The contribution of multiple mediators other than histamine explains the limited benefit of antihistamines alone in treating anaphylaxis order finasteride australia hair loss cure 32. Studies of histamine infusion into normal human volunteers suggest that vasodilatation is mediated by both H and H receptors buy finasteride 5mg amex hair loss medication over the counter,1 2 whereas bronchoconstriction and tachycardia are mediated by H1 receptors alone  purchase finasteride 1mg on line hair loss telogen effluvium. Thus purchase finasteride 5 mg with mastercard hair loss in men magazine, the physiologic consequences of chemical mediator release during anaphylaxis are (a) an increased vascular permeability; (b) an increased secretion from nasal and bronchiolar mucous glands; (c) smooth muscle contraction in the blood vessels, the bronchioles, the gastrointestinal tract, and the uterus; (d) migration–attraction of eosinophils and neutrophils; (e) bradykinin generation stimulated by kallikrein substances; and (f) induction of platelet aggregation and degranulation. These events act synergistically to increase the vascular permeability that in turn permits the access of a variety of plasma proteins (antibodies, complement, kinins, and coagulation proteins) to tissue sites, which further contributes to the observed inflammation. Urticaria, angioedema, respiratory obstruction (cough, wheezing, stridor, or breathlessness), and vascular collapse are the most important clinical features of anaphylaxis, and these signs and symptoms are due to the direct effects of mast cell and basophil-derived mediators on affected organ systems. Other clinical manifestations may include (a) a sense of fright or impending doom, (b) weakness or dizziness, (c) sweating, (d) sneezing, (e) rhinorrhea, (f) conjunctivitis, (g) generalized pruritus and swelling, (h) flushing, (i) hypoxemia, (j) choking, (k) dysphagia, (l) vomiting or diarrhea, (m) abdominal pain, (n) incontinence, (o) uterine cramps, and (p) loss of consciousness. Profound hypotension and shock may develop as a result of significant arteriolar vasodilatation, increased vascular permeability, cardiac arrhythmias, or irreversible cardiac failure, even in the absence of respiratory or other symptoms [3,10]. Furthermore, transient or sustained hypotension may result in local tissue ischemia, stroke, myocardial infarction, or death . Structures throughout the respiratory tract may be affected, but respiratory failure is generally the result of upper respiratory tract obstruction due to laryngeal edema or obstruction of small airways due to bronchoconstriction, mucosal edema, and hypersecretion of mucus [21,22]. The physical examination of a patient with anaphylactic shock may reveal one or more of the following: a rapid, weak, irregular, or unobtainable pulse, tachypnea, respiratory distress, cyanosis, hoarseness, stridor, dysphagia, diminished breath sounds, crackles, cough, wheezes, hyperinflated lungs, urticaria, angioedema, or conjunctival edema (Table 69. A given patient may manifest only a subset of these findings, sometimes only cardiovascular collapse or only stridor and breathlessness. Biochemical abnormalities in anaphylaxis include elevation of plasma histamine, serum or plasma tryptase, and depression of serum complement components [9,10]. Although these biochemical abnormalities codify our understanding of the pathophysiology of anaphylaxis, they are rarely evaluated in the acute management of clinically established anaphylaxis. Plasma histamine peaks by 15 minutes after the onset of anaphylaxis and returns to baseline by 60 minutes; measurement is generally not feasible unless anaphylaxis develops in the hospital. As discussed in the next section, serum or plasma tryptase may be helpful retrospectively when the diagnosis is uncertain [9,25]. Although there have been no systematic reviews of electrocardiographic findings, reports describe disturbances in rate, rhythm, repolarization, and ectopy [26–28], as well as myocardial infarction [29,30]. The setting is often suggestive as well: a patient who has just received an antibiotic or radiographic contrast media infusion or one who presents to the emergency room after a yellow jacket sting. Clinical criteria have been developed to help clinicians recognize the variable presentations of anaphylaxis [2,31]. A diagnosis of anaphylaxis is likely when any one of the following three criteria is present: (1) the rapid onset (minutes to several hours) of an illness with involvement of skin and/or mucosa (angioedema, flushing, pruritus, urticaria), and