The immune response to any stimulus is complex, requiring coordinated action by several types of cells in a tightly regulated sequence. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Although regular moderate exercise appears to be important factor for increasing immunity, Athletes are susceptible to illness, in particular upper respiratory track infection, during periods of intense training and after competition. In addition, in elite athletes, frequent illness is associated with overtraining syndrome, a neuroendocrine disorder resulting from excessive training. Through this paper, we want to investigate the effects of exercise on the immunosuppression such as exercise induced lymphopenia, asthma, anaphylaxis, URT (upper respiratory track), and TB (tuberculosis) infection. and also, we want to suggest a direct mechanism, protection and therapy of exercise induced immunosuppression.

Papuloerythroderma of Ofuji is a rare, distinctive clinical entity characterized by a widespread pruritic eruption of coalescence of flat-topped erythematous papules producing an erythroderma with sparing of the skin folds (the 'deck-chair' sign). Other common features of papuloerythroderma are blood eosinophilia, lymphopenia, a raised serum IgE and a nonspecific or eczematous-like histopathologic feature. Its etiology has been reported as variable, and the condition is thus considered as a pattern of cutaneous expression induced by a range of pathological process for systemic disease. We experienced a 71-year-old male patient with a 4-month history of a generalized pruritic eruption which clinical features were compatible with papuloerythroderma of Ofuji. Treatment with systemic steroid resulted in marked improvement.

PURPOSE: We evaluated the clinical/laboratory characteristics and progress of pediatric patients hospitalized for pneumonia and laboratory-confirmed H1N1 influenza infection. METHODS: A total of 101 patients were enrolled. They were divided into 2 groups: group 1 with a fast respiration rate for age (n=66) and group 2 with an appropriate respiration rate for age (n=35). We retrospectively reviewed the medical charts to collect data on the hospitalized patients. RESULTS: Patients were significantly older in group 1 than in group 2 (median age, 7 vs. 4 years, p<0.001) and 59.0% were between 6 and 8 years of age. Sixteen patients (24.2%) in group 1 had underlying medical conditions, most of whom had asthma, and 50 were previously healthy. Oxygen saturation on admission day was significantly lower in group 1 than in group 2 (92% vs. 98%, p<0.001) and 42 patients (63.6%) in group 1 had hypoxia (oxygen saturation <= 92%). The frequency of lymphopenia was significantly higher in group 1 than in group 2 (n=59 vs. 11, p<0.001). Some patients in group 1 received systemic corticosteroid therapy, intravenous immunoglobulin infusion and oxygen supplement (n=28, n=16, n=48, respectively). The frequency of systemic corticosteroid therapy and oxygen supplement was higher in group 1 than in group 2 (p<0.001 for each). CONCLUSION: H1N1 influenza infection complicated by pneumonia can cause severe illness in previously healthy children more than 6 years old and in children with uncontrolled allergic disease. Multi-center studies are needed to evaluate the clinical and epidemiologic characteristics of pediatric patients with 2009 H1N1 influenza.

BACKGROUND: Advances in the understanding of Hodgkin's lymphoma (HL) show various functions of infiltrating immune cells and cytokines in relation to clinical outcomes. The expression of CD163 and c-Met has been suggested to have a role in lymphoid malignancy. Thus, we evaluated the expressions of CD163, c-Met, and serum free light chain (sFLC) in relation to the clinicopathological features of patients with advanced classical HL (cHL). METHODS: We assessed the expression of CD163 and c-Met in 34 patients with cHL through immunohistochemistry on the lymph node biopsy sections and the levels of pretreatment sFLC were estimated using ELISA. RESULTS: High CD163 expression correlated with increased age, B symptoms, International Prognostic Score (IPS) > or =3, mixed cellularity subtype, and low response to treatment. Further, high c-Met expression correlated with increased age at diagnosis, leukocytosis, B symptoms, and lower chance to achieve complete remission. The sFLC levels correlated with increased age at diagnosis, lymphopenia, IPS > or =3, B symptoms, and lower complete remission rates. CONCLUSION: In advanced cHL, increased expression of CD163 and c-Met showed a significant association with adverse prognostic parameters and poor response to treatment. Pretreatment high sFLC level also correlated with poor risk factors, suggesting its use as a candidate prognostic marker. A comprehensive approach for prognostic markers might represent a step towards developing a tailored therapeutic approach for HL.

