Antibody and memory B cell responses to the dengue virus NS1 antigen in individuals with varying severity of past infection

To further understand the role of NS1-specific antibodies (Abs) in disease pathogenesis, we compared neutralizing antibody levels (Nabs), NS1-Ab levels, IgG antibody subclass profiles and NS1-specific memory B-cell responses (Bmems) in individuals, with varying severity of past dengue. Nabs (Neut50 titres) were assessed using the Foci Reduction Neutralization Test (FRNT) and in-house ELISAs were used to assess NS1-Abs and NS1-Ab subclasses for all four DENV serotypes in individuals with past DF (n = 22), those with past DHF (n = 14) and seronegative (SN) individuals (n = 7). B-cell ELISpot assays were used to assess NS1-specific Bmem responses. 15/22 (68.18%) individuals with past DF and 9/14 (64.29%) individuals with past DHF had heterotypic infections. Neut50 titres were found to be significantly higher for DENV1 than DENV2 (p = 0.0006) and DENV4 (p = 0.0127), in those with past DHF, whereas there was no significant difference seen in titres for different DENV serotypes in those with past DF. Overall NS1-Ab to all serotypes and NS1-specific IgG1 responses for DENV1, 2 and 4 serotypes were significantly higher in those with past DHF than individuals with past DF. Those with past DHF also had higher IgG1 than IgG3 for DENV1 and DENV3, whereas no differences were seen in those with past DF. Over 50% of those with past DF or DHF had NS1-specific Bmem responses to >2 DENV serotypes. There was no difference in the frequency of Bmem responses to any of the DENV serotypes between individuals with past DF and DHF. Although the frequency of Bmem responses to DENV1 correlated with DENV1-specific NS1-Abs levels (Spearman r = 0.35, p = 0.02), there was no correlation with other DENV serotypes. We found that those with past DF had broadly cross-reactive Nabs, while those with past DHF had higher NS1-Ab responses possibly with a different functionality profile than those with past DF. Therefore, it would be important to further evaluate the functionality of NS1-specific antibody and Bmem responses to find out the type of antibody repertoire that is associated with protection against severe disease.

Clinical characteristics of haemorrhagic fever with renal syndrome in children

From January 1988 to September 1989, seven patients (4 girls and 3 boys, aged 3–12 years) with haemorrhagic fever with renal syndrome (HFRS) were hospitalised at the University Children's Hospital in Belgrade. In four patients the disease appeared as a family outbreak, the others were sporadic cases. In six patients the clinical presentation was suggestive of HFRS, as they had fever with headache, myalgia, sore throat and gastrointestinal illness followed by renal abnormalities. However, severe haemorrhagic syndrome with petechia, haematoma, haematemesis and melaena was present in one patient only. Renal disease presented as nephritic syndrome and/or acute renal failure. Five patients recovered after 2–3 weeks without sequellae, one patient had decreased renal function 17 months after the start of the disease and the remaining patient died. In six patients the diagnosis of HFRS was confirmed serologically by a significant rise in antibody titres against hantaviruses, while in the patient with the fatal and fulminant course of the disease, the diagnosis was established on the basis of epidemiological and autopsy findings. We suggest that children living in endemic areas who develop an ill-defined, febrile and gastrointestinal disease with renal dysfunction should be evaluated for HFRS.     

Chronic hematuria and localized bladder damage following combined cyclophosphamide and local radiotherapy.

A 13-year-old white male had Ewing sarcoma of the right pubic and ischial bones. Initial therapy consisted of 5,400 rads in seven weeks to the right side of the pelvis and 14 intravenous injections of cyclophosphamide (Cytoxan, CTX) at 500 mg/m2; BCNU and Adriamycin maintenance therapy continued for a total of two years. He has now been disease-free for five years. Three months following the completion of the right pelvic radiotherapy (RT), while on intravenous CTX, severe hematuria appeared, which subsided, but at present he has continuous microscopic hematuria, as well as periodic episodes of gross hematuria. Serial cystocopies initially revealed thickening and hemorrhagic and edematous changes on the right (irradiated) side of the bladder, and recent multiple telangiectatic patches have been demonstrated as a late "healing" phase. This case demonstrates the additive toxicity to the bladder of CTX and RT, illustrating that the hemorrhagic cystitis can be extremely protracted lasting five years.     

Infant influenza

Reports on the symptoms of infant influenza (less than 1 year of age) are very few. From 1989 to 1996, 105 infants with influenza were examined. The symptoms, nutrition and source of infection of the 105 patients were investigated in Sakuma Pediatric Clinic and viral studies were performed at the Kitakyushu City Institute of Environmental Sciences. The symptoms of patients under 6 months old are very mild, with a low maximum body temperature and a short duration of fever. Other complications are few. The symptoms gradually become more severe with each month of age. The ratio of patients displaying a diphasic fever with two peak temperatures increases with each month of age. Over 50% of patients over 9 months old have this diphasic fever with two peak temperatures. It is inconclusive whether an anti-infective factor in human milk exists or not. Of the 105 patients in this study, 28 were under 4 months of age; of these 28, all but 3 were infected by family members.
