Once-Weekly Liposomal Amphotericin B Use for Maintenance and Consolidation Phase Treatment of Cryptococcal Meningitis in Patients With AIDS

Cryptococcal meningitis should be considered in individuals diagnosed with human immunodeficiency virus (HIV) infection and presenting with a cluster of differentiation 4 (CD4)-helper T cell count below 100 cells/ml. The 2022 guidelines from the World Health Organization (WHO) advocate for initiating treatment with a high dose (10 mg/kg) of liposomal amphotericin B, followed by flucytosine and fluconazole for a two-week duration. Additionally, alternative treatment options involving a combination of flucytosine and fluconazole are recommended. Consolidation therapy, as per the WHO guidelines, involves an eight-week course of fluconazole (800 mg), initiated after the induction phase. The dosage is then reduced to 200 mg/day, maintaining this level until the CD4 count exceeds 200 cells/mm3. Notably, the 2022 WHO guidelines prioritize a single dose of liposomal amphotericin B (LampB) over amphotericin B deoxycholate (AmpB-D) at 1 mg/kg due to its association with fewer side effects, including decreased mortality, kidney damage, and anemia. These recommendations are founded on the outcomes of the Ambisome Therapy Induction Optimization (AMBITION-CM), a multicenter, open-label, randomized controlled trial. This case report details the outpatient management of cryptococcal meningitis in a 47-year-old male with acquired immunodeficiency syndrome (AIDS) who exhibited intolerance to fluconazole. In this scenario, the decision to employ liposomal amphotericin B (LampB) as the sole agent for treatment during the outpatient phase was driven by challenges in tolerating fluconazole. Despite the absence of specific research on LampB's standalone use during the maintenance and consolidation phases, concerns regarding the patient's adverse reaction to fluconazole influenced the choice. Notably, LampB's once-weekly infusion schedule, although more expensive than AmpB-D, contributes to enhanced patient compliance. Exploring alternatives to traditional medications, such as interferon-gamma (INF-γ), Mycograb, 18B7, APX001, and T2307, holds promise in targeting novel antigens or complementing existing treatment regimens. Post-discharge, the patient received weekly LampB infusions alongside antiretroviral therapy (ART), resulting in an undetectable viral load and an increased CD4 count. A subsequent cerebrospinal fluid analysis post-discharge revealed a positive India ink stain but negative cultures for Cryptococcus, underscoring the necessity for a comprehensive and adaptable approach in managing cryptococcal meningitis.

Salmonella Group B Ileitis Mimicking Crohn's Disease: A Case Report

Salmonellae, considered among the enteric-fever-causing pathogens, is associated with a range of human infections, including gastroenteritis, bacteremia, and osteomyelitis. Salmonella-induced mesenteric adenitis and terminal ileitis resembling acute appendicitis have been reported in the literature. Here, we present a rare case of a patient presenting with severe acute active ileitis and colitis mimicking Crohn's disease with no prior history of inflammatory bowel disease and found to have Salmonella group B bacteremia.

A Rare Case of Acute Myeloid Leukemia Initially Presenting With Fever of Unknown Origin and Rapidly Progressing Pericardial Effusion

This case report highlights a patient who had persistent fevers for weeks and rapidly progressing pericardial effusion following a positive test for coronavirus disease 2019 (COVID-19) two weeks before presentation to the hospital. The initial thought was that her fever was of infectious etiology, but relevant investigations led to the diagnosis of acute myeloid leukemia (AML). AML, which is characterized by clonal expansion of immature "blast cells" in the peripheral blood and bone marrow resulting in ineffective erythropoiesis and bone marrow failure, is the most prevalent form of leukemia. It is the most aggressive form of leukemia, which has varying prognoses determined by the subtypes. This report explores the association between AML, fever of unknown origin, and pericardial effusion, shedding light on a notable clinical aspect. Fever in AML may be attributed to underlying inflammatory processes, cytokine dysregulation, or bone marrow failure. Recognition of fever as a potential indicator of AML contributes to enhanced clinical vigilance. Pericardial effusions and cardiac tamponade, although rare, can be a presenting feature of AML, and can present side by side with fever of unknown origin as seen in this case report.

A Rare Case of Polymerase Chain Reaction-Negative Severe Clostridioides difficile Infection

Accurately diagnosing Clostridioides difficile infection (CDI) is crucial for effective patient management. A misdiagnosis poses risks to patients, leads to treatment delays, and contributes to infection transmission in healthcare settings. While using polymerase chain reaction (PCR) to amplify the toxin B gene is a sensitive method for detecting toxigenic C. difficile, there is still a risk of false-negative results. These inaccuracies could have significant consequences for diagnosing and treating CDI, emphasizing the need for careful consideration and other diagnostic approaches. This case report highlights a patient with severe CDI who had negative PCR and toxin and a biopsy showing pseudomembranous colitis on further testing due to persistence and worsening of symptoms. In the diagnosis of C. difficile infection, healthcare providers should consider clinical symptoms, although diarrhea, which is a major sign of CDI, can be due to other causes. Even in the presence of negative PCR results, if a patient displays symptoms consistent with C. difficile-associated disease, healthcare providers may still contemplate treatment.

