Comparison of mizolastine with loratadine in the treatment of perennial allergic rhinitis.

Mizolastine is a new, non-sedating antihistamine providing satisfactory symptomatic relief in seasonal allergic rhinitis. The purpose of this study has been to compare mizolastine to loratadine in perennial allergic rhinitis. This multicentre, double-blind study has involved 68 patients, randomly allocated, after a one-week placebo run-in, to 10 mg mizolastine or 10 mg loratadine, both given on a once-daily basis, for four weeks. Comparable symptom relief occurs in both groups resulting, respectively for mizolastine and loratadine, in a 66.6% and a 61.3% decrease in total nasal score, to a 74.8% and a 76.4% decrease in total ocular score, and to a 69.0% and a 64.8% decrease in global total score. Safety is satisfactory in both groups. Mizolastine is at least as effective as loratadine in relieving perennial allergic rhinitis symptoms and its safety profile allows its use in the treatment of this disease.

Intranasal treatment with lysine acetylsalicylate in patients with nasal polyposis.

Forty-three patients suffering from nasal polyposis underwent intranasal treatment with increasing doses of lysine acetylsalicylate (LAS) corresponding to 20, 200, and 2000 micrograms of aspirin (ASA), until a maximal dose of 2000 micrograms weekly was reached. The patients were divided in two groups: a group of 28 patients with ASA intolerance, including 20 with ASA triad, and a group of 15 patients without ASA intolerance. The local treatment was usually started 1 month after polypectomy and was well tolerated without side effects. A control group included 191 subjects with nasal polyposis, 130 of whom had ASA intolerance. After polypectomy the controls received no further medical treatment. Patients were examined every 3 months and radiographs of the paranasal sinuses were obtained every 6 months. After 24 months 34 of 43 patients (79.1%) treated with topical LAS had suffered no relapse of polyposis. Only 45 of 191 control patients (23.6%) failed to relapse after 24 months (P less than .0001). Nine of 28 (32.1%) ASA-intolerant patients treated with LAS and 105 of the 130 (80.77%) control subjects relapsed (P less than .0001). None of the 15 ASA-tolerant patients treated with LAS relapsed, but 41 of the 61 (67.21%) nontreated control subjects relapsed (P less than .00001). These data indicate topical LAS is effective in preventing recurrence of nasal polyps after polypectomy.

[Topical intranasal cortisone therapy].

Owing to improvements made during the last 15 years in the pathophysiological and pharmacological research, many new corticosteroids have been successfully experimented. They have high activity on the target organ and they are suitable for long term therapies since they have not any systemic and/or local side effects. Nowadays the topical intranasal corticosteroid therapy is indispensable for allergic rhinitis treatment and it is very useful for many nasal and bronchopulmonary diseases (some chronic rhinitis, nasal polyposis, bronchial asthma, chronic obstructive bronchopulmonary diseases). The authors use their personal experience and carefully review the literature to describe the general aspects (pharmacology, pharmacokinetics, toxicology, side effects and contraindications) and to analyze the single drugs currently used in Italy and abroad. Finally, they compare the efficacy of each topical intranasal glucocorticoid among themselves and with other drugs.

Immunopathology of nasal polyps: an immunohistochemical approach.

We studied the mast cells and the T-lymphocyte subpopulations of four patients' nasal polyps using immunohistochemical procedures. The data showed that MC displayed IL2-receptor and that they were very often closely related to CD4+ and MHC class II-positive T-lymphocytes. CD8-positive T-cells represented only 10% to 15% of the whole lymphoid population and were not localized near mast cells. These findings suggest a possible role of cell-mediated immune reactions in the pathogenesis of nasal polyps.

A double-blind group comparative study of nedocromil sodium in the treatment of seasonal allergic rhinitis.

Thirty-eight patients with seasonal rhinitis due to grass pollen allergy took part in this double-blind study comparing 1% nedocromil sodium and placebo. Treatment was allocated by randomised coding sheet and consisted of 1% nedocromil sodium nasal spray or placebo given four times daily for four weeks during the peak pollen season. Highly significant (p less than 0.001) differences in favour of nedocromil sodium were seen for all signs and symptoms recorded at clinical assessments, and for diary card assessments of symptoms. In addition, time to effect and patient and clinician opinions of treatment significantly (p less than 0.001) favoured nedocromil sodium. Laboratory data on blood and urine samples taken before and after treatment showed no significant effects, and both treatments were well tolerated. Nedocromil sodium 1% nasal spray taken four times daily was shown to be an effective treatment for grass pollen rhinitis.

[Therapy of allergic rhinitis in childhood].

Allergic rhinitis is the most common of all allergic disorders. After summarising the clinical features and diagnostic approach with regard to differential diagnosis, we will discuss the therapeutic modalities. As with all long-term therapy measures, it is essential to persuade both the child and the parents to participate in the treatment and to get their co-operation.

Serum immunoglobulins and secretory IgA deficiency in tonsillectomized children.

We studied serum immunoglobulin patterns in 65 children aged 2 to 10 years before and 1 to 4 months after tonsillectomy and adenoidectomy, and secretory IgA (sIgA) levels in 46 children aged 3 to 10 years before and 1 month after the same operation. Serum immunoglobulin and sIgA values were normal prior to surgery, and significantly lower afterwards. The data emphasize the importance of palatine tonsils not only in the synthesis of monomeric immunoglobulins but also in the synthesis of dimeric immunoglobulins in secretions. Although more long-term, follow-up studies supporting our results are needed, we suggest that a post-adenotonsillectomy drop in immunoglobulin and sIgA levels may predispose children to a constellation of disorders. We recommend, therefore, that serum immunoglobulins and sIgA levels be determined in all children before and after surgery.

Seven hereditary syndromes with pigmentary retinopathy. A review and differential diagnosis.

This article reviews several autosomal recessive syndromes characterized by pigmentary retinopathy and, in many, combined with deafness, hypogonadism, and/or mental retardation. These syndromes are manifested in infancy and childhood. Although no specific treatment is available, an early diagnosis can be the first step in initiating symptomative management and preventive measures for the patient and family.
