ABSTRACT

Serum samples, 100 in the total number, were collected from different laboratories in Tehran, Iran and tested for anti-Toxoplasma specific IgG and IgM antibodies using indirect immunofluorescent antibody test (IFAT). Using the IgG (chronic) and IgM (acute) positive samples, the IgG avidity test was performed by ELISA in duplicate rows of 96-well microtiter plates. One row was washed with 6 M urea and the other with PBS (pH 7.2), then the avidity index (AI) was calculated. Sixteen out of 18 (88.9%) sera with acute toxoplasmosis showed low avidity levels (AI60). Six sera had borderline ranges of AI. The results showed that the IgG avidity test by ELISA could distinguish the acute and chronic stages of toxoplasmosis in humans.

ABSTRACT

BACKGROUND: The purpose of this stady is to define the clinical characteristics of Tsutsugamushi disease. METHODS: We analyzed 12 cases of tsutsugamushi disease admitted to BAG AE general hospital from 1999. Oct. 1st to Dec. 10. Tsutsugamushi disease was diagnosed by indirect immunofluorescent antibody test. RESULTS: 1) Among them, 8 cases were female and 4 cases were male. The prevalence was predominantly high in female. 2) The age distribution ranged from 40 to 80 years old. The high incidence of age was 70's and 80's. 3) The peak incidene was showed between October and November.(91.6%). 4) The most frequent symptoms were fever and chills(91.6%). 5) Rash and eschar were observed in 83.3%(10 of 12) both. 6) Hepatosplenomegaly and lymphadenopathy were also observed in 25%(3 of 12), 16.6%(2 of 12) respectively. 7) The Laboratory finding showed the elevation of AST 66.6% (8 of 12), ALT 58.3%(7 of 12), alkaline phosphatase 25%(3 of 12) and LDH 25%(3 of 12). Albuminuria and hypoalbuminuria were also observed in 25%(3 of 12), 58.3%(7 of 12) respectively. 8) The therapeutic efficacy of doxycycline was excellent. CONCLUSION: Tsutsugamushi disease which appeared in Pyoungtack area showed typical clinical pattern and was effective to doxycycline treatment.

ABSTRACT

Herpes simplex virus keratits(HSK) is one of the most common external eye diseases that cause corneal blindness, Therefore early diagnosis and proper treatment of HSK are essential. However it is frequently misdiagnosed because it shows non-specific corneal lesion than other infectious corneal disease. And also diagnosis of HSK mostly rely on clinical examination and patient history. We evaluated suspicious HSK patients by indirect immunofluofluorescent(IF) antibody test and analyzed its efficacy in the early diagnosis of HSK. Among 47 patients(47 eyes), 37 patients were suspicious heretic keratitis and others not. Dendritic keratitis patients existed in 17 out of 37 patients and they were evaluated with virus culture and indirect IF test. The result of indirect IF test was confirmed under the immunofluorescent microscope and for virus culture the specimens were inoculated on Vero cells(monkey kidney cells). The positive results of indirect IF test was 28 out of 37 suspicious HSK patients and 1 out of 10 non-suspicious HSK patients. Dendritic HSK patients showed IF positive in 15 out of 17 patients(82.3%). Sensitivity of indirect IF test in suspicious HSK patients was 75.7%(2837) and 88.2%(15/17) in dendritic HSK patients. Indirect IF test was all positive(14/14) in dendritic HSK patients that showed culture positive. From these results, indirect IF test has a high sensitivity in early diagnosis of HSK and might be ussful as a rapid diagnostic tool in HSK patients.

ABSTRACT

Tsutsugamushi disease is an acute febrile disease caused by Rickettsia tsutsugamushi, and which has been reported with increasing frequency thorough the nation since 1986. We experienced 21 cases of Tsutsugamushi Disease diagnosed with serologic test occurring in Taegu city and Kyungpook province during October-November, 1989. The results of survey are as follow. 1) Of 21 cases, 12 (57%) were males and 9 (43%) were females, and the peak incidence was the 4th decade. 2) The outbreak was in October to November and the peak incidence was in October. 3) The most frequent symptoms were fever and chill (100%), myalgia (95%), headache (90%), Eschar and rash were observed in 18 patients (86%) and the eschar was detected in all over the body, especially thorax (33%) and lower extremity (22%). 4) Laboratory features were SGOT elevation (83%), SGPT elevation (61%), LDH elevation (67%), leukocytosis (38%). 5) Indirect immunofluorescent antibody test was done in 18 patients and the antibody titer was above 1:320 in all patients. 6) The chloramphenicol, tetracycline or doxycycline regimens were very effective and mean duration of defervescence from initiation of therapy was 1.3 days. 7) The complication such as meningitis or shock, was not seen.
