Objectives: We aimed to determine serum angiotensin II levels in patients with coronavirus disease 2019 infection and to investigate the effect of these levels on the prognosis of the disease.

Design: The study was planned prospectively and observationally.

Setting: The study was conducted in a tertiary university hospital.

Patients: Coronavirus disease 2019 patients older than 18 years old, polymerase chain reaction test positive, with signs of pneumonia on tomography, and hospitalized were included in the study. ICU need, development of acute respiratory distress syndrome, and in-hospital mortality were considered as primary endpoints.

Interventions: Blood samples were taken from patients three times for angiotensin II levels.

Measurements And Main Results: Angiotensin II levels were studied by enzyme-linked immunosorbent assay method. The SPSS 24.0 program (Statistics Program for Social Scientists, SPSS, Chicago, IL) was used to analyze the data. A total of 112 patients were included in the study, of which 63.4% of the patients were men. The serum angiotensin II levels were statistically significantly lower in the patients with coronavirus disease 2019 compared with the healthy control group (p < 0.001). There was no statistical significance between the serum angiotensin II levels measured at three different times (p > 0.05). The serum angiotensin II levels of the patients with acute respiratory distress syndrome were found to be statistically significantly lower than those without acute respiratory distress syndrome in three samples collected at different clinical periods (p < 0.05). The angiotensin II levels of the patients who required admission to the ICU at all three times of blood sample collection were found to be statistically significantly lower than those who did not (p < 0.05). Although the serum angiotensin II levels of the patients who died were low, there was no statistically significant difference in mortality at all three times (p > 0.05).

Conclusions: The serum angiotensin II levels decrease significantly in patients with coronavirus disease 2019, and this decrease is correlated with lung damage.

Chest Computed Tomography Findings of Eight Patients With Covid-19 Diagnosis: Case Series.

Acta Biomed 2021 01 19;91(4):e2020136. Epub 2021 Jan 19.

.

COVID-19 is an infectious disease caused by the virus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and declared a pandemic on March 11, 2020, by the world health organization. In Turkey, the first cases began to appear on March 11, 2020. After the cases in China, the appearance of ground glass with or without consolidation in the posterior and periphery of the bilateral lung is determined as the main finding of COVID-19. In this article, we wanted to share the tomography findings of eight patients who were diagnosed with COVID-19 in our emergency department and who had lung involvement.

Tacrolimus-Induced Vision Loss in a Renal Transplant Patient: Posterior Reversible Encephalopathy Syndrome.

Exp Clin Transplant 2019 May 17. Epub 2019 May 17.

From the Cerrahpasa Medical Faculty, Istanbul University Cerrahpasa, Istanbul, Turkey.

Posterior reversible encephalopathy syndrome is a rare and serious neurologic adverse effect of calcineurin inhibitors. The pathophysiology of this clinical entity is still unclear. Impaired cerebral autoregulation and endothelial dysfunction are thought to be the main pathologic processes. Imaging shows the syndrome to be characterized by vasogenic edema or cytotoxic edema in parietal and occipital areas of the brain. With regard to clinic presentation, headache, diminished visual acuity, cortical blindness, altered consciousness, seizures, and hallucinations can be seen. It is known that the clinical presentation is improved when calcineurin inhibitors are stopped early. Here, we present and evaluate a case of a cortical blindness that developed in a 36-year-old patient who had been using tacrolimus after renal transplant and who returned to health after 1 week of hospitalization.
