Two children with systemic E. coli and candidial infections developed disseminated intravascular coagulation (DIC). Bone marrow examination in both cases showed histiocytic hemophagocytosis, consistent with the diagnosis of the hemophagocytic syndrome. Histiocytic hemophagocytosis in the bone marrow, one of the markers of the activated mononuclear phagocyte system, might be common in patients with severe sepsis and DIC, especially in immunodeficiency.

A case of signet cell carcinoma associated with AIDS is presented. A 50-year old Japanese man with hemophilia A was suffering from human immunodeficiency virus (HIV) infection, the result of multiple injections of clotting factor concentrates. A diagnosis of signet cell carcinoma of the stomach was reached upon endoscopic and histological examinations. Opportunistic infections of esophageal candidiasis and candida septicemia occurred. The patient died of repeated gastrointestinal bleeding and cachexia. Although there is a possibility of the patient having a coincidential carcinoma along with AIDS, the HIV infection, perhaps, had a role in causing signet cell cercinoma.

Long-term management of cytomegalovirus (CMV) retinitis by intravitreal injection of ganciclovir was evaluated in ten patients with acquired immune deficiency syndrome (AIDS). Patients were unable to tolerate systemic ganciclovir because of severe neutropenia (8 cases), catheter-induced sepsis (1 case), or the need to continue therapy for human immunodeficiency virus (HIV) with zidovudine (ZDV) (1 case). All patients had a favorable response to initial treatment. Cytomegalovirus retinitis progressed in four fellow eyes in which treatment was deferred. Vision improved or remained stable in all but one eye. Patients were followed for a mean of 4 months and received an average of 16.6 intravitreal injections in each eye. Relapse occurred late in the course while on maintenance treatment in five eyes (33%). There was no evidence of toxicity from repeated intravitreal injections. Treatment was very well tolerated. The only severe complication in a total of 249 injections was a single case of Staphylococcus epidermidis endophthalmitis which responded to intravitreal antibiotic treatment. Intravitreal ganciclovir is an effective alternative to systemic ganciclovir in those patients with severe neutropenia and in those patients who desire to remain on systemic ZDV.

2',3'-dideoxycytidine (ddC) inhibits replication of the immunodeficiency inducing strain of feline leukemia virus (FeLV-FAIDS) in vitro at concentrations ranging from 1-10 micrograms/ml. Additive antiviral effect is achieved when ddC is combined with either human recombinant alpha interferon (IFN alpha) or tumor necrosis factor (TNF) plus IFN alpha. Initial in vivo pharmacokinetic studies in cats, utilizing bolus intravenous administration of ddC (20 mg/kg), resulted in peak plasma concentrations of 15 micrograms/ml 1 min after administration and a half-life of approximately 1 h. These values could not be augmented with high levels of the deaminase blocker tetrahydrouridine administered prior to or concurrently with ddC. In vivo trials utilizing multiple, daily intravenous injections of ddC could not prevent the development of persistent viremia in cats infected with FeLV-FAIDS. To enhance ddC pharmacokinetics and antiviral activity, controlled release capsular implants were developed by blending ddC with a copolymer consisting of DL-lactide glycolide and hydroxypropyl cellulose, which was melt-spun into fibers and encapsulated in a sheath of polyethylene glycol for subcutaneous implantation. Pharmacokinetic studies, conducted in cats receiving an average dose of 600 mg of ddC, indicated an average peak plasma concentration of 17 micrograms/ml achieved at 6 h post implantation with 3.5 micrograms/ml noted at 48 h; and an extension of plasma half-life from 1.5 (bolus subcutaneous injection) to 20 h. sustained plasma concentrations of 1.5 to 10 micrograms/ml, equivalent to ddC levels previously shown to have anti-FeLV activity in vitro, were maintained throughout a 72 h period. Implantation devices could be replenished every 48 h and elevated plasma levels were sustained for four weeks without signs of clinical toxicity, sepsis or significant alterations in the hemogram. Initial clinical trials employing controlled release capsular ddC implants in vivo indicate significant retardation of FeLV-FAIDS replication throughout a four week treatment period.

