Ultrasonographic US ; -guided detection of prostate cancer is limited by the inability of conventional gray-scale and Doppler US to enable one to adequately distinguish malignant from benign prostate tissue. With gray-scale US, cancer of the prostate is classically described as hypoechoic in the peripheral zone but often appears isoechoic and can even appear hyperechoic 1, 2 ; . Because of the increased local angiogenesis associated with cancer of the prostate, improved cancer detection may be achieved on the basis of the color Doppler US blood flow characteristics of prostate cancer 3, 4 ; . However, both prostatitis and benign prostatic hyperplasia BPH ; are associated with increased Doppler US flow, and neither color nor power Doppler US results are specific for the diagnosis of prostate cancer 57 ; . Dutasterlde Avodart; Glaxo-Smith-Kline, Phildadelphia, Pa ; , a type I II 5 reductase inhibitor, is approved for treatment of symptomatic BPH. Preliminary data for the selective type II 5 reductase inhibitor finasteride suggest that prostatic blood flow may be reduced after short-term therapy with it for several weeks 8 ; . This effect is probably related to a decrease in microvessel density within benign prostatic tissue 9 ; . We reasoned that the reduction in Doppler US signal from the prostate is likely to be even more marked after.

Prevalence of antimicrobial resistance among clinical isolates of haemophilus influenzae : a collaborative study. The importance of baseline prostate volume on treatment effectiveness. Changes in urinary symptoms and prostate volume were observed. In patients treated with the drug throughout the study, the mean reduction in prostate volume over 48 months was 30.3% for those with a baseline prostate volume of 30 cc less, and 26.2% for those with a prostate volume of 40 cc greater. Improvements in urinary flow were found to be independent of baseline prostate volume. The risk of acute urinary retention was reduced by 55-60% in the group on the drug for 48 months, and vs. those treated for only 24 months. The risk of needing BPH related surgery, when compared to those receiving only 24 months of treatment, was reduced by 27% and 48% for those receiving 48 months of treatment with baseline prostate volumes either equal to or less than 30 cc or equal to or greater than 40 cc, respectively. In a smaller open-label study [6] of treatment with dutasteride, a large percentage of the patients assessed achieved a significant decrease in lower urinary tract symptoms, and improvements in patient discomfort and satisfaction scores. In this cohort of 366 patients, most had moderate to severe symptoms and had been previously treated with alpha-blockers or phytotherapy or a combination of the two. The minimum prostate volume was estimated at 30 cc. Most of the improvements in symptoms associated with urinary function were seen during the first 12 weeks of treatment. Side effects were mostly associated with sexual disorders. Of the 44 patients who had sexual dysfunction during the treatment period, 10 had these complaints at study entry. In a large study of side effects of 5ARIs, it was found that dutasteride was well tolerated during long-term use for the treatment of symptomatic BPH. This study also confirmed that side effects associated with 5ARIs tend to diminish with the period of treatment and eventually persist in only a very small percentage of patients [5]. These studies are significant in the context of pharmaceutical treatment of BPH because research suggests that finasteride should be reserved for patients with prostate volumes over 40 cc but even men with prostate volumes between 30 and 40 cc are at increased risk for acute urinary retention which produces a medical emergency and in many cases leads to invasive action to improve urinary flow. Also, as discussed in our book, alpha-blockers, the first-line treatment for BPH, do not in general reduce prostate size or the long-term risk of acute urinary retention, a result of severe BPH that men fear the most. In addition, the effect of dutasteride on PSA has now been investigated [8] and justification found for using a multiplier of two in interpreting this marker in men taking dutasteride in order to correct for the decrease in PSA that occurs. The observed decrease in PSA stabilized between 6 and 12 months after initiation of treatment, and the authors conclude that an increasing PSA in men receiving dutasteride should be viewed with suspicion and serial measurements instituted to evaluate changes from the minimum reached. It helped with my depression, but just killed my sex life and alfuzosin. 