either respiratory compromise (dyspnea, wheeze, decreased peak flow, stridor, hypoxemia) or hypotension or end-organ dysfunction (collapse, syncope, incontinence); (2) onset of two or more of the following features after exposure to a likely allergen: skin and/or mucosa (angioedema, flushing, pruritus, urticaria), respiratory compromise (dyspnea, wheeze, decreased peak flow, stridor, hypoxemia), hypotension or end-organ dysfunction (collapse, syncope, incontinence), or persistent gastrointestinal symptoms (vomiting, crampy abdominal pain, diarrhea); or (3) onset of hypotension minutes to several hours after exposure to a known allergen for that patient . Recognition of the early signs and symptoms of anaphylaxis and prompt treatment are imperative to prevent progression to irreversible shock and death . However, samples obtained during the acute episode can be assayed subsequently for serum or plasma total tryptase. Total tryptase levels include both α- and β- tryptase; the former is increased in systemic mastocytosis and the latter can be elevated for up to 6 hours after the onset of a suspected anaphylactic reaction . However, the sensitivity of β-tryptase is suboptimal because levels can be normal after documented anaphylaxis, especially when caused by foods . There may be a role for serial measurements for documenting the course of systemic mast cell and basophil degranulation . As noted above, histamine is rarely assessed clinically because it must be obtained within the first hour after a reaction and requires special handling. Skin testing must be done in a carefully controlled setting due to the risk of provoking a severe reaction. Cutaneous assessment for the presence of antigen-specific IgE may be negative for several days after a reaction because mast cell and basophil degranulation at the time of the initial reaction may lead to a refractory period. Differential Diagnosis Clinical disorders that may be confused with anaphylaxis are sudden, acute bronchoconstriction in an asthmatic, vasovagal syncope, tension pneumothorax, mechanical airway obstruction, pulmonary edema, cardiac arrhythmias, myocardial infarction with cardiogenic shock, aspiration of a food bolus, pulmonary embolism, seizures, acute drug toxicity, septic shock, and toxic shock syndrome [10,31]. These can present with several of the concerning manifestations of anaphylaxis, including respiratory failure requiring intensive care. While the initial management is similar to that of anaphylaxis, there are several key differentiating clinical and laboratory features to aid in accurate diagnosis. These are discussed in more detail under the “Specific Agents and Precipitants” section later in this chapter. Anaphylaxis may occur within seconds following parenteral introduction of antigen and usually occurs within 30 minutes [1,9,33]. In contrast, the onset of anaphylaxis that follows oral administration of an antigen ranges from minutes to several hours . In a series of 164 fatal episodes of anaphylaxis, the median time between onset of symptoms and cardiac or respiratory arrest was 5 minutes for iatrogenic anaphylaxis, 15 minutes for stinging insect anaphylaxis, and 30 minutes for food-induced anaphylaxis . Severe manifestations, such as laryngeal edema, bronchoconstriction, and hypotension, if not fatal, may persist or recur for several days. Up to 20% of patients will experience biphasic or protracted anaphylaxis, with signs and symptoms recurring up to 24 hours or persisting beyond 24 hours after initial presentation . The prompt administration of epinephrine is critical and should be supplemented, when needed, with aggressive use of vasopressors, fluid replacement, and medications to counteract the effects of released chemical mediators . Injectable epinephrine, intravenous infusion materials and fluids, antihistamines, intubation equipment, a tracheostomy set, and individuals trained to use these materials should be available. Since symptoms of a systemic anaphylactic reaction may be followed by potentially fatal manifestations, patients must be serially examined and continuously monitored . Thus, the anticipation and the preparedness to deal with these potential reactions are very important. Emergency Measures the evaluation of individuals who are suspected of having anaphylaxis must be performed rapidly. The cause and mechanism of antigen exposure should be ascertained to assess how long the inciting antigen has been present and, when possible, to limit further absorption (e. The patient should be placed in a recumbent