As distrofias musculares de cinturas (DMC) representam um grupo heterogêneo de desordens hereditárias e degenerativas da musculatura esquelética, com evolução progressiva, caracterizadas principalmente pelo acometimento predominante das cinturas escapular e/ou pélvica. São classificadas de acordo com o padrão de herança e o gene envolvido, podendo ser autossômicas dominantes ou autossômicas recessivas. Embora as disfunções mitocondriais tenham sido pouco descritas nas DMC, alguns estudos apresentaram evidências morfológicas e bioquímicas de alterações secundárias na cadeia respiratória mitocondrial. As razões envolvidas em tais disfunções na DMC permanecem pouco compreendidas. Portanto, é imprescindível uma caracterização detalhada da disfunção mitocondrial nos pacientes com DMC para uma melhor compreensão dos processos fisiopatológicos envolvidos na doença. Os objetivos do estudo foram: quantificar a CoQ10 em fragmentos do músculo esquelético de pacientes com DMC; quantificar a atividade enzimática de cada complexo da cadeia respiratória isoladamente; quantificar a atividade dos complexos II+III em conjunto como avaliação indireta da CoQ10; verificar a relação entre a área relativa de fibras musculares no fragmento de biópsia e o grau de disfunção mitocondrial nesses fragmentos; correlacionar a função mitocondrial com parâmetros clínicos de pacientes com DMC. Participaram do estudo 21 pacientes com DMC e 9 controles saudáveis. Os parâmetros clínicos incluídos foram idade no momento da biópsia, idade de início dos sintomas e tempo de evolução da doença. A análise do metabolismo mitocondrial foi realizada por: quantificação da coenzima Q10 nos fragmentos de biópsia muscular e quantificação da atividade dos complexos enzimáticos mitocondriais I, II, III, II+III e IV da cadeia respiratória e da enzima da matriz mitocondrial citrato sintase. Foram correlacionados os parâmetros clínicos, a proporção de fibras na biópsia muscular e os resultados das análises bioquímicas para a caracterização da função mitocondrial. A média dos pacientes com DMC em relação à idade no momento da biópsia, início dos sintomas e tempo de evolução da doença foi de 28,9 anos (DP ±11,7), 16,7 anos (DP ±10,3) e 12,1 anos (DP ±10,9), respectivamente. O grupo controle apresentou média de idade no momento da biópsia de 29,6 anos (DP ±10,3). A dosagem média de CoQ10 nos fragmentos de biópsia de pacientes com DMC foi de 17,9 µg/g de tecido (DP ±9,2) e nos fragmentos dos controles foi de 29,5 µg/g de tecido (DP ±4,4). Não foi observada alteração das atividades isoladas dos complexos enzimáticos da cadeia respiratória. Houve deficiência da atividade do conjunto de complexos II+III nos pacientes com DMC. A média da área ocupada por fibras musculares nos pacientes com DMC foi de 58,5% (DP ±26,1%) e nos controles foi de 76,35% (DP ±1,9%). Observou-se correlação moderada entre a quantidade de CoQ10 e a área relativa de fibras musculares (r= 0,57 e p= 0,007). Não houve correlação da CoQ10 com os parâmetros clínicos. No presente estudo, concluímos que existe uma deficiência secundária de CoQ10 em pacientes com DMC, sendo um achado importante para melhor entendimento do acometimento mitocondrial nessa doença e uma abordagem terapêutica mais eficaz. / The limb-girdle muscular dystrophy (LGMD) is a group of inherited and degenerative disorders of the skeletal muscle, with a progressive clinical course and predominant involvement of the scapular and/or pelvic girdles. They are classified according to the pattern of inheritance (autosomal dominant or autosomal recessive) and the gene involved. Mitochondrial dysfunction has been reported in the LGMD, some studies have described morphological and biochemical evidences of secondary mitochondrial respiratory chain alterations in patients with LGMD. The reasons involved in such dysfunctions in the LGMD remain poorly understood. Therefore, a detailed characterization of the mitochondrial dysfunction in patients with LGMD allows a better understanding of the pathophysiological processes involved in the disease. Therefore, a detailed characterization of mitochondrial dysfunction in patients with LGMD is essential for a better understanding