Abstract
As technology continues to evolve, the possibility for a wide range of dangers to people, organizations, and countries escalate globally. The United States federal government classifies types of threats with the capability of inflicting mass casualties and societal disruption as Chemical, Biological, Radiological, Nuclear, and Energetics/Explosives (CBRNE). Such incidents encompass accidental and intentional events ranging from weapons of mass destruction and bioterrorism to fires or spills involving hazardous or radiologic material. All of these have the capacity to inflict death or severe physical, neurological, and/or sensorial disabilities if injuries are not diagnosed and treated in a timely manner. Ophthalmic injury can provide important insight into understanding and treating patients impacted by CBRNE agents; however, improper ophthalmic management can result in suboptimal patient outcomes. This review specifically addresses the biological agents the Center for Disease Control and Prevention (CDC) deems to have the greatest capacity for bioterrorism. CBRNE biological agents, encompassing pathogens and organic toxins, are further subdivided into categories A, B, and C according to their national security threat level. In our compendium of these biological agents, we address their respective CDC category, systemic and ophthalmic manifestations, route of transmission and personal protective equipment considerations as well as pertinent vaccination and treatment guidelines.

Abstract
IMPORTANCE Fluoroquinolones are the most commonly prescribed antibiotic class in the outpatient setting. Recent reports have implicated an association between oral fluoroquinolones and an increased risk of uveitis. OBJECTIVE To determine the hazard of uveitis with oral fluoroquinolone use. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted using medical claims data from a large national US insurer (N = 4,387,651). Cohorts from ambulatory care centers across the United States were created including every new user of an oral fluoroquinolone or β-lactam antibiotic prescription with at least 24 months of data prior to the date of the prescription from January 1, 2000, to January 30, 2013. Exclusion criteria consisted of any previous diagnosis of uveitis or a uveitis-associated systemic illness. Participants were censored for a new diagnosis of a uveitis-associated systemic illness, the end of an observation period, use of the other class of antibiotic, or removal from the insurance plan. Data analysis was performed from January 2 through March 15, 2015. MAIN OUTCOMES AND MEASURES The hazard of a uveitis diagnosis after a fluoroquinolone prescription compared with a β-lactam prescription using multivariate regression with Cox proportional hazards models. RESULTS Of the 4,387,651 patients in the database, 843,854 individuals receiving a fluoroquinolone and 3,543,797 patients receiving a β-lactam were included in the analysis. After controlling for age, race, and sex using multivariate analysis, no hazard for developing uveitis at the 30-, 60-, or 90-day observation windows was seen (hazard ratio [HR] range, 0.96; 95% CI, 0.82-1.13; to 1.05; 95% CI, 0.95-1.16; P > .38 for all comparisons). The 365-day observation period showed a small increase in the HR for the fluoroquinolone cohort (1.11; 95% CI, 1.05-1.17; P < .001). Moxifloxacin produced an increased hazard for uveitis at every time point (HR range, 1.47-1.75; 95% CI, 1.27-2.37; P < .001 for all comparisons). Secondary analysis demonstrated a similar hazard at 365 days for a later diagnosis of a uveitis-associated systemic illness after fluoroquinolone use (HR range, 1.46-1.96; 95% CI, 1.42-2.07; P < .001 for all comparisons). CONCLUSIONS AND RELEVANCE These data do not support an association between oral fluoroquinolone use and uveitis. Instead, this study shows an association between oral fluoroquinolone use and the risk for uveitis-associated systemic illnesses, which is a possible source of bias that could explain the findings of previous studies.

Abstract
Reactive arthritis is associated with conjunctivitis or iritis. Rarely reactive arthritis is accompanied by permanent visual loss from macular infarction or foveal scarring. We present the case of a rheumatologist who had a sudden onset of skin lesions, arthritis of several joints and bilateral visual loss. Most of these manifestations resolved after a course of oral corticosteroids. However he was left with decreased vision in the left eye and multiple lesions in the fovea over a follow-up of 2 years.

