David X Liu, Peter J Didier, Gail Plauche, Bapi Pahar
Providencia stuartii (P. stuartii) is an opportunistic pathogen and major concern in urinary catheter-related infections in human medicine. Here we report P. stuartii-induced septicemia in an eighteen-year-old, female India-origin Rhesus macaque with multiple traumatic wounds. The animal had neutrophilic leukocytosis, necrosuppurative meningoencephalitis, hypophysitis and bronchopneumonia with vasculitis, thrombosis, and clusters of extracellular Gram-negative bacilli. P. stuartii was isolated from the lesions of the brain and lung and confirmed by PCR and sequencing...

Chronic pulmonary arterial obstructions are caused mostly by chronic pulmonary artery thromboembolism and rarely by vasculitis or intimal sarcoma of the pulmonary artery. We herein report an unusual case of a 42-year-old woman with a solitary obstruction of the pulmonary artery in the right lower lobe of her lung. Because we could not exclude the possibility of intimal sarcoma, middle and lower lobectomy was performed. The resected specimens revealed large vessel vasculitis (LVV) and an isolated lesion in the right lower lobe pulmonary artery...

Here, we established CD4(+)αβTh1 clones specific for rat vascular smooth muscle antigen (VSMAg) that induced vasculitis lesions in the lungs of MRL/Mp-Fas(+/+) mice following adoptive transfer. Six different T cell clones, MV1b1 (Vβ1), MV1b4 (Vβ4), MV1b8.3 (Vβ8.3), MV1b61 (Vβ6), MV1b62 (Vβ6), and MV1b63 (Vβ6), were isolated from the MV1 T cell line from the regional lymph nodes of immunized MRL/Mp-Fas(+/+) mice; the three (Vβ6) clones had unique CDR3 amino acid sequences. Following stimulation with VSMAg-pulsed antigen presenting cells, MV1b61 and MV1b62 failed to secrete interferon-γ and tumor necrosis factor-α, although the other four clones secreted high levels of both cytokines...

The first case reports of levamisole-related disease in cocaine users were published in 2010, although levamisole adulteration of cocaine was first recognized several years earlier. Currently, more than 70% of street cocaine seizures, in the US and the EU, contain levamisole, which could potentially be converted to aminorex, though the reasons for this practice still remain obscure. Here we report two fatal cases of isolated pulmonary vasculitis in abusers of levamisole-adulterated cocaine, where a complete autopsy, full toxicological analysis by gas chromatography-mass spectrometry (GC-MS) using a previously published method of Karch et al...

BACKGROUND AND OBJECTIVE: Pulmonary capillaritis is generally secondary to a systemic autoimmune process. Little is known regarding other causes of pulmonary capillaritis, particularly isolated pulmonary capillaritis (IPC). IPC is defined as pulmonary capillaritis in the absence of evidence of a systemic disease. We aim to describe the aetiology of biopsy-proven pulmonary capillaritis to add to the existing knowledge on aetiologies of pulmonary capillaritis and provide a more detailed description of IPC cases...

Fusobacterium necrophorum causes Lemierre's syndrome - a dramatic and distinct condition beginning with pharyngitis before proceeding to internal jugular vein septic thrombophlebitis and respiratory tract infection in otherwise healthy individuals. It is rare, but by far the most common pathway to parenchymal lung disease with this organism. Here we describe we a 34 year old healthy lady who was nontoxic without any antecedent illness who presented with lung nodules due to fusobacterium necrophorum as the sole manifestation of disease...

A 21-year-old male African elephant (Loxodonta africana) died suddenly with no previous medical history. Grossly, there were severe multifocal epicardial and endocardial hemorrhages of the atria and ventricles, hydropericardium, multifocal pleural hemorrhages, and severe pulmonary congestion and edema. Histologically, there was fibrinoid vasculitis and thrombosis in the heart and lung and myocardial necrosis. Citrobacter freundii was isolated in abundance in pure culture from liver and heart samples. Low levels of multiples types of elephant endotheliotropic herpesvirus (EEHV-6, EEHV-2B, and EEHV-3A) were detected in spleen samples, but not in heart samples...

