Primary manifestation of HIV-related Burkitt lymphoma in the oral and maxillofacial regions

BACKGROUND

Burkitt lymphoma (BL) is a subtype of non-Hodgkin lymphoma. It is strongly associated with HIV infection and has a highly aggressive clinical course. The involvement of the maxillofacial region in BL has rarely been reported.

CASE DESCRIPTION

A 36-year-old woman with HIV-positive status had painless bilateral swelling of the oral mucosa and middle and lower thirds of the face. Microscopic analysis of the oral lesion revealed an atypical lymphoid infiltrate with a starry sky pattern. The lymphoid cells expressed cluster of differentiation 20, cluster of differentiation 10, B-cell lymphoma 6, and c-Myc; the Ki-67 proliferative index was high. The tumor cells were positive for Epstein-Barr virus. These results led to the diagnosis of HIV-related BL.

PRACTICAL IMPLICATIONS

BL and other immunodeficiency-related lymphoproliferative malignancies may affect the oral and maxillofacial regions and should be included in the differential diagnosis of rapidly expanding swelling in young patients.

Spontaneous tumor lysis syndrome (STLS) during biopsy for burkitt lymphoma: a case report

BACKGROUND

Tumor lysis syndrome (TLS) is a hematologic oncological emergency characterized by metabolic and electrolyte imbalances. On breakdown of tumor cells, enormous amounts of potassium, phosphate, and nucleic acids are released into systemic circulation. TLS mainly occurs during chemotherapy. However, there are rare incidences of spontaneous tumor lysis syndrome (STLS) prior to commencement of therapy.

CASE PRESENTATION

In the case being reported, the child had just undergone a biopsy. As the incision was being closed, there was a sudden onset of high fever, arrhythmia, severe hyperkalemia, hypocalcemia, and acidosis. Following timely symptomatic treatment and continuous renal replacement therapy(CRRT), the child's laboratory results improved, and organ function was restored to normal. The final pathological diagnosis confirmed Burkitt lymphoma. The boy is currently on maintenance chemotherapy.

CONCLUSIONS

TLS is a potentially life-threatening complication in hematologic oncology. Several important conclusions can be drawn from this case, reminding clinicians to: (1) be fully aware of the risk factors of TLS and evaluate the level of risk; (2) pay attention to the possibility of STLS during operation, if surgical procedures are necessary and operate with minimal trauma and in the shortest time possibly; (3) take preoperative prophylaxis actively for high-risk TLS patients, including aggressive fluid management and rational use of diuretics and uric-acid-lowering drugs. In addition, this case confirms the effectiveness of CRRT for severe STLS.

Botulinum toxin type A improves pain in numb chin syndrome

Numb chin syndrome is a rare pain disorder characterized by decreased sensation and paresthesia in the territory of the mental nerve. Neuropathic pain is sometimes described in this setting, and the most common treatments include oral analgesics, gabapentinoids, and carbamazepine; however, botulinum toxin type A has never been used in this setting. We describe a case of bilateral numb chin syndrome, secondary to Burkitt lymphoma, associated with refractory and persistent burning neuropathic pain, effectively treated twelve times with subcutaneous Botulinum toxin type A (BoNT/A) injections. The procedure was well tolerated, but the patient reported incomplete mouth closure of minimal entity. BoNT/A could be a safe and effective therapy for neuropathic pain associated with numb chin syndrome.

Emergency laparotomy for abdominal catastrophes secondary to lymphoma: A systematic review

Intestinal lymphomas can rarely present as abdominal catastrophes with perforation or small bowel obstruction. There is little data regarding their optimal surgical management and associated outcomes. We aimed to systematically review relevant published literature to assess the presentation, diagnosis, optimal surgical approach and associated post-operative outcomes. A systematic on-line literature search of Embase and Medline identified 1485 articles of which 34 relevant studies were selected, including 7 retrospective studies, 1 case series and 26 case reports. Selected articles were assessed by two reviewers to extract data. 95 patients with abdominal catastrophes secondary to lymphoma (predominately Burkitt (28 %) and Diffuse Large B-cell lymphoma (29 %)) were identified with a median age of 52 years, 40 % were female. Of the small bowel resections 25% (n = 18) suffered post-operative complications with a 13.8 % (n = 10) 30-day mortality. Ileocolonic resections had a 27 % complication rate with 18 % mortality and primary repair had a 25 % complications rate and 25 % mortality. Median follow-up was 8 days (range 1-96). Notable points of differences in the presentations between these different lymphomas included the majority of Burkitt's lymphoma were younger, had a known diagnosis, were on chemotherapy and presented with perforation in contrast to those with B cell lymphoma who were predominately older, had new diagnoses and presented with a balanced proportion of obstruction and perforation. Abdominal catastrophes secondary to intestinal lymphomas most commonly present with perforation. Aggressive surgical management, including small bowel resection, may offer similar remission rates for lymphoma patients presenting with abdominal catastrophes as those without such emergency complications.

Readmission rates in HIV-associated burkitt lymphoma patients in the USA: a nationwide readmission database (NRD) analysis

BACKGROUND

People with human immunodeficiency virus have an increased risk of developing AIDS-defining malignancies including Burkitt lymphoma. Survival outcomes in HIV-associated Burkitt lymphoma remain worse than non-HIV-associated Burkitt lymphoma, despite widespread implementation of antiretroviral therapy. We aimed to determine the association between HIV status and risk for 30-day and 90-day readmission in the US after index hospitalization for Burkitt lymphoma.

METHODS

Data were abstracted from the 2010-2020 Nationwide Readmissions Database; hospitalizations included patients with a primary BL diagnosis and were stratified by comorbid HIV. The primary outcome was all-cause readmission (30-day and 90-day). Secondary outcomes were in-hospital mortality, length of stay (LOS), and hospital cost. Between-HIV differences were evaluated via logistic and log-normal regression; multivariable models adjusted for comorbid kidney disease, hypertension, fluid and electrolyte disorders, and sepsis.

