B cells are increasingly recognized as major players in multiple sclerosis pathogenesis. The BAFF/APRIL system is crucial for B cell homoeostasis and may drive B cell-dependent autoimmunity. We asked whether this system is affected by Interferon (IFN)-beta therapy. We analysed transcription of the ligands (BAFF, APRIL, TWE-PRIL) and the corresponding receptors (BAFF-R, TACI and BCMA) by TaqMan-PCR ex vivo in whole blood and in immune cell subsets purified from IFN-beta-treated multiple sclerosis patients. Serum BAFF concentrations were determined by ELISA. This cross-sectional study involved 107 donors. IFN-beta therapy strongly induced BAFF transcription proportionally to the IFN-beta biomarker MxA in monocytes and granulocytes in vivo. BAFF serum concentrations were elevated in IFN-beta-treated multiple sclerosis patients to a similar level as observed in SLE patients. In cultured PBMC, neutrophils, fibroblasts and astrocytes, BAFF was induced by IFN-beta concentrations similar to those reached in vivo in treated multiple sclerosis patients. BAFF turned out to be the main regulated element of the BAFF/APRIL system. In untreated multiple sclerosis patients, there was no BAFF increase as compared to healthy controls. Our study reveals a complex situation. We show that IFN-beta therapy induces a potent B cell survival factor, BAFF. However, B cell depletion would be desirable at least in some multiple sclerosis patients. The systemic induction of BAFF by IFN-beta therapy may facilitate the production of various autoantibodies and of IFN-neutralizing antibodies. Individual MS/NMO patients who have major B cell involvement may benefit less than others from IFN-beta therapy, thus explaining interindividual differences of the therapeutic response.

Background: Paraneoplastic neurological syndromes (PNS) are indirect remote effects of cancer on the nervous system, often associated with the presence of specific serum antibodies. The most recently described PNS defining reactivity is anti-Ma/anti-Ta. Here we present 22 newly diagnosed patients with anti-Ma or antiTa reactivity, refine the associated clinical picture and review all published patients to date. Patients and methods: Patients were identified by testing for PNMA1 and PNMA2 antibodies by western blotting and indirect immunofluorescence. Clinical data were obtained either by referral of the patient or from the referring physicians. Results: Analysis of 22 new patients (14 anti-Ma, eight anti-Ta) confirmed that anti-Ta are usually found in young men with limbic encephalitis and testicular germ cell tumours who stabilise neurologically with long term survival after tumour treatment. Patients with anti-Ma were of either sex, middle-aged, presented with a range of tumours and neurological symptoms and had a limited response to treatment. Furthermore, we expanded the range of associated clinical features: (1) the peripheral nervous system may be involved; (2) an overlap with antiHu is possible; and (3) testicular tumour manifestation can be extragonadal or detectable only at orchiectomy. Conclusion: Refining and expanding the range of antiMa/anti-Ta associated neurological presentations and tumours clearly demonstrated that the distinction between anti-Ma and anti-Ta associated PNS is of high clinical relevance.Paraneoplastic neurological syndromes (PNS) are indirect remote effects of cancer on the nervous system.

Depressive disorders have shown an increasing prevalence over the past decades. Growing evidence suggests that pregnancy and childbirth trigger depressive symptoms not only in women but likewise in men. This study estimates the prevalence of paternal perinatal depressiveness in a German community sample and explores its link to partnership satisfaction as well as birth-related concerns and concerns about the future. Data was gathered in a longitudinal study over the second and third trimester of their partner’s pregnancy up to 6 weeks postpartum. In a two-stage screening procedure, 102 expectant fathers were assessed for symptoms of depression, anxiety, and partnership satisfaction using the Edinburgh Postnatal depression Scale (EPDS), the State/Trait Anxiety Inventory, a self-constructed questionnaire for birth concerns and the Questionnaire of Partnership. The prevalence of elevated depressive symptoms among expectant fathers was 9.8 % prenatally and 7.8 % postnatally. Prenatal relationship quality, prenatal EPDS scores, and birth concerns were significantly associated with and explained 47 % of the variance in paternal postnatal depressive symptoms. The prevalence of paternal depressive symptoms is a significant concern. Our findings point out the need for implementing awareness and screening for depressiveness in fathers in clinical routine in Germany as well as the necessity of developing a screening instrument for paternal birth-related anxiety.

Background: Natalizumab is a new therapeutic option for relapsing-remitting multiple sclerosis. As with other antibody therapies, hypersensitivity reactions have been observed. In the Natalizumab Safety and Efficacy in Relapsing-RemittingMultipleSclerosis(AFFIRM)trial,infusion-related hypersensitivity reactions developed in 4% of patients, usually within 2 hours after starting the infusion.

Due to its chronic and fluctuating time course, multiple sclerosis (MS), thus far, has not been regarded as a focus of palliative care. However, sometimes we are confronted with severely affected MS patients, who suffer from complex medical, physical and psychosocial problems, which are not fully covered by the current health care services. We present two cases of severely affected MS patients we saw in our outpatient MS clinic, and who, we believe, are candidates for palliative care. The first patient, with primary chronic progressive (pcP) MS for many years (Expanded Disability Status Scale (EDSS): 8.0) presented with complex painful dysaesthesias and a depressive syndrome. He refused any treatment, and finally committed suicide with the help of a euthanasia group in Switzerland. The second patient was also severely affected by a secondary chronic progressive (scP) MS (EDSS: 9.0) and was finally admitted to our palliative care unit due to a complex pain syndrome associated with panic attacks and anxiety. She spent three weeks on the palliative care unit and her symptoms improved gradually after changing and optimising her pain medication. The patient was discharged with home care and is seen regularly on the palliative care unit. Additionally, as a first step, a questionnaire was sent to 53 German MS specialists regarding their general view on the needs for palliative care in MS. Our two cases and the results of the questionnaire demonstrated that MS patients and their caregivers are confronted with a variety of symptoms which are difficult to treat, and are a cause of great suffering for the patients, including ataxia, depression and fatigue. The data of the questionnaire also showed that neurologists usually do not deal with end-of-life care issues in MS.More research is needed to define the role of palliative care in MS and establish appropriate interventions to improve the quality of life in advanced stage MS patients and their relatives.
