Introduction: Human immunodeficiency virus (HIV) patients may undergo renal damage due to disease or nephrotoxic drugs. Tenofovir has been associated with the development of renal impairment. The aim of this study was to compare trends in creatinine clearance (CrCl) and estimated glomerular filtration rate (eGFR) in patients on highly active antiretroviral therapy (HAART) and to compare the same between patients on tenofovir- and nontenofovir-based regimens.

Methods: A prospective observational study was conducted. We followed 244 patients for 2 years. The demographic, clinical, and laboratory parameters of the patients were recorded at baseline, 1 year of therapy, and 2 years of therapy. The data were analyzed using dividing patients into tenofovir- and nontenofovir-based groups. Statistical analysis was performed using the Chi-square test, paired and unpaired t-tests, and Fisher's exact test.

Results: The mean blood urea nitrogen and serum creatinine in both groups were comparable at the start of the therapy. The decline in CrCl and eGFR in all patients on HAART for 2 years was statistically significant, irrespective of tenofovir usage. The mean decrease in eGFR in the tenofovir group was 12.4 mL/min/1.73 m² and in the nontenofovir group, 9 mL/min/1.73 m², though the differences between eGFR and CrCl were not significant between the two groups at any point.

Conclusion: Even though previous studies have suggested that HAART usage can slow the decline in kidney function in people living with HIV, patients who receive HAART still show a statistically significant decline in renal function parameters, akin to the observations of other such studies in low-resource settings.

Introduction: Acute encephalitis syndrome (AES) is one of the important causes of mortality among children in India. Active management of the cases, followed by addressing the cause of AES, is the key strategy for preventing mortality. Lack of laboratory facility and difficulty of sampling blood and cerebrospinal fluid (CSF) for assessing causes is one of the important barriers to early initiation of treatment. The main objective of the study is to validate the Scrub Typhus Encephalitis Assessment Tool (SEAT) for the management of AES.

Methods: The study is a continuation of a study conducted in a tertiary care hospital in Eastern Uttar Pradesh. A machine learning (LightGBM) model was built to predict the probability of scrub typhus diagnosis among patients with acute encephalitis. Three models were built: one with sociodemographic characters, the second with Model 1 variables and blood parameters, and the third with Model 2 variables and CSF parameters.

Results: The sensitivity of diagnosing the scrub typhus case was 71%, 77.5%, and 83% in Model 1, Model 2, and Model 3, respectively, and specificity was 61.5%, 75.5%, and 76.3%, respectively, in the models. In Model 1 fever duration, in Models 2 and 3, neutrophil/lymphocyte ratio was the most important predictor for differentiating the scrub and nonscrub cases.

Conclusion: With the available sensitivity and specificity of the tool, the SEAT can be a valuable tool for the prediction of scrub typhus as a cause of AES cases in remote areas.

Melioidosis, caused by Burkholderia pseudomallei, is a challenging infectious disease with global implications, primarily affecting Southeast Asia. We present the case of a 24-year-old male with a curious history of tobacco use, presenting with fevers, weight loss, and genitourinary symptoms. Diagnostic challenges arose as symptoms mimicked other diseases. Disseminated melioidosis was confirmed via Gram staining and positron emission tomography scan findings, emphasizing the disease's diverse clinical manifestations. Treatment with ceftazidime and cotrimoxazole led to prompt recovery. Notably, the patient's tobacco use linked to contaminated water highlights a unique transmission route. This case underscores the need for heightened awareness and preventive measures in endemic regions.

Introduction: People living with human immunodeficiency virus (PLHIV) are known to have an increased prevalence of traditional cardiovascular risk factors and are at a higher risk of cardiovascular disease (CVD). This study was done to assess the CVD risk factors in treatment naïve PLHIV in a center of the national program.

Methods: In this cross-sectional explorative study, traditional CVD risk factors were assessed, and 10-year Framingham and atherosclerotic cardiovascular disease (ASCVD) risk score were calculated in treatment naïve PLHIV attending the antiretroviral therapy (ART) center, IMS, BHU.

Results: The study included 337 ART naïve patients. The prevalence of CVD risk factors in treatment naïve PLHIV - were low high-density lipoprotein cholesterol levels (81.4%), high triglyceride levels (32.7%), smoking (32.3%), obesity (13.6%), hypertension (5%), diabetes (2.7%), and high low-density lipoprotein cholesterol levels (2.1%). Moderate-to-high 10-year Framingham Risk Score and American Heart Association/American College of Cardiology 10-year ASCVD risk score were 10.8% and 8.9%, respectively. In Framingham Risk Score, age ≥40 years (odds ratio [OR] - 131) (95% confidence interval [CI] - 6.5-1043) alcohol intake (OR - 5.14 [95% CI - 1.82-14.46] and presence of tuberculosis (OR - 4.78) (95% CI - 1.48-15.40), while in ASCVD risk score history of alcohol intake (OR - 26.20 [95% CI - 3.1-216.8] were at higher risk of CVD in multivariate variate analysis.

Conclusion: CVD risk factors were common among ART naïve patient. Thus, screening, education, and treatment of CVD risk factors should be done in these patients at initiation of care.

Introduction: Catheter-related persistent Candida infections (CRPCI) may develop after Candida catheter-related bloodstream infections (CRBSI) due to colonization of the newly inserted catheter. However, the optimal timing for new catheter insertion remains controversial. The aim of this study was to determine the clinical features of CRBSI due to Candida species and CRPCI. This was a retrospective study conducted in a teaching hospital in Japan.

