ABSTRACT

PURPOSE: To compare the postoperative risk of inflammatory relapse in two groups of uveitic patients who underwent cataract surgery: one group had perioperative topical steroids alone and the other used topical and oral steroids. METHODS: Prospective, randomized, unmasked, duocentric clinical trial conducted at the University of Parma (Italy), and the Jules Gonin Eye Hospital of Lausanne (Switzerland). Patients with a history of non-infectious uveitis requiring cataract surgery in 2009-2013 were assigned to two groups of perioperative prophylaxis: (A) intensive topical steroids alone; (B) the same topical regimen combined with oral steroids. Uveitis relapse over a period of 6 months was assessed. RESULTS: In total, 52 eyes in 50 patients were randomized: 28 eyes were assigned to group A (topical) and 24 eyes to group B (topical + oral). Mean relapse-free survival time was 131 ± 11 days in group A and 150 ± 13 days in group B. This difference was not statistically significant (p = 0.42). At the end of follow-up, the groups were also comparable in terms of significant improvement in visual acuity (p < 0.01), mean central macular thickness (CMT) and IOP variation. CONCLUSIONS: Absolute and long-lasting control of ocular, and possibly systemic, inflammation predisposes uveitis patients to satisfactory results after cataract extraction and intraocular lens implantation. Despite a lower rate of recurrences following oral steroid supplementation, the efficacy of an intensive perioperative topical steroid regimen alone in preventing postoperative uveitis relapse was statistically comparable. Secondary outcomes were also comparable between the two groups. Transient IOP elevation should be expected until treatment discontinuation.

ABSTRACT

Purpose. Prospective, controlled cohort study to investigate possible alterations in brain glucose metabolism (CMRglc) in patients with Cogan's syndrome (CS). Patients and Methods. Functional mapping of the CMRglc was obtained by quantitative molecular imaging positron emission tomography, combined with computed tomography (FDG-PET/CT). The patients were divided into three clinical groups: typical CS; atypical CS (ACS); autoimmune inner ear disease (AIED). The unmatched control group (CG) consisted of subjects requiring FDG-PET/CT for an extracranial pathology. Statistical mapping searched areas of significant glucose hypometabolism in all the affected patients (DG) and in each clinical subgroup. The results were compared with those of the CG. Results. 44 patients were enrolled (DG) and assigned to the three study groups: 8 patients to the CS group; 21 patients to the ACS group; and 15 to the AIED group. Sixteen subjects formed the CG group. Areas of significant brain glucose hypometabolism were identified in all the study groups, with the largest number and extension in the DG and CS. Conclusions. This study revealed areas of significantly altered CMRglc in patients with CS (any subform) without neurologic complains and normal conventional neuroimaging. Our results suggest that FDG-PET/CT may represent a very useful tool for the global assessment of patients with Cogan's syndrome.

ABSTRACT

Vitamin A deficiency is a rare but vision threatening disorder in the developed world, which can lead to blindness for severe keratomalacia with cornea scarring and perforation or night blindness due to impaired dark adaptation. Conversely, the disease is quite common in developing countries, as a consequence of chronic malnutrition. The correct diagnosis and therapy with prompt vitamin A supplementation avoid blindness. We report a series of 3 local cases with different age and causes for vitamin A deficiency. The diagnostic workup, therapy, and prognosis are discussed.

