Extrahepatic manifestations linked to hepatitis B Virus (HBV) are usually indirect consequences of immune-mediated mechanisms triggered by the virus replication. Strong evidence of brain HBV replication is missing and direct involvement of HBV in nervous system symptoms has been rarely reported. We report two cases of neurological manifestations contemporary to HBV infection. In both cases, HBV-DNA and HBsAg could be quantified in the cerebrospinal fluid (CSF) at relatively high levels. Differential quantification of HBsAg and HBV viral load both in CSF and in blood as well as phylogenic studies on HBV genomic sequences obtained from blood and CSF provided strong arguments for central nervous system viral replication in both cases...

BACKGROUND: In recent years the treatment of many tumor entities has been revolutionized by the use of modern immunotherapies with checkpoint inhibitors; however, good response rates are contrasted by many immune-mediated side effects. Neurological immune-mediated side effects are rare but often severe complications of checkpoint inhibitor treatment. METHOD: A systematic search in the PubMed and Web of Sciences databases was carried out for case reports and studies on neurological side effects during checkpoint inhibitor treatment...

Guillain-Barré syndrome (GBS) belongs to the group of peripheral immune-mediated neuropathies often preceded by an inflammatory episode. GBS is rarely associated with hepatitis A virus (HAV) infection, the latter as a rule antecedent of the neurological disorders. This association is quite rare in childhood, and so far, only isolated cases have been described. We report an unusual case of pediatric GBS which development coincided with the development of HAV IgM (+) viral hepatitis A. From the second to the 14th day after admission to the hospital for mild jaundice of the skin and sclera in a 12-yr-old boy, the following neurological disorders have developed: absent Achilles and knee-jerk reflexes, diminished brachioradialis reflex, moderately decreased muscle power in the upper extremities and more pronounced power loss in the lower extremities...

We report a 2-year-old boy who was evaluated for difficult waking during prolonged intensive care unit admission associated with bone marrow transplant for Wiskott-Aldrich syndrome. Neurologic examination was found to be abnormal, with nuchal rigidity initially, then decreased extremity movement and areflexia developing over several days. Electromyogram showed length-dependent, axonal, sensorimotor polyneuropathy. Cerebrospinal fluid showed albuminocytologic dissociation suggestive of Guillain-Barre syndrome or acute motor and sensory axonal neuropathy variant...

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is probably the best recognized progressive immune-mediated peripheral neuropathy. It is characterized by a symmetrical, motor-predominant peripheral neuropathy that produces both distal and proximal weakness. Large-fiber abnormalities (weakness and ataxia) predominate, whereas small-fiber abnormalities (autonomic and pain) are less common. The pathophysiology of CIDP is inflammatory demyelination that manifests as slowed conduction velocities, temporal dispersion, and conduction block on nerve conduction studies and as segmental demyelination, onion-bulb formation, and endoneurial inflammatory infiltrates on nerve biopsies...

The efficacy of intravenous immunoglobulins (IVIg) in patients with autoimmune diseases (AID) has been known for several decades. Majority of these patients received IVIg in hospital. A retrospective study was conducted in 22 centers in France to evaluate the feasibility of the administration of Tegeline, an IVIg from LFB Biomedicaments, and assess its safety at home, compared to in hospital, in patients with AID. The included patients were at least 18 years old, suffering from AID, and treated with at least 1 cycle of Tegeline at home after receiving 3 consecutive cycles of hospital-based treatment with Tegeline at a dose between 1 and 2 g/kg/cycle...

Macrophages are critical mediators of the innate immune response against foreign pathogens, including bacteria, physical stress, and injury. Therefore, these cells play a key role in the "inflammatory pathway" which in turn can lead to an array of diseases and disorders such as autoimmune neuropathies and myocarditis, inflammatory bowel disease, atherosclerosis, sepsis, arthritis, diabetes, and angiogenesis. Recently, more studies have focused on the macrophages inflammatory diseases since the discovery of the two subtypes of macrophages, which are differentiated on the basis of their phenotype and distinct gene expression pattern...

