Esclerosis bilateral de huesos largos: enfermedad de Erdheim-Chester. Reporte de un caso / Bilateral long bone sclerosis: Erdheim-Chester disease. Case report

La enfermedad de Erdheim-Chester (EEC) es una patología poco frecuente, caracterizada por presentar infiltración xantogranulomatosa sistémica, con afección de diversos sistemas incluido el óseo. La EEC se encuentra descripta dentro de las enfermedades osteocon-densantes (EO), las cuales se reconocen por presentar aumento de la masa ósea y compromiso tanto de huesos largos como planos. La presentación clínica de la EEC es variada: puede presentar desde un curso indolente hasta manifestaciones multisistémicas. Las características radiológicas son de gran importancia para establecer su diagnóstico. Presentamos una paciente con EEC, con esclerosis bilateral de huesos largos, que exhibe algunas características diferenciales con relación a otros casos reportados: a) afectación exclusivamente ósea a 10 años de evolución, b) compromiso bilateral y simétrico de distinta magnitud, c) esclerosis cortical endóstica y perióstica, d) signos radiológicos sugestivos de periostitis, d) ausencia de compromiso metafisario, e) ausencia de actividad metabólica de las lesiones en las imágenes de 18F-FDG PET/CT.Conclusión: la presencia de lesiones osteocondensantes bilaterales exclusivamente en huesos largos deben hacer sospechar EEC. La ausencia de compromiso metafisario y de actividad metabólica en 18F-FDG PET/CT ha sido raramente descripta. (AU)

Erdheim - Chester disease (ECD) is a rare disease, characterized by systemic xanthogranulomatous infiltration, with involvement of various organs including bone. ECD is described within the sclerosing bone disorders, which are recognized for presenting increased bone mass and involvement of both long and flat bones. The clinical presentation of ECD is diverse, ranging from an asymptomatic course to multisystemic manifestations. Radiological features are of great importance to establish the diagnosis. We describe here a patient with ECD, with bilateral sclerosis of long bones that presents some differential characteristics in relation to other reported cases: a) exclusively bone involvement at 10 years of evolution, b) bilateral and symmetric involvement of different magnitude, c) endosteal and periosteal cortical sclerosis d) radiological signs suggestive of periostitis, d) absence of metaphyseal involvement, e) absence of metabolic activity of the lesions in 18F-FDG PET/CT.Conclusion: the presence of bilateral osteosclerosis exclusively in long bones should lead to suspect ECD. The absence of metaphyseal involvement and metabolic activity in 18F-FDG PET/CT have been rarely described. (AU)

Pathological characteristics and clinical prognosis of nodular sclerosis grade 2 of classic Hodgkin's lymphoma / 中华肿瘤杂志

Objective: To investigate the pathological characteristics and clinical prognosis of nodular sclerosis grade 2 of classic Hodgkin's lymphoma (cHL-NS2) in our cancer center. Methods: A retrospective collection of 23 cases of cHL-NS2 admitted in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from July 2008 to April 2019 was performed. Fifty-five cases of nodular sclerosis grade 1 of classical Hodgkin's lymphoma (cHL-NS1) during the same period were selected as control group. Survival curves were plotted using the Kaplan-Meier method, and Cox regression model was used to analyze the influencing factors for survival. Results: The median age of 23 cases of cHL-NS2 was 30 years old. Five cases had extra nodal invasion, and 19 cases were Ⅰ-Ⅱ stage based on Ann Arbor system. The pathological morphology of cHL-NS2 showed that the lymph node structure was completely destroyed and was divided into nodules by thick collagen. The tumor cells in the nodules were abundant and proliferated in sheets. The boundaries between the tumor cells were not clear. The incidence of tumor necrosis in cHL-NS2 was 43.5% (10/23), which was significantly higher than 18.2% (10/55) in cHL-NS1 (P=0.040). The 3-year progression-free survival (PFS) rate of patients in the cHL-NS2 group was 58.1%, which was significantly lower than 89.7% in the cHL-NS1 group (P=0.002). In all of 78 cases, the 3-year PFS rate of patients who did not obtain complete response (CR) was 67.1%, which was significantly lower than 92.2% in patients who achieved CR (P=0.030). Multivariate Cox regression analysis demonstrated that both cHL-NS2 and failure to obtain CR by first-line treatment were independent indicators for short PFS time (P<0.05). Conclusions: In cHL-NS2, the morphology of tumor cells are diverse, and tumor necrosis can be easily found. Under the current first-line treatments of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP), cHL-NS2 is an independent indicator for worse PFS.

