Malnutrition Inflammation Complex Syndrome in Pre-dialysis Chronic Kidney Disease Patients in a Nigerian Tertiary...

Malnutrition Inflammatory Complex Syndrome (MICS) is a non-traditional cardiovascular risk factor that is associated with poor overall outcomes in chronic kidney disease (CKD). However, it has not been well studied among Nigerian CKD population despite its potential for response to therapeutic intervention.

To determine the prevalence and severity of MICS and some of its associated factors among pre-dialysis CKD patients.

This was a cross-sectional study that involved 51 predialysis CKD patients and 51 healthy controls. MICS was assessed using malnutrition inflammation scores (MIS) among the participants. MIS of > 6 was used as the criterion for diagnosis of MICS.

The mean ages of the CKD and control groups were 50.96 ± 11.42 years and 48.31±9.83 years, respectively. The prevalence of MICS was significantly higher in the CKD group compared to the control group (54.90% vs 7.8%; P =<0.001). MICS was mild and moderate to severe in 64.3% and 35.7% of the predialysis CKD participants, respectively. Among all the study participants, lower educational level, low estimated glomerular filtration rate, (P<0.001), dyslipidemia (P =<0.001), anaemia (P=<0.001) and hypertension (P=0.033) were significantly associated with MICS. There was significant negative correlation between the MIS and estimated glomerular filtration (r = -0.73, P <0.001), and haematocrit (r = -0.335, p =0.016).

MICS was common in pre-dialysis CKD population. It was significantly associated with hypertension, dyslipidemia, educational level, anaemia and estimated glomerular filtration rate in pre-dialysis CKD patients. Early diagnosis and treatment may reduce poor cardiovascular outcomes in them.
