GS, NI and RHI histopathological scoring systems are comparable in what concerns patients' stratification into histological remission/activity. Additionally, FC levels are increased when neutrophils are present in the epithelium and the intestinal mucosa has erosions or ulcers. The presence of neutrophils in the epithelium is, indeed, the main marker of histological activity.
The COVID-19 pandemic is still raging across the world and vaccination is expected to lead us out of this pandemic. Although the efficacy of the vaccines is beyond doubt, safety still remains a concern.
We report a case of a 65-year-old woman who experienced acute severe autoimmune hepatitis two weeks after receiving the first dose of Moderna-COVID-19 vaccine. Serum immunoglobulin G was elevated and antinuclear antibody was positive (1:100, speckled pattern). Liver histology showed a marked expansion of the portal tracts, severe interface hepatitis and multiple confluent foci of lobular necrosis. She started treatment with prednisolone, with a favorable clinical and analytical evolution.
Some recent reports have been suggested that COVID-19 vaccination can lead to the development of autoimmune diseases. It is speculated that the vaccine can disturb self-tolerance and trigger autoimmune responses through cross-reactivity with host cells. Therefore, healthcare providers must remain vigilant during mass COVID-19 vaccination.
This review shows how the clinical course of UC has changed over time and alerts to the need for more prospective cohort studies to evaluate long-term outcomes especially to study the impact of biologic agents on UC.
Monotherapy with azathioprine before behavior change as well as combination therapy with azathioprine and anti-TNFα before behavior change delays phenotype progression of CD, whereas upper gastrointestinal tract involvement, male gender, and steroid use with or without criteria of steroid dependence are associated with a higher risk for disease progression.
IMPORTANCE Limited evidence suggests exercise reduces blood pressure (BP) in individuals with resistant hypertension, a clinical population with low responsiveness to drug therapy. OBJECTIVE To determine whether an aerobic exercise training intervention reduces ambulatory BP among patients with resistant hypertension. DESIGN, SETTINGS, AND PARTICIPANTS The Exercise Training in the Treatment of Resistant Hypertension (EnRicH) trial is a prospective, 2-center, single-blinded randomized clinical trial performed at 2 hospital centers in Portugal from March 2017 to December 2019. A total of 60 patients with a diagnosis of resistant hypertension aged 40 to 75 years were prospectively enrolled and observed at the hospitals' hypertension outpatient clinic. INTERVENTIONS Patients were randomly assigned in a 1:1 ratio to a 12-week moderateintensity aerobic exercise training program (exercise group) or a usual care control group. The exercise group performed three 40-minute supervised sessions per week in addition to usual care.
MAIN OUTCOMES AND MEASURESThe powered primary efficacy measure was 24-hour ambulatory systolic BP change from baseline. Secondary outcomes included daytime and nighttime ambulatory BP, office BP, and cardiorespiratory fitness.RESULTS A total of 53 patients completed the study, including 26 in the exercise group and 27 in the control group. Of these, 24 (45%) were women, and the mean (SD) age was 60.1 (8.7) years. Compared with the control group, among those in the exercise group, 24-hour ambulatory systolic BP was reduced by 7.1 mm Hg (95% CI, −12.8 to −1.4; P = .02). Additionally, 24-hour ambulatory diastolic BP (−5.1 mm Hg; 95% CI, −7.9 to −2.3; P = .001), daytime systolic BP (−8.4 mm Hg; 95% CI, −14.3 to −2.5; P = .006), and daytime diastolic BP (−5.7 mm Hg; 95% CI, −9.0 to −2.4; P = .001) were reduced in the exercise group compared with the control group. Office systolic BP (−10.0 mm Hg; 95% CI, −17.6 to −2.5; P = .01) and cardiorespiratory fitness (5.05 mL/kg per minute of oxygen consumption; 95% CI, 3.5 to 6.6; P < .001) also improved in the exercise group compared with the control group.CONCLUSIONS AND RELEVANCE A 12-week aerobic exercise program reduced 24-hour and daytime ambulatory BP as well as office systolic BP in patients with resistant hypertension. These findings provide clinicians with evidence to embrace moderate-intensity aerobic exercise as a standard coadjutant therapy targeting this patient population.
This article describes cases of anti-tumor necrosis factor (TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis (AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
