Construct validity of the hand10 questionnaire in patients with hand osteoarthritis

BackgroundThe Hand10 questionnaire is a short, easy-to-understand, visual questionnaire developed for the functional assessment of upper extremity disorders. It consists of visuals of each item as well as facial expressions that reflect the degree of difficulty during the function. It has been stated that the Hand10 questionnaire is suitable for application in the elderly population due to its stated features. ObjectiveThis study aimed to evaluate the validity of the Hand10 questionnaire in hand osteoarthritis, the prevalence of which increases with age. MethodsPatients filled the Hand10, Disabilities of the Arm, Shoulder, and Hand (DASH), and Australian/Canadian Osteoarthritis Hand Index (AUSCAN) questionnaires, once. Validity of Hand10 was determined with DASH and AUSCAN questionnaires using Pearson Correlation Coefficient analysis. ResultsSixty patients were enrolled in the study. The Hand10 score of the patients was 45.15±25.81; DASH score was 76.31±26.37, and AUSCAN score was 32.75±15.58. The analysis revealed that Hand10 scores showed a positive correlation with DASH scores at a “very good” level (r=0.71; p<0.001; 95% confidence interval (CI) [0.55, 0.82]) and AUSCAN scores at an ”excellent” level (r=0.76; p<0.001; 95% CI [0.63, 0.85]). ConclusionThe Hand10 questionnaire is a valid tool in patients with hand OA. This questionnaire, which consists of ten items and includes pictures that have a positive effect on repeatability, is very practical in evaluating hand function in upper extremity disorders, especially in older age individuals.

Assessment of Neuropathic Pain in Erosive Hand Osteoarthritis.

Background/Objectives: Erosive hand osteoarthritis (EHOA) is an aggressive form of hand osteoarthritis (OA) and a severely disabling condition. Patients affected by OA frequently lament symptoms suggestive of neuropathic pain (NP). The aim of our study was to ascertain the presence and severity of NP in patients with EHOA and correlate its presence with EHOA clinical characteristics. Methods: In this retrospective study, we included all consecutive EHOA patients with NP symptoms who underwent upper limb electroneurography (ENoG) and nerve ultrasound. The presence of NP was screened using the ID pain neuropathic pain-screening questionnaire (ID-Pain). In addition, the following NP questionnaires were also used: Douleur Neuropathique en 4 Questions (DN4), PainDETECT, and Neuropathic Pain Symptom Inventory (NPSI). Moreover, patients completed the Australian/Canadian Osteoarthritis Hand Index (AUSCAN) and Dreiser's algofunctional finger index questionnaires assessing EHOA disease activity. The following clinical and laboratory data were collected: age, sex, BMI, disease duration, intensity of pain (VAS 0-10), painful and swollen joints, and inflammatory indices, as well as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Results: Of the 34 patients studied, 24 (70.6%) presented NP to the ID-Pain questionnaire. According to DN4, 14 (41.2%) patients had NP, while using the PainDETECT questionnaire, 67.6% had NP. Patients with NP were statistically younger and had a higher VAS pain score compared to subjects without NP. The ENoG and median nerve ultrasound were normal in 81% of patients, while four patients had carpal tunnel syndrome. The ID-Pain questionnaire correlated with the number of painful joints (r = 0.48, p = 0.03) and with the AUSCAN questionnaire (r = 0.37, p = 0.05). The DN4 questionnaire correlated with PainDETECT (r = 0.58, p < 0.01). The PainDETECT questionnaire correlated with VAS pain (r = 0.49, p = 0.02), the DN4 questionnaire (r = 0.58, p < 0.01), and AUSCAN (r = 0.51, p = 0.02). The NPSI questionnaire correlated negatively with BMI (r = -0.53, p = 0.01) and positively with the PainDETECT questionnaire (r = 0.49, p = 0.02). Conclusions: Our study revealed that 32% to 70% of EHOA patients exhibited symptoms consistent with NP, with observed variability depending on the questionnaire utilized. Despite patients frequently exhibiting symptoms compatible with NP, only 19% of patients presented alterations on ENoG and ultrasound examinations confirming CTS. This suggests a probable nociplastic component for pain in patients with EHOA, which warrants tailored treatment. In the present study, NP correlated with clinical and functional indices of EHOA.

