Chemotherapy (Ctx) and/or radiotherapy (Rtx) are effective in the treatment of
Hodgkin's disease
(HD) but potentially involve late toxicities, including nephrotoxic side effects. Therefore a follow-up study has been performed to screen patients for late signs of an impaired tubular or glomerular function and to correlate data of renal function with type of therapy and cumulative doses of cytotoxic agents applied. 81 patients in complete remission for at least 2 years and a median follow-up of 96 (39-304) months, and 53 controls were examined. Clinical routine parameters such as creatinine and electrolytes were determined. A differentiation of
proteinuria
into the albumin, high molecular weight (HMW) and low molecular weight (LMW) fractions made it possible to assess glomerular and tubular function based on the LMW/HMW ratio. The structural protein fibronectin served as an additional, sensitive marker of glomerular integrity. Routine parameters of kidney function did not show any signs of late nephrotoxicity. However, patients treated for HD had a higher ratio of LMW/HMW in comparison to the group of healthy volunteers (p < 0.01), indicating subclinical tubular renal damage. When the cutoff for tubular damage was defined as LMW/HMW > 1.5, 50% of the patients treated with combined modality, and 42 and 37% of the patients with Ctx or Rtx alone had subclinical tubular alterations, respectively. A tendency towards a higher prevalence of subclinical tubular changes was observed in patients with higher cumulative doses of methotrexate or ifosfamide and in patients with combined Ctx and Rtx with radiation fields involving the renal area. Changes in glomerular function were not observed. It is concluded that treatment of HD is not associated with clinically apparent long-term impairment of renal function but can lead to subclinical alterations. Further clinical implications of these subclinical tubular alterations cannot be assessed at present. A differentiation of
proteinuria
does not have to be performed routinely but might be useful in the follow-up of selected patients with an increased risk.

A 15-year-old boy developed minimal change nephrotic syndrome (MCNS) during remission of
Hodgkin's disease
. Natural killer (NK) cell activity was practically absent at the onset of MCNS, with a value of 3% compared with the normal value of 44.1% +/- 7.8% (mean +/- SD). Treatment with prednisolone resulted in transient remission of MCNS and partial improvement of NK cell activity. Extensive investigations for
Hodgkin's disease
were performed at 1- to 3-month intervals; a relapse finally became apparent 25 months after the diagnosis of MCNS. Successful treatment of
Hodgkin's disease
resulted in complete disappearance of
proteinuria
and normalisation of NK cell activity. Frequently relapsing MCNS with NK cells deficiency during remission of
Hodgkin's disease
appears to imply its subclinical relapse.

Amyloidosis is considered rare but has an incidence similar to that of
Hodgkin's disease
and chronic granulocytic leukemia. The diagnosis should be considered in any patient with unexplained nephrotic-range
proteinuria
, heart failure, peripheral neuropathy, or hepatomegaly. If a monoclonal protein is found in a patient with any of these clinical presentations, a biopsy should be performed and the specimen stained with Congo red. The simplest source of diagnostic material is subcutaneous fat tissue. Treatment usually consists of chemotherapy, which may be oral and low dose or high dose with stem cell rescue.

Peripheral blood progenitor cell reinfusion (PBPC) in patients undergoing high-dose chemotherapy (HDC) for poor prognosis malignancies, has been described as causing possible acute gastrointestinal (nausea, vomiting), allergic (oedema, bronchospasm, anaphyl- axis), renal (
proteinuria
, haematuria) and/or cardiovascular (hypotension, arrhythmia, conduction disturbances, transient ischaemic phenomena) toxicities. To establish the clinical relevance of these observations and the possible relationship with different HDC regimens used, we performed a clinical and instrumental evaluation on 33 patients with advanced breast cancer, non-Hodgkin's lymphoma,
Hodgkin's disease
, relapsed ovarian cancer, Ewing's sarcoma, extragonadal germinal tumour and small cell lung cancer. They underwent at least one reinfusion each for a total of 51 studied procedures. No patient had a previous history of cardiovascular disease or significant intercurrent illness such as diabetes or liver, renal or neurologic impairment. All patients had totally implanted central venous catheters, through which the transplants had been collected and reinfused without technical consequences. To evaluate cardiovascular function, we continuously monitored 12-lead ECGs, with arterial pressure (AP) measurements every 5 min from the beginning of the procedure to 15 min after the reinfusion ended. We did not observe any significant differences between basal and subsequent steps in AP, heart rate, PQ and QTc time, P wave and QRS complex duration or P wave and QRS electrical axes. No patient showed any ST-T tract pathological abnormality, but one patient developed a transient ectopic atrial rhythm, without any haemodynamic disfunction and with spontaneous reversion to sinus rhythm. No patient complained of symptoms of haemodynamic failure. Gastrointestinal side-effects appeared to be strictly related to speed of reinfusion and to the number of packs reinfused, probably reflecting on the amount of dimethylsulphoxide infused. In one patient a tonic-clonic seizure occurred during a vomiting episode, but no patient developed allergic or renal toxicities. We conclude that PBPC reinfusion, if managed according to the procedure we propose in patients without organic impairment, is a safe procedure not associated either with increased risk of acute arrhythmias or ischaemic or significant systemic acute toxicities.

