RESUMEN

UNLABELLED: Mericitabine is a selective nucleoside analog inhibitor of the hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase, with activity across all HCV genotypes. Treatment-naïve patients infected with HCV genotype 1 or 4 were randomized to 24 weeks of double-blind treatment with either mericitabine 1,000 mg (N = 81) or placebo (N = 85) twice-daily (BID) in combination with pegylated interferon alpha-2a (Peg-IFNα-2a)/ribavirin (RBV). Patients randomized to mericitabine with HCV RNA <15 IU/mL from week 4 to 22 (extended rapid virologic response; eRVR) stopped all treatment at week 24; all other patients continued Peg-IFNα-2a/RBV to complete 48 weeks of treatment. The primary efficacy endpoint was sustained virologic response (SVR; HCV RNA <15 IU/mL after 24 weeks of treatment-free follow-up). SVR was achieved in 56.8% (95% confidence interval [CI]: 45.9-67.0) of mericitabine-treated patients and 36.5% (95% CI: 27.0-47.1) of placebo-treated patients (Δ = 20.3%; 95% CI 5.5-35.2). SVR rates were higher in mericitabine- than placebo-treated patients when subdivided by IL28B genotype (CC, 77.8% versus 56.0%; non-CC, 44.1% versus 16.2%) and hepatic fibrosis (noncirrhotic, 63.3% versus 41.9%; cirrhotic, 38.1% versus 21.7%). Overall relapse rates were 27.7% and 32.0% in mericitabine- and placebo-treated patients, respectively. No evidence of NS5B S282T-variant virus or phenotypic resistance to mericitabine was observed in the one patient who experienced partial response. No S282T variants were detected in any baseline samples. The safety profile of mericitabine was similar to that of, and fewer patients in the mericitabine than in the placebo group discontinued treatment for safety reasons. CONCLUSION: A 24-week response-guided combination regimen of mericitabine 1,000 mg BID plus Peg-IFNα-2a/RBV is well tolerated and more effective than a standard 48-week course of Peg-IFNα-2a/RBV.

RESUMEN

BACKGROUND & AIMS: PROPHESYS is a large, multinational, non-interventional prospective cohort study of chronic hepatitis C patients treated with peginterferon alfa/ribavirin. This subanalysis assesses rates of premature treatment discontinuation stratified by on-treatment virological response (VR). METHODS: This PROPHESYS subanalysis is restricted to treatment-naive, hepatitis C virus (HCV) genotype (G)1/2/3 mono-infected patients who received peginterferon alfa-2a (40KD)/ribavirin with intended treatment duration of 48 (G1) or 24 weeks (G2/3). Early virological responses were classified into four mutually exclusive categories [rapid VR (RVR), complete early VR (cEVR), partial EVR (pEVR), no RVR/EVR], using standard criteria. RESULTS: The likelihood for shortening treatment owing to good efficacy was highest among patients with an RVR and HCV RNA≤400 000 IU/ml (G1 10.0%; G2/3 5.8%) whereas for poor efficacy, it was highest in G1 non-RVR/EVR patients with HCV RNA>400 000 IU/ml (56.6%). Factors significantly associated with early treatment discontinuation as a result of good efficacy in G1 patients included RVR vs. no RVR/EVR and, at baseline, lower HCV RNA, lower FIB-4 score, HCV infection via injection drug use. For G2/3 patients, factors included lower baseline HCV RNA and G2 vs. G3 infection. Most patients started with the recommended peginterferon alfa-2a dose, but a high proportion received a higher-than-recommended ribavirin dose. CONCLUSIONS: Despite international guidelines, few physicians used early viral kinetics to abbreviate treatment. Therefore, relatively few patients with an RVR and low baseline HCV RNA abbreviated treatment. In addition, there were deviations in ribavirin starting doses, suggesting that physicians tailor treatment according to local guidelines or previous experience.

