Antimelanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis: clinical features and outcomes in a racially diverse patient cohort.

Background: The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S.

Autoimmune thyroid disease modifies the clinical expression of hand osteoarthritis in older people: a third National Health and nutrition examination survey study.

Introduction: The risk factors linked to hand osteoarthritis (OA) that contribute to its distinct symptoms and clinical presentation are not thoroughly understood. This study aimed to examine whether the autoimmune thyroid disease (AITD) autoantibodies, anti-thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TgAb), associate with hand OA and symptomatic hand OA in the Third National Health and Nutrition Examination Survey (NHANES III).

Materials And Methods: We included 2,429 persons from NHANES III ≥60 years of age.

Autoimmune thyroid disease and rheumatoid arthritis: where the twain meet.

Autoimmune thyroid disease (AITD) is the most prevalent autoimmune disease. It shares multiple genetic, clinical, and serologic characteristics with rheumatoid arthritis (RA). Although frequently described as a classic form of single-organ autoimmunity, the AITD disease burden in a subset of patients extends well beyond the thyroid gland.

Association of the anti-thyroid peroxidase antibody with chronic hand pain in older adults in the Third National Health and Nutrition Examination Survey: a cross-sectional study.

Background: Autoimmune thyroid disease (AITD) is the commonest autoimmune disease. Although viewed as a classic form of single-organ autoimmunity, AITD is increasingly associated with non-thyroid sequelae including musculoskeletal manifestations and chronic pain syndromes. However, large population-based studies are needed.

A Case of Microscopic Polyangiitis Complicated by Mucormycosis: A Dangerous Balancing Act.

Microscopic polyangiitis (MPA) is a rare antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis marked by renal involvement, which often leads to rapidly progressive glomerulonephritis. Immunosuppressive treatment is necessary to prevent irreparable organ damage. On the other hand, mucormycosis is a rare and devastating opportunistic fungal infection with a high mortality rate in both immunosuppressed and immunocompetent individuals.

Association of anti-thyroid antibodies with radiographic knee osteoarthritis and chondrocalcinosis: a NHANES III study.

Objectives: To examine the relationships between radiographic knee osteoarthritis (RKOA), symptomatic radiographic knee osteoarthritis (sRKOA), and chondrocalcinosis, as outcome variables, and the autoimmune thyroid disease (AITD) autoantibodies, anti-thyroid peroxidase antibody (TPOAb) and anti-thyroglobulin antibody (TgAb), in the Third National Health and Nutrition Examination Survey (NHANES III) data source.

Methods: NHANES III provided data on 2291 persons over the age of 60 years that included the osteoarthritis variables of interest RKOA, sRKOA and chondrocalcinosis, and the thyroid autoantibodies TPOAb and TgAb. A log-binomial regression model was fit to examine the relationships between anti-thyroid autoantibodies and RKOA.

Rapid Implementation of a Multidisciplinary COVID-19 Cytokine Storm Syndrome Task Force.

Objective: Patients with coronavirus disease 2019 (COVID-19) can progress to a state of unregulated inflammation called cytokine storm syndrome (CSS). We describe formation and operation of a COVID-19 multidisciplinary consultation service that was allowed to individualize treatment for critically ill patients with COVID-19 during the pandemic.

Methods: Institutional experts from different subspecialties formed a COVID-19 CSS task force at Montefiore Medical Center, Bronx, NY.

Rheumatic associations of autoimmune thyroid disease: a systematic review.

To investigate specific disease patterns in the rheumatic manifestations associated with autoimmune thyroid disease (AITD) through a systematic literature review. We performed a systematic review using the Medline OVID, PubMed, EMBASE, and Web of Science databases through May 2018 for experimental and observational studies that explored the association of AITD with degenerative joint disease (DJD), osteoarthritis (OA), chronic widespread pain (CWP) and fibromyalgia syndrome (FMS), and seronegative inflammatory arthritis (IA). A total of 2132 articles were identified.

Effects of Unripe Musa Paradisiaca on the Histochemistry of the Testis and Testosterone Levels in Adult Albino Rats.

This study was aimed at determining the effects of the unripe fruit of Musa paradisiaca on the testis andtestosterone levels in male Wistar rats. The animals were grouped into three, comprising a control, and 2 treatment groupsadministered with different doses (500 mg/kg and 1000 mg/kg) daily of the fruit flour over 28 days. Histochemical evaluationof the testes was done using Haematoxylin and Eosin, Periodic acid Schiff's (PAS) and Feulgen staining techniques, whilethe serum and homogenised testicular tissue were evaluated for testosterone levels using Accu-Bind ELISA Kit.

The prevalence and distribution of the amyloidogenic transthyretin (TTR) V122I allele in Africa.

Background: Transthyretin (TTR) pV142I (rs76992529-A) is one of the 113 variants in the human TTR gene associated with systemic amyloidosis. It results from a G to A transition at a CG dinucleotide in the codon for amino acid 122 of the mature protein (TTR V122I). The allele frequency is 0.

Association of spinal degenerative disc disease with thyroid autoimmunity.

Objectives: Autoimmune thyroiditis (ATD) has been linked to various forms of arthritis. The relationship with spinal degenerative disc disease (DDD) is not known. We studied the association between ATD and spinal DDD.

The transcription, translation, transport-trail and autoimmunity: Guilt by association.

The autoimmune connective tissue diseases (ACTD) are a group of diseases which share clinical features and genetic inheritance. They are characterized by systemic autoimmunity and autoantibody production with a striking predilection for cellular components involved in transcription, translation and cellular transport. Although multiple triggers of autoimmunity have been proposed for this group of diseases including microbial agents such as viruses and bacteria, drugs, ultraviolet light, environmental toxins, stress, hormones and heavy metals, the prominence of autoantibodies to components of the transcription, translation, cellular transport-trail (TTTT) suggests that the agent(s) triggering the autoimmune response potentially utilize the TTTT.

