Feeling severely affected by multiple sclerosis: what does this mean?

BACKGROUND: The situation for people feeling severely affected by Multiple Sclerosis (MS) remains largely unexamined and the term 'severe MS' is not clearly defined. AIM: Our study describes this sub-group of patients utilizing exclusively a subjective inclusion criterion to analyse their reasons for feeling severely affected and document their perceived unmet needs. DESIGN: A questionnaire with open- and closed-ended items addressing only patients feeling severely affected was sent out nationwide. Expanded Disability Status Score (EDSS) and subjectively severe affectedness were analysed for correlation. After dichotomizing both scores by a median split, the answers were allocated to these groups and tested for significant differences. SETTING/PARTICIPANTS: 1,110 questionnaires were analysed regarding the closed-ended questions while a subsample of 40% (n = 445) was analysed regarding the open-ended questions. Average age of participants was 51.87 years. Average time since diagnosis was 16.6 years. Main course of the disease was secondary progressive (35.5%). RESULTS: The most frequently mentioned reasons for feeling severely affected were lack of mobility (56.4%) and fatigue (27.4%). Significant percentages for unmet needs were seen in the categories of funding services (31.0%), better social integration (24.7%) and medical support (25.2%). A significant correlation was observed between EDSS and subjectively felt affectedness (p ≤ 0.01). Motor disorders explained differences in patient needs behind a higher EDSS score; higher severe affectedness referred to other issues like dependency and immobility. CONCLUSIONS: EDSS is insufficient for usage as the sole instrument for measuring severe affectedness as it does not take into account other potential reasons. Complex patient needs necessitate multi-professional care as offered by palliative medicine.

Physical and immunological barrier of human primary nasal epithelial cells from non-allergic and allergic donors.

The epithelial cell-derived cytokine milieu has been discussed as a "master switch" in the development of allergic disease. To understand the role of innate immune response in nasal epithelial cells during allergic inflammation, we created and established a fast and minimally invasive method to isolate and culture human nasal epithelial cells from clinically and immunologically well characterized patients. Human nasal epithelial cells from non-atopic volunteers and from allergic rhinitis patients were compared in respect to their growth, barrier integrity, pattern recognition, receptor expression, and immune responses to allergens and an array of pathogen-associated molecular patterns and inflammasome activators. Cells from nasal scrapings were clearly identified as nasal epithelial cells by staining of pan-Cytokeratin, Cytokeratin-14 and Tubulin. Additionally, Mucin 5AC staining revealed the presence of goblet cells, while staining of tight-junction protein Claudin-1, Occludin and ZO-1 showed the ability of the cells to form a tight barrier. Cells of atopic donors grew slower than cells of non-atopic donors. All nasal epithelial cells expressed TLR1-6 and 9, yet the expression of TLR-9 was lower in cells from allergic rhinitis (AR) donors. Additionally, epithelial cells from AR donors responded with a different TLR expression pattern to stimulation with TLR ligands. TLR-3 was the most potent modulator of cytokine and chemokine secretion in all human nasal epithelial cells (HNECs). The secretion of IL-1ß, CCL-5, IL-8, IL-18 and IL-33 was elevated in HNECs of AR donors as compared to cells of non-atopic donors. This was observed in the steady-state (IL-18, IL-33) as well as under stimulation with TLR ligands (IL-18, IL-33, CCL-5, IL-8), aqueous pollen extracts (IL-18, IL-33), or the inflammasome activator Nigericin (IL-1ß). In conclusion, nasal epithelial cells of AR donors show altered physical barrier responses in steady-state and in response to allergen stimulation. Cells of AR donors show increased expression of pro-inflammatory and IL-1 family cytokines at baseline and under stimulation, which could contribute to a micromilieu which is favorable for Th2.