In this report, we describe a 61-year-old man that presented with isolated pulmonary vasculitis and a positive anti-cyclic citrullinated peptide (CCP) antibody. Within a few months, the patient developed the symmetric polyarthritis consistent with rheumatoid arthritis (RA). Because the anti-CCP antibody is highly specific for RA and vasculitis is a known association of RA, we suspect the pulmonary vasculitis in this patient was the first manifestation of underlying RA. This case extends on previous reports that have shown that lung disease may predate the development of articular RA and that anti-CCP positivity and lung disease may represent a pre-RA phenotype...

Spot welding is used in the automotive and aircraft industries, where high-speed, repetitive welding is needed to join thin sections of metal. Epoxy adhesives are applied as sealers to the metal seams. Pulmonary function abnormalities and airway irritation have been reported in spot welders, but no animal toxicology studies exist. Therefore, the goal of this study was to investigate vascular, immune and lung toxicity measures after exposure to these metal fumes in an animal model. Male Sprague-Dawley rats were exposed by inhalation to 25 mg/m³ to either mild-steel spot welding aerosols with sparking (high metal, HM) or without sparking (low metal, LM) for 4 h/d for 3, 8 and 13 d...

OBJECTIVE: To investigate the effects of pharmacologic ascorbate (vitamin C) against Influenza A/CA/7/09 (H1N12009). METHODS: BALB/c mice inoculated intranasally with influenza virus were treated with ascorbate (3 mg/g) twice daily by intraperitoneal (i.p.) injection for up to 14 d. Control groups received an equivalent volume of normal saline. Body weights were measured daily. To quantify the level of viral replication in the respiratory tract, the mice were euthanized and lungs removed and prepared as whole lung homogenates...

BACKGROUND: Despite its global recognition as a ruminant pathogen, cases of Chlamydia pecorum infection in Australian livestock are poorly documented. In this report, a C. pecorum specific Multi Locus Sequence Analysis scheme was used to characterise the C. pecorum strains implicated in two cases of sporadic bovine encephalomyelitis confirmed by necropsy, histopathology and immunohistochemistry. This report provides the first molecular evidence for the presence of mixed infections of C...

INTRODUCTION: Pulmonary capillaritis is a small-diameter vessel vasculitis of the lung, which may occur in isolation as in isolated pauci-immune capillaritis, usually associated with the systemic vasculitis but it could be also related to collagen vascular diseases and in lung transplant rejection. Pulmonary capillaritis leads to diffuse alveolar hemorrhage.The clinical presentation includes symptoms like dyspnea, cough, pleuritic chest pain, fever and hemoptysis. CASE OUTLINE: A 48 year-old female patient, smoker, presented with progressive dyspnea...

This study was performed to evaluate pathology of experimental Encephalitozoon cuniculi (Iraqi isolate) infection in normal and immunosuppressed mice. Pathological changes were not seen in negative control mice while secondary bacterial infections were noted in the lungs, kidneys, and heart of mice given dexamethasone. Typical E. cuniculi infection lesions were found in brain, livers, lungs, and kidneys of mice given 10(7)  E. cuniculi spores/mouse orally. These lesions were in the form of nonsuppurative meningoencephalitis with vasculitis in brain, interstitial inflammation with infiltration of both lymphocytes and plasma cells in lung tissue, and nonsuppurative interstitial (focal and diffuse) nephritis, presence of vacuole containing mature and immature spores in enterocytes within the tips of villi, and lymphoiod hyperplasia of the white pulp and vasculitis of the intratrabecular vessels...

The diagnosis and treatment of granulomatous lung diseases is challenging. This article describes two of these entities: (1) eosinophilic vasculitis with polyangiitis which is clinically characterized as a combination of bronchial asthma and eosinophilic granulomatous vasculitis. Antoneutrophil cytoplasmic antibodies are present in approximately 40 % of patients. Treatment with steroids is sufficient in patients with isolated pulmonary manifestation but extrapulmonary manifestations, e.g. heart, central nervous system (CNS), kidneys and gastrointestinal tract warrant combined immunosuppression with prednisolone and cyclophosphamide...
