Skin hyperreactivity of Behçet's patients (pathergy reaction) is also positive in interferon alpha-treated chronic myeloid leukaemia patients, indicating similarly altered neutrophil functions in both disorders.

Typical manifestations of Behcet's disease (BD) and a positive pathergy reaction were observed in a few patients with chronic myeloid leukaemia (CML) on interferon alpha (IFN-alpha) therapy and the significance of this observation was assessed in a prospective study. The skin pathergy test was applied to 15 patients with CML prior to IFN-alpha therapy, 29 patients with CML following IFN-alpha therapy and 30 patients with BD. Twenty-five patients with inflammatory arthropathies (IA), 20 patients with recurrent oral ulcers (ROU), 23 patients treated with IFN-alpha for various disorders and 20 normal individuals were also studied as control groups. The pathergy reaction was positive in nearly a quarter of IFN-alpha-treated CML cases (24%) as well as one-half of the patients with BD (50%). All CML patients prior to IFN-alpha treatment and all patients using IFN-alpha for other diseases were negative for the pathergy reaction. These results may indicate a similarly altered neutrophil function in both BD and IFN-alpha-treated CML patients.

Therapeutic efficacy of recombinant interferon-alpha in polycythaemia vera.

The therapeutic efficacy of recombinant interferon-alpha (rIFN-alpha) has been evaluated in 7 patients with polycythaemia vera (PV), diagnosed according to the criteria of the Polycythemia Vera Study Group. Six complete responses and one partial response were achieved. Pruritus significantly improved in 80% (4/5) of the cases. Recombinant interferon-alpha had to be discontinued in 1 patient because of grade 3-4 nephrotoxicity according to WHO criteria. rIFN-alpha therapy significantly decreased the phlebotomy requirements and improved the mean corpuscular volume, erythrocyte and platelet counts, pruritus complaints and the degree of splenomegaly (p < 0.05). rIFN-alpha seems to be an effective treatment modality for the myeloproliferation of PV and pruritus complaints.

Sample adequacy in detecting Chlamydia trachomatis.

OBJECTIVE: Chlamydia trachomatis is an important etiological agent in female genital infection and may result in infertility. In recent years rapid diagnostic methods have become widely used as alternatives to cell culture. Our objective was to evaluate the technique of direct fluorescence assay (DFA) in estimating the presence of C. trachomatis. METHODS: Specimens taken from 40 infertile and 20 fertile women were examined by DFA for the presence of C. trachomatis. RESULTS: Six of forty (15%) infertile women were found to be positive whereas no positive specimens were detected in the control group. When the specimens were grouped into those which were adequate or inadequate, 19 and five specimens, respectively, were adequate in the infertile and healthy groups. If only adequate specimens are included in estimating the presence of Chlamydia, the percentage is 31.6%. CONCLUSIONS: In order to use DFA as a more reliable and rapid diagnostic test of C. trachomatis in female genital infection, false-negativity must be eliminated. Specimens must be collected adequately and concentrated in order to achieve optimal diagnostic success.

Seroprevalence of rubella virus in Turkish pregnant women.

OBJECTIVES: To assess the immune status of a group of Turkish pregnant women who had never been immunized. METHODS: Between June 1990 and April 1993, the seroprevelance of rubella was determined in the study group of 1351 women. RESULTS: A total of 242 (17.9%) pregnant women were found to be susceptible to rubella infection and the seropositivity rate related to prior infection was 82.1%. CONCLUSIONS: The importance of Rubella IgG determination in Turkish pregnant women is discussed and recommendations for prevention and control of congenital rubella syndrome (CRS) are suggested.
