The Use of Ozone in High Frequency Device to Treat Hand Ulcers in Leprosy: a Case Study

Healing refractory livedoid vasculopathy-related skin ulcers by ozone therapy: a case-based review

Chronic skin wounds represent a prominent etiological factor in the occurrence of non-traumatic foot amputations on a global scale and pose a substantial threat to the patient's well-being and mortality in the absence of effective treatment strategies. There exists a subset of patients that exhibit an insufficient response to different treatment options, comprising antibiotics, dressings, gauze bandages, debridement, rehabilitation, collagen patch, and vacuum-assisted closure. In this patient group, distinct treatment strategies emerge before surgery and amputation. Ozone therapy is one of them. Ozone exhibits a wide variety of effects such as antimicrobial, anti-inflammatory, antioxidant, and trophic. Its trophic effect is mediated by disinfection, stimulation of granulation tissue, acceleration of the angiogenesis process, and detoxification mechanisms. In this article, we presented the beneficial effect of ozone therapy in a case of chronic skin ulcer associated with livedoid vasculopathy. In this context, we aimed to discuss the role of ozone therapy in the management of chronic skin ulcers. Finally, we focused on ozone therapy as a promising method in inflammatory rheumatic diseases.

Effectiveness of Ozone Therapy as an Adjunct Treatment for Lower-Limb Ulcers: A Systematic Review

OBJECTIVE

To evaluate the effectiveness of topical ozone therapy as an adjuvant treatment in the healing of lower limb ulcers through a systematic literature review.

DATA SOURCES

Three databases were used to search for studies conducted in the period up to and including September 2020: PubMed, Scopus, and the Web of Science.

STUDY SELECTION

The search identified 44 studies, 7 of which met the eligibility criteria and were evaluated.

DATA EXTRACTION

Study design, study location, number of patients, patient age, type of control, wound type, intervention type, equipment used to generate ozone (ozone generation), evaluation methodology, and main results were extracted from each study.

DATA SYNTHESIS

A total of 506 patients 18 years or older with chronic wounds, such as venous or diabetic ulcers, on the lower limbs were enrolled. The majority of studies addressed diabetic foot ulcers.

CONCLUSIONS

The ozone therapy protocols demonstrated a healing effect in all included studies, and none reported adverse effects. This reinforces the need for more controlled and randomized clinical trials to determine the effectiveness of this treatment and establish clinical criteria for its use.

Topical ozonated virgin coconut oil improves wound healing and increases HSP90α, VEGF-A, EGF, bFGF and CD34 in diabetic ulcer mouse model of wound healing

Background: Diabetes is a disease that affects people worldwide, including in Indonesia. The prevalence of diabetes in Indonesia is increasing from year to year. One of the most devastating complications of diabetes mellitus is diabetic ulcers, which is a limb-threatening complication. Over the past few decades, ozone generated using plasma medical technology has been investigated as an agent that helps wound healing. This study aims to evaluate the effects of topical ozonated virgin coconut oil (VCO) in a diabetic wound mouse model. Methods: This study was an experimental study with a post-test control design. An ulcer wound model was made in 50 diabetic male Wistar mice, divided into five groups, and a control group of 10 non-diabetic mice. The control groups were given conventional therapy only and the treatment groups were also given topical ozonated VCO with different flow durations (0 min, 90 min, 7 h, 14 h). Macroscopic appearance and wound contraction were observed. HSP90β, VEGF-A, EGF, bFGF and CD34 levels were measured from the immunostained slices of wound margins. Results: The reduction of wound length was proportionally related to the duration of ozone flow. Ozonated VCO with a longer duration of ozone flow healed the wound more quickly and had the shortest wound length. VCO with ozone flow for 14 hours (16837.10 µm) had the biggest reduction in wound length compared to other groups. The wounds treated with ozonated VCO showed an increase in HSP90β, VEGF-A, EGF, bFGF and CD34 levels that correlated to improved wound healing. A longer period of treatment resulted in higher levels of wound healing biomarkers compared to shorter therapeutic durations. Conclusions: Topical ozonated VCO improved the wound healing process in a diabetic ulcer mouse model by improving macroscopic wound appearance and increasing levels of wound healing biomarkers.
