A monophosphoryl lipid A (MPLA) derivative having the 6'-OH group substituted with an NH2 group was synthesized and coupled with the upstream terminal tetrasaccharide of mycobacterial lipoarabinomannan (LAM) via an amide bond to create a novel type of MPLA-based fully synthetic glycoconjugate vaccine. The same tetrasaccharide was also coupled with MPLA at the 1-O-position. Immunological activities of the two synthetic conjugates were evaluated in mice and compared. Both provoked robust overall and IgG antibody responses, but intraperitoneal injection elicited significantly stronger responses than subcutaneous injection...

Although generally rising in incidence, intestinal tuberculosis is still rare in western countries and due to unspecific manifestations mainly as ulcerations on endoscopy, diagnosis of intestinal tuberculosis is challenging. Within this report, we describe a case of severe intestinal tuberculosis radiologically and endoscopically masquerading as colorectal cancer with peritoneal carcinomatosis. Our case exemplifies that intestinal tuberculosis needs to be considered as a differential diagnosis in patients at risk and that undelayed and sensitive diagnosis of intestinal tuberculosis is of central importance for avoiding unfavorable disease outcome...

The remarkable ability of M. tuberculosis ( Mtb ) to survive inside the human macrophages is attributed to the presence of a complex sensory and regulatory network. PrrA is a DNA-binding regulatory protein, belongs to an essential two-component system (TCS), PrrA/B; which is required for early phase intracellular replication of Mtb. Despite its importance, the mechanism of PrrA/B-mediated signaling is not well understood. Here, we demonstrate that the binding of PrrA on the promoter DNA and its consequent activation is cumulatively controlled via dual phosphorylation of the protein...

Mycobacterium tuberculosis is a highly virulent bacterium that causes tuberculosis. It infects about one third of the world's population. Type I interferons (IFNs) play a detrimental role in host defense against M. tuberculosis infection. Proteins secreted by M. tuberculosis through ESX-1 secretion system contribute to type I IFNs production. However, the precise mechanism by which 6-kDa early secretory antigen target (ESAT6), one of ESX-1-mediated secretory proteins, induces type I IFNs production in host cells is currently unclear...

Myeloperoxidase (MOP) is present in monocyte and neutrophil lysosomes, catalyzing hydrogen peroxide and chloride ion conversion to hypochlorous acid. MOP seems to destroy pathogens during phagocytosis by neutrophils and is considered an important defense against innumerous bacteria. We present a patient who had MOP deficiency, who presented with a subacute form of paracoccidioidomycosis and later with peritoneal tuberculosis. MOP deficiency leads to the diminished destruction of phagocytized pathogens. This case gives important evidence of an association between MOP deficiency and increased susceptibility to infection by Paracoccidioides brasiliensis and Mycobacterium tuberculosis...

Abdominal tuberculosis (TB) may affect any part of the gastrointestinal tract resulting in significant morbidity and mortality. There is an increase in the incidence of abdominal TB favored by the emergence of multi-drug resistant Mycobacterium tuberculosis and immunosuppression especially from HIV co-infection. Our case is that of a 31 year old HIV-positive woman, adherent to antiretroviral therapy, who presented with a 2 month history of progressive abdominal distention, drenching night sweat and fatigue, but without fever...

A 59-year-old Portuguese Caucasian man with a history of heavy alcohol intake and no significant medical history presented with ascites, weight loss and general malaise. The ascitic fluid analysis showed 921 cells/mm(3) with mononuclear predominance (93.6%), elevated total proteins and a slightly elevated serum-ascites albumin gradient. The abdominal ultrasound confirmed the presence of chronic liver disease with ascites, and additionally on CT there was evidence of peritoneal thickening. On repeat paracentesis, the ascitic fluid analysis showed elevated adenosine deaminase but it was negative for the presence of mycobacteria by Ziehl-Neelsen stain, Löwenstein-Jensen culture and PCR amplification...

Scrotales fistulas are rare and often represent secondary lesions of tuberculosis. Mucinous adenocarcinomas are tumors containing at least 50% of extracellular mucus. They occur most commonly in the rectosigmoid; scrotal location is rare. We report the case of a 54-year old patient, with no particular past medical history, with secondary mucinous adenocarcinoma of the scrotum revealed by scrotal fistulas. The patient had suffered from recurrent scrotal fistulas for two years, with no other associated signs...

Tuberculosis is a systemic disease which involves skeletal and articular system very rarely. Osteoarticular tuberculosis commonly occurs in the vertebral column and more rarely in the sacroiliac joints. In this study, we report a 44-years-old male patient with low-grade fever, malabsorption syndrome, abdominal and pelvic ascites and low-back pain, that underwent (18)F-FDG PET/CT for identifying the cause of signs and symptoms after a negative abdominal CT and negative thorax radiography. The study revealed increased tracer uptake at the peritoneal ascites and at the right sacroiliac joint in absence of bone alteration suggesting a sacroiliitis...

BACKGROUND: Vitamin D is recognised to have multiple actions, including role in immune modulation. The prevalence and impact of vitamin D deficiency (VDD) in abdominal tuberculosis is unknown. METHODS: We report the prevalence and clinical impact of VDD in patients with abdominal tuberculosis. The patients were divided into two groups: VDD (<20 ng/ml) or vitamin D sufficient (VDS) (⩾20 ng/ml). Groups were compared for extent (abdominal alone or extra-abdominal also) of disease and pattern of involvement (intestinal, peritoneal or both) and inflammatory response [serum C-reactive protein (CRP)]...

Tuberculosis (TC) is very common and significant cause of morbidity and mortality worldwide. Isolated cystic duct lymph node TC cases without involvement of gallbladder are exceedingly rare. It is difficult to diagnose preoperatively because of lack of characteristic signs and symptoms of TC. We report a man aged 45 years who presented with right upper abdominal pain since 1week. It was associated with nausea and postprandial fullness. There was no evidence of jaundice and lymphadenopathy. Abdominal examination showed moderate right upper quadrant tenderness with positive Murphy's sign and splenomegaly but no signs of peritonism...
