Mpox across countries from Central and Eastern Europe - 2022 outbreak.

BACKGROUND: The aim of the study was to assess socio-demographical characteristics, clinical presentation, and outcomes in patients diagnosed with mpox. METHODS: A survey on patients diagnosed with mpox was performed in 14 countries from Central and Eastern Europe. Data was compared according to HIV status and country of origin (EU vs. non-EU). Mpox diagnosis was confirmed by RT-PCR from oropharyngeal swabs, skin lesions, and other body fluids. RESULTS: Out of 154 patients confirmed with mpox in 2022, 99.3% were males, with a median age (years) of 35 (IQR 30-39), 90.2% MSM and 48.7% PLWH. Compared to HIV-negative subjects, PLWH had more frequent high-risk behaviours:chemsex (p = 0.015), group sex (p = 0.027), and a history of sexually transmitted infections (STIs) (p = 0.004). Persons from EU were more often PLWH (p = 0.042), MSM (p < 0.0001), had multiple sexual partners (p = 0.025), practiced chemsex (p = 0.008) or group-sex (p = 0.005) and had more often history of STIs (p < 0.0001). The median CD4 cell count/mL at mpox diagnosis was 713 (IQR 486-996) and 73.5% had undetectable HIV VL. The commonest clinical features were fever (108 cases), lymphadenopathy (78), and vesiculo-pustular rash: penile (76), perianal (48), limbs (67). Fifty-one (31%) persons were hospitalized due to complications or epidemiological reasons. Three patients received tecovirimat or cidofovir. The outcome was favorable for all patients, including 4 with severe forms. CONCLUSIONS: Mpox was diagnosed predominantly in young MSM, with high-risk behaviors and history of STIs. Effective contact tracing and vaccination are important strategic pillars to control mpox outbreaks.

Factors Influencing HIV Infection in Children Born to HIV-Infected Mothers in Turkey

Background: Human immunodeficiency virus (HIV) is still a challenge for children. About 15 to 45% of the HIV positive pregnant women can transmit the virus to their children during pregnancy, delivery and/or breastfeeding. The risk of transmission can be decreased my several measures. Aims: To identify factors associated with HIV infection in children born to HIV-infected mothers. Study Design: A multi-center retrospective cohort study. Methods: A ten-year retrospective cohort study in five dedicated HIV centers was conducted. The 325 women in our cohort were between the ages of 18 and 45. During the study period, 44 (13.5%) of these women gave birth and 51 babies were born. Of the 51 infants, 7 (13.7%) were HIV/AIDS positive. Results: Among the factors studied, breastfeeding, having a HIV-positive sibling and being on antiretroviral treatment during pregnancy and detectable HIV-RNA during delivery were found statistically significant. A multivariable logistic regression analysis showed that being on antiretroviral treatment during pregnancy is the most important predictor of mother-to-child transmission. Conclusion: Mother-to-child transmission appears to be an important route of HIV transmission in Turkey. Lack of antiretroviral treatment during pregnancy appears to be a key factor in transmission.

Fibrosis scores that can be used in follow-up of after direct-acting antiviral treatment: APRI, FIB-4, King score and GUCI.

INTRODUCTION: Sustained virologic response in the treatment of chronic hepatitis C can be achieved with direct-acting antivirals (DAA) in recent years. Monitoring virologic and histologic response to treatment is essential and noninvasive methods are preferred. In our study, we aimed to determine the regression of fibrosis following DAA treatment with serum fibrosis indices constituting a noninvasive method. METHOD: Patients with chronic hepatitis C to whom DAA treatment is started between January 2016 and January 2018 in our clinic are evaluated retrospectively. The fibrosis scores [fibrosis 4 index (FIB-4), aminotransferase platelet ratio (APRI), Fibro QKing score, age platelet index, Goteburg University Cirrhosis Index (GUCI), aspartate transaminase/alanine transaminase ratio (AAR)] are calculated with routine biochemical and hematologic tests of DAA-treated patients before treatment, at the end of treatment, and in the 12th and 24th weeks of treatment. In total, the course of seven scores calculated at four separate times including baseline was recorded and compared. RESULTS: In total 91 patients are included in the study. The average age was 51.16 ± 13.78 and 59.3% (n = 54) of patients were women. According to the baseline FIB-4 values, the patients were grouped as cirrhotic or noncirrhotic, and 11 of them were cirrhotic (12.1%). Statistically significant regression in APRI, FIB-4, GUCI and King scores is seen in all groups regardless of their cirrhotic status, treatment experience or genotype (P < 0.001). Specified scores had a positive, significant correlation with pretreatment biopsy results [area under curve (AUC): 0.800, 0.782, 0.749 and 0.746]. CONCLUSION: APRI, FIB-4, GUCI and King scores that have a positive correlation with biopsy can also be used for fibrosis recovery follow-up after treatment with DAAs.

Adherence to Treatment with Oral Nucleoside/Nucleotide Analogs in Patients with Chronic Hepatitis B.

