Immunotherapy In recent years, in addition to ART, immunomodulatory treatment strategies have been investigated. Although repeatedly discussed as an alternative or supplement, these therapies lack proof of clinical benefit. An important example is the failure of the two large IL-2 studies (see below). Some approaches are nevertheless addressed here briefly (in alphabetic order). Corticosteroids do not stand the test of controlled studies. In ACTG 349, 24 patients were treated with 40 mg prednisone daily or not in a double-blind randomized design (Wallis 2003). After 8 weeks, there was a trend towards higher levels of CD4 T cells in the prednisone arm, but there were no effects on activation markers or apoptosis. Two patients on prednisone developed necrosis of the femoral head. This study should caution anyone before considering steroids for immunological reasons. Cyclosporin A (Sandimmune) – Immune activation may lead to increased HIV replication, and a treatment hypothesis has been to suppress the immune system in an attempt to slow down viral replication. This is the rationale behind studies inves- tigating the use of cyclosporin A, a drug normally used for prophylaxis of transplant rejection after allogenic organ transplantation. However, results of clinical trials have been disappointing. Cyclosporin A had no effect on CD4 or CD8 T cell count, nor on expression of activation markers (Calabrese 2002, Lederman 2006). This was not only the case in chronically but also in acutely infected patients (Miro 2009, Markowitz 2010). Cyclosporin A therefore probably has a limited future in HIV therapy. G-CSF (granulocyte colony-stimulating factor) is available as filgastrim (Neupogen), lenogastrim (Granocyte) and most recently as less expensive biosimilars (in Europe). It is also licensed for permanent neutropenia in advanced HIV infection to avoid bacterial infection. In a randomized study with 258 HIV-infected patients with CD4 T cells under 200/µl, the rate of severe neutropenia was 2% versus 22% in the control group after 24 weeks (Kuritzkes 1998). Incidence of bacterial infection was reduced by 31% and the number of inpatient days dropped by 45%. ART 2017/2018: The horizon and beyond 139 were seen. Patients with CMV retinitis showed a large survival benefit on G-CSF (Davidson 2002). Although severe neutropenia has become rare on ART, G-CSF can be useful, especially in chemotherapy, with interferon or other myelo-suppressive drugs such as valgancyclovir. GM-CSF (granulocyte macrophage colony-stimulating factor) is available as molgramostim (Leucomax) or sargramostim (Prokine). Three double-blind, randomized studies showed a slight effect on viral load (Angel 2000, Skowron 1999, Brites 2000). However, in one study in patients with uncontrolled infection, there was a slight increase of viremia (Jacobsen 2003). GM-CSF seems to prevent signifi- cant loss of CD4 T cells during treatment interruptions (Fagard 2003). Given the side effects and significant cost of GM-CSF, it cannot be recommended outside clinical studies. Hydroxyurea (HU, Litalir) is an old chemotherapeutic agent with relatively low toxicity still being used today in hematology (mostly in chronic myelogenous leukemia). It inhibits DNA synthesis via the ribonucleotide reductase, and leads to an intracellular shortage of deoxynucleotide triphosphates. A synergistic effect on HIV replication in combination with ddI was demonstrated in 1994 (Lori 1994). A Swiss study, in which 144 patients were treated with hydroxyurea (HU) or placebo plus d4T+ddI, attracted attention in 1998 (Rutschmann 1998). After 12 weeks, 54% (versus 28% in the placebo group) demonstrated a viral load below 200 copies/ml. Was this the discovery of a new cheaper option for HIV treatment?

