Impaired aortic elastic properties in patients with systemic sarcoidosis

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 2 2008
I. Moyssakis
Abstract Background, Systemic sarcoidosis (Sar) is a granulomatous disorder involving multiple organs. Widespread vascular involvement and microangiopathy are common in patients with Sar. In addition, subclinical cardiac involvement is increasingly recognized in patients with Sar. However, data on the effect of Sar on the elastic properties of the arteries and myocardial performance are limited. In this study we looked for differences in aortic distensibility (AoD) which is an index of aortic elasticity, and myocardial performance of the ventricles, between patients with Sar and healthy subjects. In addition, we examined potential associations between AoD and clinical, respiratory and echocardiographic findings in patients with Sar. Materials and methods, A total of 83 consecutive patients (26 male/57 female, mean age 51·1 ± 13·3 years) with Sar, without cardiac symptoms, were included. All patients underwent echocardiographic and respiratory evaluation including lung function tests. Additionally, 83 age- and sex-matched healthy subjects served as controls. AoD was determined non-invasively by ultrasonography. Results, AoD was lower in the Sar compared to the control group (2·29 ± 0·26 vs. 2·45 ± 0·20 ·10,6 cm2· dyn,1, P < 0·01), while left ventricular mass (LVM) was higher in the Sar group (221·3 ± 50·2 vs. 195·6 ± 31·3 g, P = 0·007). Furthermore, myocardial performance of both ventricles was impaired in the Sar group. Multivariate linear regression analysis in the total sample population demonstrated a significant and independent inverse relationship between AoD and the presence of Sar (P < 0·001). The same analysis in the Sar patients showed that AoD was associated significantly and independently with the stage of Sar, age, systolic blood pressure, LVM and myocardial performance of both ventricles. No significant relationship was found between AoD and disease duration, pulmonary artery pressure or lung function tests. Conclusions, Presence and severity of Sar are associated with reduced aortic distensibility, irrespective of the disease duration, pulmonary artery pressure and lung function. In addition, patients with Sar have increased LVM and impaired myocardial performance. [source]

Cardiac magnetic resonance imaging in the evaluation of cardiac sarcoidosis: an Australian single-centre experience

INTERNAL MEDICINE JOURNAL, Issue 2 2009
V. Manins
Abstract Background:, Cardiac involvement in systemic sarcoidosis is common; however, current diagnostic tools are imprecise. Recognition of cardiac sarcoidosis (CS) is important as it has a relatively poor prognosis. Gadolinium-enhanced cardiac magnetic resonance imaging (Gad-CMR) is emerging as an excellent technique in determining the presence of and extent to which cardiac muscle is affected by sarcoidosis. Methods:, A retrospective analysis was performed on all patients with biopsy-proven systemic sarcoidosis referred for Gad-CMR scanning to evaluate potential cardiac involvement. All patients also underwent an electrocardiogram, Holter monitor and echocardiography. Gallium-67 radionuclide investigation, positron emission tomography and cardiac biopsy were ordered at the discretion of the treating physician. Results:, Eleven of the 20 patients had Gad-CMR images supportive of the diagnosis of CS. Eight of these 11 patients met the Japanese Ministry of Health and Welfare (JMHW) criteria for the diagnosis of CS; three abnormal Gad-CME scans consistent with diagnosis of CS were seen in patients who did not meet JMHW criteria. No patients with normal Gad-CMR scan met JMHW criteria for CS. Conclusion:, These findings suggest that Gad-CMR is potentially superior to the JMHW criteria in the diagnosis of cardiac sarcoidosis.

Sarcoidosis presenting with granulomatous uveitis induced by pegylated interferon and ribavirin therapy for hepatitis C

INTERNAL MEDICINE JOURNAL, Issue 3 2008
K. K. L. Yan
Abstract Sarcoidosis is a systemic granulomatous disease that is triggered by an autoimmune process, and is now a well recognized but uncommon complication of antiviral therapy for Hepatitis C virus (HCV) infection, likely related to its immunomodulatory effects. The clinical presentation of HCV related sarcoidosis is as varied as systemic sarcoidosis, but ocular presentation alone has not been reported previously. We present a 23 year-old female who developed visual disturbances due to ocular sarcoidosis during the course of antiviral therapy for chronic HCV infection. Our case presentation is then followed by a review of the literature on the topic. We aim to stress the importance of screening for eye problems in following HCV patients undergoing antiviral therapy, and raise clinicians' awareness of sarcoidosis as a possible cause for eye problems even in the absence of respiratory complaints.

