Concurrence of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura: a case report and review of the literature.

BACKGROUND: Immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura are both causes of thrombocytopenia. Recognizing thrombotic thrombocytopenic purpura is crucial for subsequent treatment and prognosis. In clinical practice, corticosteroids and rituximab can be used to treat both immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura; plasma exchange therapy is the first-line treatment in thrombotic thrombocytopenic purpura, while corticosteroids are strongly recommended as first-line treatment in immune thrombocytopenic purpura. The differential diagnosis of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura is essential in clinical practice. However, case reports have suggested that immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura can occur concurrently. CASE PRESENTATION: We report the case of a 32-year-old Asian female without previous disease who presented with pancytopenia, concurrent with immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura. The morphology of the megakaryocytes in the bone marrow indicated immune-mediated thrombocytopenia. The patient received glucocorticoid treatment, and her platelet count increased; however, schistocytes remained high during the course of the therapy. Further investigations revealed ADAMTS13 activity deficiency and positive ADAMTS13 antibodies. The high titer of antinuclear antibody and positive anti-U1-ribonucleoprotein/Smith antibody indicated a potential autoimmune disease. However, the patient did not fulfill the current criteria for systemic lupus erythematosus or mixed connective tissue disease. The patient responded well to plasma exchange therapy, and her platelet count remained normal on further follow-up. CONCLUSIONS: Concurrence of immune thrombocytopenic purpura and thrombotic thrombocytopenic purpura is rare, but clinicians should be aware of this entity to ensure prompt medical intervention. Most of the reported cases involve young women. Human immunodeficiency virus infection, pregnancy, and autoimmune disease are the most common underlying conditions.

Elevated levels of fructosamine are independently associated with SARS-CoV-2 reinfection: A 12-mo follow-up study.

BACKGROUND: The association between blood levels of fructosamine (FMN) and recurrent coronavirus disease 2019 (COVID-19) is currently unclear. AIM: To investigate a prospective relationship between blood levels of FMN and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection. METHODS: A total of 146 Chinese hospitalized patients infected with SARS-CoV-2 were consecutively collectively recruited and followed from January 2020 to May 2021. Diagnosis of COVID-19 and SARS-CoV-2 reinfection was based on the diagnostic criteria and treatment protocol in China. The levels of FMN were determined in blood and divided into tertiles based on their distribution in the cohort of COVID-19 patients. Multivariate-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated for SARS-CoV-2 reinfection across the tertiles of FMN levels. A Cox regression model was used to generate the HR for SARS-CoV-2 reinfection in the participants in the top tertile of FMN levels compared with those at the bottom. Disease-free survival was used as the time variable, and relapse was used as the state variable, adjusted for age, gender, influencing factors such as diabetes mellitus, hypertension, and corticosteroid therapy, and clinical indexes such as acute liver failure, acute kidney failure, white blood cell (WBC) count, C-reactive protein, prognostic nutritional index (PNI), and blood lipids. Kaplan-Meier analysis with log-rank tests was used to compare the survival rate between patients with elevated FMN levels (FMN > 1.93 mmol/L, the top tertile) and those with nonelevated levels. RESULTS: Clinical data for the 146 patients with confirmed COVID-19 [age 49 (39-55) years; 49% males] were analyzed. Eleven patients had SARS-CoV-2 reinfection. The SARS-CoV-2 reinfection rate in patients with elevated FMN levels was significantly higher than that in patients with nonelevated FMN (17% vs 3%; P = 0.008) at the end of the 12-mo follow-up. After adjustments for gender, age, diabetes mellitus, hypertension, corticosteroid therapy, WBC count, PNI, indexes of liver and renal function, and blood lipids, patients with nonelevated FMN levels had a lower risk of SARS-CoV-2 reinfection than those with elevated FMN levels (HR = 6.249, 95%CI: 1.377-28.351; P = 0.018). Kaplan-Meier analysis showed that the cumulative survival rate of patients infected with SARS-CoV-2 was higher in patients with nonelevated FMN levels than in those with elevated FMN levels (97% vs 83%; log rank P = 0.002). CONCLUSION: Elevated levels of FMN are independently associated with SARS-CoV-2 reinfection, which highlights that patients with elevated FMN should be cautiously monitored after hospital discharge.

Clinical activity changes in the neurology department of Wenzhou during the COVID-19 pandemic: an observational analysis.

OBJECTIVE: To explore the activity changes in neurology clinical practice that have occurred in tertiary public hospitals during the COVID-19 pandemic. METHODS: Outpatient and inpatient data from the neurology department were extracted from the electronic medical record system of three tertiary Grade A hospitals in Wenzhou. Data were analyzed across 5 months following the beginning of the pandemic (from January 13 to May 17) and compared with the same period in 2019. Data on reperfusion therapy for acute infarction stroke were extracted monthly from January to April. RESULTS: The number of outpatients declined from 102,300 in 2019 to 75,154 in 2020 (26.54%), while the number of inpatients in the three tertiary Grade A hospitals decreased from 4641 to 3437 (25.94%). The latter trend showed a significant drop from the 3rd week to the 7th week. The number of patients in these hospitals decreased significantly, and a significant drop was seen in the neurology department. As usual, stroke was the most common disease observed; however, anxiety/depression and insomnia increased dramatically in the outpatient consultation department. CONCLUSIONS: The results of our study revealed the effects of the COVID-19 pandemic in the clinical practice of neurology in Wenzhou during the outbreak. Understanding the pandemic's trends and impact on neurological patients and health systems will allow for better preparation of neurologists in the future.

Optimization of the Working Procedure of Radionuclide Treatment Ward during 2019-nCoV Prevention

Since the end of 2019, Novel Coronavirus Pneumonia (2019-nCov) has appeared and spread rapidly in the world. During the epidemic period, how to control the infection in the working procedure of radionuclide treatment ward is a clinical protection problem that must be solved. If a novel coronavirus pneumonia (NCP) is suspected or diagnosed, the most important thing is to isolate the relevant doctors and patients on the spot in time and initiate relevant NCP clinical emergency plans and procedures. When the radioactive infected medical waste is disinfected, it should be treated as radioactive waste. Therefore, it is necessary to optimize the working procedures of radionuclide therapy ward.
