To investigate the effect of splenectomy on lymphocyte subpopulations we monitored changes in serum concentrations of soluble suppressor/cytotoxic (sCD8) and soluble helper/inducer (sCD4) antigen in 11 splenectomized patients. Indications for splenectomy were hereditary spherocytosis in 2, idiopathic thrombocytopenic purpura in 2, gastric carcinoma in 4, Hodgkin's disease in 2 and pancreatitis in 1 patient. Lymphocyte subpopulations were also analyzed by means of conventional immunophenotyping with monoclonal antibodies to CD4 and CD8. We consistently found an early postoperative drop of sCD8 and sCD4 levels within the first week after splenectomy, paralleling changes in the percentages of CD4+ and CD8+ lymphocytes. While alterations of lymphocyte subsets in the peripheral blood were completely reversible and sCD4 levels returned to preoperative values, sCD8 concentrations remained suppressed even 3 months after splenectomy. SCD8 levels at the nadir and those 3 months after splenectomy were significantly lower than preoperative values (P = 0.003, P = 0.149 respectively). Since sCD8 levels reflect suppressor/cytotoxic cell activity, we suggest that suppressor cell activity is reduced in splenectomized patients.

Two hundred patients with various haematological diseases underwent splenectomy between 1974 and 1986. The diagnoses were: Hodgkin's disease (n = 76), hairy cell leukaemia (n = 25), idiopathic thrombocytopenic purpura (n = 20), chronic lymphatic leukaemia (n = 19), haemolytic anaemia (n = 18), non-Hodgkin lymphoma (n = 16), myelofibrosis (n = 10), chronic myeloid leukaemia (n = 6), spherocytosis (n = 4), and miscellaneous (n = 6). Many of the patients were treated with corticosteroids and in poor general condition, partly as a result of chemotherapy. There were 37 postoperative complications in 29 patients (14.5%); two died, both of septicaemia. Pneumonia, bleeding, and wound infection were the most common complications, occurring in 9, 8, and 6 patients, respectively. Twelve patients required reoperation, eight for bleeding, two for intra-abdominal abscesses, and one each for pancreatitis and bowel perforation. There was no association between the diagnosis and the type of postoperative complication, but patients whose spleens weighed more than 2 kg had an increased incidence of postoperative complications (30%). We conclude that elective splenectomy is a safe treatment for haematological diseases, even in high risk patients.

Intramural duodenal hematoma in children is one of the least common injuries encountered. Because of the rarity of this problem, there has been little conformity of opinion as to the relative merits of operative vs nonoperative management. We reviewed 182 cases of this condition, of which 168 were taken from the English literature and 14 from our hospital. Pancreatitis was the most common associated intra-abdominal lesion (21%), while central nervous system, skeletal, and thoracic injuries (5%) accounted for the major extra-abdominal injuries. Hemophilia, von Willebrand's disease, and idiopathic thrombocytopenic purpura occurred in 7 cases and played a major role in the prognosis. Of these cases, 121 patients were treated surgically and 61 conservatively. The average hospitalization was 14 days for the surgical group and 11 days for the conservative group. There were 18 complications in the surgical group. It appears that most patients with intramural duodenal hematoma would respond well to conservative management. Surgery should be reserved for those cases that remain obstructed over seven to ten days or have evidence of perforation.

