Abstract

Due to the persisting development of SARS-CoV-2 variants, studies on the kinetics, duration, and function of antibodies are essential for vaccine development and long-term immunity prediction. This longitudinal study examined post-vaccination antibody responses in people after receiving CoronaVac or ChAdOx1 vaccines with or without a history of SARS-CoV-2 infection. Conducted in Indonesia between August 2021 and May 2023, this study involved 121 participants divided into two groups based on the received vaccine types and monitored for 18 months post-second dose vaccination by assessing the binding antibody (BAb) level and neutralizing antibody (NAb) inhibition rate at six time points. The study also documented the participants’ age, gender, and body mass index (BMI). Before the first dose vaccination, 85 (70.25%) participants were reactive BAb (defined by BAb level ≥50 AU/mL) indicating a history of infection. In the CoronaVac group, only 53.1% were reactive BAb. However, 100% of participants were positive NAb (defined by NAb inhibition rate ≥30%), which indicates a past history of infection with low initial or rapidly decreasing BAb levels. In the ChAdOx1 group, 81,9% of participants were reactive, while only 54.2% were positive NAb, suggesting a recent infection with a high BAb level but a relatively low NAb inhibition rate. During the 18 months post-second dose vaccination, the BAb levels fluctuated. However, 100% of participants were positive NAb. No significant difference in antibody response was documented among participants with or without infection history. Also, no significant impact was presented by the factors of sex, age, and BMI. The findings highlight the crucial of the vaccine in public health and how vaccination strategies could be optimized effectively during and after the post-pandemic.

Abstract

Liddle syndrome, a rare form of monogenic hypertension, poses significant diagnostic and therapeutic challenges due to its phenotypic variability and the need for genetic testing. The rarity of the condition, coupled with the limited availability of first-line treatments such as epithelial sodium channel (ENaC) blockers, makes this case report particularly urgent and novel, highlighting alternative management strategies in resource-limited settings. The aim of this case report was to present the diagnostic challenges, therapeutic strategies, and clinical outcomes of a patient with Liddle syndrome who did not have access to ENaC blockers, emphasizing the importance of early recognition and personalized treatment. A 35-year-old female presented with resistant hypertension (190/100 mmHg) and bilateral limb weakness. Laboratory results revealed persistent hypokalemia, hypernatremia, and metabolic alkalosis. Low aldosterone levels, alongside clinical and family history, led to the diagnosis of Liddle syndrome. Genetic testing was not conducted due to resource limitations, and ENaC blockers were unavailable. The patients were managed with a combination of alternative antihypertensive agents, potassium supplementation, and a low-sodium diet. Although this approach led to modest improvements in blood pressure and motor strength, persistent hypokalemia and hypernatremia underscored the suboptimal control of the syndrome's underlying pathophysiology in the absence of ENaC blockers. This case highlights the challenges faced in resource-limited settings and the need for innovative strategies to manage rare conditions like Liddle syndrome. Liddle syndrome's diagnostic and therapeutic challenges underscore the critical importance of early recognition and access to targeted therapies. In the absence of ENaC blockers, alternative treatment strategies can provide some benefit, but they often fall short of optimal management. This case emphasizes the need for enhanced clinical awareness, improved access to genetic testing, and the development of personalized treatment approaches to achieve better patient outcomes.
