COVID-19 in Liver Transplant Patients: A University Hospital Experience.

BACKGROUND: We aimed to examine the comorbidity, disease progress, and vaccination status of liver transplant patients followed up in our hospital who had COVID-19. METHODS: Liver transplant patients with COVID-19 were included between 11 March 2020 and 15 September 2022. Demographic data, disease progress, and COVID-19 vaccines were recorded. The SPSS 24.0 (IBM SPSS, Inc, Armonk, NY, United States) program was used for analysis. The data were analyzed using the χ2 test. P values < .05 were considered clinically significant. RESULTS: Sixteen SARS-CoV-2 polymerase chain reaction (+) patients were detected. Twelve (75.0%) patients were male; the mean age was 49.56 ± 14.0 years (24-76 years). The mean transplant time was 156.69 ± 54.05 months. Four (25.0%) of the 5 (31.3%) patients with comorbidities had hypertension, and 1 (6.3%) had diabetes. None of the patients had an underlying lung disease. All the patients received immunosuppressive therapy, and the most common combination was antimetabolite and calcineurin inhibitor (9 patients [69.2%]). Nine patients (56.3%) had a fever, whereas 6 (37.5%) had respiratory symptoms. Two (33.3%) had pneumonia. Five (31.4%) patients were hospitalized, and 1 (20%) was admitted to the intensive care unit due to non-invasive mechanical ventilation needs. No patient died due to COVID-19. A statistically significant correlation was found between the presence of fever, respiratory symptoms, and hospitalization (P < .05). Of those vaccinated, 10 (66.7%) were infected before the COVID-19 vaccination. CONCLUSIONS: The course of COVID-19 in liver recipients without any underlying disease other than transplantation is not different from that in the healthy population. Immunosuppressive therapy was continued in patients with the disease, and two-thirds did not require hospitalization.

COVID-19 IN LIVER TRANSPLANT PATIENTS: A UNIVERSITY HOSPITAL EXPERIENCE

Aim: We aimed to examine the comorbidity, disease progress and vaccination status of the liver transplant patients followed up in our hospital who had COVID-19. Method: Liver transplant patients with COVID-19 were included between 11 March 2020 and 15 September 2022. Demographic data, disease progress and COVID-19 vaccines were recorded. SPSS24.0 program was used for analysis. The data were analyzed with the chi-square test. P values ​​<0.05 were considered clinically significant. Results: SARS-CoV-2 PCR(+) 16 patients were detected. Twelve (75.0%) patients were male, and the mean age was 49.56 ± 14.0 (24-76). The mean transplant time was 156.69 ± 54.05 months. Four (25.0%) of the five (31.3%) patients with comorbidities had hypertension and one (6.3%) had diabetes. None of the patients had an underlying lung disease. All the patients received immunosuppressive therapy, and the most common combination was the antimetabolite and calcineurin inhibitor group [9 patients (69.2%)]. Nine patients (56.3%) had fever, while six (37.5%) had respiratory symptoms. Two (33.3%) of them had pneumonia. Five (31.4%) patients were hospitalized, and one (20%) was admitted to ICU due to non-invasive mechanical ventilation needs. No patient died due to COVID-19. A statistically significant correlation was found between the presence of fever, respiratory symptoms and hospitalization(p<0.05). Of those vaccinated, 10 (66.7%) were infected before COVID-19 vaccination. Conclusion: The course of COVID-19 in liver recipients without any underlying disease other than transplantation is not different from the healthy population. Immunosuppressive therapy continued in patients with the disease, and two-thirds did not require hospitalization.

The presence of symptoms within 6 months after COVID-19: a single-center longitudinal study.

