COVID-19 in kidney transplant recipients.

There is minimal information on coronavirus disease 2019 (COVID-19) in immunocompromised individuals. We have studied 10 patients treated at 12 adult care hospitals. Ten kidney transplant recipients tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by polymerase chain reaction, and 9 were admitted. The median age was 57 (interquartile range [IQR] 47-67), 60% were male, 40% Caucasian, and 30% Black/African American. Median time from transplant to COVID-19 testing was 2822 days (IQR 1272-4592). The most common symptom was fever, followed by cough, myalgia, chills, and fatigue. The most common chest X-ray and computed tomography abnormality was multifocal patchy opacities. Three patients had no abnormal findings. Leukopenia was seen in 20% of patients, and allograft function was stable in 50% of patients. Nine patients were on tacrolimus and a mycophenolic antimetabolite, and 70% were on prednisone. Hospitalized patients had their antimetabolite agent stopped. All hospitalized patients received hydroxychloroquine and azithromycin. Three patients died (30%), and 5 (50%) developed acute kidney injury. Kidney transplant recipients infected with COVID-19 should be monitored closely in the setting of lowered immunosuppression. Most individuals required hospitalization and presenting symptoms were similar to those of nontransplant individuals.

A Novel Case Report of Severe Aplastic Anemia with COVID Infection.

Aplastic anemia is a rare disease of the hematopoietic system. Although some viral agents have been implicated, the association between COVID-19 and aplastic anemia is unclear. In this way, several cases of aplastic anemia have been reported following infection with COVID-19. Importantly, we reported a 16-year-old girl with severe aplastic anemia with no history of disease following an Omicron infection who did not respond well to treatment despite supportive treatment and immunosuppression.

Characteristics and Outcomes of Over 300,000 Patients with COVID-19 and History of Cancer in the United States and Spain.

BACKGROUND: We described the demographics, cancer subtypes, comorbidities, and outcomes of patients with a history of cancer and coronavirus disease 2019 (COVID-19). Second, we compared patients hospitalized with COVID-19 to patients diagnosed with COVID-19 and patients hospitalized with influenza. METHODS: We conducted a cohort study using eight routinely collected health care databases from Spain and the United States, standardized to the Observational Medical Outcome Partnership common data model. Three cohorts of patients with a history of cancer were included: (i) diagnosed with COVID-19, (ii) hospitalized with COVID-19, and (iii) hospitalized with influenza in 2017 to 2018. Patients were followed from index date to 30 days or death. We reported demographics, cancer subtypes, comorbidities, and 30-day outcomes. RESULTS: We included 366,050 and 119,597 patients diagnosed and hospitalized with COVID-19, respectively. Prostate and breast cancers were the most frequent cancers (range: 5%-18% and 1%-14% in the diagnosed cohort, respectively). Hematologic malignancies were also frequent, with non-Hodgkin's lymphoma being among the five most common cancer subtypes in the diagnosed cohort. Overall, patients were aged above 65 years and had multiple comorbidities. Occurrence of death ranged from 2% to 14% and from 6% to 26% in the diagnosed and hospitalized COVID-19 cohorts, respectively. Patients hospitalized with influenza (n = 67,743) had a similar distribution of cancer subtypes, sex, age, and comorbidities but lower occurrence of adverse events. CONCLUSIONS: Patients with a history of cancer and COVID-19 had multiple comorbidities and a high occurrence of COVID-19-related events. Hematologic malignancies were frequent. IMPACT: This study provides epidemiologic characteristics that can inform clinical care and etiologic studies.

Very severe immune aplastic anemia after mRNA vaccination against COVID-19 responds well to immunosuppressive therapy: clinical characteristics and comparison to previous reports.

