%X Background: In lupus nephritis (LN), glomerular dysfunction is evident by proteinuria. Urinary Neutrophil Gelatinase Associated Lipocalin (NGAL) has emerged as a promising biomarker to detect tubular dysfunction. Objective: To evaluate the tubulo-glomerular outcome after induction of Euro-Lupus regimen by measuring proteinuria and NGAL. Methods: This was a quasi-experimental study. Patients were included based on American College of Rheumatology (ACR) criteria. A total of 19 diagnosed lupus nephritis (class III & IV with or without class V) cases were evaluated. Their renal biopsy report was labelled according to the International Society of Nephrology/Renal Pathology Society (ISN/RPS). All patients were treated with low-dose cyclophosphamide (Euro-Lupus regimen) for three months. Patients were assessed at baseline and then monthly up to 3 months of induction. The observed major variables were complete blood count (CBC), lupus serology (ANA, anti-dsDNA, C3, C4, anti-phospholipid), 24-hour urinary total protein (UTP), spot urinary protein creatinine ratio (PCR), spot urinary NGAL, urinary NGAL creatinine ratio, serum creatinine, serum albumin and estimated glomerular filtration rate (e-GFR). The activity index (AI), chronicity index (CI) and disease activity over time (SLEDAI) were assessed accordingly. Results: Mean age of the study population was 29 ± 10 years, where 95.5% were female. After 3 months of induction with low-dose cyclophosphamide (Euro-Lupus regimen), hemoglobin, eGFR, and serum albumin level had significantly increased from baseline (p < 0.05), while serum creatinine, UTP, PCR, urinary NGAL and disease activity score were significantly decreased (p < 0.05). Complete response was seen in 26.3% study patients and partial response in 36.8% patients after 3 months of induction. Response did not differ significantly in this short period of treatment among different histological types of LN. Conclusion: Induction in lupus nephritis by low-dose cyclophosphamide (Euro-Lupus regimen) reduces proteinuria and urinary NGAL significantly after three months of therapy. This regimen is effective in improving glomerular and tubular dysfunctions of LN.