ABSTRACT

Neuro-Behçet's disease (NBD) involves the central nervous system; peripheral nervous system involvement is not often reported. NBD is quite common in adult patients and occurs rarely during childhood and adolescence. Young patients may share symptoms and signs of NBD with other neuro-ophthalmological disorders (e.g. idiopathic intracranial hypertension); thus, making the differential diagnosis difficult. Neuroimaging is mandatory and necessary for a correct NBD diagnosis but in children radiological examinations are often difficult to perform without sedation. From 1971 to 2011, 130 patients aged ≤16 years have been reported with NBD, according to retrospective surveys, case series, and case reports. The origin of the reported cases met the well-known geographical distribution of Behçet's disease (BD); the mean age at presentation of neurological findings was 11.8 years, with male gender prevalence (ratio, 2.9:1). We considered in detail the neuro-ophthalmological features of the 53 cases whose neuroimaging alterations were described with an assigned radiological pattern of the disease (parenchymal: 14 cases, non-parechymal: 35 cases, and mixed: 4 cases). In 19/53 patients (36%), neuro-ophthalmological symptoms anticipated any pathognomonic sign for a BD diagnosis, or only occasional aphtae were recalled by the patients. Family history was positive in 17% of subjects. Headache was reported in 75% of the patients; in those presenting with cerebral vascular involvement, headache was combined to other symptoms of intracranial hypertension. Papilledema was the most frequently reported ophthalmological finding, followed by posterior uveitis. Treatment consisted of systemic steroids in 93% of patients, often combined with other immunosuppressive drugs (especially colchicine and azathioprine). Clinical recovery or improvement was documented in the large majority of patients. Nine subjects had definitive alterations, and one died. Based on our review and personal experience, a delayed diagnosis, and the consequently delayed immunosuppressive treatment, may favour permanent sequelae, in particular, optic atrophy.

ABSTRACT

PURPOSE: To assess the parameters for postmortem retinal tissue recovery and processing that affect the quality of RNA extracted from the retina/retinal pigment epithelium (RPE) complex. METHODS: RNA was extracted from retina/RPE samples. The RNA quality was determined based on qualitative/quantitative measurements made with a Bioanalyzer (Agilent) and on the expression of a long retinal gene (RPE65). After a pilot analysis on rats, ocular RNA was extracted from human donor eyeballs (group A) explanted according to conventional procedures for cornea transplantation. In a second experiment, another group of human donor eyeballs (group B) were processed in a much shorter time. The postmortem interval (T) comprised two periods: T1, the time between a donor's death and enucleation, and T2, the time between eyeball explantation and immersion of the excised retina/RPE sample in preservative solution (T = T1 + T2). RESULTS: A short T2 was correlated with good quality of RNA extracted from the retina/RPE complex (p = 0.043) and successful expression of a tissue-specific gene (p = 0.007). No other parameter appeared to influence RNA quality. CONCLUSIONS: The time between eyeball explantation and immersion of the retina/RPE sample in preservative solution was the chief parameter affecting the quality of RNA extracted from the retina/RPE complex.

ABSTRACT

PURPOSE: Aim of the present study was to validate a statistical model to predict a severe course of anterior uveitis (AU) in patients with juvenile idiopathic arthritis (JIA). METHODS: Consecutive patients with newly diagnosed uveitis have been followed for at least 1 year with a standardized protocol. For each patient, demographic, clinical and laboratory characteristics, including time interval between arthritis and uveitis onset, α(2)-globulins level at arthritis onset, number of uveitis relapses/year, ocular complications and therapy and visual acuity, have reported. The validation procedure included the assessment of sensitivity, specificity and efficiency of previously published statistical model (Zulian et al. J Rheumatol 2002; 29: 2446-2453) in a new inception cohort of patients during a short length follow-up. RESULTS: Sixty patients with JIA, followed at 14 paediatric rheumatology-ophthalmology centres in Italy, entered the study. The mean age at arthritis onset was 4.4 years (range 1.2-15.8 years), and the mean interval time between arthritis and uveitis onset was 1.8 years (range: 0.0-14.2 years). After the first AU, patients, followed for a mean of 3.2 years, had a mean of 2.9 uveitis relapses. Twenty-two patients (36.7%) presented at least one complication. Using a probability cut-off value = 0.7, the statistical model revealed 80% sensitivity, 58% specificity and 65% efficiency. CONCLUSION: The time interval between arthritis and uveitis onset resulted as the main predictor of severe course uveitis in JIA. The statistical model was able to predict the development of a severe course in 8 of 10 patients.

