Examining The Matrix: A Case Of Anti-Nuclear Matrix Protein 2 (Nxp-2) Positive Dermatomyositis, Victoria Cuello, Ramiro Oquita, Emilia Dulgheru
Research Symposium
Background: Dermatomyositis is a disease characterized by proximal muscle weakness, elevated muscle enzymes and cutaneous skin findings including heliotrope rash, periungual erythema, Gottron’s papules/sign and shawl-sign. Myositis-specific autoantibodies (MSA) can be used to predict disease manifestations, response to therapy and prognosis. Specifically, patients with dermatomyositis with positive anti-nuclear matrix protein (NXP-2) typically present with classical skin findings, subcutaneous edema, profound muscle weakness, severe dysphagia and hypophonia.
Case Presentation: A 21-year-old Hispanic lady presented to the hospital for severe muscle weakness. She reported soreness in her thighs for three months prior to presentation followed by arm soreness. She also developed a …

Research Symposium
Introduction: Mixed cryoglobulinemia syndrome (MCS) is a systemic inflammatory syndrome affecting small-medium sized vessels due to the presence of type II or III cryoglobulins in the serum. MSC can manifest as systemic vasculitis with symptoms varying from weakness, arthralgia, palpable purpura, peripheral neuropathy, and renal involvement. The most common cause of MCS includes lymphoproliferative disorders, autoimmune diseases and viral infections, with hepatitis C virus (HCV) being the most common etiology.
Case Presentation: A 60-year-old lady was referred to our office for evaluation of rheumatoid arthritis. She reported history of bilateral thumb pain, bilateral knee pain associated with episodes of swelling, …

That Which Keeps On Giving - A Case Of Class Iv Diffuse Proliferative Lupus Nephritis In A Hispanic Woman With Underlying Systemic Lupus Erythematosus, Josenny L. Rodriguez-Paez, Christine E. Loftis, Rosa White-Guedez
Research Symposium
Background: Glomerulonephritis is the primary cause of morbidity and mortality of systemic lupus erythematosus (SLE). Lupus nephritis is characterized by immune complex deposition in the mesangium leading to complement activation and hypocomplementemia. Studies show that up to 60% of adults with lupus develop renal involvement and it has been well established that Hispanic patients show poorer outcomes than Caucasians despite advances in treatment. Preserved kidney function with new-onset proteinuria should raise clinical suspicion for acute lupus nephritis. Further evaluation with a kidney biopsy is paramount in establishing a diagnosis, helping to define treatment strategy, and determining response to treatment.
