A Review on the Effect of COVID-19 in Pregnant Women

Coronavirus Disease 2019 (COVID-19) is an emerging disease with a rapid increase in cases and deaths since its first discovery in December 2019, in Wuhan, China. Limited data are available on COVID-19 effects during pregnancy;however, information on diseases associated with other highly pathogenic coronaviruses (i.e. Severe Acute Respiratory Syndrome [SARS] and the Middle East respiratory syndrome [MERS]) may provide insight into the effects of COVID-19 during pregnancy. Coronaviruses cause illnesses ranging from the common cold to severe respiratory disease and death. The data indicate an average of 5 days incubation period (range: 2-14 days). The average age range of the hospitalized patients was 49-56 years, and a third to half of them have an underlying illness. Children were rarely mentioned. Within hospitalized cases, men were more frequent (54%-73%). Fever, cough, myalgia, vomiting, and diarrhea are common symptoms. This review aims at giving an in-depth understanding of COVID-19 by comparing its effects with SARS and MERS to evaluate its severity in pregnant women1. The results of varied studies show that COVID-19 affects pregnant women seriously and there is an alarming need to look into this aspect to prevent its harmful effects on the fetus.Copyright © 2020

T-cell immune response to SARS-CoV-2 in HIV patients.

Objective. To assess the T-cell immune status against SARS-CoV-2 in HIV patients with or without antiretroviral therapy. Patients and methods. The study included 21 HIV patients who had laboratory-confirmed COVID-19 between September and December 2021 without previous immunization against SARS-CoV-2. The characteristics of HIV infection (CD4-lymphocytes count, HIV viral load in blood plasma, the presence of antiretroviral therapy) and COVID-19 (the severity degree and duration of the disease) were analyzed, the T-cell immune response to SARS-CoV-2 was assessed using the ELISPOT method 1 month after COVID-19. Statistical analysis was carried out by non-parametric methods (Mann-Whitney U test, Spearman's rank correlation coefficient) using the IBM SPSS Statistics 22 software package. Results. The study showed a more favorable course of COVID-19 in HIV-infected persons who achieved HIV suppression in the blood: a mild form of the disease was significantly more common, and the virus was eliminated faster. T-cell immune response to SARS-CoV-2 was recorded more frequently in these patients. Significant correlation of T-cell immune status with the CD4-lymphocytes count and HIV suppression in the blood was revealed. Conclusion. Thus, T-cell immune response to SARS-CoV-2 as assessed using the ELISPOT method was registered significantl.Copyright © 2023, Dynasty Publishing House. All rights reserved.

Successful ECMO course in an Acquired Immune Deficiency Syndrome (AIDS) patient with ARDS complicated by pneumocystis jirovecii pneumonia and COVID-19: A unique case

Objectives: Reviewing current literature and case reports of patients placed on Venous-Venous ECMO support for HIV and AIDS, with confection with Pneumocystis pneumonia and covid-19 pneumonia. The use of extracorporeal membrane oxygenation (ECMO) in patients who have acute respiratory distress syndrome has been shown to have very good outcomes. However, there is limited data to support the initiation of ECMO in patients who have human immunodeficiency virus infection with or without acquired immune deficiency syndrome. Method(s): We present a unique and challenging case of a 30 year old male, with no known past medical history, unvaccinated against covid-19, who presented with one week of progressive shortness of breath. On admission he was found with moderate bilateral infiltrates and was diagnosed with covid-19 pneumonia. Despite appropriate medical therapy, patient developed worsening hypoxic respiratory failure. Found to have elevated (1- 3)-7beta;-d-glucan and tested positive for HIV. CD4 count 11, HIV viral load 70,000. The patient remained severely hypoxemic despite mechanical ventilation, sedation, paralytics and proning. Venous venous extracorporeal membrane oxygenation was initiated. Considering his non improvement with variety of antivirals and antibiotics and with elevated (1-3)-7beta;-d-glucan in the setting of AIDS he was treated for presumed Pneumocystis pneumonia. The patient tolerated proning while on VV ECMO and his course was complicated with bilateral pneumothorax necessitating chest tube placement. Result(s): The patient successfully completed 64 days on VV ECMO, where he was treated for PCP pneumonia, covid pneumonia, CMV viremia and tolerated initiation of anti-retroviral therapy. Patient was successfully decannulated, and ultimately discharged from the hospital. Conclusion(s): VV-ECMO can be a beneficial intervention with successful outcomes in severely immunocomprimised patients with AIDS. This case highlights the importance of minimizing sedation and early mobilization on ECMO support. (Figure Presented).

