    To review the recent medical literature with regard to the etiopathogenic and clinical aspects of the Wegeners Granulomatosis (WG), We carried out a search in the Medline database (1990-2000) that comprises topics related with etiology, epidemiology, pathology, and clinical aspect of WG. 650 abstracts were studied, finding that 125 of them informed topics related with the topic that we wanted to study. Then we got the articles. Some bibliographical references of these articles were considered fundamental for our objectives and we decided to get it too. The articles were classified according to their objectives and execution strategies, as they were revisions, original articles or cases report. We proceeded to their reading and analysis, for the later elaboration of the revision. We made a selection of information based in the following model: definition, history, epidemiology, etiopathogenesis, pathology, clinical aspects, course and evolution, diagnosis criteria, activity markers and treatment. WG is an infrequent disease The pathogenic and the therapeutic aspects are motives of recent and important advances in the medicine research, specially the state of the knowledge of antineutrophil cytoplasmic antibodies (ANCAs) and therapeutic tools which had decrease the mortality of this disease

    Granulomatosis with polyangiitis (GPA) is a small vessel vasculitis that can affect several organs, most commonly the respiratory tract and kidneys. Pituitary involvement is exceptionally rare. Most case reports of GPA of the pituitary gland have been described in middle-aged women who have concomitant ears, nose and throat involvement. The most frequent manifestation is diabetes insipidus due to a preponderance of posterior pituitary infiltration. The majority of cases sustain permanent dama...

    Wegener's granulomatosis (WG) is a severe and potentially lethal granulomatosis. Even though no specific radiological criteria exist, CT may suggest the correct diagnosis at an early stage. Recent improvement in the prognosis is related to earlier diagnosis, allowing the initiation of efficient and specific treatment before any severe complications occur. We reviewed a series of WG cases in order to establish the CT diagnostic criteria. (orig.)

    The authors reviewed the medical histories and radiological examinations of five pediatric patients with a histologic diagnosis of Wegener's granulomatosis (WG) seen over a six year period in whom a total of 22 thoracic CT scans were performed. Involvement of both the upper and lower respiratory tracts was seen in all patients at presentation. One patient had subglottic stenosis necessitating tracheotomy. Pulmonary hemorrhage occurred in three patients at initial diagnosis. Classic cavitary lung nodules were seen in two patients - one at initial presentation, the other at relapse. The plain radiographic lower respiratory tract manifestations of pediatric WG were protean both at initial presentation and during follow up. Similarly, disease expression was highly variable on thoracic CT examinations but, overall multifocal parenchymal infiltrates with or without small peripheral nodules were the commonest thoracic CT manifestations. As a consequence of cytotoxic and corticosteroid therapy the long-term prognosis of WG has improved considerably in recent years. Knowledge of the varied patterns of the primary disease and potential for iatrogenic complications are necessary for successful radiologic assessment of pediatric patients with WG. (orig.)

    Polyangiitis overlap syndrome is defined as systemic vasculitis that cannot be classified into one of the well-defined vasculitic syndromes. In this report, a female patient who presented with vasculitis-like and asthmatic symptoms was diagnosed as having polyangiitis overlap syndrome of granulomatosis with polyangiitis (GPA; formerly known as Wegener's granulomatosis) and eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome). The patient fulfilled the American College of Rheumatology diagnostic criteria for GPA and EGPA. She was successfully treated with immunosuppressants and steroids and has been in remission for 20 months. It is important to establish a proper diagnosis and introduce an appropriate treatment modality in patients with this rare and serious pathology to prevent irreversible organ damage.

    Objective: To study the CT features and to improve the diagnostic accuracy of pulmonary Wegener's granulomatosis. Methods: 11 patients with histopathologically and clinically proven Wegener's granulomatosis were included in the study. Chest radiography was performed in all 11 patients and 8 patients underwent chest CT. Results: Lung abnormalities were noted in 10/11 patients including patchy lung opacities (n=3), multiple nodules (less than 3 cm in diameter, n=4), masses (more than 3cm in diameter, n=3), and cavitations (n=8). Multiple findings were observed in 4 patients. Conclusion: Imaging manifestations of pulmonary Wegener's granulomatosis were variable. Patchy lung opacities, nodules and cavitation were most common. Thin-walled cavity and ring-shaped cavity were characteristic. Pneumonia, abscess, tuberculosis and carcinoma should be included in the differential diagnosis. (authors)

    The case report shows a surprising presentation of pulmonary granulomatosis with polyangiitis (GPA) through symptoms of diabetes insipidus (DI) with granulomatous infiltration of the pituitary gland. The pituitary hormonal dysfunction as a result of granulomatosis of the pituitary gland is rare. Several studies have demonstrated that the incidence of the pituitary dysfunction reaches approx. 1 % of the patients with GPA. However it is mostly presented in patients with the disease already diagnosed. The patient described by us had no clinical expressions of GPA in the respiratory tract. He presented with polyuria and polydipsia. It was not until a more detailed examination of these symptoms was performed that a focal lung disease was detected and diagnosed as GPA. diabetes insipidus - granulomatosis with polyangiitis - granulomatous infiltration of the pituitary gland - pituitary hormonal dysfunction.

    We report a case of Wegener's granulomatosis clinically mistaken for carcinoma in a 21-year-old girl presenting with an ulcerated mass of the nasopharynx associated with enlarged laterocervical nodes. The lesion was clinically suspected as malignant on the basis of clinical and radiological findings (namely, computed tomography scan and positron emission tomography). However, multiple biopsies were not conclusive for malignancy showing histological change suggestive of Wegener's granulomatosis. A serum determination of cANCA supported the diagnosis of Wegener's granulomatosis. Clinical findings and image studies suggested an erroneous diagnosis of malignancy whereas a definitive diagnosis of Wegener's granulomatosis was achieved only after repeated biopsies thus leading to a correct therapeutic approach. The Wegener granulomatosis must be added to the list of the differential diagnoses of the masses of the nasopharynx associated with or without enlarged laterocervical nodes. PMID:24106630

    Wegener's granulomatosis (WG) is rarely diagnosed during the reproductive years and uncommonly manifests for the first time during pregnancy. We report a case of de novo WG presenting at 30 weeks gestation with classical symptoms of WG (ENT, pulmonary). The diagnosis was confirmed by radiological, laboratory, and histological investigations. With a multidisciplinary approach, she had a successful vaginal delivery of a healthy baby. She was treated successfully by a combination of steroids, azathioprine and intravenous immunoglobulin in the active phase of disease for induction of remission and by azathioprine and steroids for maintenance of remission. The significant improvement in her symptoms allowed us to continue her pregnancy to 37 weeks when delivery was electively induced. Transplacental transmission of PR3-ANCA occurred but the neonate remained well. This case of de novo WG during pregnancy highlights the seriousness of this disease and the challenge in management of such patients.

It is manifested as granulomatous necrotizing inflammation of the upper and lower parts of the respiratory tract, glomerulonephritis and systemic vasculitis involving most frequently the skin and oral mucous membrane. Sera markers of this disease are c-ANCA and p-ANCA. Case report. We presented a female patient aged 52 years with purpuric spots that had appeared on the lower legs ten months before admission to our hospital. The disease ran an aggressive course, and a month before admission hemorrhagic bullae, skin ulcers, hoarseness, dyspnea, generalized arthralgia, fatigue and fever had rapidly developed. Histopathological examination of a skin sample revealed necrotizing vasculitis, so that sera markers concentrations were elevated (c-ANCA, p-ANCA. There was a perforation of the nasal septum found on rhinoscopy. During hospitalization acute abdominal pain occurred, a possible tumor in the small intestine and possible granulomas in the liver were seen by multislice computed tomography (MSCT examination, with normal findings on the lungs and kidneys. The treatment started with methylprednisolone: 500 mg/d i.v. infusion for consecutive 3 days, then 60 mg/d. On exploratory laparotomy small bowel perforation and diffuse peritonitis were found. Unstable in the postoperative period, the patient died on the day 12 of hospitalization. Conclusion. The reported patient was with fulminant Wegener’s granulomatosis, dominantly with skin changes and with gastrointestinal manifestation. This case accents the need for rapid systemic clinical evaluation in a severely ill patient with unclear diagnosis.

FONTE DOS DADOS: Os artigos utilizados nessa revisão consistem em ensaios randomizados ou semi-randomizados, estudos de caso-controle, metanálises e artigos de revisão recentemente publicados. Alguns outros artigos foram selecionados devido à sua importância para o tema. RESULTADOS: A enterocolite necrosante é uma importante causa de morbimortalidade neonatal em prematuros. Entre esses, os nascidos com retardo de crescimento intra-uterino apresentam um risco mais elevado. O processo fisiopatológico inicia-se intra-útero e continua após o nascimento. Entre outros fatores envolvidos na fisiopatologia, estão a ação da arginina na produção do óxido nítrico intestinal e a ação do fator de crescimento epidérmico na regeneração celular. A perfuração intestinal ainda é um problema cirúrgico, e evidências melhores quanto à sua abordagem precisam ser avaliadas. Após a cirurgia, a extensão da alça intestinal remanescente, a preservação da válvula ileocecal, assim como a utilização precoce de leite materno ou solução de aminoácidos, são determinantes na duração da nutrição parenteral e no sucesso da readaptação intestinal. Estratégias preventivas estão centradas nas práticas alimentares e, recentemente, na suplementação de aminoácidos. CONCLUSÃO: Com um melhor entendimento do processo fisiopatológico, do manejo clínico e cirúrgico, assim como das medidas de prevenção, importantes resultados serão alcançados em termos de redução da morbimortalidade conseqüente à enterocolite necrosante.OBJECTIVE: To evaluate recently reported findings on necrotizing enterocolitis, Paying particular attention to pathogenesis, management and preventative strategies.

    2015-01-01

    to investigate the incidence of injuries in different vascular beds and the morphopathological changes in vessels in granulomatosis with polyangiitis. The morphopathological features of vascular injuries were investigated in 11 dead patients aged 16--74 years with granulomatosis with polyangiitis. Proliferative and destructive angiitis with predominant involvement of microcirculatory vessels and with development of necrosis-prone granulomas in their walls and perivascularly was established to underlie the clinical manifestations of granulomatosis with polyangiitis. The most typical localization of the pathologic process is the vessels of the upper respiratory tract, lungs, and kidneys. Cardiopulmonary and renal failures are causes of death in the majority of cases. It should be noted that the vessels of the heart, liver, and gastrointestinal tract are frequently involved in the pathological process. Vascular changes in these organs determine the clinical features of granulomatosis with polyangiitis and lead to a number of fatal complications. Granulomatosis with polyangiitis is a systemic disease with polymorphism of clinical manifestations, which requires in-depth analysis based on current precision patient examination methods, including a histopathological study.

    Although pulmonary involvement occurs in the majority of children and adolescents with Wegener's granulomatosis (WG), relatively little has been published regarding the CT imaging manifestations in this group of patients. To determine the frequency and types of chest CT abnormalities in active pediatric WG (pWG). The study was a retrospective examination of 29 chest CT examinations performed at diagnosis (n=14) and during disease flares (n=15) in 18 children. The most common abnormalities were nodules (seen in 90% of examinations), ground-glass opacification (52%), and air-space opacification (45%). Of examinations with nodules, 73% demonstrated nodules >5 mm in diameter and 69% demonstrated more than five nodules; 17% had cavitary lesions. The only abnormality with a significant difference in prevalence between diagnosis and disease flares was air-space opacification, present in 71% and 20%, respectively (P < 0.01). In accordance with the findings of published adult studies and at variance with those of prior pediatric studies, our findings indicate that chest CT abnormalities in active pWG are frequent, most commonly comprising nodules and ground-glass opacification, which may be difficult to detect on plain radiography. We therefore advocate the routine use of chest CT for all affected patients, both at the time of presentation and during disease flares. (orig.)

    Full Text Available Eosinophilic granulomatosis with polyangiitis (EGPA is a multisystemic disorder, belonging to the small vessel ANCA-associated vasculitis, defined as a eosinophil-rich and necrotizing granulomatous inflammation often involving the respiratory tract, and necrotizing vasculitis predominantly affecting small to medium-sized vessels, associated with asthma and eosinophilia. EGPA pathogenesis is not well known: HLA-DRB1*04 and *07, HLA-DRB4 and IL10.2 haplotype of the IL-10 promoter gene are the most studied genetic determinants. Among the acquired pathogenetic factors, the exposure to different allergens, infections, vaccinations, drugs and silica exposure have been involved.Eosinophils are the most characteristic cells in EGPA and different studies have demonstrated their role as effector and immunoregulatory cells.EGPA is considered a disease with a prevalent activation of the Th2 cellular-mediated inflammatory response but also humoral immunity plays an important role. A link between B and T inflammatory responses may explain different disease features. EGPA typically develops into three sequential phases: the allergic phase, distinguished by the occurrence of asthma, allergic rhinitis and sinusitis, the eosinophilic phase, in which the main pathological finding is the eosinophilic organ infiltrations (e.g. lungs, heart and gastrointestinal system and the vasculitic phase, characterized by purpura, peripheral neuropathy and constitutional symptoms.ANCA (especially pANCA anti-MPO are present in 40-60% of the patients. An elevation of IgG4 is frequently found. Corticosteroids and cyclophosphamide are classically used for remission induction, while azathioprine and methotrexate are the therapeutic options for remission maintenance. B-cell depletion with rituximab has shown promising results for remission induction.

    Full Text Available Wegener’s Granulomatosis is a necrotizing granulomatous vasculitis involving small and medium sized vessels. The syndrome is classically defined as having involvement of kidney, lungs and upper respiratory tract (i.e. sinuses. Wegener’s Granulomatosis may be present in other autoimmune or inflammatory diseases, particulary systemic lupus erythematosis (SLE, but most frequently has been associated with polyarteritis and glumerulonephritis.We present a case of wegener’s Granulomatosis (WG in a middle age lady with Rheumatiod Arthritis (RA; and discuss the implications of these two conditions co-existing in one patient. As for as we are aware, through medline and interent research, this is probably the fourth case with such as association of WG and RA and the fist one in Iran.Presentation of new uncontrollable sing and symptoms, in a previously well controlled RA patient, might suggest a new overlapping syndrome like Wegener’s Granulomatosis besides to flare up of previous disease as differential diagnosis

    Subglottic stenosis (SGS) in granulomatosis with polyangiitis (GPA) may result from active disease or from chronic recurrent inflammation. The objective of the study was to describe the clinical features and treatment of patients with subglottic stenosis. We retrospectively reviewed the medical records of all patients with SGS due to GPA diagnosed at Rheumatology deparment between January 2000 and June 2015. We present 4 cases of SGS at our department during a period of 15 years. The interval between the presentation of the GPA and SGS varied between 2 and 144 months. The leading symptoms of SGS were dyspnoea on exertion and stridor. Three patients presented SGS without evidence of systemic activity. Two patients presented SGS grade i and received tracheal dilatation; two recurred and three needed a tracheostomy due to severe airway-limiting stenosis. SGS presents high morbidity. Even though subglottic dilatation provides symptomatic relief, recurrences may present. Severe airway-limiting stenosis often requires tracheostomy.

    Full Text Available A 70-year-old female presented with a 4-week history of dry cough and wheezing. Chest radiograph showed a 10.5 cm mass-like density in the anterior mediastinum which had not been previously visualized. Computed tomography scan (CT of the chest showed a right hilar mass encasing and narrowing right upper lobe bronchus and right mainstem bronchus and secondary atelectatic changes. Biopsy was consistent with a diagnosis of lymphomatoid granulomatosis Grade 3. She responded well clinically and radiologically to therapy. Lymphomatoid granulomatosis is a rare EBV-associated disorder which is considered a lymphoproliferative disease. The most common radiographic feature is multiple lung nodules. An isolated hilar mass is an exceptionally rare presentation of this rare disease.

    Our objective was to describe the CT findings of thoracic Wegener's granulomatosis. At presentation, both conventional and thin-section CT scans were available in 30 patients with Wegener's granulomatosis. Serial CT scans (range of intervals: 1-25 months, mean 4.5 months) were available in 20 patients. The initial and follow-up CT scans were analyzed retrospectively by two observers in terms of pattern and extent of parenchymal and airway lesions. Positive CT findings were seen in 29 of 30 (97%) patients at initial presentation. The most common pattern was nodules or masses seen in 27 of 30 (90%) patients. They were multiple in 23 of 27 (85%) patients, bilateral in 18 (67%), subpleural in 24 (89%), and peribronchovascular in 11 (41%) in distribution. Bronchial wall thickening in the segmental or subsegmental bronchi was seen in 22 (73%) patients. Large airways were also abnormal in 9 (30%) patients. Patchy areas of consolidation and ground-glass opacity were seen in 7 (23%) patients, respectively. In 17 of 20 (85%) patients in whom follow-up CT scans were available, the parenchymal or airway lesion showed complete or partial improvement with treatment. The CT findings of Wegener's granulomatosis, although multiple and variable, consist mainly of bilateral subpleural or peribronchovascular nodules or masses and bronchial wall thickening in the segmental or subsegmental bronchi. Parenchymal and airway lesions improve with treatment in most patients. (orig.)

    Seven dogs with pulmonary lymphomatoid granulomatosis were reviewed. The disease occurred in six large-breed and one small-breed dogs. The dogs were five to 14 years old (mean, 8.4; median, 7), and four of seven dogs were males. Three dogs had been previously treated with adulticide therapy for canine dirofilariasis. Clinical histories included a progressive respiratory disease characterized by varying degrees of cough, dyspnea, exercise intolerance, and weight loss. Thoracic radiographic features included hilar lymphadenopathy, pulmonary masses of varying sizes, and mixed pulmonary patterns of lobar consolidation with ill-defined interstitial and alveolar pulmonary infiltrates. Cardiovascular changes compatible with chronic dirofilariasis were present in three dogs. The clinical course was usually progressive and fatal. The survival time ranged from six days to four years (mean, 12.5 mos; median, 3 mos). Gross and histologic features included mass lesions with areas of necrosis that replaced normal pulmonary architecture. Cytologically, these lesions were characterized by infiltration with pleomorphic, angioinvasive mononuclear cells that often resulted in vascular obliteration. The infiltrating cells resembled large lymphoid cells that possessed large hyperchromatic nuclei and small amounts of cytoplasm. Systemic lymphoid neoplasia with peripheral lymphadenopathy was diagnosed in two dogs. In both cases, lymph-node cytology was similar to the cellular infiltrates found in the lungs and consistent with a diagnosis of lymphomatoid granulomatosis. These features are compared with previously reported cases of canine lymphomatoid granulomatosis and those features identified in a similar disease described in man

    Full Text Available We report a case of Wegener’s granulomatosis clinically mistaken for carcinoma in a 21-year-old girl presenting with an ulcerated mass of the nasopharynx associated with enlarged laterocervical nodes. The lesion was clinically suspected as malignant on the basis of clinical and radiological findings (namely, computed tomography scan and positron emission tomography. However, multiple biopsies were not conclusive for malignancy showing histological change suggestive of Wegener’s granulomatosis. A serum determination of cANCA supported the diagnosis of Wegener’s granulomatosis. Clinical findings and image studies suggested an erroneous diagnosis of malignancy whereas a definitive diagnosis of Wegener’s granulomatosis was achieved only after repeated biopsies thus leading to a correct therapeutic approach. The Wegener granulomatosis must be added to the list of the differential diagnoses of the masses of the nasopharynx associated with or without enlarged laterocervical nodes.

    Full Text Available Necrotizing enterocolitis is the most frequently occurring gastrointestinal disorder in premature neonates. Animal models of necrotizing enterocolitis and prenatal administration of cortisone have demonstrated that cortisone may accelerate maturation of the mucosal barrier, therefore reducing the incidence of this gastrointestinal disorder. The authors present a review of the literature of the most important risk factors associated with necrotizing enterocolitis, such as inflammatory gastrointestinal mediators, enteral feeding and bacterial colonization, and immaturity of the gastrointestinal barrier, and we emphasize the necessity for additional studies to explore the prenatal administration of cortisone as a preventive strategy for necrotizing enterocolitis.A enterocolite necrosante é a mais freqüente patologia gastrointestinal adquirida no período neonatal, acometendo preferencialmente o recém-nascido prematuro. Estudos experimentais sugerem que a corticoterapia pré-natal acelera a maturação da mucosa gastrintestinal, levando a diminuição da incidência desta doença. Os autores apresentam uma revisão da literatura em relação aos principais fatores fisiopatológicos associados a enterocolite necrosante, tais como mediadores inflamatórios gastrintestinais, nutrição enteral e colonização bacteriana e imaturidade gastrintestinal e enfatizam a necessidade de mais estudos que avaliem a influencia da corticoterapia pré-natal com fator de prevenção da enterocolite necrosante.

    Splenic involvements in Wegeners granulomatosis (WG) are rarely diagnosed ante-mortem, while an autopsy is able to reveal a high rate of spleen lesions (78 - 100%). To date, there have been a few reported cases of splenic abnormalities in WG, including: splenomegaly, capsular adhesion, dysfunction and infarction. We reported a case of biopsy-verified WG with radiological evidence of diffuse spleen infarction despite the lack of any clinical symptoms. We concluded that due to a potential risk of severe hemorrhagic complications when anticoagulant therapy is necessary, radiological assessment of spleen should be performed regularly in this group of patients, particularly because spleen involvement can be asymptomatic.

A number of patients with this condition have undergone lung transplantation for respiratory failure. However, a history of drug abuse is often considered to be a contraindication to transplantation in the context of limited donor resources. A patient with pulmonary talc granulomatosis secondary to intravenous methylphenidate injection who underwent successful lung transplantation and subsequently presented with recurrence of the underlying disease in the transplanted lung 18 months after transplantation is reported.

    Full Text Available Eosinophilic granulomatosis with polyangiitis (EGPA, formerly named Churg-Strauss syndrome, is a rare systemic small- and medium-sized-vessel vasculitis, characterized by the presence of severe asthma as well as blood and tissue eosinophilia. Gastrointestinal (GI symptoms, like diarrhea and abdominal pain, are common; however, there are few reports of histologic evidence of GI involvement. We report the case of a patient on treatment for EGPA who presented with recurrent small bowel obstruction and choledocholithiasis. Biopsies of the esophagus, small bowel and common bile duct showed diffuse eosinophilia, with clear EGPA in the GI tract. Improved awareness of GI EGPA may allow for timely management of this disorder.

    Differential diagnosis and detection of malignant lesions in mammography poses a challenge for many diagnosticians. Although mammography continues to be the best and cost-effective way to detect breast cancer, it has its limitations due in part to the radiological appearance of changes of a very rare condition. We are presented with changes that have met well-known radiologic criteria for the diagnosis of malignancy, yet they turn out to be benign, because they belong to a group of extraordinary lesions. In June 2010, a 56-year-old woman found a lump in her right breast. Mammography performed at another medical center, revealed a change 12 mm in diameter, rated as BI-RADS 4C. Physical examination revealed a palpable lesion, 15 mm in diameter. Ultrasonography revealed hypoechogenic change with ill-defined outlines, size 14×10 mm – BI-RADS 5. Fine needle aspiration biopsy was done and revealed no atypical cells. The patient underwent an open surgical biopsy and a histopathological diagnosis was suggested to be a type of Wegener’s granulomatosis. Exclusion of cancer enabled the continuation of medical treatment of the underlying disease. There were no changes in the breast in follow-up studies. The differential diagnosis of breast tumors should include rare conditions that can sometimes mimic breast cancer. One of them is Wegener’s granulomatosis. Both, the diagnosis and treatment of the disease, require the cooperation of specialists from various fields, including clinicians, pathologists and radiologists

    Wegener granulomatosis is a multisystem disease of unknown cause characterized by a necrotizing granulomatous vasculitis. In comparison to other vasculitides, the lung is the most common organ involved in wegener granulomatosis presenting with a very aggressive airways pathology and chronic relapsing course. Chest radiographs fail to describe the pattern and distribution of thoracic pathology sufficiently, and CT has shown to be more sensitive for detecting lung involvement. We present the CT findings of 57 patients with wegener granulomatosis and a review of the literature.

Wegener's granulomatosis is a rare disease of unknown etiology, is characterized histologically by a necrotizing granulomatous vasculitis that most commonly involves the lungs together with the nasal pathways, paranasal sinuses, and kidneys, but may affect any organ system. There is increasing recognition of early forms of wegener's granulomatosis with limited disease extension an low activity. Treatment with cyclophosphamide and corticosteroids suppresses disease activity and results in long-term. Remissions. C-antineutrophil cytoplasmic antibodies and acute-phase reactants are helpful in monitoring overall activity, but they do not reflect the manifestation of disease in specific organ systems

    Full Text Available ABSTRACT We report a case of bilateral acute angle-closure glaucoma in a patient with undiagnosed granulomatosis with polyangiitis (Wegener's. A 59-year-old man presented with a severe headache, ocular pain, blurred vision, shortness of breath, and mild fever. Clinical examination revealed conjunctival chemosis, corneal edema, and shallow anterior chambers. Closed angles were observed bilaterally on gonioscopy. The patient was treated with intravenous mannitol, oral acetazolamide, and anti-glaucomatous eye drops. Over the following two days, his vision improved and intraocular pressures decreased. Subsequently, laser iridotomies were performed bilaterally and the patient attended consultations with our departments of respiratory medicine, nephrology, and rheumatology and was subsequently diagnosed with granulomatosis with polyangiitis. Bilateral acute angle-closure glaucoma is a very rare ocular manifestation of granulomatosis with polyangiitis. The association of this clinical entity with Wegener's granulomatosis remains unknown.

    Wegener granulomatosis (WG) is a cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA)-associated, multi-system, necrotizing granulomatous vasculitis. Inflammation of the nasal or oral mucosa, and lung and kidney involvements are typical in the course of the disease. In rare cases, pituitary involvement may occur and cause panhypopituitarism. Pituitary involvement is very rare, and only two pediatric case reports have been published to date out of a total of 24 cases. This is a case report of an adolescent patient who presented with panhypopituitarism symptoms and was later diagnosed with WG. A 16-year-old female patient complained of fever, headache, purulent nasal discharge and severe muscle and joint pain. Additionally, she had polyuria and polydipsia. Investigations revealed a pituitary mass and panhypopituitarism. Positivity of c-ANCA and renal biopsy result compatible with WG confirmed the diagnosis.

    Eosinophilic granulomatosis with polyangiitis (EGPA) (Churg-Strauss), is a rare necrotizing vasculitis of small-sized vessels, associated to antimyeloperoxydase ANCA in 40% of patients. EGPA occurs in patients with asthma. Asthma is sever, associated with eosinophilia and extrapulmonary symptoms. Among them, mononeuritis multiplex is the most frequent symptom. When cardiac involvement is present, prognosis is poor. Despite a good overall prognosis, deaths are caused by vasculitis activity, gastrointestinal and cardiac involvement. Treatment is well codified based on steroids, which are quickly effective. Immunosuppressants combined with corticosteroids are compulsory to treat the most sever forms, mainly when cardiac and gastrointestinal or renal symptoms are present. Copyright © 2012.

    Granulomatosis with polyangiitis (GPA) is a rare but serious small vessel vasculitis with heterogeneous clinical presentation ranging from mainly localised disease with a chronic course, to a florid, acute small vessel vasculitic form characterised by severe pulmonary haemorrhage and/or rapidly progressive vasculitis or other severe systemic vasculitic manifestations. Cardiac involvement is, however, uncommon in the paediatric population. We report a case of a 16-year-old male who presented with peripheral gangrene and vegetation with unusual location on the supporting apparatus of the tricuspid valve, initially considered to have infective endocarditis but ultimately diagnosed with GPA. We provide an overview of the limited literature relating to cardiac involvement in GPA, and the diagnostic challenge relating to infective endocarditis in this context, especially focusing on the interpretation of the antineutrophil cytoplasmic antibody (ANCA) and the characteristic clinical features to identify in order to promptly recognise GPA, since timely diagnosis and treatment are essential for this potentially life-threatening condition.

    A 43 year-old woman consulted due to 2 months of swelling on the superolateral side of the left orbit, with pain and erythema. An excisional biopsy was performed that revealed vasculitis with polyangiitis of the lacrimal gland. A systemic study showed that no other system was compromised. Orbital involvement occurs in up to 60% of patients with granulomatosis with polyangiitis. The involvement of the lacrimal gland is rare and often unilateral. Serological tests are generally negative, both in initial stages, as in localized forms of the disease. Copyright © 2016 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    Eosinophilic granulomatosis with polyangiitis is a complex multisystemic syndrome with heterogeneous presentation. Most often, there is a clinical history of asthma or other atopic conditions, and current presentation generally includes signs of cutaneous or pulmonary involvement. Very few reports described myalgia or weakness as the chief complaint. Of these, only a few included muscle biopsy evaluation and none showed convincing evidence of primary myositis. We believe this report is the first to demonstrate true myositis in the setting of early eosinophilic granulomatosis with polyangiitis. This report describes a 74 year old Caucasian man, with no known allergies, presenting severe myalgia, muscle weakness, jaw claudication, and fever. Blood work showed marked eosinophilia and high creatine kinase levels. Biceps brachialis muscle biopsy revealed eosinophilic necrotizing vasculitis and true myositis with myophagocytosis of non-necrotic fibers and strong sarcolemmal MHC-1 overexpression by immunohistochemistry. This patient was successfully treated with prednisone and azathioprine. Our finding of true myositis in a case of eosinophilic granulomatosis with polyangiitis suggests that primary auto-immunity against muscle fibers, distinct from the secondary effects of vasculitis, can occur in this entity and may represent an overlap syndrome. Early recognition of eosinophilic granulomatosis with polyangiitis in patients presenting with myositis may provide an opportunity to treat the vasculitis before onset of severe multisystemic disease. We recommend the use of muscle biopsy with immunohistochemistry for MHC-1 to confirm the diagnosis of myositis in the setting of eosinophilic granulomatosis with polyangiitis.

    Lymphomatoid granulomatosis (LG) is a rare, aggressive extranodal Epstein-Barr virus (EBV)-positive B-cell lymphoproliferative disease. The purpose of our study was to analyze the CT and fluorodeoxyglucose positron emission tomography (FDG-PET) findings of pulmonary LG. Between 2000 and 2009, four patients with pathologically proven pulmonary LG and chest CT were identified. Two of these patients also had FDG-PET. Imaging features of LG on CT and PET were reviewed. Pulmonary nodules or masses with peribronchovascular, subpleural, and lower lung zonal preponderance were present in all patients. Central low attenuation (4 of 4 patients), ground-glass halo (3 of 4 patients), and peripheral enhancement (4 of 4 patients) were observed in these nodules and masses. An air-bronchogram and cavitation were seen in three of four patients. FDG-PET scans demonstrated avid FDG uptake in the pulmonary nodules and masses. Pulmonary LG presents with nodules and masses with a lymphatic distribution, as would be expected for a lymphoproliferative disease. However, central low attenuation, ground-glass halo and peripheral enhancement of the nodules/masses are likely related to the angioinvasive nature of this disease. Peripheral enhancement and ground-glass halo, in particular, are valuable characteristic not previously reported that can help radiologists suggest the diagnosis of pulmonary LG.

    Granulomatosis with polyangiitis (GPA) is a multi-organ disease which mostly affects lungs, kidney, and head and neck region. We report a rare case of acute laryngeal dyspnea and rapidly progressive pulmonary changes as first manifestations of disease. A 53 year-old woman presented with symptoms of two-week dyspnea, which aggravated rapidly in the preceding hours. Laryngological examination revealed subglottic infiltrations and vocal fold oedema which required urgent tracheotomy. During few days she developed gingival ulcerations and pulmonary infiltration with negative serum c-ANCA titers. The histopathological examination of subglottic and gingival biopsies and the clinical picture established the diagnosis of GPA. She was treated with prednisone and cyclophosphamide with recovery; however, during over 3 years of follow-up, pulmonary symptoms relapsed and subglottic stenosis persisted. The difficulties in diagnosis and treatment in this unusual presentation of GPA are outlined with conclusion that in patients with subglottic infiltration, which develops rapidly, even when this is a sole presentation of the disease, and when c-ANCA are negative, GPA should always be considered.

    Although pulmonary involvement occurs in the majority of children and adolescents with Wegener's granulomatosis (WG), relatively little has been published regarding the CT imaging manifestations in this group of patients. To determine the frequency and types of chest CT abnormalities in active pediatric WG (pWG). The study was a retrospective examination of 29 chest CT examinations performed at diagnosis (n=14) and during disease flares (n=15) in 18 children. The most common abnormalities were nodules (seen in 90% of examinations), ground-glass opacification (52%), and air-space opacification (45%). Of examinations with nodules, 73% demonstrated nodules >5 mm in diameter and 69% demonstrated more than five nodules; 17% had cavitary lesions. The only abnormality with a significant difference in prevalence between diagnosis and disease flares was air-space opacification, present in 71% and 20%, respectively (P < 0.01). In accordance with the findings of published adult studies and at variance with those of prior pediatric studies, our findings indicate that chest CT abnormalities in active pWG are frequent, most commonly comprising nodules and ground-glass opacification, which may be difficult to detect on plain radiography. We therefore advocate the routine use of chest CT for all affected patients, both at the time of presentation and during disease flares. (orig.)

  9. Strawberry gingivitis as the first presenting sign of wegener's granulomatosis: report of a case

    Science.gov (United States)

    2011-01-01

    Wegener's granulomatosis is a rare multi-system disease characterized by the classic triad of necrotizing granulomas affecting the upper and lower respiratory tracts, disseminated vasculitis and glomerulonephritis. Oral lesions as a presenting feature are only encountered in 2% of these cases. Hyperplastic gingival lesions or strawberry gingivitis, is a characteristic sign of Wegener's granulomatosis. The latter consists of reddish-purple exophytic gingival swellings with petechial haemorrhages thus resembling strawberries. Recognition of this feature is of utmost importance for timely diagnosis and definitive management of this potentially fatal disease. A case of strawberry gingivitis as the first presenting sign of Wegener's granulomatosis affecting a 50-year-old Malay male is reported here. The differential diagnosis of red lesions that may present in the gingiva is discussed. PMID:21813375

    Wegener's granulomatosis is a necrotizing granulomatous vasculitis of autoimmune origin that primarily affects the upper and lower airways and kidneys. It is very rare in children and adolescents. When started at a young age it is often associated with subglottic stenosis. Subglottic stenosis is a potentially fatal manifestation of Wegener's granulomatosis. Its diagnosis requires a high index of suspicion since it might develop in the absence of other signs of activity. Occasionally, subglottic stenosis may present as the initial manifestation of the disease. Diagnosis is confirmed by endoscopic visualization of the lesion. The treatment is complex, and it often requires repeated interventions due to restenosis. We present a 13-year-old patient with subglottic stenosis secondary to Wegener's granulomatosis. We describe the clinical manifestations, diagnosis and treatment of this rare cause of respiratory distress in the pediatric population. Sociedad Argentina de Pediatría.

The prevalence of Wegener’s granulomatosis is three cases per 100,000 patients. Cardiovascular, neurologic, cutaneous, and joint manifestations have been reported in many case reports and case series. Gastrointestinal manifestations are less noted in Wegener’s granulomatosis, although they have been previously reported in the form of intestinal perforation and intestinal ischemia. Additionally, there are characteristic findings of vasculitis that are noted with active Wegener’s granulomatosis of the small bowel. We report a case of an elderly patient who presented with weight loss, diarrhea, and hematochezia. His symptoms were chronic and had lasted for more than 1 year before diagnosis. Inflammatory bowel disease or chronic enteritis due to Salmonella arizonae because of reptile exposure originally were suspected as etiologies of his presentation. The findings of proteinuria, renal failure, and pauci-immune glomerulonephritis on renal biopsy, in conjunction with an elevated c-ANCA titer, confirmed the diagnosis of Wegener’s granulomatosis with associated intestinal vasculitis. This case demonstrates an atypical presentation of chronic duodenitis and jejunitis secondary to Wegener’s granulomatosis, which mimicked inflammatory bowel disease.Keywords: ANCA-associated vasculitis, Wegener’s syndrome, pauci-immune glomerulonephritis, Salmonella arizonae, inflammatory bowel disease

    Full Text Available In 2015, guidelines for the diagnosis and treatment of eosinophilic granulomatosis with polyangiitis, formerly known as Churg-Strauss syndrome, were prepared with the participation of experts from 5 countries of Europe, the USA, and Canada, who accumulated scientific achievements and currently gained clinical experience. The proposed guidelines should not be regarded as final standards, but must become a guide for the selection of a personification strategy for managing patients with eosinophilic granulomatosis with polyangiitis and serve as a starting point for further investigations. The purposes of the publication are general characterization of the key points of the guidelines and discussion of some debate problems.

    To evaluate the clinical features of audiologic impairment and its relationship with the nasal, vestibular, and rheumatologic profile in a cohort of patients with eosinophilic granulomatosis with polyangiitis (EGPA), formerly named Churg-Strauss syndrome. Prospective cross-sectional study. Thirty-nine patients with EGPA, considered controlled according to the Birmingham Vasculitis Activity Score and the Vasculitis Damage Index, underwent a complete audiologic evalutaion with otomicroscopy, impedance audiometry, speech audiometry, and auditory brainstem responses; rhinologic evaluation was made by means of fiberoptic endoscopy and nasal cytology; the clinical evaluation was completed with analysis of the facial function and, in patients with referred vertigo, with videonystagmography (VNG). Data were compared to the rheumatologic profile (eosinophil count, antineutrophil cytoplasmic antibodies status). Thirty-four of 39 patients fulfilled the inclusion criteria. Of those, 18 (52, 8%) were affected by variable degrees of hearing loss (sensorineural hearing loss [SNHL]) in four cases (11, 8%), mixed sensorineural and conductive hearing loss in two (5, 9%), presbycusis in six (17, 6%), and otitis media with effusion (OME) in six (17, 6%). Vestibular impairment was represented by benign paroxysmal positional vertigo and unspecific dizziness in three (8, 8%) and four cases (11, 8%), respectively, all with normal VNG. Ear involvement was statistically related to the EGPA vasculitic pattern and independent from the nasal impairment, cytology, and duration of nasal symptoms. No facial palsy was registered. In our experience, the largest in the existing literature, the otological involvement in EGPA is common and may occur variably as SNHL or OME. Otological involvement occurs early in the course of the disease process, but is nonspecific in making the diagnosis of EGPA. Its recognition is therefore fundamental. 4.

    To investigate the epidemiology of granulomatosis with polyangiitis (GPA) over a 15-year period in a defined area of northern Italy. All patients with incident GPA diagnosed from January 1, 1995 to December 31, 2009 living in the Reggio Emilia area were identified by looking at computerized hospital discharge diagnoses, by contacting Reggio Emilia Hospital physicians and community-based specialists, and by checking the databases of the pathology and the laboratory departments and the Reggio Emilia district database for rare diseases. Patients were classified according to the European Medicines Agency (EMA) algorithm. Patients were followed up from the time of diagnosis until either their death or December 31, 2011. For each case, we identified 20 control subjects from the same geographic area matched for age and gender. A total of 18 patients (7 men and 11 women) with GPA were identified. The overall age- and sex-adjusted incidence rate (IR) was 2.4 per million (95% CI: 1.2-3.5). The mean annual IR increased from 1.7/million/year during 1995-1999 to 3.4 during 2005-2009. The highest IR occurred in females aged 70-79 years (13.5 per million; 95% CI: 5.0-30.0) and in males aged ≥ 80 years (14.9 per million; 95% CI: 2.5-49.4). The prevalence of GPA on December 31, 2009 was 34.3 per million (95% CI: 20.3-54.2). The point prevalence per million increased from 17.8 (95% CI: 7.7-35.1) in 1999 to 34.3 (95% CI: 20.3-54.2) in 2009. Survival among individuals with GPA was significantly reduced compared to that observed in the matched control population (p < 0.001). In the Italian population, GPA is very uncommon and GPA patients have reduced survival. Copyright © 2014 Elsevier Inc. All rights reserved.

