    Abstract Background Pulmonary sarcoidosis involves an intense leukocyte infiltration of the lung with the formation of non-necrotizing granulomas. CC chemokines (chemokine (C-C motif) ligand 2 (CCL2)-CCL5) are chemoattractants of mononuclear cells and act through seven transmembrane G-coupled receptors. Previous studies have demonstrated conflicting results with regard to the associations of these chemokines with sarcoidosis. In an effort to clarify previous discrepancies, we performed the largest observational study to date of CC chemokines in bronchoalveolar lavage fluid (BALF) from patients with pulmonary sarcoidosis. Results BALF chemokine levels from 72 patients affected by pulmonary sarcoidosis were analyzed by enzyme-linked immunosorbent assay (ELISA) and compared to 8 healthy volunteers. BALF CCL3 and CCL4 levels from pulmonary sarcoidosis patients were not increased compared to controls. However, CCL2 and CCL5 levels were elevated, and subgroup analysis showed higher levels of both chemokines in all stages of pulmonary sarcoidosis. CCL2, CCL5, CC chemokine receptor type 1 (CCR1), CCR2 and CCR3 were expressed from mononuclear cells forming the lung granulomas, while CCR5 was only found on mast cells. Conclusions These data suggest that CCL2 and CCL5 are important mediators in recruiting CCR1, CCR2, and CCR3 expressing mononuclear cells as well as CCR5-expressing mast cells during all stages of pulmonary sarcoidosis.

    Objectives: To establish the particular advantages of High Resolution CT (HRCT) for the diagnosis of pulmonary sarcoidosis. Material and Methods: A series of fourteen patients, (4 men and 10 women; mean age 44,5 years) with thoracic sarcoidosis. All patients were studied using HRCT and diagnosis was confirmed for each case. Confidence intervals were obtained for different disease manifestations. Results: The most common findings were: lymph node enlargement (n=14 patients), pulmonary nodules (n=13), thickening of septa (n=6), peribronquial vascular thickening (n=5) pulmonary pseudo mass (n=5) and signs of fibrosis (n=4). The stage most commonly observed was stage II. It is worth noting that no cases of pleural effusion or cavitations of pulmonary lesions were observed. Conclusions: In this series, confidence interval overlapping for lymph node enlargement, single pulmonary nodules and septum thickening, allows to infer that their presence in a young adult, with few clinical symptoms, forces to rule out first the possibility of sarcoidosis.

    New approaches to define factors underlying the immunopathogenesis of pulmonary diseases including sarcoidosis and tuberculosis are needed to develop new treatments and biomarkers. Comparing the blood transcriptional response of tuberculosis to other similar pulmonary diseases will advance knowledge of disease pathways and help distinguish diseases with similar clinical presentations. To determine the factors underlying the immunopathogenesis of the granulomatous diseases, sarcoidosis and tuberculosis, by comparing the blood transcriptional responses in these and other pulmonary diseases. We compared whole blood genome-wide transcriptional profiles in pulmonary sarcoidosis, pulmonary tuberculosis, to community acquired pneumonia and primary lung cancer and healthy controls, before and after treatment, and in purified leucocyte populations. An Interferon-inducible neutrophil-driven blood transcriptional signature was present in both sarcoidosis and tuberculosis, with a higher abundance and expression in tuberculosis. Heterogeneity of the sarcoidosis signature correlated significantly with disease activity. Transcriptional profiles in pneumonia and lung cancer revealed an over-abundance of inflammatory transcripts. After successful treatment the transcriptional activity in tuberculosis and pneumonia patients was significantly reduced. However the glucocorticoid-responsive sarcoidosis patients showed a significant increase in transcriptional activity. 144-blood transcripts were able to distinguish tuberculosis from other lung diseases and controls. Tuberculosis and sarcoidosis revealed similar blood transcriptional profiles, dominated by interferon-inducible transcripts, while pneumonia and lung cancer showed distinct signatures, dominated by inflammatory genes. There were also significant differences between tuberculosis and sarcoidosis in the degree of their transcriptional activity, the heterogeneity of their profiles and their transcriptional response to treatment.

    Full Text Available Purpose. To investigate the clinical features and ocular manifestations of biopsy-proven pulmonary sarcoidosis in Korea. Methods. 55 patients diagnosed with pulmonary sarcoidosis by bronchoscopic or excisional biopsy were included. By retrospective clinical chart review, we investigated features of uveitis, ocular and systemic treatments, visual acuity, angiotensin-converting enzyme level, chest radiography, and pulmonary function tests. Clinical features were analyzed by presence of uveitis, site of biopsy, and first manifested sign of sarcoidosis. Results. The group with uveitis (n=39 presented with higher systemic (71.8% and immunosuppressive treatment rates (35.9% than the group without uveitis (31.3%, 0%, resp. (P=0.007, P=0.005, resp.. There were no significant differences in clinical features, including systemic treatment rate, by type of biopsy. Of 39 patients with uveitis, the group with ocular manifestation as a first sign of sarcoidosis showed higher systemic and immunosuppressive treatment rates (88.9%, 55.6% compared to the group with pulmonary manifestation as a first sign (57.1%, 19.0% (P=0.037, P=0.018, resp.. Conclusions. In patients with biopsy-proven pulmonary sarcoidosis, the presence of ocular involvement and uveitis as a first sign could be significant factors associated with higher systemic treatment rate, especially with immunosuppressive agents. Biopsy site determined by location and size had no influence on clinical features.

    Differentiating low-grade lymphoma from preexisting sarcoidosis is difficult because of their pathological similarity. This article describes a case of pulmonary mucosa-associated lymphoid tissue lymphoma associated with pulmonary sarcoidosis. The patient, a 45-year-old Japanese man, presented with a 10-year history of pulmonary sarcoidosis and 5-year history of ocular sarcoidosis with histologic findings. Because only the right S3 lung nodule had gradually enlarged, partial resection was performed. Pathological study revealed noncaseous epithelioid granulomas with lymphoplasmacytic proliferation but also marked lymphoid cell proliferation with lymphoepithelial lesion findings that differed from findings of typical sarcoid lesions. Our lymphoepithelial lesion evaluation via immunohistochemistry and analysis of Ig heavy-chain gene rearrangements with assessment of Propionibacterium acnes-specific antibody reactions allow us to report, for the first time, this case of pulmonary mucosa-associated lymphoid tissue lymphoma associated with pulmonary sarcoidosis in exactly the same location, which may be significant for differentiating these diseases and understanding their pathogenic association.

    Sarcoidosis is a multisystem disease characterised by the formation of granulomas within various organs, mainly the lungs. Several studies from different countries have been undertaken to investigate sarcoidosis with extrapulmonary involvement except from China. The objective of this study is to investigate a comparative clinical analysis in patients with pulmonary sarcoidosis with and without extrapulmonary involvement from China. Data from inpatients diagnosed with sarcoidosis at Shanghai Pulmonary Hospital (Shanghai, China) between January 2009 and December 2014 were retrospectively collected and analysed. Six hundred and thirty-six patients with biopsy-proven sarcoidosis were included in the study, including 378 isolated pulmonary sarcoidosis and 258 pulmonary sarcoidosis plus extrapulmonary involvement. Two hundred and fifty-eight (40.6%) patients with pulmonary sarcoidosis had extrapulmonary involvement. Extrapulmonary localisations were detected mostly in extrathoracic lymph nodes (n=147) and skin (n=86). Statistically significant differences were demonstrated between patients with pulmonary sarcoidosis plus extrapulmonary involvement and patients with isolated pulmonary sarcoidosis for fatigue (16.6%vs8.3%, PSACE) levels (79.0±46.9 IU/L vs 69.7±38.7 IU/L, PSACE levels and more deteriorating HRCT findings, to which clinicians should pay attention. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Patients with pulmonary and pulmonary plus extrapulmonary sarcoidosis differ in symptom severity and health status impairment. To date there is no information on differences in clinical and laboratory parameters between these phenotypes and limited information on extrapulmonary involvement in Czech sarcoidosis patients exists. We therefore compared clinical data (age, gender, organ involvement, lung function tests) and laboratory data (blood counts, bronchoalveolar fluid (BAL) cellular profile, serum levels of CRP, SACE, sIL-2R, neopterin) between patients with newly diagnosed pulmonary sarcoidosis (n=107) and those with pulmonary plus extrapulmonary sarcoidosis (n=54). Extrapulmonary sarcoidosis was diagnosed in 33% of patients, mostly affecting lymph nodes and skin and having hypercalciuria. There was no difference in the prevalence of extrapulmonary sarcoidosis between genders. Patients with extrapulmonary sarcoidosis were older and mostly non-smokers when compared to those with limited pulmonary form. X-ray Stage I and erythema nodosum were less frequent in extrapulmonary disease. Serum levels of CRP, SACE, sIL-2R and neopterin and BAL cellular profile did not differ between both phenotypes. We observed lower platelets, FEV1, VC, and BAL CD19+ in females with extrapulmonary involvement than in those with pulmonary disease. Affected lymph nodes, skin and hypercalciuria were the most common in sarcoidosis patients with extrapulmonary involvement. Pulmonary sarcoidosis did not differ in clinical and routine laboratory parameters from pulmonary plus extrapulmonary sarcoidosis. Observation of low platelets, VC, FEV1 and BAL CD19+ in females with extrapulmonary sarcoidosis needs further verification in larger cohort.

    Pulmonary sarcoidosis shows a remarkable heterogeneity of phenotypes ranging from bihilar lymphadenopathy to progressive fibrosis. Individual disease assessment is demanding and requires sensible, practical measures. We tested whether gas exchange measurements during exercise reflects disease activity and clinical course in sarcoidosis. In 149 patients with proven pulmonary sarcoidosis the alveolar-arterial oxygen pressure gradient (P(A-a)O(2)) during exercise was assessed and compared with chest X-ray typing, pulmonary function, single breath-diffusing capacity for carbon monoxide (DL(CO)), serological markers, cell composition of bronchoalveolar lavage fluid (BALF) and clinical course. Patients were categorized according to thresholds of P(A-a)O(2) during exercise. Chest X-ray typing, pulmonary function, DL(CO) and the need for immunosuppressive treatment differed between the disease categories based on P(A-a)O(2) during exercise (p 1 year), but not DL(CO). About 50% (n = 75) of the study population showed a normal spirometry. Even in this subgroup 23% had an impaired gas exchange during exercise, which correlated with chest X-ray types (p < 0.0001) and the need for immunosuppressive treatment (p < 0.005). Impaired gas exchange during exercise reflects disease activity and its extent and is associated with a prolonged need for immunosuppressive treatment during follow-up in patients with pulmonary sarcoidosis.

    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.

    We evaluated high resolution CT in 60 patients with histologically diagnosed pulmonary sarcoidosis and, also, studied the relationship between CT and findings in open lung biopsy specimens in 2 cases. The CT findings were as follows: (1) thickening of bronchial wall shadows (27 out of 60 cases, 45.0 %), (2) irregular enlargement of pulmonary vascular shadows (39 cases, 65.0 %), (3) small or large nodular shadows (24 cases, 40.0 %), (4) local volume loss (14 cases, 23.3 %), (5) slightly increased density of localized lung field areas (24 cases, 40.0 %), (6) pleural or subpleural involvement (27 cases, 45.0 %), (7) lymph node enlargement (59 cases, 98.3 %). X-ray CT in 7 patients revealed no evidence of lung field involvement in patients with histologicall confirmed epithelioid cell granuloma in transbronchial lung biopsy specimens. Lesions located within vessels or in the vascular wall, perivascular sheath or alveoli surrounding blood vessels might cause pulmonary vascular shadows to appear swollen on CT. In a comparative study, we found irregular dilatation of pulmonary vascular shadows corresponding to granulomas in the connective tissue sheath of blood vessels. Also, thickening of bronchial wall shadows corresponded to granulomas in and around the bronchial wall. From the point of histopathological view epithelioid cell granulomas in the bronchovascular sheath were most marked in sarcoidosis, and they apperaed on CT as an irregular enlargement of pulmonary vascular shadows and thickening of the bronchial wall. On the other hand, we reported that collapse of alveoli and fibrosis surrounding blood vessels could cause irregular enlargement of pulmonary vascular shadows on CT in idiopathic pulmonary fibrosis (IPF). Such shadows were seen on CT in both sarcoidosis and IPF but the mechanism of their appearance differed. (J.P.N.)

    Lung perfusion scintigraphy was performed in 23 patients with pulmonary sarcoidosis and in 11 normal volunteers. Bull's eye analysis was used to analyze regional pulmonary blood flow quantitatively. First, whole lung perfusion images were divided into three regions by three concentric circles. Then radial axes were projected from the center to define 36 x 10deg sectors. The counts for each sector were calculated and a Bull's eye image was displayed. The counts were compared with the lower limit of normal (mean -2SD), and as the indices of reduction in perfusion, extent score (ES) and severity score (SS) were calculated. ES and SS showed significant reduction in perfusion 16 patients (70%) with sarcoidosis. In stage II sarcoidosis, both ES and SS were significantly higher than in stage I sarcoidosis (p 67 Ga scintigraphy findings. In comparison with clinical data, ES had a positive correlation with serum angiotensin-converting enzyme activity (p + /CD8 + ratio (p<0.05). The Bull's eye analysis was considered useful for the quantitative evaluation of regional pulmonary blood flow in pulmonary sarcoidosis, and it was suggested that the mechanism of reduction in perfusion might result mainly in its alveolitis and angitis. Ventilation abnormality, which may happen prior to reduction in perfusion, may be an important factor of reduction in perfusion. (author)

    To assess CT findings of pulmonary sarcoidosis and correlate these with sACE level and PFT Between 1989 and 1995, 14 patients (4 men and 10 women, aged between 28 and 55 years) with histologically confirmed pulmonary sarcoidosis were consecutively selected. HRCT scans were performed in 12 patients and conventional CT scans in two. CT findings were reviewed by three radiologists, and were correlated with the index of disease activity based on sACE level and pulmonary function test. Pulmonary parenchymal abnormalities were seen in all patients;small nodules of less than 3mm in diameter were seen in eight. Other abnormalities were nodules of more than 3mm in diameter (n=7), confluent nodules (n=5), ground glass opacity (n=5), patchy areas of consolidation with air bronchogram (n=5), and architectural distortion (n=3). The upper lung zone was more frequently involved than the middle or lower zone. In ten patients, the paripheral interstitum was predominantly involved, while only three patients showed predominant peribronchovascular involvement. Lymphadenopathy was noted in 13. There was no correlation between sACE level, the results of a pulmonary function test and the extent of parenchymal involvement. HRCT is valuable for the identification, characterization, and determination of the extent to which parenchymal lung is involved in sarcoidosis. The extent of this involvement does not correlate with sACE level and pulmonary function test results

    Ocular manifestations of sarcoidosis in children are the second most common occurrence after hilar adenopathy and pulmonary abnormalities. We present the case history of a 14-year-old black boy who presented with redness of the left eye, blurred vision, and decreased visual acuity. He was subsequently diagnosed as having sarcoidosis. All patients with uveitis or ocular findings suggestive of sarcoidosis should have a through medical examination and a chest x-ray. Those suspected of or proven to have sarcoidosis should have a complete ophthalmological examination. Sarcoidosis in children appears to be more frequent than previously estimated.

    The 6-min walk test (6MWT) is a useful tool to assess prognosis and functional impairment in various pulmonary diseases. To evaluate functional capacity during various stages of pulmonary sarcoidosis and develop a scoring system clinical radiological physiological score (CRP) that can potentially be used to assess the functional status among patients with sarcoidosis. We performed a retrospective study on 26 patients diagnosed with pulmonary sarcoidosis from 2001 to 2007. All patients completed the 6MWT. The parameters assessed during the test included spirometry, arterial blood gas, 6-min walk distance (6MWD), Borg dyspnea score, and initial and end oxygen saturation. Females covered a significantly shorter distance than males (343 m (223-389) vs. 416.5 m (352-500); P < 0.0001). In addition, females had a significantly lower SpO 2 at the end of the 6MWT than males (90.5 (61-99) vs. 96 (75-98); P < 0.03). The 6MWD was inversely correlated with the final Borg score (r = ?0.603, P = 0.004) and the CRP score (r = -0.364, P = 0.047) and positively correlated with forced expiratory volume in 1 s (FEV 1 ) % (r 0.524, P = 0.006) and forced vital capacity (FVC) % (r = 0.407, P = 0.039). Female gender, FEV 1 %, final Borg score, FVC%, CRP score, and SpO 2 at the end of the 6MWT are associated with reduced 6MWD. It appears that Saudi patients diagnosed with sarcoidosis have a markedly reduced walking distance compared with other races. The effect of race and ethnicity and the utility of the CRP score as a potential marker to assess functional status require further exploration. (author)

    Sarcoidosis is still considered a rare multisystem disorder in Taiwan, and data on the disease course and outcome are limited. We analyzed the clinical manifestations, disease course and complications in Taiwanese patients with sarcoidosis. A retrospective cohort design was used. Fifty-six patients with sarcoidosis diagnosed between 1985 and 2004 were included. Their clinical features, laboratory findings at initial presentation, disease course, and complications were analyzed. Forty-three patients (76.8%) were female. The mean age at symptom onset was 47 years. The most common clinical symptoms were pulmonary (82.1%), cutaneous (23.2%), ophthalmic (19.6%), and articular (17.8%). Only two patients presented with Löfgren's syndrome. There was a seasonal variation in disease onset, with higher incidence in winter and early spring. No advanced pulmonary involvement was noted. Elevated levels of serum angiotensin converting enzyme (sACE) were found in 72.5% (29/40) of patients with active sarcoidosis, and significantly higher levels of sACE were found in patients with lung involvement (27.98+/-1.71 IU/L vs. 18.2+/-2.76 IU/L; psACE levels declined significantly in parallel with clinical remission (24.75+/-1.53 IU/L vs. 16.33+/-1.21 IU/L; psACE might be a marker of pulmonary involvement that is also useful in monitoring disease activity.

    Personality factors have shown to be related to mortality, morbidity, and psychological aspects in chronic disorders. Little is known about the effect of personality on disease severity in sarcoidosis and idiopathic pulmonary fibrosis (IPF). The aim of this study was to assess the prevalence of Type D personality and its relation with relevant clinical characteristics in sarcoidosis and IPF patients. The study included 441 sarcoidosis and 49 IPF patients from the outpatient clinic of the ild care team of the MUMC, the Netherlands. They completed the DS14 (Type D questionnaire), the fatigue assessment scale (FAS), the WHO quality of life-BREF (WHOQOL-BREF) and the Centre for Epidemiological Studies-Depression Scale (CES-D). Moreover, relevant clinical data were collected. The control group consisted of 3678 subjects from a general population. Type D personality was found in 25.6% of the sarcoidosis patients compared to 21% in the controls, but only in 18.8% of the IPF patients. No relation with disease severity was found in either of these disorders. Fatigue was a substantial problem in both populations. Depressive symptoms but not Type D personality predicted fatigue and poorer QOL in sarcoidosis and IPF. Prevalence of Type D personality is not higher in sarcoidosis and IPF patients than in the general population and does not explain QOL impairment. Depressive symptoms explain QOL impairment and fatigue substantially. Therefore, in the multidisciplinary management of sarcoidosis and IPF psychological screening and psychological counselling concerning adequate coping strategies should be incorporated.

    Severe thoracic sarcoidosis includes manifestations with significant clinical and functional impairment and a risk of mortality. Severe thoracic sarcoidosis can take on various clinical presentations and is associated with increased morbidity. The purpose of this article was to describe the CT findings in severe thoracic sarcoidosis and to explain some of their mechanisms. Subacute respiratory insufficiency is a rare and early complication due to a high profusion of pulmonary lesions. Chronic respiratory insufficiency due to pulmonary fibrosis is a frequent and late complication. Three main CT patterns are identified: bronchial distortion, honeycombing and linear opacities. CT can be helpful in diagnosing some mechanisms of central airway obstruction such as bronchial distortion due to pulmonary fibrosis or an extrinsic bronchial compression by enlarged lymph nodes. An intrinsic narrowing of the bronchial wall by endobronchial granulomatous lesions may be suggested by CT when it shows evidence of bronchial mural thickening. Pulmonary hypertension usually occurs in patients with end-stage pulmonary disease and is related to fibrotic destruction of the distal capillary bed and to the resultant chronic hypoxemia. Several other mechanisms may contribute to the development of pulmonary hypertension including extrinsic compression of major pulmonary arteries by enlarged lymph nodes and secondary pulmonary veno-occlusive disease. Aspergilloma colonization of a cavity is the main cause of hemoptysis in sarcoidosis. Other rare causes are bronchiesctasis, necrotizing bronchial aspergillosis, semi-invasive pulmonary aspergillosis, erosion of a pulmonary artery due to a necrotic sarcoidosis lesion, necrosis of parenchymal sarcoidosis lesions and specific endobronchial macroscopic lesions.

    To evaluate whether one can predict the course and prognosis of interstitial lung diseases from lung gallium-67 ( 67 Ga) uptake, we studied 31 subjects with sarcoidosis and 28 with idiopathic pulmonary fibrosis (IPF) retrospectively. We quantified the lung 67 Ga uptake using posterior scans by Line's method, and calculated a visual index (VI). The normal range of 67 Ga uptake was defined as less than 65 VI values, obtained from the 95 percent confidence interval of the control subjects. All subjects with stage I sarcoidosis, having only bilateral hilar lymphadenopathy (BHL) on chest X-ray, revealed normal lung 67 Ga uptake. Fifty percent of patients with stage II sarcoidosis, with both BHL and pulmonary involvement on chest X-ray, showed increased lung 67 Ga uptake. The patients with increased lung 67 Ga uptake showed decreased percent vital capacity and increased alveolar-arterial oxygen tension difference, but none of them showed clinical deterioration during the follow-up period of more than 6 months. Fifty-four percent of subjects with IPF sowed increased lung 67 Ga uptake. But there was no difference between the subgroups with normal and increased lung 67 Ga uptake with respect to the severity of dyspnea, percent vital capacity, arterial oxygen tension, or alveolar-arterial oxygen tension difference. There was also no difference between the two subgroups of IPF in the cumulative percent survival after either the onset of symptoms or the 67 Ga scintigram. We conclude that lung 67 Ga uptake was not able to predict the clinical course or the prognosis of patients with sarcoidosis and IPF. (author)

    To evaluate whether one can predict the course and prognosis of interstitial lung diseases from lung gallium-67 ({sup 67}Ga) uptake, we studied 31 subjects with sarcoidosis and 28 with idiopathic pulmonary fibrosis (IPF) retrospectively. We quantified the lung {sup 67}Ga uptake using posterior scans by Line's method, and calculated a visual index (VI). The normal range of {sup 67}Ga uptake was defined as less than 65 VI values, obtained from the 95 percent confidence interval of the control subjects. All subjects with stage I sarcoidosis, having only bilateral hilar lymphadenopathy (BHL) on chest X-ray, revealed normal lung {sup 67}Ga uptake. Fifty percent of patients with stage II sarcoidosis, with both BHL and pulmonary involvement on chest X-ray, showed increased lung {sup 67}Ga uptake. The patients with increased lung {sup 67}Ga uptake showed decreased percent vital capacity and increased alveolar-arterial oxygen tension difference, but none of them showed clinical deterioration during the follow-up period of more than 6 months. Fifty-four percent of subjects with IPF sowed increased lung {sup 67}Ga uptake. But there was no difference between the subgroups with normal and increased lung {sup 67}Ga uptake with respect to the severity of dyspnea, percent vital capacity, arterial oxygen tension, or alveolar-arterial oxygen tension difference. There was also no difference between the two subgroups of IPF in the cumulative percent survival after either the onset of symptoms or the {sup 67}Ga scintigram. We conclude that lung {sup 67}Ga uptake was not able to predict the clinical course or the prognosis of patients with sarcoidosis and IPF. (author).

    Full Text Available Abstract Background Littoral cell angioma (LCA is a rare vascular tumor of the spleen. Generally thought to be benign, additional cases of LCA with malignant features have been described. Thus, its malignant potential seems to vary and must be considered uncertain. The etiology remains unclear, but an immune dysregulation for the apparent association with malignancies of visceral organs or immune-mediated diseases has been proposed. Case Presentation We report a case of LCA in a 43-year old male patient who presented with a loss of appetite and intermittent upper abdominal pain. Computed tomography showed multiple hypoattenuating splenic lesions which were hyperechogenic on abdominal ultrasound. Lymphoma was presumed and splenectomy was performed. Pathological evaluation revealed LCA. Conclusions LCA is a rare, primary vascular neoplasm of the spleen that might etiologically be associated with immune dysregulation. In addition, it shows a striking association with synchronous or prior malignancies. With about one-third of the reported cases to date being co-existent with malignancies of visceral organs or immune-mediated diseases, this advocates for close follow-ups in all patients diagnosed with LCA. To our knowledge, this report is the first one of LCA associated with previous pulmonary sarcoidosis and hypothesizes a TNF-α related pathogenesis of this splenic tumor.

    Despite the relatively high cost and complicated procedures, Gallium-67 ( 67 Ga) scanning and bronchoalveolar lavage (BAL) are increasingly advocated as more sensitive indicators of disease activity in sarcoidosis than chest X-ray and serum angiotensin-converting enzyme activity (SACE). To evaluate the clinical usefulness of 67 Ga scanning and BAL, we followed 31 patients with pulmonary sarcoidosis, using these four parameters, at 9- to 24-month intervals over periods of 9 to 48 months. We obtained 68 complete evaluations. Close correlations were observed among chest X-ray, 67 Ga scanning, SACE, and the percent-age of lymphocytes in BAL fluid (p 67 Ga scanning and BAL are not necessarily indicated in the long-term management of pulmonary sarcoidosis.

    Purpose: The purpose of this study was to determine the feasibility of proton MRI of the lung in sarcoidosis patients and the agreement between the imaging appearance of pulmonary sarcoidosis on MRI and CT. Materials and methods: Chest CT scans and dedicated pulmonary MRI scans (including HASTE, VIBE, and TrueFISP sequences) were performed within 90 days of each other in 29 patients. The scans were scored for gross parenchymal opacification, reticulation, nodules, and masses using a 3-point lobar scale. Total and subset scores for corresponding MRI and CT scans were compared using the Spearman correlation test, Bland–Altman plots, and Cohen's quadratic-weighted kappa analysis. MRI scores were compared to CT by lobe and disease category, using percentage agreement, Spearman rank correlation, and Cohen's quadratic-weighted kappa. Results: The mean (±s.d.) time between MRI and CT scans was 33 ± 32 days. There was substantial correlation and agreement between total disease scoring on MRI and CT with a Spearman correlation coefficient of 0.774 (p < 0.0001) and a Cohen's weighted kappa score of 0.646. Correlation and agreement were highest for gross parenchymal opacification (0.695, 0.528) and reticulation (0.609, 0.445), and lowest in the setting of nodules (0.501, 0.305). Agreement testing was not performed for mass scores due to low prevalence. Upper lobe scoring on MRI and CT demonstrated greater agreement compared to the lower lobes (average difference in Cohen's weighted kappa score of 0.112). Conclusion: There is substantial correlation and agreement between MRI and CT in the scoring of pulmonary sarcoidosis, though MRI evaluation in the upper lobes may be more accurate than in the lower lobes

    Ethnicity is strongly associated with variable clinical presentation in sarcoidosis but the association between ethnicity and clinical characteristics has not previously been described in patients of Polynesian ancestry, Maori and Pacific Islander (PI). The objective of this study was to describe the clinical characteristics of sarcoidosis in Maori and PI patients and determine if those were different to European patients. A retrospective review of the medical records of 406 patients (69 Maori/PI) attending a specialist interstitial lung disease (ILD) clinic. The population (207 females, mean age at presentation: 36) reflected the current New Zealand census data (2013) with only people of Indian ethnicity over-represented. Parenchymal lung involvement was uncommon in Maori and PI patients (21% Scadding stage 2, 2% stage 3), and no patient had extensive pulmonary fibrosis (stage 4). Computed tomography (CT) patterns of sarcoid parenchymal lung involvement were less commonly reported for Maori/PI. There were no differences in respect of baseline lung function or requirement for treatment. Ocular and skin involvement occurred more frequently in Maori and PI (P = 0.0045, P = 0.03), and erythema nodosum was more common in Caucasians (P = 0.0008). People of Polynesian ancestry appear to have less pulmonary and more extra-pulmonary manifestations of sarcoidosis. This adds to our knowledge that sarcoidosis heterogeneity is influenced by ethnicity. © 2016 Asian Pacific Society of Respirology.

    Sarcoidosis, a multisystem granulomatous disorder, has historically been classified as Th1-driven disease. However, increasing data demonstrate a key role of Th17-cell plasticity in granuloma formation and maintenance. In Löfgren's syndrome (LS), an acute and distinct phenotype of sarcoidosis with a favorable outcome, differences in Th17-lineage cell subsets, cytokine expression and T-cell suppressive mechanisms may account for differences in clinical presentation as well as prognosis compared to non-LS sarcoidosis. In contrast with LS, up to 20% of non-LS sarcoidosis patients may progress to irreversible pulmonary fibrosis. In non-LS sarcoidosis patients, IFN-γ-producing Th17.1-cells appear to be more pathogenic and possibly linked to disease progression, while a broader range of cytokines is found in bronchoalveolar lavage fluid (BALF) in LS patients. Differences in Cytotoxic T-lymphocyte antigen 4 (CTLA-4) expression on Th17-cells and regulatory T-cells (Treg) could contribute to Th17-cell pathogenicity and consequently to either disease resolution or ongoing inflammation in sarcoidosis. Furthermore, several genes and SNPs are associated with disease susceptibility and outcome in sarcoidosis, the majority of which are involved in antigen presentation, T-cell activation or regulation of T-cell survival. Novel insights into the role of Th17-cells in the pathogenesis of both LS and non-LS sarcoidosis will unravel pathogenic and benign Th17-lineage cell function and drivers of Th17-cell plasticity. This will also help identify new treatment strategies for LS and non-LS sarcoidosis patients by altering Th17-cell activation, suppress conversion into more pathogenic subtypes, or influence cytokine signaling towards a beneficial signature of Th17-lineage cells. In this review, we summarize new insights into Th17-cell plasticity in the complex pathogenesis of sarcoidosis and connect these cells to the different disease phenotypes, discuss the role of genetic

    Respiratory epithelial clearance of 99m Tc-DTPA (RC-Tc-DTPA) and pulmonary function tests (PFT) were determined at intervals of 6 or 12 months in 37 untreated, nonsmoking patients with sarcoidosis over a period of 6 to 36 months. PFT included the measurements of total lung capacity (TLC), vital capacity (VC), FEV1, and diffusing capacity for carbon monoxide. No difference was found between the respiratory clearance of 113m In-DTPA (2.25 +/- 1.00%/min) and RC-Tc-DTPA (2.29 +/- 1.11%/min) in eight patients with pulmonary sarcoidosis. Pulmonary function decreased 15% or more in at least 2 function tests during 11 follow-up periods, but it remained stable during 47 follow-up periods. In patients whose lung function deteriorated, RC-Tc-DTPA increased to 3.51 +/- 1.55%/min; in contrast, in patients whose lung function remained stable, regardless of the initial values, RC-Tc-DTPA was normal (1.00 +/- 0.50%/min; p less than 0.001). In eight patients who were treated with corticosteroids, RC-Tc-DTPA decreased from 3.48 +/- 1.31%/min to 1.56 +/- 0.64%/min (p less than 0.001), and PFT improved. We conclude that in nonsmokers with pulmonary sarcoidosis, increased RC-Tc-DTPA is not related to dissociation of 99mTc from DTPA, RC-Tc-DTPA is increased when pulmonary function decreases, and, when increased, RC-Tc-DTPA decreases with corticosteroid therapy

    We analysed post enhanced chest CT scans of 5 pathologically proved sarcoidosis patients attempting to differentiate sarcoidosis from other diseases showing multiple lymph node enlargements. The distribution of intrathoracic lymphadenopathy was diffuse and bilateral in all cases. However the largest nodes were located at subcarnial, hilar and right paratracheal group (2R, 4R, 10R). Hilar node involvements were typically bilateral and symmetric. Anterior mediastinal and subcarinal regions, which were previously believed in unusual location, showed enlarged nodes in all cases. The appearances of the nodes were well-defined, homogenous soft tissue mass and the nodes did not show matted appearance. The pulmonary infiltration was bilateral and diffuse reticulonodular pattern. Our observations suggest that in cases of homogenous, discrete lymph node enlargements, particularly when subcarinal, bilateral hilar and right paratracheal node groups are involved, sarcoidosis should be included in the differential diagnosis

    Sarcoidosis is a multi-system, granulomatous disorder of unknown etiology that is associated with a variable prognosis and sometimes results in death. There are conflicting reports regarding the causes of death in patients with sarcoidosis. Forty-four consecutive patients with sarcoidosis who underwent an autopsy (35 patients) or died at Mayo Clinic (Rochester, MN, USA) over a 20-yr period, from January 1, 1994 to December 31, 2013 were analyzed. The median age at death was 63 years (range, 33-94 years) and there were 22 (50%) women. Sarcoidosis had not been clinically diagnosed in 16 (36%) patients before death. Fifteen deaths (34%) were related to sarcoidosis and included seven deaths (16%) from cardiac sarcoidosis and four deaths (9%) from progressive pulmonary sarcoidosis. Other sarcoidosis-related causes of death included advanced hepatic sarcoidosis (5%) and opportunistic infections (5%) related to immunosuppressive therapy for treating sarcoidosis. Among seven patients dying from cardiac sarcoidosis, three had been diagnosed with sarcoidosis during life and cardiac involvement was known in two of them. Six of seven deaths from cardiac sarcoidosis occurred in the autopsied cohort while all four deaths from pulmonary sarcoidosis occurred in those not autopsied. In the majority of patients dying with sarcoidosis the cause of death is unrelated to sarcoidosis. Cardiac involvement is the most common cause of sarcoidosis-related deaths in patients subjected to postmortem examination and was usually undiagnosed during life. The cause distribution of death in patients with sarcoidosis differed depending on whether autopsy was performed.

    Patients with sarcoidosis undergo spontaneous remission or may be effectively controlled with glucocorticoids alone in many cases. Progressive and refractory pulmonary sarcoidoisis constitute more than 10% of patients seen at specialized centers. Pulmonary fibrosis and associated complications, such as infections and pulmonary hypertension are leading causes of mortality. No universal definition of refractoriness exists, we therefore propose classifying patients as having refractory disease when the following criteria are fulfilled: (1) progressive disease despite at least 10 mg of prednisolone or equivalent for at least three months and need for additional disease-modifying anti-sarcoid drugs due to lack of efficacy, drug toxicity or intolerability and (2) treatment started for significant impairment of life due to progressive pulmonary symptoms. Both criteria should be fulfilled. Treatment options in addition to or instead of glucocorticoids for these patients include second- (methotrexate, azathioprine, leflunomide) and third-line agents (infliximab, adalimumab). Other immunmodulating agents can be used, but the evidence is very limited. Newer agents with anti-fibrotic properties, such as pirfenidone or nintedanib, might hold promise also for the pulmonary fibrosis seen in sarcoidosis. Treating physicians have to actively look for potentially treatable complications, such as pulmonary hypertension, cardiac disease or infections before patients should be classified as treatment-refractory. Ultimately, lung transplantation has to be considered as treatment option for patients not responding to medical therapy. In this review, we aim to propose a new definition of refractoriness, describe the associated clinical features and suggest the therapeutic approach.

    To investigate the relationships between the respiratory epithelial clearance of micronic aerosolized /sup 99m/Tc-DTPA (RC-DTPA) and pulmonary function, serum angiotensin-converting enzyme (SACE), and lymphocytic alveolitis in patients with sarcoidosis, RC-DTPA was measured in 49 nonsmokers with pulmonary sarcoidosis and 38 normal nonsmokers. Pulmonary involvement was evaluated on chest roentgenograms (type O = normal, type I = hilar adenopathies, type II = hilar adenopathies associated with parenchymal shadows, type III = parenchymal shadows without adenopathy) and by pulmonary function tests. Serum angiotensin-converting enzyme was determined, and a bronchoalveolar lavage was performed for alveolar lymphocyte differential counting (Ly%). RC-DTPA was increased (greater than or equal to 1.96%/min) in 12 of 31 patients with type II or III involvement but was normal in all 18 patients with type O or I involvement (p = 0.002). Patients with increased RC-DTPA had low FVC, TLC, FEV1, and resting Pao2 (p less than 0.05); resting and exercise AaPo2 were increased (p less than 0.05), but RC-DTPA correlated negatively with FEV1 (p less than 0.01), Pao2 at rest (p less than 0.005), and DLCO (p less than 0.05) and positively with resting and exercise AaPO2 (p less than 0.01). In patients with increased RC-DTPA (42 +/- 17%), Ly% did not differ from Ly% in patients with normal RC-DTPA (34 +/- 16%). SACE was increased in patients with increased RC-DTPA (56 +/- 26 U/ml versus 38 +/- 16 U/ml; p = 0.007) and correlated positively with RC-DTPA (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

    The findings of gallium imaging suggest that parotid abnormalities in sarcoidosis are common. Correlation with lung and mediastinal uptake suggests that this represents an early disease state and that it responds to steroid administration. That the findings after therapy do not simply represent suppression of the uptake mechanism for gallium is supported by objective improvement in pulmonary function as well as symptomatic relief. Salivary gland accumulation of gallium citrate occurred in one third of our control group patients--in those who had collagen disease and presumably either were alcoholic or had infectious parotitis. This may also be seen in lymphoma and after radiation therapy. Although the combination of salivary gland, pulmonary, and hilar concentration of gallium is not specific, in the appropriate clinical setting the pattern may be helpful in suggesting the correct diagnosis

    Sarcoidosis is a multisystem granulomatous disease of unknown origin with pulmonary and extrapulmonary manifestations. Worldwide it is most often diagnosed in the third and fourth decades and most often affects Swedish, Danish and black patients. The association between malignancy and sarcoidosis has not been conclusively proven. Cancer can eventually occur in patients who have an established diagnosis of sarcoidosis for example, in sarcoidosis-lymphoma syndrome. Sarcoidosis can also subsequently develop in an oncology patient. There are multiple obstacles to confirming epidemiologically the linkage between sarcoidosis and malignancy. Histological verification and clinical acumen are needed to avoid misdiagnosis. The 18 fluorodeoxyglucose (18-FDG) PET has failed to provide a non invasive diagnostic method to differentiate neoplasia from benign sarcoid lesions and tissue diagnosis is essential before commencing a new therapeutic intervention in patients with lymphoma.

    Full Text Available Sarcoidosis is a multisystem granulomatous disease, which is usually associated with the formation of noncaseating granulomas in affected tissues and organs. It is mostly present with bilateral hilar lymphadenopathy, pulmonary infiltration, ocular, and cutaneous lesions. Oral manifestations of this disease are relatively rare. The present case report shows a 40-year-old male with lesions in the soft tissue of oral cavity (buccal mucosa, gingiva, and palate and a diagnosis of sarcoidosis was established following hematological, biochemical and pulmonary function tests, chest radiograph, and histopathological investigation.

    Full Text Available Sarcoidosis is a multisystemic granulomatous disease of unknown etiology and it most commonly affects young adults. Childhood sarcoidosis is relatively rare; older children usually present a picture similar to that of adults, with frequent hilar lymphadenopathy and pulmonary infiltration. Early-onset (<4 years of age childhood sarcoidosis is a unique disease and has a different presentation. It is characterized by arthritis, uveitis, and cutaneous involvement. The prognosis of early-onset childhood sarcoidosis varies in different studies due to the rarity of the disease. The treatment of choice in systemic involvement of childhood sarcoidosis is corticosteroids. Methotrexate can also be considered in the long-term treatment due to its safety, effectiveness, and steroid-sparing effect in children.

    Sarcoidosis is a debilitating, inflammatory, multiorgan, granulomatous disease of unknown cause, commonly affecting the lung. In contrast to other chronic lung diseases such as interstitial pulmonary fibrosis or pulmonary arterial hypertension, there is so far no widely accepted or implemented animal model for this disease. This has hampered our insights into the etiology of sarcoidosis, the mechanisms of its pathogenesis, the identification of new biomarkers and diagnostic tools and, last not least, the development and implementation of novel treatment strategies. Over past years, however, a number of new animal models have been described that may provide useful tools to fill these critical knowledge gaps. In this review, we therefore outline the present status quo for animal models of sarcoidosis, comparing their pros and cons with respect to their ability to mimic the etiological, clinical and histological hallmarks of human disease and discuss their applicability for future research. Overall, the recent surge in animal models has markedly expanded our options for translational research; however, given the relative early stage of most animal models for sarcoidosis, appropriate replication of etiological and histological features of clinical disease, reproducibility and usefulness in terms of identification of new therapeutic targets and biomarkers, and testing of new treatments should be prioritized when considering the refinement of existing or the development of new models.

    To present the findings of sarcoidosis on female genital tract. Review. Department of Obstetric and Gynecology, Silesian Hospital Opava. Overview of published findings from case studies. Sarcoidosis is a multisystem granulomatous disorder of unclear cause. It typically involves the lymph nodes of mediastinum, predominantly billateral and/or pulmonary infiltrates. We find extrapulmonary involvement in 30-50% of cases. Sarcoidosis of the female reproductive system is a rare, it represent less than 1% cases of sarcoidosis. Lesions there may affect any organ, including the vulva, vagina, cervix, uterus, fallopian tube and ovary, but also for example placenta and breast. There is also recorded the incidence of multiple localization on female genitalia. Since sarcoidosis of this area is so rare, often proceeds asymptomatic and recognized only as an incidental finding, there are mention only the case histories in literature yet.Clinical symptoms may be non-specific, often imitating a tumor, or tend to be specific, depending on the localization of disability such as perineal pain, pain in the scar after the previous birth trauma, persistent pruritus, itching, irritation, dyspareunia, menstrual cycle disorders, menorrhagia, metrorrhagia, postmenopausal bleeding, amenorrhoe, abdominal pain, endometrial polypoid lesions, recurrent or persistent serometra or discharge. The diagnosis is made up of histologically - we are demonstrating noncaseating granulomas.The therapy is difficult, there are no available official guidelines. If the lesions are clinically silent, we can observed them because they may spontaneously disappear. If we are embarking on medical therapy, we start from a local application, and if this is unsuccessful then we approach the systemic administration. Corticosteroids are the drug of choice. If we diagnose the sarcoidosis of the female genital organs we must exclude systemic disease of sarcoidosis. The prognosis of disease is good.

    2017-01-01

    Full Text Available Sarcoidosis is an idiopathic disease that most commonly involves the lungs and is characterized by granulomatous inflammation. Bronchiectasis is one pulmonary manifestation of sarcoidosis, although it is almost always observed as traction bronchiectasis in the setting of fibrotic lung disease. A 50-year-old woman was evaluated for chronic cough and bronchiectasis with a small amount of peripheral upper lobe honeycombing and no significant pulmonary fibrosis or lymphadenopathy. After an extensive laboratory and imaging evaluation did not identify a cause of her bronchiectasis, bronchoscopy was performed to assess for primary ciliary dyskinesia and revealed a diffuse cobblestone appearance of the airway mucosa. Endobronchial biopsies and lymphocyte subset analysis of bronchoalveolar lavage fluid were consistent with a diagnosis of sarcoidosis. We believe endobronchial sarcoidosis should be included in the differential diagnosis of patients presenting with bronchiectasis.

    Objective: To discuss the noticeable problems in the radiological diagnosis of thoracic sarcoidosis through retrospective analysis of misdiagnosis. Methods: Imaging examinations of 32 misdiagnosed cases with thoracic sarcoidosis including chest radiography, CT, and their clinical data were reviewed. The final diagnosis was made by pathology (9 cases) and clinical therapy (23 cases). Results: Enlarged thoracic lymph nodes were detected in all cases. 23 of them presented mediastinal lymph node enlargement associated with bilateral hilar lymph node enlargement, 5 of them had mediastinal lymph node enlargement and unilateral hilar lymph node enlargement, and 4 of them had mediastinal lymph node enlargement without hilar lymph node enlargement. In these cases, 24 had pulmonary abnormalities. 19 of them showed multiple pulmonary nodes, 4 of them had patchy pulmonary shadows, and another 1 had pulmonary fibrosis. Pleural lesions included 2 hydrothorax and 1 multiple pleural nodes, and all of pleural lesions were associated with multiple pulmonary nodes. Conclusion: When the radiological findings of thoracic sarcoidosis are atypical, the diagnosis is difficult and must combine with the clinical findings, or the outcome of the treatment

    We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

  6. Increased serum YKL-40 in patients with pulmonary sarcoidosis--a potential marker of disease activity?

    YKL-40, a growth factor for fibroblasts and vascular endothelial cells, is secreted by macrophages and neutrophils. Elevated serum YKL-40 is found in patients with diseases characterized by inflammation, tissue remodelling and ongoing fibrosis. The aim was to evaluate whether macrophages and giant...... cells in the granulomatous sarcoid lesions of patients with pulmonary sarcoidosis produce YKL-40 and to determine whether serum YKL-40 in these patients were associated with disease activity....

    Full Text Available The present report describes a 60-year-old Caucasian woman who presented with progressive dyspnea, cough and wheeze. A computed tomography scan of the chest showed innumerable bilateral inflammatory pulmonary nodules with bronchovascular distribution and a mediastinal and hilar infiltrative process with calcified lymphadenopathy leading to narrowing of lobar bronchi and pulmonary arteries. An echocardiogram revealed pulmonary hypertension. Bronchoscopy showed left vocal cord paralysis and significant narrowing of the bilateral bronchi with mucosal thickening and multiple nodules. Transbronchial biopsy was compatible with sarcoidosis. Despite balloon angioplasty of the left lower lobe and pulmonary artery, and medical therapy with oral corticosteroids, her symptoms did not significantly improve. To the authors’ knowledge, the present report describes the first case of pulmonary sarcoidosis resulting in major airway, vascular and nerve compromise due to compressive lymphadenopathy and suspected concurrent granulomatous infiltration. Its presentation mimicked idiopathic mediastinal fibrosis.

    Cardiac involvement in sarcoidosis is reported in up to 30% of patients. Left ventricular involvement demonstrated by contrast-enhanced cardiac magnetic resonance has been well validated. We sought to determine the prevalence and distribution of right ventricular late gadolinium enhancement in patients diagnosed with pulmonary sarcoidosis. We prospectively evaluated 87 patients diagnosed with pulmonary sarcoidosis with contrast-enhanced cardiac magnetic resonance for right ventricular involvement. Pulmonary artery pressures were non-invasively evaluated with Doppler echocardiography. Patient characteristics were compared between the groups with and without right ventricular involvement, and right ventricular enhancement was correlated with pulmonary hypertension, ventricular mass, volume, and systolic function. Left ventricular late gadolinium enhancement was demonstrated in 30 patients (34%). Fourteen patients (16%) had right ventricular late gadolinium enhancement, with sole right ventricular enhancement in only two patients. The pattern of right ventricular enhancement consisted of right ventricular outflow tract enhancement in 1 patient, free wall enhancement in 8 patients, ventricular insertion point enhancement in 10 patients, and enhancement of the right side of the interventricular septum in 11 patients. Pulmonary arterial hypertension correlated with the presence of right ventricular enhancement (P Right ventricular enhancement correlated with systolic ventricular dysfunction (P Right ventricular enhancement was present in 16% of patients diagnosed with pulmonary sarcoidosis and in 48% of patients with left ventricular enhancement.

