Concordancia diagnóstica entre siete criterios de síndrome metabólico en adultos con sobrepeso y obesidad

Objectives. The aim of this study was to determine the level of diagnostic concordance between seven definitions of metabolic syndrome (MS) in a group of overweight and obese adults. Materials and Methods. 350 subjects aged from 19 to 70 years were recruited for study from a clinic for overweight and obese subjects. The definitions of MS used were those given by the WHO (World Health Organization), EGIR (European Group for the Study of Insulin Resistance), NCEPATPIII (Adult Treatment Panel), AHA/NHLBI (American Heart Association), IDF (International Diabetes Federation), and JIS (Joint Interim Statement) as well as the Szabo criteria. Concordance between the definitions was calculated with the Kappa coefficient. Insulin resistance (IR) was assessed using the HOMA-IR index. Results. According to the Szabo, WHO, EGIR, NCEP-ATPIII, AHA/NHLBI, IDF, and JIS criteria, MS frequency was 74.3%, 42.0%, 46.8%, 56.0%, 52.9%, 58.6%, and 58.6%, respectively. The concordance between the Szabo and AHA/NHLBI criteria was 0.559, while the Kappa coefficient between the Szabo criteria and the rest of the guides (NCEP-ATPIII, IDF, and JIS) was from 0.612 to 0.657, respectively. The concordance of the WHO with the EGIR was 0.602, but it was between 0.358 and 0.422 with the other guidelines. IR was distributed similarly in all guidelines. Conclusions. There is a considerable concordance between the NCEP-ATPIII, IDF, and JIS guidelines and the Szabo criteria. The Szabo criteria could be an option for the active surveillance of MS in populations.Objetivos. El objetivo del presente estudio fue determinar el grado de concordancia diagnóstica entre siete definiciones de síndrome metabólico (SM) en un grupo de adultos con sobrepeso y obesos. Material y Métodos. Se estudiaron 350 sujetos con edades comprendidas entre 19 y 70 años que fueron reclutados consecutivamente de una consulta para sujetos con sobrepeso y obesidad. Se emplearon las definiciones de SM según OMS (Organización Mundial de la Salud), EGIR (Grupo Europeo para el estudio de la resistencia a la insulina), NCEP-ATPIII (Panel de Tratamiento de Adultos), AHA/NHLBI (Asociación Americana del Corazón), IDF (Federación Internacional de Diabetes), JIS (Declaración provisional conjunta), así como los criterios de Szabo. La concordancia entre las definiciones fue calculada con el coeficiente Kappa. La resistencia a la insulina (RI) fue evaluada mediante el índice HOMA. Resultados. Según los criterios de Szabo, OMS, EGIR, NCEP-ATPIII, AHA/NHLBI, IDF y la JIS, la frecuencia de SM fue del 74,3%, 42,0%, 46,8%, 56,0%, 52,9%, 58,6% y 58,6%, respectivamente. La concordancia entre los criterios de Szabo y la AHA/NHLBI fue de 0,559, mientras que el coeficiente kappa entre los criterios de Szabo, y el resto de las guías (NCEP-ATPIII, IDF, JIS) fue de 0,612 a 0,657, respectivamente. La concordancia de la OMS con las demás guías fue entre 0,358 y 0,422, pero con la EGIR la concordancia fue de 0,602. La RI se distribuyó de manera similar en todas las guías. Conclusiones. Existe una considerable concordancia entre las guías NCEP-ATPIII, IDF, JIS y el SM según criterios de Szabo. El SM según criterios de Szabo pudiera ser otra alternativa para la pesquisa activa del SM en poblaciones

An Exploratory Study of Itolizumab on the Preservation of Beta Cell Function in Adults with Recent-Onset Type 1 Diabetes

We conducted a phase I-IIa, randomized, monocentric, double-blind, placebo-controlled clinical trial to evaluate the safety and impact of the combination treatment of Itolizumab and insulin on preserving beta cell function in adults with recent-onset type 1 diabetes. Twelve patients were randomly assigned to three treatment groups, each receiving a different Itolizumab dose (0.4/0.8/1.6 mg/kg body weight, respectively) and a placebo group. All patients received concomitant intensive multiple-dose insulin therapy. Endogenous insulin secretion was assessed by the measurement of C-peptide during the mixed-meal tolerance test. No serious adverse events were reported. No changes in the total daily insulin doses, glycated hemoglobin levels, and stimulated C-peptide were observed between the Itolizumab and placebo groups at 52 weeks. A significant decrease in stimulated C-peptide was observed during the follow-up period (p = 0.012). One subject treated with 1.6 mg of Itolizumab showed a marked increase in the levels of stimulated C-peptide three years after completion of the trial. Taken together, this is the first study to demonstrate that combination treatment with Itolizumab and insulin is safe in humans and does not affect the residual function of beta cells up to 52 weeks. The findings from our study show preliminary evidence that high doses of Itolizumab could potentially arrest the loss of beta cell function in the long term. Further studies with a longer follow-up and larger numbers of patients are envisaged to assess the effect with high dose Itolizumab
