Iloprost is a stable prostacyclin analogue with a pharmacokinetic profile allowing nebulised administration in patients with primary pulmonary hypertension (PPH). Inhaled iloprost is a potent acute pulmonary vasodilator with a duration of action of about 60 minutes. It may exert additional long-term benefit through antiproliferative and antithrombotic effects. Inhaled iloprost 2.5 or 5 microg six or nine times daily for 12 weeks (n = 101) significantly (p < 0.01) improved a combined clinical endpoint of a > or =10% increase in distance walked in 6 minutes and an improvement of > or =1 class in New York Heart Association functional class without clinical deterioration or death (16.8 versus 4.9% of placebo recipients, n = 102) in patients with severe PPH or selected forms of nonprimary pulmonary hypertension. Statistical analysis of the response for the PPH subgroup (20.8 versus 5.5% with placebo; n = 51 and 51) was not reported. Improvements from baseline in exercise capacity and haemodynamic/gas exchange variables have been reported in patients with PPH with continued use of inhaled iloprost. In addition, improvement in preinhalation vascular resistance occurred after 12 weeks of inhaled iloprost (p < 0.01 versus placebo) in a large randomised trial. Increased cough, headache, flushing and an influenza-like syndrome were the most common adverse events in the largest trial of patients receiving inhaled iloprost. Headache, flushing and jaw pain occurred significantly more frequently with inhaled iloprost than with placebo.

The fixed-dose combination of enalapril 10mg with nitrendipine 20mg combines an ACE inhibitor with a calcium channel antagonist (CCA) and is indicated for the treatment of patients with mild-to-moderate hypertension whose blood pressure (BP) is inadequately controlled with enalapril or nitrendipine monotherapy. In randomised, double-blind clinical trials, enalapril/nitrendipine 10/20 mg/day was significantly more effective than its individual components in reducing diastolic BP (DBP) in patients with mild-to-moderate hypertension inadequately controlled with enalapril 10 mg/day or nitrendipine 20 mg/day. The fixed-dose combination was similar in efficacy at reducing DBP to amlodipine 10 mg/day in patients who failed to achieve BP control with amlodipine 5 mg/day, and to losartan/hydrochlorothiazide 50/12.5 mg/day in patients who received the combinations as first-line therapy. Enalapril/nitrendipine 10/20 mg produced a consistent antihypertensive effect that persisted for the entire 24-hour dosage interval as shown by ambulatory BP monitoring. Enalapril/nitrendipine 10/20 mg was well tolerated in clinical trials where it was administered to patients with mild-to-moderate hypertension for up to 12 weeks. The adverse events were those expected of ACE inhibitors and CCAs and included cough, headache and flushing. Evidence from clinical trials, including a pooled analysis, suggests that the incidence of oedema may be significantly lower with the fixed-dose combination than with CCA monotherapy. In conclusion, enalapril/nitrendipine 10/20 mg is a well tolerated fixed-dose combination of two established antihypertensive agents administered once daily that effectively lowers BP throughout the 24-hour dosage interval. Importantly, the fixed-dose combination may have a lower incidence of oedema than CCA monotherapy. Enalapril/nitrendipine 10/20 mg provides an additional treatment option for patients with mild-to-moderate hypertension for whom combination therapy is appropriate.

