Ítem Lupus Nephritis in Colombians: Contrasts and Comparisons with Other Populations(Humana Press Inc, 2011-06-01) Cañas Dávila, Carlos AlbertoLupus nephritis (LN) is one of the most serious complications of systemic lupus erythematosus (SLE) since it is the major predictor of poor prognosis. The purpose of this study was to examine the clinical and immunological characteristics associated with LN development during the course of SLE in Colombians. Therefore, patients with SLE followed at five different referral centers in Medellin, Bogota, and Cali were included in this cross-sectional and multicenter study. Factors influencing LN were assessed by conditional logistic regression analysis, adjusting by gender, age at onset, duration of disease, and city of origin.Ítem Psychiatric manifestations in patients with dysautonomy associated with systemic lupus erythematosus(SAGE Publications, 2012-09-01) Bonilla Abadía, FabioThe psychiatric manifestations of three patients with systemic lupus erythematosus (SLE) and neuropathic dysautonomic processes are described. All patients had a severe form of SLE with neurological, renal, articular, pulmonary or haematological manifestations. All three have two types of psychiatric manifestations: (1) a chronic and progressive depression and (2) a complex dissociative disorder during the acute episodes of postural hypotension. A provocative test with SPECT with 99mTc-HmPAO to be done during the episode of orthostatic hypotension may contribute to clinical assessment of complex changes in cerebral regional perfusion.
