The present study was undertaken to determine if measurement and analysis of phagocyte function are useful for diagnosis and staging of infection. Circulating phagocyte activity was measured in healthy volunteers and sequentially in patients with acute infections of different types and severity, including those with diabetes mellitus or human immunodeficiency virus (HIV) infection. Using an automated luminescence system, these phagocyte functions were measured in whole blood: basal and phorbol 12-myristate 13-acetate (PMA)-stimulated oxidase activity, basal and PMA-stimulated simple dioxygenation (e.g., oxidase-driven haloperoxidase activity), and circulating and primed opsonin receptor-dependent dioxygenation. Multiple discriminant analysis of these data showed significant differences between healthy controls, diabetic patients, HIV-positive subjects, and patients with pneumonia or sepsis syndromes. Longitudinally, circulating phagocyte function correlated with clinical condition, severity of infection, and outcome. This methodology provides rapid, objective, and sensitive diagnostic and monitoring information for patients with infections.

One hundred twenty three microaerophilic streptococci (MS) were isolated from 4,603 specimens submitted for the identification of anaerobic bacteria over the course of 12 years. The MS included 16 Streptococcus constellatus, 43 Streptococcus intermedius and 21 Gemella morbillorum. A total of 81 MS isolates (66%) identified from 75 patients were considered to cause infection. Predisposing or underlying conditions were noted in 48 (64%) patients. The most common conditions were previous surgery (15 instances), trauma (10), diabetes (9), immunodeficiency (6), malignancy, and prosthetic device (5 each). MS were the only bacterial isolates in 23 instances. Mixed infection was encountered in 52 (69%) patients, where the number of isolates varied between two and five (average 2.7). The organisms most commonly isolated with MS were anaerobic cocci, Bacteroides sp. and Enterobacteriaceae; their recovery varied at different sites. Significant infections caused by MS were associated with abscess (29 instances), sinuses (7), obstetrical and gynecological (OBG), chest and wounds (6 each), abdominal (5), and biliary infection (4). Antimicrobial therapy as administered to 71 patients; for 43 patients, in conjunction with surgical drainage or correction. Surgical drainage alone was performed in three patients. Four patients (5%) died. These data illustrate that MS can occasionally be associated with serious infection.

Fourteen patients with 15 open tibial fractures were examined retrospectively to compare postoperative infection rates of asymptomatic patients who tested positive or negative for the human immunodeficiency virus antibody (HIVab). All patients were treated with a standard open-fracture protocol. All of the HIVab-positive patients developed postoperative infections. There were five postoperative infections in 4 patients; 3 of the 4 patients were HIVab-positive and 2 of these patients developed chronic osteomyelitis. The only other infection, in an HIVab-negative patient with insulin-dependent diabetes, resolved without complication. All other HIVab-negative patients had no complications. The infection rate for asymptomatic HIVab-positive patients with open tibial fractures was higher than that for HIVab-negative patients in our study. These data suggest that the HIV status of patients with open tibial fractures is relevant to treatment outcome.

A total of 243 strains of Fusobacteria species was recovered from 226 of 1399 (16%) specimens obtained from 213 children. The strains included 65 (27%) Fusobacterium sp., 144 (59%) Fusobacterium nucleatum, 25 (10%) Fusobacterium necrophorum, five (2%) Fusobacterium varium, three (1%) Fusobacterium mortiferum, and one (0.4%) Fusobacterium gonidiaformans. Most Fusobacteria species were recovered from patients with abscesses (100), aspiration pneumonia (24), paronychia (15), bites (14), chronic sinusitis (ten), chronic otitis media (nine), and osteomyelitis (eight). Predisposing conditions were noted in 32 (15%) of the cases. These included immunodeficiency in nine (4%), steroid therapy in eight (4%), previous surgery in six (3%), diabetes in six (3%) and malignant neoplasms in five (2%). Fusobacteria sp. was the only isolate in 16 (8%) instances while mixed infections were encountered in 197 (92%) patients. The organisms most commonly isolated with Fusobacteria sp. were anaerobic cocci (155), pigmented Prevotella sp. and Porphyromonas sp. (95), Bacteroides fragilis group (80), Escherichia coli (43) and Bacteroides sp. (39). Most strains of B. fragilis group and E. coli were recovered from intra-abdominal infections and skin and soft tissue infections proximal to the rectal area. Most pigmented Prevotella sp. and Porphyromonas sp. were recovered from oropharyngeal and pulmonary sites and from sites around the head and neck. Antimicrobial therapy was administered to all patients; surgical drainage was performed in 85 (40%). All patients, except two who died, recovered. These findings illustrate the prevalence of Fusobacteria sp. associated with infections in children.

