Chlamydia pneumoniae arthritis in a patient with common variable immunodeficiency.
BACKGROUND: Arthritis is an important and sometimes life-threatening complication in patients with common variable immunodeficiency (CVID). OBJECTIVE: To describe a patient with CVID and arthritis due to Chlamydia pneumoniae, which is usually regarded as a respiratory tract pathogen and has not previously been detected in the synovial fluid by cell culture technique. METHODS: Routine bacteriologic, virologic, mycologic, and tuberculosis cultures were performed. The patient's synovial fluid was examined for fastidious organisms that might be causative pathogens of arthritis, such as chlamydiae, and special cell culture methods were used. Serologic tests were performed to determine viral and bacteriologic etiology. RESULTS: The patient had a history of recurrent respiratory tract infections, and the latest exacerbation was followed by arthritis. Cytologic examination of the fluid yielded abundant lymphocytes. Chlamydia pneumoniae was detected in synovial fluid specimens by cell culture technique. Her nasopharyngeal swab and sputum culture specimens were also positive for this pathogen. She was diagnosed as having arthritis caused by C pneumoniae and was given antibiotherapy. CONCLUSION: Chlamydia pneumoniae should be kept in mind as a causative pathogen in patients with CVID and arthritis, especially when effusion fluid is full of lymphocytes rather than polymorphonuclear cells and no organism is grown on routine cultures.

Common variable immunodeficiency (CVID) presenting with malabsorption due to giardiasis.
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.

Vascular endothelial growth factor in gingival tissues and crevicular fluids of diabetic and healthy periodontal patients.
BACKGROUND: Periodontal disease is one of the major oral problems encountered in patients with diabetes mellitus (DM). Vascular changes, neutrophil dysfunction, altered collagen synthesis, and genetic predisposition observed in DM may contribute to periodontitis; and the vascular alterations observed in such patients may depend on vascular endothelial growth factor (VEGF) actions. Few reports are available about the mechanism of neovascularization and the angiogenic factors that contribute to the periodontal pathology and the role of VEGF in periodontal diseases. The aim of this study is to compare VEGF expression in healthy and periodontally diseased tissues with gingival crevice fluid (GCF) of healthy persons and diabetic patients. METHODS: Gingival tissue and GCF samples were collected from sites of periodontitis in 10 healthy subjects and in 10 type 2 diabetic patients, and from the sites of healthy gingiva within the same groups. Therefore, each patient became his/her own control. Additionally, 10 people without any systemic or periodontal diseases were enrolled, forming a negative control group. Thus, a total of 50 tissue and 50 GCF samples were provided. RESULTS: No VEGF staining was observed in the negative control group or in the systemically healthy people's healthy tissue samples, whereas four samples of diabetic patients showed positive staining (P < 0.05). However, VEGF was revealed in two tissue samples of periodontal sites of systemically healthy people and in six samples of the diabetic patients (P > 0.05). In all test groups, GCF VEGF levels were higher in periodontal sites (P < 0.05) than in healthy sites. CONCLUSION: The results of this study showed that VEGF is increased in all periodontal tissues of both groups and in the healthy sites of diabetic patients. Additionally, GCF VEGF values increased in periodontal sites of all test groups.

Elevation of serum eosinophil cationic protein, soluble tumor necrosis factor receptors and soluble intercellular adhesion molecule-1 levels in acute bronchial asthma.
Asthma is a disease characterized by chronic airway inflammation. Many inflammatory cells and molecules contribute to its pathogenesis. Soluble tumor necrosis factor receptors (sTNFRs) and soluble intercellular adhesion molecule-1 (sICAM-1) play regulatory roles in the inflammation. But their roles in the inflammation of asthma have not been well defined. This study was done to examine the changes in serum levels of these molecules in acute asthmatic patients. The concentrations of eosinophilic cationic protein (ECP), sTNF-RI, sTNF-RII, and sICAM-1 were measured in sera of 24 asthmatic patients during acute attack, in 18 patients at 24 h, and in 10 patients at 7 days after attack and in sera of 14 healthy control subjects by ELISA method. Serum levels of ECP, sTNF-RI, sTNF-RII and sICAM-1 in the patients with asthma during attack were significantly higher than those of the controls (p < 0.001, p < 0.01, p < 0.05, p < 0.05 respectively) and stayed high up to the 7th day. In conclusion, high serum levels of sTNF-RI, sTNF-RII and sICAM-1 suggest that these molecules may contribute to the regulation of allergic inflammation and may reflect the severity of inflammation in the airway of asthmatic patients.

Latex allergy and associated risk factors in a group of Turkish patients with spina bifida.
Allergic reactions to latex are common in patients with spina bifida. Its incidence varies between 28% and 67%. The aim of this study was to investigate the incidence of latex allergy and its risk factors in patients with spina bifida in Izmir, Turkey. Forty-six patients (24 male, mean age 10 years) were included in the study. A questionnaire was completed and skin prick tests with latex solution and cross-reacting foods were performed. Total IgE levels, specific IgE to common aeroallergens (Phadiotop), and latex specific IgE levels were measured. Patients with positive skin test reaction and/or who had specific IgE to latex without clinical symptoms were considered as sensitive to latex. The patients who also had clinical symptoms with latex exposure were diagnosed as allergic to latex. Latex sensitivity was found in 5/46 patients (10.8%). Only two patients had latex allergy (4.3%). Total IgE levels were higher (median 157 vs. 40 kU/L, p=0.012) and the duration of clean intermittent catheterization was longer insensitized patients when compared to non-sensitized patients (median 8 vs. 3 years, p=0.015). Specific IgE to common aeroallergens and positive skin prick test to cross-reacting foods were more prevalent in sensitized than in non-sensitized patients (p=0.02 and 0.015, respectively). The incidence of latex allergy in our group was lower than reported in the literature. This result may be due to the low number of surgical interventions. High levels of total IgE, positive Phadiotop, positive skin prick test to cross-reacting foods and the duration of clean intermittent catheterization are the risk factors for latex sensitivity in patients with spina bifida.
