Diagnosis and presenting features of autoimmune hepatitis at a central referral hospital in South Africa.

Introduction Autoimmune hepatitis (AIH) has scarcely been reported on in patients of black African descent. Similarly, few studies have focused on the relationship between AIH and Human-Immunodeficiency Virus (HIV) infection. Aim We aim to describe the presenting features of AIH from a single referral centre in a Sub-Sahara African setting. We also compare the presenting features of HIV-infected and HIV-uninfected patients. Methods This study was a retrospective chart review. Patients were included if they fulfilled criteria for the International AIH Group simplified score for probable or definite AIH, were 18 years or older at inclusion, and attended the adult Gastroenterology clinic at Inkosi Albert Luthuli Central Hospital (IALCH) for the period 1/1/2015 to 31/12/2020 on at least 2 occasions. Results Forty cases were included, of which 33 (82.5%) were female and 33 (82.5%) were black African. Median age at diagnosis was 26 years. A diagnosis of a coexistent autoimmune disease was made in 22.5% of patients, with Systemic Lupus Erythematosus (SLE) being the most common (12.5%). Sixteen patients were HIV-infected, all of whom were female (p =0.03), with a significantly older age of disease onset as compared to their HIV-uninfected counterparts (median age 38 vs 17.5 years, p <0.001). Conclusion AIH is a disease most commonly affecting young females. Female sex and older age of onset is associated with AIH in HIV-infected individuals.

A fourteen-year audit of surgery for inflammatory bowel disease at a tertiary colorectal unit.

BACKGROUND: In South Africa, inflammatory bowel disease (IBD) is increasing in frequency. The purpose of the study was to document our experience with the surgical management of patients with IBD and describe the cohort undergoing surgical management of IBD in a KwaZulu-Natal province tertiary state sector hospital. METHODS: Retrospective analysis of a database of patients undergoing surgery for IBD. Demographics, site and disease duration, surgical indications, management and outcome were analysed. RESULTS: Of 397 patients with IBD, 136 had Crohn's disease (CD) (African 13, Indian 78, Coloured 10 and White 35) and 261 had ulcerative colitis (UC) (African 67, Indian 158, Coloured 9 and White 27). Eighty-six of 136 patients with CD required surgical referral. Ileo-colonic CD was most common and non-stricturing/non-penetrating disease behaviour predominated. Seventy-four patients with CD underwent 76 abdominal surgical procedures with in-hospital mortality of 3.5% and a morbidity of 20.9%. Twenty patients required anorectal fistula procedures. Recurrence occurred in nine patients (10.5%) and malignant transformation was seen in three patients (2.2%). One hundred and sixty-three of the 261 patients with UC had pancolitis. Failed medical management was the most common indication for surgical referral. Fiftyone patients with UC had surgery, (age 44.5 [IQR 27-56] years). Forty-five patients underwent 63 abdominal surgical procedures with an overall mortality of 17.7% and a morbidity of 39.2%. Colorectal cancer was seen in 10 patients (3.8%). Laparoscopic procedures were undertaken in eight CD patients (10.8%) and 29 UC patients (39%). The median hospital stay was 7 days for both open and laparoscopic resection. CONCLUSION: IBD is not uncommon in African patients, with UC being more frequent than CD. Postoperative mortality and potential for malignant transformation are higher for UC.

Gastrointestinal common variable immunodeficiency presenting with symptomatic hypocalcaemia ­ a case report

Common variable immunodeficiency (CVID) is a rare form of severe immunodeficiency manifested by recurrent bacterial infections with several gastrointestinal manifestations. Herein we describe an unusual presentation of CVID

Severe iron deficiency anaemia caused by hookworm infestation - a case report - case report

Iron deficiency anaemia is a common clinical problem referred to gastroenterologists for diagnostic evaluation. While hookworm infestation is a known cause of chronic gastrointestinal blood loss, affected patients are usually asymptomatic and only 10% develop anaemia.1,2 Herein we present a case of recurrent profound iron deficiency anaemia caused by hookworm infestation

Colonic perforation following endoscopic retrograde cholangiopancreatography-associated pancreatitis.

We highlight a potentially lethal complication of acute severe pancreatitis that may not be suspected in severely ill patients. A 41-year-old woman developed acute severe pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP) for suspected choledocholithiasis. When her condition deteriorated dramatically after 2 weeks of intensive medical management, a computed tomography scan and water-soluble contrast enema examination revealed a large colonic perforation and associated collection in the right flank. Surgical management included an extended right hemicolectomy and a second laparotomy to attend to soiling at the surgical site. She survived and was discharged. Colonic perforation is a recognised complication of pancreatitis that carries a high mortality. It may result from a combination of ischaemia to the colon and a direct effect of noxious pancreatic enzymes. Almost all cases are only diagnosed at laparotomy. In view of the current trend of non-surgical management of pancreatitis and associated complications, colonic perforation should be considered in patients who deteriorate or fail to improve. To our knowledge this is the first case of a secure pre-operative diagnosis of colonic perforation due to to pancreatitis.