Abstract
Objective.Spondyloarthritides (SpA) can present different disease spectra according to ethnic background. The Brazilian Registry of Spondyloarthritis (RBE) is a nationwide registry that comprises a large databank on clinical, functional, and treatment data on Brazilian patients with SpA. The aim of our study was to analyze the influence of ethnic background in SpA disease patterns in a large series of Brazilian patients.Methods.A common protocol of investigation was prospectively applied to 1318 SpA patients in 29 centers distributed through the main geographical regions in Brazil. The group comprised whites (65%), African Brazilians (31.3%), and people of mixed origins (3.7%). Clinical and demographic variables and various disease index scores were compiled. Ankylosing spondylitis (AS) was the most frequent disease in the group (65.1%); others were psoriatic arthritis (18.3%), undifferentiated SpA (6.8%), enteropathic arthritis (3.7%), and reactive arthritis (3.4%).Results.White patients were significantly associated with psoriasis (p = 0.002), positive HLA-B27 (p = 0.014), and use of corticosteroids (p < 0.0001). Hip involvement (p = 0.02), axial inflammatory pain (p = 0.04), and radiographic sacroiliitis (p = 0.025) were associated with African Brazilian descent. Sex distribution, family history, and presence of peripheral arthritis, uveitis, dactylitis, urethritis, and inflammatory bowel disease were similar in the 3 groups, as well as age at disease onset, time from first symptom until diagnosis, and use of anti-tumor necrosis factor-α agents (p > 0.05). Schober test and thoracic expansion were similar in the 3 groups, whereas African Brazilians had higher Maastricht Ankylosing Spondylitis Enthesitis Scores (p = 0.005) and decreased lateral lumbar flexion (p = 0.003), while whites had a higher occiput-to-wall distance (p = 0.02). African Brazilians reported a worse patient global assessment of disease (p = 0.011). Other index scores and prevalence of work incapacity were similar in the 3 groups, although African Brazilians had worse performance in the Ankylosing Spondylitis Quality of Life questionnaire (p < 0.001).Conclusion.Ethnic background is associated with distinct clinical aspects of SpA in Brazilian patients. African Brazilian patients with SpA have a poorer quality of life and report worse disease compared to whites.

Abstract
PURPOSE NOD1 plays an important role in host defense and recognizes the minimal component of bacterial cell walls, meso-diaminopimelic acid (iE-DAP). Polymorphisms in NOD1 are associated with autoinflammatory diseases characterized by uveitis such as Crohn's disease and sarcoidosis. NOD1 is homologous to NOD2, which is responsible for an autosomal dominant form of uveitis. Nonetheless, the role of NOD1 in intraocular inflammation has not been explored. The induction of uveitis by iE-DAP in mice and the potential contribution of interleukin (IL)-1beta were investigated. METHODS BALB/c mice or mice deficient in caspase-1 or IL-1R1 and their congenic controls were injected intravitreally with iE-DAP or saline. The time course, dose response, and contribution of IL-1beta to ocular inflammation were quantified by intravital video microscopy, histology, and immunohistochemistry. NOD1 and IL-1beta were measured in eye tissue by immunoblotting and ELISA. RESULTS NOD1 protein is expressed in the eye and promotes ocular inflammation in a dose- and time-dependent fashion. The authors previously defined the role of IL-1beta in NOD2 uveitis and tested whether NOD1 and NOD2 used similar mechanisms. Treatment with iE-DAP significantly increased IL-1beta, which was caspase-1 dependent. However, in contrast to NOD2, caspase-1 and IL-1R1 were essential mediators of iE-DAP-induced uveitis, suggesting that NOD1 and NOD2 induce ocular inflammation by distinct mechanisms involving IL-1beta. CONCLUSIONS These findings demonstrate that NOD1 is expressed within the eye and that its activation results in uveitis in an IL-1beta-dependent mechanism. Characterizing the differences between NOD1 and NOD2 responses may provide insight into the pathogenesis of uveitis.

