Utility of rapid chromatographic Immunoassay to rule out typhoid Fever among malaria negative patients.

Enteric fever, an endemic disease, is a significant health problem in developing low- and middle-income countries (LMICs). We studied the utility of Typhoid IgM/IgG assay in Widal titre positive samples among malaria negative patients. A total of 30 febrile patients were included. A blood sample was collected for performing the Widal test and a rapid lateral flow immune assay (Typhoid IgG/IgM tests). A total of 13/30 were positive on blood culture; however, Salmonella typhi grew on only two (6.6%). Of the 30 samples, 24 (80%) were positive for the rapid immunochromatographic (ICT) test None of the samples negative by the rapid ICT test grew Salmonella typhi. The rapid ICT test has better sensitivity and is easy to perform with minimal infrastructure; hence, it is a practical alternative to the age old Widal test.

Colistin Susceptibility Testing by Colistin Broth Disk Elution MIC Method among Carbapenem-resistant Gram-negative Blood Culture Clinical Isolates in a Tertiary Care Setting, East Delhi, India.

Background: Antibiotic resistance is a growing concern for bloodstream infections (BSIs), especially with the emergence of multidrug-resistant (MDR) gram-negative bacteria. In this study, we aimed to assess the pattern of colistin susceptibility using the colistin broth disc elution (CBDE) method among carbapenem-resistant gram-negative clinical isolates from blood cultures in a high burden tertiary healthcare setting in East Delhi. Methods: A total of 106 carbapenem-resistant gram-negative clinical isolates were tested. The most common isolates were Klebsiella pneumoniae, Escherichia coli, Enterobacter species, and Klebsiella oxytoca by CBDE method. Result: All the carbapenem resistant gram-negative bacterial blood culture isolates showed intermediate colistin susceptibility. This was statistically significant by chi-square test (p<0.5). Conclusion: This study highlights the need to monitor colistin resistance trends in the face of increasing antimicrobial resistance. Accurate surveillance of emerging colistin resistance is crucial for effective management of BSIs caused by carbapenem-resistant gram-negative bacteria.

Microbiological profile and their antibiogram of bloodstream infections amongst first and second surge of the COVID-19 patients in a tertiary care hospital.

Introduction: The world is experiencing a pandemic of coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2. The prescription of a superfluity of unnecessary antibiotics without regard for the potential for increased antimicrobial resistances is extensive and unimpeded during the COVID-19 pandemic. Aims: To compare the microorganisms and the pattern of antimicrobial resistance of bacteremia during the first and second waves of the COVID-19 pandemic in a tertiary care hospital. Methods and Material: This retrospective observational study, to compared the blood culture of the COVID-19 pandemic during the first wave (April 2020 to September 2020) and the second wave (April 2021 to September 2021). All the blood culture isolates were identified and the antimicrobial susceptibility testing was done according to standard guidelines. Results: Out of 1470 blood culture samples, 259 (17.6%) blood bacterial isolates were grown in the first wave and, out of 4200 blood culture samples, 711 (16.9%) bacterial isolated during the second wave of the COVID-19 pandemic. Coagulase-negative staphylococcus (CONS) was 32.8% followed by Staphylococcus aureus 29.7% in COVID first wave and staphylococcus aureus (48.9%) followed by Klebsiella pneumoniae (11.6%) during COVID second wave were the most prevalent isolates. Conclusions: This study shows that coagulase-negative staphylococcus aureus and multidrug-resistant Klebsiella spp. are the leading causes of bloodstream coagulase-negative infections during both the first and second wave in the bloodstream COVID-19 pandemic.

Bioavailable turmeric extract for knee osteoarthritis: a randomized, non-inferiority trial versus paracetamol.

BACKGROUND: To compare the efficacy and safety of bioavailable turmeric extract versus paracetamol in patients with knee osteoarthritis (OA). METHODS: In this randomized, non-inferiority, controlled clinical study, patients of knee OA were randomized to receive bioavailable turmeric extract (BCM-95®) 500 mg capsule two times daily or paracetamol 650 mg tablet three times daily for 6 weeks. The primary outcome measure was Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale. The secondary outcome measures were WOMAC total, WOMAC stiffness, and WOMAC physical function scores. Responder analysis of individual patients at different levels (≥ 20%, ≥ 50%, and ≥ 70%) for WOMAC score was calculated. TNF alpha and CRP levels were evaluated and adverse events (AE) were also recorded. RESULTS: Seventy-one and seventy-three knee OA patients, respectively in bioavailable turmeric extract and paracetamol groups, completed the study. Non-inferiority (equivalence) test showed that WOMAC scores were equivalent in both the groups (p value < 0.05) in all the domains within the equivalence limit defined by effect size (Cohen's d) of 0.5 whereas CRP and TNF-α were better reduced with turmeric extract than paracetamol. After 6 weeks of treatment, WOMAC total score, pain, stiffness, and function scores got a significant improvement of 23.59, 32.09, 28.5, and 20.25% respectively with turmeric extract. In the turmeric extract group, 18% of patients got more than 50% improvement and 3% of patients got more than 70% improvement in WOMAC pain and function/stiffness score and none of the patients in the paracetamol group met the criteria. CRP and TNF-α got significantly reduced (37.21 and 74.81% respectively) in the turmeric extract group. Adverse events reported were mild and comparatively less in the turmeric extract group (5.48%) than in the paracetamol group (12.68%). CONCLUSION: The results of the study suggest that bioavailable turmeric extract is as effective as paracetamol in reducing pain and other symptoms of knee osteoarthritis and found to be safe and more effective in reducing CRP and TNF-α.
