Lipemic plasma donations are not a strange phenomenon to blood bankers. According to quality standards for plasma fractionation, lipemic plasma donations must be discarded. Beyond quality control and inventory aspects, plasma lipemia is also an important risk factor for cardiovascular diseases, acute pancreatitis and is associated with overall mortality, however little attention is given to the management of these donors in the literature. A retrospective analysis of every whole blood donation that yielded lipemic plasma between January 1st 2018 and December 31st 2019 was made. The medical examination and donor history for the respective donation was reviewed and the available data was collected regarding hour of donation, gender, age, drugs and coexisting pathologies. Whether the donor was called back for a follow up evaluation regarding the lipemic plasma was also noted. Our blood center received 18274 whole blood donations of which 115 (0,63 %) were reported as having plasma lipemia, in the period of this study. Of these 115 donors, 103 (89,57 %) were male. The average age was 47,63 ± 10,65 years. A clear peak in lipemic plasma donations 4 hours after the classic lunch hours is visible. For 88,70 % of the donors, this was the first time their hypertriglyceridemia was identified. The nonfasting elevation of plasma triglycerides in these donors represents a true metabolic derangement. This is a golden opportunity for early intervention and follow up evaluation is indicated. More attention must be given during the medical evaluation to properly identify donors at risk of lipemic donations.
A trombocitopenia é um reconhecido efeito secundário a vários fármacos, alimentos, bebidas e produtos de ervanárias.A piperacillina/tazobactam é uma combinação betalactâmico/inibidor da betalactamase de amplo espectro anti-bacteriano, associada a vários efeitos adversos a nível hematológico, sendo o mais frequentemente reportado a neutropenia reversível, mas a anemia hemolítica Coombs positiva e a trombocitopenia também são descritas. Reporta-se um caso clínico de um homem, 73 anos, que desenvolveu trombocitopenia grave induzida pela exposição a piperacilina/tazobactam, confirmada posteriormente pela reexposição ao fármaco.
Patients with Coronavirus disease 2019 (COVID-19) are at increased risk of venous thromboembolism (VTE); however, data on arterial thromboembolism (ATE) is still limited. We report a case series of thromboembolic events (TE) in 290 COVID-19 patients admitted between October and December 2020 to a Portuguese hospital. Admission levels of various laboratory parameters were evaluated and compared between COVID-19 patients with (TE) and without thrombotic events (non-TE). The overall incidence of isolated ATE was 5.52%, isolated VTE was 2.41% and multiple mixed events was 0.7%. A total of 68% events were detected upon admission to the hospital with 76% corresponding to ATE. Admissions to the Intensive Care Unit were higher in patients with TE, when comparing with the non-TE group (44% vs. 27.2%; p = 0.003). Patients with ATE presented significantly lower levels of CRP (p = 0.007), ferritin (p = 0.045), LDH (p = 0.037), fibrinogen (p = 0.010) and higher monocyte counts (p = 0.033) comparatively to the non-TE patients. These results point to an early occurrence of TE and an increased incidence of ATE over VTE. The less prominent inflammation markers in patients with TE and the early presence of TE in patients with otherwise no reason for hospitalization, may suggest a direct role of SARS-CoV-2 in the thrombotic process.

The COVID-19 pandemic is currently responsible for over 526 million infections and over 6.3 million deaths. As a new disease, the number of papers on the subject is extensive, motivating considerable heterogeneity in its approach. Despite some medicines having sound evidence of benefit, new interventions and strategies continue to be proposed, and some still lack scientific evidence, which hinders a uniform and consensual approach. This article aims to standardize healthcare to adult patients with moderate-to-critical COVID-19, from the emergency department to hospitalization, either in a general ward or in level 2 or level 3 intensive care units, based on the best and most updated scientific evidence available. This protocol presents recommendations for the stratification of adult patients with COVID-19 disease, adequate workup at admission and during hospitalization, inpatient treatment criteria, general treatment measures, pharmacological treatment, management of complications such as organizing pneumonia and bacterial superinfection, thromboprophylaxis, special considerations on pregnancy and breastfeeding and possible future therapies.