Abstract
Background Costs and benefits of two Salmonella control policies for broiler production were described and compared. The control options were the Zoonosis Directive 92/117/EC and the more intense strategy, the Finnish Salmonella Control Programme (FSCP). Methods The comparison included the Salmonella control costs in primary and secondary production and the direct and indirect losses due to Salmonella infections in humans in 2000. Results The total annual costs of the FSCP were calculated to be 990 400 EUR (0.02 €/kg broiler meat). The average control costs in the broiler production chain were seven times higher with the FSCP than with the Zoonosis Directive alone. However, the public health costs were 33 times higher with the Zoonosis Directive alone. The value of one prevented loss of life per year exceeded the annual control costs of the FSCP. Conclusion Due to significant savings in public health costs compared to costs of FSCP, the FSCP was found to be economically feasible.

Abstract
Acute anterior uveitis (AAU) is the most common form of intraocular inflammation, but its aetiology is still unclear. Fifty percent of AAU patients are HLA-B27-positive, and half of these also have spondyloarthropathies (SpA). Numerous serological studies have shown elevated levels of serum antibodies to various Gram-negative bacteria in HLA-B27-positive AAU and SpA patients. Antigenic similarities between these bacteria and host components (HLA-B27) have already been shown. Still, the mechanism underlying these diseases has not been clarified. Among the Gram-negative bacteria, Helicobacter pylori has not been screened in AAU patients. The purpose of our study was to see if this common human pathogen somehow interferes with AAU. In addition Chlamydia trachomatis, Yersinia enterocolitica 03 and 09, Salmonella sp. and Proteus OX19 were also examined. A total of 60 patients consisting of 4 groups (15 patients with AAU, 15 with SpA, 15 with AAU+SpA and 15 healthy control persons) were examined. A high percentage of the serological results of all investigated bacteria was positive: 80% in the AAU, 93.3% in the SpA and 100% in the AAU+SpA group, while it amounted to 66.7% in the control group (p < 0.05). H. pylori showed the highest percentage of positivity in all 3 patient groups (66.7% in the AAU, 73.3% in the SpA and 80% in the AAU+SpA group). In contrast, 26.7% of the controls were anti-H.-pylori-positive, thus showing a statistically significant difference between the patients and the control group (p < 0.05). HLA-B27/B7-CREG positivity was detected in 53.3% of the AAU, 66.7% of the SpA and 93.3% of the AAU+SpA patients and in none of the controls. Our results suggest that H. pylori might be a candidate participating in the development of AAU and SpA. They also support the theory of genetic (HLA-B27) and exogenous factors (Gram-negative bacteria) as probable background of these diseases.

Abstract
Acute anterior uveitis is the most common form of uveitis. HLA-B27-associated acute anterior uveitis is a distinct clinical entity that has wide-ranging medical significance due to its ocular, systemic, immunologic, and genetic features. The association between HLA-B27 and the spectrum of HLA-B27-associated inflammatory diseases remains one of the strongest HLA-disease associations known to date. This review examines acute anterior uveitis with particular focus on HLA-B27-associated acute anterior uveitis, including the epidemiology, immunopathology, association with HLA-B27 and its subtypes, clinical features, complications, prognosis, and potential new therapies such as anti-TNFalpha therapy and oral HLA-B27-peptide tolerance. There have been substantial recent advances in both clinical and basic scientific research in this field, including studies of the various animal models of acute anterior uveitis and the HLA-B27 transgenic animals, and these are summarized in this review. To the ophthalmologist, HLA-B27-associated acute anterior uveitis is an important clinical entity that is common, afflicts relatively young patients in their most productive years, and is associated with significant ocular morbidity due to its typically recurrent attacks of inflammation and its potentially vision-threatening ocular complications. Furthermore, to the ophthalmologist and the internist, HLA-B27-associated acute anterior uveitis is also of systemic importance due to its significant association with extraocular inflammatory diseases.

