Association between anxiety and depression in patients with acute coronary syndromes due to financial crisis.

BACKGROUND: The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. AIM: To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. METHODS AND RESULTS: Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. CONCLUSIONS: Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

Pars plana vitrectomy versus immunomodulatory therapy for intermediate uveitis: a prospective, randomized pilot study.

PURPOSE: Comparison of pars plana vitrectomy (PPV) with immunomodulatory therapy (IMT) for patients with intermediate uveitis (IU). METHODS: A prospective, randomized pilot study was performed on patients with recalcitrant IU associated with degradation of visual acuity (VA) despite standard treatment. Outcome measures (VA, intraocular pressure, anterior chamber and vitreous cellular infiltrate) were collected. RESULTS: Sixteen patients (18 eyes) were randomized to the PPV IMT group. Nine of 11 eyes (82%) treated with PPV showed resolution of inflammation at follow-up, at 5.93 years. Four of 7 eyes (57%) given IMT had persistent inflammation requiring subsequent PPV. PPV patients showed greater improvement in Snellen line, IOP, and vitreous cell reduction. Three PPV patients had cystoid macular edema (CME) initially; all resolved postoperatively. CME improved in 2 of 3 eyes using IMT. CONCLUSIONS: A higher percentage of patients treated with PPV had improvement of uveitis compared to those given IMT. A multicentered clinical trial is needed to confirm and statistically validate these conclusions.

Daclizumab for treatment of birdshot chorioretinopathy.

OBJECTIVE: To report the outcomes for daclizumab in the treatment of birdshot chorioretinopathy (BSCR) refractory to traditional immunomodulatory therapy (IMT). METHODS: We retrospectively reviewed medical records of 8 patients with BSCR whose disease was refractory to or who were intolerant of traditional IMT. All patients received 1 mg/kg of daclizumab intravenously at 2-week intervals initially at 1 referral uveitis practice. Main outcome measures were changes in visual acuity, vitreous inflammation, fluorescein angiographic pathologic features, electroretinography (ERG) parameters, concomitant IMT requirements, and adverse events. RESULTS: Over a mean follow-up of 25.6 months, 7 patients had either stabilization or improvement in visual acuity of both eyes and complete resolution of vitreous inflammation. Six patients had resolution of vasculitis on fluorescein angiography. The ERG 30-Hz implicit times and the bright scotopic amplitudes worsened in some patients despite abolition of clinically evident inflammation. Four patients were able to discontinue all other IMT and remain inflammation free while receiving only daclizumab treatment. Two patients developed adverse effects that led to daclizumab treatment discontinuation. CONCLUSIONS: Daclizumab therapy was effective in stabilizing vision and decreasing inflammation in most patients with BSCR. The ERG parameters continued to decline in some patients despite adequate inflammatory control. Regular serologic monitoring is critical to detect adverse events.

Mooren ulcer: an immunopathologic study.

PURPOSE: To determine the pattern and distribution of mononuclear cells, adhesion, and co-stimulatory molecules in the conjunctiva of patients with Mooren ulcer. METHODS: Conjunctival biopsy specimens were obtained from 6 patients with Mooren ulcer and 6 healthy individuals. Immunohistochemistry was performed on frozen sections of the cryopreserved human conjunctivas using monoclonal antibodies directed against CD1alpha, CD3, CD4, CD8, CD20, CD25, CD57, and CD68 cells; the adhesion molecules E-selectin, vascular cell adhesion molecule-1 (VCAM-1), very late activation-4 (VLA-4), ICAM-1, and LFA-1; and the co-stimulatory molecules CD28, B7-1, B7-2, and CTLA-4. RESULTS: Differences in expression on the conjunctival epithelium from patients with Mooren ulcer and normal subjects were noted only for VCAM-1, VLA-4, ICAM-1, and LFA-1. The ratio of CD4+/CD8+ cells in Mooren ulcer specimens was significantly higher (3.5-fold). However, in the substantia propria, Mooren ulcer specimens revealed significantly increased numbers of CD1alpha+, CD3+, CD4+, CD20+, CD28+, B7-1+, B7-2+, and CD68+ cells. The ratios of CD4+/CD8+ cells and B7-2+/antigen-presenting cells in Mooren ulcer specimens were significantly higher (5-fold). All tested adhesion molecules showed significant up-regulation in the patients' conjunctivas. Mooren ulcer vascular endothelial cells prominently expressed E-selectin, VCAM-1, VLA-4, and ICAM-1 compared with normal conjunctiva. CONCLUSION: The simultaneous presence of multiple types of inflammatory cells, adhesion, and co-stimulatory molecules in Mooren ulcer conjunctiva suggests that their interaction may contribute to a sustained immune activation as at least part of the pathogenic mechanism of this disorder.

