ABSTRACT

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is a rare, potentially lethal disorder, characterized by a dysregulation of the immune response, leading to a severe inflammatory syndrome. Epstein-Barr virus (EBV)-associated HLH is a form of secondary HLH, a fulminant presentation of an otherwise benign viral infection. PATIENT CONCERNS: We report the case of a 3-year-old girl who presented with fever, signs of accute upper respiratory tract infection and spontaneous, disseminated ecchymoses. Initial laboratory tests revealed pancytopenia. A bone marrow aspirate was performed, which revealed megaloblasts and numerous macrophages, with abundant foamy cytoplasm. Megaloblastic anemia was excluded, as the levels of vitamin B12 and folic acid were both within normal ranges. DIAGNOSIS: Hyperferritinemia, hypertriglyceridemia, hypofibrinogenemia, and splenomegaly were relevant criteria for the diagnosis of HLH, in accordance with the bone marrow specimen. Positive immunoglobulin M antibodies for EBV were supportive of an acute EBV infection, which was the most probable trigger of HLH. The patient's evolution was complicated by a massive epistaxis, in the context of thrombocytopenia which required plasma, thrombocyte, and erythrocyte substitutes. INTERVENTION: The patient was started on a treatment regimen of 8 weeks with etoposide and dexamethasone. OUTCOME: Her evolution was favorable, the treatment being successful in remission induction. CONCLUSION: Our case emphasizes the diagnostic challenges of HLH, in a patient with EBV infection whose evolution was hindered by a severe epistaxis, with potentially fatal outcome.

ABSTRACT

RATIONALE: Non-Hodgkin lymphoma remains an unpredictable condition in pediatric patients. PATIENT CONCERNS: Our first case describes an 8-year-old boy with a history of iron deficiency anemia, admitted in our clinic for recurrent abdominal pain, weight loss, loss of appetite, diarrheic stools, and fever. The second case also describes an 8-year-old boy admitted for abdominal pain and vomiting. The 3rd case refers to a 4 years and 10 months old boy admitted in our clinic with abdominal pain and loss of appetite, who was initially admitted in the Pediatrics Surgery Clinic with the suspicion of appendicitis. Our 4th patient was a 5-year-old boy admitted in our clinic for abdominal pain and intermittent diarrheic stools. DIAGNOSES: In the first case, the laboratory tests showed anemia, thrombocytosis, elevated inflammatory biomarkers, a low level of iron, and hypoproteinemia. The abdominal ultrasound and CT exam revealed an abdominal mass, and the histopathological exam established the diagnosis of diffuse large B-cell lymphoma of the bowel. In the second case, the laboratory tests pointed out anemia, elevated ESR and lactate dehydrogenase level, while both abdominal ultrasound and CT exams showed an abdominal mass. The histopathological exam confirmed the diagnosis of Burkitt lymphoma. Regarding our 3rd case, the laboratory findings revealed leukocytosis, anemia, thrombocytosis, increased inflammatory biomarkers, elevated LDH, and a low level of iron. The abdominal ultrasound and the CT scan revealed an abdominal mass which, according to the histopathological exam, was a Burkitt lymphoma. Due to the cranial CT findings the patient was diagnosed with IV stage Burkitt lymphoma with central nervous system metastases. In our 4th patients we found leukocytosis, anemia, mildly increased inflammatory biomarkers, a high level of LDH, hypoproteinemia, and a low level of serum Ir. Both ultrasound and abdominal CT exams were negative, but the exploratory laparotomy identified an abdominal mass, and according to the histopathological exam the patient was diagnosed with Burkitt lymphoma. INTERVENTIONS: All the patients followed chemotherapy (B-NHL BFM 04 protocol) and supportive treatment. OUTCOMES: The first patient died approximately 4 months after the completion of chemotherapy due to tumor relapse, the second patient died after the first cure of chemotherapy and the fourth patient died at approximately 2 years after the diagnosis. The third patient is recurrence-free after 2 years. LESSONS: Despite the advances in the management, NHL remains a fatal condition in pediatrics.

ABSTRACT

Cancer patients are particularly susceptible to nutritional depletion. From March 2014 to December 2015, we assessed 146 patients consecutively hospitalized in a tertiary emergency pediatric hospital. The patients were divided into 2 groups: group I, patients with cancer (43 patients), and group II, the control group consisting of 103 age-matched and sex-matched healthy patients. The anthropometric parameters (weight-W, height-H, body mass index [BMI], middle upper arm circumference [MUAC], tricipital skinfold thickness [TST]) and biochemical parameters (proteins, albumin) were comparatively evaluated. Fat mass (FM, kg and %), fat-free mass (FFM, kg), muscle mass (MM, kg), and total body water (TBW, %) were measured in both groups using Tanita BC 420 S MA Analyzer. Anthropometric and biochemical parameters in group I were significantly different from those in group II for weight, height, BMI, MUAC, TST, protein, and albumin (P<0.05). In the study group, FM was much lower compared with controls 16.9% (3.4% to 33.3%) versus 20.3% (6.6% to 38.4%); (P=0.001), and TBW was much higher 60.8% (48.8% to 70.6%) versus 58.5% (45.2% to 68.6%) (P=0.004). FFM and MM were not statistically different in the 2 groups. The results highlight the complex changes of nutritional status in pediatric patients with cancer.

ABSTRACT

UNLABELLED: The aim of this study was to analyze insulin-like growth factor I (IGF-I) serum level in pediatric patients with cancer compared with pediatric patients with nononcological diseases and to assess the relationship between IGF-I and nutritional status of oncological patients. From January 2009 to July 2012, we assessed 151 consecutively hospitalized patients in a tertiary emergency pediatric hospital. The patients were divided into two groups: group I, consisting of patients with malignant diseases (64 patients), and group II, the control group, consisting of 87 age- and gender-matched patients with different pediatric diseases. The anthropometric parameters (weight, height, body mass index, middle upper arm circumference (MUAC), and tricipital skinfold thickness (TST) and biochemical parameters (proteins, albumin, and total IGF-I) were comparatively evaluated at the diagnosis and after intensive chemotherapy in the malignant group. Anthropometric and biochemical parameters in group I were significantly different from those in group II for height, MUAC, TST, total proteins, and albumin (p < 0.05). Twenty-five out of 64 patients with malignant diseases and 5 out of 87 patients in the control group had malnutrition. IGF-I in patients with cancer was much lower than in the control group (median 48.3 ng/ml, range 25.00-662.00 ng/ml vs 129.00 ng/ml, range 25.00-745.00 ng/ml) (p = 0.014). We found a positive correlation between IGF-I, MUAC, and TST at the diagnosis of the malignant disease. Also, we identified positive correlations between IGF-I, protein, and albumin. Serum IGF-I levels in cancer patients were significantly lower at diagnosis than after chemotherapy (48.3 ng/ml, range 25.00-662.00 ng/ml vs 110.0 ng/ml, range 25.00-573.00 ng/ml; p = 0.04). CONCLUSION: IGF-I seems to be an accurate biochemical parameter used in malnutrition assessment of children with cancer. IGF-I correlated with the anthropometric parameters of the arm, serum protein, and albumin. These parameters most accurately characterize the nutritional status.
