ABSTRACT

Las Vasculitis ANCA pueden causar lesiones diversas a lo largo del tracto gastrointestinal pero la afectación esofágica es infrecuente. Dentro del espectro de lesiones que pueden aparecer un hematoma esofágico no es una mención habitual en la bibliografía. Presentamos el caso de una mujer de 67 años con diagnóstico de vasculitis ANCA asociada (VAA) y hematemesis. Consideramos que el hematoma esofágico es una manifestación atípica de una enfermedad infrecuente. La prevalencia real de este tipo de manifestaciones atípicas es desconocida ya sea por su carácter infrecuente o por la baja tasa de reportes, por lo que creemos es de utilidad la publicación de este tipo de manifestaciones.


ANCA associated vasculitis (AAV) can cause various injuries along the gastrointestinal tract, but esophageal involvement is rare. Within the spectrum of lesions that may occur an esophageal hematoma is not a common mention in the literature. We present the case of a 67-year-old woman diagnosed with AAV and hematemesis. We consider the esophageal hematoma to be an atypical manifestation of a rare disease. The actual prevalence of this type of atypical manifestations is unknown, either due to its infrequent nature or the low reporting rate, so we believe that the publication of this type of manifestations is useful.

ABSTRACT

La enfermedad de Still del adulto (ESA) es un proceso inflamatorio sistémico, de etiología desconocida, que se caracteriza por fiebre, artritis y eritema evanescente, además de valores elevados de ferritina sérica. Sin embargo, hasta la fecha, no hay una prueba definitiva de laboratorio o de imagen disponible para su diagnóstico, por lo tanto la ESA es un diagnóstico de exclusión. Presentamos el caso de una mujer de 44 años con manifestación cutánea atípica de ESA y cuadro clínico de 1 año de evolución caracterizado por fiebre de 40°C, linfadenopatía, hiperferritinemia, y que en la sistemática de estudio presentó positividad para anti-CCP (anticuerpo antipéptido cíclico citrulinado).


Adult Still's disease (ASD) is a systemic inflammatory process, of unknown etiology, characterized by fever, arthritis and evanescent erythema, in addition to elevated serum ferritin values. However, to date, there is no definitive laboratory or imaging test available to diagnose it, therefore ASD is a diagnosis of exclusion. We present the case of a 44-year-old woman with atypical cutaneous manifestation of ESA and positivity of ACPA (anti-cyclic citrullinated peptide antibody).

ABSTRACT

We have determined the phospholipid composition of E. gracillis under different environmental conditions. Half of the phosphoglycerides was phosphatidylcholine, regardless of growth conditions, but differences were noted in the distribution of the remaining lipids. Autotrophic, green, light-grown euglenas had 31% more amino-containing lipids (phosphatidylethanolamine and phosphatidylserine) than the heterotrophic, white, dark-grown cells. In contrast, dark-grow cells had 47% more anionic lipids, such as the ones belonging to the "phosphatidynositol cycle" (phosphatidylinositol, phosphatidylinositol-phosphate phosphatidylinositol-bis-phosphate and phosphatidic acid) plus cardiolipin. The results suggest an adaptation of some biosynthetic and degradative phospholipid pathways to autotrophic and to heterotophic growth