    Orofacial granulomatosis is a rare chronic granulomatous inflammatory disease of the lips, face and mouth. The aetiology remains unclear but may involve an allergic component. Improvements have been reported with cinnamon- and benzoate-free diets. To explore the prevalence of compound and food sensitivity and examine the dietary treatments used in orofacial granulomatosis. A comprehensive literature search was carried out and relevant studies from January 1933 to January 2010 were identified using the electronic database search engines; AGRIS 1991-2008, AMED 1985-2008, British Nursing and Index archive 1985-2008, EMBASE 1980-2008, evidence based medicine review databases (e.g. Cochrane DSR), International Pharmaceutical and Medline 1950-2008. Common sensitivities identified, predominantly through patch testing, were to benzoic acid (36%) food additives (33%), perfumes and flavourings (28%), cinnamaldehyde (27%), cinnamon (17%), benzoates (17%) and chocolate (11%). The cinnamon- and benzoate-free diet has been shown to provide benefit in 54-78% of patients with 23% requiring no adjunctive therapies. A negative or positive patch test result to cinnamaldehyde, and benzoates did not predict dietary outcome. The most concentrated source of benzoate exposure is from food preservatives. Use of liquid enteral formulas can offer a further dietary therapy, particularly in children with orofacial granulomatosis. Management of orofacial granulomatosis is challenging but cinnamon- and benzoate-free diets appear to have a definite role to play. © 2011 Blackwell Publishing Ltd.

    Full Text Available OBJECTIVES: To determine the possible association of serum 25-hydroxyvitamin D (25OHD levels with disease activity and respiratory infection in granulomatosis with polyangiitis patients during two different periods: winter/spring and summer/autumn. METHODS: Thirty-two granulomatosis with polyangiitis patients were evaluated in the winter/spring, and the same patients (except 5 were evaluated in summer/autumn (n=27. The 25OHD levels were measured by radioimmunoassay. Disease activity was assessed by the Birmingham Vasculitis Activity Score Modified for Wegener’s Granulomatosis (BVAS/WG and antineutrophil cytoplasmic antibody (ANCA positivity. Respiratory infection was defined according the Centers for Disease Control and Prevention criteria. RESULTS: 25OHD levels were lower among patients in winter/spring than in summer/autumn (32.31±13.10 vs. 38.98±10.97 ng/mL, p=0.04. Seven patients met the criteria for respiratory infection: 5 in winter/spring and 2 in summer/autumn. Patients with respiratory infection presented lower 25OHD levels than those without infection (25.15±11.70 vs. 36.73±12.08 ng/mL, p=0.02. A higher frequency of low vitamin D levels (25OHD<20 ng/mL was observed in patients with respiratory infection (37.5% vs. 7.8, p=0.04. Serum 25OHD levels were comparable between patients with (BVAS/WG≥1 plus positive ANCA and without disease activity (BVAS/WG=0 plus negative ANCA (35.40±11.48 vs. 35.34±13.13 ng/mL, p=0.98. CONCLUSIONS: Lower 25OHD levels were associated with respiratory infection but not disease activity in granulomatosis with polyangiitis patients. Our data suggest that hypovitaminosis D could be an important risk factor for respiratory infection in granulomatosis with polyangiitis patients.

    Eosinophilic granulomatosis with polyangiitis is a rare, necrotizing systemic vasculitis associated with asthma and hypereosinophilia. Its cause and pathophysiology are still being elucidated. We report a case of eosinophilic granulomatosis with polyangiitis in a 50-year-old Caucasian woman who presented with chest pain, dyspnea at rest, fever, and periorbital swelling. She was found to have significant hypereosinophilia and cardiac tamponade physiology. A biopsy confirmed extensive infiltration of both lungs and pericardium by eosinophils. She did not have any anti-neutrophil cytoplasmic antibodies. Eosinophilic granulomatosis with polyangiitis diagnosis does not require the presence of anti-neutrophil cytoplasmic antibodies. Anti-neutrophil cytoplasmic antibody-positive and anti-neutrophil cytoplasmic antibody-negative eosinophilic granulomatosis with polyangiitis may present with different clinical phenotypes, perhaps suggesting two distinct disease etiologies and distinct pathophysiology.

    Granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis) is an autoimmune systemic small-vessel vasculitis, associated with the presence of anti-neurophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA). It is characterized by necrotizing granulomas, usually affecting the airways and kidneys. GPA should be considered when patients do not improve despite adequate treatment of otologic symptoms, when patients have unspecific symptoms suggesting systemic disease (e.g. fever, malaise), or when other organs are involved (kidney, lungs, etc.). We present an interesting case of a 14-year-old female with eight-weeks of bilateral otalgia, unilateral facial nerve palsy, decreased appetite, and fatigue refractory to steroid, anti-viral, and antibiotic treatment ultimately diagnosed with GPA.

    We reviewed 16 cases of Wegener's granulomatosis (WG) with regard to CT findings, PR3-ANCA, and clinical courses. Because of PR3-ANCA, atypical manifestations of WG could have been diagnosed, including tiny nodules without symptoms and self-remissions. Radiologists should be aware of these atypical manifestations of WG. Seeing multiple nodules in lung, WG should be included in the differential diagnosis and extrapulmonary manifestation of WG should be evaluated. (author)

    Full Text Available A enterocolite necrosante representa uma das emergências gastrintestinais mais freqüentes e graves no período neonatal. Na suspeita clínica dessa doença, o exame radiológico simples de abdome é um procedimento de rotina, desempenhando um papel fundamental no diagnóstico, acompanhamento e detecção de complicações. No presente trabalho, realizamos uma revisão da literatura pertinente e descrevemos os achados radiológicos da enterocolite necrosante, ilustrados com casos do nosso serviço. Concluímos que o diagnóstico radiológico da enterocolite necrosante realizado em todas as suas etapas, contribui para uma conduta terapêutica imediata, reduzindo as complicações e aumentando a sobrevida dos pacientes.Necrotizing enterocolitis is one of the most frequent and severe gastrointestinal emergencies occurring in the neonatal period. Once necrotizing enterocolitis is suspected a simple abdominal x-ray is a routine examination and this film will play an essential role in the diagnosis of the disease and the follow-up care of the patient, as well as in the detection of complications. In the present study we reviewed the pertinent literature and described the radiological findings, illustrated with cases from our institution. We concluded that the radiological diagnosis of necrotizing enterocolitis done at all stages contributes for an immediate therapeutic management, reducing the complications and improving the patient's survival.

    Reversible complete atrioventricular block in patient with Wegener's granulomatosis - a report on a positive outcome with long term follow-up. Atrioventricular (AV) block is a rare complication of Wegener's granulomatosis (WG), thus there are no standards of management in such cases. We present a case of a patient with a dual-chamber pacemaker (DDD) implanted due to complete AV block in the course of Wegener's granulomatosis (WG). An immunosuppressive therapy resulted in the resolution of non-cardiac and AV conduction disorders. The diagnostic functions of the pacemaker enabled us to evaluate AV conduction over a five-year follow-up period. The resolution of AV conduction disorders, which accompanied WG remission, suggests that careful monitoring with temporary cardiac pacing may be considered in some patients before permanent pacemaker implantation.

    Orofacial granulomatosis is a chronic granulomatous condition characterized by relapsing and remitting lip swelling and oral involvement that may include deep ulcers, tags and cobblestone formation. It occurs as an independent entity but also in conjunction with systemic diseases...... such as tuberculosis, sarcoidosis and Crohn's disease. The clinical presentation is not indicative of concomitant systemic disease. To highlight the importance of thorough examination to rule out systemic disease, we present two childhood cases of orofacial granulomatosis, one of which was associated to Crohn......'s disease....

    Wegeners granulomatosis is an inflammatory systemic necrotizing idiopathic vasculitis affecting mainly small vessels. In this paper we analyzed the computed tomography findings of seven patients with Wegeners granulomatosis. The most common findings were masses and nodules (71.4%), areas of ground glass attenuation (57.1%), consolidation (42.8%), halo sign (42.8%), cavitation (42.8%), interlobular septa thickening (14.2%), bronchial wall thickening (14.2%) and pleural effusion (14.2%). Although radiological findings are mostly nonspecific, computed tomography and particularly high-resolution computed tomography are important tools in the evaluation of disease activity when evaluated in association with bronchoscopy findings and clinical data.

    Full Text Available Wegener′s granulomatosis is a serious autoimmune disorder characterized by necrotizing small-vessel vasculitis. It is a multisystem disease that primarily affects the lung and kidneys. Previous studies indicated few relapses of vasculitis after hemodialysis due to uremic immunosuppression. Our case report describes an end-stage renal failure patient who had developed non-caseating lung granulomata with giant cell formation and fibrinoid necrosis of arterial media that is consistent with Wegner′s granulomatosis for the first time and eight years after initiation of maintenance hemodialysis. We believe that such a phenomenon has rarely been reported.

Bleeding is the most frequent complication during ECMO support. Severe pre-existing bleeding has been considered a contraindication to ECMO application. Nevertheless, there are cases of successful ECMO application in patients with multiple trauma and hemorrhagic shock or head trauma and intracranial hemorrhage. ECMO has proved to be life-saving in several cases of life-threatening respiratory failure associated with pulmonary hemorrhage of various causes, including granulomatosis with polyangiitis (Wegener’s disease. We successfully applied ECMO in a 65-year-old woman with acute life-threatening respiratory failure due to diffuse massive pulmonary hemorrhage secondary to granulomatosis with polyangiitis, manifested as severe pulmonary-renal syndrome. ECMO sustained life and allowed disease control, together with plasmapheresis, cyclophosphamide, corticoids, and renal replacement therapy. The patient was successfully weaned from ECMO

    To investigate the mechanism of gallium-67 uptake in lung granulomatosis, we studied 13 rats in which lung granulomatosis was induced by injection of complete Freund adjuvant (CFA) and 14 controls. Gallium uptake was assessed in bronchoalveolar lavage fluid and lavaged lung. The cells responsible for gallium uptake were identified by latent image activation autoradiography. Gallium activity in both lavaged lungs and bronchoalveolar cells (BAC) was higher in CFA-treated animals than in controls [172,205 +/- 134,783 DPM versus 44,456 +/- 14,486 DPM +/- SD (p less than 0.05) and 40,083 +/- 16,350 DPM versus 9100 +/- 4114 DPM (p less than 0.05), respectively]. In control rats, about two-thirds of total lung gallium was located in the interstitium, whereas in CFA-treated rats it was found in the mononuclear cells of lung granulomas. Gallium tracks were more numerous in the alveolar macrophages (AM) of CFA-treated rats than in control AM (28.4 +/- 10.0/field versus 8.4 +/- 3.8/field, p less than 0.001) but the number of tracks was proportional to the number of AM (52.4 +/- 18.7 versus 12.2 +/- 4.3, respectively; p less than 0.001). It is concluded that in rats with CFA-induced lung granulomatosis 1) pulmonary gallium uptake increases, 2) mononuclear cells are responsible for this uptake in both granulomas and AM, and 3) the increased uptake is due to the increased number of mononuclear cells

One patient developed de novo 6(th) nerve palsy as an isolated relapse manifestation and the second patient a sequence of multiple cranial nerve palsies. Brain imaging...... by the overall clinical presentations. Cranial neuropathy may be the first obvious vasculitic manifestation preceding other organ disease, and since single reliable tests for its diagnosis are lacking, a multidisciplinary approach is advocated here to detect vasculitic manifestations in other organs....

    Full Text Available Abstract Wegener's granulomatosis (WG is a multi-system disease, characterised by the triad of necrotising granulomata affecting the upper and lower respiratory tracts, disseminated vasculitis and glomerulonephritis. Oral lesions are associated with up to 50% of cases, although are rare as a presenting feature. The most common oral lesions associated with WG are ulceration and strawberry gingivitis. We review the literature regarding oral manifestations of WG and present a case of lingual infarction, an extremely rare oral lesion associated with WG, in a severe, rapidly progressive and ultimately fatal form of the disease.

The disease has a predilection for the upper and lower respiratory tracts (lungs, nose, sinus, and kidneys. WG may be systemic, severe, and potentially lethal, but it may also be limited to the otolaryngological area or to the eyes and the orbits. Obstruction of the lacrimal pathway is a possible complication of the disease that affects approximately 7% of patients with WG. It usually occurs as a direct extension of sinonasal disease and typically is a late manifestation. Management of such a condition is generally viewed as difficult. We report the case of a patient with a quiescent WG limited to the otolaryngological area. This patient presented a bilateral obstruction of the nasolacrimal ducts caused by bilateral extensive adhesions in the nasal cavity. Because she had several episodes of left-side acute dacryocystitis which necessitated several courses of broad-spectrum antibiotics, she successfully underwent an endonasal endoscopic dacryocystorhinostomy using a diode laser and powered instrumentation. The authors describe the clinical case, the surgical technique, and review the literature.Keywords: Wegener’s granulomatosis, recurrent dacryocystitis, endonasal DCR, diode, laser, powered instrumentation

    Full Text Available Abstract Introduction Pulmonary talc granulomatosis is a rare disorder characterized by the development of foreign body granuloma secondary to talc exposure. Previous case reports have documented the illness in current intravenous drug users who inject medications intended for oral use. We present a rare case of the disease in a patient with a distant history of heroin abuse who presented initially with history and imaging findings highly suggestive of malignancy. Case presentation A 53-year-old man reported a 4-month history of increasing dyspnea and weight loss. He had a long history of smoking and admission chest X-ray revealed a density in the right hemithorax. Computed tomography confirmed a probable mass with further speculated opacities in both lung fields suspicious for malignant spread. Biopsies obtained using endobronchial ultrasound-guided aspiration returned negative for malignancy and showed bronchial epithelial cells with foreign body giant cell reaction and polarizable birefringent talc crystals. Conclusion This case demonstrates a rare presentation of talc granulomatosis three decades after the last likely exposure. The history and imaging findings in a chronic smoker were initially strongly suggestive of malignant disease, and we recommend that talc-induced lung disease is considered in any patient with multiple scattered pulmonary lesions and a history of intravenous drug use. Confirmation of the disease by biopsy is essential, but unfortunately there are few successful proven management options for patients with worsening disease.

    Full Text Available Histiocytic necrotizing lymphadenitis, or Kikuchi's lymphadenitis (KL, is an unusual form of lymphadenitis, generally with self-limited clinical course. KL has been reported in rare patients infected with the human immunodeficiency virus (HIV. Pathogenesis of the lesion is probably related to an impaired immune function. The purpose of the present article is to report on one case in which KL was diagnosed in an HIV-infected patient. Histomorphology and immunophenotype were similar to previous reports, but a focus of activated CD30+ macrophages was seen, what might be due to the immunological status of the patient. EBV was not detected on the sections using the in situ hybridization technique. Although rare, the occurrence of KL in HIV-infected subjects must be emphasized, because of the potential misdiagnosis of malignancy, especially in the presence of CD30+ cells.A linfadenite necrosante histiocítica, ou linfadenite de Kikuchi (LK, é uma forma rara de linfadenite, geralmente de curso clínico auto-limitado. Raros casos de LK associados à infecção pelo vírus da imunodeficiência humana (HIV foram relatados, sendo sua patogênese atribuída à disfunção imunológica destes pacientes. O objetivo do presente artigo é relatar um caso de associação de LK em um paciente HIV-positivo. A histomorfologia e a imunofenotipagem foram semelhantes aos casos anteriormente descritos na literatura, mas focos de macrófagos ativados positivos para o CD30 foram vistos, o que pode ser devido ao estado imune do paciente. A pesquisa de EBV por hibridização in situ foi negativa no tecido. Embora rara, a ocorrência de LK em pacientes HIV-positivos deve ser lembrada, por causa do potencial erro diagnóstico com linfoma maligno, especialmente na presença de células CD30+.

    2005-06-01

    A diary and an extensive correspondence of Heinrich Hertz and his family provide a meticulous documentation of his life, made available by Albrecht Folsing in 1997 through a carefully investigated biography, which permit the conclusion that H. Hertz died of Wegener's granulomatosis, 45 years before this disease had been explored. WEGENER'S GRANULOMATOSIS: The symptoms of the granulomatosis, that was first described by Friedrich Wegener in 1936 and 1939 are presented in short with literal quotations of the author: It begins with a refractory cold that will last until the end, then follow involvement of the paranasal sinuses, ears, mucous lining of mouth and pharynx, slight fever, weakness, in the final phase dissemination with nephritis, septic fever, arthritis, myalgia, paralyses leading to total immobility, exitus. The etiology is not fully understood but probably based on immunoreaction. H. HERTZ: CURRICULUM VITAE: Born in Hamburg, Germany, in 1857: after secondary school academic training in physics at Dresden, Munic and Berlin. 1885 professor of physics in Karlsruhe, then starting in 1889 at Bonn. 1887/88 exploration of the electromagnetic waves, now the basis for all radio communication, and exploration of the photoelectric effect, the basis of solar techniques. Numerous highranking distinctions. H. HERTZ: The case history is presented in detail based on numerous literal quotations from personal letters and the diary. After a few banal affections involving the teeth and toes the systemic disease became manifest in summer 1892 with a refractory cold which remained the focus of treatment until death. Granulation tissue in the nose that was excised several times: no tuberculosis, no carcinoma. Otitis with purulent mastoiditis, in October 1892 mastoidectomy, persistent purulence. Early in 1893 diagnosis of nephritis. Extraction of a superior tooth, punturing of the maxillary sinus, then twice radical opening of the maxillary sinus. Painful ankylosis and paralyses

    Full Text Available Wegener′s granulomatosis (WG is a multisystem vasculitic disorder which can commonly afflict various components of the eye. Here we describe some unusual ocular manifestations of the disease in one patient. A young male with history of upper respiratory tract symptoms including epistaxis, nasal stuffiness and maxillary sinus pain presented with bilateral lacrimal gland abscess and ptosis. Lacrimal gland biopsy revealed granulomatous vasculitis. Lung cavities, positive cytoplasmic-antineutrophil cytoplasmic antibodies and high titers of serine proteinase-3 antibodies confirmed the diagnosis of WG. The patient developed dry eyes after a month of first presentation. There was no dryness of mouth, suggesting the absence of salivary gland involvement, and antinuclear antibodies as well as antibodies against Ro and La antigens classical of primary Sjogren′s syndrome were absent. Granulomatous vasculitis of lacrimal gland leading to abscess formation and dryness of eyes has not been described in WG and reflects the aggressive nature of inflammatory process in this disease.

    2010-04-01

    Full Text Available Abstract Ataxia-telangiectasia (A-T is a complex multisystem disorder characterized by progressive neurological impairment, variable immunodeficiency and oculo-cutaneous telangiectasia. A-T is a member of chromosomal breakage syndromes and it is caused by a mutation in the ataxia-telangiectasia mutated (ATM gene. Because of a wide clinical heterogeneity, A-T is often difficult to diagnose in children. We report an unusual case of a 3-year-old boy affected by A-T who presented exclusively with extensive cutaneous granulomatosis and severe combined immunodeficiency, without neurological abnormalities, at the time of diagnosis. This case clearly emphasizes the variable presentation of A-T syndrome and highlights the difficulties in the early diagnosis of A-T. A-T should be considered in children with evidence of combined humoral and cellular immunodeficiency associated with unexplained skin granulomatous lesions, even in the absence of the classic features of this syndrome.

    Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome (CSS), is a small vessel vasculitis associated with eosinophilia and asthma. Clinical manifestations commonly seen in patients presenting with EGPA range from upper airway and lung involvement to neurological, cardiac, cutaneous, and renal manifestations. Treatment for severe presentations includes steroids, cyclophosphamide, plasmapheresis, and recently, rituximab. Rituximab is associated with a good response in the treatment of vasculitis, but a variable response for the control of allergic symptoms. Here, we report a 16-year-old female patient with severe EGPA (gastrointestinal and cutaneous vasculitis, rhinitis and asthma) refractory to conventional treatment. She was treated with rituximab, which enabled rapid control of the vasculitis component of the disease, but there was no response to rhinitis and asthma. Additionally, she developed severe bronchospasm during rituximab infusion. Sequential rituximab and omalizumab were initiated, leading to remission of all manifestations of vasculitis, rhinitis, and asthma, in addition to bronchospasm related to rituximab infusion.

    Objective To assess the Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG) with respect to its selection and weighting of items. Methods This study used the BVAS/WG data from the Wegener's Granulomatosis Etanercept Trial. The scoring frequencies of the 34 predefined items and any “other” items added by clinicians were calculated. Using linear regression with generalized estimating equations in which the physician global assessment (PGA) of disease activity was the dependent variable, we computed weights for all predefined items. We also created variables for clinical manifestations frequently added as other items, and computed weights for these as well. We searched for the model that included the items and their generated weights yielding an activity score with the highest R2 to predict the PGA. Results We analyzed 2,044 BVAS/WG assessments from 180 patients; 734 assessments were scored during active disease. The highest R2 with the PGA was obtained by scoring WG activity based on the following items: the 25 predefined items rated on ≥5 visits, the 2 newly created fatigue and weight loss variables, the remaining minor other and major other items, and a variable that signified whether new or worse items were present at a specific visit. The weights assigned to the items ranged from 1 to 21. Compared with the original BVAS/WG, this modified score correlated significantly more strongly with the PGA. Conclusion This study suggests possibilities to enhance the item selection and weighting of the BVAS/WG. These changes may increase this instrument's ability to capture the continuum of disease activity in WG. PMID:18512722

    Full Text Available La granulomatosis de Wegener (GW es una enfermedad idiopática, con posible componente autoinmune, que aparece generalmente en la quinta década de vida, caracterizándose por lesiones granulomatosas necrotizantes y vasculitis en vías aéreas y riñón. Paciente femenino de 54 años, quien desde Noviembre del 2008, presenta rinorrea, prurito y eritema en borde nasal inferior izquierdo, recibe antibióticos sin mejoría de los síntomas. En las radiografías torácicas, se observan dos radiopacidades redondeadas, de 4 cm de diámetro, sugestivas de lesiones tumorales en ambos campos pulmonares. La biopsia reporta cáncer epidermoide de alto grado, sospechándose primario en nasofaringe. Es remitida, por deterioro de condiciones, al Servicio de Neumonología del Hospital Universitario de Caracas el 18/03/2009, presentando disnea, tos productiva, placas purpúricas dolorosas en manos y pies, hipoacusia, hiperpigmentación del paladar duro, leucoplaquias y lesiones costrosas en lengua, insuficiencia renal (creatinina en 6,11 mg/dL y trombocitopenia. En TAC de tórax, se evidencian tumores mayores de 5 cm de diámetro, algunos con bordes bien definidos y otros mal delimitados con broncograma aéreo. Diagnostico definitivo de GW por serología. La GW con su afectación sistémica puede simular otras entidades como neoplasias de cabeza y cuello con metástasis pulmonares. Cuando las manifestaciones sistémicas son floridas debe sospecharse GW como diagnóstico diferencial. Palabras claves: Wegener, Granulomatosis, Vasculitis, Cáncer epidermoide.

    Full Text Available Background: Pyoderma gangrenosum (PG is caused by immune system dysfunction, and particularly improper functioning of neutrophils. At least half of all PG patients also suffer from autoimmunological diseases, one of which is Wegener granulomatosis (WG. The purpose of this article was to compare cases of patients with WG and PG in terms of their clinical course, histopathology, and applied treatment. In both, histopathological features are not fully distinct. Data from microbiological and immunological evaluation and clinical presentation are required to establish the diagnosis. We also present the case of a patient with WG and deep facial skin lesions not responding to standard treatment. Methods: Systematic review of the literature in PubMed using the search terms “Wegener granulomatosis AND Pyoderma gangrenosum” and case report. Results: The finding of 22 reports in the literature (PubMed suggests that it is a rare phenomenon. This study revealed a similar rate of comorbidity of WG and PG in both genders and an increased incidence of both diseases after the age of 50. Among skin lesions there was a dominance of ulceration, most often deep and painful, covering a large area with the presence of advanced necrosis and destruction of the surrounding tissue. The most common location proved to be the cervical-cephalic area. The most popular treatment included steroids with cyclophosphamide. Discussion: The rarity of the coexistence of these two diseases results in a lack of effective therapy. In such cases sulfone derivatives are still effective and provide an alternative to standard immunosuppression methods. Hyperbaric therapy and plasmapheresis can also play an important complementary role.

    Experimental BCG-induced granulomatosis in mice was used to study changes in the dynamics of individual liver proteoglycan components reflecting phasic extracellular matrix remodeling, determined by the host-parasite interaction and associated with granuloma development. In the early BCG-granulomatosis period, the increase in individual proteoglycan components promotes granuloma formation, providing conditions for mycobacteria adhesion to host cells, migration of phagocytic cells from circulation, and cell-cell interaction leading to granuloma development and fibrosis. Later, reduced reserve capacity of the extracellular matrix, development of interstitial fibrosis and granuloma fibrosis can lead to trophic shortage for cells within the granulomas, migration of macrophages out of them, and development of spontaneous necrosis and apoptosis typical of tuberculosis.

    Full Text Available Fasciíte necrosante é infecção bacteriana destrutiva e rapidamente progressiva do tecido subcutâneo e fáscia superficial, associada a altos índices de morbimortalidade, se não tiver tratamento precoce. Recentemente, inúmeros casos publicados têm demonstrado aumento na freqüência e gravidade dessa infecção, particularmente causada pelo Streptococcus do grupo A (GAS e que acomete até mesmo pessoas jovens e saudáveis. Classifica-se em tipo I, quando causada por flora mista de anaeróbios e outras bactérias, e tipo II, quando causada pelo GAS isolado ou associado ao Staphylococcus aureus. Os fatores predisponentes incluem: doenças crônicas e malignas, abuso de álcool, uso de drogas endovenosas, lesões da pele como varicela, úlceras crônicas, psoríase, cirurgia, traumas abertos e fechados, entre outros. Clinicamente destacam-se: a dor intensa, o edema grave, a rápida progressão e a resposta pobre à antibioticoterapia. É necessário um alto índice de suspeição para o diagnóstico clínico, que é confirmado à intervenção cirúrgica, com a evidência de necrose da fáscia superficial. Os exames radiológicos são úteis, e o diagnóstico diferencial deve ser feito principalmente com celulite em seu estágio inicial. O tratamento, que deve ser precoce, é feito com antibióticos de amplo espectro, debridamento cirúrgico agressivo e medidas de suporte clínico e nutricional.Necrotizing fasciitis is a destructive and quickly progressing bacterial infection of the subcutaneous layer and superficial fascia.

    Granulomatosis with polyangiitis (GPA) is a systemic disorder that affects small- and medium- sized vessels in many organs. Although the kidneys are the second most commonly involved organ in patients with GPA, its manifestation as multiple intrarenal aneurysms is rare. We report an unusual manifestation of GPA with multiple intrarenal microaneurysms, as demonstrated by contrast-enhanced ultrasound and computed tomography. Copyright © 2017 Elsevier Inc.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is part of antineutrophil cytoplasmic antibodies (ANCAs)-associated vasculitides. In EGPA small-vessel vasculitis is associated with eosinophilia and asthma. About 40% of EGPA patients are ANCA-positive, suggesting a role for B cells in the pathogenesis of EGPA. B cell-depleting therapy with rituximab (RTX) can be effective in ANCA-positive EGPA, but very few patients have been published to date. The role of RTX in the treatment of ANCA-negative EGPA is unclear. We report a single-center cohort of patients with eosinophilic granulomatosis with polyangiitis. Of these patients, nine (six ANCA-positive, three ANCA-negative) had been treated with RTX for relapsing or refractory disease on standard immunosuppressive treatment. In a retrospective analysis, data on treatment response, frequency of relapses, adverse events, and peripheral B-cell reconstitution were evaluated. Furthermore, serum immunoglobulin concentrations, ANCA status, and peripheral B cell subpopulations were assessed after RTX treatment. All patients had high disease activity before RTX treatment. At presentation 3 months after RTX therapy, all ANCA-positive and ANCA-negative patients had responded to RTX, with one patient being in complete remission, and eight patients being in partial remission. After a mean follow-up of 9 months, C-reactive protein concentrations had normalized, eosinophils had significantly decreased, and prednisone had been tapered in all patients. In all patients, RTX therapy was combined with a standard immunosuppressive therapy. Within the 9-month observation period, no relapse was recorded. Three patients were preemptively retreated with RTX, and during the median follow-up time of 3 years, no relapse occurred in these patients. During the follow-up of 13 patient-years, five minor but no major infections were recorded. In our analysis on nine patients with EGPA resistant to standard therapy, rituximab proved to be an

    We present a case of a 14-year-old girl who had a severe form of granulomatosis with polyangiitis (GPA) with extensive dermatological involvement, whose initial presentation was nonspecific leading to diagnostic confusion and initial consideration of infectious and other vasculitis causes. The patient presented with fever, congestion, malaise, and sinus pain. She was diagnosed with bacterial sinusitis and treated with antibiotics. Within weeks, she developed abdominal pain, hematuria, migratory arthritis, and palpable purpura and was diagnosed with Henoch-Schonlein purpura. She went on to develop hemoptysis and progression of the rash into erosive bullae. Investigations revealed that she was ANCA positive and had pauci-immune glomerulonephritis. Given her upper airway, pulmonary and renal involvement, and antineutrophil cytoplasmic antibodies positivity, a definitive diagnosis of a severe form of GPA was made. GPA is a chronic relapsing, life threatening vasculitis that predominantly affects small vessels. Our case demonstrates that GPA can present initially with nonspecific symptoms, including extensive dermatological involvement, leading to diagnostic confusion, and delays in treatment. In the case of a severe peripheral rash in the juvenile population and/or resistant upper airway symptoms, it is vital to consider a diagnosis of GPA to avoid serious organ or life threatening consequences.

    Full Text Available Wegener′s granulomatosis (WG is a necrotizing granulomatous vasculitis invol-ving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glo-merulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bila-teral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic vasculitis characterized by asthma and blood eosinophilia, with the lung being the organ most frequently affected. Oral glucocorticoids and/or immunosuppressive drugs are the mainstay therapy of EGPA. Occasional reports suggest that EGPA patients can be treated with omalizumab in addition to conventional therapy to achieve asthma control. To investigate the long-term effects of omalizumab in patients with EGPA and asthma (2 females, 3 males, age 41-64 years), we carried out a 36-month follow-up observational study. At the time of enrollment, the patients were on maintenance therapy and had moderate to severe allergic asthma, eosinophilia and rhinosinusitis. Mononeuropathy/polyneuropathy and/or histological evidence of tissue eosinophilic infiltration were also present. Patients were treated with omalizumab (300-600 mg s.c. every 2-4 weeks) as add-on therapy to prednisone, inhaled steroids and bronchodilators. During omalizumab treatment, spirometry, the asthma control test (ACT) score and eosinophilia were evaluated, and prednisone dosage was recorded. During the 36 months of omalizumab treatment asthma progressively improved as indicated by spirometry and the ACT score. Eosinophilia progressively decreased. The oral prednisone dose was reduced or withdrawn during treatment. No adverse events were recorded. In patients with EGPA and moderate to severe allergic asthma, omalizumab can be beneficial and safe. It enables corticosteroid tapering while decreasing eosinophilia and improving asthma symptoms over 36 months.

    Heart involvement is the leading cause of death of patients with eosinophilic granulomatosis with polyangiitis (EGPA; formerly Churg-Strauss syndrome) and is more frequent in anti-neutrophil cytoplasm antibody (ANCA)-negative patients. Post-transplant outcome has only been reported once. We conducted a retrospective international multicenter study. Patients satisfying the criteria of the American College of Rheumatology and/or revised Chapel Hill Consensus Conference Nomenclature were identified by collaborating vasculitis and transplant specialists, and the help of the Churg-Strauss Syndrome Association. Nine ANCA(-) patients who received transplants between October 1987 and December 2009 were identified. The vasculitis and cardiomyopathy diagnoses were concomitant for 5 patients and separated by 12 to 288 months for the remaining 4 patients. Despite ongoing immunosuppression, histologic examination of 7 (78%) patients' explanted hearts showed histologic patterns suggestive of active vasculitis. The overall 5-year survival rate was low (57%), but rose to 80% when considering only the 6 patients transplanted during the last decade. After survival lasting 3 to 60 months, 4 (44%) patients died sudden deaths. The search for EGPA-related cardiomyopathy is mandatory early in the course of this type of vasculitis. Indeed, prompt treatment with corticosteroids and cyclophosphamide may achieve restore cardiac function. Most patients in this series were undertreated. For patients with refractory EGPA, heart transplantation should be performed, which carries a fair prognosis. No optimal immunosuppressive strategy has yet been identified.

    The prevalence of eosinophilic granulomatosis with polyangiitis (EGPA; previously known as Churg-Strauss syndrome) is lower than that of other antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV's), and only a few randomized controlled trials have been conducted for this rare disease. However, recent international efforts have helped delineate the best treatment approach. At present, EGPA conventional therapy is by default similar to that of other AAVs. Limited, non-severe EGPA can initially be treated with glucocorticoids (GCs) alone. Patients with life-threatening manifestations and/or major organ involvement must receive a combination of GCs and an immunosuppressant, mainly cyclophosphamide. Remission can be achieved in >85% of patients with these first-line treatments, but vasculitis relapses occur in more than one-third of patients, and about 85% cannot stop GC treatment because of GC-dependent asthma and/or ENT manifestations. A few biologic agents, including rituximab or mepolizumab, are now under investigation after interesting preliminary results. Expert commentary: Treatment for EGPA still has several unmet needs. Several biologic agents are now under investigation in randomized controlled trials, but a few others should be considered soon. Their benefit should be demonstrated for devising more EGPA-tailored therapeutic strategies (ideally GC-free).

    Full Text Available Systemic vasculitides (SVs are characterized by inflammation of the blood vessels wall; the spectrum of their clinical manifestations depends on the type, extent, and location of affected vessels and the activity of systemic inflammation. The etiology of most primary SVs is unknown. Antineutrophil cytoplasmic antibodies (ANCAs are implicated in its pathogenesis. The presence of ANCAa in patients' serum and the correlation of their level with the severity of clinical manifestations served as a basis for identifying a subgroup of systemic necrotizing vasculitides associated with ANCA synthesis: granulomatosis with polyangiitis (GPA, microscopic polyangiitis, and Churg – Strauss syndrome. GPA is characterized by systemic granulomatous necrotizing vasculitis involving the small vessels of the upper respiratory tract, lung, and kidney.The paper describes a case of difficult diagnosis and successful rituximab (RTM treatment of generalized GPA in a 45-year-old female patients. The disease occurred with local damage to the upper respiratory tract, granulomatous inflammation of the pulmonary vessels to form multiple infiltrates with lung tissue destruction elements and necrotizing glomerulonephritis. Despite intensive immunosuppressive treatment, there was a rapid GPA progression with the further development of respiratory failure, which had been induced by stenotic laryngitis subglottica leading to tracheostoma. Damage to the organ of vision could lead to severe complications, including amaurosis. RMT was shown to be effective in treating generalized GPA with a poor prognosis.

    Full Text Available Previous studies suggest a role for eotaxin-3, TARC/CCL17 and IgG4 in newly-diagnosed patients with eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss with highly active disease. The role of these biomarkers in relapsing disease is unclear.Serum levels of TARC/CCL17, eotaxin-3, IgG4, and IgG4/IgG ratio were determined in serum samples from a longitudinal cohort of patients with EGPA (105 visits of 25 patients. Epidemiological, clinical and laboratory data were available for all visits.At the first visit, 80% of patients were using glucocorticoids and 68% additional immunosuppressive drugs. Disease flares were seen at 18 visits. The median BVAS and BVAS/WG scores at time of relapse were 4 and 2, respectively. None of the biomarkers tested were useful to discriminate between active disease and remission. Patients treated with prednisone had lower eotaxin-3 and eosinophil levels compared to patients not taking glucocorticoids irrespective of disease activity. Use of immunosuppressive agents was not associated with biomarker levels.Serum levels of TARC/CCL17, eotaxin-3, IgG4, and IgG4/IgG ratio do not clearly differentiate active and inactive disease in established EGPA. Defining biomarkers in EGPA remains a challenge especially during times of glucocorticoid use.

    Full Text Available The Eosinophilic Granulomatosis with Polyangiitis (formerly Churg- Strauss Syndrome (EGPA is a systemic inflammatory disease characterized by the presence of rhinitis, asthma, peripheral eosinophilia, and vasculitis—the latter being characteristic of the late stage of the disease. After several years from the onset of the disease, small- and medium-sized vessel vasculitis ensues, undertaking various organs and systems. Upper and lower airways, skin, nervous system, gastrointestinal tract, heart, and kidneys are the most commonly involved organs. It is believed that tissue injury is the result of processes mediated by antineutrophil cytoplasmic antibody (ANCA, or toxic mediators released by eosinophils. Although it is classified as ANCA-associated vasculitis, these autoantibodies are present in only 40% of cases. The authors report the case of a patient with EGPA, who had a history of asthma, peripheral and central neuropathy, palpable purpura, gastrointestinal micro perforation, peripheral eosinophilia, and the presence of myeloperoxidase-antineutrophil cytoplasmic antibody. Inflammatory parameters improved after the initiation of treatment, but 1 month after hospital discharge the patient developed symptoms compatible with pulmonary embolism and died. Thrombophilia that occurs in EGPA is due to the interaction between the inflammatory response and eosinophilia with the clotting system resulting in a pro-thrombotic state. Although not yet well-determined, the authors call attention to the possibility of the impact of thromboembolic events on the prognosis of patients with EGPA. In addition to the adequate immunosuppressive treatment, prophylaxis and treatment for thrombosis should never be overlooked.

    We report surgical treatment of a patient with dacryocystitis and retinal detachment (RD), which are rare ophthalmic involvements of Wegener granulomatosis (WG). The patient was a 26-year-old man with WG. He was diagnosed as having WG 4 years ago and he has been treated by maintenance doses of predonisolone and cyclophosphamide. Rheumatoid factor and serum antinuclear antibody were negative. Cytoplasmic pattern-antineutrophil cytoplasmic antibody (C-ANCA) and renal function were normal. He was found to have nasolacrimal duct obstruction and lattice degeneration bilaterally, retinal tear with RD in the left eye and tear without RD in the right eye. No sign of vasculitis was found in fluorescein angiography. Bilateral dacryocystorhinostomy was performed without any sign of postoperative necrosis of the wound. After the surgery, epiphora and eye discharge disappeared and lacrimal passage has been maintained without obstruction. The pathological findings of his nasal mucosa and lacrimal sac showed chronic inflammation and no typical changes of WG. There was no abnormal change in the conjunctiva and sclera after an uncomplicated scleral buckling surgery. We conclude that operations such as dacryocystorhinostomy and scleral buckling surgery may be performed successfully when WG is controlled within the normal limits of C-ANCA.

    Full Text Available Eosinophilic granulomatosis with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome, is a rare systemic disease situated between primary small vessel vasculitides associated with antineutrophil cytoplasmic antibodies (ANCAs and hypereosinophilic syndromes (HES. Here, we present a case of EGPA in a 38-year-old male, with a previous diagnosis of asthma, who presented with fever, migratory lung infiltrates and systemic eosinophilia that was refractory to previous courses of antibiotics. This case highlights the importance of the primary care physician understanding the differential diagnosis of pulmonary eosinophilic syndromes.

    Full Text Available Background: Upper airway compromise due to tracheobronchial stenosis commonly occurs in patients with Wegener's Granulomatosis (WG. There is at present no consensus on the optimal management of this life-threatening condition. Objective: To assess the results of laryngo-tracheo-bronchoscopy, intralesional steroid therapy, laser surgery, and dilatation in managing obstructive tracheobronchial WG. Methods: Records of eighteen previously-untreated stridulous patients with obstructive tracheobronchial WG, treated between 2004 and 2006 were prospectively recorded on an airway database and retrospectively reviewed. Information about patient and lesion characteristics and treatment details were recorded. Treatment progress was illustrated using a timeline plot, and intervention-free intervals were calculated with actuarial analysis. Results: There were nine males and the average age at presentation was 40 (16 years [range 13–74]. There were thirteen patients with tracheal, and five patients with tracheal and bronchial lesions. The average tracheal lesion height was 8 (3 mm, located 23 (9 mm below the glottis. There were 1, 10 and 7 Myer-Cotton grade I, II and III lesions respectively. Mean intervention-free interval following minimally-invasive treatment was 26 (2.8 months. Following endobronchial therapy the median intervention-free interval was 22 months (p>0.8 vs. tracheal lesions. No patient required a tracheostomy or endoluminal stenting. Conclusions: Intralesional steroid therapy and conservative endoluminal surgery is an effective strategy for treating airway compromise due to active tracheal and bronchial WG, obviating the need for airway bypass or stenting. We recommend the combination of endotracheal dilatation, conservative laser surgery and steroid therapy as the standard of care for treating airway compromise due to obstructive tracheobronchial WG.

