HIV and Gynecology RAMONA PAULI HIV+ women have a higher risk of cervical dysplasia and cervical cancer purchase 200 mg zovirax fast delivery, genital ulcers trusted 400 mg zovirax, vaginal infections and genital condyloma than negative women order 800mg zovirax overnight delivery. A gynecol- ogical examination including a Papanicolaou (Pap) smear and screening for sexually transmitted infections are part of the routine evaluation of female HIV+ patients at the time of first diagnosis as well as during the course of the disease. Prophylaxis Guidelines on Pap smear and breast cancer screening for the general population vary from country to country. In general, Pap smear screening starts at age 20 or 25 and continues until about age 50 or 60. Breast cancer screening starts in Germany at age 35. Regular gynecological checkups, including Pap smears, are especially important for HIV+ women because of their higher risk of cervical and anal dysplasia. In contrast, the risk of breast cancer in HIV+ women is not elevated, it seems to be lower than in negative women (Goedert 2006). Physicians working with HIV+ women should stress the importance of gynecologi- cal evaluations. It cannot be taken for granted that all women will visit the gynecologist regularly even when it is covered by health insurance. In Germany for example only 50% of women take advantage of regular Pap smear and breast cancer screening. Therefore it is crucial to talk about the necessity and the reasons for gyne- cological screening. The frequency of screening depends on the clinical scenario. If the initial Pap smear after HIV diagnosis is normal, then a second screening should be done approximately 6 months later. If both results are normal, then an annual Pap smear is sufficient. Consider more frequent screening in women with a higher risk of cervical dysplasia, e. Table 1: Gynecological/Pap smear screening Screening frequency Clinical scenario Every year Routine control 6 months First year of HIV diagnosis, then every year <6 months Abnormal Pap smear HPV infection After therapy for cervical dysplasia Symptomatic HIV infection CD4 T cells <200/μl Basic gynecological evaluation A full gynecological examination consists of inspection of the external genital and perianal region, bimanual examination of the inner genital area, rectal examination, colposcopy, microscopic examination of vaginal secretions and a Pap smear. In HIV+ women palpation of inguinal and axillary lymph nodes is important, since enlarged lymph nodes are often present and may need a rapid mammographic/ultrasound evaluation. Since 2013, German- Austrian guidelines recommend an annual anal cytologic smear for all HIV+ men and women. HIV and Gynecology 523 Menstrual cycle/menopause Data on the influence of HIV on the menstrual cycle are conflicting. Older studies demonstrate a cycle prolongation (Shah 1994), whereas the WIHS study shows at most a slight increase of very short cycles (Harlow 2000). It is also unknown whether or not HIV accelerates the beginning of menopause. There is only limited data in small populations (Clark 2000, Greenblatt 2000). In contrast, it is clear that post- menopause as well as HIV infection and antiretroviral treatment have adverse effects on bone, lipid and glucose metabolism and may contribute to osteoporosis and cardiovascular disease. Contraception When choosing a contraceptive method be aware of the expectations of the woman. Condoms are the most common form of contraception (and they protect from STIs). Nevertheless their contraceptive effectiveness is comparatively limited. Condoms have a Pearl Index (number of pregnancies per 100 patient years) of 1–12 while con- traceptive pills have a Pearl Index of 0. Other methods are contraceptive pills containing varying hormone combinations and dosages, depot and transdermal for- mulations as well as intrauterine devices (IUD). Hormone-containing contraception has no influence on the course of HIV infection, but this method may increase the risk of transmitting or acquiring HIV (Stringer 2009, Heffron 2012). Intrauterine devices made of copper as well as the levonorgestrel-containing device (Mirena), which increases cervical mucus viscosity, have proved to be safe and effective in HIV+ women (Stringer 2007, Heikinheimo 2006).

