Various forms of chemically induced liver injury and their detection by diagnostic procedures. (1/534)

A large number of chemical agents, administered for therapeutic or diagnostic purposes, can produce various types of hepatic injury by several mechanisms. Some agents are intrinsically hepatotoxic, and others produce hepatic injury only in the rare, uniquely susceptible individual. Idiosyncrasy of the host is the mechanism for most types of drug-induced hepatic injury. It may reflect allergy to the drug or a metabolic aberation of the host permitting the accumulation of hepatotoxic metabolites. The syndromes of hepatic disease produced by drugs have been classified hepatocellular, hepatocanalicular, mixed and canalicular. Measurement of serum enzyme activities has provided a powerful tool for studies of hepatotoxicity. Their measurement requires awareness of relative specificity, knowledge of the mechanisms involved, and knowledge of the relationship between known hepatotoxic states and elevated enzyme activities.  (+info)

Comparison of a parasite lactate dehydrogenase-based immunochromatographic antigen detection assay (OptiMAL) with microscopy for the detection of malaria parasites in human blood samples. (2/534)

Microscopic examination of blood smears remains the gold standard for malaria diagnosis, but is labor-intensive and requires skilled operators. Rapid dipstick technology provides a potential alternative. A study was conducted in The Gambia to compare the performance of OptiMAL, an immunochromatographic antigen detection assay for the diagnosis of malaria using parasite lactate dehydrogenase, against standard microscopy in patients with suspected malaria. For initial diagnosis of Plasmodium falciparum, irrespective of stage, this assay had a sensitivity of 91.3%, a specificity of 92%, a positive predictive value of 87.2%, and a negative predictive value of 94.7%. The sensitivity of the test decreased markedly at parasitemias < 0.01%. This assay can be used for the diagnosis of malaria in areas where microscopy is not available and for urgent malaria diagnosis at night and at weekends, when routine laboratories are closed and when relatively inexperienced microscopists may be on duty.  (+info)

Underestimation of acute pancreatitis: patients with only a small increase in amylase/lipase levels can also have or develop severe acute pancreatitis. (3/534)

BACKGROUND: In most treatment studies on acute pancreatitis, pancreatologists base their diagnosis on amylase/lipase levels more than three times above the upper limit of normal (>3n) and thus exclude patients with smaller enzyme level increases. The recommendations derived from the results of treatment studies do not take into account such patients. Non-pancreatologists frequently believe that only patients with high enzyme levels have a serious prognosis. AIMS: To question the assumption that high enzyme levels indicate severe, and conversely low enzyme levels indicate mild, acute pancreatitis. PATIENTS/METHODS: This retrospective study includes 284 consecutive patients with a first attack of acute pancreatitis. The cause was biliary in 114 (40%) patients, alcoholism in 83 (29%), other in 21 (7%), and unknown in 66 (23%). Patients were divided into two groups according to their serum enzyme levels (amylase: 3n, n = 196; lipase: 3n, n = 233). Renal impairment, indication for dialysis and artificial ventilation, development of pseudocysts, necessity for surgery, and mortality were taken as parameters of severity. RESULTS: The incidence of severity was the same for both the 3n groups. CONCLUSIONS: The severity of acute pancreatitis is independent of the elevation in serum amylase/lipase level (3n) on admission. Patients with only a slight increase can also have or develop severe acute pancreatitis. Patients with +info)

Myocardial infarction in a pre-menopausal woman with angiographically normal coronary arteries. (4/534)

A young pre-menopausal non-drug-addict woman without risk factors for coronary artery disease suffered from a non-Q-wave acute myocardial infarction. She presented with epigastric pain and vomiting. Diagnosis of acute myocardial infarction was not suspected at first because of her young age and lack of risk factors. She was treated for gastritis but worsening of epigastric pain and its radiation to chest warranted the diagnosis of acute myocardial infarction, which was confirmed by serial serum cardiac enzymes. Subsequent coronary angiogram revealed normal coronary arteries.  (+info)

