*Patients with HIV with co-existing underlying comorbidities like diabetes mellitus, hypertension, etc may have increased expression of ACE-2 receptors in the tissues causing increased binding of SARS-CoV-2 virus and replication leading to high viral load.
*Exact mechanism of interaction of SARS-CoV-2 virus and HIV virus is unclear but it is suspected that since both of the virus cause immune deficiency, they might be causing more severe immuological consequence.
*It is also suspected that defective cellular immunity in people living with HIV might be protective for severe cytokine dysregulation, observed in patients with COVID-19
*High viral load of SARS-CoV-2 virus could lead to manifestations of pneumonia, cardiac dysfunction, multi-organ dysfunction

==Diagnosis==
===Diagnostic Study of Choice===


=== '''Diagnostic Criteria''' ===
*The diagnosis of [[COVID-19]] in HIV patients remains the same as compared to the general population.<ref name=":2" /><ref name=":0" />
* The challenge of diagnosing [[COVID-19]] in HIV patients is to clinically distinguish it from common mimickers such as Influenza, Parainfluenza, and [https://www.wikidoc.org/index.php/COVID-19_and_influenza_co-infection other common respiratory illnesses]. Currently, history of exposure and epidemiological risk factors are the two biggest historical cues, aside from respiratory symptoms, that can guide clinician into considering [[COVID-19]] in the differential diagnosis.
=== Diagnostic Study of Choice ===
* [[RRT-PCR|RT-PCR]] is the standard diagnostic of choice to confirm cases and for active [[COVID-19]] cases. It may take up to 8 weeks for [[Reverse transcription polymerase chain reaction|RT-PCR]] to become negative, and so a repeat RT-PCR is no longer required to document recovery.<ref>{{Cite web|url=https://www.acpjournals.org/doi/10.7326/M20-1495|title=Variation in False-Negative Rate of Reverse Transcriptase Polymerase Chain Reaction–Based SARS-CoV-2 Tests by Time Since Exposure|last=Kucirka et al.|first=Lauren|date=May 13, 2020|website=acp journals|archive-url=|archive-date=|dead-url=|access-date=July 11, 2020}}</ref>

===Medical Therapy===
===Medical Therapy===


* Treatment of COVID-19 patients with HIV is similar to current guidelines of treatment of general population with [[COVID-19]] along with current maintenance of their antiretroviral therapy. No specific antretroviral therapy has been found effective against SARS-CoV-2 virus. Following treatment have been used in HIV individuals with COVID-19 infection.


* Supportive care-Patients with HIV who develop mild [[COVID-19]] illness could be treated with supportive care with symptomatic relief at home. They should continue their antiretroviral therapy. <ref name=":0" />

Overview

  • An observational prospective study found out that the incidence of HIV-infected individuals to be affected by SARS-CoV-2 was similar to the general population.
  • Specific antiretroviral therapy did not affect COVID-19 severity.
  • Immunosuppression(low CD4 cell counts) was associated with COVID-19 severity.
  • Patients with HIV infection often have other comorbidities(lung disease, cardiovascular disease) therefore, increasing the risk for severe-COVID-19 disease.
  • Patients with HIV infection with CD4 cell count<200/mm3 are at increased risk for complications from other respiratory infections. However, we do not know if this is the scenario with COVID-19

Historical Perspective

  • COVID-19 caused by SARS-CoV-2 was first identified in late December 2019 in Wuhan, Hubei China.
  • Due to its rapid spread worldwide from person to person it was declared as a pandemic by WHO on March 11, 2020. another most dangerous virus causing acquired immunodeficiency syndrome (AIDS). According to WHO, there are ~37.9 million people living with HIV.[1]
  • On March10, 2020 CDC mentioned that people with HIV would be at increased risk for severe COVID-19 infection.[2]
  • On March 11, 2020, the first case study was published on a person living with HIV who developed and recovered from COVID-19.[3]
  • On March 20, US Department of Health and Human services posted interim COVID-19 guidance for HI positive individuals.[4]
  • On April 15, the first case series was published in people living with HIV who developed COVID-19.[5]
  • On May 28 a prospective study was published in Lancet describing the epidemiology and clinical characteristics of the COVID-19 in HIV individuals.[6]

Pathophysiology

  • COVID-19 is caused by the SARS-CoV-2 virus which enters into the cells by attacking its primary receptor, Angiotensin-converting enzyme 2. ACE-2 receptors are expressed in pulmonary tissues and extrapulmonary system tissues(heart, kidney, endothelium, and intestine).[7]
  • Patients with HIV with co-existing underlying comorbidities like diabetes mellitus, hypertension, etc may have increased expression of ACE-2 receptors in the tissues causing increased binding of SARS-CoV-2 virus and replication leading to high viral load.
  • Exact mechanism of interaction of SARS-CoV-2 virus and HIV virus is unclear but it is suspected that since both of the virus cause immune deficiency, they might be causing more severe immuological consequence.
  • It is also suspected that defective cellular immunity in people living with HIV might be protective for severe cytokine dysregulation, observed in patients with COVID-19
  • High viral load of SARS-CoV-2 virus could lead to manifestations of pneumonia, cardiac dysfunction, multi-organ dysfunction

Causes

COVID-19 infection in HIV infected individuals is caused by SARS-CoV-2 virus

Differentiating from other disease

COVID-19 infection in HIV individuals should be differentiated from other opportunistic infections and other respiratory infections such as Influenza, Parainfluenza, and other common respiratory illnesses

Epidemiology and Demographics

  • Different studies have not shown any difference in the incidence rate of COVID-19 in HIV individuals as compared to the general population.
  • A prospective observational study of 2873 HIV individuals showed an incidence of the rate of COVID-19 in HIV individuals of 17.7 cases per 1000 population.[4]

Age

  • The median age found out in a study was 53.3 years. [4]

Gender

  • Study found that the majority of people living with HIV who developed COVID-19 were male.[4]

Race

There is insufficient information regarding race-specific prevalence or incidence HIV SARS-CoV-2 coinfection.

