RESUMO

CONTEXT: Adhesion molecule deficiency type 1 is a rare disease that should be suspected in any patient whose umbilical cord presents delay in falling off, and who presents recurrent severe infections. Early diagnostic suspicion and early treatment improve the prognosis. CASE REPORT: The case of a four-month-old boy with recurrent hospitalizations because of severe bronchopneumonia and several episodes of acute otitis media with non-purulent drainage of mucus and positive bacterial cultures is presented. His medical history included neonatal sepsis and delayed umbilical cord detachment. Laboratory studies showed marked leukocytosis with predominance of neutrophils and decreased CD11b and CD18. These were all compatible with a diagnosis of leukocyte adhesion deficiency type I [LAD type 1].


CONTEXTO: El deficit de moleculas de adhesión tipo 1 es una enfermedad rara que debe ser sospechada en todo paciente que presente un retardo en la caída del cordón unmbilical, además de infecciones graves a repetición. Un sospecha diagnóstica precoz y un tratamiento oportuno mejorarán el pronóstico. INFORMES DE CASO: Se presenta el caso de un niño de cuatro meses de edad, con hospitalizaciones recurrentes a causa de bronconeumonía severa y varios episodios de otitis media aguda con drenaje mucoso, no purulento, y cultivos bacterianos positivos. Su historial médico incluye la sepsis neonatal y el desprendimiento tardío del cordón umbilical. Los estudios de laboratorio mostraron leucocitosis marcada con predominio neutrofílico y disminución de CD11b y CD18, todos compatibles con el diagnóstico del tipo de deficiencia de adhesión leucocitaria 1 [tipo LAD 1].

RESUMO

Leucocyte adhesion defect (LAD) is an inherited disorder of phagocytic function. It is characterized by inability of the leucocytes, in particular neutrophilis to migrate from the blood stream towards sites of inflammation. LAD -1 is characterized by the absence of b 2 integrins (CD 11 / CD18) on leucocytes. This disorder is characterized by delayed separation of the umbilical cord, recurrent severe infections, periodontitis, and delayed wound healing. We report an infant where the diagnosis was confirmed by flow cytometry.

RESUMO

OBJECTIVE: To report various primary immune deficiencies diagnosed in children at a tertiary care hospital, their clinical manifestations and laboratory profile. METHODS: Case records of children diagnosed to have primary immunodeficiency disorders over a period of 24 months at a tertiary care hospital in northern India were evaluated. RESULTS: Twenty-seven children (M: F=3.5: 1) with mean age of 5.4 +/- 4.6 yrs (2 mo-16 yr) were diagnosed to have primary immunodeficiency. Thirteen children had chronic granulomatous disease (CGD), 4 had severe combined immunodeficiency (SCID), 4 had hypogammaglobulinemia, 2 had Ataxia telangiectasia, and one each had DiGeorge syndrome, Wiskott Aldrich syndrome, hyper IgM syndrome and leukocyte adhesion defect. Common mode of presentation were recurrent/ persistent pneumonia in 19, recurrent/ persistent diarrhea in 10, deep seated abscesses in 8, allergy in 3, disseminated tuberculosis infection in 2, extensive fungal infections in 2 and 1 each of disseminated cytomegalovirus (CMV) infection, disseminated BCG disease, otitis media and meningitis. Family history of sibling deaths was elicited in 2 families. Infectious agents were isolated in 16 cases. CONCLUSION: From a single center 27 patients with primary immune deficiency could be identified by chart review, suggesting need for high index of suspicion for diagnosis of primary immune deficiency in India. Though the exact prevalence is not known there is need to make a registry to document the magnitude of problem of these disorders.

RESUMO

Leukocyte Adhesion Deficiency (LAD) is characterized by the inability of leukocytes, in particular neutrophilic granulocytes, to emigrate from the blood stream towards sites of inflammation. Infectious foci are nonpurulent and may eventually become necrotic because of abnormal wound healing. LAD-I is characterized by the absence of the beta-2 integrins CD II and CD 18 on leukocytes. We present a male neonate referred with continuation of leukemoid reaction in spite of antibiotic therapy of simultaneous omphalitis. The diagnosis of LAD-I was confirmed by flow cytometry, showing a deficiency of beta-2 integrins on the surface of the leukocytes. After management, the patient was discharged with prophylactic antibiotics.
