RESUMO

Children and adolescents around the globe have mental health and neurodevelopmental needs. However, no country or region of the world has found good solutions to meet these needs, which are often long-term and complex. Most child and adolescent mental health research comes from high-income, mostly English-speaking, contexts even though 95% of the world's children and adolescents live in low- and middle-income countries (LMIC), where there is vast cultural, linguistic, and socio-economic diversity, with limited services and systems for child and adolescent mental health (CAMH). There is therefore both a 'knowledge gap' (more than 90% of all research represents less than 10% of the global population) and an 'identification and treatment gap' (fewer than 1 in 10 children in LMIC ever receive a diagnosis or any kind of treatment). The purpose of this editorial perspective was to consider the challenges of diversity, inclusion and equity in CAMH research around the globe, and to present some practical things we can all do to close these gaps and transform the global CAMH research agenda.

RESUMO

INTRODUCTION: Caregivers of children with autism face significant challenges in navigating health, education and other systems of care to ensure appropriate services for their children. In South Africa, for example, many children with autism are reported to be out of schools and waiting long periods for specialist school placements thus adding to the burden of care for caregivers and raising many questions about equity, diversity and inclusion. METHODS: Here we performed a qualitative study using focus groups to collect data on the perspectives of caregivers of children with autism waiting for school placement in the Western Cape Province of South Africa. We asked families about their experiences of current autism services and for suggestions to improve service delivery. RESULTS: The main theme that emerged was 'We wait and we wait'. Caregivers expressed high levels of frustration with existing autism educational and other services. Perspectives about services were captured under three categories. The first category, 'The costs of waiting' describes the socioemotional, financial and time costs associated with having a child with autism wait for educational services. The second category 'Barriers while waiting' describes the attitudinal, structural, process and communication barriers experienced by caregivers while seeking services for their children. The final category 'Expecting action' describes attitudinal, service and policy expectations that caregivers felt could improve service delivery. Caregivers provided 10 recommendations for autism service improvements. CONCLUSION: Caregivers of children with autism waiting for educational services in the Western Cape Province of South Africa expressed dissatisfaction with existing services. Efforts to find solutions to providing services and support to children with autism waiting for educational services and their caregivers should be prioritized.

RESUMO

Background: Despite a massive global increase in research on gender-diverse youth, there have been no studies in Africa on gender-diverse children and adolescents presenting to health services. Aim: This study aimed to present the first African findings of the demographic and mental health profile of youth who have presented at a gender service in South Africa. Setting: A specialist mental health outpatient service, consisting of psychiatry, psychology and nursing input, for gender-diverse child and adolescent patients in the Western Cape. Methods: All consenting youth seen at a gender service, consisting of psychiatry, psychology and nursing input, in state and by the same clinician in private practice between January 2012 and May 2019 were participants of a retrospective, sequential case series study. Data of interest, including gender identity and sexuality, mental health history and social information, were extracted from the psychiatry files of participants. Results: Thirty-nine participants were part of the registry and qualified for the study: 72% self-identified as white, 15% as coloured and 13% as black African. The rate of co-occurring psychopathology was high (64%) and included high rates of autism, particularly in trans males (26%), suicidal ideation in 31% and a history of suicide attempt(s) in 10%. Conclusions: This first study describing gender-diverse youth seeking support relating to their gender identity in Africa showed they had remarkable similarities to those studied internationally. Contribution: Establishing that transgender youth of all major racial groups in the province with similar demographic profiles to other parts of the world are presenting to services in South Africa and in need of mental health support and interventions.

RESUMO

BACKGROUND: Tuberous sclerosis complex (TSC) is a rare and complex genetic disorder, associated with tumor growth in various organ systems, epilepsy, and a range of neuropsychiatric manifestations including intellectual disability. With improving patient-centered care and targeted therapies, patient-reported outcome measures (PROMs) are needed to measure the impact of TSC manifestations on daily functioning. The aim of this study was to develop a TSC-specific PROM for adults that captures the impact of TSC on physical functions, mental functions, activity and participation, and the social support individuals with TSC receive, called the TSC-PROM. METHODS: COSMIN methodology was used to develop a self-reported and proxy-reported version. Development and validation consisted of the following studies: PROM development, content validity, structural validity, internal consistency, and construct validity. The International Classification of Functioning and Disability was used as a framework. Content validity was examined by a multidisciplinary expert group and cognitive interview study. Structural and construct validity, and internal consistency were examined in a large cohort, using confirmatory factor analysis, hypotheses testing, and Cronbach's alpha. RESULTS: The study resulted in an 82-item self version and 75-item proxy version of the TSC-PROM with four subscales (physical functions 18 and 19 items, mental functions 37 and 28 items, activities and participation 13 and 14 items, social support 13 items, for self version and proxy version respectively). Sufficient results were found for structural validity with sufficient unidimensionality for each subscale. With regard to construct validity, 82% of the hypotheses were met for the self version and 59% for the proxy version. The PROM showed good internal consistency (Cronbach's alpha 0.78-0.97). CONCLUSIONS: We developed a PROM for adults with TSC, named TSC-PROM, showing sufficient evidence for reliability and validity that can be used in clinical and research settings to systematically gain insight into their experiences. It is the first PROM in TSC that addresses the impact of specific TSC manifestations on functioning, providing a valuable, patient-centered addition to the current clinical outcomes.

