ABSTRACT
The guinea pig in Ecuador is synonymous with our ancestral gastronomy and cultural tradition, but because of the diet rich in L-canavanine (alfalfa) that they receive; could limit its consumption in patients with primary immune thrombocytopenia (ITP). Ingestion of alfalfa in humans can cause kidney failure and lupus-like syndrome. The John Hopkins Lupus Center recommends avoiding it in the diet of patients with Systemic Lupus Erythematosus (SLE), as it aggravates inflammation by stimulating immune activity (flares). We present two cases of patients with ITP linked to guinea pig ingestion. It is probable
El cuy en el Ecuador es sinónimo de nuestra gastronomía ancestral y de tradición cultural, pero por la alimentación rica en L-canavanina (alfalfa) que reciben; podría limitar su consumo en pacientes con trombocitopenia inmune primaria (PTI). La ingesta de alfalfa en humanos puede propiciar insuficiencia renal y síndrome lupus-like. El centro de Lupus John Hopkins recomiendan evitarla en la dieta de los pacientes con Lupus Eritematoso Sistémico (LES), al agravar la inflamación por estimulación de la actividad inmune (flares). Presentamos dos casos de pacientes con PTI vinculados con la ingesta de cuy. ¿Es probable?

OBJETIVO: Determinar si existe asociación entre los niveles séricos de vitamina D y el índice de actividad de la enfermedad en pacientes con artritis reumatoide (AR). METODOLOGÍA: Estudio transversal, analítico, retrospectivo realizado en el Hospital Luis Vernaza y el Centro de Reumatología y Rehabilitación. Se incluyó a pacientes entre 18 a 75 años con diagnóstico de AR según los criterios de clasificación 2010 y examen 25-hidroxivitamina D en los últimos 3 meses. La actividad de la enfermedad se evaluó con el 28-joint Desease Activity Score (DAS28) y la proteína C reactiva (PCR) como reactante de fase aguda. Para establecer asociación entre las variables se realizó por el coeficiente de correlación de Spearman. RESULTADOS: Se estudió a un total de 100 pacientes con AR. La media de vitamina D fue de 32,9 ± 11,5ng/ml, el 45% presentó insuficiencia de 25(OH)D y el 55% niveles normales; no se hallaron valores deficientes de vitamina D. De acuerdo con el DAS28-PCR, los pacientes en baja, moderada y alta actividad tuvieron una media de vitamina D de 30,4 ± 10,7, 31,9 ± 10,7 y 31,8 ±12,1 ng/ml, respectivamente. La actividad de la enfermedad y el nivel sérico de vitamina D no se correlacionaron significativamente (p = 0,60). CONCLUSIONES: En nuestro grupo de pacientes con AR no hubo correlación estadísticamente significativa entre los niveles de vitamina D y la actividad de la enfermedad; tampoco se asociaron otras variables determinantes a los niveles de vitamina D
OBJECTIVE: To determine whether there is an association between serum vitamin D levels and the Disease Activity Index in patients with rheumatoid arthritis (RA). METHODOLOGY: An analytical, retrospective, cross-sectional study was performed at the Hospital Luis Vernaza and Center for Rheumatology and Rehabilitation. We included 18 to 75-year-old patients with a diagnosis of RA according to the 2010 classification criteria, and with a 25-hydroxyvitamin D (25 [OH] D) test within the last 3 months. The activity of the disease was assessed with the 28-joint Disease Activity Score (DAS28) and C-reactive protein (CRP) as an acute-phase reactant. Spearman's rank correlation coefficient was used to establish association between the variables. RESULTS: A total of 100 RA patients were studied. The mean vitamin D levels were 32.9 ± 11.5 ng/mL. In all, 45% showed insufficient 25 (OH) D and 55% had normal levels; no deficient vitamin D values were found. According to the DAS28-CRP, patients with low, moderate and high activity had an average vitamin D level of 30.4 ± 10.7, 31.9 ± 10.7, and 31.8 ± 12.1 ng/mL, respectively. There were no significant correlations between the disease activity and the serum vitamin D level (P=.60). CONCLUSION: In our group of RA patients, there was no statistically significant correlation between the levels of vitamin D and the activity of the disease, nor were other determining variables associated with vitamin D levels
