Introduction. Spontaneous Escherichia coli meningitis is an infrequent condition in adults and is associated with some predisposing factors, including severe Strongyloides stercoralis (SS) infections. Case Presentation. A 43-year-old Hispanic man, with history of travelling to the jungle regions of Peru and Brazil two decades ago, and who received prednisone due to Bell's palsy for three weeks before admission, presented to the Emergency Department with diarrhea, fever, and hematochezia. A week after admission he developed drowsiness, meningeal signs, abdominal distension, and constipation. A cerebrospinal fluid culture showed extended spectrum β-lactamase producing E. coli. A colonoscopy was performed and showed pancolitis. Three days after the procedure the patient became unstable and developed peritoneal signs. He underwent a laparotomy, which ended up in a total colectomy and partial proctectomy due to toxic megacolon. Three days later the patient died in the intensive care unit due to septic shock. Autopsy was performed and microscopic examination revealed the presence of multiple Strongyloides larvae throughout the body. Conclusion. Strongyloides stercoralis infection should be excluded in adults with spontaneous E. coli meningitis, especially, if gastrointestinal symptoms and history of travelling to an endemic area are present. Even with a proper diagnosis and management, disseminated strongyloidiasis has a poor prognosis.
OBJETIVO: Investigar la presencia de amiloidosis secundaria (AA) en pacientes con diagnóstico de artritis reumatoide (AR). MATERIALES Y MÉTODOS: Se evaluó tiempo de enfermedad (TE), presencia de manifestaciones extraarticulares, capacidad funcional y estadio de progresión anatómica, hemograma, velocidad de sedimentación globular, factor reumatoide (FR) (Test de Látex), albúmina sérica y examen completo de orina. Se realizó aspirado de grasa subcutánea periumbilical. El tejido se coloreó con rojo Congo y observó por microscopía óptica y luz polarizada, siendo positiva la birrefringencia verde manzana. RESULTADOS: Se estudió 81 pacientes con diagnóstico de AR (criterios del ACR), 71 fueron mujeres y 10 varones, con rango de edad 31 a 80 años. 75/81 fueron FR (+), 3/81 AA (+). El TE promedio fue 14,74 años para los AA (-) y 20,3 para los AA (+). Sólo en un paciente se halló amiloide en biopsia renal. CONCLUSIONES: En nuestra serie la frecuencia fue menor a lo reportado. Los pacientes con amiloidosis tuvieron títulos altos de FR y TE más prolongado.