Evaluación del tratamiento de linfoma de Hodgkin con esquema ABVD en Chile / Treatment of Hodgkin lymphoma: analysis of 915 patients

Background: Hodgkin lymphoma has a high rate of curability, even in advanced stages. Aim: To assess the results of Hodgkin lymphoma treatment using the ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) chemotherapy regimen. Material and Methods: Analysis of a database held by the Chilean Ministry of Health, including all patients treated at accredited cancer treatment centers. Results: Data for 915 patients, median age 35 years (range 15-86 years) and followed for a median of 97 months (range 1-347 months) were analyzed. Forty-one percent had localized disease. Overall survival at five years for localized and advanced stages was 92% and 74%, respectively. The figures for progression free survival were 87% and 64%, respectively. Patients with relapse who received autologous stem cell transplantation (ASCT) had a five year overall survival of 92%, compared to 64% among those who did not undergo this procedure (p < 0.01). The Guarantees in Health Program set up by the Ministry of Health, was associated with earlier stage disease at diagnosis. Conclusions: The ABVD regimen achieves high rates of cure in localized stages of the disease but the results in advanced stages are not optimal. ASCT significantly improves survival in patients with relapse. The Guarantees in Health Program is associated with earlier diagnosis of the disease.

Acquired Reactive Perforating Collagenosis as a Preceding Manifestation of Hodgkin's Lymphoma / 대한피부과학회지

A 40-year-old man presented with pruritic, multiple, variable-sized, erythematous umbilicated papules on the trunk and both extremities for 4 months. He was diagnosed with Hodgkin's lymphoma (stage IIA) after histopathologic examination of a neck mass that developed a month ago. A punch biopsy was performed on his right lower leg. Histological examination showed transepidermal elimination of the degenerated collagen. Masson's trichrome staining was performed to distinguish collagen fibers from the muscular tissue; using Masson's stain, the collagen appeared as a bluish color crossing from the dermis to the epidermis. The diagnosis of acquired reactive perforating collagenosis was made. The skin lesions showed much improvement after 6 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy. Acquired perforating disorders are a group of cutaneous disorders that occur in adults with chronic kidney disease or diabetes mellitus. Cases of acquired perforating disorders associated with Hodgkin's lymphoma have been rarely reported in the English literature. To our knowledge, this is the first case of acquired reactive perforating collagenosis in a Korean patient with Hodgkin's lymphoma.

A Case of Recurrent Rosai-Dorfman Disease Successfully Treated with 2-Chlorodeoxyadenosine (Cladribine) / 임상소아혈액종양

Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease (RDD), is a rare histiocytic disorder of unknown etiology. Most patients with RDD have spontaneous remission, but in some patients, the disease recurs after complete remission and may not respond to general treatment. Some patients with RDD involving the extranodal system can have serious symptoms such as vital organ dysfunction due to mass effects, neurological symptoms caused by intracranial involvement, and respiratory distress with airway involvement. We report the case of a 7-year-old girl with severe dyspnea due to refractory extranodal RDD that caused progressive upper airway obstruction. She was admitted because of nasal congestion and persistent cervical lymphadenopathy, and diagnosed as having RDD by cervical lymph node incisional biopsy. The initial prednisone treatment did not improve her symptoms. The following contrast-enhanced neck computed tomography revealed a newly developed airway mass protruding in the upper trachea. After 8 weeks of chemotherapy with vinblastine, methotrexate, and prednisone, complete remission was attained. Seven months after chemotherapy cessation, the disease recurred, and chemotherapy with vincristine, cytarabine, and prednisone was resumed. Despite the chemotherapy and emergency radiotherapy, no improvement was observed in the cervical lymph node enlargement and airway obstructive symptom due to the upper tracheal mass. 2-Chlorodeoxyadenosine (cladribine) therapy was initiated, and the patient got complete remission after 6 cycles of the cladribine treatment and maintained no evidence of disease for 2 years. We suggest that cladribine is an effective treatment option for recurrent/refractory RDD.