RESUMEN

Oritavancin is a new antibiotic for the treatment of serious infections with Gram-positive bacteria. It has been shown to be effective against methicillin-susceptible and -resistant Staphylococcus aureus as well as enterococci. With a terminal half-life of 393 hours, oritavancin lends itself to a convenient and potentially cost-effective single-dose regimen. The single-dose regimen is currently being evaluated in pivotal phase 3 studies. This unique property provides an opportunity to assure consistent, effective, and safe treatment for serious infections while reducing the costs of care through the elimination of multiple infusions, reduced medical care staff, shorter hospital stays, and avoidance of hospital-acquired infections. These features seem ideal for the use of oritavancin in the outpatient management of serious infections. The impact that oritavancin will have on outpatient therapy is unclear. Current models will need to change with only a single infusion. Physician monitoring of the infection and underlying diseases may not be as frequent despite the need for close follow-up and frequent evaluations. There will be less need for a team of outpatient infusion specialists. Outpatient therapy will be compensated less without multiple infusions. With the possibility of fewer physician and other medical visits, there will be more responsibility for the patient and family and a reliance on patients to care for themselves. Although oritavancin offers tremendous theoretical advantages in the outpatient treatment of serious infections, care should be taken to assure the quality of care through changes in reimbursement, patient education, and development of systems to monitor care and outcomes.

RESUMEN

BACKGROUND & AIMS: The current standard of care for patients with chronic hepatitis C virus (HCV) genotype 1 is once-weekly pegylated interferon-α (Peg-IFNα) plus daily ribavirin for 48 weeks. We evaluated the efficacy/safety of albinterferon alfa-2b (albIFN), a novel, long-acting, genetic fusion polypeptide of albumin and IFNα-2b. METHODS: In the phase 3 ACHIEVE-1 trial, 1331 patients were assigned equally to 3 open-label, 48-week treatment groups: Peg-IFNα-2a 180 µg every week, or albIFN 900 or 1200 µg every 2 weeks administered subcutaneously, with weight-based oral ribavirin 1000-1200 mg/day. During the study, the data monitoring committee recommended dose modification for all patients receiving albIFN 1200 µg to 900 µg because of increased pulmonary adverse events (AEs) in the 1200-µg arms of both ACHIEVE studies. Main outcome measure was sustained virologic response (SVR; undetectable serum HCV RNA at week 72). RESULTS: Intention-to-treat SVR rates were 51.0% (225/441), 48.2% (213/442), and 47.3% (208/440) with Peg-IFNα-2a, and albIFN 900 and 1200 µg, respectively. The primary objective of showing noninferiority of albIFN 900 µg (P < .001) and 1200 µg (P = .003) vs Peg-IFNα-2a for SVR was achieved. Multivariate modeling indicated consistency of treatment effect across subgroups. Serious/severe AE rates were 23.1%, 24.0%, 28.2%; treatment discontinuation rates because of AEs were 4.1%, 10.4%, 10.0%; discontinuation rates because of respiratory AEs were 0%, 0.9%, 1.6%; with Peg-IFNα-2a, and albIFN 900 and 1200 µg, respectively. Hematologic abnormality rates were comparable across the Peg-IFNα-2a and albIFN 900-µg groups. CONCLUSIONS: albIFN 900 µg every 2 weeks showed comparable efficacy, with similar serious/severe AE rates, although with a higher discontinuation rate, vs Peg-IFNα-2a in patients with chronic HCV genotype 1.

RESUMEN

Private practice physicians in Hawaii were surveyed to better understand their impressions of different insurance plans and their willingness to care for patients with those plans. Physician experiences and perspectives were investigated in regard to reimbursement, formulary limitations, pre-authorizations, specialty referrals, responsiveness to problems, and patient knowledge of their plans. The willingness of physicians to accept new patients from specific insurance company programs clearly correlated with the difficulties and limitations physicians perceive in working with the companies (p<0.0012). Survey results indicate that providers in private practice were much more likely to accept University Health Alliance (UHA) and Hawaii Medical Services Association (HMSA) Commercial insurance than Aloha Care Advantage and Aloha Quest. This was likely related to the more favorable impressions of the services, payments, and lower administrative burden offered by those companies compared with others.

