COVID-19 in Recent Lung Transplant Recipients: Clinical Outcomes and Management Strategies

BackgroundCOVID-19 causes a wide range of symptoms, with particularly high risk of severe respiratory failure and death in patients with predisposing risk factors such as advanced age or obesity. Recipients of solid organ transplants, and in particular lung transplantation, are more susceptible to viral infection owing to immune suppressive medication. As little is known about the SARS-CoV-2 infection in these patients, this study was undertaken to describe outcomes and potential management strategies in early COVID-19 infection early after lung transplantation.MethodsWe describe the incidence and outcome of COVID-19 in a cohort of recent lung transplant recipients in Munich. Six of 186 patients who underwent lung transplantation in the period between March 2019 and March 2021 developed COVID-19 within the first year after transplantation. We documented the clinical course and laboratory changes for all patients showing differences in the severity of the infection with COVID-19 and their outcomes.ResultsThree of 6 SARS-CoV-2 infections were hospital-acquired and the patients were still in inpatient treatment after lung transplantation. All patients suffered from symptoms. One patient did not receive antiviral therapy. Remdesivir was prescribed in 4 patients and the remaining patient received remdesivir, bamlanivimab and convalescent plasma.ConclusionsCOVID-19 does not appear to cause milder disease in lung transplant recipients compared with the general population. Immunosuppression is potentially responsible for the delayed formation of antibodies and their premature loss. Several comorbidities and a general poor preoperative condition showed an extended hospital stay.     

Rare and Unusual Follow-up Sequelae of Coronavirus Disease 2019: Splenic Mucormycosis in a Renal Transplant Recipient

BackgroundCoronavirus disease 2019 (COVID-19) is associated with adverse outcomes in transplantation communities. Mucormycosis, although a rare infection, has been classically linked to organ transplantation and is associated with exceptionally high morbidity and mortality rates. In this pandemic era, the double infection of mucormycosis and COVID-19 is a lethal combination but is rarely described in the literature on organ transplantation.Case presentationThis article presents the case of a young kidney transplant recipient with diabetes who acquired severe COVID-19, followed by disseminated mucormycosis. The patient was a health care worker who developed severe COVID-19, for which he received remdesivir, anticoagulation, and dexamethasone. No immunomodulatory therapy was used. His maximum oxygen support was bilevel positive airway pressure ventilation. His sugar levels were frequently deranged during the stay. He developed secondary sepsis with Klebsiella, followed by nonhealing lung consolidation. He later developed pleural effusion and splenic abscess, which was detected incidentally. He underwent an emergency splenectomy, the culture of which yielded mucormycosis. Liposomal amphotericin B 5 mg/kg was administered. The patient deteriorated, and a repeat laparotomy yielded gastric perforation, with pus culture showing mucormycosis. The patient died after a long hospital stay.ConclusionsThe diagnosis and management of this dual infection during the pandemic is extremely challenging. In this case, the unusual location of mucormycosis complicating COVID-19 calls for a meticulous approach to opportunistic fungal infections in organ transplant recipients who are positive for COVID-19, especially in those patients with diabetes.     

COVID-19 and Heart Transplant: A Case Series and Review of the Literature

Coronavirus disease 2019 (COVID-19) has resulted in many challenges in patient care, especially among high-risk populations such as heart transplant recipients. Patients with heart transplant experience a significantly higher mortality rate with COVID-19 infection, and management is based on extrapolation from clinical trials done on nontransplant patients and from clinical experience. Here we report 4 cases of patients with heart transplant who presented with COVID-19 infection in late 2020. Patients presented with symptoms similar to those seen in the general population. All 4 patients were admitted to the hospital, and they were all treated with dexamethasone. In addition, 2 patients received remdesivir. Immunosuppressive medications were adjusted to maintain adequate levels of immunosuppression but at the same time allow for an adequate immune response against the infection. All patients were discharged alive from the hospital. We then performed a literature review on studies that included heart transplant patients who developed the infection and developed suggestions for a standardized management approach, which we share in this article.     

