Acetylsalicylic acid (ASA) and other nonsteroidal anti-inflammatory drugs (NSAID) cause a variety of symptoms in patients sensitive to these drugs. These include wheezing, rhinorrhea, flushing, pruritus, urticaria, hypotension and loss of consciousness. Conversely, improvement of asthma with the use of these drugs in patients who do not have idiosyncratic reactions to ASA (ASA-nonsensitive) has also been observed both with respect to clinical symptoms and pulmonary function tests.

Carcinoids are solid tumours arising from enterochromaffin cells, usually of the gastrointestinal or respiratory tract. They are fairly common, and in autopsy series have been present in up to 1% of cases. In contrast the carcinoid syndrome--the combination of flushing, diarrhoea, wheezing and heart disease due to release of vasoactive substances from these tumours--is rare. One estimate is that in a population of 250 000 over 10 years only two new cases would arise (Linell and Mansson, 1966).

Contrast media reactions may be classified as anaphylactoid, vasomotor, severe or life threatening, and fatal. Anaphylactoid reactions mimic immunoglobulin E-mediated hypersensitivity in that signs may consist of urticaria, angioedema, wheezing, dyspnea, hypotension, or shock. These reactions occur in 2% to 8% of all contrast media infusions. Vasomotor reactions occur in 5% to 8% of patients and consist of nausea, vomiting, flushing, and warmth. Severe reactions during which there is a concern for life occur about once per 1000 procedures. Fatalities have occurred in from 1:3000 procedures for intravenous cholangiography to between 1:10,000 to 1:100,000 procedures for intravenous urography. The pathogenesis of contrast media reactions is unknown, and various mechanisms may be associated with different clinical features. Radiocontrast media infusions can cause rises in plasma histamine and complement activation by either classic or alternate pathways or nonsequentially, yet adverse reactions may or may not occur. Abnormalities in the complement system or an increased conversion of prekallikrein to kallikrein has been demonstrated in some patients who have had anaphylactoid reactions. It is unknown if these mechanisms can explain the pathogenesis of anaphylactoid contrast media reactions. When patients who have had definite anaphylactoid reactions require a repeat procedure, the incidence of reactions ranges from 35% to 60% for intravascular infusion. Pretreatment with prednisone and diphenhydramine has been demonstrated to reduce this reaction rate to 9% in 465 procedures. Prednisone-diphenhydramine and ephedrine have further reduced the reaction rate to 3.1% in 192 procedures. These results are statistically significant (X2 = 5.4996, p = 0.019). Emergency equipment should be available should a severe reaction occur.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 291 diabetics were studied to see whether an asthmatic reaction was associated with facial flushing induced by chlorpropamide and alcohol. Of these patients, 191 reported facial flushing, of whom 12 reported breathlessness as well. Of these 12, five also described wheezing, and respiratory function tests showed them to have asthma. Three of these five patients underwent further tests, which showed that the asthmatic reaction could be prevented by giving disodium cromoglycate and the specific opiate antagonist naloxone. One patient developed wheezing when given an enkephalin analogue with opiate-like activity. Asthma induced by chlorpropamide and alcohol was concluded to be mediated by endogenous peptides with opiate-like activity such as enkephalin.

A 54-year-old woman was admitted to our hospital because of an asthmatic attack. Her first asthma attack occurred when she was 53 years old. It was followed by a flu-like infection, and was preceded for one year perennial rhinitis and loss of the sense of smell. Symptoms were perennial, and unrelated to the seasons. Because these clinical findings resembled those of aspirin-induced asthma (AIA), an aspirin-DL-lysine i.v. challenge test was done. Cough, perspiration, and flushing was provoked within 15 min after aspirin-DL-lysine injection, but FEV1 did not change. Respiratory sounds were normal and no wheezing was audible. Other cyclooxygenase inhibitors (ketoprofen, sulpyrine and acetaminophen) provoked the same symptoms. Successively increasing doses of injected aspirin-DL-lysine resulted in complete tolerance to this stimulus. We propose that aspirin-induced cough without bronchoconstriction is a new type of aspirin hypersensitivity.

Octreotide is a synthetic octapeptide somatostatin analogue which has higher potency and longer duration of action than the natural hormone. It is effective after subcutaneous administration and no rebound hypersecretion has been observed. Pharmacological effects of octreotide include inhibition of numerous hormones (growth hormone, TSH, insulin, glucagon and all gut hormones), of exocrine secretion (gastric acid, pancreatic enzyme), and of small-bowel absorption. This review deals with clinical application of octreotide in endocrine disorder. In patients with acromegaly octreotide treatment results in decrease of growth hormone (GH) and IGF-I together with tumour shrinkage and clinical improvement. Although variability in response to treatment is obvious for majority of patients the most effective dose is 100 mcg three times daily subcutaneously. Normalization of GH levels could be achieved in more than 50% of treated patients. It has also been shown that octreotide could be effective in TSH secreting pituitary adenoma, ACTH secreting adenoma as well as in non-secretory pituitary tumours. A marked biochemical and clinical responses together with longer survival have been reported in most of the patients with gastroenteropancreatic (GEP) tumours. Patients who benefit the most from octreotide therapy are those with carcionid syndrome (successful control of diarrhoea, flushing episodes and wheezing) and VIPomas (control of diarrhoea). In patients with insulin-dependent diabetes mellitus (IDDM) octreotide suppresses GH levels, postprandial blood glucose increases with resultant decrease in daily insulin requirements. In women with polycystic ovary syndrome (PCOS) octreotide has inhibitory effect on serum LH and ovarian androgens. This could have beneficial effect on ovulatory performance in women with PCOS.