ABSTRACT

BACKGROUND/AIMS: Ocular factitious lesions involving the conjunctiva alone represent a challenging diagnosis for the ophthalmologist; corneal integrity, in fact, allows maintenance of good visual acuity and precludes the pain subsequent to trigeminal stimulation. Conjunctival biopsy is crucial to make a diagnosis and to focus on possible peculiarities in the patient's behavior. A psychiatrist has to confirm the diagnosis. In this case report, images of a bilateral pseudo-membranous conjunctivitis sparing the cornea in an anorexic adolescent boy are shown. METHODS: Photographically documented case report. RESULTS: A fourteen-year-old Italian boy was referred with a diagnosis of bilateral chronic conjunctivitis unresponsive to systemic and topical antibiotic and steroidal treatment. It had lasted for 4 months and was concomitant with an 8-kg weight loss. Conjunctival biopsy revealed cotton wool fragments. The patient admitted an unsafe behaviour lasting for months. A diagnosis of factitious conjunctivitis was made, and confirmed by a psychiatric assessment. CONCLUSION: Factitious lesions of the eye involve not only anatomical structures situated on the visual axis causing a reduction of visual acuity, but may also involve the conjunctiva alone. A thorough clinical history should identify the source of the patient's anxiety. Moreover, close cooperation between ophthalmologists and a psychiatrist can further clarify the diagnosis.

ABSTRACT

BACKGROUND: Measles Mumps Rubella (MMR) vaccination is known to cause some serious adverse events, such as fever, rash, gland inflammation and neurologic disorders. These include third and sixth cranial nerve palsies. RESULTS: The case reported describes a partial recurrent oculomotor palsy associated with systemic symptoms following MMR vaccination in a healthy young child. The oculomotor palsy did not recover completely during the follow-up. CONCLUSIONS: Most of the times, measles, mumps and rubella cause mild illness and discomfort; but can also have serious or fatal sequelae. MMR vaccination has been proved to be safe and to reduce significantly the number of reported infections due to these viruses. However, significant adverse events can occur and paediatricians and public health operators should be aware of this aspect.

ABSTRACT

BACKGROUND: Rituximab is a monoclonal antibody inducing depletion of B lymphocytes and presently approved for the treatment of non-Hodgkin's lymphoma and rheumatoid arthritis. Here is the first report of the use of this drug in a case of Cogan's syndrome (CS). CASE PRESENTATION: a 25-year-old Italian woman was referred with conjunctival hyperaemia, interstitial keratitis, moderate bilateral sensorineural hearing loss accompanied by tinnitus, dizziness, nausea and vertigo, poorly responsive to oral and topical steroidal therapy. Diagnosis of typical CS was made. The administration of a combined immunosuppressive treatment resolved ocular inflammation, dizziness, nausea, and vertigo but gave little results in controlling progressive hearing loss. A noticeable improvement in hearing function was documented by pure tone audiometry after infusion of Rituximab. DISCUSSION: in CS, hearing function is often the most difficult parameter to control with therapy. A positive effect of Rituximab on was observed in our case. The drug also allowed to significantly reduce the number of adjuvant immunosuppressive medications.

ABSTRACT

PURPOSE: To perform in vivo assessment of corneal alterations in patients with Cogan syndrome (CS) and to correlate these findings with prior histopathologic descriptions. METHODS: Four consecutive patients (8 eyes) presenting with typical CS underwent confocal microscopy examination. At the moment of evaluation, ocular inflammation was quiescent in all the patients. The images were studied singularly, and then compared to those obtained from 5 healthy controls. Statistical analysis was performed with Student t test. RESULTS: All the cases showed multiple brightly reflective deposits in the stroma with moderate reflectivity of the surrounding stromal tissue. The outer corneal layers and the endothelium were spared. In 3/4 of the patients, the nerve fibers of the subepithelial plexus were thin and poorly reflective, with interruptions and lack of the typical branching pattern. No cells different from keratocytes could be detected in either case or control eyes. Corneal vascularization was present in one case. In CS-affected eyes, corneal thickness was 552+/-62 microm on average, and endothelial cell count was 2466+/-288 cells/mm(2). Statistical significance was not reached compared to the control group. CONCLUSIONS: Confocal microscopy was able to provide detailed images of corneal alterations in CS. This confirmed the interstitial nature of the keratitis and showed an excellent accordance with prior histopathologic findings. The absence of inflammatory cell infiltration may be explained by the prolonged control of ocular inflammation in our patients, which may also have limited stimuli for corneal neovascularization.