Extracorporeal cytokine hemadsorption in severe COVID-19 respiratory failure

Background: At least 20% of coronavirus disease 2019 (COVID-19) patients develop acute hypoxemic respiratory failure requiring admission to intensive care unit in 5-32% of the cases. Hyper-inflammatory activation characterized by immune cell infiltration and elevated levels of cytokines was reported as the main mechanism leading to critical illness and severe acute respiratory distress syndrome (ARDS). CytoSorb is currently used for all the conditions where elevated levels of cytokines are present. Along with the beneficial effect on systemic inflammation, CytoSorb can be easily integrated with all extracorporeal circulation systems. Case Presentation: Here, we present the laboratory and clinical outcomes of 11 patients with microbiological confirmed SARS-CoV-2 infection. These patients were treated with CytoSorb to remove the excess of cytokine. All patients were male, overweight and only 3 (27%) were over 70 years old. Median age was 62 years and median body mass index was 28. Best supportive care was provided according to hospital guidelines of that moment and included antibiotic therapy, antiretroviral therapy and protective ventilation. Result(s): Cytokines levels were evaluated before and after treatment. A significant reduction of IL-6, IL-8, IL-10 and IL-1beta was observed. A significant drop of C-reactive protein (CRP) median levels was observed starting from 48 hours after treatment start levels. The decrease in the inflammatory status was associated with a progressive improvement in the respiratory function, with a significant increase in P/F from the first day after the end of the therapy. A similar trend was observed for procalcitonin. Conclusion(s): CytoSorb therapy proved to be safe in COVID-19 patients. A clinical improvement was observed in most of the treated patients despite the severity of the disease. In this study CytoSorb was used empirically for 24- 48 hours based on previous experience in septic shock. The persistence of significant levels of IL-6 and CRP after CytoSorb treatment may suggest that a prolonged treatment can improve the efficacy in controlling COVID-19 hyperinflammatory status.

Unexpected effects of COVID-19 outbreak: adaption of Anti-Retroviral Therapy (ART) delivery policies improved adherence in a population of People Living With HIV (PLWH).

Background: Adherence to Anti-Retroviral Therapy (ART) is crucial for People Living With HIV (PLWH). In Italy, ART is delivered by Hospital Pharmacies, on a renewable prescription from the hospital physician. The measurement of package-refill (the rate of ART packages actually collected out of those to be collected in order to comply with therapy) is an effective tool to evaluate the adherence.During COVID-19 outbreak, at "D. Cotugno" hospital in Naples, Italy, the ART delivery policies have been adapted, in order to reduce the number of patients' access. We analysed the impact of these changes on the pill-refill of ART in January-August 2020, compared with 2018-2019. Methods: "D. Cotugno" hospital is a mono-specialistic Infectious Diseases hospital, caring for about 2500 PLWH. Since February 2020, the hospital was almost entirely dedicated to COVID-19 patients. All out-patient activities were interrupted, except for those dedicated to HIV/AIDS patients.In this preliminary study we included all patients assigned to one of the three Medical Divisions dedicated to HIV, who were already under treatment since at least 2017. Rate of package-refill was obtained by the Hospital Pharmacy registry, demographic and clinical data were derived from clinical database.During COVID-19, many measures were adopted in order to increase safety of PLWH attending to hospital. Among these, medical prescription validity increased from 4 to 6 months, and number of packages to be collected increased from 2 to 4, adopting a multi-month dispensing strategy.Package-refill is adequate if at least 95% of ART have been actually collected; partial and inadequate if 75%-94% or less than 75% of ART, respectively, have been collected. Package-refill was measured during the first year of COVID-19 (March 2020 - February 2021), compared to the same period in the two years before. Results: A total of 594 PLWH were included. PLWH with optimal pill-refill significantly increased in 2020-21 compared to 2018-2020 (62% vs 55%, p 0.013). Discussion: Due to COVID-19, we would have expected a reduction in ART deliveries. Surprisingly, the opposite occurred. The increase of pill-refill rates may be due to different reasons, but we hypothesized that the adaption of delivery policies, with a higher number of packages allowed to be collected, strongly contributed to this result. This study suggests that multi-month dispensing policies may contribute to the improvement of adherence among PLWH.

Differences in adoption of COVID-19 pandemic related preventive behaviour by viral load suppression status among people living with HIV during the first wave of the pandemic.