  12. Diagnosis and classification of eosinophilic granulomatosis with polyangiitis (formerly named Churg-Strauss syndrome).

    Mouthon, Luc; Dunogue, Bertrand; Guillevin, Loïc

    2014-01-01

    Recently, a group of experts in the field suggested to rename Churg-Strauss syndrome as eosinophilic granulomatosis with polyangiitis (EGPA). This condition, first described in 1951, is a rare small- and medium-sized-vessel vasculitis characterized by an almost constant association with asthma and eosinophilia, and, by the presence of anti-myeloperoxidase (MPO) antineutrophil cytoplasm antibodies (ANCA) in 30-38% of the patients. Vasculitis typically develops in a previously asthmatic and eosinophilic middle-aged patient. Asthma is severe, associated with eosinophilia and extrapulmonary symptoms. Most frequently EGPA involves the peripheral nerves and skin. Other organs, however, may be affected and must be screened for vasculitis, especially those associated with a poorer prognosis, such as the heart, kidney and gastrointestinal tract, as assessed by the recently revised Five-Factor Score (FFS). Recent insights, particularly concerning clinical differences associated with ANCA status, showed that EGPA patients might constitute a heterogeneous group. Thus, EGPA patients with anti-MPO ANCA suffered more, albeit not exclusively, from vasculitis symptoms, such as glomerulonephritis, mononeuritis multiplex and alveolar hemorrhage, whereas ANCA-negative patients more frequently develop heart involvement. This observation led to the hypothesis that EGPA might be divided into different clinical and pathophysiological subtypes, which could be managed better with more specifically adapted therapies. For now, EGPA treatment still relies mainly on corticosteroids and, when necessary for patients with poorer prognoses, combined immunosuppressant drugs, especially cyclophosphamide. Overall survival of EGPA patients is good, despite not uncommon relapses. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The objective of the study was to systematically assess aortic inflammation in patients with granulomatosis with polyangiitis (GPA) using {sup 18}F-2-deoxy-2-[{sup 18}F]fluoro-D-glucose (FDG) positron emission tomography (PET)/CT. Aortic inflammation was studied in PET/CT scans obtained from 21 patients with GPA; 14 patients with sarcoidosis were included as disease controls, 7 patients with stage I or II head and neck carcinoma ascertained during routine clinical practice were used as healthy controls (HC) and 5 patients with large vessel vasculitis (LVV) were used as positive controls. Aortic {sup 18}F-FDG uptake was expressed as the blood-normalized maximum standardized uptake value (SUV{sub max}), known as the target to background ratio (mean TBR{sub max}). The mean TBR{sub max} (interquartile range) of the aorta in patients with GPA, sarcoidosis, HC and LVV were 1.75 (1.32-2.05), 1.62 (1.54-1.74), 1.29 (1.22-1.52) and 2.03 (1.67-2.45), respectively. The mean TBR{sub max} was significantly higher in patients suffering from GPA or LVV compared to HC (p < 0.05 and p < 0.005, respectively) and tended to be higher in patients suffering from sarcoidosis, but this did not reach statistical significance (p = 0.098). The mean TBR{sub max} of the most diseased segment was significantly higher compared to HC [1.57 (1.39-1.81)] in LVV patients [2.55 (2.22-2.82), p < 0.005], GPA patients [2.17 (1.89-2.83), p < 0.005] and patients suffering from sarcoidosis [2.04 (1.88-2.20), p < 0.05]. In GPA patients, the mean TBR{sub max} of the aorta was significantly higher in patients with previous renal involvement [2.01 (1.69-2.53)] compared to patients without renal involvement in the past [1.60 (1.51-1.80), p < 0.05]. Interrater reproducibility with a second reader was high (all intraclass correlation coefficients >0.9). Patients suffering from GPA show marked aortic FDG uptake. (orig.)

    Full Text Available The Necrotizing enterocolitis (NEC is a serious illness of the newborn that affects mainly the preterm infant. It corresponds to a diffuse intestinal necrosis with more affection of the ileocecal region. The pathophysiology is complex and multiple risk factors can cause the illness in a susceptible infant. Among the different theories about their appearance is observed that prematurity, intestinal isquemia, bacterial colonization and enteral feeding are the main risk factors, which can be favored by prenatal, perinatal or postnatal conditions. The aim of this article is to review the pathophysiology and the risk factors described in the current evidence. La enterocolitis necrosante (ECN es una grave enfermedad propia del recién nacido (RN que afecta principalmente a los RN pretérmino (RNPT. Corresponde a una necrosis isquémica de la mucosa intestinal con mayor afección de la región ileocecal. La fisiopatología es compleja y en ella participan múltiples factores de riesgo que pueden ocasionar la enfermedad en un RN susceptible. Entre las diferentes teorías acerca de su aparición se observa reiteradamente que la prematuridad, la isquemia intestinal, la colonización bacteriana y la alimentación enteral se repiten como los factores de riesgo principales, los cuales pueden ser favorecidos por condiciones prenatales, perinatales o posnatales. Se revisan la fisiopatología y los factores de riesgo implicados en la génesis de esta enfermedad.

    Previous reports of combined allergic bronchopulmonary mycosis (ABPM) and eosinophilic granulomatosis with polyangiitis (EGPA) are limited; however, among 41 cases of ABPM and 18 cases of EGPA treated at our hospital, we experienced three cases of combined ABPM and EGPA. In two of these cases, the diagnosis of EGPA preceded that of ABPM, however, one of the two cases had already shown findings suggestive of ABPM, such as mucous plugs and central bronchiectasis, at the time of the diagnosis of EGPA. In six previously reported cases of combined ABPM and EGPA, ABPM preceded EGPA in four cases. In the other two cases in which EGPA was diagnosed before or simultaneously with ABPM, findings suggestive of ABPM had been detected when EGPA was diagnosed, which suggests that sensitization to fungi resulting in ABPM may play an important role in the development of EGPA. Careful attention should therefore be paid to the possibility that these diseases may coexist during the course of either disease.

  1. The use of abatacept in debilitating cavitating lung disease associated with rheumatoid arthritis, bronchocentric granulomatosis and aspergillosis.

    Neff, K

    2010-06-01

    A case of debilitating cavitating lung disease associated with rheumatoid arthritis and bronchocentric granulomatosis, which failed to respond to conventional medical or surgical treatment, is described. The patient was treated over 10 years with steroids, antimicrobial agents, disease-modifying antirheumatoid drugs and surgery. Lung function continued to decline and the patient presented for admission with recurrent pneumonia. Abatacept was initiated to modify the underlying immunopathology. Following 12 months of treatment with abatacept the patient has demonstrable improvement in lung function and lung anatomy, and has not presented to hospital with pneumonia. She has tolerated the treatment without complication. The use of abatacept has stabilised the lung disease in this case in the medium term and prevented readmission to hospital. These results suggest a larger role for abatacept in those with such disease in the future and may warrant further investigation.

    We report a case of eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome) complicated by perforation of the small intestine and necrotizing cholecystitis. A 69-year-old man with a history of bronchial asthma was admitted with mononeuritis multiplex. The laboratory findings included remarkable eosinophilia. He was treated with corticosteroids and his laboratory indices showed improvement; however, his functional deficits remained. His neuropathy gradually improved after the addition of intravenous immunoglobulin (IVIG). He was subsequently treated with oral prednisolone (40 mg/day) as maintenance therapy. Within a month after finishing IVIG, he developed perforation of the small intestine and necrotizing cholecystitis. Intestinal perforation has often been reported as a gastrointestinal complication of EGPA. In contrast, cholecystitis is a rare complication. We report this case because the manifestation of more than one complication is extremely rare. Gastrointestinal symptoms may be a complication of EGPA itself and/or immunosuppressive treatment.

    PURPOSE: To evaluate pulmonary pathologies in Wegener granulomatosis with sequential computed tomography (CT) in order to differentiate active inflammatory lesions from chronic fibrotic lesions. MATERIAL AND METHODS: Serial CT findings in 38 patients with Wegener granulomatosis were retrospectively analyzed (mean follow-up period, 21 months). The presence, extension, and distribution of the following findings were evaluated with CT: parenchymal nodules, masses, ground-glass attenuation, airspace consolidation, bronchial wall-thickening, bronchiectasis, linear areas of attenuation, pleural irregularities, pleural effusions, hilar and mediastinal lymphadenopathy. RESULTS: Observed in 92% of patients, nodules were the most common CT pathology. Areas of ground-glass attenuation, consolidation, masses of linear attenuation, and tracheal/bronchial wall-thickening were detected in 24%, 26%, 32%, 39%, and 68% of patients. At follow-up, the clearance of lesions was most consistent for areas of ground-glass attenuation (89%), masses (87%), and cavitated nodules (85%). In the follow-up scan, 58% of all nodules, 47% of pulmonary consolidations, and 66% of bronchial wall-thickening were completely resolved. Areas of bronchiectasis and septal/non-septal lines remained stable in 70% and 71% of patients. CONCLUSION: The majority of the lesions decreased or resolved completely with or without areas of linear attenuation. Ground-glass attenuation, cavitated nodules and masses appear to represent active inflammatory lesions. In most probability, areas of bronchiectasis and septal/non-septal lines more often represent chronic fibrotic changes rather than active inflammatory changes. In combination with clinical evaluation and bronchoscopy, CT assists in the assessment of disease activity

    We conducted a cross-sectional nationwide survey to determine eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA) prevalence and clinical features in Japan. Data for EGPA patients in 2008 were collected from 1,564 hospitals. In total, 965 patients were reported from 365 departments. In a second survey, clinical data for 473 patients were obtained. We estimated that 1,866 (95% CI: 1,640-2,092) patients have EGPA in Japan (prevalence, 17.8/1,000,000). Of the 473 patients in the second survey, 315 fulfilled American College of Rheumatology (ACR) criteria or Lanham's criteria for EGPA. The mean age (± SD) of the 315 at onset was 55 ± 14 years, male to female ratio 1:2. 93% of patients had neurological manifestations, which were the organ system most frequently involved. Among 277 patients tested for myeloperoxidase (MPO)-/p anti-neutrophil cytoplasmic antibody (ANCA), 139 (50%) were positive, while only 6 of 238 were positive for proteinase3 (PR3)-/cANCA. MPO-ANCA-positive patients had renal involvement, mucous membrane or ophthalmological symptoms, and ENT symptoms more frequently, whereas cutaneous lesions and cardiovascular involvement were less common. The prevalence of EGPA and the frequency of MPO-/p-ANCA-positivity in Japanese EGPA patients were mostly similar to those of Western countries. However, female predominance and a high frequency of neurological manifestations characterized Japanese patients.

    Introduction Chemokine receptors play an important role in mediating the recruitment of T cells to inflammatory sites. Previously, small proportions of circulating Th1-type CCR5+ and Th2-type CCR3+ cells have been shown in granulomatosis with polyangiitis (GPA). Wondering to what extent CCR4 and CCR6 expression could also be implicated in T cell recruitment to inflamed sites in GPA, we investigated the expression of CCR4 and CCR6 on T cells and its association with T cell diversity and polari...

    Eosinophilic granulomatosis with polyangiitis (EGPA), which was previously called Churg-Strauss syndrome, is a necrotizing systemic vasculitis of unknown cause accompanied by prominent eosinophilia. Cardiovascular complications, including eosinophilic myocarditis, are a major cause of mortality in this disorder. Acute pericarditis with slight pericardial effusion is a typical manifestation in EGPA, though hemodynamically significant pericardial effusion has been reported in a few cases. We report a case that initially presented with isolated cardiac tamponade, which was followed by systemic manifestations of EGPA over 3 weeks. Including the present case, previous EGPA cases with cardiac tamponade are reviewed to delineate its clinical characteristics.

    The purpose of this study was to determine to what extent high-resolution computed tomography (HRCT) of the lungs can distinguish active inflammatory disease from inactive cicatricial disease in patients treated for Wegener's granulomatosis (WG). Twenty-eight WG patients with active pulmonary disease underwent a first HRCT examination immediately before standard immunosuppressive treatment and a second examination after clinical remission had been achieved. Lesions remaining after treatment were categorized as residual damage and were compared with findings during active disease to see by what features active and cicatricial disease can be distinguished. During active disease 17 patients had nodules/masses, 12 had ground-glass opacities, 6 had septal lines and 6 had non-septal lines. After treatment, ground-glass opacities had resolved completely. Nodules/masses had resolved in 8 patients and had diminished in 7 patients. Residual nodules were distinguished from nodules/masses in active disease by lack of cavitation and a diameter of mostly <15 mm. In one-third of patients lines resolved, but in 8 instances new lines evolved during immunosuppression. During a follow-up period of a median 26.5 months (range 20.0-33.8), patients with residual nodules or lines had no more relapses than patients with completely cleared lungs. Treated pulmonary WG leaves substantial residual damage. High-resolution CT does assist in the distinction between active and inactive lesions. Ground-glass opacities, cavitating nodules/masses and masses measuring more than 3 cm represent active disease ordinarily. Non-cavitary small nodules and septal or non-septal lines can be either active or cicatricial lesions. The nature of these lesions needs to be clarified by longitudinal observation. (orig.)

    To investigate the risk factors and treatment strategies for pneumothorax secondary to granulomatosis with polyangiitis (GPA). Retrospective analysis of cases with pneumothorax secondary to GPA from our own practice and published on literature. A total of 25 patients, 18 males and 7 females, mean age 44 ± 15.7 years, were analyzed. Diagnosis included pneumothorax (11 cases), hydropneumothorax (n = 5), empyema (n = 8) and hemopneumothorax (n = 1). 88% (22/25) patients showed single/multiple pulmonary/ subpleural nodules with/without cavitation on chest imaging. Erythrocyte sedimentation rate and C-reactive protein were both elevated. Corticosteroids and immunosuppressive agents were used in 16 cases. Five cases received steroid pulse therapy, of which 4 patients survived. Pleural drainage was effective in some patients. Seven patients underwent surgical operations. In the 10 fatal cases, infection and respiratory failure were the most common cause. Lung biopsy/ autopsy showed lung/pleural necrotizing granulomatous vasculitis, breaking into the chest cavity, pleural fibrosis, bronchial pleural fistula, etc. The mean age in the death group was greater than the survival group (53 ± 12.9 years vs 40.1 ± 14.7 years, p = 0.05), the ineffective pleural drainage was also higher in the death group (5/5 vs 0/7, p = 0.01). Pneumothorax was seen in the active GPA, due to a variety of reasons, and gave rise to high fatality rate. Aggressive treatment of GPA can improve the prognosis. Older and lack of response for pleural drainage indicates poor prognosis.

    Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is an antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis characterized by a history of asthma, hypereosinophilia. The prevalence of ANCA in EGPA is less common than in other ANCA-associated vasculitis. Increasing evidence of complement activation in the pathogenesis of ANCA-associated vasculitis has been provided by studies in animal models. We examined EGPA patients with cutaneous manifestations as an initial sign and investigated the correlations among clinical, serological and histopathological findings. We focused on differences among ANCA, blood urea nitrogen and complement levels such as complement 3 (C3), C4 and total complement hemolytic activity (CH50). We retrospectively investigated the records of 22 patients (11 male and 11 female) with EGPA admitted to our hospital from 1997-2012. Ten of the 22 patients (46%) were positive for serum myeloperoxidase (MPO)-ANCA. In contrast, all the patients were negative for serum proteinase 3 ANCA. There was a significantly positive correlation between serum CH50 and C4 levels in patients with EGPA. Serum blood urea nitrogen (BUN) levels differed significantly between MPO-ANCA-positive and -negative patients. Serum CH50 levels were higher in MPO-ANCA-positive patients compared to negative patients. Serum BUN levels were higher in elevated CH50 patients compared to normal and low CH50-negative patients. We propose that positive findings for MPO-ANCA with CH50 high activity may be a risk factor for developing renal insufficiency. Assuming there are correlations between the presence of ANCA and complements, earlier diagnosis based on initial efficacious treatment for EGPA. © 2013 Japanese Dermatological Association.

    To date only 38 cases of childhood-onset eosinophilic granulomatosis with polyangiitis (cEGPA; formerly Churg-Strauss syndrome) have been reported. Additional patients with cEGPA could enhance the understanding of this rare and life-threatening condition. Our objectives were (1) to determine the frequency of specific organ system involvement; (2) to examine initial therapeutic regimen; and (3) to document disease and therapy-related morbidity in a contemporary cohort of patients with cEGPA. Retrospective review of patients evaluated at the Cleveland Clinic between 2003 and 2011 who met either American College of Rheumatology or Lanham criteria for EGPA and whose age was < 18 years at symptom onset. Nine patients (8 female; 7 white) were identified. Median age at onset of rhinitis/asthma symptom was 13 years and median age at diagnosis of cEGPA was 15 years. All patients demonstrated eosinophilia, upper airway disease (allergic rhinitis, chronic sinusitis, and/or nasal polyps), and pulmonary involvement. Other frequently involved organ systems included musculoskeletal (67%), gastrointestinal (67%), cutaneous (67%), neurologic (56%), and cardiac (44%). Antineutrophil cytoplasmic antibody (ANCA) serologies were negative in all patients. The medications used most frequently for initial therapy included oral (44%) or intravenous corticosteroids (56%) and azathioprine (67%). Disease or therapeutic complications occurred in half of the cohort and included heart failure, stroke, and sequela from longterm, high-dose steroids. Eosinophilia, in combination with upper airway, pulmonary, musculoskeletal, neurologic, and cardiac manifestations, is frequently observed in cEGPA. ANCA titers are often negative. Steroids are the mainstay of initial therapy but steroid-related side effects occur regularly.

    Full Text Available The purpose of this study was to determine the prevalence of enteric bacteria and yeasts in biofilm of 80 HIV-positive patients with plaque-associated gingivitis or necrotizing periodontitis. Patients were subjected to extra, intra oral and radiographic examinations. The oral hygiene, bleeding on probing, gingival conditions, and attachment loss were evaluated. Clinical specimens were collected from gingival crevices or periodontal pockets, transferred to VMGA III, diluted and transferred to Sabouraud Dextrose agar with 100 µg/ml of chloramphenicol, peptone water, EVA broth, EMB agar, SS agar, Bile esculin agar and Brilliant green agar. Isolation of yeasts was carried out at room temperature, for 3-7 days; and for the isolation of enteric microorganisms plates were incubated at 37ºC, for 24-48 h. The yeasts identification was performed according to the carbon and nitrogen assimilation, fermentation of carbohydrates and germ tube formation. Bacteria were identified according to their colonial and cellular morphologies and biochemical tests. Yeasts were identified as Candida albicans and its occurrence was more common in patients with CD4+ below 200/mm³ and was affected by the extension of periodontal involvement (P = 0.0345. Enteric bacteria recovered from clinical specimens were identified as Enterobacter sakazakii, Enterobacter cloacae, Serratia liquefaciens, Klebsiella oxytoca and Enterococcus sp. Enterobacteriaceae and enterococci were detected in 32.5% of clinical samples from patients with necrotizing periodontitis. In conclusion, non-oral pathogenic bacteria and C. albicans were more prevalent in periodontal sites of HIV-positive patients with necrotizing periodontitis and chronic gingivitis.O objetivo desse estudo foi avaliar a ocorrência de bactérias entéricas e leveduras no biofilme subgengival de pacientes HIV-positivos com gengivite crônica ou periodontite necrosante.

    Experiments on the model of mouse BCG-induced granulomatous showed that the content of glycosaminoglycans and proteoglycans in the extracellular matrix of the liver and lungs are changed at the early stages of inflammation (days 3 and 30 postinfection) before cell destruction in the organs begins. This is related to degradation of extracellular matrix structures. Their high content in the blood and interstitium probably contributes to the formation of granulomas, fibroblast proliferation and organ fibrosis. These processes depend on the infection route that determines different conditions for generalization of the inflammation process. Intravenous method of vaccine injection is preferable to use when designing the experiments simulating tuberculosis granulomatosis, especially for the analysis of its early stages.

    Omalizumab is a monoclonal anti-immunoglobulin E antibody used for the treatment of severe perennial allergic asthma. Previous reports have suggested that omalizumab treatment can be associated with the development of eosinophilic granulomatosis with poliangiitis (EGPA) (formerly known as Churg-Strauss syndrome) and an increased risk of malignancy. Long-term risks of omalizumab treatment are not very well defined. Here, we report the case of a 75-year-old woman with concurrent occurrence of EGPA and brain tumor after more than 7 years of omalizumab treatment. The possibility of EGPA should be borne in mind during long-term treatment with omalizumab. Despite the absence of definitive data, an association may also exist between the development of malignancy and omalizumab use. © The Author(s) 2015.

    Lymphomatoid granulomatosis (LYG) is a very rare Epstein-Barr virus (EBV) associated B-cell lymphoproliferative disorder. We report the case of a 41-year-old man who presented with fever and respiratory symptoms. Computed tomography showed multiple nodules in both lung fields. Polymerase chain reaction (PCR) analysis for EBV was positive in bronchoalveolar lavage and biopsy of lung node yielded a diagnosis of LYG, grade III. Shortly after initiation of treatment with agressive chemotherapy, neurological deterioration appeared. Neuroimaging findings revealed hydrocephalus and PCR analysis of the cerebrospinal fluid (CSF) was positive for EBV. Treatment with intravenous rituximab led to rapid reduction of EBV load in CSF, along with clinical and radiological improvement. After completion of treatment with immunochemotherapy, an autologous stem cell transplantation was performed. Patient stays in remission 18 months after diagnosis.

    Full Text Available Sarcoid like reaction is a well-known entity that occurs as a consequence to several malignancies or their therapies. Immunotherapy has gained a lot of interest in the past few years and has recently gained approval as first line therapy in multiple advanced stage malignancies. Pneumonitis has been described as complication of such therapy. Granulomatous inflammation has been only rarely reported subsequent to immunotherapy. We describe a case of granulomatous inflammation reactivation affecting the lungs in a patient previously exposed to Pembrolizumab and have evidence of a distant granulomatous infection. We discuss potential mechanisms of the inflammation and assert the importance of immunosuppression in controlling the dis-inhibited immune system.

    Full Text Available We report the history and clinical presentation of an 88-year-old female with Fuchs dystrophy who developed an acute anterior necrotizing scleritis in her left eye 23 months after an uncomplicated combined penetrating keratoplasty and phacoemulsification with intraocular lens implantation which progressed to slceral perforation with uveal prolapses. The patient underwent a complete systemic work-up for both autoimmune and infectious causes of scleritis. Surgical specimens of the area of scleral perforation were sent for histology and microbiologic studies. Analysis of surgical specimens revealed the presence of culture-proven Nocardia asteroides as a causative agent for the patient's scleral perforation. Results of her systemic autoimmune work-up were not conclusive. Successful treatment with tectonic scleral reinforcement with donor corneal tissue and preserved pericardium, oral and topical trimethoprim-sulfamethoxazole and topical amikacin salvaged the globe and increased vision. The patient's final best-corrected visual acuity sixteen months after her last operation remains 20/70. Prompt surgical intervention with submission of appropriate specimens for pathological diagnosis and microbiology, along with consultation with rheumatologic and infectious disease specialists, are mandatory to minimize visual loss in cases of suspected infectious necrotizing scleritis.Relato de caso de esclerite necrosante aguda, evoluindo para perfuração escleral com prolapso uveal, 23 meses após procedimento de ceratoplastia penetrante e facoemulsificação com implante de lente intra-ocular no olho esquerdo sem intercorrências.A paciente foi submetida à avaliação completa auto-imune para esclerite.

    Full Text Available We report a rare case of granulomatosis with polyangiitis (GPA presenting with hypertrophic cranial pachymeningitis (HCP, abducens nerve palsy, and stenosis of the internal carotid artery (ICA. A 59-year-old Japanese man presented with a year history of nasal obstruction and a 2-month history of slight headache. Histopathological examination of the granulomatous mucosa in the ethmoid sinuses resected by endoscopic sinus surgery revealed necrotizing vasculitis with multinucleated giant cells. The patient was diagnosed with the limited form of GPA as a result of the systemic examination. He declined immunosuppressive treatment. Eighteen months after the diagnosis of GPA, he presented with diplopia and severe headache. Though nasal findings indicating GPA were not observed in the nasal cavity, CT scan revealed a lesion of the right sphenoid sinus eroding the bone of the clivus. Gadolinium-enhanced MRI of the brain showed thickening of the dura mater around the right cavernous sinus and clivus. Magnetic resonance angiography and cerebral angiography revealed narrowing at the C5 portion of the ICA. Intravenous methylprednisolone pulse therapy followed by oral prednisolone and cyclophosphamide resolved headache and dramatically improved HCP and stenosis of the ICA.

    2012-01-01

    Full Text Available Granulomatosis with polyangiitis (Wegener’s (GPA may mimic IgG4-related disease (IgG4-RD on histologic examination of some biopsies, especially those from head and neck sites. IgG4 immunostain is often performed in this context for differential diagnosis with IgG4-RD. However, the prevalence of IgG4+ cells in GPA has not been explored. We examined the IgG4+ cells in 26 cases confirmed as GPA by a thorough clinical and pathologic assessment. Twenty-six biopsies consisted of 14 sinonasal/oral cavity/nasopharynx, 7 orbit/periorbital, 3 lung/pleura, 1 iliac fossa/kidney, and 1 dura specimens. Eight of 26 (31% biopsies revealed increased IgG4+ cells (>30/HPF and >40% in IgG4+/IgG+ ratio. The IgG4+ cells and IgG4+/IgG+ ratio ranged 37–137/hpf and 44–83%, respectively. Eight biopsies with increased IgG4+ cells were from sinonasal (n=4 or orbital/periorbital (n=4 sites. In conclusion, increased IgG4+ cells are not uncommonly seen in sinonasal or orbital/periorbital biopsies of GPA, which could pose as a diagnostic pitfall.

    Eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome) is a rare systemic vasculitis and is difficult to diagnose. EGPA has a number of symptoms including peripheral dysesthesia caused by mononeuropathy multiplex, which is similar to radiculopathy due to lumbar disc hernia or lumbar spinal stenosis. Therefore, EGPA patients with mononeuropathy multiplex often visit orthopedic clinics, but orthopedic doctors and spine neurosurgeons have limited experience in diagnosing EGPA because of its rarity. We report a consecutive series of patients who were initially diagnosed as having lumbar disc hernia or lumbar spinal stenosis by at least 2 medical institutions from March 2006 to April 2013 but whose final diagnosis was EGPA. All patients had past histories of asthma or eosinophilic pneumonia, and four out of five had peripheral edema. Laboratory data showed abnormally increased eosinophil counts, and nerve conduction studies of all patients revealed axonal damage patterns. All patients recovered from paralysis to a functional level after high-dose steroid treatment. We shortened the duration of diagnosis from 49 days to one day by adopting a diagnostic algorithm after experiencing the first case.

    Eosinophilic granulomatosis with polyangiitis (EGPA), previously called Churg-Strauss syndrome, frequently affects the peripheral nervous system. We conducted a multicenter, double-blind, three-arm treatment period, randomized, pre-post trial to assess the efficacy of intravenous immunoglobulin (IVIg) administration for residual peripheral neuropathy in patients with EGPA that is in remission, indicated by laboratory indices. Twenty-three patients were randomly assigned into three groups, in which the timing of IVIg and placebo administration was different. Each group received one course of intervention and two courses of placebo at 2-week intervals. Treatment effects were assessed every 2 weeks for 8 weeks. The primary outcome measure, the amount of change in the manual muscle testing sum score 2 weeks after IVIg administration, significantly increased (p = 0.002). The results over time suggested that this effect continued until the last assessment was done 8 weeks later. The number of muscles with manual muscle testing scores of three or less (p = 0.004) and the neuropathic pain scores represented by the visual analogue scale (p = 0.005) also improved significantly 2 weeks after IVIg administration. This study indicates that IVIg treatment for EGPA patients with residual peripheral neuropathy should be considered even when laboratory indices suggest remission of the disease.

    We report a 62-year-old man with mild fever, headache and acute visual loss in his right eye due to anterior ischaemic optic neuropathy (AION), followed a few days later by pain in the legs and left arm associated with numbness and weakness. Giant cell arteritis complicated by AION was suspected at the beginning and high-dose oral glucocorticoids were started. However, on the basis of the past medical history of nasal polyposis, asthma, and hypereosynophilia as well as of further investigations (biopsy of the nasal mucosa showing granulomatous inflammation with a rich eosinophilic infiltrate, electromyography demonstrating, mononeuritis multiplex and positive p-ANCA), eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss syndrome, was diagnosed. Because visual acuity in the right eye deteriorated despite glucocorticoid therapy, pulse intravenous cyclophosphamide was started, subsequently replaced by oral azathioprine, while prednisone was slowly tapered. This treatment led to gradual improvement of the neurological symptoms, whereas the right visual impairment remained unchanged. EGPA-related AION is an uncommon lesion that is probably due to vasculitic involvement of posterior ciliary and/or chorioretinal arteries. The prognosis of established AION is poor for the affected eye, even when glucocorticoid treatment is started immediately. However, early recognition of AION and prompt aggressive treatment with high-dose glucocorticoids plus cyclophosphamide can prevent visual loss in the unaffected eye.

    Renal transplantation is the optimal treatment for selected patients with end-stage renal disease (ESRD). However, the survival benefit of renal transplantation among patients with ESRD attributed to granulomatosis with polyangiitis (GPA) is unknown. We identified patients from the United States Renal Data System with ESRD due to GPA (ESRD-GPA) between 1995 and 2014. We restricted our analysis to waitlisted subjects to evaluate the impact of transplantation on mortality. We followed patients until death or the end of follow-up. We compared the relative risk (RR) of all-cause and cause-specific mortality in patients who received a transplant versus non-transplanted patients using a pooled logistic regression model with transplantation as a time-varying exposure. During the study period, 1525 patients were waitlisted and 946 received a renal transplant. Receiving a renal transplant was associated with a 70% reduction in the risk of all-cause mortality in multivariable-adjusted analyses (RR=0.30, 95% CI 0.25 to 0.37), largely attributed to a 90% reduction in the risk of death due to cardiovascular disease (CVD) (RR=0.10, 95% 0.06-0.16). Renal transplantation is associated with a significant decrease in all-cause mortality among patients with ESRD attributed to GPA, largely due to a decrease in the risk of death to CVD. Prompt referral for transplantation is critical to optimise outcomes for this patient population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To describe the efficacy and safety of omalizumab, an anti-IgE monoclonal antibody, in patients with refractory and/or relapsing eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA). We conducted a nationwide retrospective study including EGPA patients who received omalizumab. Response was defined as the absence of asthma and/or sinonasal exacerbations with a prednisone dosage of ≤7.5 mg/day (complete response) or >7.5 mg/day (partial response). Seventeen patients (median age 45 years) received omalizumab for severe steroid-dependent asthma (88%) and/or sinonasal involvement (18%). After a median follow-up of 22 months, 6 patients (35%) achieved a complete response, 5 patients (30%) achieved a partial response, and 6 patients (35%) had no improvement. The median Birmingham Vasculitis Activity Score decreased from 2.5 at baseline to 0.5 at 12 months. The median number of exacerbations per month decreased from 1 at baseline to 0 at 12 months, and the median forced expiratory volume in 1 second increased from 63% of the percent predicted at baseline to 85% of the percent predicted at 12 months. The median prednisone dosage decreased from 16 mg/day at baseline to 11 mg/day at 6 months and 9 mg/day at 12 months. Omalizumab was discontinued in 8 patients (47%) during follow-up, because of remission (12.5%), adverse event despite disease remission (12.5%), refractory disease (25%), or relapse (50%). Relapses included retrobulbar optic neuritis attributable to EGPA in 2 patients and severe asthma flare in 2 others. The results of this study suggest that omalizumab may have a corticosteroid-sparing effect in EGPA patients with asthmatic and/or sinonasal manifestations, but reducing the corticosteroid dose may also increase the risk of severe EGPA flares, which raises the question of the safety of omalizumab in patients with EGPA. © 2016, American College of Rheumatology.

    Full Text Available Introduction. Tuberculosis patients are rarely asymptomatic. Acute virus myocarditis presents with a wide range of symptoms, from mild dyspnea or chest pain to cardiogenic shock and death. Case Outline. A 26-year-old Caucasian man non-smoker presented with one-week history of lower extremities’ swelling. The patient’s medical history also revealed a two-day episode of subfebrile temperature with scanty hemoptysis three weeks prior to admission. The episode had not provoked him to seek medical care. Physical examination revealed generalized oedema, and laboratory analysis showed signs of acute renal insufficiency. Enlarged heart and hilar shadows, bilateral massive cavitary pulmonary opacities and pleural effusion were found at chest radiography. Sputum smears were Mycobacteria negative on direct microscopy. Electrocardiogram changes and echocardiography were suggestive of acute myocarditis with dilated cardiomyopathy. IgM titer to adenovirus was positive. Under diuretics, angiotensin-converting-enzyme inhibitor, beta-blocker, antibiotics and bed rest, fast heart compensation and renal function repair were achieved. Radiographic pulmonary changes promptly regressed except for a cavity in the right upper lobe. Bronchial aspirate from the affected lobe was Mycobacteria positive on direct microscopy and culture positive for Mycobacterium tuberculosis. Standard anti-tuberculosis drug regimen led to recovery. Conclusion. In the unusual common existence of two diseases whose presentation initially mimicked Wegener’s granulomatosis, acute dilated cardiomyopathy contributed to pulmonary tuberculosis detection. To prevent diagnostic delay in tuberculosis, further efforts in population education are necessary together with continual medical education.

    Full Text Available A granulomatose de Wegener (GW é uma vasculite granulomatosa multissistêmica rara, idiopática, que acomete vasos de pequeno e médio calibres, e que classicamente envolvem os tratos respiratórios superior, inferior e rins. Na forma limitada da doença, diversos sítios anatômicos podem ser afetados isoladamente. Foi descrito o caso de uma paciente jovem, que iniciou o acometimento da GW por dispnéia, estridor laríngeo e hipacusia. A investigação evidenciou o acometimento localizado na glote, e envolvimento da membrana timpânica comprovado por biópsia. A paciente obteve resposta com o tratamento instituído, mas permaneceu com seqüelas otológicas. Revisa-se neste artigo algumas das manifestações focais da GW, salientando especialmente as manifestações otológicas.Wegener's granulomatosis (WG is a rare, idiopathic granulomatous vasculitis, affecting small and medium-sized vessels, classically involving upper and lower respiratory tracts and kidneys. In the limited form of the disease, several other sites can be affected. We describe the case of a young woman who presented her disease with dyspnea, laryngeal stridor and hearing loss. Investigation revealed localized glottis involvement and a tympanum biopsy confirmed granulomatous vasculitis. The patient had a partial response with the treatment, with residual deafness. We performed a review concerning the focal manifestations of WG, focusing in the ear involvement.

    Given reports on the increased prevalence of thromboembolic incidents in patients with eosinophilic granulomatosis with polyangiitis (EGPA; Churg-Strauss syndrome), we investigated whether fibrin clot properties are unfavorably altered in EGPA. Ex vivo plasma fibrin clot characteristics, including clot permeability, turbidimetry and efficiency of fibrinolysis using two assays, were investigated in 34 consecutive patients with remission in EGPA according to the Birmingham Vasculitis Activity Score version 3 (23 female, 11 male), aged 48 (range, 21-80) years. The control group comprised 34 age- and sex- matched volunteers. Compared with controls, patients with EGPA were characterized by denser fiber clots (estimated pore size, Ks, 7.30±0.93 vs 10.14±1.07 10-9 cm2), faster fibrin polymerization (lag phase in a turbidimetric curve, 41.8±3.6 vs 47.4±2.9 s), thicker fibrin fibers (maximum absorbance, ΔAbs, 0.87±0.09 vs 0.72±0.07), higher maximum levels of D-dimer released from clots (DDmax 4.10±0.46 vs 3.54±0.35 mg/L), and prolonged clot lysis time (t50%; 9.50±1.45 vs 7.56±0.87 min); all p<0.0001. Scanning electron microscopy images confirmed denser plasma fibrin networks composed of thinner fibers formed in EGPA. Antineutrophil cytoplasmic antibody status and C-reactive protein did not affect clot variables. Multivariate analysis adjusted for fibrinogen showed that Ks was predicted by eosinophil count, peak thrombin generation, factor VIII, and soluble CD40 ligand, whereas eosinophil count, peak thrombin generation and antiplasmin predicted t50%. This study is the first to show that EGPA is associated with prothrombotic plasma fibrin clot phenotype, which may contribute to thromboembolic manifestations reported in this disease.

    This study aims to elucidate the prognosis and the effectiveness of current treatments for Japanese patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). Patients with newly diagnosed MPA and GPA were enrolled in a nationwide, prospective, inception cohort study from 22 tertiary Japanese institutions, and treatment patterns and responses were evaluated for 24 months. Primary outcome measures were rates of remission (Birmingham Vasculitis Activity Score, 0) and remission with low-dose glucocorticoids (GC) (prednisolone ≤ 10 mg) (GC remission). Of 156 enrolled patients, 78 MPA patients and 33 GPA patients were included. Concomitant cyclophosphamide (CY) was used in 24 MPA (31 %) and 20 GPA (60 %) patients during the initial 3 weeks of treatment. After 6 months, remission was achieved in 66 MPA (85 %) and 29 GPA (87 %) patients, while GC remission was obtained in only 31 MPA (40 %) and 13 GPA (39 %) patients. During the 24-month period, 14 MPA patients and 2 GPA patients died; end stage renal disease (ESRD) was noted in 13 MPA patients but no GPA patients. Patients with severe disease, according to the European Vasculitis Study Group (EUVAS) classification, showed poorer ESRD-free and overall survival rates than those with generalized disease (p < 0.0001). There were no differences in relapse-free survival rates between GPA and MPA, among EUVAS-defined disease severity categories, and between anti-neutrophil cytoplasmic antibody subspecialties. The majority of Japanese patients with MPA and GPA received treatment with high-dose GC and limited CY use, and showed high remission and relapse-free survival rates but low GC remission rates in clinical practice.

    Full Text Available Ninad Parekh, Edward Epstein, Suzanne El-Sayegh Department of Medicine, Division of Nephrology, Staten Island University Hospital, Staten Island, NY, USA Introduction: Diagnosing the etiology of a rapidly progressive glomerulonephritis is of vital importance to guide appropriate therapeutic management. This case highlights the complexity involved in establishing diagnosis when presentation is atypical. In certain cases diagnosis cannot be established based on clinical presentation or biopsy findings alone, and critical analysis of biopsy findings in context of clinical presentation is crucial to guide the clinical decision-making process.Case presentation: A 47-year-old Hispanic male with history of granulomatosis with polyangiitis (GPA in remission on azathioprine, presented with fatigue and lethargy. Physical examination was unremarkable. Laboratory data revealed elevated creatinine and otherwise normal electrolytes. Urinalysis showed numerous dysmorphic red blood cells with few red cell casts. His serologic results were all negative except anti-proteinase-3 antibody at very low titers. Kidney biopsy showed necrotizing crescentic glomerulonephritis with linear immunoglobulin G staining along the basement membrane.Conclusion: This case presented conflicting serologic and histopathologic findings. The presence of anti-proteinase-3 antibody supported diagnosis of recurrence of GPA. However, linear staining of immunoglobulin G (IgG on immunofluorescence (IF staining of renal biopsy supported anti-glomerular basement membrane (GBM disease. The treatment of anti-GBM disease and GPA both involve immunosuppression with prednisone and cyclophosphamide. However, patients with anti-GBM disease are also treated with plasmapheresis early in the disease presentation to prevent further damage. The patient with GPA, on the other hand, was shown to benefit from plasmapheresis only in the case of severe renal disease (serum creatinine level more than 5 mg/dL or

    To guide nosology and classification of patients with eosinophilic granulomatosis with polyangiitis (EGPA) based on phenotype and presence or absence of ANCA. Organ manifestations and ANCA status were retrospectively analyzed based on the presence or not of predefined definite vasculitis features or surrogates of vasculitis in patients asthma, eosinophilia, and at least one systemic organ manifestation attributable to systemic disease. The study population included 157 patients (mean age 49.4±14.1), with a follow-up of 7.4±6.4years. Patients with ANCA (31%) more frequently had weight loss, myalgias, arthralgias, biopsy-proven vasculitis, glomerulonephritis on biopsy, hematuria, leukocytoclastic capillaritis and/or eosinophilic infiltration of arterial wall on biopsy, and other renal disease. A total of 41% of patients had definite vasculitis manifestations (37%) or strong surrogates of vasculitis (4%), of whom only 53% had ANCA. Mononeuritis multiplex was associated with systemic vasculitis (p=0.005) and with the presence of ANCA (p<0.001). Overall, 59% of patients had polyangiitis as defined by definite vasculitis, strong surrogate of vasculitis, mononeuritis multiplex, and/or ANCA with at least one systemic manifestation other than ENT or respiratory. Patients with polyangiitis had more systemic manifestations including arthralgias (p=0.02) and renal disease (p=0.024), had higher peripheral eosinophilia (p=0.027), and a trend towards less myocarditis (p=0.057). Using predefined criteria of vasculitis and surrogates of vasculitis, ANCA alone were found to be insufficient to categorise patients with vasculitis features. We suggest a revised nomenclature and definition for EGPA and a new proposed entity referred to as hypereosinophilic asthma with systemic (non vasculitic) manifestations.

