Tocilizumab demonstrates superiority in decreasing C-reactive protein levels in hospitalized COVID-19 patients, compared to standard care treatment alone.

Severe acute respiratory syndrome coronavirus 2 has caused a global pandemic, leading to health, economic, and political crisis. The virus triggers the activation of inflammatory reactants including interleukin-6 (IL-6), ferritin, and C-reactive protein (CRP), causing multiorgan damage, particularly affecting the lungs. Tocilizumab, an IL-6 receptor blocker, has the potential to diminish the progression of the disease and reduce organ damage and long-term complications. The aim of this observational retrospective cohort study was to evaluate the efficacy of tocilizumab in decreasing CRP levels in hospitalized coronavirus disease 2019 (COVID-19) patients compared to standard care without the drug. The study included 141 patients during their Hospital Stay (HS), with 100 in the Tocilizumab group and 41 in the non-Tocilizumab group. Clinical information was collected from the electronic clinical record, analyzed using statistical software, and homogenized the CRP levels from the severe group to the levels of the less complicated group at 48 h of hospitalization. The results showed a statistically significant greater decrease in CRP levels in the Tocilizumab group at 48 h after the use of the treatment, with no differences in mortality or length of stay between the groups. In conclusion, tocilizumab accelerates the diminishing of CRP levels compared to standard treatment alone, and its use may have potential benefits in the management of severe COVID-19 patients when used alongside with follow-up quantification of CRP levels reduction.IMPORTANCESevere acute respiratory syndrome coronavirus 2 has caused a global pandemic, leading to health, economic, and political crises. International guidelines for managing coronavirus disease 2019 (COVID-19) give recommendations according to the severity of the disease and the level of oxygen therapy needed. Tocilizumab is an option for the therapeutic management of hospitalized patients with any level of oxygen therapy; IL-6 serum level is the parameter for the follow-up on the efficacy, but it is not available at many hospitals. In this study, we demonstrate that C-reactive protein determination can predict the response to tocilizumab in severe COVID-19, the target patients for treatment with this drug. The use of this affordable and extensively available biomarker supports clinical decisions for the early escalation of the therapy and for the rational use of this drug on those prone to improve with the use of it.

Gastric variceal bleeding as a form of presentation of a pancreatic neuroendocrine tumor / Sangrado por varices gástricas como forma de presentación de un tumor neuroendocrino pancreático

NETs (neuroendocrine tumors) constitute a heterogeneous group of epithelial-type neoplasms with a predominantly neuroendocrine differentiation. Although the most common locations are the pancreas, digestive tract, and lung, this type of neoplasm can arise in virtually any organ in the body. They are rare tumors with a wide variety of clinical presentations. Symptomatic tumors are more frequent in younger patients and present at more advanced pathological stages. We present the case of a 42-year-old male with idiopathic splenomegaly and bicytopenia (anaemia and thrombocytopenia) under study by haematology department who was admitted due to an episode of melena and hemoglobin of 4.5 mg/dl. Isolated gastric varices (IGV1) with red spots were confirmed at gastroscopy and endoscopic variceal obturation using cyanoacrylate was performed in two sessions. An endoscopic ultrasonography was performed, showing thrombosis of the splenic vein extending towards the splenoportal confluence with anechoic serpiginous structures outside and inside the gastric wall suggestive of collateral circulation with gastric varices (GV). An increase in portal caliber was observed, with no signs of liver cirrhosis. Computed tomography confirms the findings. Two months/week/days later he was readmitted with rebleeding signs after starting anticoagulant treatment, so it was decided to perform a splenectomy due to failure of the endoscopic treatment. Histology revealed infiltration of the spleen by a well-differentiated neuroendocrine tumor (NET). Gallium PET/CT and Octreotid scan showed uptake in the body and tail of the pancreas with positivity for somatostatin receptors previously undetected by other means. Finally, treatment was completed with distal pancreatectomy and splenoportal axis trombectomy with vascular esplenic resection and the patient was discharged from hospital.(AU)

Double acute esophageal candidiasis and cytomegalovirus (CMV) infection in a young healthy patient: a call to think about HIV infection in AIDS.

We present an otherwise healthy 27 year-old-man who was admitted to our hospital referring acute abdominal pain, diarrhea, rectorrhagia, heavy vomiting, heartburn, dysphagia, high fever and involuntary weight loss of 12 kg in one week. An acute kidney injury, anemia and lymphopenia of 85 CD4 were observed in his blood work. The patient underwent a colonoscopy that was unremarkable. However, the oesophagogastroduodenoscopy (OGD) showed an oesophageal candidiasis in the upper oesophagus along with multiple confluent circumferential ulcerations in its lower 10 cm. Multiple biopsies were taken from the center and the edge of the ulcerations, revealing the presence of inclusion cell bodies.

Upper gastrointestinal bleeding due to duodenum diverticulum: a challenge for the endoscopist.

An 80-year-old female with a mechanic mitral valve treated with acenocumarol was admitted to the hospital due to tarry stools over the last two days and hemoglobin levels of 5.6 g/dl. She had not biliary pathology. An emergency esophagogastroduodenoscopy showed lots of fresh clots over the second part of the duodenum that seemed to come from the major papilla. A duodenoscopy was performed in order to obtain a direct view, showing a huge clot near the papilla. Its removal with a polypectomy snare revealed a large duodenum diverticulum with little saculations inside, one of which showed a visible, actively bleeding vessel. Sclerosis with epinephrine was performed and subsequently, two through-the-scope Cook® 11 mm clips were placed, achieving the cessation of the hemorrhage. Several attempts with different clips were needed since they were separated by the elevator nail of the duodenoscope. No complications developed during the procedure or once anticoagulation was restarted.

