ABSTRACT

A esclerodermia cursa com espessamento importante da pele, o qual pode afetar a mobilidade e função das mãos. O objetivo deste estudo foi avaliar o acometimento das mãos em pacientes com esclerodermia sistêmica. É estudo transversal de 43 pacientes com esclerodermia para dados clínicos e epidemiológicos, presença de STC (síndrome de túnel do carpo), força da mão medida pelo dinamômetro Jamar®, e função da mão pelos questionários de Hamis e Cochin. Estes pacientes foram comparados com 43 controles. Em conclusão, pacientes de esclerodermia têm pior função da mão do que controles. A presença de queixas musculoesqueléticas afeta destreza e força da mão, enquanto que a presença de STC influencia na presença de parestesias. O grau de envolvimento cutâneo e a forma da esclerodermia não modificaram a função da mão.


Scleroderma progresses with significant thickening of the skin, which can affect the mobility and function of the hands. The aim of this study was to evaluate the involvement of the hands in patients with systemic scleroderma. It is a cross-sectional study of 43 patients with scleroderma for clinical and epidemiological data, presence of CTS (carpal tunnel syndrome), hand strength measured by the Jamar® dynamometer, and hand function by the Hamis and Cochin questionnaires. These patients were compared with 43 controls. In conclusion, scleroderma patients have worse hand function than controls. The presence of musculoskeletal complaints affects dexterity and hand strength, while the presence of CTS influences the presence of paresthesias. The degree of skin involvement and the form of scleroderma did not change hand function.

ABSTRACT

ABSTRACT Introduction: Reynolds syndrome (RS) is an autoimmune disorder characterized by overlapping primary biliary cirrhosis (PBC) and limited cutaneous systemic sclerosis (lcSSc). Some published cases do not report pulmonary arterial hypertension (PAH), and diagnoses are usually based on clinical, immunological and histological findings, mainly focused on dermatologic features, on those associated with Sjogren's syndrome, or on an interesting presentation of malignant thymoma; only one case of reported PAH was found, but it was an image report. Case Presentation: This paper reports the case of a 75-year-old woman who presented with some of the features mentioned above, severe PAH, dyspnea for one month and two weeks of purulent expectoration, as well as generalized pruritus, nasal telangiectasias, Raynaud phenomenon, sclerodactyly, and high levels of alkaline phosphatase and transaminases. Pulmonary arterial hypertension was documented through a transthoracic echocardiogram, and inmunoflorecence reported mitochondrial and centromere patterns of antinuclear-antibodies. Consequently, RS was diagnosed and phosphodiesterase type-5 inhibitors were started for PAH treatment resulting in the improvement of dyspnea. Conclusion: Dyspnea could be caused by many conditions, but in the presence of clinical and physical findings, it suggests an autoimmune disorder. Scleroderma should be considered and, additionally, PAH should be investigated since it is present in up to 10% of patients, conferring a worse prognosis. Internists should keep in mind that these disorders may be associated with other autoimmune diseases.

ABSTRACT

OBJETIVO: O objetivo deste estudo foi comparar a resposta dilatadora dependente e independente do endotélio em pacientes portadores de esclerose sistêmica limitada (ESL) com aquela de indivíduos sadios de mesmo gênero, idade e cor. MÉTODOS: Vinte mulheres adultas, não obesas, não tabagistas, não diabéticas, não dislipidêmicas, não hipertensas, que preencheram os critérios para esclerose sistêmica (ES) segundo o American College of Rheumatology, foram submetidas ao exame de Doppler de artéria braquial do membro superior direito. Foi analisada a resposta dilatadora, dependente do endotélio, após isquemia induzida com esfigmomanômetro por cinco minutos no braço direito, e a resposta dilatadora, independente do endotélio, após administração de 300 mcg de nitroglicerina (NTG) sublingual. Esses resultados foram comparados com a resposta obtida em indivíduos sadios. RESULTADOS: O diâmetro longitudinal da artéria braquial (DAB) foi significativamente menor na fase basal 1 nos pacientes com ESL (3,57 ± 0,52 mm e 3,93 ± 0,39 mm, respectivamente no grupo paciente (P) e grupo-controle (C), P = 0,005). Não foi encontrada diferença estatisticamente significativa entre a velocidade das hemácias (VH) após isquemia/hiperemia reativa (HR) e após NTG (110,2 ± 43,86 cm/s vs. 102,0 ± 25,89 cm/s e 63,80 ± 17,69 cm/s vs. 65,4 ± 12,90 cm/s nos grupos P e C, após HR e NTG, respectivamente). Também não foi encontrada diferença significativa entre o DAB após HR e após NTG (3,77 ± 0,59 mm vs. 4,14 ± 0,49 mm e 4,44 ± 0,64 mm vs. 4,70 ± 0,58 mm nos grupos P e C, após HR e NTG, respectivamente). CONCLUSÃO: Embora o grupo de pacientes com ESL tenha apresentado menor DAB basal, a resposta dilatadora dependente e independente do endotélio se manteve preservada em ambos os grupos.


