Covid has a particular affinity for blood vessels and that’s why after reaching lungs, it begins invading into the small blood vessels current within the partitions of alveoli (tiny air sacs in lungs that take up the oxygen one breathes in) and from there, it spreads to the whole physique, says a assessment paper by a bunch of researchers on the PGI.
The lead authors of the paper are Dr Suruchi Garg, a city-based dermatologist, and Dr Mandeep Garg of the PGI. Dr Nidhi, Dr Pankaj Malhotra and Dr Ritesh Agarwal of the PGI are the co-authors.
The researchers reviewed the mechanism of how Covid impacts not simply lungs, but in addition different a number of organ system of the human physique.
In response to the paper, immune modulators comparable to vitamin C, D and zinc assist a Covid affected person within the first week of sickness and blood thinners are required to be given from the second week whereas the physique is attempting to struggle the virus via varied mechanisms.
The analysis paper stated, “If the immunity of the individual is low, the virus begins multiplying, extra so in individuals with underlying co-morbidities. It invades into the capillaries of lung alveoli and creates a number of accidents resulting in microthrombi (blood clots) formation. And
then these virus-laden microthrombi get dislodged and begin circulating within the blood and have an effect on varied different organs.”
He stated, “When this occurs, the physique’s second line of defence comes into play in opposition to the viral antigens by secreting antibodies, which attempt to eradicate the virus by the formation of antigen-antibody complicated. This leads to the extreme launch of cytokines by varied immune cells of the physique and produce cytokine storm.”
Dr Mandeep Garg from the Division of Radiodiagnosis and Imaging, PGI, explains, “As soon as blood vessels of important organs comparable to coronary heart, lungs, mind and liver get occluded attributable to these two mechanisms, finish organ injury begins occurring in varied methods resulting in excessive fatality.” In response to the assessment paper, the remedy for Covid-19 must be aimed on the idea of illness pathogenesis.
