Autoimmune diseases represent a diverse group of disorders that have generally of unknown etiology and poorly understood pathogenesis. They may be organ-specific or systemic, giving rise to overlapping syndromes; more than one autoimmune disease may occur in the same patient. Numerous case reports have documented that multiple sclerosis (MS) may be present concurrently with other autoimmune diseases, most commonly rheumatoid arthritis, autoimmune thyroid disease, type I diabetes mellitus and pernicious anemia. Case reports of disseminated encephalomyelitis (DEM) coincidental with other autoimmune diseases are rare. Many of systemic autoimmune diseases cause central nervous system (CNS) demyelination and are frequently then diagnosed as MS, whereas they often are instances of DEM, the result of vascular, granulomatous or postinfectious manifestations. We have reviewed 15 patients with autoimmune diseases and CNS demyelination in order to determine the nature of the demyelinating process.

Pernicious anemia is uncommon in Africa. The purpose of this report is to describe a case of pernicious anemia observed in Madagascar. The revealing manifestation was encephalomyelitis with combined medullar sclerosis that responded favorably to vitamin B12 replacement therapy. Clinical symptoms included paresthesia associated with allodynia of all four extremities and with tetrapyramidal syndrome, medullar ataxia and minor cognitive disturbances ongoing for 5 months. Hemogram testing revealed macrocytic anemia. Serum cobalamin level was low. Anti-intrinsic factor antibody was detected. Spinal cord magnetic resonance imaging showed diffuse high-signal intensity along the posterior spinal cord extending from C1 to C4. Vitamin B12 replacement therapy led to full regression of clinical signs after six weeks. Association of central nervous system involvement with macrocytic anemia suggests vitamin B12 deficiency and pernicious anemia should be suspected. This disease can be considered as a curable form of myelitis in Africa and Madagascar.

The glutamic acid decarboxylase 65-kilodalton isoform (GAD65) antibody is a biomarker of autoimmune central nervous system (CNS) disorders and, more commonly, nonneurological autoimmune diseases. Type 1 diabetes, autoimmune thyroid disease, and pernicious anemia are the most frequent GAD65 autoimmune associations. One or more of these disorders coexists in approximately 70% of patients with GAD65 neurological autoimmunity. Neurological phenotypes have CNS localization and include limbic encephalitis, epilepsy, cerebellar ataxia, and stiff-person syndrome (SPS), among others. Classic SPS is a disorder on the spectrum of CNS hyperexcitability which also includes phenotypes that are either more restricted (stiff-limb syndrome) or more widespread (progressive encephalomyelitis with rigidity and myoclonus). GAD65 antibody is not highly predictive of a paraneoplastic cause for neurological disorders, but diverse cancer types have been occasionally reported. For all phenotypes, responses to immunotherapy are variable (approximately 50% improve). GAD65 autoimmunity is important to recognize for both coexisting nonneurological autoimmune associations and potential immunotherapy-response. Muscle Nerve 56: 15-27, 2017.
