RESUMO

Adverse nocebo responses can cause harm to patients and interfere with treatment adherence and effects in both clinic practice and clinical trials. Nocebo responses refer to negative outcomes to active medical treatments in clinical trials or practice that cannot be explained by the treatment's pharmacologic effects. Negative expectancies and nocebo effects are less known than placebo responses. Nocebo effects can be triggered by verbal suggestions, prior negative experiences, observation of others experiencing negative outcomes, and other contextual and environmental factors. As research advances over the years, mechanistic knowledge is accumulating on the neurobiological mechanisms of nocebo effects. This review summarizes studies on different facets of nocebo effects and responses and discusses clinical implications, ethical considerations, and future directions.

RESUMO

BACKGROUND: The dual inhibition of the BCR::ABL1 tyrosine kinase and BCL-2 could potentially deepen the response rates of chronic myeloid leukemia in chronic phase (CML-CP). This study evaluated the safety and efficacy of the combination of dasatinib and venetoclax. METHODS: In this phase 2 trial, patients with CML-CP or accelerated phase (clonal evolution) received dasatinib 50 mg/day for three courses; venetoclax was added in course 4 for 3 years. The initial venetoclax dose was 200 mg/day continuously but reduced later to 200 mg/day for 14 days, and to 100 mg/day for 7 days per course once a molecular response (MR)4.5 was achieved. After 3 years of combination, patients were maintained on single-agent dasatinib. The primary end point was the rate of major molecular response (MMR) by 12 months of combination. RESULTS: Sixty-five patients were treated. Their median age was 46 years (range, 23-73). By 12 months of combination, the MMR, MR4, and MR4.5 rates were 86%, 53%, and 45%, respectively. After a median follow-up of 42 months, the 4-year event-free and overall survival rates were 96% and 100%, respectively. Outcomes with the combination were comparable to historical outcomes with single-agent dasatinib (cumulative 12-months MMR rate of 79% with both strategies). The incidence of grade 3-4 neutropenia was 22% with the combination and 11% with single-agent dasatinib (p < .001). CONCLUSIONS: Treatment with dasatinib and venetoclax was safe and effective in CML-CP. The cumulative response rates with the combination were similar to those with single-agent dasatinib. Further follow-up is needed to evaluate the rates of durable deep molecular response and treatment-free remission.

RESUMO

BACKGROUND: Young female patients with chronic myeloid leukemia (CML) often face challenges becoming pregnant due to the teratogenicity of tyrosine kinase inhibitors (TKIs). METHODS: The authors conducted a nationwide survey of female patients with CML who experienced pregnancy between 2002 and 2020. RESULTS: Information for 70 pregnancies in 49 patients was obtained. There were three types of pregnancies: CML onset during pregnancy (n = 9), unplanned pregnancy mostly during treatment with a TKI (n = 25), and planned pregnancy during treatment-free remission (TFR) or treatment with interferon-alpha (IFN-α) (n = 36). The median duration from CML diagnosis to pregnancy in patients with planned pregnancy was significantly longer than that in patients with unplanned pregnancy (10.6 years vs. 4.1 years, p < .001). In 48 pregnancies that resulted in childbirth, TFR and treatment with IFN-α were chosen in 26 and 17 pregnancies, respectively. Sustained major or deeper molecular response was observed in 18 of 26 pregnancies with TFR. The patients who fulfilled the requirements for TKI therapy discontinuation by European LeukemiaNet recommendations achieved a TFR rate of 77% in pregnancy. Treatment with IFN-α might be effective for patients who are in complete cytogenetic response or deeper response (response rate, 76%). CONCLUSION: Pregnancy by TFR or treatment with IFN-α could be a safe and feasible way for patients with CML. However, a substantial duration of treatment with a TKI before conception may be needed for planned pregnancy. Planning and evaluation for pregnancy should be considered at the time of CML onset for female patients with childbearing potential.