Comorbitdities

There is increased prevalence of comorbidities in HIV–SARS-CoV-2 co-infected individuals. They are associated with following comorbidities.[6]

Risk Factors

At present people with HIV who are at greatest risk of Severe COVID-19 infection are people[4] -

  • who have low CD4 cell count.
  • not on antiretroviral therapy.
Specific Populations with HIV at risk for COVID-19

Pregnancy

  • Pregnant individuals with HIV are at greater risk for severe illness, morbidity, or mortality as compared with the general population due to coronavirus infections(SARS-CoV and MERS-CoV) and other viral respiratory infections like influenza. [8]Data related to COVID-19 is limited but pregnant individuals with HIV are suspected to be at greater risk due to SARS-COV-2 similarity with other coronaviruses (SARS-CoV and MERS).[9][10]
  • They are suspected to be at increased risk of preterm delivery, adverse neonatal outcomes.[9] In a small series of pregnant women with COVID-19 adverse outcomes such as fetal distress and preterm delivery have been noted. They have also been reported with SARS-CoV and MERS.[11][12][13]
  • Vertical Transmission of COVID-19 has not been found.[14][15][16][17]

Older Adults

  • Older adults(>50 years age) with HIV have a greater risk of having co-existing comorbidity including diabetes, hypertension, cardiovascular disease, and chronic lung disease as compared with general population. Therefore, older adults with HIV are suspected to be at an increased risk of COVID-19 infection.[18]
  • It is recommended that they follow the recommendations outlined for patients with HIV.

Screening

There is insufficient information regarding screening of COVID-19 in people living with HIV.

Natural History, Complications and Prognosis

Natural History

  • If left untreated it might lead to pneumonia and multi-organ failure.

Complication

Diagnosis

Diagnostic Criteria

  • The diagnosis of COVID-19 in HIV patients remains the same as compared to the general population.[8][10]
  • The challenge of diagnosing COVID-19 in HIV patients is to clinically distinguish it from common mimickers such as Influenza, Parainfluenza, and other common respiratory illnesses. Currently, history of exposure and epidemiological risk factors are the two biggest historical cues, aside from respiratory symptoms, that can guide clinician into considering COVID-19 in the differential diagnosis.

Diagnostic Study of Choice

  • RT-PCR is the standard diagnostic of choice to confirm cases and for active COVID-19 cases. It may take up to 8 weeks for RT-PCR to become negative, and so a repeat RT-PCR is no longer required to document recovery.[19]
  • Antibody tests are helpful in detecting previous COVID-19 infection and are likely to be most useful if used within 15 days or more after the onset of symptoms[20]

History and Symptoms

Laboratory Findings

HIV individuals with coinfection with COVID-19 are associated with following laboratory findings[4]

Inflammatory markers

Elevation of inflammatory markers like ESR, C reactive protein, procalcitonin, IL-6, IL-12, d-dimer, ferritin is seen in HIV patients co-infected with HIV[4]

X-ray

Xray of patients with HIV co-infected with COVID-19 may show[4]

  • Consolidation
  • Interstitial pulmonary infiltrates
  • Bilateral pulmonary infiltrates

Treatment

Medical Therapy

  • Treatment of COVID-19 patients with HIV is similar to current guidelines of treatment of general population with COVID-19 along with current maintenance of their antiretroviral therapy. No specific antretroviral therapy has been found effective against SARS-CoV-2 virus. Following treatment have been used in HIV individuals with COVID-19 infection.
  • Supportive care-Patients with HIV who develop mild COVID-19 illness could be treated with supportive care with symptomatic relief at home. They should continue their antiretroviral therapy. [10]
  • In case of moderate to severe COVID-19 infection they might need to be hospitalized. ART therapy should be continued when hospitalized.
  • Llopinavir–ritonavir- It inhibits the activity of the HIV-1 protease. Clinical trial found that treatment with lopinavir–ritonavir was not associated with clinical improvement in COVID-19 patients.[4][10][21]
  • Tocilizumab -which is a monoclonal antibody which binds to interleukin-6,. It has been used in patients with HIV who develop COVID-19. A retrospective study found it effective in reducing nortalility in severe COVID-19 patients [4]
  • Darunavir- It has been used in HIV SARS-CoV-2 coinfected individuals as part of their continued anti retroviral therapy. Trial has found no benefit in COVID-19 patients.[4]
  • Antibiotics such as azithromycin have been used inHIV SARS-CoV-2 coinfected individuals. [4]
  • Patients who are taking investigational ARV medication as part of their regimen, should be continued on the same medication if possible.[10]
  • Patients who have underlying medical conditions should be managed accordingly to prevent complications of COVID-19 infection.
