[Long term treatment of moderate to severe hypercholesterolemia with low dose statin. Comparison of simvastatin and pravastatin]. / Trattamento a lungo termine dell'ipercolesterolemia di grado moderato-severo con statine a picole dosi. Comparazione tra simvastatina e pravastatina.

Sixty-seven subjects with primary hypercholesterolemia were enrolled in an open study with "low dosages" of inhibitors of 3-hydroxy-3methylglutaril coenzyme A reductase. Patients were randomized in comparative and parallel study with simvastatin 10 mg (30 subjects) and pravastatin 20 mg (27 subjects) once in the evening for a treatment period of 12 months. At the end of the treatment the plasma concentrations of total and LDL cholesterol were reduced respectively by 21% (p < 0.001) and 29% (p < 0.001), plasma triglyceride concentration was reduced by 16%, high density lipoprotein (HDL) was increased by 2.9%. The efficacy of drugs was increasing during the study: at the third month 63% of subjects and at the twelfth month 89% of subjects showed a LDL < 160 mg/dL. In this study the drugs were well-tolerated, but 11 subjects showed a slight and transitory increase of CK. A treated group with simvastatin showed a similar decrease of the total cholesterol and LDL as that one treated with pravastatin. Pravastatin in comparison with simvastatin reduced significantly plasma triglycerides. There was no significant difference between the groups in the frequency of drug-related adverse effects. In conclusion "low dosages" of simvastatin and pravastatin in long term treatment were very efficacious in the reduction of total and LDL cholesterol. In our study, the decrease of total and LDL cholesterol was time-dependent, with the greatest reduction after sixth months. There were no significant differences between 10 mg of simvastatin and 20 mg of pravastatin on reduction of total and LDL cholesterol levels. Triglycerides decreased significantly only with pravastatin.

[Arterial hypertension induced by an excess of mineralocorticoids caused by abuse of nasal spray. Report of a case]. / Ipertensione arteriosa da eccesso di mineralcorticoidi dovuta ad abuso di spray nasale. Descrizione di un caso.

Among the various syndromes caused by excess mineralocorticoids, the factitious syndrome produced by excessive 9-alpha-fluorprednisolone inhalations is more common than might be expected, especially in places where the drug is easily obtained without a doctor's prescription. A fairly typical case of addiction to a nasal spray containing ephedrine hydrochloride and an imidazoline compound as well as the steroid is described. The diagnosis of the case is analysed with details of certain differences from similar cases reported in the literature and the modifications to clinical and instrumental parameters achieved after over two months' treatment with spironolactone are described.
