Ocular myasthenia gravis in a patient with euthyroid Graves' disease

Graves' disease (GD) and ocular myasthenia gravis (OMG) are autoimmune disorders which may occur in the same patient. Myasthenia gravis is 50 times more common in patients with Graves' disease when compared to the normal population. Typically, a patient may be diagnosed with one disorder and have no signs or symptoms of the other, including negative laboratory studies. Therefore, when managing patients with known Graves' disease, it is important to be alert to the possibility of ocular myasthenia.     

Unusual clustering of diseases in a Canadian Old Colony (Chortitza) Mennonite kindred and community.

We investigated a large Old Colony (Chortitza) Mennonite kindred with branches across Canada. Six generations of the kindred were traced. There was intermarriage among numerous family members. Insulin-dependent diabetes mellitus (IDDM) was identified in 10 members; all 7 living patients were found to carry the immunogenetic marker HLA-DR4. Nine other close relatives had disorders of carbohydrate metabolism, including gestational diabetes mellitus and non-insulin-dependent diabetes mellitus progressing to insulin use. Ten other relatives had autoimmune diseases, including rheumatoid arthritis, hyperthyroidism, hypothyroidism and multiple sclerosis. Cases of Alport''s syndrome, congenital malformations, inborn errors of metabolism and unusual malignant diseases were also found in the kindred. In the small Alberta community in which the kindred was ascertained there were people of Old Colony Mennonite descent with genetic conditions such as Gilles de la Tourette''s syndrome and congenital malformations, including congenital heart disease. This kindred represents the largest reported familial aggregation of IDDM. This disease and other disorders of carbohydrate metabolism occur in the context of a strong familial predisposition to autoimmune disease. Study of this family may permit empiric testing of proposed models of inheritance of diseases of complex origin such as IDDM. We report this Old Colony (Chortitza) Mennonite community because it is one of the settlements populated by this religious and genetic isolate, which extends across Canada and Central and South America and affords opportunities for the study of both common and rare inherited diseases.     

斜角肌间臂丛阻滞影响心率变异性的危险因素分析

摘要 目的：本研究旨在探讨斜角肌间臂丛阻滞影响心率变异性的危险因素及Logistic回归分析。方法：选取2021年5月至2022年3月于我院接受肩关节开放手术治疗的患者60例作为研究对象,按照麻醉方式不同随机分为实验组和对照组2组,其中实验组患者给与超声引导下斜角肌间臂丛神经阻滞,对照组患者进行单纯斜角肌间臂丛神经阻滞,统计患者的一般临床资料,对比分析阻滞前后心率变异指标、SpO₂、心率和平均动脉压水平;同时研究危险因素与心率变异性之间的关系。结果：斜角肌间臂丛阻滞影响心率变异性的单因素分析显示,危险因素与性别、平均年龄、BMI、总胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白、合并慢性病（糖尿病、高血压）、吸烟史和饮酒史无关（P>0.05）,镇痛维持时间较短、运动恢复时间较长、阻断节数较少的斜角肌间臂丛阻滞患者更易表现出心率变异性（P<0.05）。阻滞后,实验组LF、HF、LF/HF、RMSSD、SDNN和PNN50 %显著低于对照组（P<0.05）,而阻滞后SpO₂、心率和平均动脉压比较无差异（P>0.05）。影响心率变异性危险因素的多因素为镇痛维持时间（OR=6.224,P=0.001<0.05）、运动恢复时间（OR=9.556,P=0.002<0.05）、阻断节数（OR=7.591,P=0.001<0.05）。结论：斜角肌间臂丛阻滞出现心率变异性与镇痛维持时间、运动恢复时间、阻断节数有关。     

Relative risk of myelodysplastic syndromes in patients with autoimmune disorders in the General Practice Research Database

Background: Certain immunosuppressant drugs are known to increase the risk of myeloid neoplasms although it is unclear if underlying autoimmune disorder itself increases the risk of myeloid neoplasms. Methods: Using a nested case-control study in the General Practice Research Database (GPRD), we estimated the relative risk of myeloid neoplasms, specifically myelodysplastic syndromes (MDS) in patients with autoimmune disorders compared with patients without autoimmune disorders. Results: We identified 849 cases of MDS and 3417 matched controls. There was a slightly increased risk of MDS in patients with any autoimmune disorder (adjusted OR 1.5, 95% CI 1.1, 2.0), which was limited to patients diagnosed over 10 years prior to the index date (adjusted OR 2.1, 95% CI 1.4, 3.2). The elevated odds ratios of MDS were present in both untreated patients and patients who had a record of receiving multiple treatments. Conclusion: There was a modestly increased risk of MDS was in patients with a history of autoimmune disorder. However, it is difficult to determine whether autoimmune disorders increased the risk of MDS, or whether the small elevation in the risk estimate was an artifact of misdiagnosis resulting from early MDS symptoms similar to those of autoimmune disorders. Impact: These findings may indicate the increased need for MDS screening in patients with autoimmune disease, and further research regarding MDS etiology.     

