Radiographs of 175 patients with diffuse idiopathic skeletal hyperostosis (DISH) of the spine or ankylosing spondylitis were reviewed. DISH most frequently began in the middle and lower portions of the thoracic spine; it was rare in the upper portion. A few vertebrae were first affected, and then involvement extended, sometimes throughout the thoracic spine. The anterior and lateral aspects of vertebral bodies were mainly affected. Hyperostosis vertically spanning the anterior aspects of the vertebrae varied in thickness up to 10 mm, and the rate at which the hyperostosis proliferated was not specific for any vertebra. Males were 12 times more frequently affected than females, especially in the older age groups. Diabetes mellitus and hypertension have reportedly been associated with DISH, but no such correlation was found in this study. Despite the existence of criteria for differential diagnosis, it is sometimes difficult to distinguish ankylosing spondylitis from DISH radiologically. The radiologic features helpful in the differential diagnosis are described, and a review of the pertinent literature is included.

Coinciding investigations of the 85Sr test and of bone derived serum alkaline phosphatases activity were undertaken in 38 patinets with locomotor system diseases. In 15 patients there was congruence between the positive result of the 85Sr test and an increased activity of B-ALP. In 5 patients there was congruence between negative outcome of B-ALP and negative 85Sr test. The activities of T-ALP, B-ALP, L-ALP and I-ALP were compared with a group of 124 healthy controls. The causes of 18 incongruent results were analysed. In rhizomelic form of ASp, active Paget's disease, osteomalacia and in some forms of osteoporosis there was congruence between increased activity of B-ALP and the positive 85Sr test over the clinically involved area of the locomotor system. In ankylosing spondylitis (without rhizomelic involvement) there may be a moderate fall of B-ALP activity but the 85Sr test is usually positive; this may correspond with metabolic activity in the paravertebral region of the ligaments. Low B-ALP activity and positive 85Sr test in MP may refer to a latent process in the bone apparatus without marked activity of osteoblasts. The fall of B-ALP may be a result of therapy or due to the reduced capacity of B-ALP to be released from the bone. In osteomalacia the rapid fall of 85Sr activity during the test is the cause by the presence of pathological osteoid which may be, even in patients with hypertension, of renal origin. A method was described permitting the evaluation of the process of active incorporation of bone minerals (after 8 days). The activity of the 85Sr test over clinically silent areas (e.g. spine) may indicate a decompensated process in the spine due to an involvement to the large joints. The two methods used in this study are metabolically different (85Sr binds to proteoglycans and inorganic structures of bone tissue, alkaline phosphatase to the activity of osteoblasts) and prove to be clinically valuable. Detailed analysis of the results makes it possible to define the stages of clinical activity of disease and to check more exactly the efficiency of the therapeutic method.

Indentations of the glomerular basement membrane were observed by light microscopy in ultrathin Epon-embedded serial sections from the renal biopsies of patients who had membranous glomerulonephritis, minimal change glomerulonephrits, acute or resolving exudative glomerulonephritis and focal glomerulonephrits, interstitial nephritis, amyloidosis, rheumatoid arthritis, or ankylosing spondylitis. In patients with membranous glomerulonephritis, acute or resolving exudative glomerulonephritis, amyloidosis, or rheumatoid arthritis, the occurrence of indentations in the glomerular basement membrane differed significantly from that in controls. The presence of indentations did not correlate with proteinuria, hematuria, leukocyturia, arterial hypertension, or with the nephrotic syndrome or its treatment with steroids. Examination of alternate serial sections by light and be electron microscopy showed that the indentations that were light microscopically visible corresponded to craters on the epithelial surface of the glomerular basement membrane seen in the electron microscope. These craters contained protruding portions of the epithelial cells, extracellular electron-lucent material or electron-dense amorphous or striated membranous material. They were often surrounded by spikelike protrusions of the lamina densa. These indentations might represent solitary remnants of former subepithelial deposits.

Echocardiography has been useful in the evaluation of congestive and hypertrophic cardiomyopathies. We present echocardiographic findings in seven patients with infiltrative cardiomyopathy due to amyloid. Cardiac amyloidosis was documented at autopsy in two patients, and the diagnosis was suggested by clinical, echocardiographic, tissue, or hemodynamic findings in the other five. Hemodynamic findings in three patients mimicked constrictive pericarditis; and autopsy was performed on one of the three and showed a normal pericardium. Underlying disorders were multiple myeloma (five patients), ankylosing spondylitis (one patient), and an unknown disorder (one patient). The basic echocardiographic findings in infiltrative cardiomyopathy due to amyloid were (1) symmetrically increased left ventricular wall thickness (in the absence of hypertension or aortic valvular disease), (2) hypokinesia and decreased systolic thickening of the interventricular septum and left ventricular posterior wall, and (3) small to normal size of the left ventricular cavity. Two patients also had small pericardial effusions. Thus, in a patient with congestive heart failure, these echocardiographic findings should suggest infiltrative cardiomyopathy.

