Lichen sclerosus is an acquired inflammatory condition characterized by whitish fibrotic plaques, with a predilection for the genital skin. We performed scanning electron microscopy of the dermis from a lesion of lichen sclerosus. Normal collagen fibers could be easily found in deeper layers of the specimen, as well as the transition to pathologic area, which seems homogenized. With higher magnifications in this transitional area collagen fibers are adherent to each other, and with very high magnifications a pearl chain aspect became evident along the collagen fibers. In the superficial dermis this homogenization is even more evident, collagen fibers are packed together and round structures are also observed. Rupture of collagen fibers was not found and there were few inflammatory cells. These autoimmune changes of the extracellular matrix lead to the aggregation of immune complexes and/or changed matrix proteins along the collagen fibers, the reason why they seem hyalinized on light microscopy.
O líquen escleroso é uma afecção inflamatória caracterizada por placas esbranquiçadas fibróticas ocorrendo preferentemente na pele genital. Realizamos exame com microscópio eletrônico de varredura da derme de uma lesão de líquen escleroso. Ao exame as fibras colágenas normais puderam ser facilmente identificadas, bem como a transição para a área alterada, a qual aparece homogenizada. Nessa área as fibras parecem aderidas umas às outras e com aspecto em colar de pérolas. Na derme superficial essa homogenização é ainda mais evidente, com as fibras bem aderidas e ainda com as estruturas arredondadas. Ruptura das fibras não foi vista e poucas células inflamatórias foram observadas. Os fenômenos autoimunes que ocorrem na matriz extracelular nessa enfermidade devem levar à agregação de imunocomplexos e/ou proteínas alteradas nas fibras colágenas, por essa razão elas aparecem hialinizadas na microscopia óptica.

Resumo: As displasias esqueléticas ou osteocondrodisplasias são doenças genéticas que afetam o crescimento e o desenvolvimento do tecido ósseo e cartilaginoso produzindo, em geral, baixa estatura. Mutações em heterozigose no gene COL2A1 são responsáveis por uma série de displasias esqueléticas conhecidas como colagenopatias do tipo II que geralmente apresentam um padrão espondiloepifisário típico. Apesar das mutações no COL2A1 serem, em geral, "privadas", o estudo molecular desse gene em pacientes com fenótipos sugestivos de colagenopatia do tipo II pode contribuir seja para um melhor entendimento das colagenopatias do tipo II seja para refinar, quando possível, a correlação genótipo-fenótipo. O objetivo desse estudo foi investigar o gene COL2A1 numa coorte de pacientes com fenótipo de colagenopatia do tipo II de modo a melhorar o conhecimento sobre essas colagenopatias. Foram estudados 33 pacientes com fenótipo de colagenopatia do tipo II. A análise molecular foi feita por sequenciamento automático bidirecional direto do gene COL2A1, começando pelos domínios relacionados a cada fenótipo seguido de sequenciamento completo das regiões codificantes do gene quando as primeiras foram negativas. Foram identificadas alterações potencialmente deletérias em heterozigose em 23 dos 33 pacientes (69,7%): 18 alterações do tipo missense (11 inéditas, 7 descritas), 4 alterações que alteram sítio de splice (2 inéditas, 2 descritas) e uma deleção inédita. Das mutações do tipo missense encontradas, duas foram recorrentes em 5 pacientes: p.G594E e p.R989C. Ambas as mutações recorrentes foram associadas a fenótipos graves: a p.R989C foi observada em displasia espondiloepifisária congênita (SEDC) grave enquanto que a p.G594E foi associadaa 2 recém-nascidos com fenótipo de SEDC-letal. Para todas as mutações novas, a análise in silico, estudo em controles e/ou dos pais confirmaram a patogenicidade de todas elas. Concluindo, os resultados deste estudo permitiram a identificação de 14 mutações novas no gene COL2A1 e um melhor refinamento da correlação genótipo-fenótipo
Abstract: Skeletal dysplasias are genetic disorders that affect the growth and development of the bone and cartilage tissues producing, in general, short stature. Heterozygous mutations in the COL2A1 gene are responsible for a number of skeletal dysplasias that usually exhibit a pattern spondyloepiphyseal and are called type II collagenopathies. Although the mutations in COL2A1 are usually privates, molecular studies of this gene in patients with suggestive phenotypes can contribute to a better understanding of the type II collagenopathies. The aim of this study was to sequence the COL2A1 in a cohort of patients with type II collagenopathy phenotypes in order to refine the knowledge regarding the genotype-phenotype correlation. Thus, 33 patients with suggestive phenotype were studied. The molecular analysis was performed by automated Sanger bidirectional sequencing of the COL2A1 gene, starting with the domains related to each phenotype followed by whole sequencing of the gene coding regions when the first ones were negative. Potentially deleterious changes in heterozygosity were identified in 23 of 33 patients (69.7 %): 18 missense changes (11 undescribed), 4 changes that modify the splice site (2 undescribed) and a new deletion. The pathogenicity of the undescribed changes were confirmed by in silico analysis, study of control individuals and/or of the respective parents. Among the found missense mutations, two were recurrent and associated with severe phenotypes. These mutations, p.G594E and p.R989C, were found in five patients. The R989C change was observed in three children presenting a phenotype of spondyloepiphyseal dysplasia congenita (SEDC), which follow up showed a pattern of severe SEDC featured by severe disproportioned short stature with coxa vara and kyphoscoliosis. The G594E change was associated with two newborns presenting also a SEDC phenotype, however with lethal evolution. In conclusion, the results of this study allowed the identification of 14 new mutations in COL2A1 gene and a better refinement of the genotype-phenotype correlation

