A spontaneously occurring antibasement membrane antibody has been further characterised according to antigenic specificity, immunoglobulin class, and tissue localisation using immunofluorescent and immunoelectron microscopic techniques. The autoantibody reacted with the basement membrane of kidney tubules, Bowman's capsule, and the epithelial portion of ileum but not with the basement membrane of skin, cornea, glomerulus, or oesophagus. It also reacted with bile canaliculi, sarcolemmal sheath, and salivary duct. On electron microscopy the antibody was distributed along the basement membrane of Bowman's capsule and renal tubules. Some reactivity against collagen was observed. Antibody activity was found in both IgG and IgM fractions. In immunodeficiency disorders, the autoantibody was found only in patients with selective IgA deficiency.

Mycobacterium gordonae is only rarely a cause of infection despite its ubiquity in the environment. We describe an 11-year-old girl with disseminated infection due to M. gordonae whose course was complicated by renal failure requiring hemodialysis but who recovered after 15 months of chemotherapy. In a literature search we identified 23 additional cases of infection attributed to M. gordonae, with involvement of the lungs (eight), soft tissue (seven), the peritoneal cavity (three), the cornea (one), and with disseminated disease (five patients, including ours). Two patients were infected with human immunodeficiency virus. We assessed the patterns of infection characteristic of each site and the antibiotic sensitivities of the isolates. Adequate documentation of M. gordonae infection (e.g., amount of growth per culture, detection of specific biochemical characteristics, and confirmation of the organism's identity by a reference center) was lacking in many reports. M. gordonae should not automatically be dismissed as a contaminant when isolated from clinical material. Additional studies are required to establish the extent of this organism's pathogenic role.

Recent reports suggest that acquired immunodeficiency syndrome (AIDS) patients are at higher risk of developing mucocutaneous reactions such as toxic epidermal necrolysis and Stevens-Johnson syndrome (SJS). Resultant dry eye may be further exacerbated by human immunodeficiency virus (HIV) related lacrimal gland dysfunction and lead to a chronic keratoconjunctivitis. We report one patient with AIDS and toxic epidermal necrolysis and two patients with AIDS and SJS who developed severe dry eye misdiagnosed as infectious keratoconjunctivitis. Cicatrizing mucocutaneous reactions should be suspected in AIDS patients and the dry eye treated to control symptoms and prevent complications.

Contact lens (CL) fitting carries the risk of transmitting infectious agents, including adenovirus and Pseudomonas. Therefore, a number of precautions must be observed to ensure safety in the office. Paramount among these is hand washing, both immediately after contact with a patient's eyes and again between patients. Equally important is that all trial lenses and CLs removed from patients be disinfected before reuse. Low-water-content soft CLs can be heat disinfected; high-water-content CLs require chemical treatment. A combination of surfactant cleaning with a chlorhexidine-containing agent and hydrogen peroxide disinfection is preferred for rigid lenses to guarantee destruction of human immunodeficiency virus (HIV). The proper use of lens care solutions is also necessary to minimize the risk of their becoming contaminated with pathogenic organisms. Only commercially prepared solutions should be used, preferably in small-volume bottles that are frequently replaced. Preservative-free solutions should be discarded after 1 day's use, whereas preserved solutions may be used for up to 2 weeks. Sterile saline rather than tap water is recommended for rinsing rigid lenses. Finally, part of the clinician's responsibility in running a safe office is to educate patients about these hygienic practices.

We retrospectively examined Michigan Eye-Bank and Transplantation Center data on all eye/cornea donors in Michigan and Illinois for whom human immunodeficiency virus (HIV) antibody screening results were available. This was done to compare the HIV-antibody positive serology rate in hospital versus medical examiner donors. This population consisted of 3,783 donor records for the period January 1, 1986 through June 30, 1988--a 30-month period. Of these, 2,628 records were from hospital donors, and 1,155 were medical examiner cases. Of the 2,628 hospital donors, 22 (or 0.83%) tested positive for HIV antibody. Ten of the 1,155 medical examiner donors (or 0.87%) tested positive for HIV antibody. We examined donor demographics of gender, race, age, positive hepatitis B surface antigen, and residence for each group. The difference in the HIV antibody-positive rate between the two groups--hospital and medical examiner donors--is 0.04%, with a slightly higher rate in the medical examiner group. The chi-square was 0.0079, and the p-value was 0.928. We conclude that this difference is neither clinically nor statistically significant.

