RESUMEN
BACKGROUND: In the Balkans, rising concerns about invasive fungal infections over the past decade stem from various factors. Primarily, there has been a notable uptick in immunocompromised individuals, including those with chronic illnesses like immunological and hematological diseases. Thus, it is essential to assess the region's laboratory capabilities and the availability of antifungals. This evaluation is vital for gauging the preparedness to diagnose and treat fungal infections effectively, thus minimizing their public health impact. METHODS: Data were collected via an online questionnaire targeting healthcare professionals specializing in relevant fields across diverse healthcare settings in Balkan countries. The survey covered various aspects, including diagnostic methods, imaging techniques, and available antifungal armamentarium. RESULTS: Responses were obtained from 50 institutions across the Balkans. While conventional diagnostic methods like microscopy (96 %) and culture (100 %) diagnostics were widely available, access to newer diagnostic tools such as molecular assays (61 %) were limited, often relying on outsourced services. Imaging modalities like ultrasound (100 %) and CT scans (93 %) were universally accessible. A variety of antifungal drugs were available, including amphotericin B formulations (80 %), echinocandins (79 %), and triazoles (100 %). However, access to newer agents like posaconazole (62 %) and isavuconazole (45 %) was inconsistent. Therapeutic drug monitoring (53 %) services were also limited. CONCLUSION: The study underscores the need for equitable access to diagnostic facilities and antifungal treatments across healthcare settings in the Balkan geographic region. Improving access to molecular diagnostic tools and essential antifungal drugs, as well as implementing therapeutic drug monitoring, would optimize the management of fungal infections in the region.

Background: Treatment of Philadelphia chromosome negative myeloproliferative neoplasms (Ph - MPNs) requires individualized approach depending on multiple factors. Novel pegylated Interferon (IFN) formulations have become an attractive therapeutic option in young Ph- MPN patients associated with better patient compliance. Methods: In this retrospective observational study a total of 16 high-risk Ph- MPN patients treated off-label with ropeginterferon alfa-2b given twice monthly, were included. Median follow-up was 24 months. High-risk patients were defined using the IPSET score. Response to treatment was evaluated using ELN, IWG-MET EUMNET standardized criteria and occurrence of side effects was documented. Results: 11 patients were female (68.8%) and 5 male (31.2%); average age at diagnosis was 36 years (17-51); 12 patients (75%) had ET, one (6.2%) PV and three (18.8%) hypercellular phase of PMF. JAK2V617F mutation was detected in 10 patients (62.5%), CALR in three (18.8%), and three (18.7%) were triple-negative cases. In 7 patients (43.7%), ropeginterferon alfa-2b was used in first-line, and 9 (56.3%) were previously treated with HU and/or standard IFN. Among initially ropeginterferon alfa-2b treated patients, complete haematological response was observed in 4/7 (57.1%), partial in 2/7 (28.6%) and suboptimal in one (14.3%). Complete haematological response was observed in 8/9 (88.9%) among previously treated patients. Average time to blood count normalization was 8 weeks, at a dose ranging between 100mcg and 300mcg. Side effects were observed in one patient (6.2%). Conclusion: Our experience is in support of previous studies regarding ropeginterferon alfa-2b efficacy and safety profile in the treatment of young patients with Ph- MPNs.

Background: Nirmatrelvir/ritonavir treatment decreases the hospitalisation rate in immunocompetent patients with COVID-19, but data on efficacy in patients with haematological malignancy are scarce. Here, we describe the outcome of nirmatrelvir/ritonavir treatment in a large cohort of the latter patients. Methods: This is a retrospective cohort study from the multicentre EPICOVIDEHA registry (NCT04733729) on patients with haematological malignancy, who were diagnosed with COVID-19 between January and September 2022. Patients receiving nirmatrelvir/ritonavir were compared to those who did not. A logistic regression was run to determine factors associated with nirmatrelvir/ritonavir administration in our sample. Mortality between treatment groups was assessed with Kaplan-Meier survival plots after matching all the patients with a propensity score. Additionally, a Cox regression was modelled to detect factors associated with mortality in patients receiving nirmatrelvir/ritonavir. Findings: A total of 1859 patients were analysed, 117 (6%) were treated with nirmatrelvir/ritonavir, 1742 (94%) were treated otherwise. Of 117 patients receiving nirmatrelvir/ritonavir, 80% had received ≥1 anti-SARS-CoV-2 vaccine dose before COVID-19 onset, 13% of which received a 2nd vaccine booster. 5% were admitted to ICU. Nirmatrelvir/ritonavir treatment was associated with the presence of extrapulmonary symptoms at COVID-19 onset, for example anosmia, fever, rhinitis, or sinusitis (aOR 2.509, 95%CI 1.448-4.347) and 2nd vaccine booster (aOR 3.624, 95%CI 1.619-8.109). Chronic pulmonary disease (aOR 0.261, 95%CI 0.093-0.732) and obesity (aOR 0.105, 95%CI 0.014-0.776) were not associated with nirmatrelvir/ritonavir use. After propensity score matching, day-30 mortality rate in patients treated with nirmatrelvir/ritonavir was 2%, significantly lower than in patients with SARS-CoV-2 directed treatment other than nirmatrelvir/ritonavir (11%, p = 0.036). No factor was observed explaining the mortality difference in patients after nirmatrelvir/ritonavir administration. Interpretation: Haematological malignancy patients were more likely to receive nirmatrelvir/ritonavir when reporting extrapulmonary symptoms or 2nd vaccine booster at COVID-19 onset, as opposed to chronic pulmonary disease and obesity. The mortality rate in patients treated with nirmatrelvir/ritonavir was lower than in patients with targeted drugs other than nirmatrelvir/ritonavir.