Pediatric asthma 88 Ralston and colleagues compared levalbuterol to the combination of racemic albuterol plus ipratropium bromide in 140 children age 6 to 18 years seen in the emergency department with acute asthma in a fair-quality study sinemet 125mg line. For the study’s primary outcome of length of stay in the emergency department or the hospital (if admitted) generic sinemet 300 mg free shipping, the median value was comparable between the 2 study groups (P=0 sinemet 110mg mastercard. The groups were also comparable for the number of nebulization treatments in the emergency department and the time between treatments. Fewer patients were given adjunct medications (including steroids) in the levalbuterol group than in the albuterol- plus-ipratropium bromide group (P=0. Albuterol compared with albuterol plus ipratropium bromide Adult asthma 12 The Cochrane systematic review by Westby and colleagues was used as the basis for this drug comparison. This review examined the effectiveness of anticholinergic agents compared with placebo and compared with beta -agonists, or as adjuncts to beta -agonists. These authors2 2 searched multiple bibliographic databases up to August 2004 and identified 9 studies with follow-up greater than 24 hours involving 440 patients in comparing anticholinergic drug plus beta -agonist combination therapy with beta -agonist monotherapy. One of the studies examined2 2 CR terbutaline and 2 other studies did not provide sufficient data for inclusion in the reviewers’ meta-analysis. These reviewers noted heterogeneity across the remaining studies for follow-up intervals, dosing, and study design (parallel and crossover). They found no significant difference in any of the symptom scores between treatments. Overall there were fewer withdrawals with beta -agonist monotherapy. Two studies looked at the number of patients with exacerbations and2 found no significant differences between treatments. There was also little difference in adverse effects between the 2 treatments. In a good- quality trial of adults (89% African American) presenting to an emergency department with 84 acute asthma, Salo and colleagues randomized 66 patients to either albuterol 7. There was no significant difference in hospital admission rates between the combination therapy (25%) and albuterol monotherapy groups (16. The odds ratio for hospital admissions in the combination group was 1. Quick-relief medications for asthma Page 20 of 113 Final Report Update 1 Drug Effectiveness Review Project Pediatric asthma 9 The Cochrane review by McDonald and colleagues included studies of children using an anticholinergic drug for more than 1 week. One very small trial compared ipratropium bromide plus salbutamol with placebo plus salbutamol, both delivered by metered aerosol 4 times daily. A second trial compared ipratropium bromide plus fenoterol with placebo plus fenoterol delivered via nebulizer 3 times daily. Both trials failed to show any significant benefit with respect to symptom scores from the addition of anticholinergic drugs to beta -agonist monotherapy. In a fair-quality trial set in India, children age 5 to 15 years with mild to moderate acute exacerbation of asthma were randomized to either 4 actuations of ipratropium bromide (80 µg total) or placebo given with a metered dose inhaler using a spacer. All children were first given 4 actuations of salbutamol (400 mcg total) via a metered dose inhaler and spacer, then the study drug. Thirty minutes after treatment there was no significant difference between treatments in scores for wheezing or for use of accessory muscles. For both therapies, 3 doses were delivered by nebulizer at 20-minute intervals. Oral corticosteroids were administered to all children, and additional doses of salbutamol were administered for incomplete response. Follow-up by mail showed that the groups had similar rates of a “close secondary attack that required rescue medication” (9% with combination therapy and 21% with monotherapy). Data were available for 85% of randomized subjects, and “close” was not defined. Subgroup analyses based on age and severity “showed no statistically significant differences between the 2 groups at any time,” but it was unclear which outcomes were examined for these analyses. Both therapies were delivered by nebulization every 20 minutes for 3 doses. Oxygen was administered; there was no mention of corticosteroids. Dyspnea, wheeze, and accessory muscle scores decreased from baseline more with combination therapy than with monotherapy (between-group P<0. Hospitalization occurred in 1 patient in the combination therapy group and 4 subjects in monotherapy. Ipratropium bromide compared with ipratropium bromide plus albuterol Adult asthma 103 In a small, fair- to poor-quality trial in New Zealand, 36 adults with mild to moderate asthma using inhaled corticosteroids were randomized to 4 puffs three times daily of salbutamol 100 ® µg/ipratropium bromide 20 µg daily via a metered dose inhaler (Combivent ) or ipratropium ® bromide 20 µg 4 puffs 3 times daily (Atrovent ). Both groups used ipratropium bromide 40 Quick-relief medications for asthma Page 21 of 113 Final Report Update 1 Drug Effectiveness Review Project µg/puff for symptom relief. After 2 weeks of the assigned treatment drug (Phase 1), the inhaled steroids were withdrawn from both groups (Phase 2). Patients were then observed until one of the following predetermined criteria for loss of control of asthma were met: mean morning peak expiratory flow rates <90%, mean run-in values in 2 consecutive morning peak flow rates <80% of mean values during the run-in period; night wakening occurring 2 or more nights per week more often than during run-in; or distressing or intolerable symptoms.
