Do elevated thyrotropin levels increase the risk of miscarriages: yes or no?

BACKGROUND: To examine correlation between elevated levels of thyrotropin with the frequency of miscarriages. METHODS: A cross-sectional study was conducted on the 380 respondents and it investigated TSH (thyrotropin), thyroid peroxidase antibody(anti-TPO) and free thyroxine (FT4) in pregnant women who had a miscarriage (N = 179) and pregnant women with normal pregnancies (N = 201). RESULTS: The incidence of subclinical hypothyroidism in the miscarriages group was higher than in control group (61.4% vrs 15.79% (p < 0.001). In the miscarriages group with hypothyroidism (first trimester) mean value of TSH was significantly higher 4.31 ± 2.55 mIU/L compared to the control group 1.95 ± 0.86mIU/L (p < 0.001). Logistic multivariate regression revealed that TSH and body mass index (BMI) have a significant influence on the miscarriage; TSH level has a higher odds ratio (OR) 1.47 CI (95% 1.22-1.78) than BMI (OR) 1.14 CI (95% 1.06-1.23)) (p < 0.001). The combination of thyroid autoimmunity and TSH > 2.5mIU/L increase the risk of miscarriage (65.75%) compared to positive anti-TPO antibodies and TSH < 2.5mIU/L(14.15%)(p < 0.001). CONCLUSIONS: Higher TSH levels correspond with obesity during early pregnancy and may be a sign of maternal thyroid dysfunction. Physiological thyroid function in the first trimester of pregnancy is important for perinatal outcome.

Classical fever of unknown origin in 21 countries with different economic development: an international ID-IRI study.

Fever of unknown origin (FUO) is a serious challenge for physicians. The aim of the present study was to consider epidemiology and dynamics of FUO in countries with different economic development. The data of FUO patients hospitalized/followed between 1st July 2016 and 1st July 2021 were collected retrospectively and submitted from referral centers in 21 countries through ID-IRI clinical research platform. The countries were categorized into developing (low-income (LI) and lower middle-income (LMI) economies) and developed countries (upper middle-income (UMI) and high-income (HI) economies). This research included 788 patients. FUO diagnoses were as follows: infections (51.6%; n = 407), neoplasms (11.4%, n = 90), collagen vascular disorders (9.3%, n = 73), undiagnosed (20.1%, n = 158), miscellaneous diseases (7.7%, n = 60). The most common infections were tuberculosis (n = 45, 5.7%), brucellosis (n = 39, 4.9%), rickettsiosis (n = 23, 2.9%), HIV infection (n = 20, 2.5%), and typhoid fever (n = 13, 1.6%). Cardiovascular infections (n = 56, 7.1%) were the most common infectious syndromes. Only collagen vascular disorders were reported significantly more from developed countries (RR = 2.00, 95% CI: 1.19-3.38). FUO had similar characteristics in LI/LMI and UMI/HI countries including the portion of undiagnosed cases (OR, 95% CI; 0.87 (0.65-1.15)), death attributed to FUO (RR = 0.87, 95% CI: 0.65-1.15, p-value = 0.3355), and the mean duration until diagnosis (p = 0.9663). Various aspects of FUO cannot be determined by the economic development solely. Other development indices can be considered in future analyses. Physicians in different countries should be equally prepared for FUO patients.

Profiles of multidrug-resistant organisms among patients with bacteremia in intensive care units: an international ID-IRI survey.

Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were Klebsiella pneumoniae, and 55.3% of XDR were Acinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025-15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462-3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189-5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076-2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.

A novel id-iri score: development and internal validation of the multivariable community acquired sepsis clinical risk prediction model.

We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. In this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. The median age was 68 (51-77) years, and 174 (46,6%) of the patients were females. The median hospitalization time of the patients was 15 (10-21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). The possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). The system has yielded successful results in terms of predicting mortality in CA sepsis patients.

Attitudes of dental practitioners towards antimicrobial therapy in Croatia and Bosnia and Herzegovina.

