RESUMO

El tratamiento con insulina puede ser necesario en la diabetes tipo 2, dado que muchos pacientes, con el tiempo, no consiguen alcanzar o mantener los objetivos glucémicos para prevenir las complicaciones crónicas asociadas a la hiperglucemia sostenida. Inicialmente, la adición de insulina basal al tratamiento previo con agentes orales suele ser la pauta más habitual. Esta estrategia se basa en el control óptimo de la glucemia en ayunas. Sin embargo, un porcentaje significativo de pacientes no consiguen alcanzar o mantener el objetivo de HbA1c <=7%, debido a que presentan elevaciones excesivas de la glucemia posprandial. En consecuencia, el paso siguiente en la intensificación deltratamiento podría ser la adición de una dosis única de insulina prandial antes de la comida que provoca la mayor excursión posprandial (estrategia basal plus), manteniendo el tratamiento previo con insulina basal y agentes orales. Este régimen ha demostrado ser sencillo, eficaz y adecuado para un gran número de pacientes. Además, en caso necesario, facilita la introducción progresiva de inyecciones adicionales de insulina prandial hasta una estrategia bolo basal. En este artículo se resumen las recomendaciones de un grupo de trabajo multidisciplinar para una adecuada implementación de la estrategia basal plus en la práctica clínica habitual (AU)


Insulin treatment may be necessary in type 2 diabetes, because many patients are not able overthe time to achieve or maintain glycemic targets to prevent chronic complications associated to sustained hyperglycemia. Initially, addition of basal insulin to previous treatment with oral agentsis the most commonly used regimen. This strategy is based on optimal control of fasting plasma glucose. However, a significant proportion of patients does not achieve or maintain HbA1c target <=7%, because they show excessive postprandial glucose values. Therefore, the next step for intensification of treatment might be the addition of a single dose of prandial insulin before the main meal, which is associated with the greatest postprandial glucose excursion (basal plus strategy), maintaining previous treatment with basal insulin and oral agents. This regimen has demonstrated to be easy to use, effective and appropriate for many patients. Furthermore, if necessary, it makes easier progressive introduction of additional injections of prandial insulin until the basal bolus strategy. In this manuscript, recommendations from a multidisciplinary working group are summarized for an adequate implementation of the basal plus strategy in the routine clinical practice (AU)

RESUMO

Una mujer de 30 años ingresó en el hospital en coma profundo sin causa aparente ni duración conocida. Los estudios posteriores revelaron un hiperinsulinismo endógeno con hipoglucemia como origen del cuadro. La cateterización selectiva arterial de las ramas del tronco celíaco con inyección de calcio y recogida de muestras en vena hepática permitió localizar un insulinoma en la cabeza pancreática, no evidente en ninguna de las otras exploraciones practicadas. La cirugía subsiguiente fue curativa, pero quedaron secuelas neurológicas con lesiones groseras evidentes en la RMN. Aunque infrecuente, la posibilidad de una hipoglucemia debida a un insulinoma debe tenerse presente en el diagnóstico diferencial de un paciente en coma sin etiología evidente. El debut de un insulinoma con un único episodio de coma puede tener un efecto devastador a nivel cerebral, con importantes secuelas neurológicas (AU)

RESUMO

OBJECTIVE: To know the prevalence of adrenal insufficiency (AI) in our patients with acquired immunodeficiency syndrome (AIDS) and to compare the clinical manifestations with those reported in previous series in the literature. PATIENTS AND METHODS: Retrospective study with review of clinical records of patients with AIDS diagnosed of AI (plasma cortisol after synthetic ACTH < 18 micrograms/dl) in our hospital for a period of 6 and a half years. RESULTS: Eleven out of 65 patients (17%) with the hormonal study performed were diagnosed of AI. The prevalence of AI in our patients with AIDS was 1.66%. The response of plasma cortisol to synthetic ACTH was abnormal in the 11 patients (mean increase: 1.89 micrograms/dl). Nine out of the 11 patients had a decreased basal plasma cortisol level (mean: 4.75 micrograms/dl). Basal plasma ACTH levels were increased (mean: 638.9 pg/ml) in seven out of nine patients. Patients were severely immunosuppressed (mean CD4: 21/microliter). While the clinical course was subacute (mean: 5.1 weeks), nine out of the eleven patients developed an adrenal crisis which required emergency therapy. Ten patients had an opportunist infection--M. tuberculosis (3), M. avium-intracellulare (3), Cytomegalovirus (3), histoplasmosis (1)--which could involve the adrenal glands in ten patients. All patients responded to treatment but their mean survival was 5.6 weeks. CONCLUSIONS: Although the prevalence of AI in our patients with AIDS was low (1.66%), it is important to be aware of the disease and to order a basal plasma cortisol value after synthetic ACTH, as treatment improves the life quality of patients if AI is confirmed, despite a short survival time.
