The data from 359 transfusion reactions reported over a 3-year period have been compared with those obtained from 359 matched units given at the same time as the former but not implicated in a reaction. It was found that patients who developed reactions which were not accompanied by a change in body temperature received units with a longer storage time than patients experiencing febrile reactions. In addition it was noted that reactions which included a skin rash also tended to be associated with units stored for longer. In a further prospective assessment plasma histamine levels were measured in a group of 71 patients experiencing 'anaphylactoid', febrile and mixed transfusion reactions as well as in individuals in whom blood transfusions did not cause a reaction. The 'anaphylactoid' reaction group demonstrated a mean plasma histamine level in excess of 1 ng/ml, whereas mean concentrations below 0.50 ng/ml were recorded in the other 3 groups. Our data also suggested that in general, more and 'older' blood was given to the 'anaphylactoid' reactors. The high plasma histamine concentrations could readily contribute to the rash, wheeze and flushing recorded in these individuals. Thus, if a long shelf-life for stored blood is required, strategies which remove histamine from the unit may be worth considering.

Enalapril, an angiotensin converting enzyme (ACE) inhibitor, was given to 12 patients with renovascular hypertension: To five of them as a single drug after discontinuing other medications, and to seven patients as a substitute for one of their previous medications. The drug proved effective in controlling hypertension in all patients. Flushing and palpitations occurred in two of them, one of whom also showed a rise in creatinine and mild hyperkalemia. Two patients who had developed side effects while on captopril (renal deterioration in one, and severe rash in the other) tolerated enalapril well. Enalapril effectively reduced the blood pressure in the one patient with bilateral renal artery stenosis without causing renal failure.

Nicotinic acid (niacin) is a water-soluble vitamin widely used for the treatment of lipid disorders. In pharmacologic doses (1 g or more/day), alone or in combination with other lipid-lowering drugs, nicotinic acid lowers very low-density (VLDL) and low-density lipoprotein (LDL) levels, while concurrently increasing high-density lipoprotein (HDL) levels. It may reduce long-term mortality in patients with known coronary artery disease and may slow or reverse the progression of atherosclerosis. A major consideration against using nicotinic acid is the occurrence of frequent, bothersome, adverse reactions such as cutaneous flushing, skin rash, and gastric upset. Careful dosing titration may, however, minimize these effects. The beneficial effects, taken together with the low cost of nicotinic acid therapy and the relative freedom from serious side effects, have made nicotinic acid the agent of choice for the treatment of many patients with hyperlipidemia.

Forty-seven patients with chronic stable angina pectoris entered a thirteen-week open-label study with a transdermal therapeutic system of nitroglycerin in order to evaluate its clinical efficacy, safety, and patient acceptance. In 19 patients, a beta-blocker and in 17 patients a calcium-channel blocker were continued throughout the study period without alteration of their doses. The study consisted of a two-week run-in period and an eleven-week active drug period. Acute titration was done with nitroglycerin patches on the basis of weekly patient diaries on frequency of angina and sublingual nitroglycerin consumption. Overall, reductions in frequency of angina and in nitroglycerin consumption were statistically significant (p less than 0.05). Adverse reactions were common but tolerable. The reported side effects were headache in 32, skin rash in 18, dizziness in 10, palpitation and itching in 9 each, nausea in 7, flushing in 3, and vomiting in 1 patient. In conclusion, the present study demonstrates that individual dose titration with nitroglycerin patches for obtaining significant antianginal effect is essential. The present therapeutic system is convenient to use and well tolerated and had acceptable side effects in our study population.

BW 942C hydrochloride is an enkephalin analogue that has exhibited a wide separation between antidiarrheal dosages and dosages inducing adverse effects in animals. This has likewise been the case in humans when administered orally. In this study, the safety and tolerance of single 0.5-mg doses of intravenous BW 942C compared with placebo were assessed in humans. Four healthy male volunteers received BW 942C, and two received placebo. The effects of BW 942C on serum growth hormone (GH), luteinizing hormone (LH), prolactin (PR), and follicle-stimulating hormone (FSH) were assessed in three of these volunteers. No significant changes were apparent in vital signs, in clinical chemistry, hematologic and urine studies following BW 942C administration. BW 942C did not appear to alter mood as assessed by two psychologic mood scales. Prolactin levels tended to increase in volunteers receiving BW 942C two hours postinfusion. Luteinizing hormone concentrations decreased slightly at two and six hours. No trends in FSH or GH could be identified. Pulmonary function testing did not reveal any significant changes in oximetry, spirometry, or plethysmography in any of the subjects. A marked decrease in CO2 responsiveness in two subjects may indicate that BW 942C has mild ventilatory depressant effects. Untoward effects experienced in volunteers receiving BW 942C included heaviness in the limbs, nasal stuffiness, mouth dryness, facial flushing, skin rash, and prickling sensations. These effects bear a striking similarity to those experienced after parenteral administration of other enkephalin analogues. Intravenous administration of BW 942C up to 0.5 mg appears safe from a laboratory, physiologic, and clinical perspective with unusual untoward effects that may preclude rational use of the drug by the parenteral route.