OBJECTIVE: Various hematologic side effects of the Coronavirus Disease 2019 (COVID-19) vaccination has been reported, and most of them are thought to be related to autoimmune pathways. To the best of our knowledge, only few cases of post-COVID-19 vaccination aplastic anemia (AA) have been reported and there is no reported Korean case of COVID-19 vaccine-induced AA yet. We present a case of severe immune-mediated AA that developed after the administration of a messenger ribonucleic acid (mRNA) gene-based spike protein vaccine against COVID-19, which responded well to immunosuppressive therapy, and discuss the probable pathogenesis of AA and the implication of vaccination along with a comparison of previous cases reported. METHODS: A 53-year-old Korean man developed sudden pancytopenia three months after COVID-19 vaccination. To evaluate the cause of pancytopenia, a bone marrow study was performed. RESULTS: A diagnosis of AA was made through the bone marrow study and he received triple immunosuppressive therapy (IST). After triple IST for five months, his blood cell count was improved and maintained without transfusion and his follow-up bone marrow examination showed improved cellularity. CONCLUSION: COVID-19 vaccine might be associated with the development of immune-mediated AA. Prompt hematologic evaluation should be performed when there are symptoms or signs suggestive of cytopenia after COVID-19 vaccination. Although the clinical outcome of post-vaccination AA varies, a good prognosis can be possible for patients with COVID-19 vaccination-induced AA.

Immunosuppression is a Double-Edged Sword in COVID-19 Treatment: a Case Report of Rhino-Orbito-Cerebral Mucormycosis.

BACKGROUND: Mucormycosis is a life-threatening fungal infection mostly occurring in immunosuppressed patients such as organ transplant or diabetic patients. In this paper, we described a case of COVID-19 with rhino-orbito-cerebral mucormycosis. METHODS: The nucleic acid amplification test (NAAT) from a nasopharyngeal sample for SARS-CoV-2 was done. Demographic data, biochemical tests, paranasal sinuses (PNS) CT scan, brain CT scan, chest CT scan, and palate biopsy were performed. RESULTS: The NAAT was positive for SARS-CoV-2. PNS CT scan revealed mucosal thickening of all paranasal sinuses, brain CT scan showed hypodense area in antero-inferior cortex, and chest CT scan revealed diffuse ground glass opacity in favor of COVID-19 infection. Palate biopsy revealed fibroconnective tissue with broad pauciseptated ribbon-like hyphae. CONCLUSIONS: In this paper, a case of COVID-19 with rhino-orbito-cerebral mucormycosis was described. The treatment with immunosuppressive drugs predisposed this patient to secondary fungal infection. Immunosuppression is a double-edged sword in COVID-19 treatment and immunosuppressive drugs should be prescribed only in severely ill patients and for a short period.

Impact of solid organ transplant status on outcomes of hospitalized patients with COVID-19 infection.

BACKGROUND: The COVID-19 pandemic has caused significant morbidity and mortality in solid organ transplant (SOT) recipients. However, it remains unclear whether the risk factor for SOT patients is the immunosuppression inherent to transplantation versus patient comorbidities. METHODS: We reviewed outcomes in a cohort of SOT (n = 129) and non-SOT (NSOT) patients (n = 708) admitted to the University of California, Los Angeles for COVID-19 infection. Data analyses utilized multivariate logistic regression to evaluate the impact of patient demographics, comorbidities, and transplant status on outcomes. SOT patients were analyzed by kidney SOT (KSOT) versus nonkidney SOT (NKSOT) groups. RESULTS: SOT and NSOT patients with COVID-19 infection differed in terms of patient age, ethnicity, and comorbidities. NKSOT patients were the most likely to experience death, with a mortality rate of 16.2% compared with 1.8% for KSOT and 8.3% for NSOT patients (p = .013). Multivariable analysis of hospitalized patients revealed that patient age (odds ratio [OR] 2.79, p = .001) and neurologic condition (OR 2.66, p < .001) were significantly associated with mortality. Analysis of ICU patients revealed a 2.98-fold increased odds of death in NKSOT compared with NSOT patients (p = .013). CONCLUSIONS: This study demonstrates the importance of transplant status in predicting adverse clinical outcomes in patients hospitalized or admitted to the ICU with COVID-19, especially for NKSOT patients. Transplant status and comorbidities, including age, could be used to risk stratify patients with COVID-19. This data suggests that immunosuppression contributes to COVID-19 disease severity and mortality and may have implications for managing immunosuppression, especially for critically ill patients admitted to the ICU.

Clinical insights into the role of immunosuppression in solid organ transplant recipients with COVID-19.

