Most of the patients had relapsing-remitting multiple sclerosis (79%) with a baseline median annualized relapse rate and Expanded Disability Status Scale score of 1 purchase antivert 25 mg on line treatment yeast infection. No ® difference was found in the annualized relapse rate (interferon beta-1b [Betaseron ] 0 buy generic antivert 25 mg on line medications with codeine. Because these were secondary outcomes, the study may not have had an adequate sample size (statistical power) to identify a statistically significant difference if one exists. It did, however, agree with findings from 2 other trials where the population was restricted to relapsing-remitting multiple sclerosis, both of which found no difference in clinical measures including relapse rate between the interferon studied and 58, 59 glatiramer acetate (see section on relapsing-remitting multiple sclerosis, above). Mixed populations: Relapsing-remitting and secondary progressive multiple sclerosis Beta interferons A cohort study of relapsing-remitting multiple sclerosis and secondary progressive multiple ® sclerosis patients compared quality of life in patients treated with interferon beta-1b (Betaseron ) 88 to untreated controls. Patients were recruited during regular office visits and asked to complete a quality-of-life questionnaire based on the previous month. Additional data regarding hospitalizations and days of work/leisure time lost for the 3 months preceding study entry were also collected. When patients were stratified according to disease severity, those patients with the lowest Expanded Disability Status Scale (<3. While these data suggested that baseline disease severity had an important impact on quality-of-life measures, additional data from well- designed randomized controlled trials and/or observational studies assessing these measures are needed in order to draw more definitive conclusions.

Natalizumab Indirect evidence ® Three trials compared natalizumab (Tysabri ) to placebo in relapsing-remitting and secondary 89-91 progressive multiple sclerosis patients. While there were some similarities in patient characteristics across the trials, the size and quality of the trials varied and relevant baseline data was not uniformly reported across all trials. Natalizumab doses were weight-based in 2 of the trials whereas in the O’Connor et al trial, the patients were randomized to placebo, a 1 mg/kg 90 dose, or a 3 mg/kg dose and received only 1 infusion at study entry. The only infusing dosage that was common amongst the trials was 3 mg/kg but the total accumulated dose varied 89-91 considerably from 1 mg/kg to 18 mg/kg. For data comparing the same infusion dose of 3 mg/kg, we pooled the data to find the combined mean difference in Expanded Disability Status Scale score and found no significant difference between the natalizumab and placebo groups at 89-91 the final time point (−0. The total number of relapses reported in each study arm varied considerably between the trials. Miller et al reported a 4% relapse rate, O’Connor a 2% relapse rate, and Tubridy reported a 39% relapse rate. Relapse rates for placebo were 21%, 5%, and 44% respectively, resulting in a significant difference between natalizumab and placebo in 89 only 1 of the trials. Possible reasons for this discrepancy include total natalizumab dose (18 mg/kg compared with 1 or 3 mg/kg compared with 9 mg/kg respectively), trial duration (12 months compared with 14 weeks compared with 24 weeks of follow-up), and criteria used to assess relapse. Miller et al used a more restrictive criterion to determine relapse (physician- assessed, sustained for at least 48 hours) than did Tubridy (Poser criteria, either objectively or 16 subjectively defined, sustained for 24 hours). Due to the heterogeneity of the 3 trials Disease-modifying drugs for multiple sclerosis Page 43 of 120 Final Report Update 1 Drug Effectiveness Review Project 2 (I =79. Due to these discrepant findings, it is difficult to draw a definitive conclusion regarding the effect of natalizumab on relapse rate.

Mitoxantrone Indirect evidence ® A well-conducted systematic review compared mitoxantrone (Novantrone ) to placebo using 92 data from 4 trials (Table 16). A second review included the same 4 trials as well as preliminary 93 and unpublished data from an ongoing study. Among the 4 trials included in both reviews, there was some heterogeneity among the types of patients, mitoxantrone doses employed, and 94-96 study duration. Three of the studies enrolled mixed patient populations while the remaining 72 study enrolled only relapsing-remitting multiple sclerosis patients and had a lower mean baseline Expanded Disability Status Scale score (further discussion of the results of this trial appear in the relapsing-remitting multiple sclerosis section of this report). Mitoxantrone doses also varied widely across the included studies, while study duration ranged from 6 to 32 months. Disease-modifying drugs for multiple sclerosis Page 44 of 120 Final Report Update 1 Drug Effectiveness Review Project Mitoxantrone was found to be more effective than placebo in reducing relapse rate and 92 disease progression. No statistically significant difference in Expanded Disability Status Scale at 1 year was detected in a small subset of patients (data available from 1 study) but 2-year results from a larger group of patients did statistically favor mitoxantrone (Table 17).