RESUMEN

The evolution of methicillin-resistant and vancomycin-resistant Staphylococcus aureus has demanded serious review of antimicrobial use and development of new agents and revised approaches to prevent and overcome drug resistance. Depending on local conditions and patient risk factors, empirical therapy of suspected S. aureus infection may require coverage of drug-resistant organisms with newer agents and novel antibiotic combinations. The question of treatment with inappropriate antibiotics raises grave concerns with regard to methicillin-resistant S. aureus selection, overgrowth, and increased virulence. Several strategies to reduce the nosocomial burden of resistance are suggested, including shortened hospital stays and outpatient parenteral antimicrobial therapy of the most serious infections.

RESUMEN

OBJECTIVE: To identify apparent adverse effects of treatment of chronic hepatitis C and their relationship to sustained virologic response (SVR). METHODS: A retrospective study was conducted of all Hepatitis C virus (HCV)-infected patients treated with pegylated interferon and ribavirin in an academic ambulatory infectious disease practice. Clinical and laboratory characteristics were compared between patients with SVR and without SVR. RESULTS: Fifty-four patients completed therapy with the overall SVR rate of 76%. SVR was associated with genotype non-1 (P=0.01), weight loss more than 5 kilograms (P=0.04), end of treatment leukopenia (P=0.02) and thrombocytopenia (P=0.05). In multivariate analysis, SVR was significant associated with HCV genotype non-1 (Adjusted Odd Ratio [AOR] 15.22; CI 1.55 to 149.72; P=0.02), weight loss more than 5 kilograms, (AOR 5.74; CI 1.24 to 26.32; P=0.04), and end of treatment white blood cell count level less than 3 X 10(3) cells/microl (AOR 9.09; CI 1.59 to 52.63; P=0.02). Thrombocytopenia was not significant after adjustment. Other factors including age, gender, ethnicity, injection drug use, viral load, anemia, alanine transaminase level, and liver histology did not reach statistical significance. CONCLUSION: Besides non-1 genotype, SVR was found to be independently associated with weight loss during therapy, and leukopenia at the end of HCV treatment. These correlations suggest continuation of therapy despite adverse effects, may be of benefit.

RESUMEN

OBJECTIVES: To identify the risk factors for community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) cellulitis. METHODS: A review of risk factors for CA-MRSA skin and soft tissue infection in previously published literature was first performed. A retrospective cohort study was then conducted in a teaching ambulatory-care clinic of a tertiary medical center in Honolulu, Hawaii. RESULTS: Of 137 cases with cellulitis diagnosed from January 2005 to December 2007, MRSA was recovered from 85 (62%) of patients who presented with either abscesses or skin ulcers. The recovery of MRSA was significantly associated with obesity (p=0.01), presence of abscesses (p=0.01), and lesions involving the head and neck (p=0.04). Independent risk factors by multivariate logistic regression analysis included the presence of abscesses [adjusted odds ratio (aOR) 2.72; 95% confidence interval (CI) 1.27-5.83; p=0.01] and obesity (aOR 2.33; 95%; CI 1.10-4.97; p%0.03). Patients with CA-MRSA were less likely to receive an appropriate antibiotic (p=0.04) and were more likely to require antibiotic change at evaluation in one week (p=0.04) compared with patients infected with non-MRSA bacteria. CONCLUSIONS: The presence of abscesses and obesity were significantly associated with CA-MRSA cellulitis. Empiric therapy with antibiotics active against MRSA should be guided by these risk factors.

RESUMEN

A field study with follow up investigations sought to: 1. determine whether cold packs (over-the-counter symptomtic treatments), coupled with in-office education, improve antibiotic-related knowledge, attitudes and behaviors more than in-office education alone in patient populations with high percentages of Asian Americans and Hawaiian/Pacific Islanders; 2. identify possible reasons for intervention outcomes as described by physicians who participated in the field study; and 3. explore potential future directions based on a large sample survey of physicians in the field study's highly ethnic county. The intervention resulted in a pre- to post-consultation decrease in perceived need for and an increase in knowledge about antibiotic risks but had no impact on frequency of reported receipt of an antibiotic prescription. Unexpectedly, in-office education alone was more effective in increasing knowledge than in-office education plus the cold pack. In-depth interviews of field study physicians and a large scale physician survey suggest that cold pack interventions targeting patient populations with high percentages of Asian Americans and Hawaiian/Pacific Islanders may be more likely to succeed if accompanied by mass public education regarding risks and physician training regarding effective ways to talk to patients. Use of in-office education with cold packs alone may not achieve desired results.

