The cases presented here indicate that disease progression and relapse may be associated with selective outgrowth of a specific FLC producing clone. [learningcenter.ehaweb.org]

• Weight Gain

  Four weeks later, the patient presented with a 20-lb weight gain and generalized swelling. He had no new symptoms other than discomfort from fluid retention. The review of systems at the time was entirely negative. [cjasn.asnjournals.org]

• Hypophonia

  Examination showed hypophonia, mild macroglossia, tongue stiffness, submandibular and submental musculature stiffness, firm sternocleidomastoids, generalized 4-extremity weakness, and bilateral thenar atrophy. [neurology.org]

  Liver dysfunction can also occur, with progression to hepatic failure. Other symptoms of LCDD relate to congestive heart failure, peripheral neuropathy, and skin lesions secondary to the deposition of light chains. [emedicine.medscape.com]

• Skin Lesion

  Peripheral neuropathy with pain, loss of sensation or an inability to control muscles can develop if the nervous system is involved, and if light chains are deposited in the skin, lesions can appear. [davita.com]

  No sign and symptom of liver or neurological involvement was found, none the less, maculopapular skin lesions were noted in case N02 which may be the sign of cutaneous deposits as described by some authors [ 9, 13, 14 ]. [omicsonline.org]

Extensive workup showed a faint gamma region band (SPEP); free kappa light chains (urine IFE); kappa level 4165 with kappa/lambda ratio 737.17 (serum free light chains); generalized myopathic MUAPs with fibrillations (EMG), and severe bilateral CTS (EMG [neurology.org]

On the other hand, the FLC ratio is abnormal in all patients with LCDD, 1, 6, 7 suggesting that serum FLC measurement should be performed in the diagnostic workup of adults presenting with renal disease, independent of the presence of a serum or urine [bloodjournal.org]

Laboratory Studies The laboratory workup for light-chain deposition disease (LCDD) includes the following: Routine serum chemistries to evaluate hepatic and renal function Complete blood cell (CBC) count to assess for anemia Serum and urine electrophoresis [emedicine.medscape.com]

• Albuminuria

  Albuminuria is not correlated with the existence of NGS, at least initially, and may occur in the absence of significant glomerular lesions by light microscopy. [jasn.asnjournals.org]

  Albuminuria levels do not correlate with the presence of glomerulonephritis and can be present even without glomerulosclerosis. [10] Renal function declines rapidly as a rapidly progressive glomerulonephritis or acute tubulointerstitial nephritis. [4] [emedicine.medscape.com]

  Severe albuminuria is the rule. Nephrotic syndrome is present in approximately 30% of cases, and microscopic hematuria is common. Hypertension occurs frequently and may be severe, as in this case. [cjasn.asnjournals.org]

• Creatinine Increased

  During the investigation period the serum creatinine increased to 288 μmol/l and the creatinine clearance declined to 16 ml/min. [academic.oup.com]

The treatment continued with hemodialysis 3 times per week with chemotherapy protocol bortezomib, doxorubicin, dexamethasone. [ncbi.nlm.nih.gov]

Treatment may include chemotherapy with a drug called Bortezomib ; autologous stem cell transplantation ; immunomodulatory drugs; and/or kidney transplant. [rarediseases.info.nih.gov]

This case supports the observation of Hobbs that patients with Bence-Jones myeloma may have a poorer prognosis than those with otherwise typical IgG or IgA myeloma. [ncbi.nlm.nih.gov]

Myeloma tubulopathy lesions may be present and in this case seems to be associated with a poor prognosis. Despite its rarity, the prognosis of this disease is poor because as than half of the patients die or progress toward ESRD within 2 years. [omicsonline.org]

Although the prognosis for long term kidney health is poor, there are some studies which have shown that some patients have done relatively well. [unckidneycenter.org]

Although renal prognosis is poor, patient survival can be considerable with 70 and 37% 5-yr patient survival and renal survival, respectively ( 36 ). [jasn.asnjournals.org]

Experiments have demonstrated that SecB does not recognize leader peptides at all [ Randall 1990 ], but instead recognizes some feature of incompletely folded MBP, which vanishes in the mature MBP, and that SecB and the leader peptide each serve to prevent [cureffi.org]

In order to prevent further progression of his renal disease, the patient was treated with 3 cycles of VAMP chemotherapy (vincristine 0.4 mg/day for 4 days, doxorubicin 9 mg/m 2 /day for 4 days and methylprednisolone 1 g/m 2 for 5 days per cycle). [wikilite.com]
