BACKGROUND: Chronic lymphocytic leukemia (CLL) is a common adult leukemia characterized by the accumulation of neoplastic mature B cells in blood, bone marrow, lymph nodes, and spleen. The disease biology remains unresolved in many aspects, including the processes underlying the disease progression and relapses. However, studying CLL in vitro poses a considerable challenge due to its complexity and dependency on the microenvironment. Several approaches are utilized to overcome this issue, such as co-culture of CLL cells with other cell types, supplementing culture media with growth factors, or setting up a three-dimensional (3D) culture. Previous studies have shown that 3D cultures, compared to conventional ones, can lead to enhanced cell survival and altered gene expression. 3D cultures can also give valuable information while testing treatment response in vitro since they mimic the cell spatial organization more accurately than conventional culture. METHODS: In our study, we investigated the behavior of CLL cells in two types of material: (i) solid porous collagen scaffolds and (ii) gel composed of carboxymethyl cellulose and polyethylene glycol (CMC-PEG). We studied CLL cells' distribution, morphology, and viability in these materials by a transmitted-light and confocal microscopy. We also measured the metabolic activity of cultured cells. Additionally, the expression levels of MYC, VCAM1, MCL1, CXCR4, and CCL4 genes in CLL cells were studied by qPCR to observe whether our novel culture approaches lead to increased adhesion, lower apoptotic rates, or activation of cell signaling in relation to the enhanced contact with co-cultured cells. RESULTS: Both materials were biocompatible, translucent, and permeable, as assessed by metabolic assays, cell staining, and microscopy. While collagen scaffolds featured easy manipulation, washability, transferability, and biodegradability, CMC-PEG was advantageous for its easy preparation process and low variability in the number of accommodated cells. Both materials promoted cell-to-cell and cell-to-matrix interactions due to the scaffold structure and generation of cell aggregates. The metabolic activity of CLL cells cultured in CMC-PEG gel was similar to or higher than in conventional culture. Compared to the conventional culture, there was (i) a lower expression of VCAM1 in both materials, (ii) a higher expression of CCL4 in collagen scaffolds, and (iii) a lower expression of CXCR4 and MCL1 (transcript variant 2) in collagen scaffolds, while it was higher in a CMC-PEG gel. Hence, culture in the material can suppress the expression of a pro-apoptotic gene (MCL1 in collagen scaffolds) or replicate certain gene expression patterns attributed to CLL cells in lymphoid organs (low CXCR4, high CCL4 in collagen scaffolds) or blood (high CXCR4 in CMC-PEG).

BACKGROUND: This study aimed to determine the differences in the cervical load and prevalence of Lactobacillus crispatus DNA, Lactobacillus iners DNA, Gardnerella vaginalis DNA, Sneathia sanguinegens DNA, and Ureaplasma species DNA between pregnant women with preterm prelabor rupture of membranes (PPROM) with and without a history of cervical excisional treatment. We also assessed the changes in the cervical load and prevalence of L. crispatus DNA, L. iners DNA, G. vaginalis DNA, S. sanguinegens DNA, and U. spp DNA. according to the cone length. METHODS: This retrospective study included 132 women with singleton pregnancies complicated by PPROM. For all women, information about the cervical loads of bacterial DNA corresponding to L. crispatus, L. iners, G. vaginalis, S. sanguinegens, and U. spp., which was assessed using PCR, was available. RESULTS: Women with a history of cervical excisional treatment had a higher cervical load of L. iners DNA (4.4 × 106 copies DNA/mL vs. 3.5 × 105 copies DNA/mL, p = .04) and a higher load and prevalence of U. spp. DNA (1.1 × 105 copies DNA/mL vs. 9.6 × 104 copies DNA/mL, p = .03; 2.7% vs. 0.5%, p = .04) than those without a history of cervical excisional treatment. In the subset of women with a history of cervical excisional treatment, those with a cone length 18 mm and more had a lower relative abundance of L. crispatus DNA (6% vs. 89%, p = .02), a higher load and relative abundance of L. iners DNA (1.1 × 107 copies DNA/mL vs. 8.2 × 105 copies DNA/mL, p = .04; 91% vs. 35%, p = .04), and higher loads of G. vaginalis DNA (7.6 × 104 copies DNA/mL vs. 3.2 × 102 copies DNA/mL, p = .02) than those with cone length < 18 mm. CONCLUSIONS: A history of cervical excisional treatment was associated with alterations in the cervical microbiota composition in pregnant women with PPROM.