of the pathophysiological processes involved in the disease. The purposes of the study were: to quantify CoQ10 in fragments of muscle biopsy of patients with LGMD; quantify the enzymatic activity of each respiratory chain complex isolated; quantify the activity of the II + III complexes together as an indirect measure of CoQ10; to verify the relation between the relative area of muscular fibers in the fragment of biopsy and the degree of mitochondrial dysfunction in these fragments; correlate mitochondrial function with clinical parameters of patients with LGMD. Twenty-one patients with LGMD and nine healthy controls participated in the study. The clinical parameters included were age at the time of biopsy, age of onset of symptoms and time of disease progression. The analysis of mitochondrial metabolism was performed by: quantification of CoQ10 in the muscle biopsy fragments and quantification of the activity of the mitochondrial enzyme complexes I, II, III, II + III and IV of the respiratory chain and the enzyme of the mitochondrial matrix citrate synthase. We analyzed the correlation of the clinical parameters, the proportion of fibers in the muscle biopsy and the results of the biochemical analyzes for the characterization of the mitochondrial function. For the LGMD groups, the mean age at the time of biopsy, onset of symptoms and disease duration was 28.9 years (SD ± 11.7), 16.7 years (SD ± 10.3) and 12.1 years (SD ± 10.9), respectively. The control group presented a mean age at the time of biopsy of 29.6 years (SD ± 10.3). The mean CoQ10 dosage in the biopsy specimens of patients with LGMD was 17.9 ?g / g tissue (SD ± 9.2) and in the fragments of the controls was 29.5 ?g / g tissue (SD ± 4, 4). No alterations were observed in the isolated activities of the enzymatic complexes of the respiratory chain. There was a deficiency of the activity of complexes II + III in patients with LGMD. The mean area occupied by muscle fibers in patients with LGMD was 58.5% (SD ± 26.1%) and in controls it was 76.35% (SD ± 1.9%). A moderate correlation was observed between the amount of CoQ10 and the relative area of muscle fibers (r = 0.57 and p = 0.007). There was no correlation of CoQ10 with clinical parameters. In the present study, we conclude that there is a secondary deficiency of CoQ10 in patients with LGMD, which has important implications in the understanding of mitochondrial involvement in this group of diseases and the development of a more effective therapeutic approach.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Objective: To report the clinical and muscle biopsy findings from the recessive forms of limb girdle muscular dystrophies (LGMD type 2) seen in the state of CearÃ, Northeast of Brazil. Design: Case series. Setting: Tertiary care clinic, University hospital. Patients and Methods: We studied 41 patients from 32 families with chronic progressive weakness in a limb-girdle distribution seen at a tertiary care hospital. All patients were born in the State of CearÃ. Patients with autossomal dominant pattern or facial involvement were excluded. Muscle biopsies specimens were immunostained for dystrophin, sarcoglycan, dysferlin, myotilin, merosin and emerin on all cases. Results: We found a specific protein deficiency in 24 patients (58.5%) from 20 families. Among these patients 11 (45.8%) had sarcoglycanopathy and 13 (54.2%) had dysferlinopathy and the pattern of inheritance was autosomal recessive or sporadic. Eletrocardiographic changes were seen in 6 (54.5%) patients with sarcoglycanopathy. Conclusion: Sarcoglicanopathies and disferlinopathies represent more than 60% of the cases of families with LGMD type 2 in this series from Northeast Brazil. Immunohistochemistry is still a very important tool for classification of LGMDs if genetic testing is not available or limited. Further studies are necessary to characterize the genetic background of the different LGMD families and to further characterize the other subtypes of LGMD type 2 in Brazil. / Objetivo: CaracterizaÃÃo clÃnica e de achados da biÃpsia muscular de formas recessivas de distrofias musculares de cinturas (DMPC tipo 2) no Estado do CearÃ, Nordeste do Brasil.