RESUMO

BACKGROUND & AIMS: Currently, most patients with branch duct intraductal papillary mucinous neoplasms (BD-IPMN) are offered indefinite surveillance, resulting in health care costs with questionable benefits regarding cancer prevention. This study sought to identify patients in whom the risk of cancer is equivalent to an age-matched population, thereby justifying discontinuation of surveillance. METHODS: International multicenter study involving presumed BD-IPMN without worrisome features (WFs) or high-risk stigmata (HRS) at diagnosis who underwent surveillance. Clusters of individuals at risk for cancer development were defined according to cyst size and stability for at least 5 years, and age-matched controls were used for comparison using standardized incidence ratios (SIRs) for pancreatic cancer. RESULTS: Of 3844 patients with presumed BD-IPMN, 775 (20.2%) developed WFs and 68 (1.8%) HRS after a median surveillance of 53 (interquartile range 53) months. Some 164 patients (4.3%) underwent surgery. Of the overall cohort, 1617 patients (42%) remained stable without developing WFs or HRS for at least 5 years. In patients 75 years or older, the SIR was 1.12 (95% CI, 0.23-3.39), and in patients 65 years or older with stable lesions smaller than 15 mm in diameter after 5 years, the SIR was 0.95 (95% CI, 0.11-3.42). The all-cause mortality for patients who did not develop WFs or HRS for at least 5 years was 4.9% (n = 79), and the disease-specific mortality was 0.3% (n = 5). CONCLUSIONS: The risk of developing pancreatic malignancy in presumed BD-IPMN without WFs or HRS after 5 years of surveillance is comparable to that of the general population depending on cyst size and patient age. Surveillance discontinuation could be justified after 5 years of stability in patients older than 75 years with cysts <30 mm, and in patients 65 years or older who have cysts ≤15 mm.

RESUMO

BACKGROUND AND AIMS: Recommendations for stopping nucleoside analogue (NA) therapy in hepatitis B e antigen-negative chronic hepatitis B (CHB) are unclear. End-of-treatment quantitative hepatitis B serum antigen (EOTqHBsAg) thresholds <100 IU/mL or <1000 IU/mL have been proposed as stopping criteria, which we assessed by meta-analysis and meta-regression. METHODS: We searched PubMed, EMBASE, and conference abstracts for studies of hepatitis B e antigen-negative CHB NA discontinuation. Extracted studies were analyzed for risk of bias, pooled risk of hepatitis B serum antigen (HBsAg) loss, virological relapse (VR), and biochemical relapse (BR). Significant heterogeneity (I2) was addressed by subgroup analysis and random-effects meta-regression with known important covariates, including EOTqHBsAg thresholds, ethnicity, duration of therapy, and follow-up. RESULTS: We found 24 articles (3732 subjects); 16 had low and 8 had moderate risk of bias. The pooled risks of HBsAg loss, VR, and BR for stopping therapy at EOTqHBsAg <100 IU/mL were 41.8%, 33.4%, and 17.3%, respectively, vs 4.6%, 72.1%, and 34.6%, respectively, for EOTqHBsAg ≥100 IU/mL. The pooled risks of HBsAg loss, VR, and BR for stopping therapy at EOTqHBsAg <1000 IU/mL were 22.0%, 52.7%, and 15.9%, respectively, vs 3.4%, 63.8%, and 26.4%, respectively, for EOTqHBsAg ≥1000 IU/mL. Multivariable analysis for HBsAg loss showed that ethnicity, follow-up duration, and EOTqHBsAg <100 IU/mL and ≥100 IU/mL explained 85% of the variance in heterogeneity; Asians with EOTqHBsAg <100 IU/mL had 28.2%, while non-Asians with EOTqHBsAg <1000 IU/mL had 38.4% HBsAg loss. Multivariable analysis showed EOTqHBsAg <100 IU/mL and ≥100 IU/mL and other covariates only explained 43% and 63% of the variance in heterogeneity for VR and BR, respectively, suggesting that other factors are also important for relapse. CONCLUSIONS: While EOTqHBsAg thresholds, ethnicity, and follow-up duration strongly predict HBsAg loss, this is not true for VR and BR, hence stopping NA therapy should be considered cautiously.

