ABSTRACT

Abstract Tuberous sclerosis complex is an autosomal dominant disorder characterized by skin manifestations and formation of multiple tumors in different organs, mainly in the central nervous system. Tuberous sclerosis is caused by the mutation of one of two tumor suppressor genes, TSC1 or TSC2. Currently, the development of novel techniques and great advances in high-throughput genetic analysis made mutation screening of the TSC1 and TSC2 genes more widely available. Extensive studies of the TSC1 and TSC2 genes in patients with TSC worldwide have revealed a wide spectrum of mutations. Consequently, the discovery of the underlying genetic defects in TSC has furthered our understanding of this complex genetic disorder, and genotype-phenotype correlations are becoming possible, although there are still only a few clearly established correlations. This review focuses on the main symptoms and genetic alterations described in TSC patients from 13 countries in three continents, as well as on genotype-phenotype correlations established to date. The determination of genotype-phenotype correlations may contribute to the establishment of successful personalized treatment for TSC.

ABSTRACT

OBJECTIVE: To characterize a sample of Brazilian patients with maple syrup urine disease (MSUD) diagnosed between 1992 and 2011. METHODS: In this retrospective study, patients were identified through a national reference laboratory for the diagnosis of MSUD and through contact with other medical genetics services across Brazil. Data were collected by means of a chart review. RESULTS: Eighty-three patients from 75 families were enrolled in the study (median age, 3 years; interquartile range [IQR], 0.57-7). Median age at onset of symptoms was 10 days (IQR 5-30), whereas median age at diagnosis was 60 days (IQR 29-240, p = 0.001). Only three (3.6%) patients were diagnosed before the onset of clinical manifestations. A comparison between patients with (n = 12) and without (n = 71) an early diagnosis shows that early diagnosis is associated with the presence of positive family history and decreased prevalence of clinical manifestations at the time of diagnosis, but not with a better outcome. Overall, 98.8% of patients have some psychomotor or neurodevelopmental delay. CONCLUSION: In Brazil, patients with MSUD are usually diagnosed late and exhibit neurological involvement and poor survival even with early diagnosis. We suggest that specific public policies for diagnosis and treatment of MSUD should be developed and implemented in the country. .


OBJETIVO: Caracterizar uma amostra de pacientes brasileiros com a doença da urina de xarope de bordo (DXB) diagnosticados entre 1992 e 2011. MÉTODOS: Os pacientes foram identificados por meio de um laboratório de referência nacional para o diagnóstico de DXB e por meio do contato com outros serviços de genética médica no Brasil. Os dados foram coletados por meio de uma revisão de prontuários. RESULTADOS: Foram incluídos no estudo 83 pacientes de 75 famílias (idade média: três anos; intervalo interquartil (IQR): 0,57-7). A idade média no surgimento dos sintomas era de 10 dias (IQR: 5-30), ao passo que a idade média no diagnóstico era de 60 dias (IQR: 29-240; p = 0,001). Somente três (3,6%) pacientes foram diagnosticados antes do surgimento de manifestações clínicas. Uma comparação entre pacientes com (n = 12) e sem (n = 71) um diagnóstico precoce mostra que o diagnóstico precoce está associado à presença de histórico familiar positivo e à redução na prevalência de manifestações clínicas no momento do diagnóstico, porém sem melhor resultado. Em geral, 98,8% dos pacientes têm algum atraso no desenvolvimento psicomotor ou neurológico. CONCLUSÃO: No Brasil, os pacientes com DXB normalmente recebem um diagnóstico tardio e exibem um envolvimento neurológico e baixa sobrevivência, mesmo com um diagnóstico precoce. Sugerimos que políticas públicas específicas para o diagnóstico e tratamento da DXB sejam desenvolvidas e implementadas no país. .

