[Epidemiology of early infections after autologous hematopoietic stem cell transplantation. Analysis of data from 699 patients treated in a Hungarian centre]. / Autológossejt-transzplantációt követo korai infekciók epidemiológiája. Egy hazai centrumban kezelt 699 beteg adatainak elemzése.

Introduction: Autologous hemopoietic stem cell transplantation remains a promising therapy in certain malignant and non-malignant conditions. The procedure, however, will increase the risk of complications, most notably early and late infections. Aim: To analyze the frequency and spectrum of pathogens in early (<+100 days) post-transplant infections and to evaluate risk factors for mortality. Method: Prospectively collected data from 699 patients undergoing autologous hemopoietic stem cell transplantation between 2007 and 2014 at our center were retrospectively reviewed and analyzed. Results: The median age of 699 patients was 56 (interquartile range: 43-62) years, 54% (376) were male. 25 patients have been transferred to other centers and 19 patients were lost to follow up. Neutropenic fever occurred in 69.8% (488) of patients. In addition, 102 infectious episodes in 96 patients were identified. Most commonly bacteremia occurred (49 episodes) with a median onset of 7 (5-11) days. The majority (33/49) of bacteremias have been observed during the pre-engraftment period. Their incidence proved to be higher in patients with malignant lymphoma compared to individuals with plasma cell disorders (p = 0.0005, OR: 2.41, 95% CI: 1.49-3.99). 12 episodes of viral infections and 8 cases of proven or probable invasive mycoses have been identified. Among the 655 patients with complete follow up, 16 in-hospital deaths (2.4%) occurred, 8 of them were associated with infections. Survival was adversely affected by early infections (p = 0.0001). Conclusion: In autologous stem cell transplantation, microbiologically unconfirmed neutropenic fever is common. Documented early bacteremia, however, is infrequent. Lymphoma patients have a significantly higher chance to develop bloodstream infections compared to individuals with plasma cell disorders. Early infections decrease the chance of survival; thus, an effective prophylaxis and therapy remains of paramount importance. Orv Hetil. 2020; 161(3): 103-109.

Gynecological and obstetrical aspects of Enterobius vermicularis infection.

Enterobiasis is an easily recognizable and treatable disease with higher incidence among children. Based on these facts, its clinical importance is usually underestimated. This infection also occurs during adulthood and without treatment, it can cause severe complications in some rare cases. Unnoticed subclinical infection in women can lead to infertility and even to life-threatening conditions. It is also emphasized in this paper that the treatment of identified enterobiasis during pregnancy needs caution. After reviewing the current scientific literature, two gynecological cases are presented here.

Differentiation of obese patients at moderate or higher Findrisc score based on their atherogenic index.

OBJECTIVES: The purpose of this study was to reveal different subgroups of patients with at least moderate risk of developing diabetes in the next 10 years, based on clustering of cardiovascular risk factors. METHODS: We performed a one-center cross-sectional study of adult patients (n = 109, median age 45 years) with Findrisc score of above 11 out of 26 maximum. We included in the cluster analysis anthropometrics, lipid and carbohydrate parameters obtained in oral glucose tolerance test (OGTT), insulin, C-peptide, creatinine, C-reactive protein, liver enzymes, beta-cell function, insulin sensitivity and insulin resistance (HOMA calculations). We also evaluated the atherogenic index of plasma (AIP). RESULTS: We identified three metabolic phenotypes of patients with at least moderate Findrisc score-one 'male' (cluster AM, n = 24), and two 'female' phenotypes (cluster AW, n = 9 and cluster BW, n = 76). Men were almost homogenous for their metabolic phenotype, with lower fat percentage than women (p < .05). Most of the women (cluster BW, n = 76) presented with better metabolic pattern i.e. lower insulin resistance, lower C-reactive protein, lower degree of obesity and visceral fat rating (p < .05), despite the higher fat percentage (p < .05). Some of the women, however, (cluster AW, n = 9) presented with parameters very similar to that of men (cluster AM) and significantly higher than in cluster BW. Despite the lack of significant differences in lipid parameters among clusters, AIP was significantly lower in cluster BW (p < .05). CONCLUSION: Most of the women presented with clearly less unfavorable atherogenic risk than men. Two different phenotypes of obese women with at least moderate Findrisc score were revealed, and the level of inflammation seems to be the main discriminant factor. Larger prospective studies are required to elucidate whether those are really two different pathogenically phenotypes or if they belong to the same phenotype's continuum.