RESUMO

BACKGROUND: In a princeps study we conducted in patients with advanced cutaneous squamous cell carcinoma treated with concomitant anti-Programmed cell death protein 1 (PD-1) and radiotherapy, we demonstrated a clinico radiological response to cemiplimab that appeared to persist over time, 1 year after treatment discontinuation. METHOD: We conducted a single-center descriptive study at Caen Hospital from September 1, 2021 to September 2023, in 14 patients with advanced carcinoma treated with cemiplimab until September 1, 2021. The aim of this update is to examine clinical and radiological follow-up 2 years after discontinuation of cemiplimab. RESULTS: Of the 12 patients with a partial or complete response, we report 8 (66.7%) persistent responses 2 years after stopping cemiplimab, with only 2 patients progressing to distant disease, one lost to follow-up, and one death a priori unrelated to the disease. CONCLUSION: Our study confirms a long-term and persistent effect despite discontinuation of cemiplimab at least up to 2 years later.

RESUMO

INTRODUCTION: Long-acting injectable cabotegravir + rilpivirine (CAB + RPV LAI) was approved for use in virally suppressed adults in the England and Wales national health service in November 2021. We describe a service evaluation of delivery processes and outcomes in 12 clinics. METHODS: Centres populated a database using information from local policies and clinical records. Services were asked to describe approval processes, clinic pathways, and adherence to national guidelines. Additional data were collected on reasons for regimen choice, treatment discontinuations, and management of viraemia. RESULTS: In total, 518 adults from 12 clinics were approved for CAB + RPV LAI between February 2022 and December 2023. Of the 518 people approved for CAB + RPV LAI, 423 received at least one injection. Median duration on CAB + RPV was 7.5 months (interquartile range 3.7-11.3). In total, 97% of injections were administered within the ±7-day window. Virological failure occurred in 0.7%, and 6% discontinued CAB + RPV. CONCLUSION: In this large UK-based cohort, robust approval processes and clinic protocols facilitated on-time injections and low rates of both discontinuation and virological failure.

RESUMO

To date, the effectiveness of direct-acting antivirals (DAAs) discontinued before 4 weeks has not been analysed in routine clinical practice. The study aimed to determine whether such a short therapy will enable achieving a sustained virological response under real-world experience. The study population of 97 patients who discontinued DAA therapy and had data enabling analysis of patient and disease characteristics, and assessment of treatment effectiveness was selected from 16,815 patients registered in the EpiTer-2 database. The most common reason for discontinuation was hepatic decompensation (20.6%) or the patient's personal decision (18.6%). Patients who discontinued treatment were significantly older, more frequently therapy-experienced, more likely to have cirrhosis, a history of decompensation and a Child-Pugh B or C classification than those who completed treatment. SVR was achieved by 93.5% of patients who discontinued treatment after 4 weeks, 60.9% if discontinued at 3 or 4 week and 33.3% at Week 1 or 2. Patients receiving pangenotypic but not genotype-specific treatment who discontinued after 4 weeks were as likely to achieve SVR as those who completed therapy. Patients who responded to treatment that lasted no longer than 2 weeks had a low baseline viral load (<400,000 IU/mL). Despite discontinuation of therapy after Week 4, the chances of SVR are high. Very early discontinuation does not preclude therapeutic success, especially in patients with low baseline viral load.

RESUMO

OBJECTIVES: The optimal duration of immunosuppressive (IS) treatment for lupus nephritis (LN) remains uncertain. We assessed the prevalence and predictors of IS tapering and discontinuation (D/C) in LN patients. METHODS: Data from 137 inception cohort LN patients were analyzed. We examined determinants of flares during tapering and after IS D/C, D/C achievement and time to D/C, and adverse long-term outcomes applying logistic and linear regression models. RESULTS: IS tapering was attempted in 111 (81%) patients, and D/C was achieved in 67.5%. Longer time to achieve complete renal response (CR) (OR : 1.07, p= 0.046) and higher SLEDAI-2K at tapering initiation (OR : 2.57, p= 0.008) were correlated with higher risk of renal flares during tapering. Persistent hydroxychloroquine use (≥2/3 of follow-up) (OR : 0.28, p= 0.08) and lower SLEDAI-2K 12 months before IS D/C (OR : 1.70, p= 0.013) decreased the risk of post-D/C flares. Adverse outcomes (>30% eGFR decline, chronic kidney disease, end-stage renal disease, death) at the end of follow-up (median124 months) were more frequent in patients with flares during IS tapering (53% vs 16%, p< 0.0038) but did not differ between IS D/C achievers and non-achievers. In proliferative LN, differences mirrored those in entire cohort, except for time to D/C, which occurred 20 months earlier in membranous vs proliferative LN (ß-coef=-19.8, p= 0.014). CONCLUSION: Earlier CR achievement and lower SLEDAI-2K at tapering initiation prevent flares during IS tapering, while persistent hydroxychloroquine use and lower SLEDAI-2K 12 months before IS D/C prevent post-D/C flares. Flares during tapering increase the risk of unfavorable long-term outcomes. Earlier IS D/C is feasible in membranous LN.

