The clinical results obtained with fraction IgGAM are reported. Different types of antibody deficiency syndromes have successfully been treated : 8 cases of Bruton-type agammaglobulinemia. In one of these case a tenacious Pseudomonas infection cleared off during the treatment. Two cases of non sex-linked familial agammaglobulinemia. Three cases of isolated IgM deficiency. Five cases of isolated IgA deficiency. Five cases with Soothill type IgA deficiency associated with high IgE levels. Five cases of septicemia of the new-born. Three cases with acquired agammaglobulinemia and in the premature infant (5 cases). No side-effects nor appearance of anti-IgA antibodies have been observed.

Ticarcillin was evaluated in 82 neonates and young infants with suspected sepsis and in 16 older children with chronic Pseudomonas infection of the mastoids. The infants also received kanamycin. Individual ticarcillin doses of 75 or 100 mg/kg were given every four, six, or eight hours by intramuscular injection or by a 30-minute intravenous infusion. Mean plasma concentrations one hour after a dose were from 125 to 189 microgram/ml, depending on dosage, age, and maturity. Mean plasma half-lives were approximately 5 hours in the first week of life, 2 hours in infants from 1 to 8 weeks, and 0.9 hours in older children. Volume of distribution was approximately twice as great in infants as in children, and plasma clearance rates correlated inversely with age. Limited efficacy data suggest that ticarcillin is a suitable alternative to ampicillin or carbenicillin, when given concurrently with an aminoglycoside, for newborn infections. When given for several days before mastoidectomy and tympanoplasty, ticarcillin sterilized the mastoids in the majority of patients. A new dosage schedule for ticarcillin in pediatric patients is proposed.

In comparison with polyvalent immunoglobulins, Pseudomonas immunoglobulin (Psomaglobin) is enriched several times in antibodies to Ps. lipopolysaccharide antigens and exotoxin A as well as lipid A. The resulting protective action which is superior to polyvalent immunoglobulins in infections with Pseudomonas, was demonstrated both in cell culture (protection against cytotoxicity of Ps. exotoxin A in heart muscle cells) and in animal models of sepsis. In patients suffering from Ps. pneumonia and Ps.-sepsis clinical improvement is seen after application of this immunoglobulin and also in quantifiable by scoring systems, the unequivocal proof of lowering lethality by using this specific immunoglobulin in Pseudomonas infection is to be shown however.

Intravenous inoculation of 3.4 x 10(10) to 7.4 x 10(10)Pseudomonas aeruginosa organisms into rhesus monkeys 4 days after intravenous or intratracheal inoculation of 2.0 to 2.5 mg of vincristine sulfate resulted in fatal sepsis in eight of nine monkeys. After intramuscular administration, in two equal doses, of 5 mg of tobramycin, gentamicin, and colistin per kg per day beginning 16 hr after challenge, 4 of 11, 4 of 11, and 3 of 10 monkeys died, respectively. Administration of daily doses of 100 to 400 mg of carbenicillin per kg was followed by death in 5 of 12. Duration of illness in the surviving monkeys in each therapy group was similar. Under the conditions of this study, prior administration of vincristine sulfate resulted in a decrease in leukocytes and enhanced susceptibility to Pseudomonas infection. Using this model for studies of comparative efficacy of antibiotics, we observed comparable results after treatment with tobramycin, gentamicin, colistin, and carbenicillin.

Pseudomonas aeruginosa has emerged as an important pathogen during the past two decades. It causes between 10% and 20% of infections in most hospitals. Pseudomonas infection is especially prevalent among patients with burn wounds, cystic fibrosis, acute leukemia, organ transplants, and intravenous-drug addiction. P. aeruginosa is a common nosocomial contaminant, and epidemics have been traced to many items in the hospital environment. Patients who are hospitalized for extended periods are frequently colonized by this organism and are at increased risk of developing infection. The most serious infections include malignant external otitis, endophthalmitis, endocarditis, meningitis, pneumonia, and septicemia. The likelihood of recovery from pseudomonas infection is related to the severity of the patient's underlying disease process. The introduction of the antipseudomonal aminoglycosides and penicillins has improved substantially the prognosis of these infections. Ticarcillin and carbenicillin have been especially beneficial in neutropenic patients; however, prompt institution of therapy is mandatory for optimal benefit. Many new drugs with antipseudomonal activity, including penicillins, cephalosporins, and other beta-lactams, have been introduced in recent years and offer the potential for new approaches to therapy for these infections.