[Case of a diabetic man cured of rhinocerebral zygomycosis]. / Rhinocerebralis zygomycosisból gyógyult diabeteses férfi esete.

UNLABELLED: Zygomycosis (mucormycosis) is a rare, highly aggressive opportunistic fungal disease caused by saprophytic fungi, belonging to the division Zygomycota, class Zygomycetes. Patients with immunodeficiency, neutropenia, iron overload, hematological malignancies, as well as diabetics with ketoacidosis are typically affected. CASE PRESENTATION: Authors describe the case of an eighteen-year old man with poor compliance suffering from diabetes since the age of nine. He was admitted with ketoacidotic somnolence in severe general condition with unilateral periorbital erythematous edema. Though from nasal exudates gained by the fibero-endoscopic sinus surgery Methicillin-resistant Staphylococcus aureus and Pseudomas aeruginosa was cultured, amphotericin-B was administered as the medical history, clinical picture suggested presence of zygomycosis. An invasive infection caused by Rhizopus oryzae was confirmed by histology and microbiology. DISCUSSION: The combination of antifungal therapy, repeated surgical interventions and granulocyte colony-stimulating factor resulted in good clinical response. Four month after discharge he is alive and doing well.

Use of the BIOMIC Video System to evaluate the susceptibility of clinical yeast isolates to fluconazole and voriconazole by a disk diffusion method.

The ARTEMIS Global Antifungal Susceptibility Program provides the collection of epidemiological data and the results of the fluconazole and voriconazole susceptibility testing of yeast isolates. Participating in this study, a total of 7318 clinical yeast isolates were tested from different geographical areas in Hungary in the period 2001 to 2003. The species isolated most frequently was C. albicans (68.8%), followed by C. glabrata (11.8%), C. tropicalis (5.7%) and C. krusei (4.6%). Isolates of C. albicans, C. kefyr, C. lusitaniae, C. tropicalis and C. parapsilosis were highly susceptible to fluconazole (78.9-100%). The rates of isolation of fluconazole-resistant C. glabrata and C. krusei were higher in our study than the global mean in 2001 (28.2% and 87.5% vs. 18.3% and 70.2%, respectively). Differences were detected in the distribution of fluconazole-susceptibility data of C. glabrata isolates in the different counties of Hungary: most of the resistant isolates were observed in the eastern part of the country.

[Mucormycosis]. / Mucormycosis.

Over recent years the clinical importance of invasive fungal infections has significantly increased. Mucormycosis refers to a rare, life threatening, opportunistic disease caused by filamentous fungi of the order Mucorales. Most frequently mucormycosis occurs in patients with ketoacidotic diabetes and in neutropenic patients with acute leukaemia. This study of fifteen patients was conducted to evaluate the clinical characteristics of invasive mucormycosis, and goal was also to propose for an early diagnosis and management as survival can only be improved by aggressive surgery and antifungal therapy. In a retrospective analysis of the biopsy and autopsy records of the Department of Pathology at Szent László Hospital between 1992-2003 were evaluated fifteen histologically documented cases of mucormycosis. The underlying diseases were hematological malignancy with neutropenia in ten cases, chronic leukaemia with neutropenia, chronic leukaemia with latent diabetes mellitus and diabetes mellitus one case each. Three cases did not belong to any typical risk group. An in vivo diagnosis was made only in four patients with a rhinocerebral manifestation. Radical necrectomy and long-term antifungal therapy cured two of them. Two patients died of a generalised infection despite therapy. None of the systemic infections could be cured. The diagnosis was made post mortem in eleven patients. Selected clinical forms of mucormycosis are illustrated with short case reports.