RESUMO

To test the hypothesis that during treatment with denosumab osteomorphs and precursors recycle to higher number of osteoclasts with time, we measured TRAcP5b in serum taken 6 months after the last injection in postmenopausal women treated for 1-10 years. Serum TRAcP5b values were not related to time of exposure to denosumab. PURPOSE: In women with postmenopausal osteoporosis the aetiology of the observed inverse relationship between duration of denosumab (Dmab) therapy and bone loss after its discontinuation is currently unknown. In studies in mice inhibition of RANKL is associated with an increase in osteomorphs and osteoclast precursors that recycle into osteoclasts and may accumulate with time. We hypothesized that longer inhibition of RANKL by Dmab will be followed by the synchronous formation of a larger number of osteoclasts after stopping treatment. To test this hypothesis, we measured serum TRAcP5b, a marker of osteoclast numbers, in postmenopausal women treated with Dmab for different periods of time up to 10 years. METHODS: TRAcP5b, C-terminal telopeptide of type 1 collagen (CTX) and procollagen type 1 N-terminal propeptide (P1NP) were measured at 6.0 months ± 15 days after last Dmab injection in 59 women who had received Dmab for 4.0 ± 2.3 years (range 1-10 years). Of these, 38 were treatment naïve (group 1) and 21 had received other treatments prior Dmab (group 2). RESULTS: Duration of Dmab treatment was not related to serum TRAcP5b values or to TRAcP5b/CTX ratio either in the whole cohort or in each of the two groups separately. In contrast, serum TRAcP5b values were significantly correlated with serum CTX values (rs = 0.619; p < 0.001), but not with serum P1NP values or BMD at all skeletal sites. CONCLUSION: Our observations indicate that serum TRAcP5b, measured at 6 months after a Dmab injection, is not a useful early marker for time-dependent increased accumulation of osteoclasts in humans and for identification of patients at risk for a higher rebound increase in bone resorption.

RESUMO

Increased fracture risk due to oral glucocorticoids (GCs) rapidly decreases with GC discontinuation. However, evidence for this is limited. We found that fracture risk decreased rapidly in the first year after GC discontinuation, while hip fracture risk remained higher than reference levels for about two years after GC discontinuation. PURPOSE: We investigated changes in fracture risk following discontinuation of long-term oral glucocorticoids (GCs) using Japan's nationwide health insurance claims database (NDBJ). METHODS: We identified patients aged ≥ 50 years who initiated GC therapy in 2012-2019. Those receiving ≥ 5 mg (prednisolone or equivalent, PSL)/day for ≥ 72 days in the initial 90 days of GC therapy were classified as the GC-exposure group, and those receiving < 5 mg PSL/day for < 30 days were classified as the reference group. Patients discontinuing GC after 90 days of GC therapy were classified as the GC-discontinuation group; all others were classified as the GC-continuation group. We tracked the incidence rates of hip and clinical vertebral fractures for up to 990 days, and assessed fracture risk after GC discontinuation by hazard ratios (HR) adjusted by inverse probability weighting using propensity scores for GC discontinuation. RESULTS: There was a total of 52,179 GC-discontinuation, 91,969 GC-continuation, and 43,138 reference group women, and 57,560, 93,736, and 33,696 men in the corresponding groups, respectively. According to adjusted HRs, incidence rates of fractures were significantly lower in the GC-discontinuation group than in the GC-continuation group in the initial 90 days after GC discontinuation and remained significant for 360 days, except for hip fracture in men. HRs for hip fractures remained significantly higher in the GC-discontinuation group compared to the reference group for 720 days post-discontinuation. CONCLUSION: Fracture risk declines rapidly in the first year after GC discontinuation, but vigilance is necessary as the increased risk persists for two years post-discontinuation.

