Irritable bowel syndrome (IBS) is a widely recognized disorder accounting for up to 50% of referrals to gastroenterologists in the Western world. Existing literature had suggested that its prevalence is low among native Africans. The objective [corrected] is to document the prevalence of IBS in this environment. A cross-sectional study of clinical students at the Jos University Medical School and the School of Medical Laboratory Technology in Jos University were cohorted. Questionnaires based on the Rome II criteria were administered to 330 students (221 males and 109 females). Irritable bowel syndrome was present in 86 (26.1%) of the subjects, being present in 58 (26.4%) of the males and 28 (25.7%) of the females respectively (OR 0.97, 95% CI 0.57-1.63, p = 0.89). The mean age of subjects with IBS was 26.3 +/- 4.0 years and that of subjects without IBS was 26.5 +/- 3.8 years, p = 0.6. The majority (54.8%) of the subjects did not consider their symptoms as illness and therefore did not seek any form of care. More males sought medical care compared to females (19.6% vs. 3.6% respectively, p = 0.02). Depressive symptoms were present in 21 (24.4%) of subjects with IBS compared to 36 (14.8%) of those without (p = 0.06). Irritable bowel syndrome is a common disorder in the student population of a medical school in Northern Nigeria.

The purpose of this study was to determine the point prevalence of depressive symptoms, using the PRIME-MD questionnaire, and irritable bowel syndrome (IBS), while comparing the Rome II to the Rome I criteria, in patients with fibromyalgia (FM) and rheumatologic controls in an outpatient setting. The prevalence of IBS in FM patients (n = 105) was 63% by Rome I and 81% by Rome II criteria. The prevalence of IBS in controls (n = 62) was 15% by Rome I and 24% by Rome II criteria (FM vs. control; P < 0.001). Depressive symptoms were met in 40% of FM patients and 8% of controls (P < 0.001). The coexistence of IBS and depressive symptoms in the FM patients was 31% (Rome I) and 34% (Rome II). The prevalence of IBS and depressive symptoms was higher in FM patients compared to the control population. Identification of IBS and depressive symptoms in FM patients might enable clinicians to better meet the needs of this patient population.

The etiology of irritable bowel syndrome (IBS) is complex and multifaceted. Psychosocial factors play a role in such a process. Several reports suggest that IBS patients have increased psychopathology scores as compared with population controls. The influence of depressive symptoms on rectal sensitivity thresholds vary across different studies. The influence of predominant bowel habits on rectal sensitivity thresholds as determined by barostat-based investigations is not well established. The present report aimed to investigate the influence of depressive symptoms on rectal sensitivity in different subtypes of IBS patients (diarrhea/constipation-predominant vs. alternating subtypes). Depressive symptoms correlated well with first pain sensitivity threshold in alternating patients (n = 8; [rho] = -0.77; p = 0.02) but not in diarrhea/constipation predominant symptoms (n = 11; [rho] = -0.44; p = 0.27). These data suggest that depressive symptoms might impact pain thresholds differently according to the subtype of IBS.
