In this retrospective single-centre study, 96 consecutive
myeloma
patients were treated with melphalan 200 mg/m(2) with blood stem cell support as first-line therapy. Their mean age was 55 (38-65) years. The impact of renal function on stem cell collection yield, engraftment, transplantation-related toxicity and overall survival was studied. Glomerular filtration rate (GFR) was evaluated by iohexol clearance, a median 32 days before high-dose administration.
Chronic renal failure
(GFR <60 ml/min) was present in 19 patients, with severe failure (GFR <30 ml/min) in five patients, including one patient on haemodialysis. No relationship between GFR and stem cell collection yield or engraftment was observed, nor was the incidence of neutropenic fever or infectious complications related to GFR. Patients with subnormal renal function, however, were more often affected by severe mucositis. In addition, the two patients with severe GI bleeding, the two pneumonia patients who needed ventilator support and the only therapy-related death were noted in the five patients with severe renal failure. Lower iohexol clearance at the time of high-dose administration was found to have a poor impact on survival. A reduction of melphalan dose in patients with severe renal failure, here defined as iohexol clearance <30 ml/min, is suggested.

This study among elderly renal Egyptian patients (n=220) with only 20 of them were subjected to renal biopsy. Results showed: diabetic nephropathy in 28.2%, hypertensive nephrosclerosis 25.5%, UTI, cystitis and pyelonephritis in 6.8%, renal stones in 5.9%, obstructive uropathy in 7.6%, simple cysts in 4.5%,
CRF
of unknown origin in 13.1%, and others in 26.4%. DM and HTN were S related to kidney function tests and increase in elderly. Other cardiovascular risk factors and smoking are reported by previous workers to be HS related to renal diseases. Age was significantly related to GFR, BUN and Cr. but sex difference was not significantly related to renal diseases.
Multiple myeloma
, lupus nephritis, vasculitis and hepatitis B were all recorded in few numbers of elderly Egyptians. HCV was more common and more likely to cause renal diseases. Abdomino-pelvic ultrasound was confirmatory to clinical renal diseases diagnosis. Among patients (n=20) biopsies showed focal necrotizing GN in 20%, membranous nephropathy in 50% and renal amyloidosis in 30%. CTIN was associated in some cases due to NSAID intake. Analgesic nephropathy was a common problem that might lead to ARF in some cases especially in the elderly. Ultrasound results among the biopsy group were confirmatory to clinical diagnosis.

Multiple myeloma
(MM) associated with renal failure carries a worse prognosis when compared with MM without renal failure. Bortezomib, a reversible proteosome inhibitor, is a new drug indicated for the treatment of refractory or relapsed
myeloma
. Published data on the use of bortezomib in patients with
myeloma
and renal failure are few. We report our experience with bortezomib and dexamethasone in 3 previously untreated and 1 relapsed patient with MM and renal failure. All patients achieved rapid improvement in their renal function as measured by serum creatinine levels with only 1-2 cycles of bortezomib (+/- dexamethasone), 3 of 4 patients had a near complete response and 1 patient had a partial response. The rapid reversal of renal dysfunction with bortezomib (+/- dexamethasone) treatment may be an effective strategy to prevent
end stage renal failure
in MM, thereby improving the morbidity and mortality in this otherwise poor prognosis subset of patients with
myeloma
.