BACKGROUND: Adherence to antiretroviral therapy and COVID-19 preventive behaviours among people living with HIV during the pandemic has received little attention in the literature. To address this gap in knowledge, the present study assessed the associations between viral load, adherence to antiretroviral therapy and the use of COVID-19 prevention strategies during the first wave of the COVID-19 pandemic. This was a secondary analysis of data generated through an online survey recruiting participants from 152 countries. Complete data from 680 respondents living with HIV were extracted for this analysis. RESULTS: The findings suggest that detectable viral load was associated with lower odds of wearing facemasks (AOR: 0.44; 95% CI:0.28-0.69; p < 0.01) and washing hands as often as recommended (AOR: 0.64; 95% CI: 0.42-0.97; p = 0.03). Also, adherence to the use of antiretroviral drugs was associated with lower odds of working remotely (AOR: 0.60; 95% CI: 0.38-0.94; p = 0.02). We found a complex relationship between HIV positive status biological parameters and adherence to COVID-19 preventive measures that may be partly explained by risk-taking behaviours. Further studies are needed to understand the reasons for the study findings.

Efficacy and Durability of Dolutegravir- or Darunavir-Based Regimens in ART-Naïve AIDS- or Late-Presenting HIV-Infected Patients.

BACKGROUND: Since limited data are available, we aimed to compare the efficacy and durability of dolutegravir and darunavir in advanced naïve patients. METHODS: Retrospective multicenter study including AIDS- or late-presenting (def. CD4 ≤ 200/µL) HIV-infected patients starting dolutegravir or ritonavir/cobicistat-boosted darunavir+2NRTIs. Patients were followed from the date of first-line therapy initiation (baseline, BL) to the discontinuation of darunavir or dolutegravir, or for a maximum of 36 months of follow-up. RESULTS: Overall 308 patients (79.2% males, median age 43 years, 40.3% AIDS-presenters, median CD4 66 cells/µL) were enrolled; 181 (58.8%) and 127 (41.2%) were treated with dolutegravir and darunavir, respectively. Incidence of treatment discontinuation (TD), virological failure (VF, defined as a single HIV-RNA > 1000 cp/mL or two consecutive HIV-RNA > 50 cp/mL after 6 months of therapy or after virological suppression had been achieved), treatment failure (the first of TD or VF), and optimal immunological recovery (defined as CD4 ≥ 500/µL + CD4 ≥ 30% + CD4/CD8 ≥ 1) were 21.9, 5.2, 25.6 and 1.4 per 100 person-years of follow-up, respectively, without significant differences between dolutegravir and darunavir (p > 0.05 for all outcomes). However, a higher estimated probability of TD for central nervous system (CNS) toxicity (at 36 months: 11.7% vs. 0%, p = 0.002) was observed for dolutegravir, whereas darunavir showed a higher probability of TD for simplification (at 36 months: 21.3% vs. 5.7%, p = 0.046). CONCLUSIONS: Dolutegravir and darunavir showed similar efficacy in AIDS- and late-presenting patients. A higher risk of TD due to CNS toxicity was observed with dolutegravir, and a higher probability of treatment simplification with darunavir.

Tenofovir-Containing Antiretroviral Therapy and Clinical Outcomes of SARS-CoV-2 Infection in People Living with HIV.

Tenofovir has been hypothesized to be effective against COVID-19 and is available as two prodrugs, tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF), both part of antiretroviral therapy (ART) regimens. People living with human immunodeficiency virus (PLWH) might be at higher risk for COVID-19 progression; however, information about the impact of tenofovir on COVID-19 clinical outcomes remains controversial. The COVIDARE is a prospective observational multicentric study in Argentina. PLWH with COVID-19 were enrolled from September 2020 to mid-June 2022. Patients were stratified according to baseline ART into those with tenofovir (TDF or TAF) and those without. Univariate and multivariate analyses were performed to evaluate the impact of tenofovir vs. non-tenofovir-containing regimens on major clinical outcomes. Of the 1155 subjects evaluated, 927 (80%) received tenofovir-based ART (79% TDF, 21% TAF) whilst the remaining population was under non-tenofovir regimens. The non-tenofovir group had older age and a higher prevalence of heart and kidney disease. Regarding the prevalence of symptomatic COVID-19, tomographic findings, hospitalization, and mortality, no differences were observed. The oxygen therapy requirement was higher in the non-tenofovir group. In the multivariate analyses, a first model with adjustment for viral load, CD4 T-cell count, and overall comorbidities showed that oxygen requirement was associated with non-tenofovir ART. In a second model with adjustment by chronic kidney disease, tenofovir exposure was not statistically significant.

Achieving the "Ending the HIV Epidemic in the U.S." incidence reduction goals among at-risk populations in the South.

