Persistent neutrophilic meningitis presents a diagnostic challenge, because the differential diagnosis is broad and includes atypical infectious causes. We describe case of persistent due to Aspergillus fumigatus in an immunocompetent man who had no evidence sinopulmonary or cutaneous disease. An epidural glucocorticoid injection was identified as potential route entry for this organism into central nervous system, reported state health department.

We report 3 cases of herpes simplex virus encephalitis in patients receiving tumor necrosis factor-alpha (TNF-alpha) inhibitors for rheumatologic disorders. Although TNF-alpha have been reported to increase the risk other infectious diseases, our knowledge, an association between anti-TNF-alpha drugs and has not previously described.

Background Lack of a gold standard for latent TB infection has precluded direct measurement test characteristics the tuberculin skin and interferon-γ release assays (QuantiFERON Gold In-Tube T-SPOT.TB). Objective We estimated sensitivity/specificity prevalence in prospective, US-based cohort 10 740 participants at high risk infection. Methods Bayesian class analysis was used to estimate among subgroups based on age, foreign birth outside USA HIV Results Latent varied from 4.0% foreign-born,...

HIV-1 infection leads to chronic inflammation and an increased risk of non-AIDS mortality. Our objective was determine whether AIDS-defining events (ADEs) were associated with overall cause-specific related mortality after antiretroviral therapy (ART) initiation.We included HIV treatment-naïve adults from the Antiretroviral Therapy Cohort Collaboration (ART-CC) who initiated ART 1996 2014. Causes death assigned using Coding Death in (CoDe) protocol. The adjusted hazard ratio (aHR) for among...

Abstract Introduction Extrapulmonary tuberculosis ( EPTB ) is difficult to confirm bacteriologically and requires specific diagnostic capacities. Diagnosis can be especially challenging in under‐resourced settings. We studied modalities clinical outcomes of compared pulmonary PTB among HIV ‐positive adults antiretroviral therapy ART programmes low‐ middle‐income countries LMIC ). Methods collected data from TB patients (≥16 years) 22 participating the International Epidemiology Databases...

Abstract Background Tuberculosis (TB) elimination within the United States will require scaling up TB preventive services. Many public health departments offer care for latent tuberculosis infection (LTBI), although gaps in LTBI cascade are not well quantified. An understanding of these be required to design targeted interventions. Methods We conducted a cohort study through Epidemiologic Studies Consortium (TBESC) 15 local department (LHD) clinics across States. Data were abstracted on...

Abstract Introduction Since its global reemergence in 2022, monkeypox (mpox) has demonstrated increased incidence and severity among people with human immunodeficiency virus (HIV [PWH]). Predictors of mpox diagnosis, vaccination, outcomes PWH are limited. Methods We included primary care visits after 1 January 2022 at 9 US sites participating the Centers for AIDS Research Network Integrated Clinic Systems Network. identified diagnosed between June 31 May 2023, through a combination...

Prompt diagnosis and treatment of fungal meningitis are critical, but culture is insensitive. (1,3)-β-d-Glucan (BDG) testing FDA approved for serological invasive disease; however, BDG not cerebrospinal fluid (CSF), the appropriate cutoff value unknown. We aimed to validate diagnostic accuracy CSF measurements among patients exposed contaminated methylprednisolone acetate (MPA).

Management of tuberculosis (TB) is challenging in HIV/TB-coinfected children. The World Health Organization recommends nucleic acid amplification tests for TB diagnosis, a 4-drug regimen including ethambutol during intensive phase (IP) treatment, and initiation antiretroviral therapy (ART) within 8 weeks diagnosis. We investigated treatment outcomes by diagnostic modality, IP regimen, ART status.We conducted retrospective cohort study among children enrolled at the International Epidemiology...

National US data on the burden and risks for hepatitis C virus (HCV) infection in people with human immunodeficiency (HIV) during direct-acting antiviral (DAA) era are limited. These important to understand current progress guide future efforts toward HCV microelimination.

Background People with HIV (PWH) have elevated cardiovascular risk. Underrepresented racial and ethnic groups in the southern United States are disproportionately affected, yet whether cardiology care for this at‐risk group improves blood pressure lipid control or prevents events is unknown. Methods Results We evaluated a cohort of PWH from underrepresented who received HIV‐related at 4 centers during 2015 to 2018 follow‐up through 2020. Primary outcomes were (<140/90 mm Hg) (low‐density...