Necrolisis epidérmica tóxica en el curso de un síndrome hemofagocítico secundario a linfoma de Hodgkin: caso clínico / Toxic epidermal necrolysis during a hemophagocytic syndrome secondary to Hodgkin lymphoma: report of one case

Toxic epidermal necrolysis (TEN) is a lethal entity, characterized by extensive epidermal necrosis and multiorgan failure. Hemophagocytic syndrome (HFS) is also a rare and lethal syndrome characterized by hyperinflammation that leads to the appearance of fever, pancytopenia, organomegaly and hemophagocytosis. The concomitance of these diseases is extremely uncommon. We report a 38 years old female, who during the course of a HFS secondary to Hodgkin Lymphoma (HL), presented a TEN secondary to antibiotics. She was admitted due to a consumptive syndrome, lymphadenopathy, visceromegaly and severe pancytopenia. Laboratory and bone marrow tests confirmed HFS. Due to constant fever, imipenem was indicated. On the third day she started with pain and skin rash. She evolved with positive Nikolsky sign. Cutaneous biopsy was concordant with extensive TEN, which was managed with intravenous immunoglobulin and dexamethasone. A complete response and normalization of the blood count were achieved. Finally, the lymph node biopsy showed HL of mixed cellularity type, which was managed with 8 cycles of ABVD chemotherapy, achieving complete remission.

NAPD regimen for patients with recurrent refractory diffuse large B-cell lymphoma / 中南大学学报(医学版)

To investigate the clinical efficacy and toxicities for the NAPD regimen (vinorelbine, cytarabine, cisplatin, and dexamethasone) in the treatment of recurrent refractory diffuse large B-cell lymphoma.
 Methods: A total of 30 patients identified with recurrent refractory diffuse large B-cell lymphoma were enrolled in this retrospective study. The curative efficacy of NAPD regimen was evaluated after 2 consecutive cycles. The toxicities and adverse reaction were evaluated after 1 cycle. The objective response rate (ORR), overall survival (OS), progress free survival (PFS), and the rates of 1, 2, and 4-year OS and PFS were analyzed. The prognosis was evaluated with univariate analysis.
 Results: The ORR was 56.7% and clinical benefit rate (CBR) was 83.3% after 2 cycles. Five patients achieved complete remission, 12 achieved partial remission, and 8 achieved stable disease. The median OS was 22 (1.5-140) months. The 1, 2, and 4-year OS rates were 59.1%, 48.2%, and 40.2%, respectively. The median PFS was 14 (1.5-140) months. The 1, 2 and 4-year PFS rates were 56.3%, 42.2%, and 31.7%, respectively. The main adverse reaction was myelosuppression. Three patients suffered from grade III-IV leukopenia and 1 thrombocytopenia. Grade I-II gastrointestinal toxicity was 20%. No heart, liver, and kidney damages at grade III-IV were observed.
 Conclusion: The NAPD regimen is effective and its toxicity is well tolerated for the treatment of recurrent refractory diffuse large B-cell lymphoma. It is a salvage chemotherapy regimen worth to be verified.

A Case of Erdheim-Chester Disease Developed during Treatment of Leukemia in a Child / 임상소아혈액종양

Erdheim-Chester disease (ECD) is a rare non-Langerhan's cell histiocytosis disorder characterized by replacement of normal tissue by lipid-laden histiocytes affecting various organs. A few pediatric cases have been reported worldwide. Here we present a child with leukemia who was diagnosed as ECD. A 2-year and 11-month old boy diagnosed with high risk acute lymphoblastic leukemia (ALL) at the age of 17 months, received allogeneic hematopoietic stem cell transplantation (HSCT) at the age of 2 years old. Six months after the transplantation, the patient was admitted to the hospital with palpable left calf nodules. Bone marrow study suggested ECD without leukemia with complete chimerism status. Excisional biopsy of the left calf nodule showed ‘aggregation of non-Langerhan's cell type epitheloid histiocytes’; clinically suggestive of ECD. The patient was started on vinblastine and corticosteroid treatment.