RESUMO

BACKGROUND: Little is known about patients' experiences with benzodiazepine (BZD) discontinuation, which is thought to be challenging given the physiological and psychological dependence and accompanying potential for significant withdrawal symptoms. The marked decline in BZD prescribing over the past decade in the US Department of Veterans Affairs healthcare system presents an important opportunity to examine the experience of BZD discontinuation among long-term users. OBJECTIVE: Examine the experience of BZD discontinuation among individuals prescribed long-term BZD treatment to identify factors that contributed to successful discontinuation. DESIGN: Descriptive qualitative analysis of semi-structured interviews conducted between April and December of 2020. PARTICIPANTS: A total of 21 Veterans who had been prescribed long-term BZD pharmacotherapy (i.e., > 120 days of exposure in a 12-month period) and had their BZD discontinued. APPROACH: We conducted semi-structured interviews with Veteran participants to learn about their BZD use and the process of discontinuation, with interviews recorded and transcribed verbatim. Data were deductively and inductively coded and coded text entered into a matrix to identify factors that contributed to successful BZD discontinuation. KEY RESULTS: The mean age of interview participants was 63.0 years (standard deviation 3.9); 94.2% were male and 76.2% were white. Of 21 participants, only 1 had resumed BZD treatment (prescribed by a non-VA clinician). Three main factors influenced success with discontinuation: (1) participants' attitudes toward BZDs (e.g., risks of long-term use, perceived lack of efficacy, potential for dependence); (2) limited withdrawal symptoms; and (3) effective alternatives, either from their clinician (e.g., medication, psychotherapy) or identified by participants. CONCLUSIONS: BZD discontinuation after long-term use is relatively well tolerated, and participants appreciated reducing their medication exposure, particularly to one associated with physical dependence. These findings may help reduce both patient and clinician anxiety related to BZD discontinuation.

RESUMO

OBJECTIVE: This study explored the predictors of abemaciclib discontinuation, a cyclin-dependent kinase 4 and 6 inhibitor, in patients with breast cancer. MATERIAL AND METHODS: Between November 2018 and March 2023, 147 patients with breast cancer treated with abemaciclib at Osaka Medical and Pharmaceutical University Hospital and Kindai University Nara Hospital were included. The exclusion criteria were as follows: lack of blood testing within 2 weeks prior to starting abemaciclib therapy, transfer to another facility after the commencement of abemaciclib therapy, and discontinuation of abemaciclib therapy due to the diagnosis of another cancer. The duration from the initiation of abemaciclib to discontinuation for any reason and to temporary suspension or dose reduction due to adverse events were analyzed as outcome variables using multivariate Cox regression analysis. RESULTS: Baseline weight < 54 kg, bone metastases, and hemoglobin level ≤ 12.4 g/dL were independent predictors of abemaciclib discontinuation for any reason. The main adverse events leading to abemaciclib discontinuation were liver enzyme elevation and gastrointestinal symptoms. Additionally, focusing on the adverse event of abemaciclib, a baseline weight < 54 kg was an independent predictor of temporary suspension or dose reduction due to adverse events. The most common adverse events leading to temporary suspension or dose reduction were neutropenia and diarrhea. CONCLUSION: Patients with lower body weight are more susceptible to the adverse events of abemaciclib, increasing their risk of treatment discontinuation. In such patients, strict monitoring of adverse events and consideration of more frequent medical visits are necessary from the start of abemaciclib therapy.

