Uso de metformina y un inhibidor de SGLT2 en el manejo de lipodistrofia congénita generalizada. Reporte de caso / Use of metformin and an SGLT2 inhibitor to treat congenital generalized lipodystrophy. Case report

Resumen Introducción. La lipodistrofia congénita generalizada (LCG) es un síndrome genético autosómico recesivo extremadamente raro que se caracteriza por ausencia generalizada de tejido adiposo, deficiencia en la producción de hormonas como la leptina y complicaciones metabólicas potencialmente serias como diabetes mellitus tipo 2 (DM2), esteatohepatitis e hipertrigliceridemia. Presentación del caso. Paciente femenina de 17 años con un diagnóstico tardío de LCG y con diabetes mellitus (erróneamente clasificada como tipo I), hipertrigliceridemia severa e infecciones a repetición. Luego de introducir metformina y un inhibidor del SGLT2 en el manejo de la paciente, se logró un adecuado control metabólico. Conclusión. Con frecuencia, el desconocimiento de algunas enfermedades huérfanas lleva a diagnósticos erróneos y, por tanto, a tratamientos inadecuados que en algunos casos pueden empeorar la condición clínica de los pacientes. Por lo anterior, en el caso de la LCG, es necesario que la comunidad médica tenga una mejor comprensión de sus aspectos diagnósticos y terapéuticos para brindar un diagnóstico y tratamiento oportunos.

Abstract Introduction: Generalized congenital lipodystrophy (GDL) is an extremely rare autosomal recessive genetic syndrome characterized by generalized absence of adipose tissue, deficient production of hormones such as leptin, and potentially serious metabolic complications such as type 2 diabetes mellitus (DM2), steatohepatitis and hypertriglyceridemia. Case presentation: This is the case of a 17-year-old female patient with a late diagnosis of GDL and with diabetes mellitus (erroneously classified as type 1), severe hypertriglyceridemia and recurrent infections. Adequate metabolic control was achieved after the introduction of metformin and an SGLT2 inhibitor. Conclusion: Lack of knowledge about some orphan diseases usually leads to misdiagnosis and, therefore, to inadequate treatments that may worsen the clinical condition of patients. Therefore, in the case of GDL, the medical community should have a better understanding of its diagnostic and therapeutic aspects in order to provide timely diagnosis and treatment.

Targeted massively parallel sequencing for congenital generalized lipodystrophy

ABSTRACT Objective: Our aim is to establish genetic diagnosis of congenital generalized lipodystrophy (CGL) using targeted massively parallel sequencing (MPS), also known as next-generation sequencing (NGS). Subjects and methods: Nine unrelated individuals with a clinical diagnosis of CGL were recruited. We used a customized panel to capture genes related to genetic lipodystrophies. DNA libraries were generated, sequenced using the Illumina MiSeq, and bioinformatics analysis was performed. Results: An accurate genetic diagnosis was stated for all nine patients. Four had pathogenic variants in AGPAT2 and three in BSCL2. Three large homozygous deletions in AGPAT2 were identified by copy-number variant analysis. Conclusions: Although we have found allelic variants in only 2 genes related to CGL, the panel was able to identify different variants including deletions that would have been missed by Sanger sequencing. We believe that MPS is a valuable tool for the genetic diagnosis of multi-genes related diseases, including CGL.

Experiência de pessoas que vivem com a Síndrome de Berardinelli-Seip no Nordeste brasileiro / Experience of people living with the Berardinelli-Seip Syndrome in the Brazilian Northeast

Resumo O artigo analisa a experiência de pessoas que vivem com a Síndrome de Berardinelli-Seip no Nordeste brasileiro. Este estudo qualitativo foi desenvolvido com onze interlocutores, sendo nove pessoas vivendo com a síndrome e duas mães. Para coligir as informações, utilizaram-se observação participante, caracterização social e entrevistas semiestruturadas. Os dados foram analisados por meio da técnica de codificação temática. Emergiram duas categorias: (1) 'o segredo é fechar a boca': gerenciamento da alimentação na vida cotidiana; e (2) 'ah, é uma travesti?' Corpo, gênero e masculinização. Concluiu-se que na experiência dos interlocutores seus agenciamentos e criatividade se traduziram em estratégias para gerenciamento da alimentação que integravam gostos, valores, hábitos, prescrições biomédicas e prazeres envolvidos em situações de comensalidade. No que tange à corporeidade, evidenciou-se que as representações e as experiências com o corpo apresentam desigualdades de gênero, na medida em que a mulher passa a ser alvo privilegiado de estigmas, preconceitos e discriminação na vida adulta.