position with the legs elevated; pregnant patients may be placed in the left lateral decubitus position if inferior vena cava compression is a concern. A history of previous allergic reactions and former treatment may help to guide immediate therapy, obviating the need to try previously failed regimens in a life-threatening situation . Supportive Cardiopulmonary Measures Particular attention to the respiratory and cardiovascular systems is paramount and must include assessment for laryngeal edema and bronchoconstriction, as well as monitoring of oxygenation, blood pressure, and cardiac rhythm . Intubation and assisted ventilation may be necessary for cases of severe bronchoconstriction, and ventilator management strategies such as those used for treatment of acute severe asthma exacerbation may be necessary. Oral or nasal endotracheal intubation is usually feasible, but rarely edema of the tongue, larynx, or vocal cords may obstruct the upper airway and preclude oropharyngeal or nasopharyngeal intubation. To ensure a patent airway in such instances, cricothyroidotomy or tracheotomy may be necessary (see Chapters 8 and 9). Close electrocardiographic monitoring is indicated because the sequelae of anaphylaxis and its therapy are both potentially arrhythmogenic . Hypotension, acidosis, hypoxia, vasopressors, and bronchodilators are well-described predisposing factors for cardiac arrhythmias (see Chapter 189). Adequate intravenous or intraosseous access should be established as soon as possible, preferably with two 18- gauge or larger peripheral catheters or needles. Pharmacologic Therapy the mainstay of therapy is parenteral epinephrine (adrenaline), which acts on bronchial and cardiac β-receptors, causing bronchial dilatation and both chronotropic and inotropic cardiac stimulation. An equally important effect of epinephrine is stimulation of α-adrenergic receptors on blood vessels, which causes vasoconstriction. Inhaled β2- adrenergic agents, such as albuterol (salbutamol), complement the actions of epinephrine by reversing bronchoconstriction and reducing bronchial mucus secretion . Antihistamines, particularly the H -receptor blocker diphenhydramine,1 are useful for treating cutaneous manifestations of anaphylaxis, but are slower in onset than epinephrine and not helpful for hemodynamic compromise. Given their beneficial safety profile, they may be administered empirically unless there is a specific contraindication (e. In this setting, epinephrine should be given intravenously: 1 mg (1 mL of a 1:1,000 solution or 10 mL of a 1:10,000 solution) diluted in 1,000 mL of D W and infused at a rate of 1 5 µg per minute, titrating up to a maximum of 10 µg per minute, as needed with continuous electrocardiographic monitoring. Slow continuous infusion is preferred over bolus administration due to an excess risk of toxicity with bolus infusion . If intravenous access is not easily obtained, epinephrine may be given by intraosseous access at the same rate, starting at 1 µg per minute and titrating up to a maximum of 10 µg per minute. Another alternative is to administer epinephrine via endotracheal tube (10 mL of a 1:10,000 solution). If hypotension persists, continuous infusion of a pressor, such as norepinephrine, dopamine, or phenylephrine, is typically initiated (see Chapter 190). Preexisting β-adrenergic blockade with noncardioselective or cardioselective agents is another potential cause of refractory anaphylactic shock [37,38]. In the presence of β-blockade, anaphylaxis is characterized by bradycardia with or without atrioventricular nodal delay (in contrast to the usual tachycardia), profound and refractory hypotension, urticaria, and angioedema . Whether β-blockade truly increases the chance of developing anaphylaxis or just the severity is not known. Although α-adrenergic agents may increase in vitro release of mast cell mediators in the presence of β- blockade , the drug of first choice for treating anaphylaxis in the presence of β-blockade remains epinephrine . Dopamine, which has combined α, β, and dopaminergic activities, may be useful for shock refractory to epinephrine. Methylxanthines are not recommended in hypotensive patients because they may worsen hypotension and cause unpredictable cardiovascular toxicity . Their exact mechanism of action is not well defined, and they are not first-line agents in the treatment of bronchoconstriction. Given the distributive nature of shock in anaphylaxis, aggressive volume resuscitation should accompany epinephrine (and other vasoactive medications) when hypotension develops.