Retrospective Evaluation of COVID-19 Infection and COVID-19 Vaccines in Heart Transplant Patients

BackgroundPatients who have performed solid organ transplantation in terms of COVID-19 infection are included in the high-risk group. In this study, it was aimed to evaluate the relationship between vaccination and retrospective evaluation of 32 patients who underwent a heart transplant in the clinic and tested positive for SARS-CoV-2 polymerase chain reaction.MethodsIn this study, demographic characteristics of the cases, comorbidities, timing of heart transplantation, immunosuppressive treatments, symptoms of COVID-19 infection, lung imaging findings, follow-up (outpatient/inpatient), treatments, 1-month mortality, and vaccination histories against COVID-19 infection were evaluated. The data obtained from the study were analyzed with SPSS version 25.0.ResultsThe 3 most common symptoms are cough (37.5%), myalgia (28.1%), and fever (21.8%). COVID-19 infection was severe in 6.2% of the patients, moderate in 37.5%, and mild in 56.2%. Hospitalization was required in 5 patients (15.6%, 1 in the intensive care unit), and the other patients were followed up as an outpatient. Severe COVID-19 infection was seen more in 33% of unvaccinated patients; 93.5% were vaccinated. Nineteen patients (68%) were vaccinated before COVID-19 infection. Our patients received the CoronoVac (Sinovac, China) vaccine.ConclusionCOVID-19 infection is more likely to be severe and mortal in patients with heart transplant recipients. It is also crucial to comply with preventive measures other than immunization in this group of patients. This study is the largest series investigating COVID-19 infection in heart transplant recipient patients in our country.     

Risk Factors for Mortality in Stable Kidney Transplant Patients Infected by SARS-CoV-2 in the South of Spain

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has especially affected kidney transplant (KT) recipients, who are more vulnerable than the general population because of their immunosuppressive status and added comorbidities. The purpose of this study was to determine risk factors related to infection and mortality from COVID-19 in KT recipients.MethodsThe study included 113 stable KT recipients who had polymerase chain reaction–confirmed COVID-19 infection between March 2020 and February 2021, from a total of 2150 KT recipients. Outcomes related to patient survival were analyzed.ResultsThe mean (standard deviation) age of the patients was 56 (14) years; 62% (n = 70) were men. The median time between KT and infection was 88 months (interquartile range, 39-155 months); 90% (n = 102) were on tacrolimus therapy and 81% (n = 92) on mycophenolate mofetil. The clinical presentation was pneumonia (n = 57; 51%), fever (n = 61; 54%), cough (n = 62; 55%), dyspnea (n = 43; 38%), lymphopenia (n = 57; 50%), and gastrointestinal symptoms (n = 28; 25%). A total of 21% (n = 24) required intubation and intensive care unit admission, and 27 patients (25%) were asymptomatic. A total of 9% (n = 10) received hydroxychloroquine therapy plus azithromycin, 11% (n = 12) tocilizumab, 3.7% (n = 4) lopinavir/ritonavir, 49% (n = 55) steroids, 0.9% (n = 1) remdesivir, and 9.3% (n = 11) convalescent plasma. Immunosuppression was reduced in all symptomatic patients. Nineteen patients (17%) died. Cox univariate analysis showed that the factors significantly associated with death were patient age, presence of pneumonia or lymphopenia, and elevated C-reactive protein on admission.ConclusionsMortality in KT recipients with COVID-19 is very high, more than for the general population. Risk factors are patient age, presence of pneumonia or lymphopenia, and a higher C-reactive protein level at the time of diagnosis.     

Coronavirus Disease 2019 Pneumonia in Immunosuppressed Renal Transplant Recipients: A Summary of 10 Confirmed Cases in Wuhan,China

BackgroundPrevious studies on coronavirus disease 2019 (COVID-19) have focused on populations with normal immunity, but lack data on immunocompromised populations.ObjectiveTo evaluate the clinical features and outcomes of COVID-19 pneumonia in kidney transplant recipients.Design, setting, and participantsA total of 10 renal transplant recipients with laboratory-confirmed COVID-19 pneumonia were enrolled in this retrospective study. In addition, 10 of their family members diagnosed with COVID-19 pneumonia were included in the control group.InterventionImmunosuppressant reduction and low-dose methylprednisolone therapy.Outcome measurements and statistical analysisThe clinical outcomes (the severity of pneumonia, recovery rate, time of virus shedding, and length of illness) were compared with the control group by statistical analysis.Results and limitationsThe clinical symptomatic, laboratory, and radiological characteristics of COVID-19 pneumonia in the renal transplant recipients were similar to those of severe COVID-19 pneumonia in the general population. The severity of COVID-19 pneumonia was greater in the transplant recipients than in the control group (five severe/three critical cases vs one severe case). Five patients developed transient renal allograft damage. After a longer time of virus shedding (28.4 ± 9.3 vs 12.2 ± 4.6 d in the control group) and a longer course of illness (35.3 ± 8.3 vs 18.8 ± 10.5 d in the control group), nine of the 10 transplant patients recovered successfully after treatment. One patient developed acute renal graft failure and died of progressive respiratory failure.ConclusionsKidney transplant recipients had more severe COVID-19 pneumonia than the general population, but most of them recovered after a prolonged clinical course and virus shedding. Findings from this small group of cases may have important implications for the treatment of COVID-19 pneumonia in immunosuppressed populations.Patient summaryImmunosuppressed transplant recipients with coronavirus disease 2019 infection had more severe pneumonia, but most of them still achieved a good prognosis after appropriate treatment.     