RESUMO

BACKGROUND: Patients with irresectable stage III or metastatic melanoma presenting with poor prognostic factors are usually treated with a combination of immune checkpoint inhibitors (ICIs), consisting of ipilimumab and nivolumab. This combination therapy is associated with severe immune related adverse events (irAEs) in about 60% of patients. In current clinical practice, patients are usually treated with ICIs for up to two years or until disease progression or the occurrence of unacceptable AEs. The incidence of irAEs gradually increases with duration of treatment. While durable tumour responses have been observed after early discontinuation of treatment, no consensus has been reached on optimal treatment duration. The objective of the Safe Stop IPI-NIVO trial is to evaluate whether early discontinuation of ICIs is safe in patients with irresectable stage III or metastatic melanoma who are treated with combination therapy. METHODS: The Safe Stop IPI-NIVO trial is a nationwide, multicentre, prospective, single-arm, interventional study in the Netherlands. A total of 80 patients with irresectable stage III or metastatic melanoma who are treated with combination therapy of ipilimumab-nivolumab and have a complete or partial response (CR/PR) according to RECIST v1.1 will be included to early discontinue maintenance therapy with anti-PD-1. The primary endpoint is the rate of ongoing response at 12 months after start of ICI. Secondary endpoints include ongoing response at 24 months, disease control at different time points, melanoma specific and overall survival, the incidence of irAEs and health-related quality of life. DISCUSSION: From a medical, healthcare and economic perspective, overtreatment should be prevented and shorter treatment duration of ICIs is preferred. If early discontinuation of ICIs is safe for patients who are treated with the combination of ipilimumab-nivolumab, the treatment duration of nivolumab could be shortened in patients with a favourable tumour response.

RESUMO

BACKGROUND: Despite their documented efficacy, substantial proportions of patients discontinue antidepressant medication (ADM) without a doctor's recommendation. The current report integrates data on patient-reported reasons into an investigation of patterns and predictors of ADM discontinuation. METHODS: Face-to-face interviews with community samples from 13 countries (n = 30 697) in the World Mental Health (WMH) Surveys included n = 1890 respondents who used ADMs within the past 12 months. RESULTS: 10.9% of 12-month ADM users reported discontinuation-based on recommendation of the prescriber while 15.7% discontinued in the absence of prescriber recommendation. The main patient-reported reason for discontinuation was feeling better (46.6%), which was reported by a higher proportion of patients who discontinued within the first 2 weeks of treatment than later. Perceived ineffectiveness (18.5%), predisposing factors (e.g. fear of dependence) (20.0%), and enabling factors (e.g. inability to afford treatment cost) (5.0%) were much less commonly reported reasons. Discontinuation in the absence of prescriber recommendation was associated with low country income level, being employed, and having above average personal income. Age, prior history of psychotropic medication use, and being prescribed treatment from a psychiatrist rather than from a general medical practitioner, in comparison, were associated with a lower probability of this type of discontinuation. However, these predictors varied substantially depending on patient-reported reasons for discontinuation. CONCLUSION: Dropping out early is not necessarily negative with almost half of individuals noting they felt better. The study underscores the diverse reasons given for dropping out and the need to evaluate how and whether dropping out influences short- or long-term functioning.

RESUMO

BACKGROUND: The management of branch-duct type intraductal papillary mucinous neoplasms (BD-IPMN) varies in existing guidelines. This study investigated the optimal surveillance protocol and safe discontinuation of surveillance considering natural history in non-resected IPMN, by systematically reviewing the published literature. METHODS: This review was guided by PRISMA. Research questions were framed in PICO format "CQ1-1: Is size criteria helpful to determine surveillance period? CQ1-2: How often should surveillance be carried out? CQ1-3: When should surveillance be discontinued? CQ1-4: Is nomogram predicting malignancy useful during surveillance?". PubMed was searched from January-April 2022. RESULTS: The search generated 2373 citations. After screening, 83 articles were included. Among them, 33 studies were identified for CQ1-1, 19 for CQ1-2, 26 for CQ1-3 and 12 for CQ1-4. Cysts <1.5 or 2 cm without worrisome features (WF) were described as more indolent, and most studies advised an initial period of surveillance. The median growth rate of cysts <2 cm ranged from 0.23 to 0.6 mm/year. Patients with cysts <2 cm showing no morphological changes and no WF after 5-years of surveillance have minimal malignancy risk of 0-2%. Two nomograms created with over 1000 patients had AUCs of around 0.8 and appear to be feasible in a real-world practice. CONCLUSIONS: For patients with suspected BD-IPMN <2 cm and no other WF, less frequent surveillance is recommended. Surveillance may be discontinued for cysts that remain stable during 5-year surveillance, with consideration of patient condition and life expectancy. With this updated surveillance strategy, patients with non-worrisome BD-IPMN should expect more streamlined management and decreased healthcare utilization.