The use of symptomatic slow-acting drugs for osteoarthritis of the joints of the hands: Accent on microcirculation parameters

The aim of the study – to evaluate the effectiveness of the drug Alflutop (bioactive concentrate of small marine fish), as well as its effect on microcirculation parameters in patients with osteoarthritis (OA) of small joints of the hands.Patients and methods. The study included 80 patients aged 35 to 65 years with OA of small joints of the hands, stage I– II according to Kellgren – Lawrence, with pain ≥40 mm and ≤90 mm on a visual analogue scale (VAS). Subjects were distributed in 1:1 ratio. In the study group (combined therapy) patients received Alflutop according to the standard scheme: 2 ml intramuscularly every other day N 10 and meloxicam 7.5–15 mg per day in the “on demand” mode. The second group (monotherapy) received meloxicam 7.5–15 mg per day N 20. During the observation, the dynamics of joint pain on the VAS scale, the dynamics of the disease on the VAS scale by the patient and the doctor, the functional Dreiser index and AUSCAN (Australian/Canadian Osteoarthritis Hand Index), nailfold capillaroscopy (NFC) with an assessment of the number of capillaries and the number of alterations per 1 mm of the distal row of capillaries were evaluated. The duration of the study was 6 weeks.Results and discussion. By the 35th day of treatment with Alflutop in combination with meloxicam, a statistically significant decrease in pain and functional activity of the disease was found according to the VAS indices, the AUSCAN index (p&lt;0.05) compared with the meloxicam monotherapy group. Microcirculation parameters according to NFC data in the Alflutop and meloxicam group remained stable by the end of the study (p&gt;0.05). In meloxicam monotherapy group, by the 35th day of follow-up, there was a significant increase in the number of altered capillaries by 1 mm of the distal row of the nail (p&lt;0.001).Thus, Alflutop demonstrates clinical efficacy in OA of the joints of the hands (reduces pain, stiffness, improves joint function). In addition, the effect of Alflutop with respect to slowing down microcirculatory disorders is not excluded.

Effectiveness of Ultrasound-guided versus Landmark-based Glucocorticoid Injection in the Treatment of First Carpometacarpal Joint Osteoarthritis

Background: Osteoarthritis is a debilitating degenerative disease more pronounced in elderly affecting many joints. The first carpometacarpal joint (CMC1) is commonly affected. Pain is the major complaint, which can impact patient’s daily activities. Intra-articular glucocorticoid injection can be considered if conservative measures fail and ultrasound guided injection might be superior to the traditional anatomic landmark-guided technique. Objective: The aim of this study is to evaluate the effectiveness of ultrasound-guided versus landmark-based approach to intra-articular CMC1 injection using the Australian Canadian osteoarthritis hand index (AUSCAN). Methods: Adult patients diagnosed with symptomatic CMC1 osteoarthritis who failed conservative measures were enrolled. In this prospective observational cohort study, utilizing a convenience sample, intra-articular corticosteroid injection was administered either by ultrasound-guided technique or landmark-based approach. Pain, stiffness and function in 10-points scale at baseline, 6 and 12 weeks were collected and analyzed using descriptive analysis. Results: There were 33 patients enrolled. Mean age was 63 years, with females making up the majority of participants (n = 28, 84.8%). Mean duration of CMC1 pain was 10 months (SD=2.5) up to the point of receiving the injection. Ultrasound guided injection was performed in 60.6% (n=20), while 39.4% (n=13) had the landmark approach. Both groups achieved a statistically and clinically significant level of change in AUSCAN score at week 6 (P≤ 0.05) but with a recurrence of symptoms at week 12 (P ≤ 0.05). At both intervals the AUSCAN scores were better than baseline (P ≤ 0.05). There was no difference between the two groups regarding baseline pain VAS score (mean ultrasound group= 6.6 vs landmark group= 7.5; P = 0.18). No significant differences were identified between two groups in terms of changes from baseline to 6, 12 and between 6 to 12 weeks in pain, stiffness and hand function (P &gt; 0.05). Conclusion: No difference was found between the ultrasound-guided and landmark-based approaches for CMC1 injection on pain score, stiffness, or function.

Patterns and natural history of hand pain in individuals with symptomatic hand osteoarthritis in a prospective cohort study: A post-hoc analysis of a randomised controlled trial

ObjectiveTo investigate the variation in the distribution and the natural history of hand pain over 6 weeks in individuals with symptomatic hand osteoarthritis. DesignPatient-reported outcome data were collected at baseline and weekly for 6 weeks from community-based participants enrolled in a randomised controlled trial. Participants were grouped based on location of significant pain (Visual Analogue Scale, VAS≥40/100 ​mm) (both carpometacarpal (CMC) and interphalangeal (IP), CMC only, and IP only). ResultsAt baseline, of the 106 participants, 55(51.9 %) had pain in both CMC and IP joints, 28(26.4 %) in IP joints only, and 16(15.1 %) in CMC joint only. Those with CMC and IP pain had significantly higher VAS pain [68.1 (2.6) vs 59.3 (3.5) vs 51.2 (4.7)]; Australian Canadian Osteoarthritis Hand Index, (AUSCAN) pain [290.1 (15.7) vs 225.3 (21.2) vs 237.9 (28.4)], stiffness [57.1 (3.7) vs 44.6 (5.0) vs 32.2 (6.7)] and functional limitation [527.5 (30.9) vs 356.0 (41.7) vs 433.3 (55.7)]; and pain sensitization [PainDETECT score 11.1 (1.1) vs 8.1 (1.8) vs 5.8 (1.9)] compared to those with IP or CMC only pain, respectively. All groups showed improvement in outcomes over 6 weeks without significant inter-group differences. ConclusionIn a population with significant hand pain, pain in both CMC and IP joints was most common and identified a more severe phenotype than pain in IP or CMC only with higher pain, more functional limitation and pain sensitization. These data have the potential to inform clinical management of patients with hand pain and patient selection in clinical trials.

