The physiological immunodeficiency of preterm and term newborns is the major cause of their increased susceptibility to infections. Although nonspecific and specific host defence mechanisms are morphologically intact, there are functional and quantitative defects. Supportive immunotherapy is required to equalize these immunological defects. This article reviews topical possibilities for immunotherapy of neonatal sepsis (exchange transfusion, transfusion of fresh blood or fresh plasma, granulocyte transfusion, use of immunoglobulins, fibronectin, interferon and colony-stimulating factor).

During the past two decades, an explosive growth in both the prevalence and types of sexually transmitted diseases has occurred. Up to 55 percent of homosexual men with anorectal complaints have gonorrhea; 80 percent of the patients with syphilis are homosexuals. Chlamydia is found in 15 percent of asymptomatic homosexual men, and up to one third of homosexuals have active anorectal herpes simplex virus. In addition, a host of parasites, bacterial, viral, and protozoan are all rampant in the homosexual population. Furthermore, the global epidemic of AIDS has produced a plethora of colorectal manifestations. Acute cytomegalovirus ileocolitis is the most common indication for emergency abdominal surgery in the homosexual AIDS population. Along with cryptosporidia and isospora, the patient may present to the colorectal surgeon with bloody diarrhea and weight loss before the diagnosis of human immunodeficiency virus (HIV) disease. Other patients may present with colorectal Kaposi's sarcoma or anorectal lymphoma, and consequently will be found to have seropositivity for HIV. However, in addition to these protean manifestations, one third of patients with AIDS consult the colorectal surgeon with either condylomata acuminata, anorectal sepsis, or proctitis before the diagnosis of HIV disease. Although aggressive anorectal surgery is associated with reasonable surgical results in some asymptomatic HIV positive patients, the same procedures in AIDS (symptomatic HIV positive) patients will often be met with disastrous results. It is incumbent upon the surgeon, therefore, to recognize the manifestations of HIV disease and diagnose these conditions accordingly.

Thirty-nine patients with adult respiratory distress syndrome (ARDS) were enrolled in a study to identify potential age-related changes in organ system function that may help explain the apparent association between age and poor outcome in these patients. Criteria for enrollment included an arterial PO2-to-inspired O2 concentration ratio less than or equal to 200 in a clinical setting consistent with ARDS. Patients were excluded if they were less than 18 yr old, had clinical manifestations of congestive heart failure, were seropositive for the human immunodeficiency virus, or had stage II metastatic lung cancer. Patients were divided into two groups: those less than 60 yr old (mean 42 +/- 3 yr, n = 17) and those greater than or equal to 60 yr old (73 +/- 2 yr, n = 16). A group of six patients was analyzed as a separate subset based on a body temperature less than or equal to 97.5 degrees F at enrollment (hypothermic patients, 73 +/- 4 yr old). Sepsis was present in 67% of the nonhypothermic patients and in all the hypothermic patients. Mortality rates were 12% in the patients less than 60 yr and 69% in the nonhypothermic patients greater than or equal to 60 yr. All the hypothermic patients died. Sequential data obtained over 6 days were compared within and between groups. The following results were obtained. 1) The ratio of arterial PO2 to inspired O2 fraction was greater and the positive end-expiratory pressure used was significantly less in the patients greater than or equal to 60 yr old compared with the younger group.(ABSTRACT TRUNCATED AT 250 WORDS)

Adverse effects are common in patients with acquired immunodeficiency syndrome (AIDS) who receive trimethoprim-sulfamethoxazole (TMP-SMX). Two patients experienced a rare anaphylactoid syndrome. Within hours of receiving a double-strength TMP-SMX tablet, a 28-year-old human immunodeficiency virus (HIV)-positive man developed fever, hypotension, and bilateral pulmonary infiltrates. Broad-spectrum antimicrobial therapy was begun but discontinued 2 days later when signs and symptoms resolved and specimens for Pneumocystis carinii were negative. A 38-year-old man developed rash, fever, hypotension, hyperbilirubinemia, renal dysfunction, and bilateral pulmonary infiltrates after taking two doses of oral TMP-SMX. Several antimicrobial agents, including parenteral pentamidine, were administered despite lack of evidence for P. carinii or other infection. four case reports of similar reactions in patients with AIDS have been published. Notable differences exist between the syndrome described and anaphylaxis. The TMP-SMX anaphylactoid reactions in patients with AIDS mimic sepsis or opportunistic infection, thus making diagnosis difficult.

To assess the effect of the human immunodeficiency virus (HIV) on mortality in US women 15 to 44 years of age and to identify associated causes of death, we examined final (1980 through 1987) and provisional (1988) national mortality statistics. Between 1985 and 1988, the death rate for HIV/acquired immunodeficiency syndrome (AIDS) quadrupled (0.6 per 100,000 to 2.5 per 100,000), and by 1987, HIV/AIDS had become one of the 10 leading causes of death. In 1988, the death rate for black women (10.3 per 100,000) was nine times the rate for white women (1.2 per 100,000). The majority of deaths in both black and white women occurred in women 25 to 34 years of age, for whom HIV-related deaths accounted for 11% and 3% of all deaths in 1988, respectively. Among 1157 death certificates that included any mention of HIV/AIDS in 1987, other leading diagnoses included drug abuse (27%), Pneumocystis carinii pneumonia (20%), other pneumonias (14%), septicemia (10%), other infections not in the AIDS surveillance definition (7%), nephritis (6%), liver diseases (4%), and anemias (4%). If current mortality trends continue, HIV/AIDS can be expected to become one of the five leading causes of death by 1991 in women of reproductive age. Because women infected with HIV are the major source of infection for infants, these trends in AIDS mortality in women forecast the impact of HIV on mortality in children as well.

