Electrolyte imbalance in infectious disease patients at King Abdulaziz Hospital, Jeddah.

ABSTRACT

Objectives: Infectious diseases are the common cause of morbidity and mortality among humans. Electrolyte imbalance occurs frequently in patients with infectious diseases. This study aims to identify electrolyte imbalances in hospitalised patients with infectious diseases. Methods: Two hundred and eighty-three patients with age mean 36.48 ± 18.86 years, consisting of 127 (53.4%) males, 111 (46.6%) females, enrolled in a retrospective cohort study carried out at the King Abdulaziz University Hospital, Jeddah, KSA from September to December 2020. All hospitalised patients with infectious diseases were included. Demographic data, comorbidity, and diagnosis were collected from patients' sheets. Serum levels of electrolytes (chloride, potassium, sodium), urea, and creatinine were collected at admission (period 1), during hospital stay (period 2), and at discharge (period 3). Levels were compared during different periods. Results: Most infectious diseases were viral infections (63.4%), while comorbidity was diabetes mellitus (7.1%). Serum chloride elevated from period 1 to period 3 (P = 0.046). Sodium elevated between period 1 and both period 2 and period 3 (P < 0.001). Urea decreased between period 1 and both period 2 (P = 0.018) and period 3 (P < 0.001). Creatinine decreased between period 1 and both period 2 and period 3 (P < 0.001) and between period 2 and period 3 (P < 0.001). Patients with decreased chloride and sodium levels were mostly in the 1st period, while those with decreased potassium levels were mostly in the period 2. Conclusion: Prevalence of electrolyte imbalance in hospitalised patients with an infectious disease at the King Abdulaziz University Hospital, Jeddah was high, especially at admission and during the hospital stay.