BACKGROUND: Characterizing the post-COVID health conditions is helpful to direct patients to appropriate healthcare. AIMS: To describe the presence of symptoms in COVID-19 patients within 6 months after diagnosis and to investigate the associated factors in terms of reporting symptoms. METHODS: Data of DEU-COVIMER (a telephone interview-based COVID-19 follow-up center established in a tertiary care hospital) was analyzed for SARS-CoV-2 RNA positive participants aged ≥ 18 years from November 1st, 2020, to May 31st, 2021. Symptom frequencies were stratified by demographic and clinical characteristics at one, three, and 6 months after diagnosis. With the patients who had symptoms at baseline, generalized estimating equations were applied to identify the factors associated with reporting of symptoms. RESULTS: A total of 5610 patients agreed to participate in the study. Symptom frequency was 37.2%, 21.8%, and 18.2% for the first, third, and sixth months. Tiredness/fatigue, muscle or body aches, and dyspnea/difficulty breathing were the most common symptoms in all time frames. In multivariate analysis, older age, female gender (odds ratio OR 1.74, 95% confidence interval 1.57-1.93), bad economic status (OR 1.37, 1.14-1.65), current smoking (OR 1.15, 1.02-1.29), being fully vaccinated before COVID-19 (OR 0.53, 0.40-0.72), having more health conditions (≥ 3 conditions, OR 1.78, 1.33-2.37), having more symptoms (> 5 symptoms, OR 2.47, 2.19-2.78), and hospitalization (intensive care unit, OR 2.18, 1.51-3.14) were associated with reporting of symptoms. CONCLUSIONS: This study identifies risk factors for patients who experience post-COVID-19 symptoms. Healthcare providers should appropriately allocate resources prioritizing the patients who would benefit from post-COVID rehabilitation.

Evaluation of SARS-CoV-2 antibody persistence and viral spread in stool: a long-term care experience before COVID-19 vaccination.

BACKGROUND: Due to elderly residents, nursing homes/assisted living facilities were the most affected places in COVID-19 pandemic. Besides symptomatic patients, asymptomatic patients were detected during routine screening. AIM: This study aims to determine the factors that affect antibody response and viral shedding in stool samples after natural exposure to the virus in residents and staff who recovered from COVID-19 before the vaccine was available. METHODS: This prospective cross-sectional study was conducted at the nation's highest-capacity Residential and Nursing Home. Blood samples were collected between December 15, 2020 and January 15, 2021 from participating residents and staff for anti-SARS-CoV-2 antibody testing. Stool samples were obtained for SARS-CoV-2 PCR testing 2 months after COVID-19. The Social Sciences (SPSS) program version 15.0 was used for statistical analysis. The Mann-Whitney U test compared SARS-CoV-2 antibody concentration between two groups. RESULTS: Four hundred sixty-four (52.3%) residents and 424 (47.7%) staff participated. Entirely 259 (29.2%) participants were anti-SARS-CoV-2 IgG (+) and 255 (28.7%) were SARS-CoV-2 PCR (+). Both antibody and PCR positivity was detected in 196 (76.9%). In PCR (-) group, 63 (10.0%) participants were SARS-CoV-2 IgG (+). Antibody titers were found highest in SARS-CoV-2 PCR (+) male residents. SARS-CoV-2 IgG titers were significantly high in SARS-CoV-2 PCR (+) and hospitalized participants regardless of age. Stool samples were obtained from 61(23.9%) participants and were found negative. CONCLUSION: A durable SARS-CoV-2 IgG antibody response was monitored at least 9 months after the participants were diagnosed with COVID-19. SARS-CoV-2 antibody positivity was detected 76.9% in PCR (+) and 10.0% in PCR (-) participants. Knowing the duration of detectable antibodies is an important finding for developing disease prevention and public health strategies.

The association of antiviral drugs with COVID-19 morbidity: The retrospective analysis of a nationwide COVID-19 cohort.

Background and objectives: Although several repurposed antiviral drugs have been used for the treatment of COVID-19, only a few such as remdesivir and molnupiravir have shown promising effects. The objectives of our study were to investigate the association of repurposed antiviral drugs with COVID-19 morbidity. Methods: Patients admitted to 26 different hospitals located in 16 different provinces between March 11-July 18, 2020, were enrolled. Case definition was based on WHO criteria. Patients were managed according to the guidelines by Scientific Board of Ministry of Health of Turkey. Primary outcomes were length of hospitalization, intensive care unit (ICU) requirement, and intubation. Results: We retrospectively evaluated 1,472 COVID-19 adult patients; 57.1% were men (mean age = 51.9 ± 17.7years). A total of 210 (14.3%) had severe pneumonia, 115 (7.8%) were admitted to ICUs, and 69 (4.7%) were intubated during hospitalization. The median (interquartile range) of duration of hospitalization, including ICU admission, was 7 (5-12) days. Favipiravir (n = 328), lopinavir/ritonavir (n = 55), and oseltamivir (n = 761) were administered as antiviral agents, and hydroxychloroquine (HCQ, n = 1,382) and azithromycin (n = 738) were used for their immunomodulatory activity. Lopinavir/ritonavir (ß [95% CI]: 4.71 [2.31-7.11]; p = 0.001), favipiravir (ß [95% CI]: 3.55 [2.56-4.55]; p = 0.001) and HCQ (ß [95% CI]: 0.84 [0.02-1.67]; p = 0.046) were associated with increased risk of lengthy hospital stays. Furthermore, favipiravir was associated with increased risks of ICU admission (OR [95% CI]: 3.02 [1.70-5.35]; p = 0.001) and invasive mechanical ventilation requirement (OR [95% CI]: 2.94 [1.28-6.75]; p = 0.011). Conclusion: Our findings demonstrated that antiviral drugs including lopinavir, ritonavir, and favipiravir were associated with negative clinical outcomes such as increased risks for lengthy hospital stay, ICU admission, and invasive mechanical ventilation requirement. Therefore, repurposing such agents without proven clinical evidence might not be the best approach for COVID-19 treatment.