INTRODUCTION: Antiretroviral medication coverage remains sub-optimal in much of the United States, particularly the Sothern region, and Non-Hispanic Black or African American persons (NHB) continue to be disproportionately impacted by the HIV epidemic. The "Ending the HIV Epidemic in the U.S." (EHE) initiative seeks to reduce HIV incidence nationally by focusing resources towards the most highly impacted localities and populations. This study evaluates the impact of hypothetical improvements in ART and PrEP coverage to estimate the levels of coverage needed to achieve EHE goals in the South. METHODS: We developed a stochastic, agent-based network model of 500,000 individuals to simulate the HIV epidemic and hypothetical improvements in ART and PrEP coverage. RESULTS: New infections declined by 78.6% at 90%/40% ART/PrEP and 94.3% at 100%/50% ART/PrEP. Declines in annual incidence rates surpassed 75% by 2025 with 90%/40% ART/PrEP and 90% by 2030 with 100%/50% ART/PrEP coverage. Increased ART coverage among NHB MSM was associated with a linear decline in incidence among all MSM. Declines in incidence among Hispanic/Latino and White/Other MSM were similar regardless of which MSM race group increased their ART coverage, while the benefit to NHB MSM was greatest when their own ART coverage increased. The incidence rate among NHB women declined by over a third when either NHB heterosexual men or NHB MSM increased their ART use respectively. Increased use of PrEP was associated with a decline in incidence for the groups using PrEP. MSM experienced the largest absolute declines in incidence with increasing PrEP coverage, followed by NHB women. CONCLUSIONS: Our analysis indicates that it is possible to reach EHE goals. The largest reductions in HIV incidence can be achieved by increasing ART coverage among MSM and all race groups benefit regardless of differences in ART initiation by race. Improving ART coverage to > 90% should be prioritized with a particular emphasis on reaching NHB MSM. Such a focus will reduce the largest number of incident cases, reduce racial HIV incidence disparities among both MSM and women, and reduce racial health disparities among persons with HIV. NHB women should also be prioritized for PrEP outreach.

Progress of the Gulf Cooperation Council (GCC) Countries Towards Achieving the 95-95-95 UNAIDS Targets: A Review.

BACKGROUND: In 2014, the Joint United Nations Programme on HIV/AIDS (UNAIDS) and partners launched the 90-90-90 targets. These were further updated to correspond to 95-95-95 by the year 2025. We present an overview of the progress made by Gulf Cooperated Council (GCC) countries towards meeting the global targets. METHODS: We extracted data from Global AIDS Monitoring (GAM), UNAIDS AIDS Info, HIV case reporting database, and the WHO global policy uptake for six countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab of Emirates (UAE) to assess the HIV/AIDS burden in the six GCC countries, and the progress towards achieving the 95-95-95 goal. RESULTS: By the end of 2021, an estimated 42,015 people living with HIV (PLHIV) were residing in the GCC countries with prevalence levels below 0.01%. Data from four GCC countries, Bahrain, Oman, Qatar and UAE, indicated that by 2021, 94%, 80%, 66%, and 85% of HIV-positive population knew their status, respectively. 68%, 93% (2020 data), 65%, 58% and 85% of PLHIV in Bahrain, Kuwait, Oman, Qatar and UAE who knew their status were on anti-retroviral therapy (ART), respectively, and 55%, 92%, 58% and 90% (2020 data) among those who were on ART had viral suppression in Bahrain, Kuwait, Oman and KSA, respectively. CONCLUSION: The GCC countries have made great strides toward fulfilling the 95-95-95 targets, but the interim 2025 overall UNAIDS targets remain unmet. The GCC countries must strive diligently to accomplish the targets by emphasising early identification of the cases by enhanced screening and testing, as well as prompt commencement of ART therapy with viral load suppression.

