Primary immunodeficiencies are generally determined and can present early or at birth as opposed to acquired infections which present later. [pedclerk.bsd.uchicago.edu]

Clinically, CVID patients may present similarly to patients with XLA. Certain atypical XLA varieties with a delayed presentation are known to mimic CVID. [hindawi.com]

The disorder presents clinically as marked susceptibility to infections, severe malabsorption and failure to thrive and is often fatal in early childhood. [orpha.net]

For example, severe T-cell or combined immune deficiencies typically present in infancy. However, some antibody deficiencies may present in older children or adults. [aaaai.org]

Presentation The most common presenting feature is frequent infections. [patient.info]

• Recurrent Infection

  Underlying factors of recurrent infections in patients with down syndrome [North Clin Istanb] North Clin Istanb. 2018; 5(2): 163-168 | DOI: 10.14744/nci.2017.69379 Underlying factors of recurrent infections in patients with down syndrome Turkan Patiroglu [kuzeyklinikleri.com]

  ZAP-70 deficiency causes recurrent infections similar to those in severe combined immunodeficiency (SCID) in infants and young children. However, the deficiency may not be diagnosed until children are several years old. [msdmanuals.com]

  SCID patients are usually diagnosed in the first year of life with symptoms such as recurrent infections and failure to thrive. [immunology.org]

• Splenomegaly

  Low lymphocyte counts could not be assigned to splenomegaly and hypersplenism because counts remained lower than those observed among patients with CVID with splenomegaly (data not shown). [academic.oup.com]

  Hepatomegaly and splenomegaly may be detected in the abdomen. In infants, crusting around the anus may be a sign of chronic diarrhoea. Delayed developmental milestones or ataxia may be evident. [patient.info]

  On physical examination, patients with this subtype often have splenomegaly and bronchiectasis. [emedicine.medscape.com]

  A 41-year-old female with poor adherence to antiretroviral therapy was admitted to hospital with nonspecific symptoms; an abdominal computed tomography (CT) scan revealed substantial ascites, splenomegaly, and lymphadenopathy. [ekjm.org]

  Due to abnormalities in the maturation of B cells, and dysregulation of the immune system, some individuals with CVID may have abnormal accumulations of lymphocytes in lymphoid tissues such as lymph nodes (lymphadenopathy) or spleen (splenomegaly). [rarediseases.org]
