Symptoms can markedly influence the hemodialysis patients well-being and quality of life. The aim of this paper is to study the frequency of symptoms at home and how these relate to biochemical and treatment variables. Seventy-three hemodialysis patients were questioned on the absence, occasional presence or daily recurrence (score = 0, 1, 2) of 14 symptoms and a record was made of their biochemical parameters, age, time on treatment and KtIV as a function of each symptom. The following relationships were detected: thirst with high Osm and BUN; asthenia with old age and hypoalbuminemia; insomnia with hypercalcemia; hypersomnia with hypoxemia and hypernatremia; anorexia with hypokalemia; dyspnea with old age, hypernatremia and hypokalemia; dysgeusia with hypoxemia; nausea with alkalemia, hypoxemia and low BUN; vomiting with alkalemia. Pruritus, arthralgia, restless legs syndrome, cramp and tremor showed no relationships. Monitoring acid-base balance and plasma electrolytes could help to alleviate symptoms and ameliorate quality of life of hemodialysis patients.

Amplification of the human epidermal growth factor receptor 2 protein (HER2) in primary breast carcinomas has been shown to correlate with poor clinical prognosis for certain patients. Trastuzumab (Herceptin, Genentech, Inc., South San Francisco, California) is a highly purified recombinant DNA-derived humanized monoclonal immunoglobulin G1 kappa antibody that binds with high affinity and specificity to the extracellular domain of the HER2 receptor. In vitro and in vivo preclinical studies have shown that administration of trastuzumab alone or in combination with paclitaxel or carboplatin significantly inhibits the growth of breast tumor-derived cell lines that overexpress the HER2 gene product. At therapeutic doses in breast cancer patients, the mean half-life of trastuzumab is 5.8 days. Trastuzumab serum concentrations reach steady state with mean trough and peak concentrations of 79 microg/mL and 123 microg/mL, respectively. In a 222-patient, single-arm clinical study, treatment with a loading dose of trastuzumab 4 mg/kg administered IV followed by weekly IV doses of 2 mg/kg produced an overall response rate of 14% (2% complete remission and 12% partial remission). The beneficial effects were greatest in patients with the greatest degree (3+) of HER2 protein overexpression. In another clinical study, 469 women with metastatic breast carcinoma were randomized to a paclitaxel or anthracycline-plus-cyclophosphamide regimen with or without trastuzumab. The overall response rate was significantly greater in the trastuzumab-plus-chemotherapy group than in the chemotherapy-alone cohort. The magnitude of observed effects was greatest with pacli taxel plus trastuzumab. The most common adverse effects attributed to trastuzumab in clinical studies were fever and chills, pain, asthenia, nausea, vomiting, increased cough, diarrhea, headache, dyspnea, infection, rhinitis, and insomnia. Trastuzumab in combination with chemotherapy can lead to cardiotoxicity, leukopenia, anemia, diarrhea, abdominal pain, and infection. Trastuzumab has been approved by the US Food and Drug Administration as a single agent for the treatment of patients who have metastatic breast cancer involving overexpression of the HER2 protein and who have received 1 or more chemotherapy regimens; in combination with paclitaxel, it has been approved for the treatment of such patients who have not received chemotherapy.

In order to clarify the later sequelae of sarin poisoning that occurred in Matsumoto City, Japan, on June 27, 1994, a cohort study was conducted on all persons (2052 Japanese people) inhabiting an area 1050 meters from north to south and 850 meters from east to west with the sarin release site in the center. Respondents numbered 1237 and 836 people when surveys were conducted at one and three years after the sarin incident, respectively. Numbers of persons with symptoms of sarin toxicity were compared between sarin victims and non-victims. Of the respondents, 58 and 46 people had symptoms associated with sarin such as fatigue, asthenia, shoulder stiffness, asthenopia and blurred vision at both points of the survey, respectively. The prevalences were low; some complained of insomnia, had bad dreams, difficulty in smoking, husky voice, slight fever and palpitation. The victims who had symptoms one year after the incident had a lower erythrocyte cholinesterase activity than did those who did not have symptoms at the early stage; such persons lived in an area with a 500 meter long axis north east from the sarin release site. The three-year cohort study clearly showed that the odds ratios of almost all of the symptoms were high in the sarin-exposed group, suggesting a positive relationship between symptoms and grades of exposure to sarin. These results suggest that symptoms reported by many victims of the sarin incident are thought to be sequelae related to sarin exposure.

