After treatment for primary or secondary syphilis, the HIV-infected patients responded less well serologically than the patients without HIV infection, but clinically defined failure was uncommon in both groups. Enhanced treatment with amoxicillin and probenecid did not improve the outcomes. Although T. pallidum was detected in cerebrospinal fluid before therapy in a quarter of the patients tested, such a finding did not predict treatment failure. The current recommendations for treating early syphilis appear adequate for most patients, whether or not they have HIV infection.
Nontargeted opt-out rapid HIV screening in the ED, vs diagnostic testing, was associated with identification of a modestly increased number of patients with new HIV diagnoses, most of whom were identified late in the course of disease.
This gp160 vaccine is safe and immunogenic in volunteer patients with early HIV infection. Although it is too early to know whether this approach will be clinically useful, further scientific and therapeutic evaluation of HIV-specific vaccine therapy is warranted. Similar vaccines may prove to be effective for other chronic infections.
The efficacy and toxicity of sodium stibogluconate (SSG) at a dosage of 20 mg/(kg.d) for either 20 days (for cutaneous disease) or 28 days (for visceral, mucosal, or viscerotropic disease) in the treatment of leishmaniasis is reported. Ninety-six U.S. Department of Defense health care beneficiaries with parasitologically confirmed leishmaniasis were prospectively followed for 1 year. One patient was infected with human immunodeficiency virus; otherwise, comorbidity was absent. Clinical cure occurred in 91% of 83 cases of cutaneous disease and 93% of 13 cases of visceral/viscerotropic disease. Adverse effects were common and necessitated interruption of treatment in 28% of cases, but they were generally reversible. These included arthralgias and myalgias (58%), pancreatitis (97%), transaminitis (67%), headache (22%), hematologic suppression (44%), and rash (9%). No subsequent mucosal leishmaniasis was identified, and there were no deaths attributable to SSG or leishmaniasis.
In select cases of multidrug-resistant HIV-1 infection, lamivudine contributes to suppression of HIV-1 replication, despite the presence of M184V mutations and lamivudine resistance.
A key factor to the successful treatment of HIV is good adherence to antiretroviral therapy (ART). We developed a pharmacist-managed adherence clinic and designed a study to assess the impact of the adherence interventions by measuring the proportion of patients with 95% or greater adherence to ART before and after referral to the program. HIV providers referred patients with adherence problems to a pharmacist-managed adherence clinic. Interventions included scheduled clinic visits with the HIV Clinical Pharmacist and monthly refill reminders from pharmacy staff members over a 6-month period. Those aged 18-75, prescribed an ART regimen for a minimum of 3 months, and who filled their medications exclusively at the clinic pharmacy were eligible for study participation. The Proportion of Days Covered (PDC) served as a surrogate marker of overall adherence. A total of 34 patients were referred to the pharmacy clinic for adherence counseling, of whom 28 enrolled in the study. The proportion of participants with 95% or greater adherence to their ART regimen increased from 7% at baseline to 32% postintervention (p = 0.01). A subanalysis of the PDC revealed an overall increase from a baseline adherence mean of 60% to 81% postintervention (p < 0.0001). There was a notable trend toward an increase in the proportion of participants with an undetectable HIV-1 viral load (58-73%, baseline and postintervention, respectively, p = 0.10), but no statistically significant improvement in CD4 cell count. Clinical pharmacy interventions improved overall adherence to ART regimens in these patients with HIV.
4 Abstract-A tropospheric ozone Differential Absorption Lidar 5 system, developed jointly by The University of Alabama in 6 Huntsville and the National Aeronautics and Space Adminis· 7 tratioD, is making regular observations of ozone vertical diss tributions between 1 and 8 km with two receivers under both 9 daytime and nighttime conditions using lasers at 285 and 291 run. 10 This paper describes the Udar system and analysis technique 11 with some measurement examples. An iterative aerosol correction I2 procedure reduces the retrieval error arising from differential 13 aerosol backscatter in the lower troposphere. -Lidar observations 14 with coincident ozonesonde flights demonstrate that the retrieval 15 accuracy ranges from better than 10% below 4 km to better 16 than 20% below 8 kin with 7S0·m vertical resolution and 10·min 17 temporal integration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