    Full Text Available Peritoneal keratin granulomatosis is a rare condition included under granulomatous lesions of the peritoneum. It can be secondary to neoplasms of the female genital tract and can mimic carcinomatosis intraoperatively. A case of a 40-year-old woman with a history of polycystic ovaries and a chief complaint of vaginal bleeding is presented. She was diagnosed with endometrioid adenocarcinoma with squamous differentiation in endometrial curettings. Intraoperatively, many peritoneal nodules were found, interpreted as peritoneal carcinomatosis. The woman underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, bilateral pelvic lymphadenectomy, and appendicectomy. Multiple biopsies were taken, as well as peritoneal washings. Microscopic examination revealed multiple keratin granulomas on the serosal surface of the ovaries, fallopian tubes, appendix, and omentum. Lymph node metastasis was not found. Peritoneal keratin granulomas (PKGs have been reported in cases of endometrioid adenocarcinoma with squamous differentiation of the uterine corpus, ovary, and atypical adenomyoma. It should be noted that the prognosis of cases of peritoneal keratin granulomas without viable tumor cells is favourable and that the histologic examination is essential for its diagnosis. We report a case of PKG in a patient with endometrial carcinoma with squamous differentiation, being the first in a woman with polycystic ovaries.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is a necrotizing vasculitis that predominantly affects small- to medium-sized vessels. It is characterized by a wide spectrum of extrapulmonary symptoms, including sinonasal and paranasal sinus abnormalities. These are the most common features of this disease, constituting diagnostic criteria for EGPA. However, the actual clinical features, cellular mechanisms and impact on patients' quality of life (QoL) are still a matter of study. Thirty-nine EGPA patients underwent multidimensional rhinological evaluations, including rhinofibroscopy, nasal cytology, and QoL questionnaires. This was coupled with respiratory and rheumatological assessments. Twenty-eight patients were diagnosed with chronic rhinosinusitis (CRS). Of these, 18 had nasal polyposis (NP). Chronic rhinitis was diagnosed in 10 patients. Of these, 3 had allergic rhinitis (AR) and seven had non-AR (NAR). Overall, only 1 patient (2.6%) was normal. Nasal cytology showed that hypereosinophilia was present in 17/28 patients with CRS, 4/7 patients with NAR and all patients with AR. SNOT-22 and SF-36 showed a severe impact of nasal symptoms on QoL. No differences in asthma control or rheumatological patterns for EGPA were observed among patients with or without NP. Even when the rheumatological assessment scored EGPA "under control" according to the Birmingham Vasculitis Activity Score and Vasculitis Damage Index, sinonasal diseases and related nasal inflammatory processes were not controlled. Therefore, there is a need for clinical monitoring and targeted treatment to control the inflammatory processes and improve the QoL of EGPA patients. © 2018 S. Karger AG, Basel.

    Occupational lung diseases are caused by several toxic substances including heavy metals; however, the exact pathologic mechanisms remain unknown. In the workplace, dental technicians are often exposed to heavy metals such as cobalt, nickel, or beryllium and occasionally develop occupational lung diseases. We described a case of occupational lung disease in a patient who was employed as a dental technician for over a decade. A 31-year-old, non-smoking woman presented with productive cough and shortness of breath of several weeks duration. Chest computed tomography revealed a large number of scattered, bilateral small pulmonary nodules throughout the lung field, and multiple mediastinal lymph nodes enlargement. Percutaneous needle biopsy showed multifocal small granulomas with foreign body type giant cells suggestive of heavy metals inhalation. The patient's condition improved on simple avoidance strategy for several months. This case highlighted the importance of proper workplace safety.

    Ascariasis is one of the most prevalent and widespread human helminthic infections, especially in children of the underdeveloped countries. It is related to conditions of poverty, malnutrition and poor hygiene. According to the complex life cycle of the parasite, several and different intestinal and extraintestinal complications can arise, including peritonitis. Appropriate treatment and preventive measures are very important factors to avoid deaths caused by this disease.

    We report the case of a 3 year-old girl, coming from a rural area of Colombia, who presented peritonitis by Ascaris lumbricoides, preceded by persistent diarrhea, pain and abdominal mass. She was incidentally diagnosed by means of laparotomy and peritoneal biopsy, because an intestinal lymphoma was suspected.

    La ascariasis es una parasitosis ampliamente diseminada en el mundo, especialmente en los niños de los países en vías de desarrollo, ligada a condiciones de pobreza, desnutrición y mala higiene. Se acepta que es la geohelmintiasis más frecuente entre todas las parasitosis humanas. Dado el complejo ciclo de vida del parásito causal, se pueden producir muchas y variadas complicaciones intestinales y extraintestinales, entre ellas la peritonitis. El tratamiento oportuno y las medidas preventivas son factores importantísimos para evitar las muertes por esta enfermedad.

    Se presenta el caso de una niña de 3 años de edad, procedente de una zona rural colombiana quien presentó una peritonitis por áscaris, manifestada por diarrea persistente, dolor y masa abdominal, en quien se hizo el diagnóstico en forma casual mediante laparotomía y biopsia peritoneal, ante la sospecha de un linfoma.

    There is evidence that the leptin/ghrelin system is involved in T-cell regulation and plays a role in (auto)immune disorders such as SLE, RA and ANCA-associated vasculitides (AAVs). Here, we evaluate the genetic background of this system in WG. We screened variations in the genes encoding leptin, ghrelin and their receptors, the leptin receptor (LEPR) and the growth hormone secretagogue receptor (GHSR). Three single nucleotide polymorphisms (SNPs) in each gene region were analysed in 460 German WG cases and 878 ethnically matched healthy controls. A three-SNP haplotype of GHSR was significantly associated with WG [P = 0.0067; corrected P-value (P(c)) = 0.026; odds ratio (OR) = 1.30; 95% CI 1.08, 1.57], as was one non-synonymous SNP in LEPR (Lys656Asn, P = 0.0034; P(c) = 0.013; OR = 0.72; 95% CI 0.58, 0.90). These four SNPs were re-analysed in independent cohorts of 226 German WG cases and 519 controls. While the GHSR association was not confirmed, allele frequencies of the LEPR SNP were virtually identical to those from the initial cohorts. Analysis of this SNP in the combined WG and control panels revealed a significant association of the LEPR 656Lys allele with WG (P = 0.00032; P(c) = 0.0013; OR = 0.72; 95% CI 0.60, 0.86). Remarkably, the Lys656Asn SNP showed contrasting allele distribution in two cohorts of 108 and 88 German cases diagnosed with Churg-Strauss syndrome (CSS, combined P = 0.0067; OR = 1.41; 95% CI 1.10, 1.81), whereas identical allele frequencies were revealed when comparing British WG and microscopic polyangiitis cases. While GHSR has to be further evaluated, these data provide profound evidence for an association of the LEPR Lys656Asn SNP with AAV, resulting in opposing effects in WG and CSS.

    Full Text Available A vasculite necrosante foi descrita em 1866 e seu espectro é muito amplo, uma vez que acomete vasos arteriais e venosos de todos os calibres e de vários órgãos, apresenta diversos tipos de infiltrados inflamatórios, tem um significante número de manifestações clínicas e pode ter ou não fatores desencadeantes identificáveis. A sempre controversa classificação das vasculites mudou radicalmente com a descoberta dos anticorpos anticitoplasma de neutrófilos em 1982, contemplando atualmente a doença de Goodpasture, as vasculites associadas aos anticorpos anticitoplasma de neutrófilos, as vasculites por imunocomplexos e outros tipos de vasculites. As evidências de que os anticorpos anticitoplasma de neutrófilos estão envolvidos na patogênese destas lesões trouxeram avanços consideráveis para o seu diagnóstico e tratamento. Granulomatose de Wegener, doença de Churg-Strauss e poliangeíte microscópica, todas vasculites associadas aos anticorpos anticitoplasma de neutrófilos, são as vasculites sistêmicas que mais acometem os pulmões. Suas manifestações clínicas comuns são tosse, hemorragia alveolar difusa ou asma de difícil controle. Na arterite de Takayasu, na doença de Behçet, na púrpura de Henoch-Schönlein e nas vasculites associadas às doenças do colágeno o acometimento pulmonar é mais raro. Em todos os casos há evidências de serem processos de origem imunológica e com base neste princípio são propostas as abordagens terapêuticas.Necrotizing vasculitis was first described in 1866.

Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomatous lung diseases. Differential diagnosis is challenging, and includes both infectious (mycobacteria and fungi and noninfectious lung diseases (sarcoidosis, necrotising sarcoid granulomatosis, hypersensitivity pneumonitis, hot tub lung, berylliosis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, rheumatoid nodules, talc granulomatosis, Langerhans cell histiocytosis and bronchocentric granulomatosis. Bronchoalveolar lavage, endobronchial ultrasound-guided transbronchial needle aspiration, transbronchial cryobiopsy, positron emission tomography and genetic evaluation are potential candidates to improve the diagnostic accuracy for granulomatous lung diseases. As granuloma alone is a nonspecific histopathological finding, the multidisciplinary approach is important for a confident diagnosis.

  1. Anti-neutrophil cytoplasmic antibodies in rheumatoid arthritis: two case reports and review of literature

    2012-12-01

    Full Text Available Abstract Background Anti-neutrophil cytoplasmic antibodies are typically detected in anti-neutrophil cytoplasmic antibody associated vasculitis, but are also present in a number of chronic inflammatory non-vasculitic conditions like rheumatoid arthritis. Rare cases of granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis, a vasculitic disorder frequently associated with the presence of anti-neutrophil cytoplasmic antibodies in patients with rheumatoid arthritis have been described in literature. Case presentation We report two middle-aged female patients with rheumatoid arthritis who developed anti-neutrophil cytoplasmic antibodies and symptoms reminiscent of granulomatosis with polyangiitis. Despite the lack of antibodies specific for proteinase 3 and the absence of a classical histology, we report a probable case of granulomatosis with polyangiitis in the first patient, and consider rheumatoid vasculitis in the second patient. Conclusion Taken together with previous reports, these cases highlight that anti-neutrophil cytoplasmic antibodies have to be evaluated very carefully in patients with rheumatoid arthritis. In this context, anti-neutrophil cytoplasmic antibodies detected by indirect immunofluorescence appear to have a low diagnostic value for granulomatosis with polyangiitis. Instead they may have prognostic value for assessing the course of rheumatoid arthritis.

    Antineutrophil cytoplasmatic antibodies (ANCA)-associated vasculitides (Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome) show quite variable courses. Clinical features of the full blown generalized systemic vasculitis are usually found in the respiratory tract and the kidney. Pulmonary involvement of Wegener's granulomatosis shows commonly nodules and cavitations but also diffuse alveolar hemorrhage. We report the case of a 57 year-old man suffering from dyspnea, thoracal pain, arthralgia, purpura, scleritis and tinitus. Specimen of the kidney showed segmental glomerulosclerosis and tubulointerstitial nephritis. Because of the presence of cANCA Wegener's disease was assumed. Pulmonary infiltrates developed under immunosuppressive treatment with cyclophosphamid. As differential diagnosis of the pulmonary infiltrates, we considered invasive pulmonary aspergillosis as well as infiltrates due to Wegener's granulomatosis. In spite of maximal therapeutic management of patient died of respiratory and cardiovascular failure. The findings at autopsy showed distinct invasive pulmonary aspergillosis and perifocal hemorrhage.

    Pulmonary lymphoproliferative disorders include plasma cell granuloma, Castleman's disease, pseudolymphoma, lymphocytic interstitial pneumonia, angioimmunoblastic lymphadenopathy and lymphomatoid granulomatosis. We carried out a retrospective study for the purpose of analysing the clinical and radiological findings of 16 cases of pulmonary lymphoproliferative disorders seen during the decade 1980-1990. The cases comprised 8 lymphocytic interstitial pneumonia, 5 lymphomatoid granulomatosis, 2 plasma cell granuloma and 1 angioimmunoblastic lymphadenopathy. Owing to the overlap and low specificity of the radiological patterns in these processes, histopathological examination is required. In view of the frequent evolution of pulmonary lymphoproliferative disorders to malignant lymphoma (4 cases, 1 of lymphocytic interstitial pneumonia and 3 of lymphomatoid granulomatosis, in our series) we provide a description of the radiological changes that occur during this process.

Os resultados observados e os dados da literatura nos permitiram concluir que enquanto na meningoencefalite necrosante focal por Toxoplasma gondii o acometimento dos núcleos da base é freqüente, na meningoencefalite necrosante focal causada pelo Trypanosoma cruzi, lesões dessas estruturas parecem não ocorrer ou ser excepcionais. De outro lado, o acometimento da substância branca parece nitidamente maior na meningoencefalite chagásica que na meningoencefalite toxoplásmica, ao passo que o parasitismo e a hemorragia do tecido nervoso, bem como as lesões das bainhas de mielina são mais freqüentes e intensos na meningoencefalite causada pelo Trypanosoma cruzi que naquela por Toxoplasma.Twenty-two HIV+ patients with encephalitis were studied. Of these, 7 had meningoencephalitis due to Toxoplasma gondii (MT and 15 due to Trypanosoma cruzi (MC. Pathologic and computerized axial tomography (CAT changes were compared. We found that focal necrotizing encephalitis due to Toxoplasma involved the cerebral cortex and the basal ganglia, whereas lesions due to Trypanosoma cruzi were centered in the white matter, sometimes extending into the cortex. Hemorrhages, myelin lesions and organisms were more pronounced in chagasic than in toxoplasmic encephalitis. These findings are consistent with the literature reviewed.

  6. Necrose pancreática delimitada e outros conceitos atuais na avaliação radiológica da pancreatite aguda

    Directory of Open Access Journals (Sweden)

    Elen Freitas de Cerqueira Cunha

    2014-06-01

    Full Text Available A pancreatite aguda é uma condição inflamatória causada por ativação intracelular e extravasamento inapropriado de enzimas proteolíticas que determinam destruição do parênquima pancreático e dos tecidos peripancreáticos. Consiste em uma condição clínica bastante frequente, identificando-se duas formas principais de apresentação: a forma edematosa, menos intensa, e a forma necrosante, a forma grave da doença que acomete uma proporção significativa dos pacientes. A avaliação radiológica, sobretudo por tomografia computadorizada, tem papel fundamental na definição da conduta nos casos graves, sobretudo no que diz respeito à caracterização das complicações locais, que têm implicação prognóstica, e na determinação do tipo de abordagem terapêutica. Novos conceitos incluem a subdivisão da pancreatite necrosante nas formas de necrose do parênquima pancreático concomitante com necrose dos tecidos peripancreáticos ou necrose restrita aos tecidos peripancreáticos. Além disso, houve sistematização dos termos: acúmulos líquidos agudos peripancreáticos, pseudocisto, alterações pós-necróticas pancreáticas/peripancreáticas e necrose pancreática delimitada. Tal conhecimento é de extrema relevância no sentido de uniformizar a linguagem entre os especialistas envolvidos no diagnóstico e tratamento desses pacientes.

    Full Text Available O objetivo do presente artigo é revisar a literatura acerca dos conhecimentos atuais relativos à terapia nutricional - enteral e parenteral - para os recém-nascidos pré-termo, principalmente os de muito baixo peso, destacando seu efeito protetor na sepse neonatal e na enterocolite necrosante. As diferentes modalidades de alimentação do recém-nascido prematuro - especialmente para aqueles de muito baixo peso - e seu efeito protetor na diminuição de complicações (mormente as infecciosas foram analisadas. A utilização preferencial do leite materno na nutrição enteral, o controle das ofertas energético-protéicas, o início precoce da nutrição enteral mínima, a introdução precoce da alimentação parenteral - nas primeiras 24 horas - e a utilização dos imunonutrientes que tenham estudos suficientes para fundamentar sua indicação podem se constituir em boas diretrizes adjuvantes na prevenção da sepse neonatal e da enterocolite necrosante. Sem embargo, percebe-se a necessidade de mais estudos - preferencialmente multicêntricos, controlados e randomizados - para esclarecer o papel protetor da nutrição no RNPT, não somente na prevenção de infecções, mas também para auxiliar o desenvolvimento neural e a prevenção de consequências deletérias futuras.

    Langlois, V; Marie, I

    2017-07-01

    Antineutrophil cytoplasmic antibodies (ANCA) associated with infective endocarditis are a rare disorder. The condition can mimic primary systemic vasculitis (i.e. granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). Thus, a wrong diagnosis of valvular involvement related to primary systemic vasculitis can be made in patients exhibiting ANCA associated with infective endocarditis. Because treatment of both conditions is different, this wrong diagnosis will lead to dramatic consequences in these latter patients. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of ANCA associated with infective endocarditis.

    BACKGROUND Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis is a severe condition encompassing two major syndromes: granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis) and microscopic polyangiitis. Its cause is unknown, and there is debate about whether it is a single disease entity and what role ANCA plays in its pathogenesis. We investigated its genetic basis. METHODS A genomewide association study was performed in a discovery cohort of 1233 U.K. patients with ANCA-associated vasculitis and 5884 controls and was replicated in 1454 Northern European case patients and 1666 controls. Quality control, population stratification, and statistical analyses were performed according to standard criteria. RESULTS We found both major-histocompatibility-complex (MHC) and non-MHC associations with ANCA-associated vasculitis and also that granulomatosis with polyangiitis and microscopic polyangiitis were genetically distinct. The strongest genetic associations were with the antigenic specificity of ANCA, not with the clinical syndrome. Anti–proteinase 3 ANCA was associated with HLA-DP and the genes encoding α1-antitrypsin (SERPINA1) and proteinase 3 (PRTN3) (P = 6.2×10−89, P = 5.6×10−12, and P = 2.6×10−7, respectively). Anti–myeloperoxidase ANCA was associated with HLA-DQ (P = 2.1×10−8). CONCLUSIONS This study confirms that the pathogenesis of ANCA-associated vasculitis has a genetic component, shows genetic distinctions between granulomatosis with polyangiitis and microscopic polyangiitis that are associated with ANCA specificity, and suggests that the response against the autoantigen proteinase 3 is a central pathogenic feature of proteinase 3 ANCA–associated vasculitis. These data provide preliminary support for the concept that proteinase 3 ANCA–associated vasculitis and myeloperoxidase ANCA–associated vasculitis are distinct autoimmune syndromes.

    Four cases of the lethal midline granuloma or malignant granuloma of the nose were treated by irradiation and chemotherapy, which are generally prescribed for malignant lymphomas. Clinical, histological and laboratory examination indicated that they were the lethal midline granuloma and clearly differentiated from Wegener's granulomatosis or malignant lymphoma. All of the cases exhibited primary remission. The four cases were observed up to 38, 22, 14, and 10 months since the beginning of the therapy, showing no local or general recurrence. (author)

    The radiological and scintigraphic results of 52 patients suffering from granulomatosis and pericarditis, the latter as a consequence of radiotherapy in 30 cases, were compared. The radiological examination after application of an artificial pneumopericardium allows the interpretation of both the quantity of the exudate and the condition of epicardium and pericardium. Applying additional scintigraphic methods central hemodynamic parameter can be examined; thus in exsudative pericarditis s decrease of the cardiac output and of the cardiac index could be stated intensifying with increasing exsudation.

  5. A pragmatic approach to vasculitis in the gastrointestinal tract.

    2017-06-01

    Although vasculitis involving the gastrointestinal tract (GIT) is an uncommon occurrence, occasionally vasculitis can present as haemorrhagic infarction or ischaemia for which a length of bowel is removed. Invariably, the appropriate clinical history is not forthcoming, or vasculitis is not clinically suspected. The purpose of this overview is to provide the practising gastrointestinal (GI) pathologist with a framework to recognise and diagnose vasculitides within the GIT. The classification may be approached by aetiological agent or size of vessel involved; an international consensus group now favours the latter approach. The symptoms that systemic and/or localised vasculitis may cause in the GIT are protean and non-specific. As a result, pathologists examining resection specimens for unexplained haemorrhagic infarction or ischaemia should be aware that vasculitis may be a potential cause. Several well-known systemic vasculitides such as polyarteritis nodosa, microscopic polyangiitis, eosinophilic granulomatosis with polyangiitis or Churg-Strauss syndrome and granulomatosis with polyangiitis or Wegener's granulomatosis can occur in the GIT. The latter three constitute the antineutrophil cytoplasmic antibody-positive vasculitides. In addition, the so-called solitary organ vasculitis (SOV) can occur in the GIT as the harbinger of later onset systemic vasculitis, and be the cause of the GIT symptoms. In addition, SOV can occur incidentally and coexist with GIT disease such as gallstones or polyps, and there may be no manifestations of systemic vasculitis for years, or not at all.

  6. Insights into the pathogenesis and clinicopathological spectrum of oral vegetable granuloma. Case series with literature review

    Directory of Open Access Journals (Sweden)

    Shankargouda Patil

    2017-10-01

    Full Text Available Oral vegetable granuloma represents an inflammatory lesion of foreign body origin resulting from the implantation of vegetable matter. Controversy regarding its pathogenesis is reflected by the various terminologies used to describe the lesion. Its diverse clinical presentations are due to variations in the antigenic potential of the vegetable material and the host response. As the diagnosis is solely histopathological, it is critical to differentiate vegetable granuloma from other oral granulomatous lesions like tuberculosis, sarcoidosis and Wegner’s granulomatosis. Here, we report six cases with the varied clinicopathological presentation of hyaline ring granulomas in association with different pathological lesions.

    Vasculitis is defined as an inflammatory process involving blood vessels, and can lead to destruction of the vascular wall and ischemic damage to the organs supplied by these vessels. The lung is commonly affected. A number of attempts have been made to classify and organize pulmonary vasculitis, but because the clinical manifestations and pathologic features of the condition overlap considerably, these afforts have failed to achieve a consensus. We classified pulmonary vasculitis as belonging to either the angitiis-granulomatosis group, the diffuse pulmonary hemorrhage with capillaritis group, or 'other'. Characteristic radiographic and CT findings of the different types of pulmonary vasculitis are illustrated, with a brief discussion of the respective disease entities

    The diagnosis and management of Wegener's granulomatosis and microscopic polyarteritis are complicated by the lack of specific diagnostic tests. The diagnostic performance of a solid-phase radioimmunoassay, which detects the autoantibodies against neutrophil cytoplasm present in these disorders, was assessed in a prospective study of patients with suspected vasculitis and/or rapidly progressive nephritis. The assay had a sensitivity and specificity of 96% when carried out in combination with a specific inhibition stage and indirect immunofluorescence staining of alcohol-fixed normal neutrophils.

This syndrome is considered after ruling out other differential diagnoses. A-38-year old man presented with acute renal failure and uveitis. The histologic findings of renal biopsy showed acute tubulointestitioal nephritis. The patient had no clinical and paraclinical manifestations of other etiologies of interstitial nephritis and uveitis such as Wegener's granulomatosis , Sjogren's syndrome or sarcoidosis. The diagnosis of TINU-Syndrome was therefore considered. The patient was treated by oral and ophthalmic prednisolone and had a good response to treatment.

    Polyglandular autoimmune syndrome (PGA) and eosinophilic granulomatosis with polyangiitis (EGPA) do not seem to represent a coincidental association. A case of a 15-year-old boy is reported who presented with severe systemic inflammation, perimyocarditis and cardiogenic shock, in whom EGPA was initially suspected and later diagnosed with autoimmune adrenalitis with PGA. The severity of the systemic inflammation and perimyocarditis suggests a more widespread autoimmune-mediated process. Autoimmune adrenal insufficiency should be considered in all cases of pericarditis and perimyocarditis, especially when the severity of clinical manifestations exceeds the expected for the severity of the cardiac findings, as timely identification and prompt treatment may be life-saving.

    We herein describe two cases of refractory antineutrophil cytoplasmic antibody-associated vasculitis (AAV) complicated with diabetes insipidus (DI) possibly related to hypertrophic pachymeningitis (HP). One patient had microscopic polyangiitis and HP, which were refractory to cyclophosphamide, azathioprine, rituximab, mycophenolate mofetil (MMF), and mizoribine. Remission was finally achieved with the use of etanercept, but DI occurred 5 years later. The other patient had granulomatosis with polyangiitis, which that was refractory to cyclophosphamide, methotrexate, MMF, and rituximab. DI subsequently developed, but was successfully treated with etanercept. Dura mater hypertrophy was macroscopically observed in the latter case.

    The aim of this pictorial essay was to present the main computed tomography findings seen in diffuse diseases of the trachea. The diseases studied included amyloidosis, tracheobronchopathia osteochondroplastica, tracheobronchomegaly, laryngotracheobronchial papillomatosis, lymphoma, neurofibromatosis, relapsing polychondritis, Wegener's granulomatosis, tuberculosis, paracoccidioidomycosis, and tracheobronchomalacia. The most common computed tomography finding was thickening of the walls of the trachea, with or without nodules, parietal calcifications, or involvement of the posterior wall. Although computed tomography allows the detection and characterization of diseases of the central airways, and the correlation with clinical data reduces the diagnostic possibilities, bronchoscopy with biopsy remains the most useful procedure for the diagnosis of diffuse lesions of the trachea.

    We report the case of a 74-year-old female who developed a necrotizing sclerokeratitis affecting her left eye after uncomplicated cataract surgery. She had no previous history of systemic autoimmune disease. Histopathology of the lesion revealed necrotic granulomatosis with an increased number of plasma cells. Surgically induced necrotizing sclerokeratitis (SINS) is a serious entity which requires prompt and aggressive therapy to prevent its potential devastating ocular consequences. Conjunctival resection and amniotic membrane grafting may be necessary to temporarily interrupt local immunologic events in severe cases. However, associated systemic immunomodulatory therapy seems to be mandatory (Arch Soc Esp Oftalmol 2009; 84: 577-580).

    Churg-Strauss syndrome (CSS) is a granulomatous small vessel vasculitis. It is characterized by asthma, allergic granulomatosis and vasculitis. This syndrome is rare in children. A 5 years old boy was admitted with cough, fever and dyspnea for 2 weeks. On the basis of laboratory data (peripheral eosinophilia), associated with skin biopsy, and history of CSS in his sister, this disease was eventually diagnosed. The patient had good response to corticosteroid. In every asthmatic patient with prolonged fever, eosinophilia and multisystemic involvment, CSS should be considered.

    Full Text Available Granulomatous disorders comprise a large family sharing the common histological denominator of granuloma formation. Collagenolytic or necrobiotic granuloma is one in which a granulomatous infiltrate develops around a central area of altered collagen and elastic fibers. The altered fibers exhibit new staining patterns, becoming either more basophilic which gives blue appearance (“blue granuloma” or eosinophilic giving red appearance (“red granuloma”. Conditions which exhibit blue granuloma include granuloma annulare, Wegener's granulomatosis, and rheumatoid vasculitis, whereas red granulomas include necrobiosis lipoidica, necrobiosis xanthogranuloma, rheumatoid nodules, Churg-Strauss syndrome, and eosinophilic cellulitis (Well's syndrome.

    Aim Currently, several different instruments are used to measure disease activity and extent in clinical trials of anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, leading to division among investigative groups and difficulty comparing study results. An exercise comparing six different vasculitis instruments was performed. Methods A total of 10 experienced vasculitis investigators from 5 countries scored 20 cases in the literature of Wegener granulomatosis or microscopic polyangiitis using 6 disease assessment tools: the Birmingham Vasculitis Activity Score (BVAS), The BVAS for Wegener granulomatosis (BVAS/WG), BVAS 2003, a Physician Global Assessment (PGA), the Disease Extent Index (DEI) and the Five Factor Score (FFS). Five cases were rescored by all raters. Results Reliability of the measures was extremely high (intraclass correlations for the six measures all=0.98). Within each instrument, there were no significant differences or outliers among the scores from the 10 investigators. Test/retest reliability was high for each measure: range=0.77 to 0.95. The scores of the five acute activity measures correlated extremely well with one another. Conclusions Currently available tools for measuring disease extent and activity in ANCA-associated vasculitis are highly correlated and reliable. These results provide investigators with confidence to compare different clinical trial data and helps form common ground as international research groups develop new, improved and universally accepted vasculitis disease assessment instruments.

    Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis), some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine). Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium), it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6):963-967.

    Several systemic diseases, including granulomatous and infectious processes, tumors, bone disorders, collagen-vascular and other autoimmune diseases may involve the middle ear and temporal bone. These diseases are difficult to diagnose when symptoms mimic acute otomastoiditis. The present report describes our experience with three such cases initially misdiagnosed. Their predominating symptoms were otological with mastoiditis, hearing loss, and subsequently facial nerve palsy. The cases were considered an emergency and the patients underwent tympanomastoidectomy, under the suspicion of otitis media with cholesteatoma, in order to remove a possible abscess and to decompress the facial nerve. The common features were the presence of severe granulation tissue filling the mastoid cavity and middle ear during surgery, without cholesteatoma. The definitive diagnoses was made by means of biopsy of the granulation tissue from the middle ear, revealing granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis) in one case, middle ear tuberculosis and diffuse large B-cell lymphoma respectively. After specific associated therapy facial nerve functions improved, and atypical inflammatory states of the ear resolved. As a group, systemic diseases of the middle ear and temporal bone are uncommon, but aggressive lesions. After analyzing these cases and reviewing the literature, we would like to stress upon the importance of microscopic examination of the affected tissue, required for an accurate diagnosis and effective treatment.

  13. The Role of the Immune Response in the Pathogenesis of Thyroid Eye Disease: A Reassessment.

    James T Rosenbaum

    Full Text Available Although thyroid eye disease is a common complication of Graves' disease, the pathogenesis of the orbital disease is poorly understood. Most authorities implicate the immune response as an important causal factor. We sought to clarify pathogenesis by using gene expression microarray.An international consortium of ocular pathologists and orbital surgeons contributed formalin fixed orbital biopsies. RNA was extracted from orbital tissue from 20 healthy controls, 25 patients with thyroid eye disease (TED, 25 patients with nonspecific orbital inflammation (NSOI, 7 patients with sarcoidosis and 6 patients with granulomatosis with polyangiitis (GPA. Tissue was divided into a discovery set and a validation set. Gene expression was quantified using Affymetrix U133 Plus 2.0 microarrays which include 54,000 probe sets.Principal component analysis showed that gene expression from tissue from patients with TED more closely resembled gene expression from healthy control tissue in comparison to gene expression characteristic of sarcoidosis, NSOI, or granulomatosis with polyangiitis. Unsupervised cluster dendrograms further indicated the similarity between TED and healthy controls. Heat maps based on gene expression for cytokines, chemokines, or their receptors showed that these inflammatory markers were associated with NSOI, sarcoidosis, or GPA much more frequently than with TED.This is the first study to compare gene expression in TED to gene expression associated with other causes of exophthalmos. The juxtaposition shows that inflammatory markers are far less characteristic of TED relative to other orbital inflammatory diseases.

  14. Anti-proteinase 3 anti-neutrophil cytoplasm autoantibodies recapitulate systemic vasculitis in mice with a humanized immune system.

    Mark A Little

    Full Text Available Evidence is lacking for direct pathogenicity of human anti-proteinase-3 (PR3 antibodies in development of systemic vasculitis and granulomatosis with polyangiitis (GPA, Wegener's granulomatosis. Progress in study of these antibodies in rodents has been hampered by lack of PR3 expression on murine neutrophils, and by different Fc-receptor affinities for IgG across species. Therefore, we tested whether human anti-PR3 antibodies can induce acute vasculitis in mice with a human immune system. Chimeric mice were generated by injecting human haematopoietic stem cells into irradiated NOD-scid-IL2Rγ⁻/⁻ mice. Matched chimera mice were treated with human IgG from patients with: anti-PR3 positive renal and lung vasculitis; patients with non-vasculitic renal disease; or healthy controls. Six-days later, 39% of anti-PR3 treated mice had haematuria, compared with none of controls. There was punctate bleeding on the surface of lungs of anti-PR3 treated animals, with histological evidence of vasculitis and haemorrhage. Anti-PR3 treated mice had mild pauci-immune proliferative glomerulonephritis, with infiltration of human and mouse leukocytes. In 3 mice (17% more severe glomerular injury was present. There were no glomerular changes in controls. Human IgG from patients with anti-PR3 autoantibodies is therefore pathogenic. This model of anti-PR3 antibody-mediated vasculitis may be useful in dissecting mechanisms of microvascular injury.

    Full Text Available Objective: to study the incidence rates of angina, myocardial infarction (MI, stroke, and the frequency of endovascular interventions in patients with systemic vasculitides, and the incidence rate of atherosclerosis according to autopsy data. Subjects and methods. Three hundred and twenty-one patients with systemic vasculitides: Wegener's granulomatosis (n = 138, Takayasu's arteritis (n = 79, polyarteritis nodosum (n = 55, and Churg-Strauss syndrome (n = 49 were examined; 55 autopsies were analyzed in patients with the above diseases. Results. Fifty-one (15.6% of the 321 patients were diagnosed as having cardiovascular diseases (CVD: angina pectoris (7.1% and MI (3.1% and endovascular interventions (0.9%. The risk of cardiovascular events was found to be associated with traditional risk factors, such as male gender and age. Arterial hypertension, hypercholesterolaemia, and increased serum creatinine were more frequently detected in the CVD group that showed no significant differences from the non-CVD group. According to autopsy results, atherosclerosis was identified in the patients with Wegener's granulomatosis (52%, Takayasu's arteritis (50%, polyarteritis nodosum (52.6%, and Churg-Strauss syndrome (57.1%. Conclusion. CVD and atherosclerosis are common in systemic vasculitides, which requires the traditional risk factors of atherosclerosis to be actively corrected.

    The granuloma gangraenescens in the oral, maxillary and facial region is a rare disease. It is a destroying process in the region of palate, nose, paranasal sinuses, cheeks and orbit with characteristic signs of granulomatosis, infection and malignancy. The disease shows often a lethal development with cachexia or sepsis. Besides local inflammations and tumors, the granulomatosis of Wegener, and the so-called necrotizing sialometaplasia are above all to be excluded by differential diagnosis. Five cases are presented in order to describe the diagnostic and therapeutic problems. In literature, the greatest efficacy is attributed to radiotherapy, however, a detailed definition of the most efficient irradiation conditions cannot be given yet because of the small number of cases. Good long-term results or recoveries can be achieved in 75 to 80% of cases by a relatively high radiation dose of 40 to 50 Gy administered within four to five weeks. During the observation time of two to six years, no one of the five patients treated here only by megavoltage therapy showed a recurrence.

    The reversed halo sign is characterised by a central ground-glass opacity surrounded by denser air–space consolidation in the shape of a crescent or a ring. It was first described on high-resolution CT as being specific for cryptogenic organising pneumonia. Since then, the reversed halo sign has been reported in association with a wide range of pulmonary diseases, including invasive pulmonary fungal infections, paracoccidioidomycosis, pneumocystis pneumonia, tuberculosis, community-acquired pneumonia, lymphomatoid granulomatosis, Wegener granulomatosis, lipoid pneumonia and sarcoidosis. It is also seen in pulmonary neoplasms and infarction, and following radiation therapy and radiofrequency ablation of pulmonary malignancies. In this article, we present the spectrum of neoplastic and non-neoplastic diseases that may show the reversed halo sign and offer helpful clues for assisting in the differential diagnosis. By integrating the patient's clinical history with the presence of the reversed halo sign and other accompanying radiological findings, the radiologist should be able to narrow the differential diagnosis substantially, and may be able to provide a presumptive final diagnosis, which may obviate the need for biopsy in selected cases, especially in the immunosuppressed population.

    Full Text Available Introduction: Epstein-Barr virus positive mucocutaneous ulcer (EBVMUC is a rare, newly described provisional entity in the 2016 Update of World Health Organization classification of lymphoid neoplasms. The histomorphological and immunophenotypical and molecular features overlap with classical Hodgkin’s lymphoma (cHL and can be mistaken for the same. Case report: A 70-year-old male, a known case of diabetes mellitus and hypertension, was diagnosed with Wegener’s granulomatosis (granulomatosis with polyangiitis in 2007. He was treated with prednisolone and cyclophosphamide, the latter drug was replaced with azathioprine in 2010. He was apparently well since then, until he presented in 2016 with an anal ulcer with a fistula tract formation, the ulcer on histomorphology and immunohistochemistry was diagnosed as EBVMUC. Discussion: EBVMUC was first described in patients with iatrogenic induced immunosuppression.They have later been found to be associated with various other causes of immunosuppression, like solid organ transplant recipients and human immunodeficiency virus (HIV, common factor in all these being immunosuppression. Conclusion: The importance of recognizing this entity lies in its morphological and immunophenotypic overlap with classical Hodgkin’s lymphoma (cHL and unlike latter, most often complete resolution of disease occurs with reduction of immunosuppressive dose. Therefore, correct recognition of the entity is essential to avoid overtreatment as lymphoma.

    Full Text Available Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis, some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic. The patient questioning, physical examination and laboratory assessment about rheumatic and infectious diseases were negative. There was a metallic smell in the breath during the physical examination. The analysis showed serum nickel level at 31 μg/l and urine nickel at 18 μg/l (84.11 μg/g creatinine. Other possible serum and urine heavy metal levels were within normal ranges. Nickel exposure is usually together with other heavy metals (chromium or cadmium, it is rarely alone. Nickel ingested by inhalation usually leads to respiratory problems such as reduced olfactory acuity, ulcers, septum perforation or tumors of the nasal sinuses. This case demonstrates the importance of occupational anamnesis and awareness of diagnosis. Int J Occup Med Environ Health 2017;30(6:963–967

    Full Text Available Crohn′s disease is a granulomatous inflammatory bowel disease and was described in 1932 as a chronic granulomatous disorder of the terminal ileum and is now considered a distinct member of the inflammatory bowel disease family. It may affect any part of the gastrointestinal tract. Oral Crohn′s disease has been reported frequently in the last three decades with or without intestinal manifestations. In the latter case, it is considered as one of the orofacial granulomatosis. There has been much doubt whether intestinal manifestations of Crohn′s disease will eventually develop in the orofacial granulomatosis. We present a female patient aged 22 years with prominent clinical findings such as persistent swelling of lower and upper lip with fissuring and angular cheilitis, granulomatous gingival enlargement, and cobblestone or corrugated appearance of labial mucosa, which are suggestive of Crohn′s disease, but with no evidence of other gastrointestinal involvement. The patient underwent surgical treatment with external gingivectomy procedure. A 6-month follow-up showed minimal recurrence.

  4. Anti-proteinase 3 anti-neutrophil cytoplasm autoantibodies recapitulate systemic vasculitis in mice with a humanized immune system.

