About Global Health Pharmacology and Therapeutics (GH-Pharma)

Research

Our research is focused on tropical pharmacology - investigating genetic and environmental factors influencing between individuals and population variations in treatment response, including efficacy and susceptibility to adverse events such as drug induced liver and CNS toxicity.

We are working on treatment optimization of several communicable and non-communicable diseases including the three most deadly infectious diseases (HIV/AIDS, tuberculosis, and malaria), neglected tropical diseases, breast cancer and antimicrobial resistance that claim millions of lives worldwide, especially in sub Saharan Africa, where the disease burden is paramount and yet little is known about the impact of host-genetic factors, drug interactions, coinfections and comorbidity, and nutrition on both the safety and efficacy of therapy.

We are conducting several case-control, parallel comparative, prospective observational studies, randomized clinical trials, drug interaction and dose optimization studies in various patient cohorts including adult, children and pregnant women. For the past 20 years, we have been conducting several pharmacogenetics, pharmacokinetics, and pharmacodynamics, drug-drug interaction studies in well-characterized large prospective patient cohorts in East Africa (Ethiopia, Kenya, Tanzania, Uganda and Rwanda).

Through the PROFORMA project (http://proforma.ki.se/), we are currently conducting pharmacovigilance and post marketing surveillance of mass drug administration and vaccinations in Ethiopia, Kenya, Tanzania and Rwanda.  Through the PREGART project (https://www.pregart.eu/) we are investigating the safety and efficacy of Dolutegravir and EFV400 for pregnant and breastfeeding women: a randomized non-inferiority clinical trial in Uganda and Ethiopia. Our goal is to provide evidence-based recommendations for personalized medicine, and for policymakers to improve/revise treatment guidelines and global health policies.

Research areas

  1. Treatment optimization of HIV/AIDS, tuberculosis and malaria - 'The big three”
  2. Maternal and child health
  3. Neglected tropical diseases (diverse group of infectious diseases that are endemic in tropical and subtropical regions, such as schistosomiasis, leishmaniosis, onchocerciasis)
  4. Discovery and validation of novel genetic, metabolic and proteomic biomarker for drug induced liver toxicity
  5. Non-communicable diseases (breast cancer, diabetes, cardiovascular diseases)
  6. Antimicrobial resistance, community and hospital acquired infections.
  7. Pharmacovigilance and post-marketing surveillance in public health program involving mass-drug-administration and immunization.