Carbenicillin and ticarcillin are penicillins which were initially developed as agents to treat serious Pseudomonas infections in the seriously ill hospitalized patient. These drugs have made a major contribution to improved survival in the neutropenic patients with Pseudomonas infection, the burn patient and to the care of the patient with cystic fibrosis. Areas of use for the compounds have enlarged to include aspiration pneumonitis in hospitalized patients, intra-abdominal and pelvic sepsis, and infections due to Proteus and Enterobacter species. Careful attention to the pharmacology of the agents is necessary to achieve clinical and bacteriologic success and to avoid the toxic side-effects such as bleeding and hypokalemia associated with the use of these agents. A decade of use has shown that the agents have remained effective agents in institutions in which their use has not been abused. It is too early to clearly position azlocillin, mezlocillin, and piperacillin. In the next few years the role of these potent compounds will be established. As noted in this review, these three agents have been used with success to treat all of the aforementioned infections. With these drugs it is also essential that the physician closely correlate in vitro data and the human pharmacology of the drugs if he or she wishes to achieve the most effective response from the agents.

Pseudomonas aeruginosa septicemia rarely occurs in non-immunocompromised adults. We present a case of septic shock following Pseudomonas aeruginosa pneumonia in a previously healthy 48-year-old woman. The onset was sudden, with back pain, pyrexia and shock. Chest radiographs revealed pneumonia, and Pseudomonas aeruginosa was identified from blood and sputum cultures. Therapy with dopamine, piperacillin and fluid replacement led to a prompt recovery. Laboratory tests failed to reveal any immunological deficits. Including this case, only five cases of Pseudomonas aeruginosa septicemia in patients though to be non-immunocompromised have been reported. Two remarkable features of this type of Pseudomonas infection are apparent: i) it commonly develops from pneumonia and ii) it has a better prognosis than that in immunocompromised hosts.

Pseudomonas aeruginosa infection is unusual in individuals with human immunodeficiency virus infection, and it most often occurs in the setting of other risk factors, such as neutropenia or cytotoxic drug use. We noted an increasing number of pulmonary isolates of this organism in our clinic population and sought to describe the clinical correlates of this finding. Our study consisted of a retrospective review of the microbiology, radiology, and clinical records of 1,852 HIV-seropositive adults seen at a university-based outpatient AIDS clinic. We identified 16 individuals with Pseudomonas bronchopulmonary infection. All subjects had advanced HIV disease with prior AIDS diagnoses, and mean CD4 counts of 25/mm3 (0.025 x 10(9)/L). Pseudomonas was the sole pulmonary pathogen in 14 of 16 patients and was associated with new chest X-ray abnormalities in 14 cases. Four individuals had acute pseudomonal pneumonia with sepsis; this presentation was associated with hospitalization and other known risk factors for Pseudomonas infection. In contrast, 12 patients had more indolent, community-acquired infection, which had a low mortality rate and occurred in the absence of other risk factors. Survivors of the initial bout of Pseudomonas infection had an 86% relapse rate despite a median survival of only 4.5 months. This pattern of pseudomonal disease is reminiscent of cystic fibrosis and suggests a role for maintenance therapy.

