ABSTRACT

OBJECTIVE@#To analyze the risk factors, distribution of pathogenic strains and tolerance of pulmonary infection in patients with multiple myeloma(MM) during bortezomib chemotherapy.@*METHODS@#The clinical data of 85 patients with multiple myeloma treated by bortezomib in our hospital from January 2015 to January 2019 was analyzed. The patients were divided into infection group and control group according to whether they were infected. The tolerance, pathogen distribution, and related risk factors were retrospectively analyzed.@*RESULTS@#Pulmonary infection rate was 55.29% in 85 MM patients. The proportions of the patients with anemia, neutropenia, and ECOG score ≥2 points in the infection group were significantly higher than those in the control group (P<0.05). In this study, 30 strains of pathogenic bacteria were detected, with gram-negative bacteria accounting for 60%, gram-positive bacteria for 33.33%, fungi for 3.3% and tuberculosis bacteria for 3.3%. Pseudomonas aeruginosa, klebsiella pneumoniae, streptococcus pneumoniae, staphylococcus aureus accounted showed the highest proportion. Most of MM patients with pulmonary infection showed a heterprognosis after two weeks antibiotic treatment, while 3 patients died. About 30 percent of early deaths were due to pulmonary infections.@*CONCLUSION@#Anemia, neutropenia, ECOG score ≥2 points are the major clinical characteristics of the multiple myeloma patients with pulmonary infections. Pulmonary infection is an important cause of early death in patients with multiple myeloma. Pathogenic bacteria are mainly composed of gram-negative bacteria. Beta-lacta/ beta-lactamase inhibitor combinations or Carbapenems are effective empiric treatment for controlling the progression of pulmonary infection.

ABSTRACT

OBJECTIVE@#To investigate the effect of neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) in the valuation prognosis of patients with multiple myeloma (MM).@*METHODS@#The clinical data of 82 patients with initially diagnosed MM admitted to Gansu Provincial People's Hospital was analyzed retrospectively. NLR and MLR were calculated based on blood routine results respectively. The optimal cut-off point of NLR and MLR was determined according to the ROC curve, and the patients were divided into the high NLR/MLR group and the low NLR/MLR group. The general data, biochemical indicators and prognosis of the patients in each groups were compared respectively. The prognostic significance of the high NLR/MLR group and the low NLR/MLR group in patients between different treatment regimens and different clinical characteristics were analyzed. Risk stratification was designed based on NLR and high MLR as two risk factors, and the effect of risk factors, on the prognosis of MM patients were compared.@*RESULTS@#ROC curve analysis determined that the optimal cut-off point of NLR was 3.1 (sensitivity 75%, specificity 70.7%) and the optimal cut-off point of MLR was 0.34 (sensitivity 83.3%, specificity 53.4%). The lactate dehydrogenase (LDH) and mean platelet volume (MPV) were correlated to NLR and MLR (P<0.05). There were no significant difference in age, sex, serum calcium (Ca), β @*CONCLUSION@#Elevated NLR and MLR are associated with poor prognosis in MM patients and may serve as the cost-effective and readily available prognostic biomarkers.

ABSTRACT

OBJECTIVE@#To explore the correlation of body mass index (BMI), ABO blood group with multiple myeloma (MM).@*METHODS@#70 MM patients (MM group) and 10 healthy people (control group) were selected in the same period, the BMI of patients was calculated according to the height and weight, and the differences of BMI in 2 groups was compared. The distribution of age, sex, albumin (Alb), serum creatinine (Cr), hemoglobin (Hb) and red blood cell (RBC) in the two groups were analyzed. Differences in red blood cell distribution width (RDW), neutrophil/lymphocyte ratio (NLR), disease stage and lactate dehydrogenase (LDH) level, survival rate of MM patients with different BMI values and blood group were compared between two groups, and the differences in follow-up outcomes of MM patients were analyzed by univariate and multivariate logistic regression analysis.@*RESULTS@#BMI level of MM patients was higher than that of control group (t=2.706, P<0.01), but the difference of blood group was not significant (P>0.05); The NLR value in obese patients was higher than that in non-obese patients, the staging was later and the Alb level was lower in obese patients than those in non-obese patients. the differences were statistically significant between obese patients and non-obese patients (P<0.05). Univariate and multivariate analysis showed that BMI, Alb and LDH level could influence the follow-up outcome of MM patients, the patients with elevated BMI and LDH level had worse prognosis, while patients with elevated Alb had better prognosis. which means that all the three factors are independent factors affecting the prognosis of MM patrents.@*CONCLUSION@#Increased BMI in MM patients can affect the outcome of follow-up, which is an independent influencing factor.

