The Acquired Immunodeficiency Syndrome (AIDS) has involved the pediatric age group and is especially prevalent in babies born of mothers who are intravenous drug abusers or prostitutes. Approximately 30% of children born to mothers who are seropositive for the human immunodeficiency virus (HIV) will develop HIV infection. There are several important differences in children and adults with AIDS. The incubation period of the disease is shorter, and initial clinical manifestations occur earlier in children. In addition, certain infections are more common in children, and the different types of malignancy, especially Kaposi's sarcoma, are unusual in the pediatric age group. The altered immune system involves both T cells and humoral immunity and increases susceptibility to a variety of infections, particularly opportunistic organisms. In this publication the complications of pediatric AIDS involving the lungs, cardiovascular system, gastrointestinal tract, genitourinary system, and neurological system are described. The most common pulmonary complications in our experience are Pneumocystis carinii pneumonia and pulmonary lymphoid hyperplasia. The spectrum of cardiovascular involvement in pediatric AIDS includes myocarditis, pericarditis, and infectious endocarditis. Gastrointestinal tract involvement is usually due to opportunistic organisms that produce esophagitis, gastritis, and colitis. Abdominal lymphadenopathy is a common finding either due to disseminating Mycobacterium avium-intracellulare infection or nonspecific lymphadenopathy. Although cholangitis is more commonly seen in adults, it may occur in children with AIDS and, in most cases, is due to related opportunistic infections. Genitourinary infections may be the first evidence of HIV disease. Cystitis, pyelonephritis, renal abscesses, and nephropathy with renal insufficiency are complications of pediatric AIDS. A variety of neurological abnormalities may occur in pediatric AIDS. The most common cause of neurological dysfunction in children with AIDS is HIV neuropathy. We present the many complications of AIDS in children demonstrated by a variety of imaging modalities, emphasizing the importance of diagnostic imaging in children with this disease.

Trimethoprim-sulfamethoxazole continues to be a useful antibiotic for common outpatient problems such as urinary tract infections, prostatitis, acute exacerbations of chronic bronchitis, and acute otitis media as well as for serious infections of the hospitalized patient including Pneumocystis carinii pneumonia, acute pyelonephritis, and some forms of gram negative meningitis. The other sulfonamides have a limited role.

Necropsies were performed in 12 patients who fulfilled the Centers for Disease Control (CDC) criteria for acquired immunodeficiency syndrome (AIDS), and the postmortem findings were compared with the premortem diagnoses. All of the patients were men with a male sexual preference and histories of multiple episodes of venereal diseases. Four patients were intravenous drug abusers, while two abused amyl nitrate. All 12 of the patients had evidence of cellular immune deficiency at presentation. The causes of death were a variety of opportunistic infections and neoplasms. Pneumocystis carinii pneumonia was diagnosed prior to death in seven patients. Despite current therapy, all seven of those patients had persistent Pneumocystis carinii pneumonia at necropsy, as well as clinically undiagnosed cytomegalovirus infection. In addition, two cases of acid-fast infections, two of visceral candidiasis, one of pneumocystis pneumonia, one of central nervous system lymphoma, one of gram-negative bacterial pyelonephritis, and one of cutaneous aspergillosis were clinically unrecognized and untreated. Nine patients died with two or more infections. Thus, necropsy is a valuable tool for recognizing clinically undiagnosed infections and malignant disorders in AIDS.

Biogenesis of tetrahydrofolate cofactors essential for bacterial growth and survival is blocked by sulfamethoxazole-trimethoprim. An intravenous form of the antimicrobial combination has recently been approved for the treatment of acute, symptomatic, bacterial pyelonephritis, recurrent urinary tract infections, shigellosis, and Pneumocystis carinii pneumonia. Intravenous sulfamethoxazole-trimethoprim has emerged as an invaluable agent for the management of selected infections, including bacterial meningitis and Salmonella bacteremia, where limited therapeutic alternatives exist. In addition, co-administration of intravenous sulfamethoxazole-trimethoprim with a carboxypenicillin provides an empiric treatment for the infected granulocytopenic patient that compares favorably with standard combinations. Adverse events unique to the intravenous form of the drug consist of phlebitis and fluid imbalances. Fluid overload results from the relatively large volumes of 5% dextrose solution required as diluent.

Infectious complications are one of the leading causes of hospitalization and mortality in kidney transplant recipients. They are more frequent during the year following transplantation, and in the elderly. Community infections, such as pyelonephritis and pneumonia, are from far the most common infections. However, the field of opportunistic infections has been particularly moving as routine prophylaxis for cytomegalovirus and pneumocystosis have altered their patterns. Emergence of new infections, as BK nephritis, followed by chronic infections by Norovirus and E hepatitis, and increasing incidence of invasive fungal infections and mycobacterial infections have raised concerns. An increasing number of infections may be prevented by prophylaxis, but also by vaccines who should be encouraged, especially for influenza, pneumococcal diseases and zoster. Access to transplantation is now possible for human immunodeficiency virus infected patients, with good results. The field of infectious diseases is thus changing in kidney transplant recipients, due to high-risk recipients, new immunosuppressive drugs, and development of new diagnostic, therapeutic and preventive methods.
