Differences in cardiovascular safety with non‐steroidal anti‐inflammatory drug therapy—A nationwide study in patients with osteoarthritis

Osteoarthritis (OA) and the non‐steroidal anti‐inflammatory drugs (NSAIDs) used to relieve OA‐associated pain have been linked independently to increased cardiovascular risk. We examined the risk of cardiovascular events associated with NSAID use in patients with OA. We employed linked nationwide administrative registers to examine NSAID use between 1996 and 2015 by Danish patients with OA aged ≥18 years. Using adjusted Cox proportional hazard analyses, we calculated the risk of the composite outcome of cardiovascular death, non‐fatal myocardial infarction and non‐fatal ischaemic stroke/TIA, and of each outcome separately, up to 5 years after OA diagnosis. Of 533 502 patients included, 64.3% received NSAIDs and 38 226 (7.2%) experienced a cardiovascular event during follow‐up. Compared with non‐use, all NSAIDs were associated with increased risk of the composite outcome: hazard ratio (HR) for rofecoxib, 1.90 (95% confidence interval, 1.74‐2.08); celecoxib, 1.47 (1.34‐1.62); diclofenac, 1.44 (1.36‐1.54); ibuprofen, 1.20 (1.15‐1.25); and naproxen, 1.20 (1.04‐1.39). Similar results were seen for each outcome separately. When celecoxib was used as reference, ibuprofen (HRs: 0.81 [CI: 0.74‐0.90]) and naproxen (HRs: 0.81 [0.68‐0.97]) exhibited a lower cardiovascular risk, even when low doses were compared. Low‐dose naproxen and ibuprofen were associated with the lowest risks of the composite outcome compared to no NSAID use: HRs: 1.12 (1.07‐1.19) and 1.16 (0.92‐1.42), respectively. In patients with OA, we found significant differences in cardiovascular risk among NSAIDs. Naproxen and ibuprofen appeared to be safer compared to celecoxib, also when we examined equivalent low doses. In terms of cardiovascular safety, naproxen and ibuprofen, at the lowest effective doses, may be the preferred first choices among patients with OA needing pain relief.     

Duodenal ulcers preceding cervical tuberculous lymphadenitis

Lymphadenitis is the most common presentation of extra pulmonary tuberculosis, whereas gastrointestinal localization, particularly duodenal involvement, is rare. We report a case of extra pulmonary tuberculosis with association between cervical lymphadenitis and duodenitis with multiple ulcers, not responsive to treatment with protonic pump inhibitors, in a human immunodeficiency virus‐seronegative adult woman of Eritrean origin. Clinical patterns of duodenal TB, diagnostic difficulties and aetiopathogenesis are discussed according to the literature. In this case report it is suggested that tuberculous infection must be considered when duodenal ulcers fail to respond to proton pump inhibitors, especially when the patient comes from an endemic area.     

Incidence of orolingual angioedema after intravenous thrombolysis for stroke

Introduction

Orolingual angioedema (OA) is a known adverse effect of intravenous (i.v.) alteplase. We analyzed all patients treated with i.v. alteplase for stroke at our hospital since approval of i.v. thrombolysis in Italy in 2004 to assess the incidence of this complication.

Patients and results

Four hundred thirty-three patients received alteplase for stroke from April 2004 to May 2017. Two women developed OA (0.4%; 95% confidence interval 0.1 to 1.6%). Angioedema was mild in one case and severe in the other, with massive swelling of the lips, tongue, and oropharyngeal mucosa, and oropharyngeal bleeding, requiring intubation. Neither patient used ACE-inhibitors.

Discussion

The incidence of orolingual angioedema was very low in our series. Although OA is usually mild, anaphylactoid reactions may rarely occur, because of the variable degree of activation of the complement system and kinin cascade caused by alteplase. In such instances, admission to neurointensive care may be required. Specific bradykinin antagonists or drugs that target the kallikrein-kinin system are beginning to be used in the more severe cases. Thus, doctors and nurses caring for acute stroke patients need to be able to recognize and treat this complication.