ABSTRACT

Here we report the case of an immunocompetent 8-year-old child who developed acute retinal necrosis concomitant with a primary herpes simplex virus type I infection. Ocular inflammation changed along with the development of a specific antibody titer in the serum. This evidence suggests that the immune response of the host can significantly modulate the clinical aspect of the ocular infection.

ABSTRACT

PURPOSE: This study aimed to assess the effectiveness of a steroid-sparing immunosuppressive treatment (IST) protocol in the control of severe or steroid-resistant autoimmune ocular inflammatory diseases. METHODS: We carried out a prospective, non-randomized clinical study. Patients presenting with ocular inflammations that failed to respond adequately to steroids alone after monotherapy for a mean period of 9 +/- 2 months (internal control) were offered the option to switch to a combined IST. The protocol consisted of different immunosuppressive drugs added in a stepladder sequence, where each drug (including the steroids) was administered discontinuously. Main outcome measures were control of inflammation, visual acuity and safety of treatment. RESULTS: A total of 76 subjects (121 affected eyes) enrolled in the IST protocol. Mean length of follow-up was 43 +/- 15 months. Complete control of inflammation was achieved in 86% of patients. During the first year of IST, the rate of inflammatory recurrences/patient was 0.78 +/- 1.13. This ratio diminished further during succeeding follow-up. Mean best corrected visual acuity improved from 0.31 logMAR to 0.24 logMAR (p < 0.001). Blood pressure and uric acid blood levels significantly altered for the worse in the study group. CONCLUSIONS: Immunosuppressive treatment was effective in achieving inflammatory quiescence in a large majority of patients. The study also demonstrated the longterm safety of the protocol and its steroid-sparing effect.

ABSTRACT

BACKGROUND/AIMS: To determine the levels of cyclosporin A (CsA) in tears and the anterior segment of the eye following long-term oral intake for autoimmune diseases. METHODS: Subjects taking oral CsA to treat relapsing autoimmune ocular inflammation were included in this study. All of the patients had been quiescent for at least 6 months. In patients scheduled for cataract extraction (group A), the CsA levels in the blood, aqueous humour and anterior capsule of the lens were determined. In subjects not requiring surgical intervention (group B), CsA was measured in tears and blood. The samples were analysed using turbulent flow chromatography coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: There were 19 subjects in group A and 43 subjects in group B. CsA was detectable in all of the tear samples with a mean value of 22.4 +/- 20.2 ng/ml and there was a significant positive correlation between the CsA levels in tears and blood (P = 0.012). CsA was not detected in any of the surgical samples. CONCLUSION: LC-MS/MS proved very sensitive for detecting CsA in low-volume biological samples. CsA was present in human tears in proportion to the blood level after an average of 12 hours from the last oral intake.

ABSTRACT

OBJECTIVES: Autoimmune sensorineural hearing loss (ASNHL) is a relatively rare disorder which can lead to total deafness. At present, no specific laboratory test with adequate sensitivity and specificity is available to confirm the clinical suspicion of ASNHL. The aim of this study was to identify if evaluation of anti-hsp70 antibodies is an accurate diagnostic tool in patients affected by ASNHL. STUDY DESIGN: Prospective study. METHODS: During 4-year (2001-2005), all patients with SNHL who were referred to the Eye, Ear, Nose and Throat Department of Parma University, Italy, underwent specific tests to determine the autoimmune origin of the disease. Patients with a consistent suspicion of ASNHL underwent the routine serologic tests and a test for determination of anti-hsp70 antibodies. The same patients were divided into three groups: (1) idiopathic ASNHL; (2) ASNHL associated with ocular inflammation, i.e. Cogan's Syndrome; (3) ASNHL associated with a systemic autoimmune disease (SAD). The control group included: (1) healthy subjects; and (2) patients affected by SAD, without any ocular or audiovestibular disease. RESULTS: 88 subjects (67 patients, defined as "study group", and 21 controls) were evaluated. Anti-hsp70 antibodies were isolated in 52% of the study group patients, and in 4% of the control group (chi2 = 13.009, p < 0.01). In the idiopathic ASNHL patients, 59.5% were found positive for anti-hsp70 antibodies. About 50% of patients affected by CS and 37.5% of patients affected by SAD with SNHL were found positive. In the control group, anti-hsp70 antibodies were found in 8.3% of healthy subjects and in none of the patients with SAD and no hearing loss. CONCLUSIONS: The present study confirms the value of the anti-hsp70 test in the serological diagnosis of autoimmune hearing loss. It is still the only available diagnostic marker that identifies an autoimmune origin of hearing loss.

