A 27-year-old woman was successfully treated with a highly dosed steroid therapy over several months during summer 1994 in the event of urticaria. In October 1994, when the patient was complaint free, therapy was abruptly terminated. In November 1994 jaundice, nausea and loss of appetite occurred. Biochemical results showed markedly elevated serum transaminases, negative hepatitis serology, normal immunoglobulins and inconspicious autoantibodies. Histology showed a florid hepatitis. In January 1995 the patient was hospitalized again in very low general and nutritional condition with a marked jaundice, high serum transaminases, insufficient liver synthesis function, established ANA(+), ASMA(+2) and normal immunoglobulins. This time histology painted out an active hepatitis going into liver cirrhosis. Evaluation in view of liver transplantation was carried out in this case of liver failure. At that time, tests showed a distinct gamma globulin fraction increase although the antibody pattern had remainded identical. An immunosuppressive therapy with azathioprine and steroids was decided upon under suspicion of an autoimmune hepatitis leading to a prompt positive response and therefore confirmation of the diagnosis. Complete biochemical remission was attained in April 1995 and a complete histological remission in March 1998.

There have been reports of increased prevalence of certain food allergies in patients with Type I latex allergy (LA). A detailed food allergy history was obtained from 137 patients with LA. Latex allergy was defined by positive history of IgE mediated reactions to contact with latex and positive skin prick test to latex and/or positive in vitro test (AlaSTAT and/or Pharmacia CAP). Food allergy was diagnosed by a convincing history of possible IgE mediated symptoms occurring within 60 minutes of ingestion. We identified 49 potential allergic reactions to foods in 29 (21.1%) patients. Foods responsible for these reactions include banana 9 (18.3%), avocado 8 (16.3%), shellfish 6 (12.2%), fish 4 (8.1%), kiwi 6 (12.2%), tomato 3 (6.1%), watermelon, peach, carrot 2 (4.1%) each, and apple, chestnut, cherry, coconut, apricot, strawberry, loquat, one (2.0%) each. Reactions to foods included local mouth irritation, angioedema, urticaria, asthma, nausea, vomiting, diarrhea, rhinitis, or anaphylaxis. Our study confirms the earlier reports of increased prevalence of food allergies in patients with LA. We also report increased prevalence of shellfish and fish allergy not previously reported. The nature of cross reacting epitopes or independent sensitization between latex and these foods is not clear.

Moxifloxacin (BAY 12-8039) is an investigational 8-methoxy-fluoroquinolone with broad-spectrum gram-positive and gram-negative activity. To determine the absolute bioavailability of moxifloxacin, this open-label, randomized, crossover study compared the pharmacokinetic characteristics of a single 100-mg dose administered either orally or intravenously as a 60-minute infusion in 10 healthy male volunteers (mean age [+/- SD], 29.3+/-7.1 years; mean weight [+/- SD], 77.7+/-8.7 kg). Geometric mean values for oral/IV moxifloxacin were as follows: peak serum concentration, 1.15/1.34 mg/L, and area under the concentration-time curve over 48 hours, 9.86/10.89 mg x h/L. The geometric mean absolute bioavailability of oral moxifloxacin was 91.8%. Mean renal clearance was approximately 2.3 L/h after administration of both the single oral and IV formulations, which suggests lack of active tubular secretion of moxifloxacin. Both the oral and IV formulations were well tolerated, with 5 reported possible or probable drug-related adverse events; they included headache, nausea, and localized urticaria. In summary, a single oral dose of moxifloxacin was extensively absorbed in healthy young men. Further studies are necessary in actual patients to confirm the viability of IV to oral conversion at the same dose of moxifloxacin.