INTRODUCTION: The objective of this study was to assess perceptions and attitudes amongst dental practitioners in relation to antibiotic usage and antibiotic resistance. METHODS: Self-administered questionnaire was given to dental practitioners employed in south Croatia, west Herzegovina and Sarajevo, Bosnia and Herzegovina (N = 115). RESULTS: 81.7% of respondents agreed the usage of antimicrobials is frequently uncritical and unnecessary. 83.5% of dental practitioners reported that they have used guidelines in their practice; however, only 9 out of 115 stated valid guidelines. One-third of the respondents agreed or were undecided that the usage of antimicrobials in every oral inflammatory process treatment is justified. Furthermore, 13% was undecided and 26% agreed that pregnant women and breastfeeding women should not use any antimicrobials. However, three quarters of respondents considered they had satisfactory knowledge on antimicrobials. DISCUSSION: The respondents considered they had satisfactory knowledge on antimicrobials, which was in contrast to the knowledge shown, but also expressed the need for additional education. Therefore, adequate measures include the creation of the local guidelines, their implementation, and updating the practitioners' knowledge on antibiotic use and resistance through continuous educational courses.

Depression Disorders in Patients with Chronic Hepatitis C.

BACKGROUND: Chronic hepatitis C was until recently treated with a combined therapy of interferon and ribavirin. More recently, direct antiviral agents (DAA), are being introduced. They are more tolerable and have fewer side effects, with better treatment results. In the Federation of Bosnia and Herzegovina we have started using this new therapy, with a limited financial opportunity. Large numbers of patients with chronic hepatitis C are former or current addicts, some of them treat their addiction with methadone or buprenorphine. These patients often formerly have a depression disorder and during treatment of chronic hepatitis need supervision of a psychiatrist, due to one of the side effects of interferon being deterioration of depression. Using this research we wanted to valorize the depression disorder of our patients, to indicate the effects of interferon on depression deterioration and the need for a new therapy protocol. SUBJECTS AND METHODS: Examinees were patients with chronic hepatitis C on interferon therapy, which we divided into three groups: those who were never addicts, then the group of patients who were earlier addicts and have a long abstinence and patients who treat their addiction with a replacement therapy of methadone or buprenorphine. All patients completed Beck's test, which determines the level of depression, before and after interferon therapy. RESULTS: Patients who used to be addicts or were on replacement therapy had mild or moderate depression before interferon treatment in a large number. After interferon therapy, there was a statistically substantial increase of patients with serious depression, which was not noted before the therapy. CONCLUSION: Interferon therapy deteriorates depression in patients with chronic hepatitis C and there should be a strive for new therapies with less side effects in treatment. No patients stopped therapy. That is a result of community work and supervision over patients from both hepatologists and psychiatrists.

PANDEMIC INFLUENZA A (H1N1) 2009 PRESENTING AS A MILD DISEASE IN CHILDREN IN A CROATIAN CLINICAL CENTRE.

Pandemic influenza A virus (H1N1) 2009 causes a disease that is epidemiologically and clinically not significantly different from seasonal influenza, but there are differences. The aim of the study was to display and compare epidemiological and clinical characteristics of pandemic influenza in children. At Dr. Fran Mihaljevic University Hospital for Infectious Diseases in Zagreb, in the first two seasons, the incidence of pandemic influenza virus A (H1N1) in particular was exhaustively analyzed only in patients with laboratory-confirmed pandemic influenza A virus (H1N1) 2009. In hospitalized children with documented influenza pandemic, moderate form of the disease predominated, which ultimately meant shorter hospital stay and fewer complications. Otitis media was the rarest complication in children in both seasons. In conclusion, children younger than 5 years, especially boys, were vulnerable groups for pandemic influenza, presenting as a mild disease with low mortality and few complications. Most of the affected children with influenza did not have important risk factors such as asthma and obesity, highlighted by other authors as significant risk factors.

Socioeconomics Conditionality of Seroprevalence of Hepatitis a in Three South-West Cantons of the Federation of Bosnia and Herzegovina.

