Intravenous laser blood irradiation and tocilizumab in a patient with juvenile arthritis.

This study presents effects of intravenous laser blood irradiation (ILBI) in a transient immunodeficiency patient with juvenile idiopathic arthritis (JIA) treated with an interleukin-6 receptor inhibitor (Tocilizumab). Biological agents induce JIA remission, but some patients do not respond favorably to this final therapeutic line of defense. ILBI was performed in a 16-year-old male patient, with JIA and transient immunodeficiency. When ILBI was introduced, the patient was receiving disease-modifying drugs, steroids, tocilizumab, and physical therapy. Because the disease was not well controlled, ILBI was applied in addition to other ongoing therapies. The patient underwent 1 session daily, and 10 successive sessions per month, repeated every 3 months, for 7 months. Patient evaluation was performed before ILBI was started and at 3, 6, 9, and 12 months after ILBI initiation, using the ACR Pediatric response. The outcome was evaluated using Pediatric 50, 70, and 90 responses and compared to initial status, after 3, 6, 9, and 12 months. At the end of study, the titre of IgA and IgG levels returned to normal. Synergistic anti-inflammatory effect of ILBI was evident, if applied additionally in combination with tocilizumab, in a patient with a therapy-resistant severe form of JIA and related subacute transient immunodeficiency.

Atypical presentation of systemic lupus erythematosus: parotitis and secondary Sjogren's syndrome. Case report.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by auto antibodies directed against self-antigens, immune complex formation and immune deregulations and may affect joints, skin, kidneys, heart, lungs, nervous system, and immune system. The onset can be variable and the symptoms can occur for many years. Parotitis as the initial manifestation of systemic lupus erythematosus (SLE) is a rare condition and can be associated with Sjogren's syndrome. In this article we present the case of a young patient who was diagnosed with Sjogren's syndrome retrospectively, after she met the criteria for SLE.

Rheumatoid myositis, myth or reality? A clinical, imaging and histological study.

UNLABELLED: Rheumatoid myositis (RM) is still poorly characterized, albeit the concept of muscle involvement in rheumatoid arthritis (RA) is well-recognized as being driven by a wide range of causes including inflammation, drugs, impaired joint flexibility, sedentarism. OBJECTIVE: To describe clinical, serological, imaging and histological pattern of RM. MATERIALS AND METHODS: This is a retrospective study on eight RM selected from a cohort of one hundred and three RA systematically assessed for skeletal muscle involvement. Data collected included clinical, serum muscle enzymes, muscle imaging and biopsy (Hematoxylin-Eosin, modified Gömöri trichrome staining). RESULTS: Routine muscle histology indicated both non-specific muscle fiber damage (changes in fiber size and internal structure: pleomorphic mitochondria, dilated sarcotubular system, multiple internal or subsarcommal nuclei; abnormal fiber types distribution: trend towards type II; atrophy; degenerative/regenerative modifications) and the presence of inflammatory deposits in all patients (mild to moderate, patchy B- and T-cells infiltrates, mainly perivascular and endomysial, but also in the perimysial region classified as polymyositis-like deposits). High levels of serum muscle enzymes, abnormal EMG (short duration, small amplitude, polyphasic motor unit action potentials) without insertional activity and fibrillations, active inflammation on both Doppler ultrasound and MRI were commonly reported. CONCLUSIONS: Traditional analysis of muscle biopsy specimens (Hematoxylin-Eosin, modified Gömöri trichrome staining) is faraway unsatisfactory, only documenting changes in muscle fibers size, architecture, internal structure, and, possibly, detecting perivascular, perimysial or endomysial inflammatory deposits. Upcoming research should address the value of muscle imaging for the diagnosis and evaluation of treatment response and muscle function in rheumatoid myositis.
