Twenty-four patients with reversible airflow obstruction under suboptimal control on conventional therapy entered a double-blind placebo-controlled trial of additional oral sustained release aminophylline. Assessment was by diary cards, twice daily PEFR, and weekly FEV1. Nineteen patients completed the trial satisfactorily. Eleven were improved subjectively by addition of aminophylline. The mean PEFR for all 19 patients rose from 232 1 min-1 SEM +/- 5, to 247 1 min-1 SEM +/- 4 (p less than 0.0001); nine individuals showed a statistically significant improvement in mean PEFR and 10 showed an improvement of greater than 200 ml in their FEV1. Improvement in PEFR on aminophylline was not at the expense of benefit from inhaled salbutamol. Unwanted effects of nausea, headache, and abdominal discomfort were recorded by 12 of the 24 patients entering the trial. Seventeen of the 19 patients completing the trial had plasma theophylline levels in the accepted therapeutic range of 10-20 mg 1(-1). The drug doses required to achieve these levels varied from 8.6-30.8 mg kg-1 24 hr-1 in the patients with no clinical or biochemical evidence of liver disease. Oral aminophylline can improve control of airflow obstruction in patients with moderately severe disease who are already receiving multiple medication, but side-effects often limit its use. The wide dose range required to achieve therapeutic plasma levels indicates that measurements of plasma theophylline are necessary for adequate interpretation of trials of theophylline compounds.

1 Fifty infusions of epoprostenol (PGI2) were made, usually increasing the infusion rate until adverse effects were encountered. The volunteers were appraised that they might experience headache and facial flushing. 2 Facial flushing, headache, tachycardia and decrease in diastolic blood pressure were seen in almost all subjects. Erythema over the venous infusing site was also encountered in 13 infusions. Less common effects were sudden bradycardia, pallor and sweating--the vagal reflex--(seven times) and chest pain (twice). Other complaints included restlessness, abdominal discomfort, nausea and drowsiness. 3 The literature on side effects reported during PGI2 infusion is reviewed and recommendations are made concerning administration of PGI2.

A survey of gastrointestinal symptoms was performed on 109 male lead workers in a battery manufacturing factory six months after the start of its operation. Prevalence of gastrointestinal symptoms was analysed in relation to levels of lead absorption and other relevant factors including occupational history, work shift, smoking habits, alcohol intake, frequency of meals a day, housing and sleeping hours. Subjects who had experienced gastrointestinal diseases shortly before employment were excluded. Age, blood lead and urinary delta-ALA concentration of this population were 34.3 +/- 10.3 years, 30.9 +/- 13.6 micrograms/100 ml and 2.74 +/- 1.64 mg/l (Mean +/- S.D.), respectively. Mean blood lead and urinary delta-ALA concentrations of the subjects who complained loss of appetite were significantly higher than those who did not. However, there were no significant differences in the blood lead concentration between subjects who responded yes or no to other gastrointestinal symptoms. Of the 109 male workers, 49 (45.0%) complained at least one of the five gastrointestinal symptoms (nausea, abdominal discomfort, belching, heart burn and hunger pain) which are suspected to be associated with peptic ulcer. When the subjects complaining such symptoms were compared with the rest of the workers, there were no significant differences in blood lead, urinary delta-ALA, urinary coproporphyrin, smoking habits, alcohol intake, frequency of meals a day and housing. Means of age and sleeping hours on day-work were lower and proportions of the workers who were on shift duty at the time of the survey and who had not previously experienced shift work were higher in the subjects who complained such symptoms than in those who did not. It was suggested by these results that considerably high prevalences of the most of the symptoms in lead-exposed workers had been induced by the shift work or the change of jobs, although it was also suggested that the loss of appetite might have been related to lead exposure.

The stools of 35 patients with S. intercalatum bilharziasis are examined 48 hours, 45 days and 6 months after treatment, using praziquantel, a new trematodicide drug, in an individual single dose of 40 mg/kg body weight. The number of eggs per gram of faeces is not significantly reduced 2 days after treatment. After 45 days however eggs are only to be found in the stool of one patient among the 25 treated persons who were seen for control. Six months later 23 persons were examined again and 3 stools specimens were found positive, this being possibly due to reinfection. The drug has been well tolerated, except for minor side effects such as headache, nausea and abdominal discomfort.

