This study was conducted to determine the prevalence of subclinical entheseal involvement at the greater trochanter level
by ultrasound in patients with spondyloarthritis. Forty-six patients with spondyloarthritis and 46 healthy age- and sex-matched
controls were studied. All patients with no clinical evidence of enthesopathy at the greater trochanter underwent an ultrasound
examination. The following three entheses were scanned bilaterally: anterior insertion of gluteus minimus, anterior insertion
of gluteus medius, and posterior insertion of gluteus medius. Ultrasound findings of enthesopathy were thickening, calcifications,
bone erosions, enthesophytes, bursitis, and power Doppler signal. A total of 276 entheses were evaluated in spondyloarthritis
patients. In 112 out of 276 (40.5%), grayscale ultrasound found enthesopathy. The enthesis with the highest number of signs
of enthesopathy was the anterior insertion of gluteus medius (46/276) (16%), followed by posterior insertion of gluteus medius
(37/276) (13.4%) and anterior insertion of gluteus minimus (29/276) (10.5%). In the healthy population, ultrasound found entesopathy
in 80 out of 276 (29%) entheseal sites (p < 0.0001). Posterior insertion of gluteus medius enthesis was the more frequently involved (34/276) (12.3%), followed by
anterior insertion of gluteus medius (24/276) (8.6%) and anterior insertion of gluteus minimus (22/276) (7.9%). Power Doppler
was found more frequently in patients with spondyloarthritis compared with healthy controls (1% vs 0%). Our results show a
higher prevalence of subclinical enthesopathy at the greater trochanter level in patients with spondyloarthritis than in age-
and sex-matched healthy controls. 相似文献

Patients with irritable bowel syndrome have greater pain tolerance than normal subjects 总被引:18,自引:0,他引:18
A low tolerance for pain has been postulated as a factor in the expression of symptoms in patients with irritable bowel syndrome. This has been based on previous work demonstrating reduced intestinal thresholds for rectal pain induced by balloon distention in patients with irritable bowel syndrome. As the disease may alter the rectal response to distention, inferences regarding pain perception and reporting behavior cannot be drawn from these data. In this study, using electrocutaneous stimulation, we found that patients with irritable bowel syndrome had pain reporting behavior comparable to patients with Crohn's disease. Both patient groups were less likely than normals to report a noxious stimulus as painful. This suggests that pain perception and reporting is attenuated in patients with chronic abdominal pain and, accordingly, a generalized reduction in the threshold for reporting pain is not a factor in the expression of symptoms in the irritable bowel syndrome. 相似文献

Leprosy patients lack specific cellular immunity against Mycobacterium leprae, but other immunological functions are thought to be preserved. However, in a leprosy sanatorium in South Japan between 1982 and 2000, we found that the average age at death of cured lepromatous leprosy patients was about 5 yrs younger than that of cured tuberculoid patients; [male/lepromatous, 76.0 +/- 10.0 yrs old vs. male/tuberculoid, 79.7 +/- 9.4 yrs old, p = 0.026], and [female/lepromatous, 78.0 +/- 10.5 vs. female/tuberculoid, 85.3 +/- 9.8, p = 0.0001]. This trend was also observed in autopsy records of two other leprosy sanatoria in Japan. In a prospective study based on their age in 1982, among females in the age group between 60 and 69, lepromatous patients (75.3 +/- 6.0 yrs) died earlier than tuberculoid patients (81.0 +/- 5.1 yrs) (p < 0.01). These findings suggest that lepromatous patients have higher risk of death even in a post-chemotherapy era. 相似文献

