The purpose of the study was to correlate degree of hypocholesterolemia to changes in plasma levels of amino acids and other metabolic variables in severely injured septic patients. Measurements included plasma cholesterol, full amino-acidograms, acute phase proteins, complementary variables and blood cell counts. The Fischer plasma molar amino acid ratio (leucine+isoleucine+valine)/(phenylalanine+tyrosine) was calculated. Plasma cholesterol for all measurements (n=145) was 3.1+/-1.1 mmol/L and, upon entry in the study, it was correlated inversely with sepsis severity score (p<0.05). Along the clinical course, changes in cholesterol were clearly paralleled by opposite changes in C-reactive protein, which was the best correlate of cholesterol (r2=0.70, p<0.0001). Furthermore cholesterol was inversely related to phenylalanine, fibrinogen, lactate and white blood cell count, and directly to the Fischer molar amino acid ratio, cystathionine, methionine, glycine and transferrin (r2 between 0.36 and 0.15, p<0.0001 for all). Within this pattern of correlations, cholesterol was also directly related to alkaline phosphatase, which accounted for the effect of cholestasis, when present. For any given value of the other variables, cholesterol increased significantly with increase in alkaline phosphatase (p<0.0001). C-reactive protein (CRP, mg/dl) and alkaline phosphatase (ALKPH, U/L) together in the same regression explained 79% of the variability of cholesterol (CHOL, mmol/L): CHOL=5.90-0.74[Log(e)CRP]+0.004[ALKPH]; multiple r2=0.79, p<0.0001. Inclusion in this regression of other variables did not increase the r2. By using only amino acid variables, the best fit was provided by a regression including the Fischer ratio and cystathionine, which explained 55% of the variability of cholesterol (multiple r2=0.55 p<0.0001), and this result was not improved by the inclusion of other amino acids. These data show that severity of hypocholesterolemia in sepsis is quantifiably related to changes in plasma amino acids, and to severity of acute phase response and metabolic decompensation. More study is needed to understand whether hypocholesterolemia in sepsis has only diagnostic or prognostic implications, or that it may also contribute actively to worsening of the disease.

Heterotopic ossification is a frequent and potentially disastrous complication of acute spinal cord injury. Pathogenesis and etiology are not well described, initial clinical symptoms are uncharacteristic, specific laboratory findings do not exist. Between March 1997 and May 2000 all 290 patients admitted to our facility with acute spinal cord injury underwent standardized sonographic examinations of the soft tissue around the hip joint every three weeks, starting as early as two weeks after injury. In 12% of the patient population characteristic sonographic findings for heterotopic ossification were present while the regular x-ray examination was still unremarkable. Laboratory findings (alkaline phosphatase, C-reactive protein, anorganic phosphate) were unspecific. Clinical findings were present only in a few patients. All patients underwent radiotherapy consisting of the administration of 5 times 3 Gy to the area as soon as possible. Follow up demonstrated no progression of the heterotopic bone formation in these cases. In conclusion, regular ultrasound examination proved to be a secure, fast and reproducible method for the very early diagnosis of heterotopic ossification after acute spinal cord injury.

Factors involved in inflammation are linked with those critical for bone remodeling. We examined the association between serum high sensitivity C-reactive protein (hsCRP) levels and bone mineral density (BMD) in healthy women. Serum concentrations of hsCRP and total alkaline phosphatase (ALP) were measured in premenopausal ( n =3,662) and postmenopausal ( n =1,031) women aged 30 years or older. BMD was measured at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. According to the WHO definition, osteopenia was diagnosed at -2.5< T -score < -1.0 SD, and osteoporosis was diagnosed at T -score < or = -2.5 SD at any sites. Compared with normal subjects, log-transformed serum hsCRP levels were higher in osteopenic and osteoporotic subjects (all, P < 0.001) with linearity ( P for trend <0.001), after adjustment for age, BMI and menopausal status. Menopausal status did not have a significant interaction on the association ( P =0.457). In both premenopausal and postmenopausal women, serum total ALP levels were higher in the subjects with higher hsCRP quintiles than those with the lowest quintile (all, P for trend < 0.001). Multivariate-adjusted odds ratio (OR) for osteoporosis and osteopenia were 1.35 (95% CI, 1.08 to 1.68) in the highest hsCRP quintile of premenopausal women, and OR for osteoporosis was 1.54 (95% CI, 1.10 to 2.53) in the highest hsCRP quintile of postmenopausal women. These findings suggest that subclinical systemic inflammation may be associated with bone turnover rate and bone mass in healthy women.

