Randomized, Placebo-Controlled Trial of Targeting Neuroinflammation with Ibudilast to Treat Methamphetamine Use Disorder

AbstractMethamphetamine (MA) triggers neuroinflammation and medications that counteract MA-induced neuroinflammation may reduce MA-induced neurodegeneration and improve neurocognition and treatment outcomes in MA use disorder. We performed a randomized, placebo-controlled trial to determine the safety and efficacy of ibudilast (IBUD), a phosphodiesterase inhibitor that reduces neuroinflammation, for the treatment of MA use disorder. Treatment-seeking volunteers with MA use disorder were randomly assigned to receive 12  weeks of IBUD 50 mg twice daily (N = 64) or placebo (N = 61) with medication management counseling. Participants visited the outpatient research clinic twice weekly to provide urine specimens for drug screens and undergo study assessments. The primary outcome was end of treatment MA-abstinence (EOTA) during weeks 11 and 12 of treatment. Serum IBUID levels were measured for IBUD participants during week 3 of treatment. There was no difference in EOTA for IBUD (14%) versus placebo (16%,p >  0.05). There was no correlation between serum IBUD levels and MA use during treatment and mean IBUD levels for participants with (mean = 51.3, SD = 20.3) and without (mean = 54.7, SD = 33.0,p = 0.70) EOTA. IBUD was well tolerated. IBUD did not facilitate MA abstinence in this outpatient trial. Whether targeting neuroinflammation, either with IBUD in othe...

CONCLUSION: Prevalence of antibiotic use was high not only versus other hospitals in the region but globally including Africa, coupled with significant evidence of sub-optimal prescribing. Swift action is needed to improve future prescribing to reduce AMR. One or two areas should initially be targeted for quality improvement including development of local guidelines, documentation of antibiotic indications and/or stop/review dates.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...

Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...