The Increased Risk for Autoimmune Diseases in Patients with Eating Disorders

Objective

Research suggests autoimmune processes to be involved in psychiatric disorders. We aimed to address the prevalence and incidence of autoimmune diseases in a large Finnish patient cohort with anorexia nervosa, bulimia nervosa, and binge eating disorder.

Methods

Patients (N = 2342) treated at the Eating Disorder Unit of Helsinki University Central Hospital between 1995 and 2010 were compared with general population controls (N = 9368) matched for age, sex, and place of residence. Data of 30 autoimmune diseases from the Hospital Discharge Register from 1969 to 2010 were analyzed using conditional and Poisson regression models.

Results

Of patients, 8.9% vs. 5.4% of control individuals had been diagnosed with one or more autoimmune disease (OR 1.7, 95% CI 1.5–2.0, P<0.001). The increase in endocrinological diseases (OR 2.4, 95% CI 1.8–3.2, P<0.001) was explained by type 1 diabetes, whereas Crohn''s disease contributed most to the risk of gastroenterological diseases (OR 1.8, 95% CI 1.4–2.5, P<0.001). Higher prevalence of autoimmune diseases among patients with eating disorders was not exclusively due to endocrinological and gastroenterological diseases; when the two categories were excluded, the increase in prevalence was seen in the patients both before the onset of the eating disorder treatment (OR 1.5, 95% CI 1.1–2.1, P = 0.02) and at the end of the follow-up (OR 1.4, 95% CI 1.1–1.8, P = 0.01).

Conclusions

We observed an association between eating disorders and several autoimmune diseases with different genetic backgrounds. Our findings support the link between immune-mediated mechanisms and development of eating disorders. Future studies are needed to further explore the risk of autoimmune diseases and immunological mechanisms in individuals with eating disorders and their family members.     

Autoantibodies against serotoninergic 5-HT(4) receptor in patients with heart failure

Serotoninergic 5-HT(4) receptors have been detected in several tissues including the heart. An autoimmune mechanism may underline the pathogenesis of heart failure. The aim of this work was to look for autoantibodies to the 5-HT(4) receptor in patients with heart failure. We looked for the presence of autoantibodies against 5-HT(4) receptor as well as angiotensin II type (AT1), β(1)-adrenoceptor, and muscarinic M2 receptors in the sera of 176 patients with heart failure (female: n=96, male: n=80) and in 108 controls (female: n=69; male: n=39). The prevalence of 5-HT(4) receptor autoantibodies was 18.8% (n=33) in the group of patients with heart failure and 4.6% (n=5) in the control group (p<0.002). The prevalence of autoantibodies against AT1 was 1.7 (n=3), β(1)-adrenoreceptor 0.6 (n=1), and muscarinic-receptor M2 4.2 (n=5). Female patients with diabetes and heart failure had a positive trend (p=0.07) to the presence of 5-HT(4) receptor autoantibodies. In the group of female heart failure patients we found a significant correlation with the presence of coronary heart disease (p=0.05). The clinical relevance of 5-HT(4) receptor autoantibodies has to be further studied. The prevalence of 5-HT(4) receptor autoantibodies was highly significant in patients with chronic heart failure. It was also a significant correlation between these autoantibodies and the female subgroup with coronary heart disease. It is conceivable that the increased prevalence of autoantibodies against the 5-HT(4) receptor in patients with heart failure is more than just an epiphenomenon.     

Burden of Depressive Disorders by Country,Sex, Age,and Year: Findings from the Global Burden of Disease Study 2010

Background

Depressive disorders were a leading cause of burden in the Global Burden of Disease (GBD) 1990 and 2000 studies. Here, we analyze the burden of depressive disorders in GBD 2010 and present severity proportions, burden by country, region, age, sex, and year, as well as burden of depressive disorders as a risk factor for suicide and ischemic heart disease.