Colchicine is an effective therapeutic agent in erosive hand osteoarthritis

Background/Aim: The efficacy of colchicine has been assessed in hand osteoarthritis; however, no studies have investigated its use in the more severe subtype of hand osteoarthritis, known as erosive hand osteoarthritis (EHOA). This retrospective cohort study investigated whether colchicine therapy could provide symptomatic relief and improve inflammation markers in patients with EHOA. Methods: The study included a total of 43 EHOA patients using colchicine (2×0.5 mg) + paracetamol (3×500 mg) daily (colchicine group) and 43 EHOA patients using only paracetamol (3×500 mg) (standard therapy group). Both groups were evaluated for various parameters. Results: The groups were similar in terms of age, sex distribution, and other sociodemographic variables. The decreases in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels from baseline were significantly greater in the colchicine group (P&lt;0.001). Additionally, the visual analog scale (VAS) and Australian Canadian Osteoarthritis Hand Index (AUSCAN) scores, which include pain, stiffness, function, and total score, were significantly better in the colchicine group at 3 months compared to the standard therapy group (P&lt;0.001). Furthermore, although both groups showed significant improvements in these parameters, the amount of improvement was significantly greater in the colchicine group (P&lt;0.001). Conclusion: The combined use of colchicine and paracetamol improved CRP and ESR levels, VAS score, and all AUSCAN scores in patients with EHOA. Moreover, these benefits were significantly greater than standard therapy with paracetamol alone. Colchicine appears to be an effective therapeutic agent in the treatment of EHOA.

Associations between pain sensitization and measures of physical function in people with hand osteoarthritis: Results from the Nor-Hand study

To examine whether pain sensitization is associated with hand and lower extremity function in people with hand osteoarthritis (OA) in the Nor-Hand study. Pain sensitization was assessed by pressure pain thresholds (PPTs) and temporal summation (TS). Hand function was assessed by Australian/Canadian Osteoarthritis Hand Index (AUSCAN) (range: 0-36), grip strength and Moberg pick-up test, and lower extremity function was assessed by Western Ontario and McMaster Universities Osteoarthritis Index (range: 0-68), 30-s chair stand test, and 40-m walk test. We examined whether sex-standardized PPT and TS values were cross-sectionally associated with measures of physical function using linear regression analyses. Beta coefficients were presented per sex-specific standard deviation of PPT and TS. The mediating effect of pain was examined by causal-inference based mediation analysis. In 206 participants, higher PPTs at/near the hand, indicative of less peripheral and/or central pain sensitization, were associated with greater grip strength and better self-reported hand function (beta for PPT at finger joint on AUSCAN function: -1.41, 95% CI -2.40, -0.42). Higher PPTs at/near the hand, near the knee and at trapezius were associated with lower extremity function, although not statistically significant for all outcomes. Self-reported pain severity mediated the effect of PPT on self-reported function. TS was not associated with hand or lower extremity function. Peripheral sensitization, and possibly central sensitization, was associated with impaired function. Effects of PPTs on self-reported function were mediated by self-reported pain, whereas there might be a direct effect of sensitization or effects through other mediators on performance-based function.

Effect of 6-week treatment with topical betamethasone dipropionate in patients with symptomatic hand osteoarthritis: A randomized double-blind, placebo-controlled trial

