A limited number of cases of thrombotic microangiopathy (TMA) have previously been reported in association with COVID-19. Our report describes two cases of TMA associated with COVID-19, one of which was successfully treated with eculizumab. The first case was a 23-month-old girl, and the second case was a 9-month-old boy. PCR tests for SARS-CoV-2 were positive in both cases, and laboratory results showed microangiopathic haemolytic anaemia, thrombocytopenia, and acute kidney injury. No known aetiology for TMA was found in either case. Stool tests for Shigatoxin-producing Escherichia coli were negative. Coagulation tests, ADAMTS13 activity, serum complement levels, and homocysteine levels were all within the normal range. No known genetic mutation was found, including mutations of complement, diacylglycerol kinase epsilon, and cobalamin C. In the first case, eculizumab was administered due to persistent haemolysis and prolonged anuria. In conclusion, TMA may be associated with COVID-19 infection. Treatment with eculizumab may be beneficial in selected patients because of the potential activation of the complement system. 相似文献

Background and Aims:Trans-arterial chemoembolization (TACE) has become a widely accepted treatment in unresectable hepatocellular carcinoma (HCC). We aimed at comparing the efficacy of Degradable Starch Microspheres (DSMs)-TACE with 50 ± 7 µm versus 300–500 μm Drug Eluting Beads (DEB)-TACE in terms of initial clinical and radiological treatment response parameters.Material and Methods:A total of 54 patients with unresectable HCC who underwent DEB-TACE (n = 25) or DSMs-TACE (n = 29) were included in this retrospective study. Baseline demographic and clinical characteristics, duration of follow-up, local recurrence and survival status, as well as treatment outcome including treatment response via modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria, viable and total tumor diameter and serum alpha-fetoprotein (AFP) levels were analyzed in both study groups.Results:No significant difference was noted between the two groups in terms of local recurrence (31.6 vs. 16.7%) or mortality (73.9 vs. 85.7%) rates after 36-month and 12-month follow-up, respectively. DSMs-TACE vs. DEB-TACE was associated with significantly higher complete response rate (27.6 vs. 0.0%, p = 0.011) and significant decrease in serum AFP levels (p = 0.013).Conclusion:Both DSMs-TACE with 50 ± 7 µm microspheres and 300–500 μm DEB-TACE are effective for local control of unresectable HCC. Our findings revealed superiority of DSMs-TACE over DEB-TACEnin terms of initial clinical and radiological tumor response; though no significant difference was noted between the two patient groups in terms of local recurrence or mortality during follow up. 相似文献