A controlled study was performed to evaluate the efficacy of human hyperimmune plasma (HIP) for protecting burned mice from Pseudomonas infection. The HIP was prepared from healthy volunteers immunized with endotoxin protein (Ep) of Pseudomonas aeruginosa. It contained antibody against Ep up to the titre higher than 1:128. Mice with full-thickness burn of 13% TBSA, infected by subeschar injection of 0.2 ml P. aeruginosa (CFU/ml), were treated with HIP at 6 hrs and 18 hrs postburn. The survival rate of the former on the 7th day was 45%, while in mice treated with normal plasma (NP) was 14% and in control mice 10% (P < 0.01). If the HIP was given 18h after burn, the survival rate was 43%, while in mice with NP was 39% and in control 42% (P > 0.05). The results indicate that HIP is able to protect burned mice from Pseudomonas infection giving at 6 hrs postburn (pre sepsis) but not at 18 hrs postburn (post sepsis).

Neonatal sepsis is a life-threatening emergency and any delay in treatment may cause death. Initial signs of neonatal sepsis are slight and nonspecific. Therefore, in suspected sepsis, two or three days empirical antibiotic therapy should begin immediately after cultures have been obtained without awaiting the results. Antibiotics should be reevaluated when the results of the cultures and susceptibility tests are available. If the cultures are negative and the clinical findings are well, antibiotics should be stopped. Because of the nonspecific nature of neonatal sepsis, especially in small preterm infants, physicians continue antibiotics once started. If a baby has pneumonia or what appears to be sepsis, antibiotics should not be stopped, although cultures are negative. The duration of therapy depends on the initial response to the appropriate antibiotics but should be 10 to 14 days in most infants with sepsis and minimal or absent focal infection. In infants who developed sepsis during the first week of life, empirical therapy must cover group B streptococci, Enterobacteriaceae (especially E. coli) and Listeria monocytogenes. Penicillin or ampicillin plus an aminoglycoside is usually effective against all these organisms. Initial empirical antibiotic therapy for infants who developed sepsis beyond the first days of life must cover the organisms associated with early-onset sepsis as well as hospital-acquired pathogens such as staphylococci, enterococci and Pseudomonas aeruginosa. Penicillin or ampicillin and an aminoglycoside combination may also be used in the initial therapy of late-onset sepsis as in cases with early-onset sepsis. In nosocomial infections, netilmicin or amikacin should be preferred. In cases showing increased risk of staphylococcal infection (e.g. presence of vascular catheter) or Pseudomonas infection (e.g. presence of typical skin lesions), antistaphylococcal or anti-Pseudomonas agents may be preferred in the initial empirical therapy. In some centers, third-generation cephalosporins in combinations with penicillin or ampicillin have been used in the initial therapy of early-onset and late-onset neonatal sepsis. Third-generation cephalosporin may also be combined with an aminoglycoside in places where aminoglycoside-resistance to this antibiotic is high. However, third-generation cephalosporins should not be used in the initial therapy of suspected sepsis, because 1) extensive use of cephalosporins for initial therapy of neonatal sepsis may lead to the emergence of drug-resistant microorganisms (this has occurred more rapidly as compared with the aminoglycosides), 2) Antagonistic interactions have been demonstrated when the other beta-lactam antibiotics (e.g. penicillins) were combined with cephalosporins. Infections due to gram-negative bacilli can be treated with the combination of a penicillin-derivative (ampicillin or extended-spectrum penicillins) and an aminoglycoside. Third-generation cephalosporins in combination with an aminoglycoside or an extended-spectrum penicillin have been used in the treatment of sepsis due to these organisms. Piperacillin and azlocillin are the most active of extended-spectrum penicillins against Pseudomonas aeruginosa. Among the third-generation cephalosporins, cefoperazone and ceftazidime possess anti-Pseudomonas activity. Ceftazidime was found to be more active in vitro against Pseudomonas than cefoperazone or piperacillin. New antibiotics for gram-negative bacteria resistant to other agents are carbapenems, aztreonam, quinolones and isepamicin. Enterococci can be treated with a cell wall-active agent (e.g. penicillin, ampicillin, or vancomycin) and an aminoglycoside. Staphylococci are susceptible to penicillinase-resistant penicillins (e.g. oxacillin, nafcillin and methicillin). Resistant strains are uniformly sensitive to vancomycin. A penicillin or vancomycin and an aminoglycoside combination result in a more rapid bacteriocidal effect than is produced by either dr
