Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare severe clinical syndrome. HLH manifesting during pregnancy has been paid much attention in recent years. Despite the specificity of pregnancy-related HLH, there has not been any consensus regarding its treatment. According to a previous study, corticosteroid/IVIG is the mainstream therapy; however, the efficacy is controversial. Etoposide is an important agent in the HLH-94 regimen; nevertheless, its use is limited because of possible toxicity to the fetus.
Methods: In this study, we summarized 13 cases from 4 medical institutions from April 2011 to April 2018. Treatment regimens and outcomes were observed.
Results: The median age was 26 (20-36) years old. The median gestational age was 28 (10-35) weeks. In these 13 patients, 10 were treated with methylprednisolone/IVIG and was effective in only two patients. In 6 patients who used etoposide during their treatment, all achieved remission. The median time from onset of disease to use of etoposide was 36 (17-131) days. Five of these 6 patients were treated with corticosteroids with/without IVIG before etoposide. One patient with pulmonary tuberculosis and one with lymphoma were treated according to etiology and achieved long survival.
Conclusion: For treatment of pregnancy-related HLH, particularly for patients who do not respond to corticosteroids/IVIG therapy, etoposide should be used bravely. Nevertheless, suitable dosages and toxic and side-effects require further clinical observation.

Quantitative structure-property relationship (QSPR) modeling has emerged as a pivotal tool in the field of medicinal chemistry and drug design, offering a predictive framework for understanding the correlation between chemical structure and physicochemical properties. Topological indices are mathematical descriptors derived from the molecular graphs that capture structural features and connectivity, playing a crucial role in QSPR analysis by quantitatively relating chemical structures to their physicochemical properties and biological activities. Lung cancer is characterized by its aggressive nature and late-stage diagnosis, often limiting treatment options and significantly impacting patient survival rates.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and haemophagocytic lymphohistiocytosis (HLH) are rare but severe immune-mediated diseases with overlapping clinical manifestations. We present a case of a woman in her late 40s with rheumatoid arthritis who developed DRESS/HLH overlap syndrome after starting hydroxychloroquine and leflunomide therapy. Despite corticosteroid treatment, her condition worsened, necessitating etoposide therapy.

Encapsulated BV6 and SM164, two bivalent second mitochondria-derived activator of caspase (Smac) mimetics, in etoposide (ETO)-lipopolymer nanoparticles (NPs) have been developed to deplete inhibitor of apoptosis proteins (IAP), impair DNA, and produce antagonistic effects on glioblastoma multiforme (GBM) in nude mice. The NPs, composed of cocoa butter (CB) and polyvinyl alcohol (PVA), were stabilized by glycerol monostearate and Pluronic F-127, and grafted with transferrin (Tf) and wheat germ agglutinin (WGA) to dock the blood-brain barrier (BBB) and degenerated dopaminergic neurons. The dual-targeting NPs increased the BBB permeability of BV6, SM164 and ETO via recognizing Tf receptor (TfR) and N-acetylglucosamine that are abundantly expressed on brain microvascular endothelial cells.

During its catalytic cycle, the homodimeric ATPase topoisomerase II alpha (TOP2A) cleaves double stranded DNA and remains covalently bound to 5' ends via tyrosine phosphodiester bonds. After passing a second, intact duplex through, TOP2A rejoins the break and releases from the DNA. Thereby, TOP2A can relieve strain accumulated during transcription, replication and chromatin remodeling and disentangle sister chromatids for mitosis.

Electronic address:
The protective effects of mangiferin (MAG) against etoposide- and high glucose (HG)-induced DNA damage and aging were investigated in human bone marrow-mesenchymal stem cells (hBM-MSCs). Etoposide, a topoisomerase II inhibitor, was used to induce double-strand breaks (DSBs) in hBM-MSCs, resulting in increased genotoxicity, elevated levels of the DNA damage sensor ATM and CDKN1A, and decreased levels of the aging markers H3 and H4. MAG activated AMPK and SIRT1, thus protecting against DSB-induced damage.
