Hyperhomocysteinemia in Adult Patients: A Treatable Metabolic Condition.

Hyperhomocysteinemia (HHcy) is recognized as an independent risk factor for various significant medical conditions, yet controversy persists around its assessment and management. The diagnosis of disorders afffecting homocysteine (Hcy) metabolism faces delays due to insufficient awareness of its clinical presentation and unique biochemical characteristics. In cases of arterial or venous thrombotic vascular events, particularly with other comorbidities, it is crucial to consider moderate to severe HHcy. A nutritional approach to HHcy management involves implementing dietary strategies and targeted supplementation, emphasizing key nutrients like vitamin B6, B12, and folate that are crucial for Hcy conversion. Adequate intake of these vitamins, along with betaine supplementation, supports Hcy remethylation. Lifestyle modifications, such as smoking cessation and regular physical activity, complement the nutritional approach to enhance Hcy metabolism. For individuals with HHcy, maintaining a plasma Hcy concentration below 50 µmol/L consistently is vital to lowering the risk of vascular events. Collaboration with healthcare professionals and dietitians is essential for developing personalized dietary plans addressing the specific needs and underlying health conditions. This integrated approach aims to optimize metabolic processes and reduce the associated health risks.

Case Report: Extensive Dermatitis Secondary to Severe Malnutrition, Zinc and Vitamin Deficiencies After Malabsorptive Bariatric Surgery.

Bariatric surgery is one of the most effective treatments currently available for obesity and its derived comorbidities. However, complications may occur, especially when malabsorptive surgeries like a biliopancreatic diversion is performed. We present the case of a female patient whose obesity was treated with this technique, and in the 9th year of follow-up developed an extensive dermatitis secondary to zinc deficiency and malnutrition, precipitated by therapeutic non-compliance. A close surveillance of early symptoms and signs of nutritional deficiencies as well as chronic supplementation of vitamins and trace elements is required; this case illustrates the relevance of periodical, lifelong visits to a medical physician with special training and experience in the management of post bariatric surgery patients in order to prevent, diagnosis and early treat related complications.

Efectiveness of long-term home parenteral nutrition with peripherally inserted central catheter: a case report / Eficacia de la nutrición parenteral domiciliaria de larga evolución con catéter de acceso periférico: a propósito de un caso

The use of home parenteral nutrition (HPN) in patients who can not obtain their nutritional requirements by the enteral route is increasing in recent years, allowing normalization lifestyle of patients. Neoplasm and mesenteric ischaemia are some of the diseases that most frequently require HPN in Spain. However, HPN is one of the cornerstones of the treatment of much less frequent illnesses as in the case of encapsulating peritoneal sclerosis. We present the case of a patient with encapsulating peritoneal sclerosis and HPN support for more than 7 years with a peripherally inserted central catheter (PICC) for over 6 years without complications and the autonomy to perform his normal business activity. Given the exceptional nature of the case we refer it to its publication.

El uso de la nutrición parenteral domiciliaria (NPD) en pacientes que no pueden alcanzar sus requerimientos nutricionales por la vía enteral está aumentando en los últimos años, permitiendo la normalización del estilo de vida de los pacientes. Entre las patologías que más frecuentemente precisan de la NPD en España destacan la neoplasia y la isquemia mesentérica. Sin embargo, la NPD constituye uno de los pilares básicos del tratamiento de enfermedades mucho menos frecuentes como es el caso de la esclerosis peritoneal encapsulante. A continuación presentamos el caso de un paciente diagnosticado de esclerosis peritoneal encapsulante con soporte NPD de más de 7 años de NPD con un catéter central de inserción periférica (PICC) para la NPD sin complicaciones y pudiendo realizar su actividad laboral habitual. Dado lo excepcional del caso lo remitimos para su publicación.

Insulin action in adipose tissue in type 1 diabetes.

BACKGROUND: Insulin action has been reported to be normal in type 1 diabetic patients. However, some studies have reported an insulin resistance state in these patients. The aim of this study was to investigate insulin resistance in a group of type 1 diabetic patients. We studied the insulin action in adipose tissue and analyzed the effects of duration of disease, body mass index (BMI), and glycosylated hemoglobin on insulin action at the receptor and postreceptor levels in adipocytes. METHODS: Nine female type 1 diabetic patients with different durations of disease and eight nondiabetic female patients of comparable age and BMI were studied. (125)I-insulin binding and U-[(14)C]-D-glucose transport was measured in a sample of subcutaneous gluteus adipose tissue obtained by open surgical biopsy from each subject. RESULTS: The duration of disease was negatively correlated with both (125)I-insulin binding capacity (r = -0.70, P < 0.05) and basal and maximum insulin-stimulated glucose transport (r = -0.87, P < 0.01, and r = -0.88, P < 0.01, respectively). Maximum specific (125)I-insulin binding to the receptors in adipocytes was higher in the group of patients with a shorter duration of disease (P < 0.01). Basal and maximum insulin-stimulated glucose transport was significantly higher in the group with less than 5 years of disease (P < 0.01). No correlation was found between BMI and insulin action. CONCLUSION: Female type 1 diabetic patients have normal insulin action. There is a high glucose uptake in the early phase of the disease, although a longer duration of disease appears to be a contributing factor to a decrease in insulin action in these patients, and involving both receptor and postreceptor mechanisms.

Dental problems in patients with diabetes mellitus (II): gingival index and periodontal disease.

UNLABELLED: Among the late complications associated to the diabetes mellitus, periodontal disease has been highlighted, and it can be more severe and refractory to treatment than in healthy subjects. OBJECTIVES: Determine the prevalence of gingivitis and periodontitis as well as the Community Periodontal Index of Need of Treatment (CPITN) in diabetic population compared with a control one. Analyze the histological characteristics in the gingiva of diabetic patients. STUDY DESIGN: The study sample was made up of 74 control subjects and 70 diabetics. We evaluated the following parameters: gingival status according to the Löe and Silness criterion, probe depth, loss of insertion, gingival recession and Community Periodontal Index of Need of Treatment. We also performed gingival biopsies in 42 diabetic patients and 29 controls for histological studies. RESULTS: We found a statistically higher gingivitis index, loss of insertion and gingival recession in diabetic patients compared to the control population, the same not occurring with the probe depth. We did not find significant differences in the CPITN according to the type of diabetes mellitus, metabolic control or disease duration. The biopsy study did not show significant changes in the gingiva of the diabetic patients compared to the control population. CONCLUSIONS: The gingivitis index was higher in the diabetic population. After examination of the treatment needs, we observed how the diabetic patients required more complex treatment.
