CAN | Sirolimus (SRL) is a new, potent immunosuppressive agent. More recently, proteinuria has been reported as a consequence of sirolimus therapy, although the mechanism has remained unclear. We retrospectively examined the records of 25 renal transplant patients, who developed or displayed increased proteinuria after SRL conversion. The patient cohort (14 men, 11 women) was treated with SRL as conversion therapy, due to chronic allograft nephropathy (CAN) (n = 15) neoplasia (n = 8); Kaposi's sarcoma, Four skin cancers, One intestinal tumors, One renal cell carsinom) or BK virus nephropathy (n = 2). SRL was started at a mean of 78 +/- 42 (15 to 163) months after transplantation. Mean follow-up on SRL therapy was 20 +/- 12 (6 to 43) months. Proteinuria increased from 0.445 (0 to 1.5) g/d before conversion to 3.2 g/dL (0.2 to 12) after conversion (P = 0.001). Before conversion 8 (32%) patients had no proteinuria, whereas afterwards all patients had proteinuria. In 28% of patients proteinuria remained unchanged, whereas it increased in 68% of patients. In 40% it increased by more than 100%. Twenty-eight percent of patients showed increased proteinuria to the nephrotic range. Biopsies performed in five patients revealed new pathological changes: One membranoproliferative glomerulopathy and interstitial nephritis. These patients showed persistently good graft function. Serum creatinine values did not change significantly: 1.98 +/- 0.8 mg/dL before SRL therapy and 2.53 +/- 1.9 mg/dL at last follow-up (P = .14). Five grafts were lost and the patients returned to dialysis. Five patients displayed CAN and Kaposi's sarcoma. Mean urinary protein of patients who returned to dialysis was 1.26 (0.5 to 3.5) g/d before and 4.7 (3 to 12) g/d after conversion (P = .01). Mean serum creatinine level before conversion was 2.21 mg/dL and thereafter, 4.93 mg/dL (P = .02). Heavy proteinuria was common after the use of SRL as rescue therapy for renal transplantation. Therefore, conversion should be considered for patients who have not developed advanced CAN and proteinuria. The possibility of de novo glomerular pathology under SRL treatment requires further investigation by renal biopsy. | Kidney Diseases | Disease Kidney Diseases | Pathological processes of the KIDNEY or its component tissues.

The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.

The possibility of de novo glomerular pathology under SRL treatment requires further investigation by renal biopsy. | Creatinine | Creatinine Sulfate Salt Krebiozen | MESH:D003404 | |

cyclophosphamide | In cyclophosphamide-induced cystitis in the rat, detrusor function is impaired and the expression and effects of muscarinic receptors altered. Whether or not the neuronal transmission may be affected by cystitis was presently investigated. Responses of urinary strip preparations from control and cyclophosphamide-pretreated rats to electrical field stimulation and to agonists were assessed in the absence and presence of muscarinic, adrenergic and purinergic receptor antagonists. Generally, atropine reduced contractions, but in contrast to controls, it also reduced responses to low electrical field stimulation intensity (1-5 Hz) in inflamed preparations. In both types, purinoceptor desensitization with alpha,beta-methylene adenosine-5'-triphosphate (alpha,beta-meATP) caused further reductions at low frequencies (<10 Hz). The muscarinic receptor antagonists atropine, 4-diphenylacetoxy-N-methylpiperidine (4-DAMP) ('M(1)/M(3)/M(5)-selective'), methoctramine ('M(2)-selective') and pirenzepine ('M(1)-selective') antagonized the tonic component of the electrical field stimulation-evoked contractile response more potently than the phasic component. 4-DAMP inhibited the tonic contractions in controls more potently than methoctramine and pirenzepine. In inflamed preparations, the muscarinic receptor antagonism on the phasic component of the electrical field stimulation-evoked contraction was decreased and the pirenzepine and 4-DAMP antagonism on the tonic component was much less efficient than in controls. In contrast to controls, methoctramine increased -- instead of decreased -- the tonic responses at high frequencies. While contractions to carbachol and ATP were the same in inflamed and in control strips when related to a reference potassium response, isoprenaline-induced relaxations were smaller in inflamed strips. Thus, in cystitis substantial changes of the efferent functional responses occur. While postjunctional beta-adrenoceptor-mediated relaxations are reduced, effects by prejunctional inhibitory muscarinic receptors may be increased. | Cyclophosphamide | Anhydrous Cyclophosphamide B 518 B-518 B518 Monohydrate (R)-Isomer (S)-Isomer Cyclophosphane Cytophosphan Cytophosphane Cytoxan Endoxan NSC 26271 NSC-26271 NSC26271 Neosar Procytox Sendoxan | Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide.