Conjunctival non-caseating granulomas in a human immunodeficiency virus (HIV) positive patient attributed to sarcoidosis.

PURPOSE: To report a rare case of isolated ocular sarcoidosis in an HIV positive patient. DESIGN: Case report. METHODS: A 47-year-old HIV+ Caucasian male was referred for chronic bilateral follicular conjunctivitis. RESULTS: A conjunctival biopsy that was performed on the right eye showed sarcoidosis. General medical evaluation including a spiral thin cut chest CT scan revealed no systemic involvement. The ocular signs and symptoms resolved completely with topical corticosteroid treatment. CONCLUSIONS: HIV infection and sarcoidosis rarely coexist, presumably because their immunopathogenesis mechanisms diverge. In the absence of systemic involvement, a definite diagnosis can only be made by biopsy of the ocular tissues.

Primary intraocular lymphoma: A review.

Primary intraocular lymphoma (PIOL) is a type of primary central nervous system lymphoma (PCNSL). It is the most common neoplastic masquerade syndrome involving the eye. Its protean ocular manifestations, plus in many cases the initial positive response to corticosteroid therapy for presumed uveitis, delay accurate diagnosis. A high index of suspicion is essential, followed by tissue biopsy with cytology and ancillary studies. Current treatment is based on chemotherapy featuring high-dose methotrexate and radiation therapy. Prognosis is poor due to CNS involvement, but newer therapies have had some success in prolonging survival.

Masquerade scleritis.

PURPOSE: To report two cases in which malignancy masqueraded as scleritis, delaying the diagnosis. METHODS: Two patients initially diagnosed and treated for unilateral scleritis were referred for management of persistent inflammation. Additional evaluation uncovered underlying malignant processes. RESULTS: The first patient presented with scleritis initially responsive to systemic corticosteroids, with relapse one month later. Upon referral, peripheral fundus examination revealed elevated lesions. Additional studies confirmed the diagnosis of choroidal melanoma. The patient was treated with proton-beam irradiation. The second patient developed necrotizing scleritis unresponsive to systemic steroids, methotrexate, and cyclophosphamide. A scleral biopsy disclosed an undifferentiated high-grade carcinoma, likely metastatic. Exenteration was performed. CONCLUSIONS: Scleritis can present a diagnostic challenge. It is often the sole initial manifestation of an occult systemic problem. Treatment-resistant scleritis should raise the suspicion of an infectious or malignant masquerade.

Ahmed valve implantation for uncontrolled pediatric uveitic glaucoma.

PURPOSE: We sought to evaluate the safety and efficacy of Ahmed valve implantation for the management of glaucoma associated with chronic uveitis in pediatric patients. METHODS: A retrospective chart review was conducted of 6 pediatric patients (7 eyes) who underwent Ahmed valve implantation because of refractory uveitic glaucoma. Intraocular pressure (IOP) reduction, preoperative and postoperative visual acuities, the number of hypotensive medications required, and complications associated with the operation were evaluated. RESULTS: Mean follow-up was 36.8 months (range, 6-60). At the last visit, all 7 eyes had IOPs between 9 and 18 mm Hg (average, 12.1). IOP reduction averaged 69.6% (P = 0.0005, paired t-test). The number of hypotensive agents was reduced from an average of 3 to an average of 0.71 medicines per eye (P = 0.001). The only complication was hemorrhagic choroidal detachment postoperatively in two eyes; both resolved within one month. CONCLUSIONS: For children with good immunomodulatory control of their inflammation and appropriate follow-up, Ahmed valve implantation can be an effective and safe procedure for treating pediatric uveitic glaucoma.
