Reactivation of cytomegalovirus infection in a post-COVID patient leading to cytomegalovirus pneumonia and colitis

COVID-19 is a severe disease characterized by a multifactorial immunodeficient state in critically ill patients who have had no prior immunodeficiencies. Much of the mortality in COVID has been attributed to an unprecedented high number of secondary coinfections ranging from bacterial pneumonia to opportunistic infections such as invasive aspergillosis and mucormycosis. Case reports reporting reactivation of cytomegalovirus (CMV) infection are scanty. To the best of our knowledge, we describe one of the very few cases of a previously immunocompetent healthy individual who suffered from reactivation of CMV infection and involvement of invasive infection (CMV pneumonia and CMV colitis).

Clinical characteristics of human cytomegalovirus pneumonia in children and the diagnosis value of detecting human cytomegalovirus DNA in bronchoalveolar lavage fluid / 中国小儿急救医学

Objective:To investigate the clinical features, therapy and prognosis of human cytomegalovirus(HCMV)pneumonia in pediatric patients, and to analyze the diagnosis value of detecting HCMV DNA in bronchoalveolar lavage fluid(BALF)by real-time PCR.Methods:The clinical characteristics of 58 pediatric inpatients who were HCMV DNA positive in BALF were retrospectively reviewed.All the patients were from Shengjing Hospital of China Medical University from January 2015 to December 2019.Clinical, radiologic, laboratory and microbiologic data was collected for each patient.The study cohort was divided into HCMV productive infection and latent infection consisting of 22 and 36 patients respectively, based on the HCMV active infection in lung or not.Receiver operating characteristic(ROC)curve was used to assess utility of detecting HCMV DNA in BALF and establish a threshold for diagnosis.Results:(1)Compared with patients in latent infection group, the children in productive infection group had a lower age of onset( P<0.05), a higher proportion of male( P<0.05), and more prolonged hospitalization stay( P<0.05). Pulmonary rales, hypoxemia and higher AST, CK, LDH in serum were easier to detect in productive infection group( P<0.05). Higher HCMV DNA copies in BALF was also detected( P<0.01). Patients in productive infection group had significantly more exposure to additional oxygen treatment or mechanical ventilation and systemic hormone therapy( P<0.05), while with poorer outcomes( P<0.05). (2) ROC curve analysis showed that the AUC for HCMV DNA in BALF in diagnosis of HCMV pneumonia was 0.708 with a threshold of 8.83×10 3 copies/mL, a sensitivity of 77.27%, and a specificity of 58.33%. Conclusion:Those who are diagnosed HCMV pneumonia have a lower age of onset with higher male proportion.These children suffered severer clinical signs.The patients with HCMV DNA copies higher than 8.83×10 3 copies/mL in BALF would be more likely to be diagnosed as HCMV pneumonia.

Guidelines for organ donation and transplantation in China during novel coronavirus pneumonia epidemic / 器官移植

In December 2019, a novel coronavirus pneumonia outbreak in Hubei Province spread rapidly to many provinces and cities. As organ transplantation is in the stage of high-quality development in China, how to carry out organ donation and transplantation in a scientific and orderly manner during the severe epidemic, summarize and analyze the clinical characteristics of COVID-19 on organ transplant recipients, and optimize the prevention, early diagnosis and treatment strategies of COVID-19 to ensure medical safety is essential to the development of organ transplantation and the treatment of the patients with end-stage organ failure as well as the overall situation of the prevention and control of COVID-19 epidemic. Thus, based on the instructions of the National Health Committee, the guidelines are issued by several experts organized by Branch of Organ Transplantation of Chinese Medical Association, providing help to the workers and managers of organ donation and transplantation in China. Approved by the Standing Committee of Branch of Organ Transplantation of Chinese Medical Association, the guidelines adopt the 'expert advice', 'prevention and control strategies' and 'guidance' published in China for reference, and will be revised upon changes of the further understanding of COVID-19 and epidemic control situation.

The experience of extracorporeal membrane oxygenator combined with plasma exchange in treatment of a patient with severe cytomegalovirus pneumonia / 中国中西医结合急救杂志

In recent years, with the development of bone marrow and organ transplantation, cytomegalovirus (CMV) has become a common pathogen threatening patients having undergone organ transplantation. CMV may cause severe pulmonary infection and respiratory failure, leading to the death of patient with CMV pneumonia. CMV infectious pneumonia is characterized by the formation of huge type A eosinophil inclusion bodies in the nucleus and cytoplasm of the infected cells. The susceptible population is often associated with low immune function, and to promote the recovery of autoimmune function is the key point for treatment of CMV pneumonia, and the plasma exchange therapy can reconstruct the autoimmune function and improve the prognosis of patients with CMV pneumonia to a certain extent. Now the experience of 1 patient of severe CMV pneumonia treated by ECMO combined with plasmapheresis is reported.

Human Cytomegalovirus Pneumonia and Pulmonary Aspergillosis in a Patient with Acute Myelogenous Leukemia following Chemotherapy / 감염

Cytomegalovirus (CMV) pneumonia is one of the major causes of morbidity and mortality in immunocompromised patients such as transplant recipients. But CMV pneumonia is unusually reported among adults with leukemia who have not undergone transplantation. Because it is a cause of life-threatening pneumonia in adults with leukemia receiving potent immunosuppressive therapies, CMV has emerged as an important pathogen. We report a case of CMV pneumonia and invasive pulmonary aspergillosis in a patient with acute leukemia who have not undergone transplantation. A 31-year-old man with acute myelogenous leukemia developed high fever on day 9 of second consolidation chemotherapy. Six days later, chest radiography showed patchy consolidation with central cavity on right upper lung. Considering fungal pneumonia, amphoterin B was started, then fever was subsided. Chest CT showed necrotizing pneumonia with cavity formation in posterior segment of right upper lobe. Because of several episodes of hemoptysis, lobectomy was performed. Grossly, the area of focal necrosis with central cavity formation and multiple small interstitial nodules were observed. In the area of interstitial nodules, giant cells with intranuclear inclusion and perinuclear halo were found. In the area of focal necrosis, fungal hyphae with acute branching and septation were found. Ganciclovir and immunoglobulin were administered for CMV pneumonia. On day 62 of the chemotherapy, the patient discharged with improved symptoms. After several weeks, unrelated HLA-matched allogeneic stem cell transplantation was performed. On day 14 of transplantation, the patient died due to septic shock of unknown cause.

Thirty six-year-old man presenting acute respiratory failure / 결핵

We report a case of pneumonia in 36 year-old male patient who presented acute respiratory failure and associated radiologic findings of bilateral ground-glass opacity with focal cystic changes, showing rapidly aggravating course and was diagnosed as concomitant Pneumocystis carinii and Cytomegalovirus pneumonia accompanied by acquired immunodeficiency syndrome through antemortem open lung biopsy.

Fatal Cytomegalovirus Pneumonia in a Immunocompetent Patient / 감염

Serious cytomegalovirus (CMV) infection occurs frequently in immunocompromised patients and is a common cause of death. Although primary infection in immunocompetent hosts is normally subclinical, mononucleosis-like syndrome that is characterized by malaise, protracted fever, mild liver function abnormalities, and lymphocytosis with atypical lymphocytes occurs in -10% of patients. Rarely fulminant infection may develop. In both the United States and the United Kingdom, ganciclovir and foscarnet are recommended for the treatment of serious CMV infections in immunocompromised patients. In contrast, there are no recommendations for treatment of severe CMV disease in immunocompetent patients. We describe a case of 45-year-old woman with CMV pneumonia with a fatal outcome for whom there was no evidence of prior immunodeficiency.