ObjectiveTo examine the efficacy and safety of topical corticosteroid over 6 weeks in patients with symptomatic hand osteoarthritis. DesignIn a randomized, double-blind, placebo-controlled trial, community-based participants with hand osteoarthritis were randomly assigned (1:1) to topical Diprosone OV (betamethasone dipropionate 0.5 ​mg/g in optimised vehicle, n=54) or placebo (plain paraffin, n=52) ointment to painful joints 3 times daily for 6 weeks. Primary outcome was pain reduction [assessed by 100 ​mm visual analogue scale (VAS)] at 6 weeks. Secondary outcomes included changes in pain and function using the Australian Canadian Osteoarthritis Hand Index (AUSCAN), Functional Index for Hand Osteoarthritis (FIHOA), and Michigan Hand Outcomes Questionnaire (MHQ) at 6 weeks. Adverse events were recorded. ResultsOf 106 participants (mean age 64.2 years, 85.9% female), 103 (97.2%) completed the study. Change in VAS at 6 weeks was similar in the Diprosone OV and placebo groups (−19.9 vs. −20.9, adjusted difference 0.6, 95% CI -8.9 to 10.2). There were no significant between-group differences in change in AUSCAN pain [adjusted difference 25.8 (−16.0 to 67.5)], AUSCAN function [21.2 (−55.0 to 97.4)], FIHOA [-0.1 (−1.7 to 1.5)], or MHQ [-1.2 (−6.0 to 3.6)]. Incidence of adverse events was 16.7% in Diprosone OV and 19.2% in placebo group. ConclusionsTopical Diprosone OV ointment, although well-tolerated, was no better than placebo in improving pain or function over 6 weeks in patient with symptomatic hand osteoarthritis. Future studies should consider examining joints with synovitis and whether delivery approaches enhancing transdermal penetration of corticosteroids into joints are effective in hand osteoarthritis.

Effect of Moringa oleifera Extract on Inflammatory Status in Cancer Patients with Aromatase-Induced Arthralgia

BACKGROUND: Aromatase inhibitor therapy is commonly used for breast cancer patients with characteristics of positive estrogen and progesterone receptors test without metastases. Thus, this kind of therapy generally gives side effects of aromatase-induced arthralgia (AIA). Moringa oleifera has a strong anti-inflammatory substance that has the potential to reduce inflammation and pain in a patient with AIA. AIM: This study aims to assess the effect of M. oleifera extract administration on pain response and inflammatory status in breast cancer with aromatase inhibitor-induced arthralgia patients. METHODS: Forty-two patients breast cancer patients with estrogen and progesterone receptor-positive in Dr. Kariadi General Hospital were assessed for pain response and inflammatory status before and after the treatment with M. oleifera leaf extract for one month. Assessment of pain response is using the Australian Canadian osteoarthritis hand index (AUSCAN) questionnaire and inflammation is measured by ANA serum level. This study is experimental with two parallel pre-test and post-test group. RESULTS: In the treatment group, there was a significant decrease of the AUSCAN score 13.5 ± 5.11 (p ≤ 0.001), while in the control group, there was an increase in the AUSCAN score 2.7 ± 4.96 (p = 0.022). In the measurement of ANA serum level, a significant decrease of the treatment group found 0.3 ± 0.40 (p ≤ 0.001). CONCLUSIONS: Moringa oleifera extract can help reduce pain response and inflammatory status of patients with chronic inflammation as an additional therapy.

Patients with clinically diagnosed hand OA not fulfilling the ACR classification criteria are in an earlier disease phase and more often have thumb base OA

ObjectiveTo investigate the performance of the American College of Rheumatology (ACR) classification criteria for hand osteoarthritis. DesignLongitudinal data up to four years from a cohort of consecutive patients with primary hand osteoarthritis diagnosed by their rheumatologist (Hostas study) were used to classify presence or absence of hand osteoarthritis according to the 1990 ACR criteria (traditional format: one major and 4 minor ACR criteria) (ACR+/ACR−). Demographics, Australian/Canadian osteoarthritis hand index (AUSCAN) pain and function were obtained. Hand radiographs were scored according to Kellgren-Lawrence; radiographic osteoarthritis was defined as Kellgren-Lawrence ≥2 in ≥1 CMC1 joint or ≥2 DIP/PIP/MCP joints. ResultsOf 538 patients (mean age 61 years, 86.1% women) 485 (90.1%) fulfilled ACR criteria at baseline. Except for the minor criterion swelling of <3 MCP joints, all criteria differed between the groups. ACR− patients were younger, with higher BMI, a shorter time since diagnosis, and less bony enlargements, joint deformities and radiographic osteoarthritis, except for radiographic CMC1 osteoarthritis which was seen more often in ACR− patients. No difference in AUSCAN pain or function was seen between ACR− versus ACR+ patients. After follow-up 37/53 (69.8%) converted to ACR+, 2/53 (3.8%) did not, and 14/53 (26.4%) were lost to follow-up. ConclusionsIn clinical practice the majority of patients fulfill the ACR classification criteria, but those in an earlier disease phase, with less signs of hand osteoarthritis or with primarily thumb base osteoarthritis are less likely to fulfill them. New classification criteria also including earlier disease stages and with attention for hand osteoarthritis subtypes are required.

