Chronic renal failure after Puumala virus infection

Chronic renal failure has never been described after Puumala hantavirus infection, which usually causes acute renal failure with spontaneous full recovery. We report a 15-year-old boy who presented with Puumala hantavirus infection and initial severe acute renal failure. His renal function gradually improved, but more than 2 years after the acute episode it was still moderately impaired, with a creatinine clearance of about 60 ml/min per 1.73 m² Received: 25 June1998 / Revised: 19 February 1999 / Accepted: 19 February 1999     

Renal involvement in children with malignancies

 Renal complications in children with malignancies primarily arise from renal parenchymal tumors, ”tumor lysis syndrome,” and malignant infiltration or obstruction of the urinary tract. Therapy-associated renal side effects may develop following surgical and cytostatic treatment or be induced by radiotherapy. Clinically, both acute renal failure, for example following cisplatin, or chronic dysfunction, following ifosfamide and resulting in growth failure, are observed. Frequencies of renal impairment in these patients are, however, not well established, but terminal renal failure is a rare event: pediatric malignancies account for only 0.9% of patients on renal replacement therapy; the majority of these patients had been treated for a bilateral nephroblastoma. Since potentially serious long-term renal sequelae may evolve following both single measures and additive nephrotoxic effects, long-term monitoring of growth, blood pressure, and renal function is mandatory for a great proportion of former pediatric oncology patients. Future research should prospectively address frequencies of long-term renal impairment in these patients and should establish the prognosis of renal dysfunction. Only these data will ultimately allow risk-adopted use of potentially nephrotoxic treatment modalities and adequate counselling of patients.

Insuffisance rénale aiguë révélatrice d’un lymphome rénal. À propos d’un cas

Acute renal failure, as the initial manifestation of lymphoma, has been reported only in a few cases. In this work, we report the case of a 28-year-old women admitted for acute renal failure. Her physical examination detected bilateral kidney enlargement. Laboratory evaluation revealed a serum creatinine value 218 μmol/l. A 24-hour urine collection analysis allowed the detection of 1 g of protein. No red cells were found after urinanalysis. Renal ultrasound showed massively enlarged kidneys. Renal biopsy of the kidney and pathologic examination showed diffuse infiltration of the interstitium with lymphocytes and atypical cells positive for CD20 markers. A diagnosis of diffuse large B-cell type non-Hodgkin lymphoma was made. However, investigations revealed the presence of two others sites of lymphoma: gastric and ophthalmic. The patient's renal function and kidney size as well as the other lymphoma locations were normalized after the initiation of chemotherapy.     

Burkitt lymphoma arising in organ transplant recipients: a clinicopathologic study of five cases

We report five cases of Burkitt lymphoma arising in organ transplant recipients. There were four men and one woman with a mean age of 35 years. All were solid organ recipients with three renal, one liver, and one double lung transplantation. The time interval between organ transplantation and lymphoma averaged 4.5 years. Patients typically presented with high-stage disease with generalized lymphadenopathy and bone marrow involvement. Histology showed classic Burkitt lymphoma or atypical variant/Burkitt-like morphology. C-MYC rearrangement, including three cases with immunoglobulin heavy chain and two cases with lambda light chain, and Epstein-Barr virus were detected in all the cases. Additional chromosomal abnormalities were present in two of three cases and p53 mutation was found in one of three cases. Aberrant genotype and phenotype were frequently encountered, including minor monoclonal or oligoclonal T-cell populations and undetectable surface immunoglobulin light chain expression. Four patients received antilymphoma regimens, with combination chemotherapy (three patients) and/or Rituximab (three patients), in addition to reduction of immunosuppression. All four patients achieved complete remission. We conclude that posttransplant Burkitt lymphoma represents a characteristic clinicopathologic entity and occurs later after transplantation. Genotypic and phenotypic aberrations are often present. Rituximab may be an effective alternative to conventional combination chemotherapy in the treatment of a posttransplant Burkitt lymphoma.     

Transient acute renal failure due to nitrofurantoin poisoning

A 3-year-old girl developed acute oliguric renal failure after accidental ingestion of nitrofurantoin (190 mg/kg body weight). The time interval between poisoning and the onset of renal failure was 9 days. She later recovered with symptomatic management.