OBJECTIVES: The aim of this study was to compare the brachial artery endothelium-dependent and endothelium-independent dilating responses in patients with limited systemic sclerosis (LSSc) with those of healthy subjects of the same gender, age and color. METHODS: Twenty adult, non-obese, non-smoker, non-diabetic, non-dyslipidemic, and non-hypertensive women, who fulfilled the American College of Rheumatology criteria for the diagnosis of SSc, were submitted to right brachial artery Doppler ultrasound. The vasodilating responses were analyzed as follows: the endothelium-dependent dilating response, after a 5-minute ischemia in the right arm; and the endothelium-independent dilating response, after administering 300 mcg of nitroglycerin (NTG) sublingually. The results were compared with the response obtained in healthy subjects. RESULTS: Brachial artery longitudinal diameter was significantly low at baseline 1: 3.57 ± 0.52 mm and 3.93 ± 0.39 mm for the LSSc group and the control group, respectively, P = 0.005. The vascular reactivity after the ischemia/reactive hyperemia and the NTG showed no significant difference between the groups (8.60 ± 5.45 mm vs. 9.26 ± 5.91 mm and 25.01 ± 12.55 mm vs. 19.59 ± 7.94 mm for the LSSc and control groups, respectively). Also, no statistically significant difference was found between red blood cell velocity (RBCV) after reactive hyperemia and NTG (110.2 ± 43.86 cm/s vs. 102.0 ± 25.89 cm/s and 63.80 ± 17.69 cm/s vs. 65.4 ± 12.90 cm/s in the LSSc and control groups, respectively). CONCLUSION: Although the LSSc group showed lower brachial artery diameter, the endotheliumdependent and the endothelium-independent dilating responses were preserved in both groups.

ABSTRACT

FUNDAMENTOS: A esclerodermia é uma colagenose relativamente rara, cujo perfil de autoanticorpos está associado a diferentes manifestações clínicas. A prevalência de autoanticorpos na esclerodermia sofre influência racial e genética. OBJETIVO: Estudar a prevalência dos anticorpos anti-Scl-70, anticentrômero e anti-U1-RNP em pacientes com esclerodermia do sul do Brasil e verificar suas associações às manifestações clínicas. MÉTODOS: Estudo retrospectivo de análise de 66 pacientes com esclerodermia para presença de anti-Scl-70, anticentrômero (ACA) e anti-U1-RNP e de manifestações clínicas como: Raynaud, cicatrizes estelares, necrose digital, telangiectasias, calcinose, fibrose pulmonar, pleurites, pericardites, miocardiopatias, artralgias e artrites, grau de esclerose da pele, contraturas articulares e atritos de tendão, hipertensão pulmonar, manifestações esofágicas e crise renal. RESULTADOS: A prevalência do anti-Scl-70 foi de 17,8 por cento, a do ACA, de 33,3 por cento, e a do U1 RNP foi de 11,8 por cento. O anti-Scl-70 estava associado à forma difusa da doença (p=0,015), presença de miocardiopatias (p=0,016) e de cicatrizes estelares (p=0,05); o anticentrômero foi mais comum na forma limitada, embora sem significância estatística e mostrou-se protetor para as miocardiopatias (p=0,005). O anti-U1-RNP foi mais comum nas formas de superposição (p=0,0004). CONCLUSÃO: A prevalência e o perfil de associações clínicas dos autoanticorpos em esclerodermia de pacientes brasileiros assemelham-se aos da literatura mundial.


