Immunohistochemistry Expression of Programmed Death-Ligand 1 in Colorectal Carcinoma among Nigerians.

Background: Colorectal carcinoma (CRC) is the most common gastrointestinal malignancy in Nigeria with a dismal 5-year survival rate. Interactions between the CD8+ T-lymphocytes and the immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-ligand 1 (PD-L1) expressions are important. Novel antibodies have been developed against these immune checkpoints and have been found to improve clinical outcome in many solid organ malignancies.

Relationship Between Hematologic Inflammatory Markers and Glycemic Control in Type 2 Diabetes Mellitus Patients in a Tertiary Hospital in Nigeria.

Introduction: Hematologic inflammatory biomarkers derived from a full blood count (FBC) are elevated in Type 2 diabetes mellitus (DM). In low- and middle-income countries like Nigeria, a FBC is an affordable and easily available test, even in rural areas.

The Need for Adult Pneumococcal Vaccination in Nigeria.

Despite universal immunization coverage on a global scale among children, the vast majority of immunocompromised adults, and particularly the elderly, remain unvaccinated. Considering that a significant proportion of mortality from pneumococcal disease occurs among the elderly, preventive measures through pneumococcal vaccination in adults, especially the elderly with co-morbidities, needs to be urgently explored and implemented in Africa, and particularly in Nigeria, to stem the tide of deaths resulting from pneumococcal disease among this population. This article looks at the pneumococcal epidemiology and burden of disease in Nigeria, as well as the vaccines available and the rationale for adult pneumococcal vaccination.
