BACKGROUND: The Bacillus Calmette-Guerin vaccine (BCG) has been associated with beneficial nonspecific effects on infant health. We aimed to examine the effect of BCG at birth on thymic size and the associations between thymic output, circulating lymphocytes, risk of infection, and thymic size. METHODS: In infants' randomized to BCG or no BCG, thymic index (TI), and thymic/weight index (TWI) were measured by ultrasound at birth and at the age of 3 mo. T cell subpopulations including CD4(+) T cells, CD8(+) T cells, and recent thymic emigrants (RTEs) were assessed by flow cytometry. Infections up to age 3 mo were parent-reported. RESULTS: BCG vaccination did not affect thymic size at age 3 mo, measured as TI. At birth, the number of lymphocytes, CD4(+) T cells, CD8(+) T cells, and RTEs were positively associated with TI and TWI. Furthermore, a reduced risk of infections up to age 3 mo was associated with a large thymic size at birth. CONCLUSION: We found no effect of BCG vaccination on thymic size. The positive association between thymic output, lymphocytes, reduced risk of infections, and TI/TWI suggests that assessment of TI/TWI by ultrasound may be a predictor of the immunological capacity in the newborn.

Faster lung function decline in people living with HIV despite adequate treatment: a longitudinal matched cohort study

Rebekka Faber Thudium, Andreas Ronit, Shoaib Afzal, Yunus Colak, Julie Lyng Forman, Fernando Mendo, Fabian Chen, Vicente Estrada, Nagalingeswaran Kumarasamy, Borge G. Nordestgaard, Jens Lundgren, Jorgen Vestbo, Ken M. Kunisaki, Susanne Dam Nielsen

Summary: This study compared the decline in lung function between people living with HIV who receive antiretroviral therapy and matched controls, and found that well-treated PLWH have faster lung function decline than controls. Smoking seems to modify this association, suggesting that smoking may lead to more rapid lung function decline in PLWH than in controls.

Moises Alberto Suarez-Zdunek, Sunil Kumar Saini, Christian Ross Pedersen, Sebastian Rask Hamm, Annemette Hald, Allan Rasmussen, Jens Georg Hillingso, Sine Reker Hadrup, Susanne Dam Nielsen

Summary: This study aims to explore the cellular immune response against CMV and VZV infections in liver transplant recipients and identify potential risk factors for infection. Through an epidemiological substudy and an immunological substudy, the incidence and clinical risk factors for CMV and VZV infections will be determined, and the frequency, T cell receptor sequences, and phenotypic characteristics of CMV- and VZV-specific T cells will be examined. The study has the potential to develop a prediction model and proof-of-concept for adoptive T cell therapy against CMV and VZV to reduce the burden and consequence of infections in liver transplant recipients.

Summary: Long-term opioid treatment (L-TOT) for chronic non-cancer pain (CNCP) may result in endocrine dysfunction, including changes in testosterone, growth hormone, and prolactin levels. This study found that compared to CNCP patients not receiving opioids, those on L-TOT had lower testosterone and growth hormone levels, as well as higher prolactin levels. Additionally, a correlation was observed between high opioid dose and low growth hormone levels.

Summary: Multiomics technologies were used to stratify and characterize the metabolic risk profile in people living with HIV (PWH) on antiretroviral therapy. Through network analysis and similarity network fusion (SNF), three groups of PWH were identified: healthy-like, mild at-risk, and severe at-risk. PWH in the severe at-risk group had a high incidence of metabolic syndrome and dysregulated metabolic traits, despite having higher CD4(+) T-cell counts. The microbiome profile differed between the healthy-like group and the at-risk groups, potentially contributing to systemic inflammation and cardiometabolic risk.

Summary: This study investigated the changes in symptom-specific hospital contacts among 12-18-year-olds following two doses of BNT162b2 COVID-19 vaccine compared to unvaccinated peers. National register data was used to match vaccinated and unvaccinated adolescents based on sex and age. Differences between the vaccinated and unvaccinated were found in symptom-specific hospital contacts, with higher rates observed for some symptoms among the vaccinated and higher rates for others among the unvaccinated. Monitoring of specific symptoms is important post-vaccination, considering the risk of infection and symptoms following COVID-19 infection.

Summary: The complexity of immune responses to SARS-CoV-2 has increased over time, with diverse immune imprinting observed in vaccinated individuals. Our study found that both humoral and cellular responses were generally higher after SARS-CoV-2 infection compared to infection-naive individuals. Pre-vaccination viral exposure was crucial for achieving a robust IgA response. Lower IgG, IgA, and neutralizing antibody responses post-vaccination were associated with a significantly higher risk of reinfection and future Omicron infections. However, T-cell responses did not show the same association. Primary infection before Omicron and subsequent reinfection dampened the humoral and cellular responses compared to a primary Omicron infection, consistent with immune imprinting.

Summary: This study investigated the long-term durability of humoral and cellular immune responses to the third dose of BNT162b2 in people with HIV and controls. The results showed that before the third dose, HIV patients had lower concentrations of SARS-CoV-2 antibodies compared to controls, but there were no differences in antibody concentrations between the two groups after four and eleven months of the third dose. Additionally, there were no differences in cellular immune response between the two groups four months after the third dose.