Summary of findings General efficacy The evidence on the general efficacy for most drugs is sparse cheap antivert 25 mg line treatment tinnitus, fraught with methodological issues buy generic antivert 25mg line treatment magazine, or entirely missing. No controlled evidence is available for docusate calcium, docusate sodium and lactulose for the treatment of chronic constipation in adults. Three trials provide moderate strength evidence on the general efficacy of PEG 3350 for the treatment of chronic constipation. None of these studies, however, had a follow-up of more than 2 weeks. Inferences about the long-term efficacy of PEG 3350, therefore, cannot be drawn. The available evidence on the general efficacy of psyllium is limited to two studies of mixed methodological quality. Although both studies indicated a beneficial treatment effect for psyllium, bias cannot be ruled out, and no firm conclusions about efficacy can be drawn. Studies assessing the efficacy of lubiprostone have been published as abstracts only. The available information, therefore, is insufficient to critically appraise the underlying methods and draw firm conclusions. Tegaserod was taken off the market in March 2007 because of an increased risk of cardiovascular events. Multiple studies provide evidence on the general efficacy of tegaserod for the treatment of chronic constipation. Constipation Drugs Page 21 of 141 Final Report Drug Effectiveness Review Project Comparative efficacy No head-to head evidence is available for most comparisons of constipation drugs. Available evidence is limited to three head-to-head trials on comparisons of docusate sodium versus psyllium, lactulose versus PEG 3350, and PEG 3350 versus psyllium. Two out of three studies had severe methodological limitations and were rated as poor. A poor quality RCT indicated no difference in efficacy between docusate sodium and psyllium. Another poor quality RCT reported a greater improvement of symptoms for patients on PEG 3350 than on lactulose after 4 weeks of treatment. Findings of both studies must be interpreted cautiously because bias cannot be ruled out. The comparison of PEG 3350 with psyllium is limited to one fair open-label RCT. This study indicated a statistically significantly greater rate of improvements in patients on PEG 3350 than on psyllium. No controlled evidence is available for docusate calcium, docusate sodium and lactulose. Detailed assessment General efficacy and effectiveness Table 7 summarizes the trials assessing the general efficacy of constipation drugs in adults; Table 10 summarizes the evidence profile of the general efficacy of constipation drugs. Docusate calcium We did not find any studies on the general efficacy and effectiveness of docusate calcium that met our eligibility criteria. Docusate sodium We did not find any studies on the general efficacy and effectiveness of docusate sodium that met our eligibility criteria. Lactulose We did not find any studies on the general efficacy and effectiveness of lactulose that met our eligibility criteria. Constipation Drugs Page 22 of 141 Final Report Drug Effectiveness Review Project Lubiprostone We did not find any evidence on the efficacy of lubiprostone published as full text articles. The literature 20-30 search, however, detected 12 published abstracts. Most trials were of relatively short durations (3 to 4 weeks). In general, lubiprostone had a statistically significant treatment benefit compared with placebo. Consistently higher percentages of patients on lubiprostone than on placebo had spontaneous bowel movements within 24 hours. Only one open-label study over 24 weeks suggested a durable response of 22 lubiprostone.

Kaposi’s Sarcoma CHRISTIAN HOFFMANN, STEFAN ESSER Kaposi’s sarcoma (KS) is the most common malignancy in patients with HIV infec- tion. In 1981, the simultaneous occurrence of KS with pneumocystis pneumonias in young gay men led to the first descriptions of AIDS. This entity is designated after the Hungarian dermatologist Moritz Kaposi who first described the “classical” KS 100 years earlier. Classical KS predominantly occurs in elderly, but otherwise healthy people from the Eastern Mediterranean area. It affects often only the skin at the lower extremities and thereby, clearly differs from HIV-associated KS which will be the focus of the following chapter. In contrast to classical KS, HIV-associated KS may affect all skin and mucous mem- branes. Lymph nodes and internal organs such as stomach, gut, lung or liver may also be involved. The progression of HIV-associated KS is very variable and reaches from small lesions, remaining stable for years, to extremely aggressive courses, in which progression may lead to death within a few months. Compared to the 1980s and early 1990s, when KS was one of the most common AIDS illnesses, prevalence of KS today is relatively low (Francesci 2010) and the inci- dence has fallen to less than a tenth of what it was (Grabar 2006, Simard 2011). The refractory variants with an aggres- sive, devastating and often fatal course which were seen in the pre-HAART era have become a rarity today. However, mortality of KS patients remains elevated even after initiation of ART, especially during the first year (Maskew 2013). Moreover, there are still some very aggressive cases occurring today, typically only a few weeks or months after ART initiation. This so-called IRIS-associated KS often comes with rapid visceral lesions and high mortality (Crane 2005, Achenbach 2012, Letang 2013). High HHV-8 and HIV viremia seem to be risk factors for this IRIS-associated KS (Letang 2013). Pathogenesis The cellular origin of the spindle cells (considered the KS tumor cells) is still controversial. Newer investigations suggest lymphatic, endothelial cells (Dupin 2006).

