Could presepsin be an alternative marker in the early diagnosis of sepsis in COVID-19?

In critical patients with Coronavirus Disease (COVID-19), we investigated the diagnostic value of presepsin in the early diagnosis of superinfection with sepsis, and the effect of antibiotic treatment (AT) in the levels of presepsin and procalcitonin and C-reactive protein. A total of 68 critical patients with sepsis and septic shock in the intensive care unit and 20 outpatients (control group) with COVID-19 were taken. ICU patients (n = 68) were further divided into three groups. C(-)AT(-) had negative blood or tracheal aspirate cultures (C) and not AT on admission to ICU (n = 18), C(-)AT(+) had negative C and AT on admission to intensive care unit (n = 31) and C(+) had positive C (n = 19). Presepsin, procalcitonin, C-reactive protein results were compared between the groups. There were no significant relationships between presepsin levels with sepsis, septic shock, mortality, or length of stay in ICU in patients with COVID-19. For procalcitonin and C-reactive protein levels in C(-)AT(+) and C(+) groups were significantly higher than in control and C(-)AT(-) groups (p < .001). C-reactive protein levels in C(-)AT(-) group were significantly higher than in the control group (p < .001). PCT and CRP, there was no difference between C(-)AT(+) and C(+) groups, and procalcitonin there was no difference between control and C(-)AT(-) groups. Presepsin was not found as a useful biomarker for the prediction of sepsis in COVID-19 patients. These study findings indicate that procalcitonin and C-reactive protein may be an indicator of an early diagnostic marker for superinfection in critical COVID-19 patients.

The Course of COVID-19 in Four Patients with HIV During the Pandemic.

BACKGROUND: The clinical spectrum of SARS-CoV-2 infection may vary from simple colds to a severe acute respiratory syndrome, metabolic acidosis, septic shock, and multiple organ failure. Current evidence indicates that the risk of severe illness increases with age, in the male sex, and with certain chronic medical problems. Many people living with HIV have other conditions that increase their risk. ; Case presentation: In the first 3 months of the pandemic, four patients with HIV were hospitalized in our clinic because of COVID-19. The disease severity was mild in two patients with normal CD4+ T count. However, one patient with a low CD4+T count died and the other developed retinal detachment one month after discharge. The deceased patient had a malignancy. ; Conclusion: In this study, the effect of the immunological status of the patients on the course of COVID-19 and the developing vascular complications was evaluated in 4 patients with HIV.