Outcome of adjuvant chemotherapy with lomustine, vinblastine and chlorambucil on management of canine mast cell tumour of high to intermediate risk / Resultado da quimioterapia adjuvante com lomustina, vimblastina e clorambucil no manejo do mastocitoma canino de risco alto a intermediário

In spite of the many available protocols, the use of chemotherapy for the management of canine mast cell tumours (MCT) remains empirical, and there is lack of criteria for the choice of protocol and definition of patients who may benefit from treatment. The objective of this study was to evaluate the outcome of dogs with MCT after adjuvant chemotherapy according to the risk of recurrence or metastasis proposed on the literature. This prospective study included 89 followed up dogs with prognosis assesment including clinical, histological, immunohistochemical and genetic features of canine MCT. Patients were grouped according to risk of recurrence and metastasis and recommended treatment with lomustine followed by chlorambucil if considered at high-risk, or vinblastine followed by chlorambucil if a patient was at intermediate risk. Outcome was defined by disease-free interval (DFI) and overall survival (OS) estimated by Kaplan-Meier curve. Adjuvant lomustine was useful for control of canine MCT of high-risk of recurrence or metastasis, but only when sequentially associated to chlorambucil with a DFI of 686 days and not reached OS. There was no difference in outcome in the intermediate-risk group despite choosen treatment. Patients at intermediate-to-low risk may not require adjuvant treatments, even in the absence of free surgical margins.(AU)

Apesar dos inúmeros protocolos disponíveis, o uso da quimioterapia permanece empírico para o mastocitoma canino e faltam critérios para escolha do protocolo e da definição dos pacientes que poderiam se beneficiar do tratamento. O objetivo deste estudo foi avaliar o resultado de cães com mastocitoma após a quimioterapia adjuvante, de acordo com o risco de recorrência ou metástase proposto na literatura. Este estudo prospectivo incluiu 89 cães com acompanhamento clínico e avaliação prognóstica, incluindo características clínicas, histológicas, imuno-histoquímicas e genéticas dos mastocitomas. Os pacientes foram agrupados segundo o risco de recorrência ou metástase, sendo recomendado tratamento com lomustina seguida de clorambucila, se considerados sob alto risco, ou vimblastina seguida de clorambucila, se estivessem sob risco intermediário. O resultado final foi definido pelo intervalo livre de doença (ILD) e pela sobrevida global (SG), estimados pela curva de Kaplan-Meier. Na adjuvância, a lomustina foi útil no controle do mastocitoma canino de alto risco, mas apenas quando associada ao clorambucila, com um ILD de 686 dias, sem atingir a mediana para SG. Não houve diferença no grupo de risco intermediário, independentemente do tratamento escolhido. Pacientes de risco intermediário podem não necessitar de tratamentos adjuvantes, mesmo na ausência de margens cirúrgicas livres.(AU)

Linfoma Hodgkin clássico de apresentação incomum. Relato de caso / An unusual presentation of a classic Hodgkin lymphoma. Case report

O linfoma é uma neoplasia originária do sistema linfático, a partir de células linfocitárias. A sintomatologia mais comum é febre, tosse, sudorese noturna, perda de peso, fraqueza e linfoadenopatia indolor. A etiologia ainda permanece desconhecida, tendo sido relacionada ao vírus Epstein-Barr. O diagnóstico se baseia na visualização das células de Reed-Sternberg. O esquema adriamicina, bleomicina, vinblastina e dacarbazina (ABVD) ainda é o tratamento preconizado, associado ou não à radioterapia. Relatamos um caso de linfoma de Hodgkin de apresentação atípica, cujo diagnóstico só foi possível por esplenectomia.(AU)

