At-home laser treatment of oral neuronal disorders: Case reports

Treatment of diabetic foot ulcers in a frail population with severe co-morbidities using at-home photobiomodulation laser therapy: a double-blind, randomized, sham-controlled pilot clinical study

PURPOSE

To evaluate the safety and efficacy of an at-home photobiomodulation (PBM) device for the treatment of diabetic foot ulcers (DFUs) in a frail population with severe comorbidities.

METHODS

Prospective, randomized, double-blind, sham-controlled pilot study. Patients (age = 63 ± 11 years, male:female 13:7) with insulin-dependent diabetes type 2, neuropathy, peripheral artery disease, significant co-morbidities, and large osteomyelitis-associated DFUs (University of Texas grade ≥ III) were randomized to receive active (n = 10) or sham (n = 10) at-home daily PBM treatments (pulsed near-infrared 808 nm Ga-Al-As laser, 250 mW, 8.8 J/cm²) for up to 12 weeks in addition to standard care. The primary outcome was the %wound size reduction. The secondary was adverse events.

RESULTS

With the numbers available, PBM-treated group had significantly greater %reduction compared to sham (area [cm²], baseline vs endpoint: PBM 10[20.3] cm² vs 0.2[2.4] cm²; sham, 7.9 [12.0] cm² vs 4.6 [13.8] cm², p = 0.018 by Mann-Whitney U test). Wound closure > 90% occurred in 7 of 10 PBM-treated patients but in only 1 of 10 sham patients (p = 0.006). No adverse device effects were observed.

CONCLUSIONS

Photobiomodulation at home, in addition to standard care, may be effective for the treatment of severe DFUs in frail patients with co-morbidities and is particularly relevant at these times of social distancing. Our preliminary results justify the conduction of a larger clinical trial. ClinicalTrials.gov: NCT01493895.

Auto-Administered Photobiomodulation on Diabetic Leg Ulcers Treatment: A New Way to Manage It?

Background

Peripheral arterial disease is a dramatic consequence of an uncontrolled diabetic condition causing an increase of morbidity and mortality and its treatment is currently medical or surgical, finally requiring, in the 7–20% of cases, major or minor amputation. Photobiomodulation therapy (PBM) is a laser treatment used in medicine, thanks to its ability to stimulate the wound healing, the acceleration of inflammatory process, and the modulation of pain. Recently, the self-administration of the treatment has been suggested for different purposes in medicine and dentistry with a great number of advantages and no side effects.

Methods

A 84-year-old woman affected by diabetes type 2 and positive for diabetes complications had diagnosis for an ulcerative lesion of 1 cm diameter on her right leg and started a treatment of the lesion applying the B-Cure Laser Pro (Erika Carmel, Haifa, Israel) on her own with a fluence per minute of 3.2 J/cm² for 2 sessions of 15 minutes by cutaneous application.

Results

After a week of treatment, the ulcer dried and crusted, finally providing complete healing after 30 days of treatment.

Conclusion

With this short case report, we think to add a further contribution by suggesting this kind of treatment for successful management of the leg ulcers in diabetic patients.
