ABSTRACT

BACKGROUND/AIMS: In Crohn's disease (CD) few data are available on the usefulness of monitoring fecal calprotectin (FC) in the early postoperative setting. We assessed prospectively the accuracy of FC measured 3 months after surgery to predict the risk of endoscopic postoperative recurrence (POR) within 1 year after resection. METHODS: In 55 consecutive CD patients who had undergone ileocolonic resection samples were collected 3 months after surgery for measuring serum CRP and FC. Endoscopic POR was assessed by ileocolonoscopy within 6-12 months (median 7 months). Receiver operating characteristic (ROC) curves were generated to assess accuracy of the markers, to determine the best threshold and to calculate sensitivity, specificity, positive and negative predictive values. RESULTS: In contrast with median CRP levels, median FC concentrations measured 3 months after surgery were significantly higher in patients who later experienced endoscopic POR (Rutgeerts ≥ i2) compared with those who stayed in endoscopic remission within the following 6-12 months (205 µg/g IQR [106-721] vs. 103 µg/g IQR [60-219], p = 0.008). Area under the ROC curve for FC was 0.71. The best cutoff value of FC to identify patients in subsequent endoscopic remission 3 months after surgery was 65 µg/g (96% sensitivity, 31% specificity, 50% positive and 91% negative predictive values). In multivariate analysis, FC < 65 µg/g at 3 months was the only factor associated with subsequent endoscopic remission. CONCLUSION: FC measured 3 months after surgery below 65 µg/g is an accurate marker to identify CD patients who will later stay in endoscopic remission within 1 year after resection.

ABSTRACT

INTRODUCTION: Few cases of arterial thromboembolisms have been reported after novel coronavirus disease 2019 (COVID-19) in case of severe infection or in elderly patients. We report a case of femoral arterial thrombosis in a young patient after nonsevere infection. CASE DESCRIPTION: A common femoral artery thrombosis extended in the first third of superficial and profunda femoral arteries associated with tibial posterior and popliteal artery thrombosis was diagnosed in a 24-year-old man complaining of right lower limb pain for one month. The evolution was good after anticoagulation and antiaggregant treatments and thrombectomy. Etiologic assessment was negative except for nonsevere COVID-19. DISCUSSION: COVID-19 accesses host cells via angiotensin-converting enzyme 2 protein, abundant in the lungs, which is also expressed by endothelial cells and is associated with important inflammatory syndrome and coagulopathy, leading to vascular lesions. Thrombosis prevalence is not fully established and seems to be higher in case of major inflammation and in the intensive care unit (ICU). Arterial thromboembolisms are described in many vascular territories, each time in elderly patients, or in case of severe infection. We described a femoral arterial thrombosis in a young patient with negative etiological assessment except nonsevere COVID-19. Treatment consists in anticoagulation and antiaggregant drugs and thrombectomy. Preventing venous thromboembolism treatment is recommended in case of severe infection or in the ICU, but there is no clear recommendation for arterial thromboembolism prevention. This case should lead us to be very careful of the arterial event risk even if the infection is nonsevere and the patient is young.
