ABSTRACT

Chronic kidney disease (CKD) represents a serious concern for the Mexican population since the main predisposing diseases (diabetes, hypertension, etc.) have a high prevalence in the country. The development of frequent comorbidities during CKD such as anemia, metabolic disorders, and hyperphosphatemia increases the costs, symptoms, and death risks of the patients. Hyperphosphatemia is likely the only CKD comorbidity in which pharmaceutical options are restricted to phosphate binders and where nutritional management seems to play an important role for the improvement of biochemical and clinical parameters. Nutritional interventions aiming to control serum phosphate levels need to be based on food tables, which should be specifically elaborated for the cultural context of each population. Until now, there are no available food charts compiling a high amount of Mexican foods and describing phosphorus content as well as the phosphate to protein ratio for nutritional management of hyperphosphatemia in CKD. In this work, we elaborate a highly complete food chart as a reference for Mexican clinicians and include charts of additives and drug phosphate contents to consider extra sources of inorganic phosphate intake. We aim to provide an easy guideline to contribute to the implementation of more nutritional interventions focusing on this population in the country.

ABSTRACT

Abstract Introduction: Hyperphosphatemia is a serious consequence of chronic kidney disease and has been associated with an increased risk for cardiovascular disease. Controlling serum phosphorus levels in patients on dialysis is a challenge for the clinicians and implies, in most cases, the use of phosphate binders (PB). Part of the reason for this challenge is poor adherence to treatment because of the high pill burden in this patient group. Objective: To assess the real-world effectiveness of sucroferric oxyhydroxide (SO) in controlling serum phosphorus levels and determine the associated pill burden. Methods: A multicenter, quantitative, retrospective, before-after study was conducted with patients receiving online hemodiafiltration. Patients who switched to SO as a part of routine care were included in the study. PB treatment, number of pills, serum phosphorus levels, and intravenous iron medication and dosage were collected monthly during the six months of treatment with either PB or SO. Results: A total of 42 patients were included in the study. After switching from a PB to SO, the prescribed pills/day was reduced 67% from 6 pills/day to 2 pills/day (p < 0.001) and the frequency of pill intake was lowered from 3 times/day to 2 times/day (p < 0.001). During the treatment with SO, the proportion of patients with serum phosphorus ≤ 5.5 mg/dL increased from 33.3% at baseline to 45% after six months of treatment. Conclusion: During the six-month follow-up with SO, serum phosphorus levels were controlled with one third of the pills/day compared to other PB.


Resumo Introdução: A hiperfosfatemia é uma grave consequência da doença renal crônica associada a risco aumentado de doença cardiovascular. O controle dos níveis séricos de fósforo dos pacientes em diálise é um desafio que requer, na maioria dos casos, o uso de quelantes de fosfato (QF). Parte da dificuldade se deve à baixa adesão ao tratamento oriunda do grande número de medicamentos receitados para esse grupo de pacientes. Objetivo: Avaliar a real eficácia do oxihidróxido sucroférrico (OHS) no controle dos níveis séricos de fósforo e determinar a carga de comprimidos associada. Métodos: Estudo multicêntrico, quantitativo, retrospectivo, antes e depois conduzido com pacientes em hemodiafiltração on-line. Pacientes remanejados para OHS como parte dos cuidados de rotina foram incluídos no estudo. Tratamento com QF, número de comprimidos, níveis séricos de fósforo, reposição férrica endovenosa e dosagens foram registrados mensalmente durante seis meses de tratamento com QF ou OHS. Resultados: Foram incluídos 42 pacientes no estudo. Após a mudança de QF para OHS, o número de comprimidos prescritos por dia caiu em 67%, de seis para duas unidades diárias (p < 0,001). A frequência de ingestão de comprimidos caiu de três para duas vezes ao dia (p < 0,001). Durante o tratamento com OHS, o percentual de pacientes com fósforo sérico ≤ 5,5 mg/dL aumentou de 33,3% no início para 45% após seis meses de tratamento. Conclusão: Durante os seis meses de seguimento com OHS, os níveis séricos de fósforo foram controlados com um terço dos comprimidos por dia em relação aos tratamentos com outros QF.

ABSTRACT

Abstract Introduction: In stage 5D chronic kidney disease (CKD 5D) patients, the encouragement of treatment adherence by health professionals is a significant clinical challenge. Objectives: This study evaluates the impact of a nutritional education programme on hyperphosphatemia, utilizing the transtheoretical model of behavior change (TMBC). Subjects and Methods: A prospective interventional study comprising 179 CKD 5D patients with hypophosphatemia. The 4-month educational programme took place during dialysis sessions. Demographic and laboratory data were evaluated, whilst the TMBC was utilized both pre- and post-intervention. Results: 132 patients showed a positive change and significant reduction in phosphate levels, whilst 47 patients showed a negative change and little reduction in phosphate levels. Positive changes were identified at different levels of literacy. 117/179 participants had ongoing treatment with sevelamer throughout the trial period. 61 patients with intact parathyroid hormone (iPTH) < 300pg/ml showed phosphate level reductions, whilst 118 patients with iPTH > 300 pg/ml also showed a decrease in phosphate levels. Conclusions: Nutritional education programmes can achieve excellent results when appropriately applied. An education programme may be effective across different literacy levels.