Abstract This paper analyzes the experience of people living with the Berardinelli-Seip Syndrome in the Brazilian Northeast. This qualitative study was developed with eleven informants, namely, nine people living with the syndrome and two mothers. Information was gathered using participant observation, social characterization and semi-structured interviews. Data were analyzed by means of a thematic coding technique. Two categories emerged: (1) 'the secret is to shut your mouth': food management in daily life; and (2) 'Ah, is it a transvestite?' body, gender, and masculinization. We concluded that, in the experience of the informants, their negotiations and creativity translated into strategies for food management that integrated tastes, values, habits, biomedical prescriptions and pleasures involved in commensality situations. Regarding corporeality, it has been shown that representations and experiences with the body show gender inequalities, insofar as women become privileged targets of stigmas, prejudices and discrimination in adult life.

Síndrome Berardinelli / Berardinelli syndrome

El síndrome Berardinelli es una enfermedad poco frecuente, con amplia heterogeneidad clínica y genética, clínicamente caracterizada por pérdida de tejido adiposo a nivel subcutáneo y de otros tejidos. Esta lipodistrofia generalizada congénita provoca hipertrofia muscular, asociada a trastornos endocrinos, con crecimiento acelerado durante la infancia, pubertad precoz e hiperglicemia. Está considerada una enfermedad metabólica rara, que se hereda de forma autosómico recesiva. En la actualidad se describen 4 variantes de este síndrome, con varios genes implicados. El objetivo de este trabajo es describir las características clínicas en una niña, en la cual su aspecto fenotípico recuerda este síndrome, por la lipodistrofia marcada y aumento de la musculatura desde la etapa de lactante, por lo cual se consideró necesaria la valoración en equipo multidisciplinario para su adecuado seguimiento y asesoramiento genético a sus familiares(AU)

Berardinelli syndrome is a rare disease, with broad clinical and genetic heterogeneity, and clinically characterized by loss of fatty tissue at subcutaneous level and of other tissues. This generalized congenital lipodystrophy causes muscle hypertrophy associated to endocrine disorders, accelerated growth at childhood, early puberty and hyperglycemia. It is considered as a rare metabolic disease and also recessive autosomal inheritance. Nowadays, four variants of the syndrome are described in which several gens are involved. The objective of this paper was to describe the clinical characteristics of a girl whose phenotypical aspect resembles this syndrome due to the marked lipodystrophy and increased musculature since her breastfeeding phase. Therefore, it was necessary to make an assessment by a multidisciplinary team for her adequate follow-up and the genetic counselling to her family(AU)

Síndrome de berardinelli-seip e condição de saúde oral: relato de série de casos / Berardinelli-Seip syndrome and oral health status: case series

Introdução: A lipodistrofia generalizada congênita, também conhecida como Síndrome de Berardinelli-Seip (SBS), é uma condição autossômica recessiva rara caracterizada pela ausência quase total de tecido adiposo subcutâneo desde o nascimento. As características metabólicas, fisiológicas, bioquímicas e genéticas da SBS são amplamente divulgadas entre a comunidade científica. No entanto, existem poucos estudos sobre as possíveis condições bucais associadas a esta síndrome. Objetivo: Avaliar a condição de saúde bucal de um grupo de indivíduos portadores da Síndrome de Berardinelli-Seip e identificar a ocorrência de possíveis alterações orais, relacionadas ou não à condição sistêmica. Métodos: Avaliação da condição de cárie e necessidade de tratamento, grau de edentulismo e condição de saúde periodontal, por meio de métodos preconizados pelo Projeto SBBrasil 2010, aplicado a nível nacional, em 33 pessoas diagnosticadas com SBS em um estado brasileiro. Resultados: o CPOD médio encontrado foi de 16,7. A média de dentes cariados correspondeu a um valor de 4,9 e a média do número de dentes perdidos correspondeu a 6,4. A condição periodontal revelou presença de sangramento gengival em 61% dos sítios avaliados, cálculo dentário em 35% e bolsa rasa em 6 sítios dos 54 avaliados no total. Conclusões: alta prevalência de sangramento gengival, refletindo uma condição de gengivite entre os participantes, afirmada também pela ausência de casos avançados de periodontite. Além disso, foi verificado um alto CPO-D e baixo grau de edentulismo (AU).

