Abstract
Introduction In the realm of organ transplantation, particularly heart transplantation, angioedema presents a significant challenge. This clinical condition ranges from minor facial edema to life-threatening swelling of vital structures. Its multifactorial etiology involves various factors and mechanisms, including C1 esterase inhibitor deficiency, food allergen hypersensitivity, and adverse drug reactions, notably involving angiotensin-converting enzyme (ACE) inhibitors and mechanistic target of rapamycin inhibitors (mTOR-Is). We present a rare case of sirolimus potentiated angioedema in a patient with long-standing ACE inhibitor therapy. Case A 52-year-old male with a history of heart transplant developed severe upper and lower lip edema. The patient had been on Lisinopril without any adverse events. However, sirolimus was recently added to his drug regimen. Sirolimus potentiated angioedema was suspected. Intervention Intravenous methylprednisolone, famotidine, and diphenhydramine were initiated, and both lisinopril and sirolimus were discontinued. The patient showed improvement and was discharged with oral antihistamines. Lessons Transplant physicians should be aware of the life-threatening interaction between ACE inhibitors and mTOR-Is like sirolimus. Consideration should be given to switching from an ACE inhibitor to an angiotensin-receptor blocker when initiating patients on mTOR-Is.

Abstract
Bradykinin-mediated angioedema is a rare, non-allergic, potentially life-threatening disease. ACE inhibitor-induced angioedema and hereditary angioedema (HAE) are the two most common presentations. Therapeutic options, pathophysiology and diagnosis continue to be investigated, with considerable progress in HAE over the last few decades. For all patients with bradykinin-mediated angioedema, there are several medications that should be avoided or administered with caution. Some of the triggering medications are well known, while others are suspected or of unknown significance. A common denominator is that there is no approved therapy for bradykinin-mediated angioedema as a drug side effect. Some medications, such as tissue plasminogen activator, have a higher incidence of angioedema with potential airway compromise than ACE inhibitors, although this fact is widely underappreciated. In this review, we aim to summarize what is currently known and recommended about concomitant medication in HAE patients and the interaction of other bradykinin-influencing drugs.

Abstract
ZusammenfassungBradykinin‐vermittelte Angioödeme sind seltene, nichtallergische und potenziell lebensbedrohliche Krankheiten. Die beiden bekanntesten Formen sind das ACE‐Hemmer‐induzierte Angioödem und das hereditäre Angioödem (HAE). Die therapeutischen Möglichkeiten, die Pathophysiologie und die Diagnostik werden weiter erforscht, wobei beim HAE in den letzten Jahrzehnten erhebliche Fortschritte erzielt wurden. Für alle Patienten mit Bradykinin‐vermittelten Angioödemen gibt es Medikamente, die vermieden oder mit Vorsicht verabreicht werden sollten. Einige dieser auslösenden Medikamente sind gut bekannt, bei anderen wird ein Zusammenhang vermutet oder ihre Bedeutung ist unbekannt. Ein gemeinsamer Nenner ist, dass es keine zugelassene Therapie für das Bradykinin‐vermittelte Angioödem als Arzneimittelnebenwirkung gibt. Bei einigen Medikamenten, wie dem gewebespezifischen Plasminogenaktivator, ist die Inzidenz von Angioödemen mit möglicher Beeinträchtigung der Atemwege höher als bei ACE‐Hemmern, wobei diese Tatsache weitgehend unterschätzt wird. In dieser Übersichtsarbeit fassen wir zusammen, was derzeit über die Begleitmedikation bei HAE‐Patienten und die Interaktion mit anderen Bradykinin‐beeinflussenden Medikamenten bekannt ist und empfohlen wird.

Abstract
INTRODUCTION Hypertension is a leading cause of cardiovascular disease and chronic kidney disease, resulting in premature death and disability. The Renin-Angiotensin-Aldosterone System (RAAS) blockers, including Angiotensin-Converting Enzyme (ACE) inhibitors or Angiotensin Receptor Blockers (ARBs), are used as first-line antihypertensive therapy to treat hypertensive patients with comorbidities, including diabetes, ischemic heart disease, heart failure, and chronic kidney disease. The use of RAS blockers is associated with the risks, such as hyperkalemia, angioedema, etc. The drugs potentiating them interact pharmacodynamically, resulting in adverse consequences. This review article focuses on the clinically important drug interactions of RAAS blockers. MATERIALS AND METHODS The electronic databases, such as Medline/PubMed Central/PubMed, Google Scholar, ScienceDirect, Cochrane Library, Directory of Open Access Journals (DOAJ), Embase, and reference lists were searched to identify relevant articles. RESULTS The risk of hyperkalemia may be enhanced potentially in patients receiving a RAS blocker and potassium-sparing diuretics, potassium supplements, trimethoprim, adrenergic betablockers, antifungal agents, calcineurin inhibitors, pentamidine, heparins or an NSAID, concomitantly. The patients taking ACE inhibitors and mTOR inhibitors, DPP4 inhibitors, alteplase, or sacubitril/valsartan concurrently may be at increased risk of developing angioedema. CONCLUSION Clinicians, pharmacists, and other healthcare practitioners should be accountable for medication safety. To avoid adverse implications, prescribers and pharmacists must be aware of the drugs that interact with RAAS blockers.

