The clinical manifestations of drug-induced renal disease may include all the manifestations attributed to natural or spontaneous renal diseases such as acute renal failure, chronic renal failure, acute nephritic syndrome, renal colic, haematuria, selective tubular defects, obstructive nephropathy, etc. It is therefore vital in any patient with renal disease whatever the clinical manifestations might be, to obtain a meticulous drug and toxin inventory. Withdrawal of the offending drug may result in amelioration or cure of the renal disorder although in the case of severe renal failure it may be necessary to utilise haemodialysis or peritoneal dialysis to tide the patient over the period of acute renal failure. Analgesic nephropathy is an important cause of terminal chronic renal failure and it is therefore vital to make the diagnosis as early as possible. The pathogenesis of some drug-induced renal disorders appears to be immunologically mediated. There are many other pathogenetic mechanisms involved in drug-induced renal disorders and some drugs may under appropriate circumstances be responsible for a variety of different nephrotoxic effects. For example, the sulphonamides have been incriminated in examples of crystalluria, acute interstitial nephritis, acute tubular necrosis, generalised hypersensitivity reactions, polyarteritis nodosa and drug-induced lupus erythematosus.

Patients with lupus nephritis and severe renal failure progress to end-stage renal disease despite aggressive therapy to suppress immunologic function. Within this group is a small subset presenting with rapid progression of renal failure and requiring dialytic support. We reviewed the clinicopathologic data of four such patients who were able to terminate dialysis after acute renal failure due to lupus nephritis. Three of these patients have remained independent of dialysis up to 4 years, and one patient returned to dialysis 1 month following discontinuation. Although glomerular pathology was variable in the four patients, a lesion common to all at presentation was acute tubular necrosis. It is suggested that tubular necrosis may cause reversible renal failure when part of the nephropathy of disseminated lupus treated with corticosteroids.

The survival of patients in end-stage renal failure from lupus nephritis offered renal substitution therapy has been the subject of conflicting reports. Trying to clarify the reasons for this discrepancy, we analysed our experience with dialysis and transplantation in systemic lupus erythematosus (SLE). Of our 138 patients with lupus nephritis, 26 reached end-stage renal failure, of whom 24 received replacement therapy. Fourteen patients had a marked acute deterioration in renal function immediately before reaching terminal uremia, associated with active SLE in 12 and acute tubular necrosis after hypotension in one. Nine patients in this group died, 8 within 1 month of beginning dialysis. Nine patients progressed slowly to endstage renal failure over 2 to 7 years, without evidence of active SLE: only 1 required aggressive treatment and only 3 patients died, 1 five years after transplantation. Eight patients received altogether 10 allografted kidneys; 4 still functioning 10-24 months later; 2 patients are back on dialysis and 2 died, 1 of a myocardial infarct. There was no evidence of active SLE after transplantation. Ten patients were dialysed for more than 3 months; most were maintained on prednisolone and azathioprine whilst on dialysis and lupus activity tended to abate. The exclusion of the group of patients with rapid pre-terminal decrease in renal function from some series may explain some of the differences in reported survival. Stable patients with SLE present few problems in end-stage renal failure or after transplantation.

The early use of gold in medicine and dentistry dates back to the ancient Chinese and Egyptians. The discovery in 1890 that gold salts were toxic in vitro to tubercle bacilli led to the extensive treatment of tuberculosis with gold salts in the first three decades of this century. Eventually, gold therapy was extended to arthritis and lupus erythematosus, because of the belief that these diseases were forms of tuberculosis. Because of its beneficial effect particularly on active rheumatoid arthritis, chrysotherapy has remained one of the most widely used treatments of rheumatoid arthritis for the past half century. Toxicity of gold salts includes hypersensitivity reaction of skin and mucous membranes, bone marrow depression, and nephrotoxicity. The nephrotoxic clinical manifestations are renal insufficiency, proteinuria and hematuria, and the nephrotic syndrome. The pathologic changes are tubular degeneration, acute tubular necrosis or immune complex glomerulonephritis. The justification that any of these possible changes are the result of gold therapy rests clinically upon the time relationship of gold therapy and the renal symptoms, and pathologically upon the presence of gold inclusions (aurosomes) in proximal tubular epithelial cells. Aurosomes can at times be visualized by light microscopy, are usually seen by electron microscopy, and can be identified by microprobe analysis. Their pathology will be illustrated and pathogenic mechanisms discussed.

2 patients with systemic lupus erythematosus and mild renal functional impairment were treated with ibuprofen, one of the phenylproprionic nonsteroidal anti-inflammatory drugs. Within days after the onset of therapy, both developed renal insufficiency manifested by elevated serum creatinine levels, increased proteinuria, and active urinary sediments; 1 patient was oliguric. Renal biopsies disclosed mesangial proliferative lupus glomerulonephritis and acute tubular necrosis, the latter more pronounced in the oliguric patient. Renal failure resolved following discontinuation of ibuprofen and supportive therapy. It is postulated that altered blood flow, mediated through the well-known prostaglandin synthetase inhibitory effects of ibuprofen, resulted in tubular necrosis. This undesirable complication of ibuprofen therapy may be enhanced in patients with underlying renal disease, and may be a factor governing the limitation of its usage.

