Osteopenia and Osteoporosis in Patients with Bronchiectasis: Association with Respiratory Parameters, Body Composition, Muscle Strength and Bone Remodeling Biomarkers.

The prevalence of osteopenia/osteoporosis has not been sufficiently studied in people with bronchiectasis not due to cystic fibrosis (BC), nor has its relationship with other variables (clinical, body composition and bone turnover and inflammation markers) been sufficiently studied. Our aim was to determine the prevalence of osteopenia and osteoporosis and related factors in patients with BC. We did a cross-sectional study in people with BC in a clinically stable state. Spirometric parameters, annual exacerbations and analysis with bone turnover markers (BTM) and inflammation markers were evaluated. Densitometry (DXA) was performed for body composition, bone mineral density (BMD) and handgrip strength. 123 patients were studied (65% women, mean age 49.6 ± 18.8, Body Mass Index (BMI) 24.8 ± 4.7 kg/m2). 62.8% and 62.5% of men and women, respectively, had normal bone mineral density, 30.2% and 22.2% osteopenia and 7% and 15% osteoporosis. 52 patients (56.2%) had low fat-free mass: 68.9% women and 28.6% men. Patients with decreased bone mass had significantly lower muscle strength, maximum expiratory volume in the first second (FEV1%), vitamin D, higher levels of C-terminal telopeptide of type 1 collagen (CTX) and total osteocalcin and underarboxylated osteocalcin (ucOC). We observed significant and negative correlations between BMD and the number of serious exacerbations per year CTX and undercarboxylated osteocalcin. We observed significant positive correlations between BMD, fat free mass index (FFMI) and handgrip dynamometry. The study suggest that the prevalence of osteoporosis was high in relation to the demographic characteristics. Respiratory parameters, body composition, muscle strength and bone remodeling markers were associated with a lower bone mineral density.

Depression and anxiety symptoms in Spanish adult patients with cystic fibrosis: associations with health-related quality of life.

BACKGROUND: Cystic fibrosis (CF) is a chronic disease with an impact on the quality of life. Self-reported symptoms of depression and anxiety were assessed in the Spanish cohort of the International Epidemiological Study on Depression and Anxiety in patients with CF (International Depression-Anxiety Epidemiological Study) and their relationship with health status and health-related quality of life (HRQoL) was evaluated. METHODS: This cross-sectional study recruited adult patients with CF at 10 Spanish centers. Patients completed the Hospital Anxiety and Depression Scale (HADS) and the Revised Cystic Fibrosis Questionnaire. Demographic and health data were recorded from medical charts. Logistic regression was used to determine the predictors of elevated symptoms of depression and anxiety (HADS≥8). RESULTS: Of the 336 participants recruited (mean age, 28.1years; 48.2% women), 41 (12.2%) had elevated depression-related scores, and 100 (29.7%) had elevated anxiety-related scores (HADS≥8). After adjusting for confounders, only less education, intravenous antibiotics, psychiatric medications and psychotherapy were significantly associated with elevated psychological symptoms. Specifically, regardless of lung function, patients who were depressed or anxious reported worse HRQoL. CONCLUSIONS: The prevalence of elevated symptoms of depression and anxiety was high in Spanish adult patients with CF, and these symptoms were associated with a decreased HRQoL.

[Home parenteral nutrition in Spain 2011 and 2012; a report of the home and ambulatory artificial nutrition group NADYA]. / Nutrición Parenteral Domiciliaria en España 2011 y 2012: informe del grupo de nutrición artificial domiciliaria y ambulatoria NADYA.

OBJECTIVE: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the years 2011 and 2012. METHODOLOGY: We compiled the data from the on-line registry introduced by reviewers of NADYA group responsible for monitoring of NPD introduced by since January 1, 2011 to december 31, 2012. Included fields were: age, sex, diagnosis and reason for HPN, access path, complications, beginning and end dates, complementary oral or enteral nutrition, activity level, autonomy degree, product and fungible material supply, withdrawal reason and intestinal transplant indication. RESULTS: Year 2010: 184 patients from 29 hospitals , representing a rate of 3.98 patients/million inhabitants/ year 2011, with 186 episodes were recorded NPD . During 2012, 203 patients from 29 hospitals , representing a rate of 4.39 patients/million inhabitants/year 2012 , a total of 211 episodes were recorded NPD . CONCLUSIONS: We observe an increase in registered patients with respect to previous years.Neoplasia remains as the main pathology since 2003. Although NADYA is consolidated registry and has been indispensable source of information relevant to the understanding of the progress of Home Artificial Nutrition in our country, there is ample room for improvement. Especially that refers to the registration of pediatric patients and the registration of complications.

Objetivo: Comunicar los datos del registro de Nutrición Parenteral Domiciliaria (NPD) del grupo de trabajo NADYA-SENPE de los años 2011 y 2012. Material y métodos: Recopilación de los datos del registro "on-line" introducidos por los colaboradores del grupo NADYA responsables del seguimiento de la NPD desde el 1 de enero de 2011 al 31 de diciembre de 2012 dividido por años naturales. Resultados: Año 2010: Se registraron 184 pacientes, procedentes de 29 hospitales, lo que representa una tasa de 3,98 pacientes/millón habitantes/año 2011, con 186 episodios de NPD. Durante el año 2012 se registraron 203 pacientes, procedentes de 29 hospitales, lo que representa una tasa de 4,39 pacientes/millón habitantes/año 2012, con un total de 211 episodios de NPD. Conclusiones: Se observa un aumento progresivo de los pacientes registrados respecto a años anteriores. El principal grupo patológico sigue siendo oncológico ocupando el primer lugar desde 2003. Aunque el registro NADYA es un registro consolidado y ha sido y es fuente imprescindible de información relevante para el conocimiento de los avances de la Nutrición Artificial Domiciliaria en nuestro país, queda un amplio margen para la mejora. En especial lo que hace referencia al registro de pacientes pediátricos y al registro de las complicaciones.