BACKGROUND: Excisional treatment of cervical intraepithelial neoplasia or very early stages of cervical cancer increases the risk of preterm prelabor rupture of membranes in subsequent pregnancies. The risk increases with the length of the excised cone. The subset of cases with preterm prelabor rupture of membranes and a history of cervical excisional treatment could also be at higher risk of intraamniotic infection/inflammation. However, there is a paucity of relevant information on this subject. OBJECTIVE: This study aimed to assess the differences in the rates of intraamniotic infection/inflammation and early-onset neonatal sepsis between singleton preterm prelabor rupture of membranes pregnancies without and with a history of cervical excisional treatment, and to investigate the association between these complications of preterm prelabor rupture of membranes and the excised cone length. STUDY DESIGN: This retrospective cohort study included 770 preterm prelabor rupture of membranes pregnancies in which transabdominal amniocentesis was performed as part of standard clinical management to assess the intraamniotic environment. The maternal and perinatal medical records of all included women were reviewed to obtain information on the absence or presence of history of cervical excisional treatment and neonatal outcomes. Women whose records contained any information on history of cervical excisional treatment were contacted by phone and in writing to inform them of the study and request permission to collect relevant information from their medical records. Women were divided into 4 subgroups according to the presence of microorganisms and/or their nucleic acids (through culturing and molecular biology methods) in amniotic fluid and/or intraamniotic inflammation (through amniotic fluid interleukin-6 concentration evaluation): intraamniotic infection (presence of both), sterile intraamniotic inflammation (intraamniotic inflammation alone), microbial invasion of the amniotic cavity without inflammation (presence of microorganisms and/or their nucleic acids in amniotic fluid alone), and negative amniotic fluid for infection/inflammation (absence of both). RESULTS: A history of cervical excisional treatment was found in 10% (76/765) of the women. Of these, 82% (62/76) had a history of only 1 treatment, and information on cone length was available for 97% (60/62) of them. Women with a history of cervical excisional treatment had higher rates of intraamniotic infection (with, 25% [19/76] vs without, 12% [85/689]; adjusted odds ratio, 2.5; adjusted P=.004), microbial invasion of the amniotic cavity without inflammation (with, 25% [19/76] vs without, 11% [74/689]; adjusted odds ratio, 3.1; adjusted P<.0001), and early-onset neonatal sepsis (with, 8% [11/76] vs without, 3% [23/689]; adjusted odds ratio, 2.9; adjusted P=.02) compared with those without such history. Quartiles of cone length (range: 3-32 mm) were used to categorize the women into 4 quartile subgroups (first: 3-8 mm; second: 9-12 mm; third: 13-17 mm; and fourth: 18-32 mm). Cone length of ≥18 mm was associated with higher rates of intraamniotic infection (with, 29% [5/15] vs without, 12% [85/689]; adjusted odds ratio, 3.0; adjusted P=.05), microbial invasion of the amniotic cavity without inflammation (with, 40% [6/15] vs without, 11% [74/689]; adjusted odds ratio, 6.1; adjusted P=.003), and early-onset neonatal sepsis (with, 20% [3/15] vs without, 3% [23/689]; adjusted odds ratio, 5.7; adjusted P=.02). CONCLUSION: History of cervical excisional treatment increases risks of intraamniotic infection, microbial invasion of the amniotic cavity without inflammation, and development of early-onset neonatal sepsis in a subsequent pregnancy complicated by preterm prelabor rupture of membranes.

