The efficacy of Allium ampeloprasum L. in reducing neutrophil recovery time in childhood cancer with febrile neutropenia: a randomized, double-blind, placebo-controlled trial

INTRODUCTION

Febrile neutropenia is a serious complication of cancer chemotherapy that can result in delays in treatment. This study evaluates the efficacy of A. ampeloprasum L. at neutrophil recovery time in children with chemotherapy-associated febrile neutropenia.

METHODS

This single-center, parallel-group, double-blind, randomized clinical trial was conducted at an oncology hospital. Patients selected among childhood cancers with febrile neutropenia. Overall, 97 febrile neutropenic children were enrolled. The intervention group (n=49) was given A. ampeloprasum L. in capsules (500 mg twice daily) for seven days plus supportive care. The control group (n=48) was treated similarly with supportive care and placebo capsules. Total white blood cell (WBC) and absolute neutrophil counts (ANC) were checked daily and neutrophil recovery time in both groups was compared.

RESULTS

Patients in the intervention group experienced shorter neutrophil recovery compared to the control group (4.02 ± 2.32 days vs. 6.38 ± 2.80 days, respectively, P less than 0.001). The intervention group was discharged from the hospital earlier than the control group with a mean of two days, but it did not reach statistical significance (P=0.133). Mean WBC and ANC were not significantly different in the two groups. Herbal medicine was well tolerated, and no adverse effect was reported.

CONCLUSIONS

A fresh, lyophilized extract from deciduous leaves of A. ampeloprasum L. can effectively shorten the ANC recovery time leading to an earlier release from the hospital. The trial was registered in the Iranian Registry of Clinical Trials with registration No. IRCT2015051615666N2 (http://www.irct.ir/).

Cardioprotective effects of deferoxamine in acute and subacute cardiotoxicities of doxorubicin: a randomized clinical trial

BACKGROUND

Cardiotoxicity is a major concern following doxorubicin (DOX) use in the treatment of malignancies. We aimed to investigate whether deferoxamine (DFO) can prevent acute cardiotoxicity in children with cancer who were treated with DOX as part of their chemotherapy.

RESULTS

Sixty-two newly-diagnosed pediatric cancer patients aged 2-18 years with DOX as part of their treatment regimens were assigned to three groups: group 1 (no intervention, n = 21), group II (Deferoxamine (DFO) 10 times DOX dose, n = 20), and group III (DFO 50 mg/kg, n = 21). Patients in the intervention groups were pretreated with DFO 8-h intravenous infusion in each chemotherapy course during and after completion of DOX infusion. Conventional and tissue Doppler echocardiography, serum concentrations of human brain natriuretic peptide (BNP), and cardiac troponin I (cTnI) were checked after the last course of chemotherapy. Sixty patients were analyzed. The level of cTnI was < 0.01 in all patients. Serum BNP was significantly lower in group 3 compared to control subjects (P = 0.036). No significant differences were observed in the parameters of Doppler echocardiography. Significant lower values of tissue Doppler late diastolic velocity at the lateral annulus of the tricuspid valve were noticed in group 3 in comparison with controls. By using Pearson analysis, tissue Doppler systolic velocity of the septum showed a marginally significant negative correlation with DOX dose (P = 0.05, r = - 0.308). No adverse effect was reported in the intervention groups.

CONCLUSIONS

High-dose DFO (50 mg/kg) may serve as a promising cardioprotective agent at least at the molecular level in cancer patients treated with DOX. Further multicenter trials with longer follow-ups are needed to investigate its protective role in delayed DOX-induced cardiac damage. Trial registration IRCT, IRCT2016080615666N5.

An evaluation of ascitic calprotectin for diagnosis of ascitic fluid infection in children with cirrhosis

Background

The most common infection in children with the hepatic disease with or without cirrhotic ascites is spontaneous bacterial peritonitis (SBP), which occurs in the absence of an evident intra-abdominal source of infection. The present study aims to assess the value of calprotectin in ascitic fluid in the diagnosis of ascitic fluid infection in children with liver cirrhosis.