RESUMO

This study aimed to examine the factor structure of the Strengths and Difficulties Questionnaire Self-Report version (SDQ-S), its psychometric properties and measurement invariance by gender and language spoken at home, among secondary school students in Western Cape, South Africa. A sample of 3,542 adolescents in Grade 8 (Mean age = 13.7 years) completed the SDQ-S in a three-language questionnaire (Afrikaans, English and isiXhosa). The data were collected from 42 secondary schools in Cape Town, South Africa. Confirmatory factor analyses with the WLSMV estimator with adjustment for cluster effects (schools) were applied. The SDQ-S was originally developed to cover five domains: four "difficulty" domains (hyperactivity/inattention, emotional, conduct, and peer) and one "strengths" domain (prosocial behavior). When the five factors were tested on the data for the current study, poor fit was obtained. After excluding four items, a three-factor solution with no cross-loadings and no correlated error terms obtained acceptable fit. The results are consistent with previous studies. Strong measurement invariance across genders and language spoken at home was confirmed. In studies of community samples, the use of the SDQ-S scale as an instrument with a three-factor dimension (internalizing, externalizing and prosocial) may be more appropriate than using the original five-factor model.

RESUMO

OBJECTIVE: Epilepsy is highly prevalent in patients with tuberous sclerosis complex (TSC). Everolimus showed higher efficacy than placebo for seizures in the primary analysis of the EXIST-3 study. Here, we present the long-term outcomes of everolimus at the end of the postextension phase (PEP; data cutoff date: October 25, 2017). METHODS: After completion of the extension phase, patients were invited to continue everolimus in the PEP with everolimus (targeted trough concentration = 5-15 ng/ml, investigator-judged). Efficacy assessments included changes in seizure status during the PEP collected at 12-week intervals as parent/caregiver-reported data through a structured questionnaire. RESULTS: Among 361 patients, 343 entered the extension phase and 249 entered the PEP. After 12 weeks in the PEP, 18.9% (46/244) of patients were seizure-free since the last visit of the extension phase and 64.8% (158/244) had a stable/improved seizure status. At 24 weeks, the corresponding percentages were 18.2% (42/231) and 64.5% (149/231). Among 244 patients, the response rate was 32.8% (80/244) during the 12-week maintenance period of the core phase and 63.9% (156/244) at the end of the extension phase. Of the 149 responders at the end of the extension phase, 70.5% were seizure-free or had stable/improved seizure status. Long-term efficacy data showed persistent responses were observed in 183 of 361 patients (50.7%); 63.9% of these patients had a response that lasted at least 48 weeks. The most frequent Grade 3-4 adverse events (≥2% incidence) reported throughout the study were pneumonia, status epilepticus, seizure, stomatitis, neutropenia, and gastroenteritis. Four patients died during the study. SIGNIFICANCE: The final analysis of EXIST-3 demonstrated the sustained efficacy of everolimus as adjunctive therapy in patients with TSC-associated treatment-refractory seizures, with a tolerable safety profile.

