[Primary care evaluation of the hypertensive patient management in specialized care after derivation (DERIVA-2 Study)]. / Valoración desde atención primaria del manejo del hipertenso en atención especializada (estudio DERIVA-DOS).

INTRODUCTION: To know the opinion/evaluation of the primary care physicians (PCPH) of the received information about patients that were attended in specialized care (SC). DESIGN: Cross-sectional study. LOCATION: Performed nationwide in primary care centers. PARTICIPANTS: Researchers from the primary care network. METHODS: We used the SEH-LELHA derivation criteria guidelines, plus an ad hoc survey that included demographic and anthropometric data, blood pressure levels, and the main reason for derivation to SC at the baseline and final (post-derivation) visit. In addition, time deployed for the study of every patient, changes in diagnosis and treatment, type of follow-up, issues throughout the derivation process and assessment of the medical referred to the PCPH were evaluated. RESULTS: With participation of 578 researchers from primary, the study included 1715 patients aged 60.7±13.3years, 62.7% male. Patients were taking 2.3±1.2 (range 0-10) antihypertensive drugs pre-referral and 2.5±1.2 (0-9) after derivation. Blood pressure levels changed from 166±21.6 /97.7±12.6mmHg to 143±14.4 /85.5±10.5mmHg. The number of controlled patients (BP<140 and <90mmHg) increased from 5.8% to 32.2%. Time between pre- and post-derivation visit was 72±64days (median 57days, IQ26-99). The PCPH received a medical report in 80.3% of cases, 76.9% with an explanation of the results of the complementary tests, 75.8% with additional information or a reasoning of treatment and in 71% of cases information about the patient future management. 63% of PCPH were fully agreed with the management of the specialist, 29% agree and 2% strongly disagree. The derivation was evaluated as effective or very effective in 86% of patients and no effective in 9%. CONCLUSIONS: Communication between AE and SC in HTA is valued satisfactorily by MAP. However there is still room for improvement in the process.

[Thyroid dysfunction in patients with advanced renal cell carcinoma treated with sunitinib: a multifactorial issue]. / Disfunción tiroidea en los pacientes con carcinoma de células renales avanzado en tratamiento con sunitinib: un problema multifactorial.

OBJECTIVE: Several studies have reported the substantial prevalence of sunitinib-induced thyroid dysfunction. However, the underlying mechanism and the benefit of thyroid hormone replacement therapy remain to be determined. To evaluate the effect of sunitinib on thyroid function, we carried out a descriptive study in patients with advanced renal cell carcinoma. PATIENTS AND METHODS: A total of 24 patients treated by sunitinib between 2006 and 2008 at Hospital Clínico San Carlos were included. The data were collected retrospectively and analyzed with SPSS 15.0. RESULTS: Treatment duration was 30 weeks (18-42) [median (IQR)]. Five patients (20.8%) developed subclinical hypothyroidism and three (12.5%) developed overt hypothyroidism. The number of weeks needed to observe an increase in thyroid-stimulating hormone (TSH) values in these patients was 15 (6-20) [median (IQR)]. TSH levels were below the normal range in five patients (20.8%) before or during the treatment period, but the diagnosis of subclinical hyperthyroidism could not be established because of concomitant factors. Fourteen patients (58.3%) showed sunitinib adverse events, but these were not related to the development of hypothyroidism (p=0.388). CONCLUSIONS: Because of the high prevalence of sunitinib-induced hypothyroidism, thyroid function should be systematically monitored in patients with renal cell carcinoma treated with this drug. However, several pathophysiological and pharmacological factors may interfere with monitoring. Consequently, it might be useful to determine not only TSH and free T4 but also free T3 and, ideally, reverse T3. Evidence-based recommendations to manage hypothyroidism in oncology patients are not available at present.