The Centers for Disease Control surveyed 1,630 chronic hemodialysis centers in the United States in 1987 in conjunction with the annual facility survey done by the Health Care Financing Administration. Information was obtained on the following diseases and practices: 1) hepatitis B virus (HBV) infection in patients and staff members; 2) infection control procedures for hepatitis B surface antigen (HBsAg)-positive patients; 3) frequency of HBsAg serologic screening; 4) use of hepatitis B vaccine; 5) non-A, non-B hepatitis in patients and staff members; 6) pyrogenic reactions and septicemia; 7) dialysis dementia; 8) new dialyzer syndrome; 9) high flux dialysis; 10) reuse of dialyzers, dialyzer caps, bloodlines, transducer filters; 11) cleaning and disinfection procedures; and 12) human immunodeficiency virus (HIV) infection. The response rate to a mailed questionnaire was 91%. These 1,486 centers represented 97,225 patients and 27,123 staff members. During the last 12 years, the incidence of HBV infection decreased from 3.0% to 0.2% among patients and from 2.6% to 0.1% among staff members. Over the same time, the prevalence of HBsAg-positivity declined from 7.8% to 1.7% among patients and from 0.9% to 0.4% among staff members. Hepatitis B vaccine was given by 88% of the centers. By the end of 1987, 14% of susceptible patients and 49% of susceptible staff members had received all three doses of hepatitis B vaccine. From 1982 to 1987, as a result of receiving vaccine, the prevalence of antibody to HBsAg (anti-HBs) increased from 12% to 18% among patients and from 18% to 50% among staff. The incidence of non-A, non-B hepatitis in 1987 was reported to be 1.2% among patients and 0.2% among staff members. Fourteen percent of the centers reported pyrogenic reactions among their patients, and 46% reported septicemia in the absence of pyrogenic reactions. Pyrogenic reactions were significantly more likely to be reported by centers that practiced high flux dialysis. The reported incidence of dialysis dementia among hemodialysis patients was 0.2%, with a case fatality rate of 29%. Among patients developing dialysis dementia, the case fatality rate was higher in those centers that used deionization (DI) without reverse osmosis (RO) (47%) compared with centers that used RO (28%) (not significant, p greater than 0.05). In 1987, 64% of centers reported that they reused disposable dialyzers. These centers treated 70% of the dialysis patient population.(ABSTRACT TRUNCATED AT 400 WORDS)

This retrospective study details the findings and outcome in 34 homosexual men, out of a total of 177 patients, who underwent surgery for non-condylomatous perianal disease over a 2-year period. Of 34 homosexuals 20 presented with anorectal sepsis compared with 11 of 79 heterosexual male patients (X2 = 24.07, P less than 0.001). Lesions included chronic intersphincteric abscess (eight patients), anal fistula (seven patients) and chronic intersphincteric abscess and fistula (five patients). Anal fissure occurred in 15 patients, anal ulcer in three, skin tags in six, haemorrhoids in two and Kaposi's sarcoma in one. Eight patients were human immunodeficiency virus (HIV) antibody negative, four were asymptomatic HIV antibody positive, 12 had symptomatic HIV infection using the Centers for Disease Control classification and in ten patients HIV status was unknown. Irrespective of the type of surgery performed, healing occurred within 6 weeks of operation in all HIV antibody negative patients, all asymptomatic HIV antibody positive and in only one of nine patients with symptomatic HIV infection. Eight of nine patients with symptomatic HIV infection failed to heal by this time (X2 = 8.98, P less than 0.05). These findings suggest that the prevalence of anorectal sepsis in homosexual men is high and that symptomatic HIV infection is an important determinant of progress after surgery.

A 62 year-old man had suffered from gout and mild renal insufficiency since he was 40 years old. He was admitted to our hospital complicated by a productive cough, high fever and a right swollen knee joint. The chest radiographs demonstrated a left upper lobe infiltration shadow. Streptococci pneumoniae were found in the sputum, arterial blood and synovial fluid of the right knee joint, suggesting a severe pneumonia followed by pneumococcal septicemia which led to purulent arthritis. He was treated with cefamandole (CMD) and penicillin G (PC-G) for one week, but the chest X-ray findings were not improved. After treatment with cefbuperazone (CBPZ) and latamoxef (LMOX), his fever and other symptoms gradually resolved. Streptococcus pneumoniae is an uncommon organism of septic arthritis. Pneumococcal arthritis in a patient without immunodeficiency such as this case is very rare, and has not been reported in Japan.

