RESUMEN

BACKGROUND AND AIMS: To specify the prevalence of patients diagnosed with CF at age of ≥60 year-old and to analyze their characteristics. PATIENTS AND METHODS: Observational study of CF patients which were diagnosed at age ≥60 year-old. The analyzed variables were: age, sex, nationality, lung function parameters, conditions present at diagnosis, microbiological characteristics and genetic findings. RESULTS: eight patients were included. 7 patients were female (87.5%) with a mean age of 70.6 years (median 71.5 years, range 60-78 years). The most important findings were: sweat test >60 mEq/l; heterozygotes F508del; bronchiectasis in CT; methicillin-sensitive Staphylococcus aureus (50%) in sputum. The most patients presented a normal or mild obstructive lung function. CONCLUSIONS: CF must also be considered a disease diagnosed in adulthood, incorporating the sweat test within the usual techniques of differential diagnosis in patients with different diseases associated with CF, because genetic counselling is esencial.

RESUMEN

Objetivo. Precisar la prevalencia de enfermos con fibrosis quística (FQ) diagnosticados en edades superiores a los 18 años y analizar sus características clínicas, genéticas y microbiológicas. Pacientes y métodos. Estudio observacional, transversal y descriptivo de todos los pacientes diagnosticados de FQ a edad igual o superior a los 18 años. Las variables analizadas fueron: edad actual, edad al diagnóstico, sexo, nacionalidad, parámetros de función pulmonar, patologías presentes al momento del diagnóstico, características microbiológicas y hallazgos genéticos. Resultados. Se incluyeron 89 pacientes (14,8%, del total de 600 pacientes en seguimiento en las unidades participantes), 45 mujeres (50,6%) y 44 varones (49,4%), con una edad media al diagnóstico de 36,4 años. Ochenta y un pacientes (91%) eran de nacionalidad española. La prueba del sudor fue diagnóstica en 77 de los 89 estudiados (86,5%). Las mutaciones detectadas con mayor frecuencia fueron la F508del/otra y la G542X/otra y los hallazgos clínicos más frecuentes en el momento del diagnóstico fueron las bronquiectasias en 33 pacientes (37,1%) y la esterilidad en 12 (13,5%). Los microorganismos colonizadores más frecuentes fueron Staphylococcus aureus (S.aureus) sensible a meticilina (23,6%) y Pseudomonas aeruginosa (P. aeruginosa) (13,5%). La mayoría de los pacientes presentaban una alteración ventilatoria obstructiva leve y no tenía afectación pancreática. La prueba del sudor con frecuencia ofreció resultados no concluyentes. Conclusiones. La FQ es también una enfermedad de diagnóstico en la edad adulta. Los pacientes diagnosticados en edad adulta presentan una función pulmonar levemente alterada y una baja incidencia de afectación pancreática, por lo que su pronóstico tiende a ser favorable (AU)

Aim. To know the prevalence of the patients diagnosed of cystic fibrosis (CF) older than 18 years old of five specific Spanish Units and to analyze their clinical, genetic and microbiological characteristics. Patients and methods. Observational, cross-sectional, descriptive study of patients diagnosed with CF at age or older than 18 years. The variables analyzed were: current age, age at diagnosis, sex, nationality, lung function parameters, pathologies presented at diagnosis, microbiological features and genetic findings. Results. Eigthy nine patients (14.8% of the total of 600 CF patients followed at the participating units), of which 45 patients were female (50.6%) and 44 were males (49.4%), were included with a mean age at diagnosis of 36.4 years. Eigthy one patients (91%) were Spaniards. The sweat test was diagnostic in 77 (86.5%) of the patients studied. The sweat test was diagnostic in 77 of the 89 patients studied (86.5%). The most frequently detected mutations were F508del/other and G542X/other, and the most frequent clinical findings at diagnosis were the presence of bronchiectasis in 33 patients (37.1%) followed by sterility in 12 patients (13.5%). The most common colonizing organisms were meticillin-sensitive Staphylococcus aureus (S.aureus) (23.6%) and Pseudomonas aeruginosa (P. aeruginosa) (13.5%). Most patients presented a mild obstructive ventilatory defect and had no pancreatic involvement. The sweat test used to be indeterminate. Conclusions. CF is also a disease which diagnosis can be in adulthood. CF patients diagnosed in adulthood have a mild lung function and lower incidence of pancreatic involvement, so their prognosis tends to be favorable (AU)

RESUMEN

Complement fixative antibodies are determined with regard to Coxiella burnetii in phase II, in 106 serum samples taken from cattle in the Madrid region. The overall prevalence of antibodies was 66.98% and 11.32% was high titer. The result obtained are compared with the results from other studies.

RESUMEN

The presence of anti-HIV (human immunodeficiency virus) antibodies was determined in 325 subjects. The samples were taken from 138 convicts from Carabanchel and Ocaña I jail, 162 parenteral drug addicts (PDA) from a center for rehabilitation of drug addicts (CR), and from 14 family members and 11 stable couples of these PDAs. There was a global seroprevalence of 61.23%, 56.9% in Carabanchel, 68.7% in Ocaña I and 68.5% in the CR. When the results from the jailed convicts were analyzed according to risk factors, it was discovered that drug addiction was the most relevant since there was only a 29.4% of seropositivity in non PDAs with a statistically significant difference (p less than 0.01). This value was also higher than the seroprevalence found in the CR with a statistically significant difference (p less than 0.01). None of the family members of the CR were HIV-positive. Two stable couples were positive in this sexual contact group. This article makes clear the important role of drug addiction in the dispersion of HIV infection in our midst.