Background: Congenital Generalized Lipodystrophy, also known as Berardinelli-Seip syndrome (SBS), is a rare, autosomal recessive disease characterized by the nearly complete absence of subcutaneous adipose tissue beginning at birth. The metabolic, physiologic, biochemical and genetic characteristics of SBS are widely divulged among the scientific community. However, there are few studies on the possible oral conditions associated with this syndrome. Objective: the aim of the present study was to assess oral health status in a group of individuals with SBS and identify the occurrence of possible oral conditions. Methods: Evaluation of dental caries, treatment needs, degree of edentulism and periodontal health status using the methods recommended by the 2010 Oral Health Brazil project, in 10 people diagnosed with SBS in a Brazilian state. Results: The mean DMFT index was 16.7. The mean number of decayed teeth was 4.9. The mean number of missing teeth was 6.4. Regarding periodontal status, gingival bleeding was found in 61% of the sites examined, dental calculus was found in 35% and shallow pockets were found in six of the 54 sites evaluated. Conclusions: The prevalence of gingival bleeding was high, demonstrating gingivitis among the participants. Was an absence of cases with advanced periodontal disease. The participants had a low degree of edentulism, but high DMFT index values (AU).

Lipodistrofia congénita generalizada en un paciente con anomalía de Dandy Walker / Congenital generalized lipodystrophy in pacient with Dandy Walker anomaly

La asociación entre la lipodistrofia congénita generalizada y la anomalía de Dandy Walker no es habitual. Se reporta el caso de una niña de 1 año de edad que ingresa al hospital a los 4 meses por riesgo social, con diagnóstico de anomalía de Dandy Walker. Durante su internación, se evidencia en forma progresiva aspecto acromegaloide, facies triangular, hirsutismo, lipoatrofia, hipertrofia muscular, clitoromegalia, distensión abdominal con hepatomegalia progresiva e hpertrigliceridernia. Se arriba así al diagnóstico clínico de lipodistrofia congénita generalizada. Se revisan los aspectos clínicos y el seguimiento interdisciplinario para la detección oportuna de insulinorresistencia y diabetes, pubertad precoz, miocardiopatía, entre otras. Respecto de la anomalía de Dandy Walker, se realizan controles evolutivos en búsqueda de la aparición de signos de hipertensión endocraneana. Por el carácter autosómico recesivo de la lipodistrofia congénita generalizada, es importante realizar el asesoramiento genético a los padres.

The objective of this study is to describe the unexpected association between the congenital generalized lipodystrophy (CGL) and Dandy Walker anomaly. We report the case of a 1-year-old infant who was hospitalized at her fourth month of life with Dandy Walker anomaly diagnosis and an increased social risk. During her hospitalization, she developed progressively: acromegaloid aspect, triangular fascia, hirsutism, lipoatrophy, muscle hypertrophy, clitoromegaly, abdominal distention, progressive hepatomegaly, and hypertriglyceridemia. This led to the clinical diagnosis of congenital generalized lipodystrophy. Importance shouldbe given to the examination of clinical aspects as well as the interdisciplinary follow-up for proper detection of insulin resistance and diabetes, early puberty, cardiomyopathy, among others. In case of Dandy Walker anomaly, it should be checked the evolution to search intracranial hypertension signs. Due to its autosomal recessive nature, it is important to provide genetic counseling to the parents.

Do you know this syndrome? / Voce conhece esta sindrome?

Berardinelli-Seip syndrome is a rare autosomal recessive disease characterized by inadequate metabolism and inefficient storing of lipids in fat cells, generating accumulation of fat in organs such as the liver, spleen, pancreas, heart, arterial endothelium and skin. Classically, patients manifest generalized lipoatrophy at birth or until 2 years of age, and in adolescence usually develop marked insulin resistance with rapid progression to diabetes and dyslipidemia. We report the case of a 17-year-old Berardinelli-Seip syndrome patient with eruptive xanthoma associated with severe hypertriglyceridemia. It is worth noting Eruptive xanthoma as a dermatological manifestation that is not generally highlighted in the reports of cases of this genetic metabolic disorder.

