Cocaine not only is an arterial vasoconstrictor but also may contribute to arterial thrombosis by activating platelets and increasing their aggregability diabete oms generic actoplus met 500 mg on line, enhancing thromboxane production diabetes type 1 normal blood sugar discount actoplus met 500mg amex, and inducing endothelial cell injury diabetes diet handout spanish purchase actoplus met line. Isolated case reports have attributed a wide variety of glomerular and tubulointerstitial renal diseases to cocaine use diabetes type 2 jewelry order 500 mg actoplus met. Cocaine use has been associated with antiglomerular basement membrane disease diabetic diet using exchanges proven actoplus met 500mg, acute interstitial nephritis epilepsy and diabetes in dogs purchase genuine actoplus met on-line, hyponatremia, and systemic necrotizing vasculitis (Alfaro et al. However, a causal relationship between cocaine use and many of these disorders remains to be established. Chronic administration of cocaine to rats induces glomerulosclerosis and chronic tubulointerstitial injury including tubular dilation and necrosis of tubular cells (Barroso-Moguel et al. In vitro studies of renal tissue indicate that cocaine enhances mesangial cell uptake of macromolecules, increases the release of macrophage secretory products and cytokines that stimulate mesangial cell proliferation, and is cytotoxic to proximal tubular epithelial cells (Mattana et al. Cocaine also increases cellular oxidative stress and decreases intracellular glutathione levels in renal epithelial cells (Palamara et al. However, the relationship of these experimental observations to human disease remains to be established. However, this relationship has not always been supported by epidemiological studies. These investigators concluded that cocaine use may cause an acute elevation in blood pressure but was not associated with chronic hypertension. There was no significant difference in age-adjusted blood pressure in the population of cocaine users as compared to a control group. In addition, microalbuminuria was not detected in patients who had used cocaine for a mean of 12 years. Accelerated atherosclerosis of the renal vasculature has been attributed to cocaine use even in the absence of hypertension (Di Paolo et al. Cocaine addicts not only showed extensive atherosclerosis with medial thickening, luminal narrowing, and vessel obstruction but also showed more glomerular hyalinosis, periglomerular fibrosis, and interstitial cellular infiltration as compared to controls. The pathogenesis of accelerated hyperplastic atherosclerotic damage in cocaine addicts is unclear. Cocaine use may also accelerate atherosclerosis by inducing mononuclear cell infiltration of atherosclerotic plaques and by increasing the permeability of the vascular endothelium to diffusion of atherogenic lipoproteins. Numerous congenital renal abnormalities have been associated with maternal cocaine use including hydronephrosis, horseshoe kidney, prune belly syndrome, renal agenesis, prominent renal pelvis, nephromegaly, unilateral small kidney, and genital abnormalities (Battin et al. Urine output is frequently reduced in fetuses exposed to cocaine (Mitra, 1999; Mitra et al. Prenatal cocaine exposure has also been associated with an increased incidence of urinary tract infections (Gottbrath-Flaherty et al. Stillborn fetuses exposed to cocaine in utero may show thickening of the renal interlobular artery walls with luminal narrowing and multivessel intimal-type fibromuscular dysplasia (Mitra et al. Vascular abnormalities are associated with elevated renal artery resistive indices (Mizutani et al. Prenatal exposure to cocaine has also been associated with persistent postnatal hypertension and, in particular, severe hypertension secondary to renal artery stenosis (Ho et al. Renovascular disease and congenital urinary tract abnormalities are also seen in experimental models of in utero cocaine exposure (Finnell et al. Proposed mechanisms for these developmental abnormalities include cocaine-induced vasoconstriction of uterine and fetal blood vessels and cocaine-induced alterations in calcium metabolism. Persistent postnatal hypertension in the absence of renal developmental abnormalities has been attributed to cocaine-induced sympathetic nervous system dysfunction (Horn, 1992). Although a wide variety of drugs were