Protease nexin 1 (PN-1), a potent serpin-class antiprotease, is thought to be synthesized in the murine kidney. However, neither the cellular localization of PN-1 synthesis nor its role has yet been defined. To address these questions, we determined by in situ hybridizations RNase protection assay and immunoblotting, the sites of PN-1 mRNA accumulation in normal mouse kidneys and the modulation of PN-1 expression in several pathological conditions. In normal kidneys, PN-1 mRNA was detected primarily in glomeruli, most likely in mesangial cells. The glomerular expression of PN-1 was substantially enhanced not only in lupus-like glomerulonephritis (induced by IgG3 monoclonal rheumatoid factors or occurring spontaneously in lupus-prone mice), but also in mild glomerular lesions associated with intracapillary thrombi induced by IgG3 anti-trinitrophenyl monoclonal antibodies. In contrast, no modulation of PN-1 mRNA levels was observed during the course of lipopolysaccharide-induced acute tubular necrosis. A constitutive PN-1 gene expression and its up-regulation during glomerular injury suggest a possible role for PN-1 in glomerular biology. In view of its high inhibitory activity towards thrombin, mesangial PN-1 may be involved in the control of glomerular coagulation following initial glomerular injuries.

We describe here the broad spectrum of acute renal insufficiency occurring in the course of human immunoinsufficiency virus infection. In our renal unit in Tenon hospital, 90 human immunoinsufficiency virus-infected adult patients were admitted for acute renal insufficiency between June 1988 and December 1996. Sixty out of them had a pathological diagnosis. The remaining patients did not have renal biopsy because of obstructive renal failure (n = 2), bleeding risk (n = 11), or clinically evident hypovolemic and/or sepsis-related acute tubular necrosis (n = 17). Nine different causes of acute renal insufficiency were listed. Human immunoinsufficiency virus-associated nephropathy, the most specific human immunoinsufficiency virus-related renal disease, which was diagnosed in 14 patients, is characterized by focal and segmental glomerulosclerosis with an important hyperplasia and/or proliferation of podocytes and huge tubular distension. The rapid progression to end-stage renal failure was not a constant feature since 10/14 patients had a partial renal recovery. Hemolytic-uremic syndrome was the other major cause of acute renal failure in these patients (32 cases) and was found to be associated with active cytomegalovirus infection. Cytomegalovirus-infected cells were present in half of the renal biopsies performed in this group of patients. Furthermore, these patients had an increased plasma tissue-type plasminogen activator activity whereas its type 1 inhibitor was not significantly increased, as opposed to non human immunoinsufficiency virus-associated hemolytic-uremic syndrome. Half of the patients had a complete renal recovery. The other causes of acute renal insufficiency were 1) intratubular deposition of either drugs (Adiazine, Foscavir, Indinavir) in 13 patients, or monoclonal light chain in one patient with B cell-lymphoma; 2) lupus-like glomerulonephritis characterized in one case by a complete clinical remission after 6 month-treatment by antiproteases; 3) acute tubular necrosis. In this setting, rhabdomyolysis could reveal HIV infection. The heterogeneity of renal diseases could be explained by the variation of human immunoinsufficiency virus-associated infections along time and by the different drugs which permit a better survival. We can hypothesize that new HIV-associated diseases will occur with the long term use of antiproteases.

Renal complications of HIV infection are clinically and morphologically diverse. These may affect the glomerular, tubulointerstitial, and vascular compartments. Tubulointerstitial injury predominates in most autopsy-based studies, whereas glomerular disease is most frequently identified in biopsy-based studies. The most common glomerular lesion is HIV-associated focal segmental glomerulosclerosis and related mesangiopathies (collectively termed HIV-associated nephropathy). Increasingly, a variety of immune complex-mediated glomerular diseases such as membranoproliferative glomerulonephritis, IgA nephropathy and lupus-like nephritis, as well as hemolytic uremic syndrome/thrombotic thrombocytopenic purpura have been reported. The spectrum of tubulointerstitial lesions includes acute tubular necrosis, interstitial nephritis, diffuse infiltrative lymphocytosis syndrome, renal infection, and neoplasms including lymphoma and Kaposi's sarcoma. The pathological features of these conditions are reviewed with emphasis on clinical-pathological correlations and pathogenesis.

Although renal disease in pregnancy is uncommon, it poses considerable risk to maternal and fetal health. This article discusses renal physiology and assessment of renal function in pregnancy and the effect of pregnancy on renal disease in patients with diabetes, lupus, chronic glomerulonephritis, polycystic kidney disease, and chronic pyelonephritis. Renal diseases occasionally present for the first time in pregnancy, and diagnoses of glomerulonephritis, acute tubular necrosis, hemolytic uremic syndrome, and acute fatty liver of pregnancy are described. Finally, therapy of end-stage renal disease in pregnancy, dialysis, and renal transplantation are reviewed.
