Long-lasting reduction of blood pressure by electroacupuncture in patients with hypertension: Randomized controlled trial

© Mary Ann Liebert, Inc. 2015. Background: Acupuncture at specific acupoints has experimentally been found to reduce chronically elevated blood pressure. Objective: To examine effectiveness of electroacupuncture (EA) at select acupoints to reduce systolic blood pressure (SBP) and diastolic blood pressures (DBP) in hypertensive patients. Design: Two-arm parallel study. Patients: Sixty-five hypertensive patients not receiving medication were assigned randomly to one of the two acupuncture intervention (33 versus 32 patients). Intervention: Patients were assessed with 24-hour ambulatory blood pressure monitoring. They were treated with 30-minutes of EA at PC 5-6+ST 36-37 or LI 6-7+GB 37-39 once weekly for 8 weeks. Four acupuncturists provided single-blinded treatment. Main outcome measures: Primary outcomes measuring effectiveness of EA were peak and average SBP and DBP. Secondary outcomes examined underlying mechanisms of acupuncture with plasma norepinephrine, renin, and aldosterone before and after 8 weeks of treatment. Outcomes were obtained by double-blinded evaluation. Results: After 8 weeks, 33 patients treated with EA at PC 5-6+ST 36-37 had decreased peak and average SBP and DBP, compared with 32 patients treated with EA at LI 6-7+GB 37-39 control acupoints. Changes in blood pressures significantly differed between the two patient groups. In 14 patients, a long-lasting blood pressure-lowering acupuncture effect was observed for an additional 4 weeks of EA at PC 5-6+ST 36-37. After treatment, the plasma concentration of norepinephrine, which was initially elevated, was decreased by 41%; likewise, renin was decreased by 67% and aldosterone by 22%. Conclusions: EA at select acupoints reduces blood pressure. Sympathetic and renin-aldosterone systems were likely related to the long-lasting EA actions

Mild to moderate increase of serum calcitonin levels only in presence of large medullary thyroid cancer deposits

Many open questions remain to be elucidated about the diagnosis, treatment and prognosis of medullary thyroid cancer (MTC). The Most intriguing concerns the outcome of MTC patients after surgery. Great importance is usually given to serum calcitonin (Ct) and carcinoembryonic (CEA) levels. It is commonly believed that the higher are the levels of these tumor markers and their kinetics (double time and velocity of markers levels) the worst is the prognosis. However, this is not the rule, as there are huge MTC metastatic deposits characterized by low serum Ct and CEA levels, and this condition is not closely related to the outcome of the disease during post-surgical follow-up. A series is reported here of patients who have these characteristics, as well as a description of their prognosis and clinical outcome. (C) 2015 Elsevier Espana, S.L.U. and SEMNIM. All rights reserve
