Abstract
BACKGROUND While acute SARS-CoV-2 infection and associated inflammation resulted in substantial morbidity and mortality during the COVID-19 pandemic, particularly in unvaccinated patients, long-term effects of SARS-CoV-2 exposure for reactivation of latent oncogenic herpesviruses, such as KSHV, is unknown. METHODS We performed a longitudinal observational cross-sectional study on 407 non-hospitalised adult HIV-infected (CD4 count <350 cells/μL) patients attending antiretroviral therapy services in Gugulethu, South Africa, from October 2020 to April 2023. FINDINGS KSHV seroprevalence was 53.5%; the quarterly SARS-CoV-2 seroprevalence increased from 76.2% (before roll-out of COVID-19 vaccinations) to 94.9%, with 32.2% being self-reportedly vaccinated against COVID-19. Over the course of recruitment, the quarterly percentage of patients with detectable KSHV viral load (VL) in the peripheral blood increased from 3.3% to 69.2%. The presence of KSHV VL was significantly associated with SARS-CoV-2 RBD antibody titers in unvaccinated (median RBD IgG OD 1.24 [IQR 0.82-2.42] in non-reactivated versus 2.83 [IQR 1.08-4.72] in reactivated patients, p = 0.0030) but not in vaccinated patients (median RBD IgG OD 5.13 [IQR 4.11-6.36] in non-reactivated versus 4.53 [IQR 2.90-5.92] in reactivated patients, p = 0.086). Further logistic regression revealed significantly higher odds of KSHV reactivation in unvaccinated, previously SARS-CoV-2 exposed patients (p = 0.015, adjusted OR 1.28 [95% CI: 1.05-1.55]), but not vaccinated patients (p = 0.080, adjusted OR 0.83 [95% CI: 0.67-1.02]). Interestingly, detectable KSHV VL was not associated with increased inflammatory markers such as C-reactive protein and interleukin-6. INTERPRETATION High, and most likely repeated, exposure to SARS-CoV-2 in unvaccinated individuals may have long-term consequences for reactivation of KSHV infection as shown here in the context of HIV-infected patients with impaired immune functions. Post-pandemic prevention and/or monitoring strategies of potential KSHV-associated pathologies in high-risk patients with immunodeficiencies are therefore highly recommended. FUNDING This research was funded by the EDCTP2 programme (Training and Mobility Action TMA2018SF-2446).

Abstract
BackgroundGlobally, the most significant risk factors for adverse COVID-19 outcome are increasing age and cardiometabolic comorbidities. However, underlying coinfections may modulate COVID-19 morbidity and mortality, particularly in regions with high prevalence of infectious diseases.MethodsWe retrospectively analyzed serum samples for IgG antibodies against the common circulating coronaviruses HCoV-NL63, HCoV-229E, HCoV-OC43 and HCoV-HKU1 from non-hospitalized and hospitalized confirmed COVID-19 patients recruited during the first (June-August 2020) and second (October 2020-June 2021) COVID-19 wave in Cape Town, South Africa. Patients were grouped according to COVID-19 disease severity: Group 1: previously SARS-CoV-2 infected with positive serology and no symptoms (n=94); Group 2: acutely SARS-CoV-2 infected, hospitalized for COVID-19 and severe symptoms (n=92).ResultsThe overall anti-HCoV IgG seroprevalence in the entire patient cohort was 60.8% (95% CI: 53.7 – 67.8), with 37.1% HCoV-NL63 (95% CI: 30 – 44), 30.6% HCoV-229E (95% CI: 24 – 37.3), 22.6% HCoV-HKU1 (95% CI: 16.6 – 28.6), and 21.0% HCoV-OC43 (95% CI: 15.1 – 26.8). We observed a significantly higher overall HCoV presence (72.3% versus 48.9%) and coinfection frequency (43.6% versus 19.6%) in group 1 compared to group 2 patients with significantly higher presentation of HCoV-NL63 (67.0% versus 6.6%) and HCoV-HKU1 (31.1% versus 14.1%). However, only antibody titers for HCoV-NL63 were significantly higher in group 1 compared to group 2 patients (p< 0.0001, 1.90 [95% CI: 0.62 – 2.45] versus 1.32 [95% CI: 0.30 – 2.01]) which was independent of the participants’ HIV status. Logistic regression analysis revealed significantly protective effects by previous exposure to HCoV-NL63 [p< 0.001, adjusted OR = 0.0176 (95% CI: 0.0039 – 0.0786)], while previous HCoV-229E exposure was associated with increased COVID-19 severity [p = 0.0051, adjusted OR = 7.3239 (95% CI: 1.8195–29.4800)].ConclusionWe conclude that previous exposure to multiple common coronaviruses, and particularly HCoV-NL63, might protect against severe COVID-19, while no previous HCoV exposure or single infection with HCoV-229E might enhance the risk for severe COVID-19. To our knowledge, this is the first report on HCoV seroprevalence in South Africa and its possible association with cross-protection against COVID-19 severity.