Devido à imaturidade biológica que ocorre na adolescência, conjectura-se que os fatores associados ao desenvolvimento dessa dor em adolescentes gestantes sejam diferentes daqueles encontrados na mulher adulta. O objetivo deste estudo foi avaliar a associação da dor lombopélvica prévia à gestação com o desenvolvimento da dor na cintura pélvica, bem como os fatores associados ao nível de incapacidade funcional em gestantes adolescentes. Foi realizado um estudo do tipo caso-controle com adolescentes gestantes, atendidas em duas unidades de referência da região metropolitana de Recife, Pernambuco, Brasil. Foram avaliadas 404 adolescentes (73 casos e 331 controles). No grupo caso, foram incluídas gestantes com idade entre 10 e 19 anos, idade gestacional entre a 28ª e a 40ª semana de gestação e presença de dor na cintura pélvica. No grupo controle foram incluídas as gestantes com ausência de dor na cintura pélvica. Um modelo de regressão logística foi utilizado para identificar os fatores associados à ocorrência de dor da cintura pélvica. Além disso, foi realizada uma análise no grupo de casos sobre os fatores associados à incapacidade funcional. A média da intensidade da dor nas 73 adolescentes com dor na cintura pélvica foi de 58 mm (Desvio Padrão [DP]: 20,13) em uma escala de 100 mm. Em relação à localização e envolvimento das articulações pélvicas, obteve-se a seguinte distribuição: 46 (63%) síndrome sacroilíaca bilateral; 17 (23,3%) síndrome da cintura pélvica e 10 (13,7%) síndrome sacroilíaca unilateral. No modelo de regressão multivariada, permaneceram associados com a dor na cintura pélvica os seguintes fatores: transtorno mental comum (Odds Ratio [OR]: 2,27; Intervalo de Confiança 95% [IC95%]: 1,23 a 4,18), dor lombar na menstruação (OR: 2,10; IC95%: 1,16 a 3,80) e trabalho árduo (OR: 1,95; IC95%: 1,13 a 3,35). No grupo de gestantes com dor na cintura pélvica, o coeficiente de determinação encontrado no modelo ajustado indica que 22% da variabilidade total da incapacidade funcional (ODI) em gestantes adolescente são explicadas pelos fatores transtorno mental comum (SRQ20), intensidade da dor na cintura pélvica (EAV) e idade gestacional (IG), expressos na seguinte equação: ODI (predito) = -18,2 + 0,81 x SRQ20 + 0,25 x EAV + 0,73 x IG. Conclui-se, portanto, que não houve associação entre a história de dor lombopélvica prévia à gestação e a presença de dor na cintura pélvica relacionada com a gestação em adolescentes. No entanto, a dor lombar na menstruação, o trabalho árduo e o transtorno mental comum foram fatores que se mostraram associados com a dor na cintura pélvica nessa população. Também foi evidenciado que a intensidade da dor e a presença de transtorno mental comum encontram-se associados com a incapacidade funcional dessas adolescentes. / Pelvic girdle pain is a common musculoskeletal dysfunction during pregnancy. Due to biological immaturity and unfavorable psychosocial conditions, pregnancy in adolescence may be associated with pelvic girdle pain. The aim of this study was to assess the association between lumbopelvic pain before pregnancy and level of functional disability and pelvic girdle pain related to pregnancy in adolescents. A case-control study was conducted with pregnant adolescents, treated at two specialist units in the city of Recife, Pernambuco state, Brazil. A total of 404 adolescents (73 cases and 331 controls) were assessed. The case group included pregnant adolescents between the ages of 10 and 19 years, gestational age between 28 and 40 weeks and exhibiting pelvic girdle pain. The control groups consisted of pregnant adolescents with no pelvic girdle pain. A logistic regression model was used to identify the factors associated with the occurrence of pelvic pain. The measure of pain intensity in 73 adolescents with pelvic pain was 58 mm (standard deviation [SD]: 20.13) on a scale of 100 mm. In relation to location and pelvic joint involvement, the following distribution was obtained: 46 (63%) bilateral sacroiliac syndrome; 17 (23.3%) pelvic congestion syndrome and 10 (13.7%) unilateral sacroiliac syndrome. In the multivariate regression model the following variables were associated with pelvic pain in pregnant adolescents: common mental disorder (Odds Ratio [OR]: 2.27; 95% Confidence Interval [95%CI]: 1.23 to 4.18), menstrual back pain (OR: 2.10; 95%CI: 1.16 to 3.80) and strenuous work (OR: 1.95; 95%CI: 1.13 to 3.35). In the group of pregnant adolescents with pelvic girdle pain, the coefficient of determination found in the adjusted model indicates that 22% of total variability in functional disability (ODI) in pregnant adolescents is explained by the following variables: common mental disorder (SRQ20), pelvic pain intensity (EAV) and gestational age (GA), expressed in the following equation: ODI (predictive) = -18.2 + 0.81 x SRQ20 + 0.25 x EAV + 0.73 x GA. It is concluded, therefore, that there is no association between history of lumbopelvic pain prior to pregnancy and the presence of pelvic girdle pain related to pregnancy in adolescents. However, menstrual back pain, strenuous work and common mental disorder were factors associated with pelvic girdle pain in this population. It was also shown that pain intensity and common mental disorder in adolescents with pregnancy-related pelvic girdle pain are closely related to the functional disability of these women.
