Haemorrhagic ulcerative duodenitis in a patient with COVID-19 infection: clinical improvement following treatment with budesonide.

We present a case of a male patient in his mid-30s with COVID-19-induced lung failure requiring extracorporeal membrane oxygenation, who needed an emergency oesophagogastroduodenoscopy due to major upper gastrointestinal bleeding. Endoscopy exposed severe ulcerative duodenitis with diffuse mucosal bleeding. While CT angiography did not show any signs of ischaemia, histopathology revealed duodenitis with substantial inflammatory cell infiltrates consisting of neutrophils and CD3+ T lymphocytes with equal CD4+/CD8+ distribution. Since the composition of cell infiltrates coincides with changes in inflammatory patterns of the respiratory mucosa from patients with COVID-19 and in COVID-19-associated enterocolitis, and systemic dexamethasone treatment became standard of care in ventilated intensive care unit patients with COVID-19 infection, we initiated an individualised therapeutic attempt to treat the duodenitis with topical enteral budesonide. Follow-up oesophagogastroduodenoscopies within 4 weeks of enteral budesonide administration revealed a full clinical and histological healing of the duodenal mucosa with marked reduction of neutrophilic and lymphocytic infiltrates.To our knowledge, the current report is the first description of enteral budesonide treatment of duodenitis in a patient with COVID-19 infection and warrants further investigation, whether budesonide might constitute a novel therapeutic strategy for the management of COVID-19-related intestinal mucosal damage.

Atypical presentation of a locally advanced hepatocellular carcinoma: Extensive workup of an incidental finding on computed tomography performed for planning of transcatheter aortic valve implantation.

This case report presents the diagnostic workup of liver malignancy incidentally detected in a 72-year-old male patient on routine body computed tomography angiography (CTA) performed for planning transcatheter aortic valve implantation (TAVI). The patient initially presented to an outside hospital with chest discomfort, where routine diagnostic procedures in the emergency room revealed grade III aortic valve stenosis. Routine CTA for TAVI planning in our department then revealed tumor thrombosis of the portal vein suspicious for hepatic malignancy. In contrast-enhanced ultrasound (CEUS) only the left hepatic lobe was inhomogeneously transformed with early arterial contrast enhancement. Magnetic resonance imaging (MRI) confirmed a primary hepatic malignancy involving the left liver. Transcutaneous biopsy with ultrasound guidance established the diagnosis of hepatocellular carcinoma (HCC). Incidental findings may be of prognostic relevance for the patient and in a number of cases, TAVI can be a prerequisite for the appropriate therapy.

Low-dose growth hormone is cardioprotective in uremia.

Growth hormone (GH) is required to maintain normal cardiac structure and function and has a positive effect on cardiac remodeling in experimental and possibly human disease. Cardiac resistance to GH develops in the uremic state, perhaps predisposing to the characteristic cardiomyopathy associated with uremia. It was hypothesized that administration of low-dosage GH may have a salutary effect on the cardiac remodeling process in uremia, but because high levels of GH have adverse cardiac effects, administration of high-dosage GH may worsen uremic cardiomyopathy. In rats with chronic renal failure, quantitative cardiac morphology revealed a decrease in total capillary length and capillary length density and an increase in mean intercapillary distance and fibroblast volume density evident. Low-dosage GH prevented these changes. Collagen and TGF-beta immunostaining, increased in chronic renal failure, were also reduced by GH, suggesting a mechanism for its salutary action. Low-dosage GH also prevented thickening of the carotid artery but did not affect aortic pathology. In contrast, high-dosage GH worsened several of these variables. These results suggest that low-dosage GH may benefit the heart and possibly the carotid arteries in chronic renal failure.
