    A comparison of the mixed and sequential use of acetaminophen and dexketoprofen in painful vaso-occlusive crises
    (Springer Heidelberg, 2024) Kacmaz, Murat; Ilhan, Gul
    Purpose Opioids are widely used to treat painful vaso-occlusive crises (VOC) in sickle cell disease (SCD). However, due to opioids' significant adverse effect profiles, the search for alternative therapies continues from the past to the present. The study aimed to investigate the efficacy of acetaminophen and dexketoprofen in the treatment of painful VOC.Methods This study is a single-center, prospective, non-randomized, single-blinded, controlled study. The study comprised two groups: the first administered acetaminophen and dexketoprofen mixed group, while the second received them sequential group. Opioids were used in patients with persistent pain despite these analgesics. Demographic and laboratory information, pain scores, opioid requirement, dose amount, side effects, and length of hospital stay of the patients were recorded.Results The study comprised 56 (100%) patients with painful VOC, 29 (51.8%) from the mixed group, and 27 (48.2%) from the sequential group. Opioid use was seen in 16 (55.2%) patients in the mixed group and 21 (77.8%) patients in the sequential group (p = 0.074). The median amount of opioid used was significantly lower in the mixed group than in the sequential group (p < 0.001). Also, the median length of hospital stay was significantly lower in the mixed group than in the sequential group (p < 0.001).Conclusion Our study suggests that administering acetaminophen and dexketoprofen in the mix for the treatment of painful VOC in patients with SCD may be a more efficient approach compared to sequential administration. This approach appears to reduce opioid usage and shorten hospital stays.

    Effects of Different Doses of Oral Iron on Hepcidin and Treatment Response in Iron Deficiency Anemia
    (Springer India, 2024) Beyler, Ozlem; Demir, Cengiz; Demircan, Vehbi; Kacmaz, Murat
    IntroductionIron deficiency anemia (IDA) is a common health problem. The hepcidin hormone is the main regulator of systemic iron balance. The body responds to IDA by decreasing hepcidin. This study investigated how different iron supplementation regimens affect hepcidin levels in women with IDA. 87 female participants aged 18-45 years with hemoglobin < 10 g/dL and serum ferritin < 20 ng/ml were assigned to receive iron therapy every other day, once daily, or twice daily. Hemogram, serum iron, serum iron binding capacity, ferritin, hepcidin, and C-reactive protein values were measured at baseline and on the 15th and 90th days of treatment in all groups. On the seventh day, no significant difference was found between the once-daily and twice-daily groups (p = 0.42) in reticulocyte counts. By the 15th day, hemoglobin and MCV levels showed significant improvement in the twice-daily group compared to the other groups (p < 0.01). At the third month, ferritin levels were significantly higher in the twice-daily group compared to the every-other-day and once-daily groups (p = 0.03). No significant differences were observed in hepcidin levels at three months across all groups. The study concludes that twice-daily iron supplementation results in the most significant hematological improvements but with increased gastrointestinal side effects. These findings underscore the importance of tailoring iron dosing schedules to individual patient needs. In cases where rapid haemoglobin response is required, twice-daily dosing may provide superior results. Conversely, once-daily dosing may be preferred if tolerable anemia can be maintained. Every other day dosing, although associated with fewer side effects and better tolerability, may not provide adequate support for erythropoiesis.

    Genotype-phenotype correlation and mutation spectrum of HBB gene in the Hatay province of Turkey
    (Cukurova Univ, Fac Medicine, 2024) Kacmaz, Murat; Asikovali, Semih
    Purpose: Thalassemia carriage and hemoglobinopathies are quite common disorders in Turkey, especially in the cukurova region, including Hatay province. Due to the high case population and genetic diversity in our region, this study aimed to investigate the genotype-phenotype correlation in the HBB gene. Materials and Methods: The data of patients who applied to Hatay Mustafa Kemal University Medical Genetics or Hematology Clinic between January 2010 and November 2022 were evaluated retrospectively. Results: A total of 40 (100%) cases, comprising 25 (62.5%) homozygous and 15 (37.5%) compound heterozygous genotypes, were included in the study based on the mutation profiles in the HBB gene. In the analysis of the cases, it was seen that there were 17 different variants and 22 distinct genotypes. The three most common variants identified in this study were IVS-I-6 (T>C), IVS-I-1 (G>A), and IVS-II-848 (C>A). Of the cases with homozygous genotypes, 13 (52%) had the IVSI-6 (T>C) variant. The most frequent genotypes observed in cases with compound heterozygous genotype were IVSI-6 (T>C)/IVS-I-110 (G>A), IVS-I-6 (T>C)/Hb Knossos, and IVS-I-110 (G>A)/-101 C>T, each in 2 (13%) cases. Conclusion: This study provides information on the phenotypic characteristics of very rare genotypes. We think that this information will be very beneficial, especially for clinicians interested in prenatal diagnosis, preimplantation genetic diagnosis, and postnatal genetic counseling.

    The role of pentraxin 3 and oxidative status in the prognosis of multiple myeloma
    (Sage Publications Ltd, 2024) Oguzman, Hamdi; Kacmaz, Murat
    Multiple myeloma (MM) is a bone marrow malignancy characterized by plasma cell proliferation. It was aimed to investigate pentraxin 3 (PTX3) levels, oxidative/antioxidative status, and their correlation in MM. In the study, four groups were established, including newly diagnosed MM (NDMM), MM in remission (Rem-MM), relapsed/refractory MM (RRMM) patients, and a healthy control group. PTX3 levels were measured using enzyme-linked immunosorbent assay, and the total antioxidant status (TAS) and total oxidant status (TOS) were assessed with an autoanalyzer. The oxidative stress index (OSI) was calculated using the formula: OSI (arbitrary unit) = TOS (mu mol H2O2 Eq/L)/TAS (mmol Trolox Eq/L) x 100. The study involved comparing PTX3, TAS, TOS, and OSI levels among these four groups. PTX3 levels were significantly elevated in NDMM and RRMM groups compared to controls and the Rem-MM group (NDMM vs control; p < 0.001, NDMM vs Rem-MM; p < 0.001, RRMM vs control; p < 0.001, and RRMM vs Rem-MM; p = 0.006). TAS was higher in NDMM and RRMM groups versus controls (p = 0.009 and p < 0.001, respectively), and TOS was higher in rem-MM group versus NDMM and control groups (p < 0.001 and p = 0.016, respectively). OSI was higher in the Rem-MM group than in NDMM and RRMM groups (p < 0.001 and p = 0.009, respectively). Multivariate analysis confirmed associations between MM groups and PTX3 levels. Receiver operating characteristic analysis revealed high specificity (90%) and sensitivity (79%) for PTX3 in NDMM at a >0.56 ng/mL cut-off value. This study suggests that PTX3 levels may have diagnostic and prognostic potential in MM and its relationship with oxidative stress requires further exploration.