More recent studies have come to the sobering conclusion that HIV remains detectable in latent infected cells buy generic zovirax 800 mg, even after long-term suppression discount zovirax 400mg overnight delivery. And Timothy Brown cheap zovirax 400 mg overnight delivery, the only person up to now who has been cured from HIV infec- tion (by an allogenous stem cell transplantation that transferred a rare genetic vari- ation to his immune system) remains a singular case. In fact, today’s reality seemed impossible ten years ago: HIV infection is a chronic disease which, although incurable, is manageable lifelong with therapy, even in patients with resistant virus. CCR5 antagonists as well as integrase inhibitors have opened up new possibilities of treatment. It has become increasingly possible to lower viral loads to below detection in most patients. The pioneer drugs maraviroc and raltegravir have been shown to be extremely well-tolerated. These new drug classes will bring about fundamental changes to current ART. The dogma of always using two nucleoside analogs as the backbone of every therapy may start to change. Many of the currently widespread drugs will disappear over the next few years. The end of HIVID, Agenerase, Fortovase or Viracept is just the beginning. Veteran agents like AZT, d4T, ddI, nelfinavir or indinavir are not recommended by guidelines anymore although they served us in HIV management in the nineties. Will we be needing saquinavir, fosampranavir or even efavirenz and lopinavir as much as we do today five years from now? A normal life expectancy seems realistic today with treatment. This will pose a tremendous challenge for patients, physicians and for the pharmaceutical industry and payors. The comfortable situation at present does not mean one can relax. There is uncertainty about whether our drugs can stand the test of time over decades. Effects on the heart, kidney, bones and other organs in an aging HIV population are difficult to foresee. If the cure is delayed, over the decades one will need a wider breadth and range of available drugs. It will not be easy for new drugs to be approved, as vicriviroc has shown. How do you show the advantages of a new drug over other successful ther- apies today? Approval for new drugs is becoming more strict and the market is tight- ening. Already one can observe the pharmaceutical industry’s caution. The days may be over when an HIV drug got from the laboratory to the market within five years. Compared to the previous decade, the HIV ARV pipeline is now drying up. At the same time, the simple question of “when to start” with ART has remained unanswered for a long time. Instead of David Ho’s recommendation from the nineties “hit hard, hit early”, we often heared “hit HIV hard, but only when necessary” (Harrington 2000) during the last decade. With the START study results appearing at the horizon, there is no doubt that this will change again. What roles do the following play: viral load, CD4 T cell changes, CD4 percentages, age, gender, host elements and viral tropism? These strategically important questions will hopefully find some answers through detailed analysis of the START study that are underway now. HIV clinicians are well-advised to keep an open mind to new approaches.

Disease-modifying drugs for multiple sclerosis Page 2 of 120 Final Report Update 1 Drug Effectiveness Review Project STRUCTURED ABSTRACT Purpose We compared the effectiveness and safety of disease-modifying drugs for the treatment of ® ® ® multiple sclerosis: Glatiramer acetate (Copaxone ) buy zovirax 400mg amex, interferon beta-1a (Avonex zovirax 200mg amex, Rebif ) generic zovirax 800mg visa, ® ® ® interferon beta-1b (Betaseron , Extavia ), mitoxantrone (Novantrone ), and natalizumab ® (Tysabri ). Data Sources ® We searched Ovid MEDLINE and the Cochrane Library and the Database of Abstracts of Reviews of Effects through December 2009. For additional data we also hand searched reference lists, government web sites and