Ketorolac-induced irreversible renal failure in sickle cell disease: a case report

 Nonsteroidal anti-inflammatory drugs are often used in the management of those with acute pain secondary to sickle cell disease due to potent analgesic effects along with a lack of addictive potential, respiratory depression, and central nervous system effects, as may occur with narcotics. Caution should be observed in the use of nonsteroidal anti-inflammatory drugs in patients with compromised renal function. We present a case of a 17-year-old sickle cell disease patient with an acute painful episode and normal renal function indices who subsequently developed irreversible renal failure and a perirenal hematoma following the administration of ketorolac, despite adequate hydration. Due to its inhibitory effect on prostaglandin-mediated vasodilation, we advise caution in the use of ketorolac for the pain management of sickle cell painful episodes. We recommend following the administration guidelines for ketorolac for renal-compromised patients in those with painful episodes of sickle cell disease, and if used in this patient population, renal function must be very closely monitored.

Acute renal failure due to focal necrotizing glomerulonephritis in a patient with non-Hodgkin's lymphoma. Resolution with treatment of lymphoma

Renal disease in association with lymphoma is more prevalent than generally recognized. Glomerulonephritis may occur as a paraneoplastic phenomenon. We report a patient who presented with acute renal failure due to focal necrotizing glomerulonephritis in association with non-Hodgkin's lymphoma in whom the acute renal failure and glomerulonephritis resolved on clinical, biochemical and histological grounds with treatment of the lymphoma. Focal necrotizing glomerulonephritis is extremely uncommon in association with lymphoma and, to our knowledge, this association with follow-up and histological resolution of glomerulonephritis has not previously been reported.     

Acute renal failure in a patient with hemophagocytic syndrome

Acute renal failure (ARF) occurred in a 47-year-old man with hemophagocytic syndrome. Histological findings of the kidney revealed diffuse infiltration of interstitium by phagocytosing cells mixed with atypical lymphoid cells of varying size. The cytological features of the lymphoid population in liver and spleen were consistent with a diagnosis of peripheral T-cell lymphoma. We believe that this ARF could have been exacerbated by the interstitial infiltration of phagocytosing cells, reactive lymphoid cells, and T-cell lymphoma cells.

Burkitt lymphoma masquerading as cardiac tamponade

A 61 year old man presented with diffuse large B cell lymphoma of the skin of the back of the shoulder which was excised and treated with chemotherapy (CHOP regime) in 1998. He was in complete remission till he presented in 2002 with extranodal marginal zone lymphoma of the parotid gland for which he underwent superficial parotidectomy and radiotherapy. He continued in remission till 2006 when he presented with recurrent pericardial effusion and tamponade. At median sternotomy, pericardial effusion was drained, an anterior pericardiectomy was done and a left posterior pericardial window made, and an enlarged hard paraaortic lymph node excised. Histology, immunocytochemistry and chromosome analysis revealed Burkitt lymphoma. Patient underwent chemotherapy with CODOX-M regime and continues in remission. This report is unusual on account of the highly atypical presentation of Burkitt lymphoma as cardiac tamponade, only a few cases having been reported previously, the occurrence of three lymphomas of different pathological and genomic profiles in one patient over a period of eight years and the relatively slow rate of growth of an otherwise fulminant tumour with high tumour doubling time. A review of literature with special emphasis on chromosomal diagnosis, transformation of other lymphomas into Burkitt lymphoma and mediastinal and cardiac involvement with Burkitt lymphoma is presented.     

Regulation of cell survival during renal development

Apoptosis occurs in an orchestrated fashion during kidney development. In contrast, it is a relatively rare event in normal developed (adult) kidney. However, a predictable pattern of apoptosis is observed in adult kidney in two settings, during which parts of the developmental pattern are recapitulated. These are regeneration following acute ischemic injury and the process of cystogenesis in polycystic kidney disease. Apoptosis in kidney is regulated by agents both intrinsic and extrinsic to the renal cell. The protooncogene b-cell lymphoma/leukemia gene product-2 (bcl-2) is an important intrinsic factor. The growth factor epidermal growth factor is an important extrinsic regulator. A thorough understanding of the control of renal apoptosis during development and recovery from ischemic injury and in cystogenesis may lead to new therapies to prevent or ameliorate abnormalities of kidney formation, to enhance regeneration following acute ischemic injury, and to slow the progression of renal failure in polycystic kidney disease.