benzodiazepines | OBJECTIVE: To describe associations between the use of benzodiazepines or related drugs (BZDs/RDs) and health, functional abilities and cognitive function in the elderly. METHODS: A non-randomised clinical study of patients aged > or =65 years admitted to acute hospital wards during 1 month. 164 patients (mean age +/- standard deviation [SD] 81.6 +/- 6.8 years) were admitted. Of these, nearly half (n = 78) had used BZDs/RDs before admission, and the remainder (n = 86) were non-users. Cognitive ability was assessed by the Mini-Mental State Examination (MMSE). Patients scoring > or =20 MMSE sum points were interviewed (n = 79) and questioned regarding symptoms and functional abilities during the week prior to admission. Data on use of BZDs/RDs before admission, current medications and discharge diagnoses were collected from medical records. Health, physical abilities and cognitive function were compared between BZD/RD users and non-users, and adjustments were made for confounding variables. The residual serum concentrations of oxazepam, temazepam and zopiclone were analysed. RESULTS: The mean +/- SD duration of BZD/RD use was 7 +/- 7 years (range 1-31). Two or three BZDs/RDs were concomitantly taken by 26% of users (n = 20). Long-term use of these drugs was associated with female sex and use of a higher number of drugs with effects on the CNS, which tended to be related to diagnosed dementia. After adjustment for these variables as confounders, use of BZDs/RDs was not associated with cognitive function as measured by the MMSE. However, use of BZDs/RDs was associated with dizziness, inability to sleep after awaking at night and tiredness in the mornings during the week prior to admission and with stronger depressive symptoms measured at the beginning of the hospital stay. Use of BZDs/RDs tended to be associated with a reduced ability to walk and shorter night-time sleep during the week prior to admission. A higher residual serum concentration of temazepam correlated with a lower MMSE sum score after adjustment for confounding variables. CONCLUSIONS: Long-term use and concomitant use of more than one BZD/RD were common in elderly patients hospitalised because of acute illnesses. Long-term use was associated with daytime and night-time symptoms indicative of poorer health and potentially caused by the adverse effects of these drugs. | Benzodiazepines | Benzodiazepine Compounds Benzodiazepines | A group of two-ring heterocyclic compounds consisting of a benzene ring fused to a diazepine ring.

A 49-year-old woman was transferred to our department because of quadriparesis, lancinating pain, sensory loss, and paresthesia of the distal limbs. One month previously, she had taken a single high dose of disulfiram (130 tablets of ALCOHOL STOP TAB, Shin-Poong Pharm. Co., Ansan, Korea) in a suicide attempt. She was not an alcoholic. For the first few days after ingestion, she was in a confused state and had mild to moderate ataxia and giddiness. She noticed hoarseness and distally accentuated motor and sensory dysfunction after she had recovered from this state. A nerve conduction study was consistent with severe sensorimotor axonal polyneuropathy. Laryngeal electromyography (thyroarytenoid muscle) showed ample denervation potentials. Laryngoscopy revealed asymmetric vocal fold movements during phonation. Her vocal change and weakness began to improve spontaneously about 3 weeks after transfer.

quadriparesis | Acute peripheral neuropathy caused by a disulfiram overdose is very rare and there is no report of it leading to vocal fold palsy. A 49-year-old woman was transferred to our department because of quadriparesis, lancinating pain, sensory loss, and paresthesia of the distal limbs. One month previously, she had taken a single high dose of disulfiram (130 tablets of ALCOHOL STOP TAB, Shin-Poong Pharm. Co., Ansan, Korea) in a suicide attempt. She was not an alcoholic. For the first few days after ingestion, she was in a confused state and had mild to moderate ataxia and giddiness. She noticed hoarseness and distally accentuated motor and sensory dysfunction after she had recovered from this state. A nerve conduction study was consistent with severe sensorimotor axonal polyneuropathy. Laryngeal electromyography (thyroarytenoid muscle) showed ample denervation potentials. Laryngoscopy revealed asymmetric vocal fold movements during phonation. Her vocal change and weakness began to improve spontaneously about 3 weeks after transfer. This was a case of acute palsy of the recurrent laryngeal nerve and superimposed severe acute sensorimotor axonal polyneuropathy caused by high-dose disulfiram intoxication. | Quadriplegia | Flaccid Quadriplegia Quadriplegias Tetraplegia Tetraplegias Locked In Syndrome Locked-In Syndromes Paralysis Spinal Quadriplegic Quadripareses Quadriparesis Spastic | Severe or complete loss of motor function in all four limbs which may result from BRAIN DISEASES; SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; or rarely MUSCULAR DISEASES.