4 INTRODUCTION The hypothalamus, pituitary and testes produce endocrine hormones responsible for regulation of the prostate and other male sexual functions 12, 46 ; . Exogenous endocrine active compounds can disrupt these processes. Some pesticides e.g., vinclozolin and linuron ; are known to have antiandrogenic activity 19, 20 ; . Toxic effects of antiandrogens in male rodents range from developmental effects, such as reproductive malformations, retained nipples and undescended testes, to pubertal effects, such as delayed puberty and reduced weights of prostate and other reproductive organs. In the pharmaceutical setting, therapeutic drugs such as finasteride, dutasteride, bicalutamide, and flutamide are used to treat benign prostatic hyperplasia and or prostate cancer by inhibiting androgen-dependent growth processes. The mechanisms of action of antiandrogens are generally of two forms. The first is the androgen antagonist, which binds to the AR but does not stimulate DNA transcription, such as the pharmaceutical compounds flutamide and bicalutamide, or the environmental compound vinclozolin. The second is the 5 -reductase inhibitor, which blocks the metabolism of T to DHT. The therapeutic drugs dutasteride and finasteride are examples of 5 -reductase inhibitors; no environmental examples are currently known. Both of these mechanisms effectively inhibit AR-mediated DNA transcription, leading to reduction of prostate size and cell numbers and decreased prostatic fluid production. Quantification of the male regulatory processes and their disruptions would aid in the dose-response assessment of environmental endocrine active compounds 4, 5 ; . This requires biologically based quantitative methods describing not only the pharmacokinetics and mode of action of the exogenous compound of interest, but also the pharmacokinetics of the endogenous hormones and how they regulate the male reproductive organs.

Terone levels, they would not have fulfilled the entry criteria for this study. However, these data are consistent with previously published studies showing that prostate volume and serum PSA do not correlate with serum testosterone 17, 18 ; . These observations may reflect the fact that in the prostate, testosterone is converted to the more potent androgen DHT by high levels of 5 -reductase, and it is the resultant high levels of DHT that enhance the androgen signal in the prostate 7, 8 ; . Hence, one role of 5 -reductase in the prostate may be to allow the prostate to function normally and undergo age-related growth, even in the presence of low circulating testosterone levels. As a consequence, despite the increasing prevalence of low serum testosterone levels among aging men, BPH is common. Furthermore, the beneficial effects of dutasteride on BPH could therefore be expected, even in men with low testosterone levels. The absence of a consistent pattern of treatment differences between dutasteride and placebo across the range of baseline testosterone levels evaluated in these analyses supports this hypothesis. The 52 men with the lowest BST levels of less than 150 ng dl behaved differently from the rest of the study population: they were slightly older; had larger prostates and a greater increase in prostate volume over time with placebo; and had higher BMI, greater incidence of ED, altered libido, lower SFI, and greater decrease in sexual function over time with placebo. These findings could be a manifestation of obesity-associated metabolic syndrome and are worthy of further examination in other data sets. In conclusion, sexual function in men is partially dependent on serum testosterone, but many men have normal sexual function at low circulating androgen levels. Serum testosterone level is therefore a poor predictor of sexual dysfunction in men with BPH. On the other hand, androgenic stimulation of the prostate is largely independent of serum testosterone, at least in the range of testosterone levels examined in this study. This explains why BPH can occur in men who would otherwise be considered hypogonadal. By maximally inhibiting 5 -reductase activity, dutasteride is effective at treating BPH, regardless of serum testosterone levels. NOTE: 1.