The prospective study, which was made from Jan 1st 2009. till Dec 31st 2010. in the Clinic for Infectious Diseases within Clinical Hospital Mostar has been implemented in the areas of three southwestern cantons of the Federation of Bosnia and Herzegovina. We wanted to define the seroprevalence of the researched area using seroepidemiological testing of different groups of the population, based on the distribution by sex, age, education, residence and watersupply. The aim of this research was to prove the hypothesis that the decrease of seroprevalency of Hepatitis A has been directly related to the improvement of socio-economic conditions of life that at the end brought the decrease of the total prevalence in patients in younger age groups. The total of 420 examinees from the reasserted sample were analysed and they were classify into age groups. The first group was for the children up to 10 years. Then the group 11-20 follows and etc up to the last group, that complies examinees older than 60. In this way we have got seven groups of 60 examinees, from which the half of them was urban, and the other half was rural inhabitants. In every group analysed the half of examinees were females and the other half were males. The results we acquired with this research did not show any statistically relevant differences of seroprevalence of Hepatitits A between the urban and rural areas, between the sexes, nor between the populations which used different wattersupply objects. A statistically relevant difference was found between populations of different levels of education, but the most important difference was found between seroprevalency in different age groups. Seroprevalence in younger age groups was substantially low and increased in groups rising with age. Comparing this data to results from other similair researches from developed and undeveloped countries we concluded that the researched area, by the level of seroprevalency of Hepatitis A belongs to the category of developed countries.

Neurological Manifestation in Hospitalized Patients With Acute SARS-CoV-2 Infection.

OBJECTIVE: The main objective of this research is to determine the prevalence and characteristics of neurological manifestations in hospitalized patients with SARS-CoV-2 infection. METHODS: A cross-sectional study was conducted. 572 hospitalized patients at the COVID Department of Pulmonology of the Mostar University Clinical Hospital in the six-month period from October 31, 2020, to April 30, 2021, were included. We analyzed the incidence of neurological manifestations and the influence of comorbidities and metabolic syndrome on stroke incidence in COVID-19 patients. We analyzed hospital length of stay and mortality in patients with and without neurological manifestations. The research was conducted with respect to all the determinants of the Helsinki Declaration. RESULTS: 572 patients, 351 men (61.4%), and 221 women (38.6%) were included. A fatal outcome was present in a quarter of patients (25.3%). Neurological manifestations were found in 163 patients (28.5%). Myalgia was the most common (16.1%). The following were reported: headache (9.6%), loss of taste (7.34%), loss of smell (6.8%), and vertigo (2.5%). There was a significant difference regarding loss of smell between males and females (p=0.04). The cerebrovascular incident was present in 2.97% of patients and was more frequent in the group of patients with metabolic syndrome. Patients with neurological manifestations had a longer hospital stay, but it was not statistically significant (p=0.9319). The presence of neurological manifestations in general did not influence the mortality rate. CONCLUSION: Patients with SARS-CoV-2 infection can present with neurologic findings such as myalgia, headache, loss of smell or taste, vertigo, as well as cerebrovascular incidents. Patients with neurological manifestations had longer hospital stays, but the presence of neurological manifestations in general did not influence the mortality rate.

Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey.

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (~5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

The occurrence of hemorrhagic fever with renal syndrome in southern parts of Bosnia and Herzegovina.

Bosnia and Herzegovina (B&H) has been known as an endemic region for hemorrhagic fever with renal syndrome (HFRS) for over 50 years. Multiple epidemics of this disease have been registered so far, especially in endemic parts of Central and Northeastern Bosnia, as well as the Sarajevo region. Seroepidemiological investigations demonstrate naturalization of Hantaviruses and their wide spread in B&H. However, there are no studies from the southern areas of B&H, and endemic foci of this disease are unknown. The aim of this study was to determine the distribution and serologic prevalence of Hantavirus infections by testing for specific IgG antibodies against hantaviruses in the population of Herzegovina. This study included two groups of participants. The target group consisted of 300 participants from exposed professional and population groups, and control group included 100 educators with lower exposure to HFRS. Identification of specific IgG antibodies against hantaviruses in 16 participants confirmed an initial assumption about the presence of Hantavirus infections in the region of interest. Seroprevalence of 5% was registered in the "exposed" and 1% in the "unexposed" group. Simultaneous circulation of Puumala (PUU) and Dobrava (DOB) viruses was discovered. The frequency of positive antibody results was higher in the population above 50 years of age, and three times more prevalent in men then at women. The highest proportion of exposed participants (80%) was registered in the municipalities which geographically belong to high or mountainous Herzegovina.

