Antioxidant and associated capacities of Camu camu (Myrciaria dubia): a systematic review.

An aging population in the United States presents important challenges for patients and physicians. The presence of inflammation can contribute to an accelerated aging process, the increasing presence of comorbidities, oxidative stress, and an increased prevalence of chronic pain. As patient-centered care is embracing a multimodal, integrative approach to the management of disease, patients and physicians are increasingly looking to the potential contribution of natural products. Camu camu, a well-researched and innovative natural product, has the potential to contribute, possibly substantially, to this management paradigm. The key issue is to raise camu camu's visibility through increased emphasis on its robust evidentiary base and its various formulations, as well as making consumers, patients, and physicians more aware of its potential. A program to increase the visibility of camu camu can contribute substantially not only to the management of inflammatory conditions and its positive contribution to overall good health but also to its potential role in many disease states.

A cost-effectiveness analysis of sinecatechins in the treatment of external genital warts.

OBJECTIVE: To evaluate the cost-effectiveness and treatment-cost impact of sinecatechins (Veregen) as first-line therapy against its principal comparator, imiquimod (Aldara), in the treatment of external genital warts (EGWs). METHOD: A two-stage decision model is proposed to compare sinecatechins with its principal comparator, imiquimod, as a first-line topical therapy in the treatment of EGWs. The model utilizes estimates of sustained clearance from two pivotal sinecatechins trials and from a systematic literature review for imiquimod. Resource inputs are: (1) trial-based estimates of average drug utilization and (2) CPT (Current Procedural Terminology) codes describing anticipated office visits and utilization of second-line ablative procedures. The analysis considers: (1) comparative costs of achieving a successful outcome with sinecatechins versus imiquimod, and (2) comparative cost-consequences of sinecatechins versus imiquimod. As a modeled approach to evaluating comparative product effectiveness, the claims made reflect the structure of the model, which focuses on topical products as first-line therapy in EGW interventions and in its reliance on estimates of sustained clearance from pivotal randomized clinical trials (RCTs). Sustained clearance in this context being defined as the proportion of patients who report initial wart clearance over the RCT period corrected for subsequent recurrence. RESULTS: As first-line therapy, sinecatechins dominates imiquimod as a lower cost treatment with a higher sustained clearance rate (51.9 vs. 40.6%). First-line average cost of treatment with sinecatechins is $774 compared to imiquimod at $930. Cost per successful outcome with sinecatechins is $1,492, which is lower than $2,289 for imiquimod. Taking account of patients failing first-line therapy moving to a second-line ablative therapy yields an average cost of treatment for patients initiated to sinecatechins of $943 and $1,138 for those initiated to imiquimod. A sensitivity assessment confirmed the position of sinecatechins within the decision-model framework. CONCLUSION: Sinecatechins yields a lower cost of treatment compared to imiquimod in the treatment of EGW. It also offers cost savings to healthcare systems. This conclusion should be qualified by the limitations of the decision framework within which the assessment has been made. The model focuses on topical preparations as first-line therapies, with estimates of sustained clearance taken from pivotal RCTs. Treatment cost estimates are generated independently, but reflect current product and ancillary costs.

Patterns of treatment and resource utilization in the treatment of external genital warts in England and Wales.

Our objective was to identify patterns of treatment and resources used in achieving complete clearance of external genital warts (EGWs) A retrospective case note review was carried out at six genitourinary medicine (GUM) clinics in the UK. Case notes from 2366 patients presenting with EGWs were reviewed and 1200 patients with complete episodes of care were identified. Analysis showed that staff-applied therapy dominated treatment practice but there was considerable diversity in treatment modalities across study sites. The average number of visits was 5.71 visits for males: 6.25 visits for females but a substantial minority of patients attended significantly in excess of these averages. Approximately two-thirds of patients failed to achieve complete clearance of warts with their initial therapy. There is little consistency in treatment patterns of care for EGWs across the sites studied. Initial therapy choices are largely ineffective, requiring changes in treatment modality and multiple clinic visits. Increased utilization of patient-applied therapies might result in increased cost effectiveness.
