Abstract
INTRODUCTION Ocular inflammatory diseases comprise uveitis, scleritis, and inflammation of adjacent structures of the eye. Therapy may be challenging and often involves corticosteroids and immunomodulatory agents. AREAS COVERED This review describes the genes involved in noninfectious ocular inflammatory diseases and focuses on pharmacogenetic studies regarding different classes of anti-inflammatory drugs used in the management of uveitis, including corticosteroids, antimetabolites, calcineurin inhibitors, alkylating agents, and biological agents. EXPERT OPINION Pharmacogenetics holds the promise of a personalized medicine with potential to customize treatment that can achieve the best clinical response and avoid toxicity. Several polymorphisms in various genes involved in the metabolism of drugs commonly utilized in the treatment of ocular inflammatory diseases have been described. Most promising is the polymorphism in thiopurinemethyltransferase gene for which a genotype analysis can reveal slow metabolizers of azathioprine and help avoid serious drug toxicity. Although pharmacogenetic studies with specific focus on ocular inflammatory diseases are lacking, knowledge from studies in rheumatologic diseases and transplant medicine can provide a platform for future research. Prospective clinical studies are needed to determine the clinical significance of such polymorphisms and their true effect on drug metabolism and side effects.

Abstract
INTRODUCTION Uveitis is an intriguing group of disorders characterized by inflammation of the uveal tract. Due to the potential grave consequences of the disease process, it is important to assess the various therapeutic options available for treating uveitis, and their outcomes. AREAS COVERED This review discusses the use of conventional agents in the management of uveitis, including discussion of the molecular and clinical properties of corticosteroids, antimetabolites, calcineurin inhibitors and alkylating agents and their side effects. In addition, it also discusses the molecular and clinical properties of novel biologic agents and their side effects. Moreover, recommendations as to when biologic agents should be employed are also discussed. EXPERT OPINION We recommend that in general (except in selected cases of Adamantiades-Behçet's disease) biologics should not be used as a first-line therapy for uveitis due to inconvenience, high cost, and potential immunosuppressive effects. However, many biologics are potent in inducing drug-free remission of uveitis and may be employed to manage recurrent diseases or diseases not responsive to conventional agents.

Abstract
OBJECTIVES To conduct an evidence-based review of the common medication toxicities and strategies and utility of drug toxicity monitoring among patients with systemic lupus erythematosus (SLE). METHODS PubMed and other databases were searched for articles published between the years 1960 and 2010 for keywords referring to medication toxicity or monitoring strategies for 7 drugs commonly used in SLE. All relevant English-language articles were reviewed. Most of the evidence we reviewed comprised studies that addressed the incidence of toxicity-randomized trials that compare different monitoring strategies for these drugs do not exist. RESULTS Data to describe the frequency of adverse events and appropriate strategies for screening for these events are scarce. Toxicities do not appear to be substantially more common among patients with SLE compared to other conditions for which these drugs are used. CONCLUSIONS Our review demonstrates that the scientific basis for many aspects of drug toxicity monitoring is weak and that most current recommendations are based largely on expert consensus. We present a future research agenda to address these gaps.

Am J Ophthalmol 2010; 149:423-32.e1-2.

Abstract
PURPOSE To evaluate mycophenolate mofetil as a single noncorticosteroid immunosuppressive treatment for noninfectious ocular inflammatory diseases. DESIGN Retrospective cohort study. METHODS Characteristics of patients with noninfectious ocular inflammation treated with mycophenolate mofetil at 4 subspecialty clinics from 1995 to 2007 were abstracted by expert reviewers in a standardized chart review of every eye at every visit. Main outcomes measured were control of inflammation, corticosteroid-sparing effects, and discontinuation of mycophenolate mofetil (including the reasons for discontinuation). Survival analysis was used to estimate the incidence of outcomes, and to identify risk factors for each. RESULTS Among 236 patients (397 eyes) treated with mycophenolate mofetil monotherapy, 20.3%, 11.9%, and 39.8% had anterior uveitis, intermediate uveitis, and posterior uveitis or panuveitis respectively; 14% had scleritis; 7.6% had mucous membrane pemphigoid; and 6.4% had other ocular inflammatory diseases. By Kaplan-Meier estimation, complete control of inflammation--sustained over consecutive visits spanning at least 28 days--was achieved in 53% and 73% of patients within 6 months and 1 year respectively. Systemic corticosteroid dosage was reduced to 10 mg of prednisone or less, while maintaining sustained control of inflammation, in 41% and 55% of patients in 6 months and 1 year respectively. Twelve percent of patients discontinued mycophenolate mofetil within the first year because of side effects of therapy. CONCLUSIONS Given sufficient time, mycophenolate mofetil was effective in managing ocular inflammation in approximately half of the treated patients. Treatment-limiting side effects were observed in 12% of patients and typically were reversible.

Abstract
Mycophenolate mofetil (MMF) is an immunosuppressive agent used in transplantation. Over the last decade, MMF has also emerged as an alternative therapeutic regimen for autoimmune diseases, mainly for patients refractory to other therapies. The active compound of MMF, mycophenolic acid (MPA), depletes the intracellular pool of guanosine tri-phosphate through inosine monophosphate dehydrogenase blockade. The molecular mechanism involved in the elimination of T and B lymphocytes upon inhibition of inosine monophosphate dehydrogenase remains elusive. In this study, we showed that in contrast to the immunosuppressors azathioprine, cyclosporin A, and tacrolimus, MPA killed lymphocytes through the activation of a caspase-independent necrotic signal. Furthermore, the MPA-mediated necrotic signal relied on the transmission of a novel intracellular signal involving Rho-GTPase Cdc42 activity and actin polymerization. In addition to its medical interest, this study sheds light on a novel and atypical molecular mechanism leading to necrotic cell death.

Abstract
Over recent decades short- and medium-term survival has greatly improved in patients affected with systemic lupus erythematosus, but long-term prognosis still remains poor mainly due to complications of the disease and/or its treatment. To improve long-term prognosis in systemic lupus erythematosus, we should try to adopt, early in the disease course, strategies that can contribute to reducing long-term complications, including screening for and prophylaxis against infections, control of risk factors for atherosclerosis, and cancer surveillance. However, in patients with systemic lupus erythematosus all these preventive strategies are often not sufficient. Indeed, two important systemic lupus erythematosus-related factors play a relevant role in all these complications: severe disease manifestations, such as glomerulonephritis and central nervous system involvement, and corticosteroid and cyclophosphamide use. Therefore, to prevent long-term complications, we should try to control disease activity and severity using the lowest effective dosage of these drugs. Moreover, strategies directed at preventing clinical manifestations in asymptomatic antinuclear antibody-positive individuals or in antiphospholipid antibody-positive systemic lupus erythematosus patients, as well as at preventing severe manifestations in patients with mild systemic lupus erythematosus at the time of the diagnosis should be considered.