Methods: We retrospectively collected clinical information on hospitalized patients diagnosed with Candida CRBSIs by catheter tip culture from 2015 to 2020. CRPCI was defined as the growth of the same Candida species from the tip culture of a newly inserted catheter after the onset of a Candida CRBSI. The Chi-squared and Fisher's exact tests were used to compare differences between the case and control groups.

Results: Sixty-three cases of Candida CRBSI were collected. Fifty-four (85.7%) received total parenteral nutrition. CRPCI developed in 12 (48%) patients of the 25 in whom cultures of newly inserted catheters were performed. Despite antifungal therapy in these patients, persistent fungemia incidence was significantly higher (50.0% vs. 9.1%, odds ratio = 10.0, P = 0.033). The mean number of days from removal of infected catheter to reinsertion was significantly shorter for patients with CRPCI (0.27 days vs. 3.08 days, P = 0.038).

Conclusions: Total parenteral nutrition may be a major risk factor in the development of Candida CRBSI. CRPCI often leads to persistent fungemia. Early insertion of a new catheter after removal of an infected catheter may be a risk factor for CRPCI.

Aspergillus is a ubiquitous saprophytic mold that humans and animals constantly inhale. In health, the conidia are eliminated by the innate immune system. However, a subset of individuals with risk factors such as neutropenia, receiving high doses of glucocorticoids or certain biologicals, and recipients of hematopoietic or solid-organ transplants develop invasive aspergillosis. The mortality associated with invasive aspergillosis is 42%-64%. The early diagnosis of invasive pulmonary aspergillosis in patients without classical risk factors remains challenging. We present a case of an elderly female with uncontrolled diabetes mellitus who presented with acute-onset chest pain, breathlessness, and cough without expectoration. On evaluation, her chest radiograph showed a mass lesion in the right upper zone. ¹⁸Fluorodeoxyglucose (FDG)-positron emission tomography-computed tomography showed two FDG-avid lesions in the apical and medial segment of the right upper lobe. The lung biopsy was negative for malignancy; however, she was diagnosed with invasive pulmonary aspergillosis based on serum and bronchoalveolar fluid galactomannan positivity. She was managed with voriconazole with complete resolution of the lesion.

Introduction: Hydatidosis/cystic echinococcosis (CE) is considered a neglected disease due to its preventive nature and impact on low-income populations. In Latin America, there is a high incidence, and in the high Andean regions, it is considered an endemic disease. The objective of this study was to quantify and analyze the scientific production of hydatidosis/echinococcosis through a bibliometric analysis in Latin America up to 2022.

Methods: A bibliometric analysis study was conducted based on the scientific production of CE in the SCOPUS database until 2022 in Latin American countries. Information was collected through a systematic search. Frequencies and percentages were used to summarize the variables captured in the final database.

Results: Scientific production showed growth over the years, with Argentina, Uruguay, and Chile having the highest production. In addition, there has been a trending use of the term "neglected disease" since 2018. The most cited articles were primarily narrative reviews, book chapters, and original articles in that order. Only 27% of the studies were funded by an institution in Latin America.

Conclusion: Scientific production in Latin America regarding CE is on the rise, especially in countries with high incidence rates. Furthermore, these countries demonstrate a significant network of international collaboration.

Introduction: The COVID-19 infection is an ongoing public health crisis causing millions of deaths worldwide. COVID-19 patients admitted to the intensive care unit (ICU) are more vulnerable to acquire secondary bloodstream infections (sBSIs) which cause a significant morbidity and mortality. Thus, we aim to assess the risk factors of sBSIs and outcomes in COVID-19 ICU patients.

Methods: One hundred blood culture samples with growth (cases) and other 100 blood culture with no growth(controls) were collected.. All the demographic data, laboratory data and antimicrobial resistance pattern were analysed . Blood culture bottle received in the Microbiology laboratory were loaded into Automated blood culture system. Flagged bottles were processed for final identification by MALDI TOF and automated antibiotic susceptibility testing. Flagged bottles were processed for final identification by MALDI TOF and automated antibiotic susceptibility testing.

Results: Raised C-reactive protein (CRP) (P = 0.0035), interleukin-6 (P = 0.0404), mechanical ventilation (MV) (P = 0.024), prior antimicrobial exposure (P = 0.002), longer ICU stay with median 11 days (P = 0.022), and higher mortality rate (P = 0.001) were significantly associated with the BSI. A significant proportion of BSIs were Gram-negative bacteria (n = 115) such as Acinetobacter baumannii 38 (33%) and Klebsiella pneumoniae 30 (26%). Monomicrobial organisms in blood yielded a higher proportion in our study 72 (72%). The highest resistance for Acinetobacter species (50) was observed with ceftazidime 29 (96.6%) amikacin 48 (96%), meropenem 48 (96%), cefotaxime 47 (94%), ciprofloxacin 46 (92%), and netilmicin 46 (92%). K. pneumoniae was highly resistant to cefotaxime 29 (96.6%), ceftazidime 29 (96.6%), ciprofloxacin 22 (73.3%), and cefuroxime 21 (70%). Among Gram-positive organisms, Enterococcus species showed that a resistance for high-level gentamicin and penicillin was 66.6%.

Conclusions: Raised CRP, need of MV, prior antimicrobial exposure, and longer ICU stay should alarm clinicians for BSI. Hence, our study highlights the associated risk factors for BSI and emphasizes adherence to hospital infection control policies and antibiotic stewardship program.

Tuberculous paradoxical reaction presents as clinical deterioration during appropriate tuberculosis therapy and is a separate entity from treatment failure and drug resistance. We describe a case of central nervous system paradoxical reaction following tuberculous meningoencephalitis treatment in an immunocompromised patient with systemic lupus erythematosus.