Tuberculosis and Hiv Infection - So Many Questions Pending

Since the early days of HIV infection, back in the eighties, TB - particularly extrapulmonary TB emerged as one of the opportunistic infections affecting these patients, specifically as a reactivation of latent TB infections. A diagnosis of TB in the context of HIV infection was then considered as an 'AIDS defining condition' according to classification systems used at that time. It has been recognized for a long time that there are many interactions between HIV and Mycobacterium tuberculosis, which lead to further immune deterioration and to worsening of both conditions due to complex biological and mechanistic interactions between these two agents. Many methods and techniques have been proposed in order to improve diagnosis of TB in HIV-infected subjects, knowing that TB is the most frequent opportunistic infection;and, if not treated in a timely fashion, it may easily take the lives of affected patients. It is not easy to have a diagnosis of TB in HIV-infected subjects, because of the difficulties for obtaining adequate sputum samples, or because of lack of adequate facilities for making a timely diagnosis, particularly in the so-called developing world. On the other hand, extrapulmonary TB is most frequently found in HIV-infected individuals compared to non-infected subjects, and its diagnosis poses significant difficulties, since so many times invasive procedures must be performed in order to obtain an adequate tissue sample and then be able to identify the pathological characteristics of tuberculous disease. In the first days of HIV infection when no antiretroviral therapy was available, a diagnosis of TB was made on clinical grounds, considering a history of contact or some characteristics of the disease, and those of us who are old (or experienced) enough offered antituberculosis therapy for these subjects, obtaining an adequate response many times, but in all cases, the natural history of HIV infection took place, and ultimately these patients died because of the occurrence of another opportunistic infection (or malignancy). With the advent of antiretroviral therapy in the late nineties, another problem occurred. The possibility of drug-drug interactions, taking into account hepatic metabolism of rifampin and the alterations of antiretroviral drug blood - or tissue - concentrations. On top of this, the occurrence of IRIS became another problem, and strategies and protocols have been designed in order to establish the adequate timing of antituberculosis therapy and sometime later antiretroviral therapy. A last point to be considered is the COVID-19 pandemic. The question to be asked is what the influence of the pandemic has been for affecting TB and HIV diagnosis and therapy strategies and programs, particularly in the developing world, knowing that health systems in these countries have many limitations, and that - scant - resources had to be dedicated for the fight against the pandemic.Copyright © 2023

Progress towards ending HIV transmission in England by 2030

Background: England is committed to ending HIV transmission by 2030. The HIV Action Plan (2021) set an interim ambition to reduce HIV transmission by 80% to 600 new diagnoses first made in England by 2025. Here we present the progress between 2019 (baseline) and 2021, interpreted in the context of the COVID-19 pandemic. Method(s): People newly diagnosed with HIV were reported to the HIV and AIDS Reporting Section (HARS). The annual number of people having an HIV test in all sexual health services (SHS) including online testing were reported using GUMCAD. HIV diagnoses among people previously diagnosed abroad were excluded (25%). Result(s): New HIV diagnoses first made in England fell by 32% from 2,986 in 2019 to 1,987 in 2020, but plateaued in 2021 (2,023). Among gay/bisexual men, HIV diagnoses plateaued in 2021 (721) after a fall of 45% between 2019 and 2020, from 1,262 to 699. After a fall in HIV testing in 2020 (from 156,631 in 2019 to 144,800 in 2020), the number of people tested in 2021 (178,466) exceeded pre-COVID-19 levels. This suggests a decline in HIV incidence supported by a CD4 back calculation model (80% probability of a decline for the period 2019-2021), but at a slowing rate. Among heterosexual adults, new HIV diagnoses first made in England in 2021 also plateaued (798) following a 31% decrease (from 1,109 in 2019 to 761 in 2020). However, HIV testing coverage has not recovered to pre- COVID-19 levels (628,607 in 2019, 441,017 in 2020 and 489,727 in 2021). This provides no evidence of a fall in incidence in this population. Conclusion(s): A reduction by 360 new diagnoses first made in England year on year from 2022 onwards is required to meet the HIV Action Plan ambition. Despite an estimated 4,500 people with undiagnosed HIV and extremely high levels of antiretroviral therapy and viral suppression, PrEP access remains unequal. HIV testing numbers, which were affected by COVID-19 pandemic, have recovered in gay/bisexual men, but not among heterosexual adults. While the interim ambition is within reach for gay/bisexual men, PrEP and testing levels must be scaled up in heterosexual adults.

Human Immunodeficiency Virus Infection and Acquired Immunodeficiency Syndrome

Human immunodeficiency virus (HIV)-1, the virus that causes HIV infection and acquired immunodeficiency syndrome (AIDS), has caused cases of infection recognized in the United States since the late 1970s. As scientists seek a cure for HIV, much has been learned about the interaction of the virus and the immune system. Recent advances in therapies used as tools for HIV treatment and prevention have resulted in a worldwide decrease in new infections, and public health campaigns are aimed at reducing new cases to a level signaling the end of the HIV epidemic. While organs and tissue systems may be damaged not only by HIV but also by the treatment of HIV with antiretroviral medications, people living with HIV can live a normal life span with appropriate medical management. The new epidemic affecting humankind, the novel coronavirus disease that emerged in 2019 (COVID-19) caused by the severe acute respiratory syndrome (SARS) coronavirus-2 (CoV-2), is disrupting HIV treatment and prevention programs worldwide and has laid bare health and healthcare disparities and inequalities existing in rich and poor countries alike. The effects of the COVID-19 pandemic on the HIV epidemic have yet to be realized. © 2023 Elsevier Ltd. All rights reserved.

