No. of bitstreams: 0 Previous issue date: 2021-01-01 Cutaneous involvement is one of the most common extraintestinal manifestations of inflammatory bowel disease (IBD). More commonly, pyoderma gangrenosum and erythema nodosum are noted, but psoriasis, aphthous stomatitis, Sweet's syndrome, and vasculitis may also occur. Leukocytoclastic vasculitis (LCV) is a rare cutaneous manifestation, characterized by the appearance of palpable purpura, urticaria, and ulcer-necrotic lesions predominantly in the lower extremities that improve with immunosuppressive therapy. In this case, we report a patient with CD and LCV. We also searched the literature on the diagnosis and treatment of LCV in patients with CD. Female, 31, presented with diarrhea containing mucus and blood, abdominal pain, arthralgia, and enanthematous plaques and ulcers with a hematinic background in the lower extremities. The results of the colonoscopy were compatible with CD and skin biopsy showed signs of LCV. Systemic autoimmune disease and primary vasculitis were ruled out. The patient received treatment with a systemic corticosteroid and the skin lesions improved. Outpatient treatment with antitumor necrosis factor therapy was initiated to promote skin healing and IBD clinical remission. As LCV is a rare manifestation of IBD, it is necessary to distinguish this dermatopathy from other systemic vasculitis. The engagement of a multidisciplinary team is essential for the correct diagnosis and management.

No. of bitstreams: 0 Previous issue date: 2021-05-06 BACKGROUND Acute severe ulcerative colitis (ASUC) is a complication of ulcerative colitis associated with high levels of circulating tumor necrosis factor alpha, due to the intense inflammation and faster stool clearance of anti-tumor necrosis factor drugs. Dose-intensified infliximab treatment can be beneficial and is associated with lower rates of colectomy. The aim of the study was to present a case of a patient with ASUC and megacolon, treated with hydrocortisone and accelerated scheme of infliximab that was monitored by drug trough level. CASE SUMMARY A 22-year-old female patient diagnosed with ulcerative colitis, presented with diarrhea, rectal bleeding, abdominal pain, vomiting, and distended abdomen. During investigation, a positive toxin for Clostridium difficile and colonic dilatation of 7 cm consistent with megacolon were observed. She was treated with oral vancomycin for pseudomembranous colitis and intravenous hydrocortisone for severe colitis, which led to the resolution of megacolon. Due to the persistent severe colitis symptoms, infliximab 5 mg/kg was prescribed, monitored by drug trough level (8.8 mu g/mL) and fecal calprotectin of 921 mu g/g (< 30 mu g/g). Based on the low infliximab trough level after one week from the first infliximab dose, the patient received a second infusion at week 1, consistent with the accelerated regimen (infusions at weeks 0, 1, 2 and 6). We achieved a positive clinical and endoscopic response after 6 mo of therapy, without the need for a colectomy. CONCLUSION Infliximab accelerated infusions can be beneficial in ASUC unresponsive to the treatment with intravenous corticosteroids. Longitudinal studies are necessary to define the best therapeutic drug monitoring and treatment regimen for these patients.

Hepatocellular carcinoma is a relevant cause of mortality worldwide, mainly among patients who have a prior liver disease. In spite of clear recommendations regarding surveillance and screening methods, most patients are still diagnosed only when they are no longer candidates to curative treatment modalities, while others do not achieve the goals of such treatments, thus increasing the need of anticancer drugs. Moreover, when cirrhotic patients begin to receive these drugs, many types of adverse events are seen as a reason to withdrawal, even when there are findings suggesting a good response to the treatment. Case Summary. This case report is about a cirrhotic patient who received many types of treatment, from surgery and chemoembolization during early stages to first- and second-line systemic therapy when the disease turned to be advanced. Since he had no signs of liver dysfunction and suffered tumor progression during sorafenib treatment, regorafenib was initiated. The main findings that make this case important are the adverse events after taking this second-line agent, which would certainly be considered unacceptable and would lead to the drug withdrawal. The reasons why regorafenib was maintained are explained based on clinical and imaging findings, showing how this decision led to an excellent response. Conclusions. The knowledge of the main adverse events described in the pilot clinical trials can avoid unnecessary withdrawal of regorafenib. In addition, some clinical and imaging findings can be deemed as predictors of good response to tyrosine kinase inhibitors.