ABSTRACT

The report describes the case of an adult patient presenting a severe, serologically proven, Toxocara endophthalmitis, unresponsive to the common surgical and medical approach (vitrectomy, anti-parasitic treatment followed by high-dose corticosteroids). The association of oral cyclosporin A to a lower dose of prednisone was successful in achieving a long-term control of the ocular inflammation without systemic side effects.

ABSTRACT

OBJECTIVE: The following is a case presentation of congenital syphilitic keratitis in a boy 6 years of age who was successfully treated with an immunosuppressive drug combination therapy. METHODS: Congenital syphilitic keratitis was diagnosed by clinical findings and laboratory tests. The child was unresponsive to traditional treatment; thus, systemic immunosuppressive therapy, which consisted of oral cyclosporine 4 mg/kg/d, 6 days per week, and oral low-dose steroids (fluocortolone 0.8 mg/kg a week, given every other day), was initiated. RESULTS: Corneal disease showed great improvement with this therapy, with progressive healing of lesions in the first month of treatment and no signs of toxic renal, hepatic, or growth abnormalities. Recurrences of uveitis have not occurred, and corneal interstitial keratitis episodes have been limited to 3 in an 8-year period. After 6 months with no recurrences, a tapering off of the systemic therapy was initiated, and the child is still asymptomatic and without flare-ups. CONCLUSIONS: Congenital syphilitic keratitis is usually treated with topical steroids and cycloplegic drugs, which not only can be ineffective but can also lead to complications such as cataract and glaucoma. In the present case report, a pediatric patient affected by syphilitic interstitial keratitis was treated successfully with an immunosuppressive drug combination therapy.

ABSTRACT

PURPOSE: To present two cases of pediatric Cogan Syndrome and to highlight the differences between the adult and pediatric forms of the disease, as well as the importance of early diagnosis and treatment. DESIGN: Interventional case report. METHODS: Institutional setting. RESULTS: Corneal lesions were much more diffuse than those observed in adult Cogan syndrome. Immunosuppressive drug combination therapy successfully resolved systemic and ocular inflammation, but the involvement of the pupillary area caused permanent low vision in one case and amblyopia in the other. CONCLUSION: When chronic ocular inflammation is observed in association with sensory neural hearing loss and any systemic signs of autoimmune inflammation, a diagnosis of Cogan syndrome should be suspected. If immunosuppressive treatment is not initiated as soon as possible, permanent low vision and deafness can result.

ABSTRACT

OBJECTIVE: To evaluate outcomes and issues pertaining to cochlear implantation in a group of subjects affected by Cogan syndrome. STUDY DESIGN: Prospective cohort. SETTING: Department of Ophthalmology and Otorhinolaryngology, University of Parma. PATIENTS: Five postlingually deafened adults suffering from a typical form of Cogan syndrome who underwent cochlear implantation. MAIN OUTCOME MEASURES: Benefit from cochlear implantation as measured by word and everyday sentence recognition tests. Surgical issues and postoperative complications were also evaluated. RESULTS: In two cases, intracochlear electrodes were inserted into the scala vestibuli because of the ossification of the scala tympani. Two patients experienced a recurrence of keratitis the day after surgery. To date, with a follow-up of 1 to 4 years, no patient has experienced flap complications or other local or systemic complications. At the 12-month postoperative evaluation, all patients had gained useful open-set speech perception, achieving a mean score of 91% and 95% on word and everyday sentence recognition tests, respectively. CONCLUSIONS: Patients deafened by Cogan syndrome demonstrated high levels of speech understanding after undergoing cochlear implantation. Obliteration of the cochlea may complicate electrode implantation, requiring modifications of the surgical technique. Stress consequent to the surgical procedure may instigate an acute phase of the basic illness.
