Final answer:
The patient's symptoms and test results suggest a form of vasculitis which could be linked to Hepatitis B. Vasculitis is treated with drugs like corticosteroids and immunosuppressants. Pyelonephritis is another possible diagnosis, treated with antibiotics.
Step-by-step explanation:
A patient presenting with blood in the urine (hematuria) and a positive p-ANCA test result, but no lung involvement, could be indicative of a vasculitis such as microscopic polyangiitis which is a p-ANCA associated disease. However, given that Hepatitis B is mentioned, it is important to consider that certain types of vasculitis, like polyarteritis nodosa, can be associated with Hepatitis B infection. Treatment for vasculitis can vary depending on the underlying cause and severity of the disease, but it may include corticosteroids and immunosuppressive drugs.
Pyelonephritis, a type of kidney infection, is diagnosed via urine tests including urinalysis, urine culture, leukocyte esterase, nitrite levels, and may require imaging. Management of pyelonephritis typically includes a course of antibiotics such as penicillins, cephalosporins, or fluoroquinolones, with the choice depending on the severity of infection and the patient's overall health status. For patients with risk factors, hospitalization and intravenous antibiotics may be necessary.