ABSTRACT

OBJECTIVE@#To explore and analyze the risk factors of herpes zoster in patients with multiple myeloma (MM) during the chemotherapy with bortezomib.@*METHODS@#Clinical data of 85 MM patients treated with bontizomib from January 2015 to January 2019 were selected and divided into case group and control group accroding to the occurred of herpes zoster. The clinical characteristic, treatment outcome and related factor of herpes zoster were retrospective analyzed.@*RESULTS@#Twenty of the 85 patients with MM treated with bortezomib developed herpes zoster occurred (23.5%). Single-factor analysis showed that age≥65 years, lymphocytopenia occurred before treatment, neutropenia occurred before treatment, ECOG score≥2, application of cyclophosphamide, absence of preventive antiviral therapy were associated with the genesis of herpes zoster (P<0.05). Multivariate logistic regression analysis showed that lymphocytopenia occurred before treatment, the application of cyclophosphamide and the absence of preventive antiviral therapy were the independent risk factors for herpes zoster (P<0.05).@*CONCLUSION@#The incidence of herpes zoster is high in the multiple myeloma patients treated with bortezomib. Lymphocytopenia occurred before treatment, the application of cyclophosphamide, and the absence of prophylactic antiviral therapy are the important risk factors for herpes zoster, for which the clinicians should attach great importance.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression of motilin and its precursor mRNA in normal human thyroid. To compare the expression differences of motilin and it precursor mRNA between normal thyroid and intestines. To study the expression of motilin and its precursor mRNA in human thyroid tumors and their clinical implications.</p><p><b>METHODS</b>RT-PCR, Southern blot and molecular cloning were used to detect motilin transcript expression in human thyroid and mucous membrane of small intestine. Real-time PCR and immunohistochemical techniques were used to quantify motilin precursor mRNA and motilin peptide in thyroid tissue samples including adenoma, medullary carcinoma, follicular carcinoma, papillary carcinoma and nodular goiter.</p><p><b>RESULTS</b>(1) The expression of motilin and its precursor mRNA in normal human thyroid was primarily in the thyroid C cells. (2) RT-PCR and Southern blot showed that motilin mRNA expressed in human thyroid was identical to that expressed in duodenum with identical sequence deposited in NCBI Genbank of America. (3) Immunohistochemistry, Western blot research and real-time PCR studies showed that motilin and its precursor mRNA were expressed in normal and tumor tissues of human thyroid. Thyroid tumors (acidophilic adenoma, medullary carcinoma, follicular carcinoma, papillary carcinoma and nodular goiter) showed intense and diffuse immunostaining for motilin peptide. Moreover, the expression of motilin and its precursor mRNA in thyroid medullar carcinoma and acidophilic adenoma were significantly higher than those of normal thyroid tissue (P < 0.05). The expression in thyroid follicular and papillary carcinomas were significantly lower than those of normal thyroid tissue (P < 0.05). There was no difference of the expression between nodular goiter and normal thyroid tissue (P > 0.05).</p><p><b>CONCLUSIONS</b>Motilin peptide and its precursor mRNA are expressed in C cells of human thyroid. The sequence of motilin is identical to that expressed in duodenum from NCBI Genbank of America. The expressions of both motilin and its precursor mRNA in thyroid medullary carcinoma and acidophilic adenoma are significantly increased. In contrast, their expressions in thyroid follicular and papillary carcinomas are significantly decreased. Motilin may regulate physiological functions of the thyroid through parafollicular cells. Motilin may be involved in the pathogenesis of medullary carcinoma and acidophilic adenoma of the thyroid.</p>
