What is the comparative tolerability and safety of peginterferon alfa-2a plus ribavirin versus peginterferon alfa-2b plus ribavirin for treatment of chronic hepatitis C virus infection? Does the comparative effectiveness or tolerability and safety of peginterferon alfa-2a plus ribavirin versus peginterferon alfa-2b plus ribavirin vary in patient subgroups defined by demographics (age, racial groups, gender, genotype, markers of disease severity), use of other medications, or presence of co-morbidities (such as HIV infection)? Pegylated interferons for hepatitis C Page 8 of 65 Final Report Drug Effectiveness Review Project METHODS Literature Search To identify articles relevant to each key question, we searched Medline (1966 to July Week 4 2006), the Cochrane Central Register of Controlled Trials (3rd Quarter 2006), the Cochrane Database of Systematic Reviews (2nd Quarter 2006), and the Database of Abstracts of Reviews of Effects (3rd Quarter 2006) (See Appendix A for search strategies). We also searched reference lists of included review articles for additional citations. Pharmaceutical manufacturers were invited to submit dossiers, including citations. All citations were imported into an electronic database (Endnote 9. Study Selection All citations were reviewed for inclusion using the criteria shown in Table 3. Full-text articles of potentially relevant citations were retrieved and inclusion criteria were re-applied. Title and abstract review was conducted by two independent reviewers (Carson and Care); review of full-text articles was conducted by one reviewer (Carson) and checked by a second (Chou). Study inclusion criteria Populations • Non-pregnant adult outpatients with chronic Hepatitis C infection Subgroups include: • HIV-infected persons • Non-responders or relapsers (including re-treatment) • Based on gender, race, or age • Based on genotype • Based on viral load • Based on liver function test abnormalities • Based on degree of fibrosis, inflammation, or cirrhosis on liver biopsy • Based on other co-morbid conditions, including obesity, addiction, psychiatric illness Treatments • Pegylated interferon alfa-2a plus ribavirin • Pegylated interferon alfa-2b plus ribavirin Effectiveness outcomes • Sustained virologic response (SVR) • Normalization of liver enzyme abnormalities (sustained biochemical response, or SBR) • Improvement in inflammation or fibrosis on liver biopsy • Cirrhosis • Hepatocellular carcinoma • Need for liver transplant • Quality of life Pegylated interferons for hepatitis C Page 9 of 65 Final Report Drug Effectiveness Review Project • Mortality • Early virologic response (only for head-to-head trials) Safety outcomes • Overall adverse effects • Withdrawals due to adverse effects • Serious adverse events (including depression, suicidality) • Specific adverse events (including myalgias, flu-like symptoms, fevers, chills, neutropenia, dose reduction) Study designs • For assessment of effectiveness in general, controlled clinical trials and good-quality systematic reviews were included. We defined a sustained virologic response (SVR) as the absence of detectable HCV RNA 21 in the serum six months after the end of a course of therapy. SVR is the best short-term predictor of long-term virologic remission rates and is associated with improvements in fibrosis 22 and inflammation. End-of-treatment response (ETR) was defined as no detectable virus at the end of a course of therapy. We did not consider ETR a primary outcome since it is not as reliable as SVR for predicting long-term remission. Some trials also measure early virologic response (EVR), which is usually defined as absence of detectable HCV RNA in serum or >2. Although assessing EVR is helpful for determining whether to complete a full course of therapy (patients without an EVR are unlikely to achieve an SVR), it is less accurate than ETR for predicting long-term remission. We included head-to-head trials reporting EVR because no head-to-head trials reporting longer- term outcomes are currently available. We defined a sustained biochemical response (SBR) as normalization of liver transaminases six months after the end of a course of therapy. Some trials also report end-of- treatment biochemical response. Definitions for histological response are less standardized than definitions for reporting virologic outcomes, however traditionally a histologic response has been defined as a 2-point or greater decrease in the inflammatory score or fibrosis score, or a 1-point 21 decrease in the fibrosis score. Because dual therapy with pegylated interferon has only been available since 2001 and assessment of effects on rates of cirrhosis, hepatocellular cancer, need for liver transplant, and mortality would require studies with extended (a decade or more) follow-up, we believed studies evaluating