Two cases of polyarthritis associated with hepatitis C infection are reported. In Patient 1, stiffness and polyarthritis occurred during the acute stage of hepatitis. The arthritic symptoms lasted for 4 months. A transient polyarthritis recurred 4 yr later. The persistent presence of anti-hepatitis C viral antibodies was noted. Hepatitis C viral RNA (HCV RNA) was identified in the serum using the polymerase chain reaction proving that the patient was a carrier. In Patient 2, polyarthritis occurred associated with chronic hepatitis C liver disease. Synovial biopsy showed infiltration of mononuclear cells. HCV RNA was demonstrated in both serum and SF. These cases suggest an aetiologic association between arthritis and hepatitis C antigenaemia.

In September 2024, bluetongue virus serotype 3 (BTV-3) was first identified in Portugal, specifically in the Alentejo region (Évora District), using molecular diagnostic methods. The initial case involved a sheep exhibiting severe clinical symptoms, including head oedema, prostration, nasal discharge, and significant respiratory distress. A subsequent case was documented in another sheep from a different farm within the same district, which presented with high fever (41.

Background/objectives: This study aimed to develop a novel nanotechnological slow-release drug delivery platform based on hyaluronic acid Microsponge (MSP) for the subcutaneous administration of methotrexate (MTX) in the treatment of rheumatoid arthritis (RA). RA is a chronic autoimmune disease characterized by joint inflammation and damage, while MTX is a common disease-modifying antirheumatic drug (DMARD), the conventional use of which is limited by adverse effects and the lack of release control.
Methods: MSP were synthesized as freeze-dried powder to increase their stability and allow for a facile reconstitution prior to administration and precise MTX dosing.

Interleukin-1 (IL-1) is a pivotal mediator in the pathological progression of osteoarthritis (OA), playing a central role in disease progression. However, the rapid clearance of IL-1 receptor antagonist (IL-1Ra) from the joints may hinder the efficacy of intra-articular IL-1Ra injections in reducing OA-associated pain or cartilage degradation. Sustaining sufficient levels of IL-1Ra within the joints via adeno-associated virus (AAV)-mediated gene therapy presents a promising therapeutic strategy for OA.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease that affects multiple organ systems, often presenting with polyarticular joint manifestations. Despite its relevance, there is currently limited research on the impact of MPs on lupus arthritis.

Objectives: We aimed to explore the possible effects of Kashin-Beck disease (KBD) on the risk of sarcopenia and its possible interaction in the association between the risk of sarcopenia and element concentration.
Methods: This cross-sectional study was conducted among individuals 18-75 years old in Qamdo, a KBD-endemic area. All individuals received physical and radiological examinations before recruitment.
