105 sera from 101 patients with a confirmed diagnosis of dengue fever (LD) were examined using monospecific ELISA-IgM test. Monospecific results were observed in 39 samples (37.1%). 27 sample of them were taken during the first 7 days of the disease. In those systems were examined 23 serum samples of 23 patients, in which etiological role of one of the four dengue viruses was been established by the RT-PCR method. In this case, the coincidence-IgM ELISA results and the RT-PCR took place in 14 sera (60.9%).

In this work, a two-strain dengue model with vertical transmission in the mosquito population is considered. Although vertical transmission is often ignored in models of dengue fever, we show that effective control of an outbreak of dengue can depend on whether or not the vertical transmission is a significant mode of disease transmission. We model the effect of a control strategy aimed at reducing human-mosquito transmissions in an optimal control framework. As the likelihood of vertical transmission increases, outbreaks become more difficult and expensive to control. However, even for low levels of vertical transmission, the additional, uncontrolled, transmission from infected mosquito to eggs may undercut the effectiveness of any control function. This is of particular importance in regions where existing control policies may be effective and the endemic strain does not exhibit vertical transmission. If a novel strain that does exhibit vertical transmission invades, then existing, formerly effective, control policies may no longer be sufficient. Therefore, public health officials should pay more attention to the role of vertical transmission for more effective interventions and policy.

In presence of abnormal neurological features infective, immunological and metabolic etiologies are also needed to be kept as possibility. Dengue fever may present with variety of neurological manifestations. This case series includes rare neurological presentation of dengue fever including first ever reported case of dengue fever induced bilateral abducens nerve palsy with another case of dengue cerebellitis. This case series along with previous studies suggest that imaging may be normal in these cases. This case series also highlighted the possible immunological etio-pathogenesis and role of steroids as treatment modality.

Background: Thrombocytopenia is the hallmark laboratory finding in dengue fever and leads to bleeding manifestations when reduced markedly. So, this causes panic amongst the patient and relatives about the possibility of severity and leading to various complications including bleeding tendencies. Platelet transfusion is the only definitive treatment and it is indicated only in severe cases with bleeding manifestations. Prophylactic platelet transfusion is not much useful unless it’s reduced below 10,000cells/cumm. Carica papaya leaf extract (CPLE) are believed to have some role in improving platelets and its role is unclear. Hence, this study is taken up to evaluate the role of CPLE in improving dengue thrombocytopenia.Methods: Total 500 patients were included in the study; out of which 380 were males and 120 were females. Patients of dengue fever with thrombocytopenia (Platelet count <1, 50,000 cells/cumm) matching inclusion criteria were included in the study. After the inclusion, patients were randomized into two groups. Study group and control group by simple randomization (even/odd method). The study group treated with CPLE 1100mg three times daily for five days along with symptomatic and supportive treatment. The control group was given only symptomatic and supportive treatment. The average platelet count, average duration of stay and transfusion requirement of platelets were compared using student ‘t’ test.Results: Increased platelet counts were noted early in the treated group than the controlled group. The average duration of hospital stay was 5.42±0.98 days in study group and 7.2±0.97 days in controlled group. The requirement of platelets is more in control group than study group and it was statistically significant.Conclusions: Carica papaya leaf extract tablets can be used in patients with dengue thrombocytopenia with clear advantages over control group.

Aim: To evaluate the role of platelet parameters in dengue fever and also to determine relationship of platelet parameters with platelet count and the severity of the disease. The platelet para Materials and methods: meters [platelet count, plateletcrit, mean platelet volume (MPV), platelet distribution width (PDW)] of 50 dengue infected children were calculated using BC 3000 plus Mindray Automated Hematology Analyzer. Normal range of MPV is 7.5-11.5 . Plateletcrit cut off value in thrombocytopenia is 0.2-0.36%. The PDW reported varies with reference intervals ranging from 8.3 to 56.6%. Subjects were divided into four groups according to their platelet count on day 3 of illness (<20,000 cells/cumm, 20,000 to 50,000 cells/cumm, 50,000 to 100,000 cells/cumm and >100,000 cells/cumm). Platelet indices were studied among these groups and also the indices were evaluated with respect to the severity of disease as group A (dengue without warning signs), group B (dengue with warning signs and group C (severe dengue). Results: Male: female ratio was 28:22. Mean age of presentation was 7.8 + 2.2 years. Thirty-ve patients belonged to Group A, 26 to group B and 2 belonged to group C. PLT (cells/cumm) on Day 3 and Day 7 was 91,828 ±33,532 vs 195,371 + 70,586 in Group A patients (p<0.0001), 69,076 ±45,904 vs 163,230 + 85,053 in Group B patients (p=0.0018) 38,500 + 38,890 vs 86,000 + 28,284 in Group C patients (p=0.29). PCT (%) on Day 3 and Day 7 was 0.09 + 0.04 vs 0.18 + 0.06 in Group A patients (p<0.0001), 0.07 + 0.04 vs 0.15 + 0.07 in Group B patients (p=0.0009) and 0.04 + 0.04 vs 0.08 + 0.28 in Group C patients (p=0.84). MPV () on Day 3 and Day 7 was 10.73 + 1.07 vs 11.34 + 1.09 in Group A patients (p=0.0212), 10.41 + 1.39 vs 10.87 + 0.99 in Group B patients (p=0.3389), 9.35 + 1.62 vs 10.3±1.41 in Group C patients (p=0.59). PDW () on Day 3 and Day 7 was 14.46 ± 1.35 vs 13.22 + 1.10 in Group A patients (p=0.0001), 14.61 + 1.36 vs 13.0 + 0.76 in Group B patients (p=0.0011) and 14.5 + 1.84 vs 13.5 + 0.71 in Group C (p=0.54). Though MPV was lower in patients with platelet count <20,000 cells/cumm (8.57 + 0.5 ) as compared to other groups, it was not statistically signicant (p=0.325). PCT increases with increase in platelet count on Day 3 and Day 7 (p=0.000). Though PDW was lower on Day 3 in patients with platelet count <20,000 cells/cumm as compared to the other 3 groups, it was not statistically signicant (p=0.0740). Conclusion: Lower platelet count and low PCT are seen with severe dengue, increasing platelet count and PCT suggest recovery phase of dengue. MPV had no correlation with severity of dengue or level of thrombocytopenia suggestive that there is no role to predict severity of dengue. PDW does not uctuate with severity of dengue or level of thrombocytopenia