DOSAGE AND ADMINISTRATION The capsules should be swallowed whole and not chewed or opened, as contact with the capsule contents may result in irritation of the oropharyngeal mucosa. AVODART may be administered with or without food. 2.1 Monotherapy The recommended dose of AVODART is 1 capsule 0.5 mg ; taken once daily. 2.2 Combination With Alpha-Blocker The recommended dose of AVODART is 1 capsule 0.5 mg ; taken once daily and tamsulosin 0.4 mg taken once daily. 2.3 Dosage Adjustment in Specific Populations No dose adjustment is necessary for patients with renal impairment or for the elderly [see Clinical Pharmacology 12.3 ; ]. Due to the absence of data in patients with hepatic impairment, no dosage recommendation can be made [see Specific Populations 8.7 ; and Clinical Pharmacology 12.3 ; ]. 3 side. 4 CONTRAINDICATIONS AVODART is contraindicated for use in: Pregnancy. Eutasteride inhibits the activity of 5-reductase, which prevents conversion of testosterone to dihydrotesterone, a hormone necessary for normal development of male genitalia. In animal reproduction and developmental toxicity studies, dutasteride inhibited development of male fetus external genitalia. Therefore, AVODART may cause fetal harm when administered to a pregnant woman. If AVODART is used during pregnancy or if the patient becomes pregnant while taking AVODART, the patient should be apprised of the potential hazard to the fetus [see Warnings and Precautions 5.1 ; , Use in Specific Populations 8.1 ; ]. Women of childbearing potential [see Warnings and Precautions 5.1 ; , Use in Specific Populations 8.1 ; ]. Pediatric patients [see Use in Specific Populations 8.4 ; ].

Timus and Grassly 2001 ; identify two methods of estimating the number of double orphans. The first is to estimate the number of maternal orphans and then to calculate the proportion of maternal orphans whose father would have died in each year. The second is to make use of a regression model fitted to Demographic and Health Survey DHS ; data on the numbers of maternal and paternal orphans from various subSaharan African countries. Timus and Grassly favour the latter approach on the. LDL was isolated from 28 individuals; VLDL and IDL were isolated from 24 of these individuals Table 2 ; . Three VLDL samples and two IDL samples did not contain a sufficient amount of protein to use in the gel mobility shift assay. From representative examples of gels using this assay, it can be seen that with increasing concentrations of lipoprotein and a constant amount of [35S]SO4biglycan in each lane, there is an increasing amount of [35S]SO4-biglycan retained at the origin representing "bound" biglycan ; and a decreasing amount of [35S]SO4biglycan at the gel's front, which is "free" biglycan Fig. 1A ; . Binding curves generated for the interactions demonstrated that VLDL, IDL, and LDL all bound biglycan with various degrees of affinity Fig. 1B ; . Linear Scatchard plots Fig. 1B, inset ; are consistent with the idea that there is one class of binding sites for the interaction of apolipoproteins and proteoglycans 5 ; . The extent of biglycan binding was evaluated in two additional ways: first, the mean percent biglycan that bound to 0.05 and 0.1 mg total protein ml lipoprotein was determined. Second, affinity constants Ka ; for the binding interaction were calculated. Using both methods of analysis, LDL demonstrated the greatest ability to bind biglycan, followed by IDL and VLDL Table 3 ; . In addition, we observed that within an individual subject, biglycan binding to the smaller, denser LDL subfractions was greater than to the large, buoyant subfractions Table 3 ; . Taken together, these data suggest that the density of lipoproteins was related to their affinity for biglycan. In addition, the density of the lipoproteins and LDL subfractions were inversely correlated with their valence, surface potential, and charge density r 0.71, P 0.001 for each ; . It should be noted that the lower the charge value, the more positively charged the particle is. Thus, consistent with previous reports 28 ; , a lipoprotein's density is related to its overall charge, such that VLDL was the least positively charged lipoprotein, followed by IDL and then LDL. Furthermore, the amount of biglycan that bound to the lipoproteins was inversely correlated with valence, surface po1972 Journal of Lipid Research Volume 43, 2002.