We prospectively evaluated 139 consecutive children presenting to the Sanjay Gandhi Postgraduate Institute of Medical Sciences (Lucknow, India) with gastrointestinal (GI) bleeding from January 1991 to November 1994. Our aims were to find out whether the causes of GI bleeding in a developing country differed from developed countries and how the application of newer diagnostic techniques would help in the diagnosis of GI bleeding. Barium studies, endoscopy, technetium-99m-labelled (erythrocytes and pertechnetate) scans, selective abdominal angiography using a digital subtraction technique and rectal endoscopic ultrasonography were performed. Upper GI bleeding (n = 75) was variceal in 71 (95%) children (extrahepatic portal venous obstruction in 65, cirrhosis in six) and non-variceal in four (5%) cases (Henoch-Schonlein purpura, idiopathic thrombocytopenic purpura, drug-induced gastric erosions and pseudoaneurysm of the gastroduodenal artery due to idiopathic chronic calcific pancreatitis). Causes of lower GI bleeding (n = 64) were colitis (27 cases; 42%), colorectal polyps (26 cases; 41%), enteric fever (n = 3), solitary rectal ulcer (n = 3), portal hypertensive colopathy (n = 2), colonic arteriovenous malformation (n = 1) and internal haemorrhoids (n = 1). One patient remained undiagnosed. Angiography performed in four children was diagnostic in two. In one child with massive lower GI bleeding from portal colopathy, the bleeding site (caecum) was localized by intra-operative colonoscopy, while in the other child with portal colopathy, rectal endoscopic ultrasonography was performed to substantiate the diagnosis. We conclude that the causes of upper GI bleeding in children in developing countries are different from those in developed countries (variceal bleeding due to extrahepatic portal venous obstruction is the most common cause, while peptic ulcer is rare). However, the spectrum of lower GI bleeding is similar to that of developed countries. Application of newer diagnostic techniques is helpful and safe in the identification of the cause of GI bleeding in children.

The study was conducted on 75 multitransfused children aged between 2 and 13 years who attended the Department of Paediatrics, LNJPN Hospital, New Delhi from July 1990 to July 1991. These included 64 cases of thalassaemia major, 4 cases of haemophilia, 3 patients of acute lymphatic leukaemia and one each of acute myeloid leukaemia, aplastic anemia, chronic idiopathic thrombocytopenic purpura and acute haemorrhagic pancreatitis. HBsAg was tested in all, Anti-HBc was tested in 44 patients and Anti-HCV in 43 patients. Anti HDV was tested in HBsAg positive patients and IgM anti-HAV was tested in patients suffering from hepatitis. Liver function tests were evaluated in all patients. HBsAg was positive in 31% of patients; 40% of males and 15% of females were HBsAg positive, the difference being statistically significant. 84% of patients were Anti-HBc positive, 21% were anti HCV positive, 4% were Anti HDV positive. 15% of the patients had post transfusion hepatitis. Anti HCV was present in 57% of the hepatitis patients; none had anti-HAV IgM.

We conducted a retrospective multicenter study by questionnaire to evaluate the results of laparoscopic splenectomy for idiopathic thrombocytopenic purpura (ITP). Between 1991 and 1998, 209 patients with a mean age of 41.2 years (range, 10-83) had a laparoscopic splenectomy for idiopathic thrombocytopenic purpura. Preoperatively, 178 patients (85%) underwent medical treatment aimed at achieving a satisfactory platelet count. Twenty-nine patients were obese, with a body mass index greater than 30%, and 14% were HIV-seropositive. The so-called hanging spleen technique in the right lateral decubitus position was used most often. The average duration of surgery was 144 minutes (45-360). This was significantly longer in cases of conversion (170 minutes; P < 0.01). The factors influencing the duration of laparoscopy were operator experience and patient obesity (P < 0.01). A conversion was necessary in 36 cases (17.2%) because of hemorrhage. The conversion rate varied from 5.3% to 46.7%, depending on the surgical team. A multivariate analysis of factors disposing to conversion identified two causes: obesity and operator experience. One or more accessory spleens were found in 34 patients (16.2%). The average weight of the spleens was 194.2 g. There were no deaths. There were no complications in 187 patients (89.5%), with a mean hospital stay of 6.1 days. Patients who did not require a conversion had a significantly earlier return of intestinal transit, used less analgesic, and had a shorter length of hospitalization. Overall morbidity was 10.5% (22 cases), due to subphrenic collections (7 cases), abdominal wall complications (6 cases), re-intervention for actual or suspected hemorrhage or pancreatitis (3 cases), pneumopathology (2 cases) and others (4 cases). A multivariate analysis about morbidity shows a statistically significant difference in conversions (P < 0.05) but not in obesity or in surgeon's experience. Normal activity was achieved on average by the twentieth postoperative day--earlier if conversion was not required (18.4 versus 33.9 days). The average preoperative platelet count was 92.7 x 10(9)/L (range, 3 to 444). Twenty patients had a count of less than 30 x 10(9)/L and in this group the conversion rate was 30% (6 cases). Ninety-six patients were seen in the outpatient clinic, with an average follow-up time of 16.2 months (3 to 72 months), and the average platelet count was 242 x 10(9)/L (6 to 780). Eight patients (8.3%) were failures with a platelet count of <30 x 10(9)/L. In the 20 patients with a preoperative platelet count <30 x 10(9)/L, there were 3 early failures and 5 late relapses. There were 2 late deaths: chest infection at 3 months in an HIV seropositive patient and one case of pulmonary embolus at 6 months. Laparoscopic splenectomy constitutes a real alternative to conventional splenectomy for the treatment of idiopathic thrombocytopenic purpura. It is associated with fewer postoperative complications, a shorter duration of hospitalization and an earlier return to normal activity. The limiting factors are the experience of the operator and patient obesity. The long-term results are identical to those of conventional splenectomy, with a better than average success rate in patients that have failed preoperative medical treatment.