Methods and Findings

Burden was calculated for major depressive disorder (MDD) and dysthymia. A systematic review of epidemiological data was conducted. The data were pooled using a Bayesian meta-regression. Disability weights from population survey data quantified the severity of health loss from depressive disorders. These weights were used to calculate years lived with disability (YLDs) and disability adjusted life years (DALYs). Separate DALYs were estimated for suicide and ischemic heart disease attributable to depressive disorders.Depressive disorders were the second leading cause of YLDs in 2010. MDD accounted for 8.2% (5.9%–10.8%) of global YLDs and dysthymia for 1.4% (0.9%–2.0%). Depressive disorders were a leading cause of DALYs even though no mortality was attributed to them as the underlying cause. MDD accounted for 2.5% (1.9%–3.2%) of global DALYs and dysthymia for 0.5% (0.3%–0.6%). There was more regional variation in burden for MDD than for dysthymia; with higher estimates in females, and adults of working age. Whilst burden increased by 37.5% between 1990 and 2010, this was due to population growth and ageing. MDD explained 16 million suicide DALYs and almost 4 million ischemic heart disease DALYs. This attributable burden would increase the overall burden of depressive disorders from 3.0% (2.2%–3.8%) to 3.8% (3.0%–4.7%) of global DALYs.

Conclusions

GBD 2010 identified depressive disorders as a leading cause of burden. MDD was also a contributor of burden allocated to suicide and ischemic heart disease. These findings emphasize the importance of including depressive disorders as a public-health priority and implementing cost-effective interventions to reduce its burden.

Intrathecal, polyspecific antiviral immune response in oligoclonal band negative multiple sclerosis

Background

Oligoclonal bands (OCB) are detected in the cerebrospinal fluid (CSF) in more than 95% of patients with multiple sclerosis (MS) in the Western hemisphere. Here we evaluated the intrathecal, polyspecific antiviral immune response as a potential diagnostic CSF marker for OCB-negative MS patients.

Methodology/Principal Findings

We tested 46 OCB-negative German patients with paraclinically well defined, definite MS. Sixteen OCB-negative patients with a clear diagnosis of other autoimmune CNS disorders and 37 neurological patients without evidence for autoimmune CNS inflammation served as control groups. Antibodies against measles, rubella, varicella zoster and herpes simplex virus in paired serum and CSF samples were determined by ELISA, and virus-specific immunoglobulin G antibody indices were calculated. An intrathecal antibody synthesis against at least one neurotropic virus was detected in 8 of 26 (31%) patients with relapsing-remitting MS, 8 of 12 (67%) with secondary progressive MS and 5 of 8 (63%) with primary progressive MS, in 3 of 16 (19%) CNS autoimmune and 3 of 37 (8%) non-autoimmune control patients. Antibody synthesis against two or more viruses was found in 11 of 46 (24%) MS patients but in neither of the two control groups. On average, MS patients with a positive antiviral immune response were older and had a longer disease duration than those without.

Conclusion

Determination of the intrathecal, polyspecific antiviral immune response may allow to establish a CSF-supported diagnosis of MS in OCB-negative patients when two or more of the four virus antibody indices are elevated.     

EMMPRIN,an upstream regulator of MMPs,in CNS biology

Matrix metalloproteinases (MMPs) are engaged in pathologies associated with infections, tumors, autoimmune disorders and neurological dysfunctions. With the identification of an upstream regulator of MMPs, EMMPRIN (Extracellular matrix metalloproteinase inducer, CD147), it is relevant to address if EMMPRIN plays a role in the pathology of central nervous system (CNS) diseases. This would enable the possibility of a more upstream and effective therapeutic target. Indeed, conditions including gliomas, Alzheimer's disease (AD), multiple sclerosis (MS), and other insults such as hypoxia/ischemia show elevated levels of EMMPRIN which correlate with MMP production. In contrast, given EMMPRIN's role in CNS homeostasis with respect to regulation of monocarboxylate transporters (MCTs) and interactions with adhesion molecules including integrins, we need to consider that EMMPRIN may also serve important regulatory or protective functions. This review summarizes the current understanding of EMMPRIN's involvement in CNS homeostasis, its possible roles in escalating or reducing neural injury, and the mechanisms of EMMPRIN including and apart from MMP induction.     