A prospective study was carried out to assess the occurrence and character of adverse cutaneous reactions in patients receiving ticlopidine hydrochloride to prevent subacute thrombosis after having undergone placement of coronary stents. During a 1-year period such patients were requested to report any adverse cutaneous reactions, and those with skin reactions were referred for dermatological evaluation. Among the 136 patients who underwent stent placement by one of the authors, 20 were referred for dermatological evaluation. Of these, 16 (11.8%) fit the case definition of ticlopidine-associated cutaneous reactions. In the first 8 consecutive patients ticlopidine was withdrawn (in 2 of these a rechallenge test was later performed); in the next 8 patients ticlopidine was not discontinued before completion of the intended 4-week period of treatment. Patients remained under weekly follow-up and underwent a weekly blood count. Skin biopsies were obtained in 5 patients with different types of eruptions. The skin reactions appeared from 2 to 21 days after commencement of ticlopidine (mean, 10 days), lasting from 2 to 30 days (mean, 5 days). Only 3 patients had other adverse effects: neutropenia in 1 and abdominal pain and nausea in 2. The most common presentations were urticaria, pruritus, and maculopapular eruption. In 3 patients there were previously unreported reactions: fixed drug eruption, erythromelalgia-like eruption, and erythema multiforme-like eruption. Of note was the rapid clearing of the skin eruption in most cases even when the drug was not withdrawn. It was concluded that adverse cutaneous reactions are relatively common in association with ticlopidine treatment but that serious reactions are rare and the disappearance of the signs and symptoms is rapid, suggesting that discontinuation of the drug is not usually imperative.

A generalized allergic reaction to or anaphylaxis from honeybee sting may involve the skin with erythema, puritus, urticaria, or angioedema; the respiratory tract with laryngeal edema, and brochospasm; the cardiovascular system with myocardial depression, hypotension, and shock; and the gastrointestinal system with nausea, vomiting, and incontinence. Acute pulmonary hemorrhage following a honeybee sting has never been reported. We describe a previously healthy 14-year-old girl who developed acute pulmonary hemorrhage, hypotension, and generalized skin rash after a single honeybee sting on her right fourth finger. Her serum immunoglobulin E (IgE) was high (360 IU/mL). Chest X-ray revealed perihilar alveolar infiltrative lesions. Metabolic acidosis and hypoxemia were also found. After treatment with antihistamines, dopamine, corticosteroids, bronchodilaters, fluid replacement, and mechanical ventilation, her condition improved dramatically. A hypersensitivity reaction to honeybee venom is the most likely explanation for this unusual case of acute pulmonary hemorrhage.

Metronidazole is an antimicrobial, antiprotozoal agent that has been widely used in the treatment of a variety of infections. Some therapeutic indications necessitate prolonged treatment with metronidazole. Peripheral neuropathy is a potential metronidazole-induced toxicity, which has been reported in only a few isolated retrospective studies. This prospective study was designed to determine the toxic profile of metronidazole in patients undergoing long-term treatment with this drug. In the present study, 17 patients of both sexes, aged between 20 and 50 years, with body weights ranging from 46 to 62 kg and who were suffering from various medical ailments were recruited. The patients received 400 mg t.i.d. oral metronidazole in a total dose of 16.8-39.6 g for 2-4 weeks. It was found that patients usually suffered from some of the toxic symptoms of metallic taste, headache and dry mouth and to a lesser extent nausea, glossitis, urticaria, pruritus, urethral burning and dark colored urine. Symptoms were irrespective of sex and directly proportional to duration of therapy. Deep tendon ankle jerks were maximally reduced in four patients and sense of vibration at the level of olecranon and patella was affected in two patients. Distal latency and velocity of the sural and posterior tibial nerves were significantly affected (p < 0.01) compared with control values. These results indicate possible motor-sensory neurotoxicity involving the lower limbs due to long-term metronidazole therapy.

A forty-four-year-old Japanese female, who had persistant rhinorrhea, was administered Benza block tablets orally along with two other medicines. Immediately after ingestion, the patient displayed itching of the right upper eyelid, followed by coughing, sneezing, nasal discharge, nasal obstruction, nausea, vomiting, swelling of the face, and dyspnea. She had edema, a wheal extending from the face to the neck, and swelling of the eyelids and lips. Her symptoms subsided after treatment. Her reaction to ibuprofen, which was contained in the Benza Block tablets, was confirmed by a positive reaction to prick testing. From the results of these examinations, our patient was diagnosed as having anaphylaxis due to the ibuprofen in the Benza Block tablets. A review of the literature revealed no previous reports of anaphylaxis due to ibuprofen, although a few cases of ibuprofen urticaria have been reported.

