I have been diagnosed with MPA vasculitis but I assume since mine is pAnca I also have ANCA associated vasculitis. My question is, I broke out with a painful horrible rash that looked like MRSA but I was able to identify it as a vasculitis rash. The doctor treaded me with clindamycin. Into my second week of antibiotics I started having severe headaches, no known fever and vomiting which landed me in the hospital. My CBC s showed low WBC s, low RBC s, low platelets and low neutrophils. Was all this caused by a flare up of my vasculitis?
Hi, MPA vasculitis (Microscopic polyangiitis) is usually associated with pronuclear antineutrophil cytoplasmic antibodies (Bianca)in 75% cases. Neutropenia; leukemia; thrombocytopenia are adverse effects of clindamycin.  Anemia, leukocytosis, and thrombocytes are common features of inflammation in MPA vasculitis. Hope I have answered your query. Let me know if I can assist you further.