HBV and HCV serological monitoring among injection drugs users in opiate substitution treatment in Bosnia and Herzegovina.

INTRODUCTION: Use of intravenous heroin carries a risk of serious medical conditions, including acquiring blood-borne infections. Therefore, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection represent a threat for people who inject drugs (PWID). The objectives of this study were to determine the extent and characteristics of risk factors for acquiring HBV and HCV infection in PWID included in opiate substitution treatment in the southern part of Bosnia and Herzegovina (B&H). METHODOLOGY: The study included 120 adult PWID of both sexes who participated in opiate substitution treatment. All participants were interviewed, and their blood samples were tested for the presence of the surface hepatitis B virus antigen (HBsAg) and hepatitis C virus antibodies (anti-HCV). Prevalence data were obtained and compared to the serological status. RESULTS: HBsAg prevalence among PWID was 0.8% (1/120), whereas seroprevalence of anti-HCV was 52.5% (63/120). PWID exposed to risk-behavior factors (such as unsafe sexual activity, serving prison sentence, and tattooing) were more frequently anti-HCV positive. Sharing drug paraphernalia was found to be the most significant risk factor. The highest predictive values for acquiring HCV-infection were attributed to PWID who used heroin for more than three years and who were unmarried. CONCLUSIONS: HBsAg prevalence among PWID is rare (0.8%), while HCV-infection (52.5%) presents an important health and social issue among PWID in B&H. Sharing drug paraphernalia and intravenous heroin use longer than three years were the most prominent risk-behavior factors among the patients we investigated.

Different features of influenza A H1N1pdm09 virus infection among adults in 2009/10 and 2010/11.

INTRODUCTION: Influenza A H1N1pdm09 virus infection causes an epidemiologically and clinically severe disease mostly characterized by pneumonia, resulting in a high mortality rate. The purpose of this study was to investigate and compare epidemiological and clinical characteristics of influenza A H1N1pdm09 virus infection in patients hospitalized during the pandemic (2009/10) and post-pandemic seasons (2010/11). METHODOLOGY: The data of patients with laboratory-confirmed influenza A H1N1pdm09 virus infection hospitalized and treated at the University Hospital for Infectious Diseases Dr. Fran Mihaljevic in Zagreb, Croatia in the first two seasons of appearance were analyzed. RESULTS: Compared to the pandemic season, in the post-pandemic season, patients were hospitalized longer, had higher values of inflammatory parameters, and were more often treated with antibiotics. The total number of risk factors in patients did not vary significantly between the two seasons. In the pandemic season, a significantly higher number of obese patients and patients with chronic lung disease was observed, whereas in the post-pandemic season, a statistically significant number of patients presented with symptoms of chronic cardiac and neuromuscular diseases. Primary viral pneumonia was frequently registered in younger adults during the pandemic season, whereas in the post-pandemic season, there were more cases of bacterial pneumonia. CONCLUSIONS: During the pandemic season, the influenza A H1N1pdm09 virus infection caused a severe disease with rare bacterial complications, especially in adult patients. The common characteristics of the influenza A H1N1pdm09 virus were lost in the post-pandemic season, assuming the shape and characteristics of the seasonal influenza A virus.

Brucellosis in children in Bosnia and Herzegovina in the period 2000 - 2013.