In the last 10 years, the use of intravenous contrast media in magnetic resonance (MR) has become well-established clinical practice. Contrast media provide critical additional diagnostic information in many instances. The gadolinium chelates constitute the largest group of MR contrast media and are considered to be very safe. These agents are thought to be safer than nonionic iodinated contrast agents. Unlike x-ray agents, the gadolinium chelates are not nephrotoxic. Minor adverse reactions, including nausea (1%-2% for all agents) and hives (<1% for all agents), occur in a very low percent of cases. Health care personnel should be aware of the (extremely uncommon) potential for severe anaphylactoid reactions in association with the use of MR contrast media and be prepared should complications arise. The four gadolinium chelates currently available worldwide, gadopentetate dimeglumine, gadoteridol, gadodiamide, and gadoterate meglumine, cannot be differentiated on the basis of adverse reactions. Far fewer patients have been examined to date with the two other agents that have widespread approval, mangafodipir trisodium and ferumoxides. These latter two agents are considered to be very safe but have a higher percentage of associated adverse reactions (7%-17% with mangafodipir trisodium and 15% with ferumoxides). This review discusses the safety issues involved with administration of intravenous contrast media in MR imaging, focusing on the six agents (four gadolinium chelates, one manganese chelate, and the last a large iron particle) with widespread use world-wide.

We report a case of a patient who suffered generalized urticaria, chest tightness, wheezing, nausea, vomiting, hypotension, and loss of consciousness. Two hours earlier she had taken Eulitop Retard following lunch. She had tolerated all the implicated food after the reaction. Allergy evaluation revealed intense positive responses to intradermal tests with bezafibrate active component and Eulitop Retard (skin tests in control subjects were negative). Specific IgE tests (RAST) to Eulitop Retard were negative. An IgE mechanism is suggested to be responsible for this adverse reaction on the basis of the positive skin tets. The delayed onset (two hours) of this anaphylactic shock is unusual. Although infrequent, it may be caused by the specific pharmacokinetic characteristics of this drug, which is a slow releasing agent, mainly absorbed in the gut. The drug was taken just after lunch, and this concomitant food ingestion could also have produced a delay in gastric drainage and a retarded drug absorption. An IgE-mediated accelerated type reaction could also explain this delay. Apparently the patient reacted after the first contact to the drug, and the absence of a sensitization period is not usual in this type of immune reponse. Finally, we recommend the performance of prick and intradermal skin tests prior to any systemic challenge when allergic reactions to fibric acid derivatives are suspected.

The purpose of this study is to evaluate the effects of high doses of injected opiates as prescribed maintenance in intravenous drugs users. This was accomplished via a randomised double-blind study with crossover at an outpatient clinic in Bern, Switzerland. The subjects were 39 patients with a long history of intravenous opioid use and persistent abuse despite treatment; they were randomly allocated to two groups. Group A was started on controlled injection of graduated doses of morphine up to a satisfying individual dose and was then switched as a double blind to heroin at a randomly determined day between week three and four. Subsequently this group was given heroin for the remaining two to three weeks of the study. Group B was started on heroin and was then switched to morphine in the same manner. Equipotent solutions of 3% morphine and 2% heroin were administered. The main outcome measures were clinical observations, structural interviews and self report of subjective experiences to assess the effects of the drugs. In 16 cases, the study had to be discontinued owing to severe morphine-induced histamine reactions. Thirteen participants in Group B presented these adverse reactions on the day of the switch-over. Full data were thus only obtainable for 17 participants. Average daily doses were 491 mg for heroin and 597 mg for morphine. The findings indicate that heroin significantly produced a lower grade of itching, flushing, urticaria and pain/nausea. A negative correlation between dose and euphoria was observed for both heroin and morphine. The authors concluded that as heroin produces fewer side effects it is the preferred high-dose maintenance prescription to morphine. The perceived euphoric effects are limited in both substances.