Endocarditis is an inflammation or infection of the endocardium, which is the inner lining of the heart muscle and, most commonly, the heart valves. It is usually caused by a bacterial infection. The bacteria cluster on and around the heart valves; this may impair their ability to function properly. The acute form of endocarditis may cause more severe symptoms, while symptoms of the chronic form may be milder, making it more difficult to diagnose. WHO GETS IT? Although bacterial endocarditis may occur in anyone at any time, it is unusual in persons who do not have valvular heart disease. Valves deformed by a previous attack of rheumatic fever were once a major predisposing factor, but this is less so today since rheumatic fever has become much less common. Other predisposing factors include artificial heart valves, some congenital heart disorders, and, infrequently, mitral valve prolapse. People with such risk factors are more likely to develop endocarditis when exposed to an infection from any source. Dental surgery, urologic or gynecologic surgery, colonoscopy, and skin infections increase the risk of endocarditis. Intravenous drug users are at particular risk for development of endocarditis, even if there is no preexisting anatomic valve deformity. WHAT ARE THE SYMPTOMS? The symptoms of bacterial endocarditis include a lowgrade fever, fatigue, loss of appetite, night sweats, chills, headaches, joint discomfort, and tiny pinpoint-sized hemorrhages on the chest and back, fingers, or toes. Upon examination, the physician also may detect a new heart murmur and small hemorrhages in the mucous membranes of the eyes. HOW IS IT DIAGNOSED? Diagnosis is usually suspected based on the patient's history, symptoms, and findings such as a new murmur. It is confirmed by a blood test "culture" ; to identify an infecting organism. An echocardiogram may occasionally be helpful in identifying a clump of bacteria on the heart valve. HOW IS IT TREATED? Bacterial endocarditis almost always requires hospitalization for antibiotic therapy, generally given intravenously, at least at the outset. Occasionally, therapy with oral antibiotics at home will be successful. Antibiotic therapy usually must continue for at least a month. In unusual cases, surgery may be necessary to eliminate areas of infection or to repair or replace a damaged heart valve. TESTOSTERONE LEVELS AND PROSTATE CANCER Page 7 progression of BPH; however, its effects on incidence and severity of prostate cancer remains to be established. In late 2002, a new 5-alpha-reductase inhibitor became commercially available - dutasteride trade name Avodart ; . It inhibits type 1 and type 2 5-alpha-reductase. Type 2 is exclusively found in intraprostatic tissue. Type 1 is also found in the liver and skin. Studies have shown that Proscar lowers serum DHT levels by about 70%. Dutasteride lowers serum DHT by over 90%, with 85% of men achieving a 90% or greater reduction by 12 months. After just one month of dutasteride, 58% of men had already achieved this 90% reduction. However, what is most important to patients with prostate cancer is whether dutasteride lowers intraprostatic DHT better than Proscar. According to unpublished data on file with the manufacturer, dutasteride lowered intraprostatic DHT to lower levels than unpublished Proscar data. We need more reliable information before we can accept this as factual. We know that men on Proscar have their testosterone levels increase. In our triple hormone blockade protocol, an average increase was about 10%. What excites me is that Avodart raises the serum testosterone levels by about 24% at two years. What really interests me further is that the greatest changes in testosterone were found in men who presented with subnormal baseline testosterone levels. I believe that for most men, the higher the testosterone, the better the prognosis. If dutasteride raises testosterone levels more than Proscar, it is certain that we will be investigating any possible antiprostate cancer benefit with dutasteride compared to Proscar. The major take-home message in the paper you are reading is my belief that high testosterone levels are beneficial for men with prostate cancer. In the same dutasteride article from Urology, 2002, 60 30 ; , pages 434-441, the authors, Claus Roehrborn et al., report that PSA levels fell about 52% on Avodart. This is a similar reduction in PSA that men on Proscar achieve. The side Proscar. effects for dutasteride were fairly similar to. Molina J.

