Topical Applications

Introduction. Topical applications of hyaluronic acid (HA)–containing formulations, based on the complex and vital role of HA in all stages of the wound-healing process, are routinely used with standard therapy to promote faster healing of chronic wounds. However, evidence to guide clinical decisions on the use of topical HA in the healing of vascular leg ulcers is limited. Objective. This study compared the efficacy and safety of topical application of a hyaluronic acid cream vs a neutral comparator (identical cream without HA) in treating subjects with chronic leg ulcers of vascular origin. Materials and Methods. This was a prospective, multicenter double-blind randomized controlled trial. One hundred sixty-eight subjects with chronic leg ulcers of venous or mixed (venous and arterial) origin were randomized to receive either topical applications of 0.2% HA cream or neutral comparator cream for a maximum of 20 weeks. The primary efficacy endpoint was complete ulcer healing (100% reepithelialization of the wound area centrally assessed at 20 weeks or before and confirmed 3 weeks later). In both groups, topical treatment was associated with standard therapy (ulcer cleansing and optimized compression). Results. The proportion of subjects with centrally assessed complete healing of the target ulcer that was confirmed 3 weeks later (primary efficacy endpoint) was substantially higher in the HA cream group (31.3%) than in the neutral cream group (14.8%; P =.009). Results in the full analysis, per protocol, and as assessed by the investigator were consistent with primary results. No significant difference in treatment effect was observed when subjects were stratified according to baseline ulcer size (≤20 cm2 or >20 cm2) regardless of topical treatment. Safety and tolerability were comparable between treatments. Conclusions. Treatment of subjects with chronic leg ulcers of venous or mixed origin with HA cream is safe, well tolerated, and results in a higher rate of healing than a neutral comparator cream.

AbstractPlacental-derived tissues are a known source of anti-inflammatory and immune modulating factors. Published pilot data on amniotic suspension allograft (ASA) for the treatment of osteoarthritis (OA) demonstrated safety and trends for improved pain and function. A multicenter randomized controlled trial was designed to evaluate the efficacy of symptom modulation with ASA compared with saline and hyaluronic acid (HA) in subjects with knee OA. A total of 200 subjects were randomized 1:1:1 to ASA, HA, or saline, with subjects blinded to their allocation. Changes from baseline of patient-reported outcomes (PROs)—EQ-5D-5L, Knee Osteoarthritis Outcome Score (KOOS), visual analog scale (VAS), Tegner, and Single Assessment Numerical Evaluation (SANE)—were compared between groups. Patients reporting unacceptable pain at 3 months were considered treatment failures and withdrawn from the study. Statistical analysis was completed by comparing changes in PROs from baseline to 3 and 6 months for all groups. Comparison of demographics between treatment groups showed no significant differences between groups. Patients reporting unacceptable pain at 3 months in each group were ASA (13.2%), HA (68.8%), and saline (75%). Patients receiving ASA demonstrated significantly greater improvements from baseline for overall pain (VAS), KOOS pain, and KOOS-activities of daily living scores compared with those in the HA group (3 months) and both groups (6 months). ASA patients had significantly greater improvements in KOOS symptom scores compared with HA and saline at 3 and 6 months, respectively. OMERACT-OARSI responder rates for ASA, HA, and saline groups were 69.1, 39.1, and 42.6%, respectively (p = 0.0007). Subjects receiving ASA treatment showed greater improvements in PROs and fewer patients reported unacceptable pain compared with HA and saline. The evidence presented in this Level I Randomized Controlled Trial suggests that ASA injection is an effective treatment for the nonoperative management of symptomatic knee OA.

Abstract Background: In recent years, more and more studies revealed that liver fibrosis progression could happen at early stage in chronic hepatitis B (CHB) patients. However, there is no anti-fibrotic agent available at present in modern medicine.He-He-Shu-YangParticles (HHSYP) and Anluohuaxian Pills (AHP)are two commonly used Traditional Chinese Medicine (TCM) agents for liver fibrosis, but there is no data of them for early liver fibrosis(F1 or F2) in multicenter, randomized controlled trial. Therefore, the aim of this study is to evaluate efficacy and safety ofHHSYP plus AHP for early liver fibrosis in CHB patients. Methods/design: For the 72-week randomized controlled study, 480 CHB patients with early liver fibrosis are randomly assigned at a 2:1 ratio to two groups: the intervention group and the placebo group. The intervention group was treated with HHSYP plus AHP. The placebo group was treated with placebo of HHSYP and AHP. The primary end point is the histological change after 72-week treatment.Discussion: Although previous studies have confirmed the anti-fibrosis efficacy of HHSYP and AHP in CHB patients, the efficacy and safety of their combination treatment for early liver fibrosis is still not clear.Therefore, this will be the first multicenter randomized trial to prove the efficacy and safety of combination TCM treatment of HHSYP and AHP for early liver fibrosis, which will use histological changes as the primary end point. This will provide reliable data for the TCM combination treatment of early liver fibrosis and might give a new direction for further international studies on liver fibrosis.Ethics and dissemination: This study protocol was approved by the Ethics Committee of Guangdong Provincial Hospital of Chinese Medicine (BF2018-175-01) and all other participating centers (Project number2018ZX10725506-003).The study findings will be published in peer-reviewed journals and presented at the national and international conferences.