RESUMO

BACKGROUND: Condom use remains the most effective behavioural method for the prevention of HIV and unplanned pregnancies. However, condom use remains inconsistent among young people. Exploring the condom use decision-making processes that adolescents engage in might provide information that would assist in the prevention of many challenges related to poor sexual and reproductive health outcomes. This study therefore aimed to explore the factors that influenced decision-making about sexual debut and condom use of adolescents from two schools in the Western Cape, South Africa. METHODS: A sample of 16 adolescents were selected using purposive sampling. Data were collected using semi-structured, individual interviews. Thematic analysis was used to analyse the data generated. RESULTS: The link between sexual debut and affective processes was frequently discussed in condom use decision-making. Decisions about sexual debut were influenced by the belief that sex was a perceived symbol of 'true love' on the one hand, and respect for perceived parental expectations of age-appropriate sex, on the other. Condom use decision-making was shaped by adolescents' concerns about their future and lack of stability in their lives. Adolescents' fears of pregnancy, parenthood and disease shaped their condom use decision-making. It became evident that rational and affective decision-making in condom use choice were not mutually exclusive, but that these processes happened simultaneously. CONCLUSIONS: The study highlighted the role of affective states as part of the process of examining alternatives when deciding to use a condom or not. Interventions to strengthen condom use decision-making should therefore incorporate not only rational but also affective processes to improve adolescent sexual and reproductive outcomes.

RESUMO

BACKGROUND: Renal angiomyolipoma occurs at a high frequency in patients with tuberous sclerosis complex (TSC) and is associated with potentially life-threatening complications. Despite this frequency and severity, there are no large population-based cohort studies. Here we present baseline and follow-up data of the international TuberOus SClerosis registry to increase disease Awareness (TOSCA) with an aim to provide detailed clinical characteristics of renal angiomyolipoma among patients with TSC. METHODS: Patients of any age with a documented clinic visit for TSC within 12 months or who were newly diagnosed with TSC before participation in the registry were eligible. Data specific to renal angiomyolipoma included physical tumour characteristics (multiple, bilateral, lesion size and growing lesions), clinical signs and symptoms, and management. The effects of age, gender and genotype on the prevalence of renal angiomyolipoma were also evaluated. RESULTS: Renal angiomyolipoma was reported in 51.8% of patients at baseline, with higher frequency in female patients (57.8% versus 42.2%). The median age at diagnosis was 12 years. Prevalence of angiomyolipoma was higher in patients with TSC2 compared with TSC1 mutations (59.2% versus 33.3%, P < 0.01). Of the 1031 patients with angiomyolipoma at baseline, multiple lesions were reported in 88.4% and bilateral in 83.9% of patients, while the size of angiomyolipoma was >3 cm in 34.3% of patients. Most patients were asymptomatic (82%). Frequently reported angiomyolipoma-related symptoms included bleeding, pain, elevated blood pressure and impaired renal function. Embolization and mammalian target of rapamycin inhibitors were the two most common treatment modalities. CONCLUSIONS: The TOSCA registry highlights the burden of renal angiomyolipoma in patients with TSC and shows that renal manifestations are initially asymptomatic and are influenced by gender and genotype. Furthermore, the occurrence of significant problems from angiomyolipoma in a minority of younger patients suggests that surveillance should begin in infancy or at initial diagnosis.

RESUMO

Neuropsychiatric manifestations in Tuberous Sclerosis Complex (TSC): diagnostic guidelines, TAND concept and therapy with mTOR inhibitors Abstract. Tuberous sclerosis complex (TSC), albeit a rare autosomal-dominant multisystem disease with an incidence of 1:6,000, is one of the most important monogenetic disorders in child and adolescent psychiatry. In up to 90 % of patients, neurological disorders such as epilepsy and psychiatric disorders such as autism spectrum disorder, ADHD, affective disorders, and intellectual disability are observed. In recent years, significant progress has been made in understanding the molecular mechanism as well as in the clinical diagnosis and treatment of the disease. Here, we review these recent developments. In the first part, we describe the need for psychiatric assessment and treatment of patients and analyse challenges in interdisciplinary work between child and adolescent psychiatry, child neurology, and other professional groups. In the second part, we introduce the concept of TSC-associated neuropsychiatric disorders (TAND), developed by the TSC Neuropsychiatry Panel as a guide to help clinical teams, families, and individuals with TSC via screening, assessment, and treatment of neuropsychiatric symptoms and disorders as well as with a novel screening instrument, the TAND Checklist. Finally, we report findings from recent clinical trials of mTOR-inhibitors to treat TAND. The paper includes the German translation of the TAND Checklist as an electronic supplement.

RESUMO

Tuberous sclerosis complex (TSC) is associated with a wide range of behavioral, psychiatric, intellectual, academic, neuropsychological, and psychosocial difficulties, which are often underdiagnosed and undertreated. Here, we present a clinical update on TSC-associated neuropsychiatric disorders, abbreviated as "TAND," to guide screening, diagnosis, and treatment in practice. The review is aimed at clinical geneticists, genetic counselors, pediatricians, and all generalists involved in the assessment and treatment of children, adolescents and adults with TSC, and related disorders. The review starts with a summary of the construct and levels of TAND, before presenting up-to-date information about each level of investigation. The review concludes with a synopsis of current and future TAND research.