Back pain, especially in the lumbar region is a frequent symptom in ambulatory medicine. The differential diagnosis is wide and ranges from rather harmless muscular distortions to systematic disease, such as chronic infections or cancer. Our case shows, that sometimes the diagnosis is not quite simple to determine. A atypically picture may lead to unnecessary further evaluations and in some case even invasive diagnostic tests. However, the benefit should overweight the harm and costs. Not every back pain needs to be examined in every case and with every diagnostic possibility. Recent guidelines recommend a conservative approach to patients with back pain if they are younger than 50 years of age and if cancer or chronic infection is not suspected from their clinical evaluation and past medical history. For patients older than 50 years of age and suspicion for systematic disease, a radiograph of the spine and a routine laboratory measurement, including markers of inflammation (e.g. C-reactive protein), alkaline phosphatase, PSA (prostate-specific antigen) and immune-electrophoresis is mandatory. More detailed diagnostic steps, e.g. CT or MRT, should be performed if symptoms persist for longer than 6 weeks. In addition, if symptoms do not resolve with analgesia and physiotherapy more invasive therapeutically options may be considered.

This structured review discusses the current literature on selected biomarkers and their ability to predict preterm delivery (PTD). Among symptomatic women, the likelihood ratio (LR+) for the prediction of PTD was found to be greater than 10 using amniotic fluid (AF) interleukin-6 (IL-6), AF Ureaplasma urealyticum, as well as a multi-marker consisting of cervical IL-6, cervical IL-8, and cervical length (CL). The LR+ was found to be between 5 and 10 for serum C-reactive protein (CRP). An LR+ between 2.5 and 5 was recorded for serum corticotropin-releasing hormone (CRH), cervical fetal fibronectin (fFN), cervical IL-6, serum relaxin, and a multi-marker consisting of fFN and CL. CL and bacterial vaginosis (BV) both predicted PTD in women with preterm labor with an LR+ of less than 2.5. In asymptomatic women, AF U. urealyticum and a multimarker consisting of five individual markers [fFN, CL, serum alpha-fetoprotein (AFP), serum alkaline phosphatase, and serum granulocyte colony-stimulating factor (G-CSF)] predicted PTD with an LR+ greater than 10. The LR+ was between 5 and 10 for serum relaxin and CL. LRs+ recorded for serum alkaline phosphatase, salivary estriol, serum CRH, serum G-CSF, cervical IL-6, AF IL-6, cervical fFN, AFP, and Chlamydia all ranged between 2.5 and 5. Finally, an LR+ below 2.5 has been documented for serum ferritin, serum CRP, BV, and cervical ferritin.

The aim of the study was to determine factors of risk and progress of aortal valvular calcinosis (AVC) and aortic ostium stenosis (AOS). The subjects were 85 patients with AVC (42--with aortic valvular stenosis (AVS), and 43--without AOS). The study, which included analysis of the lipid and mineral metabolism, and immunological tests, shows that potential factors of AVC are: age (p < 0. 001), osteoporosis (p < 0.03), mitral ring calcification (p = 0.047), dislipidemia (high serum level of total cholesterol, cholesterol of low density lipoproteins, and apoB, atherogenic shift of apoB/apoA-1 ratio, low level of cholesterol of high density lipoproteins (CHDLP)), disbalance between intecellular matrix synthesis and destruction (high concentration of alkaline phosphatase and its bone fraction, and accelerated deoxypyridinoline excretion), inflammation (high concentration of C-reactive protein (CRP), fibrinogen, and interleukin-6 (IL-6)). The factors of AOS were: age (p < 0.001), smoking (p < 0.001), osteoporosis (p = 0.004), AVC (p < 0.001), mitral ring calcinosis (p = 0.033), dislipidemia (high levels of cholesterol of low density and very low density lipoproteins, low concentrations of CHDLP, and apoA-1), degradation of extracellular matrix, and inflammation (high concentrations of CRP, fibrinogen, IL-6, and IL-8). Thus, atherogenic dislipidemia and mineral dysmetabolism disorder facilitate AVC. The revealed immune status changes imply the role of inflammation in the development and progress of AVS.

