This study intends to quantify the incidence of acro-ischemic lesions in COVID-19 infected adult subjects in our population, describing clinical patterns and associated findings. Methods: All adult confirmed cases of COVID-19 infection who presented with acroischemic lesions and received care in our institution were prospectively enrolled up to May 15th, 2020. The variables included demographics, comorbidities, analytical parameters, clinical presentations and COVID-19 treatment. Results: We enrolled 24 patients. The overall rate of acro-ischemic findings in COVID-19 patients was 1.2% [0.6% for outpatients and 2.9% for hospitalized (ICU and non-ICU patients)], but the observed incidence for acro-ischemia in ICU patients was remarkably higher (23.0%, p<0.001). We have described four different clinical patterns of acroischemia: atypical Raynaud´s phenomenon (ARP), (4); pseudo-pernio (PP), (5); severe microcirculatory ischemia with preserved pulse (SMI), (6); and dry gangrene with arteriosclerosis obliterans (AO), (9). Kendall´s τ correlation with lung disease severity was 0.877 (95% CI, 0.756 to 0.968); p<0.01). ARP individuals were predominantly female, while SMI appeared lately in elderly hospitalized subjects with better prognosis. AO occurred in patients with more comorbidity and younger than those with SMI. We observed other associated lesions of suggestive ischemic nature in other organs in all groups (15 patients of total sample). Plasma procalcitonin was significantly higher in patients who developed SMI (median and interquartile range: 9.99 (4.2, 12.3) mg/mL vs 0.26 (0.11, 0.89) mg/mL; p<0.001), and D-dimer level at hospital admission was significantly higher in AO patients (median and interquartile range: 1166 (1050, 2111) mg/L vs 502 (448, 777) mg/L; p<0.001). Conclusion: The observed risk for acroischemia in COVID-19 is high in ICU patients (23%). We have described four different clinical patterns of acroischemia (ARP, PP, SMI and AO) associated with lung disease severity. Authors have communicated various lesions of suggestive ischemic nature in other organs. Raynaud-like pattern is reported as a "novelty".

There is an increasing evidence supporting the existence of coagulopathy in coronavirus disease 2019 (COVID-19) patients. Most of reports are mainly focused on d-dimer. Our objective is to describe coagulation parameters in these patients that could be involved in a hypercoagulate state and to test platelet function to see if there are short closure times. We analyzed coagulation samples from 80 patients admitted with COVID-19 in our hospital. We also tested platelet function by closure times in a small subgroup of patients. Most of samples had increased d-dimer (96.2%) (median of d-dimer: 1158 ng/ml FEU), increased fibrinogen (75.2%) (median: 5.23 g/l), increased factor VIII (86%) (median: 264.8 U/dl), decreased protein S (22.5% of women, 62.5% of men) (median: 62.8 and 68.5 U/dl, respectively), decreased protein C (7.6%) (median: 100 U/dl), decreased factor XII (25.3%) (median: 90.3 U/dl) and decreased antithrombin activity (21%) (median: 86 U/dl). International normalized ratio was higher than normal in 24 patients (30%) (median: 1.13). The activated partial thromboplastin time ratio was below the normal range in nine patients (11.2%) and above normal in three (3.75%) (median: 0.93). The closure times were short in the 20% and 40% of samples of collagen and ADP and collagen and epinephrine, respectively. Twelve of the 80 patients (15%) had a thrombotic event and all had several abnormal coagulation parameters related with increased thrombotic risk. The results of this study support a hypercoagulability state in COVID-19 patients and it may help to explain the microvascular thrombosis caused by the inflammatory response.

Background COVID-19 related in-hospital venous thromboembolism (VTE) incidence is high but data reported vary significantly. Some studies show that up to half of the events are diagnosed early after admission. Objectives To study symptomatic VTE incidence in acute COVID-19 hospitalized patients and to describe timing of VTE diagnosis. Methods Multicenter cohort of 5966 patients hospitalized with acute COVID-19. Multicenter Registry of 844 hospitalized patients with acute COVID-19 and associated acute VTE. Results By the time of cohort data collection, 68 patients (1.14%) were still hospitalized, 19.8% had died, and 5.4% required ICU. During a median follow-up of 6 days (IQR, 4–12), 183 patients (3.07%; 95% CI, 2.64–3.55) presented a symptomatic VTE event. The cumulative incidences of VTE at 7, 14 and 21 days in wards [2.3% (95% CI, 1.9–2.7), 3.6% (95% CI, 3.0–4.3), and 4.3% (95% CI, 3.5–5.1)] were similar to the ones reported in ICU [2.2% (95% CI, 1.0–4.4), 2.9% (95% CI, 1.5–5.3), and 4.1% (95% CI, 2.2–6.8)], but at 30 and 60 days were higher in ICU [6.9% (95% CI, 4.2–10.5), and 12.8% (95% CI, 8.1–18.5)] than in wards. Eighty-eight VTE events (48%) were diagnosed early, within 48 h of admission. VTE was not associated with death (HR, 0.79; 95% CI, 0.55–1.12). Conclusions Incidence of symptomatic VTE in our COVID-19 cohort is consistent with that of other real-life studies recently published. Early VTE events are, along with COVID-19, the reason for admission rather than an in-hospital complication.