Guillain Barré Syndrome (GBS) is one of the commonest acquired immune-mediated neuropathies, often preceded by infections. Although cellular immune responses are shown to substantially account for the pathophysiology of GBS, the precise mechanistic basis of risk and disease course remains enigmatic till date. Cytokines are best known for their abilities to drive cellular immunity and inflammation through their co-ordinated actions. Data obtained from clinical and animal model studies suggest important implications of some of the cytokines in the progression and recovery of GBS...

Objective: Type 1 diabetes mellitus (T1DM) is a chronic immune-mediated disease. Diabetic peripheral neuropathy (DPN) is an important microvascular complication of T1DM. One of the most important risk factors for the development of DPN is poor glycemic control. We evaluated the prevalence of DPN among T1DM patients and determined the association between DPN and glycated hemoglobin (HbA1c) level. Materials & Methods: The subjects were recruited prospectively upon initial evaluation at Imam Reza Hospital, Mashhad, Iran from Jan 2013 to Jan 2015...

INTRODUCTION: Numb chin syndrome (NCS) or mental neuropathy (MN) is a disorder characterized by sensory neuropathy on the distribution of the inferior alveolar nerve or mental nerve. The most frequent causes are of odontogenic origin (infections, wrong therapies). Other etiologies are related to primary tumor, metastasis, osteoradionecrosis and medication-related osteonecrosis of the jaw (MRONJ). The aim of this study is to highlight the clinical importance of NCS as one of the first symptoms of cancer or as consequence of drug therapy...

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcription factors. They exist in three isoforms (PPAR-α, PPAR-β/δ, and PPAR-Υ) in humans, but mainly PPAR-Υ, and they are expressed in retinal epithelial pigment. PPARs are involved in mediating numerous pathological implications in eye such as diabetic retinopathy (DR), choroidal neovascularization (CNV), glaucoma, diabetic macular edema, and other retinal diseases. Peroxisome proliferator-activated receptors are key players in various biological pathways like lipid degeneration, immune regulation, and reactive oxygen species regulation, regulation of vascular endothelial growth factor, matrixmetalloproteinase-9, and docosahexaenoic acid pathway...

Chronic inflammatory demyelinating polyneuropathy is an acquired, presumably immune-mediated peripheral neuropathy, characterized by symmetric sensory-motor involvement. Although most often idiopathic, it has been described in association with several disorders, sometimes improving under treatment. We present the case of a 57-year-old male who was admitted to hospital for paresthesias and muscle weakness affecting both upper limbs, initially only the hands, but with worsening and ascending progression during the last three years...

OBJECTIVE: Chronic inflammation in HIV-infected individuals drives disease progression and the development of comorbidities, despite viral suppression with combined antiretroviral therapy. Here, we sought evidence that vagal dysfunction, which occurs commonly as part of HIV-associated autonomic neuropathy, could exacerbate inflammation through gastrointestinal dysmotility, small intestinal bacterial overgrowth (SIBO), and alterations in patterns of soluble immune mediators. DESIGN: This is a cross-sectional observational study...

Despite the well-recognized importance of immunoglobulin therapy individualization during the treatment of chronic inflammatory demyelinating polyneuropathy (CIDP), the pathway to best achieve optimization is unknown. There are many pharmacokinetic and immunobiologic variables that can potentially influence the appropriateness of any individual therapy. Although identification of specific autoantibodies and their targets has only been accomplished in a minority of patients with CIDP, already the diagnostic and treatment implications of specific autoantibody detection are being realized...

BACKGROUND: Pericytes are multipotent cells present in every vascularized tissue in the body. Despite the fact that they are well-known for more than a century, pericytes are still representing cells with intriguing properties. This is mainly because of their heterogeneity in terms of definition, tissue distribution, origin, phenotype and multi-functional properties. The body of knowledge illustrates importance of pericytes in the regulation of homeostatic and healing processes in the body...
