Dopaminergic Agents in Rheumatoid Arthritis

AbstractClinical evidences suggest a causal relationship between rheumatoid arthritis (RA) and the dopaminergic system, and several studies described an alteration of the disease in patients treated with dopaminergic agents. Despite these interesting results, potential direct effects of dopamine on RA have not been intensively considered until the last decade. Recent studies confirm a direct effect of dopamine on the systemic immune response as well as on bone remodeling and on joint inflammation, both in humans and in different animal models of arthritis. While more research is necessary to accurately determine the effect of dopamine in RA, these results are encouraging and support a possible use of dopaminergic drugs for the treatment of arthritis in the future. Moreover, they point out that dopaminergic agents use to treat comorbidities, might influence the immune response and the disease progression in RA patients. This review summarizes the current knowledge about the effects of dopaminergic drugs on RA and describes the potential of dopaminergic drugs as future therapeutic strategy in arthritis.Graphical Abstract

VasconcelosABSTRACTMacrophage migration inhibitory factor (MIF) is a pleiotropic cytokine that is produced by many cell types in situations of homeostasis or disease. One of its functions is to act as a proinflammatory molecule. In humans, several studies have shown that MIF levels become elevated in the serum, urine, cerebrospinal flu...

AbstractPurpose of ReviewThe purpose of this review is to discuss the literature on associations between vitamin D and periodontal disease, including its strengths and weaknesses. Future direction for continued work in this area is provided.Recent FindingsResearch in cross-sectional cohorts, surveys, and case-control studies provide support for a role of vitamin D in periodontal disease, especially using clinical indicators such as bleeding on probing and clinical attachment loss. However, these studies have a number of limitations. They cannot establish temporality of these associations. Most case-control studies have bee...

We aimed to evaluate the periodontal status in RA with and without baricitinib, a Jan...

The barrier between mind and body appears to be crumbling. Clinical practice and public perception need to catch upUnlikely as it may seem, #inflammation has become a hashtag. It seems to be everywhere suddenly, up to all sorts of tricks. Rather than simply being on our side, fighting infections and healing wounds, it turns out to have a dark side as well: the role it plays in causing us harm.It ’s now clear that inflammation is part of the problem in many, if not all, diseases of the body. And targeting immune or inflammatory causes of disease has led to a series of breakthroughs, from new treatments for rheumatoid ...

In this study, we tested the role of damp and heat environments in exacerbating RA inflammation and the anti-inflammatory effect of BHGZ, based on succinate/SUCNR1/IL-1β pathway in the adjuvant arthritis (AA) model with damp and heat environment (AA + DHE). Results showed that paw swelling and synovial pathology were significantly increased in AA rats, and these results were aggravated by stimulation in damp and heat environment. BHGZ improved AA + DHE rats' paw swelling, synovial hyperplasia, and inflammatory cell infiltration and reduced IL-1β. In addition, AA rats significantly incr...

AbstractAimsTo (1) determine the reliability and validity of the Bristol Rheumatoid Arthritis Fatigue scale (BRAF-NRS) in patients with psoriatic arthritis (PsA) and (2) examine possible clinical associations of worse fatigue in PsA.MethodsStudy phase 1: BRAF-NRS scale validation cohort. A consecutive cohort of 70 PsA patients was recruited to complete the 3-item BRAF-NRS and the 13-item Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaires, alongside disease activity assessment. All patients also completed the BRAF-NRS questionnaire, 1  day later. Study phase 2: Identifying the potential c...

Authors: Saxena P, Muthu V, Dhooria S, Sehgal IS, Prasad KT, Agarwal R Abstract Methotrexate monotherapy is a common management strategy in rheumatoid arthritis (RA). Treatment with immunosuppression can lead to opportunistic infections such as Pneumocystis jirovecii pneumonia (PJP). The treatment options for PJP include cotrimoxazole, clindamycin-primaquine and dapsone. Though these drugs are generally well tolerated, they can result in potentially severe adverse effects. Sometimes several undesired events may occur in a single patient, reminding us of Murphy's law. Herein, we report a case which exemplifies this ...

We thank Dr. Jolobe for his insightful comments regarding our review “Tuberculosis: a focused review for the emergency medicine clinician” [1,2]. Dr. Jolobe highlighted several conditions that present similarly to tuberculosis (TB), including pleural effusion in a patient with previously diagnosed rheumatoid arthritis and systemic lupus erythematosus, pericardial effusion in a patient with previously diagnosed rheumatoid arthritis and systemic lupus erythematosus, immunoglobulin G4-related pleuropulmonary disease and tuberculous pleurisy, and disseminated tuberculosis in a patient with cryptococcal meningitis [1].