    Evidence is lacking for direct pathogenicity of human anti-proteinase-3 (PR3) antibodies in development of systemic vasculitis and granulomatosis with polyangiitis (GPA, Wegener\\'s granulomatosis). Progress in study of these antibodies in rodents has been hampered by lack of PR3 expression on murine neutrophils, and by different Fc-receptor affinities for IgG across species. Therefore, we tested whether human anti-PR3 antibodies can induce acute vasculitis in mice with a human immune system. Chimeric mice were generated by injecting human haematopoietic stem cells into irradiated NOD-scid-IL2Rγ⁻\\/⁻ mice. Matched chimera mice were treated with human IgG from patients with: anti-PR3 positive renal and lung vasculitis; patients with non-vasculitic renal disease; or healthy controls. Six-days later, 39% of anti-PR3 treated mice had haematuria, compared with none of controls. There was punctate bleeding on the surface of lungs of anti-PR3 treated animals, with histological evidence of vasculitis and haemorrhage. Anti-PR3 treated mice had mild pauci-immune proliferative glomerulonephritis, with infiltration of human and mouse leukocytes. In 3 mice (17%) more severe glomerular injury was present. There were no glomerular changes in controls. Human IgG from patients with anti-PR3 autoantibodies is therefore pathogenic. This model of anti-PR3 antibody-mediated vasculitis may be useful in dissecting mechanisms of microvascular injury.

    2014-10-01

    Full Text Available As ressecções intestinais em países desenvolvidos ocorrem devido às malformações congênitas. Em países em desenvolvimento essas resseções ocorrem por causas potencialmente evitáveis, como invaginação intestinal irredutível, trauma abdominal fechado, volvo de jejuno-íleo, enterocolite necrosante, hérnia inguinal estrangulada e obstrução por bridas pós-operatórias. O volvo intestinal na infância é raro e geralmente de causas iatrogênicas causado, por exemplo, pela presença de grampos soltos a cavidade intestinal após apendicectomia laparoscópica. O volvo de jejuno-íleo pode ser secundário à isquemia nos casos de gastrosquise tratadas com silo ou mesmo pela colocação de banda gástrica pós-laparoscopia, ou ainda pela presença de lipoma mesentérico. Não foi identificado trabalho na literatura recente sobre volvo jejuno-íleo e isquemia e necrose de segmento de alça intestinal. O autores relatam um caso de abdome agudo obstrutivo em criança de 6 anos, em pós-operatório tardio (4 anos de apendicectomia aberta e cuja ressecção de segmento de Alça intestinal foi necessária nas duas oportunidades mas por motivos diferentes. Situações adversas em abdome agudo pós-operatório podem não ser por aderências intestinais, mas por situações mais graves e o cirurgião deve estar preparado para corrigir sua tática operatória.

    Full Text Available São apresentados três casos de acropatia úlcero-mutilante familial, também conhecida como doença de Thévenard e/ou neuropatía radicular sensitiva hereditária de Denny-Brown. Após ser salientado o caráter familial da moléstia e analisado o aspecto estereotipado das manifestações sensitivo-tróficas, é apresentada a árvore genealógica da família em estudo. Na patogenia da acropatia úlcero-mutilante familial, que é ainda obscura, é ressaltada sua possível identidade com as moléstias heredodegenerativas. Pelos dados da literatura a lesão siringomiélica é afastada pelos estudos anatomopatológicos. No diagnóstico diferencial é lembrada, principalmente em nosso meio, a neuroleprose, além de outras moléstias nas quais ocorre mal perfurante plantar. Finalmente, é lembrada a evolução da moléstia que se faz por surtos necrosantes sucessivos nas extremidades distais, e o tratamento, que é meramente sintomático.Three cases of ulcero-mutilating familial acropathy (also known as Thévenard's disease or heredo-sensitive radicular neuropathy of Denny-Brown are reported. The familial features of the disease are stressed and a genealogic study of the family is made. The similarity of sensitive-trophic lesions in all cases is noteworthy. The obscure pathogenesis has some features in common with heredodegenerative conditions. According to bibliographic references, syringomielia as a cause of the disease may be excluded by histopathologic data. Differential diagnosis must include leprosy and some other conditions where plantar ulcers are present. The disease is characterized by recurrent episodes of necrosis of the distal extremities. Treatment is only symptomatic.

    Anti-neutrophil cytoplasmic antibodies (ANCA) vasculitides are immune-mediated disorders that primarily affect small blood vessels of the airway and kidneys. Lung involvement, one of the hallmarks of microscopic polyangiitis and granulomatosis with polyangiitis, is associated with increased mortality and morbidity. In recent years, several retrospective series and case reports have described the association of interstitial lung disease (ILD) and ANCA vasculitis, particularly those positive for ANCA specific for myeloperoxidase. In the majority of these patients pulmonary fibrosis occurs concurrently or predates the diagnosis of ANCA vasculitis. More importantly, these studies have shown that ILD has an adverse impact on the long-term prognosis of ANCA vasculitis. This review focuses on the main clinical and radiologic features of pulmonary fibrosis associated with anti-neutrophil cytoplasmic antibodies. Major histopathology features, prognosis and therapeutic options are summarized. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study was designed to evaluate the clinical usefulness of {sup 123}I-BMIPP myocardial SPECT for detecting cardiac involvement in patients with collagen disease. We studied 12 patients with systemic lupus erythematosus (SLE), 8 with progressive systemic sclerosis (PSS), 6 with polymyositis/dermatomyositis (PM/DM) and 3 with allergic granulomatosis and angiitis (AGA). A 111 MBq of {sup 123}I-BMIPP was intravenously injected at rest, and SPECT images were obtained at 15 min after the injection. Seven of 12 SLE, 6 of 8 PSS, 3 of 6 PM/DM and all 3 AGA patients showed an abnormal tracer uptake. The left ventricular ejection fraction was inversely correlated with a BMIPP abnormality. The regional wall motion abnormality was reduced in regions with reduced tracer uptake. These findings suggest that {sup 123}I-BMIPP imaging could be useful for assessment of cardiac involvement in patients with collagen disease. (author)

    Central diabetes insipidus (DI) can be the outcome of a number of diseases that affect the hypothalamic-neurohypophyseal axis. The causes of the condition can be classified as traumatic, inflammatory, or neoplastic. Traumatic causes include postoperative sella or transection of the pituitary stalk, while infectious or inflammatory causes include meningitis, lymphocytic hypophysitis, and granulomatous inflammations such as sarcoidosis and Wegener's granulomatosis. Various neoplastic conditions such as germinoma, Langerhans cell histiocytosis, metastasis, leukemic infiltration, lymphoma, teratoma, pituitary adenoma, craniopharyngioma, Rathke cleft cyst, hypothalamic glioma, and meningioma are also causes of central DI. In affected patients, careful analysis of these MR imaging features and correlation with the clinical manifestations can allow a more specific diagnosis, which is essential for treatment.

    Full Text Available Sjögren’s syndrome is a chronic autoimmune disease characterized by the presence of lymphocytic infiltrates in exocrine glands, mainly salivary and lacrimal glands, which result in xerophthalmia and xerostomia. About half of the patients develop systemic complications, including lymphoproliferative disorders. We report a case of a 27-year-old woman with a diagnosis of Sjögren’s syndrome and a suspicion of respiratory system involvement in the course of granulomatosis with polyangiitis. Histopathological examination of a skin lesion suggested marginal zone B-cell lymphoma. After pathological and immunohistochemical evaluation of all available previous biopsy samples and the medical documentation the diagnosis of extranodal marginal zone B-cell lymphoma stage IV according to the Ann Arbor classification was rendered. The patient was referred to the Department of Haematology and was treated with R-CVP (cyclophosphamide, vincristine, prednisone, rituximab.

    of individual therapeutic agents is difficult to dissect, but cyclophosphamide has emerged as a major contributor to cancer development because of its direct carcinogenic properties. Awareness of cancer risk in AAV calls for increased implementation of measures to prevent or screen for cancer and development......In this review, we summarise the current understanding of the potential link between cancer and anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), including granulomatosis with polyangiitis (Wegener's; GPA) and microscopic polyangiitis (MPA). As is true for many autoimmune...... or inflammatory rheumatic diseases, AAV diagnosis and therapy are associated with an increased risk of de novo cancer development, likely as a result of impaired immunosurveillance, direct oncogenicity of immunosuppressive agents and perhaps malignant degeneration of tissues undergoing chronic immune stimulation...

    A 15-year-old female, having developed recurrent infections of the upper airway, hoarseness, dyspnea, and nasal congestion, was referred to our department. There was no history of trauma or intubation. The subglottic space was circularly narrowed. The test for c-ANCA was negative. Chest X-ray and renal function were normal. A tracheotomy was performed; the histology showed infiltrating plasma cells, but no signs of vasculitis or granulomatous inflammation. One year later the patient developed acute renal failure. Biopsy of the kidney confirmed Wegener's disease. The laryngeal stenosis completely resolved after therapy with cyclophosphamide. Juvenile Wegener's granulomatosis is extremely rare; the larynx and trachea seem to be involved more frequently in children than in adults. The positive testing of c-ANCA can support the diagnosis; however, even when c-ANCA do not test positive, the disease can never be excluded. Surgical interventions within the larynx or trachea might only be considered after ineffective therapy with immunosuppressive drugs.

    Myocarditis is a major cause of heart disease in young patients and a common precursor of heart failure due to dilated cardiomyopathy. Some auto-immune and/or auto-inflammatory diseases may be accompanied by myocarditis, such as sarcoidosis, Behçet's disease, eosinophilic granulomatosis with polyangiitis, myositis, and systemic lupus erythematosus. However, data concerning myocarditis in such auto-immune and/or auto-inflammatory diseases are sparse. New therapeutic strategies should better target the modulation of the immune system, depending on the phase of the disease and the type of underlying auto-immune and/or auto-inflammatory disease.

    1988-01-01

    The sphenoidal sinus lesions, which were documented by sinus CT, were found in 32 sides of sphenoidal sinus of 19 patients seen in 14 months from January 1984 to February 1986. Sphenoiditis was frequently seen as in 17 % in the all poly-sinusitis, and sphenoidals cysts were seen in 4 side in 3 patients. The indications of the sphenoiditis by CT were thickening of the mucosa and opacificasion with soft tissue density. By sphenoid cysts, no contrast enhancement was seen and margins of the cyst wall were smooth and regular with bone erosion. Since erosion of the bone is also seen in Wegener's granulomatosis and carcinoma, the CT image of the bone erosion is not specific to either of them and does not contribute to the definitive diagnosis of malignancy.

    Pulmonary vasculitides predominantly involve the small arterioles, capillaries and venules and include Wegener's granulomatosis, microscopic polyangiitis and the Churg-Strauss syndrome. Takayasu's arteriitis is a large vessel disease and may affect the main pulmonary arteries causing stenoses and occlusions. Knowledge of the natural course of disease and of clinical manifestations of pulmonary disease is helpful for an understanding of imaging findings. For this reason this article gives an overview not only of radiologic findings in chest X-ray and high resolution CT of the lungs but as well of clinical aspects of pulmonary vasculitides. Next to determination of disease extension the determination of disease activity is in the foreground of diagnostic imaging in vasculitides. Within this context principals of immunosuppressive therapy will be recognized. (orig.)

    Full Text Available Peripheral ulcerative keratitis (PUK is type of crescent-shaped inflammatory damage that occurs in the limbal region of the cornea. PUK is always combined with an epithelial defect and the destruction of the peripheral corneal stroma. PUK may have a connection to systemic conditions, such as long-standing rheumatoid arthritis (RA, systemic lupus erythematosus (SLE, Wegener granulomatosis (WG, relapsing polychondritis, classic polyarteritis nodosa and its variants, microscopic polyangiitis, and Churg-Strauss syndrome. However, the most common connection is with RA, which is also the focus of this review. The pathogenesis of PUK is still unclear. It is thought that circulating immune complexes and cytokines exert an important influence on the progression of this syndrome. Treatment is applied to inhibit certain aspects of PUK pathogenesis.

    Full Text Available Idiopathic pulmonary hemosiderosis (IPH is often an ignored and rare cause of diffuse alveolar hemorrhage (DAH. It is characterized by triad of hemoptysis, anemia, and alveolar opacity on radiology. It is a diagnosis of exclusion, established after ruling out other causes of DAH such as Goodpasture’s syndrome, large vessel vasculitis, small vessel vasculitis associated with anti-neutrophil cytoplasmic antibody (ANCA (Wegener’s granulomatosis, Churg–Strauss syndrome, microscopic polyangiitis, immune complex-related vasculitis (collagen vascular diseases, Henoch–Schönlein purpura, mixed cryoglobulinemia drug reactions, anticoagulation and thrombocytopenia. Though it is a disease primarily affecting children, we hereby report a case of IPH in an adult patient who responded dramatically to oral corticosteroid.

    Churg-Strauss syndrome (CSS) also called allergic granulomatosis and angiitis is a multisystem disorder. Churg-Strauss syndrome is defined as an eosinophil-rich, granulomatous inflammation involving the respiratory tract, along with necrotizing vasculitis affecting small- to medium-sized vessels, and is associated with asthma and eosinophilia. Renal involvement in CSS varies from 26 to 88 % but is usually of mild to moderate stage, and advanced renal failure is uncommon. We encountered an unusual case of 27-year-old man with asthma and primary focal segmental glomerulosclerosis diagnosed as CSS showing myeloperoxidase anti-neutrophil cytoplasmic antibody-associated acute kidney injury with crescentic glomerulonephritis. Patient responded to steroid and cyclophosphamide. Over a follow-up of 2 months, he has no hematuria/eosinophilia and serum creatinine of 2.3 mg/dL has decreased to 1.7 mg/dL.

    Full Text Available Churg-Strauss syndrome (CSS is a rare granulomatous necrotizing small vessel vasculitis characterized by the presence of asthma, sinusitis, and hypereosinophilia. The cause of this allergic angiitis and granulomatosis is unknown. Other common manifestations are pulmonary infiltrates, skin, gastrointestinal, and cardiovascular involvement. No data have been reported regarding the role of immune complexes or cell mediated mechanisms in this disease, although autoimmunity is evident with the presence hypergammaglobulinemia, increased levels of IgE and Antineutrophil cytoplasmic antibody (positive in 40%. We report the case of a 27-year-old lady presenting with painful swelling of predominantly lower limbs with extensive vesicles and ecchymotic patches and fever shortly after stopping systemic steroids taken for a prolonged duration (2002--2010. The aim of this case report is to point to the possibility of CSS in patients presenting with extensive skin lesions masquerading as Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis Syndrome (SJS/TENS.

    Eosinophilic granulomatosis with polyangiitis (EGPA, previously named Churg-Strauss syndrome) is a form of necrotizing vasculitis occurring in patients with asthma and eosinophilia. Ischemic stroke is a relatively rare complication of the disease. We report a case of a 63-year-old woman with multiple embolic infarcts, hypereosinophilia (for >7 years), and skin rash. Elevated cardiac enzymes and cardiac magnetic resonance imaging were consistent with endomyocarditis. The simultaneous presence of history of asthma, sinusitis, hypereosinophilia, and vasculitis led to the diagnosis of EGPA. This case contributes to the recent debate of the 2 possible presentations of the disease according to the ANCA (antineutrophil cytoplasmic antibodies) status. We furthermore underscore the need for careful differential diagnosis of the "ANCA negative" cases with persistent hypereosinophilia from the idiopathic hypereosinophilic syndrome.

    2002-01-01

    Objective: To study the radiographic findings of lymphoproliferative disorders of the lung. Methods: Twenty-five patients with lymphoproliferative disorders of the lung were examined by X-ray film, tomography, and CT. Results: Multiple and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Multiple nodules or masses were observed in 4 patients with pulmonary lymphomatoid granulomatosis. Hilar and mediastinal lymphadenopathy was observed in each patient with angioimmunoblastic lymphadenopathy, 2 patients had multiple nodules or masses, 8 patients had single or multiple patchy infiltrations, 10 had diffuse interstitial infiltrations. 3 patients with Castlemen' disease had a mass in the mediastinum, and another patient had mediastinal lymphadenopathy. Conclusion: Radiographic findings of lymphoproliferative disorders of the lung are varied, and the final diagnosis relies on pathology

    It has been reported that the inhibition of dipeptidyl peptidase-4 (DPP-4)/CD26 on T-cells by DPP-4 enzymatic inhibitors suppresses lymphocyte proliferation and reduces the production of various cytokines, including tumor necrosis factor (TNF)-α. A 72-year-old female with diabetic nephropathy on hemodialysis developed multiple lung nodules following the administration of vildagliptin. A biopsy demonstrated the histology of granulomas without caseous necrosis. The discontinuation of vildagliptin resulted in the disappearance of the granulomas within 4 months. As granulomatosis often develops in patients under anti-TNF-α therapy, the accumulation of DPP-4 inhibitors or its metabolites is possibly linked to unrecognized complications, such as sarcoid-like lung granulomas.

    Available are data obtained at light and electron microscopy of operative specimens from patients with abdominal pseudotuberculosis and animals challenged orally with Yersinia pseudotuberculosis. The authors are the first to outline detailed characteristics of the intestinal and regional lymph node lesion arising in response to the infection and reflecting growing resistance to it. These features of pathological process involve marked tissue eosinophilia, necrosis due to phagocytes rexis, and granulomatosis suggesting a pronounced role in the pathogenesis of the body allergization in the course of infection. It is proposed to consider pseudotuberculosis-related changes in lymph nodes as lymphoblastic (early affection) and granulomatous-necrotic (advanced infection) lymphadenitis. The evidence obtained can promote differential diagnosis of pseudotuberculosis.

    It is widely acknowledged among gastroenterologists that the oral cavity may be involved in Crohn\\'s disease (CD). However, the specific manifestations are poorly appreciated. Although oral aphthous ulceration is probably not diagnostically useful in patients with suspected CD, disease-specific manifestations do occur and are particularly common in children presenting with CD. These manifestations can be subtle, often are subclinical, yet commonly harbor diagnostically useful material (granulomas). Orofacial granulomatosis (OFG) is conventionally used to describe patients with overt oral disease without obvious involvement of the gastrointestinal tract. However, many patients with OFG have subclinical intestinal CD or will progress to develop overt intestinal CD with time. The management of severe oral disease is challenging and lacks a clear evidence base.

    Histoplasmosis is an acquired mycotic disease produced by the histoplasma capsulatum very frequent in Colombia, primarily affecting lungs. The pathogenesis of the histoplasmosis is similar to the one of tuberculosis. From the clinical point of view, this disease has several manifestations including the primary acute and chronic pulmonary forms. Histoplasmoma pulmonary disseminated histoplasmosis, mediastinal compromise due to granulomatosis and fibrosis, as well as ocular histoplasmosis. A clinical case of a 33-year old man is presented who consults for dry coughing of one year of evolution, without any other symptomatology, with a normal chest x-ray and after several studies including chest cat and fiber-bronchoscopy. A pulmonary histoplasmosis was determined by histopathology

    Full Text Available Background. Systemic lupus erythematosus (SLE is an autoimmune disease which is known to present with a wide variety of clinical manifestations. Case Report. A 15-year-old male presented with complaints of moderate grade fever and generalized body swelling. There was no history of cough, weight loss, joint pain, oral ulcerations, skin rash, photosensitivity, loss of hair, pain abdomen, jaundice, or any significant illness in the past. Contrast enhanced computerized tomography of the abdomen revealed hypodense lesions in both liver and spleen (without contrast enhancement, suggestive of granulomas along with few retroperitoneal and mesenteric lymph nodes. On the basis of immunological tests and renal biopsy report, SLE with hepatosplenic granulomatosis diagnosis was made. He was given pulse methylprednisolone 500 mg, for 3 days and he showed dramatic improvement clinically. Conclusion. Hepatic and splenic granulomas are not common in SLE, but this should be kept in differential diagnosis.

    Full Text Available Crohn´s disease is a chronic inflammatory bowel disease still with unknown etiology. In 0.5-20 % of patients, extraintestinal lesions in the oral cavity can be presented in forms of orofacial granulomatosis, cobblestone and corrugated oral mucosa, mucosal tags, deep linear ulcerations with hyperplastic folds, pyostomatits vegetans, aphthous ulcers, angular cheilitis, labial/facial edema and gingival erythema/edema. We describe a case of a 28-year-old male who was presented with oral lesions of Crohn´s disease and treatment procedure. The patient was candidate for biologic treatment so dental procedures and preparation of the patient for treatment are described. Good communication and cooperation between the patient's doctor and dentist are important for successful treatment.

    Objective To quantify the occurrence of features of vasculitis that initially present after diagnosis in 6 types of primary vasculitis. Methods Standardized collection of data on 95 disease manifestations in 6 vasculitides, including granulomatosis with polyangiitis (Wegener's, GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA), polyarteritis nodosa (PAN), giant cell arteritis (GCA), and Takayasu's arteritis (TAK), was performed within a set of multicenter longitudinal, observational cohorts. For each form of vasculitis, the frequency of disease-specific manifestations at diagnosis was compared to the cumulative frequency of each manifestation. The percentage of patients who initially developed “severe” manifestations after diagnosis, defined as organ- or life-threatening in the small and medium vessel vasculitides (GPA, MPA, EGPA, PAN) and as ischemic/vascular in the large vessel vasculitides (GCA, TAK), was reported. Results Out of 838 patients with vasculitis, 490 (59%) experienced ≥ 1 new disease manifestation after diagnosis. On average, patients with vasculitis experienced 1.3 new manifestations after diagnosis (GPA - 1.9, MPA - 1.2, EGPA - 1.5, PAN - 1.2, GCA - 0.7, TAK - 1.0). New severe manifestations occurred after diagnosis in 224 (27%) out of 838 patients (GPA - 26%, MPA - 19%, EGPA - 21%, PAN - 23%, GCA - 24%, and TAK - 44%). Timing of onset of new manifestations was not significantly associated with disease duration. Conclusion A majority of patients with vasculitis develop new disease features after diagnosis, including a substantial number of new, severe manifestations. Ongoing assessment of patients with established vasculitis should remain broad in scope. PMID:23908447

    Published small case series suggest that inflammatory bowel disease [IBD; Crohn's disease (CD) or ulcerative colitis (UC)] and vasculitis co-occur more frequently than would be expected by chance. To describe this association by an analysis of a large cohort of carefully studied patients and through a systematic literature review. Patients with both IBD and vasculitis enrolled in the Vasculitis Clinical Research Consortium (VCRC) Longitudinal Studies, followed in Canadian Vasculitis research network (CanVasc) centers and/or in the University of Toronto's IBD clinic were included in this case series. A systematic literature review of patients with IBD and vasculitis involved a PubMed search through February 2014. The main characteristics of patients with Takayasu arteritis (TAK) and IBD were compared to those in patients with TAK without IBD followed in the VCRC. The study identified 32 patients with IBD and vasculitis: 13 with large-vessel vasculitis [LVV; 12 with TAK, 1 with giant cell arteritis (GCA); 8 with CD, 5 with UC]; 8 with ANCA-associated vasculitis [AAV; 6 granulomatosis with polyangiitis (GPA), 2 with eosinophilic granulomatosis with polyangiitis (EGPA)]; 5 with isolated cutaneous vasculitis; and 6 with other vasculitides. Patients with LVV and AAV were mostly female (18/21). The diagnosis of IBD preceded that of vasculitis in 12/13 patients with LVV and 8/8 patients with AAV. The review of the literature identified 306 patients with IBD and vasculitis: 144 with LVV (133 TAK; 87 with IBD preceding LVV), 19 with AAV [14 GPA, 1 EGPA, 4 microscopic polyangiitis (MPA)], 66 with isolated cutaneous vasculitis, and 77 with other vasculitides. Patients with IBD and TAK were younger and had more frequent headaches, constitutional symptoms, or gastrointestinal symptoms compared to those patients in the VCRC who had TAK without IBD. These findings highlight the risk of vasculitis, especially TAK, in patients with IBD (both CD and UC). Copyright © 2015 Elsevier

    End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center. We conducted a retrospective study of patients followed for chronic renal failure associated with vasculitis before renal transplant. We excluded patients with no biopsy-proven nephropathy. There was no difference in the occurrence of metabolic and cardiovascular complications in our case group compared with the other graft recipients. Infections were frequent and included cytomegalovirus and urinary tract infection. The rates of bacterial and viral infection were equivalent in our population. The incidence of allograft loss was estimated at 1.8%, less than that seen in our entire transplant population. The presence of vasculitis was not significantly related to renal failure (P = .07). Extrarenal relapse occurred in 1 patient with microscopic polyangiitis. Antineutrophil cytoplasmic antibody levels in patients with granulomatosis with polyangiitis and microscopic polyangiitis did not seem to influence the renal outcome (P = .08). Circulating antineutrophil cytoplasmic antibodies were associated with the development of vascular lesions in the graft but were not significantly correlated with graft survival (P = .07). This study supports the theory that renal transplant is an effective treatment option for patients with end-stage renal disease secondary to vasculitis. These patients fare similarly to, if not better than, other patients.

    Systemic vasculitides constitute a heterogeneous group of diseases. Autoimmunity mediated by B lymphocytes and their humoral effector mechanisms play a major role in ANCA-associated vasculitis (AAV) as well as in non-ANCA associated primary systemic vasculitides and in the different types of autoimmune connective tissue disorders and rheumatoid arthritis. In order to detect autoantibodies in systemic vasculitides, we screened protein macroarrays of human cDNA expression libraries with sera from patients with ANCA-associated and ANCA-negative primary systemic vasculitides. This approach led to the identification of antibodies against progranulin, a 88 kDA secreted glycoprotein with strong anti-inflammatory activity in the course of disease of giant-cell arteritis/polymyalgia rheumatica (14/65), Takayasu's arteritis (4/13), classical panarteritis nodosa (4/10), Behcet's disease (2/6) and in the course of disease in granulomatosis with polyangiitis (31/75), Churg-Strauss syndrome (7/23) and in microscopic polyangiitis (7/19). In extended screenings the progranulin antibodies were also detected in other autoimmune diseases such as systemic lupus erythematosus (39/91) and rheumatoid arthritis (16/44). Progranulin antibodies were detected only in 1 of 97 healthy controls. Anti-progranulin positive patients with systemic vasculitides, systemic lupus erythematosus or rheumatoid arthritis had significant lower progranulin plasma levels, indicating a neutralizing effect. In light of the anti-inflammatory effects of progranulin, progranulin antibodies might exert pro-inflammatory effects thus contributing to the pathogenesis of the respective autoimmune diseases and might serve as a marker for disease activity. This hypothesis is supported by the fact that a positive progranulin antibody status was associated with active disease in granulomatosis with polyangiitis. Copyright © 2012 Elsevier Ltd.

  7. NETs: The missing link between cell death and systemic autoimmune diseases?

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available For almost 20 years, apoptosis and secondary necrosis have been considered the major source of autoantigens and endogenous adjuvants in the pathogenic model of systemic autoimmune diseases. This focus is justified in part because initial evidence in systemic lupus erythematosus (SLE guided investigators toward the study of apoptosis, but also because other forms of cell death were unknown. To date, it is known that many other forms of cell death occur, and that they vary in their capacity to stimulate as well as inhibit the immune system. Among these, NETosis (an antimicrobial form of death in neutrophils in which nuclear material is extruded from the cell forming extracellular traps, is gaining major interest as a process that may trigger some of the immune features found in SLE, granulomatosis with polyangiitis (formerly Wegener’s granulomatosis and Felty’s syndrome. Although there have been volumes of very compelling studies published on the role of cell death in autoimmunity, no unifying theory has been adopted nor have any successful therapeutics been developed based on this important pathway. The recent inclusion of NETosis into the pathogenic model of autoimmune diseases certainly adds novel insights into this paradigm, but also reveals a previously unappreciated level of complexity and raises many new questions. This review discusses the role of cell death in systemic autoimmune diseases with a focus on apoptosis and NETosis, highlights the current short comings in our understanding of the vast complexity of cell death, and considers the potential shift in the cell death paradigm in autoimmunity. Understanding this complexity is critical in order to develop tools to clearly define the death pathways that are active in systemic autoimmune diseases, identify drivers of disease propagation, and develop novel therapeutics.

    Atypical manifestations have been described in patients with ANCA-associated vasculitides (AAV), such as pachymeningitis, orbital mass or chronic periaortitis. Because these manifestations have been associated to the spectrum of IgG4-related disease (IgG4-RD), we hypothesized that both diseases could overlap. We conducted a European retrospective multicenter observational study including patients fulfilling ACR and Chapel Hill criteria for AAV and IgG4-RD Comprehensive Diagnostic Criteria. Eighteen patients were included (median age 55.5years, 13 men). AAV and IgG4-RD were diagnosed concomitantly in 13/18 (72%) patients; AAV preceded IgG4-RD in 3/18 (17%) while IgG4-RD preceded AAV in 2/18 (11%). AAV diagnoses included granulomatosis with polyangiitis in 14 (78%), microscopic polyangiitis in 3 (17%), and eosinophilic granulomatosis with polyangiitis in one case. IgG4-RD diagnosis included definite IgG4-RD in 5 (28%) cases, probable IgG4-RD in 5 (28%) and possible IgG4-RD in 8 (44%). IgG4-RD manifestations were chronic periaortitis in 9/18 (50%) patients, orbital mass and tubulointerstitial nephritis in 4 (22%) cases, prevertebral fibrosis in 3 (17%), pachymeningitis and autoimmune pancreatitis in 2 (11%) cases. Patients required median number of 2 (range 0-4) lines of immunosuppressants in combination with glucocorticoids. During the follow-up (median 49,8months, range 17,25-108months), AAV manifestations relapsed in 10/18 (56%) cases and IgG4-RD lesions in 5/18 (28%). When used, mainly for relapses, rituximab showed response in all cases. AAV and IgG4-RD may overlap. Clinicians should consider that atypical manifestations during AAV could be related to IgG4-RD rather than to refractory granulomatous or vasculitic lesions. Copyright © 2017 Elsevier B.V.

    The anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis with renal involvement are associated with high morbi-mortality. In this study we analyse if the prognosis of these diseases have improved in recent years, and which factors influence the outcomes. Retrospective single-centre observational study, which included all patients diagnosed with microscopic polyangiitis and granulomatosis with polyangiitis with renal involvement in the last 25 years. Demographic, clinical and biochemical parameters of prognostic interest were recorded. The differences between four chronological periods were analysed, along with the determinants of a poor outcome (death or end-stage renal disease). Eighty-nine patients were included (mean age 64±15 years). Sixty-four patients (72%) had microscopic polyangiitis and 25 (28%) granulomatosis with polyangiitis. During the study period, 37 (42%) patients died. Through Cox regression analysis, the best determinants of mortality were the initial glomerular filtration rate (HR 0.911; P=.003), Charlson comorbidity index (HR 1.513; P<.0001) and tobacco smoking (HR 1.816; P=.003). 35% developed end-stage renal disease, and the best determinants (by competing-risk regression) were: initial glomerular filtration rate (sub-hazard ratio [SHR]: 0.791; P<.0001), proteinuria (SHR: 1.313; P<.0001), and smoking status (SHR: 1.848; P=.023). No differences were found in patients' mortality or renal survival between the different study periods. Prognosis of anti-neutrophil cytoplasm antibodies vasculitis with renal involvement treated with conventional immunosuppressive therapy remains unsatisfactory, and continues to have increased long-term complications and mortality.

    To assess fertility counseling and preservation practices among children, adolescents, and young adults with rheumatic diseases undergoing cyclophosphamide (CTX) treatment. Retrospective chart review (2006-2016). Academic pediatric center. Male and female patients with systemic lupus erythematosus, Wegener's granulomatosis/granulomatosis with polyangiitis, or other vaculitides, receiving CTX treatment. None. Documentation of fertility counseling and fertility preservation. A total of 58 subjects met the inclusion criteria; 5 were excluded due to incomplete records, thus N = 53. Of these 75% were female (N = 40). Median age was 14 years at diagnosis and 15 years at first CTX treatment. A total of 51% of subjects (69% of males and 45% of females) had no documentation about potential fertility loss before CTX treatment. Among females where fertility counseling was documented, the only fertility preservation option discussed was leuprolide acetate (LA), which was pursued in all of these cases. Of 13 males (77% postpubertal), 3 were offered sperm banking, of whom 2 declined and the other attempted after treatment began and was azoospermic. Of 53 patients, 1 was referred to a fertility specialist. Mean cumulative CTX dose was 9.2 g in males and 8 g in females. Based on these findings, increasing awareness about infertility risk, fertility preservation options, and referral to fertility specialists is needed among pediatric rheumatologists. Prospective studies are needed to assess fertility outcomes in this patient population (including effectiveness of LA with regard to pregnancy rates [PRs]), as well as barriers/facilitators to fertility counseling and fertility preservation.

    Purpose To develop and validate case-finding algorithms for granulomatosis with polyangiitis (Wegener’s, GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA). Methods 250 patients per disease were randomly selected from 2 large healthcare systems using the International Classification of Diseases version 9 (ICD9) codes for GPA/EGPA (446.4) and MPA (446.0). 16 case-finding algorithms were constructed using a combination of ICD9 code, encounter type (inpatient or outpatient), physician specialty, use of immunosuppressive medications, and the anti-neutrophil cytoplasmic antibody (ANCA) type. Algorithms with the highest average positive predictive value (PPV) were validated in a third healthcare system. Results An algorithm excluding patients with eosinophilia or asthma and including the encounter type and physician specialty had the highest PPV for GPA (92.4%). An algorithm including patients with eosinophilia and asthma and the physician specialty had the highest PPV for EGPA (100%). An algorithm including patients with one of the following diagnoses: alveolar hemorrhage, interstitial lung disease, glomerulonephritis, acute or chronic kidney disease, the encounter type, physician specialty, and immunosuppressive medications had the highest PPV for MPA (76.2%). When validated in a third healthcare system, these algorithms had high PPV (85.9% for GPA, 85.7% for EGPA, and 61.5% for MPA). Adding the ANCA type increased the PPV to 94.4%, 100%, and 81.2% for GPA, EGPA, and MPA respectively. Conclusion Case-finding algorithms accurately identify patients with GPA, EGPA, and MPA in administrative databases. These algorithms can be used to assemble population-based cohorts and facilitate future research in epidemiology, drug safety, and comparative effectiveness. PMID:27804171

    Full Text Available Simarouba versicolor é uma árvore semidecídua pertencente à família Simaroubaceae. Um surto de intoxicação por S. versicolor em bovinos por brotos da planta presente no pasto em Mato Grosso do Sul e sua reprodução experimental foram descritos. Esse estudo teve por objetivos verificar experimentalmente se os ovinos podem ser utilizados como modelo clínico-patológico no estudo da intoxicação por Simarouba versicolor St. Hil. (fam. Simaroubaceae, determinar se há indução de resistência pela ingestão de pequenas e repetidas doses e, se a planta mantém sua toxicidade quando dessecada. Foram realizados dois experimentos, sendo o primeiro com folhas verdes ou folhas dessecadas e trituradas de S. versicolor em doses únicas de 5g/kg, 5g/kg e 3g/kg a três ovinos (Ovino 1, 2 e 3 respectivamente. O experimento 2, foi realizado com diferentes doses diárias de folhas dessecadas e trituradas de S. versicolor em quatro ovinos que receberam 1,5g/kg, 0,75g/kg, 0,6g/kg e 0,3g/kg e, com um ovino que recebeu 3g/kg como controle positivo (Ovino 4. A administração foi suspensa quando os ovinos apresentaram sinais clínicos da intoxicação. Após doze dias de recuperação, os animais sobreviventes foram desafiados com a mesma dose diária da planta ingerida anteriormente para avaliar o desenvolvimento de resistência. Os sinais clínicos observados nos dois experimentos caracterizaram-se por anorexia, mucosas oculares congestas, polidipsia, sialorreia, fezes pastosas que evoluíram para diarreia líquida fétida esverdeada, decúbito lateral e morte para os Ovinos 1 a 7. As principais lesões histológicas observadas foram necrose do tecido linfoide (linfonodos, baço, placas de Peyer e enterite necrosante. Com os resultados obtidos, pode-se concluir que os ovinos podem ser utilizados como modelo experimental clínico-patológico na intoxicação por S. versicolor. Com o método utilizado, não houve resistência ao consumo diário de folhas

    Full Text Available Se presenta el caso de un recién nacido de 750 g de peso y 27 semanas de edad gestacional, que durante su evolución en la asistencia respiratoria mecánica, presentó enfisema intersticial pulmonar a tensión en el pulmón derecho, el cual producía desplazamiento mediastinal y pobre aereación del pulmón izquierdo. La subsecuente hipercapnia hizo fracasar todos los intentos de disminuir la presión inspiratoria en la vía aérea proximal y el enfisema intersticial fue empeorando. A los 6 días de vida se decide realizar intubación selectiva del bronquiotronco izquierdo y mantener al paciente con ventilación monopulmonar izquierda durante 36 horas. Al recolocar el tubo en la tráquea y reexpandirse el pulmón derecho, se observó una disminución notable del enfisema intersticial pulmonar y una mejoría gasométrica importante que permitió reducir la intensidad del apoyo ventilatorio. El paciente falleció posteriormente durante una enteritis necrosante.It is presented a case of a newborn of 750 g of weight and 27 weeks of gestational age that during his evolution in the mechanical respiratory assistance had a pulmonary interstitial emphysema on stress in the right lung, which produced mediastinal displacement and poor airing of the left lung. The subsequent hypercapsia made all the attempts to reduce the inspiratory pressure in the proximal air passage fail and therefore, the interstitial emphysema got worse. After the 6th day of life, it was decided to carry out selective intubation of the left bronchial trunk and to mantain the patient with left monopulmonary ventilation during 36 hours. On placing the tube into the trachea again, the right lung reexpanded and it was observed a remarkable decrease of the pulmonary interstitial emphysema and an important gasometric improvement that allowed to reduce that intensity of the ventilatory support. The patient died later due to a necrotizing enteritis.

    Full Text Available A infecção causada pelo vírus Influenza A (IAV é endêmica em suínos no mundo inteiro. O surgimento da pandemia de influenza humana pelo vírus A/H1N1 (pH1N1 em 2009 levantou dúvidas sobre a ocorrência deste vírus em suínos no Brasil. Durante o desenvolvimento de um projeto de pesquisa do vírus de influenza suína em 2009-2010, na Embrapa Suínos e Aves (CNPSA, foi detectado em um rebanho de suínos em Santa Catarina, Brasil, um surto de influenza altamente transmissível causado pelo subtipo viral H1N1. Este vírus causou uma doença leve em suínos em crescimento e em fêmeas adultas, sem mortalidade. Tres leitões clinicamente afetados foram eutanasiados. As lesões macroscópicas incluiam consolidação leve a moderada das áreas cranioventrais do pulmão. Microscopicamente, as lesões foram caracterizadas por bronquiolite necrosante obliterativa e pneumonia broncointersticial. A imunohistoquímica, utilizando um anticorpo monoclonal contra a nucleoproteína do vírus influenza A, revelou marcação positiva no núcleo das células epiteliais bronquiolares. O tecido pulmonar de três leitões e os suabes nasais de cinco fêmeas e quatro leitões foram positivos para influenza A pela RT-PCR. O vírus influenza foi isolado de um pulmão, mais tarde sendo confirmado pelo teste de hemaglutinação (título HA 1:128 e por RT-PCR. A análise das seqüências de nucleotídeos dos genes da hemaglutinina (HA e proteína da matriz (M revelou que o vírus isolado foi consistente com o vírus pandêmico A/H1N1/2009 que circulou em humanos no mesmo período. Este é o primeiro relato de um surto de influenza causado pelo vírus pandêmico A/H1N1 em suínos no Brasil.

    Full Text Available INTRODUÇÃO: As lesões bucais e peribucais são comuns nos pacientes infectados pelo vírus HIV e podem representar os primeiros sinais da doença, antes mesmo das manifestações sistêmicas. OBJETIVO: Este estudo objetivou estimar a prevalência de manifestações bucais em indivíduos soropositivos para o HIV, considerando aspectos sociodemográficos, imunológicos e terapêuticos. MATERIAL E MÉTODO: Foi realizado um estudo de natureza clínico-epidemiológica transversal, entre outubro de 2007 e abril de 2008, com amostra composta por 40 pacientes. Utilizou-se a técnica de observação direta intensiva por meio de exame clínico apropriado. Os dados foram registrados em fichas pré-elaboradas e analisados por estatística descritiva e inferencial. RESULTADO: Verificou-se a prevalência do gênero feminino (52,5%, na faixa etária de 40 a 49 anos (45%. O tratamento com antirretrovirais foi constatado em 85,0% dos casos, sendo todos com terapia de alta potência (HAART. Observou-se que 52,5% dos pacientes apresentaram a contagem de linfócitos TCD4+ acima de 500cél/mm³ e 50,0% apresentaram carga viral indetectável. A prevalência das manifestações bucais foi 42,5%, sendo a mais expressiva a candidose pseudomembranosa (19,23%, seguida da periodontite úlcero-necrosante (15,38%, da leucoplasia pilosa (11,54% e da queilite angular (11,54%. Não foi verificada associação entre manifestações bucais e carga viral (p=0,1268, nem com o número de células T CD4 (p=0,3458. CONCLUSÃO: A prevalência de algumas manifestações bucais associadas à infecção pelo HIV ainda é alta, sendo a candidose pseudomembranosa a infecção mais prevalente, principalmente entre pessoas com baixo nível de escolaridade e maior tempo de infecção pelo vírus HIV, independentemente da terapia utilizada e do estado imunológico do paciente.