RESULTS

Overall, there were 8,453 hospitalizations for BL and 6.0% carried an HIV diagnosis. Of BL hospitalizations, 68.4% were readmitted within 30-days post index BL hospitalization and 6.8% carried a HIV diagnosis. HIV-associated BL was associated with 43% higher adjusted odds of 30-day readmission (aOR 95% CI: 4% higher to 97% higher, p = 0.026). For 90-day readmission, 76.0% of BL patients were readmitted and 7.0% carried a HIV diagnosis. HIV-associated BL was not statistically associated with all-cause 90-day readmission (aOR 1.46, aOR 95% CI: 0% higher to 115% higher, p = 0.053).

CONCLUSIONS

HIV-positive status is associated with an increased risk for 30-day readmission after index hospitalization for Burkitt lymphoma.

Bone Marrow Aplasia after CAR-T-Cell Therapy for Relapsed/Refractory Burkitt's Lymphoma

Chimeric antigen receptor T-cells (CAR-T) are now a standard approach for treating relapsed/refractory B-cell lymphomas. Immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS) is a newly described entity that can manifest following CAR-T. Bone marrow (BM) aplasia is an uncommon manifestation of IEC-HS reported after CAR-T-cell therapy and is defined as the reduction or absence of hematopoietic progenitor cells resulting in severe pancytopenia. We describe the case of a 44-year-old female with relapsed/refractory Burkitt lymphoma (BL) who received treatment with lisocabtagene maraleucel with her post-CAR-T course complicated by cytokine release syndrome (CRS) and IEC-HS ultimately leading to persistent BM aplasia. She underwent a rescue allogeneic stem cell transplant but ultimately succumbed to progressive disease. IEC-HS is an increasingly recognized complication that occurs after CAR-T treatments that can result in aplasia, a dangerous complication with serious sequelae including infection, transfusion dependence, and high risk for hemorrhage. The underlying mechanism is poorly understood, and further studies are needed to understand how to treat it better.

Burkitt's Thyroid Lymphoma Revealed in a Pregnant Woman With Acute Dyspnea

Extraganglionic Burkitt's lymphoma is rare. Primary thyroid localization accounts for 1% to 5% of malignant tumors of the thyroid gland. The association of Burkitt's lymphoma and pregnancy is even rarer. Our patient was pregnant at 36 weeks. She was brought to the emergency department with anterior cervical swelling, rapidly increasing in volume and becoming compressive for 15 days, in addition to dysphonia and inspiratory dyspnea. Cervical ultrasound and computed tomography scan revealed a compressive and plunging goiter. Surgery attempted after fetal extraction proved impossible due to massive tumor infiltration into adjacent structures shielding the cervical region. Accordingly, the act was limited to a glandular biopsy. The newborn was healthy. Histological examination confirmed the diagnosis of Burkitt's lymphoma. Given the poor general condition of the patient, chemotherapy was not administered and the patient died after 15 days of stay in intensive care unit.

Burkitt's lymphoma in the adult as an unusual cause of large bowel obstruction

Bowel obstruction is an uncommon clinical presentation in Burkitt´s lymphoma, specially in adults. This type of lymphoma is classified within B-cell non-Hodgkin´s lymphomas, which is characterized by its aggressiveness and quickly tumoral growth. The clinical presentation related to the gastrointestinal tract is unusual, but it can be presented as intussusception, obstruction or ischemic perforation. Here we describe a case of Burkitt´s lymphoma with bowel obstruction as a clinical debut.

HLH-like toxicities predict poor survival after the use of tisagenlecleucel in children and young adults with B-ALL

Chimeric antigen receptor-associated hemophagocytic lymphohistiocytosis (HLH)-like toxicities (LTs) involving hyperferritinemia, multiorgan dysfunction, coagulopathy, and/or hemophagocytosis are described as occurring in a subset of patients with cytokine release syndrome (CRS). Case series report poor outcomes for those with B-cell acute lymphoblastic leukemia (B-ALL) who develop HLH-LTs, although larger outcomes analyses of children and young adults (CAYAs) with B-ALL who develop these toxicities after the administration of commercially available tisagenlecleucel are not described. Using a multi-institutional database of 185 CAYAs with B-ALL, we conducted a retrospective cohort study including groups that developed HLH-LTs, high-grade (HG) CRS without HLH-LTs, or no to low-grade (NLG) CRS without HLH-LTs. Primary objectives included characterizing the incidence, outcomes, and preinfusion factors associated with HLH-LTs. Among 185 CAYAs infused with tisagenlecleucel, 26 (14.1%) met the criteria for HLH-LTs. One-year overall survival and relapse-free survival were 25.7% and 4.7%, respectively, in those with HLH-LTs compared with 80.1% and 57.6%, respectively, in those without. In multivariable analysis for death, meeting criteria for HLH-LTs carried a hazard ratio of 4.61 (95% confidence interval, 2.41-8.83), controlling for disease burden, age, and sex. Patients who developed HLH-LTs had higher pretisagenlecleucel disease burden, ferritin, and C-reactive protein levels and lower platelet and absolute neutrophil counts than patients with HG- or NLG-CRS without HLH-LTs. Overall, CAYAs with B-ALL who developed HLH-LTs after tisagenlecleucel experienced high rates of relapse and nonrelapse mortality, indicating the urgent need for further investigations into prevention and optimal management of patients who develop HLH-LTs after tisagenlecleucel.

Tuberculosis combined with Burkitt lymphoma in a kidney transplant recipient: A case report and literature review

RATIONALE

Tuberculosis (TB) and post-transplant lymphoproliferative disorder are serious complications affecting the long-term survival of kidney transplant recipients (KTRs). Both of complications have overlapping clinical symptoms, signs, and high similar imaging presentation, which make early clinical diagnosis challenging. In this paper, we reported a rare case of post-transplant pulmonary TB combined with Burkitt lymphoma (BL) in KTR.

PATIENT CONCERNS

A 20-year-old female KTR presented to our hospital with abdominal pain and multiple nodules throughout the body.

