Activity of arildone with or without interferon against acute hemorrhagic conjunctivitis viruses in cell culture.

Arildone (WIN 38020; 4-[6-(2-chloro-4-methoxyphenoxy)hexyl]-3,5-heptanedione) inhibited the infectivity of acute hemorrhagic conjunctivitis viruses in tissue culture. Arildone did not inhibit interferon (IFN) production or IFN activity. Treatment of cultures with combinations of arildone and IFN resulted in an additive inhibition of acute hemorrhagic conjunctivitis virus production.

Oligonucleotide fingerprint analysis of enterovirus 70 isolates from the 1980 to 1981 pandemic of acute hemorrhagic conjunctivitis: evidence for a close genetic relationship among Asian and American strains.

Enterovirus 70 isolates obtained in Asia and the Americas between 1980 and 1981 from cases of acute hemorrhagic conjunctivitis were found to be very closely related by RNase T1 oligonucleotide fingerprinting. Two closely related isolates from the first acute hemorrhagic conjunctivitis epidemic (1969 to 1972) differed by many oligonucleotides from the 1980 to 1981 pandemic strains. The strong similarities of oligonucleotide patterns of isolates from the same epidemic but from distant regions of the world suggest that the genome of enterovirus 70 tends to be conserved during natural infection, a possible consequence of the transient nature of the disease.

Comparison of enzyme immunoassay and culture for diagnosis of chlamydial conjunctivitis and respiratory infections in infants.

The efficacy of Chlamydiazyme (Abbott Laboratories, North Chicago, Ill.) in detecting neonatal conjunctival and respiratory infections caused by Chlamydia trachomatis was determined by comparison of this enzyme immunoassay (EIA) with the method of isolation of chlamydiae in tissue culture. The sensitivity and specificity of Chlamydiazyme for detecting C. trachomatis in conjunctival specimens from infants with conjunctivitis were 98 and 94%, respectively. For nasopharyngeal infection in infants with conjunctivitis, the sensitivity and specificity were 87 and 92%, respectively. There were nine nasopharyngeal specimens that were Chlamydiazyme positive and culture negative. All of these specimens demonstrated the presence of typical fluorescing chlamydial elementary bodies when pellets of the original specimens were examined with a fluorescein-conjugated monoclonal antibody. When the EIA was performed on nasopharyngeal specimens from infants with suspected chlamydial pneumonia, 6 culture-positive and 10 culture-negative specimens were correctly identified.

Comparison of Kodak Surecell Chlamydia Test Kit with culture for the diagnosis of chlamydial conjunctivitis in infants.

The accuracy of the Surecell Chlamydia Test Kit (Kodak Clinical Products, Rochester, N.Y.) in detecting neonatal conjunctival infection caused by Chlamydia trachomatis was determined by comparison of this enzyme immunoassay with the isolation of C. trachomatis in tissue culture. Kodak Surecell is a rapid monoclonal antibody-based membrane capture enzyme immunoassay which can be processed in the office of a physician. The sensitivity and specificity compared to culture in detecting C. trachomatis in conjunctival specimens from infants with conjunctivitis were 93 and 96%, respectively. The test does not require specialized equipment or trained personnel and would be ideal for physicians who see low numbers of infants with possible chlamydial conjunctivitis in their offices.

Evaluation of a new optical immunoassay for diagnosis of neonatal chlamydial conjunctivitis.

The BioStar OIA Chlamydia test (BioStar, Inc., Boulder, Colo.) is a novel immunoassay system that uses changes in reflection of light to directly detect chlamydial antigen in clinical specimens. We compared the optical immunoassay (OIA) with culture for detecting Chlamydia trachomatis in ocular specimens from infants with suspected chlamydial conjunctivitis. We initially performed a retrospective evaluation, testing 152 ocular specimens previously collected for culture with the OIA. The sensitivity and specificity were 94.2 and 97%, respectively. A subsequent prospective study evaluating 37 ocular specimens from infants with suspected C. trachomatis conjunctivitis revealed a sensitivity and specificity of 100 and 92.6%, respectively.

New genome type of adenovirus serotype 4 caused nosocomial infections associated with epidemic conjunctivitis in Japan.

Human adenovirus type 4 is one of the major serotypes isolated from patients with adenoviral conjunctivitis. In 2001 we encountered nosocomial infections with epidemic conjunctivitis in the ophthalmology ward of one hospital in Sapporo, which is in the northern part of Japan. Adenoviruses were isolated from the patients with this nosocomial infection and identified as adenovirus type 4 (AdV-4) by a neutralization test with serotype-specific antiserum. When the cleavage patterns of the isolates were compared with the full viral genome with BamHI and SmaI, the cleavage patterns of the isolates were shown to be different from those of AdV-4p and other previously known AdV-4 variants. The nucleotide sequences of the fiber gene of the isolates showed the highest homologies (94.3%) with AdV-4 among the nucleotide sequences available from GenBank and formed a monophyletic cluster along with the prototype strain of AdV-4. The isolates, however, were located in a different lineage from those of AdV-4p and the AdV-4 variant from the sporadic infections. We conclude that the nosocomial infection that appeared in 2001 was caused by a new genome type of AdV-4, which was designated AdV-4c.

