Spontaneous tendon rupture in systemic lupus erythematosus: association with Jaccoud`s arthropathy

Tendon rupture has rarely been described in patients with systemic lupus erythematosus. From observation of three cases of Jaccoud`s arthropathy with tendon rupture, and considering that this arthropathy is more related to an inflammatory process of the tendon sheath than to synovitis per se, the intention of this study was to review the cases of tendon rupture in patients with systemic lupus erythematosus, in the hope of determining the frequency of Jaccoud`s arthropathy associated with this complication. Systematic review using MEDLINE, Scielo and LILACS databases (1966 to 2009) and the following keywords: systemic lupus erythematosus, tendon rupture, Jaccoud`s arthropathy. Secondary references were additionally obtained. Additionally, three Brazilian systemic lupus erythematosus patients who developed tendon rupture are described. Only 40 articles obtained fulfilled the previously established criteria. They were all case reports; the number of cases reported was 52 which, together with the three cases presented herein add up to 55 cases. Forty-six patients were women aged between 19 and 71 years, with a mean age of 40.1 +/- 12.4 years, and the average duration of the disease was 10 years. The most frequently observed rupture sites were the patellar and Achilles` tendons. While almost all patients described were on various doses of corticosteroids, 16 patients concomitantly had Jaccoud`s arthropathy (29%). In conclusion, the association between Jaccoud`s arthropathy and tendon rupture in systemic lupus erythematosus has been underestimated. As almost one-third of the systemic lupus erythematosus patients with tendon rupture also have Jaccoud`s arthropathy, this arthropathy may be recognized as risk marker for tendon rupture.

Chronic polyarthritis as the first manifestation of juvenile systemic lupus erythematosus patients

Objective: To evaluate the prevalence of chronic polyarthritis in juvenile systemic lupus erythematosus (JSLE) and to describe the manifestations, treatments, and outcomes in these patients. Methods: From January 1983 to July 2010, 5419 patients were followed up at the Pediatric Rheumatology Unit of the University Hospital and 271 (5%) of them had JSLE (American College of Rheumatology [ACR] criteria). `Rhupus` was classified as the overlap of juvenile idiopathic arthritis (International League of Associations for Rheumatology [ILAR] criteria) and JSLE. We evaluated demographic data, polyarthritis and other clinical manifestations, disease activity and damage, laboratory exams, radiographic findings, treatments, and outcomes. Results: The prevalence of chronic polyarthritis in this JSLE population was 2.6% (7/271). This articular involvement was the initial manifestation in all seven JSLE patients. The median duration of chronic polyarthritis was 11 months (range 2-15 months). Interestingly, rhupus with chronic polyarthritis and limitation of movement, presence of rheumatoid factor, autoantibodies, and/or radiographic abnormalities (juxtaarticular osteopenia, joint-space narrowing, or erosions) was evidenced in three patients. No patient had deformities of hands and feet associated with Jaccoud`s arthropathy or osteonecrosis. All patients were treated with nonsteroidal anti-inflammatory drugs (NSAIDs, naproxen 10-15 mg/kg/day) when polyarthritis diagnosis was established. Prednisone and antimalarials were administered at JSLE diagnosis. The three non-responsive rhupus patients were treated in conjunction with immunosuppressive drugs (methotrexate, azathioprine, and/or cyclosporine). Conclusions: Chronic polyarthritis was a rare lupus manifestation in active pediatric patients. The interesting overlap between chronic arthritis and lupus, called rhupus suggests a new entity with a different clinical profile and a poor response to treatment with NSAIDs alone. In addition, the occurrence of this association in JSLE patients could be classified as a clinical sub-group of JSLE with possible specific genetic determinants. Lupus (2011) 20, 960-964.

Charcot`s arthropathy secondary to herpetic encephalitis sequelae: an unusual presentation

Neuropathic arthropathy (Charcot`s arthropathy) is a progressive articular disease associated with a reduced sensorial and protector proprioceptive reflex. Its etiology includes many different conditions such as syringomyelia, traumatic lesion causing medullary deformity, spina bifida, diabetic neuropathy, leprosy neuropathy, neurofibromatosis, amyloid neuropathy, alcohol, and repetitive injection of hydrocortisone into joints, among others. However, the relationship between Charcot`s arthropathy and herpetic encephalitis has not yet been described. Herpes encephalitis causes acute and chronic diseases of the peripheral or central nervous system. It can manifest as subacute encephalitis, recurrent meningitis, or myelitis. It can also resemble psychiatric syndromes, diplopia, sensory changes in the face and limbs, personality changes, frontal dysexecutive syndrome, stiff neck, subclinical alterations of the vestibular function, intracranial hypertension, convulsion, hemiparesis, and generally includes motor components, among others. On the other hand, pure peripheral sensory disturbance has not been described. In this article, we report the clinical case of a patient with Charcot`s arthropathy secondary to pure peripheral sensory polyneuropathy as a consequence of progressive herpetic encephalitis sequelae. In this article, the authors report the first case of Charcot`s arthropathy secondary to herpetic encephalitis.