involved, methamphetamine was used in nearly all reported cases and was used exclusively in one case. However, in recent years, the existence of a distinct clinical syndrome of systemic necrotizing vasculitis in amphetamine users has been questioned. Vasculitis may have been due to unrecognized infection with hepatitis B or hepatitis C virus. Levamisole not only is used as a cutting and bulking agent but also potentiates the psychotropic effects of cocaine. It also possesses immunomodulatory properties that induce the loss of tolerance to numerous autoantigens. Detection of levamisole in the urine may be problematic due to its short half-life of 5. Pauci-immune complex necrotizing and crescentic glomerulonephritis and leukocytoclastic angiitis involving the skin were documented. Antimyeloperoxidase antibodies were present in the serum of all cases, and 50% also showed antiprotease 3 antibodies. To circumvent Federal regulation, these agents are sold as plant food, fertilizer, incense, bath additives or insect repellent and labeled as not intended for human consumption. Many of these compounds are not detected by routine urine drug screening and have been associated with a broad spectrum of renal complications (Luciano and Perazella, 2014; Pendergraft et al. The compound may be administered by various routes and can be ingested, smoked, injected, or inhaled. This occurs predominantly in young women in an idiosyncratic, nondose-dependent manner, often in first-time users. In addition, increased thirst and dry mouth lead to excessive free water ingestion and contribute to the development of dilutional hyponatremia. Synthetic cannabinoids bind to the cannabis receptors and exert cannabis-like psychoactive effects. They are marketed as "Spice," "K2," "Spice Gold," or "Kronic," combined with herbal mixtures in the form of incense, bath additives, or air fresheners. Although prerenal azotemia due to volume depletion may occur, most cases show no hemodynamic compromise and only modest elevations of creatine phosphokinase enzyme levels, suggesting a direct nephrotoxic effect. Biopsy of the kidney has demonstrated acute tubular necrosis or less commonly acute interstitial nephritis. The primary mechanism of action of mephedrone is stimulation of dopamine release and inhibition of reuptake through interactions with the dopamine transporter. These compounds are marketed in capsule, pill, or powder form as plant food, fertilizer, bath salts, or insect repellents not suitable for human consumption and are commonly referred to as "bath salts. A number of renal complications have been associated with the use of these agents (Alansari and Hamilton, 2006; Berney-Meyer et al. Their use has been linked to acute tubular necrosis in the presence or absence of rhabdomyolysis associated with hyperthermia and seizures. Isolated case reports describe immune complex-mediated glomerulonephritis, interstitial nephritis, urinary retention, and hyponatremia associated with their use. These compounds are marketed as "Solaris," "Smiles," "N bomb," and "Cimbi-5" in the form of capsules, powder, or liquid preparations. Chronic abuse of ketamine has been associated with a wide variety of urological disorders including decreased bladder capacity, bladder wall thickening, papillary necrosis, renal infarction, ureteral strictures, hydronephrosis, dysuria, urinary frequency, suprapubic pain, microscopic or gross hematuria, and renal functional impairment (Chen et al. Death") increases release of serotonin and, to a lesser degree dopamine, from presynaptic neurons. Clinical manifestations include renal functional impairment, proteinuria, and nephrotic syndrome. Renal biopsies haves demonstrated focal and segmental glomerulosclerosis with perihilar lesions suggestive of hyperfiltration injury or, less commonly, collapsing glomerular lesions. Nonanion gap hyperchloremic metabolic acidosis attributed to toluene sniffing was first described by Taher et al. A distal renal tubular acidosis was suggested by the finding of a high urinary pH and urinary bicarbonate wasting. Renal tubular acidosis rapidly resolved after discontinuation of toluene abuse but recurred with repeated episodes of toluene exposure. Hypokalemia, resulting from renal potassium wasting due to secondary hyperaldosteronism, was a characteristic feature, which in turn led to generalized muscle weakness or