A 26-year-old man was admitted to the department of surgery of our hospital with a complaint of intermittent left leg pain for the past two weeks. Ultrasonography revealed reduced blood flow to the tibial artery, which suggested a vascular disease like arteriosclerosis obliterans. Enhanced computed tomography (CT) revealed a huge abdominal tumor and a 3-dimensional CT scan showed a feeding artery from the left renal artery to the huge tumor. Findings of routine blood and urine examinations were elevated levels of lactate dehydrogenase, alkaline phosphatase, and C-reactive protein. Surgical exploration revealed a giant tumor with clouded ascites in the abdominal cavity containing class V cells revealed by cytological examination. The tumor was easily resected. Its vascular pedicle was thick and hypertrophied. Thus, it could be traced to the origin of left gonadal artery. At this time, the surgeon incidentally noticed the absence of left testis in the patient's scrotum. The resected specimen was 25 x 18 x 12 cm in size, and it weighed 3000 gm. The histological finding was pure seminoma invaded to peritoneum. His leg pain was relieved after the tumor resection.

The outcome of a patient with giant cell arteritis (GCA) is closely related to the development of severe ischemic manifestations. In the current study we analyzed the implications of routine laboratory tests obtained at the time of diagnosis in the clinical spectrum of a series of 240 consecutive patients with biopsy-proven GCA at the single hospital for a defined population. We also examined whether the laboratory markers of inflammation may be predictors of severe ischemic manifestations (visual ischemic events, cerebrovascular accidents, jaw claudication, or large-artery stenosis of the extremities of recent onset), and their potential correlation. Anemia (hemoglobin <12 g/dL) was observed in 131 (54.6%) and thrombocytosis in 117 (48.8%) patients. Sixty-eight (28.3%) patients had leukocytosis. The percentage of patients showing a significant increase of alkaline phosphatase and hypoalbuminemia was similar (25% and 27.8%, respectively). The mean values of erythrocyte sedimentation rate (ESR) and C-reactive protein were 93 +/- 23 mm/h and 94 +/- 63 mg/L, respectively. A strong correlation among most laboratory markers of inflammation was observed. Anemia was more commonly observed in patients without severe ischemic manifestations (61.5% versus 48.9% in those with severe ischemic manifestation; p = 0.05) and in patients with constitutional syndrome or fever (p < 0.001). Patients with ESR greater than 100 mm/h exhibited more commonly constitutional syndrome (p < 0.001) and had a statistically significant reduction in the incidence of visual ischemic events (p < 0.025). Only 7 (22.6%) of the 31 patients who suffered permanent visual loss had an ESR at the time of disease diagnosis greater than 100 mm/h. However, in a multivariate logistic regression analysis, only anemia was found to be a negative predictor for the development of severe ischemic manifestations of GCA (odds ratio, 0.53; 95% confidence intervals, 0.30-0.94; p = 0.03). In conclusion, our results suggest that some laboratory markers of inflammation, in particular the presence of anemia, may negatively predict the risk of severe ischemic complications in GCA patients.