Plasma manganese, selenium, zinc, copper, and iron concentrations in patients with schizophrenia

A number of essential trace elements play a major role in various metabolic pathways. Selenium (Se), manganese (Mn), copper (Cu), zinc (Zn), and iron (Fe) are essential trace elements that have been studied in many diseases, including autoimmune, neurological, and psychiatric disorders. However, the findings of previous research on the status of trace elements in patients with schizophrenia have been controversial. We studied these elements in patients with a DSM-IV diagnosis of schizophrenia and compared them with sex- and age-matched healthy controls. Plasma Cu concentrations were significantly higher (p<0.01) and Mn and Fe concentrations were lower (p<0.05 and p<0.05, respectively) in schizophrenic patients than in controls. Se and Zn concentrations and protein levels did not differ between patients and healthy controls. These observations suggest that alterations in essential trace elements Mn, Cu, and Fe may play a role in the pathogenesis of schizophrenia. However, findings from trace element levels in schizophrenia show a variety of results that are difficult to interpret.     

Immediate health effects of an urban wildfire.

To document the immediate health effects of the urban wildfire that swept through parts of Alameda County, California, on October 20 and 21, 1991, we conducted a retrospective review of emergency department and coroner''s records. Nine hospitals (6 local and 3 outlying) were surveyed for the week beginning October 20, 1991. Coroner''s reports were reviewed for 25 identified fire-related deaths. A total of 241 fire-related emergency encounters, including 44 inpatient admissions, were recorded for 227 persons. Nearly a fourth of emergency department patients were seen for work-related injuries, more than half of which occurred among professional firefighters. Smoke-related disorders constituted more than half of all emergency department cases; of these, 61% had documented bronchospasm. Major trauma and burns contributed 1% and 4% of principal diagnoses, respectively; these were exceeded in number by corneal abrasions (13%), other medical problems (8%), and minor trauma (7%), among other diagnoses. All coroner''s cases involved extensive burns, many with documented smoke inhalation injury. While the Oakland-Berkeley fire storm resulted in a high case-fatality ratio among major burn cases (25/31), those who survived the initial fire storm did well clinically. Among emergency department patients, medical (particularly smoke-related) disorders outnumbered traumatic presentations by a ratio of more than 2 to 1.     

Conservative Treatment of Chronic Heart Block

A study of 203 patients with chronic heart block treated with oral long-acting isoprenaline showed that 85 (42%) were maintained satisfactorily on the drug for a mean period of 18.2 months. The survival rates at one, two, and three years were 76%, 64%, and 57% respectively. In 115 patients treatment by pacing became necessary to control symptoms, and in these patients the survival rates at one, two and three years were 83%, 72%, and 60%.The two most valuable guides to patients'' response to oral isoprenaline are the response to a trial dose of intravenous isoprenaline and the type of dysrhythmia associated with their Adams-Stokes attacks. Patients with heart failure with slow ventricular rates and those with angina of effort do not respond to treatment with sympathomimetic drugs.The majority of patients with chronic heart block are elderly, and in view of the complexity of pacing systems, and the need for skilled supervision of paced patients, oral long-acting isoprenaline remains of value in the longterm management of chronic heart block, provided patients are carefully selected for this form of therapy.     

Thymoma,myasthenia gravis,erythroblastopenic anemia and systemic lupus erythematosus in one patient

A 50-year-old woman who initially had myasthenia gravis subsequently presented with thymoma, erythroblastopenic anemia and systemic lupus erythematosus during 17 years of follow-up. In a review of the literature no similar documented cases were found, although 14 patients were reported with three of the above diseases, two also having positive LE cell tests. An association of several autoimmune disorders in one patient may be more frequent than was previously believed.     

Evidence for a primary autoimmune type of diabetes mellitus.

Sixty-eight patients with longstanding diabetes and persistent islet-cell antibody and 35 with coexistent diabetes and Graves''s disease or primary myxoedema were studied with particular reference to the HLA system and autoantibody patterns. A higher incidence of HLA-B8 than normal was observed in the two groups. An additive relative risk exists when type I diabetes and autoimmune thyroid disease coexist, indicating that different HLA-linked genes may confer susceptibility to the pancreatic and thyroid disorders. Other characteristics, including female predominance, a later onset of diabetes, and a strong family history of autoimmune endocrinopathy, provide further evidence that this form of diabetes is aetiologically distinct from that generally seen in children. These results support the hypothesis of a primary autoimmune type of diabetes mellitus.     

