Multidrug-resistant IgA Vasculitis with Gastrointestinal Symptoms Successfully Treated with Intravenous Cyclophosphamide and Maintained with Mycophenolate Mofetil.

We present the case of a 17-year-old woman with IgA vasculitis (IgAV) who presented with relapsing gastrointestinal (GI) symptoms that were refractory to glucocorticoid and combination therapy with cyclosporine A, azathioprine or mycophenolate mofetil (MMF). The patient responded well to remission induction with intravenous cyclophosphamide (IVCY) and was successfully maintained with MMF. Remission induction with IVCY followed by maintenance therapy with MMF was effective in a patient with multidrug-resistant IgAV with GI lesions.

Chronic Diarrhea: A rare presentation of Hodgkin's Lymphoma.

Hodgkin's Lymphoma is a cancer affecting the lymphatic system. There are two subtypes of Hodgkin's Lymphoma: Nodular lymphocyte predominant (NLPHL) and classical Hodgkin's Lymphoma which has further four types. It has a bimodal distribution and is more common among males. The most common presentation is painless swelling in the neck, armpit or groin region. Associated Symptoms include night sweats, unintentional weight loss, fever, persistent cough or dyspnea. Involvement of the gastrointestinal tract is a rare occurrence. Diagnosis is based on hematological, radiological and histochemical studies. Here we report a rare presentation of a 47-year-old male who presented with symptoms of loose stools, weight loss and fever. CT scan and abdominal lymph node biopsy findings were consistent with a lymphoproliferative disorder Patient was being managed in the line of malabsorption syndrome with possible underlying malignancy but his condition deterioted before the histological diagnosis was confirmed. Thus, this report highlights the importance having a consideration for Hodgkin's lymphoma in the management of chronic diarrhea.

Association between the -174 C/G polymorphism in the interleukin-6 (IL-6) gene and gastrointestinal involvement in patients with systemic sclerosis.

Genetic predisposition to systemic sclerosis (SSc) has still not been fully revealed. Interleukin-6 (IL-6) is a mediator of T cell proliferation and fibrotic events in SSc. Polymorphisms in the IL-6 are found to be important in susceptibility to development of SSc. We aimed to assess the frequency of -174 C/G of IL-6 gene polymorphism in SSc patients and healthy controls, as well as correlation with disease manifestations. In the case-control study, 102 patients with SSc and 93 controls were included. PCR-RFLP method was performed for genotyping promotor variants -174 C/G of IL-6 gene. The expression level of IL-6 was determined by qRT-PCR on subset of 50 patients and 13 healthy controls with different IL-6 genotypes. We used UCLA GIT 2.0 questionnaire to assess gastrointestinal involvement in SSc patients. The expression level of IL-6 gene was significantly higher in patients with SSc in comparison with healthy controls (p < 0.05). Carriers of C-allele of IL-6 gene compared to those with G allele, showed higher expression of IL-6 gene (95.8 vs. 41.2, p < 0.05), higher GIT total score (0.85 vs. 0.5, p < 0.05) and higher distension scale score (1.4 ± 0.9 vs. 0.78 ± 0.8, p = 0.05). No significant differences in genotype distribution and allele frequency were observed between patients and controls. The expression of IL6 gene varies significantly during the course of SSc. The IL-6 gene variant -174 C/G (presence of C-allele) is associated with higher IL-6 gene expression and greater GIT impairment in patients with SSc.

Validation of Serbian version of UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Tract Instrument in 104 patients with systemic sclerosis.

Gastrointestinal (GI) involvement is the leading cause of morbidity with great impact on health-related quality of life (HRQOL) in patients with systemic sclerosis (SSc). The UCLA-GIT 2.0 is a disease-specific HRQOL instrument for the assessment of GI symptoms severity in patients with SSc. We evaluated reliability and validity of the Serbian version of UCLA-GIT 2.0 by assessing association of GI involvement and other disease manifestations in patients with SSc. UCLA-GIT 2.0 was adapted into Serbian and administered to 104 patients with SSc who had previously completed the SF-36 questionnaire. We evaluated the internal consistency reliability and associations between the UCLA-GIT 2.0 and SF-36 scales. Data from patients' medical history were reviewed for other disease manifestations. UCLA-GIT 2.0 had acceptable reliability (defined as Cronbach's alpha >0 .69) and the majority of hypothesized correlations with SF-36 scale scores were of moderate magnitude (coefficient ≥ 0.30). Active disease and pulmonary fibrosis were associated with higher GIT Total scale score (p < 0.05). Distension mostly correlated with HRQOL impairment (r = 0.70, p < 0.001). The Serbian version of the UCLA-GIT 2.0 questionnaire has acceptable reliability and validity for the assessment of GI involvement in patients with SSc. GI impairment is very frequent in patients with active SSc, as well in those with pulmonary fibrosis.