Materials and methods

In this cross-section study, 80 children with underlying liver disease who attended the Hepatology and Emergency Department in Shiraz University Hospitals were studied. All the patients were evaluated by a thorough history, clinical examination, laboratory investigations, diagnostic paracentesis with PMNLs count, and Calprotectin, which was measured in 1 mL ascitic fluid by ELISA.

Results

Thirty-five patients (43.75%) were diagnosed with ascitic fluid infection. Of these children 6 cases had positive ascitic fluid culture (SBP). Calprotectin was high in AFI patients with a statistically significant difference in AFI patients compared to non-AFI patients. The cut-off levels were 91.55 mg /L and the area under the curve was 0.971. So it can serve as a sensitive and specific diagnostic test for detection of AFI in children with underlying liver disease.

Conclusion

Elevated ascitic calprotectin levels in cirrhotic patients are a diagnostic and reliable marker for the detection of AFI and are considered a surrogate marker for PMN.

Feasibility and Therapeutic Potential of 177Lu-Fibroblast Activation Protein Inhibitor-46 for Patients With Relapsed or Refractory Cancers: A Preliminary Study

INTRODUCTION

Fibroblast activation protein (FAP) is a member of the serine protease family and has a high expression in the stroma of approximately 90% of epithelial malignancies. The present investigation aimed to assess the feasibility, safety, and dosimetry data of 177Lu-FAPI-46 in diverse malignancies.

PATIENTS AND METHODS

Patients with advanced cancers with nonoperable tumors, or tumors refractory to conventional therapies, were enrolled. Treatment included escalating doses of 177Lu-FAPI-46 (1.85-4.44 GBq) per cycle using a combination of clinical and statistical expertise design, and intervals of 4 to 6 weeks were considered between the cycles. Biodistribution and dosimetry were examined by whole-body scans. We applied the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 to measure peptide-targeted radionuclide therapy (PTRT)-associated toxicity.

RESULTS

A total of 21 patients (11 females and 10 males) with a median age of 50 years (range, 6-79 years) were investigated. Of 21 participants, 18 cases were selected for PTRT. Overall, 36 PTRT cycles were performed. The median number of PTRT cycles and the median injected amount of activity in each cycle were 2 and 3.7 GBq, respectively. The dosimetric analysis revealed median absorbed doses of 0.026, 0.136, 0.886, and 0.02 with ranges of 0.023-0.034, 0.001-0.2, 0.076-1.39, and 0.002-0.2 mGy/MBq for the whole body, liver, kidneys, and spleen, respectively. The therapy was well tolerated in almost all patients.

CONCLUSIONS

The findings of this preliminary investigation might indicate the potential feasibility and safety of PTRT using 177Lu-FAPI-46 for different aggressive tumors. Moreover, the current study could be beneficial in determining the suitable amount of activity for a phase 2 study.

Study of the Serum Immunoglobulin and Cell-Mediated Immunity in Patients with Congenital Severe Hemophilia

BACKGROUND

It has been shown that a close relationship exists between the immune system and coagulation cascade. Hemophilia A is an X-linked, recessive bleeding disorder caused by deficiency of functional plasma clotting factor VIII that is classically treated with factor VIII replacement therapy. Despite this, some patients produce inhibitors or antibodies against epitopes of infused factor VIII, indicating the activation of the adaptive immune system. The aim of this study was to evaluate the change in the T cell frequency and serum immunoglobulin level in patients with congenital hemophilia A, especially those who produce inhibitors against factor VIII.