Full textAIM: To establish survival rates and analyse prognostic factors that influence the clinical evolution of patients with scleroderma. MATERIAL AND METHODS: The study comprised 317 patients diagnosed with scleroderma. Patients were classified according to the ARC and grouped according to degree of cutaneous involvement, into four clinical states; prescleroderma, diffuse type, limited type and scleroderma sine scleroderma. The various clinical symptoms were analysed (cutaneous, osteomuscular, digestive, pulmonary, cardiac and renal). Two capillaroscopic patterns were defined (slow and active) and laboratory data included general parameters and antinuclear antibodies (ACA, Anti-Scl-70). Accumulated survival rates at 10, 15, 20 and 35 years were calculated using the Kamplan-Meier method and the Cox method was used to establish future prognosis. RESULTS: The ratio of men to women was 9:1. Age at onset was 43.25 ± 16 years and age at diagnosis was 51.69 ± 15 years. The number in each clinical group was 24 (7.5%) prescleroderma, 64 (20%) diffuse type, 185 (58%) limited type and 44 (14%) scleroderma sine scleroderma. The mean 10-year survival rate was 93%, the 15-year rate was 86% and 20-year rate was 78%. Survival rates for the clinical subtypes were 93% for 10 years, 86% for 15 years and 78% for 20 years in the limited type group and 83% for 10 years, 60% for 15 years and 55% for 20 years in the diffuse type group. According to multivariable analysis, independent factors with bad prognosis were diffuse type, an age at onset of >60 years, the presence of fibrosis or pulmonary hypertension and renal sclerodermic crisis. DISCUSSION: Scleroderma is an illness that is characterised by a pronounced heterogeneity in its clinical symptoms, its development and its prognosis. Studies of survival rates have given differing results (ranging from 65 -100% at 10 years, depending on the series) due precisely to this variance of clinico-biological results between patients and also as a consequence of the methodologies used. Our results for survival are largely comparable to the majority of reported series. Prognostic factors also show a range of variance. However, as with those of other series, there is little doubt that the variables set out in the present study play a decisive role in survival rates for this disease. CONCLUSION: The independent prognostic factors that have significant consequences on evolution of scleroderma and subsequent survival rates are the diffuse type, age at onset, pulmonary involvement and renal crisis.

Full textPretende correlacionar la función pulmonar y los hallazgos tomográficos de los pacientes con enfermedad pulmonar intersticial difusa (EPID) secundaria a colagenopatía atendidos en el Hospital Nacional Edgardo Rebagliati Martins entre el 2010-2011. Se revisaron las historias clínicas y se obtuvieron los datos de las pruebas funcionales (espirometria , DLCO y pletismografía) realizadas a estos pacientes así como los hallazgos tomográficos de la TCAR. Se utilizó el Score severidad tomográfica de Piris i Sánchez para valorar el compromiso parenquimal de la EPID. Ingresaron al estudio 102 pacientes con edad mayor de 50 años en el 64.8%, sexo femenino (95.1%) e instrucción secundaria (57.8%). La etología más frecuente de la EPID fue esclerosis sistémica (36.3%) y artritis reumatoidea (29.4%).la sintomatología más frecuente fue la disnea (30.4%). La media de la CVF fue 75.90+-20.004% y el 40.2% fueron normales, la media de la SVC fue 78.10+-21.149% y el 41.2% fueron normales, la media de la DLCO fue 80.05+-26.47 ml/min/mmHg y el 51% fueron normales, la media del TLC fue 89.06+-21.296% y el 63.7% fue normales. El patrón tomográfico más frecuente fue el reticular-lineal. La severidad de la TCAR fue: leve (54.9%), moderada (33.3%) y severa (11.8%). Se concluyó que elestudio demuestra que el DLCO es la prueba de función pulmonar que más se correlaciona con el grado de severidad en la TCAR ,seguida de la pletismografía y espirometría pulmonar en los pacientes con enfermedad pulmonar intersticial difusa (EPID) secundaria a colagenopatía atendidos en el Hospital Nacional Edgardo Rebagliati Martins.