OBJECTIVE: The absence of microbial invasion of the amniotic cavity and intra-amniotic inflammation at the time of hospital admission is the most common condition associated with preterm prelabor rupture of membranes (PPROM). Although the intensity of intra-amniotic inflammatory response does not exceed the threshold for the diagnosis of intra-amniotic inflammation in this subgroup of PPROM, whether there could be differences in outcomes concerning the intensity of intra-amniotic inflammatory response remains unclear. Therefore, the main aims of this study on PPROM without microbial invasion of the amniotic cavity and intra-amniotic inflammation were (i) to characterize the association between the intensity of intra-amniotic inflammatory response, measured according to amniotic fluid interleukin (IL)-6 concentrations, and the presence of acute histological chorioamnionitis and acute inflammation in the amnion; (ii) to characterize the association between the intensity of intra-amniotic inflammatory response and fetal inflammatory response, and (iii) to describe the short-term morbidity of infants based on the intensity of intra-amniotic inflammatory response. METHODS: This retrospective study included 131 women with singleton pregnancies with PPROM without microbial invasion of the amniotic cavity and intra-amniotic inflammation between gestational ages of 24 + 0 and 36 + 6 weeks and who had delivered within 72 h of membrane rupture. Microbial invasion of the amniotic cavity was assessed based on a combination of cultivation and non-cultivation methods. Intra-amniotic inflammation was characterized based on the amniotic fluid IL-6 concentration. In addition, a histopathological assessment of the placenta was performed. Fetal inflammatory response syndrome was characterized according to IL-6 concentration in the umbilical cord blood of >11 pg/mL. Based on the quartiles of IL-6 concentrations in the amniotic fluid, these women were divided into four subgroups (from the lowest to the highest IL-6 concentrations). RESULTS: IL-6 concentrations in amniotic fluid were higher in women with acute histological chorioamnionitis (median: 819 pg/mL vs. 520 pg/mL; p = .003) and with acute inflammation of the amnion (median: 1116 pg/mL vs. 533 pg/mL; p = .0002) than in women without these complications. The rates of acute histological chorioamnionitis and acute inflammation of the amnion were the highest in the subgroup with IL-6 concentrations above the 75th percentile in amniotic fluid (chorioamnionitis, p = .02; amnion, p = .0002). No differences in IL-6 concentrations in amniotic fluid were identified between women with and without a fetal inflammatory response syndrome (p = .40). The rate of fetal inflammatory response syndrome did not vary among the amniotic fluid IL-6 quartile subgroups of women. Moreover, no differences were noted in short-term neonatal outcomes among the amniotic fluid IL-6 quartile subgroups. CONCLUSION: A higher intensity of the intra-amniotic inflammatory response, measured by amniotic fluid IL-6 concentrations, is associated with a higher rate of acute inflammatory lesions in the placenta in the subset of PPROM pregnancies without microbial invasion of the amniotic cavity and intra-amniotic inflammation.

OBJECTIVE: To assess the association between newborn birth weight and the presence of intra-amniotic infection, presence of sterile intra-amniotic inflammation, and absence of intra-amniotic inflammation in pregnancies with preterm labor with intact membranes. METHODS: A total of 69 pregnancies with preterm labor with intact membranes between gestational ages 22 + 0 and 34 + 6 weeks who delivered within seven days of admission were included in this retrospective cohort study. Transabdominal amniocentesis to determine the presence of microorganisms and/or their nucleic acids in amniotic fluid (through culturing and molecular biology methods) and intra-amniotic inflammation (according to amniotic fluid interleukin-6 concentrations) were performed as part of standard clinical management. The participants were further divided into three subgroups: intra-amniotic infection (presence of microorganisms and/or nucleic acids along with intra-amniotic inflammation), sterile intra-amniotic inflammation (intra-amniotic inflammation alone), and without intra-amniotic inflammation. Birth weights of newborns were expressed as percentiles derived from the INTERGROWTH-21st standards for (i) estimated fetal weight and (ii) newborn birth weight. RESULTS: No difference in birth weights, expressed as percentiles derived from the standard for estimated fetal weight, was found among the women with intra-amniotic infection, with sterile intra-amniotic inflammation, and without intra-amniotic inflammation (with infection, median 29; with sterile inflammation, median 54; without inflammation, median 53; p = 0.06). Differences among the subgroups were identified in the birth weight rates, expressed as percentiles derived from the standard for estimated fetal weight, which were less than the 10th percentile (with infection: 20%, with inflammation: 13%, without inflammation: 0%; p = 0.04) and 25th percentile (with infection: 47%, with inflammation: 31%, without inflammation: 9%; p = 0.01). No differences among the subgroups were observed when percentiles of birth weight were derived from the birth weight standard. CONCLUSIONS: The presence of intra-amniotic inflammatory complications in pregnancies with preterm labor with intact membranes prior to the gestational age of 35 weeks was associated with a higher rate of newborns with birth weight less than the 10th and 25th percentile, when percentiles of birth weight were derived from the standard for estimated fetal weight.

