Project description:Since December 2019, a novel coronavirus that caused viral pneumonia broke out and became global pandemic. Coronavirus disease 2019 (COVID-19) is caused by the SARS-CoV-2 virus. Reports on the clinical manifestations in solid organ transplant (SOT) recipients are rare. We report the clinical features and treatment of a Chinese renal transplant recipient with COVID-19. A 46-year-old Chinese woman, who had a renal transplant in 2006 due to chronic glomerulonephritis, was admitted to Renmin Hospital of Wuhan University for fever, cough, and expectoration for more than 10 days and diarrhea for 3 days. At admission, her body temperature was 38.2 °C and pulse oxygen saturation was 96% under oxygen inhalation. There were decreased breath sounds bilaterally. Laboratory data revealed normal leucocyte count, a normal percentage of neutrophils, a normal percentage of lymphocytes, decreased lymphocyte count, elevated procalcitonin and C-reactive protein (CRP), and increased levels of urea, creatinine, and estimated glomerular filtration rate. COVID-19 was confirmed by nasopharyngeal swab and sputum which were positive for SARS-CoV-2 by real-time reverse transcription PCR (RT-PCR). Chest CT revealed multiple patchy and flake ground-glass shadows in bilateral lung fields, and strip shadows in bilateral lower lobes. Treatment included antiviral (umifenovir, hydroxychloroquine), antibacterial (moxifloxacin), and other support therapies. Her symptoms, laboratory data, and chest CT showed trends of gradual improvement, while nasopharyngeal swabs were always positive for SARS-CoV-2. She was finally discharged from hospital on her 70th day of hospitalization when 2 consecutive nasopharyngeal swabs were negative for SARS-CoV-2. This is a rare report on COVID-19 in a renal transplant recipient, which can help enhance the understanding and treatment of COVID-19 in renal transplant recipients.

Project description:The large outbreak of coronavirus disease 2019 (COVID-19) that started in Wuhan, China has now spread to many countries worldwide. Current epidemiologic knowledge suggests that relatively few cases are seen among children, which limits opportunities to address pediatric specific issues on infection control and the children's contribution to viral spread in the community. Here, we report the first pediatric case of COVID-19 in Korea. The 10-year-old girl was a close contact of her uncle and her mother who were confirmed to have COVID-19. In this report, we present mild clinical course of her pneumonia that did not require antiviral treatment and serial viral test results from multiple specimens. Lastly, we raise concerns on the optimal strategy of self-quarantine and patient care in a negative isolation room for children.

Project description:Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for various hematological, immunological and metabolic diseases, replacing the patient's hematopoietic system with donor-derived healthy hematopoietic stem cells. HSCT can be complicated by early and late events related to impaired immunological recovery such as prolonged hypogammaglobulinemia post-HSCT. We present a 16-year-old female patient with sickle-cell disease who underwent HSCT with stem cells from a human leukocyte antigen (HLA) class-II mismatched family donor. While cellular recovery was good post-HSCT, the patient developed mixed chimerism and suffered from cervical lymphadenopathy, recurrent airway infections and cutaneous SLE. She presented with hypogammaglobulinemia and was started on immunoglobulin substitution therapy and antibiotic prophylaxis. B-cell phenotyping showed that she had increased transitional and naïve mature B cells, reduced memory B cells, and diminished marginal zone/natural effector cells. In-depth immunophenotyping and B-cell receptor repertoire sequencing ruled out an intrinsic B-cell defect by expression of activation-induced cytidine deaminase (AID), presence of somatic hypermutations and differentiation into IgG- and IgA-producing plasma cells in vitro. Immunohistochemistry and flow cytometry of lymph node tissue showed a clear block in terminal B-cell differentiation. Chimerism analysis of sorted lymph node populations showed that exclusively patient-derived B cells populated germinal centers, while only a minor fraction of follicular helper T cells was patient-derived. Because of this discrepancy, we deduced that the HLA class-II disparity between patient and donor impedes facilitation of terminal B-cell differentiation in the lymph node. This case highlights disturbed cognate T-B interactions in the secondary lymphoid organs should be considered when deciphering prolonged hypogammaglobulinemia post-HSCT.

Project description:BackgroundThe BNT162b2 vaccine received emergency use authorization from the U.S. Food and Drug Administration for the prevention of severe coronavirus disease 2019 (COVID-19) infection. We report a case of biopsy and magnetic resonance imaging (MRI)-proven severe myocarditis that developed in a previously healthy individual within days of receiving the first dose of the BNT162b2 COVID-19 vaccine.Case summaryAn 80-year-old female with no significant cardiac history presented with cardiogenic shock and biopsy-proven fulminant myocarditis within 12 days of receiving the BNT162b2 COVID-19 vaccine. She required temporary mechanical circulatory support, inotropic agents, and high-dose steroids for stabilization and management. Ultimately, her cardiac function recovered, and she was discharged in stable condition after 2 weeks of hospitalization. A repeat cardiac MRI 3 months after her initial presentation demonstrated stable biventricular function and continued improvement in myocardial inflammation.DiscussionFulminant myocarditis is a rare complication of vaccination. Clinicians should stay vigilant to recognize this rare, but potentially deadly complication. Due to the high morbidity and mortality associated with COVID-19 infection, the clinical benefits of the BNT162b2 vaccine greatly outweighs the risks of complications.

