Semaglutide-Associated Acute Interstitial Nephritis: A Case Report.

ABSTRACT: Glucagon-like peptide 1 receptor agonists (GLP-1RAs) are being investigated to slow the decline of kidney function in type 2 diabetics with chronic kidney disease (CKD). These agents have proven benefits on cardiac outcomes and all-cause mortality as well as in reducing the incidence of macroalbuminuria. Ours is a case of drug-associated acute interstitial nephritis requiring hemodialysis temporally related to a semaglutide dose increase. This case is unique as the index patient had no underlying CKD. Limited cases of acute kidney injury, superimposed on underlying CKD, in patients taking the GLP-1RA semaglutide have been reported. To our knowledge, there are no existing case reports in the literature of GLP-1RA-associated acute interstitial nephritis in a patient with baseline normal kidney function. Because our prescription of these agents is increasing and is anticipated to increase further with growing scientific evidence for their benefit, we sought to highlight this possible, important serious adverse effect of semaglutide.

Project description:Acute interstitial nephritis (AIN) has been recently recognized as one of the infrequent kidney involvement phenotypes among adult patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Although SARS-CoV-2 associated intrinsic kidney disease has been scarcely reported in children, only one case of AIN temporally associated with the infection has been described in the pediatric population so far. We presented a case of a 12-year old boy who presented with fatigue, anorexia, and polydipsia following an RT-PCR that confirmed SARS-CoV-2 infection seven weeks prior to admission. Initial workup revealed increased serum creatinine (235 μmol/L), glucosuria, low-molecular-weight proteinuria, mild leukocyturia, and microhematuria with hyaline and granular casts on microscopy. Antibodies against the SARS-CoV-2 S protein receptor-binding domain confirmed prior infection with high titers. Kidney biopsy showed diffuse active interstitial nephritis with negative immunofluorescence and positive immunohistochemistry for SARS-CoV-2 in the inflammatory cells within the interstitium. Electron microscopy revealed several SARS-CoV-2-like particles. Kidney function continued to deteriorate despite several days of supportive therapy only (peak serum creatinine 272 μmol/L); thus, treatment with methylprednisolone pulse-dose therapy was initiated and was followed by oral prednisolone with gradual tapering. Kidney function completely recovered after 3 weeks post-discharge and remained normal after 11 weeks of follow-up (last estimated glomerular filtration rate 106 ml/min/1.73 m2) with only residual microhematuria. Our case adds to the emerging evidence of SARS-CoV-2 as a potential etiological agent of AIN in children and also suggests that interstitial kidney injury may result from secondary inflammatory damage. Epidemiological history, serologic testing, and SARS-CoV-2 detection in biopsy should be considered in the work-up of children with AIN of unknown etiology.