METHODS

This is a cross-sectional, case-control study on congenital hemophilia A patients with severe factor VIII deficiency. Twenty-eight hemophilia A male patients were randomly selected along with twenty age-matched healthy males, as the control group. Serum immunoglobulin concentration was measured by nephelometry (for IgG, IgA and IgM) and enzyme-linked immunosorbent assay (ELISA) (for IgE) and the frequency of CD4+ and CD8+ T cells were calculated using a flow cytometry method.

RESULTS

Serum IgG was significantly higher in hemophilic patients compared to controls (14.35 ± 3.60, vs. 12.4 ± 1.72, p = 0.014). Among IgG subtypes, the IgG1 antibody was significantly higher in hemophilia patients than control group (p < 0.001). The frequency of CD4+ as well as CD8+ T cells did not significantly differ between patients and control group (p > 0.05). There was no significant difference between patients with and without inhibitors re-garding serum immunoglobulin level, different IgG subtypes, the frequency of CD4+ and CD8+ T cells as well as CD4/CD8 ratio (p > 0.05).

CONCLUSIONS

Patients with hemophilia A have high levels of serum immunoglobulin especially IgG1. Therefore, further larger studies along with close observation and evaluation of the presence of serum inhibitor is recommended every 3 months.

Extramedullary manifestations in acute lymphoblastic leukemia in children: a systematic review and guideline-based approach of treatment

OBJECTIVE

Acute lymphoblastic leukemia (ALL) may present with signs and symptoms related to extramedullary involvement, therefore, leads to delayed diagnosis of ALL in children. This study aims to consider the extramedullary manifestations of ALL in children and their proper treatment.

METHOD

The databases were searched for all relevant subjects including "acute lymphoblastic leukemia", "clinical presentation", "unusual presentation", "childhood acute lymphoblastic leukemia", "presenting features of ALL", "extramedullary presentation", and "atypical presentation" from April 1968 to June 2020. The Inclusion criteria for this review study were all cases reported, case series, and studies about extramedullary presentations of ALL in pediatrics. Eighty-seven studies had inclusion criteria. All reported studies were analyzed given their extramedullary presentations, age, sex, treatment option, and prognostic factors. A two-sided P-value less than 0.05 was considered statistically significant.

RESULT

In this review study, the extramedullary initial signs and symptoms of ALL were related to musculoskeletal system 17 (19.5%) especially bony symptoms and hypercalcemia. The additional extramedullary presentations of ALL in order of frequency include; renal involvement, 17 (19.5%), hepatic symptom 12 (13.8%), orbital presentation 10 (11.5%), neurologic signs 8 (9%), dermatological manifestations 5 (5.8%), oral presentations 5 (5.8%), hypereosinophilia 5 (5.8%), abdominal manifestation 3 (3.5%), pericardial involvement 2 (2.3%), and the other miscellaneous presentations 3 (3.5%).

CONCLUSION

The clinicians must become familiar with these extramedullary presentations of ALL in pediatrics to avoid the delayed diagnosis of this disease and increase the probable chance of survival by early detection.

A novel frame-shift deletion in FANCF gene causing autosomal recessive Fanconi anemia: a case report

Background

Fanconi anemia (FA) is a heterogeneous genetic disorder characterized by congenital anomalies, early-onset bone marrow failure, and a high predisposition to cancers. Up to know, different genes involved in the DNA repair pathway, mainly FANCA genes, have been identified to be affected in patients with FA.

Case presentation

Here, we report clinical, laboratory and genetic findings in a 3.5-year-old Iranian female patient, a product of a consanguineous marriage, who was suspicious of FA, observed with short stature, microcephaly, skin hyperpigmentation, anemia, thrombocytopenia and hypo cellular bone marrow. Therefore, Next Generation Sequencing was performed to identify the genetic cause of the disease in this patient. Results revealed a novel, private, homozygous frameshift mutation in the FANCF gene (NM_022725: c. 534delG, p. G178 fs) which was confirmed by Sanger sequencing in the proband.

