RESUMO

Immune mediated inflammatory diseases (IMIDs) have similarities in pathophysiology and treatment. Not much is known, however, about health-related quality of life (HR-QoL) in IMIDs. We assessed and compared HR-QoL, using the validated EuroQoL 5-dimensions 5-levels questionnaire, in an observational cohort comprising 530 patients (67.5% female, mean age 49 years (95% CI 35.9-50.9), mean disease duration 31.0 months (95% CI 27.2-34.8)), with the following IMIDs: connective tissue diseases (32.6%), uveitis (20.8%), inflammatory arthritis (17.7%), psoriasis (15.5%), vasculitis (6.2%), primary antiphospholipid syndrome (4.2%), and autoinflammatory diseases (2.8%). Patients used either no anti-inflammatory therapy (31.5%), monotherapy (28.7%), or a combination of anti-inflammatory drugs (39.8%). The mean HR-QoL utility score was 0.75 (95% CI 0.72-0.78). Multinominal logistic regression analysis showed a statistically significant association between a very low HR-QoL (utility score (<0.70)) and female sex, rheumatological IMID or psoriasis, smoking or having smoked in the past, and current biological disease modifying anti-rheumatic drugs use.

RESUMO

BACKGROUND: Immune checkpoint inhibitors, approved for the treatment of various types of cancer, are known to cause a unique spectrum of side effects, including acute kidney injury (AKI). The aim of this study was to describe the incidence, risk factors, renal outcomes, and mortality of AKI in patients receiving checkpoint inhibitors. METHODS: Patients receiving checkpoint inhibitors between January 2013 and May 2020 at the University Medical Center Utrecht, the Netherlands, were identified using the Utrecht Patient Oriented Database. AKI was defined as an increase in serum creatinine of ≥1.5 times the baseline value, based on the Kidney Disease: Improving Global Outcomes criteria. Cox proportional hazard regression analysis was used to assess risk factors for AKI and to evaluate the relationship between AKI and mortality. Persistent renal dysfunction was diagnosed in AKI patients with a final serum creatinine measurement of >1.3 times the baseline value. RESULTS: Among 676 patients receiving checkpoint inhibitors, the overall incidence of AKI was 14.2%. Baseline variables independently associated with AKI were a gynecologic malignancy, monotherapy with ipilimumab, and the use of a diuretic, angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker, or proton pump inhibitor at baseline. AKI was checkpoint inhibitor-associated in one third of all patients with AKI. Checkpoint inhibitor-associated AKI was mostly low-grade, occurred a median of 15 weeks after checkpoint inhibitor initiation, and resulted in persistent renal dysfunction in approximately 40% of the patients. Patients with all-cause AKI had a twofold increased mortality risk, but checkpoint inhibitor-associated AKI was not associated with increased mortality. CONCLUSIONS: In this study, patients receiving checkpoint inhibitors frequently developed AKI due to various etiologies. AKI directly related to the effect of checkpoint inhibitor toxicity did not increase mortality. However, AKI not related to the effect of checkpoint inhibitor toxicity was associated with increased mortality.

RESUMO

In osteoarthritis (OA), cartilage degradation is accompanied by subchondral bone changes. The pathogenesis and physiology of bone changes in OA are still unclear. The changes in subchondral bone architecture and cartilage damage were compared in differently induced experimental models of OA. Experimental OA was induced bilaterally by anterior cruciate ligament transection (ACLT) or by cartilage trauma (Groove model); bilateral sham surgery served as control. Lysylpyridinoline (LP, bone resorption) and C-telopeptide of type II collagen (CTX-II, cartilage breakdown) were measured over time. At 20 weeks after surgery, the subchondral cortical plate and trabecular bone of the tibia were analyzed by micro-computed tomography (microCT) and cartilage degeneration was analyzed histologically and biochemically. In both models, cartilage degeneration and cortical subchondral plate thinning were present. CTX-II levels were elevated over time in both models. Subchondral trabecular bone changes were observed only in the ACLT model, not in the Groove model. Correspondingly, LP levels were elevated over time in the ACLT model and not in the Groove model. Interestingly, the trabecular bone changes in the ACLT model were extended to the metaphyseal area. The early decrease in plate thickness, present in both models, as was cartilage damage, suggests that plate thinning is a phenomenon that is intrinsic to the process of OA independent of the cause/induction of OA. On the other hand, trabecular changes in subchondral and metaphyseal bone are not part of a common pathway of OA development and may be induced biomechanically in the destabilized and less loaded ACLT joint.