Abstract
In South Africa, high exposure to SARS-CoV-2 occurs primarily in densely populated, low-income communities, which are additionally burdened by highly prevalent Human Immunodeficiency Virus (HIV). With the aim to assess SARS-CoV-2 seroprevalence and its association with HIV-related clinical parameters in non-hospitalized patients likely to be highly exposed to SARS-CoV-2, this observational cross-sectional study was conducted at the Gugulethu Community Health Centre Antiretroviral clinic between October 2020 and June 2021, after the first COVID-19 wave in South Africa and during the second and beginning of the third wave. A total of 150 adult (median age 39 years [range 20−65 years]) HIV-infected patients (69% female; 31% male) were recruited. 95.3% of the cohort was on antiretroviral therapy (ART), had a median CD4 count of 220 cells/µL (range 17−604 cells/µL) and a median HIV viral load (VL) of 49 copies/mL (range 1−1,050,867 copies/mL). Furthermore, 106 patients (70.7%) were SARS-CoV-2 seropositive, and 0% were vaccinated. When stratified for HIV VL, patients with uncontrolled HIV viremia (HIV VL > 1000 copies/mL) had significantly higher odds of SARS-CoV-2 seropositivity than patients with HIV VL < 1000 copies/mL, after adjusting for age, sex and ART status (p = 0.035, adjusted OR 2.961 [95% CI: 1.078−8.133]). Although the cause−effect relationship could not be determined due to the cross-sectional study design, these results point towards a higher risk of SARS-CoV-2 susceptibility among viremic HIV patients, or impaired HIV viral control due to previous co-infection with SARS-CoV-2.

Abstract
BACKGROUND HIV and tuberculosis (TB) independently cause an increased risk for venous thromboembolic disease (VTE): deep vein thrombosis (DVT) and/or pulmonary embolism (PE). Data from high HIV and TB burden settings describing VTE are scarce. The Wells' DVT and PE scores are widely used but their utility in these settings has not been reported on extensively. OBJECTIVES To evaluate new onset VTE, compare clinical characteristics by HIV status, and the presence or absence of TB disease in our setting. We also calculate the Wells' score for all patients. METHODS A prospective cohort of adult in-patients with radiologically confirmed VTE were recruited into the study between September 2015 and May 2016. Demographics, presence of TB, HIV status, duration of treatment, CD4 count, viral load, VTE risk factors, and parameters to calculate the Wells' score were collected. RESULTS We recruited 100 patients. Most of the patients were HIV-infected (n=59), 39 had TB disease and 32 were HIV/TB co-infected. Most of the patients had DVT only (n=83); 11 had PE, and 6 had both DVT and PE. More than a third of patients on antiretroviral treatment (ART) (43%; n=18/42) were on treatment for <6 months. Half of the patients (51%; n=20/39) were on TB treatment for <1 month. The median (interquartile range (IQR)) DVT and PE Wells' score in all sub-groups was 3.0 (1.0 - 4.0) and 3.0 (2.5 - 4.5), respectively. CONCLUSION HIV/TB co-infection appears to confer a risk for VTE, especially early after initiation of ART and/or TB treatment, and therefore requires careful monitoring for VTE and early initiation of thrombo-prophylaxis.

Abstract
Understanding of the burden of HIV infection and comorbid conditions in older adults is limited, especially in low- and middle-income countries. Antiretroviral therapy (ART) has increased longevity of HIV-positive individuals, making age-related comorbidities more likely. This study aimed to compare the demographic and disease profiles, including chronic comorbid conditions of inpatients, at least 50 years of age, by HIV status, admitted to a regional hospital in South Africa. Adults, 50 years of age and older, admitted to internal medicine wards from November 2015 to February 2016 were approached to participate. Sociodemographic data, laboratory results, anthropometric data, discharge diagnoses, and HIV status were collected and compared by HIV serostatus. Overall, 151 participants were enrolled. Their median age was 61 years (IQR: 56-68 years); 89 (58.9%) were women. Overall, 47 (31.1%) were HIV positive, of whom 10 (6.6%) were first diagnosed during the admission. HIV-positive inpatients were younger than HIV-negative patients. The leading discharge diagnoses of all participants were acute gastroenteritis (11.5%) and community-acquired pneumonia (11.5%). Hypertension and type 2 diabetes mellitus (T2DM) were the leading comorbidities in both HIV-negative and HIV-positive participants. Prevalence of hypertension was 75.0% in seronegative, 59.5% in those with a prior diagnosis of HIV, and 40.0% in newly diagnosed; similarly, prevalence of T2DM was 22.1% in HIV-negative and 24.3% in known HIV-positive participants. Similar proportions died during admission; 11.3% of HIV-negative and 12.7% of HIV-positive admitted inpatients died. Almost one third of patients admitted were HIV positive. In HIV-positive older admitted to hospital, the leading cause for hospitalization was coinfections. In the ART era, irrespective of HIV status, older patients have similar age-related chronic illnesses and similar mortality rates, despite younger age at admission.