even flaccid quadriparesis. Numerous additional cases of hyperchloremic metabolic acidosis due to toluene abuse have subsequently been reported. Maternal toluene abuse has been reported to give rise to transient Nephrotoxicity of Lithium and Drugs of Abuse 327 congenital renal tubular dysfunction with hyperchloremic metabolic acidosis (Erramouspe et al. Patients frequently presented with muscle weakness, which in some cases progressed to quadriparesis. Muscle symptoms were attributed in most cases to nontraumatic rhabdomyolysis due to hypokalemia and/or hypophosphatemia. However, rhabdomyolysis also occurred in the absence of these electrolyte disturbances, suggesting that toluene may have direct toxic effects on skeletal muscle. Although serum calcium levels were normal on presentation, calcium levels frequently declined during fluid repletion and led to symptomatic hypocalcemia in some patients. Tolueneabusers were unable to acidify the urine despite normal urinary bicarbonate reabsorption. Hydrogen ion back diffusion was excluded as a factor in the genesis of the acidification defect. Toluene reduced the rate of proton secretion in a turtle urinary bladder preparation. These data led the investigators to conclude that impaired active hydrogen ion transport was responsible for the defect in distal acidification observed in toluene abusers. The anion gap is elevated in one-third of the cases of metabolic acidosis associated with toluene abuse (Carlisle et al. Accumulation of products of toluene metabolism, including benzoic acid and hippuric acid, is responsible for the elevated anion gap. Impaired renal function contributes to the accumulation of these anions and the development of high anion gap metabolic acidosis. In the presence of normal renal function, overproduction and urinary excretion of the anions of these organic acids contribute to the development of nonanion gap hyperchloremic metabolic acidosis (Carlisle et al. Pyuria, microscopic hematuria, and proteinuria are frequently observed after toluene exposure (Hayden et al. Nephrolithiasis due to toluene-induced distal renal tubular acidosis with hypercalciuria has also been reported (Kaneko et al. Isolated case reports have associated toluene abuse with antiglomerular basement membrane-mediated glomerulonephritis, focal glomerulosclerosis, and membranoproliferative glomerulonephritis (Beirne, 1972; Bonzel et al. However, a causal relationship between these disorders and toluene abuse remains to be established. Isolated case reports of antiglomerular basement membrane-mediated glomerulonephritis and hemolytic-uremic syndrome have also been reported in solvent abusers (Locatelli and Pozzi, 1983; Nathan and Toseland, 1979); however, a causal relationship is yet to be established. Heroin-associated focal and segmental glomerulosclerosis and secondary amyloidosis have been supplanted by human immunodeficiency virusassociated focal and segmental glomerulosclerosis and hepatitis C-related membranoproliferative glomerulonephritis. Concurrently, there has been an increase in the incidence and spectrum of nephrotoxicity associated with the use of cocaine and designer recreational drugs.

This structural difference has great significance for chemical reactivity as unsaturated aldehydes are two to three orders of magnitude more reactive than saturated aldehydes of similar carbon length. Nonetheless, aldehydes, in general, are ubiquitous components of the environment and their increased abundance is associated with increased risk of cardiovascular disease in humans. However, aldehyde abundance in the environment does not always spell doom because many familiar foods contain a variety of non-toxic aldehydes that in addition to providing flavor to foods. Some of these aldehydes are difficult to measure accurately and can change in chemical structure over time 516 Aldehydes and Cardiovascular Disease due to chemical interactions in the air. Although environmental aldehydes are inhaled by all members of the population, a shorter list of aldehydes through their direct use in industrial processes can lead to potentially dangerous occupational exposures associated with the generation/use of these aldehydes in these industries, such as in embalming and perfumery practices. This scenario has led to more than one illustrative example of the potentially harmful effects of aldehyde exposure.

