Filter by:In Mexico City, the main cause of mortality among people living with HIV (PLHIV) continues to be opportunistic infections (OIs). Early detection of OIs allows their timely treatment and improves their prognosis. The use of rapid diagnostic tests (RDT) based on antigens of the most frequent causative agents of OIs allows adequate screening of these patients and facilitates decision making at the point of care. Unfortunately, these studies are not widely available in the different PLHIV care centers in the CDMX. We will conduct an open-label, non-inferiority uncontrolled clinical trial to investigate the diagnostic performance of urinary lipoarabinomannan, urinary Histoplasma antigen and serum Cryptococcus antigen in patients presenting for care with advanced HIV in CDMX, supported by rapid cluster of differentiation 4 (CD4) testing with lateral flow technology. Four referral hospitals will participate over 12 months. All patients with diagnosed HIV disease and suspected advanced disease presenting for care at participating centers will be included in the study. An inventory of approximately 1000 RDT will be obtained and distributed among the participating sites. A study coordinator will be hired and will visit each site once a week to collect the study variables and follow up on the included patients. The primary outcome of the study will be the percentage of patients with advanced disease who present with diagnoses made by RDT compared to historical controls of patients diagnosed with OI in 2022 at participating centers by conventional methods. Secondary outcomes will be time to initiation of antiretroviral therapy (ART), time to initiation of OI treatment, and 30-day mortality after HIV diagnosis.
This study aims to investigate the possible safety and efficacy of probiotics (Bifidobacterium Infants, Enterococcus Feacium, and Lactobacillus Acidophilus) on the eradication rate of Helicobacter pylori and the incidence of adverse effects (AEs) of the concurrent rescue regimen in a patient with persistent H. Pylori infection.
The purpose of this study is to evaluate the effect of probiotics during vonoprazan-amoxicillin dual therapy on the gut microbiota in Helicobacter pylori eradication and to investigate whether the eradication rate of H.pylori will be improved when adding probiotics
The goal of this prospective interventional study is to evaluate the impact of antibiotic prophylaxis on bloodstream infections after liberation of extracorporeal membrane oxygenation therapy. The main questions aims to answer are: • does application of vancomycine prior to ECMO liberation have an impact of bloodstream infections? Participants will get 1 dose of vancomycine I.V. (15-20 mg per kgKG) prior to liberation of ECMO. Researchers will compare this interventional group to a group without antibiotic prophylaxis.
CLUE trial aims to determine the feasibility and predictive value for surgical site infection (SSI) of continuous glucose monitoring (CGM) in emergency laparotomy patients with diffuse peritonitis.
This is a randomized, open label, comparative Phase II trial being conducted to determine whether fecal microbiota transplant using Penn Microbiome Therapy (PMT) products helps standard therapy eradicate antibiotic-resistant bacteria.
Urinary tract infection is a common infectious disease in clinic. Although urinary tract infection can be initially diagnosed by clinical sign and symptom, signs and urine routine, the application of appropriate antibiotic therapy depends on the further identification of pathogens. Metagenomic sequencing has been widely used in clinical pathogen diagnosis, especially in difficult infectious diseases. ICompared with tissue samples, cerebrospinal fluid, bronchoalveolar lavage fluid, whole blood and other samples, the application of mNGS in urine samples is relatively limited because incorrect sampling methods before and after collection of urine samples are easy to contaminate the samples and the colonization of distal urethra, periurethral skin and vagina will interfere with the interpretation of reports. Previous small sample studies have shown that the sensitivity of mNGS in urinary tract infection is high, but the specificity is relatively low, and there are many problems such as difficult interpretation of reports and low clinical conformity. This is closely related to the mNGS technology algorithm, such as the inability to eliminate the influence of urinary system background bacteria, and the ambiguity of short sequence alignment, which makes it difficult to distinguish homologous pathogens. In this study, based on the standard mNGS sequencing process, the improved Z value analysis method was used to select strictly enrolled clinical samples and compare them with pathogen culture to observe the clinical value of mNGS with Z value analysis method in the treatment of urinary tract infection.
The researchers collect patients who accepted eradication program of the helicobacter pylori but failed to eradicate helicobacter pylor from the outpatient clinic. After rescue therapy, evaluating the effect of retreatment interval on eradication effect of Helicobacter pylori infection.

The goal of this observational study is to describe the immune signature of acute pulmonary infection.The main questions it aims to answer are: 1. Nasal mucosal immune response in patients with influenza infection 2. Difference of immune response between Viral sepsis and Bacterial sepsis 3. Immunological differences between Viral sepsis and Viral pneumonia