    Results of bronchoalveolar lavage (BAL), 67Ga scanning, and serum angiotensin-converting enzyme (SACE) assay are compared in the assessment of pulmonary involvement in ten cases of extrathoracic sarcoidosis. Standard clinical, radiologic, and pulmonary function tests detected no pulmonary changes in these patients, but BAL demonstrated an increased alveolar lymphocytosis in eight of ten cases. SACE levels were increased in two cases, and the thoracic gallium uptake was normal in all cases. BAL appears to be the best technique for diagnosing latent pulmonary involvement in extrathoracic sarcoidosis

    Subcutaneous sarcoidosis and sarcoid tenosynovitis are unusual manifestations of systemic sarcoidosis. We report two Japanese women with disseminated sarcoidosis presenting with subcutaneous and tenosynovial involvement demonstrated by computed tomography and magnetic resonance imaging. Sarcoidosis must be considered in the differential diagnosis of unexplained subcutaneous nodulosis or tenosynovitis in patients with or without a previous diagnosis of sarcoidosis.

    AIMS: To document the presence and extent of air trapping on high resolution computed tomography (HRCT) in patients with pulmonary sarcoidosis and correlate HRCT features with pulmonary function tests. METHODS: Twenty-one patients with pulmonary sarcoidosis underwent HRCT and pulmonary function assessment at presentation. Inspiratory and expiratory HRCT were assessed for the presence and extent of air trapping, ground-glass opacification, nodularity, septal thickening, bronchiectasis and parenchymal distortion. HRCT features were correlated with pulmonary function tests. RESULTS: Air trapping on expiratory HRCT was present in 20/21 (95%) patients. The extent of air trapping correlated with percentage predicted residual volume (RV)/total lung capacity (TLC) (r = 0.499;P < 0.05) and percentage predicted maximal mid-expiratory flow rate between 25 and 75% of the vital capacity (r = -0.54;P < 0.05). Ground-glass opacification was present in four of 21 (19%), nodularity in 18/21 (86%), septal thickening in 18/21 (86%), traction bronchiectasis in 14/21 (67%) and distortion in 12/21 (57%) of patients; there were no significant relationships between these CT features and pulmonary function results. CONCLUSION: Air trapping is a common feature in sarcoidosis and correlates with evidence of small airways disease on pulmonary function testing. Davies, C.W.H. (2000). Clinical Radiology 55, 217-221

    Sarcoidosis is a systemic granulomatous disorder of unknown aetiology with a wide spectrum of radiological appearances and almost invariably pulmonary involvement. Lung involvement accounts for most of the morbidity and much of the mortality associated with sarcoidosis. Imaging contributes significantly to the diagnosis and management of patients with sarcoidosis. In typical cases, chest radiography may be sufficient to establish the diagnosis with little margin of error and CT is not necessary. However, CT can play a critical role in several clinical settings: atypical clinical and/or radiographic findings; normal or near-normal chest radiograph but clinical suspicion of sarcoidosis; and detection of complications. Moreover, in many patients, CT findings are atypical and unfamiliar to most radiologists (e.g. sarcoidosis mimicking other lung diseases and vice versa), and in these cases histological confirmation of the diagnosis is recommended. CT is also useful in assessing disease extent and may help to discriminate between reversible and irreversible lung disease, thus providing critical prognostic information. This review concentrates on the more difficult imaging aspects of sarcoidosis, in particular differential diagnosis and disease complications. (orig.)

    The appearance of intracranial sarcoidosis on Gd-DTPA-enhanced MR imaging has not been previously reported. The authors have studied five patients with T1-and T2-weighted pre-GD and T1-weighted post-GD sequences. Images showed diffuse meningeal involvement suspected on the unenhanced scans in only one patient, enhancing extraaxial masses mimicking meningiomas, and enhancing and nonenhancing intraaxial lesions. In four of five patients, the diagnosis of intracranial sarcoidosis was suggested only after Gd-DTPA administration. The addition of Gd-DTPA greatly enhanced the sensitivity of MR imaging to the extraaxial and meningeal manifestations of central nervous system sarcoidosis

    Sarcoidosis is a systemic inflammatory disease characterized by the development of noncaseating granulomas in multiple organ systems. Many hematologic malignancies and solid tumors, including melanoma, have been associated with sarcoidosis. We describe the clinical and pathologic findings of a 54-year-old man with melanoma-associated sarcoidosis. In addition, we not only review the literature describing characteristics of other melanoma patients with sarcoidosis, but also the features of melanoma patients with antineoplastic therapy-associated sarcoidosis. Sarcoidosis has been described in 80 melanoma patients; sufficient information for analysis was provided in 39 of these individuals. In 43.6% of individuals (17 out of 39), sarcoidosis was directly associated with melanoma; in 56.4% of oncologic patients (22 out of 39), sarcoidosis was induced by antineoplastic therapy that had been administered for the treatment of their metastatic melanoma. The discovery of melanoma preceded the development of sarcoidosis in 12 of the 17 (70.5%) individuals who did not receive systemic treatment. Pulmonary and/or cutaneous manifestations of sarcoidosis were common among both groups of patients. Most patients did not require treatment for sarcoidosis. Melanoma patients—either following antineoplastic therapy or without systemic treatment—may be at an increased risk to develop sarcoidosis. In antineoplastic therapy naive melanoma patients, a common etiologic factor—such as exposure to ultraviolet light—may play a role in their developing melanoma and sarcoidosis.

    Various factors such as serum angiotensin-converting enzyme (sACE) activity, bronchoalveolar lavage (BAL) fluid lymphocyte percent, CD4/CD8 ratio, and shadows on chest radiograph have been identified as indexes of disease activity in patients with sarcoidosis. However, it remains to be confirmed whether these factors can predict clinical outcomes. To examine whether the interleukin-1 receptor antagonist (IL-1ra)/IL-1 beta ratio can predict the clinical course, we prospectively followed the clinical courses of 30 patients with pulmonary sarcoidosis 4 years after measurement of immunoreactive amounts of IL-1ra or IL-1 beta in the culture supernatants obtained from BAL fluid macrophages. Immunoreactive amounts of IL-1ra or IL-1 beta were measured using ELISA. Changes in pulmonary function, sACE activity, and shadows on chest radiographs during observation periods were evaluated as markers of changes in disease activity. We found that the patients whose shadows on chest radiographs showed improvement had a higher molar IL-1ra/IL-1 beta ratio than the patients whose shadows persistently remained 4 years after BAL examination (p sACE activity at the time of the last observation to sACE activity at the time of BAL (sACE(LAST)/sACE(BAL), p sACE(LAST)/sACE(BAL) ratio was significantly lower in patients whose shadows on chest radiographs decreased than in those whose shadows remained unchanged (p < 0.005). The IL-1ra/IL-1 beta ratio in the BAL fluid macrophage culture supernatants in patients with pulmonary sarcoidosis could be a useful marker in predicting the persistence of granulomatous lesions (chronicity).

    Full Text Available Background Sarcoidosis is a chronic inflammatory disease with a myriad of clinical manifestations. Treatment involves immunosuppression with corticosteroids or steroid-sparing agents. A proportion of patients does not respond to or are intolerant to therapy. Targeted immunotherapy with biologic agents has emerged as a novel approach with plausible mechanistic reasons to warrant study. Aims The aim of this review was to evaluate the evidence for the efficacy of biological therapy in sarcoidosis. Methods We conducted a systematic literature review and meta-analysis of all published randomised-controlled trials (RCT evaluating biological therapy in sarcoidosis, using MEDLINE and Embase databases, through to September 2017. The search terms included sarcoidosis, infliximab, adalimumab, etanercept, golimumab, certolizumab, rituximab, abatacept, tocilizumab, anakinra, ustekinumab, secukinumab. Only articles reporting RCTs were selected. Improvements in respiratory disease were assessed by changes in forced vital capacity (FVC by weighted mean difference (WMD. There were insufficient data on outcome measures in other organ systems to comparatively assess efficacy. Results The search identified 2,324 studies of which only 5 provided relevant and original data. This comprised a total of 364 patients, evaluating pulmonary, cutaneous and ocular sarcoidosis. One study in pulmonary disease and one study in cutaneous disease demonstrated improvements in the primary outcome. In pulmonary disease, meta-analysis of the treatment effect of anti-TNF therapy versus placebo on FVC revealed a WMD of 1.69 per cent (95 per cent confidence interval, 1.44–1.94. Conclusion There are insufficient data to suggest the long-term efficacy of anti-TNFα inhibitors in the treatment of sarcoidosis. This may be due to heterogeneity, small sample sizes and the lack of consistent reporting of outcome measures.

    Cardiac involvement in pulmonary sarcoidosis was found in a higher percentage than formerly reported, by careful observation. In a retrospective analysis of 1 236 patients with pulmonary sarcoidosis we found a possible cardiac involvement in 15.1%. In cases of pulmonary sarcoidosis or lymph node sarcoidosis combined with sarcoid lesions in other organs (liver, eyes, skin etc.) cardiac involvement is possible. Heart sarcoidosis was found in all roentgenographic stages and without sex difference. Patients with possible heart sarcoidosis suffer from dyspnoe , thoracical pain, heart discomfort, or angina pectoris in a higher part than without it. Enlargement of the heart and/or cardiac failure are signs of sarcoid involvement in patient with sarcoidosis, also in elderly patients. There are some difficulties in differential diagnosis of sarcoid cardiac involvement and ischaemic heart disease.

    Roentgenograms and gallium-67 scans and gallium-67 counts of BAL fluid samples, together with differential cell counts, have proved to be useful in assessing activity and lung involvement in sarcoidosis. In active pulmonary sarcoidosis gallium-67 scans are usually positive. Quantitation of gallium-67 uptake in lung scans, however, may be difficult. Because gallium-67 uptake and cell counts in BAL fluid may be correlated, we set out to investigate gallium-67 activity in BAL fluid recovered from patient of different groups. Sixteen patients with recently diagnosed and untreated sarcoidosis, nine patients with healthy lungs, and five patients with CFA were studied. Gallium-67 uptake of the lung, gallium-67 activity in the lavage fluid, SACE and LACE levels, and alpha 1-AT activity were measured. Significantly more gallium-67 activity was found in BAL fluid from sarcoidosis patients than in that from CFA patients (alpha = .001) or patients with healthy lungs (alpha = .001). Gallium-67 activity in BAL fluid could be well correlated with the number of lymphocytes in BAL fluid, but poorly with the number of macrophages. Subjects with increased levels of SACE or serum alpha 1-AT showed higher lavage gallium-67 activity than did normals, but no correlation could be established. High gallium-67 activity in lavage fluid may be correlated with acute sarcoidosis or physiological deterioration; low activity denotes change for the better. The results show that gallium-67 counts in BAL fluid reflects the intensity of gallium-67 uptake and thus of activity of pulmonary sarcoidosis

    Full Text Available Gallbladder granulomas are exceedingly rare, reported in association with tuberculosis or sarcoidosis. Here we report a case of gallbladder granulomatous cholecystitis occurring in the context of sarcoidosis. A 70-years old man presented with abdominal pain, nausea and vomiting. The medical history revealed sarcoidosis diagnosed more than 20-years previously. 2-years previously the patient showed renal lithiasis, hypercalcemia and, increased angiotensin converting enzyme. The imaging features suggested thoraco-abdominal sarcoidosis. Prednisone was given at 1.2 mg/kg/day initially, than decreased, being at 2.5 mg/day at present. The ultrasound examination showed gallbladder lithiasis. A cholecystectomy was performed. Microscopy showed subacute and chronic cholecystitis with several epithelioid and giant cell granulomas some of them perineural. In conclusion, we report a case of granulomatous cholecystitis occurring in the course of treated sarcoidosis. The perineural location of granulomas may give further insights into the pathogenesis of gallbladder dysmotility.

    Fifty-one sequential gallium citrate scans were performed in 22 patients with biopsy-proven sarcoidosis. A computer-assisted quantitative analysis of these scans was performed to obtain a gallium score. The changes in gallium score were correlated with changes in serum angiotensin converting enzyme (SACE) activity and objective changes in clinical status. There was a good concordance between changes in gallium score, SACE activity and clinical assessment in patients with sarcoidosis, and changes in gallium index were slightly superior to SACE index in assessing activity of sarcoidosis.

    Full Text Available Abstract Sarcoidosis is a multisystemic disorder of unknown cause characterized by the formation of immune granulomas in involved organs. It is an ubiquitous disease with incidence (varying according to age, sex, race and geographic origin estimated at around 16.5/100,000 in men and 19/100,000 in women. The lung and the lymphatic system are predominantly affected but virtually every organ may be involved. Other severe manifestations result from cardiac, neurological, ocular, kidney or laryngeal localizations. In most cases, sarcoidosis is revealed by persistent dry cough, eye or skin manifestations, peripheral lymph nodes, fatigue, weight loss, fever or night sweats, and erythema nodosum. Abnormal metabolism of vitamin D3 within granulomatous lesions and hypercalcemia are possible. Chest radiography is abnormal in about 90% of cases and shows lymphadenopathy and/or pulmonary infiltrates (without or with fibrosis, defining sarcoidosis stages from I to IV. The etiology remains unknown but the prevailing hypothesis is that various unidentified, likely poorly degradable antigens of either infectious or environmental origin could trigger an exaggerated immune reaction in genetically susceptible hosts. Diagnosis relies on compatible clinical and radiographic manifestations, evidence of non-caseating granulomas obtained by biopsy through tracheobronchial endoscopy or at other sites, and exclusion of all other granulomatous diseases. The evolution and severity of sarcoidosis are highly variable. Mortality is estimated at between 0.5–5%. In most benign cases (spontaneous resolution within 24–36 months, no treatment is required but a regular follow-up until recovery is necessary. In more serious cases, a medical treatment has to be prescribed either initially or at some point during follow-up according to clinical manifestations and their evolution. Systemic corticosteroids are the mainstay of treatment of sarcoidosis. The minimal duration of

    Gallium scan and serum angiotensin-converting enzyme assay (SACE) were compared in patients with sarcoidosis. The examination of 67 Ga scan, SACE determination, pulmonary function test, chest CT and chest X-ray in 24 cases with sarcoidosis were studied. The results revealed that 4 of 24 cases had obviously high uptake of 67 Ga exceeding hepatic activity (3+) in clinical active stage, 3 patients had resembling the Greek letter lambda, symmetrically located in bilateral hilar lymph nodes, and among them two had an uptake of 67 Ga in the bilateral lacrimal and parotid gland simulating 'Panda Face'. 8 of 20 cases with inactive sarcoidosis had an abnormal 67 Ga scan (1+). In those patients with normal SACE level but increased uptake of 67 Ga, active stage of disease was demonstrated and steroid therapy was indicated. Gallium scan is a valuable method for the staging of its activity and evaluation of the therapeutic effect in the follow-up patients with sarcoidosis

    2017-01-01

    Purposes: To describe the radiological findings of sarcoidosis or sarcoid-like reactions in cancer patients being monitored by positron emission computed tomography (PET/CT). Materials and methods: A retrospective analysis was performed on 18 PET/CT studies performed over 3 years in patients with lymphomas and solid tumours who presented with hypermetabolic hiliar-mediastinal adenopathies. The morphological pattern of these adenopathies, the distribution, and in some cases the association with pulmonary nodules, might suggest sarcoidosis as a differential diagnosis. Results: Oncological diseases corresponded to breast (4), prostate (3), ovary (2), and others (9). The adenopathies were classified in 7 of the 18 patients as benign after histological confirmation of sarcoidosis, anthracosis or sarcoid-like reaction. The evolutionary behaviour in 5 patients was compatible with benign lesions. The biopsy of 2 patients indicated secondary lesions and malignancy was confirmed by the evolution of the 4 remaining cases. There was a total of 12 (66%) benign lesions. Discussion: Sarcoidosis must be suspected in the presence of hypermetabolic hiliar-mediastinal adenopathies with a characteristic morphological pattern and pulmonary changes. However, biopsy is required to rule out oncological recurrence. The use of new PET/CT markers for differential diagnosis represents a challenge. Aminoacid synthesis tracers such as “1”8F-fluorothymidine (FLT) and “1”8F-fluoromethyltyrosine (FMT) are useful in the differentiation between malignancy and granulomatous diseases in oncologic patients. Conclusion: The differential diagnosis of sarcoidosis should be considered in the presence of bilateral symmetric mediastinal hilum lymphadenopathies. (authors) [es

  5. Management of sarcoidosis in clinical practice

    2016-06-01

    Full Text Available Sarcoidosis is a systemic disease of unknown cause with very diverse presentation, outcome, severity and need for treatments. While some presentations may be very typical, for many patients, the presentation is nonspecific, with shared associations with other diseases at times being by far more frequent or misleading, which can be a cause of significant delay and often several consultations before a diagnosis of sarcoidosis can be confirmed. This is particularly the case when pulmonary manifestations are in the forefront. The diagnosis relies on three well-known criteria. In clinical practice, these criteria are not easily implemented, particularly by physicians without expertise in sarcoidosis, which can lead to a risk of either under- or over-diagnosis. Qualifying the presentation according to sarcoidosis diagnosis is essential. However, it is often not easy to classify the presentation as typical versus compatible or compatible versus inconsistent. Further investigations are needed before any other hypothesis is to be considered. It is important to detect events and to determine whether or not they are indicative of a flare of sarcoidosis. Eventually, treatment needs to be related to the correct indications. The evaluation of the efficacy and safety of treatments is crucial. To address such issues, we present five emblematic cases that illustrate this.

    To find a pretreatment predictor of steroid responsiveness in pulmonary sarcoidosis the authors studied 21 patients before and after steroid treatment by clinical evaluation, pulmonary function tests, bronchoalveolar lavage (BAL), gallium-67 lung scan, and serum angiotensin-converting enzyme (SACE) level. Although clinical score, forced vital capacity (FVC), BAL percent lymphocytes (% lymphs), quantitated gallium-67 lung uptake, and SACE levels all improved with therapy, only the pretreatment BAL % lymphs correlated with the improvement in FVC (r = 0.47, p less than 0.05). Pretreatment BAL % lymphs of greater than or equal to 35% predicted improvement in FVC of 10/11 patients, whereas among 10 patients with BAL % lymphs less than 35%, 5 patients improved and 5 deteriorated. Clinical score, pulmonary function parameters, quantitated gallium-67 lung uptake, and SACE level used alone, in combination with BAL % lymphs or in combination with each other, did not improve this predictive value. The authors conclude that steroid therapy improves a number of clinical and laboratory parameters in sarcoidosis, but only the pretreatment BAL % lymphs are useful in predicting therapeutic responsiveness

    Sarcoidosis is a multisystem inflammatory disorder of unknown cause which can affect any organ system. Autosomal dominant lysozyme amyloidosis is a very rare form of hereditary amyloidosis. The Arg64 variant is extraordinarily rare with each family showing a particular pattern of organ involvement, however while Sicca syndrome, gastrointestinal involvement and renal failure are common, lymph node involvement is very rare. In this case report we describe the first reported case of sarcoidosis in association with hereditary lysozyme amyloidosis.

    Sarcoidosis is an inflammatory disorder that is characterized by the presence of noncaseating granulomas in tissues, involving many organs and tissues. Extra-pulmonary, especially muscular sarcoidosis is a rare condition. The most common location of the muscular sarcoidosis is known to be the proximal muscles of the extremities; however, there have been no cases of diffuse involvement of the chest and abdominal wall muscles. Here, we report a rare muscular sarcoidosis with infiltrative pattern in the chest and abdominal wall muscles and describe the MR imaging findings that were mistaken as lymphoma at initial diagnosis. Although our case did not show characteristic MR findings of muscular sarcoidosis, clinicians or radiologists who are aware of these imaging features can perform early systemic survey for sarcoidosis.

    Sarcoidosis is an inflammatory disorder that is characterized by the presence of noncaseating granulomas in tissues, involving many organs and tissues. Extra-pulmonary, especially muscular sarcoidosis is a rare condition. The most common location of the muscular sarcoidosis is known to be the proximal muscles of the extremities; however, there have been no cases of diffuse involvement of the chest and abdominal wall muscles. Here, we report a rare muscular sarcoidosis with infiltrative pattern in the chest and abdominal wall muscles and describe the MR imaging findings that were mistaken as lymphoma at initial diagnosis. Although our case did not show characteristic MR findings of muscular sarcoidosis, clinicians or radiologists who are aware of these imaging features can perform early systemic survey for sarcoidosis. Also muscle biopsy is very important to confirm the sarcoidosis and distinguish it from other tumors. (orig.)

    Sarcoidosis is a rare, systemic disease that is characterized by the formation of granulomas in various organs, including the skin. As the etiology remains unknown, the treatment of sarcoidosis is challenging. We present a 47-year-old female patient with progressive, multi-organ sarcoidosis who had a complete clinical improvement of the skin lesions, a moderate reduction in pulmonary opacities on chest X-ray, a marked subjective improvement in general status and pulmonary efficiency and a marked reduction in serum angiotensin-converting enzyme and soluble interleukin-2 receptor after 6 months of therapy with fumaric acid esters. The present case and similar reports in the literature highlight the probable efficacy of fumaric acid esters in the treatment of sarcoidosis and other non-infectious, granulomatous diseases. © 2014 S.

    Full Text Available Mycobacterium tuberculosis infection is a leading cause of infectious death worldwide. Gene-expression microarray studies profiling the blood transcriptional response of tuberculosis (TB patients have been undertaken in order to better understand the host immune response as well as to identify potential biomarkers of disease. To date most of these studies have focused on pulmonary TB patients with gene-expression profiles of extra-pulmonary TB patients yet to be compared to those of patients with pulmonary TB or sarcoidosis.A novel cohort of patients with extra-pulmonary TB and sarcoidosis was recruited and the transcriptional response of these patients compared to those with pulmonary TB using a variety of transcriptomic approaches including testing a previously defined 380 gene meta-signature of active TB.The 380 meta-signature broadly differentiated active TB from healthy controls in this new dataset consisting of pulmonary and extra-pulmonary TB. The top 15 genes from this meta-signature had a lower sensitivity for differentiating extra-pulmonary TB from healthy controls as compared to pulmonary TB. We found the blood transcriptional responses in pulmonary and extra-pulmonary TB to be heterogeneous and to reflect the extent of symptoms of disease.The transcriptional signature in extra-pulmonary TB demonstrated heterogeneity of gene expression reflective of symptom status, while the signature of pulmonary TB was distinct, based on a higher proportion of symptomatic individuals. These findings are of importance for the rational design and implementation of mRNA based TB diagnostics.

    In sarcoidosis, muscle involvement is common, but mostly asymptomatic. Currently, little is known about respiratory muscle and diaphragm involvement and function in patients with sarcoidosis. Reduced inspiratory muscle strength and/or a reduced diaphragm function may contribute to exertional dyspnea, fatigue and reduced health-related quality of life. Previous studies using volitional and non-volitional tests demonstrated a reduced inspiratory muscle strength in sarcoidosis compared to control subjects, and also showed that respiratory muscle function may even be significantly impaired in a subset of patients. Areas covered: This review examines the evidence on respiratory muscle involvement and its implications in sarcoidosis with emphasis on pathogenesis, diagnosis and treatment of respiratory muscle dysfunction. The presented evidence was identified by a literature search performed in PubMed and Medline for articles about respiratory and skeletal muscle function in sarcoidosis through to January 2018. Expert commentary: Respiratory muscle involvement in sarcoidosis is an underdiagnosed condition, which may have an important impact on dyspnea and health-related quality of life. Further studies are needed to understand the etiology, pathogenesis and extent of respiratory muscle involvement in sarcoidosis.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Current theory on the etiology of this disease involves participation of genetic factors and unknown antigens present in the patients' environment. The aim of the study was to evaluate the prevalence of different polymorphic forms of the ACE gene in healthy individuals and sarcoidosis patients, and to estimate the risk of sarcoidosis in carriers of different ACE genotypes living in rural and urban settings. The study group included 180 patients with pulmonary sarcoidosis. Assessment of the disease was based on clinical features, laboratory and imaging examinations, as well as bronchoscopy with bronchoalveolar lavage (BAL). ACE gene polymorphism was examined in DNA isolated from peripheral blood or BAL fluid (BALF) leukocytes. Incidence of sarcoidosis was not influenced by gender, age or place of residence of the patients. There were no differences in the frequency of particular genotypes in patients with sarcoidosis and in healthy individuals. The risk of disease did not depend on the ACE gene polymorphism. There were no differences in the frequencies of the different genotypes and alleles of the ACE gene in patients with sarcoidosis divided by gender, age and place of residence or by clinical manifestation of sarcoidosis. Our results do not support the previous concept which suggested a higher incidence of sarcoidosis in individuals living in rural areas and in carriers of selected ACE genotypes. It is possible that this is related to the changing environment of rural areas, increasing urbanization and pollution.

    In 66 patients the relationship between lung volumes and lung mechanics in pulmonary sarcoidosis was investigated. Lung volumes, static lung mechanics, lung resistance, dynamic lung mechanics and arterial blood gases at rest and during exercise were obtained. Fifteen functionally compromised patients received steroids during one year. They were re-investigated during the treatment and at a follow-up after an average of 7 years. In another 41 patients with newly diagnosed sarcoidosis, the kinetics of the lung clearance of 99m Tc-DTPA measured over 180 minutes was explored, and compared to kinetics in healthy smokers. The relationship between lung clearance and lung volumes, lung mechanics, arterial blood gases and disease activity assessed with serum angiotensin-converting enzyme and 67 Ga scintigraphy was studied. Reducing lung volumes and compliance, increased resistance and arterial oxygen tension were common. Vital capacity (VC), and changes of VC at follow-up, corresponded to the slope of the static elastic pressure/volume curve, and to the variation of it. Other static lung volumes reflected rather the position of the curve along the volume axis. Reduced VC also reflected obstruction. Forced expiratory volume in one second revealed to equal extent lung stiffness and obstruction. Lung mechanics showed abnormalities not always evident from spirometry.In 50% of the patients lung clearance of 99m Tc-DTPA disclosed an abnormally fast mono-exponential clearance or a bi-exponential clearance, which however differed from that in smokers. Lung clearance more readily detected abnormal function than did spirometry. Clearance did nor correlate with other investigations. 67 Ga lung activity was higher in patients with a pathologic lung clearance

    Our modification of a method for the absolute quantification of gallium-67 uptake in lungs with a scintillation camera and computer is described. The uptake of 67 Ga in lungs, expressed in percentage of administered radioactivity, was determined by the transmission-emission method. We proved theoretically and experimentally that a 67 Ga planar source could be replaced with a 57 Co planar source. The performance of lung perfusion scans allows a more accurate delineation of the regions of interest on gallium scans. The method was applied to control subjects (n=27) and to patients (n=114) suffering from biopsy-proven pulmonary sarcoidosis (28 with inactive and 86 with active disease). The obtained results were compared with chest X-ray findings, the percentage of lymphocytes in the bronchoalveolar fluid (BAF-ly%), and serum angiotensin-converting enzyme (SACE) values. The method seems suitable for the assessment of disease activity in sarcoidosis. It is more accurate in detecting parenchymal involvement in lung sarcoidosis than the commonly used X-ray criteria. No correlation was found between 67 Ga uptake and the BFA-ly% and SACE values. (orig.)

    This study was conducted to determine the role of Serum Angiotensin Converting Enzyme (SACE) as a marker in the differential diagnosis of pulmonary diseases and prognosis of sarcoidosis. A retrospective analysis of 113 medical records of patients at The Aga Khan University Hospital, with laboratory investigation for SACE was performed. Among 113 patients, 51 cases were found to have sarcoidosis, 44 of them had SACE levels greater than 52 IU/L (mean ACE 104.44). SACE levels were also found elevated in other clinical conditions like tuberculosis (mean 58.64 IU/L), but the enzyme level were less (p 0.04) than those found in sarcoidosis (mean (92.97 IU/L). SACE activity was found to be considerably lower in other chronic lung diseases such as, fibrosing alveolitis (mean 43.98 IU/L), interstitial lung disease (mean 42.11 IU/L) and chronic obstructive lung disease (mean 40.85 IU/L). Twenty patients of sarcoidosis, who received steroid treatment subsequently showed a decline in the SACE levels. SACE is a useful marker in differential diagnosis as 37.2% cases of sarcoidosis compared to only 9.09% of tuberculosis had SACE levels greater than 100 IU/L. In addition, our data also suggest that serum ACE is useful for the diagnosis as well as monitoring prognosis in sarcoidosis.

  18. Ocular sarcoidosis masked by positive IgM for toxoplasmosis

    Full Text Available ABSTRACT We report a case of ocular sarcoidosis with positive immunoglobulin (Ig M and IgG serology for toxoplasmosis. The patient was a young female with red painful eyes, bilateral eyelid edema, and panuveitis with periphlebitis. In laboratory testing, she was IgM and IgG positive for toxoplasmosis and anergic in the tuberculin test. Topical treatment for anterior uveitis and oral antibiotics for toxoplasmosis were started, without improvement. Orbit tomography showed increased lacrimal glands bilaterally, and chest X-ray radiographic findings were consistent with pulmonary sarcoidosis, which supported the presumed ocular sarcoidosis diagnosis. The patient was treated with oral prednisone and methotrexate without antibiotics. She showed clinical and vision improvement without recurrences during the 1-year follow-up. Ocular sarcoidosis is an important differential diagnosis requiring careful anamnesis and ophthalmological examinations. Ancillary tests, such as X-ray radiography, tomography, and clinical and laboratory evaluations may help rule out other causes. Treatment mainly consists of corticosteroids and immunosuppression.

    Cellular characteristics of BAL were investigated in 18 patients with proved extrathoracic sarcoidosis (that is, sarcoidosis that affected the skin, eyes, parotid glands, stomach, nose, kidneys, or meninges) without clinical or radiological mediastinopulmonary involvement. Computed tomography of the thorax was performed on five patients: four patients were normal, and one had enlarged lymph nodes (these enlargements were not detectable on the patient's chest roentgenogram). The results of pulmonary function tests were normal in all patients. The total BAL cell count did not differ significantly between controls and patients. Abnormal percentages of alveolar lymphocytes (from 18 to 87%) were noted in 15 out of 18 patients. SACE levels were normal in 15 patients. No pulmonary gallium uptake was detected. The chemiluminescence of AM's, whether spontaneous or PMA induced, was increased in five out of seven patients. The percentages of T3+ lymphocytes in sarcoidosis patients did not significantly differ from those in controls. The T4+:T8+ ratio was normal in four patients and slightly increased in one. Follow-up of patients showed that alveolar lymphocytosis is as lasting as extrathoracic involvement. Our data demonstrate increased percentages of lymphocytes and activated AM's in the BAL of patients with extrathoracic sarcoidosis. This may be due to the initial involvement of the respiratory tract in extrathoracic sarcoidosis or to the diffusion of activated macrophages and lymphocytes from an extrathoracic site into the lung

    The isoprenoid pathway produces three key metabolites: endogenous digoxin (membrane sodium-potassium ATPase inhibitor, immunomodulator and regulator of neurotransmitter/amino acid transport), dolichol (regulates N-glycosylation of proteins) and ubiquinone (free radical scavenger). The role of the isoprenoid pathway in the pathogenesis of sarcoidosis in relation to hemispheric dominance was studied. The isoprenoid pathway-related cascade was assessed in patients with systemic sarcoidosis with pulmonary involvement. The pathway was also assessed in patients with right hemispheric, left hemispheric and bihemispheric dominance for comparison to find out the role of hemispheric dominance in the pathogenesis of sarcoidosis. In patients with sarcoidosis there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in the cholesterol:phospholipid ratio and a reduction in the glycoconjugate level of red blood cell (RBC) membrane in this group of patients. The same biochemical patterns were obtained in individuals with right hemispheric dominance. In individuals with left hemispheric dominance the patterns were reversed. Endogenous digoxin, by activating the calcineurin signal transduction pathway of T cells, can contribute to immune activation in sarcoidosis. An altered glycoconjugate metabolism can lead to the generation of endogenous self-glycoprotein antigens in the lung as well as other tissues. Increased free radical generation can also lead to immune activation. The role of a dysfunctional isoprenoid pathway and endogenous digoxin in the pathogenesis of sarcoidosis in relation to right hemispheric chemical dominance is discussed. All the patients with sarcoidosis were right-handed/left hemispheric dominant according to the dichotic listening test, but their biochemical patterns

    Full Text Available Abstract Childhood sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. In the pediatric series reported from the southeastern United States, sarcoidosis had a higher incidence among African Americans. Most reported childhood cases have occurred in patients aged 13–15 years. Macrophages bearing an increased expression of major histocompatibility class (MHC II molecules most likely initiate the inflammatory response of sarcoidosis by presenting an unidentified antigen to CD4+ Th (helper-inducer lymphocytes. A persistent, poorly degradable antigen driven cell-mediated immune response leads to a cytokine cascade, to granuloma formation, and eventually to fibrosis. Frequently observed immunologic features include depression of cutaneous delayed-type hypersensitivity and a heightened helper T cell type 1 (Th1 immune response at sites of disease. Circulating immune complexes, along with signs of B cell hyperactivity, may also be found. The clinical presentation can vary greatly depending upon the organs involved and age of the patient. Two distinct forms of sarcoidosis exist in children. Older children usually present with a multisystem disease similar to the adult manifestations, with frequent hilar lymphadenopathy and pulmonary infiltrations. Early-onset sarcoidosis is a unique form of the disease characterized by the triad of rash, uveitis, and arthritis in children presenting before four years of age. The diagnosis of sarcoidosis is confirmed by demonstrating a typical noncaseating granuloma on a biopsy specimen. Other granulmatous diseases should be reasonably excluded. The current therapy of choice for sarcoidosis in children with multisystem involvement is oral corticosteroids. Methotrexate given orally in low doses has been effective, safe and steroid sparing in some patients. Alternative immunosuppressive agents, such as azathioprine, cyclophosphamide, chlorambucil, and cyclosporine, have been tried in adult cases

    Among the various renal manifestations of sarcoidosis, granulomatous inflammation confined to the tubulointerstitial compartment is the most commonly reported finding. We present the case of a 66-year-old man with acute kidney injury, hypercalcemia, mild restrictive pulmonary disease, and neurologic signs of parietal lobe dysfunction. Kidney biopsy showed diffuse interstitial inflammation with noncaseating granulomas that exhibited the unusual feature of infiltrating the walls of small arteries with destruction of the elastic lamina, consistent with granulomatous vasculitis. The findings of granulomatous interstitial nephritis on kidney biopsy, hypercalcemia, and possible cerebral and pulmonary involvement in the absence of other infectious, drug-induced, or autoimmune causes of granulomatous disease established the diagnosis of sarcoidosis. Pulse methylprednisolone followed by maintenance prednisone therapy led to improvement in kidney function, hypercalcemia, and neurologic symptoms. Vasculocentric granulomatous interstitial nephritis with granulomatous vasculitis is a rare and under-recognized manifestation of renal sarcoidosis. Copyright © 2012 National Kidney Foundation, Inc.

    Sarcoidosis is uncommon not rare disease in western nations. But in Korea there is no case report of this disease yet. Diagnosis of sarcoidosis is considered established when typical radiological findings and consistent clinical features are present with biopsy evidence of noncaseating epitheliod tubercles or a positive Kveim test. The patient is 40 year old Korean female with complaint of visual disturbance. Chest radiograms show bilateral hilar and paratracheal lymphadenopathy and pulmonary parenchymal involvement. Biopsy of nodule at left knee shows non-caseating tuberculoma. Tuberculin skin-test with PPD of 1:2,000 is negative. Sputum smear for A. F. B. are negative for 4 times. Kveim test is positive. We think that more cases will be found in Korea, if we consider the possibility of sarcoidosis when see a chest radiogram with lymphadenopathy with or without parenchymal change

    Serum angiotensin-converting enzyme (ACE) is elevated in many patients with pulmonary sarcoidosis and has been proposed as a measure of disease activity. The present study was designed to evaluate the possible relationship between serum ACE and direct measures of the intensity of the alveolitis of pulmonary sarcoidosis as measured by bronchoalveolar lavage and gallium-67 ( 67 Ga) scans. To accomplish this, 64 measurements of serum ACE, lavage T lymphocytes, and lung uptake of 67 Ga were performed in 41 patients with biopsy-proven sarcoidosis. Elevations of serum ACE were found on at least one occasion in 17 patients (41%). However, serum ACE was found to be a poor predictor of the intensity of alveolitis in sarcoidosis as assessed by the quantitation of bronchoalveolar lavage cells that were T lymphocytes and by 67 Ga scanning. Elevated serum ACE did not predict which patients would have elevated proportions of lavage T lymphocytes, which patients would demonstrate increased pulmonary uptake of 67 Ga, or which patients would have high-intensity alveolitis as defined by a combination of these criteria. These observations suggest that while serum ACE may be useful in diagnosing sarcoidosis, it does not reflect accurately the intensity of the alveolitis of the pulmonary component of this disease.

    Full Text Available OBJECTIVE: To determine the frequency of and the factors related to delayed diagnosis of sarcoidosis in Brazil. METHODS: We evaluated patients with a biopsy-proven diagnosis of sarcoidosis, using a questionnaire that addressed the following: time since symptom onset and since the first medical visit; and the number and specialty of the physicians visited. We divided the patients by the timeliness of the diagnosis-timely (< 6 months and delayed (≥ 6 months-comparing the two groups in terms of systemic and pulmonary symptoms; extrathoracic involvement; spirometric data; radiological staging; level of education; income; and tuberculosis (diagnosis and treatment. RESULTS: We evaluated 100 patients. The median number of physicians consulted was 3 (range, 1-14. In 11 cases, sarcoidosis was diagnosed at the first visit. In 54, the first physician seen was a general practitioner. The diagnosis of sarcoidosis was timely in 41 patients and delayed in 59. The groups did not differ in terms of gender; race; type of health insurance; level of education; income; respiratory/systemic symptoms; extrathoracic involvement; and radiological staging. In the delayed diagnosis group, FVC was lower (80.3 ± 20.4% vs. 90.5 ± 17.1%; p = 0.010, as was FEV1 (77.3 ± 19.9% vs. 86.4 ± 19.5%; p = 0.024, misdiagnosis with and treatment for tuberculosis (≥ 3 months also being more common (24% vs. 7%, p = 0.032, and 20% vs. 0%; p = 0.002, respectively. CONCLUSIONS: The diagnosis of sarcoidosis is often delayed, even when the imaging is suggestive of sarcoidosis. Delayed diagnosis is associated with impaired lung function at the time of diagnosis. Many sarcoidosis patients are misdiagnosed with and treated for tuberculosis.

    A 30-year-old man who incidentally fractured his right olecranon and other multiple phalanges was admitted to our hospital. He had a 2-year history of uveitis and bilateral hilar lymphadenopathy (BHL), and pulmonary sarcoidosis was diagnosed from transbronchial lung biopsy. Right elbow arthrodesis was performed, and biopsied specimens showed non-caseating epithelioid cell granuloma, suggesting osseous sarcoidosis. He was discharged uneventfully without further treatment, but BHL had progressed with the appearance of lung parenchymal lesions 3 months later. At that time, involvement of other organs was also noted on Gallium-67 scintigraphy, showing accumulations in BHL, axillary and inguinal lymph nodes, enlarged liver and spleen and subcutaneous areas. After initiation of steroid therapy, multiple organ involvement improved, and no further bone involvement has been recognised to date. Osseous sarcoidosis complicated by bone fracture is an extremely rare presentation, but should be considered in patients with sarcoidosis, especially when multiple organs are involved.

    Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility. Sarcoidosis should therefore be an important consideration for the otolaryngologist's differential diagnosis of true vocal fold immobility. Copyright © 2018 The Voice Foundation.

    Full Text Available Sarcoidosis is a systemic disease of unknown etiology in which infectious agents have been implicated, inorganic powders or organic substances, characterized by the presence of necrotizing granulomatous inflammation with no accumulation of CD4 + lymphocytes and monocytes in the affected tissues. It is presented the case of a patient who went to the General University Hospital Dr. Gustavo Aldereguía Lima of Cienfuegos reporting dry cough, fever, chest tightness and slight weight loss three of three months evolution which did not improve despite receiving treatment in his health area. After several studies it was diagnosed a proliferative pulmonary sarcoidosis, systemic granulomatous disease whose etiology remains anonymous. Biopsy remains the basis for definitive diagnosis. As this is a difficult entity to explain and understand, besides being scarcely diagnosed in our area, it is decided to present that clinical case.

    Sarcoidosis and tuberculosis closely resemble each other and Mycobacterium tuberculosis has been implicated as a causative agent for sarcoidosis. Herein we explore the socio-demographic features of patients with sarcoidosis vis-a-vis tuberculosis. In a prospective case-control design, we studied hundred patients each of newly diagnosed sarcoidosis, bacteriologically confirmed pulmonary tuberculosis and healthy controls. Socio-demographic profile was recorded on a standardized questionnaire. Information about tobacco smoking, exposure to environmental tobacco smoke (ETS) and cooking fuels was also collected. Various parameters were compared among the three groups. Compared to tuberculosis, patients with sarcoidosis were elder, had better body mass index (BMI), higher urban residence (OR 2.19, 95% CI: 1.02-4.69), were better educated (ORs 8.50 to 74.25 for different categories), had higher per capita income (OR 13.33; 95% CI: 6.79-26.19) and belonged to better overall socio-economic status (SES) (ORs 8.57-195.0 for different categories). All these differences were also significant when sarcoidosis patients were compared to healthy controls albeit to a lesser degree. Tobacco smoking, ETS exposure and use of fossil/biomass fuels for cooking were more commonly seen in TB patients. In the multivariate analysis, as compared to TB or controls, sarcoidosis patients had higher odds for a better SES after adjusting for age, gender, BMI, religion, smoking, ETS exposure and cooking fuel. Patients with sarcoidosis are likely to be better educated and more affluent compared to those with tuberculosis and healthy controls and this can be useful in clinical differential diagnosis of the two conditions in populations with high prevalence of TB.

    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

  16. Upregulation of neurokinin-1 receptor expression in the lungs of patients with sarcoidosis.

    2012-02-03

    Substance P (SP) is a proinflammatory neuropeptide that is secreted by sensory nerves and inflammatory cells. Increased levels of SP are found in sarcoid bronchoalveolar lavage fluid. SP acts by binding to the neurokinin-1 receptor and increases secretion of tumor necrosis factor-alpha in many cell types. We sought to determine neurokinin-1 receptor expression in patients with sarcoidosis compared with normal controls. Neurokinin-1 receptor messenger RNA and protein expression were below the limits of detection by reverse transcriptase-polymerase chain reaction and immunohistochemistry in peripheral blood mononuclear cells of healthy volunteers (n = 9) or patients with stage 1 or 2 pulmonary sarcoidosis (n = 10), but were detected in 1\\/9 bronchoalveolar lavage cells of controls compared with 8\\/10 patients with sarcoidosis (p = 0.012) and 2\\/9 biopsies of controls compared with 9\\/10 patients with sarcoidosis (p = 0.013). Immunohistochemistry localized upregulated neurokinin-1 receptor expression to bronchial and alveolar epithelial cells, macrophages, lymphocytes, and sarcoid granulomas. The patient in whom neurokinin-1 receptor was not detected was taking corticosteroids. Incubation of the type II alveolar and bronchial epithelial cell lines A549 and SK-LU 1 with dexamethasone downregulated neurokinin-1 receptor expression. Upregulated neurokinin-1 receptor expression in patients with sarcoidosis may potentiate substance P-induced proinflammatory cytokine production in patients with sarcoidosis.

    Full Text Available We conducted a comparative survey of incidence and prevalence of pulmonary sarcoidosis in Southern (Crimean AR and Northern (Zhytomyr region regions of Ukraine by means of analysis of self-referred cases and cases, revealed at prophylactic radiological examination in 2011. The incidence of sarcoidosis in Crimea was 1.08 per 100 000 adult inhabitants; the prevalence was 4,59 per 100 000. In Zhytomyr region the incidence value (2,62 per 100 000 exceeded an equivalent value in Crimea by 2,4 times. The prevalence (7,86 per 100 000 was also higher than in Crimea by 1,7 times. Taking into account a significant impact of climate factor on sarcoidosis epidemiology, the incidence and prevalence of disease in Northern and Southern regions should be considered polar as for the regions of Ukraine. This makes it possoble to conclude that mean incidence of sarcoidosis in Ukraine ranges from 1,1 to 2,6 per 100 000 adult population, whereas the prevalence – from 4,6 to 7,9 per 100 000, which is equivalent to the level of Southern European countries.

    One hundred and sixty-four patients with pulmonary fibrosis were examined by CT and by conventional radiological methods. Sixty patients had asbestosis, thirty-nine silicosis, forty sarcoidosis and twenty-five had idiopathic pulmonary fibrosis. CT is superior to conventional radiography in evaluating interstitial pulmonary changes, particularly of the pleura and the lung parenchyma. In sixty-nine patients there were some findings which could only be demonstrated by CT. In asbestosis, silicosis and sarcoidosis the CT classification of the lung parenchyma which we have suggested produces significantly better correlation with vital capacity than can be achieved from conventional chest films, according to the guidelines of the I.L.O.

    Regional pulmonary glucose metabolism (MR glu ; μmol h -1 g -1 ), extravascular lung density (D EV ; g cm -3 ) and vascular volume (V B ; ml cm -3 ) were measured in a single midthoracic transaxial slice (-2 cm thick) using positron emission tomography (PET) in seven patients with histologically proven sarcoidosis. The measurements were repeated 1-7 months later after steroid therapy (in two cases, no treatment) in order to assess MR glu as an index of inflammation and relate it to routine pulmonary function tests, chest radiography and serum angiotensin converting enzyme (SACE) levels. MR glu was computed from serial lung scans and peripheral venous blood samples for 60 min following an i.v. injection of 18 F-2-fluoro-2-deoxy-D-glucose ( 18 FDG). Both MR glu (which was increased in six of seven patients) and elevated SACE levels returned to normal in those patients treated with high-dose steroids. Regional vascular volume was normal in six of seven cases and did not change significantly with therapy. The high tissue density measured in all patients decreased significantly in two of three patients treated with 40 mg prednisolone daily. The abnormal MR glu observed in active sarcoidosis becomes normal pari passu with SACE levels during high-dose steroid therapy. We conclude that MR glu measured with 18 FDG and PET may reflect ''disease activity'' in sarcoidosis in quantitative terms (per gram lung tissue) and in respect of disease distribution. (orig.)

