    The role of some adult flies (Diptera: Cyclorrhapha) as carriers of helminth parasites of man was studied at four sites in Malaysia: a refuse dump, where no helminth-positive flies were detected, and in three peri-domestic situations where four species of flies carried up to three types of nematodes. The dominant fly species Chrysomya megacephala (Fabricius) carried eggs of the roundworm Ascaris lumbricoides L., the pinworm Trichuris trichiura (L.) and hookworm on the adult external body surface and in the gut lumen, in association with Bukit Lanjan aborigines. Chrysomya rufifacies (Macquart) and Sarcophaga spp. also had Ascaris lumbricoides and Trichurus trichiura eggs in their gut contents. Human helminths were not recovered from Lispe leucospila (Wiedemann), Lucilia cuprina (Wiedemann) or the housefly Musca domestica L. In an urban slum area of Kuala Lumpur city, filariform larvae identified as the hookworm Necator americanus (Stiles) occurred in the intestines of the face-fly Musca sorbens Wiedemann (22 larvae per 100 flies) and of Chrysomya megacephala (4.5 larvae per 100 flies). This concentration of apparently infective N. americanus in M. sorbens, a fly which often breeds in faeces and browses on human skin, could have transmission potential.

    BACKGROUND: Previous studies have shown that serum VEGF levels were elevated in patients with active systemic lupus erythematosus (SLE), especially in those with lupus nephritis (LN). In this case control study, we aimed to compare serum levels of VEGF in SLE patients between LN, non-LN and healthy participants to determine the association between serum VEGF levels and the activity and histological classes of lupus nephritis.

    METHODS: Blood samples were obtained from 92 SLE patients (46 LN and 46 non-LN) and 26 controls. Data were collected from medical records. Serum VEGF assays were performed by specific, enzyme-linked immunosorbent assay kits (ELISA). Laboratory investigations included urinalysis, urine protein-creatinine ratio, serum creatinine, albumin and VEGF levels. Blood pressure, renal biopsy result and treatment were recorded. LN activity was evaluated using the renal subscale of the British Isles Lupus Assessment Group (rBILAG, 2004). The rBILAG measures blood pressure (diastolic and systolic), urine protein, serum creatinine, calculated glomerular filtration rate (GFR), presence of active urinary sediments and histological evidence of active nephritis.

    RESULTS: Serum VEGF was elevated in SLE patients with LN compared with the non-LN group and healthy controls. The levels found were significantly higher in the sera of patients with active nephritis compared to those with quiescent nephritis (P = 0.024). The study did not find a statistically significant relationship between serum VEGF levels and histological classes of LN.

    CONCLUSION: There was no significant difference of serum VEGF level between LN and non-LN SLE groups and between the non-LN group and healthy controls. However, there were increased levels of serum VEGF in the LN group, especially in patients with active nephritis as compared to quiescent nephritis group. This reflects the role of VEGF in the pathogenesis of lupus nephritis, however the clinical potential of this biomarker needs further study.