A total of 148 isolates of microaerophilic streptococci (MS) (47 Streptococcus constellatus, 43 Streptococcus intermedius and five Gemella morbillorum) were cultured from 123 children. There were predisposing conditions in 47 (38%) patients of which most common were previous surgery (14), trauma (11), malignancy (9) diabetes (6) and immunodeficiency (5). MS were the only bacteria isolated from 12 (10%) patients and mixed infections were encountered in 111, when the number of isolates varied between two and seven (average 3.0) isolates per specimen. The bacteria most commonly isolated with MS were anaerobic cocci (70 isolates), Bacteroides fragilis group (54), pigmented Prevotella and Porphyromonas (34) and Escherichia coli (26). Most B. fragilis and E. coli were recovered from intra-abdominal infections, and those of skin and soft tissue adjacent to the rectum. Most pigmented Prevotella and Fusobacteria were isolated from oropharyngeal, pulmonary, head and neck sites. Most MS were recovered from abscesses (43%), the abdominal cavity (17%), sinuses (10%) and chest infections (9%). Antimicrobial therapy was administered to all patients, in 61 this was combined with surgical drainage or correction. Three patients died. These data illustrate that MS can occasionally be associated with infection in children.

A 78-year-old man, who suffered from chronic lymphocytic leukaemia and diabetes mellitus, but was human immunodeficiency virus (HIV)-negative, developed disseminated angiomatous papules following a cat scratch. Bacillary angiomatosis was diagnosed by light and electron microscopic demonstration of the causative bacteria in the vascular lesions. The lesions resolved completely when he was treated with erythromycin. This case demonstrates that bacillary angiomatosis can be an important cutaneous manifestation of immunodeficiency in individuals who are not infected with the human immunodeficiency virus.

Skin biopsies of 33 uremic patients-13 patients on continuous ambulatory peritoneal dialysis (CAPD), 12 on hemodialysis (HD), 8 patients with end-stage renal disease (ESRD) before initiation of dialysis treatment-and 10 healthy volunteers were investigated to determine the number of Langerhans cells (LC) by light microscopy after staining for S-100 protein. The epidermal LC count was significantly lower in patients on CAPD (mean: 62.9 LC/mm2; p = 0.027) and patients on HD (mean: 30.4 LC/mm2; p = 0.0015) compared to controls (mean: 110.1 LC/mm2) and uremic patients before initiation of dialysis treatment (mean: 122.6 LC/mm2). The difference between LC counts of CAPD and HD patients did not reach statistical significance (p = 0.057). There was no relation between LC count and age (p = 0.057) or epidermal width (p = 0.26). No statistically significant correlation could be demonstrated between duration of dialysis and LC count (r = -0.33, p = 0.10). LC counts of CAPD patients with diabetes mellitus (n = 7) were not significantly different from those of nondiabetics (n = 6; p = 0.77). LC counts seem to be normal in uremic patients before dialysis treatment. The reduction in LC density in the skin of dialysis patients may contribute to immunodeficiency of uremic patients on regular dialysis treatment.

In a 78 years old patient with chronic lymphoid leukemia, diabetes mellitus a cat scratch induced disseminated angiomatous papules were observed. In the lesions great number of bacilluses were observed with light -and electron microscope. As a result of antibiotic treatment the lesions regressed without trace. This opportunist infection resulting general symptoms as well, may be regarded as a cutaneous manifestation of immunodeficiency. The adequate antibiotic treatment depends on the exact diagnosis.

This study was designed to evaluate whether myocardial risk factors other than those strictly related to human immunodeficiency virus infection contribute to histologic cardiomyopathic changes in acquired immunodeficiency syndrome patients. We analyzed 91 consecutive adult human immunodeficiency virus-positive autopsy cases (85% acquired immunodeficiency syndrome by Centers of Disease Control criteria) from 1987-1991 for histologic cardiomyopathic changes (e.g. myocyte hypertrophy and myocardial fibrosis). We correlated the presence of cardiomyopathy with the following common myocardial risk factors: hypertension, coronary artery disease, alcoholism, diabetes mellitus, and valve disease. Forty percent of all cases had cardiomyopathy. Hypertension and coronary artery disease were both more common in the cardiomyopathy group (P < 0.05), compared with those human immunodeficiency virus-positive cases without cardiomyopathy. The other myocardial risk factors did not differ significantly between the two groups when compared individually, but when these data were pooled, 67% of cardiomyopathic patients had one or more myocardial risk factors versus 45% in the noncardiomyopathic group (P < 0.05). Cardiomyopathic patients were also more likely to have multiple myocardial risk factors (P < 0.05). Nineteen percent of cardiomyopathic patients had myocarditis versus 11% in the noncardiomyopathic group (P = NS). Patient age, gender, risk factors for human immunodeficiency virus infection (71% intravenous drugs), and history or autopsy findings of viral infection (e.g. cytomegalovirus) did not differ significantly between the two groups. In our patient population, which is heavily weighted towards intravenous drug use, myocardial risk factors other than human immunodeficiency virus are common, and appear to be major contributors to histologic cardiomyopathic changes that might otherwise be attributed to human immunodeficiency virus infection alone.