Abstract
OBJECTIVE To study the infectious background of patients with a history of acute anterior uveitis (AAU) and healthy control subjects. METHODS Sixty four patients with previous AAU and 64 sex and age matched controls were studied. Serum antibodies to Salmonellae, Yersiniae, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Campylobacter jejuni, and Borrelia burgdorferi were measured using enzyme linked immunosorbent assay (ELISA), and antibodies to Chlamydia trachomatis and Chlamydia pneumoniae by microimmunofluorescence test. Peripheral blood mononuclear cells (PBMCs), separated by density gradient centrifugation, were studied for Salmonella and Yersinia antigens by means of an immunofluorescence test, and for C pneumoniae DNA with a polymerase chain reaction (PCR). RESULTS Neither prevalence nor levels of single microbial antibodies studied differed between the patients and control subjects, or between subgroups of patients created on the basis of clinical characteristics. In logistic regression analysis, the high number of recurrences (>10) of AAU was independently related to the presence of single or multiple bacterial antibodies (p=0.04). None of the PBMC samples of the patients were positive for Yersinia or Salmonella antigens. C pneumoniae PCR was positive in a patient who was negative for C pneumoniae antibodies. CONCLUSION Although neither the prevalence nor the levels of single microbial antibodies studied differed between the patients and the controls, current data suggest that the presence of single or multiple antibodies in patients with many recurrences of AAU compared with patients with none or few recurrences may be a sign of repeated infections, antigen persistence, or raised innate immune responsiveness.

Abstract
Eye inflammation, especially uveitis, is a prominent feature of spondyloarthropathies. Uveitis associated with ankylosing spondylitis and Reiter's syndrome usually is a unilateral acute anterior uveitis with a high tendency to recur sometimes in the contralateral eye. Uveitis associated with undifferentiated spondyloarthropathy, inflammatory bowel disease, and psoriasis may be less characteristic in its presentation, with a higher tendency to posterior pole involvement, bilaterality, and chronicity. Although acute anterior uveitis is grouped into the spectrum of human leukocyte antigen B27-related disease, other genetic and environmental factors including infections by gram-negative bacteria and gut inflammation can play a role in its pathogenesis. The prognosis of uveitis usually is excellent with topical treatment, and only those with posterior pole involvement or a high tendency to recur or to chronicity might benefit from immunosuppressive therapy.

Abstract
We studied the case records of 1122 patients with endogenous uveitis including 418 new cases treated at the University Eye Clinic in Turku during the years 1980-1982 and 1988. The mean annual incidence and prevalence rates (per 100,000 population) of idiopathic acute anterior uveitis were 17.1 and 48.5, respectively, sarcoid anterior uveitis 0.5 and 1.5, Posner-Schlossman syndrome 0.4 and 1.9, herpes zoster uveitis 0.4 and 0.7, idiopathic chronic anterior uveitis 0.3 and 7.3, herpes simplex keratouveitis 0.3 and 0.5, juvenile rheumatoid arthritis 0.2 and 2.4, Fuchs' heterochromic iridocyclitis 0.2 and 0.5, intermediate uveitis 0.3 and 1.4, and of toxoplasmic retinochoroiditis 0.3 and 2.4. The incidence and prevalence rates of acute anterior uveitis associated with ankylosing spondylitis were 2.0 and 10.3 per 100,000 population, respectively, and this disease association occurred more often in men than in women (p < 0.001). The mean annual incidence of idiopathic acute anterior uveitis was significantly lower in the age group 0-19 years than in the other age groups (p < 0.001).

Abstract
Acute anterior uveitis (AAU) or iritis is an inflammatory disorder of the anterior structures of the eye that may be associated with a number of disease entities. A significant proportion of patients will have no evidence of an underlying disorder and are labeled as idiopathic. Within this group approximately 50% will possess the human leukocyte antigen, HLA-B27, and some will have an associated spondyloarthropathy such as ankylosing spondylitis or Reiter's syndrome. Nevertheless, a number of HLA-B27-positive patients have no apparent underlying rheumatic disorder. The potential interplay of HLA-B27 and certain infective agents in the pathogenesis of AAU is discussed with particular reference to Yersinia species. Presentation of a uveitogenic peptide, similar to the arthritogenic peptide model in spondyloarthropathies, may be a mechanism involved in the development of AAU. Experimental models in animals have increased our understanding of the roles of retinal proteins and bacterial peptides, as well as T cells and cytokines, in the pathogenesis of uveitis. As in animal models of arthritis, certain retinal peptides (in conjunction with adjuvant therapy) can induce uveitis in animals. The treatment of isolated AAU usually involves topical medication and the prognosis is good. Occasional cases, especially those associated with systemic disorders, may require the addition of systemic corticosteroids or other immunosuppressive medications.

