Analysis of novel Sjogren's syndrome autoantibodies in patients with dry eyes.

Dry eye is a common problem in Ophthalmology and may occur for many reasons including Sjogren's syndrome (SS). Recent studies have identified autoantibodies, anti-salivary gland protein 1 (SP1), anti-carbonic anhydrase 6 (CA6) and anti-parotid secretory protein (PSP), which occur early in the course of SS. The current studies were designed to evaluate how many patients with idiopathic dry eye and no evidence of systemic diseases from a dry eye practice have these autoantibodies.

Update on the use of biologics in vasculitides.

Vasculitides are disease in which injury to blood vessels leads to various degrees and types of organ dysfunction. They are subdivided into different groups dependent on the size of blood vessels involved as well as other particular clinical features. Therapy is dependent upon the size of the blood vessels involved and the nature of the disease. For medium and large vessel vasculitides, glucocorticoids, cyclophosphamide, azathioprine and methotrexate have been the mainstay for induction and maintenance of remission. Because of potential for side effects from standard therapies, various biologic agents have been evaluated in the treatment of ANCA positive vasculitis (AAV), cryoglobulinemic vasculitis, Behcet's disease and Takayasu's Arteritis (TAK). In this article, we present a review on biologic agents used in various vasculitides.

Update on the use of biologics in lupus.

Systemic lupus erythematosus is more than a heterogeneous autoimmune disease. It is in fact a syndrome of many different clinical genotypes and phenotypes. This review covers the most recently studied monoclonal antibodies and those currently being investigated. The key trials are summarized, including those for biologics on the market for two decades and those just approved for lupus less than two years ago. The focus will be on the following four: Rituximab, Abatacept, Belimumab, and Epratuzumab. It is a challenge to design the perfect trial and study patients with this disease as each has his or her own unique manifestations, biological markers, and underlying genetic background. However, as our understanding of the immune mechanisms involved in lupus increases; novel therapies will emerge that can be utilized for appropriately selected patients.

Xerophthalmia of Sjogren's Syndrome Diagnosed with Anti-Salivary Gland Protein 1 Antibodies.

The purpose of this report is to describe 2 patients with persistent severe dry eyes, positive Schirmer tests for Sjogren's syndrome (SS) but lacking antibodies to either Ro or La. These patients were diagnosed to have SS by detecting antibodies to salivary gland protein 1 (Sp1) and parotid secretory protein (PSP). This report emphasizes the existence of patients with SS who lack antibodies to either Ro or La and may therefore be misdiagnosed. Detection of novel autoantibodies, including antibodies to Sp1 and PSP, are helpful in identifying these patients. Initial presentation may simply be dry eyes.

Anti-salivary gland protein 1 antibodies in two patients with Sjogren's syndrome: two case reports.

Current diagnostic criteria for Sjogren's syndrome developed by the American College of Rheumatology include the presence of antinuclear antibodies, rheumatoid factor, anti-Ro or anti-La autoantibodies. The purpose of this report is to describe two patients with biopsy-proven Sjogren's syndrome lacking these autoantibodies but identified by antibodies to salivary gland protein 1. Diagnosis was delayed until salivary gland tumors developed in these patients because of the lack of the classic autoantibodies. This report emphasizes the existence of patients with primary Sjogren's syndrome who lack autoantibodies anti-Ro or anti-La and may therefore be misdiagnosed. Antibodies to salivary gland protein 1 identify some of these patients.

Mitochondrial myopathy presenting as fibromyalgia: a case report.

To the best of our knowledge, we describe for the first time the case of a woman who met the diagnostic criteria for fibromyalgia, did not respond to therapy for that disorder, and was subsequently diagnosed by biochemical and genetic studies with a mitochondrial myopathy. Treatment of the mitochondrial myopathy resulted in resolution of symptoms. This case demonstrates that mitochondrial myopathy may present in an adult with a symptom complex consistent with fibromyalgia.

Metabolic myopathy presenting with polyarteritis nodosa: a case report.

To the best of our knowledge, we describe for the first time a patient in whom an unusual metabolic myopathy was identified after failure to respond to curative therapy for a systemic vasculitis, polyarteritis nodosa. We hope this report will heighten awareness of common metabolic myopathies that may present later in life. It also speculates on the potential relationship between metabolic myopathy and systemic vasculitis.
