Rethinking Diabetes Diagnosis in Sub-Saharan Africa: A New Understanding of Type 1 Diabetes
New research suggests that many young individuals diagnosed with Type 1 Diabetes (T1D) in Sub-Saharan Africa may actually have a different form of the disease, one not triggered by an autoimmune response, which is the hallmark of typical T1D. These findings could significantly alter how diabetes is identified, managed, and controlled across the region, leading to more tailored and effective patient care.The study involved 894 young people diagnosed with diabetes from Cameroon,Uganda,and South Africa. Researchers analyzed the data from this cohort and compared it with similar studies conducted in the United States involving the same age group.
“This presents a unique opportunity to understand the variations of T1D across different countries and ethnicities, notably those living in diverse environmental settings,” stated Dabelea, who also directs the Center for Fat and Diabetes Epidemiology throughout life (LED) at CU Anschutz.
A key discovery was that a ample number of adolescents in Sub-Saharan africa diagnosed with T1D lacked a common blood marker, known as Islet autoantibodies. These antibodies are typically present in individuals with T1D elsewhere in the world. Specifically, 65% of the T1D participants in this African region did not exhibit Islet autoantibodies.
Islet autoantibodies are crucial for differentiating T1D from othre diabetes types, such as Type 2 diabetes or monogenic diabetes, which have distinct causes and treatment approaches.
“This strongly indicates that many young people in this region are experiencing a distinct form of T1D that is not driven by autoimmune factors,” Dabelea explained.
When comparing these findings with US-based studies, researchers observed that a smaller, yet significant, proportion (15%) of Black participants diagnosed with T1D in the US exhibited a diabetes profile similar to those identified in Sub-Saharan Africa. These individuals also tested negative for autoantibodies and had low T1D genetic risk scores. in contrast, White individuals in the US with T1D displayed the typical autoimmune pattern, with genetic factors indicating autoimmune diabetes even in cases where autoantibodies were not detected.
“The identification of this T1D subtype within the Sub-Saharan African population and among individuals of African descent in the US suggests potential ancestral or genetic connections,” Dabelea commented. “This discovery underscores the importance of considering choice causes in this demographic and highlights the need for a deeper understanding of the underlying mechanisms.Such insights could be invaluable for developing future prevention and care strategies.”
