and adherence measured by proportion of days covered (PDC) (PDC ≥0.8 versus <0.8)-were assessed quarterly. We used marginal structural models to estimate the effects of prior antidepressant use and adherence on subsequent COPD maintenance inhaler use and adherence outcomes, accounting for time-varying confounders. RESULTS: A total of 25 458 COPD-depression patients, 82% with antidepressant treatment, were followed for a median of 2.5 years. Nearly half (48%) used at least 1 COPD maintenance inhaler in any given quarter; among users, 3 in 5 (61%) had a PDC of <0.8. Compared to patients with no antidepressant treatment, those with antidepressant use were more likely to use (relative ratio [RR] = 1.15, 95% confidence interval [CI] = 1.12- 1.17) and adhere to (RR = 1.08, 95% = 1.03-1.14) their COPD maintenance inhalers. Patients who adhered to antidepressant treatment were more likely to use and adhere to COPD maintenance inhalers. CONCLUSION: Regularly treated depression may increase use of and adherence to necessary maintenance medications for COPD. Antidepressant treatment may be a key determinant to improving medication-taking behaviors among COPD patients comorbid with depression.

Availability and Patterns of Intravesical BCG Instillations.

PURPOSE: Intravesical BCG instillations improve recurrence free survival in patients with non-muscle-invasive bladder cancer (NMIBC). METHODS: This is a national survey study, covering 223 urological centres, aimed at reliable identification of BCG availability and implemented treatment patterns. RESULTS: Response rate was 93.7%. BCG was used in 56.5% of urological departments. Another 22.7% referred patients to other hospitals for instillations, while 20.8% did not recommend BCG at all. The most common indications for BCG instillations were as follows: T1 tumours (88.5%), carcinoma in situ (83.6%) and high grade tumours (73.8%). Maintenance therapy was routinely abandoned in 16.4% of centres or was scheduled for <1 year, 1 year, 3 years and 1-3 years in 6.6%, 19.7%, 21.3% and 31.2% of centres, respectively. Continuation of BCGdespite treatment failure in carcinoma in situ cases was considered in 21.3% of departments. CONCLUSION: Our findings indicate that BCG is underused, while patterns of maintenance and follow-up are suboptimal.

Efficacy, Safety and Mucosal Healing of Methotrexate in a Large Longitudinal Cohort of Inflammatory Bowel Disease Patients.

BACKGROUND/AIMS: Evidence for the effectiveness of methotrexate (MTX) in treating inflammatory bowel disease (IBD) is still incomplete. This study assessed the effectiveness, safety and mucosal healing in IBD patients treated with MTX in the Swiss IBD Cohort. METHODS: Efficacy was defined by physician assessment or by CD activity index <150 points for Crohn's disease (CD) or Modified Truelove and Witts activity index <4 points for ulcerative colitis (UC), measured at least after 3 months of MTX therapy. Mucosal healing was evaluated after 3 months or more of therapy. RESULTS: MTX was administered to 341 patients (262 CD; 79 UC) out of 2,660 patients. MTX effectiveness was 59.5% (128/215) in CD and 40.0% (24/60) in UC (chi2 = 7.2409, p = 0.007). Among patients on MTX therapy at the time of analysis, remission was obtained in 87.4% (76/87) and 69.2% (9/13) for CD and UC patients respectively. The median duration of MTX therapy was 40 months for CD and 15 months for UC. Occurrence of adverse events was the first reason for treatment discontinuation (39.4% of all cases). The rate of mucosal healing with MTX was 9.5% for CD and 25% for UC patients respectively. CONCLUSION: MTX therapy was effective for the induction and maintenance therapy in IBD patients, with only a modest mucosal healing ability.
