[T-lymphocyte subgroups and tuberculin skin test reactivity in patients with chronic renal failure].
As anergy is common in patients with chronic renal failure (CRF), the use of tuberculin skin test (TST) is controversial. Therefore, determination of the factors that affect the TST reactivity would increase the diagnostic value of the test. The aim of the present study was to investigate the factors affecting TST reactivity and evaluate the relationship between T-lymphocyte subsets and TST reactivity. We thus examined 44 patients (mean age 46.6 +/- 15.6 years, 25 males, duration of CRF 5.6 +/- 5.2 years), performed TST (an induration with a diameter of 5 mm or more was considered as positive) and measured Tlymphocyte subsets and biochemical parameters. Twenty-three patients were on hemodialysis, six were on peritoneal dialysis, seven were transplant recipients, and eight were on medical treatment. Eleven patients (25%) had immunosuppressive treatment. Eleven patients (25%) had two, 29 patients (66%) had one, and four patients (9%) had no BCG scars. Five patients (11%) had low body mass index (BMI). T-lymphocyte subsets were as follows: CD4= 40.7 +/- 7.6%, CD8= 32 +/- 8.9%, CD4/CD8= 1.7 +/- 2.5%, CD3= 71.4 +/- 9.4%, CD19= 6.3 +/- 5.1%, NK= 9.7 +/- 5.9. Twenty-two patients had positive TST reactivity. No relation was found between TST reactivity and age, gender, co-morbidity, BCG vaccination, BMI, immunosuppressive therapy, duration and treatment of CRF. Similarly, TST reactivity was not related to the biochemical parameters and Tlymphocyte subsets. These data provide that tuberculin reactivity does not seem to be associated with T-lymphocyte dysfunction and clinical features in patients with chronic renal failure.

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.