BackgroundEntheseal involvement is a frequent and distinctive feature of psoriatic arthritis (PsA). It is detected clinically but lacks sensitivity and reliability. Musculoskeletal ultrasound (MSUS) is an important tool for accurate detection of enthesitis.Aim of the workTo determine the frequency and distribution of subclinical entheseal abnormalities at lower limbs using MSUS in patients with psoriasis for early detection of PsA, and to evaluate its relation to disease severity.Patients and methods80 patients with psoriasis were studied. Psoriasis Area and Severity Index (PASI) was assessed. High-resolution MSUS assessment of quadriceps, patellar and Achilles tendons, and plantar fascia entheses was performed. Glasgow Ultrasound Enthesitis Scoring System (GUESS) was assessed.ResultsThe median (interquartile range; difference between 75th and 25th quartile) age of the patients was 46(26.3) years and were 42 males. The disease duration was 9(12) years, PASI was 10.9(18.9), and GUESS 6(4). Nail dystrophy was found in 48(60%). Clinical enthesitis was found in 15(18.8%) patients; MSUS revealed lower limb enthesopathy in at least one enthesis in 76(95%) patients, and abnormality in 421 of 800 entheses (52.6%). Distal insertion of the patellar tendon was the most frequently involved (68.8%). GUESS significantly correlated with the age, body mass index (BMI), and PASI.ConclusionPsoriasis is associated with a relevant frequency of asymptomatic entheseal abnormalities. MSUS is a valuable, simple, and noninvasive tool in early detection of enthesopathy in psoriatic patients, especially in the presence of older age, high BMI, and high PASI as potential parameters for detection of psoriatic enthesitis. 相似文献

BACKGROUND & AIMS: Nonselective beta-blockers are effective in reducing portal pressure in cirrhotic patients. However, this beneficial effect is highly variable and may depend on the extent of portal system collateralization. The aim of this study was to compare portal pressure response with timolol, a nonselective beta-blocker, in cirrhotic patients with and without varices. METHODS: Portal and systemic hemodynamics were measured before and after a single oral dose of 10 mg of timolol in 50 patients with cirrhosis and portal hypertension, 15 with and 35 without esophageal varices. RESULTS: Timolol significantly decreased portal pressure in all patients (mean reduction, 20% +/- 13%; P < 0.0001). The reduction in hepatic venous pressure gradient was greater in patients without varices (-24% +/- 14%) than in those with varices (-12% +/- 8%) (P < 0.01). A decrease in the hepatic venous pressure gradient of <12 mm Hg was achieved in 7 of 12 (58%) patients without varices and a baseline pressure gradient of <12 mm Hg, but only in 3 of 15 patients with varices (20%) (P < 0.01). CONCLUSIONS: Timolol is effective in reducing portal pressure in cirrhotic patients, more so in patients without varices, suggesting that nonselective beta-blockers will be more effective in the treatment of portal hypertension when administered at early stages, before the development of varices.

OBJECTIVE: We investigated the clinical features of Korean patients with adult-onset ankylosing spondylitis (AAS) and examined the differences between AAS patients with and without peripheral joint disease (PJD). METHODS: We studied 67 consecutive patients with primary AAS who visited the rheumatology clinic of a tertiary referral hospital. All patients experienced joint symptoms after the age of 15 and fulfilled the modified New York criteria for ankylosing spondylitis. Hips and shoulders were not considered as peripheral joints. RESULTS: The male-to-female ratio was 8.6:1.0. Mean age at disease onset was 22.3 +/- 5.5 (mean +/- s.d.) yr and disease duration was 10.8 +/- 8.0 yr. Spinal symptoms were the first manifestations in 80.6% of patients. During the disease course, hip, shoulder and peripheral joint involvement were found in about 60% of patients. In patients with PJD, the most commonly affected joints were the knees and ankles. The pattern of PJD, in most cases, was asymmetrical and mono/oligoarticular. AAS patients with PJD had fewer spinal symptoms than those without PJD as a presenting feature (71.8 vs 92.9%, P = 0.035). The modified Schober test showed greater increments in patients with PJD (4.9 +/- 2.4 vs 3.0 +/- 2.4 cm, P = 0.002). Forced vital capacity was better in patients with PJD (79.0 +/- 11.4 vs 70.8 +/- 15.5% of predicted value, P = 0.016). Totally ankylosed sacroiliitis, spinal squaring and syndesmophytes on radiographs were less common in the patients with PJD than in those without PJD (33.3 vs 64.2%, P = 0.012; 20.5 vs 67.9%, P = 0.000; and 38.5 vs 71.4%, P = 0.008, respectively). CONCLUSION: Peripheral joints as well as shoulder and hip joints were more frequently involved during the disease course in Korean AAS patients compared with earlier reports in Caucasians. The general joint involvement pattern of PJD was similar to patterns reported previously. Our data suggest that, clinically and radiographically, AAS patients with PJD have a less severe spinal disease course than those without PJD. 相似文献