All currently available antihypertensive drugs can cause adverse drug reactions. Potential adverse drug reactions should already be taken into account when a new antihypertensive regimen is started. It is furthermore important to ask at follow-up visits specifically about common adverse reactions. The aims of this article are therefore to shortly summarise common and typical adverse drug reactions of antihypertensives. All antihypertensives may cause dizziness, hypotension, allergies, rashes, gastrointestinal complaints and dry mouth. Thiazide diuretics furthermore may cause electrolyte disturbances, dehydration and hyperuricemia, betablockers may cause bronchospasm, bradycardia, cold extremities and sleep disturbances and calcium antagonists may cause flushing, ankle oedema and gingival hyperplasia. Concerning potential lethal adverse drug reactions, it is important to know that ACE inhibitors and angiotensin receptor antagonists are contraindicated in all patients with a history of angioedema. However, angiotensin receptor antagonists are well-suited alternatives for patients with ACE inhibitor-induced cough or hypogeusia. Rare adverse drug reactions are commonly recognised only after drug approval based on spontaneous reporting. This demonstrates the importance of considering medications as potential causes of new complaints and symptoms and to reports such suspected adverse drug reactions to the national pharmacovigilance centres. Only the local or international accumulation of comparable spontaneous reports allows the drug regulation agencies to recognise new and unexpected adverse drug reactions early and to initiate appropriate measures.

A 21-year-old man, who had suddenly developed dyspnea with sneeze, cough and nasal congestion following supper, was admitted to our hospital because of hypoxemia and hypercapnia. Physical examination revealed wheezing in all lung fields and skin flushing. He took home-made Okonomi-yaki made from flour, which had been opened few months ago, and then had been remained uncooked at room temperature. Skin prick tests showed positive for problem flour and mite, but negative for just opened control flour. Collectively, we gave his diagnosis of anaphylaxis caused by mite-contaminated Okonomi-yaki.

The symptoms that result from compression of the superior vena cava are known as superior vena cava syndrome. The syndrome was originally described as secondary to infection such as tuberculosis or syphilitic aortic aneurysm. Currently, the origin is generally cancer or thrombotic events. Adenocarcinoma of the lung is the most common cause. Thrombotic causes are increasing because of the rise in use of pacemakers and central venous catheters for access or treatment purposes. Symptoms may include a feeling of fullness in the head, dyspnea, and cough. Clinical findings may include facial and neck swelling; dilated venous channels over the trunk, upper extremities, and neck; facial flushing; cyanosis; respiratory stridor and distress; and neurologic signs. Primary symptoms are in the neck and head. Treatment of superior vena cava syndrome will depend on the cause of the compression. If thrombosis is found, thrombolysis and anticoagulation may be indicated. With carcinoma or infection, specific drugs or radiation may be used. In cases of compression, dilation and stenting of the superior vena cava may be performed. In some cases a bypass of the superior vena cava may be indicated.

Hypersensitivity reactions (HSR) to oxaliplatin in patients with colorectal cancer include facial flushing, erythema, pruritus, fever, tachycardia, dyspnea, tongue swelling, rash/hives, headache, chills, weakness, vomiting, burning sensations, dizziness, and edema. We report a patient with fever as the sole manifestation of initial HSR, review the literature and discuss the management of HSR. A 57-year-old female with T3N2M0 rectal adenocarcinoma received modified FOLFOX-6. She tolerated the first 8 cycles without any toxicities except grade 1 peripheral neuropathy and nausea. During 9th and 10th infusions, she developed fever to a maximum of 38.3 centigrade with stable hemodynamic status despite medications. During 11th infusion, she developed grade 3 HSR consisting of symptomatic bronchospasm, hypotension, nausea, vomiting, cough, and fever. On examination, she was pale, cyanotic, with a temperature of 38.8 centigrade, BP dropped to 95/43 mm Hg, pulse of 116/min and O(2) saturation of 88%-91%. She was hospitalized for management and recovered in 24 h. Fever alone is not a usual symptom of oxaliplatin HSR. It may be indicative that the patient may develop serious reactions subsequently, as did our patient who developed hypotension with the third challenge. Treatment and prevention consists of slowing the infusion rate, use of steroids and antagonists of Type 1 and 2 histamine receptor antagonists, whereas desensitization could help to provide the small number of patients who experience severe HSR with the ability to further receive an effective therapy for their colorectal cancer.