DIAGNOSES

TB is diagnosed based on the lung histopathology showed fibrous connective tissue hyperplasia with number of chronic inflammatory changes, localized necrosis, granuloma formation and multinucleated giant cells were seen in the lung tissue. Moreover, lung histopathology specimen tested positive for TB gene. TB The culture for tuberculosis was positive. BL was diagnosed as metastatic after completion of liver and bone marrow biopsy.

INTERVENTIONS

After an early diagnosis of TB, the patient received intensification of anti-tubercular therapy. Because the patient was diagnosed with BL, rituximab, cardioprotection, hepatoprotection and alkalinization of urine were added.

OUTCOMES

After an early diagnosis of TB, the patient received anti-tubercular therapy and her clinical symptoms and imaging manifestations improved. After the diagnosis of BL was made, the patient's condition progressed rapidly, followed by multi-organ damage and died 3 months later.

LESSONS

Therefore, in organ transplant patients, who present with multiple nodules and normal tumor markers, they should be alerted to the possibility of concurrent TB and post-transplant lymphoproliferative disorder, and perfect tests such as Epstein-Barr virus, β2-microglobulin, lactate dehydrogenase, γ-interferon release test and Xpert Mycobacterium TB/rifampicin test and perform early lesion site biopsy to clarify the diagnosis with a view to improving the prognosis.

Spatial distribution of incident pediatric Burkitt lymphoma in central and northern Malawi and association with malaria prevalence

BACKGROUND

Burkitt lymphoma (BL) accounts for 90% of pediatric lymphomas in sub-Saharan Africa. Plasmodium falciparum malaria is considered an etiological factor of BL. We describe the geographic distribution of pediatric BL in Malawi and association with P. falciparum malaria prevalence rate (PfPR).

METHODS

We enrolled 220 pathologically confirmed incident pediatric BL cases (2013-2018) into an observational clinical cohort at Kamuzu Central Hospital (KCH) in Lilongwe district. KCH is the main tertiary cancer referral center serving the central and northern regions of Malawi. Using an ecological study design, we calculated district-level annual BL incidence rate using census population estimates. District-level PfPR was extracted from the National Malaria Control Program 2010 report. BL incidence and PfPR maps were constructed in QGIS. Moran's I  test was used to identify BL spatial clusters. Pearson's correlation and multiple linear regression analyses were used to statistically examine the relationship between PfPR and BL.

RESULTS

BL incidence was higher in central region districts (8.2 cases per million) than northern districts (2.9 cases per million) and was elevated in lakeshore districts. Districts with elevated PfPR tended to have elevated BL incidence. A low-risk BL cluster was detected in the north. Statistically, BL incidence was positively correlated with PfPR (r = .77, p < .01). A 1% increase in PfPR predicted an increase in BL incidence of 0.2 cases per million (p = .03), when controlling for travel time from referral district hospital to KCH.

CONCLUSION

Our study supports evidence for an association between P. falciparum and BL and highlights a need to improve geographic accessibility to tertiary cancer services in Malawi's northern region.

Impact of Epstein-Barr virus co-infection on natural acquired Plasmodium vivax antibody response

Background

The simultaneous infection of Plasmodium falciparum and Epstein-Barr virus (EBV) could promote the development of the aggressive endemic Burkitt’s Lymphoma (eBL) in children living in P. falciparum holoendemic areas. While it is well-established that eBL is not related to other human malaria parasites, the impact of EBV infection on the generation of human malaria immunity remains largely unexplored. Considering that this highly prevalent herpesvirus establishes a lifelong persistent infection on B-cells with possible influence on malaria immunity, we hypothesized that EBV co-infection could have impact on the naturally acquired antibody responses to P. vivax, the most widespread human malaria parasite.

Methodology/Principal findings

The study design involved three cross-sectional surveys at six-month intervals (baseline, 6 and 12 months) among long-term P. vivax exposed individuals living in the Amazon rainforest. The approach focused on a group of malaria-exposed individuals whose EBV-DNA (amplification of balf-5 gene) was persistently detected in the peripheral blood (PersVDNA, n = 27), and an age-matched malaria-exposed group whose EBV-DNA could never be detected during the follow-up (NegVDNA, n = 29). During the follow-up period, the serological detection of EBV antibodies to lytic/ latent viral antigens showed that IgG antibodies to viral capsid antigen (VCA-p18) were significantly different between groups (PersVDNA > NegVDNA). A panel of blood-stage P. vivax antigens covering a wide range of immunogenicity confirmed that in general PersVDNA group showed low levels of antibodies as compared with NegVDNA. Interestingly, more significant differences were observed to a novel DBPII immunogen, named DEKnull-2, which has been associated with long-term neutralizing antibody response. Differences between groups were less pronounced with blood-stage antigens (such as MSP1-19) whose levels can fluctuate according to malaria transmission.

Conclusions/Significance

In a proof-of-concept study we provide evidence that a persistent detection of EBV-DNA in peripheral blood of adults in a P. vivax semi-immune population may impact the long-term immune response to major malaria vaccine candidates.

[Spinal cord compression secondary to metastasis of gingival Burkitt lymphoma revealing a case of HIV infection in Morocco]

Burkitt lymphoma in HIV-infected patients is seldom seen in the oral cavity, and they are rarely reported in the literature. The clinical manifestations may suggest other tumors or gingival infections, which delays diagnosis and management. Spinal cord involvement is exceptional and only a few cases are reported. We report a case of Burkitt lymphoma in the oral cavity and spinal cord, revealing HIV infection in a 44-year-old patient, who responded well to chemotherapy and antiretroviral treatment and is on remission.