The Value of a Systematic Protocol Using Endobronchial Ultrasound and Endoscopic Ultrasound in Staging of Lung Cancer for Patients with Imaging iN0-N1 Disease.

INTRODUCTION: We hypothesize that systematic, combined, and multidisciplinary study of the mediastinum (endobronchial ultrasound [EBUS] and endoscopic ultrasound [EUS]) in patients with NSCLC with radiologically normal mediastinum improves the results of mediastinal staging obtained with EBUS alone. MATERIAL AND METHODS: A retrospective study of the prospective database collected on the patients with NSCLC with a radiologically normal mediastinum and an indication for systematic staging with EBUS and EUS. EBUS staging was followed by EUS in patients in which the results from the pathological analysis of EBUS were negative. RESULTS: Forty-five patients were included in the analysis. The combination of EBUS followed by EUS provided better results than EBUS alone: sensitivity (S) 95% versus 80%, negative predictive value (NPV) 96.15% versus 86.21%, negative likelihood ratio 0.05 versus 0.20, and post-test probability 3.8% versus 13.8%. This represents an increase in S (15%), the validity index (6.6%), and NPV (9.9%) compared to EBUS alone. There were 4 false negatives (FNs) (8.8%) with the EBUS test alone. After adding EUS, 3 more cases were positive (6.6%) and only 1 FN (2.2%). CONCLUSIONS: In patients with NSCLC and a radiographically normal mediastinum, a systematic and combined staging with EBUS and EUS show higher sensitivity in the detection of mediastinal metastasis than with the use of EBUS alone. The high accuracy of the test means that the use of mediastinoscopy is not necessary to confirm the results in these patients. Since the availability of EUS is low, it may be advisable for the interventional pulmonologist to receive training in EUS-b.

Long-term Efficacy of Perampanel in a Child with Dravet Syndrome.

Dravet syndrome is a genetic developmental and epileptic encephalopathy (DEE) mostly due to mutations in SCN1A gene. Perampanel is a selective and non-competitive alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist. There is increasing experience in the use of perampanel in this syndrome; however, there is still a lack of evidence of sustained benefit years after the beginning of the treatment. We report a twelve-year-old girl who was diagnosed with Dravet Syndrome when she was 2 years old and has been on perampanel since she was 7. Her genetic test showed a de novo previously described heterozygous SCN1A mutation in the 24th exon (c.4547C>A, p.Ser1516*). She received previous antiseizure drug combinations with little benefit. When perampanel was started, there was a complete resolution of her spontaneous seizures that has continued five years later. More studies are needed to investigate if there is an association between this excellent response and the genotype of our patient.

Inflammatory bowel disease new-onset during secukinumab therapy: real-world data from a tertiary center.

Secukinumab is a monoclonal antibody that inhibits interleukin-17A. It is currently prescribed for the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis, which are immune-mediated diseases that show significant co-heritability with inflammatory bowel disease (IBD). Although this treatment appears to be well tolerated by patients, several cases of new-onset IBD after secukinumab have been reported during the last years.

Acute neutrophilic gastritis induced by nivolumab used as treatment for non- metastatic malignant melanoma.

We present the case of a 47-year-old male with a personal history of radically removed malignant melanoma (pT3bN2M0) who was receiving adjuvant nivolumab for the prevention of recurrence. He was admitted to our service complaining of epigastric pain and hyporexia after receiving the ninth dose of nivolumab. He underwent a preferential esophagogastroduodenoscopy, which showed intense inflammation limited to the stomach.

What are the odds? Duodenum adenocarcinoma as a primary metachronic neoplasia.

We present the case of an 81-year-old male with a history of surgically resected colorectal and bladder cancer, who was admitted to our hospital with a urinary infection. A routine renal ultrasound showed a pelvic cyst and a CT scan confirmed a non-complicated cyst, but a lesion was observed in the left lung. He underwent a PET-CT in which an unexpected enhancement of the small bowel attracted our attention.

The effectiveness and safety of lacosamide in children with epilepsy in a clinical practice setting.

BACKGROUND: Seizures in up to 30% of children with epilepsy become refractory to treatment, decreasing their quality of life. Studies suggest that lacosamide may be effective in pediatric patients with refractory epilepsy. AIMS: To assess the effectiveness and safety of lacosamide in a population of children with mostly focal refractory epilepsy. METHODS: Retrospective analysis of children aged <18years presenting to a single hospital in Spain. Data from baseline, and 3, 6, and 12months after lacosamide initiation were collected and analyzed. Response to lacosamide was categorized by seizure frequency (seizure freedom or ≥75%, ≥50%, and <50% reduction in seizures). RESULTS: One hundred ninety-one pediatric patients (~55% male) with focal epilepsy treated with lacosamide were included. The mean age at lacosamide initiation was 9.4years, and the mean duration of epilepsy was 5.4years. Seizure-free rates at 3, 6, and 12months were 9.7%, 11.8%, and 16.0%. At 12months, 44.4% of the population had a ≥50% reduction in seizure frequency. When analyzing response according to the number of previous/concomitant AEDs, those patients who received ≤2 previous AEDs/fewer concomitant AEDs had significantly greater response rates than those who received greater numbers of previous/concomitant AEDs; however, no predictive factors for response were identified. The most common adverse events were seizure number increased (14.7%), diplopia (5.2%), dizziness (3.7%), ataxia (2.1%), and drowsiness (2.1%). CONCLUSIONS: Lacosamide use in children with refractory focal epilepsy can result in a reduction in seizure rate that improves progressively over time with few adverse effects, making lacosamide a promising option in these patients.