Effect of Pre-Transplant Covid-19 Exposure on Post-Liver Transplant Clinical Outcomes

BackgroundCOVID-19 has led to an unprecedented global health crisis. This situation caused an immediate reduction in solid organ transplantation activity. This study aimed to present the follow-up results of patients with chronic liver disease who underwent liver transplantation (LT) after a history of COVID-19 infection.MethodsSociodemographic characteristics and clinicopathological data of 474 patients who underwent LT at Inonu University Liver Transplant Institute between March 11, 2020 and March 17, 2022 were prospectively recorded and analyzed retrospectively. Among these, the data of 35 patients with chronic liver disease who were found to be exposed to COVID-19 infection in the pre-LT period were analyzed for this study.ResultsThe median body mass index, Child score, and Model for end-stage liver disease/ Pediatric end-stage liver disease scores of the 35 patients were calculated as 25.1 kg/m² (IQR: 7.4), 9 points (IQR: 4), and 16 points (IQR: 10), respectively. Graft rejection occurred in 4 patients at a median of 25 days post-transplant. Five patients underwent retransplantation at a median of 25 days post-transplant. The most common cause of retransplantation is early hepatic artery thrombosis. There were 5 deaths during postoperative follow-up. Mortality developed in 5 (14.3%) patients exposed to COVID-19 infection in the pretransplant period, whereas mortality occurred in 56 (12.8%) patients not exposed to COVID-19 infection. There was no statistically significant difference in mortality between the groups (P = .79).ConclusionsThe results of this study showed that exposure to COVID-19 before LT does not affect post-transplant patients and graft survival.     

SARS-CoV-2 Infection After Vaccination: Kidney Transplant Recipient Profile and Disease Evolution in a Single Center

BackgroundSARS-CoV-2 infection has had a major impact on kidney transplant patients. Recent evidence suggests that solid organ transplant recipients who received mRNA vaccines reach low immunization rates. There are only few reports about the risk factors and severity of COVID-19 in these patients. Our single center experience describes the patient profile and disease evolution observed in this vulnerable group after inoculation.Material and MethodsRetrospective cohort study with kidney transplant patients who received a COVID-19 vaccine before testing positive for SARS-CoV-19 using polymerase chain reaction. Demographic characteristics and clinical information are described and compared with our previous series of patients who were infected before the initiation of the vaccination rollout.ResultsSixteen kidney transplant recipients diagnosed with COVID-19 after being vaccinated were included and compared with our previous series of 76 unvaccinated patients who were positive for COVID-19. No differences were found among risk factors such as age, time after transplant, hypertension, and obesity between groups (P value > .05). After COVID-19 diagnosis among inoculated patients, 10 patients were hospitalized, and 4 of who met the criteria for admission to the intensive care unit. Three patients died of COVID-19 complications. Despite this, the incidence of infections has decreased after vaccination rollout (P value < .05).ConclusionsPatients’ risk profiles remain constant among recipients who were positive for COVID-19 between waves. We did not find significant differences in hospitalization and severity rates in this reduced group of patients. However, the overall incidence in our kidney transplant population has decreased.     