ABSTRACT

Summary Introduction: cancer is the second leading cause of death in children between the ages of 0 and 14 years, corresponding to approximately 3% of all cases diagnosed in Brazil. A significant percentage (5-10%) of pediatric cancers are associated with hereditary cancer syndromes, including Li-Fraumeni/Li-Fraumeni-like syndromes (LFS/LFL), both of which are caused by TP53 germline mutations. Recent studies have shown that a specific TP53 mutation, known as p.R337H, is present in 1 in 300 newborns in Southern and Southeast Brazil. In addition, a significant percentage of children with LFS/LFL spectrum tumors in the region have a family history compatible with LFS/LFL. Objective: to review clinical relevant aspects of LFS/LFL by our multidisciplinary team with focus on pediatric cancer. Methods: the NCBI (PubMed) and SciELO databases were consulted using the keywords Li-Fraumeni syndrome, Li-Fraumeni-like syndrome and pediatric cancer; and all manuscripts published between 1990 and 2014 using these keywords were retrieved and reviewed. Conclusion: although LFS/LFL is considered a rare disease, it appears to be substantially more common in certain geographic regions. Recognition of population- specific risks for the syndrome is important for adequate management of hereditary cancer patients and families. In Southern and Southeastern Brazil, LFS/ LFL should be considered in the differential diagnosis of children with cancer, especially if within the spectrum of the syndrome. Due to the complexities of these syndromes, a multidisciplinary approach should be sought for the counseling, diagnosis and management of patients and families affected by these disorders. Pediatricians and pediatric oncologists in areas with high prevalence of hereditary cancer syndromes have a central role in the recognition and proper referral of patients and families to genetic cancer risk evaluation and management programs. .


Resumo Introdução: o câncer é a segunda principal causa de morte em crianças com idades entre 0 e 14 anos, correspondendo a cerca de 3% de todos os casos diagnosticados no Brasil. Um percentual significativo (5-10%) dos cânceres pediátricos são associados a síndromes hereditárias para câncer, incluindo Li-Fraumeni/Li-Fraumeni-like síndromes (LFS/LFL), causadas por mutações germinativas no gene TP53. Estudos recentes têm demonstrado que uma mutação específica em TP53, conhecida como p.R337H, está presente em 1 em 300 recém-nascidos no Sul e Sudeste do Brasil. Além disso, um percentual significativo de crianças com tumores do espectro LFS/LFL na região têm uma história familiar compatível com a síndrome. Objetivos: revisão dos aspectos clínicos relevantes da LFS/LFL por equipe multidisciplinar, com foco no câncer pediátrico. Métodos: o NCBI (PubMed) e SciELO foram consultados, usando as palavras-chave síndrome de Li-Fraumeni, síndrome de Li-Fraumeni-like e câncer pediátrico. Todos os artigos publicados entre 1990 e 2014 usando essas palavras- chave foram recuperados e revisados. Conclusão: apesar de LFS/LFL ser considerada uma doença rara, ela parece ser mais frequente em certas regiões. Reconhecer os critérios e condutas para identificação de pacientes em risco para LFS/LFL é fundamental para o manejo adequado dos pacientes com câncer hereditários e suas famílias. Devido à complexidade dessas síndromes, a abordagem multidisciplinar deve ser realizada. Pediatras e oncologistas pediátricos em áreas com alta prevalência de síndromes hereditárias de câncer têm um papel central no reconhecimento e encaminhamento adequado dos pacientes e famílias para programas de avaliação do risco de câncer genético e de gestão. .

ABSTRACT

OBJECTIVE: To assess the knowledge of nurses involved in the care of oncology patients in a public university hospital, regarding breast cancer and hereditary breast cancer, and to verify the use of such knowledge in their daily practice. METHODS: This is a descriptive cross-sectional study. Data were obtained through a structured, self-administered questionnaire. Out of 154 nurses, 137 (88.9%) agreed to participate in the study. Two questionnaires were excluded such that 135 questionnaires were analyzed. RESULTS: The global percentage of correct answers was not associated with age (p=0.173) or degree/specialization (p=0.815). Questions were classified into categories. In categories involving knowledge of established breast cancer risk factors and indicators of hereditary breast cancer, the rate of correct answers was 65.8% and 66.4%, respectively. On the practice of genetic counseling, 40.7% of those interviewed were not sure about the definition of genetic counseling and 78.5% reported never having identified or referred a patient at genetic risk for specialized risk assessment. Practice of educational actions regarding this subject was reported by 48.5% of those interviewed. CONCLUSION: This study reinforces the need to develop qualifying actions for nurses, so that strategies to control breast cancer become effective in their health care practice. .

