Intestinal tuberculosis: Case series of three patients

Abstract: Background Intestinal tuberculosis (ITB) is a fraction of extrapulmonary TB, and its diagnosis often pose a significant challenge due to nonspecific presentation. Several methods have been utilized to diagnosed ITB, including findings of specific inflammatory process on histopathological examination. We hereby report three cases of ITB that manifested as caecal and adnexal mass. Case report First case, a 22-year-old male, presenting with abdominal pain, underwent exploratory laparotomy, biopsy, right hemicolectomy, and anastomosis end-to-side to the transverse ileocolical region due to partial ileus obstruction from caecal tumor. The second and third cases, a 27-year-old and 39-year-old females, both presenting with abdominal pain and distension, underwent exploratory laparotomy, adhesiolysis and biopsy. Histopathological examination in all three cases showed chronic granulomatous inflammation caused by TB. All three patients were diagnosed as ITB and received 6 months of anti-tuberculosis drug (ATD). Discussion Intestinal TB most commonly affected region is the ileocaecal, accounts for 64% of the incidence of gastrointestinal TB. The main reasons for the predilection of ileocaecal region are due to relatively longer faecal static, the abundant of lymphoid tissue, a neutral pH environment and absorptive transport mechanisms that allow swallowed mycobacterium to be absorbed. Intestinal TB may pose similar symptoms as those found in pulmonary TB, yet patients most commonly presenting with abdominal pain. Bacteriological signs and histopathological findings are gold standard for ITB diagnosis. Therapy for ITB includes pharmacological ATD and surgical therapy.

Sccmec type II gene is common among clinical isolates of methicillin-resistant Staphylococcus aureus in Jakarta, Indonesia

Abstract: Community Acquired Methicillin Resistant Staphylococcus aureus (CA-MRSA) is a strain of MRSA that can cause infections in patients in the community, in which these patients had no previous risk factors for MRSA infection and the patient received 72 hours prior to infection when admitted to hospital. This study aims to determine and compare the characteristics of epidemiological, clinical, and molecular biology of CA-MRSA with HA-MRSA. A total of 11 clinical strains of Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Stapylococcus aureus (MSSA) were collected from 2 hospitals in Jakarta, Indonesia in 2012. SCCmec typing was performed by multiplex polymerase chain reaction (PCR) and the presence of six genes (vraR, vraG, vraA, vraF,fruA, and fruB) associated with vancomycin resistance was examined by simple PCR analysis. We found three strains of community-acquired MRSA with SCCmec type II and one strain of hospital-acquired MRSA with SCCmec type IV. The other seven strains did not contain mecA genes and SCCmec. Plasmid pUB110 was found in one strain of community-acquired MRSA and two strains of hospital-acquired MRSA. vraA genes were present in 9 of the 11 strains, vraF in 4, vraG in 5, and vraR in 4. Note worthily, three quarters of strains without pUB110 contained vraR and vraF, and 70% contained vraA, whereas 60% of strains with pUB110 contained vraG. Based on these results, we should be concerned about the possibility of transition from MRSA strains sensitive to vancomycin in VISA strains of MRSA strains obtained in clinical trials. But first we need to look the existence of natural VISA or hVISA among these MRSA strains.

Expression of interleukin-8, interleukin-10 and Epstein-Barr viral-load as prognostic indicator in nasopharyngeal carcinoma.

Abstract: Interleukin-8 (IL-8) is angiogeneic chemokine that plays a potential role in both development and progression of many human malignancies including nasopharyngeal carcinoma (NPC). Epstein- Barr virus (EBV) is recognized to be an important etiologic agent of NPC as the viral gene products are frequently detected in NPC tissue along with the elevation of antibody titre to the viral protein (VCA-p18+ EBNA1) of IgA in the majority of patients. Elevated plasma of Viral Load is regarded as an important marker for the presence of the disease and for the monitoring of disease progression. However, other serum /plasma parameters such as the level of certain interleukins (IL-8 and IL-10) has also been implicated in NPC progression. The study aimed to investigate the correlations between plasma Viral Load and the level of interleukin (IL-8) and Interleukin (IL-10) in relating these parameters to the stages of NPC. In addition of Viral Load (VCA-p18+EBNA1) IgA, Interleukin-8 and Interleukin-10 before and after therapy will be investigated to seek the possible marker for disease progression. A total of 39 NPC patients and 29 healthy control individuals enrolled in this study. Plasma Viral Load was quantified using real-time quantitative PCR. The Level of plasma interleukins both IL-8 and IL-10 were analyzed using ELISA methods. Results indicated there was a significant decrease in viral load was detected in plasma of NPC patients following therapy. Plasma of viral load was shown to be a good prognosticator for disease progression. There were positive correlation between plasma of viral load and IL-8. These non invasive parameters expressed in blood, could be substitutes of viral load using brushing method, which is invasive. In conclusion that: Viral Load, (VCA-p18+EBNA1) IgA and IL-8 levels are promising markers for the presence of NPC and progression of the disease.

Protective effects of Phaseolus vulgaris lectin against viral infection in Drosophila.

Abstract: Phytohemagglutinin (PHA) isolated from the family of Phaseolus vulgaris beans is a promising agent against viral infection; however, it has not yet been demonstrated in vivo. We herein investigated this issue using Drosophila as a host. Adult flies were fed lectin approximately 12 h before they were subjected to a systemic viral infection. After a fatal infection with Drosophila C virus, death was delayed and survival was longer in flies fed PHA-P, a mixture of L4, L3E1, and L2E2, than in control unfed flies. We then examined PHA-L4, anticipating subunit L as the active form, and confirmed the protective effects of this lectin at markedly lower concentrations than PHA-P. In both experiments, lectin feeding reduced the viral load prior to the onset of fly death. Furthermore, we found a dramatic increase in the levels of the mRNAs of phagocytosis receptors in flies after feeding with PHA-L4 while a change in the levels of the mRNAs of antimicrobial peptides was marginal. We concluded that P. vulgaris PHA protects Drosophila against viral infection by augmenting the level of host immunity.