Thomas R Cochran, Vivian I Franco, Rebecca Scully, and Steven E Lipshultz have updated the text throughout the article. Fortunately, earlier detection and improved treatment have increased the number of survivors. Limiting the efficacy of chemotherapy are pervasive late effects, particularly in children, where treatment can lead to lifelong morbidity (Oeffinger et al. Dysfunction translates to increased morbidity and mortality among long-term survivors. Self-reported health is significantly lower among long-term survivors, even in the absence of clinical cardiac dysfunction (Cox et al. Clinical cardiomyopathy, particularly when associated with anthracycline chemotherapy, is often refractory to treatment and carries a particularly poor prognosis (Felker et al. The Childhood Cancer Survivor Study reported a standardized mortality ratio for cardiac causes that was 8. Increased understanding of the molecular pathways of tumorigenesis has led to the development of targeted therapies. However, as with anthracyclines and radiation, trastuzumab has been associated with marked cardiotoxicity (Slamon et al. Although both trastuzumab and anthracyclines are associated with treatment-induced cardiotoxicity, the mechanisms are distinct. Type I chemotherapy-induced cardiotoxicity, that of anthracyclines, is progressive, nonreversible, and associated with cellular apoptosis. Trastuzumab, particularly when administered in combination with anthracyclines, has a toxicity that not only highlights the complexity of cell signaling pathways, but also offers greater insight into the mechanisms of toxicity and acute adaptation to stress in the heart muscle, neither of which is yet fully characterized. However, when the cardioprotectant dexrazoxane is administered before every dose of anthracycline, the additive cardiotoxicity of trastuzumab and anthracycline is mitigated (Ebb et al. In the early 1960s, daunorubicin was the first anthracycline to show effectiveness as an antitumor agent against acute leukemia in humans. Liposomal doxorubicin is efficacious in treating recurrent epithelial ovarian carcinoma and metastatic breast cancer (Harris et al. Epirubicin and idarubicin, anthracycline derivatives, are also widely used, particularly to treat advanced breast cancer and myelogenous leukemias (Robert et al. Pirarubicin, an anthracycline analogue, has been used to treat several malignancies, most recently acute myelogenous leukemia related to Down syndrome, in which rates of complete remission were high and rates of cardiotoxicity were extremely low (Kudo et al. Mitoxantrone, an anthraquinone, has antiviral, antibacterial, immunomodulator, and antitumor properties. Doxorubicin and daunorubicin each act as an electron acceptor and are reduced to semiquinone radical species (Davies and Doroshow, 1986). Mitochondria catalyze reduction, which is followed by rapid oxidation, spurring the generation of superoxides. At elevated concentrations, doxorubicin inhibits succinate dehydrogenase, succinate oxidase, and cytochrome c oxidase activities, which interrupts the electron transport chain (Marcillat et al. Genomic analysis in spontaneously hypertensive male rats provided further evidence that mitochondria are the primary target of the doxorubicininduced oxidative damage that causes cardiomyopathy and are also the site of its cardioprotective actions (Thompson et al. Other proposed theories for anthracycline-related cardiac damage include elevated concentrations of proinflammatory markers and progressive myocardial injury in the absence of repair. Several additional anthracycline-induced subcellular changes have been identified. Cardiomyocyte loss is likely the result of accumulated insults rather than the end result of a single pathway (Table 1) (Minotti et al. Anthracycline, Trastuzumab, and Cardiovascular Toxicity 435 Topoisomerase 2b has been found to be involved in anthracycline-induced cardiotoxicity (Zhang et al. Reduction in antioxidant enzyme gene transcription is also dependent on topoisomerase 2b (Zhang et al. Additionally, Topoisomerase 2b and anthracycline significantly reduce peroxisome proliferator-activated receptor-g coactivator 1-a and peroxisome proliferator-activated receptor-g coactivator 1-b, which are both critical to mitochondrial biogenesis (Zhang et al. Animal studies have found that topoisomerase 2b deletion protects mice from anthracycline induced cardiotoxicity (Veipongsa and Yeh, 2014a, 2014b). Pathologic findings related to this widespread degenerative chronic anthracycline cardiotoxicity include loss of myofibrils within cardiomyocytes, vascular degeneration, impaired mitochondrial generation, and interstitial fibrosis (Billingham et al. On a gross scale, as cardiomyocytes undergo apoptosis, the ventricular walls become thinner, and the remaining cells compensate through hypertrophy to maintain