The clinical-pathological characteristics of 11 patients with intestinal nodular lymphoid hyperplasia (INLH) are described. Five fulfilled the criteria for Herman's syndrome and presented all or several of the following alterations: dysgammaglobulinemia, recurrent respiratory tract infections, sinusitis, pneumonia and giardiasis; of the remaining six cases, in five gammaglobulin levels were not quantified and in one they were normal. All the patients in this group suffered from recurrent pharyngotonsillitis, and Giardia lamblia was isolated in four. In both groups the INLH occurred in young patients with an average age of 21 years. Eight of the 11 were men. The most frequent symptoms included diarrhea, steatorrhea and weight loss. Radiologically, INLH usually was a finding affecting the jejunum and/or the ileum. Prominent lymph nodes in mucosa and submucosa were documented histologically in all cases, and a large decrease or absence of plasma cells in the lamina propria was seen in 7 of the 11. In spite of the diversity in the treatment schemes instituted, symptoms persisted for months or years after diagnosis. In two cases (one with dysgammaglobulinemia and one without) associated intestinal lymphoma existed. Other associated diseases included non-deforming joint arthritis, erythema nodosum, and intestinal infection by E. coli and Entamoeba histolytica.

Common variable immunodeficiency is characterized with B-cell and T-cell dysfunction and hypogammaglobulinemia. Recurrent bacterial infections, such as otitis media, chronic sinusitis and recurrent pneumonia due to diminished immunoglobulin (Ig) levels and impaired antibody production are frequently observed in common variable immunodeficiency. Almost half of the patients with common variable immunodeficiency have problems related to the gastrointestinal system. A 39-year-old woman was referred to our department with the complaint of chronic diarrhea. She had experienced diarrhea without mucus or blood in the last year and had lost 30 kg. In her medical history, she had suffered from recurrent upper and lower respiratory infections like sinusitis, otitis media and pneumonia since childhood. Serum immunoglobulin levels were low. There were no parasites or ova in her stool examinations. Esophagogastroduodenoscopy detected widespread macroscopic nodular appearance on duodenum, and biopsies from the duodenum revealed giardiasis invading the tissue. She was diagnosed as common variable immunodeficiency. After metronidazole therapy and intravenous immunoglobulin infusion was started, her diarrhea attacks ceased and she regained her normal weight. Common gastrointestinal system problems in patients with common variable immunodeficiency are lactose intolerance, lymphoid hyperplasia/diffuse lymphoid infiltration, loss of villi and infection, especially with Giardia lamblia. Giardiasis may lead to severe mucosal flattening and sometimes to lymphoid hyperplasia at the lamina propria of the duodenum. Medical history should be evaluated carefully regarding recurrent respiratory infections. In such cases with chronic diarrhea, common variable immunodeficiency should be kept in mind as a possible cause.

Primary immunodeficiencies (PIDs) are a relatively common occurrence in countries where consanguineous marriages are widespread. A principal factor leading to misdiagnosis and ensuing complications can be the lack of knowledge and proper evaluation. The aim of this study was to assess PID awareness and the identification of diagnostic criteria leading to correct diagnosis. Seven hundred eighty-six questionnaires with 71 items were distributed to physicians attending the 41st National Congress of Pediatrics (2005) and to pediatric residents of two university hospitals from different cities in Turkey. The 217 completed questionnaires revealed that family history (91.2%), consanguineous marriages (87.1%), infant deaths (70.0%), persistent thrush (90.3%), hospitalization for recurrent cellulitis (70.5%), chronic diarrhea due to giardiasis (62.2%), recurrent oral aphthous lesions (58.5%), telangiectasia (82.0%), failure to thrive (78.8%), absence of tonsil tissue (74.7%), oculocutaneous albinism (73.7%), and resistant sinusitis (71.0%) were cited among important indicators of PID. However, neonatal tetany (77.9%), liver abscess (61.3%) and poliomyelitis following oral polio vaccination (51.2%) were not considered as related to PID. Although white blood cell (WBC) and differential were chosen as the preferred initial tests, leukocytosis and lymphopenia were also not judged as related to PID. More comprehensive pre/postgraduate education in PID appears to be necessary for physicians in Turkey.
