Background: Therapeutic drug monitoring (TDM) involves the measurement of serum drug concentrations to optimize pharmacotherapy. Traditionally, blood pressure measurements alone, and not TDM, have been used to evaluate the antihypertensive drug response. However, approximately 50% of hypertensive patients treated with lifestyle changes and antihypertensive drugs fail to achieve blood pressure control. Serum drug concentration measurements could be useful to select the optimal drugs in adjusted doses and to identify nonadherence. Implementation of TDM in clinical routine for antihypertensive drugs depends on established serum reference ranges.

Methods: Commonly used antihypertensive drugs were identified based on prescription data. The authors performed a review of authoritative literature on reported serum drug concentrations and calculated expected concentrations from previously reported pharmacokinetic parameters with commonly prescribed daily doses. Finally, serum drug concentrations in samples from patients undergoing antihypertensive treatment were measured.

Results: Serum reference ranges for 24 frequently used antihypertensive drugs were established based on results from 3 approaches.

Conclusions: Serum drug concentration measurements, interpreted in light of the established reference ranges, together with blood pressure measurements and other clinical data, may help identify nonadherent patients and tailor individual antihypertensive treatment when deviant drug responses appear in line with the concept of personalized medicine.

Background: Guidelines recognized dual combination in initial antihypertensive therapy. Studies found that low-dose quadruple combination were superior to monotherapy. However, whether low-dose quadruple therapy is better than dual combination is unknown.

Purpose: Observational studies have suggested negative associations between maternal 25-hydroxyvitamin D (25(OH)D) status and risk of hypertensive disorders of pregnancy [pregnancy-induced hypertension (PIH) and preeclampsia (PET)]. Data from intervention studies are limited. We hypothesised that vitamin D supplementation would lower maternal blood pressure (BP) during pregnancy and reduce the incidence of hypertensive disorders of pregnancy.

Rationale: Previous studies evaluating the effect of continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) on blood pressure (BP) showed variable results. Moreover, several studies recruited patients with normal or controlled BP, and compliance to antihypertensive drugs was not monitored. In addition, very few studies investigated central BP in this scenario.

Economic impact of initial glaucoma treatment with selective laser trabeculoplasty on the Brazilian Public Health System.

Arq Bras Oftalmol

January 2025

Discipline of Health Management and Economics, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.

Purpose: To evaluate the economic impact of the following initial treatment scenarios for glaucoma on the Brazilian Public Health System (SUS): (1) traditional continuous instillation of hypotensive eye drops and (2) single session of selective laser trabeculoplasty.

Methods: Economic impact was analyzed in three scenarios, from the least to the most conservative, for a hypothetical cohort of 5,000 individuals with open-angle glaucoma. Thereafter, projections were made on the basis of a glaucoma prevalence of 3% in the 2021 Brazilian population size.

December 2024

Drs. Lu, Du, Zhao, and Fan and Lingbo Bi, Chaofan Wang, and Yunbu Ding are from the Department of Dermatology, The First Affiliated Hospital of Nanjing Medical University, China. Yige Fan is from the Mayo Clinic, Rochester, Minnesota.

Article Synopsis
  • The study reviewed 133 pediatric patients over 14 years to understand the prevalence and effects of androgenetic alopecia (AGA), with symptoms appearing as early as age 10.
  • Factors such as BMI, family history, comorbidities, and hair loss patterns were examined, revealing differences in trichoscopic outcomes between sexes and age groups.
  • The research emphasizes the need for personalized treatment plans for AGA in children, suggesting the use of topical minoxidil while ensuring close monitoring and encouraging adherence to medication and follow-ups for better results.
