The added value of pirfenidone to declare war on inflammation and the
fibrotic state induced by Sars Cov 2
Abstract
Reduction of pulmonary fibrotic status and reduction of
hyperinflammation is essential to combat SARS-CoV-2 and avoid death.
Many authors have divided the SARS-CoV-2 infection into three stages,
the second and third of which are purely inflammatory and fibrotic.
Waiting for the development of antiviral drugs and vaccines to give good
results, the best pharmacological goal is the reduction of
proinflammatory molecules. This leads to less formation of fibrotic
tissue and to the resolution of the patient’s respiratory problems. In
fact, in phase 3, the most serious, there is a state of overexpression
of the immune system with consequent assault on all tissues and damage
to the lungs. Sars cov 2 pneumonia is characterized by “cytokine
storm” and can lead to death. Acting early and with pirfenidone
combination therapy can be effective. The IL-6 or IL-1 inhibitors,
chloroquine / hydroxychloroquine and colchicine, which are demonstrating
their anti-inflammatory efficacy, when combined with an
anti-inflammatory and antifibrotic agent, such as pirfenidone, can have
a winning result. The effective combined terepia allows to use
non-lethal dosages and affects all the pathological steps induced by the
virus. Pirfenidone has been used for years in lung diseases and has been
shown to have good clinical success and good safety and tolerability.The
purpose of this study is to explain the pharmacological logic behind the
use of a combination therapy as an effective and safe remedy to reduce
pneumonia and the consequent death from Sars CoV 2. Keywords:
