In a placebo-controlled, double-masked clinical trial, the authors evaluated the effects of topical 2% cyclosporine on 20 patients with vernal keratoconjunctivitis (VKC). Nineteen patients were male and one was female. Patients ranged in age from 5 to 19 years (mean, 9.7 years). Symptoms of itching, tearing, photophobia, discharge, and foreign body sensation were evaluated and recorded at weekly intervals for a period of 6 weeks. There was a statistically significant decrease in the conjunctival hyperemia, papillary hypertrophy, punctate keratitis, and Trantas' dots in the group of patients treated with cyclosporine but not in the group treated with placebo. No adverse effects and no detectable levels of cyclosporine were noted in the blood in the cyclosporine-treated group. Cyclosporine appears to be safe and effective for the short-term treatment of VKC.

Thirty-six healthy male volunteers were enrolled in two sequential double-masked, placebo-controlled trials with the objective of assessing the safety and local tolerability of 2% cyclosporine ophthalmic ointment. Subjects were randomly assigned to active or placebo groups and dosed once, twice, or thrice daily for 14 days. Safety and tolerability were assessed through patient interviews, ophthalmologic examinations, routine laboratory testing, and blood cyclosporine assays. Relative to placebo, cyclosporine ointment was associated with higher frequencies of ocular burning, tearing, redness, itching, and headache. These intolerances were dose-related and reported predominantly in the TID group; QD and BID cyclosporine ophthalmic ointment were better tolerated than the placebo control. Symptoms were usually mild, were reported only once beyond Day 2 in the QD-BID groups, and never required interruption of the study. Transitory, asymptomatic, and unexplained elevations of serum transaminases were seen in five subjects in the first study, but were not confirmed in the second and are not felt to be drug-related. Cyclosporine blood levels were uniformly below the limits of detection. We conclude that the tolerability profile of 2% cyclosporine ointment, dosed once or twice daily in normal volunteers, is acceptable and supportive of trials in patient populations.

The effect of ten days' treatment with cyclosporin A, 5 mg/kg/day, in 10 adults with atopic dermatitis was investigated using a double-blind, randomized, placebo-controlled, cross-over design. Evaluation was based on itch recording, clinical scoring and immunohistochemical examination of skin biopsy specimens. Cyclosporin A significantly reduced the itch intensity, the eczema score and the consumption of topical hydrocortisone. A significant decrease in serum magnesium and in the total number of blood eosinophils was seen. No other laboratory abnormalities were observed. In lesional skin, Cyclosporin A induced a relative decrease of CD3+ T cells in 5/10 patients, of HLA-DR+ cells in 6/10, and of interleukin-2-receptor positive (CD25+) cells in 4/10. However, these changes in phenotype expression did not seem necessary for itch relief. Relapse of clinical symptoms was seen within 2-30 days of completion of the Cyclosporin A course. The mechanism of the antipruritic effect remains unclear, but the present findings may support the hypothesis that 'pruritogenic cytokines', whose production is inhibited by Cyclosporin A, may be important in the pathogenesis of itch in atopic dermatitis.

Twenty three patients with primary biliary cirrhosis surviving for greater than 1 yr after liver transplantation were studied. All reported marked symptomatic improvement, and had significant falls in serum bilirubin, alkaline phosphatase (p less than 0.0001), immunoglobulin M, and antimitochondrial antibody levels (p less than 0.005). Beyond 1 yr, liver biopsies showed features compatible with disease recurrence in 9 of 10 patients, and a further 4 patients developed pruritus or associated abnormalities. Immunoglobulin M levels were raised in 80%, with elevated antimitochondrial antibody titers in all those tested. Cyclosporine treatment in some patients initially given prednisone and azathioprine was followed by regression of histologic abnormalities. Of 102 patients with nonprimary biliary cirrhosis followed similarly, 50 underwent biopsy, and although 12 showed features of bile duct damage, all had additional histologic and clinical changes supporting an alternative diagnosis. These findings are consistent with previous reports that primary biliary cirrhosis can recur after transplantation, possibly modified by the use of cyclosporine.

We report a case of primary biliary cirrhosis-autoimmune hepatitis overlap syndrome treated with cyclosporine A. Features of primary biliary cirrhosis were pruritus, high titer of antimitochondrial antibodies, inflammatory infiltrates surrounding interlobular bile ducts, and periportal granuloma. Features suggestive of autoimmune hepatitis were high titer of antinuclear antibodies, very high total immunoglobulins, and piecemeal necrosis. Because corticosteroids and ursodeoxycholic acid were inefficient, cyclosporine A was started at a dose of 3 mg/kg/day. A dramatic improvement in clinical condition, liver tests, and histology was noted. Discontinuation of cyclosporine A was followed by a clinical and histological relapse. Cyclosporine A reintroduction was again associated with a significant improvement. This case report suggests that in corticoresistant cases cyclosporine A could be an effective therapy for primary biliary cirrhosis-autoimmune hepatitis overlap syndrome.

This trial was a randomized, double-masked, crossover study during which patients with keratoconjunctivitis sicca underwent 6 weeks of treatment with either cyclosporine 1% ophthalmic ointment or placebo followed by 6 weeks of the alternative treatment. Washout periods using only unpreserved artificial tears preceded both treatment cycles. Twenty-five patients completed the first treatment period, but only eight met entry criteria for period II. Cyclosporine ointment was associated with initial mild to moderate redness, itching, and burning that returned to baseline levels within 1-2 weeks. Rose Bengal results and results of four subjective (patient diary) efficacy parameters favored cyclosporine: foreign body sensation, overall symptoms, hours of symptom control per day, and overall effectiveness. No systemic adverse events or laboratory abnormalities occurred. We conclude that (a) the crossover design is inappropriate for studying this disease; (b) mild to moderate itching, redness, and burning occur initially with cyclosporine administration, although tolerance quickly develops; (c) cyclosporine appears to benefit the ocular surface in keratoconjunctivitis sicca; and (d) further trials in this syndrome are warranted.

Cyclosporin A seems to became more and more important in the treatment of atopic dermatitis. Open, prospective study: 8 weeks of treatment and 6 months of follow-up in wash-out. 15 patients were selected (10 males and 5 females) with mean age of 35.5. The patients were suffering of atopic dermatitis non responder to preceding treatments, and free from any pathological conditions contra-indicating the use of cyclosporin A. Cyclosporin A was orally administered at the dosage of 5 mg/kg/day for 8 weeks. The patients used a diary with a score from 0 to 3 for the following symptoms: extensions of skin lesions, itch and sleeping sickness. Treatment with cyclosporin A induced a significant improvement of the parameters evaluated. No significant side effects were observed. No relapses were recorded during the six months of follow-up.

One hundred percent of adult patients with chronic renal failure (CRF) develop cutaneous findings as a result of uremia or due to therapeutic interventions. To date, pediatric incidence studies have been limited to Caucasian children. However, recent reports have indicated that more African American patients progress to end-stage renal disease (ESRD). This is the first study to assess the prevalence of renal failure-related skin disease in children of color, including African American and Hispanic patients. Thirty children were evaluated by history and physical examination, with assignment to one of three treatment categories: transplanted (n = 10), dialyzed (n = 16), or medically managed (n = 4). Skin findings were divided into uremic, drug-related, or infectious disease types. The incidence of skin disease was 100%. Xerosis was the single most common finding, often accompanied by pruritus. Cushinoid features were common despite the addition of steroid-sparing agents. Cyclosporin A-treated African American children had a high incidence of gingival hypertrophy (72%) and an even higher incidence of hypertrichosis (100%). Acral warts and nevi were common findings, the latter correlating with the length of immunosuppression. There is a high incidence of cosmetically disfiguring side effects (Cushinoid facies, hypertrichosis, and gingival hypertrophy) in children within all treatment categories, primarily related to drug treatment. Further study is required to determine the long-term sequelae, including psychological disturbances, of cutaneous disease in children of color with CRF.

Ocular allergy is a common condition that usually affects the conjunctiva of the eye and is therefore often referred to as allergic conjunctivitis. The severity of the disease can range from mild itching and redness, as seen in seasonal allergic conjunctivitis, to the more serious vision threatening forms of ocular allergy which affect the cornea, such as atopic keratoconjunctivitis. The pathogenesis of allergic conjunctivitis involves a complex mechanism which centers around IgE-mediated mast cell degranulation and release of multiple preformed and newly formed inflammatory mediators. The diagnosis of allergic conjunctivitis is usually a clinical one which can be made based on a thorough history and careful examination. Treatment of ocular allergy should begin with conservative measures including allergen avoidance, environmental control, ocular irrigation and cold compresses. Pharmacotherapy of allergic conjunctivitis consists of several classes of drugs. Antihistamines are widely used to treat mild conditions such as seasonal and perennial conjunctivitis and potent new agents such as levocabastine and emedastine are now available. Mast cell stabilizers such as sodium cromoglycate are both safe and effective and are commonly used in ocular allergy. More effective mast cell stabilizers such as nedocromil, lodoxamide and olopatadine are now being used. Nonsteroidal antiinflammatory drugs have demonstrated only limited efficacy and, as such, are not widely used. Topical steroids are very effective in treating signs and symptoms but are reserved for only refractory cases due to their serious side effects. Loteprednol and rimexelone are newer corticosteroids which reportedly have less of an effect on intraocular pressure. Cyclosporine has recently been shown to be highly effective in cases of vernal keratoconjunctivitis and atopic keratoconjunctivitis while producing no adverse effects.

Acute systemic toxoplasmosis was diagnosed in a 4-5-year-old, male, Domestic Short Hair cat, which had been on cyclosporine A immunomodulatory therapy for feline atopy, over an 8-month period. Cyclosporin A (CsA) has shown promising results as a immunosuppressive agent in the cat for the treatment of eosinophilic plaque and granulomas, allergic cervico-facial pruritus, feline atopy and other immune-mediated dermatoses. However, inhibition of T-lymphocyte function by CsA is believed to have predisposed this cat to the development of a newly acquired, acute Toxoplasma gondii infection, as characterized by severe hepatic and pancreatic pathology in conjunction with the heavy parasite load demonstrated on immunohistochemical (IHC) stains for T. gondii. Cats on CsA therapy appear to be at risk of developing fatal systemic toxoplasmosis.