The range of diseases in which intravenous immunoglobulin (IVIG) is effective has expanded significantly since its initial use in primary antibody deficiency. There are at present at least 17 preparations of IVIG in use worldwide with similar profiles of adverse effects. Infusion-related effects range in severity. Mild adverse reactions (headache, flushing, low backache, nausea, wheezing) are often associated with a fast infusion rate, and respond rapidly on slowing the infusion. Very rare episodes of life-threatening anaphylaxis may occur, particularly in those IgA-deficient patients with anti-IgA antibodies; such patients should receive an IgA-depleted preparation of IVIG. There are concerns with any blood product about safety in regard to viral transmission. The 4 outbreaks of non-A non-B hepatitis (probably hepatitis C) in the 1980s were associated with the use of particular batches of IVIG. The more recent exclusion of all anti-hepatitis C virus positive individuals from the donor pool, and the introduction of specific antiviral steps in the manufacture of IVIGs, should prevent further outbreaks. The human immunodeficiency virus (HIV) is effectively inactivated during the manufacturing process itself and HIV transmission has not been reported with IVIG. Rarely, haematological (Coombs' test positive haemolysis), neurological (aseptic meningitis) or renal (transient rises in serum creatinine) adverse effects may be seen when high doses of IVIG are used for immunomodulatory purposes. Haemolysis, due to passive transmission of blood group antibodies (anti-A, anti-D), may be prevented by selecting IVIG batches that give a negative cross-match between the recipient's red cells and IVIG.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe the clinicopathologic features of 10 patients with recurrent unexplained flushing. These patients were referred to the National Institutes of Health with a diagnosis of mastocytosis or idiopathic anaphylaxis. Both diagnoses were eliminated after evaluation. Patients reported attacks of flushing lasting 15 minutes to 2 days and associated with such symptoms as anxiety, chest tightness, paresthesia, slurred speech, weakness, and pruritus. Abdominal pain was a constant feature, often associated with cramping and an increase in stool frequency. Attacks witnessed by physicians consisted of an exaggerated blush response of the face and upper part of the chest, and were sometimes associated with tachycardia, mild hypertension, and tachypnea. Hives, angioedema, wheezing, and hypotension were not observed. Routine laboratory studies and 5-hydroxyindoleacetic acid, vanillylmandelic acid, and plasma histamine levels were normal. Plasma histamine levels did not elevate during attacks. When performed, results of bone marrow examinations, skin biopsies, and bone scans were normal. Psychiatric examinations frequently revealed somatization disorders. Patients had often been prescribed a wide variety of medications including antihistamines, nonsteroidal anti-inflammatory drugs, and steroids, with little or no benefit. Despite the benign nature of the clinical and laboratory findings, patients had undergone repeated, often invasive, examinations for several years. Whether such patients have a prominent flush response exaggerated through a somatization disorder or a relatively benign flushing disorder associated with putative mediator release remains to be determined. Recognition of this category of patients with unexplained flushing will avoid subjecting such patients to unwarranted repeated examinations, procedures, and inappropriate therapy.

The treatment of anemia in hemodialysis patients is frequently hindered by the presence of suboptimal iron stores. Intravenous iron dextran is in common use to maintain iron stores in this population, but there are little published data regarding the incidence and type of adverse events. The purpose of this study was to evaluate the safety of this medication. Charts from four hemodialysis centers of all 573 patients treated with intravenous iron dextran (INFeD; Schein Pharmaceutical, Inc, Florham Park, NJ) between July 1, 1993, and June 30, 1995, were studied. Twenty-seven patients (4.7%) had adverse reactions that were related to iron dextran. Four patients (0.7%) had reactions classified as serious (one cardiac arrest; three others required hospitalization). Ten patients (1.7%) had reactions classified as anaphylactoid. No patients died or developed permanent disability as a result of reactions. The most common adverse reactions included itching (1.5% of patients) and dyspnea or wheezing (1.5%); others included chest pain (1.0%), nausea (0.5%), hypotension (0.5%), swelling (0.5%), dyspepsia (0.5%), diarrhea (0.5%), skin flushing (0.3%), headache (0.3%), cardiac arrest (0.2%), and myalgias (0.2%). Five of all the reactions occurred during a test dose; four of these were anaphylactoid. Several factors were studied as possible predictors of adverse reactions. A positive history of drug allergy (odds ratio, 2.4; P = 0.03) and history of multiple drug allergy (odds ratio, 5.5; P = 0.0004) were significant predictors of reactions. In summary, we found serious adverse reactions to be uncommon in hemodialysis patients treated with intravenous iron dextran. Future prospective studies will help confirm this finding.

The occurrence of either medication administration errors or adverse drug reactions (ADRs) in hospitalized patients are well documented events. The combination of the two sequelae to drug therapies can lead to potentially life threatening episodes. In the case reported here, a medication administration error led to an ADR which threatened the life of a 12-month-old boy. The patient was receiving doses of cefotaxime sodium and nafcillin sodium, and was inadvertently administered a dose of cefoxitin sodium through a nursing staff medication administration errors. The patient experienced marked flushing; pitting edema, tachycardia, and a rapid respiration rate. Wheezing was absent. The patient recovered spontaneously after discontinuance of the inappropriately administered cefoxitin sodium dose, and discontinuance of cefotaxime sodium as well. Pharmacists must remain diligent in the review of the drug use process in institutions. Appropriate reconstitution, labeling, and dispensing of prescribed IV medications does not necessarily lead to appropriate administration of the drug. Pharmacy staff reviewal of the medication administration process must be carried out in conjunction with the nursing staff to ensure appropriate drug use. Patient and professional alike will benefit from such actions.
