A comparative, cross-over trial was conducted to determine patient preference for the slow release potassium supplements Slow K and Leo K. Fifty-seven patients took part in the trial and the majority found Leo K preferable to Slow K, principally because Leo K was easier to swallow and caused fewer side-effects. In order to increase the chances of patients following the prescriber's instructions it would seem logical to prescribe Leo K rather than Slow K on the basis of patient preference.

BACKGROUNDTreatment of ulcerative colitis or Crohn’s disease with sulphasalazine causes several adverse effects, including hepatitis. Sulphasalazine is cleaved by colonic bacteria into 5-aminosalicylic acid and sulphapyridine. Received wisdom was that 5-aminosalicylic acid was topically active, whereas sulphapyridine was absorbed and caused immunoallergic side effects. Mesalazine, a slow release formulation of 5-aminosalicylic acid, was expected to be a safe alternative. However, several cases of acute hepatitis have been reported.CASE REPORTA 65 year old man had increased liver enzymes, anti-nuclear and anti-smooth muscle autoantibodies and IgG levels, and lesions of chronic hepatitis after 21 months of mesalazine treatment. Although liver dysfunction had been identified eight months earlier, simvastatin rather than mesalazine had been withdrawn, without any improvement. In contrast, liver enzyme and IgG levels became normal and autoantibodies disappeared after discontinuation of mesalazine administration.CONCLUSIONContrary to initial expectations, mesalazine can cause most of the sulphasalazine induced adverse effects, and hepatic side effects may be almost as frequent. When liver dysfunction occurs, mesalazine administration should be discontinued to avoid the development of chronic hepatitis and liver fibrosis.

Depressive States

Patients suffering from mixed anxiety/depressive states referred to a psychiatric out-patient clinic completed a four week course of either a once-daily tablet of 30 mg nortriptyline with 1· 5 mg fluphenazine, or a sustained release capsule of 50 mg amitriptyline once daily, on a double-blind basis. Depression improved satisfactorily on either treatment, but there was a greater reduction of anxiety on fluphenazine/nortriptyline. Drowsiness, however, occurred more frequently among the patients on amitriptyline, suggesting the sedative properties of this drug did not substitute adequately for a specific anxiolytic effect. Dry mouth was also noticeably more frequent with amitriptyline. As might be expected on pharmacokinetic and physiological grounds, the results suggest that the sustained release characteristics of the amitriptyline preparation lead to a maximization of side-effects during the day without conferring any therapeutic advantage.

Antihypertensive Drug Therapy

AbstractRenal denervation is a potential alternative to antihypertensive drug therapy. However, data on patient preference for this treatment option are limited and there are no data specifically from Asian patients. This study evaluated patient preference for renal denervation in patients with hypertension from Japan. Patients were a subset of those who participated in a March 2020 online electronic survey of patients with hypertension who had regularly visited medical institutions for treatment, were receiving antihypertensive drug therapy and had home blood pressure recordings available. The survey included a question about patient preference for treatment with renal denervation. A total of 2,392 patients were included (66% male, mean age 59.8 ± 11.6 years, mean duration of hypertension 11.4 ± 9.5 years). Preference for renal denervation was expressed by 755 patients (31.6%), and was higher in males than in females, in younger compared with older patients, in those with higher versus lower blood pressure, in patients who were less adherent versus more adherent to antihypertensive drug therapy, and in those who did rather than did not have antihypertensive drug-related side effects. Significant predictors of preference for renal denervation on logistic regression analysis were younger patient age, male sex, higher home or office systolic blood pressure, poor antihypertensive drug adherence, the presence of heart failure, and the presence of side effects during treatment with antihypertensive drugs. Overall, a relevant proportion of Japanese patients with hypertension expressed a preference for renal denervation. This should be taken into account when making shared decisions about antihypertensive drug therapy.

Previous studies from our laboratory revealed no effect of aspirin on plasma βTG levels in healthy volunteers as well as in patients with cerebrovascular accident. This double blind study was undertaken to investigate the effect of prolonged administration of Persantin. Two groups of 10 volunteers each received 4×100 mg Persantin or 2×200 mg daily in slow release form for 21 days. Platelet studies were performed prior to- and once every week during the trial. The volunteers refrained from smoking and were not on oral contraceptives or other drugs. No effect was observed on ADP (1 μ M f.c.) or collagen induced aggregation. All βTG plasma levels were within normal limits i.e. below 60/ml of plasma. No tendency of decreasing levels was observed. Side effects were significantly more observed in the volunteers on slow release Persantin (Mean Whitney Test α < 0.025). Side effects included sensations of a dry mouth and thirst, headache and di2Lzyness.