The purpose of this study was to investigate the clinical value of plasma thrombomodulin (PTM) in different diseases or in different severity or complications of diseases, PTM in 979 patients and 60 healthy controls was determined by ELISA method. The results showed that the PTM level in the control group was 20.40 +/- 7.72 microg/L, there was no difference in sex and ages. In chronic primary glomerular disease, the PTM level in
chronic renal failure
(
CRF
) group was higher than that in non-
CRF
group (P < 0.01). PTM level > 70 microg/L was defined as its positive criterion. The sensitivity, specificity and positive predictive value in PTM were 85.7%, 82.4% and 77.8% respectively. The PTM level in septemia group was higher than that in non-septemia group (P < 0.01), the sensitivity, specificity and positive predictive value were 86.6%, 89.5% and 76.5% respectively (> 50 microg/L as its positive criterion). With respect of multiple trauma, the PTM level in multiple organ failare (MOF) group was higher than that in non-MOF group (P < 0.01), while the sensitivity, specificity and positive predictive value were 77.8%, 77.3% and 73.7% respectively (> 40 microg/L as its positive criterion). For systemic lupus erythematosus (SLE), the PTM level in the patients with albuminuria was higher than that in the patients without albuminuria (P < 0.01), and the sensitivity, specificity and positive predictive value were 77.8%, 92.3% and 93.3% respectively (> 35.54 microg/L as its positive criterion). For diabetes, the PTM level in complication group was higher than that in group without complications, the sensitivity, specificity and positive predictive value were 53.4%, 97.1% and 98.6% respectively (> 35.54 microg/L as its positive criterion). The PTM level in microangiopathy group was higher than that in macroangiopathy group (P < 0.01). The sensitivity, specificity and positive predictive value were 71.2%, 97.1% and 97.9% respectively. Acute leukemia (AL) and
multiple myeloma
(MM) had higher PTM level and PTM level was extremely high when renal failure developed (P < 0.01). As compared the acute stage with the restoration stage in stroke, pre-chemotherapeutics with post-chemotherapeutics in AL and MM, and pre-operation with post-operation in cancer, the PTM level was connected with clinical development. The PTM level in the patients with microangiopathy was higher than that in the patients with macroangiopathy (P < 0.01). The defined PTM level was higher than its normal upper limit as PTM positive criterion in microangiopathy diseases, the sensitivity, specificity and positive predictive value were 77.7%, 71.2% and 75.6% respectively. It is concluded that PTM level is a good criterion in evaluating the microangiopathy, and PTM is also a valuable indicator in prediction or assessment of the severity of diseases, or evaluation of therapeutic effectiveness.

In an 81-year-old patient with a history of long-standing stable
chronic renal failure
a diagnosis of
multiple myeloma
was made. After an initial chemotherapy, a therapy with intravenous pamidronate, 90 mg monthly, was initiated. After four years of well tolerated therapy, pamidronate was stopped and zoledronate, 4 mg intravenously every four weeks, was started. After approximately one year, an elevated plasma creatinine was noted for the'first time, progressing to
end stage renal failure
within the next months. At admission, besides end-stage renal failure, severe asymptomatic hypocalcemia was noted. Renal biopsy findings included severe tubulointerstitial damage compatible with drug-induced tubular injury. Prerenal and postrenal failure could be excluded as well as
myeloma
kidney. The diagnosis of zoledronate-associated end-stage renal failure was made and treatment with hemodialysis was started. Hypocalcemia was treated with calcium and vitamin D3 supplements. After two years of follow up, the patient still required hemodialysis.

Although generally well tolerated there have been a number of reports of acute deterioration in renal function with the use of intravenous immune globulin (IVIG). It is of generally limited duration and is self-limiting. We for the first time have described a patient with
multiple myeloma
and normal renal function who developed
chronic renal failure
shortly after IVIG treatment in a patient with no pre-existing renal disease. We would therefore recommend the cautious use of IVIG in patients with normal renal function or with pre-existing renal disease. Renal function should also be assessed both prior to and after application of IVIG.

