Irradiation with UV-B rays can help – healing practice

COVID-19: UV rays for the immune system

Various scientific studies have provided evidence that UV radiation fighting through that Coronavirus SARS-CoV-2 triggered disease COVID-19 could help. A new study now shows that UV-B rays in the treatment of corona sufferers can be helpful.

The number of people infected with corona is increasing and increasing. And there are still severe cases of COVID-19 whose optimal treatment is still a matter of research. An Austrian study investigates how exposure to UV-B rays affects the health of patients. The in the journal “Experimental DermatologyThe published results of the pilot study give cause for optimism.

Balance the immune system

Die Treatment of severe COVID-19 cases in the hospital is still a major challenge more than two years after the start of the pandemic. Doctors worldwide are looking for effective, simple and practical solutions to increase the chances of seriously ill patients as best as possible.

“An option that has already proven itself in other diseases with excessive immune reactions is the so-called narrowband UV-B therapy (NB-UV-B, narrowband UV-B)”, explains Univ.-Prof. Dr.med.univ. Peter Wolf from the University Clinic for Dermatology and Venereology at the Medical University (Med Uni) Graz in one Message.

deaths in connection with COVID-19 disease often correlate with a derailment of the immune system.

“That disturbed immune system can be brought back into balance with narrow-band UV-B therapy. The treatment has already shown success in other diseases such as graft-versus-host disease (GVHD) or skin cell lymphoma”explains the doctor.

“In addition, this form of therapy is still state of the art in the treatment of psoriasis (psoriasis) – especially in exanthematous forms.”, according to Wolf. The study, which has completed its pilot phase, shows that UV-B therapy in the recovery of patients suffering from COVID-19 can help.

Treatment with narrow band UV-B

For the study, 30 patients were severe forms randomly assigned to one of two groups by COVID-19. One group was treated with narrow-band UV-B, the other received placebo light irradiation.

According to the information found treatment in addition to the usual medical care, including anti-viral medication.

The therapy was carried out with a mobile UV-B device and a irradiation of around 27 percent of the body surface in the patient’s bed over a total of eight days. A first cut-off point for analysis was set 28 days after treatment. After this time, it was checked how the disease was progressing in the study patients.

Probably not directly related to vitamin D

In the group treated with narrow-band UV-B, passed away two people (13.3 percent), in the placebo group there were five (33.3 percent).

The exact mechanism of action of UV-B therapy in COVID-19 is still being investigated on an immunological level, but does not appear to be directly involved Vitamin D related, as Peter Wolf believes based on the laboratory results evaluated so far.

According to the scientist, the results of the study fit perfectly with the fact that, according to a meta-analysis, low UV values ​​in the environment and season are directly associated with increased morbidity and mortality of patients with COVID-19 correlate.

The advantage of UV-B treatment is next to its effectiveness also in its safety, the comparatively low costs, the ease of use and the possibility of carrying out this therapy in less well-equipped hospitals or poorer regions.

The results of this first study phase now serve as the basis for a planned, larger study, which aims to provide more accurate and definitive data. (ad)
