Definitions

  • This invention relates to Directed Human Immune Globulin for the prevention and treatment of staphylococcal infections. III. BACKGROUND OF THE INVENTION
  • staphylococci have become important causes of infection in hospitalized patients. Because of their high prevalence on the skin, staphylococci are ideally situated to cause serious infections in debilitated or immunosuppressed patients.
  • the staphylococcal species most frequently pathogenic in humans are Staphylococcus aureus (SA) and
  • SE Staphylococcus epidermidis
  • SE has emerged as a common cause of neonatal nosocomial sepsis in premature infants.
  • SE infections frequently occur in immature babies that have received parenteral nutrition.
  • Premature babies have impaired immunity with deficiencies in antibodies, complement and neutrophil function.
  • Lipid infusion is now a standard ingredient of parenteral nutrition therapy in many nurseries and may further impair immunity to bacterial infection as disclosed by Fischer and colleagues (Lancet, 1980; 2:819-20).
  • Recent studies have associated coagulase negative staphylococcal bacteria in neonates with lipid emulsion infiision (Freeman and colleagues, N. Engl. J. Med, 1990).
  • the opsonic assays that are currently used are slow and cumbersome for screening blood, plasma or immune globulin for antibodies to SE. It would be important to have a rapid antigen binding assay to screen for SE antibody, if that assay further correlated with opsonic activity in vitro and protection in vivo.
  • Yoshida and collegues (J Microbiol, 1976) reported on a virulent strain of SE that infected mature mice with 90 - 100% of mice dying within 24 - 48 hours. This model is very different from that seen in patients and may represent an unusual type of SE infection. When they analyzed 80 fresh isolates of SE from humans, they were not able to kill mice. Non-human antibody to a new SE surface polysaccharide protected the mice from the virulent SE strain. A later report by Yoshida and colleagues (J Med
  • mice In the animal model described by Yoshida, Ichiman and colleagues mature, non-immunosuppressed mice were used and death was considered to be related to toxins not sepsis (Yoshida and colleagues, J.
  • Antibody provides protection in humans against certain .
  • encapsulated bacteria such as Hemophilus influenzae and Streptococcus pneumoniae.
  • Individuals such as young infants who are deficient in antibody are susceptible to infections with these bacteria and bacteremia and sepsis are common. When antibody to these bacteria is present it provides protection by promoting clearance of the bacteria from the blood. Immunoglobulin with antibody to H. influenzae and S. pneumoniae protects infants from sepsis with these bacteria.
  • the article by Espersen and colleagues, (Arch Intern Med, 1987) discloses the use of an antigen binding RIA assay to analyze IgG antibody to SE in patients with uncomplicated bacteremia and those with bacteremia and endocarditis.
  • This assay used an ultrasonic extract of SE to identify SE specific IgG (the surface antigen in this study differs from the antigen used by Yoshida and colleagues which was obtained by a different method; gentle sonic oscillation). None of the patients with uncomplicated bactermia had IgG antibodies to SE. These data would suggest that IgG is unnecessary for effective eradication of SE from the blood. In addition, 89% of bacteremic patients with endocarditis developed high levels of IgG to SE. In these patients, IgG was not protective since high levels of IgG antibody (which may have developed late) were associated with serious bacteremia and endocarditis.
  • SE is an important pathogen in certain high risk individuals, such as patients with foreign body implants, premature neonates and immunosuppressed patients. Accordingly there is a need for a human immune globulin that would prevent or treat SE infections such as, sepsis or endocarditis and promote clearance of SE from the blood of such high risk people. IV. SUMMARY OF THE INVENTION
  • Directed Human Immune Globulin is different from standard human immune globulin preparations in that it has high levels of human anti-staphylococcal antibodies that react with surface antigens of S. epidermidis and enhance phagocytosis and killing of S. epidermidis in vitro, (opsonophagocytic bactericidal activity greater than 80%).
