Dr. Alexander Kwarteng’s research seeks to elucidate the immune response and molecular mechanisms underlying diseases of poverty including human filarial infections. By extension, he seeks to understand the complex host-parasite interaction and molecular underpinning behind the complications people suffering from filarial infections present with. Alex has key interest in understanding the role of colonizing bacterial in complicating lymphedema development. His research team develops and promotes the use of innovative strategies to alleviate the pain and psychological burden among people suffering from lymphedema (elephantiasis) and hydrocele such as promoting foot and personal hygiene. Alex is doing this using an interdisciplinary approach and a cultural perspective, to fight social stigmatization and depressive mental illness in LF endemic communities in Ghana. In recent years, his research interest has expanded to include: immunology education in developing countries, computational immunology, infectious diseases and non-communicable diseases such as cancer.
Title for project: The frequency of filarial attacks among lymphedema patients: A focus on leg stage, adherence to foot-care hygiene, and the impact of seasonal variations (LF-ATTACK)
Our understanding of the disease (lymphedema) dynamics and the impact of environmental factors on the progression of lymphedema is limited. Therefore, knowledge of the seasonal variations on filarial attacks among lymphedema patients will be key in the development of appropriate interventions for effective management of these attacks. We anticipate that this study will shed lights on the dynamics of LF attacks among lymphedema patients. Through this study, our understanding of the impact of environmental factors (weather) on lymphedema disease progression will be expanded thereby serving as the basis for the development of new management practices or revising existing ones where necessary.
Title for project: Microbial pathogens contributing to non-healing wounds among lymphatic filariasis patients in Ghana (LF-BAC)
Identifying the factors that promote non-healing wounds is crucial in developing novel therapeutics that will eventually make individuals with filarial diseases productive. This project seeks to characterize and compare the microbial populations from wounds of filariasis patients and non-filarial patient’s wounds; to determine the antimicrobial susceptibility of isolated microbial populations; to determine the differential host immune response among patients with advanced filarial wounds and non-filarial patient’s wounds in filarial endemic communities in Ghana.