    Sarcoidosis is one of the leading causes of inflammatory eye disease. Ocular sarcoidosis can involve any part of the eye and its adnexal tissues, and may cause uveitis, episcleritis/scleritis, eyelid abnormalities, conjunctival granuloma, optic neuropathy, lacrimal gland enlargement and orbital inflammation. Glaucoma and cataract can be complications from inflammation itself or adverse effects from therapy. Ophthalmic manifestations can be isolated, or associated with other organ involvement. Patients with ocular sarcoidosis can present with a wide range of clinical presentations and severity. Multi-disciplinary approaches are required to achieve the best treatment outcomes for both ocular and systemic manifestations. PMID:26593141

    Standard therapy in chronic hepatitis C virus infection is still a combination of peginterferon alfa2a/2b and ribavirin for 48 weeks. As of side effects, there are organic side effects, such as hematologic disorders, and functional side effects, reflected in the quality of life of hepatitis C patients. Up to 30% of the patients develop specific side effects such as headache, fever, fatigue. Sarcoidosis, known as a granulomatous disease of uncertain cause, is an uncommon finding in this category of patients. This cause-effect relation is accounted for by the convergent action of peginterferon and ribavirin of stimulating type 1 T helper cells and reducing type 2 helper T cells activation. We present the case of male patient known with chronic hepatitis C who developed pulmonary sarcoidosis following antiviral therapy. The first manifestation of the disease was unexplained fever accompanied by pulmonary tract disease. The diagnosis was established by immunophenotyping in bronchial aspirate

  3. Psychological stress in sarcoidosis.

    Wilsher, Margaret L

    2012-09-01

    Sarcoidosis is a chronic illness associated with emotional and physical consequences which impact on quality of life. Although the impact of fatigue is well understood, emotional impacts of sarcoidosis are less commonly recognized and addressed in routine clinical practice. The purpose of this review is to highlight that sarcoidosis can result in considerable psychological distress. Not only is there a high prevalence of depressive symptoms in sarcoidosis, but clinical depressive and anxiety disorders are more common than seen in the general population. Patients with sarcoidosis have perceptions and beliefs about their disease that may impact on their willingness to engage in recommended therapies. They may also exhibit a disordered perception of their disease and a personality profile of neuroticism. Understanding the minimally important clinical difference in the Fatigue Assessment Scale (FAS) and validation of the Sarcoidosis Health Questionnaire (SHQ) across different populations supports the use of these tools in routine clinical practice and clinical trials. Understanding the global impact of sarcoidosis is important for patients and clinicians, and use of validated instruments, such as the SHQ and FAS, allows for more comprehensive assessment of the disease and the impact of any interventions.

    Sarcoidosis is a disease characterized by systemic non-necrotizing granulomas of unknown etiology. Laryngeal sarcoidosis is extremely uncommon, especially among pediatric patients. The clinical presentation and management of this entity in the pediatric population are poorly understood. A comprehensive search in PubMed was conducted to identify all cases in the published literature. We also present a case of isolated pediatric laryngeal sarcoidosis and outline the multidisciplinary approach to evaluation and management. A previously healthy 13-year-old female presented with a five-month history of mild dysphonia, dyspnea on exertion, and diffuse supraglottic edema. Biopsy showed non-necrotizing granulomas. Treatment with methotrexate led to marked improvement. The literature search identified seven previously published cases of pediatric laryngeal sarcoidosis, four in which disease was isolated to the larynx. All patients presented with a symptomatic and diffusely edematous supraglottis. Diagnoses were based on supraglottic biopsies showing non-necrotizing granulomas; all other possible etiopathologies were excluded. Three patients responded to corticosteroid therapy alone, one patient to tumor necrosis factor (TNF) inhibitor and methotrexate, and the remainder to a combination of corticosteroid therapy and surgical debulking. Laryngeal sarcoidosis in the pediatric population is challenging to diagnose and manage. When epithelioid granulomas are encountered histologically, other causes of granulomatous inflammation must be ruled out before a diagnosis of sarcoidosis can be made. Corticosteroid therapy alone may be ineffective. Medical therapy with methotrexate alone or in combination with TNF inhibitors versus surgical debulking alone or as part of multimodality treatment should be considered. A multidisciplinary approach with involvement of an otolaryngologist, pathologist, and rheumatologist is suggested. Copyright © 2015 Elsevier Ireland Ltd. All rights

    Patients with active pulmonary sarcoidosis underwent bronchoalveolar lavage, gallium scan, and serum angiotensin-converting enzyme (ACE) level determination prior to treatment with corticosteroids. Pulmonary function was tested before and after therapy. Increase in vital capacity after treatment ranged from 40 to 1,030 ml; 12 of the 16 patients studied had an increase of more than 200 ml. There was a close correlation between the percentage uptake of gallium scan and the increase of the vital capacity after therapy (r . 0.95, p less than 0.01). There was no relationship between the percentage of lymphocytes obtained on lavage and the changes in vital capacity with therapy (r . 0.05). There was a positive correlation between the changes in vital capacity and the ratio of T4(+):T8(+)lymphocytes (r . 0.62, p less than 0.05) and number of T4 (+) lymphocytes (r . 0.92, p less than 0.01) in the bronchoalveolar fluid. There was a low correlation between the pretreatment ACE level and the change in vital capacity (r . 0.368, p greater than 0.05)

    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.

    Uveitis is a frequent (20-50%) and early feature of sarcoidosis. Typical sarcoid uveitis presents with mutton-fat keratic precipitates, iris nodules, and anterior and posterior synechiae. Posterior involvement includes vitreitis, vasculitis, and choroidal lesions. Cystoid macular edema is the most important and sight-threatening consequence. Histologic proof from a biopsy is the gold standard for the diagnosis of ocular sarcoidosis. An international workshop has recently established diagnostic criteria for sarcoidosis uveitis when biopsy is unavailable or negative: these are based on a combination of ophthalmological findings and laboratory tests. The value of recent techniques, such as PET-scan and endoscopic ultrasound-guided, fine-needle aspiration of intrathoracic nodes needs to be assessed in future studies. Corticosteroids are the mainstay treatment for sarcoidosis. Systemic corticosteroids are indicated when uveitis does not respond to topical corticosteroids or when there is bilateral posterior involvement, especially macular edema and occlusive vasculitis. In up to 15% of cases, additional immunosuppression is used, including methotrexate, azathioprine, and mycophenolate mofetil. Infliximab and adalimumab have been recently proposed for the treatment of refractory or sight-threatening systemic sarcoidosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    The cochleovestibular tract is seldom involved by sarcoidosis (about 50 cases have been described since 1948). As a clinical expression of sarcoidosis, deafness is fluctuant in 50% of all cases, bilateral, and most often associated with facial palsy and uveitis, the vestibular reflexes being reduced. The histological studies demonstrate lesions at all levels from the cochlea to be brain stem, but the main mechanism is an infiltration of the arachnoid vessels. The prognosis of sarcoidosis deafness is usually poor in spite of corticosteroid therapy. This paper is illustrated by 3 cases observed in Avicenne Hospital.

    The differential diagnosis of bilateral parotid gland enlargement in children includes infectious, inflammatory, and neoplastic disorders. We present the case of a 13-year-old male who presented with a 5-week history of bilateral parotid swelling. On exam, both parotid glands were nontender, smooth, and diffusely enlarged. He had slightly elevated inflammatory markers, but other lab results were normal. A neck CT revealed symmetric enlargement of the parotid, submandibular, and sublingual glands. A chest CT revealed scattered peripheral pulmonary nodules and bilateral hilar adenopathy. A parotid gland biopsy showed multiple noncaseating granulomas with multinucleated giant cells surrounded by lymphocytes, consistent with the diagnosis of sarcoidosis. Special stains for acid-fast and fungal organisms were negative. Using this illustrative case, we discuss the differential diagnosis of bilateral salivary gland enlargement in children and review the etiology, diagnosis, clinical manifestations, and treatment of pediatric sarcoidosis.

    Full Text Available Sarcoidosis is a Greek word (Sarco means flesh and Eido means type or like. Cutaneous sarcoidosis occurs in up to one third of patients with systemic sarcoidosis. This disease is characterised by the presence of non – caseating epitheloid cell granulomas in the skin. Cutaneous sarcoidosis presents as a diagnostic challenge to the dermatopathologists due to its varied presentations and almost identical histologic pictures. Hence, exclusion of infectious causes and compatibility with clinical and radiologic picture serve as significant criteria to come up to a diagnosis. Sometimes; skin lesions are the first manifestation of systemic sarcoidosis. This is not a contagious or allergic disease. There is a risk of development of systemic manifestations at a later date; for which a close follow up is a must. We are presenting a case of cutaneous sarcoidosis, which later on progress to sarcoidosis with systemic manifestations.

    Angiotensin-converting enzyme assays and gallium-scan results were obtained from 27 patients with biopsy-proven, clinically active sarcoidosis. Twenty-three of these patients had elevated converting enzyme levels, and 22 had positive gallium-scan results. Three of four patients with normal or borderline-elevated levels of angiotensin-converting enzyme also had positive gallium-scan results. Of 156 nonsarcoid patients (pulmonary and other diseases), 27 were found to have elevated serum converting enzyme levels, and 25 of these had negative gallium-scan results. These results indicate that the combination of an assay of angiotensin-converting enzyme and gallium scan increases diagnostic specificity from 83% to 99% without sacrificing sensitivity. It was concluded that the concurrent use of angiotensin-converting enzyme assay and gallium scan is of value in the diagnosis of sarcoidosis.

    The lesions of sarcoidosis generally show relatively high Ga-67 uptake and the usefulness of scintigraphy using this agent in the evaluation of lesion activity is well known. In this report, we assessed characteristic uptake of Ga-67 in intrathoracic lymph nodes, the shape of which resembled the Greek letter Lambda (Lambda sign) and a symmetrical accumulation in bilateral lacrimal and salivary glands which resembled a Panda face (Panda sign) in patients with sarcoidosis. Our review of Ga-67 scans obtained from 15 patients with sarcoidosis and 1,779 patients with other disorders during the past 3 years revealed that the simultaneous presence of both Lambda and Panda signs was specific to patients with sarcoidosis and was not found in patients with various other disorders, although one of these signs might be observed in patients without sarcoidosis. When Lambda-like sign was observed, chest radiogram or CT was necessary for the differential diagnosis of sarcoidosis. Panda sign was observed frequently among patients who had previously received irradiation of the neck. Our results confirmed that sarcoidosis must be suspected when both Lambda and Panda signs were observed. (author)

The purpose of the present study was to detect possible signs of Rickettsia infection in a Danish population of patients with sarcoidosis. Twenty-six patients with newly diagnosed sarcoidosis were...... interview. Evidence of rickettsial infection was assessed by an immunofluorescence assay testing for antibodies towards Rickettsia as well as specific real-time polymerase chain reaction (PCR) on lung biopsy specimens. We performed fluorescent in situ hybridization (FISH) on the biopsies to detect....... There was no difference in the reported frequency of tick bite between patients and controls. In conclusion, we found no evidence of Rickettsia being involved in the pathogenesis of sarcoidosis in Denmark....

    Localized fibrosis of the lung is usually scar tissue while diffuse pulmonary fibrosis is more often a sign of active disease. Chronic infiltrative lung disease may be classified into four categories: idiopathic pneumonitis, collagen diseases, granulomatosis (sarcoidosis), and caused by known diseases (pneumoconiosis, hypersensitivity pneumonitis, drug-induced lung disease, radiation).

    Full Text Available A sarcoidose é doença granulomatosa multissistêmica que geralmente compromete o trato respiratório e os linfonodos hilares. A pele é comumente afetada, mas raramente o couro cabeludo. Dois casos de sarcoidose com lesões no couro cabeludo são relatados: o primeiro, em paciente negra apresentando áreas de alopecia no couro cabeludo associada a outras lesões cutâneas; e o segundo, em paciente branca, portadora de sarcoidose pulmonar, com alopecia como manifestação cutânea isolada. A sarcoidose de couro cabeludo merece especial atenção, pois nos pacientes com essa forma de lesão cutânea existe alta incidência de acometimento sistêmico.Sarcoidosis is a multi-system granulomatous disease that generally affects the respiratory tract and hilar lymph nodes. The skin is also commonly involved, although cutaneous sarcoidosis on the scalp is rare. Two cases of scalp sarcoidosis are reported: the first presented with patchy alopecia, cutaneous sarcoidosis and also systemic disease in a black patient; the second case is related to an uncommon presentation with alopecia as the single cutaneous manifestation in a Caucasian patient with pulmonary sarcoidosis. Scalp sarcoidosis deserves special attention because there is a high incidence of other systemic lesions with this cutaneous manifestation, thus a careful investigation should be performed in these patients.

    Sarcoidosis is a chronic granulomatous inflammatory disease of unknown etiology with heterogeneous outcomes. This study reviewed the clinical outcome status (COS) and organ involvement of Israeli sarcoidosis patients during a five-year period. Further, we compared our results to the 'World Association of Sarcoidosis and Other Granulomatous Disease' (WASOG) COS and the 'A Case Control Etiologic Study of Sarcoidosis' (ACCESS) instruments in order to evaluate their relevance to the Israeli population. The retrospective study group consisted of 166 sarcoidosis patients for the period of 2010-2015. Data on demographic characteristics, presenting symptoms, co-morbidities, disease duration, lung function tests, treatment program, chest X-ray, and chest high-resolution computed tomography were collected. The median patient age was 62 ± 14, which was significantly higher than the WASOG and ACCESS cohorts (p Israel is a unique and challenging disease with its clinical presentations that differ from previously reported studies.

    Acute vision loss is a devastating problem for patients and a challenging diagnostic dilemma for Emergency Physicians. This chief complaint is one in which we must be adept at quickly evaluating and initiating either care or referral. This case reviews the approach to acute vision loss and shows the importance of expanding the differential in atypical and complex presentations. A 31-year-old, previously healthy, white woman presented to the Emergency Department (ED) with 1 day of painless right eye vision loss. Ocular ultrasound and slit-lamp examination were unremarkable. Fundoscopic examination revealed retinal hemorrhages and papillitis. Her chest X-ray study was significant for bilateral hilar adenopathy, and subsequent lymph node biopsy confirmed the diagnosis of sarcoidosis. Although sarcoidosis is more common in African Americans, it must be considered in all patients in the appropriate clinical context. Sarcoidosis is an important diagnosis to include on the differential of many chief complaints that present to the ED, including acute vision loss and dyspnea. Published by Elsevier Inc.

    Full Text Available Tuberculosis (TB is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB. Latent TB is a state in which M. tuberculosis survives in the body without causing overt signs and symptoms. People with latent TB are noncontagious. However, M. tuberculosis can become active in the body, multiply, and cause overt TB. Sarcoidosis, on the other hand, is an autoimmune disease of unknown etiology which can affect multiple systems of the body. Nonspecific constitutional symptoms, such as fever, fatigue, malaise, and weight loss, are present in approximately one-third of patients. Chest X-ray usually shows hilar and mediastinal lymphadenopathy. Although the lungs are the most common sites of inflammation, sarcoidosis can also involve other organs, such as the eyes (intraocular and adnexal, skin, lymph nodes, salivary glands, heart, spleen, liver, and the nervous system. Recent investigations have provided further insights into the genetic basis of sarcoidosis and the way genotype determines the clinical presentation and phenotype of patients. Histopathologic features are usually insufficient for diagnosis of sarcoidosis. Diagnosis of sarcoidosis in endemic areas for TB can become a great challenge. Both TB and sarcoidosis are granulomatous diseases; TB is characterized by caseating granulomas, whereas sarcoidosis is characterized by noncaseating granulomas. New cases of sarcoidosis are increasingly being diagnosed in areas endemic for TB due to increased orientation of physicians and availability of diagnostic modalities

    Pulmonary hypertension commonly complicates chronic obstructive pulmonary disease and interstitial lung disease. The association of chronic lung disease and pulmonary hypertension portends a worse prognosis. The pathophysiology of pulmonary hypertension differs in the presence or absence of lung disease. We describe the physiological determinants of the normal pulmonary circulation to better understand the pathophysiological factors implicated in chronic parenchymal lung disease-associated pulmonary hypertension. This review will focus on the pathophysiology of 3 forms of chronic lung disease-associated pulmonary hypertension: idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease, and sarcoidosis.

    Sarcoidosis is a poorly understood chronic inflammatory condition. Infiltration of affected organs by lymphocytes is characteristic of sarcoidosis, however previous reports suggest that circulating lymphocyte counts are low in some patients with the disease. The goal of this study was to evaluate lymphocyte subsets in peripheral blood in a cohort of sarcoidosis patients to determine the prevalence, severity, and clinical features associated with lymphopenia in major lymphocyte subsets. Lymphocyte subsets in 28 sarcoid patients were analyzed using flow cytometry to determine the percentage of CD4, CD8, and CD19 positive cells. Greater than 50% of patients had abnormally low CD4, CD8, or CD19 counts (p<4x10(-10)). Lymphopenia was profound in some cases, and five of the patients had absolute CD4 counts below 200. CD4, CD8, and CD19 lymphocyte subset counts were significantly correlated (Spearman's rho 0.57, p = 0.0017), and 10 patients had low counts in all three subsets. Patients with severe organ system involvement including neurologic, cardiac, ocular, and advanced pulmonary disease had lower lymphocyte subset counts as a group than those patients with less severe manifestations (CD4 p = 0.0043, CD8 p = 0.026, CD19 p = 0.033). No significant relationships were observed between various medical therapies and lymphocyte counts, and lymphopenia was present in patients who were not receiving any medical therapy. Significant lymphopenia involving CD4, CD8, and CD19 positive cells was common in sarcoidosis patients and correlated with disease severity. Our findings suggest that lymphopenia relates more to disease pathology than medical treatment.

    Full Text Available Sarcoidosis is not an uncommon disease. Unfortunately, the awareness amongst clinicians is lacking and due to overwhelming prevalence of tuberculosis, a disease with many similar features, the diagnosis is missed and often delayed. The gold standard investigation finding in the diagnosis of sarcoidosis is the presence of noncaseating tuberculoid granuloma, also known as sarcoid or sarcoid-like granuloma. Some classical chest X-ray findings, clinico-radiological dissociation. Suggestive organ lesions, negative Mantoux test (MT, development of MT site granuloma, hypercalcemia, hypercalciuria and raised serum angiotensin converting enzyme (SACE value and negative tests for tuberculosis are usually hekpful in the diagnosis of sarcoidosis.

    A case of isolated sarcoidosis of the thyroid gland, associated with hyperthyroidism, is reported in a 28-year-old male patient whose thyroid was removed for hyperthyroid multinodular goitre. Histology revealed a regressive adenoma and sarcoidosis in non-adenomatous thyroid residue. Further diagnosis, therapeutic management and a 3-year follow-up did not disclose any specific changes or involvement of other tissues. Isolated thyroidal sarcoidosis with hyperthyroid alterations are extremely rare and mostly chance findings; simultaneous occurrence of thyroid sarcoidosis and hyperthyroidism may be a symptom of gland infiltration for which an adequate explanation is still lacking.

    Malakoplakia is an acquired granulomatous disorder first described by Michaelis and Gutmann in 1902. The pathogenesis of malakoplakia is hardly known, but it thought to be secondary to an acquired bactericidal defect in macrophages occurring mostly in immunosuppressed patients. 63-year-old female patient had been treated with methylprednisolone for ten years, because of pulmonary sarcoidosis. For six month, recurrent abdominal abscess and vesico-cutaneous fistula developed. Histological examination proved malakoplakia, and Escherichia coli was detected in the abscess cavity. Hematoxyline eosin staining, periodic acid-Schiff, Berlin-blue and Kossa reactions were performed. Microscopically malakoplakia consists of mainly macrophages, known as von Hansemann cells with scattered targetoid intracytoplasmic inclusions known as Michaelis-Gutmann bodies. In our presented case, after urological-surgical intervention and antibiotic therapy, the patient became free from complaints and symptoms. Malakoplakia has been described in numerous anatomic locations, mainly in the urogenital tract. Malakoplakia may be complicated with fistulas in different locations: vesico-coccygeal, rectoprostatic, anorectal fistulas have been were reported in the literature, while 6 cases of malakoplakia with Boeck's sarcoidosis are published. In the presented case sarcoidosis and the 10-year immunosuppressive treatment with methylprednisolone might have been in the background of abdominal wall malakoplakia, complicated by vesico-cutaneous fistula. The patient was successfully treated with surgery and the followed antibiotic therapy.

    Full Text Available Sarcoidosis is a systemic, multi-organ disease of unknown etiology characteristically defined by the development of non-caseating granulomas. The development of sarcoidosis has been associated with a number of environmental and microbacterial factors coupled with genetic susceptibility. Depending on the type, location and distribution of disease, sarcoidosis can cause functional impairment, symptomatic distress, scarring and disfigurement. The advent of lasers as precise, minimally destructive surgical tools has allowed for their development as promising alternatives that minimize the morbidity associated with current therapies.In this paper, we reviewed the role of laser therapy in the treatment of cutaneous sarcoidosis. A comprehensive search of the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literatures investigating the role of laser therapy in the treatment of cutaneous sarcoidosis. In our opinion, laser therapy, particularly PDL, appears to be an effective, safe and generally well-tolerated modality for the treatment of cutaneous sarcoidosis and should be considered in patients with localized cutaneous disease that is refractory to conventional treatments. Less is known about the efficacy and tolerability of ablative laser therapy for the treatment of cutaneous sarcoidosis, though the limited data appears promising as well. With that said, however, the data is limited and warrants a need for additional larger, randomized controlled studies to further investigate the utility and efficacy of laser therapy in the treatment of cutaneous sarcoidosis.

  18. Development of sarcoidosis 6-month post discontinuation of etanercept: coincidence or real association?

    2011-08-01

    There have been numerous reports of granulomatous diseases developing in patients receiving anti-tumour necrosis factor (TNF) therapy. Herein, we report a patient who developed sarcoidosis 6 months after discontinuation of etanercept. To date, all reported cases have occurred in patients undergoing ongoing treatment with TNF blockers with resolution on its discontinuation. A 47-year-old man was diagnosed with seropositive rheumatoid arthritis (RA) in 2003. He was initially treated with methotrexate and corticosteroids. In 2005, adalimumab was added due to ongoing disease activity. However, he had persistent low-grade synovitis of bilateral wrist joints and remained oral glucocorticoids dependent. In October 2008, adalimumab was switched to etanercept with marginal benefit; however, etanercept was continued until March 2009. Rituximab was discontinued due to an immediate allergic reaction. In September 2009, he developed bilateral ankle synovitis with erythema nodosum. Further investigations (chest X-ray and CT scan of thorax) revealed new development of bilateral hilar lymphadenopathy and interstitial nodular changes typical of sarcoidosis. His baseline therapy of methotrexate was continued. His recent repeat chest X-ray and CT scan of thorax (March 2010) has shown significant spontaneous resolution of his mediastinal lymphadenopathy and pulmonary nodules. Apart from the initial brief course of NSAIDs, his sarcoidosis resolved spontaneously without requiring any further therapy. For his rheumatoid arthritis, he has been recently commenced on abatacept and his baseline therapy of methotrexate has been continued. It remains speculative as to whether the concurrence of RA and sarcoidosis is purely serendipitous, or is related to an immunodysregulatory state attributable to TNF blockade.

    Gingivitis due to sarcoidosis is a relatively rare condition. Gingivitis or isolated gingival involvement may be the first sign of systemic sarcoidosis. We report the case of a 37 year-old woman with isolated gingivitis due to sarcoidosis confirmed by biopsy. Following treatment with a systemic corticosteroid (prednisolone 40 mg/day), all clinical and radiologic findings were completely improved. In cases of chronic and intractable gingivitis, systemic sarcoidosis should be suspected. It should be confirmed with a biopsy, and the patient should be referred to a chest disease clinic to exclude other organ involvement. Copyright © 2013 Elsevier Inc. All rights reserved.

  20. How are cancer and connective tissue diseases related to sarcoidosis?

    Chopra, Amit; Judson, Marc A

    2015-09-01

    Several studies have suggested an association between sarcoidosis and cancer, and between sarcoidosis and connective tissue diseases (CTDs). In this review, we discuss the evidence supporting and refuting these associations. In terms of a cancer risk in sarcoidosis patients, the data are somewhat conflicting but generally show a very small increased risk. The data supporting an association between sarcoidosis and CTD are not as robust as for cancer. However, it appears that scleroderma is the CTD most strongly associated with sarcoidosis. There are several important clinical and research-related implications of the association of sarcoidosis and CTDs. First, rigorous efforts should be made to exclude alternative causes for granulomatous inflammation before establishing a diagnosis of sarcoidosis. Second, the association between sarcoidosis and both cancer and CTDs may yield important insights into the immunopathogenesis of all three diseases. Finally, these data provide insight in answering a common question asked by sarcoidosis patients, 'Am I at an increased risk of developing cancer?' We believe that although there is an increased (relative) risk of cancer in sarcoidosis patients compared with the general population, that increased risk is quite small (low absolute risk).

    Presentation of the etiology, pathology, clinical course, radiology and differential diagnostics of skeletal sarcoidosis. Noncaseating epithelioid cell granulomas can trigger solitary, multiple or disseminated osteolysis, reactive osteosclerosis and/or granulomatous synovitis. The incidence of sarcoidosis is 10-12 per 100,000 inhabitants per year. Skeletal involvement is approximately 14 %. Skeletal involvement occurs almost exclusively in the stage of lymph node and pulmonary manifestation. Most cases of skeletal involvement are clinically asymptomatic. In the case of synovial involvement, unspecific joint complaints (arthralgia) or less commonly arthritis can occur. Typical skin alterations can be diagnostically significant. Punch out lesions osteolysis, coarse destruction and osteosclerosis can occur, which are best visualized with projection radiography and/or computed tomography. Pure bone marrow foci without interaction with the bone can only be detected with magnetic resonance imaging (MRI) and more recently with positron emission tomography (PET), mostly as incidental findings. There is a predeliction for the hand and trunk skeleton. Skeletal tuberculosis, metastases, multiple myeloma, Langerhans cell histiocytosis and sarcoid-like reactions in solid tumors must be differentiated. The key factors for correct diagnosis are thorax radiography, thorax CT and dermatological manifestations. (orig.)

    Full Text Available Sarcoidosis is classified as an acquired systemic granulomatous disease. Because of the fact that sarcoidosis affects multiple tissues and organs, it is characterized by many potential signs and symptoms, as well as by the presence of non-caseating granulomas in the organs involved. Although oral sarcoidosis is relatively rare, it may however, present in the oral cavity. This report presents a rare case of sarcoidosis with the initial presenting symptom as severe generalized gingival enlargement. The gingival enlargement was treated by gingivectomy. After histopathological examination of gingival biopsy and certain special investigations, a diagnosis of sarcoidosis was made.

    In light of the marked global health impact of tuberculosis (TB), strong focus has been on identifying biosignatures. Gene expression profiles in blood cells identified so far are indicative of a persistent activation of the immune system and chronic inflammatory pathology in active TB. Definition of a biosignature with unique specificity for TB demands that identified profiles can differentiate diseases with similar pathology, like sarcoidosis (SARC). Here, we present a detailed comparison between pulmonary TB and SARC, including whole-blood gene expression profiling, microRNA expression, and multiplex serum analytes. Our analysis reveals that previously disclosed gene expression signatures in TB show highly similar patterns in SARC, with a common up-regulation of proinflammatory pathways and IFN signaling and close similarity to TB-related signatures. microRNA expression also presented a highly similar pattern in both diseases, whereas cytokines in the serum of TB patients revealed a slightly elevated proinflammatory pattern compared with SARC and controls. Our results indicate several differences in expression between the two diseases, with increased metabolic activity and significantly higher antimicrobial defense responses in TB. However, matrix metallopeptidase 14 was identified as the most distinctive marker of SARC. Described communalities as well as unique signatures in blood profiles of two distinct inflammatory pulmonary diseases not only have considerable implications for the design of TB biosignatures and future diagnosis, but they also provide insights into biological processes underlying chronic inflammatory disease entities of different etiology.

    Localized fibrosis of the lung is usually scar tissue while diffuse pulmonary fibrosis is more often a sign of active disease. Chronic infiltrative lung disease may be classified into four categories: idiopathic pneumonitis, collagen diseases, granulomatosis (sarcoidosis), and caused by known diseases (pneumoconiosis, hypersensitivity pneumonitis, drug-induced lung disease, radiation).

    BACKGROUND: Sarcoidosis is a multiorgan, granulomatous, inflammatory disease with unknown aetiology. Familial clustering of cases and ethnic variation in the epidemiology suggests a genetic influence on the disease susceptibility. AIM: This paper reports twin concordance and heritability estimates...... of sarcoidosis in order to assess the overall contribution of genetic factors to the disease susceptibility. METHODS: Monozygotic and dizygotic twins enrolled in either the Danish or the Finnish population-based, national Twin Cohorts (61,662 pairs in total) were linked to diagnostic information on sarcoidosis.......012. Compared to the general population we found an 80-fold increased risk of developing sarcoidosis in co-twins of affected monozygotic brothers or sisters. The increased risk in dizygotic twins was on the other hand only 7-fold. Aetiological model fitting gave a heritability of sarcoidosis of 0.66 (95% CI 0...

    Poor sleep is common among patients with medical disorders. Sleep disturbances can be a cause of fatigue and poor quality of life for patients suffering from sarcoidosis. Studies on subjective sleep quality or prevalence of insomnia have not been reported so far. The aim of this study was to investigate the subjectively reported sleep quality and its relation to psychological and physical factors in sarcoidosis patients. 1197 patients from Germany diagnosed with sarcoidosis were examined using the Pittsburgh Sleep Quality Index (PSQI), the Medical Research Council (MRC) dyspnea scale, the Hospital Anxiety and Depression Scale (HADS) and the Multidimensional Fatigue Inventory (MFI). 802 patients (67%) had PSQI global scores >5, indicating subjectively poor quality of sleep. The mean PSQI score was 7.79 ± 4.00. Women reported a significantly inferior individual quality of sleep than men. The subjective quality of sleep was lowered significantly with increasing dyspnea for men and women. 294 patients (25%) had PSQI global scores >10 usually found in patients with clinically relevant insomnia. In this group 86% had high values for fatigue, 69% for anxiety, and 59% for depression. The prevalence of known sleep apnea was 8.7% and 15.7% for restless legs. Poor subjective sleep quality in sarcoidosis patients is about twice as common as in the general population and is associated with fatigue, anxiety, depression and dyspnea. Questions about sleep complaints should therefore be included in the management of sarcoidosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    Sarcoidosis is a multi-system granulomatous disease of unknown etiology. The skin is involved in 25% of cases. Studies on cutaneous sarcoidosis from our region are lacking. This study was conducted to describe clinical and histopathologic findings in all patients diagnosed with cutaneous sarcoidosis at the American University of Beirut Medical Center between 1992 and 2010 and to compare findings with those published in the literature. Clinical charts of patients with cutaneous sarcoidosis were retrospectively reviewed. Extracutaneous lesions were classified by organ involvement. Treatment was documented. Pathology specimens were reviewed. Cutaneous sarcoidosis was diagnosed in 76 Lebanese patients, 79% of whom were women. Mean age at diagnosis was 48 years. A total of 29% of patients had systemic disease that was commonly associated with lupus pernio lesions and subcutaneous sarcoidosis. The most common cutaneous lesions were sarcoidal plaques. The histopathologic features in our series did not differ from those described in the literature, except for the documented presence of a grenz zone. Interestingly, 23% of biopsy specimens contained perineural granulomas, raising the possibility of tuberculoid or borderline tuberculoid leprosy. Foreign bodies were detected in 10% of cases (all had systemic involvement), supporting the opinion that sarcoidosis and granulomatous foreign body reaction are not mutually exclusive. The clinical and histopathologic features of cutaneous sarcoidosis patients in the present series are generally comparable with those published in the literature, with minor differences. Clinically, the most commonly seen lesion was plaque. Microscopically, cutaneous sarcoidosis may exhibit a grenz zone and may show perineural inflammation and foreign bodies. © 2014 The International Society of Dermatology.

    We herein describe a second Japanese case of sarcoidosis presenting Addison's disease. A 52-year-old man was diagnosed with sarcoidosis based on clinical and laboratory findings, including bilateral hilar lymphadenopathy and elevated levels of serum angiotensin-converting enzyme and lysozyme, as well as the presence of noncaseating epithelioid granulomas. The patient also exhibited general fatigue, pigmentation, weight loss, hypotension and hyponatremia, suggestive of chronic adrenocortical insufficiency. An endocrine examination confirmed primary adrenocortical insufficiency. This case suggests the direct involvement of sarcoid granuloma in the adrenal glands.

A biopsia cirúrgica revelou a presença de granulomas nao necrotizantes com células gigantes multinucleadas, compatível com sarcoidose. Apesar de se tratar de uma sarcoidose pulmonar estádio III, a doente apresentava -se assintomática, o estudo funcional ventilatorio era normal e não havia sinais de envolvimento extratoracico, pelo que foi decidido não iniciar tratamento. Houve remissão espontânea das lesões, comprovada em tomografia computorizada de alta resolução após um ano.The clinical presentation of sarcoidosis is diverse and in over 90% of patients there is pulmonary involvement. The most common features of the radiographic findings at the time of diagnosis are bilateral hilar lymphadenopathy and pulmonary infiltration. The authors report the case of a young female patient who presented with multiple bilateral nodular shadows on chest radiograph. Surgical biopsy revealed non-necrotizing granulomas with occasional multinucleated giant cells compatible with sarcoidosis. Al-though this was a case of stage III pulmonary disease, the patient was asymptomatic, lung function tests were normal and there were no signs of extrathoracic involvement. Spontaneous remission occurred without treatment as shown on high resolution CT scan follow-up, one year later.

    The current study aimed to investigate incidence, prevalence and regional distribution of sarcoidosis in Switzerland with respect to environmental exposures. All sarcoidosis patients hospitalised between 2002 and 2005 were identified from the Swiss hospital statistics from the Swiss Federal Office for Statistics (Neuchâtel, Switzerland). Regional exposure characteristics included the regional distribution of different industrial sectors, agriculture and air quality. Co-inertia analysis, as well as a generalised linear model, was applied. The prevalence of "ever-in-life" diagnosed sarcoidosis, currently active sarcoidosis and sarcoidosis requiring hospitalisation was 121 (95% CI 93-149), 44 (95% CI 34-54) and 16 (95% CI 10-22) per 100,000 inhabitants, respectively. The mean annual incidence of sarcoidosis was 7 (95% CI 5-11) per 100,000 inhabitants. The regional workforce in the metal industry, water supply, air transport factories and the area of potato production, artificial meadows (grassland) and bread grains were positively associated with the frequency of sarcoidosis. The prevalence of sarcoidosis was higher than assumed based on former international estimates. Higher frequency was found in regions with metal industry and intense agriculture, especially production of potatoes, bread grains and artificial meadows.

    Exogenous (cosmetic) ochronosis is caused by the long term use of skin-lightening creams containing hydroquinone. Three cases of systemic sarcoidosis with cutaneous sarcoidal granulomas, which developed on ochronotic skin were last described by Jacyk in 1995. Dogliotti and Leibowitz previously reported cases of granulomatous ochronosis with sarcoid-like histological changes but with no associated systemic sarcoidosis. We report two additional cases of cutaneous sarcoidal granulomas, which developed on a background of cosmetic ochronosis in patients recently diagnosed with systemic sarcoidosis.

    Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18 FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

    Full Text Available Sarcoidosis, a systemic granulomatous syndrome invariably affecting the lung, typically spontaneously remits but in ~20% of cases progresses with severe lung dysfunction or cardiac and neurologic involvement (complicated sarcoidosis. Unfortunately, current biomarkers fail to distinguish patients with remitting (uncomplicated sarcoidosis from other fibrotic lung disorders, and fail to identify individuals at risk for complicated sarcoidosis. We utilized genome-wide peripheral blood gene expression analysis to identify a 20-gene sarcoidosis biomarker signature distinguishing sarcoidosis (n = 39 from healthy controls (n = 35, 86% classification accuracy and which served as a molecular signature for complicated sarcoidosis (n = 17. As aberrancies in T cell receptor (TCR signaling, JAK-STAT (JS signaling, and cytokine-cytokine receptor (CCR signaling are implicated in sarcoidosis pathogenesis, a 31-gene signature comprised of T cell signaling pathway genes associated with sarcoidosis (TCR/JS/CCR was compared to the unbiased 20-gene biomarker signature but proved inferior in prediction accuracy in distinguishing complicated from uncomplicated sarcoidosis. Additional validation strategies included significant association of single nucleotide polymorphisms (SNPs in signature genes with sarcoidosis susceptibility and severity (unbiased signature genes - CX3CR1, FKBP1A, NOG, RBM12B, SENS3, TSHZ2; T cell/JAK-STAT pathway genes such as AKT3, CBLB, DLG1, IFNG, IL2RA, IL7R, ITK, JUN, MALT1, NFATC2, PLCG1, SPRED1. In summary, this validated peripheral blood molecular gene signature appears to be a valuable biomarker in identifying cases with sarcoidoisis and predicting risk for complicated sarcoidosis.

    Stage I: Hilar Adenopathy With normal lung function observe, as it often resolves. With reduced lung function observe for 6-12 months. Treat if there is progression or persistence. With erythema nodosum use mild anti-inflammatory agents such as salicylates or like drugs. Stage II: Adenopathy + Pulmonar Infiltrates With normal or slightly reduced lung function observe; treat if it worsens. Treat if there is no remission in 6-12 months. With reduced lung function treat, possibly for many years or a lifetime. Stage III: Pulmonary Infiltrates +/- Fibrosis Without Adenopathy There is reduced lung function. Treat, demonstrate improvement, follow patients with serial measurements of vital capacity at least. Other Indications for Treatment Other indications for treatment include myocardial sarcoidosis, cerebral sarcoidosis (although the outcome is less certain), serious hepatic or renal sarcoidosis, hypercalcemia, persistent systemic symptoms, or other serious organ or functional impairment. Assess each patient individually and completely. Use good clinical judgement. It is clear that treatment that is too little or too late is of little benefit. Even the statistical results form a perfectly controlled study cannot provide absolute direction for the individual patient. As clinicians we are frequently called upon to apply considered judgements without hard data to predict the outcome. We also maintain the flexibility to change our therapeutic programs when circumstances change, either in the patient or in our knowledge. We can be grateful we have a treatment as good as corticosteroids and must try to exercise our best judgement as to when it should be instituted.

    The relationship between the level of serum angiotensin converting enzyme (SACE) and the total body granuloma load in patients with sarcoidosis was studied in two groups using SACE levels and total body gallium67 scans. The study group consisted of 22 patients with SACE levels greater than or equal to 100 U/ml (EH-SACE group) and the control group consisted of 24 patients consecutively diagnosed to have sarcoidosis in a one year period with SACE level of less than 80 U/ml. The average number of organs involved in the EH-SACE group was 3.9 +/- 1 compared to 2.3 +/- 1 in the control group (p less than 0.0001). The incidence of extra pulmonary organ involvement in the EH-SACE group was 2.2 +/- 1 organs compared to 1.0 + 0.8 in the control group (p less than 0.0002). The SACE level was correlated with the number of organs involved for all patients with sarcoidosis (r = .55; p less than .0001). Following corticosteroid therapy for 39 +/- 41 weeks the SACE dropped to 64 +/- 45 units in the EH-SACE group. But it took only 13 +/- 10 weeks to normalize the SACE level to 27 +/- 9 units in the control group. The EH-SACE group patients were followed for 114 +/- 64 weeks and 73% of them still have active sarcoidosis requiring repeated cycles of corticosteroid therapy, while after 42 +/- 23 weeks of follow up only 10% of patients from the control group were still on therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

    Sarcoidosis is the disease in which increased levels of serum Angiotensin-converting enzyme (sACE) are most often detected. It has recently been shown that the deletion (D) or the insertion (I) of a 250bp-DNA fragment in the ACE gene accounts for three main ACE genotypes (i.e., II, ID, and DD) and for 47% of total phenotypic variance in sACE level. The aim of our work was to investigate whether or not patients with sarcoidosis have an increased incidence of those ACE genotypes coding for highest sACE levels and to investigate whether or not sACE level in sarcoidosis is related to ACE genotypes. We studied 61 unrelated patients with sarcoidosis (test group) and 80 unrelated healthy control subjects (control group). The ACE I and D alleles were detected with polymerase chain reaction on genomic DNA. In the control group we found an ACE genotype distribution that agreed with the Hardy-Weinberg proportion. The ACE genotype distribution was not significantly different in the test group. There was no correlation between ACE genotype and roentgenologic stage of sarcoidosis. Plotting the sACE level in the control group against ACE genotype, we found a trend of increasing mean sACE value according to the order II sACE values plotted against roentgenologic stage, according to the order Stage I sACE values in sarcoidosis according to both ACE genotype and roentgenologic stage would suggest that both mechanisms play a role in determining sACE level.

    2016-01-01

    Full Text Available Introduction. Sarcoidosis is a rare multisystemic granulomatous inflammatory disease of unknown etiology affecting the respiratory system, skin, and eyes. Sarcoidosis outside the lacrimal gland is rare. The case study concerns a patient with a final diagnosis of orbital sarcoidosis. Case Report. A 37-year-old male patient went to the ophthalmic emergency room complaining of pain in the left eye, diplopia, and decreased visual acuity. An external eye examination showed hard and cold edema of the lower eyelid, ocular motility with limitation of adduction, and discreet ipsilateral proptosis. Magnetic resonance of the orbit showed left eye proptosis and thickening and increase of soft tissues associated with heterogeneous impregnation of contrast in the infralateral region of the left eyelid. A biopsy of the lesion showed a chronic inflammatory process, with numerous compact nonnecrotizing granulomas surrounded by lamellar hyaline collagen, providing histological confirmation of sarcoidosis. Discussion. A biopsy of the orbital tumor is essential for the diagnosis of sarcoidosis, in addition to the search for systemic findings such as hilar adenopathy or parenchymal lung disease found in 90% of patients.

    1990-01-01

    Assessment of gallium-67 ( 67 Ga) uptake in the salivary and lacrimal glands and intrathoracic lymph nodes was made in 605 consecutive patients including 65 with sarcoidosis. A distinctive intrathoracic lymph node 67 Ga uptake pattern, resembling the Greek letter lambda, was observed only in sarcoidosis (72%). Symmetrical lacrimal gland and parotid gland 67 Ga uptake (panda appearance) was noted in 79% of sarcoidosis patients. A simultaneous lambda and panda pattern (62%) or a panda appearance with radiographic bilateral, symmetrical, hilar lymphadenopathy (6%) was present only in sarcoidosis patients. The presence of either of these patterns was particularly prevalent in roentgen Stages I (80%) or II (74%). We conclude that simultaneous (a) lambda and panda images, or (b) a panda image with bilateral symmetrical hilar lymphadenopathy on chest X-ray represent distinctive patterns which are highly specific for sarcoidosis, and may obviate the need for invasive diagnostic procedures

    Disorders of calcium metabolism, especially hypercalcemia and hypercalceuria, are common in sarcoidosis. They are caused by extra renal unsuppressed production of 1,25 dihydroxy vitamin D at the level of the sarcoid granuloma. Hormonal changes during pregnancy have a physiological synergistic effect on this mechanism, which is primarily parathyroid hormone (PTH) dependant. However, the combination of primary hypoparathyroidism with hypocalcemia and sarcoidosis is rare.

    Sarcoidosis is an idiopathic multisystem granulomatous disease that commonly involves the skin in 25% of affected patients. Because lesions assume a vast array of morphologies, a classification dividing them into specific (with presence of typical granulomas in the biopsy) or nonspecific (not containing granulomas) has been proposed. In the first group the variant morpheaform is considered exceptional. We review the cases reported in the literature and describe the possible differential diagnosis. We highlight the importance of recognizing the very atypical presentation of sarcoidosis and its ability to mimic morpheaform or sclerosis diseases in our patients.

    Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis. To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US. Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 ("index date") were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date ("outcome period"). A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p economic burden to payers in the first year following diagnosis.

    2014-07-01

    Full Text Available A 60 year old male with a medical history of pulmonary sarcoidosis and chronic low testosterone presented to his allergist for excessive lacrimation. Computed tomography (CT scan of sinuses ordered for possible blocked nasolacrimal duct revealed an abnormal expansion of the sella turcica. Magnetic resonance imaging suggested a homogeneously enhancing 4 cm soft tissue mass enveloping the internal carotid and abutting the optic nerves. Since the patient indicated no symptoms, it was felt to be consistent with a pituitary incidentaloma. Laboratory investigation showed only minimally elevated prolactin. Visual field testing at the office was normal but computed campimetry was suggestive of few minimally depressed points in the supra-temporal quadrant on the right. Even with high suspicion of neurosarcoidosis, the patient had a surgical indication so he underwent transsphenoidal excision of the mass with no complications. Pathology was consistent with a null-cell pituitary adenoma.

    Isolated laryngeal sarcoidosis is a very rare disease. In most cases, it will present as a supraglottic pale edematous swelling. In our case, the patient presented with hoarseness and dyspnea during exertion. Laryngeal examination did show not only supraglottic edema but also prominent subglottic swelling and edematous true vocal folds. Histology showed noncaseating granulomas. After excluding other causes and localizations, the patient was diagnosed with laryngeal sarcoidosis and treated with systemic corticosteroid with good result. We describe our case of isolated transglottic sarcoidosis and discuss the disease, its presentation, diagnosis, and therapeutic options. Copyright © 2013 The Voice Foundation.

    Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis. We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement. All patients have biopsy-positive sarcoidosis of the lungs and/or mediastinal lymph nodes. Blood samples for ACE serum levels were obtained from all patients. Aqueous humor samples were taken by paracentesis with a 25-gauge needle in local anesthesia. With appropriate statistical tests, we compared ACE activity in serum and aqueous humor in patients with and without ocular sarcoidosis. The majority of our patients with ocular sarcoidosis were female (12/20), also in the group with systemic sarcoidosis and without ocular involvement (12/6). Mean age of the whole analyzed group of sarcoidosis patients was 45 ± 6 years. There is no statistically significant difference in ACE activity in serum between two groups of patients (with and without ocular sarcoidosis). There is statistically significant difference in ACE activity in aqueous humor among patients with ocular and nonocular sarcoidosis. ACE activity in aqueous humor is significantly higher in patients with ocular sarcoidosis. Increased ACE activity in aqueous humor can point to a diagnosis of ocular sarcoidosis, without the need for ocular biopsy.

    2015-03-01

    Because of the rarity of neuro-ophthalmic sarcoidosis, there are no therapeutic guidelines based on evidence-based medicine for this disorder. Review of literature combined with personal experience. Corticosteroids are the preferred initial therapy for neuro-ophthalmic sarcoidosis. If patients cannot tolerate the requisite dose of corticosteroid needed to control their disease, or if corticosteroids fail to adequately control the disease process, the choices of a second agent are based on the consideration of rapidity of clinical response and the safety profile. Although methotrexate and mycophenolate mofetil are the medications that are often selected after corticosteroid failure, more rapidly acting agents that have been used are infliximab and intravenous cyclophosphamide.

    Full Text Available Autoimmune endocrinopathies and, less commonly, thyroid autoimmune disease have been reported in patients with sarcoidosis. Similarities exist in the pathogenesis of these two conditions. Concomitant sarcoidosis in the thyroid gland in patients with Graves′ disease may contribute to the resistance to antithyroid drugs and radioiodine therapy. We present the clinical, laboratory, imaging, and pathologic findings of a patient with Graves′ disease who was unresponsive to medical management. This 37-year-old man presented with thyrotoxicosis. Thyroid hormone assays and 99m Technitium findings were consistent with Graves′ disease. He was also found to have hilar lymphadenopathy. Patient failed to achieve remission with high doses of antithyroid drugs and 2 sessions of radioiodine ablative therapy.Histopathology of lymph nodesdisclosed noncaseating granulomas, consistent with sarcoidosis. Patient′s thyrotoxicosis subsided only following steroid administration. The histopathology of the thyroid gland on aspiration and the subsidence of symptoms with steroids reiterate the possibility of thyroid sarcoidosis. This diagnosis needs biopsy for confirmation, which our patient didn′t consent for.

    2017-07-01

    Conclusion: Co-existence of sarcoidosis, CD and APS is extremely rare. APS should be recognized as an accompanying disorder of sarcoidosis and antiphospholipids measured especially when there is a history of thrombosis or miscarriages. CD should not be overlooked in association to sarcoidosis, given the shared immunological and genetic background, even in the absence of a typical presentation of the disease.

