Background: Intravenous immunoglobulin (IVIG) is the treatment of choice for humoral primary immunodeficiency diseases (PIDs). A third of the patients who receive intravenous immunoglobulin have adverse reactions, such as osmotic nephrosis. Objective: To assess the presence of kidney disease in adults with humoral PIDs, in treatment with intravenous immunoglobulin. Methods: A cross-sectional, descriptive, and observational study of patients who belong to the PID Clinic of the Specialties Hospital of the National Medical Center "Siglo XXI", Mexico City, who receive treatment with intravenous immunoglobulin. A questionnaire with demographic information, 24h urine creatinine clearance, serum creatinine, urea, and BUN (Blood Urea Nitrogen) was applied. Results: 35 patients were surveyed; 65.7 % were women; the average age was 34 years; 51.4 % of the patients presented kidney damage. Those with > 5 years of treatment with intravenous immunoglobulin presented chronic kidney disease (CKD) with more frequency (55.6 %) according to the KDOQI scale. Conclusions: Chronic kidney disease occurs in 51 % of adult patients with PID who have been treated with intravenous immunoglobulin for more than 5 years; which is why these patients require periodic evaluations of their kidney function, and the use of sugar-free immunoglobulin in order to reduce the risk.

Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency in adulthood. 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 absence of memory B cells suggests an insufficient germinal reaction, which can be associated with a blockade of the transition of T1 cells into T2 in patients with IDCV, owing to B-cell activating factor (BAFF) receptor deficiency. In patients with IDCV, memory B cell alterations with isotype change favor the development of concomitant comorbidities such as lymphadenopathy, splenomegaly, autoimmunity and granulomatous disease, and multiple classifications that use memory B cells in common have therefore been made trying to generate a classification of patients with IDCV, as well as to establish prognostic factors.

Background: common variable immunodeficiency is a primary immunodeficiency, in which from 70 to 80% of patients have tumors and 25% of cases are associated with autoimmune diseases. 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. Clinical case: female of 36 years old, with left upper quadrant pain, early satiety, weight loss of 8 kg in three months and splenomegaly. The complete blood count showed: leukocytosis 206 000/µL, with 8% blasts, platelets 530 000/µL and hemoglobin 8 mg/dL. Abdominal ultrasound: 19x12 cm splenomegaly. Karyotype BCR/ABL IS 64.20%, 100% Philadelphia chromosome. The diagnosis was of chronic myeloid leukemia. Given the presence of recurrent respiratory tract infection, frequent diarrheas and reduced concentrations of IgG, IgM and IgA, common variable immunodeficiency was diagnosed and human immunoglobulin was used successfully. Conclusions: the association between chronic myeloid leukemia and common variable immunodeficiency is unusual. Given the high frequency of hematological neoplasm in common variable immunodeficiency patients, we suggest that hematological patients with repeated infections and decreased concentrations of immunoglobulin be referred to an immunological evaluation.

Background: Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by defective immunoglobulin production. Twenty percent of patients may also have associated autoimmune diseases, especially hematologic, whose prevalence is estimated at 5 to 8%. Objective: To report the occurrence of autoimmune haematological disorders in CVID adults. Methods: We included 18 patients with CVID, who underwent hematologic evaluation, which included: CBC, serum folate or vitamin B complex and bone marrow aspirate. Results: Of a total of 18 patients, 11 women (61%), mean age 38 ± 13.5, six patients (33.3%) had autoimmune diseases, five of them had blood diseases (4 with PTI and one with Evans syndrome). Three patients had more than one autoimmune disease and one presented three autoimmune diseases (Evans syndrome, hypoparathyroidism and celiac disease with a history of autoimmune hemolytic anemia). Conclusions: The prevalence of autoimmune diseases in this group of patients with CVID was higher than the 20% reported in the literature. Hematological diseases should be suspected in CVID patients, since half of our cases presented them. [ABSTRACT FROM AUTHOR]