MÉTODO: Os neonatos prematuros com idade gestacional inferior a 37 semanas e peso ao nascer inferior a 10% foram alocados aleatoriamente para um regime de nutrição precoce (nas primeiras 24 horas de vida ou tardia (após as primeiras 24 horas de vida. Todos os neonatos apresentaram uma evidência intrauterina de fluxo diastólico reverso ou ausente. Os neonatos incapazes de iniciar uma nutrição precoce foram excluídos. O tempo para a alimentação completa, a progressão da nutrição e morbidez correspondente foram comparados. A eletrogastrografia (EGG foi utilizada para mensurar a motilidade gástrica pré e pós-prandial no segundo e no sétimo dias após o início da nutrição. RESULTADOS: Foram incluídos 60 neonatos no estudo, sendo 30 em cada grupo. Os neonatos incluídos no regime de nutrição precoce atingiram a nutrição enteral completa antes dos neonatos do grupo de controle (98±80-157 em comparação a 172±1 23-261 horas de idade, respectivamente; p = 0,004 e recebiam alta hospitalar antes (p = 0,04. Nenhuma enterocolite necrosante (ECN foi comprovada em ambos os grupos de estudo. A motilidade gástrica melhorou no sétimo dia após o início da nutrição em ambos os grupos de estudo, sem diferença entre eles. CONCLUSÕES: Os neonatos prematuros PIG estáveis em regime de nutrição precoce atingiram alimentação enteral completa e receberam alta hospitalar significativamente antes que aqueles em regime de nutrição tardio, sem morbidez excedente.

    Full Text Available A Aganglionose Intestinal Congênita (AIC, ou Doença de Hirschprung, é uma má formação caracterizada pela ausência de células ganglionares nos plexos mioentérico e submucoso da porção distal do trato gastrointestinal. Assim, o segmento aganglionar é aperistáltico e espástico, constituindo um obstáculo ao transito intestinal e gerando a dilatação do segmento saudável. A doença costuma manifestar-se no período neonatal com obstrução intestinal, distensão abdominal e vômitos. O tratamento é cirúrgico, pela técnica de De La Torre-Mondragon, realizada em um tempo cirúrgico e sem colostomia prévia. Relato do caso: P.R.D., masculino, 33 dias de vida, foi encaminhado ao serviço com quadro de distensão abdominal e parada da eliminação de fezes há 22 horas. Foi internado primeiramente aos cinco dias de vida com quadro de obstrução intestinal, aliviada após limpeza mecânica. Encontrava-se com abdômen distendido, flácido, sem sinais de desconforto à palpação e ruídos hidroaéreos presentes. O enema opaco evidenciou progressão do contraste com dilatação do retossigmoide. A manometria retal demonstrou reflexo inibitório anorretal não desencadeado, com inúmeras evacuações do lactente durante o exame. Foi indicada correção cirúrgica feita pela técnica de De La Torre-Mondragon, sem intercorrências. Anatomopatológico da peça cirúrgica confirmou ausência de células ganglionares no segmento. O diagnóstico preciso e o manejo cirúrgico precoce foi fundamental para evitar a principal complicação desta doença, a enterocolite necrosante. A técnica de De La Torre-Mondragon consiste no rebaixamento transanal endorretal do cólon e permitiu a recuperação do transito intestinal precocemente, sem a necessidade de colostomia. O reestabelecimento precoce do transito intestinal melhorou a qualidade de vida do paciente e diminuiu custos e o tempo de hospitalização.

    Full Text Available Introdução: A gangrena de Fournier é uma infecção polimicrobiana, causado por bactérias aeróbias e anaeróbias.É destrutiva e rapidamente progressiva do tecido subcutâneo e fáscia superficial, caracterizando, portanto, uma fasciite necrosante, acometendo principalmente as regiões perineal,perianal e genital. Caracterizada pela rápida evolução, se não tratada pode evoluir para sepse e falência múltipla dos órgãos. A gangrena de Fournier pode ser idiopática, ou estar relacionada com fatores de risco como: trauma mecânico,procedimentos cirúrgicos,pacientes imunossuprimidos, infecções urinárias ou perianais, diabetes mellitus, entre outras. Objetivo: Relatar o caso de paciente que manifestou a Síndrome de Fournier no Conjunto Hospitalar de Sorocaba. Contribuir com o meio cientifico através da ilustração do caso e seu manejo. Metodologia: As informações contidas nesse trabalho foram obtidas por meio de análise de prontuário, registros fotográficos de métodos diagnósticos, e revisão de literatura. Relato de Caso: Paciente do sexo masculino, 34 anos, diagnosticado com Síndrome de Fournier, iniciada com quadro de dor e edema em testículo esquerdo. Identificada no exame uma lesão ulcerada de 2cm, necrótica, com saída de secreção purulenta em períneo e necrose em escroto. Atualmente, o paciente encontra-se REG, corado, hidratado, AAA, normotenso, eupnéico e com colostomia rósea funcionante. Conclusão: A síndrome descrita acima foi de grande relevância clínica devido à sua rápida evolução no paciente, que culminou com o debridamento das bordas da ferida e a posterior melhora da secreção purulenta, com início de tecido de degranulação sobre a região lesada.

    Full Text Available OBJETIVO: Verificar a influência do local de nascimento e do transporte sobre a morbimortalidade de recém-nascidos prematuros na Região Sul do Brasil. MÉTODOS: Estudo de coorte com recém-nascidos prematuros transferidos para a unidade de tratamento intensivo de referência (grupo transporte = 61, tendo sido acompanhados até a alta. Os dados sobre o atendimento no hospital de origem e transporte foram obtidos no momento da internação. Esse grupo foi comparado com neonatos da maternidade de referência, pareados por idade gestacional (grupo controle = 123, tendo como desfecho primário o óbito e desfechos secundários as alterações da glicemia, temperatura e saturação de oxigênio no momento da internação e a incidência de enterocolite necrosante, displasia broncopulmonar e sepses. Na associação entre as variáveis e o desfecho, foi utilizado o risco relativo. Foi adotado um nível de significância de α = 5% e β = 90%. RESULTADOS: A distância média percorrida foi de 91 km. A idade gestacional média foi de 34 semanas. Entre os recém-nascidos transferidos, 23% (n = 14 não tiveram atendimento pediátrico na sala de parto. No transporte, 33% dos recém-nascidos foram acompanhados por pediatra, e os equipamentos utilizados foram: incubadora (57%, bomba de infusão (13%, oxímetro (49% e aparelho para aferição da glicemia (21%. O grupo transporte apresentou maior incidência de hiperglicemia, risco relativo (RR = 3,2 (2,3-4,4, hipoglicemia, RR = 2,4 (1,4-4,0, hipertermia, RR = 2,5 (1,6-3,9, e hipoxemia, RR = 2,2 (1,6-3,0. Foram observados 18% de óbitos no grupo dos transferidos e 8,9% no grupo controle, RR = 2,0 (1,0-2,6. CONCLUSÕES: A pesquisa expõe deficiências no atendimento e transporte dos recém-nascidos, sendo necessária uma melhor organização do atendimento perinatal e do transporte na região nordeste do Rio Grande do Sul.

    Full Text Available OBJETIVO: Avaliar o impacto do uso de probióticos e prebióticos na saúde das crianças. FONTES DOS DADOS: Foram pesquisados os bancos de dados MEDLINE e LILACS, selecionando-se artigos relevantes em inglês e francês. SÍNTESE DOS DADOS: O leite humano é rico em oligossacarídeos prebióticos e pode conter probióticos. Não existem dados sugerindo que a adição de probióticos a fórmulas para lactentes possa ser prejudicial, mas as evidências de sua eficácia são insuficientes para que seja recomendada. Visto que dados sugerem que a adição de oligossacarídeos prebióticos específicos pode reduzir infecções e atopia em lactentes saudáveis, sua adição parece razoável. Os benefícios a longo prazo dos pro e prebióticos para o sistema imunológico em desenvolvimento ainda precisam ser comprovados. Probióticos selecionados reduzem a duração da diarreia infecciosa em 1 dia, mas faltam evidências quanto à prevenção, exceto na diarreia associada a antibióticos. Alguns probióticos específicos previnem a enterocolite necrosante, e outros micro-organismos podem ser benéficos nos casos de gastrite por Helicobacter pylori e de cólica do lactente. Não há evidências suficientes para recomendar o uso de probióticos na prevenção e no tratamento da dermatite atópica. A utilização de probióticos nos casos de constipação, síndrome do intestino irritável, doença inflamatória intestinal e infecções extraintestinais requer mais estudos. CONCLUSÕES: A duração da administração, a dosagem microbiana e as espécies utilizadas necessitam de maior validação, tanto para probióticos quanto para prebióticos. Alegações de saúde injustificadas são uma grande ameaça ao conceito de pro e prebióticos.

    Full Text Available Wegener’s (granulomatosis with polyangiitis, GPA and Churg-Strauss (eosinophilic polyangiitis, EPA vasculitis are treated as a single variant of systemic necrotizing granulomatosis vasculitis, associated with anti-neutrophil cytoplasmic antibodies (ANCA. There is an urgent need for further study of articular syndrome in patients with ANCA-SV. Objective: to evaluate the incidence and nature of the lesion of the joints at GPA and EPA, connection with extra-articular signs of the disease. Material and methods. The study involved 58 patients with ANCA-SV, among which there were 28 patients with GPA (16 men and 12 women aged from 17 to 70 years old and 30 with EPA (14 men and 16 women aged 19–70 years old.The average duration of the disease in the first and second groups was 4 years and 11 years, respectively. I, II and III degree activity of the GPA were in the ratio 1 : 6 : 7 and in the cases of EPA — 1 : 3 : 4. The lung pathology was diagnosed in all cases with EPA, in patients with GPA — in 68 % of cases. In addition, 2.3 times less frequently cutaneous syndrome was detected. Results. The lesion of the joints in the form of arthritis or arthralgia occurs in 1/2 of the number of patients with granulomatous ANCA-SV in the ratio of HPA to EPA as 1 : 2, which is associated with the severity of extra-articular manifestations of disease, and in cases of EPA — with the level of antibodies to proteinase-3. Patients with EPA significantly more frequently had lesions of the maxillary joints, digital joints of foot, ankle, metatarsophalangeal, hip, sacroiliac and vertebral, and the last 4 were not diagnosed in patients with HPA. Epiphyseal osteoporosis, subchondral sclerosis, osteocytes, artrocalcinosis and changes of the menisci horns of the knee-joints were observed only at EPA. Conclusions. The severity of arthropathy prevails in EPA, compared to GPA, that is associated with great inflammatory degenerative changes of the articular, but intra

    Full Text Available Inflammation involving the uveal tract of the eye, termed uveitis, is frequently associated with various rheumatic disease, including seronegative spondylarthropathies, juvenile rheumatoid arthritis, Crohn’s disease and Behçet’s disease. Scleritis and keratitis may be associated with rheumatoid arthritis and systemic vasculitides such as Wegener’s granulomatosis. Immune-mediated uveitis can have a chronic relapsing course and produce numerous possible complications, many of which can result in permanent vision loss. Treatment typically includes topical or systemic corticosteroids with cycloplegic-mydriatic drugs and/or noncorticosteroid immunosuppressants, but often there is an insufficient clinical effectiveness. Anti-TNFα therapy is promising in the treatment of sight threatening uveitis, particularly in patients with Behçet’s disease. However, there have been also reports of new-onset uveitis during treatment of joint disease with TNFα inhibitors. We describe a case of new-onset uveitis in a patient with rheumatoid arthritis during therapy with etanercept at first and infliximab at last. Although we cannot exclude uveitis as linked to rheumatoid arthritis, it is unlike that the uveitis arises when the joint disease is well controlled. The hypothetical paradoxical effect of anti-TNF is here discussed.

  6. Assessment of Physicochemical Properties of Rituximab Related to Its Immunomodulatory Activity

    Directory of Open Access Journals (Sweden)

    Mariana P. Miranda-Hernández

    2015-01-01

    Full Text Available Rituximab is a chimeric monoclonal antibody employed for the treatment of CD20-positive B-cell non-Hodgkin’s lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis and microscopic polyangiitis. It binds specifically to the CD20 antigen expressed on pre-B and consequently on mature B-lymphocytes of both normal and malignant cells, inhibiting their proliferation through apoptosis, CDC, and ADCC mechanisms. The immunomodulatory activity of rituximab is closely related to critical quality attributes that characterize its chemical composition and spatial configuration, which determine the recognition of CD20 and the binding to receptors or factors involved in its effector functions, while regulating the potential immunogenic response. Herein, we present a physicochemical and biological characterization followed by a pharmacodynamics and immunogenicity study to demonstrate comparability between two products containing rituximab. The physicochemical and biological characterization revealed that both products fit within the same response intervals exhibiting the same degree of variability. With regard to clinical response, both products depleted CD20+ B-cells until posttreatment recovery and no meaningful differences were found in their pharmacodynamic profiles. The evaluation of anti-chimeric antibodies did not show differential immunogenicity among products. Overall, these data confirm that similarity of critical quality attributes results in a comparable immunomodulatory activity.

    2016-01-01

    Eosinophils are multifunctional granular leukocytes that are implicated in the pathogenesis of a wide variety of disorders, including asthma, helminth infection, and rare hypereosinophilic syndromes. Although peripheral and tissue eosinophilia can be a feature of many types of small-vessel and medium-vessel vasculitis, the role of eosinophils has been best studied in eosinophilic granulomatosis with polyangiitis (EGPA), where eosinophils are a characteristic finding in all three clinical stages of the disorder. Whereas numerous studies have demonstrated an association between the presence of eosinophils and markers of eosinophil activation in the blood and tissues of patients with EGPA, the precise role of eosinophils in disease pathogenesis has been difficult to ascertain owing to the complexity of the disease process. In this regard, results of clinical trials using novel agents that specifically target eosinophils are providing the first direct evidence of a central role of eosinophils in EGPA. This Review focuses on the aspects of eosinophil biology most relevant to the pathogenesis of vasculitis and provides an update of current knowledge regarding the role of eosinophils in EGPA and other vasculitides.

    2014-01-01

    Purpose of review Better biomarkers are needed for guiding management of patients with vasculitis. Large cohorts and technological advances had led to an increase in pre-clinical studies of potential biomarkers. Recent findings The most interesting markers described recently include a gene expression signature in CD8+ T cells that predicts tendency to relapse or remain relapse-free in ANCA-associated vasculitis, and a pair of urinary proteins that are elevated in Kawasaki disease but not other febrile illnesses. Both of these studies used “omics” technologies to generate and then test hypotheses. More conventional hypothesis-based studies have indicated that the following circulating proteins have potential to improve upon clinically available tests: pentraxin-3 in giant cell arteritis and Takayasu’s arteritis; von Willebrand factor antigen in childhood central nervous system vasculitis; eotaxin-3 and other markers related to eosinophils or Th2 immune responses in eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome); and MMP-3, TIMP-1, and CXCL13 in ANCA-associated vasculitis. Summary New markers testable in blood and urine have the potential to assist with diagnosis, staging, assessment of current disease activity, and prognosis. However, the standards for clinical usefulness, in particular the demonstration of either very high sensitivity or very high specificity, have yet to be met for clinically relevant outcomes.

    Small-vessel vasculitides are associated with antineutrophil cytoplasmic antibodies (ANCAs). Cytoplasmic ANCAs are targeted mainly against proteinase 3 (PR3), whereas myeloperoxidase (MPO) is the major antigen of perinuclear ANCAs. These relapsing vasculitides show heterogeneous clinical pictures, and disease severity may vary broadly from mild local organ manifestation to acute organ failure (eg, renal failure). We tested whether two cytokine polymorphisms in the interleukin-1beta (IL-1beta) and IL-1 receptor antagonist (IL-1ra) genes, known to determine cytokine secretion, are associated with clinical manifestations and outcome of ANCA-associated vasculitides. Polymerase chain reaction and restriction fragment length polymorphism analyses were performed to determine polymorphisms in the IL-1beta and IL-1ra genes in 79 patients with PR3-ANCA, 30 patients with MPO-ANCA vasculitis, and 196 healthy controls. The frequency of the so-called proinflammatory genotype, characterized by high secretion of IL-1beta and low secretion of its antagonist IL-1ra, was increased significantly in patients with PR3-ANCA with end-stage renal disease. Patients with a renal manifestation of PR3-ANCA vasculitis have an increased risk for developing end-stage renal disease when carrying the proinflammatory IL-1beta/IL-1ra genotype. Anti-inflammatory therapy specifically antagonizing the proinflammatory effect of IL-1beta may be a promising treatment for patients with Wegener's granulomatosis with renal manifestations.

    We investigated the features and the usefulness of gallium scintigraphy in the diagnosis and the assessment of Adult Still's disease (ASD) by retrospective case review. Gallium scintigraphy have been done for 11 cases of ASD (3 males and 8 females) and 4 females were positive. Among these, 67 Ga-citrate was accumulated to the bone marrow in all 4 cases and to the major joints in 2 cases. Positive cases were rather serious and administered more immunosuppressants than negative cases. In order to characterize gallium scintigraphy findings of ASD, i.e. bone marrow accumulation, we analyzed 130 cases of collagen vascular disease. Although 101 cases (77.7%) were positive, only 7 cases (5.4%) showed the accumulation of {sup 67}Ga-citrate to the bone marrow. These include 3 cases with ASD, and 1 case with systemic lupus erythematosus, polyarteritis nodosa, Wegener's granulomatosis and Sjogren's syndrome. We also accumulated 18 patients who exhibited bone marrow accumulation of {sup 69}Ga-citrate, and found that 7 patients had collagen vascular and their related diseases. In conclusion, bone marrow accumulation in gallium scintigraphy is a specific feature of collagen vascular diseases, especially ASD, and it is suggested that cases with positive gallium scintigraphy in ASD can be serious and resistant to treatment.

    Introduction Foreign body in the oral cavity may be asymptomatic for long time and only sometimes it can lead to a typical granulomatous foreign body reaction. Some patients may complain of oral pain and present signs of inflammation with purulent discharge. A granuloma is a distinct, compact microscopic structure composed of epithelioid-shaped macrophages typically surrounded by a rim of lymphocytes and filled with fibroblasts and collagen. Nowadays, the increase of cosmetic invasive procedures such as injection of prosthetic materials in lips and cheeks may lead to unusual forms of inflammatory granulomas. Objectives Describe an unusual presentation of a foreign body reaction in the buccal mucosa due to previous injection of cosmetic agent. Resumed Report A 74-year-old woman was referred to the Department of Otorhinolaryngology, Head and Neck Surgery to investigate the presence of multiple painless, bilateral nodules in the buccal mucosa, with progressive growth observed during the previous 2 months. The histologic results showed a foreign body inflammatory reaction. Conclusion Oral granulomatosis lesions represent a challenging diagnosis for clinicians and a biopsy may be necessary. Patients may feel ashamed to report previous aesthetic procedures, and the clinicians must have a proactive approach.

    The presence of granulomas on tissue biopsie has been reported in a wide range of disorders. The clinical presentation and the diagnostic work-up of granulomatosis can be difficult as it is illustrated in the following report. A 59-year-old patient was referred in 2002 for a granulomatous prostatitis. Physical examination was normal. Except for the increase of prostate-specific antigen (which motivated a biopsy), the laboratory results were normal. Thoracic CT-scan disclosed mediastinal lymph nodes. A minor salivary gland biopsy was consistent with the diagnosis of sarcoidosis. In 2004, the patient presented an epidermal necrolysis, and in 2005 the deterioration of general status raised suspicion of a lymphoproliferative disorder. Liver and bone marrow biopsies revealed a granulomatous process. Despite steroid therapy, the patient died. Autopsy discloses a anaplasic T cell lymphoma. This report illustrates the relationship between sarcoidosis and lymphoma as a mode of presentation, a complication, or an accidental but misleading association? The association between anaplastic lymphoma and sarcoidosis is exceptional.

    Myeloproliferative disorders are a rare cause of focal segmental glomerulosclerosis (FSGS), although the mechanism is unclear. Hydroxyurea is commonly used in these disorders for its cytoreductive properties; however, the effect of this treatment on proteinuria or kidney function remains unclear in cases of myeloproliferative disorder-associated FSGS. We describe the clinical course of a patient with polycythemia vera and nephrotic-range proteinuria, demonstrated to have FSGS on biopsy. The patient had a distant history of granulomatosis with polyangiitis (Wegener's), for which he routinely had his kidney function and proteinuria measured, allowing for early detection of nephrotic syndrome soon after being diagnosed with polycythemia vera. Treatment with hydroxyurea resulted in rapid improvement in proteinuria that correlated with a decrease in hematocrit. This response was replicated 2 additional times when the patient was taken off and then restarted on hydroxyurea therapy. He now maintains a steady dose of hydroxyurea with favorable kidney measures (proteinuria with <1g/d of protein excretion and serum creatinine of 1.27mg/dL [corresponding to estimated glomerular filtration rate of 56mL/min/1.73 m(2)]). This case suggests that early screening and treatment for myeloproliferative disorder-associated FSGS may lead to improved long-standing kidney function.

    2009-01-01

    Epstein-Barr virus (EBV) prevails among more than 90% of the adult population worldwide. Most primary infections occur during young childhood and cause no or only nonspecific symptoms; then the virus becomes latent and resides in lymphocytes in the peripheral blood. Inactive latent EBV usually causes no serious consequences, but once it becomes active it can cause a wide spectrum of malignancies: epithelial tumors such as nasopharyngeal and gastric carcinomas; mesenchymal tumors such as follicular dendritic cell tumor/sarcoma; and lymphoid malignancies such as Burkitt lymphoma, lymphomatoid granulomatosis, pyothorax-associated lymphoma, immunodeficiency-associated lymphoproliferative disorders, extranodal natural killer (NK) cell/T-cell lymphoma, and Hodgkin's lymphoma. The purpose of this article is to describe the spectrum of EBV-related diseases and their key imaging findings. EBV-related lymphoproliferative disorders and lymphomas are especially common in immunocompromised patients. Awareness of their clinical settings and imaging spectrum contributes to early detection and early treatment of possibly life-threatening disorders. (author)

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

  17. Dysphonia – the single symptom of rifampicin resistant laryngeal tuberculosis

    2016-01-01

    Full Text Available Tuberculosis is still the most frequent granulomatous laryngeal disease. Absence of pathognomonic symptoms and change in clinical pattern frequently leads to misdiagnosis and delayed treatment. Hoarseness is the commonest symptom of laryngeal tuberculosis and constitutional symptoms are usually rare. However dysphonia can be caused by many other more common conditions. Hoarseness can be a symptom of organic (nodules and polyps of vocal folds, tumors, vocal fold paresis or functional (functional dysphonia, laryngeal conversion disorder, paradoxical vocal folds motion conditions. Rarely systemic diseases as amyloidosis, sarcoidosis, Wegener’s granulomatosis or tuberculosis can cause vocal dysfunction too. That is why laryngeal tuberculosis is often forgotten in case of persistent hoarseness. In this article, we present a case of a young previously healthy woman, complaining of persistent hoarseness with no other leading symptoms. Though endoscopic image suggested a malignancy, histology showed granulomatous lesion. Detailed examination revealed laryngeal and pulmonary tuberculosis resistant to rifampicin. Conclusion: Dysphonia can be the only one symptom of laryngeal tuberculosis. The disease should be taken into consideration when a patient complains of persistent hoarseness in order to avoid delays in treatment and spread of infection.

    2015-12-01

    Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM. The clinical features of EOM closely resemble localized eosinophilic granulomatosis polyangiitis, therefore it is necessary to be vigilant to the symptoms of mononeuritis, polyneuritis, and skin purpura during diagnosis. Standard treatment for EOM is the instillation of triamcinolone acetonide into the mesotympanum. However, severe cases exhibiting strong inflammation and otorrhea are not easily controlled with antibiotics and/or corticosteroids. We proposed the introduction of a severity score to evaluate the severity of EOM. This score correlated with local IgE levels in middle ear effusion. Clinically, the risk factors associated with this severity score were body mass index, and the duration of bronchial asthma (from the onset of BA to the age of the first consultation of otitis media to our hospital). We emphasize that early diagnosis and adequate treatment are vital in preventing progressive and sudden hearing loss resulting from EOM.

    This research thesis reports the study of the biological reactivity of industrial and environmental aerosols, notably beryllium powder aerosols. In order to study beryllium toxicity under its metal form, and the dose-effect relationship and the suspected carcinogen effect, a pulmonary berylliosis has been experimentally induced in rat and monkey. In order to develop means of rapid detection of exposure and sensitisation to beryllium, the author studied early pathological cellular mechanisms occurring during a pulmonary granulomatosis. Quantitative and qualitative modifications have been searched for, more particularly at the level of endo-alveolar cellular populations of macrophages and lymphocytes. The study has also been extended to the sensitisation of lymphocytes with respect to beryllium. After some generalities about beryllium (properties, sources, uses, exposure sources), and an overview of its toxicity (epidemiology, pathologies, experiments, biological mechanisms, detoxification), the author reports the introduction of a chronic pulmonary berylliosis into animals, discusses the various noticed pathologies and their analysis, and reports in situ and in vitro studies [fr

    Full Text Available Background: Sarcoidosis is a systemic granulomatosis commonly affecting respiratory system. Variable and often unpredictable flow of the disease provides rationale for the development of prognostic algorithm. Aim: To detect predictive parameters in pulmonary and thoracic lymph nodes sarcoidosis; to develop prognostic algorithm. Materials and methods: The results of examination of 113 patients (85 women and 28 men, 19–77 years old with morphologically verified sarcoidosis has been assessed. Clinical manifestations, functional, radiographic (including CT numerical scores and morphological features of the disease were analyzed against 3-year outcomes in prednisolon/hydroxychloroquine-treated or treatment-naive patients. Results: Radiographic stage, CT-pattern scores, several parameters of pulmonary function tests (DLCO, RV, FEV1, FVC and dyspnoe had the greatest prognostic significance for disease flow. Prognostic accuracy was 87.8% and increased to 94.5% after one-year dynamics of symptoms was taken into account. Therapy with systemic glucocorticosteroids did not influence outcomes in sarcoidosis with asymptomatic enlargement of thoracic lymph nodes. Conclusion: We have developed an algorithm for prognosis assessment in pulmonary sarcoidosis. Taking into account the results of patients follow-up significantly improves the accuracy of the prognosis.

    2014-01-01

    Full Text Available Laryngotracheal stenosis (LTS is a rare condition that occurs most commonly as a result of instrumentation of the airway but may also occur as a result of inflammatory conditions or idiopathically. Here, we present the case of a patient who developed LTS as a complication of granulomatosis with polyangiitis (GPA, which was misdiagnosed as asthma for 6 years. After an admission with respiratory symptoms that worsened to the extent that she required intubation, a previously well 14-year-old girl was diagnosed with GPA. Following immunosuppressive therapy, she made a good recovery and was discharged after 22 days. Over subsequent years, she developed dyspnoea and “wheeze” and a diagnosis of asthma was made. When she became pregnant, she was admitted to hospital with worsening respiratory symptoms, whereupon her “wheeze” was correctly identified as “stridor,” and subsequent investigations revealed a significant subglottic stenosis. The delay in diagnosis precluded the use of minimally invasive therapies, with the result that intermittent laser resection and open laryngotracheal reconstructive surgery were the only available treatment options. There were numerous points at which the correct diagnosis might have been made, either by proper interpretation of flow-volume loops or by calculation of the Empey or Expiratory Disproportion Indices from spirometry data.

    Full Text Available Objective. To estimate the incidence rate of clinically apparent arterial thrombotic events and associated comorbidities in patients with primary systemic vasculitis. Methods. Using large cohort administrative data from Quebec, Canada, we identified patients with vasculitis, including polyarteritis nodosa (PAN and granulomatosis with polyangiitis (GPA. Incident acute myocardial infarctions (AMIs and cerebrovascular accidents (CVAs after the diagnosis of vasculitis were ascertained in the PAN and GPA group via billing and hospitalization data. These were compared to rates of a general population comparator group. The incidences of comorbidities (type 2 diabetes mellitus, dyslipidemia, and hypertension were also collected. Results. Among the 626 patients identified with vasculitis, 19.7% had PAN, 2.9% had Kawasaki disease, 23.8% had GPA, 52.4% had GCA, and 1.3% had Takayasu arteritis. The AMI rate was substantially higher in males aged 18–44 with PAN, with rates up to 268.1 events per 10,000 patient years [95% CI 67.1–1070.2], approximately 30 times that in the age- and sex-matched control group. The CVA rate was also substantially higher, particularly in adults aged 45–65. Patients with vasculitis had elevated incidences of diabetes, dyslipidemia, and hypertension versus the general population. Conclusion. Atherothrombotic rates were elevated in patients identified as having primary systemic vasculitis. While incident rates of cardiovascular comorbidities were also increased, the substantial elevation in AMIs seen in young adults suggests a disease-specific component which requires further investigation.

    The incidence of primary systemic vasculitides varies among different geographic regions and ethnic origins. The aim of this study was to examine the incidence rates of vasculitides in the Jerusalem Jewish population, and to examine possible trends in incidence rates over a 20-year period. The clinical databases of inpatients at the 2 medical centers in Jerusalem were searched for patients with vasculitis diagnosed between 1990-2009. Individual records were then reviewed by one of the authors. The significance of trends in incidence rates throughout the study period was evaluated by Pearson correlation coefficient. The average annual incidence rate of polyarteritis nodosa was 3.6/million adults (95% CI 1.6-4.7). Incidence rates did not change significantly during this period (r = 0.39, p = 0.088). The incidence of granulomatosis with polyangiitis (GPA) was 4.1 (2.2-5.9) for the whole period, during which it increased significantly (r = 0.53, p Jerusalem are in the lower range of global incidence rates. While GPA and MPA incidence are increasing, GCA incidence is decreasing.

    Full Text Available Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation. Their role in asthma and parasitic infections has long been recognized. Growing evidence now reveals a role for eosinophils in autoimmune diseases. In this review, we summarize the function of eosinophils in inflammatory bowel diseases, neuromyelitis optica, bullous pemphigoid, autoimmune myocarditis, primary biliary cirrhosis, eosinophilic granulomatosis with polyangiitis, and other autoimmune diseases. Clinical studies, eosinophil-targeted therapies, and experimental models have contributed to our understanding of the regulation and function of eosinophils in these diseases. By examining the role of eosinophils in autoimmune diseases of different organs, we can identify common pathogenic mechanisms. These include degranulation of cytotoxic granule proteins, induction of antibody-dependent cell-mediated cytotoxicity, release of proteases degrading extracellular matrix, immune modulation through cytokines, antigen presentation, and prothrombotic functions. The association of eosinophilic diseases with autoimmune diseases is also examined, showing a possible increase in autoimmune diseases in patients with eosinophilic esophagitis, hypereosinophilic syndrome, and non-allergic asthma. Finally, we summarize key future research needs.

    2012-01-01

    Full Text Available Introduction: Leishmaniasis is classified into three clinical presentations: visceral, coetaneous and mucocutaneous. The latter is usually secondary to hematogenous spread after months or years of skin infection and can manifest as infiltrative lesions, ulcerated or vegetating in nose, pharynx, larynx and mouth, associated or not with ganglionics infarction. Laryngeal involvement is part of the differential diagnosis of lesions in this topography as nonspecific chronic laryngitis, granulomatosis and even tumors of the upper aerodigestive tract presenting atypical evolution. Sometimes it is difficult for the correct diagnosis of Leishmaniasis, with description of cases in the literature were conducted improperly. Objective: The objective of this study is to report a case of laryngeal Leishmaniasis addressing the difficulty of diagnosis, complications and treatment applied. Case Report: A patient with pain throat, dysphagia, odynophagia, dysphonia and weight loss, with no improvement with symptomatic medication. At telelaringoscopy, infiltrative lesion showed nodular supraglottis. He underwent a tracheotomy for airway obstruction and biopsy with immunohistochemical study for a definitive diagnosis of laryngeal Leishmaniasis. The patient was referred to the infectious diseases that initiated treatment with N-methylglucamine antimoniate with satisfactory response to therapy. Final Comments: Faced with a clinical suspicion of granulomatous diseases, it is essential to follow protocol laboratory evaluation associated with histological injury, to get a precise definition etiological without prolonging the time of diagnosis. Medical treatment for mucosal Leishmaniasis, recommended by the World Health Organization, was adequate in the case of laryngeal disorders, with complete resolution of symptoms.

  7. Novel targets of omalizumab in asthma.

    2017-01-01

    Omalizumab is a recombinant humanized anti-IgE monoclonal antibody approved in the US for moderate to severe persistent allergic asthma (severe persistent asthma in the European Union), uncontrolled despite treatment with inhaled corticosteroids and long-acting beta2 agonists. It reduces asthma exacerbations, symptoms, oral corticosteroid doses, and improves quality of life. Omalizumab may have an antiviral effect when used as a preventive therapy for fall exacerbations in children and teenagers. Two proof-of-concept studies have evaluated omalizumab in nonatopic asthma and showed that it is safe and possibly efficacious in some patients. Omalizumab has been successfully studied as add-on to specific immunotherapy in moderate allergic asthma. Its safety in pregnancy has been assessed in the EXPECT registry. Case series also report positive effects in cases of allergic bronchopulmonary aspergillosis, and in nasal disorders frequently associated with asthma. Last, omalizumab may have corticosteroid-sparing effect in a subset of patients with eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome). Recent studies argue in favor of positive effects of omalizumab beyond its current indications in asthma. Well-designed studies are needed in order to demonstrate the safety and efficacy of omalizumab in these possible novel indications.

    The abuse of cocaine can lead to significant destruction of midline craniofacial structures. This process occurs secondary to myriad mechanisms, including ischemic necrosis, irritation by chemical adulterants, and direct trauma during its administration. Coupled with a prolonged chronic infection of intranasal and anterior skull base regions, an encephalocele can be formed. We report a case of an encephalocele secondary to cocaine use and its associated complications. A 56-year-old man presented with altered mental status and cerebritis secondary to the presence of an intranasal encephalocele. On computed tomography, extensive destruction of the anterior cranial fossa was observed. The patient had a 30-year history of intranasal cocaine abuse, and his urine tested positive for the presence of cocaine on admission. The patient was treated with intravenous antibiotics and underwent a repair of his cranial defect and resection of the encephalocele. The patient made a good recovery after treatment. Alternative causes of an encephalocele, including trauma, surgery, and congenital malformation, were ruled out in this patient. Histopathological analysis of the necrotic tissue and the absence of renal or pulmonary disease also indicated that the patient did not suffer from Wegener granulomatosis, a known cause of spontaneous intranasal lesions. To the best of our knowledge, this is the first report of an encephalocele likely induced solely by cocaine abuse.

  9. Pathogenetic and Clinical Aspects of Anti-Neutrophil Cytoplasmic Autoantibody-Associated Vasculitides

    2018-04-01

    Full Text Available Anti-neutrophil cytoplasmic autoantibodies (ANCA targeting proteinase 3 (PR3 and myeloperoxidase expressed by innate immune cells (neutrophils and monocytes are salient diagnostic and pathogenic features of small vessel vasculitis, comprising granulomatosis with polyangiitis (GPA, microscopic polyangiitis, and eosinophilic GPA. Genetic studies suggest that ANCA-associated vasculitides (AAV constitute separate diseases, which share common immunological and pathological features, but are otherwise heterogeneous. The successful therapeutic use of anti-CD20 antibodies emphasizes the prominent role of ANCA and possibly other autoantibodies in the pathogenesis of AAV. However, to elucidate causal effects in AAV, a better understanding of the complex interplay leading to the emergence of B lymphocytes that produce pathogenic ANCA remains a challenge. Different scenarios seem possible; e.g., the break of tolerance induced by a shift from non-pathogenic toward pathogenic autoantigen epitopes in inflamed tissue. This review gives a brief overview on current knowledge about genetic and epigenetic factors, barrier dysfunction and chronic non-resolving inflammation, necro-inflammatory auto-amplification of cellular death and inflammation, altered autoantigen presentation, alternative complement pathway activation, alterations within peripheral and inflamed tissue-residing T- and B-cell populations, ectopic lymphoid tissue neoformation, the characterization of PR3-specific T-cells, properties of ANCA, links between autoimmune disease and infection-triggered pathology, and animal models in AAV.

    Multiple sclerosis (MS) is a neuro-inflammatory, autoimmune disease influenced by environmental and polygenic components. There is growing evidence that the peptide hormone leptin, known to regulate energy homeostasis, as well as its antagonist ghrelin play an important role in inflammatory processes in autoimmune diseases, including MS. Recently, single nucleotide polymorphisms (SNPs) in the genes encoding leptin, ghrelin and their receptors were evaluated, amongst others, in Wegener's granulomatosis and Churg-Strauss syndrome. The Lys656Asn SNP in the LEPR gene showed a significant but contrasting association with these vasculitides. We therefore aimed at investigating these polymorphisms in a German MS case-control cohort. Twelve SNPs in the LEP, LEPR, GHRL and GHSR genes were genotyped in 776 MS patients and 878 control subjects. We found an association of a haplotype in the GHSR gene with MS that could not be replicated in a second cohort. Otherwise, no significant differences in allele or genotype frequencies were observed between patients and controls in this particular cohort. Thus, the present results do not support the hypothesis that genetic variation in the leptin/ghrelin system contributes substantially to the pathogenesis of MS. However, a modest effect of GHSR variation cannot be ruled out and needs to be further evaluated in future studies. Copyright © 2011 Elsevier Ltd. All rights reserved.

    We investigated the features and the usefulness of gallium scintigraphy in the diagnosis and the assessment of Adult Still's disease (ASD) by retrospective case review. Gallium scintigraphy have been done for 11 cases of ASD (3 males and 8 females) and 4 females were positive. Among these, 67 Ga-citrate was accumulated to the bone marrow in all 4 cases and to the major joints in 2 cases. Positive cases were rather serious and administered more immunosuppressants than negative cases. In order to characterize gallium scintigraphy findings of ASD, i.e. bone marrow accumulation, we analyzed 130 cases of collagen vascular disease. Although 101 cases (77.7%) were positive, only 7 cases (5.4%) showed the accumulation of 67 Ga-citrate to the bone marrow. These include 3 cases with ASD, and 1 case with systemic lupus erythematosus, polyarteritis nodosa, Wegener's granulomatosis and Sjogren's syndrome. We also accumulated 18 patients who exhibited bone marrow accumulation of 69 Ga-citrate, and found that 7 patients had collagen vascular and their related diseases. In conclusion, bone marrow accumulation in gallium scintigraphy is a specific feature of collagen vascular diseases, especially ASD, and it is suggested that cases with positive gallium scintigraphy in ASD can be serious and resistant to treatment.

    This report assesses the observed risk of PML in patients treated with the anti-CD20 monoclonal antibody rituximab in the regulatory authority-approved autoimmune indications rheumatoid arthritis (RA), granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA). This was a cumulative analysis of confirmed PML cases in patients receiving rituximab for RA or GPA/MPA from both spontaneous reports and clinical trial sources, as captured in the manufacturer global company safety and clinical databases. Overall reporting rates were calculated and patient case details were summarized. As of 17 November 2015, there were nine confirmed PML cases among patients who had received rituximab for RA and two for GPA. Corresponding estimated reporting rates were 2.56 per 100,000 patients with RA (estimated exposure ≈ 351,396 patients) and < 1 per 10,000 patients with GPA/MPA (estimated exposure 40,000-50,000 patients). In all cases, patients had ≥ 1 potential risk factor for PML independent of rituximab treatment. In the RA population, the estimated reporting rate of PML generally remained stable and low since 2009 despite increasing rituximab exposure. There was no pattern of latency from time of rituximab initiation to PML development and no association of PML with the number of rituximab courses. Global post-marketing safety and clinical trial data demonstrated that the occurrence of PML is very rare among rituximab-treated patients with RA or GPA/MPA and has remained stable over time.