    Full Text Available Sarcoidosis is an enigmatic, multisystem granulomatous disease of unknown etiology and wide range of clinical presentations. Case report: A 54-year-old female presented with facial rash: polymorphic, round, infiltrated erythematous plaques, 1 - 3 cm in size, disseminated on several areas of the face. The medical history was consistent with dermatitis herpetiformis and persistent intrahepatic cholestasis. The laboratory test results suggested celiac disease (strong positivity of IgA anti-tissue transglutaminase antibodies but upper endoscopy was not performed to confirm it. The skin biopsy revealed noncaseating epithelioid-cell granulomas, and negative direct immunofluorescence showed IgA deposits in the dermis. Sarcoidosis with cutaneous and hepatic involvement was established based on compatible clinical findings and supportive histology. The period between manifestations of Duhring disease and skin manifestations of sarcoidosis was 20 years. Conclusion: Our clinical case supports the hypothesis for common immune pathogenic factors in gluten-sensitive diseases and sarcoidosis. The simultaneous occurrence of celiac disease and sarcoidosis is rare, but should not be under recognized.

    Full Text Available Chronic granulomatous disease (CGD is a rare, polygenic primary immunodeficiency. In this case report, we describe a previously healthy 13-year-old boy who presented with multifocal pulmonary aspergillosis and was subsequently diagnosed with an autosomal recessive form of chronic granulomatous disease. CGD has a variable natural history and age of presentation and should be considered when investigating a patient with recurrent or severe infections with catalase-positive organisms.

    Science.gov (United States)

    Studdy, P; Bird; James, D G; Sherlock, S

    Serum angiotensin-converting enzyme (SACE) activity was significantly higher in 90 patients with sarcoidosis (55 +/- [S.D.] 23 nmol min-1 ml-1) than in 80 healthy controls (34 +/- 9 nmol min-1 ml-1). Steroid therapy modified SACE activity; 60 sarcoidosis patients who were not being treated with steroids had significantly higher enzyme activities (58 +/- 24 nmol min-1 ml-1) than 30 steroid-treated sarcoidosis patients (40 +/- 19 nmol min-1 ml-1). In 50% of the non-steroid treated sarcoidosis patients SACE activity was more than than 2 S.D. above the mean value for the controls. SACE activity was measured in 22 tuberculous patients (38 +/- 14 nmol min-1 ml-1), 20 leprosy patients (34 +/- 9 nmol min-1 ml-1), 31 with primary biliary cirrhosis (44 +/- 20 nmol min-1 ml-1), 26 with inflammatory bowel disease (31 +/- 9 nmol min-1 ml-1), eight with hepatic granulomatous disease, five with Hodgkin's disease, and two with schistosomiasis. The combined false-positive rate for these non-sarcoidosis patients was 10%. Serial SACE assays provide useful information on the course of sarcoidosis and response to steroid treatment.

  6. Etiologic Aspect of Sarcoidosis as an Allergic Endogenous Infection Caused by Propionibacterium acnes

    Directory of Open Access Journals (Sweden)

    Yoshinobu Eishi

    2013-01-01

    Full Text Available Sarcoidosis is a systemic granulomatous disease of unknown etiology. Propionibacterium acnes is the only microorganism that has been isolated from sarcoid lesions. Many P. acnes have been detected in sarcoid lymph nodes using quantitative PCR and in sarcoid granulomas by in situ hybridization. P. acnes trigger factor protein causes a cellular immune response only in sarcoid patients and induces pulmonary granulomas in mice sensitized with the protein and adjuvant, but only those with latent P. acnes infection in their lungs. Eradication of P. acnes by antibiotics prevents the development of granulomas in this experimental model. Although P. acnes is the most common commensal bacterium in the lungs and lymph nodes, P. acnes-specific antibody detected the bacterium within sarcoid granulomas of these organs. P. acnes can cause latent infection in the lung and lymph node and persist in a cell-wall-deficient form. The dormant form is activated endogenously under certain conditions and proliferates at the site of latent infection. In patients with P. acnes hypersensitivity, granulomatous inflammation is triggered by intracellular proliferation of the bacterium. Proliferating bacteria may escape granulomatous isolation, spreading to other organs. Latent P. acnes infection in systemic organs can be reactivated by another triggering event, leading to systemic sarcoidosis.

    2015-01-01

    Full Text Available Introduction. The splenic involvement is common in sarcoidosis, but its real frequency is still obscure, depending doubtless on the method of splenomegaly detection. Splenomegaly may be accompanied with pain or anemia, leucopenia and thrombocytopenia. Objective. The aim of this study was to investigate the frequency of splenomegaly related to clinical characteristics of sarcoidosis and to solve the dilemma - whether to introduce medicaments, and when to perform splenectomy. Methods. The method of the study is a retrospective and prospective analysis of the patients’ material. Results. The study included 540 patients with sarcoidosis in a 20-year period. Of them, 26% had splenomegaly detected by computerized tomography screening. Splenomegaly was more frequently registered in the patients with a longer history of sarcoidosis (38%, as compared to those with a shorter history of the disease (23% (p<0.05. Splenomegaly was more frequently registered in the patients with other extrapulmonary lesions detected (33% than in those who had no extrapulmonary manifestations of sarcoidosis (17% (p<0.01. Indications, possible benefits and complications of splenectomy were analysed in 11 sarcoidosis patients undergoing this intervention for various reasons, of which the follow-up period ranged from one to 20 years. Conclusion. Splenomegaly was more frequent in chronic cases or in the patients with established sarcoid lesions of other extrapulmonary organs. The primary treatment of uncomplicated symptomatic splenic sarcoidosis includes medicamentous therapy. Occasionally, splenectomy is required. Prognostically, splenomegaly indicates an unfavorable course of the disease.

    2018-03-27

    Sarcoidosis is a generalised granulomatous disorder of unknown aetiology. Cardiac involvement may affect conduction system, myocardium, valvular apparatus and pericardium. Clinical spectrum ranges from asymptomatic involvement to sudden cardiac death. Patients with biopsy-proven extracardiac sarcoidosis should be screened for cardiac involvement (standard ECG, 24-hour Holter ECG, echocardiography) and in case of any abnormalities found on these tests, more advanced diagnostic methods should be used. Steroid treatment is still the mainstay of therapy in cardiac sarcoidosis. Several immunosuppresive agents are also effective and used in different combinations with steroids, as well as heart failure treatment (including ACE inhibitors, angiotensin receptor blockers, beta-blockers and diuretics). Advanced heart block requires pacemaker implantation, and implantable cardioverterdefibrillator is an effective treatment in primary and secondary prophylaxis of sudden cardiac death. Heart transplantation is considered in advanced, drug-resistant heart failure or incessant ventricular arrhythmias unresponsive to other forms of therapy. © 2018 MEDPRESS.

    2014-10-20

    We undertook a study on a series of laryngeal sarcoidosis (LS), a very rare and often threatening localization to better specify laryngeal manifestations, sarcoidosis clinical expression and long-term follow-up. This was a retrospective case-control study. All LS patients from two French centers were included and compared to sarcoidosis patients without laryngeal localization with two controls for one patient. Twelve consecutive LS patients were recruited between 1993 and 2011. LS revealed sarcoidosis in eight cases (67%). The most common symptoms were hoarseness (77%), inspiratory dyspnea (38%) and dysphagia (38%). Epidemiological characterisics were not different. Extrapulmonary localizations were significantly more common in LS patients than in controls (92% vs. 54%, p=0.02), particularly lupus pernio (25% vs. 0%, p=0.03) and nasosinusal involvement (83% vs. 4%, p<0.01) while thoracic involvement was less frequent (58% vs 100%, p < 0.01). Treatment rates were higher in the LS group (92% vs. 58%, p=0.04), and treatment duration was longer (median: 81 vs. 13 months, p=0.04), with frequent long-term treatment (67%, N=8/12). Two patients underwent surgery. One patient needed temporary tracheostomy during the course of the disease; Remission rates were lower in LS patients (9% vs. 58% at 2 years p<0.01). Eventually, there was no death nor definitive tracheotomy. LS is a rare condition that is often associated to other loco-regional localizations. LS are often difficult to manage. Survival is good but may require a medico-surgical approach.

    To summarize the clinical features and the diagnosis-treatment points of sarcoidosis related pleural effusion. Six typical sarcoidosis related pleural effusion cases with pathological evidence were reviewed, and the clinical data of these cases were retrospectively analyzed and the related literatures were reviewed. The literature review was carried out respectively with "sarcoidosis", "pleural disease" and "pleural effusion" as the keywords in CNKI and PubMed database by January 2014. Six cases, including 1 male and 5 females, with sarcoidosis related pleural effusions were reported. 3 cases had bilateral effusions, 2 cases had left effusion and 1 case had right effusion. The pleural effusion routine test had a low specificity, which demonstrated that the fluid was exudate and consisted with large number of lymphocytes. 3 of these cases were diagnosed by medical thoracoscopy. Medical thoracoscopy revealed that pleural involvement was variable with multiple nodulespresent in some cases and subtle change in others. A total of 28 literatures and 92 cases with pleural involvement in sarcoidosis were retrieved from CNKI and PubMed database (time range: 2004.1-2014.1), including 59 cases of pleural effusion, 29 cases of pleural thickening, 3 cases of pneumothorax and 1 case of nodules in pleura. Pleural involvement in sarcoidosis was often misdiagnosed or mistreated as tuberculous pleurisy because the routine tests regarding pleural effusion usually had a low specificity. Medical thoracoscopy could provide clinicians with important clues to assist differentiation of the cause for non-conclusive pleural effusion in this situation.

    2008-01-01

    Sarcoidosis is a systemic disease that histologically typically shows non-caseating granulomas. The most common radiologic finding is hilar and mediastinal adenopathy. Patients with widely disseminated disease may show involvement of the peripheral appendicular skeleton in 1-13% of such cases. A primary skeletal presentation without other manifestations typical of the disease is rare. We present a case of sarcoidosis in a middle-aged Caucasian man in whom the disease presented with widespread lytic lesions in the axial skeleton and long bones, mimicking metastatic disease. There was no involvement of the peripheral skeleton, skin or lungs. (orig.)

    2007-09-01

    Studies of serum angiotensin converting enzyme (SACE) activity and its association with ACE gene insertion/deletion (I/D) polymorphism in relation to sarcoidosis have yielded variable results. This has been attributed to possible ethnic differences. Present study was designed to evaluate the relationship between I/D polymorphism and susceptibility to develop sarcoidosis and its effect on SACE activity and disease course in Asian Indian patients with sarcoidosis. ACE genotyping was performed in 72 consecutive patients with sarcoidosis and 199 controls (96 normal healthy individuals and 103 tuberculosis patients taken as disease controls). SACE activity was determined in all patients with sarcoidosis. Various parameters were compared amongst patients with different genotypes as well as between sarcoidosis and control groups. Gene frequency of I and D in control group was 0.6 and 0.4, whereas in patients with sarcoidosis it was 0.35 and 0.65 respectively (p SACE activity was highest in patients with DD genotype and followed an order of DD > ID > II. Good response to initial corticosteroids was seen in 6 of 6 (100%) patients with II genotype whereas in only 32 of 37 (84%) with ID and 16 of 25 (64%) with DD (p = 0.013). In Asian Indian population 'D' allele is associated with an increased risk for development of sarcoidosis and patients with 'D' allele show poor response to corticosteroids.

    1991-01-01

    The contribution of pulmonary nuclear medicine was evaluated in 115 patients with interstitial pulmonary diseases (IPD). Ventilation study (V) with 81m Kr or 133 Xe, distribution of compliance in thoraco-pulmonary system (C) by 81m Kr gas bolus inhalation method, perfusion study (Q) with 99m Tc-MAA, 67 Ga scintigraphy and an assessment of pulmonary epithelial permeability with 99m Tc-DTPA aerosol were performed as nuclear medicine procedures. Pulmonary function test (%DLco, vital capacity, and functional residual capacity) and blood gas analysis were also examined. Abnormalities in V were larger than that in Q, which was high V/Q mismatch finding, in interstitial pneumonia. Correlation between V/Q mismatch and PaO 2 was, therefore, not significant. %DLco was decreased in cases with larger V/Q mismatches. 67 Ga accumulated in the early stage of interstitial pneumonia when CT or chest X-ray did not show any finding. %DLco was decreased in cases with strong accumulation of 67 Ga. 67 Ga might be useful to evaluate activity of the disease. Pulmonary epithelial permeability was assessed by 99m Tc-DTPA inhalation study. This permeability became accelerated in idiopathic interstitial fibrosis and sarcoidosis. Pulmonary epithelial permeability may be useful as an indicator for epithelial cell injury. (author)

    2013-01-01

    Full Text Available Abstract Sarcoidosis is a granulomatous multisystem disorder of unclear etiology that involves any organ, most commonly the lung and the lymph nodes. It is hypothesized that the disease derives from the interaction between single or multiple environmental factors and genetically determined host factors. Multiple potential etiologic agents for sarcoidosis have been proposed without any definitive demonstration of causality. We report the case of two patients, husband (57 years old and wife (55 years old, both suffering from sarcoidosis. They underwent a lymph node biopsy by mediastinoscopy which showed a “granulomatous epithelioid giant cell non-necrotising chronic lymphadenitis”. They had lived up to 3 years ago in the country in a farm, in contact with organic dusts, animals such as dogs, chickens, rabbits, pigeons; now they have lived since about 3 years in an urban area where there are numerous chemical industries and stone quarries. The aim of this case report was to focus on environmental factors that might be related to the pathogenesis of the sarcoidosis.

    2011-02-01

    Full Text Available Abstract Introduction Takayasu arteritis (TA is a chronic vasculitis of unknown origin, affecting mainly the aorta and its main branches. As a result of the inflammation, stenosis, occlusion or dilatation of the involved vessels may occur and cause a wide range of symptoms. It has been described in association with various auto-immune disorders (mainly inflammatory digestive tract diseases. However, only few cases of TA associated with sarcoidosis have been reported, raising the question of an association by chance. Case report We report a case of a 34 year-old woman, with one year history of sarcoidosis, who presented with asymmetric high hypertension revealing inflammatory humeral, axillary and subclavian arteritis related to TA, successfully treated by steroid and immunosuppressive therapy(MethotrexateR. Conclusion TA and sarcoidosis may be related, rising the hypothesis that TA or Takayasu arteritis-like granulomatous vasculitis may be, in fact, a complication of sarcoidosis.

  1. A case of muscular sarcoidosis diagnosed by gallium-67 scintigraphy and magnetic resonance imaging

    Sohn, Hyung Sun; Kim, Euy Neyng

    1999-01-01

    Gallium-67 scintigraphy is helpful in the assessment of active extrapulmonary sarcoidosis. Muscular involvement of sarcoidosis is often asymptomatic or nonspecific, and laboratory examinations do not provide convincing evidence of muscular involvement. We report a case of muscular sarcoidosis, which was detected by gallium-67 scintigraphy. In a patient who was suffering from fever and arthalgia of knee joint, gallium-67 scintigraphy showed mediastinal and hilar involvement of sarcoidosis with unexpected extensive muscular uptake. Magnetic resonance imaging revealed the detailed depiction of intramuscular infiltration of sarcoid granuloma. Gallium-67 scintigraphy is useful in detecting inflammatory muscular involvement of sarcoidosis as well as other multiorgan involvement

    The value of high-resolution computed tomography (HRCT) in diagnosing and assessing inflammatory activity in sarcoidosis is well established. The aim of the present study was to address the intra- and inter-observer agreements of the HRCT score by Oberstein et al. [8], and to evaluate the relationship between HRCT findings and disease severity expressed in respiratory functional impairment in sarcoidosis. The clinical records of 80 known sarcoidosis patients visiting the outpatient clinic between January 2000 and August 2001, who underwent a HRCT as well as lung function tests (including exercise testing), were reviewed. Two readers scored the first 60 HRCT images twice. Weighted kappa and intra-class correlation coefficient were used to assess the reliability of the HRCT scoring system. Spearman's rank correlation coefficients and multiple regression analyses were performed to evaluate the relationship between HRCT findings (first reading, reader A) and respiratory functional impairment. Intra- and inter-reader reliability demonstrated good agreement. All HRCT subscores, except enlargement of lymph nodes, were correlated to the FEV{sub 1}, FVC, DLco, Pao{sub 2}max (all p<0.05) and A-aPo{sub 2}max (p <0.001). Furthermore, HRCT abnormalities, but not the chest radiographic stage, were strongly associated with functional parameters. Abnormal changes of lung parenchyma, established by HRCT features, were associated with respiratory functional impairment in sarcoidosis. Moreover, compared with the radiographic stages, HRCT findings appeared to be much more sensitive in depicting respiratory disability, especially abnormal gas exchange. (orig.)

    Full Text Available Sarcoidosis is a chronic disease characterised by the development and accumulation of granulomas in multiple organs. We report two observations of disseminated Mycobacterium genavense infection in patients with proven sarcoidosis. High fever and abdominal pain appeared at 8 and 18 months following the initiation of immunosuppressive therapy. Abdominal computed tomography scans of the patients showed diffuse mesenteric lymphadenitis and splenomegaly. The diagnosis was obtained on bone marrow specimens for both patients with numerous acid-fast bacteria at direct examination and positive specific mycobacterial identification by nucleic acid amplification test. Despite prompt antimycobacterial therapy, occurrence of complications (peritonitis post-splenectomy surgery and lung carcinoma resulted in a fatal outcome for both patients. These cases highlight that opportunistic infections like M. genavense or other nontuberculous mycobacterial infections should be considered for long-standing immunocompromised patients with sarcoidosis.

    Full Text Available Introduction: Pulmonary fungus ball is a rare complication in pre-existing pulmonary cavitary lesions, due to some chronic pulmonary diseases including tuberculosis, lung abscess and sarcoidosis. Fungus ball is mostly caused by aspergillus. In many patients, fungus ball is asymptomatic, but in a significant number of them it can develop cough and hemoptysis, which may be massive and fatal. The cornerstone of assessment is chest imaging, along with sputum culture or aspergillus antibody in patient's serum. The purpose of this report is increment in attention to this complication in patients with previous pulmonary tuberculosis (TB. Case Presentation: The patient was a 23-year-old woman with chief complaint of fever, cough and hemoptysis, who was hospitalized in the Infectious Diseases Ward of Farshchian Sina hospital in March 2016. She had a history of anti-TB therapy from two years before. Sputum and bronchoalveolar lavage (BAL were negative for cytology and Mycobacterium tuberculosis, but cultures of both samples were positive for Aspergillus niger. Her lung contrast-enhanced computerized tomography (CECT scan revealed the presence of a fungus ball inside the upper lobe cavity of right lung. After lobectomy, fungal mass was confirmed by histopathology. Conclusions: In patients with pulmonary complaints (especially hemoptysis and history of cavitary pulmonary tuberculosis, the differential diagnosis of community-acquired pneumonia, lung abscess, reactivation of tuberculosis and lung cancer as well as fungal infections should be considered.

    Full Text Available Background: Sarcoidosis is a systemic granulomatous disease of unknown etiology. Epidemiological studies of different populations are essential because clinical presentation, organ involvement, disease severity, and prognosis vary significantly according to region and population. The aim of this study was to assess epidemiological and clinical characteristics, staging factors, and clinical course in patients with sarcoidosis from a tertiary hospital in Oporto, Portugal. Methods: A retrospective analysis of patients with sarcoidosis and at least 2 years of follow-up evaluated at the Centro Hospitalar de São João between 2000 and 2014. Results: We identified 409 patients with sarcoidosis (females, 58.9%; mean age at diagnosis, 38.9 ± 13.4 years; smokers, 14.4%]. All the patients were diagnosed according to the ERS/ATS/WASOG consensus statement and 64.1% had evidence of noncaseating epithelioid cell granulomas in biopsy specimens. Bronchoalveolar lavage was performed as part of the diagnostic work-up in 289 patients and 90.2% had lymphocytosis (CD4/CD8 ratio ≥ 3.5 in 60.9% of cases. Exertion dyspnea, cough, and constitutional symptoms were the most common presenting symptoms; 10.1% of patients were asymptomatic, 22.8% had Löfgren syndrome, and 50.5% had extrathoracic involvement. Radiographic stages of disease according to the Scadding criteria were as follows: stage 0 (5.2%, stage I (33.7%, stage II (47.0%, stage III (8.4%, and stage IV (5.7%. Impaired respiratory function was observed in 45.6% patients and was mostly mild. Systemic treatment was administered in 58.6% of cases. Overall, 45.3% of patients experienced disease resolution. Conclusion: The epidemiological and clinical characteristics of this cohort of patients with sarcoidosis from the Oporto region in northern Portugal revealed epidemiological and clinical characteristics that were generally similar to those described in other Western Europe populations and

  7. Rare association of thymoma, myasthenia gravis and sarcoidosis : a case report

    Full Text Available Abstract Introduction The association of thymoma with myasthenia gravis (MG is well known. Thymoma with sarcoidosis however, is very rare. We presented an interesting case with coexisting thymoma, MG and sarcoidosis. Case presentation A 59-year-old female patient with a history of sarcoidosis was admitted to the hospital with a one-day history of sudden onset of right-sided partial ptosis and diplopia. Neurosarcoidosis with cranial nerve involvement was considered, but was ruled out by the clinical findings, and MG was confirmed by the positive tensilon test, electrophysiological findings and positive acetylcholine receptor binding antibodies. On further evaluation, a CT chest scan showed a left anterior mediastinal mass and bilateral lymphadenopathy. Post surgical diagnosis confirmed the thymoma and sarcoidosis in the lymph nodes. Conclusion When two or more diseases of undetermined origin are found together, several interesting questions are raised. It is important to first confirm the diagnoses individually. Immunologic mechanisms triggering the occurrence of these diagnoses together, are difficult to address. Although the coexistence of thymoma, MG and sarcoidosis may be coincidental, it is noteworthy to report this case because of the multiple interesting features observed as well as the rarity of occurrence.

    Full Text Available Aim: To review a general hospital′s experience with sarcoidosis and the clinical pattern of the disease among Saudis. Methods: A retrospective file review was carried out on all patients with a proven diagnosis of sarcoidosis in a general hospital in Eastern Saudi Arabia over a period of 11 years (1998-2008. Results: Sixty-nine patients, of whom 33 cases were included in the analyses, were diagnosed to have sarcoidosis during the study period. There were 18 females and 15 males. The mean age was 44.5 years (SD 17. The most common presentations were cough (48%, dyspnea (21%, joint pain (18%, splenomegaly (12%, hepatomegaly (9%, and lymphadenopathy (5%. The biochemical analysis showed elevated calcium levels in 6% and elevated angiotensin converting enzyme (ACE in 14 (46.7%. The tuberculin skin test was negative in all tested patients (n = 29 except one patient. The patients were classified using the modified Scadding classification system. None of the patients was in stage 0, 39.4% were in stage 1, 45% were in stage 2 and 15% were in stage 3.. The diagnosis in all patients was proven histologically. The outcome was favorable in most patients (85%, and in 6% of the patients, the course was chronic and progressive, although 66% received active treatment. Conclusion: Sarcoidosis does occur in native Saudis. The clinical presentation of these patients was similar to the western pattern of disease with some differences such as relative lack of cardiac, eye, parotid, and central nervous system involvement. The rarity of cardiac and central nervous system involvement was comparable with other Middle Eastern studies. Sarcoidosis, though rare in our community, should still be considered in the differential diagnosis of patients with the typical presentation after excluding tuberculosis.

    We present a highly unusual and interesting case of coexistent hyperparathyroidism and sarcoidosis leading to hypercalcaemia. A 70 year old female presented with weight loss, constipation and dehydration. Investigations revealed marked hypercalcaemia with a non-suppressed PTH. In view of the degree of hypercalcaemia as well as the unintentional weight loss, investigations for malignancy were conducted -these were negative. Parathyroid imaging was then requested and an adenoma was identified. Surprisingly, surgery revealed the coexistence of a parathyroid adenoma with the unexpected finding of sarcoid granulomas within the parathyroid and thyroid glands. To our knowledge, this is the first such case reported. Further imaging confirmed pulmonary sarcoidosis and a serum ACE was elevated. Serum calcium levels did not respond to parathyroidectomy but eventually fell with steroid therapy.

    2011-11-01

    Full Text Available Sarcoidosis is a multisystem granulomatous disorder of unknown etiology and it may rarely be associated with a second disorder. Celiac disease is an immune-mediated enteropathy characterized with malabsorption caused by gluten intolerance, and several reports indicate an association between celiac disease and sarcoidosis. In addition, although celiac disease is associated with several extraintestinal pathologies, venous thrombosis has been rarely reported. Herein we present a rare case report of a patient with a diagnosis of sarcoidosis, celiac disease and deep venous thrombosis because of the rare association of these disorders. The patient was admitted with abdominal pain, weight loss, chronic diarrhea and a 5-day history of swelling in her right leg. A diagnosis of deep venous thrombosis was achieved by doppler ultrasonographic examination. The diagnosis of celiac disease was made by biopsy of duodenal mucosa and supported with elevated serum level of anti-gliadin IgA and IgG, and a diagnosis of sarcoidosis was achieved by transbronchial needle aspiration from the subcarinal lymph node during flexible bronchoscopy.

    Ventilatory steady state measurement with Xe-133 were performed to evaluate regional ventilation (V radical) and perfusion (Q radical) in 60 cases of primary lung cancer and 39 cases of pulmonary diseases-chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, sarcoidosis, mitral stenosis with pulmonary hypertension (PH), pulmonary alveolar proteinosis, bronchial adenoma and pulmonary embolism. Of 60 cases of lung cancer, 11 cases showed V radicalQ radical mismatch (18%). Even in the V radicalQ radical matched defect cases, a different grade of disorder was seen in V radical and Q radical and the grade of Q radical was severer than the grade of V radical. Of 38 cases irradiated by Linac X-ray, 3 cases whose V radical, Q radical were disordered a little before irradiation recovered completely to normal range after irradiadiation. Of 38 cases subjected to radiation therapy, radiation injury of lung was recognized in 22 cases. In the cases of recovered V radical, Q radical after irradiation, radiation injury of lung occurred, and then V radical, Q radical disordered and returned to pre-irradiation value. In the cases that recovered little in V radical, Q radical, radiation injury of lung occurred, and then V radical, Q radical could not return to pre-irradiation value. In 39 cases of pulmonary diseases, 7 cases of sarcoidosis showed normal V radical and Q radical value. 13 cases of COPD was available to evaluate the regional pulmonary function in MTT (Mean Transit Time). V radical, Q radical were slightly disordered and MTT proloned slightly in 10 cases of diffuse pulmonary fibrosis where a marked fibrosis lesion was remarkable. Six cases of PH showed significant correlation between the left ventricular mean pressure and the perfusion ratio of upper and lower lung field. (J.P.N.).

    2015-04-01

    Full Text Available Sarcoidosis is a granulomatous inflammatory disease, diagnosed through tissue biopsy of involved organs in the absence of other causes such as tuberculosis (TB. No specific serologic test is available to diagnose and differentiate sarcoidosis from TB. Using a high throughput method, we developed a T7 phage display cDNA library derived from mRNA isolated from bronchoalveolar lavage (BAL cells and leukocytes of sarcoidosis patients. This complex cDNA library was biopanned to obtain 1152 potential sarcoidosis antigens and a microarray was constructed to immunoscreen two different sets of sera from healthy controls and sarcoidosis. Meta-analysis identified 259 discriminating sarcoidosis antigens, and multivariate analysis identified 32 antigens with a sensitivity of 89% and a specificity of 83% to classify sarcoidosis from healthy controls. Additionally, interrogating the same microarray platform with sera from subjects with TB, we identified 50 clones that distinguish between TB, sarcoidosis and healthy controls. The top 10 sarcoidosis and TB specific clones were sequenced and homologies were searched in the public database revealing unique epitopes and mimotopes in each group. Here, we show for the first time that immunoscreenings of a library derived from sarcoidosis tissue differentiates between sarcoidosis and tuberculosis antigens. These novel biomarkers can improve diagnosis of sarcoidosis and TB, and may aid to develop or evaluate a TB vaccine.

    Sarcoidosis is endemically prevalent in Northern Europe, but gender differences among the sarcoidosis population have not yet been compositely addressed. To reveal independent factors that formulate gender differences in the presentation of sarcoidosis. All Caucasian patients with confirmed sarcoidosis were recruited from the outpatient department of the Lung Clinic of the Tartu University Hospital, Estonia, between February 2009 and April 2011. Data on demographics, complaints, symptoms, clinical presentation, extrapulmonary manifestations, radiographic stage, lung function parameters and sarcoidosis-related laboratory indices were all drawn from patients' clinical records at presentation. Factors characteristic of female gender were estimated using multivariate logistic regression analysis. Of 230 cases included, there were significantly more females (56.5%, P = 0.005). After adjustment for age, females appeared distinguishable from males by older age [adjusted odds ratio (OR) 1.04, 95% confidence interval (CI) 1.02-1.07], less frequent smoking (OR 0.25, 95% CI 0.13-0.49), higher probability of extrapulmonary complaints (OR 2.06, 95% CI 1.16-3.65) and musculoskeletal sarcoidosis (OR 3.22, 95% CI 1.65-6.29), and after adjustment for both age and smoking status lower forced expiratory volume in 1 s and lung carbon monoxide diffusing coefficient % predicted (OR 0.89, 95% CI 0.82-0.97 and OR 0.98, 95% CI 0.96-0.995, respectively), but by higher forced vital capacity % predicted (OR 1.12, 95% CI 1.03-1.22). Women with sarcoidosis are independently characterized by greater airflow obstruction, lower lung diffusing coefficient, older age, less smoking, and more frequent extrapulmonary complaints and musculoskeletal involvement. This may urge special attention when addressing female patients in both differential diagnostic and management settings. © 2014 John Wiley & Sons Ltd.

    We report the first observation of clinical manifestations of vena cava superior syndrome (VCSS) associated with sarcoidosis. Twenty-four years after the first signs of the disease had been noted, mediastinal lymphomas penetrating the wall of the vena cava superior caused complete obstruction. It is most unusual for the vessel wall to be destroyed in this way, which explains why VCSS is often missed in sarcoidosis. The obstructed vessel was resected and successfully replaced by a Gore-Tex prosthesis. The importance of VCSS for the differential diagnosis is pointed out. Two further peculiarities are the simultaneous occurrence of elevated intraocular pressure and VCSS, and the familial incidence. (orig.) [de

    Sarcoidosis is a multisystem disease, with extrathoracic involvement occurring in 25-50% of patients. Multi-organ involvement is often associated with a more chronic and severe course. The value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in diagnosing extrathoracic involvement in sarcoidosis has been demonstrated; however, because of the radiation dose and high cost, indications for its use must be well defined. Angiotensin-converting enzyme (ACE) is produced by active granuloma cells; thus, serum ACE (sACE) levels may reflect the total granuloma load. In this retrospective study, we evaluated the diagnostic value of sACE in the detection of extrathoracic involvement in sarcoidosis. 43 patients with biopsy-proven sarcoidosis underwent FDG-PET/CT during the initial workup. Positive findings were classified as thoracic and/or extrathoracic. The diagnostic value of sACE was estimated using sensitivity, specificity, and area under the receiver operating characteristic curves (AUCs). Of the 43 patients studied, 17 (39.7%) had extrathoracic involvement. In this group, sACE values were higher than in patients without extrathoracic involvement (331 vs. 150, p=0.002) and correlated positively with extrathoracic involvement (R:0.532 p=0.02). Receiver operator characteristic curve analysis revealed an AUC of 0.816 [95% confidence interval: 0.669-0.963, p=0.002], 70.6% sensitivity and 80% specificity at the sACE cut-off value. In sarcoidosis, extrathoracic involvement may be life threatening or indicative of poor outcome. sACE levels are easily determined and may predict extrathoracic involvement. In patients with sarcoidosis, sACE levels can be used to better define those who would benefit from FDG-PET/CT examination to detect extrathoracic involvement.

    Muscular involvement of sarcoidosis is rare and occurs in two forms:nodular and myopathic. In the nodular variety, lesions are long and extend along muscle fibers. Axial MR imaging reveals a star-shaped central structure of decreased signal intensity. Sagittal and coronal MR images show three stripes:an inner stripe of decreased signal intensity and outer stripes of increased signal intensity. Longitudinal sonography shows an echogenic inner stripe and hypoechoic outer stripes. We report a case of nodular- type muscular sarcoidosis in a 53-year-old man, describing the findings of MRI and ultrasonography

    Background: Sarcoidosis is a multisystem inflammatory disease of unknown origin with characterization of small granulomas. Angiotensin-converting enzyme (ACE) is a pathophysiologic marker of sarcoidosis. We present the ACE insertion/deletion (I/D) polymorphism in correlation with serum ACE level in Iranian patients with sarcoidosis. Methods: From Jan 2014 to Jan 2015, 102 Iranian patients who histopathologically diagnosed for sarcoidosis and 192 healthy age and sex-matched controls were recruited. PCR was used for detection of I/D polymorphism in ACE gene. Results: Frequency of II/ID/DD genotype in sarcoidosis disease was 17%, 35.5%, and 47.1%, respectively. The frequency of D allele was 0.65. A significant association between I/D genotypes and mean of sACE level was seen (DD=85.2±22.9, P<0.001). More frequent genotype in sarcoidosis patients was DD (47%), ID genotype (45.9%) was found more in controls. Logistic regression analysis adjusting age and sex showed that ID to II (OR=0.35, 95%CI=0.17–0.73, P=0.005) and DD to II (OR=2.11, 95%CI=0.98–4.54, P=0.05) could be considered as a predictor factor for the disease activity. No significant model for men in sarcoidosis group was seen, while women with II/ID were associated with a reduced risk for the disease. Conclusion: Although more regional studies with appropriate statistical scale must be done to provide a better diagnosis and prognostic tool for this disease, this study demonstrates that ID and DD genotype could be predictive factors for sarcoidosis.

    Pancreatic sarcoidosis is a rare variant of systemic sarcoidosis, with cases described in literature as recently as January 2010. We present here a case of pancreatic involvement with non-caseating granulomas discovered on laparotomy in a patient with a preoperative diagnosis of pancreatic carcinoma. Computer tomography scan without contrast revealed a well-marginated smooth-shaped tumor in the head of the pancreas morphologically consistent with malignancy. During Whipple procedure, the mass was found to be a large lymph node that contained numerous non-caseating granulomas. Radiologically and clinically, non-caseating granulomas of the pancreas are often misdiagnosed as malignant tumor.

    Sarcoidosis is a multisystemic granulomatous disease of unknown etiology that predominantly affects lungs and intrathoracic lymph nodes; in rare cases (approx. 10%), infiltration of the spleen and liver may be observed. In order to identify hepatosplenic infiltration, MRI/CT of the abdomen and different ultrasound techniques (PD US, US D) are usually performed. Contrast enhanced ultrasound (CEUS) is a new technique in this diagnostic algorithm, but the fact that this is a safe, accurate, and widely available method opens a new perspective for the detection of abdominal lesions in sarcoidosis. We report 2 cases of hepatosplenic sarcoidosis – a 41-year-old woman with splenic lesions and a 46-year-old man with liver infiltration. On the basis of these 2 cases we intended to show the diagnostic potential of contrast enhanced ultrasound for the recognition of focal lesions of the spleen and liver in patients suffering from sarcoidosis

    Cryptococcus neoformans is an infrequent cause of septic arthritis. Cryptococcal infections have been linked to sarcoidosis because of both inherent immunologic consequences of the disease and its typical immune modulating treatments. Cryptococcal infections should be suspected in patients with underlying immune deficiencies, and a high degree of vigilance should be exercised to avoid misdiagnosis, dissemination of infection, and meningitis.

    Full Text Available Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen. Renal histology revealed granulomatous interstitial nephritis with necrotizing vasculitis. Outcome was favorable after the institution of high dose corticosteroids along with cyclophosphamide. Renal involvement is rare in sarcoidosis. However, the diagnostic delay should be avoided to improve the outcome.

    Sarcoidosis is a multisystem disease with an unpredictable and sometimes fatal course while the underlying pathomechanism is still unclear. Reasons of the increasing hospitalization rate and mortality in the United States remain in dispute but incriminated are a number of distinct comorbidities and risk factors as well as the application of more aggressive therapeutic agents. Studies reflecting the recent development in central Europe are lacking. Our aim was to investigate the recent mortality and hospitalization rates as well as the underlying comorbidities of hospitalized sarcoidosis patients in Switzerland. In this longitudinal, nested case-control study, a nation-wide database provided by the Swiss Federal Office for Statistics enclosing every hospital entry covering the years 2002-2012 (n = 15,627,573) was analyzed. There were 8,385 cases with a diagnosis of sarcoidosis representing 0.054% (8,385 / 15,627,573) of all hospitalizations in Switzerland. These cases were compared with age- and sex-matched controls without the diagnosis of sarcoidosis. Hospitalization and mortality rates in Switzerland remained stable over the observed time period. Comorbidity analysis revealed that sarcoidosis patients had significantly higher medication-related comorbidities compared to matched controls, probably due to systemic corticosteroids and immunosuppressive therapy. Sarcoidosis patients were also more frequently re-hospitalized (median annual hospitalization rate 0.28 [IQR 0.15-0.65] vs. 0.19 [IQR 0.13-0.36] per year; p < 0.001), had a longer hospital stay (6 [IQR 2-13] vs. 4 [IQR 1-8] days; p < 0.001), had more comorbidities (4 [IQR 2-7] vs. 2 [IQR 1-5]; p < 0.001), and had a significantly higher in-hospital mortality (2.6% [95% CI 2.3%-2.9%] vs. 1.8% [95% CI 1.5%-2.1%] (p < 0.001). A worse outcome was observed among sarcoidosis patients having co-occurrence of associated respiratory diseases. Moreover, age was an important risk factor for re-hospitalization.

    Full Text Available Literature on concurrent association of sarcoidosis with lymphoproliferative malignancies other than lymphoma e.g. multiple myeloma is meager. The rarity of the situation prompted us to report this patient who was a 51-year-old woman with a 2-years history of breathlessness, cough with expectoration, chest pain and backache. Initial evaluation revealed mild anemia, increased alkaline phosphatase with chest skiagram showing both lower zone non homogenous opacities with calcified hilar lymph nodes. CECT chest showed mediastinal with bilateral hilar lymphadenopathy, parenchymal fibrosis, traction bronchiectasis, ground glass opacities, septal and peribronchovascular thickening affecting mid and lower lung zones bilaterally. MRI Dorsolumbar spine was suggestive of marrow infiltrative disorder. EBUS FNA of intrathoracic nodes, EBB and TBLB confirmed sarcoidosis. PET CT revealed hyper metabolic activity in lung, multiple lymph nodes and lytic bone lesions. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin IgG kappa type. Bone marrow biopsy revealed an increase in plasma cells (15%, but no granulomas. Diagnosis of Indolent or multiple myeloma with sarcoidosis was established. 12 cases of sarcoidosis and multiple myeloma have been reported in literature, and mostly preceding the onset of multiple myeloma by many years, in our case both were diagnosed concurrently.

    Sarcoidosis is a chronic disease with different phenotypic manifestations. Health-related quality of life is an important aspect in sarcoidosis, yet difficult to measure. The objective of this study was to identify clinical markers predictive of poor quality of life in sarcoidosis patients that can be followed over time and targeted for intervention. We assessed the quality of life of 162 patients with confirmed sarcoidosis in a prospective, cross-sectional study using the Sarcoidosis Health Questionnaire (SHQ) and Short Form-36 Health Survey (SF-36). We evaluated the validity of these questionnaires and sought to identify variables that would best explain the performance scores of the patients. On multivariate regression analyses, the very best composite model to predict total scores from both surveys was a model containing the distance-saturation product and Borg Dyspnea Scale score at the end of a 6-min walk test. This model could better predict SF-36 scores (R² = 0.33) than SHQ scores (R² = 0.24). Substitution of distanced walked in 6 min for the distance-saturation product in this model resulted in a lesser ability to predict both scores (R² = 0.26 for SF-36; R² = 0.22 for SHQ). Both the SHQ and SF-36 surveys are valuable tools in the assessment of health-related quality of life in sarcoidosis patients. The best model to predict quality of life among these patients, as determined by regression analyses, included the distance-saturation product and Borg score after the 6-min walk test. Both variables represent easily obtainable clinical parameters that can be followed over time and targeted for intervention.

    Serum angiotensin converting enzyme (SACE) is considered to reflect disease activity in sarcoidosis. SACE activity is increased in many patients with active sarcoid lesions. The mechanism for the increased SACE activity in this disease has not been clarified. ACE insertion/deletion (I/D) gene polymorphism has been reported to have an association with SACE levels in sarcoidosis, but no evidence of an association between angiotensin II receptor gene polymorphism and SACE in this disease has been found. A study of the association of angiotensin II receptor gene polymorphisms with sarcoidosis was therefore undertaken. ACE (I/D), angiotensin II type 1 receptor (AGTR1), and angiotensin II type 2 receptor (AGTR2) gene polymorphisms were investigated by polymerase chain reaction (PCR) and SACE levels were measured in three groups of patients: those with sarcoidosis or tuberculosis and normal controls. There was no difference in allele frequency of AGTR1 and AGTR2 polymorphism among the three groups. Neither AGTR1 nor AGTR2 polymorphisms were associated with sarcoidosis. SACE activity was higher in patients with sarcoidosis with the AGTR1 A/C genotype than in others. However, this tendency was not detected in patients with tuberculosis. The AGTR1 allele C is associated with high activity of SACE in patients with sarcoidosis. It is another predisposing factor for high levels of SACE in patients with sarcoidosis and is considered to be an independent factor from the ACE D allele for high levels of SACE in sarcoidosis. This fact could be one of the explanations for the increased SACE activity in sarcoidosis.

    Full Text Available Abstract Introduction Although the causes of sarcoidosis are still unknown, past and current studies have provided evidence that this disease may be associated with occupational exposure to specific environmental agents. We describe a case of sarcoidosis in a dental surgeon with long exposure to inorganic dusts. To the best of our knowledge, this is the first report of this kind in the literature. Case presentation At the beginning of 2000, a 52-year-old Caucasian man, who worked as a dental surgeon, presented with shortness of breath during exercise, cough and retrosternal pain. After diagnosis of sarcoidosis, a scanning electronic microscopy with X-ray microanalysis of biopsy specimens was used in order to determine whether the disease could be traced to an occupational environmental agent. Results showed the presence of inorganic dust particles within sarcoidotic granulomas, and demonstrated that the material detected was identical to that found in a powder used by our patient for several years. Conclusions Although these results cannot be considered as definitive proof, they do however provide strong evidence that this disease may be associated with material used by dental surgeons.

    Vertebral involvement in sarcoidosis is rare and its clinical and imaging features are non-specific. Indeed, because the lesions are hard to differentiate from metastatic disease based on imaging alone, a histological confirmation is advised. Fatty replacement is a well-known finding indicating stabilization and healing in both benign and malignant conditions. It can be used as an indicator of a favorable disease course and response to treatment. We report the case of a 43-year-old woman with multifocal vertebral sarcoidosis lesions and long-term follow-up showing progressive and gradual fatty involution on magnetic resonance imaging (MRI) during 4 years of steroid treatment with a final favorable outcome.

    2000-01-01

    Objective: To investigate CT appearances of the normal and abnormal bronchovesicular bundles (BVB) and their corresponding pathologic basis, and to evaluate the role of these findings in diagnosing diffuse lung diseases. Methods: 6 fresh lungs obtained at autopsy and 8 surgical lung lobe specimens were studied. All lung specimens were inflated and fixed by Heitzman's method. HRCT with 10 mm thickness slice soft X-ray radiography was performed and HRCT-pathologic correlation was done. HRCT images of 100 cases with diffuse pulmonary disease were analyzed. Results: Thickened BVB with coarse margin and distorted structure correlated pathologically with peri-bronchovesicular pulmonary parenchyma inflammation and fibrosis, as well as peri-bronchovesicular interstitial disorder. Abnormalities of centrilobular BVB were recognizable by an increase in prominence of centrilobular structure on HRCT. In pathology, there were centrilobular peri-bronchovesicular dust induced granuloma in coal-miner's pneumoconiosis and centrilobular lymphangitis dilatation and filling with tumor cell in lymphangitis carcinomatosis. Increased centrilobular branching structure correlated pathologically with the presence of dilate intra-lobular bronchioles, inflammatory bronchiolar wall thickening, intraluminal secretions, and peri-bronchiolar inflammation. In 80 patients with predominant pulmonary interstitial diseases, thickened BVB with coarse margin or distortion were common in patients with pulmonary fibrosis. Nodular bronchovesicular bundle thickening were seen in sarcoidosis, lymphangitis carcinomatosis, and lymphoma. These were demonstrated in 8 of 20 sarcoidosis, 6 of 8 lymphangitis carcinomatosis , 3 of 5 lymphoma, and 2 of 15 coal-miner's pneumoconiosis. Increased centrilobular branching structures were seen in 14 of 20 patients with predominant bronchial diseases. Conclusion: Authors can limit the differential diagnostic range of diffuse lung diseases according to the appearances of BVB

    The contribution of pulmonary nuclear medicine was evaluated in 115 patients with interstitial pulmonary diseases (IPD). Ventilation study (V) with {sup 81m}Kr or {sup 133}Xe, distribution of compliance in thoraco-pulmonary system (C) by {sup 81m}Kr gas bolus inhalation method, perfusion study (Q) with {sup 99m}Tc-MAA, {sup 67}Ga scintigraphy and an assessment of pulmonary epithelial permeability with {sup 99m}Tc-DTPA aerosol were performed as nuclear medicine procedures. Pulmonary function test (%DLco, vital capacity, and functional residual capacity) and blood gas analysis were also examined. Abnormalities in V were larger than that in Q, which was high V/Q mismatch finding, in interstitial pneumonia. Correlation between V/Q mismatch and PaO{sub 2} was, therefore, not significant. %DLco was decreased in cases with larger V/Q mismatches. {sup 67}Ga accumulated in the early stage of interstitial pneumonia when CT or chest X-ray did not show any finding. %DLco was decreased in cases with strong accumulation of {sup 67}Ga. {sup 67}Ga might be useful to evaluate activity of the disease. Pulmonary epithelial permeability was assessed by {sup 99m}Tc-DTPA inhalation study. This permeability became accelerated in idiopathic interstitial fibrosis and sarcoidosis. Pulmonary epithelial permeability may be useful as an indicator for epithelial cell injury. (author).

  18. Cutaneous sarcoidosis in a patient with severe asthma treated with omalizumab

    2015-01-01

    Omalizumab, a monoclonal anti-immunoglobulin E antibody, has been used as an effective treatment for severe asthma associated with atopy over the past decade. Sarcoidosis is an idiopathic granulomatous disorder in which first-line treatment is usually glucocorticoids. To the authors’ knowledge, the present report describes the first case of an association between omalizumab therapy and revelation of cutaneous sarcoidosis with the withdrawal of systemic glucocorticoids. A 56-year-old woman with severe allergic asthma dependent on oral prednisone initiated omalizumab treatment. As her symptoms of asthma improved over the course of a year, her prednisone was gradually tapered. After being off glucocorticoids, she developed skin nodules that had biopsy characteristics of sarcoidosis. The present case illustrates the need to monitor closely for potential unmasking of glucocorticoid-responsive conditions when transitioning from systemic glucocorticoids to omalizumab therapy.

