Jatoba ( L.) Pod Residue: A Source of Phenolic Compounds as Valuable Biomolecules.

This study aimed at investigating the chemical composition and a selected group of bioactivities of jatoba ( L.) pod residue. An aqueous extract (deionized water; AE) and a hydroethanolic extract (ethanol: deionized water, 70:30 /; ETOH) were obtained via maceration.

Clinical disease activity index applicability in lupus arthropathy: Unraveling underdiagnosed joint activity.

Introduction: Lupus arthropathy (LA) ranges from arthralgia and non-deforming arthritis to severe forms such as Jaccoud-type deformities and mutilating arthritis. Considering the evolving concept of LA, measuring arthritis activity in lupus patients may require a more practical and sensitive tool other than the classical composite scores.

Methods: In this cross-sectional study, we evaluated the articular pattern of a sample of SLE patients which were divided into those that scored in articular domain on Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and those with activity arthritis using the Clinical Disease Activity Index (CDAI).

Evaluation of the Inflammatory Cytokines and IL-10 Network in Individuals Co-infected With Human T-Cell Lymphotropic Virus and Hepatitis C Virus (HTLV/HCV).

Background: Co-infection between the human T-cell lymphotropic virus (HTLV) and the hepatitis C virus (HCV) can modify the natural history of HCV infection. The aim of this study was to describe the inflammatory cytokines and IL-10 network in patients co-infected with HTLV and HCV viruses in Bahia, Brazil.

Methods: Samples from 31 HTLV/HCV co-infected individuals and 27 HCV monoinfected individuals were evaluated.

Videocapillaroscopic Findings in Patients With Systemic Lupus Erythematosus With or Without Jaccoud Arthropathy.

Background/objective: Systemic lupus erythematosus (SLE) is an autoimmune disease that can present changes in blood vessels, which can be evaluated by periungual nailfold videocapillaroscopy (VCP). This technique is important for the diagnosis of systemic sclerosis and to identify individuals with Raynaud phenomenon at higher risk of developing systemic sclerosis. This study aims to describe the videocapillaroscopic profile of a series of SLE patients and to investigate if the VCP pattern is different among those with Jaccoud arthropathy (JA) compared with those without.

Scleroderma with Acro-Osteolysis and Papular Mucinosis Resembling Multicentric Reticulohistiocytosis.

Objectives: We describe a case of systemic sclerosis (SS) with acro-osteolysis associated with cutaneous mucinosis, usually characterized by mucin deposition in the skin. The main differential diagnosis was multicentric reticulohistiocytosis due to the presentation of papulonodular skin lesions.

Materials And Methods: A physical examination, imaging studies and laboratory tests were performed.

IgG1 and IgG4 antibodies against Core and NS3 antigens of hepatitis C virus.

Introduction: IgG subclasses involved in the immune response to hepatitis C virus (HCV) antigens have been rarely studied. We investigated the immune response mediated by IgG1 and IgG4 antibodies against the recombinant core and NS3 antigens in patients with chronic hepatitis C.

Methods: Sixty patients infected with HCV genotype 1 without antiviral treatment and 60 healthy subjects participated in the study.

Adiponectin levels and insulin resistance among patients with chronic hepatitis C.

Chronic hepatitis C virus (HCV) infection is associated with insulin resistance (IR), rapid disease progression, and decreased virological response to antiviral treatment. In addition, obesity is a risk factor for chronic hepatitis C evolution and is associated with IR. As adiponectin is an adipokine that is associated with obesity and IR, this study aimed to investigate serum levels of adiponectin among patients with HCV infection and IR.

Sonographic Findings of Hands and Wrists in Systemic Lupus Erythematosus Patients With Jaccoud Arthropathy.

Introduction: Jaccoud arthropathy (JA) is a deforming nonerosive arthropathy, characterized by the presence of "reversible" joint deformity. The study aims at describing the main musculoskeletal ultrasound (US) findings of a series of systemic lupus erythematosus (SLE) patients with JA.

Methods: Consecutive patients diagnosed as having JA and SLE were included in the study.

Disruption of Splenic Lymphoid Tissue and Plasmacytosis in Canine Visceral Leishmaniasis: Changes in Homing and Survival of Plasma Cells.

Visceral leishmaniasis (VL) is a disease caused by Leishmania infantum, which is transmitted by phlebotomine sandflies. Dogs are the main urban reservoir of this parasite and the disease presents similar characteristics in both humans and dogs. In this paper, we investigated the potential pathways involved in plasma cell replacement of normal cell populations in the spleen, with respect to disease severity in dogs from an endemic area for visceral leishmaniasis.

Profile of autoantibodies in Jaccoud's arthropathy.

Objective: To compare the frequency of different autoantibodies in a group of patients with Jaccoud's arthropathy (JA) secondary to systemic lupus erythematosus (SLE) with those without JA.

Methods: A group of SLE patients with JA was compared with another group of SLE patients without this complication, matched by age and gender, regarding the presence of autoantibodies. Antibodies to cyclical citrullinated peptides (anti-CCP) and to mutated citrullinated vimentin (anti-MCV) as well as anti-SSA/Ro, anti-SSB/La, anti-Sm and anti-RNP and anticardiolipin (aCL) antibodies were searched by ELISA, using commercial kits.
