Introduction: Though the role of inflammation is reputedly associated with contrast induced nephropathy (CIN), especially in the setting of Acute Coronary Syndrome (ACS), current risk scoring systems do not address inflammatory factors. Neutrophil lymphocyte ratio (NLR), a proportion of two inflammatory markers, is reflective of the balance between innate and adaptive immune responses, and therefore has a strong predictive value. Methods: A cross-sectional analytical study done among adult Filipinos diagnosed with ACS who underwent Percutaneous Coronary Intervention (PCI) from January to December 2018 at Makati Medical Center. Exposure of interest includes baseline NLR count and pre-procedural serum creatinine. Outcome was the incidence of CIN based on serum creatinine 24-48 hours post-procedure. Results and Analysis: A total of 166 ACS patients were analyzed, of which 11 (6.62%) has CIN. Patients with pre-procedural NLR > 4.71 were approximately five times as likely to develop CIN (aOR 1.51 to 17.55, p = 0.009), with sensitivity 63.64%, specificity 80.65%, accuracy 79.52%, Youden’s index 44.29%. On multivariate analysis, NLR and STEMI were associated with increased odds for CIN. STEMI patients had approximately four times the odds of developing CIN (aOR 3.893, 95% CI 1.07 to 14.13, p = 0.039). Conclusion NLR > 4.71 in Filipinos with ACS who underwent PCI is associated with increased risk to develop CIN.

Objective: This study aims to determine the association of serum magnesium with distal symmetric peripheral neuropathy among persons with type 2 diabetes mellitus (DM). Methodology: A cross-sectional analytical study among adult Filipinos with Type 2 DM. Logistic regression was used to determine the association of serum magnesium with DSPN diagnosed by the Michigan Neuropathy Screening Instrument. The null hypothesis was rejected at 0.05α-level of significance. Results: The average serum magnesium levels were similar between those with versus without DSPN (2.06 ± 0.32 vs 2.05 ± 0.23, p = 0.873); the same was seen for corrected magnesium. There is insufficient evidence to demonstrate a significant statistical difference between those with and without DSPN in relation to glycemic control (HbA1c and FBS). Likewise, there is no significant statistical correlation between serum magnesium levels with HbA1c, FBS, BMI, or duration of diabetes. Conclusion This present study could not demonstrate any association between DSPN and serum magnesium, even after adjusting for age, sex, and comorbidity.