INTRODUCTION: The COVID-19 pandemic has disproportionately affected patients who have undergone solid organ transplantation (SOT). OBJECTIVES: We aimed to assess a cohort of transplant recipients who developed COVID­19, with a focus on immunosuppressive regimen, blood tacrolimus levels, clinical course, and patient and graft outcomes. PATIENTS AND METHODS: During the first 12 months of the pandemic, we identified ambulatory SOT recipients, including kidney, liver, and heart transplant recipients, diagnosed with SARS­CoV­2 infection. Baseline and follow­up data on graft function, immunosuppression, and patient and graft outcomes were assessed. RESULTS: Of the 2091 ambulatory patients, we identified 201 transplant recipients (9.6%) with SARS­CoV­2 infection (kidney transplant, n = 112; heart transplant, n = 56; liver transplant, n = 33). Patients after recent kidney (during 2015-2020) or heart (during 2020) transplant were significantly more often diagnosed with COVID ­19 than patients with a longer time since transplant. Additionally, blood trough tacrolimus levels measured during or shortly after COVID­19 in 23 kidney graft recipients were significantly increased by a median of 76.1% (interquartile range, 47.4%-109.4%) relative to predose trough levels. However, liver function parameters were not elevated, necessitating a tacrolimus dose reduction in 73.9% of the patients. CONCLUSIONS: In our study, kidney transplant recipients showed significant disturbances of tacrolimus metabolism, which may account for kidney function worsening during COVID­19. Moreover, infection was more common in patients with recent kidney or heart transplant, which suggests that the level of immunosuppression may affect morbidity related to SARS­CoV­2 infection.

Antibody Responses after SARS-CoV-2 Vaccination in Patients with Liver Diseases.

The novel mRNA-based vaccines against SARS-CoV-2 display encouraging safety and efficacy profiles. However, there is a paucity of data regarding their immunogenicity and safety in patients with liver diseases (PWLD), especially in those with cirrhosis. We prospectively assessed anti-SARS-CoV-2 S-spike IgG antibodies and neutralizing activity in fully vaccinated PWLD (n = 87) and controls (n = 40). Seroconversion rates were 97.4% (37/38) in cirrhotic PWLD, 87.8% (43/49) in non-cirrhotic PWLD and 100% (40/40) in controls. Adequate neutralizing activity was detected in 92.1% (35/38), 87.8% (43/49) and 100% (40/40) of cirrhotics, non-cirrhotics and controls, respectively. On multivariable analysis, immunosuppressive treatment was negatively correlated with anti-SARS-CoV-2 antibody titers (coefficient (SE): -2.716 (0.634), p < 0.001) and neutralizing activity (coefficient (SE): -24.379 (4.582), p < 0.001), while age was negatively correlated only with neutralizing activity (coefficient (SE): -0.31(0.14), p = 0.028). A total of 52 responder PWLD were reassessed approximately 3 months post-vaccination and no differences were detected in humoral responses between cirrhotic and non-cirrhotic PWLD. No significant side effects were noted post vaccination, while no symptomatic breakthrough infections were reported during a 6-month follow up. Overall, our study shows that m-RNA-based SARS-CoV-2 vaccines are safe and efficacious in PWLD. However, PWLD under immunosuppressive treatment and those of advanced age should probably be more closely monitored after vaccination.

Alcohol use disorder in the COVID-19 era: Position paper of the Italian Society on Alcohol (SIA).

Coronavirus disease 2019 (COVID-19) first emerged in China in November 2019. Most governments have responded to the COVID-19 pandemic by imposing a lockdown. Some evidence suggests that a period of isolation might have led to a spike in alcohol misuse, and in the case of patients with alcohol use disorder (AUD), social isolation can favour lapse and relapse. The aim of our position paper is to provide specialists in the alcohol addiction field, in psychopharmacology, gastroenterology and in internal medicine, with appropriate tools to better manage patients with AUD and COVID-19,considering some important topics: (a) the susceptibility of AUD patients to infection; (b) the pharmacological interaction between medications used to treat AUD and to treat COVID-19; (c) the reorganization of the Centre for Alcohol Addiction Treatment for the management of AUD patients in the COVID-19 era (group activities, telemedicine, outpatients treatment, alcohol-related liver disease and liver transplantation, collecting samples); (d) AUD and SARS-CoV-2 vaccination. Telemedicine/telehealth will undoubtedly be useful/practical tools even though it remains at an elementary level; the contribution of the family and of caregivers in the management of AUD patients will play a significant role; the multidisciplinary intervention involving experts in the treatment of AUD with specialists in the treatment of COVID-19 disease will need implementation. Thus, the COVID-19 pandemic is rapidly leading addiction specialists towards a new governance scenario of AUD, which necessarily needs an in-depth reconsideration, focusing attention on a safe approach in combination with the efficacy of treatment.