Conclusion

Such studies may help uncover the exact pathomechanisms of this disorder and establish the genotype-phenotype correlations by identification of more mutations in this gene. It is the first report of a mutation in the FANCF gene in Iranian patients with Fanconi anemia. This new mutation correlates with a hematological problem (pancytopenia), short stature, and microcephaly and skin hyperpigmentation. Until now, no evidence of malignancy was detected.

Successful treatment of refractory metastatic neuroblastoma with panobinostat in combination with chemotherapy agents and iodine-131-meta-iodobenzylguanidine therapy

INTRODUCTION

Neuroblastoma commonly required multimodal therapy containing surgery, chemotherapy, radiotherapy, and immunotherapy.

CASE REPORT

In our case, who had refractory metastatic neuroblastoma, we use histone deacetylase inhibitor (panobinostat) in combination with chemotherapy agents and iodine-131-meta-iodobenzylguanidine (MIBG) therapy.

MANAGEMENT AND OUTCOME

This approach leads to successfully treat the patient. MIBG scan and bone marrow examination after therapy revealed no evidence of tumor. Now, she underwent autologous transplantation six months ago and free of tumor.

CONCLUSION

Panobinostat can cause apoptosis induction in refractory metastatic neuroblastoma in combination with MIBG therapy and chemotherapy.

Gynecomastia as a late complication of childhood cancer and its treatment that can affect the quality of life of male survivors

Childhood cancer is relatively rare, and nowadays it is curable in more than 80% of children. Childhood cancer therapy is directed not only at improving survival but recently, we also concentrate on reducing late effects. We want children who have a diagnosis of cancer to survive and have an excellent quality of life. Gynecomastia and fertility outcome of the survivors of childhood malignancies should be considered in the follow-up of teen agers and young adults and should be approached in an accurate manner and managed in comprehensive teams.

Effect of ursodeoxycholic acid and vitamin E in the prevention of liver injury from methotrexate in pediatric leukemia

BACKGROUND/AIMS

Ursodeoxycholic acid (UDCA) and antioxidants such as vitamin E are considered to have a protective role in preventing chemotherapy-induced liver damage. The aim of this study was to assess the efficacy of these agents for hepatoprotection in pediatric patients with B-cell acute lymphoblastic leukemia (ALL), who were treated with methotrexate in their maintenance phase of treatment.

MATERIALS AND METHODS

Eighty children with B-cell ALL were randomly divided into four groups. Group 1 was administered oral vitamin E (400 mg/day); group 2 was administered oral UDCA (15 mg/kg/day); group 3 was administered a combination of the two drugs; and group 4 served as a control group and was administered no drug except their chemotherapy drugs. Complete blood count, liver function test, liver ultrasonography, and liver fibroscan were requested, and the results were compared.

RESULTS

Group 1 showed a slight increase in total bilirubin levels compared to baseline levels during the study (P=0.036). Group 2 showed a decline in aspartate aminotransferase and alanine aminotransferase levels during the study and at 6 months after discontinuing the drug; however, these differences were not statistically significant (P=0.051 and 0.083, respectively). None of the patients showed the evidence of significant fibrosis on liver fibroscan. Eight patients showed some evidence of mild-to-moderate fibrosis (F1, F2), but the results were not different between the groups as well as between pre- and post-study periods in each group.

CONCLUSION

Low-dose methotrexate does not cause significant liver fibrosis in pediatric leukemia. UDCA and vitamin E have minimal roles in hepatoprotection among pediatric patients with ALL.

Rigler Sign in a Child With Posttransplant Lymphoproliferative Disease: A Sign That Should Not Be Missed

Rigler sign is a double wall sign suggesting pneumoperitoneum and intestinal perforation, and it needs emergency surgical treatment. Early diagnosis of intestinal perforation by clinical symptoms, presence of Rigler sign in abdominal radiography, and then early surgical treatment can reduce mortality. Here, we report a patient with Crigler-Najjar syndrome who underwent liver transplant and then developed posttransplant lymphoproliferative disease and received chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab. She was referred to the emergency department due to abdominal distension with positive Rigler sign in abdominal radiography; intraoperative findings revealed intestinal perforation. Pediatricians and surgeons should be aware of Rigler sign so that it is diagnosed early and emergency surgical treatment can be performed.