RESUMO

Attention-deficit/hyperactivity disorder (ADHD) is associated with significant impairments in social, educational, and occupational functioning, as well as specific strengths. Currently, there is no internationally accepted standard to assess the functioning of individuals with ADHD. WHO's International Classification of Functioning, Disability and Health-child and youth version (ICF) can serve as a conceptual basis for such a standard. The objective of this study is to develop a comprehensive, a common brief, and three age-appropriate brief ICF Core Sets for ADHD. Using a standardised methodology, four international preparatory studies generated 132 second-level ICF candidate categories that served as the basis for developing ADHD Core Sets. Using these categories and following an iterative consensus process, 20 ADHD experts from nine professional disciplines and representing all six WHO regions selected the most relevant categories to constitute the ADHD Core Sets. The consensus process resulted in 72 second-level ICF categories forming the comprehensive ICF Core Set-these represented 8 body functions, 35 activities and participation, and 29 environmental categories. A Common Brief Core Set that included 38 categories was also defined. Age-specific brief Core Sets included a 47 category preschool version for 0-5 years old, a 55 category school-age version for 6-16 years old, and a 52 category version for older adolescents and adults 17 years old and above. The ICF Core Sets for ADHD mark a milestone toward an internationally standardised functional assessment of ADHD across the lifespan, and across educational, administrative, clinical, and research settings.

RESUMO

This is the fourth and final study designed to develop International Classification of Functioning, Disability and Health (ICF, and children and youth version, ICF-CY) core sets for attention-deficit hyperactivity disorder (ADHD). To investigate aspects of functioning and environment of individuals with ADHD as documented by the ICF-CY in clinical practice settings. An international cross-sectional multi-centre study was applied, involving nine units from eight countries: Denmark, Germany, India, Italy, Portugal, Saudi Arabia, Sweden and Taiwan. Clinicians and clinical researchers rated the functioning level of 112 children, adolescents and adults with ADHD using the extended ICF-CY checklist version 2.1a. The ratings were based on a variety of information sources, such as medical records, medical history, clinical observations, clinical questionnaires, psychometric tests and structured interviews with participants and family members. In total, 113 ICF-CY categories were identified, of which 50 were related to the activities and participation, 33 to environmental factors and 30 to body functions. The clinical study also yielded strengths related to ADHD, which included temperament and personality functions and recreation and leisure. The study findings endorse the complex nature of ADHD, as evidenced by the many functional and contextual domains impacted in ADHD. ICF-CY based tools can serve as foundation for capturing various functional profiles and environmental facilitators and barriers. The international nature of the ICF-CY makes it possible to develop user-friendly tools that can be applied globally and in multiple settings, ranging from clinical services and policy-making to education and research.

RESUMO

We set out to examine key stakeholder perspectives on early detection and intervention for autism spectrum disorder (ASD) in South Africa. Early detection and intervention improves child and family outcomes and lessens long-term costs. We focused on stakeholders in the Western Cape province, one of the better-resourced in terms of healthcare. Eight senior management level stakeholders, two each from government's Health, Education, and Social Development, and the non-profit sector were identified using purposive sampling. In-depth interviews focused on key implementation- related themes. The National Integrated Early Childhood Development Policy was the most relevant to early detection and intervention. This policy, however, is not ASD specific. This lack of specificity is in keeping with an emerging theme: ASD was only seen within the context of other developmental disabilities, particularly by Health and Social Development. Specific ASD early detection and intervention may not currently align with Health and Social Development departmental goals. These departments are primarily responsible for identifying and providing services and financial support to young children with ASD. Increased ASD knowledge and local South African statistics on prevalence, burden and associated costs may alter this approach. At this time, ASD early intervention may be more closely aligned with Education department goals.