In situ zymographic localisation of type II collagen degrading activity in osteoarthritic human articular cartilage. (5/534)

OBJECTIVES: Chondrocytic matrix metalloproteinases (MMPs) are believed to be important in osteoarthritic cartilage degradation. The cartilage lesion of osteoarthritis (OA) is focal and often progressive. During its development chondrocytes differentially up and down regulate production of mRNA for individual MMPs. This observation has potential implications for understanding the disease processes that lead to progressive cartilage loss in OA and designing appropriate targeted treatment. The complex regulation of MMP mediated effects means there is a pressing need to establish whether visualisation of MMP mRNA or protein equates to enzyme activity. The technique of in situ zymography (ISZ) offers a way of examining diseased human tissue for in vivo production of an excess of degrading enzyme over inhibitor. The primary objective of this study was to assess, and if positive follow, collagen II degrading activity in cartilage during development of the OA lesion. A secondary objective was to assess whether there was any correlation between sites of collagen II degrading activity and expression of the collagenase (MMP-13), recently implicated in type II collagen degredation in this lesion. METHODS: Biopsied human normal and osteoarthritic cartilage, showing various degrees of damage, was examined by in situ zymography, with and without enzyme inhibitors, to establish sites of type II collagenase activity. Paired samples were probed for MMP-13 mRNA using 35S-labelled oligonucleotide probes. Comparative analyses were performed. RESULTS: In situ zymography showed collagen II degrading activity over chondrocytes only in osteoarthritic cartilage. Distribution and amount varied with the extent of cartilage damage and position of chondrocytes, being greatest in deep cartilage and in cartilage lesions where fissuring was occurring. The enzyme causing the degradation behaved as a matrix metalloproteinase. MMP-13 mRNA expression codistributed with the type II collagenase activity. CONCLUSION: In OA, chondrocytes can degrade type II collagen. The type II collagen degrading activity varies in site and amount as the cartilage lesion progresses and throughout codistributes with MMP-13 mRNA expression.  (+info)

Ruling out acute myocardial infarction early with two serial creatine kinase-MBmass determinations. (6/534)

AIMS: We studied the diagnostic value for acute myocardial infarction of serial creatine kinase-MBmass measurements on admission and at 7 h after the onset of symptoms. METHODS AND RESULTS: Patients presenting to our chest pain unit with symptoms of <5-h duration were eligible. Patients were kept under observation at least until 12 h after onset of symptoms. Blood samples were drawn on admission and 7 and 10 h after onset of symptoms. Creatine kinase-MBmass>7.0 microg x 1(-1) (upper reference limit for acute myocardial infarction), or an increase >2.0 microg x 1(-1) (reference change value) between admission and at 7 h was considered abnormal. Of a total of 470 patients, 248 patients had acute myocardial infarction: 100 out of the 248 patients had a single creatine kinase-MBmass>7.0 microg x 1(-1) on admission (sensitivity 40%, 95% CI:34-46%), 234/248 patients at 7 h (sensitivity 94%, 95% CI:91-97%), and 240/248 at 10 h (sensitivity 97%, 95% CI:94-99%). At 7 h, 246/248 patients had either a single creatine kinase-MB >7.0 microg x 1(-1) or a significant increase between admission and 7 h (sensitivity 99%, 95% CI:98-100%). Of 222 patients without acute myocardial infarction, 214 had a normal serial creatine kinase-MBmass (specificity 96%, 95% CI:93-98%). CONCLUSION: In patients with symptoms of <5-h duration, acute myocardial infarction can be ruled out using serial creatine kinase-MBmass taken on admission and at 7 h.  (+info)

Examination of synovial fluid and serum hyaluronidase activity as a joint marker in rheumatoid arthritis and osteoarthritis patients (by zymography). (7/534)