Ruxolitinib reduces severe CRS response by suspending CAR-T cell function instead of damaging CAR-T cells

The therapeutic effect of CAR-T is often accompanied by sCRS, which is the main obstacle to the promotion of CAR-T therapy. The JAK1/2 inhibitor ruxolitinib has recently been confirmed as clinically effective in maintaining control over sCRS, however, its mechanism remains unclear. In this study, we firstly revealed that ruxolitinib significantly inhibited the proliferation of CAR-T cells without damaging viability, and induced an efficacy-favored differentiation phenotype. Second, ruxolitinib reduced the level of cytokine release not only from CAR-T cells, but also from other cells in the immune system. Third, the cytolytic activity of CAR-T cells was restored once the ruxolitinib was removed; however, the cytokines released from the CAR-T cells maintained an inhibited state to some degree. Finally, ruxolitinib significantly reduced the proliferation rate of CAR-T cells in vivo without affecting the therapeutic efficacy after withdrawal at the appropriate dose. We demonstrated pre-clinically that ruxolitinib interferes with both CAR-T cells and the other immune cells that play an important role in triggering sCRS reactions. This work provides useful and important scientific data for clinicians on the question of whether ruxolitinib has an effect on CAR-T cell function loss causing CAR-T treatment failure when applied in the treatment of sCRS, the answer to which is of great clinical significance.

[A Case of Cecal Burkitt's Lymphoma with Intussusception]

We report a case of ileocecal intussusception due to Burkitt's lymphoma(BL). A 14-year-old boy was admitted to our hospital for abdominal pain and diarrhea. He was diagnosed an intussusception by the ultrasonography and the CT scan. Laparoscopic ileocecal resection was performed. A diagnosis of BL was made on basis of pathological examination. He was transferred for the chemotherapy on postoperative day 8. We conclude that, if the intussusception associated with malignant lymphoma is assumed from the preoperative findings, we have to keep minimal surgical invasion and start postoperative chemotherapy immediately.

Primary chest wall Burkitt lymphoma in a case of HIV infection with immune reconstitution

Burkitt lymphoma (BL) develops at an increased frequency in patients with HIV irrespective of the CD4 count. Lymph nodes and gastrointestinal tract are common sites of involvement by BL; however, primary chest wall BL is rare. A 52-year-old man on highly active antiretroviral therapy (HAART) for HIV with a CD4 count of 0.204 x 109 cells/L presented with a 3-month history of enlarging chest wall mass. PET-CT scan imaging showed a bulky mass involving the musculoskeletal planes of left chest wall with the involvement of underlying pleura. Biopsy with immunohistochemistry confirmed BL. Patient received EPOCH-R (infusional etoposide, vincristine, and doxorubicin with prednisone, cyclophosphamide and rituximab) regime for six cycles along with HAART, attained complete remission (CR) and remains free of BL at 5 years. BL should be considered in the differential diagnosis of soft tissue masses in HIV-infected patients irrespective of their CD4 count.

Clinical presentation of gastric Burkitt lymphoma presenting with paraplegia and acute pancreatitis: A case report

BACKGROUND

The incidence of gastric Burkitt lymphoma (BL), presenting as paraplegia and acute pancreatitis, is extremely low. BL is a great masquerader that presents in varied forms and in atypical locations, and it is prone to misdiagnosis and missed diagnosis. The prognosis of BL remains poor because of the difficulty in early diagnosis and the limited advances in chemotherapy.

CASE SUMMARY

A 53-year-old man was referred to our hospital from the local county hospital due to abdominal pain for two weeks and weakness in the lower extremities for one day. Magnetic resonance imaging of the abdomen and lumbar spine showed a swollen pancreas and gallbladder, with peripancreatic exudation and liquid collection, indicating acute pancreatitis and acute cholecystitis. Additionally, we observed abnormally thickened lesions of the gastric wall, multiple enlarged retroperitoneal lymph nodes and a well-demarcated, posterolateral extradural mass lesion between T9 and T12, with extension through the spinal foramen and definite bony destruction, suggesting metastasis in gastric malignancy. Subsequent whole-body positron emission tomography/computed tomography examination showed multifocal malignant lesions in the stomach, pancreas, gallbladder, bone, bilateral supraclavicular fossa, anterior mediastinum, bilateral axillary and retroperitoneal lymph nodes. Gastroduodenal endoscopy revealed primary BL with massive involvement of the gastric body and duodenum. The patient refused chemotherapeutic treatment and died one week later due to upper gastrointestinal hemorrhage. Afterward, we reviewed the characteristics of 11 patients with BL involving the stomach, pancreas or spinal cord.

CONCLUSION

Clinicians should be aware that BL can be the potential cause of acute pancreatitis or a rapidly progressive spinal tumor with accompanying paraplegia. For gastric BL, gastroscopy biopsies and pathology are necessary for a definite diagnosis.

Bacterial Infection and Non-Hodgkin B-Cell Lymphoma: Interactions between Pathogen, Host and the Tumor Environment

Non-Hodgkin B-cell lymphomas (NHL) are a heterogeneous group of lymphoid neoplasms with complex etiopathology, rich symptomatology, and a variety of clinical courses, therefore requiring different therapeutic approaches. The hypothesis that an infectious agent may initiate chronic inflammation and facilitate B lymphocyte transformation and lymphogenesis has been raised in recent years. Viruses, like EBV, HTLV-1, HIV, HCV and parasites, like Plasmodium falciparum, have been linked to the development of lymphomas. The association of chronic Helicobacter pylori (H. pylori) infection with mucosa-associated lymphoid tissue (MALT) lymphoma, Borrelia burgdorferi with cutaneous MALT lymphoma and Chlamydophila psittaci with ocular adnexal MALT lymphoma is well documented. Recent studies have indicated that other infectious agents may also be relevant in B-cell lymphogenesis such as Coxiella burnettii, Campylobacter jejuni, Achromobacter xylosoxidans, and Escherichia coli. The aim of the present review is to provide a summary of the current literature on infectious bacterial agents associated with B-cell NHL and to discuss its role in lymphogenesis, taking into account the interaction between infectious agents, host factors, and the tumor environment.

Burkitt lymphoma of the nasopharynx causing life-threatening airway obstruction: A case report

OBJECTIVE

To describe a case of Burkitt lymphoma (BL) in a child manifesting with acute airway obstruction. To review available literature on the clinical features and characteristic presentation of this disease.

METHODS

Case report with literature review.

