[PMID: 34782180 DOI: 10.1016/j.semarthrit.2021.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 09/16/2021] [Accepted: 10/18/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To estimate and compare the diagnostic accuracy of magnetic resonance imaging (MRI) and ultrasound, for the prediction of rheumatoid arthritis (RA) in unclassified arthritis (UA). METHODS MEDLINE, Embase and BIOSIS were searched from 1987 to May 2019. Studies evaluating any imaging test in participants with UA were eligible. Reference standards were RA classification criteria or methotrexate initiation. Two authors independently extracted data and assessed validity using QUADAS-2. Sensitivities and specificities were calculated for each imaging characteristic and joint area. Summary estimates with 95% confidence intervals (CI) were estimated where possible. RESULTS Nineteen studies were included; 13 evaluated MRI (n=1,143; 454 with RA) and 6 evaluated ultrasound (n=531; 205 with RA). Studies were limited by unclear recruitment procedures, inclusion of patients with RA at baseline, differential verification, lack of blinding and consensus grading. Study heterogeneity largely precluded meta-analysis, however summary sensitivity and specificity for MRI synovitis in at least one joint were 93% (95% CI 88%, 96%) and 25% (95% CI 13%, 41%) (3 studies). Specificities may be higher for other MRI characteristics but data are limited. Ultrasound results were difficult to synthesise due to different diagnostic thresholds and reference standards. CONCLUSION The evidence for MRI or ultrasound as single tests for predicting RA in people with UA is heterogeneous and of variable methodological quality. Larger studies using consensus grading and consistently defined RA diagnosis are needed to identify whether combinations of imaging characteristics, either alone or in combination with other clinical findings, can better predict RA in this population.

A Pragmatic Application of Ultrasonography for the Assessment of Disease Activity in Patients with Early Inflammatory Arthritis. J Clin Med 2021; 10:jcm10020283. [PMID: 33466710 PMCID: PMC7828798 DOI: 10.3390/jcm10020283] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 01/07/2021] [Accepted: 01/11/2021] [Indexed: 01/13/2023] Open
Abstract
The aim of the study was to examine the usefulness of targeted musculoskeletal ultrasonography (MSUS) in assessing the disease activity of patients with early inflammatory arthritis (EIA). Twenty-eight patients with EIA were enrolled. The MSUS examination of joints with arthritic signs (tenderness or swelling), measurement of 28-joint Disease Activity Score (DAS28), and its components were performed at four-week interval visits until power doppler (PD) US remission was achieved. Various MSUS parameters of grey scale (GS) and PD synovitis were measured. Pearson or Spearman correlation coefficients were determined for the purpose of the study. Data were gathered from a total of 85 visits. The Sum of GS grade correlated better with physical examination findings, while the Sum of PD grade correlated better with serum inflammatory markers and patient global health. However, Global OMERACT-EULAR Synovitis Score (GLOESS), which reflected both PD and GS grades, correlated evenly well with each clinical parameter. In addition, GLOESS correlated best with DAS28 in the overall study population (p < 0.01). Conclusively, our targeted MSUS parameters of arthritic joints, especially sums of semi-quantitative grades of synovitis, could be useful in monitoring patients with EIA.

The changing role of ultrasonography examination in patients with rheumatoid arthritis in light of recent studies. Reumatologia 2020; 58:155-161. [PMID: 32684648 PMCID: PMC7362270 DOI: 10.5114/reum.2020.96676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Accepted: 06/02/2020] [Indexed: 11/23/2022] Open
Abstract
For many years, ultrasonography (US) has been a widely accepted modality used for joint assessment in patients with rheumatoid arthritis (RA). Given the efficacy of present day therapies, there is scepticism whether it is required in the first place. The most recent clinical Targeting synovitis in Early Rheumatoid Arthritis (TaSER) and Clinical Tight Control Therapy (ARCTIC) trials’ results appear to contradict it, yet this does not necessarily mean ultrasound has no place in modern rheumatology. The possibility of detecting inflammation at a subclinical level carries a tremendous predictive value, enabling identification of patients likely to experience an exacerbation in the coming months. Therefore, US should be a part of the decision-making process regarding treatment modification or introduction of any additional interventions, such as glucocorticosteroid injections. The results of the most recent clinical trials do not negate the usefulness of US, but merely suggest that it ought to be used in moderation.