    Sarcoidosis is, from historical data, suggested to be more prevalent among patients with tattoo reactions. We aimed to evaluate this association in a systematic study. This is a consecutive study of patients with tattoo complications, diagnosed in the "Tattoo Clinic" at Bispebjerg University Hospital in Copenhagen, Denmark, from 2008 to 2015, based on clinical assessment and histology. From the overall group of 494 tattoo complications in 406 patients, 92 reactions in 72 patients showed a papulo-nodular pattern studied for local and systemic sarcoidosis, since sarcoidosis is expected to be nodular. Of the 92 reactions with a papulo-nodular pattern, 27 (29%) reactions in 19 patients were diagnosed as cutaneous or systemic sarcoidosis, supported by histology; 65 (71%) were diagnosed as non-sarcoidosis due to histology and no clinical sarcoid manifestations. "Rush phenomenon" with concomitant reaction in many other black tattoos, triggered by a recent tattoo with a papulo-nodular reaction, was observed in 70% in the sarcoidosis group and 28% in the non-sarcoidosis group, indicating a predisposing factor which may be autoimmune and linked with sarcoidosis. Agglomerates of black pigment forming foreign bodies may in the predisposed individual trigger widespread reaction in the skin and internal organs. Black tattoos with papulo-nodular reactions should be seen as markers of sarcoidosis. Papulo-nodular reactions may, as triggers, induce widespread reactions in other black tattoos - a "rush phenomenon" - depending on individual predisposition. Sarcoidosis is estimated to be 500-fold increased in papulo-nodular reactions compared to the prevalence in the general population, and the association with black tattoos is strong. © 2017 S.

    Serum angiotensin converting enzyme (SACE) concentration is considered a marker of sarcoidosis activity. This concentration is influenced by an insertion/deletion (I/D) polymorphism of the ACE gene, such that SACE levels follow the pattern DD>ID>II. The aim of our work was to study the relationship between I/D polymorphism and susceptibility to sarcoidosis, as well as the relation between this polymorphism and the clinical presentation and evolution of the disease in 177 sarcoidosis patients. A group of 104 individuals without sarcoidosis was included as control. Genotyping was done by a polymerase chain reaction (PCR) method, and SACE concentration at diagnosis was determined by a kinetic method. No differences were observed in genotype or allele distributions between patients and controls, nor between patients considering the type of presentation (Löfgren versus non-Löfgren) and evolution of the disease (acute versus chronic). As reported for healthy populations, SACE concentrations followed the pattern DD>ID>II in sarcoidosis patients, but significant differences between genotypes existed only in the Löfgren group (p = 0.003) and in acute patients (p = 0.02). SACE concentrations at diagnosis were lower in acute patients (p = 0.05) and in Löfgren's syndrome (p = 0.04), but this seemed to occur only in ID individuals (p = 0.02 and p = 0.01, respectively). No relation was thus found between I/D polymorphism and susceptibility to sarcoidosis, but ACE I/D genotyping may improve the assessment of disease activity, both at diagnosis and during the follow-up of treated and untreated patients.

    Discriminating between active and inactive sarcoidosis may be problematic in everyday clinical practice. There are numerous biochemical markers used in the diagnosis and monitoring of sarcoidosis. Somatostatin receptor (SR) scintigraphy with the use of 99mTc-octreotide may be used to estimate disease activity. The aim of the paper was to assess the value of traditional biomarkers (serum angiotensin-converting enzyme [SACE], C-reactive protein, markers of calcium metabolism, bronchoalveolar lavage fluid [BALF] lymphocytes) and a novel biomarker, 8-isoprostane (8-IP) in exhaled breath condensate (EBC), in the assessment of sarcoidosis activity in relation to somatostatin receptor scintigraphy. The study included 32 patients with sarcoidosis. Scintigraphy was performed using somatostatin analogue, 99mTc-HYNIC-TOC; planar and SPECT/CT images were recorded. The study group was divided into a subgroup with positive radiotracer uptake (n = 20) and without a visible uptake (n = 12). 8-IP levels were measured in EBC by an immunoenzymatic assay. RESULTS We observed a significantly higher EBC 8-IP levels in the subgroup with positive uptake compared with those with negative uptake (19.1 ± 19.8 vs. 5.4 ± 3.5 pg/ml, P = 0.02). The levels of SACE and the percentage of BALF lymphocytes were also nonsignificantly elevated. In the group of patients with positive scintigraphy results, a positive correlation was observed between the uptake ratio and SACE (r = 0.44, P = 0.041). The results indicate low value of biochemical markers in the assessment of disease activity. SR scintigraphy may have practical usefulness in the monitoring of sarcoidosis.

    To determine inter-rater reliability of sarcoidosis-related computed tomography (CT) findings that can be used for scoring of thoracic sarcoidosis. CT images of 51 patients with sarcoidosis were scored by five chest radiologists for various abnormal CT findings (22 in total) encountered in thoracic sarcoidosis. Using intra-class correlation coefficient (ICC) analysis, inter-rater reliability was analysed and reported according to the Guidelines for Reporting Reliability and Agreement Studies (GRRAS) criteria. A pre-specified sub-analysis was performed to investigate the effect of training. Scoring was trained in a distinct set of 15 scans in which all abnormal CT findings were represented. Median age of the 51 patients (36 men, 70 %) was 43 years (range 26 - 64 years). All radiographic stages were present in this group. ICC ranged from 0.91 for honeycombing to 0.11 for nodular margin (sharp versus ill-defined). The ICC was above 0.60 in 13 of the 22 abnormal findings. Sub-analysis for the best-trained observers demonstrated an ICC improvement for all abnormal findings and values above 0.60 for 16 of the 22 abnormalities. In our cohort, reliability between raters was acceptable for 16 thoracic sarcoidosis-related abnormal CT findings. (orig.)

ICC ranged from 0.91 for honeycombing to 0.11 for nodular margin (sharp versus ill-defined). The ICC was above 0.60 in 13 of the 22 abnormal findings. Sub-analysis for the best-trained observers demonstrated an ICC improvement for all abnormal findings and values above 0.60 for 16 of the 22 abnormalities. In our cohort, reliability between raters was acceptable for 16 thoracic sarcoidosis-related abnormal CT findings. (orig.)

    BAL lymphocyte percentages, quantitated gallium-67 lung uptake, and SACE levels have all been proposed as measures of disease activity in sarcoidosis. We analyzed 32 paired sera and BAL fluids from sarcoidosis patients by high-resolution agarose electrophoresis to look for protein changes characteristic of systemic or local inflammation and compared the results with those from the above tests. Nine patients (group 1) had serum inflammatory protein changes and increased total protein, albumin, beta 1-globulin (transferrin), and gamma-globulin levels in fluid recovered by BAL. Thirteen patients (group 2) had normal protein levels in sera but abnormal protein levels in BAL specimens. Ten patients (group 3) had normal protein levels in sera and in BAL specimens. Patients in groups 1 and 2 had a disproportionate increase in beta 1-globulin (transferrin) and gamma-globulin levels in their BAL specimens. The BAL lymphocyte percentage changes paralleled the BAL protein level changes, suggesting relationships among the immunoregulatory role of these cells, increased local immunoglobulin synthesis, and the pathogenesis of altered alveolar permeability. Gallium-67 uptake was highest in patients with serum inflammatory protein changes. Thus, systemic inflammation may facilitate pulmonary gallium-67 uptake, possibly by changes in BAL fluid or serum transferrin saturation and/or kinetics. SACE levels showed no relationship to changes in the levels of serum or BAL proteins. These data suggest that the various proposed measures of disease activity reflect different aspects of inflammation in sarcoidosis

    Full Text Available Sarcoidosis involves abnormal collections of inflammatory cells (granulomas which may form as nodules in multiple organs. 90% of affected patients have respiratory tract abnormalities. We present a 61-year-old male with sarcoidosis who was admitted for respiratory distress. Fibrosing mediastinitis was seen in the chest computograph. Management was conservative and included steroids, antibiotics, and oxygen therapy. Sarcoidosis and fibrosing mediastinitis are rare. Fibrosing mediastinitis is more commonly seen with histoplasmosis. We explore the clinical similarities between histoplasmosis and sarcoidosis. We also explore the potential cause and effect relationship and workup for each disease entity.

    Full Text Available La afectación cardíaca en pacientes con sarcoidosis está siendo cada vez más reconocida y se asocia con mal pronóstico. Aunque en su patogénesis están implicados los factores ambientales y genéticos, la etiología de la sarcoidosis cardíaca no es clara. Las manifestaciones clínicas incluyen alteraciones de la conducción aurículo-ventricular, arritmias e insuficiencia cardíaca congestiva. Es una entidad extremadamente difícil de diagnosticar debido a que las manifestaciones clínicas son inespecíficas, y la sensibilidad y la especificidad de las modalidades de diagnóstico son limitadas. El tratamiento cardíaco óptimo no ha sido bien definido, y aunque los corticoides siguen siendo el pilar del manejo, hay poca evidencia de la dosis o la duración de la terapia. Se expone el caso de una paciente con sarcoidosis cardíaca aislada, que debutó con extrasístoles ventriculares y progresó a falla cardiaca y arritmias ventriculares sostenidas.

    Core-needle biopsy guided by ultrasound can be performed for investigating peripheral lymph node (PLN). The aim of this study was to determine the efficacy of this technique in sarcoidosis. Retrospective review of files of all patients in the database of the radiology department of Avicenne university hospital who underwent PLN biopsies guided by ultrasound from January 2008 to June 2011 (n=292). Cases with either granulomas at histology with the procedure or with a final diagnosis of sarcoidosis were included in the study. The histological specimens were adequate in 282 out of 292 cases (96%) showing non-caseating granulomas in 22 cases (n=20 patients with a final diagnosis of sarcoidosis and n=2 patients with tuberculosis). After reviewing clinical files of the 282 patient, 22 were confirmed to have sarcoidosis, at initial presentation (n=19) or later during flare-up or relapse (n=3) with only 2 patients having no granuloma on PLN biopsy. PLN were palpable in 18 cases and only detected by (18F)FDG-PET/CT showing increased PLN uptake in 4 cases. The sensitivity and specificity of adequate biopsy were 91 and 99% and the positive and negative predictive values were 91 and 99%, respectively. Core-needle biopsy guided by ultrasound has a high efficacy for evidencing granulomas in sarcoidosis patients with PLN involvement either clinically palpable or in the presence of (18F)FDG-PET/CT uptake.

    1983-01-01

    Studies of the course of sarcoidosis have emphasized that patients with hilar or mediastinal adenopathy usually recover within several years or develop dissemination to the lungs. Chronic hilar and mediastinal adenopathy persisting with little or no change for many decades is an important subgroup that has not received adequate attention. Twelve such patients have been studied. Seven remained asymptomatic, despite persistent adenopathy, for a mean period of 16 years; two with disfiguring facial sarcoids received corticosteroids for 18 and 27 years, respectively, and three patients after ten years of stable adenopathy developed pulmonary infiltrates. Tests performed on patients with hilar adenopathy to evaluate cellular activity after a mean interval of over 16 years included Kveim reaction (positive in nine of ten), serum angiotensin converting enzyme (elevated in eight of 12), and gallium-67 scanning (hilar uptake in all eight tested). Results were similar for patients who remained well and for those who had symptomatic or progressive disease, indicating that these parameters of granulomatous activity do not reflect the duration of the disease, its outcome, or the need for treatment

    2017-01-01

    Full Text Available Sarcoidosis is a multi-systemic disorder of unknown etiology, although commonly believed to be immune-mediated. Histologically, it is characterized by noncaseating granuloma which contrasts against the caseating granuloma seen in tuberculosis (TB, an infectious disease that closely mimics sarcoidosis, both clinically as well as radiologically. In TB-endemic regions, the overlapping clinico-radiological manifestations create significant diagnostic dilemma, especially since the management options are markedly different in the two entities. Part 1 of this review aims to summarize the clinical, laboratory, and imaging features of sarcoidosis, encompassing both typical and atypical manifestations, in an attempt to distinguish between the two disease entities.

    In a thirty-one-year-old female patient from the French West Indies with osseous sarcoidosis we were able to compare the value of three diagnostic procedures used to evaluate the skeleton: roentgenography. Tc99 m scintigraphy and Ga67 scintigraphy. The lesions of sarcoidosis involved mainly the bones of the hands and feet, but also one ankle, one wrist, both knees and the skull vault. Tc99 m proved the most sensitive procedure. Ga67 evidenced the active foci in the bones and neighboring soft tissues. Roentgenograms of the bones were the least informative. Anomalies in the metabolism of calcium were lacking, as shown by the normal PAK test, a fact that demonstrates that specific bone lesions do not play a significant part in the genesis of the increased urinary calcium excretion and hyper-calcemia found in sarcoidosis [fr

    2010-12-01

    Full Text Available Common causes of hiccups are over-distension of the stomach, a sudden change in gastrointestinal temperature, excessive alcohol and tobacco ingestion, and sudden excitement or emotional changes. Common presenting symptoms of sarcoidosis include cough, dyspnea, and chest pain. It is very rare for a sarcoidosis patient to present with hiccups. A 48-year-old man presented with hiccups of 2 weeks' duration. He denied having headaches, earache, cough, abdominal pain, fever, or body weight loss history. On physical examination, he had no peripheral lymphadenopathies in the neck, axilla and inguinal regions, no organomegaly in the abdomen and no skin abnormalities. A neurological examination showed normal findings. Laboratory investigations revealed a normal complete blood count, liver function, renal function, serum calcium, and tumor markers. Transabdominal ultrasound was negative, and panendoscopy revealed a small healing duodenal ulcer. Chest radiography showed an enlarged right lung hilum, while computed tomography showed enlargement of multiple mediastinal lymph nodes. Endoscopic ultrasound-guided fine-needle aspiration with a 22-gauge needle and trucut biopsy with a 19-gauge needle (quick-core biopsy needle were performed, and cytology, cell block and histology revealed non-caseating granuloma, with negative tuberculous and fungus cultures. Mediastinal lymph node due to sarcoidosis can be a rare cause of hiccups.

    We present a patient with Cushing disease apparently suppressing sarcoidosis, which was unmasked following surgical resection of a pituitary adrenocorticotropin (ACTH)-producing microadenoma. Case report and a short review of the literature published in this area. A 46-year-old Caucasian woman presented with symptoms of hypercortisolism such as progressive weight gain, Cushingoid appearance, proximal myopathy, easy bruising, and amenorrhea. Blood testing including inferior petrosal sinus sampling uncovered an ACTH-producing microadenoma in the right aspect of the anterior pituitary gland for which the patient underwent transphenoidal resection. Maintenance corticosteroid therapy was implemented, and the signs and symptoms of Cushing disease began to resolve. Three months after surgery, multiple erythematous painful nodules developed on the patient's arms. Erythema nodosum (EN) was diagnosed clinically and a suspicion of underlying sarcoidosis was substantiated by lung imaging and elevated plasma interleukin (IL)-2 receptor. One month later, the lesions spontaneously resolved without therapy other than maintenance glucocorticoid replacement. Physicians should be aware that patients undergoing successful treatment of Cushing syndrome may have a flare-up or emergence of a corticosteroid-responsive disease.

    Sarcoidosis and amyloidosis are both multisystem disorders, which may involve the heart; however, isolated cardiac disease is rare. Diagnosis of cardiac sarcoidosis and amyloidosis is crucial because the patient prognosis is dependent on cardiac involvement and early treatment. Echocardiography is the first line imaging modality in the diagnostic work-up of both diseases, possibly giving hints towards the correct diagnosis. Besides myocardial biopsy and radionuclide studies cardiac magnetic resonance imaging (MRI) is routinely performed in patients suspect of having infiltrative cardiomyopathy. The T1 mapping procedure is currently being evaluated as a new technique for detection and quantification of global myocardial enhancement, as seen in cardiac amyloidosis. Sensitivities and specificities for detection of cardiac sarcoidosis and amyloidosis can be significantly improved by MRI, especially with late gadolinium enhancement (LGE) imaging. In cardiac sarcoidosis the use of LGE is outcome-related while in amyloidosis analysis of T1-mapping may be of prognostic value. If cardiac involvement in sarcoidosis or amyloidosis is suspected cardiac MRI including LGE should be performed for establishing the diagnosis. (orig.) [German] Die Sarkoidose und Amyloidose sind Multisystemerkrankungen, in deren Verlauf es zu einer kardialen Beteiligung kommen kann.

    A case of sarcoidosis limited to the central nervous system is described in which the diagnosis was suggested by high Ga-67 uptake in the cranial and spinal meninges. The diagnosis was confirmed by meningeal biopsy. Treatment with oral corticosteroids resulted in clinical improvement and marked reduction in Ga-67 uptake in the meninges. This is the first reported case of the central nervous system sarcoid diagnosed by Ga-67 imaging

    1984-03-01

    Serum angiotensin-converting enzyme (SACE) levels were measured in 44 subjects six weeks after acute pulmonary histoplasmosis. All patients were infected in a common-source outbreak of histoplasmosis which occurred on one day. All patients had both strictly defined clinical and serologic evidence of infection. The SACE activity was elevated at six weeks compared to normal controls, and seven of the 44 had levels more than 2 SD above the normal mean. SACE levels were also measured at three and 24 weeks after acute infection in a smaller number of the same subjects. Serial observations demonstrated that all subjects (including those with normal and elevated SACE at six weeks) had a rise and fall in SACE activity following symptomatic acute pulmonary histoplasmosis. Our findings suggest that elevated SACE does not reliably separate sarcoidosis from histoplasmosis, although elevations in histoplasmosis are much less common and may occur only briefly following acute pulmonary histoplasmosis. More important, it seems that SACE activity rises acutely in all patients with symptomatic acute histoplasmosis and then falls gradually toward baseline over several months, coinciding temporally with the granulomatous response.

  9. The diagnostic challenge of pulmonary tumour thrombotic microangiopathy as a presentation for metastatic gastric cancer: a case report and review of the literature

    2015-01-01

    Pulmonary tumour thrombotic microangiopathy (PTTM) is a rare complication of metastatic cancer with a distinct histological appearance which presents with dyspnoea and pulmonary arterial hypertension and leads to death in hours to days. It is a challenging diagnosis to make ante mortem, in part due to the rapid clinical decline. Herein, we report a case of a young woman initially felt to have pulmonary sarcoidosis but who then died eight days later from what was found at post mortem to be PTTM. A 41 year old Caucasian woman presented with progressive dyspnoea. Computed tomography of her thorax showed diffuse tiny centrilobular nodules in a tree-in-bud appearance along with small volume mediastinal lymphadenopathy. A presumptive diagnosis of pulmonary sarcoidosis was made; bronchoscopy with transbronchial lung biopsy was arranged to confirm the diagnosis. However, she rapidly deteriorated and died eight days later. Post mortem examination revealed metastatic poorly differentiated gastric adenocarcinoma with PTTM being the final cause of death. This case demonstrates the diagnostic difficulties in such a rare and rapidly fatal oncological complication; a greater awareness amongst clinicians may help make a positive diagnosis in the short window of time available. Little is known about its pathogenesis, and even less about optimal management strategies. We review the literature to demonstrate the clinical characteristics that might provide clues towards an ante mortem diagnosis, and highlight how imatinib may provide the key to treating PTTM.

    Sarcoidosis is a systemic inflammatory disease characterized by non-necrotizing granulomas in involved organs, most commonly the lung. Description of patient characteristics in the Western United States is limited. Furthermore, blood-based measures that relate to clinical sarcoidosis phenotypes are lacking. We present an analysis of a prospective, longitudinal sarcoidosis cohort at a Northern Californian academic medical center. We enrolled 126 sarcoidosis subjects and 64 healthy controls and recorded baseline demographic and clinical characteristics. We used regression models to identify factors independently associated with pulmonary physiology. We tested whether blood transcript levels at study entry could relate to longitudinal changes in pulmonary physiology. White, non-Hispanics composed ~70% of subjects. Hispanics and Blacks had a diagnostic biopsy at an age ~7 years younger than whites. Obstructive, but not restrictive, physiology characterized Scadding Stage IV patients. Subjects reporting use of immunosuppression had worse FEV1%p, FVC%p, and DLCO%p compared to subjects never treated, regardless of Scadding stage. We defined sarcoidosis disease activity by a drop in pulmonary function over 36 months and found that subjects meeting this definition had significant repression of blood gene transcripts related to T cell receptor signaling pathways, referred to as the "TCR factor." Obstructive pulmonary physiology defined Stage IV patients which were mostly white, non-Hispanics. Genes comprising the composite gene expression score, TCR factor, may represent a blood-derived measure of T-cell activity and an indirect measure of active sarcoidosis inflammation. Validation of this measure could translate into individualized treatment for sarcoidosis patients.

    Full Text Available Abstract Introduction Sarcoidosis is an inflammatory disorder characterized by the presence of non-caseating granulomas in affected organs. The presence of CD4-positive T lymphocytes and macrophages in affected organs suggests an ongoing immune response. Systemic corticosteroids remain the mainstay of treatment, but therapy is often limited by adverse effects. This is the first report of the use of adalimumab (HUMIRA®, Abbott Laboratories, North Chicago, IL, USA, an anti-tumor necrosis factor monoclonal antibody, in a patient with systemic sarcoidosis with bone marrow involvement. Case presentation A 42-year-old African-American man with a medical history significant for hypertension and diabetes mellitus presented with anemia and thrombocytopenia of two months duration. The patient underwent physical examination, bone marrow aspiration and biopsy, chest X-ray, acid-fast bacilli stain, computed tomography with contrast, and additional laboratory tests. He was diagnosed with systemic sarcoidosis with splenomegaly and bone marrow involvement. Drug therapy included prednisone, which had to be discontinued owing to adverse effects, and adalimumab. Conclusion This is the first report describing the use of adalimumab in a patient with systemic sarcoidosis with bone marrow involvement. Tumor necrosis factor antagonism with adalimumab was efficacious and well-tolerated in this patient and may be considered as a treatment option for similar cases.

    Full Text Available Crohn’s disease is a chronic, idiopathic autoimmune disorder that primarily targets the gastrointestinal (GI system. It is characterized by transmural inflammation of the GI tract that can occur anywhere from the mouth to the anus. Not infrequently, the disease may also have extraintestinal manifestations (EIMs that can affect almost any organ system. It is estimated that EIMs affect up to 36% of patients with Crohn’s disease, but the incidence and prevalence of pulmonary involvement are variable in the literature and may be as low as 0.4%. There are few case reports documenting pulmonary manifestations, as they are often overlooked, especially if respiratory symptoms are present before the diagnosis of GI manifestations, as in the present case. A 44-year-old otherwise healthy woman presented with nonspecific respiratory complaints, recurrent pneumonias, and multiple computed tomography images showing diffuse, migratory, nodular, and consolidative parenchymal lung disease, with a largely unremarkable infectious and rheumatologic evaluation. Lung biopsy revealed necrotizing and nonnecrotizing granulomas, raising concern for sarcoidosis. Subsequent imaging revealed an incidental mass in the cecum. Biopsy of the cecum lesion revealed acute cryptitis, crypt abscess, and a single poorly formed granuloma, suggesting the possibility of Crohn’s disease. In this report, we present a patient whose pulmonary manifestations ultimately led to the diagnosis of Crohn’s disease.

    Pleural effusion induced by sarcoidosis is rare, and pleural sarcoidosis is often diagnosed by thoracoscopic surgery. The diagnosis of pleural sarcoidosis using thoracentesis may be less invasive when sarcoidosis is already diagnosed histologically in more than one organ specimen. Here we report the case of a 64-year-old woman with pleural sarcoidosis diagnosed on the basis of an increased CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis. This case report is important because it highlights the usefulness of the CD4/CD8 lymphocyte ratio in pleural effusion as an indicator of pleural involvement of sarcoidosis. A 64-year-old Japanese woman visited our hospital with an initial symptom of dyspnea on exertion for a period of 4 months. Chest computed tomography showed bilateral hilar and multiple mediastinal lymphadenopathy, multiple small nodular shadows in her bilateral lungs, small nodular shadows along the interlobar pleura, and bilateral pleural effusion. Her serum angiotensin-converting enzyme and soluble interleukin-2 receptor levels were elevated. Histological analysis of a resected subcutaneous nodule, and biopsy specimens from a right mediastinal lymph node and from her right lung revealed non-caseous epithelioid granulomas. Her bronchoalveolar lavage fluid exhibited a predominance of lymphocytes together with an increase in the CD4/CD8 lymphocyte ratio. The lymphocytic predominance and the increased CD4/CD8 lymphocyte ratio were also detected in the right-sided pleural effusion fluid obtained by thoracentesis. We diagnosed sarcoidosis with pleural involvement. Because pleural effusion did not resolve spontaneously and her symptom of dyspnea on exertion worsened, corticosteroid therapy was initiated, which ameliorated the sarcoidosis and the pleuritis. Analysis of the CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis may be helpful for the diagnosis of pleural sarcoidosis when the diagnosis is already made

    We report a case of fulminant sarcoidosis in a 28-year-old man presenting with skin nodules, multifocal small and large joint arthralgias, and blurred vision. Characteristic bone, soft tissue, articular, and CNS findings were evident on multimodality imaging. Bony abnormalities included near-complete destruction of a distal phalanx, ''lace-like'' lucent lesions, erosive arthritis, lytic lesions with and without sclerotic margins, and bone marrow replacement visible only on MRI. The extent of bony disease at time of presentation was unusual. We review the widely varying reported prevalence of imaging findings of bony sarcoidosis in the literature, and discuss reasons for this variability. We found that musculoskeletal findings at US and MRI were less specific than radiographic and CT findings, but were useful in quantifying extent of disease. (orig.)

  16. A Diagnostic Dilemma: Metastatic Testicular Cancer and Systemic Sarcoidosis – A Review of the Literature

    Full Text Available Sarcoidosis is a multisystem disease that most commonly involves the lungs and the lymph nodes, but with genitourinary tract involvement, can easily mimic testicular cancer with metastasis to the lungs. We describe the case of a 30-year-old African-American male who presented with complaints of a headache, skin lesions, and a scrotal mass. A computed tomography scan of the head showed lesions in the frontotemporal and pons region, causing obstructive hydrocephalus. An ultrasound of the scrotum showed an enlarged epididymis bilaterally as well as a solid hypoechoic ill-defined mass on the right side, separate from the intact testis. Given the high suspicion for testicular malignancy with brain metastasis, a right orchiectomy was completed. The pathology revealed non-caseating necrotizing granulomas that stained negative for tubercular and fungal organisms, which was consistent with sarcoidosis. Additionally, the patient’s skin and central nervous system (CNS lesions improved on steroids that had been started for cerebral edema. Given the predilection of testicular cancer for CNS metastasis, neurosarcoidosis can also be mistaken for testicular cancer metastasis to the CNS, as seen in our case. Differentiating testicular cancer from genitourinary sarcoidosis is difficult but can be clarified using a combination of clinical presentation, epidemiology, serum markers (ACE, AFP, B-HCG, biopsies from skin/lymph nodes, and sometimes imaging. It is critical to differentiate genitourinary sarcoidosis from malignancy, as a misdiagnosis can lead to unnecessary surgical interventions, which have important implications for future fertility. There can also be a coexistence of as well as an association between testicular cancer and sarcoidosis, which should be recognized by health care providers. Both authors contributed equally to the manuscript.

    Directory of Open Access Journals (Sweden)

    Andrew Levy

    2018-05-01

    Full Text Available In this review, we argue for the use of high-resolution computed tomography (HRCT over chest X-ray in the initial evaluation of patients with sarcoidosis. Chest X-ray, which has long been used to classify disease severity and offer prognostication in sarcoidosis, has clear limitations compared with HRCT, including wider interobserver variability, a looser association with lung function, and poorer sensitivity to detect important lung manifestations of sarcoidosis. In addition, HRCT offers a diagnostic advantage, as it better depicts targets for biopsy, such as mediastinal/hilar lymphadenopathy and focal parenchymal disease. Newer data suggest that specific HRCT findings may be associated with important prognostic outcomes, such as increased mortality. As we elaborate in this update, we strongly recommend the use of HRCT in the initial evaluation of the patient with sarcoidosis.

  1. Diabetes insipidus secondary to sarcoidosis presenting with caseating granuloma

    2011-01-01

    Diabetes insipidus is a rare complication of sarcoid infiltration of the hypothalamic-pituitary region. Non-caseating granuloma formation is typical of sarcoidosis. Anterior and posterior pituitary function may be affected. MRI coupled with endocrinology assessment is the usual method of investigation. A 25-year-old Caucasian male with no significant medical history presented with polyuria and polydipsia. Water deprivation test confirmed diabetes insipidus. CT scanning of the chest confirmed lymphadenopathy. Lymph node biopsy revealed caseating granuloma. Extensive investigation for tuberculosis was negative. The patient was started on intranasal desmopressin and steroids with marked improvement in symptoms. This is the first reported case of neurosarcoidosis with diabetes insipidus and caseation on histology that we are aware of. Differentiating between caseation due to sarcoidosis and tuberculosis on histology is possible by the use of special stains. Return of normal endocrine function is unusual and the patient is likely to require desmopressin therapy for life. PMID:22707619

The gold standard of diagnosis of small fiber neuropathy (SFN is the quantification of small nerve fibers in skin biopsies in combination with patient history and psychophysical tests; a new technique is the quantification of small nerve fibers in the cornea using cornea confocal microscopy (CCM. Here, we studied small fiber morphology in sarcoidosis patients with neuropathic pain using skin biopsies, CCM, and quantitative sensory testing (QST. Our aim was to construct specific phenotypes of neuropathic pain in sarcoidosis. Fifty-eight patients with a confirmed diagnosis of sarcoidosis and with moderate-to-severe neuropathic pain were tested. Decreased intraepidermal nerve fiber density (IENFD from skin biopsies was found in 28% of patients, and CCM abnormalities were observed in 45% of patients. There was no correlation between CCM and IENFD abnormalities. Eighty-three percent of patients had abnormal thermal detection thresholds, a sign of small fiber dysfunction. Based on the presence or absence of abnormalities in IENFD and CCM, four distinct phenotypes were identified with a distinct homogeneous pattern of somatosensory symptoms. We argue that these distinct phenotypes have a similar mechanistic construct with specific phenotype-specific treatment options. Additionally, our data suggest the presence of patients with length- and nonlength-dependent SFN within this population of sarcoidosis patients.

  4. Recurrent hypercalcemia in a patient with acute sarcoidosis

    International Nuclear Information System (INIS)

    2007-01-01

    Sarcoidosis is a chronic granulomatous disease of unknown etiology characterized by the presence of noncaseating epithelioid granulomas that can take place in every organ or system of the human body. This disease can be acute or sub acute and self limited in presentation or can have a chronic course characterized by exacerbations and remissions. Hypercalcemia can be detected in 10 to 20 percent of the patients with the disease. It is caused by the over expression of vitamin D-receptor and 25-hydroxyvitamin D 1-? hydroxylase enzyme in monocytes and activated macrophages within the granuloma in a way that is resistant to the natural inhibition driven by high serum calcium Levels. This autonomous enzymatic activity leads to the overproduction of calcitriol which increase intestinal absorption of the calcium present in the diet and also increase the activity of osteoclast with consequent high bone turnover and hypercalcemia. In this report we present the case of a 49 years old man, black race, bilateral parotid gland enlargement, bilateral hilar lymphadenopathy, severe recurrent hypercaIcemia and acute renal failure in which sarcoidosis was documented as the cause of his symptoms

  5. Abnormalities in iNKT cells are associated with impaired ability of monocytes to produce IL-10 and suppress T-cell proliferation in sarcoidosis.

    Sarcoidosis is a multisystem granulomatous disorder characterized by marked T-cell expansion of T helper 1 (Th1) cells. The cause of T-cell overactivity is unknown. We hypothesized that interleukin-10 (IL-10) production by a yet undefined cell type might be defective, resulting in loss of regulation of T-cell activity. Focusing on IL-10-producing monocytes, we first showed that monocytes isolated from the peripheral blood of corticosteroid-naïve sarcoidosis patients (n = 51) produced less IL-10 compared to controls, and were less able to suppress T-cell proliferation. In addition, monocytic IL-10 production correlated negatively with disease activity score. As invariant natural killer T (iNKT) cells are known to both interact with monocytes and be reduced in sarcoidosis patients, we then asked whether iNKT-specific defects might be responsible for this reduced IL-10 production. We found that greater numbers of circulating iNKT cells was associated with higher IL-10 production. Moreover, iNKT cells enhanced monocytic IL-10 production in vitro. Defective IL-10 production and T-cell suppression by sarcoidosis monocytes could be restored following their coculture with iNKT cells, in a CD1d- and cell contact-dependent process. We suggest that reduced iNKT-cell numbers in sarcoidosis may lead to impaired monocytic IL-10 production and unchecked T-cell expansion in sarcoidosis. These findings provide fresh insight into the mechanism of sarcoidosis disease, and interaction between iNKT cells and monocytes. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    We presented a case of osseous sarcoidosis which demonstrated abnormal uptake on bone scintigram and /sup 67/Ga scintigram and comparative studies between routine radiographs of bone and RI imagings were done. The results showed that bone scintigram is more sensitive than routine radiographs and it was stressed that bone scintigram should precede radiographic skeletal survey. The significance of abnormal uptake on /sup 67/Ga scintigram seems to need further investigation.

    Sarcoidosis is a systemic granulomatous disease that primarily affects the lung; it is associated with significant disparities, more commonly impacting those in the prime of their lives (age 20-50 yr, with a second peak after age 60 yr), black individuals, and women. However, the burden of disease, the ability to diagnose and prognose organ involvement and course, as well as specific treatment options, management options, and disease pathogenesis remain poorly understood. As a result, the National Heart, Lung, and Blood Institute undertook a sarcoidosis workshop, "Leveraging Current Scientific Advancements to Understand Sarcoidosis Variability and Improve Outcomes," to help address these issues by defining the scientific and clinical priorities to improve sarcoidosis care. The overarching recommendations from this workshop are outlined in the following summary and detailed in the accompanying articles. The recommendations included establishing collaborations and networks to conduct research based on consensus definitions of disease phenotypes and standards of care, and to provide clinical outreach to areas with a burden of disease to improve care. These collaborative networks would also serve as the hub to conduct clinical trials of devastating phenotypes (e.g., cardiac, neurologic, and fibrotic disease) not only for treatment but to enhance our understanding of the burden of disease. In addition, the networks would be used to leverage state-of-the-art "omics" and systems biology research, as well as other studies to advance understanding of disease pathogenesis, and development of biomarkers and therapeutic targets, with a goal to translate this information to improve care of individuals with sarcoidosis.

    Molecular studies on tuberculosis (TB) are rare in low-resource countries like Benin, where data on molecular study on previously treated TB cases is unavailable. From January to December 2014, all smear- and culture-positive previously treated pulmonary TB patients from all TB clinics were systematically recruited. Drug susceptibility testing and spoligotyping were performed on all isolates. Of the 100 patients recruited, 71 (71.0%) were relapse cases and 24 (24.0%) were failure cases, while 5 (5.0%) were default cases. Resistance rate to any first-line drug was 40.0%, while 12.0% of strains were multidrug-resistant (MDR) and no strain was extensively drug-resistant (XDR). A total of 40 distinct spoligotypes were found to be corresponding to a genotypic diversity of 40.0%. ST61 was the most predominant spoligotype with prevalence of 33.0%. In all, 31 single spoligotypes and nine clusters were observed with 2 to 33 strains per cluster giving a clustering rate of 69.0%. Euro-American (Lineage 4) was the most prevalent lineage (74.0%) and Lineage 2 was associated with resistance to streptomycin. This first insight into genetic diversity of previously treated pulmonary TB patients in Benin showed a relatively high genetic diversity of Mycobacterium tuberculosis .

    Full Text Available Arthritis and tenosynovitis are frequently reported as complications of inflammatory bowel diseases. About 10% of patients with ulcerative colitis presents articular inflammation, usually in the phases of activity of intestinal disease. Tenosynovitis is also a frequent complication of ulcerative colitis. We describe here a case of tenosynovitis of both ankles occurring in a patient affected by ulcerative colitis not in active phase. Chest X-ray and TC showed hilar lymphonode enlargement and transbronchial biopsy confirmed the diagnosis of sarcoidosis. In this disease tenosynovitis is very rare, unlike arthritis that is rather common. In conclusion we observed a case of ankle bilateral tenosynovitis as onset manifestation of sarcoidosis.

Cutaneous involvement occurs in 25% of cases with a wide range of clinical presentation. The onset of scars is unsual although clinically characteristic of cutaneous sarcoidosis. Most patients with scar sarcoidosis have a systemic disease. It is reported the case of a 65 year-old woman that developed scar nodules 20 years after she had had surgical procedures without systemic manifestations. It is worth mentioning the importance of investigating sarcoidosis with inflammatory alterations in praevia scars.

    Asthma is thought to be a Th2 disease while sarcoidosis is considered a Th1 granulomatous disorder. Organising pneumonia is a histologic pattern of lung injury. When it has no recognisable cause it is defined as cryptogenic organising pneumonia. We herein report the case of a patient with recurrent and steroid sensitive organising pneumonia associated with chronic sarcoidosis in an atopic, moderate persistent asthmatic patient. Each disease has been documented with transbronchial biopsies and recurrence of organising pneumonia was suggested by clinical features and by follow up HRCT which shows distinctive signs even in associated disease. Steroids are the mainstay of therapy for these disorders and especially for the consolidated processes typical of organising pneumonia but prognostic indices for relapse and progression are lacking.

    The purpose of this study was to assess the utility of (18)F-FDG PET/CT for detection of inflammation in granulomatous sites and management of patients with chronic sarcoidosis. The 3 specific aims were to assess differences between (18)F-FDG PET/CT and multidetector CT (MDCT) findings, to compare (18)F-FDG PET/CT results with serum levels of angiotensin-converting enzyme (ACE), and to determine whether (18)F-FDG PET/CT findings are associated with the decision to change therapy. We studied 90 sarcoidosis patients (mean age ± SD, 47 ± 12 y; 32 men and 58 women) with persistent symptoms who were referred for (18)F-FDG PET/CT evaluation to assess the extent of inflammation. They also underwent MDCT and measurement of serum ACE level. After the follow-up (12 ± 5 mo after (18)F-FDG PET/CT), the clinical status and changes in therapy were analyzed. (18)F-FDG PET/CT detected inflammation in 74 patients (82%) (maximum standardized uptake value, 8.1 ± 3.9). MDCT was positive for sarcoidosis in 6 additional patients (80, 89%). The difference between the 2 methods was not significant (P = 0.238, McNemar test), and their agreement was fair (κ = 0.198). Although ACE levels were significantly higher in patients with positive than negative (18)F-FDG PET/CT results (P = 0.002, Mann-Whitney test), 38 patients (51%) with positive (18)F-FDG PET/CT results had normal ACE levels. The therapy was initiated or changed in 73 out of 90 patients (81%). Both univariate and multivariate logistic regression analyses indicated that positive (18)F-FDG PET/CT results were significantly (P changes in therapy, with no contribution from age, sex, ACE level, CT results, or previous therapy. Our results indicate that (18)F-FDG PET/CT is a useful adjunct to other diagnostic methods for detecting active inflammatory sites in chronic sarcoidosis patients with persistent symptoms, especially those with normal ACE levels. (18)F-FDG PET/CT proved advantageous for determining the spread of active

    Full Text Available Most of the studies have shown a higher risk for subclinical and clinical hypothyroidism, antithyroid autoantibodies [overall antithyroid peroxidase antibodies (TPOAb], and in general, thyroid autoimmunity, overall in the female gender in patients with sarcoidosis (S. A significantly higher prevalence of clinical hypothyroidism and Graves’ disease was also described in female S patients with respect to controls. Gallium-67 (Ga-67 scyntigraphy in S patients, in the case of thyroid uptake, suggests the presence of aggressive autoimmune thyroiditis and hypothyroidism. For this reason, ultrasonography and thyroid function should be done in the case of Ga-67 thyroid uptake. In conclusion, thyroid function, TPOAb measurement, and ultrasonography should be done to assess the clinical profile in female S patients, and the ones at high risk (female individuals, with TPOAb positivity, and hypoechoic and small thyroid should have periodically thyroid function evaluations and suitable treatments.

    Despite advances in diagnosis and management, the outcomes for both lung cancer and idiopathic pulmonary fibrosis (IPF) are still unfavourable. The pathophysiology and outcomes for patients with concomitant lung cancer and IPF remains unclear. A retrospective analysis was performed of all patients presenting with concomitant IPF and lung cancer to our centre over a 3-year period. Patients with connective tissue disease, asbestos exposure, sarcoidosis, previous thoracic radiation, radiological evidence of fibrosis but no histological confirmation of lung cancer, or the use of medications known to cause pulmonary fibrosis were excluded. We describe clinical, radiological and pathological characteristics of this group. We also report the response to standardized lung cancer therapy in this cohort. Of 637 lung cancer patients, 34 were identified with concomitant IPF (5.3 %) and all were smokers. 85 % had non-small cell lung cancer, 41 % were squamous cell cancers. The majority of tumours were located in the lower lobes, peripheral and present in an area of honeycombing. Despite the fact that approximately 2/3rds of the patients had localised or locally advanced lung cancer, the outcome of therapy for lung cancer was extremely poor regardless of tumour stage or severity of IPF. At our centre, 1/20 patients with lung cancer have concomitant IPF. The majority of these tumours are small in size, peripheral in location and squamous cell carcinoma; in an area of honey combing. The outcome for concomitant lung cancer and IPF regardless of stage or therapy is poor.

    Full Text Available Giant cell myocarditis, but not cardiac sarcoidosis, is known to cause fulminant myocarditis resulting in severe heart failure. However, giant cell myocarditis and cardiac sarcoidosis are pathologically similar, and attempts at pathological differentiation between the two remain difficult. We are presenting a case of fulminant myocarditis that has pathological features suggestive of cardiac sarcoidosis, but clinically mimicking giant cell myocarditis. This patient was treated with cyclosporine and prednisone and recovered well. This case we believe challenges our current understanding of these intertwined conditions. By obtaining a sense of severity of cardiac involvement via delayed hyperenhancement of cardiac magnetic resonance imaging, we were more inclined to treat this patient as giant cell myocarditis with cyclosporine. This resulted in excellent improvement of patient’s cardiac function as shown by delayed hyperenhancement images, early perfusion images, and SSFP videos.

    Hypothalamic-pituitary (HP) neurosarcoidosis (NS) accounts for 0.5 % cases of sarcoidosis and 1 % of HP masses. Correlative data on endocrine and neurological outcomes is lacking. Retrospective case series and literature review of presentation, treatment and outcome of HP NS. Our series includes 4 men, ages 34-59, followed for a median of 7.3 years (range 1.5-17). All had optic neuropathy, multiple pituitary hormone abnormalities (PHAs) and other organ involvement by sarcoidosis (lung, sino-nasal, brain/spine and facial nerve). Two patients had central diabetes insipidus and one impaired thirst with polydipsia. After treatment with high-dose glucocorticoids, optic neuropathy improved in one case and stabilized in the others. After treatment, HP lesions improved radiologically, but PHAs persisted in all cases. Review of four published series on HP NS in addition to ours yielded 46 patients, age 37 ± 11.8 years, 65 % male. PHAs consisted of anterior hypopituitarism (LH/FSH 88.8 %, TSH 67.4 %, GH 50.0 %, ACTH 48.8 %), hyperprolactinemia (48.8 %) and diabetes insipidus (65.2 %). PHAs were the first sign of disease in 54.3 % patients. Vision problems occurred in 28.3 % patients, but optic neuropathy was not well documented in previous series. Most patients (93.5 %) received high-dose glucocorticoids followed by taper; 50 % also received other immunomodulators, including methotrexate, mycophenolate mofetil, cyclosporine, azathioprine, infliximab and hydrochloroquine. Only 13 % patients showed improvement in PHAs. All-cause mortality was 8.7 %. HP NS is a serious disease requiring multidisciplinary treatment and lifelong follow-up. Prospective multicentric studies are needed to determine a more standardized approach to HP NS and outline predictors of disease outcome.

    We report on a 41-year-old female patient suffering from obesity, binge eating more than twice a week with loss of control, eating rapidly and feeling guilty after eating, dyspnoea and chronic pain in the whole body, especially in her arms, legs and in both ankles. Furthermore, subdued mood, loss of interest and pleasure, fatigue and impaired concentration could be recognized. In the past, weight increase had been observed when corticosteroids were given against exacerbations of sarcoidosis. In the case of our patient, the beginning of sarcoidosis and increase of weight and pain correlated with augmentation of depression and psychosocial stress. Dysfunctional behavioral features and multiple interactions between diseases could be observed. We diagnosed obesity, binge eating disorder, major depression, chronic pain disease with somatic and psychical components and sarcoidosis. The patient was treated in a multimodal therapy program including psychotherapy, pharmacotherapy and psychopharmacotherapy, nutritionist advice and therapeutic exercise. A weight loss of 7.9 kg (5.9 %), well-balanced diet, reduction of binge eating and of pain intensity, mood stabilization as well as perception and expression of emotions and coping strategies in chronic diseases were achieved. Interdisciplinary treatment of patients suffering from psychosomatic, somatic and mental diseases is crucial for a good outcome. © Georg Thieme Verlag KG Stuttgart · New York.

    Chronic fatigue following inflammatory diseases has been well documented. However, little is known about possible risk factors of chronic post-inflammatory fatigue. The aim of this study was to investigate whether chronic post-inflammatory fatigue after clinical remission of the disease sarcoidosis is associated with specific dimensions of personality, psychological symptoms and baseline levels of stress hormones. Thirty-seven non-fatigued and 33 fatigued patients in clinical remission of sarcoidosis were evaluated with the Temperament and Character Inventory-short form (TCI); the Symptom CheckList-90 (SCL), and the Checklist Individual Strength (CIS). Baseline levels of ACTH and cortisol were measured in plasma. Principal component analysis with orthogonal rotation (varimax) was conducted on all personality, psychological and stress hormone data in order to obtain a smaller set of components. Logistic regression was performed to associate these components with chronic post-inflammatory fatigue. Principal component analyses identified 5 components, of which two components were significantly associated with chronic post-inflammatory fatigue. The first component comprised the personality trait Harm Avoidance and all SCL-subscales except Sleep. The second component consisted of baseline levels ACTH and cortisol, and showed an inverse association with chronic post-inflammatory fatigue. The 3 other components, consisting of respectively SCL-Sleep, TCI-Novelty Seeking-Reward Dependence-Self Transcendence, and TCI-Persistence, were not significantly associated with chronic fatigue. Chronic post-inflammatory fatigue after clinical remission of sarcoidosis is associated with a triad of risk factors: a specific personality profile with profound neurotic characteristics in combination with high levels of psychological distress, and decreased baseline ACTH/cortisol levels.

