Ranolazine-induced Elevation of Creatinine Kinase in the Absence of Statin Usage.

Ranolazine received Food and Drug Administration (FDA) approval in 2006 for the treatment of chronic angina. Ranolazine has previously been linked to the development of statin-induced myopathy, because it also inhibits CYP3A4, which increases serum statin levels. In the absence of concomitant statin therapy, elevated creatinine kinase (CK) and myalgias on ranolazine monotherapy has never been reported.

Characteristics of inflammatory eye disease associated with hidradenitis suppurativa.

OBJECTIVE: Hidradenitis suppurativa (HS) is an inflammatory skin condition that can cause profound morbidity. Patients can present with recurrent nodules, sinus tract formation, abscesses, and/or scarring, mainly affecting the intertriginous areas. Case reports have documented the coexistence of HS and inflammatory eye disease (IED). Herein, we aimed to assess the types of IED associated with HS and the outcomes of IED treatment in patients with HS. METHODS: All the cases with a diagnosis of HS and any IED were identified. Patients with episcleritis and sicca were excluded, and only those with chronic IED were included. An independent ophthalmologist reviewed notes to ensure accuracy of IED diagnosis. Demographics, IED patterns, comorbidities, treatments, and outcomes were retrieved from patient charts. RESULTS: Twenty patients [16 females (80%); 12 African Americans (60%)] were included in this study after the exclusion of 436 cases due to lack of data. The mean age at the diagnosis of HS and IED was 42.1 and 43.6 years, respectively. Thirteen patients had uveitis (65%), six had scleritis (30%), and one had peripheral ulcerative keratitis. Thirteen out of 20 patients (65%) had multiple autoimmune and/or inflammatory comorbidities, including inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, multiple sclerosis, and lupus. Seven patients (35%) did not have any comorbid inflammatory/autoimmune conditions. CONCLUSION: One-third of the patients with HS and IED did not have any autoimmune or inflammatory comorbidity that could explain the eye involvement. The potential association between HS and IED might be a manifestation of a common immune dysregulation phenomenon. Furthermore, the management of IED required an escalation of therapy to systemic immunosuppressive agents in 70% of patients with HS.

Correction: Fevers in Adult Lupus Patients.

Fevers in Adult Lupus Patients.

Variability in systemic lupus erythematosus (SLE) disease manifestations is well recognized. Lupus disease activity can range from mild to severe. Fever is a common manifestation of SLE and occurs in 36%-86% of patients. In the Modified Systemic Lupus Erythematosus Disease Activity Index (M-SLEDAI), fever is taken into account as disease activity scoring. Assessment of lupus patients with fever is an important diagnostic challenge, since the initial clinical presentation of a patient with lupus is very similar to the acute febrile phase of an infection. The attribution of fever to SLE holds only after other causes are excluded.