RESUMO

Multiple myeloma (MM) is an incurable hematological cancer requiring multiple lines of anti-myeloma regimens to promote disease remission and increase patient survival. The study assessed the incidence and reasons for discontinuation of first-line therapy in outpatients who started MM therapy in Belo Horizonte, Brazil from 2009 to 2020. A historical cohort study in which patients were followed from treatment initiation until discontinuation of first-line therapy. Discontinuation of first-line therapy was characterized as (i) discontinuation followed by a second-line therapy, and (ii) discontinuation that prevented patients from receiving a subsequent line of treatment. Non-parametric competing risk analysis with a 95% confidence interval estimated the cumulative incidences of discontinuation followed by a second-line therapy. The probability of discontinuation was compared according to selected variables using the Gray's test at a significance level of 5%. Approximately half of the participants (n = 260) were female and younger than 65 years. Discontinuation of first-line therapy followed by a second-line therapy accounted for 50.4% of the patients and occurred up to 30th month. The main reason for discontinuation not qualifying patients for receiving second-line therapy was to achieve a response to treatment. The maximum times for discontinuation not followed by a second-line therapy ranged from 12 to 20 months due to deaths or response to treatment. The probability of receiving second-line therapy was higher among patients initiating therapy in 2009-2014 and those not undergoing transplantation. In conclusion, discontinuation of first-line therapy followed by second-line treatment occurred as likely as the discontinuation not followed by a subsequent line.

RESUMO

BACKGROUND AND AIMS: Accurate biomarkers to predict outcomes following discontinuation of nucleos(t)ide analogue (NA) therapy are needed. We evaluated serum hepatitis B core-related antigen (HBcrAg) level as a biomarker for predicting outcomes after NA discontinuation. METHODS: Patients with HBeAg-negative chronic hepatitis B (CHB) without cirrhosis were enrolled in a prospective trial evaluating clinical outcomes until 96 weeks after NA discontinuation. End of treatment (EOT) and off-treatment levels of serum HBcrAg, HBsAg, HBV RNA and HBV DNA were used to predict key clinical outcomes including hepatitis flare (ALT ≥5 × ULN and HBV DNA > 2000 IU/mL). The SCALE-B score was calculated for the purposes of model validation. RESULTS: HBcrAg was tested amongst 65 participants. The median age was 54 years, 54% were male and 83% were Asian. HBcrAg was detectable in 86% patients. HBcrAg level ≥4 log U/mL at EOT was predictive of hepatitis flare [8/10 (80%) vs. 17/55 (31%), p = .001]. The presence of either HBcrAg ≥4 log U/mL or detectable HBV RNA at EOT predicted for both biochemical relapse and hepatitis flare. The SCALE-B model at EOT predicted for virological relapse, biochemical relapse, hepatitis flare and HBsAg loss in this cohort. An increase in the serum HBcrAg level off-treatment was also associated with hepatitis flare. No participant with EOT HBcrAg level ≥4 log U/mL achieved HBsAg loss. CONCLUSIONS: High levels of serum HBcrAg predict for hepatitis flare after stopping NA therapy and low likelihood of HBsAg loss at week 96. People with high levels of serum HBcrAg are not suitable candidates for NA discontinuation.

