Background Clinical characteristics, including laboratory parameters, of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant have been limited. Methods This retrospective case-control study was conducted in a single hospital. Patients with disease 2019 (COVID-19) who visited Asahikawa City Hospital outpatient department as new patients and underwent blood tests were included this study. We analyzed data from January 2022 to April during phase 2021 October Delta phase. treated at other hospitals after visiting our hospital excluded.

This study aimed to compare the clinical picture of COVID-19 in initial and later period Omicron dominance identify populations still at risk. A retrospective comparison data 965 patients hospitalized during early Omicron's (EO, January-June 2022) with 897 from a (LO, July 2022-April 2023) SARSTer database was performed. Patients LO, compared EO, were older, had better condition on admission, lower need for oxygen mechanical ventilation, less frequent lung involvement imaging, showed much faster improvement. Moreover, overall mortality EO 14%, higher than that LO-9%. Despite milder course disease, exceeding 15% similar both groups among involvement. The accumulation risk factors such as an age 60+, comorbidities, involvement, saturation <90% resulted constant 98% patients, 8% 30% rate LO period. Multiple logistic regression revealed odds death phase. infections caused by currently dominant subvariants, prophylaxis is necessary people over 60 years age, especially those case pneumonia respiratory failure.

The aim of this study was to analyze the serum concentration interleukin-6 (IL-6), C-reactive protein (CRP), D-dimer, lactate dehydrogenase (LDH), ferritin, and procalcitonin in COVID-19 patients with different forms disease. We performed a prospective cohort on 137 consecutive patients, divided into four groups according severity disease as follows: 30 mild form group, 49 moderate 28 severe critical group. tested parameters were correlated severity. Significant differences registered between depending vaccination status, LDH concentrations virus variant, IL-6, CRP, ferritin status gender. ROC analysis revealed that D-dimer best predicted variant. Our findings confirmed interdependence relationships observed inflammation markers relation clinical COVID-19, all biomarkers increasing COVID-19. LDH, increased forms.

About four years have passed since the detection of first cases COVID-19 in China. During this lethal pandemic, millions people lost their lives around world. Since waves infection, various pharmacotherapeutic agents been examined management COVID-19. Despite all these efforts pharmacotherapy, drug repurposing, and design development new drugs, multiple organ involvement complications occurred during Some became chronic long-lasting which led to "long COVID" syndrome appearance. Therefore, best way eradicate pandemic is prophylaxis through mass vaccination. In regard, vaccine platforms including inactivated vaccines, nucleic acid-based vaccines (mRNA DNA vaccines), adenovirus-vectored protein-based subunit designed developed prevent or reduce hospitalization, mortality rates. focused review, at first, most commonly reported clinical presentations summarized. addition, different therapeutic regimens latest status listed. Furthermore, related signs, symptoms, mentioned. At end, effectiveness available with against early SARS-CoV-2 variants currently circulating interest (VOI) necessity booster shots summarized discussed more detail.
