Cytokine response in crimean-congo hemorrhagic fever virus infection.

We described the predictive role of cytokines in fatality of Crimean Congo Hemorrhagic Fever Virus (CCHFV) infection by using daily clinical sera samples. Consequent serum samples of the selected patients in different severity groups and healthy controls were examined by using human cytokine 17-plex assay. We included 12 (23%) mild, 30 (58%) moderate, 10 (19%) severe patients, and 10 healthy volunteers. The mean age of the patients was 52 (sd 15), 52% were female. Forty-six patients (88%) received ribavirin. During disease course, the median levels of IL-6, IL-8, IL-10, IL-10/12, IFN-γ, MCP-1, and MIP-1b were found to be significantly higher among CCHF patients than the healthy controls. Within the first 5 days after onset of disease, among the fatal cases, the median levels of IL-6 and IL-8 were found to be significantly higher than the survived ones (Fig. 3), and MCP-1 was elevated among fatal cases, but statistical significance was not detected. In receiver operating characteristic (ROC) analysis, IL-8 (92%), IL-6 (92%), MCP-1 (79%) were found to be the most significant cytokines in predicting the fatality rates in the early period of the disease (5 days). IL-6 and IL-8 can predict the poor outcome, within the first 5 days of disease course. Elevated IL-6 and IL-8 levels within first 5 days could be used as prognostic markers.

Epidemiologic and clinical characteristics of HIV/AIDS patients in Turkey, where the prevalence is the lowest in the region.

The authors describe the epidemiologic and clinical characteristics of 97 human immunodeficiency virus (HIV)-infected patients, who were followed between 1993 and 2006. Seventy-two percent of the patients were male, and median age at diagnosis was 36 years (range, 13-71 years). The mean years of survival was 3, and maximum length of life after diagnosis was 9 years. The most common professions were truck drivers, workers, and housewives. Forty-six percent of the males had a history of working abroad. Heterosexual intercourse was the most common (84%) route of transmission. Seventy-four percent of the women acquired infection from their husbands. In Turkey, less educated or uneducated and poor men are the primary target of the HIV infection usually by sexual contact with foreign women. Considering the low education status of the patients, appropriate education programs should be developed to prevent the dissemination of HIV infection. Because a significant number of patients were diagnosed at very late stages, the physicians and other health care workers should be educated on the clinical pictures of HIV/AIDS.

Measles, rubella, mumps, and varicella seroprevalence among health care workers in Turkey: is prevaccination screening cost-effective?

BACKGROUND: To investigate the immune status of health care workers (HCWs) against measles, rubella, mumps, and varicella zoster (MMRV) in Turkey and to define an appropriate vaccination program among HCWs. METHODS: Voluntary HCWs from a children's hospital and a general hospital were included in the study between March and May 2005. The specific IgG antibodies against MMRV viruses were screened by ELISA. RESULTS: Three hundred sixty-three HCWs participated in the study; 186 (51%) were physicians, 118 (33%) were nurses, 36 (10%) were housekeeping staff, and 23 (6%) were medical technicians. The proportion of HCWs who had antibodies against measles was 98.6%; rubella, 98.3%; mumps, 92.2%; and varicella, 98%. No association was found between the susceptibility to at least 1 of MMRV virus infections and gender, age, duration of work, profession, and department of work in analysis either among the whole study group, or each hospital. The positive predictive value for the history of varicella was 100%, whereas it was 92% for MMR. The cost of vaccination for varicella was significantly expensive without screening before vaccination. However, there was not much difference for MMR infections. CONCLUSION: A policy based on obtaining the history of varicella infection from the staff and then screening the ones with negative history and vaccination of only seronegative HCWs was found to be appropriate.

[Malaria in Turkey and 14 years of clinical experience]. / Turkiye'de sitma ve 14 yillik klinik deneyimimiz.

In this retrospective study, the epidemiologic and clinical characteristics of 105 adult malaria patients, who had been hospitalized between the period of 1992 and 2006 were evaluated. Nineteen percent of the patients were female, and the mean age was 28 +/- 10 years. Fifty percent of the patients acquired the infection in Southeastern Anatolia, while they were on military duty. The most common complaints were rigor (93%), fever (90%), sweating (90%), headache (76%), nausea (45%), and fatigue (38%). The most common physical examination findings were splenomegaly (86%) and hepatomegaly (62%). Anemia was detected in 23%, leukopenia in 47%, thrombocytopenia in 73%, two fold increase in ALT or AST enzyme levels in 32% of the patients. Plasmodium vivax was detected in 101 (96%) patients, whereas P. falciparum was detected in 4 patients (4%). Although the number of malaria cases in Turkey is declining in recent years, the febrile patients with a history of travel to the endemic regions should raise the suspicion of malaria.

Characteristics of B. melitensis versus B. abortus bacteraemias.