Conjunctivitis due to adenovirus type 19.

An outbreak of unusual conjunctivitis occurred in Seattle in the summer of 1974. We found evidence of adenovirus type 19 (Ad19) infection in 28 of 42 (67%) referred cases from whom specimens for virus isolation and/or serology were obtained. Virus was isolated from conjunctiva, throats, and/or stools, often in week 2 of illness. Ad19-related cases more frequently had severe ocular pathology, transient visual impairment, and active disease for longer than a week. Secondary illnesses were more frequent in relation to Ad19 infection (26%) than to conjunctivitis of other etiology (5%, P less than 0.05). Persons with Ad19 infection commonly experienced sore throats without coughs or fevers. No common source of infection was identified in the outbreak, and illness was unrelated to occupation, residence, or family characteristics. A 3- to 8-day incubation period was suggested by two related cases.

Clostridium pseudotetanicum bacteremia in a patient with Pasteurella multocida conjunctivitis.

Clostridium pseudotetanicum only once previously has been identified as causing disease. Pasteurella multocida has been identified only three times as the cause of purulent conjunctivitis. A very debilitated patient had C. pseudotetanicum bacteremia and P. multocida conjunctivitis from which she recovered only to die of a nosocomial Staphylococcus epidermidis septicemia, originating in a site for the administration of intravenous fluids.

Epidemic keratoconjunctivitis and chronic papillary conjunctivitis in London due to adenovirus type 19.

Since July 1973 cases of keratoconjunctivitis resembling epidemic keratoconjunctivitis were observed in the External Eye Disease Clinic at Moorfields Eye Hospital; City Road, London. Adenovirus type 19 was isolated in human embryonic kidney cells from 21 patients. The majority were males between 20 and 40 years old. A small hospital outbreak involving six patients occurred. Clinical features of the disease, consisting of moderate to severe follicular conjunctivitis, major subepithelial punctate keratitis, sometimes with pseudomembrane and scarring, were closely similar to those of epidemic keratoconjunctivitis caused by adenovirus type 8. This similarity, as well as the ability of the agent to cause hospital outbreaks, indicates that adenovirus type 19 is a cause of epidemic keratoconjunctivitis. A case of bilateral chronic papillary conjunctivitis that persisted for 16 months following an acute onset was described. Adeno 19 was isolated from the eye of the patient after 12 months of recrudescent or recurrent illness. Chronic adenovirus infection lacking the usual clinical picture of an acute follicular reaction has not hitherto been described. Such cases are probably important because of the obvious danger of continuing the carriage and shedding of infective adeno 19 from one outbreak to another, by presenting subsequently in eye clinics, and providing an unrecognised source of infection to initiate further outbreaks of hospital transmission.

Development of chronic conjunctivitis with scarring and pannus, resembling trachoma, in guinea-pigs.

Guinea-pigs were repeatedly infected with guinea-pig inclusion conjunctivitis agent. Reinfection caused severe conjunctival inflammation, and repeated reinfection led to chronic inflammation lasting for many months. This was followed by the development of pannus, follicles on the palpebral conjunctivae, scarring of the lower palpebral conjunctiva, and deformities of the lower lid. Reinfection was accompanied by small numbers of inclusion-bearing cells, small numbers of polymorphonuclear cells, and high numbers of mononuclear cells. There was no increase in the level of serum antibodies. The chronic conjunctivitis was associated with high numbers of mononuclear cells and no inclusions or polymorphonuclear cells. The response to reinfection appears to be a delayed-type hypersensitivity reaction, and we suggest that the chronic inflammation, pannus, scarring, and lid deformities associated with hyperendemic trachoma may be due to repeated reinfection combined with delayed-type hypersensitivity.

Efficacy of antiprostaglandin therapy in vernal conjunctivitis.

Twenty-seven patients with vernal conjunctivitis who remained symptomatic following treatment with corticosteroid drops and/or Opticrom drops (sodium cromoglycate 2%, benzalkonium chloride 0.01%) were treated with aspirin. Aspirin produced marked improvement in all patients apart from three. The possible mechanism of the efficacy of aspirin in vernal conjunctivitis is discussed.

Economic aspects of an epidemic of haemorrhagic conjunctivitis in a rural community.

The estimated economic loss due to an epidemic of acute haemorrhagic conjunctivitis in 1981 in a rural community of Goa studied by house-to-house survey of 7230 families is reported. Thirty-five per cent of families were affected and in 62% of these families more than three persons developed conjunctivitis. The affected were forced to be absent from work resulting in a reduction of the work force (loss of 7735 man days) and loss of income (Rs 1,33,300). The type of treatment followed and estimates of treatment cost are described. The economic consequences to the country of this widespread epidemic are described.