For a long time fibrinopeptide A(FPA), fibrinopeptide B(FPB), D-dimer, FM test, serum FDP, and thrombin anti-thrombin complex(TAT) are being used as molecular markers to for sure diagnose hypercoagulable state and thrombus formation. Indeed these molecular markers are very useful for diagnosing thrombus formation, disseminated intravascular coagulation(DIC), and the indicator of treatment of DIC. But these molecular parameters are not enough and difficult for prognosis of the disease or predicting the complication of patients as the most important subject for clinicians. The soluble fibrin monomer-fibrinogen complex (SF) is a complex coupling fibrin monomer and fibrinogen molecules to be formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of thrombus formation and DIC, in particular its early stage. The aim of the present study is to evaluate a potential usefulness of a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters in 195 patients with DIC, subclinical DIC/hypercoagulable state, and non-DIC. The diagnosis of DIC was made based on a modified version of the criteria established by the Ministry of Health, Labor and Welfare of Japan. Underlying disease includes leukemia, malignant lymphoma, myelodysplastic syndrome (MDS), multiple injury, giant ovarian tumor, prostatic cancer with multiple bone metastasis, lung cancer, breast cancer with multiple lung and bone metastasis, severe pneumoniae, sepsis, hemophagocytic syndrome (HPS), and rheumatoid arthritis. The SF levels in DIC patients were significantly higher than those in the subclinical DIC/hypercoagulable state, and the non-DIC patients. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of DIC and contribute to legitimate managements of patients with DIC. The excessive life response to serious clinical insults, such as sepsis, severe pancreatitis, trauma and shock, is called systemic inflammatory response syndrome (SIRS). Once SIRS occurs, people may often die from serious complications such as adult respiratory distress syndrome (ARDS), acute lung injury (ALI), disseminated intravascular coagulation (DIC) and multiple organ failure (MOF). Especially, ALI followed by pneumoniae associated with SIRS could depend on patient's prognosis and life. That is to say, it seems to be urgent for clinicians to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae (SP). Soluble fibrin monomer-fibrinogen complex(SF) is formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of coagulopathy, in particular its early stage. The aim of the present study is to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae(SP) by using a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters, hemogram, blood laboratory items in 7 patients with PASC and 17 patients with SP. The diagnosis of Pneumoniae was defined according to the criteria: clinical symptoms abnormal shadow in both Chest X-p and Chest CT, increased level of CRP, number of WBC. The diagnosis of SIRS was based on the criteria established by American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) Consensus Conference held in August of 1991 in Northbrook, IL (USA). Underlying disease includes leukemias, malignant lymphoma, myelodysplastic syndrome (MDS), multiple myeloma, idiopathic thrombocytopenia purpura(ITP), multiple injury (bone fracture), cerebral hemorrhage, enterocolitis, Appendicitis, lung cancer, larynx cancer, bronchiolitis obliterans organizing pneumonia(BOOP), chronic obstructive pulmonary disease(COPD), sepsis. The SF levels in PASC patients are significantly higher than those in SP patients (p < 0.001). Otherwise, there is no significant difference of the CRP levels between in PASC group and SP group (p < ns). There is no co-relationship between SF level and D-dimer level. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be quite satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of PASC and contribute to legitimate managements of patients with PASC.