Abstract
On a pathophysiological level, angioedema can be differentiated into histamine- and bradykinin-mediated types. The prototype drug-associated, bradykinin-mediated form of angioedema is angiotensin-converting enzyme (ACE) inhibitor-induced angioedema. The hypothesized cause is a decrease in bradykinin degradation via ACE inhibition. In this scenario, other bradykinin-degrading enzymes assume major importance. When the effect of these enzymes is also diminished, e. g., due to genetic variants or external factors, compensation for the inhibition of ACE may be insufficient. An increased risk of angioedema has also been reported for other drugs, particularly when prescribed in combination with ACE inhibitors. Here, the suspected cause also relates to the degradation of bradykinin. When angioedema arises within the context of concomitant ACE inhibitor use, additive bradykinin degradation effects may be implicated.

Abstract
RATIONALE Drug-induced angioedema has been reported as an adverse effect of many different drugs. But small bowel angioedema associated with sirolimus (SRL) used was barely understood. It must be necessary to report a case suffering from small bowel angioedema with detailed discussion and literature review. PATIENT CONCERNS A 38-year-old Chinese woman presented with generalized gastric pain in the following day after renal transplantation. The patient began to crampy abdominal pain accompanied by nausea, vomiting, and diarrhea on postoperative day 6 (POD). DIAGNOSES We strongly suspected the angioedema was an adverse reaction to SRL. INTERVENTION The immunosuppressive regimen was switched from tacrolimus (TAC), SRL, and prednisone to TAC, mycophenolate and prednisone. OUTCOMES The symptoms were relieved within next 48 hours after withdrawing the SRL. One more CT scan showed complete resolution of bowel wall thickening and ascites. LESSONS This was the first report of small bowel angioedema associated with SRL. Drug-induced-angioedema is a relatively common presentation and is potentially fatal. It must be aware of potential adverse effects.

Abstract
Angiotensin‐converting enzyme inhibitor induced angioedema commonly involves the head and neck area. We report a case of angiotensin‐converting enzyme inhibitor induced intestinal angioedema in a heart transplant recipient on mTOR immunosuppression. A 36‐year‐old Caucasian woman with history of heart transplantation on sirolimus, tacrolimus and prednisone presented to the Emergency Department with abdominal pain, one day following lisinopril initiation. A computer tomography scan demonstrated diffuse bowel wall thickening consistent with pancolitis and edema. She was subsequently diagnosed with angiotensin‐converting enzyme inhibitor induced angioedema. Patients on mTOR immunosuppression are at higher risk for this potentially life‐threatening side effect. Knowledge of this interaction is critical for providers prescribing mTOR agents.

Abstract
Mammalian target of rapamycin inhibitor (mTOR-I)/proliferation signal inhibitors (PSI) including sirolimus and everolimus represent a new class of drugs increasingly used in solid-organ transplantation as alternatives to calcineurin inhibitors for patients with renal dysfunction, transplant coronary arterial vasculopathy or malignancy. The most frequently occurring mTOR-I/PSI-related adverse events are similar to those associated with other immunosuppressive therapies, but some side effects are more characteristic of proliferation signal inhibitors (e.g. lymphocele, arthralgia, oedema and hyperlipidaemia). The present paper review incidence, clinical presentation and mechanism of oedema within the clinical experience of mTOR-I/PSI in solid organ transplantation.

Abstract
Sirolimus (rapamycin) is an immunosuppressive agent commonly used in transplant recipients. Although sirolimus has less renal toxicity than calcineurin inhibitors, its use has been limited by its side effects. The most common cutaneous pathologies associated with sirolimus are inflammatory acneiform eruptions, lymphedema and aphthous ulcers. We present a novel cutaneous manifestation of sirolimus therapy that limited its use in at least one transplant recipient. Upon commencing sirolimus therapy, four solid organ transplant recipients developed tender, nonpruritic palmoplantar peeling within the first month of therapy. The peeling clinically resembled a mild form of hand-foot syndrome, yet none of the patients had been treated with chemotherapeutics. Desquamation presented on the palms and soles with dry vesicles and minor peeling extending to the dorsal aspects of the hands and feet. Histologically, the lesions were noninflammatory; the epidermis showed subtle separation between keratinocytes, suggesting either spongiosis or a defect in intercellular adhesion. One patient opted to discontinue treatment because of the tenderness associated with the palmoplantar peeling, which resulted in complete resolution within 2 weeks.

Abstract
SRL, an mTOR inhibitor that inhibits cell cycle progression, represents an important alternative to CNIs, which are still the cornerstones of pediatric solid organ tx. Because there are still limited data on SRL use among pediatric solid organ recipients, further studies are needed to verify the efficacy and safety of SRL. It has unique pharmacokinetic characteristics concerning dosing intervals and reduction of the dose in combination with other immunosuppressants. SRL also has antineoplastic, antiviral, and antiatherogenic advantages over other immunosuppressive agents. The adverse effects of SRL including thrombocytopenia, hyperlipidemia, proteinuria, impaired wound healing, mouth ulcers, edema, male hypogonadism, TMA, and interstitial pneumonitis must be considered carefully in pediatric population. This article reviews the most recent data on SRL application in the field of pediatric renal tx.