RESUMO

BACKGROUND: The US Food and Drug Administration-approved segesterone acetate and ethinyl estradiol ring-shaped contraceptive vaginal system, known as Annovera (Sever Pharma Solutions/QPharma, Malmö, Sweden), was inserted and removed under a woman's control for a 21 day in and 7 day out regimen for up to 13 cycles of use. OBJECTIVE: We aimed to describe the patterns of ring expulsion over time, to identify potential predictors of expulsion, and to evaluate the impact of expulsions on method discontinuation and pregnancy risk. STUDY DESIGN: Using data from 2064 participants who were enrolled in 2 multinational phase 3 clinical trials on the use of this contraceptive vaginal system, we examined data from participants' daily diaries for documentation of complete ring expulsion. We modeled the odds of reported expulsions over time with adjustment for background and demographic characteristics using mixed-effects logistic regression models with random intercepts. We compared the probability of continuation between those who did and those who did not report expulsions in the first cycle of use using survival analysis and hazards modeling. To determine if expulsions during the first cycle of use affected the risk for pregnancy, we calculated Pearl Indices. RESULTS: Most participants (75%) never experienced any expulsions during any cycle of use, and 91% to 97% did not experience an expulsion during any 1 cycle. The incidence of expulsion was highest in cycle 1 (9%). The odds of experiencing expulsions decreased by half in cycles 2 to 8 when compared with cycle 1 (0.48; 95% confidence interval, 0.40-0.58), and in cycles 9 to 13, expulsions were about a third of that in cycle 1 (0.32; 95% confidence interval, 0.26-0.41). Of those who did experience expulsions, most (62%-84%) experienced ≤2 expulsions per cycle. Participants from study sites in Latin America vs those in the United States had higher odds of not experiencing an expulsion (odds ratio, 1.95; 95% confidence interval, 1.45-2.63). Women with a higher education level had higher odds of experiencing an expulsion. Notably, parity, age, and body mass index were not associated with expulsion. Participants who experienced any expulsions in cycle 1 were more likely to discontinue use early (hazard ratio, 1.28; 95% confidence interval, 1.14-1.43) than participants who did not have an expulsion. The Pearl Index for participants who had expulsions during cycle 1 was 3.99 (95% confidence interval, 1.29-9.31), which was higher than that among participants who reported no expulsions (Pearl Index, 2.39; 95% confidence interval, 1.61-3.41), but the overlapping confidence intervals indicate that there is not sufficient evidence to demonstrate an association between expulsions and pregnancy risk. CONCLUSION: Expulsions were infrequent overall, decreased with subsequent cycles of use, and were not associated with body mass index or parity. Early discontinuation of product use was higher among participants who experienced an expulsion during cycle 1. Although it is unclear whether pregnancy risk was associated with expulsions, early recognition of expulsions among users may identify those at higher risk for discontinuation and may highlight when enhanced anticipatory counselling and guidance may be advantageous.

RESUMO

PURPOSE OF REVIEW: Despite the growing availability of oral PrEP, coverage remains suboptimal. Through the introduction of additional PrEP methods, including vaginal rings and long-acting injectable formulations, health systems globally are on the cusp of offering PrEP methods that vary by route of administration, efficacy, and frequency of use. With PrEP choice, it will be important to explore PrEP use patterns to better understand how the ability to choose and switch products affects coverage and continuation. In this review, we draw parallels with family planning (FP) by summarizing how method choice and product switching affected contraceptive coverage globally, synthesize what is known about PrEP product switching, and outline evidence gaps to help guide future research on PrEP switching in the context of choice. RECENT FINDINGS: Decades of research in FP has demonstrated that product switching is common and can lead to more satisfaction and increases in contraceptive use. While research on PrEP product switching is nascent, findings suggest switching is common, and that providing more than one PrEP option can increase coverage. Key evidence gaps include understanding product switching in the context of full versus constrained choice, switching in the context of temporary need, and developing interventions that promote product switching for those who could benefit. Providing choice and allowing people to start, stop, and switch products according to their needs and desires is a core component of a rights-based approach to HIV prevention. More research is needed to better understand what drives use patterns, including switching, and how to leverage choice to improve coverage. Standard definitions -some of which have been proposed in this review-are needed to inform comparable measurement. Finally, there is a need to holistically frame PrEP use to acknowledge changes in need over the life course, thus making method switching a standard part of HIV prevention.