  • Directed Human Immune Globulin for S . epidermidis enhances immunity in vivo and prevents lethal infection as well as enhancing clearance of S. epidermidis from the blood in conditions of immaturity and impaired immunity. This is surprising since
  • Immune Globulin when given intravenously immediately provides specific antibodies to promote phagocytosis and killing of S. epidermidis by
  • a further advantages of the present invention is that by providing opsonic antibody to immature or immunosuppressed patients infected with SE, antibiotic therapy may be enhanced by improved S. epidermidis clearance from the blood or site of infection. Another advantage is that since Directed Human Immune Globulin given intravenously or intramuscularly can raise the level of antibodies in the blood of patients, Directed Human Immune Globolin could prevent S. epidermidis from causing bacteremia and local infections.
  • the method of producing the Directed Human Immune Globulin for S. epidermidis involves:
  • a) screening plasma (pools of immunoglobulin or plasma; immunoglobulin or immunoglobulin preparations) for antibodies to S. epidermidis using an in vitro antigen-binding assay: (ELISA), followed by confirmation of functional activity using an in vitro opsonophagocytic bactericidal assay (bactericidal activity greater than 80%).
  • ELISA in vitro antigen-binding assay
  • Directed Human Immune Globulin for SE could be used to prevent lethal SE infections in high risk patients such as neonates and adults in intensive care units or patients with in-dwelling foreign bodies such as venous and arterial catheters or ventricular shunts. Directed Human Immune Globulin could also be used in addition to antibiotics as adjunctive therapy to enhance bacterial clearance in patients treated for SE infections.
  • Standard Human Immunoglobulin and Directed Human Immune Globulin for JJL epidermidis as used in this application are defined as follows: Standard Human Immunoglobulin - immune human globulin that was prepared by pooling immunoglobulin from many donors, without selecting donors or screening the immunoglobulin to ensure antibody acitivity for S. Epidermidis.
  • Figure 1 shows that when several pools of human standard intravenous immunglobulin were analyzed, there was a marked difference in the antibody activity to S. epidermidis as measured by an antigen binding assay (ELISA, highest O.O. reading at 1 1/2 hrs using 1:100 Dil). These were large pools of IgG, purified by several companies using various techniques. Of three pools with the highest titers, two were from Cutter Laboratories, Berkeley
  • Figure 2 shows that using an in vitro functional (opsonic) assay that measures the ability of immunoglobulin to promote phagocytosis and killing of S. epidermidis by neutrophils in the presence of complement, that opsonic activity is also variable in various lots and preparations of standard human immunoglobulin.
  • the figure also shows that the immunoglobulins identified by ELISA as having high levels of antibody to S. epidermidis also had high levels of functional antibody in vitro. This is critical since this study shows that IgG that binds to TCA extracted S. epidermidis antigen will promote phagocytosis and killing of S. epidermidis. Therefore, using in vitro screening assays, one could select a Directed Human Immune Globulin for S.
  • epidermidis that would have reliable levels of antibody to prevent or treat S. epidermidis infections.
  • FIG. 3 shows that Directed Immune Globulin protects animals from developing prolonged S. epidermidis bacteremia while standard immune globulin did not.
  • Animals treated with Directed Immune Globulin had lower peak bacteremia levels (9.2 ⁇ 10 2 vs. 6.5 ⁇ 10 3 ) and cleared the bacteremia more efficiently (at 72 hours, 5 bact. per ml vs. 380 bact. per ml; geometric mean level).
  • 72 hours after infection 18/24 (75%) animals given Directed Immune Globulin had cleared their bacteremia and 100% survived, while only 4/20 (20%) animals given standard immune globulin died and only 1/16 (6%) cleared their bacteremia during that 72 hour period.
  • Directed Immune Globulin enhanced S. epidermidis
  • Staphylococcal Strains Although any S. epidermidis strains could be used, in these experiments we used two strains from the American Type Culture Collection, Rockville, MD (ATCC #31432 and ATCC #35984). A clinical isolate (Hay) from the blood of a child with S. epidermidis sepsis was also used and is also on deposit at the American Type Culture Collection.