COVID-19-associated-mucormycosis: possible role of free iron uptake and immunosuppression.

COVID-19-associated-mucormycosis, commonly referred to as the "Black Fungus," is a rare secondary fungal infection in COVID-19 patients prompted by a group of mucor molds. Association of this rare fungal infection with SARS-CoV-2 infection has been declared as an endemic in India, with minor cases in several other countries around the globe. Although the fungal infection is not contagious like the viral infection, the causative fungal agent is omnipresent. Infection displays an overall mortality rate of around 50%, with many other secondary side effects posing a potential threat in exacerbating COVID-19 mortality rates. In this review, we have accessed the role of free iron availability in COVID-19 patients that might correlate to the pathogenesis of the causative fungal agent. Besides, we have analyzed the negative consequences of using immunosuppressive drugs in encouraging this opportunistic fungal infection.

SARS-CoV-2 infection in heart transplant recipients: a systematic literature review of clinical outcomes and immunosuppression strategies.

The impact of SARS-CoV-2 infection on heart transplant recipients is unknown. Literature is limited to case reports and series. The purpose of this study is to identify the clinical features, outcomes, and immunosuppression strategies of heart transplant recipients with COVID-19 infection. A systematic review was conducted using the search term "Coronavirus" or COVID," "SARS-CoV-2," "cardiac transplantation," and "heart transplant." Case reports and retrospective studies were gathered by searching Medline/PubMed, Google Scholar, CINAHL, Cochrane CENTRAL, and Web of Science. Thirty-three articles were selected for review. We identified 74 cases of SARS-CoV-2 infection in heart transplant and heart-kidney transplant recipients. The mean age was 60.5 ± 15.8 years, and 82.4% were males with median time from transplant of 6.5 years. Commonest symptoms were fever, cough, and dyspnea, but new left ventricular (LV) dysfunction was rare. Leukocytosis, lymphopenia, elevated inflammatory markers, and bilateral ground-glass opacities were common. Mortality was high, with particularly poor survival in patients who required intensive care unit (ICU) admission and older patients. Immunosuppression involved discontinuation of antimetabolites and steroids. COVID-19 infection in heart transplant (HT) recipients presents similarly to the general population, but new onset of LV dysfunction is uncommon. Immunosuppression strategies include increase in corticosteroids and discontinuation of antimetabolites.

Prior immunosuppressive therapy is associated with mortality in COVID-19 patients: A retrospective study of 835 patients.

Though it is widely believed that chronic immunosuppressive medications increase the severity of coronavirus disease 2019 (COVID-19) illness, there is little data to support this. We performed a retrospective study of COVID-19 positive patients diagnosed at a single academic medical center between March 10, 2020 and October 13, 2020. A total of 835 patients diagnosed with COVID-19 by polymerase chain reaction were included (median age 64 years; 52% female). Of these, 46 (5.5%) had a prescription for an immunosuppressive therapy before diagnosis, most commonly oral steroids (20, 43%), mycophenolate (12, 26%), or tacrolimus (11, 24%). Patients on immunosuppressive therapy with COVID-19 had increased mortality (30% vs. 17%, p = 0.036; odds ratio 2.1, 95% confidence interval 1.11-4.04), which remained significant (p = 0.040) after performing multivariate logistic regression controlling for gender, age, race, and comorbidity status. Laboratory markers of inflammation were uniformly elevated in both patients on or not on immunosuppressive therapies who died, but lymphocytes and neutrophils were decreased in both COVID-19 patients on immunosuppressive therapies who died and who remained alive. These findings demonstrate that COVID-19 disease is more severe in patients taking prior immunosuppressive medications. This finding emphasizes the need for aggressive monitoring and supportive care for immunosuppressed patients who are diagnosed with COVID-19.

The effect of immunosuppressive therapy after liver transplantation on activities of daily living and fear of death during the COVID-19 pandemic.