Their exact mechanism of action is not well defined, and they are not first-line agents in the treatment of bronchoconstriction. Given the distributive nature of shock in anaphylaxis, aggressive volume resuscitation should accompany epinephrine (and other vasoactive medications) when hypotension develops. For adults, normal saline is generally preferred, starting with a rapid infusion of 1 L intravenously, although some patients may require more. If intravenous access cannot be obtained, intraosseous administration of saline is an alternative . If the blood pressure does not improve with pressors and volume resuscitation, the central venous pressure or ultrasonography may provide guidance regarding the adequacy of fluid resuscitation. For refractory hypotension, serial ultrasonography or pulmonary artery catheterization (see Chapter 19) can help guide further fluid, inotropic, and vasopressor therapy, as outlined in Chapter 190. Histamine receptor antagonists are considered adjunctive therapies to be administered after epinephrine when needed to relieve itching and hives. Antihistamines are more effective for prevention than in treatment of full-blown anaphylaxis and should never be used as the primary therapy for anaphylactic shock. The H -receptor-blocker diphenhydramine (1 to 2 mg per1 kg up to 50 mg for an adult) can be given intravenously as a bolus . The H -receptor-blocker ranitidine (150 mg for adults) can be infused over 32 to 5 minutes or given intramuscularly . H -receptor-blocking2 antihistamines prevent the fall in diastolic blood pressure induced by experimental histamine infusion, but the evidence that H -receptor-2 blocking antihistamines are effective in the treatment of anaphylaxis is anecdotal. The H -blocker cimetidine has been reported to cause2 hypotension when given intravenously and should be avoided. Glucocorticoids are not of immediate clinical benefit and are considered adjunctive therapy to epinephrine and not a substitute. They may help to reduce bronchoconstriction and laryngeal edema and provide blood pressure support when used in high doses and for prolonged attacks (see Table 69. When parenteral glucocorticoids are administered, the initial dose is usually methyl prednisolone 1 to 2 mg per kg up to 125 mg (or the equivalent), intravenously. Subsequent dosing is based on the response to initial therapy; methylprednisolone may be continued every 6 to 12 hours for 72 hours in patients with persistent or recurrent symptoms [1,9,31]. Despite the theoretical basis for glucocorticoids preventing late recurrences of anaphylaxis, biphasic anaphylaxis has been reported to occur in 20% of anaphylactic reactions in spite of glucocorticoid therapy [24,41]. In this report, after an initial response to therapy, life- threatening symptoms recurred up to 8 hours later. Because of the possibility of a late recurrence, patients should be monitored in the intensive care setting for 8 to 12 hours after resolution of symptoms. Roughly 30% of anaphylaxis cases may have protracted symptoms for 5 to 32 hours despite vigorous therapy including glucocorticoids . For example, individuals with anaphylaxis secondary to aspirin are frequently sensitive to nonsteroidal anti- inflammatory drugs, such as ibuprofen, naproxen, ketorolac, and sulindac. Preservatives, such as metabisulfite, ethylenediamine, and methylparaben, have been associated with anaphylactic reactions. It is therefore helpful to review the inactive ingredients contained in medications temporally associated with anaphylaxis . Prevention for these settings involves specific recommendations, usually related to adequate time separation of triggers . In general, patients with a history of anaphylaxis should wear emergency alert jewelry, which details offending precipitants and potential cross-reacting agents. Finally, consultation with an allergist can clarify the offending trigger (if unknown) and guide appropriate evaluation and treatment plans. These three actions are the most relevant elements of postanaphylaxis care from the intensive care perspective. Thus, a substantial portion of the population is at risk for developing anaphylactic reactions to the drug. Seventy-five percent of the patients who die of penicillin anaphylaxis have experienced previous allergic reactions to the drug. As with other medications, the risk of a severe reaction is greater with parenteral administration than with oral administration . On the other hand, about 85% to 90% of individuals who report penicillin allergy are found to be nonallergic on subsequent evaluation . The minor determinant mixture of the above- noted substances is not commercially available, and it is accepted that Pen-G is adequate to represent the minor determinants. The negative predictive value of skin testing when both major and minor determinants of penicillin are used is excellent for immediate hypersensitivity reactions to penicillin . This testing does not evaluate other types of sensitivity, such as serum sickness reactions, morbilliform rashes, hemolytic anemia, and interstitial nephritis. In addition, it does not evaluate patients who may have specific allergy to a β-lactam side chain of a penicillin derivative, for example, cephalosporins or carbapenems . For critically ill patients, who need a β-lactam drug and who have a convincing history of severe β-lactam antibiotic allergy, the best strategy is to use an alternate, non–cross-reacting antibiotic or to proceed with a rapid desensitization protocol. These have become well established in clinical practice and vary slightly from institution to institution. The essentials, as described , are a series of infusions of gradually increasing concentrations (hence drug amount) over several hours with observation between infusions ending in infusion of desired/target dose of medication. A retrospective review of antibiotic desensitization for IgE- mediated allergy found that it was successful in 75% of patients . Patients with a remote or uncertain history of β-lactam allergy can be considered for a graded challenge: 10% of the target dose administered followed by observation for 30 minutes, and the remainder administered with observation. The benefit of this approach, if applicable, is that a successful graded challenge demonstrates tolerance to the antibiotic, namely, that allergy has been disproved.