The purpose of this study was to investigate children followed as having both
Hodgkin's disease
(HD) and nephropathy and discuss the factors which might play roles in the pathogenesis of this association by reviewing the pertinent literature. Our experience among 661 children with HD revealed ten cases (1.5%) with nephropathy; eight of these were biopsy proven. Tissue diagnoses were amyloidosis (AA type) in four cases, and membranoproliferative glomerulonephritis and minimal change glomerulopathy in two cases each. Sex distribution was equal. There was a predominance of the mixed cellular (MC) histologic type in our patients with HD. Nephropathy was shown to antedate the diagnosis of HD in two cases and to herald a relapse in one. In brief, the development of a nephropathy in a patient with HD can be considered as a paraneoplastic phenomenon. Renal amyloidosis may already be present at the time of diagnosis of HD and must be kept in mind as a cause of
proteinuria
due to preexisting nephropathy. Developing renal paraneoplastic syndrome, even in early-staged HD, in children, may be a poor prognostic factor.

Small amounts of amyloid in kidney biopsy specimens may be missed on routine examination unless specifically targeted. Occasionally, this oversight results in a diagnosis of minimal change glomerulonephritis (MCGN). This misdiagnosis may be facilitated by the fact that typical "minimal changes" with flattening and effacement of the epithelial foot processes can be found in capillary loops directly affected by amyloid deposition as well as in capillary loops of glomeruli with only mild amyloid deposition in the mesangium. Repeatedly, the diagnosis of MCGN had to be corrected to renal amyloidosis when re-examination by special techniques succeeded in detecting even small amounts of amyloid fibrils. We present the case of a previously healthy 49-year-old man who suddenly developed nephrotic syndrome. A first renal biopsy showed MCGN.
Proteinuria
remained refractory to immunosuppressive treatments, and creatinine clearance deteriorated rapidly. Two years later, a repeat renal biopsy showed AL-amyloidosis. In this case, re-examination of the first biopsy in the light of the final diagnosis again did not show any deposition of amyloid fibrils. We suspect that
proteinuria
and epithelial podocyte changes in amyloidosis are caused by factors other than deposition of amyloid fibrils itself. Possibly a cytokine release during the early fibril formation leads to abnormalities even before the typical structural changes of renal amyloidosis can be detected. This is analogous to the hypothesis of a circulating factor that leads to
proteinuria
in focal segmental glomerulosclerosis or the speculation of altered lymphokine expression associated with the development of MCGN in
Hodgkin's disease
.

With the aim of developing an effective therapy for heavily pretreated refractory MM outpatients, we evaluated the OPPEBVCAD regimen, a
Hodgkin's disease
-derived protocol that includes many drugs effective in MM administered in a sequential schedule. Twenty-two pts aged 42-72 years, with symptomatic highly-pretreated refractory (18 cases), or primary resistant MM (four cases. including two pts with plasma cell leukemia-PCL) received this therapy every 28 days (2-4 cycles, followed by a maintenance program). Therapeutic response (Chronic Leukemia-Myeloma Task Force criteria) and performance status (PS) and pain (W.H.O.) were evaluated. All of the pts were evaluable for response. There were 9 (40%) objective responses (OR: stabilization of blood counts and bone lesions, serum calcium normalization, 50% or more reduction in the concentration of serum monoclonal component (MC), 90% reduction in Bence-Jones
proteinuria
), 8 (36%) partial responses (PR: 25-50% reduction in serum MC), 1 no response or stable disease (NR), and 4 (18%) cases of progressive disease (PD). OR plus PR were 77%. Of the 4 primary resistant tumors (2 PCL and 2 MM), 2 achieved PR, 1 OR (a PCL case) and 1 progressed. Median survival was 15 months for responding pts (OR plus PR) and 4.5 months for non-responders (NR plus PD). PS and pain improved in 15 pts and did not change in 9. The most frequent side effects were cytopenias, with one drug related infective death. The OPPEBVCAD regimen proved to be an effective therapy for refractory relapsing or primary resistant MM: in responders (two-thirds of the pts), survival was prolonged by about 10 months. Its efficacy in anthracycline-treated pts, as well as the feasibility of using it on an outpatient basis without any continuous drug infusions, make this regimen a promising third line salvage therapy.