Cardiac function was investigated in men with ankylosing spondylitis (AS) age 21-65 years who had no cardiorespiratory symptoms or known abnormalities of heart or lungs. Chest radiographs and standard electrocardiograms were normal in 73 of 74 subjects. In echocardiographs of 30 men, left atrial size and left ventricular cavity size and wall thickness were normal. Minor abnormalities in the valve roots were present in 3 older men. Early diastolic abnormalities of the left ventricle were demonstrated in 16 of 30 subjects. This finding was confirmed by repetition of the echocardiography a year later in 15 subjects and by comparison of 11 probands with their healthy brothers. Myocardial tissue obtained at necropsy from 28 AS patients without ischaemic or valvular heart disease or hypertension was studied. A mild, diffuse increase of interstitial connective tissue was seen but there was no inflammatory change or amyloid. Computerised image analysis showed 30.7% interstitial reticulin compared with 17.7% in age/sex matched controls (p less than 0.0001).

A defined general population of 159,200 male and female native Swedes born in the period of 1911-1940, from an urban catchment area of the then only general hospital, was followed over a decade (1970-1979) with regard to inpatient hospitalization for all kinds of diagnoses. Psoriasis cases (n = 372) are significantly (p less than 0.001) associated with a spectrum of diseases: male as well as female psoriatics seem to show excess rates of viral infections, alcoholism, hypertension, pneumonia, liver cirrhosis, urticaria, and rheumatoid arthritis. Psoriasis in males only seem to be associated with iritis and ankylosing spondylitis, whereas psoriasis in females only is associated with lung cancer, diabetes, obesity, myocardial infarction and asthma.

Forty patients, 30 men and 10 women with an average age of 38.47 +/- 11.07 years, suffering from ankylosing spondylitis and attending a Rheumatology Outpatient Clinic, were evaluated for cardiovascular involvement. The evaluation was based on patients' clinical observation, electrocardiography, echocardiography, and chest x-ray. More than a simple review, this study was undertaken with the aim of arriving at a better clinical definition of the cardiovascular manifestations found in ankylosing spondylitis. In fact, of the 40 patients, 8 (20%) had systemic hypertension for which an explanation could not be found, 4 of whom were less than forty-five years old; the echocardiogram showed mitral valve prolapse in 4 patients (10%), 2 of them with a systolic murmur and other 2 with a protosystolic click on auscultation. More significant than the changes in conduction was the finding of a sinus bradycardia in 9 patients (22.5%), and a PR interval below 120 msec in 3 patients (7.5%). The authors conclude that the extension of cardiovascular changes in ankylosing spondylitis is more vast than usually acknowledged.

A case of a 48 years old man with a combination of immunoglobulin A glomerulonephritis and ankylosing spondylitis is reported. The patient presents with the typical clinical and X-ray data of Bechterew's disease and the kidney biopsy shows diffuse mesangioproliferative glomerulonephritis with IgA precipitates. The rheumatic manifestations precede the hematuria and proteinuria. High serum IgA and arterial hypertension are present. It is suggested that the combination of these two diseases is more frequent since common pathogenetic mechanisms may play a leading role.

In this review, the cardiac lesions which develop in association with the various collagen-vascular diseases are described. In rheumatoid arthritis, the most frequent lesions are: fibrous obliterative pericarditis, with pericardial deposits of calcium, fibrin, cholesterol, and rheumatoid granulomas; granulomatous or nonspecific myocarditis; valvulitis, vasculitis, and amyloid deposits. In ankylosing spondylitis, the lesions involve mainly the valves (aortic and mitral valves) and the aorta. In systemic lupus erythematosus, the predominant cardiovascular lesions are: pericarditis, Libman-Sacks endocarditis, nonspecific myocarditis, vasculitis with fibrinoid necrosis, and acceleration of atherosclerosis. In scleroderma, the main cardiac lesion is fibrosis with only scanty inflammatory cells; pericarditis and nonbacterial thrombotic endocarditis also occur. In dermatomyositis/polymyositis, fibrous or fibrinous pericarditis can occur, as well as myocarditis with infiltrates of lymphocytes and plasma cells and with degeneration and necrosis of myocytes; valvulitis is uncommon except when the disease is related to mucinous adenocarcinoma. In polyarteritis nodosa, various stages of necrotizing vasculitis involve all layers of the arterial walls; foci of myocardial necrosis of various sizes can occur in association with these lesions; cardiac hypertrophy related to hypertension and pericarditis related to uremia, may also be found. In Wegener's granulomatosis, pericarditis, inflammatory infiltrates, necrotizing granulomas, and vasculitis have been observed in the heart.

This two-part article examines the histologic and morphologic basis for stenotic and purely regurgitant aortic valves. Part I discusses stenotic aortic valves and Part II will discuss causes of purely regurgitant aortic valves. In over 95% of stenotic aortic valves, the etiology is one of three types: congenital (primarily bicuspid), degenerative, or rheumatic. Other rare causes of stenotic aortic valves include active infective endocarditis, homozygous type II hyperlipoproteinemia, and systemic lupus erythematosis. The causes of pure aortic regurgitation are multiple but can be separated into diseases affecting the valve (normal aorta) (infective endocarditis, congenital bicuspid, rheumatic, floppy), diseases affecting the walls of aorta (normal valve) (syphilis, Marfan's, dissection), disease affecting both aorta and valve (abnormal aorta, abnormal valve) (ankylosing spondylitis), and diseases affecting neither aorta nor valve (normal aorta, normal valve) (ventricular septal defect, systemic hypertension). Diseases affecting the aortic valve alone are the most common subgroup of conditions producing pure aortic valve regurgitation.