    AIM: To describe direct pulmonary artery-to-pulmonary artery anastomoses seen at pulmonary angiography in patients with chronic thromboembolic pulmonary hypertension and discuss their possible significance. MATERIALS AND METHODS: Between 1 August 2000 and 31 July 2004 43 patients (male-to-female ratio 25:18) with a diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) underwent selective pulmonary angiography to assess the extent of disease and suitability for surgical pulmonary endarterectomy. The mean pulmonary artery pressure ranged from 27-84 mmHg (average of 51 mmHg). Selective bilateral digital subtraction pulmonary angiograms performed in all individuals were reviewed for the presence of intrapulmonary collaterals. RESULTS: In 15 of the 43 patients (male-to-female ratio =7:8) definite (n=12) or probable (n=3) pulmonary artery-to-pulmonary artery anastomoses were demonstrated. Of the remaining 28 patients in whom intrapulmonary collaterals were not seen it was felt that in 16 the angiograms were of insufficient diagnostic quality (grades 4-5) to exclude their presence. Twelve patients, eight of whom had angiograms of sufficient diagnostic quality (grades 1-3), demonstrated one or more areas of luxury perfusion but intrapulmonary collaterals were not seen. CONCLUSION: Direct pulmonary artery-to-pulmonary artery anastomoses were demonstrated in patients with chronic thromboembolic pulmonary hypertension, which to our knowledge have not been previously described. The importance of these collateral vessels is unclear but they may play a role in the maintenance of pulmonary parenchymal viability in patients with chronic pulmonary embolic disease. The rate of development of these collaterals and their prognostic significance in patients with chronic thromboembolic pulmonary hypertension are areas worthy of further study

    To investigate the Th17 cell and Treg cell levels in patients with sarcoidosis, and their relation to disease activation and glucocorticoids treatment. Twenty-three sarcoidosis patients admitted in Yinzhou People's Hospital from January 2009 to December 2013 and 25 healthy subjects (controls) were included in this study. The blood samples and bronchoalveolar lavage fluid (BALF) samples were collected in all patients before and after glucocorticoids treatment. The serum angiotensin converting enzyme (SACE) levels were detected. The percentages of Th17 cells and Treg cells in peripheral blood and BALF were determined by flow cytometry, the concentrations of cytokines in serum and supernatants of BALF were measured by enzyme-linked immunosorbent assay (ELISA). The levels of ROR-γt and Foxp3 mRNA transcripts in peripheral blood mononuclear cells (PBMC) were determined by real-time quantitative PCR. The potential correlation between the percentages of Th17 or Treg cells and SACE levels was evaluated. Compared with healthy controls, significantly higher frequencies of Th17 cells (4.34%±0.89% vs 1.60% ± 0.42%), lower frequencies of Treg cells (1.28% ± 0.37% vs 3.39% ± 0.50%) in peripheral blood were observed. Higher level of ROR-γt mRNA (21.31 ± 3.55 vs 3.63 ± 1.00) and lower level of Foxp3 mRNA (1.60 ± 0.24 vs 3.12 ± 0.76) in peripheral blood were detected in sarcoidosis patients in active stage (before glucocorticoids treatment) (all PSACE (r= 0.781). The imbalance of Th17 cells and Treg cells in peripheral blood and airway may be involved in the pathogenesis of sarcoidosis, which was associated with the activity of disease, and the treatment of glucocorticoids may achieve a therapeutic effect by correcting the immune imbalance.

    Objective: To study the uptake of the 18 F-FDG in the benign pulmonary diseases with dual head SPECT coincidence detection system. Methods: Scanning were performed with dual head SPECT coincidence detection system for patients with pulmonary diseases,the uptake and the imaging characteristic of the diseases were analysed. Results: 1) In 28 tuberculosis (TB) patients, 19 cases with a negative imaging (68%, 19/28), whereas 9 cases with a positive result (32%, 9/28). The T/N value of the TB is 1.7 +- 1.2, but the T/N of the lung cancer is 4.1 +- 2.4, significantly different from them. In the skin PPD test, 9 cases with positive scans showed a 16.2 (12 - 22) mm diameter red spot, but 7 cases of negative scans with a 8.6 (0 - 15) mm diameter, both also have a significant difference. 2) Out of the 8 patients suffered from sarcoidosis, among them 5 active stage with positive scans, whereas another 3 remission cases with negative results. 3) In 18 inflammation cases, positive imagings were showed in 6 patients with cryptococcosis, mycoplasma pneumonia, mycosis, organized pneumonia, lung abscess and bacteria pneumonia. Conclusions: In some benign pulmonary diseases, 18 F-FDG imaging can be positive also. Analysing the characteristic of the imaging could rise specificity in lung cancer and also give some new clues to treatment of these benign pulmonary diseases

    A case of sarcoidosis was reported in which gallium-67 scintigraphy showed increased uptake in generalized sarcoid lesions. Gallium-67 uptake in skin lesions was also seen, which is rare in literature. A 22-year-old male patient was admitted to our hospital. The patient had a history of general fatigue, polydipsia and polyuria. On physical examination, swelling of the bilateral parotid glands and lacrimal glands was noted. There were many subcutaneous nodules, especially in both arms. Superficial lymphademopathy was also noted in cervical and inguinal regions. He complained of bilateral amblyopia, and gonioscopy revelaed some nodules of the uvea. Coexistent diabetes insipidus was diagnosed with dehydration test. Chest roentgenogram showed bilateral hilar lymphadenopathy. Gallium-67 scintigram showed increased uptake in bilateral parotid glands and lacrimal glands. There were multiple abnormal uptakes in the neck, mediastinum and the inguinal region. Abnormal uptake was also noted in the subcutaneous nodules. Biopsy was performed from the lesions in the parotid glands, cervical lymph nodes, subcutaneous nodules and triceps muscles. Diagnosis of sarcoidosis was confirmed histopathologically. (J.P.N.).

    The cardiological examination of 22 patients to be suspected of heart sarcoidosis (histologically established sarcoidosis, heart rhythm disturbances, cardiomegaly) has revealed thallium scan defects in 20 patients at rest and during exercise. In 19 patients pathologic left heart wall motions established by levocardiography applying the half axis method were found. The number of pathologic half axis shortenings correlated with ejection fraction, but not with left ventricular enddiastolic pressure and volume index, resp. Coronary heart disease could not be found by coronarography in any case. Myocardial biopsy did not show myocarditis. Cardiomyopathies, other specific heart muscle diseases or rheumatic myocarditis could not be excluded as causes of the results mentioned above. The follow-up examinations of the patients will give more detailed information on the etiology of the pathologic cardiac findings. (author)

    To assess the sensitivity, and the relative role of Ga-67 whole body, chest spot imaging, and chest SPECT, we retrospectively studied 34 cases of sarcoidosis (24 biopsy proven, 10 clinically diagnosed) with Ga-67 (111 MBq), and compared the results of lung (25 cases), muscle (25 cases), skin (3 cases), and myocardial (2 cases) biopsies. Ga-67 chest SPECT (single photon emission CT) were done in 17 cases with Siemens MultiSPECT3. Ga-67 planar imaging visualized only 2 of 12 (16.7%) lung biopsy-positive cases, 5 of 12 (41.6%) muscle biopsy-positive cases, 2 of 3 (66.7%) skin biopsy-positive cases. However, Ga-67 imaging revealed the lesions in 1 of 9 (11.1%) of muscle biopsy-negative cases, in 2 of 3 (66.7%) of skin biopsy-negative cases, and in 1 of 2 myocardial biopsy-negative cases. Ga-67 chest SPECT visualized 14 hilar lymphadenopathy (LN), 3 supraclavicular LN, and 1 myocardial sarcoidosis. Although both SPECT, and planar spot imaging detected the lesions equally, the former showed them more clearly. Compared with various biopsies, the sensitivity of Ga-67 imaging was not so high. However, Ga-67 imaging is non-invasive, easy to perform the whole body imaging, and can detect the activity of the lesions. Ga-67 SPECT showed clear imaging of the hilar, mediastinal LN, and potentially fatal myocardial sarcoidosis. (author)

    2015-01-01

    Full Text Available Sarcoidosis is an idiopathic, systemic disease that rarely involves the genitourinary tract. Here, we present a case of a 40-year-old male presented with bilateral scrotal swelling. The scrotal ultrasound showed multiple echogenic masses bilaterally ranging between 3 mm and 15 mm involving both testicles. Enlarged retroperitoneal lymph nodes were detected on the abdominal computed tomography (CT. Surgical exploration of the testes with a frozen section analysis of the left testicular mass was carried out, and it revealed noncaseating granulomas. CT scan of the chest revealed the classic bilateral hilar and mediastinal lymphadenopathy with reticulonodular infiltrates. The final pathological diagnosis was systemic sarcoidosis with bilateral testicular involvement. Treatment with high-dose corticosteroids resulted in complete resolution of the testicular mass and a significant decrease in the size of the hilar, mediastinal, and retroperitoneal lymphadenopathy.

    Distension of the main pulmonary artery (MPA) induces pulmonary hypertension, most probably by neurogenic reflex pulmonary vasoconstriction, although constriction of the pulmonary vessels has not actually been demonstrated. In previous studies in dogs with increased pulmonary vascular resistance produced by airway hypoxia, exogenous arachidonic acid has led to the production of pulmonary vasodilator prostaglandins. Hence, in the present study, we investigated the effect of arachidonic acid in seven intact anesthetized dogs after pulmonary vascular resistance was increased by MPA distention. After steady-state pulmonary hypertension was established, arachidonic acid (1.0 mg/min) was infused into the right ventricle for 16 min; 15-20 min later a 16-mg bolus of arachidonic acid was injected. MPA distension was maintained throughout the study. Although the infusion of arachidonic acid significantly lowered the elevated pulmonary vascular resistance induced by MPA distension, the pulmonary vascular resistance returned to control levels only after the bolus injection of arachidonic acid. Notably, the bolus injection caused a biphasic response which first increased the pulmonary vascular resistance transiently before lowering it to control levels. In dogs with resting levels of pulmonary vascular resistance, administration of arachidonic acid in the same manner did not alter the pulmonary vascular resistance. It is concluded that MPA distension does indeed cause reflex pulmonary vasoconstriction which can be reversed by vasodilator metabolites of arachidonic acid. Even though this reflex may help maintain high pulmonary vascular resistance in the fetus, its function in the adult is obscure.

    Tumour necrosis factor (TNF)-α, an important proinflammatory cytokine, has been implicated in the pathogenesis of sarcoidosis, a multi-systemic granulomatous disorder of unknown aetiology. Here, we report for the first time the association of TNF haplotypes and genotypes with sarcoidosis and its prognosis in the Indian population. Five potentially functional promoter polymorphisms in the TNFA gene and a LTA_NcoI polymorphism (+252 position) of the LTA gene were genotyped in a clinically well-defined cohort of North-Indian patients with sarcoidosis (n = 96) and their regional controls (n = 155). Serum TNF-α (sTNF-α) and serum angiotensin converting enzyme (SACE) levels were measured and correlated with genotypes and haplotypes. The TNFA_-1031 and TNFA_-863 polymorphisms were identified as markers for disease onset (FET P = 0·006 and 0·042 for TNFA_-1031 and TNFA_-863, respectively). Additionally, the allele A of LTA_NcoI polymorphism was shown to be prevalent in the ‘no treatment’ group (FET P = 0·005), while the G allele was associated with frequent relapses on drug withdrawal (P = 0·057). Furthermore, the TNFA-308G>A and the TNFA-238G>A polymorphisms were found to influence sTNF-α (P = 0·054 and 0·0005, respectively) and SACE levels (P = 0·0017 and 0·056, respectively). The haplotype frequencies were significantly different in the patients and the controls (P = 0·0067). The haplotype GTCCGG was identified as the major risk/susceptibility haplotype (P = 0·003) and was associated with increased SACE levels in the patient population. In conclusion, our study suggests an association of TNF polymorphisms with sarcoidosis. PMID:18062795

    Sarcoidosis is a multi-system disease characterized by the presence of non-caseating epithelioid granulomas in affected tissues, including skeletal muscle. These organized collections of immune cells have important pathophysiologic action including cytokine production leading to inflammation as well as enzymatic conversion of cholecalciferol to calcitriol via 1-α hydroxylase. There are limited reports of isolated granulomatous myositis causing hypercalcemia in pediatric patients. Our patient uniquely presented with symptoms from hypercalcemia and renal insufficiency caused by an overwhelming burden of granulomatous myositis in her lower extremities, but was otherwise asymptomatic. A 16 year old Caucasian female presented with protracted symptoms of fatigue, nausea and prominent weight loss with laboratory evidence of hypercalcemia and renal insufficiency. She lacked clinical and physical findings of arthritis, weakness, rash, uveitis, fever, lymphadenopathy or respiratory symptoms. After extensive negative investigations, re-examination yielded subtle soft tissue changes in her lower extremities, with striking MRI findings of extensive myositis without correlative weakness or serum enzyme elevation. Biopsy showed the presence of non-caseating epithelioid granulomas and calcium oxalate crystals. The patient responded well to prednisone and methotrexate but relapsed with weaning of steroids. She reachieved remission with addition of adalimumab. Sarcoidosis should be considered in patients presenting with symptomatic hypercalcemia with no apparent causes and negative routine workup. The absences of decreased muscle strength or elevated muscle enzymes do not preclude the diagnosis of granulomatous myositis.

    Full Text Available 404 sarcoidosis and 404 tuberculosis patients were examined in order to detect correlations between clinical manifestations, psychological adaptation and accentuation of personality traits and granulomatous lesions of respiratory organs in case of sarcoidosis and tuberculosis. All patients had subjective and objective examinations and answered the following questionnaires: Schmieschek questionnaire to identify accentuation of personality traits, clinical questionnaire to detect and evaluate neurotic disorders, Taylor Manifest Anxiety Scale to detect the level of anxiety. It has been found out that sarcoidosis patients are characterized both by asymptomatic course of the disease as well as diverse clinical manifestations: pain syndrome, nodal fever, intoxication with expressed general fatigue, respiratory insufficiency. It is combined with stuck, pedant, cycloid, exalted, emotive accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, neurotic depression, asthenia, with average high level of anxiety. The following is typical of tuberculosis patients: syndrome of bronchial tree lesions and respiratory insufficiency; distymny, demonstrative, excitable, exalted, anxiety-hypochondriac accentuations of personality traits, with psychological maladaptation as per the scores of autonomic imbalance, obsessive-phobic disorders and hysteria; average high level of anxiety. The strong correlation has been found between the degree of symptoms expression, level of anxiety and psychological maladaptation and the type of patient's accentuation of personality traits.

    Idiopathic pulmonary hemosiderosis, a disease of unknown etiology most often occuring in children, is characterized by recurring episodes of alveolar consolidation. Exacerbations of pulmonary hemorrhage coincide with episodes of alveolar filling; repeated episodes lead to progressive interstitial fibrosis and eventually to corpulmonale. Serial nuclear scans of the lungs after injection of radiolabeled red blood cells should parallel the pathologic and radiographic findings. We observed the accumulation of radiolabeled red blood cells in the lungs on scan images, a finding not previously reported

    Congenital heart defects that have a component of right ventricular outflow tract obstruction, such as tetralogy of Fallot, are frequently palliated in childhood by disruption of the pulmonary valve. Although this can provide an initial improvement in quality of life, these patients are often left with severe pulmonary valve insufficiency. Over time, this insufficiency can lead to enlargement of the right ventricle and to the deterioration of right ventricular systolic and diastolic function. Pulmonary valve replacement in these patients decreases right ventricular volume overload and improves right ventricular performance. To date, few studies have examined the effects of pulmonary valve replacement on left ventricular function in patients with biventricular dysfunction. We sought to perform such an evaluation. Records of adult patients who had undergone pulmonary valve replacement from January 2003 through November 2006 were analyzed retrospectively. We reviewed preoperative and postoperative echocardiograms and calculated left ventricular function in 38 patients. In the entire cohort, the mean left ventricular ejection fraction increased by a mean of 0.07 after pulmonary valve replacement, which was a statistically significant change (P < 0.01). In patients with preoperative ejection fractions of less than 0.50, mean ejection fractions increased by 0.10. We conclude that pulmonary valve replacement in patients with biventricular dysfunction arising from severe pulmonary insufficiency and right ventricular enlargement can improve left ventricular function. Prospective studies are needed to verify this finding. PMID:21720459

    Full Text Available A 34-year-old female patient, who had proximal muscle weakness for 8 months, presented with erythema nodosum lesions on the pretibial region in addition to pain, swelling, and movement restriction in both ankles for the last one month. Thoracic CT demonstrated hilar and mediastinal lymphadenopathy. She underwent mediastinoscopic lymph node biopsy; biopsy result was consistent with noncaseating granuloma. Serum angiotensin converting enzyme level and muscle enzymes have been elevated. Muscular MRI and EMG findings were consistent with myositis. Muscle biopsy was done, and myopathy was found. The patient was diagnosed with sarcoidosis, Löfgren's syndrome, and sarcoid myopathy. The patient displayed remarkable clinical and radiological regression after 6-month corticosteroid and MTX therapy.

    We presented a rare case of a 64-year-old man with a combined anomaly of the bronchus and pulmonary artery that was detected incidentally. Computed tomography showed a hyperlucent, aerated sequestered segment of the right lower lung with an independent ectopic bronchus, which had no connection to the other airway. The affected segment was supplied by its own aberrant pulmonary artery branch from the right pulmonary trunk. This anomaly cannot be classified with any of the previously reported anomalies.

    Granulomas as signs of specific inflammation of the lungs are found in various diseases with pulmonary manifestations and represent an important imaging finding. The standard imaging modality for the work-up of granulomatous diseases of the lungs is most often thin-slice computed tomography (CT). There are a few instances, e. g. tuberculosis, sarcoidosis and silicosis, where a chest radiograph still plays an important role. Further radiological modalities are usually not needed in the routine work-up of granulomatous diseases of the chest. In special cases magnetic resonance imaging (MRI) and positron emission tomography (PET)-CT scans play an important role, e. g. detecting cardiac sarcoidosis by cardiac MRI or choline C-11 PET-CT in diagnosing lung carcinoma in scar tissue after tuberculosis. The accuracy of thin-slice CT is very high for granulomatous diseases. In cases of chronic disease and fibrotic interstitial lung disease it is important to perform thin-slice CT in order to diagnose a specific disease pattern. Thin-slice CT is also highly sensitive in detecting disease complications and comorbidities, such as malignancies. Given these indications thin-slice CT is generally accepted in the routine daily practice. A thin-slice CT and an interdisciplinary discussion are recommended in many cases with a suspected diagnosis of pulmonary granulomatous disease due to clinical or radiographic findings. (orig.)

    1996-01-01

    This study was undertaken to assess whether 123 I-MIBG scintigraphy is useful to detect cardiac involvements of sarcoidosis. In 45 patients with sarcoidosis, dual SPECT with 123 I-MIBG and 201 Tl-Cl(Tl) were performed, and the findings were compared with electrocardiogram (ECG), 24 hour Holter ECG and ultrasound echocardiography. In order to evaluate cardiac involvements, Tl and MIBG extent score (E.S.) and severity score (S.S.) were calculated by a Bull's eye map in addition to visual evaluation. Abnormal findings were recognized in 8.9% of all subjects in echocardiography, in 22.2% of those in ECG and Holter ECG, in 40% of those in Tl scintigraphy, and in 64.4% of those in MIBG scintigraphy. All of the Tl and MIBG abnormalities were detected in left ventricles, especially at the basal septal wall. At the inferior wall, abnormalities were observed more frequently by MIBG than by Tl. Tl E.S., Tl S.S. and MIBG E.S. were significantly higher in 10 patients with abnormal ECG findings than in 35 patients with normal ECG findings. Also, all of 10 patients with abnormal ECG findings had abnormal MIBG image, but 3 of them showed normal Tl images. 11 of 35 patients with normal ECG findings showed abnormal Tl and MIBG images (group A), 8 of 35 patients showed normal Tl images and abnormal MIBG images (group B), and 16 of 35 patients showed normal Tl and MIBG images (group C). MIBG S.S. of group A (11.3±7.8) was significantly higher than that of group B (5.3±3.1) or group C (2.6±3.2). Furthermore, in group A, MIBG S.S. was significantly higher than Tl S.S. (5.5±2.8). In a case of normal ECG with abnormal MIBG images, we seriously suspect cardiac involvements and recommend repeated Holter ECG tests as necessary in order to detect critical arrythmia. MIBG scintigraphy appeared to be a sensitive and useful method for the early detection of cardiac sarcoidosis. (J.P.N.)

    The purpose of this study was to compare combined PET/MRI with PET/CT and cardiac MRI in the evaluation of cardiac sarcoidosis and myocarditis. Ten patients (4 men and 6 women; 56.1 ± 9.6 years old) were prospectively enrolled for evaluation of suspected cardiac sarcoidosis or myocarditis. Written informed consent was obtained. Following administration of 9.9 ± 0.9 mCi F-FDG, patients underwent standard cardiac PET/CT followed by combined PET/MRI using a simultaneous 3-T scanner. Cardiac MRI sequences included ECG-triggered cine SSFP, T2-weighted, and late gadolinium-enhanced imaging. Myocardial involvement was assessed with separate analysis of combined PET/MRI, PET/CT, and cardiac MRI data using dedicated postprocessing software. Estimates of radiation dose were derived from the applied doses of F-FDG and CT protocol parameters. Imaging was acquired with a delay from F-FDG injection of 90.2 ± 27.4 minutes for PET/CT and 207.7 ± 40.3 minutes for PET/MRI. Total scan time for PET/MRI was significantly longer than for PET/CT (81.4 ± 14.8 vs 12.0 minutes, P PET/MRI compared with PET/CT (6.9 ± 0.6 vs 8.2 ± 1.1 mSv, P = 0.007). There was no significant difference in the number of positive cases identified between combined PET/MRI (n = 10 [100%]), PET/CT (n = 6 [60%]), and cardiac MRI (n = 8 [80%]), P = 0.091. Simultaneous cardiac PET/MRI is feasible in the evaluation of cardiac sarcoidosis and myocarditis achieving diagnostic image quality.

    Full Text Available Amy Hawkins, Robert TullohDepartment of Congenital Heart Disease, Bristol Royal Hospital for Children, Bristol UKAbstract: Pulmonary hypertension was once thought to be a rare condition and only managed in specialized centers. Now however, with the advent of echocardiography, it is found in many clinical scenarios, in the neonate with chronic lung disease, in the acute setting in the intensive care unit, in connective tissue disease and in cardiology pre- and postoperatively. We have a better understanding of the pathological process and have a range of medication which is starting to be able to palliate this previously fatal condition. This review describes the areas that are known in this condition and those that are less familiar. The basic physiology behind pulmonary hypertension and pulmonary vascular disease is explained. The histopathologic process and the various diagnostic tools are described and are followed by the current and future therapy at our disposal.Keywords: pulmonary hypertension, congenital heart disease, pulmonary vascular resistance, pulmonary vasodilators

  15. Treatment of Chronic Thromboembolic Pulmonary Hypertension: The Role of Medical Therapy and Balloon Pulmonary Angioplasty.

    Fernandes, Timothy M; Poch, David S; Auger, William R

    2016-01-01

    Chronic thromboembolic pulmonary hypertension (CTEPH) is a potentially curable disease when treated with pulmonary thromboendarterectomy (PTE). However, even at experienced surgical centers, nearly one-third of patients with CTEPH will be deemed inoperable for reasons including distal disease, comorbidities, or out-of-proportion pulmonary hypertension. It is in these patients with inoperable CTEPH that pulmonary hypertension (PH)-targeted medical therapy and balloon pulmonary angioplasty have potential therapeutic value. Previous unblinded cohort trials have assessed PH-targeted medical therapy in various subpopulations of CTEPH patients using epoprostenol, treprostinil, sildenafil, bosentan, and iloprost, each demonstrating measurable pulmonary hemodynamic effects. However, riociguat, a soluble guanylate cyclase stimulator, is the first FDA-approved therapy for inoperable CTEPH to demonstrate both an improvement in functional capabilities (6-minute walk time) as well as significant gains in secondary pulmonary hemodynamic end points in a large placebo-controlled trial. Balloon pulmonary angioplasty is an interventional procedure using telescoping catheters placed in the pulmonary arteries, through which wires and balloons are used to mechanically disrupt chronic clot material and relieve pulmonary vascular obstruction. Contemporary case series from multiple centers worldwide have demonstrated pulmonary hemodynamic improvement with this approach. As a result of these advances, patients with inoperable CTEPH who had few options as recently as 5 years ago now have alternatives with emerging evidence of therapeutic efficacy.

    Full Text Available A 54-year-old woman with a past history of silicone augmentation mammoplasty was admitted with fever and dyspnea with diffuse interstitial shadows on computed tomography (CT. Although radiological findings were atypical, we diagnosed sarcoidosis by laboratory, microbiological, and bronchoalveolar lavage fluid analysis. Corticosteroids ameliorated the condition, but she had recurrent of fever and CT revealed miliary nodules while interstitial shadows disappeared. Liver biopsy showed that noncaseating granuloma and Ziehl-Neelsen stain was positive. We diagnosed miliary tuberculosis which developed during corticosteroid therapy. Antituberculotic therapy resulted in favorable outcome. Possibility exists that onset of sarcoidosis was induced by mammoplasty, namely, human adjuvant disease.

    This study aimed to evaluate the diagnostic yield of fiberoptic bronchoscopic (FOB) transbronchial biopsy and its relation with quantitative findings of high resolution computerized tomography (HRCT). A total of 83 patients, 19 males and 64 females with a mean age of 45.1 years diagnosed with sarcoidosis with complete records of high resolution computerized tomography were retrospectively recruited during the time period from Feb 2005 to Jan 2015. High resolution computerized tomography scans were retrospectively assessed in random order by an experienced observer without knowledge of the bronchoscopic results or lung function tests. According to the radiological staging with HRCT, 2.4% of the patients (n=2) were stage 0, 19.3% (n=16) were stage 1, 72.3% (n=60) were stage 2 and 6.0% (n=5) were stage 3. This study showed that transbronchial lung biopsy showed positive results in 39.7% of the stage I or II sarcoidosis patients who were diagnosed by bronchoscopy. Different high resolution computerized tomography patterns and different scores of involvement did make a difference in the diagnostic accuracy of transbronchial biopsy (p=0.007).

    To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. The complications manifesting mainly as pulmonary nodules were lung cancer (4/4), tuberculosis (1/2), and Kaposi's sarcoma (1/1). Pulmonary consolidation was a main feature in bacterial infection (4/4), fungal infection (3/4), tuberculosis (1/2), chlamydial infection (1/1), and varicellar pneumonia (1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia (4/6), and increased interstitial making was a predominant radiographic feature in CMV pneumonia (2/6). The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

  2. Immersion Pulmonary Edema in Female Triathletes

    Eric A. Carter

    2011-01-01

    Full Text Available Pulmonary edema has been reported in SCUBA divers, apnea divers, and long-distance swimmers however, no instances of pulmonary edema in triathletes exist in the scientific literature. Pulmonary edema may cause seizures and loss of consciousness which in a water environment may become life threatening. This paper describes pulmonary edema in three female triathletes. Signs and symptoms including cough, fatigue, dyspnea, haemoptysis, and rales may occur within minutes of immersion. Contributing factors include hemodynamic changes due to water immersion, cold exposure, and exertion which elevate cardiac output, causing pulmonary capillary stress failure, resulting in extravasation of fluid into the airspace of the lung. Previous history is a major risk factor. Treatment involves immediate removal from immersion and in more serious cases, hospitalization, and oxygen administration. Immersion pulmonary edema is a critical environmental illness of which triathletes, race organizers, and medical staff, should be made aware.

    Ventricular septal defects generate 10% of all adult congenital cardiopathies. 4% to 8% of patients to whom the defect has not been corrected are in risk of developing endocarditis. Pulmonary valve endocarditis is a rare event (1.5% to 2% of all endocarditis cases) and its mean etiology is intravenous drug abuse. The most frequently isolated microorganism in these cases is staphylococcus aurous. We report a case of pulmonary valve endocarditis associated with ventricular septal defect and valvular and infundibular pulmonary stenosis caused by streptococcus sp. in a patient without past medical history of drug abuse, alcoholism or previous invasive procedures

    Chronic obstructive pulmonary disease (COPD) exacerbations have a negative impact on the quality of life of patients and the evolution of the disease. We have investigated the prognostic value of several health-related quality of life questionnaires to predict the appearance of a composite event (new ambulatory or emergency exacerbation, hospitalization, or death) over a 1-year follow-up. This was a multicenter, prospective, observational study. Patients completed four questionnaires after recovering from an exacerbation (COPD Assessment Test [CAT], a Clinical COPD Questionnaire [CCQ], COPD Severity Score [COPDSS], and Airways Questionnaire [AQ20]). Patients were followed-up until the appearance of the composite event or for 1 year, whichever came first. A total of 497 patients were included in the study. The majority of them were men (89.7%), with a mean age of 68.7 (SD 9.2) years, and a forced expiratory volume in 1 second of 47.1% (SD 17.5%). A total of 303 (61%) patients experienced a composite event. Patients with an event had worse mean scores of all questionnaires at baseline compared to patients without event: CAT=12.5 vs 11.3 (P=0.028); CCQ=2.2 vs 1.9 (P=0.013); COPDSS=12.3 vs 10.9 (P=0.001); AQ20=8.3 vs 7.5 (P=0.048). In the multivariate analysis, only previous history of exacerbations and CAT score ≥13.5 were significant risk factors for the composite event. A CAT score ≥13.5 increased the predictive value of previous exacerbations with an area under the receiver operating characteristic curve of 0.864 (95% CI: 0.829-0.899; P=0.001). The predictive value of previous exacerbations significantly increased only in one of the four trialled questionnaires, namely in the CAT questionnaire. However, previous history of exacerbations was the strongest predictor of the composite event.

    Purpose. To describe the CT findings of pathologically confirmed primary pulmonary lymphomas. Materials and methods. The CT examinations of 11 patients with pathologically proven primary pulmonary lymphoma (9 BALT lymphomas and 2 non-BALT lymphomas) were retrospectively reviewed by three radiologists. Evaluated findings included morphology (consolidation, mass, nodule), number and distribution of lesions. Other CT findings such as air bronchogram, lymphadenopathy atelectasis and pleural effusion were also assessed. Results. Pulmonary lesions were depicted as air-space consolidation (pneumonia-like) in 5 patients (45%), tumour-like rounded opacity in 4 (36%), and nodules in 4 (36%). Multiple and bilateral long lesions were seen in 3 patients (27%). Air bronchogram was present in 7 patients (63%), lymphadenopathy in 3 (27%), atelectasis in 4 (36%) and pleural effusion in only 1 (9%). Conclusions. Our results agree with previous studies regarding lesion patterns and their relative frequency. A smaller number of nodules and of multiple lesions were found compared with some previous studies. The most frequent pattern was airspace consolidation [it

    Full Text Available History of present illness: A 6-year-old previously healthy male presented to the emergency department with three days of left upper quadrant abdominal pain. Family endorsed one week of fevers, cough productive of yellow sputum, and non-bilious, non-bloody emesis. He denied shortness of breath and chest pain. On exam, the patient was febrile with otherwise normal vital signs. He had diffuse tenderness to his abdomen but clear lungs. Laboratory studies revealed leukocytosis to 25,000/mm3 with a left shift. Significant findings: Upright posterior-anterior plain chest films show a left lower lobe consolidation with an air-fluid level and a single septation consistent with a pulmonary abscess (white arrows. A small left pleural effusion was also present, seen as blunting of the left costophrenic angle and obscuration of the left hemidiaphragm (black arrows. Discussion: Pediatric pulmonary abscesses are rare, most commonly caused by aspiration, and the majority consequently arise in dependent portions of the lung.1 The most common pathogens in children are Streptococcus pneumoniaeand Staphylococcus aureus.1 Immunocompromised patients and those with existing pulmonary disease more commonly contract Pseudomonas aeruginosaor Bacteroides, and fungal pathogens are possible.1 Common symptoms include tachypnea, fever, and cough. Imaging is necessary to distinguish pulmonary abscesses from pneumonia, empyema, pneumatocele, and other etiologies. Plain film radiography may miss up to 18% of pulmonary abscesses yet is often the first modality to visualize an intrathoracic abnormality.2 If seen, pulmonary abscesses most often appear as consolidations with air-fluid levels. Generally, pulmonary abscesses are round with irregular, thick walls, whereas empyemas are elliptical with smooth, thin walls.3 However, these characteristics cannot definitively distinguish these processes.2 Advantages of plain films include being low cost and easily obtained.

    A 65-year-old woman visited our hospital with a complaint of acute onset dyspnea and radiological manifestations of pulmonary thromboembolism. The patient underwent an exploratory surgery to find a whitish-blue colored mass occupying almost the whole lumen of the main pulmonary arteries. Based on the pathological and radiological findings, the patient was diagnosed to have a pulmonary arterial intramural hematoma. Intramural hematomas are usually observed in the walls of the aorta, and we believe that an isolated intramural hematoma in the pulmonary artery has not been described previously.

    Pulmonary hypertension in the perinatal period can present acutely (persistent pulmonary hypertension of the newborn) or chronically. Clinical and echocardiographic diagnosis of acute pulmonary hypertension is well accepted but there are no broadly validated criteria for echocardiographic diagnosis of pulmonary hypertension later in the clinical course, although there are significant populations of infants with lung disease at risk for this diagnosis. Contributing cardiovascular comorbidities are common in infants with pulmonary hypertension and lung disease. It is not clear who should be treated without confirmation of pulmonary vascular disease by cardiac catheterization, with concurrent evaluation of any contributing cardiovascular comorbidities.

  17. NFATc3 and VIP in Idiopathic Pulmonary Fibrosis and Chronic Obstructive Pulmonary Disease.

    Anthony M Szema

    Full Text Available Idiopathic pulmonary fibrosis (IPF and chronic obstructive pulmonary disease (COPD are both debilitating lung diseases which can lead to hypoxemia and pulmonary hypertension (PH. Nuclear Factor of Activated T-cells (NFAT is a transcription factor implicated in the etiology of vascular remodeling in hypoxic PH. We have previously shown that mice lacking the ability to generate Vasoactive Intestinal Peptide (VIP develop spontaneous PH, pulmonary arterial remodeling and lung inflammation. Inhibition of NFAT attenuated PH in these mice suggesting a connection between NFAT and VIP. To test the hypotheses that: 1 VIP inhibits NFAT isoform c3 (NFATc3 activity in pulmonary vascular smooth muscle cells; 2 lung NFATc3 activation is associated with disease severity in IPF and COPD patients, and 3 VIP and NFATc3 expression correlate in lung tissue from IPF and COPD patients. NFAT activity was determined in isolated pulmonary arteries from NFAT-luciferase reporter mice. The % of nuclei with NFAT nuclear accumulation was determined in primary human pulmonary artery smooth muscle cell (PASMC cultures; in lung airway epithelia and smooth muscle and pulmonary endothelia and smooth muscle from IPF and COPD patients; and in PASMC from mouse lung sections by fluorescence microscopy. Both NFAT and VIP mRNA levels were measured in lungs from IPF and COPD patients. Empirical strategies applied to test hypotheses regarding VIP, NFATc3 expression and activity, and disease type and severity. This study shows a significant negative correlation between NFAT isoform c3 protein expression levels in PASMC, activity of NFATc3 in pulmonary endothelial cells, expression and activity of NFATc3 in bronchial epithelial cells and lung function in IPF patients, supporting the concept that NFATc3 is activated in the early stages of IPF. We further show that there is a significant positive correlation between NFATc3 mRNA expression and VIP RNA expression only in lungs from IPF patients

    Cellular components of bronchoalveolar lavage (BAL) fluid were studied in 26 sarcoid patients, 8 patients with farmer's lung, 10 healthy controls and 10 control patients. The investigations by Ga scintigraphy or transbronchial lung biopsy (TBLB) and measurement of serum angiotensin converting enzyme (SACE) activity were also carried out in 21 sarcoid patients and 8 patients with farmer's lung. 1) Percentage of foamy cells in alveolar ma crophage fraction, percentage of lymphocytes and number of mast cells were increased significantly in BLA fluid from patients with farmer's lung as compared with that from sarcoid patients. Analysis of cellular component of BAL flu id is useful for differential diagnosis of these diseases. 2) Granulomatous lung lesions were frequently observed in specimens obtained by TBLB from patients with sarcoidosis and farmer's lung who showed abnormal Ga uptake in lung. In contrast, there was no significant difference in percentage of lymphocytes in BAL fluid between patients whose pulmonary Ga uptake was positive and those in whom pulmonary Ga uptake was negative. To investigate the mechanism of pulmonary Ga accumulation in granulomatous lung disease, BAL was performed in 2 sarcoid patients and 3 patients with farmer's lung at 48 to 72 hrs after Ga injection. The radioactivity in cell fractions was evaluated at 96 hrs after Ga injection. Most of the radioactivity was found in macrophages, with little in lymphocytes. Pulmonary Ga uptake in patients with sarcoidosis and farmer' s lung reflects granuloma formation or accumulation of activated macrophages in lung, but not the intensity of T-cell alveolitis. 3) Some relationship among SACE, granulomatous lung lesions in specimens obtained by TBLB and abnormal Ga accumulation in lung or hilar lymphnodes in sarcoid patients was observed, suggesting that SACE might reflect the degree of granuloma formation in sarcoidosis.

    Full Text Available Sarcoidosis and tuberculosis are granulomatous disorders that mimic each other both clinically and radiologically. Both can present with fever and pulmonary nodules and often require the performance of transbronchial lung biopsy (TBLB for diagnosis. In recent studies, the flexible cryoprobe for carrying out TBLB has been found to be useful in the diagnosis of disorders diffusely involving the lung parenchyma. Here, we present the case of a 29-year-old man who presented with fever and cough and was found to have multiple small nodules in both lungs. TBLB with a flexible cryoprobe helped in differentiating between sarcoidosis and tuberculosis.

    Full Text Available Sarcoidosis is a risk factor for the development of cryptococcal infection due to dysfunction at T-cell level. Its rarity may, however, delay diagnosis and treatment. We describe the case of a 60-year-old man, diagnosed with sarcoidosis since 1999. He had never received systemic immunomodulatory therapy, such as corticosteroid therapy. In 2012, he was diagnosed with pulmonary cryptococcosis and treated with fluconazole. In April 2013, he presented with symptoms compatible with central nervous system (CNS infection, namely, Cryptococcus neoformans meningitis. He was treated with amphotericin B, followed by fluconazole. The clinical outcome was favourable.

    The introduction of flexible bronchoscope has revolutionized the field of pulmonary medicine and is a standard instrument used for diagnostic purpose. A retrospective analysis of the clinico-radiological profile, indication, biopsy procedure and complications, for patients undergoing bronchoscopy at one of the respiratory unit at a tertiary care center in India. Retrospective analysis of 712 bronchoscopies was done in regard to demographic profile, clinical and radiological presentation and diagnostic indication. The results were analyzed on basis of bronchoscopy inspection and histopathological specimen obtained from transbronchial (TBLB), endobronchial biopsy (EBLB) and cytology specimen by transbronchial needle aspiration (TBNA). Furthermore, diagnostic yield of each biopsy procedure and their combination was evaluated. Of 712 patients undergoing bronchoscopy, the pathological diagnosis was achieved in 384 (53.93%). Of 384 diagnosed cases, the clinic-radio-pathological diagnosis of pulmonary tuberculosis in 88 (22.19%), interstitial lung disease (ILDs) in 226 (58.85%), and lung cancer in 70 (18.22%) cases. Of 116 sputum smear negative tuberculosis patients, 88 (75.86%) were diagnosed to be pulmonary tuberculosis; the contribution of BAL being 71.59%. Of 226 ILDs, sarcoidosis was most common 148/226 (65.48%). Among 70 lung cancer diagnosed cases, squamous cell carcinoma was most common (54.28%). The results from current study reemphasizes on the diagnostic utility as well as safety of the bronchoscopy procedure. Copyright © 2015 Tuberculosis Association of India. Published by Elsevier B.V.

    To expand the search for central pulmonary arteries in six patients with absence of cardiac-pulmonary continuity, computerized axial tomography (CAT) of the chest was performed. The CAT scans were compared with previous arteriograms and pulmonary vein wedge angiograms. Three patients with type IV truncus arteriosus were studied, and none had a central, right or left pulmonary artery on CAT scan. However, two patients with tetralogy of Fallot with pulmonary atresia and a patent ductus arteriosus to the right lung demonstrated the presence of a left pulmonary artery. In addition, one child with truncus arteriosus with ''absent'' left pulmonary artery demonstrated a left pulmonary artery on the CAT scan. The CAT scan may therefore enhance our ability to search for disconnected pulmonary arteries in children with complex cyanotic congenital heart disease

    2010-02-01

    Full Text Available Abstract Background A strong genetic influence by the MHC class II region has been reported in sarcoidosis, however in many studies with different results. This may possibly be caused by actual differences between distinct ethnic groups, too small sample sizes, or because of lack of accurate clinical subgrouping. Subjects and methods In this study we HLA typed a large patient population (n = 754 recruited from one single centre. Patients were sub-grouped into those with Löfgren's syndrome (LS (n = 302 and those without (non-Löfgren's (n = 452, and the majority of them were clinically classified into those with recovery within two years (resolving and those with signs of disease for more than two years (non-resolving. PCR was used for determination of HLA-DRB1 alleles. Swedish healthy blood donors (n = 1366 served as controls. Results There was a dramatic difference in the distribution of HLA alleles in LS compared to non-LS patients (p = 4 × 10-36. Most notably, DRB1*01, DRB1*03 and DRB1*14, clearly differed in LS and non-LS patients. In relation to disease course, DRB1*07, DRB1*14 and DRB1*15 generally associated with, while DRB1*01 and DRB1*03 protected against, a non-resolving disease. Interestingly, the clinical influence of DRB1*03 (good prognosis dominated over that of DRB1*15 (bad prognosis. Conclusions We found several significant differences between LS and non-LS patients and we therefore suggest that genetic association studies in sarcoidosis should include a careful clinical characterisation and sub-grouping of patients, in order to reveal true genetic associations. This may be particularly accurate to do in the heterogeneous non-LS group of patients.

    Full Text Available Isolated Unilateral Absent Pulmonary Artery (UAPA is a rare congenital anomaly. It is usually associated with congenital heart defects. A 45 year old male patient presented with complaints of fever with cough and expectoration for 15 days and retrosternal chest discomfort for the previous 2 days. ECG showed diffuse ST segment depression with T wave inversion in the inferior and lateral leads. Coronary Angiogram done through the right femoral approach revealed diffusely diseased Left Anterior Descending (LAD artery that was totally cut off at the mid segment. The Left Circumflex (LCx artery was providing blood supply to the right middle and lower lung areas. There was another collateral arising from the Left Subclavian Artery supplying the right middle and lower lung areas. The left pulmonary artery was normal, but branches supplying the middle and lower lobes of the right lung were absent and the upper lobe branch had pulmonary stenosis. UAPA is a rare clinical entity; collaterals from coronaries are extremely rare in this condition and till now there has not been any case report of unilateral absent branch pulmonary artery with peripheral stenosis of other branches, on the affected side and associated coronary artery disease.

    1982-01-01

    In 97 patients with bronchitis, bronchial asthma, tuberculosis, sarcoidosis, pneumoconiosis, or tumors the mucociliary clearance and/or deposit pattern after inhalation of radioactively marked aerosols (1 mCi 99m Tc sulfur colloid) was studied. Normal values of the mucociliary 30 min. clearance for the central bronchial/lung periphery are 21%/15%. There was a decreased clearance with bronchitis (11/8%), bronchial asthma, emphysema, tuberculosis, sarcoidosis, trachiobronchial amyloidosis, pleural scarring or interstitial pneumona. Increased clearance (29/19%) was shown with pneumoconiosis. The correlation of deposit pattern and disease, for example, bronchitis, bronchial asthma, bullous emphysema, pleural scarring, partial lung resection, bronchopneumonia, or bronchial restriction, is described. In comparison of aerosol scintigraphy to perfusion scintigraphy and ventilation with gaseous xenon, the aerosol scintigraphy is superior to xenon for certain indications. The aerosol particles, which are larger in comparison to xenon, settle easier by obstructions or flow variations and thereby give better clinical indications of regional differences. (orig.) [de

    The authors report a case of successful detection of pulmonary embolism using gadolinium-enhanced spiral CT (Gadodiamide, 0.4 mmol/kg, 2 ml/s, delay 18 s) in a 77-year-old woman, with previous allergy to iodinated contrast medium, and renal failure, who presented with pulmonary arterial hypertension. Doppler ultrasound of the lower limbs was first performed and revealed a deep venous thrombosis of the right lower limb. To establish if venous thrombosis was the cause of pulmonary hypertension and to confirm that pulmonary endarterectomy was not indicated in this situation, several imaging modalities were performed. Lung scintigraphy and MRI were non-diagnostic. Gadolinium-enhanced spiral CT demonstrated a large thrombus located proximally and in a segmental artery of the right lower lobe. This case illustrates the potential usefulness of gadolinium as alternative contrast agent with spiral CT to diagnose pulmonary embolism and elucidate the cause of pulmonary arterial hypertension in a patient with some contraindications for iodinated contrast medium injection.

    Excessive stretching of the vascular wall in accordance with pulmonary arterial hypertension (PAH) induces a variety of pathogenic cellular events in the pulmonary arteries. We previously reported that indoxam, a selective inhibitor for secretory phospholipase A(2) (sPLA(2)), blocked the stretch-induced contraction of rabbit pulmonary arteries by inhibition of untransformed prostaglandin H(2) (PGH(2)) production. The present study was undertaken to investigate involvement of sPLA(2) and untransformed PGH(2) in the enhanced contractility of pulmonary arteries of experimental PAH in rats. Among all the known isoforms of sPLA(2), sPLA(2)-X transcript was most significantly augmented in the pulmonary arteries of rats with monocrotaline-induced pulmonary hypertension (MCT-PHR). The pulmonary arteries of MCT-PHR frequently showed two types of spontaneous contraction in response to stretch; 27% showed rhythmic contraction, which was sensitive to indoxam and SC-560 (selective COX-1 inhibitor), but less sensitive to NS-398 (selective COX-2 inhibitor); and 47% showed sustained incremental tension (tonic contraction), which was insensitive to indoxam and SC-560, but sensitive to NS-398 and was attenuated to 45% of the control. Only the rhythmically contracting pulmonary arteries of MCT-PHR produced a substantial amount of untransformed PGH(2), which was abolished by indoxam. These results suggest that sPLA(2)-mediated PGH(2) synthesis plays an important role in the rhythmic contraction of pulmonary arteries of MCT-PHR.

    Hypoxic pulmonary hypertension is characterized by the remodeling of pulmonary artery. Previously we showed that tanshinone IIA, one lipid-soluble component from the Chinese herb Danshen, ameliorated hypoxic pulmonary hypertension by inhibiting pulmonary artery remodeling. Here we explored the effects of danshensu, one water-soluble component of Danshen, on hypoxic pulmonary hypertension and its mechanism. Rats were exposed to hypobaric hypoxia for 4 weeks to develop hypoxic pulmonary hypertension along with administration of danshensu. Hemodynamics and pulmonary arterial remodeling index were measured. The effects of danshensu on the proliferation of primary pulmonary artery smooth muscle cells and transforming growth factor-β-smad3 pathway were assessed in vitro. Danshensu significantly decreased the right ventricle systolic pressure, the right ventricle hypertrophy and pulmonary vascular remodeling index in hypoxic pulmonary hypertension rats. Danshensu also reduced the increased expression of transforming growth factor-β and phosphorylation of smad3 in pulmonary arteries in hypoxic pulmonary hypertension rats. In vitro, danshensu inhibited the hypoxia- or transforming growth factor-β-induced proliferation of primary pulmonary artery smooth muscle cells. Moreover, danshensu decreased the hypoxia-induced expression and secretion of transforming growth factor in primary pulmonary adventitial fibroblasts and NR8383 cell line, inhibited the hypoxia or transforming growth factor-β-induced phosphorylation of smad3 in rat primary pulmonary artery smooth muscle cells. These results demonstrate that danshensu ameliorates hypoxic pulmonary hypertension in rats by inhibiting the hypoxia-induced proliferation of pulmonary artery smooth muscle cells, and the inhibition effects is associated with transforming growth factor-β-smad3 pathway. Therefore danshensu may be a potential treatment for hypoxic pulmonary hypertension. Copyright © 2017 Elsevier B.V. All rights

    Low O2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction (HPV) diverts pulmonary blood flow from poorly ventilated and hypoxic areas of the lung to more well-ventilated parts and is considered important for the local matching of ventilation to blood perfusion. In the present study, the effects of acute hypoxia on pulmonary and systemic blood flows and pressures were measured in four species of anesthetized reptiles with diverse lung structures and heart morphologies: varanid lizards (Varanus exanthematicus), caimans (Caiman latirostris), rattlesnakes (Crotalus durissus), and tegu lizards (Tupinambis merianae). As previously shown in turtles, hypoxia causes a reversible constriction of the pulmonary vasculature in varanids and caimans, decreasing pulmonary vascular conductance by 37 and 31%, respectively. These three species possess complex multicameral lungs, and it is likely that HPV would aid to secure ventilation-perfusion homogeneity. There was no HPV in rattlesnakes, which have structurally simple lungs where local ventilation-perfusion inhomogeneities are less likely to occur. However, tegu lizards, which also have simple unicameral lungs, did exhibit HPV, decreasing pulmonary vascular conductance by 32%, albeit at a lower threshold than varanids and caimans (6.2 kPa oxygen in inspired air vs. 8.2 and 13.9 kPa, respectively). Although these observations suggest that HPV is more pronounced in species with complex lungs and functionally divided hearts, it is also clear that other components are involved.