Human immunodeficiency virus (HIV) was recovered from multiple ocular tissues in three patients with acquired immune deficiency syndrome (AIDS). Consistently found in the retina, HIV was also detected in the conjunctiva, cornea, and iris. In two cases, HIV was detectable despite treatment with oral zidovudine. All three patients had bilateral cytomegalovirus (CMV) retinitis managed by intravitreal injection of ganciclovir. Culture of the retina for CMV was negative in all three cases. The finding of HIV in multiple ocular tissues is consistent with the neurotropic nature of the virus, and may explain some of the common ocular manifestations of AIDS such as AIDS retinopathy. Infection with HIV may predispose the retina to other opportunistic infections and may explain the high incidence of CMV retinitis in AIDS patients. This is the first report of HIV isolation from tissue within the eye.

Using a simple mathematical model, we calculated the risk for a patient undergoing penetrating keratoplasty to receive a cornea from a human immunodeficiency virus-infected donor despite negative results on serologic testing of donor serum. This error in serologic testing occurred when false-negative results were obtained from the enzyme-linked immunosorbent assay used to screen donor corneas for human immunodeficiency virus exposure. The average risk of transplanting an infected cornea was low, 0.03%, but increased by a factor of ten when donor tissue from donors at high risk for AIDS was used. Current screening procedures are probably adequate to prevent transmission of human immunodeficiency virus, but increased vigilance for high-risk donor populations may be appropriate.

Over a period of 14 months (from October 1985 to December 1986) 152 potential cornea donors were evaluated for human immunodeficiency virus (HIV) and hepatitis B surface (HBs) antigen. In three clinically normal donors (two deaths due to natural causes, one as a result of an automobile accident), HIV seroconversion was found by ELISA techniques in two cases and a positive Western Blot test in one. The two elderly patients had previously undergone multiple blood transfusions during major abdominal surgery in smaller community hospitals before blood donors were routinely tested for HIV; one 20-year-old patient was probably a homosexual, as in-depth interviews with his family doctor revealed. Hepatitis B serology was positive in four potential cornea donors. The authors conclude that interdisciplinary work-ups of potential cornea donors should include screening for infectious diseases.

Forty eye banks responded to an Eye Bank Association of America (EBAA) questionnaire concerning screening patients at risk for acquired immune deficiency syndrome (AIDS) and hepatitis B. Respondents accounted for 26% (8787 of 33,500) of the total volume of eyes donated in North America in 1986. Sixty (0.68%) of 8787 donors were found to be antibody positive for human immunodeficiency virus (HIV) and 69 (1.33%) of 5187 donors were found to be positive for hepatitis B virus (HBV). The age, cause of death, and source of tissue were also studied. The finding of seropositivity for HIV in very young and elderly donors without identified risk factors underscores the need to screen all potential cornea donors for the presence of HIV antibodies. The data on HBV lend further support to the importance of such screening procedures.

Four corneas from two cadavers that later had positive test results on enzyme-linked immunosorbent assays and Western blot analysis for antibodies against the human immunodeficiency virus were inadvertently transplanted to recipients who were without known risk of human immunodeficiency virus infection. We performed serial studies of serologic markers of human immunodeficiency virus infection in the cornea recipients and assayed reverse transcriptase levels of their mixed lymphocyte cultures. The four cornea transplant recipients were followed up for 130, 152, 397, and 440 days, respectively, and the results on all serologic tests and reverse transcriptase assays remain negative.