Abstract
PURPOSE To define the natural history of post-Salmonella-infection reactive arthritis (ReA) in a point source cohort concurrently exposed to the same microorganism, and to determine any relationship between anti-Salmonella humoral immune response to the organism and clinical outcome at 5 years. PATIENTS AND METHODS A cohort of 423 Ontario Provincial Police officers with a clinical diagnosis of Salmonella food poisoning were defined in 1984. Five years following the food poisoning, a mail and telephone survey was carried out to determine all those who developed ReA within 3 months of the onset of dysentery. Medical and physiotherapy charts from an earlier study on the same cohort were incorporated. All patients with a history compatible with reactive arthritis were interviewed and examined. Serum was taken to determine the presence of isotypic antibodies to the lipopolysaccharide of the causative Salmonella typhimurium. RESULTS Twenty-seven of the 423 individuals with dysentery were identified as developing acute ReA. In one third of them, the arthritis resolved within 4 months of onset. Two thirds continued to have subjective complaints, mostly of minor significance. However, symptoms were severe enough to force a change in work for 4 patients. Another 4 patients had objective damage to joints radiographically. Objective changes to joints were documented on physical examination in 37% of ReA patients 5 years following onset of disease. IgA antilipopolysaccharide antibodies correlated with the severity and duration of disease. Tests of cellular immune function did not correlate with clinical variables. CONCLUSIONS Chronic symptoms persist 5 years after the onset of ReA in the majority of patients. Joint damage by physical examination and radiographic assessment correlate with functional disability. Some early clinical features of disease, including prolonged diarrhea during the acute illness, may predict a worse outcome. IgA antilipopolysaccharides may serve as a disease marker for late post-Salmonella-infection ReA.

Abstract
One hundred and fourteen patients with acute anterior uveitis were studied for the presence of the HLA-B27 tissue type, the prevalence of spondylitis and arthritis and the occurrence of gastro-intestinal and urogenital infections or diarrhoeal illness in the history. Eighty-seven (76%) were B27+ and 27 (24%) B27-. Forty-two (48%) of the B27+ group had ankylosing spondylitis (AS); 13 (30%) of them were females. Sacroilitis (SI) with no spinal involvement was present in 21 patients (24%), 13 (61%) males and 8 (38%) females. Peripheral arthritis occurred in 6 patients. Thus, 68 (78%) of the HLA-B27+ positive patients had inflammatory spinal and/or joint disease, compared with 1 (4%) of the HLA-B27- group (p less than 0.001). The AS diagnosis was unknown previous to our examination in 31% of the males and 54% of the females, and SI was undiscovered in 61% of the males and 62% of the females. The occurrence of acute enteric infections was significantly increased in the B27+ AAU group, compared with the B27- patients and the patients reported exacerbation of AAU in connection with episodes of diarrhoea. An increased occurrence of urogenital infections was shown only in co-comparison with the males of the B-27+ AAU group. Thirty-three out of 47 AAU patients assayed by enzyme immuno-assay (EIA) for the quantification of IgM, IgA and IgG antibodies against Klebsiella pneumoniae, E coli, and Proteus mirabilis had significantly raised antibody titres against one or more of the antibodies studied, as compared to 62 healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Acute anterior uveitis is a common ocular disease characterized by inflammation of the iris and ciliary body. In the majority of patients presenting with an acute attack of anterior uveitis, the only clues to the pathogenesis of this disease are its close association with the genetic marker HLA-B27 and the likely triggering role of a variety of gram negative bacteria. HLA-B27 acute anterior uveitis appears to be a distinct clinical entity frequently associated with the seronegative arthropathies, such as ankylosing spondylitis and Reiter's syndrome. Recent advances in our understanding of the structure and function of class I HLA molecules have revealed their fundamental function in antigen presentation and this has led to a reevaluation of their role in disease predisposition.

