Antibody responses to influenza vaccine in patients on biological therapy: Results of RIER cohort study.
Influenza vaccine is recommended for patients with autoimmune inflammatory rheumatic diseases who receive biological therapy. To evaluate if biological therapy impairs immunization after seasonal influenza vaccine. ⋯ Among the patients on biological therapy vaccinated against influenza, anti-TNF therapy was identified as a predictive factor of final seropositivity. Rituximab presented a lower rate of final seropositivity, which could be increased with an accurate administration schedule.

Diabetes mellitus can affect the lungs, in its various structures and functions. Current research is being conducted to establish the clinical impact of hyperglycaemia on lung function. The objective of this study is to determine if the glycaemic state (euglycaemic, prediabetes or diabetes) is associated with a decrease in lung volume, determined by spirometry. ⋯ Subjects with diabetes have a lower %PEF than euglycaemic and prediabetic subjects, while the %FEV1, %FVC and the FEV1/FVC ratio do not vary between the different glycaemic states. Acute glycaemic non-control correlated with a decrease in more spirometric parameters than chronic glycaemic non-control.

Heart failure (HF) is a chronic disease with significant morbidity and mortality. Substantial haemodynamic changes such as hypoperfusion and intestinal congestion can alter the composition of the intestinal microbiota in patients with HF. The aim of this systematic review is to evaluate the influence of bowel function in patients with HF and the possible role of the intestinal microbiota in the development and evolution of the latter. ⋯ These studies seem to confirm that HF patients present with substantial abnormalities in the composition of their intestinal microbiota. Trimethylamine N-oxide is identified as a key mediator between the alterations in the intestinal microbiota and HF and correlates with worse prognosis in HF patients. In conclusion, patients with HF present with frequent abnormalities in the characteristics of their intestinal microbiota, which may play a role in the prognosis of the disease.
