Renal vein thrombosis in the course of non-operative treatment of kidney trauma: A rare case report.

INTRODUCTION: Venous thromboembolism is widely recognized as a life-threatening complication in trauma, yet renal vein thrombosis (RVT) following trauma is particularly rare. PRESENTATION OF CASE: We report a case of a 67-year-old man who was brought to the emergency department after falling down a 14-step staircase at home which presented right kidney trauma (parenchyma laceration with a perirenal hematoma) on computed tomography, and hematuria. Considering the patient's hemodynamic stability, a non-operative treatment was initiated, and the patient was referred to the intensive care unit for close observation. On post-trauma day 3, a repeated CT revealed right renal vein thrombosis. After evaluation, it was decided to maintain prophylactic anticoagulation doses of enoxaparin (40 mg/day) due to the elevated risk of bleeding in high-grade renal trauma and planned an inferior vena cava (IVC) filter placement. In the following days, the hematuria resolved spontaneously and an IVC filter was placed. The patient progressed with no complaints, spontaneous diuresis, improvement in laboratory parameters, and cardiovascular stability, which led to his discharge on day 12 with rivaroxaban 10 mg/day. The patient was successfully treated with a non-operative approach, and the RVT disappeared after 35 days. DISCUSSION: Post-traumatic renal vein thrombosis is a rare occurrence, and due to the infrequent nature of these events, specific management guidelines are not fully established, particularly when thrombosis is confirmed in an acutely injured patient. CONCLUSION: Conservative therapy seems to play a meaningful role in trauma-related renal vein thrombosis treatment.

Prediabetes Induces More Severe Acute COVID-19 Associated With IL-6 Production Without Worsening Long-Term Symptoms.

Aims: Pre-existing conditions, such as age, hypertension, obesity, and diabetes, constitute known risk factors for severe COVID-19. However, the impact of prediabetes mellitus (PDM) on COVID-19 severity is less clear. This study aimed to evaluate the influence of PDM in the acute and long-term phases of COVID-19. Materials and methods: We compared inflammatory mediators, laboratory and clinical parameters and symptoms in COVID-19 patients with prediabetes (PDM) and without diabetes (NDM) during the acute phase of infection and at three months post-hospitalization. Results: Patients with PDM had longer hospital stays and required intensive care unit admission more frequently than NDM. Upon hospitalization, PDM patients exhibited higher serum levels of interleukin 6 (IL-6), which is related to reduced partial pressure of oxygen (PaO2) in arterial blood, oxygen saturation (SpO2) and increased COVID-19 severity. However, at three months after discharge, those with PDM did not exhibit significant alterations in laboratory parameters or residual symptoms; however, PDM was observed to influence the profile of reported symptoms. Conclusions: PDM seems to be associated with increased risk of severe COVID-19, as well as higher serum levels of IL-6, which may constitute a potential biomarker of severe COVID-19 risk in affected patients. Furthermore, while PDM correlated with more severe acute-phase COVID-19, no long-term worsening of sequelae was observed.