OBJECTIVE: Hyaluronic acid (HA) is an important joint marker and the substrate for hyaluronidase (HAase). Synovial fluid (SF) and serum HAase were measured to investigate the potential use of HAase as a joint marker in rheumatoid arthritis (RA) and osteoarthritis (OA) patients. METHODS: The subjects were 39 patients with RA and 42 patients with OA. HAase activity was measured by zymography and its relation with various parameters examined statistically. RESULTS: In RA SF a positive correlation (r = 0.458, p = 0.0186) was found between SF HAase activity and the concentration of serum C reactive protein. A positive correlation (r = 0.45, p = 0.024) was also found between SF HAase activity and platelet count in the RA group. Serum HAase activity in the RA group was significantly higher than in the OA group (p < 0.0001) and normal controls (p < 0.0001). CONCLUSION: The results suggest that SF HAase activity could be used as a marker of synovial inflammation.  (+info)

Biochemical evidence of thiamin deficiency in young Ghanian children. (8/534)

Detailed biochemical studies for nutritional status were carried out on 146 Ghanaian children ages 6 months to 6 years over a 2-year period. Study children comprised three main groups: severe protein-calorie malnutrition; mild to moderate protein-calorie malnutrition and apparently healthy children. Erythrocyte transketolase activity and the percentage of erythrocyte transketolase pyrophosphate effect were also determined. In the first year of the study elevated percentage of transketolase pyrophosphate effect indicative of thiamin deficiency was found in all three of the above-mentioned groups, with the most widespread deficiency in the normal groups. In year 2, repeat studies of the severely malnourished group after 2 weeks of nutritional therapy with the administration of vitamin capsules, which included thiamin, resulted in the normalization of transketolase pyrophosphate effect. Apoenzyme activity was comparable in all groups studied. There were no obvious clinical signs of thiamin deficiency, although sensory testing was not performed. A relatively large number of children with high percentage of transketolase pyrosphosphate effect also had serum folic acid deficiency. This evidence of widespread biochemical thiamin deficiency is indicative of an at-risk population among young children for clinical thiamin deficiency. Further studies are needed to identify whether the problem is inadequate thiamin intake, destruction of thiamin by thiaminases or food preparation methods, or malabsorption of thiamin.  (+info)

The U.S. Food and Drug Administration today announced that monthly liver enzyme tests are no longer required for those taking Letairis tablets (ambrisentan), used to treat high blood pressure in the vessels that carry blood to the lungs (pulmonary arterial hypertension, or PAH).. Citing data from clinical trials and postmarket reports, the FDA said that the drug poses only a low risk of liver injury. Information related to potential serious liver injury and the need to monitor for such serious injury is being removed from the drugs boxed warning.. In patients with PAH, Letairis slows the worsening of symptoms and improves the ability to exercise. Approved in 2007, Letairis is in a class of medications called endothelin receptor antagonists, which stop the action of endothelin, a substance that narrows blood vessels and prevents normal blood flow in those with PAH. We have concluded that monthly liver enzyme testing for patients taking Letairis, as previously noted in the boxed warning, is not ...

All patients treated with CRESTOR should be advised to promptly report any symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine, or jaundice. There have been rare post-marketing reports of fatal and non-fatal hepatic failure in patients taking statins, including CRESTOR. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with CRESTOR, promptly interrupt therapy. If an alternate etiology is not found, do not restart ...
My husband had a 4mm melanoma removed from his back in Nov. 12 using the wide excision.

His liver enzyme test was high so they took him oiff of cholesterol meds and told him to quit naproxen as that would affect results. Last test it had gone down slightly.
Deoxycytidylate (DCMP) deaminase was assayed at various times during and after normal and abnormal pregnancies. The level in amniotic fluid was assessed at induction and at caesarean section, and cord blood levels were estimated after normal delivery and at caesarean section. A rise occurred during labour and after hysterectomy and caesarean section--returning to normal after 2-3, and 12 days respectively. Levels above 4.8 X 10-minus 4 ml-minus 1 were found in cases of preeclamptic toxaemia and early intrauterine death and in twin pregnancies over 36 weeks gestation. It is suggested that because of its low incidence of false-negative and false-positive results this test is far superior to other enzyme tests in pregnancy, and a further trial is in progress to assess its role. ...