    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

  19. The Critical Role of Pulmonary Arterial Compliance in Pulmonary Hypertension

    The normal pulmonary circulation is a low-pressure, high-compliance system. Pulmonary arterial compliance decreases in the presence of pulmonary hypertension because of increased extracellular matrix/collagen deposition in the pulmonary arteries. Loss of pulmonary arterial compliance has been consistently shown to be a predictor of increased mortality in patients with pulmonary hypertension, even more so than pulmonary vascular resistance in some studies. Decreased pulmonary arterial compliance causes premature reflection of waves from the distal pulmonary vasculature, leading to increased pulsatile right ventricular afterload and eventually right ventricular failure. Evidence suggests that decreased pulmonary arterial compliance is a cause rather than a consequence of distal small vessel proliferative vasculopathy. Pulmonary arterial compliance decreases early in the disease process even when pulmonary artery pressure and pulmonary vascular resistance are normal, potentially enabling early diagnosis of pulmonary vascular disease, especially in high-risk populations. With the recognition of the prognostic importance of pulmonary arterial compliance, its impact on right ventricular function, and its contributory role in the development and progression of distal small-vessel proliferative vasculopathy, pulmonary arterial compliance is an attractive target for the treatment of pulmonary hypertension.

    Full Text Available Idiopathic pulmonary fibrosis (IPF is a chronic progressive fibrotic lung disease associated with substantial morbidity and mortality. The objective of this study was to determine whether there is a peripheral blood protein signature in IPF and whether components of this signature may serve as biomarkers for disease presence and progression.We analyzed the concentrations of 49 proteins in the plasma of 74 patients with IPF and in the plasma of 53 control individuals. We identified a combinatorial signature of five proteins-MMP7, MMP1, MMP8, IGFBP1, and TNFRSF1A-that was sufficient to distinguish patients from controls with a sensitivity of 98.6% (95% confidence interval [CI] 92.7%-100% and specificity of 98.1% (95% CI 89.9%-100%. Increases in MMP1 and MMP7 were also observed in lung tissue and bronchoalveolar lavage fluid obtained from IPF patients. MMP7 and MMP1 plasma concentrations were not increased in patients with chronic obstructive pulmonary disease or sarcoidosis and distinguished IPF compared to subacute/chronic hypersensitivity pneumonitis, a disease that may mimic IPF, with a sensitivity of 96.3% (95% CI 81.0%-100% and specificity of 87.2% (95% CI 72.6%-95.7%. We verified our results in an independent validation cohort composed of patients with IPF, familial pulmonary fibrosis, subclinical interstitial lung disease (ILD, as well as with control individuals. MMP7 and MMP1 concentrations were significantly higher in IPF patients compared to controls in this cohort. Furthermore, MMP7 concentrations were elevated in patients with subclinical ILD and negatively correlated with percent predicted forced vital capacity (FVC% and percent predicted carbon monoxide diffusing capacity (DLCO%.Our experiments provide the first evidence for a peripheral blood protein signature in IPF to our knowledge. The two main components of this signature, MMP7 and MMP1, are overexpressed in the lung microenvironment and distinguish IPF from other chronic lung

    Invasive pulmonary aspergillosis is characterized by radiological signs allowing a correct diagnosis, including differentiation from pulmonary candidiasis, when they are associated with appropriate clinical symptoms (neutropenia and fever persisting despite broad-spectrum antibiotics). In particular the formation of a pulmonary mycetoma in a previously normal lung is one of these signs. Unlike a simple fungus ball (the saprophytic form of aspergillosis), the rounded density of invasive pulmonary aspergillosis consists of sequestrum of devitalized lung tissue owing to blood vessel invasion by Aspergillus hyphae. This morphologic phenomenon is demonstrated in the present case report and is discussed together with the other roentgenological signs of the invasive aspergillosis. (orig.) [de

    Full Text Available Background: Retinoblastomas account for 4% of malignancies in children, 1-2% of which are diffuse infiltrating retinoblastomas. Diffuse anterior retinoblastoma is rare and does not involve the retina. Here, we report on a diffuse anterior retinoblastoma with large sarcoidosis-like nodules on the iris that were responsive to anti-inflammatory therapy. Case: We present a 6-year-old girl who had anterior uveitis with white nodules on the iris and posterior surface of the cornea in her right eye. The nodules initially responded well to anti-inflammatory treatment. However, anterior segment optical coherence tomography (AS-OCT showed that the nodules gradually grew, shrinking the iris. We then collected the aqueous humor for diagnosis. A biopsy revealed clusters of small cells with a high nuclear-to-cytoplasm ratio with partial rosette formation. Therefore, we diagnosed diffuse anterior retinoblastoma without retinal involvement and performed enucleation of the right eye. The histopathology demonstrated undifferentiated cells similar to those seen on the biopsy, and tumor cells invaded the iris stroma, posterior surface of the cornea, ciliary body, and sclera. After the enucleation, she underwent chemotherapy and remains alive. Conclusion: A differential diagnosis of retinoblastoma should be considered when white nodules refractory to anti-inflammatory therapy occur in the eye, even in the absence of obvious retinal masses. AS-OCT findings are useful in assessing retinoblastoma.

    We have shown previously that input impedance of the pulmonary vasculature provides a comprehensive characterization of right ventricular afterload by including compliance. However, impedance-based compliance assessment requires invasive measurements. Here, we develop and validate a noninvasive method to measure pulmonary artery (PA) compliance using ultrasound color M-mode (CMM) Doppler tissue imaging (DTI). Dynamic compliance (C(dyn)) of the PA was obtained from CMM DTI and continuous wave Doppler measurement of the tricuspid regurgitant velocity. C(dyn) was calculated as: [(D(s) - D(d))/(D(d) x P(s))] x 10(4); where D(s) = systolic diameter, D(d) = diastolic diameter, and P(s) = systolic pressure. The method was validated both in vitro and in 13 patients in the catheterization laboratory, and then tested on 27 pediatric patients with pulmonary hypertension, with comparison with 10 age-matched control subjects. C(dyn) was also measured in an additional 13 patients undergoing reactivity studies. Instantaneous diameter measured using CMM DTI agreed well with intravascular ultrasound measurements in the in vitro models. Clinically, C(dyn) calculated by CMM DTI agreed with C(dyn) calculated using invasive techniques (23.4 +/- 16.8 vs 29.1 +/- 20.6%/100 mm Hg; P = not significant). Patients with pulmonary hypertension had significantly lower peak wall velocity values and lower C(dyn) values than control subjects (P < .01). C(dyn) values followed an exponentially decaying relationship with PA pressure, indicating the nonlinear stress-strain behavior of these arteries. Reactivity in C(dyn) agreed with reactivity measured using impedance techniques. The C(dyn) method provides a noninvasive means of assessing PA compliance and should be useful as an additional measure of vascular reactivity subsequent to pulmonary vascular resistance in patients with pulmonary hypertension.

    Objectives: Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk of pulmonary tuberculosis. However, detecting pulmonary tuberculosis may be difficult due to the underlying fibrosis. The aim of this report is to describe the radiological and clinical findings of pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis. Materials and methods: We reviewed 143 consecutive patients in whom IPF was diagnosed by either the histological or radio-clinical criteria. Among them, nine patients were histologically (n=2) or bacteriologically (n=7) confirmed to have active pulmonary tuberculosis. The location and patterns of pulmonary tuberculosis were examined on a thin section CT scan. Results: The most common thin section CT findings were subpleural nodules (n=6; mean diameter, 3.2 cm) and a lobar or segmental consolidation (n=3). The lesions were located most commonly in the right lower lobe (n=4). The incidence of tuberculosis in patients with idiopathic pulmonary fibrosis was more than five times higher than that of the general population. Conclusion: The atypical manifestation of pulmonary tuberculosis is common in patients with idiopathic pulmonary fibrosis, which may mimic lung cancer or bacterial pneumonia.

    Distributions of pulmonary blood flow per unit lung volume were measured in sitting patients with a radionuclide computed tomography (RCT) by intravenously administered Tc-99m macroaggregates of human serum albumin (MAA). Four different types of distribution were distinguished, among which a group referred as type 2 had a three zonal blood flow distribution as previously reported (West and co-workers, 1964). The pulmonary arterial pressure (Pa) and the venous pressure (Pv) were determined in this group of distribution. These values showed satifactory agreements with the pulmonary artery pressure (Par) and the capillary wedged pressure (Pcw) measured by Swan-Ganz catheter in eighteen supine patients. Those good correlations enable to establish a noninvasive methodology for measurement of pulmonary vascular pressures

    Pulmonary capillary haemangiomatosis (PCH) is a rare disorder of unknown aetiology, characterised by proliferating capillaries that invade the pulmonary interstitium, alveolar septae and the pulmonary vasculature. It is often mis-diagnosed as primary pulmonary hypertension and pulmonary veno-occlusive disease. Pulmonary capillary haemangiomatosis is a locally aggressive benign vascular neoplasm of the lung. We report the case of a 19-year-old female who was referred to us in the early post-partum period with severe pulmonary artery hypertension, which was diagnosed as PCH by open lung biopsy.

    Radioiodine may accumulate at sites of inflammation or infection. We have seen such accumulation in six thyroid cancer patients with a history of previously treated pulmonary tuberculosis. We also review the causes of false-positive radioiodine uptake in lung infection/inflammation. Eight foci of radioiodine uptake were seen on six iodine-123 diagnostic scans. In three foci, the uptake was focal and indistinguishable from thyroid cancer pulmonary metastases from thyroid cancer. In the remaining foci, the uptake appeared nonsegmental, linear or lobar, suggesting a false-positive finding. The uptake was unchanged, variable in appearance or non-persistent on follow-up scans and less extensive than the fibrocystic changes seen on chest radiographs. In the two patients studied, thyroid hormone level did not affect the radioiodine lung uptake and there was congruent gallium-67 uptake. None of the patients had any evidence of thyroid cancer recurrence or of reactivation of tuberculosis and only two patients had chronic intermittent chest symptoms. Severe bronchiectasis, active tuberculosis, acute bronchitis, respiratory bronchiolitis, rheumatoid arthritis-associated lung disease and fungal infection such as Allescheria boydii and aspergillosis can lead to different patterns of radioiodine chest uptake mimicking pulmonary metastases. Pulmonary scarring secondary to tuberculosis may predispose to localized radioiodine accumulation even in the absence of clinically evident active infection. False-positive radioiodine uptake due to pulmonary infection/inflammation should be considered in thyroid cancer patients prior to the diagnosis of pulmonary metastases. (orig.)

    Full Text Available Abstract Carcinosarcoma of the lung is a malignant tumor composed of a mixture of carcinoma and sarcoma elements. The carcinomatous component is most commonly squamous followed by adenocarcinoma. The sarcomatous component commonly comprises the bulk of the tumor and shows poorly differentiated spindle cell features. Foci of differentiated sarcomatous elements such as chondrosarcoma and osteosarcoma may be seen. Aspergillus pneumonia is the most common form of invasive aspergillosis and occurs mainly in patients with malignancy, immunocompromizing or debilitating diseases. Patients with Aspergillus pneumonia present with fever, cough, chest pain and occasionally hemoptysis. Tissue examination is the most reliable method for diagnosis, and mortality rate is high. We describe a case of primary carcinosarcoma of the lung concurrently occurring with invasive pulmonary aspergillosis in a 66-year old patient.

    The usefulness of bronchoalveolar lavage fluid (BALF) CD4/CD8 ratio for diagnosing sarcoidosis has been reported in many studies with variable results. Therefore, we performed a meta-analysis to estimate the overall diagnostic accuracy of BALF CD4/CD8 ratio based on the bulk of published evidence. Studies published prior to June 2015 and indexed in PubMed, OVID, Web of Science, Scopus and other databases were evaluated for inclusion. Data on sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were pooled from included studies. Summary receiver operating characteristic (SROC) curves were used to summarize overall test performance. Deeks's funnel plot was used to detect publication bias. Sixteen publications with 1885 subjects met our inclusion criteria and were included in this meta-analysis. Summary estimates of the diagnostic performance of the BALF CD4/CD8 ratio were as follows: sensitivity, 0.70 (95%CI 0.64-0.75); specificity, 0.83 (95%CI 0.78-0.86); PLR, 4.04 (95%CI 3.13-5.20); NLR, 0.36 (95%CI 0.30-0.44); and DOR, 11.17 (95%CI 7.31-17.07). The area under the SROC curve was 0.84 (95%CI 0.81-0.87). There was no evidence of publication bias. Measuring the BALF CD4/CD8 ratio may assist in the diagnosis of sarcoidosis when interpreted in parallel with other diagnostic factors. Copyright © 2016 The Authors. Published by Elsevier B.V.

    Pulmonary thromboendarterectomy surgery is the treatment of choice for patients with chronic thromboembolic pulmonary hypertension; extremely high pulmonary vascular resistance constitutes a risk factor for hospital mortality. The objective of this study was to analyze the immediate and long-term results of the surgical treatment of chronic thromboembolic pulmonary hypertension in patients with very severe pulmonary hypertension. Since February 1996, we performed 160 pulmonary thromboendarterectomies. We divided the patient population in 2 groups: group 1, which included 40 patients with pulmonary vascular resistance≥1090dyn/sec/cm -5 , and group 2, which included the remaining 120 patients. Hospital mortality (15 vs. 2.5%), reperfusion pulmonary edema (33 vs. 14%) and heart failure (23 vs. 3.3%) were all higher in group 1; however, after one year of follow-up, there were no significant differences in the clinical, hemodynamic and echocardiographic conditions of both groups. Survival rate after 5 years was 77% in group 1 and 92% in group 2 (P=.033). After the learning curve including the 46 first patients, there was no difference in hospital mortality (3.8 vs. 2.3%) or survival rate after 5 years (96.2% in group 1 and 96.2% in group 2). Pulmonary thromboendarterectomy is linked to significantly higher morbidity and mortality rates in patients with severe chronic thromboembolic pulmonary hypertension. Nevertheless, these patients benefit the same from the procedure in the mid-/long-term. In our experience, after the learning curve, this surgery is safe in severe pulmonary hypertension and no level of pulmonary vascular resistance should be an absolute counter-indication for this surgery.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is thought to be a rare complication of pulmonary embolism. However, it was recently demonstrated that CTEPH is more common than previously thought after pulmonary embolism. Without treatment, CTEPH is associated with a very high mortality rate. Making the correct diagnosis early is essential, because there is a potential curative treatment in the form of pulmonary thromboendarterectomy (PTE). Because of the unspecific clinical symptoms of CTEPH, the different imaging modalities play a crucial role in diagnosis making. Since the introduction of the multi-detector CT technology, CT has become an important part in the diagnostic work up of pulmonary embolism and CTEPH and is often used as a first-line diagnostic tool. CT is not only a reliable tool for the diagnosis of CTEPH, but also is helpful in estimating the operability of these patients. PTE is still associated with a mortality rate of about 10%. Particularly an insufficient decrease of the pulmonary vascular resistance after PTE leads to a very high mortality rate. Therefore, it is crucial to correlate the degree of the surgical accessible obstruction of the pulmonary vasculature with the degree of pulmonary hypertension in deciding for or against PTE. The aim of this review is to describe the CT findings in patients with CTEPH and their use in differentiating CTEPH from other diseases like acute pulmonary embolism and primary pulmonary hypertension. Moreover, the correlation of different CT imaging features with surgical success after PTE will be discussed. (orig.)

    The causes of pulmonary arterial hypertension (PAH) are diverse and include multiple congenital and acquired cardiac diseases as well as diseases primarily affecting the pulmonary vasculature, lung, pleura and chest wall. The traditional role of CT in evaluating PAH includes assessment of pulmonary vasculature and lung parenchyma with limited assessment of the heart. Advances in multidetector CT technology with improved spatial and temporal resolution now permit accurate delineation of cardiac morphology. CT pulmonary angiography (CTPA) is widely utilised in the workup of patients with suspected pulmonary vascular disease and can identify both pulmonary and cardiac causes. As the initial presentation for CTPA is often precipitated by nonspecific, unexplained symptoms and therefore undertaken by a general radiologist, it is important that a systematic approach to the interpretation of these studies, including cardiac evaluation, is routinely adopted. This paper reviews the CT evaluation in pulmonary hypertension with a particular focus on the cardiac causes, their subclassification into congenital systemic to pulmonary shunts and secondary to left heart disease, and their imaging features. It emphasises the use of a systematic approach to interpretation of CTPA examinations both in patients with known PAH and those with previously unsuspected disease. (orig.)

    Full Text Available Tae Hoon Kim, Jae Seung Lee, Sei Won Lee, Yeon-Mok Oh Department of Pulmonary and Critical Care Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Abstract: Postoperative pulmonary complications (PPCs are one of the most important causes of postoperative morbidity and mortality after abdominal surgery. Although chronic obstructive pulmonary disease (COPD has been considered a risk factor for PPCs, it remains unclear whether mild-to-moderate COPD is a risk factor. This retrospective cohort study included 387 subjects who underwent abdominal surgery with general anesthesia in a tertiary referral hospital. PPCs included pneumonia, pulmonary edema, pulmonary thromboembolism, atelectasis, and acute exacerbation of COPD. Among the 387 subjects, PPCs developed in 14 (12.0% of 117 patients with mild-to-moderate COPD and in 13 (15.1% of 86 control patients. Multiple logistic regression analysis revealed that mild-to-moderate COPD was not a significant risk factor for PPCs (odds ratio [OR] =0.79; 95% confidence interval [CI] =0.31–2.03; P=0.628. However, previous hospitalization for respiratory problems (OR =4.20; 95% CI =1.52–11.59, emergency surgery (OR =3.93; 95% CI =1.75–8.82, increased amount of red blood cell (RBC transfusion (OR =1.09; 95% CI =1.05–1.14 for one pack increase of RBC transfusion, and laparoscopic surgery (OR =0.41; 95% CI =0.18–0.93 were independent predictors of PPCs. These findings suggested that mild-to-moderate COPD may not be a significant risk factor for PPCs after abdominal surgery.Keywords: postoperative pulmonary complications, spirometry, risk factor, abdominal surgery, postoperative complications, postoperative care

He had a history of previous treatment for tuberculosis. His laboratory data were normal. Bronchoscopy and CT-guided percutaneous transthoracic fine needle aspiration cytology were inconclusive. The diagnosis was revealed after the histopathological examination of an open lung biopsy.

    Anomalous pulmonary venous return is an uncommon congenital malformation, and may be partial or total. Partial anomalous pulmonary venous return (PAPVR) is more common than total anomalous pulmonary venous return, and is often associated with other congenital cardiac anomalies. Whilst many patients with PAPVR remain asymptomatic, some may present in later age with symptoms related to left-to-right shunt, right heart failure and pulmonary hypertension. We report two cases of PAPVR detected on Computed Tomography Pulmonary Angiogram (CTPA) for the work up of pulmonary hypertension. The cases demonstrate that, although uncommon, partial anomalous pulmonary venous return can be a contributing factor to pulmonary hypertension and pulmonary veins should be carefully examined when reading a CTPA study.

  1. S WAVE IN PULMONARY EMBOLISM, A NEW ECG SIGN TO AID THROMBOLYSIS

    Full Text Available Acute pulmonary embolism is a devastating disease that often leads to mortality . Previous investigators have found that thrombolysis reduces mortality in men but not significantly in women with pulmonary embolism. Many of the previous studies are with tenecteplase and alteplase. Here, we describe intra - venous thrombolysis with streptokinase in seven patients with pulmonary embolism who survived including two women. Further, we have one patient who had a new onset of S wave in lead I which subsequently disappeared after embolectomy. We also comment on the usefulness of shock sign in 2 deciding on thrombolysis .We propose a new sign for noninvasive assessment of need for thrombolysis in pulmonary embolism. New onset S wave in Lead I in pulmonary embolism can be used as a new sign for deciding the need for thrombolysis. When added to the shock sign it can be used in the emergency deparment to decide the need for thrombolysis. Further, there are no clear end points as to when to stop thrombolysis. In all 4 patients we switched to heparin when spontaneous bleeding or oozing started. In all 4 patients subsequent CT scans showed that the patient has mild to moderate resolution of the pulmonary embolism and patients remained stable and have been discharged and are under regular follow up. Hence we propose that bleeding can be used as an end point for thrombolysis in acute pulmonary embolism. We also describe a patient who had new onset S wave that disappeared after successful pulmonary embolectomy. Probably, the S wave is a marker of main pulmonary artery branch occlusions.

    Full Text Available Pulmonary actinomycosis is a rare disease that is often misdiag-nosed as tuberculosis or lung cancer. Actinomyces graevenitzii is a relatively new recognized Actinomyces species isolated from various clinical samples. The authors report a case of pulmonary actinomycosis caused by A graevenitzii. A computed tomography examination revealed an excavated consolidation in the middle right lobe of a previously healthy young man who presented with a long history of moderate cough. Cultures of the bronchoalveolar lavage fluid confirmed the diagnosis of pulmonary abscess caused by A gravenitzii. At the three-month follow-up consultation and, after six weeks of high-dose amoxicillin, the pulmonary lesion had completely disappeared.

    Pulmonary vascular arterial remodeling is an integral and well-understood component of pulmonary hypertension (PH). In contrast, morphological alterations of pulmonary veins in PH are scarcely described. Explanted lungs (n = 101) from transplant recipients with advanced chronic obstructive...... pulmonary disease (COPD) and idiopathic pulmonary arterial hypertension (IPAH) were analyzed for venous vascular involvement according to a pre-specified, semi-quantitative grading scheme, which categorizes the intensity of venous remodeling in three groups of incremental severity: venous hypertensive (VH......) grade 0 = characterized by an absence of venous vascular remodeling; VH grade 1 = defined by a dominance of either arterialization or intimal fibrosis; and VH grade 2 = a substantial composite of arterialization and intimal fibrosis. Patients were grouped according to clinical and hemodynamic...

    The effects of chronic increase in pulmonary blood flow and chronic pulmonary hypertension on regional pulmonary blood volume was measured in two groups of patients. One group of patients had intracardiac, left-to-right shunts without appreciable pulmonary hypertension, and the other consisted of patients with Eisenmenger's syndrome or primary pulmonary hypertension, i.e. patients with normal or reduced blood flow and severe pulmonary hypertension. A technique based on positron tomography was used to measure lung density (by transmission scanning) and regional pulmonary blood volume (after inhalation of /sup 11/CO). The distribution of pulmonary blood volume was more uniform in patients with chronic increase in pulmonary blood flow than in normal subjects. There were also indications of an absolute increase in intrapulmonary blood volume by about 15%. In patients with chronic pulmonary arterial hypertension, the distribution of pulmonary blood volume was also abnormally uniform. There was, however, no indication that overall intrapulmonary blood volume was substantially different from normal subjects. The abnormally uniform distribution of pulmonary blood volume can be explained by recruitment and/or dilatation of vascular beds. Intrapulmonary blood volume appears to be increased in patients with intracardiac, left-to-right shunts. With the development of pulmonary hypertension, intrapulmonary blood volume falls, which may be explained by reactive changes in the vasculature and/or obliteration of capillaries

  6. When a pulmonary embolism is not a pulmonary embolism: a rare case of primary pulmonary leiomyosarcoma

    2015-12-01

    Full Text Available Arterial leiomyosarcomas account for up to 21% of vascular leiomyosarcomas, with 56% of arterial leiomyosarcomas occurring in the pulmonary artery. While isolated cases of primary pulmonary artery leiomyosarcoma document survival up to 36 months after treatment, these uncommon, aggressive tumors are highly lethal, with 1-year survival estimated at 20% from the onset of symptoms. We discuss a rare case of a pulmonary artery leiomyosarcoma that was originally diagnosed as a pulmonary embolism (PE. A 72-year-old Caucasian female was initially diagnosed with ‘saddle pulmonary embolism’ based on computerized tomographic angiography of the chest 2 months prior to admission and placed on anticoagulation. Dyspnea escalated, and serial computed tomography scans showed cardiomegaly with pulmonary emboli involving the right and left main pulmonary arteries with extension into the right and left upper and lower lobe branches. An echocardiogram on admission showed severe pulmonary hypertension with a pulmonary artery pressure of 82.9 mm Hg, and a severely enlarged right ventricle. Respiratory distress and multiorgan failure developed and, unfortunately, the patient expired. Autopsy showed a lobulated, yellow mass throughout the main pulmonary arteries measuring 13 cm in diameter. The mass extended into the parenchyma of the right upper lobe. On microscopy, the mass was consistent with a high-grade primary pulmonary artery leiomyosarcoma. Median survival of patients with primary pulmonary artery leiomyosarcoma without surgery is one and a half months, and mortality is usually due to right-sided heart failure. Pulmonary artery leiomyosarcoma is a rare but highly lethal disease commonly mistaken for PE. Thus, we recommend clinicians to suspect this malignancy when anticoagulation fails to relieve initial symptoms. In conclusion, early detection and suspicion of pulmonary artery leiomyosarcoma should be considered in patients refractory to anticoagulation

    Pulmonary histiocytosis X is an idiopathic disease which is and uncommon but important cause of pulmonary fibrosis in young adults. Chest radiographs and high resolution computed tomographic (HRCT) scans of the lungs of 7 patients diagnosed as pulmonary histiocytosis X were examined retrospectively. The authors reviewed the pathologic, clinical and radiographic features of pulmonary histiocytosis X, focusing on differential diagnosis and disease progression. Pulmonary histiocytosis X can be suspected on the basis of chest radiographic findings; predominantly upper lobe nodules and cysts present an increased sensitivity and are virtually pathognomonic of this disorder. Chest HRCT allows good assessment of the evolution of pulmonary histiocytosis X and is also valuable in distinguishing histiocytosis from other disorders that produces nodules or cysts. (author)

    2013-01-01

    Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

    diagnostic criteria for cardiogenic pulmonary oedema was used as gold standard. RESULTS: A total of 40 patients were included in the study. Feasibility of PLUS was 100 % and median time used was 3 min. The gold standard diagnosed 18 (45.0 %) patients with cardiogenic pulmonary oedema. The diagnostic accuracy......: The sensitivity of PLUS is high, making it a potential tool for ruling-out cardiogenic pulmonary. The observed specificity was lower than what has been described in previous studies. CONCLUSIONS: Performed, as part of a physician based prehospital emergency service, PLUS seems fast and highly feasible in patients...... with respiratory failure. Due to its diagnostic accuracy, PLUS may have potential as a prehospital tool, especially to rule out cardiogenic pulmonary oedema....

    1985-01-01

    Pulmonary arteriography was performed by digital subtraction angiographic (DSA) method in 10 patients with cyanotic heart disease associated with pulmonary stenosis or pulmonary atresia. Ten patients consisted of five patients with tetralogy of Fallot, three with single ventricle and pulmonary stenosis, and two with pseudotruncus arteriosus. Hepato-clavicular position was taken in four patients. Pulmonary artery and its main branches were opacified and recognized clearly, and their diameter could be measured accurately with a small amount of contrast medium. There was a good correlation between the diameter of pulmonary artery measured by DSA and that measured by conventional pulmonary arteriography. DSA is a useful method for evaluating the size and the stenosis of pulmonary artery especially in small cyanotic infants. (author)

    A retrospective study of 15 patients with primary tumors, 13 of the lung and 2 breast cancers, treated in the Hospital Santa Cruz/Beneficiencia Portuguesa de Niteroi, RJ, in the period comprised from February 1991 to October 1996, was done. The pulmonary radiotherapy effects were observed in two clinical presentations - acute (radiation pneumonitis) and chronic (radiation fibrosis) -, both depending upon the radiotherapy doses, the radiation area, the individual susceptibility and the previous chemotherapy. Signs of pulmonary fibrosis were found in 73.3% of the patients, pneumonitis in 20.0% and absence of changes after radiation in 6.6%. Computed tomography was an excellent noninvasive diagnostic method in demonstrating radiotherapy-induced pulmonary changes, more evident in high-resolution technique scans. (author)

    This is a case report of a young woman who presented with an extensive pulmonary embolism and echocardiographic evidence of right ventricular dysfunction. Although hemodynamically stable, the patient\\'s clinical condition failed to improve with standard heparin anticoagulation. Successful local catheter-directed thrombolysis was performed over an extended period of 48 h with regular monitoring of response to therapy by computed tomography-pulmonary angiography and echocardiography. To our knowledge, treatment of a pulmonary embolism by catheter-directed thrombolytic infusion over an extended period of 48 h has not previously been described.

    Pulmonary capillary pressure (PCP), together with the time constants of the various vascular compartments, define the dynamics of the pulmonary vascular system. Our objective in the present study was to estimate PCPs and time constants of the vascular system in patients with idiopathic pulmonary arterial hypertension (IPAH), and compare them with these measures in patients with acute respiratory distress syndrome (ARDS). We conducted the study in two groups of patients with pulmonary hypertension: 12 patients with IPAH and 11 with ARDS. Four methods were used to estimate the PCP based on monoexponential and biexponential fitting of pulmonary artery pressure decay curves. PCPs in the IPAH group were considerably greater than those in the ARDS group. The PCPs measured using the four methods also differed significantly, suggesting that each method measures the pressure at a different site in the pulmonary circulation. The time constant for the slow component of the biexponential fit in the IPAH group was significantly longer than that in the ARDS group. The PCP in IPAH patients is greater than normal but methodological limitations related to the occlusion technique may limit interpretation of these data in isolation. Different disease processes may result in different times for arterial emptying, with resulting implications for the methods available for estimating PCP.

    Choroidal neovascular membrane (CNV) may occur in patients with posterior uveitis. Treatment of patients with corticosteroids induces regression of the inflammation in the posterior pole with downregulation of many cytokines including vascular endothelial growth factors. We report herewith, a case of biopsy proven sarcoidosis that developed posterior uveitis and peripapillary CNV membrane and subretinal hemorrhage with fluid. The patient was treated with systemic steroids. She demonstrated progressive regression of the CNV membrane and complete resolution of the subretinal hemorrhage and fluids. In conclusion, control of the posterior segment inflammation is crucial in the resolution of the CNV membrane in uveitis and the intravitreal anti-vascular endothelial growth factor may not be always indicated.

    The aim of this study is to describe the prevalence, anatomy, associations and clinical impact of partial anomalous pulmonary venous return in patients with Turner syndrome. All Turner patients who presented at our Turner clinic, between January 2007 and October 2015 were included in this study and underwent ECG, echocardiography and advanced imaging such as cardiac magnetic resonance or computed tomography as part of their regular clinical workup. All imaging was re-evaluated and detailed anatomy was described. Partial anomalous pulmonary venous return was diagnosed in 24 (25%) out of 96 Turner patients included and 14 (58%) of these 24 partial anomalous pulmonary venous return had not been reported previously. Right atrial or ventricular dilatation was present in 11 (46%) of 24 partial anomalous pulmonary venous return patients. When studied with advanced imaging modalities and looked for with specific attention, PAPVR is found in 1 out of 4 Turner patients. Half of these patients had right atrial and/or ventricular dilatation. Evaluation of pulmonary venous return should be included in the standard protocol in all Turner patients. Copyright © 2017.

    Pediatric cardiac surgery, especially for small neonates, typically requires blood products to counter hemodilution during cardiopulmonary bypass. Children with congenital heart defects whose families adhere to faith-based proscriptions against blood transfusion therefore represent a challenging surgical population. Here, we report the case of a ten-day-old, 3.6-kg patient of Jehovah's Witness faith, who was diagnosed with unilateral pulmonary artery discontinuity, bilateral patent ductus arteriosus, and an otherwise structurally normal heart. Pulmonary artery reimplantation was successfully performed without giving blood products. This case adds to previous reports of successful bloodless cardiac surgery in neonates and describes the specific strategies that contributed to successful pulmonary artery reimplantation. © The Author(s) 2015.

    To expand the search for central pulmonary arteries in six patients with absence of cardiac-pulmonary continuity, computerized axial tomography (CAT) of the chest was performed. The CAT scans were compared with previous arteriograms and pulmonary vein wedge angiograms. Three patients with type IV truncus arteriosus were studied, and none had a central, right or left pulmonary artery on CAT scan. However, two patients with tetralogy of Fallot with pulmonary atresia and a patent ductus arteriosus to the right lung demonstrated the presence of a left pulmonary artery. In addition, one child with truncus arteriosus with ''absent'' left pulmonary artery demonstrated a left pulmonary artery on the CAT scan. The CAT scan may therefore enhance our ability to search for disconnected pulmonary arteries in children with complex cyanotic congenital heart disease.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is an underdiagnosed potential complication of acute or recurrent pulmonary thromboembolic disease. Multiple studies suggest that up to 5% of patients with acute pulmonary thromboembolic disease go on to develop CTEPH. The prognosis of untreated CTEPH is poor, but advances in medical and surgical treatments over the past few decades have improved patient outcomes. The gold standard and curative treatment for CTEPH is pulmonary endarterectomy; however, some patients are inoperable and others who have undergone pulmonary endarterectomy experience persistent or recurrent pulmonary hypertension despite medical therapy. In recent years, balloon pulmonary angioplasty has emerged as a primary and adjunctive treatment for these CTEPH patients at expert or specialized centers. This review outlines an approach to balloon pulmonary angioplasty for CTEPH, including clinical presentation and evaluation; patient selection and indications; treatment planning; equipment and technique; overcoming technical challenges; recognition and management of complications; postprocedural care and clinical follow-up; and expected outcomes.

    Sarcoidosis is a systemic chronic inflammatory disease of unknown aetiology, characterised by granulomatous lesions with heterogeneous clinical manifestations affecting multiple organs and tissues. Although the respiratory system is most commonly affected, the disease may also present with bone lesions. We report the case of a 31-year old woman who presented with low back pain and no history of cancer and who was found to have suspicious lesions involving the entire spine on magnetic resonance imaging (MRI). The patient underwent 18 F-fluorodeoxyglucose (FDG) PET/CT to search for a primary tumour and for staging purposes. 18 F-FDG PET/CT revealed a pattern of hypermetabolic activity in widespread skeletal lesions and in a single left cervical lymph node. The primary tumour was not found, thus suggesting a haematologic disorder. Subsequent biopsies of a cervical lymph node and of bone tissue from L4 revealed active sarcoidosis with no evidence of cancer. This underlines the importance of considering all alternatives when hypermetabolic lesions are found on 18 F-FDG PET/CT. Furthermore, 18 F-FDG PET can be very useful to indicate accessible sites for guiding fine-needle aspiration cytology (FNAC)

    A comparative analysis of pulmonary perfusion scanning through cardiac catheterization of 57 patients including 32 patients with congenital heart disease, 8 patients with chronic pulmonary thromboembolism and 7 patients with primary pulmonary hypertension is reported. The lung scintigram obtained with In-113m or Tc-99m-MAA represents the distribution of pulmonary blood. It has been found that the lung scintigram was abnormal in patients of congenital heart disease with pulmonary hypertension (i. e. pulmonary artery pressure between 41-80 mmHg) and the extent of radoiactive regional defects is proportional to the level of pulmonary hypertension. The results of the analysis indicated that pulmonary perfusion scanning being a noninvasive technique would be a useful method in evaluating the level of pulmonary hypertension in patients with left to right shunt before and after surgical operation

    Right ventricular failure is a leading cause of mortality in patients with pulmonary arterial hypertension (PAH). However, up to 25% of such patients die unexpectedly, without warning signs of hemodynamical decompensation. We previously documented that pulmonary artery (PA) dilatation significantly increases the risk of those deaths. Some of them may be due to dissection of PA resulting in cardiac tamponade. However, direct confirmation of this mechanism is difficult as most of such deaths occur outside hospitals. We present 4 patients with severe PAH and PA dilatation in whom PA dissection has been confirmed. Three patients had IPAH, one had PAH associated with congenital heart disease. All patients had mean pulmonary artery pressure (PAP) > 50 mmHg at diagnosis and dissection occurred late in the course of apparently well controlled disease (6 to 14 years). Several clinical elements were common to our patients - high systolic PAP, long lasting PH, progressive dilatation of PA to more than 50 mm with chest pain prior to dissection. However, clinical course followed three different patterns: sudden death due to cardiac tamponade, hemopericarditis caused by blood leaking from dissected aneurysm with imminent but not immediate cardiac tamponade, or chronic asymptomatic PA dissection. Indeed, two of our patients are alive and on lung transplantation waiting list for more than 2 years now. Further research is needed to suggest optimal management strategies for patients with stable PAH but significantly dilated proximal pulmonary arteries or confirmed PA dissection depending on the clinical presentation and expected outcome.

    The aim was to study the overall content and organisational aspects of pulmonary rehabilitation programmes from a global perspective in order to get an initial appraisal on the degree of heterogeneity worldwide. A 12-question survey on content and organisational aspects was completed by representatives of pulmonary rehabilitation programmes that had previously participated in the European Respiratory Society (ERS) COPD Audit. Moreover, all ERS members affiliated with the ERS Rehabilitation and Chronic Care and/or Physiotherapists Scientific Groups, all members of the American Association of Cardiovascular and Pulmonary Rehabilitation, and all American Thoracic Society Pulmonary Rehabilitation Assembly members were asked to complete the survey via multiple e-mailings. The survey has been completed by representatives of 430 centres from 40 countries. The findings demonstrate large differences among pulmonary rehabilitation programmes across continents for all aspects that were surveyed, including the setting, the case mix of individuals with a chronic respiratory disease, composition of the pulmonary rehabilitation team, completion rates, methods of referral and types of reimbursement. The current findings stress the importance of future development of processes and performance metrics to monitor pulmonary rehabilitation programmes, to be able to start international benchmarking, and to provide recommendations for international standards based on evidence and best practice.

    Pulmonary hematoma is a rare cause of a pulmonary nodule. Mostly it results from penetrating or blunt chest injuries. The case of a patient is reported, whose chest X-ray showed a pulmonary nodule suspected of malignancy. This patient was maintained permanently on anticoagulants (warfarin derivates) after cardiac valve replacement with a prosthesis. A definite diagnosis could not be established by non-invasive methods. A needle biopsy of the lung was impracticable because of the location of the pulmonary lesion; an exploratory thoracotomy could not be carried out due to a general indication of nonoperability. Control examinations showed that the pulmonary nodule had vanished completely within four months. In consideration of the patient's clinical situation it can be concluded that the pulmonary lesion was caused by a hematoma of the lung. (orig.) [de

    We measured the distribution of blood flow to the right (R) and left lung (L) by means of pulmonary perfusion imaging and calculated pulmonary vascular resistance (Rp) in 13 patients, whose right and left pulmonary artery pressures were different by 2 to 9 mmHg due to pulmonary arterial distortion (5 interruption, 8 stenosis). The right lung/left lung blood flow ratio was determined and from the ratio and the total pulmonary blood flow, which was determined using the Fick's principle, the absolute values of right and left pulmonary blood flow were calculated. Using the right and left pulmonary blood flow and the right and left pulmonary arterial pressures, right and left pulmonary vascular resistance were calculated, separately. Vascular resistance of the whole lung (Rp) was then calculated using the following equation. 1/(Rp of total lung)=1/(Rp of right lung)+1/(Rp of left lung). Rp calculated from this equation was 1.8+/-0.8 U·m 2 and all values were less than 3 U·m 2 (range 0.3-2.8). Rp estimated from the conventional method using the total pulmonary blood flow and pulmonary arterial pressures, without using the right/left blood flow ratio, ranging from 0.4 to 3.8 U·m 2 and 5 of 13 patients showed Rp>3 U·m 2 . All patients underwent Fontan operation successfully. These data indicated that this method is useful to estimate Rp and to determine the indication of Fontan operation in patients with pulmonary arterial distortions. (author)

    Full Text Available Background: In South Africa, pulmonary tuberculosis (PTB remains a problem of epidemic proportions. Despite evidence demonstrating persistent lung impairment after PTB cure, few population-based South African studies have investigated this finding. Pulmonary rehabilitation post-cure is not routinely received. Objectives: To determine the effects of PTB on lung function in adults with current or past PTB. To determine any association between PTB and chronic obstructive pulmonary disease (COPD. Methods: This study was observational and cross-sectional in design. Participants (n = 55 were included if they were HIV positive on treatment, had current PTB and were on treatment, and/or had previous PTB and completed treatment or if they were healthy adult subjects with no history of PTB. A sample of convenience was used with participants coming from a similar socio-economic background and undergoing spirometry testing. Multiple regression analyses were conducted on each lung function variable. Results: Compared to normal percentage-predicted values, forced expiratory volume in 1 second (FEV1 , forced vital capacity (FVC and FEV1 :FVC were significantly reduced in those with current PTB by 23.39%, 15.99% and 6.4%, respectively. Both FEV1 and FVC were significantly reduced in those with past PTB by 11.76% and 10.79%, respectively. There was no association between PTB and COPD – those with previous PTB having a reduced FEV1 :FVC (4.88% less than the norm, which was just short of significance (p = 0.059. Conclusions: Lung function is reduced both during and after treatment for PTB and these deficits may persist. This has implications regarding the need for pulmonary rehabilitation even after medical cure. Keywords: Lung function, pulmonary, tuberculosis

    Alveoli in the hilar region comprise the peripheral area containing daughter branches from subsegmental or one more divisional peripheral bronchi. Pulmonary perfusion in hilar region was examined by SPECT (single photon emission CT) in ten normal volunteers. ROI (region of interest) in the axial images were set in the hilar region, the upper, middle and lower lung fields with 10.8 mm thickness. Counts/one pixel (C/P) were calculated in these ROI. There was a tendency of C/P increase from upper to lower lung field. And there were no significant differences in C/P increase between hilar region and other axial fields. In the chronic obstructive pulmonary diseases, however, ventilation studies in the previous reports using Xe dynamic CT or PET (positron emission tomography) showed differences between outer region and hilar region. This method will be expected to evaluate the pulmonary perfusion not only in the whole lung but in different lung areas, including the hilar region in the chronic obstructive pulmonary diseases.

    2016-01-01

    Full Text Available Pulmonary artery dissection is extremely rare but it is a really life-threatening condition when it happens. Most patients die suddenly from major bleeding or tamponade caused by direct rupture into mediastinum or retrograde into the pericardial sac. What we are reporting is a rare case of a 46-year-old female patient whose pulmonary artery dissection involves both the pulmonary valve and right pulmonary artery. The patient had acute chest pain and severe dyspnea, and the diagnosis of pulmonary artery dissection was confirmed by ultrasonography and CT angiography. Moreover, its etiology, clinical manifestations, and management are also discussed in this article.

    Bronchoalveolar lavage (BAL) is a pulmonary sampling technique for characterization of drug concentrations in epithelial lining fluid and alveolar cells. Two hypothetical drugs with different pulmonary distribution rates (fast and slow) were considered. An optimized BAL sampling design was generated assuming no previous information regarding the pulmonary distribution (rate and extent) and with a maximum of two samples per subject. Simulations were performed to evaluate the impact of the number of samples per subject (1 or 2) and the sample size on the relative bias and relative root mean square error of the parameter estimates (rate and extent of pulmonary distribution). The optimized BAL sampling design depends on a characterized plasma concentration time profile, a population plasma pharmacokinetic model, the limit of quantification (LOQ) of the BAL method and involves only two BAL sample time points, one early and one late. The early sample should be taken as early as possible, where concentrations in the BAL fluid ≥ LOQ. The second sample should be taken at a time point in the declining part of the plasma curve, where the plasma concentration is equivalent to the plasma concentration in the early sample. Using a previously described general pulmonary distribution model linked to a plasma population pharmacokinetic model, simulated data using the final BAL sampling design enabled characterization of both the rate and extent of pulmonary distribution. The optimized BAL sampling design enables characterization of both the rate and extent of the pulmonary distribution for both fast and slowly equilibrating drugs.

    The authors performed retrograde pulmonary arteriography by means of a pulmonary venous wedge injection in 10 patients with no demonstrable intrapericardial pulmonary arteries by 'conventional' angiographic techniques. In all cases but one, the procedure demonstrated the feasibility of a further operation. No complications were observed. Retrograde pulmonary arteriography is an important additional method for determining the existence of surgically accessible pulmonary arteries when other techniques have failed. (Auth.)