Sarcoidal granulomatous tenosynovitis of the hands occurring in an organ transplant patient

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 8 2007
J. Andrew Carlson
Six years after kidney-pancreas transplant, a 47-year-old white man developed multiple subcutaneous and tenosynovial nodules of hands and wrists, limiting mobility. Biopsy of multiple nodules showed fibrosing, sarcoidal granulomas, some of which contained pigmented material. Microbiology, immunohistochemistry, scanning electron microscopy with backscattered electron imaging and energy dispersive X-ray analysis and polymerase chain reaction assays failed to show any infectious agents or foreign material. There was no historical, clinical or laboratory evidence of systemic sarcoidosis. It is not known whether the donor had sarcoidosis. Despite empiric antimycobacterial therapy and ongoing immunosuppressive therapy (corticosteroids, mycophenolate, cyclosporine), the man has progressively developed more nodules, limiting hand function. Sarcoidosis occurring in non-donor tisssue post-transplantation is an exceedingly rare complication of transplantation. We discuss this case and review the literature on sarcoidal tenosynovitis and sarcoidosis occurring post-transplantation. [source]

True blue football fan: Tattoo reaction confined to blue pigment

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2010
Corinne Yoong
ABSTRACT A tattoo reaction which appeared solely on the blue pigment of a 6-month old red and blue football club tattoo of an ardent fan was investigated. The patient was otherwise asymptomatic and no other abnormality was detected on full physical examination. Histology revealed a florid sarcoidal granuloma reaction to blue pigment. Preliminary investigations for systemic sarcoidosis did not reveal any abnormality. The tattoo reaction flattened clinically with the institution of a short course of topical mometasone furoate 0.1% ointment and as the subject remained asymptomatic, close surveillance for the development of systemic sarcoidosis is to continue. The possibility of delayed type hypersensitivity is discussed. [source]

Subcutaneous sarcoidosis,clinicopathological study of 10 cases

BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2005
J. Marcoval
Summary Background, Subcutaneous sarcoidosis is a specific cutaneous lesion of sarcoidosis that is rarely reported. Objective, Our purpose was to analyse the clinicopathological features of 10 patients with subcutaneous sarcoidosis and its relationship with the systemic features of the disease. Patients and methods, The patients with systemic sarcoidosis, diagnosed from 1974 to 2002 at a university hospital in Barcelona, Spain, who developed subcutaneous involvement, were included in the study. The diagnosis of systemic sarcoidosis was made according to conventional criteria. All the patients were monitored prospectively at the sarcoidosis clinic of the hospital. Skin biopsies were performed when granulomatous cutaneous involvement was suspected clinically. Results, Granulomatous cutaneous involvement was demonstrated in 85 of 480 patients with systemic sarcoidosis. In 10 of these 85 patients subcutaneous sarcoidosis was diagnosed (11·8%). The lesions were most frequently located in the extremities, involving the forearms in nine patients. Indurated linear bands from the elbow to the hand were observed in five patients. In all of our patients the subcutaneous nodules appeared at the beginning of the disease. In six patients, the nodules remitted spontaneously in less than 2 years. In two cases foreign particles were detected under polarized light. Conclusions, Subcutaneous sarcoidosis is a quite uniform clinicopathological entity usually appearing at the beginning of the disease. It usually heralds forms of sarcoidosis with nonsevere systemic involvement and is not associated with chronic fibrotic disease. [source]

Neuro-ophthalmological findings in sarcoidosis

ACTA OPHTHALMOLOGICA, Issue 6 2004
Kjell Heuser
Abstract. Purpose:,This review emphasizes the importance of neuro-ophthalmological signs and symptoms in sarcoidosis. The presence of ophthalmological and neuro-ophthalmological findings may lead to diagnosis of the disease and the initiation of adequate treatment. Material and Methods:,Patients who had been diagnosed with neurosarcoidosis during the period 1990 , 2001 were identified from the departmental diagnostic index. The history, clinical, laboratory and imaging data of patients were analysed. Results:,Fifteen patients were identified, four men and 11 women, with a mean age of 44.1 years (range 26,65 years). In six of the 15 (40%), neurological deficits were the initial symptoms. Nine (60%) had known sarcoidosis at the time of presentation. Ten patients (66%) had ophthalmological/neuro-ophthalmological symptoms and signs. Conclusion:,Neuro-ophthalmological symptoms may develop early in neurosarcoidosis. If neuro-ophthalmological symptoms arise in patients with established biopsy-proven sarcoidosis, the diagnosis is usually easy to make. However, a number of patients with neurosarcoidosis may present with neuro-ophthalmic symptoms before systemic involvement becomes obvious. In this situation the diagnosis is challenging, and the major goal is to establish the presence of systemic sarcoidosis. [source]

Cutaneous annular sarcoidosis developing on a background of exogenous ochronosis: a report of two cases and review of the literature

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 4 2010
M. J. Moche
Summary 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. [source]
