Prevalence of Anti-SARS-CoV-2 Antibodies in HIV-Positive Patients in Wroclaw, Poland-Unexpected Difference between First and Second Wave

Background: The presence and level of anti-SARS-CoV-2 antibodies in PLWH from the Lower Silesia region in Poland. Material and Methods: A total of 216 serum samples of both sexes, aged 21-77, and treated with TDF or TAF together with FTC and INSTI at two points of time. Anyone who did not experience COVID-19 symptoms. Samples were checked for the presence and levels of anti-SARS-CoV-2 antibodies regarding CD4 + T and CD8 + T cells counts, the ratio of these cells, age, sex, VL, and type of tenofovir used. Results: The average level and prevalence of anti-SARS-CoV-2 antibodies during the first wave were 65.81 IU/mL and 4.17%, while during the second wave, they were 125.98 IU/mL and 14.29%, respectively. There was a significant correlation between the number and type of lymphocytes and the presence of anti-SARS-CoV-2 antibodies. We did not find the same correlation regarding anti-SARS-CoV-2 levels. The average level of antibodies was higher during the second wave. There was no difference between the type of tenofovir used and the humoral response, as well as no correlation of anti-SARS-CoV-2 levels with age, gender, or VL. Conclusion: PLWH can have asymptomatic SARS-CoV-2 infection, which can influence the presence, but not levels, of anti-SARS-CoV-2 Ab. No correlation with type of tenofovir was observed.

Remdesivir Decreases Mortality in COVID-19 Patients with Active Malignancy.

Data on the use of remdesivir, the first antiviral agent against SARS-CoV-2, are limited in oncologic patients. We aimed to analyze contributing factors for mortality in patients with malignancies in the real-world CSOVID-19 study. In total, 222 patients with active oncological disorders were selected from a nationwide COVID-19 study of 4890 subjects. The main endpoint of the current study was the 28-day in-hospital mortality. Approximately half of the patients were male, and the majority had multimorbidity (69.8%), with a median age of 70 years. Baseline SpO2 < 85% was observed in 25%. Overall, 59 (26.6%) patients died before day 28 of hospitalization: 29% due to hematological, and 20% due to other forms of cancers. The only factor increasing the odds of death in the multivariable model was eGFR < 60 mL/min/m2 (4.621, p = 0.02), whereas SpO2 decreased the odds of death at baseline (0.479 per 5%, p = 0.002) and the use of remdesivir (0.425, p = 0.03). This study shows that patients with COVID-19 and malignancy benefit from early remdesivir therapy, resulting in a decrease in early mortality by 80%. The prognosis was worsened by low glomerular filtration rate and low peripheral oxygen saturation at baseline underlying the role of kidney protection and early hospitalization.

Impact of Kidney Failure on the Severity of COVID-19.

BACKGROUND: Patients with kidney failure are at an increased risk of progression to a severe form of coronavirus disease 2019 (COVID-19) with high mortality. The current analysis was aimed to assess the impact of renal failure on the severity of COVID-19 and identify the risk factors of the fatal outcome in this population. METHODS: The analysis included patients from the SARSTer database, a national real-world study evaluating treatment for COVID-19 in 30 Polish centers. Data were completed retrospectively and submitted online. RESULTS: A total of 2322 patients were included in the analysis. Kidney failure was diagnosed in 455 individuals (19.65%), of whom 373 presented moderate stage and 82 patients, including 14 dialysis individuals, presented severe renal failure. Patients with kidney failure were significantly older and demonstrated a more severe course of COVID-19. The age, baseline SpO2, the ordinal scale of 4 and 5, neutrophil and platelet count, estimated glomerular filtration rate, and C-reactive protein concentration as well as malignancy and arterial hypertension were the independent predictors of 28-day mortality in logistic regression analysis. CONCLUSIONS: Underlying kidney disease in patients with COVID-19 is among the leading factors associated with a higher risk of severe clinical presentation and increased mortality rate.

Convalescent Plasma Transfusion for the Treatment of COVID-19-Experience from Poland: A Multicenter Study.

Because the optimal treatment for COVID-19 is still unknown, it is important to explore every potential way of improving the chances of survival for COVID-19 patients. The aim of the study was to analyze the effectiveness of convalescent plasma on COVID-19 patients. The study population consisted of 78 patients diagnosed with COVID-19, selected from the SARSTer national database, who received convalescent plasma. The impact on clinical and laboratory parameters was assessed. A clinical improvement was observed in 62 (79%) patients, and 10 (13%) patients died from COVID-19. No side effects of the convalescent plasma treatment were observed. When plasma was administered earlier than 7 days from diagnosis, the total hospitalization time was shorter (p < 0.05). Plasma efficacy was inferior to remdesivir in endpoints such as the necessity and duration of oxygen therapy, the duration of hospitalization, and mortality rate, and inferior to other drugs in the case of the duration of hospitalization and the necessity of constant oxygen therapy, but comparable in most other measured endpoints. A comparison of a 30-day mortality rate in patients who received plasma and remdesivir (4/25, 16%) and who received only plasma (6/53, 11%) showed no significant difference. Convalescent plasma efficacy is inferior to remdesivir when treating COVID-19 patients but the addition of remdesivir to plasma does not improve the treatment effectiveness. In most endpoints, plasma was comparable to other treatment options. In our opinion, convalescent plasma may be used as a supportive treatment in COVID-19 patients because of the low frequency of adverse effects and availability, but must be given as early from the diagnosis as possible.
