Abstract
Serological Widal test is a fast, reliable and easy to perform and this test still is a suitable diagnostic method for diagnosing of typhoidal disease in many clinical laboratories. However, there are some doubtful reports regarding diagnostic value and credibility of this test, which was a motivation for present research. In this study, a total of 378 patients in two groups including 182 typhoidal patients with positive culture for Salmonella Typhi and para-Typhi A, B, C and 196 non-typhoidal febrile patients with negative culture for Salmonella, were studied in Hamadan city during 1994-97. All patients had at least one Widal test. In first group, 52.7% of patients have a titer of ?1:40 using anti-O (A, B, D) and 42.3% of patients also have a titer of ?1:80 using anti-O (A, B, D). In second group, 7.2% of patients have a titer of ?1:40 and 5.6% of them have a titer of ?1:80. In first group, 66.4% of patients had positive blood culture for S.typhi, however, 31.3% of them had positive antibody for OD titer. The results of this study indicated that sensitivity of Widal test for titer of ?1:80 was 86%, specificity 64% and PPV 42% and NPV 95%, therefore the negative Widal test did not have significant effect on the clinical diagnosis of typhoid disease.

Materials and Methods: In this case – control study, fifty hospitalized patients with definite diagnosis of typhoid fever in Razi and Abuzar hospitals in Ahwaz were investigated. For each patient, one subject was matched with age, sex and socioeconomic characteristic as control. All of the case and control were tested for IgG –anti helicobacter pylori by ELISA method. Data were analyzed by chi squared test in SPSS software.
Results: Seroprevalence of helicobacter pylori in case (66%) was higher than control (44%) (p<0.05). There was a significant difference between patients and control in male (p<0.05), but not in female.
Conclusion: This study indicated that typhoid fever is associated with helicobacter pylori co-infection in this region.
