RESUMO
Eltrombopag is a second-line treatment in primary immune thrombocytopenia (ITP). However, its role in secondary ITP is unknown. We evaluated the efficacy and safety of eltrombopag in secondary ITP in daily clinical practice. Eighty-seven secondary ITP patients (46 with ITP secondary to autoimmune syndromes, 23 with ITP secondary to a neoplastic disease subtype: lymphoproliferative disorders [LPDs] and 18 with ITP secondary to viral infections) who had been treated with eltrombopag were retrospectively evaluated. Forty-four patients (38%) had a platelet response, including 40 (35%) with complete responses. Median time to platelet response was 15 days (95% confidence interval, 7-28 days), and was longer in the LPD-ITP group. Platelet response rate was significantly lower in the LPD-ITP than in other groups. However, having achieved response, there were no significant differences between the durable response of the groups. Forty-three patients (49·4%) experienced adverse events (mainly grade 1-2), the commonest being hepatobiliary laboratory abnormalities. There were 10 deaths in this case series, all of which were related to pre-existing medical conditions. In routine clinical practice, eltrombopag is effective and well-tolerated in unselected patients with ITP secondary to both immune and infectious disorders. However, the response rate in LPD-ITP is low.

INTRODUCTION: Several studies warn that overweight and obesity have become an epidemic with severe consequences in the population's health. The objetive of the present study is to estimate the prevalence of overweight and obesity in Castile and Leon in a sample of children at 6, 11 and 14 years of age, to describe its evolution and its association with life habits and antecedents. MATERIAL AND METHODS: Observational study, retrospective cohort, performed by the pediatricians of the Health Sentinel Network. The study is part of a joint Project with the National Research Center on Human Evolution (CENIEH) in Burgos to know the pattern of growth and development of the child population of Castile and Leon. In 2012, a health examination and a retrospective collection were carried out based on the clinical history of a simple of 326 children, from the cohort was born in 1998. RESULTS: Following the WHO references, at age 14 there was 25.3% of boys and 18.5% of girls with overweight. Obesity was estimated to affect the 8.2% and 4.8% of them respectively. At 11 years of age there was the maximum of overweight in girls and of obesity in boys. At the urban-non urban environment, quantity and quality of sleep and the parents' BMI have been some of the associated factors to weight level of the children. DISCUSSION: In Castile and Leon, as in other populations of our environment, there is a severe problema of overweight and obesity. For their control it is necesary to deepen understanding of lifestyles and antecedents related to the birth as well as to calculate the growth rate in the pediatric age.

Eltrombopag is safe and effective in primary chronic ITP. However, lack of clinical trials avoids a clear demonstration of its utility in newly diagnosed and persistent ITP. Our aim here is to report Spanish results for this type of patients. We retrospectively evaluated 220 adult primary ITP patients. According to standard definition, patients were allocated to newly diagnosed (n = 30), persistent (n = 30), and chronic (n = 160) ITP. Groups were homogenous regarding most relevant parameters. 180 (90%) of 220 patients achieved a platelet response (R) with 167 (75.9%) complete responses (CR) after a 15-month follow-up. No statistical significant differences among groups but a trend towards a greater efficacy in newly diagnosed ITP were observed (93.3% of responses with 86.7% of CR). Efficacy in persistent ITP (83.3% of responses with 80.0% of CR) and chronic ITP (79.4% of responses with 73.1% of CR) was similar. 70 patients (31.8%) experienced adverse events. 15 of them were grade 3-4. Most common adverse effects were headache and hepatobiliary laboratory abnormalities (HBLAs). One persistent ITP had a venous thrombosis and one chronic ITP had grade II myelofibrosis. We consider Eltrombopag use for the early stage ITP as effective and safe as it is in chronic ITP.
