Anti-citrullinated protein antibodies (ACPA) predict increased disease activity and disability in patients with inflammatory arthritis such as rheumatoid arthritis. However, the absence of these antibodies does not confer universally good prognosis. Recently, a new set of antibodies, anti-carbamylated (anti-CarP) antibodies, have been identified in patients with rheumatoid arthritis. This study aimed to investigate the association between anti-CarP antibodies, disability, and disease activity in these patients. ⋯ Arthritis Research UK.

In Bihar state, India, the cure rate of antimonial compounds (eg, sodium stibogluconate) in the treatment of visceral leishmaniasis (VL) has fallen from more than 85% to less than 50%. This reduction has been attributed to long-term, widespread misuse of antimonial drugs within the Indian private health-care system. We aimed to test the hypothesis that exposure to arsenic in drinking water in this region has resulted in antimony-resistant Leishmania parasites. ⋯ Wellcome Trust.

Cardiovascular risk is increased in the anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV). CD4+CD28- T cells are expanded in patients with AAV who are seropositive for cytomegalovirus (CMV), and are associated with increased mortality. CMV seropositivity in other conditions is associated with arterial stiffness, a marker of cardiovascular risk. We assessed whether CD4+CD28- T cells in CMV seropositive patients with AAV are associated with arterial stiffness and whether treatment with valaciclovir reduces this cell population. ⋯ Wellcome Trust, Vasculitis UK.

Somatic activating mutations in PIK3CA, which encodes the p110α catalytic subunit of phosphoinositide-3-kinase (PI3K) are frequently found in cancers and have been identified in a spectrum of mosaic overgrowth disorders ranging from isolated digit enlargement to more extensive overgrowth of the body, brain, or vasculature. We aimed to study affected dermal fibroblasts with a view to inform therapeutic studies, and to observe cancer-associated mutations in isolation. ⋯ Wellcome Trust, Sackler Fund, National Instititute for Health Research.

Heart failure is a complex clinical syndrome that occurs at the end stage of heart disease. Despite advances in therapy for heart failure, improvement of clinical outcomes remains a challenge for physicians. The identification of treatment response early in the course of disease would be useful to improve management of these patients. The aim of this study was to identify novel biomarkers in plasma that could predict treatment response in patients with heart failure. ⋯ European Union's Seventh Framework Programme (BIOSTAT-CHF), John and Lucille van Geest Foundation.