RESUMO

In studies aimed at local treatment of experimental osteoarthritis (OA) it is optimal to have an internal (untreated) OA control. Such an approach excludes interanimal variation, and allows paired statistical evaluation of treatment efficacy. For this purpose, we developed and characterized a bilateral version of the canine Groove model. We hypothesized that the bilateral version of the canine Groove model would show consistent and clear development of features of OA similar to those found in the unilateral version. In six Beagle dogs, grooves were surgically made in the articular cartilage of the femoral condyles of both knee joints. Six additional dogs underwent bilateral sham surgery. The degree of OA was quantified 20 weeks after surgery and was compared in retrospect to 23 animals that undergone the same procedure in a single knee joint with the contralateral knee serving as a non-OA control. Bilateral groove surgery resulted in OA. This was based on the observed ineffective repair response in which an increase in proteoglycan synthesis, a diminished retention of these newly formed proteoglycans, and an enhanced loss of resident proteoglycans resulted in a decreased cartilage proteoglycan content. These biochemical effects were corroborated by clear histological features of OA. All these effects were found in femor as well as in the (surgically untouched) tibia. Interestingly, features of OA were slightly more severe in the bilateral model than in the unilateral variant. The bilateral canine Groove model showed consistent and clear development of features of OA, comparable to the unilateral model.

RESUMO

OBJECTIVE: Recently a new canine model of osteoarthritis (OA; the 'groove' model) has been described. This model is based on surgically applied mechanical damage of the articular cartilage followed by transient forced loading of the affected joint. Ten weeks after surgery this model shows characteristics of OA, mimicking human OA. To establish whether the observed characteristics of degeneration in this model represent the surgically applied damage, or are the results of progressive features of OA, we evaluated this 'groove' model shortly after surgery. METHODS: In 20 female Beagle dogs, articular cartilage of the weight-bearing areas of the femoral condyles in the right knee was damaged without affecting the underlying bone. After surgery dogs were let out on a patio 5 days/week for 4 h/day. The dogs were forced to load the experimental joint by fixing the contralateral control limb to the trunk 3 days/week. The severity of OA was evaluated at 3 (n = 10) or 10 weeks (n = 10) after surgery. Synovial inflammation, cartilage damage and cartilage matrix turnover were determined. RESULTS: Ten weeks after surgery osteoarthritic features were found, as described previously. Proteoglycan (PG) synthesis, percentage release of newly formed PG, and that of total amount of PG were enhanced, whereas PG content was significantly diminished (all P < 0.05). Importantly, 3 weeks after surgery these characteristics of OA were not yet evident. CONCLUSIONS: The present results clearly show that the characteristics observed 10 weeks after induction of joint degeneration in the groove model are not just the expression of the surgically applied damage but are the result of progressive features of (experimental) OA.

RESUMO

OBJECTIVE: Cartilage of young but skeletally mature dogs is more susceptible to blood-induced damage than that of old dogs. The aim of the present study was to investigate whether cartilage of skeletally immature individuals is even more adversely affected by exposure to blood than that of mature individuals, as suggested by clinical practice experience with humans. METHODS: Right knees of 3 groups of 6 beagle dogs (skeletally immature, young mature, and old animals) were injected with autologous blood on days 0 and 2. On day 4, cartilage matrix proteoglycan turnover (content, synthesis, and release), synovial inflammation, and cartilage-destructive properties of the synovial tissue were determined and compared with those of the left uninjected control knees. RESULTS: Subsequent to intraarticular bleeding, cartilage proteoglycan content decreased in an age-dependent manner, with the largest decrease occurring in cartilage of immature animals. Proteoglycan synthesis per cell also decreased in an age-dependent manner, with the largest decrease occurring in the immature animals. Cartilage proteoglycan release increased in all 3 groups, but the decrease was not age dependent. Interestingly, immature animals showed a large increase in cartilage DNA content upon exposure to blood, whereas mature animals did not. Histologic analysis showed a mild synovitis in animals of all ages, but catabolic inflammatory activity was found only in immature animals. CONCLUSION: Joints of skeletally immature dogs appeared to be more susceptible than joints of mature dogs to the adverse effects of a joint hemorrhage. These data suggest that for humans, specifically young children are at risk for joint damage after a joint hemorrhage.

RESUMO

OBJECTIVE: To investigate the effect of a limited number of experimental joint bleedings, combined with loading of the affected joint, on the development of progressive degenerative joint damage. METHODS: The right knee of 8 mature beagle dogs was injected with freshly collected autologous blood 3 times per week for 4 weeks, to mimic a limited number of joint hemorrhages occurring over a short period. To ensure loading of the experimental joint, the contralateral control knee of the animals was fixed to the trunk 4 hours per day, 3 days per week. Ten weeks after the last injection, cartilage tissue and synovium were collected from both knees to analyze features of joint degeneration. Cartilage was prepared for analysis of proteoglycan turnover (synthesis, retention, release, and content) and histologic features. Synovium was prepared for histologic analysis. RESULTS: The rate of proteoglycan synthesis was significantly increased, characteristic of degenerative cartilage damage as seen in osteoarthritis. Release of newly formed proteoglycans (as a measure of retention) and total loss of proteoglycans from the cartilage matrix were increased. Cartilage matrix integrity was adversely altered, as shown by histologic damage. Histologic analysis also revealed signs of synovial inflammation. These effects were not observed 10 weeks after the experimental bleedings in joints that did not undergo forced loading. CONCLUSION: Experimental joint bleedings when combined with loading of the affected joint resulted in features of progressive degenerative joint damage, whereas similar joint hemorrhages without joint loading did not. This might reflect a possible mechanism of joint damage in hemophilia.