heparin | OBJECTIVES: To correlate optical density and percent inhibition of a two-step heparin-induced thrombocytopenia (HIT) antigen assay with thrombosis; the assay utilizes reaction inhibition characteristics of a high heparin concentration. PATIENTS AND METHODS: Patients with more than 50% decrease in platelet count or thrombocytopenia (<150 x 10(9)/L) after exposure to heparin, who had a positive two-step antigen assay [optical density (OD) >0.4 and >50 inhibition with high concentration of heparin] were included in the study. RESULTS: Forty of 94 HIT patients had thrombosis at diagnosis; 54/94 had isolated-HIT without thrombosis. Eight of the isolated-HIT patients developed thrombosis within the next 30 d; thus, a total of 48 patients had thrombosis at day 30. At diagnosis there was no significant difference in OD between HIT patients with thrombosis and those with isolated-HIT. However, OD was significantly higher in all patients with thrombosis (n = 48, 1.34 +/- 0.89), including isolated-HIT patients who later developed thrombosis within 30 d (n = 8, 1.84 +/- 0.64) as compared to isolated-HIT patients who did not develop thrombosis (0.96 +/- 0.75; P = 0.011 and P = 0.008). The Receiver Operative Characteristic Curve showed that OD >1.27 in the isolated-HIT group had a significantly higher chance of developing thrombosis by day 30. None of these groups showed significant difference in percent inhibition. Multivariate analysis showed a 2.8-fold increased risk of thrombosis in females. Similarly, thrombotic risk increased with age and OD values. CONCLUSION: Higher OD is associated with significant risk of subsequent thrombosis in patients with isolated-HIT; percent inhibition, however, was not predictive. | Heparin | Heparin Sodium Unfractionated Heparinic Acid Liquaemin alpha alpha-Heparin | A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges.

Moreover, a positive correlation of histamine to gastric hemorrhage and to ulcer was found in those atherosclerotic rats. This hemorrhagic ulcer and various ulcerogenic parameters were dose-dependently ameliorated by daily intragastric verapamil. Atherosclerosis could produce gastric hemorrhagic ulcer via aggravation of gastric acid back-diffusion, LPO generation, histamine release and microvascular permeability that could be ameliorated by verapamil in rats. | Atherosclerosis | Atherogenesis Atheroscleroses Atherosclerosis | A thickening and loss of elasticity of the walls of ARTERIES that occurs with formation of ATHEROSCLEROTIC PLAQUES within the ARTERIAL INTIMA.

gastric hemorrhagic | Studies concerning with pathogenesis of gastric hemorrhage and mucosal ulceration produced in atherosclerotic rats are lacking. The aim of this study is to examine the role of gastric acid back-diffusion, mast cell histamine release, lipid peroxide (LPO) generation and mucosal microvascular permeability in modulating gastric hemorrhage and ulcer in rats with atherosclerosis induced by coadministration of vitamin D2 and cholesterol. Additionally, the protective effect of verapamil on this ulcer model was evaluated. Male Wistar rats were challenged intragastrically once daily for 9 days with 1.0 ml/kg of corn oil containing vitamin D2 and cholesterol to induce atherosclerosis. Control rats received corn oil only. After gastric surgery, rat stomachs were irrigated for 3 h with either simulated gastric juice or normal saline. Gastric acid back-diffusion, mucosal LPO generation, histamine concentration, microvascular permeability, luminal hemoglobin content and ulcer areas were determined. Elevated atherosclerotic parameters, such as serum calcium, total cholesterol and low-density lipoprotein concentration were obtained in atherosclerotic rats. Severe gastric ulcers accompanied with increased ulcerogenic factors, including gastric acid back-diffusion, histamine release, LPO generation and luminal hemoglobin content were also observed in these rats.

heart failure | Adriamycin-induced autophagic cardiomyocyte death plays a pathogenic role in a rat model of heart failure. | Heart Failure | Cardiac Failure Congestive Heart Decompensation Left Sided Left-Sided Right Right-Sided Myocardial | A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

heart failure | BACKGROUND: The mechanisms underlying heart failure induced by adriamycin are very complicated and still unclear. The aim of this study was to investigate whether autophagy was involved in the progression of heart failure induced by adriamycin, so that we can develop a novel treatment strategy for heart failure. METHODS: 3-methyladenine (3MA), a specific inhibitor on autophagy was used in a heart failure model of rats induced by adriamycin. Neonatal cardiomyocytes were isolated from Sprague-Dawley rat hearts and randomly divided into controls, an adriamycin-treated group, and a 3MA plus adriamycin-treated group. We then examined the morphology, expression of beclin 1 gene, mitochondrial permeability transition (MPT), and Na+-K+ ATPase activity in vivo. We also assessed cell viability, mitochondrial membrane potential changes and counted autophagic vacuoles in cultured cardiomyocytes. In addition, we analyzed the expression of autophagy associated gene, beclin 1 using RT-PCR and Western blotting in an animal model. RESULTS: 3MA significantly improved cardiac function and reduced mitochondrial injury. Furthermore, adriamycin induced the formation of autophagic vacuoles, and 3MA strongly downregulated the expression of beclin 1 in adriamycin-induced failing heart and inhibited the formation of autophagic vacuoles. CONCLUSION: Autophagic cardiomyocyte death plays an important role in the pathogenesis of heart failure in rats induced by adriamycin. Mitochondrial injury may be involved in the progression of heart failure caused by adriamycin via the autophagy pathway. | Heart Failure | Cardiac Failure Congestive Heart Decompensation Left Sided Left-Sided Right Right-Sided Myocardial | A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body.