Acute renal failure due to non-Hodgkin lymphoma infiltration of the kidneys detected by ultrasonography and confirmed by positron emission tomography

Acute renal failure (ARF) as a consequence of non-Hodgkin lymphoma infiltration of the kidneys (LIK) is an uncommon complication of non-Hodgkin lymphoma. In literature, ARF due to LIK is reported in progressive disease. A case of non-oliguric acute renal failure secondary to relapse of large B cell non-Hodgkin lymphoma primarily localized in the mediastinum is reported. LIK of both kidneys was diagnosed by ultrasonography, computer tomography scan and 18-fluorodeoxyglucose positron emission tomography. No other causes for renal failure were found. The prognosis of renal involvement in relapsed non-Hodgkin lymphoma is poor, as is demonstrated by our case.     

Renal infiltrate by a plasmocytoïd chronic B lymphocytic leukaemia and renal failure: a rare occurrence in nephropathology. A case report and review of the literature

We report the case of a 55-year-old male with renal failure as the initial manifestation of interstitial and focal infiltration of the kidneys by a small B-cell lymphoma. Since three years, this patient had a history of CLL with plasmocytic differentiation and was left untreated owing to stade A Binet classification. After chemotherapy, the lymphocytosis and the adenopathies disappear and the renal function improve. Infiltration of the kidneys by non-Hodgkin small B-cell lymphoma, including chronic lymphocytic leukaemia (CLL), is usually asymptomatic, fortuitously discovered at the time of an X-ray examination or at autopsy. Association with renal failure is extremely rare. We review the reported cases of renal failure associated with lymphomatous infiltration (13 cases of CLL and five cases of lymphoplasmocytic lymphoma kappa or lambda IgM), with the following conclusions: in most cases, renal insufficiency appears in a few months and significantly disappears after chemotherapy; the renal infiltrate is usually focal in lymphoplasmocytic lymphoma and rather massive and diffuse in CLL; the neoplastic feature of a small B-cell lympho?d infiltrate may be difficult to determine: a poorly limited, monomorphous, CD20+ CD5+ lymphoid infiltrate is lymphomatous. In case of plasmocytic differentiation, it must be looked for kappa or lambda monotypy; the type of the lymphomatous infiltrate according to the WHO 2008 classification may be difficult to determine in a small sampling of renal tissue: the renal infiltrate must be compared, if possible, with a lymph node infiltrate. Owing to its bad prognosis, mantle cell lymphoma must be distinguished from other small B-cell lymphoma like CLL/small lymphocytic lymphoma, marginal zone lymphoma and lymphoplasmocytic lymphoma.     

Successful delayed bilateral renal revascularization during active phase of Takayasu's arteritis

Successful bilateral renal revascularization was performed 24 days after the development of angiotensin converting enzyme-inhibitor–induced bilateral renal artery thrombosis and anuric acute renal failure in a patient with Takayasu's arteritis. Excellent results were obtained after an unusually long ischemic time for a patient with active-phase disease. The outcome suggests that aggressive surgical revascularization can benefit patients with renal failure caused by renal arterial occlusion during the active phase of Takayasu's arteritis.

Acute non-dilating obstructive renal failure in a patient with AIDS

A 30-year-old male who presented with acute renal failure was found to have acquired immunodeficiency syndrome (AIDS). Although sonography and computerized tomography did not show urinary tract dilatation, obstructive renal failure was demonstrated by retrograde pyelography. Relief of obstruction(s) due to encasement of the renal pelves and ureters with histiocytic lymphoma led to immediate return of normal renal function. Although the etiology of renal failure in this patient is highly unusual, the high incidence of lymphoma in patients with AIDS should make tumor-related renal disease a consideration in all such patients with renal dysfunction.     

Early renal involvement in acute lymphoblastic leukemia and nonHodgkin's lymphoma in children

Clinical manifestations of kidney disease, particularly renal failure, caused by malignant infiltration in patients with acute lymphoblastic leukemia or nonHodgkin's lymphoma have been described rarely. We report 1 case of acute lymphoblastic leukemia and 3 cases of nonHodgkin's lymphoma in which renal disease was the only or one of the presenting manifestations of malignancy. Of these patients 2 had rapidly progressive renal failure with nephromegaly, 1 presented with bilateral abdominal masses caused by severe nephromegaly and with microscopic hematuria, and 1 had microscopic hematuria without nephromegaly. In all 4 patients kidney biopsy revealed malignant infiltration. In the 2 patients who presented with renal failure kidney function promptly returned to normal after chemotherapy and irradiation of the kidneys. Prompt and correct diagnosis of nephropathy, when it is the only or one of the presenting signs of acute lymphoblastic leukemia or nonHodgkin's lymphoma, is necessary to expedite initiation of specific antitumor therapy.     

