Renal aspects of therapy for human immunodeficiency virus and associated opportunistic infections.

Patients with human immunodeficiency virus infection and the acquired immunodeficiency syndrome are often treated with a variety of potentially nephrotoxic drugs. This review summarizes the renal, fluid, and electrolyte complications of drugs used to treat human immunodeficiency virus and associated opportunistic infections. The pharmacokinetics of the drugs are also briefly reviewed, and dosing guidelines for the use of these drugs in patients who have renal insufficiency or who are receiving dialysis are provided.

Normal splenic function in children with the nephrotic syndrome.

Children with the idiopathic nephrotic syndrome (NS) are known to be susceptible to bacterial infections. A recent report suggested that splenic hypofunction may be responsible for this immunological defect. We assessed splenic function by counting the circulating pocked red blood cells (PkRBCs) using interference phase contrast microscopy. PkRBCs are removed by the spleen, so that normal eusplenic individuals have less than 2% PkRBCs while asplenics have 15%-30%. Intermediate values are seen in hyposplenism. Thirty-three measurements of PkRBCs were made in 19 children with NS (mean age 7.5 +/- 0.8 years). PkRBCs were normal in all children tested (range 0-0.8%), including two patients with bacterial peritonitis associated with relapse. Thus we were unable to find evidence of hyposplenism in children with NS.

Steroid-responsive nephrotic syndrome of childhood: a long-term study of clinical course, histopathology, efficacy of cyclophosphamide therapy, and effects on growth.

The long-term clinical course of 60 children with steroid-responsive nephrotic syndrome, observed for a minimum of 10 years from onset, was studied (mean 14.5 +/- 0.5 years). Four children had only a single episode, seven children experienced only one to three relapses early in their course, and the remaining 49 patients (82%) experienced frequently relapsing steroid-dependent disease. Nearly half of these (47%) continued to relapse into their late teens and early twenties. All 20 children treated with cyclophosphamide because of steroid-induced side effects developed complete remissions of the nephrotic syndrome. These were sustained in 70% for 9.1 +/- 0.6 years, with a reduction of disease severity in the remaining 30%. In contrast, only 48% of patients treated with prednisone alone were in remission at last follow-up (P = .06). Ten of the children treated with cyclophosphamide had the minimal change lesion prior to therapy; 90% of these had permanent remissions. Only 50% of the six children with focal glomerulosclerosis and four children with mesangial proliferation have had permanent remissions. None of the patients developed renal insufficiency. Children treated with prednisone alone were -0.93 +/- 0.3 SD below the mean for height at last follow-up. Cyclophosphamide treatment was associated with an increase in height SD scores from -0.84 +/- 0.4 to -0.28 +/- 0.3. Children with severe growth impairment demonstrated dramatic catch-up growth when treated with cyclophosphamide with SD scores increasing from -2.29 +/- 0.8 to -0.43 +/- 0.6 (P less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)

Progression of orthostatic proteinuria to focal and segmental glomerulosclerosis.

Focal glomerulosclerosis, with the nephrotic syndrome and progressive renal insufficiency, developed in a 15-year-old boy who presented initially 1 year earlier with orthostatic proteinuria. Although generally considered to be a benign disorder, this case suggests that on rare occasions, serious glomerular diseases may develop in patients with orthostatic proteinuria or that significant glomerular disease may occasionally present with postural proteinuria.

Studies of a family with incontinentia pigmenti variably expressed in both sexes.

A family is described in which incontinentia pigmenti (IP) is variably expressed in both sexes, compatible with either autosomal dominant or X linked dominant inheritance. This is the first reported instance of an affected male with a positive family history. Immunological studies of the proband showed no significant alteration of immune function. Cytogenetic investigations of the proband and her affected brother and mother revealed no unusual propensity for chromosome breaks or gaps and no enhancement of sister chromatid exchanges.

Duplication 6q syndrome.

Duplication (partial trisomy) of the long arm of chromosome 6 has been described in 5 children [Robertson et al, 1975, Chen et al, 1976, Clark, 1977]. We wish to report here an additional case due to a familial translocation in which the proband's karyotype is 46,XX,der(3),rcp(3;6)(p25;q21)mat. The phenotypes of the 6 children with duplication 6q are strikingly similar. Each child has duplication involving approximately the distal 1/3 to 1/2 of the long arm of chromosome 6. Distinctive features present in all 6 children include microcephaly, acrocephaly, prominent forehead, flat facial profile, depressed nasal bridge, flat malar areas, "carp" mouth, micrognathia and mental retardation. The phenotype of the duplication 6q syndrome is distinctive enough to be clinically recognizable.

Nonsurgical cure of pulmonary mucormycosis.

Pulmonary mucormycosis is an unusual infection which appears to occur with increased frequency in diabetics. We report the development of pulmonary mucormycosis in an adult onset diabetic which resolved with medical therapy alone. Computerized tomography proved useful in assessing his response to therapy.
