BANGKOK: A hospital here has successfully used plasma from a recovered Covid-19 patient to treat those with critical symptoms of the disease.
Dr Sarunyou Chusri, an infectious disease specialist at the Internal Medicine Department, Faculty of Medicine, Prince of Songkla University, said the cured patient returned home on May 19.
The patient was sent from Narathiwat province to be treated initially with the standard anti-retroviral drug Favipiravir at the Songklanagarind Hospital for three days, with no improvement.
According to reports in the Bangkok Post, the patient displayed symptoms, including decreased blood oxygen, low heart rate and respiratory failure.
Endotracheal intubation was performed, along with complementary treatment of using plasma donated by the first Covid-19 patient who recovered through standard hospital treatment.
The medical team injected 200cc of plasma twice, and after three to four days, the patient's respiratory function and heart rate improved, while inflammation decreased.
The viral load in the patient's pharynx was also below measurable levels. Pneumonia symptoms in the patient have eased, and the patient could be taken off a ventilator, said Dr Sarunyou.
"However, we still can't say this treatment will work for everyone; it has to be considered on a case-by-case basis. The recovery of this patient is considered a successful individual treatment case."
The use of plasma is not viewed as a preventative procedure. Rather, it is considered to be a complementary treatment performed only when a patient does not recover through standard means.
Nevertheless, recovered patients have contacted Songklanagarind Hospital to donate their plasma to the hospital's blood bank, the doctor said.
Donors must be tested to ensure they are free from any infectious disease. Normally, 400-600cc of blood can be donated at a time, and donations can be repeated if immunity is sufficient.