  • Immunoglobulin Standard Intravenous Immunoglobulin was used in these experiments to represent large immunoglobulin pools.
  • Trichloroacetic Acid (TCA) Antigen Extraction Staphylococcus epidermidis strains ATCC #35984, ATCC #31432 and Hay were grown to log phase at 37°C in 1000 ml of Tryptic Soy Broth (Difco). The bacteria were then centrifuged at 2500 RPM for 10 minutes and the supernatant was aspirated and discarded.
  • the bacterial button was resuspended in 200 ml of 2% trichloroacetic acid (TCA) and stirred overnight at 4°C. The mixture was then centrifuged at 2500 RPM for 10 minutes and the supernatant aspirated. To the supernatant, 4 volumes of absolute ethanol were added and refrigerated overnight at 4°C. After centrifiigation at 2500 RPM for 10 minutes, the supernatant was removed and discarded. Then, five milliliters of normal saline was added to the antigen precipitate, it was cultured to ensure sterility and then lyophilized for storage.
  • TCA 2% trichloroacetic acid
  • Immunoabsorbent Assay S. epidermidis Antigen was dissolved in carbonate buffer at a concentration of 25 micrograms/ml. To each well of A 96-well flat-bottomed microtiter plate (NUNC, Roskilide, Denmark) 100 microliters were added and stored at 4°C until used. Immunoglobulin was diluted to 1 % and 2-fold dilutions prepared in phosphate-buffered saline-Tween . To each weir was added 100 microliters of the serial dilutions and the plates were incubated for 1 hour at 4°C. The plates were washed four times with H 2 O-Tween .
  • neutrophil mediated bactericidal assay was used. Neutrophils were isolated from adult venous blood by dextran
  • a suckling rat model was used to determine the in vivo activity of antibody to S. epidermidis.
  • Wistar rats (2 days old) were given 0.2 ml of 20% Intralipid (Cutter, Berkeley California,) intraperitoneally at 0800 and 1400.
  • 0.2 ml of 20% intralipid at 0800 and 1400 and 0.2 ml of 5% immunoglobulin or serum was given IP.
  • 0.05ml approximately 0.05ml (approx. 5 ⁇ 10 7 ) mid log phase S. epidermidis were injected subcutaneously just cephalad to the tail.
  • Suckling rats less than 24 hours old also develop lethal S.
  • epidermidis sepsis when infected with 10 7 -10 8 S. epidermidis subcutaneously.
  • 0.01 ml of blood was obtained from the tails of the suckling rats, 24, 48, and 72 hours after infection.
  • The. blood was collected under sterile conditions in micropipettes and serially diluted in Tryptic Soy Broth (Difco). Bacteria were subcultured onto plates to ensure S. epidermidis bacteremia and all animals were followed five days to determine survival.
  • epidermidis based on in vitro assays that measured antibody binding to TCA S. epidermidis antigens and opsonic antibody activity determined by in vitro testing. Serum from a single donor also had good opsonic activity for S. epidermidis (> 80% opsonophagocytic bactericidal activity). While serum and plasma from several individuals have been studied only this donor had high opsonic activity. Therefore donor screening could detect individual blood or plasma donors that could contribute immunoglobulin that could be pooled as an alternate method to produce a Directed Human Immune Globulin for S. epidermidis. In addition blood or plasma units could be screened for pooling as well. Animal Protection Studies
  • Table 1 shows the effect of Directed Human Immunoglobulin for S. epidermidis (40R09) (which was selected by ELISA and opsonic assay screening) compared to standard human immunoglobulin (that had moderate activity for S. epidermidis) and saline control. Table 1 shows that untreated control animals had about a 50% mortality while animals given Directed Immune Globulin for S. epidermidis were fully protected (NO mortality).