Abstract
To test the pathogenetic role of the phenotype MZ of alpha 1-antitrypsin/alpha 1-protease inhibitor (PI) in acute anterior uveitis (AAU) and in different rheumatic diseases we examined 360 unrelated patients including 93 with AAU alone, 24 patients with AAU and ankylosing spondylitis (AS), 21 patients with AAU and Reiter's disease (RD), 26 patients with AAU, AS, and RD 54 patients with AS alone, 16 patients with RD alone, 115 patients with rheumatoid arthritis (RA) alone, and 11 patients with psoriatic arthritis (PA) alone. Of the 164 AAU patients, 80 had a single attack, and 84 had repeated episodes. There were neither significant differences between different groups of the patients and 120 healthy controls nor between patients with AAU alone and patients with AAU and AS or RD in the frequencies of the PI phenotypes tested. The results indicate that the PI MZ type is not closely associated with AAU, AS, RD, RA and PA and that it does not play any role in determining whether AAU shows a pattern of a single attack or repeated episodes, and whether AAU occurs alone or together with AS or RD.

Abstract
In 2 cases of ReA seen during the acute phase and shown serologically to be due to Y. enterocolitica 0:3, the LT test showed a marked response using as antigen a freeze dried preparation of the causative organism. The test result correlated with the activity of the disease when repeated during a flare in the 1st case, and during remission in both. Patients with ReA/RS in general showed a significantly higher response to the yersinia and klebsiella antigens tested when compared to AS, suggesting an overall difference in cell-mediated immunity to these enteric bacteria. AS cases reacted significantly less than controls to K. pneumoniae under suboptimal conditions. K. pneumoniae was shown to enhance the LT response to yersinia, possibly through an adjuvant effect. This was found with AS, ReA and in controls, though whether it is of relevance in the etiopathogenesis of AS or ReA/RS remains far from clear. Acute non-traumatic synovitis of the knee, occurring de novo, or in association with psoriasis, inflammatory bowel disease, or as part of RS, may be accompanied by evidence of heightened reactivity to streptococci both by blood and synovial fluid mononuclear cells. In 1 case with serological evidence of streptococcal infection and erythema nodosum, these changes were found to parallel disease activity. ReA can, it appears, follow recent streptococcal infection, and be associated with B27.

Abstract
One hundred and seventy-five consecutive patients with acute anterior uveitis (AAU) were examined over a 24-month period. There was a significantly increased incidence of AAU during the months August to December (p less than 0.05). This increase was confined predominantly to the HLA-B27 negative group of patients (p less than 0.01). There was no significant monthly difference in incidence between males and females, between patients with first or recurrent attacks, or between patients with and without arthritis. These results suggest that seasonal environmental factors may play a role in the production of HLA-B27 negative AAU.

Abstract
Faecal samples obtained from patients with acute anterior uveitis (AAU) and healthy controls unconnected with hospitals were examined for the presence of Gram-negative micro-organisms reported to be associated with AAU. There was an increased recovery of Klebsiella spp. from AAU patients seen in the first and in the second week after onset of symptoms when compared with patients presenting three to four weeks after onset of symptoms (p less than 0.025 and p less than 0.05 respectively) or with healthy control subjects (p less than 0.005 and p less than 0.05 respectively). By the third to fourth week there was no difference in klebsiella recovery between AAU patients and controls. The increased faecal recovery of klebsiella in the first two weeks was predominantly in HLA-B27 positive patients or patients possessing antigens which cross-react with B27, namely, HLA-B7 CREG. The patients with faecal cultures positive for klebsiella had a higher mean ESR than patients with negative faecal cultures (p less than 0.05). Although there was an increase in recovery of faecal klebsiella from AAU patients with spondylarthritis when compared with AAU patients without arthritis, the difference was not statistically significant. These results suggest that some klebsiella micro-organisms may play a role in the aetiopathogenesis of AAU associated with HLA-B27 or HLA-B7 CREG.

Abstract
Although sometimes used to refer to any sterile arthritis occurring in association with infection, the term 'reactive arthritis' is better reserved for arthritis following sexually acquired nonspecific urethritis or enteric infections with organisms such as Shigella, Salmonella, Yersinia and Campylobacter, because these arthropathies are unified by a number of shared clinical characteristics and an association with HLA B27. This review suggests that these arthropathies may also share a common pathogenic pathway, triggered by an ' arthritogenic factor' common to the diverse microbes which cause the disease and modified by genetic factors other than HLA B27. Although uncommon, reactive arthritis is important because it could provide the key to understanding the other seronegative arthropathies and mechanisms basic to chronic inflammatory synovitis.