Efficacy and safety of acupuncture for hand osteoarthritis: study protocol for a multi-center, randomized, sham-controlled clinical trial

BackgroundHand osteoarthritis (OA) is a prevalent disorder in the general population. Patients with hand OA often report symptoms of pain, stiffness, and functional limitations, which cause clinical burden and impact on quality of daily life. However, the efficacy of current therapies for hand OA is limited. Other therapies with better effects and less adverse events are in urgent need. Acupuncture is well known for analgesia and has been proved effective in treating basal thumb joint arthritis. This study aims to clarify the efficacy and safety of acupuncture treatment for clinical symptomatic improvement of hand OA.MethodsThis will be a sham-controlled, randomized, multi-center clinical trial. A total of 340 participants will be recruited and randomly allocated to either traditional acupuncture group or sham acupuncture group. All participants will receive 12 treatment sessions over 4 weeks and 2 follow-up assessments in the following 3 months at week 8 and week 16. The primary outcome will be the proportion of responders at week 5. Secondary outcomes will include visual analog scale, Australian Canadian Osteoarthritis Hand Index, Functional Index for hand OA, the number of symptomatic joints, hand grip strength and pinch strength, global assessment, the World Health Organization Quality of Life abbreviated version and expectations. Safety will be evaluated during the whole process of the trial. All outcomes will be analyzed following the intention-to-treat principle.DiscussionThis prospective trial will provide high-quality evidence on evaluating the efficacy and safety of acupuncture treatment for hand OA. Results of this trial might contribute in offering a new option to clinical recommendations.Trial registration ClinicalTrials.gov Identifier: NCT05267093. Registered 23 February 2022.

Identification of Symptom Phenotypes of Hand Osteoarthritis Using Hierarchical Clustering: Results From the DIGICOD Cohort.

We aimed to delineate phenotypes in hand osteoarthritis (HOA) based on cardinal symptoms (pain, functional limitation, stiffness, and aesthetic discomfort). With data from the Digital Cohort Design (DIGICOD), we performed a hierarchical agglomerative clustering analysis based on Australian/Canadian Osteoarthritis Hand Index (AUSCAN) subscores for pain, physical function, stiffness, and visual analog scale for aesthetic discomfort. Kruskal-Wallis and post hoc analyses were used to assess differences between clusters. Among 389 patients, we identified 5 clusters: cluster 1 (n=88) and cluster 2 (n=91) featured low and mild symptoms; cluster 3 (n=80) featured isolated aesthetic discomfort; cluster 4 (n=42) featured a high level of pain, stiffness, and functional limitation; and cluster 5 (n=88) had the same features as cluster 4 but with high aesthetic discomfort. For clusters 4 and 5, AUSCAN pain score was >41 of 100, representing only one-third of our patients. Aesthetic discomfort (clusters 3 and 5) was significantly associated with erosive HOA and a higher number of nodes. The highly symptomatic cluster 5 was associated but not significantly with metabolic syndrome, and body mass index and C-reactive protein level did not differ among clusters. Symptom intensity was significantly associated with joint destruction as well as with physical and psychological burden. Patients' main expectations differed among clusters, and function improvement was the most frequent expectation overall. The identification of distinct clinical clusters based on HOA cardinal symptoms suggests previously undescribed subtypes of this condition, warranting further study of biological characteristics of such clusters, and opening a path toward phenotype-based personalized medicine in HOA.

Determination and characterization of patient subgroups based on pain trajectories in hand osteoarthritis.

To investigate pain, pain trajectories and their determinants in hand osteoarthritis (OA). Data from the HOSTAS (Hand OSTeoArthritis in Secondary care) consisting of consecutive hand OA patients were used. Australian Canadian Osteoarthritis Hand Index (AUSCAN) pain was measured yearly for four years. Patients with complete AUSCAN at ≥2 time points were eligible for longitudinal analysis. Associations between variables of interest and baseline AUSCAN pain were investigated with linear regression. Development of pain over time was modelled using latent class growth analysis (LCGA). Associations of LCGA classes with variables of interest were analysed using multinomial logistic regression adjusted for baseline pain. A total of 484/538 patients [mean (s.d.) age 60.8 (8.5) years, 86% women, mean (s.d.) AUSCAN pain 9.3 (4.3)] were eligible for longitudinal analysis. Sex, marital and working status, education, disease duration and severity, anxiety and depression scores, lower health-related quality of life (HR-QoL), specific illness perceptions and coping styles were associated with baseline pain. LCGA yielded three classes, characterized by average pain levels at baseline; average pain remained stable over time within classes. Classes with more pain were positively associated with BMI, tender joint count, symptom duration, hand function scores and depression scores, negatively with physical HR-QoL, and education level. Baseline pain was associated with patient and disease characteristics, and psychosocial factors. LCGA showed three pain trajectories in hand OA patients, with different baseline pain levels and stable pain over time. Classes were distinguished by BMI, education level, disease severity, depression and HR-QoL.