Prevalence of Gastrointestinal Symptoms and Clinical Outcomes in Hospitalized Coronavirus Disease 2019 Patients: A Single-Center Study from Turkey.

BACKGROUND: In patients with coronavirus disease 2019, the gastrointestinal symptoms have been reported increasingly in addition to the respiratory system symptoms. The studies show that the prevalence of gastrointestinal system symptoms and how the gastrointestinal system contributes to the severity and prognosis of the disease is still not clear. This study aims to find the prevalence of gastrointestinal symptoms and the correlation between the gastrointestinal symptoms and the clinical results in hospitalized patients diagnosed with coronavirus disease 2019. METHODS: This study retrospectively analyzes patients diagnosed with coronavirus disease 2019 and hospitalized in the pandemic unit between March 2020 and August 2020 and compares their demographic and clinical characteristics, laboratory and radiologic findings, coronavirus disease 2019 treatments received, the clinical course of the disease, and the gastrointestinal symptoms. RESULTS: In our study, we included 322 patients diagnosed with coronavirus disease 2019 and hospitalized; 39 patients (12.1%) were admitted to the hospital with at least one gastrointestinal symptom (nausea and vomiting, diarrhea, abdominal pain, and the loss of taste). Nausea and vomiting are the most common gastrointestinal symptoms with a prevalence of 7.1%, followed by diarrhea with 2.8%, the loss of taste with 2.2%, and abdominal pain with 1.5%. The mean age and D-dimer levels of the patients showing gastrointestinal symptoms were lower than those who did not have any gastrointestinal symptoms. We did not find a significant correlation between the presence of the gastrointestinal symptoms and the severity of the disease, treatment received, risk of acute respiratory distress syndrome and septic shock, admission to the intensive care unit, the need for mechanical ventilation, the mortality rate or the length of hospitalization in the medical floor or the intensive care unit. CONCLUSION: In this study, we observed that 12.1% of coronavirus disease 2019 patients apply to the hospital due to gastrointestinal symptoms. Furthermore, the gastrointestinal symptoms do not seem to affect the severity and the course of the disease, it is important to identify coronavirus disease 2019 patients showing unusual symptoms such as the gastrointestinal symptoms at an early stage to protect healthcare professionals from infection risk.

Fungal colonization and infections in patients with COVID-19 in intensive care units: A real-life experience at a tertiary-care hospital.

PURPOSE: To evaluate the management of patients with COVID-19 in the intensive care units (ICUs) with fungal infection/colonization and to highlight diagnostic problems in these patients. METHODS: We included all patients with a COVID-19 diagnosis who were aged ≥18 years and followed in the ICU for the first 8 months. Patient data were obtained from medical records. We compared the risk factors, laboratory data, and outcomes of patients with fungal infection/colonization. RESULTS: A total of 118 patients (81 men and 37 women) were included. The mean age was 70.3 ± 14.8 (35-94) years. Of the patients, 79 (66.9%) patients were ≥65 years old. Fungal infection/colonization was detected in 39 (33.1%) patients. Fungi were isolated from 34 (28.8%) patients. Ten fungal species were isolated from 51 samples (the most common being Candida albicans). Three patients (2.5%) had proven candidemia. We observed two (1.7%) possible cases of COVID-19-associated pulmonary aspergillosis (CAPA). Eighteen patients (15.3%) underwent antifungal therapy. The risk of fungal infection/colonization increased as the duration of invasive mechanical ventilation increased. The fatality rate was 61.9% and increased with age and the use of mechanical ventilation. The fatality rate was 4.2-times-higher and the use of mechanical ventilation was 35.9-times-higher in the patients aged ≥65 years than in the patients aged <65 years. No relationship was found between fungal colonization/infection, antifungal treatment, and the fatality rate. CONCLUSION: During the pandemic, approximately one-third of the patients in ICUs exhibited fungal infection/colonization. Candida albicans was the most common species of fungal infection as in the pre-pandemic area. Because of the cross-contamination risk, we did not performed diagnostic bronchoscopy and control thorax computed tomography during the ICU stay, and our patients mainly received empirical antifungal therapy.