This condition occurs when the disease involves the skin (bronze appearance) and the pancreas (diabetes). In the last two months, she also reports intermittent abdominal disten- sion and ‘squeezing’ pain, sometimes associated with vomiting. Regular medicines are peppermint oil capsules, mebeverine, citalopram 10 mg per day and a salbutamol inhaler. The clinical suspicion is that of inflammatory bowel disease, either Crohn’s disease or ulcerative colitis. The differential diagnoses in this case would include appendici- this, intra-abdominal infection or possible ovarian pathology. The patient is young and of child-bearing age (note negative pregnancy test) – any imaging should ideally keep ionizing radiation to a minimum. Abdominal x-ray indicated if any suggestion of ileus/obstruction, megacolon or perforation (where combined with an erect chest film to demonstrate free intra- peritoneal air). It is accurate in these groups for appendicitis/terminal ileal disease and also for renal/ pelvic cases of pain. Barium studies (small bowel meal/follow-through) are used for the further inves- tigation of suspected small bowel Crohn’s disease. There is inflammatory change in the perimesenteric fatty tissue around the involved segment which suggests inflammation affecting the full thick- ness of the bowel wall. Case 25: Woman with abdominal pain 119 A long irregular stricture is seen in the region of the terminal ileum (ure 25. The barium meal and follow-through shows appearances consistent with a Crohn’s stricture of the terminal ileum. Crohn’s disease is a chronic, relapsing inflammatory condition that can affect any part of the gastrointestinal tract from mouth to anus. Patients with small bowel involvement often present with abdominal pain, diarrhoea and weight loss and often there is a mass in the right iliac fossa. Eighty per cent of Crohn’s patients have small bowel involvement and the terminal ileum is the most common site. Other barium study findings in Crohn’s disease may be small bowel fold thicken- ing (caused by increase in the volume or fluid of cells in the mucosal or submu- cosal region) and hyperplasia of lymphoid tissue with or without mucosal erosions (aphthous ulcers). Aphthous ulcers may enlarge and deepen across the bowel wall causing the characteristic ‘rose-thorn’ ulceration. Late signs include deep fissures or ulcers, pseudopolyps, ‘cobblestone’ pattern caused by transverse and longitu- dinal fissures around pseudopolyps, and separation of oedematous bowel loops. Characteristic ‘skip lesions’ refer to the manner in which lesions occur in multiple sites along the bowel. Strictures are common, especially in the terminal ileum, and are a result of the inflammatory process, and fistulae are also common. Both Crohn’s and ulcerative colitis are associated with extraintestinal manifesta- tions, including: • Clubbing • Fatty liver, chronic active hepatitis, sclerosing cholangitis • Erythema nodosum, pyoderma gangrenosum • Amyloidosis, ankylosing spondylitis, seronegative arthritis • Uveitis, episcleritis, iritis. Magnetic resonance enterography with gadolinium contrast is an imaging modal- ity that is being increasingly used in Crohn’s disease, being useful for assessing the extent of both non-active disease and active disease.