Association between human parvovirus B19 and arthropathy in Belém, Pará, north Brazil

A total of 220 patients with arthropathy were selected in Belém, Pará between January 1994 and December 2000, and screened for the presence of human parvovirus B19 IgM and IgG antibodies by enzyme-linked immunosorbent assay (ELISA). A subgroup (n = 132) of patients with high levels of antibodies (either IgM+/IgG+ or IgM-/IgG+) were examined for the presence of DNA by polymerase chain reaction/nested PCR. Recent/active infection (detection of IgM and/or IgG-specific antibodies and presence of viral DNA) was identified in 47.7% of the 132 individuals with arthropathy. In our study, women were significantly more affected (59.7%) than men (35.4%) (P = 0.0006). The age group of 11-20 years (84.6%), among female patients, and 21-30 years (42.1%), among male, were those with the highest incidence rates. The analysis of the temporal distribution of B19-associated arthropaties showed a cyclic pattern, with peak incidence rates occuring at 3-5 year intervals. Significant diference (P = 0.01) was observed when comparing both the highest (39.0%) and the lowest (11.0%) seropositivity rates for the years of 1995 and 2000, respectively. The interfalangial joints of hands and feet were mostly affected, with 50.0% and 48.0% of cases among both women and men, respectively. In a smaller proportion, other joints such as those of knee, ankle, pulse and shoulder were affected. As for the duration, symptoms lasted 1 to 5 days in 54.0% of the individuals, whereas in 46.0% of them the disease lasted 6-10 days, if considered the subgroup (n = 63) of patients with recent/active infection by parvovirus B19. In our study, joint clinical manifestations occurred symmetrically. Our results indicate that B19 may be an important agent of arthropathies in our region, and this underscores the need for specific laboratory diagnosis when treating patients suffering from acute arthropathy, mainly pregnant women.

Clinical picture of the amyloid arthropathy in patients with chronic renal failure maintained on haemodialysis using cellulose membranes.

The clinical picture of 15 patients (10 male, five female) with amyloid arthropathy secondary to chronic renal failure treated with haemodialysis has been studied. The average period of haemodialysis was 10.8 years. Joint symptoms appeared between three and 13 years after starting haemodialysis. No patient had renal amyloidosis. Early symptoms were varied and often overlapped: knee swelling (seven patients), painful and stiff shoulders (seven), and carpal tunnel syndrome (six) were the most prominent. Follow up showed extension to other joints. Joint effusions were generally of the non-inflammatory type. Radiologically, geodes and erosions of variable sizes were seen in the affected joints, which can develop into a destructive arthropathy. Amyloid was found in abdominal fat in three of the 12 patients on whom a needle aspiration was performed. Four of 12 patients showed changes compatible with amyloid infiltration in the echocardiogram. One patient had amyloid in the gastric muscular layer, another in the colon mucus, and two of four in rectal biopsy specimens. Amyloid deposits showed the presence of beta 2 microglobulin in 10 patients. The clinical and radiological picture was similar to the amyloid arthropathy associated with multiple myeloma. These patients can develop systemic amyloidosis.

Amyloid arthropathy in patients undergoing periodical haemodialysis for chronic renal failure: a new complication.

Seven patients (five male and two female) with chronic renal failure (CRF) treated by periodical haemodialysis presented with swelling and effusion of more than three months' duration in knees (four bilateral), shoulders (two, one of them bilateral), elbow (one), and ankle (one). Four had a carpal tunnel syndrome both clinically and electromyographically (three bilateral). All patients had hyperparathyroidism secondary to their CRF, which was not due to amyloidosis in any of them. The dialysis duration period varied from five to 14 years, with an average of 8.6 years. Amyloid deposits (Congo red positive areas with green birefringence under polarising microscopy) were shown in six of the seven synovial biopsy specimens of the knee, in five of the sediments of the synovial fluids, and in specimens removed during carpal tunnel syndrome surgery. No amyloid was found in the biopsy specimen of abdominal fat of six of the patients. The finding of amyloid only in the synovial membrane and fluid, and carpal tunnel, its absence in abdominal fat, and the lack of other manifestations of generalised amyloidosis (cardiomyopathy, malabsorption syndrome, macroglossia, etc.) and of Bence Jones myeloma (protein immunoelectrophoresis normal) raises the possibility that this is a form of amyloidosis which is peculiar to CRF treated by periodical haemodialysis.

Design of a myofascial therapy protocol for the treatment of hemophilic arthropathy of the knee and ankle

Hemophilic arthropathy limits daily life activities of patients with hemophilia, presenting with clinical manifestations such as chronic pain, limited mobility, or muscular atrophy. Although physical therapy is considered essential for these patients, few clinical studies have demonstrated the efficacy and safety of the various physiotherapy techniques. Physical therapy may be useful for treating hemophilic arthropathy by applying safe and effective techniques. However, it is necessary to create protocols for possible treatments to avoid the risk of bleeding in these patients. This article describes the musculoskeletal pathology of hemophilic arthropathy and characteristics of fascial therapy. This systematic protocol for treatment by fascial therapy of knee and ankle arthropathy in patients with hemophilia provides an analysis of the techniques that, depending on their purpose and methodology, can be used in these patients. Similarly, the protocol's applicability is analyzed and the steps to be followed in future research studies are described. Fascial therapy is a promising physiotherapy technique for treating fascial tissue and joint contractures in patients with hemophilic arthropathy. More research is needed to assess the efficacy and safety of this intervention in patients with hemophilia, particularly with randomized multicenter clinical trials