OBJECTIVE: To determine the epidemiological and the clinical characteristics of bacteremic brucellosis. METHODS: A prospective study, performed in the First Infectious Diseases Clinic of Ankara Numune Education and Research Hospital. All the patients had positive culture result for Brucella spp. RESULTS: Fifty-four acute bacteremic brucellosis cases were included. The majority of patients (76%) were from rural Anatolia. Brucella melitensis serotypes were more common than Brucella abortus (83% versus 17%). Fever and arthralgia were the most common symptoms. The number of patients with back pain and arthralgia was higher in B. abortus infected group (p = 0.014 and p = 0.009). CONCLUSIONS: B. melitensis is the most common subtype of Brucella infection in Turkey. The infections with B. abortus spp. are not less severe than the infections with B. melitensis.

Crimean Congo hemorrhagic fever infection simulating acute appendicitis.

An unusual cause of acute abdominal pain simulating acute appendicitis is presented. The patient was admitted with complaints of fever, malaise, headache, nausea, vomiting, diarrhoea, and severe bleeding. Based on the clinical and epidemiological findings, a diagnosis of Crimean Congo hemorrhagic fever virus infection was suspected, and ribavirin therapy was started. While her clinical condition was improving, she experienced a sudden pain at her right lower quadrant of the abdomen. Explorative laparotomy revealed haemorrhage within the abdominal muscles. Her CCHF IgM was found to be positive.

[Two leptospirosis cases and review of the national literature]. / Iki leptospiroz olgusu ve yerli literatürün gözden geçirilmesi.

In this report, two cases of leptospirosis admitted to our clinic in the same periods, have been presented. The first patient was a 29 years old male farmer, and the other was a 44 years old male prisoner. Both of them were from Middle Anatolian Region with the similar clinical findings (subfebrile fever, gastrointestinal complaints, ichterus in sclera, leucocytosis, and increased levels of liver enzymes, urea and creatine). The diagnosis was based on the antibody positivities against Leptospira with microscopic agglutination test which performed in the Etlik Central Veterinary Control and Research Institute. The first case was positive for L. grippotyphosa, and the second was positive for L. australis serovar bratislava at the titers of 1/800. Both of the patients were given empirical antibiotic treatment (ceftriaxone 2 x 1 gr, and ampicillin-sulbactam 4 x 1 gr, respectively), and discharged with complete healing. These cases led us to review the other leptospirosis cases in our country.

[Case report: cutaneous tuberculosis and tuberculous osteomyelitis]. / Olgu sunumu: deri tüberkülozu ve tüberküloz osteomiyeliti.

In this report, a 27 years old male patient diagnosed to have skin and bone tuberculosis (TB) has been presented. The patient admitted to the hospital with the complaints of fever, weight loss and night sweats. Patient's history revealed that following a trauma a skin lesion in the right ankle was developed and this was followed by the development of many lesions in different parts of the body. The lesions persisted despite the use of various antibiotics since a year. It has been recorded that his father has already been receiving anti-tuberculosis treatment. Osteomyelitis was detected in the distal part of right tibia by computerized tomography, and Mycobacterium tuberculosis was isolated from the specimens of skin lesion. The patient was immunocompetent, and there was no pulmonary involvement. Isoniazid (INAH), rifampin (RIF), ethambutol and morphozinamid therapy has been started and completed to 12 months with INAH and RIF. In the post-treatment follow-up of patient for one year, no relapse was detected. As a result, tuberculosis should be considered in patients with persistent skin lesions especially in endemic countries.

Characteristics of patients with Crimean-Congo hemorrhagic fever in a recent outbreak in Turkey and impact of oral ribavirin therapy.

We describe the epidemiological, clinical, and laboratory findings and the role of ribavirin therapy for 35 patients who received a diagnosis of Crimean-Congo hemorrhagic fever (CCHF). All patients had immunoglobulin M antibodies and/or PCR results positive for CCHF virus in blood or tissue specimens. Eighty-six percent of the patients were considered to have severe cases of CCHF. The overall case-fatality rate was 2.8%. Eight patients were given ribavirin, and all 8 survived. We suggest using ribavirin to treat patients with CCHF, particularly those with severe cases.

Risk of tuberculous infection among healthcare workers in a tertiary-care hospital in Ankara, Turkey.

OBJECTIVE: To determine risk factors for tuberculin skin test (TST) positivity among healthcare workers (HCWs). DESIGN: Two-step TST was performed in 2002. SETTING: Tertiary-care hospital in Ankara, Turkey. PARTICIPANTS: A sample of 491 hospital HCWs were included. Information related to demographics, profession, work duration, department, and individual and family history of tuberculosis (TB) was obtained by a structured questionnaire. RESULTS: Four hundred eight (83%) had two-step TST positivity. On multivariate analysis, male physicians (relative risk [RR], 1.5; 95% confidence interval [CI95], 1.23-1.69; P = .001), nurses (RR, 1.5; CI95, 1.29-1.66; P = .005), radiology technicians (RR, 1.7; CI95, 1.35-1.73; P = .002), laboratory technicians (RR, 1.6; CI95, 1.3-1.74; P = .007), and male housekeepers (RR, 1.6; (HCWs). CI95, 1.38-1.7; P < .001) had a higher risk than did female physicians. Among laboratory technicians, radiology technicians had the highest TST positivity (85%). HCWs working for less than 1 year (RR, 0.8; CI95, 0.72-0.98; P = .027) had a lower risk of infection. The HCWs having bacille Calmette-Guerin vaccination (RR, 1.12; CI95, 1.08-1.45) had higher TST positivity. CONCLUSION: Male physicians, nurses, and laboratory technicians had increased risk of Mycobacterium tuberculosis infection in this setting, but community exposure likely accounted for most infections.