RESULTS

We present the case of an 8-year-old boy with nasopharyngeal BL manifesting initially as sore throat, nasal congestion, and snoring that progressed to dyspnea and, ultimately, acute airway obstruction requiring emergent tracheostomy. The child was treated with intensive chemotherapy and achieved complete response.

CONCLUSION

This case highlights the importance of maintaining high clinical suspicion when evaluating common otolaryngologic symptoms and emphasizes the potential for Burkitt lymphoma to cause rapid patient deterioration.

Comparison between children and adults intussusception. Description of two cases and review of literature

INTRODUCTION

Intussusception is a common condition in children, it is rare in adults. Adult intussusception differs from pediatric intussusception in various respects, including etiology clinical characteristics and therapy.

METHODS

We present and discuss a new case of intussusception in children and adults.

RESULTS

In child the Barium Enema x-ray examination is identified an endoluminal filling defect to refer to the apex of the invaginated loop at the rectal level, with slow ascent during the progressive injection of the radiopaque contrast medium. At the end of the procedure, incomplete reduction of the picture is documented. The patient undergoes emergency surgery where the presence of an ileo-ceco-colic invagination is documented. Intussusception is reduced by taxis. In the adult laparoscopic right hemicolectomy was performed. High-grade B-cell Burkitt's lymphoma was confirmed by immunohistochemistry.

DISCUSSION

In contrast to intussusceptions in children, in the adult population, a demonstrable etiology is found in most of the cases. In adults surgery is always indicated. The non-invasive resolutive intervention most commonly used in the child and best known consists in the rectal introduction of a radiopaque contrast medium (air or barium) at controlled pressure until.

CONCLUSIONS

Although intussusceptions occur at all ages, there are major differences in the clinical presentation, diagnostic approach, and management between pediatric and adult populations. Intussusception is remarkably different in these two age groups and it must be approached from a different clinical perspective.

KEY WORDS

Intussusception in children, Intussusception in adults, Intussusception symptoms, Radiology and treatment.

Burkitt lymphoma associated with human immunodeficiency virus infection and pulmonary tuberculosis: A case report

INTRODUCTION

The association of human immunodeficiency virus (HIV) infection with Burkitt lymphoma is related to the presence of Epstein Barr virus infection and the impact of the HIV antigen on the expansion of B-polyclonal cells. In Southeast Europe, the association is rare, and recognizing this is important in the therapeutic decision to increase patient survival rate. The association of HIV with Burkitt lymphoma and tuberculosis is even more rarely described in the literature.

PATIENT CONCERNS

We present the case of a 40-year-old patient who presented with a 3-week history of fever (max. 38.7 °C), painful axillary swelling on the right side, lumbar pain, gait disorders, headache, and night sweats. Clinical manifestations included marked weight loss (about 30 kg in the last 2 months before his admission).

DIAGNOSIS

A LyCD4 count of 38/μL and a HIV1 viral load of 384,000/mm3, classified the patient into a C3 stage. A biopsy of the right axillary lymph node was performed for suspected ganglionic tuberculosis due to immunodeficiency. Histopathological examination confirmed the diagnosis of Burkitt lymphoma. Cultures on Löwenstein-Jensen medium from sputum harvested at first admission were positive for Mycobacterium tuberculosis.

INTERVENTIONS

Highly active antiretroviral therapy, chemotherapeutic agents for Burkitt lymphoma, anti-tuberculous drug therapy, neurosurgical intervention of spinal cord decompression, and antibiotic therapy of the associated bacterial infection.

OUTCOME

Burkitt lymphoma disseminated rapidly, with central nervous system, spinal cord, osteomuscular, adrenal, and spleen involvement. The evolution under treatment was unfavorable, with patient death occurring 6 months after diagnosis.

CONCLUSIONS

The association of HIV infection with Burkitt lymphoma and tuberculosis is rare in the highly active antiretroviral therapy (HAART) era, posing prompt and multidisciplinary therapeutic management issues. Similar cases of HIV-TB and Burkitt lymphoma association have been described, but none of the other cases showed the involvement of the central nervous system or of the bilateral adrenal glands.

Stable Incidence and Poor Survival for HIV-Related Burkitt Lymphoma Among the US Veteran Population During the Antiretroviral Era

BACKGROUND

Despite advances in diagnosis and treatment of both HIV and Burkitt lymphoma (BL), persons living with HIV remain at high risk for BL. We conducted this study to evaluate if there have been any changes in the risk of or survival after BL diagnosis among persons living with HIV during the antiretroviral era.

SETTING

Veterans living with HIV (VLWH) and age-matched HIV-negative controls receiving care between 1999 and 2016 were retrospectively identified using Veterans Health Administration electronic medical records.

METHODS

We identified BL diagnoses through Veterans Health Administration Cancer Registry review and International Classification of Diseases, Ninth/Tenth Revisions, codes, and we extracted demographic, lifestyle, and clinical variables from electronic medical record. We estimated hazard ratios (HR) and 95% confidence intervals (CIs) for BL risk and survival using Cox proportional models.

RESULTS

We identified 45,299 VLWH. Eighty-four developed BL (incidence rate = 21.2 per 100,000 person years; CI: 17.1 to 26.3). Median CD4 count at BL diagnosis was 238 cells per milliliter (SD: 324.74) and increased over time. Survival was truncated in VLWH with BL (P < 0.05). The risk of BL in VLWH was 38% less in blacks compared with whites (HR: 0.620; CI: 0.393 to 0.979; P = 0.0401). VLWH with an undetectable viral load for at least 40% of follow-up were 74% less likely to develop BL (HR: 0.261; CI: 0.143 to 0.478; P < 0.0001) and 86% less likely to die after diagnosis (HR: 0.141; CI: 0.058 to 0.348; P < 0.0001).

CONCLUSIONS

BL incidence among VLWH did not improve between 2000 and 2016. Survival after BL diagnosis in VLWH remains dismal as compared with their HIV-negative counterparts, although veterans with prolonged periods of undetectable viral load had improved prognosis.