Oxidation Products and Antioxidant Markers in Plasma of Patients with Graves' Disease and Toxic Multinodular Goiter: Effect of Methimazole Treatment

Oxidative stress plays an important role in hyperthyroidism-induced tissue damage, as well as in development of autoimmune disorders. To clarify influence of thyroid metabolic status and autoimmune factors on blood extracellular indices of reactive oxygen species (ROS) generation and free radical scavenging in hyperthyroidism, we studied patients with newly diagnosed and untreated Graves' disease without infiltrative ophthalmopathy (17 female and 8 male, aged 41.8±8.9) and toxic multinodular goiter (15 female and 9 male, aged 48.4±10.1) under the same antithyroid treatment protocol. Initially and after achievement of stable euthyroidism with methimazole, plasma levels of hydrogen peroxide (H²O²), lipid hydroperoxides (ROOH) and ceruloplasmin (CP) and serum concentrations of thiobarbituric acid-reacting substances (TBARS) were determined. Similarly, activities of plasma superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR) were assayed. The results were compared to those of age- and sex-matched controls. Average duration of hyperthyroidism and treatment period were similar in both patients groups. H²O², ROOH and TBARS concentrations were significantly higher in hyperthyroid patients compared to controls. Hyperthyroidism caused an evident increase in SOD and CAT activities and CP level, as well as a decrease in GPx and GR activities. Achievement of euthyroidism resulted in normalization of all analyzed parameters in both hyperthyroid patients groups. These findings suggest that the changes in blood extracellular indices of oxidative stress and free radical scavenging in hyperthyroid patients are influenced by thyroid metabolic status, and are not directly dependent on autoimmune factors present in Graves' disease.

Diagnostic and prognostic biomarker discovery strategies for autoimmune disorders

Current clinical, laboratory or radiological parameters cannot accurately diagnose or predict disease outcomes in a range of autoimmune disorders. Biomarkers which can diagnose at an earlier time point, predict outcome or help guide therapeutic strategies in autoimmune diseases could improve clinical management of this broad group of debilitating disorders. Additionally, there is a growing need for a deeper understanding of multi-factorial autoimmune disorders.Proteomic platforms offering a multiplex approach are more likely to reflect the complexity of autoimmune disease processes. Findings from proteomic based studies of three distinct autoimmune diseases are presented and strategies compared. It is the authors' view that such approaches are likely to be fruitful in the movement of autoimmune disease treatment away from reactive decisions and towards a preventative stand point.     

Self-inflicted injury: a follow-up study of 43 patients.

Forty-three patients, 38 women and 5 men, with self-inflicted skin lesions were studied. Thirty-three were followed up for up to 22 years. In most cases dermatitis artefacta was only one incident in a long history of psychogenic illness. Of the 43 patients, 13 (30%), 12 women and one man, continued to produce lesions or were disabled with other psychiatric disorders more than 12 years after the onset of symptoms. Prognosis was difficult but recovery seemed to occur when the patient''s life circumstances changed rather than as a result of treatment.     

Higher Risk of Thyroid Disorders in Young Patients with Type 1 Diabetes: A 12-Year Nationwide,Population-Based,Retrospective Cohort Study

Background

The association between type 1 diabetes and thyroid autoimmunity has been studied in various populations, but seldom on Taiwanese children and adolescents. Therefore, the aim of this study was to examine the incidence of autoimmune thyroid disorders in Taiwanese children and adolescent patients with type 1 diabetes, based on data from a nationwide, population-based, health claims database.

Methods

Using Taiwan’s National Health Insurance Research Database, we identified 3,652 patients with type 1 diabetes between 2000 and 2012. A comparison cohort was assembled, which consisted of five patients without type 1 diabetes, based on frequency matching for sex and 3-year age interval, for each patient with type 1 diabetes. Both groups were followed until diagnosis of thyroid disorders or the end of the follow-up period. Poisson regression models were used to calculate incidence rate ratios for the thyroid disorders between the type 1 diabetes cohort and the comparison cohort.

Results

Simple and unspecified goiter (International Classification of Diseases, 9^th Revision, Clinical Modification [ICD-9-CM] code 240), thyrotoxicosis (ICD-9-CM code 242), unspecified hypothyroidism (ICD-9-CM code 244.9), and thyroiditis (ICD-9-CM code 245) showed significantly higher incidences in the type 1 diabetes cohort compared with the control cohort, with incidence rate ratios of 2.74, 6.95, 6.54, 16.07, respectively.

Conclusions

Findings from this nationwide, population-based cohort study showed that the incidences of autoimmune thyroid disorders were significantly higher in Taiwanese children and adolescents with type 1 diabetes compared with those without the disease.
