Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.
The objectives of this study were to describe and compare the clinical characteristics of ankylosing spondylitis (AS) and undifferentiated spondyloarthritis (USpA) in Middle East Arab (MEA) and South Asian (SA) patients diagnosed in our unit. Fifty-eight consecutive patients diagnosed with SpA were studied after classifying them into MEA and SA. They were further classified as per disease diagnosis. Excluding three patients with miscellaneous ethnicity, there were 29 MEA and 26 SA patients. Seventy-two percent of MEA patients were males (vs 92% of SA patients). Of the 29 patients with MEA ethnicity, 17 had AS and 9 had USpA. Of the 26 patients with SA ethnicity, 10 had AS and 14 had USpA. Fifty-nine percent of MEA patients had AS (vs 39% of SA patients). Mean age at onset in AS patients was similar in the two ethnic groups. However, in patients with USpA, mean age at onset was somewhat lower at 21.8 years in the MEA group compared with 29.4 years in the SA group. Family history in first-degree relatives was significantly more common in MEA patients. Weight loss, inflammatory spinal pain, gluteal pain, and enthesopathy were equally common in both ethnic groups. Knee, ankle, and metatarsophalangeal joint involvement was less common in MEA patients. There were no significant differences in the occurrence of syndesmophytes, bamboo spine, and sacroiliitis in the two ethnic groups. HLA-B27 positivity rates in MEA patients were 87% for AS and 67% for USpA compared to 75 and 71%, respectively, in SA patients. It is concluded that some significant new findings have arisen from this study: the majority of MEA patients presented with AS, whereas the majority of SA patients had a picture of USpA. Family history was more common in MEA patients. Peripheral arthritis was less common in MEA patients. Worldwide, this is the first study to show that there are significant differences in the clinical expression of the various SpA in MEA patients compared to SA patients.