Single-centre review of rapid antiretroviral therapy initiation during the COVID-19 pandemic

Background: BHIVA released interim guidance on first line anti-retroviral therapy (ART) initiation during the COVID-19 pandemic, when investigations/follow-up was restricted. Our HIV service didn't restrict follow-up but suspended in-house resistance testing (RT) due to laboratory capacity. Having prescribed 'rapid ART' based on the Northern Algorithm 01/08/2020-01/01/2022 we wanted to evaluate our prescribing during the pandemic. Method(s): All new HIV diagnoses 01/08/2020-31/12/2021 were identified via our HARS dataset. Retrospective casenote review identified ART prescribed, and switches that occurred upon baseline RT availability, to more suitable and/or cost-effective regimes. Result(s): 32 new diagnoses: 11 female, 21 male, median age 41 years (17-81), 10 MSM, 22 Heterosexuals, White British 14, African 9, other 7. Median time to ART initiation 10 days (0-210). Median CD4 count 359 (2-1251), 8 had CD4<200. 7/32 had Primary HIV infection, 5 initiating ART at 1st visit. 30/32 started ART within our service, 1 relocated, 1 initiated abroad. 28/30 started algorithm compliant rapid ART. Of the 2 that delayed, 1 had significant resistance, the other patient choice. 8/30 (27%) 'rapid ART' initiations switched post RT availability. Conclusion(s): All patients initiating ART in our service during the pandemic were algorithm compliant and fulfilled BHIVA recommendations. 7/10 starting Darunavir/ r-based therapy switched to Delstrigo post RT, a more cost-effective STR. Zero patients on Biktarvy switched post RT;implying it's difficult to switch patients from small INSTI-based-STRs. Future work includes comparing our results with other centres and reviewing ART switches post HIV National Prescribing Guide implementation. (Table Presented).

Some clinical and epidemiological aspects of the course of COVID-19 in people living with HIV

Objective. To describe the clinical and epidemical characteristics of a new coronavirus disease 2019 (COVID-19) in people living with HIV, for HIV infection implies the development of an immunosuppressive condition that may exacerbate the course of COVID-19. Material and methods. The research is based on retrospective and current epidemiological situation of HIV and SARS-CoV-2 infections in the Southern Russia regions during 2020 and survey of the patients with the co-infections concerning epidemiological, clinical, and laboratory diagnostic information. We collected all data from 15 regional centers for AIDS prevention and control in the Southern and North Caucasus Federal Districts. The survey sample consists of 121 patients. Statistical computation is done with Microsoft Office Excel 2010. Results and discussion. HIV patients of various age and social characteristics are involved in the COVID-19 epidemic process. Within registered HIV and SARS-CoV-2 co-infections all patients have apparent clinical symptoms. Asymptomatic cases are not presented. Mild cases prevail in the sample (48.8%). The frequency of severe and extremely severe was significantly higher in people living with HIV/AIDS on ART more than 2 months against naive PLHIV or using ART up two one month (p<0.05).Copyright © 2022 by the authors.

Clinical epidemiology of COVID-19 in Black people with HIV in south London, UK

Background: The COVID-19 pandemic disproportionally affected Black communities who were at greater risk of SARS-CoV-2 acquisition, morbidity, and mortality than those of White ethnicity. We describe the clinical epidemiology of COVID-19 in the GEN-AFRICA cohort of Black people with HIV in two South London clinics. Method(s): First reported episodes of COVID-19 up to 12/2021 were ascertained by direct questioning and/or medical records review. The cumulative incidence of COVID-19 and vaccination was determined by Nelson- Aalen methods. Pre-pandemic immunovirological and comorbidity status obtained prior to 01/2020 was used to identify risk factors for COVID-19 using Cox regression. We compared characteristics of participants with mild/ moderate (not requiring hospitalization) and severe (requiring hospitalization or resulting in death) COVID-19. Result(s): COVID-19 status was available for 1184 (95%) of 1289 GEN-AFRICA participants (mean age 49.1 years;55% female;median CD4 565;93% HIV RNA <200), and SARS-CoV-2 vaccination status for 1160;998 (86%) had received at least one vaccine dose (administered to 50% by 16/02/2021). A total of 310 participants (26.2%) reported a first episode of COVID-19 (any severity), with a cumulative incidence of 6%, 14%, 15% and 22% following the initial, alpha, delta, and omicron waves. Women, people of East African ancestry, and those with detectable HIV RNA were more likely to report COVID-19 (Table). CD4 (current/nadir), class of antiretroviral therapy (ART), and comorbidity status were not associated with COVID-19. Findings were similar when restricted to episodes in 2020 (prior to vaccine availability) or testconfirmed COVID-19. Severe COVID-19 cases (N=34) were more often male (p=0.002), of West-African ancestry (p=0.01), with lower CD4 cell counts (p=0.002), and they more often had a history of AIDS, diabetes mellitus, cardiovascular disease, and chronic kidney disease (all p=0.001) compared to mild/moderate cases;they were also more likely to be on protease inhibitor (PI)- containing ART (p=0.01). Conclusion(s): By the end of the second year of the pandemic, 22% of black people with HIV in South London had experienced COVID-19. Immune and comorbidity status were not associated with COVID-19 when all cases were considered but strongly associated with severe COVID-19 disease, as were West-African ancestry and being on a PI. (Table Presented).

