Five main acid phosphatase (AcP) zones have been recognized and studied by polyacrylamide-gel electrophoresis. Band 5 represents the only tartrate-resistant form and is present in bone osteoclasts and in human alveolar macrophages (AMs). This study was carried out to quantify the presence of total
Alveolar macrophages differ from their percursors in blood, monocytes, by expressing strong activity of the tartrate resistant variant of acid phosphatase (TAcP). A study was carried out to analyse the expression of this enzyme cytochemical marker by alveolar macrophages from bronchoalveolar lavage
OBJECTIVE
Tartrate-resistant acid phosphatase (TRACP) 5a is expressed strongly in inflammatory macrophages (MΦ). Serum TRACP5a is elevated in rheumatoid arthritis patients with extra-articular manifestations of rheumatoid nodules, in a percentage of patients with end-stage chronic kidney disease,
The development of the syndrome of chronic intrahepatic cholestasis in five young, black men who had systemic granulomatous disease and clinical features consistent with those of sarcoidosis is described. Clinical and biochemical aspects, similar to those of primary biliary cirrhosis, included
Immunohistological observations of lymphoid and non-lymphoid cell subsets in biopsies of sarcoid skin granulomas have been compared with positive Kveim tests and the sites of PPD injection in sarcoid patients. Monoclonal antibodies have been used in indirect immunofluorescence often in combination
Cholangitis in patients with ulcerative colitis (UC) can lead to misdiagnosis of primary sclerosing cholangitis (PSC). Furthermore, it can mimic cholangiocellular carcinoma, which also can lead to inappropriate and potentially harmful treatment of the patient. An 18-year-old male patient with known
Sarcoidosis is a systemic noncaseous granulomatous disease. The liver is a common location but usually asymptomatic. Current literature suggests an association between sarcoidosis and cancers. However, there is a lack of definite evidence. We present a case of a 59-year-old man with jaundice and
METHODS
A 63-year-old man had for 10 months suffered from marked weight loss, night sweats, diffuse abdominal pain and increased stool frequency. He was admitted to evaluate an ultrasonically abnormal focus in the liver parenchyma and elevated liver function parameters. His sclerae were obviously
Elevation of serum-angiotensin-converting enzyme (serum ACE) in patients with active sarcoidosis was confirmed in a total of 64 subjects with a mean serum ACE of 15.76+/-7.4 units compared with 6.05+/-2.0 units in 194 patients with other types of respiratory disease. Resolution of the sarcoidosis
Sarcoidosis is a chronic multisystem disorder of unknown cause characterized by the presence of noncaseating epitheloid granulomas and derangement of the normal skin architecture. Though an array of organs may be affected by the disease the most common site of affection is the lung. An extrathoratic
A 39-year-old male reported fevers, weight loss, watery loose stools, and decreased visual acuity in his right eye over the prior five years. He was pancytopenic, had an elevated American council on exercise level, total bilirubin, and alkaline phosphatase. Computed tomography revealed massive
A 31-year-old man previously treated with chemotherapy for metastatic testicular cancer presented with new mediastinal lymphadenopathy and peripheral lung opacities. Serum tumour markers were not elevated and a PET (positron emission tomography) scan revealed increased FDG (fluoro-deoxyglucose)