Síndrome de Berardinelli-Seip é doença genética autossômica recessiva rara, caracterizada por ineficiência em metabolizar e estocar material lipídico adequadamente nos adipócitos, gerando acúmulo de gordura em órgãos não habituais, como fígado, baço, pâncreas, coração, endotélio arterial e pele. Classicamente, os portadores nascem ou manifestam lipoatrofia generalizada até os 2 anos e, geralmente na adolescência, desenvolvem marcada resistência insulínica com rápida progressão para diabetes e dislipidemia. Relatamos um caso de portadora da síndrome de Berardinelli-Seip, de 17 anos, com xantoma eruptivo associado à hipertrigliceridemia grave. Ressalta-se o xantoma eruptivo como manifestação dermatológica não enfatizada nos casos relatados sobre esse distúrbio metabólico genético.

Abstract: Berardinelli-Seip congenital lipodystrophy is a rare metabolic disorder characterized bysevere generalized lipodystrophy, insulin resistance, and dyslipedemia. The condition is associatedwith various dermatological and systemic manifestations. Complications include hypertrophiccardiomyopathy, a fatty liver with hepatic dysfunction, muscular hypetrophy, and various endocrinedisturbances. We report a case of this form of lipodystrophy in an 18-year-old female who wasadmitted with hyperglycaemia without evidence of ketoacidosis or hyperglycemic hyperosmolarstate, with hepatomegaly, signs of insulin resistance and absence of adipose tissue. After furtherinvestigation, a diagnosis of Berardinelli-Seip syndrome was made. Early recognition of congenitallipodystrophy is essential to prevent complications, and allows genetic and reproductive counselingto patients and their families. A brief review of the literature is also included.

Congenital generalized lipodystrophy of Berardinelli-Seip type: A rare case.

Congenital generalized lipodystrophy of Berardinelli-Seip type is a rare autosomal recessive disorder characterized by nearly complete absence of adipose tissue and a consequent generalized muscular appearance, which is recognized easily at birth. The condition is associated with various dermatological and systemic manifestations. We report a case of this form of lipodystrophy. The patient had several cutaneous manifestations, including severe acanthosis nigricans, generalized hyperpigmentation, curly scalp hair, prominent subcutaneous veins, and enlarged clitoris. She also had associated celiac disease.

Síndrome de Berardinelli-Seip: descrição genética e metabólica de cinco pacientes / Genetic and metabolic description of five patients with Berardinelli-Seip syndrome

OBJETIVO: Descrever o perfil genético e metabólico de portadores da síndrome de Berardinelli-Seip (BSCL) acompanhados no Instituto da Criança do HC-FMUSP. SUJEITOS E MÉTODOS: Pacientes com as características clínicas da BSCL (n = 5), todas do sexo feminino, foram avaliadas com dosagens de glicose e insulina, lípides, leptina, enzimas hepáticas, análise de DNA, ultrassonografia abdominal. RESULTADOS: A deficiência de leptina e a hipertrigliceridemia foram constatadas nas cinco pacientes. Três evoluíram para diabetes melito (DM). Quatro tiveram mutação no gene AGPAT2 e uma no gene CAV1. CONCLUSÃO: As alterações metabólicas mais precoces foram a hipertrigliceridemia e a resistência insulínica, culminando no surgimento do DM à época da puberdade, sendo as mutações no gene AGPAT2 as mais frequentes em nossa casuística.

OBJECTIVE: To report the genetic and metabolic profile of patients with Berardinelli-Seip syndrome (BSCL) followed at Instituto da Criança, HC-FMUSP. SUBJECTS AND METHODS: Patients with clinical features of BSCL (n = 5), all female, were evaluated through serum levels of glucose, insulin, lipids, leptin, and liver enzymes. Abdominal sonography and DNA analysis were also performed. RESULTS: Leptin deficiency and hypertriglyceridemia were found in all the patients. Three progressed to diabetes mellitus. Four patients have mutations in AGPAT2 gene and one have a mutation in CAV1 gene. CONCLUSION: The earliest metabolic abnormalities were hypertriglyceridemia and insulin resistance, culminating in the onset of diabetes at the time of puberty. Mutations in the AGPAT2 gene were the most frequent in our patients.

