Recommendations of the Mexican College of Rheumatology for the management of psoriatic arthritis.

Unlabelled: Psoriatic arthritis is a chronic systemic inflammatory disease that affects the skin, musculoskeletal structures and other organs and systems compromising functionality, quality of life and reducing the life expectancy of patients. It is a complex disease that requires specialist and timely care and management. The alternatives for treating the manifestations of psoriatic arthritis have increased and the effect of the different agents on specific manifestations has been clarified in recent studies.

Psoriatic arthritis in patients with psoriasis: A clinical-epidemiological study at a dermatology center in western Mexico.

Background/objective: Psoriatic arthritis (PsA) is a chronic inflammatory illness. Approximately, 15% of psoriasis patients have undiagnosed PsA. In Mexico, we found no related studies.

Nevoid acanthosis nigricans: Report of four cases localized to the umbilicus.

Nevoid acanthosis nigricans is a rare, benign form of acanthosis nigricans. Of the 24 cases documented in the literature, only two are exclusively localized to the umbilicus. We present four cases of nevoid acanthosis nigricans localized to the umbilicus; in patients less than 25 years of age, with no known co-morbidities, three of whom were females.

A potential inflammatory role of IL-31 in psoriatic arthritis: A correlation with Th17 cytokine profile.

The goals of our study were to determine the possible association of interleukin (IL)-31 with Th17 cytokine profile in serum and to quantify retinoic acid-related orphan receptor C () mRNA expression in psoriatic arthritis (PsA) patients. This cross-sectional study was conducted in 50 patients with PsA and 30 control subjects (CS) matched by age and gender. The cytokine serum levels were quantified by magnetic bead-based assay using the Bio-Plex MAGPIX system, and mRNA expression was determined by quantitative polymerase chain reaction (qPCR).

[Mexican consensus on the diagnosis and treatment of atopic dermatitis in adolescents and adults].

Background: The diagnostic approaches and therapeutic strategies of atopic dermatitis (AD) are generally inconsistent among physicians and health institutions.

Objective: To develop a consensus statement among experts to reduce the variations in practice regarding the diagnosis and treatment of patients ≥ 12 years with AD to improve their care.

Methods: Systematic literature search in PubMed and GREAT.

Ácido úrico sérico como marcador de gravedad clínica y comorbilidad en psoriasis en placas.

IntroducciÓn: La hiperuricemia es común en pacientes con psoriasis. Se ha sugerido que la elevación de ácido úrico en psoriasis está fuertemente asociada con morbilidad cardiovascular.

Objetivo: Determinar la relación entre niveles de ácido úrico, gravedad clínica medida por Psoriasis Area Severity Index (PASI), Body Surface Area (BSA) y static Physician's Global Assessment (sPGA) en pacientes con psoriasis en placas y comorbilidades ungueales y artritis psoriásica.

Expression of MIF and TNFA in psoriatic arthritis: relationship with Th1/Th2/Th17 cytokine profiles and clinical variables.

Psoriatic arthritis (PsA) is an autoimmune inflammatory disease associated with psoriasis. The cause of this pathology is still unknown, but research suggests the diseases are caused by a deregulated cytokine production. MIF is a cytokine associated with immunomodulation of Th1, Th2, and Th17 cytokine profiles in inflammatory diseases.

Macrophage migration inhibitory factor (MIF) promoter polymorphisms (-794 CATT5-8 and -173 G>C): association with MIF and TNFα in psoriatic arthritis.

Psoriatic arthritis (PsA) is an autoimmune disease with a complex interaction of gene and with a dysregulation of pro-inflammatory cytokine such as Macrophage migration Inhibitory Factor (MIF) and Tumor Necrosis Factor-alpha (TNFα). Two polymorphisms identified in the promoter region of the MIF gene have been described: the STR-794 CATT5-8 (rs5844572) and the SNP-173 G>C (rs755622), which are associated with increased MIF levels in circulation and with autoimmune diseases in several populations. In this case-control study we investigated whether commonly occurring functional MIF polymorphisms are associated with PsA susceptibility and clinical variables as well as with MIF and TNFα serum levels in a Mexican-Mestizo population.
