Filter by:Cryptococcal meningitis (CM) is a fungal infection that causes a severe syndrome of meningitis that is 100% fatal without antifungal therapy. Even with antifungal therapy, mortality rates remain high, especially in Africa where the ongoing HIV/AIDS pandemic leads to higher prevalence of cryptococcosis. Combination of amphotericin and flucytosine (5-FC) is the mainstay of therapy for the initial management of CM. Indeed, it has even been shown that effective delivery of these therapies in Africa can lower mortality rates by 90%. This is a prospective open-label trial to compare the efficacy and safety of lower doses of 5FC during induction therapy to historical controls with standard 5FC dosing. Participants in the trial will receive 60mg/kg/day of 5-FC in 3 divided doses for 10 days. Single-dose liposomal amphotericin (10mg/kg) is preferred, if available. Amphotericin B 0.7-1.0 mg/kg/day may be used if needed. Historical controls drawn from the AMBITION trial will be used as a comparison group, selected weighted by inclusion/exclusion criteria, baseline characteristics and therapies received. Induction therapy for control group participants followed the 2018 WHO cryptococcal guidelines with 7 days of 5-FC 100mg/kg/day and 7 days of IV Amphotericin deoxycholate followed by 1200mg fluconazole/day for 7 days. The intervention group received single- dose liposomal amphotericin plus 5-FC and fluconazole 1200 mg/day. All participants will receive fluconazole 1200mg/day during consolidation therapy from day 1 to 14 then 800mg/day from day 15 to 10 weeks, and 200mg/day after 10 weeks. All participants will receive lumbar punctures at diagnosis, day 3, day 5-7, day 10-14, and additionally as required for control of intracranial pressure and documentation of CSF sterilization. Controls from Ambition will be matched for the same LP windows. Therapeutic LPs conducted during the first week have a ~70% relative survival benefit.
Patients with acute severe brain injury are usually admitted to the Intensive Care Unit. A substantial proportion of these patients will have disorders of consciousness (DOC) after interruption of sedation. It is difficult to reliably predict neurological outcome in these patients. Dependent on the extent of permanently damaged brain areas, DOC in patients with acute severe brain injury may improve or persist, eventually evolving into a minimal conscious state (MCS) or unresponsive wakefulness syndrome (UWS). These conditions are accompanied by long term severe disability. In current practice, the decision to withdraw life-sustaining support is made by interpreting the results of repeated bedside neurological examination and conventional CT-brain imaging. Reliable identification of patients with a possible good outcome, in whom treatment should not be withdrawn, is difficult. In this prospective observational cohort study we aim to identify patients with a good neurological outcome.
Extrapulmonary TB (EPTB) accounts for nearly 30% of TB cases in HIV endemic settings, such as South Africa. The diagnosis of extrapulmonary TB is complicated by the poor performance of Gene Xpert and TB Culture in extrapulmonary fluid (30-50% sensitive), as well as the poor specificity of ADA. We can therefore not reliably use these tests to diagnose EPTB as effectively as we use them in sputum samples. The current best practice for diagnosing pleural TB is to perform a pleural biopsy, which is both invasive and costly. A rapid, easy to use test is needed to allow accurate and fast diagnosis of EPTB. Interferon-gamma is released at high concentrations in extrapulmonary fluid in active EPTB. Antrum Biotech has developed the IRISA-TB assay (validated and SAHPRA licenced) for the diagnosis of EPTB. The study will assess the real-world performance of IRISA-TB compared to ADA, Gene Xpert, and TB Culture when used to diagnose EPTB. We will evaluate IRISA-TB's performance in the following patient groups: - Suspected TB pleural effusion (n= 650) - Suspected TB pericardial effusion (n= 280) - Suspected TB peritonitis (n= 200) - Suspected TB meningitis (n = 1040) As part of our evaluation, we will ask clinicians who treat these patients to provide their feedback on IRISA-TB. We will ask them to indicate to what extent the IRISA-TB test helped them to make treatment decisions. Finally, we will conduct an economic assessment to determine the true cost of diagnosing and treating EPTB to the health system and patients, and we will determine how IRISA-TB could potentially result in cost savings.