Project description:Background: Takotsubo cardiomyopathy is triggered by emotional or physical stress. It is defined as a reversible myocardial dysfunction, usually with apical ballooning aspect due to apical akinesia associated with hyperkinetic basal left ventricular contraction. Described in cases of viral infections such as influenza, only few have been reported associated with novel coronavirus disease 2019 (COVID-19) in the recent pandemic. Case summary: A 79-years-old man, with cardiovascular risk factors (type 2 diabetes and hypertension) and chronic kidney disease, presented to the emergency room for severe dyspnea after 8 days of presenting respiratory symptoms and fever. Baseline electrocardiogram (ECG) was normal, but he presented marked inflammatory syndrome. He was transferred to an intensive care unit to receive mechanical ventilation within 6 h, due to acute respiratory distress syndrome. He presented circulatory failure 2 days after, requiring norepinephrine support (up to up to 1.04 μg/kg/min). Troponin T was elevated (637 ng/l). ECG showed diffuse T wave inversion. Echocardiography showed reduced left ventricular ejection fraction (LVEF 40%), with visual signs of Takotsubo cardiomyopathy. Cardiac failure resolved after 24 h with troponin T decrease (433 ng/l) and restoration of cardiac function (LVEF 60% with regression of Takotsubo features). Patient died after 15 days of ICU admission, due to septic shock from ventilator-acquired pneumonia. Cardiac function was then normal. Conclusion: Mechanisms of Takotsubo cardiomyopathy in viral infections include catecholamine-induced myocardial toxicity and inflammation related to sepsis. Differential diagnoses include myocarditis and myocardial infarction. Evidence of the benefit of immunomodulatory drugs and dexamethasone are growing to support this hypothesis in COVID-19.

Project description:BackgroundSince coronavirus disease 2019 (COVID-19) was first identified in Wuhan, China, in December 2019, the number of cases has risen exponentially. Clinical characteristics and outcomes among patients with orthotopic heart transplant (OHT) with COVID-19 remain poorly described.MethodsWe performed a retrospective case series of patients with OHT with COVID-19 admitted to 1 of 2 hospitals in Southeastern Michigan between March 21 and April 22, 2020. Clinical data were obtained through review of the electronic medical record. Final date of follow-up was May 7, 2020. Demographic, clinical, laboratory, radiologic, treatment, and mortality data were collected and analyzed.ResultsWe identified 13 patients with OHT admitted with COVID-19. The mean age of patients was 61 ± 12 years, 100% were black males, and symptoms began 6 ± 4 days before admission. The most common symptoms included subjective fever (92%), shortness of breath (85%), and cough (77%). Six patients (46%) required admission to the intensive care unit. Two patients (15%) died during hospitalization.ConclusionsBlack men may be at increased risk for COVID-19 among patients with OHT. Presenting signs and symptoms in this cohort are similar to those in the general population. Elevated inflammatory markers on presentation appear to be associated with more severe illness.

Project description:Farber disease (FD) is an inherited autosomal recessive disorder of lipid metabolism. The hallmark of the disease is systemic accumulation of ceramide due to lysosomal acid ceramidase deficiency. The involvement of the central nervous system is critical in this disorder leading to rapid deterioration and death within a few years after birth. Efforts to treat patients by hematopoietic stem cell transplant (HSCT) have resulted in favorable results in the absence of neurological manifestations. We report the outcomes of HSCT in two patients with FD who received early HSCT and had neurological deterioration posttransplant. We also present a new understanding of the limitations of HSCT in FD management based on our observations of the clinical course of the two patients after therapy.

Project description:Hematopoietic stem cell transplantation (HSCT) is widely used in pediatric patients as a successful curative therapy for life-threatening conditions. The treatment is intensive, with risks of serious complications and lethal outcomes. This study aimed to provide insight into current data on the place and cause of death of transplanted children, the available specialized pediatric palliative care services (SPPCS), and what services HSCT professionals feel the SPPCS team should provide. First, a retrospective database analysis on the place and cause of death of transplanted pediatric HSCT patients was performed. Second, a survey was performed addressing the availability of and views on SPPCS among HSCT professionals. Database analysis included 233 patients of whom the majority died in-hospital: 38% in the pediatric intensive care unit, 20% in HSCT units, 17% in other hospitals, and 14% at home or in a hospice (11% unknown). For the survey, 98 HSCT professionals from 54 centers participated. Nearly all professionals indicated that HSCT patients should have access to SPPCS, especially for pain management, but less than half routinely referred to this service at an early stage. We, therefore, advise HSCT teams to integrate advance care planning for pediatric HSCT patients actively, ideally from diagnosis, to ensure timely SPPCS involvement and maximize end-of-life preparation.

Project description:To identify factors associated with parent activation in parents of children undergoing pediatric hematopoietic stem cell transplant (HSCT) in the 6 months following HSCT, and to address if their association with parent activation changes over time.Measures for this analysis, including the Parent-Patient Activation Measure (Parent-PAM), were completed by parents (N?=?198) prior to their child's HSCT preparative regimen and again at 6 months post-HSCT. Clinical data were also collected. A repeated measures model was built to estimate the association between clinical and demographic factors and parent well-being on Parent-PAM scores. Interactions with time were considered to test for changing effects over time.Throughout the HSCT course, older parent age was associated with lower Parent-PAM scores (??=?-0.29, p?=?0.02) and never being married was associated with higher scores (versus married, ??=?12.27, p?=?0.03). While higher parent emotional functioning scores were not associated with activation at baseline, they were important at 6 months (baseline, ??=?-0.002, p?=?0.96; interaction, ??=?0.14, p?=?0.03). At baseline, longer duration of illness was associated with increased activation, but this effect diminished with time (baseline, ??=?3.29, p?=?0.0002; interaction, ??=?-2.40, p?=?0.02). Activation levels dropped for parents of children who went from private to public insurance (baseline, ??=?2.95, p?=?0.53; interaction, ??=?-13.82, p?=?0.004). Clinical events did not affect Parent-PAM scores.Our findings reveal important changes in the factors associated with parent activation in the first 6 months after pediatric HSCT. These findings may reflect the emotional and financial toll of pediatric HSCT on parent activation.