Prolonged morning stiffness is common in hand OA and does not preclude a diagnosis of hand osteoarthritis

Prolonged morning stiffness (>60min) is considered a symptom of inflammatory arthritis, but has a poor discriminative ability. Knowledge about morning stiffness in patients with hand osteoarthritis (OA) is lacking. We therefore studied morning stiffness in patients with hand OA. Patients with primary hand OA according to their treating rheumatologist in the Hand OSTeoArthritis in Secondary care (HOSTAS) cohort were studied. Severity of morning stiffness was examined with Australian/Canadian hand OA index (AUSCAN) and presence and duration of morning stiffness were examined with a standardized questionnaire. Association of patient and disease characteristics with prolonged morning stiffness (>60min) were analyzed with logistic regression. In total 519 of 538 patients had available data about duration of morning stiffness, of whom 89 (17%) had prolonged morning stiffness. Severity of stiffness was mild in 158 of 525 (30%), intermediate in 194 (37%), severe in 97 (18%) and extreme in 19 (4%) patients. Patients with prolonged morning stiffness reported more pain, worse physical function and had a reduced mental and physical quality of life. Patients with prolonged morning stiffness also had more severe radiographic disease, although the association did not reach statistical significance. Prolonged and severe morning stiffness are frequently present in patients with hand OA. Patients with these symptoms report more pain in general and have a lower quality of life than patients that do not report these symptoms. Prolonged morning stiffness does not preclude a diagnosis of hand OA.

Efficacy of corticosteroids for hand osteoarthritis - a systematic review and meta-analysis of randomized controlled trials

BackgroundThere is some evidence that corticosteroids may have a beneficial effect in hand osteoarthritis. We examined the efficacy of corticosteroids on symptoms and structural outcomes in hand osteoarthritis.MethodsOvid MEDLINE, Embase and Cochrane Central Register of Controlled Trials were searched from inception to October 2021 for randomized controlled trials investigating the efficacy of corticosteroids in hand osteoarthritis. Two authors independently screened records, extracted data, and assessed risk of bias using the RoB 2 tool. Standardized mean difference (SMD) or mean difference (MD) was calculated, and random-effects meta-analyses were performed.ResultsOf 13 included trials, 3 examined oral corticosteroids and clinical outcomes in any hand joints, 9 examined intra-articular injection of corticosteroids and clinical outcomes at the first carpometacarpal joint and one in the interphalangeal joints. In meta-analysis, oral corticosteroids reduced pain (SMD -0.53, 95% CI -0.79 to -0.28) and improved stiffness (MD -5.03, 95% CI -9.91 to -0.15; Australian Canadian Osteoarthritis Hand Index stiffness subscale) and function (SMD -0.37, 95% CI -0.63 to -0.12) at 4-6 weeks. However, there was no significant persistent effect on pain and function at 3 months which was 6-8 weeks after study medication was stopped. There was no significant effect of intra-articular corticosteroids on pain or function at 4-6 weeks or over 3-12 months in first carpometacarpal osteoarthritis. Two trials evaluated joint structure at 4-6 weeks: one study showed oral corticosteroids reduced synovial thickening, neither showed an effect on synovitis.ConclusionsThere was low-certainty evidence for a medium effect of oral corticosteroids on pain relief and stiffness improvement and small-to-medium effect on functional improvement at 4-6 weeks, with no significant effect for intra-articular corticosteroids. Corticosteroids had no significant effect on any outcomes over longer term (3-12 months) off treatment. No trials examined the effect of corticosteroids on disease progression. The role of corticosteroids in hand osteoarthritis is limited.

A Telehealth-Delivered Tai Chi Intervention (TaiChi4Joint) for Managing Aromatase Inhibitor-Induced Arthralgia in Patients With Breast Cancer During COVID-19: Longitudinal Pilot Study.