Sixteen patients on regular hemodialysis were treated with clofibrate, 500 mg three times a week for six weeks. A sustained and significant reduction of serum triglycerides occurred in thirteen patients. Serum cholesterol was also significantly reduced, although to a lesser degree. Predialysis levels of blood urea nitrogen, creatinine, and uric acid were significantly elevated during the treatment period and returned to previous levels after withdrawal of the drug. The incidence of side-effects was elevated. Five patients complained of nausea and upper abdominal discomfort, while four patients had muscle pain. Several muscle enzymes were elevated in a high percentage of patients, returning to basal values after discontinuation of the drug. It is concluded that clofibrate, although it is effective in lowering serum triglycerides in patients on hemodialysis, should not be used in such patients.

Intraperitoneal (IP) administration of fluorinated pyrimidines has been evaluated for ovarian and gastrointestinal malignancies in phase I, II, and III trials. The tolerance and pharmacokinetic profile of IP 5-fluoro-2'-deoxyuridine(FUDR) alone and with (R,S)-leucovorin ((R,S)-LV) have each been evaluated in previous phase I studies. FUDR doses of 3 g per day with and without (R,S)-LV doses up to 640 mg per day given IP are well tolerated. The current phase I study was designed to determine the pharmacokinetic profiles and clinical tolerance of escalating doses of the pure biologically active S-isomer of leucovorin ((S)-LV) given IP with the same dosing schedule of FUDR. A group of 16 patients with disease confined to the abdominal cavity were treated in this study. Pharmacokinetic studies of blood and peritoneal fluid, toxicity profiles, and clinical response for the first three cycles are reported here. The toxicity profile did not significantly differ from the prior two studies. All non-hematologic toxicities, such as fatigue, nausea, vomiting, diarrhea, and abdominal discomfort were less than grade 4, and most were less than grade 3. Neutropenia and thrombocytopenia were uncommon and observed only in patients with compromised bone marrow reserve. The pharmacokinetic profiles were also congruent with the previous studies and indicate a three-log advantage for FUDR. The (S)-LV profiles in the peritoneal cavity paralleled those of FUDR. Antitumor effects or absence of progression until after cessation of therapy were documented in 11 patients. At a median follow-up of 18 months 44% of patients were alive. IP administration of 3-g of FUDR and up to 640 mg (S)-LV daily for three days was well tolerated. The tolerance and antitumor effects observed during IP FUDR and LV in these studies encourage further exploration of this regimen against ovarian and gastrointestinal malignancies. The actual role and optimal dose of LV as an enhancer of the antitumor actions of FUDR administered by this route remain unknown.

Valproic acid is a branched-chained fatty acid, structurally unrelated to any other antiepileptic drug. Since publication of the original review in the Journal in 1977, several clinical trials have documented its efficacy and safety in adults and children for the treatment of generalised seizures (absence, tonic-clonic, myoclonic), partial seizures (simple, complex, secondarily generalised) and compound/combination seizures (including those refractory to treatment with other antiepileptic drugs). Valproic acid monotherapy has demonstrated efficacy equivalent to that of carbamazepine, phenytoin, and phenobarbital in the treatment of both generalised and partial seizures and ethosuximide in the treatment of absence seizures. Adverse effects associated with the drug are primarily gastrointestinal (nausea, vomiting, dyspepsia) in nature, although the use of enteric-coated formulations has reduced the incidence of abdominal discomfort. Weight gain, tremor and transient hair loss are commonly reported. Importantly, valproic acid has minimal neurological adverse effects (sedation, ataxia, impairment of cognitive function) compared with other antiepileptic drugs, a finding that may be of particular relevance in many patients with epilepsy. The incidence of rare, fatal liver failure has been greatly reduced by identifying and avoiding administration of valproic acid to high risk patient populations. An estimated risk of 1 to 2% for neural tube defects, predominantly spina bifida aperta, with maternal use of valproic acid therapy has been reported. Valproic acid inhibits hepatic drug metabolism and displaces other highly bound drugs from their plasma protein binding sites. Therefore, coadministered drugs which are highly protein bound or hepatically metabolised may require dosage adjustment. Enzyme-inducing antiepileptic drugs may increase valproic acid metabolism and necessitate increasing its dosage. Thus, comparative trials and extensive clinical experience have demonstrated the efficacy and tolerability of valproic acid and support its role as a valuable and well established first-line treatment for patients with a broad range of seizure types.