OBJECTIVE: To confirm the association of visceral obesity and brachial-ankle pulse wave velocity (baPWV) and to compare metabolic indices and baPWV between individuals who have normal body weight but are viscerally obese and individuals with excessive body weight who are not viscerally obese. PATIENTS AND MEASUREMENTS: We recruited a total of 150 women, aged 22 to 67 years. We assessed body composition, measured by computed tomography (CT), and divided the study population into four groups, based on visceral adipose tissue area (normal, normal body weight but viscerally obese, excessive body weight but not viscerally obese, and excessive body weight and viscerally obese). The baPWV was measured, using a volume plethysmographic instrument. RESULTS: Despite lower levels of total body fat, the women who had a normal body weight but were viscerally obese had a higher plasma triglyceride level and baPWV measurement and greater subcutaneous fat area (SFA) and thigh SFA than the women with excessive body weight who were not viscerally obese. After adjustment for age, mean blood pressure (BP), body mass index (BMI), triglyceride levels, fasting insulin levels, and free fatty acid (FFA) levels, baPWV was independently correlated with abdominal visceral fat area, as measured by CT (P = 0.001). CONCLUSIONS: Mean baPWV was higher in women with normal body weight who were viscerally obese than in women who had excessive body weight but were not viscerally obese, and abdominal visceral fat was an independent factor for baPWV. These results suggest that early detection and intervention in viscerally obese individuals, even those within a normal BMI range, could be needed to prevent atherosclerosis and cardiovascular disease (CVD). 相似文献

The painful vaso‐occlusive crises (VOC) that characterize sickle cell disease (SCD) progress over hours from the asymptomatic steady‐state. SCD patients report that VOC can be triggered by stress, cold exposure, and, pain itself. We anticipated that pain could cause neural‐mediated vasoconstriction, decreasing regional blood flow and promoting entrapment of sickle cells in the microvasculature. Therefore, we measured microvascular blood flow in the fingers of both hands using plethysmography and laser‐Doppler flowmetry while applying a series of painful thermal stimuli on the right forearm in 23 SCD patients and 25 controls. Heat pain applied to one arm caused bilateral decrease in microvascular perfusion. The vasoconstriction response started before administration of the thermal pain stimulus in all subjects, suggesting that pain anticipation also causes significant vasoconstriction. The time delay between thermal pain application and global vasoconstriction ranged from 5 to 15.5 seconds and increased with age (P < .01). Although subjective measures, pain threshold and pain tolerance were not different between SCD subjects and controls, but the vaso‐reactivity index characterizing the microvascular blood flow response to painful stimuli was significantly higher in SCD patients (P = .0028). This global vasoconstriction increases microvascular transit time, and may promote entrapment of sickle cells in the microvasculature, making vaso‐occlusion more likely. The rapidity of the global vasoconstriction response indicates a neural origin that may play a part in the transition from steady‐state to VOC, and may also contribute to the variability in VOC frequency observed in SCD patients. 相似文献

BACKGROUND: It is recommended that lovastatin be avoided in patients with unexplained elevation in transaminase levels. However, there are no studies that evaluated the risk of lovastatin hepatotoxicity in subjects with elevated liver enzymes. Our study tested the hypothesis that patients with elevated liver enzymes are not at higher risk for hepatotoxicity from lovastatin. METHODS: Our study consisted of the following three cohorts of patients seen between December 1987 and December 1998: cohort 1: 135 patients with elevated baseline enzymes (aspartate transaminase [AST] >40 IU/L or alanine transaminase [ALT] >35 IU/L) who received lovastatin; cohort 2: 620 patients without elevated liver enzymes who received lovastatin; and cohort 3: 2644 patients with elevated liver enzymes but not prescribed lovastatin. Elevations in liver biochemistries over a 12-month period after lovastatin was prescribed were categorized into mild-moderate or severe elevations and into "Hy's Rule" based on published criteria. RESULTS: The incidence of mild-moderate elevations and severe elevations in liver biochemistries in cohort 1 were 6.6% and 0%, respectively. Compared with cohort 2, individuals in cohort 1 had higher incidence of mild-moderate elevations (6.6% versus 3%; P = 0.03) but not severe elevations (0% versus 0.3%; P = 0.9). Compared with cohort 3, patients in cohort 1 had similar mild-moderate elevations (6.6% versus 11%; P = 0.2) but lower severe elevations (0% versus 5.5%; P < 0.01). No one in cohorts 1 or 2 developed elevations meeting Hy's Rule, whereas 3.5% of the patients in cohort 3 exhibited such elevations (P < 0.05 versus cohort 1 or cohort 2). CONCLUSIONS: Significant hepatotoxicity from lovastatin was very infrequent in this study, and individuals with elevated baseline liver enzyme levels did not have higher frequency of lovastatin hepatotoxicity than those with normal liver enzyme levels. 相似文献

