The study aimed at the question if astrocytes react with morphological or functional changes when a skeletal muscle is pathologically altered. In rats, a myositis was induced in the gastrocnemius-soleus muscle. After 12 days, the immunoreactivity (IR) for glial fibrillary acidic protein (GFAP), morphometric parameters, and fibroblast growth factor-2 (FGF-2) expression of astrocytes were quantitatively evaluated in the dorsal horn of the spinal segment L4. Following inflammation, the area density of GFAP-IR as well as the proportion of astrocytes expressing FGF-2 increased significantly while the degree of astrocyte arborisation decreased as shown by a shape factor. The density of cell nuclei was unchanged suggesting that no myositis-induced cell divisions occurred. The data indicate that spinal astrocytes may influence pain processes particularly by increased FGF-2 synthesis.

The rapidly growing field of cancer immunotherapy has led to the development of new treatments such as immune checkpoint inhibitors. These agents are monoclonal antibodies that enable tumor-reactive T cells to overcome regulatory mechanisms and produce effective antitumor responses. The use of immune checkpoint inhibitors is expected to progressively increase because they have shown promising therapeutic outcomes in multiple types of cancer and clinicians should be aware of their possible side-effects. We report a case of a man diagnosed with a non-microcytic lung carcinoma who started treatment with a combination of immune checkpoint inhibitors (Nivolumab and Ipilimumab). He subsequently developed binocular diplopia, fatigue, mild dyspnea and upper back pain resembling a myasthenia gravis presentation. Finally, a diagnosis of immune checkpoint inhibitor-related myositis and myocarditis was made. The detection of GFAP antibodies in CSF has unclear clinical and pathogenic significance and they may rather represent an epiphenomenon of the immune inflammation process.
