Septic arthritis is an inflammation of a joint caused directly by various microorganisms. It is often characterized by many unspecific symptoms. Bacteria is the most often etiological factor.We present a case report of a 76-years old woman with a unilateral septic arthritis of the sacroiliac joint. Bacterial sacroiliitis should be taken into account in patients with sacroiliitis and fever onset.Proper diagnosis can be very often difficult and delayed but fast implementation of antibiotic therapy is extremely important in the treatment process. Diagnostic imaging is crucial to the diagnosis and monitoring of septic arthritis. Magnetic resonance imaging is the most relevant tool for the detection of sacroiliitis, allowing the institution of therapeutic strategies to impede the progression of the disease.
ObjectivesCurrent studies concentrate on the cytokine network and its role in the pathogenesis of spondyloarthritis (SpA). In this study, we analyzed whether the serum cytokine profile (interleukins: IL-10, IL-11, IL-12, IL-15, IL-17, IL-23 and IL-33) correlates with demographic data, clinical manifestations, disease activity and treatment outcome in a group of patients with axial spondyloarthritis.Material and methodsForty-nine patients with an established diagnosis of axial spondyloarthritis (aSpA) and 19 healthy volunteers as controls were enrolled in the study. Clinical evaluation included patient's medical history, 44 joint count, back pain intensity and global disease activity in the preceding week (VAS), the duration of morning stiffness and blood tests. Disease activity was assessed using BASDAI and ASDAS-CRP. Serum concentration of IL-10, IL-11, IL-12, IL-15, IL-17, IL-23 and IL-33 was determined.ResultsIn patients with aSpA, elevated serum concentration of IL-10, IL-15, IL-17 and IL-23 was detected. In the aSpA group we detected higher values of serum concentration of IL-23 and IL-33 in the subgroup with anterior uveitis (83.1 ±184.0 pg/ml vs. 14.0 ±17.1 pg/ml, p < 0.0001 and 45.5 ±71.9 pg/ml vs. 18.4 ±14.3 pg/ml, p < 0.0001, respectively). Additionally, in the subgroup with peripheral arthritis, elevation of serum concentration of IL-12 (249.3 ±246.9 pg/ml vs. 99.9 ±105.9 pg/ml, p = 0.0001) was detected. Patients with preradiological SpA had higher serum concentration of IL-17 than patients with established diagnosis of AS (6.37 ±8.50 pg/ml vs. 2.04 ±2.98 pg/ml, p = 0.0295). No differences in serum concentration of analyzed cytokines were found between the subgroup with low to moderate disease activity and the subgroup with high to very high disease activity.ConclusionsWe report that in aSpA patients, compared to controls, elevated serum concentrations of IL-10, IL-15, IL-17 and IL-23 were observed. Some cytokines may predispose to a more severe course of aSpA.
Lymphomas are one of the serious complications of the primary Sjörgen's Syndrome (pSS). The aim of the study was to evaluate the frequency of lymphoma in pSS. The singe-center retrospective study included 198 Caucasian patients, who met diagnostic criteria for pSS. The type of lymphoproliferative disorder was classified according to the WHO 2016 classification. The mean time of observation, after pSS diagnosis, was 48 weeks. Focus score (FS) ≥ 1 was present in 85% of the patients, and anti-SSA antibodies were detected in 84%. Rheumatoid factor was detected in 130 (65%) patients. Mean disease activity index, according to EULAR Sjörgen's Syndrome disease activity index (ESSDAI), was 8.3 points at the moment of pSS diagnosis. Complement C3 was decreased in 14% of the patients, while 10% showed reduced complement C4. Four patients (2%) were diagnosed with a lymphoma. Most of the patients were diagnosed with mucosa-associated lymphoid tissue lymphoma (MALT), in whom the tumour was located in the parotid gland, and in one patient the stomach was involved. Finally, one patient was diagnosed with a rare B-cell small lymphocytic lymphoma located in the lungs. In this article, we present detailed characteristics of each case. In analysed population the frequency of lymphoma in the course of pSS in patients with pSS is 2%. The variety of lymphoma types in pSS patients imposes individual monitoring in each patient at every checkup visit for disease activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