    Objective: To probe into the value of MR imaging in evaluating the pulmonary artery hemodynamics and pulmonary artery pressure in acute massive pulmonary embolism. Methods: MR studies were performed in 21 patients with acute massive pulmonary embolism (diagnosed by contrast enhanced MR pulmonary angiography) and 20 healthy volunteers. The pulmonary artery hemodynamic parameters, such as the diameters of main and right pulmonary artery, peak velocity, average velocity, flow volume, flow patterns, and ejection acceleration time in main pulmonary artery were measured. The findings in patients and volunteers were compared. The hemodynamic parameters in patients were correlated with mean pulmonary artery pressure acquired with right heart catheterization. Results: The diameters of main pulmonary artery (2.93 vs 2.52 cm) and right pulmonary artery (2.49 vs 1.92 cm) in patients and volunteers showed significant differences (t=3.55, P<0.01 and t=4.19, P<0.01, respectively); Peak velocity (85.29 vs 100.63 cm/s), average velocity (11.00 vs 17.12 cm/s), flow volume (89.15 vs 98.96 ml/s), and ejection acceleration time (105.09 vs 163.85 ms) in main pulmonary artery were significantly different between patients and volunteers (t values were 2.89, 6.37, 2.21, and 9.46, respectively; P values were 0.01, <0.01, 0.03, and <0.01, respectively). The peak velocity-time curve of main pulmonary artery acquired with velocity encoded cine of MR in patients demonstrated earlier and lower peak velocity as well as abnormal retrograde flow. In addition, linear correlations were seen between the mean pulmonary pressure and the diameter of main pulmonary artery (r=0.62, P=0.001), diameter of right pulmonary artery (r=0.63, P=0.001), and ejection acceleration time (r=-0.55, P=0.005). Conclusion: MR imaging is a promising technique not only for the detection of pulmonary thromboemboli but also for the evaluation of hemodynamic parameters in pulmonary hypertension. (author)

    Sarcoidosis is a systemic chronic inflammatory disease of unknown aetiology, characterised by granulomatous lesions with heterogeneous clinical manifestations affecting multiple organs and tissues. Although the respiratory system is most commonly affected, the disease may also present with bone lesions. We report the case of a 31-year old woman who presented with low back pain and no history of cancer and who was found to have suspicious lesions involving the entire spine on magnetic resonance imaging (MRI). The patient underwent {sup 18}F-fluorodeoxyglucose (FDG) PET/CT to search for a primary tumour and for staging purposes. {sup 18}F-FDG PET/CT revealed a pattern of hypermetabolic activity in widespread skeletal lesions and in a single left cervical lymph node. The primary tumour was not found, thus suggesting a haematologic disorder. Subsequent biopsies of a cervical lymph node and of bone tissue from L4 revealed active sarcoidosis with no evidence of cancer. This underlines the importance of considering all alternatives when hypermetabolic lesions are found on {sup 18}F-FDG PET/CT. Furthermore, {sup 18}F-FDG PET can be very useful to indicate accessible sites for guiding fine-needle aspiration cytology (FNAC)

    We previously demonstrated that surfactant dilution and inhibition occur immediately after pulmonary artery flushing with hypothermic modified Euro-Collins solution. Consequently, we speculated that increased capillary permeability contributed to these surfactant changes. To test this hypothesis, we evaluated the effects of hypothermic pulmonary artery flushing on the pulmonary capillary filtration coefficient (Kfc), and additionally performed a biochemical analysis of surfactant. We used a murine isolated, perfused lung model to measure the pulmonary capillary filtration coefficient and hemodynamic parameters, to determine the wet to dry weight ratio, and to evaluate surfactant by biochemical analysis of lung lavage fluid. We defined three study groups. In group I (controls), we harvested lungs without hypothermic pulmonary artery flushing, and measured Kfc immediately. In group II (in situ flush), we harvested lungs after hypothermic pulmonary artery flushing with modified Euro-Collins solution, and then measured Kfc. Experiments in groups I and II were designed to evaluate persistent changes in Kfc after pulmonary artery flushing. In group III (ex vivo flush), we flushed lungs ex vivo to evaluate transient changes in Kfc during hypothermic pulmonary artery flushing. Groups I and II did not differ significantly in capillary filtration coefficient and hemodynamics. Group II showed significant alterations on biochemical surfactant analysis and a significant increase in wet-to-dry weight ratio, when compared with group I. In group III, we observed a significant transient increase in capillary filtration coefficient during pulmonary artery flushing. Hypothermic pulmonary artery flushing transiently increases the capillary filtration coefficient, leads to an increase in the wet to dry weight ratio, and induces biochemical surfactant changes. These findings could be explained by the effects of hypothermic modified Euro-Collins solution on pulmonary capillary

    The purpose of this time-domain study was to compare pulmonary artery (PA) pulse pressure and wave reflection in chronic pulmonary thromboembolism (CPTE) and primary pulmonary hypertension (PPH). Pulmonary artery pressure waveform analysis provides a simple and accurate estimation of right ventricular afterload in the time-domain. Chronic pulmonary thromboembolism and PPH are both responsible for severe pulmonary hypertension. Chronic pulmonary thromboembolism and PPH predominantly involve proximal and distal arteries, respectively, and may lead to differences in PA pressure waveform. High-fidelity PA pressure was recorded in 14 patients (7 men/7 women, 46 +/- 14 years) with CPTE (n = 7) and PPH (n = 7). We measured thermodilution cardiac output, mean PA pressure (MPAP), PA pulse pressure (PAPP = systolic - diastolic PAP) and normalized PAPP (nPAPP = PPAP/MPAP). Wave reflection was quantified by measuring Ti, that is, the time between pressure upstroke and the systolic inflection point (Pi), deltaP, that is, the systolic PAP minus Pi difference, and the augmentation index (deltaP/PPAP). At baseline, CPTE and PPH had similar cardiac index (2.4 +/- 0.4 vs. 2.5 +/- 0.5 l/min/m2), mean PAP (59 +/- 9 vs. 59 +/- 10 mm Hg), PPAP (57 +/- 13 vs. 53 +/- 13 mm Hg) and nPPAP (0.97 +/- 0.16 vs. 0.89 +/- 0.13). Chronic pulmonary thromboembolism had shorter Ti (90 +/- 17 vs. 126 +/- 16 ms, p PPAP (0.26 +/- 0.01 vs. 0.09 +/- 0.07, p < 0.01). Our study indicated that: 1) CPTE and PPH with severe pulmonary hypertension had similar PA pulse pressure, and 2) wave reflection is elevated in both groups, and CPTE had increased and anticipated wave reflection as compared with PPH, thus suggesting differences in the pulsatile component of right ventricular afterload.

    REMEHIP is a prospective, multicentre registry on pulmonary hypertension. The main objective will be to identify the clinical profile, medical care, therapeutic trends and outcomes in adult and pediatric Mexican patients with well-characterized pulmonary hypertension. REMEHIP a multicenter registry began in 2015 with a planned recruitment time of 12 months and a 4-year follow-up. The study population will comprise a longitudinal cohort study, collecting data on patients with prevalent and incident pulmonary hypertension. Will be included patients of age >2 years and diagnosis of pulmonary hypertension by right heart catheterization within Group 1 and Group 4 of the World Health Organization classification. The structure, data collection and data analysis will be based on quality current recommendations for registries. The protocol has been approved by institutional ethics committees in all participant centers. All patients will sign an informed consent form. Currently in Mexico, there is a need of observational registries that include patients with treatment in the everyday clinical practice so the data could be validated and additional information could be obtained versus the one from the clinical trials. In this way, REMEHIP emerges as a link among randomized clinical trials developed by experts and previous Mexican experience. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez.

    2008-01-01

    Pulmonary function tests in idiopathic pulmonary fibrosis characteristically show a restrictive pattern, resulting from reduction of pulmonary compliance due to diffuse fibrosis. Conversely, an obstructive pattern with hyperinflation results in emphysema by loss of elastic recoil, expiratory collapse of the peripheral airways and air trapping. Previous reports suggest that when both diseases coexist, pulmonary volumes are compensated and a smaller than expected reduction or even normal lung volumes can be found. We report 4 male patients of 64, 60, 73 and 70 years, all with heavy cigarette smoking history and progressive breathlessness. Three of them had severe limitation in their quality of life. All four showed advanced lung interstitial involvement, at high resolution CT scan, fibrotic changes predominantly in the subpleural areas of lower lung fields and concomitant emphysema in the upper lobes. Emphysema and pulmonary fibrosis was confirmed by open lung biopsy in one patient. The four patients showed normal spirometry and lung volumes with severe compromise of gas exchange and poor exercise tolerance evaluated by 6 minute walk test. Severe pulmonary arterial hypertension was also confirmed in three patients. Normal lung volumes does not exclude diagnosis of idiopathic pulmonary fibrosis in patients with concomitant emphysema. The relatively preserved lung volumes may underestimate the severity of idiopathic pulmonary fibrosis and attenuate its effects on lung function parameters.

    2016-01-01

    The British Thoracic Society has published new comprehensive guidelines for the management of pulmonary nodules. These guidelines are significantly different from those previously published, as they use two malignancy prediction calculators to better characterize the risk of malignancy. There are recommendations for a higher nodule size threshold for follow-up (≥5 mm or ≥80 mm(3)) and a reduction of the follow-up period to 1 year for solid pulmonary nodules; both of these will reduce the number of follow-up CT scans. PET-CT plays a crucial role in characterization also, with an ordinal scale being recommended for reporting. Radiologists will be the key in implementing these guidelines, and routine use of volumetric image-analysis software will be required to manage patients with pulmonary nodules correctly.

    To explore the value of ¹⁸F-FDG PET-CT in evaluating bronchial mucosa involvement in patients with saroidosis. A retrospective analysis was conducted among 6 sarcoidosis patients with and 14 patients without bronchial mucosa involvement to collect the data including the standard uptake value (SUVMax/Mean) of ¹⁸F-FDG, serum angiotensin converting enzyme (sACE), and proportion of lymphocytes and CD4⁺/CD8 ⁺ T lymphocyte ratio in bronchoalveolar lavage fluid (BALF). The lung focal SUV(Max/Mean) was higher in patients with bronchial mucosa involvement than those without (7.04 ± 5.83/5.00 ± 4.69 vs 5.68 ± 3.66/3.82 ± 2.39), but such differences were not statistically significant (P=0.565/0.495). The SUV(Max/Mean) of the hilum of the lung and the mediastina lymph nodes were significantly higher in patients with bronchial mucosa involvement (13.28 ± 5.57/10.48 ± 4.43 vs 6.20 ± 1.77/4.52 ± 1.43, P=0.0003/0.0002; 13.84 ± 4.35/9.69 ± 2.74 vs 7.16 ± 2.52/5.28 ± 1.77, P=0.0004/0.0004). The level of sACE and CD4⁺/CD8 ⁺ T lymphocyte ratio in BALF were also significantly higher in patients with bronchial mucosa involvement (60.58 ± 16.3 vs 49.16 ± 13.3 IU/L, P=0.045; 7.30 ± 5.0 vs 2.90 ± 3.1, P=0.026). The proportion of lymphocytes in BALF was comparable between the patients with and without bronchial mucosa involvement (44.10 ± 10.3% vs 35.30 ± 12.5%, P=0.148). For patients with saroidosis, ¹⁸F-FDG PET-CT is useful in evaluating bronchial mucosa involvement, which is one of the key features of active sarcoidosis.

    To review the indications, diagnostic yields and complications of transbronchial biopsy (TBB) in a tertiary hospital in the State of Qatar. A retrospective review of our records revealed 1006 adult flexible fibre optic bronchoscopies (FFB) at Hamad General Hospital, State of Qatar between January 1999 and December 2003. A total of 85 (8.4%) TBB were performed, but complete data were available for 71/85 (83.5%), which were reviewed for indications, diagnostic yields and complications. Adequate samples were obtained in 58/71 TBBs (81.7%), while 13/71 TBBs (18.3%) yielded mucosa. The main indications in 16/71 (22.5%) TBBs for radiographic localized pulmonary diseases were to rule out (TB) in 13 cases, and malignancy in 3 cases. Tuberculosis was verified in 3 (23%) of 13 cases with localized disease. 45 out of 71 (77.5%) TBBs were performed for radiographic diffuse pulmonary disease: 16/55 (29%) for miliary shadows, while 39/55 (70.9%) were carried out for reticular /reticulonodular infiltrates. Histopathology showed granulomatous lesions consistent with TB in 10/16 (62.5%) cases of miliary shadow. In other pattern of diffuse disease, the histopathological diagnosis were obtained in 25/39 (64%) cases. It showed non-specific pulmonary fibrosis in 13 cases, sarcoidosis in 4 cases, connective tissue disease associated interstitial fibrosis in 4 cases, bronchiolitis obliterans organizing pneumonia (BOOP) in one case, eosinophilic pneumonia in one case, amiodarone toxicity in one case and lymphangitis carcinomatosis in one case. The main complications were minor bleeding <50 cc in 17 cases (23.9%) pneumothorax in 7 cases (9.8%) and one case has sepsis. Our experience substantiates previous reports of the value and safety of transbronchial biopsy in rapid diagnosis smear-negative miliary TB. In diffuse lung diseases of a non-infectious nature, other than sarcoidosis, lymphangitis carcinomatosis and few other conditions, a pathological diagnosis are much less likely to be

    Pulmonary arterial dissection is an uncommon but usually a deadly complication of chronic pulmonary hypertension. A 26-year-old female patient was admitted to our clinics with sudden dyspnea and chest discomfort one hour after giving birth to twins by vaginal delivery. An echocardiography was performed with a pre-diagnosis of pulmonary embolism. However, echocardiographic examination revealed a dilated main pulmonary artery and a dissection flap extending from main pulmonary artery to left pulmonary artery. In summary, in this report, we described a very rare case of pulmonary artery dissection in a pregnant patient with a previously un-diagnosed patent ductus arteriosus without an obvious rise in pulmonary artery pressure and reviewed the relevant literature.

    Carbon monoxide poisoning, a public health problem of considerable significance, is a relatively frequent event today, resulting in thousands of hospitalizations annually. A 70-year-old lady was seen in the emergency department with a provisional diagnosis of carbon monoxide poisoning. The previous night, she slept in a tightly closed room heated with coal ember. She was found unconscious in the morning with poor ventilation. She had a rare presentation of popliteal vein thrombosis, pulmonary emboli, and possible tissue necrosis with carbon monoxide poisoning. Oxygen treatment with low-molecular-weight heparin (nadroparine) and warfarin therapy resulted in an improvement in both popliteal and pulmonary circulations. In conclusion, the presence of pulmonary emboli should be sought in patients with carbon monoxide poisoning.

    Computed tomography (CT) of the lung in normal subjects and patients with congestive heart failure was performed in the supine position with deep inspiration to obtain pulmonary CT values and images. The mean CT value in normal subjects was higher in the posterior than anterior lung field, presumably because blood vessels were more dilated in the former than the latter due to the effects of gravity. The mean pulmonary CT value in patients with congestive heart failure was significantly increased possibly due to an increase in blood flow per unit lung volume arising from either pulmonary congestion or pulmonary interstitial and alveolar edema. The mean pulmonary CT value increased parallel to the severity of pulmonary congestion, interstitial or alveolar edema and was well correlated with the pulmonary arterial wedge pressure, indicating that such a correlation was a valuable tool in assessing therapeutic effects. The results of the present study indicatethat pulmonary CT is useful for the noninvasive estimation of intrapulmonary water content and its distribution, thereby providing an effective diagnostic clue to various conditions in congestive heart failure.

    PET/CT is a high sensitive, but low-specific method visualizing all the metabolic active processes. Fluoro-deoxyglucose (18F-FDG) uptake is high in tumors, as well as in infections, inflammations, granulomatous processes, post-radiotherapy alterations and in activated organs and tissues like brown fat, adrenals, thyroid, thymus, or bone marrow. This uptake can represent differential diagnostic problem. The clinical case is a young patient with invasive ductal and lobular breast carcinoma, after sectorial resection, without lymph node dissection. The chemotherapy was stopped after 3 courses due to thrombosis of vena cephalica. The local clinical status raises suspicion of recurrence, as the ultrasound. PET/CT was not conclusive about mediastinal lymph node involvement. The histology proves sarcoidosis, which frequently demonstrates symmetric 18F-FDG avid mediastinal and hilar lymph nodes. However the biopsy is mandatory, because of the low specificity of PET/CT for discrimination of this systemic disorder from tumor involvement. Keywords: PET/CT. Differential Diagnostic Problems

    Full Text Available In chronic thromboembolic pulmonary hypertension, stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension. Chronic thromboembolic pulmonary hypertension can be cured surgically by pulmonary endarterectomy; however, patients deemed unsuitable for pulmonary endarterectomy due to lesion, advanced age, or comorbidities have a poor prognosis and limited treatment options. Recently, advances have been made in balloon pulmonary angioplasty for these patients, and this review highlights this recent progress.

    The aim of the study was to assess the clinical features and treatment responses in Iranian patients with sarcoid uveitis. A retrospective review of patients diagnosed with sarcoid uveitis from 1996 to 2010 was performed in a referral clinic in Tehran, Iran. Demographic and clinical features of patients, treatment modalities and therapeutic responses, and outcomes were recorded. Sixty-six eyes from 36 patients were studied. Twenty cases had biopsy-proven sarcoidosis. Mean duration of follow-up was 44.7 ± 45 months (range 3-175). Thirty-six eyes (54.5 %) had intermediate uveitis, 25 (37.9 %) panuveitis, and 5 (7.6 %) anterior uveitis. Twenty patients (55.5 %) responded to both systemic and/or topical corticosteroids, and 16 (44.4 %) required immunomodulatory drugs for control of uveitis. All of the patients finally responded to treatment in the form of inflammation reduction and/or vision improvement. The average time interval before initial clinical response following treatment was 3.2 ± 3 months (range 1-72). This study disclosed a higher predominance of females and intermediate form of uveitis in Iranian patients with sarcoid uveitis. Use of immunomodulatory drugs combined with corticosteroids resulted in good visual outcome and control of uveitis with a possible fewer corticosteroid side effects.

  6. Suspected Pulmonary Embolism during Hickman Catheterization in a Child: What Else Should Be Considered besides Pulmonary Embolism?

    Full Text Available A 16-month-old girl with acute lymphoblastic leukemia expired during Hickman catheter insertion. She had undergone chemoport insertion of the left subclavian vein six months earlier and received five cycles of chemotherapy. Due to malfunction of the chemoport and the consideration of hematopoietic stem cell transplantation, insertion of a Hickmann catheter on the right side and removal of the malfunctioning chemoport were planned under general anesthesia. The surgery was uneventful during catheter insertion, but the patient experienced the sudden onset of pulseless electrical activity just after saline was flushed through the newly inserted catheter. Cardiopulmonary resuscitation was commenced aggressively, but the patient was refractory. Migration of a thrombus generated by the previous central catheter to the pulmonary circulation was suspected, resulting in a pulmonary embolism.

  7. TINF2 Gene Mutation in a Patient with Pulmonary Fibrosis

    Full Text Available Pulmonary fibrosis is a frequent manifestation of telomere syndromes. Telomere gene mutations are found in up to 25% and 3% of patients with familial disease and sporadic disease, respectively. The telomere gene TINF2 encodes an eponymous protein that is part of the shelterin complex, a complex involved in telomere protection and maintenance. A TINF2 gene mutation was recently reported in a family with pulmonary fibrosis. We identified a heterozygous Ser245Tyr mutation in the TINF2 gene of previously healthy female patient that presented with progressive cough due to pulmonary fibrosis as well as panhypogammaglobulinemia at age 52. Retrospective multidisciplinary evaluation classified her as a case of possible idiopathic pulmonary fibrosis. Telomere length-measurement indicated normal telomere length in the peripheral blood compartment. This is the first report of a TINF2 mutation in a patient with sporadic pulmonary fibrosis, which represents another association between TINF2 mutations and this disease. Furthermore, this case underlines the importance of telomere dysfunction and not telomere length alone in telomere syndromes and draws attention to hypogammaglobulinemia as a manifestation of telomere syndromes.

    Objective: This study was designed to investigate the sensitivity and specificity of magnetic resonance pulmonary perfusion imaging (MRPP) in diagnosing pulmonary embolism (PE) compared with enhanced magnetic resonance pulmonary angiography (MRPA) and pulmonary radionuclide perfusion imaging. Methods: Fourteen patients were definitely diagnosed as PE, whose ages were from 19 to 71 years old and mean 45.5 ± 19.8 years old. All patients under went MRPA and MRPP and 3 patients were examined again after thrombolytic treatment. Five patients underwent pulmonary radionuclide perfusion imaging. Setting ROI in top, middle, bottom of lung area and abnormal area respectively, we detected signal intensity and time-signal curve to obtain the transformation rate of signal (TROS) during perfusion peak value. Results: In 14 pulmonary embolism patients, MRPA found 62 branches of pulmonary artery obstruction. Fifty-five abnormal pulmonary perfusion zones were found by MRPP, and the above results were very alike. The coincidence was 88.71%. In 14 cases, MRPP could show 25 subsegments lesion below segments. In 5 patients who had both results Of MRPP and ECT at the same time. MRPP shows 33 perfusion defect zones and 37 segments were found by ECT, the sensitivity was 89.19%. After thrombolytic treatment, both the status of the affected pulmonary artery improved markedly and perfusion defect zones reduced obviously in 3 cases by MRPP and MRPA. TROS in normal perfusion zones perfusion defect zones and low perfusion zones had significant difference (t=22.882, P<0.01). Conclusion: Contrast enhanced MR pulmonary perfusion can show both perfusion defect zones and low perfusion zones in pulmonary embolism. Time-signal curve can show the period of maximum no perfusion zones in pulmonary artery embolism zones. And the amplitude of fluctuation is small with miminum TROS. MRPP has significant values especially in showing pulmonary artery embolism in segments and subsegments. Using both MRPP and

    Objective: To assess the value of ventilation-perfusion imaging in the diagnosis of pulmonary embolism (PE). Methods: Thirty consecutive patients with clinically suspected pulmonary embolism were studied, male: female 15:15, mean age was (36.2 +- 13.9) years. The chest radiograms were obtained in all 30 patients. All patients underwent radionuclide ventilation-perfusion imaging and pulmonary angiography. Results: Of the 30 patients, 22 with lobe, multiple segment or multi-subsegment perfusion defects and normal or nearly normal ventilation images were reported as PE. 20 of them were confirmed to be with PE by pulmonary angiography, 2 patients were not confirmed. Eight of 30 patients with multiple perfusion defects, ventilative abnormalities were reported as non-PE and the diagnoses were confirmed by pulmonary angiography. The sensitivity, specificity and accuracy of diagnosis of PE by ventilation-perfusion imaging was 100%, 80.0% and 93.3% respectively. Conclusions: (1) Ventilation-perfusion imaging is one of the most valuable methods in the diagnosis of PE. (2) The results suggest that pulmonary embolism can be diagnosed non-invasively in most patients on the basis of clinical manifestation, chest radiograms and ventilation-perfusion imaging findings. (3) Pulmonary angiography is required while clinical manifestation and ventilation-perfusion imaging findings are discordant with each other

    OBJECTIVE: The purpose of this study was to retrospectively compare the diagnostic adequacy of lung scintigraphy with that of pulmonary CT angiography (CTA) in the care of pregnant patients with suspected pulmonary embolism. MATERIALS AND METHODS: Patient characteristics, radiology report content, additional imaging performed, final diagnosis, and diagnostic adequacy were recorded for pregnant patients consecutively referred for lung scintigraphy or pulmonary CTA according to physician preference. Measurements of pulmonary arterial enhancement were performed on all pulmonary CTA images of pregnant patients. Lung scintigraphy and pulmonary CTA studies deemed inadequate for diagnosis at the time of image acquisition were further assessed, and the cause of diagnostic inadequacy was determined. The relative contribution of the inferior vena cava to the right side of the heart was measured on nondiagnostic CTA images and compared with that on CTA images of age-matched nonpregnant women, who were the controls. RESULTS: Twenty-eight pulmonary CTA examinations were performed on 25 pregnant patients, and 25 lung scintigraphic studies were performed on 25 pregnant patients. Lung scintigraphy was more frequently adequate for diagnosis than was pulmonary CTA (4% vs 35.7%) (p = 0.0058). Pulmonary CTA had a higher diagnostic inadequacy rate among pregnant than nonpregnant women (35.7% vs 2.1%) (p < 0.001). Transient interruption of contrast material by unopacified blood from the inferior vena cava was identified in eight of 10 nondiagnostic pulmonary CTA studies. CONCLUSION: We found that lung scintigraphy was more reliable than pulmonary CTA in pregnant patients. Transient interruption of contrast material by unopacified blood from the inferior vena cava is a common finding at pulmonary CTA of pregnant patients.

    Since populations evolve, measurement protocols and equipment improve and analysis techniques progress, there is an ongoing need to reassess reference data for pulmonary function tests. Furthermore, reference values for total lung capacity and carbon monoxide diffusion capacity are scarcely available in children. We aimed to provide updated reference equations for most commonly used pulmonary function indices in Caucasian children. In the 'Utrecht Pulmonary Function Reference Data Study' we collected data in Caucasian children aged 2-18 years. We analyzed them using the 'Generalized Additive Models for Location Scale and Shape' (GAMLSS) statistical method. Measurements of interrupter resistance (R(int)) (n = 877), spirometry (n = 1042), body plethysmography (n = 723) and carbon monoxide diffusion/helium dilution (n = 543) were obtained in healthy children. Height (or the natural logarithm of height) and age (or the natural logarithm of age) were both significantly related to most outcome measures. Also sex was a significant determinant, except for RV, RV/TLC, FRC(pleth), Raw(0,5), Raw(tot), R(int) and FEF values. The application of previously published reference equations on the study population resulted in misinterpretation of pulmonary function. These new paediatric reference equations provide accurate estimates of the range of normality for most commonly used pulmonary function indices, resulting in less underdiagnosis and overdiagnosis of pulmonary diseases.

    Pulmonary arterial hypertension (PAH) occurs more frequently in women with mutations in bone morphogenetic protein receptor type 2 (BMPR2) and dysfunctional BMPR2 signalling underpinning heritable PAH. We have previously shown that serotonin can uncover a pulmonary hypertensive phenotype in BMPR2(+/-) mice and that oestrogen can increase serotinergic signalling in human pulmonary arterial smooth muscle cells (hPASMCs). Hence, here we wished to characterize the expression of oestrogen receptors (ERs) in male and female human pulmonary arteries and have examined the influence of oestrogen and serotonin on BMPR2 and ERα expression. By immunohistochemistry, we showed that ERα, ERβ, and G-protein-coupled receptors are expressed in human pulmonary arteries localizing mainly to the smooth muscle layer which also expresses the serotonin transporter (SERT). Protein expression of ERα protein was higher in female PAH patient hPASMCs compared with male and serotonin also increased the expression of ERα. 17β-estradiol induced proliferation of hPASMCs via ERα activation and this engaged mitogen-activated protein kinase and Akt signalling. Female mice over-expressing SERT (SERT(+) mice) develop PH and the ERα antagonist MPP attenuated the development of PH in normoxic and hypoxic female SERT(+) mice. The therapeutic effects of MPP were accompanied by increased expression of BMPR2 in mouse lung. ERα is highly expressed in female hPASMCs from PAH patients and mediates oestrogen-induced proliferation of hPASMCs via mitogen-activated protein kinase and Akt signalling. Serotonin can increase ERα expression in hPASMCs and antagonism of ERα reverses serotonin-dependent PH in the mouse and increases BMPR2 expression.

    Within clinical respiratory functional explorations, a pulmonary clearance study was performed on two groups of patients: 20 normal individuals for the former, 18 for the latter, most of them suffering from various diseases (sarcoidosis, tuberculosis, chronic bronchitis and pneumoconiosis). Each group included smokers and non-smokers. 198 Au aerosols were administered to the former group, and 51 Cr-labelled polystyrene spherical particles to the latter. Low-level whole-body γ-spectrometry was carried out for several weeks or several months. The retention curves are exponential, and the calculated half-lives were compared to several data: age, sex, profession, cigarette smoking rate, spirometric explorations, etiology. The normal biological half-life is about 68 days; it is significatively increased by smoking, it is also increased in the pathological conditions considered, except sarcoidosis [fr

    Pulmonary hypertension is a significant cause of morbidity and mortality in infants. Historically, there has been significant study of the signaling pathways involved in vascular smooth muscle contraction in PASMC from fetal sheep. While sheep make an excellent model of term pulmonary hypertension, they are very expensive and lack the advantage of genetic manipulation found in mice. Conversely, the inability to isolate PASMC from mice was a significant limitation of that system. Here we described the isolation of primary cultures of mouse PASMC from P7, P14, and P21 mice using a variation of the previously described technique of Marshall et al. that was previously used to isolate rat PASMC. These murine PASMC represent a novel tool for the study of signaling pathways in the neonatal period. Briefly, a slurry of 0.5% (w/v) agarose + 0.5% iron particles in M199 media is infused into the pulmonary vascular bed via the right ventricle (RV). The iron particles are 0.2 μM in diameter and cannot pass through the pulmonary capillary bed. Thus, the iron lodges in the small pulmonary arteries (PA). The lungs are inflated with agarose, removed and dissociated. The iron-containing vessels are pulled down with a magnet. After collagenase (80 U/ml) treatment and further dissociation, the vessels are put into a tissue culture dish in M199 media containing 20% fetal bovine serum (FBS), and antibiotics (M199 complete media) to allow cell migration onto the culture dish. This initial plate of cells is a 50-50 mixture of fibroblasts and PASMC. Thus, the pull down procedure is repeated multiple times to achieve a more pure PASMC population and remove any residual iron. Smooth muscle cell identity is confirmed by immunostaining for smooth muscle myosin and desmin.

    Conclusions: pulmonary hemorrhage is more prevalent in premature newborns, and is associated with intubation in the delivery room and previous use of blood components, leading to high mortality and worse clinical evolution.

  2. Delayed Diagnosis in an Elderly Schizophrenic Patient with Catatonic State and Pulmonary Embolism

    Full Text Available Catatonia is a syndrome with any two of five core features: stupor/motoric immobility/catalepsy/waxy flexibility, excitement, negativism/mutism, posturing, and echolalia/echopraxia. We describe a case of delayed diagnosis of pulmonary embolism with an atypical presentation in an elderly schizophrenia male patient, which led to a life-threatening brain infarction. A 75-year-old male was hospitalized in a psychiatric ward because of stupor, poor intake and mutism under a diagnosis of recurrent catatonia. His inability to express his suffering, dehydration, exacerbation of chronic obstructive pulmonary disease, and upper gastrointestinal bleeding, however, made an accurate diagnosis difficult. Finally, the high D-dimer level and further chest computed tomography confirmed pulmonary embolism in the trunk of the bilateral main pulmonary arteries. The brain computed tomography also confirmed brain infarcts. He was transferred to the cardiac intensive care unit and was eventually rescued from near death due to pulmonary embolism and brain infarction. A careful differential diagnosis for pulmonary embolism-induced delirium and catatonic state is important in the treatment of patients with a previous diagnosis of catatonic schizophrenia.

  3. Self-management programmes for people living with chronic obstructive pulmonary disease: a call for a reconceptualisation.

    To synthesise findings from previously published studies on the effectiveness of self-management programmes for people with chronic obstructive pulmonary disease. Self-management is a widely valued concept to address contemporary issues of chronic health problems. Yet, findings of self-management programmes for people with chronic obstructive pulmonary disease are indecisive. Literature review of (1) previously published systematic reviews and (2) an integrative literature review. Synthesis of findings from previously published systematic reviews (n = 4) of the effectiveness of self-management programmes for people with chronic obstructive pulmonary disease and an integrated review that was performed on papers published between January 2007-June 2012 (n = 9). Findings demonstrate that there are few studies on the effectiveness of self-management programmes on people with chronic obstructive pulmonary disease despite more than a decade of research activities. Outcomes of the studies reveal some increase in health-related quality of life and reduction in use of healthcare resources. The methodological approaches vary, and the sample size is primarily small. Families are not acknowledged. Features of patient-centredness exist in self-management programmes, particularly in the more recent articles. The effectiveness of self-management programmes for people with chronic obstructive pulmonary disease remains indecisive. A reconceptualisation of self-management programmes is called for with attention to a family-centred, holistic and relational care focusing on living with and minimising the handicapping consequences of the health problems in their entirety. © 2013 Blackwell Publishing Ltd.

    Pulmonary hypertension is frequently observed in advanced idiopathic pulmonary fibrosis (IPF) and is associated with poor prognosis. Cardiopulmonary exercise testing (CPET) can be used to detect less advanced pulmonary vascular impairment, and therefore may be of prognostic use. We studied the

  5. The influence of weather and environment on pulmonary embolism: pollutants and fossil fuels.

    Previous publications have highlighted seasonal variations in the incidence of thrombosis and pulmonary embolism, and that weather patterns can influence these. While medical risk factors for pulmonary thrombo-embolism such as age, obesity, hypercoagulable states, cancer, previous thrombo-embolism, immobility, limb paralysis, surgery, major illness, trauma, hypotension, tachypnoea and right ventricular hypokinesis are not directly implicated regarding environmental factors such as weather, they could be influenced indirectly by these. This would be especially relevant in polluted areas that are associated with a higher pulmonary embolism risk. Routine nuclear medicine lung ventilation/perfusion studies (V/Q scans) of 2071 adult patients referred to the nuclear medicine department of the Royal Surrey County Hospital in Guildford, UK, between January 1998 and October 2002 were reviewed and 316 of these patients were classified as positive for pulmonary embolism with high probability scan on PIOPED criteria. The occurrence of positive scans was compared to environmental factors such as temperature, humidity, vapour pressure, air pressure and rainfall. Multiple linear regression was used to establish the significance of these relations. The incidence of pulmonary embolism was positively related to vapour pressure and rainfall. The most significant relation was to vapour pressure (p=0.010) while rainfall was less significant (p=0.017). There was no significant relation between pulmonary embolism and air pressure, humidity or temperature. It is postulated that rainfall and water vapour may be contributary factors in thrombosis and pulmonary embolism by way of pollutants that are carried as condensation nuclei in micro-droplets of water. In particular, fossil fuel pollutants are implicated as these condensation nuclei. Pollutants may be inhaled by populations exposed to windborne vapour droplets in cities or airports. Polluted vapour droplets may be absorbed by the lung

  6. Pulmonary endarterectomy in the management of chronic thromboembolic pulmonary hypertension

    Directory of Open Access Journals (Sweden)

    David Jenkins

    2017-03-01

    Full Text Available Chronic thromboembolic pulmonary hypertension (CTEPH is a type of pulmonary hypertension, resulting from fibrotic transformation of pulmonary artery clots causing chronic obstruction in macroscopic pulmonary arteries and associated vascular remodelling in the microvasculature. Pulmonary endarterectomy (PEA offers the best chance of symptomatic and prognostic improvement in eligible patients; in expert centres, it has excellent results. Current in-hospital mortality rates are 90% at 1 year and >70% at 10 years. However, PEA, is a complex procedure and relies on a multidisciplinary CTEPH team led by an experienced surgeon to decide on an individual's operability, which is determined primarily by lesion location and the haemodynamic parameters. Therefore, treatment of patients with CTEPH depends largely on subjective judgements of eligibility for surgery by the CTEPH team. Other controversies discussed in this article include eligibility for PEA versus balloon pulmonary angioplasty, the new treatment algorithm in the European Society of Cardiology/European Respiratory Society guidelines and the definition of an “expert centre” for the management of this condition.

  7. Does exercise pulmonary hypertension exist?

    Science.gov (United States)

    Lau, Edmund M; Chemla, Denis; Whyte, Kenneth; Kovacs, Gabor; Olschewski, Horst; Herve, Philippe

    2016-09-01

    The exercise definition of pulmonary hypertension using a mean pulmonary artery pressure threshold of greater than 30 mmHg was abandoned following the 4th World Pulmonary Hypertension Symposium in 2008, as this definition was not supported by evidence and healthy individuals frequently exceed this threshold. Meanwhile, the clinical value of exercise pulmonary hemodynamic testing has also been questioned. Recent data support the notion that an abnormal pulmonary hemodynamic response during exercise (or exercise pulmonary hypertension) is associated with symptoms and exercise limitation. Pathophysiologic mechanisms accounting for the development of exercise pulmonary hypertension include increased vascular resistance, excessive elevation in left atrial pressure and/or increased volume of trapped air during exercise, resulting in a steep rise in pulmonary artery pressure relative to cardiac output. Recent evidence suggests that exercise pulmonary hypertension may be defined by a mean pulmonary artery pressure surpassing 30 mmHg together with a simultaneous total pulmonary resistance exceeding 3 WU. Exercise pulmonary hypertension is a clinically relevant entity and an improved definition has been suggested based on new evidence. Exercise pulmonary hemodynamics may help unmask early or latent disease, particularly in populations that are at high risk for the development of pulmonary hypertension.

  8. Definition and classification of pulmonary hypertension.

    Science.gov (United States)

    Humbert, Marc; Montani, David; Evgenov, Oleg V; Simonneau, Gérald

    2013-01-01

    Pulmonary hypertension is defined as an increase of mean pulmonary arterial pressure ≥25 mmHg at rest as assessed by right heart catheterization. According to different combinations of values of pulmonary wedge pressure, pulmonary vascular resistance and cardiac output, a hemodynamic classification of pulmonary hypertension has been proposed. Of major importance is the pulmonary wedge pressure which allows to distinguish pre-capillary (pulmonary wedge pressure ≤15 mmHg) and post-capillary (pulmonary wedge pressure >15 mmHg) pulmonary hypertension. Pre-capillary pulmonary hypertension includes the clinical groups 1 (pulmonary arterial hypertension), 3 (pulmonary hypertension due to lung diseases and/or hypoxia), 4 (chronic thrombo-embolic pulmonary hypertension) and 5 (pulmonary hypertension with unclear and/or multifactorial mechanisms). Post-capillary pulmonary hypertension corresponds to the clinical group 2 (pulmonary hypertension due to left heart diseases).

  9. Pulmonary vascular imaging

    1987-01-01

    A wide range of pulmonary vascular imaging techniques are available for the diagnostic evaluation of patients with suspected pulmonary vascular disease. The characteristics of any ideal technique would include high sensitivity and specificity, safety, simplicity, and sequential applicability. To date, no single technique meets these ideal characteristics. Conventional pulmonary angiography remains the gold standard for the diagnosis of acute thromboembolic disease despite the introduction of newer techniques such as digital subtraction angiography and magnetic resonance imaging. Improved noninvasive lower extremity venous testing methods, particularly impedance plethysmography, and ventilation-perfusion scanning can play significant roles in the noninvasive diagnosis of acute pulmonary emboli when properly applied. Ventilation-perfusion scanning may also be useful as a screening test to differentiate possible primary pulmonary hypertension from chronic thromboembolic pulmonary hypertension. And, finally, angioscopy may be a useful adjunctive technique to detect chronic thromboembolic disease and determine operability. Optimal clinical decision-making, however, will continue to require the proper interpretation of adjunctive information obtained from the less-invasive techniques, applied with an understanding of the natural history of the various forms of pulmonary vascular disease and with a knowledge of the capabilities and shortcomings of the individual techniques

  10. Effect of carbon dioxide inhalation on pulmonary hypertension induced by increased blood flow and hypoxia

    Directory of Open Access Journals (Sweden)

    I-Chun Chuang

    2011-08-01

    Full Text Available There is now increasing evidence from the experimental and clinical setting that therapeutic hypercapnia from intentionally inspired carbon dioxide (CO2 or lower tidal volume might be a beneficial adjunct to the strategies of mechanical ventilation in critical illness. Although previous reports indicate that CO2 exerts a beneficial effect in the lungs, the pulmonary vascular response to hypercapnia under various conditions remains to be clarified. The purpose of the present study is to characterize the pulmonary vascular response to CO2 under the different conditions of pulmonary hypertension secondary to increased pulmonary blood flow and secondary to hypoxic pulmonary vasoconstriction. Isolated rat lung (n = 32 was used to study (1 the vasoactive action of 5% CO2 in either N2 (hypoxic-hypercapnia or air (normoxic-hypercapnia at different pulmonary arterial pressure levels induced by graded speed of perfusion flow and (2 the role of nitric oxide (NO in mediating the pulmonary vascular response to hypercapnia, hypoxia, and flow-associated pulmonary hypertension. The results indicated that inhaled CO2 reversed pulmonary hypertension induced by hypoxia but not by flow alteration. Endogenous NO attenuates hypoxic pulmonary vasoconstriction but does not augment the CO2-induced vasodilatation. Acute change in blood flow does not alter the endogenous NO production.

  11. Familial Interstitial Pulmonary Fibrosis: A Large Family with Atypical Clinical Features

    2010-01-01

    Full Text Available A large kindred of familial pulmonary fibrosis is reported. Six members from the first two generations of this particular kindred were described more than 40 years previously; six more individuals from the third and fourth generations have also been evaluated. The proband, now 23 years of age, has mild disease; the other 11 documented affected family members all died from their disease at an average age of 37 years (range 25 to 50 years. The pathology was that of usual interstitial pneumonia, as is typical in idiopathic pulmonary fibrosis. However, the initial radiographic pattern in many of these individuals was upper lobe and nodular and, along with the young age, was atypical for idiopathic pulmonary fibrosis. Several genetic abnormalities have been associated with familial pulmonary fibrosis. The present study examined the genes coding for surfactant protein-C, ATP-binding cassette protein A3 and telomerase, and found no abnormalities.

  12. Bilateral pulmonary infiltrates in association with disseminated actinomycosis.

    1994-07-01

    The most common infectious cause of bilateral upper-lobe pulmonary disease is tuberculosis. However, we recently encountered a patient with bilateral apical infiltrates and multiple soft-tissue abscesses caused by Actinomyces odontolyticus. Other findings included fever, weight loss, and leukocytosis, and the patient's only known source of immunosuppression was a long history of alcoholism. There was no history of diabetes, steroid use, or other chronic underlying disease. The diagnosis was made by culture of drainage fluid from one abscess. Therapy with intravenous penicillin G led to rapid clinical improvement and reduction in the infiltrates. To our knowledge, the presentation of pulmonary infection, with bilateral apical infiltrates due to A. odontolyticus has not been previously reported in the medical literature.

    Pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD) is a complex disease that presents with a broad spectrum of morphological and haemodynamic findings of varying severity. Recently, the aspect of paediatric pulmonary hypertensive vascular disease (PPHVD) has been introduced to expand the understanding of the full spectrum of pulmonary hypertension and increased pulmonary vascular resistance. Evaluation and treatment of PAH-CHD/PPHVD-CHD can be divided into in different topics. First, defining criteria for operability and initiation of advanced therapies preoperatively and postoperatively is an unresolved issue. Second, management of Eisenmenger syndrome is still an important question, with recent evidence on the severity of the disease and a more rapidly progressive course than previously described. Third, the Fontan circulation with no subpulmonary ventricle requires a distinct discussion, definition and classification since even a mild rise in pulmonary vascular resistance may lead to the so-called failing Fontan situation. Patients with CHD and single-ventricle physiology (Fontan/total cavopulmonary anastomosis) require a particularly stepwise and individualised approach. This consensus statement is on the current evidence for the most accurate evaluation and treatment of increased pulmonary artery pressure and resistance, as well as ventricular dysfunction, in children with congenital heart defects, and provides according practical recommendations. To optimise preoperative and postoperative management in patients with PAH-CHD, diagnostic and treatment algorithms are provided. Published by the BMJ Publishing Group Limited.

    Activation of both the sympathetic nervous system and the renin-angiotensin-aldosterone system is closely associated with pulmonary arterial hypertension. We hypothesized that renal denervation decreases renin-angiotensin-aldosterone activity and inhibits the progression of pulmonary arterial hypertension. Twenty-two beagles were randomized into 3 groups. The dogs' pulmonary dynamics were measured before and 8 weeks after injection of 0.1mL/kg dimethylformamide (control dogs) or 2mg/kg dehydromonocrotaline (pulmonary arterial hypertension and pulmonary arterial hypertension + renal denervation dogs). Eight weeks after injection, neurohormone levels and pulmonary tissue morphology were measured. Levels of plasma angiotensin II and endothelin-1 were significantly increased after 8 weeks in the pulmonary arterial hypertension dogs and were higher in the lung tissues of these dogs than in those of the control and renal denervation dogs (mean [standard deviation] angiotensin II: 65 [9.8] vs 38 [6.7], 46 [8.1]; endothelin-1: 96 [10.3] vs 54 [6.2], 67 [9.4]; P < .01). Dehydromonocrotaline increased the mean pulmonary arterial pressure (16 [3.4] mmHg vs 33 [7.3] mmHg; P < .01), and renal denervation prevented this increase. Pulmonary smooth muscle cell proliferation was higher in the pulmonary arterial hypertension dogs than in the control and pulmonary arterial hypertension + renal denervation dogs. Renal denervation attenuates pulmonary vascular remodeling and decreases pulmonary arterial pressure in experimental pulmonary arterial hypertension. The effect of renal denervation may contribute to decreased neurohormone levels. Copyright © 2014 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

  15. A study on the pulmonary mean transit time and the pulmonary blood volume by RI-cardiogram

    The pulmonary mean transit time and the pulmonary blood volume in cases of cardio-pulmonary disease were measured using Giuntini's method which is considered the most appropriate among radiocardiographic methods. The errors in this method were confirmed to be almost negligible. The results obtained were as follows: 1) The pulmonary mean transit time was related to the systemic mean transit time and markedly prolonged in left heart failure. On the other hand, it was markedly shortened in some cases of chronic pulmonary disease, particularly pulmonary emphysema. 2) The pulmonary blood volume tended to increase in left heart disorders and mitral valve disease and tended to decrease in the chronic pulmonary disease. The decrease was conspicuous particularly in some cases of pulmonary emphysema. 3) A structural change of the pulmonary vascular system in the chronic pulmonary disease appeared to bring about shortening of the pulmonary mean transit time and a decrease in the pulmonary blood volume. The pathophysiology of cardio-pulmonary disease can be more clarified by the RI-cardiogram used in this study, in which the pulmonary mean transit time and the pulmonary blood volume are used as the indicator.

    Objective: To compare the principal HRCT features of peripheral pulmonary squamous cell carcinoma and pulmonary adenocarcinoma and to explore their pathological mechanism, in order to improve the recognition of the CT signs of peripheral pulmonary carcinoma. Methods: The principal HRCT signs of thirty-five cases with pathologically proved peripheral pulmonary squamous cell carcinoma and forty cases with pathologically proved peripheral pulmonary adenocarcinoma were analyzed retrospectively to explore the relationship between CT features and pathological findings. Results: The main features of peripheral pulmonary squamous cell carcinoma included larger masses, clear boundary, superficial sublobes and intra-tumor necrosis. While peripheral pulmonary adenocarcinoma mostly demonstrated as smaller nodules, deep sublobes, spiculations, spiculate protuberance, pleural indentation, vessel converging signs, and vacuole signs. The different of these above findings of peripheral pulmonary squamous cell carcinoma and adenocarcinoma were significant (P<0.05). Peripheral pulmonary squamous cell carcinoma may depict bronchial casts and polygonal nodules; and peripheral pulmonary adenocarcinoma may demonstrate ground glass-like nodules. Conclusion: The difference of the CT findings between peripheral pulmonary squamous cell carcinoma and peripheral adenocarcinoma is based on their different histological features and biological behaviors. It is possible to differentiate them before operation in combination with clinical information. (authors)

    We investigated the correlation between CT and pulmonary function test results in five normal controls and ten patients with severe pulmonary emphysema. We used mean lung attenuation values (MLAV) and ΔEMP as the index of emphysematous change in CT. ΔEMP was defined as the ratio of the area (-960 Hounsfield Units ∼ -1024 HU) to the area (-774 HU ∼ -1024 HU). MLAV and ΔEMP were measured from histograms of the CT review. Mean MLAV in pulmonary emphysema was -947.1 ± 9.3 HU, and that in normal controls was -906.6 ± 23.6 HU. Mean ΔEMP in pulmonary emphysema was 50.0 ± 9.9 %, and that in normal controls was 18.8 ± 13.0 %. The data in pulmonary emphysema cases differed significantly from those in normal controls. Furthermore MLAV and ΔEMP had good correlation to VC, %VC, FEV 1 , FEV 1 /FVC, RV/TLC, %V 25 and Raw. CT is an easier examination than pulmonary function test for patients, and can show the extent and the distribution of emphysematous area. In this study it is suggested that CT is a useful examination in severe pulmonary emphysema. (author)

    1982-01-01

    In 4 sheeps, base lines of hemodynamics and lymph dynamics were observed for 2 hours, and then 1,000 rad of 60 Co was irradiated to the inferior lobes of the lung. Pulmonary hemodynamics and lymph dynamics were continuously observed, and water and protein permeability of the irradiated pulmonary vessels was evaluated. In 4 control sheeps, no change in pulmonary hemodynamics and lymph dynamics was noted. In the irradiated group, there was no remarkable change in pulmonary hemodynamics for 6 to 8 hours after 60 Co irradiation. Pulmonary lymph flow began to increase 2 hours after irradiation to about 1.7 times the base line level after 4 hours. The increase in pulmonary lymph flow was accompanied by decrease in plasma protein concentration and increase in protein concentration of the lung lymph, resulting in an apparent increase in the ratio of lymph/plasma protein concentration. Water and protein leak from the pulmonary vessels increased. A photomicroscopic observation revealed dilatation of the lymphatic vessels in the lung interstice and a mild pulmonary interstitial edema. Vascular damage, especially due to increased water and protein permeability of the lung capillary vessels, occurred immediately after 60 Co irradiation. (Ueda, J.)