Balancing recurrence risk, side effects and patient preference in the treatment of multiple metachronous testicular tumours can be challenging. We present the case of a young male patient who developed 3 different primary testicular neoplasms over an 8-year period, each associated with retroperitoneal lymphadenopathy requiring chemotherapy. The first tumour at age 19 was managed with radical orchiectomy. Four years later, a partial orchiectomy was performed to remove 2 small lesions. Another 4 years later, a complete orchiectomy was required for an additional tumour. This case highlights the caveats of testis-sparing surgery for testis cancer and the need for careful surveillance in these patients.

Children With Asthma

To evaluate the long-term effects of slow-release formulations of theophylline and terbutaline on pulmonary function, clinical symptoms, and side effects, 24 children with stable and moderately severe perennial asthma participated in a prospective double-blind crossover study. The patients and the treatments were randomized according to the Latin square design to eliminate all possible period/climate biases throughout the protracted study period. The treatments consisted of terbutaline, 5 mg, theophylline, 200 mg, the combination, and placebo, given twice daily orally and crossing over every 28 days. The two drugs, administered alone or in combination, improved lung function and symptoms when compared with placebo. The interaction of theophylline and terbutaline was quantitatively shown by 2 x 2 factorial statistical design to be essentially additive rather than synergistic in the control of asthma. No increase in side effects was noted when the combined therapy was used. These findings suggest therapeutic advantages to combining submaximal oral doses of sustained-release theophylline and terbutaline for the long-term treatment of children with asthma.

Slow Release Formulation

Somatostatin analogs have been shown to be effective for the treatment of TSH-secreting pituitary adenomas. However, their use in this indication is limited by the fact that available analogs require several daily sc injections. The present study was performed to evaluate the effects of a slow release formulation of the somatostatin analog lanreotide (SR-L) on both hormone secretion and tumor size and to assess the tolerance in a series of thyrotropinomas treated for 6 months. Eighteen patients with hyperthyroidism related to a TSH-secreting pituitary adenoma, evidenced by pituitary magnetic resonance imaging, were studied. After a basal assessment, each patient received 30 mg SR-L, im, every 14 days for 1 month. Then, according to the free T3 (fT3) plasma level measured, 9 of 18 patients were injected twice monthly, and 7 of 18 patients received SR-L every 10 days for 5 additional months. One patient was dismissed from the study in month 1 of the study for side-effects and another in month 3 for noncompliance to the protocol. Clinical and biological evaluations (plasma TSH, free α-subunit, fT4, fT3, and lanreotide levels) were performed before and in months 1, 3, and 6 of treatment. Pituitary magnetic resonance imaging and gallbladder ultrasonography were performed both at entry and at the end of the study. Clinical signs of hyperthyroidism improved within 1 month in all 16 evaluable patients. Mean (±sem) plasma lanreotide levels reached 1.11 ± 0.43 and 1.69 ± 0.65 ng/mL in month 3 using 2 and 3 injections/month, respectively, then remained stable until the end of the study. During therapy, the plasma TSH level decreased from 2.72 ± 0.32 to 1.89 ± 0.27 mU/L (P &lt; 0.01), with parallel significant changes in free α-subunit. During the same period, plasma fT4 and fT3 levels decreased from 37.9 ± 2.9 to 19.7 ± 2.3 pmol/L (P &lt; 0.01) and from 14.6 ± 1.1 to 8.3 ± 0.8 pmol/L (P &lt; 0.01), respectively. No statistically significant change in mean adenoma size was observed after 6 months of treatment. Side-effects, including pain at the injection point, abdominal cramps, and diarrhea, were mild and transient and did not lead to interruption of the treatment. No gallstones occurred during the study. SR-L appears to be able to suppress clinical signs of hyperthyroidism in our series of patients with TSH-secreting pituitary adenomas. The analog also reduces plasma TSH and thyroid hormone levels, which were normalized in 13 of 16 cases. The effect was maintained throughout the treatment using 2 or 3 SR-L injections monthly without any problem of tolerance. We conclude that SR-L is a safe and effective treatment of thyrotropinomas and avoids the drawbacks of the modes of administration of other somatostatin analogs, given three times daily.