Diagnosis and characterization of non-Hodgkin's lymphoma in a patient with acute renal failure

This case illustrates the relatively rare occurrence of malignant lymphoma presenting as acute renal failure due to renal parenchymal infiltration. To our knowledge, it is the first report in which the phenotype of a non-Hodgkin's lymphoma was established using renal biopsy tissue. The dangers of treatment of renal lymphoma in the patient whose disease has not been adequately characterized have been noted by Coggins.     

A family with nephronophthisis – medullary cystic disease complex

We report a family with nephronophthisis-medullary cystic disease complex (NPH-MCD). Case 1 was a 12-year-old girl with normal growth and development, who showed anemia and proteinuria at a health screening. A renal biopsy specimen showed chronic tubulointerstitial nephritis. Her renal function progressively decreased, and maintenance hemodialysis was started in January 1989. Case 2, the 29-year-old elder brother of case 1, had had anemia for 9 years and visited our hospital with symptoms of a common cold. Examination showed that he had chronic renal failure. A renal biopsy specimen showed chronic tublointerstitial nephritis. Case 3, a 27-year-old man, a first cousin of case 1, had had anemia for 1 year and was admitted to our hospital because of acute cardiac failure associated with chronic renal failure. Hemodialysis was started immediately. Two other people in the same family had chronic renal failure. Typing of the histocompatibility leukocyte antigen (HLA) was performed in four members of the family, but the results showed that there was no involvement of HLA in the pathogenesis of NPH-MCD.

Burkitt Lymphoma Mimicking an Acute Appendicitis in a 17 Years Old Boy: a Case Report

Burkitt lymphoma belongs to the B cell non-Hodgkin tumors and is known as the fastest growing human tumor. It is mostly seen in children and young adults. Typically for this type of lymphoma is the chromosomal translocation that leads to a deregulated expression of the c-myc oncogene.

Our case report describes a 17 year old patient who presents with atypical right lower quadrant pain. He underwent an explorative laparoscopy and a Burkitt lymphoma was discovered. Subsequently several imaging studies were performed to stage the disease. Intensive systemic chemotherapy is the choice of treatment. Surgery can have a role in early stages and acute complications of the tumor but frequently the role of surgery is restricted to histological biopsy.     

An unusual cause of acute renal failure: renal lymphoma

Renal involvement is a common finding in non-Hodgkins lymphoma (NHL). Acute renal failure at initial presentation due to lymphomatous infiltration of the kidneys has been described infrequently. We report a 17-year-old male who presented with acute renal failure due to massive lymphomatous infiltration of the kidneys, which necessitated hemodialysis. The diagnosis of B-cell NHL was established by tru-cut biopsy of the kidneys and the patient had an excellent response to high-dose chemotherapy with no major complication. The presence of extrarenal involvement in the testes and the retroperitoneal lymph nodes made the diagnosis of primary renal lymphoma debatable. However, considering the delay in diagnosis and the high proliferative rate of B-cell NHL, we might postulate that the disease had originated primarily in the kidneys. We recommend that in NHL cases with severe renal involvement, full-dose chemotherapy should be instituted with meticulous clinical and laboratory follow-up in order to improve clinical and renal failure status rapidly and to avoid further dissemination of NHL.     

The Lack of Clinical Value of Laboratory Parameters in Predicting Outcome in Acute Renal Failure

In 55 patients with either the oliguric and nonoliguric form of acute renal failure, some laboratory parameters for the analysis of prerenal and intrinsic types of acute renal failure were examined. The parameters were analyzed within 7 days of the clinically known beginning of the illness. The parameters were analyzed as follows: sodium in urine, creatinine urine/plasma ratio, urine osmolality, osmolality urine/plasma ratio, renal failure index, and fractional excretion of filtered sodium. Hemodialysis was performed in 29 of the 55 patients. The oliguric form of acute renal failure was present in 49 of the 55 patients. In relation to renal failure index, prerenal acute renal failure was present in 7 patients and intrinsic acute renal failure in 48. It appears that in patients with a clinical diagnosis ofprerenal acute renal failure, the urinary parameters do not separate them from those with acute tubular necrosis. It also appears that in patients with laboratory diagnosis of prerenal acute renal failure (i.e., a RFT < 1.0), the response to treatment is unpredictable and in fact may have a worse prognosis than in those with a RFI > 1.0 (5/7 deaths vs 10/48 deaths).