Prevalence of the amyloidogenic transthyretin (TTR) V122I allele in 14 333 African-Americans.

Background: Transthyretin (TTR) V122I (rs76992529) is one of 111 variants caused by point mutations in the coding sequence of the human TTR gene that are associated with systemic amyloidosis. It results from a G to A transition at a CG dinucleotide in codon 142(122 of the mature protein) of the gene and has been described almost exclusively in people of African descent. Several series have reported allele frequencies from 0.

Association of antithyroid peroxidase antibody with fibromyalgia in rheumatoid arthritis.

To investigate how autoimmune thyroiditis (ATD) affects the clinical presentation of established rheumatoid arthritis (RA) with particular reference to fibromyalgia and chronic widespread pain (CWP). A cohort of 204 patients with RA for whom the presence or absence of autoimmune thyroid antibodies was documented was examined for the relationships between thyroid autoantibodies and fibromyalgia or CWP. We identified 29 % who tested positive for antithyroid peroxidase antibodies (TPOAb).

Rheumatic symptoms in autoimmune thyroiditis.

Autoimmune thyroiditis (ATD) is generally regarded as a classic example of single organ autoimmunity with a high association with endocrine thyroid disorders. However, it is closely associated with several autoimmune diseases including rheumatologic syndromes and has long been known to have several rheumatic manifestations particularly in association with hypothyroidism. More recently, it has also been implicated in rheumatologic syndromes in the absence of hypothyroidism or subclinical hypothyroidism.

Fibromyalgia and chronic widespread pain in autoimmune thyroid disease.

Fibromyalgia and chronic widespread pain syndromes are among the commonest diseases seen in rheumatology practice. Despite advances in the management of these conditions, they remain significant causes of morbidity and disability. Autoimmune thyroid disease is the most prevalent autoimmune disorder, affecting about 10 % of the population, and is a recognized cause of fibromyalgia and chronic widespread pain.

Beneficial effects of low dose Musa paradisiaca on the semen quality of male Wistar rats.

Background: This study aimed at determining the effects of administration of mature green fruits of Musa paradisiaca on the semen quality of adult male Wistar rats.

Materials And Methods: THE ANIMALS USED FOR THE STUDY WERE GROUPED INTO THREE: the control group, given 2 ml of double distilled water, a low dose group given 500 mg/kg/day and a high dose group given 1000 mg/kg/day of the plantain fruits, which was made into flour, and dissolved in 2 ml of double distilled water for easy oral administration.

Results: Significant increment in the semen parameters was noticed in animals that received a lower dose of the plantain flour, but those animals who received the high dose had marked and very significant reduction in sperm cell concentration and percentage of morphologically normal spermatozoa.

Rheumatic manifestations of euthyroid, anti-thyroid antibody-positive patients.

The aim of this study is to define the rheumatic manifestations of euthyroid patients with chronic lymphocytic thyroiditis (CLT) but without a well-defined connective tissue disease. Forty-six consecutive patients with anti-thyroid peroxidase (αTPO) and/or anti-thyroglobulin antibodies (αTG), and normal thyroid function in the absence of a well-defined connective tissue disease were included in a case-cohort study. Arthralgias were a presenting complaint in 98 % of patients.

JAK2 inhibition in murine systemic lupus erythematosus.

Systemic lupus erythematosus is a systemic autoimmune disease characterized by the presence of myriad autoantibodies, some with pathogenic potential, and diverse clinical manifestations. Involvement of the kidney is a major cause of morbidity and mortality in human lupus patients and in murine models of the disease. It is hoped that more specific inhibition of crucial disease pathways would improve patient response rates, while reducing the considerable rates of drug-related side effects associated with current therapy.

Rheumatic manifestations of autoimmune thyroid disease: the other autoimmune disease.

Autoimmune thyroid disease (AITD) is an inflammatory thyroiditis that in some cases is characterized by lymphocytic infiltration of the thyroid gland, also referred to as chronic lymphocytic thyroiditis or Hashimoto thyroiditis. Hashimoto thyroiditis is one of the commonest causes of hypothyroidism. Hypothyroidism has been associated with osteoarthritis (OA) and inflammatory forms of arthritis and with several well defined connective tissue diseases, which in turn can cause arthritis.

Why are some amyloidoses systemic? Does hepatic "chaperoning at a distance" prevent cardiac deposition in a transgenic model of human senile systemic (transthyretin) amyloidosis?

In the human systemic amyloidoses caused by mutant or wild-type transthyretin (TTR), deposition occurs at a distance from the site of synthesis. The TTR synthesized and secreted by the hepatocyte circulates in plasma, then deposits in target tissues far from the producing cell, a pattern reproduced in mice transgenic for multiple copies of the human wild-type TTR gene. By 2 yr of age, half of the transgenic males show cardiac deposition resembling human senile systemic amyloidosis.

Relation of clinical, echocardiographic and electrocardiographic features of cardiac amyloidosis to the presence of the transthyretin V122I allele in older African-American men.

Previous studies have shown that 3% to 4% of African Americans carry an amyloidogenic allele of the human serum protein transthyretin (TTR V122I). The allele appears to have an absolute anatomic risk for cardiac amyloid deposition after 65 years of age. In this study, a case-control comparison was performed of clinical, echocardiographic, and electrocardiographic characteristics of 23 age at risk carriers of the amyloidogenic allele and 46 age-, gender-, and ethnically matched noncarriers being evaluated for cardiac disease using standard clinical testing.