Abstract
BACKGROUND Immunosuppressants decrease circulating dipeptidyl peptidase IV (DPPIV) activity in transplant patients, and decreased DPPIV activity has been associated with angiotensin-converting enzyme (ACE) inhibitor-associated angioedema. One study has reported an increased incidence of ACE inhibitor-associated angioedema among transplant patients compared to published rates, while several case series report angioedema in patients taking specific immunosuppressant agents. OBJECTIVE To test the hypothesis that transplant patients are at increased risk of ACE inhibitor-associated angioedema. METHODS We assessed the proportion of transplant patients in 145 cases with ACE inhibitor-associated angioedema and 280 ACE inhibitor-exposed controls. We measured the relationship between case-control status, transplant status, and immunosuppressant use and circulating DPPIV activity. We also assessed the incidence of angioedema among consecutive patients who underwent renal or cardiac transplant and were treated with an ACE inhibitor. RESULTS Transplant patients were significantly overrepresented among ACE inhibitor-associated angioedema cases compared to controls (odds ratio 18.5, 95% CI 2.3-147.2, P = 0.0004). Immunosuppressant use, chronic renal failure, seasonal allergies and smoking were also associated with ACE inhibitor-associated angioedema in univariate analysis. The association of transplant status with ACE inhibitor-associated angioedema was no longer significant after inclusion of immunosuppressant therapy in a multivariate analysis. Dipeptidyl peptidase IV activity was significantly decreased in sera from cases compared to ACE inhibitor-exposed controls, as well as in individuals taking immunosuppressants. Two of 47 ACE inhibitor-treated renal transplant patients and one of 36 ACE inhibitor-treated cardiac transplant patients developed angioedema. CONCLUSION Transplant patients are at increased risk of ACE inhibitor-associated angioedema possibly because of the effects of immunosuppressants on the activity of DPPIV.

Abstract
BACKGROUND AND OBJECTIVE The clinical manifestation of angioedema ranges from minor facial edema up to life-threatening swelling of mouth and throat. Hereditary defects, drugs, and food allergies may play a role in the development of angioedema. We systematically investigated the incidence of angioedema in renal allograft recipients treated with mTOR inhibitors (mTORis). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS All patients in the authors' electronic database who had received mTORis (n = 309) between 2000 and 2008 were identified. Of these, 137 were additionally treated with angiotensin-converting enzyme inhibitors (ACEis). RESULTS Nine patients (6.6%, 3.8 per 100 treatment years) developed angioedema after a mean period of 123 days under combined therapy with mTORi and ACEi. Among the remaining 172 patients on mTORi, including 119 patients treated with angiotensin-receptor blockers, only two developed angioedema (1.2%, 0.5 per 100 treatment years, P = 0.01). In patients receiving mycophenolate and ACEi (n = 462), 10 instances of angioedema were found (2.1%, 0.8 per 100 treatment years, P = 0.004). CONCLUSIONS This systematic investigation demonstrated a noticeable incidence of 6.6% angioedema under combined therapy with mTORi and ACEi in kidney transplant recipients. Treatment with either ACEi or mTORi alone resulted in a significantly lower incidence of angioedema, suggesting that this combination should be avoided.

Abstract
New-onset post-transplantation food allergy has been described mainly after liver transplantation, and its pathogenesis was attributed to the immunomodulatory effects of tacrolimus therapy. The aim of the present study was to evaluate the association of food allergy with solid organ transplantation in our center. The medical records of children who underwent kidney transplantation and children who underwent liver or liver and kidney transplantation from 1986 to 2005 were reviewed. A total of 189 children (124 after kidney transplantation, 65 after liver or liver and kidney transplantation) received tacrolimus as part of the immunosuppressive regimen. New-onset post-transplantation food allergy was documented in four of them: two with liver transplants and two with combined kidney and liver transplants. The absence of new-onset food allergy in the children with isolated kidney transplants is compatible with other reports in the literature. This study supports the concept that the functioning liver itself, and not only tacrolimus immunosuppression, is a main contributor to food allergy in this patient population.

Abstract
Discovered in fungi in the remote Easter Island, sirolimus (rapamycin) shows potential beyond its obvious antiproliferative and immunosuppressant activity. Studies have demonstrated that sirolimus acts as a vascular endothelial growth factor inhibitor, providing prospective therapeutic benefits and possible prevention of tuberous sclerosis and Kaposi's sarcoma. Its ability to decrease keratinocyte proliferation may help patients with psoriasis. In those with tuberous sclerosis complex, it may prevent the development of hamartomas and reduce or eliminate them once grown by blocking the mammalian target of rapamycin, a critical regulatory kinase. A great advantage for this drug is in the decreased risk of malignancies, including Kaposi's sarcoma, associated with its use compared with other immunosuppressants, namely calcineurin inhibitors. This review will focus on the pharmacology and potential uses of sirolimus.
