Fifteen patients with bacterial endocarditis were treated with vancomycin between 1967 and 1976. The indications for vancomycin therapy were penicillin-cephalosporin allergy in six patients, antibiotic resistant bacteria in six, initial therapy in one and culture-negative endocarditis in two. The causative microorganisms were Staph. epidermidis (four patients), Staph. aureus (two patients), diphtheroids (four patients), viridans streptococci (two patients) and enterococci (one patient). Minimum inhibitory concentrations of vancomycin for these organisms ranged from 0.8 to 3.1 micrograms/ml. The patients received vancomycin for two to 10 weeks (mean five weeks). Cure was achieved in 13 patients, including six with prosthetic valve endocarditis (PVE). Two patients had a relapse of PVE and cultures of blood or heart valve were positive within two months of vancomycin therapy. Vancomycin serum levels did not exceed 50 micrograms/ml, and no serious drug toxicity was encountered in any patient. Three patients had minimal audiogram changes beyond the social hearing range. One patient had mild phlebitis and a rash, and one patient had a transient leukopenia. Vancomycin is an effective nontoxic antibiotic in patients with endocarditis when penicillin or cephalosporin therapy is not appropriate.

Cefoxitin was administered intravenously to 143 patients, 67% of whom were seriously ill. The rate of cure or improvement was 93%. The study was conducted in two phases; the first was an open, controlled clinical comparison of cefoxitin and cephalothin. In this phase, 28 patients received cefoxitin and 29 received cephalothin. In the second phase, cefoxitin alone was used for the treatment of an additional 115 patients. Twenty bacteremic patients treated with cefoxitin were cured or improved in 95% of cases. The infecting organism was eradicated in all bacteremic patients. All of 14 anaerobic or predominantly anaerobic infections were cured or improved. The infecting anaerobic organism was eliminated in 86% of the cases. Twenty-five patients infected by cephalothin-resistant, cefoxitin-susceptible gram-negative rods were cured. Three patients each with infective endocarditis and osteomyelitis were cured. The incidence of adverse experiences was: 1.4% drug eruption; 2% each asymptomatic serum transaminase elevation and leukopenia; and 2.5% asymptomatic eosinophilia. The incidence of severe thrombophlebitis was 5%. No permanent or serious adverse reactions were encountered. Although the numbers of patients in some categories were too small to permit statistical evaluation, I feel that cefoxitin may be a useful new antibiotic for treatment of infections caused by cehalothin-resistant bacteria and by anaerobic organisms.

Semisynthetic penicillinase-resistant penicillins are recommended for therapy of Staphylococcus aureus endocarditis, but evaluation of the efficacy and safety of individual agents has received little attention. At The New York Hospital, 11 heroin addicts and 5 nonaddicts were treated with nafcillin. The 11 addicts did well clinically, but four of the five nonaddicts had severe complications, and three of them died. Important adverse reactions to nafcillin occurred in two patients: one developed leukopenia, and one developed an extensive rash. Methicillin was employed to treat two heroin addicts and four nonaddicts. Five of the six patients were cured bacteriologically, but three patients developed nephritis and one patient developed an extensive rash. Nafcillin appears to be highly efficacious for the treatment of S. aureus endocarditis, yielding results at least equal to those obtained with other drugs. Because adverse reactions appear to occur more frequently with methicillin than with nafcillin, we regard nafcillin as the preferable penicillinase-resistant penicillin for the treatment of S. aureus endocarditis.

Two clinical cases of female patients with hepatic cirrhosis and autoimmune multisystemic involvement with infectious intercurrent are reported. Case 1 presented infective endocarditis and erysipelas on the left thigh. In the course of the clinical picture a cutaneous vasculitis developed in the same place together with autoimmune thrombocytopenia, leukopenia and pulmonary restrictive picture with inflammatory pattern. There are also elevate immune complexes and complement consumption. Case 2 presented erysipelas on the left thigh cutaneous vasculitis and complement consumption. In Case 1 the infective endocarditis was treated with antibiotic therapy during 4 weeks followed by 1 mg/kg corticoid (Prednisone) with thrombocytopenia and leukopenia reversion. Case 2 presented an improvement with antibiotic only. The relation between chronic liver diseases and systemic autoimmune phenomena is commented, special attention being paid to the cutaneous, hematological and pulmonary affection.

We have treated 42 episodes of pediatric infections with sulbactam/ampicillin since 1987. Included were 9 cellulitis, 9 urinary tract infections, 5 cervical lymphadenitis, 4 meningitis, 2 thoracic empyema, 2 osteomyelitis, 2 sepsis, 1 furuncle, 1 perianal abscess, 1 dental abscess, 1 peritonsillitis, 1 salmonellosis, 1 shigellosis, 1 peritonitis, 1 suppurative thyroiditis, 1 infective endocarditis. Responsible pathogens were Escherichia coli in 8, Staphylococcus aureus in 6, Hemophilus influenzae in 2, Streptococcus pneumoniae in 3, Streptococcus viridans in 2, Staphylococcus epidermidis in 1, Bacteroides fragilis in 1, Salmonella D1 in 1, Shigella sonnei in 1, Klebsiella pneumoniae in 1, Enterobacter agglomerans in 1, Acinetobacter calcoaceticus in 1, Enterobacter cloacae in 1, group A beta-hemolytic streptococcus in 1, and polymicrobial infection in 4 cases. Thirty-nine out of 41 (95%) clinically evaluable patients cured and all (34/34) bacteriologically evaluable patients eradicated their pathogens after treatment with sulbactam/ampicillin. Side reactions were seen in five patients; one maculopapular skin rash, one hemolytic anemia, two diarrhea, and one liver function impairment plus leukopenia. All these reactions were transient and did not require interruption of therapy. These results indicate that sulbactam/ampicillin is safe and effective in the treatment of common pediatric infections beyond the neonatal period.

