Primary myelofibrosis (PMF) is easily confused with cirrhosis, due to its main clinical manifestations of splenomegaly and the blood cytopenia. This review focuses on clinical studies to identify primary myelofibrosis and cirrhosis related portal hypertension, to analyze the differences between the two diseases, in order to distinguish PMF and cirrhosis from the pathogenesis, clinical manifestations, laboratory examinations and treatment principles, and simultaneously improve clinicians' understanding of PMF, which is a reference for exploring the early screening or diagnostic indicators of PMF, also provides a clinical basis for the application of new targeted drugs such as ruxolitinib.

Hemophagocytic lymphohistiocytosis (HLH) was a life-threatening syndrome due to the uncontrolled immune activation of cytotoxic T lymphocytes, natural killer (NK) cells, and macrophages. HLH is characterized by primary and secondary causes, the early diagnosis and treatment of patients are closely related to the prognosis and clinical outcome of patients. The clinical presentation is variable but mostly includes prolonged fever, splenomegaly, coagulopathy, hypertriglyceridemia, and hemophagocytosis, none of them is specific and particular for HLH. Tuberculosis (TB) infection is one of the causes of HLH. HLH caused by TB is very rare clinically, but it has a high mortality. For patients with fever of unknown origin, HLH-related clinical manifestations sometimes present before the final diagnosis of TB, and HLH is associated with the most significant mortality rate. This article is mainly about a 28-year-old patient with HLH who suffered from severe TB infection. The patient attended a hospital with a history of 2 months of prolonged fever, 10 days booger and subcutaneous hemorrhage in lower limbs. Before this, he was in good health and denied any history of tuberculosis exposure. Combined with relevant laboratory test results (such as splenomegaly, hemoglobin, platelet count, and hypertriglyceridemia) and clinical manifestations (e.g. fever), the patient was diagnosed with hemophagocytic lymphohistiocytosis, but the etiology of HLH remained to be determined. To confirm the etiology, the patient was asked about the relevant medical history (intermittent low back pain) and was performed chest CT scan, bone marrow biopsy, and fundus photography. Finally, he was diagnosed with hemophagocytic lymphohistiocytosis caused by hematogenous disseminated pulmonary tuberculosis. In response to this, intravenous methylprednisolone and anti-tuberculosis treatment (isoniazid, pyrazinamide, moxifloxacin, and amikacin) were administered to the patient. After more than a month of treatment, the patient recovered from HLH caused by severe TB infection. Therefore, this case suggests that we should be vigilant to the patient who admitted to the hospital with fever for unknown reasons, to diagnose HLH as early as possible and clarify its cause, then perform interventions and treatment, especially HLH secondary to tuberculosis. Also, cases of atypical TB and severe TB should be carefully monitored to achieve early diagnosis and early intervention.

Although the clinical benefit of laparoscopic splenectomy and devascularization (LSD) has been elaborated in many studies, its application in massive splenomegaly remains controversial. We conducted a retrospective research to assess the curative efficacy of LSD for massive splenomegaly due to portal hypertension. Forty-seven patients with massive splenomegaly due to portal hypertension were enrolled in this study, and divided into two groups. Twenty-one patients underwent open splenectomy and devascularization (OSD) from June 2010 to October 2012 (OSD group). From March 2013 to February 2015, LSD was performed on 26 patients (LSD group). Perioperative variables were analyzed. Compared to OSD, LSD was associated with less blood loss (241.9±110.0 mL vs. 319.0±139.5 mL, P<0.05), more rapid resumption of oral diet (2.46±0.95 days vs. 3.76±1.09 days, P<0.05), and shorter postoperative hospital stay (5.35±1.65 days vs. 7.24±1.55 days, P<0.05). It was concluded that for patients with massive splenomegaly due to portal hypertension, LSD is feasible and as safe as OSD.

OBJECTIVETo compare the clinical features of children with different clinical forms of congenital hepatic fibrosis (CHF), and provides a description of the characteristics of childhood CHF.

METHODSSixty children with CHF between January 2002 and June 2015 were enrolled, including 26 children with portal hypertensive CHF (PH CHF), 3 children with cholangitic CHF, 30 children with combined portal hypertensive and cholangitic CHF (mixed CHF), and 1 child with latent forms of CHF. The medical data of 26 children with PH CHF and 30 children with mixed CHF, including gender, age, clinical manifestations, physical signs, laboratory tests and imaging characteristics, were retrospectively studied.

RESULTSFever, jaundice and hepatomegaly were more frequently noted in children with mixed CHF than in those with PH CHF (P<0.05). Splenomegaly and liver cirrhosis occurred more often in children with CHF, but there was no significant difference in the incidences of splenomegaly and liver cirrhosis between the children with PH CHF and mixed CHF. The plasma prothrombin activity, white blood cell counts, platelet counts, mean platelet volume, serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, γ-glutamyl transferase, leucine aminopeptidase, and total bile acids in children with mixed CHF were higher than in those with PH CHF (P<0.05). The decreased international normalized ratio and lower serum albumin levels were more frequently observed in children with mixed CHF than in those with PH CHF (P<0.05).

CONCLUSIONSPH and mixed CHF are common forms in childhood CHF. The children with the two forms of PH usually manifest portal hypertension such as cirrhosis and hepatosplenomegaly. The liver damage may be common in children with mixed CHF.

Some recent studies have found regression of liver cirrhosis after antiviral therapy in patients with hepatitis C virus (HCV)-related liver cirrhosis, but there have been no reports of complete regression of esophageal varices after interferon/peg-interferon and ribavirin combination therapy. We describe two cases of complete regression of esophageal varices and splenomegaly after interferon-alpha and ribavirin combination therapy in patients with HCV-related liver cirrhosis. Esophageal varices and splenomegaly regressed after 3 and 8 years of sustained virologic responses in cases 1 and 2, respectively. To our knowledge, this is the first study demonstrating that complications of liver cirrhosis, such as esophageal varices and splenomegaly, can regress after antiviral therapy in patients with HCV-related liver cirrhosis.