The dihydropyridine calcium channel blocker lercanidipine and the ACE inhibitor enalapril are frequently used in the treatment of hypertensive patients. In April 2007, a fixed-dose combination of the two drugs was approved in Germany for the treatment of patients not responding to monotherapy. It is expected that the drug will soon be available in the other European Union markets. In this review the present literature is summarized. Two doses will be available with 10 mg lercanidipine each and 10 or 20 mg enalapril. The medication should be taken once daily, optimally =15 minutes before a meal and the consumption of grapefruit juice should be avoided. The fixed-dose combination of the two drugs has a stronger blood pressure-lowering effect than monotherapy with 20 mg enalapril or 10 mg lercanidipine. The combination is well tolerated and few patients stopped the treatment because of side effects. As expected, the most common side effects reported are cough, peripheral edema, flushing, dizziness and vertigo, occurring in 1-5% of patients. This new fixed-dose combination is a useful adjunct to the present treatment and should increase compliance and help reduce hypertension-related costs.

Two case reports discussing Korean ginseng-induced allergic reactions have been published; both were inhalation-induced respiratory allergies in occupational settings. In this report we discuss the first case of anaphylaxis that developed after an oral intake of ginseng, confirmed by an open oral challenge, a skin prick test (SPT), and a basophil activation test (BAT). A 44-year-old man experienced rhinorrhea and nasal stiffness, followed by respiratory difficulty with wheeze and abdominal pain 10 minutes after oral intake of fresh ginseng. He had suffered from episodes of allergic rhinitis during the spring season for several years. Upon presentation, a physical examination, chest radiograph, and routine laboratory tests were unremarkable. Total serum IgE level was 41 IU/mL. The SPT results showed strong positive responses to alder, birch pollens, and ginseng extracts (1:500 w/v). The methacholine bronchial challenge test revealed a positive result at PC20 of 5.83 mg/mL. The open oral challenge was performed using 50 g of fresh ginseng and showed immediate onset of facial flushing, cough, respiratory difficulty with wheeze, and abdominal pain combined with a significant decrease in FEV1 levels (54% from the baseline). Serum-specific IgE and IgG4 antibodies were not detectable by enzyme-linked immunosorbent assay. BAT showed a remarkable increase in the expression of CD203c and CD63 with the addition of ginseng extract in a dose-dependent manner, while no changes were noted in the controls. In conclusion, oral intake of Korean ginseng could induce anaphylaxis, which is mediated by non-IgE-dependent direct activation of basophil/mast cells.

Although the prognosis of maculopapular cutaneous mastocytosis (MPCM), also referred to as urticaria pigmentosa, is often benign, clinicians lack evidence to reliably predict those at risk of associated systemic manifestations. We sought to elucidate clinical markers of disease severity to provide better treatment and prognostic information for individuals with MPCM. A retrospective chart review querying characteristics of children diagnosed with MPCM in the Emory Dermatology Clinic was performed. Follow-up was obtained through a clinical encounter or telephone interview. Linear regression was used to determine predictors of the number of MPCM-related systemic symptoms. Of 67 subjects, 57% were male, and the mean age of onset was 4.5 months. The maximum number of MPCM lesions was 1 to 10 in 16%, 11 to 30 in 33%, 31 to 50 in 25%, 51 to 100 in 6%, and more than 100 in 20% of subjects. For their MPCM lesions, 46% of subjects reported itching, 34% flushing, and 25% blistering. Reported systemic symptoms included diarrhea (22%), abdominal pain (15%), wheezing or dyspnea (13%), vomiting (10%), bone pain (10%), headaches (8%), cough (10%), rhinorrhea (8%), irritability (6%), and anaphylaxis (1.5%). In a multivariate linear regression analysis, the maximum number of MPCM lesions (p = 0.02) and the number of skin symptoms (p < 0.01) were statistically significant predictors of the number of systemic symptoms, controlling for age of onset, body sites involved, and sex. The correlation between cutaneous findings and symptomatology could aid clinicians in identifying individuals with MPCM who might warrant systemic evaluation and therapy.
