RESUMO
CASE: Background: CD is an inflammatory disease that predominantly affects the gastrointestinal tract and has a progressive course. Immunodeficiencies can occur by altering different components of innate or adaptive immune responses. Such changes put the patient at greater risk for infectious diseases or non-infectious complications. Among the non-infectious complications are cancer, autoimmune diseases and gastrointestinal diseases, which should be suspected in patients with recurrent infections, with clinical, radiological or histological features of the disease are atypical or in the occurrence of an unsatisfactory response to conventional therapy. OBJECTIVE: To describe a case report of a CD patient complicated with enteric alterations related to immunodeficiency. RESULTS: A 31-year-old male patient started presenting abdominal pain, diarrhea, and weight loss in October 2020. He underwent a colonoscopy that showed diffuse involvement of the colon suggestive of CD. He didn`t respond to therapy with prednisone and azathioprine and lost 40kg until January 2021, when he was referred to an IBD center. He had signs of malnutrition (eg, BMI = 15.4, Albumin = 1.8g/dL). The MRI showed diffuse thickening of the walls of the entire length of the ileum, colon and rectum, associated with submucosal edema and more intense enhancement in the inner layer. Findings compatible with nonspecific diffuse ileocolitis. After negative infectious screening, hydrocortisone, azathioprine and infliximab were prescribed, but the patient remained clinical worsening. During the 6 weeks of therapy use, the patient presented oral candidiasis, septic pyoarthritis, DNA testing for Clostridium difficile and PCR for Cytomegalovius were positive. Despite the treatment of infectious diseases, the patient continued to worsen and was considered a primary non-response to anti-TNF, opting for the initiation of Ustekinumab. There was improvement in endoscopic and fecal calprotectin, but continued progression of ileal disease and diarrhea, with no response to enteral or parenteral nutritional therapies. An investigation for immunodeficiencies was carried out and IgM/IgG deficiency was noted, and parenteral immunoglobulin was started. He presented an intestinal subocclusion, requiring a loop ileostomy. In this surgery, it was decided to send a sample of ileal tissue for diagnostic differentiation, where ileitis was observed with intense plasma cell reaction and lymphoid nodular hyperplasia, uncharacteristic of DC, which may correspond to enteropathy secondary to immunodeficiency. Despite the treatment, the patient presented fungal endocarditis, esophageal moniliasis and septic condition of undetermined origin. He remained in hospital for 120 days until complete improvement of the infectious complications. With the slow improvement in nutritional parameters, there was a reduction in the incidence of infections as well as an increase in immunoglobulins. After five months of combined nutrition and anti-interleukin therapy, the patient presented clinical improvement, weight gain and complete normalization of IgG and IgM. Ileal disease is in regression and in the colon, in endoscopic remission. CONCLUSION: We present a case report of the initial presentation of DC complicated with severe malnutrition where there was depletion of part of immunoglobulins, resulting in infectious and non-infectious complications, where ileal involvement intensified the manifestation of colonic DC.
RESUMO
INTRODUCTION: Bacterial infection is present in up to 30% of hospitalized cirrhotic patients. It can lead, even after its resolution, to organ dysfunction and even acute-on-chronic liver failure (ACLF). It is the precipitating factor of ACLF in one third of the cases and is the main cause of mortality in patients with liver cirrhosis. OBJECTIVES: The aim of this study was to evaluate the prevalence and identify early risk factors for severe ACLF and death in hospitalized patients with liver cirrhosis with bacterial infection. PATIENTS AND METHODS: This was a prospective observational study. Hospitalized patients with liver cirrhosis and bacterial infection were included. Clinical and laboratory data and their evolution to organ dysfunction and death were assessed. A statistical analysis were carried out to identify predictors of severe ACLF and in-hospital mortality. RESULTS: This study included 88 patients. ACLF was observed in 62 (70%) patients, with 48 (55%) grade 2 or higher. Of the 27 deaths (31% of all patients), 26 had severe ACLF (54% mortality) (P<0.0001). The independent risk factors for ACLF of at least 2 and death were baseline serum sodium [odds ratio (OR): 0.874; P=0.01, and OR: 0.9, P=0.04], initial MELD (OR: 1.255, P=0.0001, and OR: 1.162, P=0.005), and a recent invasive procedure (OR: 3.169, P=0.01, and OR: 6.648, P=0.003). CONCLUSION: Lower serum sodium values, higher MELD scores at diagnosis of infection, and a recent history of invasive procedures were independent risk factors for severe ACLF and death in patients with cirrhosis and bacterial infection.