Skin manifestation of methylmalonic acidemia: case report and review of the literature

Skin manifestations, including scalded skin, desquamation, and chronic periorificial dermatitis, are rare clinical signs in patients with methylmalonic acidemia. This condition may be due to enzyme deficiency or multi-nutrient deficiency because of nutritional restriction. Bullous skin lesion is very rare in these patients and consequently, this type of skin lesion can be the presenting sign of methylmalonic acidemia.

Epstein-Barr viral load before a liver transplant in children with chronic liver disease

OBJECTIVES

Many children with chronic liver disease require a liver transplant. These patients are prone to various infections, including Epstein-Barr virus infection. This study sought to measure the Epstein-Barr viral load by polymerase chain reaction before a liver transplant.

MATERIALS AND METHODS

This cross-sectional study was done at the Shiraz University of Medical Sciences, Shiraz, Iran, in 2011. All patients were aged younger than 18 years with chronic liver disease and were candidates for a liver transplant at the Shiraz Nemazee Hospital Organ Transplant Center. They had been investigated regarding their demographic characteristics, underlying disease, laboratory findings, and Epstein-Barr viral load by real-time TaqMan polymerase chain reaction.

RESULTS

Ninety-eight patients were studied and the mean age was 6.5 ± 5.9 years. Cryptogenic cirrhosis was the most-prevalent reason for liver transplant, and the death rate before a transplant was 15%. Among the study subjects, 6 had measurable Epstein-Barr viral load by polymerase chain reaction before the transplant, and 4 of them had considerably higher Epstein-Barr viral loads (more than 1000 copies/mL).

CONCLUSIONS

With respect to the close prevalence of posttransplant lymphoproliferative disease (6%) and the high Epstein-Barr viral load in the patients before a transplant (4%), high pretransplant Epstein-Barr viral load can be considered a risk factor for posttransplant lymphoproliferative disorder.

Effects of omega-3 polyunsaturated Fatty acids on heart function and oxidative stress biomarkers in pediatric patients with dilated cardiomyopathy

OBJECTIVES

Dilated cardiomyopathy is the most prevalent type of cardiomyopathy in children, which results in congestive heart failure and causes significant morbidity and mortality. This study, aims to investigate the effect of supplementation with omega-3 polyunsaturated fatty acids (n-3 PUFA) on heart function and oxidative stress biomarkers in these patients.

METHODS

The present research was a case-control study on pediatric patients with dilated cardiomyopathy, who received n-3 PUFA and anti-failure therapy for 6 months (group 1, n = 6), or anti-failure therapy alone for 6 months (group 2, n = 6), as well as age matched normal individuals (group 3, n = 6), and evaluated the cardiac function and biomarkers of oxidative stress.

RESULTS

Echocardiographic parameters, such as left ventricular ejection fraction, shortening fraction, tissue Doppler Ea and Aa waves of lateral annulus of tricuspid valve, and Ea and S wave of septum, were significantly improved in group 1 after n-3 PUFA compared to pre- treatment status, while they were not changed after treatment in group 2. Antioxidant enzymes, including catalase and glutathione peroxidase activities in erythrocytes were slightly decreased, while plasma 8-iso-prostaglandin F2α concentrations were somewhat increased in group 1 compared to groups 2 and 3, however these changes were not statistically significant. Total antioxidant capacity of plasma was similar in all 3 groups.

CONCLUSIONS

The results indicate that some echocardiographic parameters were significantly improved in patients receiving omega-3 fish oil. However, omega-3 had no significant effect on oxidative stress biomarkers.