BackgroundEstrogen receptor–positive breast cancer is the most common type of breast cancer in postmenopausal women. Aromatase inhibitors (AIs) are the endocrine therapy of choice recommended for these patients. Up to 50% of those treated with an AI develop arthralgia, often resulting in poor adherence and decreased quality of life.ObjectiveThe study is a single-arm longitudinal pilot study aiming to evaluate the safety, feasibility, acceptability, and potential efficacy of TaiChi4Joint, a remotely delivered 12-week tai chi intervention designed to relieve AI-induced joint pain.MethodsWomen diagnosed with stage 0-III breast cancer who received an AI for at least 2 months and reported arthralgia with a ≥4 score on a 0 to 10 scale for joint pain were eligible for study enrollment. Participants were encouraged to join tai chi classes delivered over Zoom three times a week for 12 weeks. Program engagement strategies included using a private Facebook study group and a Box cloud for archiving live class recordings. The program uses SMS text messaging and emails with periodic positive quotes and evidence-based information on tai chi for facilitating community bonding and class attendance. Participants were invited to complete the following assessments at baseline and at 1-, 2-, and 3-month intervals from study enrollment: Brief Pain Inventory, Western Ontario and McMaster University Osteoarthritis Index (WOMAC), The Australian Canadian Osteoarthritis Hand Index (AUSCAN), Fatigue Symptom Inventory, Hot Flash Related Daily Interference Scale (HFRDIS), Pittsburgh Sleep Quality Index (PSQI), and Center for Epidemiological Studies–Depression (CES-D).ResultsA total of 55 eligible patients were invited to participate, and 39 (71%) consented and completed the baseline assessments. Participants attended 61% (median) of the suggested classes, with no tai chi–related adverse events reported. Of the 39 participants, 22 completed the 3-month follow-up assessment with a 56% retention rate. Study participants reported improvement from baseline compared to 3 months as follows (paired t test): Brief Pain Inventory (P<.001), AUSCAN pain subscale (P=.007), AUSCAN function subscale (P=.004), Fatigue Symptom Inventory (P=.004) and PSQI (P<.001), and HFRDIS (P=.02) and CES-D (P<.001). In particular, for our primary end point of interest, improvements in hip and knee symptoms, measured by WOMAC’s three subscales, were clinically meaningful and statistically significant when adjusted for multiple comparisons from baseline to 3 months post intervention.ConclusionsThe COVID-19 global pandemic has resulted in the need to rethink how mind-body therapies can be delivered. This study demonstrated the feasibility, acceptability, and potential efficacy of a telehealth-based tai chi intervention for reducing AI-induced arthralgia. The intervention decreased patient-reported pain and stiffness, and improved sleep quality and depressive symptoms. Fully powered, large, telehealth-based tai chi trials for AI-associated arthralgia are needed considering our promising findings.Trial RegistrationClinicalTrials.gov NCT04716920; https://www.clinicaltrials.gov/ct2/show/NCT04716920

The High Clinical Burden of Erosive Hand Osteoarthritis is Associated with Clinical Findings, Pain, and Radiographic Severity

Varying reports exist on the clinical impact of erosive hand osteoarthritis (EHOA) in terms of pain and articular function. Few studies have assessed the association of a patient's clinical features with the presence of more severe radiographic disease. The aim was to evaluate clinical and radiographic characteristics in EHOA comparing with non-erosive (NEHOA); to examine pain and functional impairment between EHOA and NEHOA; and correlate functional impairment with clinical findings, pain, and radiographic severity. Methods62 patients with EHOA and 57 with NEHO were included. Pain was assessed through Visual Analogue Scale (VAS) and Australian/Canadian Osteoarthritis Hand Index (AUSCAN) pain subdomain. Functioning was evaluated with the Health Assessment Questionnaire (HAQ) concerning hand function and AUSCAN. Radiographs were scored with the Kallman scale and subchondral erosions with the Verbruggen–Veys method. Student t-tests were used for comparing quantitative data, chi-squared tests for categorical variables, and Pearson or Spearman tests for assessing correlation. ResultsPatients with EHOA reported significantly higher levels of pain on the VAS and AUSCAN (p<0.01). In EHOA, VAS positively correlated with the HAQ and AUSCAN scales (rho=0.68 and 0.77). In NEHOA, Visual Analogue Scale (VAS) positively and strongly correlated with HAQ and AUSCAN (rho=0.84 and 0.89). Nodes, Kallman score and erosions showed a positive but weak correlation with HAQ and AUSCAN in both groups. ConclusionBoth EHOA and NEHOA participants had functional impairment, but the erosive subtype had higher clinical burden and increased joint damage. This higher clinical burden is attributed mainly to pain.

Telehealth delivered Tai Chi intervention for managing aromatase inhibitor-induced arthralgia in breast cancer patients: TaiChi4Joint during the COVID-19 pandemic a Pilot study.

