Ferric carboxymaltose for anemia in Crohn’s disease patients at a tertiary center:A retrospective observational cohort study

BACKGROUND Although the gastrointestinal tract is the most affected by Crohn’s disease(CD),the condition triggers other consequent manifestations,and iron deficiency anemia(IDA)is one of the most common.Intravenous(IV)iron replacement is currently available through several drugs,such as ferric hydroxide sucrose and ferric carboxymaltose(FCM).However,the clinical management of these conditions can be challenging.AIM To elucidate the drug’s effectiveness,the present study analyzed,through medical records,the clinical and epidemiological data of a cohort of patients with active CD who received IV FCM for the IDA treatment.METHODS This retrospective observational study included 25 patients with active CD,severe anemia,and refractory to previous conventional treatments.Patients were evaluated two times:During the last treatment with ferric hydroxide sucrose and treatment with FCM.RESULTS After treatment with FCM,parameters of IDA assessment significantly improved,serum hemoglobin(Hb)levels increased in 93%of patients(P<0.0001),and in 44%,there was an increase of≥2 g/dL in a single application.In addition,86%of the patients showed an increase in serum iron(P<0.0001)and ferritin(P=0.0008)and 50%in transferrin saturation(P=0.01).The serum iron levels at baseline showed a negative association with the ileal and colonic CD and use of biologics and a positive association with patients who developed CD later in life after the age of 40(A3)and with a stenosing(B2)and fistulizing(B3)phenotype.The values of Hb and hematocrit after ferric hydroxide sucrose treatment remained similar to those found before treatment.CONCLUSION This study demonstrated that FCM is an important therapeutic strategy for treating IDA in CD patients,achieving satisfactory results in refractory cases.

Assessment of disease activity in inflammatory bowel diseases:Non-invasive biomarkers and endoscopic scores

Inflammatory bowel diseases(IBD)comprise two major forms:Crohn’s disease and ulcerative colitis.The diagnosis of IBD is based on clinical symptoms combined with results found in endoscopic and radiological examinations.In addition,the discovery of biomarkers has significantly improved the diagnosis and management of IBD.Several potential genetic,serological,fecal,microbial,histological and immunological biomarkers have been proposed for IBD,and they have been evaluated for clinical routine and clinical trials.Ileocolonoscopy,especially with biopsy collection,has been considered the standard method to diagnose IBD and to assess clinical activity of the disease,but it is limited to the colon and terminal ileum and is considered invasive.For this reason,non-invasive biomarkers are necessary for this type of chronic inflammatory disease,which affects mostly young individuals,as they are expected to have a long follow-up.

Impact of infection in hospitalized cirrhotic patients in a university hospital

Background: Infection increases the morbidity and mortality in liver cirrhosis patients. The aim of this study was to investigate the impact of infection related to survival and risk factors for death in adult patients with liver cirrhosis in a university hospital. Methods: In a retrospective cohort study of Brazilian hospitalized cirrhotic patients, medical records data were analysed, and all patients who have had one or more confirmed bacterial infection during admission were se-ected for the study. Also, some data as biochemical investigation, Child score, MELD estimation, and evolution and death event were included. Statistical analysis: chi-square, Fisher and Mann-Whitney tests were used. Uni and multivariate analysis were performed, according to Cox regression model. The significant statistical level was p 2.5 mg/dl had increased the risk of death of 4.1, 3.2 and 3.2, respectively. Conclusion: Bacterial infections in hospitalized cirrhotic patients deserve special care, mainly spontaneous bacterial peritonitis, and also patients whose hiponatremia, upper gastrointestinal bleeding, high levels of cre-atinine and MELD high score are found.

Gastrointestinal tuberculosis:An autopsy-based study

Background:Tuberculosis is a disease of great relevance since it is one of the leading causes of morbidity and mortality worldwide.Gastrointestinal tuberculosis is an unusual presentation.It is defined as the involvement of any segment of the digestive tract,associated viscera,and peritoneum.The study’s main objective is to collect information from autopsies of patients diagnosed with gastrointestinal tuberculosis in a Pathology reference center in Colombia.Methods:This is a retrospective and descriptive study of autopsy reports.A total of 4,500 autopsies were performed between January 2004 and December 2020.The inclusion criteria were authorization of a family member following local law regulations and a final autopsy diagnosis of gastrointestinal tuberculosis using microscopic visualization.Results:Forty-eight patients with gastrointestinal tuberculosis autopsies were included in our study.Most of the patients were male(n=35,72.9%)with a median age of 40.5 years old.Human immunodeficiency virus infection history was reported in 28 cases(58.33%).The most affected gastrointestinal tract site was the terminal ileum.Ulcers and thickened epithelium were common autopsies macroscopic findings.Tuberculosis multiorgan compromise was a relevant finding in patients with gastrointestinal tuberculosis.Conclusions:Gastrointestinal tuberculosis is a disease of great importance,being its diagnosis a clinical challenge.Underdiagnosis can be reported in a high percentage of cases,so autopsy diagnosis can help reveal more accurate data about this condition.