ABSTRACT

Transient hyperphosphatasemia of infancy and early childhood (THI) is characterized by transiently increased activity of serum alkaline phosphatase (S-ALP), predominantly its bone or liver isoform, in children under five years of age. There are no signs of metabolic bone disease or hepatopathy corresponding with the increased S-ALP. THI is benign disorder, rather laboratory than clinical disorder, which is usually accidentally detected in both healthy and sick children. When encountered in a child with either chronic bone, liver or kidney disease, it might concern the physician. We present a three year old boy with genetically confirmed Gitelman syndrome where THI was detected accidentally during periodic check-up. S-ALP peaked to 41.8 µkat/L, there were neither laboratory or clinical signs of liver or bone disease; the S-ALP dropped to normal value of 4 µkat/L 60 days later. Therefore, the patient fulfilled the criteria for THI. There were no further increases in S-ALP.


Resumo A hiperfosfatasemia transitória benigna da infância (HTBI) é caracterizada por elevação transitória da atividade da fosfatase alcalina sérica (S-ALP), predominantemente em sua isoforma óssea ou hepática, em crianças com menos de cinco anos de idade. Não há sinais de patologia óssea metabólica ou hepatopatia correspondentes ao aumento da S-ALP. A HTBI é um distúrbio benigno, mais laboratorial que clínico, normalmente detectado acidentalmente em crianças saudáveis e acometidas por alguma patologia. Quando encontrada em crianças com doença crônica óssea, hepática ou renal, maiores preocupações são justificadas. O presente relato descreve o caso de um menino de três anos de idade com síndrome de Gitelman geneticamente confirmada, em que a HTBI foi detectada acidentalmente durante um exame periódico. A S-ALP atingiu o pico de 41,8 µkat/L, sem sinais laboratoriais ou clínicos de doença hepática ou óssea. O valor de S-ALP caiu para o nível normal de 4 µkat/L 60 dias mais tarde. Portanto, o paciente satisfazia os critérios para HTBI. Não houve outros aumentos na S-ALP.

ABSTRACT

Tumor lysis syndrome (TLS) is an oncologic emergency triggered by the rapid release of intracellular material from lysing malignant cells. Most common in rapidly growing hematologic malignancies, TLS has been reported in virtually every cancer type. Central to its pathogenesis is the rapid accumulation of uric acid derived from the breakdown of nucleic acids, which leads to kidney failure by various mechanisms. Kidney failure then limits the clearance of potassium, phosphorus, and uric acid leading to hyperkalemia, hyperphosphatemia, and secondary hypocalcemia, which can be fatal. Prevention of TLS may be more effective than treatment, and identification of at-risk individuals in whom to target preventative efforts remains a key research area. Herein, we discuss the pathophysiology, epidemiology, and treatment of TLS with an emphasis on the kidney manifestations of the disease.

ABSTRACT

The tumor lysis syndrome (TLS) is a life-threatening complication caused by the massive release of nucleic acids, potassium and phosphate into the blood. This complication is the result of tumor cell lysis, which may occur due to treatment of drug sensitive and is characterized by rapid capacity of proliferation, that is often hematological origin. Moreover, the TLS can be observed before starting the treatment due to spontaneous tumor cell death, and frequently worsens when chemotherapy is initiated. TLS has high mortality, so that its prevention continues to be the most important therapeutic measure. In the intensive care unit (ICU), physicians should be aware of the clinical characteristics of TLS, which results in severe electrolyte metabolism disorders, especially hyperkalemia, hyperphosphatemia and hypocalcemia, and acute kidney injury which is a major cause of ICU mortality. An adequate strategy for the management of the TLS, combining hydration, urate oxidase, and an early admission to ICU can control this complication in most patients. The aim of this review is to provide diagnostic tools that allow to the ICU physician to recognize the population at high risk for developing the TLS, and outline a proper strategy for treating and preventing this serious complication.