  • Table 2 demonstrates that Directed Immune Globulin produced in rabbits by immunization (S. epidermidis vaccine) produced survival similar to Directed Human Immune Globulin produced by screening immunoglobulin for antibody to S. epidermidis. Immunization of individuals with S.
  • Table 3 shows that intralipid causes a dose related increased mortality in suckling rats infected with S. epidermidis. Control animals receiving Intralipid alone had 100% survival (43/43) while immature rats given 16 gm/kg of Intralipid had only 46% survival (6/13). The high dose of Intralipid appears to impair the immune system sufficiently to allow the normally avirulent S. epidermidis to overwhelm the baby animals.
  • Table 4 shows that normal 3 day old suckling rats not given Intralipid, but infected with S. epidermidis develop bacteremia.
  • Table 1 shows the Directed Human Immune Globulin for S. epidermidis (selected by screening standard immunoglobulin for opsonic or antigen binding activity for S. epidermidis. provides complete protection from lethal infection in the setting of impaired immunity with. Intralipid while standard immune globulin (with moderate antibody levels) had only partial protection (1 out of 5 aminals died compared to about 50% with saline).
  • Directed Human Immune Globulin 8016A >90% opsonic activity, versus standard human immune globulin, 8007 A ⁇ 50% opsonic activity showed that the Directed Human Immune globulin also provided enhanced survival (8016A-64/95 (67%) vs. 8007A-39/90 (43%)) over standard human immune globulin. Even more striking was the fact that the Directed Human Immune Globulin decreased the peak level of S. epidermidis
  • epidermidis enhanced bacterial clearance from the blood and could be an effective prophylactic or therapeutic modality even in the immature host with impaired immunity.
  • Many of the animals treated with standard human immune globulin remained bacteremic 72 hours after infection while only 1/20 animals was still bacteremic at 72 hours after receiving the Directed Human Immune Globulin.
  • the mean bacteremia level at 72 hours was markedly different (bacteremia with Directed Human Immune Globulin 0.5 ⁇ 10 1 vs. bacteremia with standard human immune globulin 3.8 ⁇ 10 2 ).
  • rabbit Directed Immune Globulin for S. epidermidis was produced by immunizing rabbits with S. epidermidis vaccine.
  • the vaccine induced Directed Immune Globulin was compared with Directed Human Immune Globulin produced by screening immunoglobulin for antibody to S. epidermidis (Table 2).
  • Vaccine induced Directed Immune Globulin had similar protective activity to Directed Human Immune Globulin produced by screening (9/11 vs. 12/13 survived) and each was better than controls (11/19 survived).
  • epidermidis are not pathogenic in normal people. However, in babies with an immature immune system or impaired immunity as is seen with intralipid, S. epidermidis may cause sepsis and death. It is critical therefore, that any animal model to test antibody effectiveness should include these factors. To our knowledge this is the first time that antibody to Staphylococcus epidermis has been shown to provide protection and enhance bacterial clearance in an immature and/or immunosuppressed host. Intralipid given in dosage up to 16 gm/kg did not cause death in any baby animals (controls, table 3). In the absence of
  • Intralipid the 3 day old animals will become bacteremic with S. epidermidis after infection, but will clear the infection over 72 hours and survive (Table 4). However, Intralipid did impair immunity in a dose related fashion and when the 3 day old animals were infected with S. epidermidis lethal sepsis occurred in up to 67% of the animals. Baby rats in the first day of life also do not clear bacteriemia well (due to immature immunity) and develop lethal sepsis. In these models baby rats were unable to clear the S. epidermidis bacteremia and developed lethal sepsis. Directed Human Immune Globulin was able to enhance survival and promote bacterial clearance while standard human immune globulin did not enhance clearance (Fig 3).
  • Standard model starts IL on day 2 of life with infection after last IL dose on day 3 if full 4 doses given.
  • *IL started on day I of life with infection after the 4th dose on day 2.