RESUMEN

A microbiological algorithm has been developed to analyze beach water samples for the determination of viable colony forming units (CFU) of Staphylococcus aureus (S. aureus). Membrane filtration enumeration of S. aureus from recreational beach waters using the chromogenic media CHROMagar SA alone yields a positive predictive value (PPV) of 70%. Presumptive CHROMagar SA colonies were confirmed as S. aureus by 24-hour tube coagulase test. Combined, these two tests yield a PPV of 100%. This algorithm enables accurate quantitation of S. aureus in seawater in 72 hours and could support risk-prediction processes for recreational waters. A more rapid protocol, utilizing a 4-hour tube coagulase confirmatory test, enables a 48-hour turnaround time with a modest false negative rate of less than 10%.

RESUMEN

BACKGROUND: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has been increasingly reported over the past decade, including in Asian/Pacific Islanders (A/PIs). METHODS: We conducted ethnographic interviews in O'ahu and Kaua'i, Hawai'i, with 10 Asian/Pacific Islanders identified as having a history of CA-MRSA infections. RESULTS: Most (7/10) thought skin infections were not a new problem in Hawai'i. Most (8/9) attempted to self-treat the infection prior to seeking medical care with a range of home remedies and store- bought solutions. Most respondents did not initially comprehend the severity of their infection and only sought medical treatment after concern from family, unbearable pain, and/or other symptoms of illness. CONCLUSION: Clinicians should be aware of the reportedly frequent use of home remedies by this population, as it may potentially contribute to interactions when treatments are combined. If clinicians and public health professionals do not address perceptions and misperceptions of how MRSA is acquired, it will be very difficult to prevent infection, and may also delay individuals from seeking treatment.

RESUMEN

This publication contains information from a conference titled "Individual Perspectives on the Silent Epidemic of Viral Hepatitis in Hawai'i" held in October of 2007 with updates and additional contributions from annual conferences in 2008 and 2009. These conferences were sponsored by the Hepatitis Support Network of Hawai'i and held in Honolulu, Hawai'i at the Queen's Conference Center. The primary objectives of the conferences have been to heighten awareness of viral hepatitis in Hawai'i and to bring together health care professionals to learn about these infections and to help them respond to the challenges they bring to the people of Hawai'i. The initial conference was oriented to present the unique and individual perspectives of patients, physicians, and other healthcare providers specific to the complex issues of hepatitis in an effort to help them understand their role in the context of others and to develop a team approach in responding to this epidemic.

RESUMEN

BACKGROUND: Alternative therapies for Staphylococcus aureus bacteremia and endocarditis are needed. METHODS: We randomly assigned 124 patients with S. aureus bacteremia with or without endocarditis to receive 6 mg of daptomycin intravenously per kilogram of body weight daily and 122 to receive initial low-dose gentamicin plus either an antistaphylococcal penicillin or vancomycin. The primary efficacy end point was treatment success 42 days after the end of therapy. RESULTS: Forty-two days after the end of therapy in the modified intention-to-treat analysis, a successful outcome was documented for 53 of 120 patients who received daptomycin as compared with 48 of 115 patients who received standard therapy (44.2 percent vs. 41.7 percent; absolute difference, 2.4 percent; 95 percent confidence interval, -10.2 to 15.1 percent). Our results met prespecified criteria for the noninferiority of daptomycin. The success rates were similar in subgroups of patients with complicated bacteremia, right-sided endocarditis, and methicillin-resistant S. aureus. Daptomycin therapy was associated with a higher rate of microbiologic failure than was standard therapy (19 vs. 11 patients, P=0.17). In 6 of the 19 patients with microbiologic failure in the daptomycin group, isolates with reduced susceptibility to daptomycin emerged; similarly, a reduced susceptibility to vancomycin was noted in isolates from patients treated with vancomycin. As compared with daptomycin therapy, standard therapy was associated with a nonsignificantly higher rate of adverse events that led to treatment failure due to the discontinuation of therapy (17 vs. 8, P=0.06). Clinically significant renal dysfunction occurred in 11.0 percent of patients who received daptomycin and in 26.3 percent of patients who received standard therapy (P=0.004). CONCLUSIONS: Daptomycin (6 mg per kilogram daily) is not inferior to standard therapy for S. aureus bacteremia and right-sided endocarditis. (ClinicalTrials.gov number, NCT00093067 [ClinicalTrials.gov].).