ABSTRACT

Abstract Introduction: Phenylketonuria (PKU) is caused by the deficient activity of phenylalanine hydroxylase. Aim: To identify the factors associated with treatment adherence among patients with PKU seen at a southern Brazil reference center. Methodology: A cross-sectional, outpatient-based study including 56 patients with PKU (median age, 12 years) for whom a Phe-restrict diet plus specific metabolic formula have been prescribed. Patients were considered adherent or nonadherent depending on the median phenylalanine concentration for the 12 months prior to study and target levels of phenylalanine for each age range (<13 years = ≤360 µmol/L; ≥13 years = ≤900 µmol/L). Data were collected through a review of patient's medical records and a set of interviews with patients and their relatives. Results: Eighteen patients (32.1%; ≥13 years, 11) were classified as treatment adherent. Among all factors analyzed, only mental retardation, living with parents, and level of maternal education were associated with adherence to treatment. Conclusion: Our findings reinforce the importance of the family as promoting factor for treatment adherence.

ABSTRACT

Introdução: Fenilcetonúria (PKU) é um erro inato do metabolismo no qual ocorre um aumento dos níveis séricos do aminoácido fenilalanina. Objetivo: O presente estudo teve como objetivo avaliar a adesão ao tratamento de pacientes com PKU atendidos em um centro de referência do Rio Grande do Sul. Métodos: Estudo transversal de pacientes com PKU atendidos no ambulatório do Serviço de Genética Médica do Hospital de Clínicas de Porto Alegre, Brasil. Os parâmetros de adesão considerados foram a mediana de fenilalanina plasmática no último ano (critério 1); o consumo de fenilalanina (critério 2); o consumo de fórmula metabólica (critério 3); e o questionamento direto aos pacientes/familiares (critério 4). Resultados: Dos 45 pacientes incluídos no estudo, (mediana de idade de 11 anos), 51% eram do sexo masculino. De acordo com o critério utilizado, foram considerados aderentes 20 (critério 1); 16 (critério 2); 27 (critério 3) e 33 (critério 4) pacientes, respectivamente. Não houve concordância entre os critérios de adesão utilizados. Foram encontradas diferenças quando comparados os critérios 1 e 2 (P=0,027), critérios 1 e 3 (P=0,002) e critérios 3 e 4 (P=0,015). Conclusão: A adesão ao tratamento é dificilmente quantificada por parâmetros isolados. A distinta percepção por parte dos pacientes dá suporte à necessidade de busca de novas estratégias que promovam adesão, bem como do estudo de métodos que avaliem a mesma.


Introduction: Phenylketonuria (PKU) is an inborn error of metabolism in which there is an increase in the serum amino acid phenylalanine. Aim:This study aimed at evaluating the adherence to treatment of patients with PKU treated at a center of reference in Rio Grande do Sul. Methods: A cross-sectional study of PKU patients seen at the outpatient clinic of the Medical Genetics Service, Hospital de Clínicas de Porto Alegre, Brazil. The parameters considered for adherence were: median of plasma phenylalanine in the past year (criterion 1); consumption of phenylalanine (criterion 2); consumption of metabolic formula (criterion 3); and direct questioning of patients/families (criterion 4). Results: Of the 45 patients included in the study (median age of 11 years), 51% were male. According to the criteria used, the following number of patients were considered compliant: 20 (criterion 1); 16 (criterion 2); 27 (criterion 3); and 33 (criterion 4), respectively. There was no agreement among the adherence criteria used. Differences were found when comparing criteria 1 and 2 (P=0.027), criteria 1 and 3 (P=0.002), and criteria 3 and 4 (P=0.015). Conclusion: Adherence to treatment is barely quantified by isolated parameters. The patients’ different perception support the need of searching for new strategies to promote adherence and also new methods of assessment.

