Here we report a case of pediatric multiple sclerosis treated with interferon beta-1b. Interferon beta is widely used in adult patients with multiple sclerosis (MS). However, its effects and safety in pediatric patients have not been well established. Although supporting data are limited, the use of disease modifying therapies (DMTs) such as interferon beta-1b is recommended early in treatment of children with MS. Reports of interferon beta treatment in pediatric MS patients in Korea are rare. In this report, we describe a Korean girl who was effectively treated with interferon beta-1b for three years. There were no relapses or serious side effects. Therefore, this report provides evidence supporting the use of interferon beta in pediatric MS patients in Korea and other Asian countries. We also reviewed current medical treatment of MS, including some DMTs and second-line treatment options such as natalizumab and cyclophosphamide, and several new oral agents such as fingolimod.

Preliminary studies have evaluated the effects of interferon beta formulations in the treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) because of pathogenic similarities between CIDP and multiple sclerosis (MS). However, the efficacy of Interferon, which has been widely used for relapsing-remitting MS, is controversial in CIDP. We report here a 31year old woman with relapsing-remitting type MS treated with IFN beta-1b over 2 years who developed overt CIDP. She responded favorably to steroids. This case suggests that IFN beta-1b treatment may not prevent development of CIDP.

Sjogren's syndrome is a slowly progressive autoimmune disorder that predominantly affects major exocrine glands, and may also involve the central nervous system (CNS). It is sometimes very difficult to differentiate the CNS Sjogren's syndrome from multiple sclerosis. Here, we report two cases of Sjogren's syndrome who developed variable neurological symptoms mimicking the relapsing-remitting form of multiple sclerosis. There had been several relapses during the course of interferon-beta treatment but no relapses have occurred after steroid maintenance therapy.

The development of microarray technology has facilitated the understanding of gene expression profiles. Despite its convenience, the cause of dye-bias that confounds data interpretation in dual-color DNA microarray experiments is not well known. In order to economize time and money, it is necessary to identify the cause of dye bias, since designing dye-swaps to reduce the dye-specific bias tends to be very expensive. Hence, we sought to determine the reliable cause of systematic dye bias after treating murine macrophage RAW 264.7 cells with 2-keto-3-deoxyoctonate (KDO), interferon-beta (IFN-beta), and 8-bromoadenosine (8-BR). To find the cause of systematic dye bias from the point of view of fluorescence quenching, we examined the correlation between systematic dye bias and the proportion of each nucleotide in mRNA and oligonucleotide probe sequence. Cy3-dye bias was highly correlated with the proportion of adenines. Our results support the fact that systematic dye bias is affected by fluorescence quenching of each feature. In addition, we also found that the strength of fluorescence quenching is based on not only dye-dye interactions but also dye-nucleotide interactions as well.

Local cutaneous reactions have been reported at injection sites of interferon therapy, but these are usually erythema or rarely induration. Skin necrosis at the injection site is rare. We describe here a patient with multiple sclerosis who presented with cutaneous necrosis at the injection sites of interferon-β. Biopsy of the necrotic lesion showed dermal vessel thrombosis and complete ischemic coagulative necrosis of epidermis and dermis.

The study was aimed to investigate the synergistically effect of interferon-α (IFN-α) and homoharringtonine (HHT) on the proliferation, apoptosis, cell cycle of K562 cells and the expression of &beta;-catenin. The proliferation, apoptosis, cell cycle and &beta;-catenin mRNA expression of K562 cells treated with IFN-α and/or HHT were assayed with MTT, flow cytometry or RT-PCR respectively. The results showed that HHT alone, but not IFN-α alone, displayed a proliferation inhibition, apoptosis induction, G(0)/G(1) phase block and down-regulation of &beta;-catenin expression in K562 cells with concentration- and time-dependent manners. The expression level of &beta;-catenin mRNA after being treated with HHT was 0.5576 ± 0.0373, which were lower than that in control group (0.9369 ± 0.0142). The down-regulation of &beta;-catenin expression in group of IFN-α combined with HHT was higher significantly than that in HHT group (0.3737 ± 0.0529 vs 0.5576 ± 0.0373, P < 0.05). Otherwise, HHT combined with IFN-α did not demonstrate obvious toxicologic effect on bone marrow mononuclear cells. It is concluded that IFN-α combined with HHT can enhance the cytotoxic effect of HHT on K562 cells, which may be associated with down-regulation of &beta;-catenin expression.
