AbstractTo estimate the level of community exposure to SARS-CoV-2 in Ghana, we conducted phased seroprevalence studies of 2729 participants in selected locations across Ghana. Phase I screening (August 2020) covered a total of 1305 individuals screened at major markets/lorry stations, major shopping malls, hospitals and research institutions involved in COVID-19 work. The screening was performed using a strip-in-cassette lateral flow type Rapid Diagnostic Test (RDT) kit that simultaneously and separately detected IgM and IgG antibodies against SARS-CoV-2 nucleocapsid protein. In Phase I, 252/1305 (19%) tested positive for IgM or IgG or both. Exposure rate was significantly higher among individuals tested at markets/lorry stations (26.9%) compared to those at Shopping Malls (9.4%). The 41–60-years age group had the highest exposure rate (27.2%). People with only a basic level or no formal education had a higher exposure rate (26.2%) than those with tertiary level education (13.1%); and higher in informally employed workers (24.0%) than those in the formal sector (15.0%). Phases II and III screening activities in October and December 2020, respectively, showed no evidence of increased seroprevalence, indicating either a reduced transmission rate or loss of antibody expression in a subset of the participants. The Upper East region has the lowest exposure rate, with only 4 of 200 participants (2%) seropositivity. Phase IV screening in February 2021 showed that exposure rates in the upper income earners (26.2%) had almost doubled since August 2020, reflective of Ghana’s second wave of symptomatic COVID-19 cases, which began in December 2020. The Phase IV results suggest that seroprevalence levels have become so high that the initial socioeconomic stratification of exposure has been lost. Overall, the data indicates a much higher COVID-19 seroprevalence in the Greater Accra Region than was officially acknowledged, likely implying a considerably lower case fatality rate than the current national figure of 0.84%. Additionally, the high exposure levels seen in the communities suggest that COVID-19 in Ghana still predominantly presents with none-to-mild symptoms. Our results lay the foundation for more extensive SARS-CoV-2 surveillance in Ghana and the West African sub-region, including deploying rapid antigen test kits in concert to determine the actual infection burden since antibody development lags infection.

Background: The Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) is an ongoing case-control study of spontaneous ICH among non-hispanic whites, non-hispanic blacks, and Hispanics. Prior studies have identified hypertension as a greater risk for non-lobar (NL) ICH as compared with lobar (L) ICH. Given the greater reported prevalence of hypertension among black and Hispanic populations, we hypothesized that the location of ICH may differ by race/ethnicity. Methods: At the time of this analysis, we had ICH location data, lobar vs. non-lobar, on 648 subjects. We performed univariate analysis on known and potential predictors of ICH location: age, sex, race/ethnicity, hypertension, diabetes, BMI, creatinine, cholesterol, aspirin use, smoking, alcohol use, caffeine use, and INR. INR was dichotomized at >1.1. After forcing in age, sex, race, history of diabetes, aspirin use and INR, we added significant and near-significant (p<0.2) variables in a stepwise fashion to complete our final logistic regression model. Our outcome measure was lobar ICH. Conditional pairwise testing was performed for race/ethnicity. Results: Of the 648 subjects (mean age 61.12 ± 14.51 years; 39.8% female; 35.0% Hispanic, 26.5% white, 38.4% black), 181 (27.9%) presented with lobar ICH. Hypertension was present in 525 subjects (75.1% L, 83.3% NL; p=.018), diabetes in 152 (26.0% L, 22.5% NL; p=.348), high cholesterol in 244 (45.9% L, 34.5% NL; p=.008), aspirin use in 200 (37.0% L, 28.5% NL; p=.035), and INR >1.1 (24.1% L, 21.8% NL; p=.535) In our final model, race/ethnicity (p<.024) was associated with location of ICH. Furthermore, white race/ethnicity was associated with L ICH, compared with black (b=.57, p=.016) or Hispanic (b=.56, p=.018). Hypertension (b=-0.63, p=.009) was associated with NL ICH, and smoking (b=0.51, p=.007) was associated with L ICH. Discussion: Our results suggest that there are significant racial/ethnic differences in the distribution of lobar and non-lobar ICH. The conditional pairwise testing for race/ethnicity showed a significantly higher rate of lobar ICH in whites, compared with blacks or Hispanics. These findings are intriguing given the differences in case-fatality rates and age at ICH onset.