ABSTRACT

In 2004, a population-based cohort (the Núcleo Mama Porto Alegre - NMPOA Cohort) was started in Porto Alegre, southern Brazil and within that cohort, a hereditary breast cancer study was initiated, aiming to determine the prevalence of hereditary breast cancer phenotypes and evaluate acceptance of a genetic cancer risk assessment (GCRA) program. Women from that cohort who reported a positive family history of cancer were referred to GCRA. Of the 9218 women enrolled, 1286 (13.9 percent) reported a family history of cancer. Of the 902 women who attended GCRA, 55 (8 percent) had an estimated lifetime risk of breast cancer ³ 20 percent and 214 (23.7 percent) had pedigrees suggestive of a breast cancer predisposition syndrome; an unexpectedly high number of these fulfilled criteria for Li-Fraumeni-like syndrome (122 families, 66.7 percent). The overall prevalence of a hereditary breast cancer phenotype was 6.2 percent (95 percentCI: 5.67-6.65). These findings identified a problem of significant magnitude in the region and indicate that genetic cancer risk evaluation should be undertaken in a considerable proportion of the women from this community. The large proportion of women who attended GCRA (72.3 percent) indicates that the program was well-accepted by the community, regardless of the potential cultural, economic and social barriers.

ABSTRACT

PURPOSE: To report the clinical and neuroimaging, central nervous system (CNS) findings of patients with Fabry disease (FD) during 24 months of enzyme replacement therapy (ERT) with agalsidase-alpha. METHOD: Eight patients were included. Six completed 24 months of ERT. Clinical and magnetic resonance imaging (MRI) data were obtained at 0, 12 and 24 months of ERT. White matter lesions (WML) were evaluated as well as their relation to age, symptoms and neurological examination (CNS score). RESULTS: MRI was stable in 3 patients. WML and CNS score worsened in one patient, fluctuated in another, and improved in the sixth patient. In the whole series, there were 15 WML at baseline, and 19 at the 24th month. In two years, 4 lesions disappeared, whereas 8 appeared. CONCLUSION: A widespread pattern of silent WML in FD was seen. In two years, some WML appeared, and some disappeared. If these phenomena were related to the natural history, remains to be demonstrated.


OBJETIVO: Relatar os achados neurológicos e de imagem do sistema nervoso central (SNC), observados durante 24 meses de tratamento de reposição enzimática (ERT) com agalsidase-alfa, em pacientes com a doença de Fabry (FD). MÉTODO: 8 pacientes foram incluídos; 6 completaram 24 meses de ERT. Os dados foram obtidos aos 0, 12 e 24 meses de ERT. Lesões de substância branca (WML) foram avaliadas assim como sua relação com a idade e o exame neurológico (escore SNC). RESULTADOS: Os achados de ressonância nuclear magnética foram estáveis em 3 pacientes. As WML e o escore SNC pioraram em um caso; flutuaram em um outro caso; e melhoraram no sexto paciente. No todo, havia 15 WML antes da ERT e 19 WML depois de 24 meses de ERT. Em dois anos, 4 lesões desapareceram e 8 novas surgiram. CONCLUSÕES: Viu-se um padrão difuso de WML assintomáticas, na FD. Em dois anos, algumas WML surgiram, enquanto outras desapareceram. Resta demonstrar se esses fenômenos fazem parte da história natural da doença.