Pharmacokinetics of enrofloxacin and its efficacy in comparison with doxycycline in the treatment of Chlamydophila felis infection in cats with conjunctivitis.

The concentrations of enrofloxacin were measured in the tears, saliva and serum of 14 cats with signs of upper respiratory tract infection and eight with no signs, after daily doses of 5 mg/kg. Enrofloxacin concentrations above the minimum inhibitory concentration of Chlamydophila felis were found in the saliva and tears of the cats with and without signs of upper respiratory tract infection. In a prospective randomised clinical trial, the efficacy of enrofloxacin against C. felis infection in cats with conjunctivitis was compared with the efficacy of doxycycline. Twenty-five cats were randomly assigned to treatment with either enrofloxacin or doxycycline for 14 days; 15 of the cats tested positive for C. felis by an immunofluorescent antibody test on conjunctival swabs. The two treatment groups showed equal improvements in the clinical signs of conjunctivitis and C. felis infection status; in each group three cats were still C. felis antigen-positive after the 14-day course of treatment, indicating a persistent infection. No side effects were observed in the cats treated with enrofloxacin.

Topical lomefloxacin 0.3% twice daily versus tobramycin 0.3% in acute bacterial conjunctivitis: A multicenter double-blind phase III study.

AIMS/BACKGROUND: To evaluate in a double-masked comparative, prospective, randomized multicenter trial the efficacy of lomefloxacin 0.3% eye drops twice daily and of tobramycin eye drops 4 times daily in patients with acute bacterial conjunctivitis. METHODS: Ninety-nine subjects were enrolled: 50 were treated with lomefloxacin 0.3% eye drops twice daily and 49 with tobramycin 0.3% eye drops 4 times daily. In all patients, conjunctival swabbing and assessment of objective signs and of subjective symptoms were performed. RESULTS: There was no statistical difference for any individual sign or symptom or for the sum score of either key or other signs and symptoms at any of the examination days. The sum score of both key and other signs and symptoms decreased in both groups at day 3-4 as compared to baseline values (p < 0.0001). The decrease in both these scores continued significantly from day 3-4 to day 7-8 (p < 0.05) and was similar in the two treatment groups (p > 0.4). The lowest resistance rate was seen in lomefloxacin (3.5%) and in neomycin (7.0%), while tobramycin showed resistance in 10 out of 88 resistance strains (11.4%). CONCLUSION: Both lomefloxacin 0.3% twice daily and tobramycin 0.3% administered 4 times daily were well tolerated and showed a high degree of clinical and microbiological efficacy in the treatment of acute bacterial conjunctivitis. Lomefloxacin caused less resistance than other antibiotics evaluated.

Papillary conjunctivitis induced by an epithelialized corneal foreign body.

This report of papillary conjunctivitis induced by a corneal foreign body suggests that papillogenesis may result from physical/mechanical tissue trauma. A case is presented with an epithelialized corneal foreign body in the peripheral cornea during a 9-month period. The overlying corneal epithelial surface was elevated, and corresponding upper tarsal conjunctiva revealed localized, elevated papillae. One month after the foreign body was excised, the papillae resolved. An epithelialized foreign body, elevated cornea, and coincidental papillae support the role of physical trauma for the development of papillae--a feature of the syndrome of contact-lens-associated giant papillary conjunctivitis.

Conjunctival provocation tests in suspected allergic conjunctivitis: a clinical study.

We examined 57 patients who showed conjunctivitis suspected of allergic pathogenesis with skin radioallergosorbent (RAST) and conjunctival provocation tests (CPT). Our aim was to define statistical correlations between those tests and their exact values for the right diagnosis. Our data show that CPT is more sensitive than skin tests or RAST to ascertain the origin of conjunctivitis.

Cytological evaluation of adenoviral follicular conjunctivitis by cytobrush.

Conjunctival brush samples from 38 patients with acute conjunctivitis were examined to determine whether cellular features could be utilized for cytodiagnosis. Of all cases, 32 (84%) patients showed a characteristic cell pattern for adenoviral follicular conjunctivitis (AFC) and in the remaining 6 (16%) patients herpetic infection was suggested cytologically. The background of the conjunctival smears from patients with AFC was characterized by the predominance of lymphocytes with little fibrinous discharge. In addition, two types of nuclear alterations were demonstrated i.e. intranuclear inclusions and a so-called ground-glass nuclear appearance. Ground-glass nuclei occurred more frequently than intranuclear inclusions in patients with AFC. However, the presence of lymphocytes in conjunctival smears was a useful criterion for making the differential diagnosis between herpetic and adenoviral infections. Thus, in the absence of these three cellular changes, i.e. ground-glass nuclei, intranuclear inclusions and lymphocytic background, infectious conditions other than AFC may be considered, regardless of the numbers of conjunctival cells present. Emphasis is placed on the value of conjunctival brush cytology for the rapid diagnosis of cases of suspected AFC.
