Syphilis in pregnancy

Syphilis in pregnancy remains an important medical condition due to its consequences. We present two cases of young pregnant women who were diagnosed syphilis during their antenatal visit. The first case was a 29-year-old Malay lady diagnosed with syphilis during the first trimester of pregnancy, while the second case was a 21-year-old Chinese lady diagnosed with syphilis during the third trimester of pregnancy. The diagnosis and management of the syphilis in pregnancy are discussed

Anti-cyclic citrullinated peptide antibody is a good indicator for the diagnosis of rheumatoid arthritis

Anti-cyclic citrullinated peptide [CCP] antibody has recently been used in the classification of rheumatoid arthritis [RA]. This antibody is more specific than rheumatoid factor [RF] for the diagnosis of RA. The study objectives were to determine the sensitivity, specificity, positive and negative predictive values of anti-CCP in RA diagnosis. Eighty RA patients and 80 non-RA individuals were included in the study. Blood was collected from both arms of study subjects and tested for anti-CCP and RF antibodies. Relevant clinical information and laboratory profiles of the RA patients were evaluated using patients' medical records and Integrated Laboratory Management System [ILMS], respectively. The sensitivity and specificity of anti-CCP were 35% and 100% respectively. The positive and negative predictive values were 100% and 61%, respectively. Positive anti-CCP was found significantly associated with multiple joint pain [p < 0.001] and hand's joints pain [p=0.01], symmetrical joints involvement [p=0.015] and high CRP value [p < 0.001]. Anti-CCP was also found to have positive association with RF [p < 0.001]. Anti-CCP is highly specific for the diagnosis of RA. High positive predictive value should be taken into consideration for effective treatment

Case series of syphilis and HIV co-infections

Syphilis and HIV co-infection are indeed dangerous combinations. The present communication describes three different cases of syphilis and HIV co-infection in young men. The first case is a 25-year-old medical graduate with a primary and secondary syphilis lesions at time of presentation. The second case is a 24-year-old government officer with right eye posterior uveitis where the serology tests for syphilis were reactive. His HIV tests were also positive. The final case is a 25-year-old homosexual who was admitted to the medical ward because of Mycobacterium tuberculosis infection. The HIV and syphilis serology tests were noted to be positive

Immunofluorescence (IF) Pattern, Autoantigens of Anti-neutrophil Cytoplasmic Antibodies (ANCA) and Their Clinical Associations / Jurnal Sains Kesihatan Malaysia

Antineutrophil cytoplasmic antibodies (ANCA) are autoantibodies directed against primary granules of neutrophils and monocytes’ lysosomes. In general, c-ANCA is strongly associated with vasculitic disorders mainly in ANCA-associated systemic vasculitis (AASV). p-ANCA have been identified in several diseases such as primary (AASV) and secondary vasculitis such as collagen vascular diseases, rheumatoid arthritis and inflammatory bowel diseases given the term ‘ANCA-associated disease.’ The objective of this study was to determine the rate of ANCA positivity by indirect immunofluorescent (IF) and enzyme linked immunosorbent assay (ELISA) and its association with AASV and ANCA associated diseases. Serum from patients with history suspicion of systemic vasculitis were tested for ANCA by IF. Those samples positive for ANCA by IF were further tested for antibodies against myeloperoxidase (MPO) and proteinase 3 (PR3) using the ELISA. Clinical data from medical records were obtained and analyzed. Of 468 samples, a total of 110 were positive for ANCA by IF. IF results showed a p-ANCA pattern in 96 patients and c-ANCA in 14. Of 110 IF positive ANCA, 45 patients were positive by ELISA. Seventeen were positive for MPO-ANCA, 9 were PR3-ANCA positive and 19 were both MPO and PR3 positive. Only 2 patients were classified AASV ie Wegener granulomatosis and the other with microscopic polyangiitis. The remaining patients (n = 108) may be classified as ANCA associated diseases. Our study showed that p-ANCA (87.3%) was the more common ANCA pattern and 40.9% of IF positive samples were positive for PR3- and MPOANCA.