OBJECTIVE: To assess the association between the birth weight of newborns and microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation in pregnancies with preterm prelabor rupture of membranes. METHODS: A total of 528 pregnancies with preterm prelabor rupture of membranes were included in this retrospective cohort study. Transabdominal amniocentesis to determine the presence of MIAC (through culturing and molecular biology methods) and intra-amniotic inflammation (according to amniotic fluid interleukin-6 level) was performed as part of standard clinical management. Based on the presence of MIAC and/or intra-amniotic inflammation, the participants were divided into four subgroups: with intra-amniotic infection (presence of both), with sterile IAI (intra-amniotic inflammation alone), with colonization (MIAC alone), and with negative amniotic fluid (absence of both). Birth weights of newborns are expressed as percentiles derived from INTERGROWTH-21st standards for (i) newborn birth weight and (ii) estimated fetal weight. RESULTS: No differences in birth weights, expressed as percentiles derived from newborn weight standards (infection: median 52; sterile: median 54; colonization: median 50; negative amniotic fluid: median 51; p = .93) and estimated fetal weight standards (infection: median 47; sterile: median 51; colonization: median 47; negative amniotic fluid: median 53; p = .48) were found among the four subgroups. No differences in percentiles (derived from both standards) were found in the subset of participants who delivered within 72 h after rupture of membranes (newborn weight standard, p = .99; estimated fetal weight standard, p = .81). CONCLUSIONS: No association was identified between the birth weight of newborns and the presence of intra-amniotic inflammatory and infection-related complications in pregnancies with preterm prelabor rupture of membranes.

OBJECTIVE: To determine the prevalence of Ureaplasma spp. DNA and its load in the cervical fluid in women with preterm labor with intact membranes (PTL) complicated by intra-amniotic infection (the presence of both microbial invasion of the amniotic cavity and intra-amniotic inflammation) or sterile intra-amniotic inflammation (the presence of intra-amniotic inflammation alone). METHODS: Overall, 115 women with singleton pregnancies complicated by PTL between gestational ages of 22 + 0 and 34 + 6 weeks were included in this study. Paired amniotic and cervical fluid samples were collected at the time of admission via transabdominal amniocentesis using a Dacron polyester swab. Microbial invasion of the amniotic cavity was diagnosed based on a combination of culture and molecular biology methods. Intra-amniotic inflammation was determined based on the concentration of interleukin-6 in the amniotic fluid. Bacterial and Ureaplasma spp. DNA loads were assessed in the cervical fluid using PCR. RESULTS: Intra-amniotic infection and sterile inflammation were identified in 14% (16/115) and 25% (29/115) of the women, respectively. Ureaplasma spp. DNA in the cervical fluid was identified in 51% (59/115) of women. The presence of Ureaplasma spp. DNA in the cervical fluid was higher in women with intra-amniotic infection (75% (12/16)) and sterile intra-amniotic inflammation (76% (22/29)) than in women without intra-amniotic inflammation (36% (25/70); p = .0002). Concurrent presence of Ureaplasma spp. and Mycoplasma hominis DNA was higher in women with intra-amniotic infection (42% (5/12)) than women with sterile intra-amniotic inflammation (7% (2/29)) and women without intra-amniotic inflammation (7% (5/70); p = .001). There were no differences in the load of Ureaplasma spp. DNA in the cervical fluid among women with intra-amniotic infection, sterile intra-amniotic inflammation, and those without intra-amniotic inflammation (median values; infection: 1.2 × 104 copies DNA/mL; sterile: 5.0 × 105 copies DNA/mL; without: 8.4 × 104 copies DNA/mL; p = .18). CONCLUSIONS: In PTL , both forms of intra-amniotic inflammation were associated with a higher prevalence of Ureaplasma spp. DNA in the cervical fluid. The presence of intra-amniotic infection was related to a higher rate of concurrent Ureaplasma spp. and M. hominis DNA in the cervical fluid.

