Defective spleen function in autoimmune gastrointestinal disorders

AbstractDefective spleen function increases susceptibility to bacterial infections which can be prevented by vaccine prophylaxis. Splenic hypofunction can be found in a number of autoimmune disorders; however, no data are available regarding autoimmune atrophic gastritis (AAG), autoimmune enteropathy (AIE) and autoimmune liver disease (AILD). Peripheral blood samples from patients with AAG (n = 40), AIE (n = 3) and AILD (n = 40) were collected. Patients affected by autoimmune disorders already known to be associated with splenic hypofunction, i.e. coeliac disease (CD) and ulcerative colitis (UC), were included as disease controls, while splenectomised patients and healthy subjects were evaluated as positive and n egative controls, respectively. Counting of erythrocytes with membrane abnormalities, i.e. pitted red cells, was used as an indicator of spleen function (normal upper limit 4%). Defective splenic function was observed in 22 of the 40 patients with AAG (55.0%), in two of the three patients with AIE ( 66.6%) and in 35 of the 40 patients with AILD (87.5%). As expected, in untreated CD, refractory CD and UC there was a high prevalence of hyposplenism (43.7%, 88.2% and 54.4%, respectively). Due to the high prevalence of splenic hypofunction, patients with AAG, AILD and AIE should undergo pitted red cell evaluation and, if hyposplenic, they should be candidate to vaccine prophylaxis against encapsulated bacteria.

Espinoza-Sánchez, Martin GötteAbstractOver the past few decades, understanding how tumor cells evade the immune system and their communication with their tumor microenvironment, has been the subject of intense investigation, with the aim of developing new cancer immunotherapies. The current therapies against cancer such as monoclonal antibodies against checkpoint inhibitors, adoptive T-cell transfer, cytokines, vaccines, and oncolytic viruses have managed to improve the clinical outcome of the patients. However,...

Abstract Checkpoint inhibitors are a form of immunotherapy that have revolutionized treatment for malignant melanoma, resulting in longer survival and better disease control. Multiple autoimmune disorders can occur with the use of checkpoint inhibitors, including severe, potentially fatal neurologic complications. Although neurologic complications are uncommon, their early recognition and treatment is required. The purpose of this article is to present information on neurologic complications of ipilimumab and nivolumab to inform nursing practice. Recommendations for evaluation and treatment of neurologic complicat...