dossiers submitted by pharmaceutical companies. Review Methods Study selection, data abstraction, validity assessment, grading the strength of the evidence, and data synthesis were all carried out according to standard Drug Effectiveness Review Project review methods. Results In patients with relapsing remitting multiple sclerosis, little difference in relapse outcomes were ® ® found between interferon beta-1a SC (Rebif ) and interferon beta-1b (Betaseron ), while ® ® interferon beta-1a IM (Avonex ) was less effective than interferon beta-1a SC (Rebif ) and ® interferon beta-1b (Betaseron ) based on 4 fair-quality head-to-head trials. Direct evidence from 5 fair-quality head-to-head trials was conflicting on disease progression outcomes between the interferons. Pooled analysis of direct and indirect trial data found no difference between the ® interferons on changes in disability and no difference between interferon beta-1a SC (Rebif ) ® and interferon beta-1a IM (Avonex ) on disease progression but did find interferon beta-1b ® ® (Betaseron ) to be superior to interferon beta-1a IM (Avonex ) on disease progression (relative risk, 0. There was no difference in relapse or disease progression ® ® between glatiramer and interferon beta-1a SC (Rebif ) or interferon beta-1b (Betaseron ) based on 2 head-to-head trials. Evidence is insufficient to make any judgments regarding effectiveness in primary progressive or secondary progressive multiple sclerosis. Evidence suggested that all 3 interferon beta-1 products and glatiramer reduced the probability of converting from clinically isolated syndrome to clinically definite multiple sclerosis over 2 to 5 year periods. Evidence for interferon beta-1b SC ® ® (Betaseron ) and interferon beta-1a SC (Rebif ) indicated that consistent positive neutralizing antibody status with high titer increased relapse rates, by one-half to two-thirds, during longer Disease-modifying drugs for multiple sclerosis Page 3 of 120 Final Report Update 1 Drug Effectiveness Review Project periods of follow-up. This difference was not seen with follow-up of 2 years or less, and there was inadequate evidence to conclude that there is an impact on disease progression. No difference was found in withdrawal rates among beta interferons in head-to-head trials. Transaminase elevations were common with all beta interferon products, with little difference in rates of occurrence. There was a lower rate of depression in patients taking ® interferon beta-1a (Rebif ) compared with the other interferons based on limited trial data. Interferon beta-1b SC (Avonex ) was associated with ® the lowest rates of injection site reactions whereas interferon beta-1b SC (Betaseron ) and ® interferon beta-1b SC (Rebif ) had similar rates. Significant long-term concerns included progressive multifocal leukoencephalopathy in patients receiving natalizumab >12 months, lipoatrophy with prolonged use of glatiramer, and permanent amenorrhea in older women receiving higher total dose of mitoxantrone. There was some evidence that response to beta interferons and glatiramer differs in men and women, but there was no evidence that this difference favors one product over another. Evidence is insufficient to make conclusions about the safety of these drugs in pregnancy. A post ® hoc subgroup analysis of a head-to-head trial of interferon beta-1a products (Avonex and ® Rebif ) found that African-American patients experienced more exacerbations and were less likely to be exacerbation-free compared with white patients over the course of the study. Conclusion ® There was fair evidence that interferon beta-1a IM (Avonex ) is less effective than interferon ® ® beta-1a SC (Rebif ) and interferon beta-1b (Betaseron ) for preventing relapse in patients with relapsing remitting multiple sclerosis. On other outcomes and in other populations, direct evidence is either lacking or shows few differences in effectiveness or safety among the disease- modifying drugs used to treat multiple sclerosis.

