INTRODUCTION.
 First case reported Wuhan, Hubei Province China 31, Dec. 2019.
 More than 20 million cases of COVID globally.
 600,000 global mortality.
 Every continent, except Antarctica, had reported cases.
 HTN, DM, Elderly, CHD, Lung disease patients are more susceptible and with
more comorbidities.

WHAT ABOUT COMMUNITY ACQUIRED
PNEUMONIA?
IS THERE ANY LINK WITH HTN?

HTN AND PNEUMONIA.
 > 65 years of age is risk factor for Community acquired Pneumonia.
 HTN increase with old age.
 In elderly patients with Pneumonia, HTN was one of the most common
comorbid factors.

ASSOCIATION OF ACE INH & ARB WITH COMMUNITY AQUIRED
PNEUMONIA.
 ACE inh and ARB had been shown to reduce the risk of community acquired pneumonia.
 ACE inh. and ARB were associated with lower incidence of community acquired pneumonia as
compared with CCB.
 ACE inh. and ARB are linked to lower CV mortality in patients with Community acquired
pneumonia.

ACE 2
 Membrane bound MonocarboxyPeptidase,
 Present in Lung, heart, kidney and GI.
 Convert Angiotensin II to Angiotensin 1-7.
 SARS COV2 binds to ACE2 receptors at the Alveolar epith. Cells. Reducing the ACE2 levels.
 transform Angiotensin II to Angiotensin 1-7.
 Reducing ACE 2 leads to increase Angiotensin II with its deleterious vasoconstriction, Na+
retention, Inflammation and increase fibrosis.

ACE2
 Down regulation of ACE2 is associated with sever lung injury in experimental animals.
 Angio II- AT1 receptor axis activation has been associated with the severity of lung injury.
 ACE 2 reduction is associated with Bradykinin receptor B1 causing more sever lung injury.

INFLAMMATORY CASCADE IN COVID AND THE LINK WITH
HTN

INFLAMMATION AND COVID-19 AND HTN
 Deterioration of COVID-19 is associated with proinflammatory
cytokines. IL2, IL6, IL7, TNF, Chemokines.
 Cytokines is linked with inflammatory Cytokines as IL6.
 CD4 and CD 8 are deregulated in HTN.
 Immune mechanism is associated with target organ damage in
HTN.

RESEARCH QUESTIONS?
1. Whether ACE inh/ARB would increase the possibility of infected with
COVID-19?
2. If ACE lnh/ARB would cause more sever disease in patients taking them?
3. Adding ACE inh/ARB to a COVID patient would change the disease
course?

DOES ACE INH OR ARB CAUSE MORE SEVER INFECTION?
Total 13 retrospective observational studies.
 8 in china.
 2 in Italy.
 1 UK.
 2 in USA.
Total patients 23 565.
Conclusion: use of ACE inh or ARB was not associated with increased severity of COVID

DOES ACE INH OR ARB CAUSE MORE SEVER INFECTION?
 An ongoing Prospective trial from Ireland.
 Enrolling COVID patients receiving ACE or ARM.
 Randomize to continue ACE/ARB or change to other AntiHTN medications.

ACE INH./ARB
 Insufficient evidence to conclude on the deleterious or beneficious effect of ACE
inh.
 Over expression of ACE receptors could be deleterious.
 Less controlled BP, heart failure, CKD. Withholding ACE inh. could be more
harmful.
 Alteration of immunity could be beneficious.
 Studies from China, Italy and USA did not confirm any association.

CONCLUSIONS
 Hypertension is a common comorbidity factor in COVID infection.
 It had been highly prevalent among severe cases as well as fatal COVID inf.
 The link is the ACE2 receptors.
 Alteration of ACE2 representation could affect COVID disease.
 RAAS inh. is not linked with the infection susceptibility in moderate and sever
cases.
 It does not affect the disease outcome.