cardiac output (Lipshultz et al. Onset can be acute, occurring during therapy; early, occurring within months of treatment; or late, presenting a year or more after completing treatment. Risk factors and high-risk populations for ventricular dysfunction are highlighted where preventive or early therapeutic strategies may be effective. The circled numbers 1 through 5 indicate points of preventive or therapeutic interventions and in which biomarker measurements may be helpful. Toxicity is generally reversible and resolves when treatment is discontinued (Shankar et al. Although adults typically experience chronic dilated cardiomyopathy, children often present initially with dilated cardiomyopathy, which then progresses to a restrictive form. In a study of all Pediatric Oncology Group patients receiving anthracyclines between 1974 and 1990, 1. Of these 106 patients, cardiotoxicity was diagnosed in 95, either during therapy or during the first year after therapy. The incidence of late-onset cardiotoxicity increases with time and typically manifests as cardiomyopathy, which is often refractory to standard treatment (Lipshultz et al. However, at 15 years of follow-up, mean values were a full standard deviation below normal. Dashed lines are the upper and lower 95% confidence limits from the predicted mean. Stressors include pregnancy, surgery, weight-bearing exercise, weight lifting, and acute viral infection. Of 547 long-term survivors of childhood acute myelogenous leukemia, cardiotoxicity developed in 16 at a median follow-up of 5. Few data exist about late-onset anthracycline cardiotoxicity in long-term survivors of adults with cancer, although it is unlikely that adults are free from cardiac effects. Women with breast cancer often receive high doses of chemotherapy as well as mediastinal radiation, both of which can cause substantial cardiac damage (Rowlings et al. Congestive heart failure was particularly prevalent (standardized incidence ratio, 5. Among the breast cancer survivors in the United States over the age of 65, doxorubicin is associated with increased rates of cardiomyopathy (hazard ratio, 2. Cumulative dose is widely accepted as a risk factor, but peak delivery dose, age at diagnosis, concomitant radiation, female sex, genetic factors, and cardiac health before treatment also mediate cardiovascular risk (Lipshultz et al. A relationship between cumulative lifetime dose and cardiotoxicity is clear (Lipshultz et al. Several studies have found a significant incidence of late cardiotoxicity 10 or more years after treatment (Lipshultz et al. Anthracycline-induced cardiotoxicity is increased with current as well as previous exposure to certain other treatments. Radiation to the chest before anthracycline exposure increases the risk of toxicity, and previous treatment with anthracyclines increases the cardiotoxic effects of trastuzumab. It appears that early insults make the heart more susceptible to future adverse events (Adams and Lipshultz, 2005). Adults > 70 years old and children younger than 5 years old are at the greatest risk for cardiotoxicity (Von Hoff et al. Further, cardiac mortality is lower in children who are diagnosed after the age of 7 years (Lipshultz et al. Furthermore, the effect of sex increased at higher cumulative doses (Lipshultz et al. Excess mortality is also significantly higher in long-term female survivors of childhood cancer and in their male counterparts (Mertens et al. Trisomy 21 is also a risk factor for both myeloproliferative disorders and anthracycline-related cardiotoxicity (Krischer et al. Patients with preexisting cardiac disease are presumably at an increased risk of cardiac effects, though these patients are often excluded from long-term studies of treatment-related cardiotoxicity, making post hoc evaluation of this group difficult. One study that did include women with breast cancer and preexisting heart disease found it to be a significant risk factor for cardiomyopathy after anthracycline chemotherapy (Doyle et al. Mutations in the hemochromatosis gene interfere with iron metabolism, leading to iron overload, which increases the susceptibility of anthracycline-induced cardiotoxicity (Lipshultz et al. Obesity is common in cancer survivors, with women who received cranial radiation before the age of 5 years being 3. The risk of obesity after cranial radiation is increased in those receiving radiation doses of 20 Gy or higher, leaving men 1. The association between obesity and cranial radiation is thought to be the result of radiation-induced changes in growth hormone production and leptin sensitivity. Reduced peak delivery dose may help to limit the concentration of doxorubicin within the cardiomyocyte, reducing the potential for toxicity. However, the risk of subclinical cardiac dysfunction did not differ significantly groups (Van Dalen et al.
