Original ArticleKidney disease in patients with obesity: It is not always obesity-related glomerulopathy alone
چکیده انگلیسی


- Patients with obesity are at risk for chronic kidney disease but no large biopsy studies are available to indicate cause.
- Smaller studies describe an entity, obesity-related glomerulopathy, seen in patients with obesity without comorbidities.
- This is the first, large biopsy study showing the full range of pathology in patients with obesity and clinical renal disease.

SummaryObjectivePatients with obesity are at risk for chronic kidney disease. The aim is to characterize the spectrum of kidney disease in these patients, which may be related to obesity, termed obesity-related glomerulopathy (ORG), or may have other diseases secondary to associated or unassociated medical conditions.MethodsNative kidney biopsies from 2000 to 2012 were retrospectively reviewed from all patients with body mass index >30 kg/m2. Glomerular diameter was measured using a standard micrometer and clinicopathologic characteristics were analyzed.Results4% (287) of all biopsies were obtained from patients with obesity (mean: weight 122 kg, BMI 40.4 ± 7.35 kg/m2) for proteinuria in 93% and renal insufficiency in 53%. Frequent associated factors were abnormal glucose metabolism (31%), hypertension (60%), and obstructive sleep apnea (9%). Typical lesions of ORG were seen in 41% of cases and additional diseases in the rest. Glomerulomegaly, glomerular diameter >180 μm, was present in 84% of cases (mean 224 μm) vs normal size in 11% (mean 157 μm), but was not increased with higher magnitude of obesity. Proteinuria was highest in patients with idiopathic FSGS (mean 8 g/24 h) and immune complex diseases (mean 7.4 g/24 h) and was mainly subnephrotic in obesity-related FSGS and tubulo-interstitial diseases. Creatinine levels were highest in tubulointerstitial diseases (mean 8.4 mg/dL) and progressive diabetic nephropathy (mean 2.5 mg/dL).ConclusionsDiverse kidney pathology superimposed on ORG is present in patients with obesity with varied clinical renal disease, some of which may be amenable for therapy. Kidney biopsy will assist in delineating these lesions for appropriate management and prognosis.
