The effects of a selective bradykinin 1 receptor antagonist, compound A, were evaluated in a canine model of acute inflammatory model of arthritis. Despite detection of the B1 receptor in canine type B synoviocytes using a fluorescent ligand, oral administration of compound A (9 and 27 mg/kg) did not improve weight bearing of dogs injected intra-articularly with IL-1β in a force plate analysis. Analysis of the synovial fluid of IL-1β-treated dogs indicated high levels of bradykinin postchallenge. Excellent exposure, coupled with evidence of the presence of the B1 receptor during an acute inflammatory model of pain, indicates an inability of the receptor to mediate inflammatory pain in canines...

A 3-year-old Labrador Retriever originating from Spain was presented with a left-sided hind limb lameness for several months. The orthopedic examination revealed a pain response when palpating the left tarsal joint. Radiographic and computed tomographic studies showed polyostotic, aggressive osteolytic bone lesions with mild erosive arthritis. The diagnosis of canine leishmaniasis was confirmed by bone biopsy and the detection of the pathogen by PCR. Three weeks after initiation of therapy with allopurinol, the dog presented no signs of lameness...

Fluoroquinolones (FQs) are frequently used for septic arthritis. Increased antibacterial activity has been associated with mammalian cell cytotoxicity that may increase the risk of developing osteoarthritis. This study compared the direct effects of two different FQs, enrofloxacin (Enro) and marbofloxacin (Mar), on normal primary canine chondrocytes and inflammatory-stimulated chondrocytes, in addition to their administration in combination with hyaluronan (HA). Cell viability, cell apoptosis, s-GAG production, and expression patterns of inflammatory, extracellular matrix (ECM) component and protease genes were measured...

The activity of matrix metalloproteinase (MMP)-2 and MMP-9 in synovial fluids (SF) sampled from dogs with joint disorders was investigated by gelatin zymography and densitometry. Pro-MMP-2 showed similar activity levels in dogs with idiopathic polyarthritis (IPA; n=17) or canine rheumatoid arthritis (cRA; n=4), and healthy controls (n=10). However, dogs with cranial cruciate ligament rupture (CCLR; n=5) presented significantly higher pro-MMP-2 activity than IPA and healthy dogs. Meanwhile, dogs with IPA exhibited significantly higher activity of pro- and active MMP-9 than other groups...

Intervertebral disk disease (IVDD) is a major spine disorder in canines that causes neurological dysfunction, particularly in the thoracolumbar area. Analgesic and anti-inflammatory drugs are typically used to reduce nociceptive signals to decrease canine suffering. Bee venom (BV) has been reported to exert anti-inflammatory and analgesic effects. Injection of BV at acupoints has been widely used to treat clinical disorders including inflammation, pain, and arthritis. The current study was intended to determine whether BV injections at acupoints can enhance treatment of canine neurological dysfunction caused by IVDD...

Lesions in canine stifle joints after previous trochleoplasty surgery were documented. In four clinical cases arthrotomies were performed due to stifle pain after previous trochlear deepening procedures. A small area of hyaline cartilage remained in the groove of the stifles in cases where previous wedge trochleoplasties had been performed. All of the stifles had significant areas of eburnation on the axial aspect of the medial trochlear ridge. The stifle joints of a dog that was euthanased due to severe irreversible osteoarthritis were photographed...

Idiopathic polyarthritis (IPA) is a very common inflammatory arthropathy in the dog. Canine IPA is diagnosed mainly by detecting increased number of leukocytes in the synovial fluid (SF), which is easily influenced by glucocorticoid therapy. We obtained 31 SF samples from 24 IPA dogs prior to (n=19) and/or after (n=12) 1 to 10 weeks of glucocorticoid therapy. The SF total protein concentrations of IPA dogs were significantly higher than those of dogs with non-arthritis diseases (n=34) and healthy controls (n=10)...

Evidence-based information of a cause-and-effect relationship between Ehrlichia canis infection and polyarthritis in naturally- or experimentally-infected dogs is currently lacking. The aim of this prospective study was to investigate whether synovial fluid cytological evidence of arthritis could be documented in dogs with acute monocytic ehrlichiosis. Direct synovial fluid cytology smears from eight Beagle dogs experimentally infected with E. canis were examined prior to, and on 21, 35 and 63 days post-inoculation...

