Our results showed a significant association between hyperuricemia and metabolic syndrome in low-income young adults in Mexico. DR is associated with estimated risk of CVD in type 2 diabetic patients.

Background: Hyperuricemia leads to insulin resistance, whereas insulin resistance decreases renal excretion of uric acid. The aim of this study was to evaluate whether there is a correlation between serum uric acid levels with homeostatic model assessment (HOMA) 1 in nondiabetic patients. Methods: We evaluated 88 nondiabetic patients, in whom uric acid levels were measured, in all of them HOMA of β-cell function (HOMA 1B) and HOMA of insulin resistance (HOMA 1IR) scores were performed. Uric acid and the HOMA 1 values were correlated using the Pearson coefficient. Results: We did not find any correlation between uric acid levels with both HOMA 1B (r = 0.102, p = 0.343), nor with HOMA 1IR (r = 0.158, p = 0.117). When patients were analyzed by sex, we found a significant correlation with HOMA 1IR (0.278, p = 0.01), but not with HOMA 1B (0.138, p = 0.257) in women. We found a correlation with HOMA 1B in men (r = 0.37, p = 0.044), but not with HOMA 1IR: 0.203, p = 0.283. The analysis performed based on body mass index did not show correlation in the patients with normal weight, (HOMA 1B r = 0.08, p = 0.5, HOMA 1IR = 0.034, p = 0.793), nor in the patients who were overweight (HOMA 1B: r = 0.05, p = 0.76, HOMA 1IR r = 0.145, p = 0.43). However, a significant correlation between uricemia with both HOMA 1B (0.559, p < 0.001), and HOMA 1IR (0.326, p < 0.05), was observed in obese patients. Conclusion: Our results suggest that serum uric acid levels seem to be associated with insulin resistance in women, and in obese patients, but not in nonobese men. Uric acid also modifies β-cell function in men and in obese patients.

Hyperuricemia leads to endothelial dysfunction and insulin resistance, and has been associated with diseases such as hypertension. Antihypertensive drugs modify serum uric acid levels, however, few data are available about their combinations on uricemia. In this study we evaluate the effect of two combinations of losartan, with amlodipine or with hydrochlorothiazide, on serum uric acid levels in hypertensive patients. Methods: A total of 60 hypertensive patients were randomized in two groups; group LA received losartan/amlodipine (100/5 mg) once a day, whereas LH group received losartan hydrochlorothiazide (100/12.5 mg) once a day for 3 months. In both groups serum uric acid levels were measured at the beginning and end of the study. Patients were evaluated monthly for blood pressure (BP) and adverse events. Statistical analysis was performed with a two-way analysis of variance (ANOVA) for repeated measures. Results: All patients experienced a significant reduction of BP to the same extent (LA 155/94 to 123/79, LH 157/92 to 124/78 mmHg, p > 0.05). In the LA group, serum uric acid decreased from 6.5 ± 1.6 to 4.6 ± 1.3 mg/ml (p = 0.0001), whereas in the LH group there was a nonsignificant increase from 5.82 ± 1.4 to 5.85 ± 1.5 mg/ml, (p = 0.936). When both groups were compared, we found a significant reduction (p < 0.00013) on serum uric acid levels in the LA group. Conclusions: Both combinations decrease BP values to the same extent, however, LA combination showed a reduction on serum uric acid levels, which may contribute to a reduction in the metabolic risk in hypertensive patients.

Prehypertensive patients had lower ABI and higher prevalence of peripheral artery disease when compared with normotensive subjects; this fact increases their cardiovascular risk. ABI must be included in global evaluation of prehypertensive subjects.

Valor del índice proteína C reactiva/albúmina en el diagnóstico de sepsis Resumen ANTECEDENTES: La sepsis es una de las principales causas de morbilidad y mortalidad en todo el mundo, en esta enfermedad el efecto de la respuesta inflamatoria puede empeorar el pronóstico del paciente. OBJETIVO: Averiguar si existe correlación entre el índice proteína C reactiva (PCR)/albúmina y las escalas SOFA y qSOFA a fin de establecer su utilidad como herramienta diagnóstica. MATERIAL Y MÉTODO: Estudio transversal analítico, realizado de julio de 2016 a junio de 2017 en el Servicio de Urgencias del Hospital General Xoco, SEDESA. Se incluyeron pacientes en quienes se estableció diagnóstico de sepsis mediante las escalas SOFA y qSOFA en quienes se determinó el índice PCR/albúmina, posteriormente se procedió a buscar correlación entre estas mediciones. RESULTADOS: Se incluyeron 30 pacientes. No se observó correlación entre los puntajes qSOFA (p = 0.79) y SOFA (p = 0.40) con el índice PCR/albúmina. El índice PCR/albúmina fue menor en el sexo femenino (p = 0.03). Se encontró una relación estadísticamente significativa de la muerte hospitalaria con un índice PCR/albúmina menor (p = 0.05). Otras variables que se correlacionaron con la muerte fueron la edad (p = 0.01) y la escala SOFA (p = 0.02). CONCLUSIONES: No existe correlación significativa entre el índice PCR/albúmina y los puntajes qSOFA y SOFA en el diagnóstico de sepsis. Se encontró un índice PCR/albúmina menor en los pacientes del sexo femenino y que tuvieron muerte hospitalaria. Otras variables que se correlacionaron con la muerte fueron la edad y el puntaje SOFA.

Background: Cystatin C has been shown to be more sensitive for the early detection of renal dysfunction compared to creatinine levels, reflecting better the glomerular filtration rate (GFR). This study attempted to demonstrate the relationship of cystatin C with GFR assessed by CKD-EPI and MDRD in patients with decompensated chronic liver failure secondary to alcoholism. Methods: In this cross-sectional analytical study, we included 30 patients from the General Hospitals of Xoco and Tláhuac from Mexico City´s Health Department. Laboratory determinations were made, and the severity scale and GFR were estimated. Statistical analysis was performed using SPSS 20 and STATA program. Results: We found a negative correlation between cystatin C, CKD-EPI (p = 0.0002) and MDRD (p = 0.0002), and a positive correlation with creatinine levels (p = 0.0007). Conclusions: There was a positive correlation between cystatin C and GFR determined by CKD-EPI / MDRD in patients with chronic liver failure secondary to alcoholism. (Hosp Med