BACKGROUND: In our study, we aimed to investigate the effect of immunosuppressive therapy after liver transplantation on activities of daily living and fear of death during the COVID-19 pandemic. METHODS: This study was conducted as a cross-sectional study with the participation of 213 liver transplant patients hospitalized in the liver transplant center of a university hospital. The data analysis was performed with IBM SPSS (Statistical Package for the Social Sciences) Statistics 25. RESULTS: Katz's Activities of Daily Living (ADL) were semi-independent and the total score was 11.07 ± 1.59, and the Death Attitude Profile-Revised (DAP-R) total score was 152.23 ± 5.34. It was determined that the DAP-R score was around 150 points in the minimum and maximum score ranges of Katz ADL after liver transplantation. CONCLUSIONS: High fear of death threatens resilience and can make patients feel lonely, helpless, sad, abandoned and stressed. Clinicians should spend more time with their patients.

Triple infection with disseminated tuberculosis, invasive aspergillosis and COVID-19 in an organ transplant recipient with iatrogenic immunosuppression.

A 39-year-old man with diabetes mellitus and hypertension presented two years following renal transplantation with evening pyrexia, night sweats and loss of weight. He was diagnosed with disseminated tuberculosis and invasive aspergillosis and commenced on antituberculous and antifungal therapy. Immunosuppressants except for the maintenance dose of steroids were discontinued. Two weeks later, he acquired severe COVID-19 pneumonia complicated with type 1 respiratory failure and haemodynamic instability. He was treated with non-invasive ventilation and inotropic support with a vasopressor-augmenting dose of steroids. Management challenges were diagnosing the respiratory pathologies with limited investigations, deciding on continuation of steroids in an organ transplant recipient with disseminated infection and deciding the ceiling of care in a low-resource setting given the background of multiple pulmonary insults. A multidisciplinary team decided to continue high-dose steroids and escalate to a full ceiling of care. He recovered from COVID-19 pneumonia 15 days following diagnosis and was discharged home. The potential adverse effects of steroids on tuberculosis and aspergillosis are to be monitored during follow-up.

Immunosuppression in solid organ transplant recipients with Covid-19: More data, but still complicated.

"Outcomes of COVID-19 in solid organ transplant (SOT) recipients: a matched cohort study" by Pereira et al found similar 28 day mortality among hospitalized SOT recipients and comorbidity matched controls, shedding light on the relationship between immunosuppression and Covid-19 outcomes.

[Update 2021: COVID-19 from the perspective of gastroenterology]. / Update 2021: COVID-19 aus Sicht der Gastroenterologie.

During COVID 19 pandemic patients typically present with respiratory symptoms. However, in a significant number of patients the gastrointestinal tract is also involved in the disease. Up to 20 % of patients suffering from gastrointestinal symptoms. New insights in pathophysiological aspects might open new therapeutic concepts. This up-date includes current data regarding epidemiology of gastrointestinal symptoms in COVID 19, its role for prognosis and specific risks in relation to immunosuppressive therapies and underlying diseases.

Lupus, vaccinations and COVID-19: What we know now.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the virus causing Coronavirus disease 2019 (COVID-19), has had a huge impact on health services, with a high mortality associated with complications including pneumonia and acute respiratory distress syndrome. Patients with systemic lupus erythematosus (SLE) are at increased risk of viral infections, and recent data suggests they may be at an increased risk of poor outcomes with COVID-19. This may be particularly true for those on rituximab or high dose steroids. A huge international effort from the scientific community has so far resulted in the temporary authorisation of three vaccines which offer protection against SARS-CoV-2, with over 30 other vaccines being evaluated in ongoing trials. Although there has historically been concern that vaccines may trigger disease flares of SLE, there is little convincing evidence to show this. In general lupus patients appear to gain good protection from vaccination, although there may be reduced efficacy in those with high disease activity or those on immunosuppressive therapies, such as rituximab or high dose steroids. Recent concerns have been raised regarding rare clotting events with the AstraZeneca/Oxford vaccine and it is currently unknown whether this risk is higher for those patients with secondary antiphospholipid syndrome. With the possibility of annual COVID vaccination programmes in the future, prospective data collection and registries looking at the effect of vaccination on SLE disease control, the incidence of COVID-19 in SLE patients and severity of COVID-19 disease course would all be useful. As mass vaccination programmes begin to roll out across the world, we assess the evidence of the use of vaccines in SLE patients and in particular vaccines targeting SARS-CoV-2.
