Time Effect of Intra-articular Injection With Triamcinolone Hexacetonide and Its Correlations: A Case-Control Prospective 12-Month Study

Efficacy of tumor necrosis factor inhibitor combined with intra-articular injection of triamcinolone acetonide in the treatment of refractory rheumatoid arthritis synovitis: a retrospective study

OBJECTIVE

To investigate whether there is a difference in the efficacy of intra-articular injection of tumor necrosis factor (TNF) inhibitor and triamcinolone acetonide (HA) in rheumatoid arthritis (RA) patients with recurrent synovitis after the first intra-articular injection of HA.

METHODS

RA patients who relapsed 12 weeks after the first HA treatment were enrolled in this study. After joint cavity extraction, recombinant human TNF receptor-antibody fusion protein (TNFR:FC) (25 mg or 12.5 mg) or HA (1 ml or 0.5 ml) was injected then. The changes in the visual analog scale (VAS), joint swelling index, and joint tenderness index before and 12 weeks after reinjection were compared and analyzed. The changes in synovial thickness, synovial blood flow, and fluid dark zone depth before and after reinjection were observed by ultrasound.

RESULTS

Forty-two RA patients were enrolled, including 11 males and 31 females, with an average age of 46.79 ± 12.61 years and an average disease duration of 7.76 ± 5.44 years. After 12 weeks of intra-articular injection of HA or TNFR:FC, the VAS scores were significantly lower than those before treatment (P < 0.01). After 12 weeks of injection, the scores of the joint swelling index and tenderness index in both groups were significantly decreased compared with those before treatment. There was no significant difference in synovial thickness under ultrasound in the HA group before and after injection, while the synovial thickness in the TNFR:FC group was significantly improved after 12 weeks (P < 0.01). After 12 weeks of injection, the grade of synovial blood flow signal in both groups decreased significantly compared with that before treatment, especially in the TNFR:FC group. After 12 weeks of injection, the depth of the liquid dark area under ultrasound decreased significantly in the HA group and TNFR:FC group compared with that before treatment (P < 0.01).

CONCLUSION

Intra-articular injection of a TNF inhibitor is an effective method for the treatment of recurrent synovitis after conventional hormone therapy. Compared with HA treatment, it can reduce synovial thickness. Key Points • Intra-articular injection of a TNF inhibitor is an effective method for the treatment of recurrent synovitis after conventional hormone therapy. • Compared with HA treatment, intra-articular injection of biological agents combined with glucocorticoids can not only relieve joint pain but also significantly inhibit joint swelling. • Compared with HA treatment, intra-articular injection of biological agents combined with glucocorticoids cannot only improve synovial inflammation but also inhibit synovial proliferation. • For the treatment of refractory RA synovitis, biological agents combined with glucocorticoid injection are an effective and safe option.

Musculoskeletal corticosteroid injections: Recommendations of the French Society for Rheumatology (SFR)

Musculoskeletal corticosteroid injections are widely performed, although the exact practice varies greatly due to advances in knowledge and techniques. This justifies updating and drawing up good practice recommendations. Using a consensus model formalized by the French National Authority for Health (HAS) and based on a literature review that resulted in a "white book", 13 recommendations were developed by a group of experts. These recommendations were then sent online to 48 specialists for evaluation, 27 of whom were rheumatologists and 15 of whom were general practitioners. These recommendations were also presented at the 34th annual meeting of the French Society for Rheumatology (SFR) (Paris, December 2021) at a symposium attended by a hundred or so rheumatologists, who voted on these recommendations in person. The results are presented as an overall score out of 10, a median out of 10 and as tertiles. The agreement was excellent for 10 of these 13 recommendations, with mean values of 8.5 to 9.1 out of 10, median values of 9 or 10 out of 10 and agreement of 91.7% to 97.9%, which corresponds to a consensus. The 3 other recommendations were broadly supported but were the subject of more debate. One relates to patient information (mean 7.3/10, median 8/10, upper tertile 72.9%) with discussion about the waiting period. Another related to the summary report (mean 8.4/10, median 9, upper tertile 91.7%) with discussions about its content and the need to specify the lot number of the injected product. The last one related to periprosthetic injections and the need to consult and get approval from a specialist (mean 8.0/10, median 8, upper tertile 83.3%) with mostly the general practitioners having reservations. In all, there is a very strong consensus among the musculoskeletal corticosteroid injection experts and specialists consulted, which justifies them being taken into consideration to improve our daily practice.

Response to treatment with intra-articular triamcinolone hexacetonide and triamcinolone acetonide in oligo articular juvenile idiopathic arthritis

BACKGROUND

Oligo-articular juvenile idiopathic arthritis (Oligo JIA) is the most common subtype of juvenile idiopathic arthritis. Intra-articular corticosteroid (IAC) injection is a mainstay treatment of oligo JIA providing pain relief, improving mobility and preventing further joint destruction in the majority of patients. In 2015, production of triamcinolone hexacetonide (TH) an intra-articular corticosteroid was discontinued in the United States leading to use of triamcinolone acetonide (TA) as an alternative. In this study, we compared response to treatment in children with oligo JIA who underwent therapy with intra-articular TA and TH injection.