these outcomes would probably not be available. However, we did search for studies reporting these important clinical outcomes. We included non-randomized studies as well as randomized trials reporting adverse events (withdrawal due to adverse events, serious adverse events, overall adverse events, hematologic adverse events, flu-like symptoms, and depression) associated with dual therapy with pegylated interferon. Pegylated interferons for hepatitis C Page 10 of 65 Final Report Drug Effectiveness Review Project Data Abstraction The following data were abstracted from included trials: study design, setting, population characteristics (including sex, age, ethnicity, and HCV genotype), eligibility and exclusion criteria, and interventions (dose and duration); numbers screened, eligible, enrolled, and lost to follow-up; method of outcome ascertainment; and results for each outcome (including SVR, ETR, SBR, histological response rates, quality of life, other clinical outcomes, and adverse events). We recorded intention-to-treat results when available. Results were entered into a relational database (Microsoft Access 2003). Quality Assessment We assessed internal validity (quality) of controlled clinical trials using predefined 23 criteria adapted from those developed by the US Preventive Services Task Force and the 24 National Health Service Centre for Reviews and Dissemination (Appendix B).

Other manifestations of disseminated CMV infection are rare (15%) buy kamagra 50 mg amex, and can affect every organ 100mg kamagra sale. The lung (pneumonia) buy kamagra 50mg overnight delivery, esophagus (ulcers) 100 mg kamagra visa, colon (colitis) and CNS (encephalitis) are most frequently involved kamagra 100 mg online. The clinical signs of these CMV diseases depend on the organ affected. Diagnosis is often difficult and may only be possible on histology (Goodgame 1993). There is insufficient data on the treatment of these manifestations, so systemic therapies are usually chosen along with treatment for CMV retinitis (Whitley 1998). Newer studies have suggested that CMV infection plays a role in the pathogenesis of artery disease and that CMV-induced T cell immunopathology could contribute to HIV-associated atherosclerosis (Parrinello 2012, Sacre 2012). There is also an asso- ciation between CMV infection and altered immune reconstitution (Appay 2011, Wittkop 2013). Signs and symptoms Any visual impairment occurring peracutely or acutely, such as blurred vision or floaters – especially unilaterally – should prompt an immediate (same day, if possi- ble) ophthalmological examination of the patient. Once there is a black spot in the visual field, it will be permanent. Involvement of the posterior pole (zone 1 retinitis) accounts for approximately one half of incident visual acuity loss. Cataract and retinitis-related retinal detachment are also common causes of vision loss (Thorne 2006). All CMV treatment regimens can prevent progression of lesions, but not reverse them. Eye pain, burning, increased production of tears, and conjunctival irritation are not typical. However, many patients suffer from systemic symptoms such as fever and weight loss. Assessment of the usually peripheral, whitish exudates is dependent on the experience of the ophthalmologist. However, this can frequently be a problem, due to the rare occurrence of CMV retinitis nowadays. Unfortunately, incorrect diagnoses do happen and retina are lost. Therefore, if the primary ophthalmologist remains undecided, it is best to start with oral valgancy- clovir and transport the patient to a larger clinical center with ophthalmologists who are experienced in HIV. Furthermore, it is essential that the ophthalmologists receive information about the patient’s immune status. In cases of poor immune status and CD4 count less than 100/µl, chorioretinitis caused by Toxoplasma gondii is the most important differential diagnosis. CMV retinitis can almost be excluded at CD4 T cell Opportunistic Infections (OIs) 347 counts above 100/µl; other viral infections (HSV, VZV) or even neurosyphilis should then be considered. CMV lesions may also be confused with cotton wool spots, which are not rare in patients with high HIV viral load. Multiple small lesions without hemorrhage or exudates are almost always cotton wool spots, and almost never CMV retinitis. Bilateral involvement is also usually the exception. Vitritis is rare, except with immune reconstitution syndrome. CMV serology (IgG almost always positive, IgM variable) is seldom helpful for diagnosis. CMV PCR or a blood test for pp65 antigen to detect antibodies against a CMV-specific phosphoprotein may be more useful. CMV retinitis or a recurrence is unlikely with a negative PCR or pp65 result. The higher the levels of CMV viremia, the higher the risk of CMV disease.

