Study of Quality of Life in Adults with Common Variable Immunodeficiency by Using the Questionnaire SF-36

Abstract

Background: Quality of life is a multidimensional concept that includes physical, emotional and social components associated with the disease. The use of tools to assess the Quality of Life Health Related (HRQOL) has increased in recent decades. Common variable immunode ciency (CVID) is the most commonly diagnosed primary immunode ciency. Objective: To evaluate the quality of life in patients with CVID using the questionnaire SF -36. Patients and method: A descriptive cross-sectional survey included 23 patients diagnosed with CVID, belonging to the Immunode ciency Clinic Service of Allergology and Clinical Immunology in CMN Siglo XXI, IMSS. The questionnaire SF- 36 validated in Spanish was applied. Statistical analysis: descriptive statistics with simple frequencies and percentages, inferential statistics: Fisher exact test and ANOVA to compare means. Results: The study involved 23 patients, 14 women (60%) and 9 men (40%), mean age 38.6 ± 14.7 years. The highest score was obtained in 83% emotional role. Dimensions with further deterioration in both gen- ders were: 54% general health, vitality 59% and physical performance 72%. No differences were found regarding gender. The only issue in which statistically signi cant differences were found in patients with more than 3 comorbidities was change in health status in the past year (p=0.007). Patients with severe comorbidities, such as haematological-oncological (leukemias, lymphomas, neoplasms), and pulmonary (severe bronchiectasis) showed further deterioration in the aspects of physical performance 73% and 64% emotional role. 65% of patients reported an improvement in health status in 74% in the last year. Conclusions: Adult patients with CVID show deterioration in different dimensions, particularly in the areas of general health, vitality and physi- cal performance. Patients with severe comorbidities such as leukemia, lymphomas, malignancies and severe bronchiectasis show further deterioration in some aspects of quality of life, especially in physical performance and emotional role. A higher number of comorbidities was signi cantly associated with a lower score in changing health. The questionnaire SF-36 is useful for evaluating the quality of life of our patients with CVID.
