Selective IgM deficiency: evaluation of 75 patients according to different diagnostic criteria.

Selective IgM deficiency (SIgMD) has recently been included in the inborn errors of immunity classification. SIgMD has conflicting diagnostic criteria and diverse clinical and immunological findings. We aimed to assess the clinical and laboratory profiles of patients with SIgMD and to compare the data of patients diagnosed using two inclusion criteria.

Behçet disease in a child--emphasis on cutaneous manifestations.

The diagnosis of Behçet disease is based upon clinical criteria because of the lack of pathognomonic laboratory findings. Recurrent episodes of oral and genital ulcerations, skin lesions, and ocular manifestations are seen. The disease may also involve the central nervous system, gastrointestinal tract and, less frequently, the large vessels.

Insulin-like growth factor-1, leptin, body composition, and clinical status interactions in children with cystic fibrosis.

Background/aims: Children with cystic fibrosis (CF) are of increased risk of reduced fat body mass (FBM) and lean body mass (LBM). Serum concentrations of insulin-like growth factor-1 (IGF-1)and leptin could be markers of LBM and/or FBM depletion. To evaluate the relationships between disease activity, body composition, IGF-1 and leptin concentrations in CF children.
