OBJECTIVE: The aim of this study was to evaluate the association of serum magnesium levels with proton pump inhibitors (PPIs) use and other factors. METHODS: This was a cross-sectional study of 151 patients admitted with acute diseases in the Internal Medicine Division of the Hospital de Clinicas de Porto Alegre, after the exclusion of conditions that are commonly associated with hypomagnesemia: diarrhea; vomiting; chronic alcohol use; severely uncompensated diabetes mellitus; and chronic use of laxatives, diuretics or other drugs causing magnesium deficiency. RESULTS: All patients had normal serum magnesium levels. Serum albumin and creatinine levels were positively associated with serum magnesium levels, after adjusting for confounders. There was no difference between mean serum magnesium levels of PPI users and non-users, nor between men and women; there was also no correlation among age, serum phosphorus, and potassium levels with serum magnesium levels. Limitations of this study include the absence of an instrument for measuring adherence to PPI use and the sample size. CONCLUSION: The association of PPI use and hypomagnesemia is uncommon. Congenital defects in the metabolism of magnesium may be responsible for hypomagnesemia in some patients using this drug class.
OBJETIVO: O objetivo desse estudo foi verificar a associação do nível sérico do magnésio com o uso de inibidores de bomba de prótons (IBP) e outros fatores. MÉTODOS: Realizou-se estudo transversal com 151 pacientes admitidos com doenças agudas no serviço de medicina interna do Hospital de Clínicas de Porto Alegre. Foram excluídos aqueles pacientes com condições usualmente relacionadas à hipomagnesemia: diarréia; vômitos; diabéticos agudamente descompensados; uso crônico de laxantes, álcool, diuréticos ou outros fármacos relacionados. RESULTADOS: Todos os pacientes apresentaram níveis normais de magnésio. Albumina e creatinina sérica se associaram positivamente com os níveis de magnésio sérico, após ajuste para fatores confundidores. Não houve diferença no nível sérico de magnésio em usuários ou não-usuários de IBP ou entre homens e mulheres. Não houve correlação com idade, nível sérico de fósforo e potássio. As principais limitações desse estudo foram a ausência de instrumento para medir a adesão aos IBPs e o tamanho da amostra. CONCLUSÃO: A associação do uso de IBP e hipomagnesemia é rara. Defeitos congênitos no metabolismo do magnésio devem ser responsáveis pelo surgimento de hipomagnesemia em usuários de dessa classe de fármacos.

Antecedentes. El magnesio participa en numerosas reacciones enzimáticas vitales para el organismo. Objetivo. Identificar la prevalencia de hipomagnesemia (Mg < 1.6 mg/dl), sus características clínicas y su relación con el tratamiento diurético. Material y métodos. Se evaluaron 43 pacientes adultos con diagnóstico de insuficiencia cardiaca congestiva (ICC), clase funcional I-IV, sin daño renal, que recibieran el mismo tratamiento en las cuatro semanas previas al estudio. Se midieron las concentraciones de magnesio, sodio, potasio y calcio. Se registró el tratamiento diurético que estaba recibiendo cada paciente. Resultados. Tuvieron hipomagnesemia siete pacientes (16.2 por ciento) (Mg 1.5 ñ 0.07), los restantes 36 (83.8 por ciento) fueron normales (Mg 2.1 ñ 0.58). Las manifestaciones clínicas no fueron estadísticamente diferentes en ambos grupos. Las concentraciones de potasio y calcio fueron menores en el grupo de hipomagnesemia que en el de magnesio normal. Cuando se utilizó furosemida la concentración de magnesio fue menor en ambos grupos. Conclusiones. En pacientes con insuficiencia cardiaca congestiva la hipomagnesemia es un trastorno común que debería investigarse con más frecuencia por los clínicos debido al riesgo potencial de complicaciones del ritmo cardiaco

A 28-year-old woman was admitted to the ENT Department of the Faculty of Medicine, Chiang Mai University because of left otitis externa, chronic mastoiditis and facial nerve palsy (lower motor neurone). Left radical mastoidectomy with wide debridement of granulation and necrotic tissue at ear canal, dura, sigmoid sinus, ossicle and facial nerve were done two weeks after admission. Multiple pus culture from the lesion revealed different types of organisms e.g. proteus mirabilis, beta strep non group A, and enterococci beta type. Several aminoglycosides were alternately given for two months without improvement of ear infection. She developed carpopedal spasm with hypocalcemia after three weeks of such treatment. Hypomagnesemia was recognized. Calcium and milk supplement gave temporary relief, but permanent relief was obtained after aminoglycoside was discontinued. Serum electrolyte had reversed to normal on follow-up.
