Anti-AChR, MuSK, and LRP4 antibodies coexistence: A rare and distinct subtype of myasthenia gravis from Indian subcontinent

ConclusionWe present a detailed clinical and laboratory analysis of the patient. This case report will emphasize the importance of evaluating anti-MuSK and anti-LRP4 antibodies even in patients with anti-AChR antibodies.

Among the differential diagnoses that should be considered in acute respiratory failure (ARF) are infectious processes, autoimmune diseases, interstitial pulmonary fibrosis, and pulmonary neoplasia. Timely diagnosis of lung neoplasia is complicated in the early stages. An opportune diagnosis, as well as the specific treatment, decrease mortality. ARF occurs 1 in 500 pregnancies and is most common during the postpartum period. Among the specific etiologies that cause ARF during pregnancy that must be considered are: (1) preeclampsia; (2) embolism of amniotic fluid; (3) peripartum cardiomyopathy; and (4) trophoblastic emboli...

The expression of cytokine receptors has a crucial role in many cellular processes. Recent studies reported that changes of receptor expression could control the action of mediators on target cells. The initiation of different signaling pathways and, therefore, specific effects on cells, depends on certain components forming the cytokine-receptor complex. These mechanisms control the immune response and affect both the course of diseases (oncological, autoimmune, inflammatory) and the effectiveness of therapy. This review describes the potential of immune mediator receptors to regulate the efficiency of cytokine activity d...

Authors: Martins AP, Prado LGR, Lillo P, Mioshi E, Teixeira AL, de Souza LC Abstract OBJECTIVE:: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with prominent motor symptoms. Patients with ALS may also manifest frontal behavior symptoms and cognitive decline, including impairment in facial emotion recognition. The authors aimed to investigate whether deficits in emotion recognition were associated with frontal behavior symptoms in ALS. METHODS:: Participants were patients with probable or definite sporadic ALS (N=21; male:female ratio, 11:10; median age, 62 years; median disease duration, 3 ...

We conducted a pilot case-control study to assess associations between acute gastroenteritis (AGE) and water availability, use patterns, and quality. Case patients with AGE and non-AGE controls who presented for care to two Indian Health Service hospitals were recru...

Abstract Myasthenia gravis (MG) is a common disorder that affects the neuromuscular junction. It is caused by antibodies against acetylcholine receptor and muscle‐specific tyrosine kinase; however, some MG patients do not have antibodies against either of the proteins. Recent studies have revealed antibodies against agrin and its receptor LRP4—both critical for neuromuscular junction formation and maintenance—in MG patients from various populations. Results from experimental autoimmune MG animal models indicate that anti‐LRP4 antibodies are causal to MG. Clinical studies have begun to reveal the significanc...

AbstractVery few cases of patients with myasthenia gravis (MG) who later developed amyotrophic lateral sclerosis (ALS) have been described, although some studies showed that significantly more cases than expected have ALS associated with a prior diagnosis of autoimmune diseases. Our aim was to investigate whether the association of ALS and MG was higher than expected in a population-based study and to describe the clinical features characterizing these patients. In Emilia Romagna Region of Italy, a prospective registry has been collecting all incident ALS cases since 1.1.2009. For each patient, detailed clinical informatio...

Abstract: The Guillain–Barré syndrome (GBS) is one of the few neuropathies well known to the general public, in part because of its association with swine flu vaccinations in 1976. GBS has again reached the general public with its possible association with Zika virus. The virus, borne by infected Aedes aegypti mosquitos, is being linked to birth defects when pregnant women are bitten and infected. There are early reports also linking GBS to Zika infection, which could expose a wider range of infected people to the neuropathy. This summer infected Aedes mosquitos will likely reach southern portions of the Unite...

When evaluating a patient with progressive weakness for the first time, it is occasionally difficult to distinguish a motor neuron disease from an autoimmune neuromuscular disorder. Our neurological testing may even cloud the picture, as nearly 1/3 of patients with amyotrophic lateral sclerosis (ALS) may have decrement on repetitive nerve stimulation [1] and the risk of ALS is increased in people with concomitant autoimmune disease including myasthenia gravis (MG) [2]. In this context, the neurologist may wish to commence immunotherapy given the dismal alternative.

Abstract: In this issue, we review clinical features associated with an elevated serum creatine kinase level found in a percentage of patients with amyotrophic lateral sclerosis (ALS). The treatment of ALS remains problematic, and issues with offerings on the internet for unregulated stem cell treatment and the movement for right-to-try experimental drugs are discussed. The last What's in the Literature? discussed information about recording from stimulating electrodes implanted in the diaphragm of ALS patients, and this issue discusses the results of a randomized trial using diaphragm pacing. Chronic inflammatory demyelin...
