DIFFUSE LUNG DISEASE

INTRODUCTION: DAH in the setting of cryoglobulinemia after HCV therapy completion is unreported in the absence of glomerular disease. CASE PRESENTATION: A 62-year-old lady with a past medical history of hypertension, coronary artery disease and hypothyroidism presented with new onset purpuric rash on bilateral lower extremities. . Review of systems was negative except for pruritus around the rash. The patient denied any new medication, sick contacts or tick exposure. On examination the patient was afebrile with normal vitals. Skin revealed palpable purpuric lesions with no significant necrosis. Laboratory workup is summarized in table 1. Skin biopsy came back positive for leukocytoclastic vasculitis. A diagnosis of type 2 mixed cryoglobulinemia (type 2 MC) was established. Patient was started on treatment for hepatitis C with Ledipasvir/Sofosbuvir combination and 12 weeks later patient achieved sustained viral response (SVR). 6 months later, she presented to the emergency department with acute hypoxemic respiratory failure. CT scan identified patch bilateral ground glass opacities. The patient was admitted to the intensive care on Bipap. She underwent an urgent bronchoscopy. Bronchoscopic alveolar lavage was positive for hemosiderin laden alveolar macrophages. A diagnosis of diffuse alveolar hemorrhage (DAH) was established. HCV RNA was documented negative during this admission. Cultures including special stains for pneumocystis were unrevealing. The patient was started on a combination of pulsed methylprednisolone and plasmapheresis and recovered after 5 sessions. DISCUSSION: DAH is a very rare phenomenon in the presence of Cryoglobulinemia with unclear prevalence. Hospital based studies have identified an incidence of 2-3 % (1,2). Disease activity usually corresponds to HCV RNA levels and virologic remission has been shown to cause cryoglobulinemia quiescence. DAH despite RNA clearance begs the question if HCV antibodies have the ability to propagate disease activity independent of SVR. Absence of glomerular disease, lack of Hypocomplementemia and negative rheumatoid factor are other unique features to our case in the setting of pulmonary involvement is also unique to our case. (1,2,3). Our patient also had a favorable outcome with plasmapheresis and steroids alone. Treatment of DAH in the setting of MC is unclear due to the uncommon nature of the diagnosis. Steroids, Rituximab and plasmapheresis have been tried in varying combinations. Our patient declined therapy with Rituximab when presented with the possibility of relapse with HCV. CONCLUSIONS: Higher awareness of pulmonary manifestations of cryoglobulinemia is critical. Reference #1: Amital H, Rubinow A, Naparstek Y.
