[Biological disease-modifying anti-rheumatic drugs for pregnant and lactating women or male partners].

Effective medical treatment of rheumatic diseases during pregnancy and lactation is important, but the evidence for use of biological disease-modifying anti-rheumatic drugs (bDMARDs) is sparse and recommendations conflicting, which we discuss in this review. While some tumour necrosis factor (TNF)-α inhibitors appear safe during pregnancy and lactation, the evidence for use of non-TNF-α inhibitors is still too sparse to exclude adverse pregnancy outcomes and harm to the lactating child. The limited evidence on paternal exposure indicates, that TNF-α inhibitors do not affect male fertility or harm offspring.

Antigen biochips verify and extend the scope of antibody detection in Lyme borreliosis.

The antibody response of serum IgM and IgG of patients with neuroborreliosis and erythema migrans of Lyme borreliosis (LB) was examined against a 41-kDa flagellar antigen and an 8-mer synthetic OspC8 peptide (VAESPKKP) derived from the C-terminus of outer surface protein C (OspC) from Borrelia garinii. We developed a streptavidin-modified biochip-based immunodiagnosis and compared it with conventional methods such as enzyme-linked immunosorbent assay (ELISA) and Western blot (WB). The diagnostic sensitivity of the coated biochips was demonstrated to be identical, and the results of conventional assays such as ELISA and WB were confirmed.