OBJECTIVE: Macrophage inflammatory protein 1α is a chemokine produced by various immune, epithelial, mesothelial, and fibroblast cells after exposure to bacterial lipopolysaccharide or pro-inflammatory molecules. The primary aim of this study was to determine MIP-1α concentrations in amniotic and cervical fluids from pregnancy with spontaneous preterm labor with intact membranes (PTL) with respect to the presence of intra-amniotic infection (both microbial invasion of the amniotic cavity and intra-amniotic inflammation) and sterile intra-amniotic inflammation (intra-amniotic inflammation alone). The secondary aim was to assess the diagnostic indices of MIP-1α in predicting intra-amniotic infection. MATERIALS AND METHODS: Seventy-four women with PTL were included in this study. Paired amniotic and cervical fluid samples were obtained using transabdominal amniocentesis and a Dacron polyester swab, respectively. Microbial invasion of the amniotic cavity was diagnosed based on a combination of culture and molecular biology methods. The concentration of IL-6 in the amniotic and cervical fluids was measured using an automated electrochemiluminescence immunoassay method. Intra-amniotic inflammation was defined as an amniotic fluid IL-6 concentration of ≥3000 pg/mL. The MIP-1α concentrations in the samples were assessed using an enzyme-linked immunosorbent assay. RESULTS: A difference in amniotic fluid MIP-1α was observed among women with intra-amniotic infection, sterile intra-amniotic inflammation, and negative amniotic fluid (infection: median 1779.0 pg/mL; sterile, median 102.7 pg/mL; negative, median 19.9 pg/mL; p < .0001). No difference in the concentrations of MIP-1α was identified in cervical fluid after adjustment for gestational age at sampling (infection: median 77.7 pg/mL, sterile: median 152.7 pg/mL, negative: median 18.0 pg/mL; p = .30). The presence of intra-amniotic infection was associated with elevated MIP-1α concentrations in amniotic fluid (presence: 1779.0 pg/mL vs. absence: 26.3 pg/mL, p < .0001, area under receiver operating characteristic curve = 0.87). CONCLUSIONS: In PTL pregnancies with the presence of intra-amniotic infection, the concentration of MIP-1α is elevated in amniotic fluid but not in cervical fluid. Amniotic fluid MIP-1α may provide a useful marker for intra-amniotic infection in women with PTL.

Objectives: To determine the prevalence and load of Ureaplasma spp. DNA in the cervical fluid of women with singleton pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to intra-amniotic infection, sterile intra-amniotic inflammation, and colonization of the amniotic fluid. Methods: A total of 217 women with PPROM between gestational ages 24 + 0 and 33 + 6 weeks were included in this study. Paired amniotic and cervical fluid samples were collected at the time of admission via transabdominal amniocentesis and using a Dacron polyester swab, respectively. Microbial invasion of the amniotic cavity was diagnosed using a combination of culture and molecular biology methods. Intra-amniotic inflammation was determined based on the concentration of interleukin-6 in the amniotic fluid. Based on the presence or absence of these conditions, the women were stratified into the following subgroups: intra-amniotic infection (with both), sterile intra-amniotic inflammation (with inflammation only), colonization (with microorganisms only), and negative amniotic fluid (without either). The Ureaplasma spp. DNA load in the cervical fluid was assessed using PCR. Results:Ureaplasma spp. DNA in the cervical fluid was found in 61% (133/217) of the women. Women with negative amniotic had similar prevalence of Ureaplasma spp. DNA in cervical fluid (55%) to those with sterile intra-amniotic inflammation (54%) but lower than those with intra-amniotic infection (73%) and colonization (86%; p < 0.0001). Women with negative amniotic fluid had a lower load of Ureaplasma spp. DNA in their cervical fluid (median: 4.7 × 103 copies of DNA/ml) than those with intra-amniotic infection (median: 2.8 × 105 copies DNA/ml), sterile intra-amniotic inflammation (median: 5.3 × 104 copies DNA/ml), and colonization (median: 1.2 × 105 copies DNA/mL; p < 0.0001). Conclusion: In conclusion, in PPROM at <34 weeks, the presence of intra-amniotic infection, sterile intra-amniotic inflammation, or colonization of the amniotic fluid was associated with a higher prevalence and/or load of Ureaplasma spp. DNA in the cervical fluid than the absence of intra-amniotic complications.
