Low-Fiber Intake Is Associated With High Production of Intraperitoneal Inflammation Biomarkers.

OBJECTIVE: Fiber intake influences disturbances in the gastrointestinal tract and is associated with systemic inflammation in the general population. Systemic and intraperitoneal inflammation play an important role in defining outcomes in peritoneal dialysis (PD), but the relationship between dietary fiber intake and inflammatory biomarkers has not yet been reported in the population on PD. The objective of the present study is to analyze whether or not fiber intake in patients on PD is associated with serum and intraperitoneal levels of inflammatory biomarkers. DESIGN AND METHODS: Adult and clinically stable PD patients were included in this observational and cross-sectional study. Fiber intake was assessed by means of a dietary survey and calculated using the DietPro program 5.6i. The population was divided into two groups according to the median fiber intake. We investigated interleukin (IL)-1ß, IL-6, tumor necrosis factor-α, monocyte chemoattractant protein-1 (MCP-1), B-cell-activating factor, and plasminogen-activator inhibitor-1 in both serum and peritoneal fluid. The latter was determined after a dwell time of 4 hours. RESULTS: Fifty-two patients (42% men; aged 53 ± 14 years, 36% diabetics) were evaluated. Low intake of dietary fiber was found in 90% of patients, with a median of 12.2 g per day (3.4-33.3). The group with the highest fiber intake presented lower intraperitoneal levels of IL-6, IL-8, and MCP-1. In contrast, only MCP-1 was lower in the serum of those who consumed more fiber. All the associations remained significant after adjustment for confounders with plasminogen-activator inhibitor-1 included. CONCLUSIONS: Patients on PD frequently present inadequate dietary fiber intake, which appears to have an association with the inflammatory response, particularly in the intraperitoneal component. Further prospective studies, evaluating whether or not a dietetic intervention with a focus on fiber intake affects these biomarkers and clinical outcomes, are essential to determine causality and clinical relevance.

Reversal of uremic tumoral calcinosis by optimization of clinical treatment of bone and mineral metabolism disorder.

Tumoral calcinosis is an uncommon type of extraosseous calcification characterized by large rubbery or cystic masses containing calcium-phosphate deposits. The condition prevails in the periarticular tissue with preservation of osteoarticular structures. Elevated calcium-phosphorus products and severe secondary hyperparathyroidism are present in most patients with uremic tumoral calcionosis (UTC). Case report of an obese secondary to chronic glomerulonephritis, undergoing continuous ambulatory peritoneal dialysis (CAPD) reported the appearance of painless tumors in the medial surface of fifth finger and left arm. Tumoral calcinosis was confirmed by left biceps biopsy. Poor adherence to CAPD. The patient was transferred to the "tidal" modality of peritoneal dialysis and after was treated by hemodialysis, despite the persistence of severe hyperparathyroidism progressive reduction of UTC until near to its complete disappearance. Nowadays, one year after patient received deceased-donor kidney transplantation, he presents with an improvement in secondary hyperparathyroidism. UTC should be included in the elucidation of periarticular calcification of every patient on dialysis. Relevant laboratory findings such as secondary hyperparathyroidism and elevated calcium- phosphorus products in the presence of periarticular calcification should draw attention to the diagnosis of UTC.

Resumo A calcinose tumoral é um tipo raro de calcificação extraóssea caracterizada por grandes massas císticas e elásticas contendo depósitos de fosfato de cálcio. A condição é mais prevalente no tecido periarticular e preserva estruturas osteoarticulares. A elevação do produtos cálcio-fósforo e o hiperparatireoidismo secundário grave estão presentes na maioria dos pacientes com calcinose tumoral urêmica (UTC). O relato de caso em questão refere-se a um homem de 22 anos, branco, obeso, com doença renal crônica secundária à glomerulonefrite crônica, em diálise peritoneal ambulatorial contínua (CAPD), que apresentou aparecimento de tumores indolores na face medial do quinto quirodáctilio e braço esquerdo. A calcinose tumoral foi confirmada por biópsia do bíceps esquerdo. O paciente apresentava baixa adesão à CAPD. Foi transferido para a modalidade de diálise peritoneal e depois iniciou tratamento por hemodiálise. Apesar da persistência do hiperparatireoidismo grave, houve redução progressiva da UTC, com resolução próxima do seu desaparecimento completo. Há 1 ano o paciente foi submetido a transplante renal, doador falecido, e apresentou melhora do hiperparatiroidismo secundário. A UTC deve ser incluída na elucidação de calcificação periarticular de pacientes em diálise. Os achados laboratoriais relevantes, tais como hiperparatiroidismo secundário e elevação dos produtos cálcio-fósforo na presença de calcificação periarticular, devem chamar a atenção para o diagnóstico da UTC.

Indinavir-associated toxicity mimicking urinary tuberculosis in a patient with AIDS.

This case reported to a patient with AIDS who presented persistent sterile leukocyturia and hematuria, lower back pain, bladder suffering symptoms, and renal papillary necrosis which were thought to be secondary to urinary tuberculosis but were demonstrated to be indinavir-associated side effects. The intention of this report is to remind medical professionals involved in the care of HIV+ patients of this possible association in order to avoid unnecessary investigation and to stress the need of careful periodical assessment of renal function and urinalysis in patients treated with indinavir.

Higiene: maneira simples de prevenir doenças / Hygiene: a simple manner to prevent diseases

Iniciamos nossas atividades no PEEPIN identificando, através dos prontuários, as principais doenças dos usuários da Unidade Básica de Saúde do Parque das Indústrias. Obtidos os dados, optamos por desenvolver um trabalho que visava à orientaçäo da populaçäo a respeito da necessidade de higiene pessoal. Para isso estudamos várias doenças que podem estar relacionadas à falta de higiene pessoal, como escabiose, pediculose e diarréia. Foram aplicados questionários em várias residências e nas escolas para confirmar os dados colhidos na UBS. os questionários revelaram a falta de certos hábitos de higiene entre os moradores, o que se torna ainda mais grave devido à falta de rede de esgotos na regiäo