Features of the diagnosis and course of COVID-19 in HIV-infected patients hospitalized in a hospital

The global pandemic of coronavirus infection (COVID-19) has set complex diagnostic tasks for doctors of polyclinics and hospitals. Considering the simultaneous pandemic spread of two infectious diseases - COVID-19 and HIV infection, the problem of studying the clinical features of combined COVID-19/HIV infection becomes urgent. The aim of the study was to determine the features of the diagnosis and course of COVID-19 against the background of HIV infection in patients undergoing inpatient treatment. Material and methods. The study was conducted on the basis of the temporary Clinical Medical Center COVID-19 of the A.I. Yevdokimov Moscow State University of Medicine and Dentistry of the Ministry of Healthcare of the Russian Federation in Moscow from October 2020 to January 2022. The study included 31 233 patients with COVID-19 complicated by pneumonia. To analyze the features of the course of combined COVID-19/HIV infection, a group of 51 HIV-infected patients was identified. The diagnosis of COVID-19 was determined based on the detection of SARS-CoV-2 RNA by PCR in nasal/oropharyngeal smears and/or according to computed tomography of the lungs (CT). During the study, age, gender, anamnesis, objective examination data were analyzed, taking into account the results of CT scans of the chest organs, data from routine laboratory blood tests, oxygen support regimens, treatment outcomes and duration of detection of SARS-CoV-2 RNA. All patients were treated according to the Temporary Clinical Guidelines for the Diagnosis and Treatment of COVID-19, 14 version dated 12/27/2021. Results. The number of patients with combined HIV infection and SARS-CoV-2 out of the total number of hospitalized COVID-19 patients (n=31 233) was 0.16%. Upon admission, 30 (59%) patients reported having HIV infection and receiving antiretroviral therapy (ART). HIV infection was first diagnosed in 21 patients at 2-3 weeks of inpatient treatment. The average age of patients with SARS-Cov-2/HIV co-infection was 1.5 times less than in patients without HIV (41.1+/-5.3 and 64.4+/-10.1, respectively) (p<=0.05). Concomitant pathology (hypertension, type 2 diabetes mellitus, chronic kidney disease and chronic lung diseases) was less common (51%) in the group of combined infection than in the group without HIV (83%). However, in 41% of patients with coinfection, chronic viral hepatitis B, C was detected, in contrast to 0.3% of cases of COVID-19 patients without HIV. 26 (51%) patients were discharged with improvement, while the average bed-day did not differ from patients without HIV infection (13.4+/-4.5 days and 11.7+/-5.2, respectively) (p>=0.05). 7 (24%) patients at the time of discharge (16.8+/-4.2 days) with clinical and laboratory improvement maintained a positive result of PCR RNA on SARS-Cov-2. In 22 (43%) patients with coinfection, hospitalization was fatal for 3 to 21 days of treatment, with ARDS with respiratory and multiple organ failure, which is 3.6 times higher than in patients without HIV infection. The analysis showed that, regardless of the result of PCR on SARS-CoV-2 RNA, in non-specialized hospitals, HIV testing is indicated for young patients with fever for more than 14 days, with lung damage in the form of bilateral interstitial changes according to CT, a history of chronic hepatitis C, B, with progressive severity of the condition on against the background of COVID-19 therapy. Early consultation of an infectious disease specialist, examination of sputum/lavage by PCR for pathogens of opportunistic infections and the appointment of ART and drugs for the treatment of opportunistic diseases will improve the quality of medical care for patients in a non-core HIV hospital will improve the prognosis of COVID-19.Copyright © Eco-Vector, 2022.