RESUMEN

Immune reconstitution inflammatory syndrome (IRIS) is an acute symptomatic expression of a latent infection during the recovery of the immune system usually as a response to antiretroviral therapy (ART). Opportunistic infections can trigger IRIS. Hansen's disease is an infection caused by Mycobacterium leprae (M. leprae). There have been a limited number of case reports reporting the presentation of the co-infection of HIV and M. leprae. We report an unique case of IRIS in a patient co-infected with HIV and M. leprae presenting as an exacerbation of his Hansen's Disease where the patient's skin lesions progressed from borderline tuberculoid to lepromatous leprosy following ART administration.

RESUMEN

It is estimated that as many as 21,000 people in the state of Hawai'i may be infected with HCV Most of those infected with viral hepatitis are unaware they are infected. Complications from viral hepatitis include liver cirrhosis and hepatocellular carcinoma. Hawai'i has the highest incidence of hepatocellular carcinoma in the United States. In 2003 there were over 6000 homeless and over 155,000 people at-risk of becoming homeless living in the state of Hawai'i. Risk factors for hepatitis, such as drug use, tattoos, sexual contact, and sharing of personal hygiene equipment are more prevalent in the homeless population. To determine the incidence of hepatitis B and C among a population of homeless individuals, a health fair was held at a Honolulu area homeless shelter with approximately 200 residents. The incidence of hepatitis B and C was determined by anti-HCV and HBsAg blood tests. A survey was also conducted regarding risk factors and basic demographics. Fifty-nine homeless adults volunteered for testing and took the survey. Thirty-one (52%) volunteers were born in Micronesia, twenty-four (41%) were born in the United States, two (3%) were born in Samoa, one (2%) was born in the Philippines, and one (2%) was born in the Marshall Islands. Forty adults were tested for Hepatitis C antibody, three of which tested positive. The primary risk factor among this group was jail time (100%), followed by illegal drug injection (67%), tattoos (67%), ear/body piercing (67%), snorting drugs (33%), blood transfusions (33%), and a sex partner with hepatitis (33%). Forty adults were also tested for HBsAg, One of which tested positive. This was a recent immigrant from Micronesia. Homeless people in Hawai'i are more likely to have hepatitis B or C because risk factors are common among this population. Additionally a large proportion of Hawai'i's homeless people come from the Pacific Islands, where the prevalence of hepatitis B is one of the highest in the world. In addition there are significant risks of hepatitis spread among the homeless and into the general population as many homeless do not realize they are infected. The health fair approach was an effective means for screening homeless people for hepatitis B and C. Our preliminary information suggests homeless shelters may be a good place for education, screening, and possibly interventions as well.

RESUMEN

BACKGROUND: Adherence to chronic hepatitis C (CHC) treatment may be particularly challenging in methadone maintenance patients. We assessed the safety, tolerability, and efficacy of peginterferon alfa-2a/ribavirin treatment in methadone maintenance patients previously untreated for CHC. METHODS: Patients were randomized 1:1 to direct observed therapy (DOT) or self-administration (SA) of peginterferon alfa-2a. DOT patients were seen weekly at methadone clinics; SA patients were seen less frequently, only at investigative sites. Genotype 1-infected patients were treated for 48 wk with peginterferon alfa-2a (180 microg/wk)/ribavirin (1,000/1,200 mg/day); genotypes 2- and 3-infected patients were treated for 24 wk with peginterferon alfa-2a (180 microg/wk)/ribavirin (800 mg/day). RESULTS: Based on defined efficacy stopping rules, 77% (37/48) completed their targeted length of treatment, and 44% (21/48) achieved sustained virologic response (SVR). Two DOT and 3 SA patients were withdrawn for safety reasons and 6 and 9, respectively, for nonsafety reasons. Over 60% and 50% of each group were >80% compliant with the planned cumulative doses of peginterferon alfa-2a and ribavirin, respectively, and over 60% with overall treatment duration. SVR rates were 54% (13/24) for DOT and 33% (8/24) for SA; 23% (3/13) and 38% (6/16), respectively, for genotype 1 and 91% (10/11) and 25% (2/8), respectively, for genotypes 2 and 3. Stepwise logistic regression analysis, showed that DOT (vs SA; OR 3.27, 95% CI 0.90-11.91, P = 0.073) and Caucasian race (vs Other; OR 13.31, 95% CI 1.42-124.71, P = 0.023) were predictors of SVR. CONCLUSION: Peginterferon alfa-2a/ribavirin can be used safely and successfully in CHC patients receiving methadone maintenance.