Recurrent nontyphoid salmonella septicemia is one of the opportunistic infections characteristic of AIDS. The increased incidence of severe salmonellosis in immunocompromised patients is due, in part, to defective cellular immunity. The literature contains reports of nine cases of extraintestinal Salmonella arizonae infections in patients ingesting rattlesnake capsules, all of whom had known underlying medical illnesses. We describe a previously healthy Hispanic man who developed S. arizonae bacteremia as his initial manifestation of infection with the human immunodeficiency virus (HIV). The patient ultimately stated that he had consumed rattlesnake meat for medicinal purposes--a relatively common practice among Hispanics. S. arizonae was cultured from the powder of all capsules remaining in his possession. To our knowledge, this represents the first reported case of S. arizonae bacteremia as the presenting manifestation of HIV infection following the ingestion of capsules containing rattlesnake meat.

We have studied the outcome of 140 general surgical procedures in 112 patients known or suspected to be infected with human immunodeficiency virus (HIV) or hepatitis B virus. Forty patients had antibodies to HIV. A wide range of surgical procedures was performed, with an overall complication rate of 5.7%. Wound infection, wound haematoma and one unexplained pyrexia were the only complications seen. Some anorectal wounds in patients with HIV antibodies were noted to heal extremely slowly, but the aggressive anorectal sepsis reported by others was not seen. The postoperative course after general surgical procedures was unremarkable in patients with HIV antibodies, and in those suspected of HIV infection, but because anorectal wounds were found to heal slowly, we recommend that anorectal surgery be conservative in patients with HIV antibodies.

One thousand and ninety human immunodeficiency virus (HIV)-positive homosexual or bisexual males were seen in one hospital for management of HIV disease over a 9-year period. One hundred and fifty-five patients were referred by acquired immunodeficiency syndrome (AIDS) physicians for general surgical management. The most frequent reason for surgical referral (64 patients) was anorectal disease which occurred in 5.9 per cent of all HIV-positive patients. One or more diagnoses were reached in 61 of the 64 patients referred with anorectal disease: warts (38 per cent of diagnoses), anorectal ulceration (26 per cent), perianal sepsis (15 per cent), neoplasia (14 per cent) and haemorrhoidal disease (8 per cent). Anorectal symptoms were relieved in 68 per cent of patients and the median survival of those treated was 17.5 months from the time of surgical referral. Both warts and perianal sepsis were associated with in situ neoplasia, but no case of progression from in situ to invasive anal squamous carcinoma was detected. The aetiology of anorectal ulcers was not clear, but surgical excision of anal ulcers and skin tags can produce healing. Palliation of anorectal symptoms in HIV-positive homosexual patients is possible but some conditions are unusual and surgeons should be familiar with their presentation and management.

Two hundred and sixty-two patients (actual number 162) of hematological malignancies were admitted to our department from November 1977 to December 1986. Fourty-three of them (16.4%) were demonstrated to be accompanied with sepsis by blood culture. In acute non-lymphocytic leukemias (AML, APL, AMoL) the rate of sepsis was 33.8% (27 patients), while in lymphocytic malignancies (ML, HD, ATL) it was 11.7% (16 patients), particularly being 3.0% in ATL. Among the detected pathogenic microorganisms, gram-negative bacilli were 86.2% in the former and 50.0% in the latter. Especially, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli occupied 58.6% of the total in the former. Laboratory examination, when sepsis occurred, revealed peripheral neutropenia in acute non-lymphocytic leukemias (mean 831/cmm) but not in lymphocytic malignancy (mean 4,420/cmm). And 20 of the 27 cases showed remarkable neutropenia of below 500/cmm in the former. On the other hand in the latter, out of 16 only one with ATL was the case. Hypogammaglobulinemia was one of the characteristic features in lymphocytic malignancies but not in acute non-lymphocytic leukemias. Hypogammaglobulinemia in lymphocytic malignancies might be affected by long-term immunodepressant therapy. Immunologic skin reaction was demonstrated to be decreased in lymphocytic malignancies on admission. From the findings mentioned above, affecting factors to infections may be mainly neutropenia in acute non-lymphocytic leukemias and immunodeficiency in lymphocytic malignancies. And sepsis can occur frequently under neutropenic condition. In ATL both of humoral- and cellular-immunologic disturbance were detected before therapy. But peripheral neutrophil count was maintained to be normal and this could be the reason for the low septic incidence in ATL despite of total immunodepression.

Effect of gamma globulin preparations on opsonic activity in whole blood from non-immunodeficiency was studied using chemiluminescence as the parameter of phagocytic function of granulocytes. Poly (ethylene) glycol treated, Fc-intact preparation clearly enhanced chemiluminescence (luminol-dependent) of blood cells phagocytosing zymosan, Escherichia coli (E. coli), or Pseudomonas aeruginosa (P. aeruginosa), but pepsin-treated preparation showed no effect. Whole blood added with intact preparation at the final concentration of 4 mg/ml showed enhanced CL induced by E. coli and P. aeruginosa in many individuals, especially in infancy, although in adult age suppressive effect was often observed. In six patients with pediatric malignancy and three newborns with suspected septicemia, CL induced by E. coli or P. aeruginosa was measured after the administration of 150 mg/kg of intact preparations, and 4/6 of malignancy showed increased CL by E. coli, and all infants showed increased CL by E. coli and P. aeruginosa. These results suggest that intact gamma globulin preparation can increase phagocytic ability of whole blood in non-immunodeficiency via its opsonins, and may justify the administration of intact gamma globulins in non-immunodeficiency for the purpose of treating bacterial infections in some selected cases.
