Several renal and renal-related disturbances have been described in patients with AIDS (acquired immune deficiency syndrome), in adults and children as well. These are mainly electrolyte and acid-base imbalance, acute renal failure and nephrotic syndrome. The latter is usually steroid non-responder. The renal histopathological lesions described more commonly are minimal change, mesangial hyperplasia and focal segmental glomerulosclerosis. Herein, we describe a 5 year-old with AIDS, that developed nephrotic syndrome, characterized by edema, ascites, hypoalbuminemia and massive proteinuria. A percutaneous renal biopsy showed mesangial proliferation. She did not respond to a 6 week treatment with prednisone. She died with sepsis after several viral and bacterial infections.

A 19-month-old boy with AIDS developed clinically unexplainable proteinuria. Biopsied renal tissue was examined by light microscopy, transmission electron microscopy, and immunofluorescence. Findings included an increase of mesangial matrix with occasional nodular sclerosis, mesangial hypercellularity, and glomerular deposits of kappa and lambda light chains. There were deposits of kappa, but not lambda, light chains in the arteriolar walls, and around the tubular and interstitial capillary basement membranes. Quantitative urinary immunoelectrophoresis revealed an extremely high urinary concentration of kappa light chain. These changes are diagnostic of light chain nephropathy. The rarity of light chain nephropathy in childhood and its occurrence in a patient with AIDS make this case unusual.

This essay illustrates the spectrum of sonographic findings of various renal manifestations of AIDS. The most common renal abnormality in patients with AIDS is nephropathy, which is manifested by deterioration of renal function and proteinuria. Acute tubular necrosis, intrarenal infections, focal nephrocalcinosis, hydronephrosis, and neoplasms also may occur.

Nephropathies associated with human immunodeficiency syndrome (HIVAN) are characterized by gross proteinuria, lack of change in blood pressure, and various histologic lesions. The present study prospectively measured microalbuminuria in 72 HIV-seropositive patients (3 asymptomatic, 32 AIDS-related complex, 37 AIDS) screened for Phase I clinical pharmacology studies. There were 14 patients (19.4%) that had abnormal urinary levels of microalbumin; 7 of these patients (50%) had proteinuria similar to those values found in diabetic nephrotic syndrome. Microalbumin levels were not correlated with race, sex, risk factors of AIDS, disease history, or concurrent drug therapy. In contrast, urinary microalbumin levels were correlated with CD 4 T-cell and WBC counts, tumor necrosis factor alpha and beta 2-microglobulin levels, suggesting an association between AIDS progression and microalbuminuria. By monitoring urinary microalbumin levels, those patients susceptible to the development of nephrotic syndrome could be identified and prophylactic measures initiated.

One hundred and twenty six patients diagnosed as having AIDS had their urinalysis and electrolyte profiles studied. The commonest electrolyte abnormalities were a low serum bicarbonate in 56% of the patients and hyponatraemia in 48%. Possible aetiological factors are discussed. Significant pyuria was found in 10% of the patients and significant bacteriuria in 13%. Escherichia coli was the commonest isolated organism (56% of all the culture positive cases). Proteinuria above the upper limit of normal was detectable in 13% of the patients; of these, 25% had proteinuria in the nephrotic range. Of the patients 3% had clinical and biochemical evidence of renal insufficiency. It is concluded that significant bacteriuria occurs commonly in AIDS and that renal insufficiency and nephrotic syndrome may be associated with the disease. It is also noted that other electrolyte and acid-base abnormalities, in particular hyponatraemia and low bicarbonate levels may contribute to the morbidity and mortality in patients suffering from AIDS.

Infection with the human immunodeficiency virus type 1 (HIV-1) can cause a spectrum of renal disease, termed acquired immunodeficiency syndrome (AIDS) nephropathy. The most common clinical manifestations of kidney involvement in HIV-1-infected patients are proteinuria and/or nephrotic syndrome, and the histopathological pattern usually reveals focal segmental glomerulosclerosis. We describe an 8-year-old child with AIDS who presented with recurrent gross hematuria. A kidney biopsy demonstrated IgA nephropathy. This unique case indicates that the range of kidney disease in HIV-infected children may be broader than originally thought, and that these patients warrant a complete evaluation of any renal abnormality.