Historically, the emphasis in treating depression has been focused on the acute phase of treatment, with few published data on the continuation and maintenance phases of treatment. Yet the risk of depression increases with each episode, with a 50% to 90% chance of developing another episode after 1 or 2 prior episodes of depression. Moreover, subsequent episodes of depression are often of longer duration, more severe, and less responsive to treatment. Most patients with major depression require some form of long-term antidepressant treatment, and many need lifelong treatment. Optimizing efficacy and minimizing side effects are essential during both the acute and long-term phases of antidepressant treatment. Antidepressant side effects, including insomnia or somnolence, weight gain, asthenia, and sexual dysfunction, can significantly decrease patient compliance with long-term treatment for depression. Identification and management of side effects, combined with early and ongoing educational messages to the patient about treatment issues and the importance of sustaining illness remission, help improve compliance and reduce the potential for premature discontinuation of an otherwise optimal antidepressant.

At present only two drugs are approved for long-term treatment of obesity. Sibutramine inhibits the reuptake of serotonin and norepinephrine. In clinical trials it produces a dose-dependent 5-10% decrease in body weight. Its side effects include dry mouth, insomnia, asthenia, and constipation. In addition, sibutramine produces a small increase in blood pressure and pulse that is a contraindication to the use of this drug in some individuals with heart disease. Xenical is the other drug approved for long-term use in the treatment of obesity. It works by blocking lipase and thus increasing the fecal loss of triglyceride. One valuable consequence of this mechanism of action is the reduction of serum cholesterol that averages about 5% more than can be accounted for by weight loss alone. In clinical trials it produces a 5-10% loss of weight. Its side effects are entirely due to undigested fat in the intestine that can lead to increased frequency and change in the character of stools. It can also lower fat-soluble vitamins. The ingestion of a vitamin supplement before bedtime is a reasonable treatment strategy. The effect on weight loss during long-term trials with these two drugs is shown in Figs 7 and 8 above. Also in this figure is data on phentermine used in trials of six months or more. Although there were differences in mean weight losses with these drugs, when the placebo effect was taken into account they all had a surprisingly similar magnitude of weight loss.

Cetirizine is the carboxylated metabolite of hydroxyzine, and has high specific affinity for histamine H(1) receptors. Pseudoephedrine is a sympathomimetic drug that acts directly on alpha-adrenergic receptors. black triangle Cetirizine/pseudoephedrine 5/120 mg twice daily was significantly more effective than intranasal budesonide 100 microg or placebo at improving nasal obstruction, nasal patency and reducing the volume of nasal secretion, and was significantly more effective than intranasal xylometazoline 0.1% with respect to nasal secretion, during house dust mite faeces challenge in three randomised, cross- over studies among volunteers with seasonal or perennial rhinitis. The onset of action of cetirizine/pseudoephedrine was reported to be approximately 30 minutes. black triangle The bioavailability of cetirizine and pseudoephedrine is similar after administration of cetirizine/pseudoephedrine 5/120 mg bilayer tablets or coadministration of cetirizine 5 mg tablets plus pseudoephedrine sustained-release (SR) 120 mg caplets. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was significantly more effective than each drug given alone at reducing mean total symptom scores for seasonal or perennial allergic rhinitis in two randomised, double-blind, multicentre trials. In both studies, the mean proportion of days during which the five measured symptoms (nasal obstruction, sneezing, rhinorrhoea, nasal pruritus and ocular pruritus) were absent or mild was significantly greater in recipients of the cetirizine plus pseudoephedrine SR. black triangle In one study, cetirizine 5 mg plus pseudoephedrine SR 120 mg was significantly more effective at reducing nasal obstruction than either drug alone. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was well tolerated in patients with seasonal or perennial allergic rhinitis. The most common adverse events were dry mouth, insomnia, headache, somnolence, asthenia and nervousness.

Second generation antiepileptics lamotrigine (LTG) and tiagabine (TGB) were primarily licensed for adjunctive treatment of simple and complex partial seizures with/without secondary generalisation as similarly effective drugs. Reduction of seizures frequency is the most important index of drug efficacy, but overall therapeutic benefit estimated as a quality of life is nowadays the target goal of management. In this study efficacy and tolerability of LTG or TGB as short-term add-on treatment in patients with refractory complex partial seizures were assessed by the use of both physician-rated measures (mean monthly seizure frequency, responders rate, adverse events, clinical biochemistry) and patients perceived change in their own quality of life estimation (descriptive scale and visual analogue scale-VAS). Comparable efficacy of LTG (n-22, 378 mg/day) and TGB (n-26, 43 mg/g) was assessed as 41 and 35% of responders and above half of patients with noticeable improvement. 25% of patients in both groups reported reduction of seizures severity in 4-points descriptive scale. Biochemistry values did not show clinically significant changes after treatment. 13% of patients on LTG reported adverse events (headache, asthenia, irritability, insomnia). This coefficient was greater for TGB-35% (asthenia, headache, sleepiness, vertigo). However, no case of discontinuation as a result of adverse events was reported for either of the tested drugs. Even if efficacy of LTG and TGB was comparable in objective measurements, only patients on LTG reported a significant quality of life improvement in VAS. This might be the consequence of more frequent adverse events and treatment schedule of TGB (triple dosing/day). This trial confirmed that VAS might be used as an easy additional test in evaluation of antiepileptic drug for individual patient in everyday clinical practice.

