Inflammatory reactions in HIV-1-infected persons after initiation of highly active antiretroviral therapy.

PURPOSE: To review reported inflammatory reactions occurring after initiation of highly active antiretroviral therapy (HAART) in persons infected with HIV-1 and to explore the mechanisms leading to these reactions. DATA SOURCES: MEDLINE search of biomedical literature reporting inflammatory reactions after HAART. Bibliographies of retrieved reports were also reviewed. STUDY SELECTION: Articles describing patients infected with HIV-1 who had immunologic and virologic responses to HAART and subsequently developed inflammatory reactions. DATA EXTRACTION: Data on the immune status, clinical characteristics, and therapeutic management of patients who were seropositive for HIV-1 and had inflammatory reactions after HAART. DATA SYNTHESIS: Inflammatory reactions involving opportunistic infections, AIDS-associated malignant conditions, and other noninfectious diseases have recently been described in patients infected with HIV-1. These conditions often appeared shortly after the introduction of HAART and were associated with pronounced reductions in plasma HIV-1 viral load and increases in CD4(+) T-lymphocyte counts. Clinical presentation was often atypical of that in patients with untreated HIV-1 infection, probably because of restored immunity. Most cases improved despite continuation of HAART, although some patients required anti-inflammatory drugs or specific antimicrobial agents. CONCLUSIONS: Clinicians caring for patients who are infected with HIV-1 and receiving HAART must be aware of this new and diverse clinical syndrome. As more HAART recipients are studied, new presentations will probably be observed.

Herpes simplex peritonitis: case report.

It has been previously reported that the most common cause of peritonitis in patients undergoing chronic ambulatory peritoneal dialysis (CAPD) is infection by a single gram-positive bacterial species. Polymicrobial bacterial infections are identified that may be secondary to bowel perforation. In 20% of cases bacterial cultures are negative. Although cultures may be negative when infection is due to a fastidious organism, when antibiotic therapy has been administered, and in cases of chemical peritonitis, a viral etiology should also be considered. We report the first documented case of herpes simplex peritonitis, which involved a 60-year-old female undergoing CAPD. Viral peritonitis may be an important form of peritonitis that has been previously unrecognized and should be considered in the differential diagnosis.

Pyogenic vertebral osteomyelitis of the posterior elements.

Lone pyogenic involvement of the posterior elements of the vertebrae is a rare event. We present two cases of isolated lumbar vertebral infection of the posterior elements and review 13 cases previously reported in the literature. Clinical presentation, laboratory and radiographic findings, microbiological etiology, and treatment were evaluated. Back pain, an elevated erythrocyte sedimentation rate, and computed tomography or magnetic resonance imaging were most useful in identifying the presence and extent of infection. Antibiotic therapy with or without surgical intervention was successful in all cases.

Infectious complications of hepatic cryosurgery.

Hepatic cryosurgery is a novel procedure for patients with metastatic liver disease. To date, no reviews of the infectious complications of this procedure have been published. One hundred and fifty patients underwent 158 hepatic cryosurgical procedures at Allegheny General Hospital (Pittsburgh) from November 1987 through July 1995. Gastrointestinal malignancies accounted for 93% of the underlying diagnoses. The following 12 infections were directly related to the cryosurgical procedure: hepatic abscess (six), intraperitoneal abscess (three), ascending cholangitis (two), and an intrahepatic device (Infusaid; Strato/Infusoid, Norwood, MA) infection (one). Enterococcus was the most commonly isolated organism. Seven of the 12 infections were polymicrobial. The patients who developed infections had longer hospital stays (26 days vs. 13 days) and had more days of fever (6.5 days vs. 2.3 days). than those who did not develop infections. If perioperative manipulation of the biliary tree is avoided, the infection rate in patients who undergo hepatic cryosurgery may be decreased even further. Overall, cryoablation of the liver is not related to an increased risk of infection.

Patients treated by a thoracic surgeon with HIV. A review.

Transmission of HIV from healthcare worker to patient has been documented in one report. Though the means of transmission in that case remains unknown, procedures that involve exposure to blood or mucous membranes are thought to carry an increased risk. Because of previous evidence of transmission of hepatitis B by cardiothoracic surgeons, they have been identified as a group known to perform exposure-prone invasive procedures with a risk of viral transmission. A retrospective review of 612 patients of a cardiothoracic surgeon who is HIV-positive was conducted in an attempt to identify any instance of viral transmission. A total of 189 patients received HIV testing and counseling. No positive test results were obtained.

Quinolone antibacterial agents for the treatment of genitourinary tract infections.

The fluoroquinolones have expanded the therapeutic options available for the treatment of genitourinary tract infections. Their ease of oral administration, favourable pharmacokinetics, low incidence of adverse reactions, and broad spectrum of in vitro activity against aerobic and facultative organisms make them especially suitable for treating bacteriuria, particularly when pathogens are resistant to other available oral agents. Their efficacy has also been established in the treatment of prostatis, gonorrhea and chancroid. They have lower in vitro activity against chlamydia, ureaplasma and anaerobes, and their role in the treatment of non-gonococcal urethritis, vaginitis and acute pelvic inflammatory disease is less well established.

In vitro activity of DNA gyrase inhibitors, singly and in combination, against Mycobacterium avium complex.

The in vitro activities of the DNA gyrase inhibitors ciprofloxacin, coumermycin, and novobiocin against 31 clinical isolates of Mycobacterium avium complex were studied using a microdilution technique. Minimal inhibitory concentrations (MICs) were determined in 4 days using Middlebrook 7H9 broth, and minimal bactericidal concentrations (MBCs) were determined by subculturing to Middlebrook 7H10 agar. MICs were: ciprofloxacin, 0.5-greater than 16 (mean, 4.1) micrograms/ml; novobiocin, 4-greater than 128 (mean, 54.7) micrograms/ml; and coumermycin, 2-greater than 16 (mean, 17.5) micrograms/ml. MBCs were usually more than two dilution steps higher than MICs. Checkerboard studies failed to reveal synergistic or antagonistic inhibitory activity of DNA gyrase-A and DNA gyrase-B inhibitors in vitro.