The lymphoma is a cancer of the lymphatic system originating from lymphocyte cells. The most common symptoms are fever, cough, night sweats, weight loss, weakness, and painless lymphadenopathy. The etiology remains unknown, having been related to the Epstein Barr virus. The diagnosis is based on visualization of Reed Sternberg cells. The adriamycin, bleomicin, vinblastine and dacarbazine (ABVD) regimen is still the preferred treatment, with or without radiation therapy. We report a case of Hodgkin's lymphoma of atypical presentation, the diagnosis of which was only possible through splenectomy.(AU)

Excelente respuesta a tratamiento con ABVD en pacientes con linfoma de Hodgkin localizado / Response to ABVD chemotherapeutic protocol in patients with early stage Hodgkin’s lymphoma

Background: Recent trials show that > 90% of patients with early stage Hodgkin`s Lymphoma (ESHL) can be cured, especially when using the ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapeutic (CT) protocol. The use of radiotherapy (RT) is variable and can be selected according to the presence of specific risk factors, including PET-CT, as recently reported. Aim: To report the experience in the treatment of ESHL. Material and Methods: Retrospective and descriptive analysis of patients with ESHL treated at the Red de Salud UC-Christus between 2011-2015. Results: Twenty-two patients were treated. In 73%, the tumor was of nodular sclerosis histologic type. Most patients (95%) were in stage II, and 78% had a favorable prognosis according to the Deutsche Hodgkin Studiengruppe (GHSG) criteria. All patients were stratified using PET-CT and treated using the ABVD CT protocol, for 4-6 cycles. Only 5 patients received RT. There was no change of conduct after interim-PET-CT results. Ninety one percent of patients achieved complete response and there were two cases of refractory disease. Both cases underwent hematopoietic stem cell transplantation. After 17 months of median follow-up, 91% of patients are relapse-free, and only one patient died (5%). Conclusions: ABVD offers excellent results for ESHL patients. The benefit of PET-CT should be evaluated with prospective protocols, aiming to select patients needing RT or to reduce the number of CT cycles.

Radiation-Induced Giant Cell Granuloma Mimicking Relapsed Hodgkin Lymphoma at FDG-PET/CT / 대한핵의학회잡지

A 22-year-old woman was diagnosed with intermediate risk stage II Hodgkin lymphoma and treated with three cycles of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by involved-field radiation therapy. A complete metabolic remission was achieved after two cycles of ABVD, which was maintained until three years after completion of treatment. Follow-up FDG-PET/CT four years after completion of treatment, however, showed a new FDG-avid (Deauville score of 4) lesion in the right scapula, suggesting relapsed disease. Computer tomography (CT)-guided biopsy of this lesion was performed and subsequent histological examination revealed a radiation-induced giant cell granuloma.

Assessment on the Efficacy and Safety of Aidi Injection Combined with Vinorelbine and Cisplatin for Treatment of Advanced Nonsmall Cell Lung Cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The aim of this study was to assess the efficacy and safety of vinorelbine and cisplatin (NP chemotherapy) alone or in combination with Aidi injection for the treatment of advanced nonsmall cell lung cancer (NSCLC).</p><p><b>METHODS</b>Pertinent publications were identified in PubMed, EMBASE, Cochrane Library, CNKI, CQVIP, and Wanfang databases, up to December 8, 2015. After quality assessment of all included randomized controlled trials evaluating Aidi injection combined with NP chemotherapy for the treatment of advanced NSCLC, a meta-analysis was performed by Review Manager 5.2 and STATA 12.0 for statistical analyses.</p><p><b>RESULTS</b>Twelve studies including 509 and 503 cases in the experimental and control groups, respectively, were finally analyzed. The meta-analysis revealed that when cisplatin dose ranging from 20 to 40 mg/m 2 , combination of Aidi injection and NP chemotherapy was statistically different compared with NP chemotherapy alone in enhancing efficiency (relative risk [RR] = 1.24, 95% confidence interval [CI] [1.05-1.47], P = 0.010) and reducing the incidence of Grade II or above nausea and vomiting (RR = 0.49, 95% CI [0.30-0.80], P = 0.005). Meanwhile, with cisplatin ranging from 80 to 120 mg/m 2 , no significant differences in efficiency (RR = 1.11, 95% CI [0.87-1.42], P = 0.390) and Grade II or above nausea and vomiting (RR = 0.88, 95% CI [0.71-1.10], P = 0.260) were obtained. In addition, Aidi injection combined with NP chemotherapy was superior to NP chemotherapy alone in improving the quality of life, alleviating Grade II or above leukopenia and thrombocytopenia.</p><p><b>CONCLUSIONS</b>Aidi injection combined with NP chemotherapy can enhance efficiency, improve the quality of life, and decrease adverse effects in patients with advanced NSCLC.</p>