COVID-19 and solid organ transplantation: Finding the right balance

BackgroundThe COVID-19 pandemic has a great impact on solid organ transplant (SOT) recipients due to their comorbidities and their maintenance immunosuppression. So far, studies about the different aspects of the impact of the pandemic on SOT recipients are limited.ObjectivesThis systematic review summarizes the risk factors that make SOT patients more vulnerable for severe COVID-19 disease or mortality and the impact of immunosuppressive therapy. Furthermore, their clinical outcomes, mortality risk, immunosuppression, immunity and COVID-19 vaccination efficacy are discussed.MethodsA systematic search on PubMed was performed to select original articles on SOT recipients concerning the following four topics: (1) mortality and clinical course; (2) risk factors for mortality and composite outcomes; (3) maintenance immunosuppression; (4) immunity to COVID-19 infection and (5) vaccine immunogenicity. Relevant data were extracted, analyzed and summarized in tables.ResultsThis systematic review includes 77 articles. Mortality was associated with advanced age. Post-transplantation time or comorbidities were variably identified as independent risk factors for mortality or severe disease. However, generally, no comorbidity was reported as a major risk factor. SOT recipients have a higher risk of acute kidney injury, but no higher rate of mortality compared to non-transplanted patients was found. Immunosuppression was individually adjusted, without leading to high rates of graft dysfunction. Generally, no association between type of immunosuppression and mortality was found. SOT patients established humoral and cellular immune responses after COVID-19 disease comparable to immunocompetent people. At last, SOT patients experience a diminished immune response after two-dose vaccination with SARS-COV-2-mRNA-vaccines.ConclusionMore research is needed to address the direct effect of COVID-19 disease on the graft in lung transplant recipients, as well as the factors ameliorating the immune response in SOT recipients.     

Effect of COVID-19 Pandemic on Patients Who Have Undergone Liver Transplantation Because of Hepatocellular Carcinoma

Background and AimMany clinical studies have shown that the COVID-19 case fatality rate is higher in older patients, those with comorbidities, those with immunosuppressive conditions, and those who stay in the intensive care unit. This study aims to evaluate the clinical outcomes of 66 liver transplant (LT) patients with primary liver cancer who were exposed to COVID-19 infection.MethodsDemographic and clinical data of 66 patients with primary liver cancer (hepatocellular carcinoma = 64, hepatoblastoma = 1, cholangiocarcinoma = 1) who underwent LT in our institute and were exposed to COVID-19 infection between March 2020 and November 2021 were analyzed in this cross-sectional study. The following data of the patients were recorded: age, sex, body mass index (kg/m²), blood group, underlying primary liver disease, smoking, tumor characteristics, post-transplant immunosuppressive agents, COVID-19 symptoms, hospitalization, intensive care unit stay, intubation, and other clinical features.ResultsThere were 55 (83.3%) male and 11 (16.7%) female patients, with a median age of 58 years. Sixty-four patients were exposed to COVID-19 only once, whereas the remaining 2 patients were exposed 2 and 4 times, respectively. After exposure to COVID-19, it was determined that 37 patients used antiviral drugs, 25 were hospitalized, 9 were followed in the intensive care unit, and 3 were intubated. One intubated patient was under hospital follow-up because of biliary complications before exposure to COVID-19, and this patient died from sepsis.ConclusionThe low mortality rate of LT patients with primary liver cancer exposed to COVID-19 infection can be attributed to background immunosuppression that prevents cytokine storm. However, it is appropriate to support this study with multicenter studies to make strong comments on this issue.     

Bariatric Surgery is Safe for Patients After Recovery from COVID-19

BackgroundStudies of patients who have undergone surgery while infected with COVID-19 have shown increased risks for adverse outcomes in both pulmonary complications and mortality. It has become clear that the risk of complications from perioperative COVID-19 infection must be weighed against the risk from delayed surgical treatment. Studies have also shown that prior bariatric surgery conveys protection against mortality from COVID-19 and that obesity is the biggest risk factor for mortality from COVID-19 infection in adults under 45 years of age. Studies in patients who have fully recovered from COVID-19 and underwent elective surgery have not become widely available yet.ObjectivesThis multi-institutional case series is presented to highlight patients who developed COVID-19, fully recovered, and subsequently underwent elective bariatric surgery with 30-day outcomes available.SettingNine bariatric surgery centers located across the United States.MethodsThis multicenter case series is a retrospective chart review of patients who developed COVID-19, recovered, and subsequently underwent bariatric surgery. Fifty-three patients are included, and 30-day morbidity and mortality were analyzed.ResultsThirty-day complications included esophageal spasm, dehydration, and ileus. There were no cardiovascular, venous thromboembolism (VTE) or respiratory events reported. There were no 30- day mortalities.ConclusionsBariatric surgery has been safely performed in patients who made a full recovery from COVID-19 without increased complications due to cardiovascular, pulmonary, venous thromboembolism, or increased mortality rates.     

