• 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

  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]

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]

Testing for the level of ALP (an enzyme called “alkaline phosphatase”) should be included in your regular blood lab workup. An ALP test measures the amount of this enzyme in the blood. [amyloidosis.org]

  The differential diagnosis of nodular glomerulosclerosis includes diabetes mellitus, amyloidosis, cryoglobulinaemia and LCDD. [academic.oup.com]

  Nodular glomerulosclerosis is the characteristic lesion of LCDD but not universal to this condition, since it is present in less than 50–60% of patients [3]. [kidneypathology.com]

  In the control series, it was found essentially in nodular diabetic glomerulosclerosis, which may suggest that distinct initial insults to the glomerular mesangium may trigger similar fibrogenetic pathways. [jasn.asnjournals.org]

  About 50% of patients with LCDD have concurrent myeloma, however most present with nephrotic range proteinuria and rapidly deteriorating renal function. 1 Renal biopsy shows nodular glomerulosclerosis, resembling diabetic kidney changes, and linear deposits [doi.org]

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

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

Fewer mature plasma cells indicate a poorer prognosis. Bone marrow microvessel density: A high degree of new blood vessel development in the bone marrow indicates active tumor growth and thus a poorer prognosis. [emedicinehealth.com]

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]
