A rare association of localized scleroderma type morphea, vitiligo, autoimmune hypothyroidism, pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis. Case report.

BACKGROUND: The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis. To our knowledge this is the first case of a morphea forming part of a multiple autoimmune syndrome (MAS) and presenting simultaneously with autoimmune thrombocytopenic purpura and central nervous system vasculitis. CASE PRESENTATION: We report an uncommon case of a white 53 year old female patient with LS as part of a multiple autoimmune syndrome associated with pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis presenting a favorable response with thrombopoietin receptor agonists, pulses of methylprednisolone and cyclophosphamide. CONCLUSION: Is likely that LS have an autoimmune origin and in this case becomes part of MAS, which consist on the presence of three or more well-defined autoimmune diseases in a single patient.

Panniculitis: another clinical expression of gout.

Gouty panniculitis is an unusual clinical manifestation of gout, characterized by the deposition of monosodium urate crystals in the lobular hypodermis. Its pathogenesis is poorly understood but is associated with hyperuricemia, and the clinical presence of indurate subcutaneous plaques, which may precede or appear subsequently to the articular clinical expression of tophaceous gout. The aim of this report is to describe the clinical characteristics and potential risk factors for the development of lobular panniculitis secondary to chronic tophaceous gout. This is a retrospective clinical review of 6 patients with gouty panniculitis seen at the rheumatology service at the National University of Colombia. All cases fulfill diagnostic criteria for gout. The presenting clinical characteristics of each case were analyzed. All 6 patients were men, with an average age of 26 years. Two patients initially presented with cutaneous manifestations, and in the remainder 4 joint involvements preceded the cutaneous manifestations. Articular involvement first developed in lower extremities, of intermittent nature, and subsequent occurrence of polyarthritis of upper and lower extremities. A positive family history of gout was observed in half of the patients. Smoking and high alcohol intake were relevant risk factors. On physical examination, all exhibited the presence of erythematous, irregular surface, deep indurate subcutaneous plaques. Biopsy of skin and deep dermis including panniculus revealed the presence of granulomatous inflammatory changes with deposition of amorphous eosinophilic material surrounded by palisading histocytes and lymphocytes. Characteristic negative birefringent monosodium urate crystals were observed in the synovial fluid of patients with arthritis. All patients exhibited high levels of serum uric acid and were non-complaint to treatment with allopurinol, NSAIDs, and colchicine. Gouty panniculitis should be considered in the differential diagnosis of panniculitis, especially in the presence of high levels of uric acid. It is usually observed in the third decade of life and may appear prior to the inflammatory articular manifestations of tophaceous gout.

Epidemiología de las vasculitis primarias en Colombia y su relación con lo informado para Latinoamérica / Epidemiology of primary vasculitis in Colombia and its relation with reported for latin america

Propuesta: las vasculitis primarias se expresan de forma variable entre pacientes y entre regiones, con frecuencias variables a través del mundo. Su incidencia promedio está calculada en 0,3 a 20 casos por millón de habitantes. Nosotros describimos la frecuencia de las vasculitis primarias en Colombia y la comparamos con lo informado en otros países de Latinoamérica (LA). Métodos: se revisó lo publicado en la literatura de vasculitis primaria en Colombia y en LA desde 1945 hasta 2007 en OLD Medline, Pub Med, BIREME, SciELO Colombia, LILACS. FEPAFEN, incluyendo publicaciones en inglés, español y portugués. La literatura incluye la información publicada del Hospital San Juan de Dios, Bogotá, Colombia y casos sin publicación enviados directamente por los autores. Nosotros calculamos el porcentaje para todos los casos que fueron informados para Colombia. Resultados: se identificaron 857 casos de vasculitis primaria en Colombia. La arteritis de Takayasu fue la vasculitis más frecuente en un 13,3% (114 casos) seguida de la enfermedad de Buerger en 11,2% (96 casos), las vasculitis cutáneas primarias y la poliarteritis nodosa en un 10% (86 casos) cada una. En niños, la vasculitis más frecuente fue la púrpura de Henoch Schönlein en un 24% (206 casos). En Latinoamérica se publicaron 177 artículos con 1605 casos informados. Se evidenció mayor presencia de arteritis de Takayasu en México y Brasil, y de poliangeítis microscópica en Chile y Perú. Conclusión: la mayoría de publicaciones sobre vasculitis primarias provienen de Europa, Norteamérica, Japón, Kuwait y Nueva Zelanda. Existen una serie de publicaciones y experiencia con estas patologías en LA. Un número considerable de publicaciones y casos con vasculitis primarias se han informado en Colombia en los recientes años, incluyendo la reciente descripción de la variante nodular de la vasculitis cutánea. La arteritis de Takayasu fue la variante más reportada del promedio de vasculitis, al igual que en Brasil y México. En contraposición a los hallazgos realizados en Brasil, Colombia y Mexico, las vasculitis asociadas a ANCA fueron la forma más informada en países como Chile y Perú. La mayoría de casos informados en LA provienen de México, siendo Colombia el segundo país en frecuencia. Es posible que exista más información pero no la conocemos, por no estar publicada. No existen estudios de incidencia y prevalencia. A escala mundial solo existen estudios de incidencia de las vasculitis primarias, y solo se han realizado estudios de incidencia y prevalencia en la granulomatosis de Wegener.

Purpose: primary vasculitis occurs with variable expression in individual patients and regions, and variable frequency throughout the world. Their overall incidence has been calculated to be 40 cases per million populations. We sought to describe the frequency of vasculitis in Colombia and compare it with vasculitis reported from other countries of Latin America (LA). Methods: review of available published literature on vasculitis in LA from 1945 to 2007 in OLD Medline, Pub Med, BIREME, SciELO Colombia, LILACS, FEPAFEN, including publications in English, Spanish and Portuguese. The literature included published information from San Juan de Dios hospital, Bogota, Colombia, and unpublished cases submitted directly to the authors. We calculated the percentage of all cases which are reported from Colombia. Results: we identified 857 cases of primary vasculitis in Colombia. Takayasu arteritis was the most common vasculitis in 13.3% (114 cases) followed by Buerger's disease in 11.2% (96 cases), primary cutaneous vasculitis and polyarteritis nodosa in a 10% (86 cases) each. In children, the vasculitis was more frequent in Henoch Schonlein purpura in 24% (206 cases). In Latin America, 177 articles were published in 1605 reported cases. It showed increased presence of Takayasu's arteritis in Mexico and Brazil, and microscopic poliangeiitis in Peru and Chile. Conclusion: while the majority of publications on primary vasculitis are from Europe and North America, there is a substantial literature and experience with these disorders in LA. A considerable number of publications and cases have emerged from Colombia in recent years, including case descriptions of a recently described variant of nodular cutaneous vasculitis. Takayasu arteritis was the most frequently reported form of primary vasculitis overall, and also from Brazil and Mexico. However, ANCA related vasculitis were the most commonly reported forms in Chile and Peru instead. The greatest numbers of cases were reported from Mexico, the LA's most populous country, with Colombia a close second.