BACKGROUND: The temporomandibular joint (TMJ) may be affected unilaterally or bilaterally in the course of juvenile idiopathic arthritis (JIA). Permanent complications involve joint damage or stiffness and disorders in the development of the mandible, such as micrognathia, posterior rotation of the mandible, crowding and protrusion of the front teeth and malocclusion. OBJECTIVES: The aim of the study was the clinical and radiological assessment of TMJ dysfunctions and disorders in the development of the mandible in patients suffering from JIA, depending on the duration of the disease...

CASE DESCRIPTION: Severe lymphocytosis and leukocytosis were detected during examination of a 10-year-old sexually intact male bat-eared fox (Otocyon megalotis) with regionally extensive alopecia. CLINICAL FINDINGS: A CBC revealed severe leukocytosis (39,100 leukocytes/μL) and marked lymphocytosis (90%). A blood smear consisted predominantly of intermediate-sized lymphocytes and few large lymphocytes, with mild to moderate nuclear atypia. These findings were highly suggestive of chronic lymphocytic leukemia (CLL)...

Recent evidence suggest that Bartonella species may cause polyarthritis and lameness in dogs. Canine leishmaniosis (CanL) due to Leishmania infantum is a multi-systemic disease often occurring in association with arthritis. We hypothesized that concurrent Bartonella infection may be a contributing factor for the development of arthritis in dogs with CanL. Hence the primary objective of this study was to investigate the molecular prevalence of Bartonella spp. in dogs with naturally occurring CanL, with or without cytologically documented arthritis...

Osteoarthritis is one of the most common, debilitating, musculoskeletal diseases; 12% associated with traumatic injury resulting in post-traumatic osteoarthritis (PTOA). Our objective was to develop a single impact model with cartilage "injury level" defined in terms of controlled combinations of strain rate to a maximum strain (both independent of cartilage load resistance) to study their sensitivity to articular cartilage cell viability and potential PTOA biomarkers. A servo-hydraulic test machine was used to measure canine humeral head cartilage explant thickness under repeatable pressure, then subject it (except sham and controls) to a single impact having controlled constant velocity V=1 or 100mm/s (strain rate 1...

Fourier transform infrared imaging (FTIRI) combining with principal component regression (PCR) analysis were used to determine the reduction of proteoglycan (PG) in articular cartilage after the transection of the anterior cruciate ligament (ACL). A number of canine knee cartilage sections were harvested from the meniscus-covered and meniscus-uncovered medial tibial locations from the control joints, the ACL joints at three time points after the surgery, and their contralateral joints. The PG loss in the ACL cartilage was related positively to the durations after the surgery...

PRACTICAL RELEVANCE: Osteoarthritis, a degenerative non-inflammatory joint disease, is common in cats, usually causing gradual changes in behavior and lifestyle rather than severe lameness. Inflammatory arthritis occurs much less frequently and is nearly always associated with debilitating lameness. It may have an infectious or immune-mediated cause - but, unlike the canine disease, is much more likely to be infectious in origin. CLINICAL CHALLENGES: Cats with inflammatory joint disease are presented for evaluation of lethargy, anorexia, reluctance to walk or fever...

The major forms of inflammatory canine arthritis are immune-mediated arthritis (IMA) and septic arthritis (SA), although some cases of cruciate disease (CD) are associated with significant levels of synovitis. In this study, the bacteria associated with canine arthritis were identified and mRNA expression levels of Toll-like receptors (TLRs) and pro-inflammatory cytokines determined. Of the 40 synovial fluid samples analysed, bacteria were isolated from 12 samples by culture (2 CD, 10 SA) and detected in 4 samples (3 CD, 1 SA) using culture-independent methods...

Autoinflammatory disease (AID) manifests from the dysregulation of the innate immune system and is characterised by systemic and persistent inflammation. Clinical heterogeneity leads to patients presenting with one or a spectrum of phenotypic signs, leading to difficult diagnoses in the absence of a clear genetic cause. We used separate genome-wide SNP analyses to investigate five signs of AID (recurrent fever, arthritis, breed specific secondary dermatitis, otitis and systemic reactive amyloidosis) in a canine comparative model, the pure bred Chinese Shar-Pei...