Adverse drug reactions to azathioprine (AZA), the pro-drug of 6-mercaptopurine (6-MP), occur in 15% to 28% of patients and the majority are not explained by thiopurine methyltransferase (TPMT) deficiency. Inosine triphosphate pyrophosphatase (ITPase) deficiency results in the benign accumulation of the inosine nucleotide ITP. 6-MP is activated through a 6-thio-IMP intermediate and, in ITPase deficient patients, potentially toxic 6-thio-ITP is predicted to accumulate. The association between polymorphism in the ITPA gene and adverse drug reactions to AZA therapy was studied in patients treated for inflammatory bowel disease. Sixty-two patients with inflammatory bowel disease suffering adverse drug reactions to AZA therapy were genotyped for ITPA 94C>A and IVS2 + 21A>C polymorphisms, and TPMT*3A, *3C, *2 polymorphisms. Genotype frequencies were compared to a consecutive series of 68 controls treated with AZA for a minimum of 3 months without adverse effect. The ITPA 94C>A deficiency-associated allele was significantly associated with adverse drug reactions [odds ratio (OR) 4.2, 95% confidence interval (CI) 1.6-11.5, P = 0.0034]. Significant associations were found for flu-like symptoms (OR 4.7, 95% CI 1.2-18.1, P = 0.0308), rash (OR 10.3, 95% CI 4.7-62.9, P = 0.0213) and pancreatitis (OR 6.2,CI 1.1-32.6, P = 0.0485). Overall, heterozygous TPMT genotypes did not predict adverse drug reactions but were significantly associated with a subgroup of patients experiencing nausea and vomiting as the predominant adverse reaction to AZA therapy (OR 5.5, 95% CI 1.4-21.3, P = 0.0206). Polymorphism in the ITPA gene predicts AZA intolerance. Alternative immunosuppressive drugs, particularly 6-thioguanine, should be considered for AZA-intolerant patients with ITPase deficiency.

Lupus cystitis was rare but frequently resulted in obstructive uropathy and had a strong association with gastrointestinal (GI) symptoms. We treated six patients with systemic lupus erythematosus (SLE) and obstructive uropathy from January 1996 to December 2001 in a university hospital. Evidence of cystitis was obtained from cystoscopic biopsy or the presence of thickened bladder wall in image study. Similar to other reports, five patients had GI manifestations such as abdominal pain, nausea/vomiting, diarrhoea or ileus. In addition, mesenteric lymphadenopathy or pancreatitis was noted in three patients. Two patients had been treated for idiopathic thrombocytopenic purpura (ITP), four and 20 years ago, respectively. All six patients had antibodies to double-stranded DNA (dsDNA). Five patients each had antibodies to cardiolipin (IgG aCL) or SSA. The high prevalence of anti-SSA had also been reported in Chinese lupus patients with intestinal pseudo-obstruction, a clinical manifestation frequently associated with bilateral ureterohydronephrosis. Two patients died of intractable infection after the surgical procedures for persistent ureterohydronephrosis and both patients had antibodies to ribosomal P proteins. Lupus cystitis might not be so rare in Chinese patients with SLE. The diagnosis should be kept in mind when lupus patients have urinary and/or GI symptoms.

Inosine triphosphate pyrophosphatase (ITPase) deficiency occurs with polymorphic frequencies in Caucasians and results in the benign accumulation of the inosine nucleotide ITP. In 62 patients treated with azathioprine for inflammatory bowel disease, the ITPA 94C>A deficiency-associated allele was significantly associated with adverse drug reactions (OR 4.2, 95% CI 1.6-11.5, p = 0.0034). Significant associations were found for flu-like symptoms (OR 4.7, 95% CI 1.2-18.1, p = 0.0308), rash (OR 10.3, 95% CI 4.7-62.9, p = 0.0213) and pancreatitis (OR 6.2, CI 1.1-32.6, p = 0.0485). Polymorphism in the ITPA gene thus predicts AZA intolerance. Alternative immunosuppressive drugs, particularly 6-thioguanine, should be considered for AZA-intolerant patients with ITPase deficiency.