In contrast buy zovirax 400 mg cheap, the proportion with no adverse events increased by 25% among 12 adults who continued with immediate-release methylphenidate buy 800 mg zovirax with mastercard. The statistical significance of this difference is unclear generic 800 mg zovirax, however, as analysis of the change was not presented and the study was limited by a small sample size and the presence of a between-groups imbalance at baseline in the proportion who 186 started out with no adverse effects. Immediate-release guanfacine compared with immediate-release dextroamphetamine The number of adverse events reported was similar in 17 adults after 2 weeks of once daily treatment with either immediate-release guanfacine 1. Muscle tension was the most common side effect with immediate-release dextroamphetamine (29%). Fatigue was the most common side effect with immediate-release guanfacine (23%). Withdrawals due to adverse events were not reported. Modafinil compared with immediate-release dextroamphetamine Modafinil and immediate-release dextroamphetamine were associated with similar rates of insomnia (38% compared with 19%, P=NS), muscle tension (24% compared with 19%; P=NS) 188 and appetite suppression (24% compared with 19%, P=NS). Attention deficit hyperactivity disorder 79 of 200 Final Update 4 Report Drug Effectiveness Review Project Indirect evidence Atomoxetine Adverse events were reported in all 8 placebo-controlled trials of atomoxetine of general samples 189-195 of adults with ADHD (Table 12). Withdrawals due to adverse events increased over time and were generally greater for atomoxetine than for placebo. Appetite disturbance was consistently significantly more common with atomoxetine than for placebo; whereas, the difference between atomoxetine and placebo was more variable with regard to insomnia. Adverse events in placebo-controlled trials of atomoxetine Author Year Treatment Withdrawals due to Appetite Sample size regimen adverse events disturbance Insomnia Spencer “Occurred “Did not occur 192 76 mg x 3 1998 4% vs. Immediate-release dextroamphetamine 198, 199 Some reporting of adverse events was available in both of 2 fair-quality trials. Between- group statistical comparisons were not reported in the 6-week trial of 51 adults, but rates were generally higher for immediate-release dextroamphetamine 23. In the second trial of 98 adults, after 20 weeks there was no significant difference between immediate-release dextroamphetamine 20 mg twice daily or placebo in withdrawals due to adverse events (13% compared with 8%), but rates of individual adverse events were not 198 reported. Attention deficit hyperactivity disorder 80 of 200 Final Update 4 Report Drug Effectiveness Review Project Extended-release dexmethylphenidate We included 1 fair-quality, placebo-controlled trial of 5 weeks of treatment with extended- 200 release dexmethylphenidate (N=221). There was no significant difference between extended- release dexmethylphenidate and placebo in withdrawals due to adverse events (11% compared with 8%), decreased appetite (18% compared with 11%), or insomnia (16% compared with 11%). Lisdexamfetamine 201 202 We included 1 fair-quality trial and 1 poor-quality trial of lisdexamfetamine. In the fair- quality trial, rates of various common adverse events were reported for lisdexamfetamine and placebo, but statistical analysis of between-groups differences was not reported. For lisdexamfetamine 30 mg, 50 mg, 70 mg, and placebo, respectively, rates of withdrawals due to adverse events were 3%, 7%, 7%, and 2% and rates of decreased appetite were 29%, 28%, 23%, and 2%. Using data from this trial, analysis of numerous aspects of the impact lisdexamfetamine had on sleep quality was presented in a subsequent publication. It was unclear whether all the sleep analyses were prespecified. Although statistical analysis of between-group differences was not reported, the rates of treatment-emergent insomnia were numerically greater for all 3 doses of lisdexamfetamine compared with placebo and a dose-response may have been in effect (19% 243 for 30 mg, 17% for 50 mg, and 21% for 70 mg compared with 5% for placebo). Mixed amphetamine salts immediate-release We included 1 fair-quality, crossover trial that compared 3 weeks of treatment with mixed amphetamine salts immediate-release 54 mg to placebo in 30 adults (50% male, mean age of 38 204 years). Compared to placebo, there was a significantly greater proportion of patients taking mixed amphetamine salts immediate-release with a loss of appetite (30% compared with 11%; P=0. Withdrawals due to adverse events were not reported. Mixed amphetamine salts extended-release Both of 2 fair-quality included trials of mixed amphetamine salts extended-release reported rates of various common adverse events, but results of a statistical comparison to placebo were not 193, 205 reported. In the first 4-week trial (N=255), for mixed amphetamine salts extended-release 20 mg, 40 mg, 60 mg, and placebo, respectively, rates of adverse event withdrawals were 14%, 9%, 13%, and 2%; rates of anorexia were 20%, 42%, 38%, and 3%; and rates of insomnia were 205 21%, 30%, 26%, and 13%. In the second 3-week trial of 19 young adults, for mixed amphetamine salts extended-release 50 mg and placebo, respectively, rates of adverse event withdrawals were 11% and 10%, rates of anorexia were 50% and 0%, and rates of insomnia were 193 19% and 0%. Immediate-release methylphenidate Adverse event report was extremely limited in trials of immediate-release methylphenidate.