ABSTRACT

Introducción. La difusión de la colonoscopía incrementó el uso del fosfato sódico oral (NaP). Se han notificado complicaciones como deshidratación, hipotensión, insuficiencia renal aguda e insuficiencia renal crónica con nefrocalcinosis, y hasta casos fatales de hiperfosfatemia severa. Basado en la evidencia científica actual, en el presente trabajo se presentan los riesgos y contraindicaciones de la utilización de laxantes de fosfato sódico y cómo evitarlos. Material y métodos. Se realizó un análisis bibliográfico sobre el tema en PubMed y Google Advanced Search, de publicaciones en español e inglés, en el que se incluyen ensayos clínicos, revisiones bibliográficas, cartas, editoriales, guías prácticas, meta análisis y revisiones Cochrane. Resultados. Las complicaciones por NaP se relacionan con patologías que incrementan la absorción del fosfato, con hiperparatiroidismo y con disfunción renal. También se asocian con dosis mayores a 60 g y con intervalos entre las tomas menores a 5 h, y son facilitadas por la deshidratación. Se reportaron algunos casos en los que no se respetaron estas condiciones. La insuficiencia renal por nefrocalcinosis es irreversible. Conclusión. Se debe realizar una selección adecuada de los pacientes para evitar el uso de NaP en aquellos que presenten riesgo de desarrollar hiperfosfatemia o insuficiencia renal; además, es necesario efectuar una correcta hidratación oral, no administrar más de 60 g de NaP y evitar que los intervalos entre las dosis sean menores a 5 h.


Introduction. The spread of colonoscopy has increased the use of oral sodium phosphate (OSP). Complications such as dehydration, hypotension, acute renal failure and chronic kidney disease with nephrocalcinosis and even fatal cases of severe hyperphosphatemia have been reported. The risk and contraindications of OSP use and the ways to avoid them are shown in this paper according to the scientific evidence. Material and methods. Bibliographic analysis on this subject is carried in PubMed and Google Advanced Search, publications in Spanish and English, including clinical trials, bibliographic revisions, letters, editorials, practical guidelines, meta analyses and Cochrane reviews. Results. OSP complications are related to pathologies that increase its absorption, with hyperparathyroidism and with kidney impairment. They are also associated with OSP doses >60 g and with dose intervals <5 h and are facilitated by dehydration. Some cases have been reported in patients without those conditions. Nephrocalcinosis kidney disease is irreversible. Conclusion. Adequate patient selection is mandatory to avoid OSP in patients with risk of developing hyperphosphatemia or renal impairment; proper oral hydration is also essential as is not administering more than 60 g OSP, and avoiding dose intervals <5 h.


Introdução. A difusão da colonoscopia aumentou o uso de fosfato de sódio oral (NaP). Têm sido relatadas complicações como desidratação, hipotensão, insuficiência renal aguda e insuficiência renal crônica com nefrocalcinose, e até casos fatais de hiperfosfatemia severa. Com base na evidência científica atual, são apresentados os riscos e contraindicações da utilização de laxantes de fosfato de sódio e a forma de evitá-los. Material e métodos. Foi feita uma análise bibliográfica sobre o tema (publicações em espanhol e inglês) em PubMed e Google Advanced Search que abrange ensaios clínicos, revisões bibliográficas, cartas, editoriais, guias práticos, meta-análise e revisões Cochrane. Resultados. As complicações por NaP se associam a patologias que aumentam a absorção de fosfato, a hiperparatiroidismo e a disfunção renal. Também se associam a doses maiores que 60 g e intervalos entre as tomadas menores que 5 h, e são facilitadas pela desidratação. São relatados casos em estas condições não foram respeitadas. A insuficiência renal por nefrocalcinose é irreversível. Conclusão. Deve ser feita uma seleção adequada dos pacientes para evitar o uso de NaP naqueles com risco de desenvolver hiperfosfatemia ou insuficiência renal; além disso, é necessário realizar uma correta hidratação oral, não administrar mais do que 60 g de NaP e evitar intervalos entre as doses menores que 5 h.

ABSTRACT

Fleet enemas are hypertonic solutions with an osmotic action and a high concentration of phosphate. When retained in the human body they have a great toxic potential, causing severe hydro-electrolyte disorders in children, especially in newborns. We report the case of a previously healthy 8-day-old newborn who needed neonatal intensive care treatment after the inadvertent administration of an osmotically active hypertonic phosphate enema. Taking into account that phosphate removal by peritoneal dialysis (PD) strongly depends on total dialysate turnover, we chose continuous flow PD (CFPD) as the treatment option, with a successful outcome. Clinical experience with this dialytic modality is limited to a few case reports in pediatric and adult patients. To the best of our knowledge, we report here the first description of CFPD in the setting of acute phosphate nephropathy in the neonatal period. The modality of PD described here has potential as an alternative management option as it is a highly efficient, methodologically simple, and low-cost method without any need for sophisticated equipment. Physicians and parents should be aware of the adverse effects of a hypertonic phosphate enema and should never use these medications in infants and newborns.