Objectives: Adherence to antiviral treatment is important for treatment success and prevention of resistance. It was aimed to determine treatment adherence to nucleoside/nucleotide analogs and factors influencing on adherence. Methods: The study included 168 patients who received oral nucleoside/nucleotide analog with diagnosis of chronic hepatitis for at least 1 year. Data regarding demographic characteristics and missed drug were collected using a survey, while list of medication within prior year were extracted from pharmacy registry and Medication Possession Rate (MPR) was calculated. Results: There were 60 women (35.7%) and 108 men (64.3%) in the study. Mean age was calculated as 43.61±10.35 years. It was found that 29.2% of patients were non-adherent based on MPR (MPR<0.90). It was observed that adherence was improved on middle age. Treatment adherence was found to be higher in patients receiving medication due to disorders other than hepatitis B. It was found that there was no significant difference in adherence according to age, gender, occupation status, marital status, smoking or alcohol consumption habits, type of antiviral treatment, time and mode of drug intake, and biopsy finding at time of drug prescription. The most common cause was identified as forgetfulness for missed drug. Other common causes were inoccupation and alteration in daily routine. Conclusion: In our study, the treatment adherence determined by MPR was 70.8%. This rate was lower than those reported for chronic hepatitis B in the literature. It is important to monitor and encourage treatment adherence in patients with chronic hepatitis B by clinicians.

Cognitive Assessment of Young Adults Before and After Initiation of Combination Antiretroviral Therapy.

Objective: In the determination and monitoring of neurocognitive disorders in human immunodeficiency virus (HIV)-positive individuals, there is a need for significantly more practical methods which provide results in a shorter time than the tests that require challenging and specialized expertise. This study aimed to evaluate cognitive functions and the factors affecting them in naïve HIV-positive patients using by Montreal Cognitive Assessment (MoCA) test before and after the initiation of combination antiretroviral therapy. Materials and Methods: HIV-positive, treatment-naïve patients monitored between January-June 2017 were included in the study. The MoCA test was performed at the beginning and the sixth month of the treatment. Results: Forty male patients were included in the study. The mean age was calculated as 29.1±4.0. When the factors affecting the MoCA score were examined, there was a significant relationship between the education level and the MoCA score. Smoking, using alcohol, and substance did not have a significant impact on baseline MoCA values. A significant correlation was found between cluster differentiation 4 (CD4) count and HIV RNA level and attention function. There was a significant increase in the total MoCA score and the MoCA subgroup scores at the end of the sixth month of the treatment. Conclusion: MoCA test is one of the most practical tests that can be applied in a short time period, and it was found useful in evaluating the changes in the cognitive functions of HIV-positive patients during antiretroviral treatment.

Prevalence and mortality of cancer among people living with HIV and AIDS patients: a large cohort study in Turkey.

BACKGROUND: Cancer is responsible for elevated human immunodeficiency virus (HIV)-related mortality but there are insufficient data about cancer in HIV-positive patients in Turkey. AIMS: We aimed to investigate the prevalence and mortality of cancer among people living with HIVand AIDS patients in Istanbul, Turkey. METHODS: Between January 1998 and December 2016, people living with HIVand AIDS patients were enrolled in this study by the ACTHIV-IST Study Group, which consists of 5 centres to follow-up HIV-positive patients in Istanbul. The cancer diagnoses included AIDS-defining cancers (ADCs) and non AIDS-defining cancers (NADCs). RESULTS: Among 1872 patients, 37 (1.9%) were diagnosed with concurrent cancer. Eleven patients were diagnosed during follow-up; the prevalence of cancer among people living with HIVand AIDS patients was 2.6%. Among 48 cancer patients, 35 patients had ADCs, and 32 of them were diagnosed at their first hospital admission. There were 1007 late presenters and 39 of them had cancer (29 were ADCs). The most prevalent NADCs were gastrointestinal, genitourinary, and pulmonary cancers. NADCs were mostly diagnosed during follow-up of patients. The mortality of this group was significantly higher than that of patients with ADCs (53.9% vs 22.9%). CONCLUSIONS: These results indicate the importance of cancer screening at diagnosis and during follow-up of HIV infection. A detailed physical examination contributes to diagnosis of the most prevalent ADCs (Kaposi's sarcoma and non-Hodgkin's lymphoma), especially in late presenters. For NADCs, individual risk factors should be considered.

Serum soluble urokinase-type plasminogen activator receptor and interferon-γ-induced protein 10 levels correlate with significant fibrosis in chronic hepatitis B.

BACKGROUND: Hepatitis B virus (HBV) presents an important public health problem. Liver biopsy is currently the gold standard for assessing the degree of intrahepatic inflammation and for staging liver fibrosis. However, the value of liver biopsies is limited by sampling errors, understaging and interobserver variability in interpretation. There is, therefore, a need to identify novel, non-invasive serologic biomarkers for the development of new predictive models of fibrosis. METHODS: We enrolled patients with chronic hepatitis B infection (CHB) and examined the relationships between serum soluble urokinase plasminogen activator receptor (suPAR) and interferon-induced protein-10 (IP-10), and the results of liver biopsies. Healthy volunteers with normal aminotransferase levels and negative serological results for HBV, hepatitis C virus and human immunodeficiency virus were recruited as controls. RESULTS: Mean platelet volume, serum suPAR and IP-10 were significantly elevated in patients with CHB compared with controls. Median serum suPAR and IP-10 levels were significantly higher in patients with liver fibrosis compared with patients with mild fibrosis. There was no significant difference in mean platelet volume or aspartate aminotransferase-to-platelet ratio index scores between patients with mild and significant fibrosis. CONCLUSION: suPAR and IP-10 were able to distinguish between significant and mild fibrosis with good sensitivity and specificity, and may thus represent useful biomarkers for identifying patients with significant fibrosis.