METHODS

Our study is a retrospective chart review of children with oligo JIA who were treated with IAC injections with TH between January 2012 and June 2015 and TA between J uly 2015 and December 2018. The two groups were followed at John R. Oishei Children's Hospital of Buffalo and were evaluated for response to treatment, side effects and predictors of response including duration of disease before treatment, erythrocyte sedimentation rate (ESR), and c-reactive protein (CRP). Response to treatment was defined as at least 6 months follow up without evidence of active arthritis in injected joints. Patients were considered to be non-responders if they continued to show active arthritis during their first follow up after joint injection. The primary objective was to evaluate whether there was a significant difference in rate of response between TH and TA.

RESULTS

Forty-nine patients, 38 female and 11 male with oligo JIA were included in the study. The average age was 6.7 years. A total of 111 joints were injected includin g 78 knees, 13 ankles, 9 wrists, 4 hips, 4 elbows, 2 TMJ and one subtalar joint. In the TA group, 49% (29/59) did not show response to injection compared to 27% (14/52) in the TH group. After 6 months, response rates were better for individuals injected with TH compared to TA (73% vs. 51%). In general, response to intra-articular TH was superior to TA with P = .016 using chi-square test of independence. This difference in outcome was not influenced by other variables such as duration of illness before treatment (P value 0.784) or elevated ESR and CRP. No difference in side effects between the two groups were noted.

CONCLUSION

Our results in conjunction with prior published data suggests that TH intra-articular joint injection in oligo JIA is superior to TA, although future controlled trials are necessary for confirmation. An effective, long lasting treatment can have a great impact on the outcome of these children.

The intra-articular administration of triamcinolone hexacetonide in the treatment of osteoarthritis. Its effects in a naturally occurring canine osteoarthritis model

OBJECTIVE

To evaluate the effect of an intra-articular (IA) administration of triamcinolone hexacetonide, compared with saline.

PATIENTS AND METHODS

Forty (N = 40) hip joints were randomly assigned to a treatment group (THG, n = 20, receiving IA triamcinolone hexacetonide) and a control group (CG, n = 20, receiving IA saline). On treatment day (T0), and at 8, 15, 30, 90 and 180 days post-treatment, weight distribution, joint range of motion, thigh girth, digital thermography, radiographic signs, synovial fluid interleukin-1 and C-reactive protein levels were evaluated. Data from four Clinical Metrology Instruments was also gathered. Results were compared Repeated Measures ANOVA, with a Huynh-Feldt correction, Paired Samples T-Test or Wilcoxon Signed Ranks Test. A Kaplan-Meier test was performed to compare both groups, with p<0.05.

RESULTS

Joints were graded as mild (65%), moderate (20%) and severe (15%). Patients of both sexes, with a mean age of 6.5±2.4 years and bodyweight of 26.7±5.2kg, were included. No differences were found between groups at T0. Comparing THG to CG, weight distribution showed significant improvements in THG from 8 (p = 0.05) up to 90 days (p = 0.01). THG showed lower values during thermographic evaluation in the Lt view (p<0.01). Pain and function scores also improved from 30 to 180 days. Increasing body weight, age, and presence of caudolateral curvilinear osteophyte corresponded to worse response to treatment. Results of the Kaplan Meier test showed significant differences between groups, with THG performing better considering several evaluations and scores.

CONCLUSION

THG recorded significant improvements in weight-bearing and in with the considered CMIs, particularly pain scores. Lower thermographic values were registered in THG up to the last evaluation day. Age, sex, and radiographic findings did significantly influenced response to treatment.

Intra-articular Injections With Either Triamcinolone Hexacetonide, Stanozolol, Hylan G-F 20, or a Platelet Concentrate Improve Clinical Signs in Police Working Dogs With Bilateral Hip Osteoarthritis

Objectives: To compare the effect of intra-articular treatment with triamcinolone hexacetonide (TH), stanozolol, hyaluronan, and a platelet concentrate in police working dogs with bilateral hip osteoarthritis (OA). Study Design: Prospective, longitudinal, double-blinded, negative controlled study. Sample Population: Fifty police working dogs with naturally occurring hip OA. Methods: Animals were randomly assigned to a control group (CG, n = 10), TH group (THG, n = 10), platelet concentrate group (PCG, n = 10), stanozolol group (SG, n = 10), and Hylan G-F 20 group (HG). On days 0 (T0), 8, 15, 30, 90, and 180 days post-treatment, weight-bearing distribution was evaluated. In those days, and on days 60, 120, and 150, four clinical metrology instruments were completed. Kaplan-Meier estimators were conducted and compared with the log-rank test. Cox proportional hazard regression analysis was performed to determine treatment survival. Significance was set at p < 0.05. Results: Patients had a mean age of 6.5 ± 2.4 years and body weight of 26.7 ± 5.2 kg. At T0, hips were classified as mild (n = 35), moderate (n = 10), and severe (n = 5), according to the Orthopedic Foundation for Animals grading scheme. No differences were found between groups at that moment considering age, body weight, OFA hip score, and all assessments performed. All treatments improved clinical signs in various OA dimensions in some groups, with a broad effect interval. PCG showed a lower range of variation while maintaining a positive result for more extended periods (p < 0.01 for symmetry index and 0.01 < p < 0.04 in the majority of scores). Breed, age, sex, and OFA grade did not significantly influence response to treatment. Conclusions and Clinical Relevance: This is the first prospective, negative controlled, double-blinded study to compare the effect of a single administration of these IA treatments in dogs with hip OA. HG and PCG recorded more significant improvements throughout the 180-day follow-up. In particular, PCG also registered a lower variation in results, seemingly the best therapeutic option. Nevertheless, improvements were still observed in THG and SG, and these treatment options can be considered, mainly when the first two treatments are not available.
