We have followed 46 children with acquired immunodeficiency syndrome and acquired immunodeficiency syndrome-related complex. Twenty-six patients had at least one episode of serious bacterial infection. Twenty-seven episodes of sepsis were documented in 21 patients. Soft tissue infection was common in both the presence and the absence of documented bacteremia. Urinary tract infection commonly presented as worsening diarrhea in the absence of sepsis. Organisms commonly isolated included Streptococcus pneumoniae, Haemophilus influenzae and Salmonella sp. Staphylococcal infection accompanied episodes of cellulitis/abscess. Escherichia coli commonly caused urinary tract infection in the absence of sepsis. Enteric and nosocomial sepsis was limited to hospitalized, instrumented patients or to individuals who had received prior antibiotic therapy as outpatients. We conclude that bacterial infection causes serious morbidity in acquired immunodeficiency syndrome and acquired immunodeficiency syndrome-related complex and may be further evidence for altered humoral immunity in the disorder.

The isolation frequency of pathogenic bacteria for acute respiratory infection (ARI) in the pharynx and nasal vestivulum was investigated. Age group-matched children with or without ARI including 109 individuals in each group were examined. Any of the organisms, which are widely regarded as the pathogens causing ARI such as Haemophilus influenzae, Streptococcus pneumoniae, beta-haemolytic Streptococcus, Staphylococcus aureus, and Moraxella catarrhalis, were isolated from 91% of the patient group and from 77% of the healthy group. The isolation frequency of S. pneumoniae in the nasal vestivulum of the patient group was outstanding. The healthy carrier rates of S. pneumoniae in the pharynx and nasal vestivulum were 9% and 8%, respectively. Whereas the isolation frequencies from the patient group were 7% and 28%, respectively. alpha-haemolytic Streptococci except S. pneumoniae revealed different tendency from S. pneumoniae. These organisms were almost always isolated from their pharynx but rarely isolated from the nasal vestivulum. The isolation frequency of H. influenzae from the pharynx of the patient group was 41%, which was slightly higher than 34% in the healthy group, but the difference was statistically not significant. H. influenzae was not isolated from the nasal vestivulum of the healthy group, nevertheless it was isolated from 25% of the patient group. The isolation of H. influenzae from the nasal vestivulum may have some important information about ARI. S. aureus was isolated from the pharynx with higher rate than the nasal vestivulum in both groups, and moreover, the isolation frequency of S. aureus in the healthy group was higher than the patient group. It means that the diagnosis of staphylococcal infection should be made very carefully. Considering the results of this study, it could be said that bacteriologic examination of the specimens from nasal vestivulum is valuable to determine S. pneumoniae and H. influenzae as the etiologic agents of ARI.

Diagnosis of erysipelas is based upon the association of an acute inflammatory plaque with fever, lymphagiitis, adenopathy and hyperleukocytosis. These associated symptoms are variable (20-70 p. 100 of cases). Bacteriology is not helpful for the diagnosis of erysipelas because of a low sensitivity (hemoculture 5 p. 100, standard examinations 5-41 p. 100), or delayed positivity (serology). Moreover cutaneous bacteriology is difficult to assess when other bacteria than streptococci are isolated. Erysipelas have to be distinguished from non-necrotizing cellulitis by peculiar clinical features (such as erysipeloid, facial staphylococcal infection, Pasteurella, Haemophilus influenzae) and from necrotizing fasciitis. Some non-infectious diseases may mimic erysipelas such as venous thrombosis, familial Mediterranean fever, prosthesis intolerance, and compartment syndrome. Because the diagnostic value of clinical symptoms is not known and no diagnostic gold standard has been established, it is impossible to be sure that non-streptococcal erysipelas (especially staphylococcal) really exists. Thus, the first line treatment for all erysipelas must be an antistreptococcal antibiotic. Before prescribing a treatment, hemoculture and blood cell count could be useful. If antistreptococcal antibiotherapy is inefficient, all the differential diagnoses must be reviewed.

Trimethoprim-sulfamethoxazole (TMP-SMZ) is widely prescribed as prophylaxis for Pneumocystis carinii pneumonia (PCP) in human immunodeficiency virus (HIV)-infected persons. Its efficacy against other infections has not been thoroughly evaluated. To compare the risk for infectious diseases for persons who were prescribed TMP-SMZ with that for patients who were not prescribed TMP-SMZ, we examined data collected from the medical records of HIV-infected patients (January 1990 through September 1999) who were enrolled in the Adult and Adolescent Spectrum of HIV Disease Project. During intervals when patients had CD4(+) T lymphocyte counts of <200 cells/microL (19,081 persons; 22,801 person-years), prescription of TMP-SMZ was associated with significant protection from toxoplasmosis, salmonellosis, infection with Haemophilus species, invasive or any staphylococcal infection, and PCP, but not from Shigella, pneumococcal or nonpneumococcal Streptococcus, Klebsiella, or Pseudomonas species. We demonstrate that prescription of TMP-SMZ for PCP prophylaxis in persons with HIV infection is associated with significantly decreased risk for several infectious diseases. These findings may be of interest to HIV prevention programs in resource-poor countries.
