RESUMO

BACKGROUND: Transient positivity for hepatitis B core antibody (Anti-HBc) following intravenous immunoglobulin (IVIG) and subcutaneous immunoglobulin exposure is a well-described phenomenon. The aim of this study was to retrospectively review Hepatitis B viral screening practices in IVIG recipients in a hematology specific cohort at a single center. METHODS: Electronic databases were analyzed to identify all hematology patients who received IVIG from September 2022 to March 2022 at a single Irish center (n = 43). The proportion of patients that had a baseline anti-HBc tested prior to IVIG receipt was assessed as well as the proportion of patients that developed a transiently positive anti-HBc following IVIG exposure. Data were also collected relating to signal cut-off ratios in patients with detectable anti-HBc post-IVIG. RESULTS: 58.1% of patients had at least one serological hepatitis B viral test sent prior to IVIG exposure. Anti-HBc was the least common serological investigation performed prior to IVIG exposure (21% of recipients). A positive or equivocal "low level antibody" was identified in 15% of recipients and this was proven to be transient in all cases. CONCLUSION: The minority of hematology patients had a baseline anti-HBc assessed prior to IVIG exposure. All patients in this study had the potential to require further immunosuppressive therapies, which could be limited by a misleading anti-HBc result. We therefore advocate for baseline anti-HBc testing to be performed prior to IVIG exposure in hematology patients and for cautious interpretation of anti-HBc results taking into account signal cut-off ratios post-IVIG exposure.

RESUMO

BACKGROUND: The phenomenon of post-COVID syndrome (PCS) is evolving from an abstract array of non-specific symptoms to an identifiable clinical entity of variable severity. Its frequency and persistence have implications for service delivery and workforce planning. AIMS: This study was aimed to assess the prevalence of symptoms consistent with PCS and the subjective degree of recovery in a cohort of healthcare workers, focusing on those who have returned to work. METHODS: A study population of 1176 was surveyed when attending for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody testing. Two sub-groups were identified: those with known (i.e. diagnosed on PCR testing) and assumed (i.e. antibody evidence of previous infection) SARs-CoV-2 infection, at least 12 weeks prior to the study. Each group was asked about their subjective degree of recovery and the nature of their persistent symptoms. Results were analysed via excel and SPSS. RESULTS: In total, 144 employees showed PCR evidence of previous infection, with 139 of these being infected at least 12 weeks prior to the study. Of these 139, only 19% (n = 26) reported feeling 100% recovered, and 71% reported persistent symptoms. Of those with assumed SARS-CoV-2 infection (n = 78), 32 (41%) were truly asymptomatic since the commencement of the pandemic, while 46 (59%) described symptoms suggestive of possible infection at least 12 weeks prior to the study. Of this latter group, 23% (n = 18) also reported residual symptoms. CONCLUSIONS: PCS is prevalent among this group, including those not previously diagnosed with COVID-19. Its' frequency and duration present challenges to employers with regards to the management of work availability and performance.

RESUMO

Adherence to Clostridium difficile infection treatment guidelines is associated with lower recurrence rates and mortality as well as cost savings. This survey of Irish clinicians indicates that patients are managed using a variety of approaches. Faecal microbiota transplantation is potentially underused despite its recommendation in national and European guidelines.

RESUMO

Legionella species is a common cause of community-acquired pneumonia. However disease due to L. pneumophila serogroup 13 is rare and has not previously been reported in Ireland. It may not be detected by routine Legionella antigen and antibody kits. Due to these limitations, early culture should be considered when legionellosis is suspected. The potential therapeutic benefit of quinolones in the management of this disease is also illustrated.

RESUMO

Three experimental conditions have been used to investigate the extent to which inappropriate reflex eye movements of vestibular origin can be suppressed by visual feedback. First, the ability to read digits in a display which moved with the head was assessed during angular oscillation about the yaw and pitch axes of the body. Performance decrement was observed at frequencies above 0.2 Hz in pitch and 1.0 Hz in yaw, being greater at higher stimulus velocity levels. A second experiment revealed that the performance decrement was associated with eye movements relative to the head, which increased with the frequency of stimulation. Finally, the response of the pursuit reflex was investigated under similar experimental conditions. The results indicated that the breakdown in the pursuit reflex and in the suppression of the vestibulo-ocular reflex occurred over the same frequency band, implying the similarity of the mechanisms responsible for suppression and pursuit.