In vitro antimicrobial susceptibility of Brucella species.

MIC50 and MIC90 values of doxycycline, rifampicin, ciprofloxacin, trimethoprim-sulphamethoxazole and ceftriaxone for 42 blood isolates of Brucella species were determined using the Etest. Thirty-seven isolates were identified as B. melitensis and five as B. abortus. Doxycycline had the lowest and rifampicin the highest MIC50 values. Four strains were non-susceptible to rifampicin, and one strain was resistant to trimethoprim-sulphamethoxazole. There is no significantly important resistance problem for antibiotics targeted against Brucella species in Turkey. However, since rifampicin is commonly used for prevalent diseases such as tuberculosis, the regional susceptibility pattern of rifampicin should be assessed periodically.

[A case report: Kikuchi-Fujimoto disease]. / Olgu raporu: Kikuchi-Fujimoto hastaligi.

Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis) which presents with fever and lymphadenopathy, should be considered in differential diagnosis of fever with unknown origin. We presented a 19 years old male patient with complaints of fever and lymphadenopathy. The case was diagnosed as Kikuchi-Fujimoto disease by histopathological evaluation.

Methicillin-resistant Staphylococcus aureus on hospital admission in Turkey.

A total of 900 patients were screened for methicillin-resistant Staphylococcus aureus (MRSA) on hospital admission, and 11 MRSA strains (1.2%) were detected. All 11 MRSA strains were positive for the mecA and PVL genes. Eight of the 11 MRSA-positive patients (72%) had a history of hospitalization within the previous 12 months.

Characteristics of cutaneous anthrax in Turkey.

BACKGROUND: Incidence of anthrax is diminishing in developed countries; however, it remains a public health problem in developing countries, especially those whose main source of income is farming. METHODOLOGY: Charts of patients hospitalized between 1992 and 2008 in the Infectious Diseases and Clinical Microbiology Department of Ankara Numune Education and Research Hospital were reviewed. RESULTS: Fifty-eight cases with cutaneous anthrax were reviewed. The mean age was 49.8, and 36.2% were female. The most common professions were farmers (62%), butchers (19%), and housewives (15%). The mean incubation period was eight days. Most cases (62%) were exposed to bacteria when butchering sick animals. Eighteen patients used an antibiotic before admission to hospital (31%). The predominantly affected sites were hands (39%) and fingers (29%), followed by forearms (12%), eyelids (7%) and necks (3%). All cases initially had painless ulcers with vesicles; dissemination of the lesion was seen in 27.5% of patients. Gram stain was positive in 11 cases; culture was positive in 7 cases for Bacillus anthracis. All patients except one were discharged and treated with penicillin and/or ciprofloxacin or imipenem. One patient with a disseminated lesion on the neck died even though a steroid was used with the antibiotic. CONCLUSIONS: Cutaneous anthrax should be considered as a possible diagnosis in cases with a painless ulcer with vesicles, edema, and a history of exposure to animals or animal products. Despite previous antibiotic use, taking smears and cultures should be encouraged. Treatment with penicillin G or penicillin procain alone is effective for cases with cutaneous anthrax without severe edema and superinfection.

Cognitive and emotional changes in neurobrucellosis.

OBJECTIVE: To determine cognitive and emotional changes among neurobrucellosis patients. METHODS: The patients with neurobrucellosis and controls with brucellosis without neurologic involvement were included in the study. Neurobrucellosis was diagnosed by the following criteria: (i) symptoms or clinical findings compatible with neurobrucellosis, including headache, confusion, mental and emotional changes; (ii) isolation of Brucella spp. from CSF and/or demonstration of antibodies to Brucella > or = 1/4 in the CSF; (iii) the presence of lymphocytosis, increased protein and decreased glucose levels in the CSF; and (iv) clinical improvement with appropriate treatment. Two psychiatrists interviewed the patients, and performed the Hamilton Depression Rating Scale (HDRS) tests and Mini-Mental State Examination (MMSE) tests. RESULTS: Thirty-four neurobrucellosis cases and 30 patients with brucellosis without neurological involvement were studied. The mean age was 41 years, 12 (41%) patients were female, 13 (46%) patients were farmers, and 7 (25%) patients were housewives. Among the neurobrucellosis cases, before the antibiotic therapy, the mean MMSE test score was 21.6, one week after the therapy 22.7, and two weeks after the therapy 24.3 (p=0.024, and p<0.001, respectively). At the day of admission before therapy, the mean of HDRS test was 9.9, one week after therapy it was 7.8, and two weeks after therapy it was 5 (p=0.014, and p<0.001, respectively). CONCLUSION: The cognitive and emotional disturbances among neurobrucellosis patients were documented by MMSE and HDRS tests. These disorders improve by antibiotic therapy, without any anti-depressive or anti-psychotic therapy.