Immunotactoid glomerulopathy is one of several renal disorders characterized by the extracellular deposition of nonamyloid fibrillary deposits. There is considerable debate as to whether immunotactoid glomerulopathy should be distinguished from fibrillary glomerulonephritis, a closely related entity. Currently, the distinction is based on fibril size and arrangement. We report the case of a 59-year-old woman in whom a diagnosis of immunotactoid glomerulopathy was made after a 2-year history of
proteinuria
. Electron microscopy of her renal biopsy showed randomly arranged microtubular subepithelial and mesangial deposits, which measured 34 nm in average diameter. She was later discovered to have circulating immunoglobulin G heavy chains without associated light chains (gamma-heavy-chain disease) and, subsequently, non-
Hodgkin lymphoma
, follicular lymphoma, grade I (World Health Organization classification). Approximately 100 cases of gamma-heavy-chain disease have been reported in the literature since it was originally described by Franklin in 1964. However, while there are 10 reports in the literature of heavy-chain disease with fibrillary deposits in the kidney, none fit the criteria for immunotactoid glomerulopathy.

Renal involvement with amyloidosis is common but causes patient survival to be poor, rarely reaching 5 years. In this study, we retrospectively reviewed clinical and biological characteristics as well as treatments and outcomes of patients with renal amyloidosis followed for more than 5 years. Between 1975 and 2003, 485 patients were diagnosed with renal amyloidosis including only 12 patients who were followed more than 5 years. The six men and six women of mean age 42.4 years (range 18 to 66 years) displayed renal signs of lower limb edema in all cases; hypertension in four cases,
proteinuria
on urinalysis in all cases with microscopic hematuria in five cases. Biological tests showed nephrotic syndrome in 11 patients, normal renal function in nine patients, and renal failure in three patients whose mean creatinine was 481.6 micromol/L (range 294 to 726). The amyloidosis was AA type in 11 cases and non-AA in one case. An etiologic survey revealed spondylarthropathy in one patient, pulmonary tuberculosis in two patients, chronic bronchitis in three patients, hepatic hydatic cyst in one patient, Mediterranean familial fever in two patients, Crohn's disease in one patient,
Hodgkin's lymphoma
in one patient, and multiple myeloma in one patient. Specific treatment was initiated with colchicine in seven patients. At a 110-month mean follow-up (range 53 to 153 months), remission of nephrotic syndrome was observed in four cases, progression to chronic renal failure in two patients, and to end-stage renal failure in five cases (range 53 to 196 months), with stabilization of renal function in seven patients. In conclusion, primary amyloid disease should be optimally suppressed in patients with renal involvement. The role of this treatment in remission of renal amyloidosis is not well established. This efficacy of the treatment has been demonstrated in some patients with improved survival.

We report a case of non-
Hodgkin lymphoma
(NHL) with acute renal failure. A 62-year-old man was admitted to our hospital on March 8, 2002 with leg edema and dyspnea on effort. About 3 weeks before admission, he was found to have slightly high serum creatinine (Cr) and high lactate dehydrogenase (LDH) levels by another home doctor. Physical examination revealed anemic conjunctivae and leg edema, but the urinary volume was preserved. Blood examination showed high BUN (64 mg/dl) and Cr levels (3.91 mg/dl). Urinary analysis showed
proteinuria
(1.05 g/day) and high BMG (14,434/microg/day) and NAG (4.55 U/day) levels, suggesting severe tubulointerstitial injury. On ultrasonography of the kidney, the bilateral kidneys showed marked swelling without hydronephrosis. To investigate the genesis of renal failure, we performed a renal biopsy. The specimen showed normal glomeruli, but a large number of cells infiltrated in the tubulointerstitial area with normal tubulointerstitial structure. The cells stained positively with anti-leukocyte antigen and L26 (B cell marker), and negatively with cytokeratin and UCHL-1 (T cell marker). These findings indicate that the interstitial cells were non-
Hodgkin lymphoma
with B cell diffuse large cells. Chemotherapy was performed with VAD (vincristine sulfate, doxorubicin hydrochloride, dexamethasone) considering his renal dysfunction. To avoid tumor lysis syndrome after chemotherapy, hemodialysis was performed on days 1-4 after the initiation of chemotherapy. After a series of chemotherapy, the urinary volume increased and serum Cr levels decreased to 2 mg/dl. After additional therapy with 4 courses of CHOP, he improved and was discharged on day 180 after admission.