We report here the cases of 15 children in whom nephrotic syndrome developed, from among 164 children (55% male, 90% black) followed in our acquired immunodeficiency syndrome clinic from 1984 through 1990. Mean age at onset of nephrotic syndrome was 4.9 +/- 2.6 years. Fourteen patients were black and one was Hispanic. Seventy-three percent of our patients with nephrotic syndrome were girls. The mean duration of clinical acquired immunodeficiency syndrome before development of nephrotic syndrome was 1.7 +/- 1.1 years. In eight patients, nephrotic syndrome appeared between 3 and 11 months after intravenous infusions of immune globulin or albumin were administered as part of a research protocol; this incidence (8/47) was higher than the incidence of nephrotic syndrome among those who did not receive intravenous infusions (7/117, p less than 0.05). Tissue for histologic examination was available for 80% of the patients, and histologic examination demonstrated mesangial hypercellularity (5 patients), focal segmental glomerulosclerosis (4 patients), minimal change disease (2 patients), and IgM nephropathy (1 patient). Deposition of one or more immunoglobulins was noted in all but one patient studied with immunofluorescence. Corresponding electron-dense deposits were seen by electron microscopy in 78% of specimens. Prednisone did not induce a remission of nephrotic syndrome in the 13 patients treated, whereas cyclosporine did so in the 3 patients to whom it was administered. Five patients were in the end stage of renal disease within 8 months. Successful maintenance peritoneal dialysis was performed in three patients, but 80% of patients have died of human immunodeficiency virus-related complications; one patient was lost to follow-up. We conclude that immune-complex deposition is consistently seen in children with human immunodeficiency virus-associated nephrotic syndrome. This nephrotic syndrome is resistant to steroid therapy, but we observed a remission of the proteinuria with cyclosporine therapy in three patients. For patients with end-stage renal disease, maintenance peritoneal dialysis may improve the quality of life.

A survey of consultations to the Division of Nephrology at San Francisco General Hospital from 1982 to 1988 found only seven cases of proven or possible renal disease matching that described for human immunodeficiency virus (HIV)-associated nephropathy (nephrotic proteinuria, rapidly progressive renal insufficiency, and focal and segmental glomerulosclerosis [FSGS] histologically). In the period from April 1, 1988 (the conclusion of the original survey) through December 31, 1990, a roughly 11-fold increase in the incidence of such cases among referrals of HIV-infected patients to the Division occurred compared with the initial experience. The patients were nearly exclusively black men, only about half of whom had intravenous drug abuse (IVDA) as an HIV risk factor. This striking increase was associated with a progressive increase in the number of black patients with acquired immunodeficiency syndrome (AIDS) in San Francisco, and in the percentage of patients with an AIDS diagnosis discharged from San Francisco General Hospital (SFGH) who were black. These data support other evidence indicating a particular vulnerability of blacks to this form of renal disease and help to reconcile data from our division with the experience reported from other centers.

A rapidly enlarging left inguinal adenitis, with positive groove sign, and fever, chills, malaise, hypotension, headache, scarlatiniform rash, choleroid diarrhea, and proteinuria developed in an homosexual man who was positive for human immunodeficiency virus. The needle aspiration of the inguinal mass showed group A beta-hemolytic streptococci and the blood cultures were negative, suggesting group A streptococcal cellulitis-adenitis with toxic strep syndrome. Treatment with penicillin and surgical drainage was successful. Bacterial infections associated with defective humoral immunity appear to be common in patients with acquired immunodeficiency syndrome (AIDS), and some of these infections have a remarkable extensive and lethal evolution. Therefore streptococcal adenitis should be considered in any patient with AIDS or AIDS-related syndrome in whom rapidly enlarging inguinal nodes develop.

We performed a retrospective chart analysis on 449 AIDS patients admitted to Bellevue Hospital Center from 1983-1986 to characterize the etiologies and clinical course of acute renal failure (ARF) and to define the incidence and clinical course of AIDS-associated nephropathy (AAN) in an unselected hospitalized AIDS population. Defining ARF as a rise from baseline serum creatinine of at least 2.0 mg%, we found 88 cases (a prevalence of almost 20%) or 14.5 cases per 100 admissions. Volume depletion was the most common etiology and was as severe a cause of ARF as other etiologies. There were 21 cases of ARF in 17 patients with a peak serum creatinine greater than or equal to 6.0 mg%. Volume depletion accounted for 7/21 of these cases. Baseline renal insufficiency existed in 9/17 patients (12/21 cases) and volume depletion was the cause of ARF in 3 of these cases. Only 4 cases required dialysis. There were 34 patients (prevalence of 7.6% or 3.0 cases per 100 patient-years) with otherwise unexplained chronic renal insufficiency and/or persistent qualitative or quantitative proteinuria and thus were defined on clinical grounds to have AIDS-associated nephropathy. Thirty-two of these patients (94%) had evidence of AAN at or within 1 year of presentation. Eleven patients (32%) reached ESRD (serum creatinine greater than or equal to 6.0 mg%); 9 patients did so within 1 year of presentation and 3 required dialysis. In those with adequate follow-up (9 cases), the mean survival from time of ESRD was 25.5 days and all cases died within 6 months of reaching ESRD.(ABSTRACT TRUNCATED AT 250 WORDS)