RESUMEN

PURPOSE: To evaluate potential cost savings, trial data were used to determine the clinical outcomes for i.v. ertapenem given once daily and i.v. piperacillin-tazobactam given every six hours daily in treating diabetic foot infections. METHODS: A cost-minimization analysis (CMA) was conducted on the drug-dosing data of the subset of patients enrolled in a recent double-blind randomized trial who were treated solely as inpatients and were clinically evaluable at fi nal assessment (n = 99). Cost per dose was calculated from (a) average hospital acquisition price per dose for ertapenem ($40.52) or piperacillin-tazobactam ($13.58), (b) average U.S. wages and benefits for labor, based on nine published time-and-motion studies of i.v. antibiotic preparation and administration ($3.10), and (c) consumable supplies, using a 40% discount off the manufacturer list price ($2.90). For each patient, the actual number of antibiotic doses given was multiplied by total cost per dose. RESULTS: There were no significant differences between antibiotic groups with respect to patient demographics, percentage with a severe wound, and mean days of i.v. therapy. Compared with piperacillin-tazobactam, patients treated with ertapenem received significantly fewer mean doses (25.5 versus 7.5; p < 0.0001) and lower antibiotic-related costs ($502.76 versus $355.55, respectively; p < 0.001). The $147.21 difference between groups accounts for approximately 3% of total hospital Medicare reimbursements for these infections. CONCLUSION: A CMA of treatment of diabetic foot infections showed that, compared with piperacillin-tazobactam given four times daily i.v., ertapenem given once daily i.v. was associated with lower drug acquisition and supply costs and less time and labor devoted to preparation and administration of i.v. therapy.

RESUMEN

We report a case of a 29-year-old man with schizoaffective disorder in which diabetes mellitus and hypertriglyceridemia developed with quetiapine (Seroquels). We reviewed the literature on the relationship between antipsychotic therapy and development of metabolic disorders and found serious concerns. This case demonstrates the importance of a careful monitoring of glucose and other metabolic parameters in patients receiving atypical antipsychotics.

RESUMEN

Hyperthyroidism has been described after highly active antiretroviral therapy for AIDS and has been attributed to late onset immune reconstitution. The team reports a young Polynesian man with AIDS who responded to highly active antiretroviraltherapy. However, 15 months after initiation of antiretroviral therapy, he was hospitalized for hypokalemic thyrotoxic periodic paralysis, an unusual manifestation of hyperthyroidism which typically occurs in young Asian males.

RESUMEN

Hepatitis B is frequent in the Philippines. A high rate of immigration to the United States has brought many Filipinos with infections who are asymptomatic yet will go on to develop liver cancer and cirrhosis unless diagnose and evaluated. Interventions are necessary to educate this ethnic community, identify those infected, and offer therapy. In an effort to reach this high risk population in Hawai'i an intervention program was designed to address the silent epidemic of hepatitis. Ethnic barriers were crossed through involvement of trusted, key stakeholders and individuals within the Filipino health care and church communities, along with groups that had joint missions to address viral hepatitis. After extensive planning and meetings with faith-based organizations and health care providers in the Filipino community, it was decided to hold a community health fair in the Filipino community to provide culturally appropriate health information and services. More than 500 individuals attended the health fair; 167 participated in a survey and were tested for hepatitis B. Significant knowledge gaps were found in relation to risk factors, prevention strategies, and transmission. Five individuals tested positive; all were immigrants and did not know of their disease. The objective to educate people and test them for hepatitis was successful through utilizing ethnic community leaders, religious organizations, health care professionals, and a collaborative health fair.