    Wells' syndrome is defined as an inflammatory disorder with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Eosinophilic leukocytoclastic vasculitis shows eosinophilic infiltrates in combination with vasculitic changes. And Churg Strauss Syndrome comprises all three characteristics - eosinophilic infiltrates, vasculitis and flame figures. To determine whether these three diseases are distinct entities or different manifestations of a similar clinicopathologic process. Histopathological samples and clinical courses of 17 patients with eosinophilic infiltrates, flame figures and clinical features of Wells' syndrome were re-evaluated. Histopathologically, we focused on the presence or absence of vasculitic features. Clinically, we included only patients who were diagnosed with Wells' syndrome at least once in the course of their disease. 4 patients were finally diagnosed with Wells' syndrome, 5 with eosinophilic leukocytoclastic vasculitis and 6 with Churg Strauss syndrome. Further, we had one case of an overlap between Wells' syndrome and eosinophilic vasculitis and one case of Wegener granulomatosis. Vasculitic features were found in the samples of all patients. Histologically, we find vasculitic features in typical presentations of Wells' syndrome. Clinically, we find typical features of Wells' syndrome in patients finally diagnosed with eosinophilic leukocytoclastic vasculitis or Churg Strauss syndrome. Furthermore, we have observed and formerly reported 3 patients with progression from Wells' syndrome to Churg Strauss syndrome. Thus, we assume that eosinophilic leukocytoclastic vasculitis might form a bridge between Wells' syndrome and Churg Strauss syndrome.

    Anterior interosseous nerve (AIN) syndrome is typically characterized by forearm pain and partial or complete dysfunction of the AIN-innervated muscles. Although the exact etiology and pathophysiology of the disorder remain unclear, AIN syndrome is increasingly thought to be an inflammatory condition of the nerve rather than a compressive neuropathy because the symptoms often resolve spontaneously following prolonged observation. However, peripheral neuropathy can be 1 of the first symptoms of systemic vasculitis that needs early systemic immunotherapy to prevent extensive nerve damage. Churg-Strauss syndrome (CSS; eosinophilic granulomatosis with polyangiitis) is 1 type of primary systemic vasculitis that frequently damages the peripheral nervous system. CSS-associated neuropathy usually involves nerves of the lower limb, and few studies have reported on the involvement of the upper limb alone. We report on a rare case of low median nerve palsy as the initial manifestation of CSS. The patient recovered well with early steroid treatment for primary systemic vasculitis.

    Full Text Available Our goal was to analyze the possibilities of impro­ving the diagnostics of CSS and to improve the effectiveness of treatment according to the existing literature and our own experience of long-term care for patients with eosinophilic granulomatosis with polyangiitis or Churg-Strauss syndrome (CSS. The medical histories of three female patients aged 26 to 46-years and a 20-year-old male patient were considered. The duration of the disease before the established diagnosis was 5-17 years. Anamnesis and medical documents analysis showed a typical CSS debut in the form of allergic rhinitis, nasal polyps, which were recurrent after polypectomy, and respiratory disorders, which were regarded as bronchitis or bronchial asthma – corresponding to the first phase, also called the prodromal or allergic stage of CSS. The prodromal period lasts up to 10 years or more and is characterized by various allergic manifestations, more often –  pollinosis or bronchial asthma, that is difficult to control. But CSS can be suspected because of low effectiveness of the therapy with inhaled steroids, lack of effect of antibiotics and eosinophilia more than 10% that occurs periodically. Even in the third stage of CSS in systemic manifestations of vasculitis and severe secondary lesions of organs and tissues with functional impairment, constant intake of maintenance doses of corticosteroids and cytostatics allows to achieve stabilization of the process in patients with CSS.

    Full Text Available Churg-Strauss syndrome (CSS is a type of vasculitis of small-to-medium sized vessels. This syndrome is known by a history of bronchial asthma with systemic necrotizing vasculitis and peripheral blood hypereosinophilia. It is currently called eosinophilic granulomatosis with polyangiitis (EGPA. This disease affects both genders and all age groups, but it is very rare among children. CSS diagnosis is based on clinical findings such as asthma, eosinophilia, rhinosinusitis, and signs of vasculitis in major organs. In cases where steroids alone or in combination with other immunosuppressive agents are used as treatment, the outcome and long-term survival are usually satisfying. In comparison with other types of systemic vasculitis, the mortality rate of this syndrome is low. In this study, we present the case of a 7-year-old boy with poorly controlled bronchial asthma since three years of age. This case had developed purpuric skin lesions, sinusitis, arthritis, and weakness of the limbs with symptoms of mononeuritis multiplex at the age of seven. After being admitted to our hospital, a series of studies, including complete blood count-diff, chest X-ray, paranasal sinus radiography, brain magnetic resonance imaging, nerve conduction study, spirometry, and serological tests for autoantibodies, were performed and he was diagnosed with CSS. Thereafter, he received regular corticosteroid therapy in combination with methotrexate, and his symptoms were generally well-controlled with the beginning of the treatment. The clinical characteristics, diagnosis, and management of CSS in children are also reviewed in this study.

    Full Text Available In 2013, Russia registered officially the indications for the use of monoclonal antibodies to B-lymphocytes (rituximab, RTM in systemic vasculitides associated with antineutrophil cytoplasmic antibodies (ANCA-SV. This communication presents the preliminary results of the Russian register of the RTM application in autoimmune diseases (NORMA that has included 50 patients with ANCA-SV treated in 14 cities of the Russian Federation. Twenty-five of 50 (50% patients received repeated courses of RTM. RTM has demonstrated a high efficacy and a good profile of treatment safety in patients with ANCA-SV in real-life national clinical practice. Among 25 patients who had been followed up for over 12 months, the remission was achieved in 92% of cases, a decrease in the ANCA-SV activity was observed in 8%. The efficacy of RTM increased when performing repeated courses, while it has been noted that the positive results can be obtained by prescribing a repeated course of RTM at a reduced dose (500–1000 mg. Prescription of the repeated courses was primarily required in patients with granulomatosis and polyangiitis affecting the lungs. Care should be taken when combining RTM treatment with cytostatics (primarily with cyclophosphamide because of the risk of secondary immunodeficiency and infectious adverse events (AE, which have been the most frequent serious AE (12% in patients with ANCA-SV.

    Churg-Strauss syndrome or more accurately eosinophilic granulomatosis with polyangiitis (EGPA) is a small-vessel necrotizing vasculitis with a characteristic late-onset allergic rhinitis and asthma. The use of hospital morbidity database is an important element of the epidemiological analysis of this rare disease. The present study was undertaken to assess the incidence of EGPA and factors related to its epidemiology in Poland; the first analysis of the kind in Poland, enabling a comparison in the European context. This is a retrospective, population-based study using hospital discharge records with EGPA diagnosis, collected for a National Institute of Public Health survey covering the period from 2008 to 2013. The group consisted of 344 patients (206 females and 138 males) with the first-time hospitalization for EGPA. The major findings are that the annual incidence of EGPA in Poland was 1.5 per million (95% confidence intervals: 1.2-1.8), with the point prevalence of 8.8 per million at the end of 2013. A greater incidence of EGPA was observed in the regions with urban predominance. We conclude that discharge records may be a useful element of epidemiological studies on EGPA.

    Full Text Available To determine the patterns and outcomes of the pauci-immune vasculitis in the nephrology department at hospital La Conception in Marseille, we conducted a retrospective study including all patients with diagnosis of pauci-immune renal vasculitis between January 1, 2000 and December 31, 2007. Among 33 cases, 25 were diagnosed as Wegener granulomatosis (WG, seven as microscopic polyangitis (MPA and one as Churg-Strauss syndrome (SCS. The median age of the patients was 57.7 years and the sex-ratio (M/F was 1.6. The visceral mani-festations included kidneys (100% of patients, lungs (75%, ENT (52% of WG, and nervous system (57% of MPA. The mean serum creatinine at admission was 3.3 mg/dL. Renal biopsies revealed a pauci-immune crescentic gromerulonephritis in 96% of the cases. Two patients with WG received plasmapheresis and seven patients required emergency hemodialysis. Induction therapy comprised cyclophosphamide IV and corticosteroids, while maintenance therapy included azathioprine for the majority of patients. Eighty four percent of the patients experienced complete remission after induction therapy. During maintenance therapy relapses were more frequent among patients with MPA (28% compared to WG cases (12%. After 35 months of follow-up, eight patients ended on chronic hemodialysis, and five patients died. ANCA associated vasculitis are frequent in our patients. Long-term outcomes are relatively good despite a mortality rate of 15% and 25% of the patients entering dialysis after three years of follow-up.

    Epizootic ulcerative syndrome (EUS) caused by the oomycete Aphanomyces invadans is an invasive, opportunistic disease of both freshwater and estuarine fishes. Originally documented as the cause of mycotic granulomatosis of ornamental fishes in Japan and as the cause of EUS of fishes in southeast Asia and Australia, this pathogen is also present in estuaries and freshwater bodies of the Atlantic and gulf coasts of the USA. We describe a mass mortality event of 343 captive juvenile bullseye snakehead Channa marulius collected from freshwater canals in Miami-Dade County, Florida. Clinical signs appeared within the first 2 d of captivity and included petechiae, ulceration, erratic swimming, and inappetence. Histological examination revealed hyphae invading from the skin lesions deep into the musculature and internal organs. Species identification was confirmed using a species-specific PCR assay. Despite therapeutic attempts, 100% mortality occurred. This represents the first documented case of EUS in bullseye snakehead fish collected from waters in the USA. Future investigation of the distribution and prevalence of A. invadans within the bullseye snakehead range in south Florida may give insight into this pathogen-host system.

    Full Text Available IgG4-related disease (IgG4-RD is a multiorgan inflammatory disease in which diverse organ manifestations are linked by common histopathological and immunohistochemical features. Prospective studies of IgG4-RD patients are required to clarify the natural history, long-term prognosis, and treatment approaches in this recently recognized condition. Patients with IgG4-RD have different organ manifestations and are followed by multiple specialties. Divergent approaches to the assessment of patients can complicate the interpretation of studies, emphasizing the critical need for validated outcome measures, particularly assessments of disease activity and response to treatment. We developed a prototype IgG4-RD Responder Index (IgG4-RD RI based on the approach used in the development of the Birmingham Vasculitis Activity Score for Wegener’s granulomatosis (BVAS/WG. The IgG4-RD RI was refined by members of the International IgG4-RD Symposium Organizing Committee in a paper case exercise. The revised instrument was applied retrospectively to fifteen IgG4-RD patients at our institution. Those scores were compared to physician’s global assessment scale for the same visits. This paper describes the philosophy and goals of the IgG4-RD RI, the steps in the development of this instrument to date, and future plans for validation of this instrument as an outcome measure.

    We present four patients with vasculitis manifesting with unusual clinical or pathological features, generating surgical problems. Two cases presented with pulmonary hypertension, with investigations and radiological evidence prompting clinical suspicion of pulmonary thrombo-embolic disease. First case, with an antecedant history of Wegener\\'s granulomatosis (WG), demonstrated following "embolectomy", WG involving the large pulmonary elastic arteries. The second case of inoperable "pulmonary thrombo-embolic disease" was subsequently found at limited post mortem to have giant cell arteritis, which affected widespread small peripheral pulmonary arterial vessels. The other two cases were of aortitis occurring in the background of immune-mediated disease, which had been treated with aggressive immunosuppression regimens. The first of these was a case of Cogan\\'s syndrome complicated by descending aortitis, a rarely reported phenomenon, with co-existent acute endocarditis of the aortic valve leaflets. Most cases of endocarditis in this context occur secondary to and in continuity with ascending aortitis. That this case, and a case of ascending aortitis occurring in the context of relapsing polychondritis occurred in the face of aggressive immunosuppression with an apparent clinical response, underscores the need to not accept a clinical picture at face value. This has implications for clinical management, particularly in the follow-up of surgical prosthetic devices such as grafts which may be used in these cases. All four cases emphasise the continued importance of histology and the post-mortem examination in elucidating previously undetected or unsuspected disease.

    Because reports of bronchiolitis obliterans organizing pneumonia (BOOP) are lacking from the Middle East, we conducted a retrospective review of all histopathologically proven cases of BOOP over 10-year period at three tertiary care hospitals in Riyadh and describe the clinical features and outcome. Charts at the three hospitals were searched using a specific code for BOOP or cryptogenic organizing pneumonia (COP). Lung specimens have to show histological proof of BOOP with a compatible clinical picture. Chest radiographs and high resolution CT scans were reviewed. Twenty cases of biopsy-proven BOOP had well documented clinical and radiograph data. There were 11 males and 9 females (mean age 58 years; range 42-78). The clinical presentation f BOOP was acute or subacute pneumonia-like illness with cough (85%), fever (70%) dyspnea, (85%) and crackles (80%). The most frequent radiological pattern was a bilateral alveolar infiltrate. The most common abnormality on pulmonary function testing (n=14) was a restrictive pattern (11 patients). Most patients (70%) had no underlying cause (idiopathic BOOP). Other associations included thyroid cancer, rheumatoid arthritis, syphilis and Wegner's granulomatosis. Ten patients (50%) had a complete response to steroids, 6 (30%) had a partial response and 3 (15.8) with secondary BOOP had rapid progressive respiratory failure and died. The clinical presentation of BOOP in our patients is similar to other reported series. A favorable outcome occurs in the majority of cases. However, BOOP may occasionally be associated with a poor prognosis, particularly when associated with an underlying disease. (author)

    Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation. Their role in asthma and parasitic infections has long been recognized. Growing evidence now reveals a role for eosinophils in autoimmune diseases. In this review, we summarize the function of eosinophils in inflammatory bowel diseases, neuromyelitis optica, bullous pemphigoid, autoimmune myocarditis, primary biliary cirrhosis, eosinophilic granulomatosis with polyangiitis, and other autoimmune diseases. Clinical studies, eosinophil-targeted therapies, and experimental models have contributed to our understanding of the regulation and function of eosinophils in these diseases. By examining the role of eosinophils in autoimmune diseases of different organs, we can identify common pathogenic mechanisms. These include degranulation of cytotoxic granule proteins, induction of antibody-dependent cell-mediated cytotoxicity, release of proteases degrading extracellular matrix, immune modulation through cytokines, antigen presentation, and prothrombotic functions. The association of eosinophilic diseases with autoimmune diseases is also examined, showing a possible increase in autoimmune diseases in patients with eosinophilic esophagitis, hypereosinophilic syndrome, and non-allergic asthma. Finally, we summarize key future research needs. PMID:28496445

  9. Diagnosing α1-antitrypsin deficiency: how to improve the current algorithm

    Full Text Available Over the past 10–15 years, the diagnosis of α1-antitrypsin deficiency (AATD has markedly improved as a result of increasing awareness and the publication of diagnostic recommendations by the American Thoracic Society (ATS/European Respiratory Society (ERS. Nevertheless, the condition remains substantially underdiagnosed. Furthermore, when AATD is diagnosed there is a delay before treatment is introduced. This may help explain why AATD is the fourth most common cause of lung transplantation. Clearly we need to do better. The ATS/ERS recommend testing high-risk groups, such as: all chronic obstructive pulmonary disease patients; all nonresponsive asthmatic adults/adolescents; all cases of cryptogenic cirrhosis/liver disease; subjects with granulomatosis with polyangitis; bronchiectasis of unknown aetiology; panniculitis and first-degree relatives of patients with AATD. In terms of laboratory diagnosis, measurement of α1-antitrypsin levels will identify patients with protein deficiency, but cannot differentiate between the various genetic subtypes of AATD. Phenotyping is the current gold standard for detecting rare variants of AATD (except null variants, while advances in molecular diagnostics are making genotyping more effective. An accurate diagnosis facilitates the physician's ability to actively intervene with measures such as smoking cessation and perhaps augmentation therapy, and it will also help provide a better understanding of the natural history of the disease.

    The association between the signal transducer and activator of transcription 4 (STAT4) gene rs7574865 single nucleotide polymorphism and different autoimmune diseases remains controversial and ambiguous. We conducted this study to investigate whether combined evidence shows the association between STAT4 rs7574865 polymorphism and autoimmune diseases. Comprehensive Medline search and review of the references were used to get the relevant reports published before September 2011. Meta-analysis was conducted for genotype T/T (recessive effect), T/T + G/T (dominant effect) and T allele in random effects models. 40 studies with 90 comparisons including 32 systemic lupus erythematosus (SLE), 19 rheumatoid arthritis (RA), 3 type 1 diabetes (T1D), 11 Systemeric Sclerosis (SSc), 4 inflammatory bowed diseases (IBD), 3 Primary Sjogren's syndrome (pSS), 4 juvenile idiopathic arthritis (JIA), 2 Primary antiphospholipid syndrome (APS), 1 Autoimmune thyroid diseases, 1 multiple sclerosis, 1 Psoriasis, 1 Wegener's granulomatosis, 1 Type 2 diabetes, and 1 giant cell arteritis disease were available for this meta-analysis. The overall odds ratios for rs7574865 T-allele significantly increased in SLE, RA, T1D, SSc, JIA, and APS (OR = 1.56, 1.25, 1.13, 1.34, 1.25, and 2.15, respectively, P rs7574865 T allele confers susceptibility to SLE, RA, T1D, SSc, JIA, APS, IBD-UC, and pSS patients, supporting the hypothesis of association between STAT4 gene polymorphism and subgroup of autoimmune diseases.

    Chronic beryllium disease (CBD) is a granulomatous disorder that affects the lung after exposure to beryllium. The present study reports short- and long-term evolution of granulomatous and fibrotic components in eight patients with severe CBD receiving corticosteroid therapy. Eight patients with confirmed CBD were studied at baseline, after initial corticosteroid treatment (4-12 months), at relapse and at the final visit. Beryllium exposure, Glu(69) (HLA-DPB1 genes coding for glutamate at position beta69) polymorphism, symptoms, pulmonary function tests (PFT), serum angiotensin-converting enzyme (SACE) and high-resolution computed tomography (HRCT) quantification of pulmonary lesions were analysed. The CBD patients were observed for a median (range) of 69 (20-180) months. After stopping beryllium exposure, corticosteroids improved symptoms and PFT (vital capacity +26%, diffusing capacity of the lung for carbon monoxide +15%), and decreased SACE level and active lesion HRCT score. In total, 18 clinical relapses occurred after the treatment was tapered and these were associated with SACE and active lesion HRCT score impairment. At the final visit, corticosteroids had completely stabilised all parameters including both HRCT scores of active lesions and fibrotic lesions in six out of eight patients. Corticosteroids were beneficial in chronic beryllium disease. They were effective in suppressing granulomatosis lesions in all cases and in stopping the evolution to pulmonary fibrosis in six out of eight patients.

Durante um período de 12 anos, ocorreram 195 internações em 77 pacientes com LESJ e estas foram acompanhadas pela Unidade de Reumatologia Pediátrica do Instituto da Criança do Hospital das Clínicas da Universidade de São Paulo. Onze pacientes (14%, dez do sexo feminino, apresentaram 14 internações (7,1% pelo VVZ. Nesses pacientes, a média de idade foi de 16 anos e 5 meses e a média do tempo de duração do LESJ até a primeira infecção devido ao VVZ foi de 4 anos. Todos os episódios das infecções estavam associados com atividade da doença, que se apresentaram como lesões vesicobolhosas seguindo trajeto nervoso. As regiões do tórax e membros foram mais comumente afetadas. Todos haviam utilizado prednisona e quatro usaram ciclofosfamida EV. Todos receberam aciclovir EV por 7 a 10 dias. Nenhum paciente apresentou neuralgia pós-herpética, infecção bacteriana secundária ou evoluiu para óbito. Entretanto, uma paciente em uso de aciclovir apresentou amaurose aguda por vasculite necrosante retiniana bilateral associado ao VVZ, necessitando de duas aplicações de ganciclovir intravítreo e gamaglobulina EV (2 g/kg/dose, com recuperação parcial da acuidade visual.

Estava restrita ao leito devido à poliartrite crônica com limitação do movimento. Pressões sistólica e diastólica foram maiores que percentil 95 para altura. Relação proteína/creatinina urinária estava 0,39g/dia, e os testes imunológicos foram negativos. Antiestreptolisina O era 1.687UI/mL. A biópsia de pele revelou vasculite necrosante de vasos de pequeno e médio calibre, compatível com poliarterite nodosa. Portanto, foi realizado o diagnóstico de poliarterite nodosa sistêmica. Foi administrada prednisona 2mg/kg/dia com resolução completa das lesões de pele e da artrite, além de melhora da proteinúria (0,26g/dia) após 15 dias. O diagnóstico de poliarterite nodosa sistêmica pediátrica deve ser considerado em pacientes com poliartrite crônica associado a lesões cutâneas vasculíticas, sendo a infecção estreptocócica um importante fator desencadeante.

    Full Text Available OBJETIVO: Verificar a associação de leucomalácia periventricular (LPV e sepse neonatal em recém-nascidos de muito baixo peso (RNMBP. MÉTODOS: Foram incluídos RNMBP com suspeita clínica de infecção nascidos na instituição de 01/08/2005 a 31/07/2007. Foram excluídos óbitos antes dos 14 dias, malformações do sistema nervoso central e infecções congênitas. Foi realizado ultra-som cerebral no terceiro dia e semanalmente até a sexta semana de vida ou alta. LPV foi diagnosticada por hiperecogenicidade difusa periventricular persistente por mais de 7 dias, ou por cistos periventriculares. RNMBP foram divididos em grupos com e sem LPV. Sepse foi definida por manifestação clínica com cultura positiva. Os testes t, Mann-Whitney, qui-quadrado e regressão logística foram usados. RESULTADOS: Foram incluídos 88 RNMBP, sendo que 62 (70,5% sobreviveram e 51 (57,8% tiveram LPV. Os grupos foram semelhantes no peso de nascimento, idade gestacional, escore de Apgar, tipo de parto, SNAPPE-II, presenças de enterocolite necrosante, persistência de canal arterial e óbitos. Sepse e ventilação mecânica foram mais freqüentes no grupo com LPV (23,5 e 2,7%, p = 0,005; 86 e 59%, p = 0,004, respectivamente. Na regressão logística, ambos foram fatores de risco independentes para LPV (p = 0,027 e 0,015, respectivamente. CONCLUSÃO: Corioamnionite é fator de risco definido para LPV.

FONTES DE DADOS: Livros-textos e publicações indexadas no Medline e SciELO nos últimos 20 anos, utilizando-se as palavras chaves: "mesenteric artery", "superior mesenteric artery", "newborn intestinal circulation", "necrotizing enterocolitis", "doppler flow velocimetry". SÍNTESE DOS DADOS: Alterações do fluxo sanguíneo mesentérico são um dos fatores predisponentes da enterocolite necrosante, doença neonatal de alta morbimortalidade que acomete principalmente prematuros. A circulação mesentérica é peculiar no período neonatal tanto em relação ao seu estado basal, quanto à sua resposta frente a estímulos fisiológicos. Variações da irrigação mesentérica podem ser inerentes à própria fase de desenvolvimento vascular intestinal do recém-nascido pré-termo, com possíveis agravos de fatores perinatais como: insuficiência placentária, asfixia, infecção, cateterismo umbilical, drogas (indometacina e cafeína, fototerapia, alimentação artificial e progressão rápida da dieta. A dopplerfluxometria permite o estudo da irrigação de órgãos-alvo e pode quantificar o fluxo sanguíneo, a resistência vascular e predizer situações de risco para doenças do trato gastrintestinal no período neonatal. CONCLUSÕES: O recém-nascido apresenta peculiaridades de irrigação sanguínea gastrintestinal. A dopplerfluxometria da artéria mesentérica superior é um método não invasivo que determina as condições circulatórias no território intestinal.OBJECTIVE:To describe peculiarities of the neonatal mesenteric circulation and to characterize the susceptibility factors to the development of gastrointestinal illnesses and alterations of the superior mesenteric artery

    We investigated the clinical and serological features of patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in Japan using data from a nationwide, prospective, inception cohort study. In total, 156 Japanese patients with newly diagnosed AAV were classified according to the European Medicines Agency (EMEA) algorithm with exploratory surrogate markers for AAV-related non-granulomatous pulmonary lesions, predefined as alveolar haemorrhage and interstitial lung disease (ILD), and their clinical and serological features were evaluated. Using the EMEA algorithm, we identified 14 patients (9.0%) with eosinophilic granulomatosis with polyangiitis (EGPA), 33 (21.2%) with granulomatosis with polyangiitis (GPA), 78 (50.0%) with microscopic polyangiitis and renal-limited vasculitis (MPA/RLV), and 31 (19.9%) with unclassifiable vasculitis. The average ages of patients with EGPA (male/female, 5/9), GPA (12/21), and MPA/RLV (35/43) and unclassifiable (9/22) were 58.0, 63.6, 71.1, and 70.6 years, respectively. Myeloperoxidase (MPO)-ANCA and proteinase-3 ANCA positivity was 50.0% and 0% for EGPA, 54.6% and 45.5% for GPA, 97.4% and 2.6% for MPA/RLV, and 93.5% and 3.2% for unclassifiable, respectively. According to the Birmingham Vasculitis Activity Score (BVAS), cutaneous (71.4%) and nervous system (92.9%) manifestations were prominent in EGPA and ear, nose, and throat manifestations (84.9%) and chest manifestations (66.7%) in GPA. Renal manifestations developed frequently in MPA/RLV (91.0%) and GPA (63.6%). The average serum creatinine levels were 0.71 mg/dL for EGPA, 1.51 mg/dL for GPA, 2.46 mg/dL for MPA/RLV, and 0.69 mg/dL for unclassifiable. The percentages of patients with ILD were 14.3% for EGPA, 9.0% for GPA, 47.4% for MPA/RLV, and 61.3% for unclassifiable. Patients with ILD (n = 61) had significantly lower BVAS (P = 0.019) with fewer ear, nose, and throat and cardiovascular manifestations than patients without ILD (n = 95). MPO

    Full Text Available Introduction: The most frequent complication of A (H1N1 influenza and the leading cause of death was pneumonia with a primary viral or mixed viral and bacterial etiology. 182 patients had died because of a pandemic influenza in Poland by 31st July 2010.Material and Methods: A retrospective study of 6 fatal cases of pandemic influenza, aged 23-41, including 3 women, hospitalised between November 2009 and February 2011 in different Polish medical centres.Results: We present the clinical course of 6 late diagnosed cases of A (H1N1 influenza. All patients presented typical flu-like symptoms in the beginning. 4/6 patients had severe disease risk factors: pregnancy, arthritis, Wegener granulomatosis and obesity. All patients were seen by doctors, no one had received antiviral therapy, 4/5 were treated with antibiotics before they were hospitalized. One patient had nosocomial infection. Patients were admitted to the hospital on the 3rd to 8th day of the disease. They received oseltamivir treatment on the 4th to 9th day. All patients developed pneumonia complicated by acute respiratory distress syndrome. Death appeared between the 4th and 27th day after the onset of symptoms. Autopsies were performed in 5 cases and revealed haemorrhagic pneumonia in 2 patients.Conclusion: Delayed diagnosis and antiviral treatment initiation has a significant impact on mortality in A (H1N1 influenza. During the influenza epidemic, patients presenting typical symptoms should always be suspected of having influenza. Antiviral treatment has to be initiated immediately, especially ifthere are risk factors of severe disease.

    Background: The prognosis of systemic vasculitis, for instance Wegener's granulomatosis (WG), was greatly improved by the introduction of immunosuppressive treatment. However, relapses are frequent and predictors are scarce. 111 In-leukocytes have been found to indicate unknown manifestations of WG and to predict later relapse. We prospectively investigated the value of 99m Tc-Exametazime ( 99m Tc-HMPAO)-labeled leukocytes with regard to specific patterns and for their usefulness in the follow-up of patients with WG. Methods: The vasculitis group consisted of 8 patients with WG and 2 with idiopathic necrotizing glomerulonephritis (ING). Seven patients with different inflammatory diseases served as controls. Leukocyte labeling with 99m Tc-HMPAO was done using a slightly modified Hammersmith protocol. Cell viability after labeling was verified in vivo by the exclusion of early lung and splenic uptake and in vitro by means of propidium iodide and FACS analysis. Static gamma camera images from the head, chest, abdomen, and pelvis were obtained up to 18 hours after injection of approximately 300 MBq 99m Tc-HMPAO-labeled leukocytes. Scintigrams were analyzed visually; for semiquantitative analysis ROIs were drawn over the nasal region, the right lung, kidneys, and liver. Results: Increased nasal leukocyte accumulation was found in 7/8 patients with WG and in 2/2 patients with ING. Of 2 patients who had a relapse 6 months later, one presented with, and one without nasal uptake. The kidney/liver ratio was higher in controls (0.24 ± 0.07 vs. 0.37 ± 0.11, p 99m Tc-HMPAO leukocyte scintigraphy failed to indicate or exclude a later relapse and is therefore not suitable as a diagnostic tool in the management of patients with systemic vasculitis.

    This study determined whether interleukin-10 (IL-10) polymorphisms are associated with susceptibility to vasculitis. A meta-analysis was conducted of the associations between the IL-10 -1082 G/A, -819 C/T, and -592 C/A polymorphisms and the haplotype of the IL-10-1082 G/A, -819 C/T, -592 C/A polymorphisms and vasculitis. A total of 21 comparative studies involving 4121 patients and 5504 controls were considered in the meta-analysis. Meta-analysis revealed no association between the IL-10-1082 G allele and vasculitis in all study subjects (OR = 0.927, 95% CI = 0.780-1.102, p = 0.389). However, disease-specific meta-analysis showed an association between Wegener's granulomatosis (WG) and the IL-10-1082 G allele (OR = 0.729, 95% CI = 0.547-0.971, p = 0.031). Meta-analysis revealed an association between vasculitis and the IL-10-819 C allele (OR = 0.804, 95% CI = 0.706-0.916, p = 0.001) in all study subjects and Behcet's disease (BD) (OR = 0.724, 95% CI = 0.679-0.781, p vasculitis in all study subjects (OR = 0.805, 95% CI = 0.619-0.938, p = 0.005) and BD (OR = 0.718, 95% CI = 0.661-0.781, p vasculitis in Europeans (OR = 1.239, 95% CI = 1.105-1.513, p = 0.035). This meta-analysis showed that IL-10 polymorphisms are associated with vasculitis susceptibility, especially in WG and BD.

    Objective To identify circulating proteins that distinguish between active anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and remission in a manner complementary to markers of systemic inflammation. Methods Twenty-eight serum proteins representing diverse aspects of the biology of AAV were measured before and 6 months after treatment in a large clinical trial of AAV. Subjects (n=186) enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial were studied. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were available for comparison. The primary outcome was the ability of markers to distinguish severe AAV (Birmingham Vasculitis Activity Score for Wegener’s granulomatosis (BVAS/WG)≥3 at screening) from remission (BVAS/WG=0 at month 6), using areas under receiver operating characteristic (ROC) curve (AUC). Results All subjects had severe active vasculitis (median BVAS/WG=8) at screening. In the 137 subjects in remission at month 6, 24 of the 28 markers showed significant declines. ROC analysis indicated that levels of CXCL13 (BCA-1), matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinases-1 (TIMP-1) best discriminated active AAV from remission (AUC>0.8) and from healthy controls (AUC>0.9). Correlations among these markers and with ESR or CRP were low. Conclusions Many markers are elevated in severe active AAV and decline with treatment, but CXCL13, MMP-3 and TIMP-1 distinguish active AAV from remission better than the other markers studied, including ESR and CRP. These proteins are particularly promising candidates for future studies to address unmet needs in the assessment of patients with AAV. PMID:22975753

    Objective To analyse the differences between patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) entered into randomised clinical trials (RCTs) and those followed in large observational cohorts. Methods The main characteristics and outcomes of patients with generalised and/or severe GPA or MPA with a five-factor score ≥1 enrolled in the French Vasculitis Study Group (FVSG) or the US-Canadian-based Vasculitis Clinical Research Consortium cohorts were compared to those enrolled in one of 2 FVSG clinical RCTs (WEG91, WEGENT) or 3 European Vasculitis Society clinical trials (CYCLOPS, CYCAZAREM, IMPROVE). Results 657 patients (65.3% with GPA) in RCTs were compared to 437 in cohorts (90.6% with GPA). RCT patients were older at diagnosis than the cohort patients (56.6±13.9 vs. 46.8±17.3 years), had higher Birmingham vasculitis activity score (19.5±9.1 vs. 16.9±7.4), and more frequent kidney disease (84.0% vs. 54.9%) but fewer ear, nose, and throat symptoms (56.8% vs. 72.2%). At 56 months post-diagnosis, mortality and relapse rates, adjusted for age and renal function, were higher for patients with GPA in RCTs vs. cohorts (10.7% vs. 2.5% [p=0.001] and 22.5% vs. 15.6% [p=0.03], respectively) but similar for patients with MPA (6.2% vs. 6.6% [p=0.92] and 16.6% vs. 10.1% [p=0.39], respectively). Conclusion Patients with GPA or MPA in RCTs and those in observational cohorts show important differences that should be remembered when interpreting results based on these study populations.

    The prognosis of systemic vasculitis, for instance Wegener's granulomatosis (WG), was greatly improved by the introduction of immunosuppressive treatment. However, relapses are frequent and predictors are scarce. 111 In-leukocytes have been found to indicate unknown manifestations of WG and to predict later relapse. We prospectively investigated the value of 99m Tc-Exametazime ( 99m Tc-HMPAO)-labeled leukocytes with regard to specific patterns and for their usefulness in the follow-up of patients with WG. The vasculitis group consisted of 8 patients with WG and 2 with idiopathic necrotizing glomerulonephritis (ING). Seven patients with different inflammatory diseases served as controls. Leukocyte labeling with 99m Tc-HMPAO was done using a slightly modified Hammersmith protocol. Cell viability after labeling was verified in vivo by the exclusion of early lung and splenic uptake and in vitro by means of propidium iodide and FACS analysis. Static gamma camera images from the head, chest, abdomen, and pelvis were obtained up to 18 hours after injection of approximately 300 MBq 99m Tc-HMPAO-labeled leukocytes. Scintigrams were analyzed visually; for semiquantitative analysis ROls were drawn over the nasal region, the right lung, kidneys, and liver. Increased nasal leukocyte accumulation was found in 7/8 patients with WG and in 2/2 patients with ING. Of 2 patients who had a relapse 6 months later, one presented with, and one without nasal uptake. The kidney/liver ratio was higher in controls (0.24 ± 0.07 vs. 0.37 ± 0.11, p 99m Tc-HMPAO leukocyte scintigraphy failed to indicate or exclude a later relapse and is therefore not suitable as a diagnostic tool in the management of patients with systemic vasculitis.

    Background and objectives ANCA-associated vasculitis is commonly found in elderly patients, but there are few data concerning outcome and treatment in the highest age groups. Design, setting, participants, & measurements Consecutive patients (N=151) presenting between 1997 and 2009 were retrospectively included from local registries in six centers in Sweden, the United Kingdom, and the Czech Republic if diagnosed with microscopic polyangiitis or granulomatosis with polyangiitis at age ≥75 years during the study period. Patients were followed until 2 years from diagnosis or death. Data on survival and renal function were analyzed with respect to age, sex, ANCA specificity, renal function, C-reactive protein, comorbidities, and Birmingham Vasculitis Activity Score at diagnosis as well as treatment during the first month. Results Median follow-up was 730 days (interquartile range, 244–730). Overall 1-year survival was 71.5% and 2-year survival was 64.6%. Older age, higher creatinine, and lower Birmingham Vasculitis Activity Score were associated with higher mortality in multivariable analysis. Patients who were not treated with standard immunosuppressive therapy had significantly worse survival. Renal survival was 74.8% at 1 year. No new cases of ESRD occurred during the second year. High creatinine at diagnosis was the only significant predictor of renal survival in multivariable analysis. Conclusions ANCA-associated vasculitis is a disease with substantial mortality and morbidity among elderly patients. This study showed a better prognosis for those who received immunosuppressive treatment and those who were diagnosed before having developed advanced renal insufficiency. PMID:26100457

    In the region of the petrous bone, inner acoustic canal and cerebellopontine angle, a variety of different tissues can be found, such as bony, epithelial, neural and vascular structures. Tumorous or tumor-like lesions, vascular or bony malformations or other pathologies can therefore be found in all of these areas. We discuss various frequently occurring tumorous or tumor-like pathologies including congential lesions, such as mucoceles, inflammatory disorders including osteomyelitis, pseudotumors and Wegener's granulomatosis. Benign non-neoplastic lesions, such as cholesteatoma, cholesterol granuloma, epidermoid and benign neoplastic tumors, such as the most commonly found vestibular schwannoma, meningeoma, paraganglioma, vascular pathologies and finally malignant lesions, such as metastasis, chordoma or chondrosarcoma and endolymphatic sac tumor (ELST) are also discussed. The emphasis of this article is on the appearance of these entities in computed tomography (CT) and more so magnetic resonance imaging (MRI), it provides key facts and typical images and discusses possibilities how to distinguish these pathologies.

    Tracheal stenosis is a debilitating disorder with heterogeneity in terms of disease characteristics and management. Repeated recurrences substantially alter patients' quality of life. There is limited evidence for the use of spray cryotherapy (SCT) in the management of benign airway disease. To report our early results for the use of SCT in patients with benign tracheal stenosis. Data were extracted from the medical records of a consecutive series of patients with benign airway stenosis secondary to granulomatosis with polyangiitis (GPA) (n = 13), prior tracheotomy or tracheal intubation (n = 8), and idiopathic strictures (n = 5) treated from September 1, 2013, to September 30, 2015, at a tertiary care hospital. Airway narrowing was quantified on a standard quartile grading scale. Response to treatment was assessed by improvement in airway caliber and the time interval for reintervention. Delivery of 4 5-second SCT cycles and 2 balloon dilatations. Twenty-six patients (median [range] age, 53 [16-83] years; 20 [77%] female) underwent 48 SCT sessions. Spray cryotherapy was successfully used without any substantial intraoperative or postoperative complications in all patients. In a median (range) follow-up of 11 (1-26) months, all patients had improvement in symptoms. Before the institution of SCT, 23 patients (88%) had grade III or IV stenosis. At the last evaluation after induction of SCT, 4 (15%) had grade III or IV stenosis, with a mean (SD) change of 1.39 (0.51) (P benign tracheal stenosis. Although efficacy evidence is limited for SCT, it may be useful for patients who have experienced treatment failure with conventional modalities. Further analysis of this cohort will determine the physiologic durability of the reported short-term changes. Additional trials are warranted for further evaluation of this modality.

    Full Text Available Abstract Background Management of benign tracheal stenosis (BTS varies with the type and extent of the disease and influenced by the patient's age and general health status, hence we sought to investigate the long-term outcome of patients with BTS that underwent minimally invasive bronchoscopic treatment. Methods Patients with symptomatic BTS were treated with flexible bronchoscopy therapeutic modalities that included the following: balloon dilatation, laser photo-resection, self-expanding metal stent placement, and High-dose rate endobronchial brachytherapy used in cases of refractory stent-related granulation tissue formation. Results A total of 115 patients with BTS and various cardiac and respiratory co-morbidities with a mean age of 61 (range 40-88 were treated between January 2001 and January 2009. The underlining etiologies for BTS were post - endotracheal intubation (N = 76 post-tracheostomy (N = 30, Wegener's granulomatosis (N = 2, sarcoidosis (N = 2, amyloidosis (N = 2 and idiopathic BTS (N = 3. The modalities used were: balloon dilatation and laser treatment (N = 98. Stent was placed in 33 patients of whom 28 also underwent brachytherapy. Complications were minor and mostly included granulation tissue formation. The overall success rate was 87%. Over a median follow-up of 51 months (range 10-100 months, 30 patients (26% died, mostly due to exacerbation of their underlying conditions. Conclusions BTS in elderly patients with co-morbidities can be safely and effectively treated by flexible bronchoscopic treatment modalities. The use of HDR brachytherapy to treat granulation tissue formation following successful airway restoration is promising.

