A boy aged 11 years was admitted due to intermittent weakness and difficulty in walking for 6 years, and hepatomegaly, glycopenia and unconsciousness for 4 years. The laboratory examinations showed severe metabolic acidosis, hypoglycemia, and abnormal liver function. CT scan showed marked liver enlargement with fat density shadow. The boy was given fluid infusion, correction of acidosis, intravenous injection of glucose, L-carnitine, compound vitamin B, and coenzyme Q10, but he was in a persistent coma and it was difficult to correct refractory metabolic acidosis and hypoglycemia. The boy died. Blood and urinary organic acid screening and gene detection confirmed that the boy had late-onset glutaric aciduria type II (GAIIc) caused by electron-transferring-flavoprotein dehydrogenase (ETFDH) gene defect. GAIIc is an inherited metabolic disease with a low incidence, resulting in a high misdiagnosis rate. GAIIc should be considered for children with recurrent weakness or reduced activity endurance, hypoglycemia, and marked liver enlargement with abnormal liver function. Urinary organic acid analysis and blood tandem mass spectrometry can help with the early diagnosis of GAIIc, and ETFDH gene analysis helps to make a confirmed diagnosis.

A 2-year-old boy was admitted into the hospital because of cough and fever. Lymph node tuberculosis was noted when he was 2 months old and he was subsequently hospitalized several times because of cough and fever. After hospitalization the laboratory examination showed an increased eosinophia level in blood. The immune function tests shows decreased levels of IgG, IgA, and IgM. The patient had no response to anti-tuberculosis, anti-bacterial, and anti-fungal treatment, resulting in recurrent fever and progressive enlargement of the liver and spleen. Jam-like stools were noted 35 days after admission. B ultrasonography showed suspected intussusception. Laparotomy, reduction of intussusception and ileocecum angioplasty, biopsies of intestinal wall nodules and lymphoglandulae mesentericae, and hepatic biopsy were then performed under general anesthesia. The patient eventually died because of postoperative severe liver damage, disseminated intravascular coagulation and electrolyte disorder. Both the blood culture and hepatic biopsy tests showed Penicillium marneffei infecton. Immunodeficiency gene test was performed on the patient, his bother and their parents. T→G base substitution mutation (IVS1-3 T→G) in the CD40L gene was found in the patient. X-linked hyper-IgM syndrome was thus diagnosed in the patient. His mother was a carrier of the mutated CD40L gene, but his father was normal in the gene test. Hemizygous mutation in the CD40L gene was found in both the patient and his bother.

INTRODUCTIONThis study determined any clinical features which may help to differentiate biliary atresia (BA) from other causes of neonatal cholestasis (NC).

MATERIALS AND METHODSA prospective and observational study was conducted on consecutive infants with NC referred to the University of Malaya Medical Centre, Malaysia, between November 1996 and May 2004.

RESULTSThe 3 most common causes of cholestasis among the 146 infants with NC studied were idiopathic neonatal hepatitis (n = 63, 43%), BA (n = 35, 24%) and congenital cytomegalovirus hepatitis (n = 13, 9%). Common clinical features at presentation were jaundice (100%), hepatomegaly (95%), splenomegaly (52%) and pale stools (47%). Three clinical features noted to be sensitive for BA were the presence of acholic or variably acholic stools on admission, a liver which was firm/hard in consistency and a palpable liver of ≥4 cm (sensitivity of 77%, 80% and 94%, respectively), but the corresponding specificity was poor (51%, 65% and 39%, respectively). The stools of 2 children with BA were pigmented initially but became acholic subsequently.

CONCLUSIONSWe did not find any single clinical feature with sufficient sensitivity and specificity to differentiate BA from other causes of NC. Repeated inspection of stools colour is necessary as occasionally, patients with BA may have initial pigmented stools. Biochemical assessment and imaging studies are important in the assessment of any infant with NC.

OBJECTIVES: To investigate the clinical manifestations and laboratory examination results of children with Kawasaki disease complicated by macrophage activation syndrome (KD-MAS), and to provide a basis for identifying early warning indicators for the early diagnosis and treatment of KD-MAS. METHODS: A retrospective study was performed on 27 children with KD-MAS (KD-MAS group) and 110 children with KD (KD group) who were admitted to Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2014 to January 2022. Clinical and laboratory data were compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the value of laboratory markers with statistical significance in the diagnosis of KD-MAS. RESULTS: Compared with the KD group, the KD-MAS group had significantly higher incidence rates of hepatomegaly, splenomegaly, incomplete KD, no response to intravenous immunoglobulin, coronary artery damage, multiple organ damage, and KD recurrence, as well as a significantly longer length of hospital stay (P<0.05). Compared with the KD group, the KD-MAS group had significantly lower levels of white blood cell count, absolute neutrophil count, hemoglobin, platelet count (PLT), erythrocyte sedimentation rate, serum albumin, serum sodium, prealbumin, and fibrinogen (FIB), a significantly lower incidence rate of non-exudative conjunctiva, and significantly higher levels of C-reactive protein, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase (LDH), and serum ferritin (SF) (P<0.05). The ROC curve analysis showed that SF, PLT, FIB, and LDH had high value in the diagnosis of KD-MAS, with areas under the curve (AUC) of 0.989, 0.966, 0.932, and 0.897, respectively (P<0.001), and optimal cut-off values of 349.95 μg/L, 159×10⁹/L, 3.85 g/L, and 403.50 U/L, respectively. The combination of SF, PLT, FIB, and LDH had a larger AUC than PLT, FIB, and LDH alone in the diagnosis of KD-MAS (P<0.05), but there was no significant difference in the AUC between the combination of SF, PLT, FIB, and LDH and SF alone (P>0.05). CONCLUSIONS KD-MAS should be considered when children with KD have hepatosplenomegaly, no response to intravenous immunoglobulin, coronary artery damage, and KD recurrence during treatment. SF, PLT, FIB, and LDH are of high value in the diagnosis of KD-MAS, especially SF is of great significance in the diagnosis of KD-MAS.

Hepatitis A is generally known as a mild, self-limiting disease of the liver, but in rare instances it can progress to fulminant hepatitis, which may require liver transplantation for recovery. Such cases are known to be related to old age and underlying liver disease. We report four cases of hepatitis A in which patients presented with fulminant hepatitis and acute renal failure and underwent liver transplantation. The following common features were observed in our cases: (1) occurrence in relatively old age (> or =39 years old), (2) association with acute renal failure, (3) presence of hepatomegaly, and (4) microscopic features of submassive hepatic necrosis.

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.