Patients treated with chronic dialysis have a high risk of acquiring viral infections and blood transfusions are commonly considered to be the vehicle of transmission. In Brazil this source is implicated in infection of 15 percent of patients developing acquired immunodeficiency syndrome (AIDS). So, we evaluated the relative risk of our patients in dialysis becoming infected with human immunodeficiency virus (HIV), the virus associated with the AIDS. An enzyme immunoassay showed 6 of 104 patients on dialysis to have antibodies to HIV. In five infection with HIV was confirmed by Western blot tests. Investigation of other risk factors for AIDS showed that blood transfusion was the most likely cause of contamination. There was no correlation between HIV and HBV infections. Only one patient had leucopenia and low OKT4/T8 ratio and she died 90 days after sorologic diagnosis of HIV infection; the cause of death was encephalopathy and sepsis. Two patients died after 4 and 16 months victims of cardiocirculatory problems (non-AIDS related causes). Three patients remain asymptomatic on chronic hemodialysis 20, 36 and 37 months after diagnosis of HIV infection.

Neonatal host defense simulates a clinical state of immunodeficiency that predisposes the preterm and term newborn to overwhelming bacterial sepsis. There are various immunologic components that are deficient in the newborn and new methods to enhance their function. Defects in both the quantitative and qualitative aspects of the neonatal phagocyte contribute substantially to the immaturity of neonates' immune systems. The neonate lacks an adequate number of granulocyte bone marrow progenitor cells, and has a decreased neutrophil storage pool and an increased tendency to peripheral neutropenia during neonatal sepsis. Additionally, the neonatal granulocyte demonstrates altered physiologic function compared with that found in the adult with respect to chemotaxis, phagocytosis, oxidative metabolism, and bacterial killing. Some recent clinical studies have suggested the benefit of using adult neutrophil transfusions as adjuvant treatment during neonatal bacterial sepsis, yet other studies have found the use of polymorphonuclear neutrophil leukocyte transfusions to be inconclusive. Reduced circulating immunoglobulins and impaired production of specific antibody have also led to recent trials in the use of prophylactic intravenous immunoglobulin in preterm infants predisposed to sepsis. Recently, hematopoietic colony-stimulating factors have been demonstrated to improve in vitro neonatal neutrophil physiologic activity. Future therapy of neonatal sepsis will depend on new nontoxic methods for enhancing neonatal host defense.

A number of viruses cause acute central nervous system disease. The two major clinical presentations are aseptic meningitis and the less common meningoencephalitis. Clinical virology laboratories are now more widely available than a decade ago; they can be operated on a modest scale and can be tailored to the needs of the patients they serve. Most laboratories can provide diagnostic information on diseases caused by enteroviruses, herpesviruses, and human immunodeficiency virus. Antiviral therapy for herpes simplex virus is now available. By providing a rapid diagnostic test or isolation of the virus or both, the virology laboratory plays a direct role in guiding antiviral therapy for patients with herpes simplex encephalitis. Although there is no specific drug available for enteroviruses, attention needs to be paid to these viruses since they are the most common cause of nonbacterial meningitis and the most common pathogens causing hospitalization for suspected sepsis in young infants in the United States during the warm months of the year. When the virology laboratory maximizes the speed of viral detection or isolation, it can make a significant impact on management of these patients. Early viral diagnosis benefits patients with enteroviral meningitis, most of whom are hospitalized and treated for bacterial sepsis or meningitis or both; these patients have the advantage of early withdrawal of antibiotics and intravenous therapy, early hospital discharge, and avoidance of the risks and costs of unnecessary tests and treatment. Enteroviral infection in young infants also is a risk factor for possible long-term sequelae. For compromised patients, the diagnostic information helps in selecting specific immunoglobulin therapy. Good communication between the physician and the laboratory will result in the most benefit to patients with central nervous system viral infection.
