Breast cancer-associated metastasis is significantly increased in a model of autoimmune arthritis

Introduction  

Sites of chronic inflammation are often associated with the establishment and growth of various malignancies including breast cancer. A common inflammatory condition in humans is autoimmune arthritis (AA) that causes inflammation and deformity of the joints. Other systemic effects associated with arthritis include increased cellular infiltration and inflammation of the lungs. Several studies have reported statistically significant risk ratios between AA and breast cancer. Despite this knowledge, available for a decade, it has never been questioned if the site of chronic inflammation linked to AA creates a milieu that attracts tumor cells to home and grow in the inflamed bones and lungs which are frequent sites of breast cancer metastasis.

Endemic syphilis in Europe

Nonvenereal syphilis (endemic syphilis) has existed in Europe since the 16th century. Main characteristics of the disease are its presence for a longer time in a specific territory and its transmission regardless of age and sex, mainly extragenitally in unsanitary living conditions. Nonvenereal syphilis was described under different names in almost all regions of Europe. The primary genital chancre was absent, and lesions were most frequently found in the mouth and affected mostly children. The disease spread in rural areas with poor economic and hygienic conditions. The disease was eradicated in Europe in the 20th century, but it is still present in some rural regions of the Arabian Peninsula, Southwest Asia, and North Africa.     

NMR‐based lipoprotein analysis for patients with severe hypercholesterolemia undergoing lipoprotein apheresis or PCSK9‐inhibitor therapy (NAPALI‐Study)

Taking into account the discordance between low‐density lipoprotein cholesterol (LDL‐C) and LDL particle (LDL‐P) number, cardiovascular risk more closely correlates with LDL‐P in patients. The aim of our study was to evaluate the number of lipid particles in patients with severe hypercholesterolemia treated with different lipid‐lowering regimens. Four groups of patients differing with respect to lipid‐lowering therapy were recruited from hypercholesterolemic outpatients and lipoprotein apheresis (LA) facilities, and were treated with statins alone (group A), with statins and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors (PCSK9i) (group B), with statins and LA (group C), or with statins, PCSK9i, and LA (group D). Cholesterol, triglycerides, LDL‐C, high‐density lipoprotein cholesterol (HDL‐C), LDL‐P number and size, HDL‐P number and size were determined using nuclear magnetic resonance spectroscopy. The lowest LDL‐P number was achieved at the end of LA sessions in combination with statins or in combination with statins and a monoclonal PCSK9i (median; 25th and 75th percentile) (group C: 244 nmoL/L: 237, 244, P < 0.05; group D: 244 nmoL/L: 99, 307, P < 0.05). Comparing LDL‐P number at the start of LA (group C: 978 nmoL/L: 728, 1404; group D: 954 nmoL/L: 677, 1521) to the other patient groups (groups A and B), the lowest LDL‐P number was measured in patients treated with PCSK9i and a statin (group B): LDL‐P (762 nmoL/L: 604, 1043, P < 0.05), large LDL‐P (472 nmoL/L: 296, 574, P < 0.05), and small LDL‐P (342 nmoL/L: 152, 494, P < 0.05). Very low‐density lipoprotein and HDL particle sizes remained approximately the same in all groups. LA in combination with statins or in combination with statins and PCSK9i most reduced LDL‐P numbers in hypercholesterolemic patients.