COVID-19 Pandemic Action Plan of a University Hospital.

In December 2019, in Wuhan, China, scientists observed a sudden and sharp increase in the number of cases of pneumonia and acute respiratory distress syndrome of an unknown origin. By the end of January 2020, the outbreak had spread to Asia, Europe, America, and Australia. In this article, we have outlined the pandemic action plan of our university hospital.

The predictors of COVID-19 mortality in a nationwide cohort of Turkish patients.

The COVID-19-related death rate varies between countries and is affected by various risk factors. This multicenter registry study was designed to evaluate the mortality rate and the related risk factors in Turkey. We retrospectively evaluated 1500 adults with COVID-19 from 26 centers who were hospitalized between March 11 and July 31, 2020. In the study group, 1041 and 459 cases were diagnosed as definite and highly probable cases, respectively. There were 993 PCR-positive cases (66.2%). Among all cases, 1144 (76.3%) were diagnosed with non-severe pneumonia, whereas 212 (14.1%) had severe pneumonia. Death occurred in 67 patients, corresponding to a mortality rate of 4.5% (95% CI:3.5-5.6). The univariate analysis demonstrated that various factors, including male sex, age ≥65 years and the presence of dyspnea or confusion, malignity, chronic obstructive lung disease, interstitial lung disease, immunosuppressive conditions, severe pneumonia, multiorgan dysfunction, and sepsis, were positively associated with mortality. Favipiravir, hydroxychloroquine and azithromycin were not associated with survival. Following multivariate analysis, male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were found to be independent risk factors for mortality. Among the biomarkers, procalcitonin levels on the 3rd-5th days of admission showed the strongest associations with mortality (OR: 6.18; 1.6-23.93). This study demonstrated that the mortality rate in hospitalized patients in the early phase of the COVID-19 pandemic was a serious threat and that those patients with male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were at increased risk of mortality; therefore, such patients should be closely monitored.

Daily inpatient ertapenem therapy can be an alternative to hospitalization for the treatment of complicated urinary tract infections during the COVID-19 pandemic.

BACKGROUND: Physicians hospitalize the patients with complicated urinary tract infections (cUTIs) when they need intravenous antibiotics and outpatient parenteral antimicrobial therapy (OPAT) is unavailable. Daily inpatient antimicrobial therapy is an alternative to hospitalization, which is similar to OPAT; patients go home after they are administered antibiotics in a separate room in the hospital setting. OBJECTIVES: We assessed our previous daily inpatient practice to revitalize the model in the COVID-19 era. MATERIALS AND METHODS: We retrospectively evaluated the clinical and microbiological responses and the cost effectiveness of the patients with cUTIs who received daily inpatient ertapenem therapy. RESULTS: Our study population was 136 patients in 156 episodes. It was a difficult-to-treat group with older age (mean 63.0 ± 14.8 years) and a high burden of underlying conditions (86.5%). The most common causative organisms were Escherichia coli (74.4%) and Klebsiella pneumoniae (19.2%); 89.7% of the isolates were producing extended-spectrum beta lactamase (ESBL). The microbiologic and clinical success rates were 82.1% and 95.5%, respectively. The patients required hospitalization in 16 episodes (10.2%) because of clinical failures (3.8%), superinfections (2%), planned invasive interventions (3.2%), and side effects (1.2%). Our university hospital saved 1608 bed-days and 2596 € (9702 TL) bed costs. CONCLUSIONS: In the COVID-19 pandemic period, this seems to be an effective, safe, and cost-effective way to decrease hospitalizations for cUTIs in settings where OPAT is unavailable.
