A 13-month-old girl presented with right upper lobe pneumonia and hypocalcaemic seizures: investigations showed hypoparathyroidism and impaired cell-mediated immune responses. Other features of the DiGeorge syndrome included hypertelorism, short philtrum of the lip, right-sided aortic arch, and aberrant origin of the left subclavian artery. Successful restoration of the immunodeficiency was achieved by transplantation of fetal thymic epithelium.

A patient with DiGeorge syndrome developed pneumonia caused by para-influenza virus type 3 two years after immunological reconstitution with foetal thymic eptihelium. There was a transient reduction of mitogen-induced lymphocyte transformation at the time of the pneumonia. Although she recovered from the pneumonia, brochitis persisted and the virus could still be isolated from her pharyngeal secretions 3 1/2 months later.

Antibodies directed to capsular polysaccharides form an essential component in the defence against infections with encapsulated bacteria such as Streptococcus pneumoniae and Haemophilus influenzae type b. Immune responses to polysaccharide antigens can occur in the absence of a functional thymus and the antigens are therefore designated as thymus independent. However, regulatory T cells may influence the magnitude of the antibody response to capsular polysaccharide antigens. So-called thymus independent type 2 antigens share several features of their immune response such as late development of antibody synthesis in ontogeny, no memory formation and a restricted isotype (IgM, IgG2) and idiotype usage. In infants and young children up to the age of 2 years the antibody response to capsular polysaccharides is inadequate resulting in an increased incidence of diseases such as pneumonia, meningitis, otitis and other forms of bacteremic disease. Anti-capsular polysaccharide antibody deficiency does occur in a number of well defined immunodeficiency syndromes including hypo- or agammaglobulinaemia, selective IgA and/or IgG subclass deficiency, Wiskott-Aldrich syndrome, DiGeorge anomaly and also in acquired immune deficiencies such as AIDS, and some forms of lymphoid malignancies. In elderly and in conditions such as splenectomy an increased incidence of infections with encapsulated bacteria does occur, sometimes but not always on basis of a defect in antibody formation. Clinicians are often confronted with young patients older than 2 years of age suffering from recurrent severe bacterial infections of the respiratory tract. In these patients no overt immunodeficiency is demonstrable but recent results indicated that a small percentage may show a selective defect in the antibody response since upon vaccination with polysaccharide vaccines no increase in antibody titer does occur. Though antibodies to polysaccharide antigens in young children are mainly of the IgM and IgG1 (IgG3) isotype, in older children and adults the polysaccharide antibodies are predominantly localized in the IgG2 subclass. The bridge between IgG2 type antibodies and phagocytosis of encapsulated bacteria is constituted by Fc gamma receptors for IgG2 on effector cells. The recent finding that allotypes of Fc gamma RIIa do exist that either bind or do not bind IgG2 type antibodies strongly suggests that the defence of a given individual to encapsulated bacteria apart from an intact antibody formation and the complement system also is determined by the allotype of the appropriate Fc gamma receptor.(ABSTRACT TRUNCATED AT 400 WORDS)

We report an infantile male case of ASD, VSD and PDA associated with DiGeorge syndrome. The patient who was 58-day old presented the partial deficiency of cell-mediated immunity and normocalcemia before the admission to our hospital. We made semi-emergent operation because of increasing of lung congestion caused by repetitional infection of upper respiratory tract. Direct closure of the ASD, patch closure of the VSD and ligation of the PDA were performed successfully. He was suffered from severe pneumonia caused by MRSA in early postoperative stage. It was effective to give antibiotics and gamma-globulins.

A female infant presented with cyanosis, respiratory distress and unique to-and-fro murmur which she had since the age of 1-month-old. Absent pulmonary valve syndrome was diagnosed by echocardiography. She developed seizure disorders with hypocalcemia and pneumonia at the age of 2-month-old. The patient died from sepsis, intractable respiratory and heart failure. The postmortem study confirmed the diagnosis of congenital absent pulmonary valve associated with DiGeorge syndrome.

Pulmonary disease is a common presenting feature and complication of T-cell immunodeficiency. We retrospectively reviewed 15 children with severe combined immune deficiency (SCID) and 19 children with DiGeorge syndrome at the time of their first presentation to the Royal Children's Hospital in the 15-year period from 1981 to 1995. In children with SCID, pulmonary disease was a common (67%) presenting feature and the organisms identified were Pneumocystis carinii (PCP) (n = 7), bacteria (n = 4), viruses (n = 3), and a fungus (n = 1). Late pulmonary complications included lower respiratory tract infections, bronchiolitis obliterans, and lymphointerstitial pneumonitis. Pulmonary infections were common (17 occasions) and the organisms identified were bacteria (n = 7), viruses (n = 6), fungi (n = 3), and Mycobacterium tuberculosis (n = 1). Pulmonary complications were responsible for 5 of 9 deaths. PCP was not identified as a late complication in any child, presumably as a result of effective prophylactic therapy. Although pulmonary disease was not a major presenting feature in children with DiGeorge syndrome, pulmonary complications were common. These included recurrent bacterial and viral infections and bronchomalacia, which complicated management and predisposed to morbidity and mortality, even in those without a T-cell defect. We conclude that pulmonary disease is a common manifestation in children with SCID and DiGeorge syndrome.

We report a case of pneumonia in a 13 month old male child with partial DiGeorge syndrome who died after inadvertently receiving live viral vaccines. Although live viral vaccines have been used safely in some children with DiGeorge syndrome, there are insufficient data to recommend their routine use in those with severe immunodeficiency.

A 32-year-old male with CATCH22 syndrome presented with a high fever and productive cough after taking drugs for acute bronchitis, including (L)-carbocisteine. Chest radiography revealed ground-glass opacities in the bilateral lung fields. He had a history of similar pneumonia. Under the assumption of drug-induced pneumonia, or bacterial or viral pneumonia, all drugs including (L)-carbocisteine were discontinued, and antibiotics were started. A drug-induced lymphocyte stimulation test was positive only for (L)-carbocisteine. The only drug in common between this and the previous episode of pneumonia was (L)-carbocisteine. We thus concluded that this was a definite case of (L)-carbocisteine-induced pneumonia in a patient with CATCH22 syndrome.

A 34-year-old man with 22q11.2 deletion syndrome (DiGeorge syndrome) concurrently suffered from myopathy and eosinophilic pneumonia shortly after receiving daptomycin (DAP) for right-sided infective endocarditis. The simultaneous occurrence of these phenomena in relation to DAP therapy has not been previously well described. An allergic reaction was suspected as a possible etiology of these DAP-related complications. This case highlights the need for close observation in order to detect both musculoskeletal and respiratory disorders from the start of DAP therapy. Physicians should pay more attention to this new drug, which is expected to be frequently used in various clinical settings.
