The TBARS level was significantly more in complicated falciparum malaria patients (4.2 +/- 1.03 nmol/ml) than uncomplicated falciparum malaria patients (2.01 +/- 0.61 nmol/ml).

Standard methods like indirect immunofluorescence (IIF) microscopy along with Confocal microscopy and ELISA were used for identifying and quantifying the autoantibodies and IIF patterns on PMN and HL-60 cells were studied for ANCA classification. Also HEp-2 cells were used for ANA detection, while estimation of anti-dsDNA, AHA, anti-MPO, anti-PR3 and anti-LF were tested using ELISA. Sera from malaria patients showed prominent immunofluorescence staining patterns where 23.8% cases had ANA in P. falciparum group as compared to 15.4% in P. vivax group and ANCA was found to be present in 20% in P. falciparum and 15.4% in P. vivax group. An interesting observation was that, of the total ANCA positives, 59% had p-ANCA, 5.9% had c-ANCA and 44.1% of the cases showed the 'atypical' or X-ANCA pattern. When p-ANCA positivity was compared with c-ANCA positivity among these patients, a good statistical correlation was noted with OR = 16, chi 2 = 16.43, EF = 0.46 and p-value = 5.037E 0.5. ELISA showed 31.2% anti-MPO and 6.2% anti-PR3 in P. falciparum cases while the two ANCA positive cases in P. vivax had anti-MPO. Anti-LF was found to be present in 40.6% cases. Neither the P. falciparum nor P. vivax contained autoantibodies with specificities similar to the characteristic lupus autoantibodies such as double stranded DNA (dsDNA). ANCA positivity develops in some types of malarial infection also with the presence of various autoantibodies which is important from a clinical point of view and should be carefully evaluated in those geographic areas where malaria is endemic. It also alerts us to the fact, whether in cases of repeated malarial infections in susceptible individuals, vasculitic disorders, which through ANCA pathways develop, could lead to renal and other complications.</p>","PeriodicalId":77174,"journal":{"name":"Indian journal of malariology","volume":"39 3-4","pages":"51-9"},"PeriodicalIF":0.0,"publicationDate":"2002-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24132744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Entomological evaluation revealed that jute curtains treated with alphacypermethrin in Slum-I resulted drastic reduction in daytime indoor resting mosquitoes such as An. stephensi, Ae. aegypti and Cx. quinquefasciatus. Similarly, malaria incidence also reduced in the treated curtain used area when compared to that of in untreated curtain and without curtain areas. Bioassay tests on An. stephensi and Cx. quinquefasciatus showed that alphacypermethrin could produce > 70 per cent mortality up to six months in case of An. stephensi--a principal urban malaria vector and hence two rounds of treatment are sufficient in an year to protect inhabitants from malaria.

Blood examinations for malaria parasites, Plasmodium falciparum specific-IgG concentration and serological reactivity with P. falciparum-histidine rich protein-2 (HRP-2) antigens were conducted on all the pregnant women during the dry and rainy seasons of the year. During the dry season, 109 (74%) of the recruited pregnant women without symptoms had P. falciparum parasitaemia, while 79 (80%) of the recruited pregnant women without symptoms had P. falciparum parasitaemia during the rainy season. However, the P. falciparum malaria parasites density was significantly raised during the dry season compared with that of in the rainy season (p < 0.05). Serological analysis with P. falciparum histidine rich protein-2 antigen (HRP-2) showed 108 (73%) and 71 (77%) of the pregnant women without symptoms as seropositive during the dry and rainy seasons respectively. The P. falciparum specific-IgG concentration was similar during both seasons in the HRP-2 seropositive pregnant women without symptoms (p > 0.05). The results showed no seasonal tide in the incidences of asymptomatic P. falciparum parasitaemia; however, the significantly raised parasitaemia during the dry season may suggest possible increased parasites tolerance.