Abstract
Uveitis comprises a complex group of diseases in which morbidity may depend on the nature of the initial inflammation as well as on the genetic, hormonal, and emotional background of the patient. Uveitis is initiated in every instance by some form of tissue injury. This may occur as an attack on individual cells by organisms such as Toxoplasma gondii or Herpesvirus hominis. Autoimmune disease may be produced as a late result of microbe-induced injury. The development of specific forms of autoimmunity seems to be dependent upon genetic as well as hormonal factors, particularly estrogens. Tissue injury of immunologic origin takes several forms, such as cytotoxic damage from sensitized lymphocytes, immune complex-mediated injury, and injury from the oxidative products of inflammatory cells. In some cases, permanent alteration of uveal vascular permeability results. Recurrent uveitis may be attributed in some instances to the reappearance of infectious organisms in the target tissue. In other cases, recurrence of inflammation may be attributed to the localization of immune complexes in the uveal tract. Changes in immunoregulation can be attributed to pregnancy, aging, and emotional factors. Neurohumoral pathways related to stress-mediated changes in immunoregulation have recently been described in laboratory animals. These pathways may be linked with stress-related recurrences of uveitis in humans.

Abstract
Chlamydial immunofluorescence (IF) serology was determined in 118 patients with acute anterior uveitis (AAU), half of whom had anti-chlamydia antibodies. Men and women were equally affected. The chlamydial IF antibody titre was generally 1/16-64, but a few higher values were also measured. The age distribution, ocular pathology, and duration of AAU were identical in the chlamydial seropositive and seronegative patient groups. In the seropositive group there were 3 men with Reiter's syndrome. The prevalence of anti-chlamydia antibodies (50%) was higher than in other patients studied in the same laboratory. Further population studies are in progress to see whether our AAU patients represent an accumulation of chlamydial-positive persons.

Abstract
Twenty-eight cases of acute anterior uveitis in which raised antibody titres indicated yersinia infection as a possible causative factor in the disease were studied retrospectively. In most cases the antibodies belonged to the IgA class; in only 6 patients did the presence of IgM class antibodies indicate recent infection. In half the cases also antibody titres against Chlamydia were raised. The clinical features and course of the disease did not differ from those of acute anterior uveitis due to other causes.

Abstract
To determine the hereditary pattern of acute anterior uveitis, we examined seven families-one family with four cases, one family with three cases, and four families with two cases of acute anterior uveitis. A total of 16 patients with uveitis and 28 relatives underwent ocular examinations and serologic determination of HLA antigens, protease inhibitor alpha 1-antitrypsin typing, and X-ray examination of sacroiliac joints. Sacroiliitis was found in 11 of 16 patients (68.8%) and incomplete Reiter's disease in seven of 16 (43.8%). HLA-B27 antigen was found in all patients with uveitis and in six of 21 (28.6%) relatives. HLA-Cw1 antigen was found in nine of 14 (64.3%) patients with uveitis, often in the same haplotype with HLA-B27 antigen. HLA-DR4 antigen was found in seven of 11 (63.6%) patients with uveitis. There was no significant association of the alpha 1-antitrypsin variant MZ with uveitis. We believe that a pleiotropic gene associated with HLA-B27 antigen with autosomal dominant inheritance, incomplete penetrance, and variable expressivity may determine susceptibility to acute anterior uveitis in linkage disequilibrium with HLA-Cwl antigen.

An 18-year-old woman developed acute polyarthritis one week and bilateral, acute, mucopurulent conjunctivitis and sterile pyuria two weeks after onset of Campylobacter jejuni enteritis. The conjunctivitis resolved spontaneously in one week and the arthritis in two months. The patient had HLA-B27 antigen. Campylobacter organisms may lead to Reiter's syndrome in a patient with HLA-B27 antigen.
