Advances in the knowledge of the pathophysiological mechanisms of rheumatic diseases have made it possible to identify defined targets to which to direct monoclonal antibodies with therapeutic purposes, a form of treatment commonly called biological therapy. A significant number of these biological drugs are approved by regulatory agencies and are included in the recommendations for the management of various rheumatic diseases; including autoimmune systemic rheumatic diseases; but also spondyloarthritis and other rheumatic diseases. A large number of monoclonal antibodies are in diverse research phases and it is expected that in near future more of these drugs will become available. Used properly they are safe and effective therapies, but they use can be associated with side effects, some of which can be serious. In general they have a high cost and despite the appearance of biosimilar m...

Systemic sclerosis sine Scleroderma is an uncommon form of systemic compromise of this disease, in the abscense of cutaneous manifestations. We present the case of a 71 years-old woman, body mass index (BMI) in 16.9 kg/m2, with history of hypothyroidism and chronic constipation, who goes to the emergency with pain, abdominal bloating, and nausea. An abdominopelvic tomography was made, reporting a collapse of the gastric chamber, some segments of intestinal loops distended with signs of fecalization in the small intestine. A colonoscopy described severe dolicocolon. We observed indurated plaques in left elbow and in both buttocks. Lab tests: ANA 1/640 with anticentromeric pattern, anticentromere antibodies = 227 U/mL (0-25), Anti-SCL-70 = 1.9 U/mL (0-25), anti-RNP = 0.1 U/mL (0-25). Peri-ungueal cappilaroscopy 200x showed mega capillaries. Clinical diagnosis was systemic sclerosis sine sc...

Se realizó una tomografía abdomino-pélvica encontrándose cámara gástrica colapsada, asas intestinales con algunos segmentos distendidos, con signos de fecalización de asa delgada. La colonoscopía describió dolicocolon severo. Se observaron placas induradas en codo derecho y en ambos glúteos. Los exámenes auxiliares: ANA 1/640 patrón centromérico, anticuerpos anticentrómero = 227 U/mL (valor normal – VN: 0-25), Anti SCL-70 = 1,9 U/mL (VN 0-25) y anti RNP = 0,1 U/mL (VN 0-25). La capilaroscopí...