[Chonic diarrhea and malabsorption due to common variable immunodeficiency, gastrectomy and giardiasis infection: a difficult nutritional management]. / Diarrea crónica refractaria y malabsorción secundaria a hipogammaglobulinemia común variable, infestación crónica por giardia lamblia y gastrectomía total por adenocarcinoma gástrico: un manejo nutricional complejo.

Gastric cancer is a frequent cause of cancer-related mortality in the world. Surgery is the only potentially curative therapy, although the adverse effects of surgery are common and considerable. Common variable immunodeficiency is in many cases cause of gastrointestinal system problems such as chronic diarrhea caused by infestation with giardia lamblia, nodular lymphoid hiperplasia ad loss of villi leading frequently to malapsortion and malnutrition. Nutritional deficiencies due to malapsorption (postgastrectomy and secondary to loss of villi, giardiasis and common variable inmunodeficiency) are common. We present the case of a patient with gastric cancer who underwent a gastrectomy with common variable hipogammaglobulinemia and chronic infestation by giardia lamblia, with serious diarrhea resistant to treatment and malabsorption.

[D-Lactic acidosis secondary to short bowel syndrome]. / Ácidosis D-láctica secundaria a síndrome de intestino corto.

The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagnosis was D-lactic acidosis. D-lactic acidosis is a rare complication, but important for their symptoms, of this syndrome. It is due to a change in intestinal flora secondary to an overgrowth of lactic acid bacteria that produce D-lactate. D-lactic acidosis should be looked for in cases of metabolic acidosis in which the identity of acidosis is not apparent, neurological manifestations without focality and the patient has short bowel syndrome or patients who have had jejunoileal bypass surgery. Appropriate treatment usually results in resolution of neurologic symptoms and prevents or reduces further recurrences.

[Pheochromocytoma and cardiac insufficiency]. / Feocromocitoma e insuficiencia cardíaca.

Catecholamine-induced cardiomyopathy is a rare complication of pheochromocytoma. We present a case of pheochromocytoma that developed preoperative heart failure. Left ventricular dilation and severe hypokinesia were demonstrated by echocardiography. Heart failure was successfully treated with digitalis, diuretics and captopril. There were no surgical complications and the follow up showed and improvement on the systolic function evaluated by echocardiography and isotope ventriculography, 3 and 6 months after surgery. We review the pathophysiology and evolution of catecholamine induced cardiomyopathy. Preload reserve can be one of the adaptive mechanisms of the ventricle in catecholamine-induced cardiomyopathy. Conventional therapy of hypertension and heart failure can be effective to correct the symptoms of cardiac dysfunction.

Altered bioavailability due to changes in the formulation of a commercial preparation of levothyroxine in patients with differentiated thyroid carcinoma.

OBJECTIVES: In July 1995 we began noticing an unusually high rate of elevated TSH levels in patients with differentiated thyroid cancer treated with levothyroxine-specifically the brand Levothroid-becoming more obvious from September 1995. Faced with the possibility that these findings had some relationship to the drug taken, we carried out a prospective study, changing this brand of levothyroxine for another. DESIGN AND PATIENTS: We studied 58 patients with differentiated thyroid carcinoma (50 women and eight men; aged 22-75 years) who were being treated with levothyroxine and who had previously had adequate TSH suppression. Their Levothroid tablets were changed to the same dose of Dexnon tablets, and their clinical and analytical response was evaluated 2 months later. The patients were divided into two groups according to their TSH level at the start of the study: group 1, 42 patients with TSH > 0.2 mU/l (not suppressed) and group 2, 16 patients with TSH < or = 0.2 mU/l (suppressed). RESULTS: After 2 months with Dexnon the TSH levels in group 1 fell significantly (P < 0.0001) also decreasing in group (P < 0.09). The free T4 and free T3 rose significantly in both groups. After the change to Dexnon, 17 patients (40%) in group 1 had suppressed TSH and 26 (62%) had free T4 levels above the upper limit of normal vs none at baseline (P < 0.001). The group 2 patients maintained their inhibited TSH values after treatment with Dexnon, and the free T4 was above the upper limit of normal in 15 (94%) vs 3 (19%) at baseline (P < 0.001). The Levothroid tablets collected from the patients in both groups formed part of those which the manufacturer later withdraw from the market. These batches possessed the correct dosage, but they had been made from 'non-micronized' raw materials from another supplier. CONCLUSIONS: The most probable cause of the inadequate TSH suppression in our patients was the reduction in bioavailability in certain batches of Levothroid, although we are unable to rule out the possibility that the results obtained after the changeover to Dexnon were due to its greater bioavailability. Simple changes in the manufacture of levothyroxine tablets may produce important variations in their bioavailability, having an adverse effect on the clinical control of the patients, and causing extra expense by the need for repeated patient visits and thyroid function tests.
