Retinal Vasculitis as a Rare Presentation of Microscopic Polyangiitis.
Cureus
December 2024
Internal Medicine, Unidade Local de Saúde de Coimbra, Coimbra, PRT.
Microscopic polyangiitis (MPA) is a rare, autoimmune, small-vessel vasculitis usually described with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA). It encompasses a broad spectrum of clinical features, including fatigue, weight loss, fever, arthralgia, skin lesions, and involvement of the lungs or kidneys. Ocular manifestations, however, are extremely rare.

Ganzhou Institute of Liver Disease, Department of Hepatology, Ganzhou Fifth People's Hospital, Ganzhou 341000, Jiangxi Province, China.
Background: Liver function of chronic hepatitis B (CHB) patients is essentially normal after treatment with antiviral drugs. In rare cases, persistently abnormally elevated α-fetoprotein (AFP) is seen in CHB patients following long-term antiviral treatment. However, in the absence of imaging evidence of liver cancer, a reasonable explanation for this phenomenon is still lacking.

Pediatr Blood Cancer
January 2025
Pediatrics Department, Jean Verdier Hospital, APHP, Bondy, France.
Background: Systemic inflammatory diseases (SIDs) have been reported in patients with sickle cell disease (SCD), but clinical data in children are scarce.
Objectives: To identify clinical and laboratory features at diagnosis of SID in children with SCD and to describe their evolution.
Methods: Data from children with SCD and SIDs were retrospectively collected in a French multicenter study from 1991 to 2018.
Pulmonary fibrosis as the sole manifestation of anti-Ku antibody positivity in the absence of myositis: A case report.
Respir Med Case Rep

Department of Rheumatology of Lucania - UOSD of Rheumatology, "Madonna delle Grazie" Hospital, Matera, Italy.
Background: Anti-Ku antibodies are autoantibodies directed against the Ku protein complex involved in DNA repair. They are typically associated with overlap syndromes featuring polymyositis and systemic sclerosis. Isolated pulmonary involvement without myositis is exceedingly rare.

Division of Allergy, Immunology and Rheumatology, University of Rochester Medical Center, Rochester, NY, United States.
While durable antibody responses from long-lived plasma cell (LLPC) populations are important for protection against pathogens, LLPC may be harmful if they produce antibodies against self-proteins or self-nuclear antigens as occurs in autoimmune diseases such as systemic lupus erythematosus (SLE). Thus, the elimination of autoreactive LLPC may improve the treatment of antibody-driven autoimmune diseases. However, LLPC remain a challenging therapeutic target.