Introduction: Potential hepatotoxicity associated with disease modifying anti-rheumatic drugs [DMARDs] requires laboratory monitoring. In rheumatoid and psoriatic arthritis [RA, PsA] patients, we examined the incidence of elevated alanine/aspartate aminotransferase (ALT/AST) enzymes associated with methotrexate (MTX), leflunomide (LEF), and MTX+LEF vs. other DMARDs.. Methods: RA and PsA patients enrolled in the Consortium of Rheumatology Researchers of North America (CORRONA) initiating DMARDs were identified. Abnormalities were identified when either was 1 or 2-fold time above the upper limits of normal (ULN). Odds ratios [OR] between MTX/LEF dose and elevated ALT/AST enzymes were estimated using generalized estimating equations. Interaction terms for use of MTX+LEF quantified the incremental risk of the combination compared to each individually.. Results: Elevated ALT/AST levels (,1x ULN) occurred in 22, 17, 31, and 14% RA patients receiving MTX, LEF, MTX+LEF, or neither, respectively; ...

Some tests look for enzymes produced by prostate cancer to assess whether the condition is present, and whether it may be aggressive or fast growing. These tests use either blood or urine samples to assess a mans risk.. Doctors normally recommend these tests for men who have high PSA scores or whose doctors find abnormalities during a digital prostate exam. One new blood test is the 4Kscore test, which measures a mans risk of prostate cancer. This test does not replace a biopsy, but it can help identify which men should have one. As a result, it may help reduce the total number of men who undergo biopsies. Enzyme tests cannot identify every case of prostate cancer but neither can biopsies. Instead, blood and urine screenings find the most aggressive cases of the disease.. Some forms of prostate cancer are slow-growing rather than aggressive. These forms are unlikely to be fatal. ...

CK is a dimeric enzyme. There are two common gene products, one coding for the subunit (so named because of its predominance in muscle) and the other for the B subunit (so named because of its predominance in brain tissue). The three common forms of active CK include two homodimers and one heterodimer. The first homodimer (CK-1) consists of two B subunits and is referred to as CKBB. The other has two M subunits and is referred to as CKMM (CK-3). The heterodimer has one of each subunit and is referred to as CKMB (CK-2)2. The specificity of CKMB for cardiac tissue is what has made it such a powerful diagnostic tool for the diagnosis of acute myocardial infarction (AMI). There is a third gene product which results in the mitochondrial form of CK.. Along with CKMB, significant levels of CKMM activity are found in cardiac muscle and therefore a large increase in total CK was once used as a tool in the diagnosis of AMI3. Once the CK isoenzymes were elucidated and isoenzyme tests became available, CKMB ...

Total lactate dehydrogenase (LDH; EC activity and the percentage distribution of LDH isoenzymes were determined in 127 patients with malignant diseases. A shift in the isoenzyme patterns was observed toward the M-type, with an increase in the percentage of LDH-4 and LDH-5 isoenzymes and a slight increase in total LDH activity of all patients. Serum samples from 68 of the patients contained an abnormal isoenzyme of LDH, LDH-1 ex, that, on agarose gel electrophoresis at pH 8.6, migrated between albumin and LDH-1 isoenzyme. Chemotherapy, radiotherapy, or surgical removal of the tumor was accompanied by disappearance of this abnormal isoenzyme. The heat stability of LDH-1 ex isoenzyme appears to be similar to that of LDH-1 but greater than that of the other LDH isoenzymes.