Between 1976 and 1986, 258 incidents of suspected scombrotoxic fish poisoning were reported in Britain. Histamine analysis was carried out on 240 fish samples from these incidents, and 101 were found to contain greater than 5 mg histamine/100 g fish. The symptoms most consistently reported were rash, diarrhoea, flushing and headache. In recent years there has been a decrease in the number of confirmed scombrotoxic outbreaks and a trend towards more sporadic incidents. Of fish samples with greater than 20 mg histamine/100 g, 94% were from incidents in which scombrotoxic symptoms were characteristic, but where fish had 5-20 mg/100 g only 38% of incidents were clinically distinctive. Guidelines are presented based on the interpretation of quantitative histamine analysis of fish samples from scombrotoxic poisoning incidents.

An autopsy case of systemic mastocytosis without cutaneous involvement in a 76-year-old woman was described. The patient presented with general malaise, chest and epigastric discomfort, flushing of the face and progressive hepatosplenomegaly, and she terminated in hemorrhagic complications of DIC within 2 months. There was neither rash nor urticaria pigmentosa recognizable in the entire course. The diagnosis was made by the histologic identification of abnormal aggregates of mast cells in a bone marrow aspirate. These mast cell granules were chloroacetate esterase-positive, peroxidase-negative, and electronmicroscopically they were composed of fine granular materials containing variable numbers of lamellar structures. At autopsy, diffuse infiltration of the mast cells was found in the liver, spleen, bone marrow, lymph nodes, lungs, kidneys, stomach, and adrenal glands.

A questionnaire survey of British tanning salon clients disclosed that immediate side effects occurred more frequently in women using oral contraceptives. 20 questionnaires distributed to each of 146 UV-A lamp tanning salons nationwide in 1985 covered 24 questions on topics such as age, sex and skin type of the respondents, skin conditions such as acne and psoriasis, satisfaction with tan, and side effects including erythema (redness), itching, rash and nausea. Half of the subjects were young women aged 15-30, who had used the sunbed 10 to 100 times (median 20 times). Most sessions lasted 30 minutes. 98% reported that they tanned; 83% claimed they felt more relaxed; 28% complained of itching; 8% had rash or nausea. Among those with side effects, 41% with itching took oral contraceptives, compared to 27% who did not (p.005). 17% of pill users had nausea and 14% got a rash, compared to 10 and 7% of non-pill users, respectively (p.025). 195 or 19% of the 1013 respondents were on the pill. There are several conditions known to predispose to skin reddening, irritation or possibly carcinogenesis: fair skin; idiopathic light sensitivity; use of certain cosmetics or drugs such as antibiotics, antihypertension drugs, or antipsychotic agents.

Thirteen patients with painful Paget's disease of bone were treated as outpatients with low doses of synthetic salmon calcitonin 22.5-50 mug three times weekly. Treatment produced full remission of pain in a mean time of 5.5 weeks and a mean depression of serum alkaline phosphatase activity of 33%.The interval before symptomatic relief could not be predicted from the variables studied. The ultimate fall in serum alkaline phosphatase activity, however, could be predicted from the initial levels and from the early rate of decrease (P < 0.001). Biochemical resistance to treatment, which occurred in three cases, could be related to the dose and duration of treatment.Prolonged remissions of pain may occur which are not related to biochemical remission, to the dose of calcitonin, or to the duration of treatment. The side effects attributable to salmon calcitonin were transient nausea (in nine patients), transient flushing (in four), diarrhoea (in two), and rash (in one) though in only one patient did treatment have to be withdrawn prematurely because of these effects.

Thirty-nine patients received 600 mg/m2 OF MGBG intravenously every week for the treatment of advanced refractory ovarian cancer. Twenty-seven of these received adequate trials, and only two had partial remissions lasting 3 1/2 and 4 months each. Toxicity was substantial, with severe hematologic toxicity in 26%, diarrhea in 22% (severe in 7%), skin rash in 26% (severe in 7%), and vomiting in 70% (severe in 11%). Fatigue, facial paresthesias, and flushing during drug administration were frequent. It appears that MGBG in this dose and schedule has little activity against advanced ovarian cancer.