This is a multicenter, randomized, double-blinded, positive controlled study to evaluate the lot-to-lot consistency, immunogenicity and safety of Group ACYW135 Meningococcal Conjugate Vaccine (CRM197) in adults aged 18 to 55 years. Subjects will be randomized to receive investigational Lot 1, Lot 2, Lot 3 vaccine or control vaccine in a 1:1:1:1 ratio, with the subjects in experimental group randomly and equally assigned to three different batches of MCV4 for single-dose vaccination.
ACYW135 group meningococcal polysaccharide conjugate vaccine produced by Conchino Biologicals JSC is a covalent coupling conjugate of purified meningococcal podococcal polysaccharide of groups A, C, Y and W135 with CRM197 protein of diphtheria bacillus non-virulent mutant. The purpose of this clinical study is to evaluate the immunogenicity and immunopersistence of the ACYW135 meningococcal polysaccharide conjugate vaccine (CRM197 vector).
The goal of this clinical trial is to compare different approaches of spinal anesthesia in pregnant females who are having cesarean section. The main aim is • Which approach is better in terms of avoiding intraoperative and post operative complications Participants will be given anesthesia by 1. Midline approach 2. paramedian approach 3.

Randomized phase II clinical trial which aims to assess the impact on 3-month mortality and safety of adding adalimumab to standard treatment (anti-tuberculosis drugs and corticosteroids) in HIV patients with tuberculosis meningitis in 3 countries (Brazil, Mozambique, and Zambia).
This study will investigate the burden, causes, diagnostics, treatments and preventive measures related to meningitis in northern Uganda. We hypothesize that understanding the burden of meningitis, risk factors, diagnostics, treatments and the preventive measures will provide information regarding the gaps in care that can be addressed in order to improve the continuum of meningitis care. we hypothesize that our data will support the advocacy for the implementation of routine vaccination for the prevention of bacterial meningitis and improving guidelines for Cryptococcal antigen (CrAg) screening for prevention of cryptococcal meningitis, which will save lives in Uganda. Aim 1: To prospectively collect data on all patients with meningitis and meningitis symptoms who were admitted to Lira Regional Referral Hospital (LRRH) to assess burden, etiologies, pathogenesis, and outcomes of meningitis using modern diagnostic testing not previously available in Uganda. Aim 2: To perform CrAg screening of 10,000 HIV-positive patients to determine the prevalence of cryptococcal antigenemia (infection) and conduct a case control study to compare risk factors and outcomes among CrAg-positive patients and matched CrAg-negative controls based on age, sex, TB status, ART experience, CD4 count, and viral load.
After acquired brain injury (ABI), persons can experience emotional and behavioral difficulties, that can be painful both for the person and his/her family. This clinical study aims at measuring the effectiveness of a third wave cognitive behavioral therapy called "dialectical behavior therapy" (DBT). DBT aims at teaching persons emotion regulation skills, interpersonal effectiveness skills, mindfulness and distress tolerance skills through group and individual sessions. The study's hypothesis is that DBT, in an adapted format for persons with ABI can lead to - a better quality of life, emotional and behavioral regulation, and self-esteem - decrease in problematic behaviors - progress in life goals - increase post traumatic growth and spirituality - better family functioning and lesser burden for care givers - experiencing more emotions and more free will 45 persons with an ABI sustained more than 18 month back, will follow a 3 phases, follow-up with care as usual for 5 months, followed by 5 months of DBT, followed by 5 months of care as usual + DBT monthly sessions. Self- and family-questionnaire will explore quality of life, emotional regulation, self-esteem, stress, anxiety, cognitive difficulties, family functioning and coping, post traumatic growth and spirituality and will be compared across the 3 phases. Results will be analyzed at a group level but also at an individual level (each patient separately) to test for decrease in unwanted behaviors and at a dyadic level (the person and his/her spouse) to test for the mutual effect of regulating emotions. Persons' memories will by analyzed at 3 time points by a linguistic analysis, and experience of free will after ABI will be analyzed by transcribed narratives of participants.