RESUMO

BACKGROUND: Everolimus, a mammalian target of rapamycin (mTOR) inhibitor, has been used for various benign tumours associated with tuberous sclerosis complex. We assessed the efficacy and safety of two trough exposure concentrations of everolimus, 3-7 ng/mL (low exposure) and 9-15 ng/mL (high exposure), compared with placebo as adjunctive therapy for treatment-resistant focal-onset seizures in tuberous sclerosis complex. METHODS: In this phase 3, randomised, double-blind, placebo-controlled study, eligible patients aged 2-65 years with tuberous sclerosis complex and treatment-resistant seizures (≥16 in an 8-week baseline phase) receiving one to three concomitant antiepileptic drugs were recruited from 99 centres across 25 countries. Participants were randomly assigned (1:1:1), via permuted-block randomisation (block size of six) implemented by Interactive Response Technology software, to receive placebo, low-exposure everolimus, or high-exposure everolimus. Randomisation was stratified by age subgroup (<6 years, 6 to <12 years, 12 to <18 years, and ≥18 years). Patients, investigators, site personnel, and the sponsor's study team were masked to treatment allocation. The starting dose of everolimus depended on age, body-surface area, and concomitant use of cytochrome 3A4/P-glycoprotein inducers. Dose adjustments were done to attain target trough ranges during a 6-week titration period, and as needed during a 12-week maintenance period of core phase. Patients or their caregivers recorded events in a seizure diary throughout the study. The primary endpoint was change from baseline in the frequency of seizures during the maintenance period, defined as response rate (the proportion of patients achieving ≥50% reduction in seizure frequency) and median percentage reduction in seizure frequency, in all randomised patients. This study is registered with ClinicalTrials.gov, number NCT01713946. FINDINGS: Between July 3, 2013, and May 29, 2015, 366 patients were enrolled and randomly assigned to placebo (n=119), low-exposure everolimus, (n=117), or high-exposure everolimus (n=130). The response rate was 15·1% with placebo (95% CI 9·2-22·8; 18 patients) compared with 28·2% for low-exposure everolimus (95% CI 20·3-37·3; 33 patients; p=0·0077) and 40·0% for high-exposure everolimus (95% CI 31·5-49·0; 52 patients; p<0·0001). The median percentage reduction in seizure frequency was 14·9% (95% CI 0·1-21·7) with placebo versus 29·3% with low-exposure everolimus (95% CI 18·8-41·9; p=0·0028) and 39·6% with high-exposure everolimus (95% CI 35·0-48·7; p<0·0001). Grade 3 or 4 adverse events occurred in 13 (11%) patients in the placebo group, 21 (18%) in the low-exposure group, and 31 (24%) in the high-exposure group. Serious adverse events were reported in three (3%) patients who received placebo, 16 (14%) who received low-exposure everolimus, and 18 (14%) who received high-exposure everolimus. Adverse events led to treatment discontinuation in two (2%) patients in the placebo group versus six (5%) in the low-exposure group and four (3%) in the high-exposure group. INTERPRETATION: Adjunctive everolimus treatment significantly reduced seizure frequency with a tolerable safety profile compared with placebo in patients with tuberous sclerosis complex and treatment-resistant seizures.

RESUMO

Epilepsy is a major risk factor for autism spectrum disorder (ASD) and complicates clinical manifestations and management of ASD significantly. Tuberous sclerosis complex (TSC), caused by TSC1 or TSC2 mutations, is one of the medical conditions most commonly associated with ASD and has become an important model to examine molecular pathways associated with ASD. Previous research showed reversal of autism-like social deficits in Tsc1 +/- and Tsc2 +/- mouse models by mammalian target of rapamycin (mTOR) inhibitors. However, at least 70 % of individuals with TSC also have epilepsy, known to complicate the severity and treatment responsiveness of the behavioural phenotype. No previous study has examined the impact of seizures on neurocognitive reversal by mTOR inhibitors. Adult Tsc2 +/- (Eker)-rats express social deficits similar to Tsc2 +/- mice, with additive social deficits from developmental status epilepticus (DSE). DSE was induced by intraperitoneal injection with kainic acid at post-natal days P7 and P14 (n = 12). The experimental group that modelled TSC pathology carried the Tsc2 +/- (Eker)-mutation and was challenged with DSE. The wild-type controls had not received DSE (n = 10). Four-month-old animals were analysed for social behaviour (T1), then treated three times during 1 week with 1 mg/kg everolimus and finally retested in the post-treatment behavioural analysis (T2). In the experimental group, both social interaction and social cognition were impaired at T1. After treatment at T2, behaviour in the experimental group was indistinguishable from controls. The mTOR inhibitor, everolimus, reversed social deficit behaviours in the Tsc2 haploinsufficiency plus DSE animal model to control levels.