e12523 Background: Estrogen receptor positive breast cancer (BC) is the most common type of breast cancer in postmenopausal women and aromatase inhibitors (AI) are the endocrine therapy of choice recommended for these patients. Up to 50% of those treated with an AI develop Arthralgia often resulting in poor adherence and decreased quality of life. Methods: This is a single arm longitudinal pilot study aiming to evaluate the safety, feasibility, acceptability and potential efficacy of TaiChi4Joint, a remotely-delivered 12-week Tai Chi intervention designed for the relief of AI-induced joint pain. Women diagnosed with stage 0-III BC who have been receiving an AI for at least 2 months and reporting arthralgia with a ≥ 4 score on a 0-10 scale for joint pain were eligible for study enrollment. Participants were encouraged to join Tai Chi classes delivered over ZOOM three times a week for 12 weeks. Program engagement strategies include the use of a private Facebook study group and box.com cloud for archiving live class recordings. The program utilizes Text messaging and emails with periodic positive quotes and evidence based information on Tai Chi for facilitating community bonding and class attendance. Participants were invited to complete the following assessments online at baseline, 1, 2 and 3 months intervals from study enrollment: Brief Pain Inventory (BPI), Western Ontario and McMaster University Osteoarthritis index (WOMAC), The Australian Canadian Osteoarthritis Hand Index (AUSCAN), Fatigue Symptom Inventory (FSI), Hot Flash Related Daily Interference Scale (HFRDIS), Pittsburg Sleep Quality Index (PSQI) and Center for Epidemiological Studies Depression (CES-D). Results: 55 eligible patients were invited to participate and 39 consented and completed the baseline assessments. 61% (median) Participants attended the classes, with no Tai Chi related adverse events reported. 22 of the 39 participants completed the 3-month follow up assessments with a 56% retention rate. Study participants reported improvement from baseline compared to 3 month as follows: For BPI ( P = .000), AUSCAN pain subscale ( P =.000), AUSCAN function subscale for 35 patients ( P = .000), WOMAC ( P = .000), CES-D ( P = 0.001), FSI ( P = 0.00) and PSQI ( P = .000). However HFRDIS improved in 11 patients ( P = 0.00) for the other 22 patients (P = 0.154). Conclusions: The COVID-19 global pandemic has resulted in the need to rethink how mind-body therapies can be delivered. This study demonstrated the feasibility, acceptability, and potential efficacy of a Telehealth based Tai Chi intervention for reducing AI-induced arthralgia. The intervention decreased patient reported pain, stiffness and improved sleep quality and depressive symptoms. With our promising findings, larger telehealth based trials of Tai Chi for AI-associated arthralgia are needed. Clinical trial information: NCT04716920.

Pharmacological use of gamma-aminobutyric acid derivatives in osteoarthritis pain management: a systematic review

BackgroundPain is the major complication of osteoarthritis (OA) patients and is a decisive symptom for medical intervention. Gamma-aminobutyric acid (GABA) derivatives are optional painkillers but not widely used in pain management of OA patients. We synthesized the efficacy and safety of GABA derivatives for OA pain management.MethodsWe searched Medline, Cochrane CENTRAL, Embase, and ClinicalTrals.gov from inception to 13 October 2021 and included randomized controlled trials (RCTs) comparing the efficacy and safety of GABA derivatives with placebo or standard control in OA pain management. Two independent reviewers extracted data and assessed these studies for risk of bias using Cochrane Collaboration’s tool for RCT.ResultsIn total, three eligible RCTs (n = 3) meeting the eligibility criteria were included. Among these RCTs, one focused on hand OA pain management, while two RCTs focused on knee OA. In hand OA, pregabalin reduced numerical rating scale (NRS) score and the Australian/Canadian Osteoarthritis Hand Index (AUSCAN) pain score significantly compared with placebo, and caused 55 AEs. In knee OA, pregabalin reduced visual analogue scale (VAS) score and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score significantly with no recorded adverse event (AE). Meanwhile, in knee OA, gabapentin reduced both VAS score and WOMAC pain score compared with acetaminophen and caused 9 AEs.ConclusionsGABA derivatives seem to be effective and safe in OA pain management. However, future researches with large sample size are needed to further prove the efficacy of GABA derivatives in OA pain control.Trial registration: CRD42021240225.

Topical corticosteroid for treatment of hand osteoarthritis: study protocol for a randomised controlled trial

BackgroundHand osteoarthritis is a common and disabling chronic joint disease with a lack of effective therapies. Emerging evidence suggests the role of local inflammation in causing pain in hand osteoarthritis. Corticosteroids are potent anti-inflammatory drugs used in many rheumatic diseases. The aim of this randomised, double-blind, placebo-controlled trial is to determine whether topical corticosteroid reduces pain over 6 weeks in patients with hand osteoarthritis.MethodsOne hundred participants with hand osteoarthritis will be recruited from the community in Melbourne, Australia, and randomly allocated in a 1:1 ratio to receive either topical Diprosone OV or placebo ointment administered 3 times daily on the painful hand joints for 6 weeks. The primary outcome is pain reduction (assessed by 100 mm visual analogue scale) at 6 weeks. The secondary outcomes include changes in pain and function assessed using Functional Index for Hand Osteoarthritis, Australian Canadian Osteoarthritis Hand Index, Michigan Hand Outcomes Questionnaire, and tender and swollen joint count at 6 weeks. Adverse events will be recorded. The primary analysis will be by intention to treat, including all participants in their randomised groups.DiscussionThis study will provide high-quality evidence to determine whether topical corticosteroid reduces pain over 6 weeks in patients with hand osteoarthritis, with major clinical and public health importance by informing clinical practice guidelines for the management of hand osteoarthritis and reducing the burden of the disabling disease.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12620000599976.
