Clinical and metabolic profile of patients with latent autoimmune diabetes in adults in specialized care in Madrid. / Perfil clínico y metabólico de pacientes con diabetes tipo LADA atendidos en atención especializada en la comunidad de Madrid.

OBJECTIVE: To report the clinical characteristics of patients with latent autoimmune diabetes in adults (LADA), and to ascertain their metabolic control and associated chronic complications. METHODS: Patients with DM attending specialized medical care in Madrid who met the following criteria: age at diagnosis of DM >30years, initial insulin independence for at least 6months and positive GAD antibodies were enrolled. Clinical profiles, data on LADA diagnosis, associated autoimmunity, C-peptide levels, therapeutic regimen, metabolic control, and presence of chronic complications were analyzed. RESULTS: Number of patients; 193; 56% females. Family history of DM: 62%. Age at DM diagnosis: 49years. Delay in confirmation of LADA: 3.5years. Insulin-independence time: 12months. Baseline serum C-peptide levels: 0.66ng/ml. Basal-bolus regimen: 76.7%. Total daily dose: 35.1U/day, corresponding to 0.51U/Kg. With no associated oral antidiabetic drugs: 33.5%. Other autoimmune diseases: 57%. Fasting plasma glucose: 160.5mg/dL. HbA1c: 7.7%. BMI: 25.4kg/m2 (overweight, 31.5%; obesity, 8%). Blood pressure: 128/75. HDL cholesterol: 65mg/dL. LDL cholesterol: 96mg/dL. Triglycerides: 89mg/dL. Known chronic complications: 28%. CONCLUSIONS: Recognition of LADA may be delayed by several years. There is a heterogeneous pancreatic insulin reserve which is negative related to glycemic parameters. Most patients are poorly controlled despite intensive insulin therapy. They often have overweight, but have adequate control of BP and lipid profile and a low incidence of macrovascular complications.

Perfil clínico y metabólico de pacientes con diabetes tipo LADA atendidos en atención especializada en la comunidad de Madrid / Clinical and metabolic profile of patients with latent autoimmune diabetes in adults in specialized care in Madrid

Objetivo: Definir las características clínicas de los pacientes con diabetes autoinmune latente del adulto (LADA), conocer su control metabólico y las complicaciones crónicas asociadas que presentan. Métodos: Seleccionamos pacientes con DM seguidos en las consultas de endocrinología de hospitales públicos de la Comunidad de Madrid que reunían los siguientes criterios: edad al diagnóstico de DM >30años, independencia inicial de insulina durante al menos 6meses y positividad de anticuerpos antiGAD. Analizamos datos clínicos relativos al diagnóstico de LADA, autoinmunidad asociada, niveles de péptidoC, pauta terapéutica, control metabólico y presencia de complicaciones crónicas. Resultados: Número de pacientes: 193. Mujeres: 56%. Antecedentes familiares de DM: 62%. Edad al diagnóstico de DM: 49años. Retraso en confirmación LADA: 3,5años. Tiempo de insulino-independencia: 12meses. PéptidoC basal suero: 0,66ng/ml (0,22nmol/l). Pauta de insulina basal-bolus: 76,7%. Dosis total diaria: 35,1U/día, correspondiente a 0,51U/kg. Sin fármacos orales asociados: 33,5%. Presencia de otras patologías autoinmunes: 57%. Glucemia en ayunas: 160,5mg/dl (8,91mmol/l). HbA1c: 7,7%. IMC: 25,4kg/m2 (sobrepeso: 31,5%; obesidad: 8%). Presión arterial: 128/75. Colesterol HDL: 65mg/dl (16,9mmol/l). Colesterol LDL: 96mg/dl (24,96mmol/l). Triglicéridos: 89mg/dl (1,01mmol/l). Complicaciones crónicas: 28%; microangiopatía: 23,1%; macroangiopatía: 4,9%. Conclusiones: El reconocimiento de LADA puede retrasarse varios años. La reserva pancreática de insulina de los pacientes es heterogénea y el grado medio de control glucémico deficiente a pesar de utilizar mayoritariamente insulinoterapia intensiva. Con frecuencia presentan sobrepeso, aunque tienen un control adecuado de la presión arterial y perfil lipídico y baja incidencia de complicaciones macroangiopáticas (AU)