AIM: To analyse clinical, laboratory and epidemiological characteristics of brucellosis in children in Bosnia and Herzegovina. METHODS: The study included 246 children aged 0-18 years, who were hospitalized in Clinics and Departments for Infectious Diseases in Tuzla, Sarajevo, Banja Luka, Zenica and Bihac in the period 2000-2013, in whom the diagnosis of brucellosis was established based on anamnestic data, clinical features and positive results from blood culture and/or positive results from one of the serological tests. RESULTS: In this period, a total of 2630 patients, 246 (9.35%) of whom were children, were treated from brucellosis at the Clinics and Departments in Bosnia and Herzegovina. In the majority of cases, the children were from rural parts of the country, 226 (91.87%);214 (87.04%) cases had direct contact with sick animals, sick family member or consumption of unpasteurized dairy products from farms where brucellosis had been already established. Male children predominated, 157 (63.82%). The most frequent clinical features in affected children were fever, 194 (78.86%) and joint pain, 158 (64.22%). The average duration of antimicrobial treatment was 42.85 ± 10.67 days. A total of 228 (92.68%) children were completely cured, while relapses occurred in 18 (7.32%) children. CONCLUSION: Since brucellosis is an endemic disease in Bosnia and Herzegovina, it is important that physicians in their daily practice consider brucellosis and establish proper diagnosis and therapy in children with prolonged fever, arthralgia, leukopenia and positive epidemiological data, especially in rural parts of the country.

The first evidence of lyme neuroborreliosis in southern bosnia and herzegovina.

Lyme borreliosis (LB) is caused by the spirochete Borrelia burgdorferi, which is transmitted to humans by ticks of the Ixodes ricinus complex. It is manifested by a variety of clinical symptoms and affects skin, joints, heart, and nervous system. Neurological manifestations are predictable and usually include meningoencephalitis, facial palsy, or radiculopathy. Recently, a dramatic rise in the number of diagnosed cases of LB has been observed on the global level. Here we show the first case of Lyme neuroborreliosis in southern Bosnia and Herzegovina, which was first presented by erythema chronicum migrans. Unfortunately, it was not recognized or well treated at the primary care medicine. After eight weeks, the patient experienced headache, right facial palsy, and lumbar radiculopathy. After the clinical examination, the neurologist suspected meningoencephalitis and the patient was directed to the Clinic for Infectious Disease of the University Hospital Mostar, where he was admitted. The successful antimicrobial treatment with the 21-day course of ceftriaxone was followed by normalization of neurological status, and then he was discharged from the hospital. This case report represents an alert to all physicians to be aware that LB is present in all parts of Bosnia and Herzegovina, as well as in the neighboring regions.

Surveillance, control and management of infections in intensive care units in Southern Europe, Turkey and Iran--a prospective multicenter point prevalence study.

OBJECTIVE: We aimed to compare the features of intensive care units (ICUs), their antimicrobial resistance patterns, infection control policies, and distribution of infectious diseases from central Europe to Mid-West Asia. METHODS: A cross-sectional point prevalence study was performed in 88 ICUs from 12 countries. Characteristics of ICUs, patient and antibiotic therapy data were collected with a standard form by infectious diseases specialists. RESULTS: Out of 749, 305 patients at least with one infectious disease were assessed and 254 patients were reported to have coexistent medical problems. When primary infectious diseases diagnoses of the patients were evaluated, 69 had community-acquired, 61 had healthcare-associated, and 176 had hospital-acquired infections. Pneumonia was the most frequent ICU infection seen in half of the patients. Distribution of frequent pathogens was as follows: Enteric Gram-negatives (n = 62, 28.8%), Acinetobacter spp. (n = 47, 21.9%), Pseudomonas aeruginosa (n = 29, 13.5%). Multidrug resistance profiles of the infecting microorganisms seem to have a uniform pattern throughout Southern Europe and Turkey. On the other hand, active and device-associated infection surveillance was performed in Turkey more than Iran and Southeastern Europe (p < 0.05). However, designing antibiotic treatment according to culture results was highest in Southeastern Europe (p < 0.05). The most frequently used antibiotics were carbapenems (n = 92, 30.2%), followed by anti-gram positive agents (vancomycin, teicoplanin, linezolid, daptomycin, and tigecycline; n = 79, 25.9%), beta-lactam/beta lactamase inhibitors (n = 78, 25.6%), and extended-spectrum cephalosporins (n = 73, 23.9%). CONCLUSION: ICU features appears to have similar characteristics from the infectious diseases perspective, although variability seems to exist in this large geographical area.
