Final answer:
Blood in the urine along with positive c-ANCA and involvement of the kidneys, lungs, and sinuses suggests Wegener's granulomatosis (GPA), which is treated with immunosuppressive therapy. White blood cells in the urine are typically indicative of infection but may point toward an autoimmune condition such as GPA in this context.
Step-by-step explanation:
The presence of blood in the urine, along with a positive c-ANCA test, kidney, lung, and sinus involvement suggests a diagnosis of Wegener’s granulomatosis (now known as Granulomatosis with Polyangiitis, GPA), which is a form of vasculitis. The recommended treatment typically involves immunosuppressive therapy such as corticosteroids and cyclophosphamide to reduce the body’s immune response. In case of severe renal involvement, plasmapheresis may also be considered.
The presence of white blood cells in the urine usually indicates an infection, often pointing towards urinary tract infection (UTI) or pyelonephritis. However, in the context of c-ANCA and organ involvement, it is more suggestive of an underlying autoimmune condition like GPA. When a patient presents with these symptoms and test results, it is crucial to seek immediate medical attention to begin appropriate treatment and prevent further organ damage.