Autologous hematopoietic stem cell transplantation for human immunodeficiency virus associated gastric Burkitt lymphoma: A case report

RATIONALE

HIV-related lymphoma, especially non-Hodgkin lymphoma, is one of the most common malignant tumors in HIV/acquired immune deficiency syndrome (AIDS) patients. Autologous hematopoietic stem cell transplantation (AHSCT) for the patients with Burkitt lymphoma (BL) is needed to be further explored.

PATIENT CONCERNS

A 57-year-old man was hospitalized with intermittent pain on upper abdomen and melena for >1 month.

DIAGNOSIS

HIV antibody testing was positive. The upper gastrointestinal endoscopy was performed and histopathology and immunohistochemistry revealed BL.

INTERVENTIONS

Highly effective antiretroviral therapy and sixth cycles of chemotherapy were administered, followed by autologous hematopoietic stem cell transplantation.

OUTCOMES

The patient has had tumor-free survival for >6 years with normal CD4+ T cell counts and HIV viral load below the lowest detection LESSONS:: The patient was treated with AHSCT followed complete remission after chemotherapy and achieved long-term disease-free survival. AHSCT may be a promising way for clinical cure of HIV-related BL.

Concurrent lymphoma and hemophilia B in a pediatric patient: A case report

INTRODUCTION

Lymphoma is the third most common cancer among children in the United States and Europe. Hemophilia is a congenital bleeding disorder characterized by deficiency of coagulation factor VIII or IX. Hemophilia B is a consequence of factor IX deficiency and has an incidence of 1 in 20,000 male births. A concurrence of these 2 uncommon diseases is rare except in patients infected with the human immunodeficiency virus (HIV). We report a case of a patient with both Burkitt lymphoma and hemophilia B; this is only such report in China since 1987.

PATIENT CONCERNS

A 3-year-old boy was admitted to our hospital because of melena and jaundice for several days. His older brother had died due to hemophilia B and ventricular septal defect. The patient had not experienced any previous episodes of severe bleeding. Gradual abdominal distention was observed after admission; the patient's superficial lymph nodes were not enlarged. Results of blood routine and bone marrow examinations showed no abnormalities. He was diagnosed with sclerosing cholangitis, abdominal infection, and hepatitis. However, after treatment of reducing enzyme activity and eliminating jaundice, the patient's condition deteriorated. Hydrops abdominis was detected on abdominal ultrasonography. Tumor cells were found by pathological examination of peritoneal effusion. Both a c-myc gene translocation and a c-myc-IgH gene fusion were detected.

DIAGNOSIS

Burkitt lymphoma and hemophilia B.

INTERVENTIONS

The patient was transferred to the Pediatric Hematology Department of our hospital and treated with a modified B-NHL-BFM-95 protocol. During chemotherapy, platelet changes were monitored regularly and blood products were infused timely.

OUTCOMES

The patient died of infection and bleeding after chemotherapy.

CONCLUSION

Concurrent hemophilia and lymphoma are rare, especially in children. When encountering a patient with unexplained obstructive jaundice and massive ascites, the possibility of a tumor should be considered. Early diagnosis and adequate treatment of such tumor may improve prognosis.

Paediatric burkitt lymphoma presenting as a mandible swelling and intussusception

Burkitt lymphoma is a rare entity especially in this part of the world. We had an 11-year-old patient presented with swelling of the mandible for a short one-month duration. He was planned for excision biopsy. However developed severe abdominal pain while in the hospital and was diagnosed as intussusception after ultrasound was done. We proceeded with right hemicolectomy and excision of buccal mass. Early recognition and close monitoring of insidious jaw lesions is recommended even in young adults not within the modal age category of endemic Burkitt.

Sporadic Burkitt's lymphoma masquerading as an intussuscepted Meckel's diverticulum in a 9-year-old child

We report the case of a 9-year-old boy who presented with abdominal pain and was found to have an intussusception with a sporadic Burkitt's lymphoma (BL) lead point. Our case was unusual in that the patient did not present with the typical clinical features of BL, nor was he in a high-risk demographic for this uncommon disease.

Evaluating the Causal Link Between Malaria Infection and Endemic Burkitt Lymphoma in Northern Uganda: A Mendelian Randomization Study

Background

Plasmodium falciparum (Pf) malaria infection is suspected to cause endemic Burkitt Lymphoma (eBL), but the evidence remains unsettled. An inverse relationship between sickle cell trait (SCT) and eBL, which supports that between malaria and eBL, has been reported before, but in small studies with low power. We investigated this hypothesis in children in a population-based study in northern Uganda using Mendelian Randomization.

Methods

Malaria-related polymorphisms (SCT, IL10, IL1A, CD36, SEMA3C, and IFNAR1) were genotyped in 202 eBL cases and 624 controls enrolled during 2010–2015. We modeled associations between genotypes and eBL or malaria using logistic regression.

Findings

SCT was associated with decreased risk of eBL (adjusted odds ratio [OR] 0·37, 95% CI 0·21–0·66; p = 0·0003). Decreased risk of eBL was associated with IL10 rs1800896-CT (OR 0·73, 95% CI 0·50–1·07) and -CC genotypes (OR 0·53, 95% CI 0·29–0·95, p_trend = 0·019); IL1A rs2856838-AG (OR 0·56, 95% CI 0·39–0·81) and -AA genotype (OR 0·50, 95% CI 0·28–1·01, p_trend = 0·0016); and SEMA3C rs4461841-CT or -CC genotypes (OR 0·57, 95% CI 0·35–0·93, p = 0·0193). SCT and IL10 rs1800896, IL1A rs2856838, but not SEMA3C rs4461841, polymorphisms were associated with decreased risk of malaria in the controls.

Interpretation

Our results support a causal effect of malaria infection on eBL.

