Overview
Familial partial lipodystrophy related to perilipin 1 (PL-1) is a genetic disorder characterized by selective loss of adipose tissue primarily from the limbs and trunk, often accompanied by metabolic complications such as insulin resistance and diabetes. 1Diagnosis
Retinal examination for pigment alterations, drusen, and subretinal neovascularization 1
Serum complement levels, particularly C3, to assess dysregulation of the alternative complement pathway 1
Exclusion of membranoproliferative glomerulonephritis through appropriate renal function tests 1Management
Lifestyle modifications including diet and exercise to manage metabolic complications 1
Insulin sensitizers such as thiazolidinediones (e.g., pioglitazone) for managing insulin resistance 1
Regular monitoring of cardiovascular risk factors and lipid profiles 1Special Populations
Pregnancy: Limited data; close monitoring of metabolic parameters and complications recommended 1
Pediatrics: Early intervention focusing on lifestyle modifications and metabolic support crucial 1
Elderly: Increased vigilance for age-related complications such as retinal changes mimicking age-related macular degeneration 1
Comorbidities: Special attention to renal function and complement pathway dysregulation in patients with potential renal involvement 1Key Recommendations
Regular retinal evaluations are essential to detect early fundus changes indicative of age-related macular degeneration in PL patients, even without overt renal disease (Evidence: Moderate 1)
Assess serum C3 levels to evaluate complement pathway dysregulation in patients with familial partial lipodystrophy (Evidence: Moderate 1)
Implement comprehensive metabolic management including insulin sensitizers to address insulin resistance and associated metabolic issues (Evidence: Expert opinion 1)References
