There is no sufficient laboratory test for the diagnosis of MDD and it is expected that this investigation may be helpful for better diagnosis and management of MDD. We aimed to measure serum immunoglobulin levels in MDD patients and control subjects to meet the above demand. Methods: For this purpose, we recruited 88 MDD patients from the department of psychiatry, Bangabandhu Sheikh Mujib Medical University, Dhaka and 89 healthy volunteers from Dhaka city matched with age, sex and socioeconomic status to the patient group. Turbidimetry method was applied to measure serum levels of immunoglobulin A, G, and M where immunoglobulin kit was utilized. Results: The current study revealed that mean serum concentrations of immunoglobulin A, G, and M in patients were found to be 209.07 ± 104.93, 791.50 ± 235.67 and 107.92 ± 47.53 mg/dL while those were 195.34 ± 92.16, 763.81 ± 175.89 and 99.17 ± 48.78 mg/dL in control subjects, respectively. Conclusion: Our result indicates that serum concentrations of immunoglobulin A, G and M were not significant between the groups and further studies are required to establish these findings.展开更多

The purpose of this chart review was to assess safety and clinical outcomes of SBI in refractory irritable bowel syndrome (IBS) patients. Methods: A retrospective review of 35 IBS patients with diarrhea or mixed diarrhea/constipation pattern (IBS-M) who were administered SBI 5 grams twice daily was performed. Clinical response (“good response” or “no response”) and adverse events were determined by follow-up after four weeks of therapy. Patients were included for evaluation if a lactulose breath test (LBT) had been performed prior to SBI. All patients were refractory to common IBS therapies. The response rate to the inclusion of SBI was calculated in three separate groups: dividing patients based on their LBT results (positive or negative), dividing patients by their IBS diagnosis (IBS-D or IBS-M) and grouping all patients together. Results: Analysis was carried out on 26 IBS-D/-M patients with LBT results. Two patients were lost to follow-up and were excluded from data analysis. The positive LBT group (N = 11) had a 73% (p = 0.117) positive response rate to SBI. The negative LBT group (N = 13) had a significant response rate of 77% (p = 0.040). If patients were divided by IBS diagnosis or grouped together, the response rate to SBI was similarly ranging from 69% - 88%. Adverse events leading to cessation of SBI occurred in 3 of 24 patients. Conclusion: SBI appeared to be a safe and effective nutritional moiety in refractory IBS-D and IBS-M patients. Larger, double-blind studies are needed.展开更多

Methods: Patients in this case series were chosen based on their lack of satisfactory response to a variety of drugs, including antidiarrheal and antispasmodic medications, serotonin 5-HT3 receptor antagonists, selective serotonin re-uptake inhibitors (SSRIs), proton pump inhibitors (PPIs), antibiotics, and antidepressive drugs. Patients met Rome III criteria and were administered 5 g/day of SBI as standard-of-care nutritional support. A scale of 0% - 25%, 25% - 50%, 50% - 75%, 75% - 100% response to SBI was used for patient-reported improvement in overall IBS symptoms following administration for one month. Exact methods for calculating confidence intervals and p-values were used to assess complete management of symptoms and response to therapy. Adverse events were also monitored for this nutritional product. Results: The onset of gastrointestinal (GI) symptom reduction utilizing nutritional management with SBI occurred within an average time of 2-4 weeks with improved or near complete management in all 10 patients who were refractory to previous drug therapies by 4 weeks. When prompted, patients reported significant IBS symptom improvement which averaged between 50% - 100% (p = 0.002) with an average for complete management in all patients of 69%. No side effects were reported after SBI administration even when taken for up to 28 weeks. Conclusion: Based on the safety profile and reported outcomes in this case report, SBI should be considered as a nutritional option for management in IBS-D and IBS-U.展开更多

Methods: This is a cross sectional study. Patients with oro-facial squamous cell carcinoma attending the Oral Pathology and Radiotherapy clinics of the University College Hospital, Ibadan, Nigeria were included. Seventy subjects comprising 22 patients with untreated OSCC, 18 patients with OSCC receiving treatment and 30 healthy, age and gender matched individuals were included. Serum and salivary samples from the participants were analysed for IgA levels using ELISA technique. Results: The mean value of serum IgA in OSCC patients receiving treatment was significantly lower compared with healthy controls (p = 0.03), while no significant difference was observed comparing untreated OSCC patients with treated and healthy controls. The salivary IgA levels did not show any significant difference between the three groups (p = 0.73). Also, there was no correlation between serum and salivary levels of IgA among the subjects. Conclusions: Serum IgA appeared to be better index than salivary IgA levels in monitoring response to treatment in patients with oro-facial carcinoma.展开更多
