Abstract

Summary: Patients treated with anti‐CD20 antibodies for haematological disorders have insufficient immune responses to mRNA COVID‐19 vaccines; however, relevant sequential data are lacking. We sequentially evaluated the humoral and cellular immune responses in 22 patients who had received anti‐CD20 antibodies within 12 months before the first vaccination, before and after the third and fourth vaccinations. Humoral responses improved gradually, along with the resolution of B‐cell depletion. A steady increase was noted in cellular responses, regardless of the B‐cell status. Our findings suggest the potential benefit of repeated vaccinations in these patients until B‐cell recovery is confirmed while enhancing cellular responses. [ABSTRACT FROM AUTHOR]

12. Clinical characteristics and risk factors for multidrug-resistant bacterial isolation in patients with international travel history.

Abstract

• We identified the risk factors for MDRO isolation among returned travelers. • ESBL E. coli (ESBLEC) was detected in about 90% of all MDRO screened patients. • The risk factors for detection were different between ESBLEC and non-ESBLEC MDRO. International travelers are at risk of carrying resistant bacteria. It is critical to identify risk factors associated with multidrug-resistant organism (MDRO) colonization in travelers. A retrospective chart review observational study was conducted at two tertiary centers in Japan for inpatients who had been hospitalized or visited an outpatient clinic overseas within the previous 12 months. These patients underwent MDRO screening upon admission. To identify independent predictors for the isolation of MDROs, multivariable analyses were performed using logistic regression. In total, 77 (36%) of the 216 patients were positive for MDROs at admission. The majority of bacteria detected in stool samples were extended-spectrum beta-lactamase-producing Escherichia coli (ESBLEC) (n = 67 [89%]). ESBLEC was detected in nearly 40% of patients who traveled to Asia. Travel to Asia was an independent risk factor for any MDRO and ESBLEC isolation. For non-ESBLEC MDRO isolation, a history of surgery abroad was an independent risk factor for detection. A history of hospitalization abroad has previously been found to be associated with MDRO colonization in travelers, which was not identified as a risk factor in this study. The risk factors for MDRO colonization were different between ESBLEC and non-ESBLEC MDROs. [ABSTRACT FROM AUTHOR]
