A patients Because of the past 3 decades’ extensive research, several disease modifying therapies became available, thus a paradigm change is multiple sclerosis care was necessary. In 2018 a therapeutic guideline was created recommending that treatment of persons with multiple sclerosis should take place in specified care units where the entire spectrum of disease modifying therapies is available, patient monitoring is ensured, and therapy side effects are detected and treated promptly. In 2019 multiple sclerosis care unit criteria were developed, emphasizing personnel and instrumental requirements to provide most professional care. However, no survey was conducted assessing the real-world adaptation of these criteria. Objective To assess whether Hungarian care units fulfil international criteria. Methods A self-report questionnaire was assembled based on international guidelines and sent to Hungarian care units focusing on 3 main aspects: personnel and instrumental background, disease-modifying therapy use, number of people living with multiple sclerosis receiving care in care units. Data on number of persons with multiple sclerosis were compared to Hungarian prevalence estimates. Descriptive statistics were used to analyse data. Results Out of 27 respondent care units, 3 fulfilled minimum requirements and 7 fulfilled minimum and recommended requirements. The least prevalent neighbouring specialties were spasticity and pain specialist, and neuro-ophthalmologist and oto-neurologist. Only 15 centres used all available disease modifying therapies. A total number of 7213 people with multiple sclerosis received care in 27 respondent centres. Compared to prevalence estimates, 2500 persons with multiple sclerosis did not receive multiple sclerosis specific care in Hungary. Conclusion Less than half of Hungarian care units provided sufficient care for people living with multiple sclerosis. Care units employing fewer neighbouring specialties, might have difficulties diagnosing and providing appropriate care for persons with multiple sclerosis, especially for people with progressive disease course, contributing to the reported low number of persons living with multiple sclerosis.

Neuromyelitis optica (NMO) is an autoimmune demyelinating inflammatory disorder, mediated by pathogenic autoantibodies against aquaporin 4 (AQP4), the main water channel of the central nervous system (CNS). NMO is characterized by local IgG deposition and complement activation within the CNS, but the three complement pathways have not been systematically investigated.We evaluated the overall activation of the classical, alternative, and MBL-lectin pathways in the peripheral blood of 25 patients with AQP4-seropositive NMO spectrum during remission and 113 healthy controls by three ways: (1) we measured the concentrations of native complement proteins of the three pathways [C1-inhibitor (C1-inh), C1q, C4, C3, C5, factor I, factor B, properdin]; (2) the concentrations of complement products suggesting in vivo activation (C1rC1sC1-inh, C3a, C3bBbP, and SC5b-9); and (3) the total activity of the three complement pathways. Additionally we measured levels of C1rC1sC1-inh, C3a, C3bBbP in cerebrospinal fluid (CSF) of 6 patients with relapsing NMO and of 18 patients with relapsing multiple sclerosis (MS).The serological studies indicated that total complement activity of the classical [median (interquartile range) 72 (61-82) vs. 65 (56-73) CH50/mL; p = 0.0122] and of the lectin pathways [73 (59-111) vs. 49 (3-92)%; p = 0.0078)] were elevated compared with the controls, whereas that of the alternative pathway was not significantly different. The levels of C3 [1.1 (0.9-1.3) vs. 1.4(1.2-1.5) g/L; p <0.00011, factor B [89 (77-115) vs. 103 (93-113)%; p = 0.0397] and factor I [85 (69-95) vs. 101 (93-107)%; p = 0.00071, as well as of properdin [92 (74-104) vs. 108 (97-122)%; p = 0.0028] were significantly lower in the patients than in the controls. The only increase in the patients was ascertained in the relative concentration of C1rC1sC1-inh vs. the C1-inhibitor (42.3 [31.9-65.0] vs. 30.8 [13.5-43.5] AU/mg; p = 0.0007). The absolute and relative levels of the other complement activation products were not elevated in the patients. On the contrary, the serum concentrations of C3a, C3bBbP, and SC5b-9 of the patients were lower than those of the controls. The absolute concentration of the complement activation products (C1rC1sC1-inh, C3bBbP, C3a) and the ratio of C3bBbP/C1rC1sC1-inh did not differ in NMO and MS CSF samples. The ratio of C3bBbP/C1rC15C1-inh was similar in NMO plasma and CSF samples. We found a higher ratio of C3bBbP/C1rC1sC1-inh in the plasma of control subjects compared to those in any pathological samples.Our results do not indicate substantial systemic complement activation if NMO activity is adequately controlled; nevertheless, the complement system is abnormally affected even during remission. The relative ancillarity of the alternative compared to the classical pathway may also suggest that suppression of the alternative pathway by treatment may be important to achieve remission.

In the majority of cases, anti-NMDA (N-methyl-D-aspartate) receptor encephalitis is a severe, but treatable disorder, therefore early diagnosis and adequate therapy are very important. It should be suspected in children and young women, who develop acute psychiatric symptoms and seizures. During the course of the disease severe encephalopathy, agitation, hallucinations, orofacial dyskinesias, prolonged cognitive disturbance, autonomic symptoms can be observed and akinetic mutism develops. EEG shows diffuse slowing. Brain MRI is normal or unspecific. Elevated protein, pleiocytosis and oligoclonal bands can be present in the CSF. Detection of NMDA-receptor antibodies in sera or CSF confirms diagnosis.We present the case of a 15-year old girl, who fully recovered within two months after steroid treatment and repeated plasma exchange. Ovarian teratoma has not been detected.

Intravascular lymphomatosis is a rare systemic disease characterized by proliferation of malignant B or rarely T lymphocytes. Skin and the brain are predominantly affected. We describe a patient presenting with focal neurological signs and progressive dementia. Cerebral neuroimaging findings were nonspecific. Postmortem examination revealed intravascular proliferation of atypical mononuclear cells in the lumens of small vessels in all organs. The authors conclude that diagnosis requires a high index of suspicion and pathological examination of the affected organs, but is rarely made ante mortem.