HIV care during the SARS-COV-2 pandemic for Black people with HIV in the UK

Background: The COVID-19 pandemic disproportionally affected black communities but the impact on HIV care in this group remains poorly understood. We evaluated measures of HIV care during the COVID-19 pandemic in the GEN-AFRICA cohort of black people with HIV living in the U.K. Method(s): We evaluated interruptions to HIV care during the COVID-19 pandemic (01/2020-09/2022) in the GENAFRICA cohort at nine UK clinics who provided HIV outcomes for >80% of their participants. We ascertained death, transfers of care, loss to follow up for >12 months, the highest HIV viral load and interruptions to antiretroviral therapy (ART). We evaluated factors associated with the composite outcome of HIV viraemia (viral load >200 c/mL) and/or an ART interruption using logistic regression analysis;factors associated (P<0.1) in univariable analysis were included in the multivariable model. We also summarized reasons for ART interruptions where recorded. Result(s): 2321 participants (mean age 51.3 years;55.8% women;pre-pandemic current/nadir CD4 of 500/204 cells/mm3 and HIV RNA <200 c/mL in 92.3%) were in care on 01/01/2020. Thirty (1.3%) subsequently died, 24 (1.0%) transferred care and 48 (2.1%) became lost to follow up. 523 (22.7%) reported an episode of COVID-19 and 1771 (87.1%) having been vaccinated against SARSCoV- 2. The composite outcome could be evaluated in 2130 (91.8%);259 (11.2%) had a documented HIV VL >200 c/mL, 228 (9.8%) an ART interruption and 325 (14%) had HIV viraemia/ART interruption. In multivariable analysis, older age, a pre-pandemic HIV RNA <200 c/mL and being vaccinated against SARS-CoV-2 were associated with reduced odds of HIV viraemia/ART interruption (Table) while sex, CD4 (current/nadir), comorbid status and having had COVID-19 were not associated. Reasons for ART interruption were available for 52 participants;38% cited domestic logistic reasons, 27% issues related to foreign travel, 19% psychological reasons, 12% lockdown or changes to the daily routine and 4% personal choice. Conclusion(s): During the COVID-19 pandemic, one in seven black people with HIV experienced an ART interruption and/or HIV viraemia. Pre-pandemic measures of suboptimal engagement in care, pandemic restrictions, and wider health beliefs as reflected by COVID-vaccination, contributed to these undesirable HIV outcomes.

Impact of Covid-19 Induced Program Adaptations on Hiv Suppression in Three Countries

Background: The pandemic response measures have had significant global economic and health impacts with transient reductions in HIV clinic attendance and self-reported anti-retroviral therapy (ART) adherence reported in prior studies. Since viral suppression (VS) is an indication of ART adherence and effective service delivery, we assessed VS in the context of the COVID-19 pandemic in 3 African countries Methods: Since 2013, the African Cohort Study (AFRICOS) has enrolled individuals 18 years or older with and without HIV, in an approximate 5:1 ratio, at 12 clinics across 5 HIV care programs in Tanzania Uganda, Kenya, and Nigeria. For people living with HIV (PLWH), ART history was extracted from medical records and viral load was assessed at each visit. This assesses VS (< 1000 c/ml) before and during the COVID-19 pandemic (categorized into 4 surges and a consolidated non-surge period;defined in Table 1) among PLWH. Tanzania was excluded due to inadequate pandemic data. Logistic regression with generalized estimating equations, clustered by participant, was used to estimate odds ratios (ORs) and 95% confidence intervals (CI) comparing VS before and during COVID-19. Models are adjusted for age, sex, and program. Result(s): Of the 1741 study participants, 368 are from Uganda, 1156 are from Kenya, and 217 are from Nigeria;730 are males, 1011 are females, and 147 are under the age of 30. PLWH were less likely to be virally suppressed during the first surge period (OR 0.85, CI 0.46-1.56), but VS significantly increased during the second surge period (OR 1.95, CI 1.23-3.04) compared to the pre-COVID period. The third and fourth surge periods also saw a higher VS (table 1). Females are more likely to be virally suppressed than males (OR 1.58, CI 1.09- 2.29) and PLWH ages 40-49 have higher VS (OR 2.43, CI 1.32-4.48) compared to PLWH under. PLWH at the AFRICOS sites in Kenya and Nigeria show lower VS than the Ugandan cohort (ORs 0.46, CI 0.26-0.79 and OR 0.32, CI 0.17-0.60 respectively). Conclusion(s): The initial drop in VS may be attributed to reduced clinic access due to lockdowns. Many HIV programs supported by the President's Emergency Plan for AIDS Relief (PEPFAR) adapted their strategies to serve PLWH by scaling up community ART dispensing and multi-month dispensing (MMD) of ART for stable clients, which could have led to increased VS during the other surge periods.
