Abstract
Multiple sclerosis (MS) is an autoimmune inflammatory illness that affects the central nervous system (CNS) when the body's immune system attacks its tissue. It is characterized by demyelination and varying degrees of axonal loss. This article has compiled various studies elaborating MS and other autoimmune diseases (ADs) co-occurrence. Several conditions that fall into this category, including type 1 diabetes (T1D), rheumatoid arthritis (RA), Guillain-Barre syndrome (GBS), myasthenia gravis (MG), and many others, are found in MS patients and their relatives, suggesting one or more common etiologic mechanisms, including genetic, environmental, and immunological factors, supporting the concept of a possible influence of poly-autoimmunity on MS and the rest of ADs, as well as providing a significant feature for early detection of the disease and also a potential treatment option by clinical neurologists.

Abstract
Abstract
Background
Multiple sclerosis is an immune-mediated disease which has been associated to a great variety of mechanisms that could influence its pathogenesis. Numerous reports in the medical literature suggest that Helicobacter pylori may be a mediator of the disease. However, it is unknown if there is any clear association between MS and HP.
Results
We studied 144 persons with multiple sclerosis prospectively enrolled in our hematopoietic stem cell transplantation program. In 144 persons, 14% patients were positive for IgG-HP whereas 86% were negative, 8.3% pwMS were IgM-HP positive while 91.6% pwMS were negative, 18% patients were positive and 82% negative for IgA-HP. Significantly lower concentrations of anti-HP IgG were found in RRMS in comparison with SPMS (− 28.5, 95% CI 4.3–52.7). While concentrations of anti-HP IgA were significantly lower in SPMS in comparison with RRMS (0.54, 95% CI 0.1–0.9). In a multivariate analysis, positivity rate of anti-HP IgG was found to be higher in SPMS patients (OR 4.7, 95% CI 1.1–19.6).
Conclusions
There was a negative correlation between the presence of anti-HP antibodies and MS. Further larger studies with specific laboratory testing methods are needed to discard or confirm the potential role of anti-HP antibodies as protective for MS.

Abstract
Helicobacter pylori (Hp) is a likely trigger of systemic sclerosis (SSc), but systemic antigen-specific antibody (Ab) responses in a well-defined cohort of SSc patients have not been thoroughly assessed. Line immunoassay and immunoblotting testing Abs against 15 Hp antigens were performed in 91 SSc patients and 59 demographically matched healthy controls (HCs). Results were validated in an independent cohort of 35 SSc patients. Anti-Hp positivity was detected in 67% SSc patients vs 76.3% HCs. Among anti-Hp (+) individuals, anti-p67-FSH was less frequent in SSc than HCs (p = 0.016), whereas reactivity to the remaining 14 Hp antigens did not differ between patients and HCs. Anti-p67 Abs were less frequent in diffuse cutaneous SSc (dcSSc) compared with HCs (p = 0.018). Anti-p57 and anti-p33 Ab levels were lower in SSc vs HCs (p = 0.007 and p = 0.035, respectively). Anti-p57 and anti-p33 Ab levels were lower in limited cutaneous SSc (lcSSc) (p = 0.010) and dcSSc (p = 0.024), respectively, compared with HCs. Anti-p50 and anti-p17 Ab titers tended to be higher in dcSSc than in lcSSc. Sera from the independent SSc cohort showed comparable results. Anti-VacA Abs were more frequent in pulmonary arterial hypertension (p = 0.042), and anti-p30 Abs were more frequent in calcinosis (p = 0.007), whereas anti-VacA Ab levels were higher in lung fibrosis (p = 0.02). In conclusion, anti-Hp Abs are neither more frequent nor elevated in SSc compared with healthy population, the only exception being the higher frequency and levels of anti-VacA Abs in pulmonary hypertension and lung fibrosis, respectively. These results suggest that Hp is unlikely to be involved in the development of SSc.

Abstract
OBJECTIVES The aim of this study was to assess the existence of polyautoimmunity in a Greek cohort of multiple sclerosis (MS), particularly multiple autoimmune syndrome (MAS), i.e., the presence of three or more distinct autoimmune disorders (ADs) in the same individual. METHODS Cross-sectional control study. RESULTS The overall prevalence of polyautoimmunity in 2140 MS patients (female to male ratio: 2.1:1) was 8.3% (vs 6.07% in 1580 matched control participants, P = 0.008) mainly due to differences in autoimmune thyroid disorders (AITD) and vitiligo. The prevalence of MAS was 1.0%. The most frequent diseases encountered in MS were organ-specific ADs. There was no statistical difference in the total rates of ADs between female and male MS patients. There were higher rates of AITD in women (P = 0.004) and higher rates of iritis (P = 0.039) and ankylosing spondylitis (P = 0.003) in men. MS was diagnosed in the same year with AD in 7.4% of patients with additional ADs, earlier than AD in 42.0% and later than AD in 50.6%. CONCLUSION Polyautoimmunity and particularly MAS occur more frequently in MS patients than in control participants indicating that MS may be part of a generalized susceptibility to autoimmunity. Therefore, polyautoimmunity may be implicated in the etiopathogenesis of MS-related ADs, with a potential impact on relative therapeutic strategies.

Abstract
In the last year, several diseases from outside of the gastrointestinal tract have been associated with Helicobacter pylori infection. Indeed, this bacterium produces a low-grade inflammatory state, induces molecular mimicry mechanisms, and interferes with the absorbance of nutrients and drugs possibly influencing the occurrence or the evolution of many diseases. In addition to its role in some hematologic conditions, such as immune thrombocytopenic purpura, idiopathic sideropenic anemia, and vitamin B12 deficiency, which were included in the current guidelines, several other conditions such as cardiovascular diseases, diabetes mellitus, hepatobiliary diseases, and neurologic disorders have also shown promising results.

Abstract
OBJECTIVE To determine the Helicobacter pylori infection status in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO) spectrum. METHODS H. pylori infection was certified by indirect immunofluorescence assay. Aquaporin-4 (AQP4) antibody was detected by cell-based assay. H. pylori seroprevalence was measured in 118 patients with NMO (n = 52), high-risk NMO (hrNMO, longitudinally extensive transverse myelitis, n = 17 and recurrent optic neuritis, n = 7), MS (n = 42) and healthy controls (n = 27). Logistic regression analysis was used to determine associations between H. pylori infection and NMO and MS. RESULTS H. pylori antibodies were present in 119 serum samples (82.1%, 119/145), with antibody positivity in 90.4% (47/52) of the patients with NMO, 95.8% (23/24) of the patients with hrNMO, 73.8% (31/42) of the patients with MS and 59.3% (16/27) of the controls. NMO spectrum patients had greater positivity for H. pylori than MS patients (p < 0.05) and controls (p < 0.05). The frequency of H. pylori seropositivity did not significantly differ between MS patients and controls (p = 0.726). H. pylori seropositivity was significantly higher in AQP4 antibody-positive patients (54/58, 93.1%; p = 0.038) than in AQP4 antibody-negative patients (48/60, 80%). Logistic regression analysis showed that H. pylori seropositivity was significantly associated with hrNMO [odds ratio (OR) = 9.311, p = 0.005] or hrNMO + NMO (OR = 6.350, p = 0.028). CONCLUSION H. pylori infection was present in most Chinese patients with NMO and hrNMO, and may be a risk factor for the NMO spectrum.
