Ultrastructural pathology of nephropathies with organized deposits: a case series.

Fabbian F, Stabellini N, Galdi A, Sartori S, Aleotti A, Catizone L - Cases J (2008)

Bottom Line: It has been suggested that immunoglobulins (Igs) are responsible for organized deposits.Proteinuria was detected in all patients while monoclonal component was present only in the serum of one subject.Diagnoses that were made are the following: membranoproliferative glomerulonephritis with finger print, immunotactoid glomerulopathy, membranoproliferative glomerulonephritis with arched deposits, primary amyloidosis and light chain deposition disease.

ABSTRACT
Renal organized or structured deposits are much less frequent than those with usual type immunocomplex deposits and are encountered in a wide variety of primary and systemic disorders. It has been suggested that immunoglobulins (Igs) are responsible for organized deposits. We report 5 cases who have been diagnosed and treated in our hospital. Patients were aged 52 to 72 years, three of them were males and had variable degree of renal function, from normal serum creatinine to uraemia. Proteinuria was detected in all patients while monoclonal component was present only in the serum of one subject. Ultrastructural analysis of renal specimens revealed organized deposits. Diagnoses that were made are the following: membranoproliferative glomerulonephritis with finger print, immunotactoid glomerulopathy, membranoproliferative glomerulonephritis with arched deposits, primary amyloidosis and light chain deposition disease. In systemic disorders ultrastructural pathology could be particularly valuable for correct deposits classification, precise localization and pattern of deposition of Igs.

Figure 3: Randomly distributed, non-branching fibrils (magnification ×15000).

Mentions: A 63-year-old Caucasian man was admitted because of nephrotic syndrome and renal failure (serum creatinine 1.6 mg/dl). Proteinuria was 8–9 g/24 h and Bence Jones proteinuria was positive. Renal biopsy showed massive amyloid deposition and fibrils infiltrating various renal compartments (Figure 3). Primary amyloidosis was diagnosed.