Heart Transplantation from COVID-19–Positive Donors: A Word of Caution

BackgroundDuring the COVID-19 pandemic, efforts to maintain solid-organ transplantation have continued, including the use of SARS-CoV-2–positive heart donors.MethodsWe present our institution's initial experience with SARS-CoV-2–positive heart donors. All donors met our institution's Transplant Center criteria, including a negative bronchoalveolar lavage polymerase chain reaction result. All but 1 patient received postexposure prophylaxis with anti-spike monoclonal antibody therapy, remdesivir, or both.ResultsA total of 6 patients received a heart transplant from a SARS-CoV-2–positive donor. One heart transplant was complicated by catastrophic secondary graft dysfunction requiring venoarterial extracorporeal membrane oxygenation and retransplant. The remaining 5 patients did well postoperatively and were discharged from the hospital. None of the patients had evidence of COVID-19 infection after surgery.ConclusionHeart transplants from SARS-CoV-2 polymerase chain reaction–positive donors are feasible and safe with adequate screening and postexposure prophylaxis.     

Lung Transplant as a Treatment for Patients with End-Stage Respiratory Failure Due to COVID-19

BackgroundCOVID-19 may lead to development of irreversible acute respiratory distress syndrome. Some patients sustain severe respiratory failure after infection subsides. They may require lung transplant as a last resort treatment. The aim of the study is to assess the effect and feasibility of lung transplant as a treatment for patients with severe irreversible respiratory failure due to COVID-19.MethodsThis retrospective study pertains to analysis of 119 patients in critical condition who were referred to Lung Transplant Ward (Zabrze, Poland). between July 2020 and June 2021 after developing respiratory failure requiring extracorporeal membrane oxygenation, invasive ventilation, or both, as well as a few patients on high-flow oxygen therapy. Inclusion criteria for referral were confirmed lack of viral disease and exhaustion of other therapeutic options.ResultsOf the referred patients, 21.84% were disqualified from such treatment owing to existing contraindications. Among the suitable patients, 75.8% died without transplant. Among all patients who were qualified for lung transplant, only 9 patients became double lung transplant recipients. Intraoperative mortality for this procedure was 33%. Four patients were discharged after the procedure and are currently self-reliant with full respiratory capacity.ConclusionsPatients with severe irreversible respiratory failure after COVID-19 present significantly high mortality without lung transplant. This procedure may present satisfactory results but must be performed in a timely fashion owing to critical condition and scarcity of lung donors, only aggravated around the time of peak infection waves.     

COVID-19 Infection in Kidney Transplant Recipients: A Single Center Experience

BackgroundKidney transplant recipients appear to be particularly high risk for critical COVID-19 illness owing to chronic immunosuppression and coexisting conditions. The aim of this study is to present the clinical characteristics and outcomes of our hospital's kidney transplant recipients who were hospitalized due to COVID-19 infection.MethodsIn our retrospective observational study of COVID-19 PCR-positive patients, 31 of them were hospitalized with COVID-19 pneumonia and they were evaluated using demographics, laboratory data, treatment, and outcome. The prognostic nutritional index (PNI), which is calculated using the serum albumin concentration and total lymphocytic count, was also evaluated. The baseline immunosuppressive therapy of patients at the time of admission and the treatments they received during their hospitalization were recorded. All patients were treated with favipiravir.ResultsOf the 31 renal transplant patients with COVID-19 pneumonia, 20 were male and the mean age was 52.7 ± 13.4. Nine (29%) of the patients died. All patients were treated with favipiravir for 5 days; laboratory tests were recorded before and after treatment. The mean PNI of the patients who survived was higher than the patients who died.ConclusionsThe 9 patients who died had lower PNI and higher neutrophil-to-lymphocyte ratio (NLR), creatinine, l-lactate dehydrogenase (LDH), ferritin, and C-reactive protein (CRP) levels. Hospitalized kidney transplant recipients with COVID-19 have higher rates of mortality. The PNI exhibited good predictive performance and may be a useful clinical marker that can be used for estimating survival in COVID-19 patients.     