BACKGROUND: Scleroderma is a fairly rare connective tissue disease whose autoantibody profile is associated with different clinical manifestations. The prevalence of autoantibodies in scleroderma is influenced by race and genetics. OBJECTIVE: To study the prevalence of anti-Scl-70, anti-centromere (ACA) and anti-U1-RNP antibodies in patients with scleroderma in southern Brazil and verify their association with clinical manifestations of the disease. METHODS: A retrospective study involving 66 patients with scleroderma for the presence of anti-Scl-70, anti-centromere and anti-U1-RNP and of clinical manifestations such as Raynaud's phenomenon, digital micro scars, digital necrosis, telangiectasias, calcinosis, pulmonary fibrosis, pleuritis, pericarditis, cardiomyopathy, arthralgia and arthritis, skin sclerosis, joint contractures, tendon friction rubs, pulmonary hypertension, esophageal disorders and renal crisis. RESULTS: The prevalence of anti-Scl-70 was 17.8 percent , that of ACA was 33.3 percent and the prevalence of U1 RNP was 11.8 percent. Anti-Scl-70 was associated with the diffuse form of the disease (p = 0.015), presence of cardiomyopathies (p = 0.016) and digital micro scars (p = 0.05). Anti-centromere was more common in the limited form, although it was not statistically significant, and had a protective role associated with cardiomyopathies (p = 0.005). Anti-U1-RNP was more common in the overlap forms (p = 0.0004). CONCLUSION: The prevalence and profile of clinical associations of autoantibodies in Brazilian patients with scleroderma are similar to those found in the literature.

ABSTRACT

Isquemia é comum em esclerodermia sistêmica e é causada por vasoespasmo e trombose. As autoras analisaram a associação de eventos vasculares periféricos e anticorpos anticardiolipinas (aCl) em 54 esclerodérmicos. Em 100 por cento deles existia Raynaud; 59,2 por cento apresentaram cicatrizes estelares; 43,3 por cento, telangiectasias; 14,8 por cento, fenômenos tromboembólicos periféricos. ACl IgG foram positivos em 9,2 por cento dos casos e o IgM, em 7,4 por cento. Fenômenos embólicos periféricos estão associados a aCl IgG (p=0,03), não se encontrando associação com demais manifestações.


Ischemia is common in systemic scleroderma and it is caused by vasospasm and thrombosis. In the present study we analyzed the association of peripheral vascular events and anticardiolipin (aCl) antibodies in 54 patients suffering from systemic scleroderma. The results showed that 100 percent of the patients presented Raynaud; 59.2 percent presented digital micro scars; 43.3 percent, presented teleangiectasies and 14.8 percent, presented peripheral thromboembolism. ACl IgG were positive in 9.2 percent and IgM, in 7.4 percent. Peripheral tromboembolic phenomena had a positive association with aCl IgG (p=0.03). No other associations were found.

ABSTRACT

FUNDAMENTOS: A capilaroscopia periungueal tem sido largamente utilizada para diagnóstico de esclerodermia sistêmica. Mais recentemente descobriu-se que também pode predizer o envolvimento de órgãos internos. OBJETIVO: Verificar se a capilaroscopia periungueal mostra correlação com a gravidade da esclerodermia sistêmica. MÉTODOS: Foram estudados a capilaroscopia periungueal de 14 pacientes com esclerodermia sistêmica quanto ao número médio de capilares dilatados e às áreas de desvascularização; a medida do envolvimento cutâneo pelo índice de Rodnan modificado; e o grau de gravidade da doença segundo escala proposta por Medsger e cols. RESULTADOS: Os resultados mostraram boa correlação do índice de desvascularização com o grau de gravidade da doença (p = 0.04). Não se encontrou correlação entre o aparecimento de dilatação capilar e o grau de gravidade da doença (p = 0.572). O grau de espessamento cutâneo não mostrou correspondência com o grau de dilatação capilar (p = 0.76), embora mostrasse tendência de associação com desvascularização (p = 0.07). CONCLUSÃO: Os autores concluem que a presença de desvascularização à capilaroscopia periungueal pode ser usada como elemento indicador de maior gravidade da esclerodermia sistêmica.


BACKGROUND: Nail fold capillaroscopy has been largely used in the diagnosis of systemic sclerosis. It has been recently discovered that this test is also able to predict internal organ damage in systemic sclerosis. OBJECTIVE: This study was carried out to verify whether nail fold capillaroscopy findings are correlated with disease severity. METHODS: We studied nail fold capillaroscopy findings regarding dilated and avascular areas from 14 patients with systemic sclerosis; degree of skin involvement by means of a modified Rodnan index; and disease severity with the scale proposed by Medsger et al. RESULTS: The results showed that the number of avascular areas has a good correlation with disease severity (p = 0.043), but not with the number of dilated capillaries (p = 0.57). The degree of cutaneous thickening was not related to the degree of capillary dilatation (p = 0.76), but tended to be associated with avascular areas (p = 0.07). CONCLUSION: The authors conclude that the number of avascular areas in nail fold capillaroscopy could be used as a sign of disease severity in systemic sclerosis.