Low-dose methotrexate combined with vinorelbine for inoperable desmoid tumor: efficacy and the prognostic factors / 南方医科大学学报

<p><b>OBJECTIVE</b>To characterize the clinical features of desmoid tumor, assess the efficacy of conservative chemotherapy for inoperable desmoid tumor and analyze the prognostic factors.</p><p><b>METHODS</b>From August 2009 to December 2013, 52 patients with inoperable desmoid tumor were treated in our department and received chemotherapy with vinorelbine combined with low-dose methotrexate. The clinical data of the patients were analyzed retrospectively.</p><p><b>RESULTS</b>The patients studied included 22 male and 30 female patients with the age of disease onset ranging from 2 to 46 years (mean 18.7 years). The lesions occurred most frequently in the lower limbs (36.5%, 19/52) and the tumor size ranged from 2.7 to 37 cm (mean 9.5 cm). The patients were followed up for a median of 29 months (7 to 64 months). The chemotherapy lasted for 4 to 30 months (median 12 months). After completion of the chemotherapy, 1 patient had a complete response (CR), 18 showed partial responses (PR), 27 cases had stable disease (SD), and 6 had progressive disease (PD), with an overall response rate (ORR) of 88.5%. The progression-free survival (PFS) time of the patients ranged from 4 to 63 months (median 26.5 months) with a 2-year PFS rate of 76.7% and 5-year PFS rate of 41.9%. A longer chemotherapy duration (over 12 months) was associated with a more favorable prognosis. No significant differences in PFS were found between the patients stratified by gender, age of disease onset, age when receiving chemotherapy, tumor site, or tumor size.</p><p><b>CONCLUSION</b>For recurrent, inoperable and progressive desmoid tumor, long enough cycles of vinorelbine combined with low-dose methotrexate can be an effective and safe option for tumor control.</p>

The efficacy of 2-nitrovinylfuran derivatives against Leishmania in vitro and in vivo

Despite recent advances in the treatment of some forms of leishmaniasis, the available drugs are still far from ideal due to inefficacy, parasite resistance, toxicity and cost. The wide-spectrum antimicrobial activity of 2-nitrovinylfuran compounds has been described, as has their activity against Trichomonas vaginalis and other protozoa. Thus, the aim of this study was to test the antileishmanial activities of six 2-nitrovinylfurans in vitro and in a murine model of leishmaniasis. Minimum parasiticide concentration (MPC) and 50% inhibitory concentration (IC50) values for these compounds against the promastigotes of Leishmania amazonensis, Leishmania infantum and Leishmania braziliensis were determined, as were the efficacies of two selected compounds in an experimental model of cutaneous leishmaniasis (CL) caused by L. amazonensis in BALB/c mice. All of the compounds were active against the promastigotes of the three Leishmania species tested. IC50 and MPC values were in the ranges of 0.8-4.7 µM and 1.7-32 µM, respectively. The compounds 2-bromo-5-(2-bromo-2-nitrovinyl)-furan (furvina) and 2-bromo-5-(2-methyl-2-nitrovinyl)-furan (UC245) also reduced lesion growth in vivo at a magnitude comparable to or higher than that achieved by amphotericin B treatment. The results demonstrate the potential of this class of compounds as antileishmanial agents and support the clinical testing of Dermofural(r) (a furvina-containing antifungal ointment) for the treatment of CL.

