Antibody responses after first and second Covid-19 vaccination in patients with chronic lymphocytic leukaemia

B-cell chronic lymphocytic leukaemia (CLL) is associated with immunosuppression and patients are at increased clinical risk following SARS-CoV-2 infection. Covid-19 vaccines offer the potential for protection against severe infection but relatively little is known regarding the profile of the antibody response following first or second vaccination. We studied spike-specific antibody responses following first and/or second Covid-19 vaccination in 299 patients with CLL compared with healthy donors. 286 patients underwent extended interval (10-12 week) vaccination. 154 patients received the BNT162b2 mRNA vaccine and 145 patients received ChAdOx1. Blood samples were taken either by venepuncture or as dried blood spots on filter paper. Spike-specific antibody responses were detectable in 34% of patients with CLL after one vaccine (n = 267) compared to 94% in healthy donors with antibody titres 104-fold lower in the patient group. Antibody responses increased to 75% after second vaccine (n = 55), compared to 100% in healthy donors, although titres remained lower. Multivariate analysis showed that current treatment with BTK inhibitors or IgA deficiency were independently associated with failure to generate an antibody response after the second vaccine. This work supports the need for optimisation of vaccination strategy in patients with CLL including the potential utility of booster vaccines.

The impact of medical students on rural general practitioner perceptors

INTRODUCTION

As universities rely more heavily on rural GPs to precept medical students, the formation of symbiotic partnerships benefiting students, universities and GPs, becomes imperative. In order to develop and consolidate these partnerships Universities must understand who their rural GP preceptors are and how precepting impacts on them.

METHODS

A review of the literature was undertaken to determine the significant themes of student impacts from articles where conclusions were clearly based on empirical findings.

RESULTS

Forty-three articles were included in the final review, but only nine specifically looked at impacts on rural GPs. Impacts were categorised into six domains: personal; time; patient care; professional relationships and professional development; business and infrastructure; and recognition and remuneration.

CONCLUSIONS

Literature specifically addressing the impact of precepting on rural GPs is scarce. Further studies are required to evaluate the relationship between the quality of teaching delivered to students, the type and length of student attachments and the likely impacts on rural GPs.
