Introduction: Up to 25% of patients with common variable immunodeficiency (CVID) debut with autoimmunity, which is related to the Freiburg classification, which is based on flow cytometry.
Objective: to determine the frequency and type of autoimmune diseases and their association with the Freiburg classification in adults with CVID.
Methods: A cross-sectional, analytical and observational study was carried out with 33 patients belonging to the Primary Immunodeficiency Clinic of a third level hospital, with a diagnosis of CVID.

Background: The consequences of SARS-CoV-2 infection in patients with primary (now called "inborn errors of immunity") or secondary immunodeficiencies is still a matter of debate. There are few reports in the literature of patients with Good's syndrome and SARS-CoV-2 infection with variable outcomes.
Clinical Case: A 51-year-old male with diagnosis of Good's syndrome treated with intravenous human immunoglobulin (IVIG) at a replacement dose with application every 21 days and prophylaxis for P.
Background: Asthma has a global prevalence of 18%. In work-related asthma, there is an association between asthma and the exposure to dust, vapors, or fumes only at the workplace, in patients with or without a previous asthma diagnosis; it represents approximately 5-25% of the cases of adult onset asthma. In Mexico, the information about this topic is scarce.

Patients with HID have infections caused by capped extracellular bacteria, mainly in the respiratory and/or gastrointestinal tract, and a higher predisposition to suffer from autoimmune diseases and cancer. Some of them are caused by well-defined genetic defects, while the cause of others is unknown.

Objective: To compare the activity rate of urticaria using the UAS7 (Urticaria Activity Score 7) in patients with and without hypothyroidism.
Background: Chronic spontaneous urticaria (CSU) is linked to thyroid disease in up to 54%, with predominance of hypothyroidism.
Objective: To describe the impairments of the thyroid function in patients with CSU in a third level of care.
Methods: A cross-sectional, observational, and descriptive study in which we have included men and women over 18-year-old with CSU; in which TSH and free T4 were quantified.
Background: Common variable immunodeficiency (CVID) is the most common primary symptomatic humoral immunodeficiency in adults. Antibody deficiency entails higher susceptibility to sinopulmonary infections and bronchiectasis formation, which is related to increased mortality. Scales have been established to assess the degree of severity of bronchiectasis in order to predict outcomes such as mortality, exacerbations and hospitalizations.

CVID diagnosis is by exclusion and should be considered in patients of any age who have hypogammaglobulinemia of unknown origin. Numerous patients with CVID show alterations in the development of B lymphocytes, both in plasma cells and memory cells.

The risk of systemic reactions is of 15-23 per 100,000 skin tests performed by prick method, specifically anaphylaxis at 0.02%.

Common variable immunodeficiency patients have a higher incidence of neoplasms, with a risk 12-18 times higher than the general population. There are few cases of common variable immunodeficiency patients with leukemia.
View Article and Find Full Text PDFBackground: Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by hypogammaglobulinemia. Its prevalence is 1:10000 to 1:50000 with the highest incidence in children, 6 to 10 years, and in adults around age 29. The association of CVID and bronchiectasis has a prevalence of 17-90%.

It has been suggested a possible association between vitamin D deficiency and increased risk and length of respiratory infections in patients with common variable immunodeficiency (CVID).
Methods: We conducted a descriptive study in patients with CVID.
