Introduction: Antimicrobial resistance (AMR) poses a significant threat, particularly in low- and middle-income countries (LMICs), exacerbated by inappropriate antibiotic use, access to quality antibiotics and weak antimicrobial stewardship (AMS). There is a need to review current evidence on antibiotic use, access, and AMR, in primary care across key countries.

Areas Covered: This narrative review analyzes publications from 2018 to 2024 regarding access, availability, and use of appropriate antibiotics.

Background: Despite the advancement of modern treatment approaches, several studies indicated a diminished health-related quality of life (HRQoL) in patients with gastrointestinal cancer. However, there is insufficient data about the HRQoL of gastrointestinal cancer patients in Kenya.

Aims: The study aimed to investigate HRQoL and its determinants in gastrointestinal cancer patients at Kenyatta National Hospital.

Introduction: Cancer therapy has remarkable potential for drug-related problems due to the high cytotoxicity and narrow therapeutic index of most anti-neoplastic regimens. However, there is a lack of comprehensive studies on drug-related problems in patients with gastrointestinal cancer in Kenya. Therefore, the present study aimed to investigate the prevalence, types and predictors of drug-related problems among gastrointestinal cancer patients at Kenyatta National Hospital.

Introduction: The overall 5-year survival rate for esophageal cancer patients in low- and middle-income countries was reported to be low, despite the availability of advanced treatments. Thus, this study aimed to assess determinants of survival outcomes among esophageal cancer patients in Kenya.

Methods: A retrospective cohort study was employed among 299 adult esophageal cancer patients.

There are serious concerns with rising antimicrobial resistance (AMR) across countries increasing morbidity, mortality and costs. These concerns have resulted in a plethora of initiatives globally and nationally including national action plans (NAPs) to reduce AMR. Africa is no exception, especially with the highest rates of AMR globally.

Background: Colorectal cancer is a growing burden in Africa. However, survival for patients with colorectal cancer remains low in sub-Saharan African countries, with the poorest survival, particularly at a late stage at diagnosis. Despite this, there is a paucity of sufficient data about the survival outcomes of colorectal cancer patients in Kenya.

Introduction: The incidence of gastrointestinal malignancies in Kenya is increasing, although there is a paucity of data on survival outcomes among gastric cancer patients. Hence, this study aimed to assess survival outcomes among adult gastric cancer patients at Kenyatta National Hospital.

Methods: A retrospective cohort study design was used to assess the survival outcomes among 247 gastric cancer patients.

Antimicrobial stewardship encourages appropriate antibiotic use, the specific activities of which will vary by institutional context. We investigated regional variation in antibiotic use by surveying three regional public hospitals in Kenya. Hospital-level data for antimicrobial stewardship activities, infection prevention and control, and laboratory diagnostic capacities were collected from hospital administrators, heads of infection prevention and control units, and laboratory directors, respectively.

Background: The COVID-19 pandemic has already claimed considerable lives. There are major concerns in Africa due to existing high prevalence rates for both infectious and non-infectious diseases and limited resources in terms of personnel, beds and equipment. Alongside this, concerns that lockdown and other measures will have on prevention and management of other infectious diseases and non-communicable diseases (NCDs).

Background: Chemotherapy-related side effects and their management in patients with Non-Hodgkin's Lymphoma (NHL) are not well defined in developing countries, including Kenya. This needs addressing considering the high number of patients with cancer in these countries. Consequently, we sought to determine the common side effects of chemotherapy used to treat NHL in pediatric patients and its implications.

Background: Chronic kidney disease (CKD) patients are prone to medication-related problems (MRPs). Few studies address the clinical relevance of MRPs among CKD patients in sub-Saharan Africa.

Objective: To investigate the frequency and predictors of MRPs among adult CKD patients treated at a tertiary care facility in an urban sub-Saharan setting.