Color fraction as a useful method of imaging synovium vascularization in patients with high activity of rheumatoid arthritis. Reumatologia 2020; 58:42-47. [PMID: 32322123 PMCID: PMC7174790 DOI: 10.5114/reum.2020.93513] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Accepted: 02/20/2020] [Indexed: 01/05/2023] Open
Abstract
Rheumatoid arthritis (RA) is an autoimmune disease with joint inflammation and destruction as the main features that appears with prevalence of 1 to 2% of the general population. Women are three times more likely to suffer from RA than men. Rheumatoid arthritis occurs at any age but commonly over 40-50 years old. In the course of RA each joint may be involved but most frequently the proximal interphalangeal and metacarpophalangeal joints of the hands, wrists, and also small joints of the feet are affected. Symmetrical joint swelling with overgrowth of synovium and hypervascularization confirmed in power Doppler ultrasound imaging are very characteristic for RA. Quantification of vascularization with the color fraction index may be a useful tool to monitor disease activity and in evaluation of inflammation in scientific research. This article aims to present this imaging diagnostic method based on the literature.

Jackson J, Leung D, Burt H. The use of ultrasound to increase the uptake and cytotoxicity of dual taxane and P-glycoprotein inhibitor loaded, solid core nanoparticles in drug resistant cells. ULTRASONICS 2020; 101:106033. [PMID: 31561207 DOI: 10.1016/j.ultras.2019.106033] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 08/02/2019] [Accepted: 09/17/2019] [Indexed: 06/10/2023]
Abstract
The objective of this study was to use ultrasound in combination with nanoparticulate formulations of taxane drugs for an additive approach to overcome multidrug resistance (MDR). Polymeric nanoparticulate formulations containing both chemotherapeutic taxane drugs and a polymeric inhibitor (MePEG17-b-PCL5) of drug resistant proteins have been previously developed in an attempt to overcome MDR in cells. High frequency (>1 MHz) ultrasound has been shown to increase the uptake of cytotoxic drugs in MDR proliferating cells and has been suggested as a different way to overcome MDR, resensitize drug resistant cancer cells and allow for chemotherapeutic efficacy. MDCK-MDR cells were incubated with docetaxel (DTX) or paclitaxel (PTX) loaded, solid core, nanoparticles made from a 50:50 ratio of two diblock copolymers, MePEG114-b-PCL200 and MePEG17-b-PCL5 (PCL200/PCL5). The accumulation of drug in MDCK-MDR cells was measured using radiolabeled drug and the viability of cells was determined using an MTS cell proliferation assay. The effect of ultrasound (4 MHz, 32 W/cm2, 10 s, 25% duty cycle) on drug uptake and cell viability was studied. Using free DTX or PTX, MDCK-MDR cells were killed at sublethal doses of drug with the P-gp inhibitor (MePEG17-b-PCL5) present at a concentration of just 0.006% (m/v) and cell death began after just 3 h of incubation. Using sublethal incubation doses of PTX or DTX in PCL200/PCL5 nanoparticles for 90 min, followed by a second exposure to blank PCL200/PCL5 nanoparticles, cell viability dropped by approximately 60% at 24 h. Drug accumulation increased by 1.43-1.9 fold following five bursts of ultrasound applied at 90 min. Both, increased ultrasound exposure and increased concentrations of blank nanoparticles during the second incubation allowed for increased levels of cell death. The combined use of ultrasound with taxane and P-gp inhibitor loaded polymeric nanoparticles may allow for increased accumulation of drug and inhibitor which may then release both agents inside cells in a controlled manner to overcome drug resistance in MDR cells.