When Influenza, Bacterial Pneumonia, and COVID-19 Co-exist

In the United States, influenza virus and bacterial pneumonia are known to be the leading causes of hospitalization in the winter season. Although healthcare workers are knowledgeable about the management of these co-infections, with the coronavirus disease 2019 (COVID-19) global pandemic that occurred in 2019, a significant change has occurred. The symptoms and clinical manifestations of COVID-19 are similar to that of influenza virus and bacterial pneumonia which can present a unique challenge for healthcare workers. Many reports are available for influenza virus and bacterial pneumonia but none about influenza, bacterial pneumonia, and COVID-19 co-infection. Here, we present the case of a patient who was admitted with COVID-19, influenza, and bacterial pneumonia co-infection, along with his clinical characteristics, laboratory findings, treatment plan, and outcomes.

The Roles of Fibrosis Index Based on Four Factors and Aspartate Transaminase-to-Platelet Ratio Index Scoring Systems as an Alternative to Transient Elastography Liver Stiffness in Liver Fibrosis Staging in Human Immunodeficiency Virus and Hepatitis C Virus Co-Infected Patients

Background

Liver biopsy used to be the gold standard to assess liver fibrosis in patients infected with hepatitis C virus (HCV). Nonetheless, due to its invasive nature, techniques such as transient elastography liver stiffness (TE-LS), fibrosis index based on four factors (FIB-4) and aspartate transaminase-to-platelet ratio index (APRI) scores are currently being used. FIB-4 and APRI scores have the advantage of low cost and are readily available, compared with TE-LS. Herein, we evaluated the diagnostic performance of these scoring systems as compared to TE-LS in assessing liver fibrosis in patients with human immunodeficiency virus (HIV) and HCV co-infection.

Methods

The medical records of patients with HIV and HCV co-infection who had TE-LS done at our facility between August 1, 2013 and January 1, 2020 were extracted and analyzed. Exclusion criteria include: 1) patients co-infected with hepatitis B virus; 2) invalid TE-LS assessment; 3) have ≥ 10th upper limit of normal (ULN) alanine aminotransferase (ALT) levels; and 4) excessive alcohol use. Patient demographics, medical history, biochemical and clinical data were retrieved. For each patient, we calculated the FIB-4 and APRI score. Descriptive analysis was performed and correlation of FIB-4 and APRI with TE-LS was assessed with GraphPad Prism statistical software.

Results

Five hundred forty-seven patients underwent TE-LS during the study period. After excluding those without complete laboratory parameters, the total study population was 344. Their age was 56 ± 10.4 years and 234 (68%) were male. The average aspartate aminotransferase (AST) and ALT were 27.95 and 30.73. The average platelet count was 224 and the average TE-LS was 7.29. Fourteen patients (4.1%) had TE-LS values between 9 and 11.9 kPa and were classified as F3, while 29 (8.5%) had TE-LS ≥ 12 kPa and were classified as F4. With the correlation analysis, both APRI (correlation coefficient, r = 0.1097, 95% confidence interval (CI) 0.0403 - 0.2130; P = 0.042) and FIB-4 (r = 0.0424, 95% CI -0.0634 - 0.1474; P = 0.4335) were not correlated with TE-LS stages of fibrosis.

Conclusion

In our cohort, we failed to demonstrate that APRI and FIB-4 are reliable alternatives for screening liver fibrosis in patients with HIV and HCV co-infection. Nonetheless, APRI score still has a potential role as a screening tool instead of TE-LS measurement, which is costly and not readily available. It will be important to corroborate these findings in another large cohort, since this may have an important impact on patient management.

Prevalence of coronary risk factors in healthy adult Kuwaitis

Obesity has been shown to be a serious health risk and is associated with a wide range of comorbid conditions, including diabetes mellitus, coronary heart disease (CHD), gall bladder disease, hypertension, osteoarthritis, and certain cancers. Studies in Kuwait and other Gulf States indicate that obesity is prevalent and may be increasing. Previous studies in Kuwait have mostly focused on the epidemiology of overweight and obesity in children, adolescents, and young adults. Relatively less is known about the prevalence of overweight and obesity and its correlates in older adults for whom obesity may be more closely related to CHD risk. The purpose of this study was to examine the prevalence of overweight and obesity in 9755 adult men and women and to determine the relationship of weight to other risk factors for chronic disease. For the first time we examine a sample of older Kuwaitis to explore the relationship between high BMI, hypercholesterolemia and hyperglycemia. One-third of adult Kuwaitis are obese (BMI > 30 kg/m2), 4.7% of Kuwaiti females have severe obesity (BMI > 40 kg/m2). BMI, cholesterol, and glucose values increase with age across the life span. Older Kuwaitis have a greater constellation of risk factors for chronic diseases. The results of a multiple linear regression model in which cholesterol values were studied, controlling for age, BMI, blood glucose, and sex revealed that age, BMI and sex were significant predictors of cholesterol values. These results indicate that actions to reduce obesity, hypercholesterolemia, and hyperglycemia are needed.