Fundamento: A síndrome de Berardinelli-Seip (SBS) ou lipodistrofia generalizada congênita acomete, frequentemente, o aparelho cardiovascular e também promove anormalidades metabólicas que envolvem os metabolismos glicídico e lipídico. Objetivo: Avaliar a prevalência das anormalidades cardiovasculares e metabólicas em portadores da SBS. Métodos: Vinte e dois pacientes do Estado do Rio Grande do Norte (Brasil), com diagnóstico da SBS, foram submetidos a avaliação clínica, eletrocardiograma de repouso, ecodopplercardiograma, radiografia de tórax, eletrocardiografia dinâmica de 24 horas, teste ergométrico e análise laboratorial. Resultados: Os pacientes eram, predominantemente, adultos jovens, sendo a maioria do sexo feminino. A totalidade da amostra apresentou resistência à insulina, acanthosis nigricans e HDL-colesterol diminuído. A presença de esplenomegalia, hepatomegalia, diabetes mellitus tipo II e triglicérides elevados era constante. A síndrome metabólica foi caracterizada na maioria dos pacientes, com predominância no sexo feminino e com um alto grau de consanguinidade paterna. A hipertensão arterial sistêmica e a pré-hipertensão foram encontradas em mais da metade dos pacientes (77,3 por cento). O ecodopplercardiograma mostrou a presença de hipertrofia concêntrica do ventrículo esquerdo (50 por cento), hipertrofia excêntrica do ventrículo esquerdo (4,5 por cento) e geometria normal do ventrículo esquerdo (45,5 por cento). Elevada taxa de arritmia foi evidenciada no holter, tais como extrassístoles ventriculares, extrassístoles supraventriculares e taquicardia supraventricular sustentada. A incompetência cronotrópica (54,5 por cento) foi observada no teste ergométrico. Conclusão: Anormalidades cardiovasculares e metabólicas foram observadas em elevada prevalência em indivíduos jovens e assintomáticos com SBS. Esses achados apontam para a necessidade de acompanhamento cardiológico sistemático e de medidas preventivas nesse grupo de risco.

Background: Berardinelli-Seip syndrome (BSS) or Generalized Congenital Lipodystrophy often affects the cardiovascular system and also promotes metabolic abnormalities involving glycidic and lipid metabolisms. Objective: To assess the prevalence of cardiometabolic abnormalities in patients with BSS. Methods: Twenty-two patients from the state of Rio Grande do Norte, Brazil, diagnosed with BSS, underwent clinical evaluation, resting electrocardiogram, echodopplercardiogram, chest X-ray, 24-hour ambulatory electrocardiogram monitoring, exercise testing and laboratory analysis. Results: The patients were predominantly young adults, most of whom women. The whole sample showed insulin resistance, acanthosis nigricans and diminished HDL-cholesterol. The presence of splenomegaly, hepatomegaly, type II diabetes and elevated triglycerides was constant. Metabolic syndrome was characterized in most patients, which were predominantly women and with a high degree of paternal consanguinity. SAH and prehypertension blood pressure were found in more than half of the patients (77.3 percent). The echodopplercardiogram showed the presence of CLVH (50 percent), eccentric left ventricular hypertrophy (4.5 percent), and normal left ventricular geometry (45.5 percent). High arrhythmia rates were observed by Holter monitoring, such as ventricular ectopic beats, supraventricular ectopic beats and sustained supraventricular tachycardia. Chronotropic incompetence (54.5 percent) was observed during exercise testing. Conclusion: A high prevalence of cardiovascular and metabolic abnormalities was observed in young asymptomatic individuals with BSS. These findings point to the need for systematic cardiological follow-up and of preventive measures in this high-risk group.

Infantile Myofibromatosis(Congenital Generalized Fibromatosis): Associated with multiple congenital malformations and basaloid follicular hamartomas in the skin

Infantile myofibromatosis with systemic involvement is a very rare disease and is characterized by numerous nodules composed of spindle cells of a myofibroblastic nature. There are often disseminated throughout the subcutis, muscle, skeleton and viscera. We report an autopsy case of infantile myofibromatosis in a stillborn female fetus of 32 weeks of gestation. The nodules, Imm to 2 cm, were found over the whole body and viscera. The involved viscera were the heart, tongue, esophagus, gastrointestinal tract, portal areas of the liver, spleen anc pancreas. There were also associated malformations, viz., frontal meningoencephalocele, flexion defer-mities, syndactyly, cleft palate, agenesis of corpus callosum, pachygyria, diaphragmatic hemia, renal hypoplasia, etc. Multiple basaloid follicular hamartomas of the skin were noted on the face and extremeties. There are no previous reports in the literature of infantile myofibromatosis in conjunction with the above skin lesion and congenital malformations.