She is a current smoker with a 40 pack-year history, she is a social drinker with no other significant history. Her respiratory rate is 18 per minute and there is reduced air entry in the right upper zone of the chest. Primary or secondary squamous cell carcinomas are the most common causes – remember head, neck and cervix as possible pri- mary sites. Tuberculosis, Staphylococcus aureus and Klebsiella also cause cavitation, although the patient would be systemically unwell. Hypercalcaemia may also be related to bone metastases which should be considered and excluded (radionuclide bone scan). A chest film 4 hours post-procedure should always be performed to ensure there is no latent pneumotho- rax (remember to review this, or arrange review and document your findings in the patient’s notes). In the right upper lobe, adjacent to the vertebral body, there is a large soft tissue lesion which contains an air – fluid level (arrow A). Note vertebral Case 26: Woman with cough and weight loss 125 body (arrow B), trachea (arrow C) and a left upper lobe bulla (arrow D). Adenocarcinoma is most commonly seen in non-smokers and females, is peripher- ally located in the lung, grows slowly but may metastasize early. Bronchoalveolar carcinoma is a subtype of adenocarcinoma which may present as a nodule or a focus of consolidation on a chest film. It may develop within an area of scarred lung fibrosis secondary to tuberculosis, bronchiectasis or scleroderma. Persistent consolidation 6–8 weeks after antibiotic therapy should raise the suspicion of cancer and patients require further investigation. Undifferentiated large cell carcinoma is associated with smoking, is usually large, centrally or peripherally located, grows rapidly and metastasizes early. Risk factors for lung cancer include cigarette smoking, male gender, scarred lung fibrosis and exposure to asbestos, uranium and radon gas. Radon gas is a colour- less, radioactive gas which is produced by the radioactive decay of uranium in soil and rocks. A relevant occupational and social history is therefore necessary when presenting symptoms suggest bron- chogenic carcinoma. She notes also a one-month history of intermittent bouts of central chest pain worse after food and notes a 2-week history of cough at night, which is non-productive but worsening. Examination Clinical examination revealed no haemodynamic compromise, respiratory examination revealed scattered coarse crepitations in the base of the right lung, but no evidence of respiratory distress. Investigations Blood tests showed no evidence of anaemia or infection with normal renal and liver function. There is a tight, ‘bird beak’-like stricture at the lower oesophageal sphincter (arrow A) with dilatation of the proximal oesophagus containing food debris (arrow B). Distal to the stricture barium contrast is seen in the stomach suggesting that fluid can traverse the stricture (arrow C). This diagnosis is made in the absence of other pathologies such as carcinoma of the oesophagus or fibrosis. The local obstruction with proximal dilatation is similar to Hirschsprung’s disease, and in most cases there is an aganglionic segment as in Hirschprung’s disease, but it is acquired rather than congenital and so presents later in life. A condition rather like achalasia can develop as a complication of American trypanosomiasis (Chagas’ disease). Barium swallow is useful as achalasia has certain characteristic features and also, as the investigation is dynamic, the hold-up of contrast and failure of sphincter relax- ation can be observed in real time. It may show diagnostic features, such as high resting pressure in the cardiac sphincter, incomplete relaxation on swallowing and absent peristalsis. If manometry is normal but clinical symptoms or radiologi- cal evidence suggest achalasia, a condition called pseudoachalasia may be present. Endoscopic or fluoroscopic balloon dilatation: where a balloon is inserted into the lower oesophagus via an endoscope or fluoroscopic guidance and it is inflat- ed to stretch the muscle of the oesophagus while leaving the mucosa intact. If a perfora- tion occurs, emergency surgery is needed to close the perforation and perform a myotomy. This is often performed endoscopically where injection of botu- linum toxin can be used, but only 30 per cent of patients have satisfactory relief at the end of one year. Untreated achalasia may lead to nocturnal inhalation of food material lodged in the oesophagus and aspiration pneumonia (as seen in the patient in this case). Carcinoma of oesophagus: Longstanding achalasia increases the risk of oesopha- geal carcinoma (roughly between 2 and 7 per cent of patients). The pain came on suddenly, was sharp in nature, did not radiate and was worse on movement and deep breathing. His trachea is central and chest expansion appears reduced on the left with reduced air entry on the left side of the chest and reduced vocal resonance. Investigations Full blood count, urea and electrolytes, and C-reactive protein are within normal limits. This is exerting some mass effect with compression and collapse of the left lung and there is also mediastinal shift to the right, sug- gesting the pneumothorax is under tension. In patients who are compromised and who have a pneumothorax clinically, then aspiration should be the priority. Patients should not be sent for a chest x-ray as they are in imminent danger of cardiorespiratory arrest. This is often the case in younger patients, but when deterioration occurs it can be rapid (increasing air in the pleural space impairs venous return to the heart and causes circulatory collapse).