Lamotrigine (LTG) as both effective against a wide range of seizure types and epileptic syndromes and well tolerated drug is being used in mono--as well as in polytherapy of pharmacoresistant epilepsy. The aim of this study was to evaluate the efficacy, safety and neuropsychological functioning after LTG (mean daily dose: 316 mg) as long-term monotherapy (12 mo) in 24 young adult out-patients (22.5 ys) with newly recognised and not-previously treated epilepsy in an open, non-comparative trial. 67% of patients were responders (above 50% reduction in seizure frequency) and 42% reported seizures remission. The best were results in patients with generalised convulsive fits (87% with remission). Adverse events in the early phase of medication in 21% of patients typically concerned CNS and gastrointestinal system (headache, asthenia, insomnia, nausea, gastric aches) and resolved spontaneously without treatment discontinuation. Biochemical examinations were normal and transient leucopenia and diminishion of MCV were clinically not significant. Neurodynamic abilities, neuropsychological examination results, memory verbal and visual tests and organic evaluation in organic triada tests did not show deterioration after LTG treatment. Slight difficulties in abstractive and operative thinking and some focal symptoms of fronto-temporal origin should be considered a result of drug but also the epilepsy per se. No significant differences in latencies and amplitudes of evoked potentials (VEP, BAEP, SEP and especially ERP-300) were measured after LTG. Preliminary results obtained in this study supported good efficacy and tolerability and especially lack of unfavourable influence of LTG on neuropsychological functioning in young previously untreated patients with epilepsy.

The tolerability and safety of donepezil HCI in patients with mild to moderate Alzheimer's disease (AD) were examined in an integrated analysis of phase II/III placebo-controlled trials. Patients with mild to moderately severe AD (n=1,920) were randomised to receive donepezil (n=1,291) or placebo (n=629). Adverse events, physical examinations and clinical laboratory tests were assessed. A high completion rate (79%) was achieved in these trials. Of the 1,291 patients receiving donepezil only, 142 (11%) withdrew because of an adverse event compared with 43 of the 629 (7%) placebo patients. The most common adverse events included nausea, diarrhoea, headache, insomnia, dizziness, rhinitis, vomiting, asthenia/fatigue and anorexia. Donepezil had no clinically significant effect on any laboratory evaluations and was not associated with hepatotoxicity. These results demonstrate that donepezil is well tolerated and has a favourable safety profile at clinically effective, once-daily doses of 5 mg and 10 mg.

The main mechanisms of the chronopathological forms of magnesium depletion associate a low Mg intake with various dysregulating biorhythms. The differentiation between forms with hyperfunction and forms with hypofunction of the biological clock is seminal and the main marker is the production of melatonin (MT). The clinical forms of the various patterns of the chronopathological forms of Mg depletion may be central or peripheral. The clinical forms with hyperfunction of the biological clock (marker: increase in MT) may associate diverse expressions of nervous hypoexcitability: depression (i.e. Seasonal affective disease); cephalalgias nocturnal, without photophobia (i.e. cluster headaches); dyssomnia LASPS (advanced sleep phase syndrome) particularly]; asthenia and myalgias (i.e. fibromyalgia, chronic fatigue syndrome). The main comorbidity is found with depressive states. The therapy relies on classical bright light phototherapy, sometimes associated with psychoanaleptics. The clinical forms with hypofunction of biological clock (marker: decrease in MT) may associate various signs of nervous hyperexcitability (HEN): anxiety (from generalized anxiety to panic attacks); cephalalgias diurnal with photophobia (mainly migraine); dyssomnia [DSPS (delayed sleep phase syndrome) particularly, jet lag, night work disorders, age related insomnia, sometimes with inappropriate behaviour; photogenic epilepsia, generalized or focal; some clinical forms of chronic fatigue syndrome and fibromyalgia. The main comorbidity is between migraine and epilepsia. The treatment relies on the diverse forms of darkness therapy, possibly with the help of some psycholeptics: anxiolytics and anticonvulsants. The indications of chromatotherapy remain to be validated.
