Efficacy and safety of darunavir/ritonavir at 48 weeks in treatment-naïve, HIV-1-infected adolescents: results from a phase 2 open-label trial (DIONE).
Twice-daily darunavir/ritonavir is indicated in treatment-experienced children (≥3 years). This study assessed once-daily administration in treatment-naïve adolescents.. Phase 2, 48-week, open-label, single-arm study evaluating pharmacokinetics, safety and efficacy of once-daily darunavir/ritonavir 800/100 mg in treatment-naïve, HIV-1-infected adolescents (≥12 to <18 years, ≥40 kg) with zidovudine/lamivudine or abacavir/lamivudine.. Twelve patients (67% female; median 14.4 years) were enrolled. After 24 and 48 weeks, respectively, 11 of 12 (92%) and 10 of 12 (83%) patients achieved viral load <50 copies/mL (intent-to-treat time-to-loss of virologic response); all had ≥1 log10 drop in viral load versus baseline. Median CD4 cell count increased by 175 and 221 cells/mm (intent-to-treat-noncompleter = failure) after 24 and 48 weeks, respectively. Eighty-three percent of patients were adherent to darunavir/ritonavir. One patient was never suppressed and 1 patient rebounded. No patients developed darunavir resistance-associated mutations or lost phenotypic susceptibility to any commercially available protease inhibitor or any background nucleoside reverse transcriptase inhibitor. Eleven patients (92%) reported ≥1 adverse event (AE), considered in 2 patients to be at least possibly related to darunavir (gastrointestinal-related events and dizziness). Four patients had ≥1 serious AE. Three patients reported ≥1 grade 3/4 AE; no serious or grade 3/4 AEs were considered darunavir related. No patients discontinued because of AEs.. Over 48 weeks, once-daily darunavir/ritonavir 800/100 mg plus NRTIs was effective and well-tolerated for treatment of HIV-1-infected, antiretroviral-naïve adolescents (≥12 to <18 years). These findings support use of once-daily darunavir/ritonavir 800/100 mg in this population.

Severe abacavir hypersensitivity reaction in a patient with human immunodeficiency virus infection: a case report.
Abacavir is a nucleoside reverse transcriptase inhibitor that is used as a component of the antiretroviral treatment regimen in the management of the human immunodeficiency virus for both adults and children. It is efficacious, but its use may be limited by a hypersensitivity reaction linked with the HLA-B*57:01 genotype. HLA-B*57:01 has been reported to be rare in African populations. Because of the nature of its presentation, abacavir hypersensitivity is prone to late diagnosis and treatment, especially in settings where HLA-B*57:01 genotyping is not routinely done.. We report a case of a severe hypersensitivity reaction in a 44-year-old Kenyan female living with the human immunodeficiency virus and on abacavir-containing antiretroviral therapy. The patient presented to the hospital after recurrent treatment for a throat infection with complaints of fever, headache, throat ache, vomiting, and a generalized rash. Laboratory results evidenced raised aminotransferases, for which she was advised to stop the antiretrovirals that she had recently been started on. The regimen consisted of abacavir, lamivudine, and dolutegravir. She responded well to treatment but was readmitted a day after discharge with vomiting, severe abdominal pains, diarrhea, and hypotension. Her symptoms disappeared upon admission, but she was readmitted again a few hours after discharge in a hysterical state with burning chest pain and chills. Suspecting abacavir hypersensitivity, upon interrogation she reported that she had taken the abacavir-containing antiretrovirals shortly before she was taken ill. A sample for HLA-B*57:01 was taken and tested positive. Her antiretroviral regimen was substituted to tenofovir, lamivudine, and dolutegravir, and on subsequent follow-up she has been well.. Clinicians should always be cognizant of this adverse reaction whenever they initiate an abacavir-containing therapy. We would recommend that studies be done in our setting to verify the prevalence of HLA-B*57:01.