    Ten adult patients with RPCGN (crescents in greater than 70% of glomeruli), primary in 6 and associated with systemic diseases in 4, were treated with PE, associated with oral steroids (P) and cyclophosphamide (C) in all cases and with intravenous methylprednisolone pulses (MP) in 7 cases. Four out of ten patients were anuric and needed dialysis treatment at the start of treatment. Therapeutic benefit, i.e. reversal of the trend to further deterioration and substantial improvement of GFR, was achieved in 8 out of 10 patients (80%), including 2 of 4 anuric patients, and in 7 of those (8) who had still active cellular crescents (87.5%). Similar therapeutic benefit had been achieved only in 10% of a comparable population of 10 patients with RPCGN treated before 1980 with P and C, without PE or MP pulses. It is difficult to establish whether the better therapeutic results in the more recently treated group were due to PE or to MP pulses of to both the new approaches, even though the clinical improvement obtained in all the 3 patients treated with PE without concomitant MP suggest a specific beneficial role for PE. RPCGN is a catastrophic illness characterized by progressive deterioration of kidney function, resulting in oliguria and uremia, usually within weeks or months. The most consistent histopathologic finding is the presence of extensive glomerular crescents resulting from proliferation of the extracapillary epithelial cell lining of Bowman's capsule. It is apparent that RPCGN is not a homogeneous entity, clinically, histologically or immunohistologically, but rather a clinicopathologic syndrome, the features of which may be seen in a variety of systemic disorders, including SLE, polyarteritis nodosa, Wegener's granulomatosis, Henoch-Schönlein purpura, cryoglobulinemia, and subacute bacterial endocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)

    Granulomatosis with polyangiitis (GPA) is a systemic necrotizing vasculitis that is associated with granulomatous inflammation and the presence of anti-neutrophil cytoplasmic antibodies (ANCAs) directed against proteinase 3 (PR3). We previously determined that PR3 on the surface of apoptotic neutrophils interferes with induction of antiinflammatory mechanisms following phagocytosis of these cells by macrophages. Here, we demonstrate that enzymatically active membrane-associated PR3 on apoptotic cells triggered secretion of inflammatory cytokines, including granulocyte CSF (G-CSF) and chemokines. This response required the IL-1R1/MyD88 signaling pathway and was dependent on the synthesis of NO, as macrophages from animals lacking these pathways did not exhibit a PR3-associated proinflammatory response. The PR3-induced microenvironment facilitated recruitment of inflammatory cells, such as macrophages, plasmacytoid DCs (pDCs), and neutrophils, which were observed in close proximity within granulomatous lesions in the lungs of GPA patients. In different murine models of apoptotic cell injection, the PR3-induced microenvironment instructed pDC-driven Th9/Th2 cell generation. Concomitant injection of anti-PR3 ANCAs with PR3-expressing apoptotic cells induced a Th17 response, revealing a GPA-specific mechanism of immune polarization. Accordingly, circulating CD4+ T cells from GPA patients had a skewed distribution of Th9/Th2/Th17. These results reveal that PR3 disrupts immune silencing associated with clearance of apoptotic neutrophils and provide insight into how PR3 and PR3-targeting ANCAs promote GPA pathophysiology.

    Full Text Available OBJECTIVE: IgG4-related disease is an emerging clinical entity which frequently involves tissue within the orbit. In order to appreciate the implications of IgG4 immunostaining, we analyzed gene expression and the prevalence of IgG4- immunostaining among subjects with orbital inflammatory diseases. METHODS: We organized an international consortium to collect orbital biopsies from 108 subjects including 22 with no known orbital disease, 42 with nonspecific orbital inflammatory disease (NSOI, 26 with thyroid eye disease (TED, 12 with sarcoidosis, and 6 with granulomatosis with polyangiitis (GPA. Lacrimal gland and orbital adipose tissue biopsies were immunostained for IgG4 or IgG secreting plasma cells. RNA transcripts were quantified by Affymetrix arrays. RESULTS: None of the healthy controls or subjects with TED had substantial IgG4 staining. Among the 63 others, the prevalence of significant IgG4-immunostaining ranged from 11 to 39% depending on the definition for significant. IgG4 staining was detectable in the majority of tissues from subjects with GPA and less commonly in tissue from subjects with sarcoidosis or NSOI. The detection of IgG4+ cells correlated with inflammation in the lacrimal gland based on histology. IgG4 staining tissue expressed an increase in transcripts associated with inflammation, especially B cell-related genes. Functional annotation analysis confirmed this. CONCLUSION: IgG4+ plasma cells are common in orbital tissue from patients with sarcoidosis, GPA, or NSOI. Even using the low threshold of 10 IgG4+ cells/high powered field, IgG4 staining correlates with increased inflammation in the lacrimal gland based on histology and gene expression.

    Idiopathic inflammatory myopathies (IIM) are heterogeneous autoimmune diseases with wide clinical spectrum that may lead to delayed diagnosis. The aim of this study was to examine the impact of IIM-specific dot-blot assay on diagnostic process of patients presenting with muscular or systemic symptoms evocating of IIM. We collected all the prescriptions of an IIM specific dot-blot assay (8 autoantigens including Jo-1, PL-7, PL-12, SRP, Mi-2, Ku, PM/Scl and Scl-70) over a 38-month period. 316 myositis dot-blot assays (MSD) were performed in 274 patients (156 women, mean age 53±10.6 years) referring for muscular and/or systemic symptoms suggesting IIM. The timing of dot prescription through the diagnostic process was highly variable: without (35%), concomitantly (16%) or after electromyographic studies (35%). Fifty-nine patients (22%) had IIM according to Bohan and Peter's criteria. Among them, 29 (49%) had positive dot (8 Jo-1, 6 PM-Scl, 5 PL-12, 5 SRP, 2 Mi-2, 2 PL-7 and 1 Ku). Various other diagnoses were performed including 35 autoimmune disease or granulomatosis (12%), 19 inflammatory rheumatic disease (7%), 16 non inflammatory muscular disorders (6%), 10 drug-induced myalgia (4%), 11 infectious myositis (4%). Except 11 borderline SRP results and one transient PM-Scl, MSD was positive only in one case of IIM. Dot allowed clinicians to correct diagnosis in 4 cases and improved the diagnosis of IIM subtypes in 4 cases. This study reflects the interest of myositis dot in the rapid diagnosis process of patients with non-specific muscular symptoms leading to various diagnoses including IIM.

    Objective: To explore the pattern of abnormalities seen on MRI in rheumatic patients with neurological manifestations and to interpret the findings in relation to clinical picture. Study Design: Descriptive study. Place and Duration of Study: Rheumatology unit, King Khalid University Hospital, Riyadh, Saudi Arabia from January 2013 to February 2014. Patients and Methods: We prospectively included rheumatic patients with neurological symptoms and signs. The clinical data were correlated with MRI findings by a team comprising of a rheumatologist, neurologist and neuro-radiologist. Data was analyzed using simple statistical analysis. Results: Fifty patients were recruited with a mean age of 36.4 ± 10.76 years (range 17-62). Among SLE patients with seizures, focal deficit and headache white matter hyperintensities were found in 9 (64.28%), 4 (50%), 4 (80%) patients respectively. Out of seven SLE patients with global dysfunction, 3 (42.85%) had brain atrophy and 2 (28.57%) normal MRI. In Behcet disease with focal deficit, 3 (75%) patients had white matter hyperintensities and 1 (25%) had brainstem involvement. In Behcet disease with headache, 2 (50%) had normal MRI, 1 (25%) brainstem hyper-intensities and 1 (25%) had subacute infarct. Two (66%) of three Primary APS patients had white matter hyperintensities while third (33%) had old infarct. Both patients of polyarteritisnodosa, had white matter hyperintensities. Out of two Wegener granulomatosis one had white matter hyperintensities and other had ischemic changes in optic nerves. The only one scleroderma patient had white matter hyperintensities. Conclusion: We found that white matter hyperintensities was the most common MRI abnormality in our study group which in most of the cases had poor clinical correlation. No distinct pattern of CNS involvement on MRI was observed in various rheumatic disorders. (author)

    Churg-Strauss (CSS) syndrome is rare and of unknown etiology. It is associated with vasculitis, blood eosinophilia and granulomatosis, and affects multiple organs and systems at various stages of the disease. Specific diagnostic and monitoring tests are not yet available. This study aims to assess the changes in MMP-2 and MMP-9 along with the histopathological alterations in two cases of CSS, as possible potential diagnostic and monitoring criteria. Two adult male patients were diagnosed with CSS in the otorhinolaryngology clinic in the University of Palermo, based on multiple clinical and histopathologic criteria. Biopsies of respiratory mucosa were taken after the consent of the patients, processed for routine histopathology and immunohistochemistry as well as quantitative polymerase chain reaction (qPCR). Similar biopsies were also taken from a non- CSS patient. The Assessment of MMP-2 and MMP-9 was performed using both immunohistochemistry and qPCR techniques. Histopathological alterations in the respiratory mucosa were consistent with vasculitis and granulomatous tissue formation, in addition to inflammatory cell infiltration with abundance of eosinophils. Immunohistochemistry assay performed on the samples derived from the two CSS patients showed a relative and remarkable increase of both MMP-2 and MMP-9 compared to controls. Such an increase was consistent with the qPCR results which depicted a significant increase between 20 and 30% for both MMP-2 and MMP-9, respectively. Since the secretion of MMPs is an essential step in angiogenesis, could these enzymatic factors be used as parameters to diagnose or monitor the evolution of CSS? The small number of samples analyzed in this study does not allow us to suggest a general statement correlating the increase in expression of MMP-2 and MMP-9 to the appearance or evolution of vasculitis; it is only speculative.

    Pulmonary hemorrhage (PH) occurs in 2-5% of SLE patients, and is associated with a high mortality rate (79-90%). Diagnostic criteria for this complication include: 1) Pulmonary infiltrates, with at least ¾ of lung tissue involved in a chest x ray, 2) Acute respiratory failure, 3) A decrease of 3g/dL or more in hemoglobin levels. PH might lead to organized pneumonia, collagen deposition, and pulmonary fibrosis which in time might cause changes in pulmonary function tests with either restrictive or obstructive patterns. To evaluate the existence of abnormalities in pulmonary function tests after a PH episode. We included patients with SLE and primary vasculitis that developed PH. During the acute episode, we measured SLEDAI in SLE patients, five factor score in microscopic polyangiitis (MPA) and Birmingham Vasculitis Activity Store (BVAS) in granulomatosis with polyangiitis (GPA) (Wegener). We determined the number of PH events, treatment, and ventilator assistance requirements and correlated its association with abnormal pulmonary function tests. We included 10 patients, 7 with SLE, 2 with MPA and 1 with GPA (Wegener). The mean activity measures were: SLEDAI 20.4 ± 7.5, FFS 2, and BVAS 36. Treatment consisted in methylprednisolone (MPD) in 3 patients, MPD plus cyclophosphamide (CY) in 6 patients, and MPD, CY, IV immunoglobulin, and plasmapheresis in one patient. Five patients required ventilatory support. We found abnormalities in pulmonary function tests in 8 patients, three had an obstructive pattern and five a restrictive pattern; 2 patients did not show any change. We did not find a significant association with any of the studied variables. PH might cause abnormalities in pulmonary function tests and prolonged immunosuppressive treatment could be required.

    Objective IgG4-related disease is an emerging clinical entity which frequently involves tissue within the orbit. In order to appreciate the implications of IgG4 immunostaining, we analyzed gene expression and the prevalence of IgG4- immunostaining among subjects with orbital inflammatory diseases. Methods We organized an international consortium to collect orbital biopsies from 108 subjects including 22 with no known orbital disease, 42 with nonspecific orbital inflammatory disease (NSOI), 26 with thyroid eye disease (TED), 12 with sarcoidosis, and 6 with granulomatosis with polyangiitis (GPA). Lacrimal gland and orbital adipose tissue biopsies were immunostained for IgG4 or IgG secreting plasma cells. RNA transcripts were quantified by Affymetrix arrays. Results None of the healthy controls or subjects with TED had substantial IgG4 staining. Among the 63 others, the prevalence of significant IgG4-immunostaining ranged from 11 to 39% depending on the definition for significant. IgG4 staining was detectable in the majority of tissues from subjects with GPA and less commonly in tissue from subjects with sarcoidosis or NSOI. The detection of IgG4+ cells correlated with inflammation in the lacrimal gland based on histology. IgG4 staining tissue expressed an increase in transcripts associated with inflammation, especially B cell-related genes. Functional annotation analysis confirmed this. Conclusion IgG4+ plasma cells are common in orbital tissue from patients with sarcoidosis, GPA, or NSOI. Even using the low threshold of 10 IgG4+ cells/high powered field, IgG4 staining correlates with increased inflammation in the lacrimal gland based on histology and gene expression. PMID:25303270

    A series of destructive and tumefactive lesions of the midline structures have been recently added to the spectrum of IgG4-related disease (IgG4-RD). We examined the clinical, serological, endoscopic, radiological, and histological features that might be of utility in distinguishing IgG4-RD from other forms of inflammatory conditions with the potential to involve the sinonasal area and the oral cavity. We studied 11 consecutive patients with erosive and/or tumefactive lesions of the midline structures referred to our tertiary care center. All patients underwent serum IgG4 measurement, flow cytometry for circulating plasmablast counts, nasal endoscopy, radiological studies, and histological evaluation of tissue specimens. The histological studies included immunostaining studies to assess the number of IgG4 + plasma cells/HPF for calculation of the IgG4+/IgG + plasma cell ratio. Five patients with granulomatosis with polyangiitis (GPA), three with cocaine-induced midline destructive lesions (CIMDL), and three with IgG4-RD were studied. We found no clinical, endoscopic, or radiological findings specific for IgG4-RD. Increased serum IgG4 and plasmablasts levels were not specific for IgG4-RD. Rather, all 11 patients had elevated blood plasmablast concentrations, and several patients with GPA and CIMDL had elevated serum IgG4 levels. Storiform fibrosis and an IgG4+/IgG + plasma cell ratio >20% on histological examination, however, were observed only in patients with IgG4-RD. Histological examination of bioptic samples from the sinonasal area and oral cavity represents the mainstay for the diagnosis of IgG4-RD involvement of the midline structures.

    Full Text Available Introduction Potassium iodine (KI is used as a drug therapy for treating numerous diseases such as small-vessel vasculitis, erythema nodosum, vasculitis nodularis, Sweet's syndrome, tuberculosis and granulomatosis, and for iodized salt. At the same time, KI can be harmful. Iodine intake may increase the frequency of thyroiditis in humans, and may induce the occurrence of experimental thyroiditis (ET in animals. Investigations on an experimental model for the examination of thyroiditis in Wistar rats have clearly showed morphological changes in the rat thyroid evoked by KI administration. Objective The purpose of this study was to compare the effects of low and high doses of KI on the thyroid gland of Wistar rats and determine the effect on hormone status (T4, T3 and TSH in this rat strain. Methods Two groups of rats from the Wistar strain were treated with a low iodine dose (225 μg/g BW and with a high iodine dose (675 μg/g BW of KI solutions. Untreated nonimmunized animals served as controls. The solution was administrated daily intraperitoneally during the period of 26 consecutive days. Results Monitoring hormone status (TSH, T3 and T4 and morphological changes it was found that therapeutic doses of KI applied in treatment induced the occurrence of experimental thyroiditis (chronic destructive Hashimoto's thyroiditis in humans and cell necrosis in animals not carrying a genetic susceptibility. Significant inflammatory changes were observed in rats treated with a high iodine dose. Conclusion The early iodine induced cell necrosis and inflammation in the nonimmunized animals without genetic susceptibility is a new experimental model of thyroiditis. .

    Full Text Available Background: Pulmonary nocardiosis is a rare but a life-threatening infection caused by Nocardia spp. The diagnosis is often missed and delayed resulting in delay in appropriate treatment and thus higher mortality. Aim: In this study, we aim to evaluate the clinical spectrum and outcome of patients with pulmonary nocardiosis. Methods: A retrospective, 5-year (2009-2014 review of demographic profile, risk factors, clinical manifestations, imaging findings, treatment, and outcome of patients with pulmonary nocardiosis admitted to a tertiary care hospital. Results: The median age of the study subjects was 54 years (range, 16-76 and majority of them (75% were males. The risk factors for pulmonary nocardiosis identified in our study were long-term steroid use (55.6%, chronic lung disease (52.8%, diabetes (27.8%, and solid-organ transplantation (22.2%. All the patients were symptomatic, and the most common symptoms were cough (91.7%, fever (78%, and expectoration (72%. Almost two-third of the patients were initially misdiagnosed and the alternative diagnosis included pulmonary tuberculosis (n = 7, community-acquired pneumonia (n = 5, lung abscess (n = 4, invasive fungal infection (n = 3, lung cancer (n = 2, and Wegener′s granulomatosis (n = 2. The most common radiographic features were consolidation (77.8% and nodules (56%. The mortality rate for indoor patients was 33% despite treatment. Higher mortality rate was observed among those who had brain abscess (100.0%, HIV positivity (100%, need for mechanical ventilation (87.5%, solid-organ transplantation (50%, and elderly (age > 60 years patients (43%. Conclusion: The diagnosis of pulmonary nocardiosis is often missed and delayed resulting in delay in appropriate treatment and thus high mortality. A lower threshold for diagnosing pulmonary nocardiosis needs to be exercised, in chest symptomatic patients with underlying chronic lung diseases or systemic immunosuppression, for the early diagnosis, and

    Purpose: To present the surgical management of perforated corneal ulcer using PRECLUDE® Pericardial Membrane, composed of expanded polytetrafluoroethylene (e-PTFE; GORE-TEX®), as an alternative surgical procedure in patients at high risk of graft rejections and to evaluate side effects for a prolonged period. Patients and Methods: The study included all patients who were admitted to our department and underwent surgical repair of perforated corneal ulcer with the e-PTFE membrane between 2010 and 2015. In total, 8 patients (8 eyes) were enrolled. Medical records of all patients were retrospectively reviewed. The operation was performed under peribulbar anaesthesia. Non-absorbable, microporous, watertight 0.1 mm thick e-PTFE membrane was used to close the corneal ulcer. The membrane was cut to overlap the defect adequately and to achieve the desired tissue attachment without preparing the conjunctiva or superficial trephination of the cornea. The membrane was fixed to the healthy cornea with several non-absorbable sutures (Prolene® 10.0), in order to achieve the proper stress without wrinkling. Results: Five of 8 patients were treated for systemic immunological diseases. Sjögren's syndrome was diagnosed in 2 patients, granulomatosis with polyangiitis in one, vasculitis with a history of previous sclerokeratitis in one and systemic lupus erythematosus in one. In 2 patients, corneal perforation was observed as a complication of corneal infection and in one patient as a late complication of a severe chemical burn. Corneal perforations were successfully covered with e-PTFE membrane in all patients. E-PTFE membrane was well tolerated in all patients and the eye was always preserved. After 3 to 4 months, the membrane was removed in 7 patients. The underlying cornea was thin, firm, stable and vascularised. In one patient with Sjögren's syndrome, the e-PTFE membrane is still in place. Conclusion: Surgical management of perforated corneal ulcer using E-PTFE membrane

    Several classification schemes have been developed for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), with actual debate focusing on their clinical and prognostic performance. Sixty-two patients with renal biopsy-proven AAV from a single center in Mexico City diagnosed between 2004 and 2013 were analyzed and classified under clinical (granulomatosis with polyangiitis [GPA], microscopic polyangiitis [MPA], renal limited vasculitis [RLV]), serological (proteinase 3 anti-neutrophil cytoplasmic antibodies [PR3-ANCA], myeloperoxidase anti-neutrophil cytoplasmic antibodies [MPO-ANCA], ANCA negative), and histopathological (focal, crescenteric, mixed-type, sclerosing) categories. Clinical presentation parameters were compared at baseline between classification groups, and the predictive value of different classification categories for disease and renal remission, relapse, renal, and patient survival was analyzed. Serological classification predicted relapse rate (PR3-ANCA hazard ratio for relapse 2.93, 1.20-7.17, p = 0.019). There were no differences in disease or renal remission, renal, or patient survival between clinical and serological categories. Histopathological classification predicted response to therapy, with a poorer renal remission rate for sclerosing group and those with less than 25 % normal glomeruli; in addition, it adequately delimited 24-month glomerular filtration rate (eGFR) evolution, but it did not predict renal nor patient survival. On multivariate models, renal replacement therapy (RRT) requirement (HR 8.07, CI 1.75-37.4, p = 0.008) and proteinuria (HR 1.49, CI 1.03-2.14, p = 0.034) at presentation predicted renal survival, while age (HR 1.10, CI 1.01-1.21, p = 0.041) and infective events during the induction phase (HR 4.72, 1.01-22.1, p = 0.049) negatively influenced patient survival. At present, ANCA-based serological classification may predict AAV relapses, but neither clinical nor serological

    Additional risk minimisation measures (aRMMs) for medicinal products are necessary to address specific important safety issues which may not be practically achieved through routine risk management measures alone. The implementation and determination of effectiveness for aRMMs can be a challenge as it involves multiple stakeholders. It is therefore important to have concise objectives to avoid undue burden on patients, healthcare professionals and the healthcare system. The aim of this study was to examine how aRMMs are implemented and how effectiveness is assessed in the European Union (EU) using practical examples from Roche Products Limited in the United Kingdom (UK) (referred to as the 'Company'). Three centrally authorised products were selected from the Company's portfolio, each of which had aRMMs to address important safety concerns; specifically, teratogenicity, medication error and infections. The implementation of EU aRMMs, effectiveness checks and specific UK activities were analysed. Hard copy folders and electronic sites for Company aRMMs were used to assess process indicators. Periodic benefit-risk evaluation reports for specified time intervals and the Company safety database was used in checking safety outcomes for the selected products. For each product, the effectiveness of aRMMs was analysed based on specific process indicators and the subsequent safety outcomes. Literature searches were performed on scientific databases for the purposes of the broader study. The main process indicators in measuring effectiveness of Company aRMMs were distribution metrics for educational materials, assessment of awareness and clinical actions among healthcare professionals (HCPs). Case reports of pregnancy, medication errors and progressive multifocal leukoencephalopathy (PML) were the outcome indicators for Erivedge ® ▼, Kadcyla ® ▼ and MabThera ® (the latter specifically in autoimmune indications: rheumatoid arthritis, granulomatosis with polyangiitis and

    Churg-Strauss syndrome, recently renamed eosinophilic granulomatosis with polyangiitis (EGPA), is a rare form of systemic vasculitis, characterized by disseminated necrotizing vasculitis with extravascular granulomas occurring among patients with asthma and tissue eosinophilia. EGPA is classified as a small and medium-sized vessel vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA) and the hypereosinophilic syndrome. Typical clinical features include asthma, sinusitis, transient pulmonary infiltrates and neuropathy. Blood eosinophils are often >1500/µl or more than 10% on the differential leukocyte count. Blood eosinophils should always be tested in unexplained cardiac disorders, and may normalize even after low doses of corticosteroids. ANCA are positive in 40-60% of cases, mainly anti-myeloperoxidase. Heart involvement occurs in approximately 15-60% of EGPA patients, especially those who are ANCA negative. Any cardiac structure can be involved, and patients present with myocarditis, heart failure, pericarditis, arrhythmia, coronary arteritis, valvulopathy, intracavitary cardiac thrombosis. Although cardiovascular involvement is usually an early manifestation, it can also occur later in the course of the disease. A significant proportion of patients with cardiac involvement is asymptomatic. In the absence of symptoms and major ECG abnormalities, cardiac involvement may be detected in nearly 40% of the patients. All patients with EGPA should be studied not only with a detailed history of cardiac symptoms and ECG, but also with echocardiography; if abnormalities are detected, a cardiac magnetic resonance study should be performed. Coronary angiography and endomyocardial biopsy should be reserved to selected cases. Heart involvement carries a poor prognosis and causes 50% of the deaths of these patients. It is often insidious and underestimated. Optimal therapy is therefore important and based on high-dose corticosteroids plus immunosuppressive

    Full Text Available ANCA associated vasculitis (AAV comprises three syndromes with systemic vasculitis (Wegener’s granulomatosis (WG, Churg Strauss syndrome (CSS and icroscopic polyangiitis (MPA, which all involve small and medium sized vessels and are associated with antibodies against cytoplasmatic antibodies in neutrophils (ANCA. Polyarteritis nodosa (PAN is included in this review as it also affects medium sized vessels, and has many clinical findings in common with the AAV.Since the recognition of ANCA, increasing data have become available on the epidemiology of these vasculitidis. WG constitutes half of the AAV and its prevalence has increased from 30/million in the late 1980’s in the USA to 160/million in this century in northern Europe. The prevalence for the whole group of primary systemic vasculitides is now 300/million in Sweden. The annual incidence of WG increased from 6.0/million to 14/million during the 1990’s in Tromsø, but it is unknown if this is a true increase or the result of an increased awareness of the diagnosis. For the whole group of AAV, the annual incidence in most more recent studies is relatively constant over time and by geographical location, ranging from 13 to 21/million. Nonetheless there are interesting differences in the prevalence of specific vasculitis between different geographical areas, as well as for sub specificities of ANCA.There seems to be a South-North gradient for WG and PR3-ANCA with high figures reported from northern Europe and southern New Zealand. In European studies WG is 90% PR3-ANCA positive. MPA which is predominantly MPO-ANCA associated are more frequent in the Mediterranean countries and also has an increasing gradient towards east-Asia, as almost all AAV in China and Japan are diagnosed as MPA, predominantly MPO-ANCA positive.There are also some ethnic and gender differences. WG is most prevalent among Caucasians in the USA and in people with European ancestors in Paris and in New Zealand, less

    To describe the chest radiographic and CT findings of diffuse pulmonary hemorrhage. Two radiologists retrospectively analysed the chest radiographic and CT findings of six patients with diffuse pulmonary hemorrhage. Using open lung biopsy(n=3D2) and transbronchial lung biopsy or bronchoalveolar lavage(n=3D4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage. Underlying diseases were Wegener's granulomatosis(n=3D2), antiphospholipid antibody syndrome(n=3D2), Henoch-Schonlein purpura(n=3D1), and idopathic pulmonary hemosiderosis(n=3D1). In all patients, sequential chest radiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patinets, and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns of involvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CT scans. Chest radiographs showed multifocal patchy consolidation(n=3D6), ground-glass opacity(n=3D3), and multiple granular or nodular opacity(n=3D3). These lesions were intermingled in five patients, while in one there was consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonary abnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days, these had almost normalized. HRCT scans showed patchy consolidation(n=3D5), multiple patchy ground-glass opacity(n=3D5), or ill-defined air space nodules(n=3D4). These lesions were intermingled in five patients, and in one, ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intalobular reticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonal predominancy, and spared the apex of the lung and subpleural region were less affected.

Using open lung biopsy(n=3D2) and transbronchial lung biopsy or bronchoalveolar lavage(n=3D4), diagnosis was based on the presence of hemosiderin-laden macrophage or intra-alveolar hemorrhage. Underlying diseases were Wegener's granulomatosis(n=3D2), antiphospholipid antibody syndrome(n=3D2), Henoch-Schonlein purpura(n=3D1), and idopathic pulmonary hemosiderosis(n=3D1). In all patients, sequential chest radiographs, obtained during a one to six-month period, were available. HRCT scans were obtained in five patinets, and conventional CT scans in one. Follow-up HRCT scans were obtained in two. We also analyzed the patterns of involvement, distribution and sequential changes in the pulmonary abnormalities seen on chest radiographs and CT scans. Chest radiographs showed multifocal patchy consolidation(n=3D6), ground-glass opacity(n=3D3), and multiple granular or nodular opacity(n=3D3). These lesions were intermingled in five patients, while in one there was consolidation only. Sequential chest radiographs demonstrated the improvement of initial pulmonary abnormalities and appearance of new lesions elsewhere within 5-6 days, though within 7-25 (average, 13) days, these had almost normalized. HRCT scans showed patchy consolidation(n=3D5), multiple patchy ground-glass opacity(n=3D5), or ill-defined air space nodules(n=3D4). These lesions were intermingled in five patients, and in one, ground-glass opacity only was noted. In two patients there were interlobular septal thickening and intalobular reticular opacity. The distribution of these abnormalities was almost always bilateral, diffuse with no zonal predominancy, and spared the apex of the lung and subpleural region were less affected. Although chest radiographic and CT findings of diffuse pulmonary

    Key points Hypercalcaemia can occur under various pathological conditions, such as primary hyperparathyroidism, malignancy or granulomatosis, and it induces natriuresis and polyuria in various species via an unknown mechanism.A previous study demonstrated that hypercalcaemia induced by vitamin D in rats increased endothelin (ET)‐1 expression in the distal nephron, which suggests the involvement of the ET system in hypercalcaemia‐induced effects.In the present study, we demonstrate that, during vitamin D‐induced hypercalcaemia, the activation of ET system by increased ET‐1 is responsible for natriuresis but not for polyuria.Vitamin D‐treated hypercalcaemic mice showed a blunted response to amiloride, suggesting that epithelial sodium channel function is inhibited.We have identified an original pathway that specifically mediates the effects of vitamin D‐induced hypercalcaemia on sodium handling in the distal nephron without affecting water handling. Abstract Acute hypercalcaemia increases urinary sodium and water excretion; however, the underlying molecular mechanism remains unclear. Because vitamin D‐induced hypercalcaemia increases the renal expression of endothelin (ET)‐1, we hypothesized that ET‐1 mediates the effects of hypercalcaemia on renal sodium and water handling. Hypercalcaemia was induced in 8‐week‐old, parathyroid hormone‐supplemented, male mice by oral administration of dihydrotachysterol (DHT) for 3 days. DHT‐treated mice became hypercalcaemic and displayed increased urinary water and sodium excretion compared to controls. mRNA levels of ET‐1 and the transcription factors CCAAT‐enhancer binding protein β and δ were specifically increased in the distal convoluted tubule and downstream segments in DHT‐treated mice. To examine the role of the ET system in hypercalcaemia‐induced natriuresis and polyuria, mice were treated with the ET‐1 receptor antagonist macitentan, with or without DHT. Mice treated with both

    Diabetes insipidus (DI) is characterized by hypotonic polyuria greater than 3 liters/24 hours in adults and persisting even during water deprivation. It is mostly due to a defect in arginin-vasopressin (AVP) synthesis (central DI); other causes are: AVP resistance (nephrogenic DI), abnormal thirst regulation (primary polydipsia) or early destruction of AVP by placental enzymes (gestational DI). A thorough medical history is warranted to investigate nocturnal persistence of polyuria (night waking being a good sign of its organic nature) to specify the onset and duration of the trouble, the medication use and the potential hereditary nature of the disorder. The next step is based on weight and blood pressure measurements and especially the quantification of beverages and diuresis over a 24-hour cycle. Assessment of signs of dehydration, bladder distention, pituitary hormone hyper- or hyposecretion, tumor chiasmatic syndrome, granulomatosis and cancer is required. The diagnosis is based on biological assessment, pituitary magnetic resonance imaging (MRI) and results of a desmopressin test. In severe forms of DI, urine osmolality remains below 250 mOsmol/kg and serum sodium greater than 145 mmol/L. In partial forms of DI (urine osmolality between 250 and 750), the water deprivation test demonstrating the incapacity to obtain a maximal urine concentration is valuable, together with vasopressin or copeptin measurement. The pituitary MRI is done to investigate the lack of spontaneous hyperintensity signal in the posterior pituitary, which marks the absence of AVP and supports the diagnosis of central DI rather than primary polydipsia (although not absolute); it can also recognize lesions of the pituitary gland or pituitary stalk. Acquired central DI of sudden onset should suggest a craniopharyngioma or germinoma if it occurs before the age of 30 years, and metastasis after the age of 50 years. Fifteen to 20% of head trauma lead to hypopituitarism, including DI in 2% of

    Acute respiratory distress syndrome (ARDS) is an inflammatory lung disorder, and its pathological hallmark is diffuse alveolar damage (DAD). Given that open lung biopsy (OLB) can sometimes result in severe side effects, it is rarely performed in patients with ARDS. The aims of this study were to describe: (a) the rate of treatment change associated with the histological result; and (b) the incidence of side effects induced by OLB. A retrospective, single-center, descriptive observational study was carried out in Hospital Santa Clara (Bogotá, Colombia) from February 2007 to January 2014. Critically ill patients over 18 years of age, undergoing invasive mechanical ventilation, diagnosed with ARDS of unknown etiology, and with OLB performed at the bedside. ARDS was diagnosed according to the Berlin definition. DAD was defined by the presence of a hyaline membrane plus at least one of the following: intra-alveolar edema, alveolar type I cell necrosis, alveolar type II cell (cuboidal cells) proliferation progressively covering the denuded alveolar-capillary membrane, interstitial proliferation of fibroblasts and myofibroblasts, or organizing interstitial fibrosis. The rate of treatment change (RTC) was established according to whether the OLB pathology report resulted in: a) the prescription or discontinuation of an antimicrobial; b) the indication of new procedures; c) medical interconsultation; or d) limitation of therapeutic effort. Patients were followed-up until death or hospital discharge. This study was approved by the Ethics Committee. A total of 32 OLBs were performed during the study period; 17 were ruled out as they did not involve ARDS, and 15 were considered for further analysis. A histological diagnosis was reached in 14 of the 15 patients (12 DAD, one case of bronchiolitis obliterans organizing pneumonia and one case of Wegener's granulomatosis with alveolar hemorrhage). The RTC rate was 0.73. The most frequent intervention was discontinuation of

    Full Text Available Introduction: Vasculitis is an inflammation systems may be involved of blood vessels due to various origins. Vessels of the peripheral and/or central nervous. Vasculitis of the CNS is rare and occurs in the context of systemic diseases or as primary angiitis of the CNS. Epidemiology: The overall incidence of primary vasculitis is about 40/1,000,000 persons [excluding giant cell (temporal arteritis, GCA]. Its incidence increases with age. The incidence of GCA is much higher (around 200/1,000,000 persons in the age group[50 years. Clinical Presentation: Clinical and pathological presentation in CNS vasculitis represents a wide spectrum. Among others, headache, cranial nerve affections, encephalopathy, seizures, psychosis, myelitis, stroke, intracranial haemorrhage and aseptic meningoencephalitis are described. Primary and secondary vasculitides leading more frequently to CNS manifestations are discussed. Primary and secondary Vasculitides: Including Giant Cell (Temporal Arteritis , Takayasu arteritis, Polyarteritis nodosa, Primary angiitis of the CNS, Wegener’s granulomatosis, and Connective tissue diseases, such as systemic lupus erythematosus (SLE, scleroderma, rheumatoid arthritis, mixed connective disease and Sjögren syndrome, are systemic immune-mediated diseases that lead to multiple organ affections. Cerebral Vasculitis: Imaging and Differential Diagnosis: Vasculitides represent a heterogeneous group of inflammatory diseases that affect blood vessel walls of varying calibers (inflammatory vasculopathy. Since the devastating symptoms of CNS vasculitis are at least partially reversible, early diagnosis and appropriate treatment are important. In order to establish a differential diagnosis clinical features, disease progression, age of onset, blood results, as well as CSF examinations have to be taken into consideration. Neuroimaging techniques, such as MRI and DSA, play a central role in the diagnosis and disease monitoring .The diagnostic

    To identify and recombine a protein of the human dermal microvascular endothelial cell (HDMEC) that specifically reacts with anti-endothelial cell antibody (AECA) in the serum of patients with Behçet's disease (BD), and to evaluate the usefulness of this protein in BD. The proteomics technique, with 2-dimensional gel electrophoresis and matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectrometry, was used to identify and recombine HDMEC antigen. Western blotting and enzyme-linked immunosorbent assay (ELISA) of recombinant protein isolated by gene cloning were performed on serum from healthy controls, patients with BD, and patients with other rheumatic diseases (rheumatoid arthritis, systemic lupus erythematosus, and Wegener's granulomatosis). Eighteen of 40 BD patients had serum IgM antibody to HDMEC antigen. The purified protein that reacted with AECA in BD patient sera was found to be alpha-enolase by 2-dimensional gel electrophoresis followed by immunoblotting and MALDI-TOF mass spectrometry. Recombinant alpha-enolase protein was isolated and refined by gene cloning. On Western blots, AECA-positive IgM from the sera of patients with active BD reacted strongly with recombinant human alpha-enolase. BD patient sera positive for anti-alpha-enolase did not react with human gamma-enolase. On dot-blotting, reactivity to human alpha-enolase was detected only in the IgM-positive group. Fifteen of the 18 AECA-positive sera that were positive for the HDMEC antigen showed reactivity to recombinant alpha-enolase IgM antibody by ELISA. The alpha-enolase protein is the target protein of serum AECA in BD patients. This is the first report of the presence of IgM antibodies to alpha-enolase in endothelial cells from the serum of BD patients. Although further studies relating this protein to the pathogenesis of BD will be necessary, alpha-enolase and its antibody may prove useful in the development of new diagnostic and treatment modalities in BD.

    Assessment of cell proliferation in renal biopsy samples is a potentially promising analytical tool to evaluate disease activity. So far no information is available on the correlation between proliferative activity in different anatomic compartments of the kidney and clinical symptoms. To elucidate this issue, we examined renal biopsy specimens from 20 patients with systemic vasculitis (15 Wegener's granulomatosis, five microscopic polyangiitis), 20 patients with immunoglobulin (Ig) A nephropathy (IgAN), 13 patients with minimal-change disease (MCD), 11 patients with tubulointerstitial nephritis, and five patients with diabetes mellitus. The streptavidin-biotin-peroxidase complex technique was applied to autoclave-pretreated, formalin-fixed, paraffin-embedded tissue sections to label different cell types with the antibody MIB1 directed against the Ki-67 antigen. Proliferation index (PI) was estimated as the number of positively stained nuclei per glomerular cross-section or per square millimeter section area. The interstitial cells were discriminated by additional staining of Ki-67-processed samples with specific immune markers. In patients with vasculitis, PI was considerably elevated in the extracapillary glomerular compartment (0.86), in proximal tubules (6.24), and in the interstitium (8.62). High proliferative activity was also noted in interstitium (3.98) and proximal tubules (1.35) of patients with IgAN. Of particular interest was the increased interstitial proliferative activity (15.0) in diabetic patients. Resident renal cells, but not infiltrating cells, seemed to constitute the majority of the proliferating cell population in the interstitium. In systemic vasculitis, clinical disease activity was significantly correlated to endocapillary (r(s) = 0.58), extracapillary (r(s) = 0.67), proximal tubular (r(s) = 0.67), and interstitial PI (r(s) = 0.61). By multiple linear regression analysis, proximal tubular PI was correlated to the presence of hematuria

    The target sample size for clinical trials often necessitates a multicenter (center of excellence, CoE) approach with associated added complexity, cost, and regulatory requirements. Alternative recruitment strategies need to be tested against this standard model. The aim of our study was to test whether a Web-based direct recruitment approach (patient-centric, PC) using social marketing strategies provides a viable option to the CoE recruitment method. PC recruitment and Web-based informed consent was compared with CoE recruitment for a randomized controlled trial (RCT) of continuing versus stopping low-dose prednisone for maintenance of remission of patients with granulomatosis with polyangiitis (GPA). The PC approach was not as successful as the CoE approach. Enrollment of those confirmed eligible by their physician was 10 of 13 (77%) and 49 of 51 (96%) in the PC and CoE arms, respectively (P=.05). The two approaches were not significantly different in terms of eligibility with 34% of potential participants in the CoE found to be ineligible as compared with 22% in the PC arm (P=.11) nor in provider acceptance, 22% versus 26% (P=.78). There was no difference in the understanding of the trial as reflected in the knowledge surveys of individuals in the PC and CoE arms. PC recruitment was substantially less successful than that achieved by the CoE approach. However, the PC approach was good at confirming eligibility and was as acceptable to providers and as understandable to patients as the CoE approach. The PC approach should be evaluated in other clinical settings to get a better sense of its potential. ©Jeffrey Krischer, Peter F Cronholm, Cristina Burroughs, Carol A McAlear, Renee Borchin, Ebony Easley, Trocon Davis, Joyce Kullman, Simon Carette, Nader Khalidi, Curry Koening, Carol A Langford, Paul Monach, Larry Moreland, Christian Pagnoux, Ulrich Specks, Antoine G Sreih, Steven Ytterberg, Peter A Merkel, Vasculitis Clinical Research Consortium.