Case Report of COVID-19 Infection After Kidney Transplant Treated With Casirivimab-Imdevimab and Mycophenolate Mofetil Changed to Everolimus

BackgroundCasirivimab-imdevimab is a cocktail of 2 monoclonal antibodies designed to prevent infection by SARS-CoV-2, the virus that causes COVID-19. Casirivimab-imdevimab has been approved in Japan for treating mild to moderate COVID-19; however, to our knowledge, there are no reports of its use after kidney transplant from a live donor. Everolimus, an antineoplastic chemotherapy drug, is expected to be effective in inhibiting the spread of SARS-CoV-2 and preventing its replication, which may facilitate treatment. Here, we report a case of COVID-19 infection after kidney transplant that was initially treated with casirivimab-imdevimab and mycophenolate mofetil but was later changed to everolimus.Case ReportA 47-year-old man underwent living donor kidney transplant from his mother in 2017. Immunosuppression therapy was underway through the administration of tacrolimus, mycophenolate mofetil, and methylprednisolone. In early September 2021, he was diagnosed as having COVID-19 and was hospitalized on day 3. On hospitalization, mycophenolate mofetil was discontinued and casirivimab-imdevimab and heparin were started. The patient started an everolimus regimen on day 5. The clinical course was successful without rejection. There was no exacerbation of COVID-19; the patient's serum creatinine levels and renal function had otherwise remained stable.ConclusionsWe could safely treat a patient with casirivimab-imdevimab after kidney transplant. It is suggested that casirivimab-imdevimab can prevent COVID-19 from becoming severe and can be administered without worsening renal function. In addition, everolimus may have inhibited the spread of the virus and prevented it from replicating.     

Post-COVID Subacute Thyroiditis and Bronchiolitis in a Lung Transplant Recipient: A Case Report

Lung transplant recipients are at risk for life-threatening infections including severe acute respiratory syndrome coronavirus 2-associated COVID-19. Several viral infections have been associated with the development of chronic lung allograft dysfunction. Long-term outcomes of COVID-19 on graft function are not known.A 53-year-old female patient, who underwent bilateral lung transplantation 3 years before because of stage IV sarcoidosis and secondary pulmonary hypertension was admitted in the second wave of the pandemic because of COVID-19 with symptoms including dry cough. Chest computed tomography showed ground glass opacities affecting 25% to 50% of the lung parenchyma. She was admitted to the COVID-19 Unit of our clinic. She received oxygen via nasal cannula, remdesivir, and low-dose methylprednisolone while mycofenolate acid administration was stopped. Her clinical condition improved. The first follow-up visit 1 month after the infection demonstrated deterioration in lung function. Computed tomography scan showed almost complete resolution; transbronchial biopsy was performed and proved acute allograft rejection. During the hospitalization a new onset atrial fibrillation was confirmed. In the background of atrial fibrillation and simultaneous neck pain, severe hyperthyroidism was proven. Because of thyroiditis and lung allograft rejection, high-dose steroid treatment was initiated and everolimus was added to the immunosuppressive therapy. Donor specific antibodies were also detected, hence plasmapheresis was indicated and continued with photoferesis. On the follow-up spirometry the values were stable; however, they did not reach pre-COVID levels.In lung transplant recipients COVID-19 might trigger allograft rejection in addition to virus-related thyroid disease.     

Kidney Transplantation and COVID-19: Two Case Reports

Immunocompromised populations are at great risk of the current 2020 global emergency of coronavirus disease 2019 (COVID-19), and treatment of kidney transplant recipients with COVID-19 is currently not declared. Hence, the purpose of the study is to set a clear treatment regimen. We report here a therapeutic course of 2 patients who underwent transplant surgery in March 2020 and got infected soon after. Since the transplant, these 2 patients have received triple maintenance immunosuppressive therapy with oral tacrolimus, mycophenolate mofetil (MMF), and prednisone, and they have been regularly followed up at our hospital. The tacrolimus trough level was between 10 and 12 ng/mL. After the diagnosis of COVID-19, MMF was stopped and the tacrolimus dose was reduced so that blood level was between 4 and 6 ng/mL. The first patient was a 30-year-old man who, despite being treated with hydroxychloroquine, favipiravir, oseltamivir, and azithromycin therapy, died because of the presence of other comorbidities. The second case was a 58-year-old man who fully recovered from COVID-19 pneumonia with treatment with methylprednisolone, MMF, azithromycin, favipiravir, hydroxychloroquine, and reduction in immunosuppression dosage. This reflects the importance of using glucocorticoids in the treatment of COVID-19 along with other medications and the decreased mortality rate associated with their use.
