Diabetics treated with sitagliptin (Januvia?, Merck & Co

Diabetics treated with sitagliptin (Januvia?, Merck & Co., Inc., Whitehouse Station, N.J.) develop “upper respiratory tract infections”, “cough”, and “sore throat” in 5% to 6% of subjects [2]. mellitus [1]. Diabetics treated with sitagliptin (Januvia?, Merck & Co., Inc., Whitehouse Station, N.J.) develop “upper respiratory tract infections”, “cough”, and “sore throat” in 5% to 6% of subjects [2]. Similar rates for these adverse events have been reported for the other DPP IV inhibitors vidagliptin [3] and saxagliptin [4]. Infections from all causes had a 34% relative risk increase (95% confidence interval 10% to 64%, P = 0.004) for sitagliptin compared to other diabetes treatments [5]. Previous studies have predicted that airway adverse events may occur with this class of drugs [6-9]. We propose that inflammatory changes may be occurring that were coded as infections in clinical studies. This is of importance in balancing the risk: benefit ratio for treatment with DPP IV inhibitors [10,11]. Two subjects who had recently started taking sitagliptin presented to our clinics with rhinorrhea, cough, dyspnea and fatigue, and requested evaluations for drug sensitivity. We challenged these index cases to determine if sitagliptin induced a reproducible syndrome. When the challenges were affirmative, we reviewed charts to identify other sitagliptin – treated subjects. We identified sitagliptin intolerant and tolerant groups, and began an analysis of potential mechanism(s) and risk factors for this new drug – induced syndrome. Methods The index cases were type II diabetic subjects who presented to an urban tertiary allergy center and a rural family practice clinic with upper and/or lower airway symptoms shortly after starting oral sitagliptin (25 and 100 mg per day, respectively). Chart reviews at the rural clinic identified 205 diabetics including 31 who had received sitagliptin as an D609 adjunct to combinations of metformin, sulfonylurea and insulin. Symptoms of fatigue, anterior and posterior rhinorrhea, cough, and sensations of wheezing or dyspnea defined a “sitagliptin intolerant population”. Fifteen intolerant and seventeen tolerant patients were identified and examined for potential risk factors and mechanisms of sitagliptin – related complaints. Outpatient evaluations included history, review of medication – related adverse events, physical examination, and, when possible, measurement of peak expiratory flow rates. Spirometry and allergy skin tests were performed at the urban clinic. Peak expiratory flow rate (PEFR) and subjective impressions of anterior D609 and posterior nasal discharge, cough, dyspnea, and fatigue symptoms scores (0 to 10 ordinal scales with 0 = none and 10 = worst in life) were assessed by the physician at the visit when sitagliptin was stopped, and by the patient for a 1 to 2 2 week follow-up period. Health insurance restrictions and referral opportunities precluded allergy testing for most of rural diabetics. Clinical diagnoses of allergic rhinitis and asthma were inferred from Allergic Rhinitis In Asthma (ARIA) [12] and Global Initiative for Asthma (GINA) [13] guidelines. Specific details are given in the Case Reports. The diagnosis of allergic rhinitis was made clinically using the symptom algorithm of the ARIA guidelines [12]. These rhinitis subjects had rhinitis with itch, sneezing, watery nasal and ocular discharge that was improved by nasal glucocorticoids, monteluklast, and/or antihistamine therapy during their target season(s). This rural patient population was unique because tree nursery farms were the chief agricultural industry in this naturally forested geographical area. The non-indigenous trees contributed a large additional burden to the high levels of diverse hardwood forest pollens. Community members paid careful attention to the timing of eye and nose itching, sneezing, congestion and cough symptoms in the setting of widespread commercial knowledge of pollination times for each cultivar. Allergic rhinitis was diagnosed frequently (19/31, 61%) in this group. A subsequent analysis of 330 consecutive practice patients found that 59% met allergic rhinitis criteria using the ARIA algorithm [12]. This compares to 42.5% in the 2005-2006 U.S. National Health and Nutrition Examination Survey where atopy was defined by having at least one positive result to 15 allergen tests [14]. Five patients (Cases 1, 3, 6, 7, 21) had positive skin tests to further support their diagnosis. Five patients wanted to restart the drug. Two wanted to know if sitagliptin was responsible for their symptoms, while three others tried because of its beneficial hypoglycaemic and weight effects. Each patient was counselled about the probable return of symptoms according to clinical standards of care. Patients measured PEFR and clinical symptoms after restarting the sitagliptin to assess drug effects.