Despite the impact of lipodystrophy syndrome on HIV management, little is known about the pathogenesis, its prevention, diag- nosis and treatment. Current data indicate a rather multifactorial pathogenesis where HIV infection, ART, and patient-related factors are all major contributors. The lack of a clear and easy definition reflects the clinical heterogeneity, limits a clear diagnosis and impairs the comparison of results among clinical studies. Therapeutic and pre- vention strategies have so far been of only limited clinical success, where avoiding the use of thymidine analogues appears to be most effective in avoiding peripheral fat loss. General recommendations include dietary changes and lifestyle modifica- tions, ART modification (replacing PIs with NNRTIs or replacing d4T and AZT with abacavir or tenofovir or switching to an NRTI-free regimen, e. Clinical manifestation Lipodystrophy was originally described as a condition characterized by regional or generalized loss of subcutaneous fat. Non-HIV-associated forms, such as congenital or familial partial lipodystrophy, have a very low prevalence. Generally, these forms are associated with complex metabolic abnormalities and are difficult to treat. The term “lipodystrophy syndrome” was introduced to describe a complex medical con- dition including an apparent abnormal fat redistribution and metabolic disturbances in HIV+ patients receiving protease inhibitor therapy (Carr 1998). Now, years after its first description, there is still no consensus on a case definition for lipodystrophy syndrome in HIV. Thus, the diagnosis of lipodystrophy in clinical practice often relies on a more individual interpretation than on an evaluated classification. Finally, changes in fat distribution have to be considered as being part of a rather dynamic process. In most cases, peripheral lipoatrophy is clinically diagnosed when signifi- cant fat loss of about 30% has already occurred. HIV-associated lipodystrophy includes both clinical and metabolic alterations. The most prominent clinical sign is a loss of subcutaneous fat (lipoatrophy) in the face (periorbital, temporal), limbs, and buttocks. Prospective studies in patients on thymi- dine analogues have demonstrated an initial increase in limb fat during the first months of therapy, followed by a progressive decline over the ensuing years (Mallon 2003), which is mostly persistent (Grunfeld 2010). Peripheral fat loss can be accom- panied by an accumulation of visceral fat, which can cause mild gastrointestinal symptoms. Initially truncal fat increases on therapy and then remains stable (Mallon 2003). Visceral obesity, as a singular feature of abnormal fat redistribution, appears to occur in only a minority of patients. Fat accumulation may also be found as dor- socervical fat pads (buffalo hump) or within the muscle and the liver. Female HIV+ patients sometimes complain about painful breast enlargement, attributed to the lipodystrophy syndrome. Whether gynecomastia in male patients is a component of the syndrome remains unclear. There is now accumulating evidence that the major clinical components – lipoatrophy, central adiposity and the combination of both – result from different pathogenetic developmental processes. The risk of the syndrome increases with the duration of treatment, the age of the 292 ART patient and the level of immunodeficiency. Children can be affected, like adults, with clinical fat redistribution shortly after initiation or change of ART. The evolution of the individual clinical components of the lipodystrophy syndrome is variable. The nucleoside analogue linked most strongly to lipoatrophy is d4T, particularly when used in combination with ddI. Tenofovir combined with 3TC and efavirenz is associated with less loss of limb fat than d4T in a similar combination in therapy- naïve HIV+ patients (Gallant 2004). Hyperlipidemia is a frequent side effect of antiretroviral therapies, especially those that include PIs (Nduka 2015). Newer drugs such as dolutegravir, elvitegravir, ralte- gravir, maraviroc, second-generation NNRTIs such as rilpivirine do not disadvan- tages in lipid metabolism and may therefore offer a favorable safety profile in patients at risk (Curtis 2014, Quercia 2015).