There have been some 50 reports on the blood pictures of leprosy patients, but all of them have been dealt with the peripheral blood and more over each investigator presented the different data. In order to find cut the typical blood pictures both peripheral and bone marrow as well as the blood pictures between the various types of leprosy and the nature of anemia brought about after the use of D.D.S. derivatives, the author examined the blood of 53 cases of early leprosy patients with the following results: 1. Peripheral Blood Pictures: a. About one third of leprosy patients showel the anemic blood picture and one half of T type leprosy cases gave the anemic picture. Almost all of them were normocytic and hypochromic anemia. b. Shift to the left was found in about 50% of the cases. c. Eosinophilia was observed in the majority of the cases and all of the T type showed eosinophilia. d. There was found lymphocytosis in approximately one third of total cases and half of T type patients showed lymphocytosis. e. Lymphopenia was encountered in one fourth of them and was most frequently seen in L type patients. F. About half of all cases showed monocytopenia. g. Only 10% of patients showed the accelaration in Erythrocyte Sedimentation Rate. 2. Bone Marrow Findings: a. Myeloblastosis was noted in about 50% of them and more frequently seen in T type and I group than the other types. b. There was observed eosinophilia in almost all cases and especially its frequency was higher in T type and I group. c. Lymphocytosis was found in about one third of the total eases and its frequency was highest in L type. whereas in the peripheral blood the lymphocytosis was most frequently seen in T type. d. Plasmocytosis was noted in the majority of the patients and was found in all cases of T type and I group. 3. Seventy percent of the cases showed the increased WBC alkaline phosphatase. 4. No granulomatous changes or any other pathological changes were noted in the histological section of the bone marrow

Primary intestinal lymphangiectasia is a congenital lymphatic disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein losing enteropathy. As a result, generalized edema, hypoalbuminemia, and lymphocytopenia are clinically manifested. We could not find the reason by several examinations. Therefore, we performed double balloon enteroscopy (DBE), and intestnal lymphangiectasia was diagnosed histologically by a biopsy. DBE is a safe and effective method to diagnose small bowel lymphangiectasia. We report a case of primary intestinal lymphangiectasia, which occurred in a 54-year-old male patient with generalized edema and ascites.

We described a 22-month-old girl, who suffered from a gereralized edema and intermittent diarrhea for 1 month. Intestinal lymphangiectasia was confirmed by endoscopic biopsy. Endoscopic examination revealed showed the characteristic appearance of tiny white flakes scattered in the duodenum, which a histological examination confirmed to be dilated lymph vessels. The other findings from laboratory examinations included lymphopenia, hypoproteinemia, hypogammaglobulinemia and increased fecal a1-antitrypsin clearance. Treatment consisting of a low-fat diet and MCT supplementation was successful. The therapy has resulted in the disappearance of duodenal lesions previously observed endoscopically.

OBJECTIVE: To investigate the relationship between early lymphocyte responses and the prognosis in severely injured patients. METHODS: Consecutive patients with severe trauma who were treated in Peking University People's Hospital Trauma Medical Center between June 2017 and June 2020 were enrolled in this restropective chart-review study. According to the responses of lymphocyte after severe injury, the patients were divided into three groups, group 1: lymphopenia-returned to normal; group 2: persistent lymphopenia; group 3: never lymphopenic, and the outcome of 28 d were recorded. Clinical data such as gender, age, base excess, mechanism of injury, Glasgow coma scale (GCS), injury severity score (ISS) and massive blood transfusion were collected. Perform statistical analysis on the collected clinical data to understand the trend of lymphocyte changes in early trauma and the relationship with prognosis. In order to eliminate the interference of age, stratification was carried out according to whether the age was ≥ 65 years old, in different age groups, they were grouped according to whether the length of stay was ≥ 28 d, and the relationship between lymphocyte trend and length of stay was discussed. RESULTS: A total of 83 patients were included, 66 males and 17 females. The main injury mechanisms were traffic accident injuries and high-altitude fall injuries. The average ISS was (30±11) points. 65 patients had lymphopenia on the day of injury, 32 of them returned to normal on the 5th day, and the rest did not recover; the other 18 patients had normal lymphocyte levels after injury. Patients which are failure to normalize lymphopenia within the first 5 days following admission was related with the long hospitalization time and higher 28 d mortality rate. After further stratification by age, failure to normalize lymphopenia within the first 5 days following admission in the elderly group (age ≥65 years) was a risk factor for prolonged hospital stay (≥28 d), P=0.04. While in younger group, a high level of neutrophils within the first 5 d following admission was a risk factor for bad outcome. CONCLUSION A failure to normalize lymphopenia in severely injured patients is associated with significantly higher mortality and longer hospital stay. This study reveals lymphocytes can be used as a reliable indicator for the prognostic evaluation.

Good's syndrome is the association of thymoma with immunodeficiency, characterized by hypogammaglobulinemia, B-cell lymphopenia and variably defects in cellular immunity with CD4+ T-cell lymphopenia and an inverted CD4+:CD8+ T-cell ratio. We report a 43-year-old male patient who presented with a 18-month history of productive cough and postnasal drip. One year ago, he underwent the operation for resection of a thymoma. Despite of appropriate management, sinusitis relapsed multiple times. He was found to have hypogammaglobulinemia with nearly absent B cells(4/microliter). The CD4+ T-cell count was 554/microliter with an inverted CD4+:CD8+ T-cell ratio of 0.6. His symptoms and signs improved with antibiotic treatment and monthly administration of intravenous immunoglobulin (IVIG, 400 mg/kg).