This study describes a spectrum of renal diseases that can precede the diagnosis of
multiple myeloma
(MM). Patients presenting manifestations of renal disease were recorded as individual patients of MM. Fifty patients (male 41; female 9) were included in this study. Diagnosis of MM was confirmed by two or more of the following four features: lytic bone lesions, serum or urine monoclonal peak, Bence Jones proteinuria, and greater than 20% plasma cells in bone marrow. Renal disease was present in 42 of 50 (84%) patients before MM was diagnosed. In only eight of 50 (16%) patients, diagnosis of MM preceded the detection of renal disease. Renal diseases consisted of acute renal failure in 26 patients (52%),
chronic renal failure
in 15 patients (30%) and nephrotic syndrome in 9 patients (18%). Some of the patients with acute or
chronic renal failure
also had heavy proteinuria. Percutaneous renal biopsy was done in 17 patients. Renal histopathology showed amyloidosis (n = 10), cast nephropathy (n = 5), nodular glomerulosclerosis (n = 1), and mesangioproliferative glomerulonephritis with plasma cell infiltration (n = 1). Hypercalcemia (calcium 11-13.8 mg/dL) was the most common precipitating factor for acute renal failure. All 50 patients received combination chemotherapy of melphalan and prednisolone or vincristine, Adriamycin, and dexamethasone. More than half of the total number of patients did not complete chemotherapy because of death or lost to follow-up. Nineteen patients with acute renal failure and eight patients with
chronic renal failure
were treated with hemodialysis. Fourteen patients (28%) with acute renal failure had recovery of renal function. Twenty-three patients (46%) were lost to follow-up. Seven patients (14%) died from sepsis, uremia, or hyperkalemia. Remission of MM was found in 9 of 21 (42.8%) patients who completed chemotherapy. Thus, acute renal failure is the most common renal disease preceding the diagnosis of MM. Reversal of renal function is achieved with chemotherapy and hemodialysis treatment.

Dysproteinemias that result in monoclonal glomerular deposits of IgG are relatively uncommon. Here, we report the largest series of proliferative glomerulonephritis with monoclonal IgG deposits, a form of renal involvement by monoclonal gammopathy that mimics immune-complex glomerulonephritis. We retrospectively identified 37 patients, most of whom were white (81%), female (62%), or older than 50 yr (65%). At presentation, 49% had nephrotic syndrome, 68% had renal insufficiency, and 77% had hematuria. In 30% of the patients, we identified a monoclonal serum protein with the same heavy- and light-chain isotypes as the glomerular deposits (mostly IgG1 or IgG2), but only one patient had
myeloma
. Histologic patterns were predominantly membranoproliferative (57%) or endocapillary proliferative (35%) with membranous features. Electron microscopy revealed granular, nonorganized deposits, and immunofluorescence demonstrated glomerular deposits that stained for a single light-chain isotype and a single heavy-chain subtype, most commonly IgG3kappa (53%). During an average of 30.3 mo of follow-up for 32 patients with available data, 38% had complete or partial recovery, 38% had persistent renal dysfunction, and 22% progressed to
ESRD
. Correlates of
ESRD
on univariate analysis were higher creatinine at biopsy, percentage of glomerulosclerosis, and degree of interstitial fibrosis but not immunomodulatory treatment or presence of a monoclonal spike. On multivariate analysis, higher percentage of glomerulosclerosis was the only independent predictor of
ESRD
. Only one patient lacking a monoclonal spike at presentation subsequently developed a monoclonal spike and no patient with a monoclonal spike at presentation subsequently developed a hematologic malignancy. We conclude that proliferative glomerulonephritis with monoclonal IgG deposits does not seem to be a precursor of
myeloma
in the vast majority of patients.

We report here a 50-years old female with
multiple myeloma
-associated
chronic renal failure
who underwent high-dose chemotherapy supported by autologous hematopoietic stem cell transplantation. She developed progressive encephalopathy on day 5 progressing to coma despite hemodialysis and no obvious organ failure. She finally recovered after a single 1-liter plasma exchange. The final diagnosis was metabolic encephalopathy due to hypercytokinemia, particularly high serum TNF levels. We discuss here the pathogenesis and raise an alert for monitoring cytokine levels in patients with renal failure undergoing high-dose chemotherapy.

We analyzed 25 patients with
multiple myeloma
. All the patients fullfilled diagnostic criteria of International
Myeloma
Working Group (2003): presence of monoclonical protein in serum or/ and in urine (IgG 64%), IgA -16%, free light chains - 16%, in one patient (4%) biclonal typ plasmocytoma was diagnosed), at least 10% plasmocytes in the bone marrow and at list one evidence of end-organ damage such as anemia (92%), bone lesions (65%), hypercalcemia (36%) and renal insufficiency (92%). Acute renal failure was diagnosed in 60% of patients and 32% with
chronic renal failure
. Only 2 patients had normal renal function. 36% of patients required hemodialysis. Our analysis showed that almost all patients were admitted to hospital at a very advanced stage of the disease and renal failure was dominant, mostly at advanced stadium.
