Idiopathic hematuria is a clinical condition of unknown etiology; it is defined as persistent or recurrent, macro or microscopic hematuria in the absence of systemic or local disease and with normal renal function. Six patients who had these criterions were studied. There were all girls. The age of the first episode was between one and four years. There was no other family or personal history of renal disease or deafness. Only two patients had their episodes of macroscopic hematuria within flu-like illness or exercise. All had normal renal function and no proteinuria was found. Serum C'3 and C'4 were normal. Microscopic and immunofluorescence studies were negative. We remark the convenience of a triple criteria clinical, histopathologic and evolutive to select a patient into the "idiopathic hematuria" group. We comment the usefullness of renal biopsy in the investigation of unexplained hematuria.

Before and four weeks after immunization with a single 0.5-ml dose of influenza virus vaccine, sera from 36 children with renal diseases were tested for serum hemagglutinating-inhibiting antibody (HAI) titers to A/New Jersey/76, A/Victoria/75, and A/Port Chalmers/73. Before immunization, 1:40 HI antibodies to A/New Jersey were noted in one child only, to A/Victoria in ten children (27%), and to A/Port Chalmers in 25/34 children (68%). Serum HAI titers increased fourfold or more (P less than .01) in 31/36 children (86%) after immunization. Neither the type of the renal disease nor therapy with prednisone had any effect on the rise of serum HAI titers (P less than .05). Of the seven children with preimmunization proteinuria, four had a transient rise in protein levels following immunization. None required an increased prednisone dose for exacerbation of nephrotic syndrome. Children with chronic renal problems should be protected against influenza.

Hantaviruses, the causative agents of HFRS, have become more widely recognized. Epidemiologic evidence indicates that these pathogens are distributed worldwide. People who come into close contact with infected rodents in urban, rural and laboratory environments are at particular risk. Transmission to man occurs mainly via the respiratory tract. The epidemiology of the hantaviruses is intimately linked to the ecology of their principal vertebrate hosts. Four distinct viruses are now recognized within the hantavirus genus and that number is likely to increase to six very soon; however, further investigations are necessary. Much more work is still needed before we fully understand the wide spectrum of clinical signs and symptoms of HFRS as well as the pathogenicity of the different viruses in the hantavirus genus of the Bunyaviridae family. HFRS is difficult to diagnose on clinical grounds alone and serological evidence is often needed. A fourfold rise in IgG antibody titer in a 1-week interval, and the presence of the IgM type of antibodies against hantaviruses are good evidence for an acute hantavirus infection. Physicians should be alert for HFRS each time they deal with patients with acute febrile flu-like illness, renal failure of unknown origin and sometimes hepatic dysfunction. Especially the mild form of HFRS is difficult to diagnose. Acute onset, headache, fever, increased serum creatinine, proteinuria and polyuria are signs and symptoms compatible with a mild form of HFRS. Differential diagnosis should be considered for the following diseases in the endemic areas of HFRS: acute renal failure, hemorrhagic scarlet fever, acute abdomen, leptospirosis, scrub typhus, murine typhus, spotted fevers, non-A, non-B hepatitis, Colorado tick fever, septicemia, dengue, heartstroke and DIC. Treatment of HFRS is mainly supportive. Recently, however, treatment of HFRS patients with ribavirin in China and Korea, within 7 days after onset of fever, resulted in a reduced mortality as well as shortened course of illness.

Monoclonal antibody 791T/36, recognizing a Mr 72,000 antigen on the surface of colon carcinoma cells, has been used to construct an immunotoxin by conjugating to it the ribosomal inhibitor protein, ricin toxin A chain. The antibody 791T/36 has been shown to bind to membranes of freshly disaggregated tumor cells from human colon tumors, and to localize in tumors in vivo. Subacute toxicology testing in rats receiving immunotoxin i.v. showed, at highest doses, weight loss, decreased serum albumin, and hepatocyte vacuolization without elevation in liver function tests. A Phase I dose escalation study was carried out in which 17 patients with metastatic colorectal cancer were treated with doses of immunotoxin ranging from 0.02 to 0.2 mg/kg/day in 1-h i.v. infusions for a 5-day course. Side-effects included a composite of signs and symptoms thought to be generic to ricin A chain immunotoxins, including decreased serum albumin, mild fever, and flu-like symptoms, all being reversible. Two additional findings, reversible proteinuria and mental status changes, were also noted which may be characteristic of this immunotoxin. By 10-20 days after therapy, most patients developed IgM and IgG antibodies against both the ricin toxin A chain and the immunoglobulin portion of the immunotoxin, which were asymptomatic. A strong anticombining site antibody response was seen. Biological activity manifest as mixed tumor regression was seen in five patients.

Intermittent rifampicin therapy has been reported to commonly cause a flu-like illness with chills and fever sometimes associated with acute renal failure. This report describes a fourth case of partially reversible insidious renal damage associated with continuous rifampicin therapy and provides evidence that it is not the results of light chain proteinuria as previously suggested. A retrospective review of data relating to renal function in 89 tuberculous patients indicated that increased plasma urate concentration was commonly associated with ethambutol therapy.