Temporal changes in serum creatine kinase concentration and degree of muscle rigidity in 24 patients with neuroleptic malignant syndrome Koichi Nisijima, Katutoshi ShiodaDepartment of Psychiatry, Jichi Medical University, Tochigi, JapanAbstract: Neuroleptic malignant syndrome (NMS) is a dangerous adverse response to antipsychotic drugs. It is characterized by the four major clinical symptoms of hyperthermia, severe muscle rigidity, autonomic dysfunction, and altered mental state. Serum creatine kinase (CK) elevation occurs in over 90% of NMS cases. In the present study, the detailed temporal changes in serum CK and degree of muscle rigidity, and the relationship between CK concentration and degree of muscle rigidity over the time course from fever onset, were evaluated in 24 affected patients. The results showed that serum CK peaked on day 2 after onset of fever and returned to within normal limits at day 12. Mild muscle rigidity was observed before the onset of fever in 17 of 24 cases (71%). Muscle
In a multicenter double-blind study, 227 patients with suspected acute myocardial infarction (AMI) were randomized within 12 hr from onset of symptoms to treatment with nifedipine (112 patients) or placebo (115 patients). AMI was confirmed in 74 patients on nifedipine and in 83 on placebo. Patients with AMI received nifedipine 5.5 +/- 2.9 hr (mean +/- SD) after onset of symptoms. Infarct size was assessed by the release of creatine kinase isoenzyme MB (CK-MB). Infarct size index (CK-MB geq/m2) was 25 +/- 16 (n = 71) in the nifedipine group and 23 +/- 13 (n = 77) in the placebo group (NS). After the first 10 mg of nifedipine systolic blood pressure fell from 147 +/- 30 to 135 +/- 28 mm Hg (p less than .01) and heart rate rose from 75 +/- 18 to 79 +/- 19 beats/min (p less than .01). No change was observed after the first placebo dose. The treatment was continued for 6 weeks. Over this period there were 10 deaths in each group. Early treatment with nifedipine in patients with AMI does not seem to ...

N2 - MB Leak patients who develop an elevated MB relative index with a normal total creatine kinase (CK) level are not as well characterized as those who have diagnostic enzyme elevations in the setting of ST elevation (↑) or non-ST↑ acute myocardial infarction (AMI). During a 1-year period, we studied all patients hospitalized in an urban academic hospital with suspected AMI who developed an elevated MB relative index within 24 hours of presentation. Of 595 patients, 44% had MB Leak, 34% had non-ST↑ AMI and 22% had ST↑ AMI. Patients with MB Leak and non-ST↑ AMI were significantly older than those with ST↑ AMI (mean ages 69, 71, and 63 years, ...
My daughter is 34... Beginning in high school she became troubled somewhat by IBS and it continued in a mild (it is relative) form until 2006 or so. At that point she became miserable, soon lost her job and socially unsecure.. We tried all of the gastroenterologists in two major hospital groups, endocrinologists and local medical schools. Allergy testing, scoping, swallowing cameras, bacteria tests, enzyme tests, testing to all susceptibilities - including gluten. We tried eliminating fat and many other items too.. But through all of this the doctors told her that she didnt have an issue with dairy or gluten. Her suffering continued.... Six weeks ago, her mother finally suggested that she give up gluten and dairy at the same time.. What a difference that has made! She can actually sit at the table and finish a meal without running... her outlook is positive again.. So, I wanted just to share this encouragement and say that sometimes, doctors dont have all of the answers, and it may be a good ...
Following acute myocardial infarction, CK-MB activity increases significantly and this elevation is highly specific for the laboratory diagnosis of myocardial infarction. Although total CK activity usually increases following myocardial infarction, in some patients only the CK-MB activity increases, while the total CK remains in the normal range. In this procedure CK activity is measured in the presence of an antibody to CK-M monomer. This antibody completely inhibits the activity of CK-MM and half of the activity of CK-MB, while not affecting the B subunit activity of CK-MB and CK-BB. Due to negligible concentrations of CK-BB in the circulation, the remaining activity, multiplied by a factor of 2, represents the activity of the CK-MB isoenzyme ...
