Acute renal failure (ARF) in developing countries: which factors actually influence survival

Area of Science:

• Nephrology
• Critical Care Medicine
• Public Health

Background:

• Acute renal failure (ARF) presents a global challenge with high mortality rates, particularly in resource-limited settings like sub-Saharan Africa.
• Limited access to renal replacement therapy (RRT) in sub-Saharan Africa necessitates careful resource utilization.

Purpose of the Study:

• To investigate factors influencing survival in patients with ARF.
• To evaluate the effectiveness of available RRT modalities, specifically acute hemodialysis (HD) and acute peritoneal dialysis (PD).

Main Methods:

• A study involving 46 patients with ARF, analyzing demographic data, causes of ARF, complications, and treatment modalities.
• Comparison of survival rates and influencing factors between patients treated with HD and PD.

Main Results:

• The overall survival rate for ARF was 56.5%.
• Factors significantly impacting survival included the availability of RRT, ARF etiology, gender, age, duration of oliguria, and pulmonary edema.
• No significant difference in survival was observed between HD and PD groups, though the number of HD sessions and duration of PD influenced outcomes.

Conclusions:

• ARF is associated with a high mortality rate, underscoring the need for accessible and timely RRT.
• Aggressive management of complications and prompt initiation of RRT are vital for reducing ARF mortality.