A total of 82 patients involving 83 episodes of proven or presumed bacterial infection were treated with sulbactam/ampicillin. These included 36 cases of soft tissue infection or abscess, four cases of joint or bone infection, 20 cases of respiratory tract infection (17 cases of pneumonia, two of otitis media, and one of tonsillitis), 15 urinary tract infections, three cases of enterocolitis, one case of infective endocarditis, two cases of septicemia, and two of peritonitis. The causative pathogen was isolated in 48 cases (49 infections). These pathogens included Staphylococcus aureus 13 cases, Staphylococcus epidermidis one, Streptococcus pyogenes two, Streptococcus pneumoniae two, Viridans group streptococcus two, peptostreptococcus one, Haemophilus influenzae one, Escherichia coli 12, Enterobacter cloacae three, Proteus mirabilis one, Acinetobacter calcoaceticus one, Salmonella spp. two, Shigella sonnei one, Bacteroides fragilis one, and polymicrobial infections of various combinations in five cases. No bacterial pathogens were isolated in 34 infections, 14 cases of pneumonia and 15 soft tissue infections. Sulbactam/ampicillin was given by intravenous bolus in a dosage range of 75-450 mg/kg/day in four divided doses for variable periods of time depending on the type and severity of the infection. Of a total of 83 episodes of infections, 80 (96.4%) cases were either cured or improved. Bacteriologic eradication also occurred in 46 (93.9%) of 49 infections. Side effects were diarrhea in two patients, acute hemolytic anemia in one patient, and transient elevations in SGOT and leukopenia in one patient. Side effects disappeared upon completion of treatment. Sulbactam/ampicillin is a safe and effective antibiotic for the treatment of common pediatric infections.

Cellular host defenses are considered to be ineffective in bacterial endocarditis; the microorganisms in infected vegetations are protected from phagocytic cells by dense layers of fibrin. To test this hypothesis, nitrogen mustard-induced agranulocytosis and leukopenia were produced in rabbits with right-sided streptococcal endocarditis. The spontaneous sterilization of tricuspid infection observed in the control animals was not present in the granulocytopenic, leukopenic animals. Since the bacterium Streptococcus intermedius is not sensitive to the complement-mediated bactericidal effect of serum and since the animals were not bacteremic during the time of agranulocytosis, an inhibitory effect of the drug on local cellular host defense mechanisms is postulated. We suggest that the spontaneous sterilization of infective endocarditis in the right side of the heart in rabbits is mediated by cellular host defenses.

The first case of Q fever endocarditis that has been diagnosed in Mexico is presented. A 10-year-old girl with discrete subaortic stenosis (SAS) and patent ductus arteriosus (PDA) was seen in December of 1996 with fever, hepatomegaly and splenomegaly. She presented also anemia, leukopenia, hypergammaglobulinemia, positive rheumatoid factor, cryoglobulinemia, antinuclear and anticytoplasmic antibodies (anti-RNA-proteins and anti-DNA). An aortic valve vegetation was seen by echocardiogram. Blood-cultures were negative. Antibody test for Coxiella burnetii was positive. Treatment with doxicyclin was initiated as soon the diagnosis was done. PDA was closed, SAS was liberated and two aortic vegetations were resected. Endocarditis in Q fever occurs when there is predisposing heart disease and/or immunodeficiency. Effective therapy has not yet been established. The diagnosis of Q fever endocarditis is difficult; it should be considered, in case of clinical suspicion of endocarditis with negative blood-cultures.

We report the case of a patient with a Salmonella Kapemba infection, who suffered, 3 weeks after a holiday in Israel, occurrences of high fever and lower back pain for 10 days and icterus for 2 days before admission. Laboratory findings revealed a slight cholestasis and elevation of acute phase protein levels. In the blood culture a Salmonella Kapemba-type organism was cultured. The patient was afebrile for 10 days after hospitalization and then suddenly developed a temperature of 40 degrees C again. At the same time leukopenia, thrombocytopenia, and a rise of D-dimer levels were detected. The patient was admitted to the intensive care unit for a few days, because a disseminated intravascular coagulation was suspected. With magnetic resonance imaging and bone scintigraphy no osteomyelitis or abscess formation could be found. A transesophageal ultrasonography of the heart revealed no signs of endocarditis. In multiple stool cultures no salmonellas could be detected. After antibiotic treatment with ciprofloxacin the fever and lower back pain subsided, and the patient was discharged a fortnight later. This is the first reported case of typhoid fever due to the bacterium Salmonella Kapemba.

We report our experience with linezolid in an investigation of its use against resistant gram-positive bacterial infections. Fifteen patients who had renal failure (n=6), recent liver transplantation (n=5) or surgery (n=6), cancer (n=3), endocarditis (n=2), or human immunodeficiency virus infection (n=1), along with infections due to vancomycin-resistant enterococcus (VRE), and 2 patients with infections due to methicillin-resistant Staphylococcus species who had adverse reactions to vancomycin were treated with linezolid (600 mg every 12 h for 5-42 days (mean+/-SD, 20.5+/-3.5 days). Abscess drainage or prosthetic device removal was undertaken. Microbiological cure occurred in all 10 patients who completed therapy, and all 7 patients alive at follow-up were free of infection. No deaths were attributable to the index infection. Adverse events associated with linezolid use were mild leukopenia in 1 patient and nausea in another. It appears that administration of linezolid, in conjunction with surgical intervention or device removal, is an effective treatment option for serious resistant gram-positive bacterial infections.
