Scientific Article: “The cost-effectiveness of a novel soluble beta-glucan gel”

Keith F Cutting, 2017

Wounds that have stalled healing are costly in terms of patient morbidity and increase in use of material and financial resources. A natural polymer beta-glucans has been incorporated into a methylcellulose gel to provide a topical gel designed to accelerate healing in wounds where it has stalled. Although the gel provides an environment conducive to moist wound healing the active agent, betaglucans activate the innate immune response. Over an annual budget cycle, SBG gel is expected to heal 94% of wounds compared with 78% when given standard care. It also healed wounds more quickly, with the average expected healed weeks 34.4 in the SBG gel group, compared with 24.7 methylcellulose dressing group.”

2.) Ron Legerstee: “The central role of macrophages in wound healing and their activation by Bioactive Beta-Glucan to restart healing”
3.) Brenda King: “Bioactive Beta-Glucan in clinical practice: case reviews and proposed treatment plans”

Webinar about stalled wound healing and bioactive beta-glucan

Presented by Journal of Wound Care (JWC) and Woulgan, 2017

Module 1: “Understand why wounds stall and what happens at a molecular level”

Module 2: “Discover how macrophages in stalled wounds can be activated by stimulation with Bioactive BetaGlucan, restarting the healing process”

Narrated by Brenda King, nurse consultant in tissue viability from the UK, this short 2-module, CPD-accredited webinar will give you a unique insight into how beta-glucan can re-start stalled wound healing.

Scientific Article: “A clinical evaluation of Woulgan® Biogel in the management of non-infected diabetic foot ulcerations”

Donna Welch, 2017

Despite optimum treatment, some diabetic foot ulcers remain hard to heal. Diabetic foot ulcer progression may be delayed due to altered neutrophil function and dysfunctional macrophages with respect to the production of cytokines and growth factors essential for wound healing. Woulgan Biogel® is a sterile gel consisting of water, glycerol, carboxymethylcellulose and soluble beta-glucan (SBG). SBG stimulates Macrophages and can accelerate healing. Two case studies were completed to evaluate the effectiveness of Woulgan Biogel in managing non-infected chronic diabetic foot ulcers. Both case studies demonstrated positive patient outcomes with the ulcers healing completely. Woulgan Biogel was found to be an effective dressing and appeared to promote healing of previously static diabetic foot ulcers.

Scientific Article: “Clinical evaluation of a bioactive beta-glucan gel in the treatment of ‘hard-to-heal’ wounds”

King et al, 2017

The aim of this evaluation is to assess the effects of a wound healing gel in wounds of different aetiologies. Data was recorded on the wound surface area, tissue type, and patient level of wound pain at baseline (0) and at weeks 1, 2, 3, 4, and 8. Of the total 39 patients enrolled in the study, 26 patients who complied with the protocol criteria completed the minimum four-week study period. During the 12-week evaluation period, seven of the 26 wounds fully healed and an additional eight wounds showed a reduction in size of more than 50 %. Of the remaining 11, five wounds showed moderate healing progression and six wounds did not respond to treatment. Following the 12 week evaluation time point clinicians reported that a further three wounds healed—a 38 % healing rate

Scientific Article: “Macrophage stimulating agent soluble yeast β‐1,3/1,6‐glucan as a topical treatment of diabetic foot and leg ulcers: A randomized, double blind, placebo‐controlled phase II study”

Zykova et al, 2014

“β‐Glucans are potent inducers of immune function. The present randomized, double blind, two‐center, placebo‐controlled study was undertaken to explore safety, tolerability and efficacy of soluble β‐1,3/1,6‐glucan (SBG) as a local treatment of diabetic foot ulcers. A total of 60 patients with type 1 or 2 diabetes and lower extremity ulcers (Wagner grade 1–2, Ankle/Brachial Index ≥0.7) received SBG or a comparator product (methylcellulose) locally three times weekly up to 12 weeks in addition to conventional management scheme. A total of 54 patients completed the study.”

Scientific Paper: “Can the activation of the body’s own key cells in wound healing, WOUND MACROPHAGES, make a positive contribution in the treatment of chronic wounds?”

Skjæveland & Engstad, 2013

“A moist wound healing environment has for long been recognized as the principle for optimal healing in the treatment of wounds. Hence there are many products in the market that cater to this principle, both in terms of pure hydrogels and dressings containing moisturizing agents. Despite a huge range of products to choose from in the field of wound treatment, there is still a need for new and better products to treat complex, chronic wounds that do not heal or heal very slowly. This has resulted in the research and development of active products that not only safeguard the principles of moist wound healing, but which can also directly expedite the actual wound healing process.”

Scientific Paper: “Inflammation in chronic wounds – better than its reputation?”

Skjæveland & Grønvoll, 2017

When wound healing stalls it’s usually in the inflammatory phase, either because of a prolonged inflammation or an insufficient inflammatory response. This has lead to the general misconception that the inflammation phase is unnecessary and problematic in wound healing, especially for chronic wound conditions. This paper explains how the inflammation and proliferation phases are regulated at molecular level by macrophages and how you now can manipulate macrophage function clincally with beta-glucan stimulation. The paper is in Norwegian and was published in the december 2016 edition of “SÅR”.

Oral Presentation at NIFS – Annual Meeting of the Norwegian Wound Care Society, Fornebu 2015

“The activation of macrophages leads to positive results in the treatment of chronic wounds in a Norwegian study”

Skjæveland & Gerdts, 2015

The results of 55 patients with stalled wounds were presented, of which a majority had wounds older than several months, up until over a year old, and most of them were either diabetic foot, pressure or leg ulcers. 89% of the health care professionals involved in the evaluation stated that they wanted to continue the use of Woulgan Bioactive Beta-Glucan Gel.