Figure 5 Signaling in castration-resistant prostate cancer and potential points of therapeutic intervention. After synthesis, the AR exists in dynamic equilibrium between an immature state and an active form capable of binding high-affinity androgenic ligands via association dissociation with a complex that includes heat-shock proteins, p23 and a tetratricopeptide TPR ; -containing protein. a ; Receptor-dependent, ligand-mediated signaling. Ligand binding results in the dissociation of this complex, receptor dimerization and phosphorylation, nuclear transport, DNA binding, the recruitment of components of the transcription machinery and other cofactor molecules, such as the p160 coactivators, and ultimately, the activation of particular gene pathways. b ; Receptor-dependent, ligand-independent signaling. The AR can also be activated in the absence of ligand by membrane-bound tyrosine kinase receptors such as HER2 neu, and by signaling molecules, growth factors and cytokines. Intracellular kinase cascades result in receptor activation, transport, binding to androgen response elements and the transactivation of target genes. 15. Mechanisms of continued androgen signaling implicated in maintaining prostate cancer growth in a castrate environment after androgen ablation therapy. 1. Tumor cells may acquire mechanisms to accumulate androgens, such as sequestration by steroid hormone binding globulin SHBG ; or altered regulation of enzymes involved in the synthesis and metabolism of androgens. 2. Castrate-resistant clinical prostate cancer samples often exhibit increased AR concentrations compared with early-stage tumors or normal prostate cells. This may result from amplification or overexpression of the AR gene. 3. AR gene mutations can allow promiscuous activation of the AR by alternative ligands, such as glucocorticoids, estrogens, adrenal androgens, progestins and traditional receptor antagonists such as hydroxyflutamide. Other mutations may alter the recruitment of cofactors. 4. Cross-talk with other signaling pathways may activate the AR in the absence of native ligands. 5. An altered profile of AR coregulators coactivators and corepressors ; may facilitate ligand-independent AR signaling, or enhance AR activation by low levels of ligand. ivii ; . Potential points of therapeutic intervention: i ; 5a-reductase inhibitors e.g. finasteride, dutasteride ii ; antisense AR oligonucleotides; iii ; Hsp90 inhibitors e.g. 17allylaminogeldanamycin iv ; AR inhibitors, antibodies, histone acetylase and deacetylase inhibitors e.g. SAHA v ; specific response element blockers e.g. polyamides vi ; growth factor receptor antibodies e.g. herceptin vii ; inhibitors of MAPK, the JAK-STAT pathway or Akt. Terone levels, they would not have fulfilled the entry criteria for this study. However, these data are consistent with previously published studies showing that prostate volume and serum PSA do not correlate with serum testosterone 17, 18 ; . These observations may reflect the fact that in the prostate, testosterone is converted to the more potent androgen DHT by high levels of 5 -reductase, and it is the resultant high levels of DHT that enhance the androgen signal in the prostate 7, 8 ; . Hence, one role of 5 -reductase in the prostate may be to allow the prostate to function normally and undergo age-related growth, even in the presence of low circulating testosterone levels. As a consequence, despite the increasing prevalence of low serum testosterone levels among aging men, BPH is common. Furthermore, the beneficial effects of dutasteride on BPH could therefore be expected, even in men with low testosterone levels. The absence of a consistent pattern of treatment differences between dutasteride and placebo across the range of baseline testosterone levels evaluated in these analyses supports this hypothesis. The 52 men with the lowest BST levels of less than 150 ng dl behaved differently from the rest of the study population: they were slightly older; had larger prostates and a greater increase in prostate volume over time with placebo; and had higher BMI, greater incidence of ED, altered libido, lower SFI, and greater decrease in sexual function over time with placebo. These findings could be a manifestation of obesity-associated metabolic syndrome and are worthy of further examination in other data sets. In conclusion, sexual function in men is partially dependent on serum testosterone, but many men have normal sexual function at low circulating androgen levels. Serum testosterone level is therefore a poor predictor of sexual dysfunction in men with BPH. On the other hand, androgenic stimulation of the prostate is largely independent of serum testosterone, at least in the range of testosterone levels examined in this study. This explains why BPH can occur in men who would otherwise be considered hypogonadal. By maximally inhibiting 5 -reductase activity, dutasteride is effective at treating BPH, regardless of serum testosterone levels.