To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
 Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis.
 Results: The clinical manifestations of pulmonary histoplasmosis were mild, such as dry cough. However, the main clinical symptoms of progressive disseminated histoplasmosis were severe, including recurrence of high fever, superficial lymph node enlargement over the whole body, hepatosplenomegaly, accompanied by cough, abdominal pain, joint pain, skin changes, etc.Laboratory examination showed pancytopenia, abnormal liver function and abnormal coagulation function. One pulmonary case received the operation of left lower lung lobectomy, 3 cases of pulmonary histoplasmosis and 6 cases of progressive disseminated histoplasmosis patients were given deoxycholate amphotericin B, itraconazole, voriconazole or fluconazole for antifungal therapy. One disseminated case discharged from the hospital without treatment after diagnosis of histoplasmosis, and 1 disseminated case combined with severe pneumonia and active tuberculosis died ultimately.
 Conclusion: As a rare fungal infection, histoplasmosis is easily to be misdiagnosed. The diagnostic criteria depends on etiology through bone marrow smear and tissues biopsy. Liposomeal amphotericin B, deoxycholate amphotericin B and itraconazole are recommended to treat infection for histoplasma capsulatum.

OBJECTIVETo analyze the clinical characteristics of three Chinese cases of Niemann-Pick disease type C patients with neonatal cholestasis as initial presentation, and enhance awareness of Niemann-Pick disease type C among pediatricians.

METHODThree sporadic cases with confirmed Niemann-Pick disease type C initially presented as neonatal cholestasis were retrospectively reviewed in this study. Their peripheral blood specimens were collected after obtaining informed consent. All exons and the intron-exon boundaries of NPC1 gene were examined by bi-directional sequencing.

RESULTThree patients, 1 female and 2 males, aged from 2 months to 5 years and 10 months, all first complained of jaundice in the neonatal period. Laboratory tests showed total bilirubin and direct bilirubin significantly increased with predominant increase of direct bilirubin. Total bile acid, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were also increased, while high-density lipoprotein cholesterol decreased. All patients were also accompanied by hepatosplenomegaly, with two of them having increased bronchovascular markings in chest X-ray. Two heterozygous changes of NPC1 gene, c.2741G>T +c.3020C>G (p. C914F + p. P1007R), c.2177G>C + c.3734_ 3735delCT (p.R726T + p. P1245RfsX12), and c.2054T>C + c.2128C>T(p.I685T + p.Q710X), were identified in patient 1, 2 and 3, respectively.

CONCLUSIONWe reported three cases suffered from Niemann-Pick disease type C with initial presentation as neonatal cholestasis in the mainland of China. For newborns with prolonged jaundice in the neonatal period, as well as neonatal cholestasis, hepatosplenomegaly, Niemann-Pick type C should be included in consideration of differential diagnosis. Genetic testing can identify causative mutations for diagnosis.

OBJECTIVETo study the effect of spleen lymphocytes on the splenomegaly by hepatocellular carcinoma-bearing mouse model.

METHODSCell counts, cell cycle distribution, the percentage of lymphocytes subsets and the levels of IL-2 were measured, and two-dimensional gel electrophoresis (2-DE) was used to investigate the relationship between spleen lymphocytes and splenomegaly in hepatocellular carcinoma-bearing mice.

RESULTSCompared with the normal group, the thymus was obviously atrophied and the spleen was significantly enlarged in the tumor-bearing group. Correlation study showed that the number of whole spleen cells was positively correlated with the splenic index. The cell diameter and cell-cycle phase distribution of splenocytes in the tumor-bearing group showed no significant difference compared to the normal group. The percentage of CD3+ T lymphocytes and CD8+ T lymphocytes in spleen and peripheral blood of tumor-bearing mice were substantially higher than that in the normal mice. Meanwhile, the IL-2 level was also higher in the tumor-bearing group than in the normal group. Furthermore, two dysregulated protein, β-actin and S100-A9 were identified in spleen lymphocytes from H22-bearing mice, which were closely related to cellular motility.

CONCLUSIONIt is suggested that dysregulated β-actin and S100-A9 can result in recirculating T lymphocytes trapped in the spleen, which may explain the underlying cause of splenomegaly in H22-bearing mice.

A 42-year-old Chinese man presented with left-sided chest pain and splenomegaly. Full blood count revealed erythrocytosis, while plain radiograph and computed tomography of the abdomen and pelvis revealed hepatosplenomegaly with splenic infarction. Further workup confirmed the diagnosis of polycythaemia vera. Clinical and imaging features of polycythaemia vera, as well as the potential pitfalls in image interpretation, are discussed in this article.

We recently encountered a case of hereditary spherocytosis coexisting with Gilbert's syndrome. Patient was initially diagnosed with Gilbert's syndrome and observed, but other findings suggestive of concurrent hemolysis, such as splenomegaly and gallstones were noted during the follow-up period. Therefore, further evaluations, including a peripheral blood smear, osmotic fragility test, autohemolysis test, and red blood cell membrane protein test were performed, and coexisting hereditary spherocytosis was diagnosed. Genotyping of the conjugation enzyme uridine diphosphate-glucuronosyltransferase was used to confirm Gilbert's syndrome. Because of the high prevalence rates and similar symptoms of these 2 diseases, hereditary spherocytosis can be masked in patients with Gilbert's syndrome. In review of a case and other article, the possibility of the coexistence of these 2 diseases should be considered, especially in patients with unconjugated hyperbilirubinemia who also have splenomegaly and gallstones.