ABSTRACT

Fabry disease (FD) is an X-linked inborn error of glycosphingolipid metabolism due to thedeficiency of α-galactosidase A. The progressive accumulation of globotriaosylceramide (Gb3),particularly in the vascular endothelium, leads to renal, cardiac, and cerebrovascularmanifestations and early death. Clinical manifestations include the onset of pain and paresthesiasin extremities, angiokeratoma and hypohidrosis during childhood or adolescence. Proteinuriaand lymphedema occur with increasing age. Severe renal impairment leads to hypertension anduremia. Death usually occurs due to renal failure or cardiac or cerebrovascular disease. Diseasepresentation may be subtle, and its signs and symptoms are often discounted as malingering orare mistakenly attributed to other disorders, such as rheumatic fever, neurosis, multiple sclerosis,lupus, or petechiae.We present a 46-year-old man who since adolescence has suffered from painfulacroparesthesia, disseminated skin angiokeratomas, hypohidrosis and heat intolerance. He wassubmitted to a thorough investigation with different specialists, but never reached a diagnosis.He started hemodialysis 3 years ago and at the moment is in standby for kidney transplantation.He was enrolled in a Brazilian FD screening and a reduced serum activity of α-galactosidase A(0.0027 nmol/h/mL – reference value 4-22) confirmed the diagnosis of FD.He has angiokeratoma at the bottom area, his echocardiogram demonstrated left ventricularhypertrophy and the family history is very rich, as the patient has 15 siblings.


This case represents a very common story for FD patients. They usually spend most oftheir lives trying to find someone who could understand or explain their suffering. These resultsindicate that FD may be much more common among male dialysis patients than previouslyrecognized. Subsequently, FD should be considered in every patient with unexplained renaldisease, especially when cardiac or cerebral complications suggest an underlying multisystemicdisorder. Early diagnosis of FD is important because it allows family studies to identify otheraffected relatives for genetic counseling and therapeutic intervention.


A doença de Fabry (DF) é um erro inato do metabolismo dos glicoesfingolipídeos devido àdeficiência da α-galactosidase A. O acúmulo progressivo de globotriaosilceramida (Gb3), particularmente no endotélio vascular, leva a manifestações renais, cardíacas e cerebrovascularese morte precoce. As manifestações clínicas incluem o início, durante a infância ou adolescência,de episódios de dor e parestesias nas extremidades, angioqueratomas e hipohidrose. Com aidade, podem aparecer proteinúria e linfedema. Insuficiência renal grave leva à hipertensão euremia. O óbito ocorre devido à insuficiência renal ou doença cardíaca ou cerebrovascular. Aapresentação da doença pode ser sutil, e seus sinais e sintomas são erroneamente atribuídosa outras doenças, como febre reumática, neurose, esclerose múltipla, lúpus ou petéquias.Relatamos o caso de um paciente masculino com 46 anos que, desde a adolescência,sofre de acroparestesia, angioqueratomas disseminados, hipohidrose e intolerância ao calor.


Ele foi submetido a extensa investigação com diferentes especialistas, mas nunca chegou a umdiagnóstico. Iniciou hemodiálise há 3 anos e, no momento, está na lista de espera para transplantede rim. Participou de um programa brasileiro de triagem para DF, e uma atividade reduzida de α-galactosidase A (0,0027 nmol/h/mL – valor de referência 4-22) confirmou o diagnóstico de DF.O paciente apresenta angioqueratomas na área do calção, seu ecocardiograma demonstrahipertrofia ventricular esquerda e sua história familiar é rica, pois ele tem 15 irmãos.Este caso representa uma história muito comum entre pacientes com DF. Eles geralmentepassam a maior parte de suas vidas tentando encontrar alguém que compreenda ou expliqueseu sofrimento. Estes resultados indicam que a DF pode ser muito mais comum entre homensque realizam hemodiálise do que antes previsto. Subseqüentemente, a DF deve ser consideradaem todo paciente com doença renal sem causa aparente, principalmente quando complicaçõescardíacas ou cerebrovasculares sugerirem uma doença multissistêmica. O diagnóstico precoceda DF é importante, pois permite estudo familiar para identificar parentes afetados paraaconselhamento genético e intervenção terapêutica.