RESUMEN
Patients with lymphoproliferative diseases (LPD) are vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Here, we describe and analyze the outcome of 366 adult patients with chronic lymphocytic leukemia (CLL) or non-Hodgkin Lymphoma (NHL) treated with targeted drugs and laboratory-confirmed COVID-19 diagnosed between February 2020 and January 2022. Median follow-up was 70.5 days (IQR 0-609). Most used targeted drugs were Bruton-kinase inhibitors (BKIs) (N= 201, 55%), anti-CD20 other than rituximab (N=61, 16%), BCL2 inhibitors (N=33, 9%) and lenalidomide (N=28, 8%).Only 16.2% of the patients were vaccinated with 2 or more doses of vaccine at the onset of COVID-19. Mortality was 24% (89/366) on day 30 and 36%(134/366) on the last day of follow-up. Age >75 years (p<0.001, HR 1.036), active malignancy (p<0.001, HR 2.215), severe COVID-19 (p=0.017, HR 2.270) and admission to ICU (p<0.001, HR 5.751) were risk factors for mortality at last day of follow up. There was no difference in OS rates in NHL vs CLL patients (p=0.306), nor in patients treated with or without BKIs (p=0.151). Mortality in ICU was 66% (CLL 61%, NHL 76%). Overall mortality rate decreased according to vaccination status, being 39% in unvaccinated patients, 32% and 26% in those having received one or two doses, respectively, and 20% in patients with a booster dose (p=0.245). Overall mortality rate dropped from 41% during the first semester of 2020 to 25% at the last semester of 2021. These results show increased severity and mortality from COVID-19 in LPDs patients treated with targeted drugs.
RESUMEN
Limited data are available on breakthrough COVID-19 in patients with hematologic malignancy (HM) after anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. Adult patients with HM, ≥1 dose of anti-SARS-CoV-2 vaccine, and breakthrough COVID-19 between January 2021 and March 2022 were analyzed. A total of 1548 cases were included, mainly lymphoid malignancies (1181 cases, 76%). After viral sequencing in 753 cases (49%), the Omicron variant was prevalent (517, 68.7%). Most of the patients received ≤2 vaccine doses before COVID-19 (1419, 91%), mostly mRNA-based (1377, 89%). Overall, 906 patients (59%) received COVID-19-specific treatment. After 30-day follow-up from COVID-19 diagnosis, 143 patients (9%) died. The mortality rate in patients with the Omicron variant was 7.9%, comparable to other variants, with a significantly lower 30-day mortality rate than in the prevaccine era (31%). In the univariable analysis, older age (P < .001), active HM (P < .001), and severe and critical COVID-19 (P = .007 and P < .001, respectively) were associated with mortality. Conversely, patients receiving monoclonal antibodies, even for severe or critical COVID-19, had a lower mortality rate (P < .001). In the multivariable model, older age, active disease, critical COVID-19, and 2-3 comorbidities were correlated with a higher mortality, whereas monoclonal antibody administration, alone (P < .001) or combined with antivirals (P = .009), was protective. Although mortality is significantly lower than in the prevaccination era, breakthrough COVID-19 in HM is still associated with considerable mortality. Death rate was lower in patients who received monoclonal antibodies, alone or in combination with antivirals.

