Synonyms and keywords: light chain deposition disease

Overview

Localized deposition of fibrils and proteins in glumerole is called glomerular deposition disease.

Light chain deposition disease (LCDD) is one of the glomerular deposition disease. It's a rare blood cell disease which is characterized by deposition of fragments of infection-fighting immunoglobulins, called light chains, in the body. These light chain deposits damage organs and cause disease. The kidneys are almost always affected and this often leads to Chronic renal failure. About half of people with light chain deposition disease also have multiple myeloma. Unlike in AL Amyloidosis, in which light chains are laid down in characteristic amyloid deposits, in LCDD, light chains are deposited in non-amyloid granules. Light chains in LCDD are kappa light chains in granular shape[1].

Classification

Glomerular deposition diseases are classified in 5 types of diseases:

  1. LCDD
  2. Amyloidosis
  3. Fabry's disease
  4. Fibrillary immuno-tactoid glumerulopathy: The diagnosis is based on pathology finding. Infiltration of fibrills make glomerular structures in the kidney. Fibrills are larger than amyloid fibrils. Patients usually asymtomatic but, sometimes have proteinuria and hematuria. Prognosis is poor and ESRD will happen in half of the patients [2].
  5. Collagenofibrotic glomerulopathy: A rare disease and the diagnosis is based on pathology finding. Type III collagen fibers deposit in the subendothelial and mesangium in the kidney. Negetive with Congo red and thioflavin stains. There is no specific threatment for it[3] .

Pathophysiology

Pathogenesis:

Deposits of abnormal or extra production of proteins, lipids and fibrills in the glomeruls cause glomerular deposition diseases.

-In LCDD:

light chains are small polypeptides produced by B lymphocytes.They are sub units of antibodies. Kappa and Lambda are two types of light chains. Excess production of Kappa chain and accumulation in the renal glumerulus cause LCDD. The exact mechanism of increase production of light chains and reason that renal attracts them is unknown. These chains can deposit in all parts of renal glumeruls and tubuls.

Accumulation of monoclonal light chains and matrix proteins → ↑ quantity and activity of transforming growth factor-beta (TGF-beta). TGF-beta → inhibit mesangial cell proliferation and ↑ matrix protein production

Besides glumerulus,light chains may accumulate in renal tubulartubular casts→  interstitial inflammationrenal failure [5].

- In Amyloidosis:

  Amyloids (misfolding and aggregation of normally soluble proteins) deposit in the nephrones and cause renal failure.

- In Fabry's disease:

A deficiency of the enzyme alpha galactosidase A causes deposition of glycolipid in the nephrones and cause renal failure.

- In Fibrillary immuno-tactoid glumerulopathy:

Fibrills (larger than amyloids) deposit in subendothelial and mesangium of the nephrones and cause function impairment.

- In Collagenofibrotic glomerulopathy:

Type III collagen fibers deposit in the subendothelial and mesangium in the kidney.

- In Collagenofibrotic glomerulopathy:

  • Deposition of irregular collagenous fibers in the mesangium and subendothelial space of the renal glumerol [10].

Genetics

Causes

The specific etiology that cause extra or abnormal production of fibrills and chains in the glomerular depositional diseases is unknown.

Differentiating from Other Diseases

Epidemiology and Demographics

The incidence of glomerular deposition disease depends on the type of the disease. Collagenofibrotic glomerulopathy and Fibrillary immuno-tactoid glumerulopathy are rare. LCDD is unknown. Most of the patients are men with the mean age of 58 years [1]. The incidence of amyloidosis is 1.2 per 100,000 individuals per year [11]. The incidence of Fabry's disease is 1 in 50,000 males [12].

Renal involvement is the most common cause of mortality and morbidity in these patients. Survival varies between months to 10 years in patients with LCDD [13].

Risk Factors

There are no established risk factors for glomerular deposition disease.

Screening

There is insufficient evidence to recommend routine screening for glomerular deposition disease.

Natural History, Complications, and Prognosis

Prognostic factors of glomerular deposition diseases at presentation [1]:

The median time to progression to chronic renal failure in LCDD is 2.7 years. After 5 years, about 37% of patients with LCDD are alive and do not have end stage renal disease.

Diagnosis

Diagnostic Study of Choice

History and Symptoms

All organs can be effected by Glomerular deposition diseases especially in LCDD. Most of the time kidney is involved [15]. Usually patients are asymptomatic in early stages. Symptoms are nonspecific like fatigue and weight loss. Rapidly progressive glomerulonephritis or acute tubulointerstitial nephritis cause renal failure in these patients. Other than the kidneys, liver and heart are the most commonly involved organs. Deposition of light chains in the liver may lead to hepatomegaly, portal hypertension and liver failure. The heart is affected in up to 80% of patients with LCDD, and may cause arrhythmias restrictive cardiomyopathy, cardiomegaly, and congestive heart failure [16].

Physical Examination

Laboratory Findings

Electrocardiogram

Arrhythmia like atrial fibrillation ( in case of heart involvement).

X-ray

There are no pathognomonic and specific x-ray findings associated with LCDD.

Echocardiography or Ultrasound

  • Echocardiography:

In case of heart involvement: ↓ EF, diffuse hypokinesia, left ventricular concentric hypertrophy, ↓ diastolic compliance [18]

  • Ultrasound:

No findings associated with renal Glomerular deposition diseases.

CT scan

  • In severe cases the size of the organ will ↑.
  • No pathognomonic and specific finding associated with Glomerular deposition diseases.

MRI

  • In severe cases the size of the organ will ↑.
  • No pathognomonic and specific finding associated with Glomerular deposition diseases.

Other Imaging Findings

There are no other imaging findings associated with Glomerular deposition diseases.

Other Diagnostic Studies

There are no other diagnostic studies associated with Glomerular deposition diseases.

Treatment

Medical therapy:

70% of cases without therapy will have ESRD. There is no standard treatment for Glomerular deposition diseases. Medical therapy options for LCDD are:

Surgery

In case of ESRDKidney transplant

Primary Prevention

There are no established measures for the primary prevention of Glomerular deposition diseases.

Secondary Prevention

There are no established measures for the secondary prevention of Glomerular deposition diseases.