Pruritus: Chronic generic 25mg antivert free shipping symptoms 5dp5dt, often unremitting pruritus is one of the most frequent clinical symptoms of HIV infection antivert 25mg generic medicine 1920s. In most cases, etiology remains unclear and only symptomatic treatment can be offered which may be unsat- isfying (Moses 2003, Singh 2003). Pruritus can be a complication of infectious dis- 618 Interdisciplinary Medicine eases, such as viral, bacterial, fungal infections (e. Also, dry eczematous skin (xerosis), papulosquamous skin diseases, systemic lymphomas, renal insufficiency and hepatic disease are causative conditions. Finally, many antiretrovirals and other drugs can cause pruritus (with or without rash). To diagnose idiopathic pruritus it is necessary to exclude all skin and systemic diseases mentioned above. In patients on ART it can be useful to change the treatment regimen. Systemic antihistamines and topical corticosteroids are symptomatic treatment standards. If they are ineffective, or a prolonged systemic treatment is necessary, phototherapy (UVA-1, UVB 311nm) or photochemotherapy (PUVA) is an alternative or adjuvant therapy (Smith 1997, Gelfand 2001, Zirwas 2001, Singh 2003). Concerning the immunosuppressive effects of ultraviolet light, it seems that patients on ART are at less risk. Papular dermatoses: Patients can present either with monomorphic skin colored to red papules (size 2–5 mm) or with combined eruptions consisting of papules and pustules (sterile eosinophilic pustulosis, Ofuji’s disease). According to the clinical presentation and laboratory findings (elevation of IgE, eosinophilia in peripheral blood and affected skin) they resemble the prurigo of atopic dermatitis found in adults. Autoimmune reactions against follicular antigens have also been discussed , such as eosinophilic folliculitis (Fearfield 1999). These papules can be due to a hypersensitivity reaction to drugs, microbiological agents (viruses, bacteria, fungi), parasites or saprophytes (Sarcoptes scabiei, Demodex folliculorum, Pityrosporum ovale and others). A thorough history of drugs, microbiological and histological exam- inations (including special stains such as PAS) are required for a correct diagnosis. If possible, specific infectious agents are treated. In case of sterile eosinophilic pus- tulosis (Ojufi’s disease) or papular dermatosis of unknown origin, therapy is symp- tomatic. Depending on the clinical situation, antihistamines, itraconazole (200 mg/d for 2 weeks), isotretinoin, dapsone, mild PUVA or UVB (311nm narrowband UVB is the most effective therapy) or 5% permethrin cream can be tried (Ellis 2004). Paronychia and ingrown nails: Ingrown toenails and inflammatory reactions of the proximal nailfold are a well known complication in diabetics, but also in patients on beta-blockers or retinoid therapy. A few cases might be due to local pressure (wrong shoes) or occur spontaneously. Patients on ART are the latest group of patients to regularly develop ingrown nails. These are ascribed to retinoid-like side effects of several antiretrovirals, especially indinavir, but also 3TC. Usually, the large toenails are involved, but all other toenails and fingernails can be affected. Complete remis- sion is often seen when indinavir or 3TC are replaced by other antiretrovirals. Surgical measures such as Emmert-plasty or its modification after Hanneke, should only be performed when changing ART has not led to remission after 3 to 6 months (Tosti 1999, Alam 1999, Garcia-Silva 2002). Psoriasis vulgaris: Today, psoriasis is regarded as a polygenic dispositional, chronic systemic autoimmune disease determined by multifactorial inheritance with variable penetrance and affects approximately 2% of the general population. Characteristic cutaneous lesions result from inflammatory reactions with increased proliferation and inhibited differentiation of keratinocytes. Psoriatic arthritis has a prevalence rate of 7% to 26% of the patients with psoriasis. Psoriasis is increasingly recognized as a systemic inflammatory process.
