Griseofulvin administration was associated with the development of absolute neutropenia in six of seven (86%) cats with feline immunodeficiency virus (FIV) infection. The neutropenia was severe (less than 400 neutrophils/microliter) in four of the six affected cats, and one cat died from sepsis. Neutrophil counts returned to baseline values within 15 days after drug withdrawal in all surviving cats. No symptoms or hematologic abnormalities were observed in four normal (FIV-seronegative) cats treated with the same lot of griseofulvin at equivalent doses. Neutropenia recurred in two of two FIV-seropositive cats upon griseofulvin rechallenge. Cats with FIV infections appear to be at increased risk for griseofulvin-associated neutropenia. This phenomenon may be analogous to the increased frequency of antibiotic-induced neutropenias observed in humans infected with the human immunodeficiency virus.

Although listeriosis is an uncommon infection in patients with human immunodeficiency virus (HIV) infection, the frequency of listeriosis in New York City has increased because of the increase in the number of HIV-infected patients. The medical records of 30 patients admitted to three medical centers in New York City from 1981 to 1988 with infections due to Listeria monocytogenes were reviewed. Six patients had AIDS, one was seropositive and asymptomatic, and four had risk factors for HIV infection. While the annual number of cases of listeriosis in patients without risk factors for HIV infection was constant, 9 of the 11 patients with AIDS or with risk factors for HIV infection presented with listeriosis between 1985 and 1988, the last half of the survey period. These patients were male homosexuals or intravenous drug abusers, and all but one were black or Hispanic. Manifestations of listeriosis in patients with AIDS or with risk factors for HIV infection included bacteremia without apparent source in seven, meningitis in three, and endocarditis in one, syndromes that were similar to those in patients without risk factors for HIV infection. Ten of 11 patients were treated with penicillin or ampicillin, and 7 were also given an aminoglycoside. All patients responded well to therapy and no relapses were observed. Physicians should include antibiotics effective against L. monocytogenes when treating AIDS patients with meningitis of unknown origin and consider the diagnosis of listeriosis in patients with sepsis of unknown origin.

The preparation, pharmacokinetics, clinical uses, dosage and administration, and adverse effects of intravenous immune globulin (IVIG) are reviewed. IVIG, which consists primarily of immunoglobulin G (IgG), is initially prepared from pooled human plasma by using the Cohn-Oncley fractionation procedure. Secondary treatments render the preparation suitable for i.v. use. The specific antibody content of IVIG depends on the geographic location of the plasma donors, the product, and the product lot. The metabolism of IgG appears to follow a multicompartmental, first-order process. The half-life of IgG is dependent on the half-lives of the IgG subclasses; three of the four subclasses have half-lives in the range of 23-25 days. IVIG is indicated in the treatment of idiopathic thrombocytopenic purpura (ITP) and as replacement therapy in primary humoral immunodeficiencies (PHI). IVIG has also been used for antimicrobial prophylaxis in bone marrow transplant and burn patients and in patients with malignancies. Patients with HIV infection, cystic fibrosis, neonatal sepsis, and respiratory syncytial virus infection may also benefit from prophylaxis or treatment with IVIG. The recommended dosage of IVIG in ITP is 400 mg/kg/day for two to five days. For the treatment of PHI, the usual dosage is 100-400 mg/kg every three or four weeks. Adverse reactions are often mild and are usually related to the infusion rate. Intravenous immune globulin is a valuable therapeutic tool in several immunodeficiency and autoimmune states, but IVIG products are expensive, and conclusive data on their efficacy in the treatment of many disorders remain to be obtained.

The experience of surgeons in Africa with patients infected with human immunodeficiency virus (HIV) suggests 5 trends: 1) an increased incidence of surgical sepsis--most commonly in the female genital tract, the pleural cavity, large joints, and the anorectal area--in HIV-infected patients; 2) an increase in surgical tuberculosis of spine, bone joints, lymph nodes, and the peritoneal cavity concomitant with an increased incidence of pulmonary tuberculosis in high-incidence countries; 3) impaired healing of wounds, wound breakdown, and the development of skin lesions and ulcers; 4) tumors whose aggressiveness is accelerated by HIV infection; and 5) new pathologies such as nonspecific cystitis, chronic osteitis, and vascular disease. In many cases, HIV infection has not been identified until after hospital patients have demonstrated a rapid, progressive decline after routine surgery. To date, only 1 study has attempted to determine the extent to which HIV infection influences the outcome of surgery. Mortality in an intensive care unit at the University Teaching Hospital in Lusaka, Zambia, differed significantly between HIV-positive and seronegative patients only in terms of pneumonia; however, seropositive patients also have an elevated, albeit nonsignificant, risk of mortality from severe gynecologic sepsis.

The characteristics of the natural history of acute sepsis and the nature of the intoxication syndrome are analysed an on ample material (120 patients), and microbiological and immunological diagnostic findings are shown. Endotoxicosis in sepsis is attended by marked disorders of the immune status in the form of varying degrees of immunodeficiency. The authors generalize their experience with the management of endotoxicosis in sepsis. The article first shows the results of the combined use of various methods of endotoxicosis correction (homosorption, hemodiafiltration, plasmapheresis, endolymphatic therapy, ultraviolet irradiation of autoblood, hyperbaric oxygenation, application sorption) in the treatment of 120 patients with sepsis of various etiology. Active methods of detoxification via the blood and lymphatic system were first applied in the management of endotoxicosis in patients with sepsis.

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.

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.