Vertebral fractures due to osteoporosis are a common but frequently unrecognized complication in established ankylosing spondylitis (AS). It is known that inflammatory activity in rheumatic diseases (i.e., proinflammatory cytokines) itself plays a possible role in the pathophysiology of bone loss. The aim of this study was to analyze whether inflammatory activity and an alteration of the vitamin D metabolism play a substantial role in the loss of bone mass in AS. In this cross-sectional study, 58 patients with established AS and an age- and sex-matched control group were examined. The vitamin D status was investigated, as was, in parallel, the relationship to disease activity (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), markers of bone metabolism (parathyroid hormone [PTH], 1.25 vitamin D3, 25 vitamin D3), calcium, bone alkaline phosphatase (bone-AP), urine cross-links, and plasma tumor necrosis factor alpha (TNFalpha). Bone mineral density was measured by quantitative computed tomography (QCT) of the lumbar spine. Osteoporosis was diagnosed in early as well as in progressive stages of AS (23/58=39.6%). Furthermore, serum levels of 1.25 vitamin D3 and PTH were negatively correlated with disease activity and TNFalpha. The excretion of cross-links showed a positive correlation with disease activity and TNFalpha, and 1.25 vitamin D3 and PTH were positively correlated with bone-AP. TNFalpha also positively correlated with disease activity. AS patients with osteoporosis showed significantly increased CRP, ESR, cross-links and PTH and a significantly decreased 1.25 D3. Osteoporosis is frequent in AS and high disease activity is associated with an alteration in vitamin D metabolites and increased levels of bone resorption in active AS. Our findings propose a close association of BMD, bone metabolism and inflammatory activity, possibly related to vitamin D inflammation interactions.

Peroxisome proliferator-activated receptor-gamma (PPARgamma) is a nuclear transcription factor that comprises the primary molecular target for thiazolidinedione (TZD) insulin-sensitizing drugs. Whilst expressed in many tissues in humans, its abundant expression in adipose tissue is believed to be the focal point through which TZDs regulate genes involved in glucose and lipid metabolism and via which these agents ultimately improve the hyperglycemia of type 2 diabetes. However, TZDs exhibit many additional properties, not least an array of effects which suggest a broad attack on the inflammatory process. Thus, TZDs have been shown to reduce plasma levels of the chemokine, monocyte chemotactic protein-1 (MCP-1), the anti-fibrinolytic protein, plasminogen activator inhibitor-1 (PAI-1), the endothelial cell adhesion molecules, e-selectin and inter-cellular adhesion molecule-1 (ICAM-1), the leucocyte-activating molecule, CD40L, and the tissue-remodeling enzyme, matrix metalloproteinase-9 (MMP-9). Further tangible evidence of a reduction by TZDs of systemic inflammation in patients with the classical metabolic syndrome stems from falls in the white blood cell count, P-selectin-positive platelets and in the acute-phase inflammatory proteins, C-reactive protein, serum amyloid A and fibrinogen. At the tissue level, TZDs improve vascular endothelial function, and reduce the rate of progression of intimal-medial thickening of the carotid artery and the microalbuminuria of type 2 diabetes. Further, TZDs have been shown to be efficacious in inflammatory diseases as wide-ranging as psoriasis, ulcerative colitis and non-alcoholic steatohepatitis (NASH). In the case of the latter, a broad spectrum of TZD-related properties is visible. Here, these drugs improve insulin sensitivity for glucose metabolism, reduce hyperinsulinemia, hepatic steatosis, inflammation and fibrosis, and lower the circulating levels of liver transaminases (ALT, AST), alkaline phosphatase and gamma glutamyl transferase. These effects in humans are also well-supported by investigative animal and in vitro studies. The ameliorative effects on liver fibrosis are of particular interest since they suggest that TZDs are able to activate a program of corrective tissue-remodeling. The basis for this action may be partly an ability to inhibit matrix protein secretion by hepatic stellate cells. An analogous action has also been seen in kidney mesangial cells. In conclusion, TZDs are important new drugs, presently indicated for the treatment of type 2 diabetes but with a spectrum of properties which suggests their potential for treating a number of degenerative inflammatory diseases, including NASH. However, full-scale, long-term clinical trials are needed with TZDs to test their potential to treat NASH, not least because of the (hepatotoxic) legacy of the prototype TZD, troglitazone, but also in view of the escalating burden of liver disease which is accompanying the increasing global prevalence of clinical obesity and type 2 diabetes.