Bisphosphonates are analogues of inorganic pyrophosphate, a naturally occurring chemical in bone. In vitro and animal experiments demonstrated that these agents were effective inhibitors of bone resorption. Subsequently they were applied to a variety of clinical problems in which increased bone resorption was an underlying feature of the pathology. In 1971 etidronate became the first bisphosphonate shown to inhibit bone resorption in humans when it was given to patients with Paget's disease. Subsequently this agent was also found to be useful in treating the hypercalcemia of malignancy. At the present time cyclic etidronate therapy is also used for the prevention of bone loss in patients with osteoporosis and for the prevention of heterotopic ossification in spinal cord-injured patients and in patients after hip replacement. Newer bisphosphonates are generally more potent than etidronate and do not produce a severe mineralization defect as do higher doses of etidronate. Pamidronate and clodronate are highly effective in the management of Paget's disease, hypercalcemia due to malignancy and immobilization, metastatic bone disease, and hematologic malignancies affecting bone. They are also promising agents for the prevention of osteoporosis. Alendronate, risedronate, and CGP 42446 are highly potent bisphosphonates that look very promising for the treatment of all disorders of bone resorption. It is fortunate that adverse reactions are not a prominent feature of bisphosphonate use. The main side effects are nausea and abdominal discomfort, mainly with oral use, a transient increase in bone pain in patients with Paget's disease, and an acute-phase reaction (fever, myalgia, mild leukopenia) in patients receiving aminobisphosphonates. The evolution of bisphosphonate therapy should be considered one of the major therapeutic events of the past 25 years. Future research should define the optimum use of these agents.

One hundred and three acromegalic patients from 14 medical centers were enrolled in this study to determine the efficacy and safety of the somatostatin analog, octreotide acetate, during long term treatment. Seventy percent of the patients had undergone previous surgery or radiation treatment. Octreotide was initiated at a dose of 100 micrograms, sc, every 8 h and gradually increased to a maximum of 1500 micrograms daily depending upon the individual patient's clinical and biochemical response [GH and insulin-like growth factor I (IGF-I) reduction]. The mean duration of treatment was 24 months (range, 3-30 months). However, most patients were treated for a mean of 30 months, because this study took place after an initial 6-month study previously reported. Mean serum GH fell from 30.9 micrograms/L (range, 2.7-350) to 5.7 micrograms/L (range, 0.6-59) at the 3 months visit and remained suppressed (P < 0.001). Plasma IGF-I concentrations were also significantly reduced and remained in the normal range for at least half of the treatment visits in 56 of 87 patients (64%) treated for 12-30 months. Patients with higher initial GH concentrations were less likely to normalize IGF-I concentrations during treatment (P < 0.001). There was no evidence of drug tachyphylaxis in those patients who continued taking stable doses of medication. With some exceptions, dose increments above 800 micrograms daily in 31 patients did not provide additional benefit in terms of GH and IGF-I reduction. Headache, excessive perspiration, fatigue, and joint pain were ameliorated in 83-95% of patients. Mean finger circumference was decreased significantly at the 12 month visit (P < 0.05). The most common adverse events reported were diarrhea, abdominal discomfort, loose stools, and nausea; these symptoms usually disappeared within 3 months of treatment. Five patients discontinued octreotide because of adverse events. Of 102 patients with normal baseline ultrasound examinations of the gallbladder, 24 patients (23.5%) developed gallstones (usually during the first year of treatment), and 21 patients developed sludge alone. Gallstone formation was not related to the dose of octreotide. Most patients with cholelithiasis were asymptomatic, and none developed cholecystitis. These observations suggest that octreotide is a valuable long term medical treatment for acromegaly.

Changes in immunoreactive (ir)-somatostatin, substance P, and calcitonin gene-related peptide concentrations of the human gastric mucosa were examined in subjects with nonulcer dyspepsia (NUD) and peptic ulcer to clarify the relationship between these peptides and dyspeptic symptoms. Fifty-six patients with NUD were divided into two subject subgroups as follows: 22 patients with upper abdominal discomfort, nausea, and/or vomiting (motility disorder group) and 34 patients complaining of upper abdominal pain [ulcer-like disorder (UD) group]. These patients were compared with either an age- and sex-matched group of asymptomatic outpatients without any organic disease (control group: n = 51), or to a group with peptic ulcer (PU group: n = 30). Ir-somatostatin concentrations of the gastric mucosa were significantly higher in UD group than in PU, motility disorder, or control group, and ir-substance P concentrations in the UD group were higher than in the PU group. No difference in ir-calcitonin gene-related peptide concentrations was observed among the four groups. These results indicate that there may be two distinct subgroups in NUD, and that NUD is not just a stage within the spectrum of peptic ulcer disease from the viewpoint of several gastrointestinal-hormone concentrations of the human gastric mucosa.