Agregação familiar da doença renal crônica secundária à hipertensão arterial ou diabetes mellitus: estudo caso-controle / Family clustering of secondary chronic kidney disease with hypertension or diabetes mellitus. A case-control study

No Brasil, a hipertensão e o diabetes mellitus tipo 2 são responsáveis por 60% dos casos de doença renal crônica terminal em terapia renal substitutiva. Estudos americanos identificaram agregação familiar da doença renal crônica, predominante em afrodescendentes. Um único estudo brasileiro observou agregação familiar entre portadores de doença renal crônica quando comparados a indivíduos internados com função renal normal. O objetivo deste artigo é avaliar se existe agregação familiar da doença renal crônica em familiares de indivíduos em terapia renal substitutiva causada por hipertensão e/ou diabetes mellitus. Estudo caso-controle tendo como casos 336 pacientes em terapia renal substitutiva portadores de diabetes mellitus ou hipertensão há pelo menos 5 anos e controles amostra pareada de indivíduos com hipertensão ou diabetes mellitus e função renal normal (n = 389). Os indivíduos em terapia renal substitutiva (casos) apresentaram razão de chance de 2,35 (IC95% 1,42-3,89; p < 0,001) versus controles de terem familiares com doença renal crônica terminal, independente da raça ou doença de base. Existe agregação familiar da doença renal crônica na amostra estudada e esta predisposição independe da raça e da doença de base (hipertensão ou diabetes mellitus).

In Brazil hypertension and type 2 diabetes mellitus are responsible for 60% of cases of end-stage renal disease in renal replacement therapy. In the United States studies have identified family clustering of chronic kidney disease, predominantly in African-Americans. A single Brazilian study observed family clustering among patients with chronic kidney disease when compared with hospitalized patients with normal renal function. This article aims to assess whether there is family clustering of chronic kidney disease in relatives of individuals in renal replacement therapy caused by hypertension and/or diabetes mellitus. A case-control study with 336 patients in renal replacement therapy with diabetes mellitus or hypertension for at least 5 years (cases) and a control matched sample group of individuals with hypertension or diabetes mellitus and normal renal function (n = 389). Individuals in renal replacement therapy (cases) had a ratio of 2.35 (95% CI 1.42-3.89, p < 0.001) versus the control group in having relatives with chronic renal disease, irrespective of race or causative illness. There is family clustering of chronic kidney disease in the sample studied, and this predisposition is irrespective of race and underlying disease (hypertension or diabetes mellitus).

Analysis of postoperative chemotherapy-related anemia in elderly cancer patients / 中华肿瘤杂志

<p><b>OBJECTIVE</b>This study was conducted to investigate the correlation between anemia and postoperative chemotherapy in elderly cancer patients.</p><p><b>METHODS</b>One hundred and fifty-seven elderly patients ( age ≥ 60) with pathologically confirmed breast, lung and digestive tract cancers, who had HGB ≥ 120 g/L and ECOG scores 0-2, were included in this study. We reviewed their clinicopathological data and analyzed the correlation of anemia in breast cancer patients after 1, 3 or 5 cycles and lung cancer patients after 1, 2 or 3 cycles of postoperative chemotherapy.</p><p><b>RESULTS</b>Among the 157 cases, the overall proportion of anemia was 31.8% (50/157) , with 18.8% in male and 47.2% in female patients (P < 0.001). After three cycles of chemotherapy, the proportion of anemia was 57.9% in lung cancer, 34.5% in breast cancer, 26.3% in gastric cancer and 9.3% in colorectal cancer patients (P < 0.001). The proportion of anemia during 5 cycles chemotherapy (three cycles in lung cancer) was gradually increasing. In the lung cancer patients, anemia was observed in 66.7% of patients who received vinorelbine plus cispiatin regimen and 25.0% of cases who received vinorelbine regimen chemotherapy (P = 0.044).</p><p><b>CONCLUSIONS</b>In most elderly patients with normal hemoglobin level and in good conditions, the chemotherapy-related anemia is mild and less frequent. Age should not limit the adjuvant chemotherapy in elderly cancer patients. Attention should be paid to the possibility of anemia in elderly female lung cancer patients receiving multiple cycle platinum-based chemotherapy regimens.</p>