AIMS: High androgen levels are presumed by many to explain the male predisposition to coronary artery disease. However, natural androgens inhibit male atherosclerosis(1). Our aim was to determine whether levels of androgens differ between men with and without coronary artery disease. METHODS AND RESULTS: Ninety male subjects (60 with positive, and 30 with negative coronary angiograms) were recruited. Early morning, fasting blood samples were taken from each patient and free, total and bioavailable testosterone, sex hormone binding globulin, oestradiol, and lipids were measured. Bioavailable testosterone was assayed using a modified technique. Free androgen index was calculated. Men with coronary artery disease had significantly lower levels of free testosterone (mean (standard deviation)); 47.95 (13.77) vs 59.87 (26. 05) pmol. l(-1), P=0.027), bioavailable testosterone; 2.55 (0.77) vs 3.26 (1.18) nmol. l(-1), P=0.005 and free androgen index; 37.8 (10. 4) vs 48.47 (18.3), P=0.005, than controls. After controlling for differences in age and body mass index the differences in free androgen index and bioavailable testosterone remained statistically significant (P=0.008 and P=0.013, respectively). CONCLUSION: Men with coronary artery disease have significantly lower levels of androgens than normal controls, challenging the preconception that physiologically high levels of androgens in men account for their increased relative risk for coronary artery disease. 相似文献

To evaluate the effect of age on the pattern of circadian blood pressure after nifedipine tablets, ambulatory blood pressure after administration of low and high doses of nifedipine, taken twice daily, was measured over a 24-hour period in 10 elderly and 8 young hypertensive patients. After a 2-week control period without antihypertensive drug, 10 mg of nifedipine was administered twice daily for 2 weeks (low-dose period), followed by 2 weeks of 20 mg (high-dose period). At the end of each period, ambulatory BP monitoring was conducted every 30 minutes for 24 hours, using an ABPM 630 (Nippon-Colin, Komaki, Japan). In both groups, averages of systolic and diastolic BP for the entire day decreased significantly from the control to the low-dose periods. However, after the high-dose period, only the elderly group had further significant reduction of systolic BP, whereas no further reduction was seen in the young group. Separate analysis of whole-day data into daytime and nighttime values revealed that a further decrease in systolic BP after the high-dose period in the elderly group was a reflection of nighttime decline. It was suggested that circadian BP patterns after administration of nifedipine tablets in the elderly differed from those in young hypertensive patients, especially after administration of the high-dose. 相似文献

Enterokinase was measured in peroral intestinal biopsies showing normal histology and in those from untreated coeliac patients which showed gross villous atrophy. There was no significant difference in the specific activity of enterokinase between these two groups. These results do not support the recent hypothesis that enterokinase is a brush border enzyme, but would be consistent with the idea that it is adsorbed to the cell membrane following secretion. 相似文献

Van Buchem disease is an autosomal recessive disease characterized by overgrowth of the skeleton. In a group of Dutch patients the disease is thought to be due to a 52-kb deletion that results in decreased expression of the SOST gene. To further characterize the disease, the morphology of the metacarpals of six adult subjects and two juveniles with Van Buchem disease were measured on hand x-rays along with nine normal adults and nine adult carriers of the disease. Serum bone formation markers, alkaline phosphatase, type I procollagen peptide, and osteocalcin, and the urinary bone resorption marker, cross-linked N-telopeptide, were determined. Van Buchem patients had increased metacarpal outer diameter, inner diameter, cortical thickness, and bone mineral density. Calculated bone volume and derived polar moment of inertia were markedly elevated (elevations of 158 +/- 33% and 497 +/- 95%, respectively) consistent with increased bone strength. Serum procollagen peptide and osteocalcin were significantly higher in Van Buchem patients. Urinary cross-linked N-telopeptide was significantly elevated in Van Buchem patients. None of these changes was found in Van Buchem carriers. These observations indicate that decreased expression of the SOST gene can lead to increased bone formation and to stronger bones. 相似文献
