ABSTRACT
OBJECTIVE: To determine the prevalence of chronic renal failure (CRF) without replacement treatment (RT), and to describe the primary renal diseases and associated risk factors that might favour its evolution to terminal renal failure. Design. Cross-sectional, descriptive study. SETTING: Population attended at a primary care centre (PCC). PARTICIPANTS: Over-14s with a clinical history opened at the Bon Pastor PCC. RESULTS: Between the 1st of January 1997 and the 1st of December 1997, 12241 clinical histories were reviewed. 64 patients were identified who satisfied criteria of CRF without RT, a prevalence of 5228 patients per million inhabitants (95% CI, 3,950-6,510). 71.9% were men, and mean age was 72 (SD, 13.5). The most recent plasma creatinine averaged 2 mg/dl (SD, 0.66). Frequency according to kind of nephropathy was: 3 (4.7%) glomerular, 5 (7.8%) diabetic, 3 (4.7%) interstitial, 41 (64.1%) vascular (hypertension), 2 (3.1%) indeterminate and 10 (15.6%) unclassifiable. Associated risk factors in these patients were: 47 (73.4%) with hypertension, 16 (25%) diabetic, 26 (40.6%) with hypercholesterolaemia, 20 (31.3%) chronic consumers of analgesics, and 10 (15.6%) smokers. 51.6% of the patients suffered other cardiovascular illnesses. CONCLUSIONS: The estimated prevalence in the population of CRF without RT is 5,228 per million inhabitants. Hypertension is the risk factor most closely associated with this pathology.

Objetivo. Determinar la prevalencia de insuficiencia renal crónica (IRC) sin tratamiento sustitutivo (TSR), describir el tipo de enfermedades renales primarias y los factores de riesgo asociados que pueden favorecer su evolución hacia la insuficiencia renal terminal. Diseño. Estudio descriptivo, transversal. Emplazamiento. Población atendida por un centro de atención primaria. Participantes. Mayores de 14 años con historia clínica abierta en el CAP Bon Pastor. Resultados. Durante el período 1-I-1997 hasta 1-XII-1997 se revisaron 12.241 historias clínicas. Se identificaron 64 pacientes que cumplían criterios de IRC sin TSR; prevalencia, 5.228 pacientes por millón de habitantes (pmp) (IC del 95 por ciento, 3.950-6.510 pmp). Un 71,9 por ciento era varón, la edad media era de 72 años (DE, 13,5). La media de la última creatinina plasmática fue de 2 mg/dl (DE, 0,66). La frecuencia según tipo de nefropatía fue: glomerular, 3 (4,7 por ciento); diabética, 5 (7,8 por ciento); intersticial, 3 (4,7 por ciento); vascular (HTA), 41 (64,1 por ciento); indeterminada, 2 (3,1 por ciento), e inclasificable, 10 (15,6 por ciento). Los factores de riesgo asociados en estos pacientes fueron: hipertensos, 47 (73,4 por ciento); diabéticos, 16 (25 por ciento); hipercolesterémicos, 26 (40,6 por ciento); consumidores crónicos de analgésicos, 20 (31,3 por ciento), y 10 (15,6 por ciento), fumadores. Un 51,6 por ciento de los pacientes presentaba otras enfermedades cardiovasculares. Conclusiones. La prevalencia estimada de IRC sin TRS en la población es de 5.228 pmp, y la hipertensión es el factor de riesgo más frecuente asociado a esta patología (AU)

OBJECTIVES: Study of the prevalence of Hepatitis C infection and of cohabiting contacts. DESIGN: A descriptive crossover study. SETTING: Health District. PATIENTS: There were a total of 13,500 people with histories opened at our centre. The histories of patients attending for general medical consultations between January 1995 and December 1996 were reviewed for Ac+ to the Hepatitis C (HC) virus. RESULTS: 145 patients were found to be Ac positive for HC (1.07%; CI, 0.9-1.2). 135 were index cases and 10 contacts. The most important items of history were intravenous drug use in 33 carriers (23%), transfusion in 22 (15%), contact with non-disposable material in 97 (67%) and surgery in 119 (82%). 115 (79%) of those infected had Transaminase disorder (< x10). CONCLUSIONS: The 1.07% prevalence found was similar to other studies. Previous surgery stood out among the factors causing risk of infection. Prevalence among cohabitants was 7%, half through sexual contacts. Since there was a higher prevalence of HC+ among family members (50% sexual partners), we believe the study should be extended and followed up in the family environment.