•

Mendelian randomization analysis was done to assess a causal relationship between malaria infection and endemic Burkitt lymphoma in Uganda

•

Carriage of the sickle cell trait was associated with decreased risk of endemic Burkitt lymphoma

•

Heterozygous or homozygous minor alleles of IL10 rs1800896, IL1A rs2856838, and SEMA3C rs4461841 were associated with decreased risk of endemic Burkitt lymphoma

•

The inverse association between sickle cell trait and endemic Burkitt lymphoma supports a causal role of malaria in endemic Burkitt lymphoma

Malaria, Epstein-Barr virus infection and the pathogenesis of Burkitt's lymphoma

A geographical and causal connection has long been recognized between malaria, Epstein-Barr virus (EBV) infection and Burkitt's lymphoma (BL), but the underlying mechanisms remain obscure. Potential clues are that the malaria parasite Plasmodium falciparum selectively absorbs vitamin A from the host and depends on it for its biological activities; secondly, alterations in vitamin A (retinoid) metabolism have been implicated in many forms of cancer, including BL. The first author has proposed that the merozoite-stage malaria parasite, emerging from the liver, uses its absorbed vitamin A as a cell membrane destabilizer to invade the red blood cells, causing anemia and other signs and symptoms of the disease as manifestations of an endogenous form of hypervitaminosis A (Mawson AR, Path Global Health 2013;107(3):122-9). Repeated episodes of malaria would therefore be expected to expose the tissues of affected individuals to potentially toxic doses of vitamin A. It is proposed that such episodes activate latent EBV infection, which in turn activates retinoid-responsive genes. Expression of these genes enhances viral replication and induces germinal center (GC) B cell expansion, activation-induced cytidine deaminase (AID) expression, and c-myc translocation, which in turn predisposes to BL. Thus, an endogenous form of retinoid toxicity related to malaria infection may be the common factor linking frequent malaria, EBV infection and BL, whereby prolonged exposure of lymphatic tissues to high concentrations of retinoids may combine to induce B-cell translocation and increase the risk of Burkitt's lymphoma.

Silent presentation of multiple metastasis Burkitt lymphoma in a child: A case report and review of the literature

RATIONALE

The Burkitt lymphoma (BL) is a very aggressive B-cell non-Hodgkin's lymphoma. It accounts for 34% of lymphoma cases in children.

PATIENT CONCERNS

We present the case of a 6-year-old boy diagnosed with BL, who presented multiple contrasting elements of the disease: silent symptomatology, without involvement of the bone marrow at first, but with multiorgan infiltration and a fast evolution, despite starting the treatment shortly after the symptoms appeared.

DIAGNOSES

He was diagnosed with BL after immunophenotyping from the pleural fluid.

INTERVENTIONS

After a week from admission, chemotherapy was initiated according to protocol NH-BFM therapeutic group III-cytoreductive phase in the acute care ward and subsequently the AA 24 treatment.

OUTCOMES

Following the treatment, the patient developed medullary aplasia and cutaneous toxicity. The patient's general state remained severe during the hospitalization.

LESSONS

Even though the prognosis of BL has improved over time (up to 90% survival rate), in this case the evolution was unfavorable. In our patient, the symptoms appeared abruptly. They appeared late in the phase of multiple-organ dissemination, which generated the pessimistic prognosis.

Pancreas Burkitt primary lymphoma in pediatric age

We present an the case of an eight-year-old Portuguese boy with no history of traveling, admitted with non-specific abdominal pain. An analytic study revealed high levels of lipase and amylase. Ultrasound, abdominal computerized tomography (CT), and an abdominal magnetic resonance imaging (MRI), were performed. The imaging findings are suggestive of a pancreatic tumor which is an extremely rare entity in children. A biopsy was performed by opened surgery and identified a Burkitt lymphoma.

Burkitt lymphoma as a lead point for jejunojejunal intussusception in a human immunodeficiency virus patient

Intussusception is commonly seen in children but is rare in adults and represents only 5% of all intussusceptions causing 1% of intestinal obstructions. More than 50% of these intussusceptions in adults are due to intestinal neoplasms, including malignant lymphoma, e.g., Burkitt lymphoma. These lymphomas are more common in human immunodeficiency virus (HIV)-positive patients than in the general population. We present a case of a young male who was diagnosed with HIV when he developed intestinal obstruction and intussusception secondary to Burkitt lymphoma. He was managed with surgical resection followed by chemotherapy and antiretroviral treatment. HIV patients presenting with acute abdomen pose a diagnostic challenge to clinicians due to a wide range of differential diagnoses including inflammatory, infectious and neoplastic conditions. In a young HIV patient presenting with acute abdomen, intussusception caused by Burkitt lymphoma should be considered in the differential.

Proptosis as initial manifestation of Burkitt's lymphoma with orbital involvement

CASE PRESENTATION

A 35-year-old woman without any known systemic disorder presented with a complaint of painful and rapidly increasing proptosis in her right eye. Based on the clinical, radiological, analytical and ophthalmological assessments, the diagnosis made was Burkitt's lymphoma in acquired immunodeficiency syndrome.

CONCLUSION

Proptosis can be an unusual way of presenting with Burkitt's lymphoma associated with acquired immunodeficiency. This differential diagnosis is important because confirmation leads to a change in the vital prognosis of the patient.

Two Cases of Neurolymphomatosis with Fatal Bilateral Vocal Cord Paralysis that were Diagnosed with 18F-fluorodeoxyglucose Positron Emission Tomography (FDG PET)/CT

Neurolymphomatosis is a rare entity defined as nerve infiltration by neurotropic abnormal lymphocytes which can lead to the development of neuropathy, with typical presentations including pain, hypoesthesia, paresthesis and palsy. We herein report two cases where critical bilateral vocal cord paralysis due to neurolymphomatosis in recurrent nerves occurred in refractory Burkitt lymphoma and adult T-cell lymphoma patients. High-dose methotrexate and intrathecal chemotherapy injection for the nervous lesions were ineffective, and the patients died. Neurolymphomatosis of the recurrent nerve is an emergent and difficult complication and should be suspected when sudden onset of aphasia, hoarseness or shortness of breath is found in refractory lymphoma patients.