The majority of Gaucher Disease (GD) cases result from pathologic mutations in the GBA1 gene. A rich mutational spectrum of about 500 identified variants has been recognized. The disease is characterized by phenotypic diversity. Data regarding the genotype-phenotype correlation are scanty and inconclusive. Here, we summarize the genetic and phenotypic "portraits" of 14 patients with GD type 1 in the Republic of North Macedonia, 4 of Macedonian and 10 of Albanian origin. Altogether, 6 variants were detected, compounding 6 different genotypes. All genotypes contained the N370S variant, which was detected with an overall prevalence of 60.7%. Other frequent variants included the 1263del55 deletion and the double mutant allele D409H;H255Q, each with a prevalence of 14.2%. We detected two rare mutations: W92* - a pathogenic nonsense mutation and D399N - a single nucleotide variant of uncertain pathogenicity. The most common genotypes were N370S/1263del55 and H255Q;D409H/N370S, both present in 4/14 patients, followed by N370S homozygosity (3/14). Splenomegaly was the most common clinical manifestation, identified in all patients. Hepatomegaly was less frequent and was present in 50% of cases. Thrombocytopenia was present in 9/14, while half of the patients had anemia. Bone pathology was demonstrated in 8 patients. Patients with different genotypes displayed a high degree of phenotypic heterogeneity, suggesting that the other allele determines the onset and severity of the disease in patients with the N370S mutation. Longer follow-up, bigger cohorts of patients and multicentric studies should be conducted to further define the association between the genotypic and phenotypic expression in GD.
RESUMEN
Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a preventable cause of in-hospital death, and one of the most prevalent vascular diseases. There is a lack of knowledge with regards to contemporary presentation, management, and outcomes of patients with VTE. Many clinically important subgroups (including the elderly, those with recent bleeding, renal insufficiency, disseminated malignancy or pregnant patients) have been under-represented in randomized clinical trials. We still need information from real life data (as example RIETE). The paper presents case series with VTE in special conditions, including cancer associated thrombosis, malignant homeopathies, as well in high risk population.

BACKGROUND: Erdheim Chester disease (ECD) is a rare form of non-Langerhans histiocytosis that still presents a diagnostic and clinical dilemma. CASE PRESENTATION: We present a rare case of ECD, young 31 male with atypical localisation and soft tissue presentation and no bone involvement. He started clinical investigations due to subcutaneous tumour mass in the lumbar spine that caused severe back pain. Skin biopsy revealed ECD with Immunohistochemistry CD68+, CD10+, CD11c+, vimentin+, S100A4+. Activating BRAFV600E mutation was positive from the tumour tissue. The patient was referred to the haematology department. PET CT was performed for initial disease staging. Treatment was started with corticosteroids (methylprednisolone 0.5 mg/kg per day), and after 7 days, a significant clinical improvement was noticed in terms of pain disappearance with no need for pain killers. After two weeks, treatment with interferon Alfa (IFN-α) was started in a dose of 3 million units 3 times per week. After 4 months of interim treatment PET, CT revealed a significant reduction of the tumour mass. Therapy with IFN-α was continued, and the patient is still clinically in good condition. CONCLUSION: It can be concluded that shortening the time of diagnosis of ECD is essential in treatment outcome of this disease. Still, large studies have to confirm the best treatment of this rare condition.
RESUMEN
Posterior reversible encephalopathy syndrome (PRES) is one of the most serious complication after allogeneic stem cell transplantation in paediatric setting. It is most commonly reported as adverse event of immunosuppressive strategies during transplantation. We present a case of a 7 years old girl with myelodysplastic syndrome (MDS) treated with allogeneic stem cell transplantation (ASCT) at our department. Diagnosis of PRES was confirmed by imaging techniques during the first month after transplant and it was very likely connected with cyclosporine neurotoxicity. The aim of this article is to present our first experience in diagnosing and treating PRES in paediatric stem cell transplantation. Our experience showed that PRES is one of the reasons for higher transplant related mortality in children. Early prediction of factors contributing to PRES and closely monitoring of patient's vital signs, especially blood pressure, neurological status and vision are the main contributors for challenging the patient with another immunosuppressive agent that has less neurological toxicity. Still studies have to be initiated to confirm the influence of PRES on transplant outcome.

Previous molecular analyses of α-thalassemia (α-thal) in the Republic of Macedonia have identified the following genetic defects: -α3.7 (rightward), -(α)20.5 and - -MED I deletions and Hb Icaria [α142, TermâLys (α2), HBA2: c.427T>A] and polyadenylation signal (polyA) [AATAAA>AATGAA (α2), HBA2: c.*92A>G] point mutations. Here, we report two unrelated patients from the Romani population in the Republic of Macedonia, homozygotes for the α2-globin gene variant Hb Agrinio [α29(B10)LeuâPro; HBA2: c.89T>C]. To date, Hb Agrinio has been described only in individuals of Greek, Cypriot and Spanish origin. Both of our patients had early presentation of the disease (3.5 years and 2 months, respectively) with frequent blood transfusions from early infancy. They have a severe intermediate phenotype of thalassemia (Hb H disease) with hemoglobin (Hb) levels of 7.8 and 7.7 g/dL, respectively. Although the HBA2: c.89T>C mutation results in an α+ allele, the severe phenotype of the homozygotes is due to the production of hyperunstable α chains that undergo post translational precipitation. This leads to a greater degree of red cell damage and hemolytic anemia. The detection of Hb Agrinio in two unrelated families of Romani ethnic origin, may suggest it is a founder mutation in this population living in the Republic of Macedonia. Considering the severity of the clinical presentation of the homozygotes or compound heterozygotes for this rare Hb variant, a targeted molecular screening for Hb Agrinio mutation carriers should be considered in all patients of Romani ethnic origin with manifested microcytosis.