Background and Purpose: lymphopenia is increasingly recognized as a consequence of acute illness and may predispose to infections. We investigated whether admission lymphopenia (AL) is associated with increased risk of infectious complications and poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). Methods: we analyzed a prospectively collected cohort of ICH patients ascertained between 1994 and 2015. Subjects were included if they had a lymphocyte count obtained within 24 h from onset and AL was defined as lymphocyte count<1000/uL. Infectious complications were assessed through retrospective chart review and the association between AL, infectious complications and mortality was investigated with a multivariable Cox regression and logistic regression respectively. Results: 2014 patients met the inclusion criteria (median age 75, males 54.0%) of whom 548 (27.2%) had AL and 605 (30.0%) experienced an infectious complication. Overall case fatality at 90 days was 36.9%. Patients with AL were more severely affected, as highlighted by larger hematoma volume, higher frequency of intraventricular hemorrhage and lower Glasgow Coma Scale score (all p<0.001). AL was independently associated with increased risk of pneumonia (Hazard Ratio [HR] 1.65, 95% confidence interval [CI] 1.32-2.05, p<0.001) and multiple infections (HR 1.75, 95% CI 1.22-2.51, p=0.002). The association with urinary tract infection, sepsis or other infections was not significant. AL was also an independent predictor of 90-day mortality (odds ratio 1.55, 95% CI 1.18-2.04, p=0.002) after adjusting for confounders. Conclusions: AL is common in ICH and associated with increased risk of infectious complications and poor outcome. Further studies will be needed to determine whether prophylactic antibiotics in ICH patients with AL can improve outcome.

Background: The use of oral anticoagulants (OAC) is associated with poor outcome in intracerebral hemorrhage (ICH). In this study we investigated the effect of delayed INR reversal and the factors influencing it in patients with OAC-associated ICH (OAC-ICH). Methods: Data were obtained from the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study which is a prospective, multi-ethnic multicenter study of ICH. Exclusion criteria included missing initial hematoma volume, INR or ED arrival time and being on heparin. Baseline characteristics, INR at baseline and 12h, hematoma location and volume, treatment received, hematoma expansion at 24h, and mortality at 3 months were recorded. INR reversal was defined as INR<1.4 at 12h post admission. Variables associated with INR reversal and case fatality at 3 months in non-OAC users and OAC users with and without INR <1.4 were compared. Results: A total of 1,746 of 2,276 subjects were included in the analysis. A higher proportion of OAC users (n=185) were white and had hypertension, diabetes, hypercholesterolemia, and lobar ICH than non-users (P<0.05). Baseline INRs for the OAC group were 3.1 (28.7%). Subjects on OAC received fresh frozen plasma (FFP, 44%) monotherapy, either recombinant factor VII or prothrombin complex (FVII/PCC, 7%), or a combination of FFP/FVII/PCC (11%). Increasing age (OR=0.96, 95% CI 0.94-0.98), elevated baseline INR (OR=0.34, 95% CI 0.26-0.43), and use of FFP only (OR=0.07, 95% CI 0.04-0.13) was associated with lack of INR reversal at 12h. Median INR at 12h (IQR) were 1.4 (1.3-1.6), 1.1 (0.9-1.1), and 1.0 (1.0-1.3) for the FFP, PCC/FVII, and FFP/FVII/PCC groups, respectively (p1.4 did not influence the rate of hematoma expansion at 24h. Case fatality at 3 months was 22% for non-OAC-ICH, 34% for OAC-ICH with INR<1.4, and 44% for OAC-ICH with INR>1.4 (p=.0005). Conclusion: In the ERICH study, patients treated with FFP monotherapy were less likely to have a normalized INR at 12h and this was associated with increased case fatality at 3 months. The use of FVII/PCC may shorten time to INR correction and improve outcome in OAC-ICH.