Laryngotracheal mucormycosis: Report of a case

Airway mucormycosis is a deadly opportunistic infection that affects immunocompromised persons, particularly diabetics and those undergoing chemotherapy. Although it is typically a pulmonary or sinonasal infection, mucormycosis can affect the larynx and trachea, with devastating results. We report the case of a 46-year-old man with human immunodeficiency virus infection, hepatitis C infection, neurosyphilis, and recently diagnosed Burkitt lymphoma who presented with dysphonia and stridor after receiving one dose of intrathecal chemotherapy. Flexible laryngoscopy detected the presence of fibrinous material that was obstructing nearly the entire glottis. Surgical debridement revealed a firm mucosal attachment; there was little bleeding when it was removed. After debridement, the patient's dyspnea improved only to recur 2 days later. After an awake tracheotomy, laryngoscopy and bronchoscopy identified necrosis extending from the supraglottic area to the carina tracheae. Biopsies demonstrated hyphal architecture consistent with mucormycosis. Despite continued debridements, the fibrinous material reaccumulated. The patient was placed in hospice care; his airway remained patent, but he died from other causes several weeks after presentation. The management of airway mucormycosis is challenging and complex. Fungal airway infections should be considered in the differential diagnosis of an immunosuppressed patient who presents with dyspnea, dysphonia, and vocal fold immobility. Timely diagnosis and management are critical for a successful outcome, although the prognosis is poor if the infection is widespread, even with the best of efforts.

Burkitt’s Lymphoma: Thorax to Pelvis

Burkitt’s lymphoma is a sub-group of non-Hodgkin’s lymphoma of high-grade with an aggressive clinical course and is composed of diffuse, small and non-cleaved, undifferentiated malignant cells of lymphoid origin. Dennis Burkitt first described this entity in 1956 in equatorial Africa. It is one of the fastest growing cancers in humans with a growth fraction close to 100%. It commonly occurs in children and young adults, with frequent involvement of bone marrow and central nervous system. These are considered to be medical emergencies and require immediate diagnostic and therapeutic intervention. In this report, we present a case of Burkitt’s lymphoma with unusual presentation with the involvement of both thorax and the whole of the abdomen.

Burkitt Lymphoma Preceded by Autoimmune Hemolytic Anemia due to Anti-D Antibody

We herein report a rare case of Burkitt lymphoma (BL) preceded by autoimmune hemolytic anemia (AIHA) caused by autoantibodies against D antigen. After a partial response to AIHA with prednisolone (PSL) treatment for 7 months, the patient developed BL with a t(8;22)(q24;q11.2) chromosomal translocation. Intensive immunochemotherapy, including rituximab, led to a complete response (CR) of BL; however, anti-D antibody remained detectable in the plasma and antibody-dissociated solution from erythrocytes, thus continuous therapy with PSL was necessary even after achievement of the CR. BL with AIHA is extremely rare, with only one previously reported case in the literature.

Can Burkitt's Lymphoma and Hodgkin's Lymphoma occur in siblings simultaneously?

Familial clustering of Hodgkin lymphoma (HL) and increased risk of developing disease among the siblings has been reported earlier. Usually familial lymphoma in sibling pairs occurs in the pairs of either non-Hodgkin lymphoma or HL. In the familial HL, same type of human leukocyte antigens (HLA) is responsible in the affected family members. There are also some studies stating "Killer cell immunoglobulin like receptor (KIR)" genotypes can be important in the etiology of familial HL. Here we report two siblings; one with Non-Hodgkin and the other with Hodgkin lymphoma which showed Epstein-Barr virus encoded small RNAs positivity in the tumor tissues. We have also found that their HLA genotypes are same with each other. In addition, we have discussed familial lymphoma pathogenesis and HLA haplotypes.

Epstein-Barr virus genetic variation in lymphoblastoid cell lines derived from Kenyan pediatric population

Epstein-Barr virus (EBV) is associated with Burkitt’s lymphoma (BL), and in regions of sub-Saharan Africa where endemic BL is common, both the EBV Type 1 (EBV-1) and EBV Type 2 strains (EBV-2) are found. Little is known about genetic variation of EBV strains in areas of sub-Saharan Africa. In the present study, spontaneous lymphoblastoid cell lines (LCLs) were generated from samples obtained from Kenya. Polymerase chain reaction (PCR) amplification of the EBV genome was done using multiple primers and sequenced by next-generation sequencing (NGS). Phylogenetic analyses against the published EBV-1 and EBV-2 strains indicated that one sample, LCL10 was closely related to EBV-2, while the remaining 3 LCL samples were more closely related to EBV-1. Moreover, single nucleotide polymorphism (SNP) analyses showed clustering of LCL variants. We further show by analysis of EBNA-1, BLLF1, BPLF1, and BRRF2 that latent genes are less conserved than lytic genes in these LCLs from a single geographic region. In this study we have shown that NGS is highly useful for deciphering detailed inter and intra-variations in EBV genomes and that within a geographic region different EBV genetic variations can co-exist, the implications of which warrant further investigation. The findings will enhance our understanding of potential pathogenic variants critical to the development and maintenance of EBV-associated malignancies.

Glomerular lesions in malignancies

Glomerular lesions have been recognized in nearly all forms of malignant diseases. The incidence within each category of malignancy varies substantially but in most series represents less than 2% of the population. While there is a considerable variety of glomerular lesions, a number of general statements may be made. In Hodgkin's disease and other lymphomas, the most common lesion is minimal lesion nephrotic syndrome, reflecting possibly an anomaly of T cell function. Amyloidosis which used to be the commonest lesion has nearly disappeared. On the other hand, in patients with chronic lymphocytic leukemia a large proportion of glomerular lesions fall into the category of proliferative glomerulonephritis. In carcinoma the vast majority of glomerular lesions with proteinuria or the nephrotic syndrome are due to membranous glomerulonephritis. This suggests either a local alteration of fixed glomerular antigens, or localization of tumor antigens planted in the glomeruli leading to the formation of local immunocomplexes. Amyloid AA is still frequent in carcinoma and complicates as much as 3% of renal adenocarcinomas.
