The size of most HLNs was recorded using short-axis diameter on CT images. We did not include sex in our logistic regression analysis because of a sample-selection bias, explained by the predominance of women, who account for 80%. Demographics, clinical parameters, and absolute lymphocyte count (ALC) were collected, and their association with the presence of v-HLNs in the draining territory was studied by logistic regression.

We identified 7 BC patients who had axillary HLNs ipsilateral to the recently vaccinated arm but also ipsilateral to the known tumor. The findings of this study indicated a significant difference in outcome between lymphopenia and non-lymphopenia patients. Cureus is on a mission to change the long-standing paradigm of medical publishing, where submitting research can be costly, complex and time-consuming. 4).

Studies deciphering metabolic patterns on 18F-FDG PET/CT after vaccination are needed because annual vaccination against SARS-CoV-2 might be needed. Diabetes Metab Res Rev 2020;e3354. Four hundred forty-two patients were not vaccinated (n = 437) or did not want to participate in medical research (n = 5) and were excluded. On the basis of our findings, there is no evidence to support the conclusion that immunosuppression leads to a lower incidence of v-HLNs. Risk of thrombocytopenia and thromboembolism after covid-19 vaccination and SARS-CoV-2 positive testing: self-controlled case series study. More than half the patients were referred for BC (56%), and 24% were considered immunosuppressed (n = 62). Am J Hematol. The main limitation concerns the retrospective nature and single-center design. and transmitted securely. In the specific case of early-stage BC patients, it is usually recommended that vaccine be administered in the arm opposite the BC side. Family doctors, hematologists, breast surgeons, and radiologists must be aware of the fact that axillary, lower neck, supraclavicular, and infraclavicular lymphadenopathy may be related to the COVID-19 vaccine rather than representing actual more sinister pathologic processes. doi: 10.1002/ccr3.6317.

This study aimed to determine the role of lymphocyte levels in predicting COVID-19 patient mortality. This essential result might be the missing link between the presence of v-HLNs and vaccine effectiveness in inducing a strong immune response and, therefore, robust immunity. In this brief meta-analysis, the reduction of lymphocyte subset counts in COVID-19 patients was investigated across 2 PMC FOIA 2022 Feb 22;19(2):e1003927.

IMPLICATIONS FOR PATIENT CARE: Patients displaying a normal ALC after COVID-19 vaccination are more likely to show v-HLNs on 18F-FDG PET/CT and may subsequently have a higher seropositivity likelihood and antibody titers.

Interestingly, for patients displaying lymphopenia after vaccination, we evaluated the dynamic of ALC and found that a low ALC existed before vaccination in most patients (67%, n = 36) suggesting that lymphopenia was not related to vaccination. This site needs JavaScript to work properly. Demographics, clinical parameters, and absolute lymphocyte count (ALC) were collected, and their association with the presence of v-HLNs in the draining territory was studied by logistic regression. 2) on univariate analysis (Table 2). doi: 10.1136/bmj.m1996. In this large cohort of 260 patients, we demonstrated that patient ALC was a critical determinant of v-HLNs on 18F-FDG PET/CT after mRNA based- or viral vectorbased COVID-19 vaccination, as well as patient age and timing of last injection dose.
