Churg-Strauss syndrome (CSS) is a disorder that is characterized by asthma, hypereosinophilia and systemic vasculitis affecting a number of organs. The manifestations of acute cholecystitis and diffuse alveolar hemorrhage are rarely reported in CSS. A 22-year-old woman with bronchial asthma visited our hospital complaining of right upper quadrant pain with a sudden onset. The abdominal computed tomography (CT) scan revealed gall bladder edema consistent with acute cholecystitis. On the initial evaluation, marked hypereosinophilia was observed in the peripheral blood smear. The nerve conduction velocity measurements and a skin biopsy performed to confirm the organ involvement of disease indicated typical mononeuritis multiplex and necrotizing vasculitis, respectively, which was complicated with CSS. On the 12th hospital day, ground glass opacity and consolidations were newly developed on both lung fields. The bronchoalveolar lavage (BAL) fluid showed increasing bloody return in sequential aliquots that were characteristic of a diffuse alveolar hemorrhage. We report a case of CSS with acute cholecystitis and diffuse alveolar hemorrhage.

Diffuse alveolar hemorrhage is a rare but serious and frequently life-threatening complication of a variety of conditions. The first goal in the management of patients with diffuse alveolar hemorrhage is to achieve or preserve stability of the respiratory status. Subsequently, the differential diagnosis is aimed at the identification of a remediable cause of the alveolar hemorrhage. The most common causes of diffuse alveolar hemorrhage with glomerulonephritis are microscopic polyangiitis and Wegener's granulomatosis, followed by Goodpasture syndrome and systemic lupus erythematosus. Microscopic polyangiitis (MPA) is a distinct systemic small vessle vasculitis affecting small sized vessels with few or no immune deposits and with no granulomatosus inflammation. The disease may involve multiple organs such as kidney, lung, skin, joint, muscle, gastrointestinal tract, eye, and nervous system. MPA is strongly associated with antineutrophil cytoplasmic autoantibody (ANCA) that is a useful serological diagnostic marker for the most common form of necrotizing vasculitis. Our report concerns a case of microscopic polyangiitis with diffuse alveolar hemorrhage in a 54-year-old man. He was admitted to our hospital due to dyspnea upon exertion and recurrent hemoptysis. Laboratory findings showed hematuria, proteinuria and deterioration of renal function. In the chest CT scan, diffuse ground glass appearance was seen in both lower lungs. A lung biopsy revealed small vessel vasculitis with intraalveolar hemorrhage and showed a positive reaction to against perinuclear ANCA. The patient was treated with prednisolone and cyclophosphamide. Chest infiltration decreased and hemoptysis and hypoxia improved. He is still being followed up in our hospital with a low dose of prednisolone.

A diffuse alveolar hemorrhage (DAH) is a distinct form of pulmonary hemorrhage that originates from the pulmonary microcirculation. Disseminated intravascular coagulation (DIC) is one cause of DAH. Although HELLP syndrome associated with DIC can cause DAH, there are no published case reports that the authors are aware of. We report the case of a pregnant woman with HELLP syndrome who developed DAH. Because pregnant women with HELLP syndrome can develop DAH as a form of ARDS, a bronchoalveolar lavage may be used to make a differential diagnosis of this lung manifestation.

Two suckling piglets, 4 days and 10 days of age, showed lethargy and dyspnea after birth and mortality had been increased after incoming gilts from breeding farm. At necropsy, the lungs showed diffuse fail to collapse with rubbery consistency, edematous dilatation of interlobular septa, and lobular consolidation with purple red color. Heart was diffuse pale in color and had several irregular linear-shaped macules or patches. Histopathologically, diffuse interstitial pneumonia with the proliferation of type II pneumocytes was present in the lungs of 2 piglets. Alveolar lumens contained necrotic cellular debris derived from neutrophils and macrophages. Multifocal hemorrhage and necrotizing pneumonia with protozoan tachyzoites were observed in the lungs. Severe multifocal to confluent necrotic myocarditis, necrotic encephalitis, and necrotic adrenalitis with intralesional protozoan tachyzoites were observed in piglets. According to immunohistochemical analysis (IHC), Toxoplasma (T.) gondii tachyzoites antigens were confirmed in lung, heart, brain, and adrenal gland. And porcine reproductive and respiratory syndrome virus (PRRSV) antigens were also detected in the cytoplasm of macrophages in lungs using IHC. Based on the gross, histopathologic and immunohistochemical features, two suckling piglets were diagnosed as co-infection of T. gondii and PRRSV.

Microscopic polyangiitis is a systemic small-vessel vasculitis that is primarily associated with necrotizing glomerulonephritis and pulmonary capillaritis. Lung involvement is characterized by a diffuse alveolar hemorrhage. However, rarely central nervous system involvement has been reported to be occurred with the microscopic polyangiitis. Relapse of microscopic polyangiitis are reported to be more frequent than those of polyarteritis nodosa, often after a reduction or discontinuation of the therapy. We would like to report two patients with microscopic polyangiitis. One presented with clinical manifestations of both lung and central nervous system involvements and the other was a case of recurrence during steroid tapering following the steroid pulse therapy.