RESUMO

This is the third in a series of four cross-cultural empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF, and Children and Youth version, ICF(-CY) Core Sets for Attention-Deficit Hyperactivity Disorder (ADHD). To explore the perspectives of individuals diagnosed with ADHD, self-advocates, immediate family members and professional caregivers on relevant areas of impairment and functional abilities typical for ADHD across the lifespan as operationalized by the ICF(-CY). A qualitative study using focus group discussions or semi-structured interviews of 76 participants, divided into 16 stakeholder groups. Participants from five countries (Brazil, India, Saudi Arabia, South Africa and Sweden) were included. A deductive qualitative content analysis was conducted to extract meaningful functioning and disability concepts from verbatim material. Extracted concepts were then linked to ICF(-CY) categories by independent researchers using a standardized linking procedure. In total, 82 ICF(-CY) categories were identified, of which 32 were related to activities and participation, 25 to environmental factors, 23 to body functions and 2 to body structures. Participants also provided opinions on experienced positive sides to ADHD. A high level of energy and drive, creativity, hyper-focus, agreeableness, empathy, and willingness to assist others were the most consistently reported strengths associated with ADHD. Stakeholder perspectives highlighted the need to appraise ADHD in a broader context, extending beyond diagnostic criteria into many areas of ability and disability as well as environmental facilitators and barriers. This qualitative study, along with three other studies (comprehensive scoping review, expert survey and clinical study), will provide the scientific basis to define ICF(-CY) Core Sets for ADHD, from which assessment tools can be derived for use in clinical and research setting, as well as in health care administration.

RESUMO

PURPOSE OF REVIEW: Most people with autism spectrum disorders (ASDs) live in low and middle-income countries, yet almost everything we know about ASD comes from high-income countries. Here we review recent research from Africa, with some references to research in other low-resource environments. We examine publications on screening and diagnosis, intervention, clinical presentation of ASD, cultural perspectives, and neuroscience and technology. RECENT FINDINGS: Open-access screening and diagnostic tools represent a positive, but nontrivial, future goal. Recent efforts at 'low intensity' community-based interventions are encouraging, but many significant scalability challenges remain. Proposals that ASD in Africa is more severe and overrepresented in high socioeconomic families are likely to be attributable to ascertainment biases and the absence of standardized phenotyping tools. Cultural perspectives and innovative use of technology and neuroscience have the potential to generate novel strategies of global relevance, but research priorities have to be determined by local needs. SUMMARY: To have a real impact on clinical services, training, and research in local communities, clinician-scientists should start by thinking globally. ASD research in Africa and other low-resource environments remains limited and of questionable quality and highlights the need to build high-quality research capacity in these low-resource environments.

RESUMO

BACKGROUND: Mammalian target of rapamycin (mTOR) inhibitors are recommended as first-line treatment of renal angiomyolipoma associated with tuberous sclerosis complex (TSC) or sporadic lymphangioleiomyomatosis (sporadic LAM), but follow-up is limited. Longer term efficacy and tolerability data from a Phase 3, double-blind, placebo-controlled trial are presented. METHODS: Following favorable results from the primary analysis (data cutoff 30 June 2011) of the EXIST-2 trial, patients still receiving study treatment were allowed to enter an open-label extension. Everolimus was initiated at 10 mg once daily and titrated based on tolerability. The primary outcome was angiomyolipoma response rate (≥ 50% reduction from baseline in target lesion volumes). Safety was a secondary endpoint. RESULTS: As of the cutoff date (1 May 2013), 112 patients had received everolimus, and the response rate in 107 patients with angiomyolipoma (median duration of medication exposure of 28.9 months) was 54%. The proportion of patients achieving angiomyolipoma reductions of ≥ 30% and ≥ 50% increased over time, reaching 81.6% (62/76) and 64.5% (49/76), respectively, by Week 96. No everolimus-treated patients experienced renal bleeding. The long-term safety profile was consistent with previous reports; adverse events (AEs) were mostly Grade 1/2, and there were no new safety issues. The frequency of emerging AEs and severe AEs lessened over time. CONCLUSIONS: Longer term everolimus treatment appeared safe and effective in patients with TSC- or sporadic LAM-associated renal angiomyolipoma not requiring surgical intervention. Continued reduction in angiomyolipoma volume was demonstrated, and there was no angiomyolipoma-related bleeding; AEs were predictable and generally manageable. TRIAL REGISTRATION: clinicaltrialsgov identifier: NCT00790400 (http://clinicaltrials.gov/ct2/show/NCT00790400).