We describe a patient with recurrent thrombotic thrombocytopenic purpura (TTP) manifested solely by aphasia after influenza infection. The clinical diagnosis was not made during acute episodes, and during the intercurrent period the patient had features of chronic glomerular disease, including hypertension, proteinuria, RBC casts, and a nonspecific renal histological appearance. A final episode of aphasia, acute renal failure, and microangiopathic anemia and thrombocytopenia made the diagnosis of TTP apparent. Chronic glomerular disease may in rare instances be a manifestation of occult TTP or the sequel of a prior acute episode of this disorder.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis has been recently recognized in Graves' disease patients treated with propylthiouracil. We have experienced three adult cases of Graves' disease with main features being renal derangements. All three patients, who were between the ages of 22 and 82 years, had been treated with propylthiouracil for 2 to 5 years after a diagnosis of Graves' disease. After several weeks of upper respiratory tract infection or flu-like symptoms, they abruptly began to manifest proteinuria and hematuria concomitant with severe anemia. Their serum creatinine increased from normal levels to 1.2 to 3.6 mg/dL. Renal biopsy revealed crescentic glomerulonephritis without deposition of immune complexes (ie, pauci-immune type). Crescent formations were observed in 40% to 60% of the glomeruli in all three cases. The serum from the patients revealed positive perinuclear-ANCA and negative cytoplasmic-ANCA (C-ANCA) pattern, and myeloperoxidase (MPO)-ANCA titers were 120 to 502 ELISA Units/mL (normal, < 10 ELISA Units/mL). A withdrawal of propylthiouracil with or without immunosuppressive therapy ameliorated their renal derangements. Graves' disease patients should be placed under vigilant observation by monitoring their urinalysis and serum creatinine, especially when being treated with antithyroid drugs and when suffering from flu-like symptoms.

Since their initial description in 1957, the interferons (IFNs) have been increasingly used to treat a wide array of diseases. Acute adverse effects, i.e. 'flu-like' syndromes, hypo- or hypertension, tachycardia, headache, myalgias and gastrointestinal disorders, occur within the first hour or day after starting treatment. They are seldom treatment-limiting and are easily manageable. Sub-acute and chronic effects develop after several days, usually within 2 and 4 weeks of therapy. The most typical is neurological toxicity, including fatigue/asthenia, and behavioural and cognitive changes. Such symptoms may seriously impair quality of life and result in treatment discontinuation. Seizures have seldom been described. Other infrequent central nervous system adverse effects include vertigo, cramp and oculomotor nerve paralysis. Distal paraesthesias and peripheral neuropathy have been reported. IFN-associated autoimmunity is quite rare but a matter of concern. Biological or clinical manifestations usually require several months to become apparent. Autoantibodies have been shown to develop in most patients but have been inconsistently associated with clinical symptoms of systemic lupus erythematosus, rheumatoid-like arthritis and thyroiditis. Both hypo- and hyperthyroidism have been described but are usually reversible. Other infrequent autoimmune reactions include diabetes, pemphigus and worsening of multiple sclerosis. Although several patients present with a pre-existing autoimmune disorder, no predisposing factor has been clearly established. While hypotension and tachycardia are the most frequent acute cardiovascular complications, a few additional cases of cardiac arrhythmias and myocardial ischaemia have been reported after a short course or several weeks of treatment. These latter complications do not appear to be dose-dependent or age-related. Isolated cases of congestive heart failure have also been described. Mild proteinuria has been observed in 15 to 25% of patients, but acute renal toxicity is uncommon. A transient rise in serum aminotransferase levels is frequently noted during the first stage of therapy, especially in patients receiving the highest dosages. Direct hepatotoxicity is extremely rare. Autoimmune hepatitis, which is ill-diagnosed as chronic viral hepatitis, and de novo induction of autoimmune hepatitis, account for the majority of liver diseases. Haematotoxicity is relatively common but mild to moderate, and develops gradually during the first weeks of treatment. Neutropenia is the most common haematological toxicity, but is usually not dose-limiting and resolves rapidly upon drug discontinuation. Myelosuppression, autoimmune and immune allergic haemolytic anaemias and thrombocytopenias have seldom been described. Cutaneous adverse effects comprised nonspecific erythema and hair loss and, less frequently, vasculitis, local ulcerations at the site of injection and exacerbation of psoriasis.(ABSTRACT TRUNCATED AT 250 WORDS)

Puromycin aminonucleoside nephrosis (PAN), a rat model of human minimal change nephropathy, is characterized by extensive flattening of glomerular epithelial cell (podocyte) foot processes and by severe proteinuria. For comparison of expression of glomerular membrane proteins of normal and PAN rats, a membrane protein fraction of isolated rat glomeruli was prepared and monoclonal antibodies were raised against it. An IgG-secreting clone designated LF3 was selected that specifically immunolabeled podocytes of normal but not of PAN rats. The antigen of LF3 IgG was identified as a 43-kd glycoprotein. Molecular cloning of its cDNA was performed in a delta gt11 expression library prepared from mRNA of isolated rat glomeruli. The predicted amino acid sequence indicated a 166-amino-acid integral membrane protein with a single membrane-spanning domain, two potential phosphorylation sites in its short cytoplasmic tail, and six potential O-glycosylation sites in the large ectodomain. High amino acid sequence identities were found to membrane glycoproteins of rat lung and bone and mouse thymus epithelial cells as well as to a phorbol-ester-induced protein in a mouse osteoblast cell line and to a canine influenza C virus receptor. In PAN, expression of this 43-kd protein was selectively reduced to < 30%, as determined by quantitative immunogold electron microscopy, immunoblotting, and Northern blotting. These data provide evidence that transcription of the 43-kd transmembrane podocyte glycoprotein is specifically down-regulated in PAN. To indicate that this protein could be associated with transformation of arborized foot processes to flat feet (Latin, pes planus) we have called it podoplanin.

Like bacterial diseases viral diseases may also be accompanied by functional renal disorders or abnormalities of the urinary sediment. Thus, to find a hematuria or an isolated proteinuria in the context of influenza or hepatitis is not rare at all. In certain cases viral affections may even be accompanied by a nephrotic syndrome. This article aims at the discussion of multiple renal disorders appearing in the context of hepatitis B and C and AIDS.
