Congenital diarrhea and enteropathies (CODEs) are monogenic disorders causing early onset of intractable diarrhea. Their diagnosis and management are challenging. With the availability of commercial next generation genetic testing, we are now better able to classify and manage these disorders. The authors present their experience with 4 cases. Two patients had congenital tufting enteropathy (CTE) and 1 case each of microvillous inclusion disease (MVID) and trichohepatoenteric syndrome (THES). Age at onset varied from 3 to 38 d of life. Light microscopy and electron microscopy of duodenal and rectal endoscopic biopsies were consistent with the diagnosis. Genetic evaluation was possible in 3 cases indicating causative mutations. Two children (CTE and MVID) were alive at last follow-up. The authors suggest a stepwise approach to the diagnosis and management of these disorders in the Indian context.

Case Report: Neonatal onset intractable diarrhea and hypoproteinemia due to intestinal malrotation and chronic midgut volvulus.

Congenital diarrhea and enteropathies (CODEs) are a rare heterogeneous group of inherited disorders that typically present with severe chronic diarrhea during the first weeks of life. As a broad range of illnesses can present similarly in infants, establishing a definitive cause for CODEs is challenging. In this report, two infants were suspected to have CODE, with neonatal-onset chronic diarrhea and protein-losing enteropathy finally found to be due to intestinal malrotation and chronic midgut volvulus.

Congenital chloride diarrhea (CCD) is a rare autosomal recessive disorder resulting from mutations in the SLC26A3 gene, leading to significant electrolyte imbalances and watery diarrhea starting in the prenatal period. Although prenatal diagnosis is ideal, many cases are identified postnatally. This case report details an 18-year-old primigravid lady in her third trimester who presented with severe polyhydramnios and fetal bowel dilation observed via ultrasound.

The small intestine bacterial overgrowth (SIBO) is a clinical disorder resulting from colonization of the small intestine by an excessive number of microorganisms or by unusual microorganisms. When they are methane producers it is called intestinal methanogen overgroth (IMO). Known risk factors are congenital or acquired anatomical alterations, motility alterations, some systemic and autoimmune diseases, those that cause alterations in biliopancreatic secretions, hypochlorhydria and some drugs.
